The Chinese Communist Party celebrated its centenary on the 1st of July, 2021. For such a celebration, clear skies and clean air would be ideal. For the capable nation-state, however, one needn’t hope against the whims of the weather. One can simply control it instead!
A recent paper released by Tsinghua University indicated that China had used cloud seeding in order to help create nicer conditions for its 100-year celebration. Weather modification techniques have been the source of some controversy, so let’s explore how they work and precisely what it was that China pulled off.
On December 5th, someone by the IRC nickname of [ubuntu] joined the Pine64 Discord’s #pinephone channel through an IRC bridge. In the spirit of December gift-giving traditions, they have presented their fellow PinePhone users with an offering – a “Snake” game. What [ubuntu] supposedly designed had the potential to become a stock, out-of-the-box-installed application with a small but dedicated community of fans, modders and speedrunners.
Unfortunately, that would not be the alternate universe we live in, and all was not well with the package being shared along with a cheerful “hei gaiz I make snake gaem here is link www2-pinephnoe-games-com-tz replace dash with dot kthxbai” announcement. Shockingly, it was a trojan! Beneath layers of Base64 and Bashfuscator we’d encounter shell code that could be in the “example usage” section of a modern-day thesaurus entry for the word “yeet“.
One of the hottest topics in the world of scientific publishing over the last couple of decades has been the growing pressure to release the fruits of public-funded scientific research from the paywalled clutches of commercial publishers. This week comes news of a new front in this ongoing battle, as a group of Indian researchers have filed an intervention application with the help of the Indian Internet Freedom Foundation in a case that involves the publishers Elsevier, Wiley, and the American Chemical Society who have filed a copyright infringement suit against in the Delhi High Court against the LibGen & Sci-Hub shadow library websites.
The researchers all come from the field of social sciences, and they hope to halt moves to block the websites by demonstrating their importance to research in India in the light of unsustainable pricing for Indian researchers. Furthermore they intend to demonstrate a right of access for researchers and teachers under Indian law, thus undermining the legal standing of the original claim.
We’re not qualified to pass comment on matters of Indian law here at Hackaday, but we feel this will be a case worth watching for anyone worldwide with an interest in open access to research papers. If it can be established that open access shadow libraries can be legal in a country the size of India, then it may bring to an end the somewhat absurd game of legal whack-a-mole that has raged over the last decade between the sites on their untouchable Russian servers and heavy-handed academic publishers who perhaps haven’t moved on from their paper publishing past. It’s time for a fresh start with the way academic publishing works, and maybe this will provide the impetus for that to happen.
Let’s launch into a round-up of stories that are out of this world, as we take a look at what’s happening in the realm of space exploration.
Ten Billion Dollars For A Telescope? Don’t Drop It!
Perhaps the most highly anticipated space mission of the moment is the James Webb Space Telescope, an infra-red telescope that will be placed in an orbit around the Earth-Sun L2 Lagrange point from which it will serve as the successor to the now long-in-the-tooth Hubble telescope. After many years of development the craft has been assembled and shipped to French Guiana for a scheduled Ariane 5 launch on the 22nd of December. We can only imagine what must have gone through the minds of the engineers and technicians working on the telescope when an unplanned release of a clamp band securing it to the launch vehicle adapter sent a vibration throughout the craft. Given the fragility of some of its components this could have jeopardised the mission, however after inspection it was found that no damage had occurred and that space-watchers and astronomers alike can breathe easy.
Sales of electric vehicles continue to climb, topping three million cars worldwide last year. All these electric cars need batteries, of course, which means demand for rechargeable cells is through the roof.
All those cells have to come from somewhere, of course, and many are surprised to learn that automakers don’t manufacture EV batteries themselves. Instead, they’re typically sourced from outside suppliers. Today, you get to Ask Hackaday: why aren’t EV batteries manufactured by the automakers themselves?

By any metric you care to use, this is a very exciting time for America’s space program. NASA is refocusing their efforts towards the Moon and beyond, SpaceX is launching routine crew and cargo flights to the International Space Station with reusable rockets, and if you’ve got deep enough pockets, there are now multiple companies offering suborbital pleasure trips requiring little more than a few hours worth of training. It’s taken longer than many people had hoped, but it seems we’re finally making the confident strides necessary to truly utilize space’s vast resources.
But things are just getting started. A new generation of massive reusable rockets are currently being developed, which promise to make access to space cheaper and faster than ever before. We’ve seen quite a bit of SpaceX’s Starship, thanks in no small part to the dramatic test flights that the media-savvy company has been regularly live streaming to YouTube. But Blue Origin, founded by Amazon’s Jeff Bezos, has been far more secretive about their New Glenn. That is, until now.
GS1 under construction in Florida.
On November 8th, Blue Origin rolled out their GS1 simulator for the New Glenn’s first stage. This stand-in for the real rocket will never fly, but it’s designed to perfectly recreate the dimensions, center of gravity, and mass, of the real thing. Ground teams will use the GS1 to practice safely transporting the booster, which is approximately half the length of the Saturn V, from their production facility to Launch Complex 36 (LC-36) at Cape Canaveral. It will also be used to test the fit and function of various pieces of ground support equipment, and eventually, the second stage stacking procedure.
For the uninitiated, it might seem like this is a lot of fuss over what’s ultimately just a hollow metal tube. But the introduction of a test article such as this has traditionally been a major milestone during the design and construction of rockets and spacecraft, dating back to the “boilerplate” test capsules used during the Mercury, Gemini, and Apollo programs; a sure sign that what was just an idea is now becoming a reality.
NASA first landed a human on the moon back in 1969, and last achieved the feat in December 1972. In the intervening years, there have been few other missions to Earth’s primary natural satellite. A smattering of uncrewed craft have crashed into the surface, while a mere handful of missions have achieved a soft landing, with none successful from 1976 to 2013.
However, NASA aims to resume missions to the lunar surface, albeit in an uncrewed capacity at this stage. And you won’t have to wait very long, either. The world’s premier space agency aims to once again fly to the Moon beginning in February 2022.
