Hebrew stemming
Hi all, Does anybody know of a stemming library for Hebrew? Google can find several discussions on it, but I could not figure out if something came out of it yet or not. What other things one should consider when looking at a Hebrew search module? It seems that Google does very basic stemming + partial words match. Is there some form of public work on the subject?

data security
hi one day this week, i started my computer, it behaved very strange - i had a blank screen for about 2 minutes before i got the boot screen, then it continued to boot from ... network the reason was that the hard drive has died. it wasn't even recognized by the bios. the computer was 2 months old, so i replaced the hard drive. when a hard drive dies and it is under warrenty, we need give the old one when we want it replaced. usuallyon the hard drive we have some personal things - pictures, documents, or confidential data if it belonged to a company etc... assuming the data is backed up (backing-up is an issue for another thread), we are left with the possibility of someone retriving data from the damaged drive. and when the drive is damaged, we can't even access it to erase that info before replacing it with a new one. so i though of a solution - use a crypto FS. but there are many problems with it. the practical problems are at least: 1. i do not know of a major linux distibution (i.e. redhat/ubuntu etc... ) that fully support crypto-fs out of the box, so if i use it, i will need to do manual changes every time i upgrade the system. 2. it is not really secured if the key is stored on disk. however if the key is not stored on disk, then the computer can not acces the data without human intervention, which is not good either when it comes to servers. and guys/girls, take my advice and back-up your data every short while. everybody thinks it will not happen to him. but it does. it is just a matter of time. erez. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

And so does Ubuntu. 2. it is not really secured if the key is stored on disk. however if the key is not stored on disk, then the computer can not acces the data without human intervention, which is not good either when it comes to servers. What I do is to not encrypt everything (which is a good idea anyways). The root file system and all of the service directories are not encrypted, and only the data is. I also tweak the Debian startup sequence to not ask me for the encryption password during boot. This way, the system boots without a password (but does not contain any data), and I use a small script to perform the actual crypted file system mount later (by which time I can log into the machine from ssh). I didn't bother to use it yet (not quite relevant for my desktops) but I think current Ubuntu (8.10) also offers to encrypt only your home directory - so part of your login procedure is to provide the key to mount just the home directory of the particular user. That way you get the PC up, you don't get a performance hit from encryption of data you actually don't need to hide, your data is safe until you login (and then I think it's still accessible only to you), multiple users can share the computer, each with their own key. All this is implied from installing Ubuntu from scratch on my work desktop last week (finally switched from Debian). No actual experience (yet).

HOT ISP (Was: Orange as a landline ISP)
Right now I have a HOT modem and Netvision, which when it works... It also happens to be down as I write this and has been for almost 6 hours. I just left HOT after four years of suffering their constant outages (I had both internet and VOIP telephone). I went to, of all places, Bezeq and I've discovered that Bezeq has improved in the past few years. It is a few (less than ten) shekles more expensive, but so far the service had been terrific and they even included for me a 4-port wireless router built into the modem. I should also mention that the tech who came to my house has been a Bezeq tech for 14 years. It showed in the way he worked. HOT techs always look like they just graduated from Yossi's Technical Garden and when I ask them, they are usually in the field for less than a year. I understand that HOT is new and growing, but they just don't yet have the experience that Bezeq has. -- Dotan Cohen http://what-is-what.com http://gibberish.co.il א-ב-ג-ד-ה-ו-ז-ח-ט-י-ך-כ-ל-ם-מ-ן-נ-ס-ע-ף-פ-ץ-צ-ק-ר-ש-ת ا-ب-ت-ث-ج-ح-خ-د-ذ-ر-ز-س-ش-ص-ض-ط-ظ-ع-غ-ف-ق-ك-ل-م-ن-ه-و-ي А-Б-В-Г-Д-Е-Ё-Ж-З-И-Й-К-Л-М-Н-О-П-Р-С-Т-У-Ф-Х-Ц-Ч-Ш-Щ-Ъ-Ы-Ь-Э-Ю-Я а-б-в-г-д-е-ё-ж-з-и-й-к-л-м-н-о-п-р-с-т-у-ф-х-ц-ч-ш-щ-ъ-ы-ь-э-ю-я ä-ö-ü-ß-Ä-Ö-Ü ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

On the other hand, if you go that way, my neighbour who just went the internet way with bezeq and is over 70 has a terrible experience with them. i spent half an hour to convince the guy over the phone that the fact that the modem disconnects from bezeq every few minutes is not related to the fact that they forced her to connect to it wirelessly for some reason. They also sent half way across Haifa to replace it (not sure if she actually did it yet), when she travels by bus and we actually leave outside Haifa and 1.5km from the nearest bus station ... Hot, although the service quality is a bit shitty sent a tech over to my house about 5 times and replaced the modem at my house twice due to connection problems. they are all worthless, it mostly depends on what exactly you need from the at the time. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Bogofilter on a shared folder
Hi, We have a few shared folders in our Cyrus mail server. These shared folders do not have a real user behind them, rather more than one opens them (via Other Users option). As such no one filters their incoming emails for spam. Some background our setup, we use: 1) Postfix for SMTP 2) Procmail for processing of emails 3) Cyrus for IMAP (mail storage) I wondered if anyone has setup something of this sorts - I couldn't find a distinctive guide on the Internet on how to do it: 1) Bogofilter any incoming mail to this folder 2) Allow training (ham and spam) of this bogofilter via two folders that will include spam emails - or via forwarding as an attachment to two email addresses - whichever is better for bogofilter - I am not sure which Thank you for the attention. -- Noam Rathaus CTO no...@beyondsecurity.com http://www.beyondsecurity.com Know that you are safe.

It may also be that the DOK does not work properly with the computer, I have had that problem, but that was a long time ago. Make sure it is directly connected to the computer, I have had trouble using a hub when booting from a DOK. I did a quick web search and found: http://www.cs.cmu.edu/~dpelleg/X31_freebsd.html For the purposes of installing, I think it is safe to assume it works the same with Linux as FreeBSD.
