With AT&T Fiber - 1000Mbps up/down for $100/mo - you get unlimited data. The slower plans are capped at 1TB, but you can add unlimited for $30/mo (or pay exorbitant overages).

For wireless I'm hanging onto a grandfathered unlimited plan. It doesn't allow tethering though.
>It's the same with Tesla.

Can you show you get this from? I see it repeated on these boards, ad nauseum, that Tesla is spending their "profits" on R&D and building infrastructure.

But in reality, you can see from their financial statements that Tesla's CAPEX spending is embarrassingly small for an auto company, and shrinking. They spent $2BB in 2018 and are on pace to spend half that in 2019. As a sibling comments states, their spending doesn't even cover depreciation of assets. For comparison, Ford spent almost $10BB on CAPEX last year, GM spent $10.8BB, VW spent over $12BB.

>If they wanted a profit, they could have one. They just don't want one right now.

You can't honestly believe this, can you? What are they waiting for? Why do they keep raising funds? Where is the money going?

"Past Performance Is Not Indicative Of Future Results".

I am not saying a recession ISN'T imminent - but to declare affirmatively due to a technical indicator that one IS in an environment which has differences from the past is equally egregious. This yield inversion is based on sentiment, not fundamentals (yet).

Also, suggesting folks buy long-term treasuries is literally following what the market is doing right now. Suppose the trade deal is fixed tomorrow and governments add surprise stimulus in the coming months. (by the way, you have a crystal ball as much as I do) If recession fears go away in a few months, those long term treasuries would lose value on the principal and you could very much experience capital losses (if you sell).

Also:

> Then when the Fed inevitably rides to the rescue, begin to unwind and capture the capital gains.

Are you suggesting you can time the market like this? There is abundant literature which says people can't. How are you able to?
Uncompressed, multi-language audio so publishers can ship one disc in all regions.

Microsoft supports per-region download slices, but I don't think many publishers take advantage of that because Sony and Nintendo don't support it.
That's a good point about AR. Then again, Google and Apple have been pretty active in pursuing these areas, going as far as to now include dedicated hardware to help with much of the AI/ML stuff required to do that well, and they both have enough money to buy almost any company that comes out with a great showing in that area.

If we got some dark horse contender that wasn't taken as serious for long enough to let it gain an advantage and/or was established or large enough that there wouldn't be a lot of pressure to sell, maybe. Nintendo/Sony/Microsoft are the current contenders for that in my mind based on that criteria (with Microsoft actually aggressively pursuing it). Any other company that makes a good showing is likely going to be someone else's next meal.
I'm pretty sure they've got a 25 cm offering as well.
I'm a PhD student in physics, working on CAST [1], a small experiment at CERN. That fortunately means I don't depend on other peoples' code too much.

With the C++ interpreter of ROOT you can run so called ROOT macros. They are basically just C++ files containing your code at top level in pair of `{}`. The "funny" thing is half the time you run a piece of code it'll work the first time. But then running it again will cause the interpreter to segfault, due to the mess of global state and the half baked memory management of ROOT.

And don't get me started on the usability of the ROOT classes. A huge amount of stuff is string based, so throw away your type checking guarantees. I mean why bother...

Since I really didn't want to continue working with ROOT for my PhD (after having used it before), I decided to ditch the previous data analysis code and start from scratch [2].
I decided to use Nim for it, because it provides me with a powerful language (on par with python for my purposes - aside from admittedly certain libraries, which I had to wrap), yet still being as fast as the old ROOT code (in fact faster for my data analysis, but the comparison is problematic).

Yeah, it cost me a lot of time to get "back to where I started", the code itself might also not be a shining example of perfection, but I learned a huge amount about programming and I understand every piece of it. It was totally worth it. The gains in efficiency thanks to Nim and due to the fact I know the codebase means I make up a lot of the lost time anyways.

So to any people out there who may be in a similar position, don't be afraid to throw out what you don't like. :)

>I suspect this is the emotional allure of revolution, sticking it to those who have been sticking it to you.

I think this view is too simplistic; many ideas of a better society are simply incompatible with change "within the system", since the system itself, they argue, inherently fosters the tendencies they're against.

>Real change that produces progress requires consistent engagement over many years (know your representative, etc), individual responsibility and personal sacrifice (start a community group and build relationships, etc.), and compromise.

Does it? Why? What's the evidence to back this up? Consider that, for example, not a single petition made to the English government through their own petition schema has actually accomplished anything. This "know your representative" stuff doesn't even apply to non-violent changes of power. Do you think Gandhi succeeded because he got to know his representative, or he was open to compromise on Indian independence?

>This kind of, forgive me for using these words but, self serving immaturity occupies the intellectual space and crowds out people coming to terms with what’s required for real change

The intellectual space is currently occupied by near-pervasive liberal egalitarianism, and liberal egalitarians suggest that the way things are right now (systematically) is just fine.

The truth is that your anti-revolutionary model assumes that the goals sought by would-be revolutionaries can be accommodated within whatever system they protest, but this is manifestly untrue, and the history of both violent and non-violent revolutions shows as much. It is also shockingly ignorant of revolutions from inside the system itself against the people - the industrial revolution being one (think of the violent enclosure movement in Western Europe on behalf of the State).

I like the idea of it -- kids battling parental controls; I learned a decent amount from my electronics/wifi (they just took the whole router to work) being confiscated, like picking doors with credit cards and setting up another old router found in the garage. At school, everyone knew about VPNs and proxies, to circumvent site-blocking, and cd-cracks to bring in LAN games on USB

Both TFA and your particular tales didn't amount to much, but the more intelligent the controls, the better the kid has to become to circumvent it :-)

The Links Programming Language – Linking Theory to Practice for the Web
Hey guys, maker here. I built Openship to manage the backend operations for my Shopify stores. I used to manage them using Zapier and Google Sheets, but after getting tired of staring at spreadsheets all day and wanting to optimize even more, I decided to learn React and build a dashboard and a marketplace as a Shopify app.

Openship allows you extend Shopify GraphQL API as well as route orders to different sources like ShipBob, ShipMonk, Amazon, other shops directly, and even custom 3PL solutions.

Our long term goal is to provide a sleek and intuitive operations dashboard for e-commerce shops that they can host and customize how they see fit. With this, we want to have a tightly integrated marketplace where they can easily list their inventory.
Yeah, that's just horrible. We're emptying the oceans at an alarming rate. If they want to do it right, they shouldn't allow fish either.

As an aside can I pose another physics car challenge to you that 100% of people I’ve asked get wrong?

You’re the only car at stop light waiting for the light to turn green. You look up in your rear view mirror and see a car bearing down on you presumably with a distracted driver. You know you’re about to get rear-ended. In that split second do you: A) Let up on the brakes and put the car in Neutral or B) slam in the brake as hard as you can.

The emulation there was actually a happy accident -- the MIPS processor of the original PlayStation was repurposed as the sound chip for the PS2. Sony realized during development that they could take advantage of the hardware for backwards compatibility for minimal cost.

The PS3 (Emotion Engine) and Nintendo DS (GBA cart slot) are the only consoles I'm aware of that have hardware only for backwards compatibility (although some games used the cart slot for pseudo-peripherals, such as rumble support or a guitar "grip").
A similar and very powerful narrative can be found in _The Half Has Never Been Told: Slavery and the Making of American Capitalism_, by Edward E. Baptist. The book is slightly problematic in some of its methods, but overall I would highly recommend it to anyone who was taught the public school version of US history.

Based on the filing the company awarded 42M stock options to the CEO earlier this year. The filing mentions a share price of $110 per share, so that's over $4B.

That can't be normal, right? That's 10% of the entire company. It's more than Elon Musk got for Tesla by a long shot, and that was already controversial.
Very clear explanation, thank you.

It seems somewhat curious they don't have to reveal when they would be contractually obligated to pay out?
Thanks. I really want to read these but NYT sometimes goes a little nuts with javascript.

Toshiba... why doesn't that surprise me.

I've had a couple of them, they've been some of the least reliable machines I've ever had. Even getting a set of nubs for the Trackpoint was an exercise in futility - three hours on the phone, followed by finding a local Toshiba dealer (local being a good hundred miles away), only to pay £45 for three clearly used Trackpoint nubs. That was my last new Toshiba, but I do have a Libretto 110CT for programming old radio gear (old enough that the programming software only runs on DOS or Win9x).

My last two laptops were both Thinkpads and I've never looked back. My battle-scarred and heavily-stickered (to cover the scratches) X220 has had a mountain of parts. Heck, I once replaced the DC jack on the table in a convention hotel restaurant, using a friend's iPad to read the service manual...!

The only thing locking down repair manuals and parts will achieve (at least for me) is to make me look at what the company's competition is selling.
I agree with this, also will we try to pass another tax cut to try to stimulate the economy. It seems to me should use tax cuts, large increases in government spending, and rate cuts to stimulate the economy on a "rainy days". Doing these things during a good economy seems foolish to me.

Yeah, I totally understand what you're saying. I know it's a thing - I have old friends with extended families that are like this.

I'm pretty sure it is a weird American thing. It doesn't help that you guys have seemingly super cheap fast food.

One thing that might be interesting to look at is - if fast food just disappeared tomorrow - imagine every restaurant below say $15 a head just was gone overnight, microwave meals disappear, etc - would there even be enough food? Would the local supermarkets have enough or would there have to be an adjustment period?
Good points.

> that doesn't mean there's a way to avoid it

I don't think this is strictly true, though. As you said, "Stock markets aren't the same as the economy as a whole". The financial part of our current economy seems to have an outsized perception/participation rate. If the rules of the game changed to reduce the appeal of financial activity, there might be less second- and third-order "betting on bets (on bets)" and less of the self-fulfilling prophecy you're talking about.

This may not be feasible in the world we live in: it would take a very different political climate, and of course there would be knock-on effects for society. But imagine that we turned our income tax rationale inside-out and policy shifted so that wages had very very low rates and investment income very high rates. Note I'm not advocating this, just offering it as a "what if".
I think the Germans and the Americans both looked at the question "How do you get a torpedo to sink a boat when they put armor on the sides where the torpedo will strike?" and came up with answer: Have it explode under the boat not on the side.

The Japanese just said - have a larger warhead. The problem for them was that you then need a more powerful motor to drive that larger warhead but they didn't screw that up.

The odd thing is that the Germans and Americans (but not the Japanese) mainly used submarines to sink lightly armored commerce ships not heavily armored warships.

> Companies exploit this relationship now by destroying their balance sheets and using buybacks to boost their relative market caps vs other companies.

Buying back shares doesn't increase your market cap, it increases the value of each individual stock since they now own a larger percentage share of future earnings.

It has no real effect because index funds will actually have to sell stock from companies who do buybacks in order to decrease their share of the company back to normal proportional levels.

This is also true. Back when I was drafting my then-company's Form 10-K annual reports, for just that reason I loaded up the risk section with a list of all the things that could go wrong, based on studying similar lists from the big software companies. It's sometimes known as vaccination or inoculation — "hey, we told you all these things that could make our stock price go south!"

(The danger with this approach, of course, is that if you inadvertently leave something out, the plaintiffs' lawyers will spotlight the omission and argue, "they LIED!")
A growing problem since Tim Cook took over as CEO seems to be Apple techs trying to slither their way out of providing service. I've dealt with a number of flat-out lies that I had to actually call techs out on to get my devices serviced. Examples:

I bought Airpods last year. When they were about 10 months old, it was December in NYC, where I live. It gets a little cold, but not that cold -- freezing point is about the lowest it gets, maybe a few degrees below that at night. When I ran with my Airpods, they started to shut off randomly on colder days (40 Fahrenheit or below) -- clearly a sign of an aging battery not providing enough charge. Particularly since they started working again when I took them back inside.
I brought them into the Apple Store, and the tech tried to convince me that "Bluetooth just doesn't work well in the cold" and that they couldn't do anything about the issue. I had to basically beg the "Genius" to replace them, which promptly fixed my issue.

My iPhone SE would become randomly unresponsive to touches after they replaced the battery. I had to come in 3 times, reinstall iOS without using a backup twice, and beg the Genius (again) to replace my phone because their touchscreen test "didn't see any issues"... because it was a spurious issue that wasn't present all the time. I only got it replaced becaused I lucked out and the issue surfaced when the Genius was trying to start a diagnostic.

They've also tried to sneak their way out of servicing my Macbook Pro for "staingate" (coating wearing off the screen, covered by a 4 year extended policy) because, and I quote, "it isn't that bad."

Apple stores have clearly been prioritizing margins instead of customer experience. Those of us in the know can usually fight our way around these customer hostile policies, but I feel awful for my parents, grandparents, etc. -- they've been bamboozled by Apple into upgrading their phones for issues that should have been covered for free, just because they're trusting of the techs. It's gotten to the point that I don't recommend Apple products to them because the in store experience has gotten so bad.

It wasn't always this way. I remember when the original iPhone first came out that they were much, much, much more lax about replacing things pro bono, both for laptops and for phones. It's only since ~2012 or so that I've noticed service went really downhill, which happens to coincide with some restructuring of the Apple Store.

I miss the old Apple.

Hopefully the pain will force voters to vote to make internet a utility, or cause home prices in areas with symmetric fiber connections to have higher values causing more homeowners to put more pressure on politicians.
> I'd just like to point out that the yield curve inverted in 2018 [1] yet here we are.

As pointed out in the article you linked, what happened in late 2018 was a small section (3-5 year treasuries) inverted. When people talk about yield curve being a harbinger of recession, they're usually talking about the 2-10 year spread, which is what the parent post referred to.

You may argue "things are different this time", but you shouldn't be comparing apples to oranges.
Are you in index funds? Take a look at what they did in 2008. The selling point is not "they only go up." It's "you can't beat the market."
