Ask HN: How to determine grumpiness in job candidate?
New experienced hire (30+ years old) passed the interviews, with a few odd remarks about some software/companies that didn't trigger red flags for us. The criticism seemed misplaced but understandable.

After the welcome phase, where we showed him all the challenges we had and how much work was left, this became his common behavior:

- Excessive sighing when exposed to technical debt

- Switching between patronizing attitude and aloofness

- Sarcastic comments about internal processes (or lack of); as a matter of fact, about everything that gets discussed.

This is a team where members have total freedom to identify opportunities for improvement and carry them on. We have a flat structure (there's a manager on paper but the team is expected to work things out).

We were expecting, due to his experience and our clear indication that there was a lot to do and many projects would be greenfield, that he would be more excited about the work.

The thing is, he has always worked for small companies or startups, where one is supposedly used to lack of hierarchy and getting things done. So this attitude caught us by surprise.

I feel the extra grumpiness and the flood of technical challenges broke him. Some have theorized we were too extreme when presenting the situation and should have let him discover things by himself instead. The fact is, all of that can be fixed and we were hoping to speed the process up, because we knew what needed fixing (but didn't have enough time, thus the hiring).

How to better spot this during the interviews? Is grumpiness the issue here?
> trusted browsers to scroll

This is especially egregious on mobile, where not only they implement scrolling badly in a way that only vaguely matches a single device/os (with terrible performance) and is completely off on others, but also feel compelled to hijack scrolling for "creative"† navigation, like swipe left/right to move across articles, which gets triggered every time you scroll downward but ever so slightly sideways. Like, I'm on a bus and actually holding the phone, so don't zap me to an unrelated article I don't care about on each encountered pothole please.

> Time dilation isn't just speed, it's also acceleration.

That's not correct. Gravitational time dilation isn't a function of acceleration, it's a function of gravitational potential, i.e., how deep you are in the potential well of the source.

(Also, an object that is in a free-fall orbit has zero acceleration in GR, since in GR acceleration is proper acceleration--what is measured by an accelerometer.)

It's true that the usable screen area shrinks. It also shrinks with sticky headers or similar... If that's a problem, maybe add some Javascript to make the headers optional?

Or just don't do "frames"/"overlays"/"sticky". That's still better than messing with the global scrollbar (like Twitter does for example) and totally wrecking user experience.
"You can smell vinegar when you open the cans, which is one of the byproducts of the decomposition process of these films," Spriggs said. "We know that these films are on the brink of decomposing to the point where they'll become useless. The data that we're collecting now must be preserved in a digital form because no matter how well you treat the films, no matter how well you preserve or store them, they will decompose. They're made out of organic material, and organic material decomposes. So this is it. We got to this project just in time to save the data."

That's... incredible. Then it sounds like they used a DNN or something similar to analyze the rate of fireball expansion in the films to refine their earlier estimates of yield.

What a beautifully subtle use of tech.

I read through chapter 15 on the "back end" of the assembler. I was hoping to read about how the opcodes got turned into binary codes during code generation, however I didn't see any literature on that part of the topic.

How is that done in practice, is it just a giant lookup table for the particular ISA being targeted? Does anyone have a good resource for learning about this part of the back end?
> Gravitational acceleration doesn't exist (in GR).

A better way of stating this would be that objects moving solely under gravity have zero acceleration in GR, because in GR, acceleration means proper acceleration--what is measured by an accelerometer. Objects moving solely under gravity are in free fall.

> All bodies are stationary in GR and observe other things moving in reference to themselves.

This isn't correct. There is no requirement that an observer in GR must use coordinates in which they are at rest.

Yes and no. People seem to forget that CPUs are not magical and can have bugs. On top of that, each processor family and processor stepping[0] have their own distinct bugs. (An example list can be found at [1], starting on page 8.) Well known incidents include the Pentium FDIV bug[0] and the more recent TSX bug[1] but there are a whole host of lesser ones that never reach the public consciousness because the OS works around them, e.g [2]. Needless to say, creating these workarounds takes time and effort and re-testing and that translates to money. And anything that costs money, well, ...

1. There is a weird regionalism in the outer boroughs of New York City where the grocery stores don't hire someone to bag groceries. Either the cashier does it (which I think is totally normal) or there's someone who isn't paid by the store who bags groceries and collects tips in a little cup in the bagging area. I think it's so weird and it's the one place I've never tipped. I think I can count on one hand the number of times I've seen someone actually drop money into the jar in 10 years and the jars only ever seem to have pennies and other change in them.

- Compatibility: Guile 2.2.0 is among the 10 most complete r7rs Schemes, missing only circular lists (the other failed task succeeds when allowing a longer task time).

The encryption relies on you using (and trusting) the drive's built in encryption function.

Most SSDs with built in encryption don't directly encrypt the data with your password - they encrypt the data with a random password, then encrypt that random password with your password. They do this so you can change your password without having to re-encrypt all the data on the disk (which would be slow, and could cause data loss if there was a failure during the re-encrypt process).

Even when you haven't set a password set on your drive, most SSDs encrypt all the data on the actual flash chips (including reserved space, unused space and spare/reallocated sectors) and just store the random password is unencrypted on the same drive. By activating the on-drive encryption, the random password gets encrypted - making your data unrecoverable.

Of course, on-drive SSD encryption is all unauditable closed source stuff. And the cops have complained much more about iPhone encryption than SSD encryption. Make of that what you will.
Pregnant Women in America Die More Often Than in Iran
I had a dual boot since years, but I really switched to ubuntu only in 2009 (thanks to vista64 not supporting my scanner and printer). It is the main home computer that is also used by my wife. In order to make the switch as smooth as possible, we were already using openoffice and chrome on windows years before. On ubuntu, I have checked that photoshop was working correctly with wine. Sometimes, after an update, I had to configure the desktop to not highjack the alt key. This is the single issue I had with photoshop on linux (I am using an old release of photoshop).

I still did not achieve to migrate to gimp (steep learning curve).
The formula for an object at radius r in the field of a non-rotating gravitating mass M is:

sqrt(1 - 2M/r - v^2)

instead of

sqrt(1 - v^2)

(where I am using units where G = c = 1). For an object in a free-fall circular orbit, v^2 = M/r, so the above formula can be simplified to

sqrt(1 - 3M/r)

American Health Care Act: Last Week Tonight with John Oliver (HBO)
I largely agree. The only thing that will remain constant is that the news today is absolutely terrible since it's trying to become entertainment and not what it should be: news.
Sorry but I find that this blog has an error.

It says encrypting it and throwing the key away is going to make data unrecoverable.

While thats true for now, what happens when tech reaches the point that current encrypted items can be done within milliseconds?

So yes while encrypting it will make it so that the person that wants to extract information out of it can't do it with the current tech, but whenever a breakthrough on that field will happen then that person will be able to decrypt the SSD.
I do wonder why they actually go so far as to block the updates.
Yes, there's an optimization. Specifically, there's a trait called "NonZero"; if T implements it, then Option<T> uses all zeros to represent None, and so std::mem::size_of::<Option<T>>() == std::mem::size_of::<T>(); If not, then you have to store a tag.
Posting that opinion in this thread was bound to generate confusion, but I get your point. That's usually called divulgation or public awareness. The problem is that it's often quite hard to do, because most practitioners only understand the concepts in terms of that mathematical language, and it's quite hard to translate them, since you can't easily put yourself in the shoes of someone who doesn't understand that language.

Also, it's not clear that there's any point in doing so; say you can explain a very technical concept to a layman using terms and concepts that don't require two years of study. Then what? What is that person supposed to do with that knowledge, if they lack the mental tools to apply it? It becomes little more than trivia, no?

Still, there are some attempts: http://math.stackexchange.com/questions/275/best-maths-books...

>They're touting the use of adult stem cells which have never been shown to provide the kind of results that embryonic stem cells have

Actually that is false. As someone who is currently losing their eyesight due to retinal degeneration (and in their 20's no less), I've done quite a bit of reading on this subject. Most of the stem cell treatments and gene therapy that I've seen rely on the patient's own cell cultures in order to prevent autoimmune rejection. Normally the retina has immune privilege, but as it breaks down it becomes vulnerable to attack by the immune system, which adds an extra level of complication.

Honestly, this whole thread has me pretty worried that I might be cut off from access to experimental treatments just because they're not guaranteed. I know you all mean well, but going blind with your whole life ahead of you and no treatment whatsoever is a really scary thing. These women made a fair trade, and honestly I would accept the same risks that they did. Having a chance at not being blind is better than for sure going blind.
Maybe instead of trying to write specific regulations for every little thing, we should just equalize this imbalance of damage.

If a seller's misbehavior causes a buyer's death, then consider that as murder. If it's premeditated, execute the people responsible.

OK, I don't really think this would be a good idea, but I do think it's worth at least thinking about how that would look and why we don't do it. Why is it that the alternative to regulation must always be "caveat emptor"? If a company deliberately sells a faulty product that kills a customer, they should be treated just like a common criminal who breaks into someone's house and shoots them. From this perspective, regulations are as much about protecting the sellers as it is about protecting the buyers.
I feel like 200 years from now, our times will be viewed as something akin to the industrial revolution. Recency bias makes us feel as if we're more important in history, but 200 years is a long time. I'm sure there'll be another "revolution" or two in that time. And the people of that time will probably consider it to be the most pivotal revolution yet.

History folks. It repeats itself.
But then you have people who would complain because they don't want to pay for x at all. Still many people would not read it and remain ignorant.

Unless the hole is rotating extremely rapidly (which I don't see mentioned), the difference between the Kerr metric and the Schwarzschild metric (which is what I used for the formula I posted upthread) is too small to matter unless you are really close to the hole's horizon.

One big advantage is that this unified recursive representation of code allows structural editing. With things like Emacs's paredit you manipulate code structure directly by splitting, joining, and moving subexpressions instead of editing code as flat lines of characters.

Btw, of modern Lisp dialects, I do not like Clojure for undermining this advantage by not syntactically grouping everything that is grouped semantically (e.g. binding pairs in let) just to use less parentheses. In my opinion, Scheme syntax (Guile is a Scheme implementation) is much better.

Opus – Open source knowledge base application for Teams
I studied in the UK. I think our systems are rather different because a lot of that stuff is taught in secondary school, so you're expected to know it before starting uni.

Which is all well and good if you stay on at secondary school (or attend a sixth form college) until you're 18, then go straight on to uni. But that doesn't apply to everyone (some people leave school at 16, or take a break before going to uni). So I can imagine that a lot of CS graduates here in the UK would have studied these aspects of maths quite some time back (and therefore can't remember them very well) or not have studied them at all.
