Something I really like about lithium is how recyclable it is. I read some time ago that lithium batteries do not "die" the same was as other batteries. The shortening of lifespan for these batteries is not about the lithium wearing out, but rather the oxidation of the leads and terminals inside the battery. Thus lithium can be recycled for a long, long time.

Any chem engineers out there able to confirm?
We have to be very careful. The elites will not give up power without a fight. We will either get root and branch reform of the federal government, or a police state.

> Finally I find it a bit odd that someone so concerned with privacy uses so many Google Apps. Isn't that rather counter productive?

There's another angle to it that I think is more important to many - not having access to Google apps you're used to is fucking annoying, to say the least. Bing is nowhere near good enough or convenient enough to replace Google for search and translations (and DDG is blocked). If, like me, you use GMail and Facebook as primary means of communications, then GFW basically cuts you out from family and friends.

> Also, only web based gmail is blocked. Access from Mail.app or iPhone's Mail is not blocked. Sadly translate has been blocked for about a year now... all the more reason to never turn the VPN on your computer or phone off.

GMail for Android (and Inbox by Google) are somewhat blocked. So is the Facebook app and Facebook Messenger app. I had periods late at night when my phone would suddenly download a few e-mails or receive FB notifications, but the "connection" lasted something like 30 seconds.

RE censorship, GFW is already effective enough, even if it's a side effect. See:

Thanks for linking to the old NYT article on Frank Rosenblatt's work. One can see how researchers of the time were irked by delirious press releases when the credit-assignment problem for multilayer nets had not been addressed.

(We managed to mostly address the credit-assignment problem for multilayer nets...but the delirious press release problem remains unsolved.)

"But economic inequality isn’t the symptom; it’s the virus that attacks. You, Graham, like the rest of America, have been deceived. You are a victim of the American Dream, the belief that anyone who works hard can move up economically regardless of his or her social circumstances. American cultural optimism is one of the greatest lies ever told."

A while back there was a company called Toxco which I think got out of the business of lithium recycling. Look up the company Retriev Technologies. They recycle lithium batteries. It's absolutely recyclable.

> Startup as PG defines it in his essays is a company that's experiencing rapid growth - often to support growing rapidly you need a lot of money.

I see this response a lot, but that just begs the original question. Why is a startup with VC money a good model for a business? Why not a bootstrapped, "lifestyle" company? What empirical data do we have that effective long-term wins for investors and employees and the world (and not for VCs, who are simply artifacts of the startup ecosystem) are more effectively or efficiently accomplished by startups and not by slow-growth business—or by nonprofits, or bored hobbyists working on things "just for fun", or anonymous pseudonyms who post research papers and then disappear, or anything else?

Facebook was a slow growth case in the early days: you had to be a member of certain colleges, and eventually all colleges, and only later the general public. Unlike Airbnb or Uber or another business with a good reason to start in new cities slowly, Facebook's closed registration prevented them from getting any of their users' complete social network for little obvious benefit. There were a good handful of systems at the time with open registration and a similar target user base that are nowhere near as successful (like MySpace, LiveJournal, Xanga, etc.). It might even be possible to make the argument that Facebook's slow growth was important to getting the product right, but in any case, it was certainly the nature of the product more than the ability to grow that helped it.

This is interesting in how un-interesting it is.

Find product-market fit before taking investment. Because the only reason to take VC investment (for the etype of startups we are talking about) is as a steroid injection towards growth.

Why is this the only time it makes sense? Because that's the only way you and your investor's incentives are aligned.

Now, whether you need to/should grow fast to survive in the long term is another question.
Yes, finding something that teaches you how to do something you want to do is useless. Unless it's something YOU want to do, of course! Then it's fantastic.

So as I was writing a reply, I found that my opinion doesn't actually differ in "do we need to do a bunch of stuff"; it's more that I don't think miri is taking a useful approach. After talking to a friend who is also in ml about this really, I think the key point I should make is that it's more a matter of engineering control tools that ensure we can spy on its thoughts. If we can build an agi, we can also build safeguards that it doesn't realize are there until too late.

Anyway, here is the original comment I was going to write. You can read it and extract your thoughts; I'm fairly confident I got the theory right, but I've reduced my confidence in the point/counterpoint. Regardless, I definitely think miri's position is unreasonably extreme, and this is a pretty ok explanation of why.

The problem is one of scale. Bitcoin is heavy resource-intensive. So much so, that your Core i7 can't really do anything. These days, not even the latest GPUs can compete. You really need specialized hardware, and a ton of it. And so, money.

If you customers 'get bored' with your product or service, it won't matter whether you go fast or slow: you aren't chasing a real opportunity.
Good point, GOG is another modest success story for DRM-free content. That said, success is a relative scale here: even a hit like Witcher 3, where there is an obvious commercial association between GOG and the developers, only sold slightly more copies on GOG than on Steam, while most big name titles either aren't released on GOG at all or sell many times more through other channels like Steam. If we saw the likes of EA and Ubisoft backing off DRM for their new AAA titles instead of doubling down on it even in the face of some very obvious problems, it would mean a lot more in terms of industry direction.

Chimpanzees Trust Their Friends [pdf]
Can't speak for the original poster, but my issues with services like this isn't that it's delivering fancy coffee to lazy people, but the economics surrounding it.

There are three broad categories for these types of services:

- High pricing targeted at wealthy people, paying sustainable wages to the laborers who provide the actual service.

- Low-mid pricing targeted at the mass market, paying sustainable wages to the laborers who provide the actual service. These companies end up dead.

- Low-mid pricing targeted at the mass market, paying unsustainably low wages (a small fraction of minimum wage) to the laborers who provide the actual service.

My problem is with companies in the third category, and there are many of them. Silicon Valley may not have invented the hollowing of the American middle class, but it seems to really enjoy building businesses that rely on an endless supply of desperate laborers to exist. Businesses in the third category simply cannot exist without extreme inequality, extreme desperation in the lower classes, and a seemingly inexhaustible low-skilled labor pool, and in this way they are IMO representative of the worst tendencies of American culture/society.
Ask HN: How to protect my 401k during stock market turmoil?
I started putting money 401k at age of 29. I know it is very late but better than never.

So far I have lost $1000 due to fact that stock market being 7 % down for last few months. I have moved money to get more funds related to bonds but not sure if that is going to protect my investment ?

I have $20k hard earned money in 401k which has returned $250 as dividends and lost $1000 due to market.

How do I protect my 401k ?

I am not American Citizen but why do US put retirement investment such as 401k in stock market ?

It's not very unlikely; it's something that will definitely happen at some point (in the case of SourceForge, well over a decade). Most projects will migrate away, but there will be losses.
I think when I tried to use it, it enlarged all my stack allocations. When using precise stack allocations (user threads), it causes all the stacks to blow up.

I've wondered what about Digital Ocean users love so much (I'm a customer)? They are not the first to offer cloud housting at cheap prices (I've used slicehost, EY before they became pricey in the past).

It seems strange to consider a currency as a viable alternative for other currencies, when a sizeable chunk of the total available sum of it is owned by a single person or group simply because they came up with the system, and another large part is in the hands of speculators. There is nothing fair about a currency that is so volatile in value by design and is essentially speculative in nature.

It is sad to see that this side of Bitcoin is not stressed more often.
You can not venmo money instantly. The UI makes it seem that way, but it takes a few days for payment to process and as such, Venmo has become a target for scams:
http://time.com/money/4036511/venmo-more-check-than-cash/

So do not use Venmo for commercial transactions (buying things of Craiglist for example) and do not assume the money transfers immediately.

Also shame on Venmo for misleading their users; they should do a better job of explaining how the transfer actually works.
I don't think it will ever happen. They are too scared of the labels.
I think if they communicated that consistently and clearly, people would be disappointed, but they would understand. After all, Github's users are developers who probably struggle with these same product trade-offs. The biggest problem is the lack of transparency or feedback in the product process.

Looks like a null result that has been p-value hacked. Without the (paywalled) original paper it's tougher to say, but:

The effect only occurs in teachers with less than 10 years experience, and only teachers in Switzerland and Austria, not in Germany. Population of Germany: 80 million. Population of Austria: 8 million. German speaking population of Switzerland: 5 million. Approximate average career length for a Physics teacher in German speaking countries: 30 years.

So about 4.5% of their sample exhibited a bias against girls. The typical p-value to accept a result is .05. If we sliced and diced the sample into 20 groups, we would expect one to show a significant effect at p<.05, which is exactly what they showed. Note that they did a retrospective analysis based on years of teaching experience, gender of teacher, country of teacher, and fake major of student. There are plenty of combinations of subgroups to find something that makes it over the p<.05 hurdle.

Can't find a non paywalled full text of the original paper, but it looks strongly like p-value hacking a null result to me. They found no effect in 80 million population Germany, and only an effect among teachers with less than 10 years of experience in 8 million population Austria and 5 million population German-speaking Switzerland. If we assume that their sample is evenly distributed across German speaking Europe (The test question was in German),
I'd say they're different, but definitely not orthogonal. NPS asks if you'd recommend the product, retention is how long you stick around after first use. Both metrics embed the user's affinity for the product (which is the underlying thing sama's saying to measure and improve).
If you are a VC backed startup, growth solves all of your problems (at this particular point in history). If you are a non-VC backed startup, sales/profit solve all of your problems.

Either way, growth is a wonderful thing and I think you should grow as fast as you can.
All true equivalency statements are tautologies -- since both sides "resolve" to the same thing. That doesn't mean they are useless.

In this case, though, it's not "Everyone who has died has died", but "To have lived means you're dead".

The same way that "to be a corpse means that you've died". That's not a tautology (it's not "to be a corpse means you're a corpse"), just informs us of a prerequisite for the other thing to happen.

Millennial here, it's a lot more cost-efficient to brew and enjoy my own coffee. Coffee snobbery is rampant these days.

It's an excuse to call others 'casuals' and 'plebs' while at the same time it's a masturbatory jerkfest to show off their brand new iCoffee. It's all I see out of my generation. People one-upping others to make themselves feel good.

It's pointless. You can call these people 'yuppies' or 'hipsters' but to me they're all the same regurgitated ignorant loaded trash in the end.

There's people who realize this and next thing you know you have outrageous business ventures like this. I can't see this lasting long at all.

Coffee shops? Sure, OK, it's a social event. Coffee delivery? Ignorance may be bliss but it sure is expensive.
This reminds me of pg's comments about "playing house". The appearance of a startup is more important than the reality of a startup, for founders whose core drive is to "be a startup founder", not "create this product the world desperately needs so maybe it will stop haunting my dreams".

I've met founders like this, recently. They're building some sort of social app that does something no one needs and no one would pay for. Maybe I'm being dense and they're actually geniuses, but I don't think so. Most startups fail, and I think a lot of that is because a lot of startups are really stupid. They're "solving" worthless non-problems because the founders aren't doing the hard work of finding real, valuable problems to solve.

Building a great product is really hard. And it can't all be done completely lean - at some point, you need to envision something so profound that people don't realize how much they need it. You don't just write Hello World, charge a buck, growth hack, and brag about how you got two bucks for it the next week. As Henry Ford said, if he'd asked customers what they wanted, they'd have said faster horses. Don't build a faster horse. You won't be great that way.

Right! I'm not interested in breaking the Internet Archive, and I'd expect it to move to IPFS [1] eventually (content addressable web) [2]. If/when/how that happens, I'd expect traditional http tooling to still work (curl, wget, etc), which is why I went looking for a status code that indicates an alternate path for the resource/content.

That's why my above comment kept getting edited as I did some more research. 503 is an ugly failure. 429 tells the client to back off, but it doesn't provide a fallback to still get the content. 303 does.

I thought this train of thought was in line with Brewster's blog post [2]. Apologies for the confusion!
