海外TECH	DEV Community	Practicing Postgresql and Postulating (Im)Provements	https://dev.to/jeremyf/practicing-postgresql-and-postulating-improvements-5m	Practicing Postgresql and Postulating Im Provements Returning Again to DatabasesFor years I wasn t working with relational databases But in my heart I ve always loved them and thrived when developing with them What follows is my iterating through some SQL statements to both better understand the database and also the content I ve been using Blazer as written about on Dev to by Molly As part of my job I have access to the DEV to environment to run these queries The Reigning ChampionOne task in front of me is to improve on the Feed Algorithm To understand that I need to understand the data In the current incarnations we rely heavily on two scores article scorearticle hotness scoreTo understand the algorithms I need to look at those values Here s a query to understand the possible range of scores SELECT min score max score avg score stddev score percentile cont within GROUP ORDER BY score mean percentile cont within GROUP ORDER BY score percentile FROM articles The results min maxavgstddevmeanpercentile There s a lot of variance in the distribution of the score and anything we add to that score for sorting will be inconsistent SELECT min hotness score max hotness score avg hotness score stddev hotness score percentile cont within GROUP ORDER BY hotness score mean percentile cont within GROUP ORDER BY hotness score percentile FROM articles min maxavg stddev meanpercentile And the situation is even more swingy with the hotness score The underlying implementation works for smaller communities but as DEV to grows the swingyness becomes more and more notable The particular challenge is that the score or hotness score is the starting point for all feed queries In otherwords to get a feed tailored for the user there s a lot of variance to overcome So I decided to approach from a different angle What I have is incomplete but I m considering the structure as a strong competetor to compete against the current feed algorithm And in This CornerFirst I wanted to build some successes by writing some quick and easy queries You know practice a little bit In the examples I have user id as the placeholder for my personal DEV to account number The following query is published articles that exclude those published by people I ve blocked SELECT articles id title published atFROM articlesLEFT OUTER JOIN user blocks ON user blocks blocked id articles user id AND user blocks blocked id IS NULL AND user blocks blocker id user idWHERE published trueORDER BY published at DESCLIMIT Select the tags that I follow SELECT tags FROM tagsINNER JOIN follows ON tags id follows followable idAND follows followable type ActsAsTaggableOn Tag WHERE follows follower id user id AND follows follower type User Select the organizations that I follow SELECT organizations FROM organizationsINNER JOIN followsON organizations id follows followable idAND follows followable type Organization WHERE follows follower id user id AND follows follower type User Select the users that I follow SELECT users FROM usersINNER JOIN followsON users id follows followable idAND follows followable type User WHERE follows follower id user id AND follows follower type User Then I started doing computations in query This query creates a freshness score based solely on the publication date and excluding articles from those people I blocked SELECT current date published at date AS freshness score articles title STRING AGG tags name AS tag namesFROM articlesLEFT OUTER JOIN user blocks ON user blocks blocked id articles user id AND user blocks blocked id IS NULL AND user blocks blocker id user idLEFT OUTER JOIN taggings ON taggings taggable id articles id AND taggable type Article INNER JOIN tags ON taggings tag id tags idWHERE published trueGROUP BY freshness score articles titleORDER BY freshness score DESCLIMIT You can see the query in Blazer Next I started thinking about what I wanted out of this My initial brainstorm was that I want to create a scalar value for an article If the article has one tag that I follow I want to have a multiplier If it has two or more tags that I follow I want it to have a multiplier If it has no articles that I follow I want it to have a multiplier Using the above I then want to select all articles that were published within the last days Articles published today have a score of All other articles have a score of number of days since published I want to multiply the above scalar value for the article by the score to create a confidence value And I want the query sorted from highest confidence value to lowest The ChallengerIn wanted a query that tells me how many of an article s tags I follow of the top published articles The algorithm embedded in the following SQL statement is as follows The highest relevance score is Anything posted prior to today has a lower cap One day old is two days old is etc If I don t follow any of the tags I m not overly interested The more tags that I follow that are part on the article the higher the value If I don t follow the user that s a slight penalty If I don t follow the organization that s a slight penalty Give a bit more weight to someone I follow leaving a comment Give a bit of weight to the of comments but don t over indulge in flame wars Really discredit spam The scalars that I chose in the SQL statement are arbitrary and we d definitely want to tweak the values The query s not yet ready for primetime but I m curious to see it s effect WITH top articles AS SELECT articles id current date published at date CASE articles spaminess rating WHEN THEN ELSE END CASE ABS articles experience level rating WHEN THEN WHEN THEN WHEN THEN WHEN THEN WHEN THEN WHEN THEN ELSE END CASE COUNT comments id WHEN THEN WHEN THEN WHEN THEN ELSE END CASE COUNT followed tags follower id WHEN THEN WHEN THEN

is a relevance score between and well I suppose there could be negative numbers but that s if we have even older articles There are more things I want to consider and could add into the above query I need to account for what to do with moderator s up and down voting I need to account for folks who ve given a negative weight to a tag Next StepsI also went ahead and submitted a draft PR to begin having more conversations	2021-10-28 16:36:13
海外TECH	DEV Community	Scramjet Transform Hub — Quick Start introduction	https://dev.to/scramjetorg/scramjet-transform-hub-quick-start-introduction-3dfb	Scramjet Transform Hub ーQuick Start introduction Scramjet Transform Hub Quick Start introductionScramjet Transform Hub allows you to deploy and run multiple data processing apps called sequences Sequences are specific apps not just any apps They specialize in the efficient data processing STH can be treated both as a data processing engine and execution platform for multiple sequences running on the same platform and performing various data processing tasks We named our apps sequences and that term describes well its nature as they process data through a sequence of chained functions Therefore usually our sequences are concise and easy to write and powerful at the same time Our vanilla STH engine is based on Node js and thus allows developers to benefit from the rich ecosystem and many packages and solutions provided by this vibrant community The core part of our STH engine is called the host The Host is responsible for maintaining and deploying sequences keeping them running and managing their lifecycle Host exposes also its own REST API to provide and receive data and manage sequences and host itself What we also do on the host level is that we apply a set of algorithms to optimize and speed up data processing execution in sequences You can interact with the host using our dedicated STH CLI that will help you with both sequences deployment running it and monitoring Solution concept diagram InputsSTH can handle any input that can be handled by Node js application You as a developer are free to process a variety of inputs in your sequence applications such as Text JSON XML SOAP Audio Video and more Inputs can be either Provided to STH via its REST API orConsumed from various local or remote sources by the app such as Stream STDIN File API URLGenerated by the app itself HostThis is a solution central processing and management unit with the following major components Sequences these are the actual STH apps It is a gzipped package tar gz containing at least two files package json JSON manifest file describing the app and its configuration such as the main file to runmain file file such as index js or index ts that contains lightweight application business logic Instance once the sequence is run the host will create a separate runtime environment for it and will execute sequence code inside this runtime entity This is an instance API amp CLI our Application Programming Interface and CLI connecting to it allows both for Data operations sending input data and receiving output data and Management operations manage host itself and its entities sequences or instances OutputsOur engine outputs can be managed in several ways File you can save your output to the local or remote fileSTDOUT output can be directed to system STDOUT STERR is supported as well API output can be consumed from our STH REST APIURL Request you can write your app in a way to request URL webhook etcStream output can be streamed to a particular destinationyou can mix multiple actions together you can both send data to a remote system URL and save it locally Install Scramjet Transform Hub Prepare environmentIn order to install Scramjet Transform Hub please follow these steps Get Linux machine local UNIX Linux OS cloud VM etc Install Docker on this Linux machine official Docker instructions are here Install npm on this machine official instructions are here Currently we recommend Node js version x LTS Install STHOpen one Linux terminal window and issue the following commands Install Scramjet Transform Hub and STH CLInpm i g scramjet sth scramjet cli Run STHscramjet transform hub Run your first sequence Review the packageNote that all commands here are executed from the root of this repositoryWe have prepared for you a simple hello snowman sequence that you can use This sequence is available in the directory samples hello snowman in this repository In this directory you will find two files package json the manifest file that describes this particular sequenceindex js file containing main application logic This particular application is written in plain JavaScript to simplify this example However you can also write your sequences in TypeScript and build them before packaging and sending the sequence to STH There is no need to change anything in our hello snowman sequence for a first run Let s move to the next step Prepare and send sequence packageOur sequence apps need to be packaged before can be sent to Transform Hub This package is a simple TAR archive and our STH CLI has a special command to package the app directory into sequence tarball Note any time you can display STH CLI help by issuing terminal command si help for general help or si lt command gt help for specific command ie si sequence help Please open a new terminal window and keep the first one with STH running Then issue the following commands in the root directory of this repositorya pack directory hello snowman into archive hello sequence tar gzsi pack samples hello snowman o samples hello snowman tar gzThere is no output shown in the terminal but you can verify with ls that the tarball package is created inside the samples directory b send hello snowman tar gz to the running host default localhost API endpoint will be used by the CLI send command si sequence send samples hello snowman tar gzthe output will look similar to this one Request ok api v sequence status AcceptedSequenceClient id cfcc b d b acc host HostClient apiBase api v client ClientUtils apiBase api v log Object sequenceURL sequence cfcc b d b acc Now we have uploaded sequence to the host and host assigned to it a random ID GUID in my case our sequence ID is id cfcc b d b acc The Host also exposes REST API endpoint for each sequence and this is also described in this response Run the sequenceWe can now use sequence ID to run this uploaded sequence The command is si seq start lt sequence id gt You can also pass an arbitrary number of parameters by providing them after in case of our hello snowman parameters are not used For example for the above sequence we could write si sequence start cfcc b d b accthe output would look similar to this one Request ok api v sequence cfcc b d b acc start status OKInstanceClient host HostClient apiBase api v client ClientUtils apiBase api v log Object id ed acfc e b aacb instanceURL instance ed acfc e b aacb A sequence is an app template Once run it will become live as a new instance The instance also receives its own ID GUID In this case instance Id is id ed acfc e b aacb Of course sequences can be run multiple times Each run will create a separate instance with a distinct instance id Send data to the sequenceWe want to make your life easier and for this very example we have prepared a special Node js app that will generate a stream of simple messages and send them to our running instance of hello snowman For fun our stream generator will send simple text messages containing temperature readings from an artificial weather station Temperature values will be generated randomly in the range of lt gt degrees Celsius Our hello snowman app will read and interpret these messages and will inform us about the state of our Snowman if the temperature will be or below the sequence will return the message Snowman is freezing in the other case temperature above degrees the sequence will return the message Snowman is melting To run this app please execute this command from the root of our directory node tools stream gen tool stream gen js lt instance id gt In our case this would look like this node tools stream gen tool stream gen js ed acfc e b aacbthe output would look like this Message Temperature measureINPUT OUTPUT Snowman is melting Message Temperature measureINPUT OUTPUT Snowman is freezing Message Temperature measureINPUT OUTPUT Snowman is freezing Our sequence generator app does two things here Sends stream of messages each one containing a number with temperature valueReads output from Host API that is generated by our hello snowman sequencesSeparately you can also open a new terminal window and see a log of this particular instance with command si instance log lt instance id gt In our case this would besi instance log ed acfc e b aacbthe sample output will be similar to this one T Z log object Runner Input message lt Buffer gt T Z log object Runner Input message lt Buffer d gt T Z log object

海外TECH	Engadget	Panasonic GH5 II review: A vlogging classic gains speed and streaming powers	https://www.engadget.com/panasonic-gh5-ii-review-speed-streaming-powers-164600927.html?src=rss	Panasonic GH II review A vlogging classic gains speed and streaming powersPanasonic s GH was such an iconic vlogging camera that Panasonic unveiled two Micro Four Thirds successors to replace it The GH due to arrive later this year has major upgrades like K p and even K video The other is the model I m reviewing today the GH II As the name suggests the GH II is more of a refresh with the same megapixel Micro Four Thirds sensor However it has an all new processor that delivers significant improvements in speed video quality and AI smarts Best of all it s less than the GH was at launch The big question is whether it s worth getting this model waiting for the GH or even purchasing an older GH that s now steeply discounted To find out I tested the GH II s new features video quality autofocus and more ーhere s what I found out Body and handlingSteve Dent EngadgetIf you re already familiar with the GH you ll be very comfortable with the GH II ーthe bodies are nearly identical That s a good thing because it still out handles many newer cameras thanks to the excellent grip and logical control positions There are a few key changes though While the rear display is a little smaller at inches instead of inches it has slightly more resolution and is significantly brighter That fixes one of the biggest issues with the GH its relatively dim display The electronic viewfinder EVF carries the same million dot resolution and x magnification but has double the refresh rate at Hz That makes a noticeable difference in image quality more so than a resolution bump in my opinion However it also drains the battery a touch faster Another nice improvement is the addition of USB C PD compatibility that can charge the battery more quickly And it comes with a more powerful DMW BLK battery the same one found in the company s full frame S camera While it s still CIPA rated for shots like the GH it delivers a few more minutes of video recording Steve Dent EngadgetThe GH II has better menus than the GH gaining those introduced on the GHs It s a color coded tabbed menu system with hints to find the option you re looking for It also has the info panel from Panasonic s pro Varicam models also available on the GHs that show important settings at a glance Another feature for pro shooters is dual zebra controls that let you check two levels at once like highlights and skin tones As with the GH the new model has dual UHS II card slots but they now support the maximum V MB s speeds That ll ensure stable capture if you re using the new All I K video settings at up to Mbps or let the buffer clear faster if you re snapping photos Video performanceThere are several subtle but important changes to the video capabilities of the GH A key one is an update to the image stabilization system It now delivers up to EV of shake protection up by EV over the GH When working with compatible lenses and using the IS boost mode it s designed to provide more steady shots even if you re walking or moving No in camera stabilization system is ever going to beat a gimbal However the GH II does a better job than most mirrorless cameras I ve tried at smoothing out walking or running provided you re reasonably careful More importantly it makes handheld camera pans and other motion smoother than the GH does If you need some extra stabilization there s an electronic mode that does help though it crops in slightly Another key change is with the autofocus system In general continuous autofocus for video is faster and smoother than before though you ll still see a tiny bit of hunting or wobble that s unavoidable with a contrast detect only AF system As before the system works better at higher frame rates when it has more information to work with Steve Dent EngadgetThe GH II also brings some AI autofocus smarts that couldn t be added via firmware to the GH because of its relatively old processor It offers double the face and eye tracking speeds and can pick up focus when a face is tilted away from the camera It can recognize heads and human bodies making tracking more feasible if a person is turning or moving towards or away from the camera It adds new animal tracking features that can handle most pets and some types of wildlife as well With these features enabled it s easier to keep someone in focus if they or you are moving Again this works best at higher frame rates but overall the improved focus hit rates make the camera more practical for vlogging or run and gun work especially for solo operators Animal tracking is also pretty useful particularly if pets and or kids are running around Is the GH s subject tracking as good as on Canon or especially Sony s latest mirrorless cameras No because both of those brands use phase detect systems that can nail focus directly without any wobble Sony s latest models particularly the A and AS III also have uncannily fast tracking capabilities that Panasonic has yet to match Still the new model is a big step up from the GH and certainly good enough for many types of projects Video qualitySteve Dent EngadgetVideo made the GH popular as it was far ahead of the competition for the price when it first arrived Five years on it s getting pretty old though so a new processor helped Panasonic boost the GH II s specs in line with what it s done on full frame models like the S To that end the new model now offers bit K and CK x video at up to fps rather than just bit video at p as before That makes it better for slow mo or high frame rate video if you want to use log or HDR video settings Like the GH it can also handle K p anamorphic x with bit color settings And where All I capture was limited to fps on the GH the GH II can now do it at up to fps Though the GH II comes with VLog L shooting out of the box it s limited to stops of dynamic range rather than like Panasonic s BGH box camera and other recent models Panasonic also introduced two new video modes Cinelike D and Cinelike V that let you shoot log like video with less hassle Those deliver slightly more saturated colors and improved skin tones than the original Cinelike D and V modes Like other newer models the GH II shows a red frame around the screen while recording along with aspect ratio guides and a TikTok style portrait video mode With the same sensor the GH II has pretty much the same readout speeds so as before rolling shutter is present but well controlled Steve Dent EngadgetThe GH II can now capture video simultaneously to an external recorder over the HDMI port unlike the GH However it can t capture RAW video like the S for instance Hopefully that and the limited VLog L dynamic range will be addressed in future firmware updates With all those tweaks the GH II delivers sharp video with high levels of color accuracy for demanding work It handles skin tones well and colors are natural and accurate Low light shooting is not its strong point though due to the smaller sensor size For that you d be better off with either the GHs or one of Panasonic s newer full frame models The new video quality changes are subtle but could be helpful for certain types of work Overall it delivers the video quality everyone liked from the GH plus a little more Live StreamingSteve Dent EngadgetA key new feature for the GH II is the ability to broadcast live on the web either using WiFi or a USB C The latter will require a firmware update that essentially allows the GH II s USB C port to be used as a wired LAN connection however You can either stream to a smartphone via WiFi using the Lumix Sync app or stream directly over WiFi without the need for a PC or phone The latter requires you to use the Lumix Network software for PC or Mac to write your streaming settings to an SD card Since it uses the RTMP RTMPS standard it supports YouTube Facebook and other services Better still it supports camera audio as well as video Live streaming does require a robust connection however as I struggled to maintain a livestream in the countryside with a Mbps connection You won t want to use the maximum p fps settings unless you have internet speed well above Mbps PhotosWith the same sensor as the GH the GH II delivers much the same image quality and photo shooting specs including fps burst shooting speeds Where it has improved though is in the autofocus features particularly with tracking The G was always a better photo camera than the GH as it had a noticeably quicker autofocus system However the GH II s new processor means faster AF calculations so the hit rate with continuous burst shooting is higher It can also do face and eye tracking more quickly and as with video can handle head and body tracking too With those changes I was able to get more burst action shots in focus than I could with the GH whether shooting people dogs or horses At the same time it tends to nail exposure more accurately than the original model Image quality is largely along the same lines as video with low light capability that gets pretty noisy above ISO or so but sharp color accurate photos in good light As before it s best not to let your highlights get too blown out as they re difficult to recover when shooting RAW Wrap upSteve Dent EngadgetThe GH II is a worthy upgrade to the original bringing enough improvements and new technology to justify its existence Given that the all new GH model is coming soon as well it s clear that Panasonic is still committed to small sensor video centric mirrorless cameras Video has modestly improved and it s better for handheld shooting thanks to the improved stabilization Autofocus is still a drawback but it s faster and more reliable than before It would be nice if it supported RAW external capture but that s probably not a dealbreaker for most users It can handle stills reasonably well though it s not the camera s strong point Other cameras have caught up with the GH II in terms of video performance but most like the Canon R and Nikon Z II are more expensive Fujifilm s X T is a better choice if you want a larger sensor and shoot a lot of photos but it lacks the streaming capabilities Its biggest rival may be the original GH that can now be found for if you don t need the video streaming or other features In any case the GH II is now the best Micro Four Thirds mirrorless camera for video At least until the GH comes along	2021-10-28 16:46:00
