海外TECH	DEV Community	Investigate GitHub Dependabot patches for npm packages	https://dev.to/stefanalfbo/investigate-github-dependabot-patches-for-npm-packages-n9j	Investigate GitHub Dependabot patches for npm packagesTL DR use Dependabot if you are using GitHub Dependabot alerts can give you a superpower the ability to secure your project by keeping dependency based vulnerabilities out of your code It can be a little bit overwhelming to keep track of all the package dependencies in a TypeScript JavaScript application Lets play with a dummy project to see what we can do mkdir hello cdk amp amp cd hello cdkcdk init app language typescriptNow we will have a package json that looks like this if you have used cdk version name hello cdk version bin hello cdk bin hello cdk js scripts build tsc watch tsc w test jest cdk cdk devDependencies types jest types node jest ts jest aws cdk ts node typescript dependencies aws cdk lib constructs source map support As you can see there are some dependencies added to the project however that is not all the dependencies we have The projects dependencies has their own dependencies and so on and this will create a supply chain of npm packages The command npm ls will print to stdout all the versions of packages that are installed as well as their dependencies when all is specified in a tree structure By running this command we will get a feeling for how many dependencies there are in the project npm ls all wc lThat command gives me packages that s pretty much just by creating a new application If I do the same exercise with npx create react app my app I will get packages This really illustrate the importance of having a tool like Dependabot to help you to keep track of all the dependencies and their vulnerabilities If I add a vulnerable package to the project npm install dash and I use Dependabot then I will get an alert about the vulnerable package directly when this change is pushed to GitHub As you can see there is a lot of information here that is valuable however in this case there is no patch to the problem And every time I push something to the repository I will get a heads up that there are vulnerabilities in the repository Lets add another package npm install lodash now there will even more Depandabot alerts on GitHub This time the alerts has a solution to the problem so it has created a pull request that fixes the problem The message from Dependabot isn t always clear on which dependency in your project that is affected I have stumbled over pull requests from Dependabot that only patches the package that has the vulnerability so the patch is done on the package lock json file For example lets say that this package has got a Dependabot pull request js yaml that will bump the version of it When this happens I like to know which of my applications packages are having a dependency on this package To figure that out you can use npm ls again npm ls js yaml This will give the dependency tree for this package in the project Now I can see that both dash and ts jest has a dependency on this package Perhaps we should update these packages instead The tool for this job is npm check updates However you could also configure Dependabot to create pull requests when there are new versions of a npm package in your application npm install g npm check updatesWith that installed you can use ncu to see what can be upgraded and then upgrade it for you With ncu you can either upgrade all your packages or be more fine grained and just upgrade the packages you want to as you can see from the package usage section upgrade only mochancu mochancu f mochancu filter mocha upgrade packages that start with react ncu react ncu react upgrade everything except nodemonncu nodemonncu x nodemonncu reject nodemon upgrade only chalk mocha and reactncu chalk mocha reactncu chalk mocha reactncu f chalk mocha react upgrade packages that do not start with react ncu react ncu react mac linuxncu react windowsThere is one more npm command I want to mention and that is npm view And it s dependencies Happy npming	2023-08-17 19:25:14
海外TECH	DEV Community	Building an efficient sparse keyword index in Python	https://dev.to/neuml/building-an-efficient-sparse-keyword-index-in-python-27ib	Building an efficient sparse keyword index in PythonSemantic search is a new category of search built on recent advances in Natural Language Processing NLP Traditional search systems use keywords to find data Semantic search has an understanding of natural language and identifies results that have the same meaning not necessarily the same keywords While semantic search adds amazing capabilities sparse keyword indexes can still add value There may be cases where finding an exact match is important or we just want a fast index to quickly do an initial scan of a dataset Unfortunately there aren t a ton of great options for a local Python based keyword index library Most of the options available don t scale and or are highly inefficient designed only for simple situations Given that Python is an interpreted language it often gets a bad rap from a performance standpoint In some cases it s justified as Python can be memory hungry and has a global interpreter lock GIL that forces single thread execution But it is possible to build performant Python on par with other languages This article will explore how to build an efficient sparse keyword index in Python and compare the results with other approaches Install dependenciesInstall txtai and all dependencies Install txtaipip install txtai pytrec eval rank bm elasticsearch Introducing the problemAt a high level keyword indexes work by tokenizing text into lists of tokens per document These tokens are aggregated into frequencies per document and stored in term frequency sparse arrays The term frequency arrays are sparse given that they only store a frequency when the token exists in a document For example if a token exists in of documents the sparse array only has a single entry A dense array stores entries all with zeros except for one One simple approach to store a term frequency sparse array in Python would be having a dictionary of id frequency per token The problem with this approach is that Python has significant object overhead Let s inspect the size used for a single number import sysa sys getsizeof a bytes for a single integer Compared to a native int long which is or bytes this is quite wasteful Imagine having thousands of id frequency mappings Memory usage will grow fast Let s demonstrate The code below runs a self contained Python process that creates a list of million numbers Running as a separate process helps calculate more accurate memory usage stats import psutilresults for x in range int e results append x print f MEMORY USAGE psutil Process memory info rss MB MEMORY USAGE MBApproximately MB of memory is used for this array That seems high Efficient numeric arrays in PythonFortunately Python has a module for building efficient arrays of numeric values This module enables building arrays with the same native type Let s try doing that with a long long type which takes bytes from array import arrayimport psutilresults array q for x in range int e results append x print f MEMORY USAGE psutil Process memory info rss MB MEMORY USAGE MBAs we can see memory usage went from MB to MB That s a x reduction which is in line with the earlier calculate of bytes number vs bytes number Efficient processing of numeric dataLarge computations in pure Python can also be painfully slow Luckily there is a robust landscape of options for numeric processing The most popular framework is NumPy There is also PyTorch and other GPU based tensor processing frameworks Below is a simple example that sorts an array in Python vs NumPy to demonstrate import randomimport timedata random randint for x in range start time time sorted data reverse True print time time start import numpy as npdata np array data start time time np sort data print time time start As we can see sorting an array in NumPy is significantly faster It might not seem like a lot but this adds up when run in bulk Sparse keyword indexes in txtaiNow that we ve discussed the key performance concepts let s talk about how to apply this to building sparse keyword indexes Going back to the original approach for a term frequency sparse array we see that using the Python array package is more efficient In txtai this method is used to build term frequency arrays for each token This results in near native speed and memory usage The search method uses a number of NumPy methods to efficiently calculate query term matches Each query is tokenized and those token term frequency arrays are retrieved to calculate query scores These NumPy methods are all written in C and often drop the GIL So once again near native speed and the ability to use multithreading Read the full implementation on GitHub to learn more Evaluating performanceFirst a review of the landscape As said in the introduction there aren t a ton of good options Apache Lucene is by far the best traditional search index from a speed performance and functionality standpoint It s the base for Elasticsearch OpenSearch and many other projects But it requires Java Here are the options we ll explore Rank BM project the top result when searching for python bm SQLite FTS extension This extension builds a sparse keyword index right in SQLite We ll use the BEIR dataset We ll also use a benchmarks script from the txtai project This benchmarks script has methods to work with the BEIR dataset Couple important caveats on the benchmarks script For the SQLite FTS implementation each token is joined together with an OR clause SQLite FTS implicitly joins clauses together with AND clauses by default By contrast Lucene s default operator is an OR The Elasticsearch implementation uses x as it s simpler to instantiate in a notebook All methods except Elasticsearch use txtai s unicode tokenizer to tokenize text for consistencyimport os Get benchmarks scriptos

headers list the source dataset index method index time s memory usage MB search time s and NDCG MAP RECALL P accuracy metrics The tables are sorted by search time As we can see txtai s implementation has the fastest search times across the board But it is slower when it comes to index time The accuracy metrics vary slightly but are all about the same per method Memory usage stands out SQLite and txtai both have around the same usage per source Rank BM memory usage can get out of hand fast For example webis touch which is only K records uses GB of memory compared to MB for the other implementations Compare with ElasticsearchNow that we ve reviewed methods to build keyword indexes in Python let s see how txtai s sparse keyword index compares to Elasticsearch We ll spin up an

internal testing with solid state storage Elasticsearch and txtai s speed is about the same These times for Elasticsearch being a little slower are a product of running in a Google Colab environment Wrapping upThis notebook showed how to build an efficient sparse keyword index in Python The benchmarks show that txtai provides a strong implementation both from an accuracy and speed standpoint on par with Apache Lucene This keyword index can be used as a standalone index in Python or in combination with dense vector indexes to form a hybrid index	2023-08-17 19:22:08

海外TECH	DEV Community	Get RSS feed for your Ko-Fi account	https://dev.to/walkero/get-rss-feed-for-your-ko-fi-account-4m87	Get RSS feed for your Ko Fi accountAlmost two years ago I created my Ko Fi page where I could blog about my work on personal projects I am working on in my free time Most of them cover topics about the Amiga community and operating systems like AmigaOS and MorphOS Ko Fi com is a nice platform easy to use and express yourself One of the things I have been missing all these years is a way for anyone to follow my posts even if they are not registered on that platform The best way to do it is using RSS but unfortunately Ko Fi com doesn t provide them I get it They prefer people to register just to follow someone and potentially become their customers but platforms like Ko Fi com are for people to communicate what they love to do In my opinion every website should have RSS available because it is convenient for people to get informed about the latest blog posts using the applications of their choice So I had to do something about it I was looking for a tool that could be useful to me Different online apps grab content from websites that do not provide any RSS and create one Some didn t work with Ko Fi com at all and others were quite expensive requiring a monthly fee just to have an RSS feed In the end I found an exceptional project called RSS Bridge which does exactly what I need I just had to write some code Not a big deal We are developers after all right RSS Bridge will generate feeds based on “bridges that are developed for any site Those bridges will collect data and extract all necessary information which is then converted into various feed formats like Atom or RSS RSS Bridge is based on PHP and uses simplehtmldom to parse a website DOM to an object What I needed to do was to write a bridge for Ko Fi com and parse the content It sounds easier than it is You see the content appears using JavaScript XHR requests while it is broken into different URL paths But before that I had to create a development environment where I could do the coding I used Docker and created a docker compose yml file on my local system to build a container At first I did that on an Arm based computer and the first problem appeared Although RSS Bridge was working fine I couldn t get any data and the reason was that Ko Fi com uses Cloudflare CDN This is something that a lot of people had issues with in the past RSS Bridge solves that problem by using a special build of curl that can impersonate the four major browsers Chrome Edge Safari amp Firefox But unfortunately that library doesn t work well on Arm based systems so I had to move to my trusty Intel based Linux computer version services rss bridge container name rssbridge server image rssbridge rss bridge latestI used VS Code and the Docker plugins to get inside the container and do the coding I needed so that they are reflected instantly on the browser without the need to rebuild the container I started reading the RSS Bridge documentation and creating the first lines of the new bridge All done pretty easily and sooner than later I had the basic code working So now I had to parse the pages which worked fine having the DOM data available for me But the main Ko Fi com page doesn t have all the posts I needed I had to look deeper on the website and the HTTP requests it uses Gladly found one that returns the latest blog posts a few words from the intro and the main image That s a good start and after a few minutes fighting with the DOM I had the first RSS working But there were some issues Firstly the intro text was tiny just a few words And secondly the post dates were all relative in a way that after a few months in the past they were all the same without being able to distinguish when exactly the articles were posted Every post had a date like months ago Unfortunately that information isn t available anywhere than the main article page I decided to try and parse that one as well and get a more accurate date and the first paragraph of the whole text That worked great but made the parser a little bit slower because instead of parsing one page it had to parse So I limited it to the last posts to keep the parsing fast and now it was ready for production I set up a Docker container on one of my servers But how would I push that bridge inside the container I checked the documentation and the official RSS Bridge dockerfile and I discovered that there is an entrypoint script that checks the config folder and gets any configuration and bridge file that it finds copying them to the proper place And that happens when the container is created So I created a volume and put those files in a config folder in the host system And since I use Traefik for reverse proxy I added its labels at the end I do not care for that to work with SSL so I skipped those labels I rebuilt the container and everything worked flawlessly version services rss bridge container name rssbridge server image rssbridge rss bridge latest volumes config config restart unless stopped labels traefik enable true traefik http routers rssbridge nginx rule Host rssbridge walkero gr But I couldn t stop there Some kind of caching should be set so that it won t scan the Ko Fi com website on every RSS request and risk of getting my server IP banned RSS Bridge supports different ways of caching and I choose to use memcache which I set up in the docker compose yml file memcached container name rssbridge memcached image wodby memcached restart unless stoppedSince everything worked as intended I created a pull request to the RSS Bridge repository and after a few hours my code was merged and now every public server will have a new Ko Fi bridge for everyone to use And since this is something I will use for myself I will make sure to maintain it as long as possible RSS Bridge is a great tool that anyone can use self host expand and give back to the community so that we will help our online entity to be more free and expressive reaching as much people as possible without the need to be tied into a registration system If you have any ideas or proposals on how to make it even better please contact me and I will do my best to make that happen And if my work is useful to you I d love to hear about Oh I forgot My blogs RSS feeds are bridge

海外TECH	DEV Community	Coding Exercise Tips for Technical Candidates and Hiring Managers	https://dev.to/stoutsystems/coding-exercise-tips-for-technical-candidates-and-hiring-managers-2bge	Coding Exercise Tips for Technical Candidates and Hiring ManagersHere at Stout we screen a lot of technical candidates Our first step is to filter the resumes We have little need for glass window installers despite the fact that they match the keywords windows and installation Then we conduct a technical interview to assess a candidate s skill level For candidates who will be contracting with us directly we like the extra step of doing a coding exercise Why not just request a code sample We do like to get code samples from candidates but we rarely get useful onesーand frequently we get nothing at all Candidates are understandably leery about sharing code that is owned by the companies they ve worked for and sometimes they aren t able or willing to give an anonymized sample Sometimes we get code from hobby projects but that usually isn t deep or up to production quality Other samples are just too small to glean anything useful from Very occasionally we get code stolen from the Internet which is helpful in identifying candidates who are stupid Thus the coding exercise A good coding exercise is about more than just coding It should also be about process communication and personality working styles Our coding exercise follows a process that is common to many of our contracting projects It s geared towards remote work so it s conducted via email The programmer is given a generic task with some requirements The programmer needs to do some analysis and come up with an implementation plan along with time estimates After we ve reviewed the plan the programmer is directed to implement some or all of itーor is given slimmed down requirements as needed The programmer delivers the finished product and reports how long it took It s important to note that the tasks we give them are generic They are something any programmer can understand and don t require any specific domain knowledge While we are asking them to spend time on this exercise typically less than an hour for the analysis and somewhere around an hour for the implementation we aren t asking them to do free work The task they are implementing is for the exercise only We don t use the results The exercise must be small enough that it can be comprehended easily and implemented quickly while still being complex enough to produce meaningful results Coming up with a good exercise is quite a challenge Having programmers implement the popular FizzBuzz test would tell us whether they could code but it would tell us neither how well they deal with real problems nor whether they can analyze or estimate I ve administered our coding exercise to a number of programmers over the past few years and I ve seen some interesting results focusing on the failures here because they are more interesting Some developers aren t a good personality fit they can be difficult or unpleasant to deal with even for the length of the exercise or even fail to respond to the exercise all Some fail to comprehend requirements or follow directions Some people take a lot of back and forth iteration to understand what others grok in one go Even when told specifically to do X don t do Y some developers will ignore you and do Y anyway The quality of the implementation plans vary wildly Some come back with excellent detail and a complete plan while others come back with plans that are sketchy or actually infeasible Estimates for implementation have varied from hours to over hours though some of that is due to differences in plans or requirements Strangely some programmers will deliver code that doesn t actually work or run I ve had implementations with a single click crash bug or implementations with a lot of code that just doesn t work Makes you wonder if the programmer actually ran it Our exercise requests production quality code but apparently that s a very broad definition No coding exercise is perfect and I m sure we ve passed up great candidates who just misunderstood something or were having a bad day But our exercise gives us invaluable insight into how a programmer might operate on real world projects within our specific process and requirements Tips for CompaniesRecognizing that candidates are in short supply avoid some of the common coding exercise turn offs Don t expect a candidate to enthusiastically accept a coding exercise before they ve had an opportunity to meet with the hiring manager Most candidates won t undertake a coding exercise unless they are jazzed up about the opportunity Integrate the coding exercise into say a half day interview that includes short sessions with the hiring team Candidates are willing to make a finite investment with a company and its interview process They balk at interview after interview exercise after exercise spread out over several weeks If you want to use a coding exercise for your company first figure out what process points you want to cover For example if you do a lot of requirements gathering then perhaps you want to give them an underspecified task and have a dialog where you can see how they elicit requirements Focus on finding a task that is simple enough that it doesn t require discovery and isn t too specific to your problem domain unless you require programmers to have pre existing domain knowledge Any coding should be specific to your language platform If your company uses a practice like Test Driven Design or pair programming then your coding exercise should too It may be helpful to provide a starting project or skeleton code that has TODOs to be finished by the programmer Tips for CandidatesRead the instructions Then read them again If there is something that isn t clear ask for more information Many coding exercises deliberately leave out vital information to see how candidates address that Focus on completing features or sub features instead of bouncing around and completing nothing I d rather see a working backend with no UI or conversely a working UI with stubbed or mocked backend then have everything be a work in progress Maybe you display data but can t yet sort it or edit it As you go leave TODOs about things you still need to do That will help you not to forget things but more importantly if you run out of time it shows that you are aware of something that needs to be addressed not just that you forgot about it entirely Aim for production quality but a little under polished is okay You should absolutely do things like closing database connections preventing SQL Injection attacks or releasing disposing of resources as any production quality code should but not everything needs to be as clean and refactored as full production code This only applies to a time limited coding exercise though If you are turning in a pre written code sample I assume you think it s polished and production quality Please test your code or at least run it If I can t run your sample or it breaks with a single click you didn t anticipate it doesn t reflect well Expect your code to be reviewed by developers who know how to break things like putting text in number fields Comments and error handling matter but too much of either can be as bad as too little Again aim for what you

Ease	https://dev.to/kazemmdev/laravel101-exploring-middlewares-unlocking-multilingual-functionality-with-ease-4imm	Laravel Exploring Middlewares Unlocking Multilingual Functionality with EaseIn the previous article we added user registration functionality to our project In this article we will focus on defining access and restrictions for users using middleware in Laravel Properly defining access is crucial for any website as we want to control what actions users can perform For example as you see in previous article we don t want just anyone to be able to add a new task to our site We can achieve this by using middleware let s deep dive into middlewares in Laravel MiddlewaresAs the name suggests Middlewares just like pipelines are commands that sit between our request to the server and the server s response You might be familiar with the Auth middleware from prior lesson Let s get back to our project If you navigate to the app Http Middleware directory you will find some predefined middlewares For example one of these middlewares is PreventRequestsDuringMaintenance When you activate this middleware users will encounter a error or a message indicating that the service is unavailable usually during you perform updates or maintenance on your service In Laravel the php artisan down command is used to activate this mode and php artisan up is used to stop it As you see in following pic when your app is in the maintenance mode then the middleware prevents any requests from being executed Certainly it is also possible to exclude specific endpoints from the maintenance mode To do that you need to add your desired endpoint into the except array class PreventRequestsDuringMaintenance extends Middleware The URIs that should be reachable while maintenance mode is enabled var array lt int string gt protected except If you recall from the previous tutorial you learned that we can add a middleware to an endpoint using the middleware function Similarly you can add a middleware to a group of routes using the group function as shown below one routeRoute post logout LogoutController class gt middleware auth or a group of routesRoute group middleware gt auth function Route resource tasks TaskController class Route post logout LogoutController class gt name logout Create a new MiddlewareTo create a custom middleware we will use the following artisan command php artisan make middleware lt NameOfMiddleware gt In Laravel every middleware has a handler function where you can define its logic This function takes two inputs the request object and a closure The request object allows you to access the data within the request while the closure is a function that you can invoke to proceed with the middleware pipelines public function handle Request request Closure next return next request To use this middleware we need to define it in the kernel php file located in the Http folder Let s take a closer look at the kernel php file It contains three arrays each serving a specific purpose The first array middleware is meant for middlewares that are globally applied to all requests The next array middlewareGroups is used for applying middlewares to specific group of routes Finally we have the routeMiddleware array In this array middlewares are defined with a key allowing us to apply a middleware to a specific route For instance if you look at the list you will see auth mentioned which demonstrates how we can apply it to desired routes Now let s try something interesting Multilingual Laravel WebsiteSometimes we may need to make our website multilingual and Laravel provides a convenient tool to facilitate this To set up language resources in Laravel we first need to run the following command php artisan lang publish After running this command you will notice that in the main directory of your project there are PHP translation resources that include arrays with keys These keys represent default terms that can be found in any application You can add translations to these keys However having only an English resource might not be sufficient Let s say we want to add French as another language It can be time consuming to manually translate all the files and key values into French especially if you re not proficient in French Luckily there is another way You can add laravel lang package to your project that simplifies the process By running the following command you can install the package and add French language resources to your lang directory composer require laravel lang common devphp artisan lang add frphp artisan lang updateOnce you have set up the language resources you can proceed to add translations for specific keys For example let s say we want to add a translation for the key “welcome in both English and French languages You can do it like this gt gt lang en json welcome Welcome to Laravel tutorials gt gt lang fr json welcome Bienvenue dans les tutoriels Laravel You might be wondering how to use it right Well it s quite simple To utilize it you just need to use a handy helper function called key within your Blade files For example if you have a welcome key in your language resources you can display it on the home page of your app like this extends layouts app section title Home Page section content lt div class flex flex center justify between mb gt lt h class text xl font bold gt welcome lt h gt lt div gt endsectionAdditionally to change the locale of your application to use a specific language you can modify the locale value inside the config app php file of your project Now set the locale to fr and here is the result When it comes to translation there are a few tips that can come in handy One useful technique is to use the getLocale function to set the language in an HTML tag like this lt html lang app gt getLocale gt Another useful feature is the ability to include dynamic values within translations By passing an array of key value pairs as a second parameter to the helper function you can specify the keys you want to use for dynamic values For example hello user gt username In the above example the key user is defined for this purpose allowing you to insert the username dynamically into the translation There is also a function called trans choice that lets you translate selectively based on a given input It allows you to choose between singular and plural forms of a word For instance consider the following example translate filereturn model gt book books in blade trans choice default model gt gt gt book trans choice default model gt gt gt booksGreat We ve covered the basics of translation files and the tools Laravel provides for language management Now let s explore how we can dynamically set the language based on user selection using functions and sessions in Laravel Assuming the default language of our site is English we can configure the language and define the necessary translation keys using helper functions in the config files To handle language selection by the user we can create a controller called LocaleController and define a store function as follows use Illuminate Http Request class LocaleController extends Controller public function invoke Request request session locale gt request gt locale return redirect gt back To access this function we define an appropriate route Route post locale LocaleController class gt name locale store To display a language selection menu in the navigation blade file you can add the following code The menu mentioned above allows users to send a request to the server to indicate their desired language However there s still more work to be done We need to retrieve the selected language from every request on the server and this can be achieved using a middleware php artisan make middleware SwitchLocaleMiddlewareOnce you ve executed the command navigate to the app Http Middleware directory and define the middleware as follows public function handle Request request Closure next Response if Session has locale App setLocale Session get locale return next request Here we use two object Session and App which defined globally and are accessible with session and app you can access session from request like request gt session The App facade is a powerful object that enables us to work with various services within our project Today we ll use it to set the app s locale The Session provides a convenient and straightforward way to access data specific to the current user s request In Laravel you have multiple options for managing session data including file Redis encrypted cookies and database By default Laravel is configured to use the file session driver which is suitable for many applications In our case we re using the session to store the user s locale Now open the Kernel file located in the app Http directory and add this middleware to the end of the middlewareGroups array and in web group because the session driver defined here like this protected middlewareGroups web gt Other middleware entries App Http Middleware LanguageMiddleware class That s it By following these steps you ll have a multilingual site where you can define the translation keys in the respective language folders The final output will be as follows That s fantastic In this tutorial we explored Laravel Middlewares and discovered how they can be used to enhance our application particularly in achieving multilingual functionality I hope you found this tutorial helpful happy coding	2023-08-17 19:07:04
