jawilson2··on Message from Pope Leo XIV on the 60th World Day of Social Communications
...what a bizarre use of hyphens.
jawilson2··on Vibe a Guitar Pedal
This is really cool. I have a Line 6 Helix, and have wanted to explore something like this. Do you know if there is anything online about doing this?
jawilson2··on 'Askers' vs. 'Guessers' (2010)
They sound like hobbits!

Good lord, is there a way to block someone on HN? What slop...
jawilson2··on The Palantir app helping ICE raids in Minneapolis
> Everyone is ok targeting te immigrant populations

No, we're not.

jawilson2··on Statement from Jerome Powell
We're still fixing the problems from Reagan. The USA and the world will be feeling the aftershocks 100 years from now.
jawilson2··on U.S. mandates more foreign travelers to pay $15,000 visa bond deposits
Agreed, there's nothing like watching someone hike the Grand Canyon or driving through Yellowstone on Youtube.

Like bog shoes?
jawilson2··on 40 percent of fMRI signals do not correspond to actual brain activity
Yep, this is why it's also called BOLD imaging, for blood-oxygenation-level-dependent fMRI. I did my PhD is BME and brain-computer interfaces, but it has been a while since I worked in the field.
jawilson2··on 40 percent of fMRI signals do not correspond to actual brain activity
f is functional. MRIs are basically huge magnets used for imaging. When you apply a strong magnetic field, different tissue types and densities will react differently, and the MRI is basically measuring how those tissues react to the magnet. It is very good for imaging soft tissues, but not so much bone. Someone figured out that you can measure blood flow using the MRI, because blood cells react in a magnetic field, then "relax" at a known rate. Since we can measure blood flow, that is correlated with increased brain activity, i.e. since more neurons are firing, they require more energy, and therefore more blood. So, fMRI is using blood flow as a proxy for brain activity.
jawilson2··on Two recently found works of J.S. Bach presented in Leipzig [video]
I'm sorry, I just can't listen to Bach piano pieces unless Glenn Gould is making strange sounds in the background that the sound engineer can't remove.
jawilson2··on Is C++26 getting destructive move semantics?
> C++ exceptions have huge overhead when actually thrown

Which is why exceptions should never really be used for control flow. In our code, an exception basically means "the program is closing imminently, you should probably clean up and leave things in a sensible state if needed."

Agree with everything else mostly. C/C++ being a "thin layer on top of hardware" was sort of true 20? 30? years ago.

jawilson2··on Two recently found works of J.S. Bach presented in Leipzig [video]
Something I have always been interested about, but sort of afraid to ask because it is a VERY small jump to unintended racism...

Are there any composers from other cultures that come close to doing what Bach (and Mozart, Beethoven, Stravinsky, etc) did? Like, I want to hear the Japanese equivalent of the Brandenburg Concertos or Mass in B Minor, all guns blazing. Don't tell me "well, it's the space between the notes that matter..." just overwhelm me with genius that is self-evident the second the music starts. I have a few theories, but haven't really researched it.

jawilson2··on Voyager 1 is a light-day away by November 2026
Born in 81 here. One of my childhood memories is of watching the broadcast of the flyby of Neptune in 89. I believe it was on PBS, or something similar.

I just looked it up, they had something called Neptune at Night that broadcast from midnight to 9AM. I probably caught it in the mornings before school.

jawilson2··on Swiss glaciers have shrunk by a quarter since 2015, study says
Same. It pops into my head a few times per week that I haven't thought about global climate change recently, and it is because we are dealing with the more immediate thread of hypercapitalism-authoritarian-christofascism, and my neighbors in Chicago are being disappeared nightly.
jawilson2··on Playball – Watch MLB games from a terminal
In baseball you DO differentiate between whether you struck out swinging or looking.

It matters for the pitcher because if you can disguise your pitch well enough that it looks like a ball coming in but is actually a strike, so that the hitter doesn't even try to hit it, that is a great signal.

As a batter, you typically* want to swing at strikes, so you want to know if you are letting hittable pitches go by. From the time baseball players are like 10 years old, you'll hear coaches and parents yelling "be a hitter, don't strike out looking!".

* there are always situations you probably don't want to swing, like if you have 3 balls and no strikes, you usually want to not swing, and assume you'll get another ball and will get walked to get on base. There are a lot of other situations where you do or don't swing, and the strikeout looking vs swinging measures that.

jawilson2··on Microsoft is plugging more holes that let you use Windows 11 without MS account
Are you using a ThinkPad? My work laptop has this issue too, on windows 11. 75% of the time I have to unplug the monitor after waking up the laptop. 20% of the time it works. 5% of the time it has 640x480 resolution, and I have to unplug it again.
jawilson2··on Microsoft is about to launch free Xbox Cloud Gaming with ads
You KNOW that next, the current top tier will have "limited ads" added (at $30/mo), and they will add an ad-free tier at $35-40/mo.

Gamechanger!
jawilson2··on Inflammation now predicts heart disease more strongly than cholesterol
I have always read it as systemic. Which is why low carb diets seem to do wonders for a lot of people's cardiovascular systems, somewhat paradoxically. If you go really low carb (<20g / day), the first week or two you can lose a ton of weight, but much of it is water, which detractors point to as "well, you're not losing fat!" But, imagine what this does for inflammation. That is 7 pounds of fluid you are no longer carrying and pumping against. It's basically a gallon. The first round of keto I did, I lost a ton of weight the first month (~20 lbs), and my blood pressure plummeted to the point where I was dizzy all the time, and I had to supplement with salt and magnesium. I remember a study I read probably 15 years ago where they looked at cross-sections of arteries before and after starting a ketogenic diet, and there was significant reduction in inflammation after just a few weeks, IIRC. I just tried finding it on pubmed, but can't find the right incantation of search terms to dredge it up. There are countless studies like this.

I've been mostly on a keto diet since 2014, and it is probably the most important health choice I've ever made. At the time I worked in Neurology at a Children's hospital, and a keto diet is one of the treatment options for epilepsy. I talked with the clinical dietician at the time, and asked if these kids were having heart attacks in their 20s. On the contrary, much of the department was on the diet, or a low glycemic diet, as was much of the oncology dept. Obviously, this is an N of 1, and I'm not an MD, but every single aspect of my physiological and mental health has improved over the last 10+ years.

jawilson2··on A platform-jumping prince – History of Prince of Persia's 1990s Ports
We did this when I was in a band 25+ years ago. Record the song, quickly burn it to a CD, then drive back to campus in our shitty Honda Civic or band pickup truck and listen to it. It was 90% just to listen to what we made, but hearing it outside of the studio was good as well.

At this same time, this feels like No Speaker Left Behind. Now that I am middle aged and have a nice sound system at home and in my car, I sort of want a mix optimized for THAT! Like, don't hold me back just because we're still mixing for AM radio in a 1983 Pontiac Firebird!

jawilson2··on Austria hails 'brain gain' in luring 25 academics away from US after cuts
I think it is the "Austria hails..." The extra ia/ai in there is throwing off our brains. I had to read it a few times before it stuck.

Contrary.
jawilson2··on Rails on SQLite: new ways to cause outages
> You can easily do 20k writes per second, what is way beyond what most system anyway.

Do you have any resources on this? I'm working on a project with sqlite, with multiple threads writing, and want to squeeze out a little more performance.

jawilson2··on Microsoft to force install the Microsoft 365 Copilot app in October
What would you suggest to my kids that game with their friends and want to play Rocket League or Fortnite?
jawilson2··on Hollow Knight: Silksong causes server chaos on Xbox, Steam, and Nintendo
Same here. Hollow Knight and Elden Ring are the only two games in the last decade that I've put more than a few hours into. E.g I used to love Civilization, but none of them since 4 have done it for me. Same with Simcity2000. I'll play Madden or Fortnite with my kids, but I'm done mentally after 20 minutes.

The last game I liked like these was Morrowind back in 2004 or so. One of the great things about being a parent is sharing these kinds of things with your kids. I've already got Silksong downloaded on our Switch and XBox to play together when they get home from school in ~1 hr.

jawilson2··on 30 minutes with a stranger
> What about the ad for your kids' school fundraiser? My kids should come home with a flyer for it.

> Or the ad for a used car that your cousin would love. I will actively seek out and research a car.

> Or the poster for the concert at your local community hall. Presumably this physical paper poster doesn't give me malware/AIDS if I look at it or tear off a slip.

My overriding personal objective is to be able to exist without being expected to consume and spend constantly every moment, waking or otherwise. In an ideal world, I should have to give consent to be advertised to, and should be able to operate in public without being bombarded with companies trying to take my money.

jawilson2··on 4chan will refuse to pay daily online safety fines, lawyer tells BBC
English speaker for approximately 43 of my 44+ years on this planet. I have almost no idea what this sentence is trying to convey.
jawilson2··on The Onion brought back its print edition and the gamble is paying off
I did a college visit to UW in 1998, and leafing through The Onion at Union Terrace on Lake Mendota after the tour was one of the deciding factors for me to go there.
