Discord isn’t exactly known for generous file-sharing limits, still, the messaging app offered a 25MB limit to free users. The company has now updated its support page to reflect the upload limit for free users has been lowered to 10MB.

25 MB wasn’t even enough to send a single full res screenshot of my desktop.
Its 2024 and we still lack the basic functionality of file sharing between peers without a corp dictator restricting and snooping.
Not that the functionality does not exist (p2p, literally) but if my grandma cant receive the family pictures its not basic.
That sounds like a you problem, because a PNG screenshot of my full 5120x1440 desktop is about 850 kB.
Interesting. Mine is 3840x1600 which should be ever so slightly less pixels.
I have noticed the content does matter, is your background native resolution or mostly one color?
3840 * 1600 * 4B / 1024 / 1024 = 23.4375MiB for uncompressed RGBA (four bytes per pixel).
That is, even if that thing was pure random pixels and would have to be stored uncompressed and you’d use a completely useless alpha channel you still don’t hit 25M.
Guys out here sending BMPs…
I specifically opened a few apps to break up any large blocks of one color.
Da fuck is your resolution?
That makes no sense. The 24MP RAW files from my camera at 25MB, no way a PNG or JPEG of a 4K (8MP) monitor are anywhere close to that big.
The issue is the absence of being able to port forward in a lot of places. UPNP exists on some networks but it’s usually disabled. But if we want actual peer to peer we’re going to need to implement some way to accept incoming connections EVERYWHERE.
IPv6
What about it
it doesn’t need NAT topology, at all. There is literally zero reason to use it. Direct P2P networking is so much easier over ipv6
Huh. I did not know that.
yeah, under IPv6 based home networking, you just assign a block of addresses to a home, 512 or something, for example, and then you just use a stateful firewall to do the same exact thing that a NAT + a stateful firewall would be doing on a traditional IPv4 network.
Nothing stops you from using a NAT if you felt like you wanted your networking to be more complicated for no reason. But you probably shouldn’t.
There are potential benefits for the anonymization of traffic (though this is probably easy enough to defeat by simply sniffing for all traffic across the IP block) a denial of service wouldn’t be super important anymore, as you could just engage in round robin across the other IPs, unless of course you DOS’d every IP all at once, but that would be super fucking obvious and trivial to deal with. Though it might kill an individual computer in the network due to traffic influx.
You could still engage in DHCP IP handouts, which would actually be beneficial in terms of traffic anonymization in this case. Especially on a high frequency basis. Similar to the effects of NATing on an IPv4 network.
Plus you could still grab a static IP address per device, and then just pass through firewall rules to allow external connections or whatever you please. No forwarding required.
IF ONLY WE COULD USE IPV6 WE WOULDNT BE HAVING THIS PROBLEM
YES FUCK YOU TOO COMCAST.
Gonna be real here, I’m in tech, there is no fucking way I’m gonna open my PC to the entire fucking internet. Vulnerabilities are everywhere and no code is perfect. Firewalls and nat help stop so many attacks from the start.
Even if ipv6 is common I will assume most implementations will be nat based.
IPv6 does not require you to open your machine to the Internet, even without making use of a NAT. Sure you get an IP that’s valid on the whole internet, but that doesn’t mean that anyone can send you traffic.
Comcast is one of the biggest IPv6 ISPs though?
not big enough.
Once an end-to-end, encrypted, connection is established between a pair of peers then anything can be sent through it. The establishment proces is generally facilitated by a server of some description so neither peer needs to allow inbound connections. (I’m a long, long way from being an expert on this and happy to be corrected - but this seems like network fundamentals?)
this is true, but the problem is that it’s really complicated, and not always reliable. Mostly due to NATing within the networks. Firewalls don’t help but you can get around those easily enough.
There’s no guarantee that you’ll get a reliable P2P network connection over a NAT unless one peer isn’t NATed. Which is unlikely.
TL;DR we would probably ddos the internet very quickly if we tried at the scale of something like discord.
Isn’t that what things like wormhole are made to deal with?
I kinda wish we could go back to the world of people hosting their own servers and having subsets of their homedirs on ftp urls. Of course none of that is really approachable to a lot of a people :-(.
I am considering this. I am just looking into what uses the least power.
What about encrypted messaging apps? Maybe your grandma can’t figure out Signal, but she could probably work out how to use WhatsApp (which uses the same encryption protocol) given how popular it is in some countries.
Reimplement the old WASTE client from the Nullsoft dude, this time with proper encryption and security and let’s call it a day.
