I'm trying to learn russian since a few weeks. I was looking on the Internet for a Russian-English dictionary with stress on Russian words because this is the only tool I needed to learn spoken russian by myself. I found the eSpeak Project, they worked on a russian dictionary with stress associated to each word. It's great but it's annoying to look for a word in a big text file... That's why I wrote a small django+jquery frontend to query the dictionary easily. Also I don't have russian keyboard so I add a small transliteration tool to the interface.

You can access it here: http://www.biais.org/russian-stress/

EDIT: It doesn't work in IE, Get Firefox

EDIT2: It's now working in IE, anyhow Get Firefox

Note: The dictionary is not perfect but it contains about 220000 entries.

I'm used to run emacs from my shell and my mind is not able to switch from the command emacs to emacs-client when I have an opened windows. This is why I wrote this simple shell script that:

• run emacs (and force server-start) in detached screen with a particular id (emax) if this screen doesn't already exist
• run emacs-client (with the -n option : don't wait for the server to return) else

[shell]
#!/bin/bash

screen -list |grep emax > /dev/null
if [ $? -eq 1 ]; then
	echo "screening -- emacs $@"
	screen -S emax -d -m emacs -f 'server-start' $@
else
	echo "connect to emacs server and detach -- emacs $@"
	emacsclient -n $@
fi

I prefer to get a separate emacs instance when I'm writing mail because I can focus on it. You may want to have special cases for this, use this script instead :

[shell]
#!/bin/bash

# special case for mutt mail edition
if [[ "$1" =~ "/tmp/mutt"  ]]; then
    echo "attached"
    detach=0
else
     echo "detached"
    detach=1
fi

screen -list |grep emax > /dev/null
if [ $? -eq 1 ]; then
    if [ $detach -eq 1 ]; then
	echo "screening -- emacs $@"
	screen -S emax -d -m emacs -f 'server-start' $@
    else
	echo "normal mode -- emacs $@"
	emacs -f 'mail-mode' $@
    fi
else
    if [ $detach -eq 1 ]; then
	echo "connect to emacs server and detach -- emacs $@"
	emacsclient -n $@
    else
	echo "connect to emacs server -- emacs $@"
	emacsclient $@
    fi
fi

Note: I also set a zsh alias to emacs on this script

ack is a grep like for programmers. I'm used to run grep -R and find ... -exec grep to search for something in my code or in others code. But since I found ack, I definitely switched to ack when I code. ack website.

My favourites features:

• Color highlighting of search results
• Searches recursively through directories by default, while ignoring .svn, CVS and other VCS directories
• Many command-line switches are the same as in GNU grep, so the transition is nothing

ack 1.78 is out

A really well explained post about 2 database mistakes

Mistake #1: treating a database as a dumb object store. This is a really popular idea right now- Hibernate does this, as does Ruby on Rails, and a number of other ORM packages take this effective approach. On the other hand, dynamically typed languages are also really popular.

[...]

Mistake #2: file formats (and this includes marshalled data structures), are wire protocols, and need to be designed to be as abstract as possible- to reveal as little about the internal structure of the program as possible (preferrably none at all).

In this blog post, I wanted to test the spammer crawlers. Experience time : 2007-02-08 to 2007-12-18, more than 10 months. Some results:

• 114 Mo of pure spam
• 17443 mails (average: 150 / day during the last 2 months)
• 9498 mails in the ceresistan mailbox (with the mailto: link)
• 7945 mails in the recetansis mailbox (text only)
• 0 mails in others mailbox (fortunately spammers don't use visual captcha breaker today)

A chart of the number of spam (both mailboxes) received per day during the test:

I forgot to test this one:

Since I began to work, I'm trying to follow simple rules to organize myself to do what I have to do. Simple rules, nothing original. I discovered something much more evolved: the Getting Things Done method. I didn't read the GTD bible but I read many blog posts about it and tried GTD online tools. In my personal point of view, it's really too complicated and it creates an important work overload. Then I discovered something really close to my "simple rules" Zen To Done (ZTD). My "simple rules" ( SR ) are:

• The use of a centralized todo list accessible from anywhere, in practice: a wiki page on my website. This centralized todo list is associated with a decentralized (temporary) todos, in practice: a pen and something to write on.
• Focus on what you're doing and do one task at time. I'm, personally, mono-threaded, I can't work on 2 tasks at a time. Before starting on something important, I'm focusing on my need of focus . That's strange, but I just need to think about focusing to focus on my task.
• Write on my decentralized todo what i'm doing when somebody or something interrupts me.
• Take a break when you need it. Focusing is something hard, unfortunately I can't focus on my tasks all day long.

Really, focusing is the most important thing, other rules work to support my memory.

I'm working on a linux box (ubuntu). Sometimes, I work on web design and web development with firefox and firebug but I have to maintain scripts and styles working with Internet Explorer. I used to deal with these solutions:

• Work on Linux, reboot on Windows and debug
• Use a Windows box with VNC
• Virtualize a Windows on my Linux box (unusable because it's too slow on my computer)
• Work on Windows
• Use wine with a complete windows installation

I recently discovered a better solution: ies4linux. It simplifies the configuration of wine and the installation of different versions of IE 5.05, 5.5, 6 and also 7 in their new beta version.

A very interesting article from a FreeBSD kernel developer. Learn what the kernel can do for you (and better than you):

Varnish allocate some virtual memory, it tells the operating system to back this memory with space from a disk file. When it needs to send the object to a client, it simply refers to that piece of virtual memory and leaves the rest to the kernel. [...] Varnish doesn't really try to control what is cached in RAM and what is not, the kernel has code and hardware support to do a good job at that, and it does a good job.

In this blog post, I wanted to test the spammer crawlers. I check the tested mailboxes today:

• The first spam arrived February 8, 2007 at 11:11 in the recetansis mailbox: 13 days after the test begins.
• Second arrived 2 minutes later in the "ceresistan" mailbox.

Today's results, about 20 days after the beginning of the test:

• 7 spams on "recetansis" mailbox.
• 9 spams on "ceresistan" mailbox. The same 7 as in "recetansis" mailbox + 2 originals ;).
• 0 spam in the others boxes

Note: this blog receive about 250 unique visitors per day.

CAPTCHA: (an initialism for "Completely Automated Public Turing test to tell Computers and Humans Apart") is a type of challenge-response test used in computing to determine whether or not the user is human. A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen. CAPTCHAs are used to prevent bots from performing actions which might be used to make a profit on the part of the person running a bot.

There is many project aiming to defeat CAPTCHA using OCR or other AI algorithm: AiCaptcha, Breaking visual CAPTCHA. Some spammers also uses social engineering (manipulate people): solving and creating captchas with free porn.

After reading pwntcha, it's seems really easy to pass through CAPTCHA, but do spam bots really use this kinds of advanced solutions to get email adresses or post comments on blogs ? I didn't find any test on the web. That's why I want to test spam bots that come here. I specially created the following email addresses and I'm hoping spam bots will try to send me emails:

1. email: ceresistan@biais.org
2. email: recetansis@biais.org
3. email:
4. email:
5. email:
6. email:

Note: each address use the same set of characters and aren't in my english dictionnary. All addresses are neither used nor published elsewhere. I also created a "not yet" published address to testify the results. I will post my results when size of mailboxes become significant.

Now, it's time to invoke spam bots. Come on, suck this page, use your regexp, algorithm and send me viagra ads ! I hope to receive a least one mail in the first mailbox
