Recommend an IRC server

by vintagecoder＠aol.com

Can anyone recommend an open source IRC server, preferably BSD or MIT-style licensed, that doesn't have dependencies on scripting languages or much else? I'd like a pure C, C++ etc. solution if possible. I'm looking for something to test socket applications against. It doesn't have to be a super duper server or have zillions of features. Something basic would be good enough, but I will want to build and run it on several platforms. Thanks.

Vacuum 'leaking out'

The analogy that immediately came to my mind was that of holes in a semiconductor constituting a current of positive charges. I suppose one could also say that debt leaks into my bank account and is removed when my salary gets paid. All the while leaving a negative, reducing charge of debt in the account. /Jonas

I've been trying to contact Paul Anderson <useddec at gmail.com> for a couple weeks but haven't gotten a reply. Does anyone know what's up? Paul, if you're reading this, would you please contact me by private email? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Core memory cross compatibility

by colineby＠isallthat.com

Has anyone sat down and worked out interchangeability of memory parts on 16-bit core based systems. I'm thinking in terms of things like PDP-11s HP 21xx and DG Novas. I'm curious if anyone has compiled such a thing, aside from direct part number comparison -- or has guidance of non-like core stack replacement. I'm not planning on attempting to do anything of the kind just now, but it might be useful to know what's possible as supplies dwindle. --Colin

HP screen screen rot

That would seem likely since the glass was once melted in order to make the CRT. Whether continuous arcing damages the glass permanently or not is another question. I would guess that the heat in itself does nothing irreversible, but arcing does. I found this in a text about types of glass and manufacturing procedures for CRTs. It did not mention whether the damage was reversible or not. Your observation about connecting a glass rod across the mains and heating it certainly supports their warnings about reduced dielectric strength. On the other hand, I would suppose that severe localised heating could cause the glass to crack due to local expansion creating excessive stresses, so I would still be very careful with the soldering iron. /Jonas

KryoFlux - imaging of vintage floppy disks via USB

Sure, there is not much point sending SPS stuff if it's not in scope for the project because that project is only concerned with preservation of unmodified and undamaged commercial software. Our commercial venture KryoFlux does provide a service to help people generate IPFs. That is something else entirely and completely independent from SPS (other than the same people are involved, and it uses technology developed for SPS). That is a professional service as you would expect, any data generated is destroyed as per an agreed contract. Nothing stops anyone "archiving" other people's data. Most people don't do it because it is unethical - I am not sure why you might think it would be different for us? > My feelings exactly.

I'd be interested to understand why you think this. What are we doing wrong? Is it wrong to want to fund our preservation work by starting a commercial venture? What are we not making available? We've released the IPF library source, including an extremely accurate, cycle exact FDC emulator. We also have tons and tons of information on the SPS website about how things work (WIPs). IPF files contain the information about each disk formats, and now that is open, I am not really sure what else we can do? I am genuinely interested, because we do want to do the right thing (even if it might take us a while). Thanks, Kieron

That section of the FAQ is not actually completely relevant in this case. It refers to producing IPFs. If you want to write sector images, then there is of course no real need to create IPFs anyway in this case I guess. Our IPF creation software is a commercial product, and helps fund our preservation activity. Now that the IPF library has been open source, there isn't anything stopping somebody creating something similar of course, so that FAQ is out of date too. Kieron

That is not currently supported, no. We decided to do the hardest part first, writing IPF files, and doing it really well. As stated on our forums, other files, such as sector images, will come later. We are doing some C64-related work at the moment, but the plan is to support sector images for writing next. It almost goes without saying that, if it's sector images somebody needs for writing, then wait for that before getting a device. > I have an interest in archiving, but I'm also an avid tinkerer with old > hardware and often need to generate "real" diskettes from a sector image. Yes, absolutely. This is definitely a missing piece right now. I hope that helps clarify things. Kieron
