Re: [OT] A couple of links about Gnome and usability
Another thing you might like to think about is running a Linux distro on a second hard-disk or partition in a PC running Windows. If at all possible go for the second hard drive option; I have managed to muck a lot of things up trying to go the second partition route. Some Linux distros are very fiddly indeed to install, but Mint Linux and Ubuntu are as easy, if not easier, to install as Windows and Mac. Download an install disk: http://www.ubuntu.com/download/ubuntu/download http://www.linuxmint.com/download.php burn your ISO image to CD/DVD (that depends on its size) and reboot your machine from that disk, and follow the instructions: http://www.linuxquestions.org/questions/linux-newbie-8/how-do-i-install-linux-on-a-second-hard-drive-221331/ http://danleff.net/myarticles/fedorainstall/linuxinstallharddrives4.html - Another option, which is probably the safest bet of all, is to buy a second hand PC (any Pentium 4 will do, with a min. of 512 MB RAM) and install Linux on that. Certainly, in my part of the world HP compaq Pentium 4's with 1-2 GB RAM are as cheap as chips [40 Euros]. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: Specify file download path with irev/revignitor
Stephen, (and Jacque), Thanks again for your reply -- got it about the browser controlling downloads for security reasons. Also, some very good information here. I hadn't known about StackRunner and your idea of a thin client is great -- I can probably pre-install it on the MP3 players before we send them out. Simply have folk plug the players into the USB port, and when it shows up on the desktop, launch the client to make sure they have this month's content. (Rather than music, we're doing lectures and seminars, etc. Savvy users are already handling their own downloads and ipods. This project is an attempt to wean our non-techie customers off mailed out CDs... gotta be something grandpa and grandma could handle.) Also great link to the LiveCode Server docs -- I did not know about those! I got the freebie version of RunRev when I signed up for hosting at on-rev and have been working with that and it's user manual... Appreciate the help. Tim Selander Tokyo, Japan On 3/25/12 11:13 AM, stephen barncard wrote: Ah - well that's the thing - the security features of web browsers strictly don't allow control of the user's machine from the server side - that's what those warnings for the user for plug-ins like flash and the livecode plug-in are about. Changing stuff on a remote machine by a server is forbidden for users' protection - otherwise the web would be unworkable thanks to the criminal element. Those same protections are built-in by design for Javascript on the browser side for the same reason. Hence the invention of the Livecode plug-in. That's why I thought you had a 'thin' client on the user's side that could do what you want; your mentioning of sending out players. You could do this with a Livecode plugin, but that would require users to install something on their machines anyway, and the future of this plugin has not been defined lately, hence the recent discussions online. I feel a thin client can give a better UI experience anyway and a lot easier to maintain and support. Your comment about the online documentation of Livecode server is correct - a lot of new info is available with the version notes of the latest version (5.0.2), but I get those through my involvement as a purchaser of the server product to run on my own web host. I assume you've seen what the Runrev site offers: http://www.runrev.com/developers/documentation/server/ These limitations that web browsers have do not diminish the coolness of Livecode server; it just requires being open to do it another more secure way. You never want to do stuff without the permission of your users, that would definitely creep them out. Depending on the scope of your project, number of users, etc, is it possible you could do this entirely 'in the cloud'? That way you could control the addition and deletion of files, giving each user their own space for files, and provide the player in a browser. Otherwise I'd suggest you build a thin user client for her to download and live on her machine. Or possibly use a 'splash screen' approach where a small compiled application would hold the basic livecode 'stuff', and a script could do a go URL http://musicsource/playerstack.lc; on startup thereby loading your latest stack version of your player that could be 'updated in the store' anytime you wish, as that stack would live on your server. Yet this client could have access to any folder your user has access to on her machine. This thin client can then easily manage the audio files in the user-selected (or default) folder. I've done this myself as a convenience to run many utility stacks that I store on my server, and run on one of my several machines, a kind of network based Livecode stack player. Mine is a network variation of Ken Ray's Stackrunner.http://www.sonsothunder.com/devres/livecode/downloads/StackRunner.htm It sounds like a cool project - being open and controlling expectation of what can be and can't be done is the key, work around those limitations (that everyone else has to deal with), and move forward. Livecode gives us many ways to create the solution to our problems. hope this helps. On 24 March 2012 17:00, Tim Selanderselan...@tkf.att.ne.jp wrote: Thanks for your reply, Stephen.

Re: Collisions
Richard, Collision detection is the easier part. Just calculate the distance between centers and, if it is greater than the sum of the radii (assuming they are circular) you have a collision. The more difficult part is the physics, what happens after the collission. Are they of equal mass and size? You need to conserve momentum and energy. To get started you may look at a pool game.

Re: Collisions
P.S. In the simplest case, equal masses, just interchange the velocities of the two balls after the collision. Proof: If one assumes that the solution is unique, and since interchanging the velocities conserves momentum and energy (for balls of equal mass), this solution is THE solution.

Re: Collisions
This works only if the balls hit head-on. Otherwise you need to do the trig. As a simple example, say there are two balls headed toward each other. Each has a radius of 2^.5. Ball A is moving at -2 units per second on the x axis, i.e. to the left, and its center has a Y coordinate of 2. Ball B is moving at 2 units per second on the x axis, i.e. to the right, and its center has a Y coordinate of 0. When the balls collide, they will be 2 units apart both horizontally and vertically, hence they collide at a 45 degree angle. Let's say that they're at 0,0 and 2,2 at the time of the collision. They won't simply exchange velocities. Their original motion on the x axis is translated entirely into motion along the y axis. After the collision, ball A will have an X coordinate of 2, and be moving at 2 units per second on the Y axis, i.e. up. ball B will have an X coordinate of 0, and be moving at -2 units per second on the Y axis, i.e. down. You need to calculate the angle between the balls at the moment of collision, and use the sine and cosine to figure out what happens from there. All of the above is from my head so feel free to check me. On Sun, Mar 25, 2012 at 8:56 AM, Jim Hurley jhurley0...@sbcglobal.netwrote: P.S.

For example from Nine ball... function resetVel xx,yy,xx',yy',vxx,vyy,vxx',vyy' put xx,yy into pme put xx',yy' into pOther put theLineAngle(pme,pOther) into tCentersAngle put tCentersAngle into tCa put xx,yy,xx+vxx,yy+vyy into tVelVector put theLineAngle(tVelVector) into tVa put sqrt(vxx'*vxx'+vyy'*vyy') into v' put sqrt(vxx*vxx+vyy*vyy) into v put xx',yy',xx'+vxx',yy'+vyy' into tVelVector' put theLineAngle(tVelVector') into tVa' --Angle of the vVector relative to the line joining centers put tVa - tCa into tVrA put tVa'- tCa into tVrA' put v*cos(tVrA) into vR' put v*sin(tVrA) into vT put v'*cos(tVrA') into vR put v'*sin(tVrA') into vT' put vR*cos(tCa) - vT*sin(tCa) into vxx put vR*sin(tCa) + vT*cos(tCa) into vyy put vR'*cos(tCa) - vT'*sin(tCa) into vxx' put vR'*sin(tCa) + vT'*cos(tCa) into vyy' return vxx,vyy,vxx',vyy' end resetVel Jim Hurley Geoff Canyon wrote: This works only if the balls hit head-on. Otherwise you need to do the trig. As a simple example, say there are two balls headed toward each other. Each has a radius of 2^.5. Ball A is moving at -2 units per second on the x axis, i.e. to the left, and its center has a Y coordinate of 2. Ball B is moving at 2 units per second on the x axis, i.e. to the right, and its center has a Y coordinate of 0. When the balls collide, they will be 2 units apart both horizontally and vertically, hence they collide at a 45 degree angle. Let's say that they're at 0,0 and 2,2 at the time of the collision. They won't simply exchange velocities. Their original motion on the x axis is translated entirely into motion along the y axis. After the collision, ball A will have an X coordinate of 2, and be moving at 2 units per second on the Y axis, i.e. up. ball B will have an X coordinate of 0, and be moving at -2 units per second on the Y axis, i.e. down. You need to calculate the angle between the balls at the moment of collision, and use the sine and cosine to figure out what happens from there. All of the above is from my head so feel free to check me.

Re: [OT] A couple of links about Gnome and usability
As a Mac-o-philiac I have spent some time playing around with PearOS, and can honestly say it sucks; it being neither one thing nor the other. Also, for Mac types; the initial set up does NOT have desktop icons, and it is a right cough-cough-cough finding one's Home folder and so on. The eye-candy is Mac-like; the functionality is not. And by fudging around with GNOME 3 to produce a supposedly Mac-like interface they have just obscured some of the useful features of GNOME 3. This reminds me of attempts in the past to build Linux distros with interfaces that are clones of Windows XP; similarly silly. When one moves to another operating system there is a learning curve involved, and it is disingenuous to pretend there is not.

side-by-side iOS external SDK
I currently use XCode 3.2.6 on OS 10.6.8 with IOS external SDK R7 applied to it to build iOS externals for iOS 4.3. (I build iOS standalones for iOS 4.3 using LiveCode 4.6.4--sometimes with such externals--using XCode 3.2.6.) I would like to also build externals and apps for iOS 5. I think then I'd like to set up this side-by-side with the above configuration: XCode 4.2 for Snow Leopard LiveCode 5.0.2 iOS Externals SDK R10 (I think I got the compatibilities straight on that, but, if not, I welcome feedback.) It is my understanding (or misunderstanding, perhaps) that the latter configuration will build apps and externals for 5 only, not 4.3, so I need both. If possible, I'd like to do the side-by-side setup with the same user and on the same boot. Is this even possible? Or do I need to install these on different boot drives? (I also want to keep XCode 3.2.5 for PowerPC externals.)

Mint is wonderful and XFCE is a very straightforward and traditional DE. Both are fine recommendations, although I am leery of Mint rolling Debian which is the only official XFCE version I could find on the Mint download page. Is it perhaps an alternative install within the Gnome DVD? One thing that maybe could be said that for someone who wants mainly to have a Linux install available to test Livecode apps and perhaps run Livecode to tidy up applications being built for Linux, it may not matter at all which distro or DE you run, the only caveat to that being that you're better off installing a 32-bit version saving you the step of installing 32-bit compatibility libs. So long as you can get easy access to your stacks and apps from your Mac, and create an easy access to Livecode on your your Linux install, you might not find any reason to prefer one distro or DE over any other. That said, I think, Richmond, while it absolutely true that each OS requires adjustment and learning, this is a much more involved topic in approaching Linux due to the extreme variety of choice regarding distro and DE. People seek a certain comfort level and familiarity can be a major factor. The disruption of familiarity is one of the roots of the current DE rumblings. I don't see anything wrong at all with customizing the DE experience to mimic either OS X or Windows, if that makes the user happy. The comment about water wings and training wheels is silly on two levels. It ignores the real value of them - enabling the inexperienced to participate in and enjoy an activity in comfort and safety as they gain familiarity and confidence - and overstates the danger. It's ludicrous to say that anyone who rides a bike with training wheels will never ride without them, or who floats with water wings will never learn swim. Surely you don't believe that! As an extension of that argument, why not promote Gentoo, Arch, and Slackware? Higher learning curve = more genuine experience?! I suspect you don't actually believe that, at least not when put so directly. It is an old attitude in the Linux community that is thankfully becoming less prominent. Please be cautious not to promote it!!! I have never used any version of Pear OS and only presented it as an available alternative with a rationale for why Pete may find it attractive. Have you tried the most recent version? Some people seem to like it, http://sourceforge.net/projects/pearoslinux/reviews/ . Here's a review of a pre-release version which may be interesting: http://www.linuxbsdos.com/2012/02/15/pear-linux-comice-os-4-beta-1-review/ . Just for fun, I'm about to install it in a VM to have a look. (slow download) My DE is KDE 4.8 and I like it very much. I don't use all its features but it does some things that a really love. It works for me and makes me happy. While it's very popular (despite Richmond's feelings about it), it doesn't suit everyone (see Richmond's feelings about it - feelings he's perfectly entitled to, of course). I feel comfortable recommending it as a good option. Kubuntu has a very poor reputation among KDE users, but it sounds like Mint is improving its KDE version. http://youtu.be/ou9HIdlSQq0 http://youtu.be/Em3KOFvQSTY I do agree with Richmond that Mint or Ubuntu may be the most foolproof way to approach Linux.
