I played around with it in the past, not recently though.
MAC-based access control lists are simple and lightweight. Which is why I use
them for WIFI networks (apart from the guest-WIFI). But I don't consider them
secure enough to only rely on those.
I only actively set MAC-addresses for VMs to avoid duplications. I don't see
the point in setting them specifically as they tend to be unique in my
experience.
Only other reason I can think off for changing the MAC-address is to get around
a MAC-based filtering.

[gentoo-user] Firefox 38.1.0 :-(
Hello, Gentoo. Over the course of the last 24 hours, Firefox 38.1.0 became stable in portage, so I merged it in. What a mistake! All my existing configuration (including for NoScript+), all my bookmarks, all record of previous visits to site - gone, deleted, vanished. I'm not happy about that. The usability of the program has gone down, down, down. Not a lot seems to work properly, anymore. For example, it used to be that you could mark a selection of "your" cookies then delete them in one operation. Now you have to mark a single cookie and delete it, mark the next cookie and delete it, Even the screen area where the current URL is displayed is now displayed in low-contrast miniscule type, so that I can barely read it. What on earth are the upstream developers thinking about? Destroying somebody's configuration is not a nice thing to do. I've a feeling that all this must have been discussed here quite recently, so apologies if I'm dredging up old stuff. Still, a recommendation as to how I might proceed would be welcome. Should I go back to 31.8.0 and stay there, or would I be better going with some fork of firefox? Has my old config/cookies/... actually been physically destroyed, or is it just being disregarded by 38.1.0? Looking at my ~/.mozilla/firefox doesn't give me much hope. Yours, in anger. -- Alan Mackenzie (Nuremberg, Germany).
[gentoo-user] Resizing a FAT partition?
Hi, I have a SDcard of this layout: Number Start End SizeType File system Flags 1 4194kB 32.0GB 32.0GB primary fat32lba There are about 11 GByte of data on it. The final result should be a SDcard with two partitions. First a FAT32 with about 20GByte and a second with 10GByte (ext4). I took a look at parted and the resize command, which sounds a little cryptic to me: resizepart partition end Change the end position of partition. Note that this does not modify any filesystem present in the partition. One should use resize2f for that purpose. Firstly I want to shrink the first partition and secondly it is a plain FAT32 partition not ext-something. I did not find a "resizefat32" or similiar. What tools do I need? (beside the way to backup the SDcard, reinitialize it, put 2 partitions on it and copy back the stuff.) How can I acchieve what I want? Thank you very much in advance for any help! Best regards, Meino

On a no-multilib 64bit machine FF fails to compile. http://article.gmane.org/gmane.linux.gentoo.user/284455 On two other 64bit and a 32bit machines it builds with no problems and nothing is deleted, or corrupted.

I'm not happy about that. That's a feature ;). Occasional forced cleaning. This happened when I upgraded (I'm on unstable), but I don't have bookmarks nor saved passwords, and my custom config takes ~10 seconds to set up clicking through the menu, so I didn't really care. Backups are good. Putting all of the config and bookmarks in version control would be even better, except Firefox uses a pretty awesome combination of sqlite, JSON, JavaScript, and text for storing configuration and bookmarks, so of course that would be a nightmare. > The usability of the program has gone down, down, down.

The approach when reducing a partition's size is to first reduce the size of the filesystem, to slightly less than the final partition size for safety. Then delete and recreate the partition, with the same starting point. Finally resize the filesystem to fill the new partition. > What tools do I need?

There are definitely tools to do this and I'm surprised parted says it doesn't touch the filesystem in the partition (but that might have been a recent parted change?) Personally, since you're going to play around with the partitions and resizing existing filesystems, you should really have a backup. If you're going to have a backup then the easiest thing to me is to create new partitions and then filesystems and then restore from the backup. However, if you really want to live dangerously, the last gparted boot disc image I used could shrink FAT32 filesystems and partitions. You might want to see if it still can do so. Good luck! Todd

I'm not happy about that. I'm sorry. All I can say is that I have never had anything like that happen to me, and I've been using the ~amd64 versions for a while now (so I'm on 39.0 at the moment). > The usability of the program has gone down, down, down.

Do none of the many cookie manager addons available for Firefox suite your needs?

As always, use whatever suits you. Personally, I'm sticking with Firefox for a variety of reasons, one of them being that Mozilla is one of the few web technology organisations that actually seems to care about user privacy. *Without* resorting to sticking with -- let alone reverting to -- stone age technologies. > Has my old config/cookies/... actually been physically destroyed, or is > it just being disregarded by 38.1.0?

If you were making it larger then it wouldn't matter, but if you are shrinking it, then you want your files to be contiguous and not sprayed all over the partition. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Both partitions and filesystems (including defragging filesystems) operate at the block level. Wear leveling and bad block handling happen "below" the block level. If you gave flash memory data for block n and later tried to read block n and got back something different it would be very broken. Of course physically logical block n might actually be stored in physical block y, but the flash controller (or whatever is responsible for wear leveling and bad block mapping) still needs to know to give back the data from physical block y when it's asked for logical block n.

Its solutions: > https://bugs.gentoo.org/show_bug.cgi?id=555416#c5 Thanks, but I don't see an explicit solution there. Basically, I don't really know what Firefox profiles are. I think that that section of the bug report you wrote is telling me I need to manually edit my ~/.mozilla/firefox/profiles.ini in some fashion. I don't know how to start Firefox in a particular profile. For what it's worth, my 38.1.0 is built with the bindist USE flag set. As far as I am aware, my 31.8.0 was also built with bindist set. I still can't see how to fix this. Would you help me out, please? I don't think 38.1.0 should have been stabilised with this serious problem outstanding. -- Alan Mackenzie (Nuremberg, Germany).

Hi Alan, 1- open with a editor ~/.mozilla/firefox/profiles.ini file. 2- Sample profiles.ini : -- [General] StartWithLastProfile=1 ===> change this line if default value 1. change 1 to 0 [Profile0] Name=default IsRelative=1 Path=igoxrf4f.default Default=1 [Profile1] Name=dev-edition-default IsRelative=1 Path=y2s06zsp.dev-edition-default -- change "StartWithLastProfile=1" line to "StartWithLastProfile=0" 3- restart firefox and that's it.

Thanks. That's done the job! I've got my old settings, etc. back again. -- Alan Mackenzie (Nuremberg, Germany).
