Thanks. Now I finally get it, but am still no less annoyed that this doesn't "just work."

Thanks for posting that! I've always wondered what the deal is. How do other file systems do it differently that allows for concurrent access to the file?

I think most of the apps use WAL nowadays (at least from what I remember when I looked into this a while back) but I'll have to check again! Thanks.

It does work... Sort of. From what I've read, the NFSv4 server properly implements locking (and I think most of those bits are in the Linux kernel now anyway), but sqlite won't support it anyway. And I am able to run sqlite on NFS

by kayson 3y ago
I've had the same experience. I have a NAS VM with nfs4 on Debian, but my services are running on other VMs (since they're in a DMZ vlan). A lot of selfhosted stuff runs on sqlite since its just easier. So there is only one user p

by kayson 3y ago
A real exciting improvement would be support for NFS, instead of hiding behind "some server implementations don't implement locking properly" in 2023...

Did I miss something in the article? They see the connections were made, it was plain http, but they didn't actually show any of the real payload/data? Instead they quoted the list of what Qualcomms policy says could be collected?

Linear regulators also have a start-up time, and its usually somewhere in the datasheet. All feedback loops have some kind of settling response time depending on the bandwidth of the loop, and you'll see that behavior both on start-up

Theoretically, yes, but in practice, no. Creating a manufacturing process is a very complex and time consuming process that takes a huge about of research and development, investment, etc to achieve profitable yields. For bulk CMOS processe

No that's definitely not the case. For digital design, in general, you're not doing anything transistor-level. But those digital designers are using standard cell or memory libraries which are created at a transistor level. I beli

Sorry my comment wasn't very clear about this. There's still secret sauce in the materials. The GDS is purely dimensional. It's just a bunch of shapes. But how those shapes get translated into actual silicon, and how various

Why is cloudflare vomit-inducing?

My point is that practically speaking, it does matter where the signal is, depending on how you filter it. If you lowpass filter an RF- (or, more realistically, IF-) centered signal, you can't just sample it at 2X bandwidth because y

Looks like I bundled that second inequality. Band pass is X(w) = 0 for abs(w) < A or abs(w) > B
257.
by kayson 3y ago
I'm afraid I'm not mistaken (source: I design integrated RF transceivers) ;) Yes, you can subsample if you have a suitably bandpass -limited signal. But that's not the general case, nor is it what the nyquist-shannon theorem
258.
by kayson 3y ago
I can see why you might think that but consider that in RF systems, while the wanted signal is bandlimited, you also have a lot of unwanted "blockers" all over the spectrum that need to be dealt with before sampling.
259.
by kayson 3y ago
To clarify: "band-limited" usually means X(w) = 0 for abs(w) > B for some B, where X is the frequency spectrum. And that's the definition Shannon used in the original proof, which is where the idea of Nyquist Frequency com
260.
by kayson 3y ago
Yes, but this only works if, as the page points out, the signal is bandpass filtered, which GP did not mention. It's not true in the general sense, nor is it practical for many (most?) RF systems, especially those with multiple channel
261.
by kayson 3y ago
I know what you're getting at, but your statement, as others have pointed out, is incorrect. Your sampling rate always always has to be twice the highest frequency of the signal you are sampling. If you are sampling an RF-modulated sig

I've looked at syncthing and the usage model isn't quite what I want. I really want a dropbox alternative, for my users' sake, as opposed to a decentralized synchronization service.

Encryption on Nextcloud is a mess. Something about their update process is enormously fragile and its often pain to do (side note: I recently discovered there's a CLI updater, and that's definitely the way to go). I eventually jus

How is this not completely I/O bound? What's so cpu intensive that programming language matters?

The main reason I still use Make over other alternatives is that everyone already has it. No need to install something else to bootstrap a project. I put in a `make initialize` that takes care of everything: setting up the virtualenv, using

There are bajillions of mosfets; you can certainly find another one that works even if it's a tiny bit more expensive.
