Atlanta’-based Speedscale now has $2.2 million more to grow its API test automation business



It only took a few weeks after its Y Combinator demo day debut for the Atlanta-based API test automation company Speedscale to raise its first $2.2 million.

Founded by longtime developers and Georgia Institute of Technology alumni, Ken Ahrens, Matthew LeRay and Nate Lee had known each other for roughly twenty years before making the jump to working together.

A circuitous path of interconnecting programming jobs in the devops and monitoring space led the three men to realize that there was an opportunity to address one of the main struggles new programmers now face — making sure that updates to api integrations in a containerized programming world don’t wind up breaking apps or services.

“We were helping to solve incident outages and incidents that would cause downtime,” said Lee. “It’s hard to ensure the quality between all of these connection points [between applications]. And these connection points are growing as people add apis and containers. We said, ‘How about we solve this space? How could we preempt all of this and ensure maintaining release velocity with scalable automation?’”

Typically companies release new updates to code in a phased approach or in a test environment to ensure that they’re not going to break anything. Speedscale proposes test automation using real traffic so that developers can accelerate the release time.

“They want to change very frequently,” said Ahrens, speaking about the development life cycle. “Most of the changes are great, but every once in a while they make a change and break part of the system. The state of the art is to wait for it to be broken and get someone to fix it quickly.”

The pitch SpeedScale makes to developers is that its service can give coders the ability to see the problems before the release. They automate the creation of the staging environment, automation suite and orchestration to create that environment.

“One of the big things for me was when I saw the rise of Kubernetes was what’s really happening is that engineering leaders have been able to give more autonomy to developers, but no one has come up with a great way to validate and I really think that Speedscale can solve that problem.”

The Atlanta-based company, which only just graduated from Y Combinator a few months ago, is currently in a closed alpha with select pilot partners, according to LeRay. And the nine month-old company has raised $2.2 million from investors including Sierra Ventures from the Bay Area and Atlanta’s own Tech Square Ventures to grow the business.

“Apis are a huge market,” Ahrens said of the potential opportunity for the company. “there’s 11 million developers who develop against apis… We think the addressable market for us is in the billions.”

NASA’s robot just landed on Bennu after 2 years — but its mission has only just begun



Relief showed clearly on the faces of the team of NASA scientists and engineers as they were told: “Touchdown is complete”. Then applause a few seconds later for “back away burn complete”. The most hazardous part of the mission was over – and seemingly successful, although we will have to wait for a few more days to hear the scale of the success.

OSIRIS-REx (for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer)) was launched in September 2016, arriving at its target asteroid 101955 Bennu in December 2018. The purpose of the mission was to characterize the asteroid, then bring some of it back for study on Earth.

The spacecraft spent two years circling Bennu, making detailed maps of its surface, learning as much as possible about the asteroid before the next phase of the mission: looking for somewhere safe to land. Or, rather, not to land, but to make a very rapid “touch-and-go” visit to the surface – where it would collect fragments of material to return to Earth. It was completion of the touch-and-go manoeuvre that prompted the clapping and cheering in mission control.

Why Bennu? And why the relief? After all, this is not the first asteroid that a spacecraft has visited – and it is not the first small body that has been landed on. That record is held by the NEAR spacecraft that made a controlled crash-landing on Asteroid 433 Eros in 2001. And I still remember the emotion in the control room when Philae landed on comet 67P/Churyumov-Gerasimenko in 2014.

The relief was because Bennu is small – only about 500 meters across – a fact that was known when it was selected as a target. But it is oddly shaped and active – two things that were not known. It looks a bit like an old-fashioned spinning top, or a rough diamond, pointed at the top and bottom and fatter in the middle. Because it is so small it was assumed that Bennu would be quiescent – it wouldn’t, for instance, be behaving like a comet and ejecting bursts of gas and rocks.

But because nothing in the solar system is simple, when OSIRIS-Rex got close to Bennu, it found that the asteroid was throwing small amounts of material from its surface. The particles were less than a centimeter across, and most of them landed back on the asteroid – generally closer to the equator than the poles, which changed its shape over time.

One of the consequences of the activity – explained by changes in temperature fracturing larger boulders and breaking up the rocks – is that the surface of Bennu is completely covered in rubble, much more than had been expected. This made selecting a site for sample collection more difficult.

Secrets of the solar system

Bennu is a Near Earth Asteroid – it has a one-in-2700 chance of colliding with the Earth in about 170 years’ time. It is also believed to be rich in the type of organic compounds that might have seeded the Earth to enable life to arise.

Another surprising find that came from the mapping campaign was that Bennu was not only rich in clay minerals, but that veins of carbonate were present. Clay and carbonates require water – lots of it – so these minerals must have formed when Bennu was part of a larger asteroid. There is no running water there now – but there might be small pockets of ice below the surface. While this ice will not be collected by OSIRIS_Rex, the effects of water should be seen in the material it’s gathered.

Studying these materials will help us understand the primitive dust from which the solar system grew, and the range of organic compounds present. It will also tell us the physical properties of something that might hit the Earth, potentially helping us stop it.

It was always going to be tricky to collect material from the surface – any attempt to land would be unlikely to succeed, because the low gravitational pull of Bennu would not grab onto a lander and hold it in place. A lander would bounce off, back into space. This is why NASA used the touch-and-go approach – the spacecraft approached the asteroid very slowly, hovering only a meter or so from its surface, while an arm was extended to touch the surface to collect a sample.

It did this by blowing a jet of nitrogen gas onto the surface, which was sufficiently powerful to throw material into the collection canister. The slow approach to the surface took several nail-biting hours, while the collection operation took a matter of seconds. Collection over, and the spacecraft backed away – hence the relief at mission control at the “back away, burn complete” message, showing that OSIRIS-Rex was moving away from the surface.

We don’t yet know how much material was blown into the canister – and we won’t know until it arrives back on Earth in September 2023. It might be 60 grams – which is the target – or it might be as much as a kilogram. An attempt will be made later this week to see how the moment of inertia of the spacecraft – its uniform motion in a straight line – has changed, which should give a first approximation of the amount collected.

When the sample comes back to Earth, it will be analyzed by an international team of scientists who will measure all aspects of the material’s composition and structure, especially the organic and water contents of the soil.

This is when we’ll get some answers, which will tell us about our own origins as much as about the origin of asteroid Bennu.

Airbnb recruits ex-Apple design honcho Jony Ive



Next time you stay in an Airbnb you better expect some aluminium sides, some polished and laminated leathers, and, potentially, the most innovative flat you’ve ever stayed in. That’s right people, Airbnb has brought on Jony Ive, the ex-Chief Head of Design at Apple.

If you’re unfamiliar with Jony Ive, he’s the man behind lots of your favorite thingsHe left Apple last year after almost 30 years at the company. During that time, he oversaw the development of almost any modern Apple product or service you want to name, from the iPod to the Apple Stores themselves. Even more importantly, he helped build the design team that’s still pumping out quality shit to this very day.

Anyway, after Ive left Apple, he formed his own company: LoveFrom, an organization so exclusive it doesn’t appear to even have its own web page. I assume this is the internet rich dude version of a bar with no sign.

The reason I mention LoveFrom is because that’s who Airbnb has made a deal with, not Ive directly.

The flat-sharing accommodation chain’s CEO — Brian Chesky — announced this collaboration in on its blog. Chesky wrote that Airbnb and LoveFrom will be “engaging in a special collaboration,” working together through a “multi-year relationship.”

The goal? Well, that’d be to “design the next generation of Airbnb products and services” and help “develop its internal design team.”

What this actually means — according to the Financial Times — is that Ive will overhaul Airbnb‘s app and website, one element of this being revamping the site’s rating system for guests and hosts.

All this is exciting, but a shame if you were expecting a fleet of swanky new Airbnb complexes that are an engineering feat, managing to distill the essential form of humanity into a relevant architectual mechanism. You’ll have to make do with a new website instead.

Airbnb has been hit hard by the pandemic (bookings were down by 80%), but it is bound to survive. Which is a little bit of a shame because it has been a driving force behind gentrification, rising rents, and the housing crisis. Why can nothing useful also be moral?

Obviously Ive going there is unlikely to make the company change (which is a shame), but it will probably improve the service (which is good). So maybe it’s a net neutral for everyone.

Well, aside from Airbnb‘s current Chief Design Officer, Alex Schleifer, who is “stepping down” following this news. I’ll pour one out for you, pal.

Adobe’s new AI experiment syncs your dance moves perfectly to the beat



TikTok has made on-beat dances and movements mainstream. But what if you went offbeat or the video you recorded had some lag to your perfect dance moves. Adobe can fix that for you.

The company showed off an AI-powered experiment at its Adobe Max conference that syncs your off-beat movement to the beat of the music. Researchers used computer vision to follow the body movement of the person in the video. As shown below, the algorithm also analyzes dance moves through popping orange circles to determine the time of movements.

The researchers also mark beats of the music track with orange lines and plot them against the orange dots to determine if dance moves are in sync with the music.

Adobe uses this analysis to match beats of the song with corresponding movements to make a perfectly synced video. The company said that the algorithm can take random videos of people dancing and sync them with a track, making it look like they’re dancing to the same song.

While this is just an experiment, it could be handy for creators to video editors. I wouldn’t be surprised if we see such functionality making it to TikTok or Instagram Reels in a few years.
