I forgot an #introduction! BBC Micro bot runs your posts on an 8-bit computer emulator.

People create small programs for it in BBC BASIC, a language created by Sophie Wilson in 1981 for the BBC Micro. (She later used BBC BASIC to create the ARM architecture - now the most widely used CPU architecture in the world.)

It's amazing what people create in a few lines of code for a 1980s home computer! You can see 1000s of examples at https://www.bbcmicrobot.com

This is MASSIVE. The Windows Subsystem for Linux in the Microsoft Store is now generally available on Windows 10 and 11! Windows 10 users can now run Linux GUI apps natively! https://devblogs.microsoft.com/commandline/the-windows-subsystem-for-linux-in-the-microsoft-store-is-now-generally-available-on-windows-10-and-11/ #wsl #windows #linux

#introduction Hey Folks,

I'm Duane. I am currently an Associate Professor of Cybersecurity at #ChamplainCollege in Burlington, VT. I have been in infosec for 25 years this year. My experience comes from the government and education sector for 15 years and 10 years in Academia (full-time and 20, total, as an adjunct previously). In just over a month, I will be leaving Academia and working in the private industry. I will miss teaching, though I can’t deal with the traditional model of education in higher education.

Instead I’m teaching in a different form at Cloud Range (where I’ll be working Full Time in January ’23) and am the Senior Adversarial Engineer. I create the cyberattacks and then automate them to run in a live cyber range. We then train existing security teams or folks transitioning to security to identify the attacks. I get to play with some cool products, perform attacks I’ve only read about or did on my own time, create debriefing guides, and perform forensics on my own attacks. It’s an amazing job due to the amount of learning and forensic skills I’m honing. I’m exposed to industries I’ve only learned about in passing about their infosec needs like #ICS. I’m currently learning more and more about #ICS and one of my former students will be my mentor once I’m able to get into in more depth when I’m full-time. I have created two fun attack trainings for ICS and one for PLCs…the automation script for that one is sooo long. :D

I tend to post about the basics of infosec, be an ally for newcomers and those transitioning into the field, and remind folks to perform security control tests.

I’m getting back into metasmithing, but due to arthritis in my neck and managing my chronic pain, I can’t do much anymore so I’m learning to work with precious metal clay…easy on my neck. :). I also like pencil drawing and will be learning procreate on my iPad soon too.

Despite the migration to Mastodon, I’m going to continue promoting using the Matrix protocol and happy to test it with others. I just setup my first Matrix server too. :D

Listen up, newbies 📣

You all want to know how to find interesting people to follow on Mastodon -- and I'm going to tell you how 😃

Go to your instance's profiles directory. This is located on the lower left corner of your screen.

Or visit: https://<nameofinstance.com>/directory

There you can sort profiles by:

* Recently active
* New arrivals only
* From your instance only
* From known Fediverse

See screenshots.

Our CTF (Capture the Flag) contest will again be run by Packet Ninjas who did a great job waay back in 2019 when we last got together IRL. Dust off your hacking skills if you haven't participated in a #CTF in a while. Thanks, Austin, for running this again!

Microsoft is investigating and working on a fix for Remote Desktop issues on Windows 11 systems after installing the Windows 11 2022 Update.

Also, why am I sharing the source code so early in the development?

Working on various projects, I've found that it's always better to open source earlier rather than later.

Rather than waiting for an MVP, it's just better to choose a license and release what you have.

You don't have to enter into an exclusive relationship with one social media platform (aka billionaire)

I think this current urge folks are expressing where they feel they have to select one platform probably stems from corporate tech monopoly's influence on us

It's actually worse for billionaire's if you diversify your tech use - its more difficult to monetize you

Hello! I just moved to hachyderm.io from mastodon(dot)social, so #introduction time!

I'm Pete, I live in Michigan. I'm currently working as a software engineer at a medium-sized marketing outfit hacking on Rails. I used to work at Stripe and egghead with some folks that also happen to be here.

Thanks @nova for the cool instance!

When a GABAergic neuron synapses onto the axon of a sensory neuron, what happens?

Turns out, in the proprioceptors of the locust leg (chordotonal somatosensory neurons), "All the available evidence indicates that the inputs that occur during walking are depolarizing, inhibitory, synaptic inputs."

Depolarizing, inhibitory. How's that possible? Depolarizing because of where the resting potential of the axon is (which is different than the dendrite's), and the particularities of the GABA receptor on the receiving axons. Inhibitory because the depolarization is subthreshold, reducing the membrane voltage potential and, therefore, reducing neurotransmitter release when a spike arrives.

What is this good for? Implementing an efference copy signal: "The rhythmic depolarization at different phases of the step cycle in different sensory neurons may represent a predictive action of the CNS when generating a motor pattern." That is, predicting when the proprioceptor will fire, and by how much, as a function of the self-induced motion. So this signal is subtracted in order to be able to measure (and react to appropriately) any unexpected signal (such as the leg skidding or hitting a rock).

Am I the only person who thought this was a caterpillar at 1st glance?

The number of users by instance in #mastodon is highly unequal. Some servers (mastodon.social) have a significant fraction of the number of users. If the ubiquitous "rich-get-richer" (RGR) phenomenon kicks in, we might end up with a couple of instances having all of the users. But did it kick in? Here is the relationship between instance's size and growth. There is a little bit of RGR, but some of the rapidly-growing instances are small. Decentralization also in how the network grows.
