Comments on: Sneak Peak: Cambio

Cambio is a program concept, from PalmSource, designed to facilitate exchanging and sharing programs on your handheld. It takes advantage of both Bluetooth and IR to transfer rated lists of apps in a pseudo, P2P file sharring like manner. PIC correspondent Davy Fields caught a demonstration by PalmSource and brings us this sneak peak.

Kazaa will be released for PalmOS 5 in the late 4th Quarter 2002.

Lol, Kazaa for the palm. I don't know about the security of this. If you could connect and then take files from a person that you have been in contact with before just by being 30 ft away from then. It gets king of scary thinking of how this can be missused. I understand right now the program has been crippled so that no files that might contain personal information can be sent, but that is not acceptlable because there are other files that might not have important or personal information that need to be sent.

I saw this running the other night. You can't connect unless the other person accepts the connection, and you only 'see' ratings for programs the other person wants you to see, and only get programs that they have rated. So there is no way you can get things from someone else without their knowledge.

The person giving the demo also said that Cambio is designed to help beginners (NOT the folks on this forum :-)) who don't know about beaming. I think the idea is to provide another way for people to try out new software.

How is pulling down the menu and press "beam" any more complicated than this !? ... it would be nice if you could explain how complcated the Beam function is ...

It is only easy if you

a. know that your device CAN beam programs
b. know where the command is that lets you do it.

Once you know - you are correct: piece of cake.

Makes me think that PalmSource has something else up their sleave for this app...

well...the article mentions Bluetooth - the best reason for this software.

Will Cambio need to be running on the "program giving" palm, or just the receiving palm?

I expect it would run equivalently to a hack - running in the background - but you bring up a good point...

if someone connects to me and starts grabbing files, it'll slow down my handhelds data transfer speeds...

still, I expect you could continue to do other things, if you made the 'server' piece run in the way that a hack does - but maybe not, when you IR beam it doesn't let you do other things. Definately want to make it easy to disable :)

This would be excellent for commercial stuff too I think.

Imagine having an IR/Bluetooth booth selling apps/E-books or distributing tour or event information!
That would be very cool as handhleds become more common. I am still looking for that e-book booth to show up in an airport!

Why, even some poor slob with a White Elephant Zire could get in on the fun!
Okay, that was a shot, but it is true. If it works over IR, your're in!

This is one of the great feature I've been looking for. It really make me think back before purchasing PPC to replace my very old PalmV.
However, the Bluetooth features might be make using our Palm is prohibited on air plane. :(

I dunno....

sub_tex @ 9/28/2002 2:58:12 PM #
I think when i ask a friend for a new app he has, he tells me which is great and then beams it to me.

It's never me going through the apps on his pda and then deciding which i want based on his ratings. The "ratings" is a lot faster if he just tells me which.

For the time it takes me to stand in place with our pdas lined up for IR and go through his apps, he could have just sent the ones i was interested in already.

The one cool thing i DO like about this app, though, is the ability to cue up mutliple items at once.

I'm sorry - but this is one of the dumbest programs I've ever seen. It overcomplicates simple software sharing. Now we know what the geniuses at PalmSource have been up to. What are these guys thinking? Sheesh...

RE: Dumb
I.M. Anonymous @ 9/28/2002 4:19:37 PM #
Totally agreed. If that is where development hours are spend, PalmSource seems doomed to me.


RE: I dunno....
I.M. Anonymous @ 9/28/2002 5:48:44 PM #
I agree, the scope for this app seems limited.

I wonder if it can be used to beam multiple apps simultaneously from a laptop to Palm (ie, without having to accept each one and start the process again)?

I agree that there's a lot better things the folks at Palm Source should be working on. Still, I doubt this program took much effort to write, and it's a good Bluetooth demo.
Way to go PalmSource!

Not... What a dumb program. Why complicate something as simple as sharing a file with a rating system?
Think Bluetooth
I.M. Anonymous @ 9/28/2002 8:39:34 PM #
At PalmSource in February someone mentioned that the final version would use IR or Bluetooth, and was meant for beginners who wouldn't know about beaming or IR or even that the device has a menu.
RE: Way to go PalmSource!
I.M. Anonymous @ 9/28/2002 8:55:31 PM #
Well, maybe dumb for you, but for many new Palm users, finding the Beam menu item or even knowing that it exists (or that you can 'beam' something) makes sharing programs a non-starter.

I like the idea, but I'd like to get a copy and have a chance to play with it before I could really say.

RE: Way to go PalmSource!
I.M. Anonymous @ 9/28/2002 9:07:49 PM #
I think that if new users are that inept that they can't find/operate the built-in beam function, they won't know how to load/run or care to use this program. Thank you.

> Now we know what the geniuses at PalmSource have been up to. <

A typical PIC troll comment. At PalmSource in February, the guy in the keynote address said that Astraware had built this for them (those guys write some pretty cool stuff).

If the writer has such low regard for PalmSource, it kinda makes you wonder why he/she spends any time on this website... :-)

Why not use BeamPRO!??!?!?!??
Transfer applications that way!?

"Now thats just PRIME!"
RE: Way to go PalmSource!
bcombee @ 9/29/2002 5:17:12 AM #
The key thing this does is let the user who is going to receive the applications make the choice about what to beam (or send, when using Bluetooth). You can beam your app list over to someone, then later after they've made choices, they can grab all the apps they want from your device. They can also beam back the catalogs of other people, so you can find out about programs you might have missed.

It's a nice tool for people that tend to evangelize Palm OS, but its probably not something you'd use everyday.

It's a nice way to spread trojan horse and virus too. And since when this sort of rating has any meaning over time?
RE: I dunno....
I.M. Anonymous @ 9/29/2002 11:37:10 AM #
I think the real key to this app will be with BlueTooth and a device that is essentially always on (think treo/new i705 replacement). I can set a list of programs to share to anyone, and with little (hopefully no) effort by me, individuals can be downloading programs from me. It's PAN based Napster.
RE: I dunno....
bcombee @ 9/29/2002 12:17:12 PM #
Well, the current version does not live in the background -- you have to be in the Cambio application to support a transfer of applications. Someone could start a session to you while you were in another app, but the device would have to switch to Cambio to finish things.

Running on some sort of BT hub, maybe. But novices that would have trouble beaming are not going to be buying high-end BT devices. Even less likely they'll have even one friend that is BT-enabled.

1-3 stars? thats kind of dumb. Most things are rated with up to 5 stars.

At the demo someone said that they were considering more stars but wanted to keep things simple until more people saw and used it. I agree I'd like to see at least 4 stars or even 5 if there is room.

Kesh @ 9/28/2002 10:23:35 PM #
Not to mention that you can queue transfers, and take advantage of Bluetooth with this. Not such a bad little app.

Now, if Palm will just integrate Rendevous networking via Bluetooth into OS 5.x, I'll be happy. :)


I.M. Anonymous @ 9/29/2002 5:09:59 PM #
I am not going to spend the time rating all of the apps on my PDA and then let other people, even friends, browse a list of what's on my Palm. Might be a good app if you're in junior high and have a PDA and want to swap games with your buds.
Palm seems to be putting a lot of effort in the wrong direction.
RE: Pointless - totally
nrosser @ 9/29/2002 10:01:17 PM #
Could not agree more. This is mostly useless. Rate my apps? (why? - that's insane). and the auto-beam/Ir/BlueTooth? I mean - c'mon. Even other super Palm geeko's like me don't do a ton of app beaming.
Surely there's more here than meets the eye. Maybe.

This is Palm Source supprting the palm software developer community. This is Palms way of pushing one of its leads over MS.

Its the software!. I have found myself often beaming the same 4 or 5 programs to every newbie I meet in the hospital. This would just make it easier.

Anything Palm can do help spread 3rd party software should be hailed as great.

Campio also mean Exchange

I.M. Anonymous @ 9/29/2002 10:37:58 PM #
I think Exchange would be the appropriate term but it already taken by MS Exchange.

If you are traveling, I think you have seen this Campio in your Money Exchange kiosk.

RE: Campio also mean Exchange
I.M. Anonymous @ 9/30/2002 8:18:23 AM #
It's "CamBio" with a "B", not "CamPio" with a "P". I may be remembering wrong from when I took Spanish in school, but I thouth "Cambio" meant something more like "walk". Any Spanish speakers who can clarify this?
RE: Campio also mean Exchange
I.M. Anonymous @ 9/30/2002 11:39:50 PM #
Cambio means 'swap' or 'exchange' - the project name was assigned by a manager at PalmSource who was originally from Mexico.

Can Bluetooth be turned off to save battery life?

I.M. Anonymous @ 9/30/2002 12:42:50 PM #
I remember one of the first tips that I give out is to turn off beaming.

I hope that bluetooth is not constantly "On" and scanning the airwaves. I know that my wireless phone needs constant charging.

Even if that is very low power, having someone wake my device to broadcast will be a drain. This is more of a problem if anyone can wake the pda. For instance, someone sits at Starbucks and checks what everyone else likes.

That makes it feel like an unusual popularity contest for Palm software.

See? This is good development at work. I like it.

When will it be available?

Will this piece of software be available for download when the Tungsten T (which has built-in bluetooth) is released?
