That is *exactly* the magic of objects - hiding ugly implementation details
(like shell scripts) under an abstraction you can easily understand and dare
say enjoy working with!

Great! Looking forward to it. This is a great time to share even toy
projects because GitHub et al have made the effort/pain/cost so low.

Hi All,

Sorry for the late answer, I've been swallowed by a vortex of "too much
work at my day job".

Regarding the magical power of smalltalk, I definitely agree with that.
I've been playing with different programming languages for 30 years now,
and smalltalk programming is so refreshing, it's almost like manipulating
real physical objects, the process of building an app feels way more
creative this way.

Regarding my quick hack for managing the wifi at home, unfortunately there
is not so much smalltalk magic involved. Pharo is just used as a UI to
launch shell scripts on a linux server. This server is inbetween a wifi
access point and the ISP router. So, as you probably have guessed, all the
wifi traffic goes trough this server, then it's easy to use the linux
firewall (iptable) to allow/deny traffic.

I'll continue playing/hacking on this small app and I'll publish the end
result.

Thanks All,
Daniel

Quick hacks are still often interesting reading and useful starting
points for others.
I've often thought of doing something like this for my kids but never
got around to it.

> but I already can stop the wifi from my phone

I'm interested to know what you use for that also.

once you are done please share it.
You see I'm good in deep little details but I often lack other knowledge :)

Thanks Stef, this app is just a quick hack but I already can stop the wifi
from my phone and I feel like I have new negociations superpowers...

Thanks Hernán ! That's a perfect fit :)

Welcome daniel

This sounds like a super cool app. (I have teens at home and well I
know the story).

I remember a calendar triggering system but I do not know where it
is. Someone should know.

[Pharo-users] execute a code block at a given time in pharo ?

[Daniel BLANC]

Hi All,

I'm a very beginner with smalltalk. I am building a small seaside app for
controlling wifi access of my teenagers kids. In this app I need to start
or stop the wifi acces at a given time.
For the moment I'm doing it with an infinite loop in a process, with this
code:

WifiController >> startScheduler
^ SchedulerProcess
ifNil: [ SchedulerProcess := [ [ true ]
whileTrue: [ self schedulerApplyAutoStartStopRules.
56 seconds wait ] ] forkNamed: 'DanWifiManagerScheduler' ]


 I'm wondering if there is a way to do this without this infinite loop ?
May be there is a class in the standard pharo image that can execute a code
block at a given time ?

Thanks,
Daniel
