That would mean that higher sampling rates (which add more inaudible frequencies) could cause similar problems. OK xiphmont actually mentions that, sorry, I had only watched the video when I replied.

Someone else wrote that it was chosen to best match PAL and NTSC. IIRC there is also a Technology Connections video about those early PCM adaptor devices that would record to VHS tape. < https://en.wikipedia.org/w/ind

> Now you could play it back wrong by emitting a sharp pulse f_s times per second with the indicated level. This will have a lot of frequency content above 20kHz and, in fact, above f_s/2. It will sounds all kinds of nasty. Wouldn’t

This is a nice video. But I’m wondering: do we even need to get back the original signal from the samples? The zero-order hold output actually contains the same audible frequencies doesn’t it? If we only want to listen to it, the stepped wa

I’m wondering, wouldn’t a default deny inbound firewall still need hole punching with IPv6? You wouldn’t need STUN to find your global address but if you use varying ports you’d need to communicate the port first, and you’d also need to tim

You should use unique local addresses (ULAs, fc00::/7) not link-local addresses (fe80::/10) for this. Choose a random prefix and advertise it in your network (you can use some website like https://www.unique-local-ipv6.

There’s a difference between the European version of the Apple dongle and other regions. The European version maxes out at 0.5 Vrms instead of 1 Vrms.

Usage at call site: using (var result = foo.GetSomethingIfLucky()) { if (result.IfHappy is {} success) { // do something } }

You have to write a disposable wrapper to return. Return it in error case too. readonly record struct Result<TResult, TDisposable>(TResult? IfHappy, TDisposable? Disposable): IDisposable where TDisposable : IDisposable {

by brewmarche 9mo ago
You can move the burden of disposing to the caller (return the disposable object and let the caller put it in a using statement). In addition, if the caller itself is a long-lived object it can remember the object and implement dispose itse

In C# the closest analogue to a C++ destructor would probably be a `using` block. You’d have to remember to write `using` in front of it, but there are static analysers for this. It gets translated to a `try`–`finally` block under the hood,

I agree, although I am a bit surprised to see that we’ve used more than half of the protocol numbers already

What if extension headers made it better? We could come up with a protocol consisting solely of a larger Next Header field and chain this pseudo header with the actual payload whenever the protocol number is > 255. The same idea could al

Apologies, my post was not precise enough, but I think I got it. > It wouldn't be practical to make it behave quite like an L2 switch. What are typical configuration? If you’re allowed to talk about it.

So, if I know the destination addresses on each port in advance I can program it to behave like an L2 switch (with proper multicast even), and I can use code to reprogram it whenever the traffic pattern changes?

Interesting that they went with a custom MIME type and a custom version header. I would have expected the version to be in the MIME type, but I feel like there is a reason behind this.

Are L1 switches like hubs or repeaters then? Sorry for my confusion.

Maybe surprising for days (could also happen with minutes because of leap seconds technically :-) but for months and years this is more apparent due to month ends and leap years.

I don’t think it’s a metric for 0 < p < 1 though.
