OLPC Project Interface Revealed

BogusToo writes to mention an EE Times article describing the interface for the OLPC project laptop. Using some fairly intuitive UI concepts (like simplified web browsers and a chat client), the Linux-based system attempts to do away with the kludgey parts of computer use. A video demo of the interface has been placed on YouTube. From the article: "Earlier postings around the Internet have also shown how the physical design of the laptop has changed, including the elimination of the much touted on-board hand crank that was supposed to power the cheap, lime green laptop. It's still there, reportedly, but has now been moved to the power adapter. The OLPC's produced earlier this week in Shanghai still need to go through loads of testing, such as knocking them off desks and dropping them in mud, as kids are wont to do. They may also be kicked around, like soccer balls, a popular sport in 99.9 percent of the world."

  1. Durable Laptop? by 0jjjjjjjjjj0 · · Score: 5, Interesting

    Having worked for a school, I know how durable these devices are going to have to be to withstand day-to-day use. The Compaq, Toshiba and NEC laptops of 10 years ago didn't take much more than a nudge to the back of the LCD to crack it or break the backlight, leaving the (admittedly rich) parents to fork out another $3,000 for a replacement unit, or $1,200 for the out-of-warranty repair.

    I hope that these computers end up being not just "cheap" but inexpensive to own, operate and repair. Insurance premiums on cars go up if the cost of parts/repair is high; the perceived value of this device changes in inverse proportion to this - why would a school/state/country buy thousands of them if the spare parts/repair cost is going to be high?

      My problem with the OLPC is related to the whole low power/low spec business. I keep hearing about how important it is to save memory, CPU and power on the machine. And yet... the GTK widget set that it uses has gotten slower and slower with every release since GTK 2.6.

      The GTK developers simply have no idea what they are doing. They ditched all the old X code and moved to Cairo which massively increased the RAM and CPU requirements for GTK apps... particularly hurting phone/PDA users like Nokia google for it... it's all there on the web). On top of the Cairo problems, they also made changes that sabotaged the performance of the various widgets. Basically, every version of GTK past 2.6 has been a fucking performance trainwreck, and the developers responsible (people like Owen Taylor) have just snuck off quietly and not taken responsiblity.

      I remember the GNOME mailing list discussions about adopting the then forthcoming GTK 2.8 -- adopting it meant taking a risk on GTK getting it RIGHT since they would be reliant on untested code. Lots of credulous developers said that they should adopt it because they had faith in the GTK developers not screwing them over. Mugs.

      Half a dozen versions later, and GTK still sucks fucking balls... and what's more, the OLPC suffers from it even worse because it is a low-performance system. Essentially... it runs like shit because of the GTK developers never having heard of stuff like optimization and benchmarking.

      It's marked insightful because it is true. After 2.6+ GTK is a dog. Cairo didn't not improve GTK one bit. Cairo can, and is, used separately from GTK. It's use within GTK has done nothing but turn it into a slug. Cairo might one day be a route to faster graphics in GTK... right now it's a millstone.

      The GTK developer, Owen Taylor, who ripped out all the X code was adamant that it would improve performance... he never ran a single benchmark before making that claim (ironic because he used to be rabid about demanding benchmarks from other people). He ran some later, and the performance penalty turned out to be disasterous. It was, however, too late by then, because the GNOME mugs had already committed to using 2.8.

      To say the Cairo switch was a complete fuck up is understating it. NO-ONE trusts anything the GTK developers say anymore.... and frankly, it's about time. It's been plain for a couple of years that none of them really have any idea what they are doing beyond adding and polishing new API. You might also be interested to know that various PDA manufacturers have forked GTK and ripped out Cairo and started optimising the rest themselves.
