Cateee: October 2006

Saturday, October 28, 2006. Shell: parallel execution with timeouts. From time in time I was looking how to run a command with a timeout (in a shell script). I never put big efford to find the solution, because I always found a easyer (and probably better) workaround. But few days ago, in a discussion in the austing group (POSIX standardization), I found the solution, in an elegant manner, and it permit also to run commands in parallel. In bash and kornshell):. Sleep 60; kill $pid ) &. Links to this post.

Cateee: C99
http://cateee.blogspot.com/2006/10/c99.html
Tuesday, October 17, 2006. Yesterday I was looking for the changes between the ANSI/ISO C (1989) and the new C99 (ISO 1999). The best information are found in: http:/ home.tiscalinet.ch/t wolf/tw/c/c9x changes.htm. Summary of the main changes:. External identifier now are case sensitive and up 31 characters (in old standard a portable program should not rely on case sensitiveness nor to more of 6 chars). Variable argument on macros. From C : /. Declaration and statement can mix,. 64-bit or longer) with LL.

Cateee: Re: "C and multithreading"
http://cateee.blogspot.com/2007/11/re-c-and-multithreading.html
Friday, November 09, 2007. Re: "C and multithreading". On debian planet. I read the C and multithreading. Post of Miriam Ruiz, but I don't agree with some conclusions:. First of all, I don't agree with Linus. C standard doesn't allow such optimizations. One of the driving point of C standard (and thus C) is that compiler should do what a programmer write, without much optimization, i.e. C should remain a low level language. It was iterated also for the principles of new C1X standard. 09 November, 2007 18...

Cateee: ICANN Factsheet on last DNS root server attack
http://cateee.blogspot.com/2007/03/icann-factsheet-on-last-dns-root-server.html
Friday, March 09, 2007. ICANN Factsheet on last DNS root server attack. Published an interesting article about last attack of root servers (6 February 2007): see http:/ www.icann.org/announcements/announcement-08mar07.htm. The paper is not so detailed and technical as one should expect, anyway it is worth to read it. It seems that also the remaining root servers. Should move to anycast. I think this is good, but it will works reliable with TCP? Do someone use TCP to query DNS servers? You need TCP for qu...

Cateee: ntp: keeping the right time
http://cateee.blogspot.com/2006/10/ntp-keeping-right-time.html
Wednesday, October 18, 2006. Ntp: keeping the right time. This is an other topic inspired by ;login:. Magazine). I think it is essential for a computer to have the clock showing the right time, and it is not hard! On my servers I use either ntpd. The daemon), or 4 time per day a ntpdate. To a nearly ntp server. On my home desktop the ntpdate is run at every boot (because it is never on for long time), and on my ibook the same on linux boot and ntpd on MacOS (which is the default). Open source activist, D...

Cateee: About me
http://cateee.blogspot.com/2006/10/about-me.html
Tuesday, October 17, 2006. As first post, I'll describe briefly me and my interest. I'm Swiss, I spoke Italian (mother tongue), French, German and English. Maybe this blog would improve my English skills. Recently with my new laptop (iBook), I use dual boot: MacOS and Linux/Debian. I install nearly every kernel from "vanilla sources" since 2.0.28/2.1.8x. I read kernel mailing list. Since 7-8 years, but I've contributed only with few and small patches. I own a small vineyard, and I make also some wine.
