this prompt is actually in claude cli. it says something like implement simplest solution. dont over abstract. On my phone but I saw an article mention this in the leak analysis.

all these flags are findable by pointing claude at the binary and asking it to find festure flags.

I feel like Java does it the best. Golang didn't start with generics so it's a bit odd IMO.

the batteries included approach is the stdlib that can do everything. turns out it’s hard to maintain and make good.

reinforcement learning is all code that was created by coding gig workers through scale ai and similar. I cannot believe it would be very good.

creating plans in claude and asking chatgpt via api to review loop was my strategy this week. I'm not a big fan of codex as a coding harness because it seems to just give up quite easily where claude will search the problem space and try things but I think gpt does a much better job of poking holes and asking clarifying questions when prompted.

yeah i experienced this the other day when asking claude code to build an http proxy using an afsk modem software to communicate over the computers sound card. it had an absolute fit tuning the system and would loop for hours trying and doubling back. eventually after some change in prompt direction to think more deeply and test more comprehensively it figured it out. i certainly had no idea how to build a afsk modem.

If the test is taken on personal laptops it's almost impossible to stop cheating. You can easily take video capture and send it out via 5g modem on a completely separate computer hidden inside of the laptop. Then you can receive answers back in very discreet ways like nearly imperceptible LEDs.

Same reason DRM-data rights management or DLP-data loss protection technologies are rather pointless against determined attackers. Anything that is permitted to be viewed can be copied.

1-3 is too short but they aren’t making new A100s, theres 8 in a server and when one goes bad what do you do? you wont be able to renew a support contract. if you wanna diy you eventually you have to start consolidating pick and pulls. maybe the vendors will buy them back from people who want to upgrade and resell them. this is the issue we are seeing with A100s and we are trying to see what our vendor will offer for support.

they have very strict AML controls as well. For example if you regularly withdraw a few thousand in cash to pay contractors for a house project they may close your account.

Luxury vehicles I've never understood, especially the non Lexus variety. so don't expect me to explain that.

Due to all the people in my fmaily I have 4 cars so I wouldn't go from 1 EV to 2. If the current EV gets destroyed I do think that used EVs are the right way to go and would buy a used one for sure.

They do still feel like throwaway cars. I'm not sure how you can argue they will have a longer lifetime. If the battery dies surely no one is replacing that at cost? It's more than the car is worth. At least with an ICE each part can be replaced in your driveway with a few hundred in tools and the part probably exists locally used or new.

I bought an EV. it's fun to drive and it's affordable to recharge. However, I wouldn't buy another anytime soon. The depreciation is horrible. They are basically destined for a landfill once they no longer work. I can go to a junk yard and pull an engine for my Toyota tomorrow if I need to.

it's too expensive to move with closing costs and realtor fees :( It's almost always better to buy the most expensive house you can if you you still have a way to increase your earning potential in your career. if you could move without a 6% fee and $xx,xxx financial fees it would definitely be better for everyone overall except the industries who have inserted themselves into these transactions

just makes the prices higher... you qualify for a house based on ratio of income to payment. so the demand is heavily influenced by the type of financing available..

Other than natural demand, Australia has a high real estate market due to the tax and a superannuation/pension distortions. Should try to fix those first. (probably impossible)
