Any good online text editors?

I'm getting so lazy I don't even want to have to open an application for basic text editing :) Something that loads up from a link without logging in and has basic find and replace, maybe line join and even regex find and replace.

I have been using https://onlinenotepad.org/ but I wondered if there was something that offers slightly more functionality and doesn't look like it was made in 2003.

Elite vs. Low Performing DevOps Teams: How good is your DevOps team?

How good is your DevOps team? You can find out where you stand on the software delivery performance scale - elite, low performing, or somewhere in between. Vote below, and let's see where we all stand. Let's together have an open discussion about the #DORA Metrics. Let's see if these metrics actually empower and enable our DevOps teams or are these metrics just BS, easily manipulatable KPI's for micromanaging teams or is this just good old marketing tricks.

Here's the \#google #DORA Report!

Multicluster Prometheus question

Hello everybody.

I'm in the process of moving our projects from VM to k8s. In our new k8s setup we want to implement multi-cluster, multi-cloud infrastructure. So far, so good. Everything seems understandable and reasonable, except monitoring.

I have never used Prometheus before. Our company used TIG stack with VMs, which we found reliable and easy to use.

So, we need to collect metrics from both clusters. As far as I understood, we need to setup some external service to collect those metrics. I found info about different agents, Telegraf Prometheus plugin, Thanos, Prometheus Federation, etc. But I don't understand, why we can't just connect Prometheus services as backends to Grafana and collect metrics without proxy services? I know that Prometheus is stateful app, so if it goes down, historical data could be lost. For us it is not a big deal, because all necessary metrics we collect and store in external ELK stack.

So what are cons of using Prometheus connected directly to Grafana?

git: 'submodule' is not a git command ONLY when running through Jenkins

I am adding a Windows worker to my Jenkins instance but hitting some issues with Git, this issue occurs when using checkout scm in the pipeline or putting git submodule into a bat block.

I can run any other git command just fine, I can run it as the fully qualified executable path or just git with the same results as well.

Running git --version outputs the same version number and I updated from 2.30 to 2.40 without resolving the issue, but both git --version outputs changed so I think I am 100% running the correct git binary via Jenkins.

I have no clue why or how this issue could be occuring, any insight would be appreciated.

When run via Jenkins:

C:\Jenkins_Workspace\workspace>"C:\Program Files\Git\cmd\git.exe" submodule 
git: 'submodule' is not a git command. See 'git --help'.

When run on the host:

C:\Jenkins_Workspace\workspace>"C:\Program Files\Git\cmd\git.exe" submodule
<listed module here>

Become your own heru?

Hi all! So we've created a platform that enables connecting to any registry, any vm you have and easily deploy infinite Docker apps while connecting each app to a domain. Oh, and we do all the hard wiring without installing any agents! are looking for first users to help validate it.

Job hunt advice

I am a Master's student who is working as a DevOps engineer at a startup.

I will be looking for a full-time job (DevOps, SRE, Platform engineering) later in the year.

Just wanted inputs on how to look for the above-mentioned jobs. Should I just use job platforms like Indeed or Linkedin? Are there any other techniques that worked particularly well for you apart from applying to job websites?

Thanks.

PS: I am doing my masters in Canada.

Designing architecture for containers where every container is unique in ECS

Hey Devops, been tasked with designing a solution for a containerized application where each container must maintain a 24/7 TLS connection with an endpoint, and having some difficulty thinking through this.

We're migrating what is normally a single container hosted on-prem by the customer to a cloud solution hosted by us. It's my understanding that each container is running the same application but is facilitating a custom integration interface and needs to have access to a set of certificates specific to the customer for outbound traffic. I also need to route to a particular container based on inbound IP.

My difficulty is understanding how to make this scalable. From what I've gathered there is a single task or workload ongoing by each container so these wouldn't(?) be clustered together. It sounds like I would need a unique task definition per customer so we can connect them to the proper volume. We don't really need to scale the amount of containers per customer, but internally we need to be able to scale to however many customers we onboard.

Currently my line of thinking is that we're just going to have a task definition per customer and set an ALB in front to route. Is there a better way to do this that I'm missing?

I'm working out how to handle this and reduce the manual configuration and technical load as best I can. Part of me feels like this might be best suited to just being VMs.

Framework for tool development?

I’m not sure how many of you have cause to develop internal tools, but for those who do what framework are you using? I’ve seen some people using Retool, but it seems somewhat limited in scope. Has anyone ever delved into using something like React for this?

IAM application control security Interview question

Today I had an interview at a big trading firm for cloud dev sec position and one of the questions that I couldn't seem to answer was " how would you implement or design IAM application control if an application needs to use resources from another application or if a user needs to use resources to another application."

I gave the short hand answer of RBAC or ABAC and or MFA and or grant the user the access to the resources. But the interviewer had a really shitty mic and i could barely hear him. Can someone who has experience on this tell me what i should read or guide me in the right direction. I've already tried chatgpt and it gave me very vague answers.

Need Help With Some Perforce Commands

Hey there!

I'm hoping this is the right place to ask these questions, but I'm a game developer using Unreal Engine and Perforce as our source control. I'm having some issues with retaining server space, as our project files are constantly being modified and updated on our Perforce server, and file sizes are snowballing as individual files can have 50-100 revisions.

It's my fault for not tackling this issue earlier, I now know that it is possible to limit how many revisions a file can have with the +sN modifier of the filetype command, but as far as I can tell, this is per file, and would need to be done on each new file added to the repository. Is there a way to set this to automatically be done for every new file? Unreal Engine has their .uasset file type which most project files are stored as, If I was able to tell Perforce to only keep the last 5 revisions of every .uasset file, then that would solve most of my problems.

My next issue is one that I'm not sure there is a solution to, but I'm currently going through our depot in P4Admin and finding files which have huge amounts of revisions and deleting the earlier revisions one by one. And again, I know this is my fault for not setting things up right in the first place, but is there any way through either P4V or the Command Client to select a folder and remove all revisions of every file in the folder except for the head revision?

This would be very helpful as in some of the worst cases in our depot, the total size of just the head revision files can equal around 500mb, but in reality with all of the different revisions of all the different files, the size jumps up to around 10gb!

Thanks in advance for any insight into these issues!

BEST BIG LIST OF FREE OPEN PUBLIC APIS



Are you looking for some free and open public APIs that you can use for testing, learning, or building your own apps? If so, you’re in luck. There are many APIs out there that offer a variety of data and services without requiring any authentication or key. In this article, we’ll introduce you to some of the best ones and show you how to access them.

📷

## What is an API?

An API (Application Programming Interface) is a way for different software applications to communicate with each other. An API defines how a client (such as a web browser, a mobile app, or a spreadsheet) can request data or services from a server (such as a website, a database, or a cloud service).

For example, when you use a weather app on your phone, the app sends an API request to a weather service provider (such as Weather.com) and receives an API response with the current weather data. The app then displays the data in a user-friendly format on your screen.

APIs are useful because they allow developers to access and use data and services from other sources without having to create them from scratch. They also enable interoperability and integration between different applications and platforms.

## What is a free and open public API?

A free and open public API is an API that anyone can access and use without any restrictions or requirements. You don’t need to register, sign up, or obtain an API key to use these APIs. You just need to know the URL (Uniform Resource Locator) of the API endpoint and the parameters (if any) that you need to specify in your request.

Free and open public APIs are great for beginners who want to learn how APIs work and practice their skills. They are also helpful for web developers who want to test their code or prototype their ideas with real data. And they are fun for anyone who wants to explore different types of data and services available on the web.

## How to use free and open public APIs?

There are many ways to use free and open public APIs depending on your needs and preferences. Here are some common methods:

* Web browser: You can simply type or paste the URL of the API endpoint in your web browser’s address bar and hit enter. You will see the API response in JSON (JavaScript Object Notation) format, which is a standard way of representing data in APIs. JSON is easy to read and parse by humans and machines.
* Coding language: You can use any modern coding language (such as Python, JavaScript, Ruby, etc.) that supports HTTP requests to send an API request and receive an API response. You will need to write some code to handle the request parameters, headers, errors, etc., as well as parse and process the JSON response.
* cURL: You can use cURL, which is a command-line tool for transferring data using various protocols (such as HTTP), to send an API request and receive an API response. You will need to type some commands in your terminal or console window with the appropriate options and flags.
* No-code API clients: You can use no-code API clients, which are graphical user interface (GUI) tools that allow you to interact with APIs without writing any code. Some examples are Swagger UI, Postman, Insomnia, etc. These tools let you enter the URL of the API endpoint and the parameters (if any) in a form-like interface and display the JSON response in a formatted way. They also provide features such as documentation, testing, debugging, etc.
* Google Sheets: You can use Google Sheets, which is a cloud-based spreadsheet application that supports custom functions written in JavaScript using Google Apps Script. One of these custom functions is IMPORTJSON(), which allows you to import JSON data from any URL into your spreadsheet cells. You can also use Apipheny, which is an add-on for Google Sheets that lets you connect any API to Google Sheets without coding.

## Best Big List of Free Open Public APIs

To help you get started with using free open public APIs, we have compiled a list of some of the most useful, fun, and interesting ones that you can try out right now. We

have categorized them by topic and provided sample URLs for each one. You can click on these URLs to see the JSON responses or copy them to use them with your preferred method.

Am I A Software Developer?

I don't know myself for sure . So, let me ask.

If i am using python to create automation tools for my department, like web scrap(from AWS) ,download raw data ( about 200K rows/file), process raw into structured data and create a summerized data report as an excel output. Since the users are non techies, i had to use simple GUI for accessible UX. My program as whole consists of 12 modules and refactored and made reusable pieces as much as i can. Can i call myself Software Engineer.
Tools I used -- > python, tkinter, pandas, numpy, Selenium, git

Who are some people you follow and stay up-to-date with?

I got a habit of bookmarking and highlighting everything with any kind of worth.
All my bookmarks get pushed into Readwise Reader and all kindle or browser highlights get imported into Readwise itself, which is configured to send everything to Obsidian for later use.

Mostly I read books or docs, sometimes I read blogs to find solutions for problems... but I'm searching for a way to always stay up-to-date and on the edge... so...

The Best Networking DevOps Course

Which DevOps Networking course is the most ideal for a Network Engineer with an A+ and 3 years of experience? I have looked and Juniper and Cisco courses. The Cisco course seems to have a lot of resources including an Udemy course which I found quite useful.

What are your thoughts? Is there a vendor-neutral Networking DevOps Course?
