GNU/Linux Running On An 8-Bit Processor

uiuyhn8i8 slow? (361 comments)

I dream of a CPU that fast. :) When developing our new CPUs we run them in RTL-simulators. At a realtime speed of about 100Hz. Yes, no Kilo and no Mega. Herz is what we got. Linux takes about a month to boot to init at that speed. After removing the (at 100Hz) almost eternal bogomips loop that is... Needless to say Linux is a useless ancient behemoth at that speed so we write our own OS for running in simulator.

Apple Intern Spent 12 Weeks Porting Mac OS X To ARM

uiuyhn8i8 Re:Apple history (368 comments)

>And considering an intern could port a complete OS port in a mere 12 weeks, shows how portable it is.

Yeah. It's called unix. As long as you have the proper C-compiler for your cpu it's not hard to port a unix-like OS to another CPU. We did this fifteen years ago for one of our CPUs. Actually was an intern who did that to. It's kind of compile, look-at-compile-error, fix, redo and finally when you got it running fix the CPU config errors and the few low-level stack handling errors you've done. Apart from the do-it-once configuration of MMUs, caches, etc it's not really that much magic to a CPU from on OS point of view.

The Ugly State of ARM Support On Linux

uiuyhn8i8 Re:AMEN (94 comments)

>Anything even moderately complex would require driver code, not just descriptive data.

Our chips with 3K pages of documentation and no driver code disagrees. And they run linux in millions of products. It really depends on the quality of the documentation. Which is generally pretty bad for mosts chips I have looked at.

>But they should standardise. There's no advantage to the user, >the OEM, or the OS developers in having so many different SoCs.

So you don't want any technical development? Or you think that ARM in a monopoly situation will still develop the core functionality at the same pace as all other chip design companies?

Microsoft Patents GPU-Accelerated Video Encoding

uiuyhn8i8 Repeat after me, PATENT = CLAIMS (304 comments)

Man, it is tiring to have to explain this to the slashdot drones every time one of these stupid patent stories comes up.

THE PATENT ONLY PATENTS WHAT IS WRITTEN IN THE _CLAIMS_ IN THE PATENT. NOT THE TITLE OF THE PATENT. NOT THE ABSTRACT. NOT THE DESCRIPTION. NOT THE STUPID SLASHDOT STORY. ONLY THE CLAIMS.

For this patent that means if you implement this ideas EXACTLY AS IN THE 39 CLAIMS except for, for example '7. The method as recited in claim 6, wherein the pixel offset includes a range of 1 to 16 pixels.' and your pixel offset is 17, you are cool. You are fucking golden. Gedit? So quit your whining about previous art until you find something that follows THE CLAIMS. OK? THE FUCKING CLAIMS!!!!!!!

Hunters Shot Down Google Fiber

Also expect it to read the minds of the troopers and gather statistics of how to best show them commercials directly in their brains, for the benefit of the soap and tootphaste companies.

Why Broadband Prices Haven't Decreased

uiuyhn8i8 Moore's law (336 comments)

>After a new technology is introduced to the market, there is usually a predictable decrease in price as it becomes more common. Not to defend the broadband providers in any way, but electronics get cheaper because of Moore's law on transistors and lower cost if you produce big volumes. This does not apply to ditches and cables. The biggest reason that you don't get cheaper broadband in USA is of course that you have elected senators that are bribed by the companies.

Best Way To Archive Emails For Later Searching?

uiuyhn8i8 Re:mbox + grep (385 comments)

>How is this 'funny'? That's how I've archived 15 years worth of email. Really.

I don't understand the funny mod either. Even though I think I might be even more lo-tech. All outgoing mail for the last 15 years are concateneted to a plain text file (cause that's what rmail in emacs does) and old incoming mail is in a emacs rmail file (also plain text). With less, grep and some shell or perl oneliners I can search 2GB faster than all the gui-clickers.

IBM Unveils Fastest Microprocessor Ever

uiuyhn8i8 Re:This chip snickers at my 6502... (292 comments)

>Can't even imagine writing in assembly code for this monster. I miss dinking around with a nice 6502 system. To each his own. I kinda agree though. I also grew up on hand coding machine code on the 6502 and it sure was fun, and educational. But now working on designing 32-bit embedded chips I feel really comfortable with a couple of hundreds of instructions instead of ~60. And I sure wouldn't want to do anyhing more complex with the limited addressing modes on the 6502. And you will never see Linux on a 6502... Btw we actually designed a 6502 once and it used a couple of thousand gates, compared with a couple of billion in a high end CPU. Hard not to be impressed by the oldschool designs.

The varieties of grapes in those wines where, and are, the same regardless of in which country they are made.

Stop the Math Press's Presses — Knuth Announces iTex

uiuyhn8i8 Re:Perspective vs. Tunnel Vision (284 comments)

>All 27 users of TeX will be quite excited about this.

Funny. Personally I generate 3000 pages of technical documentation for our chips in about 20 seconds with latex. Secretaries and salesdrones can play with the wysiwyg toys, while we who need serious results for serious work use serious tools. Having spent the last week reading a lot of scientific papers it amazes even me that close to 100% of them are done in latex.

Zoho Don't Need No Stinking Ph.D. Programmers

uiuyhn8i8 not black and white (612 comments)

How about realising that it doesn't have to be either or? We have both well-educated aces and selftought aces at our company. Of course here in sweden the latter are much more rare as almost all intelligent people with interests in technology get a higher education, but they certainly do exist and it is a real shame if your company doesn't use them.

Modern Day Equivalent of Byte/Compute! Magazine?

uiuyhn8i8 Re:Circuit Cellar (327 comments)

>I really miss Byte :(

I totally agree. Having recycled my old Byte magazines I have gone to the University library and read through all issues of Byte. Twice. You get the entire computer history from the microcomputer onwards. And I swear there is magic in them there pages.

This reminds me of a long time ago when each issue of Byte had a card where you could fill in all the ads you were interested in and send in to Byte. They then forwarded this to all the companies and you actually got a boatload of brochures and stuff from them, often printed on really nice, thick, expensive luxuriant paper. They really wanted to do business with you. To bad for them I only was a twelve year old in Sweden who thought it would be fun with some brochures. No surprise they stopped doing that...

Simon Singh To Appeal In UK Court Today

uiuyhn8i8 chiropractice is medicine (213 comments)

If chiropractice is bogus or not of course depends on what they say they cure. I haven't checked every chiropractor here in sweden but generally they are definitely serious and fix real problems when for example discs in your back are out of alignment and nerves become pinched. They are part of the medical establishment. And as someone from a family with serious back problems I say thank good for swedish chiropractors. It's either bed-ridden with maximum dosage of morphine or going to a chiropractor to fix it.

Obama DOJ Sides With RIAA Again In Tenenbaum

uiuyhn8i8 Re:Hope and Change, baby! (528 comments)

Always funny to read how americans complain about how fundraising wrecks your democracy. Don't know if you know this over there in the USA, but in the civilized world (in my case sweden) it is not called fundraising, it is called bribery and is illegal. You understand? No company, private person or organization is allowed to give money or things or services to any politician. Nada. Zip. Because they are elected by the people and allowing bribery naturally wrecks the whole concept of democracy. Don't know why you put up with your trainwreck of political system, but nevermind, I'm sure there's some good on the telly between the commercials.

Programming With Proportional Fonts?

You are all a bunch of limp wristed weaklings with your god damn new yuppie fonts. Use '-misc-fixed-medium-*-*-*-14-*-*-*-c-*-*-*' and view your code as emacs and X11 intended it with hard, cold gloriously pixelated simplicity.

Mozilla Rolls Out Firefox 3.6 RC, Nears Final

uiuyhn8i8 Re:So what was the code from? (145 comments)

>running a pretty stable system, so it may be days or weeks

Jesus, I hope you are running windos or something if you consider weekly reboots stable. For the record, my Linux system practically never goes down. It's the power outages that takes it down perhaps once a year. Desktop machine that is. And I use a window manager that only manages windows (ctwm) and not the entire system, which I suspect is the reason it never dies. The servers are on UPS and are usually up for a couple of years before we upgrade redhat on them or upgrade hardware.
