Continuously pointing directly at the target tends to result in the missile being unable to generate the needed turn rate at the conclusion of the intercept. If the missile has a large warhead, that might not matter so much, but air-to-air missiles tend to be small.

Keep in mind that shells like Bash do an implicit 'exec' in case the end of the script is detected, no traps are set, etc. etc. etc.

$ ssh floeper echo foo '&&' echo bar
foo
bar

Notice how this should have printed "foo && echo bar" if this was passed to execve() directly.

The emphasis on that sentence from the man page should be on login shell. SSH always spawns a shell, regardless of whether a command is provided or not. It's just that it's not a login shell if a command is given. Your shellrc file won't be run.
So at no point did anyone figure that she was experiencing pathological amounts of anxiety around learning to drive, and most likely other ordinary activities? That sounds to me like an issue mental healthcare professionals help address.
> One of the commonly noted aspects of the GDPR is that it attempts to exert extraterritorial jurisdiction on any entity processing the data of an EEA resident, even if the entity itself has no assets in the EEA or other relation to it.

First paragraph.. already plain wrong. The GDPR only applies, if the site is offering goods or services to relevant citizens. That's quite a fuzzy criterion, though. To remedy the fuzziness, support documents list various criteria like: offering payment in Euros, having representation within the EU, using an EU ccTLD, and so on.

If the mass changes from m0 to m1, the velocity has to change by a factor of m0/m1 to conserve momentum. But to conserve kinetic energy speed has to change by a factor of sqrt(m0/m1).

Something else has to be involved to reconcile these conflicting velocity constraints.
Yeah this is much better than the title article.

> You seem to be under a misconception of what HN is

Please don't make assumptions about my understanding of things.

Nothing in my comments has anything to do with what is or isn't on the front page, or what should be or shouldn't be on the front page.

I'm talking about how you editorialized the title of the article to take away it's meaning - it's very reason for existing - and the reason someone might want to click it and learn more.

The article itself isn't much about the actual northern town, it's about how climate change is changing it so much - surely the title needs to indicate that.
Things can't really "leave", well they can, but the best guess we have is that there is no particularly special place in the universe, everywhere is roughly the same. So if even if all the really speedy stuff from here "left" we'd see the speedy stuff arriving from other places.
That would mean we should see the events where anti-particle flies, absorbs (or emits, or does none of that) some energy and turns into normal particle. Unless the moment of big bang was totally unique time when such things happened.
Yes, the publishing of the details is what gets to me. Throughout the article they treat the case as solved and the man as the guilty party, which they would never do to a living person before a verdict. To thousands of NPR readers, this man is not only the prime suspect but also the guilty party, in spite of the fact that charges will never be filed and guilt or innocence will never be formally determined.
It also doesn't really work if you have to tackle a new problem.

I stopped studying maths well before university. I am not some kind of math super genius. But working on my own stuff, which did involve new problems, I was up the creek fairly quickly without a solid mathematical understanding of the techniques I was trying to use.

I don't think the bar is particularly high here. Solid understanding of stats, ESL...but I have seen people shotgunning models (I did this years ago too), and that isn't going to work very long.

Also, I don't really understand why you wouldn't study some of this stuff. Maths as taught in schools treats you like a meat calculator...that isn't fun. But if you are interested in ML, going through Stats, Linear Algebra...it is pretty interesting because there are so many clear connections with your work.
> by making a payment out of it

I fail to see the difference here. If I have your IBAN and you haven't universally disabled direct debit on your account I can also use it to pay for something, for example by ordering anything I want from Amazon.

> eg. with stripe

Funny that you should mention Stripe specifically. You can accept SEPA direct debit payments with Stripe: https://stripe.com/docs/sources/sepa-debit

It is possible that the compliance requirements around this are slightly higher than for accepting only Credit Cards, but looking at the documentation I don't see any indication of this. Further, credit/debit card payments are subject to SCA whereas direct debit is exempt from SCA if the mandate is given directly to the payee without involvement of their PSP.
Firefox udpate script based around:

/usr/bin/wget -nc --trust-server-names \
'https://download.mozilla.org/?product=firefox-latest-ssl&os=linux64&lang=en-US'

which retrieves the latest release. After downloading, it's unpacked to a new directory named after the firefox version, under opt:

FFFILE=`ls -tr ./firefox-*bz2 | tail -n 1`
NEWFFDIR="/opt/"`echo $FFFILE | perl -pe 's/.*firefox-([0-9\.]+[0-9]).*/ff-$1/'`

and then linked to a standard place (/opt/firefox)

/usr/bin/sudo /bin/ln -s $NEWFFDIR/firefox /opt/firefox-new
/usr/bin/sudo /bin/mv -T /opt/firefox-new /opt/firefox

/usr/bin/firefox is already a link to /opt/firefox/firefox.

Old /opt/ff-XYZ dirs are culled manually.

This is easier for me than manual update from the browser, or relying on the distro's firefox updates. It also allows me a backout option while I acclimatise to new Firefox "features."

It took me about 30-40 manual updates before I got around to writing the script :)
I manage about 6 hours on average. Sometimes 3-4, sometimes but not often, even 7. Been like that for as long as I can remember.

If there's an advantage to this, it's yet to manifest itself in a way that I can recognize. Plus, it's boring because days aren't 28 hours long despite my needs. I would totally opt to need 8 hours if that would help me retain health and good looks.

Focusing on something often drags me down to 3-4 hours for up to 15 days or so. It's exhausting though and I bounce back to my medium after a good 6.5-7 hour sleep.
I’ve watched companies maintain their non-scaling DBs all the way to the grave.

It’s a killer.

Much better than "Googlewhack" for sure.
There's off the shelf libraries to do this in nearly every language.

Wow that sounds very similar to the culture I was in juniors were left to flail and management was bitter at their lack of performance. No mentoring existed. I think largely because management there were extraordinary developers that didn't need a lot mentorship themselves, or maybe after a few decades had forgotten the amount of input they had.

The attitude at the company I'm at now is amazingly different. The owner is trying to step back so he sees his most valuable work to be mentoring and teaching. The result is a company that can't stop growing. Everyone is developing their skill set and taking on new responsibility's.

I think the previous companies management took on so much of the day to day work they had little time for themselves let alone training others. They're genuinely brilliant and harder working than anyone I've met but just didn't build people.

Ask HN: How did you learn to learn?
Well I've played hundreds of games of Risk, against many different people IRL and also a lot online.

IRL you'll see that people tend to be "nice", don't want to push you too far. And they're also willing to accept deals like "hey, you want to agree that neither of us ever crosses this border here?" rules, because there's a good chance that you'll play again together, so being trustworthy pays off.

Online, the game is played very differently, and it's all about maximizing the results of every single turn, and completely ignoring any metagame or personalities. You might as well be playing against bots.

I tend to do a bit better offline, because I'm a bit of a charmer and people want to make deals with me. But online, I feel like I can try many more strategies without worrying about people thinking I'm "mean" afterwards.

I'm not objecting to asking questions, I'm objecting to preferring the HN commentariat over at least engaging with the posted content. Asking questions after reading the article is fine - that's part of creating fruitful discussion.

But HN does have a problem in that no one believes reading the article is worth the effort, and everyone prefers to just read the comments. The end result of that is a negative feedback loop of insularity and incuriosity, more people only engaging with the subject (or what they believe the subject is based on their reading of the title) on a superficial level rather than real intellectual discussion.
> but building things "properly" because "we may need it later" is a great way to kill a project with complexity

Emphasis added because I feel like I addressed this in the paragraph immediately after the one you quoted:

> Plus, as me and others keep saying, Redis (and other proper queues) isn't a complex addition to your infra

I'm speaking out of experience and, as I already pointed out in another subthread, Postgres is far more complex than Redis. Consider the presence of "DB Admins/Specialists" and the lack of counterpart thereof for Redis and other queuing solutions.

Of course, if queues are not central to how your platform operates, you might be able to get away with Postgres. I still advise using Redis as a reasonable hedge against someone famous tweeting organically about your service because in this case, you don't want your DB to go down because some queue table had a surplus of transactions (or vice versa).

Not to mention, at an early stage, your tech decisions set precedents for the team. Maybe you have 10K users with a low qps but soon you are sending marketing emails to them and your system has periodic bursts of queue activity for all 10K users at once. When discussing this marketing "feature" rarely anyone thinks, "Hey we can't do that with our Postgres queue", rather "Yeah I saw functions in our codebase for queuing---this is doable". This is a small effort but a huge technical investment for later on.

Humans use positrons all the time though, it just turns out (anti)leptons have extremely low mass relative to their usefulness.
Hold up. The article shows a mass difference of 10^-38 for the matter/antimatter states. That’s not a few orders of magnitude off your number, that’s literally your exponent.
Absolutely. Even if they don't end up backstabbing you, at the very least they'll be like: "Oh, you already dealt with the threat? Well then I think I'll just reinforce this turn."
Most of my dreams are interesting, but grounded at least somewhat in my real life, with the typical bits of surrealism mixed in.

Recently, though, I've been having dreams that leave me waking up, reflecting on various things in my life, often to my detriment. Interestingly, in a recent dream, I found myself doing accurate math (nothing serious, very basic arithmetic, but I've never experienced that before)
Like dialup mixed with ragtime.
> The headline here should be about the first measurement of a mass asymmetry between matter and antimatter.

The mass difference is not between particle and antiparticle, but between the mass eigenstates, which are not antiparticles of eachother. It's also not the first Δm to be measured. In fact, it was the last remaining one.

A few years before the turn of the millennium, I took a year out before university, and spent some time travelling around the country (I'm from the UK) and working in exchange for board.

A lot of communes which had been established in the 1970s and 80s were still extant, and visiting was fascinating and an absolute blast. Few of them still remain, and those which do have distinctly toned down, moving from howling at the moon, orgone accumulators and three day sundances to straight ecological workshops. Bit of a shame, really.
It doesn't seem necessary for an article about moral decision making to contain anything about utility theory.

For example, what if the author prefers a deontological framework? Then they'll write about that, and it'll be perfectly valid.

In either case, it doesn't seem necessary to mention any particular framework by name in such an article. Because it's an article on the Internet aimed at a popular audience, not an undergraduate philosophy textbook.

None of them can explain anything besides what is already explained without them.

The Big Bang theory that is useful starts with matter at very high temperature and density, but otherwise not different from the matter that we know. That happens at some uncertain time interval after the beginning of Big Bang.

We may try to extrapolate towards time 0 and increasing temperatures and densities, but that reaches soon values of temperature and pressure high enough that we do not really know how matter behaves in those conditions and it does not matter anyway because it does not influence what happens later.

For the later evolution, it is enough to start the modeling of Big Bang from the moment when the temperature became low enough, e.g. of some tens of MeV, i.e. when matter was too hot for nuclei and atoms to exist, but cold enough so that it consisted of a plasma composed of protons, neutrons, electrons, positrons, photons and neutrinos, with only negligible quantities of heavier particles.

For the time 0 there is no theory that can predict anything quantitative.
Thanks for a very interesting perspective. Wish you and your family the best.
Yup.... for me it was Amazon. And I was in H-1B back then, so I just put it up with it for a while, until the economy improved. The company had such a weird culture. It was pretty stressful.

The most insidious thing they did was delay the green card application as much as they could, and just drag things out on purpose. Since I am Albanian/European, I could get it faster as my country is not on the per country cap that Indian and Chinese applicants are. They knew it, as they kept dragging out the first stages of the applications on everything. It was mental abuse.

By 2011, the economy was recovering, and I did switch, but I had to redo all the green card application stuff again.

Nice! I built something similar with automating a movie making process by pulling gifs from Giphy, convert them to mp4 with ffmpeg, stitch, add a sound track, opening sequence and credits and produce a movie, all with just a keyword. Check out my code here

The article uses the examples following:

1. Sports. Specifically, basketball, swimming, and gymnastics. Pretty much every community of any reasonable size has a community pool and a community basketball court. There are at least 6 basketball courts and 3 lap pools within a 10 minute drive of my house -- that I know of! -- and all get regular use. Gymnastics is also reasonably popular.

2. Logo design. I'd wager there are way more logo designers today than ever before. Also, this was not a compelling example IMO.

3. Cars. This one is more complicated, but it's really safety regulations that push homogeneity. First, I'll assert that sacrificing participation for fewer bodies splattered across the pavement is a good thing. And, second, again, that's probably a false choice -- I'd wager that there are a larger total number of people designing/making/modifying cars today than ever before. Maybe even a larger percentage of the population (thanks, youtube).

This works for other examples too. E.g., climbing will be added to the next Olympics. The Olympic versions of the sport are what I would call extremely refined, but climbing is more popular than ever.

When TONS of people do a thing, and the rewards for doing it well are reasonably good, that is when you get refinement.

We don’t know a ton about dark matter. Basically (and I’m simplifying a bit) you need CP violation (and more than is explained by the standard model) to account for the asymmetry. If your dark matter model of choice can generate CP asymmetry, then it could enter the discussion.
I would assume that most large fleets have background periodic tasks that perform basic self-checks (the fleets I know about certainly do).

Using "idle" cycles is not a great idea though:

- They may seem "free", but in fact you would end up using more power: CPU turns itself off during idle time, and you'd replace that with an intensive process. Power (and, as a consequence, cooling) is one of the main costs of a data center.

- Machines that are properly utilized (close to 100% CPU utilization) would get less coverage, and those are the ones that need it the most.

So it is better to allocate a certain percentage of your CPU budget to self checks, based on risk and sensitivity of the tests. And have some easy way to put a machine under stress testing if it is suspected of having rare memory or CPU errors.
I think it assumes you have more than 2 people playing, and the other people haven't read this article. Which...doesn't sound like a sound strategy to me.
