German scientists have built a high resolution microscope out of Lego parts and components salvaged from a mobile phone, according to a recent paper published in The Biophysicist. They found that children who undertook the project—including building their microscopes and conducting several at-home experiments—gained enhanced understanding of how microscopy works. It's part of an ongoing "frugal science" trend: using cheap consumer hardware and open-source software to build low-cost scientific instruments. The DIY tools are perfect for educational environments and for field use in developing countries.

"An understanding of science is crucial for decision-making and brings many benefits in everyday life, such as problem-solving and creativity," said co-author Timo Betz of the University of Göttingen. "Yet we find that many people, even politicians, feel excluded or do not have the opportunities to engage in scientific or critical thinking. We wanted to find a way to nurture natural curiosity, help people grasp fundamental principles, and see the potential of science." 

Perhaps the best known low-cost DIY instrument to date is the Foldscope, an optical microscope easily assembled out of a sheet of paper and a lens. It comes as a kit, which includes magnets so users can attach a smartphone to the Foldscope and take pictures of the magnified samples. It's robust enough to survive being dropped or getting wet, and the magnification is strong enough to view E. coli and malarial parasites in a sample.

Qualcomm's new CEO, Cristiano Amon, says the company will have no problem producing laptop chips to compete directly with Apple's M1—mainly because Qualcomm now employs some of the key minds behind Apple's highly publicized breakthrough.

Amon told Reuters in a recent interview that Qualcomm will attempt to design its own system-on-a-chip (SoC) for laptops without working with ARM, its partner in smartphone chips.

This SoC would include a 5G modem as well as a CPU. Explaining this strategy, Amon said:

BitTorrent Turns 20: The File-Sharing Revolution Revisited

Twenty years ago a then relatively unknown programmer named Bram Cohen single-handedly sparked a new file-sharing revolution. At the time, social media had yet to be invented, but BitTorrent never needed likes to go viral. The file-sharing protocol sold itself and soon conquered the Internet.

From: TF, for the latest news on copyright battles, piracy and more.

“My new app, BitTorrent, is now in working order, check it out here,” Bram Cohen wrote on a Yahoo! message board on July 2, 2001.

This was probably one of the more underwhelming software launches in history. The official website, consisting of a few lines of HTML code with black text on a white background, didn’t impress either. Nothing hinted at the powerhouse BitTorrent would soon become.

While BitTorrent lacked a fancy PR channel, its creator made up for that with coding inventiveness. Cohen previously worked for the startup behind the MojoNation peer-to-peer network. That project eventually ran out of money so the then 25-year old developer went on to focus on his own file-sharing protocol.

Cohen certainly wasn’t the only programmer in this niche. At the time, file-sharing was booming and dozens of new applications were popping up. Napster had already laid the groundwork and, with MP3s getting more popular by the day, sharing was hot.

More People, Faster Downloads

BitTorrent was different though. It clearly set itself apart from competitors by focusing on speed and decentralization. Instead of simply sharing a file with one person at a time, BitTorrent created swarms of sharers, that would see download speeds increase when more people joined.

bittorrent architecture

The decentralization aspect was pretty novel. Most file-sharing tools used a centralized infrastructure accessed through a single piece of software. BitTorrent launched as an open protocol that integrated well with the web. Perhaps too well.

Just a few months after BitTorrent was publicly released, the first ‘torrent sites‘ sprung up. These included Suprnova.org, Donkax.com, Bytemonsoon.com, and Torrentse.cx.

These sites allowed users to upload and share music, photos, software, and even movies. Offering these types of (often pirated) files to a mass audience wasn’t an option before, simply because the bandwidth and storage costs were too high.

With BitTorrent, these sites only had to host the small .torrent files, which proved to be a gamechanger.

Embracing The Web

Bram Cohen stayed far away from these controversial sites but clearly embraced the general “media sharing” functionality early on. Late 2001, Etree was announced as one of the first sites to embrace the new BitTorrent protocol.

“BitTorrent’s customer is etree. Etree is a loose-knit community of people who distribute live concert recordings online,” Cohen wrote. “Etree suffers from not having nearly as much upload offered as there is download demand, a problem BitTorrent solves.”

Today, 20 years later, Etree still offers torrent downloads for thousands of concerts even though bandwidth isn’t nearly as expensive as it once was.

Part of BitTorrent’s early success was due to the cost savings which made it possible to share large files quickly. This may sound trivial today but in the dial-up age, years before YouTube came around, it was a revolution.

Search Engines

The seamless connection between the web and BitTorrent had other advantages as well. It allowed torrent sites to create searchable indexes, which in turn could be picked up by search engines. Google, for example, a toddler itself at the time.

With help from search engines and word of mouth advertising torrent sites grew quickly. This includes The Pirate Bay, which launched in 2003 and is still around despite criminal prosecutions and two police raids.

This exponential growth of torrent sites wasn’t just limited to public indexes. Meta-search engines and smaller communities started to form as well.

These private trackers, some of which focused on tighter niches, each came with their own sets of sharing rules. The music library OiNK, for example, was once hailed as the largest music library ever, before streaming services became a thing. And after OiNK shut down, What.cd took over, until it was taken down as well.

Taming a Torrent of Traffic

Torrents were gaining traction in the early 2000s and that didn’t go unnoticed by Internet providers. At one point, BitTorrent was estimated to account for one-third of all Internet traffic worldwide.

This traffic was a heavy burden on Internet providers’ infrastructures and several large ISPs countered this by actively throttling torrent traffic. This included Comcast in the US, as well as many foreign ISPs.

The throttling activity caused a media storm that, according to some, marked the start of the public net neutrality debate.

Researchers chimed in with tests that allowed people to see if their ISPs were restricting traffic, outing the worst offenders. Meanwhile, the BitTorrent protocol was updated to make throttling harder with protocol header encryption, while uTP support was added to decrease the load on ISPs.

BitTorrent Inc.

The protocol updates were monitored by Cohen who by then had successfully transformed his protocol into a tech startup, BitTorrent Inc, which raised millions of dollars in venture capital.

BitTorrent Inc had nothing to do with pirate sites and focused on developing BitTorrent while helping artists and other rightsholders to share content.

In 2007 the company launched its own video store, the ‘Torrent Entertainment Network,’ which partnered with major Hollywood studios such as Warner Bros. The video store never became profitable and eventually closed its doors a year later.

In the years that followed BitTorrent Inc focused on helping artists to promote their content, including via BitTorrent Now which is still around, but those weren’t major breakthroughs.

One of BitTorrent’s best decisions was made in 2006 when it bought the uTorrent client from the Swedish developer Ludvig Strigeus. Today, uTorrent is still the dominant torrent client, while Strigeus went on to make Spotify a success.

BitTorrent Breakup

Some early investors had hoped to cash in big when they put their money into BitTorrent, but the company never really broke through. Revenue from uTorrent helped to keep the company afloat but most new torrent projects were eventually disbanded.

Bram Cohen wasn’t always happy with the company either. In 2018, BitTorrent Inc. was bought by the TRON Foundation and a month later BitTorrent’s inventor announced his departure.

In recent years BitTorrent has had a heavy ‘crypto’ focus. Under TRON’s wings the BitTorrent token (BTT) was launched, which can be used by torrent users to pay for faster download speeds, or earn while seeding.

Aside from designing complex puzzles, Cohen himself has also developed an interest in cryptocurrency. BitTorrent’s inventor is one of the driving forces behind the ‘greener’ Chia coin, which launched earlier last May.

BitTorrent ≠ Piracy

In the media, and the public eye, torrents are frequently associated with piracy. It’s worth emphasizing that it is much more than that.

bittorrent not a crime

Over the years many reputable companies and organizations, including Twitter, Google, Facebook, NASA, and others, have used BitTorrent technology to their advantage. Simply because it’s great at cheaply and efficiently transferring files.

Many software projects, including iconic Linux distributions, still offer BitTorrent downloads too. Fairly recently, OpenStreetMap joined in by offering torrent feeds to download updated versions of its maps.

As bandwidth costs dropped over the years, BitTorrent has lost some of its edge, but it continues to be a superior technology and a source of innovation. Whatever the future holds, it has certainly cemented its place in the Internet’s history books.

That brings us back to Cohen’s announcement on July 2, 2001. At the time, that post only triggered one response, which was a question. While Bram never replied, we assume that it has since been answered.

“What’s BitTorrent, Bram?…”

New, deadly bacteria may be lurking in US; CDC warns of three puzzling cases

This isn’t the first time the deadly bacteria has surfaced in the US unexpectedly.

A deadly soil bacterium common in tropical and subtropical climates has mysteriously infected three people in three different US states, killing at least one, according to a health alert from the Centers for Disease Control and Prevention.

While US cases of the infection periodically pop up in travelers, none of the three infected people have recent travel history that could easily explain how they picked up the dangerous germ. The bacteria, Burkholderia pseudomallei, usually infects by direct contact with an environmental source, i.e. contaminated soil or water. It most often attacks through breaks in the skin. It very rarely jumps from human to human. Yet genetic analyses of the bacterial strains in the latest US cases indicate that the three, geographically-separated infections are related.

The curious cluster of cases suggests there was a common source of the bacteria. Investigators speculate that a yet-unidentified imported product or animal could be a common source. But it also raises the specter that B. pseudomallei is no longer a mere interloper in the US, rather it may have become a permanent, low-key resident.

Despite $2.1M ruling, RomUniverse owner considers bringing back ROM site

Nintendo seeks permanent injunction after Storman fails to make $50/month payment.

RomUniverse has been down for months, but owner Matt Storman may be considering bringing it back despite a court judgment.

Enlarge / RomUniverse has been down for months, but owner Matt Storman may be considering bringing it back despite a court judgment.

In May, a US District Court ordered former RomUniverse.com owner Matthew Storman to pay $2.1 million in damages to Nintendo for copyright and trademark infringement. Now, Nintendo is seeking an additional permanent injunction against Storman, who it says is considering bringing the ROM site back without "Nintendo content" and who has failed to make a $50-per-month payment toward those damages.

Storman—who said in court documents that his post-RomUniverse income was derived primarily from "unemployment and food stamps"—seems unlikely to ever pay even a small chunk of the $2.1 million judgment against him. Paying a token $50 a month, an amount Nintendo says Storman "proposed and agreed to," would mean that fully covering the damages would take Storman 3,500 years, and that's without accounting for interest.

Still, Nintendo is using the damages to its advantage, arguing that Storman's failure to make his first $50 monthly payment "demonstrates that Nintendo has no adequate remedy at law for Defendant’s past or future infringement and underscores the need for a permanent injunction."

OnePlus now has one of the best Android update schedules

Flagship OnePlus phones get three major OS updates, four years of security updates.

OnePlus is finally taking care of what used to be a weak point of its phones: their update schedules. The company announced on Friday that the OnePlus 8 series (T, R, regular, and Pro) and all newer flagships will get three major Android OS updates and four years of security updates. We're still waiting for details from OnePlus, but on the surface, this commitment matches Samsung's update plan, putting OnePlus in a tie for the best Android support timeline. Google, the company that makes Android, is now in third.

OnePlus is in the midst of a big upheaval, and the future of the company is not entirely clear. For years, OnePlus offered flagship-style smartphones at surprisingly low prices, peaking with the $670 OnePlus 7 Pro in 2019. Since then, co-founder Carl Pei left the company in October 2020, which kicked off what seems like a significant shift in strategy. 2021's OnePlus 9 Pro was $969, basically the same price as a comparable Samsung phone. In January 2021, OnePlus said it was merging "some R&D capabilities" with Chinese parent company Oppo, and in June 2021, the two companies announced that they were merging completely.

OnePlus says the new, longer support time is the result of the company merging the development of OnePlus' Android skin, Oxygen OS, with Oppo's Android skin, Color OS. The two skins are generally targeted at different markets, but it doesn't sound like the UIs will be merged. OnePlus says, "This is a change that you will likely not even notice since it’s happening behind the scenes."
