I was thinking that the writing is upside down. Very wrong IMHO to write on a floppy disk that way.

A Bitcoin mining node is the simplest possible way to turn compute into money. Very minimal storage and bandwidth requirements. And yet we still do not see those in houses.

Everything about doing productive computing tasks in houses is more complicated than that! At least it is more profitable, I think?

(I wonder what a rough profit per watt figure is for a datacenter. Very much "it depends" I'm sure.)

A half rack in a rack of last decade is 8kw. A half rack of today's state of the art is 100kw.

A house older than 30 years typically has 100A 120V split phase power which can supply 25000 watts (you wouldn't want to ever fully load it...)

And an 8000 watt space heater will definitely be noisy, and produce too much heat for pretty much any house.

(Have 3yo and 1yo, another one the way, goal is 4)

I have often thought that car seats are one of the major drags of modern parenting. This study apparently (I don't have time to read it, too busy with kids lmao!) confirms my suspicions.

It is unfortunate that every policy change around them is trading some amount of convenience for every smaller risk eliminations. It is essentially impossible to say perfectly rational things like "I think children should be put in this slightly riskier type of car seat for convenience reasons."

Even if laws are relaxed, there is the peer/manufacturer pressure. As a real example, I think it is pretty annoying to have my three year old facing backwards. It would be somewhat more dangerous to have them facing forwards, but a substantial improvement in quality of life for me and for the child. The manufacturers compete based on max weight that they support/allow/claim for rear facing, something like 45 pounds. So a family member such as a spouse allegedly has decided that the child ABSOLUTELY needs to be rear facing until they reach that weight. That may not happen until age five! By this time there may be manufacturers inching up to 60 pounds rear facing.

The only possible relief I can envision is that computers become so proficient at driving our cars that there are essentially no accidents. Then we may be allowed to sit unbuckled holding our children!

This is so bad that it must be intentional, right? Even though these are dirt cheap, they couldn't come up with $100,000 to check for run-of-the-mill vulnerabilities? There must be many millions sold. Quite handy for some intel agencies.

I assume any Wi-Fi camera under $150 has basically the same problems. I guess the only way to run a security camera where you don't have Ethernet is to use a non-proprietary Wi-Fi <-> 1000BASE-T adapter. Probably only something homebuilt based on a single board computer and running basically stock Linux/BSD meets that requirement.

Scott Locklin is one of my favorite reads, in occasional doses though. Kind of unhinged-seeming but always some perspective that seems fresh.

He's like Casey Handmer turned up to 11, and throw in a use of the word "retarded" in pretty much every post which surely is some repellent just to make certain types of people go away.

Actually I'm not sure I really get anything out of reading either of them but they provide some enjoyment and glimpse of a possible future.

Search Amazon for "pfsense mini pc". (smile as you think about how this triggers that one pfsense guy!) Intel N100 or N150 processor, passive cooling, typically 5 1000GBASE-T or better ports, RAM and SSD included. Should be able to get one for ~$200.

The UI for the fs.com programmer is merely "not bad". This could easily be great in comparison.

Fun fact: each one also consumes approximately $4 in electricity per year.

Assuming 2.5W typical consumption, $0.18/kWh rate. More like $8/year if you are in a high rate area!

You can put multiple IPs on a computer. (Or VMs, LXCs, etc. which would each get an IP)

Now what size of machine?

(I don't really care, and the original question does have a whiff of malicious intent, but scaling discussions are sometimes interesting...)

The advertisers can see the traffic coming in from clicks, I would think. There would remain some opportunity for fraud by FB if some of the ad money is just for impressions but it seems like it would be difficult to keep click rate up while shorting the buyer on impressions.
