The main mistake with the Sega CD was adding a bunch of expensive new hardware to it. It gave the Genesis a second, faster Motorola 68k and a special ASIC to handle sprite scaling and rotation effects (to compete with the SNES), but these i

I made a few simple Mac apps in Objective-C during the pandemic in 2020, and I was struck by how hard it was to find tutorials and examples on how to do anything in Objective-C. It's possible I was looking in all the wrong places, but

What’s so hard to understand about Edge pretending to be Chrome pretending to be Safari, using Blink pretending to be WebKit pretending to be KHTML pretending to be Gecko, all pretending to be Netscape Navigator? I’m the dude playing the du

There’s a Japan-only game for the Sega Game Gear called Kinetic Connection that plays similarly but involves rearranging a scrambled picture rather than moving colored blocks into a pattern. https://segaretro.org/Kinetic_Con

You can we we advocate for this position in a less snobbish way. It’s times like this I feel like a real idiot for expecting more from this site than the average Reddit trainwreck comment thread. Guess what, you’re not that much better than

"And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because death is very likely the single best invention of life. It is life's change agent. It clears out the old to make way

The YouTube channel 3Blue1Brown has an "Essence of Linear Algebra" series that I found helpful (along with an Essence of Calculus series and videos on other tricky subjects such as differential equations and Fourier transforms). I

They've actually been warning users since Catalina (if not longer) when the following are run: python irb php --version tclsh For PHP, it also shows up in Apache's server string: Apache/2.4.46 (Unix) PHP/7.3.24-(to be re

The UI changes weren't especially popular, but I don't think they were the cause of a mass exodus. I think it's more that Reddit was gaining in popularity. Slashdot posts had to go through their "editors," who were

Slashdot tried to solve this problem by making mod points limited and requiring you to give a reason for moderating a comment. Then there was a metamoderation system where you decided if the moderation someone gave was fair or not. If someo

I haven't used Tcl for anything in ages, but I have a book on it that I thumb through sometimes because it's so bizarre and fun to read about. For example, you can delete or rename procedures on the fly, including built-in procedu

There’s definitely something uniquely satisfying about knowing that code you wrote is saving other people time or helping them create things. The beautiful thing about programming is you can solve a problem once for yourself and also end up

The short squeeze happened two weeks ago when the stock ballooned from $20 to $480. That's a 24x increase; VW's "infinity squeeze" comparatively only grew 5x from $200 to $1000. People on WSB had some arbitrary price tar

If we're separating the federal district, why not just give the rest of it back to Maryland the same way the area on the other side of the Potomac was given back to Virginia?

That’s how I hear it in my head, probably from years of reading it as a stand-in for profanity on Slashdot and the like.

My experience was that Flash ran like garbage on anything but Windows/Intel. Linux/Intel? Trash. Mac/PPC? Trash. The web at the time was unusable on my PowerBook G4 without FlashBlock. Maybe Flash would still be around if Ado

Honestly, most of the trades are baffling to me. A generator is a lot more valuable than a camp stove. A snowmobile is a lot more valuable than a keg and a sign. I'm not sure there's any insight to be gleaned from this except that

Mac OS has had a built-in file versioning system (separate from Time Machine) since Lion or so that works with any program that uses the standard document saving APIs. Most Mac users probably aren't aware that their computer stores pot

I would guess that Apple doesn't want any controversy from their media side harming the reputation of the other parts of the company, which is probably a sensible decision. Netflix is in a different position since the "media part&

I agree that there's a middle ground here. I think the point of the "you can do anything if you try" sentiment is to push people to overcome their self-limiting beliefs. I've certainly accomplished a lot of things I didn

They wrote it, so they could close its source regardless of the license (which was actually Apache 2 and APSL before that). It looks like 10.9 (released in 2016) was the last release on https://opensource.apple.com/ that in

PHP requires escaping quotes and literal backslashes (i.e., backslashes not used for metacharacters or escaping other characters). For many cases, it doesn't affect anything, but it can turn into a bit of a nightmare if you're mat

PHP half-copied Perl a lot. Another example is implementing arrays and hashes, but not as separate types. So you have odd behavior like the array sort functions sorting values but not renumbering keys because there's no distinction bet
