Happy New Year everyone, with a little delay. I was busy in the first two weeks of this year preparing and delivering the “Leveraging Git” webinar. It turned out to be quite a success, but it also prevented me from doing my live session last Friday. But this short break doesn’t mean I am not going to get busy with my blog and live blog again. This is what’s coming up. Today, at 14:00 CET, I’ll go live again at https://vjeko.live/ and this time the topic is HttpClient patterns. I am going to demo how to get from a very naive HTTP execution based on direct invocations of HttpClient…

Oh how much fun we had today on my live stream, it’s just amazing. First, all the viewers had fun of waiting for me to go live for nearly an hour, and then at some point I managed to unplug my reflector. Perks of live streaming First of all, I would like to – once again – apologize to everyone who waited for me to go live. I’ll explain in the end of this blog what really happened. For now, let’s go on-topic. If you didn’t have a chance to follow my stream, you can check the recording from here: Today’s session is important because it illustrates why you would actually want…

It’s been a few days that I announced the “Leveraging Git” webinar on my Twitter and LinkedIn and I hope nobody will mind if I announce it on my blog. So, here we go. Every year I deliver between five to ten trainings. This year, I delivered a grand total of zero, due to the coronavirus outbreak. Times are changing, and I need to adapt. So, following the example set by my two friends, Waldo and AJ , who have already delivered webinars, I have decided to try the same. The webinar focuses on Git as an essential development tool, rather than just a way to replace those ugly //BugFix…

One thing we learned from lessons learned is that we don’t learn from lessons learned. Somebody, alegedly I don’t know where this quote comes from, a one-minute googling didn’t reveal it to me (but it isn’t mine, I’ve read it somewhere for sure). Anyway, a month ago I started live streaming . This year with grand total of zero live conference sessions delivered must have been a contributing factor. I believe I miss speaking. So I decided to give it a try. Now, almost exactly a month later, with five total streams delivered, four of which with actual relevant content (the first was…

Today I had my fifth live stream. The topic was interfaces , and this time I took a different angle at it: patterns. When I polled about live stream topics you’d like to hear about, most of you said “patterns”. So today’s stream covers several patterns and puts them in perspective of interfaces, or the opposite way around, however you like it. The stream is available on my new http://vjeko.live/ page, and here it is if you hate clicking: Inversion of Control The first pattern I talked about was inversion of control . It’s not really a pattern, it’s a design principle. If…

After a lot of fun with interfaces on Friday, I’ve received a lot of very encouraging feedback. It seems that the decision to start live video blogging was right, and I am sticking with it. I’ve realized that on Friday I didn’t announce any schedule for the period ahead, so here’s what we are going to do in coming Fridays. December 6: From JavaScript to AL and back For the record, this is the topic that actually kicked off the entire idea of video blogging. A while ago, there was a very short thread on Twitter which again, for umpteenth time, told me that the way how the control…

Today I’ve streamed the Fun with Interfaces video blog at https://www.youtube.com/watch?v=QSMHL32c5mg and the recording is now published online. This was the first session I ever delivered about interfaces, and I actually planned delivering this a lot earlier (I made a suggestion to run this at Directions ASIA before corona crisis hit), but never had a chance. I now polished the demos a bit and delivered it as-is (no slides, really, so – no theory, just practice). I will have more to say on interfaces, definitely. Stuff like dependency injection, inversion of control, testability…

Source code files are living things. We add new ones and change their content on daily basis. Occasionally we delete them, too. Git is amazingly efficient when it comes to tracking these kinds of changes. However, sometimes we need to change the file name, or file path, or both. And if you are an AL developer who has ever transformed a C/AL project into AL, you have probably done this at least once, for all .al files in the project. And this is where git may surprise you. After you rename a file, sometimes you’ll notice that git detects it as a rename. But on other occasions it will…

A lot of us still have a ton of C/AL code sitting around in existing databases that sooner or later will have to be moved into AL. A lot of us also have a ton of AL code using DotNet that we want to be able to run in Microsoft’s cloud (that is: not on-prem). And I guess most of us don’t want to maintain a DotNet-less and DotNet-ful versions of our code. Sooner or later, you’ll want all of DotNet out of your AL. Even if you are a seasoned .NET developer, you’ll want all DotNet out of AL. Anyway, when you need to replace DotNet, what options do you have? Let’s take a look at all possible…

Thanks to everyone who watched my live stream today! The audience wasn’t big, but it’s a very narrow topic, not of broad interest. Still, I am glad I got a few interesting questions that actually introduced my future topics quite nicely. You can find the recording here: As promised, I have published the GetImageResource.js file on my GitHub. You can find it here: https://github.com/vjekob/RandomBits/tree/main/src/js (There you can also find some usage notes and explanation why you may want to use that file in your control add-ins) Once again – thanks, and see you next…
