> TCP tuning

I think a lot of file transfer issues that occur outside of the corporate intranet world involve hardware that you don't fully control on (at least) one hand. In science, for example, transferring huge amounts of data over long distances is pretty common, and I've had to do this on boxes that had poor TCP buffer configurations. Being able to multiplex your streams in situations like this is invaluable and I'd love to see more open source software that does this effectively, especially if it can punch through a firewall.


It is relevant, though. I have 1.2 Gbps down with a 2 TB monthly cap. I've never hit the monthly cap even once, but by your standard I have "1.2 Gbps down for 3 hours, 42 minutes".

But that doesn't change the reality that it matters to me that a 20 GB video that a friend took at my wedding downloads in just 2 minutes rather than the ~30 minutes it would take if I had a 100 Mbps connection.


Right, but 3+ hours of top speed per month is a lot, 80 seconds isn't.

Your cap is over 150 times that equivalent. If you had an 80 second hard cap, you couldn't even download that 20GB video.


1.2Gbps down but only 2TB cap? I hope that's really cheap since if I pay for that I'd expect to do stuff like downloading LLMs, etc, all the time.


I do think it's vastly superior to preferential treatment for some traffic, which seems to be the most popular alternative. The one caveat is that ISPs need to be forced to be transparent about this. Often, with cell providers, it's "Unlimited 5G" advertised, with a tiny asterisk pointing to even tinier disclaimer text at the bottom explaining that they throttle your rates once you hit a (fairly low) cutoff. That type of misleading marketing undercuts the fairness of the offer.


I believe they are saying they literally edit the media files to add / change metadata. Cross-seeding is only possible if the files are kept the same.


QSH?


At least that isn’t an existing ham radio Q-code!


I thought the same, but no doubt pawn promotion rules dramatically increase the depth needed to reach certain positions.


I endorse the view that everyone should use an ad blocker, but for what it's worth I keep seeing this techcrunch article and the original advice offered by the FBI [1] is actually much more limited.

> Use an ad blocking extension when performing internet searches. Most internet browsers allow a user to add extensions, including extensions that block advertisements. These ad blockers can be turned on and off within a browser to permit advertisements on certain websites while blocking advertisements on others.

So the specific recommendation is that you turn on an ad blocker while performing searches. Why are they so concerned about searches? It's because of a specific form of fraud, where someone purchases an ad pretending to be the business you're searching for, but actually takes you "to a webpage that looks identical to the impersonated business’s official webpage" - that is, a phishing scam.

That's way more limited than the "FBI recommends ad blocker" statement would lead you to believe. From the FBI's point of view, pitching a bullshit supplement in an ad (what you're talking about) is an entirely legitimate business practice, and selling supplements is legal in the US so long as you don't make certain medical claims or imply FDA approval.

I borrowed the phone of someone who is older to watch a facebook video in the app. In the middle of the video there was a video ad with sound playing, an amber alert for sound and a warning to click the link. The next ad after that one was also a warning that there was a virus and you needed to click the link


In the age of A.I. blocking that kind of content should be easier than shooting fish in a bucket and the false positives should all be things the platform would be better off without.


I think searches are just a common entry point to the internet at large. People search then they have some mistaken trust those links are legit.


The promise is especially dangerous when a huge fraction of traffic doesn't use Encrypted Client Hello, [1] so the domain name is sent in the clear with the initial request to the server.

A while back I wrote a quick proof-of-concept that parses packet data from sniffglue [2] and ran it on my very low powered router to log all source IP address + hostname headers. It didn't even use a measurable amount of CPU, and I didn't bother to implement it efficiently, either.

I think it's safe to assume that anyone in a position to MITM you, including your ISP, could easily be logging this traffic if they want to.

IMO the denoising looks rather unnatural and emphasizes the remaining artifacts, especially color fringe around details. Personally I'd leave that turned off. Also, with respect to the demosaic step, I wonder if it's possible to implement a version of RCD [1] for improved resolution without the artifacts that seem to result from the current process.

Yeah I actually have it disabled by default since it makes the horizontal stripes more obvious and it's also extremely slow. Also, I found that my vertical stripe correction doesn't work in all cases and sometimes introduces more stripes. Lots more work to do.

As for RCD demosaicing, that's my next step. The color fringing is due to the naive linear interpolation for the red and blue channels. But, with the RCD strategy, if we consider that the green channel has full coverage of the image, we could use it as a guide to make interpolation better.


When you do the demosaicing, and perhaps other steps, did you ever consider declaring the x-positions, spline parameters, ... as latent variables to estimate?

Consider a color histogram, then the logo (showing color oscillations) would have a wider spread and lower peaked histogram versus a correctly mapped (just the few colors plus or minus some noise) which would show a very thin but strong peak in colorspace. A a high-variance color occupation has higher entropy compared to a low-variance strongly centered peak (or multipeak) distribution.

So it seems colorspace entropy could be a strong term in a loss function for optimization (using RMAD).


Do you share some of the original raw recordings somewhere?


Yeah, i dont think the denoised result looks that good either


Best phone I've ever owned and it's not close. Every phone since then has been a compromise, to the point that (in a sunk cost fallacy kind of way) I've just quit caring about phones and just buy whatever the cheapest available unlocked device is. I run them into the ground (way past the end-of-service date) because I know the next one is going to be worse.


The Nexus 4 was a nice phone but I thought the battery life was bad and it also ran hot.

My Moto-X was truly next level. It was oled and could do always on display that didn't need to power the blacks pixels on the screen. It was the first phone to do this. It has voice recognition for unlocking (getting info that you couldn't when the phone was locked). First to do this too since I believe it uses dedicated hardware at the time. It also knew when I was driving to unlock the phone for voice commands also. It was small.


Nice throwback. The Moto X was awesome. Damn, phones were so exciting back then.
