It's better to reduce emissions than to try and capture a couple of 0.0X% of CO2 in the atmosphere. That's obvious to everyone and so everyone agrees and that gets upvoted.

In reality, good luck having cows and steel (=iron+carbon) and cement on this planet without GHG emissions. Even plane fuel (long-distance flights) is basically going to have to do carbon capture to make 'electrofuels' (or biofuels) that they then burn and put back into the atmosphere, at least with how it's currently looking.

It saddens me to see that people are rambling, and others are voting it to be the current top comment, about teratons (a unit even I hadn't heard being thrown around before) which is of course a ridiculous notion. The point of this technology is to neutralize unavoidable emissions in thirty-odd years. We can't, in thirty years, start to develop this tech and hope it works the next week.

It also allows us to put a direct price point on CO2. You pick: remove CO2 or don't emit it. A smart company will choose the cheaper option. Only a few years ago, planting trees or "preventing emissions" magic accounting was considered offsetting. This sets a new standard.

So long as it's within proportion, I really see no downsides to funding the development of this tech. The roll-out to megaton or gigaton scales, yeah we should see about that when we actually have renewable energy to spare, not when the gas, nay, coal plants are still in full operation. But for now, we're struggling to reach a few dozen kilotons economically, and that's why this is necessary work and good news.
It is all fluff. SMR means many more moving parts for the same aggregate output.

No nuke can begin to approach the opex, never mind capex, of renewables + storage. So, each dollar put toward nukes produces proportionally less energy, and brings climate disaster nearer.

During the ten years from breaking ground to turning on, the money spent on coal in the meantime would pay for as much solar as needed to match the nuke's output, but the solar would begin producing and displacing carbon immediately.

Soon, even new nukes will be mothballed except where government coercion and taxes force people to pay extra for their output.

Thanks, I didn't know about fanotify. Now I'm wondering why everything I use day-to-day (file syncing tools, IDEs, etc.) still seems to be stuck with inotify if there is a better option on modern operating systems. Maybe some of them are actually using fanotify under the hood, despite components still having "inotify" in their name.
And Apple itself has a special architecture licensing relationship as one of the founding parties behind ARM Inc. Their $3MM investment ended up being a great deal for them. They can do whatever they want with the platform.
I don't think there is a precise rule. because the exact meaning depends on the context. In part 3 of the series, in the section about "branches are fictitious", that's what I will say.

The talk has an abbreviated version: https://perl.plover.com/classes/git-tips/samples/slide018.ht... It's an illustration of just one example of this: If we rebase "branch X" onto commit B, we rebase only the three green commits. But if we rebase it onto C, we consider X to contain the two dark blue commits also.

Are the dark blue commits part of branch X? It depends on what you're trying to communicate.
How would abolishing section 21 evictions sort out issues related to being priced out of the area for private tenants?

Tenants still have to leave when their 12 month fixed term tenancy ends (the most common type I've seen), if they receive an offer to start a fresh one at a raised price that's higher than they can afford.

Just to put some numbers to this for anyone unfamiliar.

Climeworks currently estimates 2.5MWhr / tonnes of carbon (1000kg) (heat energy). That's an hours worth of energy for 2500 homes, PER 1000 kg.

Mammoth sounds like it'll capture (36000 ton per year / 365 days / 24 hr) ~4 tonnes an hour = 10MWhr.

Most solar farms in the US are currently less than 5MW and thus ALL of their energy couldn't support a single one of these capture facilities.

Two Comments:

1) All that energy for 36000 tonnes / year just doesn't seem like it is viable.

2) I don't really think we should be prioritizing using clean energy to recapture carbon over replacing other sources.

Interesting question, and I could immediately propose:

-- that the subject ancestor availability on earth is considered a possibility, as they may be implicitly supposed to procreate at first biological occasion;

-- that the identity of said ancestor must crawl the female side of the chain, as "mater semper certa, pater numquam", especially supposedly in the case of the insultee.
The number of possible inputs for Income is stunning: 15 types of income in total.

There are “only” 5 possible inputs under Deductions & Credits but 3 of them are categories with several subitems:

Itemized Deductions

• Home mortgage interest

• Deductible medical expenses

• Motor Vehicle registration fees

• Charitable contributions

• Casulty or Theft losses

Other Itemized Deductions

• Other state and local taxes

• Deductible medical expenses (preference share only)

• Miscellaneous expenses

Other Adjustments

• Alimony Paid

• Keogh and IRA contributions

• Foreign Income Exclusion

• Net Operating Losses
Then what are you paid in proportion to?

As someone working in the industry, it can definitely feel like that at times. Using your analogy, ultimately a functional public pool depends on both not dumping in sewage, and also having filters for whatever gunk does get in the pool anyway. So on a long time horizon both are necessary.

seems like this would render the website pretty useless for anything before that period, right?
Weirdly, neither 'jesus' nor 'christ' appears in this list. While reddit's obviously hugely popular internationally, I'm assuming there's some North-American cultural impositions, de facto or de jure, in play. In my small circle there's a lot of compound expletives that include one or the other.

We can trace back some common expressions of surprise or frustration to this character's name / title - crikey, jeepers, gee, I'm sure there's more - but I suppose those are both sufficiently linguistically distanced to be safe, and in the context of TFA somewhat anachronistic.

I'm not sure I'm parsing this correctly: Is the implication here that TikTok is using popular music in a similar manner to a scrambler [1], allowing them to descramble and extract a "clean" version of whatever was recorded from the user's environment? If so, it's not clear to what purpose, and how that ties in to nefarious royalty games.

A counterpoint: I have an entire department of non-tech users that need to sync and version control documents at work. Not one of them has ever had a problem with SVN pulling and pushing to handle this.

I'm not used to thinking of things in the terms in which "M"ism (as you put it) casts them. He had some interesting ideas, but his idea of an ideal society (and how to get there) doesn't correspond to reality.

He was fundamentally wrong in how he views capitalist societies -- particularly his ignorance of the middle class and how access by literally anyone to equity and capital markets affects society.

Power always concentrates to a few (the Pareto principle alone assures us of this, not to mention unequal distribution of 10,000 other differentiating characteristics between individuals). The question isn't whether that happens, but how and under what terms. When a middle class of educated business owners and professionals exists, and a government that ensures peaceful rule-of-law, a society looks nothing like anything "M" describes.

He is talking about an i7 on an older node, since he is comparing the lower production cost of older nodes with their higher usage cost (electricity). I don't know what intel generation would correspond to 32nm, but that was the node discussed.
I think it improved quite a lot. I’ve just checked and it’s using 58mb on my Windows 11 workstation.

The challenge is we already have a trillion tons of excess carbon dioxide in the atmosphere. So even if you halted all emissions right now, you would still have excess carbon dioxide sitting in the atmosphere heating up the planet for the next century.
> Thankfully that's why the article first gave the metric in tons of carbon, which has no such ambiguity.

Not so quick. Does a layman have any reference point to what is considered "a lot" of carbon? Is there a way to readily measure my vehicle and see what it produces? No... and the article even attempts to provide some sort of "scale" metric, and only succeeds in making this DAC seem underwhelmingly useless, less than a drop in the bucket.

That may be so, but this still doesn't make this a good use of that surplus.
The problem is I've used multiple version control systems before git that were far simpler to use day to day, and fulfilled all of my needs. Be sad man.
Well, it's a problem for me, though definitely less than it was, so I'm personally very happy that this exists. "voting with our wallets" might make Slack put it on the prio board.

Wrong thread :-)
There are plenty of other reasons to get off fossil fuels. Burning them is bad for human health, they cause economic and geopolitical instability, supplies are finite, they cause ocean acidity that destroys ocean ecosystems, excess CO2 causes less nutritious plants, etc.

And renewables provide huge opportunities. Do you have any idea what it unlocks if you have unlimited clean energy? You could have massive, vibrant, beautiful cities and agriculture in the middle of the Sahara, and that's just the beginning.
The first three paragraphs you wrote are all very easily shown to be irrelevant. Again, the very first sentence of the post shows that the cache is designed to improve latency.

And as the article points out, the cache is in fact lower latency and does improve latency for a single request. The issue is with throttling.

The article is absolutely not suggesting disabling caching, nor does any information in the article indicate that that would be a good idea. Even with the issue pointed out by the article the cache is still lower latency for the majority of requests.

If a company is doing layoffs what do you expect them to do?

In their natural form, you are correct. But if you cut down those trees and put them in Wood Vaults, specially engineered enclosures to ensure anaerobic environments, thus preventing wood decay -- then you would properly sequester the carbon. That is literally what happened in the carboniferous period that caused all the trees to turn into coal.

There is recent research on this that indicates we could achieve a 10 gigaton annual sequestration rate with only a 5% impact on the total terrestrial tree production and at a cost of $30/ton.[1]

"The quantity of this wood utilization can be controlled carefully to maintain a desired amount of CO2 in the atmosphere to keep the Earth’s climate from diving into the next ice age, acting as a climate thermostat."

Unrelated to the site itself, which I am excited to try out, searching duckduckgo for 'brevity 500' only shows the promotion posts here on hackernews, twitter, etc. and not the site itself.

> what's more interesting and impressive to me is the overall choreography.

Yes, I agree. You've described appreciating a magical performance like a magician would appreciate the work of another magician. The general public usually focuses on what they perceive as the "trick" part of creating the illusion (such as an object hidden in the hand they are unaware of). Advanced magical skill involves understanding and then perfecting the often subtle surrounding elements that make the effect so deceptive.

In the past I've taught sleight of hand magic to relatively novice students and in the beginning they are always puzzled that even when they've learned "the move", a spectator will often just say "it's in your other hand." Yet when I perform the exact same move to similar spectators it never even occurs to anyone that something might be in the other hand. The difference is a dozen subtle things from where my eyes are looking, to the position of my body, to the pacing of my speech. I had to learn these techniques from my mentors and then rigorously practice them until perfected. In a lot of sleight of hand magic, any "move" by itself is not all that deceptive. The context and choreography around the move are what elevate the performance to what seems like real magic.

> Did social media absorb these forums? Did messenger apps absorb them? Did Discord absorb them? Did Reddit absorb them?

Yes to all four.

The classic forum experience (I'm talking phpBB2 and similar) is incompatible with the dynamic UI/UX the modern web audience expects. The lack of comments being formatted as a tree is likely a deal breaker on its own.

I mean, a $15/tonne carbon(dioxide) tax would raise the cost of a 20lb bag of charcoal by $0.50, or about 3% based on a quick search. So the BBQing itself is probably not prohibitively expensive.

I use it, maybe once a year since 2008 or so, in order to create illustrations for technical documentations, however I found myself playing with it.

It is way more than a set of pencils and brushes, as it eases up many fundamental actions (managing which object is over/under another, scaling/rotating something up/down, aligning...) in an (IMHO) intuitive way.

Suggestion: install it and progressively explore embedded tutorials ( https://inkscape.org/learn/ ).
I don't buy into this theory. We have plenty of minds currently and are failing to avoid and solve planetary scale issues. My take is that this is an incentive problem, not a lack of cognitive capacity.
The reason I linked the NCA above is to clarify that we have data on the severity of this problem.

Everything you said above about Science versus Policy is true, as a generic matter.

Problem is (as you can see in the GP comment that sparked my own comment) that a lot of HN commenters seem to view the Science piece fundamentally un-settled.

And another problem with your statements above is, as I was gently pointing out, that very well-informed and deliberative scientists -- I'm talking about people who have done geophysics their whole life, and are not temperamentally given to alarm -- have become very alarmed indeed about the our lack of responsive Policy around this.

So generic comments like yours (that could apply to any interface of Science and Policy, including cigarette smoking or leaded gasoline) that don't address the specifics of this particular problem come off as, well, pretty low-information.

And this is not "rational skepticism", just a boring kind of generic contrarian stubbornness.
It's probably against their terms of service, so maybe. It probably depends on a combination of (over)zealous automation and whether they feel it's in their expedient interest to crack down on.

The first thing I looked for was a comparison with the official Slack client in terms of performance, since that's the only reason why I'd consider using this. Numbers for CPU load, memory use, time to perform certain actions, crashes. Doesn't seem to be anything available on the site regarding this, which is a shame.
I like the idea of using novel biological methods to capture carbon. Maybe we will end doing something like that, and I know you're just spitballing here, but the economics of scaling microbiology tools is very wasteful in terms of environment.

The inputs for petri plate growth have a demanding level of refinement. Pure sugar, yeast extracts, salts, gelling agent, all dissolved in D.I. H2O. Sterility requires autoclaves which are energetic monstrosities. Without these conditions the culture will become contaminated and overgrown with stuff you don't want.

Innovation could solves these problems, but it's going to be hard.
It’s not a bad solution, as long as the robot is remotely controlled by a human and has no autonomous capability. It can just sit in a closet unless it’s required.

He was writing at a time very early in the development of democracies, and democratic institutions. If you have a free society and democracy, then there is no place for violence.

Violence imposes an inequality in power in favour of those who are more violently inclined over those who are not. It further empowers the strong and further disenfranchises the weak or disadvantaged. Heinlein called voting the exercise of force, but that’s wrong, it is the ultimate exercise of speech. It’s having a say. The process of voting is one of giving all a voice. Violence is inherently anti freedom, anti speech, it is an attempt to silence or coerce others through intimidation or death. They are opposites. He called an armed society a polite society. Democratic societies shouldn’t have to be polite, they should be free to be impolite. Free speech means freedom to say things others don’t want to hear, otherwise it’s no freedom at all. Vetoing that with a threat of violence is tyranny.

So no, I’m sorry, I know Jefferson and the founding fathers of the war of independence are heroes in the US, but in the context of a democratic state he’s just flat out wrong.

If you have no voice, have no vote, or if the system is corrupt or unfair then sure. In that situation you don’t have a say, so violence might be justified. They were justified in taking up arms against Britain. But if you do have a say and resort to violence to impose your views anyway, that’s oppression.
