Comment Re:NEMA 4X is all you need? (Score 2) 202

Thanks for the very informative answer and suggestions. In response to one of your questions about why I think I need such a high end graphics card, I need to do "real time" (ideally at 30fps) processing of 3D data. My current prototype (which isn't ingress protected in any way) runs at around 10-15fps, and with the GTX970, performance bottlenecks are no longer on the image processing side of things (uploading the images to the GPU now takes more time than the calculations), which they were using an older GTX650ti. Unfortunately, moving the data elsewhere for processing isn't an option - there is no guarantee of decent connectivity and the amount of data will be at least 25GB a day. It doesn't need to have a permanent display though, which makes life somewhat easier!

I can certainly make the box larger as you, and other slashdotters, suggest. In fact I've not "been" painted into a corner, I've painted myself into a corner and am always very happy to look for alternatives as you suggest. I'm a big fan of the keep-it-simple mentality! Ideally, an off the shelf solution would be perfect, but having talked to a few of the embedded pc manufacturers as well as endless googling, it seems that I'm going to have to design/build the solution myself. I very much appreciate your answer and clearly you have a thorough understanding of the types of issues I'm facing, and in a way I'm glad that I haven't missed something blindingly obvious!

I'm also realistic in that I don't expect the first prototype to work without hiccups, but if I can incorporate as many of the suggestions as possible in the design, then I can hopefully keep the failure/damage/rebuild rate as low as possible.

Thanks again for your post.

Submission + - Ask Slashdot: How do I make a high spec PC waterproof?

jimwormold writes: I need to build a system for outdoor use, and capable of withstanding a high pressure water jet! Embedded PC I hear you cry. Well, ideally yes, however the system does a fair bit of number crunching on a GPU (GTX970) and there don't appear to be any such embedded systems available. The perfect solution will be as small as possible (ideally about 1.5x the size of a motherboard and the height will be limited to accommodate the graphics card). I'm UK based, so the ambient temperature will range from -5C to 30C, so I presume some sort of active temperature control would be useful.

I found this helpful discussion http://hardware-beta.slashdot...., but it's 14 years old. Hence I thought I'd post my question here.

Do any of you enlightened slashdotters have any insights to this or know of any products that will help me achieve my goals?

"instead its more a backup tool - just like Spideroak."

Well spideroak allows syncing of different folders on different machines, so in that respect it's more like dropbox on steroids than mozy.

Additionally Spideroak has standard backup features that numerous providers give (including mozy) but gives you up to 50GB storage free.

Comment Spideroak? (Score 2) 188

Why not use Spideroak instead of dropbox. Spideroak have a zero-knowledge privacy policy. I'd say it's not quite as polished a product as dropbox, but everything is encrypted before it leaves my computer (come on spideroak open source your client so we can check!) and stored encrypted, so NO ONE can read it. I have access to files from android to. (I am not affiliated with Spideroak in away way.) Join via this link and we both get an extra 1GB (I believe you start with 2GB free): https://spideroak.com/signup/referral/dd998cb68d2fba5eb916a000411c2263/

Submission + - Company stores password in plaintext - help!

jimwormold writes: We have seen the dangers of storing the passwords of online user accounts in plaintext on databases (Sony, I'm looking at you).

I have recently discovered that an ISP here in the UK does the same. I have pointed out the inherent riskiness of plaintext passwords to their Technical Support team, but they don't seem to appreciate it.

Yes, I could just up and leave, but that doesn't help all of their other customers.

What would the erudite slashdot reader suggest it the best approach here to get the company to adopt a secure policy?

Let's hope they don't think that as it would be incorrect.

They are not receiving public money, they are (were) just not being taxed on all their earnings. There's a difference here which you may have missed.


Submission + - Found lung cancer genes, blood test may be next (alphagalileo.org)

Stoobalou writes: Norwegian researchers have discovered genes that increase not only one’s risk of lung cancer, but perhaps one’s urge to smoke as well. Now these researchers are working on developing a blood test for lung cancer.

“Smoking is by far the largest risk factor for developing lung cancer,” says Professor Frank Skorpen of the Department of Laboratory Medicine, Children’s and Women’s Health at the Norwegian University of Science and Technology (NTNU) in Trondheim. Professor Skorpen is among the researchers in a project studying genetic factors and treatments for lung cancer. The project receives funding under the National Programme for Research in Functional Genomics in Norway (FUGE), one of the Research Council’s seven Large-scale Programmes. Genetic factor doubles the risk.

Submission + - Doom creator: Direct3D is now better than OpenGL (bit-tech.net)

arcticstoat writes: First person shooter godfather and OpenGL stickler John Carmack has revealed that he now prefers DirectX to OpenGL, saying that 'inertia' is the main reason why id Software has stuck by the cross-platform 3D graphics API for years. In a recent interview, the co-founder of id Software said "I actually think that Direct3D is a rather better API today." He also added that "Microsoft had the courage to continue making significant incompatible changes to improve the API, while OpenGL has been held back by compatibility concerns. Direct3D handles multi-threading better, and newer versions manage state better."
