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!

US, Taiwan, TSMC

CNN: Fear and resignation after ‘world’s most powerful company’ pays Trump a $100 billion ‘protection fee’ — edition.cnn.com/2025/03/13/tec

Taiwan Semiconductor Manufacturing Company (#TSMC) is investing $100 billion USD in the #USA. This is viewed by some as 'protection money" to keep the #US administration following its own law, Taiwan Relations Act, which requires them to provide #Taiwan with means to support itself in case of attack from the PRC mainland.

Replied to Kevin Karhan :verified:

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)...

We are glad to announce the next edition of the Free Silicon Conference (#FSiC) which will be held at IHP Microelectronics (Frankfurt an der Oder) on July 2, 3, 4 2025:

Please help us to spread the voice and to identify new open-silicon projects and new open-source Electronic Design Automation (EDA) tools.

To propose or suggest an idea just answer to this toot or write at fsic2025'at'f-si.org.

#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

#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.

@marcan nodds in agreement #Apple doesn't need to have backdoors in Hardware when their entire #iCould is backdoored and can be weaponized to brick devices.

  • OFC similar functionality can be achieved with #CompuTrace on #amd64-based #Laptops (i.e. #ThinkPads) and compared to that, #AMT + #ManagmentEngine is trivial to #exploit and should be considered real #backdoors (abeit "well meaning" in the sense of remote provisioning of entire fleets of devices, but still allowing to bypass the OS and offering DMA access to the CPU, so basically "#pwned")...

Either way, these are not inherent to the used #Silicon, but entirely #Firmware-based.

  • AMT for example requires a "#Intel #vPro" configuration with Intel-made Ethernet NICs (i.e. i2xx & i3xx - Series) with a Q- or C-series Chipset & supporting #UEFI, so most Systems with cheap #Realtek-NICs aren't exploitable straight-away, and even then it requires certain settings to work, so not an easy "#Pwn2Own" style exploitability...

Her book examines some of the ways that #Silicon #Valley #billionaires have become effectively complicit in enabling #autocracies to thrive,
agreeing to censorship on their platforms,
following the money.

She has been prominent among those writers shining a light on the ways that 🔸coordinated propaganda strategies in autocracies are fuelling division in the west.🔸

♦️Getting an American president who doesn’t like Nato in office is a lot cheaper than fighting wars♦️

“Of course, I don’t think either Trumpism or the Brexit campaign were foreign ideas,” she says.

“I mean, because I worked at the Spectator in the 1990s I knew many people who were anti-EU then
and who had grassroots deep in the English countryside.

But as we know, what the Russians do, and now others, 🔷they don’t invent political movements – they amplify existing groups.”🔷

In the case of #Trump, she suggests,
“he is clearly somebody who they cultivated for a long time.

Not as a spy or anything.
But they were offering him opportunities,
you know, he was trying to do [property] deals there [in Moscow].
And he’s been anti-Nato since the 80s.
He’s openly scorned American allies all of his life.
In one of his books, he talks about what a mistake it was for the US to be fighting the second world war.

👉So of course, the Russians would want someone like that,
because their aim is to break up Nato. 👈

❌And if they can help get an American president who doesn’t like Nato in office, that’s a huge achievement.
It’s a lot cheaper than fighting wars.”

New #recycling method makes #solar cells even more environmentally friendly
The primary ingredients of most #solarpanels are #silicon, #aluminum, and #silver, none of which is a major environmental threat. Solar panels also have a useful lifespan of decades, and the vast majority of those in existence are less than 10 years old, so waste hasn't even become much of a problem yet. And, even once these panels age out, recycling techniques are available.
