I mean... 1 million requests an hour isn't that many.

That's around 300 requests per second. Assuming 1000ms upper bound on requests, you need 300 workers to handle that load. Assuming 150MB per worker, that's 45 GB of memory required to handle the load. So like... 5 m4.xlarge instances on EC2 (to give redundancy and allow loss of 2 hosts). That's $700/month.

That's not that much. We've got a Rails app that pushes 5000 qps. And to be fair, we just dial up the number of instances and it handles it fine. It runs on over 100 instances. It costs us around $10k/month. Not the end of the world, cost wise, but we have multiple Go services that handle similar levels of traffic and run on a dozen instances. Additionally, deploys take a long time (rolling restarts plus health checks on 100 machines takes time).

Moving to Go (or Elixir) allows us to handle far more requests per unit of hardware. While latency would indeed improve, it's not the primary motivator for us moving away from Rails.

I haven't even mentioned the websocket story on Rails. That's a whole new can of worms.
It’s very similar to the question of whether it’s better for the government to provide healthcare or to get it from a private for-profit megacorp with an army of lobbyists. The government is by no means perfect, but at least their incentives are aligned with mine unlike a corporation with obligations to their shareholders.

The FCC was doing fine until Trump in my opinion. The telecom/cable/ISPs have been problematic for a long time due to natural monopolies and too little regulation (in my opinion) but the FCC’s actions have usually been attempts to fix those problems (when the industry lobbyists don’t win out)

If we are going to throw the FCC under the bus because it has taken a huge turn for the worse under Trump, then we’ll also end up saying the same thing about nearly every government department. DeVos is making a joke of our education department, science and environmental positions are filled with people who don’t believe in them, the State department has been shedding experienced diplomats as quickly as possible, etc.

It’s easy to blame government for these things (and more checks and balances, particularly on executive power, would certainly be welcome) but unregulated private schools and letting companies be stewards of the environment is much worse.

Good point, although one advantage with Rust is that it plays well with C -- so you could keep some C drivers or libraries, and do the rest of the work in Rust. That reduces attack surface area while providing a smoother on-ramp to full device support.
My bottleneck with Rails was always memory usage. Our concurrency was always limited by how many web and task workers we could run in the amount of memory we could afford, which was not very many. It was not straightforward to optimize this and ignoring it didn't work for us, so we put lots of time into it and it changed the whole productivity argument for Rails.
We are lucky to have lots of family on the farm here with us, so it was actually a bit of an upgrade in terms of family connections. It's multi-generational. Leaving friends behind was the biggest adjustment. That and Toronto food/music are the biggest adjustments for us.

> This just simply isn't true. Losing the money means they spent it and got nothing for it. But every penny they spend, they get a lot of things - battery technology, market share, mindshare, network effect lockins (superchargers), etc. Tesla isn't losing its money, its investing it.

Yes, and such things are reflected in their balance sheet under "Assets" and "Goodwill". The problem with Tesla is that after accounting for their "Assets" and "Goodwill", they're still negative.

Tesla says its "Goodwill" is worth $461,989,000 in 2016 for example. See its 2017 10k if you don't believe me (its in "thousands", so search for 461,989). http://ir.tesla.com/secfiling.cfm?filingID=1564590-17-3118&C...

The rest of Tesla's assets, which include every factory, every bit of cash, every investment... was estimated to be $ 692,925,000.

That is, Tesla believes itself to be a $1 Billion company, but roughly half of its valuation is "Goodwill" and brand recognition.

Believe it or not, Wall Street has names for the things you've described. Its all part of the calculation.

----------

Anyway, after accounting for all of that, Tesla is still losing money, quarter after quarter, year after year.

The point is that it's so easy to fall into the trap of comparing yourself to the artificial lives of professional "influencers" on Instagram who are selling you a lifestyle for their own gain. It isn't so much "ignorance is bliss" so much as realizing the life they sell isn't really real. Even among "non-influencers" everyone is optimizing posts to show the happiest parts of their lives, which is a tiny slice of our reality.

When you're feeling depressed or anxious, being bombarded with a feed of artificially happy people only makes you more depressed or anxious.
>> the kind of free speech enshrined in the U.S. Constitution

> The Constitutional guarantee of free speech mandates the behavior of the government to not interfere with the rights of private actors

Free speech is an ethical concept that is (imo) fundamental to open societies. The US Constitution enshrines this ethical ideal by creating a prohibition against government interference in free speech. GP is lamenting that major corporations do not seem interested in the ethical ideal, not claiming that the codification of the ethical ideal found in the US Constitution requires major corporations to permit certain types of speech on their platform.
Again, not speaking from experience here, but it should be easy enough using tools like https://docs.rs/bindgen/0.31.3/bindgen/ to generate FFI interfaces to C libs where that is needed.

So, I wouldn't necessarily say that's a blocker. Obviously everyone should make the best choice given their business requirements, etc.

The article is a call to action for Facebook to work with local stakeholders in order to differentiate and treat differently local propaganda from genuine news. The author doesn't believe that Facebook commits enough resources to that effort and cites an email from Facebook that says there isn't a one-size fits all solution, which it seems, to the author, what Facebook is trying to do. The author is also saying that Facebook has a moral imperative because its lack of being involved is causing great harm to people and uses the "Rohingya" as an example. If you country is controlled by a Military Controlled "Junta, than the real name policy has a staggering different effect in Myanmar than if it is in the United States where there is a strong rule of law, for example.
It sounds to me like the ground level is exposed outside the device in this case.

It's worth noting that there is a risk here. LSD can put you in a mental state prime for significant changes to your psyche - in either direction. It's vitally important that the right scenario be crafted or the trip could spiral into a tramautic experience, especially if they have a terminal illness to dwell on during the trip. LSD is an amazing drug with potential to help people, but let's not forget that it can be dangerous and administer it carefully.
Sure, either way sounds plausible - the point is that this study doesn't tell us how much of an effect runs each way.

That is sort of the point. Once all speech transits corporate networks and those corporations are empowered to censor that speech then the public square protected by the U.S. Constitution no longer exists.
EV tax cuts are not gone. Some versions of the tax bill proposed to remove the federal tax credits. Also Tesla will reach the 200,000 threshold of cars sold where the credit starts to phase out. But there are still state incentives.
Diet for a Small Planet also found that at the time the book was written, there were no countries incapable of feeding their people. Starvation mostly had roots in political problems, including civil war. It wasn't due to an absolute lack if food.

Sending food to starving countries often isn't a panacea. Frequently, the same political problems that caused the starvation in the first place prevent the food from getting distributed to the people who most need it. If it does get distributed, it can change the tastes of locals, who will now want to purchase a Western diet that they can't really afford. This leads to more hunger as people reject a diet of affordable local traditional foods and spend money on meat and wheat and other products beyond their means.

The first half of the book is a political piece. The second half is a vegetarian cookbook. It is one of the best books I have read.

Well, it's not exactly a startup anymore either, which is what it sounds like you're describing (escape velocity). They're a public company that has existed for some time. But like you say, really, it's valued on "faith."
Thanks for crunching the numbers!

Yes. I run the behavior-change company Pavlok[1] -- our goal is quite massive -- to help 100% of people achieve 100% of commitments they set. That means, ending addiction, 100% adherence to diets, etc.

We create technology (the Pavlok wearable, and the Shock Clock at this moment), offer coaching, create courses, and much more to build the world's first truly effective behavior change platfom.

I wrote a FB thread about our mission and how we broke it down recently.
"For the rest of my life, I'm committed to one mission.

Upgrade Humanity

It becomes one goal, broken into two parts, and 3 stages.

One goal: invent the vaccine that cures humans from not doing what they say they will do. Absolute (100%) success --- or I have failed absolutely. (same success rate as the smallpox vaccine)

Broken into two parts:

1) End addiction

2) change the meaning of money from "money is what other people pay me to do what they want me to do" to "money is where i get paid when I do the things I want myself to do"

And the 3 stages are encapsulated into our mission statement: "Upgrade Humanity."

1) Break bad habits that hold us back

2) Form good habits that help us become who we could be

3) Create new sensory inputs (sixth sense technology) to augment and increase human capabilities

Anything that isn't in line with that mission needs to move the fuck out of my way.

How many Model 3 cars were supposed to be delivered by now? 5000 per month? Or something?

The company, instead of working out its issues with the Model 3, hype up the Tesla Semi and Tesla Roadster, in hopes that people forget about its Model 3 issues. This is a company that's tilting way more in the "hopes and dreams" category than any actual, physical deliveries.

We should not forget, that bad press about tesla is in the interest of Jim Chanos, who is a billionaire and has a big short against tesla. If Tesla stock falls, he wins. Since he holds this short position, he is in the press once a month.
Right now, their pp&e and working capital seem like they could be liquidated to pay back debt, so agree that bankruptcy doesn't seem to be a near term concern.

However I don't know what covenants are in those loan documents, and its possible that given the delays tesla could trip a covenant and get in trouble with lenders. Though I'm sure Elon has worked his magic on them as well

Hard to say if they're doing fine at this point, as the model 3 doesn't really show up in the financials yet. The real concern is that model 3 production capacity increases without sufficiently decreasing production efficiency. So revenue goes up but COGS skyrockets, and the business is structurally not profitable on even a gross profit basis. This would lead to huge financing needs, and also probably a drop in the stock price (though the stock price seems immune to dropping). This could lead to company failure and is not a theoretical risk

bluetooth will generally "just work" when using two devices with the same manufacturer's chipset (this is not a rule by any measure though).

in my experience, many bluetooth hiccups are caused by manufacturers having alternate readings of the bluetooth spec, which is a massive, hard to swallow behemoth.

if you have two 1st party BTLE devices, you can expect to see bluetooth at its best. for example, apple airpods + iphone are probably as good as youll ever see a bluetooth pairing.
Boy, I sure am glad alcohol is illegal.
The point is exactly that people do not want something like a man page, so they make their own thing that's not like a man page, and the suggestion "go contribute to manpages instead" isn't a good one, because it would mean making bad man pages (or not fixing the issue people have). If aspects are useful for the man pages (e.g. to make better examples sections), they can still be pulled out and added there as well.

>> development process company focused on learning and iterating with the production being only by-product

That's not a company you're describing, that's a research lab. Either they win big by discovering some revolutionary tech that they can patent and sublicense to the established car manufacturers or they go down, because there is only so much people willing to invest their money in a dream.
It is, but at least I would have appreciated some kind of writeup, instead of "We focus on high value-added data projects at rapidly growing technology companies." and "Our engagement process is very thourough" (with a typo) and "This is becoming a growing field for us.

> improving the products way outside of what competitors believed was even possible

None of their competitors have said anything Tesla has done is impossible, merely that it's been (and remains) unprofitable without crazy VC funding that Tesla is tapping into.

> by iterating crazy fast on their ideas -- something that conventional car companies will not be able to do

On the flipside - did you ever hear of conventional car companies with the kind of problems Tesla has, where they've overpromised/underdelivered on production rates by 20x - 30x? And they're stuck on elementary things like they don't know how to automate welding metal bits together?

> by showing they can maintain exponential growth until they are dominant force in the market

Can you show me the numbers supporting that claim? Tesla growth e.g. in number of vehicles sold from 2010 to 2016 isn't very different from the total automobile market in the US, which also grew almost 2x in the same period. If you look at it quarter by quarter, it's obviously linear growth for each of their models (Model S, Model X). And their total numbers for cars sold, revenue, income etc. remains at the sub-one-percent level as compared to GM, Ford etc.
Very interesting. I've felt this as well. Even bottled flat water, doesn't seem to hydrate me as well as a carbonated mineral water (e.g. Perrier or Pellegrino). I wonder if this is placebo or if there is some other meaningful effect happening.
VCs are a flaw in the system.

It costs almost $0 for an engineer to build software and yet VCs have somehow managed to artificially raise the barrier to entry and got huge paychecks for themselves in the process.

If VCs did not exist, I'm certain that we would have all the software, websites and apps that we have today except that it would have cost society much less to get to that point... Also maybe these apps and websites wouldn't be the terrible morally bankrupt profit machines they are today.
On the other hand, good press about tesla is in the interest of Elon musk and tesla shareholders. Wars between bulls and bears on controversial stocks are waged largely in the press
Not worried about it. First, we're not really "boutique". We don't dress anything up. It's all used machines and old bags. We charge more because that's our real cost plus a small profit...

I figure thing happening in food right now is not so much a trend. Food prices are artificially low by historical measures. As the subsidies granted by cheap oil-based fertilizers goes away and diesel-powered harvesting starts to be less cost-competitive, the prices will go back to historical norms. People want the industrial system to stop cutting the corners they have been (believe me they tell us) so we make profit from those who are ahead of the curve.

The way I look at it: normal food has been getting more expensive over the past 100 years and is now considered "boutique" by some. There has been a fad in cheap food that is starting to wind up as it is no longer possible to maintain. It's time to get in front of that before your food costs rise. More importantly it's time to start teaching kids how to do it too as they're going to really be in the post-climate-change world where viable solar-powered food is the most valuable thing to have a startup in.
Unless I'm missing something I don't think so. The case has mains voltage in and switched mains voltage out only, to touch the low-voltage bits with the weird ground level you have to crack open the case. Which is kind of encouraged by open design that's easily hackable, but something that falls under "well, if you do that you're supposed to know what you are doing".
