What’s a technology that you think is overhyped?

I’m going to give a sideways answer to this, which is that the venture capital business model needs to be understood as requiring hype. You can go back to the Netscape IPO, and that was the proof point that made venture capital the financial lifeblood of the tech industry.

Venture capital looks at valuations and growth, not necessarily at profit or revenue. So you don’t actually have to invest in technology that works, or that even makes a profit, you simply have to have a narrative that is compelling enough to float those valuations. So you see this repetitive and exhausting hype cycle as a feature in this industry. A couple of years ago, you would have been asking me about the metaverse, then last year, you would have asked me about Web3 and crypto, and for each of these inflection points there’s an Andreessen Horowitz manifesto.

It’s not simply that one piece of technology is overhyped, it’s that hype is a necessary ingredient of the current business ecosystem of the tech industry. We should examine how often the financial incentive for hype is rewarded without any real social returns, without any meaningful progress in technology, without these tools and services and worlds ever actually manifesting. That’s key to understanding the growing chasm between the narrative of techno-optimists and the reality of our tech-encumbered world.

Judging from my recent statuses I post about the AT Protocol and my side projects. I'm also into self-hosting, infrastructure as code and embedded development

Regarding pricing: in the UK Octopus Energy is very popular among people with solar panels and/or electric vehicles by offering many different tariffs that work well for their use case. They also offer good API for people who want to setup their own automation

I dont think its an accident that pretty much all the new appviews we start to see on atproto are less about communications and more about sharing public data in some structure, whether that is book reviews, recipes, linktree clones or pastebin clones

I miss when telling someone I liked computers we ended up talking about the tech. I can still do it today but I need to be very selective and run away from people who want me to work on their questionable startup idea, sell me a NFT, show me ads, live in a virtual reality or talk with a chatbot

I have used it in a toy project for a while and it has always been a very nice experience, especially as a developer not familiar at all with JavaScript frameworks. The only drawback I see is that I'd like to take a local-first approach and I cannot do that if all my logic lives on the server

lots of talk about how verification ought to work here. I’m pretty wary of the me dot workplace dot com approach — for me personally, I don’t want my employer owning my social media presence and I’m pretty sure they don’t want that appearance either, especially when I’m shitposting

Is there anything preventing to link multiple domain names to the same account? If we go with the idea that verification is done via domain name you might want to verify that you both are part of the Bluesky team (with paul.bsky.team) and that you own your personal domain

I’ve done Advent of Code a couple times in the past but it’s no longer my thing. 
#DecemberAdventure is a cool alternative.
I have a few features I’d like to add to my tool to optimise the use of our solar/battery system. Let’s see how far I can in December

Users aren’t interacting directly with the firehose. Is there anything preventing who runs the app view from injecting ads into the feeds? App view is costly to run so switching to a different one is possible but not that easy

My favorite LA fact is that it used to have an amazing tram network, but then the car companies bought it, dismantled it and sold the land in small chunks so it could never be reassembled, ensuring that cars would become the dominant mode of transport in the city.

Recently I listened to changelog.com/shipit/130 and it also covered the costs to run all the infra. According to the show notes: “One correction about the cost to run Hachyderm. Preston said it’s about $600/mo and after the interview emailed me to let me know it’s closer to $1000/mo”

This is a really good analysis comparing the ActivityPub approach to decentralisation with Bluesky/atproto. I might quibble with some details, but overall it's fair and balanced. Thanks @dustyweb.bsky.social for taking the time to write it!

It’s complicated. Anyone can access the underlying data, which is great, but running a distinct AppView is going to require a lot of resources. It’s great that’s an option but it’s definitely a huge undertaking

More about Bluesky/atproto in contrast to SSB: with SSB we were uncompromising with our decentralization principles, but we also wanted to see how far our technology could go. There were very few radically p2p technologies like us and didn't know its full potential.

Local first is neat and I’m a huge fan of the approach. As anything else it’s not a silver bullet and it’s not a great fit for large scale social media
