Terry 8-Jan-2010 [7340x2] | works fine here. |
can you get this? http://upload.wikimedia.org/wikipedia/commons/3/39/Brummdose.ogg | |
amacleod 8-Jan-2010 [7342] | yes |
Terry 8-Jan-2010 [7343] | Did you click the button? |
amacleod 8-Jan-2010 [7344] | yes |
Terry 8-Jan-2010 [7345x2] | there ya go |
i can hear it :) | |
amacleod 8-Jan-2010 [7347] | Still no sound...even when clicking the button |
Terry 8-Jan-2010 [7348x2] | it's playing here when you click it |
volume up.. all that stuff? | |
amacleod 8-Jan-2010 [7350x2] | thats weird |
yes | |
Terry 8-Jan-2010 [7352] | I guess you can check out the 'console' after hitting CTRL - SHIFT - i .. check for errors |
Janko 8-Jan-2010 [7353x2] | I just found out about a bug I was making and could only be discovered when cheyenne was first started, because some word was undefined then so it triggered an error, if I did some other things I couldn't see it but it would return wrong information in reality .. 1. is there any way maybe that would make cheyenne "reset" each request (for debugging & testing purposes, not production) .. the -w option seems not to do this. this could probebly be solved by wrapping also those parts in functions ... another question.. 2. Is there any way I could see all globals I created so I could find wtich ones I "leaked" unintentionally .. it would be very helpfull if rebol could let you define functs that would warn you if you used or defined any global words |
one solution is also that I define all words local to pageload in some object that is cleared on each pageload probably | |
Dockimbel 8-Jan-2010 [7355x2] | 1) I use -w 0 daily, works ok here. 2) see the solution in Core group. |
Btw, since 0.9.19, the RSP engine tries to catch all words defined in RSP scripts but outside of a local context in a hidden webapp context (one per worker process). | |
Janko 8-Jan-2010 [7357] | 1) I tried -w before (I remembered you hinted me the last time to use it to always reload) but it didn't make the difference in this case (as far as I can tell).. does -w only work with source discributtions? |
Dockimbel 8-Jan-2010 [7358] | It's : - w 0, -w only won't work, it expects the number of worker processes as argument. It should work ok with both source and binary version. I'll make a test right know with 0.9.19 binary... |
Janko 8-Jan-2010 [7359x2] | I tried cheyenne -vv -w 0 ; and now cheyenne - w 0 .. with same result |
maybe I should better explain what I am doing so I won't steal your time here (and it's no problem basically as I will turn all global words that are only locally needed to something else) .. it's bad coding practica anyway | |
Dockimbel 8-Jan-2010 [7361x3] | 0.9.19 binary works ok here in -w 0 debug mode. |
Try testing with this script : <% either value? 'azerty [ print "debug mode not working" ][ print "debug mode is working ok" set 'azerty 1 ] %> | |
Hit F5 several times, it should always answer ok if Cheyenne is running with -w 0. | |
Terry 8-Jan-2010 [7364x2] | Doc, Im going to develop some rebol and flash apps that connect to Cheyenne via the websocket. What is the procedure for the handshaking? |
I haven't heard a single sheep all day? No one is trying the demo :) | |
Dockimbel 8-Jan-2010 [7366] | Web socket protocol is fully described here : http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol Quick protocol overview : http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol-68#section-1.2 |
Terry 8-Jan-2010 [7367x3] | Will try some experiments using Canvas and websockets.. here's some great examples http://www.chromeexperiments.com/ |
Yeah, Doc.. was hoping for a condensed version seeing as you've done the whole learning curve. | |
This one is nice http://www.chromeexperiments.com/detail/depth-of-field/ | |
Gregg 8-Jan-2010 [7370] | Isn't that Doc's old v-balls demo? ;-) |
Kaj 8-Jan-2010 [7371] | Thanks for the links, Terry. Busy bookmarking here |
Terry 8-Jan-2010 [7372] | Another.. try shaking the browser http://mrdoob.com/projects/chromeexperiments/ball_pool/ |
Gregg 8-Jan-2010 [7373] | Indeed. Thanks here too. |
Terry 8-Jan-2010 [7374] | Now THIS is very cool use of CANVAS http://www.universaloscillation.com/chrome/popups/ |
Kaj 8-Jan-2010 [7375] | Hm, those last two work fairly well on my ancient Firefox 1.5 |
Terry 8-Jan-2010 [7376] | Try it on Chrome.. much faster. |
Terry 9-Jan-2010 [7377x5] | WS to AtomDB demo http://shinyrockets.com/atom.html |
Demo includes; - websocket roundtrip timer - ATOMDB query timer - Example of changing a graphic when socket is closed. - Font-face demo (another HTML 5 feature that allows ANY font in a webpage .. see the <style> on the page | |
Font used is DroidSans.. can download for free from -> http://www.fontsquirrel.com/fonts/Droid-Sans | |
Funny thing is, if your "ATOMDB Query time:" changes randomly? That means someone else is running the test, and their results are being broadcast to your browser. HOW COOL IS THAT! | |
A couple lines of code and you could create a live chart displaying the various times folks are getting, including geo location etc | |
Janko 9-Jan-2010 [7382x2] | What woudl be the best way to do some casual source code protection of cheyenne webapp if you want to distributte it as a "download and install" option. I guess I could make some sort of code obfuscator that would change the names to something without meaning, is there anything better one could do? |
I am usually for not complicating with this but this webapp is of classical competetive scene as will also still run as online service so I want to prevent that competitors could too easily study it , find any possible weaknessess etc... | |
Dockimbel 9-Jan-2010 [7384x2] | Janko: I have in my todo list a full virtual system to add to Cheyenne allowing embedding webapps in a encapped Cheyenne. It can be done by replacing every filesystem accessing functions (DO, LOAD, READ, WRITE,...) by custom ones getting files from memory. The hard part is to integrate such approach within Cheyenne preserving perfomances for normal filesystem accesses while avoiding redundant code, this needs time for designing and prototyping. I can't see an easy way to protect you webapps right now, but maybe other might have found a way to do that? |
Terry: interesting links, so we might get rid of flash soon, no? | |
Kaj 9-Jan-2010 [7386] | Unless we need Flash to get at web sockets from older browsers |
Dockimbel 9-Jan-2010 [7387] | Can't older browsers use some JS layer simulating web sockets like js.io library? |
Kaj 9-Jan-2010 [7388x2] | I hoped so at first, but it seems to be a different system |
The only way I've heard of to do WebSocket in older browsers (almost all of them right now) is the Flash implementation | |
