Gems can save you a lot of work, help you clean your code, and avoid security issues, so use them wisely! You can find it here. The isolator gem can help with this. All you have to do is install the gem, then when it detects a bad transaction it will raise an exception. But there are tools to help you find why your tests are slow so you can fix them!

Building a Ruby Project

One gem that can help you with this is attractor. It produces an HTML report, and a list of high-churn files that you can use to focus on your efforts. These are great!

Looking forward to checking them out. Share this post! What are the best Ruby gems that you can use in your Rails projects? But before we do that… A warning.

If it remotely sounds like it could be helpful. If your image needs to install any additional packages beyond what comes with the image, you'll likely want to specify one of these explicitly to minimize breakage when there are new releases of Debian. This tag is based off of buildpack-deps.

It, by design, has a large number of extremely common Debian packages. This reduces the number of packages that images that derive from it need to install, thus reducing the overall size of all images on your system.

Fall Specials

This image does not contain the common packages contained in the default tag and only contains the minimal packages needed to run ruby. Unless you are working in an environment where only the ruby image will be deployed and you have space constraints, we highly recommend using the default image of this repository. This image is based on the popular Alpine Linux project , available in the alpine official image.

This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends , so certain software might run into issues depending on the depth of their libc requirements.

However, most software doesn't have an issue with this, so this variant is usually a very safe choice. To minimize image size, it's uncommon for additional related tools such as git or bash to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile see the alpine image description for examples of how to install packages if you are unfamiliar.

As with all Docker images, these likely also contain other software which may be under other licenses such as Bash, etc from the base distribution, along with any direct or indirect dependencies of the primary software being contained. The project was called Chef Sugar, a Ruby library for simplifying work with Chef , a platform for configuration management.

Varga developed and open-sourced the library while he worked at Chef, and the library was later integrated into Chef's source code. The news didn't go well with Vargo, who, yesterday, September 19, took down the Chef Sugar library from both GitHub and RubyGems, the main Ruby package repository, in a sign of protest.

Vargo's actions didn't go unnoticed, and in a blog post published later in the day, Chef Software CEO Barry Crist said the incident impacted "production systems for a number of our customers. The Chef team fixed the issue by scouring some of the older Chef Sugar source code and re-uploading it on their own GitHub account. However, things didn't stop here. Vargo's unique method of protesting the ICE's treatment of children went viral on social media. Many developers stood by his decision, even if they, too, had to find replacements for the Chef Sugar library in their own projects [ there's one here ].

You've made my job harder today, but I really don't mind. I'm so proud of sethvargo today, who removed his code from the Chef ecosystem after they entered into a contract with ICE. How absolutely despicable. I would leave.

Over the course of the past day, Chef engineers and leadership have been bombarded with requests to drop out of the ICE contract and criticism for signing it in the first place. The pressure didn't come only from the outside, but also from within Chef. The company's CEO responded with an email sent to all employees, later also published on the company's blog.

Crist said Chef had been a long-time ICE collaborator for years, since the previous administration, long before the ICE become the hated agency it is today. I do not believe that it is appropriate, practical, or within our mission to examine specific government projects with the purpose of selecting which U. The Chef CEO did add that he didn't agree with the ICE's practices of separating families and detaining children, but that "Chef as a company that transcends numerous U. I get that the whole Chef - ICE thing is legitimately causing issues for some people in regards to moral and ethical decisions.
