My LG does just that.

The tv remote sensor stopped working (and broke again after servicing), so now the only way to use the TV is by the LG app on my phone.. which asks for permissions to Nearby Devices, Location, Camera, Microphone, Notifications, Phone, Music&Audio...


Lots of good generic remotes out there (still using a Logitech harmony personally)


This remembers me of the Modbook, back in... check notes... 2008? I'm old. They would take a Macbook, re-case it and transform it into a tablet. Super cool. Looks like they kept doing this for a few iterations.

Not sure if it adds anything, but a factoid I know is that CD timing is expressed in minutes, seconds, and frames, where each frame is 1/75th of a second.

I'm not sure but I think this is also the smallest time resolution.

Then each frame is composed of samples, but they seem to be counted in groups of 1/75th os a second anyway.


That's only relevant for navigation from the TOC. The samples are always 22.68us apart. That is the finest resolvable timing difference.


I was also wondering about the inherent resolution for the BPM precision claims.

Besides the sample period, the total number of samples matter for frequency resolution (aka BPM precision).

44100 Hz sampling frequency (22.675737 us period) for 216.276 s is 9537772 samples (rounding to nearest integer). This gives frequency samples with a bandsize of 0.0046237213 Hz which is 0.27742328 BPM.

Any claim of a BPM more precise than about 0.3 BPM is "creative interpretation".

And this is a minimum precision. Peaks in real-world spectra have width which further reduces the precision of their location.

Edit to add:

This takes my flac rip of the CD and simply uses the full song waveform. This artificially increases frequency precision by a little compared to taking only the time span where beats are occurring.


This is plainly false though. You're saying beats can't be localized to less than one second of precision (regardless of track length, which already smells suspect). Humans can localize a beat to within 50ms.


Yes, I got lost in the numbers and made a blunder by misinterpreting what we mean by frequency resolution expressed in "BPM" instead of Hz.

It is correct to say "0.0046237213 Hz which is 0.27742328 BPM". My mistake was to interpret 0.27742328 BPM as the limit of frequency resolution in units of BPM. Rather, any BPM measured must be an exact multiple of 0.27742328 BPM.

Thanks for pointing out my mistake!

> (regardless of track length, which already smells suspect)

Frequency resolution being dependent on the number of samples is a very well known property of basic sampling theory and signal analysis.

In fact, one can interpolate the frequency spectrum by zero-padding the time samples. This increases the resolution in an artificial way because it is after all an interpolation. However, a longer song has more natural frequency resolution than a shorter song.

Note, this frequency resolution is not related to fidelity which is some messy human related thing that is over a sliding window of shorter duration that I don't pretend to understand.

BTW, the opposite is also possible. You can zero-pad the spectrum as a means of resampling (interpolating) the time domain. This is slower but more spectrally correct than say time-domain linear or cubic interpolation.

These techniques require an FFT and so are somewhat expensive to apply to long signals like an entire song, as I did for the plot. Daft Punk's HBFS takes about 8 seconds on one CPU core with Numpy's FFT.


for me 16gig is definitely not enough.

I'm on a 36gb M3 and I have to reboot it every three to five days to have it behave again.

I have normal dev apps open: a browser with jira, another with testing, another with documentation, an ide, teams, calendar, zoom.. it adds up very, very quickly. 16gigs are gone in the blink of an eye


If you have to reboot to get it useable again instead of just killing and re-launching the applications there's something wrong with the OS, not with the applications. Have you tried killing and re-launching the browsers and pseudo-browsers (Teams etc.)?


adults passengers can adapt the conversation to your needs, keeping quiet and even helping with decisions. screens, kids, dogs, people on the phone, etc can't do that


It's very hard to have ChatGPT et al tell me that an idea I had isn't good.

I have to tailor my prompts to curb the bias, adding a strong sense of doubt on my every idea, to see if the thing stops being so condescending.


Maybe "idea evaluation" is just a bad use case for LLMs?


Most times the idea is implied. I'm trying to solve a problem with some tools, and there are better tools or even better approaches.

ChatGPT (and copilot and gemini) instead all tell me "Love the intent here — this will definitely help. Let's flesh out your implementation"...


Qualitative judgment in general is probably not a great thing to request from LLMs. They don't really have a concept of "better" or "worse" or the means to evaluate alternate solutions to a problem.


Even worse: If you have any complaints, call a number we won't publish anywhere on our site and a robotic voice will just laugh at you.


My YT mobile pet peeve is that when you toggle the captions, an useless "Subtitles/CC Turned ON" is shown for 5 seconds.. OVER THE CAPTIONS!

Most useless message ever, placed exactly where you do not want it to be.


I can never tell if the toggle is CC on or off until I wait and see captions or realize nobody has talked yet.


YouTube is now full screen.


Bolsonaro termed "far right" seems to be on the mark though. The guy praises military dictatorship, with many military figures in his government. He targeted the press and judiciary as enemies of the nation, and so on.

Lula hasn't nationalized industries, hasn't seized wealth, or even tried to, so "far left" doesn't seem to be as fitting. Where are the burnt churches?

Now, about corruption, I'm pretty sure neither shine, but that's Brazil for you. Wasn't the Bolsonaro family found to have bought around 50 properties in cash? Smells about as corrupt as the other side, sadly.


> And they are incapable of putting tariffs on online services and digital products.

This would be interesting. And worrying. Laws are easy to write, regardless of applicability.


I guess the politicians don't want their Netflix to be more expensive.

Sadly its the EU and for every law there are untold numbers of lethargic and mostly incompetent beaurocrats trying to enforce it.

Those work very every slowly, but they are many and usually unstoppable when it comes to collecting money.


The thing about tariff wars is that you never want to shoot your full quiver in the first encounter, but keep some arrows for the next one. And the one after that.

I wouldn’t be so disappointed just yet; even the most lethargic beaurocrats in the EU know what’s going on. This ship is slow to steer, but if she gets moving, she’s hard to stop. Just wait!
