[Focus on the #EnVision mission] Why have #Venus and Earth evolved so differently? This is the question to be answered by the EnVision #SpaceMission of the European Space Agency - ESA, scheduled for launch in 2031.

To this end, the European #probe will carry several instruments - including an imaging #spectrometer, to which IRAP staff are contributing. Observations will be made in the UV and IR domains, in order to monitor temporal variations in #surface temperature and gas concentrations within the #atmosphere - and thus gain a better understanding of interactions between the Venusian atmosphere and surface.

#AliExpress / cheap #Chinese goods / #questionable sellers, part 37:

1. Order #rechargeable 3-speed folding desk #fan.
2. Receive different version of same fan - no #electronics, no #battery, just a USB lead, it runs at one speed when plugged in, unplug it to turn off.
3. File "item not as described" ticket with photos clearly showing it's the wrong item.
4. AliExpress rejects ticket, the human who spent 0.3s reviewing it didn't read it and just clicked "#reject".
5. Edit #photos, adding big red "NO BATTERY HERE -->" and "NO ELECTRONICS HERE -->" etc and resubmit ticket.
6. AliExpress accepts claim this time. Get refund.
7. Place order for same rechargeable fan from different #seller.
8. Receive fan. #Charge. Give to partner.

"It turns off after a few seconds", she says.

Take it apart. Examine the circuit board, #probe it various ways, all looks good. #Measure #voltages. Manually #power the fan and see it draws half an #amp. See the suspiciously undersized lithium-ion #cell and think "they didn't just #cheap out so much that the thing doesn't work, did they?"...

Yup. The plastic casing has a slot & tabs arrangement inside sized for an 18650 cell, but they've got a much smaller cell in there with some padding to keep it in place. It's a 14500.

When the fan's on, the load is too much for the cell. The voltage drops enough that the little 3-speed management #chip thinks the cell is flat, and it turns off.

Put in a good 18650, runs like a charm.

Sheesh.

Federal judge rolls back key #civil #rights protections in Louisiana’s ‘#sacrifice #zones’

The decision could open the door for other industry-friendly states to follow suit

James Cain, a federal judge in Louisiana who was appointed by president Trump,
decided to
block the Environmental Protection Agency and the Department of Justice from pursuing enforcement actions based on
“#disparate #impacts”
— or the idea that a 🔸regulation might disproportionately harm one group of people over another. 🔸

A provision of the landmark Civil Rights Act of 1964 known as #TitleVI allows federal agencies to take action against state policies and programs that discriminate on the basis of race, color, or national origin.

Since the EPA’s founding in 1970, however, the agency allowed most of the Title VI complaints that it received to languish without resolution.

In 2015, a coalition of community groups in Louisiana,
with the assistance of the public-interest environmental law organization #Earthjustice,
sued the agency for this practice and won.

Five years later, after president Biden took office,
✅federal regulators finally began addressing the civil rights complaints they received and
✅the EPA announced a civil-rights #probe into #Cancer #Alley
— a stretch of land on the lower Mississippi River between Baton Rouge and New Orleans where
💥over 150 chemical plants pump cancer-causing chemicals into the air of predominantly Black communities💥
— marking 💪🏽a new phase of the agency’s use of Title VI.

The federal government was making significant progress with Louisiana officials in their Title VI negotiations:

Cancer Alley residents’ principle demand
— that state regulators assess whether a community is already exposed to disproportionately high levels of pollution before permitting a new project there
— had made it into a draft resolution document.

❗️But at a certain point in the process, sources told Grist, the talks broke down.

⚠️Then in May 2023, #Jeff #Landry, then the attorney general (and now the #governor) of Louisiana,
filed a lawsuit against the EPA.

On the basis that the agency was overstepping its authority, 💥Landry’s suit challenged not only the EPA’s use of Title VI to regulate pollution in Louisiana,
but 💥also the very legal justification of "#disparate-#impacts" regulation, 👉which reaches thousands of programs across the country
👉and can be used to adjudicate decisions as varied as where a new highway can go or whether a housing practice is discriminatory.

🆘Advocates worried that the lawsuit had the potential to unravel decades of civil rights law.

Judge Cain’s final judgment concurs with Landry’s argument.

🔥In effect, the ruling will make it impossible for the EPA to pursue enforcement actions based on disparate impacts
— but only in Louisiana.

Cain’s judgment comes in the same week as ❗️the EPA’s new Title VI guidance,
which urges state and local regulators to establish safeguards that protect their constituents against discrimination.

I played around with #probe-rs last week, a nice development tool for #embedded #rust. I use #neovim, but didn't found a good config for nvim-dap, so, although being a #lua noob, I started to look on how to configure it.

Basic configuration was not that complicated. But getting access to RTT working was in interesting dive into the typescript code of the vscode plugin for probe-rs and the nvim-dap plugin.

I added the result to the probe-rs doku and nvim-dap wiki if you are interested.
