I have an MSW and quit therapy (though to be fair I was mostly doing policy-level and community-level work, not individual counseling type work) to become a programmer, but occasionally I think about going back. Good read, thanks!

I definitely think nearly anyone could benefit from therapy (and a lot of people could benefit from a few strong psychedelic sessions where they are willing to ask themselves what they really want to do with this one precious and fleeting lifetime) and I applaud the courage it takes to listen deeply to oneself and strike out on that path.

We could for sure benefit from a lot more humans asking deeply and honestly "Does this make me deeply happy and what effects (if any) do I want my work to have on other people's lives?"
4th Order Properties Part 2: Association Relations in DB Design – An Example
I like the idea. But speaking as a research mathematician, I cannot imagine that such a system will can be adopted in the math communities. You have quite a lot challenges to solve in this domain:

1. Only very few people actually read a certain paper. Of course it depends, but usually papers are only interesting for a handful of mathematicians world wide.

2. The access to papers is not centralized or can be controlled. You cannot know who read which paper. Often preprints are circulating via email. Published papers may be behind a pay wall.

3. How do you want to detect whether somebody really read a paper, let alone understand it?

4. Surprisingly many mathematicians are eccentric and hostile against computers (and programming). E.g. older people refuse to use new tools like LaTex and prefer TeX. I only know a few mathematicians, who use git/hg to make collaborative writing easier. Usually people emails documents back und forth instead. Cannot imagine, that a critical mass of mathematicians starts logging into some fancy new app. I also suspect that many people don't want to be tracked for what they read. After all, research is competitive.

Cannot speak about other research communities though.

>That makes it harder to feel welcomed.

Bending over backwards to make big displays that everyone should "feel welcomed" is just the culture of the city you're used to. And lets be honest, it's all for show. That doesn't slow down any of the social interactions which make it obvious when someone is unwelcome.

I don't think the almost anywhere assumption holds for several reasons - a bad cultural climate can be a sure turn off (anti-intellecutalism and open bigotry), a "good" one can be a pleasure, and employees prefer to have plenty of alternative employers.

There are multiple reasond - security from layoffs or bad workplaces, job-hopping is the defacto way to raise salary, and it also keeps them having to compete for them some.

A middle of nowhere job sets off "it's a trap" alarm bells consciously or unconsciously as an isolating move.

That said there is a lot of range between "most expensive areas in California" and "cheap one company towns".

I suspect sprawling out to network edges would maximize benefits for costs similar to Palo Alto once being the cheap option.
I was looking to see if they anneal the brass; maybe the process of removing the solder heats it enough for that, or maybe the brass used in this application doesn't require it?

I'm restoring a 25 year old car, and discovered that new heater cores for it are no longer available. Both my original and the used spare I got were crushed on the tube ends (from people using vice grips to remove stuck hoses). I never had much luck reshaping aluminum or brass, but I had recently read about the process of annealing (which restores plasticity to a work-hardened metal piece) so decided to give it a try. (As for how someone can be in the habit of attempting to reshape metal and NOT know what annealing was: such is the life of a self-taught DIYer.)

I used propane with a turbo-torch tip to heat the ends of the brass tubes cherry red, and let them cool. Then, in a process very similar to page 2 on the linked website, I used an internal mandrel (a thick steel pin) and gentle taps with a flat hammer to reshape it. It was amazing to see the capital letter "B" shaped crushed tube ends become round again. The first few strikes move the metal easily; after that each tap makes the metal harder. I could fix any mistakes by re-annealing and starting over.

there's definitely a steeper muscle learning curve with a trackpoint but once you get past it they are fantastic to use. I find accuracy higher and less of a jarring transition from typing to mousing. if you get one again, I suggest persevering (it took trying to play populous 3 on my dad's laptop Back in the day to convince me that a trackpoint was the way forward. I pushed through the mental barrier and found that P3 was an order of magnitude easier to play on a trackpoint than a touchpad) since then i've been a convert and actively stipulated that my last laptop HAVE a trackpoint.

It is probably first mover effect. Bay Area had silicon valley. Remember silicon? Many things involving semiconductors and electronics grew up in the Bay Area because of Fairchild and the traitorous 8. In fact, you could make the argument that the first generation of electronics businesses involving vacuum tubes were in the area as well (in Oakland). Software companies growing there happened later when the semiconductor money needed something to invest in, and computers were something semiconductor people understood.

Nobody wonders at Wall Street being a center of finance after some 18th century traders met under a buttonwood tree, nobody wonders at Hollywood continuing to be a center of film and TV production, and nobody should wonder at Bay Area being a center of software development.

All the remaining HFT firms (there's not that many left) have moved into FPGAs and ASICs as well. HFT is interesting because it's not really that finance related at all. The kind of people that work at HFT firms (at least the ones I've met) are exactly people like you're talking about: hardcore CS/EE guys. Some of them don't even care about financial markets at all, they just know how to program some blazing fast C++.

I personally find HFT kind of a snooze and not especially intellectually gratifying. Most of the work is just wading through bullshit (write in interface to some random exchange , figure out how to remove an instruction here or there).

Imo, things aren't looking so good for HFT. The profits are very slim at this point, and staying competitive is becoming exponentially more expensive. The golden years of super-normal profits and fat bonuses are over.

Because no vacuum
There is a severe workplace burnout problem in IT(especially MSPs); which when not addressed grows into bigger mental health issues and even literal sicknesses.

There just isn't enough skilled IT people. The industry is immature and is bottom heavy. The top performers and seniors, are then overwhelmed with work and the business is unable to hire more senior people to reduce workload. Then the business keeps growing and eventually you get a death spiral of people quitting and making the situation worse.

>I started asking myself questions like — "Even if the projects I'm doing succeeded beyond my wildest expectations, how would it affect people?

IT is so inherently negative as well. In my last job 1 person and myself were the only people trying to stay positive. The other people in the office had succumb to the negativity and would even attack us for being 'mr happy'. They were literally so negative that they just attacked positivity.

I had places where I would go onsite to resolve an emergency. I never caused the outage, I was there to help. I would still get death threats from clients. "The accounting files are the server, if you lost them I'm going to go to your office and kill everyone." My employer wasn't even their IT, their IT person quit upon discovered 2 drives dead on the raid 5 array and no backups.
I used to make PCBs at home, first using toner transfer and ferric chloride (never again, impossible to avoid staining everything in your lab), then with a UV lithography mask (photoresist and a laminator) and an exposure box used for making stencils. The UV stuff is actually pretty good, you can easily go down to 0.5mm pitch with some practice. Etching is still a pain, but I started using a clear etchant (sodium persulfate?) which at least didn't stain everything. I briefly experimented with laminated and cured solder masks, but that's also tricky. Never got round to silkscreening, though apparently you can do it with coloured foils.

Drilling is a pain in the ass. The bits break easily and drilling accurately, even with a press, is hard. Milling makes this so much easier. Then you need to think about plated through holes, do you rivet? Do you just put some 30 gauge wire and solder?

Nowadays I find I rarely need to rush boards and Oshpark is so cheap it's ridiculous. There are cheaper companies (I've yet to try Dirty PCB), but you get 3 boards, ENIG and really good tolerances for free. Even rush shipping ($20 international fedex) is cheaper than getting it done here in the UK. The only competitor I've found is Ragworm, and they're both more expensive and you only get one board with HASL.

Unless you really want a board made now, I would say just get them made for you. The quality is so much better without spending tons of time. Of course sometimes you really do want a prototype instantly and if you want to make a weird shape - perhaps a really long rectangle that would cost a fortune to get made, it's worth having the kit in your house to do.

On the milling side, I'd be tempted just to buy a Spokeo mill which can apparently do reasonably good PCB milling. Costs a lot, but at least it'll do other things as well.

I've recently got access to a lab with some very expensive rapid protoptying kit (from LPKF), which I'm keen to try out. It can even do 3D PCBs laid onto plastic components.

> A thorough investigation means potentially losing hundreds of billions of dollars.

I mean, even from a financial perspective: If a third one crashes, Boeing can deliver its 737 max8 to the graveyard. Not to mention the lost trust by ignoring the obvious signs.

It is possible that these two crashes are unrelated and that it's simply bad luck that it hit the 737 max8 two times. But that's are serious gamble with the reputation, not even considering possible fines and lawsuits.
If we're plugging tools we use to make Debian packages without dealing with the insanity of Debian tooling, I use debbuild[1] with OBS[2] for the bulk of my packaging at work for Debian/Ubuntu systems.

As it turns out, it doesn't take that much effort to make packages that comply with Fedora/openSUSE Packaging Guidelines and Debian Policy with this tool, and it has drastically simplified my ability to maintain software across distributions in a way that still cleanly integrates with the distribution platform.

This is how the Spacewalk Debian/Ubuntu client packages are built[3][4], among many other things. There's also a few other examples out in the wild[5][6][7].

At least for the stuff I make for myself, I haven't made packages that fully pass lintian, but it's not terribly difficult to do if you want to.

You are talking about software engineers in general, so it does matter whether people you have in mind are software engeneers or good representants of average software engineer.

Fiber optic cabling won't transmit at the speed of light due to the refractive index of the medium. So it's slower than the speed of light in a vacuum or atmosphere.

If you want to record your desktop in Linux with a live webcam overlay I strongly recommend Open Broadcaster Software, aka OBS.

https://obsproject.com/

OBS lets you combine multiple sources easily including adding static and dynamic graphical overlays and is basically the what all of the streamers are using on all of the three platforms Linux, macOS and Windows these days, and aside from being able to stream live to Twitch etc it is also perfect for offline recording.

However, OBS is not a video editor, so if your use-case is to first record your screen and to then record the commentary afterwards rather than commenting while you are screenrecording then OBS is probably not what you want.
Not really. You dump lots of nasty material into the air, and then are left with lots of nasty byproduct that needs to be dumped somewhere.

The way to deal with plastic, especially packaging is to have a regulatory framework that makes it more expensive than putting it in a cardboard box.

> By most objective measurements, their civilization was in an earlier stage than say, Ming China.

Yeah, Tenochtitlan had a meritocratic system of governance, universal primary education, ...

History doesn't work according to a Civilization-style tech tree. A lot of the technological development is driven by the needs of the immediate area. Maize, the staple crop of the Mesoamerica, is actually a superior crop to rice in terms of caloric yield per acre (and the genetic engineering it took to turn teosinthe into maize is amazing--far more involved than the domestication of wheat or rice). Tenochtitlan didn't use wheeled vehicles because it was built on a large lake bed and you could use flat boats to move a large amount of goods.

The New World was probably more populated in 1492 than you think it was, and newer archaeological evidence is starting to show that what we thought were "empty" lands of people were actually fairly densely populated--say, the Amazon rainforest. Pre-Columbian Americas are usually now figured at about 100 million people, which would be more than contemporaneous Europe and North Africa in population.

My GTX 1080 works flawlessly with Linux, as has any other NVIDIA graphics card I've ever owned (GTX 680, 480).

I bought the AMD card based on the myth that AMD has better linux support...

When people colloquially say "speed of light" it understood to mean the speed of light in a vacuum. Light travels slower the higher the refractive index of the medium its travelling through. Saying "nearly the speed of light" indicates that the light is travelling through a medium with a refractive index very close to 1.

Well then you'll be happy to hear that the era of exotic derivatives is mostly over. People nowadays just want to trade standard products (vanilla options, stocks, futures, etc) very quickly.

And the reason startups like VC vs public markets is because they can easily get money on the secondary markets. Going public is a lot of work and comes with a lot of rules. The only reason people did it during the dotcom boom was there was a lot less secondary market capital sloshing around. It wasn't because the stock markets were somehow less "predatory" (whatever that means) back then.
