You don't seem to get it. Small closed computers like this one aren't very much to produce at all, especially if you're ordering them inquantities of hundreds of thousands. PCs have low margins because of all the components on separate PCBs. If everything fits onto a single PCB and you put as many logic units onto the same die as you can fit, you've got a really inexpensive system to build. Radio electronics are inexpensive as well which means setting up a radio packet network in rural areas isn't really THAT difficult. A bunch of ham operators could build a nice little network pretty efficiently.
Mac OS X is going to be primarily run by a bunch of consumers, of course it will be a major crack target as popularity of it increases. Alot of people are going to end up calling tech support wondering why their passwords don't work or why their personal files have been wiped out when they left their computer connected to their broadband connection for a little while. Or they're going to wonder why they are suddenly sending out massive amounts of net traffic concurrently with major websites being DDoSed. For most of the people here this is almost a non-issue, slashdot users are at least aware that their security is insufficient. OSX users here may or may not know about osxsecurity.com or osxtalk.com both of which provide slash-ish forums pertaining to OSX. Consumers for the most part are in the dark, SYMANTEC. They'll pop out an OSX version of their internet security suite which will basically be some scripts to edit hosts.deny and/or provide a front-end to ipfw. Lots of consumers will pick this software up over the next couple months, ESPECIALLY if OSX specific cracks start happening en masse. I'm sort of hoping Apple decides network secuity is a valid reason to spend some dough and works at getting their OS up to snuff with Unicies better configured out of the box for security.
Modern computing concepts == bad. Look at your Linux "boxen" humming away under your desk. You're running a personal computer with a mainframe system. Even our concept of servers is pretty stupid. You have this server that is meant to hum away while its kernel supports multiple users to log into it for time sharing. Lets move away from mainframes since we are now officially in the 3rd millennium. Web servers ought to be little more than network appliances that you can tell "serve these pages and these scripts and apps to these connections and link up with these nodes to form a cluster" or some such and they will happily chug away at it. IBM's concept is what ought to be happening now and not in response to a diminished supply of skilled labour.
Yeah all that technology works fine until someone drops EMP bombs over the battlefield or arms mobile anti-personelle units with masers to zap the fuck out of your electronics. Half of this technology is useless against a high tech opponent anyways. Electronics are very susceptible to fucking up and being fucked with and an old axiom with anything is more complexity leads to a higher potential of failure. Adding a bunch of electronic toys to a soldier doesn't make him a better soldier. As proved so many times, technology is not a military cure-all. If you invade me with a bunch of electronic soldiers I'll EMP bomb your ass and fill the air with radioactive chaff; once your units are cut off I'll use plain old napalm to wipe them up.
I'm not being zealous for any particular chipset or processor. Trying to attack my argument on grounds of being "typical and transparent" is ludicrous. How about some factual basis why my argument isn't sound. You'd be hard pressed to come up with a decent argument due to your apparently infantile reasoning ability. The K6-3 was a major blunder for AMD because they lost money on its production. They had a low production volume and the on die L2 cache only added to the cost in silicon. Three cache layers the fastest of which runs at the speed of the memory clock? Thats not what I call a great idea. The K6-3's performance was NOT on par with that of a P3 in any sort of test you could run. They also timed the release of the K6-3 badly compared to the release of the Athlon. The K6-3 was a competitor for the P2 and a poor one at that which was too little too late. The Athlon however was released concurrently with the P3 to act as a direct competitor for it. My friend's Athlon 500 tops my P3 500 (Katmai) in 3DMark by a couple points with really similar hardware which made the Athlon a nice choice for people interested in the most bang for their buck. I think the P4 is almost as much of a mistake as the K6-3 was, it costs alot and performance per clock isnt on par with competing chips. Your comment is all I expect anymore from the ten year olds frequenting slashdot nowadays.
Wow the great wall is in China? I'm absolutely amazed at your mental accuity. There is alot of controversy over the dam, it is going to be supplying central China with lots of power but is also costing the state the equivilent of 10 billion dollars. Not only the immense cost of the dam but the fact the relocation and the quelling of labor strikes has been dealt with in a particulaly nasty fashion. A million or so people are going to have to be relocated, most of these people are farmers who get to go from well irrigated arable farmland to much less desireable land elsewhere. The Shanghai tower project is more of a pissing contest than the Three Gorges dam though. The TGD at least provides some way to make up for the 10 billion being poured into it. A 3.7km vertical city in Shanghai is more of a publicity stunt with little resell value. How do you justify spending uber billions on a 300 story tower skyscraper whose functions could be more easily sussumed by cheaper and more easily built structures.
Why are there so many AMD zealots around? What they fuck do you think you're supporting? The goodness of mankind because Intel is somehow evil? AMD is a publicly held corporation just like Intel and they've made as many hardware mistakes as Intel has in the past (the K6-3 for example). "I switched to AMD because of the FP-DIV erro" or some stupid bullshit just goes to show how easily led you are. If you're going to choose a chipset choose it because you're really getting the most for your dollar. Right now AMD gives you the most for your dollar. So pick it because of that not because of a floating point bug only 1 in a thousand people ever ran into.
Technically the P4 is a pretty good design for a processor and would in actuality be a really good processor if Intel had done some pre-release planning. Before the launch of the P4 developers should have been offered P4 reference boxes and a completed 5.0 version of their compiler at very reasonable (VERY LOW) prices. This would have given them lots of time to recompile and optimize their binaries so when the P4 came out they could offer a P4 upgrade of their applications. This would have provided a better market for the P4 when it was launched. If I'm Joe GraphicsDude working on my aging P2 450 system and Adobe sends out an email saying I can get a P4 optimized set of their graphic design apps for a low low upgrade price, I can take that to Joe PriceWaryEmployer and ask for a small investment to get me more performance and thus more output. The Intel engineers had to stick a simpler FPU on the P4 due to remain within their transistor budget so the FPU performance of the P4 is lower than that of the Athlon. However if some operations were redone to use SIMD instructions as opposed to FP instructions they could bypass the crappiness of the FPU and get similar if not better FPU performance out of the P4.
As explaied so many times to so many stupid people clock speed != performance. The fact a 1.7 GHz P4 competes with a 1.2GHz Athlong Tbird shouldn't really be a point of contention. The 2GHz P4 ought to easily best a 1.33GHz Tbird (assuming the gigaheartz to gigahertz performance ratio is kept) and the P4 can easily be clocked up to 3Ghz while the Athlon line will top out around 1.5GHz. I think the hardcore performance coming out of the P4 core won't be seen until Foster (Xeon) is released at the end of the quarter. The bigger cache with its ultra high bandwidth data channel to the processor will make it a powerhouse performing lots of the same instructions (ray tracing for example). The DP and MP versions of Foster will probably make it a killer in the graphic workstation market. One note to developers, do a better fucking job of threading your apps. The Xeon is going to have hardware support for SMT and deep pipeline of the P4 makes multiple threads work good so write your apps to make better use of threading. I know some things are really hard to thread because you can only do perform some functions once other functions have completed by please try! Anyone with more than one processor in their system can attest to how rarely a program is effectively using both processors. The new Xeons will have lots of bandwidth and a deep pipeline use it!
Okay I just hope this thing gets built with a little better quality controls than Shanhai normally uses for public structures. I've seen pictures brought back of lopsided buildings and power lines run over trees rather than power poles. China is going to desparate measures to get their name of the list of countries with World Wonders while throwing caution to the wind. The three gorges dam is a good example of this. THey are destroying archeological sites as well as displacing thousands of people in order to make a resivoir of questionable use to the public.
Actually there is a good reason to write servlets. Not everything requested of your webserver is going to be HTML. In the case of a client making a GET request to the server for some XML file or database object you would much rather have a servlet processing the request than a JSP page. You could use the same beans with the servlet as you used for the JSP if you wanted. Servlets are also good when you need to take data from somewhere like a database and turn it into some other form of data like a graph. Using a JSP page would make the HTTP transaction far too long and your connection will probably time out. Using a servlet to do the hard work and then send it to the client over a separate connection is more friendly for the client who'd like to see at least SOMETHING load onto the page.
Your example is alright but you're ignoring the fact that to the machine Java is handling a string almost exactly the same way PHP is. The main difference is to the programmer. Simple percentages aren't really an indicator of language performance. Also JSP != servlet. A servlet is a fully compiled program you run with CGI where JSP is an HTML document containing java code that is executed when the page is loaded. JSP should be compared against ASP languages rather than Perl and PHP.
It makes me feel old to think that I've been doing the whole MP3 thing for several years now, back before the Linux kernel had hit 2.0 and the NASDAQ was healthy when it was below 2000. The rather recent popularity of MP3 trading, facilitated by faster internet connections and programs like Napster, is just amusing to me because I remember getting shit off newsgroups or maybe a handful of IRC chanels that even had a conception that you could compress music to a transferable size. Did anyone here use Oth.net? Ahhh, anonymous FTPs for file trading. WarFTP and Serv-U never had it so good. Anyways the point of this rambling is to remember that Napster only facilitated MP3 trading's popularity, they didn't really come up with anything profound. Until the RIAA makes it so you can only listen to music through a microtranceiver in your molars people are going to copy and compress music and look for music they don't have on CDs.
Stop whining about the RIAA anyways, they will never "get it" because they are business men. See they work with late nineteenth century industrial ideas in their heads because thats what they learned in business school and it is how mass manufacturing works. The RIAA will vehemently claim they are losing money due to MP3 trading because they have a monopoly on music distribution, therefore if you're listening to music they didn't sell you they have lost money (technically). It's a nice scheme they have worked out. You sign your work over to them and they are contracted to you to provide such and such services for you. That is why people want fucking record contracts. How come you can't just go solo? THE ENTIRE BROADCASTING INDUSTRY IS BUILT AROUND THE WAY THE RIAA DOES BUSINESS. The FCC makes it difficult for someone to get any FM bandwidth in a given area, you need serious funds to get into the business. This is where ABC, NBC, and CBS come into the picture. They make cash off the advertising their little darlings run inbetween the hit songs all the kids tune in to hear. Ever wonder why there aren't more free form radio stations? They have to play what advertisers will pay to have their commercials run with. It's the same reasons radio stations can offer you a thousand dollars for listening at a certain time. Advertising is sold at a prime rate and a thousand dollars is a small portion of that.
Napster bowing down to the RIAA isn't so much bowing down as it is to losing the ability to fight. They can only afford legal services for so long before they are run into the ground. The RIAA lawsuit knows this and thats why they went to court with such blatantly retarded premises. Their goal was to take Napster down before its shell had hardened. I doubt they expected them to put up so much of a fight. It doesn't really matter to them though. A sullied reputation doesn't amount to much when you own 90% of all recorded music. Acoustic fingerprints of songs will probably start to keep alot of people from trading more popular stuff. Thats life, tough. Find a different way to trade your copyright infringed material. Yeah it is less than legal. Putting music up for trade seriously skirts the bounds of the home recording act as you're giving it away for no monetary compensation. Napster is getting into trouble because they have made money facilitating the trade of material with questionable legality. Do I care if Napster doesn't let me trade a fingerprinted song? Not really. I'll go back to getting songs by old fashioned methods. Or I'll go down to a library and rip their public access CD collection. I don't give a fuck about anything except having alot of music that I like readily available to me.
The problem with transmitting yourself one atom at a time lies with having to destroy yourself and thus all the molecules in your body in order to transmit yourself. They are sending individual atoms that have little better to do than be the subject of experiments. The atoms in my body and yours are much too busy right now to bother with being guided through anywhere.
Stop whining about ISPs axing accounts of people downloading files of questionable legality. It is a VERY simple calculus for the ISP. You pay them x numbers of dollars per month which over the course of a quarter amounts to so much revenue (4x). Then say the MPAA comes along and says "Cut of Joe GnutellaUser's broadband account or we'll see you in court for aiding his downloading of illegally copies movies!". The ISP quickly calculates the revenue you add for a quarter and compares it against the cost of an attourney showing up in court. If what you add to the company's revenue is less than what stand to cost them, they cut off your account.
It can be argued that you can rip CDs to MP3 and share them over services like Gnutella and Napster as you're not making money or anything and there are no glaring warnings against said practices on the CDs. However, if you watch one of your downloaded movies and see the FBI warning about copying and redistributing the movie you're about to watch the thought should occur to you that you're not quite operating within the bounds of the law. Whether thats right or wrong doesn't matter. What does matter is that warning as well as explicit copyright prevention measures gives the MPAA plenty of legal backing to persue people making copies of and trading their movies via the internet. They aren't taking away any of your fucking civil rights. They are upholding their fucking copyright like the copyright laws REQUIRE THEM TO. Yes the sales scheme and market control the MPAA uses is fucked up. I think Joe Valenti is a dipshit both personally and professionally and the MPAA is a crock of shit. This still doesn't give people reason to whine after getting caught trading legally questionable material on peer to peer sharing services.
Internet access is not a civil fucking right. Besides which you are paying for a service from a corporation. If they are threatened with a lawsuit if they don't axe your account they're going to drop your account faster than you can say "Wait that's unfair". Internet access is not fucking essential either. If it was so fucking essential you wouldn't be downloading movies under questionable legal premises would you? As for the ISPs think of it this way, they're making a scant revenue (40 or so dollars a month, a decent portion of which is not profit) from your personal account. If the MPAA sues them the legal bills merely for serving a court summons will cost more than you pay in a year.
Electrical wiring alternates at 60 Hz in the US. Wires running parallel to it will means you're putting them inside the wires' magnetic field. This causes induction in your audio/video/network cabling and thus static and in the case of audio wiring a 60Hz hum. This happens even with well shielded wiring so always run cabling perpendicular to electrical wiring. You can easily LAN party with a single RJ-45 jack by wiring the jack to cross over and plug a cable into the jack and the uplink port of a hub or switch. This will connect the hub to the rest of your network and you'll be rocking and rolling. Even better set up a LAN party room with a hub and plenty of power jacks in it. Maybe wire your garage to be your LAN party room. Instead of a 24 port hub get an 8 port switch and assign each port to a wired room of the house. You can plug hubs into your switch if you want multiple comps in the same room connected to the rest of your network. The good thing about a central switch with hubs on star branches is if your nodes are only talking locally (in the same room) the rest of the house won't have its bandwidth filled up by their chatter.
What in the holiest of holy fucks are you talking about? Did I not say Jabber is an XMl router? There are plenty of limits with what you can do with it, the fact that it's XML makes little difference. I could do everything Jabber does with a simple IRC server. Like I fucking said, Jabber is a framework someone can easily put to their own use, the key to its success will be someone putting it to a very popular and profitable use. All you've done is name a few of the things you can do with an XML router. Congratulations jackass.
You can run a network service on any port of your choosing but if my client isn't trying to access your server on the right port I CAN'T CONNECT TO YOU.
You can get them from just about anywhere first off (start at Radio Shack) and secondly don't be a retard about cabling. Run signal cabling away from electrical wiring and if you have to run it by make sure it crosses the electrical wiring at a 90 degree angle (perpendicular to the run of the electrical wiring) or else you'll have lots of signal problems. Do you NEED RJ-45 jacks every ten feet? THink about that before you install them. Think along the lines of a wall mount with two or four jacks in it rather than a mount with a single jack.
The Jabber protocol is cool not because of interoperability but because they've whipped out a pretty fast XML router. Jabber is as complex (actually less so) then Gnutella and look at how popular Gnutella is getting with the mom and pop crowd. The protocol is fairly basic and easy to work with and allows you to add features onto it later. Jabber is a good framework to build on rather than a release product like AIM. Jabber will make a big splash as soon as someone puts all the good ideas into one easy to use package.
What the fuck? Port assignments are an RFC stanrd (I don't remember exactly which one) they aren't just random assignments people decided looked pretty. Theres 65000 or so ports because the designers of TCP weren't exactly sure how they were going to be assigned. You can't just open up 65,000 or so ports to the outside world. Thats how people easily DoS your network.
Unfortunately only HTTP 1.1 supports a hostname in the packet header. Most web hosts use virtual hosts in order to stick a shitload of domains on a single server (and thus IP) and charge you a bit of mula for it.
You've got to be joking? Java and/or Objective C is going to run slower in the long run than the equivilent C++ program (don't say C/C++ when comparing it to an OO language like Java, its bad semantics). The language running inside the VM has more overhead for external operations. Ever use emacs? FUCKING SLUG! Its written in Lisp oddly enough. What exactly does Java do that you aren't going to be able to do in C++? Don't blame C++ for the memory footprint of Konqueror and KDE.
What the fuck are you talking about? Memory has little to do with the integer or floating point performance of a fucking processor. Apple already has a bit of alliance with IBM as partners in development of the POWER series processors. Your god box sounds like a sad joke. Dual CPUs adds more pressure on your memory bus as it now needs to feed two processors instead of just one. Besides that alot of programs (especially windows ones but a large percentage of GNU apps) aren't really designed to take advantage of multiple processors. Instead of trying to jam two processors in pick something that you're going to get the most operations per second with good memory bandwidth. Along with bandwidth you need macho amounts of RAM.
What the fuck are you suggesting? Why would I want to write toolkit code (GTK, Qt, ect) in a language that has to be run in a virtual machine? The point of writing shit small and fast is so they don't overuse your system resources. Why should something relatively simple like animating a widget interaction take 80% of your processing power? I can't believe someone marked this drivel up to 3 as interesting.

Advertising is sold at a prime rate and a thousand dollars is a small portion of that.
Napster bowing down to the RIAA isn't so much bowing down as it is to losing the ability to fight. They can only afford legal services for so long before they are run into the ground. The RIAA lawsuit knows this and thats why they went to court with such blatantly retarded premises. Their goal was to take Napster down before its shell had hardened. I doubt they expected them to put up so much of a fight. It doesn't really matter to them though. A sullied reputation doesn't amount to much when you own 90% of all recorded music. Acoustic fingerprints of songs will probably start to keep alot of people from trading more popular stuff. Thats life, tough. Find a different way to trade your copyright infringed material. Yeah it is less than legal. Putting music up for trade seriously skirts the bounds of the home recording act as you're giving it away for no monetary compensation. Napster is getting into trouble because they have made money facilitating the trade of material with questionable legality. Do I care if Napster doesn't let me trade a fingerprinted song? Not really. I'll go back to getting songs by old fashioned methods. Or I'll go down to a library and rip their public access CD collection. I don't give a fuck about anything except having alot of music that I like readily available to me.
A Beowulf cluster of Beowulf clusters of course.
The problem with transmitting yourself one atom at a time lies with having to destroy yourself and thus all the molecules in your body in order to transmit yourself. They are sending individual atoms that have little better to do than be the subject of experiments. The atoms in my body and yours are much too busy right now to bother with being guided through anywhere.
Stop whining about ISPs axing accounts of people downloading files of questionable legality. It is a VERY simple calculus for the ISP. You pay them x numbers of dollars per month which over the course of a quarter amounts to so much revenue (4x). Then say the MPAA comes along and says "Cut of Joe GnutellaUser's broadband account or we'll see you in court for aiding his downloading of illegally copies movies!". The ISP quickly calculates the revenue you add for a quarter and compares it against the cost of an attourney showing up in court. If what you add to the company's revenue is less than what stand to cost them, they cut off your account.
It can be argued that you can rip CDs to MP3 and share them over services like Gnutella and Napster as you're not making money or anything and there are no glaring warnings against said practices on the CDs. However, if you watch one of your downloaded movies and see the FBI warning about copying and redistributing the movie you're about to watch the thought should occur to you that you're not quite operating within the bounds of the law. Whether thats right or wrong doesn't matter. What does matter is that warning as well as explicit copyright prevention measures gives the MPAA plenty of legal backing to persue people making copies of and trading their movies via the internet. They aren't taking away any of your fucking civil rights. They are upholding their fucking copyright like the copyright laws REQUIRE THEM TO. Yes the sales scheme and market control the MPAA uses is fucked up. I think Joe Valenti is a dipshit both personally and professionally and the MPAA is a crock of shit. This still doesn't give people reason to whine after getting caught trading legally questionable material on peer to peer sharing services.
Internet access is not a civil fucking right. Besides which you are paying for a service from a corporation. If they are threatened with a lawsuit if they don't axe your account they're going to drop your account faster than you can say "Wait that's unfair". Internet access is not fucking essential either. If it was so fucking essential you wouldn't be downloading movies under questionable legal premises would you? As for the ISPs think of it this way, they're making a scant revenue (40 or so dollars a month, a decent portion of which is not profit) from your personal account. If the MPAA sues them the legal bills merely for serving a court summons will cost more than you pay in a year.
Electrical wiring alternates at 60 Hz in the US. Wires running parallel to it will means you're putting them inside the wires' magnetic field. This causes induction in your audio/video/network cabling and thus static and in the case of audio wiring a 60Hz hum. This happens even with well shielded wiring so always run cabling perpendicular to electrical wiring. You can easily LAN party with a single RJ-45 jack by wiring the jack to cross over and plug a cable into the jack and the uplink port of a hub or switch. This will connect the hub to the rest of your network and you'll be rocking and rolling. Even better set up a LAN party room with a hub and plenty of power jacks in it. Maybe wire your garage to be your LAN party room. Instead of a 24 port hub get an 8 port switch and assign each port to a wired room of the house. You can plug hubs into your switch if you want multiple comps in the same room connected to the rest of your network. The good thing about a central switch with hubs on star branches is if your nodes are only talking locally (in the same room) the rest of the house won't have its bandwidth filled up by their chatter.
What in the holiest of holy fucks are you talking about? Did I not say Jabber is an XMl router? There are plenty of limits with what you can do with it, the fact that it's XML makes little difference. I could do everything Jabber does with a simple IRC server. Like I fucking said, Jabber is a framework someone can easily put to their own use, the key to its success will be someone putting it to a very popular and profitable use. All you've done is name a few of the things you can do with an XML router. Congratulations jackass.
You can run a network service on any port of your choosing but if my client isn't trying to access your server on the right port I CAN'T CONNECT TO YOU.
You can get them from just about anywhere first off (start at Radio Shack) and secondly don't be a retard about cabling. Run signal cabling away from electrical wiring and if you have to run it by make sure it crosses the electrical wiring at a 90 degree angle (perpendicular to the run of the electrical wiring) or else you'll have lots of signal problems. Do you NEED RJ-45 jacks every ten feet? THink about that before you install them. Think along the lines of a wall mount with two or four jacks in it rather than a mount with a single jack.
The Jabber protocol is cool not because of interoperability but because they've whipped out a pretty fast XML router. Jabber is as complex (actually less so) then Gnutella and look at how popular Gnutella is getting with the mom and pop crowd. The protocol is fairly basic and easy to work with and allows you to add features onto it later. Jabber is a good framework to build on rather than a release product like AIM. Jabber will make a big splash as soon as someone puts all the good ideas into one easy to use package.
What the fuck? Port assignments are an RFC stanrd (I don't remember exactly which one) they aren't just random assignments people decided looked pretty. Theres 65000 or so ports because the designers of TCP weren't exactly sure how they were going to be assigned. You can't just open up 65,000 or so ports to the outside world. Thats how people easily DoS your network.
Unfortunately only HTTP 1.1 supports a hostname in the packet header. Most web hosts use virtual hosts in order to stick a shitload of domains on a single server (and thus IP) and charge you a bit of mula for it.
You've got to be joking? Java and/or Objective C is going to run slower in the long run than the equivilent C++ program (don't say C/C++ when comparing it to an OO language like Java, its bad semantics). The language running inside the VM has more overhead for external operations. Ever use emacs? FUCKING SLUG! Its written in Lisp oddly enough. What exactly does Java do that you aren't going to be able to do in C++? Don't blame C++ for the memory footprint of Konqueror and KDE.
What the fuck are you talking about? Memory has little to do with the integer or floating point performance of a fucking processor. Apple already has a bit of alliance with IBM as partners in development of the POWER series processors. Your god box sounds like a sad joke. Dual CPUs adds more pressure on your memory bus as it now needs to feed two processors instead of just one. Besides that alot of programs (especially windows ones but a large percentage of GNU apps) aren't really designed to take advantage of multiple processors. Instead of trying to jam two processors in pick something that you're going to get the most operations per second with good memory bandwidth. Along with bandwidth you need macho amounts of RAM.
What the fuck are you suggesting? Why would I want to write toolkit code (GTK, Qt, ect) in a language that has to be run in a virtual machine? The point of writing shit small and fast is so they don't overuse your system resources. Why should something relatively simple like animating a widget interaction take 80% of your processing power? I can't believe someone marked this drivel up to 3 as interesting.
