I'm $200 a month richer and so much happier.
$60/month for internet and maybe $20 for a couple of streaming services with ads.
Oh - and my @tablotv.bsky.social - Love my free local channels streaming from my Tablo to my Roku!

I call him "Sprite-Man" - yeah he's a bit creepy, I still love him. 16x32 pixels at RGB 3:3:3 color depth in a single FPGA RAM. He's part of my VGA graphics controller project.
Instead of 512 CPU writes to draw "Sprite-Man", a single CPU write will relocate him anywhere on the 1280x1024 display.

Finally got my frame buffer working. Very RAM limited on this chip so it is 320x256 at 9 bits even though the hardware DACs are 1280x1024 12 bits.
Side-by-side of my FPGA 9bit frame buffer versus original image at 24 bits RGB.

Analog VGA could have been over a 5-conductor TRRS 3.5mm headphone jack! I suppose the single return may have created some issues.

Would have been really cool if a single SYNC would have been used for both VSYNC and HSYNC. Then it would be just 2 I/O pins and GND. I see no reason why this couldn't have worked - a really long SYNC pulse is VSYNC, a really short SYNC is HSYNC.

VGA is really amazing. I hate to see it go the way of floppy disks and CDRs. I know that eventually it will. My video capture is actually from a VGA to HDMI adapter and then a HDMI to USB stick. I should probably by some spares. I hope to still be playing around with FPGAs for another 30-40 years.

No, a TRS-80 Model-1 about a decade earlier late 1970s. Started out with 4KB of RAM, upgraded to 16KB. The cassette tape for storage was a real drag. This was followed by a Franklin ACE 1000 Apple //+ clone, then the Apple //c. Nothing but IBM PCs and Sun workstations after that. Life's been good.

YES! There is definitely a lot of that.

I hate that I'm still going to Twitter for breaking news.
Bsky is such a friendlier place - but extremely lacking in the news department. My compromise is I don't post to Twitter anymore. I only read there.

It always kills me that my 12lb Chihuahua / Poodle mix is forever picking fights with 120+ pound dogs that can easily be mistaken for horses or moose.

I "ripped" all of my floppies to *.dsk format an go through them every once and a while on AppleWin emulator. Fun to read through my BASIC code I wrote as a kid. Choplifter never gets old.

Sold it to my college roommate in 1990 for a 80386. Had the foresight to keep my original floppies. In early 2000's I bought a //c off of eBay for $100 and enjoyed playing 8bit videogames of my youth with my kids. Haven't turned it on in twenty years now. Afraid to. I like thinking it still works.

Right @jeriellsworth.bsky.social ?
I can't believe this hasn't caught up to me.
I should be a Mad Hatter by now.

That was me upgrading my old Linux workstation from 60 to 500 GB SSD. Thought I knew what I was doing. Forgot completely about Logical volume management. Thankfully friends online reminded me of this forgotten LVM knowledge and came to my rescue. Good to have tech friends.

I'm actually ready for the absolute shit-show to start.
I feel mentally prepared for it this time.
Let the chaos begin. I feel at peace with surviving Nero letting Amerika burn. Hopeful we will emerge a better country in the end. Like Germany did.
And if Canada takes over, I'm okay with that too.

Love this! I wanted the Heathkit 6800 CPU trainer SOoooo bad back in the late 1970's. I ended up getting a Tandy TRS-80 Model-1 instead, which was probably the better move.

At some point, Toyota has to start worrying about losing market share to Elon Musk here.

@nytimes.com offered me $4/month for 12 months.
I couldn't say "No" to that.
The Atlantic is a solid choice. Huge fan of everything @radiofreetom.bsky.social writes - even his books.

Sure sounds like Elon Musk wrote that tweet above, doesn't it? Busy guy that Musk.

I was an eight year subscriber to @washingtonpost.com .
I canceled, along with so many others, when owner Jeff Bezos bent the knee to Donald Trump and forced the paper to cancel their recommendation of Kamala Harris for POTUS.
If they get rid of Bezos, I will sign up and again be a loyal subscriber.

I got this book for Christmas. It's quite the fascinating read, starts way back in the 1930's with the UK occupation of Palestine.

I feel like we're at the point where for $20 we should get an AI generated Taylor Swift concert projected live in our living room.
