Linux rides pillion on Mumbai city buses
,----[ Quote ]
| This triangle of devices in the bus uses ARM9 processors and runs embedded
| Linux using kernel 2.6. Having these Linux-embedded devices, says Satish
| Goriani, consultant to the technology provider Kaizen, drastically reduces
| the transaction time, and the inbuilt services in Linux, such as SSH, make it
| easy to manage them remotely. Forty buses are equipped in this way. The other
| 3,500 in the system use a more low-tech solution: a handheld device that the
| bus conductor uses to debit the smart card.
Embedded Linux has more friends than you may know

| Sony recently announced that one of its BRAVIA LCD TV factories will double
| production from 2 million TV sets per year to 4 million to meet growing
| demand in Europe. Sony has sold more than 20 million of these TVs, and
| they're all built with embedded Linux.
| So what? Embedded Linux is no surprise. Sony and tens of thousands of other
| companies, from huge to tiny, use embedded Linux every day to deliver
| successful products in every market. That is not news.
| Ten years ago, though, embedded Linux was a surprising-even shocking-idea to
| most people. Back in 1998, fresh from victory in the RTOS industry, I
| introduced the idea of building a software company to make Linux a suitable
| OS for developing smart devices. When I told people the idea, they gawked as
| if I was a few lines short of compilable code.
| "You want to build a company on software that's available for free?" I was
| asked. "Based on the gigantically bloated Unix OS? And with some oddball GPL
| license? How fast do you expect people to kick you out of their office?"
| Every market survey showed that the demand for embedded Linux was zero. When
| we released our first product, industry experts agreed that nobody needed it.
| Embedded Linux won't work because it is "too big, too slow, and not
| real-time," said the head of one RTOS company. The president of another
| derided embedded Linux as "a royal pain in the ass," so no developer would
| ever use it.
| I took heart from a quote attributed to Mohandas Gandhi: "First they ignore
| you. Then they laugh at you. Then they fight you. Then you win."
| Analyst firms don't agree on how many device engineers use embedded Linux,
| but they all say the number is substantial: 21% of developers use embedded
| Linux, according to last year's Embedded Systems Design survey; 36.7%,
| according to current research by Embedded Market Forecasters. This April, VDC
| reported that Linux is now the leading embedded OS. It shouldn't be
| surprising. After all, commercial Linux vendors succeed because they
| understand what design engineers are looking for.

| In a new whitepaper on Linux in the embedded market, VDC researchers cite the
| following reasons for Linux's popularity:
| Â* Â* * Licensing cost advantages
| Â* Â* * Flexibility of source code access
| Â* Â* * General familiarity
| Â* Â* * Maturing ecosystem of applications and tools
| Â* Â* * Growing developer experience with Linux as an embedded OS

| EDC noted that some 40 percent of the survey's 500 respondents were targeting
| embedded Linux.
| Also in the earlier reports, Andrews observed that the need for RTOS source
| code was "one of the reasons that proprietary RTOSes created in-house for a
| specific system have long been popular, and now it's a primary motivating
| factor in the adoption of Embedded Linux."
| The now completed survey results are said to include "expert analysis" from
| Ann Thryft, a 20-year industry veteran. The report includes chapters on
| platforms, processors, tools, languages, security, target devices, mobile
| development, and of course, Linux.
