Broadcom Releases Source For Graphics Stack; Raspberry Pi Sets Bounty For Port

xynopsis Not open-source but another RPC layer! (77 comments)

Unfortunately, if you look at the "driver sources" carefully, it's just another shim to the real driver that does the heavy lifting. This implementation does not submit GPU instructions directly nor does it expose the shader compiler where someone can trace how shaders are being transformed into native instructions. In the end, it's just a layer that just submits user data to some specialized (probably proprietary) ioctl that exposes the functionality of the real driver implemented as a binary kernel blob and/or microcode running on the firmware.

See https://github.com/raspberrypi/userland/blob/master/interface/khronos/glxx/glxx_client.c for example.

Haswell Integrated Graphics Promise 2-3X Performance Boost

xynopsis Re:Now intel users can play 10 year old games :D (133 comments)

Honestly unless you are playing Crisis they are getting pretty good. I played Portal 2 on IGP. That is two years old, but the laptop I played on was already a year old at that point.

New Intel IGPs does handle Crysis with fluid framerates even with quality settings turned high.

Intel Challenges ARM On Power Consumption... And Ties

xynopsis Re:Intel GPUs more open prospect than ARM (163 comments)

You either don't know what you're talking about or just plainly trolling. The GPU specs that Intel opened is the CoreHD graphics series which is Intel's own GPU technology and is in no way related to ImgTech's PowerVR.

I am looking forward though to the real competition between ARM's latest and greatest with Intel's upcoming Haswell.

WD Builds High-Capacity, Helium-Filled HDDs

xynopsis Re:Why not a vacuum (356 comments)

Hard drive heads ride on a cusion of air (or in this case, a gas of some kind) so that they don't crash against the drive.

Why a gas? Why not float it using an electromagnet instead?

Ask Slashdot: How Would You Fix the Linux Desktop?

xynopsis Re:It's not broken. (1154 comments)

- Create a desktop kernel fork. Linus & co. are not in the business of writing/maintaining a desktop kernel. Their goals are larger (and smaller) than that. The desktop kernel can track the mainline kernel, but shouldn't adopt every latest ABI or other changeâ"just do a major update every 3-5 years.

What on earth would that achieve? And what is the difference between a "desktop kernel" and a "server kernel" or whatever.

One glaring example of this is the kernel scheduler. If you ever used the OSX / IOS notice how smooth the graphics is and well responding it is to touch events even under heavy load compared to Linux desktops / Android. Although there have been much improvements done in Linux recently especially Android stack that smoothes the UI experience, occasionally you will still encounter random hiccups in the UI (even with a quad-core CPU). Same is true with other Linux-based such as the Nokia N9 Harmattan, where although the graphics is pretty much smooth, the user sometimes encounters stuttering when swiping or scrolling windows.

As the GP pointed out, part of the problem here is that the Linux kernel have vested interests towards server infrastructures. The current scheduler, CFS (tries to) balances CPU utilization and user interactivity fairly. If Linux were to achieve a more smoother response we need a scheduler for extremely low latencies instead of fair prioritization.

There is a project to change the scheduler towards this low latency approach, but even the project author is not expecting it to be accepted in mainline soon - the reason why we need a fork.

Next Mars Mission Selected For Funding

xynopsis NASA rejected the other riskier bets... (61 comments)

...but insanely exciting missions: a robotic boat that would have floated on a methane lake on Saturn’s moon Titan and a comet explorer. I would prefer the robotic boat. You never know what lurks beneath those lakes (TMAs?). This is unfortunate though. Seems NASA has mastered the technical hurdles of Mars but rested on its laurels instead, sticking to tried and true approaches.

Digia to acquire Qt from Nokia

xynopsis This has been expected (1 comments)

Yet another result of Elop's mismanagement of a once great organization. Qt would have been the platform that powered the next generation smartphones to low budget featurephones. Too bad Qt wasn't given a chance due to this guy's ties with his former employer.

I just wished instead the old Trolltech would rise again.

'Wearable Computing Will Be the Norm,' Says Google Glass Team

xynopsis Nokia was first with this idea (196 comments)

I once saw this concept videovideo at Nokia Research Centre in Helsinki more than 3 years ago. Too bad Nokia failed to capitalise it on time and now they are failing big time.

Nokia Introduces MeeGo-Powered N9 Phone

xynopsis Re:Impressive, but sluggish (252 comments)

Seems? How can you say it is sluggish you haven't even tried it out personally? Or were you just judging the performance based on the videos. I have the prototype and it is extrememely fast and snappy indeed. Even Engadget which is biased towards Apple is impressed

KDE SC 4.7 May Use OpenGL 3 For Compositing

xynopsis Nothing special about this (187 comments)

Just the need to upgrade how Kwin uses OpenGL currently to do rendering. Right now its still using the old OpenGL 1.1 - style rendering (fixed-function rendering pipeline) to a programmable one using vertex and fragment shaders. This way, it'll be easier to port it on embedded devices that uses OpenGL 2.0 by default

What Are the Best Valentine's Day Stunts?

xynopsis no geeky girls please! (470 comments)

I shudder to think of capturing the interest of geeky girls! No more geeky girls for me. When they like you, they tend to like you in a crazy manner! I had the experience of one trying to get my attention in every way. She would always try to understand the software projects that I am working on and even google the terminologies that I put in my blog. This is funny, but she asked me out lots of times, I tried to say no but is really persistent. She once caught me having dinner with friends in restaurant and in a very planned manner, went straight to our table talked to a couple of my friends behind my back and then went to me. She tends to approach love and relationships in a very calculated manner. I am already like that and NO I am not going to spend my life with a person who is just like me (why can't I attract the real girls)? :/

Who Wants To Be a Billionaire Coder?

xynopsis Re:Who needs to be a billionaire? (318 comments)

From what you are describing, it seems that you hate your workplace/work unfortunately. Still, that is not a reason that fun and work couldn't go together. I am only required to work 37.5 hours / week but still I go the office on Saturdays sometimes because I can't wait to finish that code that I have been working on Friday. Oh, I have a great office: quiet, cool, designer furniture, big glass windows, and a nice view of the sea. And I feel the sense of satisfaction that my code is going to be part of the lives of billions of people around the world. Money is really just the icing on the cake (disclaimer: I work for one of the largest corporations in the world).

xynopsis Re:Just Don't Try This... (273 comments)

True. There are cases where working on a secure office is absolutely a must. For example if you're writing embedded code for prototype hardware that your company doesn't want competitors to know about. How are you going to do just that in a coffee shop?

Google Earth Recreates Ancient Rome

xynopsis I was there last week (97 comments)

I just went to visit the ruins of ancient Rome last week! I didn't like the smell of candles and old churches though. I also almost got stuck in the place because of the Alitalia strike. Virtual tours should be better solution for those planning to go there physically :)

xynopsis xynopsis writes  |  about 2 years ago

xynopsis (224788) writes "Looks like the final version of the Linux based Steam Gaming Console has been made public at CES. The result of combined efforts of small-form-factor maker Xi3 and Valve, the gaming box named 'Piston' is a potential game changer in transforming the Linux desktop and gaming market. The pretty device looks like a shrunk Tezro from Silicon Graphics when SGI used to be cool."

Mystery Illness After Meteorite Crash

xynopsis xynopsis writes  |  more than 7 years ago

xynopsis (224788) writes "Villagers in southern Peru were struck by a mysterious illness after a meteorite made a fiery crash to Earth in their area, regional authorities said Monday. Residents complained of headaches and vomiting brought on by a "strange odor," local health department official Jorge Lopez told Peruvian radio RPP. Seven policemen who went to check on the reports also became ill and had to be given oxygen before being hospitalized."
