after a very quick google search, the top SO link had a comment pointing to this thread https://forums.developer.apple.com/thread/12885quote:Note Just as an aside, you can access peer-to-peer Wi-Fi without using Multipeer Connectivity. The underlying technology is Bonjour + TCP/IP, and you can access that directly from your app. The WiTap sample code shows how. you should read some links instead of... not.

I'm looking at low-latency video distribution, apparently ultra-low latency is 2-5s in video land with normal latency being ~30s. There are apparently different preferences for producer to  and for to consumer, the former being things like RTMP which apparently has low overheads and presumably happy to drop things quickly. Consumer wise MPEG-DASH and HLS are for higher latencies, RTSP and WebRTC are for lower latencies, I guess the preference is no data-loss and just queueing up video instead of real-time adaptive playback. h264 on Chrome is odd in that they will only support it if the platform has hardware acceleration for encoding.So I have a RTSP multicast feed I need to get into Chrome dotted across a single building. RTSP suggests consumers should be hanging immediately off it, although I'm not sure why that wouldn't be just RTP as media controls seem a bit redundant in a view-only model. As far as I can tell RTSP = RTP + media controls. Browsers have pretty much thrown out native plugins these days and alternatives such as NaCl & pNaCL are already dead whilst WASM is still limited to HTML 5 network connectivity. So a broker of some form is required, there are oodles of media servers that target high latency environments and so of no use, there is a niche of media gateways that simply unwrap RTSP to get the raw video and audio stream and allow you to repack into WebRTC: online education seems to be a popular market. There appears to be a few options and I've seen implemented two, and completely unrelated to Epic Games, in one media broker call Unreal Media Server. You basically unwrap RTSP like the media gateway, Yanus appears the goto option, but then wrap into WebSockets or WebRTC to send to the consumer. I think you could be super odd and wrap into a WebRTC data channel to feed directly into Media Source Exensions (MSE) instead, thus avoiding any limitations on the codec negotiation within WebRTC. It all sucks.

i wrote a video based cms around wowza media server and it worked good but i have no idea if it will check those boxes. it worked well though and was reasonably priced

they already have that and it’s called GKE seems like this is tooling for rolling your own functions as a service type of thing with event/request plumbing but also some other vague buzz wordy poo poo

I guess it's mostly about scaling up and down pods as well as aggregating logging and load balancing? idk there's also a bunch of stuff about event pipelines but that's separate to the bit about not managing any pods or servers

aws lambda is good for when you want to do something in response to an sqs message, an sns notification, a dynamodb stream event, a cloudwatch event or a kinesis message. it's garbage for responding to http requests tho. i assume 'knative' has similar characteristics

back when i was the admin of epic's internal white paper portal i tried a number of solutions but always wound up back at sharepoint with versioning turned on. if you enforce edit locks and such it works about as well as you can expect and it's probably the least normie-hostile thing available. any other document store i know of isn't really intended for direct use by normies, rather as a backend for software to be built on. don't cut off solutions just because its a meme to poo poo on microsoft. sometimes the least bad is the goodest

i will not play kerbal space program. i bought it and installed it a few years ago, stayed up for 48 hours straight playing it, and then uninstalled because otherwise that game would have taken over my life.
