@tvaziri.com Hello, I require your expert opinion to settle an argument. Was the reflection of the chess board in Judd Hirsch's glasses in the Independence Day chess scene practical or was it CG? www.youtube.com/watch?v=ARNy... Thank you.

Hey everybody, I've made an important discovery. AIs are fundamentally unable to reason about how to mix Objective-C and Swift code within a Swift package. I'm still working out the details, but on the day of the machine uprising, I believe we'll be able to exploit this weakness and defeat them.

Einstein taught us that gravity is not a force. But in a recently published paper, researchers claim that we might have had it wrong this whole time. www.youtube.com/watch?v=MA75...

We have nothing to fear from AI until it is able to reason about multiplatform Xcode project Info.plist configuration. Based on my experience this morning, I estimate that this will take another 20 or 30 years.

How cool is this. Voyager 1 is coasting in interstellar space, more than 48 years & 25 billion miles from Earth. Its back-up manoeuvring thrusters failed more than 2 decades ago. But @NASAJPL have GOT THEM WORKING AGAIN!!!! www.jpl.nasa.gov/news/nasas-v...

NASA’s Voyager 1 Revives Backup Thrusters Before Command Pause
The mission team wanted to fix the thrusters, deemed unusable decades ago, before the radio antenna that sends commands to the probe went offline for upgrades.

No AI, this is a real photo taken by Percy’s engineering cameras of astronomical twilight on #Mars! You can see Deimos in the sky too. I worked pretty hard to plan, execute, and analyze this image, and it came out beautifully! A bit noisy, but it was very dark out after all. #astro #planetary

There's so much bad news in the world. So, here's some wrapping paper designed by Japanese artist Ippei Tsujio that turns everything into bread. A delightful (delicious?) distraction. More info: spoon-tamago.com/bread-wrappi...
Squares of wrapping paper that looks like the texture and color of golden bread. Items wrapped with the paper, which makes them look like bread.

Apparently surface rupture during the Myanmar 2025. I'm very surprised by the weak shaking along the rupture. I'm not sure if this is the main rupture (I would say no - nonetheless, VERY COOL). Author unknown, location Thazi (to be confirmed)

There was a rather charming trend in the 1910s to introduce the actor at the beginning of the film by showing them first in their street or evening clothes and then dissolving into the costume of their characters. Here we see recent stage import William S. Hart become a bandit in THE BARGAIN (1914).

Proposal: When discussing automation, replace the notional always-on, maintenance-free robot helper you're imagining with the average real-world printer you've encountered. The more expensive and complex the printer, the more potential issues and "having a printer guy". A much better baseline.

The Andromeda Paradox is a brain-melting thought experiment that brings up the question of whether the future is still open or already fixed in Einstein's theory of relativity. As I recently noticed, it's even got multiple physicists' brains tied into knots. www.youtube.com/watch?v=i7Rx...

Send Web Links That Jump to the Exact Text You Mean
Sometimes when you share a webpage link with someone, you just want to bring their attention to a specific passage or sentence to make your point, rather than have them read through the entire article. In 2020, Google added a function to its Chrome browser called Scroll to Text Fragment (STTF) that helps you achieve this. It allows URLs to link directly to any visible text on a page. You may have seen it work in Google Search, where clicking on a link in your returned results takes you to a highlighted passage of text further down the page. Since then, Google has built the feature into the open source Chromium code, so most other popular Chromium browsers like Edge, Opera, and Vivaldi also have it these days. (Brave is an exception, citing some privacy risks of STTF.) Copy Link With Highlight in Safari Late last year, Apple joined the club, and brought full support to Safari 18.2. To use the feature, visit a web page and simply highlight the text you want to create a link to, then right-click and choose Copy Link with Highlight from the dropdown menu. The "Copy Link to Highlight" option This will generate a special URL that includes a hash (#) symbol and "text" element, followed by a few words that bookend the selected text. All you need to do is share the link with someone, and when they click it they'll be sent directly to that part of the webpage with the specific passage highlighted, as shown below. The shared link as the recipient sees it That's all there is to it. The Copy Link to Highlight option is also available in Safari on the iPhone and iPad, and indeed in any browser that uses WebKit on iOS and iPadOS. Hopefully that makes it easier for you to direct the recipient of the link to the content you actually want them to focus on. Bear in mind that the look of highlighted text can differ depending on whether the page author has styled it to look a certain way. Also, text fragment linking does not work in PDFs. Firefox users: You'll need to install Thomas Steiner's Link to Text Fragment extension, which will add a Copy Link to Selected Text option to the contextual menu.
