My take, is that this effect has removed a lot of the micro communications we make - not necessarily random conversations. It’s taken away random moments that may trigger a short small conversation with strangers.

In part it’s taking away the shared experience in public and making it “my” experience.

A misconception is that chess is all memory. If you look at some of the research, it’s learning to remember patterns, not all the moves.

Eg when they tested good chess players on random board positions they were just as good as people that did not play chess.

The mesh in version one lasted just over 12 months.

Repair bill at Apple was 90% of the cost of a new pair.

Truly the worst built product I’ve bought from Apple.

Never again.

Singapore to a tea. Spooky that I had a similar path, Sydney -> HK -> New York -> Singapore. Crescendo-ing up to New York, then off a cliff into a full blow school-like world (but great trains).

Super strange when there are several on the front page, older, with less votes and less comments. To say it’s off topic is a little narrow minded given the current environment

Anecdata- I did this as a 13 year old in the 90s. My old man came upon it after I was repeatedly ending up in hospital in Australia with asthma as a kid. I think there was a presentation in a local scout hall!

I didn’t understand the history at the time - but it stopped me going to hospital, I ended up being able to do a controlled hold (no discomfort) of around 1:30 min and a max hold of just shy of 5 mins.

So for me it had a big impact.

I stopped in my 20s and now I am no where near able to get those numbers.

The App Store is an absolute sh!t hole of an experience. Irrelevant ads, impossible to find anything decent. It’s the internet of 1998 pre google.

It’s crazy you can pay for premium, which is not cheap, and you can’t disable shorts.

The number of times I clicked “show less” and it has zero effect on the number of shorts.

The big problem is that it’s shit and terrible UX. We should stop complicating feedback :)

possible, seems this is done in other modes.

quote - google ai mode:

"DuckDB offers robust capabilities for querying data stored partially on S3, particularly when dealing with Parquet files. This is achieved through several optimization techniques:

Predicate Pushdown: When you apply a WHERE clause to filter data, DuckDB can "push down" this filter directly into the Parquet file scan. If the Parquet file contains zonemaps (metadata about value ranges within columns), DuckDB can use this information to skip reading entire sections of the file that do not contain relevant data, significantly reducing the amount of data transferred from S3.

Projection Pushdown: When you select only specific columns in your SELECT statement, DuckDB automatically reads only those required columns from the Parquet file. This means you avoid downloading and processing unnecessary data, leading to faster queries and reduced S3 transfer costs.

HTTP Range Reads: DuckDB leverages HTTP range headers when interacting with S3 (or other object storage supporting range reads). This allows it to fetch only the necessary parts of the Parquet file, such as metadata or specific column chunks, rather than downloading the entire file."
