Re: AFR: Sony's 2-screen Tablet P: a good idea gone wrong
Interestingly enough... e ink screens CAN fold. They are just too slow for general tablet use.

I excerpted freely below; see the link for the entire story. --gnu] http://www.afr.com/f/free/technology/digitallife/g_ZWzfPcJsePV9VdQfxY9w1H Sony's tablet a good idea gone wrong PUBLISHED: 30 Mar 2012 The best thing that can be said about Sony's new $729 Tablet P is that it means well. The central idea that must have led to the construction of the Tablet P -- that iPads are too large -- is pretty sound. iPads are too large, at least for a lot of users (the staff here at the Digital Life Labs included), and at least for a lot of applications. So, yes, Sony was trying to solve a genuine problem when it came up with the Tablet P, a tablet that folds in half so you can slip it into your pocket or purse, that's light enough to read e-books on for hours without your hand cramping, and small enough that you can use it as a camera without looking like a total tool. The trouble was, they couldn't make it happen, not with today's technology. To have a tablet fold in two, you either need one screen that folds in two, or you need two screens with absolutely no bezel, so that one screen blends seamlessly with the other screen when they're placed side by side. Neither of those technologies are available today, so all Sony's engineers could come up with was two screens, each with a modest 4 mm bezel that, when placed next to the other bezel, creates a whopping great 9 mm-wide black bar right in the middle of the display. (The other millimetre is the gap between the displays, which can be quite irritating if there's light behind the display, shining through.) Now, that wouldn't be completely fatal if the Tablet P were running an operating system that knew how to handle two screens with a black bar and a sliver of light in the middle of them. But the Tablet P is running Android, and neither Android nor most Android apps have a clue how to use the dual display. Some apps on the Tablet P, chiefly the ones Sony has rewritten specifically for the device, work quite well. The email app, for instance, uses one screen as a virtual keyboard, and the other screen as a display, when you're creating emails. When you're viewing emails, one screen is used to list the items in the inbox, and the other screen is used to preview the highlighted item. But trouble arises when you use apps other than the ones written to cope with the black bar. Most apps will just curl up into a ball and display only on one of the two screens. Neither of those screens is very large, so you end up with apps displaying little bigger than they would on a mobile phone. Worse yet, they're both very long and narrow, far more so than many apps seem able to cope with, and as a result many apps won't even fully utilise the one small screen they're on. Amazon's Kindle app, for instance, an app so well written that it can usually cope with any screen you throw at it, uses only 83 per cent of one screen, and zero per cent of the other. Almost 60 per cent of the Tablet P's display is left blank. It's such a pity, because a tablet that folds in two is such a good idea. Perhaps the best thing that can be said about the Tablet P is not that it means well, but that it's simply ahead of its time. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel -- It's always darkest just before you are eaten by a grue. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: XO-3 Announcement?
I wonder how a tablet really fits the Xo mission beyond PR? The G1G1, while flawed in a few ways, made an attempt at least to put a programmable machine in the hands of third world children and empower them to be content creators. A tablet is inherently a content consumer device, not a creator device. This is the secret to Apple's success with them. (They have been chasing this particular horse since the early Mac days. Mac was never supposed to be a creator device, that was the ill fated Lisa.) I cant imagine anyone typing much code on a touch screen keyboard. Is the goal of OLPC now to create more consumers?

What is its power consumption and charging requirements? Its still much too early to lay out exact claims for this. These are A1 prototypes. This is the stage where we start finding all the things that are using more power than we would like and try to reduce them. The exact size of the battery is also changing as we maximize the space in the battery cavities. We don't/won't start making any exact claims on power until it moves well into the B and C series builds. That said, a lot of the internals are almost identical to the 1.75 so the things I've previously said about 1.75 are going to be a good approximation of the XO-3. As John indicated the traditional display does consume more power than the Pixel-Qi. In case you missed my previous comment on 1.75 on devel@ the maximum runtime power draw of the 1.75 is 5W. (Not including the extra 5W you can draw from the USB port.) The power input front end of the XO-3 is currently identical to the XO-1.75 which matches the specifications of XO-1.5. 11V-25V input range and a maximum input rating of 25W. Unlike the XO-1.5 the XO-1.75 almost never gets to the 25W maximum because its runtime power is much lower. So the peak power draw only happens if its charging a very low battery. One difference between the XO-1.75 and XO-3 is that the XO-3 can _also_ be powered by USB On-The-Go (OTG). OTG has a strict 5V/7.5W power specification so charging via OTG will take longer. No. I've not yet measured how much longer. :) Sadly its not a nice linear thing that you can just do the math and figure out. There are many variables some of which will change with the next prototypes. Having a robust, wide voltage range, high power input is an important feature when using alternative power sources. Alternative power can be very unclean and very sporadic. You must be very forgiving on what you allow and when its available you want to maximize your input. I don't think any other tablet made so far would survive long term if you connected it directly up to an automotive 12V power system. Has it actually been demonstrated to be chargeable by solar panels, hand cranks and other alternative power sources? Especially ones not requiring systems which cost many times more than the price of the laptop, nor require someone with the green skin color of the XO to crank. This claim isn't really new. Evey XO generation we have made to date matches this claim. In each generation we made an improvement over the previous. Its always been possible to charge an XO from alternative power sources. There are sites in Rwanda, Peru, Haiti and the Solomon Islands (just to name a few) that are powered entirely by solar. These are using XO-1 and XO-1.5. Some of these use a more commercial type solar system and some just are just raw solar panels that connect directly to the XO. The XO-1 and XO-1.5 both had maximum runtime peak power draws in the 10W range. Running things like the camera activity which keeps the system busy would draw that power continuously. If you didn't have 10W of input you go backwards. Most people don't really realize how much work 10W of continuous power is. The physical size of a 10W solar panel isn't huge but its still pretty large and you need perfect solar conditions for that 10W. So what you really need is a 20W solar panel that so that a wide range of solar conditions still work. A 20W panel is pretty large and not something easy to lug around. The 1.75 (and tablet) have a runtime peak power draw in the 5W range and they idle even lower. So now devices that produce power in the 10W range can fully power the new XO devices in a variety of conditions. So you can envision taking an XO outside into the field connected to smaller solar panel (say 5-7W) and have a net power draw very close to zero. A 10W panel would almost certainly have a net draw of zero unless the solar conditions were really terrible. In my testing here in Boston I have powered a 1.75 directly (no battery) from the OLPC 10W panel in January sun. Here's a video Chris Ball and I shot Jan 9, 2012 showing a 1.75 completely powered

Re: SarynPaint: a Java program packaged for the OLPC

As long as it DOES still run Linux/Sugar then its up to us to make that compelling. I'm sure no third world country WANTS to spend another $7.00 a machine if there is no compelling reason to do so.

I mean we all mean well, but what if the project fails and developers drift away? There is a certain comfort for buying it in knowing that there is a big rich company behidn it. Even if that comfort is mostly illusory. (Microsoft HAS walked away from products in the past. Anyone else own a first gen WINCE device? I do. Nice paperweight.)

Particularly a shoestring, start from a new concept, non-profit, startup. However, the sales and distribution model of OLPC has set itself a high bar. Any single sales event that isn't in the six figure range is small potatoes in the current model of monolithic sales to national governments. And I'll stand with my assertion that if it takes saying that the XO does Windows to get those big sales, and get the little darlings into the hands of children, that it's a step that OLPC is correct in taking. It is a great start, and I dearly want it to continue. OLPC has certainly kickstarted a market that no one seemed to have realized the existence of three years ago -- laptops designed to meet the needs of children. The XO is a wonderful design and still the benchmark that these devices should be measured by. There is an underlying assertion in your post (and much of the press coverage of the Windows XP announcement) that the XO has not been selling well to date. I would assert that 600K units in the first 6 months is pretty good by most measures. It is a far cry from the 100M units that Nicholas predicted, but so what? It is a great start and there is every indication that laptop-for-learning programs on a variety of hardware platforms are springing up around the world--with or without Windows.

Java has a very X inspired window system. Retting that to run reliably on Windows has been a HUGE effort. The single biggest issue is this: Win32 is not a multi-threaded OS. What I mean by that is that, while you can throw off multipel user threads, it is *vital* that everything that actually calls into the windows kernel happen on a single thread-- the message pump thread. Doing anything else is either unstable or outright fails.

Re: Violent games on the OLPC Activities page
2008/1/17 Bennett Todd [EMAIL PROTECTED]: 2008-01-17T21:09:22 Ties Stuij: What's wrong with erring on the safe side with a controversial topic like video game violence in a learning setting like the OLPC project. [...] As was mentioned earlier in this thread, there are always gliding scales. The solution is not to just forget about them and just allow everything to keep things simple. To clarify my sentence above, I don't think the topic of violence in a learning setting is so controversial. Let's get a concrete definition of violence and I think the disagreement will fade right out. Would a game like pacman count? How about asteroids? Missile command? I'd probably feel good about a definition that could exclude missile command, that made me feel ill the first time I saw it. here here. And this was my first complaint. My second however though is more basic. Those attacking the messenger by accusing those of us who dont want to knee jerk censor violence with insensitivity could frankly use some sensitivity lessons themselves. Now, lets try to have a discussion not a propaganda war, okay? (Ad hominem attack is a PRIME element of propaganda.) The fact of the matter is that people all over the world have had traumatic experiences with all sorts of different things. I don't think it is or should be the mission of the OLPC to try to protect them from themselves and what they might decide to expose themselves to. Parents. Absolutely. No child of mine will be using an OLPC un-monitored. It doesn't take spending very long on the internet for one to realize there are all sorts of things on it a child shouldn't be exposed to at the wrong development point. Educators, again absolutely. If there is really such a culture wide trauma that a government wants to, well, then maybe that too. (Germany for instance until fairly recently in history outright outlawed any mention of the Nazis. In that case, sure, let them take an axe to the encyclopedias and whatever on the OLPCs they might chose to distribute.) But the OLPC organization is NONE of these and does ALL of these others a disservice when it choses to start playing in loco parentis. Once... whne dinosaurs roamed the earth, I was a college sophamore. And back then I believed in the sophomoric notion that laws should protect people from themselves. I've learned a lot better since then. Those who are willing to sacrifice freedom for safety, deserve neither. --Benjamin Franklin I missed Doom, didn't know anything about it. Sounds like a good candidate for putting in a separate place from educational games for young children. On a content level, sure. And its dfinitely not a young childrens activity. OTOH the DOOM engine represents some *extremely* clever graphics programming on limited hardware and as a programmign example is something kids can learn a lot from. My personal suggestion to the self-appointed censors is, if you don't like the content it ships with, go create some you DONT find objectionable to offer as an alternative. . And it's not so controversial politically, or socially. Doom no, it appears. But: Well Ill stand apart and say I think, given what we ship to other countries otu of Hollywood, its ABSURD to be worrying about the level of violence in DOOM. The only groups who would endorse a game like this that i can think of would be the arms lobby and some extreme Christian sects. Wrong. Im neither. It's folks in extreme [religion] sects, and other my beliefs win, agree or die types that worry me the most. Uh huh. And violence is inherently wrong and evil and we must protect other people's children from it is really just such a religious belief. I don't want to generalize but amongst a number of nay-sayers I sense a strong cencorship fear, while I just see a pragmatic decision to not include war material in an education project. War? Where is there a War in DOOM? I'd classify DOOM closer to Horror/Survival to be honest. And if were not going to include war material in an education project does that mean no history texts? Cause they are full of wars... Can we get a concrete definition of war material? It's not censorship, OLPC owns this microphone, they get to decide how it's used. I'm not saying Doom belongs on the same page as SimCity and Speak. Given your above description it shouldn't. I'm asking for _some_ kind of line between the two. The recent DVD release of the first season of Sesame Street warns that it isn't appropriate for young children. That creeps me out. How do we define the line between Doom and SpaceWars? I see the Activities page currently requests no strongly violent games. Is that clear enough? I really want to know why we are singling out strongly violent as if its the only message you should worry about your child getting. What about hate messages? Anti-gay messages? Pro-gay messages? Right-wing Political propaganda.
Re: Tricks to getting Java Frames working on the OLPC

It is impossible to provide a resolution other than the physical one on an LCD display without going through some kind of software scaling. Either we decide today that Sugar and its activities will only ever run on machines with 1200x900 displays, or we ask developers to make their activities scalable *somehow*. Which way seems more appealing to you? I think the answer will surprise you. As a game developer, its an easy choice FIX it at 12x9. Make other resolutions OLPC2 OLPC3, etc. Thats what any game developer would say. Xmame is not a good example because your looking at games desigend for much *lower* resolutions scaled up. Plus they were desgined for minimal CPUs so theres lots of processor with which to do it left over. 2D game developers' game play is integrally bound up in the screne real estate and how it is used. A change in play space of any kind can dramatically change the game. As I said, if the hardware can do the resolution, even if its by scaling, then thats likely acceptable. But a game developer wants to use what power you've given him or her on the OLPC for game play, not for scaling operations. These are just the realities of the industry and this kind of development. Do with them what you will. But the last time I was on a project where they told us no we don't need to do that because we aren't a game machine, we're an educational machine it was putting BLTers in the CD-I player.

Cross-develop on a more powerful platform, download the software to the XO, and test it. 2. Native develop and test on the XO itself. The XO as currently shipping does *not* contain a development tool set other than Python and Etoys, which is a version of Squeak, which is a Smalltalk IDE.

Re: Give One Get One laptop for software development
Eic looks really nice. I tooka first stab at installing it but (a) it has a LOt of dependancies that take up a lto of room and 9b) one of the dependnacies, QScintilla, doesn't seem to be available as a binary and I gacve up at that point. I might look at idle to see if its as bad... JK On Dec 23, 2007 4:24 PM, M.

The two main IDEs for Python are Eric and Idle (bonus points for knowing who Eric Idle is and what *other* group besides Monty Python he belonged to.) :) That said, IIRC a lot of the Python numeric code is bundled into the XO base, and a lot of *that* is already optimized. For example, the Atlas linear algebra library is on the XO (although it's the i386 version -- it's not yet optimized for the Geode). So I am guessing the original task -- elliptic curve cryptography -- could well be done efficiently on the XO in Python using pippy as the IDE. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel -- ~~ Microsoft help desk says: reply hazy, ask again later. ~~ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Fooling with Java
Thanks Guys. I decided to try something a bit lighter weight so i installed JEdit. I discovered that alt-p/alt-n and at elast for JEdit that works to get my editor window up front. Two oddities in mtachbook/java pairing still. (1) Although the system window is full screen its not resizing the Java pane to full screen but to more like 1/3 of the screen. I'm wondering if matchbook is somehow lying to Java about the native window size. I suspect I could hack that for a OLPC build since the screen size is a constant. (2) More importantly, pull down Java?Swing menus don't work right. When I cli k on the menu it appears but as soon as I release the button it disappears. The proper behavior, and what I see with this same jar file on other systems, is that the menu stays so you can select an entry. Second part of this is even if I try to do hold button and drag to select an entry , it doesn't highlight the entry right. Its worth noting that using KB short cuts for menus and entries DOES do the right thing on screen so it seems like its specific to the mouse interraction. Other then that, it seems to work great!

Re: Our Stories: Commercialization?
Well, FWI and realizing its not my projct so my opinion means nthoing... I've thought sicne i first fired up the emulator and got a good look at it that the OLPC project is probably missing a bet for funding. I'm willing to bet if it was licensed to someone like Mattel to sell in the first world, they could sell a ton at around $250, increase the volume to lower production costs, as well as funnel some of hte profits back into funding the third world efforts. But thats just my opinion. As far as the software goes, its all open source, right? As long as someone lives up to their obligations under the open source license I don't see anything wrong with them trying something commercial with it. *shrug* On Dec 22, 2007 6:25 PM, Tom Boonsiri [EMAIL PROTECTED] wrote: After reading the Bender update, I checked out Anna's recent effort (http://wiki.laptop.org/go/User:Anna_B) which seemed to be similar to Ian Daniher's Telehealth module effort and I noticed the following goal. -Van on commercializing Our Stories: would consumers pay for something like a virtual safari tour?

A recent news item stated that some countries that are heavily into hosting on line gambling casinos are asking the World Trade Organization to fine the USA because we have legislation to protect our citizens from on line gambling casinos. Don't entirely get your point here. FWIS, I think their complaint that we are acting in restraint of trade is an interesting one. The word protect is a pretty loaded term. The more politics neutral would be to say we illegalize gambling in this country (unless its owned and operated by the government, in which case not only is it legal but its legal to promote and advertise too, but thats another topic and not so politically neutral.) Its an intrresting, global world we live in, and as soon as trade began on the internet it became a very small one. We can't expect the rest of the world to live and play by our wants and prejudices any more then we would be comfortable with another nation saying we should live and play by theirs. But in a global world economy its not so easy to isolate ourselves, either. Interesting times 2.

Silly Question
I've been familairiazing myself wioth my OLPC but there are a few thinsg I havent figured out yet. (1) I have a 2 gig SD card in my card slot. I can see it in the journal, but I can't figure out how to use it for anything. In particular Id like to dowload stuff to it But when I download it goes to my journal, which I assume is hiding fiels somewhere in the main filesystem, yes? Is there a way to redirect downloads directly to the SD card? If not, is ther a way from the interface to move downlaods to it after they have been downloaded? (2) About those journal downloads... I thought I'd escape to the terminal and just move stufff from there if i had to, but I can't find them. The linux find command turns up nothing. Where are they stored?

Fooling with Java
Okay, I have a JDK installed and it seems to work. For grins i put netbeans on my USB stick and fired it up. It seems to be working however I get no main display. I do get pop up dialogs though. My suspicion is that Netbeans is asking the X wm for a Window and, sicne from what I cna see the window manager in the OLPC is windowless (one fullscreen root window only) it ends u pwitha null window and all the drawing goes down the bit bucket. Has anyone else played with this? If so does anyone know any magic to get it to use the root window for the app frame?

Re: sudo, not su.
Well, i understand. :) I was very surprised to find that by default root has no password on the OLPC! This seems a mite dangerous to me. I can just imagine OLPC viri springing up, propagtating through the mesh... I'd love to have a proper sudo on the thing. It would make me feel a lot mreo comfortable. On Dec 21, 2007 1:27 PM, C. Scott Ananian [EMAIL PROTECTED] wrote: I think people misunderstand the core problem: if root does not have a password, then *any activity on the system* can gain root privileges by su'ing to root. By restricting 'root login' to the olpc user via sudo, it becomes simple to restrict the activities which can gain root privileges, because our security system runs activities as their own UIDs. This is the key difference in using sudo, not whether the root account is 'well known', etc etc. --scott -- ( http://cscott.net/ ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel -- ~~ Microsoft help desk says: reply hazy, ask again later. ~~ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
