How did you get your phones display on your desktop?
- snehesht 10y ago
  I'm not the author but If I have to guess, author must have recorded the phone screen ( using something similar to https://play.google.com/store/apps/details?id=com.hecorat.screenrecorder.free https://play.google.com/store/apps/details?id=com.hecorat.sc... ) and desktop screen, overlapped the phone screen video onto the desktop using video overlay feature during post production.

    Could have also possibly been an emulator.

  You can use adb to screenrecord. (I have never tried it though) https://developer.android.com/studio/command-line/shell.html https://developer.android.com/studio/command-line/shell.html EDIT: I think this actually does not answer your question. Sorry.

    You can use Vysor which mirrors android screen on desktop. https://chrome.google.com/webstore/detail/vysor/gidgenkbbabolejbgbpnhbimgjbffefm?hl=en-US https://chrome.google.com/webstore/detail/vysor/gidgenkbbabo...

  Are you sure that's his phone and not Android Studio's Android Emulator (https://developer.android.com/studio/run/emulator.html https://developer.android.com/studio/run/emulator.html)?
  - dschep 10y ago
    That was my Nexus 5x. The computer was a VM tho.
- dschep 10y ago
  I didn't. Recorded videos on both the phone and the computer(a VM actually), then put it together with.. I don't remember what. Some video editor available in the Ubuntu repos.

Neat, I've been working on a similar tool, but I've been trying to make it not require a 3rd party service for cross machine notifications. I've been testing things out like udp multicast and zyre. mobile notifications are tricky, looks like one can use https://developers.google.com/web/updates/2015/03/push-notifications-on-the-open-web https://developers.google.com/web/updates/2015/03/push-notif..., but that still technically piggybacks over google cloud messaging.

  The problem I have with that is I then have to run yet another app on my phone. I want to run less apps, not more (especially on Android, where running an app seems to mean it can use any amount of battery it wants). When my subscription to PushBullet runs out I'll be experimenting with PushOver. It's Growl all over again, but not quite as good. Edit: Ntfy looks like exactly what I want. I do really like the idea of notifications that stay within my LAN, or are under my direct control. Now that I have SSL on my home server, I should be able to use Chrome notifications to Android (but isn't GCM involved there somewhere anyway?)

  It adds another dependency, but you could always try Avahi/Zeroconf. Good for service discovery on a local network.

  I ran into this the other day but had trouble getting the server to run: https://f-droid.org/repository/browse/?fdfilter=notification&fdid=org.androidpn.client https://f-droid.org/repository/browse/?fdfilter=notification...

I was hoping to see a framework for getting notifications in the shell, like in the screen / tmux status bar.
- snehesht 10y ago
  You could try a script that receives notifications and then prints them inside the status bar. Tmux has refresh interval so you could easily setup a script that prints the notification for a while and then clears it. set -g status-right "#[fg=colour010]#(/path/to/your/script)#[fg=colour255]"
- qznc 10y ago
  You could use "wall", but that is not limited to a status bar and just prints in the terminal.
- dapithor 10y ago
  You can already do this with `write` which is in most linux distro's. Make sure `mesg` is set to y then test with `echo "hello" | write <username>`. `Wall` messages all logged in users and I wouldn't recommend that approach.

This already exists. It's called noti. It's cross-platform, supports most of the same backends, and can send Slack notifications (which ntfy can't). It also has an awesome API. You can put `noti` at the start of a command or `;noti` at the end, which is what I always do. I never remember to set the notification until after I've typed the command. If you forget to set the notification and the command is already running, you can call `noti -pwatch <pid>` and set notifications after the fact. It's very well thought out. https://github.com/variadico/noti https://github.com/variadico/noti

  Apart the fact that you sound like an advertisement for another software it takes just a few seconds to see that noti doesn't work on windows or with telegram for example. Not supporting a major OS is a big deal.
  - dmos62 10y ago
    Only if you are using that major platform.
    - buster 10y ago
      I don't use Windows, but Linux.
  - voltagex_ 10y ago
    I'm adding very basic Windows 10 (because notifications are ~50 lines there, many many more on older platforms) support. Writing my first Go code was easier than packaging ntfy for Windows, FWIW.

    Telegram is dangerous snake oil, and its use should be discouraged.
heydonovan 10y ago
I've always just used mail to send a text for notification: ./long_running_script.sh && mail -s "Script Done!" number@tmomail.net
posixpwn 10y ago
The fact that it doesn't support major OS is a bummer
- dschep 10y ago
  How so? It runs on Mac OS, Linux and Windows.
tymm 10y ago
Funny to see this on HN since I just released an Android App called Simplepush (https://simplepush.io https://simplepush.io) which qualifies for what Ntfy calls a backend. Let's see if they accept a PR to list me as an additional backend :)
- dschep 10y ago
  Yup! I'll review it when I'm not sleepy :)

I am looking for a tool that sends me webhooks for events that happen on my phone. (Idea is to pre-process SMS message that I get and show me priority notifications via Chrome or other means). Anyone knows of something that does this? (Android)
- tymm 10y ago
  I think pushbullet does that.
mxuribe 10y ago
Seems pretty cool!
dtjohnnymonkey 10y ago
On OS X I usually do 'cmd && say "files done" || say error'
