Multiple sockets listening on same port

by Attila Magyar

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.

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

by Andy Burnett

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

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)?

[OT] Bill Gross: The single biggest reason why startups succeed

by Martin BÃ¤hr

Excerpts from S Krish's message of 2015-07-20 17:47:50 +0200: > Check out this amazing TEDTalk: > Bill Gross: The single biggest reason why startups succeed > http://on.ted.com/h15YB meh. read the transcript if you want to save the time, but to save even more time, here is the summary: "The number one thing was timing. Timing accounted for 42 percent of the difference between success and failure. Team and execution came in second, and the idea, the differentiability of the idea, the uniqueness of the idea, that actually came in third. ... The last two, business model and funding" he talks about the need to assess timing, but unfortunately doesn't tell much about how to do it, which is really the crux of the matter. in hindsight it is of course easy to see how the timing factor applies. but before, it's like trying to predict the future. and then, how does that relate to pharo or smalltalk in general? how can we assess the timing for pharo's success? did smalltalk miss its chance, so we should give up? or is it still coming? glass bowl anyone? there is no actionable advice in there. what shall we do? wait, and we'll know the timing is right when we see it? the only advice i can extract is that, because we can't predict the timing, don't put all eggs in the same basket, and while pushing pharo, don't push so hard that the future depends on the push to succeed. instead make sure that the project can continue even if the time is not right, so that it is still alive when the time is finally right. to actually make an attempt at prediction we'd have to look at developer needs. what are developers needs now, and does pharo deliver to fill those needs? (i believe it is pretty clear that pharo is still missing a few things, mostly on the integration side with other systems) can we predict what developers will need and expect in 5 years, and can pharo develop to match those needs? these questions are dear to my heart because i am asking them myself for my own project. i believe, i have a solution that many developers need, but as far as i can tell most developers are not aware of the problem yet. i hope that in time they will become aware, and that by then my project will be ready and thrive. we'll see. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/

It is a very interesting approach. Thank you for doing it. Can you share what cloud service do you use to run PharoCloud? (AWS, Google AppEngine, DigitalOcean, etc.) Regards! Esteban A.
