Recent Hebrew Live CD
As part of the Safe Internet Day we'd like to hand out to school kids a live CD with hebrew support built in. Does anyone know if the efforts with the Kinneret live CD, or Hebuntu are being updated? What's our best option today for a LiveCD with a hebrew interface out of the box? Is anyone doing any remastering for a hebrew distro these days?

A Mandriva One edition with Hebrew support (they have several editions with different support for languages) can do Hebrew out of the box, and with minimal extra effort (opening the ISO and changing some settings) will also display Hebrew on all dialogs w/o needing to choose anything. Is anyone doing any remastering for a hebrew distro these days? What's the deadline for this? I can probably do the above changes this week and distribute the ISO. -- Oded ::..

I have had absolutely no trouble sending faxes using a HOT voice line. I used an old Dynamode external fax modem, a USR 56k external fax modem, and when I switched computers to one with only one serial port and a UPS in it, an Intel chipset HAM. All were done from a Linux system running Hylafax. About a year ago I asked around and got the following answers in relation to sending faxes outside of Israel using VoIP lines. None of the people responding that had cable modems were able to do it. HOT technical support told me that it did not work due to the design of their network. Several of the people responding had aDSL lines and were successfull. One sent his faxes to Canada, one to the U.K. and several to U.S. No one ever answered back with exactly who their service provider was. Questions posed to the Hylafax list were answered that it was not likley to work, and no one had ever reported success. I have a Vonage line provided through AmeriFone. AmeriFone customer support said they had questions from customers, but no reports of success. That could mean that there are people doing it and have never said anything, while the customers who asked, never got it to work. Vonage changes the provisioning of the line for fax calls. It's permanent if you have a business contract, they give you a second line for faxes. If you only have voice service, you can switch to fax mode for the call by preceding the number with *99. Experiments using hylafax, several external modems, with and without *99 and I think every possible combination of speed and other parameters failed, so I gave up. I have a 5m/256k cable modem, use a Linux system as a router and tried with nothing else using the line and wondershaper on and off. I also found that my HP combination printer/scanner/fax using two cheap long distance carriers, 017 and 018, failed to the same fax machines I was trying to call. If you have access ANYWHERE to a computer with a modem on a phone line, IMHO the best option is to install a Hylafax server on it. Hylafax has a good network interface and if you really worry about security, you can set up a shell script to scp the file to a temporary location and then use ssh to issue a sendfax command.

You can fax over Voip and there is even a module for Asterisk for this. What you cannot do is fax reliably from a home DSL connection to a Voip PSTN termination. If the network load is high the connection will glitch and the remote fax will drop it after a number of retries. That's why you use a store-and-forward host in between (i.e. an Asterisk PBX running on a host with good bandwidth or directly at the PSTN origination hardware - aka FXO card present in Asterisk lingo). FYI G711 signalling is indistinguishable from PSTN from the end points, excepting in latency (it is even better than telco G711 because telcos use compression and bit stealing for signalling so the connection is not 64kBps clean as the Voip connection is - that's why intercontinental Voip connections often sound cleaner than even Nezeq local calls). Of course you will never fax over iLBC or GSM, only G711 will work. Usually it is best to buy services from a fax specialized company (like eFax). That allows you to do a lot of things for very little money (usually). Sometimes all you need is an IP as you can send G3 fax files directly to the server, and there are toolkits for bulk faxing and such.

[OT] isrAsterisk 2007 - Final Schedule and information
Hi All, I'm happy to announce that all the issues relating to isrAsterisk 2007 had been finalized. Following is the final schedule for the day: 09:00 - 10:30 Asterisk 101: an introduction to Asterisk 10:45 - 11:30 IBM Open Source Strategy 11:45 - 12:30 Asterisk Configuration Templates 12:45 - 13:30 The High Definition VoIP Revolution 13:30 - 14:30 No Lectures 14:45 - 15:30 Case Study - IBM Blade Servers Enable Carrier Grade Asterisk 15:45 - 16:30 The Asterisk Community and the Digium Channel 16:45 - 18:00 Open Source Projects Kick-off Location: IBM Forum, IBM Building, Petach Tikva. Parking is available inside the building (paid parking) and outside of the complex (free parking). Some of you may be asking what does Open Source Projects Kick-Off means, so here is the explanation: Project I: The Asterisk Peace Initiative Project Goal: Build an open platform to enable open conversational paths between Israelis, Palestinians and any other nationality. Project Tech: Asterisk + LAMP + Server Technology (TBD) Project II: The Israeli Open-VoIP Network Project Goal: Build an open platform where Israeli OSS VoIP and OSS Telephony developers can conduct meetings and converse freely. Project Tech: Asterisk + LAMP + Server Technology (TBD) The target of the first meeting, that will be held in the conference, is to first gather the think tanks to design the project outline, and also start the initial development. Once projects outline had been formed, each team will proceed to start the project itself. The development platforms and bandwidth for the projects had already been provisioned, so the only thing missing at this point is your participation. I hope to see all the VoIP/Telephony developers on this list on location. Kind Regards, Nir Simionovich
Re: Working on a FOSS project (was: Finding a linux related job)
Geoff OK - so you have a negative attitude to programming excellence and managers, maybe you just need a vacation. Let me rebut your points one by one on your own ground: 1) The suits have taken over. It's a well documented fact... - So what. The better the company - the higher the standards for programming excellence AND teamwork. Great companies not only have great programmers - they also have great managers. It will hurt you to hear this but Microsoft has a lot of really talented people that write a lot of great software - if you are not sure about this I suggest you read Jim McCarthy's book Dynamics of software development. Having a few really talented developers is not enough to build a $50M/year software company or even a $5M/year software business. 2) I don't know where you get your statistics or your gross generalization that HR decide who gets hired. I worked at Tadiran, Intel and Rad-Bynet and with over 25 small-large firms in the past 5 years on software security open source consulting gigs and I have run into all kinds of people. The HR people do initial screening but don't decide on hiring a programmer - the hiring manager can be a jerk hiring dunces - but in every single well-run company I am familiar with (Intel, Rad, Tadiran...) there were at least 3 interviews and personal initiative such as FOSS projects always counted for a lot. Programming excellence is valued in the good companies but not at the expense of teamwork. Please don't generalize from your negative experiences. The fact that there is a thriving expert consultant market for Linux and Microsoft developers seems to indicate that there are more than a few managers out there who know what they don't know.

You called it all right Talented developers look to hire developers that have a passion. This is what separates a dot-net-john-bryce-graduate programmer from a real programmer. It's not the degree, it's the passion. You would be surprised how few talented developers there really are in the world and especialy here. The problem with finding them is there is a small window when they are hiring. In a start-up the team is put together by word of mouth, long before the company is actually formed. In a medium size company, the suits have taken over and they are not concerned with the passion to do good work, change the world, etc. They are concerned with how many hours you will put in to make them look good. It's not just me as you think, it's a well documented fact. The fact you worked in your spare time on a project (regardless of whether they know what FOSS means) gives you credit in places where developer passion is appreciated - and this is probably where you want to work. Yes, and it would be the kind of people I would hire, if I were hiring, but most managers are not intrested in it. They don't see it as relevant, and they want real work experince. Working on a FOSS project is not real experiemce either. There is often no managment, no goals, no timetables, no money for professional level equipment and tools and so on. Also from a practical level, going out of university means you have zero experience (no, university projects rarely count as experience), so working on a project with other developers, a team leader, a schedule, users - all that is important not only for your own personal development but also to show a potential employer what you can do. Not to mention they can download the source code and see first hand how good you really are. True, but the personel person who is vetting your resume will not download anything and in almost every FOSS project I've seen you can't tell one programmers code from another. After a few months in the wild, people often modify it, and it becomes the product of many hands. Some FOSS projects are even prestigious - the google SOC is well regarded, and working on a high-profile project might impress your potential employer. It might, I don't think it will in most cases. Geoffrey, you seem to have a huge chip on your shoulder - go to a therapist and work it out. Maybe your world consists of nothing but abusive managers and cheating partners who only want to screw you, but fortunately for the rest of us the world is different. Thanks for the advice, but I was writing public domain (the predecessor to FOSS) and commerical operating system code before you were born. You may been lucky in your choices of employers and projects, IMHO you are just naive. You'll learn. As for a chip on anyone's shoulder and needing therapy, I suggest that since you feel the need to denigrate me and my experirence publicly, you are the one who needs it. In 1978 an IBM Systems Enginer brought in a sign to where I worked, which being young and ambitious at the time laughed at: Old age and treachery

If I can save money by putting everything on one single server, and if it works - then what's wrong with it? I don't see any problem with solving domain names recursively while being open to queries from the entire world. And of course no one said that you need to buy more hardware, just run two BIND servers on the same machine, each bound to its own IP address... Of course, if my service was abused and things were not working, that's a different issue. But since it works, I don't see any reason to change the current configuration. I don't agree with your opinion that my current configuration is wrong. How would you even know if your service is abused ? Are you waiting for it to be abused ? What kind of technical (or management) decision is this ? But since you think it's my opinion, let me quote a few other opinions: http://www.zytrax.com/books/dns/ch4/ ... Note: Running any DNS server that does not require to support recursive queries for external users (an Open DNS) is a bad idea. While it may look like a friendly and neighbourly thing to do it carries with it a possible threat from DoS attacks and an increased risk of cache poisoning. The various configurations have been modified to reflect this. ... http://articles.techrepublic.com.com/5100-1035_11-5860968.html http://www.sprintlink.net/faq/dns.html http://net.berkeley.edu/DNS/recursion-detail.shtml ... It is possible to have both authoritative and caching functions running on the same DNS server, and this was typical in the early days of the DNS. More recently it has become a best practice to separate these functions, and IST did this a few years ago. More information on our DNS servers can be found here (http://net.berkeley.edu/DNS/campus.shtml) ... http://cr.yp.to/djbdns/separation.html ... The importance of separating DNS caches from DNS servers DNS caches should always have separate IP addresses from DNS servers. In other words, the IP addresses listed in /etc/resolv.conf should never match any IP addresses listed in NS records. This separation is widely recognized as the right way to run DNS. As stated in the ``DNS and BIND'' book, third edition, ``Securing Your Name Server,'' page 255: Some of your name servers answer nonrecursive queries from other name servers on the Internet, because your name servers appear in NS records delegating your zones to them. ... You should make sure that these servers don't receive any recursive queries (that is, you don't have any resolvers configured to use these servers, and no name servers use them as forwarders). ... Now, I can go on and quote tens of other resources on proper DNS configuration, however, I hope you get the picture. If I wanted I could change the current configuration and use Netvision's name servers to resolve domain names, and my own name server only as an authoritative name server. It wouldn't cost me more money. But would my server perform better? I'm not sure. Doron Shikmoni told me not to use Netvision's servers, and I guess he is right. Doron is right, and you should not point your nameservers to use the NV NSs, basically since every query will go over your link to them, which I assume is not LAN. --Ariel -- Ariel Biener e-mail: [EMAIL PROTECTED] PGP: http://www.tau.ac.il/~ariel/pgp.html = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
