Efficiency is everything. Transporting fuels is even more cumbersome than transporting electricity. At only 10% or even 20% efficiency, you'll have a tough time to recoup the energy it took to built the plant creating the synthetic fuels .... Sorry, but Math and Physics is not on your side.

Some related threads from a few weeks ago about rising computer illiteracy among kids:

https://news.ycombinator.com/item?id=21237540

I really have noticed that elderly people who have no computer experience have a better grasp of computing concepts than most kids. They understand physical media stores sounds and pictures, so it easy to explain that pictures and music lives on their sd card, like a phonograph or roll of film, except much more. They understand that you need an internet connection to communicate, like how you need your phone hooked up to make phone calls, since they have all had to deal with the phone company to get their phone working. And it is really simple to explain that a wifi router is just extending the internet into your living room. They understand sending an email and attaching a picture to it (use the paper clip and pick the picture). I was even able to explain the file system to someone, by saying that instead of just printing out his letters, he can store them inside a "folder", and print them out later as many times as he wants.

These concepts seem utterly lost on so many kids. They will send you a series of screenshots of a website instead of just sending the url. They are constantly losing data. They can not tell you where their data "lives"; whether it is in their iCloud or their phone or whatever.

It's not that horrible, but I am disappointed because I honestly thought that by now we would all be more computer literate. Isn't this what schools are supposed to teach?

Most forensic tests are quite broad including GSR and blood residue.

It’s not about what else they trigger on but how likely that this would be the case in a set of controlled circumstances.

A cocaine test that triggers on bird poop is still completely acceptable unless carrying bags of powdered guano is the new rage these days.

Same thing with a GSR test that may be triggered with certain other chemicals, you only get reasonable doubt when there is a good explanation why would you’ve been exposed to those chemicals nominally.

BTW medical tests aren’t that different, it’s up to the doctors to make sure they exclude all other possible explanations besides what they are testing for and we don’t really complain.

What do you think of the permissions associated with Android apps? Each developer gets a separate and cordoned user account on your phone. They only have access to private storage unless they request it through special APIs.

Android apps are run in containers, for some broad sense of the word. That's how it should be. Every app I run should be run with a simply configured set of permissions, and "per app" or "as user" makes sense, even in the desktop space. That's what snap originally tried to do (but failed at, and have now broken)
Yep. You just nailed my latest hiring experience.

I moved on triumphantly from my previous programming job where I built a company's product from Greenfield to million a month with awesome performance and features.

Other start-ups in my area are offering me 5-10k more than I was making at my last job to do the same thing again. My counter offer from a large company was 50k higher for a laid back environment. Guess which opportunity I took.

Hilarious to me. One lead engineer is worth three junior engineer at least. I see startups doing the same thing over and over again. Hiring Junior developers fresh out of boot camp who are completely worthless, and refusing to spend money on high quality candidates who are interested.

This is a really common question and I’d be happy to elaborate.

I don’t collect any referral bonuses from google nor do I provide any internal google questions to students. What we do is teach data structures and how to communicate these ideas in an interview setting.

The parts that’s “gaming” is that the interview process is quite standardized which I’ve found a way to prepare others for.

Regarding conflict of interest, big tech companies have decided being good at hackerrank interviews = being a good engineer. So I’m training good engineer in their eyes which is a good thing for tech giants.

Normally when I see a language that was created to fix problems somebody had with another language, then the two languages tend to be syntactically similar. I don't see any syntactic similarity.

Secondly I don't believe that GraphQl is meant to map to the relational algebra, which is the genesis of SQL.

GraphQL's benefit seems to be that you should be able to get all the data you need and nothing more with one query, and get it back in the form you want it. In the earlier comment that started this thread the commenter said something like that's what SQL gives you, but from my experience if you want to get back complicated data (3 joins, many properties with same names) your SQL statement is going to be a lot more difficult to write and organize than your GraphQL query. Writing the queries is generally really straightforward and it is quite quickly clear how to structure a query to get what you want, and indeed if it is even possible to structure the query. Ease of declaring what you want is a valid reason for having a new language.

Structuring a query in SQL or most query languages are generally more difficult than in GraphQL - in my experience. This of course does not mean there are not places where it can get complicated - just generally not at query construction time.

I can't really say if having a new infrastructure is a weak reason for creating a new language, I guess that depends on the infrastructure that one needs. Languages are generally really powerful tools for doing things, so if you want to do difficult things with higher productivity than previously you might feel encouraged to create a new language as part of your endeavors.

People usually think of incentivizing R&D in general, but patents also help to prevent trade secrets.

A trade secret can be kept secret indefinitely and can potentially be lost if the company loses interest or is shut down. Patents help encourage publishing advances in technology so that they eventually advance the public domain. If they weren't interested in that then they probably wouldn't make patents expire.

Someone who has a very large house with very large grounds paying for additional private services for fire protection seems _fair_ to me. Should the public pay for the increased cost to cover someone with a house and property much larger than what the median home and property is? The wealthy are stepping up to the plate and paying for the additional services they need without public help. And keeping the fires from spreading though their own property will no doubt have a beneficial effect on those around them, too.

> One lead engineer is worth three junior engineer at least.

Far more, I'd say. Fresh graduates and juniors are often held to almost no production bars at all. In many startups, you could be a junior for a year, accomplish very little, yet be in no danger of failing any performance metrics.

Before I left the startup world behind, I observed that seniors were often held responsible to 95% of the production that was happening at their startup.

You'd expect them to be paid x10-20 times as much as juniors, but instead it's typically no more than x1.3-1.4.

So as a senior engineer with a track record of shipped projects, I get to work harder than all juniors, be held to x20 their performance metrics, and for that I get 30% better pay?

No wonder every single senior engineer I know has a "FAANG or bust" attitude nowadays.
