This Week I Learned - 2016 Week 23

Last week write-up or you might want to read the whole series.

Calculate the power supply needed for your Power Supply Unit (PSU). It seems that my HP Proliant ML110 G6's PSU of 300 watt seems sufficient enough. Maybe the issue is with the power socket or adapter? Next step, install different operating system to test it out. Or maybe I should proceed on building a HTPC instead? But find the required parts is quite an frustrating process. I've never realize that quite a lot of product, for example, casing is not available in MY.

AMD Athlon 5350 Kabini Quad-Core 2.05 GHz is my favourite CPU processor (or APU to be exact) right now besides the XEON X-series. This is a very unique processor that sits between 5150 and 5370 but that supports virtualization extension (AMD-V). Hence, this processor is suitable for building your own homelab which fully utilizes the quad-cores for virtualization. Furthermore, the power consumption is 25 Watt TDP. However, the motherboard choices for AM1l is quite limited but so far only Asus AM1l-A seems to support ECC Ram or not?

One good example of using this processor is building a pfSense firewall. Why one want to build and setup a homelab? Well, if you want to be a full stack engineer or just having some fun building a machine.

As it's very hard to find a single 5350 in MY. The next best option to go for A4 5000, which have similar features to Athlon 5350 but lower clock speed. The only available APU option right now here is BioStar A68N 5000. While having higher TDP, it's still a preferable choice when compare to Celeron J1800 or J1900 for its AES encryption support and less painful VMWare's ESXi installation.

How to teach yourself programming. Learning a new programming language is never hard, you just have to use it on daily basis and experienced the whole eco-system.

Something more about Perl. The official Perl's Docker image is up (via Reddit). So right now, we can have an isolated Perl environment for customization and development. So many things I want to try out, for examples, Moo (Minimalist Object Orientation), DNSMadeEasy Webservices API, and try to figure out how to define and use constant properly in Perl.

While we're on Docker, it seems the default Docker installation in my Ubuntu 16.04 cannot be executed by non-root user. To enable this,
$ sudo groupadd docker
$ sudo gpasswd -a ${USER} docker
$ sudo systemctl restart docker
$ sudo systemctl status docker
$ newgrp docker # no need to logout and login again
$ docker version

Chromiun OS for Single Board Computers (SOCs). Is time to use back the shelved Raspberry Pi 2.
