Thoughs and things
Recently I am playing with Chef and I am having fun on some software with a little difference across different VMs. For example, on VM1:
at log.xml:
... verbosity=INFO ...
On VM2 it is set to ERROR, VM3 is set to DEBUG, etc.

Zsh under Ubuntu has a strange behaviour. When you have typed some commands and use up arrow key to look back, the cursor is always at the beginning of the line. This can be solved very easily.

The php stack I am using for blogs and other hosted php websites is from Remi. I am on PHP version 5.6. The memcached plugin was enabled and I never checked its status. I only found out that the memcached is not enabled at all on my websites.
OK I figured this will be a simple task. It is. There are a few things that you need to be cautious about if you are using Remi as php base. The modules will not be loaded magically.

I created an EFI Live USB stick for the minimal ISO of Fedora 22. When I boot from it, grub said
error: file '/images/pxeboot/vmlinuz' not found error: you need to load the kernel first

I want to share with you my personal deployment scripts for some software I use frequently on servers. Currently there are only a few but eventually I will add them and perfect them with more content.
If you want to remove the branding, you could try to edit the following yaml/rb file, but you need to be cautious about the space as yaml is very sensitive to spacing (no tabs allowed). Also, when you do an upgrade on GitLab, those changes will be lost. Be sure to back up the files before you change anything.

EastLink sucks. Somehow in the evenings, they manage to lower the speed of my connection from home to my server at OVH Canada BHS centre. I’ve complained before but this issue is not going to be resolve anytime soon. Since my residence does not support another ISP (BellAliant, namely), I have to stick to EastLink for now. Strangely EastLink connects to other places relatively well, even my server at the west coast in the states. My other server could connect to BHS server in full speed.
So, how do I bypass the speed limit? By installing ShadowSocks at both ends (home and west coast), I could proxy all my web traffic in Firefox or Chrome without problems. What about SSH, SCP or even rsync? After consulting their man pages, I found some programs support http proxy settings (rsync). Some support port binding (ssh). scp support ProxyCommand, which is overly complicated. None of the above features suit my need.

In Unicode 7.0 there will be tons of Emoji icons added. Linux currently by default, is poorly supporting showing those chars. If you want to add them into your system, what should you do?

I know there are many tell-your-IP-address services available, some even have the whois lookup functionality. I found it was unhelpful when it comes to scripting. I made a website, it has more features which curlmyip.com doesn’t have. It could report your IP address for a script-friendly way (direct response). It supports ipv4, ipv6 and SSL access.
