33C3 - Day 2

Good morning Hamburg! It's 10:00 in the morning an I am walking through the Apothekergarten towards the Congress Center. It's quiet on the streets.
In this moment I realize, that it's the time after Christmas. It's winter. It's the time of the year, where a lot of people took holidays to recover from the year, to reflect about all the things that have happened and that are going on. It's a time of peace.

Be excellent to each other!

I'm here at the 33C3 - The 33rd Chaos Communication Congress. It's awesome! 🙂

People here are very friendly. Due to general "Verpeiltheit" I've forgotten my Lenovo power supply unit. Also the nearby Saturn has none of those on stock (that's a shame! You have a Lenovo section but such crucial elements not on stock?!?)
Fortunately, since it's quite common I always find a way to charge it - From a huge power back with a lot of special adapters to some friendly people who borrow me their supply.
Lesson learned: If possible, always prefer a device that is quite common, so you can borrow equipment to and from other people.


There are still a lot of things going on. Stay tuned and remember: Be excellent to each other 🙂

Evernote wants to read your notes

Evernote recently announced, that some user's note will be subject to a machine learning process.

Although they claim to stuck to their Three Laws of Data protection, but the update is, that a Evernote employee may read your notes in order to check and validate the machine learning algorithms.

I personally do not like to have a machine read through my notes. There are other applications, where this might be useful, but not for my notes.

You can opt-out from this program in your personal settings.

In your personal settings in the Browser you can opt-out from this services



It seems that Evernote has changed the strategy to opt-in.

As a reminder: you can always encrypt part of your note using a password. Unfortunately you cannot encrypt a whole note or notebook at this moment.

works for me

The Motto of the 33C3 (Chaos communication congress) is "works for me"

works for me
A commonly used phrase by software developers to indicate that the bug reported by a user is not repeatable on their machine, and will therefore receive no more attention. Usually connotes a dismissive approach, where anything that is not visible immediately to the developer is „someone else’s problem“ and is therefore not worth fixing.

Like no other, the year 2016 pointed out how well „works for me“ works for us.
It does not. Mutual hate, envy, insensibility and exclusion have driven us apart.


Let’s break this vicious circle.
Let’s get together and live our utopia.
Let’s strive for something that works for all of us.

And let’s fight those, who will not let us!

Looking back at the GNU Philosophy and it's philanthropic approach that could work as well to other human beings. Or in a less complicated and more pragmatic way: All creatures are welcome - A reminder to be excellent to each other 🙂

The truth is that we have become a divided society of egoistic cry-babies, instead of solidarity and collaborative driven society.

Some really good things have happend in 2016, but must of the year was a frakking nightmare

2017 - Here we are coming, and we will try harder this time!

Why you should switch from mp3 to Opus codec

Opus is an advanced audio codec, first released in September 2012. It's now almost 4 years old and I'm astonished, that so few people know about it.

In a nutshell

Opus is much better than mp3 and you should switch to it as fast as possible.

  • OPUS offers better sound quality than mp3
  • OPUS makes the same audio files smaller than mp3
  • You can already use it on most of your devices

There is no reason at all you should still use mp3 and not move to Opus (or OGG Vorbis). Both are generally better in terms of audio quality and compression rate.

Opus - Some details

Opus is offering a significantly better audio quality compared to mp3 and even OGG Vorbis1.
In reality, there is no reason to still stuck with the old mp3 audio format. It was the thing of our generation to have music in a quite reliable, small data format on different devices, but it has become old and obsolete. There is no reason at all to stick to mp3, even OGG Vorbis is significantly better in compression rate, audio quality and it's a free codec, whereas mp3 is a non-free codec witch means, that every Software and device is charged some license fees in order you can use it.

According to 1 and 3 the audio quality of OPUS is much better than mp3 and compares even to HE-AAC.

Can I already use it?

Most probably.

Opus is build-in in most modern Browsers. It has build-in support in Firefox and Chrome, and also Edge is about to include it2 (another reason why Edge is broken). VLC supports opus and on Android you should find at least one player, that suits you and can play Opus.

In Linux it is available as a package and ships with most of the latest distros.

How to convert files from mp3 to Opus

For Windows users:

I've not found a suitable tool for the conversion of OPUS, but you can use freac to convert your files to Ogg Vorbis


To convert an mp3 on-the fly use the following snipped, and modify the bitrate to your needs

Das Schlimme an unserer heutigen Zeit ist, dass viele Menschen der Meinung folgen, in einem Nationalstaat ohne große Gebilde würde alles Besser werden. Europa hatte dieses System jahrtausendelang und durchlebte einen Krieg nach dem Anderen. Erst die Verbrüderung aller Völker Europas hat uns eine noch nie dagewesene Zeit des Friedens und des Wohlstands gebracht und wurde im Jahr 2012 mit dem Friedensnobelpreis ausgezeichnet für über 60 Jahre Fortschritt in Frieden, Konfliktlösung, Demokratie und Menschenrechte.

Wenn jemand wie Zeid Ra'ad al-Hussein, der Hohe Kommissar der Vereinten Nationen für Menschenrechte vor Leuten wie Geert Wilders, Donald Trump, Boris Johnson und Norbert Hofer warnt, so sollte das mehr als nur zum Denken geben.
Diese Leute sind nicht am Fortschritt der Menschlichkeit, der Brüderlichkeit und einer sozialen Gerechtigkeit interessiert.
Wer das noch nicht verstanden hat, dem kann ich nur raten, anzufangen nach Zeichen der Manipulation und Propaganda zu suchen und sich in sozialen Gruppen außerhalb seiner Komfortzone zu bewegen.
Rechtspopulisten, teilweise mit nachgewiesenem nationalsozialistischen Hintergrund, für die kann ich keine Sympathie oder auch nur Verständis aufbringen.
Wo bleibt der Aufschrei, wenn Hilfsgüter in Aleppo bombardiert werden? Wenn sich eine weitere humanitäre Katastrophe im Kongo anbahnt oder die MONUSCO Mission bedroht?

Was übrig bleibt, sind Krawallmacher und Unruhestifter, die das Werk einer zivilisierten, einer menschlichen und einer lebenswerten Welt eher zerstören würden, als ihre Bereicherungsgelüste aufzugeben.

Mir ist unverständlich, wie die Messlatte für ethisches Handeln so dermaßen nach unten sacken konnte.

Ich verlinke hier das Video von Zeid Ra'ad al-Hussein, der vor Populisten und Demagogen in Europa und den US warnt.


SPAM Mail: Nigerian Astronaut stuck in space

Sometimes I'm wondering if our University-Spam filter is really enabled. But once in a while, there are some really funny Spam mails around. This one is quite old and tells the story about a stuck Nigerian Astronaut, that is stuck in Space because the CCCP was breaking apart and so he was forgotten. Now they want to collect money in order to return back to earth 🙂

Dear Mr. Sir,


I am Dr. Bakare Tunde, the cousin of Nigerian Astronaut, Air Force Major Abacha Tunde. He was the first African in space when he made a secret flight to the Salyut 6 space station in 1979. He was on a later Soviet spaceflight, Soyuz T-16Z to the secret Soviet military space station Salyut 8T in 1989. He was stranded there in 1990 when the Soviet Union was dissolved. His other Soviet crew members returned to earth on the Soyuz T-16Z, but his place was taken up by return cargo. There have been occasional Progrez supply flights to keep him going since that time. He is in good humor, but wants to come home.

In the 14-years since he has been on the station, he has accumulated flight pay and interest amounting to almost $ 15,000,000 American Dollars. This is held in a trust at the Lagos National Savings and Trust Association. If we can obtain access to this money, we can place a down payment with the Russian Space Authorities for a Soyuz return flight to bring him back to Earth. I am told this will cost $ 3,000,000 American Dollars. In order to access the his trust fund we need your assistance."

The Kitty Convict Project

Ladies and gentlemen, the exploding kittens team present you an incredibly practical solution to mark your indoor cat: Orange bracelets, named the kitty convict project.

The idea is simple but genius: If you have an indoor cat, put an orange collar on it, so others know that it is escaped.

kkp_printable_largeIts kind of fun, still the idea is simple and practical - And it makes totally sense. Share the idea, if you like it! Share links are on the convict kitty projects page 🙂

Perseid Meteor Shower

On a nice, cloudless night in Mid-August one can observe a beautiful spectacle of nature: The Perseid showers.

Perseid Shower - Creadit APOD
Perseid Shower over Mount Shasta - Creadit APOD

According to Bill Cooke from NASA this year will be exceptional good, where normal rates are somewhere between 50-75 meteors per minute, this year we could have peaks up to 150 and even 200 meteors per minute.

The meteors appear to originate from the constellation Perseus, giving the shower it's name.  In reality the meteor comes from a debris field, left behind of 109P/Comet Swift-Tuttle. The comet was already known by the Chinese in 188.
The shower can be seen as Shooting Stars, leaving a small trail of ionized gas behind them.

During the whole travel through the debris field in July and August one can see the Perseid shower, but in the range from 12. - 13. August there will be a maximum. The peak is expected on 12. August between 13:00 and 15:00 UTC.

For HAM-operators this peak is interesting. Because of the increase ionisation of the Ionosphere, sporadic-E-Emission are way more likely to happen. Also long echoes in the 2m band are possible during the Perseid shower.

Cortana becomes a Must-Have

Good news for Windows 10 users:

You won't be able to turn off Cortana once the next obligatory update comes out.

Yes, Microsoft has decided for you, that Cortana is so awesome, that you should never ever just think on turning that stupid thing off.

I really hope that Steam OS takes over the games market, so I can finally get rid of Windows for good. That's anyway the last use case where I'm still stuck on Windows sometimes.
Oh by the way: Just as a random conspiracy theory because it fits so well here: Microsoft wants to make Steam buggy and broken, so Users switch to the (also buggy and even more broken) Windows Store.

I'm really looking forward to the release of ReactOS.

Stay in touch. Once it is official and I find a way to get rid of this feature I'll tell you how you can also do this [and here it is].

And as a short reminder: W4RH4WK wrote a set of Windows 10 Debloater PowerShell scripts.

A quote for peace

In respect to the turbulence and all the violence we are currently facing, I want to quote one of the most famous and inspiring personalities of our time

The planet does not need more ‘successful people’. The planet desperately needs more peacemakers, healers, restorers, storytellers and lovers of all kinds. It needs people to live well in their places. It needs people with moral courage willing to join the struggle to make the world habitable and humane and these qualities have little to do with success as our culture is the set.

Tenzin Gyatso, The 14th Dalai Lama, Via

Don't get lost in the maelstorm of hate, enviousness and distrust. Peace, freedom and humanity are the virtues, that the world needs in this times.
