It doesn’t seem unreasonable for an SRE position. Presumably the focus of the interview would be quite different if you were applying to work on, say, V8 or the Go compiler.
I find this a great list of behaviors to consider when you are in a leading role, maybe even if you are not in such a role, as it reflects well on your job.
Love what Zerodha has built. By opening up their platform they've allowed multiple startups to mushroom. As you pointed out, smallcase is one of them (I work there).

Thought I'd point out that Zerodha Coin, Groww allow for investing in direct mutual funds. On the other hand smallcases are quasi-ETFs. Basically a smallcase is a basket of stocks tracking an idea, theme, strategy, model.
IIRC, the average developer output is 10 lines of code per day.
> But until such an interaction occurs, the electron has been acting like a wave all along.

What does that mean? Most interpretations of quantum mechanics consider the wave function to be an abstraction to model the system, not something that is actually tangible. Even in theories that consider it real (e.g. De Broglie-Bohm) it acts as some sort of field, not something that actually occupies space.
Oh, there is that, but it's too far away to be useful.

If I could set up a custom keyboard shortcut for the service, it would work great—but support for custom keyboard shortcuts also doesn't work in macOS Firefox[1]! (Unless you set a combination which Firefox doesn't already use for something, and it already uses everything sensible, so you have to set something long and annoying.)

I was asked that question 2 times in different companies. At the first time I apparently forgot the the Hour stick will move a little bit when the Minute stick move to 15. I guess it's a trick question when we can easily forgot that fact. My brain is train that way that when it's 3 then the Hour stick is at 3...
Thanks for sharing! I also wrote a Chinese segmentation and parallel translation program, with colours for the tones. Mine only takes one definition for the literal translation though, unlike yours which only handles a single line but with more translations.

I remember reading a book where someone at apple said "Why can't macos just execute windows .exe files?"

Although this person was technically qualified to ask this question, the important point was there was enough power for people to take pause and consider it.
Bonus: when you have the highest effeciency, the next step is to help other boost theirs. I think this is something important too. Some people get to the 10x point and think itis enough. It is not. Your team has to be too. If you are the only one, you did only tiny part of your job
You live in an extremely rich country, surely you can afford to install an AC unit if it impacts you as much as you're saying.

Seems like that has a much better shot at solving your problem than waiting for the world to address global climate change.
Yes, I wrote https://pingtype.github.io for Chinese word segmentation to help me learn.
On another note here a a few claims framework authors make which are usually short sighted

1. Frameworks promote code reuse

Frameworks however don't promote reuse within different versions of the same framework, which makes the code reuse claim hypocritical at best.

Where is the code reuse between Angular 1 and Angular 2 ?

Libraries also promote code reuse by the use of shared object files (C) or modules (Python, Node.js ...) and it is usually more long lasting.

2. Frameworks are easier for beginners to use

Frameworks get difficult quickly once the initial use case is run out. Frameworks appear deceptively simple because they hide complex code under the rug, but anytime you need to do functionality similar but different to that initial complex code, you will have a problem.

With a library, you can inspect the code ... copy it and edit it to do what you want, it is not as simple with frameworks especially when you have to deal with 100 levels of inheritance.

In a way frameworks encourage code illiteracy.

3. Frameworks are not composable

Using two or more frameworks is next to impossible because of all the assumptions frameworks make. Frameworks are totalitarian in this regard.

4. Object Relational mismatch is real

By forcing the object model on everything, it makes understanding non OO models for data, which is most data ... very difficult.

Relational model is more generic as it supports references and is obviously more efficient.

I find that the interviewing style of a company is often very telling of its' general work culture. You've missed our on opportunities and had to settle in less prestigious jobs, but are you sure they would've fulfilled you any better.
Most of these models will be proven inaccurate. If there’s anything “climate scientists” have demonstrated over the past 100 years or so, it’s that they have little to no understanding of the global climate. Have any of their “predictions” aged well?

Offtopic, but I think that languages should have special float types that trigger the use of fast math. That way, a programmer can better control which parts of a program are done with approximate floating point operations.

I needed that laugh, thank you!
Actually I (never took an algorithms class, so I would definitely have to brush up on execution of the basics there) thought this questions were not that bad, the newer reports seem much harder (or are plain exaggeration by the "leet"code community).

I'm also a bit puzzled about the trick question being mentioned at that. That's just primitibe (maybe I'm a little bit burned by that as in 5th grade or so, our teacher did a test, writing times on a sheet and making us calculate the angle between clock hands (and it was a lot of numbers on that sheet))
It's kind of sad what happened to r/india. I've been visiting the sub for almost a decade, it has turned from a rather relaxed community where people could talk to a hyper political fighting arena where you can only be a right/left wing shill.

The ban-hammer heavy moderation doesn't really help. I would post this criticism on the subreddit itself, but it would be removed as any criticism of the sub/mods is against the rules and is automatically caught by the AutoMod.

The sub seems to really be in favor of progressive skeptical thinking but the manner in which the mods operate the subreddit is exactly the opposite.
Yep! To be fair, Google software is usually technically very good (e.g. their security is second to none), but they have no product vision, and often very bad UX/DX.
I understand your frustration, but it seems clear to me that there is difference in what you consider high level technical skills, and what others might perceive as such.

In a highly paid position, both selling yourself and your ideas, and smoothing out differences such as this one, are expected from the employee.

While I believe that with your experience, you have accomplished a high degree of strong delivery... You still need to be able to manage this whole dealing with people thing. Because that’s why you get paid a high salary, to get any issues out of the way in a skilled manner.

> I am scared. Really scared. Everyone should be.

This is a statement about your mental health, not one about reality. Barring a badly-timed war, the global standard of living in 2100 will be much better than today’s. Even if global warming causes 10% less increase in GDP, as some modeling conservatively predicts.

If you want something to freak out about, I’d recommend nuclear war, the next AIDS-like virus, drone terrorism, and the casual destruction of human prosperity caused by housing policies.
> There were forecasts of doom, so we did something about it, so then there was no doom. That doesn't mean the original alarm bells weren't justified.

The field hospitals were built at roughly the same time the lockdowns started. You seem to be saying the decision to build them should be made independently of doing anything else.

But I generally agree with your sentiment about hindsight and acting conservatively. Though that includes knowing what the conservative option even is. Do we also burn money and spray disinfectant on the streets? Are we manufacturing a recession for nothing?
Ask HN: Why we shouldn’t care about Intel ME?
Today, there are many real threats:

- Terrorism

- Russian hackers

- Culture war breaking up the slowly evolved perfect family model based on gender roles (who is against this: feminists)

- Intellecutal property theft by China

The US has superiority in technology (and has for a number of years) because we have the best people, as well as immigration policies to bring in more, based on a real meritocracy.

I read someone write recently: "but Intel can basically root into all computers"

I don't doubt this, and the NSA is in effect the password manager for the world, since they could have access to the world’s newest computers, so what? Somebody has to be that person, why not us?

Alexander Karp who works for the prestigious US defense contractor Palantir (and original Paypal Maffia), has a great view in this interview, where he says democracy must decide: https://www.youtube.com/watch?v=MA0Nxc1DBdU

We have proven to be the country that is most capable of peace, and we donate the most to charity (and have the most generous philanthropists) in the world. Why are people still doubting that we want to do good in the world?

I'm quite interested in these arguments, and I'm keen to see if others have some good arguments they'd like to share. I guess it's a type of 'crowdsourcing' of arguments - if you will.

Thank you for reading kind sirs.

[Please keep the discussion civil. I have made a throwaway account because somehow people think this arbitrary position is political and I've been attacked before, when actually my positionss are just common sense, and builds on what has worked in our evolution as homo sapiens so far. Should we really just throw away progress?]
> Have any of their “predictions” aged well?

No, but only in the sense that they've tended to be too conservative and to understate the degree and pace of change.

And just to be clear, the paper linked to is a review of weather station data which finds that extreme heat & humidity conditions are occurring sooner and more frequently than models predicted.

I’m in the UK and we often have the same problem (a month or two in the summer of unbearable heat) but most companies refuse to spend just for those one/two months.
That's rally not correct. Interpretation of the double-slit experiment relies on the electron (or photon) wave actually spanning both slits. It's not enough to treat the electron as a point particle and the wave as being something we pretend exists to explain it's wave-like behaviour. If the wave wasn't real, we wouldn't see the behaviour.
Remember simcity's microwave power station? Microwaves beamed down from space :)

The problem is that this whole dealing with people thing isn’t solely dependent on yourself, the people you are dealing with need to go along.
I've never failed a take-home test (out of 7) and I do it by doing things no reasonable person would do for production code.
I will write a comment for every line (within reason). I will write an entire page of documentation for a one hour project. I will write a test to check for the presence of a title in the rendered page. I will make sure to host it on AWS or Azure and give them instructions on how to upload it themselves (even if any dev should know how to throw a git repo onto the cloud).

They seem to just be looking that you can do things to a certain level of excellence (even if practically unreasonable).

The most recent take-home test was one hour of code and two hours of window dressing. Totally absurd, but I keep doing fine on that step.

EDIT: If you are talking about the Hackerranks, those are frustrating simply because you can't clarify requirements. I remember back in university that we gathered in groups to do them to just cover as many test cases as a team as possible.
Doesn't help with multiple windows of the same app, I'd guess?

fzf.

Anywhere you want to find something, but particularly find something and do something with or to it, aliases or small scripts or plugins using fzf are great.

No specifics because I think it's a great Unix-spirited 'one thing well' and it's better to implement what works for you around it yourself, but I use it in: vim (filenames, file by contents, buffer names), password management, several git aliases for running commands with either a fuzzy found SHA or file, and more.

I was going to leave it at fzf, but as a bonus - bat. Use it in fzf previews, to see, with syntax highlighting, what you're selecting before you select it.

Ben Goldacre (and others) have done a rapid assessment of covid-19 risk. https://opensafely.org/outputs/2020/05/covid-risk-factors/

> Results: There were 5683 deaths attributed to COVID-19. In summary after full adjustment, death from COVID-19 was strongly associated with: being male (hazard ratio 1.99, 95%CI 1.88-2.10); older age and deprivation (both with a strong gradient); uncontrolled diabetes (HR 2.36 95% CI 2.18-2.56); severe asthma (HR 1.25 CI 1.08-1.44); and various other prior medical conditions. Compared to people with ethnicity recorded as white, black people were at higher risk of death, with only partial attenuation in hazard ratios from the fully adjusted model (age-sex adjusted HR 2.17 95% CI 1.84-2.57; fully adjusted HR 1.71 95% CI 1.44-2.02); with similar findings for Asian people (age-sex adjusted HR 1.95 95% CI 1.73-2.18; fully adjusted HR 1.62 95% CI 1.43-1.82).

I have a vague memory of a similar parody article which I've never been able to find again. IIRC it was in Ruby and he imported all libraries into a "god" object that could do absolutely anything.

Anyone know what I mean?
It's been the same experience for me. I've been successful as a developer and yet have never encountered many of these problems that interviews in the past demanded I know.

Ultimately if I end up encountering a problem like that in my career, the honest answer is to pick up a book or begin reading through articles on solutions. Sadly that kind of answer seems to be frowned upon because it's better for you to lie about what you know than to admit you don't know the solution and figure out ways to rectify it.
Is the trick that some people think it’s zero or something?
Ah screw it, I'll be the boy in "the emperor's new clothes". Google sucks! They try to put themselves on cloud9 and look at us "mortals" like we should be grateful for 8 interviews, LOL.

A delay would be logical if it provided time to develop a countermeasure. But other than point-defence ABM systems there is no universal countermeasure, practical or in development.

Or implement similar constraints.

I've sometimes wondered what an FPS bot would be like, if it had random noise injected into its aim so that it couldn't just aimbot you; or if it tended to forget where people had been. It could still perfectly strategize about its own limits, but those limits would be unavoidable.

Or an RTS AI with a hard max on APM and some kind of attention span switching delay (like scrolling the map to get to where the action is).
Human society is often imbued with a desision making powers that don't really exist. Why do we xxxx?! (insert damaging human behaviour here) people say, it makes no sense!

It makes intuitive sense to us that "humans" collectivley can and should make rational desisions, because we feel as thought we can do this individually. The reason we extrapolate this from 1 individual to many is because we don't see ourseleves or our society as a natural chaotic system, we see it as a rational desision making system that's broken and we're wrong.

You are wrong. The Outer Space Treaty bans nuclear weapons in space, but e.g. mass drivers shooting tungsten slugs which would have nuclear-like effects aren't banned, nor is anything else.

Even if a treaty did ban these weapons it wouldn't be "illegal" for a major power in any meaningful sense. These mutual arms restriction treaties are only followed by the major power as long as they see a mutual interest in doing so.
