My kids play Minecraft but they are not allowed to join servers with strangers. I set up some servers where they have freedom to do what they want but the only people they are allowed to play with are their friends from school and family.

Good point. Cache locality is another important reason that I should have mentioned. I have not run tests, but it may possibly be the most important reason of them all. In many linked data structures you can mitigate a lot of this problem.

Being burned out is a real condition. And so is depression, chronic pains, tinnitus, and so on. Just because something is hard to ascertain doesn't mean it is not real. But there are various levels to being burned out or depressed. And

When I was burned out I got hired into a large bank (think Citi, Credit Suisse, maybe not necessarily Goldman Sachs which has high standards). They have huge amount of backend. Super slow development filled with people who do not have large

The question is "Can you program"? If the answer is "Yes", then stop watching TV, playing video games and lurking on the internet. Honestly, this will sound heartless, but if you can play video games you can also work. T

You don't get to change the rules of the game while the game is being played. The original problem, as stated by me, was: "You are generating k random 64 bit integers. Each time you generate the integer, you have to insert it in a

If that was on a very old operating system (think MS-DOS?) On new operating systems process address space is pieced together independently from physical space. So you can have contiguous, multi-GB array even if you don't have contiguou

Please, read the question. It stipulates that elements are selected at random. You select k integers at random. Some of them might be inserted faster into linked list, but when you average it over k integers you will still be slower because

I am not sure how awesome it is. It looks like something you can stumble on your own by accident on a whiteboard on an interview and use successfully even if you don't know why it works exactly. Honestly, I always thought it is a commo

Oh yeah, linear search I did a lot to the same consternation of other devs. The issue was the device was so low in memory (2MB of unified NV and flash for code, files and operating memory) that there simply did not exist enough space for a

Well, it actually is kinda worse (or better, depends how you look at it). It is not necessarily +10000, it can also be something like x5000. Because CPUs really, really, really like working short, simple, predictable loops that traverse dat

I actually used this algorithm a decade ago to implement a log-based, transactional database system for an embedded system with very low amount of memory and requirement that all memory be statically allocated. To the frustration of the res

Sure we can. And it is surprisingly easy. Sound waves travel 300m every second. If you can get devices synchronised to 1ms (which isn't very difficult given very easy access to GPS which is orders of magnitude more accurate), you can t

This is an old problem resulting from lack of education. People apply standard deviation without first learning that it only makes sense for data that has standard distribution. Standard deviation is a prediction and characterisation tool.

The problem isn't hierarchy, it is how managers are thinking it gives them power over their subordinates (it does not), that they are better than their team because they have been promoted (they are not), and it is how subordinates are

Of course, and that is the point. How can we pay in proportion to the value a developer is creating if we can't even agree on what is valuable?

by twawaaay 4y ago
Developer productivity specifically and knowledge work in general is extremely hard to measure. Not only that, it is also very subjective. What is valuable to one person might be a liability to another. Just the other day I looked at result

F1 also bans cars that get a lot of downforce by traditional aero elements. For example, there is minimum required clearance between the track surface and any element that is not wheels, which severely limits downforce. Additionally, they h

I believe these should be illegal, just as it is in F1. The basic problem with this concept is that if it ever stops working you are now driving way over the limit (not just a tiny bit) of what the car can handle and are unceremoniously thr

Get couple lawsuits for individual pieces of code used without attribution and pretty much every large company will instantly ban Copilot from their development process.

Hate to break it to you, the terminals of CMOS battery are typically almost directly attached to a number of chips that are thousands of times more fragile than the battery itself. Essentially, you can't fry a CMOS battery with a trans

It is not possible for a CMOS battery to get fried this way and the machine be still able to boot. For a CMOS battery to get "fried" a number of components would have to fail catastrophically. There are typically layers of protect

I think the problem needs to be thought through separately for individuals and for organisations. For individuals -- yes, no-one knows what they are doing. Most people, including successful ones, are too embarrassed or insecure to admit thi
