6502 assembly language for the Atari 2600 (which actually uses a 6507). I've always wanted a lower level understanding of computers, but it took childhood nostalgia to finally motivate me. I also enjoy reading about the original engineers from Atari, Activision, Commodore, etc, so it's been rewarding to dabble in that world.

Sounds interesting! What resources are you using to learn? In case you haven't seen it already, http://8bitworkshop.com/ provides an online IDE.

Thanks! 8bitworkshop is a great resource.

I am currently working through this online course by Gustavo Pezzi called "6502 Assembly Language for the Atari 2600". https://courses.pikuma.com/courses/atari2600 It has been excellent. Just the pace and level of detail that I need. I am lucky to have stumbled upon it.

I am also reading "Making Games for the Atari 2600" by Steven Hugg. Previously I was simply exploring what is available on http://www.6502.org/, working through the Easy 6502 tutorial https://skilldrick.github.io/easy6502/, and checking out YouTube tutorials.

I'm a marketer tinkering with Python. Since Python is so versatile, lots of uses for a marketer like me. I started off with a few Coursera courses going over the basics (Programming 4 Everybody) and read the book with it. Then I tinkered with some basic functions: how to strip a list of URLs for a specific Product ASIN, automating some Photoshop image creation, and searching a 10k row Excel doc for specific phrases.…

You’re probably in a good position to figure out a business idea.

Elixir! I've got such a mixed bag of feelings for that language.

  It's elegant but it's build-times are pretty terrible.

  It has the RPC stuff built-in but I've never seen anyone use it in production and instead folks are doing redis or 
 something else traditional.

  It has elegant process management but it's cloaked in magic (that you have to carefully learn).
To your question - this weekend I'm learning kafka's client protocol (and maybe amqp protocol?) and try to write a transparent proxy of sorts.

Complexity Economics I've been binging books on the topic as well as exchanging dialogs with a colleague over email. Books list: _Completed_ The Origin of Wealth: The Radical Remaking of Economics and What it Means for Business and Society - https://www.amazon.com/gp/product/1422121038/ref=ppx_yo_dt_b... Increasing Returns and Path Dependence in the Economy (Economics, Cognition, And Society) - https://www.amazon.com…

You may like Why Information Grows by Cesar Hidalgo. The principal behind it is called Economic Complexity. It is based on the applications of network and graph theory using export data of a country, region or city as a proxy to its productivity and innovation. I find it pretty interesting.

As a web developer, I'm often ashamed to admit that I knew very little about AI. Especially because I worked on a AI product on my day to day. I was perfectly fine debugging our python code and updating spacy, but had no clue what it was doing internally. So 6 months ago, I quit my job, published a short book, then studied AI. It's funny how so many material makes the vast assumption that you already know so much. Th…

I took the Coursera's Machine Learning course in 2017 just because I had some time then. But I didn't work on any related project, back to square one now. A few weeks back I started to revise the course but it's appears to be boring because I know that I've done it already and I feel that I'll forget it once again.

Can you please share how you started and the projects you worked on?

Earlier quoted context omitted.

The FAA written plus the flying exam are just the bare minimum to make you legal, but not safe. Buying XPlane plus some yoke and throttle quadrant is the best investment you can make when it comes to IFR. Make sure you invest in it.

Yep, totally agree. XPlane is a fantastic idea I'll look in to it. Better than Microsoft Flight Sim?

Yes, it doesn’t look as nice but is much better for IFR. The G1000/GNS 530 are accurate enough that you can actually practice with them.

I’ve been playing with bare metal Raspberry Pi programming and really enjoying it. There are two great frameworks — Circle and Ultibo. The former is in C++, but the latter is in… Free Pascal. Which is kinda weird but kinda fun. Having a Pi boot up and run your application in 2-3 seconds is pretty stunning.

Hold up. Do all the peripherals work?

I mean, it kind of depends what you're looking for. But out of the box, you get:

- HDMI video (I've only tried the first on Pi 4's)

- HDMI sound, PWM sound, headphone sound

- I2C controller/peripheral base classes

- SPI support

- serial logging

- USB controller/hub PnP support, including mouse, keyboard, and gamepads

- FAT support

I haven't messed with networking or wireless of any sort yet. Not needed for my use case, but I believe ethernet is there, at least.

Spanish. It's been the focus of most of my free time for the last 1.5 years and I've seen incredible results. I'm surprised by those who commented that they're learning multiple unrelated subjects at once. Are you learning anything beyond a superficial level? Or is the goal to pique your curiosity on a new subject and then decide if you want to make it your core focus?

I'm one of those doing multiple unrelated subjects at once. For me, it's because I have the time. I'm a teacher, and we're out for summer, so I've got time to focus on several different things. I can do an hour or so of math a day, alternating the various books I'm going through, and give myself an hour of Irish immersion a day (mostly reading) as I'm already at a comfortable B2+ (officially tested) so it's just a matter of keeping it going. Then I can read some in whatever textbook I'm doing of an evening. My other subjects are much more superficial, happening mostly from reading books while I exercise (walking and biking on a stationary bike are perfect for this).

But, really, it's mostly because I have more time and few other hobbies currently (not starting anything new before I move countries in a few months).
