The TP-Link TL-WN725N v2 uses the Realtek RTL8188EU chipset. While kernel support has improved significantly, you may still need to compile drivers manually on recent Fedora releases. Check current driver status First, verify whether your adapter is recognized: lsusb | grep -i realtek If nothing appears, the driver isn’t loaded. Check if the kernel module…
Sharing a router with roommates means dealing with bandwidth conflicts. When someone’s running torrent clients, streaming, or other bandwidth-intensive applications without limits, everyone else suffers. Here’s how to handle it systematically. Start with conversation Before implementing technical controls, talk to your roommates. Most P2P and download applications have built-in rate limiting. Asking someone to cap…
When you have shared Makefiles included across multiple projects in different directory structures, relative includes break. If common.mk tries to include release.mk and both files are in a subdirectory like external/, the include fails because Make uses the current working directory, not the location of the including file. For example, this structure works fine: Makefile…
AddThis provides social sharing buttons for websites. If you’re using the AddThis Tweet button and want to add a via parameter (to attribute tweets to a specific Twitter account), here’s how to configure it. AddThis Tweet Button with via Parameter Modify the AddThis button configuration to include the tw:via attribute: <!– AddThis Tweet button with…
Finding large files is something you end up doing a lot — disk fills up, you need to track down what’s eating space, or you’re auditing a directory before archiving. The find command handles this cleanly. Basic usage Find all files larger than 500MB under the current directory: find . -type f -size +500M The…
The default GNOME Settings application doesn’t expose font configuration options. You’ll need additional tools to customize system fonts, but you have several approaches depending on your GNOME version and preferences. Using GNOME Tweaks GNOME Tweaks (formerly gnome-tweak-tool) is the recommended graphical approach for font customization. Installation On Fedora/RHEL: sudo dnf install gnome-tweaks On Ubuntu/Debian: sudo…
GNOME Shell in GNOME 3 uses a specific font for the top bar, activities overview, and system notifications. You can customize these fonts using GNOME Tweaks or dconf to match your preferences. Using GNOME Tweaks (Recommended) # Install GNOME Tweaks sudo dnf install gnome-tweaks # Fedora sudo apt install gnome-tweaks # Ubuntu Open GNOME Tweaks…
Broken symbolic links accumulate over time and can cause confusion or errors when scripts rely on their targets. Identifying and cleaning them up is a regular maintenance task. Basic approach Use find with the -xtype l test to locate broken symlinks: find /path/to/directory -xtype l The -xtype l flag specifically matches symbolic links that point…
When managing user accounts on a cluster or application, you’ll often need to generate temporary passwords programmatically. Here’s a practical approach using Scala’s built-in utilities. Basic implementation with scala.util.Random For non-security-critical use cases, here’s a straightforward generator: def randomString(len: Int): String = { val rand = new scala.util.Random() val chars = “0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz” (0 until len).map(_…
Domain registration pricing has commoditized significantly over the past few years. Most registrars cluster around similar price points, and permanent discounts are increasingly rare. Rather than chasing one-off coupons that expire or have restrictive terms, understanding how registrars price domains and what you actually need will serve you better. Current Market Rates As of 2026,…
These four languages share functional programming roots but diverge significantly in syntax and design philosophy. Here’s a practical reference for anyone transitioning between them or evaluating which to use. Basic Function Definition OCaml: let add x y = x + y let rec factorial n = if n <= 1 then 1 else n *…
Writing effective paper reviews is essential work in academic fields like information retrieval, machine learning, systems research, and most technical disciplines. Whether you’re reviewing for a conference, journal, or internal research group, the goal is the same: provide constructive, specific feedback that helps authors improve their work and helps decision-makers assess contribution. What Makes a…
WhatsApp dominates global messaging, but several strong alternatives exist depending on your use case, privacy requirements, and regional adoption. Here’s what’s actually worth considering in 2026. Messaging Apps Built for Mobile Signal The gold standard for privacy-conscious users. Signal uses end-to-end encryption by default for all messages, calls, and group chats. Open source, no ads,…
By default, WordPress contributors can submit and edit their own posts, but they can’t upload media files. If you want contributors to attach images or documents to their submissions, you’ll need to grant them the upload capability. Method 1: Using User Role Editor Plugin The User Role Editor plugin is the most straightforward approach for…
A4-sized PDFs—particularly technical papers and academic documents—render poorly on Kindle devices. The small fonts become nearly unreadable, and Amazon’s “Send to Kindle” feature often destroys formatting in the process. You need a tool designed specifically for this workflow. Why Standard Conversion Fails Amazon’s email-to-Kindle conversion assumes reflowable text content. Technical papers with multi-column layouts, equations,…
This is fundamentally a decision about display technology and your reading habits. Here’s what you need to know. Display Technology The standard Kindle uses e-ink technology with a backlit display that requires external light sources — sunlight, a lamp, or overhead lighting. It’s readable but not ideal for low-light conditions. The Paperwhite adds a front-lit…
Gnuplot can output directly to EPS (Encapsulated PostScript) format, which is useful for including plots in LaTeX documents and other publishing workflows. Direct EPS Output The simplest approach is to set the terminal to postscript with the eps option before plotting: set terminal postscript eps enhanced mono “Helvetica” 14 set output “my-plot.eps” plot sin(x) This…
When you need to rsync against hosts behind NAT gateways or port-forwarded SSH services, the standard port 22 won’t work. The solution is the -e flag, which lets you specify a custom SSH command with your desired port. Basic usage Use -e to pass custom SSH arguments: rsync -avxP –delete -e “ssh -p 13022” username@example.com:/remote/path/…
GNOME 3 removed the GUI option for customizing window title fonts that existed in earlier versions. The setting is still configurable, but you’ll need to access it through command-line tools or configuration editors. Using gsettings (Command Line) The simplest approach is gsettings, which directly modifies the configuration: gsettings set org.gnome.desktop.wm.preferences titlebar-font ‘Sans Bold 10’ To…
Running your own Python installation on Dreamhost (or similar shared hosting) gives you control over the version, packages, and dependencies without relying on system-wide Python. This is especially useful when you need specific Python versions or packages the hosting provider doesn’t support. Why Use a Custom Python Installation Shared hosting environments typically ship with outdated…
