Running Internet Explorer on Linux through Wine is theoretically possible but practically untenable. If you need to test in IE, understand upfront: Wine support for IE is broken, unmaintained, and will waste your time. Why IE on Wine Doesn’t Work Internet Explorer depends on a stack of Windows-specific components that Wine’s compatibility layer can’t reliably…
The built-in etags command doesn’t recursively traverse directories by default, but generating TAGS files across your entire project is straightforward with the right tools and setup. Using ctags (Recommended) The simplest approach is ctags with the -e flag, which generates Emacs-compatible TAGS files: ctags -e -R . The -R flag enables recursive traversal. This works…
Amazon S3 has a maximum object size of 5TB per object. This limit applies uniformly across all storage classes and regions — there are no exceptions or workarounds. Understanding the 5TB Ceiling The 5TB limit is a hard constraint at the API level. You cannot upload, copy, or restore an object larger than this. While…
SSH is fast enough for most tasks, but when you’re transferring large files, running multiple commands, or managing hundreds of servers, every millisecond counts. Here’s how to squeeze real performance gains from SSH and SCP on Linux. Choose the Right Cipher Cipher selection has the biggest impact on throughput. Modern CPUs have AES-NI hardware acceleration,…
When you need to reach a server through one or more intermediate hosts, you can establish a direct connection without manually chaining SSH sessions. This is essential for accessing internal servers that aren’t directly reachable from your workstation. The scenario laptop —-> proxy —-> server You want to connect to server.example.com through proxy.example.com as if…
Converting LaTeX to HTML while preserving figures is essential when publishing technical documentation online. The right tool depends on your document complexity and output requirements. tex4ht (htlatex) tex4ht is the most reliable option for LaTeX documents with figures, math, and complex formatting. It’s part of the TeX Live distribution and available on all major platforms….
Memory leak detection is critical for C program reliability. Several tools work at different stages of development—compile time, runtime, and production scenarios. Your choice depends on performance tolerance, integration needs, and how much detail you require. AddressSanitizer (ASan) AddressSanitizer is the first tool to reach for in 2026. It’s compiler-integrated, fast, and catches a broader…
When you need to identify which package installed a command on your Fedora system, you have several reliable methods depending on whether the package is already installed. Quick lookup for installed commands The fastest approach combines which to locate the command with rpm to query the owning package: $ rpm -qf $(which ping) iputils-8.40-4.fc40.x86_64 The…
When network interfaces fail or behave unexpectedly, you need to inspect driver details, hardware state, and kernel messages. Here’s the practical toolkit for diagnosing network hardware and driver issues. Kernel Messages and Logs Start by checking kernel logs where driver initialization and errors are recorded: dmesg | grep -i network dmesg | grep -i driver…
The most reliable one-liner to count files in the current directory is: find . -maxdepth 1 -type f | wc -l This counts only regular files (not directories or symlinks) and handles edge cases that trip up simpler approaches. Why Not Use ls | wc -l? The common ls | wc -l command has several…
Fedora upgrades are straightforward with dnf system-upgrade, the standard tool for network-based distribution upgrades. This replaces the older fedup tool and handles everything from downloading packages to managing the upgrade environment. Pre-Upgrade Checklist Before starting any upgrade: Update your current system: sudo dnf upgrade Back up critical data — especially /etc, home directories, and application…
Emacs startup time matters when you’re opening files frequently from the command line or in scripts. A few targeted optimizations can reduce perceived startup overhead from seconds to near-instant. Run Emacs as a daemon with emacsclient The most effective optimization is the server/client architecture. Start Emacs once as a daemon, then reuse that instance for…
The cut command is designed for simple field splitting, but it has a hard limitation: the delimiter must be a single character. cut –delimiter=”delim” -f 1,3 # Error: cut: the delimiter must be a single character This is a deliberate design choice. cut prioritizes speed and simplicity for common use cases like splitting on tabs,…
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 need to combine multiple video files (like video1.mp4, video2.mp4, and video3.mp4) into a single output file, FFmpeg is the standard tool on Linux. It’s faster, more reliable, and better maintained than older tools like mencoder. Using FFmpeg with the Concat Demuxer The most robust approach uses FFmpeg’s concat demuxer, which properly handles file…
Several tools can convert .doc and .docx files to PDF from the command line. Here’s what works in practice. LibreOffice (most common approach) The standard command is: libreoffice –headless –convert-to pdf –outdir /path/to/output/ /path/to/file.docx This works well on systems with X11 available. However, on truly headless servers, –headless doesn’t fully suppress X11 requirements—LibreOffice will still…
Linux systems can have multiple timer sources available, and the kernel selects one as the active clocksource. Understanding what’s available and how to view or change the current source is essential for performance tuning and troubleshooting timing-related issues. View the Current Timer Source Check which clocksource is currently in use: cat /sys/devices/system/clocksource/clocksource0/current_clocksource This will output…
If you have emails stuck in Evolution’s local directory structure that you want to move to an IMAP account via Thunderbird, you’ll need to convert them to a format Thunderbird can import, then push them to your mail server. Step 1: Prepare Your Evolution Mail Directory Evolution typically stores mail in a Maildir format with…
Broken links damage SEO, hurt user experience, and undermine site credibility. Checking for them should be part of your regular maintenance routine. Here’s what’s available in 2026. Online Tools W3C Link Checker (http://validator.w3.org/checklink) remains a solid option for checking individual pages. Point it at a URL and it crawls the page’s links, reporting broken ones…
Redis is an in-memory data structure store designed for speed and simplicity. Understanding its architecture and consistency guarantees is essential for deploying it correctly in production systems. Core Architecture Redis operates as a single-threaded, event-driven server that uses an in-memory data store with optional persistence. The single-threaded nature simplifies reasoning about concurrent access — all…
