martinjacobd··on Associations between infant screen use, EEG markers, and cognitive outcomes
Ah apologies. In your first post I read "can not" as "cannot"
martinjacobd··on Associations between infant screen use, EEG markers, and cognitive outcomes
I'm not sure why it would be true that screen time is not a problem for a <1yr old. At about 6-9 months (maybe before) they are able to interact with the screen, and they interact much more with it if it has bright colors and responds to their touch. We would occasionally allow our eldest to use the phone around this age and she would become despondent if it was taken away. So we decided never to do that again.

Of course, a lack of interaction with humans could be a factor too but in our case we were literally playing with it alongside her and she would still get upset if it was taken away.

martinjacobd··on Rolling Stone left out the reason why FBI raided journalist's home
They don't claim to have video of him engaging in the conversation, but they do claim to have a pretty damning picture of him.

To support the idea that it was he who engaged in these messages, they claim that you can only be logged in to kik on one device at a time and have evidence that he was using the device for other purposes around the same time and in the same location as kik for at least one of these conversations.

That's my reading, anyways. Not a lawyer and have trouble with the stilted language in these kinds of things.

martinjacobd··on Doors I touched today (1999)
My experience with caffeine withdrawal is horrible each time it's happened (and I didn't take great care to taper slowly). This is one of my favorite articles about it "Worse Than The Flu": https://thelastpsychiatrist.com/2007/04/worse_than_the_flu.h...
martinjacobd··on Perturbation Theory
Wow thank you for taking the time to write all of this out. I'm glad I said this as it has given me a few new lines of reasoning to look at and study
martinjacobd··on Perturbation Theory
Hmm if I'm understanding this correctly, (and recalling correctly,) there was a chapter at the end of Kleppner & Kolenkow that dealt with this in the n=2 case: Basically assume the solution is a power series and truncate it past x^2. Well, you know how to solve diffeq's like this, so do it and see the solutions. This was offered as a reason why so many things display periodic or seemingly periodic behavior. If the perturbations (x) are small enough to ignore the terms above x^3, then it's just like the spring equations with dampening/forcing.
martinjacobd··on People had to be convinced of the usefulness of electricity
I'm an American, and this is what my mother calls it, though I call it the electric bill.

> I guess it's useful sometimes to know how to engage the 40wpm "actually get every character exactly right without even looking at the cursor" mode to transcribe documents.

Just thinking about this makes my spine straighten and my fingers "get ready" to go to the home row :p

We must have used the same application at my school. Though I think I eventually got to 75wpm with no mistakes (or whatever was allowed by the program--three mistakes a minute sticks in my mind but who can remember). It served me well. I live-LaTeXed my lecture notes and homework in college.

I unlearned the habit of backspacing to my mistake, correcting, and retyping. That has served me well.

I wish we had spent more time on accurately typing \ | ( ) , [ ] { } etc.† It would help me now as I still make simple mistakes with that. On the other hand, it only would've been useful to a handful of us.

† In fact, thinking about this brought up the very nostalgic memory of buying C++ for Dummies and the first program listing in it having a vertical pipe character. I had never seen it, and thought it was an ell at first. Well, that didn't compile, so maybe it was a 1? I didn't know! And the listing in the book had an unbroken pipe but my keyboard had a split one, so I couldn't tell these were the same character.

Eventually, I hit every key on the keyboard and then went back through them pressing shift until I found the right character! That was a feeling of enlightenment!

martinjacobd··on Ethically Sourced Lena Picture
Meh I don't find the man unattractive personally. But I also wouldn't say he's attractive. Different strokes, may a hundred flowers blossom, etc. I certainly don't think it's ethically wrong to show this to people, or at least not for this reason. I do question if it's appropriate for the workplace though. I guess it depends?

But I think it's fairly clear that the point wasn't to be attractive.

martinjacobd··on What is Chess? What to think and for how long
Considering that we don't have any history of chess until more than 500 years after Seneca's death, in India no less, I think it's fair to say that this is yet another example of "ye olde translationes" editorializing and using too much dynamic equivalence. latrunculi, the word he uses in this sentence at the beginning of chapter XIII, must have referred to a different game.

Plus, I doubt most people would really agree with de brevitate vitae. It's the equivalent of "grind culture" but from the first century. Amusing and interesting but probably not congruent with now most people want to spend their lives. (No shame from me if you do want to live your life that way, but it should just be known that this is far from a neutral perspective.) For a more balanced view of otium (pleasure, relaxation, opposite of negotium, business), I'd recommend the letters of Pliny the Younger.

martinjacobd··on The organ as a wind instrument
If you're in the US, you may want to try to find an episcopal church. They seem to be liturgically conservative enough to still have organs but are generally socially liberal enough to be more accepting. Ymmv, obviously.

But I will say that personally in years of playing the organ and asking random churches (including conservative ones) if I could borrow their organs on a quiet weekday, my bisexuality has never come up. And I didn't have to be friends with the choir director either. Once, I attended one Mass and just went up to him afterwards to thank him for playing (it was beautiful) and ask if I could ever practice with it.

I know it's different from many places as I'm in a big city, but at least four organists whom I've known personally are gay. Many churches don't even require you to be religious even to be employed to play the organ there. Randomly on an airplane, I spoke with an atheist music professor who was choir director/organist at a congregationalist church. They didn't seem to care. So I doubt it'd be a big deal if you just want to practice. The choir director at my current (liberal) parish never takes Communion--I don't know if he is personally religious one way or the other, but it seems to be little more than a job to him.

Also, you should try to find some churches where there is more than just "drab church hymns." 20th and even 21st century voluntaries, anthems, and choral preludes are alive and well in certain segments of Christendom. See for instance the churches that Bálint Karosi plays in. I doubt you'd describe his music as "drab." My parish runs the gamut from Palestrina to something from the 20th century at least every Sunday. Just my 2 cents.

martinjacobd··on The bottom is dropping out of Netflix
Gay/lesbian relationships are overrepresented relative to real life in She-Ra, but there is far more than one heterosexual relationship. Off the top of my head there is Bow and Glimmer, Queen Angela and King Micah, Mermista and Seahawk, and Entrapta and Hordak by the last episode.
martinjacobd··on Using the wrong dictionary (2014)
‘Hal, you are here because I am a professional conversationalist, and your father has made an appointment with me, for you, to converse.’

‘MYURP. Excuse me.’

Tap tap tap tap.

‘SHULGSPAHHH.’

Tap tap tap tap.

‘You’re a professional conversationalist?’

‘I am, yes, as I believe I just stated, a professional conversationalist.’

‘Don’t start looking at your watch, as if I’m taking up valuable time of yours. If Himself made the appointment and paid for it the time’s supposed to be mine, right? Not yours. And then but what’s that supposed to mean, “professional conversationalist”? A conversationalist is just one who converses much. You actually charge a fee to converse much?’

‘A conversationalist is also one who, I’m sure you’ll recall, “excels in conversation.” ’

‘That’s Webster’s Seventh. That’s not the O.E.D.’

Tap tap.

‘I’m an O.E.D. man, Doctor. If that’s what you are. Are you a doctor? Do you have a doctorate? Most people like to put their diplomas up, I notice, if they have credentials. And Webster’s Seventh isn’t even up-to-date. Webster’s Eighth amends to “one who converses with much enthusiasm.” ’

-- Infinite Jest by David Foster Wallace
