Testing ads for malware presence is not as simple as testing an executable for a virus because in general case ad is a combination of Flash, JavaScript and HTML documents hosted on 3rd party servers which may change content of these documents at any time. This means the testing machinery have to do repeat tests all the time but given that there are many creatives in ad network there is a limitation on how quickly you can do repeat tests. If malware author is smart and for example implements a strategy where malware is active only on each 100th impression it may take quite long time to detect the problematic ad.
It is not completely true. If you take picture of me the copyright might be yours but you are often limited in what you can do with the picture. Unless I sign a model release form. As I understand according to USA law there are some cases when non-private use is allowed without the signed form but you definitely are not allowed to sell to stock image agencies without this.
I was always wondering what's the point of icons on desktop. The idea is really silly - most of the time desktop is covered with opened windows so you cannot access the icons without closing or minimizing windows. Good to see KDE 4 got rid of them:) Perhaps I should switch back to KDE; systems which not allow to remove all icons from desktop always annoy me a bit. The only time I see empty desktop I'd rather see an abscured background there.
Same story here. We run puppet with more then 400 servers and it is pain to get it working. There are many issues which show up here and there: memory leaks in both client and server (aka puppetmaster), periodic lock ups and even file corruption. Besides it is quite slow. I'd migrate us to something better but not sure what to switch to. Besides we've invested into puppet based infrastructure too much by now to make the switch easy. One problem with puppet is that it looks very nice at first when you have small infrastructure with small number of servers and simple manifests. As your infrastructure grows you hit all scalability issues with puppet but by this time switching from it is hard.
For anyone interested into how to get puppet work for any real work load this is what we do:
Run Puppet under Apache+Mongrel. By default it runs using WEBrick what breaks easily under any moderate load. Plus using Apache you can run multiple backends what helps if you have multi-core server for puppetmaster. Alternatively you can use Nginx+Mongrel or other web server with proxying capabilities + Mongrel.
Restart backends from time to time because they leak memory. We have a cron job to do this every 15 minutes (yes, it is that bad).
Puppetmaster has a cache which we saw to get corrupted sometimes. Our "fix" is to delete it before each restart.
Do not run puppet client as daemon. Run it as a cron job. Puppet client when run as daemon leaks memory and get stuck from time to time. In our cron job we add random sleep before starting client to make sure requests do not hit server at the same time.
Never serve big files over puppet (i.e. from its filestore). Puppet does a number of stupid things with big files like say reading them into memory first before serving it to puppet client. If you need to distribute big files use other means (HTTP, FTP, NFS, etc).
Suddenly, the foundation and moral code they've all built their life on - is provably false. And therefore...gone. They would go nuts.
Not going to happen. Your assume that these people would logically conclude that their believes are invalidated by the fact that aliens exist. But there is a flaw in your reasoning: you expect critical thinking from people who have never had it. There is already enough facts discovered by humanity to prove that all religions is bullshit yet somehow all religions continue to exist just fine.
As I understand Christian is basically person believing that Bible is true. But if Bible is just a collection of fair tales then what's the point? This is what I don't get about people who say they are Christian and who say they believe in God but at the same time say that you shouldn't take Bible literally. What exactly you believe in then?
Bible as book about ethics? Have you really read it? It contradicts itself all the time. You can use Bible to justify anything: one time it is take eye for eye, other time you should turn other cheek for slap.
intellectual? democratically? elected? socialist? You must be joking. He is power hungry ex-KGB who wants to be a tsar of this country. Corruption is on rise. Freedom of press is supressed. TV is under total control of Putin. Chechnya is still in mess. Russian economy is still alive only thanks to inflated oil prices. Should I continue?
It is not about tunning and it is not about journaled file system. It is about reiserfs being designed to do better work with filesystems having a lot of small files (what squid cache actually is). It is just better then ext2 for this task.
There is much more in BitKeeper but its main and quite unique fiture is that it is built around model of distributed repositories. With CVS you have only one central repository but in BitKeeper you can have as many as you want and it is able to merge code from each other and it does it very intelegently. I think it is the main reason why Linus chosed BitKeeper over any other version control system.
Anecdotical evidence you may want unique IP for your mobile: when last time I tried to register an ICQ account while connecting my computer to internet using GPRS connection on my cell phone I wasn't able to do it. ICQ server were rejecting me because of too many registration attempts from my IP (which is shared between other users).
I think you are comparing apples with oranges. SPECweb99_SSL is a benchmark that shows limit on a number of simultaneous connections for web server with SSL. Terry Lambert's tests are much simplier.
This faq entry is a bit outdated. There is experimental extended regexp syntax which allows to match balanced expressions. There is even an example in perlre (look for documentation on (??{ code }) syntax construct).
Also there exist CPAN module Text::Balanced which does balanced expressions matching.
Yep, this problem is real. One of Perl gurus had to quit open source community because of restrictions imposed upon him by his employer. This story was covered by Slashdot in the past.
Huh? Moderated as Interesting? It is highly ignorant. Have you ever tried to learn foreign languages yourself?
As a person who is not English native I can say that it is simply not true. Learning foreign languages beyound simple "How are you? Thanks, I'm fine" requires noticable effort and for most people who have no special talent for learning languages means spending a lot of time and/or money on studying. This is the barrier.
But mod_php is installed so often, because PHP is so popular
mod_php is installed so often because it is easier and cheaper for ISPs. The problem with mod_perl is that it is too powerfull and it lets programmer to have nearly full control over Apache server. In ISP environment such power is bad thing as it becomes impossible to share one Apache server between several independant hosters. In short to provide mod_perl hosting ISP have to give each its customer dedicated Apache server. Obviously for ISP it means that they spend more time/money on system administration and that resource requirements (mostly RAM) are higher.
My point was just that bugzilla is hardly "the best world bug tracking system". Thats all. I'm not suggesting that RT is the best (though sometime ago I did review of all opensource Perl bug tracking systems and I found RT to be the best).

For example theory of evolution contradicts Bible and I guess majority of other religions.

There is already enough facts discovered by humanity to prove that all religions is bullshit yet somehow all religions continue to exist just fine.
And as opposed to the Koran, christians (in generall) do not belive that God has written the bible (or dictated it).
I bet you'd be put on fire as heretic for these words in older times.

It is not that painless. We usually do in our db migration scripts:
Works well for any table definition changes. Doesn't require taking the DB offline. Doesn't change order of columns unless you want it.

I suspect it would be much more easier to use real web browser to run tests than emulating it with Javascript.pm.
Take a look on Web Site Test Tools and Site Management Tools page. And of course shameless plug: HTTP-WebTest. If you will check the latest make sure to try it's beta version.
