timeinput··on T-Mobile: Are you blocking specific words and suspending accounts?
I ran into this a few months ago when texting the phrase "work from home" it was really strange. We rationalized it with the spam / phishing thought process, but it still seems wrong for the carriers to block messages so poorly.

It makes me wonder if I really want them filtering 'spam' calls.

tinfoil hat maybe that's their end game!

timeinput··on How a Kalman filter works, in pictures
I recommend this article frequently when someone is looking to learn about Kalman filters. It's got some nice I intuition building descriptions. I also like https://github.com/rlabbe/Kalman-and-Bayesian-Filters-in-Pyt...
timeinput··on My thoughts in response to the lawsuit against the Internet Archive
It seems wrong to me to give person hood to corporations. I think letting John Smith do what ever he desires is fine. Letting some entity get legal protection in the form of limited liability should remove a large number of liberties. In other words bullying a company to me is different than bullying a person, but that's some what orthogonal to my other point.

Though I think in this context by bully the OP probably meant something like boycott.

I bought every Cory Doctorow novel through his publisher Tor because he gives them away for free and I enjoyed them. Tor have been acting like bastards to libraries. I now boycott Tor, so I am not buying his books, and I suppose that means I'm bullying the author.

timeinput··on My thoughts in response to the lawsuit against the Internet Archive
I think the root issue is the creator didn't entirely understand what they were giving away. Harper Collins and all publishers don't create content. They are a delivery platform. Unfortunately to use their delivery platform I have to give them exclusive rights to the content (it's even worse than face book and reddit where they merely claim right to use the content).

In return they'll give you <10% of the profits of publishing the book. That seems like a terrible deal today.

On top of that we're also talking about books where the author is dead.

Why is anyone entitled to my creation isn't a valid question to ask of book publishers. They didn't create a thing.

timeinput··on My thoughts in response to the lawsuit against the Internet Archive
I think in a way there is a cultural failing. This feels like a problem some countries don't have. It's not uniquely US, but how big of a problem are large donors in the Netherlands, New Zealand, or Denmark?
timeinput··on Costco Convinces Brands to Cannibalize Themselves
It's been quite a while since I last used the deal since I've not been in the store. I think the last time I used it was something like $80 for $100 in playstation store gift cards, but I think I'm more used to the 10% off as the general rule for their gift cards.

ETA: I just checked online and they're only 10% off (both Xbox and PS).

timeinput··on Costco Convinces Brands to Cannibalize Themselves
Yeah the PS4 and XBox gift cards tend to justify the membership cost on their own for me, so everything else feels like a bonus, and I don't feel bad about wasting money buying something somewhere else even if it's a bit more expensive since the Costco membership is already paid for.
timeinput··on The FBI is secretly using Sabre as a global travel surveillance tool
You assert that they have only arrested people who have destroyed federal buildings? I assert they have arrested people who haven't destroyed a federal building. I assert they've arrested people who haven't violated federal law at all, and that no federal buildings have been destroyed.

Some have almost surely tried to vandalize federal buildings and others who've been arrested have protested peacefully, and still others have only violated state law. None have taken drastic action that would actually destroy a building. I don't care for hyperbole on such serious topics.

All that said I scrolled through your comments. I think at best we won't have a productive conversation on this topic, so I won't invest my time further in it.

timeinput··on The FBI is secretly using Sabre as a global travel surveillance tool
It is of unclear legality whether a federal agent can arrest a someone for violating state law in Oregon. It is more likely that after the mayor and governor have said they don't want this to continue it is not legal.

What is the requirement in your mind and legally to identify as LEO? The feds in Portland allegedly have the word POLICE on their shirts and that's it. Is that sufficient? Would you follow orders from someone in tacticool gear with the word POLICE on it?

timeinput··on Compressed Sensing (2016)
Definitely. JPEG2000 uses a wavelet transform instead of the DCT to achieve similar goals.

One way to think of it is your transforming to some other basis. You could do something similar with any vector base change where you go from a dense representation to a sparse one. Think of things like an eigen decomposition where most of the eigenvalues are small or zero and can be ignored

timeinput··on Compressed Sensing (2016)
I thing DCT is a special case (only real) version of a Fourier transform.
timeinput··on Compressed Sensing (2016)
It was, but the goal isn't lossless recovery it's good enough recovery either in an L1 minimizing sense, or some other criteria
timeinput··on Low-Background Steel
It could be as simple as OP being one of [today's lucky 10,000](https://xkcd.com/1053/).
timeinput··on Receiving images of Earth from satellites with software defined radio
I'm fairly fluent in both DSP and software, and find GNU radio indecipherable.

A plain C/C++ implementation is often so much clearer than a flow graph built in python.

timeinput··on How to Disinfect a Police Car in a Pandemic: Make It an Oven
That's a very clever solution. I've been making it a point to leave my car out side in the sun rather than in the garage for the same reason, though it probably doesn't make much difference given I'm only driving once a week at most.

Does anyone know how accurate the 133 for 15 minute assertion is?

timeinput··on Would you take on a large debt in this economic/political climate?
I considered carefully refinancing my home mortgage recently because of low interest rates. Weighing the closing costs of refinancing I wasn't excited about losing the 4k in liquidity for a net savings of 20k over the next 15 years.

I would consider the impact of defaulting carefully before taking on a new debt today.

timeinput··on What developers should know about TCP
Protobuf isn't self delimiting so you still have to have some extra packet wrapper around it to say the length.

I like zeromq to get to a packet based system.

timeinput··on Kessler Syndrome
Is there any way to watch this without buying DVDs or pirating? I saw it posted a few weeks ago and went looking and came up blank other than purchasing physical media
timeinput··on Kessler Syndrome
Yeah, especially in LEO / MEO. In GEO towards space seems like a better bet though.

Though dead satellites in GEO make a lot more news.

timeinput··on Keep a Changelog
I've found having a line like `CHANGELOG:` in commit messages to make generating / maintaining a change log or release notes type document to be somewhat handy.
timeinput··on Time.gov was upgraded today
You're correct it never has. GPS time started 6 Jan 1980 and has ignored every leap second since.
