Submission + - Linux Kernel running in JavaScript emulator with graphics and network support

warmflatsprite writes: It seems that there have been a rash of JavaScript virtual machines running Linux lately (or maybe I just travel in really weird circles). However until now none of them had network support, so they weren't too terribly useful. Sebastian Macke's jor1k project uses asm.js to produce a very fast emulation of the OpenCores OpenRISC processor (or1k) along with a HTML5 canvas framebuffer for graphics support. Recently Ben Burns contributed an emulated OpenCores ethmac ethernet adaptor to the project. This sends ethernet frames to a gateway server via websocket where they are switched and/or piped into TAP virtual ethernet adapter. With this you can build whatever kind of network appliance you'd like for the myriad of fast, sandboxed VMs running in your users' browsers. For the live demo all VMs connect to a single private LAN (subnet 10.5.0.0/16). The websocket gateway also NATs traffic from that LAN out to the open Internet.

Submission + - AMD Confirms Kaveri APU is A 512 GPU Core Integrated Processor (hothardware.com)

MojoKid writes: At APU13 today, AMD announced a full suite of new products and development tools as part of its push to improve HSA development. One of the most significant announcements to come out the sessions today-- albeit in a tacit, indirect fashion, is that Kaveri is going to pack a full 512 GPU cores. There's not much new to see on the CPU side of things — like Richland/Trinity, Steamroller is a pair of CPU modules with two cores per module. AMD also isn't talking about clock speeds yet, but the estimated 862 GFLOPS that the company is claiming for Kaveri points to GPU clock speeds between 700 — 800MHz. With 512 cores, Kaveri picks up a 33% boost over its predecessors, but memory bandwidth will be essential for the GPU to reach peak performance. For performance, AMD showed Kaveri up against the Intel 4770K running a low-end GeForce GT 630. In the intro scene to BF4's single-player campaign (1920x1080, Medium Details), the AMD Kaveri system (with no discrete GPU) consistently pushed frame rates in the 28-40 FPS range. The Intel system, in contrast, couldn't manage 15 FPS. Performance on that system was solidly in the 12-14 FPS range — meaning AMD is pulling 2x the frame rate, if not more.

Sorry, the above information is incorrect. I just found out (after same googling) that it is possible to install the 8.1 update without a registration if you switch the user account to "local user".
Although it would be better to just get a downloadable service pack without the market to put it on a usb stick...

Last week I installed win 7 sp1. All updates were under 1gb to download.
Today I got a new Notebook with win 8 from a friend to make it usable. After the first update (620 to 650mb (wtf? they can't tell you how big the updates are)) and an hour, hitting the button a second time it wants to download 1042mb (this time precise).
And this is without the 8.1 update. For now.
For me this makes win 8 look like a complete, rushed mess!

Not complety free... You have to register, give away your soul and download 2.5GB from the market (unless you have a technet subscription or whatnot).
Why can't I get this with normal windows update? Just to force people to the shit-full-screen market?? I do have to download it everytime, can't put it on a usb stick...
It's a punch into customers faces (imho).

This reminds me of the sm(s) business model: You already could send emails a few mb large (for almost free of charge) in pc world, then someone came and thought Yeah, i would like to make same kind of this service with mobile phones as well. In the beginning sms were quite expensive, for just 160 (i think) letters!
But, to my surprise, it worked out...
