I don't think "access the media" means that you should claim that you can open the file. When you list a MIME type, you're claiming something more than just an ability to open the file. You're claiming appropriateness as a default handler. I expect that you can open an image without claiming that Etoys is suitable for opening images. If not, then please file a bug for the datastore. Only the application/x-squeak-* things are appropriate.

The media type for Speex in Ogg (common .spx files) is audio/ogg. audio/x-speex or audio/speex as it's in the process of being registered is only used for RTP. audio/x-speex+ogg would be another of those crazily made-up media types with no purpose. I'm a bit bothered with all problems Sugar suffers from media types. I can't still find the cause why Speex does not work in the applications where it should, even though everyone suspects it's a media type problem. I for one can't find it. I have tried several "combinations" in case gstreamer expected any of them, and it led to nothing. On the other hand, correcting the media types for Ogg video (video/ogg as opposed to three crazy x-something experiments) makes Theora video stop working. I can't understand anymore who's to blame, if either the applications like gstreamer and etoys which are going for non-standard media types or Sugar, which relies too much on them. -Ivo ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

As an outsider / random developer, I understand why Etoys should declare it can handle, say, text/html, but I don't understand why Etoys should be the default handler for text/html. Etoys isn't the default handler for clipboard / journal text/html mime-types, is it?

It's like some kind of land grab. Well, Etoys is a multimedia environment and should handle most media types. For authoring active essays where you combine simulation, text, pictures etc you must be able to access the media. Here is the list of MIME types Etoys claim: application/x-squeak-project; application/x-squeak-image; application/x-squeak-object; application/x-squeak-source; application/x-squeak-archive; text/html; text/rtf; text/plain; image/bmp; image/gif; image/jpeg; image/png; image/pnm; image/x-xbitmap; image/x-portable-anymap; image/x-portable-bitmap; image/x-portable-graymap; image/x-portable-pixmap; image/pcx; audio/midi; audio/basic; audio/aiff; audio/wav; audio/x-speex+ogg; audio/x-speex; application/zip; application/x-shockwave-flash; application/x-truetypefont; application/ogg Shockwave implementation is quite dated, around flash version 3. Zip works great on other platforms, but with Journal and the ZIP UI using a tiny font is is quite useless. Html rendering is not great, but works for basic simple html.

Re: How to create a new MIME type for a Sugar activity?
Albert, I have decided against creating a new MIME type for my application. It turns out that the problems I was experiencing were caused by issues with the Journal. In the latest release the Journal has problems dealing with larger files (30 meg or so). When you try to use one of those files in an application the app acts as if no file was specified at all. I got a developer key and updated the OS and now my app works just fine. It isn't that big a problem to avoid opening the file with EToys. My real issue was opening the file with my own app and having it not working. I thought having my own MIME type would solve the problem, but that was only because I didn't understand what the real problem was. James Simmons Albert Cahalan wrote: The faster sugar can phase out MIME the better. The MIME type of application/zip works, but Etoys is using that one too. Whatever you invent, Etoys will claim it in the next release. It does not matter if Etoys has any ability to handle the data.

I would like to add some general remarks: - Radio off is already there. So, the user can turn it off and save power. - Mesh off is due to a future release. It's just not been a priority on the wireless front recently (and it shouldn't be, right?). - Infrastructure is not always present. The default is not present. That's exactly when the mesh is important. I believe it would be useful to set up a goal in terms of battery autonomy and then see how to achieve this prioritizing the cost/ benefits involved in cutting/compromising this or that. -- Carrano ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: mouse unstable on rc2
I don't know if this is related, but if I leave mine booted up for long enough, the mouse jumps to the lower right corner every second mousepad touch or so, making it impossible to operate the box (even in the terminal, because jumping to the lower right corner causes the black border with activities to appear).

mouse unstable on rc2
I upgraded the machine that I've been useing daily for the last month, and I'm noticing that the trackpad is acting very skittish at times. a reset will clear it up for a while, but it comes back. I have not had this problem on this hardware with prior builds. I have also seen this on my second box, but I haven't been useing it as extensivly so I can't promise that it never had a problem before (it was still on build 650 prior to this weekend, with no noticed problems.

I'm familiar with two-way transmitter power requirements as I am a Ham and also do a fair amount of emergancy services communication work. in my experiance there, the transmitter can take so much more power then the receiver that even a small amount of transmitting can match the power needed to run the receiver for a significant amount of time (I'll point out that those radios did transmit _far_ more powerful signals than the WLAN does, so the balance may be different) > So if you are using transmit power you are probably doing useful work. > (That's assuming that you call maintaining the mesh topology useful and > things like that.) almost, what I am thinking is that there may be value in listening to the mesh without transmitting to gather the state of the mesh and decide if you need to participate and transmit. if the mesh is extremely chatty (which I am gathering from other posts) there may be noticable savings in just listening, but not participating in maintaining the mesh, unless there aren't enough other machines doing so.

To first order, the transmitter doesn't take any power unless it's actually transmitting something. After that, it's linear with how much you transmit. There may be significant overhead on each packet. So if you are using transmit power you are probably doing useful work. (That's assuming that you call maintaining the mesh topology useful and things like that.) -- These are my opinions, not necessarily my employer's.

It's supposed to break out of suspend when the next packet arrives. Oh! Because the activity sharing/association stuff uses multicast packets, and there's bug http://dev.laptop.org/ticket/4616, "Mesh doesn't resume from suspend on reciept of multicast packets". If you create some file somewhere, then Ohm won't suspend. (Chris, how about adding a real control for this into the olpc-control-panel?) You could do the research to find that file, then create it, then see how Distance works. I can see that you'd have problems sharing the two instances, due to the bug, but then once they are paired, they ought to be using unicast packets (via TCP), right? Sending a unicast packet would wake the laptop on the other end out of suspend (this is supposed to be working -- but takes a full second or so). So is there another bug, either in Distance, in the infrastructure between shared activities, or in suspending, that is causing Distance to fail once fully shared? Unfortunately, fixing that multicast bug may be hard. It took months to convince OLPC that it ought to get fixed, despite the fact that it breaks every incoming IPv6 connection. The WiFi firmware supposedly already supports resuming on reciept of interesting multicast packets; we just aren't asking to be awakened for them. The problem is that the laptop's presence software is listening to (and transmitting) way too many multicast packets all the time -- so it would pop out of suspend all the time. Once the presence service gets the network traffic down to a dull roar, and the suspend/resume time gets shorter, it'll be easier to fix.
