A large publicly available depth image dataset could be quite valuable as a research tool.

I think the problem you'll face is that there are lots of ambiguous inputs: the same pixels could be an image of something small close up or something large further off, for example. That's likely to confound the training process. The kinec

That has been borne out by my experience so far too. There have been several successful efforts at writing better performing general-purpose allocators: * TCMalloc (http://goog-perftools.sourceforge.net/doc/tcmalloc.html) * jemall

A bit off-topic, but I'm curious: why do you think that's impressive? I thought it was pretty commonly accepted these days that readable code saves more time than it costs over the life of a project...?

I don't claim to have any special knowledge here so yeah, could be. I didn't know about that flag BTW - thanks for mentioning it. It sounds similar to O_DIRECT on linux?

It's not rare at all. A double takes up twice as much memory as a float and memory bandwidth is a precious commodity these days. If you have a lot of numbers (e.g. in 3D models or similar) and don't need the extra precision, using floats is

The disk performance problem may be because all the file accesses effectively flush the disk cache, rather than just the number of seeks. Other than that, couldn't agree with you more (and that's why I don't use Windows machines these days

I was really just trying to make the point that there is more than one kind of return on an investment. Money isn't the only motivating factor.

I guess it depends how you measure ROI? People usually do PhDs in an area that interests them; if they then go on to an academic or research position, it's possible for them to spend their entire career pursuing their own interests. That so

What's your reasoning? FWIW I always thought Fedora was aimed at more tech-savvy users, not "ordinary" users (whatever that may mean).

Either that or the consumer-grade digital cameras will start to evolve in new directions. I think we're already seeing the beginnings of this with Lytro's light-field camera, for example. I wouldn't be surprised if we start seeing light-fie

Good work, like it a lot! I've really missed having an easy-to-use queue in iTunes, it's great to see it put front and center. A bit of (hopefully) constructive criticism: I don't think you should add a whole album to the queue when I doubl

Lex and Flex both generate C (Flex has an option to output C++ instead, IIRC), yes. There are similar tools for other languages though: Java has JLex, ANTLR, etc. for example. Re: the config file - how often does it change? Does it really n

There's an assumption that compiling to Java source will make this easy for Java developers to transition to, which I believe is completely misguided. If you edit the generated java source you give up the ability to use Xtend at that point;

It matters more when you've got a statement broken over multiple lines. If you've got a function which takes a lot of arguments for example, lining them all up vertically can make the code a lot easier to read. This can be difficult or impo

I'm not sure where the article got that 50 Mb/sec figure from, but it sounds a bit low. Uncompressed, it's more like 50 Mb per frame - 1.5 Gb/sec (4096x2160, 3 channels, each channel is 16 bits, up to 30 frames/sec). According to their te

The way I see it, they're linked. The memory hierarchy has a direct impact on a number of architectural concerns: data organisation, choice of components, communication patterns between components, etc. It can make the difference between a

About the performance issues? Well I work on software that does image processing at the moment & we've chosen to represent images as separate channels (i.e, all the red values, then all the green values, then all the blue values, etc).

It's clear from Fowler's discussion of "mechanical sympathy" that he didn't understand the memory hierarchy. I found it pretty shocking that someone in his position could not know this stuff. He really needs to read Ulrich Drepper's "What e

Where do you get that from? The only reference to the GPL that I noticed was in section 2.2, which expressly forbids you from doing anything which could make the code become subject to the GPL.

The subject is a bit misleading: this is a new computer vision library. There is a separate augmented reality library which lives on the same website, but the two don't appear to be connected. FastCV has the potential to be interesting, but

Qualcomm's augmented reality project, from the same site, has license information available here: https://ar.qualcomm.at/legal/license/ I'd guess FastCV will have a similar license.

I think this might be a better metric for stability or reliability of the distros, rather than their health: I suspect many people only sign up to these forums when they want to ask for help with a problem. Anecdotally, over many years as a

The grant might have been instrumental in getting them to bring the project to Sweden rather than any of the other Arctic circle countries though.
