  2. Convincing my wife the 3D printer was worth it (Part 2) #3dprinting #3dprinted #diy

    > Why does a $1,000 stroller not have a cup holder??? I designed a custom 3D-printed solution to fit a massive Owala water bottle (and my McDonald's Diet Coke)...

    FINALLY, someone put a 3D Printer to good use and solve a real world problem instead of just producing more plastic waste. 😃

  3. Just a couple of hours left before our hands-on workshop. I created this slide to better explain how we can zero-proof the signature of a committed public key to allow "holder binding" with "BBS" signatures.

    I left out a lot of details, but it still looks overloaded :)

  4. MOHSEN K. MAHDAWI
    arrived at the U.S. Citizenship and Immigration Services office in Colchester, Vermont, on Monday.
    A Palestinian student at Columbia University, he hoped that, after 10 years in the U.S., he would pass the test to become a naturalized citizen. 
    Instead, agents from U.S. Immigration and Customs Enforcement arrested him and began the process to deport him to the occupied West Bank.
    Mahdawi, a leader of the campus protest movement against Israel’s war on Gaza, became yet another #green #card #holder arrested and facing removal.
    “Mohsen Mahdawi was unlawfully detained today for no reason other than his Palestinian identity,”
    Mahdawi’s attorney Luna Droubi said in a statement to The Intercept.
    “He came to this country hoping to be free to speak out about the atrocities he has witnessed, only to be punished for such speech"

  5. CW: Compliant Mechanism Print-In-Place Car Phone Holder That Prints Well On The Worst 3d Printers (Easy Print)
    Single part, ready to use the moment you take it off the print bed. Simple, visually balanced and well thought out phone holder from an independent designer - me :) . Smooth, satisfying compliant mechanism that holds the phone firmly. In a mesmerizing move, the holder opens up a space for a USB cable below the phone, once you insert it into the frame. How many times have you downloaded something marked as "print-in-place" only to discover the moving parts come out fused together, too tight or clunky? Wet filament ruined the print with stringing? This time there's no need to worry. This object will print successfully even on a machine from a different age on a terrible quality filament due to the compliant mechanism design. The elements don't have to roll, turn or click, they just bend. The clips to insert it in the AC vent are an integral part of the holder, see the video! There's a version with and without a cut-out to accommodate for a ring on the back of your phone case. It can fit phones up to 8cm wide (3.15in) and 1.2cm thick (0.5in) without model resizing. Remember that springs also scale when resizing, thicker springs will have more tension. Print it with PETG for the clips to bend back as intended, without breaking.

  7. Flag down on the play, B&H Photo-Video! Was repeatedly assured in-store that buying items & having them shipped would not incur any charges (I bought $200 of stuff!). So when it shipped & I saw a shipping charge, I called right away. Not like them, they're usually more honest.

  8. On the U.S. Supreme Court
    —Chief Justice John Roberts and his Republican majority have spent decades systematically dismantling the guardrails of American democracy.

    Itself the product of unprecedented norm-breaking
    —encouraged by a fifty-year special interest campaign designed to weaponize the judicial branch
    —it is the Roberts majority that has hastened our endemic institutional collapse.

    We can draw a straight line, for example,
    from the Roberts Court’s 2010 #Citizens #United decision, which invalidated Congress’s bipartisan campaign finance limits on the farcical premise that independent expenditures could not be corrupting,
    to the imminent shadow presidency of erratic mega-billionaire Elon Musk, Trump’s biggest outside spender. 

    Citizens United set the stage for the proliferation of political nonprofits and the establishment of #Super #PACs,
    giving oligarchs like Musk a megaphone loud enough to drown out ordinary voters.

    The decision turbocharged Trump’s rise, allowing his allies to flood the airwaves with disinformation and propaganda,
    meanwhile trapping Democrats in a system of corporate-funded campaigns that has eroded their ability to represent the working class.

    Three years later, in #Shelby #County v.#Holder, John Roberts completed his career-long vision quest to dismantle the Voting Rights Act,
    invalidating its preclearance requirement for states with a history of racial discrimination.

    Erasing the national consensus first achieved in the bloody crucible of the Civil Rights Era
    and repeatedly reaffirmed by near-unanimous bipartisan Congresses, Roberts deemed racial discrimination a relic of ancient history,
    declaring that “nearly 50 years later, things have changed dramatically.”

    A flood of Republican state voter suppression laws followed, funded, and orchestrated by the same interests to which Roberts owed his majority.

    “Throwing out preclearance when it has worked and is continuing to work to stop discriminatory changes is like throwing away your umbrella in a rainstorm because you are not getting wet,”
    Justice Ruth Bader Ginsburg warned in her searing Shelby County dissent.

    But soaking us was the whole point.
    The downpour continues.

    Final results for the 2024 House elections were tallied recently, and Republicans will owe a razor-thin 220-215 majority to the three seats the GOP flipped thanks to the North Carolina legislature’s brazenly partisan gerrymander,
    a move blessed by the Supreme Court’s Republican justices’ 2018 decision in #Rucho v. #Common #Cause.

    In that case, the Roberts Court
    —so power-hungry that leading legal scholars have dubbed it the “Imperial Court”
    —conveniently found that #partisan #gerrymandering,
    -- a practice dominated by norms-be-damned Republican state legislatures,
    -- presented a “political question” that was outside their purview to resolve.

  9. Co jak co, ale skład #ROWRybnik na 2025 wygląda tragicznie… #Drabik, #Holder Ch. i #Czugunow. Pierwszy słaba psycha, drugi to już dawno minął się ze szczytem kariery, a trzeci to zwykły mięczak. Nie wróżę sukcesów. Aczkolwiek myślę, że będzie Lublin i Toruń, potem będzie próbował równać Wrocław, a dalej długo długo noc i walka o utrzymanie pomiędzy wszystkimi pozostałymi.

  10. New LED holder design, now with connector so you can change the LED without having to use a soldering iron 😎.

    I did it to be able to mount the Bridgelux V8s I'm using, with 3mm polycarbonate scraps I had around here.

    The future plan is to migrate to the Bridgelux V6s, which have more standard measurements and can be used with TE's Z35 holders.

  11. I now have a stand/holder designed for this case.

    thingiverse.com/thing:6755438

    For this I used CadQuery (rather than Python on top of OpenSCAD). It's my first project with CadQuery; there are things I quite like about it, and other things I'm finding klunky, which probably means I'm using it wrong for those things. I expect it will get better as I get more comfortable with it.

  12. Some useful inequalities:

    1. Cauchy–Schwarz inequality

    \[\displaystyle\sum_{k=1}^na_kb_k\leq\sqrt{\sum_{k=1}^na_k^2}\sqrt{\sum_{k=1}^nb_k^2}\]

    2. Hölder's inequality

    \[\displaystyle\sum_{k=1}^n\left|a_kb_k\right|\leq\left(\sum_{k=1}^n|a_k|^p\right)^{1/p}\left(\sum_{k=1}^n|b_k|^q\right)^{1/q}\]

    3. Minkowski's inequality

    \[\displaystyle\left(\sum_{k=1}^n\left|a_k+b_k\right|^p\right)^{1/p}\leq\left(\sum_{k=1}^n|a_k|^p\right)^{1/p}+\left(\sum_{k=1}^n|b_k|^p\right)^{1/p}\]

    4. Hardy's inequality

    \[\displaystyle\sum_{k=1}^\infty\left(\dfrac{a_1+a_2+\cdots+a_k}{k}\right)^p\leq\left(\dfrac{p}{p-1}\right)^p\sum_{k=1}^\infty a_k^p\]
