Meaning of :=

In SHA-2 I see "Initialize working variables to current hash value: a := h0" In this instance, what exactly is meant by := ? Does it mean "equals," or "is defined as," or "is set to the value," or what? In my math and computer science courses long ago I do not recall seeing exactly this "colon equal" notation.

It would mean set to the value. The symbol was introduced in ALGOL 58, so that the plain "=" would mean comparison. See Assignment (computer science) for our article. Graeme Bartlett (talk) 01:58, 29 April 2018 (UTC)[reply]

Find on Page /part of word

How do you search within a page using an iPhone for “ark” with words like “park”. Find on Page doesn’t find them. 120.16.153.99 (talk) 05:23, 29 April 2018 (UTC)MBG[reply]

hosting PDF files

Hello everyone. I have a YouTube series of mathematics videos, and I now have a series of PDF documents that support the videos. I would like to make the PDF files available to my viewers for download. What options do I have to do this? In principle I could put them on github (the software that creates the PDFs, mostly R}, is on a github repo), but I don't think github is appropriate for non-human-writable formats such as PDF. Can anyone advise? Robinh (talk) 06:03, 29 April 2018 (UTC)[reply]

You can upload pdfs to Commons if they are under a free license. Ruslik_Zero 16:51, 29 April 2018 (UTC)[reply]
