Thank you being around, bringing this nice community here, and helping with the federation!! 😁
If the timing is right, I would bring a mushroom grow bag with mushrooms sprouting.
If not… probably my radiacode gamma spectrometer and some of my radioactive items. Maybe a clock with radium painted dials and a piece of trinitite. I think that there are many different points of discussion that can be of interest to a broad audience (radioactivity, spectroscopy, electronics, US labor law story of the radium girls, nuclear explosions, background radiation… etc). As a bonus I can bring a UV flash light and show the radium fluorescence. Adults love UV flash lights.
I am also quite interested in this. It is not something that keeps me awake at night, and I am not particularly paranoid about it. But I find that working towards answering this question is a fun frame from which to learn about electronics, radio communications, and networking.
Since this appears to be something that is causing you some anxiety, I think it is better if I start by giving you some reassurance in that I have not yet managed to prove that any electronic device is spying on me via a hidden chip. I don’t think it is worth being paranoid about this.
I can explain some things that could be done to test whether a Linux computer spying. I am not suggesting that you try any of this. I am explaining this to you so that you can get some reassurance in the fact that, if devices were spying on us in this manner, it is likely that someone would have noticed by now.
The “spy” chip needs some way to communicate. One way a chip might communicate is via radio waves. So, the first step would be to remove the WiFi and Bluetooth dongles and any other pieces of hardware that may emit radio waves during normal operation. There is a tool called a “Spectrum Analyzer” that can be used to capture the presence of specific radio frequencies. These devices are now relatively affordable, like the tinySA, which can measure the presence of radio frequencies of up to 6 GHz.
One can make a Faraday cage, for example, by wrapping the PC with a copper-nickel coated polyester fabric to isolate the PC from the radio waves that are coming from the environment. The spectrum analyzer antennas can be placed right next to the PC and the device is left to measure continuously over several days. A script can monitor the output and keep a record of any RF signals.
Since phones are small, it is even easier to wrap them in the copper-nickel polyester fabric alongside with the spectrum analyzer antenna to check whether they emit any RF when they are off or in airplane mode with the WiFi and Bluetooth turned off.
What this experiment may allow you to conclude is that the spy chip is not communicating frequently with the external world via radio frequencies, at least not with frequencies <= 6 GHz.
Using frequencies higher 6 GHz for a low-power chip is not going be an effective method of transmitting a signal very far away. The chip could remain hidden and only emit the signal under certain rare conditions, or in response to a trigger. We can’t rule that out with this experiment, but it is unlikely.
A next step would be to test a wired connection. It could be that the spy chip can transmit the data over the internet. One can place a VPN Gateway in between their PC and the router, and use that gateway to route all the traffic to their own server using WireGuard. All network packets that leave through the PC’s ethernet connection can be captured and examined this way using Wireshark or tcpdump.
If one can show that the device is not secretly communicating via RF nor via the internet, I think it is unlikely that the device is spying on them.
You can take a lot of control by using search commands. Here is a list of commands for Google, for example: https://www.lifewire.com/advanced-google-search-3482174
By using commands like these you can narrow down your searches to the point that the impact of SEO is small. You give a much greater weight to the conditions that you have chosen.
It can be a bit of work to write a good search query, but the database that search engines search through is massive, so it makes sense that it would take some work to do this right.
Search engines like google aggregate data from multiple sites. I may want to download a datasheet for an electronic component, find an answer to a technical question, find a language learning course site, or look for museums in my area.
Usually I make specific searches with very specific conditions, so I tend to get few and relevant results. I think search engines have their place.
I used to it eat a lot of it as a child. But now that I think more about nutrition it is a rare treat for me. I don’t buy it nor keep any at my home, because if I buy it I’ll eat it. If I go out and eat fries I’ll usually eat them with mayonnaise. I do like the taste, especially in egg sandwiches.
Fair enough. I just looked it up and if the scale in this image is correct, I agree that the size of the hole looks small in comparison. I also looked at the security video of the crash itself and it is frustrating how little we can see from it.
Since this was such an important event and there seems to be a lack of specific pieces of essential evidence - either because of bad luck or because of a cover-up - I understand the skepticism. And I am not a fan of blindly believing any official narrative. But, without any context, if I see that photo and someone tells me that a plane crashed into that building, I would find it probable simply because the shape is so similar to the photo of the Bijlmer accident that I’m familiar with. A plane crash seems to me like a very chaotic process, so I don’t have a good expectation of what the damage should look like.
Maybe I’ll look for a pentagon crash documentary some time.
I don’t have much of an opinion on this topic, I haven’t really looked into it.
But as soon as I saw this image, the El Al Flight 1862 which crashed in the Bijlmer in Amsterdam in 1992 immediately came to mind. The shape of the hole is very similar!
This image shows the likely position of the Bijlmer plane during the crash:
The image you posted of the Pentagon seems to me consistent with what I have seen of the Bijlmer accident, and so the shape of the hole and the absence of wings in the photo does not persuade me personally that no plane was involved.
I made the switch when I got a new phone. So I kept both the old phone with android and the new phone with GrapheneOS. There was a transition period when I would bring both phones with me, just in case. Now my old phone is my “whatsapp” phone which I keep at home and turn on rarely. During the transition period I used my old phone number whenever I needed to provide my phone to use a service, but eventually I transitioned that to a VoIP. But, even then, many services will reject VoIP phone numbers, so I still make use of the old one.
I had to request a special scanner from my bank because the banking apps do not work with GrapheneOS. And I had to make sure that nothing important goes into my gmail anymore because google would request that I used my old phone 2FA in the most inconvenient moments, and also I don’t want to access google from my GrapheneOS phone.
I think that there are many annoyances that can and probably will happen if you try to jump right into GrapheneOS after having previously relied in the google/meta ecosystem. If you attempt to switch too quickly you might inadvertently lose access to your bank, and you might become suddenly unable to communicate with family and friends. My government’s online identification system requires that I use their app, which runs on google services, so I still have to use my old phone for that. And I have encountered situations in which the only reasonably convenient way to proceed is to download an app. For example, recently I registered for a gym that would then require me to use their google-store app so that I could identify myself when purchasing a physical card.
Thank you for that reference! Very interesting
Ah, cool! I got my 4 devices today and I have managed to play with them a bit. They are pretty cool! I was able to walk over to a park near my house and spoke with people across the world with no data in my phone :D
I ordered four of the simpler devices this weekend (LilyGO T3-S3 LoRa 868MHz - SX1262) and I have been reading about antennas.
Since I live in a city I am not super optimistic about the range. But I am still very curious about the concept, and I would love to be surprised.
After doing some search about antennas, I have decided to test the following combination:
3dBi 868MHz ISM Band Dipole Terminal Antenna for the LoRa that stays at home:
Sighunter 868 MHz to bring with me.
I also have a vector network analyzer (LiteVNA) that can be used for checking antennas, so I will also try to build some antennas myself. I doubt that my custom antennas will approach the performance of the professional ones… But I just find it such a cool concept.
Have you already gotten to play with it? What is your experience so far?
Yeah, I found out only after choosing that domain name… This TLD also gets penalized by the automatic e-mail spam detectors (like SpamAssassin). I wouldn’t pick the “.xyz” TLD if I were picking today 😅
This is what I think, but if anyone understands it differently please correct me.
Vertical scalability refers to scaling within a single instance. More users join and they post more content, increasing the amount of disk space needed to hold that memory, network bandwidth to handle many users downloading comments and images at once, and processing power.
Horizontal scaling refers to the lemmyverse growing because of the addition of new instances. The problem in this form of scaling is due to the resources that an instance has to use due to its interactions with other instances. So, you may create a small instance without a lot of users, but the instance might still need a lot of resources if it attempts to retrieve a lot of information (posts, comments, user information, etc) from the other larger instances. For example, at some point a community in lemmy.ml might be so popular that subscribing to that community from a small instance would be too much of a burden on the smaller instance because of the amount of memory required to save the constant stream of new posts. The horizontal scaling is a problem when the lemmyverse becomes so large that a machine with only a small amount of resources is no longer able to be part of the lemmyverse because its memory gets filled up in a few hours or days.
I think this underestimates how users will naturally gravitate towards more centralized instances, or they’ll give up because the bigger instances are closed.
(This is purely my personal opinion, of course!) In the scenario in which a few large instances dominate, the idea of the fediverse failed. One may estimate the likelyhood of success or failure given how they expect humans to behave, but in the end experiment beats theory. I think that for the fediverse to work a significant cultural shift has to occur, but I don’t think that it is an impossible shift. I would like the fediverse to succeed, and so I choose to take part in the experiment.
This also ignores that the system isn’t horizontally scalable at all, so scaling up gets even more expensive
Yes, that might cause some serious issues. The project is still in an early-development phase, and I don’t understand the technical aspects well enough yet to be able to identify whether there is obviously a fundamentally invincible barrier when it comes to scalability. My optimistic hope is that the developers are able to optimize horizontal scalability fast enough to meet the demand for scale. If it turns out to be impossible to scale, then only rich enough parties would be able to have viable instances, and that could be a reason for failure.
A small cloud server + a domain name costs less than a Netflix subscription. The developers have taken care to package lemmy in ways that are relatively straight forward to deploy, so a dedicated person with a small amount of experience can have an instance up and running in an evening. As long as a few percentage of users are willing to pay a netflix subscription to keep a server running, the financial burden would be spread.
This feels like one of those chain messages that we would get on Facebook asking us to do something like posting “I don’t give permission to Facebook to use my data”. Except that this time it is actually true!
I have added “_nomap” to my SSID and now I have to read the manual for the wifi extender, which by default appends _EXT to the SSID 🙄
I would much rather see a “_yesmap” opt-in policy!
I did not know of the term “open washing” before reading this article. Unfortunately it does seem like the pending EU legislation on AI has created a strong incentive for companies to do their best to dilute the term and benefit from the regulations.
There are some paragraphs in the article that illustrate the point nicely:
Thank you for pointing out Grayjay, I had not heard of it. I will look into it.
