海外TECH	DEV Community	Boldness in Refactoring	https://dev.to/codenameone/boldness-in-refactoring-2h4g	Boldness in RefactoringThe old engineering adage “don t touch it it works Is terrible Don t listen to it It might be OK at a small scale but as time goes by the bit rot spreads through your code and servers polluting everything Large swaths of your system become “no man s land As you re developing a new system you must always “touch it and make sure we hire engineers who aren t afraid to do so Yes I get it I said that sentence frequently in the past I understand the motivation Management doesn t care about the bit rot in our future They care about the here and now Why are you wasting time on this feature  It s working Don t you have enough on your plate already Are you the Marie Kondo of coding Does this code not spark joy It s more like a bad apple in a barrel Bad code and forbidden zones tend to grow and metastasize A living project needs to be fully accessible by the current team It can keep working without that but that makes every future step painful  When we have a flexible team with a relatively small and familiar code base touching everything isn t challenging It s easy in that case   The Legacy ProjectThe hard part is touching code in legacy projects As a consultant I had to do that often How do you enter a project with a million lines of code and start refactoring The nice thing is that we re all alike The engineers that built the project were trained with similar books and similar thought processes Once you understand their logic you can understand why they did something But a large part of the difficulty is in the tooling Projects that were built years ago used tools that are no longer available The code might no longer compile on a modern IDE Our immediate reflex would be to try to use an old IDE and old tooling  That might be a mistake  Old tools keep the stale bit rot This is an opportunity Revisit the project and update the tools A few years ago I did some work for an older C codebase I didn t understand the code base but the original developers built it in an older version of Visual Studio Getting it to work on my Mac with LLVM and VS Code helped me visualize the moving pieces more clearly Once I had a debugger up and running fixing the bugs and weird issues became trivial I can t say I fully understood that codebase But the process of porting and updating the tools exposed me to many nuances and issues When You Can tThe flip side of that were cases where an existing legacy system is a customer requirement I had to implement integrations with legacy systems that were external black boxes We didn t need to touch their code but we needed to interface with these systems and rely on their behaviors This is a very challenging situation Our solution in those cases was to create a mock of the system so we can simulate and test various scenarios In one such situation we wrote an app that sent requests and saved responses from such a “black box to create a simple recorder We then used the recordings as the basis for tests in our implementation This might not be an option since sometimes the black box is directly wired to production directly to the stock market in one case  My rules for dealing with such a black box are A single isolated module handles all the connections that way we can build uniform workarounds for failures We can use a physically isolated microservice which is ideal for this specific case Expose results using asynchronous calls this prevents deadlocks and overloading a legacy system We can use a queue to map causes of failure and error handling is simpler since a failure just won t invoke the result callback We need to Code defensively Use circuit breakers logging and general observability tooling Expect failure in every corner since this will be the most contentious part of the project Once we wrap that legacy we need to trigger alerts on the failures Some failures might not bubble up to the user interface and might trigger retries that succeed This can be a serious problem E g in a case of a stock market purchase command that fails a trader might press retry which will issue a new successful command But the original command might retry implicitly in the legacy system and we can end up with two purchases Such mistakes can be very costly and originate from that black box Without reviewing the legacy code fully and understanding it we can make no guarantee What we can do is respond promptly and accurately to failures of this type Debuggability is important in these situations hence the importance of observability and isolation in such a black box Confidence Through ObservabilityIn the past we used to watch the server logs whenever we pushed a new release Waiting for user complaints to pour in Thanks to observability we re the first to know about a problem in our production Observability flipped the script  Unfortunately there s a wide chasm between knowing about a problem and understanding it fixing it and noticing it If we look at the observability console we might notice an anomaly that highlights a problem but it might not trigger an alert even though a regression occurs A good example of that would be a miscalculation A change to the application logic can report wrong results and this is very unlikely to show in the observability data  In theory tests should have found that issue but tests are very good at verifying that things we predicted didn t happen They don t check against unexpected bugs E g We might allocate a field size for financial calculations and it worked great for our developers based in the USA However a customer in Japan working in Yen might have a far larger number and experience a regression because of that limit We can debug such issues with developer observability tools but when we deeply integrate legacy systems we must apply the fail fast principles deeply that way the observability layer will know of the problem We need to assert expectations and check for conditions not in the test but in the production code Here an actual error will be better than a stealthy bug A lot of focus has been given in languages to the non null capabilities of languages But the concepts pioneered in languages like Eiffel of design by contract have gone out of fashion This is understandable it s hard and awkward to write that sort of code Checked exceptions are often the most hated feature of the Java language Imagine having to write all the constraints you expect for every input Not to mention dependencies on the environmental state This isn t tenable and enforcing this check in runtime would be even more expensive However this is something we can consciously do in entry points to our module or microservice The fail fast principle is essential when integrating with legacy systems because of the unpredictable nature of the result SummaryIn the s I used to take a bus to my job Every day as I walked to the office I would pass by a bank machine and every time it would reboot as I came close This was probably part of their cycling policy banks have a culture of rebooting machines on a schedule to avoid potential issues  One morning I went by the machine and it didn t reboot I did what every good programmer hacker would do I pulled out my card and tried to use it It instantly rebooted and wouldn t take my card but the fact that my instinct was to “try is good Even if it isn t the smartest thing in the world we need to keep code accessible and fresh Legacy code isn t a haunted house and we shouldn t be afraid	2023-04-04 13:44:27
海外TECH	DEV Community	Extending Vendure's functionality with custom plugins	https://dev.to/prasmalla/extending-vendures-functionality-with-custom-plugins-3l5c	Extending Vendure x s functionality with custom pluginsTL DR monkey patch is monkey business use plugin architecture instead Monkey patching is a way to change extend or modify software locally While this may be done as a workaround to a bug or a feature a better approach is to contribute to the project if it is open source to help the community and or if you are writing a new feature extend it as a custom plugin when where supported Vendure is a modern open source headless commerce framework built with TypeScript amp Nodejs with an awesome plugin architecture to keep the monkey business at bay Use case product inventory goes out of stock this is a good thing but when a potential customer sees out of stock is when it s not Wish case let the customer know when the product is back in stock  Let s build a custom Back In Stock plugin Here is quick intro to writing a Vendure plugin to get you started with the basics We will be using the starter plugin template provided by Vendure for reference to start our journey Here is the initial plugin setup that includes the entity GraphQL api extensions resolver for it and the service that talks to the database We will be adding email notification here later src plugins vendure

ProductVariant nullable false productVariant ProductVariant ManyToOne type gt Channel nullable false channel Channel ManyToOne type gt Customer nullable true customer Customer Column varchar nullable false email string After defining a new database entity we expose the entity in GraphQL API We add our types queries and mutations here and will use GraphQL codegen to generate our types later src

海外TECH	DEV Community	Vector Databases	https://dev.to/josethz00/vector-databases-5df1	Vector DatabasesWith the rise of AI vector databases are becoming more popular But what exactly is a vector database and when should you use it What is a vector database Traditional search engines use full text search but NLPs like ChatGPT and Bing AI use semantic search or similarity search a type of search that considers not only the characters match but also the meaning of the words This feature of semantic search is powered by vector databases Recently Google also started using semantic search  Full text search VS Semantic searchLet s compare these two types of search Full text searchSearch for a word or phrase in large amounts of textThe search engine returns a list of documents that contain the search termSELECT title contentFROM documentsWHERE search vector plainto tsquery english example search Semantic searchSearch for a word or phrase in large amounts of textThe search engine will return a list of documents that contain the search term or have a similar meaning  How does vectorization work Vectorization is the fundamental of vector databases so first we need to understand this technique and its advantages NLP ExampleA NLP receives a text as input and returns another text as output This involves several processing steps one of them is vectorization In the vectorization process the tokens of the input text are converted into vectors using linear algebra operations Simplifying A text becomes an array with numeric values for example learning NLP and AI gt The result of this translation is called a vector embedding The vector embedding is a numerical representation of the input text It works not only for text but also for images audio and video Each of these types of data use a different algorithm to generate the vector embedding   Vectorization algorithms Images vgg resnet inception mobilenet googlenet etc Text wordvec glove fasttext BERT nodevec etc Audio wavvec mxnet etc   Finally the vector database Now we have a lot of vectors but these vectors are basically numbers matrices they don t mean anything by themselves So the vector database is used to index these vectors The vector database will index the vectors leaving the vectors with similar values close to each other this makes it possible to perform a similarity search in the database   How the vector database knows which vectors are similar Querying the database using math formulas to find the closest vectors in a high dimensional spaceEuclidean distanceCosine similarityMachine learning algorithmsK nearest neighbors KNN Approximate nearest neighbors ANN Indexing Examples Example with football players Let s suppose you want to search for the following text Best football player in the world You will very likely get results talking about Messi because currently he was elected the best football player in the world But you will also get results talking about Cristiano Ronaldo Mbappé Neymar etc as they are also very good football players and considered the best by many fans   Performing a semantic search in a dataset Load the dataset first articlesdataset load dataset openwebtext split train Preprocess the datasettexts simple preprocess article text for article in dataset Train a WordVec modelmodel WordVec texts vector size window min count workers Find the most similar words to politics global and economysimilar words model wv most similar positive politics global economy topn print similar words In this code we are performing a semantic search on the terms politics global and economy As result we get the most semantically close terms with the term and the numerical proximity coefficient gt gt gt most similar results to politics global economy debt industry conflict labor scientific investment capitalism participation society crisis Complete code   Most popular vector databasesFaiss by Meta PineconeMilvusPostgres pg vector Weaviate	2023-04-04 13:19:09

海外TECH	Engadget	The best wireless headphones for 2023	https://www.engadget.com/best-headphones-150030794.html?src=rss	The best wireless headphones for Over ear noise canceling headphones typically offer the most comprehensive set of features we want for our listening pleasure The best of these wireless options combine stellar audio with powerful active noise cancellation ANC and other handy tools to create as complete a package as possible Of course some companies do this better than others For Engadget s best wireless headphones guide we tested out a number of different models with a variety of features including noise cancellation and sound quality Plus our favorites span a range of prices so you can decide how much you re comfortable spending Best overall Sony WH XMSony s X line has been our top pick for best wireless headphone for a long time now Until another company can pack in as many features as Sony and do so with a stellar mix of sound and effective ANC the crown is safe With the WH XM Sony redesigned its flagship headphones making them way more comfortable to wear for long periods of time The company also made noticeable improvements to the active noise cancellation adding a separate V chip in addition to the QN that was inside the M There are now eight total ANC mics as well the previous model only had four This all combines to better block background noise and high frequencies including human voices The XM still has all of the features that typically make Sony s top of the line headphones showstoppers That includes hour battery life and crisp clear sound with balanced tuning and punchy bass A combo of touch controls and physical buttons give you on board access to music calls and noise modes without reaching for your phone Speak to Chat automatically pauses audio when you begin talking and like previous Sony headphones the M can change noise modes based on your activity or location Plus this model offers better call quality than most of the competition The only real downside is that they re more than the WH XM at full price Runner up Bowers amp Wilkins Px SI ll admit I didn t expect Bowers amp Wilkins to make the year s best headphones list or even be in contention for a spot However the company s revised Px headphones impressed me during my review The Px S are pricey at but Bowers amp Wilkins pair impressive audio quality with solid ANC performance In fact the Px S are my favorite headphones right now in terms of sound There s also a more refined design that doesn t look overly plasticky and the headphones fit comfortably even after hours of use Call quality ambient sound and automatic pausing aren t the best here but they get the job done At the end of the day the design sound quality and noise cancellation make the Px S a strong pick in the current true wireless headphone field Best budget Audio Technica ATH MxBTAudio Technica has introduced affordable wireless headphones in the past and while they didn t offer active noise cancellation they re still worth considering The company s latest is the MxBT a Bluetooth version of the A T s popular Mx wired cans For just you can expect a comfy fit and up to hours of battery life Bluetooth multipoint connectivity allows you to connect to multiple devices at once and physical buttons provide reliable on board control The design isn t as refined as the company s pricer models like the MxBT but you get the bulk of what makes Audio Technica s cheaper options so good Another solid option Bose QuietComfort The Bose was one of our top wireless Bluetooth headphones last time around but the company recently revived a workhorse with the QuietComfort The design is mostly unchanged from the previous QC models which could be a deal breaker for some Once you get past that though the QC combines Bose s excellent active noise cancellation with clear and balanced audio You can expect up to hours of battery life on a charge and a comfortable fit that doesn t get tiresome during long listening sessions We ve already seen them on sale for less than full price which makes the QuietComfort even more compelling Another solid option Technics EAH ABack at CES Panasonic announced the EAH A a new set of active noise canceling headphones under the iconic Technics brand While most of the features are what you see on any number of wireless headphones one figure stood out The company says you can expect up to hours of battery life on the A and that s with active noise cancellation enabled These are currently in my stable of review units for detailed analysis but I have already tested them on a long flight The ANC is impressive and they re comfortable enough to avoid becoming a burden after several hours Sound quality is also quite good there s LDAC support too and there are enough features here to justify the premium price tag Another solid option Master amp Dynamic MWWhile Master amp Dynamic is known for its design prowess the company s over ear headphones were due for a refresh With the MW that debuted in June the company opted for a look that takes cues from its MG gaming headset and mixes them with a combo of aluminum leather and tempered glass The company s trademark sound quality returns with multiple ANC modes and ambient sound options for a range of situations At the high end looks don t come cheap but if you re looking for something beyond the pure plastic fashion of most headphones M amp D has you covered Another solid option Sennheiser Momentum I ll be honest I had a hard time choosing between the Px S and the Momentum for the runner up spot this time around However Bowers amp Wilkins gets the edge in terms of design even though the Px S and the Momentum are very evenly matched on sound quality They re the two best sounding sets of Bluetooth headphones I ve tested this year and it s not even close Sennheiser does have an impressive hour battery life in its favor and improved ANC performance Those two items alone might be enough for you to overlook the very generic design FAQsHow can you tell the quality of headphones I typically look at three factors design sound quality and features In terms of design I m usually looking to see if headphones feel cheap and plasticky Plenty of companies use plastic but they can do so in a way that doesn t look or feel like budget models For sound quality I want to hear a nice even tuning where highs mids and lows are all well represented No overly boomy bass or scooped out mids I also want good clarity where you can pick up fine details and an open immersive soundstage Features is typically a distant third but if a company doesn t cover basic functionality automatic pausing transparency mode multipoint Bluetooth etc it can be an indication of overall quality nbsp How do I choose the best quality headphones “Best can be pretty subjective but I always recommend going to a place where you can listen to the headphones you re thinking about buying before you commit Sometimes this isn t possible so you ll want to check return policies I also recommend doing some research to determine what your priorities are in a new set Do you want the best sound quality Is powerful active noise cancellation ANC the most important Would you rather have conveniences like automatic pausing Which brand has the best headphones Sony consistently tops our list with its X line This is mostly due to the combination of sound quality ANC performance and the truckload of features these headphones pack in I ll be the first to tell you that there are better sounding options and other companies like Bose offer more effective noise cancellation But when you add everything up no one comes close to the full slate of tools Sony puts in its premium headphone line Do expensive headphones sound better Exorbitant price tags don t mean better audio quality Bowers amp Wilkins headphones are on the high end for wireless noise canceling models and they sound amazing However Audio Technica s MxBT is much more affordable and doesn t have ANC but these headphones have a warm natural sound profile that I find very inviting At the end of the day it will come down to personal preference but you don t need to spend a lot to find great headphones This article originally appeared on Engadget at	2023-04-04 13:49:55
