Quick and Easy External Displays for Raspberry Pis etc.
by Steve Mynott 10 Jan '22

10 Jan '22

Occasionally one of the RPs crashes and since it's headless I can't see why it's rebooting. It's always awkward to put a full screen display on it. Can anyone recommend a small LCD screen (maybe 1024x768 or 800x600) with HDMI to use? Alternatively I've a number of retro systems which use RCA, Scart, VGA etc. and had a lot of success with early gen LCD screens (12"/14") cheap from car boot sales for around 10-20 quid. Although they usually have loads of ports, I've never seen any with HDMI. Do these exist? Or is any sort of cable/converter possible? I think I used to be able to use DVI as HDMI (?) But I've not seen DVI on these either. -- Steve Mynott <steve.mynott(a)gmail.com> rsa3072/629FBB91565E591955B5876A79CEFAA4450EBD50

Reducing size of pdf's
by Bev Nicolson 07 Jan '22

07 Jan '22

How do I reduce the size of a pdf without a) meaning I have to unzip to read it or b) shrinking it so the pages appear blank? I doubt I'll need to do this often but I'd welcome some pointers. Ghostscript is installed. I have just tried one option found by googling and got the second result. Not ideal. (Mint. 19.1 iirc.) Bev

List server upgraded
by Jonathan McDowell 30 Dec '21

30 Dec '21

I've upgraded the server running lists.alug.org.uk to Bullseye (Debian 11) and that has finally forced me to move from mailman2 to mailman3. Hopefully things are back up and functional again, but let me know if you see any list oddities. Getting the wiki back up on www.alug.org.uk is going to take me a little longer, but hopefully within a few days. Moin is still Python2 only and no longer part of Debian. J. -- ... Do you believe in happy endings?

simply a nuisance that confuses things. With my more technical hat on they are something which is difficult/impossible to implement correctly because there is no concise explanation anywhere of what they're supposed to do. ... and the same sort of problems apply to INBOX!

on the network; "get" or "put" the file[s] you want to transfer between Windows and Linux. This last is what I mostly do when someone sends me a Word or Excel attachment. In the latter case, I will typically export it (in Windows) as a ".csv" file which I can then tranfer back to Linux in order to run proper software on it! You can of course use the Windows telnet client as well (or the better one called "putty"). VMWare has given me a smooth interface to Windows when I need it, enabling me to continue to run Linux without re-booting. As someone remarked, it {will | would} be great {when | if} some good soul {gets | got} round to implementing something with similar power as OSS. But I can't begrudge the cost. It's been well worth while. (Of course, more recent versions of VMWare should be free of limitations such as I refer to above).

anymore unless you *need* colour printing. I have given up on my (Epson photo 900) inkjet and it now gets the cheapest compatible carts due to how it ate vast amounts of expensive ink and would clog the nozzles on a regular basis which would require dozens of nozzle cleaning attempts (and using more precious ink) to clear the think, this was also the same with my old Epson (fwiw Epson printers have the print head built into the printer, if it gets clogged you can't replace it) but my parents HP (which had been icky) at least has the print head built into the print carts. The reason I said to go with either the HP or Brother from the posted list of choices was because they should both work with Linux :) I also recently took the decision to get photos printed from an online lab as they can do much higher quality prints than I can with less hassle and probably around the same cost and that if I need to print something in colour I will just take it to the local print bureau who have decent printers and don't charge very much at all. Oh, and I have a Samsung ML-1510 laser for cheap copies which I can refill the toner carts for not much at all :) Adam -- jabberid = quinophex(a)jabber.earth.li AFFS || http://www.affs.org.uk/ || Not a filesystem

be doing double-pass printing on both sides of each sheet, i.e. so that the page allocations look like: [L] 40 1 [R] ---------------- --------------- sheet 1 [R] 39 2 [L] [L] 38 3 [R] ---------------- --------------- sheet 2 [R] 37 4 [L] ....... ....... [L] 22 19 [R] ---------------- --------------- sheet 10 [R] 21 20 [L] (where [L] and [R] refer to your description above). Or are you using a duplex printer which can turn the sheet over and print the next double-page on the other side immediately? If the latter there's no problem; if the former, and you have to go down [40,1] [38,3] ... [24,17] [22,19] and then turn these over and do [20,21] [18,23] ... [4,37] [2,39] then a slight modification of procedure may be needed. Now these can be folded/cut down the middle and bound into a book. You might either cut each sheer very exactly down the middle and use a glue binder, or place the sheets on top of each other as shown above and sew (or otherwise fix) them together down the middle and then fold them. In the latter case, a) You will need to guillotine the outside edges so that they are aligned flat, not bevelled (because of the thickness of the paper which pushes the inner sheets further out than the outer sheets). Then: b) It makes a much better job if, when you lay out the pages, you vary the page-offset (the gap from the left-hand margin) from sheet to sheet so that the distance from the righthand edge of the paper is always the same after guillotining off the bevel. What this means is that the central pages must be printed progressively nearer the centre-line of the sheet than the outer pages. This little detail is also readily arrangeable with groff (it's a rather professional detail, which you should find provision for in proper DTP/typesetting software, but would probably search for in vain in the likes of OpenOffice or Word. I don't know about Scribus). It may need some experimentation, though, in order to get it right (for which your trial copies, to be passed round the 5 or so friends for proof-reading etc., provide a perfect opportunity). Come back if you want any further hints.

scenes' stuff Access has something similar to Oracle's Row Id which is effectively a 'handle' for a row. This is what allows it to delete 'this' record. The front ends for mysql must have something similar so that when you are, for example, scrolling down a list of records there is something which tells you which record you're at. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice, that which can be explained by incompetence."

VERSION = 2 PATCHLEVEL = 6 SUBLEVEL = 4 EXTRAVERSION = -52 The last variable is often used to denote release candidates by the kernel team with (for example) -rc4 or -ac2. Likewise vendors such as RedHat or SuSE will append their own release number after extensive patching. Regards, Paul.

(several hours, occasionally 2-3 days) to reach some mailing lists. Inspection of the headers when the mails finally arrive shows pretty unambiguously that btinternet have sat on them for that time. I have no clue why this happens. When it does hapen, it tends to happen in clusters.

producing accented characters is to use the 'compose' key. This is a generic X method too. What you do is hit the 'compose' key followed by two keys to make the accented character, e.g. for e acute you do:- Compose E ' (or you can do Compose ' E, doesn't matter) However this does raise some other issues:- You need to have a 'compose' key, this is a matter of setting up your keyboard map to assign 'compose' to some fairly easy key combination. On my Linux box at home I have it set to 'Shift Alt Gr', on my Sun box at work there is actually a Compose key. Some applications may insist that you have the locale set correctly to show the accented characters, otherwise they just show a '?' for any character with a value above 127 because in the default ASCII character set they are undefined. On the system I'm using to send this I just have "export LC_ALL=en" in my .profile and this suffices to say that characters >127 are valid. However this is a bit of a blunt instrument and some systems may need more subtle setting of the locale variables to work well. It's a bit of a black art and it may take you a while to get everything you want working properly but it can generally be done. (Having said that I still cant type accented characters from where I am just at the moment because I can't work out how to set up a compose key on the X server I'm using). -- Chris Green (chris(a)areti.co.uk)
