IT executives see the talent shortage as the most significant adoption barrier to 64% of emerging technologies, according to a new Gartner survey. From a report: Across compute infrastructure and platform services, network, security, digital workplace, IT automation, and storage and database, respondents cited a lack of qualified candidates as a leading factor impeding tech deployment at their companies. "The ongoing push toward remote work and the acceleration of hiring plans in 2021 has exacerbated IT talent scarcity, especially for sourcing skills that enable cloud and edge, automation, and continuous delivery," Gartner research VP Yinuo Geng said in a press release.

"As one example, of all the IT automation technologies profiled in the survey, only 20% of them have moved ahead in the adoption cycle since 2020. The issue of talent is to blame here." The talent gaps are particularly acute for IT automation and digital workplace solutions, according to the executives surveyed -- a reflection of the demand for these technologies. According to McKinsey, nearly half of executives say their embrace of automation has accelerated, while digital and technology adoption is taking place about 25 times faster than before the pandemic. For example, Brain Corp reported that the use of robots to clean retail stores in the U.S. rose 24% in Q2 2020 year-over-year, and IBM has seen a surge in new users of its AI-driven customer service platform Watson Assistant.

A crop of companies want to make sperm-freezing a routine procedure for young men, as employers start to offer it as a benefit. From a report: For decades, the conversation about waning fertility has been focused largely on women. Think of Marisa Tomei stomping on the floorboards of a front porch to emulate her biological clock ticking in "My Cousin Vinny." More employers cover the cost of cryogenic egg freezing as a workplace benefit. Recently, a small group of biotech startups have hatched, dedicated to what they say is an underserved market: male fertility. Armed with recent scientific research suggesting that the quality of sperm is declining in the West, the companies are trying to make sperm-freezing a routine procedure for young, healthy men, one covered by health insurance and free of stigma.

"My fundamental belief is that if the product is affordable, this should be a no-brainer for every man," says Khaled Kteily, the 32-year-old founder of Legacy, one of the companies that Mr. Alam used to freeze his sperm. "I believe that in the future," he adds, "this will be something that parents will buy for their kids as a not-so-subtle gift." The push to make a case for its business is starting to catch on. The company recently struck a deal to eventually provide free sperm testing and storage to all active duty service members in the U.S. military, starting with the Navy SEALs, of which there are about 1,200 a year, and expanding next to all special operations forces. The Navy didn't respond to a request for comment. Soldiers regularly experience risky situations and time away from their partners, says Ellen Gustafson, a Navy wife and co-founder of the Military Family Coalition, a nonprofit that advocates for coverage of fertility medicine for members of the armed forces.

India has approved a new COVID vaccine that uses circular strands of DNA to prime the immune system against the virus SARS-CoV-2. Researchers have welcomed news of the first DNA vaccine for people to receive approval anywhere in the world, and say many other DNA vaccines may soon be hot on its heels. From a report: ZyCoV-D, which is administered into the skin without an injection, has been found to be 67% protective against symptomatic COVID-19 in clinical trials, and will likely start to be administered in India this month. Although the efficacy is not particularly high compared to that of many other COVID-19 vaccines, the fact that it is a DNA vaccine is significant, say researchers. It is proof of the principle that DNA vaccines work and can help in controlling the pandemic, says Peter Richmond, a paediatric immunologist at the University of Western Australia in Perth. "This is a really important step forward in the fight to defeat COVID-19 globally, because it demonstrates that we have another class of vaccines that we can use."

Close to a dozen DNA vaccines against COVID-19 are in clinical trials globally, and at least as many again are in earlier stages of development. DNA vaccines are also being developed for many other diseases. "If DNA vaccines prove to be successful, this is really the future of vaccinology" because they are easy to manufacture, says Shahid Jameel, a virologist at Ashoka University in Sonipat, India. The urgency of combating COVID-19 has fast-tracked the development of vaccines that use genetic technology, such as messenger RNA and DNA vaccines, says David Weiner, director of the Vaccine & Immunotherapy Center at the Wistar Institute in Philadelphia, Pennsylvania. RNA vaccines were quicker to show strong immune responses in clinical trials; they have now been delivered to hundreds of millions of people around the world. But DNA vaccines have a number of benefits, because they are easy to produce and the finished products are more stable than mRNA vaccines, which typically require storage at very low temperatures.

Docker will restrict use of the free version of its Docker Desktop utility to individuals or small businesses, and has introduced a new more expensive subscription, as it searches for a sustainable business model. The Register reports: The company has renamed its Free plan to "Personal" and now requires that businesses with 250 or more employees, or higher than $10m in annual revenue, must use a paid subscription if they require Docker Desktop. There are no changes to the command-line Docker Engine. The $5/month Pro and $7/month Teams subscriptions continue as before, but a new $21/month Business subscription adds features including centralized management, single sign-on, and enhanced security.

The Docker platform has a number of components, of which Docker Desktop is just one part. Docker images define the contents of containers. Docker containers are runnable instances of images. The Docker daemon is a background application that manages and runs Docker images and containers. The Docker client is a command-line utility that calls the API of the Docker daemon. Docker registries contain images, and the Docker Hub is a widely used public registry. Much of Docker (but not Desktop) is open source under the Apache v2 license. Docker Desktop is a GUI tool for managing various Docker components and functions, including containers, images, volumes (storage attached to containers), local Kubernetes, development environments within containers, and more. Whereas most Docker components are available for Windows, Mac and Linux, and despite the fact that most Docker containers run on Linux, Desktop is only available for Windows and Mac. Docker CEO Scott Johnston says the changes will help the company address security challenges with the software supply chain. It'll also help create a viable business model.

"We continue to see growth in the developer market. The latest stat we have is that by 2030 there's going to be 45 million global developers, up from 18-some million today... that requires us to have a business that is sustainably scalable," Johnston told The Register.

Earlier this month Jeff Bezos' Blue Origin sued NASA over a moon lander contract awarded to SpaceX.

Now Mashable reports that "America's next trip to the moon may suddenly be delayed a bit thanks to...PDFs?" A U.S. federal judge has granted the Department of Justice a week-long extension in its lawsuit with Jeff Bezos' space company Blue Origin. The reason? Large PDF files...

According to the DOJ, there is more than 7 GB of data related to the case. However, the U.S. Court of Federal Claims' online system allows for only files of up to 50 MB in size to be uploaded. This all amounts to "several hundred" PDFs, including other file formats that would be converted to PDFs. The DOJ says it also sought to convert multiple separate documents into individual PDF batches but explained that those larger files could cause the upload system to crash. "We have tried several different ways to create 50-megabyte files for more efficient filing, all without success thus far," the DOJ said.

Instead of using the online file system, the U.S. government will transfer the documents for the case to DVDs.
Futurism reports the situation was exacerbated "because the agency staff that could have fixed the issue were at the 36th Annual Space Symposium last week."

On Twitter, space reporter Joey Roullete notes the judge's ruling means an additional one-week stay before the awarding of SpaceX's contract..

Or, as Mashable puts it, "Space exploration is currently on hold thanks to a lawsuit and a slew of pesky PDF files."

CNET reports: A fossil discovered during a police raid in Brazil has turned out to be one of the best-preserved flying reptiles found yet, researchers say.

The remains belong to a tapejarid, a toothless pterosaur from the early Cretaceous period known for its huge cranial crest composed partly of bone and partly of soft tissue. Skulls and partial skeletons of Brazilian tapejarids have turned up before, but this fossil was found with more than 90% of its skeleton intact, along with some soft tissue in place around the bones.

"This fossil is special because it is the most complete pterosaur from Brazil and it brings new information about the anatomy and ecology of this animal," says Victor Beccari, co-author of a study on the find published Wednesday in the open-access journal PLOS One.

Brazilian federal police found the tapejarid fossil while investigating an illegal fossil trade operation in 2013. They recovered 3,000 specimens kept in storage units in the states of São Paulo, Minas Gerais and Rio de Janeiro and transferred them to the Geosciences Institute of the University of São Paulo for study. Since 1942, Brazilian law has categorized fossils as state property, as they're considered part of the country's geological heritage and forbidden from being sold commercially.
The tapejarid had a wingspan of more than 8 feet (2.5 meters) and stood 3.2 feet (1 meter) tall. Its head crest accounted for 40% of its height.

Tesla wants to sell electricity directly to customers in Texas, according to an application filed by the company this month with the Public Utility Commission there. From a report: The application follows the start of a big battery build out by Tesla in Angleton, Texas (near Houston), where it aims to connect a 100 megawatt energy storage system to the grid. Texas Monthly first reported on the application, submitted by a wholly owned subsidiary of Tesla called Tesla Energy Ventures. Tesla has also built several utility-scale energy storage systems around the world, including one east of Los Angeles, another underway in Monterey, California, and two in Australia -- one in Geelong, Victoria, and another in Adelaide, South Australia.

An anonymous reader quotes a report from Bloomberg: Reinsurance giant Swiss Re announced Wednesday that it had signed the world's first long-term agreement to take carbon directly out of the air. The contract with Climeworks AG, one of the world's leading direct air-capture startups, will net the climate technology company $10 million over 10 years. Mischa Repmann, a senior environmental management specialist with Swiss Re, said the deal would not only help his company reach its goal of becoming carbon neutral by 2030, it could inspire other business considering the use of carbon capture technology. "It's a call for action, and we're hoping that others will follow," he said.

Climeworks, a Switzerland-based company, is set to open a plant in Iceland in September that will filter CO from ambient air using geothermal energy. The captured CO will then be dissolved in water and pumped deep underground for permanent storage in nearby rock layers. While underground, the gas reacts naturally with its surroundings to form rock, preventing the carbon from reentering the atmosphere. The company says the facility will have the capacity to capture and store 4,000 tons of CO per year. [...] Swiss Re and Climeworks didn't specify how much carbon would be removed in fulfillment of their contract and were vague about the cost, saying only it would be several hundred dollars per ton. Climeworks says the average price will decline as its operations grow, and may be as low as $200 a ton by 2030.

Samsung smartphone owners are facing a looming deadline to rescue their photos from Samsung Cloud or risk losing backed up images. From a report: Samsung is removing the option to back up your photo gallery to Samsung Cloud, presumably in a bid to cut storage costs. Samsung Cloud will still continue to back up data such as contacts, calendar entries and notes, but photos and videos are no longer part of the package. Samsung has instead been encouraging customers to back up their photos using Microsoft's OneDrive service, but the deadline is looming for the Samsung Cloud service to be cut off, with customers warned they could lose photos if they don't have copies of them stored locally. Confusingly, Samsung has split customers into two groups, each with different cut-off deadlines. It's not easy to work out which group you're in, so it's probably safest to assume you're in Group 1, which has the earliest set of cut-off deadlines.

Scientists in Germany have developed what they say is the smallest microsupercapacitor in existence. It's smaller than a speck of dust, safe for use in the human body, and can deliver similar voltage to a AAA battery. Prior to this breakthrough, the smallest "biosupercapacitors" developed to date were 3mm^3. New Atlas reports: The construction starts with a stack of polymeric layers that are sandwiched together with a light-sensitive photo-resist material that acts as the current collector, a separator membrane, and electrodes made from an electrically conductive biocompatible polymer called PEDOT:PSS. This stack is placed on a wafer-thin surface that is subjected to high mechanical tension, which causes the various layers to detach in a highly controlled fashion and fold up origami-style into a nano-biosupercapacitor with a volume 0.001 mm^3, occupying less space than a grain of dust. These tubular biosupercapacitors are therefore 3,000 times smaller than those developed previously, but with a voltage roughly the same as an AAA battery (albeit with far lower actual current flow).

These tiny devices were then placed in saline, blood plasma and blood, where they demonstrated an ability to successfully store energy. The biosupercapacitor proved particularly effective in blood, where it retained up to 70 percent of its capacity after 16 hours of operation. Another reason blood may be a suitable home for the team's biosupercapacitor is that the device works with inherent redox enzymatic reactions and living cells in the solution to supercharge its own charge storage reactions, boosting its performance by 40 percent. The team also subjected the device to the forces it might experience in blood vessels where flow and pressure fluctuate, by placing them in microfluidic channels, kind of like wind-tunnel testing for aerodynamics, where it stood up well. They also used three of the devices chained together to successfully power a tiny pH sensor, which could be placed in the blood vessels to measure pH and detect abnormalities that could be indicative of disease, such as a tumor growth. The findings have been published in the journal Nature Communications.

Playdate, the one-bit gaming system with an analog crank, will be relatively easy to fix if you ever need to replace its battery or buttons. Ars Technica reports the findings from iFixit's teardown: The most interesting findings: The Playdate's signature crank uses a Hall effect sensor rather than a spring or another kind of wear-out-able physical mechanism, so it shouldn't suffer from drift over time like some console controller joysticks do. And while there is a warranty sticker inside the Playdate, it specifically says that you'll void the system's warranty if you break anything inside it, not that you'll void it just by taking the system apart. This strikes a good balance between "don't come in here if you don't know what you're doing" and "we trust you to make your own repairs if you need to."

The teardown also gives us a few specifics on the Playdate's intentionally low-powered hardware, which includes a 216MHz ARM Cortex M7 processor, 128 megabits (or 16MB) of RAM, and 4GB of eMMC storage. The one major complaint iFixit had is that the LCD screen appears to be glued to the front of the Playdate -- replacing the screen will probably necessitate replacing the entire rest of the casing as well. But since the front of the Playdate is simple yellow plastic rather than metal and glass, this part shouldn't cost as much as it does when your phone's screen breaks.

In a 2015 video, PCMag's lead mobile analyst Sascha Segan showed off "One of the coolest phones at this year's CES."

He's now written an article titled "How I Got Suckered by an (Alleged) $10M Phone Scam. The biggest mobile-phone mystery of the 2010s is finally coming to an ignominious end, as yesterday the U.S. attorney for Utah charged Chad Sayers, founder of entirely notional mobile phone firm Saygus, with conducting a $10 million fraud scheme. Saygus "had" a series of "phones" from 2009-2016 that existed as prototypes that the company took on trade shows and to press tours. There was never any real evidence of production runs. The U.S. Attorney now claims Sayers and associated took $10 million in investor money and lived on it without ever really planning to release a product. (I learned this via David Ruddock....)

The phone kept just...not happening. Sayers' genius was that he produced just enough prototypes to show off and kept them in a constant state of pre-sale... "DEFENDANT failed to disclose that device certification with Verizon expired in 2013 and was never renewed," the Department of Justice notes. A new version of the phone then popped up again in 2015, this one supposedly covered in Kevlar with 320GB of storage. Sayers flogged that prototype until early 2016, at which point he said it was coming "next month."

The Department of Justice says: "Between April 7, 2015 and January 10, 2017, DEFENDANT made at least 26 public statements on Twitter that its phone would be shipping 'this month,' 'this week,' or was otherwise launching, when in fact, it has never launched...."

Sayers kept going on press tours and buying expensive trade-show booths with prototypes of phones that would never hit the market, drumming up enough gullible mainstream press coverage (myself included) to presumably attract a continual stream of investors with his claim of being the next big thing.

"Hackers have drained Japanese cryptocurrency exchange Liquid of $97 million worth of Ethereum and other digital coins," reports Forbes: The company, in a tweet posted late Thursday, announced the compromise and said it is moving assets that were not affected into more secure "cold wallet" storage. The company has also suspended deposits and withdrawals... Liquid did not put a dollar figure on the amount, but blockchain analytics company Elliptic said its analysis estimates the losses at about $97 million...

Of that, $45 million were in Ethereum tokens, which are being converted into Ether, preventing the hacker from having those assets frozen. Other cryptos taken in the heist include Bitcoin, XRP, and stablecoins.

An explanation for Apple's controversial decision to begin scanning iPhones for CSAM has been found in a 2020 statement by Apple's anti-fraud chief. Eric Friedman stated, in so many words, that "we are the greatest platform for distributing child porn." The revelation does, however, raise the question: How could Apple have known this if it wasn't scanning iCloud accounts...? 9to5Mac reports: The iMessage thread was spotted by the Verge as it works its way through the internal emails, messages, and other materials handed over by Apple as part of the discovery process in the Epic Games lawsuit. Ironically, Friedman actually suggests that Facebook does a better job of detecting it than Apple did: "The spotlight at Facebook etc. is all on trust and safety (fake accounts, etc). In privacy, they suck. Our priorities are the inverse. Which is why we are the greatest platform for distributing child porn, etc."

A fellow exec queries this, asking whether it can really be true: "Really? I mean, is there a lot of this in our ecosystem? I thought there were even more opportunities for bad actors on other file sharing systems." Friedman responds with the single word, "Yes." The document is unsurprisingly labeled "Highly confidential -- attorneys' eyes only."

The stunning revelation may well be explained by the fact that iCloud photo storage is on by default, even if it's just the paltry 5GB the company gives everyone as standard. This means the service may be the most-used cloud service for photos -- in contrast to competing ones where users have to opt in. Apple has said that it has been looking at the CSAM problem for some time, and was trying to figure out a privacy-protecting way to detect it. It may well be this specific conversation that led the company to prioritize these efforts.

An anonymous reader writes: Apple's NeuralHash algorithm (PDF) -- the one it's using for client-side scanning on the iPhone -- has been reverse-engineered.

Turns out it was already in iOS 14.3, and someone noticed:

Early tests show that it can tolerate image resizing and compression, but not cropping or rotations. We also have the first collision: two images that hash to the same value. The next step is to generate innocuous images that NeuralHash classifies as prohibited content.

This was a bad idea from the start, and Apple never seemed to consider the adversarial context of the system as a whole, and not just the cryptography.

Google's next midrange smartphone is the Pixel 5a, featuring a slightly bigger display than last year's Pixel 4a, a considerably larger battery and IP67 water and dust resistance. It's priced at $449, which is $100 more than the Pixel 4a, and is expected to be the last Google phone to include a charger in the box (sorry Pixel 6 fans). Ars Technica reports: Part of the reason for the price increase is that the Pixel 5a is a bigger phone, with a 6.34-inch display and 73.7 mm width compared to the Pixel 4a's 5.8-inch display and 69.4 mm width. Another big change is the addition of IP67 dust and water resistance, which means the phone should survive submersion in 3 feet of water (1 meter) for 30 minutes. As with the Pixel 5, the Pixel 5a's body is metal coated in plastic instead of the pure plastic body of the Pixel 4a. We didn't see the appeal of this construction in the Pixel 5, but the new phone is presumably stronger now.

As usual, we're getting a no-frills design that takes care of the basics. On the front, there's a slim-bezel OLED display and a hole-punch camera in the top right, while there are two cameras (main and wide-angle) and a capacitive fingerprint reader on the back. Specs include a Snapdragon 765G (that's a 7 nm chip with two Cortex A76 cores and six Cortex A55 cores), 6GB of RAM, 128GB of storage, and the biggest battery of any Pixel: 4680 mAh. The main camera is 12.2 MP and looks like the same Sony IMX363 sensor that Google has used for the past four years. There's a 16 MP wide-angle and an 8 MP front camera. Oh yeah, the headphone jack is sticking around for at least one more year. If there's a disappointment with the Pixel 5a, it's the 60 Hz display, which is looking pretty slow in a world where 90 Hz and 120 Hz are often the norm. Another important note is that the Pixel 5a will get three years of major updates and three years of security updates. It's currently available for preorder now and starts shipping on August 26.

An anonymous reader quotes a report from Interesting Engineering: The Manatee Energy Storage Center -- the world's largest solar-powered battery storage facility -- is now 75% finished with 100 of 132 total containers already installed, reveals a press release from Florida Power and Light Company (FPL). The battery is housed in Manatee County as the name indicates and is expected to be fully operational by the end of the year. When completed, the system will have a 409-MW capacity with the ability to deliver 900 MWh of energy. This is enough electricity to power 329,000 homes for more than two hours.

The battery will serve to replace FPL's coal plants. The battery will store energy in order to bring electricity to homes even when the sun's not shining (at night and on cloudy days) meaning other more polluting power sources will not be required. Although customers are bound to see some financial benefits the main gains will be environmental. According to FPL, each battery module is capable of storing an amount of solar energy equivalent to roughly 2,000 iPhone batteries. The complete battery system will be equivalent to 100 million iPhone batteries and the energy storage containers will be organized across a 40-acre plot of land (the equivalent of 30 football fields). The battery will have a lifespan of 40 years.

Ars Technica reports on a paper investigating how much each power plant contributes to global emissions, using data from 2018. "The study finds that many countries have many power plants that emit carbon dioxide at rates well above either the national or global average.

"Shutting down the worst 5 percent of this list would immediately wipe out about 75 percent of the carbon emissions produced by electricity generation." It should surprise nobody that all the worst offenders are coal plants. But the distribution of the highest polluting plants might include a bit of the unexpected.

For example, despite its reputation as the home of coal, China only has a single plant in the top-10 worst (bottom-10?). In contrast, South Korea has three on the list, and India has two. In general, China doesn't have many plants that stand out as exceptionally bad, in part because so many of its plants were built around the same time, during a giant boom in industrialization. As such, there's not much variance from plant to plant when it comes to efficiency. In contrast, countries like Germany, Indonesia, Russia, and the US all see a lot of variance, so they're likely to have some highly inefficient plants that are outliers.

Put a different way, the authors looked at how much of a country's pollution was produced by the worst 5 percent when all of the country's power plants were ranked by carbon emissions. In China, the worst 5 percent accounted for roughly a quarter of the country's total emissions. In the US, the worst 5 percent of plants produced about 75 percent of the power sector's carbon emissions. South Korea had similar numbers, while Australia, Germany, and Japan all saw their worst 5 percent of plants account for roughly 90 percent of the carbon emissions from their power sector. When it comes to carbon emissions, the worst 5 percent of power plants account for 73 percent of the total power sector emissions globally. That 5 percent also produces over 14 times as much carbon pollution as it would if the plants were merely average...

Simply boosting each plant's efficiency to the average for the country would drop power sector emissions by a quarter and up to 35 percent in countries like Australia and Germany. Switching them to natural gas, which produces less carbon dioxide per amount of energy released, would drop global emissions by 30 percent, with many countries (including the US) seeing drops of over 40 percent. Again, because China doesn't see a lot of variance among its plants, these switches would have less of an impact, being in the area of 10 percent drops in emissions. But the big winner is carbon capture and storage. Outfitting the worst of the plants with a capture system that was 85 percent efficient would cut global power sector emissions in half and total global emissions by 20 percent. Countries like Australia and Germany would see their power sector emissions drop by over 75 percent.

Overall, these are massive gains, considering that it's not unreasonable to think that the modifications could be done in less than a decade. And they show the clear value of targeting the easiest wins when it comes to lowering emissions.

An anonymous reader quotes a report from Ars Technica: Most hydrogen today is made by exposing natural gas to high heat, pressure, and steam in a process that creates carbon dioxide as a byproduct. In what's called "gray" hydrogen, all that carbon dioxide is released into the atmosphere. In "blue" hydrogen, facilities capture the carbon dioxide and sell it or store it, usually deep underground. Blue hydrogen is viewed by some as a bridge fuel, a way to build the hydrogen economy while waiting for green hydrogen prices to come down. In the meantime, blue hydrogen is also supposed to pollute less than gray hydrogen, natural gas, or other carbon-intensive fuel sources. Except blue hydrogen may not be low-carbon at all, according to a new peer-reviewed study. In fact, the study says the climate may be better off if we just burned coal instead.

There are essentially two ways to make blue hydrogen, and both rely on steam reformation, the process of using high heat, pressure, and steam that cracks methane and water to produce hydrogen and carbon dioxide. For both approaches, carbon dioxide from steam reformation is captured and stored or used. The difference between the two is whether carbon dioxide is captured from the generators that power the steam-reformation and carbon-capture processes. When you add it all up, capturing carbon from all parts of the process -- steam reformation, power supply, and carbon capture -- eliminates just 3 percent of greenhouse gas emissions compared with only capturing carbon from steam reformation. The lowest-carbon blue hydrogen had emissions that were just 12 percent lower than for gray hydrogen. Blue hydrogen's Achilles' heel is the methane used to produce it. Methane is the dominant component of natural gas, and while it burns more cleanly than oil or coal, it's a potent greenhouse gas on its own. Over 20 years, one ton of the stuff warms the atmosphere 86 times more than one ton of carbon dioxide. That means leaks along the supply chain can undo a lot of methane's climate advantages.

In the new study, Robert Howarth and Mark Jacobson, the paper's authors and two well-known climate scientists, assume a leakage rate of 3.5 percent of consumption. They arrived at that number by scouring 21 studies that surveyed the emissions of gas fields, pipelines, and storage facilities using satellites or airplanes. To see how their 3.5 percent rate affected the results, Howarth and Jacobson also ran their models assuming 1.54 percent, 2.54 percent, and 4.3 percent leakage. Those rates are based on EPA estimates at the low end and, at the high end, stable carbon isotope analysis that isolated emissions from shale gas production. No matter which leakage rate they used, blue hydrogen production created more greenhouse gas equivalents than simply burning natural gas. And at the 3.5 percent leakage rate, blue hydrogen was worse for the climate than burning coal. "Combined emissions of carbon dioxide and methane are greater for gray hydrogen and for blue hydrogen (whether or not exhaust flue gases are treated for carbon capture) than for any of the fossil fuels," Howarth and Jacobson wrote. "Methane emissions are a major contributor to this, and methane emissions from both gray and blue hydrogen are larger than for any of the fossil fuels."

The Register's Richard Speed commemorates the 40th anniversary of the introduction of the IBM Model 5150: IBM was famously late to the game when the Model 5150 (or IBM PC) put in an appearance. The likes of Commodore and Apple pretty much dominated the microcomputer world as the 1970s came to a close and the 1980s began. Big Blue, on the other hand, was better known for its sober, business-orientated products and its eyewatering price tags. However, as its customers began eying Apple products, IBM lumbered toward the market, creating a working group that could dispense with the traditional epic lead-times of Big Blue and take a more agile approach. A choice made was to use off-the-shelf hardware and software and adopt an open architecture. A significant choice, as things turned out.

Intel's 8088 was selected over the competition (including IBM's own RISC processor) and famously, Microsoft was tapped to provide PC DOS as well as BASIC that was included in the ROM. So this marks the 40th anniversary of PC DOS, aka MS-DOS, too. You can find Microsoft's old MS-DOS source code here. The basic price for the 5150 was $1,565, with a fully loaded system rising to more than $3,000. Users could enjoy high resolution monochrome text via the MDA card or some low resolution graphics (and vaguely nauseating colors) through a CGA card (which could be installed simultaneously.) RAM landed in 16 or 64kB flavors and could be upgraded to 256kB while the Intel 8088 CPU chugged along at 4.77 MHz.

Storage came courtesy of up to two 5.25" floppy disks, and the ability to attach a cassette recorder -- an option swiftly stripped from later models. There was no hard disk, and adding one presented a problem for users with deep enough pockets: the motherboard and software didn't support it and the power supply was a bit weedy. IBM would resolve this as the PC evolved. Importantly, the motherboard also included slots for expansion, which eventually became known as the Industry Standard Architecture (ISA) bus as the IBM PC clone sector exploded. IBM's approach resulted in an immense market for expansion cards and third party software. While the Model 5150 "sold like hotcakes," Speed notes that it was eventually discontinued in 1987.
