海外TECH	DEV Community	AWS VPC Basics. Building your first VPC with a public and private subnet	https://dev.to/leewynne/aws-vpc-basics-building-your-first-vpc-with-a-public-and-private-subnet-22ll	AWS VPC Basics Building your first VPC with a public and private subnetHey there Manually building your first VPC with a public and private subnet should definitely be one of your AWS newbie tasks it will allow you to quickly get a grasp of how VPCs work and what we are trying to do here and why Of course you can use the VPC wizard to do this but it is helpful just to create your first VPC manually this way you can get an indication of the subnet ranges and services required to get you going with your very first VPC that has both a public and private subnet both ready to host ec instances These are the things we want to accomplish here Select an AWS regionCreate a VPC a virtual private data centre within the selected region Assign a network address range to our VPCConsider the subnets ranges you want to use with the VPC address range we will be using Create a single public subnet for one availability zoneAttach an Internet Gateway for our public subnet Create a single private subnet for one availability zone We are using single availability zones only designing fault tolerant distributed systems across multiple availability zones would be something that you would definately do in production Let s get started Select a regionLogin to the AWS console and then choose the region at the top right I am going for London eu west Create a VPCNow hit the services drop down option at the top and choose VPC under Networking amp Content Delivery from there hit create VPC at the top right Fill in the new VPC detailsNext up use the following details to fill in the VPC form Name tag your vpc name IPv CIDR block this will give us IP addresses to split up across the whole VPC in various subnet ranges Tenancy choose DefaultI have put some resource tags in as examplesHit create Create the public subnetYou should still be in the VPC part of the AWS console so look to the left and there will be a link to subnets hit that link At the top right hit create new subnetSelect the VPC that we just createdLet s give the subnet a relevant name I am going for public subnet myawesomevpc eu west a specifying public or private resource type vpc name and then region az For this example I am going for a subnet in each AZ giving us a total of per subnet excluding management IPs so Hit create Create the Internet GatewayOkay so what makes the public subnet actually public and different than the private subnet The answer is simple you attach an Internet Gateway to your VPC and then update the associated routing table to allow Internet traffic in and out of the subnet Let s do that now Still in the VPC dashboard under subnets hit Internet gateways Top right again hit create new Internet Gateway From there fill in the Internet gateway form Name fill in a descriptive nameTag the resource appropriately Hit create Done Associating the Internet Gateway with our VPCHit Internet gateways again in the console then click on the Internet gateway ID in the list At the top right hit actions and then attach to VPC and from there select the VPC we created earlier Update the public subnet route table to send traffic to the Internet Now when we created our public subnet AWS kindly created a route table for it so all we need to do here is associate our new Internet gateway with a new route out to the Internet You ll still be under the VPC dashboard hit subnets then under subnets hit route tables and select the link under the route table ID This will open up the route table Towards the right hit edit routesHit add route and insert and then to the right select the Internet gateway that we created earlier Hit save changes Okay cool now we have a VPC public subnet route table and Internet gateway setup If you want to drop an ec instance into the public subnet all you would need to do is give it an Elastic IP address and you ll be able to access it from the Internet ensuring that you configure the security group for the ec instance and lock it down Create the private subnetThis is somewhat easier As all we are doing is following the steps above but not associating the route table associated with the subnet to an Internet gateway You should still be in the VPC dashboard so again head towards subnets Again we need to select our existing VPC and we will provide another subnet range Fill in the form like this VPC ID select the VPC we created earlier from the drop down Subnet name private subnet myawesomevpc eu west aAvailability Zone I am again choosing London eu west a as both my public and private subnet are in the same data centre and subnets do not span availablity zones in AWS IPv CIDR block Add some optional tagsThat s it Now if you drop an ec instance into your private subnet it won t be accessible from the Internet because there is no direct route out to the Internet however ec instances in all subnets can communicate with each other because the VPC has a default router than ensures that all subnets know how to make contact with each other It is therefore up to you to ensure that routes are locked down and source destination configuration takes place through ec security groups and network access control lists There is more to come I ll write another post that explains how to add a NAT gateway to your private subnet that will allow ec instances to access the Internet through a mask but no traffic will be allowed back in directly therefore it remains private You may always want to route the AWS private network into an on premises network through a VPN or MPLS network again that is for a later post	2021-07-13 15:50:45

海外TECH	DEV Community	Should You Invent a New Query Language? (Probably Not)	https://dev.to/arctype/should-you-invent-a-new-query-language-probably-not-2mof	Should You Invent a New Query Language Probably Not What s worse than data silos Data silos that invent their own query language Erik BernhardssonIn his infamous and widely discussed blog post named I don t want to learn your garbage query language Erik Bernhardsson expressed what so many other Data Engineers and Analysts related with so strongly Namely that he really doesn t like software that invents its own query language and that he just wants his SQL back The fairly short yet passionate rant summarized the almost universal experience that technologies that require their own language often produce a whole new different set of complexities There has been an explosion of different types of databases in the last years Just take a look at the sheer number of NoSQL database types in my last article and increased specialization is forcing Data Engineers and Analysts to learn an even greater number of new programming languages Each of them has its own syntax and specific weirdness and while ORMs sometimes help they often make things even more difficult That being said new Query Languages are often necessary like in the case of NoSQL databases This begs the question how can we tell whether a new language actually adds more value than problems it creates To answer this we need to take a deep look at what causes all this conflict Why are there so many Query Languages There are a lot of Query Languages out there So many that even the most comprehensive lists leave out many important players I wouldn t even want to attempt to gather a list like this because it seems new ones are added every minute So let s take a look at what causes this In short there are so many different Query Languages because there are so many different things to query In addition data often has to be stored in various models with varying kinds of schemas and varying degrees of separation between physical and logical schema For example data stored in a relational database requires different technology and syntax than data stored in JSON files An early hierarchical or network database query language will look quite different from a relational query language In the early days of databases one had to explicitly navigate the paths between records That also explains why the last decade has been particularly fruitful due to new challenges created by NoSQL Just take a look at the number of different NoSQL categories in my last blog post Even within relational databases different vendors want to offer special features and functions through their own SQL dialects T SQL PostgreSQL etc All of this adds up quickly and in retrospect it was inevitable that we would end up with a myriad of options to store and query data Overall that is actually an excellent thing because that way there is constant improvement through competition However development slowdowns due to too many different query languages persist so Object Relational Mappers ORMs were invented As we are about to see though they also often complicate things even more Why ORMs Don t Always HelpLet s first take a deeper look at what ORMs are and why you might want to use them Object Relational Mapping is a process often used in computer science to convert data between incompatible type systems through object oriented programming languages The goal is to create an abstract database layer of database objects that can then be queried using the programming language of your choice Long story short it allows you to interact with your database using your language of choice instead of that database s Query Language This is best explained through a quick example using SQL SELECT FROM users WHERE name Jane Doe Object relational mapping is the idea of writing queries like the one above and much more complicated ones using the object oriented paradigm of your preferred programming language That is where ORMs come in ORMs libraries that implement this technique in different programming languages For example using a JavaScript ORM the above query would now look something like this var orm require generic orm library var user orm users where name Jane Doe There are of course plenty of good things that can come from using an ORM No SQL If you ve read my blog post about learning SQL but still aren t convinced that you should learn SQL then ORMs allow you to use a programming language of your choice No Dialects ORMs abstract away the database system so that switching from MySQL to PostgreSQL for example is much easier Extra Features Some ORMs have advanced features such as support for transactions connection pooling migrations seeds and streams that can be useful in some cases Performance If you really aren t any good at SQL then an ORM will perform better than you for some queries As you probably already deduced from the title of this section there are also plenty of cons Performance If you are a master at SQL you can probably get more performant queries by writing them yourself Learning ORMs don t work like normal Query Languages so if that s what you are used to there is overhead involved in learning how to use them Too Many The learning problem only worsens when you consider just how many different ORMs there are and each has its own learning process Configuration The initial configuration of an ORM can take a long time and be a pain Black Box The layer of abstraction that ORMs provide can hinder getting at the real problem of a query or database issue To summarize ORM s alleged benefit is that they cut down development time by adding an abstraction layer but it often produces an even bigger headache Instead of using SQL you now have to scroll back and forth in some ORM documentation to determine how to write the most basic queries Debugging can also be an issue because sometimes an ORM translates a query into some monstrosity that joins tables using a full table scan and you end up with bloated higher level data classes rather than easy to understand tuples or dicts that contain the data in a dumb simple format that is trivial to introspect So ORMs can be useful but don t necessarily help with the underlying problemーthere are already too many query languages So what can be done Should we follow Erik s advice and put a year moratorium on inventing new query languages When Should You Invent a New Query Language While Erik s call for a moratorium was certainly more of a joke than a serious solution I think it did express the sentiment that we need to stop adding so many query languages so quickly pretty well It s certainly appreciated that many of these are necessary to deal with new classes of data new ways that data is stored or simply too much new data but how do we know which ones were necessary and which ones weren t This is why I suggest a few simple guiding questions and rules for any new developer who might feel the urge to add to the query language ecosystem Is My Language Just Another Dialect This one seems too obvious but even big organizations like Oracle and Microsoft couldn t quite follow this rule resulting in dialects like T SQL and PL SQL At this point almost every database has its own ways of defining stored procedures functions triggers and differences that are even more pronounced than for queries and data definitions For example the scripting language for Sybase and SQL Server is called T SQL Strictly speaking SQL Server is the database and T SQL is the language but the two are often used interchangeably when referring to code MySQL s scripting language is quite different from T SQL as can be seen in the documentation in the reference manual The first major difference you will probably encounter is that IF is only allowed in programming blocks The second will be the delimiter then the word go and the differences multiply from there So please don t create another SQL dialect That doesn t mean that we shouldn t iterate and improve on SQL but don t try to do something unnecessarily fancy that nobody asked for because no one will bother learning it Does My Language Solve Anything New This rule is very similar to the first one only more broadly applicable There are many databases and types of data where standard SQL can t get the job done Graph Databases are a good example of this because in their case both the storage and languages were designed specifically to do things that relational databases simply couldn t That doesn t mean that you should add to the list of well established Graph Query languages like Cypher which is already extremely popular It was created by Neoj for use with their own graph database and eventually open sourced as a separate project called openCypher which allows any database to implement the same language It s very visualーusing ASCII characters to make shapes for clean and expressive queries MATCH d Database USES gt Cypher QUERIES gt Model Graph Another widely used graph query language is SPARQL which looks like SQL and was created by the WC to query RDF graph models It s not as common as the other two languages but has unique features because of the subject predicate object data model It can even be used with SQL databases that have tables modeled after RDF structures Some graph databases also support their own languages like ArangoDB DGraph TigerGraph etc The most common graph query language at the moment would be Gremlin which is part of the Apache TinkePop graph computing framework It is simple to write easy to learn and widely supported by many graph databases and even non graph databases that can emulate graph queries On the other hand it can be verbose for long queries but generally works well for both OLTP and analysis work g V has lang gremlin out supported by values db name That being said the time is ripe for an international standard graph query language Industry vendors including Neoj and TigerGraph have called this out and I definitely agree As graphs continue to see widespread adoption we have certainly reached a tipping point for this industry and at this point you d probably be doing more harm than good by adding another language to the mix Is My Language Easy to Use If you have made it this far and your language solves a novel use case that no one has worked on before you might actually have a point by making your own query languageーthis is why the last question focuses on how you should go about it that Ask yourself How long will it take for others to learn my new language If your answer is a couple of weeks then you should start dedicating a lot of time to simplify your syntax as much as possible This doesn t just mean creating tutorials and documentation which should be self explanatory Instead this means that you will have to make a serious effort to provide processes and abstractions that let a novice pick up your language and solve your main use case in a matter of hours if not minutes If you don t think you can do that your language probably isn t ready yet ConclusionSQL is one of the most ubiquitous programming languages today but countless others deserve recognition as well These languages are often tied to specific technologies that solve use cases that relational databases simply can t However this has lead to an overproduction of query languages which has significantly slowed down development times due to steep learning curves ORMs were introduced to solve that problem but ended up complicating matters even more That is why smart developers should be wary of introducing yet another query language to the mix To guide this decision I laid out some key questions they should be asking themselves to take a good look at the existing ecosphere use cases and simplicity That being said nothing quite beats working in good ole SQL especially when you have access to a world class SQL editor like Arctype Arctype has built a collaborative SQL editor that allows you to share databases queries and dashboards with anyone easily Join our growing community and try out Arctype today	2021-07-13 15:01:13

海外TECH	Engadget	Razer’s Barracuda X wireless headset is geared toward Switch and Android players	https://www.engadget.com/razer-barracuda-x-gaming-headset-150058074.html?src=rss	Razer s Barracuda X wireless headset is geared toward Switch and Android playersBetween the enduring popularity of the Nintendo Switch the increasing power of flagship phones and new services like Apple Arcade portable gaming has finally moved to the forefront However the disappearance of mm ports on mobile devices has left many players bereft of premium audio ーBluetooth earbuds don t quite cut it when you need your audio synced perfectly If you want a rock solid connection your best bet is an RF dongle which usually uses USB A in a world steadily being overtaken by USB C ports Razer has finally stepped up with a mobile first headset that can connect to your Switch Android phone or thin and light laptop the Barracuda X The Barracuda X is far from the first headset geared toward Nintendo Switch players we re big fans of SteelSeries Arctis Wireless thanks to its comfort and superb audio quality and have even included it in a few of our gift guides It s fair to say that this headset is the Barracuda s primary competitor Even the RF adapters look the same Kris Naudus EngadgetHowever while the Arctis Wireless maintains the standard look of the line as it should ーit s a great design the Barracuda is a change of pace for Razer Instead of the Kraken brand s circular grated look the new headset resembles last year s Opus headphones which got a refresh last month It s not totally identical with different joints on the cups and cloth ear padding instead of fake leather Here in New York it s degrees as of this writing and I can report that I haven t felt the need to take off the Barracuda even after wearing it for a few hours It s still a bit warm and I definitely feel cooler when I take the headset off but it s bearable The Barracuda X also weighs a very scant grams one of the lightest headsets I ve tested I think it might be lighter than its own packaging In direct comparison it feels about the same in hand as similar models from Turtle Beach and Logitech but there s a balance in the Barracuda s plastic build that makes it feel more ethereal It s not something I would mind keeping on my head for several hours or throwing it in my backpack so I can game on the train Which is precisely the point You shouldn t feel that carrying this thing around is a burden Kris Naudus EngadgetWhile I wouldn t go tossing this thing around casually in a rage it does feel solidly built capable of taking a few dings in your bag I have mixed feelings about the detachable mic being able to take it off means a more compact headset design but it s also another fiddly bit that I might lose Then again it s unlikely you need voice functions while out and about Heck the Switch console doesn t even have real voice chat it asks you to connect via the app on your phone The Barracuda X excites me mostly because of its USB C compatibility But that s also where it falls short for me The adapter is small for sure but it s very wide That means that if you happen to have a laptop with two USB C ports next to each other like my MacBook the Barracuda dongle will block the other completely This is a hassle in my office setup where I have an external monitor and USB hub connected on the other side So while working I get to choose between the power cord and the headset I ve opted out of using the Barracuda with my laptop at all preferring instead to listen to podcasts on my phone However that s my unique situation and on the go you might only need two ports one for the headset and the other for power Kris Naudus EngadgetIt s exciting to see companies finally start to take mobile gaming seriously and address the specific needs those gamers have Mobile friendly controllers are great but many popular mobile games don t really need them Better audio though Almost everyone can appreciate that The price tag might seem a bit steep for some but the Barracuda X seems versatile enough that you ll more than get your money s worth	2021-07-13 15:00:58
