[opensuse] New desktop
Hi It's time to find me a new machine for home office and related work. But what is the best choice right now? It's a tough one. I need to balance the requirements and make choices like - 32 or 64? - Motherboard - Disks - Graphics adapter - Low consumption vs performance Anyone has any input to this? Any sites that can help me with the configuration, any do-it-yourself sites? Or irc channels where this is discussed? -- Med venlig hilsen Kaare Rasmussen, Jasonic Jasonic Telefon: +45 3816 2582 Nordre Fasanvej 12 2000 Frederiksberg Email: kaare@jasonic.dk -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

- 32 or 64? If you are buying secondhand or very low down, this question could be discussed, otherwise 64bit is what you get.
- Motherboard Depends on your needs. I would suggest to buy one that is already on the market for a few monthes and thus, you do not get the exact latest and greatest but rather get information about bugs, performance and Linux compatibility
- Disks That depends on your needs in regard to size and sound intensity
- Graphics adapter For Linux, I woulkd currently choose Nvidia. The model depends on your needs
- Low consumption vs performance Can't comment on this one, my knowledge is not sufficent.
One missing thing in your list imho: How silent will your computer need to be and what will you be able to spend for silence?
Anyone has any input to this? Any sites that can help me with the configuration, any do-it-yourself sites?

Aren't there still problems with some applications, plugins for Firefox, binary drivers for graphics adapters? :

It depends on how you define problems. You can run a complete 32bit install of openSUSE on a 64 bit system and it works without any issues. You can also run a complete 64 bit install of openSUSE... but... this may be where you have heard of problems. Certain plugins and media codecs are only available in 32 bit. This means you have to install and run some 32 bit libraries and applications if you are running a 64 bit install. It is possible, and depending on your needs may or may not be a problem for you. There is no harm (and barely any significant performance difference for most general computer use in my experience) to install a 32bit Linux install on a 64 bit computer... and then no issues with 32bit codecs, and certain 32bit binary drivers that and even applications you may want to use.

And in fact, in my experience, just the added pain and hassle of trying to work out how to get the 32-bit plugins to work on a 64-bit install just added to my decision that 32-bit is the way to go. I never noticed any particular application (or even the underlying OS) running any faster as 64-bit (and believe me, I was trying to do so in order to justify the pain of getting everything running correctly). -- Casey Stamper http://www.stampersite.com/wordpress -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I understood the OP's question to be about the hardware that he will buy to build his desktop from. In regard to software, imho for a desktop it does not matter. I had good experiences with both Lin 32bit and Lin 64bit on 64bit hardware. However my experience with win 64bit software will make me recommend win32bit software for 64bit hardware. But: I never had the privilege to test win 64bit server software.
How silent will your computer need to be and what will you be able to spend for silence?
That is very important, agreed.
Imho, for a desktop nowadays, it comes very close to be the most important consideration since it is the machine's noisiness that either supports or distracts my mental attention. kind regards Eberhard

Doesn't it (mostly) come down to CPU heat production? (And btw. which 64 bit CPU is using least power)? -- Med venlig hilsen Kaare Rasmussen, Jasonic Jasonic Telefon: +45 3816 2582 Nordre Fasanvej 12 2000 Frederiksberg Email: kaare@jasonic.dk -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The size of the case will affect fan requirements. A small case will require more fans and large fans can be quieter for the same airflow. Also, the choise of disk drives can affect noise levels too. Even case colour can make a difference. A black case will radiate more heat, reducing the load on the fans. Since on some systems fans are controlled by temperature, this will reduce noise. -- Use OpenOffice.org <http://www.openoffice.org> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

CPU heat production: This is only part of the problem and generally the easiest one to rectify by buying a good cpu cooler with a very large (and therefore slow and quiet) fan.. The other major noise source is usually your GPU(s) and there is also your powersupply-fan(s) and eventually your harddisk(s) and optical drive(s), if you are unlucky you may also find one case fan or more. CPU power consumption
From hardware magazines I think I understand that AMD currently only has a slight power consumption advantage when the machine is idle. At any other machine state, Intel consumes less.
Well, imho it is debatable, whether a desktop does spend by far most of its life idling around. At the same time, AMD currently cannot beat Intel performancewise. Now, as I understand it, within a given CPU brand the lowest model usually consumes the least power and there are "special versions" of cpus around that consume even less. For me privately, I always go for AMD nevertheless since they are cheaper and performance is not an issue for me these days, since all of them (Intel and AMD) have far more horsepower than I can possibly use..
From my perspective, A good start for reading on the subject could be this: http://www.silentpcreview.com/

Can you elaborate a little more on this? I just recently installed 10.2 64-bit on a Sun Ultra 40 (dual amd 246 chips). I can install the i586 version of firefox, but it can't get it to talk to the network at all. It's as if I don't even have a plumbed ethernet interface.

As long as we're reminiscing here, I must jump in with this: In 1981 I bought the Big Board CPM computer, which came as a kit of components, with no peripherals. I found a 10" monitor and a keyboard from someplace that had a shift key, but only produced upper-case keycodes. It must have been used with a teletype machine or something similar. Not being a programmer, certainly not in assembler, I built (with some trial and error, since I'm also not a digital but an RF engineer) a converter out of TTL logic to produce both upper and lower case characters under control of the shift key. The Big Board would take parallel keyboard input, as well as serial, so this was not too difficult to do. (Genuine serial k/b's usually only came as part of a terminal, which was pretty darned expensive back in the day.) In another aside, I found, with the help of another engineer who was experienced in video, that the BB was deficient in video bandwidth, so I figured out how to cure that, and wrote it up for the Micro-Cornucopia. They sent me a Tee-shirt, which I still have, marked "AUTHOR". --doug -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Incidentally, many years ago, I bought a huge Cherry keyboard, without any encoder logic. I designed & built my own encoder and used that keyboard with my IMSAI 8080.

That Cherry keyboard was unique. The standard keyboard keys had white key tops and all the other keys, function, number pad etc., had gray tops. There were almost as many gray as white keys. That keyboard was wired as two separate keyboards, each with it's own scanning matrix, in one physical package. The white keys were one keyboard and the gray keys the other. My encoder combined the two into one big keyboard, with the 8th bit used to signify which set of keys was in use. I used a 2716 EPROM to convert the scan codes to ASCII and I included auto repeat etc. It worked well. Some time after that, I was taking a digital logics course at Ryerson, in Toronto. One of the projects was to build a hex keyboard. I just showed the instructor what I had designed & built and that was good enough to get full marks for the project. ;-) BTW, the only reason I took that course, was because it was a compulsory prerequisite for some other courses I wanted to take. There wasn't much I actually learned in it, though it was fun to play with the Commodore CBM we used to connect to some projects. I also became an "assistant instructor", helping the other students with their projects. -- Use OpenOffice.org <http://www.openoffice.org> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
As regards silence, the old IBM keyboards are absolutely the most wonderful and loud keyboards in existance. Some electronics/computer/ham-radio fleamarkets have these. If noise is no object, get one! They seem to last forever. No Windows keys, but you probably wouldn't care.
I swear by my Cherry Linux Keyboard :-) http://www.cherrycorp.com/english/cymotion-line/cymotion-line_master_linux.h... The keys think and rattle in a nice traditional way. Ha. And... no Windows key.. they've replaced it with a nice penguin key. C -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi
One missing thing in your list imho: How silent will your computer need to be and what will you be able to spend for silence?
Anyone has any input to this? Any sites that can help me with the configuration, any do-it-yourself sites?

Fully agreed!!!! Although I confess being a silent PC geek and there is hardly anything that nerves me more than noisy PCs that I must work with for hours , this does not apply to keyboards. This is typed on a Model M style keyboard with 122 keys that I got from ebay for 10€. Looks like this http://www.shoppalstores.com/ibmmodelm/image//2002021-004.jpg Unfortunately not all keys work with a PC, but all I need and much more is there. This one is also suitable for self-defence and in case you need a hammer but do not one, you do not need to buy one. They are great, they are even greater when your PC is silent and they are greatest when there is no one else in the room who is constantly complaining about your IBM klicky-keyboard noise. ;-) Lately I found a solution to the latter problem and bought my wife another Model M. Now we are both on Klickey-Keyboard, she never wants to use anything else keyboardwise and most important, we are in love, once again. ;-)) regards Eberhard -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The pictured keyboard is apparently a foreign version. I'm using 2 model Ms on my computers, and all the keys work with Linux or Windows, except probably the Scroll Lock, Print Screen, and Pause keys that I've never seen work on anything. My American model M's do not have any keys left of the Tab, Caps- Lock, Shift, Ctrl. And the bottom left alpha key is Z. --doug, wa2say

Well, with Model M interchangeable keycaps foreign versions do not matter so much, you can always replace the keycaps with what is correct for your language. Mine is actually a 122 Keys Model (much larger and heavier) with 24 Functionkeys that was meant to be used with an AS/400 Console. And this is the reason, not all Keys generate a keycode on a PC which you can then (re)map according to your needs. Eberhard
