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 | |
Janko 9-Jan-2010 [7390] | I think not, older brosers only have xmlhttp (ajax) option, iframes and other comet like tricks but they can't do a socket .. I haven't seen what js.io does.. if you wanted to make a "pure" html chat without comet or polling you made JS that talked to invisible 1px flash and flash has XMLSocket or something like that. But I heard recently that it can be used for other things than xml .. |
Terry 9-Jan-2010 [7391x3] | Flash would be the best way to interface with older browsers via sockets. JQuery <=> Flash <=> Cheyenne Although it's not necessary, I only push Javascript back to the DOM manipulation. (Hence the need for a JS dialect.. specifically JQuery) |
Doc, Flash's core strength (animation) is quickly evaporating. | |
Hmm, the last person to run the atom demo had a 6971.28.. second 'round trip' .. wonder what happened there? | |
Terry 10-Jan-2010 [7394] | I think it's official.. Flash is dead. I was modifying some flash xmlsocket based apps to work with Cheyenne websockets, and then realized, why bother? I can do it all with HTML 5 HTML 5 has.. CANVAS AND VIDEO http://www.youtube.com/watch?v=Kdf0x8am1cg&feature=player_embedded# chroma key effect. http://www.youtube.com/watch?v=ZN_r9jxL0-A&feature=player_embedded LOCAL STORAGE Chrome has SQLite built in, accessible via JS |
Pekr 10-Jan-2010 [7395] | Flash might move to RIA (but who's interested to do real apps in Flash?) or - many mp3 etc vendors are doing their UI using flash. As for html 5, we are still talking vapor, unless it is supported by most browsers, which are used by most ppl IE still has 62% of share, and IIRC CSS3 and HTML5 are going to be supported in IE9. How long do you think will it take to replace those 60% of IEs out there by IE9? Well ... I know what you are trying to say ... it is inevitable ... but ... not yet, not yet :-) .... this probably belongs to advocacy though .... |
Dockimbel 10-Jan-2010 [7396x5] | Flash might move to RIA : it's already done, it's called "Flex". |
who's interested to do real apps in Flash? http://www.adobe.com/products/flex/buzz/customers/list.html | |
ActionScript, which is Flex's programming language is now in #19 in Tiobe's index. | |
Maybe Flash usage for sockets, animations, games and videos might start dropping soon, but as an application framework engine, its usage keeps raising. | |
rising | |
Terry 10-Jan-2010 [7401x2] | raisin |
I used flash as an application framework for an engineering co once.. one of the biggest mistakes of my career. | |
Dockimbel 10-Jan-2010 [7403x5] | SVN r59 : experimental mod-upload released. This new mod adds server-side API for querying realtime progress info on uploaded files. See the demo : http://localhost/upload.html(not commented yet). Current restrictions: - works only when posting one file at a time in a given <form>. - can't make it work for IE (IE seems to have an issue with setTimeout( ) method). |
Help would be appreciated to solve or workaround the setTimeout() issue with IE. | |
If you're testing the upload demo locally, be sure to pick a file big enough (at least 10 Mbps). Don't worry about uploaded files, the target script (show.rsp) doesn't save them, so the server's copy will be deleted as soon as the upload is finished. | |
This mod-upload version is unsuitable for production yet, the upload tokens on server are not garbage-collected. | |
10 Mbps => 10MB | |
Terry 10-Jan-2010 [7408x2] | After updating the SVN, I get a id: 'cannot-open arg1: "/c/websock2/Cheyenne/mods/mod-upload.r" and the file is not there. |
should have some default error trapping for socket-apps in the http.cfg file, no? One typo brings the whole server down. | |
Terry 11-Jan-2010 [7410x3] | Working on some websocket experiments.. http://shinyrockets.com/exper.html - simple canvas game... Losing the game publishes the fail , ip and port to everybody. |
I'm curious as to lag around the world (should add geocaching i suppose) | |
Doc, any thoughts on a standard protcol for sockets? xml? | |
Dockimbel 11-Jan-2010 [7413x7] | mod-upload: it was missing, it's in the repository now. |
standard protocol for sockets : JSON. | |
take the reb-services dialecting approach and format it in JSON ;-) | |
Typos errors in config file should be caught, what kind of typo was that? | |
Btw, keep in mind that defining a "standard" protocol above web sockets goes against its primary purpose : provide a general purpose packet-oriented communication channel. It would be like defining a "standard" protocol above TCP. For practical usage with JS clients, JSON data format is the way to go. Don't forget that the web socket implementation in Cheyenne is partial, only TEXT frames are supported currently. I could add the binary support also, but I don't have a need for that for now. If someone has a *real* need for that, let me know. | |
IE issue fixed with upload.html. It wasn't a settimeout( ) issue, it was a IE caching all the AJAX responses. | |
SVN r61 FEAT: added request/store function to help manage uploaded files (see %changelog.txt). FIX: IE issue with upload.html (cache issue). Works ok in IE now. DOC: upload API documented in %www/upload.html. | |
Terry 11-Jan-2010 [7420x2] | JSON was my first thought.. but I think I'll build a custom "data format" using triples to keep inline with the back end.. still thinking about it. |
I guess the binary support would go hand in hand with your new upload script? | |
