This is especially pronounced at high altitude, and when running a furnace in the winter. I keep large black tents (4x4 ft or 2x4) in every bedroom in the house, and grow kale, spinach, chard, peas, tomatoes, etc inside (with handmade COB LED lights).

I don't have any sensors to get a real idea of the difference in CO2 it makes, but it allows us to run the furnace less at night (heat from the lights), and makes a noticeable difference in humidity ( very dry air here ).

Also, we get about 1-2 family meals / week of food at full capacity ( total 4x8 grow space and 800 watts of light running only at night ).

Not economical and takes a lot of maintenance, but it's a fun hobby from which we all feel the benefits.
It works fantastically!

At first I was worried about the extra electricity usage or the extra wear and tear on the HVAC system, but after trying it at the recommendation of a neighbor, I've been nothing but happy, and I haven't noticed any change in my electricity bill so there's no worries there.

Have you ever tried to teach the right way of doing something to someone who has been doing it the wrong way for a long time and wants to argue that there's no difference?
I think the author of the piece just made a poor inference. Air cleaning isn't necessarily the same as lowering co2.

That said, seems there are some succulents that do most of their co2 intake at night. Those would work best for co2. But you would need....at least 30-40 of them.

Opening a window, by contrast, works extremely well, and quickly. However, this requires non-polluted outside air. Else you're exchanging lower co2 for pollutants.

They'd probably be the ones running the group, or a like-group. One simple tactic is to just pose as your enemy online, which is quite easy to do when it is a digitally created persona/group and not in-person.

The Russians proved how easy that is. Putin has been doing this internally for a very long time before messing with the 2016 election. Create a pro-gay group, create an anti-gay group. Foster hate between them. Others join the respective "causes" that they align with. You now know a lot of the pro/con supporters because you're running the group(s).

Here's an 11 minute clip from Adam Curtis' HyperNormalization, which illustrates this tactic: https://www.youtube.com/watch?v=kwglZTNhMNE

It's alive and well in the USA too, and things make more sense after watching it. I'd find the whole video and watch it. It's quite fascinating.
> You can't have diversity and complete inclusivity at the same time, they ultimately contradict each other.

That's because the diversity these people care about is only skin-deep.

I don't think even the AI doomsayers, deep down, actually believe what they preach. It's just a way to signal that one is clever and informed of new tech.

If they actually believed what they say, they'd be worried of being targeted by violent protestors, like drug testing companies and crop breeding companies have to be.
No, MMT is pretty much how the monetary system operates in modern fiat currency economies where the government both prints and taxes in a currency they control. The essential insight is that taxes & spending are not joined at the hip - the only real constraint on total expenditure in a fiat economy is inflation.

It’s not a particularly leftist idea - the right has tacitly treated government spending in this way for decades. It was Dick Cheney who said “deficits don’t matter” after all.

The author of this article is confused: hyperinflations are a symptom of collapsing economies, not a cause in and of themselves. Having external debts that you can’t default on in a situation where your economy is shrinking is what drives hyperinflation. Look at every major hyperinflation (Weimar Germany, Zimbabwe etc etc) and you’ll see those are the drivers of hyperinflation.

Scott Alexander (slatestarcodex) provided a meta-study and also described how reducing CO2 in his cottage reduced headaches, fatigue, and poor sleep:
https://slatestarcodex.com/2018/08/23/carbon-dioxide-an-open...

After reading this, I got a Netatmo CO2 monitor like Scott and Gwern. I found that CO2 peaked in my bedroom at around 1500 PPM at 6 AM with the door closed and that I could keep it under 500 PPM with the door open or a window open.

Scott Alexander also suggests getting around 10 succulents, if you don't want to open a door or a window.

Edit: Scott Alexander also published these survey results from other people who experimented with reducing CO2 in their homes: https://slatestarcodex.com/2018/10/04/nighttime-ventilation-...

Misconceptions, Battle Scars, and Growth
Why would someone choose a US 30 year bond as a long term investment with the government having the explicit intention to go massively over its budget?

The more a government borrows through bond issuance, the more it has to borrow later to service the debt they didn’t pay for before. Eventually this runs away to the point where there are not enough buyers for all of the debt issuance at reasonable interest rates so the borrowing costs sky rocket. This means even more debt has to be issued to service that debt... you see where this is going.

A country’s spending is capped by it’s ability to find borrowers of its bonds. Given that normal tax rates aren’t covering the spending, it’s not likely that even 100% tax rates would be enough revenue to offset these scenarios.

That’s my point exactly, people don’t see a problem as they can’t compare our current situation with what it was like in the past.

We’ve completely and utterly destroyed nature, seas are empty, air was unbreathsble at some point, all oyster banks completely gone, most wildlife going extinct and people are asking “what problem”?

Thank you for proving my point.
Pretty sure a typical human would die in the first 72 hours in cold climate.
Not to excuse them obviously but I wonder if it could have been a nervous laugh. Later in the article even the author had to cover his mouth in case he laughed during the ordeal. I know I tend to laugh myself when something really stressful happens, it's an awkward habit.

> pay us hundreds of dollars to replace the bottom half of your laptop because we made a poorly-conceived design decision

...makes it sound like it's not technically possible to replace only the keyboard. Maybe Apple is doing it for free within the warranty, but if so, if I'm reading this right, you'll have to be prepared that your laptop is going to come back with a wiped disk drive (new bottom half).

That sounds like an awful design decision. Do I have that right? (I really don't know, as I have stuck to the 2015 models, and I haven't had to open it for any reason.)
Thank you!

Lots of life is tough and complicated, and there tends to be a significant amount of shame associated with stories like mine. I do my best to flip it around and share my experiences so others don’t feel so alone if they are going through something similar. I feel no shame around my experience, and I hope others choose to not carry that emotion as well.

413ppm is now ambient. Goes up higher every year (with a small amount of seasonal variation).

By 2100, we may be at 800ppm if we continue and/or accelerate fossil burning (4 degrees C trajectory). https://www.co2.earth/2100-projections

Already a middling stuffy room, and would increase indoor levels 400ppm over today.
The fact that you can't get easily legal guardianship over an ailing parent is indicative of the problem with government intervention. Granted, you have a lot more kids who have no problem committing elder abuse. This is what happens when you chip away at the fabric of the family. Government tries to come in and fill the void and you end up with this.

Good observation. That said, co2 and o2 should move pretty much in tandem if the source of high co2 is human breathing + limited ventilation, right?

This could potentially account for why no ill effects of high co2 were found in submarines. Presumably o2 supply there is well maintained.

Do household air quality standards include o2 levels?

I am also using a 2017 model and I have to say, I love the keyboard.

It feels perfect to me as far as typing is considered. (Well, I have one issue with it, which is that I could only get an EU English layout and I used to have a US English 2015 model, I much prefer that layout, but this is hardly a butterfly-related issue!).

Honestly, I expected to hate it, especially after reading so much on the consensus about it. 3/4 of a year in, I've had little to no issues with the keyboard, mechanically. I hope that this will keep being the situation, but I can't say that I'm not afraid that it'll break. I really hope it won't, it's kind of annoying to have that sword of Damocles hanging over one's head - that much is true.

As for usability, I find the key travel distance, the firmness of the press and the clickiness to be perfect for me. It took me a while to get used to it, it felt really strange at first but then suddenly, I didn't even notice and I was typing on it like it I never had any other type of keyboard but this butterfly one. Strangely enough, though, typing on an old 2015 model feels strange, awkward, uncertain and kinda mushy to me now, even tho just using a Magic Keyboard at work still feels natural. Maybe it's just muscle memory -- as the Magic Keyboard feels like a separate device from just typing on a laptop? I don't know.

Going over to any other laptop feels so painfully awkward now, the typing experience just feels terrible in comparison to my MacBook Pro. Kind of reminds me of how the Force Touch Trackpad became one of the best pointing devices I've ever used -- any other laptop without one, even the old MacBook Air, just feels so cheap and terrible to use.

I’m running for President - Kamala Harris

I don’t read daily news or long form articles at all. At the end of the day, I don’t need to have an opinion on most things. I’d rather be ignorant than cultivate opinions based on journalists who are peddling narrative over facts.

Every now and then I’ll deep dive into an area for whatever reason. E.g. when Trump did his tax proposal, it directly affected us because of the reduction of the marriage penalty. So I looked at how it compared to tax laws in other countries. My conclusion was that the main effect of the proposal would’ve been to move is closer to the tax regimes in Germany, etc. Much of the Western world is following a trend of lowering corporate taxes, e.g. Sweden. But reporting that Trump’s tax policy follows a global trend is not consistent with how journalists today report the news (on both sides), where every story has to have identifiable villains or heros and support some broader narrative and agenda.
Hey, nice building block. I appreciate the simplicity. Thanks!
If a government merely taxes really high, either directly or through money printing, it merely does things in the positive sense. You can still improve your lot, it's just harder than it normally would be. You can even still become rich.

In a true command economy absolutely everything is determined by the government's "no", to everything. And the disappointing BIG main reason for "no" is because no bureaucrat is ever going to risk his/her position for either your fate, or your idea. Money printing does not come with any "no".

In a capitalist, even highly taxed and money printing economy, whatever you want to do, if you can do it while being sufficiently positive for the economy, you are allowed to do it (within reason).

In a true command economy, you can do nothing. You can't change jobs. You can't move. You can't start a business. You can't educate yourself. You can't help anyone with anything (even trivial things are a risk). You can't ... EVERYTHING is determined by the absolute contempt and incredible jealousy of everyone. You literally carry an old ladies' bag up a staircase ... you've just made enemies of every old lady on the block, one of which has a son who runs the town's transport department and you lose your driver's license.

There are a lot of ex-Soviets running around everywhere. Find one and talk to them.
Sure. And nature made intelligent organisms so we could take the fundamentals and build something that nature hasn't.
It's interesting to consider the parallels between this stuff and the fountain of youth, or alchemists turning lead into gold. Explorers were constantly uncovering unimaginable new things with no real idea of where it might end. Similarly alchemists who were finding that various combinations of compounds created ever more unimaginable results. So they, too, simply extrapolated outward.

I grew up with Drexler as a sort of hero. It's amazing how rapidly nanotech went from the imminent thing to change all things to, 'huh - what's that supposed to be about?' Wonder if 20 years down the line we might look at AI similarly.
There's likely to always be some minimum degree of suffering.

The NYT is called liberal, but more correctly it's pro-establishment/pro-government left-of-American-center.

They are personified by the Clinton family, yet are more pro-Bush than say pro-BernieSanders or pro-GaryJohnson.

With Trump's alternate-establishment weirdness and the extent polarization of modern US politics, the right wing is rejecting the NYT and thus pushing them farther left to maintain readership by catering to replacement readers.

To build on this discussion, what are some highlights in that book that you found useful?

I ask because I've read some systems thinking books (e.g. Systemantics) that were difficult to apply in real life. I come from the perspective of someone with a systems/theory builder personality. The only systems thinking book that I found remotely practical was The Fifth Discipline by Peter Senge.

The most useful piece of short writing on systems thinking that I've come across is "How Complex Systems Fail" [1, 2], which talks about designing systems for resiliency, and not for rigid notions of reliability.

Yes.

I’ve met people in marketing calling themselves programmers because they once wrote a PHP script.

I’ve overheard high school-aged kids at the Starbucks talking about the differences between a developer and a designer.

I’ve interviewed self-described “programmers” who struggle to write a for loop and “DBA”s who don’t know what the normal forms are.

My family, none of whom are the least bit technical, casually throw around words like “algorithm” and “server”.

The guy who works at the deli outside my apartment has asked me what my opinion on Python is.

We are definitely in a programming/CS/IT (whatever you want to call it) bubble - the level of general interest and enthusiasm for this stuff is unlike anything I’ve seen with other fields.
Penroses opinion is not exactly mainstream science in this area.
I respectfully disagree. Here's is the upper limit to when that will happen (meaning we know for sure it'll happen soon after):

- Complete behavioral reverse engineering of biological neurons, and neuronal clusters.

- Detailed connectome of the mammalian brain, e.g., first that of a mouse, then a cat, and finally that of a human.

- Replication of the above two in functioning electronic form.

Once you have this put in place, it's not hard to see that the subsequent investigation of calibration and testing of such a system, would generate new body of knowledge at an unprecedented rate. We may not immediately convert such a working system into macroscopic behavior resembling its biological counterpart, but it'll happen within a matter of years after that.

What ML/DL/RL folks are doing is only going to hasten this, by eliminating the need to carry out all of the above mentioned steps.
I think he does mean interest rates, which are not currently at the zero bound, as the fed has raised them several times lately. I think he probably should have written "trapped too close to the zero bound" which would actually make more sense. For instance the last round of interest rate increase look like they caused the markets to get very sick. That puts pressure on the Fed not to do any more raises. However if the Fed does not raise rates and if some nasty down-turn happened at this point then would the fed accomplish much by dropping rates to zero? Another idea here being that if you muck around all the time with interest rates to solve problems the effectiveness of the medicine may wear off, particularly if this medicine has delayed people from making needed structural reform. By structural reform I mean rebuilding the middle class not cutting social security or crap like that. Let me put forward a very radical idea. I suspect we need to actually restrict the amount of debt that people can accumulate as it make the system as a whole incredibly brittle. Think of consumer debt like a sort of "tragedy of the commons" situation. An individuals debt load should be their own business but if just about everyone is loading up on debt then the overall economy could explode which is everyone's business. In addition if a creditor can resell bad debt to other unsuspecting buyers then they have an incentive to give toxic loans and credit cards to people as long as they aren't holding the large amount of toxic debt on their own books for very long.

> Really? You mean you could memorize a blog post for random languages, go into an interview and answer a question and not completely fall apart from follow up question 1, 2, n?

To me, this is the crux of why I agree with you, rather than the questions themselves. Anyone can rehearse an answer to any question, but a dialogue needs to be created in order to actually find out anything about a prospective hire's competencies.

To be useful, an interview needs to be a conversation, not a monologue.
It depends on whether you can map your use case on the MediaWiki approach (namespaces, user groups). There are however Extensions to provide fine tuned access.

If you look for enterprise wikis, Twiki is another good open source software with focus on features like access control. But I don't like it for its complexity.
That was way more entertaining than I expected. Shame they don't have many views.
The "TFA Dostmann AirCO2ntrol" devices are popular in Germany. Searching for "co2 meter" on Amazon.com one of the top results is an identical looking device.

The original versioning was designed with SVG 1.1 compliance in mind. At some point the figured out they aren't ever going to support 100% of SVG, so they jumped from 0.48.x to 0.91 (it was originally intended to be 0.49), and now they are jumping from 0.92.x to 1.0 :)
The fact that you didn’t change the learning rates for different batch sizes even following a linear scaling rule let alone tuning for each batch size is pretty important. IMO without tuning the learning rates comparisons across batch sizes are pretty meaningless because it changes the effective learning rate which can make a big difference in training.
Ask HN: Remote Startup Weekend/Hackathon
I have been to many hackathons and Startup Weekends(where you create a solution for an idea in a weekend) but I know most people are not in an area that does it and for the most part, people attend these types of events to meet up. So why hold physical boundraies, open to anyone.

Are people interested in a platform where you get linked with random people and that weekend you solve a random problem/idea? You present at the end and the winner gets a prize pot? Many holes in this but feedback woul be appreciated.
