Topic: "Docker + GPU. Not about mining."

Anna Shcherbinina

Just before Christmas we launched a new body-measurement feature for our shapify.me project. A person goes into the 3D booth, gets scanned, and the body-measurements are calculated with the 3D scan data. We couldn't avoid using a GPU with these calculations.

How to install this branch of processing into our elegant scaling pipeline? When you're dealing with 3D scans you should remember two things: it's expensive and time-consuming. By the way, its workload fluctuates throughout the days. The easiest solution for us was to use Docker.

This speech is not about mining, but the most helpful articles for us were ones such as "Building your own mining farm". That's because we use quite a similar infrastructure.

GPU, Docker, scaling. What we achieved, where we failed, and what it became of it in the end is all included in my speech.

Topic: "A polyglot's view of Ruby on Rails"

Leonid Shevtsov

Nowadays, it's hip to switch from Rails to other languages and frameworks. Leonid, too, has abandoned Rails, played the field a bit, and has come around to occasionally but consistently picking Rails for some projects. What's the modern reason to use Rails? What are the strengths of Ruby and Rails and how to build upon them? When you should really jump to some other platform? Let's answer these questions in a true Ruby meditation.

Topic: "Project development - preparing hell dish together"

The recipe is averaged, because of many variations. We take some Ruby code and add Rails magic, Postgresql on top. Add Docker for viscosity. Then put this on AWS EBS pan and start frying. It's all roasted until burning deadlines and generously watered with bugs, serves to the customer. They start eating. Eat and whisper: “This is an awesome product!”. At the same time, he forehead is sweating. Kindly offer to fix bugs, but we refuse and put them in JIRA. Do I need to talk about what kind of feedback comes then? Tasks with such recipes, that double estimated.

RubyMine 2018.2 to be Released

Great news for Ruby developers - new version of popular IDE available now
27 July 2018   199

Major summer update of the integrated development environment RubyMine from JetBrains under the number 2018.2 released. Among the innovations - improving the work with the code, support for new version managers, re-testing only for failed tests and much more.

Code analysis

The new version of IDE has received an improved type inference that allows to better read the types of elements in blocks, arrays and hashes. This feature improves code autocompletion and navigation throughout the project:

Element CompletionElement Completion

In addition, RubyMine now correctly recognizes models using polymorphic associations, and offers them full support for "smart" functions.

Version Managers

The updated development environment now supports chruby and asdf. Moreover, now all version managers are available in WSL, Docker, SSH and other remote connections.

Testing

RubyMine 2018.2 allows you to retest only those tests that have not been tested. According to the developers, this frees the user from manually viewing each failed check. The new function also works with the rake test and rake spec presets:

Rerun Failed Tests

YAML

In this update, developers paid attention to the YAML data serialization format. Now its code can be formatted directly in the IDE and use all the functions of autocomplete and navigation by code. Moreover, the new version of RubyMine provides automatic filling of YAML data structures that have JSON Schema files, and the ability to copy / paste the key path to the value in .yml files.

Git

Support for version control in RubyMine 2018.2 has received several new features:

  • files with a merge conflict are now grouped in a separate node;
  • a new action Browse Repository at Revision allows you to examine the state of the repository after each revision;
  • It was possible to skip the Push action during the Commit and Push command or use it only for protected branches;
  • you can connect an unlimited number of accounts to GitHub and select the main one for each project.

Other improvements

In addition to general performance improvements, the new version of IDE brought new icons, a dark theme for MacOS, support for the Touch Bar, improved support for JS, TypeScript and CoffeeScript, which you can see in the overview of the WebStorm 2018.2 IDE update, and connect the debugger to remote processes without having to reboot .
