海外TECH	DEV Community	Advent of Code #3 (in JavaScript & Haskell)	https://dev.to/sethcalebweeks/advent-of-code-3-in-javascript-haskell-52m1	Advent of Code in JavaScript amp Haskell Today s Advent of Code problem is a tough one On the surface it looks very similar to day one and two but there is a lot more going on While I was able to solve day one and two fairly quickly in Excel I had to jump straight to Haskell and JavaScript to find today s solutions Part I won t reiterate the problem because it is pretty complicated Our input is an array of binary strings input The first order of business is to turn each binary string into a list of integers I had to split this into two steps because I was fighting with the Haskell type system charArrays Char charArrays map map inputbitArrays Int bitArrays map map read Char gt Int charArraysThen we zip together all the bitArrays to get the total number of ones in each bit position I m using foldl so that the first value of the input list is used as the initial value bitCounts Int bitCounts foldl zipWith bitArraysNext we check whether one or zero occurs more frequently for each bit by comparing the count to half of the total input length The least common is simply the bit reversal of the most common mostCommon Int mostCommon map number gt if number gt length input div then else bitCountsleastCommon Int leastCommon map number gt if number then else mostCommonTo convert the bitArrays into decimal numbers we reverse the list to start from the right side and fold keeping track of the power and accumulated total The power is multiplied by two each iteration and the current bit multiplied by the current power is added to the accumulator I tried to figure out how to use foldr instead of foldl but couldn t get it working toDecimal Int gt InttoDecimal fst foldl acc power x gt acc power x power reverseThe finally answer is the most and least common numbers multiplied together gamma Intgamma toDecimal mostCommonepsilon Int epsilon toDecimal leastCommonanswer gamma epsilonIn JavaScript we can convert the input into bit arrays in one shot pretty easily const bitArrays input map binary gt binary split map char gt parseInt char We need to define our own zipWith function prior to reducing to find the totals of each bit position The reduce function in JavaScript automatically uses the first element if no initial value is provided const zipWith f a b gt Array Math min a length b length fill map i gt f a i b i const bitCounts bitArrays reduce acc x gt zipWith a b gt a b acc x The rest of the solution is very similar to the Haskell implementation const mostCommon bitCounts map total gt total gt input length const leastCommon mostCommon map total gt total const toDecimal bitArray gt bitArray reverse reduce acc power x gt acc power x power const gamma toDecimal mostCommon const epsilon toDecimal leastCommon const answer gamma epsilon Part This part looks similar to the first one but is drastically different We start off by creating a helper function which will split a list of bitArrays into two lists depending on whether a given bit is zero or one In general this is just a filter function which also returns the values that were rejected from the filter criteria You can tell we are in wacky land when we pull out array indexing using the operator splitByBit Int gt Int gt Int Int splitByBit bit foldl ones zeros x gt if x bit then x ones zeros else ones x zeros Using this helper function we need a recursive function to test out each bit position until we get a single result back for the oxygen generator and CO scrubber ratings Technically there are situations that are not handled by these functions but they work according to the problem description oxygenGenerator Int gt Int gt IntoxygenGenerator bit bitArrays length ones gt length zeros if length ones then toDecimal head ones else oxygenGenerator bit ones otherwise if length zeros then toDecimal head zeros else oxygenGenerator bit zeros where ones zeros splitByBit bit bitArrayscoScrubber Int gt Int gt IntcoScrubber bit bitArrays length zeros lt length ones if length zeros then toDecimal head zeros else coScrubber bit zeros otherwise if length ones then toDecimal head ones else coScrubber bit ones where ones zeros splitByBit bit bitArraysAnd finally we call our recursive functions with initial conditions to get the final results oxygenGeneratorRating IntoxygenGeneratorRating oxygenGenerator bitArrayscoScrubberRating IntcoScrubberRating coScrubber bitArraysanswer oxygenGeneratorRating coScrubberRatingAgain this translates relatively easily into JavaScript so here is the whole thing minus the stuff we already defined in part const splitByBit bit array gt array reduce ones zeros x gt x bit x ones zeros ones x zeros const oxygenGenerator bit bitArrays gt ones zeros splitByBit bit bitArrays if ones length gt zeros length return ones length toDecimal ones oxygenGeneratorRating bit

toDecimal zeros coScrubberRating bit zeros return ones length toDecimal ones coScrubberRating bit ones const oxygenGeneratorRating oxygenGenerator bitArrays const coScrubberRating coScrubber bitArrays const answer oxygenGeneratorRating coScrubberRating The biggest struggle I had with this problem was messing with the Haskell types and figuring out the deeply nested conditional logic I think the conditional logic could be further improved in Haskell through some smart pattern matching	2021-12-04 05:45:15

海外TECH	DEV Community	Reviving an Old Feature Request in Telescope	https://dev.to/belokond/reviving-an-old-feature-request-in-telescope-of2	Reviving an Old Feature Request in TelescopeFor a while now I was looking for an issue to work on for my release assignment The issue I found is huge but very interesting The expectations for this release are very high so I was looking for something challenging enough to meet them After searching for several days I finally found one ❁´ ❁ The feature request is in Telescope the blog aggregator for Seneca students The Feature An integration with LivestreamsThe whole feature request or at least the idea about it can be found in the original issue and also you can read David Humphrey s blog post about the idea and what sparked it I have to admit that I will not work on the whole feature as it is related to a lot of new parts that would have to be thoroughly researched tested reviewed and approved and I don t want to overwhelm myself or the team to review my PR The part I will work on for my release will be introducing video aggregation in Telescope Action Plan for Video AggregationI am not very familiar with video aggregation as I only heard about blog aggregation when I first learned about Telescope so I am completely clueless on how it might work To begin with I plan to aggregate videos from YouTube as it is the biggest video platform in the world and YouTube has a really useful Data API that fits my use case Some More PlanningAs I mentioned before my plan for video aggregation is going to be based off of what I know from Telescope I have read the source code of Telescope and I got a general idea and structure of how it works I believe I can do something similar to what we have except with major differences First I would like to explain how Telescope works in a very general overview The Internals of Telescope First off I got a quick diagram of how Telescope can be represented As I have noted from reading the codebase for a few hours the general idea is that the front end communicates with the Microservices API which communicates with the back end The back end is in charge of all the data and blog caching The back end receives a list of feeds to read posts from These blog posts are then cached in the redis database which is read by the Microservices API Of course the back end does more than just caching the blog posts such as indexing the blog posts for searching purposes The front end will access the information from the Redis database through the Microservices API Information such as blog posts users and search are provided by this API So what s the plan Well my basic plan is basically replicating the same ideas as what Telescope provides but with video links to YouTube Since one video at the highest quality takes much more space than hundreds of text blog posts we cannot cache them It will be extremely expensive for us As for the user serving a video at the highest quality is going to eat up the bandwidth like crazy So instead of caching the videos themselves we would cache the video IDs for these videos and then simply embedding a YouTube video player on the front end I have summarized my course of action as the following In the back end portion get a source to retrieve the youtube channels these one may have to be provided by the users in Telescope cache the video ID s of the most recent videos of each one of the channelsIn the API add an endpoint to provide the video ID s or the youtube linksIn the front end portion provide the embedded youtube videos on the timeline where the blog posts are provided ExpectationsMy major expectation out of all of this is that the feature gets resurrected so that it can be carried to completion I also expect to complete the back end part of the plan in a few days as I think it will form a strong base on what we actually need to show in the front end This is probably going to be my biggest PR yet in open source as it will have to include documentation and tests for all of this ‍‍Either way wish me the best on this challenge	2021-12-04 05:17:53
