32 bit vs 64 bit?

Re: 32 bit vs 64 bit?

As Adobe has now raised 64-bit Flash from the dead after seven months and finally released a new 64-bit flash version, the last reason why some didn't want to use 64-bit dissolved into thin air

You can install the 64-bit Flash plugin by simply adding the following repository:
https://launchpad.net/~sevenmachines/+archive/flash

Packages are avaiable for Karmic, Lucid and Maverick.

hey, thanks for this link, 64 bit flash kicks backside. flash pages (flash games especially) load like 10 times faster now.

Re: 32 bit vs 64 bit?

The PAE kernel is specifically for 32 bit hardware so that it can use more than 3GB of RAM. So, if you use on on your 4GB RAM box it will be able to use all of the RAM.

You know, if I ever run out of stuff to do maybe I'll give 32- and 64-bit a try side by side. Kubuntu install takes about ten minutes off a USB drive - and the installation wouldn't have to be much. If I did it with mencoder I wouldn't even need a DE and the test would be a little more fair.

32-bit server kernels have PAE enabled, yes?

I will say that my netbook and the 64-bit desktop PC have an almost identical software load and the 64-bit box uses more than twice the RAM at idle that the netbook does. That in itself isn't a problem except for the disk time to load a bigger application.

I believe that is correct. But, see EnablingPAE

Hmmm. Apparently Lucid desktop versions install a PAE kernel if they detect more than 3GB RAM. Thanks, Snowhog

Re: 32 bit vs 64 bit?

Due to its architecture, it's *impossible* for 32-bit to use more than 3GB of Ram.

Not true, you are free to cook your own kernel so that even a 32-bit OS can see more than 3GB.

"No true" yourself :P A 32-bit system *cannot* go past 3 GB. With the pae kernel, it can only move its 3 GB window around by using lots of swapping to see other parts of the memory. It can then add up the adresses of these windows to calculate how much memory is installed.

But honestly, what is the point these days? As GG says, problems are few and far between, I've never had one even though I do have that horrible thing called skype on my box which exists only as a 32-bit app. Simply install the 32-bit libs (Kubuntu probably does it by default anyway) and you won't even notice it. 64-bit is the future, nuff said

Yes, there's absolutely *no* point in using 32-bit anymore.

Except if that is all the hardware you can afford. I support some of elderly folks on limited retirement incomes whose only access to computers are the 32 bit boxes that folks throw away as as they buy newer replacements. They Some retireees can't afford the $299 netbooks. I accept donated oldies & goldies and then put Kubuntu or Puppy on them, along with Skype, and buy webcams (usually the Logitech C2xxx uvc series) for them, then give them to folks who need an internet connection but can't afford a new computer. So far, the oldest working computer I recently rehabilitated and gave to an immigrant was a 12 year old Toshiba. 32 bit boxes aren't being made any more, afaik, but many were so well made that they are still good, despite being underpowered when compared to the modern dual core notebooks.

and a solid 32bit linux OS is just what these old boxes need to be usable again.

YES!, and I especially like the price-point and the "EULA"

You're a good man GG; a good man.

I don't care how many times people stamp and shout that 64 bit flash is as functional as 32 bit - its *not*

Yesterday for the nth time I installed a 64 bit machine (Maverick) and youtube was quite broken. Couldn't see video at all. Various other flash heavy sites were just as problematic, often causing a crash in nspluginviewer. On the same PC booted with 32bit Maverick flash works fine.

I've seen this replicated 100% on various different 64 bit real and virtual machines, I've never seen it work right.

*However* - Using the new Adobe Flash 64 beta - released just last thursday things are much improved. I have 64 bit flash working under rekonq 0.60 and its been pretty reliable so far.

That's because you weren't using the 64-bit Flash there but instead 32-bit Flash with nspluginwrapper, which is just utter garbage.

Of course, native 64-bit Flash doesn't have any problems. The 64-bit Flash plugin they had out before (and killed off in february) always had worked fine for me as well.

Re: 32 bit vs 64 bit?

I kept using the discontinued 64 bit version after the shutdown, and never had any problems with it. I have the tarball saved. I have now installed the new one and I am not having any problems with it.

Re: 32 bit vs 64 bit?

I just installed the sevenmachines ppa and 64 bit flash and it's working better than the older version for me.

Same here, also kept using the old 64-bit version after Adobe killed it. Using nspluginwrapper is only for masochists.
No problems with the new version here either.

Late to the party. This is more than a year old, things should be even better now that more folks optmized their code for 64 bits:
