OK, so for comparison. When I was:

About 11-13:

- Separating the chlorophyll from grass (simmer in ethanol). Apparently the standard school experiment is then to do chromatography to show different pigments absorb different wavelengths, but I don't remember this bit.

- Flame tests for metal oxides would be here, although not the theory.

- Acids/bases and indicators. Making and testing for gases (oxygen, hydrogen, carbon dioxide). So mostly seeing who could make the most hydrogen from magnesium + hydrochloric acid, in order to make the loudest "pop" sound when it was lit.

14-16:

- Burning magnesium powder to reduce iron oxide to iron; the thermite reaction used to weld railways tracks. I think we had to calculate the atomic mass of oxygen afterwards. Presumably related to studying reactivity of metals.

- Teacher demoed making hydrogen from natural gas over a nickel (?) catalyst. Memorable for the explosion at the end, which I'm certain is what he intended.

16-18:

- Making lead oxide, the bright yellow colour that used to be the one used to paint lines on roads. Probably to study different oxidation states, since lead has different colours.

- Making an ester (carboxylic acid and an alcohol), the flavour used in old sweets [candy] that smells a bit like pears. I think this was practise for the practical exam, which I've forgotten. We probably had to measure the purity at the end.

- We misbehaved making the ester, so the other class got to pour concentrated sulphuric acid on sugar, but the teacher demoed it to us. (The sugar turns to carbon.)

- The "concentrated" sulphuric, nitric and hydrochloric acid bottles, plus the ammonia solution. Other than a test for ammonia gas, I don't remember the purpose of this.

This was 1996-2004-ish. I have no idea how the sports teams performed, that's not really a thing in England.
Less current usually means less heat generated in the wires and so you can use smaller copper wires. Higher voltage requires better insulation on the wires. Altogether I think it's a good idea to use 20V at 5A for 100W rather than 20A at 5V. You will get much more heat and voltage loss at 20A for the same size wire.

I also don't ever plan on driving, and the biggest contributor to that is probably because I simply can't bring myself to entrust my own life or the lives of others to my own poor motor skills and spotty attention span, when any tiny mistake at any moment while driving has the potential to destroy lives.
If anyone asks these questions without a particular scenario to actually deal with in the course of the position you're interviewing for, you are in for some bullshit at that company. This has become all too common at the major corporations sadly.

> That's a failure of the manager, not the programmer. The good programmers, the ones who enjoy their work, will choose a complicated but beautiful path, will choose to make a configurable workflow whose configuration is itself configurable in LISP. It's the manager job to know that the workflow can be hard-coded and then avoid complexity by the love of complexity (good programmers love complexity solved by intricate and beautiful code).

I see this as a programmer responsibility... how is the manager even supposed to know whether it's hard-codeable?

The trouble is often that the programmer doesn't get enough information to make this decision, but that's a different story.

Why would everyone's taxes be used to protect a few workers? Especially (apparently) not the greatest... If the company is doing well it'll continue to hire and provide employment to others. As a society, I believe we could argue that we shouldn't subsidize companies that offshore the work, but otherwise if we want help for employees that are let go (training, assistance, ...) better make it a public service.
Why would anyone care if your date has a car or not?
You're acting as if cables are picking an choosing tiny subsets of the spec. Reality is most cheap cables support almost nothing, and just about every expensive cable I've seen supports all of the spec currently established. It's not like someone is going to choose to support thunderbolt and then not support usb3.
I guess I meant I doubt the way certain big segments of the population using their phones changes a lot in the future. It feels like a sizable portion will still use their phones in a very basic fashion like I was describing.

> Rust doesn't handle out-of-memory conditions well.

Do you happen to know languages that do handle out of memory conditions well? That seems like an interesting topic. If I understand how it's done in C, I wouldn't call that "well", but it does provide the mechanisms for doing it (which is more than can be said for all languages). Language level features (or coding styles in C that could be implemented at a language level elsewhere) that provide for increased and intuitive control would be interesting.
most bushmen aren't healthy hunter-gatherers any more.
I think you're right. Not driving is a problem for women too, but to a much smaller degree. There are other examples where the contrast is much clearer.

Making less than $100k is nearly not an issue at all for women's dating opportunities where it's a significant issue for men.

Crying is another example.
Why aren't there more motorcycles in LA? If I lived there I wouldn't even own a car, just a bike. No winter!
NJ transit does do the minimum of express for the farther out places from NYC. Nothing as in-depth as you're explaining. But as you said. The numbers wouldn't support making things too much more complex. That's why my original post mentioned a limit or 7 stops between philly and NYC as an example of a semi-express train. Though a hypothetical express train would probably actually be 5 stops max.
This may simply be an LA thing. The entire basin is designed for cars, as a teenager having a car affords a freedom that is simply not possible otherwise. If you lived in the Valley, you can now go with your friends on the weekends to the beach, get something to eat in K-Town and watch the sunset in Griffith Park.

This is simply not possible if you tried to rely on Metro and I'm hard pressed to think of any mass transit system in the US that could allow one to get away with this.
When I was in my late teens, it was easier to ride a bike than mess around with learning to drive and getting a car. Two decades later, I'm starting to think that maybe you need to learn when you're young and reckless enough to think that driving two tons of metal at 60+MPH sounds fun instead of terrifying.

Bad question because it presupposes use of Git, and using source control other than Git is not necessarily indicative of a problem.

I think the original Joel Test still holds up well and I still use it when I interview with companies. But these questions might get to culture issues that ultimately affect code quality and developer well-being:

- Are developers/employees at the office for less than 45 hours a week?

- Are employees discouraged from answering company email or signing on after they leave the office?

- Do developers have admin control of their machines?

- Do you trust your developers with internet access (i.e. no corporate website blockers)?

Any NO here is an organization smell to me that signals poor project management, too few people expected to do too much work, or basic lack of professionalism.
Inclusion is by selection of the admin [1,2]. There are Julia implementations available for most of the benchmarks [3] so perhaps eventually they will be included.

This is an LA peculiarity. Transit has been bad for a while, and everything and everyone is very spread out, so a car is needed for most things. If you don't have one, then you're likely going to be "that guy" who always needs a ride.

edit: also it's a signal that you don't have the means to solve this problem.
I think these are good questions, but I don't think they could replace the questions in the Joel Test because they're very specific to host-your-own-SaaS-product development. The Joel Test questions are applicable to pretty much any kind of software development someone could do.
Depending on place of residence, public transit methods can be limited. Another reason (in the same limited public transit / biker areas) is indication of DUI or other problem that excludes that person from getting and keeping a car. Having a potential spouse with that kind of situation generally requires extra thought.
I do, frequently. Are you arguing that all taxation is theft, or are you arguing that it's okay to tax us as long as it's for what you want and not for what I want?

Ah reminiscing, it wasn't always this way in LA. https://en.wikipedia.org/wiki/Pacific_Electric but car companies sort of trapped us. Now we are inundated with automobiles and all that comes with them. Greenhouse gases, debt, accidents, waste, traffic. Millions of people sitting mostly alone in metal boxes that can seat 5 or 6 unable to reach out and contact the people merge inches or feet away.

I’ve been using computers since I was 7 in 1985. I never had to think about the chain of custody of my power cord until very recently.

IMHO, regulatory bodies should be taking a hard look at multi-use cords over a certain power level. It’s literally a matter of time before people die as a result of some fake Amazon cable.
T-Mobile haven't been distant fourth for a while. They have been the clear third for a few years now. Germans wanted out badly before their recent winnings.

If a deal goes through, it'll be a merger for sure. But also it'll be T-Mobile as the bigger of the two companies. T-Mobile stock has tripled in the past 5 years. They have a healthy PE ratio. Sprint has more or less remained around the same spot. Which is now half the market cap of T-Mobile. Sprint is also having a hard time being profitable.
That would be great! I don't see why we couldn't do both.
> Later, after a couple beers at Little Bear, she handed me her phone and disappeared to the restroom. I sat at the bar and debated how much my revelation had contributed to the current awkwardness when her phone flashed and the following message appeared on the screen: “He doesn't drive?

My only question is - why was she texting during a date? That's the real dealbreaker.

The GM thing is more myth than anything else, unfortunately. Pacific Electric was, at its core, a way to get people to buy real estate; much of the interurban systems in the United States can be traced back to basically being vehicles for real estate speculation.

That doesn't diminish how extensive the system was.
I lived in Manhattan for a couple of years and went on plenty of dates -- the subject of a car never really came up. The subway works just fine for most everybody.

In fact, I don't think a single person I went out with actually had a car of their own. People on this forum can probably afford to keep a car while in NYC, but consider the minimum-wage workers living there. No way the average person could make that work.

(Now, I did have my car parked off the island, but used it maybe a few times a year for longer trips.)
Not only that, but lane splitting is legal in California. That helps a lot in getting through standstill traffic.

Which one is "right" and which one is "wrong" (those are strong words I chose somewhat tongue-in-cheek) is a matter of opinion.

I have my opinion, and that is that zero is the proper number to start enumerations on, not just in programming, but for everything.
a market is broken. you can message 'we need to control this market' or 'its only broken because the stupid government has its fingers where they don't belong'.

which story plays better with the incumbents? ignore any rational discussion of outcomes.
This was my take as well. The guy was working 12 hours a day 7 days a week, with the fate of the entire project on his shoulders it's no wonder he turned in to 'Mr. Hyde'.

Management should have stepped in long before it got to that stage.
The author elaborates a bit more on how management unsuccessfully tried to reach out to Rick, resulting in their departure before Rick's in response to a comment[1]. This post is obviously just one side of the story, so take it with a grain of salt I guess.

> dated and signed

What's the signature for?
The transformation of Rick from Dr. Jekyll to Mr. Hyde is absolutely the companie’s fault. This article further denegrates Rick by lacking the self reflection to understand that it sounds like Rick was a devoted employee. He put in crazy amounts of hours to help the company succeed. Of course this had massive amounts of pressure behind it - related to the transformation. The company rewarded his devotion by firing him. As anyone would, Rick saw his hours of toil being stripped from him, anyone would be defensive in this situation. Perhaps this departure might have been good for Rick too, but it seems like it could have all been handled in a way that could have been copesetic for both parties. One way might have been telling Rick what the company felt, give him a nice long vacation to unwind, have the team collaborate in his absence. More creative and effective solutions probably exist.
I am a woman. I gave up my car some years back. At one point, I was asked for a date by a guy who sometimes gave me a lift home from work when I had a corporate job. He was a senior programmer who likely made several times as much money as I did.

So, my firsthand experience suggests I'm right. ;-)
I grew up in Boston and lived in NYC for 4 years. Never learned how to drive until 2 weeks ago (age 29) when I moved to... Los Angeles.
Wait a minute. Having an arbitrary offset is one thing. Settling on 1 as a standard is another one!
It's not reasonable to call it a refinement when it removed the central feature of the Audio Data API (feeding samples). Web Audio was a competing API, designed by a former developer of Core Audio (at Apple) once he moved to Google. They shipped it without a standardization process, at which point it became the de-facto audio API for the web.
I definitely recall seeing complaints about Thunderbolt (and I can't remember if I ever commented publicly, but I definitely thought it was a poor decision). Even so, they were probably less frequent due to the relative uncommonality of mini-DisplayPort, and mitigated by the fact that it was essentially MDP OR MBP+Thunderbolt - relative simple next to the variety of modes/standards USB-C can use.
Completely agreed XD

The Javascript community is something of an echo chamber, and often thinks it is innovating when actually it has rediscovered spokes, rims, and axles, and is now starting to wonder if they can be combined into some form of rotating load-bearing device.

TMobile doesn't need Sprint. They've been growing great and adding users for years, and just bought nearly all of the 600mhz spectrum.

Sprint has, by any objective metrics, the worst coverage and speed. It had been an awful company who keeps taking wrong steps, is outdated, and not making much investment. I'd rather the merger not to happen, as competition is good, TMobile doesn't need Sprint, and Sprint by some miracle still has a fair amount of customers.
Terrifying mostly for whoever you hit, or whoever hits you.

Sad reality :(
>I'm hard pressed to think of any mass transit system in the US that could allow one to get away with this.

That is a combined failure of US city planners and US transit systems.
There are people who can get away with being bad drivers for decades who would have been dead a long time if they drove a bike. Especially in L.A. where it requires a good degree of both aggression and defensiveness to not become roadkill. I don't think it's too much of an exaggeration to say that motorcycling is a sport, and not just a different mode of transit.

Unfortunate though that L.A. doesn't have world-class bicycle infrastructure.

Deliberately disclosing your "shortcomings" is demonstrably a poor dating strategy, you lower your chances by doing it.

You don't see supermarkets advertise by saying that their product line is short, or their warehouses small.

EDIT: Checked the author's twitter (there's a link in the article) and he seems to have low self-esteem, judging by both the article and his "about" on twitter.

Low self-esteem creates a vicious circle of self-deprecation which is not going to help you succeed in whatever endeavor you embark on in life.

Next thing you know you come up with all sorts of rationalizations and excuses about why you will fail. The "I've got no car" is an ego defense mechanism to protect yourself when the date goes nowhere. "Yeah, it must have been because I had no car", when in truth, it was a combination of a number of factors, low confidence and self-doubt stemming from it is particularly repulsive to women.

Dunning-Krueger is king, while Impostor syndrome leads to ruin.
One of the biggest difficulties with outsourcing is also one of the biggest difficulties with software in general: sufficient specifications.

Hardware production outsourcing works well. You design the product, prototype it, create a specification that describes every necessary detail, and find a company to make your device. This engineering design process is expensive but does work well. Your onshore workers are the engineers, designers, and the like. Your offshore workers are the production staff.

Software production outsourcing works poorly. Creating a thorough enough specification for production is exactly as difficult as creating the program. You have all the same types of onshore workers, but there's no production staff!
I am absolutely not denying that, but it's particularly acute in Los Angeles. I am optimistic given the aggressiveness that Metro has had in recent years about growing out the light rail, that it'll get better...as long as it doesn't turn into BART.

The key point being:

"He never should have been allowed to take on so much. If it gives comfort to anyone else reading this, the manager went first because ultimately management bears responsibility, always.

I was brought onto the team after that, as a hail-mary pass."

The original manager screwed up to let Rick get to that point, and once at that point it was impossible to manage him, hence him getting fired.
I think New York and Chicago are both very good in this regard. San Francisco and Boston are not great, but doable.
