The complexity (emulation-wise) comes from the fact that it has analog circuitry and has manufacturing imperfections. It's not complex compared to a analog modular synth setup, of course. Emulating it digitally is not just a matter of

There are huge differences in Europe. In Scandinavia you can pay with credit card almost everywhere, starting from a food truck at a festival. They'll have a tablet and a credit card reader connected. Some places don't take cash a

Cryptography can be used to maintain trust, not establish it. If there's no party checking who the driver is (in real life), having a cryptographic certificate isn't much of a guarantee apart from "it's the same guy it w

I see what you're implying but there are lots of places in the world where it's common to hail a ride from a complete stranger and men and women alike do so. There's always a risk of being a victim of a crime when hailing a r

I have to confess that I have pretty much no idea how the filter works or the math behind it. I wrote that part with a friend who has some DSP background but it was essentially copied from a signal processing book :) But it sounds alright a

Just as a point of comparison, here's an FM/AM modulated synth I wrote some years ago [0]. The version linked here is written in 250 lines of plain old C code with floating point arithmetic and not a single thought has given to pe

You're correct. 12 vertices, 20 triangles.

You can almost draw a congiguous hexagon map on a subdivided icosahedron, if you subdivide each triangle edge in 3 parts on each recursive step. Adjacent triangles will form hexagons. This will leave 20 pentagons where the vertices of the

Yes, a failure at safely distributing software is a pretty big failure when it comes to distributions. Mint, elementary and the other "user friendly" distros should focus on creating the desktop and leave the distribution part to

It's impossible to tell the level of autonomy from this article. What was shown in this article could qualify as Level 2, 3, 4 or 5. To provide proof of Level 4 autonomy with video (in certain conditions), it would need to show adverse

Yes, I absolutely do think that some kind of car-to-car communication is required for these situations. It's not an impossible problem to solve, but I have not heard of any efforts to create a car-to-car or car-to-road communications p

"Level 4" means that no human intervention is required and in case of conditions going from good to bad, the car can autonomously put itself in a safe state. That was nice and clean city driving in the video clips but nothing that

Price won't be an issue unless there will be content worth that £350 coming out in the next 5 years. If the VR hype fizzles down in the next year or so, it won't happen. Don't get me wrong, I've tried most of the VR gadg

Reason 3: some of the ads are a downright scam. Seriously, using some free apps makes me feel like it's 1998 again with the "you are visitor number 1,000,000" and "your phone might have a virus - click here for free remo

That gets linked every now and then and it's pretty much BS, coming from someone who was an intern for a few months. Yes, there are workarounds and tweaks in the driver but it there was no other way back when games were shipped on a CD

I would cautiously agree. The overall quality of VR - the headsets, the displays, the content - is just not good enough on current-gen devices (especially considering the price). Unlike 3D TVs, VR might be here to stay for the enthusiast ma

Yes! A bit of common sense would be useful here. The current generation of self-driving cars is fairly impressive already, but what I'd like to see is a city full of them. I have a feeling that self-driving only works as long as the ma

The key distinction here is that a Level 4 is safe even when the driver does not intervene . If it starts snowing, the car will park by the side of the road if the driver isn't there to pick up the wheel. Level 3 is when you have ampl

The naming is odd, because the syntax hasn't changed, only the semantics of some operators have changed. An example of syntactic sugar is list comprehensions. It's a new syntax for expressions using map, filter, etc. It's &qu

I dropped a comment on his blog and a link to this discussion... And how sloppy of me! I didn't notice the `pre;` in the code consuming most of the time (to be fair it's just 4 characters and I didn't put too much time to it)

I am surprised to see any speedup in this! I'd expect something trivial like this to be completely memory bound with the CPU sitting almost idle waiting for bytes coming in from memory. Looking at the benchmark code, this is using rdts

Can you come up with a vectorization optimizer pass that could do what the OP did in the article? This isn't a compiler bug or a shortcoming, it's a non-trivial optimization. Especially given the aliasing between the input and out

I've seen this elsewhere too. For relatively mundane task (I think it was Morton code conversion), a giant lookup table was constructed and it gave a nice 2x or 4x performance improvement. But no application will ever be doing only str

These are all great options for massive parallelism, but that's not what I'm after. I want explicit SIMD with 2/4/8/16 wide vectors, primarily to be used with 3d graphics and physics calculations.
