Recruiting Agencies: The Good, the Bad, and the Ugly
Sure, the logic of the sigils is easily broken, but that just brings us back to every other language, with the added noise of the "$" sign (so pretty much to PHP).

As for implicit variables, I rarely see anything else than $?, $|, $_ and @_, of course. And I'd argue that $_ often makes code a bit easier to understand than cluttering it up with a variable declaration. No worse than point-free programming in more modern languages.

Don't get me wrong, I don't think that Perl is that well architected and that Perl5 would've required some more courage at dropping backwards compatibility, but what I don't get is why Perl is singled out here. It's not that radically different like e.g. APL or ScalaZ.

Compared to other languages of its day, this feels a bit like the "Reformed Baptist Church of God, reformation of 1915" joke. Then again, perfectly fitting into similar conflicts about brace styles or 1-based indexes…
I'd argue that Kotlin is still a "Upcomming programming languages" - and I think one of its reasons for success is how well integrated it is into the IDE. (especially if you use intelliJ)
https://arxiv.org/pdf/1803.04014.pdf - no matter what they did, they could not go beyond 83TFLOPs in fp16. And that's just matrix multiply. Any kind of deep learning workload is going to be a lot slower than that.
The same applies for other tooling as well; one of the reasons why go is so popular.

So moving charged particles in vacuum produce photons on their own. How do we know there are photons produced and not something else with right energy that happens to act on our sensor?

Specifically, the sensors that use photoelectric effect do not react in the right wavelength, while standard radio sensors are also sensitive to charged particles. And presumably also use this exciton/pi-tons interface.

How can we exclude it? Presumably fire photons from putative EM field at neutrons, observe emitted photons with wavelength change? (Essentially Compton scattering experiment with neutral particles.)

My whole problem here is there's a lot of "seems as though" in those experiments... Like when you try to measure center of charge with it.

Absolutely yes. It's true of all organizations, but I've found that with non-profits especially, just figuring out the need you are trying to address is quite difficult.

It makes me think of all that uproar for some iPad app for the TSA that just randomly showed a left or right arrow to send tell people which line to get in. Surely easy to code. But I bet it was months or years of interviews to determine that's all they actually needed.

I think another problem with these horrific ERP's is that their tentacles are everywhere in the org.

Oracle EBS, my personal "favorite", runs PLM (product lifecycle management), inventory, order management, work orders, customer install base, finance, purchasing, AND PTO entry, F.M.L. !

We can't have nice things in, say, PLM because the whole damn system is tied up tight as "modules" in Oracle EBS. Any kind of change or request involves, at a minimum, harassing a overworked guy in India who is constantly dealing with battle-axe personalities in finance and order management.

Things that SHOULD be taken for granted, like being able to create a hyperlink to the bill of materials for any part number-- that's seriously impossible, it's like a freaking moon shot for them (or so they say).

You can use some of those crowdsourced lists of hosts files to ban trackers, ad networks, and the like, i.e. https://github.com/StevenBlack/hosts or https://github.com/notracking/hosts-blocklists, you can use pi-hole even as a docker container https://github.com/pi-hole/docker-pi-hole or install it in your router.

You can use Tails, which uses 2 VMs.

First thing is to stop reacting emotionally to the jerk but rather rationally. Ask yourself why the jerk behaved the way he did. One could easily reason that it's not uncommon for the interviewer to talk down to an interviewee because they are looking for a job.

As such, the interviewer feels like they are in a position of power. This is why top tech companies often make the interviewee do a lot of work and go through the rigorous process of multiple interviews before getting hired. They feel like they can do that in their authority position. However, this doesn't make it right.

People who abuse their power shouldn't be in their authority position. An abuse of power is when they use their position to feel superior to others. It's likely the jerk has low self-esteem and was taking advantage of his position to feel superior to the candidate. Such people do not belong in authority positions. I would speak to your boss about his behavior and recommend the jerk not be the interviewer anymore for the reasons stated above.

> That's a pretty big negative spin on the "free + ads or pay" business model. Isn't that the model we all want? We all complain about ads, but what alternative is there other than to pay money?

That's a good argument! I admit that I fully support the free + ads business model.

Thinking a bit more about this, I believe what irked me about the YouTube experience is (1) that I was repeatedly (ad nauseam) shown the very same ads, and (2) that the frequency was continuously increased to the point where the free+ads version was no longer watchable.

I already expressed what how I feel about (1), and (2) just feels like the wrong kind of pressure, because it impairs the product.

Here are two alternatives to (2) that I would have considered more effective: (A) mark a channel as "favorite" and watch those videos with zero ads, and (B) watch the first 100 videos a month with zero ads.

In both of those cases, I can see someone meeting me half-way. In its current form, it's just increasing and increasing the level on nagware.
The way I think about lift is that at a certain point, the air can’t get out of the way fast enough, so lift is created. If you’ve ever skydived, you know the air at high speeds feels thick —- slight deflections and imbalances produce drastic movements.

> It's not that radically different like e.g. APL or ScalaZ.

Both of what never got as much popular.

Perl is singled out because it was used. And too often on short scripts that grew into thousands of lines, so the problems showed up.
> The problem is that garbage collectors are optimized for applications that mostly have short-lived objects, and a small amount of long-lived objects.

I think it's not quite that.

Applications typically have a much larger old generation than young generation, i.e. many more long lived objects than short lived objects. So GCs do get optimized to process large heaps of old objects quickly and efficiently, e.g. with concurrent mark/sweep.

However as an additional optimization, there is the observation that once an application has reached steady state, most newly allocated objects die young (think: the data associated with processing a single HTTP request or user interaction in a UI).

So as an additional optimization, GCs often split their heap into a young and an old generation, where garbage collecting the young generation earlier/more frequently overall reduces the mount of garbage collection done (and offsets the effort required to move objects around).

In the case of Go though, the programming language allows "internal pointers", i.e. pointers to members of objects. This makes it much harder (or much more costly) to implement a generational, moving garbage collector, so Go does not actually have a young/old generation split nor the additional optimization for young objects.
This is some Java-level explicitness. Maybe, drop the `_seconds` suffix and replace it with something like `retry_window_after_first_call = '60s'`?
There are obvious cases of deceptive media, where things are simply made up, but the most invidious ones are just "differential spin" and very hard to pin down.

> There is little, if any, serious disagreement as to what the appropriate equations or their solutions are. The objective of technical mathematical theory is to make accurate predictions and to project results that are useful to aeronautical engineers engaged in the complex business of designing aircraft.

> But by themselves, equations are not explanations, and neither are their solutions. There is a second, nontechnical level of analysis that is intended to provide us with a physical, commonsense explanation of lift. The objective of the nontechnical approach is to give us an intuitive understanding of the actual forces and factors that are at work in holding an airplane aloft. This approach exists not on the level of numbers and equations but rather on the level of concepts and principles that are familiar and intelligible to nonspecialists.

It's funny to read this after many years of teaching myself to think "mathematically". The situation described above is in some ways the true mathematical ideal: to be able to describe our surroundings so precisely that intuition and perception blurs away, giving way instead to something stronger than what we can describe in human words. When you describe something to two different people, the objective is to adapt each explanation to their personal framework, much in the way an artist or musician would adapt to their audience.

However, the objective of mathematics is to take away exactly that: the variability in perhaps equally valid social or human explanations.

I do think that intuition and perception is a very important of mathematics, but I think it forms the first steps of the scientific method behind mathematics. Identify perceptions and intuitions and after that try to get to precision and rigour.

Mathematics aims not to be intelligible, but it is in fact a fortunate state of affairs that mathematics is intelligible to humans at all! It reminds me of what Eugene Wigner wrote about mathematics, titled The Unreasonable Effectiveness of Mathematics in the Natural Sciences. [1]

One thing that should be more clearly stated in the article is that it esentially claims that the mathematical descriptions themselves seem somewhat incomplete, the explanation of which I don't know, as the article tries to avoid mathematics in the first place.

I think much of the fear surrounding monosodium glutamate (MSG) simply comes down to its common name being a chemical. Imagine saying "pass the sodium chloride" at the dinner table.

Meanwhile, in Japan, MSG is commonly referred to by the brand name "Aji-no-moto", which means "essence of taste." It can be found in most households.
I have experience with VHF radio emulation, so I wanted to ask what formula you're using for ranging?

Given how extremely useful public key technology is, I certainly hope that P ≠ NP (as well as the stronger BPP ≠ NP).
That is a fair point, but to be clear, it does nothing to rehabilitate the notion that Newton and Bernoulli provide independent components of lift that have to be added (or, for that matter, that one is right and therefore the other is wrong, which is another common misunderstanding that has shown up elsewhere.)

These foods have comparatively high levels of MSG: tomatoes, seaweed, parmesan cheese. Think of what makes them taste different compared to other food. MSG by itself has quite unpleasant taste IMO, but it tends to enhance other tastes, making bland-tasting food have a more pronounced palette.

The "Equal transit time" is one of the "lie to children" explanations of lift. In fact, classic wings depend on inequal speed caused by a vortex behind the wing - which is also an oversimplified model. Such "bootstrap" vortex causes an opposite vortex to form around the wing, giving difference in speed of air on both sides. Once you have the airflow in the right way, Bernoulli's principle gives you lift.

That's the very simplified version of a simplified explanation used in aviation teaching materials :)

At it’s core SAP as it is used in most companies nowadays is mostly just a database of clients, vendors, invoices, purchase orders, and inventory, with a UI for CRUD operations.

Business decisions are usually made on exports in third party tools (Excel, Tableau...). Why is not disrupted yet then? For me it’s the same as Oracle for database engines and IBM mainframes: enterprise sales process and trust in proved decades solutions when you you bet your whole business in a software or hardware solution.

Afaik, all genocides involved a lot of torture - both of targets and of those who refused to cooperate or talked against it. Sometimes it was to gain information, force agreement, force compliance etc. It also involved quite a lot of petty rule making to keep those who were being oppressed in line.

And quite a lot of it was basically for fun or hate.

Besides original quote is about motivation. People who organized genocides were fully ok with their own conscience. They were in fact proud over their own good work.

And as fun it sounds and as easy it is to use against certain disliked people, it is not true in the sense of how world really works when things go bad.

I teach enterprise systems at a university, with emphasis on SAP.

It's hideous. Hideous. My students complain it is unusable (agree), doesn't make sense (agree), that they can't see the point (agree).

When you look at the underlying database 'schema' (inverted commas deliberate) you'll find it's a massive, denormalised mess.

Much of what SAP can do can be done at the local level using intuitive software. Reports, for example, against a well-designed schema or data warehouse are easy. Power BI, Tableau, whatever your poison. You can even aggregate and present data in raw SQL if you like. Each technique is far easier than trying to achieve the same in SAP.

What SAP does do well is multinational, enterprise-wide integration. Are you a company comprised of many mergers and acquisitions? You can do HR one way, universally, across your organisation. Credit control? Replace your spreadsheets and custom apps you have deployed across your many siloed finance departments with the FI/CO modules.

I (am actually told to) teach that changing the business to fit SAP is preferable to changing SAP to fit the business. And it's accurate advice. It shouldn't be, but it is. SAP is SAP. It doesn't care about your USP. Or your custom approach to business. As far as SAP is concerned all businesses are the same, they do the same things, and all must conform. Resistance is futile.
