The dropped posts, and 2017 closing

I’m not constant in my writing. Some ideas come, some ideas go, some get written, some get lost.

For the end of 2017 I deleted a backlog of drafts that were half written. Some of them were actually quite nice but unfinished. The problem being that I may have lost the content that was discussed in those posts, or just forgot what I was writing about. It’s not a new year’s thing, but let’s start clean here πŸ˜€

When I was ready to press the button I felt sad for those posts, so here’s a list of the posts lost in battle.

  • Arduino Clock Time Reading. (The arduino clock posts)
  • Arduino Clock Display usage. (more arduino clock posts)
  • littlebits.cc (I never got around to even touch those, but looked awesome)
  • A serial terminal with python and custom commands. (Used as a complement on embedded projects at IDNEO)
  • DynamoDB Django Python middleware. (What a combo! but actually I’m using this daily :-p even if I barely remember what I did there)
  • Static websites with Hugo. (Liked the idea, stayed in wordpress so far. With my combo of wordpress + it’s all text + gvim.. sadly It’s all text does not work anymore)
  • Python and Pyinstaller. (It was mostly finished, but it seemed too shallow)
  • Some book reviews (Never was too fond of them anyway)
  • A small map I made after a short hike.
  • A small classification of Barcelona neighbourhoods according to rent price and buildings age (Yes, I did that when hunting for a new apartment)
  • A small labyrinth game in Game Boy assembler.

Nevertheless, 2017 has been a good year for me personally. Changed from an Embedded job too far away from home (1.5h commute by train) to an Embedded Linux job too close (5min walk), been very involved in a personal project and enjoyed my free time playing drums and kayaking πŸ˜€ .

Blogwise it is the first year that I ALMOST accomplished the one post per month mark! (sorry, summer is summer)… I am not a journalist and this blog is not my priority so it is surprising that I’ve found the time to keep it updated and half interesting. This year we had:

And the “previously” page got updated with a bunch of games and books that I liked this year. I played more than what I’ve read….. this is something to think about.

I never talk about the site stats. It is a small place after all. Nevertheless, this blog has maintained something like 1000 visits per month. That feels like a lot to me, so thanks to everyone who read my stuff and got something useful from it πŸ˜€

It has been a long way since I started in 2012, from a 25 year old guy that was bored during a master degree and wanted to improve his English writing skills, to a slightly older guy (you do the math) that is doing something completely different but enjoying it.

That’s it, no more retrospectives, 2017 has ended and we are still alive, let’s go to 2018.

PD: I have nothing written yet for 2018, I’m going to lose my monthly post combo πŸ˜›

Git config

Lots of us use git in a daily basis, myself included. We can say a lot of git, but I would not say that it is intuitive, or that it has nice shortcuts. Similar to what happens with VIM, over the course of some years and some jobs I collected a small list of git configurations that I find very comfortable to work with.

Damn! I failed again, no posts on summer πŸ˜€

Europe DbPedia 2017

europeflagdbpedia
I was kind of bored while doing some work, and just past week we were discussing with a colleague about my vague-places project.

This project was forgotten in time, but today I’ve blown the dust away, recovered it, and updated the Europe DbPedia map.

Image overview

Most of you won’t be interested in the full story. So here, see a set of results. If something picks your interest (like, why Portugal has almost no points) just keep reading πŸ˜€

A 3×3 font for Led Matrices

fontIcon

For the clock project I require text to appear in a small container, that is 4×4.

Since in this 4×4 I have to add vertical and horizontal spacing this ends with a 3×3 font.

Never in my life I designed a font, and if you check my hand writing… it is horrible. Luckily 3×3 only leads up to 2^9 options, 512 different characters, and I believed I could handle this.

After writing the font in a squared notebook, I checked that other fronts already exist, and, unsurprisingly they were very similar to mine.

Show me your font

ST HAL I2C address (SHIFTED!)

stlogo

Quick note, for those who might be banging their head, like I did.

ST HAL library 7 bit I2C address has to be shifted before passed to their functions.

EDIT: Let me google that for you situation. I’ve been working with the official ST documentation, when I just had to google to find this beautiful blog post from 2 years ago.

Explanation
