This is not true at all. Multi-threading often introduces more problems such as race conditions, deadlocks, pipeline starvations, memory leaks, cache coherency problems. Further more, multithreaded apps are harder and take longer to debug. Also, using threads without good reason too is not efficient (context swtiching) and can cause problems (thread priorities) with other apps running. This is because threads can not yield to other threads and block if such an undesirable condition like a deadlock exists.. Like on Windows when one app has a non responsive thread and the whole system hangs.. Or like when Finder sucks and locks everything..
Yes, yes, all true... Somewhat. True in the sense of how a lot of programmers approach current threading problems and various development theories. And we're currently limited by our development tools and the operating systems to a certain degree.
Also, multithreading behaves differently on different platforms with different language environments. Java threading might behave differently than p-threads (C-based) on the same system (OS X).. I am a prfessional developer etc..
Yes, but so many things behave differently from one platform to another. How is writing a low-level thread management system for each platform different than writing the core functions of a 3D graphics engine that can run cross-platform and take advantage of various differences or feature - OpenGL, Direct3D, 3DNow, etc.. Cross-platform development always has its issues as do using different development tools. You obviously know this as do many programmers, so what's the point of the doom and gloom? It's always been this way and is just a part of the development process.
Massively multithreaded apps do exist and have been written for various platforms over the years. Here in Windows and OSX land programmers go into panic mode when multithreading is mentioned. Yet SGI had Irix scaled to 256 CPUs and visulization apps utilizing multithreading on individual systems as well as across cluster nodes and displaying images built by multiple graphics pipes using multithreaded OpenGL that could scale from 1 to 16 graphics pipes and any number of CPUs.
Anyway, my whole point is that the software industry will eventually have to tackle this problem head on and will overcome it. I just don't understand the current resistance and denial exhibited by so many "developers". The hardware is coming, in many situations it's already here... Why fight it? It's time to look at threads in a new light (for many). Upcoming CPU roadmaps place newer quad-core chips in the market in mid '07 with common Xeon and Opteron workstations/servers moving to quad-CPU (16-core) with 45nm process and lower wattage. 8-core CPUs to arrive in '08, 12 and 16 cores per CPU in late '08 or early '09...
MHz isn't increasing and the consumer still wants the next version of their game or video editor to run twice as fast with more features on the new stystem they just bought, which now has 32 cores instead of 18 cores and they'll switch to a competitor's product if you take more than two or three months to ship your software update... What do you do?

Our Founding Fathers believed in God, proof alone is the pledge of allegiance "under god". Yes our country was founded on christian belief. Hate to say it, but it's true!
As for the invisible man in the sky I have no clue to what you are referring.
If you're in the service I can only suggest you avail yourself of the educational opportunities that are available. Many of the Founders were not "Christian," and a belief in God is no proof of a "Christian" belief system.
The United States was not founded as a "Christian" nation. I'd suggest you review the free exercise and establishment clauses of the First Amendment, as well as the history surrounding the settlement of what we often refer to as the original 13 colonies.

The Future of video games?
In the future, your controller will cost �400, require a 10ft HDMI cable, a �25 adapter, and have the graphics of a PS2.
Yeah, and you can unplug it, put it in your bag, play it on the train, surf the web, check your email, edit your movie ...bit more than a $400 controller

I don't see any reason any manufacture would cripple their own storage capacity when they obviously have other options. If its no for the first generation of discs and players, then coroporate rigmroll is the reason to blame for HD-DVD winning out because that is just STUPID.
I agree. It's really stupid.
If Blu-ray studios authored their discs in VC-1 and DD+ or TruHD... the whole HD DVD picture/sound "advantage" would be moot. But they are not. (At least, not yet anyway.)
One possibility is that they are just trying to rush stuff out the door (to counter HD DVD's time advantage), and it's easier/faster to author in MPEG2 (with existing tools). At least they can say "we have product out there", even though that product sucks.
But apparently not wanting to use a Microsoft codec is another.

We probably won't see a Core 2 Mini until but that just fine for me because that's when the Intel GMA X3000 will be ready.
UPDATE:
It looks like the GMA X3000 is ready to go now, but a Yonah coupled with a X3000 IGP would still make the Mini a great machine.

I much prefer the US style (a first for me! :D), and will probably hope to buy a new computer before I leave for this specific reason. For example, what is with the tiny UK return key?
I am so with you. It's almost the main reason why I want my next Apple (MMBP, obviously) to come from the US. The narrow vertical return key is a PoS. The $$$ saving over ��� is almost secondary! ;)

I've been waiting for my 17 inch macbook pro for months now, and it's finnaly due to arrive on Monday. (Getting it from UK to South Africa without it getting stolen is a big problem I've had)
So I'll be gutted if they release new one, but I'm working on the old 1ghz G4 powerbook, so I'm going to be flying anyway! With or without the extra odd 20% speed of the core2 duo.....
Perhaps there will be the case re-design though, that would be nice.

^yeah almost seems unfair to ppl that want to compete but dont have access to high end hardware. i guess if you look at it from an aggregate standpoint then low point crunchers make a bit of a diff.
the amount of power sucked from the wall per unit would be WAY less i would imagine. from an environmental standpoint it wouldnt make sense
That's why I dropped the G5 after I saw how little it was doing against the Mac Pro and even the low end amd's, it just wasn't worth it in terms of the electric bill.
And speaking of electric bills... I'm just kind of guessing here but I think folding is costing me about $50 a month :eek:

The US could have sat this one out and it would not affect your pension or your healthcare. The cost of this UN mission is spread among all 10 nations and the freezing of Gaddafi's assets.
If the UN continued to ignore the people of Libya asking for the International community to step in ... Gaddafi would force the people to comply to him with deadly force.
IMO this will be a quick victory for the UN and the Libyan people ... Gaddafi can go live with Mubarak.
It's just the last time I remember a UN action it was 98% US in Iraq.

It looks very cool and I'm impressed by the 1080p video. I didn't think there was enough video memory to do that.
The iPad + HDMI adapter looks a little awkward though. I think a cooler solution would be to have bluetooth controller support, like PS3 controllers or maybe even use the iPhone for the controller via bluetooth.
Either way, it's impressive. Not quite Xbox 360/PS3 but definitely better than the Wii.

Along with the macbook and MB pro getting updates, for $14.95 you can download an ipod nano or ipod patch/software that lets you listen to FM radio without having to purchase the radio remote. Interface is the same as with the remote.
Cool beans. Where can you get this download?

Previous question: How hard could it be to take advangate of the multi-cores.
The first thing is that it depends on what you are starting with. If you have zero code out there, you can come up with a nice design for your program that takes advantage of as many cores as you throw at it. If on the other hand you have large chunks of legacy code that was written in the time of single cores, it may be close to a re-write to fully take advantage of the hardware. In some cases it will be easier in some cases to throw the old code away.
But some of it is imagination, if you can look at a problem and the solution you orginaly came up with, and using your imagination look at the problem at hand in inovative ways, parts of the programs could be re-written to take advantage of the hardware and other parts can be left alone (for the short term). This is an incremental step, you gain X% in one area and little to nothing in another area. The key is to determine what your program spends most of it time doing and re-write/re-design that section of the code for the biggest short-term gains.
I remeber working in assembler and selecting the correct combination of instructions based on their function and the number of CPU cycles it took to execute each instruction. Sometimes a set of 12 instructions was faster than a different set of 8 instructions in accomplishing the same result. Use your imagination and look at the problem from a different angle. If your brain only sees a number of serialized steps, you won't be able to come up with anything that takes advange of the hardware.
What you start with (old code) and your imagination can get you there quicker or slower.
Short answer: It depends.

I work with these machines on the daily. Their service manuals are three mouse clicks and the type of my password away. My co-worker has at least two of them bare naked chips and bits exposed and all at his bench on the daily. It's hard not to stare at them as I take my morning walk to the break room to grab a cup of water. I can speak definitively because I know what I'm talking about. As for pompousness, sorry my tone offends you. Perhaps you might try ignoring it?

agreed, although I don't think I'd ever pay more than $9.99... I'd rather just buy the DVD.

Hey, thank you for being an idiot !! I wasn't replying because I went on Holidays. I went to see Tokyo for Five days and track down the old places of Edo described in Ernest Satow's 1921 book "A diplomat in Japan" and to buy a new Emac !! Its 115 000 yen in Japan for a Superdrive model. Oh, I forgot...For you being a high school graduate - Edo (or Yedo in some translations) is the old name of Tokyo. Up until the Meiji restoration.
If I was stupid - I wouldn't speak two languages
If I was an ignorant person - I would have stayed in my home country and not learn about the ways of the world...I believe that you have spent too much time in front of you mac.
If I was a vain pretender to knowledge - Do you know who Ernest Satow was ? Do you know over 2,000 Japanese kanji characters ? Do you know how to live in another country ? You have NO IDEA
So please don't call other people names - This is a thread for discussion not a primary school (If you are American - a primary school is a elementary school) :D
i'm sorry, this has got to be one of the most irrelevant comments i've read here at MR.
(btw, not to brag or anything, but i'll one up you: i speak japanese and english, both fluently. i've lived (not just traveled) in japan, USA and switzerland. i also have a phd in physics. what does all that have to do with having a constructive discussion? NOTHING.)
