Sorry, I am in the process of moving and have not been able to keep a close eye, and the disk filled up. I have increased the disk size now, but I see some errors with the images. I need to sleep now but in the morning if it is not fixed I’ll figure out what is happening.
Is your friend alright?

Science@mander.xyz•Why this $10 spectrometer chip could bring real-time chemical sensing to wearables
1·3 个月前Yes, there is a lot of potential. There are micro-spectrometers available covering this range, like the MEMS-FPI type spectrometer or the multi-pixel arrays with filters (example: https://www.mantispectra.com/products). But this new kind of detector seems to come with higher resolution, faster readout than the MEMS-FPI, and more sensitivity. It is quite exciting, I’m curious to see if they commercialize it soon.

Science@mander.xyz•Why this $10 spectrometer chip could bring real-time chemical sensing to wearables
2·3 个月前I am not 100% sure, but I think that the designer bears the cost of the wafer yield.
The PDK is specific to the manufacturer, and I imagine that the risk associated with specific features is known and the yield range can be estimated. A design with more and riskier the features would lower the expected yield, and it makes sense that this risk gets passed onto the designer. The contract may have some protections for the case when the yield is significantly lower than expected because of the manufacturer’s fault. Just a guess though, it would be great if someone with real experience can answer.

3·3 个月前Very cool!
I also like that they included a device cost analysis. I think they used some aggressively optimistic assumptions (100% yield from the wafer) and large-volume procurement prices that I am skeptical of, but if true it is valuable info.

I could see the credits for “Everything’s Gonna Be Alright” in Deezer, but I am not sure about how exactly Deezer determines this: https://www.deezer.com/us/album/951602381
I would make use of a VPS to serve a directory with the files using Nginx. The VPS is ~$5 /month. You can share the ip or buy a domain name for ~$10/year. If you are not opposed to vibe-coding, you can probably generate the Nginx + HTML config to play through the songs without having to click them individually with little effort.

Asklemmy@lemmy.ml•Do you change the default luggage code from '000' to another code?
1·3 个月前Wait what, how do you know my code?

Asklemmy@lemmy.ml•What's something you used to dislike and what made you change your mind?
1·3 个月前Also: I use the timer very often, and I find setting a timer on a phone to be more awkward.

2·3 个月前Sport watches.
Combination of two tings: I used to think that wearing a watch was irrelevant because I could always see the time in my phone. And I did not want to have an app knowing how many steps I take.
What changed a few years ago: I stopped having a phone on me most of the time, so a watch became extremely handy for knowing what time it is, and I found out that Garmin watches work perfectly well without an app. So, now, I really like my watch. I am considering getting a fancier one with solar charging, and I even got a chest strap to improve measurement accuracy while running.
Very interesting! Thank you a lot for finding and sharing that, I couldn’t find any good info myself via online searches.
The song Everything’s Gonna Be Alright is a cover of the song from Sweetbox (1997) that goes by the same name and is based on Bach’s Air from Orchestral Suite No. 3…
I think that the rest are originals. Not 100% sure. I am surprised by how little information they made available, they just randomly dropped this with no context after almost a decade since the previous one. I ordered the physical album so hopefully it comes with some additional info haha.
All volunteer efforts are welcome, and using AI tools to support volunteer work is completely reasonable to me.
I personally value well-crafted human-made art more highly than AI-generated art. If someone wants to invest the time to create original icons and donate them, I am always very happy to see that!
That said, requiring unpaid contributors to meet a craftsmanship standard before they are allowed to help does not seem constructive to me. Volunteer communities usually work best when people contribute with the time, skills, and tools they actually have available.
A middle-ground alternative to AI-generated work is searching through Creative Commons assets, but even that still takes time to source, filter, adapt, and integrate. Expecting volunteers to always provide fully custom artwork or spend significant additional time curating assets does not seem like a fair expectation to me.
Sorry, I missed this! But I think that this is due to bots. From time to time, bots attempt to scrape the instance and this makes the site a lot less responsive.
I try to manually block these IPs, but sometimes new IP ranges show up.
Since my work involves sensors, I set up a continuous testing setup on a raspberry pi and got its IP whitelisted. I ssh into it when something is annoying to do in the Windows laptop.
I think that the TinyTapeout concept is super cool (https://tinytapeout.com/). In the past, it was not really feasible to design and manufacture a semiconductor device as a hobbyist… Unless maybe an extremely wealthy one.
Now, we have open source design tools, open process design kit, and the ability but small part of a manufactured wafer.
There are also now multi-project wafer runs for photonic chips at reasonable prices for startup/academia. I think these developments are pretty cool.




















… Yeah, that is understandable. Great find! And I like the picture of the gills a lot
