My curiosity is finally out of control, it's time to try the server Swift!I don't have any back-end programming experience in addition to using a few Baas, but fortunately the open source community has already provided a ready-made Framework. I tried the Vapor framework that Tanner N

Yii scheduler jobs Original English/Scheduling Jobs With Yii Sometimes there will be a long running or a lot of computing work in your application. we should not let users wait for the server to process them, but let them process them in the background. you may need to perform some operations very late, such as sending a user report at the end of a day. the solution to the preceding scenario is to create a queue and process it on a non-web client.Heroku scheduler

Node. js may still be younger than other languages, but its VM has many options. In this article, let's take a look at several "Platform as a service (PaaS)" providers. I do not cover certain infrastructure-as-a-service (IaaS) options, such as AWS and Joyent, although the boundaries between some PaaS and IaaS in these options are slightly blurred. In this round, I mainly examine two aspects: Deployment and environment variable configuration. I also included some observations on the dashboard and

allocate, the more work the Ruby GC (Ruby's garbage collection mechanism) needs to do. Rails is already taking up a lot of memory, and the average application is just starting to consume nearly 100M of RAM. If you are not aware of the memory control, your program memory growth over 1G is very possible. So much memory needs to be recycled that it's no wonder that most of the time the program executes is consumed by the GC. 2 How do we make a Rails application run faster? There are three ways t

simple chatbot that can retrieve information or provide notifications whenever GitHub has code to submit, question, or activity. In a team designed to reduce or even completely eliminate meetings, hubot has chat interfaces for all team members, helping you record every discussion. This certainly promotes flexible work schedules because the team does not have to attend the discussion at the same time. Warning: hubot is very addictive! With this, let's start setting up a hubot on

dependenciesIt's a good practice to stick with--save (or--save-dev) when installing a module locally on a project. These options add the specified module to the Package.json dependencies (or devdependencies) manifest and use a reasonable default semver range.NPM Install Domready--saveNote that NPM now uses the Semver range of the caret style:"Dependencies": { "Domready": "^1.0.4"}3. Specify the startup scriptBy setting the Scripts.start in Package.json, you can start the program with NPM start

In fact, I'm trying to build a lot of smaller websites to get some of the negative income (not tax revenue) that is satisfying. (Anyway this is my goal) to this end, I launched my first unnamed web site yesterday. Unfortunately, because it is a project that needs to be paid for by myself and I need to build a lot of sites, I have t

more memory you allocate, the more work Ruby GC (Ruby's garbage collection mechanism) needs to do. Rails occupies a large amount of memory, and each application occupies nearly 100 MB of memory after it is started on average. If you do not pay attention to memory control, it is very likely that your program memory will grow by more than 1 GB. So much memory needs to be recycled, it's no wonder that most of the execution time is occupied by GC. 2. How can we make a Rails application run faster?

to implement. Heroku basically does this for you, while Hirefire makes this process more automated. You can learn more about automatic resizing here. Other hosting environments provide similar solutions. In short, you can use it. However, please note that resizing is not a silver bullet that improves performance. If your application only needs to respond to a request within five minutes, resizing is useless. In addition, using
