Re: gEDA-user: OT: Recommendations for laptop?
I am very much an open-source proponent. As I mentioned in my previous post, I run Gentoo Linux on my Apple MacBook Pro. Linux runs very fast and problem free on it, and the graphic programs like gEDA are especially awesome on its 1920 x 1200 screen resolution. Its true that when you buy a MacBook you are buying a hardware component and a software component, and in that sense supporting a closed OS, but I can overlook that fact if my ultimate goal is to run Linux on the best hardware platform I can find for it. Also it is extremely satisfying when a Mac user spies me working on his platform of choice and then discovers I am not using the stock software. (Cool! where did you get that application?) It gives me a great opening to evangelize my favorite OS. I think it is actually a strong way to support Linux. --ken On Sat, 2009-01-03 at 02:48 -0500, der Mouse wrote: - Closed source OS rubs some folks the wrong way - even when they provide free development tools documentation for coding on top of the OS, not having access to the guts is annoying. It actually can be anywhere from irrelevant to intolerable, depending on what you're trying to do. For me, crippling is usually about the right level. NetBSD does run on many of the Apple laptops, but then, as I put it before, most of the Apple benefits go away (if they haven't already - as I remarked, Apple's UI is not a benefit for me, for example). So given you don't like Apple, what do you recommend for a good laptop? It depends fairly heavily on what you want to do with it. Perhaps, for you, Apple _is_ a good choice - for example, if you don't mind spending money on the OS, and you just want to run (say) geda--pcb, it may well be a reasonable choice. For me, it isn't; the closed-source OS is pretty crippling on pragmatic grounds and intolerable on philosophical grounds. I haven't found anything I really like. The best two laptops I have so far are an IBM WorkPad z50 and a Tadpole SPARCbook whose model number I forget. Each has a non-Intel-architecture CPU (MIPS and SPARC), which I consider a benefit. Neither one has tremendous screen resolution (800x600 maybe? I forget), and their colour capabilities aren't flashy. Each one has difficulty with disks (the z50 has no interface designed for disk - I use a CF-interface microdrive - and the SPARCbook takes SCSI laptop drives, which are thin on the ground and usually small (~1G) when you can find them, and the OBP doesn't play nice with the IDE-to-SCSI laptop disk adapter I have handy, though another just the same works fine with my Voyager). The z50 has good battery life, something like six hours, mostly because I got a new battery for it; the SPARCbook has just about no battery life, but I haven't replaced its battery. Each has good keyboard feel and tolerable (but not especially good) keyboard layout - I'm picky about keyboard layout. The z50 has a fairly low RAM limit, and my add-on RAM for it died, so I haven't turned it on in quite a while - I don't recall what the SPARCbook has for RAM, but I think it's plenty. If I found myself needing a working laptop, I'd probably try to get each in working order, which means getting a new battery for the SPARCbook and looking harder for a RAM module for the z50. Oh, and look for multi-gig mass storage with a PCMCIA interface, for the SPARCbook. I know just about nothing about what's available new. I _really_ don't want to spend money on an Intel-architecture machine, and I don't know of anyone making laptops with anything else - though it hasn't mattered enough for me to put serious effort into looking. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML[1]mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B ___ geda-user mailing list [2]geda-u...@moria.seul.org [3]http://www.seul.org/cgi-bin/mailman/listinfo/geda-user References 1. mailto:mo...@rodents-montreal.org 2. mailto:geda-user@moria.seul.org 3. http://www.seul.org/cgi-bin/mailman/listinfo/geda-user ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: OT: Recommendations for laptop?
I use a wireless Logitech lazer 3-button mouse (actually two buttons and a center wheel). I don't think I would be able to do it with a one-button mouse either, or the touch pad for that matter. One issue with the mouse that I can't seem to get around is that the center button doesn't work in Linux context for some reason. The scrolling works, but clicking doesn't. Instead, the mouse functions as if three-button emulation is enabled--meaning that I get the effect of the center button click by clicking on the left and right buttons simultaneously--even though three-button emulation is not configured in my xorg.conf file. I think this is a side-effect of VMware Fusion. Its annoying but I have gotten used to it. I have heard that the Apple MightyMouse appears to be a single-button mouse but actually functions like a two or three button mouse in the sense that it can discriminate between clicks on the left and right sides of the button. I'm not sure if this could improve the user experience in gEDA or not. --ken On Fri, 2008-12-26 at 14:48 -0600, Mark Rages wrote: On Fri, Dec 26, 2008 at 2:16 PM, Ken Lauffenburger [1]k...@aavatech.com wrote : One more recommendation for MacBook Pro.

Re: gEDA-user: fabrication drawing -- how to modify, or create an alternate fab drawing
Thanks for the suggestions. A question: what does pcb use to fill in the Author: line on the fab drawing? I tried various combinations but so far no luck. --ken On Wed, 2008-04-16 at 13:51 -0400, Stuart Brorson wrote: Hi -- I have just completed design and layout of my first full-scale board and I am about ready for the fabrication step. My experience with the gEDA tools and PCB has been relatively painless so far, and the resulting schematic and gerbers look impressive and very professional. Glad to hear it! However the default fabrication drawing output from PCB is minimal and essentially just a drill drawing. I would like to add the other essential standard fabrication information, such as the stack-up figure, board material, plating specification, finish, registration spec, etc. Can this be done using PCB, and if so what is the best way to do it? Is there a layer that can be defined for this purpose, or maybe some keywords and text can be added to the .pcb file? In the past, I have exported .png or .pdf files from PCB, and then embedded the fab drawing as an object into a SolidWorks drawing. Then I have added all the other shrubbery required for a professional fab drawing. I have done the same thing with Visio, too. You could use any drawing package which imports .png or .pdf. PCB doesn't do nice looking fab drawings right now.

gEDA-user: gsch2pcb: unwanted merging of nets
What are the rules that gsch2pcb uses to rename nets? Is it possible to disable this, and if so what is the setting? Here is what is happening: ... Found duplicate net name, renaming [SRESET] to [SRESETN] Found duplicate net name, renaming [HRESET] to [HRESETN] ... SRESET and SRESETN, and HRESET and HRESETN are intended to be four separate nets. Apparently gsch2pcb assumes that SRESET and SRESETN are the same net and is trying to help me fix an error. I'm sure I can rename one of the nets to a completely different name and that would avoid the problem. But then the inherent documentation of my net naming would be less effective. Short of this approach, can I prevent the renaming of my nets?
