海外TECH	DEV Community	Discussing Bloom Filters	https://dev.to/akarshan96/discussing-bloom-filters-3ee3	Discussing Bloom FiltersLet s start this blog by discussing a few scenarios and analyzing the search algorithms Scenario This is the classic case of the use of Bloom Filter For instance you are creating a new username for Instagram and suddenly it flashes this username is already being taken up This happens in a fraction of a second But give it a thought how it can read millions of record in the database to search for the name in such a short time The first thought pops up is using search algorithms But the linear search is not efficient enough to pull the results from the database that fast On the other hand Binary search comes with a restriction that all the user records are stored alphabetically and also not accurate when dealing with words So Instagram must be using Bloom Filter to achieve this Scenario Social media sites generate so much content each second and one of it s most awesome feature is of it is that we generally don t see the same content posts stories etc again and again This means these sites maintain a record of the content that is already viewed by the user Now let s wonder the ways they can achieve this One is to store the content accessed by the user in the database and continuously query it to check if the content is visited by the user before This is not both time and space efficient since the application needs to maintain a huge amount of data per user and also iterate through it To make the process more efficient Bloom Filter is maintained for each user Both Medium and Quora use this to solve the above problem We discussed the scenarios where we can overcome space and time complexities with the help Bloom Filters Now let s understand what is Bloom Filter Explaining Bloom FilterBloom Filter is a probabilistic data structure By probabilistic it means this data structure can the likelihood of an element in a set Bloom Filter generates False Positive results which mean it tells if an element is not in a set but isn t sure about if it in the set It tells either possibly in the set or definitely not in set Let s demystify it a little bit Bloom Filter is a bit array of fixed length The value of a bit either can be or This bit array is initialized with all bits set to When an element needs to be added it is passed through a no of hash functions and the result of each hash function becomes indices of bit array which are then set to Let s say we have a bit array of length Let s say we are using hash functions h and h We receive strings apple and orange Suppose h apple h apple So we will set rd and th index in array as For string orange supposeh orange h orange Looking at the current array we can see nd and th are means no orange string never received otherwise the bit at those index would be Let s take another example We receive pear string and suppose h pear h pear So hash function h for orange already set bit at index as But still since we also get index which currently it means we didn t ever receive or stored pear before Now if we get apple again h apple and h apple Since both of these index already set as we do know it already exists in the set There might be a chance where we get a string even doesn t exist in the set or the storage have indexes received from hash functions as in the bit array We can certainly reduce the probability of the collisions by increasing no of hash functionincreasing length of bit arrayboth and This totally depends the frequency of data we receive for which we have to implement bloom filter If we need to calculate the size of bit array or the size of bit array based on data we receive we can do using following formulasm n lnP ln k m n lnwhere m is size of bit array n is expected number of elements P is desired false positive probability k is no of hash functions	2021-07-22 17:26:52

海外TECH	Engadget	Panic's Playdate handheld isn't for everyone, and that's OK	https://www.engadget.com/playdate-preview-170047433.html?src=rss	Panic x s Playdate handheld isn x t for everyone and that x s OKNearly two years after the Playdate made its public debut Panic s quirky gaming handheld with a crank is ready for the masses The company recently announced that the Playdate will be available for pre order on July th for with a ship date of later this year I ve been playing with a “press preview version of the Playdate for the past couple of weeks and while it s not perfect I still think it s an incredibly charming handheld with a lot of potential The question is whether there ll be enough interest ーfrom both developers and consumers ーto keep it going for the long haul For the uninitiated the Playdate is not just Panic s first ever gaming handheld it s also the company s first piece of hardware period Panic made its name making Mac software like Transmit and Coda and has recently ventured into publishing indie games such as Firewatch Untitled Goose Game and the yet to be released Nour Play With Your Food From its inception Panic wanted Playdate to be a different kind of handheld instead of something mainstream like Nintendo s Switch it was supposed to be more like the Game amp Watch devices of yore but with a modern twist “We didn t want it to be too cool but we didn t want it to be too goofy said Cabel Sasser Panic s co founder Thanks to a design collaboration with Teenage Engineering known mostly for making quirky audio gear the Playdate certainly fulfills that brief The hardware is tiny about the size of a stack of Post It notes x x mm and has a black and white screen But its most unique design feature is its fold out crank which acts as an additional game controller It s this combination of silly and adorable that adds to the Playdate s charm and I ll fully admit that I fell for it the first time I tried a prototype back in EngadgetThe aforementioned preview unit I have on hand is the final hardware though the software isn t quite there yet Everything is similar to how it was two years ago The button placement is the same with the D pad and A and B buttons under the display the menu button on the right and the lock button sitting on the top you activate the Playdate by pressing the lock button twice pressing it again will enable standby mode All the controls feel responsive enough with a pleasant clickiness On the side is the mono speaker which is surprisingly loud and clear given its size Underneath is a mm headphone jack plus a USB C charging port Most important to me however was that crank which is housed on the Playdate s right side To access it simply flip it open to reveal a small rotating yellow handle which you can then use to rotate the arm backwards or forwards The whole contraption feels a lot more solid than I remember the rotation feels silky smooth but it isn t so loose that it continues to spin when I let go This is a good thing as it allows for more precise control which turns out to be quite important in certain games Internally the Playdate has a MHz Cortex M CPU MB of RAM GB of Flash storage Bluetooth and bgn GHz Wi Fi The Playdate is molded from what Panic says is an extremely durable engineering thermoplastic and the screen is laminated to a hardened glass face That aforementioned crank is also pretty solid it s made out of stainless steel and the handle is plastic with a stainless steel core The Playdate will likely survive the occasional jostle in your pocket or bag But if you want to keep it completely free of blemishes Panic does offer a cover for You could also purchase the Playdate bundled with the cover for EngadgetWhile I do like the hardware for the most part I have to admit I have a somewhat love hate relationship with the screen One of the reasons Panic chose to go with a Sharp Memory LCD was because of its super sharp pixels that use very little power Pebble aficionados might recall that its eponymous smartwatch used Sharp Memory LCDs as well I agree that the black and white images do look very crisp especially in bright sunlight However the Playdate lacks any kind of backlight or front light which means it s terrible in dim environments Maybe it s because I live and work in a relatively dark room but I found this rather annoying At one point I had to position a book light underneath the Playdate just to play a game on the couch I should note that the Playdate does last a long time in between charges I ve left it unplugged for nearly two weeks now and even though I ve played a few hours every day it still has over half of its battery life left I also noticed an “Upside Down mode in the Settings menu which turns the screen well upside down When asked Sasser said that this is an experimental mode for left handed users who want to use the crank with their left hands He did say however that this is feature is still subject to change As wonderful as the hardware is the real value of the Playdate is the content Though the device costs it will now come with different titles instead of the initial it ll also ship with GB of storage instead of My preview unit only came with four games however Crankin s Time Travel Adventure Lost Your Marbles Saturday Edition and Whitewater Wipeout EngadgetI had already played Crankin a couple of years ago when I tried the Playdate for the first time Designed by Katamari Damacy s Keita Takahashi the only controller in this game is the crank which you ll use to hurry Crankin along his path to meet his girlfriend Crankette Spinning it forward will move him forward while spinning it backward will get Crankin to do the same The trick is that you have to navigate various obstacles like bees and birds which exist outside the flow of time So as you rush along you have to position Crankin in such a way that he can avoid them For example you ll want Crankin to bend down to smell the flowers exactly when the bees fly overhead That might seem like a relatively easy premise but the obstacles get more complicated as the levels progress forcing me to replay them several times before I can get them right Currently I m stuck on level five despite multiple attempts Guess I m not going to see Crankette any time soon I much prefer Lost Your Marbles which was designed by Sweet Baby Inc amp Friends In this game a girl named Prota is going to work for a cat scientist named Marbels no that s not a typo but unwittingly brings her dog Minty along on her first day Let s just say that things don t go well and Minty eventually goes missing Somehow Prota also uh loses her “marbles in the process As Prota goes around town trying to find her dog you answer questions by using the crank to roll a marble around an obstacle filled construction making sure that the marble hits the answer you want It s not explicitly said but my guess is that the marble puzzle here represents Prota s brain EngadgetI found it a little tricky to control the marble so I ended up picking a lot of what I thought were incorrect answers But I soon found out that there s really no such thing as the wrong answer in this game That s because the weirder the answer the more hilarious the story becomes For example when you re picking the photo for Minty s missing dog poster one of the options is for her butt I didn t mean to select it but I did so accidentally I know this all sounds incredibly silly and it is but I also found the whole thing very amusing Saturday Edition on the other hand is a lot more serious at least on the surface Developed by Chris Makris this is a point and click style adventure game which doesn t use the crank at all Instead all navigation is done via the D pad and A and B buttons In this game you play the character of John Kornfield who s had a long history with aliens but is currently on Earth The game opens with him in his apartment and the cops are knocking on the door Using the controls you re able to interact with various elements in the apartment like listening to the answering machine or opening the microwave The game suggested to me that it s a lot wiser to exit the apartment via the fire escape instead so I did I ll admit that I haven t gotten very far in this game ーI ve so far only been to his office and the nearby shopping mall I do find the story quite intriguing so far but I m going to have to sink in a few more hours before I uncover all the game s secrets EngadgetLast but not least is Whitewater Wipeout by Chuhai Labs All you have to do here is surf for as long as possible performing tricks along the way to earn points Like Crankin the only controller here is the crank which you ll use to move the surfboard The highest score I ve achieved so far is which is not great at all There will eventually be a global leaderboard which you can use to compare your skills to others If it isn t obvious by now my favorite games are the ones with a heavy story element such as Lost Your Marbles and Saturday Edition I am not very good with hand eye coordination so Crankin and Wipeout are not really my thing I ll also add that after a week or so of playing the same four games over and over I got bored pretty quickly Thankfully however the Playdate will definitely be getting more games As part of its price the console actually comes bundled with a season s worth of titles ー games in total The first two games will start downloading the moment you activate your Playdate and then you ll get two games every Monday thereafter for weeks That is fundamentally the sticking point with any console like this ーas quirky and glorious as the hardware is it ll live and die in the amount of new games you can add to this on a regular basis The indie gaming community has already embraced the Playdate wholeheartedly ーtens of thousands of developers have already expressed interest in making games for it ーand the company announced that they ll be able to sell software and games that can be sideloaded to the device There s no denying that the Playdate is a fairly niche device ーit s an indie handheld made for indie games ーand that s the very thing that is so appealing about it But it s unclear if interest in the Playdate will last beyond its initial release	2021-07-22 17:00:47
