modem dtr -->Re OSR5 <sys/termio.h>
The native OSR5 devsys is installed from the main OSR5 operating system CD (the label even says so, in medium-small print). The UDK comes on its own separate CD with big huge letters, to make sure you install the wrong devsys, which you've apparently done.

| Building contact lists from IMAP searches | 2012 04 | ||||
| - Did you ever think of data mining your emails? Your business emails are a rich source of information that can be used for compliance checking, building contact databases, spotting trends and so on. Use this simple code as inspiration for your own ideas! - | |||||
| Implementing a second level Spam folder with Kerio Connect | 2012 03 | ||||
| - Spam is spam, but some spam is spammier than others. We can use a Perl script to sort out second level spam. - | |||||
| Perl Profiling with Devel::NYTProf | 2011 07 | ||||
| - I don't think I have ever used a profiler on my own code. The reasons are simple: I don't write much that is very complicated, so any bottlenecks are usually rather easy to spot. Most of what I do is ad hoc and limited use anyway, so speed is seldom a consideration. - | |||||
| Using fail2ban with Kerio Connect mailserver | 2011 06 | 2011/07/14 Pat | |||
| - Fail2ban is fussy about dates in log files; Kerio's security log does not meet its standards - | |||||
| Perl Date::Manip for date validation | 2011 05 | ||||

| Snarling Panda site cleanup | 2011 03 | ||||
| - The problem is "low value content". That's tough to define absolutely, but some pages here definitely fall into that category - | |||||
| SpamCheetah as it stands today | 2011 03 | ||||
| - SpamCheetah is a greylisting spam control technique and it is more of a spam blocker rather than a spam filter since it really does not filter anything. - | |||||

| Writing and Compiling C programs on Linux | 2004 12 | 2012/02/10 TonyLawrence | |||
| - Writing and compiling c programs on Linux, common errors for beginners. Most Linux and Unix programs are written in C. When you download source for a project, it will often be C or C++ source code. You don't necessarily need to know a darn thing about C or anything else to compile the source if you aren't changing it. It may be helpful for you to understand a bit if you are having problems with the compile, but even that isn't really necessary. - | |||||
| Perl Getopt and GetOptions | 2003 09 | 2013/02/26 TonyLawrence | |||
| - Two Perl modules (Getopt and Getoptions::Long) work to extract program flags and arguments much like Getopt and Getopts do for shell programming. The Perl modules, especially GetOptions::Long, are much more powerful and flexible. - | |||||
| Perl Net::FTP | 2003 09 | 2013/03/13 armin | |||
| - Before the wide spread availability of Perl, I would script ftp transfers with .netrc, ksh scripts and other clumsy ways. None of those methods are fun, flexible or easy. On the other hand, Perl's Net::FTP module is all of that. - | |||||
| Perl Input | 2003 10 | 2011/04/08 TonyLawrence | |||
| - Perl has wonderful I/O capabilities. I'm only going to cover input here: reading from files or standard input. There are two ways to do that (actually a lot more than two, but this is supposed to be introductory material): you can open a specific file, or you can pass files on the command line and either open them individually or just ignore the whole thing and pretend everything is coming from STDIN. - | |||||
| Python vs. Perl | 2003 12 | 2010/06/02 anonymous | |||

| RedHat RPM Source Packages | 2001 06 | ||||
| - Ever wanted to rebuild a RedHat RPM from source? I had an issue where I wanted to include one of the new features offered by SAMBA that enables logging to utmp in RedHat 7.1 and RedHat 6.2. Since RedHats supplied binary RPMs did not include this support, I had two choices: one was to download the SAMBA source, and compile the feature in from there, and my other choice was to possibly use the RPM source that RedHat supplies with their RPMs. - | |||||

| Understanding Floating Point Formats | 2003 09 | 2011/10/28 TonyLawrence | |||
| - Understanding basic floating point. Under ordinary circumstances, you don't have to know or care how numbers are represented within your programs. However, when you are transferring data files that contain numbers, you will have to convert if the storage formats are not identical. If the numbers are just integers, that's fairly easy because the only differences will be the length and the byte order: how many bytes the number takes up, and whether it is stored lsb or msb (least significant byte or most significant byte first). Once you know that, conversion is trivial. - | |||||

| Why does Firefox use Sqlite? | 2008 05 | 2012/11/27 anonymous | |||
| - Why does Firefox use Sqlite database instead of text files? Am I nuts? Am I the only person who can't imagine why Joe Firefox User could possibly have enough bookmarks or browsing history that you need a database to manage the data? - | |||||
| Custom Tab Completion | 2004 12 | 2009/12/12 zolo | |||
| - I'm sure you already know about tab completion: type part of a command name and hit TAB and you get its matches. Leave a space and then hit TAB, and you get filenames. Wonderful stuff. - | |||||
| Use and Abuse of /usr/local/bin | 2000 01 | ||||
| - It starts when some poor soul has written a script to do some thing or another, and happens to mention that it was called "/usr/bin/whatever". Of course the hapless poster usually had no real reason to mention its path, that was just an accident, or it appeared in some other script that was being posted for examination. No matter, the damage is done, for immediately some defender of the faith is going to chide the poster and sanctimoniously inform them that the proper place for home grown scripts is /usr/local/bin. In some cases, that's all the poor person gets: whatever the question originally was is forgotten and only the placement issue is discussed. - | |||||

| Text vs. Binary Data formats | 2003 10 | ||||
