Once you get into closed loop PWRs the numbers get crazy. Actual figures for Naval Nuclear plants are classified, but as a nice round number example if you pressurize the secondary loop to 250psi you end up with about 1,725 kJ/kilogram to boil it.

Absolutely terrifying stuff.

In my experience we saw some losses when taken as a system that prevented us from hitting 2:1, but they weren't anywhere near 50%. We also ran closer to 40% than 33% thermal efficiency in the power generating loop, so many of the system thermal costs are baked into that 33% efficiency to the grid.

Basically, each reactor install will have it's own minor issues. Overall they should be hitting around 2:1 as an entire system. If they aren't there is something going on that I haven't come into contact with (which is quite a lot, I'm sure).

Much like the author however, I found that my natural curiosity, and specifically that desire to ask what the words being used MEANT, to serve me extremely well. When I was a PM for a billion dollar plus project (military can hit that easily) that attitude is what got me the job.

The constant push back from those who seem to value only their, and your, positions as cogs in a machine was exhausting. I really agree with this entire article. Thanks for posting it.

The commenter didn't even have the curiosity to read and comprehend the article, and made the articles point in that.

I don't see the point personally. I'm just aware of the arguments. The "best" use case I saw was some hunting and lake cabins extending coverage.

In HAM circles some people do use WiFi in an arguably legal manner by making the SSID their callsign and either making the network open or putting the password somewhere public. This is because you are not allowed to use public bands for encrypted communications (with a carveout for satellite control, for obvious reasons).

I'm unsure what ranges can be hit with that setup, but I know it can be far enough that LoS due to curvature of the earth becomes a factor.

I do think just getting a wireless P2P bridge is easier and smarter and why this hasn't seen more use.

Extreme contention when 250 people had 3 APs as their only connection and half were trying to play WoW at the same time.

Nuclear discharges more like 2kWh of heat per kWh of electricity produced.

Perhaps slightly more, but its in that ballpark. Seems like a small difference but you are overstating the waste by near 50%.

Source: Degree in Nuclear Engineering, previous life was a Reactor Operator. Also, just look up thermal efficiency of currently operating reactors.

Speeds aren't any better, but at least it was cheap and fiber.

ConnectX-4 and newer are natively supported. I use a ConnectX-4 LX in a $50 Razer CoreX off of craigslist. Works fine, hit similar limits to what Jeff did.

Using an OCP is the neat trick here. MUCH smaller setup.

As far as the other posters comment about Tx's... that is an entirely different topic. I've never had an issue with FS.com optics personally.

The new one (EZY) is amazing if you haven't seen it.

How do you tell if someone is driving drunk?

They are driving straight!

With the unspoken part being anyone NOT drunk was weaving to dodge debris, potholes, etc.

Why are you throwing in extra cost for something thats not necessary? I know multiple people with 128GB Macs and none of us upgraded the storage. Especially not on a Studio (which isn't currently available).

I will say that their $3k number is off. I somehow missed that, and its too low.

Even a 128GB is $6.8k today. Still only 2/3 your quote.

Bandwidth is relevant (I have both a 5090 and an M4 Max 128GB Studio, so have direct comparison right here), but quote the cost appropriately!

Instead we are focused on investing our money as a form of self-insurance.

It's kind of like life insurance; term makes sense but whole life doesn't (vs investing the premiums).

As far as polymarket: I can't say there. I've never used it (though I know what it is).

I was writing a program to do some remote drive upkeep and realized I needed permissions I didn't have, but could use a built in tool to do them. Then realized that meant I could take another step and use a human interface issue to gain more privilege if I wanted to.

Built a proof of concept on my personal machine at home, checked that it worked, reported it upline.

I never executed that code on our work systems and would have ended up in jail if I had. But even writing it nearly landed me there.

Absolutely awful timeline where the value of a PC goes up with time.

I didn't toss those there because those (and IDEs and SSH/Terminal clients) are very opinionated and everyone has their favorites.
