What would failure look like? Worst case outcome to me seems that they would just take longer to get to their goals rather than not achieve them at all. They have enough money in the bank and no unsolved technical issues - it's not black hole physics. I mean they've delivered cars already. They just are slower than expected at scaling up.

> It provides me with a certain comfort

Does the fact that some idea provides comfort have any effect on whether that idea is actually true?

If I find the idea comfortable, say, that I will inherit a million bucks next year, does that have any influence on whether I will in fact inherit a million bucks?

> I'm not too proud to accept placebo benefits, if that's what this is.

But

(a) does the possible existence of a placebo effect for some belief actually make the belief true?

(b) what have you done, if anything, to ensure that there aren't negative side effects to your possible "placebo treatment" that might outweigh the benefits of the placebo? Analogously to how responsible medical practitioners should not prescribe a placebo if the placebo treatment conflicts with treatment of a more fundamental condition, even if the placebo would have some positive effects.

Amusingly, history is showing that there are as many rewrites from type systems to no type systems as the reverse. Consider all of the things that are getting redone in the javascript world.
I don't get why people say this. Vue and Angular 1.x are only similar when you're comparing the templating engines. But how much of the work migrating to React or Vue actually involves porting the view? I think that's not a very substantial amount compared to the application logic.

I've worked with all three, and I would say that Vue and React are for more similar than Angular and Vue.
Yikes. So which of the other 3 listed methods do you prefer? Or something else?

Also, I think you’re somewhat confusing whiteboarding and being interviewed by an egomaniac. If someone is a total jerk, I imagine any interviewing methodology will suck.

Initial quality problems may not arise. They will definitely arise. It's a brand-new model, with brand-new (To TESLA) manufacturing processes - there will always be problems in this situation.

What they should hope for is for these problems to arise sooner, rather then later - lessening the cost of recalls.

They used his work on two separate occasions. The 2nd time was after they knew they had used his work illegally in the past. At that point it's a pattern of behavior. They were given the opportunity to fix it themselves (taking down the pics is only part of fixing the issue, not repeating the theft is the other part) and chose not to. How many chances should they get? What motivation do they have to change the behavior if there are no repercussions?
> The Tesla is way superior to any other electric car on the road.

Except that it mostly isn't on the road at all!

Cost per mile of range is a nice way of getting lower numbers for the Tesla, but it's more out of pocket.

The model 3 has a longer range, is faster, and is overall much sexier, but it costs for model 3 users to use those superchargers, and you can get a Leaf or Bolt today.
Well, I guess it's apparent now that it fell outside of my immediate observation. I would be curious what the risk calculus on that decision was. I think it still fits in to the same narrative that I was building though: Tesla seems like they want to bring everything in house while Apple has only brought one piece, the jewel of the system, in house.
Well, when everyone that understands exactly how the surveillance of the modern internet works has a hand in building it, don't be surprised where there's no one left to make the well informed case against the surveillance apparatus.
That's true, but I dislike "essential" third-party projects anyway. Part of the reason I like Vue so much is because of the "official" Vue + vuex + vue-router combo (for React you have to use third-party libraries for state management and routing).
That's basically my biggest problem with fish. If I could get 99% of the functionality with near complete language incompatibility with bash, that would be ideal.
I think the important distinction-- and the reason that I never got very far in Forth myself-- is that with Forth, you don't have the pile of tools and raw materials, but instead a forge and some ingots of various metals. You really do often end up rebuilding even things you'd normally consider simple library functions in most other languages.

One of the tricky things about shells is the interaction between fork and pthreads. For example, if you fork while another thread holds a lock, you risk deadlock.

node uses pthreads for certain asynchronous operations like stat(). How does Closh handle forking when there are multiple threads?
it's to bad that there isn't more inspiration from the past 20 years of OS design. A capability based security/object management interface would nice.

Agreed and seL4 comes to mind. It's capability based, quite fast and secure. For that matter, it's also quite small.
Didn't know that.

If you are doing some kind of intense annotation probably your most important thing is having an output format that supports the annotation you want to do -- not necessarily supporting any.

I have been thinking about universal annotation and the formats that I find the most interesting are PDF (because so much content exists in PDF) and HTML (open, easy to work with.)
If what you want is a Tesla 3: yes, probably. If what you want is a(n electric) car: no.
Off topic, but we can't. All the readily available sources of energy have been used. As someone else said, this is literally the last great civilization. Best not screw it up!
Anyone have a link to watch the keynote?
So really, Shazam is the WhatTheFont for music.
If Tesla goes under what happens to long term support for their cars? Don't Tesla owners depend on a lot of Tesla services? Subsidized charging stations, sending it in for maintenance, etc.?
Their burn rate is incredible. If they run out of money and nobody is there to give them more, they file for bankruptcy.
Exactly what yoavm said. The pipelining that shell languages do allows for more complex and more arbitrary data transformations. I feel that doing this in Python would be difficult, but I'm not very familiar with it. In scheme you can do something like this:

(define (pipe . exprs)
(if (null? (cdr exprs))
(car exprs)
(apply pipe (cons ((cadr expr) (car expr))
(cddr expr)))))

(pipe '(3 4 5) (lambda (x) (map 1+ x))) ;; '(4 5 6)
Retain.ai | Onsite | San Francisco | Founding Team Engineer - Generalist or Full Stack | $80k - $120k + substantial equity

At Retain we help companies understand customer interactions across teams, tools and applications. Our solution integrates with the day-to-day tools companies use (e.g. ticketing, calendar, collaboration tools, CRM apps) to obtain customer interaction data. Retain enables data driven decisions in everything from pricing (by increasing revenue on expensive customers) to product roadmap (by focusing on features that have the largest impact).

We’re venture-funded and this is our first engineering hire outside of the founding team. This is a true generalist role, so the expectations is someone who is willing to grow and adapt with the role. Substantial responsibility and equity upside. Web and data experience are likely to be biggest assets — we’re on AWS and Rails with the usual accoutrement but ultimately tech agnostic.

Requirements
* You are nice, smart, and action oriented
* At least 2 years experience building web applications with modern technologies with solid understanding of databases
* Some experience with big data frameworks, analytics, ETL, or integrations is a strong asset

Each time you encounter a new concept, search for that too.

Search for "beautiful matlab code"

Learn from others. Aggressively search for open source matlab code bases and read them.. look at their structure and try to understand why they are doing things the way they do... email the authors and ask them questions.
It sounds like they are struggling. Hopefully they can pull it together and turn things around.

VMware to Acquire VeloCloud, Doubling Down on Networking
VMware has struck a deal to acquire software-based networking startup VeloCloud Networks, according to a person close to VeloCloud, in a move that is likely to escalate VMware’s rivalry with Cisco Systems. Terms of the deal couldn’t be learned.

For VMware, a data center software company, acquiring VeloCloud is a sign of its commitment to becoming a major networking player. VeloCloud’s technology, known as software-defined wide-area networking (SD-WAN), routes traffic to ensure that applications including voice and video running in data centers deliver sufficient performance when users access them from a company’s branch offices.

We did some work on computing derivative expressions (goal is application to deep learning) for such tensor algebras. I was going to release it on arXiv in the next few weeks, but now seems to be a good time. Here you go (preliminary version):

https://github.com/surban/TensorAlgDiff/raw/master/elemdiff....

Our system takes a tensor algebra (we call it element-wise defined tensor) and outputs expressions for the derivatives w.r.t. all of its arguments. The expression may contain sums and the indices of the argument tensors can be any linear combination of the function indices (see our example for more details). It correctly handles the cases where an index does not appear in an argument, appears twice, appears as (i+j) etc.

Reading the post helps address a misunderstanding about misunderstandings:

>> Netflix uses React on the client and server, but they identified that the client-side portion wasn't needed for the first interaction, so they leaned on what the browser can already do, and deferred client-side React. The story isn't that they're abandoning React, it's that they're able to defer it on the client until it's was needed. React folks should be championing this as a feature.
So someday, Hypothetical Nation#1 captures one of Hypothetical Nation#2’s optically-guided missiles that uses a neural network to distinguish friend from foe. N#1 technicians download the network weights and use this to generate perturbatory paintjobs for their fighter jets, making N#2’s missiles recognize N#1’s planes as various models of N#2’s civilian aircraft. Before N#2 can refit their missiles with a retrained neural network, N#1 launches a massive offensive and decisively takes control of the Hypothetical South China Sea, or something.

Do I have that right?
Security Analysis of Telegram: 6.857 Final Project [pdf]
IMO, the two easy things:

- read other similar projects and understand how / why they work

- fix problems that you see.

If there are packages you're using from other systems that's often a very easy place to start with the first one... follow through all that code and see how it's organized.

With the second one, I'll say that it's really easy to put up with crappy workflows just because it is what you're used to. You have to not be willing to put up with the things you don't like in order to fix things. Use source control. Don't write functions that are 300 lines long. Think about the times that you have problems in your code and don't let those happen in the future.
>His point is that innovation is both something that we all want, yet something that is often best decided by the market, not by regulators or competitors. Perhaps the energy innovation that would benefit society most is not pursued because it's too lucrative to invest in solar.

As a generalisation, I think that solar "subsidies" are a two-part problem. First off, the government is refusing to price the negative externalities of greenhouse gas emissions (in part due to the republicans largely refusing to acknowledge the externalities even exist), which distorts the value of solar by implicitly subsidising fossil fuels.

Second, people acknowledge that solar needs to be made more viable and attempt to correct the market by adding a subsidy to solar instead of removing the subsidy from fossil fuels.

I think this exposes a fundamental flaw in common neoliberal ideology today - the notion that the way to remove market distortions is for government to do less, not more. This is clearly absurd, since climate change will cause trillions of dollars of property damage, and penalising property damage is basically the government's job.
Checkout Next.js (React based framework) if you want to worry the least about routing, and just default to a route per page model.

Next also makes it easy to do server rendering and/or pre-rendering of routes.
Preorders don't become actual sales until you ship the product. If Tesla can't ship cars fast enough they're going to have serious cash flow problems.

The pre-orders mean they could get some line of credit to help, but that will also cut into margins
It is a part of their core product differentiation. They can get better performance and longer battery life by owning the hardware design and OS design and being good at it.

Apple in particular understood lomg before competitors that battery life is an extremely important real world metric. Doing their own SOC helps them optimise that.
Nothing stops you, as a person wanting to get your code in, from signing the "individual" CLA and ignoring the fact that you work for a company, either maliciously or because you don't understand or don't know that your company holds copyright over the code you've written.

This happens; it isn't a hypothetical.
It's not an accurate summary though, see the sibling comment to yours for a better one.
Awesome!

They definitely seem to have hit a plateau in terms of demand which was declining before they started to slash prices in order to move inventory.

The S/X and are old now and the car market requires new models to keep sales going.

That combined with the approaching launches of other high end luxury electric cars does not bode well for future S/X sales.

The negative press on autopilot and failure to deliver on autopilot 2.0 could certainly be a factor as well.
At least part of the problem is that it looks so, so weird, and it's really tightly bound to models. This is like the most customized admin i've made and it's still pretty simple, but it sure doesn't feel that easy to reason about when you look at it (it's an admin page that lets you link a specific admin-page input to a model, then display it in a list that you can add to):

from django.contrib import admin
from django.forms import Textarea
from .models import *

# Register your models here.

class BotTextInline(admin.StackedInline):
model = BotReplyContent
extra = 1
fieldsets = [
(None, {'fields': ('message_type', 'text', ('template_text', 'example_text',), 'order',)}),
('Actions and inputs', {'classes': ('collapse,'), 'fields': ('action_type', 'input_type',)})
]
# readonly_fields = ['input_type_ptr']

class BotReplyAdmin(admin.ModelAdmin):
fieldsets = [
(None, {'fields': ('state', 'intent', 'context', 'description', 'next_state',)}),
]
formfield_overrides = {
models.CharField: {'widget': Textarea()}
}

list_display = ('state', 'intent', 'context', 'description',)
save_as = True # lets you save the content on screen as a new id

Hi, I just saw the presentation too, and it looks impressive.

I'm hoping that you can (at some point) write a language-agnostic library, so that your work can be used in many other development tools (which are not using C++). I suppose it would amount to publishing the documentation of the intermediate code you are already using. This would also save you the trouble of writing and maintaining a GPU back-end because other people could do that using your library.

Anyway, great work!
First companies that come to mind as plausibly fulfilling this would be Samsung/LG types. Not sure of an example of a company on a smaller scale.
I wonder how valuable that charging network will end up being long-term. With the Bolt delivering 238 miles of range, and that number likely to go up some more in the next few years, it seems like a fairly small niche of people that actually benefit from superchargers. Especially as the number of end-point chargers increases.

Which isn't to say that it won't be a valuable marketing tool, however -- range anxiety is definitely going to be a thing for a while.
Yes, but it’s fast!

So basically, the whole thing about Tesla being more a battery company than a car company that was supposed to help justify their valuation was bullshit. They don't even have the in-house capabilities to tell that the company that they contracted the work out to had screwed up until well after they were supposed to be shipping.
I don’t see how it’s inaccurate. The email was an honest communication from a DNC hiring manager in their Tech department. Potential candidates should feel that they will be discriminated against in their hiring practice and in their day to day interactions. We should apply the same standard to this racist we would if they were discriminating against black, gay, tran, women, etc.
Core sample from Indianapolis 500 track
While I agree that the Tesla 3 backorder delay is pretty long, I think you may be underestimating the time it will take before we see any subscription-based autonomous cars by perhaps a factor of 5.
I'm not sure if this is a sensible question, but what is the use of this compared to (say) an autodiff library like FABAD++ [1]? Is performance the main advantage, or expressive power, or something else?
