I 100% agree, but my mother made the decision not to teach myself or my brother any Estonian when we were young as "there was no point as at that time it seemed Estonia would be part of the USSR forever and you'll never go there anyway". My Dad disagreed with this approach, but went along with it; it's one reason they're still married. :)

When my daughter was born she was gifted an abacus by my brother. She loves to play with it because of the colours of the beads and the sound they make.

I was looking at it at some point and realised that when you use the beads as numbers, rather than counting them, you can go incredibly high. I must have known this earlier in life, but I completely forgot about it. After this I heard a lot about the benefits to learning maths with an abacus versus learning how to do math with a calculator. One of the claimed benefits is that, when you learn maths with an abacus, you get better at doing calculations mentally, whereas if you learn math with a calculator you don't become better at that.

Does anyone know of a good resource to learn how to do math with an abacus? I know I can just duckduckgo it, but maybe there is some exceptionally good source somewhere?
Timeseries is the data model and that is, for the upper end, synonymous with column-oriented. In my top comment, I mean timeseries/column-oriented (there are other series besiudes time, byt they fit the same data model).

The top TS databases are more than just storage too. You need a query language that can exploit the ordering column-oriented gives you that the row-oriented relational doesn't.

On the lower end (eg, Timescale db) trying to fit a timeseries model on a row-oriented architecture which is a poor fit.

I've used tinder in the past, and I remember there were recommendations online to completely delete your account and start from scratch from time to time if you suddenly found yourself unsuccessful, to get around potential shadow bans or just having fallen in a pit of the algorithm.

> Note that deciphering type tag info in a Lisp value can be called "parsing".

No. You are still operating on the level of s-expressions, a data format. The type-tag of LET is SYMBOL.

Here we have some Lisp code in the form of an s-expression:

(let ((let 'let))
((lambda (let)
(let ((let let))
let))
let))

All above LET have the same type tag, but in terms of syntax they have a different purpose in the form above: we have special operators, variable declarations, variable usage, data objects. I can't just car/cdr down the lists and call TYPE-OF. This always returns SYMBOL for LET.

On the level of a syntax tree we would want to know what it is in terms of syntactic categories: variable, operator, data object, function, macro, etc. Lisp source code has no representation for that and we need to determine that by parsing the code.
I thought it was fairly common among tech companies to provide 100% paid health, dental, vision for the employee and dependents?

Although I don't condone the "experiments" (of which the bias shouldn't be a concern so long as they're accurately presenting the data - you can't get much more accurate than screenshots, which out of the principle of charity it makes some sense to give credence to at first glance) I wouldn't blame men for feeling bitter and loveless after online dating experience. You'll find countless men (and women, but for different reasons) feeling utterly hopeless and defeated after experiences on online dating apps. You've put yourself out there, people have seen your profile, and people didn't like you. Getting zero matches (other than bots) after a few months can cripple one's self-esteem.

If you were to complain about it, you're either hit with advice from the infamous rules 1 and 2 (1. be attractive; 2. don't be unattractive), or you'll get some advice which is well-meaning but hardly actionable. The one I see most frequently is "try and meet people at bars" (it's hard to imagine this working today, and it almost requires one to be a drinker - and even then it's harder not to come off as creepy) and "join some activity groups".

The real kicker is that many activities that you already enjoy are biased to one gender or the other (say, compsci/engineering hobbies and chess tend to be heavily male-centric in real life meetings), and it's very hard to find the passion for an activity if you started doing it just to try and find a date (and people will usually pick up on the fact). It can also leave one feeling superficial and creepy to do so.

I know many men (and some women) who've decided to give up. Men because they have lost hope on account of not having a strong enough appearance to persuade someone to read their bio, which often reeks of desperation anyway (one may be short, another may be fat, yet another may be ugly, yet another just prefers Android[0][1]). Women because they only feel valued for their appearance, or just for being a woman, rather than what makes them who they are.

I expect the problem to get worse, where online, centralized dating platforms become the norm, and when it's harder to make friends in real life, in which getting to know someone first outranks any consideration of appearances. If you're not already friends with someone, it's very easy to accept or reject on what is immediately visible - one's appearance.

His history is q bit little off. LMAX came out with the disruptor after many other financial and trading firms had already done similar (or even better) work. There were a number of very fast Java-based trading platforms at the time at various exchanges and prop groups. While LMAX may have brought some of the techniques out to the general public, they were definitely not the first or even the fastest. But they definitely did excellent work in giving a framework to place similar systems.

There's some group out in New York as I recall that has a curated singles mingling thing. Tell the organizers a little about yourself and what you're looking for, and when they have a group of people that might click they host a nice evening where the whole group shows up and mingles.

Of course, there's still plenty of potential for abuse or simply misuse, but not really any more than any personal relationship. This strikes me as being basically that meetup/date cross you suggested.

> Governments should not interfere in censoring lawful speech.

What's "lawful speech" today may not be lawful tomorrow if we go down this path. I don't want governments deciding (except in very narrow circumstances) what people are and are not allowed to say.

I really like the parent's idea that a company deciding to not provide service to someone they find objectionable is just a business opportunity for someone else. If no one wants to take up that opportunity, then the public has spoken. It's not ideal, but it's way better than a government making that choice through threats of force.
I see no reason reason to expect that this will fail to capture enough market share to justify maintaining it, and then stop providing updates, leaving its users with an insecure and unmaintained fork that offers no compelling benefit over it's better-maintained alternatives.

None at all.

Very interesting piece.

I also got caught in rabbit hole following the AAP report on ebooks sales declining.
It was an interesting ride, showing a glimpse on how much things are changing and the industry is evolving.

The entry of the hole, a report on trade books sales, with numbers from mainstream publishers:
https://newsroom.publishers.org/trade-book-publisher-revenue...

Then digging further it seems these publisher also had a series of actions to bring physical book prices down and promote them better to fight back the ebook trend, which would explain the number.

Digging much further, independant publishing has become a thing, partly due to the rise of ebook, and independant sales is said to have sharply rised. A take on this trend:

We called it RUBOUT back in the day.

When you were punching a paper tape, you couldn't "delete" a character, unless you wanted to risk cutting and splicing the tape, and good luck with not jamming the reader.

But by convention, a RUBOUT character (with all holes punched) would be ignored. So if you made a mistake you could backspace the tape and punch RUBOUT.

RUBOUT had another useful purpose. It's well known that the DOS/Windows line ending convention (CR/LF: Carriage Return/Line Feed) comes from the days of Teletypes, but what is less known is that we didn't actually just punch CR and LF. Sometimes on a Teletype that wasn't perfectly maintained, the CR and LF would not give enough time for the carriage to settle on column 1.

So we always punched RETURN, LINE FEED, and RUBOUT. The RUBOUT would be ignored, and it added a little extra time for the carriage to settle into place and not get a blurry character in the first column.

Here's a nice picture (although the discussion isn't completely on the mark):

It was not spectacularly successful. Germany continues to pollute more than France, with roughly 65% of its electricity generation coming from fossil fuels [1]. In France, nuclear power generates 72% of electricity and fossil fuels account for 9% [2]. And yet, Germans pay twice the rate of France for electricity. It is the worst of both worlds: higher costs and higher carbon emissions.

> So if you want to build energy infrastructure in 1980, sure, go ahead and choose nuclear over renewables. If you want to do it now, that choice would be crazy.

Did technology magically get worse from 1980? Did the French somehow forget how to build power plants? Nuclear energy projects were cheap during the 1980s because France built a large number of a handful of plant designs. Modern plants are usually one-off projects with a single digit number of plants built of a given design. Building a dozen of the same reactors, turbines, etc. is much cheaper than building one. Political opposition has meant that only small allocations of funds have been dedicated towards nuclear power, so serialized production has not been done recently.

I think you are mis- characterizing the European systems. I say systems as each country is different - some better than others for sure, but from what I've seen from both the US and European systems, I prefer the ones where my family going bankrupt does not depend on one of us getting seriously sick or not.
The cost of healthcare per capita is way higher in the US, and outcomes generally poorer (see infant mortality rates for example).

The state of insurance for health in the US has far reach ing, society altering negative effects too which are often not considered. My sister in law would like to stay at home for a few years woth her young kids taking a career break - but cannot as she'd loose her insurance, despite her husband's income being enough to support them, it's the insurance holding her back. This absolutely would not be an issue anywhere in Europe I can think of.

There are two parts here that are not clear, and potentially misleading for folks unfamiliar with how doctors are minted in the US. The first is the cost to the individual to become a neurosurgeon. The second is around the supply side of the health market.

First, to become a practicing doctor of any sort one first completes med school then a residency and (depending on specialty) fellowship. The med school part is more or less the same for all physicians from your GP to brain surgeons to psychiatrists. Many folks take out loans to cover med school.

The residency and fellowship parts are paid. In practical terms this means a person becoming a neurosurgeon needs no more loans or upfront cash than a person becoming a GP. (I assume everyone is familiar with opportunity cost so will leave that part unsaid)

As an aside, much of the funding for these programs comes from the public (via Medicare).

All this means, the cost of becoming a neurosurgeon is about the same as any other specialty.

As for the supply side entry to med school and selection to residency programs are the big bottlenecks.

Med schools are accredited via doctors trade bodies. This means doctors (not market forces) decide how many new folks can become doctors.

As previously mentioned, residencies are largely funded via Medicare already. However, the number of residents has been capped since 1996. In that period of time the US population has grown by about 60 million (25%).

You may have been familiar with all this, but I think the context is important for discussing market solutions to healthcare — there are a lot of distortions around the US having anything resembling market behaviors.

Sure if you want to reduce error at some cost, you can use a noise metric to identify where you should send more rays. The premise of denoising is that it's cheaper and you've already spent enough time on the analytical algorithms. Also there is a chance that the noise/variance is due to a high variance feature which (a) would have been fine to leave out and (b) causes a cascade of "noise-driven" ray tracing.

Hawking radiation is a signal, one so strong it's on the order of a large nuclear bomb when a black hole finally winks out of existence.

However if it's big enough to be messing with orbits around neptune it's likely pretty large. If it's large then the hawkings radiation isn't going to be visible.

So if it's moon mass it's going to be 0.1mm and at 2.7 kelvin or so. Earth mass is 9mm, but even colder. Generally for the orbital changes they are seeing in a wide variety of objects it seems like the mass is even larger still.

Even seeing pluto is hard, even a jupyter mass black hole is only 3 meters or so. So no I don't think we could detect it via hawking radiation.

We might however see high energy particles resulting from the somewhat messy feeding that black holes are known for. If we sent a probe it could plausibly get close enough to directly observe hawkings radiation. Pretty amazing thought, maybe we will get that lucky.
