On Moving

Published August 3, 2018 / by mario / 7 Comments on On Moving

Winds of Change. One of my favourite songs ever and one that comes to my mind now that me and my family are going through quite some important changes, once again. But let’s start from the beginning…

A few years ago, back in January 2013, my family and me moved to the UK as the result of my decision to leave Igalia after almost 7 years in the company to embark ourselves in the “adventure” or living abroad. This was an idea we had been thinking about for a while already at that time, and our current situation back then suggested that it could be the right moment to try it out… so we did.

It was kind of a long process though: I first arrived alone in January to make sure I would have time to figure things out and find a permanent place for us to live in, and then my family joined me later in May, once everything was ready. Not great, if you ask me, to be living separated from your loved ones for 4 full months, not to mention the juggling my wife had to do during that time to combine her job with looking after the kids mostly on her own… but we managed to see each other every 2-3 weekends thanks to the London – Coruña direct flights in the meantime, so at least it was bearable from that point of view.

But despite of those not so great (yet expected) beginnings, I have to say that this past 5+ years have been an incredible experience overall, and we don’t have a single regret about making the decision to move, maybe just a few minor and punctual things only if I’m completely honest, but that’s about it. For instance, it’s been just beyond incredible and satisfying to see my kids develop their English skills “from zero to hero”, settle at their school, make new friends and, in one word, evolve during these past years. And that alone would have been a good reason to justify the move already, but it turns out we also have plenty of other reasons as we all have evolved and enjoyed the ride quite a lot as well, made many new friends, knew many new places, worked on different things… a truly enriching experience indeed!

In a way, I confess that this could easily be one of those things we’d probably have never done if we knew in advance of all the things we’d have to do and go through along the way, so I’m very grateful for that naive ignorance, since that’s probably how we found the courage, energy and time to do it. And looking backwards, it seems clear to me that it was the right time to do it.

But now it’s 2018 and, even though we had such a great time here both from personal and work-related perspectives, we have decided that it’s time for us to come back to Galicia (Spain), and try to continue our vital journey right from there, in our homeland.

And before you ask… no, this is not because of Brexit. I recognize that the result of the referendum has been a “contributing factor” (we surely didn’t think as much about returning to Spain before that 23 of June, that’s true), but there were more factors contributing to that decision, which somehow have aligned all together to tell us, very clearly, that Now It’s The Time…

For instance, we always knew that we would eventually move back for my wife to take over the family business, and also that we’d rather make the move in a way that it would be not too bad for our kids when it happened. And having a 6yo and a 9yo already it feels to us like now it’s the perfect time, since they’re already native English speakers (achievement unlocked!) and we believe that staying any longer would only make it harder for them, especially for my 9yo, because it’s never easy to leave your school, friends and place you call home behind when you’re a kid (and I know that very well, as I went through that painful experience precisely when I was 9).

Besides that, I’ve also recently decided to leave Endless after 4 years in the company and so it looks like, once again, moving back home would fit nicely with that work-related change, for several reasons. Now, I don’t want to enter into much detail on why exactly I decided to leave Endless, so I think I’ll summarize it as me needing a change and a rest after these past years working on Endless OS, which has been an equally awesome and intense experience as you can imagine. If anything, I’d just want to be clear on that contributing to such a meaningful project surrounded by such a team of great human beings, was an experience I couldn’t be happier and prouder about, so you can be certain it was not an easy decision to make.

Actually, quite the opposite: a pretty hard one I’d say… but a nice “side effect” of that decision, though, is that leaving at this precise moment would allow me to focus on the relocation in a more organized way as well as to spend some quality time with my family before leaving the UK. Besides, it will hopefully be also useful for us to have enough time, once in Spain, to re-organize our lives there, settle properly and even have some extra weeks of true holidays before the kids start school and we start working again in September.

Now, taking a few weeks off and moving back home is very nice and all that, but we still need to have jobs, and this is where our relocation gets extra interesting as it seems that we’re moving home in multiple ways at once…

For once, my wife will start taking over the family business with the help of her dad in her home town of Lalín (Pontevedra), where we plan to be living for the foreseeable future. This is the place where she grew up and where her family and many friends live in, but also a place she hasn’t lived in for the last 15 years, so the fact that we’ll be relocating there is already quite a thing in the “moving back home” department for her…

Second, for my kids this will mean going back to having their relatives nearby once again as well as friends they only could see and play with during holidays until now, which I think it’s a very good thing for them. Of course, this doesn’t feel as much moving home for them as it does for us, since they obviously consider the UK their home for now, but our hope is that it will be ok in the medium-long term, even though it will likely be a bit challenging for them at the beginning.

Last, I’ll be moving back to work at Igalia after almost 6 years since I left which, as you might imagine, feels to me very much like “moving back home” too: I’ll be going back to working in a place I’ve always loved so much for multiple reasons, surrounded by people I know and who I consider friends already (I even would call some of them “best friends”) and with its foundations set on important principles and values that still matter very much to me, both from technical (e.g. Open Source, Free Software) and not so technical (e.g. flat structure, independence) points of view.

Those who know me better might very well think that I’ve never really moved on as I hinted in the title of the blog post I wrote years ago, and in some way that’s perhaps not entirely wrong, since it’s no secret I always kept in touch throughout these past years at many levels and that I always felt enormously proud of my time as an Igalian. Emmanuele even told me that I sometimes enter what he seems to call an “Igalia mode” when I speak of my past time in there, as if I was still there… Of course, I haven’t seen any formal evidence of such thing happening yet, but it certainly does sound like a possibility as it’s true I easily get carried away when Igalia comes to my mind, maybe as a mix of nostalgia, pride, good memories… those sort of things. I suppose he’s got a point after all…

So, I guess it’s only natural that I finally decided to apply again since, even though both the company and me have evolved quite a bit during these years, the core foundations and principles it’s based upon remain the same, and I still very much align with them. But applying was only one part, so I couldn’t finish this blog post without stating how grateful I am for having been granted this second opportunity to join Igalia once again because, being honest, more often than less I was worried on whether I would be “good enough” for the Igalia of 2018. And the truth is that I won’t know for real until I actually start working and stay in the company for a while, but knowing that both my former colleagues and newer Igalians who joined since I left trust me enough to join is all I need for now, and I couldn’t be more excited nor happier about it.

Anyway, this post is already too long and I think I’ve covered everything I wanted to mention On Moving (pun intended with my post from 2012, thanks Will Thompson for the idea!), so I think I’ll stop right here and re-focus on the latest bits related to the relocation before we effectively leave the UK for good, now that we finally left our rented house and put all our stuff in a removals van. After that, I expect a few days of crazy unpacking and bureaucracy to properly settle in Galicia and then hopefully a few weeks to rest and get our batteries recharged for our new adventure, starting soon in September (yet not too soon!).

As usual, we have no clue of how future will be, but we have a good feeling about this thing of moving back home in multiple ways, so I believe we’ll be fine as long as we stick together as a family as we always did so far.

But in any case, please wish us good luck.That’s always welcome! :-)

Building a SNES emulator with a Raspberry Pi and a PS3 gamepad

Published March 26, 2015 / by mario / 12 Comments on Building a SNES emulator with a Raspberry Pi and a PS3 gamepad

It’s been a while since I did this, but I got some people asking me lately about how exactly I did it and I thought it could be nice to write a post answering that question. Actually, it would be a nice thing for me to have anyway at least as “documentation”, so here it is.

But first of all, the idea: my personal and very particular goal was to have a proper SNES emulator plugged to my TV, based on the Raspberry Pi (simply because I had a spare one) that I could control entirely with a gamepad (no external keyboards, no ssh connection from a laptop, nothing).

Yes, I know there are other emulators I could aim for and even Raspberry specific distros designed for a similar purpose but, honestly, I don’t really care about MAME, NeoGeo, PSX emulators or the like. I simply wanted a SNES emulator, period. And on top of that I was quite keen on playing a bit with the Raspberry, so I took this route, for good or bad.

Anyway, after doing some investigation I realized all the main pieces were already out there for me to build such a thing, all that was needed was to put them all together, so I went ahead and did it. And these are the HW & SW ingredients involved in this recipe:

Once I got all these things around, this is how I assembled the whole thing:

1. Got the gamepad paired and recognized as a joystick under /dev/input/js0 using the QtSixA project. I followed the instructions here, which explain fairly well how to use sixpair to pair the gamepad and how to get the sixad daemon running at boot time, which was an important requirement for this whole thing to work as I wanted it to.

2. I downloaded the source code of PiSNES, then patched it slightly so that it would recognize the PS3 DualShock gamepad, allow me define the four directions of the joystick through the configuration file, among other things.

3. I had no idea how to get the PS3 gamepad paired automatically when booting the Raspberry Pi, so I wrote a stupid small script that would basically wait for the gamepad to be detected under /dev/input/js0, and then launch the snes9x.gui GUI to choose a game from the list of ROMS available. I placed it under /usr/local/bin/snes-run-gui, and looks like this:

#!/bin/bash

BASEDIR=/opt/pisnes

# Wait for the PS3 Game pad to be available
while [ ! -e /dev/input/js0 ]; do sleep 2; done

# The DISPLAY=:0 bit is important for the GUI to work
DISPLAY=:0 $BASEDIR/snes9x.gui

4. Because I wanted that script to be launched on boot, I simply added a line to /etc/xdg/lxsession/LXDE/autostart, so that it looked like this:

@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@xscreensaver -no-splash
@/etc/sudoers.d/vsrv.sh
@/usr/local/bin/snes-run-gui

By doing the steps mentioned above, I got the following “User Experience”:

  1. Turn on the RPi by simply plugging it in
  2. Wait for Raspbian to boot and for the desktop to be visible
  3. At this point, both the sixad daemon and the snes-run-gui script should be running, so press the PS button in the gamepad to connect the gamepad
  4. After a few seconds, the lights in the gamepad should stop blinking and the /dev/input/js0 device file should be available, so snes9x.gui is launched
  5. Select the game you want to play and press with the ‘X’ button to run it
  6. While in the game, press the PS button to get back to the game selection UI
  7. From the game selection UI, press START+SELECT to shutdown the RPi
  8. Profit!

Unfortunately, those steps above were enough to get the gamepad paired and working with PiSNES, but my TV was a bit tricky and I needed to do a few adjustments more in the booting configuration of the Raspberry Pi, which took me a while to find out too.

So, here is the contents of my /boot/config.txt file in case it helps somebody else out there, or simply as reference (more info about the contents of this file in RPiConfig):

# NOOBS Auto-generated Settings:
hdmi_force_hotplug=1
config_hdmi_boost=4
overscan_left=24
overscan_right=24
overscan_top=16
overscan_bottom=16
disable_overscan=0
core_freq=250
sdram_freq=500
over_voltage=2

# Set sdtv mode to PAL (as used in Europe)
sdtv_mode=2

# Force sound to be sent over the HDMI cable
hdmi_drive=2

# Set monitor mode to DMT
hdmi_group=2

# Overclock the CPU a bit (700 MHz is the default)
arm_freq=900

# Set monitor resolution to 1280x720p @ 60Hz XGA
hdmi_mode=85

As you can imagine, some of those configuration options are specific to the TV I have it connected to (e.g. hdmi_mode), so YMMV. In my case I actually had to try different HDMI modes before settling on one that would simply work, so if you are ever in the same situation, you might want to apt-get install libraspberrypi-bin and use the following commands as well:

 $ tvservice -m DMT # List all DMT supported modes
 $ tvservice -d edid.dat # Dump detailed info about your screen
 $ edidparser edid.dat | grep mode # List all possible modes

In my case, I settled on hdmi_mode=85 simply because that’s the one that work better for me, which stands for the 1280x720p@60Hz DMT mode, according to edidparser:

HDMI:EDID DMT mode (85) 1280x720p @ 60 Hz with pixel clock 74 MHz has a score of 80296

And that’s all I think. Of course there’s a chance I forgot to mention something because I did this in my random slots of spare time I had back in July, but that should be pretty much it.

Now, simply because this post has been too much text already, here you have a video showing off how this actually works (and let alone how good/bad I am playing!):

Video: Raspberry Pi + PS3 Gamepad + PiSNES

I have to say I had great fun doing this and, even if it’s a quite hackish solution, I’m pretty happy with it because it’s been so much fun to play those games again, and also because it’s been working like a charm ever since I set it up, more than half a year ago.

And even better… turns out I got it working just in time for “Father’s Day”, which made me win the “best dad in the world” award, unanimously granted by my two sons, who also enjoy playing those good old games with me now (and beating me on some of them!).

Actually, that has been certainly the most rewarding thing of all this, no doubt about it.

Endless changes ahead!

Published August 26, 2014 / by mario / 2 Comments on Endless changes ahead!

I know I haven’t blogged for a while, and definitely not as much as I would like, but that was partially because I was quite busy during my last days in Samsung (left on the 25th of July), where I wanted to make sure I did not leave any loose end before departure, and that everything was properly handed over to the right people there.

But that was one month ago… so what did I do since then? Many many things, and most of them away from a keyboard, at least until the past week. Main highlights:

  • One week travelling by car with my family all the way down to Spain from the UK, through France, visiting all the nice places we could (and could afford) in the way, which was a lot of fun and an incredible experience.
  • The goal of taking the car to Spain was to sell it once we were there and, surprisingly enough, we did it in record time, so one thing less to worry about…
  • 2 weeks in Spain having proper “relaxing holidays” to get some quality time off in between the two jobs, to properly recharge batteries. Not that the previous week was not holidays, but travelling 2200 km by car with two young kids on the back can be amazing and exhausting at the same time :-)
  • 1 week in the UK to make sure I had everything ready by the time I officially started in the new company, where I will initially be working from home: assemble a home office in my spare bedroom, and prepare my new laptop mainly. In the end, we (my wife helped me a lot) finished by Wednesday, so on Thursday we went for a last 2-day getaway to Wales (what a beautiful place!) by car, making the most that we were kids-free.

Endless Mobile logoTherefore, as you can imagine, I didn’t have much time for blogging lately, but still I would like to share with the world my “change of affiliation” so here it is: since yesterday I’m officially part of the amazing team at Endless, an awesome start up from San Francisco committed to break the digital divide in the developing world by taking GNOME-based technology to the end users in ways that were not imaginable before. And I have to say that’s a vision I fell in love with since the very first time I heard about it (last year in Brno, during Matt’s keynote at GUADEC).

But just in case that was not awesome enough by itself, the other thing that made me fall in love with the company was precisely the team they have assembled, because even if I’m mostly a technical guy, I still value a lot the human side of the places I work in. And in this regard Endless seems to be perfect, or even better!

So, I’m extremely happy these days because of this new challenge I’m seeing in front of me, and because of the opportunity I’m being given to have a real positive impact in the lives of millions of people who still can’t access to technology as they should be able to do it. Also, I feel blessed and privileged for having been given the chance to be part of such an amazing team of people. Could not be happier at this time! :)

Last to finish this post, I would like to say thanks to my friend Joaquim, since he was who introduced me to Matt in the first place and “created” this opportunity for me. Thank you!

My first week at SERI

Published January 12, 2013 / by mario / 9 Comments on My first week at SERI

So, after almost 3 months of “holidays”, I’ve finally started working on my new job this Tuesday in Samsung Electronics Research Institute UK (aka SERI), where I’ll join a team mainly working in A/V and DTV related stuff while, at the same time, I’ll keep contributing to WebKit and WebKitGTK+.

Samsung Smart TV Unveils New Smart HubAs you can imagine, being the first week means that I mostly spent my time learning a lot of stuff about my new job and the tools I’d be using, as well as setting up my development environment and getting to know my colleagues and the things we’ll be working on.

But for the time being I have to say that my first impression has already been very positive and that I’m enthusiastically looking at the future and what it’s going to be next. Surely it will be a very different experience compared to what I was used to, but in a way that’s precisely what I was looking for, and so that’s why I feel very optimistic and motivated about it.

Also, and besides work related stuff, being a new resident in the UK also means that I had to spend some time doing some additional things, such as creating a bank account, getting a UK-based SIM card and starting to look for a place that should become our permanent residence in 2-3 months time, once my wife and my children move as well to the UK (they’re still in Spain), hopefully before Easter. Fortunately, being a EU citizen simplifies a lot the whole thing of coming here to work, since I don’t need any VISA or the like. Just my Spanish ID and/or Passport are more than enough.

Anyway, I’ve just arrived in the UK on Monday and started working on Tuesday (yeah, I love having big margins) so still much to do left, but I’m already on my way so it’s a matter of time that we are settled here, and that we start living the “English adventure” all together again.

But in the meanwhile we’ll have to live with me visiting them every 2-3 weeks and the typical audio/video conference tools.

Can’t wait!

Moving On

Published November 19, 2012 / by mario / 14 Comments on Moving On

Two months ago it was an important day for me. It was the day that I finally told my partners at Igalia that I’d be leaving the company, after almost seven years. It hasn’t been an easy decision to make and so this hasn’t been an easy post to write either… yet one I’d like to write anyway.

But let’s push the rewind button for a moment now…

I’ve joined Igalia on November 2005, initially as a trainee while I was finishing my studies of Computer Science Engineering, and got quickly hooked by the company, the people that was part of it back then and the kind of project they were trying to build.

Igalia as a company is one of a kind, you can be sure of it, and I felt enormously lucky for having found it and having been granted with the privilege of being part of it. And best of all… it happened to have its main office in my own town! I just couldn’t believe it…

I even still recall now how many mates of mine in the Faculty were telling me, back in the days of the University, things like “that Linux thing you like so much is not worth it”, “forget about Open Source, you won’t ever make a living out of it” or even “well, maybe there’s a chance for you to work on that, but it’s definitely not going to happen here”.

I have to say I never believed much in any of those statements (well, maybe a bit the last one), but I swear I couldn’t have ever imagined that I’d be able to prove all of them wrong at the same time without even having to move out of the country, let alone the town.

It was too good to be true. But it was true and real… it definitely was real.

And turns out that what started as a 3-month internship in late 2005, became my first permanent job (and the only one so far) when I became a regular employee on February 2006, to finally become a partner of the company in 2010. Not bad.

I worked on many different projects across all these years, from system administration tasks and pure web development to application development over the GNOME and the Maemo platforms, to end up working on what it probably became the most challenging and interesting thing I’ve ever worked on: the WebKit project and, more specifically, the WebKitGTK+ port.

Additionally, I also met a lot of awesome people while there, both inside Igalia and outside (e.g. at conferences), in some cases  becoming closer to “actual friends” than to “just work mates”, which is yet another great thing I will always feel lucky and grateful for.

In other words, I grew up there, both at the professional and the personal level, and I feel endlessly grateful for that. I’m sure my life wouldn’t have been the same now without that stage in my life, so I don’t have more than good words and thoughts about it.

However, and even if I still think Igalia is an awesome place to be part of, I’ve been lately feeling like I needed a change, to try something new, to move on…

I’m not sure about how much that could be related to the fact that my life is now quite different than seven years ago, and that perhaps my priorities could have shifted now I have my own family, but the fact is that at some point I very clearly saw that I would need to try something else, to change some things and patterns in my life, kind of a “fresh restart”.

And after so much thinking, I suddenly realized such a  change couldn’t ever happen if I stayed in Igalia, since it would probably require that the company stopped being as it is in some ways. And that’s something I don’t think I should ask for “just because I felt that way”. That would be too selfish, don’t you think?

So I made the only decision I thought it made sense: to quit.

Sure it was hard, and even tough at some moments, to make such a decision. But once I made it for real, I have to say I felt very well about it, as if everything was making sense once again, as if the puzzle I was trying so hardly to solve was finally complete.

In any case, this doesn’t mean I want to work on something completely different either. In my lollipop world, my plan is to keep working around the Open Source world as much as possible, hopefully also around GNOME and WebKit, the two platforms I learned to love during these years. Well, actually for the case of GNOME I must say it’s a platform I already loved before joining Igalia, but I can’t deny that being part of that company played a major role to help me get more involved on it, so that’s why I think it deserves some credit.

Fortunately, I’m a lucky guy and I can already say that, just two months after making that decision and starting looking for new opportunities, I already found a job where I think I’ll be able to keep working in what I love (see paragraph above) while, at the same time, being also able to try something different and new compared to what I’ve done so far.

Additionally, I think this new job will also help me find answers to the questions that have been crossing my mind lately, let alone learning new stuff… I’m sure I’ll learn a lot of new stuff as well, something I already can’t wait for.

Anyway, I won’t start working there until January, so let’s go step by step.

First I needed to write this post to tell the world about my new situation (check). Second, I need to use these “two months in nowhere” to re-organize my life and arrange many different things related to the short-term (work in progress). Finally, I’ll start that new stage in my life and finally announce here where I’m going to, something I’d rather keep for another post.

Surely I know all this will mean big challenges for both me and my family (we’ll be moving abroad, to begin with), but those are challenges we’re willing to face and can’t wait for. In a way, I kind of feel like I did 7 years ago right before joining Igalia, when I just finished my studies at the University and still had no clue what I was going to do with my life. Back then, the future looked uncertain and full of opportunities at the same time, and if I now look backwards I can clearly see it was even better than what I’ve would ever have expected. Really.

And you know what? That’s exactly how I feel right now, and that’s a feeling I’m liking a lot. And believe me, I’m pretty much aware that my current situation (married and with two children) is quite different compared to 7 years ago. Yet it doesn’t scare me well enough not to feel thrilled about this new stage in our life, a stage I’m already eager to deal with.

So it’s time to move on. I won’t ever forget the great time I had at Igalia, all the people I met here and all the good things that being part of such an special company brought to my life, but I also think now it’s time to look forward and focus on the future.

I have the most amazing family in the world and we’ll be together on this through thick and thin, so I’m already sure we’ll be fine. It’s just a matter of time we’ll get there, so what else can I ask for?

Just wish us good luck. That should do the rest :)

An unexpected e-mail

Published May 11, 2011 / by mario

Today, while at the ATK/AT-SPI hackfest, I received a mail in my INBOX from a well known guy from the GNOME community stating just the following:

Don't know if you read Hackers news, but this one is pretty nice:
http://news.ycombinator.com/item?id=2532790
--
Regards

So I followed the link and I found a nice thread titled “Love in GIT” where people were commenting about something which remind me of one of the last commits I did in frogr, which became my favourite one so far in the project, by the way.

But the big surprise for me came when I realized that the thread was actually about the commit I innocently made last week, when I realized that the so-much-important THANKS file was outdated since almost one year ago, right when I got married, so I decided to update it. Then I understood that there was actually a good reason for the thread to remind me of that change… Yes, I know, sometimes I’m “a little bit too slow” :-)

So I’d just like to publicly say thanks to the misterious-but-well-known-hacker that sent me the e-mail for making me draw a big smile on my face, and to the people commenting in that thread for the so nice (and funny… “make babies”??) messages posted in there.

Thanks!

Update [2011/05/12]: Now it seems the whole thing hit LWN… hilarious!

The family keeps growing

Published January 9, 2011 / by mario / 12 Comments on The family keeps growing

The Family

Quick after-Christmas post to tell the world, now that is not a secret anymore [*],  that Isa, Sergio and me are currently expecting a new member to “arrive” in the family by next summer,  still no idea whether it would be a boy or a girl, but whatever it will be, we’re already happier than ever, suspiciously in a similar situation than almost two years ago, when I told the world about the arrival of Sergio, our first son.

Well… to be honest I couldn’t hide my preference for a girl if you ask me, just in order to get “the perfect couple”, but regardless of that I’m sure I’m gonna be the happiest man in the world. Yes, once again… and this time it’s not just speculation, I already have 2 years of “experience in the field” supporting this assertion, so take it seriously.

So that’s it, won’t write much more because I don’t want to look boring or the like talking about this kind of personal stuff in this blog, but what the hell… it’s the only one I have and I couldn’t avoid using it to share this publicly.

I think that’s all for now, and sorry for the very-likely-too-personal stuff in my blog.

Happy new year!

[*] You know… even in the era of Internet it kind of makes sense to me to tell these kind of news to some people first before broadcasting them to the world.

I told you so

Published August 25, 2008 / by mario / 18 Comments on I told you so

As you might know, two weeks ago I told in this blog that “big news were about to come”… and the time to say what it was about has come, so get ready… steady… go!

I’m going to become a father

I doubt I could express my feelings right now well enough in a blog, so I won’t write a long post about this topic. Just keep in mind that I’m happy as I never was before, and I’m glad to be now ready to tell the world about it :-)

So.. now it’s time to wait. Let’s see what happens in 8 monts time!
