Like a previous poster, I recommend The Grinder. I looked all around for a load testing tool. People usually recommend the Microsoft tool, but I don't do Microsoft. I tried JMeter and a bunch of other tools, but they never feel quite right. Most tools fall in two categories: either completly unscriptable or so scriptable that using a general-purpose script language would be faster.
Among (many) other things, The Grinder has a built-in proxy that allows it to record a browsing session and play it back later. Basically, you start the proxy, set your browser to use this proxy, browse your website, and get back a log of your actions complete with timings and POST values. One other cool features is that it let you define your own datasources so you can fill POSTs and GETs with custom data. Last but not least the author of the tool will personally answer your questions, albeit slowly.
We have a HP5 at work (can't remember the exact model). The header page shows that this printer already printed 1.2 million pages, probabl and should hit the 2 million page mark sometimes next Spring. What do we do? It's a computer science research lab. People here invent tomorrow's computer systems (well at least a little bit), but our office is still full of paper. So much for the paperless office...
Could you point me to a reference that would confirm this? Cause I've met numerous people claiming that StarOffice was written in Java because it included a JRE (true) and was slow (false). Completly bogus of course.
This is a good point, but there is a catch: in this area (printing, file dialogs, fonts...) , the Java APIs are really really bad. Everybody knows that FileDialog is broken. Printing in Java is extremely hard... So OK they could do that, but I think that a native port of those features would take less time.
First I'd like to say that I like Java very much, but I think that this must be a mistake. Let's see. OS X is unix-based, and does support X11. StarOffice (and OpenOffice) runs just fine on X11. Basically their problem is to port the GUI from X11 to Quartz Porting StarOffice (once the biggest open source project) to Java would be an absolutly huge task. This rules out a full port. It leaves the option of using Java as the GUI. World+dog (including me) agree that Java's GUI is so-so, even if it is better on OS X than anywhere else. Anyway, what would be the point of using Java to interface between C/C++/Objective-C apps? None.
This article is just plain wrong. True, a few years ago, France was one of the few country in the world where encryption was illegal, along with Iran, Irak and North Corea. I think that even today you're legally limited to 128-bit encryption, but nobody gives a shit. I think that most legislators never heard about such a thing as encryption, let alone key escrow. Basically no legislator gives a shit about computer security because there are other more important problems, like getting reelected through FUD. France's policy on computer security is simply one long string of oddities, mainly composed of long forgotten fags nobody cares about anymore. It's quite nice actually! No DMCA, multizones DVD players everywhere...
Actually, the real question is: why do you have to pay when someone calls you? The answer is simple: the phone system is broken. Fix it, and solve all the problems at once without any kind of bill or lawsuit. Easier said than done, but Europe, Asia, Africa and South America managed it (not sure about Australia). Granted, they leapfrogged the US by going to GSM directly. That's not a reason to stay behind.
Reading books is better

General IT Books?

Having a nice library is good, but reading books is better. Do you know how long it takes to fully assimilate one of these books? At least weeks for some of them. So you don't really have time to understand them (unless you're 1) employed, 2) rich).
My point is: pick something and get good at it. As you move to more complex projects, everything will come together and you will avoid the "why in hell did I learned that" feeling. Heck , my last project uses J2EE, PostgreSQL, a geographical information system, a graphic toolkit, some shells scripts and some C programs, plus the obvious OO design.
You have a large piece of code written in a proprietary language that probably noone will know about in 10 years and you want to convert it to Java. I don't know why but I bet that the word "web" is in it. The reality is that you have a WORKING and DEBUGGUED large piece of code. Why don't you just reuse it? Why don't you just bolt an adaptor on top on your project? Corba is especially good at it, it has mapping for most languages and integrates seamlessly with J2EE. Sure it won't look as good as a pure J2EE project, but it will be a lot cheaper, and will probably work a lot better too.
It seems to me that UnitedLinux will look a lot like SuSE 8.0 ( very fine distribution): Kernel 2.4.18 or higher glibc 2.2.5 gcc 3.1 XFree86 4.2 KDE 3.0 Acrobat Reader
I'm happy to see some companies actually promoting standards and interoperability. I think that this is very very good for the future of Linux.
I heard about that on national TV. It's just lame.
HackerZvoice is just a crappy "magazine", 20 pages long. It contains usefull tips like "How to bypass the Windows 98 password in 30 seconds" or "How to mount an publicly shared NFS drive remotely and feel 3l33t".
It makes me ashamed to live in France. Hopefully we don't have the DMCA over here...
What is important to realize is that in order to use these boxes as a cluster, you will have to wrote you own custom software. Yep, it means C and C++, and hours of hacking.
But as mentioned in a previous post, Mosix can do that for you, if and only if your program can use several instances at the same time. Compressing MP3s is a good example.
The problem with the TelMex card is that they are even dumber. They aren't made with flash mem (expensive). They are made of fuses. 1 unit == 1 fuse. The phone blow a fuse each time a unit is consumed. If you are really into that, you could put an EEPROM on your card, and simulate the behavior...

Well, this article is just empty. It just says "There is a Code Red III" and that's it...
The problem is that these protocols are expensive in CPU time. Sure sometimes the Not-Invented-Here syndrom bites them hard, but usually the problem is that theses protocols aren't fast enough. 2 seconds to encrypt an email is ok, but you need to encrypt 5Mb/s here, with just some little chips on your card.
Ever heard of mod_gzip? It compress anything that goes trough your Apache webserver and it is supported by most browsers. With everything running over http theses days, this is the way to go...
Writing virus is as simple as opening Word! (Yes I know Code Red is a bit more complicated, it's written in Delphi)
Come on, this is completly predictable. What really amuse me is the fact that we haven't seen a really dangerous bug yet: something along the lines of Code Red, mixed with CIH (destroy motherboards), that format each hard-drive it encounter. Are virus's writers responsible or what? This would make the Internet a lot more secure, one way or another. And yes, this is a Microsoft worm for God sake's !
I used to be one of theses. I used to think that I new all I needed about Unix. Then I stepped out of my bedroom and discovered the real world. Where things are not so simple. Where downloading a little something from whatever warez site when I needed it is not an option. Where going root to fix something is usually not the good way to do it. In a word, real-world enterprise-style computing.
And this my friend, isn't something a 15-year old can grok (usually there is exceptions I guess, but I'm still looking for one. I just remembered theses two "sysadmins" college kids that didn't knew what colocation was.)

Explain too me: with SSH, passwords and logins are encrypted when sent. You can't just snif them. They never travel over the medium.
