improve your health by fighting climate change

Congratulations humanity! You are successfully killing yourself! I read on TechCrunch the other day that the CO2 concentration in our atmosphere has climbed to over 415 PPM for the first time in human history. If you look at the graphs on the website it is difficult to dismiss this as not a big deal. If someone out there is still denying climate change after looking at the graphs and taking a note of the timeline…

travel sleeve for travel keebs

Over the past few weeks my GK64 keyboard post has become one of the most popular on my site. Because you gotta ride the wave of fame and because I have an update I decided to write a quick post.

The goal with the GK64 was to have a keyboard in a smaller form-factor that still has dedicated arrow keys because I like them and I do not want to go through getting…

the problem with “the others” and climate change

This post is going to be rather political and the way I will talk about the upcoming issue will not be of good taste to most people. Through my work email I received an email to support an initiative called “Scientists For Future” that concerns itself with climate change. The reason why I post my opinions is because some of my close friends prompted me to sign the statement a few weeks ago already and I…

terakoya @ Tokyo Tech

This week I had the honor to present at a seminar held by professor Suzuki Sakie for her students of mathematics at the Tokyo Institute of Technology. Although my research area is far from her’s (topology), she asked me to present at the seminar. Professor Suzuki called the seminar terakoya which refers to old Japanese temple schools. I introduced usable security and my research road-map very briefly. I finished the presentation with bicycle braking…

expensive rut

We are all made in a way that we get used to the status-quo. In our life we always get used to things. It can be our living situation, our partners, or mundane things as the construction site next to our house. I believe that, while being an important ability of our psyche, it is also dangerous. When we get used to things and accept the current way of life we stop growing. This can even become…

phone security – protect your digital soul

Smartphones are central to our lives. Everyone uses them and they hold every possible piece of information about us. They contain our digital soul and therefore phone security is an important topic. I am regularly shocked at how many people do not use a lock on them. On our phone we have browsing histories, photos, downloads, access to all accounts (mail, social media, banking, etc.), basically our identity. What people often forget is that the phone acts…

gk64 – typing happiness while on the go

This post is not about security or philosophy, which I usually like to write about. If you want to read a post like that I suggest you read my post about password managers. This entry is about hardware, especially the one I use to write these lines. Recently while being abroad I noticed that the quality of my interaction with technology is influenced heavily by my keyboard. For three weeks I only had a rubber dome…

U2F and second factors to get rid of phishing!

This week’s post in minimal security is about second factors. Apart from password managers, this is perhaps something you can apply that increases your security the most. As we have seen inĀ my post about password managers, passwords can be stolen from websites. A universal second factor (U2F) registered with a website will protect your accounts even if your password has been compromised. One other advantage is that it also protects against phishing. Google reported that…
