That’s not the right way to start at all. You should start with a fresh . • cloverich: Feel little like this is generated and not based on experience. Claude.md should be short. Typescript strict mode isnt a gotcha, itll figure that out on its own easily, imo omit things like that. Peop

Meanwhile, the cardboard box you have forgotten to take to the recycling for • _fat_santa: I have a cat bed1 that’s attached to my desk. It’s got a “monitor arm” and a bed on top. My cat loves to see what I’m doing all day so she will just lay there for hours and watch me work.

Sure there are 0.000001% edge cases where that MIGHT be the next big • Kovah: I wonder so often about many new CLI tools whose primary selling point is their speed over other tools. Yet I personally have not encountered any case where a tool like jq feels incredibly slow, and I

also • nickandbro: I feel like we are just inching closer and closer to a world where rapid iteration of software will be by default. Like for example a trusted user makes feedback -> feedback gets curated into a ticket

She briefly looks at the collections letter that showed up yesterday due to an unaffordable repair she had to pay for on her credit card. Ano • kerblang: Under HIPAA requirements emailing personal medical info is a massive no-no.

Key Discussion Points: • voidUpdate: Is there a practical way to enumerate all the registered internet domains? EG by asking DNS servers for all the domains they know about, and repeating over all DNS servers they know about?
EDIT: appa • ymolodtsov: It’s interesting that while .yu was killed off, .su (Soviet Union) still exists and you can buy them today. • charcircuit: The ICANN policy of removing TLDs just because a country no longer exists makes no practical sense and only serves to break the internet.

I only remembered a couple CompUSAs, Circuit City, and Best Buy selling c • tracker1: They were ok for the price… I think they were probably the most responsible for squeezing every bit of profitability from independent builders though. It really became a race to the bottom, combine • Bratmon: So if they’re never obsolete because you can always get a $99 replacement, where should I send my 486 to trade it for a Ryzen 7?

It’s good to see Apple’s Lockdow • CGMthrowaway: Related somewhat:
On March 23, 2026, the Hong Kong government changed the implementing rules relating to the National Security Law. It is now a criminal offense to refuse to give the Hong Kong poli

It does not matter which language you are using when you make thousands of tiny memory allocations during parsing. https://en.cppreferen • 1vuio0pswjnm7: Been waiting for online commentary about programming to start acknowledging this situation as it pertains to writing programs
Memory and storage are not “cheap” anymore. Power may also rise in cost

The grand, boneheaded naivete to fail to understand that middlemen are an emergent and intrinsic property of free markets in practice. • PaulHoule: “But like people who are good with computers, the models want a terminal, not some candy ass iPad UI.”
