Oh, I had not noticed that page. I was hoping getting the NiDAQmx (https://www.ni.com/en/support/downloads/drivers/download.ni-daq-mx.html#494543) driver installed would be enough. So this means that even if I succeed it might still not support it 😅

I was quite naive when selecting this card. I knew nothing about PCIe and I figured it would be a very simple matter to read out the values...

I just found some videos about writing PCIe drivers from scratch, but since I know nothing about PCIe I have no idea about the level of complexity that it would take to reverse-engineer. I suspect that it might be a very difficult thing to do, maybe even practically impossible.

The human Y chromosome has been notoriously difficult to sequence and assemble because of its complex repeat structure that includes long palindromes, tandem repeats and segmental duplications. As a result, more than half of the Y chromosome is missing from the GRCh38 reference sequence and it remains the last human chromosome to be finished

Oh wow. This is surprising! I thought the full human genome had been sequence a while ago.

Ah, actually, I responded thinking that you meant the /c/mycology community.

I'm not the creator/mod of the uncle_ben's community, and the sidebar says "A community for the uncle ben’s mushroom growing technique.", so I am actually not sure. I think it would be fine.... Sorry!

Sure, what's wrong with bird seed tech?

[–] Sal@mander.xyz 5 points 1 year ago (4 children)

All fungi are magical ;)

The mycology community is more general in scope. Psychedelic mushrooms are not excluded, but there can be so much specialized discussion in that sub-category that is worth it having a more specialized community.

There is also the first community !uncle_bens@lemmy.ml dedicated to growing, but it is not very active.

I wiped all my data from a supercomputer by trying to 'cd' into a folder but making a typo and then running rm -rvf * from my home directory.

At least they kept backups... The system administrators were probably amused about who gets access

Nice to see he has had a graphics upgrade :p

For example I can go up to someone and insult them for all sorts of things - “you’re an ugly stupid worthless piece of trash” and that’s ok but I say “you’re a dirty [racial slur]” all of a sudden it’s different?

If it makes you feel any better, telling someone "you’re an ugly stupid worthless piece of trash" would get you banned from my instance too, so it is not so different.

I would like to make a list at some point with several community integrations and ask my instance's users whether they would like some of them installed into the instance. This application will definitely go on that list! I do need to take into consideration how many resources each of the apps consume, to make sure I don't bloat my server. But this one seems quite light. Is it?

Thank you for making this open source!

I'm not sure about Web Hosting. Many of us use a dedicated virtual private server (VPS)

I use https://serverspace.io, I think Lemmy.ml is hosted with https://www.hetzner.com/

These are servers that you access via SSH and can install the instance inside of it. I personally install using docker compose, but there are some other methods that are claimed to be easier. The cost starts at ~$5 / month. Currently I pay about $15 / month. You would then rent the domain name from a domain name registrar (I use namecheap.com) and ask them to point the domain name to your server's IP address.

No, there is no API to get the votes (https://join-lemmy.org/api/). If my understanding is correct, now that I upvoted your comment my instance will push that information. I'm not sure whether it pushes it to dandroid.app first or to all instances, saying basically "Sal@mander.xyz upvoted https://dandroid.app/comment/441785", and so every instance that has that comment can save my user ID in the "upvote" list of that comment, and that upvote is counted.

If only the vote direction was federated, then it would be very easy for me to spam the message "Upvote https://dandroid.app/comment/441785". I would not even need to create an instance for that, I just need to speak ActivityPub. And it would be more difficult to detect that I am doing that, because the database would only hold the vote count.

I don't think there is a way to ask an instance to reveal this list. You can only get it by directly querying the database if you have access to it. This is why if you fetch an older post or comment, it will arrive with a single or zero votes.

 

I slouch a lot, so my shoulders are a bit rounded at my neutral posture. I have tried to get into the habit of doing wall glides, stretching my chest, doing back exercises, and sitting properly. But after quite a few years of testing strategies, tools, and trying to build consistent habits, I usually manage to get two or three weeks of good progress but then fall back to the usual bad habits and my posture does not really improve.

Do any of you have any success stories about correcting your bad posture? I would like to learn from your success!

Hello!

I have procrastinated configuring the e-mail server for my instance. I am looking into it and it is not entirely clear to me how I should go about it.

I see that some docker-compose files have the following block added:

 postfix:
     image: mwader/postfix-relay
     environment:
       - POSTFIX_myhostname=${domain}
     restart: "always"

But I don't understand whether this is supposed to work out-of-the box (which it did not for me when I tried), or if I need to set up the postfix server as one usually would and the postfix-relay somehow makes the connection between docker container and the already configured server. Is there a guide for complete beginners? I could not find one in the lemmy docs and I have never configured an e-mail server before. I am reading through the postfix documentation and already got some basics but there is a lot, and I am not sure that I am moving efficiently towards the end goal 😅

 

I was thinking about how one could go about recovering their forgotten password without providing an e-mail address.

One way that I can think of is to have a section in one's profile for adding your GPG fingerprint. If you click "forgot password", the server can generate a code, encrypt it against your public key, and provide you with the PGP encrypted message block. You would then use your private key to decrypt the message, input the code, and change your password.

I have not seen this type of password recovery being implemented in other sites, and I am not sure why. Is it that people are just not interested in having this option? Or maybe those who can keep a their private key secure are also usually able to keep their passwords secure and well-managed?
