Coolify is an open-source, self-hosted platform that deploys web apps, databases, and services on your own server without the monthly bills of Heroku, Vercel, or Railway, and this guide walks through installing it on a fresh Linux server, connecting a domain, and deploying your first app with git push. Most developers pay 20 to 200 dollars a month for a platform that runs on a server they will never see, configured by a team they will never meet, on pricing that keeps going up every quarter. Coolify puts that same workflow on a 5 dollar VPS you already own, with…

A deployment goes out late at night. Everything seems fine at first. The dashboards are green, there are no alerts, and the release looks clean. A few hours later, the latency starts to increase. Nothing is critical. No alerts go off. By the time users notice, the system is already stressed. In a typical case, someone gets paged, checks the logs, reviews recent changes, and the team starts to connect the dots manually. It works, but it is slow and reactive. Now think of a different setup. The same pattern starts. Instead of waiting for things to break, an AI…
Every ML model, regardless of how it was trained or what framework built it, eventually does the same thing: it takes input and produces output. Python’s model.predict() operation is. It looks simple. It is simple-until it isn’t. The same method name appears across scikit-learn, Keras, TensorFlow, PyTorch, XGBoost, LightGBM, and most other ML frameworks. But “predict” means slightly different things in each. The return shapes differ. The input expectations differ. The performance characteristics differ. And the ways it can fail differ too. This article covers what predict() actually does, how it behaves across the major frameworks, and the practical issues…
Python makes game development surprisingly accessible. With just the standard library and a couple of small modules, you can build playable games in under 100 lines of code each. In this guide, we build three classic games step by step — a Quiz Game, Pong, and the Snake Game – using Python and the turtle graphics library. These projects reinforce core Python skills: variables, loops, conditionals, functions, and input handling. No external game engines or complex setup required. TLDR You can build fun games in Python using only the standard library — no pygame or external modules required Each game…
DevOps.com is now providing a weekly DevOps jobs report through which opportunities for DevOps professionals will be highlighted as part of an effort to better serve our audience. Our goal in these challenging economic times is to make it just that much easier for DevOps professionals to advance their careers. Of course, the pool of available DevOps talent is still relatively constrained, so when one DevOps professional takes on a new role, it tends to create opportunities for others. The 10 job postings shared this week are selected based on the company looking to hire, the vertical industry segment and…
What are some of the benefits of writing your own book? Let’s recap the basics, starting with more non-fiction oriented benefits and moving into higher-level fiction writing benefits later in this article.Benefit 1: Career Prospects 🚀 and AuthorityNot everybody respects book authors. Yet – most do:“Publishing a book is still a powerful authority signal: one survey found that 75% of people view professionals as more qualified thought leaders when they have authored a book, while broader B2B research shows that 73% of buyers trust thought leadership more than traditional marketing when judging expertise.” – ChatGPT Deep ResearchPublishing an authority book can be viewed as rocket fuel…
Coralogix and Skyflow have allied to protect sensitive log data that DevOps teams might inadvertently expose while investigating incidents or as data is shared with downstream applications. Skyflow has developed a platform that instead of eliminating or masking sensitive data applies tokens to enable that data to be searchable and auditable while preserving privacy. Coralogix CEO Ariel Assaraf said eliminating or masking data strips away context that makes it more difficult to query, correlate, and operationalize log data effectively. For example, identifiers may no longer match across events. Skyflow, via its Runtime AI Data Control Platform, applies polymorphic encryption and…
The mktemp command in Linux creates temporary files and directories with unique, unpredictable names, which is the safest way to handle scratch data inside shell scripts and system tasks. Most shell scripts you will read online create temporary files with something like /tmp/mydata.txt or /tmp/backup-$$.log, which works until two copies of the script run at the same time, or until a malicious user guesses the filename and drops a symlink in /tmp pointing to /etc/passwd. Suddenly, your harmless script is overwriting system files, and you have a real problem on your hands. The fix is mktemp, a small utility that…
One of the popular features of Redgate Monitor has been the ability to add custom mertics for various purposes. This has been popular, and along with our curated list at sqlmonitormetrics.com, it’s a feature that’s used by many.It has been a SQL Server only function for awhile, but customers have requested other platforms. We’ve added the capability for Oracle and PostgreSQL.This is part of a series of posts on Redgate Monitor.

When you are developing a user interface, it can be valuable to have a log of what’s going on. Creating a log in Textual, a text-based user interface, is even easier than creating one for wxPython or Tkinter. Why? Well, because Textual includes a logger that is compatible with Python’s own logging module, so it’s almost plug-and-play to hook it all up! You’ll learn how to do this in this short tutorial! Logging to File and the Console Textual includes a built-in logging-type handler that you can use with Python’s own logging module called TextualHandler. Python has many built-in logging handler…
