It was, of course, intended for Rickman, who seemed doubtful about writing Linux programs and/or C. Hopefully it will also be useful for anybody else in his position. I would have found Kernighan&Pike very useful when I was in starting to write significant programs (or even simpler ones that weren't throwaways! ) but at that point even K&R hadn't been written, let alone UNIX. As it happens I'd already evolved a fairly similar style to that described in K&P, but even so I found it a useful read simply because it is extremely readable and offers a good description of how to write well-structured programs. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |

I'm not sure why you think I am "doubtful" about writing in C. I am.. er, was... fairly experienced in C, but I have not used it in a decade or more and don't intend to use it if I don't have to... and I *don't* have to. Don't get me wrong. There is not much bad about C. I just like the interactivity of Forth. I find it much easier to get stuff working in Forth than to use a debugger in C. > I would have found Kernighan&Pike very useful when I was in starting to > write significant programs (or even simpler ones that weren't throwaways! > ) but at that point even K&R hadn't been written, let alone UNIX.

My copy of K&R is sitting in my bookcase along with a couple of other C books and a small collection of VHDL books. My two Forth books are laying on my desk next to my work area... -- Rick

Yes, that thought occurred to me last night, but I already have code in Forth for my app. I will try Python another time. Btw, is that why it is the Raspberry 'Pi' as in 'Py'thon? -- Rick

Well it's a comparable board in the same space, but more technically oriented, has some different capabilities, worth looking into if you're into these things. You might like its realtime coprocessors, for example.

Since it has most of the capabilities of a PC I figure it would be nicer to use in the lab than a PC, mostly because it is so much smaller. I also have been considering rolling an add on board for the rPi but so far have not figured out what it would be. So this is a learning experience. The BBB is interesting, but support is through a Google group and the market is *soooo* much smaller. The rPi really rolled over top of it and all the other SBC Linux units out there. They've sold 3.8 million so far. For 99% of the things I would do with a Linux SBC there is no difference so I will use the one with better support. -- Rick

From what I've read, YES... The intent was a small Linux teaching
computer with Python as the primary programming language. True, being
Linux, pretty much anything is available.
The BeagleBone Black is similar, but the primary programming language
was Javascript using a Javascript interpreter accessed via a web browser.

Since you're talking about a Linux computer, this seems like a good chance to try one of the 1000's of other languages avalable for it. The Pi Foundation like Python and yes, the "Pi" in the name does refer to Python, but it's just another Linux system at the end of the day. Python is just one more language you can use with Linux. There are at least three different Forths avalable for it. And Cobol, Ada, brainfuck and who knows what else.. (even BASIC) I'd suggest not picking a language because it's popular, but picking one you know how to use - and it seems Forth in this case is just what the OP wants. Gordon

(even BASIC) What are the other two Forths? Not that I would likely use one, but I'm curious. gForth runs on the PC as well and I am expecting to have one program that I can run on both platforms. > I'd suggest not picking a language because it's popular, but picking > one you know how to use - and it seems Forth in this case is just what > the OP wants. Yeah. I like your approach. :) -- Rick

To see what is available in the standard software repositories: "apt-cache search forth | grep -i forth" (include grep to weed out things which are merely related).

Clearly I need to learn more about using Linux. That is no small part of the reason why I am using the rPi. But it seems every time I try something new I feel like I hit a brick wall. I just installed Xemacs on the pi and when I run it I feel like I need to go back to basics. It is so different from any other editor I've ever seen that I am totally stumped on getting started with it. Fortunately it has a lot of materials. :) I will try your command, thanks. Another learning experience. -- Rick

This command only turned up gForth and yForth. I'm happy with gForth so far. I brought my laptop to the workbench where the Pi is and it is pretty clear that I need to do the remote login thing. Trying to use two keyboards and two mice will likely drive me insane... or more insane. It will also get around the lack of a pipe character with my Dell keyboard. -- Rick

I can't say I follow your reasoning. I don't see how bit rate has anything to do with the issue. If a read is requested and there is no data in the read buffer, the routine returns indicating it read no data. If there is data in the buffer it returns the data and the lesser count of data in the buffer and the amount requested. Actually, this is the same as the no data case where it returns the data in the buffer which is none and returns the size which is zero. In all cases it returns immediately. If the program wishes to wait for data it just sits in a loop checking for new data and hopefully wasting time by calling a wait routine rather than tying up CPU with a spin loop. Where exactly is the problem? -- Rick

A networked server with access to multiple serial consoles. Either to provide network access to machine consoles or to give client terminals a logon screen and some basic commands to connect to other computers over the network. http://en.wikipedia.org/wiki/Terminal_server

I said LAN because I wouldn't connect anything like this without making sure there is a firewall between it and the Internet: AFAICT, while most of these devices support telnet connections, none support SSH or any other encrypted protocol. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |

Juniper networks calls it Circuit to Packet (CTP) and has a line of products that do that. In fact, I build a daughter card that replaces their serial port interface with a dual audio and digital interface with the smarts to do special interfaces like IRIG-B and time stamped digital data. They have never called it a "terminal server" though. I had the impression that Albert was talking about software to run *on* the MSP430, but maybe not. -- Rick
