I Think The Key To Celebrities Who Survive Tumblr Is That They Understand We’re Not Here To Follow

Hello again, Labs here with a recap of our test of Collections! We introduced this prototype back in September and then handed the feature to a handful of volunteers sourced from the notes on that post. Thank you again to all volunteers! 

We got so much useful feedback, and wanted to share some of that here, and reveal some next steps we’re taking. There are a couple of big projects cooking in Labs, and Collections has taken a backseat lately, but it is important to us to not leave y’all hanging. We very much want to build things with you here.

Our goal with the volunteer-based super-early phase of Collections was to see if those volunteers actually use the feature, watch what they come up with, and check whether anybody they invite to Tumblr signs up and becomes a regular user of the site. Turns out, nobody did sign up — it’s not as useful of an onboarding strategy as we thought it could be.

However, one piece of feedback we got is that Collections make great custom feeds, which people on Tumblr have been asking for a lot over the years. We hear you loud and clear: you want to supplement the standard Following / For You experience with more intentional control over feed content. That’s really important to us.

With that in mind, for those in the prototype, we’ve moved the Collections list to the left sidebar / mobile navigation as an expandable area like Account, for quick access. We like this better than putting them in the dashboard tab bar, but it’s still something we’re mulling over:

We also heard the need for more filtering options beyond just blogs and tags. What about only including a blog’s posts that use a certain tag, or excluding posts using a certain tag? Or list tags with a boolean AND operator (“posts tagged [tag] and [other tag]”), not just the OR operator we’re using now for sourcing tagged posts. Lots of ideas on how to further customize what shows up in the feed, and better define what the feed is “for”.

There were other fun, tangential bits of feedback, too, like the desire to make these Collections a collaborative feature, so that more than one person can help build a Collection. There were also several usability issues that came to the forefront, which we’ve addressed. And there were some well-articulated thoughts and questions about etiquette, such as how to seek a blog’s “permission” to be included in a Collection – that’s something we care a lot about, to help prevent this kind of feature from being a source of abuse.

Another piece of feedback we heard repeatedly is the desire for Collections of posts. This is not really what we intended with what we built, but it’s not too far afield either. We totally agree that having better, easier ways of collecting and curating individual posts would be useful, so we’re going to investigate that as a separate project.

With all of this in mind, we’ve split the work on Collections into two separate tracks:

Shaping this feature as a “customizable feeds” solution, away from an “invite others” tool.

Building a new thing for saving and curating static posts.

Stay tuned here on the Labs blog for updates on when/if we’ll be moving these Collections tracks of work to more people on Tumblr. (If you are one of the volunteers who helped us with Collections, you’ll still have access to it for the time being!)

Thanks for reading! And please reach out to us via Support, the replies here, or your reblogs, if you have any more feedback, as always.

Mars Helicopter: 6 Things to Know About Ingenuity

When our Perseverance Mars rover lands on the Red Planet on Feb. 18, 2021, it will bring along the Ingenuity helicopter.

This small-but-mighty craft is a technology demonstration that will attempt the first powered, controlled flight on another planet. Its fuselage is about the size of a tissue box, and it weighs about 4 pounds (1.8 kg) on Earth. It started out six years ago as an implausible prospect and has now passed its Earthbound tests.

Here are six things to know about Ingenuity as it nears Mars:

1. Ingenuity is an experimental flight test.

This Mars helicopter is known as a technology demonstration, which is a project that aims to test a new capability for the first time with a limited scope. Previous technology demonstrations include Sojourner, the first Mars rover, and the Mars Cube One (MarCO) CubeStats that flew by Mars.

Ingenuity does not carry any science instruments and is not part of Perseverance’s science mission. The only objective for this helicopter is an engineering one – to demonstrate rotorcraft flight in the thin and challenging Martian atmosphere.

2. Mars won’t make it easy for Ingenuity.

Mars’ atmosphere is around 1% the density of Earth’s. Because of that lack of density, Ingenuity has rotor blades that are much larger and spin faster than a helicopter of Ingenuity’s mass here on our planet. It also must be extremely light to travel to Mars.

The Red Planet also has incredibly cold temperatures, with nights reaching minus 130 degrees Fahrenheit (-90 degrees Celsius) in Jezero Crater, where our rover and helicopter will land. Tests on Earth at the predicted temperatures indicate Ingenuity’s parts should work as designed, but the real test will be on Mars.

3. Ingenuity relies on Perseverance for safe passage to Mars and operations on the Martian surface.

Ingenuity is nestled sideways under Perseverance’s belly with a cover to protect the helicopter from debris during landing. The power system on the Mars 2020 spacecraft periodically charges Ingenuity’s batteries during the journey to the Red Planet.

In the first few months after landing, Perseverance will find a safe place for Ingenuity. Our rover will shed the landing cover, rotate the helicopter so its legs face the ground and gently drop it on the Martian surface.

4. Ingenuity is smart for a small robot.

NASA’s Jet Propulsion Laboratory will not be able to control the helicopter with a joystick due to delays communicating with spacecraft across interplanetary distances. That means Ingenuity will make some of its own decisions based on parameters set by its engineering team on Earth.

During flight, Ingenuity will analyze sensor data and images of the terrain to ensure it stays on a flight path designed by project engineers.

5. The Ingenuity team counts success one step at a time.

Ingenuity’s team has a long list of milestones the helicopter must pass before it can take off and land in the Martian atmosphere.

Surviving the journey to and landing on Mars

Safely deploying onto the Martian surface from Perseverance’s belly

Autonomously keeping warm through those intensely cold Martian nights

Autonomously charging itself with its solar panel

Successfully communicating to and from the helicopter via the Mars Helicopter Base Station on Perseverance

6. If Ingenuity succeeds, future Mars exploration could include an ambitious aerial dimension.

The Mars helicopter intends to demonstrate technologies and first-of-its-kind operations needed for flying on Mars. If successful, these technologies and flight experience on another planet could pave the way for other advanced robotic flying vehicles.

Possible uses of a future helicopter on Mars include:

A unique viewpoint not provided by current orbiters, rovers or landers

High-definition images and reconnaissance for robots or humans

Access to terrain that is difficult for rovers to reach

Could even carry light but vital payloads from one site to another

how staff decisions are made at tumblr

Manager: ok sorry for bringing you all in for a morning meeting but it's kind of urgent

Dave, an australian: its midnight here, fuck you.

Manager: yeah sorry dave. it's just. people have been talking and. we're still short on money.

Moss, already on xeir fourth cup of coffee for the day and tired of everyone's shit: how the fuck are we short on money again.

Edna, who definitely doesn't have a suspicious secret tumblr blog about organ harvesting: have we tried selling everyone's organs?

Manager: thats the fourth time this month you've suggested that, Edna, the answer is still 'no'.

Edna: >:-(

Keith, who is definitely high and has been using his phone instead of paying attention to the meeting: omg... twitter users have to pay eight dollars a month to get verified now lmaoooooo. Hey wait guys you know what would be funny?

programmers, already writing out code: yep, on it.

Manager: and the employee of the month award goes to Keith

We can always fix it later
