If people knew the grep, sed and vim tools, millions of useful software products would have been never developped.
I’ve just noticed that it’d be good to change the string new test_suite to more stable macros BOOST_TEST_SUITE. A very simple command did everything for me after spending 5 minutes for this:
[sakhnik@incognito ~/work/mps]$ find . -name '*.cc' | \
xargs sed -i '1,$s/(new test_suite(\([^)]*\)))/ = BOOST_TEST_SUITE(\1)/g'That’s exciting!
Слухаю — і ніяк не можу наслухатися, просто заворожуючий звук. Може, моя мама мені так само співала? Це те, за що я так люблю цю культуру!
Гойда-гойда-гой, ніченька іде,
Діточок малих спатоньки кладе.
Під вікном тремтить вишенька мала,
В хатку проситься, бо прийшла зима.
Гойда-гойда-гой, очка заплющи,
В сні щасливому зігрієшся ти.
Йди до хлопчика, люба вишенько
В колисочці буде тепленько.
Гойда-гойда-гой ніч прийшла до нас,
Діточкам малим спатоньки вже час.
Рости, хлопчику, з вишенькою враз,
Хай не скупиться доленька для вас

Do you recognize this brilliant face? It looks like there’s no limit for ukrainian pirates.
I’ve noticed that there’s a way of depicting stress signs in Cyrillic text, like the following: КМІТЛИ́ВИЙ, ТЯМУ́ЩИЙ, МЕТИКО́ВАНИЙ, МЕТИКУВА́ТИЙ, ПОКМІ́ТЛИВИЙ, ШТУДЕ́РНИЙ. I don’t know how they were typed. But analysis revealed that they refer to so-called composed utf-8 characters. On the way of the investigation it appeared that the XOrg allows to define a custom composition key to type complicated characters easily.
There follow few examples below:
<rctrl>=e ⇒ € |
<rctrl>--- ⇒ — |
<rctrl>'e ⇒ é |
<rctrl>~n ⇒ ñ |
Nice! So I know how to type diacrytic characters in any graphical application. Additionally, to the graphical stress sign is one of composed unicode characters, it can be inserted into an XML by its code: ́. There’re many other composing characters, which can do interesting things: w̳o̸rld.
Always mixed up accents in foreign words, and it was difficult to find wrong spellings in the StarDict. So I googled the problem.
It appeared that the unix-way is to rely the comparison during sorting on the current locale. Besides the StarDict allows a user to set any language-specific collate function:
I’ve chosen the utf_unicode_ci, and now I’m astonished with the result:
Where’re those known from the university times core dumps on Linux? How can I discover a really rear bug in the server daemon?
Well, it appeared that they’re just turned off for ordinary users in the /etc/profile:
# No core files by default ulimit -S -c 0 > /dev/null 2>&1
Really, why a user should know about such a weird thing? Now I always reset the ulimit before starting an application being debugged.
Finally I’ve given up the LA style. The main reason is that I like much more the casino, which is more authentic. The small one is that I’ve got annoyed by its complexity and pretence. That was a hard step after a year of intensive study.
I always wandered how difficult would it be to use wireless network on my linux box. But all the complexity reduced to installing proper driver for the on-board
[~]$ /sbin/lspci | grep Wireless 08:04.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
From the web it appeared to be the native bcmwl5 guided by the ndiswrapper.
Almost there! The GNOME’s NetworkManager applet showed available wired and wireless networks to be chosen.
At last I visited my friends yesterday. It seemed that we never parted.
Here’s Dima taking off:
And this is Tonya:
That’s appeared to be nice!
I’ve given my old laptop to the parents, having told them not to reinstall the system. I wanted they learn working with an open source system (linux). But a problem appeared: how to maintain the system? The only connection to the internet is a dial-up GPRS one.
Well, actually this is no more a problem. Let suppose my father establishes a connection to the internet, then connects to the well-defined server, which we both have SSH access to:
[smm@home ~] ssh -R 1234:localhost:22 koresha@koresha.org
Thus, any connection to the port 1234 will be forwarded to the home:22. So, now it’s my turn:
[koresha@koresha.org ~] ssh -p 1234 root@localhost
And that’s it! I have the desired root console remotely.
I’ve been using the ObexFTP by today. But it appeared that this is much more easier.
There’s a VFS plugin, which enables native browsing and handling experience of data. So I just open the url obex:/// in any of nautilus applications, and vois-là! This is really cool, because I don’t need additional software or sophisticated bools.
Finally, I’ve succeeded installing the gnash to play Adobe flash videos. It took me three times of recompiling it with different options to support ffmpeg. Actually, the out-of-the-box version doesn’t support playing YouTube movies, and the hint was found on pages of the Wikipedia.
Thus, when I’m able to watch videos from YouTube, I’ve tried myself to upload one. Enjoy!
A year has passed quickly, and I celebrate my first anniversary of salsa LA study.
I’ve understood how not to spend much time updating my software. There’re packet managers, which work in my Fedora 7 just well. So I’ve stopped compiling software from sources.
But they don’t updated the Vim as quickly as I want. So recently I set up the aap build system. And now to update my Vim I just type:
$ aap update; sudo aap install
And that’s it! It’s fascinating, isn’t it?
I believe that compilers must do much work for me, that’s why I prefer metaprogramming techniques. Boost::spirit, boost::mpl make my code very resource demanding during the compilation process. But it’s worth indeed.
To make builds faster, I’ve just installed and set up so called distcc — the distributed C/C++ compiler. The result is just exciting!
To use the compiler with the boost build system, I just modified a line in the user-config.jam:
using gcc : : distcc g++ ;
Thats all I’ve done to get ten times faster build!
If you think you’re a looser (an average man, bad student etc), you’re indeed.

The same story repeated, I discovered that I can’t just calmly listen to the argentine tango music. But I used to earlier! The same story, like with the salsa music!
When I hear their melody, rhytm or whatever else, warm and exciting emotions come to my head, and fill out all my mind. There’s the only desire after that: to dance one more time again.
Many things happened during the last month. I’ve been quite busy on the job, participated in an international salsa congress “Salsa mayovka”, opened the bike season after the winter break etc.
There appeared a task to encode a binary data to base64 and then decode it back. There’re many solutions, but this one I liked very much.
#include "boost/archive/iterators/base64_from_binary.hpp"
#include "boost/archive/iterators/binary_from_base64.hpp"
#include "boost/archive/iterators/transform_width.hpp"
#include <string>
#include <iostream>
using namespace std;
using namespace boost::archive::iterators;
typedef
base64_from_binary<
transform_width<string::const_iterator, 6, 8>
> base64_t;
typedef
transform_width<
binary_from_base64<string::const_iterator>, 8, 6
> binary_t;
int main()
{
string str("Hello, world!");
cout << str << endl;
string enc(base64_t(str.begin()), base64_t(str.end()));
cout << enc << endl;
string dec(binary_t(enc.begin()), binary_t(enc.end()));
cout << dec << endl;
return 0;
}It’s simple enough, isn’t it? But the world is not ideal, and because of a bug decoding doesn’t work, as expected. Fortunately, the bug can be worked around with a little hack.
The short animation “Golden gate” came to my mind, when I saw an unsecured door in a supermarket today. Really amazing! How haven’t I noticed it yet?
It happend indeed! The other day I visited the first in my life tango milonga. After three unsuccessful attempts.
Well, I’m astonished, not deeply impressed. But I think I’ll like them in the nearest future. The music of good quality is not loud, one can just seat and have chat with others.
I felt that dancing on milongas would give me a masterfulnes and some certainty that I’m doing well, that my experience is portable indeed. It’s not an assumtion, it’s a fact!

I really like my new job! I’m free to choose technologies and tools to use, I can decide what’s right and what’s wrong on my own. It’s really amazing!
Because of my bosses being abroad, no one stays behind my back and watches what I’m doing. Probably they can do this by means of remote desktop, but do they need to?
The only awful thing is inevitable: I want to sleep, just fall down asleep and don’t wake up only until I feel strong and fresh enough again.
Only clever head allows itself to carry a modest hair-cut. One should diverge by his intelligence!
I’ve just added ability to send me feedbacks about typos or other orthographical errors. Just select erroneous text with mouse pointer and press Ctrl+Enter. Thank you in advance!
I always disliked HTML because of its oddities. To post previous table I tried three times to mark it up. Then I gave up, and switched to the thing I really know, that’s DocBook XML.
First, the posts have very clean logic structure, there’s no mixture of content and representation.
Second, all sources of my posts can be stored in my repository now. That has promising advantages for the future.
My next goal is to find an offline blogger client, probably a plugin for the vim, so that I could avoid using html forms and automate the process of posting.
It was always complicated to type some beautiful text characters, for instance quotation marks ‘’ or “”. Actually, I’ve never known how to do it efficiently enough. When I worked under windows, I pressed the alt key then typed four-digit code of the character, and finally released the alt. That was six–seven keys to press!
There was no such possibility under Linux at all. So I tried to use the OpenOffice.org writer first. After years of software development I decided that there’s no better editor than the Vim. So I started using it everywhere. To edit a text in a web input field, I use the ViewSourceWith add-on for Mozilla. To type an exotic sign ’, I pressed <c-v>u2019. That was another seven keys.
And finally I discovered so called digraphs. This beast can help to type almost any character by pressing only four keys. For example, the same apostroph ’ can be typed as <c-k>'9. Moreover, two-character abbreviation of a sign is very easy to remember:
| '6, '9 | ‘, ’ | Digits 6 and 9 are very like the sign itself. |
| "6, "9 | “, ”w | The same story as above. |
| -N, -M | –, — | En and em dashes respectively. |
| N0 | № | Numero, number. |
I haven’t found the ellipsis …, so I had to define it manually in my .vimrc:
:digraph 3_ 8230.
Yes, it’s very easy, every kyiv man knows it’s nesessary to call 09 and to ask a phone girl. So did I when I took on the bus:
—Would you please tell me where is a military store?
—Which street is it situated on?
—I’d like you to tell me that.
—Sorry, I can’t help you...
But because I was speaking loudly enough, two passengers turned to me and prompted politely exactly what I wanted. Next time I shan't call the 09 at all, I’d rather just ask people around me.
The winter has come to us at last. So I prepared my nordic ski, and just tried out the snow coat.
After long summer season, I've lost knack, and it took me near an hour to wash out the previous season klister (it'd be much more better if I did this in the previous year!), and to apply new ski wax. But I was endowed for my effort with very smooth skiing experience.
A small distance (but enough for the first time) showed out that my skiing skills and power remain on the good level, so I'm going to more interesting hillycountry tomorrow.
