I preferred BotW and didn't finish TotK (yet), so I'd definitely start there. It's a simpler game on a smaller scale. TotK can feel overwhelming with the building mechanics and the massive map which also spans the sky and underground.

100% this. Typing speed was never the limiting factor.

That is a great question and I'm struggling to think of an answer. Answers to queries are slightly faster with a LLM and some repetitive tasks can be offloaded, but the most commonly cited LLM use cases of auto-complete and project generators have already existed for years.

Read @tmaker.io blog yesterday and it home. I've often felt frustrated by the people I'm working with and their refusal to tackle problems head on. I'd never really thought of it in these terms, but I realise now that I'm high action and frustrated by low action people. Explains a lot.

Nice - I love to track a game through development so can definitely see a nice community building around in development games. Get on the journey with the creator as it moves towards release.

Interesting read, albeit a biased source. This line is key "agents are still only capable of handling modestly small-ish to medium-esque tasks at a time". I suspect the 80/20 rule to bite pretty hard with LLM based AI, especially on complex projects, and somewhere in that 20% lies true usefulness.

Some pretty wild stuff in this. Does make you question how useful LLMs actually are though. SDR content is relatively low stakes, transient and measurable. Code is high stakes and only measurable when defective. Suspect the 80/20 rule to bite hard for LLMs & somewhere in that 20% is true usefulness.

Looking nice Thomas and a great game to use for your screenshot. I'm working on a game at the moment, Uneed Games could be a nice place to launch it. Is the plan to only showcase completed games or capture games earlier in the development process to drive Steam wishlists?

Prediction: Software certification is going to become a much bigger industry in the AI era. It won't take many security issues from AI generated code before businesses lose faith and start mandating a higher level of compliance before trusting companies with their data.

Messed up a refactor, tackled too much at once and ended up working in a branch across 48 commits. Seriously, how do people work like that, merging in a tonne of code all at once and releasing periodically. First time I've actually been nervous putting code live in years. Back to CD now πŸ˜…

Reddit post describing problems with AI generated code bases becoming unmaintainable by AI.

Was discussing this the other day. I can see lots of systems like this making it into the wild and relying on senior developers to fix. However, companies replacing junior roles with LLMs will also break the pipeline of junior to senior dev, thus making seniors a scarce and expensive commodity.

Had that experience with Raygun when they implemented what amounted to a 10x price hike - had to go and update a bunch of projects but it became a point of principle. Also a big part of the reason why tools which facilitate self-hosting, like Coolify, are proving so popular.

If you own rokerreport.com or similar you can switch to using that instead of the bsky handle.

Good to see RR on here!

Usual consistency from me. Startup life + side projects + game dev. Not making any money from those side projects but learning all the time, despite moving towards veteran status and close to 20 years in the industry πŸ‘΄πŸ»

The AI examples I see are typically "generate some code to solve a well known software problem" whereas really the job is to take the unique problems of many customers, design a solution which satisfies all of them, integrate that with existing solutions and distribute it without getting in the way.

I do think AI will completely change the way software is built but if it was as easy as outsourcing to an army of bots then all software would already be outsourced to the cheapest labour markets where the concise and accurate requirements of non-devs could be built for a fraction of the cost.

A good thread. The least productive team I ever worked in was also the largest team. The premise of scaling to hundreds of devs (human or artificial) being a good thing is rooted in the misconception that software engineering is production based, whereas it's actually design based.

Qasim Asghar on LinkedIn: #culture #strategy #businesssuccess "Culture eats strategy for breakfast" - a classic quote, but does it hold up? I recently sat down with John Kerr to discuss this very topic. While he…

An interesting question from a recent podcast appearance around culture eating strategy for breakfast. In my experience there's nothing more toxic to culture than bad strategy. Optimists asking realists to take a leap of faith will lead to a culture clash.

10k per day for me, but takes about 1.5 hours of walking to get there. Usually go before work and over lunch. If I miss my lunchtime walk it's a lot harder to achieve.

Yeah, consistency is key but I'm also a sucker for any gamification that encourages that. From Duolingo streaks to GitHub green squares. As I say, I haven't really had the guilt trips as I'm usually in good favour with Duo but I know the guilt tactics definitely exist!

They are VERY good at gamification. So much so that I usually have my streak extended by 07:00 so I've never seen angry Duo. I started doing it to keep my French up and I used to live there so was starting high. Also do Italian and German now, don't think it's great for learning from scratch though.

Been working my way through My Perfect Console by @simonparkin.bsky.social. Great listen and premise. Love the interviews with indie game developers and he's spoken to some of the greats. My games would be: Super Mario World, Champ Manager 97/98, Skyrim, Stardew Valley and Untitled Goose Game 😎
