30 years ago today, Phrack 49 published Aleph One’s “Smashing the Stack for Fun and Profit”. A legendary paper that inspired generations of hackers and helped shape modern exploit development. Still an essential reading. phrack.org/issues/49/smashin… Phrack 73 is coming soon!

Two former female US navy admirals fired by ex Fox News host and now US Secretary of Defence Pete Hegseth have both won congressional seats in the US . Now they may get the opportunity to impeach him. Karma can be wonderful, especially for manic misogynists!

This home invader raped a woman at gunpoint around 10:30 Friday morning. Then the victim waited hours for Chicago police to respond because there weren’t any cops to handle the assignment. NINE 911 calls were made. cwbchicago.com/2026/11/woman…

Wow. Nolan Finley, editorial editor of the Detroit News and a solid conservative voice on its pages for decades, says loud and clear what many Republicans are quietly thinking: Republicans shouldn't block Democrats from impeaching Trump | Finley detroitnews.com/story/opinio…

Mathematicians are whining about how their job is reduced to understanding proofs spat out by computers. Suck it up. I spent the first half of my career debugging. Now it's your turn.

Espionage is world’s second oldest profession. No surprise, such a recruitment op. A perfectly placed agent. So biggest question, is why lack of USG action? Where r the responsible CI pros within govt on this? … @BillEvanina (my go to China CI expert), thoughts? Finally- assume incoming HPSCI and SSCI led Democratic chairs will take additional oversight steps?

Kraken co-CEO Arjun Sethi says self-custody is a ticking time bomb, while quantum is a migration problem, not an extinction event "A meaningful share of all Bitcoin is also probably gone forever. I would say that's a little broken in itself. Lost seeds, dead hard drives. I have had those problems myself personally." "Self-custody that fails on inheritances and safety. I think that's like a ticking time bomb." "Then we're talking about quantum. I think this is the part where people are worried about, which is it threatens signatures, not hashing. It's like an important dichotomy." "The coins at risk are the ones whose public keys are already onchain, like old outputs, reused addresses, et cetera, et cetera. Even post-quantum signature standards exist." "The hard part is really going to be about how do you coordinate every wallet and custodian to migrate. That's a migration problem. That is not an extinction event." "I listen to a lot of podcasts and sometimes I'm like, that person has no idea how any of this stuff works."

“Twitter isn’t real life” has always been an important maxim to keep in mind lest you overfit your politics (see: cancellations). That’s especially true now that this site has effectively no anti-bot control, sells blue checkmarks and directly monetizes outrage.
Exactly. Certain folks had the idea that if they could get thousands of likes for people who said rightist shit, that somehow the American electorate would become rightist too. It doesn't work like that.

Had drinks with the finance manager at a Ferrari dealership in Miami who has sold 400+ cars to guys worth $20M+ Asked him how the richest buyers actually pay for a $380,000 car He laughed and said "they put the $60,000 deposit on 0% business cards under their LLC and their cash never leaves Treasuries" Thought he was bullshitting me until he walked me through the credit packets sitting on his desk Everyone assumes a guy making $2M a year wires cash out of his personal checking account or takes out a personal auto loan When the dealership pulls the file on a high-net-worth business owner, they see the exact same setup almost every time: 1. His personal credit report under his Social Security number looks untouched: a 775 FICO score, two personal cards with a $300 balance, under 2% usage 2. Under his LLC's federal tax ID (EIN), he holds 5 or 6 business credit cards across Chase Ink, Amex Blue Business Plus, US Bank Triple Cash, Wells Fargo Signify, and PNC totaling $220,000 to $300,000 at 0% interest for 12 to 18 months 3. He swipes $60,000 for the car deposit plus all his company's equipment, ads, inventory, and tax bills on those 0% business cards while his actual cash sits in Treasury bills paying 4.5% He gets three wins on the exact same swipe: - His $250,000 in cash earns $11,250 a year in risk-free yield for 12 to 18 months before he pays the cards off - Running $250,000 through Chase and Amex prints 400,000+ tax-free points that cover his flights and hotels - Zero dollars of that $250,000 balance ever show up on his personal Experian, Equifax, or TransUnion report because those business cards only report to commercial bureaus Compare that to what a Miami dentist making $400,000 a year with a 755 credit score did the same afternoon He financed a $75,000 BMW M3 on his personal credit file at 7.9% interest and put $15,000 of office equipment on his personal Amex. Thirty days later his personal score dropped 58 points and his mortgage lender bumped the rate on his house refi by half a point Both guys walked in with a 750+ score at the exact same banks. One guy used his personal credit report and got punished. The other guy put $250,000 on his LLC at 0% interest and kept a spotless 775 personal score You don't need $20 million or a Ferrari to run that setup. A 700+ personal credit score and a clean LLC unlocks the exact same $150,000 to $250,000 0% stack for business equipment, inventory, real estate, or vehicles The catch is that if you apply for those 5 business cards in random order, Chase 5/24 and bank velocity filters see back-to-back hard inquiries on the same credit bureau in your state and cap your second and third cards at $8,000 instead of $50,000 (If you have a 700+ credit score and want my team to build your 150K-250K 0% funding stack, book a call using the link in my bio)

In addition to the team’s No. 6 opposing solo pilot, who flew during the 2026 season, the Blue Angels also quietly removed their Public Affairs Officer (PAO), Capt. Danielle Cribb, last month. Updated story: theaviationist.com/2026/11/0…

He was 80 years old and just picking up his amps from the repair shop. Bob Wood plugged in his 1968 Epiphone Riviera to test them at a Nashville shop in 2014, played "Bésame Mucho," and a tech grabbed a camera. Back in 1968, he'd turned down Sam Phillips' offer to play sessions at Sun Records so he could raise his nine kids. Bob passed in 2022 at 88. He played to the end.

Trump thinks he can sign an executive order that will prevent any future president from touching his precious, and hideous Oval Office. He really wants so desperately to be king.
Trump: We have something that’s of great interest to a lot of people: the Oval Office and the Cabinet Room. And I’m going to be signing a document which will make them into a landmark for the ages. It won’t be able to be taken down, destroyed, touched, or anything else. It’s a federal landmark. And when completed, and when we get the documentation fully done, legally binding, it’ll make it impossible for anybody ever to destroy this incredible space.
