No, Linus Torvalds is not Bitcoin’s legendary creator Satoshi Nakamoto

One of the great tech mysteries is “Who really is Bitcoin’s inventor, the mysterious Satoshi Nakamoto?” Recently, some people thought Linus Torvalds, the developer behind both the world’s most popular operating system, Linux, and its most popular development tool, the Git distributed version control (DVC) system, had also claimed he was the world’s most popular cryptocurrency, Bitcoin, inventor: The perplexing Satoshi Nakamoto.

This story got its start in the cryptocurrency news site, BeInCrypto. There a writer argued that “Linux creator Linus Torvalds seems to be claiming that he is Satoshi Nakamoto, the father of Bitcoin. Is he joking or is this the real deal?”

he reason for this claim? In a GitHub Linux kernel repository, it appeared Torvalds had changed a single line in the Linux Kernel. The change: ‘Name = I am Satoshi.’

And people were off to the races. News stories appeared here, there, and everywhere. The big question “Is he or isn’t he?” was debated on Twitter, Reddit, and Ycombinator.

Back in the late 2000s, no one really cared. Yes, there was a paper entitled, Bitcoin: A Peer-to-Peer Electronic Cash System” by Satoshi Nakamoto, but so what. There had been lots of papers that went nowhere. But then Nakamoto released the first Bitcoin program, version 0.1 on an early open-source code site, SourceForge, and launched the network with the genesis block of bitcoin aka block number 0. The race to cryptocurrency had started and it’s still going on today.

But, then and now, we still don’t know who Satoshi Nakamoto really is. Nakamoto, who never revealed any real clues as to his identity, stepped back from active Bitcoin involvement in mid-2010. Since then, he’s vanished from the internet.

JFrog Helps Clean up Bad npm JavaScript with 3 New Tools

When Microsoft acquired JavaScript Node package manager (npm) company npm, with its over 1.3 million packages and 75 billion downloads, I’d hoped that some of npm’s notoriously unstable releases would finally be fixed. I hoped in vain. For instance, the recent npm libraries ‘colors.js’ and ‘faker.js’ mess showed that we haven’t improved much from 2016’s infamous, ‘left-pad npm’ episode. In all three cases, tens of thousands of npm programs went up in smoke.

So it is a good thing that JFrog, a company that uses DevOps principles to secure the software supply chain, has released three new open-source programs to detect and block the installation of malicious npm packages.

Attempt to shake down Linux users for Netfilter code use resolved

Once upon a time in the 2000s and 2010s, Patrick McHardy was the chair of Linux’s Netfilter core development team. Netfilter is a Linux kernel utility that handles various network functions, such as facilitating Network Address Translation (NAT) and Linux’s IPTables firewall. All was fine. But, then it was discovered that McHardy had made millions of Euros from threatening over 50 companies with legal action for using “his” code. That will never happen again.

McHardy was suspended from the Netfilter team in 2016. The Netfilter team released a document on how to deal with his attempts to extract money from vendors. This move by McHardy, who had been a leading Linux developer in the 2000s, came as a complete surprise at the time. Now, years later, the issue has finally been resolved.

On January 24, 2022, the Netfilter project announced a legally binding settlement with McHardy. This settlement has been ratified in a German court decision. This settlement governs any legal enforcement activities concerning all programs and program libraries published by the Netfilter/IPTables project and the Linux kernel.

Don’t cheap out on essential hardware

On the Reddit SysAdmin group, I recently read a horror story. A car dealership had been using a 14-year-old desktop for its one and only business server. On it, the company was running two business’ customer-relation management (CRM) programs and their inventory management systems. They also—brace yourself—didn’t have an automatic backup system.

The consultant told them that “they should automate backups to a separate system, or use a RAID1 at least. Something!”

Their response? “Nope, too expensive, we can’t afford a new desktop, and we can’t afford new drives.”

A year later, almost to the day, the call came. The drive had failed. Their $20-million business had lost the last six months of data, the client database, client forms, banking documents—everything. “The only reason they even have anything is because I convinced the owner to at least let me come in and do a manual backup six months ago.”

I wish this example were unique. It’s certainly terrible. Indeed, it might even be a business killer—the verdict’s still out on that—but there’s nothing unique about it.

Will World War III begin in cyberspace?

People die because of cyber wars, even if no bullets are ever fired. Instead, they die in emergency rooms that no longer have power, from broken medical communication networks, and from riots. All of this has happened before. It will happen again. And now, with Russia poised to invade Ukraine and Russian cyberattacks already in motion, we can only hope and pray that what promises to be the first major European war since World War II doesn’t spark the next World War.

If it does, I fear the proximate cause won’t be Russian T-90 main battle tanks trying to smash their way into Ukraine’s capital, Kyiv. It will be the Russian GRU Sandworm hacking group launching a cyberattack that perhaps wrecks the European Union power grid; or knocks out major US internet sites such as Google, Facebook, and Microsoft; or stops 4G and 5G cellular services in their tracks.
