Das ist eine sehr coole #Podcast-Episode über die #PDA-Zeit mit #Palm, Apple #Newton und Co.

Ich war auch begeisterter Palm-Nutzer und weine vielen Features von #DateBk6 nach, die ich seither nirgendwo mehr gesehen habe (außer mein Nachbau davon mit #Orgmode).

Für Nostalgiker sehr empfehlenswert. 👍

Edit: mein Favorit damals: Palm #Tungsten T3 mit DateBk6 (extra gekauft). Das war damals wirklich 🤯 gut.

Edit2: https://inlovewithpda.com/ wird dort erwähnt und ist sehr cool gemacht.

Africa: Inside Rwanda's Tungsten Mine Which Is the Leading Producer in Africa: [New Times] It is a busy Monday at Nyakabingo Mine in Rulindo District as over 2,000 workers engage in various roles, from office duties to mechanised underground mining in search of wolframite, the host mineral for tungsten. http://newsfeed.facilit8.network/TJJjV4 #Rwanda #Tungsten #Mining #Wolframite #Africa

China curbs exports of five metals. What are they used for?

China has announced sweeping export restrictions on five metals used in the defence, clean energy and other industries.

Here is what you need to know about them:

#China
#tungsten
#indium
#bismuth
#tellurium
#molybdenum

Tungsten is an ultra-hard metal — in terms of strength, outdone only by dia-
monds — and is primarily used in the production of goods including artillery
shells, armour plating and cutting tools. About 60 percent of its US consumption goes to making tungsten carbide, a highly durable material used in construction, metalworking, and oil and gas drilling.

Indium is a vital part of phone screens and TV displays via a refined product
called indium tin oxide. A separate indium product is also used in fibre-optic technology. The expansion of fifth-generation (5G) cellular networks has led to greater demand for indium.

Bismuth is used in solders, alloys, metallurgical additives, medications and
atomic research. The US ceased production of primary refined bismuth in 1997 and is highly import reliant, according to the USGS.

Tellurium, usually a byproduct of copper refining, is used across metallurgy and in solar panels, memory chips and other products. Most US products requiring tellurium relied on imports of the metal.

Molybdenum is primarily used to strengthen and harden steel alloys, making
them more resistant to heat and corrosion. It is also used in lubricants, pigments and as a catalyst in the petroleum industry.

#Trump’s #tariffs, which slap a 10% #tariff on all Chinese goods, went into effect after the #US & #China did not strike a deal by 12:01AM Tues. China’s response further escalates #trade tensions between the world’s 2 largest economies.
 China’s Ministry of #Finance announced 15% tariffs on #coal & #LNG, & 10% tariffs on crude #oil, #agricultural machinery & some #vehicles. The Ministry of #Commerce announced export restrictions on materials such as #tungsten & #sanctions on 2 US companies.
