I have used XMPP for some time now and I tried Matrix for a bit, but have stuck with XMPP until now.
I found it practically very easy to set up a prosody XMPP server in a raspberry pi. In XMPP you have the core standard that is kept quite minimal and then you can extended your implementation using XMPP extension protocols (XEPs) in a highly modular fashion. This approach of building on top of a light core using well-documented extensions I like very much.
With Matrix, JSON is used instead of XML. I think that JSON is a nice format when trying to look under the hood at how the message data is structured. XML is a bit of a pain to look at in my opinion. And I think JSON might be more efficient in how it moves the data around. So, that is a big positive for me. But I Matrix appears to be more focused on being feature rich than on having a flexible modular structure. While it does have extensions, successful extensions do have a chance of being eventually integrated into the core protocol. This makes the core feel bloated to me, because I have very minimal requirements.
In terms of security, in XMPP you start with the core and then you select the type of encryption that you like (OpenPGP, OMEMO, etc). OMEMO encryption has plausible deniability built into its design, and for me, plausible deniability is a property that I consider important for messaging. The modular approach to XMPP also means that these are choices that one gets to make in an active manner, and the protocols are open protocols that come from outside of XMPP. With Matrix you get their encryption protocol as part of the core - it is a protocol that they designed and that you need to accept to use their tool with encryption. It is probably a good protocol, but I don’t think it has plausible deniability built in, and that’s a choice you did not get to make.
As for moderation, I don’t know. Do they mean moderation tools, or the actual absence of moderators and unmoderated communities? Because the latter is more a property of the people using the tool that the tool itself. You can have your own private communities.
If someone asks me, I could recommend Matrix but would rather recommend XMPP, depending on what they are looking for specifically.
I’m not sure about the laser from the article, but I know that the Extreme Light Infrastructure project has a few pretty strong lasers.
The L4 Aton in Romania produces a single, 1.5 kJ, 150 fs pulse every minute - so peak power is 10 PW (1500 / 150E-15), but 1.5 kJ over a full minute is only 25 watts.
ELI also has the 2 PW High Field (HF) Laser laser, in Szeged, Hungary. This one gets the 2 PW with a 10 Hz rep rate, 17 fs pulses.
If they can send me over the second half of my thesis I would appreciate it enormously! 😀
The analytics tools that I am personally uncomfortable with involve dynamic, changing forms of data. I run GPSLogger on my phone (without a SIM card) and continuously log the GPS data to a text file. This data is then synced to my computer when WiFi is available. I can display this data on a map using gpx-viewer, and show very detailed tracking data of myself.
I have explored this map with some friends/family. They get to see a time-stamped movie of my life - my trips to work, to the shop, when I go out, if I go on a trip, etc. The data displayed in this manner is somewhat intimate, personal information. Anyone I have shown this to has said that they would not be so comfortable with such a map of their lives existing… Well, if they are carrying a active phone with a SIM card, it does.
To think that a company like Google can own such a map for a very large number of people makes me uncomfortable. On top of that, each of those map trajectories can be associated with an individual and their personality… They have the ability to pick out specific trajectories on the basis of the political ideologies or shopping behaviors of the personas behind them. This is extreme. I am of the opinion that the convenience afforded by a these technologies does not justify the allocation of that super-power to the companies that enable the technology.
A few years ago Facebook enabled a “Graph search” feature. This allowed users to create search queries such as"Friends of friends of X who like the page “X” and went to school near Z". That tool seemed super cool on the surface, but it quickly became obvious how something like that could be easily exploited. Later on in Snowden’s book I learned about XKeyscore from the NSA, which is like an extra-powerful no-consent-needed graph search that is available to some people. This is not just targeted ads.
I guess that what I am trying to convey is… For me, making the privacy-conscious choice is about not contributing to the ecosystem of very concrete tools that give super-powers to groups of people that may not have my best interest in mind. In my mind it is something very tangible and concrete, and I find many of those convenience tradeoffs to be clearly worth it.
Is the fact that I recognize this comment evidence that I use Lemmy a bit too much? 😅
I think we might see one or more “trusted fediverse” groups emerge in the next few years, with instance admins making commitments to security controls, moderation, code of conduct, etc.
There is now at least one system in place for admins to vouch for other instances being non-malicious, and to report suspected instances. It is called the fediseer: https://gui.fediseer.com/
I have the Tianje MF903 (https://nl.aliexpress.com/item/32719535459.html), which I bought early 2022.
But just now I have done a search and I see many more pocket wifi routers now. Unfortunately I can’t tell you if they work well, or if it is also possible to change their IMEI easily. The one I have is functional, but it doesn’t have a very long battery life.
Almost all countries require official authentication to activate a SIM card.
Fortunately not in the Netherlands. I don’t think that’s the case in the rest of the EU. I can use free sim cards as much as I want!
When communicating with cell towers, a phone will also broadcast its unique IMEI identifier. So, even if you swap the SIM card every day, your IMEI is still being broadcast the same.
Changing the IMEI of a phone in the EU is illegal, unless the manufacturer consents: https://www.legislation.gov.uk/ukpga/2002/31/section/1
So… I have a Chinese 4G mobile router, and the manufacturer gives me the permission to change the IMEI as it is an integrated feature of the device. I use that for my data. The data codes I purchase small quantities in bulk with cash, and I can access the router via its ip from my phone’s browser to send the SMS messages to activate the data codes as needed. Since WiFi connections are abundant around here I keep these codes for emergencies. I can go a few months some time without activating data codes. I mostly use them when traveling internationally.
I don’t know if this mindset will hold true with the new owner of Twitter though. I would assume Elon will do far worse things with the data.
I don’t know much about Elon Musk. But he strikes me as someone who would want to extract as much value as possible from data, and not as someone who thinks user privacy is something important to protect. Is this a topic that he has publicly spoken about?
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 am privacy conscious and care about privacy even though I don’t care too much about my own personal privacy just for privacy’s sake.
Privacy advocacy runs deeper than just protecting your own data. Convincing someone to care about “their privacy” is more straightforward when they face a real threat. For example, a journalist in Mexico writing about a politician linked to organized crime has every reason to avoid being easily tracked. That person is not going to post their location on Facebook.
But most people aren’t under direct threat. If you read my texts, you’ll find casual conversations with family and dinner plans. I’m not afraid of someone showing up at my door, so I’m fine sharing my address to get a package delivered. Getting ads is a minor annoyance.
Still, I care about privacy. Not necessarily mine, but privacy as a principle. I care about what surveillance capitalism does to society. Even if my personal threat model is easy, I want tools and systems to exist for people with harder ones. Privacy is part of the kind of world I think we should live in, and its erosion usually points to larger structural problems.
So back to the question. It’s easier to convince someone to care about privacy if they feel directly threatened. But if they don’t, you need something else to make them give up convenience in the name of privacy. That something is ideology. You’re asking how to shift someone’s ideological framework. That’s hard, and not something you can do for them. You can recommend good material, share your reasoning, explain what led you to care. But they have to engage with the ideas themselves. Like with exercise, you can’t build someone’s muscles for them. You can’t implant the ideology, but you can create the conditions for it to take root.
