Bucking the System: Higher Ed, Hold the College

June 12, 2019 Alex Woodie

Jim Buck spent 15 years teaching IBM i and RPG at Gateway Technical College in Kenosha, Wisconsin. Buck achieved great things there, finding hundreds of students good jobs around the country. But ultimately the college experience grew old for Buck, so he ventured out on his own. That’s when he founded his own online IBM i educational company, imPower Technologies.

That was two years ago, in the spring of 2017. After spending almost a year getting imPower Technologies up and running, Buck is teaching students IBM i and RPG once again. Currently he offers two courses: an introduction to IBM …

Guru: Right-Size Your PHP

December 3, 2018 Alan Seiden

In my experience doing performance audits, I often point out that while PHP for IBM i comes perfectly configured for small applications, it must often be tuned to handle large workloads. When applications must accommodate hundreds or thousands of users, or use AJAX technology, two easy changes should be considered for PHP and Apache configurations.

1. PHP_FCGI_CHILDREN Setting In fastcgi.conf

On IBM i, Zend Server installs a configuration file called fastcgi.conf. Among other settings, it includes PHP_FCGI_CHILDREN, which determines how many PHP jobs run when its Apache server is started. The file — /www/zendphp7/conf/fastcgi.conf (Zend Server 9 or higher) or …

VACAVA’s Low-Code Approach To Modernization

IBM i shops have lots of options when it comes to application modernization. At one end of the spectrum are screen-scraper tools, which can provide a quick fix for shops tired with the 5250 interface. IBM i shops with more time, money, and inspiration may choose to completely rewrite their application on a new platform. Somewhere in between lies RapidBIZ, a low-code modernization affair from VACAVA.

The folks at VACAVA knows a thing or two about the IBM i platform. For starters, the company is based in Rochester, Minnesota, home of the world-famous IBM lab where the AS/400 was created …

Guru: Speed Up Web Pages Using Apache’s mod_deflate

July 9, 2018 Alan Seiden

If your web applications run on HTTP Server (Powered by Apache) for i, you can enable a powerful Apache extension, mod_deflate, to speed up your site. Just as zipping up files on your PC saves space and accelerates file transfers, mod_deflate “allows output from your server to be compressed before being sent to the client over the network.” (See https://httpd.apache.org/docs/2.4/mod/mod_deflate.html for more information.) My tests show a speed improvement of 10 to 50 percent.

You can compress any text-based output, including HTML (whether plain .html files, output from RPG CGI programs, PHP, or other languages), Cascading Style Sheets (CSS), …
