nearly any other CPU architecture running at 6GHz will muder the P4's performance in either integer or float-point, partially due to Prescott's insanely long 31-stage pipeline and relatively week parallelism
also, the P4 excels only in programs so small it can fit in the really small L1 cache. AMD's L1 cache is the really juicy one. =)
Intel designed the Pentium 4 solely around marketing's requirements of consumer hype instead of sound technical choices.
the physical speed limitations of hard drives (sustained read/write, not SATA) is the real wimpy part of the bandwidth....
when running multi-gigabyte SQL queries (at work, our entire RDBMS is about 1TB), the crawling speeds of the hard drive is evident. the time it takes to develop the SQL query and the time it takes to run it are comparable (btw, the queries are okay optimized)
6GHz might be useful for 3D rendering jobs or obsessive gamers, but for the bulk of the business world, the HDD is still the pain in the a**
> Turns out the market was more interested in backwards compatibility.
Sun was trying to leverage this by having EVERY freaking SPARC being backward compatible to the good ol' PDP-7 days....then the SPARC bloats and bloats until today's UltraSPARC - a red giant waiting for gravitational collapse (sigh)
although, i feel that Sun Microsystems now is more like a black hole...they suck customers inward, and once u've fell through the event horizon (i.e. making a purchase), u'll never see daylight again...
i totally agree.....Gmail was put out to beta simply to hype up the IPO price...
let's see....
other than searching, Orkut was too exclusive (invite-only) to reach critical mass (such as friendster), Froogle can't remotely compare to pricegrabber, and Gmail is at best equal to offerings by YahooMail and Hotmail. Meanwhile, Yahoo or MSN provides a complete portal. (I personally use MyYahoo to provide a one-stop portal for email subject lines, headline news, weather, customized stock portfolio, calendar, movie showtimes of cinemas near my home, mileage accumulation on various airlines, and daily comic strips.)
just like Internet Explorer using NCSA Mosaic code, slapping your GUI onto a pre-built browser engine is not what innovation stands for (read : Firefox/Opera).
Google is excellent on unstructured web searching, no doubt about that. But seriously, stick to what they KNOW!
hey no one is forcing you to buy an ipod mini or rio carbon here....if u think the price is articial, go get a low-cost "market-priced" 256MB flash-based one.
luxury items are never meant to be priced based on market demand. look at diamonds, louis vuitton, or bentley. they have every reason to over-charge you for the design, the quality, and the prestige of possessing a status symbol.
i work around wall st, and nearly every banker-looking person has the iPod. on wall st, if you're using other mp3 products, u're already a second-class citizen.
The customization of Symbian OS for P900 is nearly perfect by all accounts. It feels like a phone but with powerful PDA functionality. MP3, video, touch screen, J2ME...you name it. Althought I think the UI on it has a bit too many colors, making it a bit fancy for those who prefer the simplicity of Palm OS (okay, PalmOS default GUI is rather plain). One thing though - the camera should be megapixel with flash and digital zoom (or better, optical). Symbian did a great job on the P900 and the Nokia 6600 because it's so flexible to each manufacturer's specification. I'd hate to see the OS becoming Nokia centric (very stable, but on the lagging edge of new features). My last point can be shown by how long it took Nokia to release a phone with a 65K color screen, a resolution better than 128x128, and omni-Bluetooth-presence. Also, the 8910i being dual-band does nothing to help expand its market share to the high-end executives in USA and Canada who have to settle with lessor products by Motorola....
If Nokia can make all their medium and high end phones Series 60 (symbian based), that'll be good. Series 40 is nice but way too slow (comparable to T68i speed...imagine...) And I think Samsung

Sprint PCS also uses CDMA in the PCS band (1900). Nowadays, AT&T and T-Mobile offers GPRS. Cingular has GPRS+EDGE. Sprint has 1xRTT. And Verizon has 1xEV-DO. And Nextel gives you nothing other than an expensive walkie-talkie and a phone that's 2 inches THICK.
here at Cornell University, instead of blocking P2P or port scanning, they came up with a nice little schema to defeat ALL internet traffic - charge dorm access by the MEGABYTE !!!! You're only allowed 2GB of non-intranet traffic per month, which is like NOTHING. Just keeping AIM in the background while browsing a few sites already can take up 2 GB. Solution? Do all large downloading at computer lab, and use a USB flash drive to bring it home. Not only this kills p2p, but it kills Internet access as a whole. So great, CIT!
I am an ugrad CS at Cornell, and I can tell you that only ONE of our CS course is taught is C# (CS 215). Reason : Because we also have Intro to C (113) and Intro to C++ (213) courses. CS215 is OPTIONAL for all CS majors. However, the REQUIRED core :
100-211-212
are all taught in Java. Our Database course is taught in C++, Networking course in Java, Compiler course in Java, OS course in C.
FYI : Ugrad and Grad combined, we have over 100 CS courses. Only one of those are taught in C#.
SMP is hardly the "latest and greatest". SMP in OpenBSD is LONG over-due. Can't believe it took Theo THAT LONG to sort out his priorities. If OpenBSD wants it's security to do some useful work, they need to on a SMP system these days. How frequently do you still here "corporate mission-critical server with single CPU" today?
What density? Hong Kong is as dense as New York, yet we have coverage in all subway, throughout the harbor, and in every building and nearly every ELEVATOR in the buildings. Given enough cell towers, we can overcome the wavelenght issue. It's only when u try to put up 1 cell tower to cover Broadway, then the signal degenerates indoor.
USA's urban coverage is one of the worst amomg developed nations. Emphasize the urban part, since good rural coverage is unrealistic anyway. One of the major reaons was that USA can't agree on one standard. You can have 3 cell towers in Broadway, but one on TDMA, one on CDMA, and one on GSM, so effectively u only get 1/3rd the signal of the entire cell infrastructure, which somewhat explains why there are over 100 million cell phone subscribers in USA, and the coverage is still so bad.
Also, since USA doesn't use GSM, u can't just switch by changing your SIM card...u have to change your phone. Therefore the companies each essentially has a guaranteed subscriber base, and has no incentive to improve coverage or enter price wars.
In Hong Kong there are 6 carriers, and you can actually transfer your cell number when you switch carriers. Now that's true competition which benefits the customer. By the way, did I mention that there are nearly same number of registered phone numbers as the population. That's what defines a commodity. Cell phones, like land-line phones, should be a commodity not a prestige. In Hong Kong the pricing of cell airtime is comparable to land lines, and you actually pay less if you chat infrequently than a land-line, so many single people abandoned home-line phone altogether in favor of a cell. Apparently, USA is nothing close to that.
Notice how countries with successful cell phone service are ones that can agree on a single standard (UK - GSM, Korea - CDMA, Japan - PHS...), and notice how no CDMA phone companies (such as Verizon and Sprint) even bother to adversise international roaming....cause they can't! (your fingers and toes can count all the countries that use CDMA, while there are more than 160 countries on GSM...you do the math). [By the way, T-Mobile USA offers $1/min roaming in Western Europe (long dist free)]
Has anyone noticed that Dell's A5, like most other PPC devices out there, contains nearly no product differentiation. They only differ by CPU and RAM, and some devices have identical specs.
Product differentiation is key to broad audience acceptance. Sony Clie's are popular because they have regular (T) and clamshell designs (NR/NX). Nokia phones are popular because their designs differ, on top of specs. Notice how most Samsung and LG phones are clamshell design, which immediate removed it's appeal from half the people who prefer candy-bar style phones.
One huge win for the voice of many against the new evil empire (read : RIAA). Now, if only my university could stand up against RIAA instead of harassing their students regarding "copyright" crap by some fscking Tr8cy M1tr8n0 (IT Lawyer), then RIAA would loose their battle forever.
Agreed, since SQL is not Turing-complete. There's no point in proposing a non-Turing-complete language as the best programming language, since u can't even do everything u want.
If I were there I would've submitted an entry using SML (the functional lang taught at Cornell), since ML has one of the most elegant syntax out there. Pattern-matching and strong typing is what makes ML such a great language. I'd wish I knew OCaml, but SML suffices for now.
If one wants a built-in library that does everything, then Java is the way to go (just look at the number of classes offered in JDK). You can nearly do everything in C++ compared to C, so I don't see good reasons why someone should still be using C extensively (okay, low-level programming, but doesn't C++ makes it easier for the programmer?)
I was surprised someone submitted an entry with Ruby, one person typed "Perl" as "Pearl", and so few Scheme submissions compared to LISP and ML.

just because i'm anti-Gmail then I'm labelled as a Microsoft employee? i don't even work in the software industry...
besides, i would choose Yahoo or MSN/Hotmail's comprehensive user-welcoming portals instead of subscribing to Google's elitist ideologies
so i have to download yet another desktop gmail client, only to have to wait perpetually for someone to send me a gmail-invite.
i'll choose solid 100MB from Yahoo over a gig of vaporware from Gmail, thank you very much.

Palm and Sony has been in this market long enough to know what's good. Toshiba is a new comer. Leave it at that.
Does the PocketPC have keyboards? No. Clie = Yes.
If PocketPC is so good, why did it take MS so many years, and still haven't even achieved 1/3 market share?
