  1. Here's how on The Thin-Client Challenge? · · Score: 5, Informative
    First, check out DemoLinux, and see if it has rdesktop on it or if you can get them to add it by sending a polite email. If so, then you are mostly done. Otherwise:

    To start, look at the files in this minimal distribution that runs X:

    2-Disk Xwindow Linux

    Look at other minimal distributions including the various floppy linuxes and bigger ones like Peanut Linux. Ibiblio's list of distributions is probably the place to start. Look at some of those distributions that come on busincard sized CDs.

    So pick one of these that seems configurable and set up a machine with the hardware you have in mind and install it (or boot from the floppies) and start adding to it. First do X, then your rdesktop client, whatever that is. Here's a hint: don't worry about removing compilers, unused libs, etc until you are done. Even then, keep several CDs of the "development edition" around, because you may need all that stuff to add more things in the future.

    To get your automatic boot up and start of the client and etc, look at how Mandrake does the automatic log in thing, and simply put all the commands you want to be run in your .xinitrc file, and then have the window manager be the last command. Look at man xinit for details.

    The final step would be to trim it down and set it up. My approach here would be to make it a bootable CD like Finnix. In fact, what I would do is start with Finnix, add X and the other stuff, and if I still had space on the CD, stop. Free space on a read-only medium is useless, you might as well put every single thing you think you might need on there until you fill it up.

    Some modifications I would make to Finnix would be putting all of the /etc directory in the ram disk, so you could re-configure things on the fly, and if your machine did have a local harddrive, maybe you could use that for swap. Running off a CD means that the user can just turn off the machine when done -- there is no disk to fsck, everytime it starts up it thinks it is the first time, so to speak. I've been playing with modifying finnix, I copied the cd to disk and modified some stuff, and got busy and never burned my new copy to see if it would boot.

    But in the long run, you have to realize that you are not going to get someone to do this for you for $150. You might try out DemoLinux and see if it already meets your needs as is -- I would expect that you would need to add that rdesktop thing. You have to either pony up the money, or do it yourself.

    Inspite of what some Zealot Hypesters may have told you about Linux being as easy to use as the interface to a coke machine or whatever, you have to come to the realization that Linux is about Freedom. It will always be easier not to be free. Worrying about "is linux ready to meet this bulletized list of requirements" is like worrying whether you might have to walk around a lot and get rained on sometimes and have to get a job if they let you out of prison. If you have any self-respect, it doesn't matter: a free system is the only choice. This means that you have to either put up with not being able to do what you want with computers, or bite the bullet and spend some of your own personal time reading and learning how to install things and configure stuff. Just like you spend your personal time reading the newspaper and going to vote.

    If I sound like a dirty gnu hippie Stallman-worshipping fanatic, it's because I am, and I'm proud of it.

  3. Contradiction from Eric, and Maxima on The Return of Eric Weisstein's World Of Mathematics · · Score: 1
    In Eric's commentary, I see a contradiction:

    I have come to realize how unusual it is to be working for a company that is run by people who still enjoy the core activities for which the company was founded. Very early in the lawsuit, a Wolfram Research response to the lawsuit mentioned that Wolfram Research has chosen to remain privately held in order to be free from the obligation to outside stockholders that appears so often to focus corporations inordinately on short-term financial results. Wolfram Research's principals believe that they can take the long and broad view of the corporation's mission, as they could not if they had to satisfy stock analysts and uninvolved stockholders.

    The behavior of CRC's representatives this last year has been, for me, convincing evidence of the wisdom of Wolfram Research's strategy. The people at my company believe in what they do, make money doing it, and have fun along the way. I didn't see much fun being had among the CRC people we dealt with.

    And then he blisefully continues in the very next paragraph:

    We eventually concluded that there was no real business discussion possible. CRC was simply incapable of listening to or evaluating an actual business proposal. So we weighed the costs of continued litigation against the costs of giving CRC some of the cash for which it appeared so hungry. The cash approach won.

    Hello ? If Wolfram is such a bunch of privately owned old-school in-it-for-the-fun boys, how come the cash approach won ? What happened to all the stuff about short term versus long term ? Didn't do much good to be free of all those "uninvolved stockholders", now did it ?

    Sure it does. It does a lot more, but it definitely does that. Look at the What is Kermit page and do a page search on "terminal emulation."

    A "terminal" is a keyboard and monitor (or in the old days, a teletype machine (that's where "tty" comes from), basically a keyboard and line printer) with a wire connection to a host computer. For each such piece of hardware built, there was a protocol for how the host computer could tell the screen what to display and what bytes would be sent with each keystroke. (Actually some terminals allowed you edit an entire line and then send it at once.)

    When I take one computer and hook it to another with a piece of wire, the software that causes the first computer to send exactly the same things to make it look like the terminal hardware is on the other end is naturally enough called a "terminal emulator."

    You can take an old PDP11, disconnect it's vt220 or vt100 terminal, hook up the wire to a computer instead, run kermit connected to that port, tell kermit to pretend to be a vt100 or vt220 or whatever, and the PDP11 should not be able to figure out that there isn't a real hardware terminal on the other end.

    These days you don't have to have a separate hardware port for each terminal, you can connect many at once via Linux's virtual terminals or networks or whatever.

  10. How to figure out key translation ? on Properly Configuring Terminal Emulation in Unix? · · Score: 1, Informative

    I have been trying to get full (i.e., all F-keys, escape and backspace/delete etc) terminal emulation going on a DOS machine connected to a linux machine over a serial cable. I can specify what terminal type that the getty should use on that line in /etc/inittab.

    On the DOS machine I am using kermit. There is a vt300.ini file which puts it into vt300 emulation mode. Except that if I connect to the linux machine, I have to do "set term type ansi-bbs" to be able to see any text, and if I start up midnight commander not all of the F-keys work.

    I looked the various "set key" commands in the vt300.ini file, and I had the hope that I could look at the termcap definition of vt300 (actually vt320) on the linux machine and somehow figure out how to set the F-keys to send the right thing.

    But no luck so far. How do you figure out exactly what mc is expecting for a certain key ? Isn't this somehow in the ncurses library related stuff ? Should I try a different terminal type -- perhaps midnight commander wouldn't work correctly even if I had a real hardware vt320 ?

    In general, how do you debug stuff like this ? Is there a program in the ncurses package, or that uses it, that I can run, press a key, and it will show me what the terminal emulator should send (in terms of what binary combination) to emulate that key ? Then I could generate the key-to-binary mapping by hand, and then use that to generate a file of "set key" commands to configure kermit correctly. If I was trying to emulate something with more F-keys than my keyboard, I could look into using shift-Fkey to emulate the higher ones, or whatever. But I would at least know what I needed to send, and that's the part I'm having trouble figuring out.

    By the way, the /etc/termcap file has some interesting reading in the comments. Check it out next time you are waiting for a compile to finish.

    There is no need to send anyone a microsoft .doc or .xls document, ever. MSOffice can read in html, rtf, and other formats. So the translation is only coming in, not going out.

    Well, perhaps the exception might be the excell spreadsheets. Some people mail back and forth a huge number of spreadsheets with fairly complecated macros, such that rendering the document as delimited text would loose quite a bit of information.

    The best thing to have is a single windows machine which you can access remotely for the purpose of occasionally loading up a received document and saving it out in another more interchangable format. The usual mode of operation would be to read the incoming document with OpenOffice, and only resort to that machine if the result is horribly broken; then you make changes or whatever, but save it out in an open format such as rtf or text, and only send open formats out of the company.

    OpenOffice can do the task. Keeping around a few of the windows machines as a backup and use as translators is probably something you need to do regardless of the quality of OpenOffice or whatever other package, as long as the people you communicate with stick with MS.

    But I mostly use Star Office to simply translate the document into html; I think process the document from there using emacs, first cleaning it up quite a bit.

    I also use Star Office to save .xls files as delimited test, and then process them with perl scripts.

    What you need to complete the ability to switch is a web-based way to convert MS documents. This way you can provide a few linux machines for people to use and see others use and get over the fear; documents can be submitted to a server through web page, returned as html or RTF or whatever depending on what you want to do with it. All those MS tools provide "save as . . ." functions in various formats.

    If you email an MS document to yourself at a Yahoo email address, you can go to the Yahoo web interface and veiw the document as html. For a small home office this is acceptable; for a bigger company, you search around in yahoo's site you can find a link to the company that provides the server that does that MStrash-to-html conversion.

    But what we really need (and have been needing for a while) is a set of CGI and visual basic scripts that will allow a person to install apache on a windows2k or XP or whatever flavor of the week with the cygwin stuff, and provide a small web page that will take submitted documents, load them into the appropriate MS tool and save them as the appropriate format, and return them to the user. You can already buy this for a price, but a GPLd project along these lines would break a lot of dependancies on MS. I hate MS too much to even acquire a copy of the OS and Office and learn VB to start such a project.

Also, using these tools does not restrict your freedom; you have the source code and the free use of it, and these same tools will be available to you should you work on other operating systems and architectures. For me, the advantage over cygwin was the nice package of stuff on the CD with the setup script, because most of the machines I was installing this on didn't have network connections.
