> Why should a lab with $200k/year to spend on postdoc salaries be unable to hire a single postdoc at $200k/year? Current guidelines stipulate the lab must instead hire 4 postdocs at $50k/year.

The article pretty much answers this. It's impossible to convince the program office that a postdoc is worth $200K/year - that's substantially more than the PI himself probably makes. In reality, the program office will majorly push back if you ask for 10k more than the going rate. You can swing $5k more for a postdoc with some years of postdoc experience, but not more than that.

Given the way the contractual relationship of postdocs are setup, it's actually hard to find mediocre postdocs that survive in the system. Mediocre postdocs would be fired soon enough and a bright fresh PhD from China or India would take their place who's willing to work at $50k/year. That bright Chinese or Indian postdoc cannot easily accept a better paying industry job due to the nature of work visas for those countries so will work as a postdoc for several years till they can finagle a green card.
There is nothing wrong with "The infantry screen the tanks from enemy infantry". Screening is just the act of keeping two things separated. It does not matter which side of the from they appear. Either way is correct. If you want to go the protection route, "The infantry protect the tanks from enemy infantry" is obviously intended over "The infantry protect the enemy infantry from the tanks".
It turns out you're not the first person to realize that this is an issue. If you'd actually read up on cryptocurrency wallets before commenting, you might have found there are multiple solutions for this out already, including one of the most popular Ethereum wallets called Argent, which let's you set limits.

Basically the fraud described is a twist on the classic "Musk giving away BTC" scam that's all over Youtube because Google is apparently unable to prevent it. You have to be fairly naive to fall for it in the first place. But ok, no victim-blaming. The way you can prevent it on smart contract platforms is simply holding the funds in a smart contract that allows users to set restrictions so that they couldn't take that expensive NFT even if the user mindlessly clicks on a fishing link, connects the wallet and approves the transaction without checking what it is. Same as having a withdrawal limit on your bank card. And you can also whitelist wallets, the contract then automatically blocks any transfers to untrusted wallets. If the user manually overrides this by getting his guardians to agree, there's no stopping them of course.

Ultimately you won't be able to protect everyone. A determined enough fool can also go to Western Union and mail money to the scammer. In the US they have those prepaid card scammers. Or they come to your home, telling you they're police and need to inspect your valuables. Yes, that's a real actual scam that exists in Europe.
That would fall under the "sheer bloody mindedness" the gp comment mentions. There is no fundamental reason. Even Zimbabwe or wherever still has some taxation power.

There is some pretty weird stuff that could happen with bitcoin, because there is a lot of compute that exists, but would not be deployed once the energy costs can't be recovered with mining. Presumably at some point you get into 50% attack territory (which doesn't really have an economic incentive), and then what happens?
Perhaps the next inception is the NFT-drainer-siphon-drainer that spoofs the collection and botnet sites to trick the scammers into relocating funds into the wrong place. At some point, fencing these worthless NFTs will be needed.

Hmm.. create a botnet to sell NFTs on Insta.

Commercial pilots flying international routes should be making way more than $100k/year.
I really appreciate this answer. This is DEFINITELY the kind of reply they were hoping for, and instead, I awkwardly skipped over the details that would make it clear I know what I am doing. This gives me a good perspective, thank you!
An anti tank missile is a "drone" (and has been touted as the end of the tank for the past 50 years or more). Has the much slower-moving propeller driven contraption changed anything significant here?
Thanks for explaining. To you, and peer commenters.

> My guess is people don't pay attention or think about it.

This is a well known fact in secure system design. Most people just click through dialogs. If you must get their attention you have to make the dialog huge and scary but then people will usually just turn back instead of reading. Scary dialogs make it seem like you should never say OK.
I get your point -- most people don't really know what stock options are or that they are different from shares -- but options grants and RSU grants are both grants.

Aircraft carriers don't have the large cannons of a dreadnought. An armored car that served as launchpad and command center for drones could be drastically lighter, faster, cheaper, and with simpler logistics.
TMI vented a very large amount of radioactive krypton. (Given its density, it would better be described as dumped to the river, where it spread out along the banks downstream, gassing riverfront neighborhoods.)

Fukushima's containment exploded in hydrogen detonations, and vented a great deal of radioisotopes. They are today flushing tritium to the ocean, which seems wasteful; we will want the 3He that decays to.
> Do you feel the same way about plumbers?
Obviously plumbers don't enforce the law, manage evidence, write legal documents or have legal authority over others. If you can't see the difference in power dynamics between a police officer or lawyer and a member of the public I cant help you.

You're making my point for me, of course police need all of the skills you have listed (except maybe 'how to project authority', whatever that means). All of these skills should be taught to them by other police, while they are learning the job.

They also must know the extent to which they are allowed to use their authority, the situations in which they can use lethal force, the appropriate evidentiary and legal processes for taking a case to court.
If they learn this on the job then they are risking making process mistakes, or falsely enforcing the law, or breaching rules of evidence, all on real members of the public.
They should be educated in all of these things and the limitations of their power BEFORE they have access to that power.

Education in Justice is not going be focused on contract law, and I reject the assertion that a beat cop doesn't need to know anything about securities fraud. You don't jump in at detective, most police are going to start working the streets and then move to different roles.
No, the same arguments do not apply. Lithium ion battery production is essentially a chemical industry. It cannot become cheaper than its input materials. Most of the cobalt produced goes to lithium ion batteries [1]. Eventually, the battery industry hits the ceiling of what extraction industries can supply and shortages are already on the horizon [2].

Nuclear power plants are mostly steel, concrete, and copper. They need to be manufactured to precise tolerances, but the cost of a nuclear plant isn't driven by the cost of concrete and steel as rae inputs. The nuclear industry accounts for a negligible share of steel, copper, and concrete consumption. The lion's share of the cost is in the design, approval, and construction of the plants. Unlike batteries, these are factors that benefit from building the same repeated design. A serial run of 40 heat exchangers is a lot cheaper than a one-off production of 3 or 4 heat exchangers. This is why nuclear plants were so much cheaper in the 1970s and 80s when the same designs were built repeatedly.

> Yup. The key point is, a weapon system becomes obsolete when something else does its job better, not when it becomes more vulnerable. When something valuable becomes more vulnerable, you protect it better. When it becomes less valuable because something else does the job better, then you get rid of it.

What does a vulnerable tank do that self-propelled artillery doesn't do better? Not being vulnerable to small arms is one of the key value propositions of the tank, in a modern anti-tank heavy environment* tanks are just expensive slow moving trucks w/ a big gun.

*as we are seeing in Ukraine.

Use GIFs and screenshots to explain complex UI interactions. But for gosh sake don't only do screenshots for code, making me copy from a screenshot into my editor. Always include copy-paste-able code snippets when there's code/configuration to share.
That's a problem, but it's one that exists already, in that a tank crew with a broken or jammed radio is pretty much useless.
Honestly not sure, all I've done since I can remember is work. I need some change of scenery that will inspire me to do something else. Right now where I live it is suburbia and boring.

It's not a binary spectrum between action game and walking simulator.

Tomb Raider had some sections that probably fit the walking simulator genre, but also areas of action and puzzle games.

Walking simulator is defined by moving and exploration. Interactions usually involve reading, or changing your environment (not in ways to unlock new areas, but perhaps to see new things). Playing one, you clearly note the vibe. There isn't much to do except move forward and see/experience new things, building out a plot and understanding of a narrative as you do so. You don't generally drive the plot through your actions, but instead learn about it.
I am honestly mind blown that a scam tool like this isn’t minified and uglified to obfuscate reverse engineering. The process also strips comments, which I imagine would’ve been a preference of the perpetrator.

I assume the example from the author [of the blog post] must’ve been a deployment by someone without much experience with the javascript ecosystem or extremely lazy. Pretending this assumption is correct, what does it tell us? Is it a reflection of the environment’s lack of regulation (even industry/market led, like PCI) and a deluge of unsophisticated (ignorant) users/consumers?
That would be an out-of-context quote.

I'd say that attempting to prohibit this tradition has a net negative impact on the integrity and functioning of society because the harm in question is very minor but the reaction to such an attempt will be major. I'm sure you are trying to twist this into "but then I could anesthetize and then circumcise you", however, in that case I'd retaliate so drastically that it would negatively impact the functioning of society much more than say 100 circumcisions, hypothetically speaking.
They already tried to implement it years ago, or at-least Michael O'Leary claims so.
Where do the private keys reside in this scenario?

> There is no mechanism for Republicans to limit Congress from "addressing" anything.

Except for Sen. McConnell (like when he limited Congress from addressing Merrick Garland's Supreme Court nomination, neglecting his and other Republican Senators' duty to "advise and consent" on the President's nominations), though, to be fair, he has been far more reasonable since dumping President Trump.

But, generally speaking, that is basically the playbook of Republicans in Congress. They've been a powerful and overrepresented minority for more than two decades, so they can't move forward with their own agenda, they instead stall all other agendas, and nothing gets done. Then they complain during elections that Democrats can't get anything done. It's gaslighting, pure and simple. Republicans gaslight not only the vast, vast majority of their own party, more than 99%, they also gaslight American voters and Democratic Senators and Representatives. They can't win by playing fair and honest, so they haven't bothered with that honorable tactic in, well, decades. Republicans are and have been holding the country hostage and have turned the US Senate into a ineffective legislative body and basically have made a farce of the Framers' intentions. They're anarchists, basically. Republicans and anarchists have more in common than what distinguishes them.
> Keep two water reservoirs for cleaning your brushes. One for warm colors and one for cool. (This prevents muddiness in your palette).

I used to do a cup of designated dirty water and a cup of clean water but I can't think on that level when I'm painting. I'm close enough to a sink that I just change it out as needed. Any cup near me when I'm painting is going to get all manner of brushes dunked in it. Yes, I've dunked a paint-loaded brush in my coffee before.

Only slightly less vital: knowing when not to let the layers on your paper dry before progressing. But yeah, that one first.
This reads like sales copy. It's freemium FOSS-washed crippleware with a radioactive license (AGPL). Hard pass.

I'll stick to FOSS solutions that don't require licenses to unlock closed-source components and can be patched by a community and/or yourself.

Edit: Previously, there are other commercialish OSS NoSQL solutions for large-scale apps that are less proprietary with better licenses like Couchbase (not Cassandra CQL).
They can't even add ARA2 when every other major DAW has had it for years. Something is deeply wrong with Ableton, either they have trash product managers, SWE, or the 20+ year old codebase is too fragile. For example, why can't I have more than 7 collection folders?
Here's the Fed's Project Hamilton experiment [1]:

> In our design users interact with a central transaction processor using digital wallets storing cryptographic keys. Funds are addressed to public keys and wallets create cryptographic signatures to authorize payments. The transaction processor, run by a trusted operator (such as the central bank), stores cryptographic hashes representing unspent central bank funds. Each hash commits to a public key and value. Wallets issue signed transactions which destroy the funds being spent and create an equivalent amount of new funds owned by the receiver. The transaction processor validates transactions and atomically and durably applies changes to the set of unspent funds. In this version of our work, there are no intermediaries, fees, or identities outside of public keys.

That doesn't sound like Venmo to me.

Disagree. Those combustion vehicles are sticking around longer. Getting 15+ years out of a combustion vehicle is a piece of cake. They also have to be replaced. There is not going to be any where enough production capacity to replace all of those for a while. The early EVs will have shorter lives for one reason or another so the used market for those will suck for at least a decade. There is also going to be grid issues which will either out right prevent electric vehicle adoption or slow it. Sure, you might get to the point where few new vehicles are combustion in say 10 years, but the used market will be quite a different story.

Don't get me wrong. I WANT an EV, but there isn't one out there I would buy. No way am I getting a 1st, 2nd, or 3rd year EV. I'm not going to be a beta tester. No way am I getting an EV with just touch screens. No way am I getting an EV which is a pain to maintain or repair.
Nothing weird about that per se, but good job if true!
It's the opposite. The moderation is good, is very needed, and helps keeps discussion quality/signal-to-noise high, making this a site worth visiting. The thoughtless flamewars you can find everywhere else on the web are what bore me, personally. The rules of conduct on this site aren't even a high bar, and no one is preventing anyone from being jerks if they want to merely by keeping it outside of this forum.
Note that none of these exotic storage systems have ever actually been deployed commercially. Yes, liquid nitrogen is used for things like cooling. But no one has deployed a grid-scale storage system using liquid nitrogen. Liquid hydrogen has been used in rocket launches, but has not been used for energy storage. These technologies are mature in applications besides energy storage. They are not at all mature in the context of energy storage. Grid-scale storage systems using these technologies remains the stuff of prototypes and white papers.

This commenter is also incorrect in the claim that there is not enough renewable capacity to charge up storage. California , Hawaii, and other energy markets often hit days of excess renewable production. Proponents of energy storage promised that companies would swoop in to store and resell this excess energy. But this has not materialized, because energy storage is not nearly so simple or cheap as this commenter claims it is.
> "Scar consumption" as a phrase assumes that consumption in the American style is a healthy activity to begin with, and this outcome is damaging or ugly.

Well, not really. The basic problem is that production has to equal consumption. And so there are three possibilities:

1. People consume all of their income
2. People work less
3. People work, but get paid less

In a fair economy, the third point won't happen. In a country that wants an internationally competitive economy, the second point can't happen. And so people have to consume 100% in order to work 100%; this choice maximizes tax revenue.
OP is paraphrasing a quote by Leon Trotsky which originally refers to politics.
Thanks for letting me know, and in such detail. Appreciate it.
There's one caveat. Say a profitable company pays $1M dividends. With the industry-average 3% yield, this puts market cap at 32M. Currently you can get 3% risk-free with government bonds, and this number will go further up as the interest rate rises. Say, it goes to 6%. Now, in order to be competitive with bonds, the profitable company will need to find a way to pay 2M in dividends, or its cap will drop to 16M (i.e. the shares you bought will lose half the value).
I know it's cool to throw acronyms around but MANPADS stands for MAN-Portable Air Defence Systems.

They're for shooting down aircraft. The Javelin and NLAW are not examples of MANPADS.
If a general system becomes good enough, you see it displace specialized systems.
In this case the Kafka paradigm can be replaced because there is such a performant NoSql DB.

It's kind of like how standalone cameras became less and less desirable as phone cameras got better. Standalone could do better quality - but this matters less once both options are really good. There is some 'good enough' point where you hit vastly diminishing returns & simplifying into just phones became worthwhile.

Databases (certainly Scylla) may be hitting a point where specializing, actively optimizing, etc. are less desirable than just reusing one good system.

> Oil and gas cannot be produced on the same scale for the same returns as in the past.

Oil and gas is dead. We're producing far more electricity from renewables that we use, and England is buying it because they are struggling for power.

Do you really think a sane English government is going to let the lights go out because they can't make a deal with an independent Scotland?
This gets discussed all the time. Unfortunately most of the responses are from people on the interviewing side of the table who simply don’t like doing LeetCode, which doesn’t really answer your question.

Rather than answer your question directly, I’ll try to add some perspective that might help shed some light on why companies do this. You might be 100% honest in how you represent yourself and 110% qualified for the job as they’ve described it to you. This would make the LeetCode feel unnecessary and frustrating, obviously! However, from the interviewer side of the table they can’t really know how honest you are or how accurately you’ve represented yourself. If the world was all 100% honest and candidates were 100% accurate at representing their skills, hiring would be a lot easier!

However, as an interviewer who has interviewed a lot of candidates, strange things happen at scale. Often times you’ll interview someone who is not great at selling themselves (imposter syndrome) who excels when given toy coding problems like LeetCode. Or you’ll get candidates who have no-name companies on their resume or otherwise unimpressive credentials who will surprise you with great performance when given the chance to do coding challenges. Or, unfortunately, some times you’ll get smooth talkers with impressive resumes who can’t actually do any of the work they claim to have done. Hiring them can be enormously expensive for the company, both in monetary terms and in the morale that gets destroyed when you hire someone who clearly can’t program like they claimed.

The downside is that some times you get people who can’t handle LeetCode, either due to stress or anxiety or rustiness who may be great candidates if they had long enough to ramp up. This is an unfortunate negative of the process, but as you can see many companies have decided that this scenario is a necessary tradeoff to get the benefits of coding challenges.

I know not everyone will agree with what I’ve shared, but all of these scenarios (both good and bad) really do play out over and over when you interview at scale. Not every company chooses LeetCode, though, so if you have a personal disagreement with the concept then you can always choose to interview at any number of other companies.
