Asklemmy@lemmy.ml•Should Lemmy potentially add an hourly post counter to help users avoid flooding communities?
6·5 months agoWhile the issue of the inter-server protocol being overly chatty is very much real, putting the burden on the users isn’t a good solution.
The focus should instead be on improving the protocol itself and its implementation with better algorithms, batching, etc. I’m not super knowledgeable about the inner workings, but I feel like there’s still some relatively “low hanging fruits” in the protocol design (are activities properly batched? are they sent as linear broadcasts to all federated instances? could we use some alternative broadcast distribution, like binomial? etc) and implementation (is the data model leading to some expensive operations? are the SQL queries well written? could we speed them up some other way?).
I say this as someone who’s been running an instance for many years now, and can tell you for sure it has been a rather bumpy ride, as a small server. Running a good and fast server with lots connections is not cheap; not as much as it should, at least imo.
Ah, that’s a nice one!

2·5 months agohttps://en.wikipedia.org/wiki/Compose_key
It’s a key that makes the next 2 or more keystrokes be dead key inserts that combineinto some character otherwise impossible to type.
In my case, my keyboard had a ≣ Menu key which I never used, so I remapped it to Compose.

11·5 months agoYou’re correct, but that’s like saying along the lines of manufacturing a car is just bolting and soldering a bunch of stuff. It’s technically true to some degree, but it’s very disingenuous to make such a statement without being ironic. If you’re making these claims, you’re either incompetent or acting in bad faith.
I think there is a lot wrong with LLMs and how the public at large uses them, and even more so with how companies are developing and promoting them. But to spread misinformation and polute an already overcrowded space with junk is irresponsible at best.

3·5 months agoI’ve been getting into the habit of also using em/en dashes on the computer through the Compose key. Very convenient for typing arrows, inequality and other math signs, etc. I don’t use it for ellipsis because they’re not visually clearer nor shorter to type.

14·5 months agoThat is not really true. Yes, there are jump instructions being executed when you run interference on a model, but they are in no way related to the model itself. There’s no translation of weights to jumps in transformers and the underlying attention mechanisms.
I suggest reading https://en.m.wikipedia.org/wiki/Transformer_(deep_learning_architecture)

Privacy@lemmy.ml•Sign the petition to get proton to accept Monero for payment.
1·5 months agoGood point regarding ecommerce shops, was not aware they were sold there!

Privacy@lemmy.ml•Sign the petition to get proton to accept Monero for payment.
1·5 months agoThis would be really neat, however it’s not trivial to sell those everywhere. If you’re lucky to live in a country or even city where they can get those to, you’re golden. If you don’t, you’re screwed.
Unfortunately, as much as I love the idea and tech behind Monero, actually accepting it is not practical at all, as the coin is used a lot for criminal stuff and is thus very strictly followed by many agencies. We don’t know if they can break it, but even they don’t, businesses can get a rough treatment just for accepting Monero. It’s perfectly understandable if they’d rather not do it.
Adding onto what’s already on the thread, you can try look at the newer Element Call, which is an implementation of Matrix’s native calls.
I’ve been using it a bit recently, since Jitsi seems to have stopped working reliably for me (to be frank, I’ve not put much effort into debugging it yet). It works well, but it’s still early stage, lacking some features Jitsi has. If that one works for you, I recommend you stick to it.

Asklemmy@lemmy.ml•What is your favourite open source software that you discovered in the past year, that you can no longer live without?
2·1 year agoconduwuit is a fork of the less “energic” conduit.rs software, and both are maintained by the community, not by the Element people, like Dendrite.

Privacy@lemmy.ml•Is there such a thing as a privacy driven credit card?
2·1 year agoYeah withdraw cash from an ATM and use it. The system sucks, but it’s not trivial to change for a myriad of reasons.

Privacy@lemmy.ml•Is there such a thing as a privacy driven credit card?
3·1 year agoThere’s no real way to do it. Unless you know someone who can trade you XMR<->cash and you somehow convince your employer to (break laws and) pay you in those forms, you can’t avoid it. At some point, you’ll have to get money on a real bank account, which requires real information to open.

Privacy@lemmy.ml•Is there such a thing as a privacy driven credit card?English
2·1 year agoAs far as I know, modern cards don’t just send your CC info to terminals, they do some form of a cryptographic handshake (probably a pubkey signature or similar) which gets confirmed by your bank. I believe Caveman was talking more about online shopping, where you have to enter your card number, expiration date, CVC and often your name too.

31·1 year agoThat’s why I love virtual card systems like MB NET. You just generate a random virtual card for every purchase (or a recurring one for each subscription vendor, for example) and move on. Your bank still knows what you’re doing, of course, but vendors can’t correlate anything. Preventing your bank from knowing where you’re spending your money is much harder, for very practical reasons: fraud detection. The only real way is to use a secure crypto coin like Monero, but very few places accept it and you still have to deal with volatility.

Asklemmy@lemmy.ml•With all the bad stuff happening in the world like politics war racism homophobia etc. What is some good news that isI happening that we don't read or see about?
5·1 year agoYeah, I am lucky to live in such a country and it’s amazing. The state and municipality each subsidised part of the purchase, so I ended up paying 300 something euros to install 3.5 kW of panels. My electricity bills are almost non existant during summer and also cheaper during winter. To make it even better, anytime I’m not using the produced electricity, it gets sold to the grid, even if pretty cheap, rebating on my next billing cycle.
Ah right, Molly. Have yet to tried it, but looks interesting.
I think I’m too afraid of moving my main stuff to Molly, lest I lose something :P But the UnifiedPush and multiple mobile clients is enticing.
Yeah that’s a bummer. Signal has multi device support but only for desktop and iPad (yeah, not Android tablets), but you always need to have a master phone device.
It’s been an issue for so long, but this is Signal, they do whatever the f they want.
encrypted email
Besides being a form of messaging (so the text somewhat contradicts itself), typical email is a deeply insecure protocol.
In my opinion, it’s probably impossible to secure without making a new protocol or making such drastic changes that it might as well be considered one.Here are some key concerns regarding the usual PGP-powered encrypted email:
- Email, at a simple level, works much akin to physical email — there’s an “envelope” containing important info regarding the communicating parties, which can’t be encrypted, otherwise the mailing servers wouldn’t know where to forward the messages. This essentially leaks a lot of metadata that can be almost as valuable as the message body itself.
- There’s no forward secrecy — one of the best cryptography features that has become pretty much a commodity in modern systems is forward secrecy, which prevents attackers from decrypting older messages after gaining access to one of the keys.
- While not an issue with the protocol itself, it’s the sad reality and we need to consider — most people use GMail, Outlook and the like, which ultimately need to read your emails in plaintext, for better or worse reasons (search is incredibly useful, but some big players don’t stop there of course :p).
- Another thing is the fact that it’s incredibly easy to have an imbalance of encryption, i.e. someone is encrypting their messages, but others aren’t. With the very popular email culture of quoting (be it top or bottom posting), an unencrypted party in the the conversation can leak important information.
- PGP is… peculiar, so to speak. I has a lot of issues, mostly stemming from its age (which could also be a source of robustness and security, due to being very battle-tested, but I don’t think that’s quite the case with PGP/GPG), tries to do too much and typically has a clunky UI, which impedes wider and proper adoption by less technically people.
This isn’t to say people should definitely stop using and promoting encrypted email, since it can be useful.
It’s just it gives, more often than not, a false sense of security and can lead less proficient users to send sensitive data through this medium which isn’t nearly secure enough for such use cases. Preferably, people with such threat models should opt for better alternatives, most suggested in that article (such as, but definitely not limited to, Signal, SimpleX, Matrix+Olm, XMPP+OTR/OMEMO, sharing files via MagicWormhole, encrypting with tools like age).On a slightly tangential note, I think someone should make a Matrix client with an email client interface. I started working on a new traditional chat client (completely nonfunctional still, very much in-dev), but I’ve been honestly thinking more and more about making one looking like an e-mail client, where there isn’t much focus on instant room-based chats, but rather on longer-lived 1-to-1 and list-like exchange of messages.
Yeah Mullvad’s system is better than Proton’s, since the latter asks you to place your username inside the envelope. Mullvad’s random token is better in that regard.

Disclaimer: I’ve never paid in cash on either of these services.




As others have also mentioned, Minoxidil can be effective at slowing or stopping balding, with daily application, though it isn’t immediate (may take a couple of weeks to start showing results). It can vary a lot from person to person, so give it a shot for a couple of months before deciding whether to commit or not.
