The NN approach sounds interesting, but there are no technical details and it might be hype-based marketing. Is anyone familiar with solid published work on applying ML/AI to optimize network control (or, as done here, optimize application parameters depending on network conditions).

Funnily enough, 10 years ago as a required entry step before being able to do a thesis I scribbled something[0] about distributed components with probes (some automatic, some with user feedback exactly as suggested here) and knobs driven by some fuzzy logic feedback loop, to be e.g applied to codecs and buffer size in an A/V streaming scenario† (possibly bidirectional). Concluded by saying you could get better, self-improving results by using genetic algorithms and/or AI such as NN. Was basically laughed at during defense and dismissed as being way too sci-fi. Got sick of such constant condescending attitudes and dumped research, pursuing my career as a software engineer. Had I pursued I could have been the author on such a paper you're looking for! Pretty sure I could have patented the shit out of this anyway but that's not how I roll regarding software patents. Now I lost the LaTeX source and Java code as well as the resulting PDF, and can't even download the thing as a memento since it's behind some stupid paywall.

† turned out MS launched instant play adaptative 1080p streaming some years later on Xbox 360, which was exactly that.

Their FAQ[1] states: Q: Will you have ads? Or sell my data? Or steal my beloved and enslave my children? No. So I don't think they will make money by selling data. [1] https://telegram.org/faq#q-will-you-have-ads-or-sell-my-data...

An FAQ isn't binding. What does their TOS say?

Why isn't the FAQ binding, do they disclaim it elsewhere?

Latency for a 56k modem was 180ms. Latency for a voice call on the same line was _much_ smaller. AFAICT, latency from my games console television to my TV is much higher...

300ms was not unusual on a 56k modem, if my memory serves.

180ms is what I got on WirePlay. The number is burnt into my brain. If the machine wasn't co-located, I can envisage it being a lot higher.

No app wil ever accomplish consistent good voice quality over the internet. Ever. For that it's too much of an unreliable network. You may try some calls over Signal, think Hey! This works well! until you hit a moment where the route between endpoints is flaky, attribute it to Signal while using another app for that same call at that particular point in time would have given the same result.

Only when QoS will be honored by all internet routers will we reach something that is consistently reliable.

I will definitely try this because I have trouble with all other voice chat services including Skype, WhatsApp and Hangouts. Often one of those three will work but not always. But the most annoying problem with any internet voice chat is not so much the quality but the latency. Landline phones have noticeably lower voice quality but one can still enjoy a conversation perfectly well. High latency, on the other hand, a…

>interleaving got enabled on my ADSL What is interleaving in this context?

Multiple data frames are interleaved and transmitted together. Good for error tolerance, since bursty noise doesn't wipe out a complete frame, but small parts of multiple ones, which then can individually be fixed by their Reed-Solomon error correction codes. But it adds latency, since the sender has to collect data from multiple frames to combine, and the receiver has to receive the entire block before it can be decoded, instead of transmitting each frame as it arrives.

I've managed to setup Telegram for most of my (non-technical) family - wife, siblings, mother (she doesn't even have a smart phone and just uses Telegram as a message client on her desktop. It's a very convenient way to share family related pictures). Voice calls are an excellent addition. If these could now also be extended to video calls, I could likely ditch Skype forever.

I could ditch Skype once i get video and screen sharing.

When you say "desktop" version, do you mean the cross-platform one that offers downloads for Win/Mac/nix, or the specifically Mac version that has a whole lot less features (at this point) than the cross-platform version?

He means the former, which is called "Telegram Desktop". The Mac-specific App Store version is a better app, but has been abandoned in favor of the (crappy) "Telegram Desktop."

Judging from recent updates it's still alive. The version in AppStore might be stale (not sure) but if you install the version from site (https://macos.telegram.org) you'll get frequent update.e

But I must admit that amount of clients is confusing.

>I'm using Telegram as my main messaging system but I hope they'll open source everything. A bit too late, now that you're using as your main system.

I'm using an Ubuntu Phone and Telegram is the only native messaging service app in it. I'm using UP for a beta-testing purpose so no big deal.

Really? I just get a white screen on mine. I see from reviews that others have the same problem.

I've never looked into logs though, so a fix might be obvious

But seriously how do they pay their bills? (I know VK brothers are super rich) There are bots that relay huge media files It's probably (imo) the fastest & most complete cloud based chat app Everything.. Literally everything you share can be retrived over the cloud & and now calling That must be super expensive infrastructure? No investors no monetization

If Snapchat is worth $30B, surely Telegram is way more than that.

snapchat covered a new market of communications and captured almost the entire young adult market. also it's already monetized. not sure telegram can compare atm.
