"In einem Gastbeitrag im Politmagazin Cicero behauptet der ehemalige Chefvolkswirt der Deutschen Bank Thomas Mayer, dass ungebremster Temperaturanstieg der Weltwirtschaft kaum schade. Das ist reine Wissenschaftsleugnung."

THE #CICERO #RIOT OF 1951

To be wronged is nothing unless you continue to remember it.

#FOCUS und #Cicero, die mir im #Presseclub erzählen das mit der Umstellung beim Heizen etc. „ginge für die Menschen zu schnell“,¹ werden sich aber wundern, wie viel schneller so eine Flutwelle ganze Dörfer wegreißt.

Auch Ernteausfälle und Wassermangel werden sich nicht einfach um 10 Jahre verschieben lassen, damit sich die Menschen schön langsam dran „gewöhnen“ können.

__
¹wo waren die Artikel, die vor 30 Jahren gefordert haben, das mit der Umstellung _jetzt_ langsam zu beginnen?

The more choices we are willing to make, the better we get at making them.

Popular theology ... is a massive inconsistency derived from ignorance.... The gods exist because nature herself has imprinted a conception of them on the minds of men.

Today's random #Discogs choice Cicero and Heaven Must Have Sent You Vack To Me 12" 1991. Sounds suspiciously like the Pet Shop Boys. Investigates.... its on their record label. Spaghetti Recordings. This explains everything.

Wow! After a really tough week work-wise, what a great day to start the weekend.

Finished a major milestone on #Cicero / #Ginlo_II. Only two big work-packages left, all the others are minor topics. And this milestone was really huge with so many great enhancements.

But more importantly, after finishing work, I went to my #HappyPlace #PeraMeze - again.

But this time I was joined by two wonderful 15-year olds. One of them ("J") is a child of a very good friend of us and the other one ("F") is their closest friend.

I know "J" since their 2nd birthday so we know and like each other a lot. I had never met "F" before thus that was a bit of a question-mark.

Today was their last day at our place in Munich. Tomorrow morning they are both traveling back. In the meantime, I got to know "F" better and we realized we did like each other. She also isn't as shy as on the first day with us anymore.

Assuming they had a great time here and hoping to top it off with a nice dinner I invited them to my Happy Place for dinner (unfortunately, #LoveOfMyLife was/is still a bit sick, so she could not join us).

What a wonderful evening we three had: at one point at Pera "F" and "J' start laughing out loud. So, I asked what's up...
F: "I think the girl working here is really beautiful! But 'J' says I can't say someone is beautiful when they are a girl."
Me: "Why, J?"
J: "I didn't say that. Of course you can say they are beautiful, regardless of whether they are a girl or a boy!"
Me: "???"
F: "Well, I think - umm, - you know, I am bi, so that's maybe why J says so."
Me: "???"
F: "Oh, I am bi, you know, imdat, LGBTQ...?"
Me: "..."
F: (a bit hesitant now)"Well, you know, LGBTQ-parade? Yeah, I am, 'B'..."
Me: "You DO know WHAT I am, right? J? Didn't your Mom tell you?"
J: "What?"
(me takes out iphone, searches for definition of non-binary, shows them)
J: "Oh, yeah. Mom told me, yes. No problem, no worries..." (turns to F): "Yeah, imdat is non-binary" (hands over my phone to F; F starts reading, eyes get bigger and bigger - 😳😳😳)
F: "..."
... 😂😂😂 ...
Then the evening turned to an amazing, wonderful, gorgeous, awesome dinner + walk at the #Isar + sit at the Isar + dance to some music at the Isar + talk about difference between bi- and pansexuality especially wrt to cis and trans, about trixic, enbian, ...

"F" was so amazed to meet an "older trans non-binary", they completely opened up - to me and to "J" - and we three became probably friends forever: two 15-year old cis + 54-year old trans non-binary person (in case of "J", nobody really knows whether *they* are cis, trans, cis-bi, cis-pan, cis-...; I think not even they themselves know that yet, but atm, they seem to insist on being cis-het, though all the signs show otherwise...)

You probably guessed it: both are, according to them, cis female...

I don't think this was the last time they came to Munich😍

Oh, not to forget: I was then farewelled by one of my beloved friends (I call them friend now because we exchanged enough history to call each other friend) working at Pera with the words: "Come here you spirit of my soul" and a huge, huge hug...🥹

In #Cicero / #Ginlo we all messages are E2E-encrypted. For historical reasons we still use AES256 CBC. So, messages are always encrypted using CBC.

But when I receive the messages, I decrypt and re-encrypt them with a local Account-key. So, each device on which you receive the message has its own AES256 account key with which local data (database as well as attachment content) is encrypted.

This way, we can protect your communication in-transit as well as at-rest/

So far, so good. For local storage we also used to use AES256 CBC with its own IV.

Today, I decided to switch to AES256 GCM with IV and AAD. This has a few benefits:
- HW-supported encryption / decryption on iOS, Android, macOS
- Parallel encryption/decryption: multi-threaded in native code or `compute` in pure dart
- Built-in Verification using Mac/authTag
- And also slightly safer than CBC wrt certain attack vectors

The beauty? Each encrypted data has its own authTag stored separately so that we can also verify integrity of each data item.

While switching to AES-GCM, I also added streamed encryption/decryption for files. This way I can encrypt/decrypt directly from a file into another file without much memory use. This way, we can now (technically) support attachments as big as approximately <Free space on local disk>/2.2.

And yes, it is absolutely super-fast. On iOS/Android/macOS, we achieve about 120MB/s with CBC but 1-1.5GB/s with GCM, including Mac-validation.

On Windows, we "only" achieve about 100-500MB/s (depending on CPU), because there is no native GCM-chip-supported library there.

All in all, it was a difficult week because I had to first introduce "device coupling" (adding device to your account) BEFORE switching encryption method.

Now you can install the new client on a second device, add it to your "old" client, transfer the account to new device, delete on old device, and then transfer back to old device. This way, you easily switch from old, CBC-encryption to new, safer and faster GCM-encryption.

YAY!
