The heatsink cools the LM7805 power regulator, not the CPU. In the original 48k Spectrum, the heatsink was internal.

It already exists, though these guides are good to learn: LXC/LXD containers.

I have 2 issues with RCS:

1. Requires data connection, either WiFi or mobile data. SMS does not.

2. On Android, it goes through Google Messages. I don't trust Google.

So, I replaced Messages with another SMS app that doesn't spy on me and disabled RCS. If I wanted to do rich messaging through data connection, I would use Signal or similar.

So, RCS is not a replacement for SMS. It's just another IM protocol. And we have enough of those.

As for others replying through RCS, that's a failure of the messaging app, should recognize that the counterpart is SMS and reply in SMS. It's an attempt to force RCS...

SMS is for fast short messaging between mobile users, and that is its killer feature, it's universal. Every mobile phone supports it.

Signal dropping SMS support makes no difference for me, never used it for SMS, I used Signal for the secure conversations. Two different methods of contact.

This is interesting, but no mention of how the hosts process these molecules. We all know that our body has problems processing artificial molecules (artificial sweeteners, etc).

He mentions it shortly, in the Build Quality paragraph.

Nope, I tried everything, twisted the cables, etc. I even changed from power connector to another and changed SCSI cable. Outside it worked, inside didn't. Working perfectly outside, as soon it got close to the metal of the chassis it spun down, and as it got away from the metal it spun up.

My story:

In 1996 or 97, a friend brought me his Compaq Deskpro, the SCSI HDD had stopped working. No sound at all, dead. Tried everything, checked voltages, reconnected cables trying to clear any oxidation. Wouldn't spin at all. Well, called it a night.

Next day, decided to take it out of the chassis for a last test, connected outside. Not only it spun, it worked fine!!! WTH????

Well, into the chassis it went. Nothing. Dead. Whaa..??? Outside again, it worked. In the chassis, dead. Outside, worked. Scratched my head... With it working outside, just tried to place it on top of the chassis. It spun down and stopped. Took it away, it spun up. Got it close again to the chassis, it spun down again... Scratched my head again... Gave up, left it disconnected outside for the day.

Next day tried it again and this time it worked outside of and in the chassis... My thoughts? The chassis was magnetized or something...

Worked for a couple more years.

Do you know about dosdude's Catalina patcher? And for previous versions? It's unofficial, so it might not suit you at all. It allows older hardware to run (with some caveats) newer macOS versions.

Currently I have a 2009 MacBook Pro 5.1 running High Sierra.

The Atari ST line of computers also use DB-19 connectors for their external ACSI interface, usually used for connecting hard disk drives. ACSI is Atari Computer Systems Interface, similar to SCSI.

Someone managed to use them in a post below, I just copy-pasted them...

Portuguese name for quince is marmelo, hence marmelada.

Also, the husks and pits (what remains) of the quince are used to make a quince jelly, that we call "geleia de marmelo" (a liquid jelly):

In English you have jam and jelly; in Portuguese we have compota which is jam made from fruit pulp, geleia which is liquid jelly with a consistency of jam usually made with the rest of the fruit like husks and/or pits (though the name is also used for other products like bee's royal jelly), and gelatina which is the solidified jelly.

In portuguese, quince is named marmelo, hence marmelada.

Better than this only letting us download the savegames!

The biggest problem with full electric powertrains is size of batteries and its weight. Keeping the size of batteries small and weighing less is a bonus in ICE car conversions, like I mentioned in my initial comment. Plus better replenishing time, which in most hydrogen fuel cells cars is around 3 minutes.

Edit: the Riversimple Rasa uses a hybrid lithium based battery/supercapacitor pack for this purpose.

I would like to see an initiative like this but with hydrogen fuel cells. I think it would be more complex but more interesting in terms of: certifying road worthiness, since no more dealing with weight of batteries; no lithium-based batteries; more autonomy.

Despite being less efficient in terms of pure energy usage, I think hydrogen-based fuel cell-powered vehicules solve 2 problems for most users: autonomy and time of replenishment (refueling). We just need to invest in solar-based hydrogen generation plants. Hydrogen can be generated on site for replenishment.
