Detector vans are mostly a hoax. It's thought that they worked by detecting electromagnetic radiation given off by CRTs, if they worked at all. Those are obsolete, so the point is moot anyway. But how should they be able to tell apart

That's not the point. 80 dB isn't twice as loud as 40 dB, either, it's much more than that.

by lorenzhs 10y ago
Your noise scale is off. 60dB is restaurant conversation level noise. For comparison, Notebookcheck's system noise scale is 30dB=silent, 40dB=audible, 50dB=loud.

Others have speculated that the tunnelling may be in preparation for a Mars colony, where underground living spaces have the advantage that they're protected from radiation.

Well I think it's a mixture of both, "disproportionate coverage" is a fair description, insofar as it misrepresents the activities and opinions of the research community (most of which appears to consider it hokum). I'll

They've been criticised for twisting physics to support the conclusions they want to draw from it, even if there is an alternative and much simpler interpretation of the results, see http://www.math.columbia.edu/~woit&#

It is for compiler authors, or libc etc. There's very little most application authors would need to do.

Yes pi3g is terrible. Kiwi Electronics (Netherlands) seems very reasonable (€15.50 to Germany), along with The Pi Hut (UK, ca €16).

I found at least one UK seller that will ship to the EU for £4 (€4.70) and the US for £5 ($6.20), and they seem to have some in stock still. Just shop around a bit.

As I mentioned in another comment, you can get one for $18 shipped from a UK seller (The Pi Hut): https://news.ycombinator.com/item?id=13753174 Max order quantity is 1, though.

Yes, it's £9.60 for the RPi Zero W and £2.50 for shipping. You can buy it for £12.10 ($15) total in the UK. Not too bad, eh? Shipping to Germany from the same UK seller would be £4, or £5 for the US. That's a total of £13.60 &#x2F

Note that NASA encourages its contractors to use their stuff for private missions as well—building more of the things reduces unit price (by amortising development cost) and thus costs for NASA, so it could be that this results in lower ove

I hate subtitles that aren't in the same language as the audio, that's just incredibly confusing. Having both in the foreign language requires a higher level of proficiency, sure, but I find it a lot more rewarding.

I'm well aware how to analyze a dynamically growing array (each insert "pays" for two moves in the future), but I'm not sure what you're getting at. The amortized complexity of appending an element to the end is θ

by lorenzhs 10y ago
> why adding to the end of an array that doubles when it expands is O(n) amortized Not to be overly nit-picky here, and technically O(n) is correct as well (it's also the un-amortized worst case of insertion), but you probably mea

I use WeeChat ( https://weechat.org/ , running on my server) and Glowing Bear ( https://github.com/glowing-bear/glowing-bear ) to connect to it from wherever I am (desktop or mobile), it works very nicely.

If you use this, you can also generate TOTP codes on your computer using the yubioath Desktop application. It's quite neat.

Apple has already done away with the headphone jack, and re-enabling use of the headphones would probably mean having to add a receiver to the tiny circuitry in the plug that houses the DAC. That sounds like a lot of work for a niche featur

Yes, generics in Java or templates in C++ is how any algorithms library would handle this. Any type passed into such a function needs to possess the required operators and functions or it will fail to compile/run.

The two are not mutually exclusive, and the set of people who could work on either of these is probably mostly disjoint. "Don't fix problem X because problem Y is more important" isn't a helpful stance if we can work on

I guess it comes down to familiarity and experience with the language and tooling, as well as predictability of performance. Achieving C++-like performance in Haskell seems possible from all I've seen, but also requires a lot of experi

There are U2F alternatives, several of which are mentioned in this thread. Also, U2F is immune to phishing while TOTP isn't. Your advice is actively harmful.
