General hints I think might help others that I have come across over the years.
In my latest bit of training, I learned about sed and awk. sed is a line editor (stream editor) (scripting with ed). awk is a pattern-directed scanning and processing language and divides each line to fields by separating words by spaces or other specified field separators. Some tidbits about using sed to quickly edit files: […]
No, the site was not hacked, I chose to write about regular expressions. I am in my last section of my UNIX/Linux Systems Administrator training and I am equally excited about regular expressions as I was about learning subnets. I know regular expressions are very powerful, and I remember enjoying subnets after I finally figured […]
Well, my friend Ben accidentally passed a link on to me that I wanted to pass on to others. If you use Firefox and you want to speed up your web surfing when you use your broadband connection, check out this cool guide.
While I am taking my UNIX/LINUX Systems Administration training, I pick up cool UNIX tidbits and it is time to share some more of my latest tidbits. (First installment) Random commands and information I have jotted down: When compiling something from source code, I used to always use: ./configure then make then make install, but […]
Well. Today I relived my college days as a student taking Math 110 (Business Calculus). I felt like I understood…so much that I thought I got a 90% or above on the exam…then reality would set in and I would get a 47%. Welcome to 2004, Networking/DNS now replaces Math 110…and I am stuck on […]
Sometimes the GUI is awesome. Sometimes you just need more control over your conf files that the GUI offers. I wanted to have more specific firewall rules for my computers and servers running Mac OS X Client, more than the default OS X 10.3 built-in firewall configuration that is provided. First, let’s look at all […]
Well, I am halfway through my UNIX filesystem training and I wanted to share some useful commands I have learned along the way: grep -i = grep ignoring cases grep -v name = grep ignoring all lines with “name” in it grep word * = grep in the current directory for all lines with “word” […]
Spam. We are all sick of it. Contact information…if you have a web site it is most likely you will need to post your contact information (email address) somewhere. To stop robots from spidering your email address, I would suggest encoding it. Yeah, if you notice my email address is not always encoded on my […]
If there is one application Apple has released in the last few years that I should be using more, it is iCal. There are lots of little tricks and cool stuff you can do with iCal…like my favorite: In a terminal window type: cat /usr/share/calendar/calendar.history | grep McDonald and look at the goodies. Yes, I […]
If you ever need to serve a web site for, let’s say a presentation, on a local address and need to connect to another computer…perhaps your database/ Web Objects server locally as well, and you are running Mac OS X…then I have some information for you. If you want to serve the web site on […]
Ever since I started monitoring what search engine robots indexed on my web sites, I have also been using Google Alert. Google sends me reports (html email or plain text, your choice) of any web site that has been indexed with keywords that you specify. Not only can you make sure Google is following the […]
Well, I have been fishing for the last few days, which I enjoy…but I do not enjoy the fishy smelling hands that I have after I get home. After 2 days of no solution…my not so in-law brother in law told me he finally figured out how to kill the smell: sun tan lotion. I […]
