* Auto-Birthday - if you have a contact in your android contacts that has both a mobile number and a birthday in their contact info, you can choose to send them an automatic "Happy Birthday" message on their birthday at a specific time. Can do it with hundreds of contacts. Doesn't use hardly any battery or resources.

* Wrecker - stupid simple "throw a ball at a tower of bricks and try to clear the board" game. High score tables. Made in unity. High battery when in use, No battery use when not playing. Will use internet for high score data.

* GeoNote - Create Geo-fences to generate a notification when you enter a location with your custom text in the notification. My wife is always telling me, "Next time we're here, remind me to only order one piece of toast" or something like that, so I make a note, it pops up the next time we're there and we're both happy. Notes are stored locally. No internet access required. Uses Geo-Fencing which is more battery-friendly than always-on GPS access.

All my apps are free, very privacy-focused and as battery-friendly as possible.

No information leaves your device (other than the high score data in Wrecker).

You have to side-load my apps though. I'm not putting them on the Google Play Store. They're so annoying to deal with! OMG

I recently did things like current events, but LLMs that can search the internet can do those now. i.e. Is the pope alive or dead?

Nowadays, multi-step reasoning is the key, but the Chinese LLM (I forget the name of it) can do that pretty well. Multi-step reasoning is much better at doing algebra or simple math, so questions like "what is bigger, 5.11 or 5.5?"

Use rsync.

Don't fuck over the user base! Your users are what makes a site like reddit good! Don't they know that? Trim the fat (middle-management usually). Get out of the cloud if you're hosting servers in the cloud, move things on-prem. The cloud is great for flexibility, but for cost-savings, on-prem will always win. Whoever is the upper-management that approved the whole "charge for API use" - fire that guy too.

(rant) Too many websites have had upper-management take over and immediately change things that bring the site to its knees. This happens time and time again with new management. They think that they can bring some new life and revenue into the site and in the process, they cripple the product. It happened to evernote, dropbox, tons of great, cheap/free services that "couldn't support the freemium model anymore" so they cut cheap/free access to the product and people just went somewhere else. That's exactly what's happening now. (/rant)

My house is paid off (bought in 1999, paid extra each month, just paid it off a couple of years ago (30-year mortgage paid off in 23 years)) and both of my kids will be finished with college in the summer of 2030, so that gives me around 8 years to save up. I'm not putting any faith in my 401k or any investments. If they pan out, then cool, but having cash-in-hand when I retire is much more comforting.

After retirement, I plan on staying un-injured and not falling for any money-stealing scams for as long as possible. I'll write software when I feel like it. I'll experiment with new tech if and when it's cool enough to pry myself away from chatting up my fellow retirees and drinking excessively.

Then about 5 years ago, AWS suggested that we use the multi-account strategy. I changed jobs and decided to go with Control Tower, AWS Orgs and the multi-account strategy. I spent more time writing automation to supplement and write terraform and python code to build supporting infrastructure to tie accounts together, enable the proper services and networking in all accounts. The automation for build a new account grew and grew and became a behemoth. There's no API for Control Tower and the process of setting up a new account with MFA enabled and all of the bells and whistles enabled is such a pain in the ass that I consider the AWS multi-account strategy not worth it AT ALL anymore I don't care how much it reduces the "blast zone" it's a monumentally stupid idea.

You should try to put all of your eggs into one basket and manage access to your resources inside of IAM instead. Use tags smartly and you'll thank me in the long run.
