The benefits of getting to grips with Vim are immense in terms of editing speed and maintaining your “flow” when you’re on a roll, whether writing code, poetry, or prose, but because the learning curve is so steep for a text editor, it’s very easy to retain habits from your time learning the editor that stick with you well into mastery. Because Vim makes you so fast and fluent, it’s especially hard to root these out because you might not even notice them, but it’s worth it. Here I’ll list some of the more common ones.Moving one line at a timeIf ...

Takeaway: If you prefer to use vi or vim for command-line editing, you can configure shells to use vi key bindings instead of emacs-style key bindings. Here’s how. By default, most shells use emacs-style key bindings for command-line editing and modification. For users of vi or vim, however, you can instead configure shells to use vi key bindings instead. This is done by editing ~/.bashrc in the case of bash, or ~/.zshrc in zsh and adding:set -o viin bash, and the following for zsh:bindkey -vOnce you have saved either ~/.bashrc or ~/.zs...

Backstory While at RIT around 2004 or 2005, I discovered that a few important machines at the datacenter allowed all students, faculty, and staff to authenticate against them via ssh. Everyone's shells appear to be set to /bin/false (or some derivative) on said machines, so the only thing you'll see after you authenticate is the login banner and your connection will close. I thought to myself, "Fine, no shell for me. I wonder if port forwarding works?" Seems reasonable, right? Whatever sysadmin was tasked with securing these machines forgot some...

Yes, even if you can't believe it, there are a lot fans of the 30-years-old vi editor (or its more recent, just-15-years-old, best clone & great improvement, vim). No, they are not dinosaurs who don't want to catch up with the times - the community of vi users just keeps growing: myself, I only got started 2 years ago (after over 10 years of being a professional programmer). Friends of mine are converting today. Heck, most vi users were not even born when vi was written! Yes, there are definite reasons why the vi/vim editing model is just superi...

Amitwas curious whyit takes longer for Task Manager to appear when you start itfrom the Ctrl+Alt+Del dialogcompared to launching it from the taskbar.Well, you can see the reason right there on the screen:You're launching it the long way around.If you launch Task Manager from the taskbar,Explorer just launches taskmgr.exevia the usual Create­Process mechanism,and Task Manager launches under the same credentialson the same desktop.On the other hand, when you use the secure attention sequence,the winlogon program receives the notification,switches to the secure desktop,and displays the Ctrl+Al...

Many people hack together shell scripts quickly to do simple tasks, but these soon take on a life of their own. Unfortunately shell scripts are full of subtle effects which result in scripts failing in unusual ways. It's possible to write scripts which minimise these problems. In this article, I explain several techniques for writing robust bash scripts. Use set -u How often have you written a script that broke because a variable wasn't set? I know I have, many ti...

I've been using MacVIM as my editor of choice for a couple of years now, yetin many ways I still feel like a beginner. Every day I am learningmore and more about my editor, but it takes a conscious effort to become proficient withan editor like Vim. Here's why I make that effort.Editors are something that are very personal; they have to fit with your ownwork flow approach to programming. If you have ever stopped to think about it,the way each person goes about editing text is quite different. I frequentlypair program with colleagues and I find it amazing, and sometimes frustrating,to see how o...

The rave reviews for the latest iteration of Microsoft’s Windows Phone aren’t the only reason Microsoft will do better in the smart phone industry than it did in the MP3 player market.Whereas the Zune never really offered anything substantially different from the iPod and never pushed any real boundaries, Microsoft’s latest push into the mobile operating system business is much more bold. Microsoft isn’t rushing it this time – and it shows.So far, tech pundits of all stripes are pretty impressed with the Windows Phone OS and its evolution. We can’t be ...
