Google recently released its own code editor, Antigravity. Based on Microsoft’s Visual Studio Code, Antigravity brings a lot to the table. I’ve been using it for the past few weeks, and here’s why I think it should be your IDE of choice.
Have you ever stared at a large directory of file names and dreaded the idea of renaming them all? Or perhaps your scripts are littered with conditional statements checking to see if an environment variable exists. Bash provides a concise syntax for changing strings that makes life easier. They're called parameter expansions, and I'll show you how to use them.
Cross-browser extensions are easy to write, thanks to the WebExtension initiative and core Web technologies. Using a common format, you can write extensions that work anywhere, without the need to target specific browsers.

It might be hard to imagine now, but not too long ago the idea of free software with source code that anyone can modify wasn't one with much enthusiasm behind it. How could that be safe? What about support? Could you trust mission-critical stuff to this software?

With the popularity of AI coding tools rising among some software developers, their adoption has begun to touch every aspect of the process, including human developers using the tools to improve existing AI coding tools. We’re not talking about runaway self-improvement here; just people using tools to improve the tools themselves.
In interviews with Ars Technica this week, OpenAI employees revealed the extent to which the company now relies on its own AI coding agent, Codex, to build and improve the development tool. “I think the vast majority of Codex is built by Codex, so it’s almost entirely just being used to improve itself,” said Alexander Embiricos, product lead for Codex at OpenAI, in a conversation on Tuesday. Codex now generates most of the code that OpenAI developers use to improve the tool itself.
Codex, which OpenAI launched in its modern incarnation as a research preview in May 2025, operates as a cloud-based software engineering agent that can handle tasks like writing features, fixing bugs, and proposing pull requests. The tool runs in sandboxed environments linked to a user’s code repository and can execute multiple tasks in parallel. OpenAI offers Codex through ChatGPT’s web interface, a command-line interface (CLI), and IDE extensions for VS Code, Cursor, and Windsurf.

Side projects usually seem like a hobby, but they can be the most powerful career launchpad available. While traditional metrics like university degrees and years of professional experience still hold weight, a well-executed side project acts as a direct, unfiltered view of your technical capabilities, your problem-solving approach, and your passion for creation.
On Tuesday, French AI startup Mistral AI released Devstral 2, a 123 billion parameter open-weights coding model designed to work as part of an autonomous software engineering agent. The model achieves a 72.2 percent score on SWE-bench Verified, a benchmark that attempts to test whether AI systems can solve real GitHub issues, putting it among the top-performing open-weights models.
Perhaps more notably, Mistral didn’t just release an AI model, it released a new development app called Mistral Vibe. It’s a command line interface (CLI) similar to Claude Code, OpenAI Codex, and Gemini CLI that lets developers interact with the Devstral models directly in their terminal. The tool can scan file structures and Git status to maintain context across an entire project, make changes across multiple files, and execute shell commands autonomously. Mistral released the CLI under the Apache 2.0 license.
It’s always wise to take AI benchmarks with a large grain of salt, but we’ve heard from employees of the big AI companies that they pay very close attention to how well models do on SWE-bench Verified, which presents AI models with 500 real software engineering problems pulled from GitHub issues in popular Python repositories. The AI must read the issue description, navigate the codebase, and generate a working patch that passes unit tests. While some AI researchers have noted that around 90 percent of the tasks in the benchmark test relatively simple bug fixes that experienced engineers could complete in under an hour, it’s one of the few standardized ways to compare coding models.

Visual Studio Code just released its November 2025 update, version 1.107. There are more improvements for AI coding agents and TypeScript support, but I'm mostly excited about another change: a much more powerful terminal.
You may have noticed people discussing GitHub alternatives recently. In particular, several projects have migrated to a competitor called Codeberg. Having investigated further, I’m convinced it’s a solid alternative, and it’s not the only one.
In Microsoft Excel, you can convert your data into many types of charts. However, frustratingly, there's no option for a standard timeline chart. To get over this hurdle, I use a basic line chart to create a dynamic, professional timeline in 10 minutes. Here's how you can too.
Python is one of the most popular languages for developing AI and computer vision projects. With the power of OpenCV and face detection libraries, you can build smart systems that can make decisions and accomplish tasks. Let's build a system that sends an alert upon detecting a face.
Thirty years ago today, Netscape Communications and Sun Microsystems issued a joint press release announcing JavaScript, an object scripting language designed for creating interactive web applications. The language emerged from a frantic 10-day sprint at pioneering browser company Netscape, where engineer Brendan Eich hacked together a working internal prototype during May 1995.
While the JavaScript language didn’t ship publicly until that September and didn’t reach a 1.0 release until March 1996, the descendants of Eich’s initial 10-day hack now run on approximately 98.9 percent of all websites with client-side code, making JavaScript the dominant programming language of the web. It’s wildly popular; beyond the browser, JavaScript powers server backends, mobile apps, desktop software, and even some embedded systems. According to several surveys, JavaScript consistently ranks among the most widely used programming languages in the world.
In crafting JavaScript, Netscape wanted a scripting language that could make webpages interactive, something lightweight that would appeal to web designers and non-professional programmers. Eich drew from several influences: The syntax looked like a trendy new programming language called Java to satisfy Netscape management, but its guts borrowed concepts from Scheme, a language Eich admired, and Self, which contributed JavaScript’s prototype-based object model.

sudo qemu-img convert -p -f qcow2 -O raw "$SOURCE_QCOW2" "$LV_PATH")This took me a few days to figure out, but now the cloned guest has the correct disk size. I can now easily clone the template and customize it for specific server configurations. (I skipped over the steps related to editing the KVM's xml for the new server or using virsh to activate the new cloned image -- because that would be an entire blog post all by itself.)# Create the new server's disk space

ssh prodserver "cd / ; sudo tar -cf - home" | (cd / ; sudo tar -xvf - )On the receiving server:The rsync solution would be simple and elegant. In contrast, using tar and netcat is a really ugly workaround -- but it works. Keep in mind, the netcat tunnel is not encrypted. However, I'm not worried about someone in my internal network sniffing the traffic. If you have that concern, then you need to establish an encrypted tunnel. The catch here is that ssh does not transfer the tar stream -- the tar stream comes over a parallel connection.
cd / ; nc -l 12345 | tar -xvf -This waits for a connection on port 12345 and sends the data to tar to extract. netcat will terminate when the stream ends.
To get to the production server:
ssh -o LogLevel=error -t "$OldServer" "cd / ; sudo bash -c 'echo Running as sudo' ; sudo tar -cf - $GetPathsReal | nc newserver 12345
This is a little more complicated:
- "-o LogLevel=error" My production ssh server displays a banner upon connection. I need to hide that banner so it doesn't confuse tar.
- "-t" opens a terminal, so sudo will prompt for a password.
- "sudo bash -c 'echo Running as sudo'" Get the sudo prompt out of the way. It must be done before the tar command. This way, the next sudo call won't prompt for a password.
- "sudo tar -cf - $GetPathsReal | nc newserver 12345" This tars up the files that need to be transferred and sends them through a netcat tunnel.
