dashundchen··on Microplastics in the human brain
I make at least trip one trip a week. Why would I need to go every day?

I may stop by a store again during the week for a smaller trip if there's something I really need, or pop to a corner store if I need to grab something like drinks for guests, but it's not out of my way.

It's really not a big deal. Bike panniers can hold a ton.

dashundchen··on Microplastics in the human brain
I do on a bike or walking weekly, it's not that crazy.

In a prewar US mid sized city, the density supports multiple grocery stores I can reach in about the same time as driving and finding parking.

EV/hybrids also have regenerative brakes so emit less brake dust. Between emissions, tires, and brakes I'd be curious to see how it balances out.

But really cycling and transit are the way to go to make cities more liveable. Personal cars take too much space in a city and ruin the built environment for everyone not in one.

dashundchen··on They Thought They Were Free: The Germans, 1933-45 (1955)
We all saw the Nazi salutes with our own eyes, the man and his ex girlfriend both follow and interact with avowed white supremacists and Nazis on his own platform.

The lie is coming from Musk and his cult of supporters.

dashundchen··on Trump slaps tariffs on Mexico, Canada and China
They've been telling us the plan.

Fascist Elon Musk was telling us before the election they were going to crash the economy and wreck the government. Project 2025 was freely available.

https://www.marketwatch.com/story/kaboom-elon-musk-predicts-...

They want to snap up assets, strip mine and privatize government services once theyre broken, and install the billionare oligarchcy as the permanent ring class.

Theyre speed running Russia's 1990s economic crash into oligarchy.

dashundchen··on Meta is killing off its AI-powered Instagram and Facebook profiles
Meta's platforms are already filled with AI slop content farms that drive clicks and engagement for them.

I have a FB account for marketplace, and unsubscribed from all my pages and friends. If I log in, my feed is a neverending stream of suggested rage bait, low quality AI photos, nonsensical LLM "tips" on gardening and housekeeping.

The posts seem to attract tens of thousands of reactions and comments from seemingly real people.

dashundchen··on Supreme Court rules ex-presidents have immunity for official acts
Why does the president deserve some fundamental immunity with a very high political bar to clear, compared to average citizen or politician?

Carving out some special protection strikes at the heart of the idea that everyone is equal in the eyes of the law.

dashundchen··on Gilead shot prevents all HIV cases in trial
Programs like George Bush's PEPFAR have made great strides in fighting HIV globally through treatment and prevention. Estimated at 25 millions lives saved in 20 years, mostly in Africa.

https://en.m.wikipedia.org/wiki/President%27s_Emergency_Plan...

Unfortunately it's become a target of the right wing culture warriors and certain groups are trying to gut it, after huge strides have been made in reducing global transmission of HIV.

dashundchen··on Alienating Tesla Buyers by the Cybertruck-Load
Musk's deranged "anti-woke" and racial obsessions[0], combined onto the huge quality problems I regularly see pop up online, plus the never ending "full self driving by the end of the year" sideshow all turned me off Tesla. A unserious CEO leading an unserious company, selling an expensive and potentially lethal machine. I don't want to drive a car whose safety features change weekly with whatever Musk tweets out.

Maybe a few years back before COVID I would have been a Tesla customer. Instead I opted for an EV from a traditional manufacturer. Great quality and drive, it suits me just fine, even if the software isn't the most advanced.

[0]Funny to me that the anti-woke reactionaries are way more obsessed with race and gender then almost any left wingers I have known. They build up these social media scarecrows of what is "woke" to rile themselves up.

dashundchen··on Biden's new student loan forgiveness erase up to $20k in interest for millions
As someone who paid off their student loans in full, I'm happy for those who are getting loan forgiveness.

Trump's 2017 tax bill gave away trillions mostly to rich business owners. Another trillion was dumped on them during COVID via PPP.

So if we can forgive a fraction of the debt for the working class that came of age when a degree was sold as a requirement for entry into the middle class, then great, all for it.

I know people who were required to get an MS in education to teach. The only option for certain education specialties in the region was a private school. Teaching is hardly a lucrative career, the public service they provide is necessary, forgive the debt via PSLF.

The government makes policy all the time that benefits certain groups, that's reality

dashundchen··on PFAS Used in Grease-Proofing Agents for Food Packaging No Longer Sold
Which brand? I know all bike chains come with factory grease but I don't know if I've ever seen it indicated what they are lubricated with.

Of course there are plenty of commercial bike lubes that come with Teflon aka PTFE mixed in.

Completely unnecessary, there's a movement to move towards simple paraffin or natural waxes in the cycling community. In fact, wax wears chain less via less contamination and is vastly more efficient than many of the teflon drip lubes.

dashundchen··on The Texas Triangle: A rising megaregion unlike all others (2021)
> So the government is in a position of "we'll give you X for this, but if you don't agree we'll just take it from you", which is a... non-Texan position for government to be in, to say the least.

Texas government doesn't seem to have that reservation when it comes to highway expansions within cities, that's for sure.

dashundchen··on Dealerships Rip You Off With The “Four-Square,” Here’s How To Beat It (2007)
> Find out what tax and title should be, assume a $500 "documenting fee" do a notional write up in advance, bring a calculator

A few states have capped or fixed document fees. In New York State, it's currently up to $175 for the dealer, plus any fees you owe to the state for title and registration (should match what the state charges for you to do it yourself).

Many states have no cap and it's no uncommon to find $500-$1000 doc fees. Check your state's law.

dashundchen··on Why "Freakonomics" failed to transform economics
I listened to a few episodes of this podcast, I don't think they are necessarily fair with each book they discuss. There are, however, many problems with Freakonomics drawing conclusions that aren't justified. They quite rightly point a few out.

I wouldn't say the hosts' ideology is "DEI", whatever you mean by that.

dashundchen··on 'Baby Bust': Why Fewer Young People Expect to Become Parents (2013)
I have a feeling you already know there's a conservative movement to roll back access to contraception (Burwell v. Hobby Lobby?), but if you needed any further proof, mainstream far-right conservative Clarence Thomas explicitly wrote in the Dobbs opinion:

"In future cases, we should reconsider all of this Court's substantive due process precedents, including Griswold, Lawrence, and Obergefell,” Thomas wrote in concurrence. “Because any substantive due process decision is 'demonstrably erroneous,' we have a duty to 'correct the error' established in those precedents"'

and many sibling posts have cover the current legislative initiatives to restrict birth control.

So yes, the far-right does want to roll back access to birth control, the right to marriage equality, the right to privacy between consenting adults. The American far-right wants a big brother government enforcing their personal morality on the whole country, right into our bedrooms and bathrooms.

dashundchen··on Welcome to the "neomedieval era": are states becoming obsolete?
Enough rewriting history that January 6th was some sort of peaceful protest.

No political support except coordination between the Trump administration and the convicted leaders, dozens of these them, charged with seditious conspiracy of both the Proud Boys and Oath Keepers, key planners behind the January 6th insurrection.

No political support except the march on the capitol beginning with Trump saying ""We fight like hell. And if you don't fight like hell, you're not going to have a country anymore," before telling his supporters to march to the capitol. The same crowd not standing down until Trump told them to "Go home, we love you".

No political support except some Republican members of Congress leading riot participants through the capitol in the days before the event.

An event that was literally designed in adanvce to pressure Congress and the Vice President with the threat of violence (gallows and a crowd chanting "Hang Mike Pence") into rejecting legitimate election results and accepting slates of false electors. A crowd running through the Capitol chanting "where are you Nancy?" - echoed in an attack on her husband Paul Pelosi not long after.

An event that was proceeded by pipe bombs planted at the GOP and Democratic headquarters.

An event that involved the beating of Capitol police officers to force their way into the inner chambers of Congress.

And you're lying about insurrectionist Ashlii Babbit. She was not shot in the back, she was forcing herself into a shattered window, into a hallway where Congress was evacuating, along with other rioters.

Tell me, what was the end game of the rioters there? What do you think would have happened had they managed to get into the chamber while Congress was still present?

dashundchen··on Plastic bag bans work
Yes, which is why they'd have a interest in publishing studies that make bag bans look useless or counterproductive, because they want to persuade people not to pass or to repeal bans.
dashundchen··on EV drivers discover fundamental flaw in battery tech as -30F temps hit the US
I love winter. I love summer too but I don't think I would appreciate summer without a cold winter.

Fresh snow makes gives my city a clean soft look, hiding the dormant brown of fall. It quiets and slows the cars. People out walking become friendlier. Snow's reflectiveness can make the darker days of the year so bright. You can walk anywhere on frozen ground and roll around on snow without getting muddy. You can ski, sled, or just walk and enjoy it. A breath of cold air wakes you up instantly.

Unfortunately my region, the Great Lakes, has been rapidly warming and trending towards rainy near-freezing winters instead of snow. But I do appreciate every snow we get. It probably helps I live in a city and don't need to drive.

dashundchen··on X Bans and Then Unbans Journalists and Podcasters in Latest Free Speech Massacre
They're pointing out Musk's hypocrisy after repeatedly claiming himself to be a "free speech absolutionist". If someone hurts his feelings or calls out his BS he bans or blocks them. Very thin skinned and sensitive, desperate for attention and likes. I'm not even on Twitter and I've heard of this.
dashundchen··on Study Finds Microplastics in Nearly 90% of Proteins Sampled
If you look at the actual data, tofu had the third lowest concentration of microplastic particles per gram (0.03, vs 0.02 for pork loin chop and 0.01 for whole chicken breast).

The press release does a disservice to the study by referring to the highly processed group as a whole and not excluding tofu. For reference, the breaded shrimp and fish sticks were measured to have 1.2 and 0.26 particles per gram.

Table 3.7 https://www.sciencedirect.com/science/article/pii/S026974912...

Regardless if a processed food like tofu has minimal plastic concentration, I would assume minimally processed whole plant food like beans and nuts would also have low microplastic exposure. The study found little total plastic from packaging, their evidence pointed towards the processing.

dashundchen··on US unemployment has been under 4% for the longest streak since the Vietnam War
In 2023, most workers had wage growth stronger than inflation, which is also true for the post pandemic recovery.

"The data reveal that as of late 2023, most workers are earning more, in inflation-adjusted terms, than they were one year prior, and the fraction of workers receiving real wage increases is about the same as it was in the years before the pandemic. The data also suggest that most individual workers are earning more today than they were before the pandemic; every prime-age worker cohort has higher inflation-adjusted median wages than before the pandemic.

dashundchen··on LA Sheriff Still Has 429 Ford Crown Vics in Service Because It Stockpiled Them
Huh? Seems like a unfounded assertion that there was some prevelant left-wing mockery of American sedans at all, especially one that American auto executives would have responded. These companies care about one thing, what sells and makes them money.

What's more likely is these were cars were boats built on ancient body-on-frame platforms into 1990's, which were killed in sales by Japanese sedans perceived as more efficient reliable (Honda Civic, Accord or Toyota Camry/Corolla). Not to mention the body-on-frame sedans were not up to increasingly stringent crash tests, which required crumple zones. The B-Body platform Impala you refer to is a variant of a platform that was introduced in the 1920s!

Look at how much US market share GM bled in the 80s going into the 90s. The products were not competitive.

The big three American manufacturers were viewed as unable to compete in the sedan space which is why they pivoted to the truck and SUV market, which continues through today (not coincidentally trucks and SUV benefit from CAFE standard loopholes along with the protectionist chicken tax, a 25% import tax on light trucks [0])

dashundchen··on Purple Llama: Towards open trust and safety in generative AI
The safety here is not just "don't mention potentially controversial topics".

The safety here can also be LLMs working within acceptable bounds for the usecase.

Let's say you had a healthcare LLM that can help a patient navigate a healthcare facility, provide patient education, and help patients perform routine administrative tasks at a hospital.

You wouldn't want the patient to start asking the bot for prescription advice and the bot to come back with recommending dosages change, or recommend a OTC drug with adverse reactions to their existing prescriptions, without a provider reviewing that.

We know that currently many LLMs can be prompted to return nonsense very authoritatively, or can return back what the user wants it to say. There's many settings where that is an actual safety issue.

dashundchen··on Truth Social reports $73M net loss since launch
I still want to know the full extent of Jared Kushner's work in Saudi Arabia, acting as a senior policy advisor hired by Trump.

We know about the $100 billion dollar Saudi arms deal that Kushner inserted himself in after the murder of Jamal Khashoggi. We know he personally backed Saudi Arabi in their conflict with Qatar. We know Kushner failed to disclose he owed around a billion dollars on failed investments in real estate.

Now after Kushner leaves government, MBS overrode his advisors to hand over $2 billion of state investment to Kushner's newly established fund.

What happened there?

dashundchen··on Windows CE's final day
Moving to the closed app store ecosystem, and breaking app compatibility twice with the move from 6 -> 7 -> 8 definitely killed all developer momentum for their platform.

But the Metro UI on Window Phone 7 and the Zune HD was handsdown the best and smoothest smartphone UI I've used yet. It's a shame it was killed with the Windows 8 blunder.

The Nokia Lumia phones had some amazing hardware for the era too. Head to head with Apple and leagues better than the chintzy Android phones of the era.

Neither Apple nor Google have come close to replicating something as intuitive.

dashundchen··on Weight-based motor vehicle tax
Take a look at:

Hyundai Kona EV

Kia Niro EV

These two have been around for a few years and are on the second gen. You can get a low mileage first gen for under $25k, which means you may get an additional $4k federal tax credit. One issue to watch out for is the cover for the gear reduction unit should be replaced with a magnetic one and cleaned periodically, to avoid motor damage.

Volvo EX30 - out next year, going to be under $35k

There's also the generation of used compliance EVs like the VW eGolf and Hyundai Ioniq hatch.

All are sold as SUVs but they're really compact hatchbacks with some SUV like styling.

dashundchen··on Doctors on TikTok
> However, I think there is a place for surgery to be shown to the general public, but from an educational perspective for both healthcare professionals that are learning, but also for people to know what happens to their bodies when they have surgery.

Absolutely. Obviously not for every patient as some are more squeamish than others.

I recently underwent a surgical procedure. It was great to be able to find several recorded procedures on YouTube. The videos were recorded in an academic context rather than sensational clickbait, it definitely made going into the procedure easier.

dashundchen··on In California, Car Buyers Are Choosing Electric over Gasoline in Record Numbers
1500 mi/yr is nothing, definitely not worth the cost of a new car! Consider many modern cars and especially EVs are expected to last well over 200k mi. The car will rust away before you hit 30k mi.

It's impressive to be voluntarily low car in Ohio considering the sorry state of transit and bike infrastructure in Ohio's cities. Pretty difficult with the exception of Cleveland's core.

If carshare is unavailable and you really want an EV, I would look at the last generation EVs - used Kia Niro, Chevy Bolt, Hyundai Kona, Hyundai Ioniq (old hatchback, not the 5 or 6), VW eGolf, or a Nissan Leaf if you have a spot to charge.

Many of the older models will be under $25,000 used and therefore eligible for an income restricted $4,000 federal tax credit.

Took a look through auto trader and there's quite a few used EVs in Ohio that would near $10k with the tax credit.

Curious what your primary transportation is - bike or ebike?

dashundchen··on Ocean Heat Record Broken
I'd love to hear what the mainstream right-wing plan for addressing climate change is then.

Because right now it appears to be "deny it's happening, let's continue enriching fossil fuel shareholders" [0]. And there is increasingly large human cost to doing that too.

dashundchen··on Ocean Heat Record Broken
That's ignoring all the issues American environmentalists identified and were proven right about since the dawn of the movement.

DDT thinning bird eggs and causing near extinction of many species? Banning DDT resulted in recovery.

Companies dumping sewage, PCBs and industrial waste into our water, killing entire ecosystems? While not perfect, the Great Lakes and many rivers are worlds apart from where they were 50 years ago thanks to the EPA and Clean Water Act.

Same situation for the Clean Air Act.

Same for the Endangered Species Act.

Same situation for banning lead from paint and automotive gasoline.

Same situation for the ozone layer and the Montreal Protocol.

These movements were not unopposed. In most of those fights, business and conservative (in the traditional sense of the word) groups fought against the regulation needed to address the problem. Hell, the current GOP platform for 2024 is to completely gut the EPA's authority within the first year.

https://www.politico.com/news/2023/07/28/far-right-climate-p...

Climate change is much more complex than any of the mentioned issues and will take much more global cooperation. Crazy to somehow blame this on environmentalists just because the effects are larger scale and slower-changing.
