[DNG] Can not upgrade xserver
Приветствую. I can not upgrade xserver from version (i will call it farther "old"), that is in devuan version 1 to the version (i will call it farther "new") that is devuan version 2, having tried on two different machines -- desktop and laptop, nvidia and ati cards. -- Problem lays in permissions of course, for normal user. I tried package legacy and even now (on the "old" version), i use hand-written file Xwrapper.config, left from downgrade after several tries to make the new working. Can you tell me for which package version to look (let's call it a minimal set necessary "new" xserver to work for a normal user), that allows xserver upgrade from "old" to "new"?

Re: [DNG] PostScript vs PCL
Postscript's imaging model is still the archetype, I look in the Red Book or its descendents whenever I have to code 2-D imaging. They even explain the matrix well. If you want something that *isn't* an interpretive language, real PostScript interpreters also will print directly from PDF. The downside of PostScript is that the input can be arbitrarily complicated, although when this is the case it's usually deliberate. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

It's a very long time since I last looked at PCL, but I recall it was rather horrible to work with. As I mentioned earlier, you can do tricks in Postscript like redefining the showpage operator (typically by just adding the right code to the beginning of the file/stream) to automatically do something to every page. But in PCL you can't - you'd have to go through the file finding every page feed, and adding PCL code before each instance. PC is also (IIRC) resolution dependent, so you don't get the "write once, print on any printer" capability of PS. And it's full of non-printing characters (escape sequences, form feed, and so on) while PS is (IIRC) supposed to be "7bit channel safe" and contain only printable characters (though I think it can handle 'binary' files for machine generated code). It's hardly surprising that PCL is faster on any given hardware - it does a lot less as the code generator effectively has to do a lot of work that's done in the printer (or to be pedantic, the RIP*) with PS. As I say, it's a long time since I last looked at PCL, but IIRC you have to do graphics using resolution dependent co-ordinates - while with PS, you can use the default units of points (1/72nd of an inch) or it's trivial to rescale things and use any scale you want in your code. In fact, you can tell PS to apply an arbitrary transformation matrix to everything. All this ability means (potentially) a lot more processing - so it's bound to take longer on the same hardware. > The ideal printer is a networked model that does both. Indeed, especially to deal with the software written by vendors with a "nothing exists other than PCL" attitude - gr. * Raster Image Processor - converts the input job into a raster to send to the print engine. They are mostly built into the printer, but in many high end systems can be a separate unit. One I've worked with was basically a PC running Electronics For Imaging's proprietary RIP software and with an interface card for Canon's colour copiers - back in the days when such things were fairly new and very high end, and it was possible to spend more on the printer setup than it cost to buy some houses ! ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Being the original poster, I can confirm that CUPS+printer-driver-hpcups worked for the printer in hand via JetDirect, without d-bus. I was tempted but did not have time to test the LPRng solution. It is a cheap (€50) HP printer/scanner accessible via usb and wifi. Nevertheless, it provides a web management interface, network scanning through that, Bonjour, cloud printing, IPP and JetDirect network protocols... Thank you, that was the kind of answer I was looking for originally.

file string readline substring bool
which reads a line (terminated by a newline) from file and stores the
characters into string. bool is false if EOF was encountered before the
newline.
and:
file string readhexstring substring bool
-
which reads hexadecimal (A-F) characters, interpreting character pairs
as 8 bit integers (0-255).
and:
file string readstring substring bool
--
which reads characters from file into string until it has been filled or
EOF is encountered.
They're all described in Adobe's "Postscript Language Reference, third
edition" My copy's 19 years old now, so there may be something more
recent.
Though I've drawn up the 8 drawings of my house plans in a bit over 800
lines of manual postscript: plan, elevations, sections, and site plan,
I've not had to resort to the above commands. (Well, sorta manual
postscript - building a bunch of functions to draw windows, doors, smoke
detectors, and wall sections with a rotation spec, etc., made the work
ever less manual. (The local government planning department is happy
with the drawings, but I still need a building surveyor to sign off on
the design. I'll need the money saved on architects for the extra stuff
the fire authority wants.)
When a row of 14 solar panels can be drawn on the roof with one line:
14 { 1650 500 box 70 0 rmoveto } repeat stroke% PV panels (one row)
it's not bad at all. (The narrow width is due to roof angle.)

There was online a video describing the whole Devuan package pipeline, but I understand we should probably provide a better layman description of what amprolla does and of what it does not. The latter point seems to have created a lot of confusion in the past. I might give a try at writing something short at some point.

If it is processed on host to convert it to something a non-PS printer groks, it ought to work (modulo being able to read partial files). But then again, you were all talking about PS printers, IIRC.

I'm one of those many and not just because I still have an odd Debian machine running. I also keep getting them because I know that Devuan will get most of its security upgrades straight from Debian anyway. However, using a simple web search (using Duck Duck Go, if that matters) I cannot seem to easily find anything on a Devuan website that clearly spells this out. Perhaps that is something that can be improved? The landing page lists deb http://auto.mirror.devuan.org/merged jessie-security main in the Packages section but there's no mention of how Devuan handles security issues. A link to https://devuan.org/os/security/ on the landing page as well as a blurb on that security page explaining how things work would go a long way? Personally, I have no problem with *not* getting duplicates of Debian's DSAs. Then again, I also have no real problem with getting them ;-) # Already get "duplicates" from Ubuntu as well :-/ What I'd definitely do like to see is Devuan Security Announcements for the *forked* packages.
