I published this book to help developers to understand and use Docker.

It is not targeted to SysAdmins, is aimed to Developers that want to get an operative know how by examples very quickly, and easy to read.

  • University classes are restarted, and I fixed my tower.

For the Cloud computing degree this semester VMWare is used intensively.

I have a dedicated tower with an AMD Ryzen 7 processor, a Samsung NMVe drive PCIe 4.0, which provides me a throughput of 6GB/second (six Gigabytes, so 48 Gbit/second), SAS drives and SATA too. It’s a little monster with 64 GB of RAM and 2.5 Gbps NIC.

It was not starting.

The problem was in the Video card, which made loosely contact to the motherboard.

I had to disconnect everything until I found what it was, but after moving the video card to another PCI slot, it worked.

I knew it was some sort of short circuit / bad contact as the fans were turning for a second and turning off immediately.

After this, the computer works fine but it will poweroff in about 4h and 12 hours. I’ve been testing and removing each component until I believe is the PSU. I’ve ordered a new one from a Dutch provider with web store in Ireland that my former colleague Thomas showed me one year and half ago.

Since England leaved the EU, it is impossible to buy from amazon.co.uk without experiencing problems in the border and delays.

If you want to learn how to assemble a PC, fix the problems and upgrade your laptop, I wrote this book:

If you are curious about what I use in my day to day:

  1. A tower for developing and reading my email, with Linux, Intel i7 7800X (12 cores) and 64 GB of RAM, with Nvidia graphics card
  2. A tower for holding Virtual Machines, with Linux, AMD Ryzen 7 3700x (16 cores) and 64 GB of RAM, with Nvidia graphics card
  3. An upgraded HP laptop for programming in the cafe, is a Windows 10, with 16 GB of RAM
  4. Raspberry Pi 4 and 3, from time to time
  5. A laptop for programming, for Work, 16 GB of RAM
  6. A tower for programming, for Work, at the office, 32 GB of RAM
  7. I also had a Dell computer which battery inflated elevating the touchpad, an Acer 11.6 Latop very lightweight which screen died cracked apparently (it’s a mistery to me how this happened as I removed from the bag and it was cracked. That little laptop accompanied me during years, to many countries, as for a while I carried it with me 100% of the time. At that time if the companies I worked for had outages they were losing thousands of euros per hour, so as CTO I fixed broken stuff even in a restaurant. Believe when I recommend you and your teams to use Unit Testing) and a 15.6″ Acer with 16GB of RAM that was part of the payment of an Start up I was CTO for, and which screen flicks intermittently and I managed to fix it by applying a pressure point to a connector, so I managed to use as fixed computer at the beginning of being in Ireland. I was not using it much, as I had two laptops from work when working for Sanmina, a Dell with 16 GB of RAM and Core i7 with two external monitors and an Intel Xeon with 32GB of RAM, heavy weight, but very useful for my job (programming, doing demos, having VMs…).

I’ve assembled all my PC from the scratch, piece by piece, and I force myself to do it so I keep up to date of the upcoming technologies, buses, etc…

  • My students are doing well. Congrats to Albert for getting 8.67 from 10 in his university programming course exams!.
  • Diablo 2 Resurrected is published and I am in the credits :)

I’m in the credits of all our games since I joined, but I’m happy every time I see myself and my colleagues on them. :)

This release includes SubProcessUtils which is a class that allows you to execute commands to the shell (or without shell) and capture the STDOUT, STDERR, and Exit Code very easily.

I’ve used my libraries for a hackaton PoC for work, for Monitoring one aspect of one of our top games side, and I coded it super quickly. :)

They loved it and we have a meeting scheduled to create a Service from my PoC. :)
