Rmagic and octave magic work pretty well in my experience (which rely on Rpy2 and oct2py)


Bootvis used to be the go-to tool before Microsoft discontinued it. Good to see there's an alternative now for win 7 & 8, but why on earth does it need to be bundled into a 5 gig download?


If you choose the advanced installation option in Windows ADK, you can choose only to install the Windows Performance Toolkit which is under 80mb.


It really hinges on whether the game is a discrete artwork, kind of like a book or a movie, noone wants to have to pay to see the ending(pay $10 to defeat the boss), or whether it is a developing story and the Pay to play choices are analogous to something which makes sense, i.e. pay your taxes or else you become an enemy of Captain Hector.


How prevalent are bootkit (MBR) malicious exploits though? Surely the right place for this is for windows to prevent boot modification without authentication though UAC or something similar?


It already exists. http://www.stoned-vienna.com/ I also read that it was trivial to make a "boot kit" for Windows 8 without secure boot. I actually think it a very big deal and hope many Linux distro's develop something similar.


Secure boot is a form of defense in depth that is really only needed if the kernel is compromised. So yes, the attacks that it prevents are hypothetical and may never exist. And yes, it may be too high a price to pay for the unknown level of protection that it provides.


A compromised kernel does not seem that unlikely. I am not fammilar with Windows, but I assume it supports hotloading code into kernel space (like modules in linux), given this, it would be trivial to get from root in userspace to arbitrary code execution in kernel space.


Between driver signing and kernel patch protection, it's harder than you think. But clearly Microsoft is preparing for that sort of compromise.


If some signed driver is found to have an exploit, is there a mechanism to revoke the signature?


How does the actel toolkit compare with the xilinx toolkit?


My attempt using matlab(octave) to generate a 100x100 version of the image (using his function description):

https://gist.github.com/3903785

Hadn't figured out if there is a way of vectorising it further. Would appreciate any tips if anyone has any.


I've managed to hack it into a semi-vectorised implementation which works up to 700x700 before it runs out of memory.

Interesting! You dont have the squares. This is a hint that the squares in my version are due to floating point limitations.


It's probably a combination of floating point errors adding up.


Giving the guy a break, it does look like he doesn't "get" github, as it hosts the sources(not in an easily buildable format) as a binary download. and the content of the repo is just random batch files.

And, regarding batch files, if it gets the job done (i.e. M4 autoconf scripts). What would powershell give you?


Essentially, excel is a functional language, without the ability for recursion. If there were a built in array datatype, that'd be possible. There's a few papers floating around explaining an integration between Haskell and excel, described in some places as hsExcel, but I haven't seen a working copy.


Or there's always the lighter weight option pyspread[1] in which cells are objects, works with numpy arrays and any module.

Last I looked, the vector math part of 3D wasn't handled by webGL, this uses Three.js to handle that, and looks to be the main bottleneck. Until you can do matrix/vector math using hardware, webGL is pretty much useless.

Modern matrix libraries like glMatrix

https://github.com/toji/gl-matrix

use typed arrays effectively to do very fast matrix and vector math in JS. A modern JS engine can transform such code into something very efficient, more than fast enough to do things like even first person shooters.


That is pretty much about right. I wrote a bit about the implementation[1], and the discussion went over how to optimize this (including, but not limited to, using shaders to do the drawing and not relying on Three.js so much).

Would be interested if its worthwhile/possible using shaders as a wrapper for three.js. All I got when I was searching was there was a mozilla bug report and a hacked patch to expose SIMD through js[1], and a project to add SIMD support to vectors in Dart[2].
