Re: [9fans] Inserting Special Characters into Acme
I'd have another window holding the special characters, and just copy-paste them in the lines you want to (mouse chords are the key for doing this quickly). Obviously this makes sense only if you have to insert few special characters per file, and not to many files. But if you want to add them at the end of each line I think that ,s/$/SP/g should work. Replace SP for any string of characters you need. 2009/8/17, Aaron W. Hsu arcf...@sacrideo.us: Is there some way to insert special characters into Acme text windows?

Re: [9fans] copying a venti
Also, I have since discoverd the venti/copy command which looks to be exactly what I should be using, but how do I generate a score to copy the whole venti tree? There's no such thing as the whole venti tree. A venti store may have lots of trees representing different fossil partitions, vac(1) archives, etc. You would have to find every root block (or every one you care about preserving) and venti/copy it. If your venti store holds nothing but the archives from one fossil partition, then in theory a venti/copy of the most recent archive score will transfer the entire dump history. But from my experience of corrupted fossil archives I would want to do some very careful checking to make sure nothing was lost.

yes, having this score makes your files available to anyone with access to your venti. i'd suggest keeping it off the public network, assuming you have things on there you care about.

I have not been able to convince coworkers that filesystem namespaces are the way to go. I think they think it is too hard. *shrug* you can lead a horse... Funny, the problem I usually have is that people think file systems are *too simple*, oh, no data types other than *byte stream* and *drectory*, and no type checking! We are all going to die! Interestingly enough, people dealing with management of servers have been using stuff like SMASH CLP, which uses commands like cd and show, which may as well have been cd or ls to access system resources. I'm talking about smart power strips from Raritan, which have power monitoring and control per receptacle. So really, a lot of the things I do like about plan 9 are just nearly there in the wild in some cases, and feel quite natural. The next step is to make a generic CLP filesystem that speaks 9p :-). Might be fun, but I don't have an extra 600 dollars for a power strip right now :-) People seem to have trouble believing something simple can do a job that they have convinced themselves needs to be very complicated. Seems like in some cases people still do want the simplicity of filesystem access. So perhaps we're not entirely screwed yet. :-) Dave uriel
Re: [9fans] securing venti and fileservers was: (vac errors after updating to latest p9p archive)
Less of a here's my experience than a summary of earlier conversations with various people, but still perhaps relevant or helpful: 0) Venti contains neither authentication nor authorization. If you care, you are advised to stick it on a trusted network, or listen only on loopback. 1) The venti protocol reserves space for auth (see VtTauth0 and VtTauth1 in /sys/include/venti.h), but I'm pretty sure nobody implements it. Certainly I haven't found any definition of those fields. 2) My biggest security concern wrt venti is denial-of-service by way of spamming my disk (intentionally or not). /sys/src/cmd/venti/ro.c implements a read-only proxy which reduces this risk. 3) The proxy also provides a useful example of how more complex proxies could be constructed. What I'd like (it's on my todo, but down a few rungs) is an extended version that allows r/w access from trusted hosts/networks and r/o from everyone else. 4) There's always ssl or the like. Some people argue that's the best path to take; I'm less convinced. - P.S.: I have no idea why, but gmail thinks an appropriate ad for this topic is for Emo Teens: Explore Emo Style Personality.

Some people argue that's the best path to take; I'm less convinced. i think it makes a lot of sense to use ssl like a streams module. push it when necessary.

[9fans] Awakening the Dormant and Printing with the Illiterate
I've been looking into the tools of Research UNIX versions 7 and 8 and 4.2BSD, as well as other old utilities that we may still find useful. So, with the sources at hand of most such programs, I've started porting some to native Plan 9. As the ports are completed, I'll make them available in /n/sources/contrib/akumar/^(cmd relic). Only a couple exist so far; diff(1) files are included for comparison - I've tried to retain the original coding style and logic. See the respective NOTES files for extraneous comments in the style of annotations, and some background information on the tools. If there are any such tools you would find useful and would like to see ported to Plan 9, let me know (perhaps offline). Thanks to Russ Cox's help and Prof. Kenji Okamoto's code, I was able to get my Post- script illiterate printer, an HP OfficeJet 5610, to print with Plan 9. For anyone else requiring IJS support in gs(1) (hpijs binary included), the necessary files are in /n/sources/contrib/akumar/gs -- see the NOTES file therein for documentation and references.
