So we had to develop technologies like this to barely manage control over limited areas in Iraq's few urban centers. Only ~8 in 100 Iraqi adults owns a personal vehicle. That rate is > 1 car/adult in America yet I have never seen any doctrine paper or work of fiction address this

We've seen and struggled in civil conflicts with instant, local, universal, distributed communications (cell phone era, basically every conflict since 2000). We've seen and struggled in conflicts with instant, global, universal distributed communications (everything since 2011).

The world's most overfunded military and glow in the dark agencies struggle and largely fail to contain conflicts where fhe vast, vast majority of people are locked into a ~5mi radius of their home.

How can they possibly contain a conflict in a nation with universal car ownership and the most developed road network in the world? The average car can travel over 400 miles on one tank of gas, how can you contain the potential of that kind of mobility?

I think that's partially why the system was so freaked out by 1/6. Yes, most of it is histrionics but you don't decide to indefinitely turn your capital into the Baghdad Green Zone with fortifications and 25k troops over histrionics alone.

Have you gotten tired of mechanical keyboards with all their physical feedback?

Have you considered... A completely flat keyboard?

It's very flat

my favorite part is that since all buttons are the same shape and size, the spacebar is just 8 space buttons in a row

So why is it flat? Just because they hate good keyboards? Nope! it's for a reason...

Surprise! the plastic cover can be lifted up. The keyboard layout is on a piece of paper.

And it comes with a blank one so you can make your own.

⚡️🧠Impact = Environment x Skill

A framework for making big career decisions by @iambangaly (Reforge Partner, Former Instacart, Instagram)

Full post -> https://t.co/dU0l7e0BWR

🧵 Thread...

1/ Career decisions about your next role/opp are the most impactful decisions you might make in your career. As an operator, all of your eggs are in one basket at a time, and we get a limited number of swings at the plate. So getting good at these decisions is important...

2/ At FB, Bangaly managed Rotational PM's. At the end of a rotation, he'd have the same convo: How are you going to choose your next rotation/role?

As a result, Bangaly got a lot of reps guiding this type of decision and created a framework to help with it...

3/ The framework is Impact = Skills x Environment

The goal is not to try and boil this type of decision down to a spreadsheet of inputs that spits out the answer, but rather it helps with 4 things...

4/ It can help with:

- Identify individual variables that are inputs into the decision.
- Evaluate each individual variable in a structured way.
- Understand the relationship between each variable.
- Narrow the decision down to the most important variable

For people curious about the Roam API and confused by the syntax, or interested in why Conor went with Datomic/Datascript and not a traditional database, this older talk by Roam developer @mark_bastian is a great overview.

He gives great examples using Spiderman of how even modeling something fairly trivial in SQL is much more complex than in Datomic. But the real kicker is when you're trying to interrogate the data to find recursive relationships.

Right now the Roam data model (at least that's exposed to developers) is just about pages, blocks, and children with tags. Already you can see how finding the page containing a block with a certain tag etc is useful.https://t.co/jWJnuKu1RG

But imagine when attribute relationships are fully represented

You should be able to model the entire Spiderman story in Roam.
Page title: Peter Parker
Child of:: [[Richard Parker]] [[Mary Parker]]
Aliases:: [[Spidey]]

etc, and do these kind of queries.

Incremental rebuild was a feature of the C# compiler which was meant to increase the throughput after an initial build. It worked on the principle that changes in between builds are localized, and that the information gathered by the compiler from previous builds wouldn't be

entirely invalidated; specifically, some of the information and, indeed, the assembly itself could be updated in an incremental fashion resulting in faster builds.

Both the VS 2002 and VS 2003 compilers exposed this option through the /incr switch on the command line, and the ‘Incremental Rebuild’ option in the Advanced tab of Project Properties. In 2002 incremental rebuild was enabled by default for all project types.

After we shipped 2002 we noticed that we started to get a large number of bugs (internal compiler errors - ICEs – the worst kind) which were a direct result of the incremental rebuild feature.

These bugs derived from the complexities involved in correctly implementing incremental rebuild and the problems associated with testing it. Consequently, for 2003 we fixed all known issues with incremental rebuild but subsequently turned it off by default for all projects.

11 short programming problems to stretch your imagination and make sure you are staying on your toes.

(Starting with the simple ones, they get more fun as you move towards the end.)

🧵👇

1. Write a function that reverses an array in place.

In other words, the function should not use an auxiliary array to do the work.

2. Write a function that finds the missing number in an unsorted array containing every one of the other 99 numbers ranging from 1 to 100.

3. Write a function that finds the duplicate number in an unsorted array containing every number from 1 to 100.

Only one of the numbers will appear twice.

4. Write a function that removes every duplicate value in an array.

There could be more than one value duplicated. You should remove all of them leaving a single copy of the value.

I don't think people have quite internalized *how* the US became the global leader in science and technology. It's partially a story of massive global talent migration.

And it's important to get this story right if we want to maintain

Around 1900, the US was a bit of a scientific backwater when compared to Europe. Most of the exciting work was being done in Germany and Austria, especially.

Then came three enormous waves of academic and scientific talent to the US.

1) First came a group of Jewish scientists fleeing persecution.

In a massive own-goal, 1930s Nazi Germany dismissed ~15% of the physicists who made up a stunning 64% (!) of their physics citations.

The group who fleed to the US included intellectual superstars like Albert Einstein, Leo Szilard, John von Neumann, and Edward Teller who formed the backbone of the Manhattan Project.

In a pithy quote, Churchill’s military secretary Sir Ian Jacob is said to have remarked that the Allies won “because our German scientists were better than their German scientists.”

I read two-and-a-half decades worth of Jeff Bezos’s Amazon shareholder letters.

It’s like a mini MBA.

Here I’ve pulled out a free guide for startups, investing, marketing, and “web3”🧵

(It’s a thread, not an ebook)

First, why the focus on web3?

It’s the mid 90’s. A 30-year-old Jeff Bezos is trying to raise money for Amazon. And investors are wondering,

“What’s this internet thing?”

Fast forward, the year is 2022, and folks today are wondering,

“What’s web3?”

Now, a little background…

In 1994, Bezos quit a well paying job to start Amazon.

It wasn’t an easy decision. But Bezos used his famous “regret minimization framework.”

In other words, he didn’t want to be 80 and regret not doing what he really wanted to do.

But what did he want?

Bezos didn’t set out to disrupt retail from the outset.

He simply wanted to come up with a business idea based on the internet and then let the internet grow around it while he kept working on it.

Today, that idea is worth $1.7 trillion and counting.

Moving on to the lessons…

Each year since 1997, Bezos has written an annual letter to Amazon shareholders.

These letters reveal a great deal of lessons and secrets behind his massive success.

So what are they?

I'm excited to share a new growth framework that @danhockenmaier and I have been developing (with help from the amazing @reforge crew)

I've been finding myself coming back to this framework often when talking to founders about growth.

Thread

1/ As a startup, it's essential that you, and your team, have a clear understanding of how your business is likely to grow. We call this building a Growth Model. With this, you'll know which growth investments to make right away, which to avoid, and which to double-down on.

2/ Our advice is to think about your business like a high-performance race car. The same four components that help a car drive faster also help your business grow:

1. ⚙️ The (Growth) Engine: Self-sustaining growth loops that drive most of your growth (e.g. virality, perf marketing, content, sales)

2. 💥 Turbo boosts: One-off events that accelerate growth temporarily but don’t last (e.g. PR, events, Super Bowl ads)

3. 💧 Lubricants: Optimizations that make the growth engine run more efficiently (e.g. improved conversion, a stronger brand, higher customer retention).

4. ⛽ Fuel: The input that your engine requires to run (e.g. capital, content, users).

Ok, I’ve told this story a few times, but maybe never here. Here we go. 🧵👇

Wish I had the audio of Rush Limbaugh telling me off on the phone on his show when I was six. In the meantime, RIP.
— Shannon Woodward (@shannonwoodward) February 17, 2021

I was about 6. I was in the car with my mother. We were driving a few hours from home to go to Orlando. My parents were letting me audition for a tv show. It would end up being my first job. I was very excited. But, in the meantime we drove and listened to Rush’s show.

There was some sort of trivia question they posed to the audience. I don’t remember what the riddle was, but I remember I knew the answer right away. It was phrased in this way that was somehow just simpler to see from a kid’s perspective. The answer was CAROUSEL. I was elated.

My mother was THRILLED. She insisted that we call Into the show using her “for emergencies only” giant cell phone. It was this phone:

I called in. The phone rang for a while, but someone answered. It was an impatient-sounding dude. The screener. I said I had the trivia answer. He wasn’t charmed, I could hear him rolling his eyes. He asked me what it was. I told him. “Please hold.”

Tesla posted a new video about their secret Kato Road 4680 cell production lines a couple of days ago, and it contains a couple of technological gems I haven't seen widely mentioned elsewhere yet, so here's an attempt at listing these new disclosures.

1/

2/

The first thing is that there appear to be no human workers/operators whatsoever in the main production process.

To the left is an image of line workers handling finished cells in a traditional facility. To the right is the 100% automated conveyance system Tesla has.

3/

Here's how their 4680 cells are transported in racks of 8x8 cells: 64 cells each.

These standardized racks likely interface into automated pack production machines, made by Tesla Grohmann, or get directly integrated into the die-cast underbody (structural battery pack).

4/

There's an interesting detail in one of the frames: glimpse of a facility worker observing an industrial robot moving a rack.

5/

What is interesting is that:

✅ Cell production facilities are Class 7 clean rooms, while the worker doesn't wear the usual "bunny suit" protective gear.
✅ There's a barrier between the worker and the robot: likely separating clean-room air from unprotected air.

A quick thread on intelligence analysis in the context of cyber threat intelligence. I see a number of CTI analysts get into near analysis paralysis phases for over thinking their assessments or over obsessing about if they might be wrong. (1/x)

Consider this scenario. A CTI analyst identifies new intrusions and based on the collection available and their expertise note that the victims are all banks. Their consumer wants to know when threats specifically target banks (not just that banks are victims).

The CTI analyst has, from their collection, at this time, and based on their expertise enough to make an activity group (leveraging the Diamond Model in this example) that meet's the requirement of their consumer. So what's the problem?

The CTI analyst begins to over think it. "What if I had more collection? Would my analysis change? I really don't *know* they aren't also targeting mining companies in Australia as I don't have collection there."

The analyst knows their analysis is going to be shared. Maybe even public. "What if another team or professional intelligence firm has more collection and ends up noting that it isn't banking specific at all. Banks are victims, not targets. Will my consumer distrust me later?"

Wellcome to our virtual walk from Ambleside to Howtown on Lake Ullswater. I’ve based the route on #HadriansHighWay by @fellranger1 which he uses a variant to the main route. Books can be bought direct or through @VindolandaTrust

A view of #Ambleside from Wansfell our starting point in the heart of the #LakeDistrict @CumbriaMagazine

We can start at the roman fort at the edge of #Windermere. The Romans stated to push into the lakes in the early 90’s AD, this fort dates to the rebuild in Hadrian’s Reign possibly after warfare which brought about #HadriansWall #Ambleside

The #Ambleside posting wasn’t always a peaceful one as the gravestone in the @ArmittMuseum shows one man was killed “in the fort”

Time to leave and head out of town passing this scale model of the famous Bridge House in #Ambleside #virtualwalk

Thread: Here's the most fun & frivolous tech news today: Railway Operation Depot in the Chinese city Dalian just published an article on their harrowing journey racing to restore the old version of Flash after Adobe's ban, which collapsed their system and paralyzed the railway /1

The article was written a bureaucratic, propaganda, war diary style, with a detailed timeline down to minutes. "Jan 12, 8:16, Depot received malfunction report. The computer system stopped displaying pages...within 30 mins, computers in the entire depot had the same prob" /2

"After calls and online searches, we identified the source of the issue is American company Adobe's comprehensive ban of Flash content" /3

"8:41, IT department held an emergency meeting & took on four urgent measures: 1. informed supervisors and higher-ups 2. immediately started searching for alternatives to solve page inaccessible issue 3. founded a software task force 4. founded a hardware task force" /4

..."12:10 we temporarily maintained the stability of the depot"
..."13:00 a second crisis meeting was held to address three deeply rooted issues"
..."14:11 another crisis erupted. We are no longer able to print pages, again" /5

This is one reason why I quit robotics. I thought it was like....you can work and build fun stuff...but when we went to regional championships there was the FREAKING MILITARY??? And Lockheed Martin and Delta. And they were ALL like....we make planes for the military >:)

i'll never forget my programming teacher who was like a senior dev at IBM and decided he was done writing missile guidance software

when he was telling us this he said "i just woke up one morning and it struck me that i was a murderer. so i quit." https://t.co/Ygqqz0ljWU

Me: am I gonna build a space ship!?

Robotics fair: No bich! You live in georgia!! Now help us build these aerial bombers and military excavation robots! :))

Me:

Like both delta and Lockheed Martin are here and several large military bases so we actually got to visit delta hangers where they make the planes and I was like wow! Planes! And then later i found out airlines are big jerks and make stuff for the airforce.

I wish I would've known I could still probably build spaceships....but idk I was like 15 I didn't know shit. I was just like....I don't see any spaceships!???
I liked the commercial planes...planes are a lot here in Georgia theres a school for it and they have their own airport.

We went there it was cool. Its in the country tho because its a tiny airport for regional flights so the students learn how a control tower works. The control tower is super cool.
