Sales tax has nothing to do with the cash payment. The sensible thing to do is to round towards nearest divisible-by-5-cent number. That's what other countries do.
So if you buy an apple and with sales tax it's $1.02 you pay $1.00 in cash. If it's $1.08 then you'll pay $1.10 in cash.
Or you can pay exact value with debit/credit card.

I do building automation stuff. A customer wanted an Echo in each room. I tried integrating it to our system using the home automation skill set. It worked 80% lights on, lights off, turn thermostat up: OK. Turn thermostat down: "I've added chopped potatoes to your shopping list". I also had trouble getting it to trigger on the word "alexa" (I don't have a strong accent). This was for a hotel with international customers. That made me realize that Alexa was not ready for use in hotel rooms.

The video titles are sometimes translated if the creator has dumped translated titles (and sometimes subtitles). And there is NO option to deselect that because Youtube knows best. The problem is that the translations are sometimes hilariously wrong or misleading.
For one Italian/Tuscan cooking channel I want the original audio and then whatever subtitles they have. If Youtube doesn't make the dubbing feature user-selectable I have no way to verify what is actually being said, and I'll end up with weird stuff such as adding a small goat (caprino) and a rocket (ruccula) to the plate,

Youtube creators cannot be trusted to provide translations or dubbing, because they trust auto-translation or too-cheap translations agencies.

We (Findx) didn't remove search terms. We did add synonyms and word variations (with lower score of course).

We shut down in 2018. I would say that our downfall was that the team was too small (there's a lot of work in making a search engine), and that we didn't have a large enough user base to use user clicks to rank results

Comment Re:Oh lawd, not the formal methods bullshit again (Score 1) 239

I took a course that involved formal proofs of correctness. I've never proved any of my programs correct, but the course changed the way I think about programs. For subroutines and leaf functions I keep in mind pre- and post conditions, loop invariants, object invariants, etc. Sometimes I even write the pre and post conditions as comments. That had reduced the number of bugs in those areas and helps focusing on the higher-level problems.

My pet peeve with auto-translations is that they often misses the context, so homonyms get translated incorrectly. But something worse is what google-translate is obviously doing: when translating from language X to language Y and it doesn't have a direct translation for a word it goes via English hoping for the best. Where I encounter that most of the time is when youtube translates Italian cooking shows to English/Danish/German and the results can be hilarious. Eg:
  - Caprino, literally "small goat" but in this context it's a type of goat cheese. Translation "Now add goat to the pasta..:"
  - Or: "rucula" where it sometimes misses the context up and you end up with instructions to add a rocket to the dish. Nice try, Werhner von Braun.
And then there's when I suspect the language model google-translate uses simply removes stuff it doesn't understand / doesn't exist in English, eg. German modal particles. At least it should mark that in the output.

Yes, we have cold winters, but we also know how to make heat pumps work. Most of the installations have the heat source from the ground which has a relatively constant temperature of 7-9C independent of the air temperature. For those that use the outside air as a heat source the heat pumps are sized accordingly, and they work efficiently (COP>1) down to -20C.

There are still a lot of statistical flukes, so I find it dubious that WHO draws any conclusions this early.
Looking at it from a neighbouring country (Denmark) Sweden's policy seems uncertain. Due to difference in testing the number of confirmed cases are not that helpful. I have been following the number of deaths since it roughly started.:
Sweden had ~2 times more deaths at the start (expected - the population is twice that of Denmark).
After a few weeks Sweden had 3 times more.
After a few weeks more Sweden had 4 times more.
Now Sweden had 5 times more.

So it seems that the disease spreads more quickly in Sweden than in Denmark. Denmark enacted stricter lockdowns than Sweden early on. But it is still to early to draw any conclusions. Maybe it will peter out quicker in Sweden than in Denmark and the number of deaths will end up at the same percentages. And when I say statistical oddities I mean the numbers are high in the capital (expected) but also surprisingly high in one of less densely populated counties (source: https://www.ssi.dk/aktuelt/syg... )
