qntm posted:then higher-than-normal is the new normal, pick a server at random it's the new normal for the app server in question, but if it's just a network problem on that app server, failing out and letting the load balancer move traffic to another app server would be a better choice same if it's a problem with the db cluster: failing out and letting the dns load balancer move traffic to another datacenter is probably better than having high error rates but if you only have the one cluster, don't just fail hard it's not a black-and-white issue, and it's an interview question with no good answer, just an open-ended discussion about tradeoffs

a guy asks for a algorithm book and cormen doesn't even get brought up? also, I got asked this question at two different shops: Find the intersection between two strings (in C). What is its runtime? If I gave an O(n) solution, they would ask me to give a O(n^2) solution, if I gave an O(n^2) solution they asked me to do it in O(n). hth

ah yes, that was a bit vague it was find the set of characters found in string 1 and in string 2. return it! (exclamation was my emphasis)

so i want to write some sort of image filter thing to make images look like the original gameboy screen which had a weird 2 bit monochrome swamp green display the trouble being i#ve no idea how to start going about this like, i think i can convert an image to 2 bit monochrome easy enough its just the weird green colour thats im not sure about also the gameboy has small gaps between its pixels i dont even know how to go about doing, a graphics shader maybe?

Malcolm XML posted:is this for set or multiset instersection tho does it make a difference? a) use a hash, keep count of how many elements are in a set. find the intersection of hash keys + sum of hash values (or same but use array with counts) b) if mutiset is expressed as sorted string, merge them, skipping ones that only appear in one string, keeping duplicates c) two for loops

Awia posted:so i want to write some sort of image filter thing to make images look like the original gameboy screen which had a weird 2 bit monochrome swamp green display for 2 bit monochrome, you want to threshold on pixel color. for spacing, you probably first want to down sample the image then set like every nth row and column of pixels to off, or you could space everything out.

Awia posted:so i want to write some sort of image filter thing to make images look like the original gameboy screen which had a weird 2 bit monochrome swamp green display Downsample the original image, then convert to 2 bit monochrome. Then convert back to 32-bit color, using appropriate green values instead of just 4 shades of gray. Then stretch the image back out to the desired final resolution using nearest neighbor filtering, and insert a pixel or two of empty space between the fake LCD pixels.

pointsofdata posted:how big can a java class get before it should start setting off warning bells? size/lines of code is a pretty good metric for software complexity, but not reliability, or correctness[1]. unfortunately, sometimes things have to be a bit long, or a bit complex, to capture the problem and manage the details. it's much easier to talk about good style and bad smells, instead of short and long code. - a class with lots and lots of internal state is a good alarm bell - a class with more than 10 methods can be bad, but sometimes you have methods for sugar. - a class that has lots of subclasses might be ok, but sometimes it's good to move them out into their own files too. the thing is, the longer the code is, you're more likely to see these things.

I'm in Canadan and I have a super good offer for a position, but I need an enhanced reliability clearance (which is not hard to get but my boss will be contacted as part of it). Do I tell him that I'm jumping ship or do I lie and tell him that I'm going to do contract work on the side or what help
