Ask Slashdot: What To Do When Another Dev Steals Your Work and Adds Their Name?

S3D Open sourcing your private toolset would help (480 comments)

Before signing contract open source your private code library/snippets which you intend to use under BSD license and put into well known repository like Github or sourceforge. BSD license just to calm down your employer/client, that all modifications will remain their sole property, and what they get is some debugged and cleaned code for free, without strings attached. After that whenever question of authorship arise you can point on the traces of BSD code and date of submission into repository, and also demand from employer/client to add BSD copyright note with your name to their code.

Ask Slashdot: Moving From Contract Developers To Hiring One In-House?

S3D Bonuses for no/few bugs looks like a good solution (524 comments)

Pay bonus for product of acceptable quality and make sure contractors confirm online that you are actually paying bonuses. Build yourself a reputation of trustworthy client and you would attract qualified contractors.

Ask Slashdot: How Do You Deal With Programmers Who Have Not Stayed Current?

S3D The same way as with younger programmers (509 comments)

There are always programmers who didn't not bothered to remember their math course. They usually have enough coding knowledge that they provide some value, but from a technical perspective they are a slowly-increasing liability. As an example: I work with a developer who is 10 years younger, but still doesn't understand how to extract rotation matrix from coordinate transformation matrix and cannot be trusted to code gradient descent without causing a mess that somebody else will have to clean up. On top of that, he is really resistant to the idea of refreshing his math skills; I suspect he dislikes people he considers senior to him making suggestions about how to improve his math knowledge. How do you help somebody like this to improve their skill-sets? And, most importantly, how do you do so without stepping on anybody's feelings?

The New AI: Where Neuroscience and Artificial Intelligence Meet

S3D No (209 comments)

Deep learning system are not quite simulations biological of neural nets. The breakthrough in DL happened then researcher stopped trying to emulate neurons and instead applied statistical (energy function) approach to simple refined model. Modern "ANN" used in deep learning in fact are mathematical optimization procedures, gradient decent on some hierarchy of convolutional operators, more in common with numerical analysis then biological networks.

AMD Details Next-Gen Kaveri APU's Shared Memory Architecture

S3D GPU/GPGPU bottleneck (128 comments)

In my experience GPU and especially GPGPU bottleneck is not amount of memory but memory access bandwidth. 256-512 bit is not adequate for existing apps. Before amount of memory will become important manufacturers should move to at least 2048 bit mem bus and also increase amounts of registers per core several times.

Dropcam CEO's Beef With Brogramming and Free Dinners

S3D Re:Hiring assholes is never worth it. (400 comments)

However some projects require for code do something specific, nontrivial and be finished in finite time. Readable, commented, understandable code which do nothing is acceptable for very long projects where managers and team leaders change job before project is cancelled.

Ask Slashdot: Are Timed Coding Tests Valuable?

S3D Funny thing about those tests (776 comments)

I was consulting for division of big corporation and was asked several time to help with interviews. Candidates which did well or at least not bad on my question/tests were invariably rejected by HR of the division. They were too expensive. Workers without experience/knowledge of the field were taken instead because they were cheap. Happily the are not asking me any more.Whole endeavor is depressive.

NVIDIA and AMD Launch New High-End Workstation, Virtualization, and HPC GPUs

S3D There is no "realistic HPC workload" (95 comments)

Specific algorithmic implementation and limitation imposed on it by hardware are wildly different. Some algorithms don't need If's and branch prediction, other do. Different algorithms have different memory access pattern, different complexity of the kernels(for GPGPUU) and different requirement to memory bandwidth. Even on GPGPU algorithms doing the same thing in CUDA and in OpenCL can have several times performance difference. And some algo consist of mostly matrix multiplication, and quite a number of useful methods reach peak GPGPU performance (for example PDE solution). You can't find consistent "average" HPC algorithm.

Windows 8 Graphics: Microsoft Has Hardware-Accelerated Everything

S3D GPU don't do "efficiency" (563 comments)

Why do you think we still use CPU? GPU core can't stop if it started thread, it can only ignore result on early return. Neither it do branch prediction or efficient caching. Basically through into it big data or small data - if the size is not hardcoded it will do the same amount of work. Simplifying it somehow you can say It recalculate whole screen buffer to change a single pixel.

Ask Slashdot: Best Degree For a Late Career Boost?

S3D CS all the way (234 comments)

It give you flexibility. BI at best would give you the same chances as CS for some clients/employers,a nd a lot less for others. MBA could be actually considered detrimental for science/research heavy projects. It could make employer doubt your commitment.

Google Releases Key Part of Street View Pipeline

S3D Re:Mind telling us what are the "Better Technology (44 comments)

Well, I did some 3d reconstruction so I can answer that. The deficiency (not so important for most potential users) is that methods mostly 10-20 years old, no latest methods present. In robust estimators sections ("robust cost function) only "soft" L1 estimator present, no nonsmooth L1 estimators with solvers based on thresholds like Split Bregman and others. No constrained minimizers (solvers) which use Interior Point, Augmented Lagrangian etc. No dense and patch based reconstruction methods support. No global minimization methods(divide and conquer, convexification) I can continue here, but that's not a point. The point is that this package probably for industry users, not for researchers or people who want absolute cutting edge to squeeze maximum out of hardware or have difficult input images. That could be considered to be intentional, because more methods mean more choices, more approaches to test, more parameters to tune.

Book Review: Occupy World Street

S3D I see logicall fallacy here (284 comments)

unending growth is unsustainable and a lie.

because of finite natural resources. Author mix up material output and economical growth. Economical growth don't have necessary be material, and could be increase in consumption of intellectual/informational product, which, at least in theory could be sustained while consumption of natural resources decreasing. Even growth in quality of life don't necessary have to be supported with increase of natural resources exploitation. Technological breakthrough and radical cultural changes can (not necessary of cause, but that is possibility) sustain growth in quality of life with decrease of exploitation of natural resources. Example: such radical increase in quality of life as stop forcing adult females wearing burka does not require increase in material resource consumption. Failure to see such an obvious error make me doubt quality of the rest of the book, though it could be failure of reviewer of cause.

Ask Slashdot: Tips On 2D To Stereo 3D Conversion?

S3D Bundler + PMVS (125 comments)

Download Bundler + PMVS 3D reconstructions packages and feed video into them. Those packages are fairly stable and reliable and they give you 3D point cloud. After that convert 3D point cloud to surface - there are several packages which can do it, but I can't give any advice here - I don't know any *stable* package, all of them are research soft - memory leaks, random crashes, difficult parameters setting, compilation problems etc. If you want to learn algorithms himself that's at least year worth of math and computer vision (if you are not math/phys major). "Multiple View Geometry in Computer Vision" usually recommended for starters, but this book is thoroughly obsolete now. All the modern staff is in the papers.

Symbian OS digital signing mired in problems

S3D S3D writes  |  more than 6 years ago

S3D (745318) writes "Symbian Signed, digital signing for Symbian OS application is causing some discontent among developers lately But now it's not developers, but end-users who are enraged. Latest changes in Symbian Signed forced end-users to go through convoluted on-line signing process for some of popular freeware applications they want to use. As result of end-users flood online signing process slowed to crawl. Helpfully some enterprising Chinese already selling developer certificates to end-users.. And it looks like Symbian Signed had been hacked anyway, at least for some models."

The demise of the Nokia E90 communicator

S3D S3D writes  |  about 7 years ago

S3D (745318) writes "Nokia is not quite famous for the great smartphone design, but in the case of E90 Communicator hardware looks nice. However where Nokia completly failed is software side — the The Register think. The first mistake was replacing business oriented S80 platform with consumer oriented S60. S60 is designed for one-thumb actions — not an adequate choice for full-keyboard communicator. The article go on listing deficiencies and missing features, concluding that Nokia, trying to impress gadget bloggers completely forgot core market of business users. Immature 3rd party application market for Symbian make it unlikely those deficiencies will be fixed."

S3D (745318) writes "After recent verification of the proof of the Poincaré conjecture another Clay Institute's Millenium Problem may have been solved. This one is about existance of the solution of the Navier-Stokes equations under physically reasonable conditions. Navier-Stocks equations describe the motion of fluid substances such as liquids and gases. Penny Smith posted an Arxiv paper Immortal Smooth Solution of the Three Space Dimensional Navier-Stokes System which prove existance of such solutions"
