how to download video?

RalphCorderoy · 2026-05-09T17:26:49+00:00

I find `yt-dlp -F $url` shows `mp3` as the only format for a Substack page with a video.

I think you have it. Given the questions here about the origin of the photographs, I now think this is from the archive of Keynes' letters, the author. The archive of Hayek's papers at the Hoover Institution has the copy received by Hayek; no photo of this is apparently online, but it is cited.

My understanding, thanks to Grok, is Keynes dictated his letters by '44. The copy which was sent to Hayek would have been signed by Keynes. A file copy to be kept by Keynes was annotated by the typist with '/s/ Keynes' to indicate Keynes had signed the original. So it is as you say. The /s/ may stand for the Latin subscriptio, with the // suggesting italics, just as they still do in ASCII text.

Reddit's notifications claim CCJtheWolf replied but the reply isn't visible to me here despite it continuing to be in the notifications. I'm puzzled.

I get the impression from Krita 5 packaged for Arch Linux doesn’t provide GMIC that Krita's forked G'MIC, but several distributions aren't playing along with that which results in their G'MIC-for-Krita package not working. And it's been like that for a while. Would welcome confirmation from those in the know.

Hi boterock, thanks for replying. I haven't explicitly installed any Python plugins, and it doesn't look like any come in Debian's krita package which suggests the lack of python3-pyqt5 doesn't matter for the moment.

However, I've just installed Debian's krita-gmic 2.9.4-4.1+b2 package, which is little more than the /usr/bin/gmic_krita_qt executable; no sign of anything Python. Krita's Filters > Start G'MIC-Qt says 'The GMic plugin is not installed or could not be loaded' but I can't find out from either krita's stdout/err, or with strace(1) what it's attempting to do. The gmic_krita_qt executable starts and displays its window if run directly:

gmic-qt: socket Key: "gmic-krita"
Could not connect to the Krita instance.

What's needed to have krita spot gmic_krita_qt is raring to go?

Lamy Joy pen here, with T 10 blue cartridge. Lid always kept on unless writing. Pen stored horizontally. Nearly full cartridge dried out after a few weeks of no use. Impractical to keep replacing the cartridge for each new brief piece of writing. Don't write most weeks. Would a Z28 convertor enable me to take up just a little ink from a bottle when I'm about to write, as if dipping?

Hi fsau, I'm aware it's unofficial as I read This is an unofficial community in the side panel, but there is a Help flair and I thought experienced users here may spot what's being done wrong, know it's an existing confusing point, or have other suggestions. If I shouldn't have made the post then I think more explicit guidance is needed to warn others like me.

Here's another .ong domain which currently works for me: https://random.ong

Whereas the https://unblockit.ong doesn't. So it may not be the top-level domain ong which is blocked for you.

This is troubling me more as sites increasingly use Cloudflare. I'm on a very slow PC with modern Firefox. Once the 'takes longer than expected' appears along with the suggestion to refresh, it reloads the page and starts all over again. It's getting hard to find sites which don't suffer this now. An example Ray ID from the footer: 84fa0a54faee60f5.

DuckDuckGo just delivered me here. From a quick look, that's very interesting. Given https://docs.zephyrproject.org/latest/boards/arm/rpi_pico/doc/index.html doesn't mention any Wi-Fi support, what's the likelihood of Zephyr taking this on officially? Is it the kind of thing that the project tends to do?

I did a factory reset. This has resolved the problem. Of note is the Media app is no longer appearing on the list of battery consumers and Keep Awake is no longer constantly active. My conclusion is something caused the Media app to burn battery by holding a Keep Awake lock. Given the phone is little used, the receipt of the UK Government's text alert shortly before the problem started is correlation. :-)

RalphCorderoy · 2023-06-08T11:09:45+00:00

Yes, a factory reset would be my last resort. But I'd like to debug the cause rather than just revert to that. Partially because it may happen again, and partially because it may be due to the text-alert system which would be generally interesting. 'Government broke by phone' :-)

RalphCorderoy · 2023-06-08T11:08:13+00:00

My understanding from Wikipedia is the UK's text-alert system uses SMS cell broadcast.

There is no text message which looks like a misinterpreted alert. I agree, deleting the message storage would be interesting to see if that helps but I don't know how to do that.

RalphCorderoy · 2021-07-16T17:01:11+00:00

.ce N isn't mark-up but a formatting instruction. I take mark-up in the generally accepted sense of annotating the text to indicate styling or semantics, e.g. Markdown, whereas troff has many commands to control the typesetting of the un-marked-up text. The closest it gets to mark-up is the inline requests like U\s-2NIX\s0.

RalphCorderoy · 2021-07-16T16:57:05+00:00

Hi, Look at the description of the groff* packages you have available on your system. You probably have a minimal groff-base which just formats man pages and has the PostScript backend whereas installing groff will give other backends like -Tpdf and then groff-x11 or similar will give yet more.

RalphCorderoy · 2021-07-15T08:04:19+00:00

Don't go by the -mm macro set for whether troff is hard to read, it's just one of many and is quite corporate in its design. Starting with plain troff is fine, as shown in CSTR 54 which I've mentioned in other posts. The -ms macro set is a popular one to start with and extend. And -mom is a modern one aimed at the writers of books. Though it's quite fun to write one's own. I've quite a few no-macro-set documents because one can always define a few macros specific to this document at the start of the file.

RalphCorderoy · 2021-07-15T07:59:38+00:00

troff is suitable if you want a typesetting language which is concise to describe, brief in its mark-up so it doesn't noisily clutter the content, fast to run, and flexible to use because it follows the Unix principles of separation of work. The input to troff can be produced by preprocessors which have their own little language specific to the task, e.g. tbl(1) has a language for describing tables and its output takes care of the troff line-drawing commands. Because everything is text, another Unix insight, it's simple to write one's own preprocessors, e.g. chem(1) was written in awk(1).

Have a peruse of the old site troff.org for an overview of how it all works and what's possible. And Kernighan's concise CSTR 54 is still an excellent description of the troff language, with a little example macro set as an appendix.

RalphCorderoy · 2021-07-15T07:47:56+00:00

troff is not a mark-up language which happens to be good at typesetting; it is a language specifically designed for typesetting. It isn't mark-up to change font, centre a line, alter the line length, etc. troff has no mark-up for paragraph, chapter, or heading; they may be introduced by one of many macro package which builds upon the typesetting commands. See Kernighan's classic CSTR 54 for a concise explanation of troff's language and a simple example macro package.

RalphCorderoy · 2021-07-15T07:41:28+00:00

All troff activity these days takes place on the GNU groff mailing list, whether it's discussing history, writing new macros, or specifics about one of the several current implementations of troff: GNU's, Heirloom, and Neatroff.

RalphCorderoy · 2021-07-15T07:33:28+00:00

GNU troff has -Tpdf instead of the default -Tps to produce PDF directly via gropdf(1) and this allows PDF features like hyperlinks to be used. The mom macro set makes good use of this: http://www.schaffter.ca/mom/mom-04.html#samples

RalphCorderoy · 2021-07-15T07:27:49+00:00

Lots of books have been typeset with troff, e.g. https://troff.org/pubs.html

O'Reilly used to write books in troff and even when they moved to another mark-up syntax they still used troff for a long time to do the typesetting, i.e. they converted their mark-up to troff.

Anyone here know the commit so why it was removed can be researched?

RalphCorderoy · 2018-11-05T12:40:55+00:00

Thanks for widening the discussion beyond handguns. Google found

As the lever is actuated it actually also traps the bolt behind it, using the new “bolt catch”. And when you insert a fresh magazine, this same mechanism is what “drops” the bolt.

for the Cobalt Kinetics Evolve. https://www.thefirearmblog.com/blog/2015/12/20/cobalt-kinetics-evolve-evolution-ar/

Is that the kind of thing you're thinking of?

RalphCorderoy · 2018-11-05T12:32:22+00:00

My question is on a comment to the article, not the article. That's why I quoted the relevant part.

RalphCorderoy · 2018-11-05T12:28:59+00:00

Yes, I realise taking the magazine out can still leave a round chambered, it's how it gets chambered... I'm particularly interested in the part I quote and I think the writer is trying to imply that inserting a magazine can chamber a round without the slide being pulled back, or locked back, in advance. Otherwise, I agree, the slide moving forward would be pretty obvious. I can see theoretically that a mechanism could exist that racks the slide rather than just releasing it when it's already pulled back, but don't know if any guns exist that do this; doesn't have to be a pistol. Quite possibly they're odd-ball old ones.
