Since they’re robots, automated tests and manual tests are effectively the same thing.
I'd buttress this statement with a nuance. Automated tests typically run in their entirety, usually by a well-known command like cargo test or at least by the CI tools. Manual tests are often skipped because the test seems to be far away from the code being changed.
My all-time favorite team had a rule that your code didn't exist if it didn't have automated tests to "defend" it. If it didn't, it was OK, or at least not surprising, for someone else to break or refactor it out of existence (not maliciously, of course).
I fear that this would lead to everyone being allowed exactly one account -- why would you need more than one if the one you have can never be fully deactivated? -- and that account would be tied to your human identity forever. Which would go about as well as any other attempt to solve Sybil problems.
My dad has been telling the same story for ten years. He wants to take a trip around US national parks, sleeping in the back of the car, under the stars, which is why his car needs a 500-mile range and must be fueled by gasoline. This conversation always comes up at family gatherings when he asks how I like my electric car.
He's in his mid-80s with prostate problems. He has never taken the trip.
There is now an even easier way than vacuuming. Instead of pulling the unwanted air and moisture from the lines, you can push it out with another gas, which itself can somehow coexist with the refrigerant. I haven't tried it because I already have the pump and gauges, but if I were installing my first mini split, I'd consider it.
It's so ridiculously easy to vacuum and charge a heat pump it's kind of unnecessary.
I think I spent $200 in parts on Amazon and have done 4 heat pumps now. It's a vacuum pump, a scale, and a digital manifold/guage. Punch the numbers for subcool/superheat into a calculator and use the temp probes on the lines where they connect to the condenser and you can even skip the scale.
Isn't the problem having access to the gas in the end ?
They are tightly regulated, and this is why installers can charge a lot of money, I believe.
How did you manage to locate a source?
For a typical new install, the outdoor unit contains the charge and unless your lineset is unusually long, you just use that, releasing it with the valves after installing and leak-checking the lines.
In the US, you can get your EPA 508 cert online in a couple hours and buy the refrigerant online. (You need the cert to be legal, but it’s not really checked just to buy.) Tightly regulated is not true in practice. You could buy some in 3 minutes online and have it Monday.
Yes, in the US I think it's fine; you have a lot more freedom.
In France, access to the gas technically requires a certification that is not available to regular people. You need to be professional and bow to the bureaucracy.
I know somebody who was required to pay the full installation price for a heat pump he installed himself because there was no professional that was willing to charge and launch the installation for the small fee it should require.
This is the hypocrisy and value-destroying behavior of EU collectivist governments. They tout ecological solutions, but you need to pay far more than is reasonable for those modern solutions. Predictably, people chose things that are worse but cheaper, like wood-burning stoves or pellet stoves.
Those things are made artificially expensive for no good reason, and that's because they get built overseas mostly, and this happened because of regulations in the first place.
Then they wonder why the EU is losing ground economically…
For your friend’s new install, the refrigerant was in the outdoor unit when shipped from the factory. Accessing that gas just takes an ordinary hex key/Allen wrench. Only if they’d made a mistake and let the refrigerant leak out (or had a ridiculously uncommon length of lineset) would they need access to additional refrigerant.
Yeah, I know they come pre-charged now. But I can't remember what his problem was back then. Maybe he didn't know, or he fucked up…
From what I understand, self-install should be fine up to a 12m run, but if you let too much gas leak, you may have issues because of low pressure.
At least now you can buy them for relatively cheap. Mine required a swap of the control board on the inside unit, and it was ridiculously expensive (almost as much as buying a new unit).
I am not sure why it fried, but probably bad solder from old age (it's about 15 years old at this point).
It's an excellent technology, but the surrounding business feels extremely shady.
Home electricity in California is about 45¢/kWh. If your F150 mileage is typical, you're getting about 2 miles per kWh. 600 miles would cost about $135 here in California. Meanwhile, a 20 mpg gas car would cost about $110/month at $3.65/gallon.
You must be paying about 4.7 cents per kWh, or about 90% less than you'd pay here.
I'm reminded of Larry Wall's advice that programs should be "strict in what they emit, and liberal in what they accept." Which, to the extent the world follows this philosophy, has caused no end of misery. Scrapers are just recognizing reality and being liberal in what they accept.
Or when the site tells you your store doesn't have a part in stock, but neglects to tell you that they do have 350 of the identical part, different brand, in stock. Because who would ever buy a 1/2-inch close Halex rigid conduit close nipple in-store right now when they could wait a few days for a 1/2-inch close Commercial Electric rigid conduit nipple?
Agreed. I'm working on a small GUI that just appends to a local .ndjson file. A user just posts with a text box into a feed. Like a one person chat or tweeting into the void. And a local LLM picks apart metadata, storing just enough to index where answers to future questions will be. Then you can use slash commands to get at the analysis like "/tasks last month" or "/summarize work today" etc.
Not sure why you're getting downvoted, but I agree at least in principle. There should be some means to index/search this kind of semi-structured text. Summaries are also nice, but not as useful to me at least.
Like the author I also do tagging, but in the real world some notes will eventually slip through the cracks. Even when it's just one, that's probably the one you're looking for. :)
