If you mean "representing values as a pair of integers P, Q, such that the value = P/Q", the answer is that they're very expensive to work with. You generally need to be using arbitrary-length integers for P and Q, because the values get very large very quickly. And as the values get large, operations like finding the lowest common multiple (required for almost any operation between two rationals) get expensive.

As an example of the kinds of runaway increase in P and Q I'm talking about, consider calcuating the sum of x/(x+1) for values of x from 1 to 999, using python's fractions module:

>>> sum(Fraction(x)/(x+1) for x in range(1000))
Fraction(7075502361382798268120793110090229940258706389605508780354900641905867818691614397718938054011886551220308728288024788414601821895503124242001568659978565050184167864774563757893457200995977901194872761682228965032590045181707202517783731540396927542180527680245723964874429994374505238893797078720320991788231820649513569449454767125309918934132672543174716802507966087781714014833406311821646176291230132112749836042537756095388477483, 7128865274665093053166384155714272920668358861885893040452001991154324087581111499476444151913871586911717817019575256512980264067621009251465871004305131072686268143200196609974862745937188343705015434452523739745298963145674982128236956232823794011068809262317708861979540791247754558049326475737829923352751796735248042463638051137034331214781746850878453485678021888075373249921995672056932029099390891687487672697950931603520000)

That's a 436-digit P and a 433-digit Q.

Rational types like this can definitely be a good choice in a use-case where accuracy is important, and operations do not compound. But they're a poor default, which is why we generally see float types as the most common non-integer number representation.

> I was hoping Amazon was actually making housing for its workers.

In the movie 'Sorry To Bother You' by Boots Riley, they have an Amazon-like entity called 'WorryFree' that does exactly this.

I'm not sure we actually want this (Amazon or other big employers making housing for laborers they employ), especially since these workers are often not labor aristocrats, and therefore will have little bargaining power.

No, marketing is the study of markets, and the study of markets is very similar to hacking. You find a need or necessity of a market and look for a solution, sometimes it is even a technical solution to the need and you are properly hacking.

Marketing is not sales, it is not copywriting, it is not setting a motto. This comes at the end when everything is known about a market. They are executive decisions that could be done by the marketing department, or not.

Most of the time small and medium company owners contact copywriters directly for example.

He wants everyone to suddenly stop using money. If that happened, who would wash the dishes?

Many communes have failed over this exact issue. They go on for several years with several people, usually women, making the sacrifice and doing what needs to be done. But eventually, the people who do the dishes get fed up and stop, or leave. And then the whole thing collapses.

The alternative is for the leaders to have some type of power to compel people to do the dishes, and some type of punishment to mete out.

There are certain tasks in society that no one wants to do. In order to get them done, you have to choose the carrot or the stick. Money or punishment.

If the society has no money, there's going to be a whole lot of punishment going on. It can work in theory, but in practice, a society based on punishment tends to snowball out of control, with the people in charge of punishment going too far. The people in charge make a small mistake in the size of punishment relative to the transgression. With money, small mistakes like this happen constantly, and they are constantly being adjusted by changing prices and salaries. The garbage man makes a higher salary than other manual laborers. But without money, the process has more steps, and is harder to get right. People protest, the leaders listen to the protests, go through the rule changing process, and eventually adjust the punishment to fit the transgression. Without money, more people are involved in the process. Some are removed from the actual issue. It takes longer for the adjustment to be made. With only the tool of punishment available, it's more difficult to fine tune every mismatch. In practice, it's really, really hard to get a punishment based society just right.
> I'm sure there's a lesson there somewhere.
There sure is: Having one goal and being able to allocate all/most resources towards that goal. The problem is that this is not sustainable. Times of crisis usually ends and then what? Then we are back at square one with "How do we allocate our scarse resources between these really important 4-5 goals?"

Concluding: It is certainly refreshing how efficient groups can be once a crisis forces all attention towards one single goal. (Perhaps unfortuntately) that is not a reliable (crisises are usually not predictable) nor sustainable (other goals tend to get neglected in crisis mode).
It's just the idea behind Test Driven Development, that tests drive development. It won't be very effective as a handover, though could be used as acceptance criterias if that is needed.

The adherents really want tests to be the specification, as a way to be measurable / testable. Specs may be converted to tests.

But most of it is theory. It all depends, as usual, on the dev(s) and circumstances.

Really, I don't care one way or the other, though for a server I'd want something with a BMC. More important to me is that the motherboard itself doesn't have any fans. If there's a little bitty fan on the chipset, don't just walk away, run.

Open source APM/exception tracking that I could self host
Hi! I have quite a bit of spare capacity in my Kubernetes cluster so I am self hosting many things.

I would like to add APM/exception tracking for my Rails apps to the list, so to save money because the paid services tend to be expensive. I see that there is Sentry that can be self hosted but it's a bit complicated with many dependencies. Is there anything simpler?
The main ones certainly are nowadays. With some regularity, our customers ask us to verify some of the software or dependencies they're using, and this sometimes includes cryptographic libraries. We would then check the parts which the customer actually uses, so not all of openssl for example, but in general yes this is being looked at. These fixes are always upstreamed, by the way, although it's up to the customer whether they want to handle it themselves or whether we do the responsible disclosure process.

The heavy and routine use of email in businesses 'going paperless' suggests that this claim has little basis in reality.
Agreed completely. I was (and still are) on couple of different companies and teams practicing "Agile" and those daily standups are more like daily blamefests. God forbid you get stuck somewhere and need someone's help. Then you have to apologize because everyone thinks that you're lazy or incompetent and holding everyone down. Also if people wanted to know what I did yesterday, they could have a peek at the tickets they want us to keep up to date but no, they want us to say it anyway. Also that stupid "do you have any blockers" question. No I don't have any blockers, it is this bullshit technology/service everyone wants to use today, and discard tomorrow which I somehow need to be an expert of with 30 min of looking at some incoherent manuals.

It seems to me, that all these buzzwords and meetings are just a way to always keep you "busy" (or at least looking busy), to always have some kind of fire below your feet so you don't "slack off" (or have a bit of free time to actually gain or sharpen the skills you need for the same company...). I'm just tired of this. In a way, good teams will be good, and bad teams will be bad, doesn't really depend on whatever process they have.

You mean 8,000 years ago, there was an age of rising seas for the preceding 10,000 years.
I suppose the name of the magazine implies this, but the amount of "concept terms" loaded into each sentence sounds so old timey, or something, to me.

"Such a relationship between the company and public goods like a high school is part of what it means to consider Amazon as “the major working-class space of suburban and exurban socialization.”

The behemoth is here, producing not only profit but people, too. That entails corporate indoctrination, social estrangement, and profound alienation from one’s labor..."

You kind of need to be steeped into the literary culture to "fluent." Reading it, it feels like I'm "looking up" the words in my memory to follow the meaning. I suppose it's not too different from the "tech talk" dialect we're more used to on HN: "disruptive potential of this novel user space paradigm" or whatnot.
The issue here is that the school is teaching not general knowledge, but knowledge that is only useful in the Amazon context.

It's a "company town" mentality. Amazon needs the workers, so it makes sure that the workers need it.

That's completely different to EU/Government funding. That's a debate between two levels of government about who gets the political benefit of the funding. However, by definition, publicly funded facilities are examples of "Your taxes at work".

I just realized. Is it a play on the phrase “I am”? If that’s obvious, it just clicked with me after using AWS for ten years.
I like the phrase "art imitating art", but it's broader than that. For example people with no interest in antique, Greece or Sparta are fans of Spartans. In reality, Sparta was a North Korea of the antique world, AND it had profoundly average combat performance. No matter how you slice it, they were completely average as far as won battles go!

https://acoup.blog/2019/09/20/collections-this-isnt-sparta-p...

If you filter out naval battles, it doesn't change anything. If you remove battles where they fought in a coalition with other Greeks, their win rate even drops slightly.

There is some evidence they may have had a slight advantage in leadership, because they had more leaders and their units were a bit smaller so they could perhaps operate more independently and seize opportunities on a field of battle (a strategy perfected by Romans). But overall, their strategy was bad even by antique standards - check out the Peloponesian War (with Athens). Spartans just had a good PR.

Dead butterflies is a meme (in the old meaning of viral idea). Spartan military excellence is a meme too.

> This tries to reduce it to a scheduling problem, but reduces too much.

I didn't read his remarks as scheduling. More like being in control of your time is being able to choose what you do, not be told what to do by someone else, or do things to please or satisfy someone else. It is a reverence for independence, which I imagine comes with or arises from wisdom, skills and wherewithal. Or luck. Whatever. What he values is freedom as much as agency.

Completely different use cases. Sidekiq is best for decoupling workers from producers that are in different interpreter contexts and possibly different machines.

Ractor is for parallel execution within the same interpreter context. Much lighter weight, but also with no persistence.

EDIT: Basically consider Ractor for places where you might want parallel execution, want less data sharing than with Thread, but don't want the overhead of a process-external job system.

That's fair, except for utility in my usage Windows runs less of the programs I want.

I think a clearer way of putting is this: types are not a mathematical notion.

So "Bool" is not the same as "{On, Off}" nor "{0, 1}" nor "{Up, Down}" etc.

We can reduce a type to a set of all constructible values; likewise we can reduce english to the "big infinity" of all possible sentences expressed in all possible universes. But english isnt this set.

If one had this set, E, then you could reduce the question of whether a conversation (C) is valid english to set-membership, "is C in E?" but this misses whether the conversation is actually about anything.

Likewise "me" can occur in an infinite number of sets (Person, RandomObjectsOnEarth, ...), but that "me in Person" is the "valid question" has nothing to do with "me in Person" -- and everything to do with the semantics of me/Person. "Person" is about "me".

It is for this reason that values have "principal types" in programming languages; ie., the "set" which happens to be about the value.

Insofar as mathematics is employed to model reality we have to introduce non-mathematical devices to constrain its application, types may be understood as the formal mechanism to do this.

The world is full of examples where literary cliches have more influence on our biases and expectations than first or second hand experiences. We rarely observe other people falling in love, but we see it in movies and stories all the time.

In cases where people simply have to follow instructions, I find the fear of the command line to be disappointing. It is far easier to provide support and that support is far less failure prone simply because you can state exactly what has to be done, rather than describe how to navigate a user interface while hoping that the other person interprets visual cues in the same way.

That being said, there is a deeper problem with the Arch installation process: the user needs to know exactly what they want. I can race through an Arch installation and end up with my desired configuration far faster than I could in any other operating system. Much of that has to do with the ability to dump a list of package names into pacstrap and copying over a bunch of configuration files. There is no fumbling around with a GUI. Yet those who are new to Arch (or, worse, new to Linux) don't have the benefit of that experience. The process is daunting.
At the end of the article:

>> The problem remains that fully solar balloons need sunlight, and it is rare for the sky to remain unclouded for long journeys.

Above 6,000 metres, it is rather rare that any cloud blocks the sun in daylight hours. This method of transport has potential for freight.

Rather than black, you'd want a transparent skin or layers of skins. Focus sunlight with internal reflectors onto an engine. Usefully, waste heat is not a problem here, but valuable, when captured in the envelope.

The engine should use more than just heat energy. Visible light for PV power generation. Maybe ultraviolet can be used to elecrolyse environmental water vapour to hydrogen. To provide both lift and energy storage for night time.
Twitter is a cesspool with islands of high value. The cesspool is tolerable because you don't have to swim in it once you've found some decent islands.

I'm guessing the others are similar, but I don't use them much.

The problem appears to be that most social networks get to a stage where they've saturated their potential markets enough that their only way to grow is to find ways of growing engagement, and one major way of doing that is to try to get people to interact more with each other.

Unfortunately that often trigger actions that are completely counter-productive, in e.g. trying to push content people don't want across the islands, and in doing so reducing the value of the platform to users. You may get short term boosts in engagement but long term rot as people are less happy. E.g. see the frequent complaints about Twitters algorithm and how they try to avoid you sorting content chronologically.

[incidentally I have a code base I used to do very basic bayesian filtering and ranking of tweets, as part of a bot; it worked very well at surfacing better content, so sorting the good stuff from Twitter is possible. But I got other things to do and also had concerns about investing more time in anything that relied on the good will of Twitter to keep working...]

Youtube will be fine, it is a pretty good platform as long as you aren't looking for political opinions.

And Apple has historically been very methodical about closing down opportunities to compete with their products. The only part of the market they leave open is the part that has no money. There was a truly funny span of time when the iPhone accounted for more than 100% of the phone market because other mobile manufacturers were making losses. The Zune never had an obvious market segment that it could target.

At the moment, anyone trying to produce right wing content would have to be mad to be comfortable on the major platforms. Even Amazon seems to be unreliable after what looks a lot like a political hit on Parler. There is a large, obvious & dissatisfied group to target here and potentially a valuable advertising market.
