Quite some years ago, we brought the #OLPC AKA the 100$ laptop to Rwanda [1].

@cryptobiont @jwildeboer,
Harv StaniΔ Staalman (one of the people who also worked on/with OLPC, IIRC) has been working with a bunch of other people on a somewhat similar laptop for the last few years: https://balthazar.spaceIβm looking forward to his presentation (and hopefully live demo) in a few weeks at @kiberpipa_cyberpipe

That's funny, the overly effusive Wikipedia page says it was, and is available as a snap-on accessory.So, like everything Nick Negroponte touches, it's just bullshit?

@RealGene I see you have a very negative opinion on the whole topic so I won't continue the discussion. I wanted to write a positive thread on the unexpected side effects we observed at the time. There are enough pages, videos and rants out there trying to dismiss the project as a whole.

(as expected, the naysayers and opponents are now in the comments trying to turn my thread into negativity. As always. It's the internet Well, I still hope I could give some of you some positive food for thought on unintended, but fascinating effects that we observed many years ago when the project started.) 8/8

@jwildeboer this is awesome. Are you aware of a similar mesh networking technology that's still available for current day computers? Sounds like this should get much more attention from the OS community.

@hook @cryptobiont @jwildeboer @kiberpipa_cyberpipe ooh that looks so cool and it's an @NGIZero funded project!

@maxheadroom It is based on the 802.11s standard which became integrated into 802.11 back in 2012. But the standard unfortunately was made ambiguous and complex to implement, IMHO. Because uncontrolled mesh networks are not really wanted by governments and other parties that prefer to be in control

@mripard The Raspberry Pi story is however one for a different post/thread, IMHO @Conan_Kudo

Maybe it didn't get widely deployed, but we had one. Perhaps it was a prototype.
Someone came up with the prank of handing out the laptops to all undergrads in the dev course with AC power supplies. All but one, that is. Then, to say oops, we've run out, and give that last student the hand crank.
I think a foot-powered charger was proposed but never made, though.

@idlestate Yes, they existed. But only as prototype. They were never part of an actual deployment, IIRC. The foot pedal thing also made it to prototype stage. What actually got used was a wind/solar, coupled with old car batteries, for example. And in many deployments stable power to charge was available. @RealGene

@Conan_Kudo @jwildeboer this was despite best efforts for the Open Technology group at Seneca College to build and maintain Fedora for the Raspberry Pi. Plenty support for the (then) Raspberry Pi foundation, little to none from Red Hat.

@scruss I am happy to discuss the Red Hat, Fedora and Raspberry Pi problem in a different thread. This one was supposed to be about the unintended side effects of deploying the OLPC back in 2008

@lobingera Cellular networks are so good that modern mobile phones use "Call via WLAN" @MonniauxD @simon

@jwildeboer @MonniauxD @simon Well, several things apply here:
a) Outdoor-to-indoor is hard
b) Many enterprise-WLANs are technically cellular systems (i.e. coverage and frequency planned)
c) My industry would really like to do indoor deployments also, as this is a very nice market, but landlords are hesitant (and WLAN exists)
d) I'm expecting more campus networks and then there will be not much difference between Telco and Local operator. -

@lobingera e) mobile prioviders make indoor repeaters prohibitively expensive and you often need separate ones per provider for reasons (even if the hardware they send is identical, just a different logo sticker @MonniauxD @simon

@jwildeboer @MonniauxD @simon At which price does "prohibitively" start for you?

@lobingera A few years ago we asked for our office in Munich. It started with a non-refundable fee of around 5000β¬ for measuring the office to identify the best placement of the repeaters. Then a lease/rebnt offering of around 150β¬/mo per repeater and another hefty sum for installing them. We said no. (This was at least 6 years ago, though) @MonniauxD @simon

@lobingera I am convinced it wasn't a serious offer. They simply didn't want to do it. And they succeeded @MonniauxD @simon

@jwildeboer @MonniauxD @simon I see.
I'm the research and technology guy and i cannot comment on product and/or service prices.
But i have seen recently how much effort you need to spend on proper measurement campains and ...
Central operated radio networks have a high efficiency (user-TP vs. carrier bandwidth) that ad-hoc deployments will not achieve.
But as many technologies, they are complementary. -

@lobingera An additional (and specific) factor is that our office building was originally built as the Infineon headquarter. They never moved in, though. But this means the building is well protected to avoid industrial espionage. One of the consequences of that is that mobile network reception is really bad. By design. Our WLAN works perfect while in the office, but once you step out of the office, it's gone @MonniauxD @simon
