Agency Confessions: Are small mistakes taking big bites out of your bottom line?
Some very valid points. As a PhD student I had similar considerations and on top of that my biggest reason was that I did not want to go into a painful postdoc career only to start on the arduous path of obtaining tenure.
That said, despite the limitations, academia is still by far the best place do research (on average). Especially as a professor, you really do enjoy freedoms that are rarely if ever found in other realms.
No, because charges for violating tax laws must originate from the tax authority, i.e., the IRS for federal taxes. Prosecutors don't have the authority to file charges for tax law violations on their own.
Yes, you are right but I think Ant scales better according to the my experiences.

That's actually true, and very obviously so. I'm sorry.

I agree that clear notation is important; the pictorial style made me think of Feynman diagrams. My comment was a bit tongue-in-cheek, maybe unnecessarily so, but the point is that I fail to see how those pictures are clearer than plain text: you are not replacing complex stuff with a simple representation, you are just rewriting a simple formula in a different style.

> Also there are issues with the lambda calculus notation...

Are there? That's the same problem you face whenever you have dummy variables, e.g. the 'dx' in integrals.

If your DEs are linear, you can use Laplace transforms to find an exact solution. This is much simpler than inexact numerical methods.
This seems like a very pointed view of a certain kind of government, not government as a concept. If the people are willing and willingly choose a government, it's most certainly possible to govern them as long as that government actually listens to the population, doesn't indulge in corruption and earns the respect of people, not demands it.

Whether this type of government will ever come about in our modern world... Let's not get depressing.

These engines generally don’t use the DOM; instead, they render in a canvas element and provide you a framework to deliver logic and drawing instructions to each frame before it renders. That’s an entirely web-standards-compliant approach as Canvas was meant for this. There is stock code and art out there to save you time creating in-game objects for any particular engine (my personal preference is Phaser. )
I completely agree with this. I have a constant battle with some (not all) of my team to get them to think through a problem from its fundamentals, and try to find the best one or two or three ways to pose the problem.

Conveniently-posed problems lead to both convenient solutions, as well as a variety of potential ancillary benefits.

One practical application of this, for those who are more business-minded, is that I have set a very clear and tight tech strategy for our team. There have been quite a few instances where posing a problem differently has allowed us to better align with that strategy by enabling us to pursue solutions that make use of our existing technology stack and in-house tooling, rather than requiring us to introduce more dependencies and spread ourselves even thinner.
I knew a guy in high school (1997) who was talking about this thing called Linux. It was a super complex operating system and didn't even have a graphical interface. Our thinking was if we managed to install it we'd be geniuses or something. After a few days we got it installed on his PC, but i'd yet to install it myself.

Unfortuantly the only computer I had (not counting the family PC) was a laptop with 4MB of RAM (effectively less than 4). The installation required booting one floppy disk containing the kernel, then swapping and loading another disk containing the installer. And course the machine ran out of memory during this process. I spent days learning how to compile a custom kernel that excluded the things I didn't need, until it was small enough to fit in memory and succesfully install it.

I think that's when I got hooked.

This topic really hits home for me. I went to a 'magnet' middle school on the other side of the river from TJ. I don't know that a more nerdy group of 300 students existed anywhere - or that any other group of people aged 11-14 had such a high portion of having submitted patches to open source software. It was, frankly, the only place in the world where I was ever told it was ok to be nerdy, where geeky obsession with learning about technology was praised rather than mocked. The anecdotes are amazing in themselves - I taught myself the difference between assembly and BASIC so I could write faster games on my TI83; the 8th graders built a mesh network in 2005; most of us had websites written in php or perl; we wrote guides on reverse engineering instant messenger protocols.

It was truly a phenomenal place and the forcing of these brilliant and motivated students back into an environment where they will be mocked for their intellectual interests is a great loss.
My Anecdotal experience is the inverse. Students and even professors struggling to solve problems analytically that are trivial to simulate.
According to many sources, sub-second is considered to be ultra low latency. 500ms is good for now but 250ms would be great.
I’m not sure where you are, but I can’t imagine anywhere where sidewalks don’t make sense. Upkeep is orders of magnitudes cheaper than maintaining a street, and provides incentives for people to leave their cars behind, especially for shorter trips, further reducing wear and tear on roads.

Keeping roads in shape for multi-ton vehicles to barrel down them is expensive. Keeping them in shape for humans, not so much.
It is a synonym for “in-place”, though. If academic writing was optimizing for reach, the more commonplace word instead of the latin variant would likely be used. To your point, though, if someone submitted a paper using “in-place” someone would probably point it out [0].

I think that’s the original point, that a lot of the word-level complexity is just how the writing is taught and subsequent reinforcement by mentors and peers to use the appropriate language.

Yeah, elucidate is just a fancy word for “figure out” - but I think it is part of the dialect because of the connotation you mention (Even if a casual reader might not use it).

[0] Not because it is strictly wrong, but because it violates how the in-group expects converse. I think this holds even if we go outside of phrases (One could argue in-situ hybridization is one item), as if I discover something new I’ll likely use the term “in-situ” if it involves similar locality properties
Both of those examples are just local idiomatic usages, there's nothing incorrect about them. You get those wherever English is spoken, including variations within countries and cities.

When I was 12 or so, I was fascinated by a video [0] visualizing the memory architecture of the Nintendo Entertainment System. I started researching the technical details of the console in order to try to make sense of what I was watching, and within a few hours I had decided to try to write a NES emulator.

Now, the NES emulation scene is extremely mature, and so I quickly came across a number of warnings essentially saying "the world has too may NES emulators, please don't write another one." I decided to go ahead anyway, and after spending about 2 years' worth of afternoons and weekends, the result was just another bad emulator. It was slow, buggy, incomplete, and the code was a mess.

By your standards, I wasted 2 years of my life making "yet another toy" emulator instead of "using [my] capabilities for a more useful goal." But I had a ton of fun, and the learning experience was absolutely invaluable. I learned in depth how a computer actually works at the hardware level (even though the NES is much simpler than a modern computer, the concepts and skills transferred over very quickly).

As a result, my practical programming knowledge today is vastly improved over where it would have been had I not "wasted" all those afternoons. Many of the career opportunities available to me so far have been directly attributable to the skills I gained working on that emulator.

In the humanities, it's even worse. Academia is stuck in this negative equilibrium, and even though many individuals recognize this, few or no institutions have managed to get out of it. Tenure and publish-or-perish are both big problems. Publish-or-perish also wasn't the norm in most schools until relatively recently; today, so many schools want to be "research" schools, even when they have relatively little business doing so.

The idea that cities must rebuild their infrastructure every generation is completely absurd.
Google "Big Mac Index" for an example.

TLDR: inflation doubles prices in 18 years. So it is math.pow(2.0, 1.0/18.0) - 1 = 3.8% per year between 1986 and 2004.

4.15% between 2004 and 2013 and has been rising further. Let's assume it's 4.3% to 4.5% now ...

Even though there are buggy WPA2 implementations, in general it's pretty difficult to get in unless a trivial passphrase is used in WPA2-Personal. With WPA2-Enterprise, it depends on the method used, but breaking properly implemented EAP-TLS is really difficult. Your best bet is to look for bugs in routers etc.

But this basically proves my point: if the attacker can get into your network, messing with the output from Paul Graham's HTTP server should be the least of your worries.
Consider Hsue-Shen Tsien, father of Chinese rocketry. He returned to China in 1955, when it was a developing country. Talent can be built up, it depends on the environment.

There's obvious educational value in having students build tools like compilers and operating systems.

Will this make Drake Equation[1] more precise? In particular its Fl parameter:

We've got recently pretty good and reliable estimations of these:

R∗ = the average rate of star formation in our galaxy

Fp = the fraction of those stars that have planets

Ne = the average number of planets that can potentially support life per star that has planets

Fl = the fraction of planets that could support life that actually develop life at some point

I'm not comparing Kubernetes vs rolling the same functionality yourself.

I'm comparing it vs onboarding to the stack of Load Balancers/virtual networks/container registration/service discovery/etc offered by the major cloud providers natively on their platform, which are going to be much more well defined for solving real problems rather than K8s generic platform.
> But, that would have left most of the codebase history showing that the last commit touching a line was "MARK REFORMATTED ALL THE THINGS".

Indeed, this is a good reason to do as you chose. I hadn't thought of it (even though I have done the same to a code base).
actually the opposite is likely to happen, as Scott posits.
My parents really wanted me to go to TJ; I lived in the county next door, took the test, and was awarded one of the first four berths to go to TJ from my county (I think it was the first out-of-county program for TJ). I chose to stay where I was and continue going to the magnet school I was going to, which was a creative arts/freedom oriented school, but plenty of the students like myself went on to get degrees in the hard sciences.

For reference, my school also switched to a lottery system the year after I was there (so I guess it was 20 years "ahead" of TJ; incidentally it was also one of the first public "charter" schools in the strict sense of the word, a school with an educational charter).

It's easy to say that things are only getting worse, I feel that way about my college, and so have alumni of that school for at least a hundred years. In the case of my high school, I think other more secular things have changed the character of the school far more than switching over to the lottery system (for example mass paranoia over child abductions, and school shootings).
The author suggests that because affirmative action was deemed a poor solution to the "problem" that too many Asian kids attended the school, the only choice left was to abandon the entrance exam.
Maybe the racist "problem" wasn't actually one and so racist solutions wouldn't be appropriate.
Non-native English speaker here, to me “maintain cleanliness” just feels a bit formal compared to “keep clean”, but doesn’t feel incorrect at all. It makes me wonder how many phrases the I speak/write feel incorrect to native English speakers.
You can't build the next wheel without first getting a handle on how & why the existing wheels were built the way they were. Even CS undergrads start with toy operating systems that they fill in the parts for (adding a filesystem, writing a compiler for a toy language, etc). There's simply no better way to learn.

> These students are obviously smarter than the average student, and therefore I would expect more of them, like inventing new OS concepts instead of mimicking age-old designs.

You can disagree but here are the facts:

1. The students completed the task.

2. The professor had intentionally built slack into the schedule to let ambitious students take this further to play around with the tools & their knowledge to try doing creative things.

3. The students used this to recruit others students to form a larger team around a more ambitious end goal

4. Self-organized to distribute work & build a schedule that minimized interdependencies

5. Completed their goal.

Aside from the technical stuff, these all sound like valuable soft skills that were learned/applied in addition to the technical achievement. I'd say both the professor & students did a good job here.

What's hard for me to say is what year this is. In my old engineering school there was a final project in years 3 & 4. Your team would pick some kind of vague final project (with consultation from your teacher), you'd get a budget for materials + connections to companies/vendors for sponsorship, & then go about building your concept. That's a bit more complex than this but also lasts 1.5 years and happens largely outside of school. This blog post is about a project done within the context of 1 subject AFAICT. That makes it way more impressive.

Students at this level simply don't yet (at least generally) have the experience nor a good understanding of the space to understand what are more significant problems to go tackle. From what I've seen you usually start that journey as a masters/PhD student.
The moment after two RNA molecules that copy other RNA molecules encounter one another, the seas are absolutely teeming with them. On the way, any other molecules that make it go faster, or stabilize the result, also get reproduced like crazy.

Nowhere in nature does any cell create a membrane de novo. So far as has been discovered, membranes are always produced by extending an existing membrane. So, arguably, life is that aboriginal membrane extending itself, and picking up helpful molecules on the way.

Young earth creationism, while it exists, is probably rarer than people think. Notably, it is not orthodoxy in the most widespread forms of either Christianity, Islam or Judaism. It’s probably about as common a belief as the flat earth thing.

Yes, we are RNA organisms that have been incorporated into larger organisms, just as we are prokaryotes that have been incorporated into eukaryotes through endosymbiosis.

I would have thought that the max SPI speed on the Pi is probably faster than your peripherals can deal with. Your bigger problem is system interrupts which might cause discontinuous capture. The speed is derived from the core clock which can go to well over 100MHz.

Control of the bus is probably handled by kernel drivers anyway, so you're not doing much overhead with Python.

Also make sure you use hardware video encoding. I don't know if the picamera library does, but worth checking. I normally use OpenCV with the omxh264 encoder. You could also run a gstreamer pipeline in parallel with your air code.

Edit: looking at you pipeline you use the lsm303 which is I2C not SPI? So that's 400khz max. And the Bosch BMP something which isn't designed for rapid measurements - even if it's over SPI they output of the chip will be your limit there.

Interesting you mention that.

I'm aware that the most common color vision deficiency is a weak red/green vision and not completely absent one. However, it's still quite astounding when you think about it.

How did it end up like this? And it's really strange that there's no movement to update various systems so that they don't have to reject a tenth of the male population. Even in Sweden where I live, there's basically no discussion about this despite the relatively high interest in gender equality discussions.

Somewhere in the early design process of various signaling devices for airplanes, trains, trams, and other places where color coding is used, this question must surely have popped up?
