However, unlike a Braille readout which gives tactile information (through the reader's hands), synthetic voice cannot easily accomodate to the reader's habits and reading speed. "Scanning text" is not possible as the generated voiced text is played in "linear time", which means you cannot easily skip forward and backward, re-read a certain passage, and you basically do not come down to the "letter level", you only have a "word level". While this has benefits in "unconcentrated reading" (e. g. reading an article or literature", it can be problematic with scientific or technical text where a (healthy) reader would let his eyes "jump" within the text stream. > One can learn to type and touch-typing was tought in > schools for the blind for scores of years before computers ever > even came on the scene.

So, a person who is blind needs to > know how to type. A good keyboard can help here. Keep in mind that a keyboard, being a means of input, provides tactile feedback as output. So without any visual confirmation you can detect when you made a typing error, activating a "motor program" to correct it on the fly. At this point, I typically recommend using an IBM Model M keyboard. But the Sun USB Type 7 is also good, as it provides programmable keys for volume control, application interaction and Braille readout control. (I use those keys primarily for dealing with the window manager - no need to use the eyes!) > None of these screen readers are perfect, but most > computer users who are blind end up being reasonably happy with > one of them. Especially in combination with web browsers, they are prone to fail. Where there's no text (as content) in a web page, there's nothing to read to the user. The use of the HTML tags alt= and longdesc= is a long forgotten art, and when "Flash" enters the scene to replace few lines of HTML (as for links or simple text), there's no easy way to determine _what_ currently is on the screen. > There are also Braille displays which some people use > but they are extremely costly. Sadly, that is correct. In my opinion this is because they are a niche market. When purchasing one, you have to pay attention to if it can capture "normal text screen" content. How is it attached to the computer? Does it require proprietary drivers? How long can it be used before an OS revision breaks the drivers? Those Braille readouts can be placed infront of the keyboard, the primary means of input. Reading and writing isn't far away from each other (finger travelling distance). Classic Braille readouts didn't seem to require any driver. I've seen such devices in the past. A slider on the side simply defined the row of text which was then displayed on the readout - one out of 25. I think it was plugged into the VGA chain (PC -> readout -> screen), but I'm not that familiar with this technology; I've seen it on a DOS PC. However, as FreeBSD's default screen mode is 80x25 text mode, it should be possible to use such a device. Maybe it's possible to get a used one for cheap... > I mentioned the speech recognition systems.

To create a custom install CD? You might find it better to build your .iso or memstick images from the system sources. See release(7). The trick seems to be to make the 'system' target of the /usr/src/release/Makefile which will install the system into a chroot. You should then be able to edit files under that chroot. Then just 'make release.iso' or 'make memstick' to create an installer image. Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil.

Our company is facing a jump from FreeBSD-4.11 to FreeBSD-8.1 later this year (in a few months). The challenge is recognized as: 1. Upgrade 3,000+ systems in a matter of 60-90 days. 2. Many of those systems need to be upgraded remotely where no technical staff exists (e.g. India, Philippines, Canada, etc.) 3. The remote upgrade must be done via SSH and NFS 4. Machines being upgraded must reboot and come back onto the network without local technical assistance The technique that I developed to accomplish this is a shell script weighing in at [currently] 1954 lines of code. In addition to the 1954 lines of code, there are another 631 lines of code dedicated to specific migrations that have to be performed specific to (say) jumping from 4.11 to 8.1 (e.g., you should remove the "nodev" option from your NFS mounts in /etc/fstab, among other things). On top of THAT, there's another 8778 lines of code dedicated to "cruft removal" (lists of files/directories that are unique to either the source-binary distro or the destination-binary distro; depending on the direction of migration). I will be releasing the full script soon (in a couple weeks) and even though it's not specifically targeted to your migration path (6.3 to 9.0), it can be learning-tool to illustrate exactly HOW you can go about making that binary migration a reality. Fortunately, it's very easy for me to provide explicit instructions on how exactly we jump from 4.11 to 8.1, or 8.1 back to 4.11, or even from 8.1 i386 to 8.1 amd64 (and back) ... the script that I've written takes a "-nv" syntax which means "don't actually do anything, but show me the explicit commands that I can execute by-hand to migrate from one OS to the next as an in-place migration" which has the following output: NOTE: The output below is a sample migration from 4.11 to 8.1-amd64 WARNING: This is not intended to be a full solution provided to the OP but rather a conversation-starter that should illustrate not only how HARD and/or DIFFICULT it is to do what the OP asked, but also to show how it IS POSSIBLE to achieve. WARNING: Also, it's worth noting that this procedure will NOT work to jump to "9.x" because the binary distribution sets from 9.0 and higher are in a different format. You can work around this by adjusting for this fact -- replacing syntax such as "cat base/base.?? | tar ..." to simply "cat base.txz | tar ..."

Re: Off-Topic: Computing for the Blind
There may be several people on this list who are blind, meaning no usable vision to see a screen. I definitely fit that description so I will gladly try to answer questions which breaks my usual practice here of asking beginner-level questions even though I have been using FreeBSD for almost ten years. The easiest and most economical interface for computer users who are blind is spoken speach. I am not talking about speech recognition where you speak to the computer and it does things, but speech synthesis where the computer runs an application to read what is on the screen back to the person using the system. One can learn to type and touch-typing was tought in schools for the blind for scores of years before computers ever even came on the scene. We pounded on typewriters and our poor suffering typing teachers were the feedback mechanisms that told us how we were doing. So, a person who is blind needs to know how to type. Almost every operating system has a screen reading program or several that one can install that reads the screen back to you. There is a good screen reader for the Macintosh which is included on every single Mac that runs OSX10.X. I like it and the Mac's do run a customized version of BSD unix. The screen reader for the Mac is called voiceover and you can activate it by Command-F5 and then Command-F5 again to turn it off. The only drawback to voiceover is that for those of us who do a lot of tinkering and compiling of source code on unix systems, the screen reader makes listening to the stream of consciousness almost useless because it resets itself each time new output is detected. There is also a lot of really neat things going on in Linux. We have Orca which is the GUI environment and some very good software speech synthesizers for both the GUI and the command line worlds. They tend to handle bursty output from compilers and log tailings better than voiceover but you find that both Mac and Linux screen readers shine in some things and don't do so well in others so there is no clear winner. Finally, there is the Windows world. Microsoft may be actually trying to improve their narrator application to where it is a serious screen reader, but up to now, there is one free screen reader that some people like to use plus several commercial applications that cost an arm and a leg and are always one upgrade away from being snuffed out and causing their owners much grief. None of these screen readers are perfect, but most computer users who are blind end up being reasonably happy with one of them. I personally like Linux and the Mac because there is no additional charge to install the screen readers and they generally won't let you down. There are also Braille displays which some people use but they are extremely costly. I mentioned the speech recognition systems. Many of those actually present problems for those who are blind because you need to train them on your speech and the feedback is graphical so a good old keyboard is still the best input device. So as not to get totally off topic, I haven't heard of any of the Linux screen readers being ported to FreeBSD. That could be a problem for some people and not an issue at all for others. Right now, I am typing on a Linux computer running a software speech engine and I am editing this message on a FreeBSD9.0 system via ssh and using vi on the actual message file. It works great. If that Raspberry Pie Linux system turns out to be able to support one of the Linux screen readers, we're talking about a talking terminal for less than 100 US Dollars. We'll just have to see what happens.

I am going to be facing the same issue in a few months. My experiences with the serial console are that it is great for correcting small issues, trying to use it for initial configuration is not going to be real easy. I would like to be able to build a custom CD for that specific machine that doesn't need any operator input. They just install it and boot the machine. It would need to format the disk and do the complete installation (base and uniquely configured ports etc.). Is that possible?___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Remote System Builds
Is there yet any way to remotely rebuild a FreeBSD system? I have two FreeBSD systems on two remote campuses that presently run FreeBSD6.3. They need to be running FreeBSD9.0 and I don't really care how I get there as long as it can be done over the network. If we were physically there, I would put a CDROM in and blow them away since it is such a large jump. I can have staff members there install CDROM's that were remastered to use the serial console, but I am hoping that maybe we are moving past this sort of logistics. I just tried to unpack the 9.0 image using tar which has worked in the past to let one modify loader.conf but I got a bunch of errors this time about files that couldn't be created so maybe this is not the recommended headless installation technique any longer. Any ideas?

I suppose iXsystems and the PC-BSD project might be a place to send out feelers as well, being more interested in end-user stuff than the pretty server-sysadmin heavy crowd here. There are a lot of people in this community interested in more than just servers, though, so I don't see why the fact FreeBSD is good for servers should be an impediment to seeking out people with an interest in tablet ports. > > *I*, for one, would hope that porting to the 'Rasberry Pi' has higher > priority.

I think the point of the initial email to start this thread was to see if there were people in the community with an interest in working on this project, and might actually be a fairly logical step toward an effort to "find a 'guru'" to work on it. -- Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

GSOC 2012 interest
Hi, Currently I am in my first year of Masters in Computer Science from SUNY, New York. I want to participate in GSOC 2012. I am new to the open source development arena, so what better place than GSOC to start with. So, I was going through the projects list offered by freebsd. In that list, I am interested in developing "Automated kernel crash reporting system". The reason for my interest is that I am studying OS in my current semester and I have done a lot of work on kernel level. Apart from this I have a good knowledge of C and have hands on html and sql. Also I have done a course on cryptography. So, this project seems appropriate for my start. So, I wanted to know is the project already in progress or its a new one. And any more information about the project will be very helpful. I am really interested in this project, so it would be very kind if you could share more details on the project and requirements so that I can work on them from now only and develop a good proposal.

Hi. I wonder why there are no more stable freebsd-stable snapshots made available on the ftp servers. Was there an official explanation? ftp://ftp.freebsd.org/pub/FreeBSD/snapshots The process of publishing them somehow stopped in mid-2011. From time to time it comes in very handy for testing purposes, to have snapshot releases available. Kai.
