Nice looking ebike...

[Adrien Lelièvre @Lelievre_Adrien]

Wow. Ce prototype de l'opérateur Bond Mobility ne ressemble à rien de connu à ce jour sur le marché du vélo en libre-service. Curieux de voir s'il sera un jour déployé 🚲⚡

Signal will be easy to pinpoint from orbit by the constellation. Perfect opportunity for a rod-from-god. Though a drone is an easier and more prosaic solution.

1/3 According to open sources, Russians have developed a jammer for Starlink satellites: "The countermeasure system is named "Volna Kupol Garant." This EW complex consists of an array of sat antennas and targets eight communication channels, each with a bandwidth of 62.5 MHz." https://t.co/LICal1hLdS

You know you're old when you saw this in theaters . . .

[Kitten 🐈 @kitten_beloved]

Finally watched this last night, now I get why you guys bring it up all the time

[Steve Anderson @Rashomon2]

Yes

The lesson I take from the SpaceX IPO is that the only thing stopping us from solving arbitrarily difficult problems is extreme creativity in business models.

No amount of tax and spend programs got us reusable rockets and great electric cars. Customer delight is a necessary precondition for success.

There seems to be some discussion around whether successful entrepreneurs should give up control of their companies so they can subsidize some philanthropic venture that otherwise has no value prop sufficient to run it as a business where customers voluntarily exchange money for goods and services at a competitive and reasonable price.

This misses the point. Transformational products deliver tangible value at 1000x the rate of charities whose value cannot be tested in the market place. Think about the undeniable value of the smart phone, satellite Internet, electric consumer devices, etc etc.

I think the transformational moment for SpaceX was when Elon stepped away from the philanthropic Mars greenhouse concept and fixed his resolve on unlocking radically better rockets for humanity. The greenhouse would have been, at best, a neat trick. Falcon and Starship give humanity a durable economic engine to maintain and improve access to space, forever.

@marcorandazza Have her take the MSF Basic Riding Class — better yet, take it with her. You get about 8 hours on provided small bikes in a parking lot along with classroom training. You’ll know how serious she is afterwards, and she’ll get necessary mc safety training.

[Steve Anderson @Rashomon2]

I believe you

[John Bourscheid 🇺🇸 🚀 @bourscheid]

I really don’t understand true greed. If I was worth $1 trillion, you’d have to physically stop me from solving as many of the world’s problems as possible.

Everyone would have a home, food on the table, proper healthcare, happiness.

I just don’t get it.

Today is the day to see who thinks zero-sum and those who do not.

[Steve Anderson @Rashomon2]

We will never cut our way to zero carbon. This mentality deserves everything that is going to happen to it.

Astonishing Telegraph story.

These are going to be an aftermarket thing soon.

SBKでは来季からブレーキはブレンボが独占供給（オフィシャルブレーキサプライヤー）になると公式発表。またブレンボでは、公道走行前提となる市販車向けのカーボンブレーキシステム「HYCTION」を発表。公道からレースまで使用できる汎用性を持った、初の市販2輪車用カーボンブレーキとなる。モノがカーボンだけあって軽量化の効果は凄まじく、鋳鉄のディスクに比べてシステム全体で1.5kgもの軽量化が図られているそうだ。

カーボンディスクはその効きと引き換えに温度管理が難しく、一定の高温レベルに達しないと制動力が発生しないとされている。それが市販車への搭載を阻んできたのだが、遂に技術的な解決策が見つかったということだろう。

しかし公道でカーボンディスクが使える時代が来ましたか。そのフィーリングがどんなものか、一度は試してみたいものである（間違いなく目の玉飛び出るほど高いよ！）

The intent of the above post was simply to confirm that there are readers out there that appreciate the work. My ex-wife and brother often agreed on the non-SF novels they liked and generally had very good taste. I only recommended outstanding SF to either, because of their high standards.

@MorlockP What Alpha Schools is going with its gifted program is what we should be aiming for. I'm retroactively jealous. However, I'm sure while Alpha is doing much better than public schools, the performance at their regular schools is almost certainly driven somewhat by self-selection.

[Steve Anderson @Rashomon2]

@MorlockP Yep, but I can't help just needlessly pointing out the delta-T is really important . . . not that the OP/idiot cares.

[Steve Anderson @Rashomon2]

@MorlockP Stefan-Boltzman applies. While your T for a processor isn't high, your To (background temp) can be very, very low if your radiator is shaded from the sun and pointing toward empty space (not the earth), making radiative heat transfer far more effective than on earth.

As a journalist, I embedded with multiple groups of migrants during 2015-16 "Syrian" wave (only about a third were fleeing the civil war in Syria, from my observation). I even lived in a smuggler's safe house in Istanbul, waiting for weather conditions to permit a dinghy crossing from Izmir to Lesbos.

I went into that experience basically an open-borders person and left a restrictionist. Merkel's flinging the gates to more than 1 million newcomers was madness, sheer madness.

Even if these were the most aspirational migrants imaginable --- and they weren't, gotta be honest --- the numbers, the cultural distance, and the conditions of European society should've prompted a rethink. But no. Wir schaffen das.

I tried to put myself in the shoes of native working classes in the transit countries (the Balkans, Hungary, etc.) and the recipients (Germany, Sweden, etc.). It was obvious that they would experience it as a cataclysm.

Even if most wouldn't become victims of crime, this many newcomers were bound to generate acute incohesion experienced at the street, social services, and housing levels, mostly burdening the native poor and those on the lower rungs of the labor market.

The engine of assimilation, not particularly robust in most of Europe to begin with, breaks down in the face of sheer numbers. In retrospect, I've come to believe that this was the single worst and most consequential decision taken by European leaders in the 21st century.

I don't understand it. I remember @DouglasKMurray telling me at the early stages that the best way to help was in-country, meaning humanitarian assitance in the Middle East and North Africa, not by bringing them over. He was 100% correct.

American Fire Truck Myths: Pump Size

One of many “reasons” preventing right-sized fire trucks is pump size. We have wood buildings, we need more water flow. A common EU engine pumps 790-925 gallons/minute while common U.S. is 1,500. (NFPA requires 750)

Here is a picture of a 1,500gpm pump ~with~ the transmission required for the added flow rate. It’s ~32” tall, 13” wide, and 23” deep in total. For comparison it’s roughly the same volume as this 2-drawer file cabinet.

The needed pump isn’t justifying 7-8’ more length. It’s a convenient technical-sounding excuse when asked to consider being more disciplined within a slightly smaller footprint to improve public safety where we actually can.

Apple would have had to start building cars if they were ever going to succeed in the auto biz. I have little faith that an Apple car and an Apple car manufacturing process could have emerged like Botticelli's Venus from an ocean of brilliant industrial design and R&D. There had to be sordid lessons learned from actually building vehicles and iterating to find product-market fit.

Waymo has purchased Apple's 5,500-acre self-driving car Arizona proving ground for $220 million. The location includes a 115-acre city course, a 35-acre vehicle dynamics area, a 4-mile oval track, and a freeway course for AV testing.

Apple spent 10 years and $10 billion on its self-driving car project before cancelling it because it couldn't achieve its objectives.

The same country that put humans on the Moon in 1969 now takes an average of 4.5 years to approve major infrastructure permits.. longer than it took to build the Panama Canal. 

Transmission lines average 10 years from permitting to completion. The bottleneck to abundance is not technology, but BUREAUCRACY!
