Perenti··on Vagus nerve active during exercise, research finds
Perhaps if I'd put a <sarcasm> tag around that last sentence you would have understood it.
Perenti··on Vagus nerve active during exercise, research finds
This makes a lot of sense to me. I have a disorder of the sympathetic nervous system (CRPS) and a rare cardiac condition (Brugada Syndrome). The inter-relationships between exercise, cardiac arrythmias and nerve pain flares is very strong and complicated.

I take this as further evidence that exercise is dangerous.

Perenti··on Cannabis use disorder and subsequent risk of depression and bipolar disorder
Not always true. I'm prescribed medical CBD, THC and flowers, and pure indica strains help with sleep. Sativa is as you say, it makes sleep worse.

Without "Spectrum Red #1" I sleep in 2 hour shifts. I consume about 0.3 gm (whole herb vaporiser) around 9pm, by 11pm I'm asleep for 6-8 hours. Most importantly, I don't wake wishing I'd died in my sleep.

Note that I'm on CBD, so I don't get "psychotic" side effects.

I also have some 30%THC Sativa that is used to get me going to do things. I can find more reason to push through pain and move more, which in the longer term reduces the impacts of pain and suffering.

I've seen what you've posted about your experience, and if I'd met you in real life I'd have told you "You know you're probably the kind of person who should never use cannabis". I've said that to a few people over the years. Eventually they agree with me. Sadly it's sometimes after they've fucked their lives irrevocably. Cannabis does not do that to _most_ people though, as they use it non-compulsively.

Perenti··on Cannabis use disorder and subsequent risk of depression and bipolar disorder
Your 20 pot heads are most dangerous to sweets and junk food. The alcoholics drive, get angry and start fights.

I'd much rather be in a room with 20 stoners than 5 drunks.

Perenti··on Cannabis use disorder and subsequent risk of depression and bipolar disorder
Remember that word "some" - it's really important. I knew someone who was floridly psychotic and would stab strangers when he smoked weed, until he got an Involuntary Treatment Order and monthly depot injections. He's still got very unusual ideas, but he's not stabbing anymore.

Mental Illness is a very broad term.

Perenti··on Ancient 'Non-Human' Alien Bodies Found in Mines, UFO Expert Says
Seems this one's phone was broken. Seems very like a certain Hollywood alien to me.
Perenti··on SmartKnob – Haptic input knob with software-defined endstops and virtual detents
I have a Roland/Boss GT-100 guitar processor (a big pedal board), which features 8 programmable/assignable open-ended rotary knobs (open ended as they can just be kept rotating without hitting some kind of stop). It would be great to be able to _feel_ hitting certain settings when brushing them with my foot, without having to look at all.

As a musician, I think the introduction of haptics to electric/electronic instruments allows you to move in unexplored aural directions, which is sometimes very musical.

Perenti··on Not a single emperor penguin chick survived spring in parts of Antarctica
Very little in the Sydney Morning Herald is true or factual. It's a player in politics of lies.
Perenti··on Library of Ashurbanipal
For those interested, there are several videos of Dr Irving Finkel from the British Museum talking about the Library of Asshurbanipal on Youtube.

Dr Finkel is a brilliant speaker and fluent in Sumerian, Akkadian and Assyrian writing systems.

Perenti··on MIT engineers create an energy-storing supercapacitor from ancient materials
Surely a fractured supercapacitor is basically a bomb waiting to explode?
Perenti··on ‘The best blueberry’: how a tiny North American fruit took over Australia (2022)
The Northern Rivers area (where Lismore is) has a lot of gullys and valleys, whereas the towns there tend to occupy flatter areas. Winter in the gullys gets bloody cold. The official temperature in Lismore is measured at the Post Office. I grew up in the Northern Rivers, and saw frost most years in the gullys and on the slopes of our farm. We were closer to the coast than Lismore, so they'd get more frosts than we did.
Perenti··on Why is the volume of a cone one third of the volume of a cylinder? (2010)
Is "circular pyramid" intuitive, or is it calculus based? It works for me.
Perenti··on Show HN: Tweak your chord progressions for practice or composition
Hmm.. When working with a I vi IV V in G, it tells me that a substitution of Bm7 for Em produces a ii-V-I in C. It does nothing of the sort! Now a Bm7-5 -> F -> Am is a 2-5 in C, but that's not what it's working with.
Perenti··on The Mellotron, an electronic keyboard of recorded samples, changed pop music
My Boss back in the 80's bought one and I had the job of restoring it. The worst was jam on the drives and heads (a capstan drive and playback head for each key). The magazine where the tapes hang was full of ferrite dust. We ended up using a DX-7 and a Tascam to make new tapes that were not transparent from so much use.

Since musicians favour particular keys, some notes get more use than others, so in theory you'd rebalance the volumes using a pot for each tape.

A truely unique sound though, something about the analogue process just makes it lovely.

Perenti··on Ohio Prison System Bans Java Computer Manual, but Allows Hitler’s Mein Kampf
Prisons in Brisbane, Australia had a library purge about 15 years back. They wanted to remove anything that might excite a rapist or pedo. Among the volumes banned were Tom Sawyer and Oliver Twist.

What wasn't was a hardcover collection of "Romance Stories" which includes a story about a 12 year old raping his 9 year old sister, with no anatomical detail or the grooming process missing.

Censorship is always subjective, but really?

Perenti··on Tested: Where Does the Tone Come from in an Electric Guitar?
I came here to post this, you beat me. I remember an interview where 2 great players swapped gear (one was EVH, I think the other was Jeff Beck) and even on the other's gear they sounded like themselves.

I had the privilege of jamming with Tommy Emmanuel a few times in my younger days. He told me how his brother Phil and himself would find ways to match the sounds off records by using their fingers, as they didn't know about effects back when they were children.

Perenti··on Octopuses are building small “cities” off the coast of Australia (2017)
There was a large group of octopus homes on the sea floor shelf north of Bogangar Headland (east coast Australia) in the late 70s/early 80s. I used to play with the octopuses as a teen.

I had no idea it was a scientifically significant thing though. I wonder if they're still there, as there's been a lot of development nearby.

Perenti··on 50 years in filesystems: towards 2004 – LFS
The article claims garbage collection was invented in the JVM! I wonder what that old DEC-20 was doing when it reported to all terminals that garbage collection was ongoing...

Or what the mark/release garden of eden model of Smalltalk was...

Perenti··on The World Atlas of Languages
Apparently there's only 3 languages in Australia/New Zealand, and they're all sign languages.

No mention of the 200+ endangered languages in Australia, or even Maori in NZ, where it is an official language.

Might be a better site when the data is properly populated.

Perenti··on Kids who get smartphones earlier become adults with worse mental health
To be more precise, it's the model of engagement that bombards the eyes, ears and brain that's the problem. We need social media models that don't require 24/7 engagement.
Perenti··on Kids who get smartphones earlier become adults with worse mental health
Yes, but none of these require you to stare at a phone most of the time. Social media does, as it incessantly screams for your attention.

I don't know anyone other than me who uses their phone for as little as you list (I look at the sky for weather reports) though.

Perenti··on Kids who get smartphones earlier become adults with worse mental health
I've thought about this a fair bit over the last decade. Full disclosure: I'm a smartphone minimalist. I use so little data on my phone I don't know how much I have, it was 100M per month but I think the telco increased it because it didn't fit their plans. I spend $9.99/mth for my phone service.

We evolved to live in the plains of Africa. We evolved to live is small bands of hunter-gatherers who occasionally got together to have huge parties.

Our senses have enough bandwidth to enjoy special mushrooms and to avoid predators. But smartphones can throw far more information at us than that. And for some reason I can't fathom, when your phone chirps or shakes you MUST check it NOW.

I believe that we should look deeper at how these things might affect young brains. Just as THC is mostly harmless for adults, but royally fucks up children's brain development.

Not being a psychologist/neuroscientist I have no idea how to test this hypothesis.

Perenti··on Australia is quitting coal in record time thanks to Tesla
Technically each Australian State is a sovereign entity with His Majesty King Charles represented by the Governer who is "advised" by the State Parliament. The Federal Government many only manages those things that cross State boundaries, like defense, international treaties and borders, once again via the Governer-General who represents the King.

We have an enormous amount of duplication in our governments.

Perenti··on A nasal spray protects against coronavirus including immune-evasive variants
My housemate was part of this study. He noticed his hayfever stopped.
Perenti··on Ask HN: Tools to learn music theory?
I think a great tool for learning music theory is a stringed instrument. By having an instrument _you_ tune you get your ear in tune as well, and you can hear the difference different temperments make.

But ultimately it's about making the music that's inside you, and not everyone needs music theory to do that.

A problem I've seen with pianists and theory is they can get stuck because each key has different fingering, unlike stringed instruments.

Perenti··on The Yamaha NS10 Story (2008)
I had a friend who did post-production psychoacoustics for many big-name acts and labels. He had incredible ears, and could call frequencies by hearing them. His studio was a gear-nerds wet-dream, and had all sorts of high end stuff. He also had NS10s, because they "provide the baseline". It was kinda funny, all these high end monitors, and on the some wall, 6 NS10s.
Perenti··on Gang members hold positions at ‘highest levels’ of LA Sheriff’s department
While I was living in San Diego in 2000, I got talking to some policemen in La Jolla. They told me that having a criminal record is considered a plus when applying for the job, as it shows you understand the criminal mind.

They were probably pulling my leg (or so I thought at the time), but now I wonder...

Perenti··on Australians scour desert for dangerous radioactive capsule smaller than a penny
Australian who has lived in US here. I met a wild mountain lion once, and it was quite scary, less than 3m away, and fortunately as scared of me as I was of it.

Conversely, I've been bitten by red-back spiders, by a bat, many large lizards and goannas, a 4m python, by a wobbygong shark and by a red-bellied black snake. I encounter many more dangerous critters here in Oz than I did in California. I do kind of bring it on myself though, 'cos of my penchant for picking up snakes and spiders.

And don't forget the Cassowary, a confirmed vegan bird that if startled can disembowel you in one strike. Not only apex predators can kill humans. I wasn't aware moose was an apex predator by the way, although they are plainly dangerous.

Perenti··on Australians scour desert for dangerous radioactive capsule smaller than a penny
Probably better to say "and no-one lives around where the capsule was misplaced". It _could_ of been lost in a "built up area" (more than 0.1 ppl/sq km) but statistically it's probably where no-one ever goes except wildlife. It's a HUGE area with very very few people in it.
Perenti··on [dead]
In civilised countries restaurant staff get a decent wage and don't have to beg the patrons for tips. Just saying.
