*siiiiiigh* I just realized that Justin's FutureSex/LoveSounds album is 20 years old this year...

One of the biggest albums in 2006... you couldn't go anywhere without hearing someone blasting this album.

I really wish Apple made printers and routers again. 😅
Someone get this app an Apple Design Award stat!!! :)

Ahhh! @billy is just so nice! Reminds me of those premium apps you'd buy at the Apple Store (boxed software) that was so premium it even came with a fully-illustrated instructions manual *WITH COLOR PAGES*.

It has its own personality but still undeniably Macintosh. And just look how much production value an app gets when you use fully illustrated art icons (as opposed to just line-art glyphs. They're so pretty!!!

@simonlou is my new favorite designer :P haha

Cleve Moler, #mathematician, cofounder of #MathWorks, and creator of #MATLAB, has died at 86. Say what you will about MATLAB, but its impact on #ScientificComputing is undeniable. As a student, I felt almost rebellious when I started coding in MATLAB instead of #Fortran 🤘

Unless you reach her level of success and status in the world of pop music, maybe keep your mouth shut?

Nothing pisses me off more than people commenting to Madonna that she needs to stop performing/retire because no one wants to see a 67 year old woman "attempt to be sexy."

Yet people cheer on shirtless Iggy Pop at 79 or 76 year old (age at time of death) be wheeled out on a custom throne due to his physical limitations.

Women always being told what to do or not to do while men are cheered on to do what they wish.

Happy to see Madonna still doing what she wishes as a strong, independent woman.

LOL “it doesn’t happen on my computer” is just such a bs response to dismiss a complaint about a bug or usability.
