I like your choice of the word myopia, because I think you've accurately captured one of the central problems in hiring. Rather than finding ways to accurately assess whether a person can do the job, grow in their career to benefit the future needs of the team and company, we instead look to more or less trick them using technical games and puzzles that generally have nothing to do with the work they will be doing.

> I think it’s a symptom of the tech world wishing to be associated with generally progressive human values

I'm having trouble parsing this part of your statement, but let me say that I think it is more a function of the personality types that get into software development and technology more broadly. Many of us are INTJ types (self included and yes I know that Myers-Briggs is bunk to many of you), and many of us have what was formerly called Aspbergers. In short, there are particular personality types that go into these fields, and those personality types fixate on details. So it isn't surprising that's how many then interview and expect their fellow team members to exhibit similar traits. Without going too far off tangent, I think this is often why this field is seen as combative towards women and non-white people, IE: it has less to do with a deliberate desire to exclude and more to do with the quirks of the people who enter this field.
Concentric looks really great! It actually has decent variation
I think you are interpreting "go read" as in go learn these by rote. He's not saying go memorize the details of these Unix and TCP books. He's saying go read them and absorb their gestalt approaches to decomposing complex systems so you can think about your own problems that way.

To this list, I would also suggest compiler construction or database systems as different topics exhibiting the same thing.

A more basic challenge for a scientific programmer might be absorbing the mindset of tool building rather than problem solving. It's a different mental perspective to think of your code as a product for other developers rather than as a means to producing a data artifact.
California approves goal for 100% carbon-free electricity by 2045
As someone who has recently started learning rust i can safely say closure issues where the hardest and most confusing things to learn how to fight with the borrow checker. This is especially the case since futures are becoming popular and require closures to be useful (obviously.)

This post covers a lot of the things I had to recently learn the "hard" way. Thanks!
Just wanted to say thanks for taking the time to give feedback. Swinging through the jungles of a new ecosystem is always fun, and guideposts like this are quite helpful.
Thyratrons were the early form of SCR, the silicon controlled rectifier. These aren't SMPS's in the sense we think of them today but they do switch the input at a controlled rate to create a controlled output so the nomenclature can be used in this sense. The proper term is: Phase-fired controller: https://en.wikipedia.org/wiki/Phase-fired_controller

You can see the idea is to run a timer that is phase locked to the incoming mains frequency. Now you can control when the switches turn on during a half cycle. If you turn the switch on at the beginning of a half cycle, you have full power. If you turn the switch on midway through the cycle, you get half power and so on. So your command signal asks the controller for more and more of the complete wave cycle until you get the full RMS value of the line voltage plus the load current (minus the losses in the rectifiers of course). The resultant output is a chopped up EMI laden mess but it does the job quite nicely after some filtering.

They were also used in early motor drives to control the speed of a brushed DC motor from single or three phase AC source. I know some lathes from the 50's or 60's had thyratron motor drives in them.

At my work we have an Electron beam welder which uses an SCR controller for the high voltage power supply. It's interesting: the controller is directly fed 480V three phase. From there in comes in through a breaker, a contactor, and two current sensing transformers.Like so (dammit variable width fonts...):

A--~~--||--S--^^^^^^--/--SCR---\---)

B--~~--||-----^^^^^^--|-BRIDGE-| )Inductor

C--~~--||--S--^^^^^^--\----------/---)

Key: ~~ fuse, || contactor, S current sensor, ^^^^^^ transformer primary

The three phases then run to the power three supply transformers in series and then off to a three phase SCR bridge for a total of six SCR's. The output of the bridge has a huge 200 pound inductor across it. The idea is the bridge is phase fire controlled and the inductor is so high in value that the controller can slowly watch the current ramp when the SCR's are turned on and wait until the feedback from the power supply matches the command from the potentiometer and adjust the phase angle firing accordingly. It's creating a controlled short circuit using the series transformers as the load. It's a primitive solid state method of varying an AC voltage. Before the SCR system they used a motor generator with an op-amp PID loop watching the feedback and control pot who's output controlled a small phase fired SCR bridge that delivered a varying DC voltage to the generator field winding. You effectively had a motor generator who's output varied from 0-480V AC three phase. Today you'd have a small metal oil tank containing an entire SMPS which is smaller than the control cabinets for our old linear supplies.
No, they can't use their free Azure credits towards Azure DevOps.

Azure DevOps is free for teams of up to five users. It's also effectively free for open source use by teams of any size. Larger teams working on private projects would need to be on one of the paid tiers and can't use the free Azure credits to pay for that.

Fair enough, I think I mentally substituted "Model 3" for some reason. I wonder if these fobs were designed 20+ years ago when the US crypto export control situation was a bit goofier.
any consumer rights attorney will take debt collector abuse cases on contingency - 40% cut. Abuse is so rampant (at least it was after the last financial crisis) it literally is like playing whack-a-mole for $1k/pop for every violation. A collector that repeatedly called my place of employment after being told I couldn't accept calls there, and threatened jail time, was forced to pay me $10k to me for their violations (and 8k to my attorney) on my counterclaim in addition to having their suit against me thrown out -- this was a law office that purchased debts and blanket sued and strongarmed/scared people into paying via violations of the FDCPA.. it's worth it for them because 90% of people give in and don't know their rights. It's even more worth it for those individuals that do understand the law and their rights.

Just document all calls, save all letters, and get a good grasp of the Fair Debt Collection Practices Act and any state-level equivalent (Rosenthal in CA) -- in CA you get to shoot the violators with a double barrel for federal AND state violations.

Having the major credit card companies increase my APR to 30% in 2009 having never missed a payment on anything in my life, while being backstopped via TARP and having literal 0% Fed/interbank lending rates blew my top off and I decided giving them the finger was my individual right of protest and damn the consequences. Little did I know I was entering an exciting world of learning how to beat the bottom feeders at their own game. Never paid a dime, made about $20k suing for violations, and my credit score was above 700 within 4 years and after everything fell off (7 years) it's like it never happened. But I'll never forget it - was pretty damn exciting to be honest.
IMO it would be significantly more user-hostile to disallow users choosing whether to use PTT unless the benevolent server owner allows it.

I know people who consider voice-activation to be an accessibility feature, as otherwise it would be too difficult/distracting to be able to use VOIP.

A community should absolutely be able to disallow voice-activation, but disallowing it by default across the platform would be an issue.

Correct. We are targeted towards full service law firms and the clients that support them (i.e. big enterprises). No plans to do the same for individuals / SMBs (but I think that could be a good business opportunity for someone else!).
the best teacher(s) in a 'bad' school overlap with the worst teachers in a 'good' school. Keep in mind that there is a relationship between student and teacher and that clicking with one teacher isn't guaranteed or that after a year of growing up, you might click with a teacher you didn't get on well with the year previous.
My ex mother in law was a lazy, morbidly obese dependent of the state who received well over a million USD in care during the last 10 years of her life. Even when her moron of a husband cancelled their insurance policy she still managed to spend months in the critical ICU section of UC Irvine while they cut out a bread loaf-sized section of necrotic flesh and rebuilt her intestinal tract. They didn't, and couldn't, pay anything.

She received care, without insurance, for heart failure(including oxygen concentrator and tanks), a pulmonary embolism, and back pains(among other things which I can't fully recall and am actively trying to forget).

I'm not saying it happens to everyone, but it does happen.

I would also look into PE corporate transaction work. This is a growing market (PE deal volume is up), I’m assuming most offering memorandum, etc. are very boilerplate, and I’m also assuming the clients would appreciate the differentiated up-front pricing model. Likely to be repeat customers as they could do a few deals per year, and the community is tight-knit so WOM would work. Finally, you already probably know this but I am assuming there is some overlap between the VC investment community and the PE investment community so you probably already have accounts today that could be natural entry points / “customer zero” for the adjacency. Just my 2c. Love thinking about this stuff.
I tend to agree with your take. When I did use it, I used it as a visual clipboard. A shoebox of diffetent ideas.

But I stopped using it because i could not do a search without signing in, which felt like an undue nag.

I'm not sure about contributing, but you can definitely see classes forking repos in github. I'm sure some fraction of them try to get their changes in, even if it's not required.

perhaps if you make it clear that it's okay to Google, then you might get a different outcome. it's highly common for candidates to assume that in an interview, it's not allowed or highly penalized to do so.
If defaulting on a debt is fraud, then why do lenders charge a premium for credit risk?

They do it because, in most cases, it is not fraud - defaults are just a fact of business. Being a lender is not a ticket to free, zero-risk money.

Both parties in a lender/borrower transaction understand that there is a risk of default, as well as consequences for a default. In a secured loan, the borrower loses the secured item. In an unsecured loan, more of the risk falls to the lender (which is why unsecured loans have much higher interest rates.)
I'm not familiar with LilyPond. Is there no possible client-side generation?

For example VexFlow (http://www.vexflow.com/) or, even with music, abcjs (https://abcjs.net/). Both of those use their own language.

A cursory look at the lilypond docs makes it seem like the language is pretty simple and straightforward... although, the source code looks nuts. How hard do you think a JS parser/vm for it would be?

Edit: been looking at some large lily projects from mutopiaproject linked below. Oof. There's more there than the docs let on. Still, would be a very interesting project...
What makes you think so? If it has been mentioned here or in the linked blog I’ve missed that.

Still, if it should be so obvious to any casual observer that the paper doesn’t belong in that journal: how did that escape the journal’s founder and editor-in-chief? (Maybe Rivin was also impersonating Steinberger!)
Unfortunately I have no access to an iDevice for the remainder of the week as I'm traveling for work. If anyone can help debug this and perhaps even submit PRs, it would be greatly appreciated!
Total cakewalk. Impressive!
Yes, I'd guess the effect in the single-digit percentages, and being in the index didn't help GE not get dumped.

Interesting question about market inefficiencies. Again, while they're not zero, I'd guesstimate them to be in the minor percentages...

If Amazon suddenly adjusts their R&D spend to show the massive profit of which they're capable, or does a massive increase to go after a new market, I'd expect it to go up or down massively more than the index and drag the index along. In that respect, the index may play a dampening effect, as people invested in index funds just go along for the general index ride instead of jumping on/off the AMZN bandwagon.
We are post scarcity for food, clothing, and shelter. In our lifetimes, we could easily move education, entertainment, and some definition of basic medicine into a post-scarce realm.

Unfortunately, before any of that happens, security, police, and military will be going post-scarcity, while those in power are pretty selfish.
Nope. That's too far. I am too lazy to write out the equations, so we can use an app such as this http://www.walter-fendt.de/html5/phen/projectile_en.htm to find out that it falls 69.5 m from the base of the building.
They address that within the manifesto:

A Caveat:​ We ​did​ graduate from college, and we ​did​ benefit from having friends, taking
cool classes, and acquiring ideas through osmosis. It is easy for us to suggest skipping
college without actually having done so. Again, the takeaway from this section is not
that you should or should not skip college; rather​, ​don’t make that choice on autopilot.

It's a fantastic read.

Literally everyone.

Imagine the tax income down the line if every citizen that wanted a high-training-required career could get that career. Imagine the burden reduction on welfare.
Imagine you are in inside of a giant beach ball, walking on the surface. You will never find an edge, and it is meaningless to talk about such a thing. Yet the space is finite.
I would google for the answer too if the expectation was to find the right solution quickly. I have rarely had an interview where they gave me time to think through a problem. The wanted "the" answer quickly without much thinking.
Would rather waste bandwidth than CPU cycles in this case. Would take way too much CPU time to mux audio streams together server-side, and then recompress. (Means we have to buffer data for each sender, deal with silence, deal with retransmits and packet drops, have a jitter buffer, etc...). No way we'd be able to hit the # of clients we want per core with that overhead. Our SFU's are intentionally very dumb for this reason.

Also, muxing server side means we can't do things like per-peer volume and muting, without having to individually mux and re-encode for each user in the channel depending on who they have muted and the volumes they have set per peer (which would explode CPU complexity even further).

So, in this case, bandwidth is cheap, let's use (and waste) some, in an effort to simplify the SFU, and also, make it more CPU efficient. Default audio stream is 64kbps (or 8 KB/sec), per speaking user.
I'd rather slit my wrists than have to herd a raid team any more than I already have to by micromanaging their voice settings. PTT or mute.

> The leveraged loans are now being packaged into collateralized loan obligations and sold to investors. Sound familiar? And the CLO market has grown to match the size of the CDO market at its pre-crisis peak. Yet one major difference makes the CLOs of today less scary: The loans that comprise them are backed by collateral, and if one of the companies in the mix defaults, an investor can find recourse through the sale of that collateral. Pre-crisis CDOs built on mortgage-backed securities had no such backstops.

Wait, what's the difference here? Mortgages had collateral- the homes. That's the C in CDO. The problem was that when home prices fell, the collateral wasn't enough to cover the loan defaults. It seems like the same thing could happen for a structured product based on other types of debt if the collateral turns out to not be as valuable as we thought.

This is meta but does anybody know the name of any disciplines where human history is studied through the perspective of evolution theory?

This subject is a mite tricky to Google.
Am I correct to understand that the main exploit here is:

A) A server that makes HTTP requests.
B) It does so based on a white or blacklist
C) These white or blacklists are circumvented due to bad parsing
D) This can be used to call unintended services (and sometimes protocols).

I had an idea to build a generic Webhook service. My thought was that the actual machine that does the requests should be 100% isolated from our VPS and only have public network access. Would that largely stop this attack? Perhaps it should also have a rate limiter to prevent DDOS attacks.

Waiting for every url parser to be fixed seems impracticable. This to me is a great example of why the WHATWG url specification is so terrible. It's so much harder to implement than RFC 3986.

Things that aren't browsers should just implement RFC3986 and reject anything invalid.
I don't know, but Steinberger stepped down due to a medical crisis sometime during this drama (it's hard to fix timelines because Hill waited a long time to write this Quillette post).

I don't know exactly where I got the impression that Rivin was the person who got this paper fast-tracked, but I think probably somewhere on Joel Fish's Twitter timeline.

As I understand it: NYJM is an online-only journal that continually adds papers to each "volume", so it's not like a typical refereed journal where there's a cohort of submissions and a calendar during which the whole peer review committee downselects submissions. You couldn't, for instance, easily fast-track a Usenix paper into a conference proceedings without blowing up the program committee.

And, again: you can just look at NYJM and then at this paper and see immediately that it didn't go through peer review. It is unlikely any paper I've found in NYJM for several years back. There are practicing mathematicians on this thread saying the same thing; Tim Gowers also says as much in the blog post we're commenting on.
> Where other countries often enact piecemeal and uncoordinated reforms, Singapore tries to look at the system as a whole. It invests heavily in education research. All reforms are tested, with the outcomes diligently monitored, before being rolled out.

Not being in the education field myself, what do other countries currently do, that isn't an evidence-based test-and-then-roll-out approach?

Growing up in the U.S., my parents were told by teachers that 6th and 7th grade was too early to teach a child algebra, because <various studies> showed that children can't handle the abstraction. But my parents, being first generation immigrants, insisted that the counter example of all my cousins in China is clearly evidence to the contrary. But surely my teachers in the U.S. had to have gotten their information from somewhere...
The Absence of a Patient’s View of the Early North American AIDS Epidemic (2014)
Short answer: Yes.

Survival is a very low bar. Going bankrupt qualifies as surviving since being alive along with having faith in the future can be enough to rebound successfully. Plenty of millionaires exist now because they learnt from failure from bad luck or poor execution of a plan.

Whether we taxpayers will be able to bail out various institutions that should have failed dismally last time is another matter. According to the article, banks are better off now but that remains to be seen. Nothing like reality to expose a gap in planning or regulations. Multiple institutions have likely not learnt their lesson and are probably unbalanced or unstable right now.

The downturn is likely already happening in some sectors in some obscure way and what the flashpoint will be is anyone’s guess. Possibly student loans but that’s a slow burn safely covered by the government and people who can’t escape paying so it’s effectively already bailed out. Might be the unpaid pensions which are already hitting the budgets of multiple states. Petrodollar consequences may be a factor since it might cause moneyprinting to be less effective.

Interesting times ahead I’m sure.

Hi, thank you for your feedback ! You are right, it would be a nice feature to add generic products, it will be implemented soon. Concerning the grades, high proteins, for instance, would show a green dot while high fats would show a red dot. Can it be confusing or it is clear enough ? Thanks again !
