TechTip: IFS Containers Part 3, Installing Open Source from the Internet

One of the core tenets of open source is freedom to obtain and use software. Now it's time to see that benefit in action.

aaron bartellWritten by Aaron Bartell

In the first article of this series, we learned about how IFS Containers could be manually created by copying things into a new directory and then running the chroot command against that directory. This was a laborious process that would cause the technology to not be used unless some amount of automation was introduced. In the second article, I introduced the IBM i Chroot (ibmichroot) project, which addresses the automation of creating IFS Containers in a matter of minutes and even more important, uniformity. In this article, we will navigate through the other core feature of the IBM i Chroot project: package installation.

TechTip: C# for RPGers - Introducing Lists

Lists are a special type of “thing” in C#; they have no parallel in RPG. This is most unfortunate, because lists are awesome!

rafael victoria preiraWritten by Rafael Victória-Pereira

The last couple of TechTips introduced Arrays and explained the foreach loop. This kind of sets the stage for the List data type. You can think of a List as an Array with all the bells and whistles and none of its limitations. For instance, when you define an Array, you have to define its size. That value is (more or less) definitive, because the memory will be statically allocated to store the variable. Lists, however, are dynamically allocated, which means that you don’t have to specify the size of the List. Actually, you can’t specify it. Instead, you’re able to specify the initial capacity, but even that is optional.

Practical RPG: Processing Stream Files, Part 2

In part 1, we processed a directory. In part 2, we process one file in that directory.

joe plutaWritten by Joe Pluta

Stream files are not database files.

 

While that statement is obvious to programmers, it's not always clear to the greater community. The end users, the folks whose jobs we are supposed to be supporting, use various forms of stream files to store their data, and they don't understand why we can't for example just "use this spreadsheet" as part of our application. And while that's an interesting philosophical discussion, as programmers we sometimes have to simply get things done, and that in turn means taking whatever data the user sent us. I've spent a lot of time over the years importing data primarily from Exceland more specifically from comma-delimited files. Two techniques exist: CPYFRMIMPF and parsing the data in RPG. CPYFRMIMPF is a completely different animal that perhaps can be covered another day. Today, I just want to talk about parsing a stream file.

RPG Academy: Write Better Code - Commenting and Documenting Strategies

Usually, programmers don’t comment their code appropriately, for a variety of reasons: “I don’t have the time,” “My code speaks for itself,” etc. Mostly, they simply hate doing it. Let me try to refute these excuses with practical strategies and tools.

rafael victoria preiraWritten by Rafael Victória-Pereira

As I’ve said throughout this series, a procedure’s name and parameter list should be enough for the programmer to understand the objective of that piece of code. However, there are times when this is not enough: complex procedures, generic names, uninspired input/output parameter names…and the list goes on and on. The next section of this TechTip will help you in the process of creating proper documentation for your newly created procedures and functions, with a few tips of what you should and shouldn’t do.

Murphy’s Security Law

Holes are everywhere. Address them before someone addresses you.

steve pitcherWritten by Steve Pitcher

A couple articles ago, I talked about the need for modernizing encryption on our IBM i partitions. Shutting one door can shut others, and shutting other doors may give you a false sense of security when you have a few windows open. You can drive yourself batty looking for these holes, but every now and then a hole finds you.
