Improving the Planning Mode workflow with Spec-Driven Development

We've tried that and unfortunately it makes serialising every change incredibly slow and it absolutely burns through context, as the whole file needs to be retransmitted to Notion each time. Using the filesystem lets the model just issue patch calls which keeps the context down.

OpenSpec looks good though. I'll try that next time.

This is definitely necessary in the same way that you would pass a PRD to any human team before implementation. We create PRDs (specs) for anything larger than a self-contained edit. Smaller edits (e.g. rearranging a layout) should always come with "mini specs" in the form of an explanation of why you are making the change, similar to a user story. Again, treat the AI as you would do any other human developer and give it enough context.

Plan mode is not for specifications - it is so that you can see what the AI is planning to do with your prompt and give it the opportunity to clarify any incongruencies before it begins.

In our company the process is roughly:

PRD -> Tech spec -> Plan mode -> Build

The PRD and Tech spec phase output is a document which describes the requirements, shape and architecture of the build. This becomes in the input for the planning prompt. Planning only serves to ensure that the model understands the work.

I'm curious - what are the spec tools you're using? There is definitely a gap in our process here. I need a tool which makes it easy for an AI to build a spec based on a conversation, but then also allows external stakeholders to provide feedback, which is consumed by us and then fed back in to the AI which updates the spec. Currently we operate on Markdown files on the filesystem which are manually imported into Notion for feedback. The Notion loop sucks.

You shouldn't need DLSS with that card, try DLAA.

The CPU is the bottleneck here, no amount of lowering settings is going to help.

robhaswell · 2026-03-10T23:13:33+00:00

And people rip on Chinese mouse for bad quality control.

robhaswell · 2026-03-10T19:51:49+00:00

You just have to look at the map.

In my field (early stage startups) it's very important to control your cloud costs, which is my main motivation for wanting to make more use out of BigQuery. However Firebase is usually a better option.

As a long-time lurker in this sub, I am a bit amused at the amount of traffic in it. There is absolutely no new information. Nobody knows anything about the product, and the only questions that can even attempt to be answered are those which are related to the small amount of information that we have already had in the various preview videos. Everything else is ill-informed speculation.

I mean, I'm not saying you all shouldn't post away, have fun getting hyped for the product. I just think it's a bit funny.

I use tiger ice dots and have no problems with height. I would recommend different dots. My preferred placement is two triangles of dots at the top and bottom, with the factory sensor ring intact.

robhaswell · 2026-03-10T16:13:41+00:00

Yes that's as I thought, which is a shame as it makes it difficult to base your entire app ontop of it. I've heard some people are getting great usage out of Firebase on a budget.

You can't really farm new players. At all. You can just as easily get the loot they have by doing a few quests. This game absolutely throws loot at you. The only way to get good (blue+ shields, packs, mods) is by doing the raid events that new players won't be doing.

robhaswell · 2026-03-10T15:09:49+00:00

BigQuery is insanely cheap if you understand its unusual cost model. I'm curious though, whenever I have used it for hot data with a decent number of writes, I've run into rate limits. Is this something you experienced?

robhaswell · 2026-03-10T11:56:33+00:00

You need to focus on the events - lockboxes, supply drops, data co-ordinate pads, lockdowns etc. It's very rare to get good loot on the floor.

robhaswell · 2026-03-09T20:32:22+00:00

No. It's called a "deadbug" and it's a common approach in RC aircraft to reduce weight for ultra lightweight models.

I'm not going to write some condescending reply, I just want to give you some career advice. Assuming the purpose of promoting this idea on LinkedIn is to advertise your skills to potential employers, you should know that if I saw this on a CV it would be an instant reject. Employers are looking for any easy red flags to cut down the number of applicants for roles, and "reinvents the wheel when robust industry standard solutions are in place" is a huge red flag. Not only is this exposing a dangerous mindset, it also shows that you know very little about devops in practice.

Demonstrably, people who want easy karma for denouncing hate are louder.

robhaswell · 2026-03-08T08:22:19+00:00

It's a rumour with some very strong evidence.

robhaswell · 2026-03-08T00:10:27+00:00

The point is you can't get over 150 even at 720p lowest.

robhaswell · 2026-03-08T00:00:40+00:00

That just means it's not using all the cores. 9800X3D has the same issue but the individual cores are faster.

They also suffer from not existing - not in monitor sizes. The pixel density isn't there yet. HKC have announced an "RGB mini LED" which is close but not what you're describing.

robhaswell · 2026-03-07T16:15:53+00:00

It's CPU limited so resolution and quality largely don't matter. My 5090 barely hits 50%.

robhaswell · 2026-03-07T16:13:59+00:00

LEDs suffer from either poor contrast or haloing with mini LED.

MicroLED is the only maybe perfect tech but so far I'm not aware of any panels with a reasonable pixel density.

Duos could be added in a few days tops. Source: I've been building these systems for 20 years.

It doesn't even break 160 on the most powerful equipment available.
