ObjC to work in geometry, metaphysically hurts

The well known Erica Sadun posted something that totally resonates with my experience so far.
If you need just one compelling single example, take CGRect: Swift 2.2 lets you expand this essential structure with methods and properties that let you center on a zero origin, or scale and transform, or add math to combine instances. It’s so practically useful that going back to ObjC to work in geometry metaphysically hurts.
I could have not expressed that better than that!

Postgres on Synology

Image
I own a few Synology NAS, one of them is dedicated to development for various projects. More than once I need to store data into a relational database. Synology comes with MySQL Administration tool (MyPhpAdmin) and the cool MariaDB. It actually also comes under the hood with Postgres. By default, it’s not configured for your consumption. Below you find my recipe on how to get it up and running. If you are not familiar with vi (the editor) then you definitely want to install a package manager (iPKG) that allows you to install what you give for granted on my UNIX OSes. Say nano as for the editor. To do that the best guide ever that I found is already written by @zarino – follow his instructions and you can’t get it wrong. There’s only one piece of information that is missing from that blog post and is for a special case: When you log back into the system the profile that enables all the goodies of the packaging isn’t loaded by default, you can force the loading doing  source /etc/profil…

Zen-inification - The art of decluttering

Image
TLDR: I am decluttering my life. On my own terms.If your span of attention is higher than one sentence, read on and you will see how I got to create my own word "Zeninifcation" as a start to take action against the fact that I have more crap than I need and it is sucking my time just to keep it out of the sight. I don't like clutter. I don't do things I don't like.Even if my wife disagrees, no, I don't have OCD according to this one random article. But I do consider clutter a distraction to my thinking. It's like if you always dress like a slob then that one day you have to dress nicely it feels specially constraining. Or if you normally dress like a New Yorker stock exchange assassin the few days in a row that you are in your PJ feels like after you finished your huge McDonald's burger the first week after you started a diet.Let's dig deeper.I moved from Europe to the U.S.A. about 18 years ago, by the time of this post. At first, as most expats I…

Bring Boxee Box back to life

If you haven't met this beauty when it came out then you have been missing out! It was so forward-thinking and so well designed. As often happens to great acquired products, they are killed for reasons beyond the compressible path to the mere mortals.
I was helping my friend Cristiano in setting up his Synology system along with Plex. And every single time I dealt with Plex I regretted every second of just installing and then figuring out how to remove that cancer from the system. I know that some people out there must have a good experience about that product otherwise I don't understand how they still alive... but over many years that hasn't been me and now Cristiano too :-)
So I was digging in my garage for something that I could have used as tvbox with some Linux distro on it. And that's when I ran in this wonderful piece of tech. Sitting there without love and full of dust bunnies. It booted at the first attempt and the remote battery was still alive!!
Sadly, it woul…
