In what way has it been handy? I happen to be getting a second passport soon.

It doesn't let you zoom out but it does let you save snippets, which you can paste into the levels. I used this a lot as I progressed (still haven't finished it either).

There's no mention of instrumentation or relaying information back to earth. If there is none, what would be the point? I wonder what can be achieved in something "about the size of a microchip".

RaoulP··on Ask HN: What is a science fact that blew your mind when you learned it?
It never fails to amuse me that any pressure or force that we intuitively feel is "pulled" by a vacuum, is only caused by air pressure on the other sides of an object.

When you see something hanging from a suction cup in your kitchen or bathroom, it's fun to imagine that the air around you is hammering the suction cup enough to keep it stuck there. With quite some force you'll notice, if you try to pull it straight out! But let some air in through a small gap, and it will help even things out.

A lack of air by itself does nothing. It's just about the net forces.

What I love the most is the character animation. Did you animate this by hand yourself?

Ah, I see you're the guy behind 3dforreddit too! I had some fun with that when it was posted here.

RaoulP··on A survey of testing techniques we've found useful
I’m a complete newbie when it comes to writing tests. But I know that SQLite is tested to hell and back, and I believe Richard Hipp (the creator) has said he spends more time and lines of code on the testing suite, than on the SQLite code itself. I hope he shares some of his insights some day.

Thank you. There is a lot here I need to read more about.
RaoulP··on After 50 years of effort, researchers made silicon emit light
Interesting - if that's the case I would imagine it make sense for some systems to feature an architecture which skips the idea of multilevel cache entirely and has only RAM connected over a photonic bus. No probing, no cache misses.
RaoulP··on After 50 years of effort, researchers made silicon emit light
Same here, thanks to you both.
RaoulP··on After 50 years of effort, researchers made silicon emit light
Is the breakthrough here about emission or transmission? Or is the physics for these two connected? It's not clear to me, between the title and the article.

Secondly, could using a "photonic" memory bus bring RAM access speeds close to cache speeds, or is the transmission distance/time not the main issue there?

RaoulP··on Taiwan's new 'electronic fence' for quarantines leads wave of virus monitoring
That's true. I misunderstood the original question.
RaoulP··on Taiwan's new 'electronic fence' for quarantines leads wave of virus monitoring
> Once I'm out of quarantine, I can feel comfortable being outside living a normal life, knowing that all known potential carriers are contained.

I feel mostly the same. That’s what I’m looking forward to after this quarantine. I’m on day 6 as well - The lack of exercise or movement is the worst part.

Actually my local contact was simply my Airbnb host. I had arranged the Airbnb only earlier that day, In response to the new travel restriction.

Other passengers provided the number of their hotel. The CDC called the hotel and (I believe) checked whether they were aware that these passengers were about to self-quarantine there.

Edit: even if you arrived without having anything booked at all, you can pay to stay at a designated quarantine hotel, though that is more expensive.

Also note that Taiwan doesn’t grant the “visa exemption” usually granted to tourists, when they now arrive from countries assessed as level 3 (requiring home quarantine). I was able to enter during a short window of time where home quarantine was instated but the new visa rules were not yet in effect. So I think it isn’t usual for the situation you described to occur.

No, you don’t. As a tourist I could get a 30 day (unlimited data) SIM card with a phone number, over the counter.

I detailed my experience in another comment.

RaoulP··on Taiwan's new 'electronic fence' for quarantines leads wave of virus monitoring
I’m in precautionary quarantine in Taipei right now, after arriving from a Level 3 country some days ago.

As a tourist, I had to provide a phone number of a contact person in Taiwan upon my arrival. They call the number and confirm it works before you even leave the CDC checkpoint at the airport. You also self report your health condition. I then stood in line for 4 hours to get a special taxi to my place of quarantine. Taking public transport is forbidden. Before finally getting into the taxi, I was sprayed all over (including the bottom of my shoes) with with I presume was disinfectant.

I was later requested to add a police officer on the social media platform Line, through which I’m now asked daily how I’m feeling, and offered help if I need anything. However I don’t think they can track my position through it.

There’s a stall selling cheap SIM cards for tourists at the airport, but it’s past the CDC checkpoint, so no tourist has a local number to provide. Perhaps they should move it upstream (and just provide the cards for free), if they want this “electronic fence” to be watertight. I’m not sure but I think I could technically go wherever I pleased right now.

RaoulP··on The Shannon Limit (2010)
If I have understood this correctly - can I equate the underlying principle of this "possibility of more efficient error correction" to spotting a typo in a text? That as words grow to sentences, to paragraphs on specific topics and so on, it becomes easier to guess from context which word should have been written, when a letter is written incorrectly?
