What are the upsides and downsides towards refrigerating opened ketchup bottles? I've always kept them in the fridge once they're opened but most people's houses I visit don't bother.

It will probably keep its color and flavor longer in the fridge but it’s unlikely to go bad sitting out on the counter.

There's enough acid, salt and other preservatives in commercial ketchup that it's shelf stable, you can note that it says "for best results, refrigerate after opening" instead of a straight imperative to chill it

I prefer room temp ketchup because it's less viscous, and honestly having worked in a bunch of restaurants, what you should be more worried about is that they often make the wait staff combine a shitton of those open bottles together, so next time you use diner ketchup just know it's probably like six bottles of ketchup knife-dinged into one

For the record, I only use ketchup as an ingredient, I abhor the texture and temperature gap of using it as a condiment or dip, so viscousness doesn't factor into it when I'm making sloppy joe.

Thanks for the info.

I have a small boat/ship question. I'm researching small ships like trimarans or other multihull ships for an ocean-based ttrpg. Sometimes a photo of a trimaran will have netting over the main body to an outrigger (the arms on the side, if I have misunderstood that term). Other small ships will have this, too. What is the point of the netting? What is it used for? Why is it on sometimes and not other times?

Any answers or places to find answers are greatly appreciated.

It's mostly just a safety measure. In a smaller cata/trimaran in strong winds, it's not at all uncommon for one of the outriggers to be lifted up out of the water, rolling the entire ship. In that case you may want people to go and sit on the outrigger to act as a counterweight (as the ship will usually go faster the more upright it remains), so there's a risk for people to lose their footing and fall into the space between the main hull and outrigger. In more sporty ships people will usually be harnessed directly to a line to prevent that from happening, so that may be one reason why you might not see them.

Apart from that, if you're doing more of a pleasure cruise kinda thing, they're basically a comfy hammock to chill in when you're at anchor.

I bought a pack of them from a local Chinese grocery. They're quite tasty. They absolutely stink, though - I guess they're probably fermented? There's a chain of restaurant near me that usually has the same smell coming out of it, so I'm really curious what it actually is.

Funnily enough they have a really nice aftertaste. I think I enjoy the aftertaste more than the taste when eating them. I don't know any other food I've had that's like that...

Easiest thing is to open one at the same bank, but you can probably find higher interest rates elsewhere. Look for "high interest savings," seems like 3% is the rate to beat atm but that's just from a cursory look. A lot of them offer high % yield on the first 5k or something like that, less yield on the rest. Some people even game this by opening such accounts at multiple banks with similar deals.

Maybe also post in the BFC newbies thread where they probably have more up to date info.

They are different algorithms for compressing and storing sound.

An analogy would be compression formats like .zip and .rar but instead of being separate files, a video file can have the audio stored within the file in different formats. Similarly the video portion of the file can be stored in different codecs like H.264 or MPEG-4.

So the software playing the file will need to have support for both the video and audio codecs used in the file.

That said, I have not needed to deal with individual file formats or codec issues in years thanks to programs like VLC that pretty much always play any file out of the box.

Your life and your quest end here.


Probably no one knows the answer to this, but it's a mystery that's got a firm hold on my brain so I've got to ask in case anyone has a better guess than I do.

Every YouTube channel has an RSS feed. The URL will be something like https://www.youtube.com/feeds/videos.xml?channel_id=UCJpPXZwyo0fgu3h94R3P5pA

They used to have a relartively prominent link to the feed URL and a FAQ about how to subscribe. They haven't had either of those for a while, but the metadata was embedded (so a browser with built-in RSS capabilities could add a button to subscribe to the interface), and if you knew to look for it you could still find the channel ID to subscribe manually. But it seemed like they didn't want people to use it.

They've recently changed the way channel pages work, and that RSS metadata is gone, and the channel ID is even harder (but not impossible) to find.

It really seems like they don't want anyone using RSS.

So why are they still allowing it? If they don't want anyone using it, why not turn it off? If they wanted people to use it they wouldn't keep burying it further and further underground where no one can see it. But if they don't want people to use it, what's it for? Why is it still there?

The most plausible possibility I could come up with is that they've forgotten it exists. No one's supporting it, but no one's gotten rid of it, because no one knows it's there. But that seems unlikely. It's not exactly a secret. You can easily find various guides on accessing it. People know about this feature. But what other explanation could there be for making it as inconvenient as possible to use but not just killing it outright?

BonHair
Apr 28, 2007

From software development, my experience is that it's probably a feature almost no one uses, so they want to spend as little resources on it as possible. This means hiding it so no one will begin using it, but also not getting rid of it, because properly removing it also takes time. Also the two guys (that's you) who uses it would complain.

At some point, other changes will break the RSS feed functionality and maybe then it will be removed, or more likely just be left at vestigial broken code.

On the other hand it could be that someone did notice this got used 'too much' to avoid all the user hostile garbage on the website and they're making it more difficult to access so that later on they'll have the metrics to prove that indeed nobody is using it and they're justified in scrapping it.

As for why there's so many: decoding audio is a valuable thing for a computer to do, but it also poses a number of challenges around audio fidelity, disk space utilization, and CPU utilization. It's only been in the last 20 years or so that we could take it as given that any computer would be able to provide high-quality sound output without struggling. Prior to that point there were a ton of different codecs that optimized for different things. For example:

- .wav optimizes for low CPU utilization and high fidelity, but as a consequence uses a ton of storage space.
- MIDI optimizes for low storage space and CPU utilization, but does so by basically being sheet music for a set of "instruments", which means that a) it can't do arbitrary sounds, and b) if you don't have the right instruments installed then it won't sound right on your machine.
- .mp3 and .ogg both have adjustable bitrates, meaning that they can trade off disk utilization and fidelity depending on your needs. But they have fairly high CPU loads.

A few other newer formats exist mostly for bad reasons. Apple invented some new codecs so that it could use DRM to make sure you could only play them if you'd bought the songs off of the iTunes music store. .ogg exists in the first place because .mp3 had some patent restrictions or something on it, that meant that software developers that wanted to include MP3 decoders in their code had to pay a license fee.

and then there's flac, which i is uncompressed, and therefore lossless. i'm not really sure what differentiates it from wav, as i'm pretty sure it's lossless too? and if it's the purest digitization an audio sample can get, theoretically, wouldn't they be identical?

Flac is losslessly compressed. Lossy compression (eg mp3) actually ditches data that is considered inaudible. Flac can be reconstructed to the original audio, bit accurate. It's like wav, but takes less space.

E: Flac is like putting a pillow in a vacuum storage bag. Mp3 is like saying 'no one will notice if we remove some handfuls of feathers as well to make this even more compact'. Wav is just the pillow.

I think it's a stretch to call midi an "audio codec." It really is sheet music for a soundcard's midi driver. It does not encode actual audio signals.

I mentioned it because it's an example of one of the ways people approached sound design on earlier computers. It's not a codec, no, but it showed up in the same spaces that codecs did. MIDI got used for a lot of stuff, and for a long time was the only realistic way to share songs online.

What is an audio codec, why are there so many, and why do I never have the correct one?

The other posters gave pretty good advice about the difference between audio formats, but didn't quite go into what a codec is:
Codec stands for "encoder/decoder", and it's the piece of software that's specifically in charge of translating raw soundwave data into the compressed form of a format like mp3, flac, opus, etc. (Codecs exist for video formats too.)

When your music player, browser, etc encounters an mp3 file, it doesn't interpret the file itself. It has to call out to the specific "mp3 codec" somewhere on your system, which will transform that compressed file back into a raw waveform format that the program can do something with or your speakers understand.

Some formats use patented techniques, including the h.265 video codec (which is one of a few different ones that can be used for an .mp4 video) and in the past the mp3 audio codec (although it expired in the US in 2017). That means nobody can write their own codec software without the permission of the owners, meaning basically you gotta pay them to use them. So if I am a software developer making a video player, I cannot distribute the h.265 codec with my player, and my player will be unable to read those videos unless somebody else puts it there.

Microsoft now pays money to the h.265 people to include their codec with Windows, but in earlier versions they didn't and you wouldn't have been able to play those videos without downloading the codec externally or paying for it. That's also why Google created the webm format -- the main competing video formats were all patented formats, and they wanted a "one true format" that would be portable and usable anywhere without having to pay for a license. Mostly because of Chrome and Youtube.
So they made their own vp8 format and codec, free with a permanent royalty-free license so anyone can use it.

To follow on from this, flac is compressed in the same was a zip file is compressed. You can unzip a zip file and get all your data back exactly the same as it was before it was compressed. You can't do that with mp3 or ogg, which are lossy compression.
