Writing a Custom Backup Solution

If you are a user of any form of computer and care one bit about your sanity, then you probably have a backup strategy. Otherwise, if all hell breaks loose and your whole computer burns to ash or the hard drive melts to a heap of metal, turning it into an ugly door stop, you’ll likely be kinda angry, maybe slightly pissed, your pulse most definitely at 180, that you’ve lost all your data. I’d certainly be, especially about all my pictures of all the festivals and places I’ve been to. 

(And maybe some family 😅)

But, to be honest, I’ve been a bit lazy about backups for some time now. I do have copies of all my important files, but that’s not a backup. It’s a copy. A backup lets you go back in time and get an older version of a file or folder, not just the most recent one that has been synced.

So why is it, that I’m not as diligent as I should be? There are a few factors in that equation. It’s laziness for one, knowledge that I do have at least one copy, the fact that I haven’t had any data loss so far and stinginess. Why the latter? Up until now, being a Windows user (not any more though, on my main machine), I was relying on Acronis True Image, a commercial backup software. However, the version that I own – 2014, I think – stopped being reliable in one of the past Windows 10 versions. I simply don’t want to spend the money any more.

I’m not here to tell you that I have changed my mind on that. No. I’m, of course, coding my own solution. Why wouldn’t I? Everything is done multiple times in the Open Source community.

Jules White Programming Cloud Services YouTube Video Series

In my search for information about what a web.xml exactly is and does, I ran across a video series on YouTube of Dr. Jules White who created over 70 videos explaining the basics and advanced topics of creating web services for mobile applications. The videos are roughly between 5 and 15 minutes long, so they are ideal for in-between watching, without sacrificing in content. You can binge them too, of course.

What I found most pleasing is that his presentation style is very informative and professional. There are no awkward pauses or anything else that would make me cringe. It’s very pleasant to watch and there’s a lot of good information in it, even for someone that already has a background in building web applications.

I created this list of links to all the individual videos because wanted to have more structure and information than a YouTube Playlist can provide in case I want to go back and watch something particular. Additionally, there’s a little sorting and numbering bug in the YouTube Playlist 😉

So, here you (or I) go.

Using Groovy Spock in a Maven Java Project

Groovy Spock is a testing framework that can be used as an alternative to the venerable JUnit. In Java projects it’s probably very common (I don’t have any data, just an assumption based on how I think) to also use a Java based testing framework. The most widely known is JUnit, although not the only one of its kind (e.g. see this article on DZone). However, Java’s syntax can sometimes be rather cumbersome and verbose, and this is where a dynamic language like Groovy can help. It is often used to create nice and interesting DSLs, e.g. as the basis of the Gradle project or, as in the case of Spock, for testing.

Here’s how to integrate the Groovy Spock testing framework in a Maven based Java project.

One thing up front: I’m no fan of Groovy. I’ve worked with Grails projects for several years and using Groovy has more than once proven to be a problem. Especially in very large applications. However, I do see the benefits it can provide in certain situations and I have come to like the more expressive, although sometimes odd to read, Spock DSL in tests.

Bad Coding Habit: Append Needless Words to Classes

This is a short opinion piece about a very good talk I’ve been watching recently. It was presented by Kevlin Henney and is about seven ineffective coding habits of many programmers. Not only is his style very engaging and entertaining, it also contains seven informational things a coder might want to think about. While I generally agree with all of it, there’s one instance where I can see why it is done – if that’s the actual reason is a question for another day. I’m talking about appending the word Exception to classes that are exceptions.Read More »

WorkTracker 1.4.0 Released

Yes, you read that right. I have released a feature update for my WorkTracker tool. There was one little annoyance that I worked around by using copy and paste and since it was just a few key strokes, I didn’t bother. But in my renewed motivation to do some coding, I thought that it’s about time this issue goes to hell. And now it’s being grilled by Lucifer.Read More »

Apple WWDC 2018 Announcements – A few thoughts

As I do every year, I watched the Apple WWDC 2018 keynote, for personal entertainment purposes as well as a genuine interest in what Apple is doing. The same is also true for both Google’s and Microsoft’s developer conferences. This is not a comprehensive summary as done by other Apple news sites and blogs, but rather  a few thoughts on what I’ve seen and how it may or may not affect me.

iOS Update Strategy

Every year, and with good reason, Apple mocks Google’s Android platform for lagging behind in the software update department. This year was no different, as was to be expected, but in addition to that they emphasized the support of devices dating back to 2013. Five-year-old iPhones and iPads! Take that Android.Read More »
