etatobyon Japanese pagers to issue last beeps on Tuesday, ending 50-year run

You might want to look for smartphones targeted to gamers, which usually have loud speakers, or buy a Bluetooth ringer amplifier and carry it with you.

etatobyon Nim 1.0

Today it's on sale again for $25. Just grabbed a copy!

etatobyon Nim 1.0

Not (yet) a Nim user, but another post mentioned that GC is thread-specific, so you can remove all traces of GC-types from your real-time thread(s) in order to avoid deallocations at the wrong times.

A related question is whether you can disable GC on a thread by thread basis.

etatobyon Keyhut POS: Free Point-of-Sale Software for DOS

In fact, init=/bin/bash is the traditional way to gain root into a system for which you have forgotten the password. Assuming the filesystem is not encrypted.

etatobyon Dead Malls

I see your irony, but that's actually a specific case of a more general rule. Not speaking the predominant language of the place you live in will make your life more difficult and cut you off from the people and culture around you. It doesn't take much to see it as a precursor to crime, statistically speaking of course.

etatobyon TSV Utilities: Command line tools for large, tabular data files

I recommend "gron"

https://github.com/tomnomnom/gron

> gron transforms JSON into discrete assignments to make it easier to grep for what you want and see the absolute 'path' to it. It eases the exploration of APIs that return large blobs of JSON but have terrible documentation.

    ▶ gron "https://api.github.com/repos/tomnomnom/gron/commits?per_page=1" | fgrep "commit.author"
    json[0].commit.author = {};
    json[0].commit.author.date = "2016-07-02T10:51:21Z";
    json[0].commit.author.email = "mail@tomnomnom.com";
    json[0].commit.author.name = "Tom Hudson";

etatobyon Building a Raspberry Pi 3B+ full keyboard handheld

What would be cool is putting a RPI-like mainboard and modern screen in an old PSION 5 case. Those things were built like bricks and had a great keyboard.

etatobyon exFAT in the Linux kernel

I've been using UDF formatted flash drives for a long time (10 years?) and they've been working on Windows, Linux, and Mac OS X all this time.

etatobyon Show HN: Wave-based non-line-of-sight computational imaging in Julia

> The detector elements of a camera could be made pretty sensitive, but they can't detect fewer than one photon.

Or can they?

If the detector elements were part of a quantum computer (or a quantum computing "chip", whatever that will turn out to be) they would be able to analyze all the photon paths (Feynman paths) bouncing back from the subject, even those that would decohere / collapse away in a traditional detector.

IANAP, but wouldn't a quantum chip be able to perform some amount of NLOS by analyzing the paths of even a single photon?

etatobyon Ask HN: What are you learning in 2019?

1. Deep Learning. No immediate use for it, but I feel it's an important skill to know.

2. Powershell (on Linux.) I'm already proficient with the traditional shells, but I want to see if this is overall a better CLI and/or scripting environment than, say, Fish. (This was prompted by the recent post about a similar thing newly implemented in Rust.)

3. APL, getting back on it after a long time and potentially writing my own compiler and dialect, if I feel inspired.

4. Consolidating Japanese, mostly the spoken language, because I don't have the time nor will to memorize 1000s of characters. I'm already intermediate level, so at this point I mainly watch movies / shows every day, hoping some of the vocab will stick to my mind.

etatobyon Write your own Excel in F# (2018)

Nowadays, wouldn't you just use org.apache.poi for such a task? It can load an Excel file, fill in the input data, and retrieve whatever output data you need, evaluatong and caching formulas as needed.

etatobyon What’s the Difference Between Copenhagen and Everett?

I highly recommend Eliezer Yudkowsky's Quantum Physics Sequence (of articles):

https://wiki.lesswrong.com/wiki/The_Quantum_Physics_Sequence

According to Everett / Decoherence interpretation, as explained by Eliezer, atomic or subatomic particles are not physically real—let alone macroscopic objects made with them.

What's physically real is the single amplitude distribution over the infinite-dimensional mathematical space of all possible joint configurations of all the particles in the universe. This distribution—as well as boggling the mind—is complex-valued, continuous, differentiable, and evolving with time according to the well known QM equations. Crucially, it may be more or less factorizable over any given subset of its infinitely many dimensions.

"You" and "me" are just two (more or less) factored subspaces of The amplitude distribution.

Therefore, the question of where do the Born probabilities come from (an open question in QM) is shown to be inextricably linked to an understanding of the physical basis of consciousness (another big open question.) The Born probabilities may represent the "amount of consciousness" (of "you", the observer) that is split among newly factored subspaces, every time "you" get further fragmented, aka. decohered, aka. "entangled" with new blobs of amplitude.

I cannot recommend Eliezer's series of articles highly enough.

etatobyon NEC shows ‘flying car’ hovering steadily for minute

I personally prefer the Williams X-Jet or "flying pulpit" from the 80s:

Pity it never went into mass production. We should crowdfund a modern version!

etatobyon Apple suspends Siri response grading in response to privacy concerns

> requiring explicit consent for otherwise innocuous things […] numbs people for explicit consent on actually important things.

I know HN is not the right place for tinfoil hat conspiracy theories, but that sentence gave me shivers, thinking it could be the real reason those cookie consent shenanigans were mandated in the first place.

It's probably not, it's probably just a power game between the EU government and US companies. But still.

It's basically ice, fruit pulp and sugar, blended together.

I'm not aware of any iOS-based VR headsets.

They are probably not targeting the el-cheapo cardboard variety.

etatobyon I was wrong about spreadsheets (2017)

That's by design. People don't want to be "guided to better design," they want to get their math done and over with, leaving some trace (the Excel sheet) for the next time they or somebody else needs to revise that math.

etatobyon Developers don't understand CORS

State-changing GET handlers are against the HTTP concept and specs and are trouble waiting to happen. Each and every one of them were designed and implemented by incompetent and/or inexperienced developers.

etatobyon The Riemann Hypothesis Says 5040 Is the Last

Yes. In fact, if we ever manage to build a quantum computer with a non-trivial amount of qubits, we can expect exponential improvement in the performance of any prime number-related numerical research.

In fact, the expensive "gaming chairs" that popular kids buy nowadays to flaunt online always looked like car seats to me.

Not futuristic enough.

The future of rooms is they will be more like cars than rooms.

etatobyon In Japan, a growing number of car-sharing users don’t rent cars for driving

They probably aren't talking about the ones used as love hotels on wheels. They could even be inflating those other niche uses in front of the media, in order to distance themselves from that other use.

Also, the delicious boxed lunches sold everywhere, combined with the social stigma about eating them anywhere that is not a private space or a space already devoted to eating.

etatobyon In Japan, a growing number of car-sharing users don’t rent cars for driving

There can be many reasons (house not being yours, etc.) but one of them could easily be cultural inertia.

During the first half of my life, very few people in my country (Italy) had AC in their homes. It wasn't until the recent high temperatures, which only became obvious 20 years ago or such, that everybody started installing them.

I can't find a historic chart specific to my country, but I suppose it wouldn't be too dissimilar from this:
