This AA Battery Sucks Power Right Out of the Air (

[…] is that the transmitter broadcasts a directed and concentrated RF signal towards a given device in a room, which is absorbed by the gadget’s own RF antennas inside, and turned into usable power.

Woah! That’s some quite interesting piece of technology!

Light Traffic (

Traffic lights are a 150-year-old technology originally conceived for horse carriages. Will they survive the advent of autonomous vehicles?

Very interesting approach that asks if the intersections with traffic lights might be a thing of the past as soon as a lot of vehicles will be autonomous.

The Brutal Lifecycle of JavaScript Frameworks (

JavaScript UI frameworks and libraries work in cycles. Every six months or so, a new one pops up, claiming that it has revolutionized UI development. Thousands of developers adopt it into their new projects, blog posts are written, Stack Overflow questions are asked and answered, and then a newer (and even more revolutionary) framework pops up to usurp the throne.

Interesting Data on the rise and fall of JS Frameworks

DNSFS. Store your files in others DNS resolver caches (

[…] and I joked at the end that one could use this for file storage.

Well, I could not stop thinking about doing this. There are surely a lot of open DNS resolvers out on the internet, that are just asking to be used for storing random things in them. Think of it. Possibly tens of gigabytes of cache space that could be used!

After PingFS comes DnsFS!

GoPro quits the drone business (

GoPro has announced that it’s exiting the drone business, citing the challenges of turning a profit in an “extremely competitive” market.

Boom – GoPro is out of the Drone business. What initially was deemed to save the entire company just has been stopped.

flowerhack | The Internet I Knew (

We… we had ad-free social networking in 2004. It was called “one of your friends got a Dreamhost and put some forum software on it and everyone hung out there.” If the website got really big and popular, maybe the owner would ask for donations from the users, and usually folks would give enough to keep the place afloat, because everyone wanted to keep hanging out there.

Hi Friend,

da wären wir wieder mal. Ich weiss Beharrlichkeit ist nicht gerade, was mich hier auszeichnet, jedoch haben mir in den letzten Wochen einige Leute gesagt, dass sie diese Blogposts gerne lesen.

Da die letzten Tage ein wenig ruhiger waren, hab ich mal wieder ein paar Links zusammengesammelt. Zwischen Bitcoin, Security und einigen guten Longreads findet sich hier einiges.

Why an eight-hour bus ride from Los Angeles to San Francisco might beat a flight (

Cabin is an interesting experiment; an attempt to compete with airlines by promising a better night’s sleep. Flying between the two cities may take less than an hour and a half. But getting to the airport, shuffling through the security queue, waiting at the gate, picking up your bag upon arrival, and getting from the airport to your actual destination can nearly quadruple the total travel time. That means a trip can eat up most of the day. Or if you want to travel at night, you have about an hour to sleep, between several hours of hassle and tedium.

That’s among the reasons, why I prefer the night train to wherever place possible in europe 🙂

bloomberg/powerfulseal: A powerful testing tool for Kubernetes clusters. (

PowerfulSeal adds chaos to your Kubernetes clusters, so that you can detect problems in your systems as early as possible. It kills targeted pods and takes VMs up and down.

Edward Snowden’s New App Uses Your Smartphone to Physically Guard Your Laptop (

Here’s how Haven might work: You lock your laptop in a hotel safe — not a secure move on its own — and place your Haven phone on top of it. If someone opens the safe while you’re away, the phone’s light meter might detect a change in lighting, its microphone might hear the safe open (and even the attacker speak), its accelerometer might detect motion if the attacker moves the laptop, and its camera might even capture a snapshot of the attacker’s face. The Haven app will log all of this evidence locally on the Android device.

It’s still in early beta state but I like what it does so far.

Learning to operate Kubernetes reliably (

We recently built a distributed cron job scheduling system on top of Kubernetes, an exciting new platform for container orchestration. Kubernetes is very popular right now and makes a lot of exciting promises: one of the most exciting is that engineers don’t need to know or care what machines their applications run on.

Distributed systems are really hard, and managing services on distributed systems is one of the hardest problems operations teams face. Breaking in new software in production and learning how to operate it reliably is something we take very seriously. As an example of why learning to operate Kubernetes is important (and why it’s hard!), here’s a fantastic postmortem of a one-hour outage caused by a bug in Kubernetes.

Internet Chemotherapy (

There will also be those who will criticize me and say that I’ve acted
irresponsibly, but that’s completely missing the point. The real point
is that if somebody like me with no previous hacking background was able
to do what I did, then somebody better than me could’ve done far worse
things to the Internet in 2017. I’m not the problem and I’m not here to
play by anyone’s contrived rules. I’m only the messenger. The sooner you
realize this the better.

Homeland Security team remotely hacked a Boeing 757 (

“We got the airplane on Sept. 19, 2016. Two days later, I was successful in accomplishing a remote, non-cooperative, penetration,” Hickey said in an article in Avionics Today. “[That] means I didn’t have anybody touching the airplane; I didn’t have an insider threat. I stood off using typical stuff that could get through security, and we were able to establish a presence on the systems of the aircraft.”

No Justification for Spanish Internet Censorship During Catalonian Referendum (

With an extremely narrow range of exceptions, government censorship of the Internet is prohibited by Article 19 of the Universal Declaration of Human Rights, and by Article 10 of the European Convention on Human Rights, both of which guarantee everyone’s right to receive and impart information and ideas regardless of frontiers. The Spanish government’s censorship of online speech during the Catalonian referendum period is so wildly disproportionate and overbroad, that its violation of these instruments seems almost beyond dispute.

Keine Regierung sollte ihren Bürgern jemals vorschreiben was sie im Internet anzusurfen haben. Geschweige denn Seiten in diesem Masse sperren – Basta!

Bluetooth won’t replace the headphone jack (

To improve Bluetooth, platform vendors like Apple and Google are riffing on top of it, and that means they’re building custom solutions. And building custom solutions means they’re taking the opportunity to prioritize their own products, because that is a fair and rational thing for platform vendors to do.


The playbook is simple: last year, Apple dropped the headphone jack and replaced it with its W1 system, which is basically a custom controller chip and software management layer for Bluetooth. The exemplary set of W1 headphones is, of course, AirPods, but Apple also owns Beats, and there are a few sets of W1 Beats headphones available as well. You can still use regular Bluetooth headphones with an iPhone, and you can use AirPods as regular Bluetooth headphones, but the combination iPhone / W1 experience is obviously superior to anything else on the market. No one else can make W1 headphones, and obviously no one else can modify iOS to support their own custom wireless Bluetooth riff. So your choices are the four W1 headphones, and then a large market of second-class citizens.

Nicht das Google das unglaublich viel offener Machen würde. Aber der Trend ist eine DRMifizierung von sämtlichen Datenwegen. Gefällt der Musikindustrie und den Premium-Hardware-Herstellern bestimmt 😉

Aish Raj Dahal – Chaos management during a major incident (

No software system on the planet is today fully failure-resistant. Given this, it becomes crucial for software teams to be able to deal with major production incidents in a nimble way. However, just as complex systems fail, responding to a major system outage is a painful operational exercise that may at times require multiple stakeholders to work together. In this talk, Aish discusses how to efficiently deal with the human element, when complex systems fail.

Good talk on chaos management during an incident

Do you want a black rectangle or a white one? A slightly bigger rectangle or a thinner rectangle? The rectangle with a camera bump or without it?

this is so true 😉

When was the last time you bought a new laptop? Chances are you’re reading this on something you bought four or five years ago. The same is happening to phones right now and the iPhone X is likely the last device that will matter in the category.

As “Phones” (read PocketDatacenters) become vastly powerful the need of getting a new one every year drops.

The Pixel’s missing headphone jack proves Apple was right (

Apple’s bet in removing the headphone jack was that we could stomach some short-term inconvenience for the longer-term benefits of freeing up valuable real estate inside the phone. It was a calculated risk, intended in part to also force the development of better wireless and digital gear by headphone makers.

Sadly Bluetooth microphone quality still sucks 😉

The Ridiculous Amount of Energy It Takes to Run Bitcoin (

It uses an absolutely stunning amount of power. The ever-expanding racks of processors used by miners already consume as much electricity as a small city. It’s a problem that experts say is bad and getting worse.

90,000 Guns But No Gun-Related Crimes (

“My dad had guns and hunted. So guns were always around when I was a boy,” says gun owner and hunting enthusiast Árni Leósson. “When I got older I got really into fly-fishing and from there I got interested in hunting but to do that I had to get my own guns. It was just pragmatism and I think the reason gun crime is so alien in Iceland is the ‘gun culture.’ In Iceland guns are for practical things like hunting and not for protection. We have the police for that.”

Let’s talk about guns. Example: Iceland

How Microsoft become a destination for a new generation of open-source developers (

The new developer advocate role at Microsoft appears to be less about forcing Microsoft technology down people’s throats and more about meeting them where they are, identifying promising open-source cloud projects and helping out in whatever capacity makes the most sense. Sure, the goal is to still convince them that Azure is the best place for their workloads, but more in the sense of understanding what cutting-edge developers want and working to provide those services in Azure.

Way to go Microsoft!

Why working from home should be standard practice (

One or two days a week is probably the ideal amount of time to work from home, suggests Bloom. “You don’t want to go much higher because you risk jeopardizing the cohesion of your team.” As companies compete to hire and retain the best employees, being able to offer the option to work from home can sweeten the deal. “The need to go into a workplace five days a week started because people had to go to a factory and make products,” he says. “But companies that still treat employees like that are increasingly finding themselves at a disadvantage.”

Keep Calm and Carry On – Scaling Your Org with Microservices (

Ask people about their experience rolling out microservices, and one theme dominates: engineering is the easy part, people are super hard! Everybody knows about Conway’s Law, everybody knows they need to make changes to their organization to support a different product model, but what are those changes? How do you know if you’re succeeding or failing, if people are struggling and miserable or just experiencing the discomfort of learning new skills? We’ll talk through real stories of pain and grief as people modernize their team and their stack.

Fantastic talk from two of my favourite speakers!

When it comes to internet privacy, be very afraid, analyst suggests (

SCHNEIER: Snowden’s revelations made people aware of what was happening, but little changed as a result. The USA Freedom Act resulted in some minor changes in one particular government data-collection program. The NSA’s data collection hasn’t changed; the laws limiting what the NSA can do haven’t changed; the technology that permits them to do it hasn’t changed. It’s pretty much the same.

Bruce Schneiers Aussagen sprechen Bände.

The Land of Many Captchas (

There are certain things I cannot do over Tor, either due to my mistrust in exit nodes or by being blocked by certain services. A VPN could be used to evade Tor bans, but those present other potential issues (and I still don’t trust them for extremely sensitive tasks).

If you can live with captchas, annoying as they are, 95% of the captcha’d world can be accessed. The 5% is to account for when sites place their CSS/JS assets behind CloudFlare without whitelisting Tor.

I think I’ll extend this experiment by one more week. Chances are, I’ll keep extending indefinitely.

  6. Use a prepaid, disposable phone
  7. Back up your data
  8. Consider biking or walking to the protest
  9. Enable airplane mode
