This doesn't make sense: "With summertime temperatures typically -10°C to -20°C". Maybe the negative was mistakenly added, and nobody noticed in editing? 10°C to 20°C would be reasonable for a "forested and grassland pl

I agree with most of the article, but would clarify the following: > For the screen to look smooth, frames have to be drawn at the display’s refresh rate. On the most common 60Hz display, that means 60 frames per second, or about 16.6 mi

My theory was that memory had some form of static store, something molecular like methylation. I hadn't considered something dynamic/temporal like you describe. Would delay line memory be a fair analogy? Information stored in a

I can remember liking girls from the time I was 5. As with neurotypical pre-pubescent boys I had no sexual interest; holding hands was the only physical contact I desired. Around 11-12, some other boys talking differently about girls, not

I'm an aspie, and think my "version" of ASD has a large epigenetic component. I think social emotions that develop through childhood and adolescence happen through epigenetic changes that enable and disable sets of genetic m

I have a domain with an SSL cert. https://solarsi.ca/ I tried posting on /r/sysadmin asking for help testing a bot blocker, but a moderator quickly deleted the post, claiming it was marketing/promoting. Than

How can I attract more of these bots to my server? I want to test my Apache bad bot blocker. It uses basic header fingerprinting and h2 support to filter them. I get less than 5000 hits on an average day, and want a lot more.

Instead of cash, I like debt like mortgage funds. High single-digit returns with low volatility.

The article didn't include the actual power rates. I think the applicable tariff is $3.316/kW of demand + 16.82c/kWh. https://www.scc.virginia.gov/docketsearch/DOCS/89pc01!.PDF Compared to my local

My wife and I have a few rental properties that I manage. They are investments, chosen based on return on investment and equity (ROI/ROE). Maintenance costs were factored into those calculations. We take care of repairs not because

First off, don't block the first connection of the day from a given IP. Rate limit/block from there, for example how sshguard does it. I've seen several posts on HN and elsewhere showing many bots can be fingerprinted and bl

I highly doubt there is no other technically feasible option to block the AI bots. You end up blocking not just bots, but many humans too. When I clicked on the link and the bot block came up, I just clicked back. I think HN posts should h

Since you didn't show your math, I did a quick calculation. .45J/g/C specific heat of iron means .45MJ/tonne. 1811K to melt iron means 815MJ/tonne. 3.6kWh/MJ, so 226.4 kWh should melt 1t of iron.

Concrete mixes have become more complicated over time. Flyash has been around for a while, GU/L is relatively new and seems to set faster, often requiring retarders. Many different water-reducing additives are available. Air entrain

I know. AIKO has been using copper in their BC cells, and LONGi is making the transition. Many TOPCon cell manufacturers are using silver-coated copper pastes, but full copper metallization is unlikely to happen in the next year or two.

Don't start with a 5MW project. Start with a 10-20kW ground-mount project in your back yard. Then build a 100-200kW project before trying MW.

Panels prices bottomed about a year ago below many manufacturer's cash cost, and have gone mostly sideways since. https://www.pvxchange.com/Price-Index If silver stays above $70/oz, prices will likely go up by 5-1

I'm intrigued. I'd like to see an analysis of how this was done. My first guess is they record humans doing the moves, and then map that to the robot movements. Then I'd like to see a teardown of one of the robots to under

Are you saying Haiku is better than Sonnet for some coding use? I've used Sonnet 4.5 for python and basic web development (pure JS, CCS & HTML) and had assumed Haiku wouldn't be very good for coding.

Isn't "I know" just a subjective threshold for the probability of being true? A layman may put that probability at 90%, while I scientist may put the probability at 99.999% before saying, "I know".

I read "Thinking, Fast and Slow" and some of the other references in the article. I found Kahneman's arguments persuasive, however the article makes me re-evaluate those conclusions. When asked what is more probable, I think
