2 + 2 = 4, er, 4.1, no, 4.3... Nvidia's Titan V GPUs spit out 'wrong answers' in scientific simulations

Spacedman

Re: Are they using the wrong datatype?

Not necessarily. Floating point arithmetic is not commutative - (a+b)+c =/= a+(b+c) [https://en.wikipedia.org/wiki/Associative_property]. If you are running on a parallel system you can't be certain which order operations will be done in - it will depend on how the system has scheduled your calculation out to the processing units. I've had this happen when running statistical models using OpenMP on a single CPU, on a GPU it wouldn't surprise me at all.

Critical VMware bug needs patching ASAP

Spacedman

Re: keep it

I go through hell whenever I need to access VMs to install. Its not something I do often, so every time there's a new barrier. First there's the issue of getting the latest version of Flash working with Linux and whatever browser I find most stable at the time. Then there's the Client Integration Plugin to deal with. Which doesn't exist for Linux with vSphere 6.0 now. So I logged in remotely to a Windows box, tried the native client there, it didn't do things the Web client could do, so I was flipping between them, and after a day I did eventually have a new VM sitting there waiting to be virtually booted.

At which point I noticed it didn't have a network interface. I couldn't add a network interface. At this point I sent an email to the cluster admins (because it smelt like a "we havent given you permission to create networks, but we're not going to give you an error message that explicit" situation) and I've heard nothing since.

How one developer just broke Node, Babel and thousands of projects in 11 lines of JavaScript

Spacedman

Re: Bloody stupid!

Unless you're a real idiot developer and deserve to have a broken site you *wont* be loading your JS from lots of random sites. You'll use bower to download the dependencies into your project where they will live quite happily. You then push your site to the server. And the site will work even if the original dependency developer throws their toys out from the package archive.

What will then break is the build process. The site wont. Nobody has <script src="http://npm.org/left-pad.js"> in their site - alongside the other 2000 script tags you need it would take forever to load.

Spacedman

Re: This whole debacle mirrors Gamergate

Well not really much. Developers will get the dependencies as they work (using bower or whatever the JS dep manager tool of the week is), and then build a single JS file at deployment time (using webblywobblify or the JS build tool of the week), and that goes up to the server for production. I doubt anyone has every done <script src="http://randomsite.com/pad-left.js">

I'd only ever load something from a non-local site if it was something I regard as stable, popular, and coming from a robust CDN.

Re: but Python is creeping up there

Maybe now, back in t'day it (well, "S") was for people whose tool set was FORTRAN. An interactive data analysis n stats platform with graphics? Flip yeah. No more compiling, linking, running, dumping output to some format UNIGRAPH could understand for plotting...

Python is really getting there for data analysis with numpy and pandas, still lags R on graphics though. However I reckon the machine learning people - and lets face it, that's what Teh Big Bznesses want to use their analytical engines for - are 50/50 Python/R.

Well, if you want to call John Chambers a "new-to-programming stats geek" then yes:

Mozilla to boot all plugins from Firefox … except Flash

Re: So no AdBlock, NoScript, or RequestPolicy then

Just stick "about:plugins" in the URL to see what plugins you have installed with version numbers and paths and all that icky technical stuff they don't want you to know.

Go to "about:addons" and get a more fruity page where you can also list "Extensions" (which aren't going away) as well as the "Plugins".

My big gripe is the VMWare web interface plugins - they are NPAPI and so don't work on Chrome, and VMware show no sign of porting them. My current solution for VMware host management on Linux is Firefox with Pepper Flash via FreshPlayer (so I get a high enough version number of Flash) and the VMware plugins via NPAPI. Fragile as heck.

Re: Why?

I think the only reason news sites like to have an app version is because they are still surfing on the "There's an app for that" buzz from the old iPhone launch however many years ago, and there's an expectation of appyness, and branding, and Siobhan from Perfect Curve suggested it.

But mostly...

Because....

Re: Another Open Source security problem

plugin hell

Getting the current VSphere web client working on a Linux desktop was fun. Firefox doesn't support a high enough flash version, and Chrome doesn't support NPAPI plugins anymore which you need to mount local ISOs. Eventually found a shim for FF that lets it load Chrome's PPAPI-interfaced Flash. But I get the feeling its very fragile. Anything fixed in that regard?

Maybe I should ask our IT managers for a Windows VM just for running the native client...
