2022's Geeky 'Advent Calendars' Tempt Programmers with Coding Challenges and Tips 11
- The HTMHell site — which bills itself as "a collection of bad practices in HTML, copied from real websites" — decided to try publishing 24 original articles for their 2022 HTMHell Advent Calendar. Elsewhere on the way there's the Web Performance Calendar, promising daily articles for speed geeks. And the 24 Days in December blog comes to life every year with new blog posts for PHP users.
- The JVM Advent Calendar brings a new article daily about a JVM-related topic. And there's also a C# Advent calendar promising two new blog posts about C# every day up to (and including) December 25th.
- The Perl Advent Calendar offers fun stories about Perl tools averting December catastrophes up at the North Pole. (Day One's story — "Silent Mite" — described Santa's troubles building software for a ninja robot alien toy, since its embedded hardware support contract prohibited unwarrantied third-party code, requiring a full code rewrite using Perl's standard library.) Other stories so far this December include "Santa is on GitHub" and "northpole.cgi"
- The code quality/security software company SonarSource has a new 2022 edition of their Code Security Advent Calendar — their seventh consecutive year — promising "daily challenges until December 24th. Get ready to fill your bag of security tricks!" (According to a blog post the challenges are being announced on Twitter and on Mastadon.
- Just as the Perl community spawned another language named Perl 6 — now called Raku — there's also a Raku-themed advent calendar. (It's now at a new URL, though it's been running since 2009.) Day Three's post tells the story of Santa and the Rakupod Wranglers.
- "24 Pull Requests" dares participants to make 24 pull requests before December 24th. (The site's tagline is "giving back to open source for the holidays.") Over the years tens of thousands of developers (and organizations) have participated — and this year they're also encouraging organizers to hold hack events.
- The Advent of JavaScript and Advent of CSS sites promise 24 puzzles delivered by email (though you'll have to pay if you also want them to email you the solutions!)
- TryHackMe.com has its own set of darily cybersecurity puzzles (and even a few prizes).
- For 2022 Oslo-based Bekk Consulting (a "strategic internet consulting company") is offering an advent calendar of their own. A blog post says its their sixth annual edition, and promises "new original articles, podcasts, tutorials, listicles and videos every day up until Christmas Eve... all written and produced by us - developers, designers, project managers, agile coaches, management consultants, specialists and generalists."
Whether you participate or not, the creation of programming-themed advent calendar sites is a long-standing tradition among geeks, dating back more than two decades. (Last year Smashing magazine tried to compile an exhaustive list of the various sites serving all the different developer communities.)
But no list would be complete without mentioning Advent of Code. This year's programming puzzles involve everything from feeding Santa's reindeer and loading Santa's sleigh. The site's About page describes it as "an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like."
Now in its eighth year, the site's daily two-part programmig puzzles have a massive online following. This year's Day One puzzle was solved by 178,628 participants...
Stanford Investigates Its President Over Allegations of Past Research Misconduct (msn.com) 22
More from the Washington Post: The university launched the inquiry after the Stanford Daily, a campus newspaper, reported that a well-known research journal was looking into concerns raised about a 2008 paper co-authored by Marc Tessier-Lavigne. The Daily reported that in addition to the paper in the European Molecular Biology Organization Journal, there were questions about other published research.
Some of those complaints were first made many years ago, and Tessier-Lavigne had tried to correct papers at one journal in 2015, according to its editor.... Tessier-Lavigne said in a statement that he supports the inquiry. "Scientific integrity is of the utmost importance both to the university and to me personally," Tessier-Lavigne said. "I support this process and will fully cooperate with it, and I appreciate the oversight by the Board of Trustees...."
Elisabeth Bik, who had been a staff scientist at Stanford doing postdoctoral microbiology research until 2016 and is now a well-known research integrity consultant who specializes in photographic images, said she heard about the questions about some papers of which Tessier-Lavigne is one of the authors a few years after they were first raised, and identified additional possible problems.
Most appeared to be minor concerns, and they could have been honest mistakes, she said. This week, Bik said, she spotted a more troubling instance in a paper from 1999 with multiple authors where it appeared photos had been altered, which she said was suggestive of copying and pasting.
The Los Angeles Times describes Tessier-Lavigne as "a neuroscientist and biotech entrepreneur widely known for his Alzheimer's research" who "has authored or co-authored about 300 scientific papers."
Two Minerals Never Before Been Seen On Earth Found Inside 17-Ton Meteorite (livescience.com) 14
The researchers classified El Ali as an Iron IAB complex meteorite, a type made of meteoric iron flecked with tiny chunks of silicates. While investigating the meteorite slice, details of the new minerals caught the scientists' attention. By comparing the minerals with versions of them that had been previously synthesized in a lab, they were able to rapidly identify them as newly recorded in nature. The researchers plan to investigate the meteorites further in order to understand the conditions under which their parent asteroid formed. The team is also looking into material science applications of the minerals. However, future scientific insights from the El Ali meteorite could be in peril. The meteorite has now been moved to China in search of a potential buyer, which could limit researchers' access to the space rock for investigation. "Whenever you find a new mineral, it means that the actual geological conditions, the chemistry of the rock, was different than what's been found before," Chris Herd, a professor in the Department of Earth and Atmospheric Sciences at the University of Alberta, said in a statement. "That's what makes this exciting: In this particular meteorite you have two officially described minerals that are new to science."
iFixit Put Up a Right To Repair Billboard Along New York Governor's Drive To Work (pirg.org) 32
The Albany Times Union editorialized twice for the governor to sign the bill, recently noting that the bill has come under intense opposition from manufacturers: "Meanwhile, lobbyists, big corporations and a few trade organizations are pressing for a veto ... Ms. Hochul must sign the bill, and then lawmakers should get to work passing an expanded version that includes all the products that were needlessly stripped from the original. Big corporations and the lobbyists they hire won't be happy, but that shouldn't matter a bit."
As US Investigates Ticketmaster, Botched Sale of Taylor Swift Tickets Fuels Monopoly Criticisms (npr.org) 94
America's Justice Department "has opened an antitrust investigation into the owner of Ticketmaster," reports the New York Times. But the investigation "predates the botched sale" and "is focused on whether Live Nation Entertainment has abused its power over the multibillion-dollar live music industry." The new investigation is the latest scrutiny of Live Nation Entertainment, which is the product of a merger between Live Nation and Ticketmaster that the Justice Department approved in 2010. That created a giant in the live entertainment business that still has no equals in its reach or power.... The debacle involving Ms. Swift's concert tickets this week has exacerbated complaints in the music business and in Washington that Live Nation's power has constrained competition and harmed consumers.
Or, as NPR puts it, "The frenzy has brought renewed scrutiny to the giant Ticketmaster, which critics have long accused of abusing its market power at the expense of consumers." Would-be concertgoers have complained vocally about recent incidents with near-instant sellouts and skyrocketing prices, and artists like Pearl Jam and Bruce Springsteen have feuded with it over the decades. One common complaint is that there doesn't seem to be a clear alternative or competitor to Ticketmaster, especially after it merged with concert provider Live Nation in 2010 (a controversial move that required conditional approval from the U.S. Department of Justice).
Now Tennessee's attorney general, a Republican, is opening a consumer protection investigation into the incident. North Carolina's attorney general announced on Thursday that his office is investigating Ticketmaster for allegedly violating consumers' rights and antitrust laws. And multiple Democratic lawmakers are asking questions about the company's dominance â" not for the first time.... "Taylor Swift's tour sale is a perfect example of how the Live Nation/Ticketmaster merger harms consumers by creating a near-monopoly," tweeted Sen. Richard Blumenthal (D-Conn.), one of several lawmakers who has long called for investigation and accountability into the company, especially after becoming a subsidiary of concert behemoth Live Nation.
The article also cites a Thursday statement from Ticketmaster: The company says that using Verified Fan invite codes has historically helped manage the volume of users visiting the website to buy tickets, though that wasn't the case on Tuesday. "The staggering number of bot attacks as well as fans who didn't have invite codes drove unprecedented traffic on our site, resulting in 3.5 billion total system requests â" 4x our previous peak," it said, adding that it slowed down some sales and pushed back others to stabilize its systems, resulting in longer wait times for some users.
It estimates that about 15% of interactions across the website experienced issues, which it said is "15% too many."
The Tuesday sale also broke Ticketmaster's record for most tickets sold for an artist in a single day," reports People, "selling two million tickets."

Swedish Engineer Creates Playable Accordion From 2 Commodore 64 Computers (arstechnica.com) 26
A fair amount of custom software engineering and hardware hackery went into making the Commodordion possible, as Akesson lays out in a post on his website. It builds off of earlier projects (that he says were intentionally leading up to this one), such as the Sixtyforgan (a C64 with spring reverb and a chromatic accordion key layout) and Qwertuoso, a program that allows live playing of the C64's famous SID sound chip.
So how does the Commodordion work? Akesson wired up a custom power supply, and when he flips the unit on, both Commodore 64 machines boot (no display necessary). Next, he loads custom music software he wrote from a Commodore Datasette emulator board into each machine. A custom mixer circuit board brings together the audio signals from the two units and measures input from the bellows to control the volume level of the sound output. The bellows, composed of many 5.25-inch floppy disks cut and taped into shape, emit air through a hole when squeezed. A microphone mounted just outside that hole translates the noise it hears into an audio envelope that manipulates the sound output to match. The Commodordion itself does not have speakers but instead outputs its electronic audio through a jack.
JavaScript Still Tops Python and Java in RedMonk's Latest Rankings, While Go and TypeScript Rise (redmonk.com) 54
Their methodology? "We extract language rankings from GitHub and Stack Overflow, and combine them for a ranking that attempts to reflect both code (GitHub) and discussion (Stack Overflow) traction." Below are this quarter's results:
1. JavaScript
2. Python
3. Java
4. PHP
5. C#
6. CSS
7. C++
7. TypeScript
9. Ruby
10. C
11. Swift
12. R
12. Objective-C
14. Shell
15. Scala
15. Go
17. PowerShell
17. Kotlin
19. Rust
19. Dart
Their analysis of the latest rankings note "movement is increasingly rare.... the top 20 has been stable for multiple runs. As has been speculated about in this space previously, it seems increasingly clear that the hypothesis of a temporary equilibrium of programming language usage is supported by the evidence.... [W]e may have hit a point of relative — if temporary — contentment with the wide variety of languages available for developers' usage."
And yet this quarter TypeScript has risen from #8 to #7, now tied with C++, benefiting from attributes like its interoperability with an existing popular language with an increased availability of security-related features. "There is little suggestion at present that the language is headed anywhere but up. The only real question is on what timeframe." Unlike TypeScript, Go's trajectory has been anything but clear. While it grew steadily and reasonably swiftly as languages go, it has appeared to be stalled, never placing higher than 14th and having dropped into 16 for the last three runs. This quarter, however, Go rose one spot in the rankings back up to 15. In and of itself, this is a move of limited significance, as the further one goes down the rankings the less significant the differences between them are, ranking-wise. But it has been over a year since we've seen movement from Go, which raises the question of whether there is any room for further upward ascent or whether it will remain hovering in the slot one would expect from a technically well regarded but not particularly versatile (from a use case standpoint) language.
Like Go, Kotlin had spent the last three runs in the same position. It and Rust had been moving in lockstep in recent quarters, but while Rust enters its fourth consecutive run in 19th place, Kotlin managed to achieve some separation this quarter jumping one spot up from 18 to 17.

Lufthansa Changes Mind, Now Says Apple AirTags Are Allowed on Luggage (arstechnica.com) 19
Ars Technica reports on the public relations debacle that then ensued: Outcry, close reading of the relevant sections (part 2, section C) of ICAO guidelines, and accusations of ulterior motives immediately followed. AppleInsider noted that the regulations are meant for lithium-ion batteries that could be accidentally activated; AirTag batteries are not lithium-ion, are encased, and are commonly used in watches, which have not been banned by any airline. The site also spoke with "multiple international aviation experts" who saw no such ban in ICAO regulations. One expert told the site the ban was "a way to stop Lufthansa from being embarrassed by lost luggage...."
Numerous people pointed out that Lufthansa, in its online World Shop, sells Apple AirTags. One Ars staffer noted that Lufthansa had previously dabbled in selling a smart luggage tag, one that specifically used RFID and BLE to program an e-ink display with flight information. On Tuesday, Apple told numerous publications that it, too, disagreed with Lufthansa's interpretation. It went unsaid but was strongly implied that a company that is often the world's largest by revenue would take something like air travel regulations into consideration when designing portable find-your-object devices....
Representatives from the Federal Aviation Administration and Transportation Security Administration said early this week that Bluetooth-based trackers were allowed in checked luggage. The European Union Aviation Safety Agency said its regulations could "not in itself ban or allow" trackers, but airlines could determine their own guidelines.
On Wednesday, Lufthansa walked back the policy under the cover of "The German Aviation Authorities (Luftfahrtbundesamt)," which the airline said in a tweet "shared our risk assessment, that tracking devices with very low battery and transmission power in checked luggage do not pose a safety risk." This would seem to imply either that Lufthansa was acting on that authority's ruling without having previously mentioned it, or that Lufthansa had acted on its own and has now found an outside actor to approve their undoing.
Lufthansa Says Passengers Can't Use Apple AirTags to Track Checked Bags (nytimes.com) 72
Slashdot's original story appears below:
Citing rules issued by the International Civil Aviation Organization (ICAO), German airliner Lufthansa says it is banning activated Apple AirTags from luggage "as they are classified as dangerous and need to be turned off." Slashdot reader AmiMoJo first shared the news with us. The New York Times reports: Lufthansa, a German airline, set off confusion recently after telling passengers that they could not use trackers like Apple AirTags in checked baggage because of international guidelines for personal electronic devices. Apple rejected that interpretation on Tuesday, saying its trackers comply with all regulations. It does not appear that any other airlines are requiring passengers to turn off the trackers, which have become popular as a way to find lost baggage.
Lufthansa found itself in the middle of the issue when reports surfaced in the German news media that the devices were prohibited. Though Lufthansa said it has no desire to prohibit the devices that it deemed safe, the airline seems to have stepped in a mess based on the reading of obscure international guidelines and regulations, with no clear consensus on what is and is not allowed in Europe.
Lufthansa said on Sunday on Twitter that the trackers must be deactivated in checked baggage on its flights, citing the International Civil Aviation Organization's guidelines for dangerous goods as well as the trackers' "transmission function." Shutting off the trackers renders them useless. The airline has not issued a specific policy prohibiting baggage trackers. Rather, it says it is at the mercy of the rules. On Tuesday, the airline said it was "in close contact with the respective institutions to find a solution as quickly as possible." It also indicated its own examination saw no danger from their use. "The Lufthansa Group has conducted its own risk assessment with the result that tracking devices with very low battery and transmission power in checked luggage do not pose a safety risk," said Martin Leutke, a Lufthansa spokesman. "We have never issued a ban on devices like that. It is on the authorities to adapt regulations that right now limit the use of these devices for airline passengers in checked luggage."
In its statement, Apple said that AirTags are "compliant with international airline travel safety regulations for carry-on and checked baggage."
After 23 Years, Weather Channel's Iconic Computerized Channel Is Shutting Down (arstechnica.com) 10
Launched in 1999, Weatherscan currently appears in a dwindling number of local American cable TV and satellite markets. It shows automated local weather information on a loop, generated by an Intellistar computer system installed locally for each market. Declining viewership and the ubiquity of smartphone weather apps are the primary reasons it's going offline. There are also technical issues with maintaining the hardware behind the service. "Weatherscan has been dying a slow death over the course of the last 10 years because the hardware is aging," says Mike Bates, a tech hobbyist who collects and restores Weather Channel computer hardware as part of a group of die-hard fans who follow insider news from the company. "It's 20 years old now, and more and more cable companies have been pulling the service." [...]
Hobbyists like Bates (who goes by "techknight" on Twitter) have collected the hardware necessary to run their own Weatherscan stations out of their homes. Some have also created software that simulates the service in a browser. [...] However, getting Weatherscan to run locally was a team effort, primarily by friends named Ethan, Brian, and Jesse. One of the Intellistar computer models behind the service runs FreeBSD on a Pentium 4-based PC in a blue rack-mount enclosure. It includes an ATI card for generating the graphics and a proprietary PowerPC-based card that pulls it all together to make it broadcast-ready. To get Weatherscan working at home, the group of friends found decommissioned Intellistar units on eBay and used forensic tools to reconstruct data from the hard drives, piecing together a working version of the Weatherscan software from multiple sources. Since then, they have exhibited their work at shows like the Vintage Computer Festival Midwest last month.

San Francisco Passes Controversial Surveillance Plan (sfgate.com) 46
Under the new policy, police can access up to 24 hours of live video of outdoor footage from private surveillance cameras owned by individuals or businesses without a warrant as long as the camera's owner allows it. Police must meet one of three outlined criteria to use their newfound power: they must be responding to a life-threatening emergency, deciding how to deploy officers in response to a large public event or conducting a criminal investigation that was approved in writing by a captain or higher-ranking police official. The trial will last 15 months. If supervisors wish to extend or revise the policy, they must take a second vote. "I know the thought process is, 'Just trust us, just trust the police department.' But the reality is people have been violating civil liberties since my ancestors were brought here from an entirely, completely different continent," Walton, the board president and District 10 representative, said.
San Francisco District Attorney Brooke Jenkins added: "I believe this policy can help address the existence of open-air drug markets fueling the sale of the deadly drug fentanyl. Drug dealers are destroying people's lives and wreaking havoc on neighborhoods like the Tenderloin. Mass organized retail theft, like we saw in Union Square last year, or targeted neighborhood efforts like we've seen in Chinatown is another area where the proposed policy can help."
New Avatar Movie and Star Wars TV Trailers Revealed at D23 Conference (sfgate.com) 53
And the studio presented a trailer for Tales of the Jedi, which offers six original shorts about Ahsoka and Dooku, and arrives October 26. Fans also got a glimpse, though not a trailer, showing Jude Law, who's starring in Star Wars: Skeleton Crew, a story about a group of younglings lost in space.
Also revealed was a "developer update" trailer for the upcoming mobile game Avatar: Reckoning, as part of the news about other franchises: James Cameron called in to the event from New Zealand to discuss Avatar: The Way of Water, and the crowd was given 3D glasses to watch some breathtaking footage [from] Cameron's long-awaited sequel... ahead of its December 16 release.
An exclusive clip from The Ant-Man and the Wasp: Quantumania featured Kang holding Cassie Lang hostage and trying to force Scott to steal something for him. Also featured: Bill Murray!

IEEE's Top Programming Languages of 2022: Python (and SQL) (ieee.org) 76
Java also remains popular, as does Javascript, the latter buoyed by the ever-increasing complexity of websites and in-browser tools (although it's worth noting that in some quarters, the cool thing is now deliberately stripped-down static sites built with just HTML and simple CSS).
But among these stalwarts is the rising popularity of SQL. In fact, it's at No. 1 in our Jobs ranking, which looks solely at metrics from the IEEE Job Site and CareerBuilder. Having looked through literally hundreds and hundreds of job listings in the course of compiling these rankings for you, dear reader, I can say that the strength of the SQL signal is not because there are a lot of employers looking for just SQL coders, in the way that they advertise for Java experts or C++ developers. They want a given language plus SQL. And lots of them want that "plus SQL...."
Job listings are of course not the only metrics we look at in Spectrum. A complete list of our sources is here, but in a nutshell we look at nine metrics that we think are good proxies for measuring what languages people are programming in. Sources include GitHub, Google, Stack Overflow, Twitter, and IEEE Xplore [their library of technical content]. The raw data is normalized and weighted according to the different rankings offered — for example, the Spectrum default ranking is heavily weighted toward the interests of IEEE members, while Trending puts more weight on forums and social-media metrics.
Python is still #1 in their "Trending" view of language popularity, but with Java in second place (followed by C, JavaScript, C++ and C# — and then SQL). PHP is next — their 8th-most-trending language, followed by HTML, Go, R, and Rust.
Heroku Announces Plans To Eliminate Free Plans, Blaming 'Fraud and Abuse' (techcrunch.com) 9
[...] Wise went on to note that Heroku will be announcing a student program at Salesforce's upcoming Dreamforce conference in September, but the details remain a mystery at this point. For the uninitiated, Heroku allows programmers to build, run and scale apps across programming languages including Java, PHP, Scala and Go. Salesforce acquired the company for $212 million in 2010 and subsequently introduced support for Node.js and Clojure and Heroku for Facebook, a package to simplify the process of deploying Facebook apps on Heroku infrastructure. Heroku claims on its website that it's been used to develop 13 million apps to date.
Bay Area Startup Wants To Make Call Center Workers Sound 'White and American' (sfgate.com) 174
Eventually, the company wants to expand beyond call centers by changing accents on consumer video and audio calls; Sanas has even mentioned an interest in film and TV. New voices are in the works, too: Someday, workers' accents may be "translated" into a Southern drawl for a caller in Louisville, or a Midwestern lilt for someone in Cleveland, instead of the more generic Standard American English, colloquially known as white person voice. "We don't want to say that accents are a problem because you have one," Sanas president Marty Sarim told SFGATE. "They're only a problem because they cause bias and they cause misunderstandings." The tacit promise of Sanas seems to be that callers will be more polite -- and more amenable to being helped -- if they think the person on the other end is more like them.
San Francisco Transit Center Criticized over Restaurant's Plans for Expensive NFT-Based Private Club (sfgate.com) 166
In maybe a projection of the venture's deficits, the most common word used in interviews and marketing blurbs surrounding the decidedly exclusionary club is "community." The word, adored in the crypto world, is used relentlessly in all of Sho marketing materials, as though if said enough times this ultra-bourgeois establishment under the bright lights of Salesforce Tower's beaming helmet will somehow magically help the working man under Sauron's gaze.... Outside of the private members lounge, the restaurant will be open to the public. Sho told SFGATE over email that the number of seats and tables available to the public is not available at this time....
It's a smug celebration of the widening chasm of wealth disparity, planted in a time and a city that needs just the opposite.
Marketing materials note that paid memberships "will be minted on the Ethereum blockchain. As an NFT, the SHO Club membership will be an asset to the holder, publicly verifiable, and can later be sold or transferred on the secondary market."
So Friday SFGate.com paid another visit to "the empty husk of the building that will, if all goes smoothly, soon sell NFT memberships between $7,500 and $300,000 to join a hospitality club at a yet-to-be-constructed Japanese fine-dining restaurant in the middle of Salesforce Park." (Predicted grand opening date: September/October 2023.) The public will have allocated reservations too, [CEO Joshua] Sigel said, without revealing numbers. "Then what's the selling point for a membership?" a reporter interjected. There will be special events, a monthly membership dinner for certain tiers, and concierge service, among other benefits, Sigel said... Sigel said there's "fantastic" interest in Sho Club memberships, that they've had thousands of sign-ups on their website, and they anticipate rolling out a private NFT sale next week, followed by a public sale in mid- to late September....
Inevitably came web3 talk. Once the 3,275 NFTs memberships are sold, that's it, no more. If you want to become a member after that, you'll have to obtain a Sho Group NFT on OpenSea, a secondary market for NFTs.... Sho Group will get a 10% kickback on any secondary market sales of NFTs. A reporter astutely asked how the restaurant will keep tabs on who its new members are, once the NFTs start exchanging hands. In other words: What happens when a genuine piece of s — t snags a secondary market membership? Sigel assured us the restaurant will have a terms and conditions agreement to deal with unruly forces....
Someone abruptly asked Sigel if he'll be helping the homeless, a non sequitur of epic proportions that does, in fairness, loom over everything related to this fancy restaurant located in an ostensibly public park. "Great question," he started, announcing that in the next few weeks, his group will be rolling out a foundation of some kind. "For those who know Sho and I well, giving back and supporting the community is a very big thing for us. You specifically asked about the homeless — I have a family member who's homeless. It's near and dear to my heart, in terms of serving not only the unhoused, but also those who are in need of food."
Europe Is Seriously Considering a Major Investment In Space-Based Solar Power (arstechnica.com) 166
In concept, space-based solar power is fairly straightforward. Satellites orbiting well above Earth's atmosphere collect solar energy and convert it into current; this energy is then beamed back to Earth via microwaves, where they are captured by photovoltaic cells or antennas and converted into electricity for residential or industrial use. The primary benefits of gathering solar power from space, rather than on the ground, is that there is no night or clouds to interfere with collection; and the solar incidence is much higher than at the northern latitudes of the European continent.
The two consulting reports discuss development of the technologies and funding needed to start to bring a space-based power system online. Europe presently consumes about 3,000 TWh of electricity on an annual basis, and the reports describe massive facilities in geostationary orbit that could meet about one-quarter to one-third of that demand. Development and deployment of these systems would cost hundreds of billions of euros. Why so much? Because facilitating space-based solar power would require a constellation of dozens of huge, sunlight-gathering satellites located 36,000 km from Earth. Each of these satellites would have a mass 10 times larger, or more, than that of the International Space Station, which is 450 metric tons and required more than a decade to assemble in low Earth orbit. Launching the components of these satellites would ultimately require hundreds or, more likely, thousands of launches by heavy lift rockets. "Using projected near-term space lift capability, such as SpaceX's Starship, and current launch constraints, delivering one satellite into orbit would take between 4 and 6 years," a report by British firm Frazer-Nash states. "Providing the number of satellites to satisfy the maximum contribution that SBSP could make to the energy mix in 2050 would require a 200-fold increase over current space-lift capacity." Critics of the concept include Elon Musk and physicist Casey Handmer, among others, which take issue with the poor photon to electron to photon conversion efficiency and prohibitively expensive transmission losses, thermal losses, and logistics costs.
