> Stealth technology on a satellite would probably thwart detection in space well enough.

I bet you could make a satellite look like a stray screw or fleck of paint with enough effort. Careful geometry and surface design can reduce the radar cross section to a tiny fraction; some ultrablack coating and judicious heat rejection could make it look effectively invisible to optical and IR. Power with an RTG to avoid glints and radar scatter from solar panels.

And I'm sort of geeking out thinking about how you could misdirect observers about the payload's path— release a very shiny dummy payload, and then release the real thing some time before or after. Or pull a Millennium Falcon gambit and release the actual payload from a disposed fairing or stage when no one's looking...
HN never gets tired of the interview debate. I've seen the exact same set of comments for years now.
If I were the feds, I'd declare a two-decade long tuition freeze, to let inflation eat away the current crazy costs and force universities to find alternative sources of funding.

In those 3 examples you’d still both file your taxes at the same address and be legally eligible to vote there too.

Seems easily distinguished from the case of independent adults who sleep in different homes every night and have separate addresses on all their tax forms, drivers’ license and voting registrations...
Exactly - calendar notifications are "more important" than my frequent Clubhouse pings and having them in a more visible place is very helpful.
Apparently there are lots of these kinds of things around the world. I never knew that.

There's one in the Helsinki area in Finland as well: https://en.wikipedia.org/wiki/Pajam%C3%A4ki_Solar_System_Sca...

The funny thing is that its most central parts (the Sun and the inner planets) are in the least central location, in a wooded area in the suburbs, close to an industrial zone. Many other similar models seem to have placed the planetary monuments in public buildings or plazas. Helsinki? Yeah, we'll place it in the middle of the woods next to a bunch of garages.

(The reason for the location of the Sun might actually be that, according to the Wikipedia article, the model was designed by an amateur astronomer who has had his own observatory in the area. The model of Sun is also on a hill, which is nice and might make it more visible from further away except that, you know, it's not actually emitting a ridiculous amount of light.)
Same answer. Bob's decided to take something told in confidence and risk my reputation sharing it. He's not only a bad friend but clearly a risk so the best move is to burn him back and as hard as possible. He's getting dragged in and if he argues Im going to turn it into a larger issue for him. If we're coworkers I'm going straight to HR and asking what to do because a fellow employee infected me and then tried to put the blame on me. Anything but total calculated aggression will justify Bobs behaviors.

So putting water on servers don't destroy them?
Don't make the appointment if you can't dedicate your attention. If the CEO is too busy, they shouldn't be a part of the interview.

If something comes up, find a new host or give the candidate a mid-session break.
Headset with mic, a neutral backdrop, a key light, a good camera, and a skincare routine have all paid for themselves 10x since this thing started, in my case.
Companies that want to hire new people haven't change. If you want a standard web app you can demand someone with experience in the framework of your choice and get it. If you want someone to write in your custom language - you know they have to learn it so you hire people who can learn.
Our current DC has generation and UPSes in different rooms, in isolated places from each other. Both are pretty far from the actual DC itself.
> Is Nim garbage collected? There is no simple answer to that.

Yes, Nim v1 is a garbage collected language. It also shipped with custom destructors support https://nim-lang.github.io/Nim/destructors.html.

Nim v2, which is hopefully two releases away, will ship with a memory management scheme called "orc" https://nim-lang.org/blog/2020/12/08/introducing-orc.html

However right now, it is recommended that all new code is written with the `--gc:orc` switch.
The ersatz straitjacket of wealth, power and privilege never seems so restrictive that the wealthy who complain about it ever give it all up for the freedom to go slum with the proletariat. That should tell you all you need to know.
Once you pass 3-4 years of experience, it is not difficult to get at least a recruiter interview and phone screen in the US for a standard software engineer role. And that's with YOU applying — people get messaged by recruiters on LinkedIn all the time.
The self regulation argument is ALWAYS bullshit. If a company loses business by self regulating then a competitor may come a long and eat their lunch. We shouldn’t expect it, and shouldn’t be disappointed when it doesn’t happen.

This is what the public (government) should be responsible for. That way regulation is uniform (at least one can hope) across the industry.

If you choose to run 100% of your workload on a single EC2 VM in us-east-chaos-monkey and put nothing in S3, only local mounted block storage that also disappears when you reboot your on-demand EC2, that is on you.
It seems like a fool's errand to me to stamp out 100% of bias. Any bar that requires subjective assessment creates an opening for bias, and not every job can be assessed entirely by a completely mechanical rubric.

This is what things like representation are for, as they attack the problem for a different angle.
>if we anticipate longer windows or are doing things that can impact performance we typically announce it on our blog and twitter!

As a customer is there any way to opt-into a more proactive notification of an anticipated delay, like an email? I understand such things are necessary sometimes, but "always pay attention to some blog or twitter for a rare occurrence" doesn't seem particularly busy-stressed-admin friendly :).
You don't have to go all-in, but a common wallet is very useful as a wash account for common expenses.

Having an account just for expenses, with no overdraft, that's usually at $0.00 balance is useful for other purposes too (ACH pull is dangerous! Especially when everyone who has ever looked at your check can do it)

I think there are many other factors that effect this, including the culture itself. I just don't think France has the same culture of entrepreneurship that the US does. Places like Germany or Taiwan are probably better examples.
The problem with water in the same place with high power equipment is that it instantly turns the room into a death trap for any personnel, now everything is potentially live.

Also, in the first part of a lithium battery fire, dropping water on them is quite explosive. It will eventually quench the fire but on the short run it will make it worse, filling the room with explosive hydrogen and poisonous lithium hydroxide. So when your water sprinklers engage over your UPS, you better be sure there's nobody around: https://www.youtube.com/watch?v=cTJh_bzI0QQ
I guess it depends on whether you think someone has a right to a reputation independently of how they behave. Thanks for your answer, it was very enlightening.
Usually the qualities that matter most cannot be quantified (un)fortunately... One way to combat this is to have the interviewing team consist of people with different backgrounds. For example, if you want to hire more women, it probably makes sense to have women involved as interviewers for all candidates. If you don't have the ability to do this, then I'm not sure what the solution is.

>Any advice from experienced interviewers for the next time around?

I'm not an expert, but during the interviews of my last couple roles I hammered home better how I thought my skills would be useful to the company, and used phrases at the end of conversations such as "if you hire me, you won't regret it." I've also stripped down my LinkedIn profile to simple words describing what I do rather than a book-style narrative I had before.

Previously, I guess I'd assumed my resume and talents spoke for themselves when I'm more comfortable with my strengths, like simplicity. With this comes the confidence to not give a damn if I don't get a role, which usually helps my anxiety.
Terraform is great, but I wish more cloud providers had Guix/Nix integration.
I don't care what other things the author does. I came for the recipes and that's all that matters.

It used to be pretty common to find independent sites that had all sorts of interesting information and if you dug further you'd find the author has very extremist political or religious views, which you mostly ignored. Now it's all gone or replaced with a fake politically-correct "personality" out of fear of offending anyone.
UBI is a path to government dependence for everybody. Making the government bigger and making everybody rely on it to survive is very likely to turn out worse than reducing the size of government and letting people keep their earned money.

We do not need a larger government!
if I were the feds, I would stop underwriting student loans and make any new loans dischargeable under bankruptcy. probably a good thing neither of us actually gets to decide.
If you're running an IT operation this big, you should have both fire detection units and oxygen replacing suppressants.

That should be mandatory. Otherwise, it'd be very hard to contain. Especially when all your servers have RAID controllers with Li-Ion batteries or supercapacitors or other extremely trigger-happy components.

Oh, and cooling systems. You're just kindling the fire with it at the beginning.

One of my most frustrating interview experiences was when the lead engineer constantly interrupted me in the middle of my answers, clearly looking to get an answer that confirmed his existing opinions, then stopped the interview because we were out of time. He didn’t let me finish answering a single question, then rejected me because my technical knowledge was “too shallow”. I’m glad I never had to work with the guy.

My genetic grandfather (long story) in West Virginia is living with 800$ a year. 200 goes to property taxes, 24 for the gas well, the rest is for oil, repairs/tools and his weekly meat (and grain for his beer) (living beside a small creek, between two small rivers help a lot with growing your own food).

His horses died twenty years ago but from what i understand, since two young ladies are now living with his community, they want to remake the barn and get some sheeps and maybe a new horse. I'm pretty sure that i can get to FU money in 5 years if i go live there, i'm just not really interested (and i will have to get a US citizenship so :/).
What a joke. I've received two offers from Google and the first took nearly 5 weeks from start (phone screen) to finish (offer), and the second well over two months. And both offers were seriously disappointing.

Quantifying it is hard for sure, but some sample questions I've used in the past:

1. (Curiosity) How do you keep up to date with tech? Then explore something recent they started playing with and how they found it.

2. (Ability to learn) Ask about past failures, what they thought went wrong and what they'd do next time. If that's a bit harsh, ask what they'd change about their last major project.

3. (Ability to listen) For me this is about how they work with others, so probe for areas of friction they've had, particularly with people outside their immediate team.

You can't discount bias, but you get a baseline over a few interviews and can go from there. It's worth pointing out that all of these are soft skills, and quantifying those is always hard. Sometimes you've just got to trust your gut. It also helps if you've spent time working in a customer focused job, because you tend to be better at spotting egregious personality flaws.
> if someone submits a resume on day one that is good should we hire them or wait a week for someone else to discover the position?

if some company gives me an offer on day one that is good should I accept it or wait a week for some other company to give me an offer?

It cuts both ways.

> In most cases people don't actually have two serious leads to a job at the same time.

That's common for me, as I usually do a bunch of interviews around the same time when I'm interested in knowing what else is out there.

Most of the time I'm not really paying attention to my LinkedIn unless I see something that immediately catches my attention, which is rare.

> but for most people there isn't a choice.

If there isn't a choice people will decide and reply quickly, you don't need an exploding offer in that case.

This is typically a FM200 system in the datacenter [1] which is a pressurized gas. There are also often water "dry-pipes" in place that can pressurize if the FM200 fails. Fire suppression codes vary by country.

I think the flex here is photographic quality images from a video camera. 6000 pixels across is a higher resolution than the top digital cameras from a few years ago. Combine that with an easy way to extract hundreds of frames which can be stacked and you have a relatively simple way to create these deep macro photos. Similar techniques (e.g. lucky imaging) have been used for years by astro-photographers even in the days of 320x240 webcams.

I have no proof, but as the climate has changed and mostly gotten warmer it seems like the summer heat takes longer and longer to dissipate from the ground and the water. We used to have snow at the end of November in PA. Now snow is only in January and February. It feels like winter is delayed a month because of our warmer summers. It also feels like spring is what keeps getting shorter. It warms slightly and then summer is full on again.

The Future of Data Science
A huge number of people are turning to data science particularly in North America. I see people from all branches of engineering taking few online courses and writing their titles as Data Scientist in LinkedIn. I even saw a TV advertisement chefs becoming data scientists!

Where does this trend go? Will there an over-supply of data scientists soon?

It’s getting worrisome.
That presentation is pretty interesting, including Google inventing their own "Switched Tank" DC-DC converters because the existing ones weren't efficient or reliable enough.

I think Duolingo is fine for reading comprehension and basic sentence-building skills, but I think there are many better apps for vocabulary learning, such as Anki, Memrise and Closemaster.

The problem with Duolingo is that it doesn't really implement spaced repetition if you go down the tree in sequence. If you do a lesson about, say, technology you'll end up being prompted for "file", "mouse", "website" etc... over and over again, then you'll move on and basically never meet these words until you decide to redo this lesson.

I've just ended my 1200+ days Duoling streak literally two days ago, so I won't pretend that I hate it, but I must say that finally reaching my objective of getting a fully gilded Russian tree was a relief. I was getting really annoyed at the owl and its idiosyncrasies towards the end.

We make medical devices. They are surprisingly complicated things, and many peoples' lives depend on them. There's also a lot of ways in which they might potentially fail, and these failures can manifest years after the product has been in the field.

When there's even the slightest hint of a potential safety issue, it quickly becomes the top priority for a whole bunch of people. Most issues turn out to be false alarms, but we can never assume that. Lots of other things get put on hold, including hiring.

If you're an unlucky candidate who happens to interview right before one of these shit storms, you might be ghosted for a couple of weeks at least. Obviously we can't share the reasons for the ghosting, as much as we'd like to. Even a polite response from HR like, "Sally really enjoyed talking to you but she's unexpectedly tied up in something" can be market-moving information if you find Sally's role on LinkedIn and tie it to recent news about the company.
Treat them as bluffs anyway.

Of course if you personally were on the job market and were actually desperate because your spouse said "maybe its time to be realistic" and the bills were piling up, then you don't have the luxury of playing this game.
So being a current homeowner, do I have a financial interest in preventing new houses from being built?

I remember, back around 2008, houses were popping up everywhere. You don't really see much of that anymore, at least in my experience. ALSO, lumber prices are HIGH and its not as profitable to build new houses, at the moment. But what if this is a larger lumber shortage/sustainability issue? What then?

Could it be a mix of material supply issues and interest groups that are maintaining a housing shortage?

Having been on both ends of the income spectrum over the years, I am convinced that curiosity/side-project questions are simple proxies for financial stability rather than anything deeper.

Why is this news? I had always thought the People's Republic of China and the Great Firewall were doing this. If they weren't at some point they would. Control hinges on controlling information -- or maybe it doesn't, either way, there's not going to be a revolution to overthrow the Party anytime soon. I figure citizens have just resigned to the idea that they're being watched and evaluated on a daily basis and just find a way to go on with their lives.

72 hours is quick. A week is more reasonable. I had one company try to pull a 48 hour decision on me and I straight up told them I was declining the offer if they didn't give me more time to consider it. They backed down.

This is a decision that will impact my career trajectory, and I may have other offers coming. So yes, I want enough time to consider all options before making a decision with ramifications that will last years.

IIUC but global warming is somewhat of a misnomer for local weather effects, which can include colder winters; i.e. global warming is thought to cause more extreme weather in general.
