Modeling Money Units
by Sean P. DeNigris July 21, 2015

July 21, 2015

There are several tools: Aconcagua, Money, Units; and at least two classes to overcome the imprecision of Floats: ScaledDecimal, FixedDecimal... I found one thread where Hernan said they use Aconcagua [1], another from Squeak implying that ScaledDecimal is broken [2]. A third seemed to say that FixedDecimal would be better [3], which I hadn't heard in the handful of times money has been discussed on list (usually ScaledDecimal comes up). For a simple case where someone wanted to write a small personal accounting app, which tool and which type would be the best place to start? Thanks!

Re: [Pharo-users] Ephemeric Cloud - new platform to publish Pharo web applications

Mike wrote <<< Thanks for pointing this out! When websocket support is ready on the ephemeric gate I'll add a ping to API server so application will work continuously without any effort. I think conceptually it should "just work". Also I plan to have a "sticky-run" option so you can mark some of ephemerics not to go to sleep mode. What do you think? >>> That sounds like a good approach. Just to dig into this a bit more, here is our first use case. We have an iPhone/web app which is a multiuser countdown timer. The data are hosted on Firebase. The iPhone app can set the time, and control start/pause. The web apps count down by themselves, but the start/stop/reset signalling is done in real time by the Firebase server. So, if you imagine a timer that is set to run for 45 minutes, we would need to signal start to the image. That would be reflected to all connected clients via wss, and then, for example, stopped with 5 minutes to go. We would need the app to remain live whilst a timer was running. However, we don't use the timers all the time, so keeping the whole app live might burn up more of the server's resources than necessary. Cheers Andy

Mike, that sounds really interesting. Will the instances support websocket connections, and if so, will that stop them from sleeping, i.e. if I had an app that sent out news updates via wss every 15 minutes to any listening clients, could it just continue to run, or does it have to receive a get/post request every 30 mins? Cheers Andy

where to report Telescope bugs?
by Peter UhnÃ¡k July 20, 2015

July 20, 2015

Hi, where do I report Telescope bugs? I downloaded latest TL via Pharo Launcher (build #192), but any opening/closing interaction doesn't work. 1. run TLDemos>>exampleCompositeExploringHierarchy 2. click on "+" 3. error MNU SubscriptionRegistry>>subscriptionsDo: Also does this "Work in progress" http://rmod.inria.fr/web/software/telescope/tutorial-visualization-developer mean that someone is actually working on it, or that it is planned someday = I just use the source code for the foreseeable future (or maybe if you have some internal docs available)? Thanks, Peter

Multiple sockets listening on same port
by Attila Magyar July 20, 2015

July 20, 2015

Hi, A number of times I ran into the situation where I started a http server but forgot that an other one was already running. This resulted strange behavior and led to confusion. The Socket class doesn't detect that the given port is already bound to an other socket. socket1 := Socket newTCP. socket1 listenOn: 9999. socket2 := Socket newTCP. socket2 listenOn: 9999. "I expected this to fail" Both sockets are in WaitinForConnection status and isValid returns true. Is this normal? Is there a way to detect this anyway? -- View this message in context: http://forum.world.st/Multiple-sockets-listening-on-same-port-tp4838417.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Overriding method - ExampleBuilderMorph>>#openModal:
by Jigyasa Grover July 20, 2015

July 20, 2015

Hi I have been using ExampleBuilderMorph and ExpanderMorph to build a accordion widget to display the search results of my application *searchQuick* which returns the list of file titles from the pre-loaded text files present in the resource folder when a string is searched for. You all are welcome to fork the code (https://github.com/jig08/sQuick_new) , try the infancy application and send in suggestions. As I have been using the ExampleBuilderMorph>>#openModal: to view the expanders, [ https://github.com/jig08/sQuick_new/blob/master/sQuick_new.package/PopUp.cl… LINE 33 ] I would like override this method to change the position and extent of the window which opens up because of #openModal: method. Help appreciated. Thanks Jigyasa
