The first computer I ever owned was an analog computer from Edmund Scientific. It was fundamentally an electronic slide rule. It had a meter that swung from a negative value to a positive value. The operator adjusted some potentiometers so that the meter was nulled. The output was read from the numbers pointed to by the knobs on the pots. At least that is the way I remember it working. I don't recall how exactly the equation was entered, but I think there were some pots for that too.

As far as building your own analog computer, look at op amps. They're called that because they perform mathematical operations, such as summing, multiplying, and integration. Of course they do the inverse operations as well.
Even in this thread I see a lot of people conflating consulting with working as a highly paid contractor. I accidentally fell into contracting two years ago when the company I was working for closed unexpectedly. I doubled my yearly income, but I'm still an employee in practice. I will say though, if you can make the leap to contracting with large companies, the pay is insane. I'm currently making about $60k/year over the highest paid salary jobs I could get anywhere else here in Austin, TX. I have to buy my own insurance, but I'm single and childless so it's not a huge deal for me.
I used to use Solarized everywhere, and it's still my fallback. I like its consistent colours, and I use the darker colours as my wallpaper on my desktop/laptop.

I've switched to using One Dark in my editors though, it feels slightly easier on my (aging!) eyes.

A lot of people use Solarized, I think, because they are not happy with the defaults, and Solarized is very well put together. So when people see the new colours available to them, they think "this is great! I should use this everywhere!" and thus it gets potentially way overused.
I wonder if any countries are trying to weaponize this?
> Explicitly logging a password is one of those practices that doesn't sit on the backlog.

If that is your experience, then that's a truly wonderful thing.

Might it be possible that at many companies, teams with deadlines to hit will tend to prioritize feature work over details like this? Perhaps especially so when teams are not rewarded for fixing vulnerabilities and are punished for not meeting deadlines? Particularly when the actual bug at hand is that the full contents of a POST are being logged, and a PM might not read the ticket enough to understand that this includes a password...

Again, you're completely right in every way about what should happen. It just could be possible that this could reflect something other than all experiences all software engineers have had.

It would be interesting to know more about your personal circumstances and how you set yourself up for success here. I feel like we need to start planning long before we get burnt out. For many people it's hard to avoid things like mortgages, or other situations which impose a financial burden of some sort.

I personally think 10 months off for me would be healthy right now in a lot of ways. It would be survivable financially, but in some ways it would drive a lot of anxiety for my partner and I. The support system doesn't exist for this in the US in the same way it does in other nations either.
Ask HN: Technical Screen for PM
Hey! I’ve got a technical screen for a PM role next week. Based on recruiter I will be asked about:

AWS
CI/CD
Previous applications/if any knowledge transfers.

The PM role is at a 2bil company building out internal tooling.

What should one know, read/watch to prepare?

My experience is previous saas founder. Wrote entire codebase (albeit, very sloppy because we needed to sell software) and sold first 100k. So in theory, I think I’d be a great fit for running a new product from the ground up. But would love some resources and advice from the smarter engineers here! Thanks.
My personal experience: Having a successful consultancy depends on producing the best products for your best clients.

Which means it depends a lot on your ability to find clients, and get rid of the bad ones.

Bad client meaning the one costing you money, for example by not paying the invoices, or always wanting free stuff.

So ask yourself, How do I get good at marketing and sales? How can I sell the project bu subcontract the developers?
> I'm perfectly okay with him being locked up until he decides he's had enough and wants to straighten out.

The problem is that prison does an awful job of causing people to figure out that they've had enough and preparing them for walking the straight and narrow. Instead, it indoctrinates them in a culture which is harmful to that reform. The results prove that fighting that peer pressure, while literally locked in it for 2 years, is really hard. And that produces a vicious feedback loop where, after you're out, people think should be back in and segregate you socially, educationally, and financially.

> UTF-16 allows to quickly index a char in a string covering the most languages that way.

Nope. UTF-16 is not UCS-2 anymore for multiple reasons. You cannot assume you can index a UTF-16 string as if it was UCS-2 anymore. UCS-4 (32-bit) is a possible option, though not generally recommended either.

There are multiple tricks for getting great performance in UTF-8 string processing such as codepoint maps of various sorts. It's quite well suited for string processing, and it's better to use UTF-8 at this point simply because it also helps from falling into the UTF-16 is not (and has not been for some time) UCS-2 trap, and UCS-2 cannot represent a lot of Unicode today (including many emoji).
While it sounds bad when you put it that way, the psychiatric infrastructure that existed before was evil. As bad as things are for those who need help, they are probably better living on the streets than in those institutions.

I knew someone who was in an orphanage (not the same as psychiatric, but similar problems existed there I just don't have anecdotes to share) in the 1920s. They would beat him with a chimney brush if he slept on his pillow. They got awards for how nice their beds looked (since the pillows were unused they always looked new). They used a chimney brush because the metal bristles would hurt without leaving large marks on the body.

While you could argue (and I would agree) that we can do better today I'm not convinced we actually would in practice.

I grew up in England. My father is British and my mother American.

We owe it to people to give them human dignity up to, and including, their last breath. Anything short of this is crass, careless, and evil. The West has always tended to value human life more so than other cultures, but in the last couple of decades, we have devolved horribly on this point.

When my first wife died of cancer, I did ridiculous amounts of research into costs. Pharmaceutical companies are utterly shams. They may make life-saving drugs, but at what cost? I learned that they intentionally manufacture as cheaply as possible and charge as much as possible. Look at the recent shamelessness with the Epi pens. Those cost very little to make. They would still see a profit at $20.

When my wife died, the chemo she was getting was $12k for a 500ml bag. Cost to manufacture? Less than $100. That is not a profit, that is outright effing theft.
We ran our entire infrastructure on AWS so I guess I’m familiar but know I’ve got blind spots.

Running a design agency for over a decade, I've seen the price of logo proposals drop from €5K to about €1K. To most people, a logo is just something they want to use on their social channels and their website.

I don't think that's wrong. There's still room for an elaborate creative process of designing a company brand. But that's more for the bigger companies. The freelancers, startups and side-project hustlers usually just require "something nice".

Realizing all this, I recently launched an automatic logo generator: https://mybrandnewlogo.com

I think it strikes a nice balance between "something nice" and an affordable price. Not every logo is good, but tweak or generate it long enough and you quickly have something that looks good and is very affordable.

For $5, it's almost impossible to deliver something of quality. Even running a logo creator, you still have fees for using an icon library, hosting, etc.

I find the authors definition of functional programming really insufficient. FP should not be defined in terms of immutable state, but as mathematical functions as the basic form of abstraction, and that programs are composed as an evaluation of a single expression in spirit with the lambda calculus. Immutable state is just a correlary.

With that in mind, you really can’t do FP without automatic currying and the function composition and application operators (. And $) in Haskell. Without these, you lack the key components needed to work with your only means of abstraction. Language author seem to think lambdas are enough, but if you can’t compose functions to build new functions, partially apply them to get specific versions of behavior, then you aren’t going to get very far.
I wonder how close this process is to hydraulic fracturing to extract fossil fuels. Is the volume of liquid pumped into the ground similar? I imagine geothermal is pumping more and deeper to get to where the earth is warmer, but I am not sure.

In my area, Pittsburgh Tristate area (WV,OH,PA) fracking is big business. Seems we are fortunate to not have a major fault line running through the area.

edit - clarifying that I am talking about fracking for fossil fuels
Making healthcare more expensive doesn't make it better.

As an example, the price of Clopidogrel (Plavix), developped in France is sold 5x more expensive in the US than in France. Do patients in the US experience better outcomes by paying more? No, it's the same drug.

"Providing more" for healthcare, means better overall health, fewer avoidable deaths and longer life expectancy.

"Hot Dry Rock" geothermal was pioneered by people at Los Alamos:

http://coloradogeologicalsurvey.org/energy-resources/geother...

It was a strange story. It started out with ideas for
super-high-temperature mobile reactors that could melt
a shaft ten miles down to tap geothermal energy. In
the early 1970s the enthusiasm for that kind of thing declined, so they got an idea to tap geothermal energy
using "fracking" technology which existed back then but wasn't anywhere near as capable as it is today.

One thing I remember about their work is that they didn't observe any fracking-related seismic activity at all: when you frack sedimentary rock you get the rapid formation of large cracks with obvious seismic activity. At least in that experiment they found that fracking would open up micro cracks in bedrock slowly and that there was no obvious activity from it.

Pushing back against this part but in support of your larger point: many of us don't really have that option due to chronic conditions. Society incentivizes us in various ways to hide them when we can, so people mostly don't realize how prevalent these conditions really are. By some criteria, American adults with no chronic conditions are in the minority. Much of that is due to hypertension and hyperlipidemia being their own diagnoses, but to pick one example, overall asthma prevalence may be as high as 8.3%. [1] [2]

If we really assume data proves (I never saw a proper argument for that same data that just didn't choose to ignore quite some important other pieces of data) that the US system is intently racist against people io colour, than - that same data - proves even more strongly that the US judicial system is inerently sexist against men.

It's the same (flawed in my opinion) argument and the same data, but only one part of it is ever mentioned, which leads me to believe, this is just ideology at work.
Unless you compare that to the number of people who became rehabilitated, that is just anecdotal evidence, though.

I've heard it a lot, too. But "a lot" means still less than 100 times. There are millions of prisoners.

Not saying it isn't the case, just saying I'd like to have more data.

It’s never been tried paying people to not commit crime has it so both of our theories need some testing to proves who is correct. I personally think it would be very effective; it’s not as if there would be no consequences for repeat offenders or people who took the money and carried on breaking the law. I don’t think you’re thinking clearly about what I’m suggesting at all.

One thing we 100% do know is that jail is not working to stop reoffending in the vast majority of cases, and as the article suggests this is at great expense to the tax payer.
This principle was used in medieval disputation. The Summa Theologiae [1] of Thomas Aquinas is broken down into "articles" that examine every aspect of a particular broader "question". Each article begins with a series of "objections" that attempt to state the best possible arguments against the position that Aquinas will take. The next section has a relevant quote from authority, and then Aquinas explains his position. Finally, he provides an answer to every objection. Although reading something written this way is difficult for modern readers, I think it provides a healthy antidote to the craziness we have today.

> Once you can build higher the costs diminish since most of the cost is opportunity cost of the parcel of land it's sitting on, not the building itself. A real rise in supply will counteract rising prices. You can build 8x 100m^2 apartments for way less than 8 million.

It's not that simple. Higher buildings need to be stronger, and they need elevators.

The are absolutely areas in the city that could have higher buildings, but plenty of areas in the city already have them. There are plenty of large apartment blocks in West, North, Buitenveldert and Bijlmer.

Inside the Ring, sure there are areas that could have higher houses, and I'm not necessarily opposed to that, but it's not going to gain as much extra houses as you think. Up to 4 floors, having no elevator is considered acceptable. Higher than that, by current rules, you really need an elevator. Do you want to have people walk up the stairs for 6 floors? Or make all the houses smaller to make space for an elevator?

There are trade-offs involved. It's not simply a matter of taller houses therefore more affordable houses.

I believe by the current plans, they intend to build high rises on Zeeburgereiland, but I've seen a very convincing argument that you can house just as many people there with lower buildings. The gain isn't as big as you'd expect.

In the Bijlmer, they're explicitly moving from large apartment blocks to low single-family houses. I don't know what the reasoning behind that was exactly, but I suspect some lessons were learned there. Maybe people actually do prefer lower houses. They're fairly affordable, and people actually get to have a yard, which is a rare luxury in Amsterdam.

I don't see the need to pack as many people as possible in the city. The city has to remain livable, and as far as I can tell, the city is doing a really good job at that. They do try to fill up all the unused spaces in the city, like de Omval 20 years ago, and Zeeburgereiland now (I'm still surprised they built IJburg before putting Zeeburgereiland to use).

It's not really a bubble when it's based on real supply and demand. The city actively tries to reduce speculation with measures like the one from the article, but because it's such a nice place to live, lots of people want to live here.

I don't see any reason for Amsterdam to become a backwater, and there already are plenty of jobs in Rotterdam. There are other towns around Amsterdam being built up, like Almere, Hoofddorp and Purmerend. Of course the Amsterdam will keep looking for places to create new houses, but opportunities for that will remain limited.
This is actually a missed point in modern times. If people could ask to get lashes or prison, I bet a very large number would choose lashes.

So which punishment is more humane? Turns out we are picking for the experience of "the innocent" not for the rights of the "guilty".

In these lines I have commented before: the main moral issue of modern prison systems is that they don't value liberty, so merely taking away someones liberty does not quench the thirst of revenge that pays off for the politician rhetoric.
