What Is the Bullworker?

The Bullworker is an exercise device that's used for isometric exercise. It features spring-loaded, contracting cylinders and users push inward on both ends of the device to work the arm muscles. It has strap down the side which expand the workout to include pulling out for lateral workouts. This design allows the Bullworker to be used for exercising the legs and lower body.

But if you have found this blog then you know that anyway  ;)

How to get IBM i command line during runtime using System Request 3

  • Posted on: 5 January 2014

Here's a blast from the past:

I was just testing an IBM i program that is importing data from a Windows Server, converting the data, juggling it, tweaking it and when its finished playing it finally shoves it into an IBM i Database. Fun Fun FUN! But if its running interactive and I want to quickly get the command line... I'm stuck. The green screen is input inhibited. Luckily, we can easily get command line access by tweaking the system request functions of IBM i.

HACKEAT EMPTOR - obviously only grant this command line access if your system i is properly secured. You dont want any old Tom, Dick or Harry getting to the command line to do you?

The system request functions do a bunch of neat things during any interactive session - SysRq/2 shows a DSPJOB command. Luckily its super easy to change the command associated with all the system request functions.

Right now, lets quickly tweak the sysrq/2 function.

Death of a Landrover LR3

Well, not really the death, lets call it 'moving over to the other side'. Whatever we call it, Boris won't be haunting me any more.

The final straw was breaking down on Christmas Day! Bloody useless thing!!!

So, my New Years resolution is to admit defeat and get a reliable car. This morning, I finally faced reality and dispatched the car to the Auctions. I know I could get much more money selling privately, but I honestly wouldn't be able to look another person in the eye and tell them "it's a great car please pay full price". Letting an auction deal with it, assuages my guilty heart. Amazingly the LR3 started and drove there with no problems  #miracle

I've spent a week looking at my finances and realized that this problem is just never going to go away and it's time for me to stop thinking with my heart (I love driving this car) but to think with my head (this car is so unreliable you are an idiot to consider keeping it) and my bank balance (sell it, buy a cheap clunker and wait till you have recouped your losses)

How to Reset or rebuild a Sitemap in Drupal

A sitemap is exactly that -- a map that search engines read to find what is on your website.

Sitemaps are a simple way of keeping the main search engines like Google or Bing up to date with what is going on with your website. I mean, why bother writing a website if nobody every reads it right? 

The XML sitemap module creates a sitemap that conforms to the sitemaps.org specification. This helps search engines to more intelligently crawl a website and keep their results up to date. The sitemap created by the module can be automatically submitted to Ask, Google, Bing (formerly Windows Live Search), and Yahoo! search engines. The module also comes with several submodules that can add sitemap links for content, menu items, taxonomy terms, and user profiles.

I can almost guarantee that you are reading this because you searched for something on a search engine and it bought you here. It only knows about this website because of the website map 'sitemap.xml'

The sitemap is pure XML (a kind of funky HTML) and basically lists everything that is on the website and looks something like this:

use LIBHTTP to talk SOAP to websites using RPGLE on IBM i

Thankyou -- Scott Klement!

HTTPAPI (LIBHTTP) on IBM i is the bomb. Luckily I am not boarding a plane at the moment, so I can use that kind of language without getting strip searched by some burly TSA agents.

Firstly, I have never met Mr. Klement but (like almost every IBM i Developer out there) have read many of his excellent articles about programming and tinkering with IBM i systems. Secondly, the man is a genius and I owe him a very large beer. After spending far too long investigating various techniques to get my IBM i system to talk to an external website (Authorize.net in this case) and being led down many wrong roads... I stumbled across scott's collection of open source RPGLE programs called HTTPAPI.

In Scott's words:

Download HTTP API source:

This is an RPG IV service program that uses socket calls to implement the HTTP 1.1 protocol. The HTTP protocol is the data transfer protocol that is used to transfer documents over the World Wide Web.

This service program can, optionally, also do "https" (HTTP over SSL) requests to an SSL-enhanced web server.

This is a powerful utility with many uses, so I'm opening it up to the world. Since this has only been tested for a few applications with a few servers, I'm looking for people to help out with testing, documentation and maybe even with new features.

Have Fun! 

What happened to the Forums?

Hello websurfing chaps and chappettes,

Over the years this website has been through many, many changes - from HTML to Flash to Joomla to Wordpress and finally to Drupal. A couple of years ago, I decided to import lots of my old programming and AS400 specific documentation into the website and imported everything in Drupal 'forums'. Primarily as an easy place to reference old technical articles and because I thought some of the older 'RPG Programming' questions just might help the IBM I community out there. Apart from my burbling blogs, the forums are easily the most accessed part of the website.

However, I now find myself spending (wasting) time every day deleting spam, moderating people leaving nasty comments and just basically being annoyed by the inability of some people to have sensible conversations using online forums.

So - whats the solution?

Social media is the answer. Over the last couple of years I've increasingly chosen to use Facebook and Twitter to communicate. I've also integrated DISQUS into every article on the website, as it has superb antispam tools built into it. Effectively the entire website is now acting like a forum with facebook and twitter being the new places for chatter and banter.

So, if you're looking for a Forum - STOP LOOKING. They are dead. Gone. Deceased.

Talking to Authorize.net using XML, RPG from IBM i

So, for the last few weeks I've been working on adding credit card handling to a legacy RPG application with an static HTML website over the top. The application code itself was written in the eighties and has evolved through a number of different versions of RPG (a mix of RPG2, RPG3, RPG400 and even a liberal splash of RPGLE) so I've had an enjoyable task of taking a bunch of old code, re-factoring to RPGLE/free and then adding some funky web services.

Now I've added the Authorize.net CIM functions and windows to my website pages, I can manually test the payment process. Now, the authorize.net documentation is not for noobs and makes an awful lots of assumptions, so implementing this technique on IBM i (AS400) using RPG, without a modern PHP Server on the front, is not as clear as it seems. After reading everything I could on the various SOAP, XML, JAVA, RUBY techniques - I've opted for the XML route.

The next step is setting up the XML conversation to this lovely IBM i System talk to Authorize.net. After two days of googling, reading, studying, prototyping, re-prototyping, going down dead ends, trying sample code that doesn't work and repeating moaning and smacking my forehead with a wooden paddle.

So I want to

Shall we Disqus why Drupal Comments are Dead?

Spammers... I bloody hate them.

Over the last few weeks, I've had a rash of spam attacks. The modules I was using to modulate spam (Mollom, Antispam, Botcha) worked very well in blocking the huge portion of it. The downside was a big upsurge in CPU utilization on my webserver and finally getting a 'cease and desist' warning from the website abuse folks over at ICDSOFT. *sigh*

So, rather than continue to fight the evil Spam OverLords I decide to travel a different route and let someone fight the battle for me. Why handle the website comments myself when I can let an third party handle them for me.... after a little investigation I was left thinking "Facebook comments or something else to handle it?"

Facebook integration is cumbersome and my memories of doing it last time were not something I want to play with again. There is not enough hours in the day.

DISQUS is very cool.

Enough Said.

Integration of DISQUS in a Druapl7 install is simple. Grab the module from here and plop it into Drupal, then create an APP over on disqus.com for your website and add the APP Keys into your Drupal and VOILA fully managed commenting service. 

Instruction from Disqus are easy to walk through:
