> The spacewalk was significant for another reason – the twentieth use of a single spacesuit. Eleven taikonauts have worn the suit, which Chinese engineers designed to last at least 15 spacewalks. These five extra spacewalks made it the first Chinese space suit to enter extended use.

I wonder how one-size-fits-all these are. Do smaller Taikonauts find it cumbersome to use? Do larger ones find it uncomfortable?

I think they are recruited to be relatively uniform in physical size in the first place: 160-175cm according to the internet.

this is exactly why strongest model gonna lose out to weaker models if the later ones have more data

for example, i was using deep seek webui and getting decent on point answers but it simply does not have latest data.

So, while Deep Seek R1 might be better model than Grok3 or even Grok4, it not having access to "twitter data" basically puts it behind.

Same is case with OpenAI, if OpenAI has access to fast data from github, it can help with bugfixs which claude/gemini2.5 pro can't.

model can be smarter but if it does not have the data to base its inference upon it's useless.

On the open source library part, you can ask DeepWiki the questions yourself and feed the answers to the LLMs by hand. DeepWiki gives you high quality answers because they are grounded in code and you can check the veracity yourself.

Spot on critical analysis of the blog post "Developers reinvented" by Github Thomas Dohmke which includes such quotes as:

> Many Computer Science (CS) programs still center around problems that AI can now solve competently.

Yeah. No they do not. Competent CS programs focus on fundamentals not your ability to invert a binary tree on a whiteboard. [1]

Replacing linear algebra and discrete mathematics with courses called "Baby's First LLM" and "Prompt Engineering for Hipster Doofuses" is as vapid as proposing that CS should include an entire course on how to use git.

Unfortunately the writer's own understanding of statistics is flawed. For example sample size has not much to do with population size but a lot to do with effect size. For example to demonstrate that a chemical is fatal often a sample size of 1 is sufficient. Population comes into play if there is a large variance of the effect relative to the average size of the effect. You need a good statistical sampling of the population to study the variance but even here sample size if not determined by population size.

Why is 9% for financial services bad? This should cover fees/interest from everything like loans, transactions, mortgages, advice, investing, etc. It doesn't seem that surprising to me that the systems that are the backbone for all the money operations that power the rest of the economy make up about 10%.

Interests you pay is not necessarily all financial services revenue. Only the net interests the industry receives count as revenue. There's a lot of netting going on in finance.

Ultimately, "financial services" is what's downstream of insurance, banking (deposits / money transfers), loans and retirement savings. Also efficient capital allocation and the provision of government services to some extend. Those are things we want, and we want those things to work well.

Yes but it is the overhead. Higher overhead doesn't suggest efficiency.

I can’t wait for this to be available at similar prices for a single family home. Add in solar and a relatively small propane powered backup generator (harbor freight) for extended outages, and for $15k I could be completely off grid. Yes this could be implemented at the grid level, but when it’s at my house, I can crank my AC as low as I want whenever I want. Living in AZ, that’s a massive selling point. The disruption is about to be huge. If everyone in Phoenix suddenly goes off-grid, the power company is going to be stuck with a massive capital investment it can’t pay back. Unfortunately my power company is also my water company, and they will likely just crank water rates. Can’t ever get away from paying the man.

This talks about developer debt, but what about the people who own homes / carrying debt for a home that is possibly far less value than the loan they took out?

They have to show that they are doing something I guess, but really they are way more vunerable to sea drones themselves since they are very dependent on ocean shipping for supplies. So it is interesting that this technology is described as a savior instead of the threat that it truly represents.
