Chrome OS on Vmware Fusion If you've read about Chrome OS, you know that it's basically Linux in a kiosk mode. The only apparent application available to you is the browser. However, that's not really true: a "Ctrl-Alt-T" will open up a terminal window. One there, you'll find that you are really logged in as "chronos" and that you can use "sudo" for anything you need to do as root. (password for "chronos" is "chrome")

Tightvnc, Chicken of the VNC	2003 10
- Reviews of TightVNC and Chicken of the VNC. VNC is "Virtual Network Computing" and is a crossplatform method of allowing remote access to desktops (Windows or Unix/Linux, Mac and others)). It is conceptually like using Terminal Services or PcAnywhere etc for Windows but is license free and of course capable of serving Linux/Unix machines also. -
Numeric Unix Error Messages	2001 12	2010/04/06 TonyLawrence

Dealing with Duplicate IP addresses	2009 04	2011/11/13 TonyLawrence
- Duplicate IP's on a network is an interesting problem that has no completely satisfactory solution, especially when malicious intent is involved. Let's leave those intentional conditions for another day; here we'll look at what happens when an IP gets duped accidentally. -
Compiling on Mac OS X	2006 03
- make, configure, cc need xcode macosx - which Apple provides for free, but does not install by default. -
Mac OS X launchd	2005 12
- Daemons have become pretty confusing on Mac OS X. Originally these were handled by inetd, then xinetd, and now launchd has taken over. Unfortunately, there's a mess of left over stuff hanging around: you'll still find services in /etc/xinet.d and other places -
Who locked that file?	2007 11
- Determine what process has a file locked - I can't even imagine how many times I've heard someone complain about a locked file. -

Take Control of the Mac Command Line with Terminal	2009 05
- Old-timers like me couldn't avoid being exposed to command line interfaces - that's all we had when we started Younger people and people who simply started using computers a bit later weren't necessarily exposed to any command line. Any computer they ever used had a graphical user interface and while it still may have had a command line available, there was seldom any incentive to use it. That apparent lack of any compelling reason remains true, but in fact understanding the command line can give you much more control over your computer and allow you to accomplish some tasks much more quickly and easily. -

Burning Windows Readable CD's from your Mac	2005 12	2012/10/09 TonyLawrence
- Mac OS X Tiger has a neat new feature for burning CD's: from the Finder's file menu, you choose New Burn Folder, and then drag whatever you want to burn into that new folder. Open the folder, and you'll notice a Burn button just above the files. Pop a blank CD in and click that to burn the files to cd. -

Cell Phone Internet Connections	2003 06
- How to use your cell phone as Internet access point. You can get text messaging with almost any cell phone nowadays, and it's no great trick to forward email to that. The problem is that it's too hard to read that way: long messages get broken up, the cellphone doesn't have a great keyboard, and it just isn't worth the trouble. -
Printing to a remote printer with a dynamic address	2003 06

New Battery for MacBook Pro	2009 02	2011/06/18 raj
- I bought this Macbook Pro three years ago this February. When I first got it, the battery life was decent, but not up to the advertised specs. At best I could only get two hours out of it. Because of that, I bought a spare a few months later - I figured that was a good thing to have anyway. -

New To Unix	2005 01
- Understanding how and why Unix and Linux are not like Windows. Unix and Linux are different. If your first exposure to computers was DOS or Windows, some of what you learned there is going to trip you up in the Unix world. This article attempts to both explain how Unix is different, and also why it is different, because if you understand why, you'll find it easier to remember. -

- Fugo is a Mac OS X SFTP, SCP and SSH Frontend with some very strange quirks. -
Disabling Spotlight	2005 12	2010/03/31 TonyLawrence
- I feel sorry for the Apple developers who worked on Spotlight. I'm sure they put a lot of effort into it, and likely think it's a great feature. I suppose it must be disappointing that so many of us don't use it and don't want it even running. -
Leopard Directory Services - dscl and related commands	2007 11
- I was no great fan of netinfo, so these new dsmemberutil,dscl,dseditgroup,dsenableroot commands are a welcome change. -

- Using multiple ip addresses on one machine can avoid confusion and lost links. -
Mac OS X dd backup	1997-2004
- Personally, this makes me a bit nervous. Unflushed disk buffers could mess this up, though apparently he's been ok with it. The system is running while this is dd'ing in either direction. Maybe you aren't doing anything, but background tasks are running, and I would think it would be easy to get the disk into an inconsistent state. Apparently that hasn't happened, but I would think that sooner or later dd'ing mounted drives is going to bite him. Were I going to use this, it would be in single-user mode only. -

- Sandbox-exec can protect yoy from unknown binaries -
Awk vs. Perl	2009 11	2012/08/15 TonyLawrence
- Sure, I used to use awk. When I used it, you weren't likely to find Perl onmost Unix systems, so for a lot of text mangling, awk was at least easier than writing in C or anything else. It did the job, and you'd get used to its quirks. -
OS X Console Log Monitoring	2009 06
- Unixy people tend to look at logs more often and that habit should have come with me to OS X -
Tomorrows's date	2006 03
- Tomorrow's date is what?: With a very little effort, almost anyone should be able to figure that out themselves: "man date" is a good start. It might take a little more effort to get to the "date +%s" solution": you might need "man strftime" also. But it is all there. -
iPad app file extensions	2010 05	2011/08/05 TonyLawrence
- Finding iPad uti file extensions can be confusing. There is an app that lets you look up the apps that belong to particular extensions, but you don't need to buy anything to find the extensions that an app you own recognizes. -

Fixing Large Kerio Mailboxes	2008 05	2011/11/29 TonyLawrence

Progress Bars	2005 12
- Your Mac OS X shell scripts can have progress bars. We all know that software progress bars have to be taken with a large helping of salt. It's not at all unusual for the bar to have no discernible relationship to reality, and this is particularly apt to be true for operating system installations and software installs. -
CleanCode Email	2003 11
- Using Cleancode email client - a neat little command line utility for scripting outgoing mail without Sendmail. -

Prevent deletion or moving of files	2009 10
