海外TECH	DEV Community	Javascript Array Filter Method	https://dev.to/smpnjn/javascript-array-filter-method-28hg	Javascript Array Filter MethodThe filter method in Javascript creates a shallow copy of an array filtering it based on a number of conditions It accepts a callback function The array which filter produces will usually be a reduced version of the original array Here is a basic example let myArray ️ let filteredArray myArray filter element gt return element element console log filteredArray As you can see the filter method will allow an element to be in the new filtered array should that element return true It effectively loops through each element and runs a test on it to see what should be left Since arrow functions return true implicitly on a single line you might see a more reduced version of this code written like this let myArray ️ let filteredArray myArray filter element gt element element console log filteredArray The filter method callback functionAs mentioned filter accepts a callback function The callback function consists of arguments Array filter element index array gt Filter the array Let s look at what each of these do elementThis is the current element being examined by filter filter goes through each item in the array to test if it should exist in the new filtered array indexThis is the zero based index of the array item we are working with For example if we were viewing the first element in the array this would be arrayThis is the entire array should you wish to do something with the original array Mutating arrays within the filter methodSince filter uses a callback function it is possible to mutate the original array we are examining For example we could push new items to the array each time we filter over an item let myArray ️ let filteredArray myArray filter element gt myArray push ️ return true console log filteredArray ️ As you might have already realised this would produce an infinite loop Fortunately much like in reduce Javascript does not allow this to happen instead any new elements to an array added in this way are ignored However mutation of existing elements is totally fine let myArray ️ let filteredArray myArray filter element index gt myArray index ️ return element ️ console log filteredArray ️ ️ ️ ️ Filtering Arrays of ObjectsFiltering arrays of objects follows the same conventions as with arrays We can filter upon child properties of objects within an array by using the notation For example if I wanted to filter the following array by age where age should be gt I would do something like this let myArray age age age age let filteredArray myArray filter element index gt return element age gt console log filteredArray age age Filtering Arrays by Search CriteriaA common use for filter is to take an array of values and search through them based on a search term This can be done with includes or regex For example let myArray cat catdog dog fish fishcat let filteredArray myArray filter element index gt return element match cat console log filteredArray cat catdog fishcat Filter makes a Shallow Copy of ArraysAlthough it may appear that filter makes a new copy of the original array this is not the case In fact filter makes a shallow copy of the original array which means that if we mutate objects within the array the original will change too To understand this let s look at our age example again let myArray age age age age let filteredArray myArray filter element index gt return element age gt console log filteredArray age age filteredArray age filteredArray age console log filteredArray age age console log myArray age age age age As you can see modifying the filtered array using the filteredArray age notation also modifies the original but wait filteredArray age changes only the filtered array That s because although Javascript interprets the notation as updating both arrays it interprets the square bracket notation as setting a new value at the second position of the filtered array This is just another quirk of Javascript which can be confusing but is very useful to know ConclusionThe filter method is widely used and an easy way to change create new subsets of arrays based on certain criteria It should be noted that only a shallow copy is made of the original array so modifying the array in certain ways will affect the original	2022-10-17 20:40:10
海外TECH	DEV Community	Bitcoin Signatures From Scratch (4/4): ECDSA Implementation in Python Using Zero Dependencies	https://dev.to/exemak/bitcoin-signatures-from-scratch-44-ecdsa-implementation-in-python-using-zero-dependencies-410c	Bitcoin Signatures From Scratch ECDSA Implementation in Python Using Zero DependenciesThe series consists of four parts each part uses the concepts discovered in the previous parts The Magic of Elliptic CurvesThe Magic of Elliptic Curves Combined with Finite FieldsUsing The Magic of Elliptic Curves to Sign and Verify MessagesECDSA Implementation in Python Using Zero Dependencies you re here The bottlenecks We need to be able to perform basic arithmetical operations on very large numbers In programming we can easily operate on large numbers using bignum arithmetic Just google it and you will find out how easy it is So our programming language must support it or we should use some external package to work with it In the examples of this part I will use Python which supports bignum arithmetic out of the box For the Live Demo I will use JavaScript and there we will need the BigNumber js package The other bottleneck that we will encounter is finding the multiplicative inverse of a very large number Obviously brute force is not going to work The multiplicative inverse can be found by the Extended Euclidean algorithm which has the complexity of O log n Python can do it out of the box with its built in pow function def find inverse number modulus return pow number modulus If you need the actual implementation of the algorithm check my Live Demo Let s start writing our code We need one simple thing related to the elliptic curve Point Let s define a class Point In its constructor we should make check whether the point lies on the curve class Point def init self x y curve config a curve config a b curve config b p curve config p if y p x a x b p raise Exception The point is not on the curve self x x self y y self curve config curve configWe need to be able to compare two points add them together and multiply them by an integer Let s add a method to check if two points are equal def is equal to self point return self x point x amp self y point yNow let s implement add method which returns a new Point as the result of addition def add self point p self curve config p if self is equal to point slope point x find inverse point y p p else slope point y self y find inverse point x self x p p x slope point x self x p y slope self x x self y p return Point x y self curve config All the formulas are listed in Part Now let s implement the multiply method The most straightforward implementation would be this def multiply self times point self for i in range times point point add self return pointBut let s say we need to multiply our point by a big number Even if we had the speed of billion additions per second this would take years to calculate this point And this is not even a big number for us Here is a big number Calculating the point in this way would take billions of billions of billions of billions…of years We can define that the efficiency of this algorithm above is O n which is of no use for our purposes If you remember there is an easy way to achieve O log n complexity by continuously doubling our point P P PP P PP P PP P PP P PP P PAnd so log log So we don t need billions of billions of billions…of years We just need operations to get to this large point Just one moment to efficiently multiply by values that are not a degree of it s reasonable to store all the previous values and then combine the results together For example if we need to get P we can no longer double P Neither we can add points one by one potentially this would take billions of billions of years on larger numbers What s reasonable to do instead is P P PP P PSo for that purpose we need to store all the previous P s and afterwards efficiently use them So here is an efficient implementation def multiply self times current point self current coefficient pervious points while current coefficient lt times store current point as a previous point pervious points append current coefficient current point if we can multiply our current point by do it if current coefficient lt times current point current point add current point current coefficient current coefficient if we can t multiply our current point by let s find the biggest previous point to add to our point else next point self next coefficient for previous coefficient previous point in pervious points if previous coefficient current coefficient lt times if previous point x current point x next coefficient previous coefficient next point previous point current point current point add next point current coefficient current coefficient next coefficient return current pointThus we ve got a super efficient implementation And now we can perform all the needed operations on an elliptic curve Let s define secpk secpk curve config a b p x y n g point Point x y secpk curve config I m using only decimal numbers in our examples because they re intuitive for a human So far we ve implemented everything that we discussed in Part Now let s implement the actual digital signature algorithm described in the Part Sign method of ECDSA def sign message message private key k random randint n r point g point multiply k r r point x n if r return sign message message private key k inverse find inverse k n s k inverse message r private key n return r s Verify method of ECDSA def verify signature signature message public key r s signature s inverse find inverse s n u message s inverse n v r s inverse n c point g point multiply u add public key multiply v return c point x rLet s pick some random number as our private key for example Let our message be Do you remember how to get PublicKey from PrivateKey private key any random integerpublic key g point multiply private key message any integerNow let s sign and try to verify signature sign message message private key print Signature signature print Is valid verify signature signature message public key It works You can try to corrupt the signature or the original message and make sure that our algorithm works properly Here is the complete code import randomdef find inverse number modulus return pow number modulus class Point def init self x y curve config a curve config a b curve config b p curve config p if y p x a x b p raise Exception The point is not on the curve self x x self y y self curve config curve config def is equal to self point return self x point x and self y point y def add self point p self curve

we can t multiply our current point by let s find the biggest previous point to add to our point else next point self next coefficient for previous coefficient previous point in pervious points if

integerpublic key g point multiply private key message any integersignature sign message message private key print Signature signature print Is valid verify signature signature message public key So the implementation of the entire ECDSA algorithm took just lines of code And it s perfectly working This is absolutely the same algorithm as the one used in Bitcoin Live DemoAs I promised at the beginning of this article here is the live demo using only the concepts and formulas described in the article Just a couple of notes Initially we could only sign integer messages But in the demo you can choose to apply a hash function sha to your message Thanks to it a message can be a string Bitcoin uses slightly different formats of public keys and signatures Never use it in a production environment It is not safe For production you must only use well tested solutions The end of the seriesI hope this series of articles was very useful for you At least I did my best to make it useful

海外TECH	Engadget	Exclusive: Amazon’s attrition costs $8 billion annually according to leaked documents. And it gets worse.	https://www.engadget.com/amazon-attrition-leadership-ctsmd-201800110.html?src=rss	Exclusive Amazon s attrition costs billion annually according to leaked documents And it gets worse Amazon churns through workers at an astonishing rate well above industry averages According to a tranche of documents marked “Amazon Confidential provided to Engadget and not previously reported on that staggering attrition now has an associated cost “ Worldwide Consumer Field Operations is experiencing high levels of attrition regretted and unregretted across all levels totaling an estimated billion annually for Amazon and its shareholders one of the documents authored earlier this year states For a sense of scale the company s net profit for its fiscal year was billion The documents which include several internal research papers slide decks and spreadsheets paint a bleak picture of Amazon s ability to retain employees and how the current strategy may be financially harmful to the organization as a whole They also broadly condemn Amazon for not adequately using or tracking data in its efforts to train and promote employees an ironic shortcoming for a company which has a reputation for obsessively harvesting consumer information These documents were provided to Engadget by a source who believes these gaps in accounting represent a lack of internal controls “Regretted attrition that is workers choosing to leave the company “occurs twice as often as unregretted attrition people being laid off or fired “across all levels and businesses according to this research The paper published in January of states that the prior year s data “indicates regretted attrition represents a low of to a high of across all levels Tier through Level employees suggesting a distinct retention issue By way of explanation Tier would include entry level roles like the company s thousands of warehouse associates while a vice president would be positioned at Level It also notes that “only one out of three new hires in quot stay with the company for or more days An investigation from the New York Times found that among hourly employees Amazon s turnover was approximately percent annually while work from the Wall Street Journal and National Employment Law Project have both found turnover to be around percent in warehouses ーdouble the industry average The rate at which Amazon has burned through the American working age populus led to another piece of internal research obtained this summer by Recode which cautioned that the company might “deplete the available labor supply in the US in certain metro regions within a few years The assertions contained in this new set of documents align with prior reporting but illustrate that problems with Amazon s workplace and culture extend well above the warehouse floor Managers of every stripe too are butting up against feeling their roles are a dead end “The primary reason exempt leaders are resigning is due to career development and promotions one of the papers states while also indicating those same issues represent the second highest reason for quitting among the non exempt workforce For some leaders this could be because Amazon actively stacks the deck against certain internal promotions The same Times investigation reported the company “intentionally limited upward mobility for hourly workers according to David Niekerk a former Amazon HR Vice President Entry level workers who are able to beat the odds and get ahead are still pitted against the company s preference for fresh college grads Of leaders hired in percent “are university graduates with little to no work nor people leadership experience while only four percent of warehouse process assistants a low level leadership role were promoted to area managers For others though the documents point to considerable issues within Amazon s vast learning and development complex some programs and learning modules of which are overseen by the Consumer Talent Strategy Management and Development CTSMD team CTSMD has existed within Amazon for at least three years according to one report and in that time has ballooned to a headcount of including contractors with a projected million run rate for A slide deck among the documents provided to Engadget states that “most programs under CTSMD s purview were not created and are not currently managed with financial metrics as key metric and that the existing dashboard for reviewing these programs is “inaccurate and obfuscates the actual spend The current arrangement “prevents proper oversight and analysis of CTSMD s current portfolio A report from April of similarly found that CTSMD as of December of last year “did not have a standardized process to measure impact business metrics of our training programs and that the report s authors were “unable to determine whether the learning path had detectable effects on behaviors or business impact including regretted attrition promotion rates or a variety of internal indexing scores Grimly it also notes that CTSMD s definition of “completion for a learning module ー“in contrast to its typical definition in the learning and development industry ーis “simply clicking through to the end of the course Putting this in sharp relief the April report reviewed extant training programs using the Kirkpatrick Model ーa scheme within the learning and development field which evaluates training programs and separates them into four ascending levels Of the programs examined in the report merely asked trainees to react to what they had learned nine measured some level of information recall Only three tracked the degree to which learners were applying any knowledge they gained from the course An additional program ーALM ーsomehow tracked information application but not recall None reached Kirkpatrick level four which measures what impact such training might have on the business Organizational bloat notwithstanding the apparent directionlessness of CTSMD has meaningful financial impacts on Amazon which these documents were willing to estimate Beyond the team s million annual budget Amazon s managers occupying roles from L up to L allegedly spend an estimated average of hours annually on training At what they assess to be an average annual salary of each spread over a deep population of employees one document purports this could represent up to million of potential waste Given again that training is often an integral part of ascending the org structure of Amazon and that lack of meaningful advancement is a major reason for regretted attrition some portion of that billion can likely also be ascribed to CTSMD Another document estimated that even a percent reduction in attrition would save Amazon million annually As previously stated the source who provided these documents to Engadget believes this represents a failure of internal controls “Internal controls are set up so that you have policies and procedures to make sure that the company s strategic mission ーand ultimately their financial statements ーare correct Patricia Wellmeyer an assistant professor of accounting at University of California Irvine s Paul Merage School of Business told Engadget “For these gigantic companies that are listed as large accelerated filers on exchanges here in the US they re required to have elements of good internal control Management is required themselves to go through their own internal control processes and give an opinion on them identify weaknesses and if they re material they definitely have to report them she said Large companies are also required to have an auditor attest to the company s internal controls though according to Professor Wellmeyer so called adverse opinions indicating a lapse in those controls are “quite rare and occur in “probably less than one percent of SEC filings That Amazon had internal reports commissioned on lapses in its training and retention suggests the company is at least aware of the issue It has never disclosed such gaps in its annual K reports its auditor Ernst amp Young has never produced an adverse opinion on Amazon However all such disclosures hinge on the concept of “materiality ーthat is whether it will meaningfully impact the business and its investors Professor Wellermeyer stressed that “there is no bright line rule that I can say Okay anything above this makes this material Those K filings do tell a small story in themselves though A smaller scrappier Amazon of days past included the line “we believe that our future success will depend in part on our continued ability to attract hire and retain qualified personnel for nearly years in its annual filings but seemingly abandoned that belief in its report from onward For the report summarizing Amazon renamed the “employees subsection of its preamble to “human capital ーthe same year it stopped including the phrase “we consider our employee relations to be good While the current slate of learning and development programs appears disorganized and potentially wasteful Amazon is apparently in the midst of streamlining them under a new scheme it s calling Brilliant Basics Another document describing the revamp states that Brilliant Basics was slated to be deployed across operations this past June The pilot module called “employees want to be treated with dignity and respect ーwhich was projected to take to minutes total ーwas tested among a group of leaders in September Only percent completed the module and nearly a quarter never started it A graph which lacks any sort of labeling on its Y axis does not show Brilliant Basics overtaking “existing programs in terms of “learning hours investment until Q of “ A comment on the document notes that like its predecessors there do not appear to be any financial metrics currently associated with Brilliant Basics performance Amazon repeatedly declined to answer specific questions related to these documents Reached for comment a spokesperson wrote “As a company we recognize that it s our employees who contribute daily to our success and that s why we re always evaluating how we re doing and ways we can improve Attrition is something all employers face but we want to do everything we can to make Amazon an employer of choice This is accomplished through offering good pay comprehensive benefits a safe workplace and robust training and educational opportunities that are effective yet always improving Amazon also declined to confirm or deny any of the specific claims or figures made in the documents instead generalizing that internal documents are sometimes “rejected due to lack of reliable data or are modified with corrected information without indicating if that was the case here If you have information to share
