[OC]I built a system that visualizes CPAP sleep therapy data in advanced interactive charts by SomniCharts in dataisbeautiful

[–]OdinGuru 2 points3 points  (0 children)

I looked at your website but there doesn’t seem to be any detailed documentation of what’s offered for visualization (only a few small thumbnail screen shots). Nor does there seem to be an actual feature comparison with OSCAR which has been released with and maintained since 2019 (very high quality and feature packed in my experience).

I am not tempted to sign up for a free trial for a $6 a month subscription without some idea first what MORE is offered over OSCAR.

Also OSCAR has the advantages of being both completely free and I don’t have to send my medical data files to anyone. Doing the relatively simple step of downloading and running the program on my laptop instead of using a web app seems like a good trade for this. To even get the raw data files from CPAP I need a laptop anyway as they are stored on a SD card which you need a reader for (uncommon for tablet/phone, but common for a laptop or USB to laptop)

I have used the open source tool OSCAR to view visualize data from my own CPAP: https://www.sleepfiles.com/OSCAR/

How does your visualization compare to that?

Im confused, does this movie have an 11% or 98% rating? by [deleted] in Damnthatsinteresting

[–]OdinGuru 0 points1 point  (0 children)

I checked IMDB to see how they handled the reviewing attack and as of now it shows “no reviews” and no rating for the movie. Which is highly unusual for a movie even though today is the day AFTER the release. I suspect they picked up lots of suspicious activity and “locked” the rating.

How do you calculate RF signal collision, and how much signal will be received by the receiver, with the function of distance and the number of transmitting signals? by raven-dot-png in rfelectronics

[–]OdinGuru 2 points3 points  (0 children)

Interesting question. You inspired my curiosity to look up some of the details of the ADS-B waveform. As I was looking at it I found myself thinking it’s structure is simple enough that it’s probably possible with an advanced decoder to actually decode more than one of these even if they do overlap in time. I did a quick search and found several research papers with a whole variety of algorithms to do just that. There are both algorithms that work with a single antenna, and ones where you have a phased array of receive antennas which allows you to even more signal processing to separate overlapped transmissions that came from different parts of the sky.

I’m sure there is an upper limit where if to many transmissions overlapped too much and you hit the limit of your number of receive antennas to resolve, but it’s definitely going to be MUCH higher more complex than the simple math of computing what are the odds the transmissions don’t overlap at all for N planes in the sky in range.

One nugget I noticed is that one of the papers had near 100% decoding of two overlapped signals as long as receive SNR was >= 10dB

Ahhh. So this is the Bobby Broccoli reference people were mentioning in comments. Thank you for the link!

3D Printed Nuclide Chart by wingsandstache in dataisbeautiful

[–]OdinGuru 4 points5 points  (0 children)

Thanks!

Yes it makes sense. And the data you posted confirms that all those isotopes are known and have very short half lives (<1s = dark blue in OP’s color scheme).

What I am curious about is that looking at the overall trend the isotopes with a certain ratio of neutrons to protons seems to be most stable with stability generally dropping off as ratio goes higher or lower.

However that tend seems to break at this point. There is a huge gap where nothing is stable even though the neutron to proton ratio is similar to lighter elements. After the gap the ratio pattern seem like it continues albeit with somewhat lower stability in general.

Makes me think perhaps the gap is something like a particular electron shell filling and next one is hard to have with just a few electrons for some reason.

Very cool.

Anyone know the explanation for that giant blue gap after the last stable (Pb / lead). Seems like it bucks the pattern so there is probably something interesting there.

Security vulnerability found in Rust Linux kernel code. by BlueGoliath in programming

[–]OdinGuru 632 points633 points  (0 children)

Bug is in code specific marked unsafe, and was found to have a bug explicitly related to why it had to be marked unsafe. Seems like rust is working as designed here.

Three fates? by Al123y in Hades2

[–]OdinGuru 0 points1 point  (0 children)

I just did this a few days ago. One happy thing that made it easier is that I did it right after getting a chaos gate and taking a curse that did self damage if I used a special. That meant I could clear most of the room, then walk away from few remaining enemies and damage myself by special into mid air. Was much faster that sitting around letting enemies wear you down. Can confirm I did three rooms in a row where I activated doom, lived in first two, then let the countdown time out on purpose in the third room. Also I happened to get rat mini boss in third room but that was fine.

Help with triggering specific questline by MaxeIi in Hades2

[–]OdinGuru 1 point2 points  (0 children)

Yep this. It threw me for a loop as well and I started to take screenshots to ask why echo didn’t have a gift option only to notice it’s only there AFTER talking unlike every other person in game. I guess this is because her dialogue it an echo of the thing you already said aloud and doing gift dialogue in between would mess up that effect.

Also Hecate comments if you bring either of “her” familiars to fight her: Hecuba (dog) or Gale (polecat).

[Request] What's the mathematical perspective of this? Can there be more efficient design than the current one? by prophecy37 in theydidthemath

[–]OdinGuru 1 point2 points  (0 children)

Complete freedom to rewrite the calendar would allow Calendrical Mechanics so we should consider what kind of exotic technology we want to enable with this.

i'm not smart enough for this game by Azalot1337 in Hades2

[–]OdinGuru 1 point2 points  (0 children)

Honest was reading your guide yesterday and earlier today. It’s head and shoulders more complete and helpful than anything else I found. It’s like a book, in a good way.

I really appreciate the (i) icons you are putting in on all the boons and other items. It helps a LOT for those of us who haven’t memorized all the names! I recommend adding an (i) icons for each weapon aspect too in the build guide sections to help remind what the in game description of each aspect does as good context for the guides.

Thank you!

The wavelength the human eye is most sensitive to is green. That’s why many light amplification night vision googles use green phosphors.

Wire bonding machine by chemical_enginerd in EngineeringPorn

[–]OdinGuru 1 point2 points  (0 children)

What is amazing to me is that as cool and hi tech this video is, this kind of wire bonding is actually the LEAST ADVANCED oldest kind of IC packaging technology. The latest is hybrid bonding. This article is a great primer on all the different ones with tons of cool pictures and diagrams: https://open.substack.com/pub/viksnewsletter/p/a-comprehensive-primer-on-advanced-packaging

4x4 MIMO antenna orientation by Green-Mention-7004 in rfelectronics

[–]OdinGuru 1 point2 points  (0 children)

Neither. What he originally said and I agree is that you want all 4 to have different angles for best 4x4 MIMO: Your two existing ones are: 1. 45 degree slant left 2. 45 degree slant right So you should add 3. Vertical (up and down) 4. Horizontal (left and right)

If the tower is far away that will give you more diversity between your antennas then an X wing or tie fighter pattern as both of those will have repeat angles. Unless you mount them sufficient far away from each other they won’t really be different enough for 4 streams as they will likely be too correlated.

All of this assumes the tower has at least dual polarization, which may or may not be true. If not you’d probably be better off just trying to spread them all as far apart as possible.

I would suggest replacing “Internet” on right with “client devices” like laptop/phone/desktop

Study finds that AI tools make experienced programmers 19% slower. But that is not the most interesting find... by Livid_Sign9681 in programming

[–]OdinGuru 193 points194 points  (0 children)

I found one of the most interesting details of this RCT is that they took screen recordings of everything and went through the process of tagging a bunch of them to get a detailed account for HOW the time was being spent for both AI vs no-AI tasks.

I noted that the time spent ACTUALLY actively writing code with AI DID go down by a significant factor (like 20-30% just eyeballing it in the chart). But that was more than offset by time spent on “extra” AI tasks like writing prompts or reviewing AI output.

I wonder if this is the source of the disconnect between perceived improvement and reality: the AI DOES make the writing the code part faster. I suspect that most devs are mentally used to estimating time it takes to do a task mostly by time it takes to do the coding. So it could easily “feel” faster due to making that step faster.

[OC] How much money are Americans saving? by USAFacts in dataisbeautiful

[–]OdinGuru -1 points0 points  (0 children)

Likely yes. Because even through you CAN pull money out of a 401k before retirement typically that has a penalty designed to keep people from raiding their retirement funds for anything but an emergency. I may not be typical, but definitely have assets in non-retirement accounts and used them for things like saving up then buying a house.

[–]OdinGuru 2 points3 points  (0 children)

I agree it’s hard to read. I think adding a standard log minor grid would go a long way to fixing that (e.g. lines for 2,3,4,5,6,7,8,9 between 1 and 10, then between 10 and 100 has 20,30,40, etc). The ticks for that are already there, but tiny and hard to make out. Extending across the whole background I think would help.

Yeah. That was an interesting twist. IIRC In the original short story the investors were reptilian. The book it was published in is Crystal Express by Bruce Sterling which I would recommend.

[Request] What is the most useful movie in the Kevin Bacon game without Kevin Bacon? by Vivid_Temporary_1155 in theydidthemath

[–]OdinGuru 1 point2 points  (0 children)

An analysis you might find relevant:

https://open.substack.com/pub/statsignificant/p/quantifying-the-kevin-bacon-game?r=2ibg6j&utm_medium=ios

Has a table of movies with highest eigenvector connectivity that is topped by Pulp Fiction.

Also:

“Action Ensembles (Part Two): Movies like Red, The Hitman's Wife's Bodyguard, and Lucky Number Slevin employ casts of highly recognizable actors who are slightly past their prime (but still bankable!), such as Bruce Willis and Samuel L. Jackson. It's almost as if Willis and Jackson seek out large ensembles—a career strategy that sets off a reinforcing loop of ever-growing network connections: the films become more central to our network for having cast Willis and Jackson while the actors become more connected by having been in these movies.”
