I've seen this mentioned in past discussions, and this is definitely the way to do interviews.

Show the candidate a piece of code and let them review it, something they'll actually be doing frequently. You'll get an insight into their understanding of the code and how they communicate improvements.

For a follow-up/bonus round ask them to suggest changes and fix it. A candidate that does this unprompted and well is a positive signal in and of itself.

No stressful whiteboarding and trivia questions. Just a relaxed conversation with their peers that they'd regularly have during work.
Well... I don't think it is on the interviewee to do this (ie start a discussion).

A lot of interviewing advice tells candidates to only speak when they are spoken to and to only answer the questions they are given. It is also a cultural thing, in some cultures candidates will absolutely not volunteer any information on the interview. I can't really fault a candidate for doing that.

On the other hand I can create opportunities for discussion, especially when my interests or expertise and the interests or expertise of the candidate intersect.
Oh, well, that's worse than I thought, but I think it basically bolsters my argument: A subsidy for them could not even be checked off against their tax contributions to the state's economy.
im just curious how they knew the person of interest read that article?

Was he a person of interest in the lead up to the shootout, who got away, and they were just grasping at straws to discover a list of local area IPs correlated with known addresses he might have been hiding out at so they could obtain a search warrant?

If that's the case, then honestly I don't think this is any worse than when they force say Google or Facebook to provide such data to government.

I don't see why the USA Today should get any special privileges over any other tech company just because they are "media".

If we want to have an argument about the Government abusing it's power to spy on us in general, that's one thing. But the USA Today is literally saying its more important they protect the illusion of their readers "privacy" (which we all know they don't care about your privacy are willing to sell all your personal info to the highest bidder, its in all their TOS) than it is to try and help the cops catch a child predator...

I do agree that this does establish a troubling precedent, but i kinda thought Snowden already made it blatantly clear that the NSA and the CIA is already doing this.

It seems to me that the FBI is basically just trying to play catch up, which we should be concerned about because they are supposedly the agency put in place to police us. Those other agencies are supposedly only supposed to police the world.

(which i never understood why thats supposedly okay. Americans are the only people entitled to their privacy?)

$5 per kg for the electricity expenses is far from magical, but it should be low enough to make the extraction profitable.

I do not know the current price of lithium, because most previous information sources, like the metal exchanges, no longer make their data public.

Nevertheless, a few years ago lithium was around $66 per kg.

So $5 would be just about 7.5% of the price per kg, but there are a lot of other costs, like replacing from time to time the expensive LLTO ceramic membrane and the very expensive Pt-Ru coated cathode and also many other operational costs and the amortization of the investment.

For reversible batteries, the conversion of lithium phosphate to another lithium salt might be enough, but for applications that need metallic lithium, like primary batteries or Li-Al alloys, the lithium phosphate must be converted into lithium chloride or other suitable salt and the metallic lithium must be extracted by electrolysis, with additional, higher, costs for electric energy.

However, the method described is sound and there are also useful byproducts to ensure or increase the profit.

The method is not new, but the major achievement is finding a suitable material for the selective membrane, which passes lithium but blocks the much more abundant sodium & potassium.

Unlike many such announcements, this appears to have good chances to eventually be used for lithium extraction.
> Even in television broadcasting, they consider audio the most important element. You can got a few seconds without the picture as long as there's audio.

I don't know who 'they' are because that's unfortunately opposite to what I have been witnessing for 1 year. Utterly useless but always present pictures, and a terrible, janky sound has become the standard of remote interview/consulting on TVs. Also don't forget that the new generation of field reporters is the generation who grew up used to favour convenience over quality, so they don't see a problem delivering lives which are barely understandable and, even worse, recorded reports which absolutely should be subtitled (the combo facial mask + bad sound take + bad Internet sound transmission) but which aren't.

Even worse, even on the national radio (the French equivalent of the BBC) which is supposed to have top sound standards; they obviously started using Internet-based public solutions streaming and they didn't give a damn about the sound: very bad and unstable quality, a LOT of lag causing a catastrophic mess of interactions, unreliable (connections very frequently dropping). It's a blessing when they have to drop to phone as they had been doing for decades, at least you know what to expect and there is no lag. Apparently they didn't consider the pro solutions which have been in use for 10-15 years (even my local associative radio had one!), which gave good sound with no lag, and which are a perfect fit at least for regulars; no, they all went using the crappy public app of the month...

In similar vein I enjoyed 1994 Neal Stephenson “In the Kingdom of Mao Bell” article in the Wired about CT2 (DECT like cellphone technology) deployment in China/Shenzhen. Even had obligatory “Snow Crash’s Neal Stephenson Visits Shenzhen” magazine cover tag line.

Article text: https://www.wired.com/1994/02/mao-bell/

Full magazine scan: https://archive.org/details/eu_Wired-1994-02_OCR

“Even people who carry cellphones carry pagers, which confused me until I found out that most of the cellphones I was seeing aren’t really cellphones at all; they are CT2 phones, which are cheaper and operate over a much shorter range. On a CT2, you can call out but you can’t receive calls, so you have to carry a pager. To cover a metropolis with CT2, tens of thousands of base stations would be needed. Coverage in Shenzhen is still spotty. When you see half a dozen young men loitering on the front steps of a building shouting into their prawns, you know there must be a CT2 station inside.”

If you’re talking about the file system share, there are better tools for people with the skills to get it set up. The tech seems good, but the set up is hard. The limitation of local network is rough for getting people excited, you should set up a tiny relay to let people connect.

The documentation is a little unfocused, but the pitch is good. If we assume the pitch is the primary purpose, simplifying the user experience should be the top priority. There’s a bunch of tools that have tried to solve the “throw file at Mom” problem, but I haven’t seen one work without putting my files in someone else’s server.

I’m not sure how you differentiate this from Plex, WD myCloud, OneDrive, or Google Drive. That’s an important factor considering how easier some are and how powerful others are.

You built a desktop UI in the browser to share files? That’s a bit much for anyone to take a serious look at. It’s the same problem as documentation and this post: needs more focus.

If you’re enjoying making it, and it does useful things for you, have fun! But I don’t see it getting much feedback or traction due mostly to lack of focus, but solving some of the technical limitations would make it much more broadly applicable and would help as well.
Probably should have added "/s" in the comment. It has become a little bit of a JavaScript meme.

That is why I think it's important we suffix our beliefs with a degree of belief. There's a huge difference between

- "that won't work, 60 %" (which could mean a healthy debate is the quickest way to settle the issue);

- "that won't work, 80 %" (which probably makes a timeboxed attempt the best way to settle the issue); and

- "that won't work, 95 %" (which signals something really wonky is at play. If two intelligent people have such firm yet different opinions, it's possible at least one of them has completely misunderstood the problem in the first place, or there's some other unexpected gap in knowledge.)

Of course, for that to work, we have to calibrate everyone's sense of uncertainty and keep validating their opinions to make sure 70 % really means 70 %.
I don't exactly remember when it was, I guess around 2005 or before. In a timespan from about 6 months multiple undersee cables had been 'hit by a ship' (pre Snowden, everybody believed the story). One cable was pretty bad, so traffic to asia was almost complet broken for a few days.

Everything you described is still a shared secret. Hashing your password client side is just a way to create a random, shared password. Yes, an attacker has a much harder time getting to your password, but they don't need to if it's the hash that's the one the server knows and checks against.

Absolutely, if that's the extent of what you want out of it, you could achieve that and call it a day. But programming is also a field that's ever evolving. If you catch yourself thinking, “I've learned everything I ever need to learn”, then chances are that you'll find yourself left behind at some point in the future.

The number of jobs that benefit from mastery of the craft is essentially equal to the number of jobs.

I do not enjoy finding the work of a bunch of people that studied enough to get hired and no more.
I, of course, agree with you:)

I give this as advice because I don't really care if the candidate likes me or not. What I care about if he can control himself and behave befitting the occasion.

If you can't do that on an interview there is no way you can do that later during normal work.

And I have clear, strict no asshole policy. We come to work to solve problems which does not require insulting each other. There is going to be problems and there is not going to be any insults because we understand we all want the same thing even if we have different capabilities, approaches and value systems.

I understand this doesn't mean people don't want to insult each other. There are always going to be tensions and what not. But I want workplace to be safe space for everybody. There is already enough stress, no need for people to be additionally miserable by asshole coworkers who can't control themselves.
>> Learn at least a half dozen programming languages

I'm always surprised by how many people disagree with this; they're on the search for that one language they can use for every task. Or even worse, they think they've found it and their search is over, that's a tragic situation given how spoiled we are for great languages today.

Clojure (STM / refs, vars, atoms & agents), kdb/q (non-loopy array code), Rust (ownership), Go (async done better, although i also really like core.async in clojure too), Python (trio nursery), C++ (asan, msan, tsan).

Everything you say is true, and leads to the oft-repeated "why would I want to learn this complicated programming concept, when my job doesn't require it?". That is, it encourages the idea that employment is the yardstick.

The rub is that this all depends on what you find personally rewarding. If what leads to a rewarding life to you is having a good job, then absolutely, you probably don't need more than a certain amount of depth and knowledge on the subject.

But if depth and knowledge on the subject is what you find personally rewarding, then suddenly putting in all this work makes sense. For many, lifelong learning is what is most rewarding and brings most joy, which one might argue is the most important thing as long as you have a sufficient income.

If you do want to frame it in terms of achievement, it's also obvious that many prolific people in their fields were driven by a passion for what they do — the playful nature of Feynman, Shannon and others comes to mind.

Apart from the sophisticated communications technology that goes into achieving maximum throughput through these long distances, is the power supply of the cables.

These cables have an optical amplifier every 50-100km which are supplied by DC power supplied through the protective metal armor around the fibres. Now if you think about it, what is ground if you have a cable between continents? There is no such thing as global ground, so there can be potential differences between of thousands of Volts.

Another one, how do you repair a broke cable that lays at a depth of 500m? TLDR, you bring both ends to the surface and splice a 1km of new cable between them. There are some videos from subcom (former TE subcom) on YouTube.

The "graphene" probably does add some modest mechanical and perhaps thermal properties to the foam of the shoe. There are plenty of papers and I'd suggest that you search Google Scholar and Google Patents for 'graphene rubber composites'; you'll be overwhelmed with examples.

However when discussing "graphene" it's helpful to differentiate between different types of two dimensional carbon lattices based on size and mode of manufacture.[0] There are two broad categories when we're talking about manufacturing applications at present:

The graphene in those runners is probably an exfoliated graphene micro/nanoplatelets made form graphite microparticles (previously an in-demand commodity for Li-ion battery anodes). The process used, given the industrial scale required, is most likely a chemical oxidation/reduction process (kind of messy), electrochemical means, or intercalation. The end result is more like confetti or the bits of paper left over from the hole-punch. This isn't your high-quality, electronic grade graphene, however most of the mechanical, thermal, optical, and electrical properties of graphene remain, and this graphene confetti can be blended into composites for the sake of those mechanical properties or to provide thermal or electrical conductivity.

Any company can blend a bit of graphene into their rubber or plastic and have the product given that sciency sheen. But you really want that graphene to be firmly embedded, since there are potential safety issues _in vivo_ [1]; Health Canada issued a recall alert for graphene-containing face masks in April, due to the possible risk of inhalation. [2]

The electronic grade graphene is generally larger in those two dimensions and presenting fewer defects — a full sheet of paper compared to the confetti type. For early experimentalists, the best source was also through exfoliation, albeit using Scotch tape to peel layers off of a large (1 cm or more in lateral dimensions) single crystal of graphite. Nowadays, epitaxial growth (i.e. grow one crystal using a different crystal as the template) is preferred, as it can be mass-produced, even using roll-to-roll techniques. That graphene can also be more readily transferred from one substrate to another, which is necessary since you are going to want your sheet of graphene laying on an insulating surface, rather than the metal on which it was epitaxially grown.

There are several other flavours of "graphene" — nanoribbon, oxide, fluorinated, multilayer, ligated, crumpled, charged, patterned, etc... But the two most consequential categories to keep in mind are whether you are dealing with "confetti" or "sheets". The nanoplatelet confetti can get inside you if not thoroughly immobilised.

Again, this is plain hypocrisy.

I'm not a liberal, and i think transversal warfare/fight, while needed, are nothing but a distraction for the working class (caveat: if we indeed lost the class warfare as Warren Buffet suggested, transversal warfare is the only fight left. I don't believe so.)

But this "cancel culture" and all this "woke" are just liberals finally using the tools the far right used. They exploded the overton window, and look what this got us: feminicides are not classed as passion murders but as real homicides, with the prison sentence that come with it. Gay marriage. Oh, and new historical figures we did forgot (in France): Toussaint Louverture, and also the less forgotten Henri Grégoire was discussed at length this year in class, while before only history nerds (like me) were aware of this figurehead of the french revolution.

No, honestly, i disagree with this strategy, but it is working, as the far right showed us in the last decade. But if you're complaining, complain to the one that used this formula in politics first. Else this is just plain hypocrisy.
My guess is this will be somehow tied in to the release of Windows for ARM64 with full x86-64 emulation.

Not that I expect to see it, but I think the opposite would also be fascinating. A natural partner for WSL2 would be Windows shipping with a full Android runtime, with support for ARM Android (rather than Android x86) apps. Hell, they could even offer the Windows Store up as a delivery mechanism for Android apps.
That's a good point actually. I've had my fair share of complete overkill designs in the past myself. Once I learned the problems it creates years later in large codebases I actively try not to do that anymore though. And to fix the earlier mistakes. Which is also fun: it's not uncommon to fix issues and even implement new features, yet end up with a diff showing more lines deleted than added.

> while SSD (also usually) die abruptly without giving any warnings or leaving time for recovering files

I had SSDs dying gradually and HDDs dying abruptly too. I think this is just the difference between the controller hardware failing or the firmware encountering some unrecoverable condition vs. failure of the storage medium.

That said, there still is the difference that HDDs retain data much longer, flash cells leak charge over time. So for long-term storage HDDs are still a little better, but "long" here means many years, so you're still in the domain where you're risking age-related failure, redundancy will be required either way.
Peace and quiet is so that you, candidate, can focus on the answers. I personally don't care if your kids organize the party in the same room, but I care if it causes you, candidate, to not be able to fully focus on the interview and then me, the interviewer, to have trouble understanding whether your behavior was due to disturbance.

Interviewing is an expensive investment. I spend a lot of time doing the interview and I want to use what little time we have to the fullest extent.
