Search - "hash"
I tried finding a gem that would give me a nice, simple diff between two hashes, and also report any missing keys between them. (In an effort to reduce the ridiculous number of update api calls sent out at work.)
I found a few gems that give way too complicated diffs, and they're all several hundred lines long. One of them even writes the diff out in freaking html with colors and everything. it's crazy. Several of the simpler ones don't even support nesting, and another only diffs strings. I found a few possibly-okay choices, but their output is crazy long, and they are none too short, either.
Also, only a few of them support missing keys (since hashes in Ruby return `nil` by default for non-defined keys), which would lead to false negatives.
So... I wrote my own.
It supports diffing anything with anything else, and recurses into anything enumerable. It also supports missing keys/indexes, mixed n-level nesting, missing branches, nil vs "nil" with obvious output, comparing mixed types, empty objects, etc. Returns a simple [a,b] diff array for simple objects, or for nested objects: a flat hash with full paths (like "[key][subkey][sub-subkey]") as top-level keys and the diff arrays as values. Tiny output. Took 36 lines and a little over an hour.
I'm pretty happy with myself. 😁6
3 days 2 nights with only 20 min naps and max 1h of sleep in between. I was finishing my masters thesis. Then I handed it in the next day and everything felt like it is in slow motion? The printing, the going there to hand it in, etc. Couldn't sleep for that day either xD do not recommend. Start writing your thesis on time kids
If i ever see a list of tuples or "key value pair" as a substitute for dictionary or hash map or whatever im going to go crazy18
Here's a fucking challenge:
Generate an MD5 hash in React Native!
crypto - NOPE deprecated, react native throws when you try to import it anyway
react-native-crypto - NOPE, needs to make use of a shim that recursively edits node_modules... hmmmm yeah you think thats a good thing to have?
react-native-fast-crypto - NOPE, no TypeScript types, no documentation in general, only supports sha512?! WTF
garbage fucking idiot tooling stupid dumbass stupid splat splat barf splat22
Currently learning go and I’m really enjoying it. It’s been a while since I learnt a new programming language and the experience is different to what I remember. I’m reading an o reilly book and when about how they implemented a common feature of programming I’m like oh no they didn’t. I think this is what normal feel when they read celebrity gossip. Hash tag goto.2
hey devos, I got a question to ask ya'll. I have an interview tomorrow with an MNC.
I was hovering through some leetcode problems when I came across a hard question that is forcing me to use a hashmap with the key of the user-defined type. I made up my mind to make use of C++ for the coding interview. Now, the problem is C++ asks me to implement a hash function.
If in case, I'm asked a similar question like this in the interview, which of these two options will you suggest:
a) implement your own hash function
b) use pointers as key4
