would it be too hard to do: send request to bank, bank checks, says it's ok and returns the amount to withdraw, the card reader already says "is amount $20.00 ok", just replace that with what the bank said it was authorizing, user wouldn't have to do anything else, but the real amount would be shown at the time of transaction not what the card reader was told
How so? The reasoning here is: If you're earning $50 / month, the 20% commission results in a $10 commission fee. Since Pro Account is $9.99 / month and Zero commissions, a user earning more than $50 / month (and we have a few users approaching $100 / month in Beta) would make the financially reasonable decision to pay the monthly Pro Account fee instead and then forgo any other commissions.
This might be a naïve question, but does anyone know if this is suitable for online classification tasks? All the examples in the paper ([2] in the readme) seemed to be for offline classification.

For benchmarks, we didn't want to complicate things with multi-process setup, the idea was to compare the raw performance of all drivers.

The largest Li-ion cell manufacturer remains Panasonic, the other owner of the Gigafactory.

The "Batteries" that Tesla builds are just a bunch of Panasonic cells wired together plus some smarts to distribute the load. I don't see Panasonic remaining Tesla-exclusive for an extended period of time.
I'm also an investor and love Tesla and I agree completely with this....

There are many companies doing solar/batteries. Some are large and very well capitalized like GE and Siemens. The only way you could consider them "the only company poised to take advantage of solar + battery" is if you didn't bother to look for any other companies:)

I like Tesla's future but in terms of solar+battery they have alot of competition and its not at all clear that they are even the leader.
On top of all that, there's the whole autonomous car thing that is going to completely shake up a lot of industries and hopefully produce massive profits as well. I don't think Tesla is poised to take as large of the pie here as some other players are a little further along, but they will be there in a big way too.

It makes it perfectly visible, to the person who receives your email. After that only your attached resume is printed or passed on to other decision makers.

Putting your "cover letter" in body of an email is anywhere from bad to worse practice, depending on the initial recipient of your email (hiring manager vs low level recruiter).

Using that logic, any posts here advertising a new untested product should be banned. That would include all product announcements from $Company. Infact, that would probably include reviews because they contain subjective impressions about "performance" and other criteria that nobody can objectively verify and "provide additional feedback to help parties decide if its actually worthwhile".

> The source you linked doesn't show a transfer from EBP fiber to EBP.

You are correct that no such transfer is explicitly shown. I don't know if it's done or not behind the curtain, but you may recall that I explicitly accounted for this scenario in my fifth paragraph of my previous post.

So summarize, EPB fiber's profit in itself is enough to pay for debt service regardless of if an internal transfer is made or not. Furthermore the money doesn't simply disappear, just because it isn't transferred. The profit is still there, regardless of how it is accounted for and where it is kept.

EPB fiber is making money, EPG's debt is being paid off (in advance I might add), EPG fiber is not being subsidized (the power side is) and cash is being accumulated.

No matter how you look at it, EPB fiber is both profitable and sustainable.

> Moreover, it's not the debt outstanding that matters, but the original capital investment.

Oh, so we are moving the goal posts now, eh?

Not being able to claim that EPB fiber is unprofitable, you are now instead taking issue with it not being profitable enough.

But, to address your original point directly, no, the original capital investment does not matter. Only and only the debt outstanding matters if part of the original investment was funded by other means.

It's preposterous to claim that an expansion of a project would have to produce returns twice; once on the original project and again in full when the project is built upon via an expansion.

> A real company would be expected to generate a return on the original $390 million that exceeded the weighted average cost of capital.

This is provably false.

If a company built a national network to serve it's own internal communications needs, it would then not be expected to show (additional) returns on that national network, if it later decided to build out a local network in one of the markets in order to expand it's business.

The company would only be required to show returns on the additional investment it made in the local market. Doubly so, if the company received a federal grant to build out the original national network.

> Having a big chunk of that money fronted internally without imputing an interest rate to it is a subsidy.

No money was fronted internally without any interest. EPB made out a $50M loan to EPB fiber which EPB fiber later repaid in full with interest.

EPB did receive a $111M federal grant to build a smart grid, which it did. The grant was not used to build EPB fiber's network. That capital was raised separately through a bond.

I'll also add there has to be some solar power generation tie in, eventually, to Space-X as well.
Note that certification could also include verifying there is a plan in place for whatever period of support is reasonable. (We could dig deeper on this.)

Configuration options are hard to support. Say for example a "power level" setting is exposed (how much power is consumed to provide the device functionality). But it is also the case that more power shortens the lifespan of the device. A general client can end up setting that to 100% but won't know about the consequent lifespan issues, or too low a level results in half the functionality being switched off. By robustness I don't mean malformed inputs etc, but rather what is done with valid values. A general client will be oblivious, but an in house could present only part of the power range (the rest behind an "advanced" section). Settings will also interact with each other in device specific ways (eg power would affect maximum volume for an audio device). Pretty soon you'll need a complicated highly featured description language for the settings, interactions, cautions, effects etc. Also would you want to take support calls if external tools have been modifying the configuration, given that a single support call costs the same or more than the profit on the device?

That all said, I see nothing wrong with someone publishing and maintaining a set of best practises. IMHO it is the route most likely to get traction and improvement in devices.
This is a good point. Sometimes it's hard to remember that the true innovation of Tesla was the battery. Once they had that, they built a car around it (I understand this is a massive oversimplification). But SolarCity probably helps Tesla continue it's biggest advantage for the future: the most likely Tesla for X remains Tesla itself.

That said, the conflicts of interest and pretty clear move to bail out a failing company still bothers me
With the amount of momentum behind him it would take a lot of upsets to derail the company. There's always going to be some wealthy philanthropist willing to bail them out so they can be included in the Musk biographies of the future.
Usually would agree, but I ended up staying for a few years (and a couple of retention bonuses) and I think it turned out to be the right decision. It was a tight-knit team and I think they only lost one person during the whole acquisition process, and that to a lucrative offer.
The body of an email with a resume attached is an explanation to the person you are emailing about why you're sending them a resume and what you want them to do with it, no more. If the company is bigger than 80-or-so people and the person you're mailing is a recruitment inbox, then they are not going to be particularly interested in anything the email says other than which job you're applying for. Your heartfelt explanations about why the company is the place where you have always dreamed of working will never make it to anybody who has hiring decision authority.
That's the "low road," (Tesla vs the utilities) but the "high road" (Tesla plus the utilities) is much more interesting imo.

The plan is to offer grid stabilization services -- voltage boosting, phase correction, and demand shifting/response -- by aggregating together home batteries, utility-scale batteries, and scheduling EV charging. These are all valuable services for the utility. The revenue from these would be passed on to the end customer, "closing the loop" in our current perverse residential electricity pricing.

What do I mean by perverse pricing? Ideally each customer would be billed based on and tailor demand to the real-time generation+distribution cost at their location on the grid (accounting for their individual line loss and utilization of their distribution and transmission connections), but this is far too complicated and prone to market manipulation. Even TOU pricing has an information lag from actual demand because of changes in demand and the rising percentage of renewable and distributed generation. And net metering is subject to the "solar death spiral" problem, which is quite real (though overhyped by utilities for their own purposes).

One of the big advantages to making their own inverters is that each one acts as a grid monitoring station, relaying voltage drop and phase lag information back to the mother ship. Their EVs can already do this as evidenced by their OTA rollout of charging software that slows charging when overheating wires (voltage sag) or arcing (voltage spikes) are detected.

In the not-too-distant future Tesla will have more raw information on the grid than the operators themselves, though obviously it's even more powerful when combined with their existing data. This combination can be done directly through data sharing or emergently simply by interfacing with the existing pricing system.

None of this is speculative btw -- SolarCity's CEO Lyndon Rive[1] and Tesla's CTO and SolarCity board member J.B. Straubel[2] have talked directly about these plans before.

You make a great point which is spot-on overall. I wouldn't go as far as saying "the car part doesn't really matter", though. Having a viable primary vehicle (pun intended) to drive (heh) your technology forward is important. SolarCity + Tesla Battery tech would be much harder to pull off if they didn't have a large in-house initial "customer" in Tesla cars. This will help them identify and solve technology problems, achieve economies of scale to drive down cost, and prove out the viability of these technologies in-market. And the requirement to sign up other customers on the battery side is alleviated early on.

Tesla's showrooms are also a great asset in promoting both solar and battery tech for the home, and the car is important in rationalizing the expense of these showrooms (at least for now) as well. Moreover, a very consumer facing brand and product in the car helps tremendously.

Anyhow, not to nitpick. You're right on about the overall strategic rationale and why this makes so much sense as a combination. But it's too far to say the car doesn't really matter. In fact, the car is a very important part of the strategy and especially of the nearer-term tactics.

>At the moment, I’m only targetting a tiny subset of the D programming language. The language comes with a runtime, featuring a garbage collector. It’s my first journey to the land of D-asm.js, and there’s no way I’m bringing the D runtime with me – especially if I need to port it to Javascript first.

This is basically why D is not a good systems programming language. Theoretical GC performance aside, barring a miracle, they will never have the resources to develop a high quality GC and even less chance to maintain high quality ports across relevant platforms (heck they couldn't even compile on mobile platforms until recently).
Obviously there are a lot of other companies trying to do the same thing. And none of those companies will be able to compete with Tesla's pricing on the battery side as soon as the Gigafactory is fully online. They will be producing a very, very large proportion of the world's battery capacity and have the scale to bring costs down way below what anyone else is capable of for some years yet. There is risk there of not being able to meet demand between panel installs and model 3 orders, but I think that's a good problem to have.

The panel side of SolarCity is a little less impressive, but the Silveo 360w panels are looking to be very competitive with other offerings in that range on price, though they will probably have lower absolute efficiency relative to the next-best offering that I know about from SunPower, and a large increase over most currently installed panel's wattage.
Easy: I currently have 619 unique passwords, all but two auto-generated and difficult to memorize (because they tend to be 40+ characters and as random as practical). I've had at least four websites on which I've had an account experience publicly-known hash leaks, and in zero of those cases, nor any future cases, is my password hash likely to be easily cracked, and in the unlikely event that it is, the combination or username/email + that password doesn't work anywhere else, so it's of little to no value.

I use 1Password, though, so I'm not storing my passwords on someone else's computer in the same way LastPass does.

The ease with which password hashes are cracked advances steadily, and I wish more sites would let me supply them with 80+-character passwords.

Whilst the current Tesla models might well be "luxury electric", the upcoming stuff is entirely in the same segment as Nissan, hence the reply to you.

Maybe you should read up on Sovereign Citizen stuff. It is literally gobbledegook, based on making up linguistic stuff like claiming that 'understand' means 'stand under [to make a contract]'.

While I don't have the links to provide right away, the "unemployment rate" in the US is around 6%, but to get to that number, a large number of people who haven't had a meaningful job for a long time and have "given up looking for work" are simply not counted as part of the labor force. Thus, in the US, labor force participation rates are at an all time low - directly in contrast to the low unemployment rate talked about.

A large number of workers are needed in the US to do low-wage tasks - pretty much so their employer can profit from their labor - and some of the issue is that illegal immigrants wouldn't be counted as part of the labor force (because they aren't supposed to be here), but in theory, they are displacing the opportunity for Citizens to do those jobs.

The issues are more complex than I describe, and they certainly will apply to skilled labor too (ex: nurses to care for an aging population). One of the major contentions is that companies, in reality, post jobs with requirements that are high (10+ years! X, Y, Z skills!) but offer a salary or compensation that is way, way below market value. This means that technically yes, the company can not find a qualified candidate to do the job, because they have targeted people who would be willing to do it for much less just to, well, have an opportunity to get into the US.

It is very backwards for the US to be "anti-immigration" as a general concept (it's the foundation of the nation!), so how the arguments get twisted make it hard to figure out in some ways. This explanation is simply my perspective using my observations and stuff I read, so it is not peer reviewed or anything like that!
