Configure Dynamic DNS for IPv6 Addresses with Cloudflare

Thursday, December 1, 2022

In another of my adventures with the Mini PC I converted into a server, I’ve found an interesting situation regarding its use from outside the home network. At first, I only used the services I installed locally, but as time went by, I found things somewhat difficult to do from my work. For example, I thought about allowing only local access to the services running on the Mini PC, but time and some situations made me think about hosting the GitLab instance I use for developments at MCV Software on said server. That GitLab is practically a single-user instance, as the vast majority of projects that are open there are also in our GitHub organization. A week after finishing the initial implementation, I can simply say it has been working excellently. Of course, you should never forget to make backups, but that’s always recommended, no matter where the server is hosted.

Installing RTL8821CE WiFi Driver on Debian 11

Friday, November 25, 2022

Today I will write about a quick and quite specific tip for my setup. I have now configured a mini PC as a server (mainly media, although I will be putting other additions to help at home). The thing is that this Mini PC, which integrates a Celeron J4125, would have internet via WiFi, since I do not want to wire so much (the distance between the router and the place where the server should be is not too long, but it would require a relatively long wire, it is not something I would like for now). The router provided by the internet provider, which is Izzi, already offers dual band WiFi, and luckily the Mini pc also supports it. The idea couldn’t be simpler: WiFi on the 5 GHZ band for the server, and most other devices would use the 2.4 band, to try to avoid interference. The server would run Debian, docker, and a bunch of containers for the services I wanted to set up.

Using BuildContext in flutter from async functions

Tuesday, October 25, 2022

Several Months ago, I started to learn a little bit of Dart and Flutter to investigate the possibilities of both, language and framework, when creating cross-platform applications, although mainly focused on mobiles. The idea of these articles, which I imagine will be much shorter than usual, is none other than to put here things that I have been finding over time and that I have not seen quite clear in the official documentation, which by the way is very good. As I tend to forget a lot of things easyly, I think this could be very useful to my future self.

Listening alejandro's heart from home

Wednesday, October 19, 2022

In yet another update on Alejandro’s development, I’d like to talk about a topic that I think has caused more than a few of us, new parents, some kind of anxiety, worry and so on. I don’t know about everyone else, but we, in particular, have been helped by a device we got online. It’s a portable fetal heart rate monitor. This device, which is practically an amplified microphone (listening at 3 MHZ), allows us to hear, at home, what we can normally only hear when performing an ultrasound. This allows us to listen to the baby’s heartbeat, as well as shows an on-screen estimate of the heart rate that is present.

Some updates about our baby

Thursday, October 13, 2022

Three months have already passed since the date of my last post. In these months many changes have occurred in our family, although they all focus on a single member: our baby. I have also noticed some changes present in us, there is no doubt that the proximity of parenthood completely changes many things and ways in which we see some situations. In my personal experience, I honestly never thought I would use these pages to tell anything about our process now that we will be parents, but life is like that, full of changes, discoveries and growth. And this has definitely been growth. It’s amazing to wake up in the wee hours of the morning (I tend to do it occasionally) and be amazed at how much time is left before our baby meets the world from another perspective, outside of mom’s womb, one that will last a lifetime. I also can’t help but feel excited as we “get to know him” more and more. Because getting to know him starts from now on, and I sincerely believe that following closely every step we take, every advance and change that occurs in the various stages of his development even during pregnancy is one of the best things I have been able to enjoy throughout my life.

Baby: 18 weeks

Thursday, October 13, 2022

Three months have passed since the date of my last post. In these months many changes have occurred in our family, although all are centered on a single member: Our upcoming baby. I’ve also noticed changes present in us, there’s no doubt that the proximity of parenthood completely changes many things and ways in which we see some situations. In my personal experience, I honestly never thought I’d use these pages to tell something about our process now that we’re going to be parents, but life is like that, full of changes, discoveries, and growth. And this has definitely been growth. It’s incredible to wake up in the early morning (I tend to do it occasionally) and surprise myself thinking about the amount of time left for our baby to know the world from another perspective, outside mom’s womb, one that will last their entire life. I also can’t help but feel excited to “get to know” them more and more. Because getting to know them starts from now, and I sincerely believe that following with attention every step we take, every advance and change that occurs in the various stages of their development even during pregnancy is one of the best things I’ve been able to enjoy throughout my life.

Our family is expanding by one

Friday, July 15, 2022

Hi there! Today I wanted to make this post, which I think will be shorter than what I usually publish and completely personal (no tech related stuff for now, sorry). The situation is that I have some news that I would like to share and I can’t help but do so. As of about 6 weeks ago, according to medical studies, Leidi, who is my wife, and I, are waiting for a new member to our family. I still can’t believe this, to tell you the truth. We had been determined for some time that it was time to start thinking about settling down and starting a family. We get along very well, with ups and downs, as every relationship does, but we feel that we have the communication, stability and are mature enough to face our next step in life. About a week ago, at a lab test, we got the news we had been waiting for for some time. Our family, which previously consisted of two people, will now consist of a third member, who has decided to hit the road and perhaps, if things work out as they should, which I hope they will, be able to arrive in this world on his own in early March of next year.
