udrepper: Memory and Cache Paper

Excellent paper on memory and cache from a programmer’s point of view. It still surprises how little most programmers know about the hardware they are programming on. Thanks for the great paper Ulrich, it is bound to improve the quality of code out there.

You can download it but do not re-publish it or make it available in any form to others. I do not want multiple copies flying around, at least not while I’m still intending to maintain the document. With Jonathan Corbet’s help the text should actually be readable. I had to change some of the text in the end to accommodate line breaks in the PDF. So I might have introduced problems, don’t think bad about Jonathan’s abilities. Aside, this is a large document. You simply go blind after a while, I know I do. Which brings me to the next point. Even though I intend to maintain the document, don’t expect me to do much in the near future. I’ve been working on it for far too long now and need a break. Integrating all the editing Jonathan produced plus today’s line breaking have given me the re [From udrepper: Memory and Cache Paper]

It can’t be easy to improve upon a $37,000, 39 megapixel DSLR, but high-end camera manufacturer Hasselblad claims to have done just that with its H3DII-39MS, which adds a multi-shot feature (and $7,000) to the recently-announced H3DII-39 (pictured). Targeted at architectural and still-life photographers, the 39MS essentially takes its sibling’s body and tacks on Hasselblad’s CF-39MS digital back, promising unprecedented performance and image quality when firing off multiple shots in sequence. Look for this new model in stores (specialty retailers, not Best Buy) starting in January of next year.

Switched from Firefox to Opera

I have finally had enough with the all the memory leaks of Firefox and have switched to Opera.I have been a long timer Firefox user, since the really early days, but lately the memory bloat has just increased beyond what is comfortable…. The worst part of the experience though is that Firefox will sometimes lock up all the tabs while it is trying to connect to some ad site or doing garbage collection.I switched to Opera a week ago, and after a small transition period I am no really happy with it, It is always responsive, does not use much memory and has this most awesome feature called Speed dial.

I have been a long timer Firefox user, since the really early days, but lately the memory bloat has just increased beyond what is comfortable. My browser is sometimes running for weeks at a time and it is not unnatural to see Firefox reach the 800MB mark even though I might only have 2 tabs open. The consequence of this is that the rest of my programs, xemacs mail iChat and Serendipity Blackmagic become unresponsive for a few seconds as I switch over to them. The worst part of the experience though is that Firefox will sometimes lock up all the tabs while it is trying to connect to some ad site or doing garbage collection.
