2021-04-09 13:15:40 AWS serverless patterns by Serverlessland.

Basically, this is a collection of common architecture patterns i.e. API Gateway to Lambda, Lambda and DynamoDB, API Gateway to Step Functions, etc. However, these examples also contain AWS SAM or AWS CDK templates, which you can use.

You can submit your own template as well. But no Terraform, sorry.

2021-04-05 11:59:03 Ten commandments of Go - a set of advices for better Go code.

Some of them are applicable not only for Go. Especially, number 10.

P.S. Even if your content is all right, try to avoid any religious analogies. That's just silly

2021-04-04 14:15:05 ​​strace is a very old yet popular tool for Linux troubleshooting. Moreover, on many Ops interviews an interviewer is only satisfied when a candidate mentiones strace during the troubleshooting questions section. And of course, there are more bonus points for mentioning that strace shows system calls of a given process(es) and their arguments and return values.

Although, what are we trying to solve with it? And when to use it?

Julia Evans collected 9 common categories of problems which people use to solve with strace:

- where’s the config file?
- what other files does this program depend on?
- why is this program hanging?
- is this program stuck?
- why is this program slow?
- hidden permissions errors
- what command line arguments are being used?
- why is this network connection failing?
- why does this program succeed when run one way and fail when run in another way?

P.S. She also has a free webzine on how strace works! Открыть/Комментировать

2021-04-02 12:33:07 Thinking of starting a new open source project? Or your company wants to open some internal work?

At some point you'll need to start thinking about the licenses. Taking care of it earlier helps you to avoid problems like the recent issue of Rails and mimemagic

However, you're an engineer and not a lawyer, right? Here are just a couple of resources, which can help you navigate through the differences of the Open Source licenses.

- Choose an open source license - very brief and clear guide for beginners
- TLDRLegal - another quick start guide, but contains more types of licenses

2021-03-29 13:27:39 This is not really a DevOps-ish article. However, salary topic is something that ususally interesting to everyone.

Here is an outcome of a personal research regarding salaries in the Netherlands and Europe. Personal in this case means that this research was primary driven by a private person.

I'm not familiar with dutch market personally, but overall the ideas described in this blog post are relevant to Germany as well.

Of course, things are quite different for non-EU/non-US countries. Especially, Post-soviet countries. However, it's a huge benefit that as an IT specialist you can compete not only on the local market, but also globally. Открыть/Комментировать

2021-03-28 19:12:22 A new article by Julia Evans Get better at programming by learning how things work.

It’s impossible for a single person to know everything. Especially, in such complicated systems as we have in modern IT. And it’s fine, you can still do a good job.

However, you can become even better engineer by getting down to the nature of things. Especially, when you have a tricky bug to chase.

Here are some tips from Julia on how to get there:
- Just learning a few facts can help a lot
- Connect new facts to information you already know
- Ask yes/no questions
- Googling is a skill
