Weft - http://weft.io - Cambridge/Boston, MA (office is in central sq.) -- LOCAL ONLY (no remote)

===========================
====== What we do =========
===========================

We're the single source of truth in logistics -- we track every boat on the water, every plane in the sky, and every truck on the ground so that we can know everything that's going on in the logistics world. We do a lot of analysis and optimization, too. We’re working in the largest, least sexy, most invisible industry in the world — 90% of everything has been on a ship at one point in time.
The problem -> Lots of inefficiencies in the supply chain! One of our customers spends $400mm/year shipping empty containers, another spends $80mm/year on late fees. Lots to optimize!
How we fix it -> We track everything in the supply chain and make predictions and recommendations as to what our customers should do!

===========================
===== How we do it ========
===========================

Web/data stack -> clojure/scala/python + postgis/redshift/redis/rabbit + ruby on rails + hadoop/EMR (we’re a SOA shop)
Mobile -> iOS, android, mobile web
Algorithms -> a dizzying mixture of oldschool and newschool techniques... think ML, Neuro-AI modeling, and statistics

===========================
====== And the rest =======
===========================

We've got some very interesting partners and customers (ranging from CPG companies and telcos to enterprise software providers to regional and international logistics companies). We also have some top tier investors (a16z, atlas)!
Looking for:

- Big Data Tech Leads (framework and language agnostic, think DevOps meets InfraOps meets Big Data meets Data Science)

- Lead Full Stack Senior Engineer (framework and language agnostic as well, but we're Rails+Angular+Foundation and Node.js too)

- Just really smart people who think they might want be able to contribute and are interested in what we're up to!

If this sounds interesting, please shoot us an email at mike@weft.io! We've also got detailed job descriptions posted on AngelList (https://angel.co/weft/jobs/)
I believe everyone can make mistakes and deserves a second chance. It's not because you've done something bad in the past that you are forever lost.
I don't get this article. The battery in a Tesla Model S is literally a huge array of Panasonic flashlight batteries. It is an off-the-shelf catalog item you can order from Panasonic. Admittedly, you should probably have prior arrangements before ordering millions.

The central insight of the Tesla founders was that people really will pay $85000 for an electric car. The other auto makers didn't believe that.

SQLAlchemy is awesome, but it's an order of magnitude more complex to setup and configure than the Django ORM. With Django you get the integration with migrations, a system to spin up and tear down test databases, less boilerplate code required during model configuration (like not needing to specify the name of the database table), etc...
I simply cannot wait for the biography. I really find this story to be more interesting than any other in similar vein.

I really want to know did he start out with this plan or did he simply see batteries as being the easiest thing to improve on by multiples compared to alternatives. Perhaps better said, there are many parts to a car that could be innovated on to such great improvements but the battery in electric cars really needed to be improved by an order of magnitude to make them competitive with petrol power.

Was it that fact that drove him to move into the global space using batteries or was moving global going to happen with whatever he needed to do to improve over the competition so much?
Yep, like

My point with this post is that their business hinges on Battery production and tech more than any other component, and thus the lead they've created in this space matters more than any of their other innovations.

But you're right, their execution on multiple fronts is truly unreal.

Can't think of a better response than this.

I'm only mildly supportive of Certificate Transparency, but would definitely like it to "have its day in court." Hopefully CNNIC deploys CT and reapplies to Google for inclusion, but either way it will be interesting. I love it when things get put to the test.
I think that's a very idealistic thing to believe. But I'll bet you wouldn't wager your retirement savings on a financial planner previously convicted of embezzlement, your children on a nanny with sex conviction, or your life under the scalpel of a doctor who had done time for criminal negligence.

And if you would, good on ya. You can be the one to give everyone second chances.
Article fails to mention that Tesla has actually stated that it intends to market a home battery and that many believe this is the product that Elon referenced recently.
The photography in this article is gorgeous, the material is great, and the presentation is almost flawless. I continue to be impressed with the output on Medium - I wonder how they manage to get outlets like Mother Jones to grace them with such awesome content.
It's telling to me that the former editor left to go to Bloomberg. Bloomberg represents, in my opinion, a more sustainable approach to news - they want their news org to break even or make money, but they don't expect it to be a barn burner and recognize that having the news sources internally gives them an advantage in their core business - their terminals. Dow Jones is taking a similar approach. With this approach, they can afford to pay for excellent journalists while not being a slave (completely) to the advertiser. It keeps them out of gray-areas like native advertising as well (although Bloomberg may have that as well).
The article is specifically about round-tripping between base-10 and base-2 floating point because the precision of floating point is a very real issue if you're doing conversions. This is e.g. one of the reasons why decimal fixed point is preferable for many types of operations.

Fair enough that the title leaves it ambiguous, but the ambiguity is resolved in the first sentence of the post, and further clarified in a lot of detail over the next paragraph and a half.
What does "many crops are badder" have to do with anything? California produces and incredible number of almonds, and almonds are incredibly water intensive. That's why they are being "picked on".
Vicky is going away to college in Springtown, but will live in an off-campus apartment in Livingston. The two locations are 2 inches apart on a map of the area; the actual distance is 34 miles. What scale does the map use?
From the quick searching I've done, I think that Django predates SQLAlchemy by nearly a year (July 2005 and May 2006 respectively).

Alchemy has a lot more power behind it, but the Django ORM is (arguably) easier to use for the majority of web use cases.

I had a hand in opening up the Django ORM with the introduction/formalisation of Query Expressions (https://docs.djangoproject.com/en/1.8/releases/1.8/#query-ex...), and others are doing significant work in cleaning up the ORM internals so that more complex features can be layered on in core and by users.
From the original part: "MCS Holdings on the basis that MCS would only issue certificates for domains that they had registered"

I don't understand why this would be allowed. Like, doesn't this break the entire concept of a CA if the CA will allow third parties to issue certs? I understand the need for corp MITM but that's best done by pushing out your own CA. And I understand the desire for a company to have its own self-managed CA system that's publicly trusted. But that simply cannot require the CA to put any trust into the other company; there's gotta be technical measures. That's why I'm confused as to why it matters if an HSM was used or not. Can someone enlighten me on what's going on?
Things like Facebook's Chat heads only work fully in Android (basically Messanger chats show up as a floating bubble no matter what app you're in[0])

I also like being able to configure my homescreen and having different keyboards (though the latter's shown up in iOS now)

There's some feature differentiation for sure, though iOS has the advantage on some things (I would kill for fingerprint unlock)

Yeah same here - reminds of me of its close cousin, PureData.
I believe Chrome will report back when it finds an improperly issued certificate.
I think that in the medium/long run google will, at least, add a new language officially supported and a bit more modern that the pseudo-java5 they are using right now. I mean something like what apple made with swift. Also considering google is already working on Go and Dart, there could be already something in preparation related to them.

So we are going to inconvenience the largest population, smallest demand base? How is that low hanging fruit? Even if the cities disappeared, and thereby California's population, there would still be a water issue from AG alone.
Totally ignorant of the tech here, but could they now do Netflix for Batteries? $9 / mo. gets you all the AA, AAA, D cells you require?
Meat consumption is a hugely unpopular topic. Take just this HN thread for example. There is way more discussion on crops like almond, than on meat and dairy industries. Meat and dairy consume way more resources than any crop/food grown for human consumption.

We can water our lawns less, and take showers once a week. It will not make much of a difference until we eat less meat. Same goes for sea food too. We are literally eating some of the fish species to extinction - it is just sad.
I paid for it and use it every day.
And there's some deal with Panasonic for the Gigafactory as well — it sounds very much like it'll be manufacturing stuff that's basically Panasonic IP to start with.
You say electric car like it's some souped up Prius (I own a Prius).

The Tesla Model-S is an amazing vehicle that's not only electric but amazing to look at and drive.

As an aspirational status symbol it's got a hell of a lot of cachet 3 years after it's introduction. That's a feat of product marketing and engineering.

IEEE 754 Floating point numbers should only be used where you can tolerate rounding errors. Even if you have enough precision to do base conversions, actually doing math will frequently introduce rounding errors.

You can either be very careful to avoid the many cases where this can happen, choose a different number format (fixed-point, decimal floating point, numerator-denominator, arbitrary precision mantissa binary floating point, which one depends on your problem domain), or use units that let you work in integers (equivalent to fixed-point, but easier to explain).
If you sort this site by price http://www.snapdeal.com/products/mobiles-mobile-phones/filte... you find the cheapest smartphones are about 1500rs. That's about $25 (according to Google). Most of them run Android. Though, once Windows Phone 10 comes out, I'd be interested to see if that's a better UX at the ultra-cheap end of the spectrum. Nevertheless, Android is currently the OS of choice at the low end, wherever you draw the line on acceptable UX. And the latest and greatest Android is available for about 4800rs, or about $77, running on a quad-core SoC.

As for how that's done, it's because Android can aggressively "swap" (really serialize and reconstitute)background components out of memory, and it can do the same to whole processes. You can actually watch your Android app instance switch PIDs, as it comes back from having had all the components, and the underlying runtime instance, killed. Now, there are some fat slovenly apps out there that might not be happy with life in a very limited machine, but I bet those 1500rs phones push the minimum specs pretty damn hard.

> The battery in a Tesla Model S is literally a huge array of Panasonic flashlight batteries. It is an off-the-shelf catalog item you can order from Panasonic.

Um, no. Viewing the battery of a Tesla Model S as just a big flashlight battery misses the whole point of what Tesla is doing.

A flashlight battery does one thing: it discharges energy until it's empty. Even an ordinary rechargeable household battery only does two things: it recharges, and then it discharges.

The battery in a Tesla Model S, OTOH, is continuously computing whether to charge or discharge, how much to charge or discharge, what its current state of charge is, how to manage charging and discharging to maximize its life, etc. And it has to do this in a constantly changing environment--a car that is traveling at varying speeds over varying types of roads. (Doing it for a home battery is actually easier, in a way, because there is less variability in the load.)

This sort of technology is absolutely critical if batteries are going to become significant in our energy budget on a large scale. The energy storage medium of the battery is only a tiny piece of the whole picture.
A solution to future student debt
Www.villagescholarships.com

Rising tuition costs and student inability to repay incurred loans is leading to what many call the student debt bubble and like all bubbles it’s only a matter of time until it bursts. This burst will force many colleges to close and is anticipated to be similar to the mortgage debt crises. Many see the recent announced closing of Briar College as a sign of what’s to come. One solution being called upon by many experts is the need for individual institutions to increase available funding to provide to their students. Options like Village Scholarships is another viable solution. Village Scholarships will not only help students pay for their higher education but could help to maintain the steady presence of colleges and universities throughout the state of Colorado and throughout the United States.

Higher education has not yet caught up with technology, especially in the scholarship financial industry, and I wanted to bring the speed and efficiency of technology into that field. The current government and private student loan programs are automated improving speed and efficiency of financial disbursement. Currently, the student loan debt is over a trillion dollars, and over 70% of students are graduating with student loan debt on average of $30,000 or more. Full scholarships are awarded to .3% of students and athletic scholarships only .7% leaving out 99% of the student population. Of all awarded scholarships, less than 50% of each come from institutions or government, while less than 5% come from private scholarships. The cost of a college education has increased exponentially over the past decades, yet funding outlets and opportunities remain stagnant or have declined. Village Scholarships are a "game changing" peer-to-peer scholarship automation service that will not only revolutionize how individuals pay for college but how scholarships are administered.
