Unix and Linux Help, Resources and information for Unix/Linux, Mac OS X and other general computing related topics. Thousands of articles, reviews, consultants listings, skills tests, opinion, how-to's, suggestions and more. This is the Blog section, which always has the newest additions. There is new content daily, most of it exclusive to this site, and all of it is indexed and cross-referenced to help you find what you need. This is not yet another mirror of the Linux LDP or someone else's Unix FAQs. If you've never been here before, there's a lot to explore.

Google Adsense and recession

2008/10/10

It's a simple question: will a recession hurt the world of on-line advertising?

A Tale of Backup

2008/10/09

I've had my share of customers who won't make backups. I've had customers who have left the same media in the backup device for years on end.. sometimes those even end up with happy endings that the customer definitely did not deserve.

Questions on ssh

tporter

I am new to SCO as of 6 months ago, but am picking up fast. I consider myself somewhat fluent to SCO but am having troubles on one particular issue. I help support a number of sites with SCO 5.0.5/6/7 I was not aware at the time that 5.0.7 included SSH during install and thus I automatically installed the package I had ftp'd to the machine. I have never been able to get SSH to connect between this SCO 5.0.7 machine and a RH4 machine. I know that the 5.0.7 included SSH version is called from sd and seems to use a different # generator other than the prngd I installed with my version. The SSH I installed on top of the current one would be called from /usr/local/sbin/sshd rather than the /usr/bin/sd sshd....

Some questions about Self Employment

2008/10/07

Quite a few years back I wrote a piece on Successful Consulting. It's a longish thing, and if you are considering entering the world of self employment, I recommend reading it. However, it didn't cover everything, and particularly it skipped over a few questions that were added as comments recently:

* Who do you get your healthcare from, and approximately what percentage of your operating costs is it?

Google Precipitate

Google Precipitate simply gets Spotlight to index your Google Docs and Google Bookmarks. It does so in the obvious way: bringing down info to a file and setting its "Open With" attribute to "Precipitate", which will launch a web browser in turn.

Dial-up and Broadband

I've talked before about my reluctance to get involved with home users. There are several factors at play here - for one, home users are most apt to have detestable Windows as their operating system. That's enough to turn me off right there.

CPU sucking processes

A few weeks back one of my larger Unix customers called about some small issue. We dealt with that, and he then off-handedly asked "More memory should speed things up, right?"

Gloom and Doom

Well, here we all are, waiting to see what happens next. Are we heading for a big crash? Recession? Inflation? Stagflation?

New Phone

I need a new cell phone. My current phone is almost four years old now and like all of its predecessors it has been dropped, smashed, soaked and abused beyond reason. Its once shiny features are pitted and scratched, but against all expectation, it still works.

Mac OS X Security Guides

These PDF OS X security guides came out a few months back at http://www.apple.com/support/security/guides/. Although primarily concerned with corporate environments, even a home user can benefit from reading these. I downloaded the Mac OS X Security Configuration Guide (there's another version for Server).

Zoom in

I thought every Mac user knew about this, but I have found quite a few that did not, so I'm mentioning it here "just in case". It's "zooming" and I believe it is enabled by default - if not, you'll find it is System Preferences, Keyboard and Mouse, Trackpad (assuming you have a trackpad). It also works with a scroll wheel mouse and if for some reason you have neither, it's available as hot-keys in Universal Access, Seeing, Zoom (that's NOT on by default).

What went wrong

It's Friday, September 19th, 2008. I just listened to our mumbling and "mispronounciating" President announce further government involvement in the mortgage mess.

Printers Down

I had a call from an old SCO Unix customer this week. There aren't many of those old systems left now - more than you'd probably think, more than there should be, but far less than there were just a few years back. I think you still have a good chance of finding a few SCO boxes in any city, but it's getting harder..

Lazy umount

I was actually looking for something else when I noticed that Linux umount has a "-l" option:

Nobody uses Macs

I just got back from a technical training session. Nothing odd about that, of course; I go to these kinds of things all the time. This was a small session with a total of approximately a dozen people counting the two presenters. Nothing odd about that, either: many of these sessions are small.

Chrome

I am so ticked off about Google Chrome that I almost wasn't going to even mention it here. Why am I ticked? Well, it's bad enough that there is currently only a Windows version, but that snub becomes even more insulting when you realize that Chrome was built with Apple's Webkit!
