Ask HN: Is it the right time to get into data science?
My wife have been trying for the past year to land a job related to data science. So far, without any luck. She has a genuine interest in statistics, with two bachelor's and a master's degree. She has been taking online courses in data science and even some ML courses to broaden her scope, and improve her cv.

She is willing to accept a junior position, yet so far there are few job opportunities, and she usually end up rejected before an interview. It should be noted - further hindering her prospects - that she's an American in Denmark and have no professional experience in data science and its related fields (after graduating, she worked as a school teacher). The ongoing pandemic has not helped matters either.

But comments and stories linked on HN make me think that even under good circumstances, data science and its related fields are difficult fields for which to land a job these days, even with several years of experience.

Is she misplacing her energy and focus on data science? If she is misplacing her focus, what alternative fields should she (or someone else interested in statistics, considering data science) pursue instead? And if data science is the right avenue for her, what might she be doing wrong?
Yes, which is an interesting problem for Parallels and VMWare. I would imagine the key requirement for most of their Apple customers is to run Windows.

On the other hand it might be an opportunity to offer Windows in the cloud to Apple users.
The spoil is by polluting shared natural resources that we depend on for quality of life. Such as clean water, clean air an functional eco system that provides enough oxygen, stable earth temperature.
We had data to justify shutdowns on the basis of a possible (i.e. consistent with the data that we had) worst case scenario. Doing nothing while waiting for more data to narrow down is itself a risky choice.
I'm actually annoyed we still don't know the exact death rate of the virus.

I am not sure if it would be that unethical to call up volunteers that reflect the general population to establish the real death rate. (even less so if you reward them economically)

If it is orders of magnitude less deadly then that should have enormous policy implications.
> Everyone in a civilised society has the right to a fair trial without the presumption of guilt.

This is absurd. A "right to a fair trial" is the standard for criminal trials, which are associated with criminal punishments -particularly but not always- imprisonment and execution.
The right to a fair trial has never been a standard we as individuals are obliged to follow in other contexts; for example: it would be ridiculous to think "a trial" is needed before we decide whether we should continue doing business with a company that dismisses its employees for being gay or trans.

Similarly, there is a long history of consumer boycott movements to pressure both companies and nations into acting more ethically; from Apartheid South Africa, to confectionary and fruit companies, to oil companies, to which eggs we might choose to buy. In none of those circumstances is a "right to a fair trial" a relevant concern.

A better question might be: How unethical does a company have to be before the act of just working for them should be considered immoral enough to merit public rebuke and repudiation? I don't think there's a lot of companies that reach that threshold, but I'm adamant that some should: Blackwater is the most obvious choice here.
My e-bike, which was a little on the pricey side, cost me ~1000 USD new. 8000 USD is absurd, and over 1000 USD more than I originally paid for my current car (a 2010 VW). Hell, whenever they're on sale, VW UPs are pretty close to that price brand new.

There's nothing in this bike that makes it reasonable to price it like a small car.
Interesting, I had never heard about this before. Apparently it "only" dates back to the year 1699, and it was a commandment for the "Khalsa" Sikhs, which to my understanding is a subset of Sikhs. Wikipedia says that:

> In the United Kingdom, there have been tensions between the Khalsa Sikhs and the non-Khalsa Sikhs. Many Sikhs in Britain have insisted on their right of not conforming to the Khalsa norms while maintaining that they are truly Sikh. On the other hand, some of the Khalsa Sikhs think of the non-Khalsa Sikhs as having abandoned the Sikh faith altogether.

Anyway, for reference, the five K:s are: Kesh (uncut hair), Kangha (a wooden comb for the hair), Kara (an iron bracelet), Kachera (100% cotton tieable undergarment, not an elastic one) and Kirpan (an iron dagger large enough to defend oneself).
The problem is that cops in the US are shooting way too often. Less lethal weapons just give them more opportunities to shoot.

That's not true. All believable statistics I have seen show only very small number of deaths in age group 55 and lower.

Outrageous claims require outrageous proofs, you need to volunteer your sources if you want to convince anybody that 55 and younger are large share of deaths.

"From what I have heard" is not an outrageous proof on HN.

> will use spare green energy to compress air into a liquid and store it.

Is that really right? It's not just green energy sources that benefit from energy-storage. Fossil-fuel plants and nuclear plants prefer to run at a constant output, but demand varies depending on the time of day.

See the 'Duck curve' https://en.wikipedia.org/wiki/Duck_curve
> Pledge lessens the amount of syscalls available to a program after it has called pledge(), so the threats it means to protect against is if someone tries to trick "ls" into opening a socket and doing network calls for instance, if ls pledges that from this point onward it will only do disk reads via the fs and output via text console.

Does that improve security? By how much? What exploitation would it have prevented? At what cost? If you're not measuring the impact then it's pretty much voodoo security.

> Just as a guide telling you to "chmod 600 webserver.key" doesn't really state anymore that it tries to protect non-webserver access to the https key, because it is implied that removing random access to the key (or to non-useful syscalls in the case of pledge) means the threat was unexpected reads of the key by someone who shouldn't be allowed to do just that.

Then that guide is of little practical use. On a multi-user server that chmod makes sense. Inside a single-user container/VM, it's completely pointless. If the guide isn't telling you what the threat model is, you have no idea whether the mitigations you're applying are relevant or not.

> No assessments would be found to say "chmod'ing 600 removes 56% of the unexpected read attempts, Posix ACLs 9% more, apparmor another 14%, and correct SELinux tags will stop upto 96% of the keyfile reads by the wrong user". If my wildly invented numbers were right would anyone suggest only using SELinux and leave keyfiles at chmod 777?

Yes! Of course. Would you not?

> But 0600 would help you the day some junior admin turned off selinux on the webserver because random HOWTO said colorls works better with it off.

If you think that's a real danger then include it in your threat model. Maybe SELinux is harder to understand, or configure, or too many people have access to its settings. Maybe it's the opposite (I've seen junior admins chmodding everything to 777 many times, I've yet to see one turn SELinux off). Either way, you need to explain that so that people understand it, otherwise you're encouraging people to cargo cult their security practices.
Thank you for this project and for putting the spotlight on this pianist. I listened to 'the new me' and it is very interesting how she did that and yet somehow there is a bit of Bach shining through here and there.
Scott didn't take down his blog just because of his relationship with his patients. It's one of his core arguments, yes, but it's tied with modern cancel culture, where speaking your mind if it deviates from accepted norms and ideas can result in significant personal and professional consequences, even if your intent isn't to oppress, spread hate speech, promote racism, etc. and even if the ideas you express are valuable in some way. It's dangerous nowadays to toe the line of what's "acceptable", where what's acceptable is decided by what people happen to feel on any particular day and how something can be spun into something it's not. Any number of character assassinations we've seen (such as the attempt on Stallmann) show that there are risks to being visible if some people suddenly decide they don't like you. Which connects with his other concern, that he may become too much of a liability for the place he works if some group or other finds something he's said controversial and tries to punish him or his employers for it.
No, it's because the UAW union opposed plants in right-to-work states. Other manufacturers like Hyundai have done well with new plants throughout the South.
It depends on where you live of course. Some countries seem to have the spread of the virus well under control. Others don't.

I live in Netherland; at the height of the crisis here, Germany has to take some of our ICU cases. Now we regularly have days without any COVID-19 deaths at all, and number of cases is dropping rapidly while testing is finally increasing.

Cool. Technology like liquid air, compressed air, electrolysed hydrogen etc. has a very different use case to lithium ion batteries.

Batteries are good for short cycle times, if you need to balance your grid and even to some extent if you need to correct for diurnal patterns, you want batteries. The high capital cost is compensated for by the high round-trip efficiency.

For seasonal storage or even inter-year storage, batteries do not work. You spend a fortune on them and then cycle the system once a year or less.

The advantage of these other systems is you can decouple three elements:

The conversion in

The storage

The conversion out

and match the capacity of each to what you need. For long term storage of hydrogen for instance, you want relatively small electrolysers with fast response times so that you can use excess electricity during sunny windy periods, a massive geological storage that can hold a year+ of production, and modestly sized fuel cells to turn it back into electricity in the winter (in Europe anyway) with good heat recovery.

In the case of this technology, you can again size the charging, discharging, and storage separately. The scaling for tanks is much cheaper than batteries.

Flow batteries use a similar idea by separating out the charging/discharging membrane and the electrolyte tanks but I don't think anyone has gotten satisfactory performance from them yet.

You can't build a lithium ion battery where you specify the storage capacity separately from the charge and discharge rates with anything like that kind of freedom. You can adjust the battery chemistry of course but nothing like the same.
You will only get detectable antibodies if the virus activated the adaptive immune system. This could be the case if the infection was successfully and quickly controlled by the innate immune system.

It's not of course but for long term storage the capital costs of the storage are more important than the the round trip efficiency.
Yeah, I skipped on getting expensive Ultegra or extra light carbon frame, as I feel that don't really impact performance much. But I will definitely go for disk brakes next time. It's just smoother, and doesn't strain the hands as much when going down steep mountains. Even better performance as I with a disk brake bike dare to go faster because I know I can easily slow down before.

Oh come on, I suggested nothing of the sort and you know it. You're not assuming good faith.

My remark is only that if delivery is better for the environment than going shopping, then that is a sign of a badly planned city (in terms of climate impact). Well-optimized delivery will address a symptom but not the cause. The cause is cities built for cars.
The question is, would it be possible to use large scale liquid air storage to speed up removing CO2 from atmosphere?

I have no idea if removing CO2 is easier in liquid form but if it is feasible then ff we already had huge infrastructure to store energy that requires pumping astronomical amounts of air back and forth, it might make sense make sense to add a bit to it to remove CO2 while in liquid form.
I actually agree with Facebook on this one, domain owners should have legal personalities.

That said, it shouldn't necessarily include their email, phone and address. Just the legal owner name (company or person) would be sufficient.
> The NY criteria for recording a Covid death has been pretty much anybody who could have potentially been infected at their time of death.

This is a common "fact" asserted in these discussions, and it's never backed up with any evidence.
As much as I don't agree with the aggressive tone of the grand-parent post, I tend to find it less a problem outside the urban areas due to the bike roads in the "countryside" more available either in Belgium or the Netherlands. It is also the part of the countries when the need of a car is enhanced due the need to travel way longer distances to reach day-to-day facilities (supermarket, shops, etc.).

And yes, different countries, different prices, requirements etc. Comparison is fallacious but taking inspiration of something done in another part of the world and applying it with the constraints of your own environment is always useful.

The question of mobility is much centred around the mobility in urban areas of various sizes. I may project here because I used to live in urban areas most of my life.

Small countries can ban facebook from doing certain things. Ultimately, some sovereignty exists even in global commerce. If New Zealand made (eg) political advertising, targeted advertising, or such ilegal, Facebook would stop doing it in New Zealand.

That is treating the symptom, but it is not totally ineffective.

Treating the problem is dealing with the monopoly. The current state of antitrust laws, norms and regulatory pressure is entirely useless. It's entirely based around regulating 19th century monopolies, and tempered by 20th century failings.

Facebook, Amazon, & Google are not Bell. With the old infrastructure monopolies, regulators needed to break up the monopoly without losing the services & capital investments. They needed post-antitrust companies to still be viable.

Facebook doesn't have that problem. Facebook could disappear tomorrow and consumers would barely be inconvenienced. Social media is not in short supply and doesn't require much capital. Facebook didn't need to sink much capital into building it. Their competitors will not need much capital to replace it. All they need is for Facebook to move out of the way.

Antitrust action, at least in facebook's case, doesn't need to be precise. It just needs to be strong.

We have labor laws forbidding discrimination based on national origin, and yes, some corporations use H1-B and related visa systems as a loophole around those laws to discriminate based on national origin and more than likely the rest such as race, ethnicity, etc. In my time spent in tech-related fields I have certainly seen companies provide more favorable benefits and overall treatment to say, Ukrainian SysOps vs their counterparts from India or Bangladesh.

This is what happens when a tech industry matures! Before it's mature and lucrative only the dedicated are into it, once it has matured there are layers of skillfulness and somewhere at the bottom the totally unskilled trying to get something.

It can be complicated even when it's not ambiguous. Consider:

template<size_t N = sizeof(void*)> struct a;

template<> struct a<4> {
enum { b };
};

template<> struct a<8> {
template<int> struct b {};
};

enum { c, d };

int main() {
a<>::b<c>d;
}

This is not ambiguous, but the meaning of the line inside main() depends on the compiler and the target - it can be either a declaration:

a<>::b<c> d;

or an expression:

a<>::b < c > d;

depending on which b gets selected. This in turn affects future references to d etc.

For all we know, Crystal might accumulate binary code cruft much quicker than Go as the project grows.
