tmitchel2··on JITX (YC S18) launches general availability and announces Series A from Sequoia
Hoping for the following:

- Fully automated place and routing up to 3d PCB level, with constraints including locked item positions, orientations and board stackup. Most likely ML based and fairly quick and trained on a simulator that takes into account various design rules, realistic physics, etc . Zero input from a GUI.

- Datasheet semantics implemented directly into code / logic and rules checking and analog simulation

- Use typescript, jsx to create the simplest way to implement components and sub circuits. (I know this isn't going to happen)

- Use a cloud package manager so people can share thier sub circuits and ICs

- Interactive heirarcical schematic

tmitchel2··on How to bury carbon? Let plants do the dirty work
Offset enough carbon from deeply buried fossil fuel by capturing it and spreading it in a thin layer over farm land, what could go wrong.
tmitchel2··on Performance Improvements in .NET 7
I think you are correct. The DI container and JSON serialisation are two bigger areas that i suspect would need attention but as you say source generation solves the later and I think there is non reflection DI on the way if not already. I guess you would need to wait for any of the third party assemblies you depend on to allow for no reflection also...still a bit of a wait i think for my use case.
tmitchel2··on Performance Improvements in .NET 7
Lol snap
tmitchel2··on Performance Improvements in .NET 7
Using ASP.NET with AWS Lambda or any other FAAS is a concrete scenerio. Startup time for that is critical.
tmitchel2··on The most damaging farm products? Organic, pasture-fed beef and lamb
Definitely feels like this article was written with a pre formed opinion.
tmitchel2··on Cold-brewing of coffee by picosecond-pulsed laser extraction
So yes still heating? Ah no I see the alternate explanation now
tmitchel2··on Cold-brewing of coffee by picosecond-pulsed laser extraction
Hard to heat something transparent with light radiation, whereas I guess the powder can absorb it
tmitchel2··on React Native 0.69
The lack of Jsx equivalent in c# kills the deal for this use case
tmitchel2··on GraphQL JIT – GraphQL execution using a JIT compiler
Why not just go with graphql-aot and be done with it, plus it would work on serverless which I guess this wouldn't.
tmitchel2··on Milk alternatives produce up to 4.5x less greenhouse gas emissions as milk
Working with nature emulating it, as in biomimicry, something we so far seem to be terrible at as a human race.

I guess it's a very localised problem because just under 90% is grass fed in the UK. I can Google grass fed beef and get a lot of hits to indicate where I need to shop or I could ask the local butcher.

tmitchel2··on Milk alternatives produce up to 4.5x less greenhouse gas emissions as milk
Definition of strawman.
tmitchel2··on Milk alternatives produce up to 4.5x less greenhouse gas emissions as milk
If you eat meet which has been raised on ground where trees have been felled for the sole purpose of creating that meat then yes the amount of carbon released is going to be insane. Here in the UK (nearly?) all the meat we consume is grown nationally, i.e. doesn't originate from places like the Amazon.

And on the methane front, they eat the carbon in the grass which has literally just captured a bit of carbon from the atmosphere. They fart it up and then it comes back down in a reasonable period of time and goes back into the grass they are grazing upon.

The cycles and definitely complex and opaque but we need to get better at working with nature rather than engineering new ways to ignore the real issues.

tmitchel2··on Milk alternatives produce up to 4.5x less greenhouse gas emissions as milk
Can you explain why cow farming is bad?
tmitchel2··on Milk alternatives produce up to 4.5x less greenhouse gas emissions as milk
100% this. These dairy cows aren't magically unlocking some deeply seated fossil carbon and farting it into the atmosphere. Nature already has a carbon cycle that works in harmony between plants and animals, let's try and work with it and emulate it rather than use even more energy and other resources to produce these highly processed goods. If you are vegan go for it, if you care about the environment stick with milk made from cows which graze on open grass land.
tmitchel2··on Pupils Reveal ‘Aphantasia’ – The Absence of Visual Imagination
My second thought is that this whole thing could be down to a two way road between the neo cortex and the visual cortex. Its all the rage in machine learning / neural net to paint images using just concepts / words so perhaps some of us can so the same thing. Personally I think mine is less a two way road and more a one way cul-de-sac.
tmitchel2··on Pupils Reveal ‘Aphantasia’ – The Absence of Visual Imagination
That was my first thought.
tmitchel2··on Goldman told TWTR Elon’s $54.20 offer was too low but has a sell target at $30
Where can I tick this as the correct answer :)
tmitchel2··on Have economists led the world’s environmental policies astray?
Donut economics book by Kate Raworth - I read this recently and would highly recommend it.
tmitchel2··on Ask HN: Software you hate but can't replace?
There are very good reasons why your I'd is your phone number
tmitchel2··on DynamoDB 10 years later
DynamoDB for me is the perfect database for my serverless / graphql API. My only gripe is the limitation of items in a transaction of 25. I've had to resort to layering another transaction mgmt system on the top of it.
tmitchel2··on DynamoDB 10 years later
They upped it when they're own autoscaler needed the ability to back it down more :-/
tmitchel2··on DynamoDB 10 years later
You choose your consistency on reads. However, Dax won't help you much on a write heavy workload.
tmitchel2··on A Field Guide for the Modern Embedded Engineer
I presume so you can build firmware in the cloud. It looks like another large part of the idea is to support development remote from the device. This could be a clever move considering the state of things at the moment.
tmitchel2··on Why Google Analytics doesn't help to improve your product
I've integrated GA4 (latest version) into my pre-released product. I assume a lot of this can be covered by that latest version, however, I've not got to the point where I can practically test that theory.

Does anyone here have experience with GA4 as an analytics package, is it good?

tmitchel2··on Everything I've Learned from Growing My Startup to 10M Users with $0 in Funding
As a founder mainly working on my own this article resonated with me.
tmitchel2··on AWS Redshift Serverless
My impression is

Athena = Lambda + S3 (what i would call true serverless)

Redshift Serverless = Auto AWS Managed EC2 instances with local storage + S3

Although I could be wrong as I just had a quick 5 minute look at it...

tmitchel2··on Welcome to C# 10
AWS lambda with graviton here I come....
tmitchel2··on Ask HN: Starting a career as a programmer in my mid-40s
Good luck! Your mechanical engineering background will definitely give you good foundation to work from. If you are if the entrepreneurial ilk then definitely advise you to think about problems you had over the past 20 years and to use those connections too.
tmitchel2··on Goodbye CSS Modules, Hello TailwindCSS
Very well written post tbh
