I'm pretty happy with the top side Samtec ARF6 launch simulations now.
S11:
* Red: No cutout, -12 dB at 10 GHz, -7 at 20 GHz, -4.8 at 30 GHz
* Blue: Rectangular ground cutout the size of the pad, -22.5 at 10 GHz, -16.4 at 20 GHz, -11.7 at 30 GHz
* Green: 30um larger than the pad on all sides (1.06 x 0.41 mm), -30.5 at 10 GHz, -22 at 20, -15 at 30.
With the oversized cutout it's more than good enough for QSGMII and 25Gbase-R.
TDR:
* Red: No cutou…

Post shared with me by @… about twenty minutes ago when I last heard from her to know she’s alive.
(israel’s occupation forces have surrounded her neighbourhood with tanks and are firing on houses and tents. The israeli genocide of the Palestinian people is being live streamed by its victims.)

Screenshot of social media post by Mohammed Haniya: Dozens of distress calls were made tonight from the Al-Sabra neighborhood in central Gaza City, following heavy artillery and air strikes that left dead and wounded, but ambulances have not yet been allowed to reach them. Entire families spent the night in indescribable terror, without electricity, without water, without safety. Some slept amidst the blood, while others remained beside the bodies of their loved ones until dawn, waiting for a …

Radioactive Cesium gives the shrimp an extra tangy-ness, and it can give you a warm feeling inside for the rest of your life. 🦐🍤😋🤤🥵🤯💀
But we don’t need no stinkin’ food inspectors, do we doge/maga; thank god for musk/45.

Yeah, this is not surprising…
“Airlines and Trump Administration Backpedal on Protections for Travelers With Wheelchairs”
nytimes.com/2025/06/20/travel/
Archive: …

The Transportation Department, meanwhile, has repeatedly delayed enforcing compliance with the rule, and has asked the court to pause the litigation while it reviews the rule to “ensure that it is consistent with the law,” according to a court filing. A department spokeswoman said its review would also cover administration policies and issues raised by the airlines’ lawsuit.

Airlines Challenge Protections For Travelers With Wheelchairs
A landmark rule to expand the rights of disabled air travelers has been hamstrung by a lawsuit from major airlines and delayed enforcement by the Transportation Department.

Here’s the key point: Trump’s corruption of justice isn’t just individual; it’s categorical. We have grown accustomed to him rewarding his loyalists and punishing his critics. That he fired the prosecutors who worked on his federal criminal cases while pardoning the Jan. 6 rioters represents a textbook case of individual favoritism.
The Trump administration’s abuse of the civil rights division is something else entirely. It had already initiated a “litigation freeze” on filing new civil rights cases, and it had indicated that it was even going to reconsider previous settlements and consent decrees intended to address police misconduct.
...
Civil rights laws are designed in part to protect innocent citizens — including, of course, innocent citizens from minority communities — from unjust government officials. Here, the legal world is turned upside down. The Justice Department is using its civil rights division to protect an unjust government official who violated the civil rights of an innocent individual.

An MIT report says 95% of GenAI pilots at companies have little to no financial impact, mainly due to a "learning gap" for both the tools and the companies (Sheryl Estrada/Fortune)

MIT report: 95% of generative AI pilots at companies are failing
There’s a stark difference in success rates between companies that purchase AI tools from vendors and those that build them internally.

It all fits. Suppose you’re corporate leadership. You’re laying people off / refusing to hire because you have no clue what things will look like even 1 or 2 years in the future, and you are •terrified•.
Meanwhile, your investors, your gullible trend-chasing investors, are already mentally dividing companies into “pre-AI” and “post-AI.” And not only do you have no idea how to be “post-AI,” but you have no idea whether you’ll be solvent next year. What do you tell them?!??
Obviously you tell them you’re not hiring because you’re having such incredible success with AI! Maybe even you’re going to lay off all the senior people! They’ll love that!
Now you’re not failing and flailing — you’re leading the march into the future! Yay!
