The Essen Hackathon 2015 starts. More or less around 6pm people started to show up (including myself). The socializing session (BBQ) had some funny/interesting stories, and provided already some interesting topics to have a closer look at.
Possible candidates where I can provide some input are around DTrace: How to use it (but probably Sean Chittenden has some much more interesting DTrace things to show) and how to add SDT probes to the kernel.
On the ports side I want to get some insight into the USES framework, to see if it may be easy to convert the linuxulator ports to it or not. Maybe I can also have a deeper look into patches for the 64bit side of the linux_base ports.
I (still) use a Nexus S phone. I am using Cyanogenmod on it. After an article in a computer magazine I decided to give the ART-runtime a try instead of the default Dalvic-runtime. Unfortunately I do not have enough free space free (and all what I can is moved to the USB storage already) to really use the ART-runtime.
After switching back to the Dalvic-runtime, I had only 2⁄3 of the previously available space free. After a little bit of looking around I found /data/dalvik-cache. I deleted with a file manager the content of the directory (you will get some “app crashed/died” messages) and rebooted the phone (this is not the same as formatting the cache partition in the recovery system).
During boot it populated the directory again and now I have more than 4⁄3 of free space on the internal storage.
Maybe not all… my colleagues wouldn’t have gone there if I wouldn’t have said something…
To be honest, I would have expected something a little bit more shiny/geeky/… to take a picture of (anyway, if you don’t see it: I have a real smile in my face on the picture, so the geek in me enjoyed taking the photo).
In case you use a Browser which “is registered with Google” (cookie, Chrome sync, Hangouts plugin …) in a way that Google knows who you are when you enter the search page, and you have your birthday entered in this account, then Google presents you a “Happy Birthday” Google-Doodle on that day. If you are not on Google+ and you klick on the picture, you get a page which offers you to upgrade to Goolge+.
Funny/scary? Up to you. For me it just visualises what I knew already (you can do a lot with personal info, and Google get’s a lot of this) and I say “Thank you Google” (but I don’t upgrade to Google+).
