In the small-ish world of open-source & embedded graphics, toolkits, and SW / HW rendering implementors, there are few who have been at it as long and have such a breadth / depth of experience in so many areas as yourself.

As someone who has done a fair bit of searching for resources on the theory and practical design of such systems, I must say, that there are few books out there that concisely describe the "how" and "why" in a design-patterns kind of way tie in with immediately relevant topics (e.g. fbdev, widget & drawing libs, scene-graphs). Naturally, implementors often pick up the talent and ensure that trade secret is kept that way, but you are at a bit of an advantage I think, no?

You've been at E for a *long* time and you've done an insane amount of work making SW rendering almost as efficient as HW rendering - I'm sure there is no shortage of material.

Have you ever thought about writing a book - sharing some of your expertise with the world in a less formal language? Not something that's all-encompassing by any means but maybe with references for further reading. What about a techno-biography of E?

The OpenSSL libraries in Android are in the /system partition, and hence, can be patched via OTA update. So yes, they are provided by the OS. And unless the API has changed for OpenSSL (likely not), all Android apps require no modification to be considered secure after said OTA update. Rather than attempting to discourage Android app developers, the linked article really should just be putting pressure on Google, OHA members, and carriers to release OTA updates that include a patch to OpenSSL.

cfriedt writes "After seemingly abandoning MeeGo, Nokia has now officially announced that Meego (Maemo Harmattan to developers) to will be powering the new Nokia N9. And it is not shy on design features according to the tech specs.

Could this be the final Linux-based offering from the Finnish giant as they transition to Windows Phone 7 products? Will the N9 retain the hacker-friendly policy of its Maemo predecessors?"

Back in 2007 when Asus came out with the first Eee PC it shipped with the Xandros distribution, but after Microsoft turned up with it's hacked down version of Windows, most netbook manufacturers dropped Linux in favour of Windows. Now Asus has said it will load Ubuntu on three of its Eee PC netbooks from 1 July 2011. Lets hope this will kickstart other netbook makers into preloading Linux onto their machines."

Submitted by timothy
timothy (36799) writes "Compared to their dumber e-ink cousins, tablets with LCD screens suffer at least two notable disadvantages: their batteries last hours or days, rather than weeks (or months), and they're notoriously hard to read in the sunshine. Neither of these problems are likely to be licked soon, but the gap may be shrinking: Mary Lou Jepsen's OLPC spinoff Pixel Qi has now shown off a 10", 1280x800 panel. Pixel Qi's screens are well-known, though not currently widely adopted, for their ability to run in a high-contrast, low-power greyscale mode as well as a still-frugal color mode. Though the company is currently showing prototypes rather than a shipping version of the new high-resolution screens, it's reason to renew hope for a long-lived, daylight-readable, color-screen tablet."

My first question would be about the power that board is consuming ddr3 support (800+ MT/s). Keep in mind that transistors sink the most amount of current (i.e. consume power) when they are in the process of switching from '0' to '1' and vice versa. So if The bus speed has just increased by at least a factor of 4, then power consumption might have increased proportionally. A think a performance-per-watt graph comparing the Exynos chip and a dual core atom is in order (ahem.... tom's ... cough... hardware... sniff).

My next question would be, "where are the Mali GPU drivers?" A free as in speech implementation of all patent unencumbered interfaces of this GPU would be brilliant. Can't wait to talk to the Linaro devs ;-)

Programming

+ - Tiny cores are here, and they change programming-> 3

Submitted by Anonymous Coward
An anonymous reader writes "Intel is returning to in-order cores after two decades with Atom and Knights. ARM is already building in-order cores for iPhones, iPads, and Androids. IBM has switched to in-order cores after building generations of out-of-order cores. This indicates a clear trend that in-order cores are back in the mainstream. Highlighting the performance characteristics of in-order and out-of-order cores, Dr. Aater Suleman's article explains why programming for in-order cores is very different from programming for the now-traditional out-of-order cores. Thus, this new trend requires a change in compilers, tools, and programming techniques. Compilers need to get better at removing useless code and instruction scheduling. Programmers need to weigh new trade-offs and perform classic optimizations that have been forgotten. I liked this article particularly for the very simple code examples and a simple explanation of in-order and out-of-order differences. The message is clear: programmers and compilers need to understand in-order cores and target their code better."

It's often ___immeasureably__ useful to get some (any) kind of console output when porting Linux to an existing device running e.g. windows mobile 5 or 6. Take a look at HaRET. Porting is often harder than most would imagine, as some manufacturers actively use hardware obfuscation methods to prevent hacktivists from getting console access.

Try to imagine how long it would take to use LEDs or haptic feedback to iteratively check all conditions required to bring up Linux on a board without a serial port. The first thing you would probably do is try to use a hardware subsystem that was known to work and fashion a serial port out of it. This is the same concept but graphical.

Great work!
