Why, for the love of Satan, does this graph have only 2 data points per source?
Why use a line chart 📉 for that?
This is clear bar chart territory 📊.

Oh boy, what can’t we put ads in?
Can we get MtDew Green Lights with Coca-Cola Red lights?
The spacebar on laptops is free game, just asking for it.
It really is a shame that I can still buy bedsheets that aren’t branded with a corporate advertising campaign.
AGU Local 2, Messenger Hot Girls Union
Accidentally made a hot-girl union.
Now they can organize and demand higher quality pickup lines.
Thankfully RHEL/Centos/Fedora also get attention thanks to the large corporate influence.
Anything else can just be compiled from scratch, after spending 6 hours trying to figure out what ajfiwn-0-libs-dev is in redhat land, only to find out it was libfiwn-devel all along.
Who could have guessed that may-issue permits could be (gasp) abused!
I thought the police would be even and fair in their determination of who should get one, just like they are in all their other activities.
I am an engineer that has worked in the space industry my entire career, and here are my thoughts:
GOES and METEOR weather satellites transmit images publicly that are NOT real time, but are downlinked, processed, and uplinked for public broadcast. This is pretty simple and saves a lot of processing power on the spacecraft side. That’s important because the biggest constraints on spacecraft processing are: power budget, radiation hardiness, and thermal.
I was able to find an image of the actual satellite in assembly. From this we can guess that there is probably not more than a square meter of solar on-board, so we can give it a round 1300W of power. I couldn’t find any orbital parameters(If Gunter doesn’t have it, who does?), but given it’s main task is as an imager, we can assume LEO, and so this 1300W isn’t going to be constant since the spacecraft will most likely be eclipsed part of the time.
Generous 1000W average solar flux, generous 25% panel efficiency, 250W/h.
So lets look at rad hard processors. They have to be either shielded or run multiple and do voting, though even that isn’t fully acceptable as some SEU (single event upset) can cause permanent damage and leave you down a voting member. The latest and greatest RAD5545 advertises 5.6 giga-operations per second (GOPS) at 20 watts, so if we assume (artlessly, and likely incorrectly) a linear power usage, the 80 TOPS of the WJ-1A should need some 280kW. So we know they aren’t using a typical rad-hard CPU topology for their AI models. I see that Corel/Google advertise 2 TOPS per watt on their edge TPUs (Tensor Processing Unit).
So assume a large ASIC (application specific integrated circuit) at the same efficiency of 2TOPS/W, with 4x multiples for voting and we get a far more reasonable 160W. Still a LOT of power on orbit for such a small spacecraft, but actually possible.
So for thermal limits, do they run the TPU only on the dark side in place of their on-board heater? The have some white panels that might be radiators, but it’s hard to say.
Hard to say from these fluff articles. I really want to hear:
I expect to see more ML in space, but to be honest I did not expect it to be in such a small form factor.
The worst part is how confusing it was for older people, who were worried the whole app was going to not work.
Signal was upset that “oh well some people can’t figure out what’s SMS and what’s encrypted”, but that was kind of… good? You could give parents, grandparents, etc an SMS app that was easy as the old one, and secure with the right people.
Don’t get me started on the chat color fiasco. No signal, I SHOULD NOT CHANGE COLOR. I assign colors to people to distinguish them, I don’t change who I am based on who I talk to.
Robot vacuums are something non-tech people love, then they use the app and they don’t love it anymore haha.
Shout out to Valetudo, which saved the day on our chinese roombas.
I am not quite happy with how the current iteration of the documentation no longer supports DIYing the firmware, it is actually still possible and you don’t have to use dustbuilder.
Yeah I’m not super happy with Signal’s level of openness, but I also wouldn’t call it proprietary. It is open source and I could run my own server if I really wanted to, but that would just make it harder.
At the time we were moving from a walled garden to one of 3 encrypted OSS solutions, and I had all of them until we naturally coalesced on one.
SMS at the time didn’t work due to not having cell service, and while we “have” RCS now to solve that issue, I don’t know anyone who uses it.
Yes, this is correct.
I could not have used SMS for most of the day since I worked on the top floor of a multi-level basement. I had wifi and a VPN though.
At the time I moved to signal, Google Message, or chat or whatever was being replaced with Allo and Duo and everyone was pretty un-jazzed about the whole thing.
At the time I was changing to signal, I only had google messages on my desktop, so I would answer accumulated messages at home.
There was no cell service at work so SMS didn’t work, but I could use wifi.
In modern times, we have RCS so it’s kind of not really a problem anymore, but everyone I know uses signal now anyways.
I didn’t make it hard, I got Telegram and Matrix and met people halfway where I could. But naturally everyone I know just settled on signal since it also did SMS so it replaced an app rather than added one. Plus id didn’t feel like a “sign up” since it just worked. Those days are gone but the network effect is already chugging along.
I make the private option easier than the locked in version.
Homeassistant will let us see our locations, run lights, run media centers, control AC, etc. So why do you need Google Home or Google Maps Location Sharing?
Signal will let us chat over WIFI unlike texts, and I will answer it unlike a Google chat account. Before the SMS death it was easier since it did SMS and signal in one app, easier to convince someone if it can replace the old one and add new features.
I configure two SSIDs, one for things I trust and one for those I don’t. I can run firewall rules and add security on the backend where they can’t see it.
Tiktok you can run a campaign against it by saying it damages cognition, is harmful to youth, supports the CCP.
You can run a pi hole style filter list,ehich might break some stuff so you have to be willing to play tech support.
I don’t know anything about kids but it couldn’t hurt to teach them some simple skills like html so they get a taste for what’s happening behind the scenes.
It shouldn’t matter as long as the sites are developed only with open standards.
We already have webcompat for anything truly broken.
