fronde contre l'Éducation nationale 'gros' contrat à Microsoft

> Hexatrust, l'association professionnelle des acteurs français et européens de la cybersécurité et du cloud de confiance, pousse un coup de gueule contre le ministère de l'Éducation nationale qui vient d'attribuer un marché public de 74 millions € à Microsoft. De son côté, le député Philippe Latombe demande son annulation.

Hey hey, you thought there be no #nakeddiefriday today? Here we go!

Today's entry is an Infineon/Siemens SAB-C167CR-LM, a microcontroller based on the C166 core. The die is in pleasant-looking pastel colours. :-) The die has pin 1 in top left corner. I'll do a short thread.

Many thanks to @debauer for supplying the samples!

I'd rather want a #honest #MSRP than a effectivley unavailable one.

  • OFC I don't expect a board partner to accept a margin of just $4, but it would be easier to accept a 5% higher MSRP than having no stock at MSRP.

And yes, I blame #AMD, #nvidia and #intel doing #Greedflation against #consumers because I'm very certain they don't sell #silicon at cost for a fixed price per unit depending on the order size, but rather charge a cut of the sold model (similar to #ARM does nowadays for their #licensing)...

#OrganicPhotovoltaics: the path to lightweight, flexible and transparent #SolarCells

Researchers at #HiroshimaUniversity are creating organic photovoltaics that are sustainable and offer many benefits over traditional #silicon-based solar panels.

"Itaru Osaka’s story with organic photovoltaics began as a PhD student working in the research group of Hideki Shirakawa at the University of Tsukuba in Japan. In the 1970s, Shirakawa, along with American scientists Alan Heeger and Alan MacDiarmid, found a way to make plastics that can conduct electricity — a discovery that won them the Nobel Prize in Chemistry in 2000.

"These days Osaka has his own research group at Hiroshima University that is working with these ‘conjugated polymers’ to make carbon-based, ‘organic’ photovoltaic cells. In contrast to typical silicon-based cells, which are relatively bulky, heavy, rigid and opaque, the organic alternatives are flexible and transparent enough to be placed where existing cells cannot, such as on the walls of buildings, the glass of greenhouses and even on the sides of tents.

"Significantly, their fabrication is expected to be cheaper and consume less energy than silicon-based photovoltaics."

Years ago, I was asked to make a print for a missing element in a gallery show of the Periodic Table Printmaking Project, which gathered prints by different artists for each element . This small linocut represents the chemical element Silicon, with its diamond cubic crystal structure shown in silver. Its symbol, atomic number and a couple of its forms are shown in lilac. Silicon is common in the Earth’s crust 🧵1/n

As described, this small linocut represents the chemical element Silicon, with its diamond cubic crystal structure shown in silver as a collection of balls. Its symbol, atomic number and a couple of its forms are printed on top of the silver layer in lilac. This shows quartz crystals in each corner. Four radiolarians circle the symbol for Silicon on the periodic table. The print is one of an edition of 14, each 6” x 6” (15.2 cm x 15.2 cm) printed on Japanese kozo paper.

Plans for the weekend: Terminate Prime, Audible and all Google. Move backups to S3 alternative in EU. Enjoy the dogwalk with my 15 year old furry friend to the max. I still love #America and Americans, but it's time to divorce the #silicon #valley bros as best I can. european-alternatives.eu/de/pr #broxit

Going live in under an hour for the open source silicon stream #6!

I plan to do a low voltage experiment to see what happens with a design running with a low core voltage.

We have recently got some new chip decap images from Texplained, so I'll take a look at them.

And following on from stream #4 I'll take a look at a level shifter designed by Sylvain Munaut

#Solar panel production refers to the entire lifecycle of solar panels, from raw material extraction to #manufacturing processes and end-of-life considerations. #Environmental impact encompasses the effects on #ecosystems , #biodiversity, energy consumption, #waste management, and more. Life cycle assessment is a methodology used to evaluate the environmental impacts of a product throughout its entire lifecycle.
The production of solar panels requires the extraction of materials like #silicon, #silver , and #aluminum . The #mining and processing of these materials pose significant environmental consequences, including habitat destruction, soil #erosion , water #pollution , and #greenhouse gas #emissions .
Solar panel manufacturing involves multiple steps, including wafer production, cell fabrication, and module assembly. Each step requires #energy and emits greenhouse gases. Energy-intensive processes like wafer production contribute to the overall #carbon footprint of solar panel production.
As solar panels reach the end of their lifespan, proper waste management becomes crucial. The disposal of decommissioned panels can lead to environmental contamination and potential health risks. However, there are emerging solutions such as recycling and resource recovery to mitigate these challenges.
By addressing the challenges associated with raw material extraction, manufacturing processes, waste management, and #ecosystem impacts, we can work towards minimizing the negative consequences....
- the topic of the overall ecological burden of #renewables seems to be a key one in considering a realistic #emission-free #economy (unless it is just an alibi for pushing dirty processes to other countries). The article is quite short and it only opens the topic - it would be useful to know some hard data on this topic. May be from the sources the article refers to, or I'd be glad for other tips from someone.

EurekAlert!From root to shoot: How silicon powers plant resilienceA breakthrough study reveals that the Shoot-Silicon-Signal (SSS) protein plays a crucial role in managing silicon uptake and distribution in rice and other grasses. This study sheds light on how SSS helps plants adapt to environmental stresses. Understanding the role of silicon could provide valuable information on crop resilience and solutions to enhance agricultural productivity and sustainability, especially in the face of climate change.
