Citric acid does wonder against battery residue. No idea if this laptop will ever turn on, but I can at least try when I get hold of my universal adapter, this evening

The innards of an old laptop from the . Incredibly, the corrosion did not extend to the motherboard. Still, I'm glad I did not spend more than 5€ on this. Will treat this with citric acid.

Just sent to print two prototypes for my 27C0x0 EPROM adapter for 500 rev5 comps. One is this PLCC32 version, the other is with DIP chips. Will get them in a month, if they work I'll publish everything.

Good morning, I boosted this image the other day but it’s just too good to not also toot

Cleaned up the 500 I got last sunday. Also, noticed I'm running short on 27C400s: need to build an 27C020 adapter so I can fit diagnostic ROMs and a modern kickstart.

Another 500 found at the , complete with cables, expansion and mouse. Thanks to my girlfriend for noticing it and telling me while I was passing by, even though she disapproves my addiction. That's 💕!

Nothing fancy, just flashing some floppy drive before going to bed. These needs to be ready for future projects. I also have a colleague that wants to try one in his

huh this might be fun

<< Apparently a non-trivial number of systems are experiencing #Y2020 bugs. A common Y2K "fix" just postponed things by 20 years, interpreting 00-19 as the 2000s and 20-99 as the 1900s. 20 years is now up, some of those systems are still in use, and they think it's 1920. Oooops. >>

What a curious find at the : a 1888 copy of the A1 Commercial code. You can see how complex messages were translated to simpler words, faster and easier to transmit.

Got my copy of Quartet cart in the mail yesterday! The box looks great, now I need to dust off an MSX for some modern ! @bitsofbas

So I was recently asked why I prefer to use free and open source software over more conventional and popular proprietary software and services.

A few years ago I was an avid Google user. I was deeply embedded in the Google ecosystem and used their products everywhere. I used Gmail for email, Google Calendar and Contacts for PIM, YouTube for entertainment, Google Newsstand for news, Android for mobile, and Chrome as my web browser.

I would upload all of my family photos to Google Photos and all of my personal documents to Google Drive (which were all in Google Docs format). I used Google Domains to register my domain names for websites where I would keep track of my users using Google Analytics and monetize them using Google AdSense.

I used Google Hangouts (one of Google’s previous messaging plays) to communicate with friends and family and Google Wallet (with debit card) to buy things online and in-store.

My home is covered with Google Homes (1 in my office, 1 in my bedroom, 1 in the main living area) which I would use to play music on my Google Play Music subscription and podcasts from Google Podcasts.

I have easily invested thousands of dollars into my Google account to buy movies, TV shows, apps, and Google hardware devices. This was truly the Google life.

Then one day, I received an email from Google that changed everything.

“Your account has been suspended”

Just the thing you want to wake up to in the morning. An email from Google saying that your account has been suspended due to a perceived Terms of Use violation. No prior warning. No appeals process. No number to call. Trying to sign in to your Google account yields an error and all of your connected devices are signed out. All of your Google data, your photos, emails, contacts, calendars, purchased movies and TV shows. All gone.

I nearly had a heart attack, until I saw that the Google account that had been suspended was in fact not my main personal Google account, but a throwaway Gmail account that I created years prior for a project. I hadn’t touched the other account since creation and forgot it existed. Apparently my personal Gmail was listed as the recovery address for the throwaway account and that’s why I received the termination email.

Although I was able to breathe a sigh of relief this time, the email was wake up call. I was forced to critically reevaluate my dependence on a single company for all the tech products and services in my life.

I found myself to be a frog in a heating pot of water and I made the decision that I was going to jump out.

Leaving Google

Today there are plenty of lists on the internet providing alternatives to Google services such as this and this. Although the “DeGoogle” movement was still in its infancy when I was making the move.

The first Google service I decided to drop was Gmail, the heart of my online identity. I migrated to Fastmail with my own domain in case I needed to move again (hint: glad I did, now I self host my email). Fastmail also provided calendar and contacts solutions so that took care of leaving Google Calendar and Contacts.

Here are some other alternatives that I moved to:

Gmail → Fastmail → Self-hosted (via Cloudron)
Google Contacts → FastmailNextcloud Contacts
Google Calendar → FastmailNextcloud Calendar
Google Search → BingDuckDuckGo
Google Maps → Bing MapsOpenStreetMaps and OsmAnd
Google Analytics → Matomo Analytics
Google Drive → Nextcloud Files
Google Photos → Nextcloud Files/Gallery
Google Docs → Collabora Office (Nextcloud integration) and LibreOffice
Google Play Music → Spotify / PlexSpotify / Jellyfin
Google Play Movies/TV → PlexJellyfin
Google Play Audiobooks/Books → Audible/Kindle
Google Play Store (apps) → F-Droid / Aurora Store
Google Android → Lineage OSUbuntu Touch on PinePhone (coming soon?)
Google’s Android Apps → Simple Mobile Tools
Google Chrome → Mozilla Firefox
Google Domains → Hover
Google Hangouts → Matrix and Nextcloud Talk
Google Allo → Signal
Google Podcasts → PocketCastsAntennaPod
Google Newsstand → RSS
Google Wallet → PayPal and Cash App
Google Voice →Ting Mobile

Migrating away from Google was not a fast or easy process. It took years to get where I am now and there are still several Google services that I depend on: YouTube and Google Home.

Eventually, my Google Home’s will grow old and become unsupported at which point hopefully the Mycroft devices have matured and become available for purchase. YouTube may never be replaced (although I do hope for projects like PeerTube to succeed) but I find the compromise of using only one or two Google services to be acceptable.

At this point losing my Google account due to a mistake in their machine learning would largely be inconsequential and my focus has shifted to leaving Amazon which I use for most of my shopping and cloud services.

The reason that I moved to mostly FOSS applications is that it seems to be the only software ecosystem where everything works seamlessly together and I don’t have to cede control to any single company. Alternatively I could have simply split my service usage up evenly across Google, Microsoft, Amazon, and Apple but I don’t feel that they would have worked as nicely together.

Overall I’m very happy with the open source ecosystem. I use Ubuntu with KDE on all of my computers and Android (no GApps) on my mobile phone. I’ve ordered the PinePhone “Brave Heart” and hope to one day be able to use it or one of its successors as a daily driver with Ubuntu Touch or Plasma Mobile.

I don’t want to give the impression that I exclusively use open source software either, I do use a number of proprietary apps including: Sublime Text, Typora, and Cloudron.

I guess that, for now, this is all the I/O I need on this machine. No shortage of of serial ports! My only complaint is that the on the multio card cannot be disabled (and takes priority over soundcard's) and has circuitry for just a single .

And for the final upgrade to my 486 ... 256kb of CPU cache!
The main board can go up to 512, but hey, I had these chips around and from 128 it's still a 100% increase :P
Look at them, snug in their new sockets! Ready for

Uhff, finally got the serial ports working on this PC104 386 board. There was a diode missing on the trace that brought the -12V to the RS232 transceivers.

This hacky monstrosity is a based on a 386SX CPU. It now runs . It's great if you need a small DOS based machine, pity the cases for this form factor are hard to find/expensive, and PC104 to ISA adapters are too! Will probably build a box with a few sheets of plexiglass...

I just love these retro devices. And it doesn't matter which company made them, they look all great. I miss that whole culture where you programmed a computer without distraction, studied a book with sprinkled in source code listings in 9-dot printer style, and did all that just for fun.

John Carmack is one of my youth heroes. Not only he invented and developed many of the techniques used by real-time 3D, he also took the time to explain them in clear articles and blogposts. He also ported all his games to Linux and released the full source code as GPL, a slap in the face to all the small-minded game firms who still regarded 3D engines as their most important trade secret.
