Cardiac hypertrophy is not necessarily a bad thing, it can be the result of positive adaptation, such as exercising.

Eccentric hypertrophy (athlete's heart) is the positive adaptation resulting from training the heart. The heart has a lower resting rate and is more efficient at pumping blood. It returns to normal size if training stops.

You'll never reach a state of hypertrophic cardiomyopathy (the bad kind of hypertrophy) with exercise. Its cause is usually genetic.

This appears to be LLM generated and full of hallucinations.

1. Aaron Swartz’s last blog post is a review of the movie The Dark Knight. No entry on his blog has the title "Goodbye, Dr. Spencer".

2. The quote is not present at all in the linked note.

3. The link is wrong, should be: https://www.cs.cmu.edu/~rdriley/487/papers/Thompson_1984_Ref...

4. and 5. are simply extremely generic quotes without any valid source. "Programmers crying in despair" GitHub repo does not exist.

The essentiality of the product is debatable, but ~80% of maple syrup production comes from Canada, 91% of that from the province of Quebec.

China produces ~80% of the world's magnesium. Cobalt comes mostly from Congo.

In the 40-50% range, there is Kazakhstan with uranium and Australia with lithium.

Static linking of LGPL content (thus making it derivative work) only requires that it must allow "modification of the work for the customer's own use and reverse engineering for debugging such modifications".

Making your own code public is not the only way to achieve this.

You can also make available to customer object files and build instructions to recreate your software with the (modified) statically linked LGPL content. (if it's LGPL > 2.1 you have extra requirements: you need to provide all toolchains/dependencies and it must be actually possible to install a modified version on the hardware)

Granted, this is not commonly used but I've used this on some projects where dynamic linking was not available/desired by client.

This looks interesting. Most embedded project I know use ICU/libicu for their unicode needs. As a potential customer I would like to know how does it compare against ICU for performance and code size. Why should I switch?

They are all educational games of middling quality released in the first half of the 90s. Released for DOS, Mac and Windows.

Some of the most known:

* Mario Teaches Typing

* Super Mario Bros. Print World

* Mario is Missing! (also released on SNES)

* Mario's Time Machine (also released on SNES)

* Mario's Early Years! Fun with Letters

There are also (bad) Donkey Kong ports for home computers of the 80s such as Atari 800XL, IBM DOS, VIC-20, Commodore 64.

That looks great, I was not aware this existed.

However, considering you have to build your own custom Arduino board or be on the waiting list to buy one, it's a bit more complicated than "Just buy a simple USB floppy drive for 15 bucks online".

A USB floppy drive won't read Amiga disks.

I'm currently in the process of dumping all my old Amiga floppies too. If your basement was relatively not too humid or hot, the disks should all still be readable.

There are two popular USB floppy drive controllers for archiving Amiga disks: KryoFlux and Greaseweazle. You need a standard disk reader to use along (not a USB one).

The KryoFlux is a bit more expensive but can create complete archival level images (called KryoFlux stream). Otherwise both devices will produce floppy images (ADF) that can be used in any Amiga emulator or written back to floppy to use on a real Amiga.

Here's an overview of the available tools, some of them are pretty old, you can't go wrong with the two I listed above: https://www.amigaforever.com/kb/13-118

Do you mean "it shouldn't be illegal" as in you wish it was not illegal or as in "it is probably not illegal"? Because in most jurisdictions (including the USA) it is illegal to download a backup ROM of something you own. Regarding making a personal backup, some jurisdictions are more permissive but some do not even allow it.

The easiest way is to use a cartridge ROM dumper such as: Retrode, Flash Boy, GBxCart RW, RetroBlaster 2.0, etc.

There are also a lot of DYI devices using Arduino and other popular boards.

Wow, this is the first time I see someone with musical tastes so close to mine. Like you said, a lot of this music feels very personal. So this feels weird now, like meeting a long lost twin. I could have made that playlist.

I was never really able to pinpoint what makes this music good to me. It has to be a mix of the actual sound, texture and repetitive nature of the drone.
