[edit]Problem with LibreOffice
[edit]Over several years I have written a large (> 60MB) .odt file using LibreOffice, with a lot of diagrams to the right adjacent to truncated lines of text to the left. A month or so ago, LibreOffice was unable to open the file (too big? inadequate computer? who knows?) but OpenOffice could, whereupon I split it into four portions, which LibreOffice can now open. But the portions have a specific formatting error which I've not been able to fix. Most, but not all, of the diagrams are now away from their text and have white space all the way to the left margin. Attempting to put them back alongside the text just moves the problem, with nothing to the left of the diagram. Living with this would involve quite a lot of rewriting, and the document would be much longer than wanted in a vertical sense. Can someone suggest a way of restoring the original format? ~2026-55003-48 (talk) 11:53, 13 October 2026 (UTC)
- Before mucking with OpenOffice, I would try: Open LibreOffice in safe mode and try to open the file. If that works, you have a bad user registry. If not, open LibreOffice, go into Tools>Options>Libreoffice>Memory and increase anything having to do with memory before opening the file. By default, LibreOffice won't us all your memory, so you have to give it permission to do so. If that doesn't work, go to Tools>Options>Libreoffice>View and disable hardware acceleration before opening the file. It is possible it is a display issue. If you get the file open, I strongly suggest compressing every image in the file. A common mistake is to put high resolution images in a file and scale them on the page, which does not reduce the size of the image file stored within the document. I also suggest learning how to use master documents. You make a master document which contains other documents. Then, as an example, every chapter can be a separate file, but the master document shows them as one single document. ~2026-46630-01 (talk) 12:01, 13 October 2026 (UTC)
- No doubt all good advice, but having now got my quarter-files via OpenOffice I wasn't planning on using it again. Whether or not the images get compressed, within LibreOffice is there a way to rectify the effect I described, and put them alongside the relevant text? ~2026-55003-48 (talk) 14:11, 13 October 2026 (UTC)
- To answer my own question, setting Wrap Before in the image properties seems to work. ~2026-55003-48 (talk) 15:00, 13 October 2026 (UTC)

[edit]The use of "ю" as a symbol for the exponent in some Soviet versions of ALGOL
[edit]Our article Scientific notation claims that
The ALGOL 60 (1960) programming language uses a subscript ten "10" [between the significand and the exponent of a number written in scientific notation], for example:
6.0221023. This presented a challenge for computer systems which did not provide such a character, so ALGOL W (1966) replaced the symbol by a single quote, e.g.6.022'+23, and some Soviet ALGOL variants allowed the use of the Cyrillic letter "ю", e.g.6.022ю+23. Subsequently, the ALGOL 68 programming language provided a choice of characters:E,e,\,⊥, or10. The ALGOL "10" character was included in the Soviet GOST 10859 text encoding (1964), and was added to Unicode 5.2 (2009) as U+23E8 ⏨ DECIMAL EXPONENT SYMBOL.
The part I have a question about is Soviet Algol variants allowing "ю" to be used for this purpose. This was originally added by NevilleDNZ in 2017 in special:diff/774402196, and I expect it is probably correct. But it has never had a source.
Since I don't read Russian, it's hard for me to track down sources about this. Can anyone find a source for this claim? –jacobolus (t) 03:43, 18 October 2026 (UTC)
- Aaccording to Google search, the Russian translation of the ALGOL 60 Report on Math-Net.Ru, "Сообщение об алгоритмическом языке АЛГОЛ-60" would confirm this. However, when trying to access this translation I get a timeout. It is quite conceivable – even likely – if it has been digitized, that the claimed "ю" is a scanno for 10. ‑‑Lambiam 10:15, 18 October 2026 (UTC)
- @Lambiam: - the link worked for me. I have reuploaded it to Dropbox at this public url. Please let me know when you have it, so that I can delete the Dropbox copy. ~2026-56016-87 (talk) 15:42, 18 October 2026 (UTC)
- Got it, thank you. I've added it to my private repository of ALGOL 60 Reports. ‑‑Lambiam 17:59, 18 October 2026 (UTC)
- The difference between the bitmap text of the scan and its OCR version (in the table in 2.5.2 on page 314) seems to confirm your scanno suspicion. ~2026-56016-87 (talk) 15:51, 18 October 2026 (UTC)
- That seems to be just a straightforward translation of the English report, which doesn't (as far as I can tell, as a non-reader of Russian) describe anything specific to Soviet ALGOL implementations. I think we'd need something like a reference manual for the specific one(s) using ю, or maybe some kind of document comparing different varieties of ALGOL, but I don't know how to find such a thing. –jacobolus (t) 18:41, 18 October 2026 (UTC)
- Here is the relevant part from the PDF (File:Algol-number-examples.jpeg):
- It's definitely '10', not a Cyryllic letter 'ю' there. --CiaPan (talk) 16:11, 19 October 2026 (UTC)
