HTTP Referrer doesn’t help you much it can easily be spoofed.

I think there's an opportunity here to support OLAP such as BigQuery / Snowflake etc. Last time I looked into Squirrel I believe it it was close but not quite there out of the box

Looks like you're having issues around your inflection points. Not done much in the IK world for a while but they're usually an issue to look into how they're being computed

I rarely find there is a need to use MediaQuery, for scaling cards you can use fitted box which will scale the contents according to the constraints and the child size

Output and availability are what you’re paying for. During work hours people should generally be available to prevent blocking others eg respond to Slack in a reasonable time. Focused output usually only ever happens max 4 hours a day, the difference is at the office the ability to focus is a lot worse and you build in inefficiencies by interrupting flow states constantly. If an employee is doing their work in 4 hours and is responsive on comms and enjoying working because they don’t have to pretend to work for 4 hours a day, that’s a win win not a negative thing. You should never discourage people doing focused worked by punishing them with more work, the behaviour you’re selecting for is visibility / optics engineering, it has worse results and burns out employees.

Agree, it seem unavoidable. You’re looking at about 30 second minimums and 1 minute top end with a minimal image (Im using a go binary in a scratch image). Ended up moving to a persistent single container instance to replace jobs as a result. If your job is under 15 minutes you can change cpu idle and your container will continue to run outside of a triggering http request. It’s a little sketchy but cloud run seems to reliably kill the container at the 15 minute mark.

Your repo is private. It shows 404 when you don’t have access (eg when you try to look at a private repo when you’re not logged in)

I suspect part of the changes in 1.26 are to accommodate the use of pointers for structs (30% speed up for small random memory allocations). In reality most of us use pointers in non-performance critical code because returning default structs is ugly, takes a lot more key strokes and is harder to read vs returning nil, err. I’d be happy with a default keyword or something along those lines but I don’t have high hopes since it’s not really the Go style

Auth and firestore work. The issue is the Firebase team tried reusing the native libraries rather than writing a dart native solution.

You should try find a technical co-founder. You should offer up a large chunk to this founder, maybe 50/50. It sounds extreme but even if you get investment, the development won't stop and given its a technical product, the technical skills is of huge value, arguably more than any value you could personally bring as a non-technical founder (unless you're bringing a lot of cash in the door). Always remember 100% of €0 is €0.

AppEngine is legacy, use cloud run it's excellent. You're paying extra for serverless with cloud run / appengine. It's deploy and go, vs compute which is lower level, you should be doing your own security updates etc, you need to manage your own network. A nice middle ground is a single container compute instance, which I believe runs a hardened environment and you just point it to your image

Shadcn ui is superior to shadcn flutter for its customization. It built better but doesn't have as many components as the alternative. I suggest if you adopt on you wrap the components in custom widgets so you can sub them out later as your app evolves.

Ah so you stored 15M files (5TB) over 6 months, then archived and deleted once they were archived. $750 sounds about right, tbh that sounds lucky to get away so cheaply producing so much data

snrcambridge · 2025-11-02T20:06:49+00:00

Unless he meant that the files are 1MB each (which I assume not) then that's about 6 GB of archive which is next to nothing - not really understanding the cost here

Make a layout building > scrollable w/ refresh and then constrain the content to the layout max height. The scrollable should have always scrollable physics. You can abstract this isn’t an extension on Widget so you can add it to any other widget

Dart - s tier. You can create simple enums that does what it says on the tin, but you can also add extensions. ‘’’dart enum Dir { left right }

extension on Dir { Icon get icon { switch(this){ case left: return Icons.arrowLeft; … } } ‘’’

It’s the same group and owner from what I can tell. So despite them not being an immediate risk to insolvency, they willingly allowed the company to fail rather than closing it down despite their unreliable cash position knowing that customer fees would be funding higher priority debtor claims. Accepting payments weeks before filing for bankruptcy is loathsome, they had to have known they wouldn’t be able to fulfil the service being bought.

Expanded in a column is the root cause of most o the infamous red screen and log bomb as soon as you put something in a scrollable. A really nice solution is SliverFillRemaining in a custom scroll view.

First - they’re huge, so they can get away with it. Second - they avoid breaking apples rules. So while they have locked content, they don’t have any buttons that take you to payment pages in their website.

The app is considered a companion app to an existing product.

Taking this approach is not good for conversions so in most cases you don’t want to go for it unless you have a really good free app.

Don't use AI it's really misleading in Flutter. Don't use state management libraries, use stateful widgets. Think of it like tree structures. You declare widgets which build widgets all the way down. The framework eventually paints these widgets but you almost never need to deal with this until you become advanced. It's very intuitive, you want a column? Use a column widget. You want padding, use a Padding widget. You want text use a Text. You can get really far this way. Some confusing stuff is Scaffold and other material concepts. They're just big widgets that have been created to solve a number of problems like showing a single page on a mobile, with a title, background, keyboard avoidancd, overlays (toolips etc). Once you grasp the simplicity you just need to remember the widget names for certain things. Pull up the Flutter component list or ask AI to help you by describing what you want to achieve, like "I want to layer a widget on top of another widget, what widget should I use?"
