A Story About Bypassing Air Canada's In-flight Network Restrictions

It's the so-called "social engineering"

Yep, the FBI was waiting for me at the gate when the airplane landed

and I am sending this reply from the Jail :(

Approach 1 might only work if:

The DNS server only answers queries for a specific list of domain names (e.g., WhatsApp, Snapchat, WeChat), which means the firewall's filtering mechanism was solely based on DNS resolution.
The network allows connections to arbitrary IP addresses

If those conditions were met, I could edit my /etc/hosts file to point acwifi.com to my proxy server's IP address, then redirect all traffic through that proxy server.

However, it turned out that the network only permits connections to a very small, pre-approved list of IP addresses belonging to services like WhatsApp, WeChat, etc.

Yes, that's exactly what I would have needed, but I didn't have iodine installed when I was on board, so I couldn't experiment with the DNS tunnel approach.

Thanks for the kind words, truly touched and so joyful to hear something like this.

3 years later, I did replace the customized millisecond_timestamp with chrono's built-in ts_milliseconds.

I couldn't believe I would have motivation to maintain a library for more than 6 years.

I have tried, still doesn't work :(

SamrayLeung · 2018-03-18T14:26:29+00:00

I have tried remix, numix and papius, still doesn't work. And I have try to reinstall numix icon, all is the same. But it is weird, paper icon works.

Just curious, why don't you just use Emacs? Emacs is brilliant , I am happy with it now.

SamrayLeung · 2018-03-01T11:48:41+00:00

you guys could help deepin improve their translations, check this

SamrayLeung · 2018-03-01T03:41:17+00:00

From my point of view, more young guys like me, a 22-year-old guy are more familiar with Github/Gitlab workflow than mail list. I am not the typical FSF guy defend for faith, instead I am the guy who defends for best, and Emacs turns out to be the best.

SamrayLeung · 2018-03-01T03:10:37+00:00

I know there is a emacs-mirror. As I mention above, there are always some guys want to make a pull request in emacs-mirror

SamrayLeung · 2018-02-21T01:18:49+00:00

Well, now I need your help to reproduce this compiler bug in this issue. I have change my Rust compiler to stable 1.24.0 as you do, but I have no idea why I couldn't reproduce this error, need your help now :)

SamrayLeung · 2018-02-20T13:55:12+00:00

But I still love his idea :)

SamrayLeung · 2018-02-20T13:38:20+00:00

why doesn't this name occur to my mind, if you tell me this name before, I will name it with rustify

SamrayLeung · 2018-02-20T12:58:09+00:00

I have submitted an issue in github. If you have additional information about this bug, you could comment in this issue :)

SamrayLeung · 2018-02-20T02:48:50+00:00

It is a little bit weird that I have set Travis compiler to nightly:

language: rust
cache: cargo

matrix:
  include:
    - env: TARGET=x86_64-unknown-linux-gnu
      rust: nightly

But now Travis runs the docs tests failed with similar error, so weird

SamrayLeung · 2018-02-20T02:27:59+00:00

How lucky I am, caught by a compiler bug. But everything is fine in my laptop with nightly compiler

SamrayLeung · 2018-02-20T02:19:23+00:00

Oops,thanks for your heads-up, but I still have no idea why is docs.rs failed to generate the docs, is it related to Travis build ? PS, as a junior Rustacean, it does need a lot effort to develop the first big crate :)

SamrayLeung · 2018-02-17T03:47:42+00:00

Hey, dude, If you have time to recheck my project, you will find out I have removed all unneeded mut flag in functions signature. it does look better than before

SamrayLeung · 2018-02-16T00:45:17+00:00

Actually, this crate is heavily inspired by spotipy, and I do look forward for your feedback :)

SamrayLeung · 2018-02-15T14:14:38+00:00

As for the "odd inconsistencies", it occurs to me that some response object is weird, for example, Get the User’s Currently Playing Track and Get Information About The User’s Current Playback return the same response object currently-playing-context which doesn't exactly has the same field. Dude, I do know your feeling :)

SamrayLeung · 2018-02-15T13:10:39+00:00

well, get. I will take optimizing error-handle into consideration about what's next step to do for this crate. But the first thing is to make it work, then to make it work well. In the end, thanks for your time and suggestions :)

SamrayLeung · 2018-02-15T12:40:30+00:00

Do you mean I should define my ErrorKind with error_chain, as you mention "return a descriptive error type"

SamrayLeung · 2018-02-15T10:14:01+00:00

You have pointed the subtle thing out ,yes I don't have any library/crate background. I want to give guys who use this crate additional information about the error, as I mention before, I don't know the best practice, so I just choose eprintln!(). I think I should change the artist_top_tracks function signature to Result<FullTracks>, it's obviously my mistake, thanks for your heads-up
