If you moved it to a FAT16 or FAT32 volume, you might not have gotten all the file as FAT16 has a 2G file size limitation.

Re: os that rather uses the gpu?
ew) fields where a known capability is only now capable of being explored. Optical computing, 3d shading, broadcast 3d, and other immersion technologies add new requirements to the GPGU's being discussed. Motion coupled with 3d means that the shaders and other elements need greater processing power, and greater through put. Their architecture is undergoing severe redesign. Even microcontrollers are expanding their reach via multiple processors (via things like the propeller chip for example). I am a test applications consultant. My trade forces me to continuously update my skills and try to keep up with the multitude of new architectures. I have almost no free time, as researching new architectures, designing new algorithms, understanding the application of algorithms to new tests, and hardware design requirements eats up many hours every day. Fortunately I am and always have been a NERD and proud of it. I work at it. Since you have a deep knowledge of your requirements, perhaps you should put some time into thinking of a design methodology other than those I have mentioned or those that you know, in an attempt to improve the science. I am sure many others would be very appreciative, and quite likely supportive.

I like my systems to be local. I program them, I explore them, I sometimes hack on them with software, hardware, or a combination. I occasionally take one of the off line and use it for a program dump, or just to mess with ethernet stuff without impacting my network. I have private files on my system, and lots of works in progress. I sometimes do customer work on my systems (if they permit it), and the data files, simulation files, pattern files (I test SoC devices) can consume up to 20G/device. They don't compress well, due to the size and variety of the data, and I often have device data for 10-12 devices on line at a time. I do not have that all the time, it is "burst work", and consumes trememdous amounts of disk space sometimes for hours, sometimes for days and in a few cases weeks at a time. A 500G disk is about $200, lasts me an average of 3-5 years, with no other costs. The backup is a similar disk, via a plugin usb, firewire, or sometimes mounted. Total cost for supporting 5 years data, $400. A cloud system where I use that much bandwidth, and storage runs about 3500 for the equivalent usage, and some of the things I do would not be permitted by the cloud management for fear I would mess things up, and I occasionally do (have you written bugfree programs of any significant size?) Moreover you pointed out one of the real issues: month to month rental or lease or whatever you want to call it. And that is not counting the connection costs, storage premium if you are a non-standard user, or the lack of control, or the subject to search of the on line data because it falls under different jurisdictions. In addition, the security of encryption on a server system must by design be reduced in class for any given equivalent algorithm on a private system, due to the available resources to hack at it. IT folks love the idea of more control, less diversity in program support and all the other control they can exercise. The guys who make a real difference in IP are cost out of the equation, because they don't fit the parameter of the "average user". In addition the down time becomes universal instead of private. In a time when we are threatened by terrorists, putting your whole organizations software and data in a big "basket in the cloud" seems like a recipe for disaster. And it is a disaster that would make the financial melt down look tame. A single EMP weapon could disable or destroy multiple companies in a signal region. A domino economic effect that could have catastrophic implications. I watched a very good company have a big breakdown when their old server system with dumb terminals went down. The costs, and impacts nearly put them out of business. If they had been smaller it would have. I have no doubt that companies will embrace the cloud. At least until it all comes crashing down around their ears. PC's became dominant precisely because centralized solutions were an inhibiting factor on business, and personal schedules. Some lessons are too soon forgotten.

Hi, Craig, While those of us who use lots of applications may be familiar with the general concepts and will prowl a bit to get the right combination, those who use computers only for a task just what to know how to do the things they need to do. This is no way unfair. Do you know that the car has a differential or what that does? The car would not work without it, but it is not part of the knowledge you need to drive the car. But you do need to realize that the wheels rotate one way on one side and the opposite on the other and that they run at slightly different speeds, if you are going to race. That small bit of knowledge along with other similar bits would make you the exception on the course and give you an advantage. It is the same with computers. To say someone is incapable is a self aggrandizing statement, and implies that you are better than the gentle person in question. Maybe you are, but probably only in some areas. ditto for me. I excel in some areas and not so good in others. But that is human. The point is, though, that for the computer to be useful, it must meet the needs of the users, not the developers. It is a vital distinction. A good engineer listens to this kind of feedback and tries to come up with a solution. A foolish manager will denigrate this kind of input, and loose credibility with both staff and customers, as well as doom his product, whatever it might be, to obscurity. I've worked for or with some of those from time to time, and it is an exercise in design and engineering futility. So be open to the input, try to think how to help improve the situation, and make our beloved linux more powerful and more useful. And to be honest, good documentation is a major weakness in Linux on all fronts, from the OS itself, to the utilities. There are not enough books and not enough well written on-line tutorials to really help the novice, and those that do exist don't seem to ever be updated (except for the Wiki's). This is all just my honest opinion based upon my personal experience.

If you take the wheel off one side of a car and put it on the other, its direction of rotation changes, because it is mounted to a rim that will only go on with same side against the hub. Thus I can say that the wheels do indeed rotate one way on one side and the opposite on the other. You said it yourself, clockwise on one side and counter clockwise on the other. It is an engineering function. And it is not just cornering where the wheels rotate at different speeds, but all the time. Tires wear, so even if they started out measured to microscopic tolerance, over time they would be different diameters. This means the wheels rotate at different speeds even going down a straight road. Cart wheels actually rotated independently of the axel for this very reason. Look at the old wagons, or even roman chariots, the axel is a bar, but each wheel rotates on a bearing on that axel. Some basic vehicles use a solid axel and just put up with the stress on the axel and wear of the wheels, but most alleviate it in some way. And I would not want to be your mechanic.

If one were to look at the curve for say the Wright Flyer, to the Blackbird, what would be the maturation line there? We went from 0 to 3500 knots in just about 55 years. The evolution, from the Kite like stick and cloth to stick and cloth with frameworks, to sheetmetal and rotary engines to sheetmetal and metal chassis and jets, and to composite materials and titanium with scram jets in just 75 years, and no one would think of trying to retrofit an ejection module from the blackbird to a wright flyer ;-) Whereas the genesis of the modern general purpose computer has spawned billions of devices within essentially the same time frame of the airplane (maybe a bit shorter, but one can never be sure what governments are hiding.) And while one might keep a Wright Flyer around, no one would expect it to do any serious work other than as an educational tool for budding aerospace engineers. I have programmed on PDP-11's and PDP-8's and also on microcontrollers that would run rings around them. Modern stuff gets built because there are uses and needs that the older stuff just cannot meet. Not that the older stuff has no value, just that its usefulness is not so wonderful when compared with the new kids on the block. Costs however can certainly distort this picture.

HP photosmart 1215 printer issues
Hi, everyone, I am also having a printer problem. I let my printer run out of ink and let the messages queue up for a week, then bought the cartridges. I plugged one in and the queue won't restart, and shows the message about the printer being low on ink and the queue stopped. I have also tried the tape over bits fix and repeatedly powered up and down the system and printer in various combinations, with and without the cable in place. I really don't want to loose the stuff in the queue, so I am hesitant to go any farther without help. Hplip shows the new and correct ink levels. Cups says it has stopped the printer due to low ink, but then says the printer doesn't report marker levels (clearly untrue because hplip finds them) I have finally gotten hplip to initialize the queue and show it as accepting jobs, but I am out of ideas, out of web based solutions, and unsure if the f12 patch will install on F11?

The second took 3 weeks, and I ended up having to go to the top version of windows 7, an additional 100+US$. I haven't upgraded to F15 yet, but the other tools I use on a daily basis are all installed and working, and the reload time to get everything going on F14 was 8 hours, not counting the download time. If you add the download time and the upgrade time over DSL, it took a total of 23.5 hours. I routinely use over 30 applications on Linux, and only 6 on windows. So guess which I prefer. My Linux systems are still the best in my work, in my hobbies, and only fall short in gaming, but mostly I haven't looked up any Linux gaming sites, because I only really like one game, Age of Empires III, which I play on Windows by dual booting my computer.

And while you may not think it is easy (it is not a trivial program to write is the meaning I think you inscribe to the process), running the program was quite simple, and it did recover my files.

Re: Brain fart: no format option on a pen drive pop-up menu?
in the count of allocated segments, the file name is no longer reported by the file system, and to the casual user the file is gone. Enter a requirement for security, and things are different. Using recovery tools, those "deleted files" and "formatted disks" are still full of data. And moreover, the file segments contain clues that will allow the linkages to be recovered. Thus a formatted disk or a deleted file can be recovered. To be secure means to remove all traces of the file or to completely clean the disk. With today's disks containing Terabytes of information, cleaning one can take forever. It takes several varieties of writing to the disk to completely obliterate any trace of the file data, to get the idea, just think of what the disk is designed to do. It is designed to hold the magnetic fields for decades. It will not give up that magnetization easily. Moreover, the longer the data was in place, the more embedded it is into the disk coating, at least until the coating begins to mechanically degrade. Disk forensics will recover any formatted disks, and can recover files, even after they have been overwritten a few times. Understanding this is vital if you wish to provide security to yourself or your users. In most circumstances, the only way to ensure the loss of all data on a disk is to physically destroy the disk with fire or mechanical shredding. Enter solid state media. The new flash products rely on physics for storage. The data is permanently installed into what you could consider electrically isolated canisters. To physically erase that data, a much greater change in power is required, so the flash systems use a dc to dc converter to produce a stronger voltage to overcome the storage and erase the data. The same method is used to write new data. But a cell can only be written to a "one" state, or to a "zero" state, depending on the design. Therefore to write a bit into a block, the block must be temporarily stored, the block erased, the new bit written into the temporary copy and then that block written to the blank segment. But because the erase and write process are physically incrementally destructive, additional steps are taken to "level the usage" thus the block you write is typically not physically the same block you erased. That means that data is left in various places over the solid state device. Unfortunately (if you are security conscious), the bits are not random, they are not totally erased, and they can be recovered using a different set of forensic tools. Thus the format, delete and other file and file system utilities have even less hold on the data than with rotating disks. Being familiar with these systems and their internals gives you an edge in holding your own on personal security and system security. For example, one early virus would just mark various segments of the disk as unusable. This prevents the disc control software from reading or writing to that segment. It can allow an intruder to secure a bit of your disk from your use. This can be used to hide a virus or to hold copies of information, for example from a key stroke tracker or mouse tracker. That information can later be recovered by the virus and transmitted clandestinely to a remote host(s). Understanding the underlying mechanisms allow you to be able to better understand the strengths and weaknesses of the systems you use. Feel free to correct me where you see errors, as this was just off the top of my head.

The bits that don't they can google or ask you and you can google. For example, the setup of the system has several good step by step guidelines on Fedora.org. Your browser, firefox, has a link that will take you to the Fedora website, and there are links there to various support bits. Each application, Firefox, OpenOffice (or OO), the various games and all applications each have their own supporting groups, most are supported by one of the code development sites, and they support manuals, training links and Frequently Asked Questions (FAQs) to help novices on their software get up and running. Fedora is unique only because it rotates software frequently, about every 18 months for the release cycle with about 36 months support. So if you go to Fedora 13 today, it will be fully supported for another year roughly before Fedora 14 comes out, and then supported for 18 months after that. The reasons to upgrade are due to the evolution of protection against attacks, new and better (we hope) software, and new developments in general related to computing. So to advise you, any question in computing can be answered, but first you have to phrase the exact question you want answered. Fedora is a support organization for one particular flavor of the Linux Operating System. The things you do on a computer are applications. Fedora gathers a common subset of these applications and publishes the works as a release of Linux. Fedora as a group supports the OS. The applications are supported by their own Special Interest Groups, which are hosted on various software development sites. You can ask here to get guidance to some sites that support the application, and sometimes you can get very specific answers, but the applications are truly supported by their own groups. Just as if you bought Adobe Photoshop for your Microsoft system, you would have to go to Adobe to get specific answers about Photoshop. The best part if you have any budding computer scientists, is that the full source code of the entire system is available to examine, compile yourself and work on to see which piece does what.

You have decided on what they need. You may be right from the viewpoint of storage, but from the access point you could be way off the mark. A database's access speed is directly related to the disk locations of the various fields and structures. True you have given them storage at minimal cost to you, but what have you cost the customer? Do you even have a way of benchmarking the search times you have impacted?

When you are moving data around, do you examine the lifetime of the storage, or do you know the level of urgency when when that particular piece of data is needed or how it should be accessed?

The change continues to accelerate as well. > However, the network you discussed doesn't fit what most of us have at home. I'm lucky to get 6Mb up and 1Mb down. I could go with a cable solution and get 5M and 5M, but that is a bunch of orders of magnitude below the network you specified the cloud you bench-marked. Moreover, the partitioning of data to utilize the other processors is not just a thread cast from most versions of Windows. That has to do with Windows low level design. It can be tricked into doing that, but there are other burdens that arise and have to be coded around in one form or another. And as to what you said about the local OS, I don't know if that is strictly true or not any more, or at least it certainly doesn't have to be. When the system has multiple processors, several could be the app machine and the other the OS, and the partitioning could be fixed or variable depending on the software design. Of course all the OS interface to system storage would have to be re-entrant and double buffered to accomplish that. But in essence I could implement a small cluster with a file server over a local 100 to 100G Ethernet and get that end of it sorted. If the server has multiple processors with individual SATA, and I have separate page swaps or hardware memory swaps, I have whipped the basic speed limits. As to parallel processing applications, that still depends on the application casting threads to utilize the additional processors, but with cloud infrastructure, the latency of the cloud becomes an issue. If the cloud is local, that is one color cat, and if the cloud is a central control use, that is another cat, and if the storage is distributed, another tail to both cats. More over, why on earth would I pay to run a computer on an hourly basis? This is simply a smokescreen to add costs to the consumer for big software and internet companies, and it is being fed via spoonfeeding to the colleges developing designs. Given equivalent connect speeds, a local network beats a distance network every time, until someone gets quantum links working. But if that works, we don't need the wires any more do we? I don't pretend to know what's coming, but I do know that when stuff is outside my house it can be priced annually, it can be arbitrarily withheld, it can be surveiled, it can be compromised by those who have direct physical access, and it is not something I really want or need.

And as far as understanding, you may be right, but I have been working in and on computers for about 40 years, and there is not much new out there.

Things are getting really messed up on Fedora 14
Hi, guys, First it was evolution, and some poor slowdowns with other things, now it is firefox, where I cannot set the home page. I have tried using edit>preferences and typing it in, selecting the page I want and selecting edit>preferences and selecting use current page, and I hav tried dragging the token to the home button. None of these methods work. What on earth do we have to do now to set preferences? Is the history really being erased? Are our systems doing strange stuff? or is it just my system? By the way the problem of not saving the separator position in evolution has come back as well. Are Microsoft engineers "helping" us with our applications now?

Using the suggestion to set the home page in about:config did not work.
It would change it while the browser was open, but close the browser and
reopen it and the setting would return. I created a new profile, and
found that the home directory would take, but it wouldn't open it until
I clicked on the home button. But this was helpful. At least the new
user did not change the home page on me.
I opened the .mozilla/firefox/*username directory and did a grep for the
bad home page. Turned out there were two files that listed it.
The first is prefs.js. It warns that if you edit it with firefox open,
it will be rewritten. Apparently this is what is killing the setting in
about:config.
The second one is user.js. It had only one line:
user_pref("browser.startup.homepage", "stickyhomepage");
Changing stickyhomepage (my substitute for my home page) to the one I
wanted in both files, and eureka, it works as desired.
Deleted the new, unwanted profile and things are peachy again for now.
Question, where did the user.js file come from?

Les H

Hi, Jon,
Interesting that these pages never came up when I was searching for
preferences stuff using google. It is valuable information. The
user.js file should be mentioned somewhere on the about:config page I
think, to help people having problems. I don't remember ever setting
this file up myself, so the next question comes, where did this file
come from? I will have to see if I can find the source of the user.js
file. Maybe a new round of Google will help.
I struggled with this stupid problem for many days before I resorted to
asking the list.
I have had a really bad month from mid Dec to mid Jan with all kinds of
electronics failing. I have replaced at least 6 major pieces of
electronics, all with issues, from this stuff here to Windows 7
(re-vista maybe?) to remote controls failing (car, garage door, TV, VCR,
and DVD player.) If I have seemed a bit scrambled, it is because the
electronic gods are blowing my fuses.

Les H

You understand it correctly. Once I changed user.js to the page I
wanted, everything was happy. Maybe I'm a bit dense, but why would one
want two means to set a preference, when the hidden one overrides the
normal one?

internet intermittent very long message
Hi, everyone, I am experiencing internet intermittency. The same computer booted under windows performs very well, but when running Fedora 14 is very poor. Videos will only partially load, email (evolution) gives "error downloading mail", photos and graphics will be interrupted before they complete, etc. etc. tcpdump shows groups of ARP requests about 1 group per second requesting the users on my network respond in idle (only tcpdump accessing the network with possibly nntp.) and that's it. I have cleared out the various directories where cookies, temp files, flash stuff and some downloads are saved, Checked the internet connections by replacing the cable (not really expecting this to change anything since windows works), and checked various settings according to AT&T (who do not support linux at all) and looked on line at various suggestions, all to no gain. Basically I don't know what to look at next, and googling has not returned much in the way of help. Mostly a thread about memcpy, which may or may not apply.

RF is usually specified to 50 ohms regardless of the actual impedance (0dbm rf is 1mw on 50ohms), and a transformation is needed to arrive at the voltage, current losses for other impedances. Some VHF specs are at 150 or 300 ohms, and there could be a new standard developing for 600 as some patch antennas do have that high an input impedance.

And coding errors are not the sole issue. Logic errors, later edits, production modifications, and support editing also contribute their share. Even Object Orientation won't relieve all problems. I recently looked at a program where an object pointer was set to null in initialization, but later code would try to open a file that the pointer supposedly referenced, with no check for the null. This is a logic error, but could be just as devastating to the system, but would not be found by most code reviews. Moreover I often see object orientation espoused as a cure for these ills, but it is not. If you open up a "mature" C++ program and review the objects used, and really dig into their use i.e. trace the later defined objects, you can often find objects with what I would call stale code, that is functions that are not used in most cases in the dependent objects, and in some cases not even used in the original object any longer. There are probably tools that can detect these things, but I am not a proficient C++ coder, so I have not worked on using or developing support tools for that environment. But stale code offers opportunities for system penetration that do not otherwise exist. And since the use of pointers is still prevalent in code, misuse of pointers is definitely an abuse point. In short, programmers are fallible, and can make mistakes. Most such mistakes are small and have few if any consequences. Some are more problematic, and many are caught in alpha and beta test, or code review. But there is no panacea. We are all only human, and our code is the frail product of a human mind and human processes. When code is used in "mission critical" or "life support" applications, then every tool at our command should be used to verify that code, and even then mistakes will get through. That's life.

Firefox error
I am getting the following error on one of my fidelity pages: scs.fidelity.com : server does not support RFC 5746, see CVE-2009-3555 I googled "CVE-2009-3555" which reveled the following: The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. In my case this means I have a function that will not load from the fidelity website. And from reading this, maybe a "man in the middle" vulnerability. Does anyone know if this has been fixed? This would appear to be SSL or OS related from the description, so Firefox and Mono or Moonlight wouldn't seem to be the correct locations for a bug report, and since it is a "known" hazard, the bug must have already been reported. So my question is what should I do to rectify the situation?

I find it rather amusing that you choose a fictional character to quote in support of a barb, rather than the author who truly owns the words. But to each his own. Rex Stout might be pleased or offended, depending on how he identifies with his character. In any event the phrase "begs the question" does have common use according to Wikipedia, as has been quoted here: Many English speakers assume "beg the question" means "raise the question" and use it accordingly: for example, "this year's deficit is half a trillion dollars, which begs the question: how are we ever going to balance the budget?" Most commentators deem such usage incorrect.[10] 10. # ^ Follett (1966), 228; Kilpatrick (1997); Martin (2002), 71; Safire (1998). www.http://en.wikipedia.org/wiki/Begging_the_question retrieved 3/21/2011. Language grows by common use. As English has not become a dead language but rather thrives in many places in the world it continuously evolves. Language is what one uses to communicate, and at best communications via spoken or written word is about 70% useful, from my personal observation. Let us not discuss accuracy in spoken or written word, as no real capability exists to quantify the transfer of accuracy by words, although evidence to the contrary exists right in this discourse. We must abide by common use to be understood, like it or not. This is one reason that in centuries past, Latin was chosen to be a "language of science", unfortunately science seems destined to outstrip the capability of that long dead language to express the complex concepts being uncovered almost daily. The uselessness of grammar for some forms of communications has led to development of formal protocols in many areas, such as: police communications, aircraft terminal communications, inter-ship communications, international communications and even to the unusual shorthand that is quickly becoming formalized from twitter users. Rebelling against the formality of grammar also produces such delightful idioms as "That will go over like a lead balloon." Of course the various combined dialects such as Spanglish or patois fly in the face of formal grammar, yet the people using these forms of speaking and or writing, manage to live their lives and communicate with others quite well. And while I am not an erudite scholar, I love to listen to people and try to understand their thought processes and their backgrounds from the words they use and the mannerisms they use to express themselves. It is useful to remember that what constitutes good grammar in English depends on a great deal more than the simple declaration it is English, because of the number of wonderful countries and cultures using English as the basis of their discourse. It is even more useful to remember that here, many people from around the world can see what you have written, and while it is not quite stone, words on the internet tend to hang around for quite a while. Good grammar is useful, when you can find it, but communications exist without it as well.

I may be somewhat in error, but I think it will help you understand the point, and others will always be helpful in clarifying... In a debate (argument if you are less formal) a form of establishing your point is to say something that you believe is supported by the facts without examining the underlying facts too closely. An example of this: Social security is underfunded. That begs the question of what do we do to reduce the payout of social security. The first statement is in doubt because there are experts on all sides of this statement that do not agree that social security is under funded. But by stating it as a fact, the debater can turn the question so that a solution for a non-existent state of affairs becomes the topic, rather than social security itself which should be being discussed. Thus the debater has distracted the audience and possibly altered the course of the debate from the desired discussion to make a personal point. In common use and informal discussion, more correctly one could say: Social Security appears underfunded, begging the question of "What do we do to fix social security?" The difference is that the first is an intentional misdirection, done to deliberately lead the discussion to a desired conclusion without actually examining the facts. Colleges have formalized the debate, and attempted to establish rules of discourse, means of reducing the impact of such attempts at misdirection and misrepresentation with logical precision, at least as logical as one can get given the workings of various persons mental capacities, and given that various people have various backgrounds presenting facts to them that may forever be unknown to the large majority, either through intentional classification and secrecy or through lack of direct in-depth knowledge of the subject. In formal debates, one is supposed to rely on factual material, explain ones conclusions based upon the facts and not bully, mislead or misdirect the discussion. They have given names to the various tricks that manipulators will pull on the public to control the debate. The one under discussion here relates to a statement that may or may not be true being presented as absolute truth, then directing attention from the facts to a desired direct conclusion which may be totally the wrong thing to do, but is a direction the debater wishes to go. I hope this helps.

sinf compiler error I don't understand
First let me say, that while I have used C++ I don't normally use it for
my work and so am not throughly familiar with what it does, so if this
is due to a C++ error, please be gentle.
I am working on some DSP code I developed a long time ago, and now want
to port it to 64 bit. I have read several articles on the differences
in C and C++ between 32 and 64 bit, but this has me stymied.
Here is the smallest sample I have been working with to show the current
error:
#include
#include
#include
#include
main()
{
long double temp;
printf ("M_PI=%e\n",M_PI);
printf ("sin 90 = %e\n",sinf(M_PI/2));
temp=M_PI/2.0;
// the following line won't compile for temp
// regardless of how temp is declared (float, double, long double)
// printf ("sin 90 = %e\n",sinf(temp));
}
Clearly sinf is recognized, and compiles and runs. It returns 1.000 as
expected for M_PI/2. But the line that is commented out will not
compile.

The first response found the error -lm which fired up the linker with
the module. Apparently the compiler auto replaced sinf(M_PI/2) with a
constant and didn't throw the linker error, where as the second one put
in the call to the math library and threw the error. Adding -lm loads
the library.
I was compiling as C, but thought the error might have come due to my
miscalling gcc thus invoking the C++ compiler and missing something to
call the correct sin function i.e. sin/sinf/sinl etc. But I had written
good code, just misinterpreted the error and forgot the link argument.
I guess the C++ form as you used probably seeks to find any libraries
required by the code, preventing linker errors. That is probably a good
thing.
I will probably use a make file in the ultimate project and would have
likely caught the problem then, but the night before was an allnighter,
so I was foggy (and being an old fogey, that is double fog).

The system then hunts through a database of ID codes to find the appropriate control structures, at least the first time. If the disk has formatting and control software that must be loaded, then that software has to be read off the disk before its local controller can respond. Disk latency is milliseconds, and if the information is stored for retrieval by a fast system, the slower Z80 or microcontroller may require several revolutions to retrieve various bits of information. The partition table and other records must also be read, taking additional time. However, you are luckily working on Linux, and you are free to improve the software ;-) The disk drive controller software may not be changable, depending upon the design, and whether or not you have access to information about the controller architecture.

But there are limitations even there. As the content addressable lines are in essence a parallel bus or can be implemented by a high speed serial buss that all the processors listen to, and the interrupt is a serial line that is daisy chained in most implementations, the intermediate responses still require a single processor that answers the interrupts and checks the remainder of the response. Further, this is a specialized search and retrieval architecture, and as such it is more or less a dedicated architecture. That is not bad, but it is expensive relative to the total task a typical processor has to perform. Moreover each unit on the line is a processor in itself, which is a relatively expensive implementation for a memory array. But it did see sufficient interest that I think the 386 processor had some dedicated lines to use for that type of machine design. I haven't heard much about it lately. Modern hash, tree, and segmented search routines, along with relational data base development can nearly equal the performance with lower cost and a more universal architecture, depending on the database implementation, and of course, a universal architecture can be setup to perform the CAPP algorithm using a widely distributed architecture. At least that is my view for what it is worth.

It is psuedo random because it is derived from a static calculation, but it is random enough over large numbers of bits for some specialized uses. Also haveing it out to large numbers of places is useful for some kinds of repetitive calculations in computational analysis, since each multiplication loses essentially 1/2 bit. If you have enough bits to start with, then the loss won't show up in the final calculation. Some kinds of simulations require enormous calculation chains, which in turn means loss of accuracy. It is not that the accuracy of 1G bits (or bytes) of PI can be directly applied in the real world (getting A/D's that work well down to 32 bits is a challenge.) but the loss of precision in some types of research, in some real world chained calculations, and in some matrix math does become an issue.

issue running fsck DMESG clip included
Hi.
I am currently running FC12. I am working on upgrading my system and
going to a 64 bit system, because I know I have some issues in this
hardware (slowdowns, internet issues etc.) they have been niggling for a
few months now, and I have been gathering cpu bucks to replace it. So
first I wanted to run fsck to clean the disks, then do a backup, and
finally to replace the system and move to FC14 64 bit. First step did
not work.
I have seen messages in the boot process indicating errors in the ATA1
section, although the system appears to be working reasonably well
(given the niggling h/w errors I knew about). This is new.
I wanted to run fsck, so I booted from the install disk for FC12 and
opted for the command line without mounting the disks. when I attempted
to run fsck for /dev/sda1 I received errors that the system could not
run on an LVM volume. How do I overcome this issue? And if LVM's
cannot be checked with fsck, how do I ensure that I do not generate
LVM's on the new installation of FC14 (sorry, I know that is two
questions...) I will send a separate question for the LVM/FC14 issue.
Anyway, I could not capture the output message from the command prompt,
and wasn't bright enough to write it down. I will try it again if some
one needs the exact messages to help me.
regards,
Les H

Upgrading the computer issues (dual boot windows 7 with grub)
I purchased an AMD phenomII 6 core with 6G ram and 1.5Tb hard drive with windows 7 home premium already installed. I added a 500G cavier black drive for my linux system, and removed the windows disk temporarily during the install to ensure I didn't clobber the windows stuff (I need windows professionally), but I want dual boot, so this should work. FEL14 x64 live cd was used to setup the disk. I moved all of my older user directories from the prior FC12 drive to the new drive no problem. Now I need to set up the dual boot. Researching the net returned the usual stuff about hd0 and hd1, so I edited menu.lst. (see later listings of menu.lst and grub.conf) I do not see the menu presented. I don't seem to be able to get into windows 7 at all. So the question becomes, how to access the menu and get windows 7 to boot.

Evolution mess
Hi, everyone, Continuing my issues with moving to 64 bit and porting stuff, evolution has a phantom contact list. As you can see in the attached screenshot, the first "on this computer>personal" contact list doesn't appear to exist. The other one is the good one. I don't appear to be able to move the second "on this computer>personal" or even copy or move its contents to the first "on this computer>personal" list. Neither can I delete the first one, because the delete option is disabled in the menu. I suspect that there is an error in my personal .evolution folder that is causing this, but I am unsure about editing those settings without advice or a reference. My google searches have not turned up anything I could use. Any assistance or advice would be helpful.

This is the FEL released version of F14, and shows up as: Release Kernel Linux 2.6.35.9-64.fc14.x86_64 Gnome 2.32.0 Hardware Memory: 7.8GiB Processor 0-5 as AMD Phenom(tm) II X6 1035T Processor I have searched via google, and read the FAQ's on Evolution and no information appears telling where the personal setup has moved. I am willing to experiment with the files by hand editing if I have some place to look and can store backups so that I can restore the files. But since you said that the location has moved, and I have not seen where it moved, I don't know what to do next. I am going to prowl my file system right now to see what I can find.

I have tracked the setup and config files to ~.gconf/apps/evolution. In the Addressbook folder there, there is a %gconf.xml file (unique call having all these files named as %gconf.xml) Anyway, I edit the one in ~/.gconf/apps/evolution/addressbook, and I find that it has two entries: +++ <?xml version="1.0"?> <group uid="1162801071.10728...@localhost.localdomain" name="On This Computer" base_uri="local:" readonly="no"><source uid="1162801071.10728...@localhost.localdomain" name="Personal" uri="file:///home/lesh/.evolution/addressbook/local/system" relative_uri="system"><properties><property name="completion" value="true"/><property name="pilot-sync" value="true"/><property name="use-in-contacts-calendar" value="0"/></properties></source><source uid="1163129951.1854...@localhost.localdomain" name="Personal2" relative_uri="1163129951.1854...@localhost.localdomain"><properties><property name="completion" value="true"/><property name="remember_password" value="false"/></properties></source></group> +++ and +++ <?xml version="1.0"?> <group uid="1292063110.247...@school3" name="On This Computer" base_uri="local:" readonly="no"><source uid="1292063110.247...@school3" name="Personal" relative_uri="system"><properties><property name="completion" value="true"/><property name="remember_password" value="false"/></properties></source></group> + So far so good. Now in the first list string, there is a file referred to as personal2. This file operates as it should. The first name entry as personal does not. It doesn't appear to have a file associated with it. Since there is a personal address book associated with the second entry, I think all I should have to do is edit this %gonf.xml file and change the entry reference to match the second one. But that brings up a question of where the actual file is and if it is in the correct place? If it is not, then the next software update would mess things up again. If anyone can shed some light on this, I would appreciate it. How does the link mentioned, which appears to be 1292063110.2...@localhost.localdomain get resolved to point to the file?

And are you including administrative operations a back door? Is it impossible to administer a properly designed system without a back door? Some times good intentions and even debugging leads us astray. Code gets "left behind" that should not, or enabled when it should not, or even inadvertently promulgated when it should not. It has been shown that software can be developed and built into a compiler that will insert a back door into any code compiled by it. The original intention was debugging, but the technique has other applications, not all good. Do you know if your code includes such a back door? How would you detect it?

various errors related to configuration
I started with an evolution configuration error, and now a Firefox/Mozilla configuration error, so it appears to me that this might be a system level error. Maybe some file or directory permissions issue, or perhaps a generic configuration error. I tried using the Firefox ProfileManager to create a new profile, but that lost me all my bookmarks, as well as not changing a problem getting my home page to load at startup, in spite of that being the selection on the preferences page, even after creating a new user profile with the profile manager. Java won't run, even after reloading from the software add/remove manager. Next I went to the Java website to get the new package, and retrieved the jre-6u23-linux-x64-rpm.bin file. when I attempted to source that file I get: $ ./j*bin Unpacking... Checksumming... Extracting... UnZipSFX 5.50 of 17 February 2002, by Info-ZIP (zip-b...@lists.wku.edu). replace jre-6u23-linux-amd64.rpm? [y]es, [n]o, [A]ll, [N]one, [r]ename: y inflating: jre-6u23-linux-amd64.rpm error: can't create transaction lock on /var/lib/rpm/.rpm.lock (Permission denied) but the file appears to uncompress and be present as: jre-6u23-linux-x64-rpm but I am unsure of loading it with the prior error in existence. There may be other configuration issues as well, that I just haven't stumbled onto the situation where they will show up yet. Is anyone else having these kinds of problems? I haven't had this much difficulty since maybe my first Fedora installation. I know that this is all 64 bit, and that there may be some teething issues for me, but these kinds of errors, and the issues of moving all the configurations under a new umbrella with little background on why, where, premissions, access, and guidance doesn't give me much to go on. I know just enough to be dangerous, and apparently not enough to be able to find and fix the problems. Any further help would be appreciated.

Re: About programing, a general question
od examples of both power and complexity, and can produce quick simple programs that do useful things and represent real accomplishment. But remember my programming is focused on functional programming. That is programs that produce hardware operations in real time. I would also recommend reading a lot of code. There are a lot of oxymorons in code production. Self documenting code is one. If it were really self documenting we probably wouldn't call it code. Logical sequence is another. While many things take place in a logical sequence, when programming for efficiency, what is fast and what is logical will sometimes be at odds. Reading code and reading about code will give you an edge in these types of issues. Pick a language and work on it. If you get frustrated or need help, see if the language has a forum. Read it. Ask for help. There are dumb questions, but not to ask them is even worse. If someone blasts you about the dumb question, then tell them you don't know much and are willing to learn, but then make the real effort to learn. Programming is fun, challenging, nerve wracking, frustrating, and amazing all at the same time.

But the fact is that all languages rely on pointers. Even the beloved scripting languages so many tout, cannot exist without pointers. The fact is that all data in the computer resides in memory or on disk or some other file system. Every file system depends on pointers. If you look for example (using one of the oldest and free forms that is easily accessible) FAT 16, The base structure starts with the location 0, which is a pointer to a data store describing the disk. In turn, from that you find pointers to the partition table. From that you find pointers to the FAT table itself, and to the data. From the fat table you get an array of indexed pointers to data segments which are pointers to boundaries of data blocks, and from the partition table you get a description of the sector layout, the retrieval blocking and other information about the structure, which allow you to decode the FAT table and extract the data. The beloved object oriented folks have pointers built in, that are used to access the procedures that affect the objects. The objects are in fact structures, which are created in blocks and again pointers are used to reference that information. When you use an array, that is an indexed offset from a pointer. Someone said pointers break the typing. That is not true, if you do not break pointer typing to begin with. That is a pointer can be typed, and moreover someone who uses an integer for a pointer is voiding type control in his program. No knowing pointers means not having any clue to how the underlying structure works and leads to weak programming. I strongly encourage every beginning programmer to learn pointers, pointer usage and pointer math to understand some of the mechanisms that make programs break. A programmer who doesn't understand the strengths and weaknesses of pointers is like a plumber who doesn't know how pipes work and what makes a manifold. He can hack around, but he cannot diagnose when plumbing makes noises, doesn't flow correctly or even backflows. That is my opinion. Maybe I am out to lunch, but has anyone seen any language that didn't access memory?

I am beginning to feel really frustrated. Simple things are not working, things I know how to do I am not doing correctly, and even when I fix that I don't seem to get any response, up until now. I have put a pointer to the file in the correct location now, but it still doesn't load. Someone on another thread suggested the followign to enable flash: # mozilla-plugin-config -i But when I ran it I received: *** NSPlugin Viewer *** ERROR: /usr/lib64/mozilla/plugins/libnpjp2.so: undefined symbol: __gxx_personality_v0 Googling: mozilla __gxx_personality_v0 No help that I could see. Most references were to compiling with gcc vs gpp or g++. One was addressing an issue with pulse from 2005. Nothing current except one ubuntu entry which had insufficient debugging information. However the links to gcc and gpp and g++ issues leads me to believe this is due to lacking a library of some kind. Reading the entries the assistance provided was to null define __gxx_personality_v0, which doesn't seem like a good solution, and wouldn't apply in my case anyway as I am not compiling the code. I did not find any library defining gxx_personality_v0 in links. Any help anyone?

For example the 8080 was octal, because the first 2 bits had a specific segmentation of the instruction set, the next three could choose a register or memory and the final three would make a choice based upon the other two groups. In the 6800 and later motorola processors, the representation was hex, reflecting a broader register base and larger instruction flexibility. Now that we have 64 bit processors, and multiple cores, the next step will be a supervisor for the cores and then a new partitioning of the instruction word, and I expect a new notation, probably 64 base of some kind, because it will reflect the new reality of the core processors and their inherent capabilities.

I also must be showing my age ;-:) (showing the toothless, dentureless smile) Seriously, though the points you make about template classes, along with over use of inheritance, and bulky code in some classes makes C++ really a drag on high speed computing I think. I use C a lot, probably too much, but I don't do much in the way of huge programs. Most are 12,000 lines or less and I only get about 3 months to deliver them at most. Also the systems and people I deliver to, don't have extensive OOP experience and since they often maintain, or extend/maintain/modify the code, C++ would be a hardship on some of that, where as C's basic structure is a bit more challenging, but gives more direct control for their work. The largest code I ever personally developed was just over 40,000 lines.

Right, Alan, and then there are the odd languages like VBA (Microsoft's Visual Basic for Applications), LOGO, Prolog, Eiffel, Small Talk, and APL. Forth is sort of a different game as well, as are some of what once were called the fourth generation extensible languages.

Sorry, just haven't used it in a while, and when I have it was for some simple C stuff, no debugging or anything, just a few lines of code thrown together for a small task. I thought most of the underlying libraries (stdio stuff, standard math, order of evaluation stuff and so on were the standard C libraries, just called from within the C++ code as needed, unless the C++ code overloaded the functions. I guess I am really dated now ;-) and I've only been out of the formal work for about 5 years. I may have to get active again. Maybe C++ has outgrown some of the things that made me shun it. Is the context limitation on objects now universal? If an object is created with inheritance now, does the runtime code contain the associated links with the object core to link the inherited functions, or is this still a static table at compile time only? I have hundreds more questions now, but this is not the thread for them I think. Both Java and C++ broke for me due to occasional and unexplained loss of reference to global objects and associated public functions, resulting in difficulties building complex programs without some extra files and linkages in the past and I could not find any explanation of what I needed to do to make it work, which made me even more prejudiced against them than I wanted to be. In one Java class I created a nice little program which required a linkage of an object and its public functions from one file to another, but the code wouldn't support it, and neither the instructor nor any one in the class could find the problem. I still got a good grade in the class, but not finding and fixing that problem still sticks in my craw today. And that is why I do not recommend OO languages for newcomers. If the instructors cannot make simple code work, then a newbie needs to avoid that and build some success first before being thrown into that pit.

Even the friendly neighborhood geiger counts can be affected by environment and yield less than optimal noise. However there are some quite good white noise diodes available from commercial houses that do considerable analysis of their noise results, and will yield quite good histogram distributions and even multi-axis distributions. However the experiment you did was a bit biased in its setup if you modified the output to generate the two axis, for example limiting the binary data to say 8 bit numbers, they you essentially get a distribution running from 0-511 which would have a gaussian curve if the random numbers were uniform. Random numbers are a rather esoteric study in and of themselves, and understanding the limits of a particular algorithm or measurement is always helpful. Noise algorithms used in a noisy environment tend to produce gaussian results due to aliasing of local noise sources into the data, 60 hz or 50 hz is a common issue. If a wireless lan is present, it will produce some odd effects due to the headers and other protocol bits adding non random data into the mix. A common tactic of using the trailing bits of a PI calculation is also an interesting approach.

Re: FEL request: opencores and user demos
Hello, Chitlesh GOORAH, I am interested in doing PIC development with the one of the following setups: 1. PIKLAB Piklab, gpasm, gpsim, gputils, etc. 2. Ktechlab Ktechlab, gpasm, gpsim, gputils, etc. The primary devices will be: pic16f887 pic16f690 pic32 (not decided yet) I know that the 887 is not supported yet by some of the above, but I am not above getting my hands dirty and doing some coding or control or script file generation to make it work. I would like a good tutorial and documentation to begin the effort, but the stuff I have been able to locate on line is pretty thin. I can also do documentation. I am a test engineer who rose to Test Specialist inside of Teradyne, and my forte was writing program translators from one language/system/instrument set to another across Operating systems, platforms and languages (I am a polyglot programmer). I also developed training and manuals that are still being used by that company. I attempted to find which mailing list to subscribe to, by browsing the FEL portion of the Fedora website, but couldn't tell which group(s) would provide the types of information I would need. The environment I would create would ultimately be used by several programmers locally who have some C knowledge, limited assembly knowledge and no embedded experience at this time, so I have my work cut out for me. I expect the total effort to take between 6 and 9 months. At the end I would like to have the following: 1. A simple installable environment for pic development, plug and go. 1.A Examples for the PICs currently supported. These must be executable and tracable, and reflect reasonable programming practices. 1.B. Programming Templates similar to the ones furnished by Microchip. /** 8 months max to this point / 2. A simple file method to describe a new pic and enable its simulation, code generation, and simulator debug, so that new devices would require coding only when core processes change. 3. Documentation that would include coding examples and stepping through a bit of code to show the FSR's, variables, system operation, perhaps even the waveforms if the IDE supports that. Schematic capture compatible with the GEDA stuff would be ideal. 4. Internal linking to the Microchip website for documentation support, and adobe reader support for the pdf documents. 5. A manual explaining the operation of the system. I know that a lot of this already exists. I know this can be done, I am pretty sure about the possible time line, and I believe I have the generic knowledge to do it. What I lack is the specific knowledge about the tools, and I am a bit dense I guess, because the documents I have found seem circular in reference and not completely clear how the links are created and set up. I have PIC lab and Ktech lab both installed, and they both appear to more or less compile code, but the hooks to the other utilities seem quite bad. They do not seem to recognize the two PICs, the simulator is not integrated, although I can run gpsim from the command line, and some fonts are missing. Once I get to the right mailing lists, I can provide more information to the correct folks there.

Brasero headache
Hi, everyone, Brasero seems to have taken over all the shortcuts on my system. I don't often use the cd or dvd roms, but generally use the nautilus built in cd writer to create the disk images. Now Brasero has consumed all the shortcuts, and I cannot get it to play nice with my DVD (it never has). How do I get back to the original Nautilus default cd/dvd writer to create my image. I don't seem to be able to locate it as "cd/dvd writer" or "dvd*". regards, Les H -- users mailing list users@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
Re: FEL request: opencores and user demos
OK, here is what happened. I discovered how to make the drive respond correctly and was able to create a boot disk, for the FEL fedora 12 iso downloaded earlier. The disk was verified by the software (NTI CD and DVD creator in windows) and ejected properly with no error messages. Powered down the system and inserted the new disk and rebooted. I got the countdown message, followed by the filling drop graphic. after quite a pause on the graphic toward the last quarter of it, the system appeared to complete the boot process, then the following errors appeared: usb 3-2 device descriptor read/64 error -71 usb 3-2 device descriptor read/64 error -71 mount /dev/loop2: can't read superblock mount /squashfs/liveOS/ext3fs no such file or Directory mount /squashfs: not mounted mount: unknown filesystem type 'DM_snapshot_cow' *repeated 21 times 2 blank lines can't mount root filesystem Boot has failed, sleeping forever Since the write was verified, I tend to think this is not disk related. I did attempt the boot two times just to make sure it wasn't a fluke and got exactly the same results both times. Has anyone else loaded this disk?

e100 error
Hi, everyone, I have one older IBM system running F11. I am trying to upgrade the video card. I bought a PNY version NVIDIA GE Force 5200 PCI board to use. When I plug it in and connect the video, the system boots and goes through the full F11 bar display, the screen goes blank and after a few seconds I get an error message: e100:eth0 NIC Link is up 100Mbps full duplex ADDRCONF (NETDEV_CHANGE):eth0: link becomes ready which flashes for a few more seconds, then becomes stable with an underscore cursor beneath it. when I attempted to Google it, All I found were references to F12 (which this machine refuses to run anyway, I'm hoping for F13 to fix that). It appears though that hitting return when you see this message in F12 will let the machine proceed. Not so, when I hit return, the cursor moves down one line but nothing further happens. The changes recommended have to do with setting some options in some of the bootscripts. Here is one thread discussing the issue: http://bugzilla.kernel.org/show_bug.cgi?id=11998 However, this doesn't seem to fit. The only thing changing in my system is the adding of the PCI based video card. How can that affect the hardware setup of the NIC card? Moreover, why is the renaming taking place at all to begin with? Mac addresses are supposed to be unique. Is there a manufacturer or subset of manufacturers who are not following the rules, or have the number of cards exceeded the number of available addresses? But these questions detract from my base question:: How do I get my system to work properly with the new card? The reason I am doing this is to eliminate video streaking on the subject computer which occurs with the built in intel chipset.

I could log in, but not do anything. I restarted the system, and logged in as my admin user, opened the selinux troubleshooter and found that there were three problems, two with colord needing dbus read and another that I can't read my own handwriting to figure out again. Followed the advice and set the policy to set those using audit2allow and semodule -i as instructed. Then touched /.autorelable and rebooted. Next login I got "Could not create ICE listening socket
Evolution error
It appears the automatic importation of the older evolution stuff still has a bug or two. I wrote and sent the solved message, and it apparently went out, but I received the following error message: Your message was sent, but an error occurred during post-processing. The reported error was "Failed to append to mbox:///home/lesh/.local/share/evolution/mail/local#Sent: Invalid folder URI 'mbox:///home/lesh/.local/share/evolution/mail/local#Sent' Appending to local 'Sent' folder instead.".

Desktop desires and questions
HI, everyone, I know that this has been discussed before, and I will go back and read more of that. I want more efficient use of my desktop. Pretty is nice for most people and of course design driven types, but I am a technophile, closer to Sheldon (of big bang theory) than normal people. I know that. Here is what I find in using the desktop as it exists in F16: The need to click to get to the computer is annoying at its very best and a real vocabulary expander in normal use. Every time I use one application and I want to access another I have to click "activities" my windows shrink and I have to move the mouse to "applications" click I get the menubar I should have in the first place of course its on the opposite side of the screen and I now have to mouse over there and click "topic" (and the applications are somehow scattered by my view) which should be a pullright to a menu but which sprinkles applications all over the screen. mouse to my application click "my application" And finally my application comes up. Oh, yes, I do have a 23" monitor, so the route of crossing the desktop will get worse when I upgrade or go to multiple monitors later this year. This is so ergonomically inefficient, so slowing that it adversely impacts my progress. Anyway, that is only the most irritating bit I have found so far, but it is worse. I don't see anyway to move the icons, change their sizes, move them to various menus, expand the menus, or do anything at all to change the current layout which is not at all conducive to my work. I put this off long enough to hope that these issues had been addressed, but they are not. I don't want to start a flame war. I don't want to start a debate about desktop managers (I know there are many out there) Nor do I wish to castigate anyone. I want to just make the thing do what I want without a whole lot of deep investigation into XML files. I want to know where the documents and or utilities are that will let me do something to improve my working environment and get back to efficiency. If you have useful information, please send it on. I am sure I am not the only one who wants this information, nor should it be hand editing xml files, although if that is the only method, I will do it until I get too frustrated with Fedora. AT this point I will not give the disks to a friend who wants to use Fedora, because he is sight impaired and this desktop will not work. That is a real affront to disabled people and should spark some kind of action by everyone involved. Please keep it civil and provide solutions for this desktop, don't say change desktops, don't start flaming, just help me and others get this thing to do what we need. With all that said, the basic needs as I see it are: 1. a way to get a list type menu instead of icons 2. a way to move the icons (if a list is not possible) or listing to different top level applications menus. 3. Get the applications menu on screen all the time as a pulldown. 4. ability to change icons by right clicking on the current icon and selecting a "change icon" menu which will open a file navigator. 5. remove the "activities" switch and put the windows and applications buttons in its place with pull downs optional. 6. remove the "favorites" and just let us put the icons on the desktop if we so desire. 7. do whatever else can be done to allow font selection, including fontsize as well as icon size for the desktop. This is an HID requirement anyway. 8. Stop the messing around with the open desktop in any way whatsoever. It is distracting and interferes with efficiency. Oh, and I did do some Google-ing, but got very little useful information. Since Fedora is the cutting edge, lets make it cut a good swath. Thanks.

Installing MPLABX on F16 SOLVED
I have already gotten this to work, but this is my process in case it will help someone else. 1. download the latest MPLABX from microchip 2. run the installer 3. touch /.autorelable just to ensure SELinux picks up the files 4. reboot 5. login as the user 6. got the OH no message. 7. reboot (as the system was basically disabled) 8. login as admin 9. run SEtroubleshooter 10. follow the instructions to audit2allow and semodule 11. touch /.autorelable just insurance 12. reboot 13. login as user 14. login successful, but another selinux error on colord 15 repeat steps 3-13 to get successful login I haven't used it yet, but will soon. I think it is OK, as it comes up alright at this point in time.

I now have gigantic fonts, a bit too large, so I will have to play with it a bit. Unfortunately it doesn't change the names associated with the icons sufficiently, which I really need. I still need to research which setting affects that. I know the favorites bar, I have about 20 applications I use routinely, and several places I need to directly access, so I am unsure if the "favorites bar" will expand to show that or will I just end up with yet another scroll bar or other move/click to deal with. Maybe KDE is the answer, but it seems like from what I see on the Web that KDE is headed this route as well. So based on that I think getting all of us to input reasons for our dislike along with suggestions and maybe some day triage to consolidate the list, we might actually get some thing useful out of it. Thanks for the suggestion and I am working on the interface issues myself. Maybe a switch that says "my custom DM" will be the outcome.

Gnome-tweak-tool issues
I have added gnome-tweak-tool to my system. However I have some problems with it. First run from the software install tool went OK. Made changes to various fonts, and they took effect. However on subsequent runs I had to start it from the command line, and it hung up, but I also got a few warnings and errors which are listed below. Is there any package I need to install to overcome these issues? Second and subsequent runs: $ gnome-tweak-tool WARNING : Schema /usr/share/glib-2.0/schemas/org.gnome.shell.gschema.xml missing summary text: 1 WARNING : Schema /usr/share/glib-2.0/schemas/org.gnome.shell.gschema.xml missing summary text: 0 (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed (gnome-tweak-tool:2166): Gtk-CRITICAL **: gtk_widget_get_preferred_height_for_width: assertion `width >= 0' failed -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

I agree with some of this, but the second point that people expect you to know their hardware etc. just likely don't realize how much information you need to help them. I worked in support of complex systems for about four decades, and everyone I helped just did not seem to realize that the hardware, software, programming language etc. is all a system, and to understand a systemic problem you need the information about the system, not just the problem or error message. And by the way, the people I was helping were all engineers of one stripe or another. If engineers cannot realize this, how can a normal consumer who is say a financial person be expected to know it, or act in an anticipated way?
