Dinner time


Yesterday I noticed some Jackdaws were eating the food that was meant for the smaller birds like Great Tit and Redbreast (European Robin). With my camera it wasn’t possible to take a picture, as soon as I moved they flew off. Today I installed an old webcam (640×480) and controll it from my computer.
Webcam : Logitech QuickCam Express V-UBC40

The Canary in the Coal Mine / De kanarie in de Kolenmijn

My latest ebook, it’s a warning by Marianne Thieme and Ewald Engelen against the unsustainability of the current political and financial choices.

Synopsis

Ewald Engelen and Marianne Thieme warn against the unsustainability of today’s politics and financial choices. Like a canary in a coal mine, they identify the dangers that jeopardise our future. Such as the fossil perspective, which has led to the near-complete depletion of the collected reserves of fossil fuels. Or the fact that famine is not the result of insufficient food production, but predominantly due to food distribution and waste issues. And that conflicts over water are not a thing of the distant future, but are already manifest in the present. The majority of politicians and scientists opt for marginal changes within the status quo, focused on more economic growth and increased free trade. Ewald Engelen and Marianne Thieme advocate a radical change of direction. Engelen from an economic perspective, Thieme from an ecological standpoint. They reach a common conclusion: the financial system and the political structure are rotten to the core. Plan B is unavoidable. Ewald Engelen (1963) is professor of financial geography at the University of Amsterdam, where he studies the global financial system. As a publicist and activist, he is well-known for his criticism of the euro and TTIP, the trade agreement between the United States and the European Union. Marianne Thieme (1972) is group leader for the Party for the Animals (Partij voor de Dieren) in the House of Representatives in the Netherlands, lawyer, animal rights and environmental activist and publicist. In 2002 she was one of the co-founders of Party for the Animals (Partij voor de Dieren).

Conversations XMPP client

Finally I found a messenger that I really like : Conversations, it uses the XMMP (formerly known as Jabber) protocol. It has not only encryption but it respects my privacy, I don’t need a phone number or e-mail adress to register an account at a XMPP server*. Encryption is done by OMEO, OTR (Off The Record) or OpenPGP.

Conversations is an Android app, you can download it in the PlayStore, but then you have to pay. If you install the F-droid app on your Android device you can download it legally for free
You can find more clients here

* Signal and WhatsApp have good encryption, but you need your phone number to register AND you have to give your number to people otherwise they can’t call or send you messages. An other problem of WhatsApp is the spying by Facebook.
Telegram needs a phonenumber to register, but you can use a nickname so your number stays private.
Wire don’t need a phonenumber, it uses only a nickname.

Martin Luther King Jr. Day

Today it’s Martin Luther King Jr. Day, every 3rd monday of January we are commemorating the birth of Martin Luther King Jr.
He was born on January 15 1929 and shot on April 4 1968.

King was a non violent activist and leader in the Civil Rights Movement.

His famous words “I Have a Dream” from his speech during the March on Washington for Jobs and Freedom on August 28, 1963 :

I say to you today, my friends, so even though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream.
I have a dream that one day this nation will rise up and live out the true meaning of its creed: ‘We hold these truths to be self-evident: that all men are created equal.’
I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood.
I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice.
I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.
I have a dream today.
I have a dream that one day, down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of interposition and nullification; one day right there in Alabama, little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers.
I have a dream today.

WhatsApp, safe or not

The Guardian published an article about a vulnerability that allows snooping on encrypted messages.

Facebook claims that no one can intercept WhatsApp messages, not even the company and its staff, ensuring privacy for its billion-plus users. But new research shows that the company could in fact read messages due to the way WhatsApp has implemented its end-to-end encryption protocol.

The security loophole was discovered by Tobias Boelter, a cryptography and security researcher at the University of California, Berkeley. He told the Guardian: “If WhatsApp is asked by a government agency to disclose its messaging records, it can effectively grant access due to the change in keys.”

The vulnerability is not inherent to the Signal protocol. Open Whisper Systems’ messaging app, Signal, the app used and recommended by whistleblower Edward Snowden, does not suffer from the same vulnerability. If a recipient changes the security key while offline, for instance, a sent message will fail to be delivered and the sender will be notified of the change in security keys without automatically resending the message.

Comments from Open Whisper Systems :

Background

Today, the Guardian published a story falsely claiming that WhatsApp’s end to end encryption contains a “backdoor.”

WhatsApp’s encryption uses Signal Protocol, as detailed in their technical whitepaper. In systems that deploy Signal Protocol, each client is cryptographically identified by a key pair composed of a public key and a private key. The public key is advertised publicly, through the server, while the private key remains private on the user’s device.

This identity key pair is bound into the encrypted channel that’s established between two parties when they exchange messages, and is exposed through the “safety number” (aka “security code” in WhatsApp) that participants can check to verify the privacy of their communication.

The issue

One fact of life in real world cryptography is that these keys will change under normal circumstances. Every time someone gets a new device, or even just reinstalls the app, their identity key pair will change. This is something any public key cryptography system has to deal with. WhatsApp gives users the option to be notified when those changes occur.

Resume

It is great that the Guardian thinks privacy is something their readers should be concerned about. However, running a story like this without taking the time to carefully evaluate claims of a “backdoor” will ultimately only hurt their readers. It has the potential to drive them away from a well engineered and carefully considered system to much more dangerous products that make truly false claims. Since the story has been published, we have repeatedly reached out to the author and the editors at the Guardian, but have received no response.

Albeit that WhatsApp is safe, it’s sharing your data with Facebook, so I still recommend Signal and / or Telegram for secure communication.

Resumed Linux support

January 7 I resumed Linux support due to the demand for support because of the End Of Life of Linux Mint 13 LTS, Ubuntu LTS versions 12.04 and Windows Vista.

The service is still free if you come to my place.
I don’t have transportation, so I can only visit you if it’s not to far by public transport, and you pay the expences.

If necessary I can give remote support by mail, messenger service or phone.
