• Is it possible to run and use the last supported version on older devices/systems? Legacy API?

Devices

• Does the app support all screen sizes in both orientations?

Tiny Loader version 1.2.3 is out now. Tiny Loader is the companion Mac app for Tiny Player. The app is now notarized with Apple. This makes it easier to launch the first time after downloading.

Here is a list of development tools I’m using at the moment.

Hardware

• iMac retina 27″ 2015, 32GB RAM
• iPhone SE
• iPad Mini 4
• XBox wireless controller

Software

• Xcode 10
• Blender
• Adobe Photoshop
• git + Sublime Merge + GOGS

Libraries

• C++17 STL
• Dear IMGUI
• STB image
• STB vorbis
• STB truetype
• PugiXML
• LZ4
• pl_mpeg

Notes

• Recent versions of Photoshop have been not so great. Pixelmator development has almost ceased. Considering switching to Affinity Photo.
• Starting to use Blender for 2D vector graphics as well (icons etc).

Number of commits is not a good metric for productivity, project health or anything else really. But let’s pretend! It may be OK as a simple activity indicator…

Here’s a Python script I made that graphs daily commit counts on a git repository by year.

Download the script here. Requires Python 3 and PIL/Pillow.

Usage:

pip3 install pillow
python3 activity.py /path/to/imgui imgui

Output:

The latest annoying update from Dropbox made me look around for an alternative.

iCloud, Google Drive and OneDrive might seem like the obvious candidates but I’d rather avoid them. Why? They are too much like Dropbox. Sooner or later they are going to introduce a similarly annoying UI blunder, crippling limitation or an unfriendly plan.

So I decided to try Syncthing instead. Simple, free, self-hosted, with Linux, Mac and Windows clients. Sounds good…

From a business standpoint it probably makes sense that Dropbox doesn’t offer a pay-for-what-you-use plan but that is exactly what I want. With Syncthing, it’s no problem.

I set up a simple DigitalOcean VPS as a “master” node that’s always online and adding extra storage space is super easy and cheap.

I’ve been using Syncthing for about two weeks now and it seems to be working really well. It is solid software, complete and functional with no extra fluff. Filesystem changes are picked up and synced quickly.

Following the development of the Witness was fun. Jonathan Blow, a very talented game designer, took over 7 years to make it. When the game finally came out, I thought I had seen enough screenshots and read enough blog posts about the process that actually playing it wasn’t necessary.

But one day it went on sale on Steam and I decided to give it a try, just to see if it would run on my iMac at all.

It did. And I got sucked in immediately. From the first minute, it was clear that this was a game for me.

The world of The Witness is vibrant and beautiful. The visual style is perfect. Just the right amount of geometry and texture to make everything clear. Exquisite lighting. I also found it delightful to hear proper footstep sounds for different kinds of surfaces.

The game is designed so that there’s no need for a tutorial, a guide or other hints that would normally be put in a game. In The Witness, those would look out of place. Everything is seamless. No words, no hand holding. You just start playing.

There are several areas on the island, each with a different type of puzzles. The rules are not written anywhere or shown – for each new type of puzzle you need to experiment a little to see what works. Sometimes you get it wrong. The rules you devised worked for the first puzzle or two but not the next one. Go back and think again – same moves, different reasoning.

Generally, the difficulty goes up for each puzzle type as you progress through the area but it is fine to leave and go elsewhere if you get stuck. I was able to finish some areas without much effort, some others I found devilishly difficult. I guess other players could easily have it the other way around because they see and think differently.

Later in the game there are places where you need to combine several puzzle types. This adds more challenge and also acts as a key/lock mechanism to prevent you from going places where you shouldn’t be able to get yet. Find the place to learn what you need and come back later.

Sometimes, after going through a few increasingly difficult puzzles, I’d stumble on one that just made me laugh. A deliberate joke one can only understand knowing the rules and having seen the previous puzzles. This is a nice reminder that the puzzles have been carefuly crafted – not randomly generated.

Running around the island reminded me of orienteering. A person has been there before me, setting up challenges for me to discover and solve.

I was also reminded of OK Go videos. Sometimes it all seems simple and effortless but when you think about it a lot of work has gone into every detail to make it all work. A true sign of a well crafted piece of art.

Excellent game.

I’d love to see a special edition of some sort with developer commentaries in the style of Half-Life 2: walk up to an area, hear a quick clip of Jonathan Blow talking about his intentions and challenges related to that place etc.
