Re:Can one develop software on the XO?
See this. It's pretty damn good.

Laptop power
I think my laptop would require a slightly larger weight to pull this off.
Not mine. 2 watts. 200mW with the backlight off (sunlight readable).

Re:Ah, RM "Proprietary is Never Good" Stallman...
But because it uses binary blobs for the driver and firmware, RMS fees it is hopelessly compromised?!
While the firmware may be binary blob, the driver is open-source. I wouldn't be surprised if this is the case for most hardware supported by Linux and BSD, so perhaps RMS is operating under the same misconception as you are? -
Re:Makes sense
When most people talk about closed-source code shipped on the XO, they talk specifically of the wireless driver, which is odd because this is actually open-source (git tree here).
What they are actually thinking of is the wireless firmware, which is a closed-source binary blob loaded onto the wireless hardware on system startup. My (admittedly limited) understanding of the situation is that while the driver runs on the main CPU, the firmware runs only on the wireless processor and thus can't tamper with (e.g.) operating system memory protection. So insisting on having the source to the wireless firmware is something like insisting having on the circuit diagram to your printer -- sure, the manufacturer could sneak in some malicious behavior, but the damage is limited to that device.
That said, the reason for the closed-source firmware appears to be that Marvell, the wireless manufacturer, licensed an embedded operating system to handle the low-level wireless functions, in order to get their product to market more quickly. They can't release the code due to licensing constraints, but they also appear to be willing to collaborate with developers to put together a free/libre replacement -- and there are some OLPC volunteers making progress on it. See this OLPC trac ticket for details. -

Re:Wha?
Well, I guess somebody better tell the OLPC project that they don't include GTK+ or PyGTK so they can fix their wiki.

They're working on a fully Free driver...http://wiki.laptop.org/go/Marvell_microkernel
The microkernel on the Marvell 88W8388 wireless chip is one of 2 to 4 pieces of non-Free user-modifiable software on the XO laptop. (the others being the EC firmware, and possibly the touchpad and keyboard firmware) This is where we explain what needs to be done to create a Free replacement, who is doing it, and what progress we have made.

Get it, gawk it, give it away
I did get my OLPC XO. I bought it the first day the you can order via the buy-one-get-one program. I received it some time back in late December. I showed it around the office, to some friends, and gave it a good shake down test. It was impressive and I thought was fairly well designed.
Then, I gave it away;
http://lists.laptop.org/pipermail/devel/2008-January/009361.html
I would encourage others who have received XOs and don't know what to do with them to do similar. Find a developer or someone who can really use it, and then give it away. Otherwise, contribute to the cause by helping with educational programs, improving the code, or writing documentation. Porting Doom, writing a new MP3 player, or bitching about performance is not helping.
It is not a general-use laptop. It's an educational tool. I don't think most Slashdot readers understand that. -

Thanks for providing a good example of the "mean spiritedness" that the previous poster referred to.
I (and all but one of my friends) got our OLPC laptops before Xmas without any delay or problems. My children (8 & 11) have been hacking at them ever since Xmas morning. My sample indicates that the OLPC project does a decent job of delivery - certainly better than most first-time-events in the field of international aid. Why are you criticizing, did somebody deliver your OLPC XO to an underserved child living in a ger in Mongolia instead of to your 1st world luxury condo?* You do realize the target children come first, right? What's your beef - and if you haven't got one, why do you feel the need to characterize OLPC as "incompetent"?

G2G0D1 donor, still waiting, but not mad.
I've shelled out $423.95 x 2 and am still waiting. And it's a shame that it's taking so long. But I'm happier that working-class kids in Mongolia (no, not "starving to death" people) have laptops, and I can wait. (I'm posting about it on THE INTERNET so clearly I'm not exactly struggling for 'net access.)
They had pro-bono donation of services from three (or more) different companies to handle ordering and distribution. Not having a logistics manager or dealing with the process openly *is* a shame. Lots of individuals unaffiliated have been volunteering their time, trying to help, but have been powerless to actually *do* anything, since the volunteers don't have access to all of the data sets.
Hopefully the next time they offer G1G1 they'll manage the order/delivery status themselves, they *should* be able to track each laptop from Quanta, to the shipping carrier, to the port, to FedEx. -
go to the source
The actually source of all these stories might be interesting to people, instead of articles about the source. Since when did people stop being able to read primary sources and start being able to only read "news" articles.

Re:Focus on what they do best?
Oddly, that is who OLPC partnered with to do G1G1, and who share the blame for the screwups.

Re:"designed to be hackable"?
You're right, it's kind of a stretch to call anything in that article hacking, but it is designed to be (software) hackable. Though, the line in voltmeter is unique in that the audio hardware was chosen to make that possible.
It's the only laptop I've ever heard of that uses Open Firmware, or any open source BIOS. There are even tutorials on hacking it in the wiki. Plus, most of the GUI and applications are written in Python and are designed to be relatively easy to modify.
The hardware itself is far from hackable though. There is very little, if anything, that can be modified inside the thing, even though it is easy to disassemble. I imagine its the result of making it as cheap and rugged as possible. -
How easy was it to make Opera work?One would think that Opera would be straight forward. After all, OLPC seems to already have solved the problem.
The Opera web browser and the Real Networks Helix(TM) platform have been ported to the laptop and are available for download but not part of the standard distribution.
http://wiki.laptop.org/go/Software_components
When we look at what the guys in tfa went through, we get the idea that they didn't know something the OLPC people knew.Next up we decided to pull Opera down onto the XO since the built-in browser gets the job done, but not quite the way we want. In order to do that we created a nested X server, since there's already one running that you don't want to disrupt. So, we basically ran one X server within another, and the nested server-software called Xephyr-ran outside of the other applications we had running. Doing this you can have a traditional Linux desktop running at the same time as your XO stuff, as long as your memory holds out.
Then they go through a screen full of stuff on the command line.By the way, one of the configuration changes that we showed in a picture above was to the dot pitch. By default Opera is basically unreadable in the X server, due to the XO's screen resolution.
And finally they get it working. -
Re:Sad
Apparently, there's been several issues with G1G1 fulfillment. They expected to have shipped every laptop by now, but discovered at least 5,000 orders that have fallen through the cracks. Those will be sent tomorrow, if possible. More information is at http://wiki.laptop.org/go/G1G1_Fulfillment_Information

Re:Oh no!
You're right that Unix-style permissions aren't all that great. What's cool though is that now there are flavors of Linux that allow permissions by *application* instead of just by user. Per app permissions are much better, because it means you can say that MailAttachmentApp is not allowed to erase anything or that DriveByDownloadApp isn't allowed to use your webcam. See the OLPC project's security page. They've incorporated this kind of security into their machine. Sure, it's still not perfect or a guaranty that you won't lose data -- but it's better than any current system.

Re:What the fuck are you talking about?
Of course it's possible to rewrite the simulator in any other language. It's just a question of how much work would it be, and how sure you would be that it did the same thing.
It was comparatively little work to rewrite C code in C++, because that's exactly what C++ was designed to do: take old C code with global variables and functions, and encapsulate it in a class with a well defined interface. Because C++ has the implicit this parameter to each member function, and it's not necessary to explicitly specify this when accessing member variables and methods, you don't have to change C code very much to translate it to C++. A different language with explicit this (or self) would require meticulously changing every line of code, and that would be orders of magnitude more work.
The first step to translating a big pile of C code to another higher level language is understanding and strictly defining what it does. Translating it to C++ is the first step in that process. That gives the code a lot more structure and coherence, without disrupting how it works.
The next step is to clean it up and toss out everything that isn't relevent -- all the old user interface and operating system hacks that no longer are necessary and have nothing to do with the simulator.
Once you have a clean core of code that verifyable works with well defined interfaces and without any irrelavent crap in it, it's much easier to start rewriting it in other languages like Python or Lua. (I would NOT suggest using Perl, though. That is a horrible, dead end language, antithetical to teaching kids how to program.)
Alan Kay and I have been having an interesting discussion about how to rewrite SimCity in much higher level languages than Python and Perl, specifically visual programming languages like eToys, Star Logo, Max/MSP, KidSim (Stagecraft Creator), Bounce (Body Electric), SimAntics, etc, along the lines of Robot Odyssey.
What we want to do is to open up SimCity to the Python scripting language as a first step, and then write a high level visual programming language in Python, easy enough for kids to use, but powerful enough for real programming.

Re:US loves wasting money
If you really believe that the XO is the best thing since sliced bread then why is it that companies arent lining up to buy them for their employees? If it really was the best deal wouldnt everyone want them?
The target for the OLPC is education for children. It's not available for general sale so companies don't have anywhere to line up even if they wanted to.
The OLPC is a non-profit organization that is able to get non-profit prices from the manufacturer. They avoid much of the cost with a commercial laptop by doing bulk sales with the local ministries of education who in turn take care of the distribution. Much of the price for commercial machines is due to sales/marketing/distribution costs.
Also note that it is not just a laptop project but an educational project. There's some more infrastructure involved such as the XS school server.
Over time I expect to see variants of the OLPC-XO laptop itself as well as commercial alternatives available using some of the interesting technologies introduced such as:
- Bitfrost computer security
- Per laptop activation/developer keys for firmware security
- Dual mode display
The XO has only just started to be mass-produced so be a bit patient and even though it may not have OLPC in its name there will be some products available which will contain some OLPC based innovation within them.

Re:Negroponte is helping US!
Dear Molly,
You may be a bit_itch, but you ain't never been goth anything.
You said it best; "Look at me, I'm an attention whore!" yes, you are indeed a dogma/money slut.
Do you work for Int$l, M$, and/or are you just another of the mighty clueless?
I have two OLPC, they work great across my *.11n. They ain't my box-beast, but for school kids ... they are extremely well designed and thought-out.
The cost faux-truth you spun like a corporate politician/tele-clergy.
The OLPC project originally aimed for a price of 100 United States dollars. The USD exchange rate is down globally. A $200 laptop, considering school book prices/revisionist content spin being feed to school children, poor quality education ... we are all better off with more education tools in the hands of all students. No child left behind is more likely to succeed with OLPC then with test-teaching.
Kids can teach each other more in a shorter amount of time then most adults or any politician can perceive as possible for kids learning collaboratively in a community of their peers.

Our Failure, as a nation, is not an option for US children!
How many wannabe POTUS have committed to impeach Bush for crimes and treason, or moved to prosecute scavenger-bank mortgage loan-shark CEOs and personnel, attempted to evict religion from politics/government, demand fair and honest election machines/receipts .... There is not one of the wannabe POTUS I can trust to work for a better stronger US, eliminate Citizen/personal income tax ... replaced by a fair-flat business sales tax at each point of sale in the USA ... the customer buyer still pays/buys, but no more annual tax filling for the private citizens, and the tax rate floats annually to balance the budget; So, everyone rich and poor pay their fair share. Skipping a middle man point of sale ... tax evasion crime, unless the appropriate greater-tax portion is paid at point of sale. No wannabe POTUS talks about the Corporate (oil, tobacco, ADM ...) welfare, DMCA/RIAA... IPR laws, legacy or innovative economic models ... I expect the wannabe POTUS will prove to be great friends of the Corporate States America just like Nazi-Lover Bush.
Just one wannabe POTUS really for US and The USA Constitution (in the batch) ... I would vote again ... for the patriotic honorable loser.

Re:Cue the OLPC griefers

Please give us $50 PCs soon
I'm sure most people working at Intel or Microsoft probably are cool.. Such as the people who probably worked hard for many months making an Intel chip work inside of an Intel version of the XO and having all their work scrapped by a strategical decision at the managment. Or the Microsoft employees who have worked over a year on the XO version of Windows XP. Anyways, I've suggested OLPC to release many more videos on the Internet to let people know what's going on and to let people know the truth while there are all these positive and sometimes negative stories going around on all the big and small media. OLPC is a huge hope for many people following this industry and in my opinion there should be a bit more blogging and video-blogging going on from within, more then http://planet.laptop.org/ I do what I can as an independent fan at http://olpc.tv/

OLPCnews.com much worse than Mike Rowe SoftIf that RedHat employee runs the blog "microsoftnews.com", using the logo colours of Microsoft, and gives the impression of being "stern but fair" in their (manifold) criticism, then I'd say you have a point.
I haven't read olpcnews.com often but I thought it was VERY well written. It took me over 15 minutes to get a nagging feeling that something was very wrong with what I read (and I hadn't heard of the site before, I found it while googling for OLPC; olpcnews.com sounded more appropriate than "laptop.org"). I think it is quite difficult to impart on your readership the feeling that a project is well-meaning but delusional ("trust me, I've worked in the third world" - ffs).
What annoys me personally is to find this anti-OLPC criticism site BEFORE finding the project website; it really doesn't bother me too much that this Wayan person tries to wipe the floor with the OLPC project; in case it's fair criticism it can be used to improve and strengthen the project, and else, well everyone is entitled to their own opinion.
But I think it's really bad that he chose to deck out the website in OLPC-XO green and white and doesn't have a clear disclaimer saying he's working for a direct competitor, because it may confuse some of the readers (say, oh, ministers of education) that this is a more or less independent source of information.
BTW if you made an anti-Microsoft site microsoftnews.com, using Microsoft's logos and colour schemes, run by a RedHat employee, I think you'd get sued by Microsoft for trademark infringement (Mike Rowe Soft, anyone?). But maybe I've seen too many American lawyer drama's.
P.S. it seems microsoftnews.com is still available, I just checked to see if it was a RedHat-run covert operation

Re:I am going to go out on a limb here
this blog never really had that big of a following
If it doesn't have much of a following its probably due to the obvious bias of the site. I don't recall the first time I read olpc news and how I got there but it was obvious from the start that it wasn't really an olpc news site but rather was simply an attack site spreading the same disinformation we see posted to message boards.
The olpc news blog attacked the educational objectives of the project from the start, not by critically assessing the years of research and study that went into the plan rather, by completely ignoring not just the research and study but even the advertised objectives and methods written in plain english on the loptop.org web site. How many times does it have to be explained to these people that its not a laptop project dumping laptops on starving third world children, its about the educational concept of constructionism.
It even continues to this day where he posts "news" that there is no news showing that the kids who have so far received laptops are learning when again if he has been following the real news, you know, journalists and reporters actually out in the field finding out for themselves, the educational benefits are beginning to demonstrate themselves in small ways just as they did in the research.
And even if the blog is not closely followed, this guy is being interviewed and quoted all over the radio, even by NPR, as a source for OLPC news. That would be news about OLPC, not the website olpcnews which is a misnomer. Its disgraceful. Even though I stopped reading the guys web site I still had to listen to his crap on the radio when ever the OLPC project comes up in the real news.
Even though there is an obvious conflict of interest, and his site seems to be very biased, I can still see the possibility that he was just creating a blog about something he was interested in. I don't believe that the XO and Classmate were originally competing products as the target kids and communities for the OLPC educational program were outside the realm of Intel's existing educational assistance programs. The problem is that marketing PR, and in the case of Microsoft politics concerning open source software, drove them to "compete" in the OLPC "market" when in fact there is no market, its a charitable non-profit cause. As things were getting ugly in the media between Intel and OLPC he really should have disclosed the conflict of interest that arose. -

EeePC is no substitute: too small for learners
Whilst over the years computers have grown more compact, and display sizes are varied without argument, there remains widespread majority preference for one aspect: the 'normal' proportions of a keyboard.
The squashed keyboards/keypads on mobile/handheld devices and on Eee PC may be useful, but they're not as useful, easy or widely-appreciated as a normal-sized keyboard.
For devices with squashed or no keyboards: there exist, as peripherals, plenty of normal-size projected or peripheral foldaway/fabric keyboards.
For devices with normal keyboards: I know no-one who prefers to use a sqaushed peripheral alternative (though there are probably very rare cases when people do so).
I guess that normal-sized keyboards are ergonomcally good and it does seem that XO fits.
Why use an inferior tool (squashed keyboard) for learning --which is what the XO and OLPC are all about -- if it's near-inevitable that sooner or later, you'll require additional learning -- to use a device that truly fits one's fingers whilst typing)? As you learn through doing so I can't view Eee PC as an ideal device for learners.
Don't misunderstand me: I'm not disrespecting the Eee PC in itself. A colleague has one, and he loves it, and I realise its usefulness, but the keyboard is peculiarly small and I can't view Eee PC hardware as a recommended substitute for XO.
Best,
Graham -

Not just Linux...
As long as we're questioning the educational value of a "standard" OS, let's question the educational value of "standard" end-user software. Face it, 10 year olds aren't very interested in playing with a word processor or spreadsheet. How about something that will actually engage and challenge them? Even if they don't go for the XO, schools should consider installing some of the software from that system. Which is not terribly tied to the OLPC project, or even to Linux. OLPC's innovative user interface also deserves a close look.

Re:It might not be as bad as you think, therotical
An average laptop consumes about 50 watts.
I don't think so. That's a page off the OLPC wiki, it says that laptops average about 20 watts idle. This is closer to my experience.
On an IBM T-40, the power measuring tool that comes with the computer (software) shows the laptop will use between 16 and 18 watts on lowest power consumption and up to about 25 with everything maxed and some peripherals plugged in (wi-fi, usb-powered hard drive).
On a friend's macbook pro: I think the system normally runs around 20 watts, and will use 11-12 W minimum and 40 to 50 max. This is a modern model: the latest, highest end one released, not including these new ones that will be coming out in a few days.
Here's another link. They estimate laptops average 10 watts, and I suppose your laptop would draw less ehile you were pedaling their generator (the laptop being idle).
I just want to tell everyone that 50 W is a bad number to assume for laptops, and 20 W is much better, and google is your friend.

Re:Prefer a $200 laptopHopefully soon the OLPC will be available to buy here in the UK. It seems to fill a niche of being ultraportable (7 inch screen), good battery life (9-10 hours, 2-3W consumption, long life NiMH battery) and low cost ($200, dropping towards $100 in the future perhaps).
They're lovely machines, to be sure. I was given a late prototype to test back in August, and when my normal laptop ceased to function, I started using the OLPC exclusively. I found it was dead easy to learn the interface, and for casual purposes the beta interface was slow but useable.
The keyboard, however, is designed to by suitable for children - or, more to the point unsuitable for adults. The idea is to make it less likely that dad (or big brother) will come home, crack open a beer and say, "C'mere kid, gimme the laptop for a few minutes..." and then spend the rest of the evening using it to browse pr0n while the child sits helplessly by.
In short, the XO is a close-to-ideal laptop in so many ways, but it's been designed to be most useful for children only. You may find it possible to accommodate yourself to this (I did), but don't expect too much assistance from the OLPC project in this regard.

Re:Windows kills the OLPC
The goal of the OLPC project is not "to educate children about how computers work". There seem to be some delusional folks in our community who think that the project is trying to breed the next generation of Linux-hackers and open source developers. It's not about teaching computer science, it's not about developing Open Office plugins and it's not about learning to write bug-free code. It's about providing an educational tool to give children a "window on the world, as well as a highly programmable tool for exploring it" and that's very different from what some people think it is. Perhaps you should read about the project's mission from their site: http://laptop.org/vision/mission/ One of the most important lines they have in there is that the "OLPC is not, at heart, a technology program".

Re:Emulation is your friend
Something Pez forgot to mention is that you can emulate an XO relatively painlessly. There is even a premade image file that is available that you can drop into say QEMU and see what it's all about.
A few caveats: Use something with virtualization which unfortunately means x86. Trying to run this emulated on a high end PowerPC system was saddening. Yes it is only a 433MHz target, but 433MHz is pretty high when you think about it. The other thing to keep in mind is that the premade image wants to change the display to about 1024x768 instead of the XO native 1200x900. The Sugar manager seems to be fine with it but most activities (XO apps) will not display properly. -
Mary Lou Jepsen is doing it for him
Maybe Negroponte should just pull off the gloves and make a deal with Wal-Mart and Costco to carry
OLPC's. Use the profits to donate machines to developing nations. Or use the profits to cut schools in
this country a big discount. If Intel and MS want a war, give them a war.

Don't get mad, get even!
Reading this article made my blood boil. Intel very clearly acted in bad faith, and their actions against OLPC will no doubt result in poor kids being deprived of access to technology. Immediately, my thoughts turned to the business I've given Intel and whether I could ever buy from them again.
But my second, more constructive thought was "what can I do to help OLPC?" and I easily found two great answers.
1. Donate. For just $200, you can give an XO laptop to a child in a developing nation. It immediately makes a difference in the life of one child, and it's an opportunity for the XO to prove itself. Our donations no doubt will drive future sales for OLPC. Donations are entirely tax-deductible (Question: does anyone know they're tax-deductible for Canadians?).
2. Develop. If you're a programmer, you can donate some of your time and work on an XO Activity. There's already a pretty impressive array of available software, but there's lots of room for work, and this is one way that OLPC can really differentiate itself. Think about it: thousands of passionate hackers contributing quality free software, all targeted at this machine. That's something that Intel and Microsoft will never be able to compete with because no one else is ever going to be passionate about Classmate & Windows.

Power consumption
How about electricity for every child?
See the power consumption data for the laptop. It runs a 2W (versus 10-45W for a normal laptop) in normal mode and down to 0.3W-0.8W when in "e-book" mode. Running that against the battery data which reports 16.5-22Watt-hours gives a normal-usage of 8 to 11 hours, or e-book usage for 20-73 hours.
You can also get a pull-string charger for when there is no supply.
This isn't comparable to companies supplying old hardware as a goodwill gesture: the OLPC has been thought through and planned for these situations from the beginning. -
Re:The NYT headline is a bit inflammatory...It seems you are the one full of it and you don't even know it.
The OLPC is a non-profit organization, I find it hard to believe you don't understand what that means. Let me give you a hint, non-profit means NO PROFIT? Many people and organizations are donating time, cash, and technology to OLPC which they will write off on their taxes as donations to a charitable organization, it is a non-profit. Obviously OLPC needs capital to continue but its not the same motivation or need as a profit driven corporation. Negroponte had a good explanation when queried about this latest incident...We're like the World Food Program and they're McDonald's. They can't compete. They are both food organizations but for completely different purposes. If the Classmate were in the hands of every single child in the world, that would be pretty good. Could it have better power charcteristics, a better display, etc.? Sure, that would be good. But I don't care if kids get the XO so much as that they get laptops.
And it is outrageous that anyone continues to this day to push the argument that somehow OLPC's objectives are questionable because starving children need drinking water or whatever other basic need people decide to throw in the argument. If you'd bother to research where these laptops are going and the years of research completed by the OLPC people to achieve their objective, which by the way is not simply about giving laptops to kids, you would realize that the kids who are receiving OLPC laptops HAVE DRINKING WATER. There are many poor children in the world who have food, have drinking water, have a place to live, and in many cases are even receiving an education, who can benefit from the theories of constructionism first developed by Papert.
If your going to post comments attacking OLPC at the very least you should go to laptop.org, click on the 1, and read about the projects vision. -
Intel is all kinds of Wrong.I just wrote up an article on this story yesterday.
Expect to hear all the usual "Intel is a business" bullsh*t that always comes up.
What has to be remembered is that Google is a business, Red Hat is a business, News Corp is a business too, and yet none of them actively tried to sabotage the OLPC foundation they had contracted to be a part of. Somehow they can justify their participation to the stockholders, but Intel can't? Intel was acting competitively before they joined the OLPC foundation in July of last year. After that time they continued to do so, only now they had access to a lot more information about XO potential buyers. Their behavior was despicable and only further enforces my decision long ago to buy AMD processors exclusively.
Adding insult to injury, Intel holds a press conference call announcing the decision to split, without informing the OLPC board. Read through the stories from last Thursday. The olpc foundation had no response because they were shocked.
They recovered nicely in my view with this official response. http://wiki.laptop.org/go/Intel#INTEL_RESIGNS_FROM_OLPC
I hope Negroponte & company sues for breach of contract.

Re:I have one of these...
I agree with all of your judgments, and am relieved to see I'm not alone.
The UI is not awful, and is good enough, and it was probably correct to think it through from scratch instead of trying to riff on the Alto/Star/Lisa/Mac/Windows. But it still tastes to me like other not-so-good UIs, in which the designer and people that can be coaxed into the same mindspace can be convinced that it's better than it is.
I read the human interface guidelines and I'm not convinced. I've often talked to people who have believed their UI was easy to use because "you always do thus-and-such to achieve this-and-that, and the frammises are always on the left edge, and you ferthboinder toward the top to glorp persistent quibinicks..."
One of the things that was fascinating about the Mac in 1984, which I approached with virtually no previous experience, was that you could intuit it and use it without ever formulating or deducing the consistent left-brained rules by which it operated. For about three days I used it effectively without understanding it at all. I wanted to achieve something, I took a wild guess as to what might work, and it usually did.
I don't feel that way about Sugar, although maybe my brain has just ossified.
If the Journal functioned the way it's supposed to, I don't understand why it, rather than the "home view," isn't the center of the user experience, and the thing you boot into. Seems to me that you'd more often be returning to an old activity than starting a new one.
I "get" the idea of a linear, chronological arrangement of activities rather than a hierarchical tree of documents, but I don't understand how you navigate that arrangement unless you are punctilious about giving each saved activity a good name, and clever at naming them in such a way that you can search for them by typing search strings (which I think only search the name of the journal entry, not the content of the saved activity). -
Re:It Makes SenseFurther, the announcement on the OLPC news page suggests the parting is entirely amicable:
2. Mary Lou Jepsen: Mary Lou's last day at OLPC is December 31. She will be continuing to consult with us on a number of different fronts as she chases after her next miracle in display technology. Mary Lou was OLPC employee Number One, both in terms of when she joined the organization and in terms of the breadth and depth of her contributions. Thank you and best of luck with your adventures in a new role and new year.
There is no suggestion that Jepsen leaving will deprive the OLPC of anything but her immediate attention. The article summary puts a misleadingly negative spin on an otherwise non-event -- especially by implying that the planned end of the G1G1 program ("commercial sales"?!) is in any way related to her leaving or that it signals any sort of setback. -
Re:Is it just me?
Heh. There should be a Star in the toolbar towards the right (try all the tabs), and it will add a Boomark, and the bottom toolbar to hold it.
The trick is that you need to rename your Browser activity session, and resume it from Journal to see the Bookmarks again.
