Top 10 Computer Tricks Every Geek Should Know

We’ve talked before about the things every computer user should know how to do, but we geeks are special: we want to go above and beyond, to explore every nook and cranny of our system and make everything easier. Here are 10 ways to do just that.

10. Find New Uses For The Programs You Already Have

Chances are, you’ve probably already found a few awesome tools and added them to your productivity arsenal, but most programs can be used for more than just their intended purpose. The file-syncing Dropbox, for example, is also great for monitoring your home computer, printing files from afar and even downloading stuff with BitTorrent. Savvy folks can use Gmail to store files in the cloud or find out if someone’s stolen your laptop. Any tool can become multipurpose if you know its ins and outs.

9. Use The Command Line Like a Ninja

Using the command line isn’t as exciting as it looks in the movies, but it can be a very useful tool (in fact, some tools are just better in the command line). It’s pretty easy to learn, too — check out our command line primer for beginners to learn some basic commands. Once you’ve got that down, read up on the best shortcuts that help you navigate the command line like a ninja. Those guides apply to UNIX-based systems like Linux and OS X, but if you’re a Windows user you can grab something like Cygwin to get a similar experience (or, if you want a more Windows-centric tool, try Powershell).

8. Read And Understand Your Resource Usage

When your computer starts acting a little slow, a lot of people jump to their resource monitor to see what’s causing problems. However, just looking at a bunch of charts and graphs isn’t going to tell you what’s wrong unless you really know what you’re looking for. High CPU is a common problem with one app slowing your system down, and as soon as you close it, the issue should go away. High network activity could be the cause of slow internet or slow file transfers over the network. RAM usage, however, is where a lot of people get thrown off: high RAM usage isn’t inherently a bad thing. Know the difference between good and bad RAM usage before you start blaming processes. If you want to keep an eye on your resources, check out our favorite system monitors for Windows, Mac, and Linux, too.

7. Run Everything On A Schedule

Stop performing all that system maintenance yourself and set it all up to run on a schedule. With Windows’ built-in Task Scheduler, you can run just about any kind of task — whether it’s maintenance, picture uploads, or even a simple alarm (in fact, it’s one of the best Windows 7 features you’ve probably forgotten about). Mac users looking for something similar should check out Tasks Till Dawn.

6. Know Your OS’s Hidden Features

Every operating system has hidden things lying under the hood, you just have to know where to look. Windows users should check out the hidden features of Windows 7 and Windows 8, while Mac users should peruse the hidden features of OS X Lion and Mountain Lion. If you want to find even more, you can often find them in Windows’ Registry or in OS X’s terminal. System tweakers like Ultimate Windows Tweaker, OnyX for Mac, and Ubuntu Tweak are also great places to find secret features.

5. Learn To Crack Passwords (And Protect Yourself)

Everyone should know how to create a secure password, but responsible geeks can take it a step further by learning how to break into a comptuer. This skill — whether used on a Windows machine or a Mac — can really help you understand how computer thieves and hackers will try to get at your data. Learning the process means you know how to protect yourself against the process — not just with strong passwords but with encryption and other settings tweaks that keep thieves out. Similarly, you may also want to learn how to crack a Wi-Fi network’s WEP and WPA password.

4. Navigate Everything With Your Keyboard

There are certain basic keyboard shortcuts everyone should know, but if you really want to use your computer more efficiently, you can take it so much further. Learn the most common shortcuts for your favourite programs, like Gmail, Microsoft Word, basic text boxes and even Facebook. After a little while, you’ll be able to blow through menus and text boxes with unbelievable speed. Check out our guide to becoming a keyboard ninja, complete with a bunch of cheat sheets to help get you off the ground.

3. Run A Basic Linux Distribution

Even if you don’t want to switch operating systems, knowing a few Linux basics can be really handy. With a live CD on hand you can troubleshoot your machine, revive an old, slow PC, and make your way through Linux-based DIY projects. Check out our five-part guide to getting started with Linux, and be careful — it can be quite the rabbit hole once you get into it!

2. Squeeze More Power Out Of Your Hardware

With a bit of tweaking, you can push your hardware past its original limits and get some pretty serious bang for your buck. When it comes to your PC, you can overclock your processor and video card and even install OS X on non-Macs by building a Hackintosh. And, while you’re at it — even though it isn’t a computer trick specifically — you should try turning your $US60 router into a $US600 router with DD-WRT.

1. Program Your Own Dead Simple Scripts

You don’t need to learn an entire programming language to write advanced scripts. Windows users can do a ton of awesome stuff with AutoHotkey, from creating simple keyboard shortcuts to controlling their PC remotely. To get started, just check our beginner’s guide to AutoHotkey and our list of the best AutoHotkey tricks. Mac users don’t have anything quite like AutoHotkey, but you can do quite a bit with the built-in, insanely easy-to-learn AppleScript. If you aren’t the coding type, check out Automator on the Mac and its clone, Actions on Windows.

When all is said and done, this is probably way more than 10 tricks, but if you don’t know any of the above, they should keep you busy for a while. If you have an idea we didn’t list, be sure to mention it in the comments below.
