An application developer spending hours refining a method/class/function to it's most optimized form is usually not worth the time. It's only going to be used in the application so the ROI is much lower. The author of a

The sweet spot for columnar storage is calculating aggregations across a subset of columns. It can be really fast at that. But if you what you need is select * it might actually be slower in that case.

Crashing early is better than crashing later because it limits the damage and moderately frequent crashes creates some level of caution in the market. Propping up a market because it's too big to fail can in some cases create worse fal

Like many of the other comments here you don't have to quit to sell. But you likely need to pre-announce. Usually the broker where your options are held knows how to set these up. You can mostly choose any sell strategy you want. I onc

I do this two, but I have sort of two mental categories. The people who only occasionally pull me in. I just mute or block then unblock. Then there are the people who consistently try to pull me in and view it as their duty to do so. Those

Threads that are full of flamewars, name calling, and outrage farming is my personal definition of cesspool. I follow many that hold opinions I don't agree with. As long as the conversation is civil I'm perfectly happy talking. Bu

I don't hate crypto per-se. Nor am I particularly gloating about it. However I hope that the silver lining here is that this will be yet another in my evergrowing list of examples to share when I advise people not to get involved in

The biggest problem with these kinds of job description is that they artificially filter out candidates that don't know it's perfectly okay to not check 100% of the boxes before applying. I've never worked or interviewed anyw

The genesis may have been hearsay but the claim itself is verifiable. Are trains of the size he is describing derailing on a higher frequency? Are train lengths exceeding the safety margins of the yards and equipment? Hearsay can be a valua
