Recent second canadian citizenship travelling to USA

So i just got my canadian passeport… I used to travel to USA with my tunisian passeport (green passeport with arabic letters) needless to say that i get double checked (second inspection) every single time I go through customs with some weird questions from random agents (they can be cool agents but also rude ones ) … My question is as follows : If the guy asks me if I already got a passeport before my canadian one do I have to answer? Does he have the right to ask me that question? (Btw in order to avoid any issues I might just asks/do whatever he gonna ask me)


Is it still not advisable to use recent versions of EncFS >1.7 to encrypt Dropbox?

I’d like to use EncFS to encrypt files synced with Dropbox. Unfortunately, its Wikipedia page mentions security concerns from an audit of version 1.7:

EncFS is not safe if the adversary has the opportunity to see two or more snapshots of the ciphertext at different times.

Someone with access to my Dropbox account will have exactly that: Dropbox stores multiple previous versions of a file after it’s been modified which is exactly “two or more snapshots of the ciphertext at different times”.

In 2015, this has been confirmed in this question for example: Is ENCFS secure for encrypting Dropbox?

Regarding version 1.8, Wikipedia states:

The announcement of EncFS 1.8 included several underlying design changes, acknowledging the security concerns raised in the previous audit. However, certain concerns still remain regarding those vulnerabilities.

Which concerns do remain? Is the issue regarding Dropbox fixed?

Also, according to the most recent version is 1.9.5, now.

Is it still not advisable to use those recent versions of EncFS to encrypt Dropbox? Does the issue with “two or more snapshots of the ciphertext at different times” still exist?

App switcher to switch to most recent window not working with multiple screens/spaces

First of all, I know that I can do this with a 3rd party app like Contexts. But I would like to do it with the native macOS app switcher.

How to reproduce the “bug”

  • Monitor 1
    • Space 1: Safari (not in fullscreen)
    • Space 2: Xcode window #1 (not in fullscreen)
  • Monitor 2
    • Space 1: Xcode window #2 (not in fullscreen)

You are in monitor 1/space 2, then with CMD-TAB you select Safari, as expected the new active space is monitor 1/space 1. Now you want to go on your last Xcode window, so with CMD-TAB you select Xcode.

  • Current behavior: The new layout is monitor 1 with space 1 and monitor 2 with space 1. The active space is monitor 2 with space 1.
  • Expected behavior: Monitor 1 with space 2 and monitor 2 with space 1. The active space is monitor 1 with space 2.


Is anybody knows why the app switcher does not let me move to the most recent window of Xcode?

Thank you!

Utility of linking to “recent comments” from a blog’s front page?

Quite a few blogs have a section in the right sidebar on the front page which links to the most recent comments, typically citing them by each commenter’s name and the title of the post they commented on.

When I comment on other people’s blogs, I usually return directly to the comments section under an article if I wish to find out whether anyone has replied to my comment. If they replied more than a certain number of comments ago their comment won’t be referenced on the front page anyway.

A cynic would say that the utility of the front-page latest comments section lies mostly in allowing a commenter to feel happy at seeing their name up in lights. But of course that may be exactly the effect that a blog writer seeks. It also kind of shouts out “We get lots of comments traffic, you know”, as if the traffic level were an issue. And if say the latest five comments have all been on the same article, then its title will get shown five times, which doesn’t look nice at all.

On the plus side, visitors can learn from the recent comments section that an old article, or one they haven’t read, is attracting current interest, which might spur them to read it, or at least to read the latest comment on it.
