No, that is factually incorrect, hydrogen is not an "extremely potent" greenhouse gas in this context.

Hydrogen has a GWP of 11, meaning it is 11 times worse than emitting CO2. Methane, for example, has a GWP of 34, which is starting to get kind of bad, but "extremely potent" is something like SF6 wich has a GWP of 22800.

Furthermore, GWP is calculated on a mass basis, which skews things a lot for a light molecule like hydrogen.

I'm kind of astonished at the fear mongering on this issue, because it means people cannot be arsed to spend 20 minutes on Google with a calculator to check the numbers before they spread something as a truth. Let's do the actual math.

If you look at a Toyota Mirai, it needs 5 kg of hydrogen to get a 300 mile range. A comparable diesel car needs 28 kg diesel to get that range, and will emit 88 kg of CO2 when that diesel is burned (the O's in CO2 comes from the air).

Even if the hydrogen car had an absurdly high leakage rate of 50% during that trip and the period it stood still before next trip, it would still emit only the equivalent of 27.5 kg of CO2. So at insanely high leakage rate, diesel is still 3x worse than hydrogen.

If we are realistic about leakage rate, published numbers from actual measurements with the Toyota Mirai placed in a sealed container gives us 2 mL/min at 1 bar, so the time to leak the entire contents of the tank is more than 3000 days.

So let's say this is a hobby vehicle (like a small aircraft) seeing infrequent use, you consume two tanks of hydrogen per month. That puts your leakage rate at 0.5%, giving an emissions equivalent of 0.56 kg CO2, while the diesel (avgas) powered equivalent would emit 166 kg CO2 - 300x worse.

Note that this is all based on technology that is already here - you can go buy it today - not some hypothetical developments.

> I bought a 3 year old car because the new model only did climate control in the on-screen menu.

This complaint always feels so weird to me. I don’t love the initial experience of setting up climate control on a touch screen, but it’s literally something you only need to do once ever.

New cars aren’t like old cars, climate control is set and forget now. We’re far past the time of having to constantly adjust it in order to maintain your desired temperature.
We are discussing this at the place I work at the moment.

There is something I've never known the answer to, perhaps someone here who knows more about incidents can help.

I have joined a small team. There are perhaps 2-3 devs who can actually fix issues. There are lots of issues, e.g. one incident a week. We're obviously trying to fix the software but every time something goes wrong it's a new problem. We have 100+ microservices interacting and 1k req/second, on a 20-year old codebase where most of the services are written by people who are no longer at the company, so although we're trying and making improvements, and I'm doing my best to help, it's not going to happen overnight.

Which brings us back to incident support. We're too small a team to have an on-call rota (i.e. with 3 people everyone would have to be on call once every 3 nights, apart from when people are on vacation or sick when the remaining people would have to be on-call more). So the management's idea is just that everyone have slack on their phone and whoever is available jumps in either when an alert goes off, or when someone (e.g. support) writes something isn't working. "Professional jobs aren't just 9-5, they do involve overtime sometimes". To be this just feels like being permanently on-call, which I don't want (burnout risk etc.). It might be different if there was an incident once a year but it's much more frequent than that.

So I know what I think we shouldn't do, but what should I advise the company that we should do?

We can't fix all the issues overnight, every incident seems different, we have too few people to have a rota, the software is too complex to outside operations to an external team (e.g. last fix last night was for one of my colleagues to deploy a quick hack to the codebase to turn off one feature, then build the code and deploy it), yet it's a international consumer website that should be available 24/7.

How are they supposed to do that when a rich person A who earns more than he spends accumulates ever greater amounts of gold, leaving everyone else who wants to trade and don't care about trading with A stranded.

Think about it this way. Germany keeps saving more euros. Greece and Spain are trading with each other. At some point all the money is in Germany, making it impossible for Spain and Greece to trade with each other even though they would have maintained balanced trade between each other. Greeks can't buy the latest gadgets produced in Spain even if they wanted to.

I’ve arrived at similar conclusions and it seems roughly inline with research on gut biomes. My own autoimmune condition began after a stressful period with a negative emotional aspect. I’d also been eating less “healthy diet too”, etc.

The first line is vit-d and pro-biotics, especially if you have heavy inflammation and microbiome issue or have taken antibiotics.

Alongside those would be eating a generally “higher quality diet” with a fair bit of variety. Reducing sugar and avoiding highly processed foods and preservatives helps significantly. Foods with less antibiotics help too, so items like free range eggs, organic milk can be helpful. Vegetables seem less affected by organic or non-organic.

Fermented foods are pretty important in providing a wide variety of microbes. I’ve noticed that lots of traditional spices like turmeric or black pepper are beneficial. I have a pet hypothesis that most “traditional diets” in a region would adjust to include useful spices and come to “taste good”. Almost every regional cuisine also used to have a staple fermented food. Nowadays fermented foods are generally replaced by vinegar substitutes nowadays (sauerkraut, pickles, Kim chi). Ketchup has roots as a fermented chutney like tomato sauce for example. Obviously kefir and such are different.

Going more keto or alternatively vegetarian doesn’t matter as much once your gut biome can shift. Though often going keto or vegetarian tends to get people to start eating better quality food. It also encourages a wider variety of foods which help prevent mono-cultures forming in the gut microbiome.

However good food isn’t a cure all, just a helper too keep the microbiome healthy. It can reduce chronic inflammation alongside vit-d.

Physicist: And your courses in physics…

Me: They ended at thermodynamics. I couldn’t handle PDEs.

Physicist: What are the units of h-bar?

Me: Uhh, well, it’s a conversion factor between energy and time. (*)

Physicist: Good. What’s the radius of the hydrogen atom?

Me: Uhh … not sure … maybe something like 10-15 meters?

Physicist: OK fine, he’s not one of us.
Same here in the UK, if you scheduled a meeting at 5pm on most days people would be pissed by on a Friday of all days you'd make a lot of enemies.

My old job where I was last on call did Tuesday - Tuesday with a 1pm handover. It gave you time to deal with any issues that were still hanging around from the weekend but then you were done. Handover was happily during the work day so it could be moved back or forth a bit if needed and the new person on call had a couple hours to ask extra questions if needed.
Which means you wouldn't bother trying to mine a block. Seeing that no one is bothering to try to mine a block--and so their transactions are taking forever to complete--people would increase the fees they are putting on their transactions (which doesn't even require them to know what is going on, as that's what they would presumably try to do anyway) and eventually enough high-value transactions would exist to make it worth trying to mine a block with them included.
Also note that he has become very involved in research into physics (and stem) education in the later parts of his career (and has done some interesting stuff in this space as well).
I don't disagree with your points, and having worked at both massive IT organisations, tiny startups and scale-ups in-between, it's clear that different organisations need different levels of rigour and process!

I see the guide less as a set of dogmatic rules to follow, and more of:
a) a set of sensible defaults for small to medium size orgs who are starting with little-to-no process
and
b) a source of inspiration for larger folks who maybe want to bring their processes out of the ITIL ages and into a world that's a little more applicable to the way folks work today.

As you say, the extremes of the ITIL <---> Agile spectrum is likely to be a mess, and where you should target on that spectrum is highly dependent on your starting point, your culture, and your appetite for change :)
How about instead of enforcing your authoritarian money model which puts all the power in the hands of financial capitalists you instead abandon the idea of caring about the interests of the financial capitalists and just let people trad with each other without requiring permission from authoritarians?

It is really quite strange that one would consider the gold standard a source of liberty. Humans aren't made out of gold. They die at some point, creating an obligation that outlasts a human life is honestly sickening and perhaps worse than slavery.
Gold isn't valued by its industrial uses. That's why gold is good as a currency, precisely because it has very limit use. With actual use comes demand based on that use, and that demand causes swings in value - what you don't want for a monetary yardstick.

Gold is gold because it is useless and also rare. And can't be produced. And spread widely. All these little features are its value because they are what you want in a currency. And the good currencies try to replicate that. It its perfect in this regard, but closer than any other phsyical item.

BTC has some of these and its properties are still in flux. And BTC is only part of the cryptofx world might wind up being the same thing financially.

An oral history of Harry Potter at 25
I'm not talking about covid; covid is not covering the planet. I'm talking about life in general.

All that oxygen comes from all the plants.

Yes, life has so far only covered the top of the planet. You are right that a paper clip maximizer would need quite a bit of time to go deeper than life has gone (if it would get there at all).

> And a paperclip factory isn't self-reproducing [...]

Why wouldn't it? If your hypothetical superhuman AGI determined that becoming self-reproducing would be the right thing to do, presumably it would do that.

No perfection required for that. Biological machines aren't perfect either. Just good enough.

You are right that thermodynamics puts a limit on how fast anything can transform the planet into paperclips or grey goo.

Though the limit is probably mostly about waste heat, not necessarily about available energy:

There's enough hydrogen around that an AGI that figured out nuclear fusion would have all the energy it needs. But on a planet wide basis, there's no way to dissipate waste heat faster than via radiation into space.

(Assuming currently known physics, but allowing for advances in technology and engineering.)

---

Of course, when we worry about paperclip maximisers, it's bad enough when they turn the whole biosphere into paperclips. Noticing that they'll have a hard time turning the rest of the earth into paperclips would be scant consolation for humanity.

(But the thermodynamic limits on waste heat still apply even when just turning the biosphere into paperclips.)
Ultimately the claim is computation = things = humans. If everything is a computation then humans have no more value or uniqueness than a thunderstorm. This is sinister and pernicious.

1) We can & should differentiate between different classes of things like life, intelligent life and physical processes. This stops us from being cruel to things that experience suffering.

2) We may not be able to perceive or adequately describe classes of non computational processes that operate in our physical universe. This would not be a shock, after all, dogs can't do relativity and yet that does not exempt them from living in space time. Yet, we know that non computational processes do exist in theory. The claim "everything in the universe is a computer" is just that - a claim. It's up to people who believe it to show that every physical process that there is can be replicated using a computer... and that's not been done. To do it you need to enumerate the processes (which requires a competent theory of physics - not one that can't describe 98% of observed things), and you need to show that they can all be computed. We can't do the second thing because we can't even write down descriptions of intelligence and consciousness let alone compute them.

So, dangerous and unfounded. Dislike.
I think they're competing forces.

There is periodic pressure to return to [greater] profitability, at which times companies fire like mad. Either it's a higher level of management realizing one branch of the org chart is stupid and directing its removal, or a directive from the top "figure out how to cull 10% of the workforce".

Between those events, however, managerial accumulation of influence takes over.

Maybe c-suite execs don't rip out excess staffing immediately because, even operationally, it's not all downside:

Within a relatively small branch of the org chart, having more than bare minimum staffing (with some of them doing bullshit jobs) provides a human resource buffer that might be tasked with solving really important problems that crop up sometimes: significant new requirements from a customer, or, if the incentives are right, opportunistically solving non-critical persistent problems (e.g. refactoring more) or automating more. I guess there's not enough pressure from higher management to keep teams to true personnel requirements + a few extra, so the "few extra" grows like mad.

Within a larger branch, occasionally having "excess" staffing for internal corporate competition is good. One of the best strategies for large projects (like larger government contractors) is to run two teams each with half the budget and select the best result. It seems insane from a naive perspective: wouldn't it cost nearly twice as much to have double the headcount? But it doesn't seem to, especially when the vast majority of project costs are labor costs or linearly related to staffing (rather than external resource costs, which are more static—though even for resource-intensive projects, internal competition provides incentive to figure out how to use less resources).
There is no such relation.

You can save cash which does not result in additional investment. When banks refuse to lend money, saving does not result in additional investment, in fact that is the cause of QE. The government feeling compelled to invest because people in the private economy refused to invest.

The UI part is not the issue, if you decide to use Qt you still need to do your "business" logic in c++ , then eventually you get some memory leak and have to setup tools to investigate what is the issue.

What would be a great feature for Qt is to have a way to make the GUI with QML but implement your actual work in C#,python,Java. So you would need a way to connect the GUI with data types and functions from this languages.

I remember Qt company tried at one point to offer Java,C#, Python official bindings but that effort failed, is probably hard.

Maybe an alternative to electron would be a JVM based modern GUI framework, something maybe inspired from the best parts of WPF, MXML and QML. And I am thinking JVM because you have access to Java's big standard library to do desktop like things like file,network IO and also have access to the native OS if needed.
I think you are conflating different concepts. It is clearly imaginable that a very intelligent agent could end humanity if its objective would require so. How exactly is "perpetual motion machines can't exist" related to this? How is it going to prevent an agent from engineering 1000 pandemic viruses at the same time?
Yeah, thanks for the conversation. You've definitely made me think about some interesting things. Yeah, if I were to say more, it might just be repetitive.
Sounds like the competence of an average senior manager.
Similarly the 87% is impressive, but that translates to a difference of "only" 9 dB. The way our ears work makes me wonder if that is enough to make a difference for noise reduction (my earplugs say on the package they reduce sound by 32 dB, for example)

edit: of course, worst case it would still contribute passively to noise reduction

> ToLookup, especially ToLookup, a lot of C# developers sleep on that ... and you have to search NuGet for a mutable ILookup<T> implementation

Interesting. I have recently replaced a List<int> with Hashset<int>
This is a (IMHO, underused) part of the standard library https://docs.microsoft.com/en-us/dotnet/api/system.collectio...

C# Devs tend to know List<T>, Dictionary<K, V> but not HashSet<T>.

The reason for that replacement was simply: "we have a lot of 'business category ids' in this opt-in list, all we do is ask 'is the current id in the opt-in list or not?' so duplicates have no meaning, and ordering is possible but of secondary importance ... that's mathematically speaking, a 'Set' not a 'List'. "

So using Hashset reduces the check time from O(n) to O(1) and otherwise it's pretty much a drop-in replacement: Same initialiser, same 'Add' and 'Contains' methods, also found in 'System.Collections.Generic'.

I'm looking at ILookup<K, V> and it looks fairly similar to Dictionary<K, IEnumerable<V>>

I fear it is the same with anyone who mentions “ISO compliance” and how we will “fail our audit if you get caught” as a reason not to do something.

I have never seen these prognostications come true. It really seems like it’s just a way for naysayers to rain on peoples parades, or appeal to authority as an way of stopping people from doing things when really they just don’t like them.

It leaves an extremely unpleasant taste in the mouth and it’s an absolute must to probe this kind of thing when interviewing candidates.
