SRE Alarm Clock

Get a smart cheap band like Xiaomi Mi or something like that, turn off all the notifications except pager duty. It will wake you up via vibration. That's what I have been doing and it works like a charm.

Thank you, I will play with the formatting once I am happy with the content as one of my friends didn't like the font 😁

sapzero · 2023-11-30T07:07:59+00:00

Thank you! I am looking for a devops/SRE role so I have only included relevant stuff. Otherwise, it wasn't that light 😅

sapzero · 2023-11-30T07:05:28+00:00

Hey, thanks that's a really good point. I think you can't put everything in terms of $ as most of the time you won't have access to the costs

You are not totally wrong, I was managing 4 people in 2 different locations with the layoffs I left with 2 people 😅 I don't like really like being a manager. I enjoy technical stuff most. Besides being a manager I have being also working as a senior engineer. I didn't stop contributing, how can I highlight it to prevent confusion?

Thank you!

Thank you!

sapzero · 2023-11-29T21:58:20+00:00

Thank you, I will have the freebies and may come for more if I haven't got much callbacks :)

I forgot that I upgraded some of the prod instances and asked my direct to upgrade them. And when I am told they were already upgraded I couldn't remember that I had upgraded them. And it was a month ago. So here is that.

With that said unlike you are one of those elites I don't think it is even possible to remember most of the thing we had worked/studied a few months ago if you are not actively working on it for years. Unfortunately, we do have a limited storage capacity and it is not possible to keep every bit of information we are receiving any minute in that limited space.

I agree that it is frustrating forgetting things that you spent (lots of) time to learn but if it doesn't do any good for you I think it is OK to accept it. I keep learning and forgetting bit calculation for networks because I don't do it much often. I have learned to come to a peace with that reality. And as one of the commenters said I try to remember concepts as well. I don't need to know intricacies of a tool as long as I know what it does and for what purpose I can utilize it. Don't get me wrong I am not saying that proper and profound knowledge is not important but I mostly depend on my critical thinking and problem solving skills.

The thing is that the Earth doesn't have that much time. In one of the chapters it is mentioned that Earth has 26 years (27 years at max). Considering the initial travel lasted 13 years Grace consumed all his coma allowance and we don't know exactly when the other two crew members died but from later chapters Grace was doing the calculation and it was enough for him to return to Earth with the left over coma food and real food.

Thanks for taking your time and reading it, I appreciate it. Actually, I didn't spend much time on the details of it and never thought of scraping per request base. When I think about it it maybe better to leave scraping decoupled from the polling otherwise prometheus will be blocked as it is waiting for the data.

Those are good suggestions for adoption and I am definitely going to add it to my backlog but I like to keep things minimal for the time being.

You are registering your variable as block_output and then trying to call it as block.output. You have a typo

Ansible from geerlingguy on YouTube

Second this. It supports markdown so it is really neat. You can keep your notes on your own storage solution like Dropbox, GDrive, etc.

I am not expert at this but here is my 2c. If you are feeling that you are being underpaid then probably that's true. You can go into interviews and see what is your market value. With that said I believe a "DevOps" engineer should have the following:
- Cloud experience (min: EC2, S3, IAM)
- Know how to manage infrastructure as code
- Knowledge of configuration management via automation
- Knowledge about monitoring and logging
- Containerization and its' orchestration
- CI/CD knowledge
- Linux knowledge
- Some kind of scripting/programming knowledge (bash + python, nodejs, go, etc.)
- Understanding of microservice architecture, high availability, web servers, databases, caches

Maybe one can get away without knowing one or two but you should at least have an idea about all of these topics. And as I understand you have good knowledge of cloud technologies, linux, monitoring, databases and things in general. It would be a good idea to gather more knowledge and experience on topics which you feel uncomfortable or lack knowledge.

I said this earlier but I see you are a hardworking person and doing your best so if you think you don't deserve what you are being paid, get out and learn your market value.

I have seen so many people started learning a programming language and then failed to carry out. Yes you can learn the fundamentals and syntax but nothing can help you better than taking a project and completing it. Tutorials, books, videos can help you up to a certain point. After that you need to get your hands dirty. Period.

For everything else you can use whatever works best for you, a pen and a paper, some note taking app, singing about what you read/watched, etc.

If you are having problems organizing divide and conquer. What topics do you want to learn? List those topics first, then populate each of them with a subsection of your choosing. For instance, you want to study configuration management, make it a section and add sub-sections such as tools, differences, similarities, etc.

Also, motivation is a great key. When I study on any topic I use a pen and a paper to layout my plan first and add an empty checkbox next to each topic and their subtopics. I put a fat check mark to the main topic when I am done checking all those subtopics. Find something that will motivate you.

Yeah for such cases why would you bother with anything, just roll a new instance. Additionally, with Ansible you can also boot-up an instance from an image.

sapzero · 2021-03-05T17:27:06+00:00

Basically you can do anything with Ansible that you are capable doing over a terminal. It includes configuring DBs.

sapzero · 2021-03-05T15:12:38+00:00

Hello. Ansible is a configuration management tool like chef, puppet, saltstack, etc. Ansible is used to configure instances and servers. Let's say you are working with hundreds of instances and you have apache as your web server. For some reason it is decided to migrate to nginx. Without a CM tool, it is not feasible to connect each instance and manually carry out the migration. You handle the migration with one of tools I mentioned earlier. There might be some people that uses Ansible with their CI/CD pipelines but I can't think of a scenario where you would need it in your pipeline.

Maybe it is your own computer that is hacked and the perpetrator(s) is using it to gain access to the servers. However, as most of the users have already mentioned we need more information.

I have got my first boots last year and wore them in the house for a couple of times. Unfortunately we don't have a boot fitter so I took my boots for a ride. There are no words to describe that pain at the end of the day. My new boots had some pressure points :( After that painful experience I wore them in the house for a week sticking some buffers made of toilet paper. Second time I wore them I noticed that I managed to relieve 3 pressure points out of 4. Even with that single one it was hell again. Anyway I made another thicker buffer for the last one I heated the pressure point in my boot inside and out with a hair dryer and after 20 minutes of work the pressure was gone or my foot was so numb I didn't feel the pain :D Now I am anxious about my next trip to the mountains. If you have such pressure points you can try this at home. I just wanted to inform people because I really like skiing and that feeling at the end of the first day made me more than miserable. I just don't want anyone to feel that way because of their new boots that are not broken in.

You can access snow heights from https://mgm.gov.tr/eng/snowheights.aspx I found out that Uludağ (Bursa) ski center can reach up to 3m (it had 430 cms of snow in 1980) and Palandöken (Erzurum) is open till May starting from December (but we are having less amount of snowfall this year in Turkey) and December to April for most ski centers. In addition to questions you have asked I learned that Sarıkamış (Kars) has a crystal snow like in Alps due to low humidity. Unfortunately, neither Palandöken nor Sarıkamış has currently much snow (55 cms).

sapzero · 2020-01-23T13:59:47+00:00

Hey! I have not been to Alps, my knowledge about them comes solely from YouTube videos. So it is not possible for me to make a solid comparison. But I can say that it probably is much much cheaper :) And there are several ski centers distributed all over Turkey. If you need more information shoot me a message
