Rooting around in my brief foray on SoundCloud from years ago. Not a total embarrassment 😁 Feeling the urge to pick that guitar up again now that my son is off to college as a jazz major 😎 on.soundcloud.com/oPrlzuPtse7a...

Timeboxes are just as effective enabling constraints as WIP limits and SLAs when it comes to stabilizing flow. They just rely on a different aspect of Little’s Law to do this. open.substack.com/pub/thepolar...

𝙒𝙝𝙮 𝙙𝙤 𝙒𝙄𝙋 𝙡𝙞𝙢𝙞𝙩𝙨 𝙖𝙣𝙙 𝙍𝙚𝙨𝙥𝙤𝙣𝙨𝙚 𝙏𝙞𝙢𝙚 𝙎𝙇𝘼𝙨 𝙬𝙤𝙧𝙠? We know from 20+ years of industry experience that these techniques produce stable processes, but what does that mean? In the next two posts in our series on Little's Law we show you. open.substack.com/pub/thepolar...

What if I told you the reason you might believe that Littles’s Law doesn’t apply to processes in complex adaptive systems is: 1. Your concept of “Little’s Law” is too narrow. 2. You are measuring the quantities in Little’s Law incorrectly. open.substack.com/pub/thepolar...

We’re up against a terrifyingly corrupt president abetted by a deeply compromised Supreme Court. It’s going to take new tools and different applications of the old tools to confront the threat we face. No shame in that.

They say you can’t apply Little’s Law in Complex Adaptive Systems. But they’re wrong.

Wait isn’t this the war Grandpa Don dodged?

Great work by @lawrencehurley.bsky.social here: www.nbcnews.com/politics/sup...

I renewed my passport online and it took 2 weeks to get my new book at home. No expedites, just regular process. Very smooth - just fill out a form and upload a photo taken from your camera. Looks like some Biden era programs are still running on autopilot. Hope DOGE doesn’t notice 😅

The irony here is that she seems to genuinely expect that readers will be surprised that a “proud“ conservative supports a govt program that directly benefits them. Her earnest naïveté is only surpassed by her cluelessness. www.nytimes.com/2025/08/21/o...

A real life American Hero... not hiding behind a mask. I bet soon we will know his name. We salute you brother for your civil courage and the eloquence.

Takes a lot of chutzpah to make a $290 million political donation, assume a powerful position in government, use that power to fire tens of thousands of people and do immeasurable harm to American state capacity, and expect not to have to answer for it afterwards.

Measles outbreaks are back. Grocery and gas prices are up. Bird flu is spreading. All our allies hate us. Air travel is getting unsafe. The stock market is tanking. The government is about to shut down. And he’s only been President for six weeks. This is just the beginning.

Donald Trump has disgraced the United States of America in countless ways since he first entered political life ten years ago. But he had never disgraced the nation as badly as he did today. He has brought shame on this country to an extent I had never thought possible. And he has only just begun.

Volodymyr Zelensky's Oval Office visit ended early when Donald Trump and JD Vance began angrily yelling at him. Here's why women like Kamala Harris and Hillary Clinton are too emotional to be president.

Gregg is a former Marine and Forest Service ranger. He's saved the lives of hikers dangling off a cliff or going through cardiac arrest, and he's bravely fought forest fires to save small rural towns. 100% of his salary is paid by WA state. Elon fired him. Share his story.

“Build your own fucking pedigree”! Indeed. The amount of time people waste mimicking what the SV companies do instead of figuring their own unique competitive advantage in their own market is astounding! But we also have an entire industry of “thought leaders” who encourage this. So 🤷

Wow, that was fast. Irving Energy, company that provides propane/fuel oil customers in New England, says it will pass on the full 10% tariff cost to all their customers immediately (reposting with fixed figure - meant to say 10%, not 30%)

Here's the speech if you haven't heard it. 13 minutes of your time. Share it with your American friends and neighbours, because they won't see it otherwise. Circulate it in Mexico and Denmark, France and the UK, Panama and Germany, Poland and Estonia, and especially -- especially -- Ukraine.

I can report some progress on the Racoon problem The latest version still can’t handle no raccoons and is less creative about solutions, but at least it is aware that it is screwing up and automatically retries three times before giving up. Progress..

What does a coffee shop have to do with value streams in complex adaptive value networks? A lot.. it turns out. www.polaris-flow-dispatch.com/p/value-exch...

Elections have consequences and this is one that personally terrifies me. www.science.org/content/arti...

Here I was thinking Apple Intelligence would finally make Siri usable.. but noooo..

Rest in Peace, Ella Jenkins.

The Bluesky A.I. data fiasco is a good teaching moment to shine light on how billion-dollar tech companies are scraping as much of the Internet as possible — social media, videos, trillions of words, billions of images — at industrial scale, with no real oversight, transparency or opt-out.

Don’t know what you’ve got till it’s gone..

The thing is..your customers and users don’t give any thought to what developers are working on right now. Keeping it that way is what “developer productivity” should be all about. Not whatever BS It is that we do in the name of productivity.

Is agentic AI going to create a modern incarnation of the BPO industry in which, instead of human, AI agents will be serving ? A new global BPO market ready to be rebooted ?

Damn and now Drake is going to have to pay a 25 percent tariff on that beef?

Matrimonial bombing… Or, a test for irony-deficiency..

But there is also the uncomfortable reality that tapping into populism is a frequent strategy for oligarchs seeking to consolidate power authoritarian regimes aiming to suppress dissent and corporate efforts to drive profits by appealing to simplified narratives and broad emotional appeal. 6/n

Exceptional variation was noticed in the flow of value on major social media (value) networks between mid October and early November 2024. Since this is a complex system involving many human actors, a root cause may never be determined…. www.polaris-flow-dispatch.com/p/value-netw...

If I order a pizza from Uber Eats and the delivery guy brings me BBQ from Stans, did any value flow? No. This is a failed value exchange. Happens a lot in software When value exchanges succeed consistently they create value streams. www.polaris-flow-dispatch.com/p/value-netw...
