Thanks mnalis for posting the fix on the Github issue thread. I had spent time fruitlessly trying the Nextcloud app settings, permissions settings, and other stuff, but nothing had any effect - auto upload would not trigger.

Under Android Settings / User & accounts / Nextcloud / Sync the options File sync was OFF! I toggled it ON and the thing started uploading photos immediately.

This is just a quick-and-dirty one-liner. I was compiling beamer slides, and for some reason the TikZ-generated PDF figures contained two pages under some circumstances. This way we can quickly see whether just some PDF files or all of them suffered a problem:

$ find figure/ -type f -name "*.pdf" -exec pdftk "{}" dump_data \; | grep NumberOfPages | awk '{print $2}'
1
1
1
1
1
1

(in this case they were all one page long).

A very nice resource!

I found it while reading up on presentation software (pdfpc and such).

Det första föredraget av Petter Falk (doktorand på Karlstads universitet) var riktigt bra. Man får hoppas Trafikverket lyssnar.

Really nice work by Steve Byrnes. Very useful.

I keep getting annoyed by Doodle. In this latest example, it proved impossible to change the shown "name" as guest user once my answer was submitted, despite it being possible to change everything else, or even decline. (I wanted to make use of the "name" field to include a single-word message to the organizer.) And when logged in the name field never even showed up during the answer flow.

Alternatives to Doodle

• https://framadate.org/abc/en (FOSS, by the well-known French organization Framasoft)
• https://datumprikker.nl (not FOSS, but perhaps convenient since it offers Google and Apple apps). Don't forget to change to English in the menu.

African farmers on average use the least fertilizer per acre in the world and have some of the lowest yields, particularly for corn and other grains that provide the bulk of the continent’s calories. As a result, despite having 60 percent of the world’s arable land, almost half the countries in Africa depends on imported wheat from Russia and Ukraine, with 14 African countries getting more than half their wheat from the two warring nations.

avtal med företaget ArkivIT om drift och support av ett e-arkivsystem baserat på programvarorna Archivematica och AtoM (Access to Memory)

Hösten 2021 gick det Enskilda e-arkivet med Arkiv Sörmland i spetsen in i slutfasen för E-arkivportalen. Tanken är att portalen ska nyttjas av föreningar som vill arkivera digitalt material som i första hand tillkommit digitalt. Det kan röra sig om hemsidor, sociala medier, mailkorrespondens, avtal, räkenskaper, fotografier, videofiler, och mycket mer.

I takt med att prisjakt försämras och dag för dag blir mindre användbart (senaste försämringen var Cloudflare "säkerhetskontroll" när man klickar på en produktlänk för att "gå till butik"...) blir det tyvärr nödvändigt att hålla en egen lista över återförsäljare och dylikt.

Let's say you have a very large Zotero library, from which you export a likewise large BibLaTeX file, say full-library.bib.

In your document you load that large BIB-file (because that's easy), \addbibresource{full-library.bib}, but naturally cite only a subset of works.

Now you want to share the source code for this document with someone else, and provide them with a BIB-file so they can recompile it if they wish. Can we produce a BIB-file containing only the entries that were actually cited in the document?

Yes, we can. biber has built-in support for this scenario. Just make sure your latest compilation produced a proper .bcf file, then:

biber --output_format=bibtex --output_resolve document.bcf

which will create document_biber.bib, a properly formatted BibLaTeX BIB-file containing only the subset of works from your library that were actually cited in this document.

I'm afraid I don't remember where I learned this.

This is cool, research data on SND is now indexed and findable via the Swedish data portal.

At least not reliably. What is going on?
I can see new messages in other IMAP clients, such as K9 Mail. But Thunderbird shows no new messages, despite F5 or Shift+F5.

TB never behaved this way before (102). New messages were automatically fetched.

Going offline by clicking the icon in the lower left makes TB prompt if we first want to download all messages; the blue list in the status bar keeps pulsing forever, but no new messages are fetched.

Restarted into "troubleshoot mode" - now it works. Ok, so could it be a problem with one of my extensions?

Seems not - I restarted Thunderbird with all extensions disabled, and it still will not fetch any messages from any email account. I have no time for this. I am reverting to v102 from my profile backup (always good to have a backup of your profile!).

On the political arena, the Egyptian government has established a "National Council for Green Hydrogen and its Derivatives", chaired by the prime minister and counting among its members: the minister of electricity and renewable energy, the minister of petroleum and mineral resources, the minister of justice, the minister of planning and economic development, the minister of finance, the minister of environment, the minister of housing, the minister of utilities and urban communities, the minister of transportation, the minister of trade and industry, the minister of irrigation, the minister of state for military production, the chairman of the Suez canal authority, the chairman of the general authority for the Suez canal economic zone, the first assistant to the prime minister, the CEO of the general authority for investment and free zones, and the executive director of Egypt's Sovereign Fund.

I must admit I wonder what the point is forming a special council if it includes what appears to be most of the government. No word on permanent members from industry or academia.

On the council's first meeting an executive committee was formed (unclear who its members are) and tasked with speeding up the approval process for green hydrogen projects and to entice companies to invest in such projects, using investment incentives such as 33%–55% less tax, and exempting most equipment and supplies from VAT tax, an exemption from real estate tax on buildings, and waived fees for registering the companies in Egypt.

To date, the government has signed memoranda of understanding (MoU) with among others ACWA Power (Saudi Arabia), Benchmark Alliance (?), China Energy company, the national holding company for chemical industries (the Egyptian one, I assume), DAI global company (Germany), OCIOR Energy company (India), Voltalia-TAQA alliance (sounds Italian?), and British Petroleum.
The stated ambition of the government is to produce green hydrogen at 1.7 USD/kg by 2050 and to capture 8% of the global market. The government expects that total foreign investment into green hydrogen projects to reach 81 billion USD by 2035.

The national strategy for green hydrogen is yet to be published, as far as I can tell.
