Snow Leopard & a tid bit on Windows7

[harmonicgrunt]

ps3/360 do it best☺

[stevensonrf]

Thanks for this excellent video. You cleared up a few of the questions i had regrading the differences between Grand Central and Open CL.

[0m3n1337]

btw, good video mrbit, I liked how you took a really open minded approach.

[strickmans]

can u send me a ativirus

[demover7]

I just pre ordered snow leopard and im looking at a bunch of videos to really look at what i bought lol, your video did the best justice. i would just like to know is it worth it to upgrade it to SL because i saw on cnet that times for apps are slower? im kinda confused.

[mrbit10]

yea quite a few 32 bit apps can under perform and actually use more memory than need be. it is a result of running 32 on 64

[nitro912gr]

it is pretty cheap to get the SL, so why you worry? 30$ for the older versions 10$ for leopard, it is almost a give away.

[demover7]

its not the cost whatsoever its just the fact of weather its a better os. which i believe it is soo ehhh w/e.

[sacredgeometry]

snow leopard and 7 both impress the hell out of me. I am glad that they decided to improve the things that matter in these os instead of trying to just throw pointless toys at you.

i will use and buy both (i have allready preordered snow leopard) and install both on all my machines

peace

I had oportunity to use Snow Leopard and Window 7 retail install into Mac mini 2009 model. Supprisingly, both OS felt very similar and very simple and fast respond. Snow Leopard do boot up faster + sleep + awake about 10 second faster than window 7. Window 7 does improve on all those quality but not as fast a Snow leopard.

[tincho81]

First i have to say that i'm biased towards OS X. I think it's the best OS ever, far from any other.

I was going to say something, then when i finished watching the video i changed my mind. I think this is the way Apple manages challenges compared to MS.

Apple thinks ahead and thinks in the final user and the developer. They think of doing things simpler, rather than patching and patching and patching, like MS does.

[tincho81]

I don't know if it's b/c of my bias, but I find everything very tidy and organized in OS X, even when I program. Xcode is the best! And with GCD it will be tidy to program with threads (i have a little bit of experience using OpenMP on linux) and hence more efficient. Even if it's not efficient at the beggining it will be easier to fix since it's all centralized in GCD.

When I knew about the new features on Snow Leopard, i was very happy I switched to apple.

[0m3n1337]

@tincho81

Microsoft has had multi core management for quite some time. Microsoft is patching all of their operating systems so developers can take advantage of multicore technologies on all OSs.

[tenshitaiakuma]

running windows seven (build 7260, not RC 7100)

[Zectari]

Thanks for the video, I learned a lot :)

[iharrison30]

Outstanding video mate, I normally have problems following some of your more technical videos, HOWEVER that is due to my lack of intelligence and nothing to do with your videos. In this video I totally followed everything you mentioned and in fact enlightened me regarding Grand Central and Opencl. All the best mate and take care

[mrbit10]

thanks very much, I appreciate it!!!

[dev21a]

dude, r u a programmer? That's a little more than id ever care to know. I think it's pretty awsome that u know that stuff and can make vids like this. gratz on the video! 5star

[mrbit10]

yes i am a programmer going on 15 years now, thanks very much for the comment! :)

[Wiiman138]

What apps did u make?

[Physhi]

Mr Bit, you look so much better clean shaven, just so you know. I bet your waifu agrees with me. Even though it's completely, completely irrelevant to this entire video.

[mrbit10]

lol, my wife is the reason i have it. I used to have one years ago and hated it as it itched a lot but she asked for it again, and so i grew it out and will see how long it lasts. :)

[big46uk]

There are not much of an upgrade for the end users, since all these technologies are mainly for developers. Even OpenCL sounds good but if no app make use of it hmmm I think most people won't see the different between leopard and snow. I wonder if all the Intel mac does support OpenCL?

[mrbit10]

true, if the apps are not written for it, you do not get the benefit.

[jacofreak]

I remember reading somewhere about 20% faster video encoding under Snow Leopard. I think it was somewhere on Mac Rumors, but I can't seem to locate the thread right now. If I remember correctly they were saying that OpenCL may have been the cause of the increase.

[mrbit10]

just remember the application has to be written for it in order for it to use it

[stellarola]

I just wanted to give a shout out to you, mrbit10. Your videos are always very insightful and you're very aware of how tech works. This video was the reason I subscribed to you. I was going to make a similar video just to put to rest the misconceptions of how opencl and grand central work. Thanks and keep the videos coming! :)

[mrbit10]

thank you very much :)

[phishgroove]

have you tried snow leopard yet? doesnt sound like you have because I have and it's BLAZING fast.  the native apps all use GCD and the code is streamed lined. I don't care what MS does, it's slower than leopard and thats a fact....lol

[blacksteel25]

as long as you use "good" apps it is rare to screw up the registry. - ASCII808

This is true especially well known apps. A bad install or uninstall are the common causes of registry errors. It is far less common no to have these errors than when using Win 95, 98, or Me.

[thebsdguy]

Windows has had the System Restore feature as a safety net since Me - in case an install goes haywire and screws up your registry, you simply roll back.

[blacksteel25]

@ thebsdguy

Yeah, I know and Win Me really needed that System restore. I used to turn off System Restore, but I stopped doing it and instead just lowered it to 3%. System Restore has saved me a lot of headaches so I keep it on as a backup measure. Well not that I constantly screw up my computer, it's just good to have. Surprisingly not many people know about System Restore or forget about it.

[therevivedone]

Interesting, thanks for another great video!

[mrbit10]

thanks, always watching yours, love the reviews.

[christheferal]

Great video, took me 5 hours to load (no joke) - gotta love bandwidth restrictions.

[ljscott1990]

Why does 64 bit Windows based operating systems still have so many 32 bit applications, when they've been using 64 bit operating systems for years?

Do you think Mac will also be similar in this aspect, because most my applications in windows I see are installed to the program files (x86) folder.

Is it harder to integrate 64 bit coding into applications?

[mrbit10]

yes it may be the case, developers do what the deem is the correct path which may be influenced by price, time and etc. I hope not because the features beyond 64bit would not get used.

[thebsdguy]

Most of the binaries INCLUDED with Windows x64 editions are 64-bit. Things such as Internet Explorer include 32-bit binaries for the sake of compatibility with 32-bit plugins.

A lot of applications are being distributed with 64-bit binaries, but for many developers, the burden of compiling, debugging, and testing 64-bit binaries on top of their 32-bit binaries is too much work.

[ManBearPig90000]

Not to say i don't love your vids, because i do. but DUDE..... COME on. 17 minutes?

[christheferal]

People have the attention span of ants now :(

17 minutes isn't THAT long.

[Zenn3k]

Very informative. Thanks for the info :)

[mrbit10]

yea, i had one years ago but did not care for it, my wife loves it, thus it exists.

[ThingsontheWeb]

Bit10, your videos are always enlightening, I think Snow Leo will be a great upgrade. 64bit is not the future, it's NOW.

[christheferal]

pfft.. 64-bit... 128 bit pwns all over ur 64 bit.

Lol.

[garrettlove101]

great video. I really cant wait to upgrade to snow leopard!

[LucrativeFuture]

wow, turn down that intro please

[frvfilms]

do u ever talk about open source -gnu/linux?

[mrbit10]

i have discussed open source and linux what you like to see on the topic?

[chazybrewster]

your intro is too loud!

[Dylanv2123]

Yes, it is.

[kevinward]

i was just gunna say that

[mrbit10]

sorry it was done with a completely different program

[Oregu7]

MrBit, Thank you for another vid. Wicked intro!

[bamdadkhan]

okay, i'll repost my question from a while ago: does this mean that snow leopard will discontinue support for core solos (eg. mac mini)?

[mrbit10]

32 bit itnel chips will be supported but no multicore features will work with it.

[DRBUK]

whatever happens, no one will see any benefit unless those apps take advtange of the technologies.lol. same as 64 bit, issue, apps vs os

[DRBUK]

oh and i made the comment without watchign rest of the video, so u may have answered this later.lol. sorry

[DRBUK]

to me, if wat u said holds, sounds like a big misconception, about grand central...but then why would betrand salet (i know spelt wrong) say that grand central offers more system resources when an applicatino is idle, is he just saying that for developers to develop apps to take advantage of grand central dispatch, and that apple have NOT made apps to take advantage of that, e.g. mail which was also the example used at wwdc with regards to more system resources when an app is idle ? lol

[AppleSoldier]

SL does handle multi processing better than leopard. Its been improved across the board. Its not just GC, as big a part of it as it is.

[mrbit10]

Grand Central specifically is a programmatic way of taking locks and thread management off of the app and giving it to the OS. It is separate specifically from multiprocessing improvements. In other words, Apple made improvements and Grand Central takes advantage of them, BUT apps cannot use GC unless written to do so.

[AppleSoldier]

SL handles multicores different than Leopard because of grand central.

[AppleSoldier]

Modo is completely multi-threaded. When rendering with an 8 core mac, the new ones. You get 16 render buckets.

[mrbit10]

well, do not think of grand central as the improvement in mutlicores it is designed to take the burden off of the app and give it to the OS via programming. The apps you mention are multithreaded but will only take advantage of any improvements made in multiprocessing. To use grand central, they must be written to do so.

[JehxOne]

so in all of this

how the hell did vista drop the ball

[ASCII808]

I wonder how ati stream and cuda will hold up to grand central dispatch, time will tell I guess.

[carlheanerd]

You make Grand Central sound like a service or AI director imbedded into Snow Leopard. I always had the impression that Grand Central was a tool set or set of API's to assist developers with their multi-core programming. Really, what is Grand Central?

Also, I had a chance to play with Snow Leopard in it's earlier builds, and it increased my multi-core benchmarks by ~15% without any special programing. I like the no-hassle improvements!

[Atheismrulez]

Lol, what happened at the end? Did something fall?

[douguk47]

Thanks very much for a great video. Because of grand central do you see a new line line of quad core macs coming out across the range.

[TalesOfWar]

I can't see that for a small while. The most I can see having quads would be the iMac (not including the Mac Pro here). iMacs use mobile CPU's, so unless they're happy to increase power use and so on then Quads may be a while away. At least until the Nahalem based i7 Mobile CPU's coming at the end of the year, which apparently come in Quad models. Time will tell!

[mrbit10]

that has to do more with price of the chip and what apple deems the consumer will pay for.

[niceveritt18]

Loving the tash.

[blacksteel25]

The one thing I would like to see is a built in registry cleaner for Win 7 and it would save the registry entry of the file that will be uninstalled. I know there is already software out there that does it, but I'd like to have it built in. Perhaps MS can't because of EU and anti-trust getting on their case.

[ThingsontheWeb]

YES ... blacksteel25 ... I have nothing to add ... I completely agree with you.

[blacksteel25]

Congratz on your 100th video Mrbit.

If your looking for a subject for a video. I may have one, "The Windows Registry" what's the pro's and con's of it. People constantly point out that it's a bad thing and causes problems, yet I haven't seen a problem with it since Win 98.

[oOTheAlchemistOo]

I concur, also OpenGL vs Direct X what's the difference.

[ASCII808]

its not the registry itself, its the applications that screw up the registry. the people that have registry problems use bad shareware or bad software in general. I think Windows should have a built in registry cleaner to make sure it does not get bloated/fragmented. usually the apps the make your computer slow down are applications that require tons of registry access like business programs like quicken,etc. its very rare for the registry to screw up on its on.

[ASCII808]

"own"

[TalesOfWar]

Most of the software that leaves the registry messy in my experience is Microsoft stuff. At least of the applications I use.

[AppleSoldier]

all apps clog up the registry on windows

[AppleSoldier]

modo 401 will be 64bit

[thebsdguy]

FUD

[mrbit10]

?????

[thebsdguy]

I was referring to some of emeek's comments

[AppleSoldier]

Very Rare to screw up? LOLOLOLOLOLOLOLOLOLL

[ASCII808]

as long as you use "good" apps it is rare to screw up the registry. don't tell me that Macs can not slow down overtime. haha yeah that is right you blocked me because of that lol.

[matthew376]

Nice to see another "bit" from you! I agree with blacksteel25 - the Windows Registry would definitely make a good topic of discussion!

[Sven88abc]

Here another yes! to the subject blacksteel25 proposed. I would really like to know about the Windows registry. How does it work, is Mac OS X using something similar, etc.

Great vid btw!

[AppleSoldier]

no it uses nothing similar. OSX has NO registry.

[daly154]

Has Photoshop got a 64 bit version for Mac?. If not, would Snow Leopard encourage Adobe to develop a 64 bit version.

[mrbit10]

absolutely.

[timmis15]

Do you know whats new in Snow Leopard, because it all looks the same to me.

[mrbit10]

it is more of what is under the hood than the paint job if you will.

[timmis15]

What's the biggest difference between Leopard & Snow Leopard i guess i was trying to say & will it make Windows 7 run for it's money.

[mrbit10]

Yes Grand Central has its syntax to create markers to block a code ready for a queue, I am not aware of MS having the same thing in design. MS has fibers and such and allows you to block code but you have to use locks and such.

[roger767]

its Mr Bit from the evil universe (goatee beard)

[JehxOne]

i know I was thinking that too
