LLMs are great at aggregating docs, blogs and other sources out there into a single interface and there has been nothing like it before.

When it comes to coding however, the place where you really need help is the place where you get stuck and that for most people would be the intersection of domain and tech. LLMs need a LOT of baby sitting to be somewhat useful here. If I have to prompt a LLM for hours just to get the correct code, why would I even use it when the tangible output is just carefully thought out few 100 lines of code!

Assuming an ext-IP (60k ports) can easily represent 100 household if we statically assign ports. Given CGNAT with dynamic port allocation this can easily go up to 5x? That's wildly inaccurate given the core problem is to "target" a small set of users which is based on this geo info. Not sure how well this elephant sits in a room full of engineers solving this specific targeting problem.

Not sure about US, but Indian ISPs are doing this already to conserve IP space given huge userbase. In theory it would work similar to how a NAT gateway works for outbound communication. Skan + geo would be hard nut to crack in India.

A lot of the big ad networks right now instead rely heavily on geo-data

How does this work in today's age where ISPs normally will have at least one level of NATing with ipv4. And given ipv6 with prefix delegation is still far away this should continue to be very imprecise?

Reminds of the old days, when reverse engineering game binaries were a thing. Finding hex strings, no-op'ing if conditions, adding jmp instructions. Many heroes forgotten with time as more and more of software onboarded the cloud offerings. I wonder how much of it is still relevant and in what fields?

This is excellent, kudos to the author. I wonder if pg exposes enough control to develop a tool along with this information which help analyze locks and their effect on queries on a live server.

Moderna vaccine also seems to have similar storage requirements with a high price tag. BioNTech otoh has impractical storage requirements for the third world. AstraZenca's price and storage combiation may open possibilities for distributing this globally.

Scientists already have a precise knowledge of what the human body is made of, is it possible to develop a shot which basically annhilates anything in the body which is not supposed to be there? I mean instead of developing a vaccine which kills xyz vareity of microbes it will destroy everything which is not in human genetics.

Is there analysis on what encryption algorithm was being used? And how the payment confirmation switch works on the malware.

Is it possible instead of patching the OS, to release a patch which patches the malware binary to no-op the payment switch?

Never rolling back makes a lot of sense, and ia often asserted by the fact that many migration frameworks dont even provide rollback facility e.g. flyway. A database migration is a major high risk change IMO and should be well thought through.

I tend to agree with this. First, no I am not against writing unit tests, they are great way to trap regressions. But test driven DESIGN? really?

Do you drive your car (software) by banging against rail guards (unit tests) to reach a destination? They are there so that you do drive off the road accidentally not guide your way.

JRuby 9000 released 11 years ago

So why does JRuby never got as much traction as other jvm langs like clojure, scala, groovy? I have heard good things about the ruby syntax, top that you get unparalleled powers of jvm like gc, cross platform, libs and much more!
