Building a tiny Linux from scratch
https://blinry.org/tiny-linux/
Last week, I built a tiny Linux system from scratch, and booted it on my laptop!
Here’s what it looked like:
![](https://m.stacker.news/74052)
Let me tell you how I got there.
I wanted to learn more about how the Linux kernel works, and what’s involved in booting it. So I set myself the goal to cobble together the bare neccessities required to boot into a working shell.
In the end, I had a tiny Linux system with a size of 2.5 MB, which I could boot from a USB stick on my laptop!
What you’ll get out of this article:
- A better understanding of what happens when your computer boots Linux.
- What terms like bzImage, initrd and UEFI mean.
- Ideas for how to deal with the problems that I encountered.
- And if you haven’t used Nix, it might be interesting to see how I used it to manage the tools and libraries I needed.

I tried moving my Google calendar to Proton (and failed)
https://shilin.ca/i-tried-moving-my-google-calendar-to-proton-and-failed/
Basically, the title.
I've been building up the courage to transition since I started de-googling my digital life about three years ago. At first, there was the browser. It was the easiest — Firefox instead of Chrome, obviously. Then there was mail. I learned about SimpleLogin and started using them by routing all my aliases to a single Proton email address. This was long before their partnership with SimpleLogin. Next, I moved the drive and the documents stored in it. Lastly, there was the calendar.
**Why de-googling**
Everything about my life had been hosted within the Google's ecosystem. Personal documents, bank statements, you name it. But Google’s privacy practices have been increasingly concerning, if not alarming. I got tired of them using and selling my data for advertising — my browsing behavior, purchasing habits, and my email conversations. Google was, and unfortunately still is, everywhere. It is on my phone, in my bedroom, and in my friends' houses. The company's main business model is advertising, and so their revenue streams speak for themselves.

Tangem wallet collects and exposes users seed phrase via email glitch
https://cointelegraph.com/news/tangem-security-vulnerability-fixed-private-key-leak
Cryptocurrency wallet provider Tangem has fixed a critical security vulnerability on its mobile app that collected certain users’ private keys via emails.
The fix came after Redditors repeatedly called out Tangem for putting investors’ funds at risk by exposing their private keys on email accounts and to Tangem employees.
On Dec. 29, a Reddit discussion on Tangem’s operations gained traction, which accused the wallet provider of stealing private keys using emails. The Redditor, u/areklanga, further accused Tangem of not providing “any sensible reaction” when the issue was pointed out previously.
Tangem acknowledged the issue on Dec. 30 and stated the incident arose from a bug in the mobile app’s log processing, which had now been “fully resolved.” Tangem also provided a breakdown of the situation.
Tangem’s official website, which logs all version updates of its mobile application, did not mention the details about the Dec. 30 update.
Tangem also confirmed in its Reddit response that “all logs and attachments sent to its support team were permanently deleted, ensuring no residual data remains.”
While Tangem pushed out an update on Dec. 30 to prevent further leaks of seed phrases, the crypto community members called out the wallet provider’s muted response. Tangem did not respond to Cointelegraph’s request for comment.
Tangem has not made any official announcements on its official social media channels, Twitter, Discord, or Telegram, as of Dec. 31. However, all Tangem users are advised to immediately update their mobile applications to avoid seed phrase leaks.

What’s the Most Interesting Way You’ve Used #Bitcoin?
Please share the most interesting, unusual, or downright surprising way you've used Bitcoin.
A few years back, I was traveling through a remote area in Eastern Europe, where cash still ruled and card payments were pretty uncommon. One evening, I found myself in a small village, needing a place to stay, but I had completely run out of local currency, and the nearest ATM was a day’s walk away. I ended up chatting with the innkeeper, and to my surprise, he’d actually heard of Bitcoin! Since I’m a proud Bitcoiner, I offered to pay for the room with Bitcoin. He was curious but agreed—as long as I could show him how to set up a wallet. So that night, not only did I find a cozy place to stay, but I also helped introduce someone to Bitcoin for the very first time.
