Telegram is superior to Whatsapp from every perspective except for its smaller user base. However, how can you take as unbiased a comparison table that uses adjectives as "Incredibly fast loading times", "UNRIVALED", etc.?

The encryption they claim to use. Not saying they don't, just saying it's only "sort of" superior on encryption, given this caveat.

I happened to be reading a comparison of Telegram and Whatsapp this morning [1]. I've never used Whatsapp, is it really this bad or is the reviewer clearly a massive Telegram fanboy/girl? [1] https://info.seibert-media.net/display/Atlassian/Comparison+...

Well, there is some truth to it, but as a user of both I prefer whatsapp since:

1. most of the features that whatsapp lack are features I find annoying in Telegram.

2. Whatsapp is encrypted by default, which Telegram is not. I don't think I have ever used a secret chat, despite having oven 50 people with whom I regularly talk to over Telegram.

The client being open source is somewhat of a stretch. They have released many new versions, yet the github repo hasn't been updated in 7 months.

I think a while ago someone on HN suggested emoji as a joke as a more information-dense and internationalized alternative to numeric or alphanumeric verification codes. I don't know about security, but if this uses all 1,088 emoji from Unicode 9.0, then four emoji have about 40 bits of information.

They say they are using 333 emoji to represent ~34 bits.

33.52 bits to be precise, which is where the many-nines claim comes from: 1-(1/(333^4)) = ~0.999999999918

In a world full of bloated Electron HTML5 / JS "desktop apps", I'm very happy to see Telegram on Windows is a native app (Qt). It feels so incredibly responsive compared to everything else.

> Telegram on Windows is a native app (Qt) I thought Qt still bypassed the native user interface and drew all their own controls?

That doesn't make it a non-native app. They're still just leveraging direct platform APIs under the hood.

Native these days seems to mean "without a web browser under the hood".

A very well-known cross-platform GUI library. If you google qt, the top hits are the official website and Wikipedia. Without clicking any link, the descriptions would have given you an answer.

I know what it is, it's just not lightweight.

Ah, sorry I misunderstood you.

Have no fear, @tptacek will come and show us the true way, the Signal way. All praise @moxie!

I'm still curious to hear Moxie/OWS' take on the Wire issue, where they supposedly demanded $2.5mln for implementing the Signal Protocol (which is open source) and using source code where the documentation lacked (which is open source).

Does anyone have an opinion on the new "three-message modification of the standard DH key exchange" they introduced for calls? From their API doc: https://core.telegram.org/api/end-to-end/voice-calls#key-ver... > Party A will generate a shared key with B — or whoever pretends to be B — without having a second chance to change its exponent a depending on the value g_b received from the other side; and the impostor wil…

That just sounds like ZRTP to me, from the short description in your comment.

The same goes for Telegram. The android client hasn't seen any updates to it's github repo since sep 2016.

And, it is quite easy to verify that WhatsApp's encryption is doing what we think. A friend of mine managed to reverse engineer their protocol in 2012 in less than 24 hours, by himself. And there is quite a big chunk of the computer security market that would disagree with the claim that something has to be open source to be verifiably secure.

The funny thing is that Qt apps used to be derided for bloat (15MB of DLLs! 15MB! ) but the rise of Electron has made Qt seem featherweight by comparison.

Yeah, I remember years ago when I was pondering writing a desktop app in Python and thinking "Python? It would be so bloated!", and nowadays nobody gives a shit about being able to load more than four programs at once.
