Раскладка с елочками

Thursday, May 3rd, 2007

Иногда жутко надоедает лазить в Таблицу символов и нажимать на Ctrl-C Ctrl-V по два раза на слово, чтобы вставлять типографически правильные и идеологически верные «елочки» и „лапки“. Недавно нашел линк на решение в двач /д/. Выглядит это так:

для винды (решение Ильи Бирмана — исторически первое, от него и схема раскладки)
для богоугодных иксов (решение Сергея Столярова)
для […]

Manual modesetting for xf86-video-intel

Wednesday, April 25th, 2007

The new x86-video-intel-2.0.0 driver (known in Gentoo as xf86-video-i810-2.0.0) does automatic modesetting: instead of relying on the video BIOS for a list of resolutions your laptop’s screen supports (which is always the wrong list on modern machines), the new driver reads the information directly from the monitor using DDC over i2c. Which is in theory […]

Apples

Thursday, February 22nd, 2007

So, a certain Sergei Lunin decided to demonstrate his Illustrator skills. So he drew some apples. By hand. With pure vector graphics. Proof here.
I am awed, astounded, speechless. The dude is a vector god.

Goodbye Zaurus

Tuesday, January 16th, 2007

Looks like the Sharp Zaurus line has been terminated. From Open Embedded forums:
yes, we have to confirm that Sharp pulled the plug out
of the Zaurus line.
No successor model is planned, and the end of production
will be early February.
For sure we’ll continue with support, service and accessories
for the Zauri. Also there’re interesting other products around,
so the […]

Dell PA-12 AC adaptor

Monday, January 15th, 2007

My Inspiron 6000’s 65-watt “PA-12 family” AC adaptor died last week, after only 16 months of service. Its passing was not entirely unexpected; since about mid-December, it had become increasingly unreliable, sometimes requiring me to repeatedly plug and unplug it before beginning to charge. And the fact that it gets only 2 out of 5 […]

Random links of the hour

Wednesday, December 13th, 2006

First, an interesting article from the Telegraph, dating from back in May, which I’ve only read recently. Apparently, the United States had ordered some $400 million of weapons and ammunition from Russia (!) to equip Hamid Karzai’s army:
Pentagon chiefs have asked arms suppliers for a quote on a vast amount of ordnance, including more than […]

Best description of the 8800GTX I’ve seen yet

Thursday, November 9th, 2006

Read this. Laugh. (And on a more serious note, Hannibal has an interesting article on the G80 architecture. Basically, it’s not a GPU, it’s a Cell on steroids. The Cell has 8 SPUs; the G80 has 128. I wonder if someone could get Linux’s spufs working on the 8800… If Nvidia ever releases a version […]

Upgrading to apache-2.2

Monday, October 30th, 2006

So I run apt-get dist-upgrade, download a new version of apache, and suddenly going to http://www.tetromino.net/blog/ gives a 404 error. On closer examination, it seems that the new version of apache2.conf that came with the update does not have a DirectoryIndex directive, and as a result apache isn’t autoloading my blog’s index.php. Gotta tell you, […]

Stealing browser history

Friday, August 25th, 2006

Jeremiah Grossman has posted a fascinating demonstration for how a website could find out which other websites a particular visitor has viewed. (If you don’t see it: look at “I know where you’ve been” section on the sidebar. Recognize any pages you’ve visited recently?)
The way it works is brilliantly simple. Suppose you want to check […]

Dr Dave says there is a sploit for Wordpress out there

Thursday, July 27th, 2006

According to Dr Dave, the celebrated creator of Spam Karma, there is a serious vulnerability in current versions of Wordpress. He says that to be safe, you should make sure that Options -> General -> Anyone can register is unchecked. My feeling is that this has something to do with the upcoming Wordpress 2.0.4 release, […]

Wikispam

Thursday, July 27th, 2006

So today I was editing a page in wiki I like, and noticed the following in the code:
<div style=”display:none”>
[We are delicate. We do not delete your content.]
[l_sp25]
twenty links to Polish scammer websites
</div>
How amusing. Are you supposed to be grateful for the fact that this particular Polish spammer didn’t vandalize your wiki?
And on a less amuzing […]

Squid 2.6 in accelerator mode

Thursday, July 27th, 2006

I run Squid in accelerator mode — i.e. all http requests go through a Squid cache before being forwarded to Apache. This noticeably speeds up Wordpress on my puny virtual server. So today apt-get told me that a new version of Squid was out, and I blissfully upgraded from 2.5 to 2.6. An hour later […]

Random links of the hour

Sunday, July 2nd, 2006

The Supreme Court has ruled that the Guantanamo Bay military tribunals are unconstitutional. Interestingly, the court decided that even though the military commissions violated the Geneva Conventions and the US Code of Military Justice, they were not illegal per se; what was illegal was the fact that Bush set them up by executive order, without […]

Not quite what they were expecting

Monday, April 3rd, 2006

Chevrolet is releasing a new model of its Tahoe SUV, and as part of the publicity campaign, allowed all website visitors to put together a Chevy Tahoe ad by combining several clips of stock footage with custom text. Needless to say, the results weren’t quite what they were expecting. My favorite is this gem. I […]

Sveasoft, OpenWRT, and the GPL

Wednesday, March 29th, 2006

First, a bit of historical background. Some years ago, Linksys released the WRT54G home wireless router. It turned out that the router came with an embedded version of Linux, and therefore under terms of the GPL, users of the router were entitled to see the source code. After a bit of prodding, Linksys made the […]

i810 driver news

Thursday, March 2nd, 2006

The X.org i810 driver for Intel “Extreme” graphics cards is probably the premier example of a fully open-source 2D/3D graphics driver. (Despite the name “i810“, the driver actually supports all 800 and 900 series Intel graphics). My laptop comes with Intel 915GM integrated graphics, so I have been using the i810 driver for over 6 […]

Qt4 + Glib = awesome

Saturday, February 25th, 2006

Brad Hards Brad Hughes* of Trolltech says that future versions of Qt4 (perhaps as soon as Qt4.2) will start using the Glib event dispatch loop. This is downright wonderful news for a couple of reasons. The technical reason is that you will be able to use binary Qt4 plugins in Glib/Gtk apps and vice versa […]

How to shuffle cards

Friday, February 17th, 2006

Just read a classic 1999 paper, How We Learned to Cheat at Online Poker: A Study in Software Security by Arkin, Hill, et al. The security researchers found horrible weaknesses in the algorithm that an online poker site used to shuffle cards. Basically, just by looking at their own hand and the first 3 cards […]

How to use Photoshop

Friday, February 17th, 2006

I am greatly annoyed by people who for some reason feel the need to buy or pirate Adobe Photoshop, a $600 piece of software, even though they have no clue how to use it — it’s as if they feel that the hallowed Adobe trademark residing on their hard drive will somehow automagically make their […]

German court says forum admins must manually approve comments

Monday, December 12th, 2005

Many websites allow visitors to write posts and leave comments. Sometimes the visitors are assholes, and leave comments that are (in the relevant jurisdiction) illegal speech — warez, libels, plans for a terrorist attack, that sort of thing. At which point someone (typically a company that is losing money due to the forum post) will […]
