  • Amazon is moving away from Android. This move isn’t exactly surprising. It is disappointing though, imo. From my limited testing, I was able to side load an xmpp app on Android and message, voice call, video call seamlessly. In theory, the ability for developers of some types of apps to target Android and reach Windows without writing a touch of Windows-specific or accommodating code was a huge opportunity for open source developers to effortlessly reach cross-platform audiences.


  • There isn’t off the shelf software to run things like Reddit, and the work to make that happen is pretty staggering. That isn’t to say there isn’t frivolous spending there - I have no idea.

    Lemmy has been developed since 2019 and the software crumbled when network-wide users spiked into the ~75,000-ish monthly range when some vocal Reddit users sought greener pastures over the app/api issue last year. A lot of talented new developers contributed scalability fixes that were obvious to them (but not obvious to the main devs), and we now have the largest Lemmy server handling ~10,000 monthly users without crashing. The work that has gone into making Lemmy, an open-source Reddit alternative written in Rust (vroom vroom) handle the waning spike of Reddit users fleeing, was substantial. Look through the lemmy github issues discussions page and merged closed contributions/discussions for that journey. Those people were largely contributing time and expertise for nothing in return. Imagine paying a market rate to all of the people who contributed substantial time into the betterment of Lemmy. By the way, Reddit was open source: https://github.com/reddit-archive/reddit

    Takeaways so far: this is a hard problem, even today with faster software and hardware - and Lemmy needed a diverse set of contributors to get its largest server stable at 10k monthly and ~50k across the network.

    Reddit had 46,000,000 monthly active users in 2012, ~7 years after launch. Reddit has 330,000,000 monthly active users today. My guess is that Reddit employs a lot of smart software engineers that are needed to contribute solutions that allow the site to serve an ever-growing user count without major outages with new features rolled in. Meanwhile, the vast majority of Reddit users will never pay a thing to Reddit and it isn’t a good platform to deliver advertising through.

    My point: It is easy to gloss over the staggering amount of work, talent, and skill that goes into supporting a site that operates at this scale. Reddit is around the 10th largest site in the US (8th if you exclude search engines) and 12th globally excluding search engines.





  • My perspective…in the US, EVs are at the tipping point of displacing ICE on cost and practicality. Battery research plus scale production of batteries will only push that forward from here. Average car in the US is ~13 years old. If we’re looking out 15 years to the entire US fleet of cars transitioning to EV, that’s a staggering change in energy delivery…largely paid by joe six-pack buying their next car. More on that in a minute.

    I have no idea where battery recycling/reuse will end up, or whether vehicle/grid storage will play out, but I am fairly confident that there is economic value that will be extracted at the end of the car’s lifespan or the battery pack’s lifespan in that car. So…joe six-pack’s rational big battery EV purchase today not only completely rewrites US energy consumption in the next decade, it bought enough grid storage to meaningfully push through intermittency concerns of renewables.

    Meanwhile, in my area of the country that has extensive mass transit networks, the outlook is bleak. My state subsidizes mass transit that primarily takes residents to another state for work, where they pay taxes to the other state, then primarily consume services in the home state. The federal government takes way more in taxes than it sends back to the state in support or services. Occasionally, federal democrats take control and send a bone, that gets yanked as soon as Republicans are back in. My state and the public transit agency get starved, service diminished, more cars. Rationally, the other state should contribute some of those tax collections to my state’s mass transit, for efficiency, fairness, and to keep cars off the road, right? Instead, the other state imposed a gas tax that it refuses to apply to supporting transit agencies in surrounding states that send workers.

    I don’t see things getting better for mass transit in my neck of the woods. Big battery EV adoption might not be ideal, but at least it drives decarbonization and convinces masses of unsuspecting people to fund batteries that have lasting value.









  • The rise of distributed computing was at a time that CPUs didn’t really throttle down. CPUs in general were just a lot more power hungry. But if you had to leave the computer on for some reason and had spare CPU cycles, it made sense to contribute them to a distributed computing project - the power was being spent anyway and it seemed like a good cause. Today, modern CPU sip power and throttle down and you are actively driving power consumption by taxing the CPU. There is a much less favorable cost/benefit equation today, but in terms of the cost of the power consumed AND the climate cost of the power consumed.


  • I don’t use SimpleX, but it’s hard to argue against a well developed open source privacy focused messaging app. There are a million “privacy-focused” messengers out there with various flaws around security or sustainability. Matrix is great but the goals seem a little different. Plus, it wasn’t that long ago that Matrix was struggling to find funding.
