    Some comments not addressing your question: I think you are holding climate science to a far higher standard than the other physical sciences. In the physical sciences, blinded exp…

    Drag-and-drop of the PDF file worked for me in Zotero 9 (latest version). I never used this feature before. This would be greatly preferred to my earlier suggestion to get a LLM to…

    Zotero is not just a front-end to BibTeX. Here are some things I like about Zotero off the top of my head: Zotero integrates well with various online services. This I think is Zote…

    I would suggest looking at more powerful file managers. I use Midnight Commander, which isn't perfect, but is far more powerful than what is provided by default and is also extensi…

    I think part of the problem is that the people hiring are looking for shortcuts and won't accept any approach that requires more than a certain amount of time. I've read comments a…

    I'm a mechanical engineer who has written similar tools for work and hobbies. Producing pretty pictures does not mean that the model is physically accurate. Unfortunately, such too…

    Unfortunately, running an online forum has been a pain for a long time. You have to promote the forum to keep it active, deal with various bad actors (historically spammers, trolls…

    A spell checker, grammar checker, and tutor change a relatively small fraction of the writing, preserve the writer's style/voice, and rarely introduce errors that are hard to detec…

    Recommender systems for papers tend to be pretty bad, so there's a lot of room for improvement. I'll use Semantic Scholar as an example. I have a bunch of folders in what they call…

    I also use a unique email address for Hacker News, and I get no spam to that address. The (different) address I use for the HN jobs threads gets only spam, though.

    Are you loosely paraphrasing here? The closest thing I could find by Scott Adams was "Whenever you have a lot of money in play, combined with the ability to hide misbehavior behind…

    I had a similar experience before [1]. I fully agree that too many interview tests select for dishonest people. [1] https://news.ycombinator.com/item?id=35496976

    Unfortunately, when managers expect a certain throughput, solutions like this often appear. I saw similar systems when I was a patent examiner at the USPTO. From what I recall bein…

    Getting Western researchers to not ignore papers published in languages other than English is a serious uphill battle. During my PhD, I tried to do a truly global literature review…

    I don't think I experienced discrimination during admissions either. Off the top of my head, I don't know any US citizens who told me that they wanted to go to grad school but were…

    As a US citizen with a PhD, I didn't experience any clear discrimination in favor of foreign students during grad school. I think the main reason so few US citizens get PhDs is bec…

    Even if it wasn't a large size, it likely wouldn't be great. During my PhD on sprays, I did some (unpublished) experiments using isopropyl alcohol to reduce the surface tension. Th…

    Fluid dynamicist here. The word "compressible" has multiple meanings and this might be confusing you. You don't need compressible flows in the sense of high Mach numbers. There are…

    I think the type of speed that you're referring to is different from the type of speed the linked article is referring to. I'm not sure what the best way to distinguish the two is.…
