I haven't personally reviewed it, but based on their previous inability to make principled cryptographic choices and resistance to critical feedback from actual cryptographers… I'm skeptical.

I don't choose my car for its seatbelts, but if they are broken, I reject the car.

Right, because you use seat belts every time you drive. So they are always a factor. I do not use Telegrams security features though, so whether they are any good isn't relevant to me(and many other people).

Whether you use them or not, intel agencies use their lack. This is the naïve "I have nothing to hide" dodge about privacy.

I'm using Telegram as my main messaging system but I hope they'll open source everything. That's the only way to fully audit the service. Telegram is not too bad but has too many grey areas at this moment.

I think at this point it's quite clear they are not ever going to do that. They actually stopped publishing their client source code and they aren't responding to any questions about that.

And the Desktop client[1] is kept very up to date. My biggest complaint is that they have stopped updating the API documentation [2] which has lead me to become a rather lukewarm telegram developer (though I still have a few projects I am work with)

> I've noticed latency get worse and worse on the Internet since I started using it in the 90s and nobody seems to talk about it. You're remembering incorrectly then. Dialup latency was in the range of hundreds of ms. Early high speed internet access also had higher latency than modern connections. If you have latency problems it's likely a problem with your hardware.

I don't remember dialup latency. I only remember it having low bandwidth. I'm talking about ADSL latency in the 90s.

Cable tends to have a higher latency than aDSL. I don't know if that's the tech or just over-subscription on cables part. The trade off is in the bandwidth allowed so people mostly gave up that feature in exchange for enough bandwidth to do other stuff.

>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.

I don't know much about the different router brands and models. Which would you consider to be some of the good ones?

A starting point for me: LEDE support

That's: https://lede-project.org or:“Linux Embedded Development Environment” - the new project born from OpenWRT. I've used it with some old d-link routers, and I'm quite happy.

The documentation is still not stellar, but it has gotten better, and the configuration more consistent. It's quite easy to set up ssh-access with a key, and simply get a copy of configuration files with scp - ready to set up identical configurations on new router installs.

As I already said, if I was concerned about intel agencies capturing my messages I'd use proper OSS encryption via Signal, not Telegram.

There simply are situations where I do not care whether my messages are encrypted or not, in which case I use the app that works the best for me, which in this case is Telegram.

Then why not compress really efficiently by just transmitting packet sizes?

Because 50% of them won't be understood?

On the other hand, if you could do it, you'd probably have invented a convoluted speech-to-text (where text is a index into a dictionary of words). Note that you would also likely lose things like inflection, voice, accent etc - so while it might work as a texting system with voice input - it would be a poor substitute for voice chat..

can you point to some examples where the resisted critical feedback? I've heard people mention this but haven't actually seen anything convincing yet

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…

The best phone voice quality is still ISDN. Digital all the way to the handset, and rigidly clocked with fixed delay. Switzerland has ISDN phones, and the voice quality is impressive.
