Quick conference review: both 44con and ekoparty were great. Ekoparty was especially awesome since I got to check the last continent off my list. Also the size of ekoparty was way beyond what I was expecting. They managed to have a really good conference that is professionally run while stilling maintaining the vibe of a hacker / underground con <3

Two weeks ago there was a post on Medium about two companies that provide a mobile identification service. That service basically can be used to convert your phone's IP address into real information about the owner of the phone (the contract owner). This is done via APIs that are provided by multiple Mobile Network Operators (such as AT&T). The medium article linked to demo pages of those two service providers (payfone and danal inc) that show not only your phone number but also your operator's name, your name and address.

I played with the two demo sites for a bit (while they were still online - offline now). I'm on Google Fi with a number proted from T-Mobile (pre-paid). Payfone only had my phonenumber and old carrier (T-Mobile) while Danal inc showed no data at all. I never provided any data to T-Mobile since it is not required for a pre-paid card. Google has all the data but likely does not share it with 3rd parties.

Overall this is a service that I really don't want to exist. I don't want an abritary company to be able to identify me while visiting their website from my mobile phone. I hope those companies don't just sell their services to anybody. Read the Medium article again: AT&T consumer choice opt-out doesn't affect this!

iOS 11 the tragedy continues: 11.0 had a bunch of flaws that were annyoing. Now 11.0.3 randomly frezzes my phone for minutes. Also I have some issues with voice call audio not working sometimes. Highly disaspointing!
