The Single Biggest Mistake Programmers Make Every Day

I just read Eric Elliot's article The Single Biggest Mistake Programmers Make Every Day.

I believe the single biggest mistake that every programmer makes from time to time is overcomplicating things.

Commit messages guide

I just read the Commit messages guide, a guide to understand the importance of commit messages and how to write them well by Rômulo Oliveira.

Testing ProxyChains with cURL

Today I wanted to test ProxyChains with a SOCKS5 tunnel, which I did as follows:

$ proxychains curl ipinfo.io

This returns JSON which includes the proxy's IP address if everything works as expected, which it did.

For more information on how to use proxychains, see: Subversion proxy: fixed IP address with proxychains

How to use jq in a shell pipeline

If you use the identity filter, '.', you can pipe output of a command to jq, a lightweight and flexible command-line JSON processor, and have it pretty printed. For example:

curl -s ip-api.com/json/ | jq '.'

The above will show information about your current (external) IP address, similar to http://ipinfo.io/.

For more information about jq, see the jq Manual.

Building the latest version of ProxyChains NG

Today I also built the latest version of ProxyChains NG in order to get rid of the "ProxyChains-3.1 (http://proxychains.sf.net)" message the old version of ProxyChains prints to stdout.

Tumblelog version 1.0 released

I just pushed version 1.0 of tumblelog, both the Perl and Python version, to GitHub.

New are the --version option and a [% version %] tag. The latter can be added to the template.

Mudan flowering

Yesterday, I used the PlantSnap app on my iPhone 5 to identify a flowering bush growing in my mother's garden. The program suggested that it was a Paeonia suffruticosa. Today the flower I took a photo of yesterday was more open so I took another photo for this blog.

Refactoring tumblelog

This morning I refactored the Perl version of tumblelog because I wanted to add next and previous links to the day pages. Yesterday, I had done some brainstorming and I concluded that quite a rewrite was required, which was indeed the case.

In the evening I modified the Python version based on the new Perl version. Both versions are available on GitHub.

WD My Passport arrived

Making a backup on OS X

After I had unpacked the Western Digital My Passport I used Disk Utility on OS X to erase and format the drive as "OS X Extended (Journaled)".

Next, I selected the drive in Finder, selected "Get Info", unlocked the settings at the very bottom and turned "Ignore ownership on this volume" off.

Finally, I used rsync in the terminal as follows

sudo rsync -avh /Users/ \
    /Volumes/Orange/Users/

to start a complete backup of all Users data on the brand new Western Digital harddisk named Orange.

Transfer speed of a WD My Passport 2TB drive

When done with the backup of my OS X "El Captain" /Users/ directory the rsync command reported a transfer speed of 34.72M bytes/sec for the WD My Passport 2TB drive (output reformatted to fit):

sent 788.46G bytes
received 13.34M bytes
34.72M bytes/sec
total size is 788.81G
speedup is 1.00

In the afternoon a lot of noisy sheep passed by. I took a photo out of my office window.

WD My Passport 2TB ordered

I just bought an orange WD My Passport 2TB online at MediaMarkt for €79.99. The external hard disk drive will be delivered tomorrow. Somehow my Revolut prepaid credit card was not accepted so I used PayPal to pay instead.

The hard drive is going to be used to make an additional backup of my Mac mini 2014 as I want to do a clean install of macOS Mojave; I am still on OS X "El Capitan".
