2026-07-16T16:20:10.183+05:30

Not sure why your Linux system is sluggish and not performing to its full potential? Is the CPU overloaded, is the memory almost full, or is your system’s disk having some problems? You are not alone in facing this problem. Fortunately, Linux collects enough data to analyze the root cause of slow system performance. You need to know where to look for this data. In this tutorial, we’ll take a look at some of the best tools and utilities you can use to monitor Linux system performance. Whether you are running a home computer or a production server, these tools do the job flawlessly. Let's get started!

How to Remove Hidden Metadata From Microsoft Office Files

2026-07-13T16:00:00.000+05:30

You hit ‘Send’ on that Word doc attachment. Tidy formatting, zero typos, looks great. Now you’re done. But are you? Deep within that file is an invisible information dossier about you: your real name, company username, the version of the software you used, how many revisions the doc underwent, and even entire sections of text you thought you had removed from previous drafts. Load the same doc into another application, and anyone can extract the data in 10 seconds. It’s called metadata, and nobody ever remembers that information exists until it causes them embarrassment. A law firm mistakenly exposes a client’s strategy via change tracking in a shared Word doc. A freelance worker sends out a ‘final’ contract to a prospect, with an internal critique intended solely for her own team embedded within it.

2026-07-02T16:33:33.875+05:30

Let’s say you grabbed your friend’s old laptop and plugged in a USB stick. And within a minute, you get access to a text editor, web browser, file manager, and various diagnostic tools.

Whether you are a developer or an IT technician, a Windows toolkit on a USB drive is a must for troubleshooting PC problems. You don’t need to be a computer wizard to create such toolkits. In this tutorial, we’ll learn to create a portable Windows toolkit that can be booted from a USB stick.

How to Encrypt Sensitive Files Before Uploading to the Cloud

2026-06-29T14:04:31.153+05:30

The vast majority of users think their files are safe once they’re uploaded into Google Drive, Dropbox, or OneDrive. While, to some degree, they are, as these services leverage HTTPS for encryption in transit and AES-256 in transit. There’s a big secret these services do not put on their flashy advertising posters: they hold the encryption keys. That’s right! They can access and read every single file you upload, whether it’s due to a data breach, government subpoena, careless employee, or simply their own system bug. It all resides there to be read by an outside force that’s not you. Sounds scary?

How to Identify Unknown Devices in Windows Device Manager

2026-06-25T12:25:54.936+05:30

You try to fix a driver problem in Device Manager and are greeted by a yellow exclamation next to "PCI Simple Communications Controller". It gives you no manufacturer information and describes nothing. Another piece of hardware with a name only a programmer could love. Does this sound like you? Every Windows user has to deal with this sooner or later. An OS reinstall, a driver pack for the motherboard that forgets to include a chipset driver, or a touchpad that decides to identify itself no longer or operate, and we are left with few entries listed as "Unknown Device" under "Other Devices".

How to Mount and Repair Corrupted USB Drives in Linux

2026-06-22T15:31:55.538+05:30

Your USB drive doesn’t show up when you plug it in. Worse, maybe Linux mounts it, but you can’t open a file; instead, you see the dreaded, incomprehensible I/O error message. We all know the sickening sensation when you think, “My USB drive is corrupted,” don’t we? I do. Good thing there’s hope! A corrupted USB drive isn’t a dead drive, and in my experience, Linux is one of the world’s greatest operating systems for fixing or restoring corrupt data from storage devices. This tutorial guides you step by step, from manually mounting the device to recovering lost data, using Linux commands to repair an error-ridden file system, clone an unreliable disk image, and recover lost files or even partitions.

How to Clone a Website the Right Way

2026-06-18T16:50:33.663+05:30

Imagine this: You’ve just applied a major theme update, or updated the checkout page, or just completed a server migration, and everything looks ok on your monitor. You push everything to the production environment, and ten minutes later, you start receiving emails from users who are annoyed or frustrated by a broken page. Your superior is asking what went wrong. This happens every day, and most of it is avoidable. It doesn’t require more coffee or a firmer mouse click. Just test changes on a copy of your website before you hit live with it. Cloning a website sounds like something only ‘real’ DevOps Engineers will be doing with tricky server configurations. Actually, it is something anyone from a freelancer or a single site-owner to a developer working at an enterprise can do by the end of the afternoon.

Obsidian vs Logseq: Which Knowledge Management Tool Wins

2026-06-15T15:44:42.153+05:30

You've likely heard this saying before: "Your second brain should work just like your first one". That's exactly what PKM (personal knowledge management) tools promise, and the current undisputed giants in that domain are Obsidian and Logseq. Each tool offers the capability to capture thoughts, make connections between notes, construct your personal knowledge base, and cultivate clearer thinking. Both are Markdown-based. Both are local-based. And both have devoted-or cultish, as it were- communities surrounding them. So which one should you choose? That depends completely on how you think, what you're building, and what you intend for your notes to become.

Speed Up Windows 11 With These Powerful Registry Hacks

2026-06-11T16:08:22.392+05:30

Is your Windows 11 machine getting slow and unresponsive? Maybe the Start menu is taking a while to pop open, your right-click menus are taking a bit longer than usual, or your PC may take too long to shut down. Surprisingly, some of these speed issues are not due to weaker hardware. More often than not, they are due to inherent animations, delay processes, and behaviors that Windows implements for a better graphical interface and compatibility. That is where Registry tweaks come in handy. The Windows Registry is the master database storing operating system information.

How to Write and Manage systemd Unit Files for Custom Scripts on Linux

2026-06-08T19:00:54.606+05:30

Did you write a Python script to watch how much disk space is left on your server? Or a bash script to push files to a remote server every few minutes? It runs great on the command line; you reboot your server, and it disappears. Then you have to SSH into it again, navigate to that directory, and execute the command to get it to run again. Sound familiar? This is exactly what systemd was designed for, and once you learn how to work with it, you will wonder how you ever survived without it, relying on cron job hacks. systemd is an init system and service manager present in all Linux distributions.

20 Blogging Mistakes That Are Hurting Your Traffic

2026-06-04T16:00:00.000+05:30

Publishing blog posts is easy. Getting consistent traffic from them is not. Many bloggers write regularly, install SEO plugins, share posts on social media, and still wonder why their traffic graph stays flat. The problem is usually not one big mistake. It is often a collection of small blogging mistakes that slowly kill visibility, rankings, clicks, and reader trust. According to Ahrefs, 96.55% of pages receive no organic traffic from Google, underscoring how competitive blogging has become. Most posts fail not because blogging is dead, but because they are poorly planned, poorly optimized, or not useful for readers.

25 Git Tricks That Make Developers More Productive

2026-06-01T16:00:00.000+05:30

If you work with Git daily, you already know one key aspect of working with Git: even tiny tweaks can spare you hours of trouble. The average programmer knows about only about a hundredth of what's possible in Git. Their workflow usually looks like: clone, branch, commit, push. And it is functional until a repository scales up, your team-wide collaboration becomes chaotic, or a faulty merge makes you want to throw your computer out of the window. The truth is that advanced programmers use dozens of Git secrets to significantly improve their efficiency and reliability. And, not everyone knows about it.

The Ultimate OpenAI (ChatGPT) Image Prompting Guide

2026-05-18T09:28:33.150+05:30

AI image generation has officially broken through. Once primarily a novelty party trick-you tell it something vague, and it gives you something weird-it has become a fully-fledged creative pipeline, relied on by marketers, indie developers, educators, filmmakers, and sole founders. But, despite how powerful the models have gotten, most individuals are completely squandering vast amounts of quality on the table. Regardless of whether you're creating generations with GPT Image (gpt-image-1, gpt-image-2) on the API or within ChatGPT's 4o Image Generation, or using other text-to-image systems, the distinction between a usable or exceptional asset is nearly always dictated by prompt structure, intent, and detail.

What Is Zero Trust Security? A Simple Guide for Normal Users

2026-05-09T10:18:00.003+05:30

Cybersecurity terms can sound intimidating. "Zero Trust Security" sounds even more confusing, almost like something from a spy movie or a government agency. But the idea behind Zero Trust is actually very simple. Imagine you lock the front door of your house. Traditionally, once someone got inside, you trusted them completely. They could walk into every room, open every drawer, and access everything. With Zero Trust, every room has its own lock. Every person must prove their identity again before entering another room. Even if someone is already inside the house, they are not trusted.
