Hi, Hrm, I really don't think so, but anything is possible. It is a Windows 7 under VirtualBox - but I am 99% sure, I didn't ask for this, nor does VirtualBox have anything on Grub4dos in its product docs. But after Googling, it appears that it is somehow related to VirtualBox, I wonder why VirtualBox's internal docs don't talk about it. My humble mistake.

Re: Hebrew calendar software creators: can you notify this list when updating the calendar?
you can generate the list automatically using some scripting language , e.g. python: on debian: # apt-get install libhdate-python # import hdate year = 2010 h = hdate.Hdate() h.set_gdate(1,1,2010) julian = h.get_julian() for i in range(0,365): h.set_jd(julian) julian += 1 day = h.get_gday() month = h.get_gmonth() holyday = h.get_holyday_string(1) if holyday: print "%02d/%02d* %s" % (day, month, holyday) #--- 2010/4/14 Shachar Shemesh : > Dotan Cohen wrote: > > It looks like it would need to be hand edited > > > > Watch your language! > > Shachar > > > -- > Shachar Shemesh > Lingnu Open Source Consulting Ltd. > http://www.lingnu.com > > ___ > Linux-il mailing list > Linux-il@cs.huji.ac.il > http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il > > ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Even if the usability is limited, it still is. If/when they expand the usability of the other files, it would be easier to expand the usability of calendar.judaic if its initially there. 2. I think 2 things should be done about including an up to date calendar.judaic file in the distributions: 2.1 send a bug report with an up to date version. 2.2 send a bug report that include the script for generating an up to date version. Hopefully, the maintainers will have the script run automatically each time they need an up to date file, so that an outsider intervention, such as ours, can be minimal. In addition, with a well documented process of generating the file, it would be easier for any one to create an up to date version and file a bug for its inclusion. 3. Is there a way to semi automatically create the non regular dates, such as the postponed date of the holocaust day? Is there a known authoritative sites to pick these dates from? _ Hotmail: דואר אלקטרוני מהימן עם הגנה רבת עוצמה מפני הודעות זבל. https://signup.live.com/signup.aspx?id=60969 ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Hello list, I have a small help to ask you, that I've wrote about it at: http://whatsup.org.il/forum/53484 (Hebrew). To make things short, I've created a patch to support BiDi on Lazarus implementation in GTK2. In order to apply the patch, they want to make sure that the two binding functions I've added supported in all current major Linux distro's. I wish to find out, what is the earliest version of libpango and the earliest distro version that have the support of the following functions: pango_unichar_direction pango_find_base_dir I will appreciate any help on this matter, Thanks, Ido http://ik.homelinux.org/ ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

there are some fully automated ways :-) :
I. the command line hdate:
hdate -H 2010
will print all the holidays for the year 2010
II. a python/perl script using libhdate will generate a list of holidays:
an example of such a python script is attached in earlier post in this
discussion. here is a perl example:
# apt-get install libhdate-perl
#---
use hdate;
$h = hdatec::new_Hdate();
hdatec::Hdate_set_gdate($h,1,1,2010);
$julian = hdatec::Hdate_get_julian($h);
for($i = 0; $i < 365; $i++) {
hdatec::Hdate_set_jd($h, $julian + $i);
$day = hdatec::Hdate_get_gday($h);
$month = hdatec::Hdate_get_gmonth($h);
$holyday = hdatec::Hdate_get_holyday_string($h, 1);
if ($holyday) {
print $day . "/" . $month . " " . $holyday . "\n";
}
}

A good example is Shared Storage ] * Quality Hardware (I personally prefer HP - continuing the line of Compaq from the past) * Reliable OS! Can't stress this enough. Of course, reading this on linux-il - you've already made the right choice ;) Also remember that your hardware and software are not alone in the game. A website needs to be connected to the Internet. Even if you hardware and software are up 24/7/365 - if your switch/router/network connection dies for some reason, the web site will still be down, as far as the customers care. So you need multiple network connections from multiple ISPs on your own IP netblock that you can advertise to all the links that are currently up :-) HTH, -- Shimi ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Seconding Shimi's reply - a single hardware server is a major single point of failure. You need at least two of each (even routers and uplinks if you can afford it, let alone network interfaces and redundant shared storage et al. so not even the backplane of the SAN box or the network interface is a SPoF). Putting the front end in a virtual server adds to its isolation from the rest of the system since it is more likely to be the target for an attack, but it won't help high availability one bit. The tools are not overly complicated - just take: 1. a couple of towers or rack-mounts with hardware you rely on 2. RAID 1+0 disks 3. at least two network cards for each address, bonded 4. if possible then redundant routers, you can achieve this with linux servers but we just opted for hardware. 5. If you need shared storage then you can build a SAN box with linux+DRBD+iSCSI if you don't want the hardware option. 6. Put an LVS load balancer in front of the front-ends, you can even run them primary-primary with multiple public addresses. "fake" for internal "floating" ip address if you need it. DRBD and linux-ha or mysql/postgresql replication for database redundancy. --Amos ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Re: High Availability
A number of issues: First - what. You need to replicate (a) links, (b) storage, (c) service machines. Links are internal and external. Multipath internet connexions. Multipath LAN connexions. Multipath storage links. Redund network infrastructure (switches, routers, firewalls, IDS/IPS). Replicate storage. If you use SAN with dedicated links, multipath links and storage. Redund storage hardware and add storage replication. Add auto-promotion, takeover, and (if possible) partition prevention mechanisms. Use STONITH. Service machines are the easiest to replicte. Simple heartbeat will provide a significant level of failover and/or failback. Here, likewise, use STONITH or other partition prevention mechanisms. Under-utilize. 70% duty cycle is good. Expect costing hikes. M ---MAV Marc.
