Welcome to The Cruelest Day: Tuesday February 11, 2025, and National Peppermint Patty Day.  I can’t show a picture (copyright issues!) but here’s some information from Wikipedia, where you can find a drawing from the Peanuts strip:

Peppermint Patty is a fictional character featured in Charles M. Schulz‘s comic strip Peanuts. Her full name, very rarely used in the strip, is Patricia Reichardt. She is one of a small group in the strip who live across town from Charlie Brown and his school friends (although in The Peanuts Movie, Snoopy in Space, and The Snoopy Show she, Marcie, and Franklin live in the same neighborhood and attend the same school). She has freckles and “mousy-blah” hair, and generally displays the characteristics of a tomboy.

Charles M. Schulz modeled Peppermint Patty after a favorite cousin, Patricia Swanson, who served as a regular inspiration for Peanuts. Schulz had also named his earlier character Patty after Swanson, and he coined his well-known phrase “Happiness is a Warm Puppy” during a conversation with her in 1959. Swanson’s roommate Elise Gallaway served as the model for Peppermint Patty’s best friend Marcie. In later years, especially after lesbian groups began identifying with Peppermint Patty, Schulz downplayed the fact that the character was based on Swanson to protect her privacy.

In one interview, Schulz stated that he coined Peppermint Patty’s name after noticing a dish of peppermint patties in his house and deciding the name was so good that he should use it before another artist thought of the same joke. He created the character design to fit the name. Peppermint Patty debuted in the strip of August 22, 1966.  In 1972, Schulz introduced the character’s last name, Reichardt, which he borrowed from the last name of his secretary, Sue Reichardt, whose favorite character was Peppermint Patty.

It’s also Get out Your Guitar Day (I have a Martin that I no longer play), International Day of Woman and Girls in Science,  and National Latte Day. Here’s mine from yesterday (Puerto Rican coffee courtesy of Divy):

*Trump is about to intensify his trade war by levying tariffs on steel and aluminum from every country, including Canada and Mexico (article archived here):

President Trump is poised to move forward with sweeping tariffs on foreign steel and aluminum on Monday, re-upping a policy from his first term that pleased domestic metal makers, but hurt other American industries and ignited trade wars with allies on multiple fronts.

The 25 percent tariffs that the president said he would impose on foreign steel and aluminum will be welcomed by domestic steelmakers, who argue they are struggling to compete against cheap foreign metals. As they did during Mr. Trump’s first term, U.S. metal makers have been lobbying the administration for protection, and Trump officials agree that a strong domestic metal sector is essential for U.S. national security.

But the tariffs will invite plenty of controversy. They are likely to rankle America’s allies, like Canada and Mexico, who supply the bulk of U.S. metal imports. And they could incite retaliation on U.S. exports, as well as pushback from American industries that use metals to make cars, food packaging and other products. Those sectors will face significantly higher prices after the tariffs go into effect.

That’s what happened in Mr. Trump’s first term, when he slapped 25 percent tariffs on foreign steel and aluminum. While he and President Biden eventually ended up rolling back those tariffs on most major metal suppliers, they were often replaced with other trade barriers, like quotas. Studies have shown that while the measures helped U.S. metal makers, they ended up hurting the broader economy, because they raised prices for so many other industries.

And of course that’s what’s expected. Tariffs are no good for anybody, and ultimately the consumer pays the price. Further, among his other unconstitutional acts, the NYT reports that Trump is contemplating running for a third term!:

Just eight days after he won a second term, Mr. Trump — whose supporters attacked the U.S. Capitol on Jan. 6, 2021, in an effort to prevent Joseph R. Biden Jr.’s victory from being certified — mused about whether he could have a third presidential term, which is barred by the Constitution.

Since then, he has floated the idea frequently. In public, he couches the notion of staying in office beyond two terms as a humorous aside. In private, Mr. Trump has told advisers that it is just one of his myriad diversions to grab attention and aggravate Democrats, according to people familiar with his comments. And he has made clear that he is happy to be past a grueling campaign in which he faced two assassination attempts and followed an aggressive schedule in the final weeks.

The third-term gambit could also serve another purpose, political observers noted: keeping congressional Republicans in line as Mr. Trump pushes a maximalist version of executive authority with the clock ticking on his time in office.

The man is insane! (But we knew that already.) This, like the prohibition of birthrights, is destined to sink like a lead balloon. The Supreme Court wouldn’t allow anything like this, for it’s a clear violation of the Consitution.

*The WSJ reports that, in violation of international law, Ukrainian prisoners of war are now subject to unlimited violence  and torture in Russian prisons, with no restrictions on what can be done to them.

In the weeks after Russia invaded Ukraine, the head of St. Petersburg’s prisons delivered a direct message to an elite unit of guards tasked with overseeing the influx of prisoners from the war: “Be cruel, don’t pity them.”

. . . Those meetings set in motion nearly three years of relentless and brutal torture of Ukrainian prisoners of war. Guards applied electric shocks to prisoners’ genitals until batteries ran out. They beat the prisoners to inflict maximum damage, experimenting to see what type of material would be most painful. They withheld medical treatment to allow gangrene to set in, forcing amputations.

Three former prison officials told The Wall Street Journal how Russia planned and executed what United Nations investigators have described as widespread and systematic torture. Their accounts were supported by official documents, interviews with Ukrainian prisoners and a person who has helped the Russian prison officials defect.

. . . . Pavel Afisov, who was taken prisoner in the city of Mariupol in the initial months of the war, was among the first Ukrainian prisoners detained in Russia. For 2½ years, the 25-year-old was moved from prison to prison in Russia before being released in October of last year.

He said beatings were the worst when he was transferred into new prisons. After arriving at a penitentiary in Russia’s Tver region, north of Moscow, he was led by guards into a medical examination room and ordered to strip naked. They shocked him repeatedly with a stun gun while shaving his head and beard.

When it was over, he was told to yell “glory to Russia, glory to the special forces” and then ordered to walk to the front of the room—still naked—to sing the Russian and Soviet national anthems. When he said he didn’t know the words, the guards beat him again with their fists and batons.

The violence served a purpose for the Russian authorities, according to the former guards and human-rights advocates: making them more malleable for interrogations and breaking their will to fight. Prison interrogations were sometimes aimed at extracting confessions of war crimes or gaining operational intelligence from prisoners who had little will to resist after they suffered extreme brutality.

The former guards described a staggering level of violence directed at Ukrainian prisoners. Electric shockers were used so often, especially in showers, that officers complained about them running out of battery life too fast.

One former penitentiary system employee, who worked with a team of medics in Voronezh region in southwestern Russia, said prison guards beat Ukrainians until their police batons broke. He said a boiler room was littered with broken batons and the officers tested other materials, including insulated hot-water pipes, for their ability to cause pain and damage.

The guards, he said, intentionally beat prisoners on the same spot day after day, preventing bruises from healing and causing infection inside the accumulated hematoma. The treatment led to blood poisoning and muscle tissue would rot. At least one person died from sepsis, the officer said.

Many of the guards enjoyed the brutality and often bragged about how much pain they had caused prisoners, he said.

Well, this is close to how the Nazis treated Soviet prisoners of war, though it’s not quite as bad (the Germans often shot them or starved them to death). But it’s a war crime, and I doubt that Ukraine is doing anything like this.  Remember when Trump said he’d stop the war in Ukraine on “day 1” of his administration?

*Two piece of news from the Hamas/Israel war.  First, Hamas has suspended both the release of hostages and the cease-fire, blaming Israel for violating their agreement:

Hamas announced on its Telegram account on Monday that it is canceling the release of hostages on February 15 until further notice due to an Israeli violation.

Egyptian mediators fear that the statements will lead to a breakdown of negotiations. At the same time, Hamas told US mediators that the ceasefire was no longer in place due to Trump’s comments about displacing Palestinians.

The Hostages and Missing Families Forum said, following the announcement, that it has reached out to all countries mediating the agreement, demanding “swift assistance in finding an immediate and effective solution to restore the implementation of the deal.”

“We call on the Israeli government to refrain from actions that endanger the execution of the signed agreement and to ensure its continuation, securing the return of our 76 brothers and sisters,” the statement continued.

“The hostages are out of time, and they all must be rescued from this nightmare urgently,” the forum added.

They said they have officially contacted the government and the intelligence coordination unit to “clarify the situation and provide updates to all concerned families who fear for their loved ones’ fates.”

Prime Minister Benjamin Netanyahu is consulting with top security officials in light of Hamas’s announcement and intends to move the security cabinet meeting on Tuesday to the early morning hours.

One Israeli official told The Jerusalem Post that, in his view, Hamas did not attempt to sabotage the deal in its latest statement.

What is going on here? Hamas is complaining that Israel is not delivering enough goods to Gaza and not allowing Gazans to return to their homes in northern Gaza.  Neither claim is true: Gazas who go north and find their homes in ruins are simply heading south again.  Malgorzata suspects that this is a tactic that Hamas is using to try to wheedle more out of Israel than was agreed.  We will know on Saturday, if more hostages are not handed back to Israel, if Hamas is really  breaking the agreement. If so, then all hell may break loose.

*Also, the Palestinian Authority has stopped its “pay for slay” program (see Wikipedia article on the Palestinian “Martyr’s Fund”) which gives Palestinian prisoners in Israel (or Palestinians killed or injured while enacting terrorism money based on how many Jews they have killed or tried to kill (not a lot of people know about this).

Palestinian Authority (PA) Chairman Mahmoud Abbas issued an order to cancel laws and regulations related to paying financial allocations to the families of Palestinians linked with terrorist activity, known as “pay for slay,” on Monday, according to Palestinian Authority state media WAFA.

Additionally, the computerized cash assistance program, along with its database and financial allocations, will be transferred from the Ministry of Social Development to the Palestinian National Institution for Economic Empowerment, WAFA stated.

The amendments will allow all families previously benefiting from the former laws, regulations, and legislations to be subject to the same eligibility criteria as other families enrolled in social protection and welfare programs, according to WAFA.

The Palestinian Institution for Economic Empowerment will now assume full authority over all social protection and welfare programs in Palestine. It will be responsible for providing assistance to all Palestinian families in need, without discrimination, WAFA added.

Why are they eliminating this odious fund? Because Trump cut of all money to the Palestinian Authority, and Israel is withholding the pay-for-slay money from the prisoners. And, on top of that, there’s this:

This comes amid news that, on February, US courts will impose heavy fines – of about $200-300 million – on the Palestinian Authority – following lawsuits filed by families of terror victims. The PA is reportedly worried that this will lead to a financial crisis.

The Palestinian Authority arranged payment for families of dead Hamas terrorists amounting to a combined total of around $2.8 million, following the October 7 attacks, according to a report by the Palestinian Media Watch (PMW), a nongovernmental organization and media watchdog group.

With U.S. aid cut off, and fines in the offing, Abbas is in danger of losing his Presidency for life (that would be a good thing.) To try to avoid bankrupting the West Bank, Abbas seems to have decided that he can sacrifice the pay-for-slay program.

*From The Free Press‘s daily newsletter (yesterday) about the Super Bowl. You’ll want to click on some of the links, but I’ve also put two of the videos below (one is in a tweet).

The Super Bowl isn’t just a game, it’s a cultural barometer—and sometimes, a crystal ball. In 2016, Beyoncé danced on the Super Bowl stage to her new song “Formation,” flanked by backup dancers dressed like Black Panthers. Controversy ensued, foreshadowing the great war over woke that would dominate for years to come.

This year, another vibe shift. The NFL changed the message stenciled into the end zone from “End Racism” to “Choose Love.” Trump showed up—the first sitting president to do so—and his favorite patriotic walk-on song, “God Bless the USA,” was heard playing in the stadium. Kendrick Lamar’s halftime performance featured a nagging Uncle Sam character (played by Samuel L. Jackson) who told the rapper not to be “too ghetto,” but when backup dancers dressed in red, white, and blue formed the American flag, it felt more patriotic than political, even though his song “Alright” is perhaps best known as BLM’s unofficial anthem. And in another patriotic move, Kendrick performed “Not Like Us,” his Grammy Award–winning diss track against one of America’s new trade war enemies—Canadian rapper Drake.

Speaking of Canada, even the ads couldn’t escape the vibe shift. In the wake of Trump’s proposed, but currently delayed, 25 percent tariffs against Canadian goods, the province of Ontario ran an ad reminding Americans that Canucks are important trade partners and good neighbors, eh bud?

Speaking of “bud,” Bud Light launched a new ad to convince America they aren’t woke anymore. Still reeling from its disastrous 2023 campaign with transgender influencer Dylan Mulvaney, which spurred an effective conservative boycott, the beer’s new commercial featured Peyton Manning, Post Malone, and Shane Gillis—a comic who was infamously fired from Saturday Night Live in 2019 for affecting a Chinese accent on a podcast. (Read Anson Frericks’ great essay on the Bud Light saga.)

Bud Light wasn’t the only company with a subtle rebrand. After a backlash last year over their support for trans women participating in female sports, Nike launched a new ad putting female athletes front and center. The tagline: You can’t win, so win. Well, maybe they can’t win because they’re competing against biological males, Nike. Still, the ad is about female sports and features only female athletes, which is radical conservatism by Nike’s standards.

The Nike ad (note the FP’s comment) is among the tweets below, along with a counter-ad by women objecting to trans-identified males competing in women’s sports.  Here’s the Bud Light commercial:

Meanwhile in Dobrzyn, Hili and Szaron are in the kitchen, closely watching Andrzej:

Szaron: What is he doing? Hili: I don’t know, but it’s not what we are waiting for. In Polish: Szaron: Co on robi? Hili: Nie wiem, ale nie to, na co czekamy.

As part of their ongoing mission to push the boundaries of space exploration, NASA’s cutting-edge robotic hand is bringing us one step closer to a future where machines can grab objects just like humans. The machine which has been designed for dexterity and precision, isn’t just about gripping objects—it’s about revolutionising how astronauts and robots work together in space. With applications ranging from spacecraft maintenance to cleaning up space junk, this high-tech hand is paving the way for a new era of spacecraft operations.

Satellites have revolutionised modern life, bringing us global communication and navigation to weather forecasting and scientific discovery. However, as space becomes increasingly crowded, a growing threat grows above us—space debris. Thousands of decommissioned or unused satellites, spent rocket stages, and fragments from past collisions now orbit Earth at high speeds, posing serious risks to spacecraft and future missions. As space agencies and private companies launch more satellites than ever before, finding solutions to manage and mitigate space debris has become a critical challenge for the future of space exploration.

Space debris is a particular problem that NASA’s new Astrobee system is ideally placed to address. With over 36,000 pieces of debris larger than 10cm and over 100 million smaller than 1cm, all orbiting Earth at speeds in excess of up to 28,000 km per hour it’s a problem we must start to deal with.

Astrobee is a free-flying robotic system that has been initially designed to help astronauts on board the International Space Station (ISS.) The system is composed of three cube shaped robots that have been named Bumble, Honey and Queen! The system could navigate around the ISS without human intervention using their sensors to see. The system also comprises of an arm that allows it to grab onto handrails on board to stabilise itself and conserve energy.

The system, that was designed at the NASA’s Ames Research Centre has been on board the ISS since 2019 but it could go much further. It’s certainly been of great help around the ISS but deployed into orbit with a suitable propulsion system and power source, the sensor guided robotic arm could grab onto and manipulate pieces of debris. It could ultimately be used to collect debris like a space based road cleaner. 

Astrobee isn’t the only approach being taken to cleaning up the debris in space. The European Space Agency have also been experimenting with robotic arms and nets in their  ClearSpace-1 programme which aims to capture debris using robotic arms or nets and deorbit it safely. There is also talk of using harpoons to capture debris too but, and whilst I love the idea of harpoons around to grab debris it feels like it could be a dangerous option. 

Lasers are another option that has been considered as has ground based tethers, the use of solar sails and other de-orbit technology. Whichever technique works, it’s great to see space agencies around the World taking space debris and its clean up seriously. Hopefully if Astrobee can prove itself it too can join the ranks of growing janitors to our Solar System.
