SGI wouldn't have been able to manage that business as well as Sun did; at least the E10K was successful somewhere.

I used Google Play Game Services for a turn-based Android game a friend and I made this summer[1]. I like to develop on the PC and have a really fast test cycle, so I made a client implementation for desktop Java using a wrapper around the

Interesting -- I thought someone with deep enough pockets could write their own DMP code for the IMVN part. I'm sure the Android Wear devices (which mostly use the MPU-6500) must use the DMP to detect when to power on (they can't

No, the lag is waiting for the rotation to stop before starting the animation. If the screen is on then the power drain from the accelerometer running as fast as it can is tiny anyway.

The Invensense has an autonomous mode (on Android devices it can count steps without bothering the host CPU) -- does the Bosch do this too? Apple have a separate Cortex-M3 which is branded as the "M7" or "M8" motion proc

Anecdotally, the Lightning cable seems to be a bit flaky itself, getting 1.5 stars from 1646 reviews on Apple's store: http://store.apple.com/us/product/MD818ZM/A/lightning-to-usb... Hopefully Type

Is the bug fixed in iOS 8? I didn't see where the page said that... The author has a reliable exploit for iOS 7.1.x, but that doesn't mean the bug was fixed (maybe other things moved around so the shellcode doesn't work?). I

I've spent ages in LightBlue poking at BLE devices. I had no idea there was also a hardware module, the "bean". It looks pretty nice: http://punchthrough.com/bean/ -- definitely a lot easier than manhand

Is the source for the app runtime available anywhere? I've done a bunch of hacking on the Android framework to do things like multitasking before, so I'm really curious to see how they "put Android in a box".

Hopefully the new Camera API in Android L makes this app possible -- you have much better control of the incoming frames with accurate timestamps, so matching them up to recorded gyroscope information and cropping/offsetting them befor

Because the layout that's presented is not native. Actual mac apps don't have tabs and toolbars pushed together like that, and the margins are different. wxWidgets can use the platform native controls, but the apps rarely look nat

In the bay area the bike lane becomes dashed at intersections meaning anyone can go anywhere. The disadvantage with going into the lane is that cars have much shorter stopping distances. I had an accident a few months ago where I had just m

Most right-hooks happen when the light is already green, not when starting from a stop. So imagine that the car and bike are moving at the same speed and the driver doesn't check their mirror or doesn't notice the bike before they

I saw it happen to someone two days ago crossing the Caltrain tracks and going over Alma on Meadow in Palo Alto. White van went past the cyclist and then turned right into him -- luckily he just hit his front wheel (though the van drove off

In Chrome (for me, on 64bit Linux) it consumes 176MB of RAM -- for all of WebKit + Cairo + FreeType/HarfBuzz/etc -- it's most of an OS right there. GMail, a webapp email reader, is currently taking 368MB of RAM. Insane!

That's cool; thanks for sharing. So you could use the accelerometer independently of the touchscreen for gestures like flicking ink blots or swishing the "brush" in "water" -- or maybe you can do some fancy things o

It's really interesting to me that most of these are just Bluetooth-connected buttons. There's no pressure or angle sensitivity in the FiftyThree Pencil, it's just a button. I tried to find the "pressure" API in iOS

Interesting that the Surface Pro 2 did so much better in terms of "feel" and "lag". I wonder if the switch to the nTrig panel is behind the regression (I have an old HP TX2 with an nTrig panel; it was always terrible, bu

Yeah, though maybe you could do it with FTIR instead of capacitive, so you wouldn't need external cameras.

I love the work that the Mapbox folks are doing here -- and that they wrote it up so nicely! I have some questions, though! * Why can you only shift glyphs along a straight line during render? Is your geometry somewhat scale-invariant? * Co

sticky isn't expected to change much, and ships prefixed (and with accelerated compositing) in iOS 7.

Many Bluetooth LE devices (including iOS 7) do something similar -- otherwise you'd be able to track people by all of their BT LE devices which are constantly advertising their existence. They cycle their advertised MAC addresses every

I've wanted to write a GLES 2 map renderer for ages -- ever since I saw that the Apple Maps app on iOS uses MSAA for antialiasing (yuck!). It's funny to see all the usual 2D suspects in the source (clipper, GLU tessellator). They

Often school districts have rules on how money can be spent, e.g.: they wont use donations to pay for salaried employees as it creates a liability if they have a shortfall one year and have to pay to lay people off. So that's why a lot

This is awesome! I rewrote EP to use OpenGL (instead of IrisGL) while at SGI, though in retrospect I wish I'd just made it link against Igloo (SGI's IrisGL-on-OpenGL wrapper library). We were moving to supporting commodity graphic
