  • Yes. You are always adding net energy to the system. That’s why a heater is a self-contained unit (turns energy into heat) while an air conditioner requires two units- one to suck up the heat outside, another to reject that heat outside. It’s not ‘creating cold’, it’s using energy to pump heat from the inside to the outside. The total amount of heat rejected outside is a net addition- it’s the heat sucked up from inside, plus the waste heat from the compressor.

    The air conditioner (current design) works on the simple principle that the boiling point of a liquid changes based on ambient pressure, and that phase change (between liquid and gas) carries a lot of latent energy. To boil water with heat alone, it takes about 100 calories to heat a gram of water from just above freezing to just below boiling. But to boil it, to heat it less than one more degree and turn it into gas, takes another 433 calories. That means if you adjust its boiling point by pressurizing and depressurizing it, whenever it boils or condenses it’ll suck up or release a lot of heat at the same time.

    Obviously we want colder than 100c, so we use a refrigerant like tetrafluoroethane with a boiling point of -26c.

    This gadget uses a similar concept. Instead of using pressure to tweak the boiling point of a refrigerant, it uses a solid that heats or cools in response to pressure. Then water carries the heat around.


  • Yes but China, Russia, Iran, etc all have national-level firewalls in place. You can go in China and chances are your VPN won’t work, and if it does the whole country is fucking network-hostile (like I’ve seen reports of the USB charger ports in hotels trying to hack into phones).
    UK, as far as I know, doesn’t have any kind of similar national level firewall. Nor does USA or most other ‘civilized’ nations.

    And without that national firewall, all these laws are crap. Because unless you’re physically prevented by the firewall from downloading or using VPNs or similar tools, all the laws in the world are just a padlock on a cardboard box.



  • The problem is that the internet is fucking global. As long as that is the case, it is simply not possible to fix this problem.

    You can put whatever regulations you want on online content, and some provider from a different jurisdiction is going to say screw you I abide by the laws of my own jurisdiction. The restricted citizens will use that company.

    It is like making drugs illegal when there is still an illegal drug dispenser in every home. It doesn’t work.

    The most you can do is try to block this at the payment level, but that requires setting up a very intrusive payment blacklist or whitelist system. And then some VPN provider will just make themselves ad supported and you are back at square one.

    And that doesn’t even touch the issue of torrents, p2p file sharing, and decentralized networks. Go back to the early to mid-200s and everybody used those things because most of the content they wanted wasn’t easily available legally. Then it became easily available and people started paying for it. But you throw enough roadblocks, make people subscribe to too many streaming services, require too much age verification type crap, and the world will sail the high seas once again.





  • Look at the wording- ‘premium experience’. He’s not selling coffee, he’s thinking big picture of the whole experience from the moment you walk in the store. He’s not even wrong here. This is good business management- that he’s taking charge of everything about the store from the decor, the furniture, the colors, how the employee talks to you, etc. That’s all part of the experience.

    What’s wrong is that people keep going. Most people don’t give a fuck about the experience, they just want a tasty coffee. Our economy is based on competition and free choice. If he makes his coffee cost $8 or $9 or $15 or $50 that’s his right and his company’s right. Just as it is your right to go elsewhere, which you should be doing anyway.

    The thing is- IMHO, Starbucks coffee isn’t worth anywhere near $9. Here’s a challenge- go to Starbucks and order a double espresso shot. Now find a local artisan coffee place, like the type with a chalkboard that says where the beans they’re brewing today were grown. And get a double espresso from them also. Compare the two.
    What you’ll notice about Starbucks is that it’s burnt. And that’s because it’s literally burnt- the typical Starbucks bean is roasted MUCH darker than average, so the resulting coffee flavor is dominated by a burned smoky bitter-ish flavor.
    Compare that to your local artisan coffee place- you’ll notice it’s NOT burnt, the flavor is NOT dominated by smokiness, but you have a lot more layers of flavor. Then order whatever drink you want- better coffee in means better drink out.

    Keep in mind also most of what Starbucks sells isn’t really coffee, it’s milky sugary drinks that incorporate a few drips of espresso. So you’re paying $9 for a sugary calorie bomb made from overly roasted coffee that just makes you fat.


    Also- if you usually order the same thing at Starbucks- just learn to make it. Even if you throw $1000 at a nice fully automatic espresso machine, taking the per-coffee cost from $9 to $1 means you’ll break even on the machine in 125 coffees. For most people that’s less than a year. And you can do it yourself- next time you order, watch what the barista does. They are not wizards and nothing behind the counter is magic. An espresso machine and a blender will make like 95% of the menu. Here’s a guide





  • The problem is it’s not just ‘form a union’. In most cases unionizing means joining a much larger union that covers many hundreds of companies. And it will mean that all questions of compensation or discipline then have to go through a union contract. It means more paperwork and less flexibility.

    If there is trust between workers and management, then workers often don’t see much benefit to going through all this. And that’s why the guy said every shop that went Union deserved it, because those shots all tried to save money by screwing their employees and so the employees fought back and unionized which ended up costing the company more than if they had just paid the workers correctly in the first place.


  • In most cases here unions are fairly large organizations where the larger union covers dozens or hundreds of companies. So it wouldn’t be like ‘Bob’s maintenance shop union’ it would be like ‘international brotherhood of machinists union chapter #1234’.

    And when that is done, the relationship between the workers and the company changes. The union will negotiate a specific contract with the company which all workers and all jobs then are covered under. This provides a lot stronger protections for the workers, but can also be less flexible in some cases. And of course the worker has to pay dues to the union, it’s usually not that much but it’s not zero.

    Point is, if the workers are happy and have good relations with management then they often see no reason to go through all this.

    On the other hand when management starts turning the screws and tries to make more profit out of the worker compensation, then it’s absolutely time to unionize and workers are even more seeing that.


  • I once was on a tour of a non union maintenance shop, in an area where most similar shops were union. One of the people on the tour asked the manager about this.

    His answer- ‘Every shop around here that’s gone union, has deserved it. I pay my guys above average, I don’t flip out when they take time off, and we have decent health insurance. My workers are happy- when the union comes calling it’s the workers who tell them to get lost.’

    If WotC is going union, they probably deserve it.


  • The name has been there for almost 20 years. If harm was going to happen, it would have already happened, would already be happening.

    Consider drugs- if I invent a new drug, I have to run studies to ensure it’s not harmful. But if the drug’s been on the market for 20 years with many millions of doses consumed, I can look at the people who’ve taken it to see if it’s harmful.

    What you’re saying is the drug’s been on the market for 20 years, there’s no reported harm in that time, but we should pull it off the market anyway. That makes no sense.

    Can you find one single person anywhere at all who’s said ‘I’m disabled and the name GIMP is offensive’? Surely if the name hasn’t caused offense in the last two decades, it’s unlikely to cause offense in the next two decades?


  • You misunderstand me.

    If someone with a physical impairment says that using this word in software is harmful TO THEM, I will ABSOLUTELY believe them at face value and probably agree with the name change.

    Can you find me such a person? THAT is what I was saying in my post. I don’t see any evidence of actual offense happening. I see people trying to avoid offense, but no actual disabled people taking offense.


  • You want documentation that gimp is offensive?

    ‘Gimp’ as referring to someone with a disability, is offensive. That’s not the only use of the word.

    Or are you on the camp that we should rename IDE connections ‘master’ and ‘slave’ because a dark-skinned person might have a problem with that?

    Pretending to not understand when an acronym spells a word

    I understand exactly what it means. I am pointing out that it has more than one meaning.

    The point of my original comment (which you apparently missed) was that GIMP has been called GIMP for years/decades… if in that time nobody has actually been offended by the name, then why is it important to change it now?

    Let me give you an example- let’s say I make a piece of software called Web Output Parser, or WOP. Obviously ‘wop’ is a potentially offensive term, as it was once a slur that refers to people of Italian descent.
    If my WEb Output Parser is used by millions over 15+ years, and not one single Italian-descent person reports offense, am I under some obligation to change the name to avoid a future offense that hasn’t occurred in almost two decades? Does the fact that the pejorative use of the word has gone out of common vocabulary make any difference?

    That’s why I say it’s performant. Renaming GIMP would cause a problem for millions of people who use, modify, and distribute GIMP, all to avoid an offense that hasn’t happened in almost 20 years.
