This was posted before in a different form, but I think the discussion became a bit one sided and went off on a tangent. So there is a few point I would like to make about this practice in Sweden:

1. As the article states this is an old practice. There used to be an even better scheme around 10 years ago when you could get unemployment for a year by having someone unemployed replace you.

2. The primary benefit, since is not paid, is that you can keep you employment i.e. you can't be fired. But for every year this is less of a given as more and more people have temporary employment, work as contractors, at smaller firms where different rules apply or are granted lesser rights under the law.

3. In Sweden you are required to be loyal to your employer. Which means you aren't allowed to start a competing business while being employed or for some time after and retain your rights. Which also means you can't for this scheme either. This makes the whole thing useless for most people in technology.

4. Living costs, and centralization of society, are off the charts in Sweden. You will be bleeding money fast unless you are already rich.

So I think there is very little real benefit to this.

Edit: Pretty lame to mark this story as a dupe though, now this comment is pretty much meaningless since the primary motivation was discussing the issue. I guess the "middlebrow dismissal" would have been a better idea.

I'm indifferent to the policy, but one possible way would be conditional employment linked to the return of a sabbatical employee being replaced, or perhaps a fixed probationary period allowing for release without cause.

The A380 is probably quieter than its competitors. And further, if there are less flights with A380s carrying 400 passengers, then there will be more flights with alternative planes carrying 200 passengers. Those 400 passengers are still going to fly.

Fewer A380s mean there will likely be more planes flying overhead, and each one is likely noisier than the A380.
Thanks! I had a look, but there isn't much information about them. I'll first try solutions that have more info published.

> Not sure I see your point with this example - isn't a resolver like this just a fixed database of entries?

Until you get to how well it handles misspellings and incomplete information. Addresses are also notoriously difficult to parse. There is some logic and ranking at work behind the scenes. The only times I've seen it consistently fail are when the city is incorrect, or it's a genuinely new address (new construction or address renumbering).

In any event, is a read-only service somehow less of a service? I'd wager read-only services see a lot higher demand than anything.
> NYC to London

No A380s on this route. There are 32 flights each way, 28 from Heathrow.

BA/AA operate 12 daily flights LHR-JFK, pretty much one ever 90 minutes during the day, it's pretty much a turn up and go service. Virgin/Delta do another 8 flights, again turn-up and go.

That frequency attracts the people on flexible tickets. Those on the cheapest flights they find on skyscanner will probably take the norweigan 787s from Gatwick.

That market for flexibility doesn't exist between say London and Singapore (I suspect most are transferring at least at one end), but there's plenty of passengers looking to travel, and so you get 4 of the 7 flights over 3 carriers are on A380s.
You have to deal migrations maybe 1/20 the times than with SQL. Like no migrations for new tables, new db, and new columns. Column name changes can be handled on the application side or yes with a migration.
I agree to an extent, but it's important to realise such rules aren't "free."

There's a cost to holding someone's seat. Employers whole heartedly replace them, because they're entitled to come back. So, they need a small 6 month replacement that may or may not become a permanent need.

For most jobs at large companies, I totally agree. They should be able to handle it. But, marginal cases will still exist. Niche roles, senior employees or smaller companies. Image a 200 person startup where a team lead or similar takes her 6 months. The team is now in limbo.

I like the idea, just saying it comes with downsides too.

The person is still employed so still has the same protections as if they never left. It's very hard to fire someone in Sweden so that is important.

Its fair to say that the EU is not generally seen as a big democracy, but as a large administration that lives in the background, kind of like NATO or the UN, so people don't expect to engage in EU politics in the same way they do with national politics. It is more problematic for example that the reasons why with the EC is proposing the laws are not clear, rather than why the MEPs voted for them.
Ask HN: How do you end a non-winning argument in your PR professionally?
Getting in a pointless PR argument is one of the soul crushing reality developers face everyday.

When discussing a certain discipline, be it mathematics or any other, the issue of rigor and foundation are completely separate. Rigor is established if you are careful to always follow the axioms determined by the foundation. But the foundation, i.e. the choice of the axioms can only be established in another, lower level, discipline, which, in the case of mathematics is philosophy.

In the early decades of the 20th century there were furious philosophical debates about the philosophy of the foundation of mathematics (between Brouwer's Intuitionism and Russell's Logicism, and also Hilbert's compromise of Formalism), but they all stemmed from an underlying assumption that mathematics gains its validity from some notion of philosophical truth. One could argue to no end on how the truth of mathematics is established, but a different perspective later emerged that avoids this debate altogether: that mathematics takes its validity not from truth but from utility (which is always relative to a specific task). We cannot say that one of those views is unacceptable, and if your position is that mathematical validity stems from utility, we cannot tell you that your foundation is shaky if its utility is established.

I have just got an old iPhone from a relative for my convenience, and blown away. This is not a new thing. Google, somehow, have been getting away with this practice for many years now. To me it seems as extremely foul, and I just cannot understand, how?
Thanks Nathanlee, it’s great to hear about your experience in FMCG and some of the challenges you faced around A/B testing layouts and integrating sensors, I’d love to pick up a conversation with you about this.

We’re currently focused on speciality retail, especially where the store is more of a ‘show-room’ style such that product layouts and window displays can be more easily configured. We’re also considering partnerships with camera manufacturers as this is on our roadmap, but not mandatory at this stage as we integrate with any IP-camera system.

In general, I like it. I think the syntax is a bit messy though.

λx.x

is much cleaner than

{lambda {x} x}

Don't want to use λ? Consider

\x.x

For your special cases of multiple args, consider

λx,y,z.(x z)(y x) // S combinator

For nullary functions:

λ().M

Last, this is really more a lisp than a λ-calculus. Difference is subtle.

I find that kind of arrogant. In a lot of cases, the UX designers simply underestimate the real complexity of a task.
I got to experience first class in a BA A380 flight once since it was cheaper than business class and my company was paying.

This is probably going to sound like the pinnacle of first world problems, but: it's overrated. The main differences between business and first were getting actual bedding and having more attendants per passenger. And three types of champagne, because obviously just one isn't enough. The food was slightly better than in business but nothing outstanding.

There's a huge step up from economy to business since you get the lie-flat seats you can actually sleep comfortably in and good food/alcohol. Beyond that, you're mainly paying for exclusivity and status.

Denormilization is not the thing because normalization of data in document db just results in what will heavy denormalized SQL. Like the address fields will be document inside the document. Instead of user_address_1_zipcode, you’ll get user: addresses: [ { zipcode: ... } ] }. It seems more elegant to me. But, yes you do have to update everywhere manually.
It's enforced by the state. Simple as that.

If the company want to let you go for not being needed any more they need to follow the last in first out rule for similair positions/qualifications and if you are that person the company has to give you x months of notice and pay, but I'm not sure what happens if they do that during a leave.

The acceptance of this declaring people as "horrible human beings" by mostly anonymous decree, and then creating a fashion where "the worst thing this did/said" is brought up by people who are X degrees removed from even that, every time the unperson does or say anything, I find much worse than being a caustic prick, which at least is hard limited to the actions of one person. Even if the person should be really bad every now and then, they're already sometimes just kinda-bad-mumble-mumble -- and the habit that is being formed here is just waiting on being used on all sorts of people.

Slightly tongue in cheek, but the analogy to programming is this:

The problem is that it is difficult to translate results in a theory built in ZFC to other "architectures". In mathematics, the architectures in question are not different axiom systems, they are different branches of mathematics.

Let me give you an example. There is a large body of work on differential geometry with many useful constructions. Classical differential geometry works directly in a model where manifolds are certain subspaces of (countable products of) R^n. These constructions have been successfully imported into many different areas of mathematics. In most cases people just had to tweak the definitions slightly and adapt the proofs by keeping the basic strategy and changing all the details.

What is happening here is that the underlying ideas of differential geometry are not specific to this particular model.

When faced with such a concrete model, our first instinct should be to abstract from it and ask which assumptions are required. This is difficult in ZFC, because in the end you have to encode everything into sets. It's not possible to reason about "abstract datatypes" directly, without literally building a notion of logic (generalized algebraic theory) and models of it within ZFC. Even then, the existence of choice means that you usually have to exclude unwanted models of your theory.

Coming back to differential geometry: You can generalize a lot of it by working in a differentially cohesive (infinity-)topos. This is terribly indirect (in my opinion) and looses a lot of the intuitions. A topos is literally a model of a certain logic. Alternatively you can work directly in this logic (the "internal language" of the topos), where the differential geometric structure is available in the form of additional logical connectives. You are now talking in a language where it makes sense to talk about two points being "infinitesimally close" and where you can separate the topological from the infinitesimal structure.

At the same time you reap the benefits that there are many more models of differential cohesion than there are models of "R^n modeled in classical set theory". You can easily identify new applications, which might in turn suggest looking into different aspects of your theory. It's a virtuous cycle. :)

This approach is deeply unnatural when working in set theory or arithmetic. You have to encode everything into sets or numbers and then these sets or numbers become the thing you are studying.
Or just more small planes. Or new, hyperlocal airports.
I think it is important to remember that the number of nuclear-related deaths is unrivalled compared to the mortality from oil-related conflicts or mortality from coal pollution. Mortality per kilowatt for electrovoltaics is very high due to accidents during the installation of solar panels on roofs. Germany is certainly not a good model on this.

I have to assume that there is also a policy to prevent firing them as soon as they get back from leave, or else the whole thing is useless. I also have to assume that a replacement hired has the same rights as the employee who took leave. So there could be successive waves of sabbaticals.

This policy would instantly destroy Silicon Valley. I can picture companies with more employees on leave to start startups than actual working employees of the company!
That is a lie.

According to the WHO (https://www.who.int/ionizing_radiation/chernobyl/20110423_FA...), a "large fraction" of 6000 thyroid cancer cases (to 2005), of which 15 were fatal, are attributable to radiation exposure. No other health impacts are supported by evidence.

As such, the actual figure for deaths (at present, over 30 years since the incident) resulting from the Chernobyl incident is somewhere between zero and one per year.

Even if it was thousands of deaths per year (which it is not), that would still be far below the number of deaths caused by burning coal.

The whole point of "special education" is that it does things that don't scale to everyone (so it involves guessing who's going to get the most benefit from it, and these are the students you regard as "gifted"-- although in practice commitment and "grit" are a lot more important than supposed aptitude). Individualized teaching for each student, with a "mastery learning" model (i.e. no fixed time-based curriculum; you keep working near your current level in any given subfield until you achieve mastery at that level, then move on) is what gives the best results, but it can only be achieved practically via computer assistance.
