    A pinch of hardware – Makerbuino

    I would like to tell you about a different videogame console that is a bit different from the others. Why different? Does it have an even faster processor? Even more RAM? Can you play Crysis on it? No … It has an ATmega328 as a processor (you probably have heard about that chip, it is the one that comes with Arduino), 2KB of RAM and a screen… Full HD? 4K? Umm no… A black and white LCD with a resolution of 84 x 48 pixels. Yes, exactly, like the good old Nokia 3310.

    Ah, but I haven’t told you the best … It doesn’t come assembled, and that’s exactly what made me buy it. Assemble your own console that you can then play on? Interesting, right? 🙂

    Based on Gamebuino, another similar console project (although this one does come assembled, it is not necessary to dust off the soldering iron… Booring), this console promises to have fun both when assembling it, when playing and even when coding games for it (yes, it is Arduino after all. You have all the freedom to create games, applications and everything you can think of (even some hardware hacks, since it has a couple of I2C expansion ports)).

    The project itself is not new. It dates from the beginning of 2017, and was quite successful on Kickstarter, its launch platform. They are still selling copies from their website , so you still can get one. Why not?

    Easy sortable and filterable lists in HTML/Javascript with List.js

    Let’s leave SAP aside for a while to talk about HTML and Javascript, which I also like 🙂.

    In a personal web project, I needed an easy way of making lists which data I could filter and sort, and a quick search on Lord Google gave me the answer: List.js

    List.js is a light and quick JavaScript library that let’s you easilly create data listings, allowing sort, search and much more.

    Like any JavaScript library, first we’ll need to download it and link it in our HTML document.

    <script type="text/javascript" src="/js/list.min.js"></script>

    We will define a div for out list, in which we will create our list with
    and tags. A class needs to be defined for the list. For now, we will leave it as “list”. List.js will search for this class to interact with the HTML.

    <div id="lenguajes">
    <ul class="list">
    <li>
    <p class="puesto">Puesto: 1 <img src="/img/oro.png" alt="" /></p>
    <p class="lenguaje">Lenguaje: Java</p>
    </li>
    . . .
    </ul>
    </div>

    Debugging a dialog window

    If you have been working with SAP for a while debugging programs, you’ll most probably know the “/h” command, that activates the debugger from any SAP transaction.

    Maybe then you have stumbled upon a program/transaction which does not have the command box enabled, so it would seem is not debuggable. An example of these transactions is CG3Y, which main window is a dialog, which locks the focus and does not allow the execution of commands in the command box at the top left corner.

    In case we need it, how do we debug this transaction then? One of the solutions is having in hand an SAP command file. Open a notepad, paste the following code and save it with any name:

    Icons in transport requests

    Transport requests. The way of moving changes between systems in SAP. Maybe you have seen a transport request with an icon in the description, like below:

    An icon in the description? Yes. Isn’t it nice? Apart of looking nice, it is useful for distinguishing transport requests, for example, the ones that contain changes being done, the ones being tested, the ones ready for transport… But, how do we use icons in the description?

    El Programador Ibérico, now in English

    Welcome to “El programador Ibérico” (The Iberic Programmer”), a blog attempt where I will share with you information about the software development world, like tips, tricks, code examples and even some news now and then.

    But first of all, who am I? My name is Luis Alejandro Domínguez Bueno, a young (but unfortunately less young every time) man from Malaga, in Spain, who is passionate about technology and software. I have grown up taking apart every gadget that I have put my hands on, so I have learned a couple of things about electronics too. In a particular moment in my life, I became interested in software development, and I started making my first test videogames in environments like GameMaker and RPG Maker. I took a Superior Grade Formative Course in Computer Application Development, and I currently work at Accenture, where I learned about SAP and ABAP development.

    When I started this blog 6 years ago in Spanish, I thought the majority of my posts would be about SAP, since that’s what I was working with, but most of my posts have been about Arduino or similar development boards. I do not promise regularity in the time between posts, but I promise interesting content (interesting for us geeks 😊).

    English is not my native language, and I don’t have any formal studies on it. I just learnt it consuming media in english. Because of that, my english probably is a mix of american and british, and I will probably write things in a more complicated way than a native person would, but I’ll try my best 😉.

    Not a lot more to say. I will see you in my next post!
