People seem to forget the true way for Linux to compete... instead of maybe spending so much time on WINE, prehaps a better investment is to work on fast Java Virtual Machines..
They are getting faster, in fact Sun plans to release JDK1.4 soon, and it is MUCH faster than JDK1.3.
Now, once Java is comparable fast to native applications, (which in some situations it already is), developers can start writing applications in Java commercially.
Once this happens, any OS that supports Java can run those applications. Example:
Lets say some day down the line, 20% of the programs you can purchase in the store is written in Java.. well, that means ANY operating system can run those programs if they elect to run the OPEN java specs.
So in summary, the true way to open up the opearting system market is to get developers to use Java.
If you wanna be technical, wider is not really better. All it does is make your car a more pain in the ass to park. I'd rather have a smaller car.
As far as stability, better cornering, and safety goes.... get a firmer spring rate in your suspension and you will achive the same thing without being a road hog.
The playstation 2 has perfect motion blur. It is automatic also. What is really cool is that bright objects on the playstation 2 blur faster than dark ones..
Like if a bright light is traveling in a circular motion it will streak to form a circle. Which allows it to look like the FPS is insane.
A game which uses this well is Devil May Cry, there is another game which I saw that way OVERUSED it called the Bouncer.
This guy had bright red lit eyes, and if you smashed him across the screen there would be a nice red streak.
Techncially you are correct, but in practice you are not. The human eye is limited to how many unique frames per second it can tell the difference between.
There are 2 reasons FPS matter.
1) Put 2 games of quake3 next to each other, one with 30fps and another with over 100fps. The extreamly high fps will sometimes "blur" things past you, its amazing and hard to explain with words.
2) In high action sequnces your FPS slows down. If you are getting 30fps sitting still in quake3, when 2 rockets blow up next to you and 6 guys are on the screen you are probably getting 15fps or less.
Programs like this exist in the wild, spyware programs included with CuteFTP and the like do that very thing. I first found it odd they were making outbound connections, but the only trusted application I had was Internet Explorer.
This was... 2 years ago, so i'm sure its common today. The only safe thing to do anymore is to have a windows box, JUST for the purpose of web browsing and keep it behind a proxy at that.
Its a pretty simple concept, we have a program that allows us to edit all.html/.php/.jsp/etc files on any of our web servers with a web based interface.
If one of these "stastical" programs captured my entire POST when I updated lets say... a PHP or JSP page, they would have source code to one of my other web based porgrams.
And furthermore, there are servers that access files on my web server that are DEFIENTLY not linked from ANYWHERE on the WWW or my index.html.
Curiously, I found a few spyware programs on my computer that I got from using Gamespy (ironic huh?). Lavasoft is cool, and helped me get rid of all those programs.
Fortuantly, that has a password on it, and it won't even let you in unless you access via HTTPS. BUT, what if I was using security through obscurity?
What if one of these spyware programs searches for username/password combinations and sends them encrypted with what "looks" to be statistical data?
The fact of the matter is, this is crap, and no one should try to even defend these people.
I don't see the difference, anytime a program subvertly installs itself to my computer without me asking, and THEN violates my privacy pisses me off. If someone wrote a virus that did this, they would be in jail, but since as I said.. Corporations wrote this, we can't do shit about it.
There are many things printf can't do for you. It can't check your stack. Sometimes, your code crashes when its executes a RETURN statement. The reason is that the stack is corrupted, and it has no idea exactly where to return to.
You also don't have to single step through code.:P You can jump through code with breakpoints just as fast with printf, with the advantage you can stop and take a look around if you notice something funny.
IDEA cut our development time in half, no lie. Its only $400.. and umm, you need at LEAST 128 megs of RAM to run it. Stupid memory hungry swing apps.. but check it out, defiently.
As of just a few months ago, we had to download the sdk from sun. Than apply a series of patches, than do a hopeless compile that never worked due to some reason or another. It usually failed due to some X library or another, which sucked because all we wanted to run was Orion.
The ports entry for it is rather recent, and I am happy that you pointed it out to me. Just goes to prove how FreeBSD is always improving and evolving over a matter of months instead of years.
Another question is this, why is sun such a nazi about its jdk? It would be incredibly nice to be able to "fetch" the jdk instead of creating an account on sun just to download it.
We run on alot of small systems, we are talking 8-16 megs of ram here and pentium 75ish processors. We tried to use linux once, but when linux runs out of memory with the old VM, it sucked HARD. I mean, I had processes being swaped out of memory compleatly that were ACTIVE!
Why do we use such small systems? Because we want them to perform under extream load when placed on larger systems. Its smart really, its easy to benchmark a few functions on a pentium 75, than a 2 ghz pentium. If your application doesn't run peppy with one usuer on a pentirum 75, it sure as hell won't support 1000 users on 2 ghz pentium.
Thats why we have used FreeBSD for all this time, in FreeBSD the VM manager is perfect, and isnt' even slated for upgrade in the near future due to the fact it works like it should. If you are using telnet on a FreeBSD machine, and _one_ applications uses a ton of resources, that one application will run slow. But your telnet will continue on fine. Try putting 12 megs of RAM in your machine, than compiling PostgreSQL while using a telnet session. You won't even notice the compile on FreeBSD, but you will with Linux.
Funny enough, this also ties into the article earlier regarding why Linux isn't used for alot of large scale databases. Databases consume HUGE amounts of RAM and the OS under it has to be peppy about it. Linux in the past has been tuned for desktop/single user performance and not what those databases need. They need TONS of resources, and quick _CONSISTANT_ access to it.
That said, I am very happy to see them getting a better VM. Because my biggest problem with FreeBSD is its crappy java support, the most recent stable JDK it supports is 1.2.2. And thats in Linux emulation mode!
So if things work out, and Linux supports java well, and doesn' crap out when it runs out of resources. We will defiently switch to Linux, and life will be good!
What, so we should write BIND in java? Fuck that, you seem to forget that languages that provide bounds checking, are WRITTEN IN C. Its just as likely java itself has a buffer overflow in it, as the bind program. It makes no difference. The only difference is, in C, you have controll. You decide if your program is a POS with holes, of if its solid.
And second of all, I don't care if someone hacks BIND on my system, its called jail(), BSD has it, do you? I'll make sure and put some porn with my zone files, so the l33t hacker who hacks my l33t bind install gets free pron for his effort.
CGI means.. Common Gateway INTERFACE. To many dumbasses out there think CGI is a C program or a perl script or whatnot.. It isn't a program, its an INTERFACE. All web languages use CGI, java, mod_perl, mod_python, everything. When you put text in a textbox, and hit submit, thats normally CGI. (unless the form uses mail, or whatnot).
Now personally, is this Mozilla idea a good one? Probably not, only a serious developer would need this, and a serious developer already has a webserver on their LAN. And if you are worried about being on the road, make the web server accessible via SSL and some type of login method. If you don't wanna do that, put apache on your web server. On my pentium 75 laptop, with 16 megs of ram, it only takes.021 seconds for php to server a page that says, "Hello World".:)
Ohh wait, are you complaining that a web server is too hard to setup with ssl?
Something is considered a troll because it is a truth? My research on the site showed it had plenty of available bandwidth, objects were loading fine from the webserver, unless it included java code.
Even if it was crappy hardware, who cares? I have pentium-75 machines with 32 megs of ram that can saturate a T-1 with dynamic php/perl content, yet that same machine could barely handle one user when displaying "hello world" in a java servlet.
Programmers should focus their development on low-end hardware. Simply because if it runs fast on crappy hardware... it will run awesome on your client's machine.

This article failed to state why this "new" technology is better than existing technologies that work incredible well. It seems this fabric would lose its properties over time (or if put up to a cigarette lighter for long). Not to mention water can pass through the material if "forced" (as the article stated).
Gore-tex clothing has been around for quite awhile, its also water-proof. If you are wet underneath the Gore-tex layer, your body heat will evaporate your prespiration, turn it into water vapor, which is a small enough particle to pass through the Gore-tex layer and escape. I'm extreamly happy with my camping bag, pants, windbreaker, "gators", etc made of the stuff.
The T1 is apparantly not the problem. Try to view any of the graphics directly off the server, and they load fine. The main page just takes awhile to process your request, once it does it downloads lightning fast. I would'v suggested using a faster php/perl based approach than... java... for such a cpu intensive site.
The OS discussion is no different than the game console discussions. It boils down to the software. What "Linux"(Why does everyone here say Linux? My business sells BSD systems *shrug*) is alot of good applications that can be used in business. My company has a few projects, but no investment capital so these are going slow... 1) Bootable CD, it starts off bsd, locates drive, formats, runs BSD off the CD, and data on the drive. It will come with Apache/PHP/PostgreSQL installed. Now on some CDs we will put different versions of our software. Our main one being Glimpse, which is a business management/POS software can be included in the PHP scripts. So you pop the CD in a computer, boot it up, type in its IP address. And bam! Software installed, go around to all the clients web servers, make the home page be the IP of the server we just installed, and they run all the software from there. There is a profitable world out there, but Linux hits a big hurdle in its license. FreeBSD uses the BSD license, which is a usefull one. Thats why apple is using it in MAC OS. Linux is free to use, but making money off it? I dunno, thats why we use BSD and PostgreSQL, less licensing issues.
Sorry if I offended anyone, but "Linux" as it stands sucks, and everything with it. Everyone is so busy doing nothing, or coding useless features, its disgusting. You have to make devices work, not by recompiling a kernel, but autodetected, and installed on the spot. You have to make standard documentation, (check out the manual on www.freebsd.org as a start, but even that is too technicall at points), you have to make it so the server can be set up without ever seeing a command prompt, steps being explained logically, and lastly developmental tools. Last I checked, I was the only one who even submitted a php editor to www.zend.com, (someone coincidently downloaded that and make a GREAT version of it, when I finish moving and get all my computers out of boxes, I'll post the link to it). PHP could propell the "Linux" world if developers could pop a CD in a machine, grab another computer on the network, open the web browser to the server, and start working immediatly.

The scary trend to me, is that innocent people are busted all the time for crimes they didn't commit. But how many people here are sysadms who have tracked down hackers, presented the FBI with all the evidence they need. (Logs, ethernet captures, the crook's physical address, etc) and nothing happen?
A few years back I received a 16 point distributed DOS attack, (before most people knew what it was), i verified with each sysadm(mostly colleges and small business), their machines were verified being broken into. The worst hit site was lsu.edu, I spoke with their admins, and they checked their boxes and founds thousands of dollars of damage.
To this very day, a guy lives in new mexico, never got busted for the attack. (He was threatning from irc from his dialup account as he was attacking me). Why did he attack me? I was using "his" nickname. Turns out I went on vacation for 6 months from the net, came back, used my old nick, and some "hacker" decided it was his, and would flood me off the net to take it back. *rolls eyes*
I use PostgreSQL myself, and I never have to lock rows, its done automaticly for me by transactions. Mysql team has stated many times adding things like this requires almost a complete re-write of the database to make it work. It works well in PostgreSQL because rows are never deleted. They are appended when updated, and the old rows are still available. When no clients are connected that are using the old rows in a current transaction, it deletes the old rows the next time it finds it. Pretty simple, and it works fast. I am not another lamer saying, hay use PostgreSQL its cool. I am saying, it works. Derk
