Comment Inspired by Singapore (Score 1) 39

Malaysia is the close neighbor of Singapore, where news are either provided by state-owned companies, or censored as soon as anything displeasing the state is published. As a result the incumbent government never lost a vote, and it is perceived as uncorruptible even when the wife of the prime minister is appointed to rule those state-owned companies.

This can give some inspiration...

PRT is a 1960s invention, and it has never worked despite large research and development budgets. The only two working systems are so small and limited in scope that they cannot deliver the promises that make PRTs interesting.
  • - The Morgantown PRT is a 5 station peoplemover with 20-person cars and obsolete space-age electonics. It has only few stations, the cars are everything but personal, and it is closed on Sundays and during holidays, as it only serves the local university and its remote campus.
  • - ULTra in Heathrow is closer from the promise, but it only serves a parking lot and a single airport terminal. There are extension projects to reach other terminals and nearby hotels, but those are not currently planned or funded.

The French national library is doing it - they have all physical software releases since those started, and they have some technical folks that try to keep them readable and running. But they do not really have all the hardware means to do it, so they usually use emulators to run the software.

The difference is about Bluetooth & Bluetooth Smart (aka Low Energy). The second one is in fact a different protocol, once called Wibree, which uses some parts of the Bluetooth stack, but not a lot of it. While Bluetooth "Classic" already has network connectivity through PAN since a long time ago, Bluetooth Smart, introduced in the 4.0 revision of the specification, does not.

The main reason for this is that the maximum packet size in Bluetooth Smart is quite small (around 256 bytes in the original spec). The latest revision allows for higher MTUs, as well as an IPv6 header compression scheme called 6lowPAN, already developped for IEEE802.15, another low energy radio protocol.

Comment Re:Broadcom won't release documentation ever (Score 1) 165

From what I remember, what is missing in the OMAP/Sitara TRM is documentation about:
- The secure bootloader, so you cannot use secure mode: some features (precise, limited, useful only in very specific cases) in the CPU are blocked
- The GPU documentation, but I've never seen the SGX documentation in any SoC TRM, or for any other GPU

But you still have ~5000 pages of doc in the main TRM, plus all the erratas, which is much better than what many other manufacturers give you, even after signing a NDA.

Comment Re:US Airlines (Score 1) 240

Buying a flight (for example) from Paris to Tokyo is cheaper if changing planes in London, but it is also cheaper to fly from London to Tokyo through Paris, using exactly the same intercontinental flights.

The rationale is that by lowering the price of flights with two parts, you are poaching the clients of the local flag carrier, but with a substandard product due to the increased flight time and the inherent inconvenience. Conversely, incumbent flag carriers do not encounter a lot of concurrence on the direct routes, which means that the prices are geared towards what the customers can pay rather than what the flights cost.

For a reference point, the Bluecars used in a car-sharing service in Paris are for sale at about €12k, after a €7k subvention, but you need to pay an additional €80 a month for battery rental + battery exchange at 400,000 km. And it's a very spartan car, with 4 places but no trunk, clearly designed for city-only use.

You should look at LWN. It's a news site maintained by Jonathan Corbet, who co-authored the popular 'Linux Device Drivers' books for 2.4 and 2.6 kernels, and maintains a weekly newsletter about what currently happens in the Linux community. It also maintains archives, which gives it an index covering the widest range of topics in the Linux kernel.

You can read the 2.6 driver book on LWN as a starter, as there is no radical departure between Linux 3.x and the 2.6.x series. You can even grab an older copy/branch of the kernel like 2.6.32 and run it in a VM, as then there will be no difference between the source you use and what the existing books contain.
