Was dissatisfied with existing crossword assistance sites, as they all seem to have 2010-era UIs and be so ad-heavy as to be almost unusable. This is my attempt at a fast, light crossword assistant that works well on mobile.

Author here. I did consider this, as others have reported getting ADS1015 marked as ADS1115. If it were an ADS1015 the readout would be truncated at 12 bits. These parts definitely delivered 16 bits of readout.

As I read that summary, feature sizes start at 22.5 µm and go down to 75 nm.

As they say, "significantly lower than the wavelength of visible light".

(author here) Fixed, thanks!

This happened to Lance Armstrong. As one investigator put it, his 1999 urine was meant to pass the drugs tests available in 1999. But when subjected to tests developed 5 years later, it failed.

Using premultiplied alpha avoids this. Jim Blinn's books from the 90s give a very thoughtful treatment of the topic.

It's hard. Because everyone claims to be doing TDD, just asking in the interview "do you do TDD" is pointless.

Example. Last year I consulted at an IC company, building a huge "moon-shot" chip. You might expect TDD to be an absolute certainty in such an operation. Not so, individuals had all sorts of justifications for not doing TDD.

Here is one idea. In the technical interviews, when the inevitable "and do you have any questions for me?" moment comes up, ask them to talk about their best test.

If they have a good answer, it's likely you've found somewhere that genuinely values TDD.

Yes, ICs age. Fissures in the subtrate expand with each thermal cycle. Delamination is a similar effect. That's how manufacturers prematurely age their parts -- by endless cycles in the oven.

The biggest culprit is flash memory. It's in almost everything, and has a much shorter life than the 10 years most manufacturers claim.

Spirograph is an excellent way to introduce kids to the idea of relatively prime pairs.

Because the most awesome Spirograph patterns come from the relatively prime pairs of gears.

The debiasing idea is due to von Neumann himself:

Yes, that is the Guardian's current project.

I have an asynchronous CPU cluster on my desk right now (a pair of GA144s). The performance spread isn't actually very dramatic; just a few percent. After all, the foundries aim for consistency so that synchronous devices get good yields.

Regardless of the Nyuzi's merits, that demo is unimpressive.

We (RenderMorphics and then Microsoft D3D) were happily spinning teapots on 50 MHz 486s, significantly faster than that.

Yes, upon being insulted the best response is to avoid being insulted. The idea goes back a long way.

Yes, the PDP-11 instruction set makes null-terminated strings especially efficient. Strcpy() is 3 instructions per character, for example.

The PDP-11 features that make this possible are (1) post increment addressing and (2) MOVE instructions set the condition codes.

I make chips for a living, and if I had screwed up this badly I would fully expect to be fired. Being fired for incompetence is much more demeaning than gentle mockery by people writing a workaround.

Since everything is always getting worse, at some point in the future we will look back at the clickbait nonsense of 2015 with genuine nostalgia.

"Those were the days of real content. Before it all turned to crap"

Shudder.

Instead of that complicated minute/day/week/year data retention scheme, why not just randomly replace an entry in a fixed-size store? So the probability of a datum being in the store is inversely proportional to the log of its age. And it's a one-liner.

I write Forth code for tiny microcontrollers that are embedded in ASICs. They are ROM-based, and have to work first time. Size is a few hundred bytes, so C is out of question.

For a first hand account of the telegraph revolution, I enjoyed reading this state-of-the-art report from 1860:

FWIW I have a 16-bit version of the J1 CPU running on this FPGA; it uses about 75% of the available gates.

I have something along those lines in progress now... if you mail me at the address on this page:

I will let you know when it launches.

David E.H. Jones pointed out that the socially sanctioned drugs have something in common: they all taste bad. Or at least, they have a taste that is unappealing to children, and then must be acquired by special effort. Coffee, tea, tobacco, alcohol: all taste pretty awful to a ten-year-old.

"Isomorphic". I do not think it means what Yahoo thinks it means.

As the person who wrote the OpenCV Python bindings, this makes me inordinately happy.

Gameduino does have an on board coprocessor for that kind of in-the-video-loop work. Sample "beam chaser" that does a split-screen scroll:

Implementing a complete application using an FPGA was actually surprisingly pain-free. After a while the fact that the code gets compiled into hardware stopped seeming like a big difference; I just started thinking of the FPGA as a parallel computer. Anyway, I will attempt to answer any questions from HN here. Thanks for looking.

Yes, step by step. I find post its with the new commands work great.
