Thank you @M0YNG.

Hello everyone - I am Ramakrishnan. My callsign is VU3RDD and I live in Bangalore, India. I am interested in homebrew electronics and I mostly operate HF/CW at the moment. I have inverted V antenna for 40 and 20m bands.

I do computer programming for a living and work on low level software, cryptography and network protocols..

I have another account but i thought of separating the radio/electronics toots into a separate account.

A lot of the #internet has become dependent on Cloudflare, so any reliability issues with that will cause catastrophic failures.

People think they need Cloudflare for DDoS protection (it's a digital protection racket), and the DDoS problem exists because data is not sufficiently federated/distributed across servers/peers.

So to fix the reliability of the internet, more redundant data storage is needed. This isn't anything very advanced though. Torrents are redundant storage. Federated posts in the fediverse are redundant storage. Most traditional server systems and walled garden data silos are fragile.

In honor of World Give Up GitHub day, here's a quick guide to how to serve up your own git repos.

In an empty directory readable from WWW (that has the URL you want your repo to have, for cloning) that you also can write to over SSH, run

git init --bare
mv hooks/post-update.sample hooks/post-update

Make sure the directory has the permissions you want for web (world readable, not writable).

Set the SSH path to the directory as a remote on your local copy of the repo, and push to it and you're done.

The few interactions I had with the online Emacs community have been so pleasant so far!

I definitely felt welcome! A really nice experience.

There's probably a lot to learn from there for other online tech communities.

* emacs-help mailing list, melpa review, and the Emacs french meetup.

The thing that motivates me to continue writing software is seeing how much damage it is causing to the environment & society, and hoping I can push back against that!

And do so humbly. Because I get quite annoyed at devs saying "you must embrace this, it is The Future!" Especially in relation to blockchains where this callous attitude can actively harm others financially.

SPRAT summer 2022 edition arrived. Very intrigued by the T41-EP's CW decoder but unable to decipher what they mean by "..hypergeometric mean for adaptive coding via a bimodal histogram, correlation analysis and a binary search tree to actually find and display a letter". Anyone know of a more detailed article that explains that cryptic sentence?

"Yeah bro I'm super into #crypto what's your favourite block cipher?"

Today I learned that there is an $89 open source SIP phone. Open hardware and software, plus it has room for expansion boards. One such expansion board is a LoRa radio.

There is a Pro version ($139) which is the same hardware, but it has an aluminium frame, as opposed to being polycarbonate.

#OpenSource #Hardware boosts welcome, esp. from #HardwareDev folks!


I have a very basic iambic mode A keyer working. Now to integrate it with radioberry system .. Need ways to set CW speed and sidetone freq from the GUI, so I am going to add some custom CAT commands to query them off the "radio" (SDR software) which is the main place where "state" exists.

Playing with raspberry pico and teensy this weekend in an effort to get a quick and dirty keyer running.

If "Share The Road" feels more difficult/dangerous than it used to, it's because it is.

Made a few QSOs with the homebrew 100W amplifier (Jim Veatch's design and PCB), a 1W Pre-amp (Gopan, VU2XTO's design) and a furuno LPF (furuno's design) and a radioberry R-Pi Hat designed by Johan PA3GSB (with a controller board, again designed by Gopan VU2XTO). OK, I wrote some software (or rather modified some) and connected them all together and managed to let the smoke out of the 1W pre-amp once.

Still it is an awesome feeling when RF goes out via an equipment you wired together.

“How Emacs made me appreciate software freedom” (2021)

Lots of important takeaways from a non-CS, autodidact #Emacs user, in particular on the importance of (self-)documentation and lack of language barriers in the learning process.

#FreeSoftware #PracticalUserFreedom

I don't know if Ram @vu3rdd and I can claim the first international meet up but we had a good chat when we met at my hotel in Bangalore last Thursday.

I got my upgraded license today. The new callsign is VU2JXN. Unfortunately, my online identity is very tied to my old callsign.

@khinsen I agree that it’s frustrating when you’re trying to make a rational choice and emotions get in the way.

However #FreeSoftware development is fundamentally about people. Choosing a software dependency is, in part, choosing whether you’re willing to work (at some level) with the folks who develop it, with their values, tools, and difficulties.

I think it’s a mistake to think one can choose a free software dependency just like one chooses a “product”.

I’ve wondered this same thing about photos of Japan for years, and he nailed it.

crypto currencies 

Just saw a headline, claiming that due to crypto crashing, 200 billion dollars have been "destroyed". Dude that money isn't gone, it was never there in the first place.
