Off Topic: linking (0, Interesting)

Anonymous Coward | more than 11 years ago | (#5043555)

When you write with the link "this technical article" those 3 words will be used to describe the link to a blind person (because listening is much slower than reading common use involves jumping around the page between links and headings and having them read out of context). Instead a better link would have been,


"Nicholas McGuire examines the requirements of embedded systems and suggests some key issues that need to be addressed in order to improve Linux for use in embedded applications [slashdot.org] , in this technical article at LinuxDevices.com,"

tech question then (1)

--a question then. How would a blind person know whatever the link text is actually IS a link? I've never used software for that purpose, is there an audio cue, or does the software just tell you in words like "the following is a link" to "link over", or something like that?

Re:tech question then (1, Funny)

What I usually find is that when the web client reads the link, it reads it out in a blue, underlined, voice.

Quite obvious really, when you come to think about it.

Ugh. Poor writing style... (1)

I couldn't stomach the whole article. It doesn't look like an editor went anywhere near it. And what's the deal with his footnotes/references? The 'HT' in HTTP and HTML stands for what again? Is it too much to ask for those references to really go somewhere?

Embedded linux? Why bother (-1, Flamebait)

Anonymous Coward | more than 11 years ago | (#5045542)

Open-source software is the last thing you need on an embedded device. Have you ever tried to run Mozilla? It takes 10 minutes to load, even on the latest Pentium IV, and can't even render many simple pages like Hotmail correctly. Or how about GNU emacs? It has a built in scripting language and email client, but doesn't even have a proper built-in spell checker. Linux is just the same. Its a poor imitation of Unix, which has been obsolete ever since VMS came out in 1977. Its also slow and bloated, with all the cruft needed to maintain backwards compatibility with obsolete 1960s software. Thats not what you want on an embedded platform: you need a low profile, an integrated development platform, and real-time performance. Only closed-source platforms like vxWorks, QNX, and Windows CE fit the bill.

Unfortunate, but currently true. I've been toying with the idea of writing a new open source RTOS based on modern operating system concepts. I wonder what the response to such a beast would be.

Such as RTEMS? [rtems.com]
