Wouldn't there be an additional stepping at the transformer for level 1 and 2 chargers to go from AC distribution grid at 480V AC to 110V/220V where the level 3 superchargers can plug directly into the 480V AC mains without a transformer?

> Incorporating stationary storage cuts down on the costs incurred by both of these inefficiencies.

at the cost of 10% more power usage due to the inefficiencies of charging and discharging batteries. Might still be worth it from an electric company's bottom line, but in most markets, it increases greenhouse gas production because we need more kwh of power.

Seems like the only reason Salt Iodization doesn't make the list of "top" charities is because it is much harder to prove benefits back to the charity level. If a charity lobbies the local supermarket to label iodized salt which people want which causes better health, it is nearly impossible to prove that it was the charity that caused the better health. Malaria nets are much easier: How many nets went out, did the nets make it to the people we intended, how many fewer people got malaria? Iodization is much more difficult to track because so much money needs to be spent at the lobbying level instead of the "buying iodine" level.

Malaria nets also score extremely well in their ranking system because those charities can accept a TON of money before diminishing returns start to kick in. Against Malaria has said "we could easily accept >$50 million in donations" where the two Iodization organizations GiveWell tracks have said they could probably only accept $2-5 million without major changes (even though both of them lost their primary funding sources in the past few years and are thus decreasing their programming).

This all doesn't mean GiveWell is wrong in their current recommendations. They are up front about disclosing the problems with their methodology, but you should keep it in mind when choosing which charities to donate to.

Sounds like you've been bubbled by search engines and social media. I'm in Denver but my wife is from Nashville. Nashville has bulgogi[0], has 3 different companies competing on the health care exchange this year[1] and Vanderbilt is an amazing medical college, and the city has 3 different ISP's offering gigabit internet[2]. There is a ton of greenspace with bike trails through the city. The sports teams have been doing pretty well the past few years. There are tons of "lakes" nearby for enjoying during the summer, there is some amazing hiking nearby, especially near Knoxville (including the Appalachian trail). Homes definitely aren't as cheap as they used to be there but still doesn't even compete with Denver, which doesn't compete with Seattle, which doesn't compete with SF. And that is all before I even got to the music scene which is by far the best in the country for more than just country music. Pop, country, jazz, rock, all have a home in Nashville. Karaoke in Nashville is an incredibly fun and incredibly intimidating proposition.

I've heard the Thursday evening flights into Nashville called Bachelorette Flights because so many bachelorette parties go to Nashville because it is a really fun city to go out on the town at night.

All of that and they still have no income tax.

The AWS bill for my first personal website. Being able to say "I built a website on AWS" in 2009 was probably the reason I got my first job making >100k.

Patio11 talks about charging more a lot: http://www.kalzumeus.com/2012/09/21/ramit-sethi-and-patrick-... http://www.kalzumeus.com/2015/05/01/talking-about-money/ https://training.kalzumeus.com/newsletters/archive/consultin...

His argument basically is that, businesses/consultants/employees fail because they charge/bill/demand in salary negotiations too little WAY more often than they fail for charging too much. Therefore, you should charge more than all of the decision making biases in your head say you should charge.

I feel like the author missed the biggest problem. There is a huge dis-incentive to use bitcoin as a medium of exchange because it is inherently _deflationary_. If I know bitcoins will continue to increase in value because math, why on earth would I ever exchange them for something that doesn't?

I agree. "Manual" is a little generous. Especially for solar there are some much better resources if you step up to the RV world: https://therecklesschoice.com/2016/04/29/diy-rv-solar/ or https://handybobsolar.wordpress.com/

The smallest nuclear plant in the US generates 582 MW of power with a capacity factor of 92.1%. That capacity factor means that in a year you'll get 582MW * 9258 hours per year * 92.1% = 4.9Trillion kwh/year of power. That's how much we need to replace if we chose to shut down the SMALLEST nuclear plant in the US (the largest is almost 4,000 MW).

The largest wind turbine being designed anywhere in the world right now would be 500 meters tall (taller than the empire state building) with 200 meter blades and at peak output would generate 50MW. Capacity factors for on-shore plants in the US average about 33%. So 50MW * 9258 hours per year * 33% = 0.152T KWh/year. The largest turbine currently built in the world gets 8MW not 50MW so 0.024T kwh/year.

I.e. we would need ~200 of the biggest wind turbines ever built to equal the amount of energy we get out of the smallest nuclear reactor currently running. And that is just to break even. Comparing the median nuclear plant to the median wind turbine makes the numbers even worse.

Hydro has the problem in the US that there aren't any good sites left. Solar costs even more per KW or per KWh than wind does (~1.5x is what I've seen at grid scale in the US) especially when you include the storage needed to maintain consistent supply throughout a day (~3x wind)

Not true. Hydro is a great example. The majority of hydro deaths are caused by dam failures. The most deadly dam failure in the world was the Banqiao Dam. It's failure caused 85,000 direct deaths and an estimated 150,000 deaths due to famine caused by destruction of cropland. Even in the US, https://en.wikipedia.org/wiki/Dam_failure lists 498 deaths in the US alone since 1945 while generating significantly less power than nuclear has in that time. And that doesn't include the tens of people who die in boating accidents related to dams every single year.

I agree with rcoveson. I see your stats and say "world-wide we ONLY have an accident every 19 years? Wow that's amazing, we can produce all of our energy without carbon and only deal with one accident in the world every 19 years! Hell yeah, we solved this energy problem!" (Yes I'll agree the rate would go up as we add plants but still, that is an incredibly encouraging stat, not a depressing one)

This seems amazing but you need to have your order form automatically redirect to https. This is a really big deal. I almost didn't purchase because of this just so you know. Sure I can type the extra 's' in myself but 99% of your customers aren't going to do that. Even if you aren't worried about the security issues because you use stripe, your customers are going to get "don't enter credit card info on sites like this" alerts from most browsers (chrome told me not to buy). Please enable a redirect now.

Totally agree. I work from home and walk or bike most of the time. Most of my car's miles are put on doing >200 mile trips. Plug-in hybrids for me until the charging infrastructure vastly expands.

You're not calculating it right. 40,000 - 6300 for the standard deduction - 4050 for an exemption = ~29,000. First ~9000 is taxed at 10%, next ~20,000 for this person is taxed at 15%. Total income tax that could be reduced by the $7500 rebate for this person would be ~$4000 worst case.

We do this and thank God we do. Our marketing emails get down blocked all the time simply because of the scale (and our marketing team is a little over zealous) but after our transactional emails got blocked for the 3rd time we moved all marketing to another domain and gave been happy since.

Perfect thank you.

>That's the most common way to consume cannabis.

I'm very suspicious of this claim for users in Colorado without a source. Anecdotally, the vast majority of legal use I see in Colorado is edibles. They don't have the stigma of smoking or the (legitimate) smoke inhalation concerns and thus seem much more popular among legal users.

Wow, thanks for that info! Our enterprise account uses CF as a CDN for medium sized (~50MB) video files and I just assumed that they were ok with everyone doing that. I guess not.

I guess the answer for the OP then is, get an enterprise account and you can do whatever you want.

NASA does things this way but SpaceX explicitly does not. Rather than using 1 space hardened part, SpaceX usually uses 3 non-space hardened parts (processor, memory, bus, etc) that all do exactly the same calculations simultaneously and then compare every single answer and ignore it when one out of 3 parts disagree. This allows them to be both cheaper and much less power hungry because they operate at least 2 process nodes smaller than NASA hardware. I've seen data that says that while each individual processor will experience space related errors quite often, the whole 3 part voting system is at least as accurate as the way NASA does it.

This was us! Added CloudFlare in front of every bucket with our own "cdn.example.com" DNS name and changed every reference to s3 in code. Didn't even know S3 had problems today until I saw this on HN. (note: This outage taught us to set up monitoring of the S3 assets separate from the "cdn")

I'm bothered by the move to TouchID and now FaceID from a "the government can make you unlock your phone" standpoint. Legally, the precedent is that the government can force you to use "something you are" like your face or fingerprint to unlock your phone. Currently there is at least some ambiguity to the precedents that say they can't require you to unlock your phone with "something you know" like a pin or password because of that could be construed as self-incrimination and forbidden by the bill of rights.

If you're worried about law enforcement requiring you to unlock your phone DO NOT USE TOUCHID OR FACEID.

I'll be honest I'm glossing over some details about house refinancing and sales etc. About 40k of it was gains from a house. I'll give you that. About 75k of the 300k is investment gains. Income has remained pretty stable over that time (when I got a raise, my wife worked less or went back to school etc) and we started at that income level right out of college at 22 years old. So of the 500k, 115k is gains, so $375k is contributions/debt payment. In the 8 years since graduating that would be ~$45k/year. $125k-45k= $80k in taxes and spending per year for two people which isn't hard at all. Lived in DC for a year then moved to Denver.

At this point, of the 300k, about 225k is from contributions (savings) and 75k is from gains. The bigger the account gets though, the bigger a percentage the gains will be as the account grows faster than my annual income does.

Vanguard mutual funds. About an 80/20 split between VTSAX (Stocks) and VBTLX (Bonds). Nice and simple. I re-balance with monthly contributions.

Yes I am, just used those as the metric for meeting the $500/month landmark from the title.

How did the rights for that work out? If I were an employee when I built a tool to solve a problem like that I would expect the employer to own it. Can you talk to how that conversation went?

30, ~125k household income for two adults no kids, IT and teacher. Our income made it a little easier to get here but the $200k hole of combined student loans we started with (now fully paid off) probably counters that pretty evenly.

I've cut my expenses and invested the extra in index funds. Currently at a nest egg of around $300k which spews off dividends of around $500/month and is currently appreciating a bit faster than that.
