My Bookmarks in June 17

My Bookmarks in June 17

I never really kept a bookmarks list, instead I relied mostly on my ability to find anything important on Google. But about 1-2 months ago I came to reevaluate that behaviour, mostly because of these rare edge cases where it took me a long time to find something I knew I had found once. So I looked for a good chrome extension or service to keep bookmarks.

However I didn’t find anything that really suited my needs. So I cleaned out the good old default chrome bookmarks manager, there were some really old sites in there, and started bookmarking away. Now the default chrome bookmarks manager isn’t bad. It looks a bit dated but on the plus side it’s tightly integrated into chrome and syncs automatically with my other Google settings. The only downside it has is that there’s not way to publish bookmarks or somehow share them socially. So in order to fill that void I’m starting to post my bookmarks list, along with short comments, on my blog every so often.

Installing or renewing a SSL certificate on an Apache server

Installing or renewing a SSL certificate on an Apache server

About a year ago I’ve installed my first SSL certificate for this website. I got that certificate for free from the GitHub Student Developer Pack. So now a year later it’s time to renew it. The renewal process is roughly the same as the registration process so in order to safe myself some time next year I decided to write it up. This isn’t a comprehensive guide, it focuses only on my specific setup. I’m running this site on a digital ocean Ubuntu droplet with Apache2. The SSL certificate is from Comodo RSA, offered through Namecheap.

Live/Video Wallpapers for OS X

Did you know that you can use any screensaver as a animated live wallpaper on OS X? This is how you do it.

  1. Open a new terminal window
  2. Type the following command and press enter:
    /System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background

Once you type crtl-c or close the terminal window the screensaver stops playing.

In order to have a bit more comfortable access to this command I’ve added the following aliases to my .bash_profile file. (.bash_profile can be used to store terminal settings, aliases and custom functions. It is located in your user directory, e.g. /Users/theowinter/.bash_profile and loaded whenever you open a new terminal window.)

Cool “Live Wallpaper” screensavers

  • My favourite live wallpaper is the “Apple TV Aerial” screensaver. It consists of beautiful 1080p video flyovers of cities like New York and London.
  • Another cool screensaver is “SaveHollywood”. You can specify a folder and it will play the videos in there.

There’s probably a ton of other screensavers that might be cool as animated desktop background. So let me know if you find some!

The Expanse: Game of Thrones in Space

The Expanse: Game of Thrones in Space

The Expanse is a gritty, realistic and has a high production value! This is the Sci-Fi series I’ve been waiting for. It plays about two hundred years in the future (I’d say near future), in a partly colonized solar system. Meaning there’s people on earth, Mars and on various space station in the asteroid belt.

Just like in Game of Thrones there’s a large set of main characters in different places and you get to experience the overall story from multiple viewpoints. There’s also beautiful cinematography with gorgeous panning shots, huge vistas and competent use of CGI. But not only the visuals are impressive, the audio design and soundtrack are also top notch. I really hope that they’ll release the music on Google Play once the season is over. It’s also nice that there’s no blatant disregard for physics. For example there’s no “magical” artificial gravity device in the spaceships, instead they use thrust from the engine. So if the ships stops moving forward the gravity stops as well.

So far four episodes have been released and already the series has an IMDB rating of 8.3. And the latest episode “CQB” even achieved a rating of 9.3. Which is really quite impressive.

Information Security

This post is a compilation of various information security questions and topics that are likely to be tested in the InfSi2 exam at HSR. I’m expanding this post step by step while I’m reviewing the contents of this semester. I’ve done something similar with the subject “Automata and languages” last semester and it helped me a lot.
