Reviewers like Matt Grommes are the reason I know most reviews suck, because he does it so well. (writing sucky reviews.)
His review reads like a high school dork literary snob wannabe looking for something profound in his utterly lacking life. i pity u. perhaps you'll grow out of it one day.
Your opinion comes from a "glass half full/half empty" perspective, which you can't really address.
What you should be asking is why is it so difficult to write bug free code? The obvious answer is because developing and testing code is harder than you realize. A simple if statement looping 10 times will have over 1000 different code paths that you would need to test if you wanted to be thorough. So a large software project makes this kind of testing impossible.
What people try to do instead is use Paredo's 80/20 rule. Basically, you try and focus on a few modules that generate the majority of bugs. There are many other methods of testing, but none are 100% and any significant project will have errors. Unfortunate, but a fact of life. People are not perfect.
Why aren't there more Compact Flash based MP3 players out there?!! Currently I'm using a 1GB Sandisk card with my NexIIe player.
I spent 60 for the player, 200 for the flash.
Advantages: -No moving parts. The hard drive based Rio I had would overheat and act funny, drain battery fast, and crash during the winter. Primary use is in the car/hostile temps. Flash based player has no problems. -low power consumption. runs on 2 AA batteries for 14 hours! I use a bunch of rechargeable NiMH batts. Convenient as hell. No worries about proprietary and expensive lithium ion battery dying. -larger capacities and lower prices all the time. Compare that to smartmedia or whatever.
I like my NexIIe, but c'mon. I'd like to see alot more players with better build quality. Let's see some competition.
Binary logic would have no problems working on a Ternary computer. You guys are confusing the hardware and software layers.
You can kind of think of DNA as a quaternary data format. ATCG for each base position in a codon. 01 for binary. 012 for ternary.
One of the problems for designing a ternary computer is designing cheap circuits that could reliably switch and maintain 3 states. The voltage tolerances are tougher compared to the binary all or nothing approach. (be it 0 or +5V or something.)
Wasn't Betamax a proprietary standard from Sony which demanded royalties? Regardless of whether it may or may not have been technically better, to hell with it.
They should make an opensource hi def DVD standard that is patent/royalty free and get on with it.
There was a Pop Up VH1 episode where they did Tom Petty's "Mary Jane's Last Dance". I think he was a mortician acting out a necrophiliac like fantasy. Anyway one of the pop up facts said something to the effect about how corpses today stay "fresh" longer because of all the preservatives and chemicals in our food. If this is true, this can't be good.
How do we know if 3DR isn't just waiting for people to forget about DNF? Maybe development has completely stopped and they're just hoping the publisher will just go away and suffer their losses.
Perhaps after seeing how Daikatana went, they'd rather be a no show and cut their losses early with zero publicity. Then take a nice vacation with the $12 million advance from the publisher. If they were smart, they already did this when they went into silent mode back in 2002.

I used to own a 42" Plasma (Panny EDTV 848x480 $4000). However, had I known how good projectors were nowadays, I would never would have bought it.
Currently I own a Sanyo PLV-70 ($4,500 1366x768) with a 105" Dalite HiPower screen ($350). And it's almost like a 105" plasma!
HDTV looks awesome. And DVD's look pretty good too. Finding Nemo is one of the best looking ones so far... But the hardware really needs Hi Definition material to shine. 480 just don't cut it at that size. Hollywood needs to get their butt in gear.
And with a DVI input, I've connected my computer and played Unreal2, MotoGP2, Vice City, etc. at 16:9 widescreen at 1360x768. Sick!
And you can do email, surf the web and everything with the 3D gyro mouse and keypad. Completely useable as a computer screen.:)
I can only hope Half Life 2 and Doom 3 properly support widescreen.
And if you ever decide to move, the PJ weighs about 20lbs. Compare that to a 90lb plasma that's fragile as hell, or a giant rear projection system.
Bulbls are expensive, at around $400. But totally worth it as it'll last me at least a year. No plasma burn in fears.
If I had to do it again I would get a screen no larger than 80" as everything but HDTV material looks crappy at 105". DVD's, cable TV, etc just don't have enough resolution. Can't wait for WM9 and other HD material... and maybe there will be an affordable native 1920x1080 projector by then.:)
In the meantime, I think I'll go pickup Max Payne 2 and MS Flight Simulator and play them in HD.:)

Probably because the US felt they deserved it. Probably because it's easier to kill people who are a different race from you like the Japs as opposed to the Germs. Probably because it would make a great test of their new weapons. Probably because they happened to have two on hand. Probably to unambiguously establish that their immediate unconditional surrender would not result in their total destruction. The strike fierce, strike hard mentality.
I noticed that the Red vs Blue files are 360x240. Are there files that will allow us to watch using the native engine? Imagine being able to turn up the detail/graphics.
I remember Operation Bayshield for Quake allowed me to up the resolution. Nice and crisp. 360x240 is bleh.
There are two ways to design a chess engine. One is to use brute force with hardware like Deep Blue. The other is to use a heuristic approach relying on advanced/intelligent algorithms.
The right algorithms can achieve a performance many orders of magnitude greater than that achievable with hardware even with Moore's law.
And the wrong algorithm can bring any computer to a slow and hugely inefficient crawl.

After setting up an HDTV system, DVD quality is barely acceptable to me now! And divx is especially worse. DVD is the 640x480 of monitor resolutions. HDTV is like running at 1600x1200 or 1024x768... sorta. But at 16:9!
DETAILS HAVE EMERGED of the future design of Intel's Cajones/Pentium 6 processor, and of how the chip firm will present it to the world.
The chip will sample internally at Intel in January 2006 and will take between four to six months to get to market. The Pentium 6 will follow a very similar schedule.
The Pentium V is likely to fly along at between 50GHz to 60GHz, have 6MB plus of level two cache, be built on a 60 nanometer process, and have a stackable design.!
I'm annoyed by how this gets modded as insightful when it seems that most of the people posting quickly attack the technology without trying to understand how Prevayler achieves ACID compliance.
It may not replace most databases today, but don't be so shortsighted. Your dismissive remarks sound like early comments on Linux. The hardware landscape will be quite different with the advent of ubiquitous 64bit+ systems in the years to come.
Anyway, here's a link that sheds some light on transactions.
http://www.prevayler.org/wiki.jsp?topic=Rollback Is Needless
-------------------- I'm still trying to wrap my head around object prevalence, but it seems to me that it's the previous comment's assumptions that are invalid. In an RDBMS each select, insert, update, etc. is a single atomic command, thus you need to use explicit transactions to group several operations in an atomic way. And in a prevalent system (to quote Klaus), "Only one command is executed on a prevalent system at a time." What I'm thinking (someone correct me if I'm wrong) is that executing a (synchronized) command in a prevalent system might be a call to a single method which contains all needed business logic and does (or doesn't do, or undoes, or...) data modifications as appropriate.
Unless you're talking about using transactions with ad-hoc queries, in which case it's more an issue of how to handle ad-hoc queries (discussed elsewhere) than how to handle transactions.
- Joel Fouse
So if I understand this correctly, every single ACID transaction that a particular system requires gets implemented as one of these Prevayler command objects, and these objects are globally synchronised (ie. only one of them can execute at once). This would enforce globally serialised access to your "data model", and hence eliminate a lot of the concurrency related problems that traditional RDBMS transactions attempt to solve. In a traditional database, global serialisation would guarantee truly abysmal performance, but I'm guessing that because everything happens in memory, this isn't an issue with Prevayler?
If I've got it right, that makes a fair bit of sense actually......although I must admit that I'm not particularly satisfied with the answers that have been given for some of the issues that others have raised. In particular:
1. 2PC (in the case where your transactional boundary encompasses more than just your PrevLayer? "data model")
2. rollback support (to avoid having to manually guarantee ALL preconditions BEFORE modifying any of the "data model" objects)
etc.
-- Peter Monks
You are right regarding the speed of globally synchronized transactions in RAM (Instantaneous Transactions) and the fact that this eliminates concurrency problems among them. Before they are executed serially, mind you, they are written to disk in parallel. Prevayler 1.03 does that, although that was not yet migrated to the 2.0 architecture.
As for 2PC see Two Phase Commit Is Unnecessary.
As for not being able to guarantee all preconditions for your transactions, please keep a secret: thanks to coding by Jon Tirsen, Prevayler 2.0 will actually only execute transactions which are guaranteed not to throw Runtime Exceptions! If a transaction would throw a Runtime Exception, Prevayler just does not execute it on your system. "How on earth does Prevayler know wether a particular transaction would throw a Runtime Exception?" Download the 2.0 code from CVS and try it out. It is pretty cool to see that working and, as most of Prevayler, is based on an anticlimactically simple idea brought up by several people on the Prevayler Team.
