Managing Text Clipping Snippets On Mac OS X Just in case you somehow missed this, Mac OS X will create a "Clipping" file if you just drag a chunk of selected text to your desktop. You can later drag that back anytime you want to paste the same chunk somewhere else. That's nice - it augments the Clipboard Utility that I use. But there were several things I did not like about Clippings so I seldom used them.

The Seven Layer inedible OSI cake   2013 08

Trapping errors in Bash   2013 08 
- While I think you need to avoid getting too clever in shell scripts, trapping errors can be useful. -
'ps' and 'grep'   2013 08

tput and stty   2013 08

Is rm final? Can I get my files back?   2013 08  2013/08/07 BigDumbDinosaur
- Is rm final? Are the files gone forever? It depends on what you mean by really gone and also depends upon your file system, your OS, and rm itself. -

Length of a domain name   2013 08

Sparse Files   2013 08

What does 'everything is a file' really mean?   2013 07 
- Everything is a file? How ridiculous: is a horse a file? How about a pitcher of beer dumped over the nearest Unix geek's head - is THAT a file? -
Why won't IT staff recommend Macs or Linux?   2013 07  2010/01/20 anonymous
- Microsoft pays close attention to what people want. They may do a horrible, botched job of providing it initially, and at the next revision, and so on, but eventually they do provide decent products. -
Why does so much of Unix and Linux have to be hard?   2013 07 
- Obviously you have REASONS for sharing whatever it is you shared. Sometimes those reasons are completely altruistic, sometimes not. -
Shebang - What's the point of #!/bin/bash?   2013 07

Determine Unix/Linux version and cpu's   2013 07

Deleting a lost file name - delete unremoveable files   2013 07

Using Windows 8 in Parallels Desktop Mobile   2012 10

No clobber scp - scp without overwriting   2012 10  2012/10/07 TonyLawrence

Kerio Connect and Apple Open Directory Part 3   2012 09  2013/07/05 TonyLawrence
- As I started to investigate the slapd.conf on the Mountain Lion Open Directory, it seemed to me that it could not be working - but it was! -
Kerio Connect and Apple Open Directory Part 2   2012 09  2012/10/11 TonyLawrence

Mountain Lion Server in Parallels Desktop   2012 09  2012/09/21 TonyLawrence

Avast Free Antivirus for Mac   2012 05  2012/05/30 NickBarron
- Will someone please make decent malware/antivirus protection for Macs? I'd hope that Apple would be smart enough to do that itself, but so far they seem uninterested and that leaves me feeling worried. -
Kerio Troubleshooting   2012 05  2014/07/03 TonyLawrence
- There are only a very few things that will completely prevent Kerio Mailserver from starting. Usually this would come from a confused or mangled configuration file, but there are other conditions that can cause Kerio to refuse to start. -
Where is the boing? (Mac scheduled startup)   2012 03  2014/04/06 TonyLawrence
- I first noticed the missing Mac startup chime a few weeks ago. It seemed very odd that if I rebooted, the chime did work - it was only the first boot of the day when it did not "boing". Starting up took too long also - something was wrong, but what? -
iPad recovery mode problem caused by bad backup   2012 03  2012/03/12 TonyLawrence
- When my iPad started crashing Thursday night, it looked like bad hardware. I was even more sure of that when I tried to recover from a backup and it crashed doing that. I took it to the Genius Bar and they agreed, but we all were wrong. -
Simple outgoing email for SCO Unix (and Linux)   2012 02  2013/05/22 rblake
- Configuring MMDF or Sendmail on SCO Unix was never fun and it only gets worse as fewer people care about any of it. Here is a simple fix for scripted outgoing email -
OS X 10.8 Mountain Lion   2012 02  2012/02/21 BrettLegree
- When will they quit these dumb cat names? Anyway, Apple, you did good in dropping the price of Lion, but you screwed up on the performance side -
Exploring Apple Document versions   2011 11 
- When I made the switch, I of course had files under the old account. Some were things I knew I'd need immediately, so I copied them to the new account and changed permissions. Others were things I might need, but then again I might not. What to do about those? -
Kerio Connect Mailserver version 7.3   2011 11 
- Kerio Connect Mailserver version 7.3 is scheduled for release in early November 2011 and adds important features, including a few that I suggested and lobbied for earlier. -
Chrome Mouse Gestures in OS X Lion and the Ghost Arrow   2011 11 
- One of the things that you can do is swipe left or right (one finger swipe) to move between pages you have visited in Safari. Even if you'd never read about gestures, you'd be likely to figure that one out because Safari animates the acyion and begins to slide the other page in as you start the swipe. As it's easy enough to accidentally start a small swipe, you'll notice this. -
Is Microsoft about to shoot itself in the foot (or even its head) with Windows 8?   2011 09  2011/09/30 RonCam
- That's a serious question. I don't claim to have an answer, of course, but I do think the answer very well could be 'Yes'. -

New 21.5 inch iMac review   2011 09  2011/09/12 NickBarron
- I could replace the MacBook Pro (or buy the MacBook Air), but my iPad answers 99% of my portability needs - I felt that either a Mac Mini or an iMac would be better. After hemming and hawing this way and that, I decided to go with the 21.5 inch iMac. It has more memory expansion, and more raw cpu. -
Death of the command line revisited   2011 09  2011/09/10 TonyLawrence
- Five years ago I wrote a little blurb called Death of the command line. As it happened, that article was misunderstood by many who read it - I don't know if it was my fault or theirs, but somehow many readers ended up thinking I was either predicting the demise of CLI's (Command Line Interfaces) or hoping for that demise or both. Nothing could have been farther from the truth. I remain a big fan of CLI's and use them daily. And yet, just five years later and still at risk of angering yet another batch of folk who won't read carefully, I'm going to suggest that predicting the death of the CLI may not be such a bad bet after all. -
10 things - no, 11 things - you say that drive your computer tech person crazy   2011 08  2011/09/20 anonymous
- Yes, of course people sometimes say or do silly things, even outright stupid things. We all do. Look me straight in the eye and tell me you have never done anything like that with a computer and I'll look you straight in the eye and tell you the same thing and then we'll both try not to laugh. -
Switching to Mac OS X - quick tips for new users   2011 08 
- First thing, understand that I'm not going to try to convince to to switch. I f you are stuck in the world of Microsoft, I feel sorry for you, but making you understand that you should switch is not my purpose today. This article is just quick tips for those who have decided to switch. -
Basic Home Networking, Part 3, File and Printer Sharing   2011 08 
- The point of a computer network is sharing. You might not be sharing much, perhaps even only the Internet connection. If that's the end of it, you don't need much more than part one of this series, which deals with the setup of a basic small network. -
A few minor iPad set up problems baffle my neighbor   2011 08  2011/08/28 anonymous
- A neighbor took advantage of MA's recent tax free weekend and bought an iPad. He'd seen mine and his daughter had shown off hers the last time she had visited, so he had a pretty good idea of why he wanted it. Unfortunately, his initial experience was frustrating. -
Basic Home Networking - Part 2, wireless setup   2011 08 
- Often all that needs to be done is to tell your computer that you want to connect to a wireless network. It's not always that easy, but it certainly can be. However, even if it is that easy for you, you might still want to read the rest of this in case you have problems later. You also might want to read it because being "too easy" to get connected could mean that you are running some security risk and need to address that issue. -
Basic Home Networking - routers and switches   2011 08  2011/08/16 BigDumbDinosaur
- Setting up a small office or home network used to be a fairly complicated task. Aside from the technical knowledge needed, there was expensive equipment to buy and specialized tools for wiring. That's all changed - the necessary equipment is cheap and readily available and it's all very easy to configu re. -
A non-technical guide to understanding and fixing TCP/IP problems on a network   2011 08  2011/08/14 BigDumbDinosaur
- The title is a bit incorrect in the .non-technical. claim, because we are dealing with a geekish subject here and I can't avoid being a little "techie". -
