That would be nice, but I think the issue is less one of documentation (lots of demosceners into reverse engineering) but that there are (a) just too many different graphics cards out there (b) the platform lifetime is very short (c) less m

But the stereotypes of technologically illiterate "designers" and neckbeard, tasteless "developers" are outdated, though unfortunately still pervasive in the industry The problem is that one person cannot possibly learn about everything.

These recaptcha CAPTCHAs are becoming ever worse. I've seen many people struggle with them and even ask my help to decode them (because, hey, a computer person probably knows how to decode the code). That can't be the purpose? If you're usi

That's indeed a bad idea. etckeeper creates a local repository in a protected .git directory inside /etc, don't confuse git with github or other hosting services. I use etckeeper on various machines, just to track changes in configuration

Indeed interesting how different educations differ. We certainly learned some of that, but it was never the center of attention. Geometric algorithms were another larger focus. Ofc there is so much to learn and it's only possible to confer

Computer science is a very wide field these days. I am a computer scientist but my education (math-wise) mostly focused on numerical math, not high-level symbolic logic. Sure, I could understand it if I took the time, but it certainly looks

Very nice! Feels very atmospheric and relaxing. It makes me think of a bit of a Matrioshka Brain structure (for example from the Alistair Reynolds story Troika), with a star and surrounding shells that capture ever more of the light. Techni

I don't expect this to happen, ASICs will be pretty widely distributed before anyone can pull this off. However there is a contingency plan for when this happens: switch the hashing algorithm (for example to scrypt, or something memory hard

It supports floating point. Just not double precision floating point. That's good enough for 3D rendering.

This is wrong. For example, low-power embedded ARM chips are not simply cut-down high-end x86 chips. If you optimize for power usage instead of raw performance, there are many design decisions that come out differently, resulting in a desig

Interesting architecture. I like how well-documented everything is. Usually, either the low-level ISA for accelerator chips is not documented at all (like with GPUs), or detailed documentation is only available under NDA, and only proprieta

Fair enough. I agree it can be funny, just somewhat immature. The line between bullying and "self referential in-group humor" is pretty thin sometimes. I guess it's a bit like sexist jokes, in that some things that are meant as funny can be

Yes. You'd expect a community such as hacker news to be above the usual nerd-shaming.

Cool. This is actually a good use of bitcoin. And I like how it directly links to github.

On the other hand, writing about your work may actually help you take it further, as it forces you to organize things in your head (a bit like rubber duck problem solving). That's my experience, at least.

That depends on the kind of change. There is actually a list of changes that are of high impact to the network and block chain but may be implemented nevertheless https://en.bitcoin.it/wiki/Hardfork_Wishlist Of course, none of these are m

Me too. It's one of the only ways of keeping people that make long-term predictions accountable. Usually, no one calls them out if they were wrong, they only get the attention and praise if they were right.

The fact that it is trivial to maliciously craft the length field makes it cheap for the attacker to try to exhaust receiver memory, overflow buffers or make DDoS attack more effective. If you use a delimiter, the attacker has to at least

I'm probably the least fan of Microsoft in the world, but I have to agree with you on that. More generally, cloud products are extremely convenient on the surface, but beneath the water there is an iceberg of trouble. Especially when you do

It is already possible to select mBTC (1/1,000) and μBTC (1/1,000,000) units in the client. That should be sufficient, at least for now. For nBTC (1/1,000,000,000) the 8 digits in the protocol are no longer enough, thus some more work will

He was spot-on with some of the issues (too bad he acted so tragically...). Writer Derrick Jensen makes this point as well. The problem is that none of these anti-technologists really come up with a solution, except maybe to live in a hut i

What is the problem with being connected? I think it is good to strive for connectivity as it encourages cooperation. Of course you need to be careful with what you trust and what you don't trust, and spread the risk when a connection goes

I'm fully aware of what is happening, and how things appear to be going the "wrong" direction, at least according to the tech news. Don't let that despair you. What I proposed was something we (as in people with intimate knowledge about t

I understand your feeling, I know it very well. But that isn't a choice. There is no way to "stop technology". Humanity has always been about technology, from the moment we started picking up sticks. All we can really do is make sure that t

Two promising open source cryptocurrencies that are not bitcoin forks are Ripple and Opentransactions. These can also be used on top of Bitcoin, or the others, to provide some functionality (such as decentralized exchanges) that Bitcoin its

I don't know how up-to-date it is, but there's this list of libraries and packages: https://bitbucket.org/pypy/compatibility/wiki/Home I'm mostly missing Qt GUI support myself. Hopefully cppyy ( http://doc.pypy.org/en/latest/cppyy.html )

Sounds like an interesting initiative (if serious), but I can confirm this has nothing to do with the Bitcoin project or foundation. They may use bitcoin, but that's all.

Isn't that what "ssh-keygen -R" command is for? Though I agree that your solution is more generic.

Yes, grate is similar to my effort for Vivante GPUs https://github.com/laanwj/etna_viv . I'm not sure how they confused this with official NVidia drivers, as it's built by a third party. NVidia open sourcing drivers would be huge news ind

One reason I can think of would be because it's "not done" in international diplomacy to publicly admit of hacking. I don't think any country ever openly admitted to building Stuxnet and other "cyberwar" botnets either. Or maybe they did ev
