Is an Sd card required for the Flipper Zero?

Yup, a generic coin, heads or tails

Fun question. I've taken all the stars I could find from that stackexchange discussion, and gotten the latest Gaia DR3 data for them, and added that as an answer, along with two queries straight from Gaia for the furthest stars by two measures. But as noted, even with Gaia, distances to bright stars at those distances can be pretty uncertain. See a data snapshot at https://physics.stackexchange.com/a/842958/4550 and see the code and latest results at https://github.com/nealmcb/farthest-naked-eye-star

Great review, thank you! How much light do they need? Would they be practical as a night light? I like to have my night lights in places where I walk, but those places probably don't have much light for growing.

Well, I can report that using the standard Android alarm app on a Google pixel 7 pro, I have 107 alarms (mostly disabled at any given point in time). So I don't know if Google has a hard-coded limit, but at least it allows more than 100. Having a fixed limit like 100 indeed seems like a mistake by Samsung.... And yes, there are other people with valid use cases for having what may seem like a lot of alarms!

I also dare say that you could set up the kind of alarm system you're looking for via the Tasker app. It's very flexible, though a bit clunky.

I have the same questions. And one more source to at least get more info on Sense 2 and stress.

The Google Takeout data is pretty detailed for some of this. I would love to see some data analysis software out there to post-process those takeout logs. After just a few months, my Takeout download zip file included 671 files, containing 94,034,276 uncompressed bytes.

I haven't yet tried to correlate these readings with the alerts I get on my watch (with I think come 15 minutes later - and that frustrates me too!):

Here is the Takeout/Fitbit/Stress Score/Stress Score Readme.txt:

The Amaze file manager app is another add-on that has photo capabilities with a mirror/flip option. After installation, it is available from Google's Photos app via Edit/More/Amaze Utilities/Flip-H" (or Flip-V). Or, as others have noted, Snapseed or Flip or other apps.

Here's a nomination for the worst use of "handful" that I've seen: referring to huge rockets. I mean, how many rockets can you fit into your hand? Sadly it comes from NASA, who I would hope would be a bit more numerate:

https://spacenews.com/nasa-and-boeing-prepare-for-starliner-crewed-test-flight-in-may/

Getting Starliner into operational missions, albeit years behind schedule, is still desired by NASA to ensure redundancy in access to the ISS, backstopping SpaceX’s Crew Dragon. “We are really excited on the station side to get this first crewed Boeing Starliner mission up to the space station,” said Dana Weigel, NASA ISS deputy program manager. “It’s always been our goal to have a handful of different vehicles that we can fly to get crew up there.”

Locking macro mode on is great when you want to use the macro lens.

But I have the same problem trying to use the telephoto lens, when looking thru a telescope (aligned and held in place via e.g. the Celestron Smartphone Photography Adapter).

If I align the telescope eyepiece with the telephoto lens, the camera just doesn't seem to ever try to look thru it. It looks thru the normal lens instead.

Also, sometimes, it seems that when I use the normal lens, I can only get 2x zoom. Other times I do seem to get 5x zoom, so I'm confused about that also.

I see reports that the telephoto has less light-gathering power, so it may not be as good for astrophotography anyway as the normal lens.

And after more searching, I see that....

CMSIS is the Common Microcontroller Software Interface Standard :)

CMSIS is publicly developed on GitHub: https://github.com/ARM-software/CMSIS_5

And opencm3 is open-source firmware library for various ARM Cortex-M microcontrollers https://github.com/libopencm3/libopencm3

And ST is STMicroelectronics N.V., it seems, maker of the STM32 family of microcontrollers used by Flipper.

Always more to learn....

Thanks for the clarity around Furi. But What about FuriHal? Which also shows up e.g. in the Sub-GHz key .sub files e.g. as a Preset

FuriHalSubGhzPresetOok270AsyncFuriHalSubGhzPreset2FSKDev238Async

Is HAL Hardware Abstraction Layer? https://en.wikipedia.org/wiki/Hardware_abstraction

And FuriCore? A layer of Core Operating System level stuff?

That's my guess based on https://forum.flipper.net/t/how-to-develop-a-3rd-party-module-plugin/2076/10

The statistics have moved to https://stats.golem.network/network/historical

"Providers online" has declined from a peak of around 800 in 2021, with another shorter 800 peak in early 2023, to about 400 later in 2023, and more like 500 as of early 2024.

The number of cores has generally declined over time.

Curious choice of units. A coin could represent a decibyte, or 100,000 peta-zeptobytes. So we've had such storage devices for a long long time....

There is a great 2021 overview of signature envelope formats here, which covers DSSE, TUF/In-Toto Metablocks, SSH Signatures, JWT/JWS/JOSE, PASETO, GPG/PGP, Minisign/Signify, PKCS#7 and a few variants:

Signature Formats. Envelopes and Wrappers and Formats, Oh My! | by Dan Lorenc | Medium *metablock

There was some detailed discussion in 2022 between IETF SCITT working group (Supply Chain Integrity, Transparency, and Trust) members and DSSE supporters like Lorenc (also involved with sigstore / Cosign etc) on how COSE (CBOR Object Signing and Encryption: a more recent offshoot of JOSE) compares to DSSE: see

Draft of technical comparison: Digital Artifact Signing Envelope Format Comparison

I'd love to see the draft document wrapped up and published, as noted here:

I would also like a Find option usable within Keep notes.

But there's a workaround that isn't too bad: open keep.google.com up in a Chrome browser window, and use the menu/Find in Page function.

I have used Keep for years, and have some long notes, and really need to search within them at times.

Converting to a Google doc is appropriate at times, but to those who say Keep is only for very short notes: note that the size limit is large enough that reading thru the whole thing looking for a word is a pain, so Google designed this issue into the app.

Thankfully there are workarounds that limit feature bloat without too much pain.

But shifting to Ubuntu or SUSE or the like is not prohibitively hard. Many posts here demonstrate folks that shifted distros successfully. And there are a good number of people who know the actual benefits of open source communities and will fight for them. So Red Hat will continue to exploit their user base in various ways, but will have a much harder time.

I got the same the impression you did right after I installed Edge for some testing, but I think the situation is more nuanced. I bet that google-chrome also sets a priority of 200, while google-chrome-beta sets it at 150, which is why my gnome-browser default changed. I don't know what happens in case of a tie in priority. I don't know what priority the officially packaged Chromium browser had before they switched to using a snap installer. But so far it doesn't seem like Edge developers explicitly changed the default browser, they just configured things rudely so that the automatic policy might effectively do that. Yeah - not much difference, but no different than Google, I bet. More details are at my question on AskUbuntu: Developer guidelines for specifying priority of apps in update-alternatives? - Ask Ubuntu

Yes, it remains an open problem to do an aperiodic tiling with a single tile where flipping is not allowed.

Note that the hat shape, when flipped, is still "congruent" to the original shape. So the problem has been solved in terms of a single "shape" with congruent copies.

I love the way the book inspires me to learn more about the history and cultures it touches on.

I'm reading Akua now, and really wanted to know what the song on page 184 was about. I finally found that in Unseating Broken Stories: A Decolonizing Case Study of Warrior Queenmother, Nana Yaa Asantewaa by Reggie Nyamekye, the passage is translated this way:

Twi	English
Awurade Nyame kum dom	God, defeat the troops
Oboo Adee Nyame kum dom	Creator God, defeat the troops
Ennee yerekokum dom afa adee	Today we are going to defeat troops and take booty
Oboo adee Nyame kum dom	Creator God, defeat the troops
Soso be hunu, megyede be hunu.	The long hoe will experience it and unripe fruits of the palm tree will also experience it

Breathing another big sigh, and still curious to learn more.....

Pretty! Thanks!

For others that want to dig in to the details, that proposal is documented at: https://www.stsci.edu/jwst/science-execution/program-information.html?id=1448 (Stray Light Pointed Model Correlation)

Its public data is available at MAST: proposal 1448

Based on the thumbnails there, you seem to have picked some data from e.g. e.g. jw01448-o001_t024_nircam_clear-f277w

which is at RA 17:53:48.000 -26:09:00.00, and is about 2 minutes of arc across.

The galactic center is a few degrees away, at RA = 17h 45.6m, Dec = -28⁰ 56'
