Liquid nitrogen is a byproduct? I thought it is normal commercial product. It can be produced with liquid oxygen, but don't they use LN to recover energy used to freeze air? Not reusing LN and just dumping it would be like wasting 80% of energy.

> Owners will typically have to replace the nitrogen every seven to 10 days, depending how much they use it.

100L tank of LN "soaks up" about 8kWh of energy when heating from liquid to -10C, so like a heat pump transferring 200W for 5h/day for 8 days. Not that much. 100L of LN costs about $3000 where I live, 8kWh of electricity costs about $2, no one sane would use LN2 instead of electricity.
You cannot seriously believe that GitLab is a decade long bait-and-switch tactic.

If it was done in a year or immediately after gaining huge momentum, then sure we'll listen, but again, GitHub has been around for so long that it's clear they simply couldn't predict the growth and handle the increase in cost.
This was a refreshing read, and a solid reminder.

I'm working through an executive communication pickle as I write this. My (startup) CEO is a slide perfectionist who never likes any deck he sees the first time. And he's critical of decks in subsequent passes as well. I'm responsible for revising our company pitch deck with "fresh eyes" as I'm relatively new to the company.

Have had to remind myself multiple times that his feedback is not bad, or wrong, or too critical, at least not 100% of the time. And instead that I should reason through how to integrate that feedback or find a way to meet somewhere in the middle while properly describing why I am choosing a different path.

The learning process never ends!
I’ve come across my company’s logo used like this a few times before on startup sites. It made me curious and would ask around if anyone had ever heard of or used said startup. In most cases no one had ever heard of the startup or they were commissioned for some small project that never went anywhere. No one seemed to care though that the logo was being used. I would take those logo lists with a grain of salt.
I looked at some of those. I find plenty of cases where someone had a broken meter, was undercharged, then was charged to catch up. The electric company allows them to pay over time if needed in all cases.

I looked through New Orleans rates. They never doubled.

I find zero cases where the electric rates doubled, which is what the person here claimed.

As far as complaints, I can find people here complaining their rates doubled, when in fact they did not. Going to another place is not much different than here.

As far as I have found, no electric company doubled rates, contrary to lots of hearsay.

Maybe this is just because leadership is hard, and more people are needed in leadership positions than are capable of fulfilling the role?
Sadly melodramatic. If anyone needs sacked, it's half the executives in the US. I witnessed one sobbing publicly on stage at GE about his diversity program--while parading his hand-picked brown people around on stage. It has gotten out of hand.
The raw heat output of humanity divided by area of earth.

GHG is bad because it produces single digit watts of forcing (captured solar heat that would otherwise escape).

Direct thermal forcing from either capturing sunlight (making the surface darker) or emitting heat from nuclear derived (or in short term, fossil fuels before they run out) sources is just as catastrophic, but further off.

We can happily replace our current energy needs with nuclear and renewable, but we're just back at square one if we don't end growth.
While good advice for persuading someone 1-1, and I also highly recommend Chris Voss. I'm not quite sure that's what OP asked here.

No one is saying 'don't make money'.

I'm just saying, this is a commercial relationship.

When my bank raises it's fee's I complain, but I probably won't move bank.

When I go get a coffee and they're like, 'sorry, to cover our costs the coffee is 50c more', I'm like... eh; we have a friendly relationship and I'll just wear it.

...but, and here's the thing:

If I went to get a coffee, and they were like, sorry, you have pay an extra $5 for the sugar; you think it's unreasonable and entitled to complain about that? After all the years of free sugar, surely I should just support them in these times and pay and extra $5 for the sugar on my coffee.

People going there... could complain. Or take no sugar. Or choose a different coffee shop. Honestly, it's up to them. It's pretty reasonable to feel a bit upset though, I think, in that situation.

So, my sympathy does not extend to companies that do this.

You have costs to cover? Well, I'm sure you'll figure something out. You'll probably lose some customers and gain some others. Maybe it'll work out; maybe it won't.

There’s no reason to feel sorry for companys in this situation; it is a situation of their own engineering. If it works out, it works out. If not, they'll die. It's the way of the world.

They don't need my, or anyone else's, sympathy.
Google Fiber was stalled for years but now says it’ll expand to 5 new states
My PC sits in a place behind my table which isn't easy to reach, and I have my keyboard and mouse connected to the built-in USB switch in my monitor. Because the monitor turns off by itself to save power, there's no quick way to wake the PC from suspend mode (e.g. by pressing a key). However, I've accidentally found that turning off my desk lamp wakes the PC up! So just toggling the lamp and off will do the job. I guess it's somehow because the PC and lamp are connected to the same extension cord. The only inconvenience is that I sometimes forget to turn the lamp off before putting the PC to sleep at night.

It's pretty reliable - at least more reliable than the wireless IKEA light button in the kitchen...
You don't need a separate image. You can run a script to install a rootless systemd service that starts the Docker daemon. You just point the Docker client to that rootless daemon's socket and do things as before.

You'll need some configuration if you want to expose system ports (below 1024).

Remember to have some fun along the way (corollary: don't pick huge hobby projects that are a slog).

I'm blessed with a project that is essentially a fractal of moderately difficult and very diverse CS problems. Goes a long way to help me keep going. There is literally always something fun to do. The outcome was more of a "huh, I guess I've built an internet search engine now, neat, but about that crawler resource optimization I was thinking about..."

Donations and letters of appreciation are encouraging as well, now that it's a working product, but they didn't get me to the point it was working.
It’s easy to question the decision when you’re not responsible for making it. When you’re not responsible for your soldiers’ lives it’s easy to talk about ethics. Invading Japan would have killed tens of thousands of US soldiers, easily. When it comes right down to it, you’ll always prefer the option that’s spares more of your countrymen than the enemy (who started the war against the US.) That’s perfectly ethical as far as I’m concerned - as ethical as anything can be in war.
Burning it is better than venting it unburned, which is still subsidized in the US (though some recent, bipartisann EPA changes will hopefully reduce this).

Russia also leaks lots of it unburned too, which new satellite tech will be able to track, so hopefully there will be a global improvement on this front with well regulated oil and gas production being carbon taxed less than irresponsible production.

An easy win, once you can confront people with irrefutable evidence, but sad it takes that do something so simple.

Both China and the US officially have a "launch on warning" posture, with China only very recently switching from a "no first use" (NFU) policy which they had tried to get the US to adopt.

Formally the US calls its posture "launch on attack", which means they will launch a strike if they get a "tactical warning" of a nuclear strike.

I wonder why Jonathan Russell Clark, the author of this article, feels entitled to a platform as a yet another “cis white male”? Is it just because he uses his platform to undermine other “cis white males”?

This article pretended to a broader point, but it was really just another painful exercise in self-flaggelation from a cis white male that refuses to volunteer their own platform to a “marginalized group” while asserting that other “cis white males” ought to do the same.

As Jonathan Russell Clark himself states in his bloviatingly maximalist essay:

> “This is the bitter pill many white men find difficult to swallow. In order for space to be made for others, then space that before was given to them must be relinquished or shared.”

To which I say: you first! Recuse yourself to make room for others. Anything else is rank hypocrisy.

Or, make the simple admission that this is all horrifically invidious and nobody’s work should be judged on the basis of the color of their skin or what’s between their legs.

I'd say the decision by a state to enact sanctions is orthogonal to the size of the state.

With respect to sanctions, I think targeting financial transactions would be less appealing to policy makers if it didn't align with broader income tax enforcement goals and couldn't utilize the controls set up for that purpose.
As others have said, it depends on what you mean by hobby and the reason for it.

If it is a hobby project that you intend to make into a commercial product, stay focused, get to MVP and make sure you aren't burning effort on something that people don't want to pay for.

If it is to learn something, e.g. how to write a game, make the goals really small. Once I have learned how to move the player a bit, do I really need to perfect it?

Is it just the fun of programming? Use coding sites to compare different languages/frameworks.

You can introduce hardware to make it more fun, e.g. programming a small robot via a RaspPi or a microcontroller.

Don't beat yourself up, maybe the journey is OK but it sounds like you have a destination in-mind so focus on the outcome and chat with others to find out if there is a quicker way to at least get to the first staging post/MVP.

As others have said, if it is for no particular reason and you've stopped enjoying it, just stop it. No harm, no foul!
This thread is an energetic littering of tongue-in-cheek warnings that this game is addictive. Not sure why, but that puts a smile on my face.

Where is this happening? The US sent another $Billion three days ago: https://www.defense.gov/News/Releases/Release/Article/312005...

Western leaders have stopped visiting because they just did a few months ago, they don't need some official state visit merry-go-round to show support.

Also we do not "all know Ukraine is going to lose". In the real world, this is looking like a complete embarrassment for the Russian military. Hell we all knew the Taliban lost in Afghanistan in 2002 as well, and this is going much much better for Ukraine than it was for them.
In hot (and humid) environments I refuse wear anything except merino or linen. Both dry really quickly even in the lightest of breeze. Merino doesn't even smell if you sweat, just hang it outside overnight and it's good to go.

Everything else is just a sweat sponge. Even the fanciest plastic tech materials don't work as well as merino.
LinkedIn used to be so valuable. I owe a lot to it in terms of jobs, generating business, knowledge and networking.

Since the pandemic though it’s really become a cesspit of virtue signalling and attention seeking. It’s just people and companies shouting over each other for likes.

I like this Podman feature:

Socket activation of containers

Advantages:

- Faster network. Rootless Podman will run with native network speed. Normally rootless Podman runs with reduced network speed due to the performance penalty that comes from using slirp4netns.

- Improved security as you can disable the ability to establish outgoing connections with --network=none. The container can still communicate over the socket-activated socket with a client that has connected via the internet.

I contributed a Podman socket activation tutorial:
https://github.com/containers/podman/blob/main/docs/tutorial...

and I wrote two blogs about the security advantages

https://www.redhat.com/sysadmin/socket-activation-podman

https://www.redhat.com/sysadmin/podman-systemd-limit-access

Docker does not support socket activation of containers. (Docker only supports socket activation of the Docker daemon)

Edit: A clarification about the network speed. The improved speed is about the communication
that passes over the socket-activated socket. This communication does not pass through slirp4netns so it has the same performance characteristics as the normal network on the host.

As Jensson recommended I would learn abstract algebra first to understand concrete examples in category theory.

If abstracts algebra is too difficult then learn introduction to proofs before continuing with abstract algebra.

Try doing problems and posting them online to have them checked. Currently you can use discord, reddit, math stack exchange etc

Don’t worry about rushing it. Everything builds on itself. For instance once you rigorously study introduction to proofs you’ll see the same sort of proofs again when you begin studying abstract algebra and will already be familiar with the concepts.
Absolutely. We are big believers in best-of-breed software, where you really do ONE good job instead of trying to do everything.
Work, Work, Work – So a Few Can Be Rich
Actually I had bought a Kindle Keyboard 3G in 2011, which at the time cost $189, so not that far from the cost of a Kindle Oasis today. It served me well for many years.

While it's still working (and the keyboard is so nice to use to type in notes) the plastic case has become "sticky" and a kind of thick film comes off in places. It's strange and very unpleasant.

Recently the battery died, I refurbished it with a new battery from Aliexpress and it came back to life. When the Oasis arrived I gave the 3G to my kids.
Nothing about the current situation is permanent. They're launching more and more satellites and it's only in the eastern half of the US that subscriber rates are growing faster than available capacity.

That assumes fixed capacity, which isn't at all the case.

This is solid advice that I wish I had many years ago.

I think it's particularly important not to blind-side execs with information they can't act on or process during a meeting (related to the "don't present a problem without a solution" tidbit in the article).

Ironically, this is the stuff they _really_ need to know.

The way you get around it is by having channels of communication which are outside of the formal meeting. These channels can be almost anything but the main feature is that they're safe for both you and the exec-- you don't have to have "a solution" and the exec doesn't have to make a snap-decision.
I'm fairly skeptical of any of the social sciences per issues with the demarcation problem and reproduction of results. I'm even more so of studies with any ideological, political, or religious bend to them. That said, with the world as clearly unjust as it is at present, I do wonder who (beyond perhaps the most sheltered and naive of individuals) would still believe that the world itself is innately just? Most Western and Eastern religions teach that it is after we pass on that we are judged, not in this world. Class struggle based secular left philosophy is downright obsessed with the notion of injustice. Perhaps only secular, right, Darwinian philosophies could lead one down this road, and as a formerly right-wing atheist, I can tell you that it's not a very common world view in the least. So I'm guessing this is largely a selection bias for people who haven't thought too deeply about their views or values and are niave to how the world works.
Yeah we could give deeper into this question. Yes, the US has not adopted the technical solutions for quick (usually essentially instant) and free payments that Europe has.

And Europe isn't perfect either. E.g. in Sweden bank transfers are only quick and easy on weekdays. But then again nobody uses bank transfers because Swish is instant and 24/7, and all banks support it.

So yes, it's a technical problem that a transfer is not instant, but the "surprising delays" mentioned by previous commenters are not due to any of that.

Or do you have in mind technical solutions for improving AML/KYC handling that would reduce legit transfers getting delayed?

Sure, systems (legal and technical) can always be improved, but "surprising delay" is a problem from law, not technology. So bypassing it with technology just means (de facto) breaking the law.
