Quick Answer: nproc limits control the maximum number of processes/threads a user can create (default: 1024–4096), while nofile limits restrict the maximum number of open file descriptors per process (default: 1024). Both are critical Linux resource limits that prevent system overload and ensure stability. Configure them via /etc/security/limits.conf or systemd service files. Every Linux system […]

Since I started learning about computers, I have heard many experienced users say Linux is impenetrable, Linux offers the best security, and so on. It is partly true that Linux offers various security measures that mitigate attacks and stop hackers from breaching your system network. However, you should also understand that simply deploying Linux on […]

When managing network security on Linux systems, understanding the distinction between a firewall and firewalld is quite vital for effective system administration. While these terms might sound similar, they represent fundamentally different concepts in the Linux security ecosystem. A firewall is a broad term referring to any network security system—whether software or hardware—that monitors and […]

Visual Studio Code 1.104, the August release of Microsoft’s code editor, was released few days ago.

The new release introduced Auto AI model selection support (Preview feature), allowing to automatically choose between Claude Sonnet 4, GPT-5, GPT-5 mini, and GPT-4.1 models, to get the optimal performance and reduce rate limits.

And, user can view the selected model and the model multiplier by hovering over the response in the Chat view.

In agent mode, the agent now explicitly asks for user confirmation before making edits to certain files. And you can configure file patterns to indicate which files require confirmation with chat.tools.edits.autoApprove setting.

The release also improved GitHub coding agent integration with chat editor actions, seamless transitions, better session rendering, and performance boosts. And, it enhanced chat sessions view with status bar tracking, multi-session support, rich descriptions, and expanded context menus.

The #codebase tool has been updated to use a new embeddings model for semantic searching for code in workspace, providing better results, while using less storage space (only 6% compare to previous model).

Other AI changes in VS Code 1.104 include:

• Support for AGENTS.md files (Experimental).
• Use custom chat mode in prompt file.
• Support changing font family and font size of chat messages.
• Sign in or sign up to GitHub Copilot with Google account is GA.
• Add warning first time to enable global auto approve.
• New setting for disabling and hiding GitHub Copilot AI features.
• Add more terminal tools to core.
• Math rendering in chat responses is GA and enabled by default.
• Enhance terminal auto-approve usability and security.
• Enable or disable each tool individually.

Besides AI changes, the release also added support configuring the color of window borders in Windows. User can choose to respect color theme settings, Windows settings, disable border colors, and a specific color in Hex, RGB, RGBA, HSL, HSLA format.

It added Accounts: Manage Extension Account Preferences command to the Command Palette, new setting to show tab index, ability to toggle editor tab bar scoll-bar visibility, as well as new “Ceate on GitHub” and “Preview on Github” buttons in built-in issue reporter.

The code editor can now reads and includes MCP server instructions in base prompt. It includes new setting options to allow all MCP servers or disable MCP entirely. And, it now disables MCP auto discovery by default.

As well, it improved NES suggestion by adding new setting to allow the language model to access the entire notebook, thus it will generate more accurate and higher-quality next edit suggestions.

Other changes include:

• add Focus Chat Confirmation action.
• new setting to configure how quickly inline suggesstions appear after you type.
• add “Compare with Workspace” context menu option for worktree file, and Migrate Worktree Changes… command
• remove the built-in bower.json IntelliSense
• add Python Environments extension support for Pipenv
• new experimental AI hover summaries for Python with latest Pylance.
• Pylance IntelliSense enabled in all Python documents
• finalized Language Model Chat Provider API
• And much more!

For user with NVIDIA graphics card, Ubuntu finally added official NVIDIA 580 driver packages for all current Ubuntu releases.

As you may know, NVIDIA 580 is so far the latest driver series for Linux, that was initially released one month ago. It’s a production branch driver qualified for enterprise and data center GPU use.

The 580 driver features Wayland fifo-v1 protocol support for apps/games running via Vulkan API, reducing visual inconsistencies and potential stuttering.

It enabled RMIntrLockingMode feature by default, which can help reduce stutter especially when using virtual reality (VR). As well, it implemented a feature to reduce time spent in the interrupt top half for low latency display interrupts by deferring the work until later. See HERE for more.

With NVIDIA 580.82.07, it also supports NVIDIA Smooth Motion on GeForce RTX 40 Series GPUs!

Install NVIDIA 580 driver in Ubuntu

Ubuntu made NVIDIA 580 driver (so far 580.65.06) package into the proposed repository for testing few weeks ago. Now, it finally goes official. And, you may install it by following steps.

1. Enable Restricted and Multi-verse repository

The proprietary driver is available through the restricted and multiverse repositories. They are usually enabled by default in Ubuntu desktop.

Just in case, you may launch “Software & Updates” utility to ensure:

Or, run the command below for Ubuntu Server to enable them:

sudo add-apt-repository restricted multiverse

You need to install software-properties-common package if the command does not work.

2. Update your system.

Before installing the driver, it’s better to install all available system updates, especially kernel updates (usually minor version updates), to prevent potential failure.

To do so, either use Software Updater or run the commands below in terminal (Ctrl+Alt+T):

sudo apt update

sudo apt upgrade

If there’s a kernel updates, restart computer to boot the new kernel.

3. Install NVIDIA 580 driver

NOTE: The driver version so far is nvidia 580.65.06. If you can’t wait to get 580.82.07 for NVIDIA Smooth Motion support on RTX 40 series GPUs, or you’re on old Ubuntu 20.04|18.04, then run command below to add the popular “Graphics Drivers” team PPA, which however is not officially supported.

sudo add-apt-repository ppa:graphics-drivers/ppa

For Ubuntu Desktop, you may now launch “Additional Drivers” utility, then select either driver below:

• nvidia-driver-580 for general desktop and gaming purpose.
• nvidia-driver-580-server for Ubuntu Server or computing purpose.

Then, click “Apply Changes” and  restart computer when installation done!

For server without GUI, simply run the commands below one by one to install the driver.

• First, list all available drivers via command:

  sudo ubuntu-drivers list

  Skip the  “udevadm hwdb is deprecated. Use systemd-hwdb instead.” output. It’s a warning that does not matter.
  

• Then, either install the desktop  or gaming use driver via command:

  sudo ubuntu-drivers install nvidia:580

  Or, install the server or computing purpose driver:

  sudo ubuntu-drivers install --gpgpu nvidia:580-server

  

Finally, restart computer and enjoy!

In addition, for Ubuntu with default GNOME Desktop, it by default fall back to Xorg session, you need to manually switch back Wayland session (if need) from login screen.

For NVIDIA Optimus laptop, it by default runs in hybrid mode. You can right-click on an application or game icon and choose “Launching using Discrete Graphics Card” to start it via NVIDIA GPU while leaving all others handled by integrated GPU.

Or, run command below in terminal to set environment variable, so all apps start from that terminal will be rendering via NVIDIA GPU:

export __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia

If you want to run Ubuntu desktop with NVIDIA only mode, then launch “NVIDIA Settings” and navigate to PRIME Profiles page to make a switch.
