Discrete event simulation frameworks, like SimPy, are a great mathematical way to simulate the environment if wanting to discover better methods of any methodoical staging flow. Elevator scheduling is one example that can be simulated.

The leverage is the trick in the whole equation. During dotcom days the leverage was fine until the cash flow ran out. Then bankruptcies started and the bottom fell out. It appears this is happening again but perhaps the business model will just evolve. Although right now it feels more of the same.

I'm not a sysadmin but I often hear about server failures due to hardware just wearing out. Is there an expected shelf life of the hardware? I would expect for sure on the storage devices. So if that were the case then why isn't there some sore of daemon or system software service that tracks the expected life of the hardware? I would expect that the software would start showing warnings of imminent useful life of devices to expire.

Shareholder primacy is a drain on so many levels. Think of all the R&D that could have been spent instead of buying back shares.

Financial risk management is a great industry for data science. I've been doing it for 15+ years. It is amazing the data rich environment which includes credit bureaus, customer transaction history, call center dynamics, and of course finances. It is a gold mine of opportunity to find new and fresh ways to observe the organization. This is also what makes risk management difficult as well. There is so much to know. LLMs are going to change risk management as it is changing every other industry. It will be interesting to see where it is headed.

larrydag — Sun, 18 Jan 2026 19:12:19 +0000

It works for me. Cathedral is analogous to free software being a religion. It is a theocratic worldview that has a zealous following that must apply the rituals of old. Bazaar is the marketplace. It is supposed to be a efficient market metaphor for software being transactional and not relational.

Is this a perfect metaphor? I think its a rigid way of looking at software on either side. I think it is more grey. I like the merits of both sides.

The US Constitutional government is meant to be slow, methodical and gridlocked. It is supposed to take enormous compromise to get any decision created into law.

Very close. In fact you could still say that it still is competing with Python for users. There is still an active community of developers.

New comment by larrydag in "Spending too much time at airports"

larrydag — Sun, 24 Aug 2025 12:56:29 +0000

While the 1 hour rule is mostly true be careful with discount airlines. Frontier Airlines does do a 1 hour boarding. I've heard of cases that if you are late to boarding, even if half hour ahead of departure, they will not let you board the plane. I'm sure it depends on specific airport agents protocols. My point is I'm not sure you can always use the 1 hour buffer.

I agree. Group channels on relevant topics is very helpful. Especially on technical details relevant to getting work done.

Yet here goes my rant. Nothing can replace a good in-person interaction. Perhaps I'm the old guy in the room. When teams are trying to build something there is nothing like water-cooler talk and banter about the work that helps relate shared challenges. Granted this is going to very specific to organizational needs.

I don't work in software development so perhaps my needs are different than most on Hackernews. I've managed teams in person and remotely. I've found that managing in person is a much more productive way to work.

"If SpaceX can do it, NASA can do it."

Space Shuttle never achieved is core objective and project shelved. Space Launch System is way past deadlines and cost. As far as launching systems NASA has not kept up since Apollo.

I would argue NASA has achieved great progress in Space research. Hubble, Voyager, Mars rovers, Webb telescope have made great advances in discovery. I would have NASA change its core objectives to new research activities.

That would be something. When a AI/LLM can create new axioms or laws that have not discovered by humanity.
