Privacy Considerations for 4 types of people

blog.devgenius.io/privacy-sett…

in reply to The New Oil

Frankly, this is a pretty low-quality article. There are a lot of typos and grammar errors, and much of the advice is questionable at best, like recommending people keep location tracking on. It's also unclear to me how the "four types of people" are actually represented in each section. I find most of what you share insightful and helpful so this surprised me.

@rolltime Agreed, It excludes teenagers in some categories and lacks depth.


Our universe is speckled with stars, with billions just in our galaxy. Some stars live alone or in twos or threes, but others are bound together by gravity into much larger communities. In honor of @NASAHubble’s exploration of #StarrySights, let’s talk about star clusters! 🧵 1/6
#NASAUniverse


Globular clusters are stellar "dinosaurs" scattered throughout the universe, containing some of the oldest stars in the universe. These clusters can contain anywhere from tens of thousands to millions of stars, packed tightly together in a dense clump. 3/6
#NASAUniverse


Star clusters are divided into a few different types, based on how many stars are in a cluster and how tightly they’re bound by gravity. Stars in clusters typically have a shared origin, and they can live very close together or can be spread out over hundreds of light-years. 2/6
#NASAUniverse


Open clusters have fewer members, usually a few hundred stars or less. Most open clusters are much younger than globular clusters, and they’re also much less dense and less tightly bound than globular clusters. 4/6

Just to let you know that your threads do not have the posts linked to each other, plus they are not being posted in order.


Scientists are interested in how star clusters form and evolve. Some disperse and spread out over time, while others remain tightly bound together by gravity. The different types of stars in clusters also have various life spans, so they change and die off as a cluster ages. 5/6
#NASAUniverse


Many different @nasa observatories study star clusters using different types of light. Alongside @NASAHubble, we’ll be highlighting how some of our other telescopes help us learn about these stellar communities! 6/6

Electronics question – LED resistors, boosts welcome

I pulled apart an LED bulb. I can't remember the lumens but think it was 200lm. I want to use the individual LEDs with an Arduino but don't know what resistor to use with each as I'm not sure how big a punch each one packs. The resistor for all 36 tiny LEDs is in the second photo – looks like [brown black black black red] to my eyes.

Any idea how I can calculate the resistor needed for one bulb please?

Electronics question – LED resistors, boosts welcome
Did you get an answer? The basic idea is to use Ohm's law with a twist. The voltage drop across the LED is constant and depends on the color. Say you apply 5V to an LED with a series current limiting resistor, if the LED is green it will drop 2.2V. that leaves 2.8V dropped across the resistor.

Electronics question – LED resistors, boosts welcome

V=IR, V/I=R if you want 100mA to flow thru the circuit take 2.8/0.1 and you get 28 Ohms.

It is always a good idea to use a current limited power supply for testing.

I'm not an EE so only know enough ot cause trouble. Corrections welcome.

Electronics question – LED resistors, boosts welcome

phew! Oh yes, thank you for checking and for the thoughful reply.

Many answers in the replies said exactly this (note the post was nearly a year ago...I have since wired it all up, completed the artwork and exhibited it at three venues!) but much appreciated for taking the time.

in reply to Fionnáin

Electronics question – LED resistors, boosts welcome
Thank you for your kind reply. I'm still very new to Mastodon. It seems that the the number next to the reply arrow is not the number of replies. But if I touch the test of your post I'm taken to a different view where I see all the replies. That is confusing.
in reply to George Albercook

Electronics question – LED resistors, boosts welcome

yes there are some things here that take some getting used to, and a few small bugs because Mastodon is non-commercial and it is up to users, not teams of paid testers, to report errors.

There are also other reasons you might not see replies on an old post. Eg:

1) Many people automatically delete old posts
2) Many people reply privately
3) Some people's instances may not be 'federated' with your instance

in reply to Fionnáin

Electronics question – LED resistors, boosts welcome

the third example above is one that can be hard to understand as a new user, but becomes easier over time. There are plenty of explanations online about federation but I learned mostly by just interacting on here and picking up meaning slowly.

And welcome to Mastodon!

interesting. So I don't see any replies. Do you know why?

"Self-Hosting Is the Ultimate Privacy Power Move"

When you use a third-party service for your needs, whatever those needs may be, you’re always taking on a certain degree of privacy risk.

I don't see many tutorials on securing your self-hosted Nextcloud service. I love next cloud but I'm always wondering if I'm safe running in on the internet wasteland.
in reply to Nextcloud 📱☁️💻

I can definitely see the appeal to self hosting a lot of things, maybe if I ever have enough space for that sort of thing I'll look into it again some day.

If it works well on the Steam deck does this mean it will usually work well on desktop Linux with Steam?


You may think it’s very lonely to be a crew of manikins aboard a spaceship flying to the Moon, but the reality is that we managed to fit a lot of companions into the @NASA_Orion spacecraft!

The Lunar Flashlight mission is set to launch no earlier than Nov. 30. Once it's in orbit around the Moon, this briefcase-size satellite will use lasers to light up dark craters as it hunts for hidden water ice.

We won't have this view again anytime soon - DRO (distant retrograde orbit) is for Artemis I, while lunar flyby will be used for Artemis II!


Because we recently broke the Apollo 13 record for farthest distance of a spacecraft designed to carry humans to deep space and safely return them to Earth, I want to acknowledge my namesake, who is known for his contributions to the Apollo 13 mission. 1/9 go.nasa.gov/3GSnkM5

Arturo Campos (the human) grew up in Laredo, Texas, hailing from a Mexican-American family. He started working at his dad’s auto mechanic shop, and went on to earn an engineering degree before joining @NASA_Johnson in the 1960s. 2/9 go.nasa.gov/3ijsers

Arturo Campos dived into the rescue effort. Thinking on his feet, he rewrote a plan to divert electricity from other parts of the spacecraft into the ship’s essential systems. The plan was relayed to the crew via mission control. 6/9

I did it. I made music on a TI-83 graphing calculator. This is insane. Massive shout-out to @jefftheworld for letting me know this exists. Man was this a pain to get up and running. I still run into a problem where it only plays the first note and then nothing else. I find if I leave row play mode off it doesn't do that but I'm stumped as to what it could be causing it. The only thing that solves it is reinstalling. Yikes! Well, it works. For now. Gotta get the emulator up and running so I have a more reliable platform to work with the tracker. Then I can port the ROM over to the calculator.

It was no easy fix, but it got the job done. Four days later, the Apollo 13 astronauts splashed down in the Pacific Ocean, exhausted but safe. Campos helped save their lives. 7/9 go.nasa.gov/2z23yNl

The Apollo 13 mission would go down in history as a “successful failure” because of the experience gained in rescuing the crew members. Campos’ knowledge played a key role in the team’s efforts. So to me, he’s a hero. 8/9

Stars in globular clusters pack snugly together. Messier 28, for example, crams about 50,000 stars into a region just 60 light-years (350 trillion miles) across. The Sun only has about 400 known stellar neighbors that close. #MondayMotivation

What keeps them from collapsing together from gravity? Were the stars formed from an old expanding supernova?
