Lol. ..about as much as I traveled London during my layover at Heathrow.. Cheers, ahb.

Hi Andrew, Your LinkedIn profile is an integral part of how you present your professional self to the world. That's why we believe it's important to inform you that due to the presence of prohibited content located in the Summary section of your LinkedIn profile, your profile and your public activity, such as your comments and items you share with your network, will not be made viewable in China. Your profile and activity continues to remain viewable throughout the rest of the countries in which LinkedIn is available. We will work with you to minimize the impact and can review your profile’s accessibility within China if you update the Summary section of your profile. But the decision whether to update your profile is yours. In February 2014, we began offering a localized version of LinkedIn in China. We believe that people everywhere can benefit from Chinese individuals connecting with each other and LinkedIn members in other parts of the world, and that the creation of economic opportunity can have a profound impact on their lives and the lives of their families and communities. While we strongly support freedom of expression, we recognized when we launched that we would need to adhere to the requirements of the Chinese government in order to operate in China. As a reminder, your profile will remain viewable throughout the rest of the countries in which LinkedIn is available. If you have any questions, please contact Customer Service.

Why did Slashdot remove the Chinese characters in my previous post? Censorship on Slashdot?

I just updated my LinkedIn page with the following text: The Tiananmen Square protests, known as the June Fourth Incident in China (Chinese: ; pinyin: liùsì shìjiàn), were student-led demonstrations held in Tiananmen Square, Beijing during 1989. In what is known as the Tiananmen Square Massacre (Chinese: ; pinyin: Tin'nmén dà túsh), troops armed with assault rifles and accompanied by tanks fired at the demonstrators and those trying to block the military's advance into Tiananmen Square. The protests started on April 15 and were forcibly suppressed on June 4 when the government declared martial law and sent the People's Liberation Army to occupy parts of central Beijing. Estimates of the death toll vary from several hundred to several thousand, with thousands more wounded.[2][3][4][5][6][7] The popular national movement inspired by the Beijing protests is sometimes called the '89 Democracy Movement (Chinese: ; pinyin: Bji mínyùn) or the Tiananmen Square Incident (Chinese: ; pinyin: Tin'nmén shìjiàn). If everyone does it, maybe it will make a difference!

Unless you reach orbital velocity, you might as well just ride the vomit comet. In 1957, astronauts began training on planes that simulate weightlessness by making roller-coaster-like maneuvers in the air. The simulation makes some passengers nauseous, which inspired the nickname "Vomit Comet." -> https://www.space.com/37942-vo... You have about 25 seconds of weightlessness out of 65 seconds of flight in each parabola. During such training, the airplane typically flies about 40–60 parabolic maneuvers. Avg of 50 parabolic maneuvers, so that gives: 50 x 25s = 1250s of weightlessness. Much more than you will get on a lame suborbital flight with 3.5 to 4 minutes of weightlessness.. :-o

Could they do better than a giant Gundam puppet? What's the largest bipedal robot ever built? What's the largest feasible one? Is it technically possible to build something like this? What are the limits of modern mechanical engineering? Anybody know an upper limit? Cheers, Andrew

A cantenna (a portmanteau blending the words can and antenna) is a homemade directional waveguide antenna, made out of an open-ended metal can. Cantennas are typically used to increase the range (or discovery) of Wi-Fi networks. The cylinder portion of the can may consist of metal-coated paperboard. Although some designs are based on a Pringles potato chips can, this tube is too narrow to increase the 2.4 GHz signal by a useful amount, although at 5 GHz it would be about the right size.[1] However, a cantenna can be made from various cans or tubes of an appropriate diameter.[2] Some designs include a pole mount to elevate the cantenna.[3] https://en.wikipedia.org/wiki/... http://www.cantenna.com/Canten...

After 10^100 years, most of the matter in the universe will have been sucked up into gigantic black holes that eventually evaporate due to Hawking radiation. The remainder evaporate due to things like proton decay. When all the mass of the universe has converted to photons, something amazing will happen. Due to the mass energy relationship (e=mc^2), mass is proportional to energy. Due to Planck-Einstein relation (E=h), energy is proportional to frequency (time). Since distance is defined as how far a photon can travel in a unit of time, it all goes to zero when the mass finally leaves, and the universe instantly contracts into the next Big Bang. This concept is called conformal cyclic cosmology (CCC), a cosmological model in the framework of general relativity, advanced by the theoretical physicist Roger Penrose

There was a comment: "There aren't enough metal-rich asteroids to account for the quantity of metals they found." So I gave a counter example (16/Psyche). It's reasonable to assume in the past several billion years there have been others similar in size and composition. -AB

I obviously meant 16/Psyche type objects, and similar sized fragments, which would have been more prevalent in the early solar system..

How do they know how many metal rich asteroids were around billions of years ago? Also, there is this: https://en.wikipedia.org/wiki/... It alone could account for all the metal, I think.. -AB

I think that metal-rich asteroids and planet-core fragments could easily explain the metal in the moon's crust. I didn't read the paper, but how could you rule it out? -AB.

Other than the cruise companys not liking being associated with the virus, why not? They are all sitting idle now anyway..

Anyone who does a minimal amount of background research will discover these have been on GitHub for 7 years: https://github.com/maduce/foss... Cheers, Andrew.
