  1. Re:Don't run modern software on old hardware on Negroponte says Linux too 'Fat' · · Score: 1

    Think about it: 20 years ago, computer science taught you to write good programs in relatively low-level languages; now they teach you to program in languages like Java with virtually no regard for efficiency. Programs could be written much, much more efficiently, and most of what we use today could easily be made to run on hardware over ten years old if more effort was put into optimizing it.

    20 years ago we weren't doing what we do now with computers. Pull out a word processor from 20 years ago and tell me that it looks like a "good program" today.

    More to the point, Java isn't slow! In many cases, it even beats C++.

    My cellphone runs what is probably the closest thing to a production Java OS that exists today. The Danger Hiptop runs an entire OS on top of a Java VM, and while certain key functions are written in assembly (graphics functions, mostly), the OS manages to fare remarkably well considering that it's running on a 24MHz ARM with 4MB of memory. Neither Palm OS, nor Windows CE, nor embedded Linux would run as well on a system that is so limited.

    the programmers take up every ounce of system resources they can now by being lazy

    That's quite frankly crap. I remember a time when PCs struggled to play MP3s and run a word processor at the same time. Now I have no trouble playing a DVD while streaming media accross the network and recording two channels of TV.

    None of the software on my system is "taking up every ounce of system resources". Right now, I'm using 4% of my CPU and have over 800MB of free physical memory (which is being used for disk cache at the moment). Is my PC high-end? Not in the least. I have an Athlon 64 2800+ system with 1GB of DDR400 running Windows XP.

    and most of what we use today could easily be made to run on hardware over ten years old if more effort was put into optimizing it

    A GPU from ten years ago wouldn't even be able to run today's games, let alone at a decent framerate. Forget about encoding XVID captures of DVDs, either - look at this chart (the bottom one) and note that a $150 2.4GHz Athlon 64 "Newcastle" does in 2 minutes what takes the fastest CPU from 10 years ago (the Pentium MMX 233, which is actually only 8.5 years old) 20 times as long.

    Remember how problematic it used to be to print a large document? Remember how long PDF files took to open? Remember how long it used to take Flash animations to load? Remember how crappy video used to look?

    The problem with people like you is that you forget what it was really like just 15 years ago. Mac OS was a dog on the computers of 1991, as was Windows. HP-UX took minutes to boot up. Even 10 years ago, the only reason that we didn't notice how slowly webpages rendered was because most of us were using modems. Pull out a copy of Netscape 2.0 and an old 68040 Mac to run it on, then tell me that we're not doing better. Fire up Word 7.0 on a 33MHz 486 with 16MB of memory and Windows 95, then tell me that applications aren't faster today.

    Microsoft Word starts in 3 seconds on my system. Less if it's disk cached. I can resize it without a wireframe mode because the system is fast enough to redraw the application as I resize it.

    Software uses more memory today because it does more. No one would think of working with 50MB photographs in 1996. No one would think about editing DV footage without expensive hardware.

    If you think MySQL is all you ever need database-wise, I humbly suggest you rethink your competence in the field.

    Or perhaps you're not in the field at all. There are really three classes of databases today:
    • Enterprise-Class databases (e.g. Teradata, Oracle 10g)
    • Business-Class databases (e.g. Postgres, MSSQL)
    • Lightweight databases (e.g. MySQL, SQLite)


    Now, of course, there's a ton of overlap here. As MySQL becomes more feature-rich, it begins to enter the "business-class"; MSSQL is beginning to see some success in the "enterprise class" as well.

    The bottom line is simple: you're not going to run your bank's accounting system on MySQL, but you're not going to run a PHP forum on Oracle either.

    What a database is has changed - thanks to the Internet, we are now using databases for applications that were never though of before. If you think that MySQL is all you'll ever need, you may very well be right - most people will never need the kinds of features that Oracle offers. Of course, if all you think you'll ever need is MySQL, you're not a DBA and you probably won't be hiring one anytime soon.

    I always found the Slashdot attitude about graphics to be strange - more of a reaction against the common wisdom than anything really thought out. Every time a new NVIDIA card comes out, there are 200 comments about how it's unnecessary. About how the old card was just fine.

    Let me say this - graphics are important. Of course gameplay is more important, but there's no reason that we can't have both. I want a system that can push an HDTV. I want a system that can push loads of special effects and maintain a constant 60fps. I want more realistic characters, larger environments, and smarter AI.

    The Gamecube is a fine system. I one one myself. When the Revolution ships, I'll probably get one - I like the idea of playing 20 years of games on a system. I think that the controller will be cool, and while I'm not sure if it will be practical, I'm willing to bet taht the Big-N will come up with some cool applications. But I do not for a second believe that the Revolution is a replacement for the XBOX 360 or the PS3. I'm glad that Microsoft and Sony are pushing graphics forward. And I'm disappointed that Nintendo isn't doing the same. Having an affordable system is important, but why is the Revolution limited to 83MB of memory? How much does 256M of DRAM really cost? And why can't it output at least 480p? Even my Gamecube could output 480p.

    It's looking more and more like the Revolution is just an updated Gamecube. But by the time the Revolution ships, the 'Cube will be more than 5 years old. Can't Nintendo do a little better?

  18. Re:How about a checksum digit in phone numbers? on Homemade Cell Phone Call Blocker? · · Score: 1

    The other problem here is the crazy North American idea of having cell phone numbers in the same area codes as landlines, but requiring the receiver to pay for incoming calls. If all mobile providers were on their own recognizable area codes, and the caller knew that calling a mobile number was expensive, there'd be a lot fewer of these wrong numbers.

    The advantage of this, of course, is that it costs the same to call a landline as it does to call a cellphone. In Europe, for example, it generally costs more to call a cellphone.

    Also, if you compare per-minute rates, we still pay less for cellular service, even when you consider that the call is billed twice (once for each party).

    Your solution of "make cellphones more expensive to call" does nothing. Few people intentionally misdial a call, and when you consider that in the future, most calls will be to cellphones, misdialed calls will continue to be a problem for some time.

    Of course, many of us don't have this problem - I have recieved perhaps one misdialed call on my cell in the past 3 months. Certain numbers, however, are more vulnerable to digit transposition and other common mistakes - particularly considering that numbers are not assigned in a uniform manner.

Even a single query rarely produces a results page under 32K (add it up), which, added to the homepage views, means that Google is transferring over 9.6TB per day in searches alone.

    Because, as you know, 148GB of data transfer per day costs so much. 2000GB of data transfer runs around $40-$100, depending on who you buy it from, and Google certainly pays much less than we would. Even assuming the high figure, that works out to around $8 per day.

    I'm pretty sure Google can afford $8 per day. The W3C abuse isn't for bandwidth concerns. It may help the page load a little faster on slow connections, but even on a modem, 2KB of extra data only takes a second to load. Especially if you have GZIP compression enabled on the server side.

    No, you're not. Vista is late, very late. Microsoft didn't have clear goals on what to do after Windows XP - at first, there was very little to put into Longhorn and it was going to be essentially a Windows ME type upgrade. Sometime in 2003, however, Microsoft dramatically changed course as they realized that security was a real problem in Windows XP. In 2004, development started over (using the Windows Server 2003 codebase), and Microsoft esentially threw away what they had been working on for the last three years.

    As the project grew in scope, Microsoft promised more than they could deliver. What we're seeing now is a natural part of any project - when you realize that you can't meet all of your goals and you have to decide what's really important.

    If you want to know what's really going on with Vista, download one of the CTPs (from Microsoft Connect or MSDN - downloading it from BitTorrent is illegal). You'll find an OS that is full of bugs but also full of promise. You begin to look at what you know about Windows, and you discover that Vista is - in many ways - an entirely different OS. Then you fire up Steam and play Half-Life 2, and you realize that it's still Windows.

    Every CTP has had better hardware support, better performance, better stability, more features, and more polish than the previous CTP. Assuming that this continues until October, Vista might just be a success after all.
