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

Comparing the criteria of cars and messaging apps is futile.

I am certain that this was a metaphor, not an actual comparison.

I tried https://appear.in recently for a short call with a student and it worked well. A friend and fellow freelancer also uses it, he said. One good point about it is if you need to do a quick ad-hoc call - it is browser-based (probably uses WebRTC), and also does not need to you create an account or sign in. Plan to try it more in future, as well as TeamSpeak which I also mentioned in this thread. I had installed Wire too, both on PC and Android phone, but not tried it yet with anyone.

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…

>I always see these services talking about "crystal clear quality", but never latency, which is a shame. Maybe there is simply nothing they can do about it. 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. Well, the first problem at home is likely your wireless. Live in an apartment and you can pick up 30 other routers in your wifi search.…

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

Most people who I know use Telegram(me included) use it because it's frankly the nicest(fast, looks good) Messenger out there, not because of its security features. Personally I don't use the secret chat functionality; I would use Signal if I wanted to communicate securely.

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).

Can anyone familiar with the matter say how secure is the 4-emoji verification code?

> Thanks to this modification, it becomes possible to prevent eavesdropping (MitM attacks on DH) with a probability of more than 0.9999999999 by using just over 33 bits of entropy in the visualization. These bits are presented to the users in the form of four emoticons. We have selected a pool of 333 emoji that all look quite different from one another and can be easily described in simple words in any language. 33 b…

That would be low if we were considering a long-term key. It seems fine for a one-shot authentication token? Eve is going to have to MitM a lot of calls before she guesses this token correctly.

Correct, last article I recall reading about deciphering VBR from packet size alone was something in the neighborhood of 50% success rate.

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

Because 50% of them won't be understood?

My problem with Telegram is I want to use it but they wont let me. I use a budget phone service (freedompop) which apparently is technically voip, but I did not know until I tried to register for Telegram with it. They refuse to send me text verification. Wont work with my google voice number either. WhatsApp does not have this problem. And what if I want to use Telegram on desktop only? Why do I need to verify a phone number?

I'm not an expert on routers but if I was in the market I would look at the Wirecutter. I find their recommendations pretty good.
