Hi, original presenter here :) The beginning is FTs 101. The end gets more application-centric around OFDM and is why it feels 'unreasonably effective' to me. If it feels obvious, there's a couple of slides at the end that

As someone else posted a link to the Reddit thread, I posted there to say, roughly, 'no, I'm pretty unhappy about it'.

Lance -- I really like this comment because it is a compelling argument for something other than the viewpoint I hold. Obviously I am not fully convinced by it (yet?). But this is the kind of discussion that we had hoped for in response t

I was Chris's housemate at the time, the victim of the hours of 'sssshhhh sssshhhh shhhhh'. Interestingly, he rendered this mostly by drawing boxes in pov-ray -- I'm not sure what he used to make dimensioned drawings, b

Oh, and a quick update on this -- I just got mail back from Chip at Wahoo. (Looks like my previous mail got caught in a spam filter.) They're looking to get a bunch of the attribution and source issues cleaned up shortly. I'll

I was kind of surprised too. I have some conjectures about the internal politics from the output that I observed (super friendly, super helpful support team; development team knew it was an issue, and had orders from above?). And yes, the

Hi, HN! Author, here. Yeah, I was a little disappointed by the GPL and attribution issues, too. But also, I feel a little bad not having given them too much time to respond, or too much heads up that I was gonna write a piece about it.

Well, what you want and the physical realities of synthesis are different :-) In the early days of compilers, of course, you were mostly writing C as a macro language for your system's assembly language. If you wanted your program to

I think I agree with at least some of what you say. I feel bad viewing content from small blogs without "paying" for it. My current best compromise is that I run uBlock Origin with an exemption for Google, and then I use Contrib

Well, the royal "we", perhaps :-) I started blocking ads because they dramatically slowed down my browsing experience. But I keep blocking ads because, fundamentally, I believe that advertisements are neurotoxins, and nobody has t

I've served a whole bunch of roles in my five years at my current employer, and I'd probably classify myself as being an "electrical engineer" for all of them. (No single experience is typical, but mine is probably repr

I applaud the idea of helping people with depression, anxiety, mood disorders, and that cluster of symptoms and illnesses. We talk a lot about how it's prevalent, but we don't talk a lot about what to do about it. That said, I do

It seems that this is getting downvoted, and I want to explain why I agree with the downvotes: The policy on that web page has two egregious issues. 1) It does not have any provisions for SPAM. I regularly get e-mail SPAM that has CloudFla

Interesting. I've seen some other work done on gradient-aware demosaic using directional masks, and the devil appears to be in the details: it can reconstruct a lot of sharpness when images are aligned with masks, but it also tends to

Also, is it just me, or does the logo look like it says "fu"? I bounced it off a few other people and they also all seem to think it says "fu". (I was looking at https://www.amium.com/img/features&#

I think there is a fair bit of "how to lie with graphs" here going on. For instance, the 'housing construction boom' very carefully does not show any context before 2014, and although it rockets up from the bottom left

I think I'd take the opposite tack, by the way. I get about a zillion job recruiter e-mails, and the vast majority are mail merge. It's irritating, but not disqualifying, for the recruiter. If we put up with it that direction, w

On the one hand, I'm happy to see visionaries like Vi Hart and Bret Victor (and presumably the others who I don't know of their work, but can only imagine to be quite good) supported to do the work that they do. On the other hand,

Well, you can call me that, but that's not my name :-) I'll not delete my comment. I'm worried, really, about two categories of abuse: 1) Abusers who are not persistent, but who create multiple accounts rapidly (i.e., aiming

I talked to a friend who was considering building this kind of startup recently. The two 'hard questions' that I found were: 1) How do you plan to deal with abuse? Connecting anonymous Internet users to people who are at their m
