I attended a no-name college and went to a top-tier university for my phd (think mit/stanford/cmu/berkeley). I also taught at a different top-tier university. Everything below is specific to CS.

I think that top-tier universities are different in the top 20% and bottom 20% of students. The top 20% because you won't find those types of people at no-name. The bottom 20% because they're at least not completely incompetent (unlike the bottom 20% at no-name).

Here's how I break it down:

Top 20% of students at top universities: They really are that good. Also, they are the ones who benefit most from the intense curriculum at top universities. So they start off really good and actually do get a force multiplier effect from the comparatively very rigorous course-work. Most of these students end up on rapid trajectories in industry or with NSF fellowships.

Average students at top universities: Most of these students would be in the top 10% of the class at a no-name college. Still quite good, but nothing special.

Bottom 20% of students at top tier universities: Really nothing special. Comparable to the average student at no-name. Contrast with the bottom 20% at no-name, many of whom couldn't fizzbuzz on their first attempt in our senior interview prep course.

So, top tier places are really characterized by their top 20% and bottom 20%. The top 20% really are quite amazing to work with. The bottom 20% are at least not incompetent.

One last note:

> Or maybe the best of these students go on to work at companies that pay 250k/yr and I just don't meet them.

Most of my students at top-tier had offers in the $150K - $250K range. So if your sample of top-tier university CS students is sampled exclusively from non-entry-level engineers who did not receive offers in the $250K range, you're almost certainly sampling from the bottom 20% of top-tier graduates.

I haven't tried Missive, but how are memory and battery usage? I've seen fast electron apps, so I know they exist. Programmers basically treat memory as if there's enough of it to not care about, but Laptops are still sold with 8GB of RAM and the upgrade markups on current devices are insane.
This makes no sense. The Right IS in power, they control the senate, the white house, and the majority of states. Yet 4chan is as alt-right and anti-left as ever (ESPECIALLY /k/ which you think would be in full favor of CHAZ)
The ARM2 had about 30000 transistors and was already capable of doing significant things. The questions then are:

* How would you build a transistor?

* How would you build thousands of transistors?

* How would you make them reliable?

* How would you power them?

* How would you implement memory?

Depending on what materials you have to hand, and your abilities to machine them, and your power sources, many alternatives present themselves. You could even consider analog computers.

I am a professional artist; drawing stuff from out of my head and making it look plausible, if not actually correct, is literally my day job.

I have spent multiple decades practicing to be able to do this. Everything that I can draw out of my head and make look plausible rests on top of a solid foundation of spending time looking at real-world examples of the thing, or photos of the thing, and working from them.

There is a huge hump that artists almost inevitably have to get over somewhere in the transition from "amateur" to "pro": amateurs almost inevitably convince themselves that they need to be able to draw anything with zero reference, and if they can't somehow magically do it they are a failure; pros will happily draw a lot of stuff with no reference, but the instant they realize they don't know what a thing looks like, they will put down their pencil and go find something to work from.

Part of being a pro artist used to be maintaining a "morgue" - you would be constantly on the lookout for photos of things you thought you'd have to draw someday, and you'd clip and file them. The advent of image search has made this less necessary, but I certainly still have a few shelves full of coffee table books full of really nice photos of distinctive stuff - I have an entire book that is nothing but photographs of staircases.

How does the human body work? How do all its muscles sheath the bones and organs, how do you break it down into basic shapes that you can quickly put on the canvas and then flesh out into a realistic drawing? Which parts should you exaggerate when you want to caricature a particular pose? Which parts should you not bother with more than a basic rendering of to best serve the needs of the drawing at hand? That alone is a body of knowledge that artists have to spend years cramming into their head before they can be a pro. We regularly circulate little tip sheets[1] that talk about the ways we have found to simplify these things.

How much of your day-to-day work as a programmer comes out of your head? How much of it is looking through documentation and searching Stack Overflow?

Crank down the brightness on your monitor a good bit (more than you think you should), switch to light mode and stay there for the day. The initial dark-light switch is super jarring, I find, but light mode proper is actually fine.

And it's far easier to tolerate an instance of dark mode in a lighter-themed environment than the reverse because the initial switch is so much more jarring than light->dark (which can also be jarring, but it's not as jarring)

They probably don't pose the question like this, though. I suspect you'd get different results if you asked a person, "Can you draw an accurate representation of a bicycle?" vs pestering them to draw a bicycle so you can make fun of them later. I know for myself, if someone handed me a sheet of paper and said draw a bike, I'd do it for fun, but it would not be correct.
Abstract:

In this study, we explore how top executives affect the well-being of multiple stakeholders and long-run organizational outcomes. In the context of the 2008 global financial crisis (GFC), we examine how CEO greed impacts firms’ stance toward corporate social responsibility (CSR) prior to the onset of the GFC and how this, in turn, shapes firms’ fate during and after the GFC. We argue that CEO greed will be negatively associated with CSR, because in their unbridled pursuit of personal wealth, greedy CEOs are more likely to exhibit myopic behaviors and neglect investment in CSR. We also adopt a person-pay interactionist logic to theorize that the willingness of greedy executives to invest in CSR will be especially sensitive to different types of pay instruments. Next, we build on recent findings from research on CSR that suggest that stakeholder engagement is a defining feature of resilient organizations. We expect that, due to low CSR investment, firms led by greedy CEOs will experience greater losses in the short run and will take longer time to recover from the 2008 GFC. For a sample of 301 CEOs of public U.S. organizations, we analyzed the stock prices and found general support for our hypotheses.
Async is useful for high IO where you may have a lot of down time between the requests. Are you pulling many requests from different servers with different response times, communicating with a db or pulling out large response bodies. Async is probably going to do better since each one of those synchronously represents potentially large idling periods where other requests could have gotten work done.

As to the article the comparisons are good but fails to mention resource constraints, like Gunicorn, forking 16 instances is going to be a lot heavier on memory so for a little more RPS you're probably spending a decent chunk of change more to run your work and I don't think that's worth it considering the Async model in python is pretty easy to grok these days and under this benchmark share a similar performance profile.

Now that said If I had to guess these numbers are fine for the average API but if you're doing something like high throughput web crawling or need to serve something on the order of 10's of thousands to hundred thousands RPS async will win out on speed and resource use and ultimately cost.

Plus at one point they were like "we could only get an 18% speed up with Vibora" haven't used them my self. But 18% performance increase at really any level of load is fantastic. Hand waving that off tells me the work loads for what is "realistic" don't take in to account real high RPS workloads like you might see at major tech companies.

Yes, but we’re going to be restricted to O(L) final accuracy no matter what, for gradient descent (we could choose second order optimizations, etc, but that’s an orthogonal point — we’re happy to get within an epsilon ball of the answer).
>I think it is ok to be a billionaire, if and only if you give back to the community commensurately

How is it even remotely your business how much money other people have given somebody? A billionare (assuming they didn't inherit it) has already given way more back to the community than the average person, because they brought into existance something that collectively brought billions of dollars of value to people.
I'd be curious to know how and whether the death rate has changed over time. We've learned a whole lot since the "first wave", including the fact that it doesn't seem to really be a respiratory illness at all, but some kind of autoimmune/blood illness. Have the resulting changes to treatment had a measurable impact on survivability yet?

Does anyone have a good summary of Starship and what the goal is? I still don't quite understand why they didn't just iterate on the Falcon design and what necessitates a "full stack" clean slate approach. Why do they need to develop new engine for instance? Like.. why couldn't they develop new engine and upgrade the Falcons with them? Once Starship is working consistently, will the Falcons become obsolete b/c Starships will become much more reusable?
Disagree. Sure rust has a notable syntax tax (not what it used to be) but that's the easy part! It's the concepts and mindset that are the biggest hurdle in Rust. Going to C++ first won't help you there. If you already know it, great but Rust is a different language and you'll spend a lot time trying to transfer C++isms over until you realize writing effective Rust is not like writing effective C++ and you go through a process of unlearning. In my view, learning C++ for the purpose of learning Rust is massive waste of time.
It was very much an attempted solution to a self-made problem. Default toolbar config in Office programs had become so overwhelming that on a 1024x800 standard-issue corporate monitor you could literally see only a paragraph of text in the content area.

The true solution to that was probably deeper than clustering toolbar items by context. The very concept of a toolbar probably needed to be challenged.
Reading through the source of Elle:

We assert that all keys have the same type, and that at most one integer type exists.

I feel like Jepsen/Elle is a great argument for Clojure, reading the source is actually kind of fun. Not what you'd expect for a project like this.

That might explain misapplication during a riot, but it does not explain cases where police appear to deliberately target peaceful protestors or single out individuals like the press. In those scenarios they are either incompetent, deliberately aiming to wound, or too angry to think clearly. None of those are a good explanation.

Microsoft's violations, while having to do with the browser market, were not exclusive to it.

MS had something around 97% market share with Windows alone. They used that position to release their free, and largely broken if you go by the standards, IE browser. By pushing that free browser, which cost them over a billion in marketing and development, they cut into the markets of the cross-platform browsers. This was their game plan. Web applications (even the rudimentary versions in the mid-90s) offered a chance for companies to leave Windows, to remove the need for dedicated applications on thick client-styled machines. The OS would be come irrelevant, and this is something MS feared.

But that wasn't the only product market that they did this with. They straight up bought competitors and either closed their product lines or sold them themselves. They threatened to penalize OEMs who sold non-Windows OSes by taking away their OEM license cost (much lower than the shelf price) for Windows, with the margins of that market that killed many alternate OS efforts. They just couldn't get into the market, why pay $50-200 for a new product when you already have Windows on your computer?

I'd say MOST non trivial application require SERIALIZABLE. Every time apps does `BEGIN; SELECT WHERE; INSERT/UPDATE; COMMIT` it needs `SERIALIZABLE`, becuase it is only level catching cases, where concurrent transaction adds rows so that SELECT WHERE changes it's result set and therefore subsequent INSERT/UPDDATE should be done with different values.
By stating this, you are claiming that this fly-by-night unknown is like Stanford and Harvard. Stanford and Harvard don't need accreditation because they are the standards, and have set those standards for (Harvard anyway) nearly 400 years.

When this college has been around and is known as one of the most prestigious colleges on the planet for 400 years, then we can talk about it not needing accreditation. Until then, you're being disingenuous at best by pretending they exist in the same conversation.

This isn't news this is an advertisement. Ionization of air has long been a thing that's known to kill viruses and bacteria. The problem that they totally gloss over is the production of ozone which is quite harmful to people.

It's like they are trying the "on a iPhone" gimmick to make you think this is new technology. Look around you'll find ionizers everywhere especially at shops because they reduce offensive smells in the air.

If you're looking for something in your house UV light filtration works just as well for killing viruses and bacteria, there's inexpensive home units already, and it doesn't produce ozone. The health problems from ozone aren't something you want to deal with.

You can be wrong about your perceptions, if you’ve read your Descartes.

Dark mode could be more aesthetically pleasing, and yet could also be less legible. I have personally experienced this. Dark mode is hard to read and find my place in compared to light mode. The white space helps me absorb the information and use it effectively. I say this while I still think dark mode looks better for many apps. I just choose light mode because of utility and usability.

> I got scared away by rust’s syntax.

I’m curious about what you find scary about Rust’s syntax. I always found it to be a fairly natural extension of the syntax from C and other ALGOL-derived languages.

Its semantics, on the other hand, took quite a while to wrap my head around. I am reasonably productive in Rust these days, and I still sometimes can’t predict whether or not the compiler will allow something.
Being a monopoly isn’t the issue. Abusing monopoly power is. Commentators often miss that both is required for antitrust action.

In what market does Amazon have a defacto monopoly in? Apple is another one often brought up for antitrust related to App Store policing.

In the late 90s, early 00s, Microsoft sold 90+% of desktop operating systems (their monopoly). That’s fine, great success! However, they used that monopoly to harm competitors: bundling a competing product with their earned monopoly (IE/Netscape), threatening vendors which attempted to also sell a competitor’s product (Sony/BeOS), locking in customers by extending common platforms and making them incompatible with competitor’s products (Java).

Had they not had a monopoly, those actions probably wouldn’t be considered abuse. It’s the combination that’s the problem.
Justifying everything becoming a web app to avoid app stores seems to me a lot like swallowing a spider to catch the fly.

I would not expect the rate of rapes, robberies, and violent acts to drop to zero unless the area is completely depopulated. However, I think it is safe to assume that there are fewer instances occurring now that the police are excluded from the area.
Different engines (Falcon is Kerosene, Starship is Methane), fully reusable (even the upper "orbital" stage), bigger and simpler (Elon said a while back that designing Falson Heavy (1 upper stage, 3x lower stage) was pretty much as difficult as designing a whole new rocket) and therefore better (in rockets, the bigger the rocket, the better - as the ratio between "framework" (computers, engines, metal exterior) and "fuel+payload" goes down so you can lift more).
I expect that someone with an assault weapon and what looks like a bullet proof vest is scary for quite a lot of people. And that's notable in the sense that is goes against the idea of "a peaceful event similar to a music festival" (paraphrasing).

But Elsevier's lawyers would presumably argue during negotiations that the option to have CC0 distribution of text meets this stipulation, whether in spirit or letter.

I would bet that MIT's choice to divorce from Els came from a combination of ideoligical, budget, and reputational concerns (e.g. the UC system divorced from them as well and MIT now stands in solidarity). So I don't think issue was likely to be decisive.

I think that if the price had been right, all parties would have found a way to argue that the stated terms had been met -- or to simply not address them.
