Apps from Chinese developers have been gaining popularity on Indian app stores for sometime. Last year, as many as 44 of the top 100 Android apps in India were developed by Chinese firms.

But things have changed this year as local developers put on a fight. According to app analytics and marketing firm AppsFlyer, Indian apps as a whole have recaptured their original standing.

41% of top 200 apps in Indian editions of Google’s Play Store and Apple’s App Store in Q2 and Q3 this year were developed by Indian developers and local firms, up from 38% last year, the report said. Data from App Annie, another research firm, corroborates the claim.

“This uptick happened chiefly at the expense of Chinese apps, which fell from their lead position to 38% from 43% in 2018. Altogether, Chinese and Indian apps make up almost four-fifths (79%) of the list,” the report said.

The shift comes as scores of Indian firms have launched payments, gaming, news, and entertainment apps in the last year and a half, said AppsFlyer, which analyzed 6.5 billion installs in the second and third quarters of this year.

But Chinese developers are not giving up and continue to maintain an “impressive” fight in each category, the report said.

India — which is home to more than 450 million smartphone users and maintains relatively lax laws to support an open market — has naturally emerged as an attractive battleground for developers worldwide.

Many Chinese firms including Xiaomi and ByteDance count India as one of their largest markets. TikTok app has amassed over 200 million users in India, for instance. Xiaomi, which leads the Indian smartphone market, is quickly building a portfolio of services for users in India. It launched a lending app in the country earlier this month.

Gaining traction among first time internet users, most of whom have lower financial capacity, can prove challenging. Those developing travel apps had to spend about 170 Indian rupees ($2.4) for each install, for instance. Food and drink app makers spent 138 Indian rupees ($1.9) per install during the aforementioned period, while games cost 13.5 Indian rupees.

Despite the marketing spends, retention rate for these apps was 23.4% on day 1, a figure that plummeted to 2.6% by the end of the month. (This is still an improvement over retention rates of 22.8% on day 1, and 2.3% on day 30 last year.)

Modern agriculture involves fields of mind-boggling size, and spraying them efficiently is a serious operational challenge. Pyka is taking on the largely human-powered spray business with an autonomous winged craft and, crucially, regulatory approval.

Just as we’ve seen with DroneSeed, this type of flying is risky for pilots, who must fly very close to the ground and other obstacles, yet also highly susceptible to automation; That’s because it involves lots of repetitive flight patterns that must be executed perfectly, over and over.

Pyka’s approach is unlike that of many in the drone industry, which has tended to use multirotor craft for their maneuverability and easy take-off and landing. But those drones can’t carry the weight and volume of pesticides and other chemicals that (unfortunately) need to be deployed at large scales.

The craft Pyka has built is more traditional, resembling a traditional one-seater crop dusting plane but lacking the cockpit. It’s driven by a trio of propellers, and most of the interior is given over to payload (it can carry about 450 pounds) and batteries. Of course there is also a sensing suite and onboard computer to handle the immediate demands of automated flight.

Pyka can take off or land on a 150-foot stretch of flat land, so you don’t have to worry about setting up a runway and wasting energy getting to the target area. Of course, it’ll eventually need to swap out batteries, which is part of the ground crew’s responsibilities. They’ll also be designing the overall course for the craft, though the actual flight path and moment-to-moment decisions are handled by the flight computer.

All this means the plane, apparently called the Egret, can spray about a hundred acres per hour, about the same as a helicopter. But the autonomous craft provides improved precision (it flies lower) and safety (no human pulling difficult maneuvers every minute or two).

Perhaps more importantly, the feds don’t mind it. Pyka claims to be the only company in the world with a commercially approved large autonomous electric aircraft. Small ones like drones have been approved left and right, but the Egret is approaching the size of a traditional “small aircraft” like a Piper Cub.

Of course, that’s just the craft — other regulatory hurdles hinder wide deployment, like communicating with air traffic management and other craft; certification of the craft in other ways; a more robust long-range sense and avoid system, and so on. But Pyka’s Egret has already flown thousands of miles at test farms that paying for the privilege. (Pyka declined to comment on its business model, customers, or revenues.)

The company’s founding team — Michael Norcia, Chuma Ogunwole, Kyle Moore, and Nathan White — comes from a variety of well-known companies working in adjacent spaces: Cora, Kittyhawk, Joby Aviation, Google X, Waymo, and Morgan Stanley (that’s the COO).

The $11M seed round was led by Prime Movers Lab, with participation from Y Combinator, Greycroft, Data Collective, and Bold Capital Partners.

3D printing has proven itself useful in so many industries that it’s no longer necessary to show off, but some people just can’t help themselves. Case in point: this millimeter-tall rendition of Michelangelo’s famous “David” printed with copper using a newly developed technique.

The aptly named “Tiny David” was created by Exaddon, a spin-off company from another spin-off company, Cytosurge, spun off from Swiss research university ETH Zurich. It’s only a fraction of a millimeter wide and weighs two micrograms.

It was created using Exaddon’s “CERES” 3D printer, which lays down a stream of ionized liquid copper at a rate of as little as femtoliters per second, forming a rigid structure with features as small as a micrometer across. The Tiny David took about 12 hours to print, though something a little simpler in structure could probably be done much quicker.

As it is, the level of detail is pretty amazing. Although, obviously, you can’t recreate every nuance of Michelangelo’s masterpiece, even small textures like the hair and muscle tone are reproduced quite well. No finishing buff or support struts required.

Of course, we can create much smaller structures at the nanometer level with advanced lithography techniques, but that’s a complex, sensitive process that must be engineered carefully by experts. This printer can take an arbitrary 3D model and spit it out in a few hours, and at room temperature.

But the researchers do point out that there is some work involved.

“It is more than just a copy and downsized model of Michelangelo’s David,” said Exaddon’s Giorgio Ercolano in a company blog post. “Our deep understanding of the printing process has led to a new way of processing the 3D computer model of the statue and then converting it into machine code. This object has been sliced from an open-source CAD file and afterwards was sent directly to the printer. This slicing method enables an entirely new way to print designs with the CERES additive micromanufacturing system.”

Much smaller than that doesn’t work, though — Micro-David starts looking like he’s made of Play-Doh snakes. That’s fine, they’ll get there eventually.

The team published the details of their newly refined technique (it was pioneered a few years ago but is much better now) in the journal Micromachines.

Max Q is a new weekly newsletter all about space. Sign up here to receive it weekly on Sundays in your inbox.

Typically, the holiday season is a slow one in the tech industry — but space tech is different, and this past week saw a flurry of activity, including one of the most important rocket launches of the year.

Just about every significant new space company got in on the action during the past seven days, either with actual spacecraft launches, or with big announcements. And everything that went down sets up 2020 to be even crazier.

Boeing’s big year-end mission doesn’t go as planned

Boeing managed to get a crucial test launch in for its commercial crew program — which is NASA’s effort to get U.S. astronauts launching from U.S. soil once again. Boeing launched its “orbital flight test” or OFT on Friday, and the actual rocket launch part of the flight went exactly as intended.

Unfortunately, what came next didn’t match up with what was supposed to happen: The Starliner spacecraft (which wasn’t actually carrying anyone for this test) ran into an error with its onboard mission clock that led to it expending more fuel more quickly than it should have, leaving it with not enough fuel to make its planned rendezvous with the ISS.

… but at least it stuck the landing

The Starliner capsule didn’t dock with the Space Station, but it still completed a number of key objectives, like demonstrating that its docking arm extended properly. Maybe most importantly, it also landed back on Earth on time and on target, per the revised mission plan that Boeing and NASA hammered out once they determined they couldn’t reach the station as planned. In space as in startups, even failures are successes of a kind.

SpaceX launches Falcon 9 but misses the fairing catch

SpaceX’s latest launch took place on Monday, and it was a success in just about every regard — except in terms of one of its secondary missions, which was an attempt to catch the two fairing halves that together cover the payload as the rocket ascends to space. SpaceX has been trying to catch these with ships at sea equipped with large nets, and it caught one previously. It’ll keep trying, just like it did with rocket booster landings, and could save up to $6 million per launch once it gets the process right.

Europe launched a planet-watcher

The European Space Agency also launched a rocket this week — a Soyuz carrying a new satellite that will observe exoplanets (planets outside our solar system) from orbit. It’ll be able to assess their density from that vantage point, giving us valuable new info about the potential habitability of distant heavenly bodies.

Apple might enter the satellite constellation game

Apple apparently has its own team internally working on satellite communication technologies. This effort may or may not involve the iPhone-maker actually developing its own spacecraft, but it seems like the overall goal is to develop its own direct wireless communication network to work with iPhones and other Apple hardware.

Amazon is opening a dedicated HQ for its satellite business

Meanwhile, Amazon’s own satellite business is a known quantity called “Project Kuiper,” and the company is going to double down on its investment next year with a new dedicated space for Kuiper’s R&D and prototype manufacturing. Eventually, Kuiper will be a constellation of low Earth orbit satellites providing broadband to underserved and unserved areas of the globe.

Rocket Lab is already working on its third launch pad

Rocket Lab will be opening a third launch pad, the company announced, just after declaring its second in Virginia this month. The third launch site will be at the same spot as its first — on the Mahia peninsula in northern New Zealand.

Last week, Spotify sent a number of USB drives to reporters with a note: “Play me.”

It’s not uncommon for reporters to receive USB drives in the post. Companies distribute USB drives all the time, including at tech conferences, often containing promotional materials or large files, such as videos that would otherwise be difficult to get into as many hands as possible.

But anyone with basic security training under their hat — which here at TechCrunch we do — will know to never plug in a USB drive without taking some precautions first.

Concerned but undeterred, we safely examined the contents of the drive using a disposable version of Ubuntu Linux (using a live CD) on a spare computer. We examined the drive and found it was benign.

On the drive was a single audio file. “This is Alex Goldman, and you’ve just been hacked,” the file played.

The drive was just a promotion for a new Spotify podcast. Because of course it was.

Jake Williams, a former NSA hacker and founder of Rendition Infosec, called the move “amazingly tone deaf” to encourage reporters into plugging in the drives to their computers.

USB drives are not inherently malicious, but are known to be used in hacking campaigns — like power plants and nuclear enrichment plants — which are typically not connected to the internet. USB drives can harbor malware that can open and install backdoors on a victim’s computer, Williams said.

“The files on the USB itself may contain active content,” he said, which when opened can exploit a bug on an affected device.

A spokesperson for Spotify did not comment. Instead, it passed our request to Sunshine Sachs, a public relations firm that works for Spotify, which would not comment on the record beyond that “all reporters received an email stating this was on the way.”

Plugging in random USB drives is a bigger problem than you might think. Elie Bursztein, a Google security researcher, found in his own research that about half of all people will plug into their computer random USB drives.

John Deere earlier this year caused a ruckus after it distributed a promotion drive that actively hijacked the computer’s keyboard. The drive contained code which when plugged in ran a script, opened the browser and automatically typed in the company’s website. Even though the drive was not inherently malicious, the move was highly criticized, as malware often acts in an automated, scripted way.

Given the threats that USB drives can pose, Homeland Security’s cybersecurity division CISA last month updated its guidance about USB drive security. Journalists are among those who are frequent targets by some governments, including targeted cyberattacks.

Remember: Always take precautions when handling USB drives. And never plug one in unless you trust it.
