> I'd like to believe that's true, but I've spent quite a lot of time trying to explain pointers and recursion to people and either they get it right away or practically never.

Have you thought about may be you don't understand pointers and just think you do ? May be you should not start teaching and explaining about pointers before you understand it well. If you can't pin-point why your students don't understand and just say they won't understand at all (may be weak math background or something else), then I'm sorry you lack the knowledge to teach or use pointers.

Your reference to Joel and how you rely so much on your intuition tells me that you tend to have "I'm better than other" type of feeling just because you understand DP. This is the exact toxic I would want to avoid in the workplace. Same with Joel's reference, I'm shocked that he thinks understanding pointers is not a skill (may be I should interview him on pointer arithmetic and see just how good he is). My experience has been that these interviewers who say they are so good in DP, pointers, recursion and throw this aura of 'false negative' and know it all show true colors after the interview. They make wrong decisions on when to optimize, are clueless about scale and distributed systems, can't write complex sql, just don't know how to turn on little knobs to solve the problem so write huge unnecessary code. All this is probably because they never thought more than DP/recursion (which I would avoid at any cost in my code base).

Q. Can the users completely delete their data ?

Zuckerberg: Yes, there are two options. First to deactivate because students and want to suspend and come back because they want to study for exam. Second option is users can totally delete all their data.

Where is the second option anyone from Facebook ? There is only an option to delete the account after you DIE, not an option to delete it when you are alive.

So many lies.

How do you hire engineers who are bad at interviewing?

zippy786 — Tue, 14 Mar 2017 05:06:02 +0000

How do you identify engineers who are extremly good when they work with headphones on in a semi-alone environment but bad at interviewing because they are surrounded by people watching them code and trying to get into their brains ?

Whiteboards are bad for writing programs. Think about how often you write programs on whiteboard, it's mostly for diagrams and system flow not to write for and while loops for hard problems. My thinking pattern is different when I write program I tend to write the skeleton first and then fill it out. Writing on whiteboard although I know the solution I'm just spending time writing which sucks (may be because the only thing I write is a cheque once a month and I'm not used to writing for years). Now if it were typing, within the same span of time I can write two or three programs find mistakes and solve everything. Hence I find coding on computer much better than whiteboard and these days I refuse interviewing on whiteboards and say so to anyone who wants to hire me.

Edit: It's ironic how the so called cutting-edge tech companies can't afford a keyboard, mouse, laptop and a projector which would make things way better. I even had a case where the interviewer changed the question with 5 min. to spare , I explained the solution he said it would work and then told me to write it. I was just erasing and pointing arrows because I did not have space etc. So easy to forget that while typing you just hit enter and get a new line. Draw on white board, write on computer; that's how it should be.

Why are so many companies using Node.js?

zippy786 — Thu, 02 Mar 2017 05:33:53 +0000

I've seen it being used in quite a number of places now (specially startups) and I don't get why people use it over other stacks which might be easier to maintain and code. Here are couple of things that comes to mind

- Most startups have inexperienced people writing async code (which is hard) and make too many mistakes

- The reason Javascript is used in frontend let's use it for backend (even using the same programmer) seems flawed. Backend programming would require intimate knowledge of threads, mutexes, async and other things which a frontend programmer may not be familiar with so using the same programmer or language may be moot.

- Flaky drivers. Surely it works great with MongoDB but try using MariaDB, Postgres with concurrency and pooling and there are so many issues (async is hard ?).

- Is Node.js performance really that good when people start making mistakes and bugs arise that infact hinders performance. Why people move to Node.js when horizontal scaling can provide sufficient performance needed by most.

These are only couple of points, may be Hackernews can give more perspective towards why some of the people/companies choose Node.js with these flaws. Is it because it's new or the love of Javascript (designed in less than 1 month) is so much that it has bleed into the backend realm.

zippy786 — Fri, 27 Jan 2017 07:20:27 +0000

I think you will be wasting your money and setting up a bad culture. How many rounds of review are you going to ? After the first round will you hire another one to do more rounds ? Although the product works, it seems you seem to want 100% bullet proof product which will not be possible. Just make sure your product works and when you start making money hire a team and not freelancers to do your code review and manage the product.

I am wondering how many of you work part-time 10-20 hr freelancing or building other's MVP while still having a full-time job. Did you have to sign any agreement to the full-time employer for this ?

Job post is a marketing gig for them. I don't think they go through the resume or hire anyone, just keep posting the same jobs over several months.
