Don't use VPN services.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

A Russian translation of this article can be found here, contributed by Timur Demin. There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

Why not?

Choosing a deployment tool - ansible vs puppet vs chef vs salt


  • no upfront installation/agents on remote/slave machines - ssh should be enough
  • application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
  • configuration templating
  • environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
  • deployment process run from Jenkins

View Adding Images to markdown files in Gist.markdown

How To - Upload and add Images to markdown files in Gist

Markdown files allow embedding images in it. However it requires the image to be hosted at some location and we can add the url of the image to embed it.

Example: ![Alternate image text](https://someurl/imagelocation/image.png)

We can use services like imgur or other services to host the images and use the hosted URL.
