@Plergux Drueni! ('Gwisgo' yn lle 'gwysgo'?) Truth to tell, I'd say I'm a long way from 'mastering' English, let alone anything else. I think they just use the term really to indicate courses aimed at fluent speakers as well as learners. Or maybe they just ran out of ideas after 'uwch' ;).

Alan Munn

@cfr Hi good to see you back. How are things?

cfr

02:38

@AlanMunn Thanks. It's been a difficult year!

Alan Munn

@cfr Sorry to hear that. (I'm assuming you mean apart from the pandemic and Brexit).

cfr

@AlanMunn Yes, though there's that, too, of course. My dad was very ill in the autumn semester - in and out of hospital. Unfortunately, being in hospital triggers paranoid hallucinations, so ... er ... you can see how it would be tricky, I expect. Then ... er ..., yeah. He's on the Welsh 'shielding' list, so pandemic on steroids. 'N we haven't even got to Brexit yet ;). How are you?

Alan Munn

@cfr I'm ok. Just finished a full semester of Zoom teaching. And my mum is in Toronto, so I haven't been able to visit for getting close to a year.

cfr

@AlanMunn That's tough in a different way. My father is part of the same household, so escape rather than visiting is what I'm missing :(. I don't even get to go to work. Like you, I've just finished a semester on Zoom (though I'm presumably doing much less than you). Does Zoom audio disappear for you? Wondering if it's a Linux thing.

Alan Munn

03:02

@cfr No Zoom has been very stable for me. No problems whatsoever really. I've been using my phone though for audio/video, and my computer for sharing.

@cfr So I have my phone on a little tripod and login once with it and once with my computer without any audio. So not really a good comparison.

cfr

03:29

@AlanMunn It's mostly I can't hear the students, especially if I enter or leave a breakout room. It's rather weird. We're all now fairly adept at it. So nobody thinks it weird if, having just closed the breakout rooms, I invite everyone to join a new one to continue as a whole class. Bit dotty, mind.

Alan Munn

@cfr Strange. I haven't made much use of breakout rooms myself, though.

cfr

@AlanMunn Ah. I occasionally have problems when starting the session (maybe once), but it is really the breakout rooms which seem to trigger it. Unfortunately, I use those a lot. (Apart from the audio thing, I think they're fantastic. Definitely worth using if you usually put students in groups.)

Alan Munn

@cfr I should probably do it more than I do.

cfr

@AlanMunn Definitely easier in person. Much harder to judge when to bring them back with the Zoom version. But it works surprisingly well, all things considered. Far better than I expected. Who knew a university could licence a really useful, working, pretty slick bit of software?

Alan Munn

@cfr Yes, that is definitely harder. And in fact that's perhaps the biggest problem with Zoom teaching: it's impossible to gauge the responses of the students. But Zoom has been a good thing. That and my iPad (which the university did not supply).

@cfr One thing that's quite wonderful is the ability to move things around after you draw them, along with never forgetting your coloured chalk. :)

cfr

03:38

@AlanMunn Oh, no. The university didn't supply anything.

Alan Munn

@cfr Well we do get a new laptop every three years if we want. Although with Macs I can't be bothered so I usually get one every 5 or so.

cfr

@AlanMunn You draw with it? I've never tried that. When screen-sharing?

Alan Munn

@cfr Yes, I teach almost exclusively with a blackboard in real life, so I just use a note taking app on the iPad and screen share and teach that way. It works really well.

cfr

@AlanMunn If my (own) laptop breaks, my classes stop. I don't have a second device. I don't have university equipment.

Alan Munn

@cfr The tree I posted in the chat last week which you commented that I should have used forest :) was from one of my classes.

@cfr Luckily we have a bunch of Macs lying around of varying vintages, but so far no disasters.

cfr

03:41

@AlanMunn I guess a touchscreen would be crucial. I've been using slides, though I've moved away from slides usually in newer modules. But I can't do interactive slides now because I can't find a PDF viewer on Linux which lets me fill in forms in presentation mode.

Alan Munn

@cfr I've never tried that. Sounds fancy. But the Apple pencil +iPad combination is really quite astoundingly good.

cfr

@AlanMunn Lenovo did send an engineer, so my screen isn't blobby-yellow now. But my warranty has expired now, too, so just have to cross my toes.

Alan Munn

@cfr The fun part will be if we get a big ice storm and lose power. A few years ago we lost power for 10 days over Christmas.

cfr

@AlanMunn You're making me envious. But that stuff isn't cheap! I usually have form fields in my slides which I fill in during class.

Alan Munn

@cfr No, it's not cheap, but from my perspective worth it. I do all my marking on the iPad as well.

@cfr I've done that for years, long before the pandemic.

cfr

03:45

@AlanMunn Eek. More likely here would be VirginMedia broadband dying. A power cut is possible, but they're not as common as in the US (or CA?). We bury power lines.

Alan Munn

@cfr Yeah, as you know, very little buried lines here. And our neighbourhood has beautiful but old silver maples, which are quite susceptible to breaking.

cfr

@AlanMunn Everything strung up in the air ... perfect for places with hurricanes, tornadoes, ice storms, snow storms .... Of course, it is cheaper.

Alan Munn

@cfr Yes exactly. But that's the US in a nutshell.

cfr

@AlanMunn ;) It always looked so makeshift to me. You see it and you think, 'they'll be coming back to do that properly in a day or two'. I'm surprised they don't have gas and water up there, too.

Alan Munn

@cfr :) To be fair though, the population density is so much lower in most of the country, which is partly why burying isn't particularly economical.

@cfr And once you get out of urban and suburban areas, gas is above ground, since people have big tanks of it outside their houses.

cfr

03:53

@AlanMunn True, but you don't have to do it everywhere. Most of the main power lines are overhead cross-country here. But you still see them strung up in pictures of NY.

Alan Munn

@cfr Yes that's true, in some parts.

cfr

@AlanMunn I suppose that's true. And water towers. Maybe they're just meant to be decorative?

Alan Munn

@cfr There must be water towers everywhere though? It's true that they're especially conspicuous in the US small towns, as a way to advertise the town or the local high school football team

cfr

@AlanMunn Burying them does mean somebody is always digging up the pavement, though. They're supposed to coordinate them, but that doesn't always work. So you have power at home, but you fall into a great pit on the way.

@AlanMunn I don't think we have them. Never heard of one here.

Alan Munn

@cfr True that. Of course here in Michigan the roads are so bad it doesn't matter if they're digging them up. The joke is "In the UK they drive on the left. In Michigan we drive on what's left." :)

@cfr Something must be providing the water pressure though. I guess big pumping stations would work too.

cfr

03:58

@AlanMunn According to Wikipedia, we do have them. They claim there's one in Cardiff.

Alan Munn

@cfr Yes, that would be my bet. They're just hidden. Gravity is a much cheaper way to generate the pressure.

cfr

@AlanMunn However, we aren't using it?

The Water Tower at Cardiff Central Station, Cardiff, Wales is a Grade II listed building, previously used to supply water to steam locomotives on the Great Western Railway. It is located next to the western end of Platform 0, overlooking the River Taff. (en.wikipedia.org/wiki/Water_Tower,_Cardiff_Central_Station)

Alan Munn

@cfr Oh so nothing to do with residential water supply then.

cfr

@AlanMunn Doesn't seem like it, no.

@AlanMunn According to Wikipedia, the alternative is pumping, but this isn't much used as it risks contamination (but this is marked as dubious). According to the BBC, water pressure is created by gravity because reservoirs are generally higher up. Doesn't say what they do when they're not.

Alan Munn

@cfr Yes that's the other alternative. In fact I remember now that there's an underground reservoir halfway up Mount Royal in Montréal right next to McGill. We used to play softball on top of it. So I guess if you have enough hills it can work. Too bad for Kansas. :)

cfr

04:06

@AlanMunn I've actually asked this question before, but I don't think I've ever got a fully satisfactory answer.

@AlanMunn Great for Wales, though. Two things we have plenty of (apart from covid): rain and hills.

Alan Munn

@cfr Yes indeed. When I was a child we spent an entire 10 day holiday in a caravan in Wales, and it rained for the entire time. :)

cfr

@AlanMunn Sounds about right. It doesn't always do that, but certainly can. Where in Wales?

Alan Munn

@cfr No idea really. I was very young at the time, probably 4 or 5.

cfr

@AlanMunn We're a bit sensitive about reservoirs, actually. They flooded a Welsh village to provide water for Liverpool ....

@AlanMunn Hope your parents had a wet-days list. My mother always had lists of places we could go if it rained. If we wanted to go to one and it didn't rain, it'd get put off until later in the week because it would almost certainly rain at some point.

Alan Munn

@cfr Wow. Yes, water is quickly becoming a serious issue world wide. Here in Michigan we have a lot (being surrounded by it) but we're furious that Nestlé gets to pump 1/2 a million gallons of ground water a day, for $250/year!

@cfr Yes, apparently there were lots of games and lego, and my sister and I were at an age where we still thought we could play with each other (she's 4 years older than me.)

cfr

04:14

@AlanMunn landoflegends.wales/location/llyn-celyn

Alan Munn

@cfr Wow. I had no idea about this. That's horrible.

cfr

@AlanMunn Oh, we had going places. Never stayed in the caravan. Farms with petting animals, butterfly houses, museums, mills & things.

@AlanMunn Thank-you. Yes, it is.

@AlanMunn & Boris Johnson is trying to unpick devolution undercover of Brexit. The Internal Markets Bill isn't just about breaking international law. Every one of the other devolved nations is against it because it grabs back powers which were devolved to Westminster.

Alan Munn

@cfr Yes exactly.

cfr

@AlanMunn Covid has brought devolution to Johnson's attention rather dramatically. He could stand up and announce all the rules he liked, but they didn't touch anything beyond England. Health is devolved.

Alan Munn

@cfr I'm a bit more in tune with Scotland than Wales on these issues.

@cfr Time for bed. :) Nice chatting with you again!

cfr

04:27

@AlanMunn Wales is much more in tune with Scotland than either is with England. Wales is doing much worse than Scotland with the virus, but it isn't for want of trying, as far as I can tell. We were coming out of 'firebreak' as England went into a 'circuit breaker'. Wales has less power than Scotland and there's less support for independence, but support has increased here during the pandemic, as it has in Scotland.

@AlanMunn Nos da;) Very lovely to 'see' you again.

Alan Munn

@cfr That's not surprising.

Nasser

09:39

I thought I ask here on this, since many of the experts here know about pdf. I have lots of PDF files, each is one page only. But this page is very large. some are 15 x 60 inch and different sizes like this. So when I include in my latex file, I scale to fit on 8.5 x 11 inch and becomes very small and hard to read.
Any one knows of a tool (may be Linux command line tool) or any other way, to split this one pdf page to 8.5 in by how many pages are needed so each is 11 inch long?

I searched and so far not able to find anything. I have PDF adobe 9 PRO on windows, and I see no option there …

Faheem Mitha

@yo' That's an alarming number of indentations. I thought there was something wrong with my screen.

Could we declare a moratorium on the nested quoting?

Anyone remembers when they needed to clear something from the terminal and didn't know the right terminal commands? So just posted rubbish to make the things scroll away?

Rmano

@PauloCereda time to build an AppImage... will look at it when I have a bit of time

Did the same for QUCS rmano.github.io/qucsAppImagesBuild

David Carlisle

@Nasser you can just do that with the graphicx package

Rmano

09:50

@PauloCereda Aaaargh --- two screens to scroll and I can't see the message

@yo' reset

Nasser

@DavidCarlisle oh, I did not know that. Ok thanks, will go look into it. I did not know the graphics package can split one single PDF page to smaller sizes.

David Carlisle

@Rmano or clear

Rmano

@DavidCarlisle yes

Nasser

@DavidCarlisle I assume you meant graphicx. I'll go read the docs....

yo'

@Rmano you have to click on a timestamp as deeply nested in the quote indents as you can see; that will bring you to one of the earlier messages that has less indents :)

David Carlisle

09:52

@Nasser use viewport= 0 0 5in 10in or whatever rectangle yoy want for the first page, then input it again with viewport= 5in 10in 10in 20in to see the adjacent rectange...

@Nasser graphics or graphicx actually

Rmano

@yo' Ah, wow! Thanks

Nasser

@DavidCarlisle But I do not know before hand how many pages I need from that one long page? These are random PDF files, each has different one long PDF page in them. I wanted a tool to automatically chop this one page into as many as needed... but will look at this viewport option.

David Carlisle

@Nasser you can get the size of the image and you know how big your page is so you can work out how many tiles you need.

Nasser

@DavidCarlisle Yes. In theory I can. So I need to do some calculations basically. Doing arithmetics and algebra in Latex scares me. I can only figure how to add one number to another in Latex :) That is why I was asking if there is a tool that does this automatically.

Apparently there is an option in PDF acrobat DC which does this

"Open the PDF in Acrobat DC.
Choose “Organize Pages” > “Split.”"

But I do not have this option. I have adobe acrobat 9 PRO. It looks like acrobat DC is some new adobe PDF product.

David Carlisle

10:17

@Nasser this is pretty trivial arithmetic just keep adding \textheight until it's bigger then the height of your image, but also aren't you using luatex, you can do the arithmetic in Lua if you prefer

@Nasser or since you like CAS systems do it there and just write out the \includegraphics calls needed. You know in advance your image size and how big your page is so you could use maple or anything you want

Nasser

@DavidCarlisle These are files I got from the university. One teacher likes to put all their lecture notes in one long page for some reason. Since they use some writing tool to write everything om, then send the final notes to us. it comes as one page PDF file. So the final PDF is just one loooong single PDF file.
If I can't find a tool that does this from command line, on Linux, I'll see if I can do it in Latex. I am not very good in Latex programming and such.

David Carlisle

@Nasser actually if it is text not an image then you probably want different techniques. For tiling an image you can use exact dimensions and split every 10in or whatever as it will tile together, but for text you really want to spit between paragraphs or at least between lines, doing it mechanically as suggested above will end up with top of letters on page 1 and the bottom of the same line of text at top of page 2. You should do it manually and chose the tiles appropriately.

Nasser

@DavidCarlisle it is an image. Please see screen shot

The above is just one file at random. 60 inch long single page. I am not worried about the width. I can scale that. It is the length which is the problem.

David Carlisle

10:33

@Nasser sure but it is an image of text so there is no point in tiling that, mechanically cutting it every 10in, as the cuts will chop through lines of text and diagrams etc. Just spend 5 minutes in each case chopping it at sensible places between items.

Nasser

@DavidCarlisle I know I can do it manually using CROP tool in pdf reader. But I have so many such files. will take me for ever.

David Carlisle

@Nasser what's the point in making unreadable files quickly?

Nasser

Not important if it splits and cuts some words off here and there. It will still be readable. These are just class notes. But I will see if I can find a tool to do it in batch mode on Linux. if not, will try the Latex route.

Rmano

@Nasser pdfarranger can split pages vertically, and there is a trick (rotate+split+rotate again) to make it horizontally --- there is a feature request to allow a more generic way: github.com/pdfarranger/pdfarranger/issues/306

Nasser

@Rmano thanks! Will go now look into it.

Rmano

10:40

This is just a page split in two. It is rigid though: just split in the middle. I would really use gimp for this... select, cut, copy on a new layer, and then generate the PDF. So you can control overlaps, logical pages etc...

David Carlisle

10:53

@Nasser why is the long page a problem?

Nasser

@DavidCarlisle because I want to include those PDF files into my main Latex document, in separate chapter. And since each is one page, theose pages show up as very small when I scale them to fit in a single 8.5 by 11 inch in my main document and hard to read.

David Carlisle

@Nasser that's what I mean. Do you print on paper? why not let that page be long?

Nasser

because it will hard to read on screen when scaled?

One has to zoom in.

David Carlisle

@Nasser why scale it you have a scrollbar.

Nasser

@DavidCarlisle sorry, not following you. these pages will be too small to see when scaled to 8.5 by 11 inch, compared to the rest of the document. If I split the long page into many pages, then this problem will go away.

Ulrike Fischer

11:04

@Nasser what David means, why don't you include them in your main document as they are? As unscaled and long pages between your standard pages?

Nasser

@UlrikeFischer then it will hard to see without having to zoom. In addition, I want to also print the final document. So will hard to read, as everything will be scaled down to fit into 11 inch long page. Just like I showed in the screen shot above. it is like scaling a large image into tiny one. Hard to see the details any more.

Ulrike Fischer

@Nasser why should it be scaled when you print? Can't you tell your printer driver to tile long pages? With adobe reader I can print large posters on a number of pages automatically.

Nasser

@UlrikeFischer the final PDF document will say have 1000 pages. few of these pages come from these one-long-page PDF files. When I want to print this document, I click print. It sends the whole file to the printer. These long pages already been inside and scaled to fit each into one 11 inch page.

I do not print things separately. I combine everything into one document, in Latex. Then print the final document.

Ulrike Fischer

@Nasser well my printer driver has the option "tile only large pages".

Rmano

11:21

@Nasser I still think that in this case using GIMP is the better option. You will have to manually cut the pages, yes, but that's the only way to have it starts and stop at points that are really readable in a separated way.

Nasser

@UlrikeFischer Yes, I have that option also. I normally set it to "page scaling : shrink to printable area". I never tried "Tile large pages". Then you are saying when I include that looong one PDF file into my main latex document, I should not scale it? And keep it as is? But then what about screen viewing? One would still have to zoom in to see the details on that one particular page. I want all the pages on the main document not have to use zoom to see them.

@Rmano I know how to crop that one long page into the sizes I want, using CROP tool in my pdf acrobat 9 pro. It is just too much manual work to do all the files one by one. I tried pdfarranger, but so far, can't figure how to use it to do what I want. not easy to use. may be I should just do it in Latex and use lua to do the calculations.

Paulo Cereda

@Rmano ooh

David Carlisle

11:47

@Nasser no you would not have to zoom, you can see it at normal zoom, and use the scrollbar.

Nasser

@DavidCarlisle Please get give sometime to make an experiment. I will try to make a latex file which include that one looong pdf page file, and not do any scaling when I include that PDF from outside. Then compile it and see what I get.

Rmano

@Nasser yes --- could be a solution. If I had that problem myself I would write a python script to generate the includegraphics with, say, a 10% overlap and be done...

Ulrike Fischer

@Nasser see tex.stackexchange.com/a/509903/2388

Nasser

@Rmano This is not an easy problem as it sounds. I google "how to split pdf page" and I see many many people asking for help on this problem.

@UlrikeFischer thanks. I know pdfpages, and used it alot before. Main problem is that it does clearpage each when it reads a pdf file. But besides this. I just tried it. Yes, It now includes the long_page.pdf file ok. And no zoom is needed. One problem is the width. Here is screen shot. if I can figure how to use pdfpages and scale the width, this solution could work. WIll look into it.

Since the long_page.pdf has wide page much more than 8.5 inch (as well as loong). Will see if I can scale the width to fit current pagewidth now.

Paulo Cereda

12:24

@Nasser Split a PDF, for me, means spliting a document which contains several pages into individual documents. Perhaps you mean crop or trim PDF pages...

Nasser

@PauloCereda Yes I know. But I am asking something a little different. What I want is to split a PDF, which contains only one single page, but very looong page (say 70 inches), into multiple PDF pages each is 8.5 by 11 inch. So I can include these in my main document and not have to worry about different size pages, and worry about printing. Like this person is asking here apple.stackexchange.com/questions/12305/…

Paulo Cereda

@Nasser Ack. :) Still, it sounds trimming/cropping the same page in different regions to me. :) If I had to tackle this is some sort of "automatic" way, I would probably insert two tiny coloured marks in the PDF to indicate cropping boundaries, write a script to read the document as a colour matrix, define the regions to crop, calculate the offset and generate a set of pdfcrop invocations. :)

and now all pages have same width. That looong pdf file page also included with no zoom needed.   I just need to make sure I set print to "tile long page" when printing. I never used this option before. Will try it now to see how it works.

@DavidCarlisle Probably luaotfload, I don't think that OpenType makes it possible to construct fonts with endless loops. The font is probably doing something fishy too though.

@DavidCarlisle I think the only way this can happen is if a glyph has a list of variants, is not extensible and lists itself as last entry of the list. That would be a weird font but technically legal.

David Carlisle

@MarcelKrüger I think he's going to ask on luatex dev list in a bit (I made that plain example from a latex one) it works with the default font but the alternate integral shape selected with ss02 confuses it I tried looking in fontforge but don't really know enough what to expect

@MarcelKrüger I think it is doing this with ss02 (at least if I followed the numbers correctly), but I don't know who should catch it and how. Does it break in context too? (I don't have current context to test).

Paulo Cereda

@UlrikeFischer baa :)

Ulrike Fischer

@PauloCereda ;-)

Marcel Krüger

@DavidCarlisle luatex-dev? It's almost certainly off-topic there, but Hans probably reads it so it should be close enough.

David Carlisle

@MarcelKrüger yes that one I suggested it as it seemed more likely to get a knowledgeable response than just me and Karl:-) I wasn't sure at what level it was failing so that seemed as good as anywhere.

Marcel Krüger

14:13

@UlrikeFischer It almost certainly will break in ConTeXt too (I haven't teste it since I never worked out how to select font there without manual \font) The problem is that the small version of the integral sign is shared and therefore there is a small glyph which has two alternative larger versions. That's incompatible with LuaTeX, so the fontloader has to duplicate the small glyph to avoid this.

@DavidCarlisle Hi, just to keep you in mind for the future, I think a little update is
needed on (https://www.texfaq.org/FAQ-grffilenames) and (https://www.texfaq.org/FAQ-osf)

@PauloCereda It's a nice hat, I liked the red ones ...before there was a fedora :)

Paulo Cereda

@PabloGonzálezL of course Fedora is better. :)
