  • ⁸I don’t know what data they have at hand to work with, the following is mainly guesswork / how I would do it:

    As far as I know, US authorities have quite liberal access to data stored by US companies (due to the cloud act even if the data isn’t originally stored in the US), especially in case the data is about non-citizens where some of their protection laws don’t hold. Most social media accounts are tied to phone numbers and/or email addresses.

    If I was in their place, I’d have a relatively small database with all (or at least all non-US) phone numbers used for social media accounts, with the email addresses tied to those accounts. If a visa-applicant applies and I get their phone number (email address),

    1. I’d query a list of all accounts for that number (email) to get the associated emails (numbers).
    2. With those new emails (numbers) I’d repeat step 1

    If you call the office or enter your number in your application, they might get some accounts. If you associated an email address to that account, they might get additional different accounts by that email. If those different accounts have a different phone number associated to them, they use that new phone number to get more accounts. rinse, repeat.

    [Edit: This process would be completely automated, of course. Not manual.]

    The consequence of being caught lying might be to get your visa revoked / denied once you are already in the US at the airport, which would be highly inconvenient. Or, if they get suspicious, find something else, and get annoyed, maybe it could even be punished? I don’t know.

    You could maintain a separate phone with a separate phone number and separate email addresses for accounts you want to keep secret. Or maybe get a fresh phone number / email address just for the trip. But that’s quite a bit of effort to maintain consistently.











  • Controversial opinion of an atheist:

    Most religion is incitement to hate-crimes. While I think Sweden has probably bigger Christian societies and should probably rather burn bibles, the guy burning the Quran is an Iraqi, and therefore choosing the Quran is understandable. Afaik, he protested against his own former repression by Muslim religion whe still lived in Iraq.

    Religion is notoriously used to reduce other people’s freedom. Be it fundamental Christians e.g. in the US or Poland denying healthcare to pregnant women, be it the atrocities committed by the “moral police” in Iran, be it other religions killing people for their sexuality. I support the idea that religious law should be limited to followers of that religion, and no person should be forced in any way to follow or keeps following any religion. Those are fundamental human rights principles in my eyes.





  • Currently kinda controversial, but currently it’s still Fedora, the xfce4 version.

    I had Debian for some time before, but had my apt packages messed up a couple of times to the point I had to entirely re-install. In stable, I was missing sufficiently recent versions, in testing I had other problems.

    With Fedora dnf I had less problems recovering, usually more recent versions.

    Xfce4 is just more suitable for my needs than Gnome.


  • I sometimes use openstreetmap, and it has its strengths and weaknesses. The data is afaik usually collected by GPS trackers and uploaded, therefore usually less accurate than some of the commercial providers using LIDAR etc. to actually measure the roads. Also, streets are missing speed limit information etc. And I don’t think they invested as much effort in data density, making the data cost prohibitive to download maps of e.g. multiple countries.

    On the other hand, OSM is

    • free. As in freedom, free license, etc. You can take screenshots and use them without being too woried about the license.
    • If you want to integrate it in your website to e.g. allow tracking of items etc., I don’t know if the API is rate-limited, but if you wanted, you could actually download the relevant map data and host everything yourself.
    • Hiking trails are often more complete and helpful

    Regarding Google, Apple and Bing maps:

    AFAIK, Apple and Bing are using mainly TomTom, they don’t have their own map data (I think Apple started collecting their own via GPS from navigation apps etc.). I think the only significant companies actually owning gobal map data are Google, HERE Technologies and TomTom.
