It’s known that repeated exposure to allergens can cause allergic symptoms in people previously without them. For example https://en.wikipedia.org/wiki/Bird_fancier%27s_lung https://en.wikipedia.org/wiki/Farmer%27s_lung

I actually seemed to grow out of hay fever when I was in my early 20s. Perhaps coincidentally this is also around the time I developed an allergy to cannabis from overuse. Wonder if they’re related somehow.

DMT also commonly induces visions of elves (the so-called "machine elves"). Having tried DMT several times I can't say it's something that ever happened to me personally but lots of people report seeing elves on DMT.

My phone network provider ran some "12 days of Christmas" promotion last year which entailed a spam email trying to hawk me crap I don't need every single day. When I tried to opt-out they told me it would take a month. I emailed the ICO and the network provider's complaints team and miraculously they were able to remove me from the mailing list immediately.

Same, I finally managed to stick with learning standard notation this year after several false starts and I’m kicking myself I didn’t start earlier. There were a few tough moments where it seemed like I’d never get (learning about key signatures, moving past 1st position) but now I’m starting to get comfortable playing up to the 7th position. It’s so nice being able to just buy a big book of Sor or Giuliani or Carcassi studies or even some Bach transcriptions and play them straight out of the book instead of needing to listen to a performance first and then look at the tab.

The way I look at it is I just need to get through the next year or so. I also don't believe AI is going to replace everyone, but I do believe that a lot of "leaders" are going to make cuts. They all read the same blogs and listen to the same podcasts and once one makes a move they seem to tend to follow each other.

Maybe it's wishful thinking on my part but I still don't see AI replacing absolutely everyone. As someone who I'd say tends to be in the upper 20% of performers but not setting the world on fire I'm not too worried about my job completely disappearing but I am worried in the short term about layoffs and chaos when loads of people are trying to find jobs at the same time.

Isn't this exactly Marx's criticism of capitalism through the theory of alienation? Human relationships get mediated and hidden as relationships between commodities and money.

Mobile digital mapping was already a useful thing though. Even though Apple Maps was initially a failure I still came back to it every so often to see how it was progressing and eventually it ended up pretty good.

Maybe I'm weird but mobile assistants have never been useful for me. I tried Siri a couple of times and it didn't work. I haven't tried it since because even if it worked perfectly I'm not sure I'd have any use for it.

I see it more like the Vision Pro. Doesn't matter how good the product ends up being, I just don't think it's something most people are going to have a use for.

As far as I'm concerned no one has proved the utility of these mobile assistants yet.

I saw the writing on the wall when they recently removed the facility to download your own books. I downloaded all of them, removed the DRM with Calibre, and now obtain e-books through other sources.

The southeast of England is well-off, everywhere else is less so. It has basically always been like this. There have also obviously been repeated hammerblows since 2008, with austerity (which is still happening), Brexit (a remarkable self-own), and then covid (an unprecedented upwards transfer of wealth). The political and economic establishment is also essentially monopolar, a process begun with Blair and now approaching culmination.

People just don’t have the money to spend on things. Wage growth is non-existent and prices have risen dramatically. For my own part I have get a real “we’ve tried nothing and we’re all out of ideas” feeling. All we ever hear on the news is how spending will have to be cut yet again and taxes will have to go up.

Being from Northern Ireland I personally hope for unification with Ireland, although without significant changes I worry nothing much will change as Ireland has its own very similar issues.

I frequently (basically every conversation) have issues with Claude getting confused about which version of the file it should be building on. Usually what causes it is asking it do something, then manually editing the file to remove or change something myself and giving it back, telling it it should build on top of what I just gave it. It usually takes three or four tries before it will actually use what I just gave it, and from then on it keeps randomly trying to reintroduce what I deleted.

Sekiro was so good at engendering this feeling. The first time you fight Genichiro you will probably die within seconds. The next fight it might take you 20+ tries to beat him. And then the last time you fight him you can basically no-hit him.

I actually don't think I've ever had AI solve a non-trivial problem by itself. I do find it useful but I always have to give it the breakthrough which it can then implement.

> The concept of inlined strings with prefixes (called “German Strings” by Andy Pavlo, in homage to TUM, where the Umbra paper that describes them originated) has been used in many recent database systems (Velox, Polars, DuckDB, CedarDB, etc.) and was introduced to Arrow as a new StringViewArray[^3] type. Arrow’s original StringArray is very memory efficient but less effective for certain operations. StringViewArray accelerates string-intensive operations via prefix inlining and a more flexible and compact string representation.

Seems to be nothing more than they were invented at a German university. I spent quite some time thinking it had something to do with German’s sometimes-SOV word order.

In the UK this happens with tax rebates. For the vast majority of people your tax is calculated by HMRC and taken out of your pay and if they make a mistake you just tell them and they will adjust your tax code so you pay less/more tax until it works out.

Some shady companies set themselves up as middlemen and pocket a large proportion of the rebate when you can do it yourself in minutes through an online portal.
