Interesting idea, and it sounds like you like the results, so kudos. My musical taste tends toward less produced, rougher/lo-fi recordings, e.g. Guided By Voices. So, it follows that I prefer the original recordings. There is one aspe

I found out that the adhesives I've encountered from time to time that remain tacky and easily moved or removed are called "non-hardening" adhesives. This was after using E8000 glue for a headphone repair today.

You can, depending on your definition of "useful". You can buy a cheap laser pointer, take out its lens, and put it over your camera lens. Tape it onto the lens for a temporary janky version or make a 3d-printed mount for someth

Yes, on my Thinkpad I could remap it with Powertoys. It looks like the sibling comments have had issues though. For me, the Copilot key outputs the chord "Win (Left) + Shift (Left) + F23". I remapped it to "Ctrl (Right)&quo

Thanks for making this! I'm very tempted to get one of these to do some ssVEP stuff. Do you have plans to make a 16-channel (or 32-channel?) board in the future? In my area of research, 32 channels tends to be the recommended minimum

Translating a solution from one problem domain to another is called "transfer" in cognitive science. There's some theoretical and empirical work done on the topic of transfer (e.g. https://www.tandfonline.com&#x2F

I found a previous HN submission very helpful: https://evamaerey.github.io/ggplot_flipbook/ggplot_flipbook_... The author builds up plots step by step, showing the changes to the plot along the way. It's really g

Not to take away from some of these comments, but the article does not mention anything about casual observation of the eyes signalling mental health issues. The article is highlighting research on diagnosing disorders of the brain using o

In that case, perhaps "A Book about Creating Aircraft Scale Drawings with Inkscape and Gimp" would be more appropriate?

Agreed. I was curious enough to run the model myself so I used a tool to extract the data. The slope estimate (b=17.24) is not significantly different from zero, p=.437. The data are here: https://pastebin.com/HhWTKZRb

I feel the same way. I think this explanation of the transition has been mentioned on HN before: 1) The Internet was created. Early adopters are generally optimistic about its potential to share knowledge and data, and form communities ar

My non-engineer guess is that a nylon brush would be shaved down pretty quickly by rail contact at typical train speeds, so that it would be ineffective at removing debris after a very short time.

I haven't read the entire paper, but it's here: https://psyarxiv.com/a5fgu The main results are an interaction between Time (pre/post) and Diary condition (3rd person/1st person), t = 2.65, p = .008.

Sure, there is subjectivity in the ways researchers operationalize the concepts that they study. That doesn't mean that their research is not "real science". If the study is of sound design and the result is replicable, it

A 95% confidence interval will contain the true mean 95% of the time (across an infinite number of replications of the experiment/study). For a single confidence interval, you have either captured the mean in your confidence interval,

Mirrors in skylights seems like a very obvious improvement to increase the amount of natural sunlight in a space. It seems adaptable to north-facing top-floor suites. Mirrors could be installed such that the sun would reflect into the sui

Power is also a concern that many researchers do not pay attention to (at least in psychology/neuroscience). If the original study was under-powered, the estimated effect size in that study will be inflated and any replication attempt

There are many ways to study attention and mood. What I took from the press release which appears to be novel (though I've not read the original research article) is that our higher-order representations of facial emotions are able to

It's especially strange since there are good free multi-platform statistics programs. There's R (as other commenters have pointed out) and JASP ( https://jasp-stats.org/ ) which has a similar point-and-click interf

I have found it to be a useful feature that is worth the 1% daily battery life. I prefer it to Shazam/Soundhound because it's passive. I don't have to unlock my phone, open an app, press a button, and wait for the app to re
