October-23 will be bullish or bearish for #Bitcoin?
Honestly, I don't know?
All I know that 5 years down the line these discussions will not even matter.
Explain UTXO in Bitcoin like I'm 15
Imagine you have a wallet with some Bitcoin in it. Now, these Bitcoin are not like physical coins or notes you can hold in your hand. Instead, they exist as digital units on the #Bitcoin network.
UTXO stands for "Unspent Transaction Output"
It's like keeping track of how much Bitcoin you have in your wallet. Whenever someone sends you Bitcoin, it creates a new UTXO for you. This UTXO represents the specific amount of Bitcoin you received.
Now, when you want to send Bitcoin to someone else, you need to use one or more UTXOs. Think of it as if you're breaking down a larger bill into smaller ones to pay for something.
For example, if you received 10 Bitcoin and you want to send 3 Bitcoin to a friend, you'll use one of your 10 Bitcoin UTXOs and create a new UTXO for your friend with the remaining 7 Bitcoin.
The cool thing is, once a UTXO is used in a transaction, it becomes "spent" and cannot be used again. It's like crossing it off your list of available funds. This ensures that people can't spend the same Bitcoin twice.
That's the basic idea of UTXO in Bitcoin. It's all about keeping track of how much Bitcoin you have and using those UTXOs to send or receive Bitcoin securely. π€πΈ

QR codes in Email Phishing
QR codes are everywhere: you can see them on posters and leaflets, ATM screens, price tags and merchandise, historical buildings and monuments. People use them to share information, promote various online resources, pay for their goodies, and pass verification. And yet you donβt see lots of QR codes in email: users often read messages on their phones without any other device handy for scanning. As such, most letters come with ordinary hyperlinks instead. Nevertheless, the attackers increasingly turn to QR codes delivered through email.
Unlike phishing links that are easy to check and block, QR code is a headache for security solutions. It takes costly and resource-heavy computer vision technology to analyze QR codes and find out what information they contain.

FOR ANDROID USERS: INSTALL "BINARY EYE" ON F-DROID OR NEO STORE. ALWAYS SCAN QR CODES THROUGH THIS APP.

Your child's privacy is worth more than likes
Sharenting and its implications for children's privacy
Some parents love to share pictures and videos of their children online. Pictures of the newborn baby or that first smile; a video with the first steps, the first visit to the swimming pool, parties, trips, family moments; then perhaps posts with funny stories, intriguing questions, and even sensitive conversations, such as a teenager revealing to the parent that they are non-binary. This behavior even has a name: sharenting, or documenting your childβs life online. And it has serious implications for children's privacy.

Apple emitted patches this week to close security holes that have been exploited in the wild by commercial spyware.
The updates, which were issued yesterday and should be installed as soon as possible if not already, address as many as three CVE-listed flaws. We've just learned today that the Predator spyware sold by Intellexa used these vulnerabilities to infect at least one target's iPhone.

Mullvad VPN completes migration to disk-less VPN infrastructure
VPN provider #Mullvad announced today that it has completed the migration to a disk-less VPN infrastructure. The migration to servers that operate fully in RAM strengthens user privacy further and it also improves reliability and management of #VPN servers.
Mullvad started the migration in early 2022 with two test WireGuard servers. The company created a special bootloader, stboot, for the purpose and continues to use a custom Linux kernel that is a heavily slimmed down version of the mainline branch.
