Fixing that for the summation terms and t-p subscript produces:

\Delta P_t = \mu + \sum_(j=1)^J \lambda^j S^j_t + \sum_(p=1)^P \delta_p \Delta P_(t-p) + \varepsilon_t

where Word doesn't realize that the terms after the sum should be the content of the sum. Word Help and the equation editor are thoroughly unhelpful in deducing the appropriate syntax of \sum.

What I eventually divined was that the syntax is state-based: If you type it out manually, it will put your cursor into the right position, and once you're done with _t you need to hit the right arrow key before typing the space and plus symbol. Copy-pasting the whole thing is different and does not work.

I mean, it's great that it supports an entry mode that's faster than digging through menus and clicking on symbols with your mouse. But it's still fundamentally different and, dare I say, inferior when the appearance of the equation isn't defined by the sequence of characters you enter (or copy-paste) but by the sequence of arrow keys and escape keys you hit while you type it in. This is exactly the problem with Office vs. LaTeX.

Well, I just bought OpenGL SuperBible and was eventually going to go about making a simple game engine from scratch and learn the linear algebra required for graphics engines.

Would anyone still suggest learning OpenGL/building a graphics pipeline or just proceeding on to Kronos's Vulkan?

ALUS RELEASES ALADDIN MUSIC VIDEO
The article is more focused on the opposition to the plans instead of a whole cost benefit analysis of the project. It's a short article and it can't be everything.

Also it's not like the opposition to it is unreasonable, it probably will benefit the community but it would've been a lot better if Amazon didn't get the tax bonuses and since they were going to build the second HQ somewhere anyway. You have municipalities paying 5b$ for Amazon to do something it was going to do anyway so while the individual location is better off the system as a whole just lost 5b$ in taxes. This really plays into the current trend where Americans feel like these corporations really have outsized power in the US politically and use it to get what they want (e.g. taxes, laws, favorible labor contracts) and as average citizens we have little recourse to do anything about it.
I wish I could find Hoisin for a dollar. More like $3-4.

And while that doesn't sound like much, again, when we're talking about buying a completely new set of sauces to make one dish, it's $3-4 multiplied by the 5 new sauces and condiments to be closer to $15-$20.

And yes, if I use those ingredients regularly, then they quickly pay for themselves, as the Hoisin sauce lasts like 20 meals and the price per serving becomes fifteen cents a meal. But at the outset, if I decide I want to try Orange Chicken and it costs $20 + the cost of meat just to get the ingredient set, it's alot cheaper just to pay $11 and order some from a Chinese restaurant, no? If I like it, great, I can make it again. But if not, I've spent more money than I needed to and am left with five bottles of sauces I'll never use again.

Case in point: I've got a recipe next week that calls for "dark soy sauce". I have no clue WTF that is or if it is sufficiently different in taste or texture that I can't just substitute my regular soy sauce in for the recipe.
Not to be callous, but if aren't already paying $3500/mo then you aren't paying NYC rents. If Amazon moves in, they'll just build another half dozen highrise apartments and rates will stay about the same.

NCR, a new Tech tower, perhaps something new around BellSouth, Metlife at 17th street... Atlanta has almost twice as many people as Seattle, and unlike a sleepy coffee town has always been dominated by corporate culture. Even if Amazon moved their whole company here, it wouldn't change the city that much.
When my family grew (2 kids) it became important to me to stop eating out so much. Mostly because eating out with a 2 year old is torture. So I started cooking at home every night. It's easy to do if you plan a menu for the week. I have some common items in the pantry, and I buy meat in bulk every other weekend. I'll run to the store on a weeknight to buy fresh fish, or for the occasional forgotten item. But more or less I just get it all done in one trip, I plan the menu around common ingredients, and I choose things that don't take hours to do. I spend $80 a week on groceries (cut out boxed up processed foods and your bill gets cheap)

Families have been cooking dinners for a long time. Nothing new here.

CNCF to host NATS as incubation-level project
I've been trying similar-style videos on advanced data analysis/visualization since such screencasts are an unexplored area (my most recent video using Stack Overflow data: https://www.youtube.com/watch?v=6OeyTfp7eq8) but there are a few snags which make it less accessible for anyone to do:

1. It requires subject preparation to avoid going off on a tangent. (in the case of the video above I cheated and use prewritten code, and the video was still 30+min long.)

2. It requires specialized software and hardware that's not free. (good recording software + good mic + good webcam are $50-100 each)

3. It requires good hardware preparation too (e.g. precise placement of the mic and good light for webcam, so I couldn't record at night)

4. It requires time for editing (unless in my case you slap on background audio and call it a day)

I bought a new mic since I was unhappy with the audio quality in that video, and am taking steps to refine video focus.
To be fair, for New York (where Blue Apron is based out of) it actually makes some sense. Grocery shopping in New York can be (heavily depending on where you go) a taxing experience. Especially in Manhattan.

Space is expensive, so stores often have pretty narrow aisles in order to cram in as much as they can. You're almost always blocking people the second you stop moving for any reason.

Trader Joe's is so popular that it's not uncommon for there to be a line just to get into the store. The checkout line moves quickly, but because it's so large you'll still probably spend 20-30 minutes waiting in line to check out.

Anyway just shining a bit of light on why people might hate grocery shopping. I still think grocery delivery services make way more sense than something like Blue Apron, though.
> Everyone says that a powerful GPU is needed to drive this thing, but I don't think that's a must.

It is not a must, but it is a mostly. Most people want something approaching realism by default. Stylism is okay but it isn't the primary use case.

The video game sales show this. Top selling games are mostly ultra realistic, Witcher, Call of Duty, Modern Warfare, Battlefront, etc. Yes there is Nintendo's low end strategy but most are ultra realistic.

They are very, very good. I've owned every major HMD since the DK2 came out in 2014, and I would say the Samsung Odyssey is the best one to date. The inside-out tracking is fantastic and just as good as Lighthouse (in practical usage, not theoretically). When you consider that there is no setup involved, it makes it a no brainer that this is the way forward.

If the person already knows markdown, Pandoc is a great option [0]. I find it really useful for creating pdfs. I haven't used it to create official documents that often, but I have used it to create Beamer slides and it was a very smooth experience. If you're an advanced user and you want to do something LaTeX-specific you can just write LaTeX inline and Pandoc will accept it.

Honestly, I don't have a problem with cheap, plastic toys.

This is something my wife & I don't see eye-to-eye on. She favors things made from wood, tend to be more expensive, etc. I personally don't care. At this age, kids are hard on toys. Their change and they might play with a toy for 5 minutes & the never again. All the more reason for something cheap & inexpensive.
It seems like something Whole Foods is missing out on. There's a local Whole Foods-like store I've swung by in town that carries their own kits.
It’s important to speak up like you did. Europe has been used to torn local laws despite the citizens’ will on topics that are not universal (as opposed to universal values like corruption or the the voting system). Examples nowadays are topics that should be left to the people to determine, like abortion (Poland) and immigration (the 4 slavic countries). EU’s constant and reiterated push to disobey people’s will is costing us UK, Italy, Poland, the 4 slavs, Austria, and it’s only a matter of luck that France’s Le Pen failed her debate in an epic way.
My understanding is that Neanderthals are now classified as a sub-species rather than a distinct species. So instead of Homo Sapiens and Homo Neanderthalensis (sp?) we have Homo Sapiens Sapiens and Homo Sapiens Neanderthalensis.

It's not entirely unlike dogs and wolves, which can interbreed fluently. There are dozens of subspecies of Canis Lupus (red wolves, gray wolves, etc, etc), and one of them is Canis Lupus Familiaris, the domestic dog.

The smart contract has a method called updateState that allows a privileged address to update the brackets. That’s essentially an Oracle.

Aside: in the future where smart contracts are broadly usable, there needs to be some way (even centralized) to identify who’s trusted in such a contract and why you should trust them. In a normal office pool, it’s just Dave from accounting who runs the pool, but on the block chain that breaks down.

I'm wondering if this (these meal in a box services) is just one of those wrongheaded approaches. There's some saying about "Cheap, good or fast: pick two." And it seems like services like this are shooting for all three or something.

Yes, if you could do all three, sure, people would like to get that. But I don't see how there is profit in it. It seems like the target market is people who don't have time and energy to cook and don't have money to spare either. It's like they are secretly trying to solve the problem of the harried, overworked, underpaid 99 percent. And that's not really a business model. It's more like something that needs to be addressed by charities or government policy.

Highly-Anticipated Lightning Network Goes Live
Probably not many. The most recent SO developer survey said only 20% of respondents thought responsibility for unethical code fell on developers, compared to 80% thinking designers/managers should be responsible.

That's globally. I imagine the sense of responsibility decreases in ethically-gray areas like nation-state warfare against adversaries, and among developers working in strongly hierarchical, military(-esque) environments, for autocratic regimes focused on destroying national/ethnic/religious enemies (as this appears to have been done by).
I don't know what Spacemacs does exactly or how it differs from classic Emacs, so I can't really estimate the amount of work required to get it integrated.

This paper came out and changed the game a few years ago. It's called scratch theory and the front edge of the stone scratches tracks for the back edge to run along.

This is something I've been told when I worked for a hedge fund that had an office in Tokyo: Japanese regulators can raid you, download all your information, and that information can somehow end up in the hands of your rivals. It sounds like regulator raids can be used for corporate espionage and it can happen quite arbitrarily. I don't know if it is true but the fund certainly believed in it enough to setup a whole separate network in Tokyo that was not connected back to the network in the US. Everything done with the US was done via remote console.
What? I don't get any of either those assertions. People should be comfortable with who they are. I don't think pride is necessary, but also unnecessary and probably detrimental is to feel uncomfortable with yourself, be that anything, in this case ancestry.

> The council are able to reject parliament amendments and get the law passed anyway.

This is false. In most policy areas, if the council disagrees with the parliament's amendments, the proposal goes through a conciliation process. If the council and parliament don't reach agreement there, then the proposal is rejected. Thus, parliament has the power to reject almost all legislation. I wouldn't call that powerless.

Regarding the efficiency though, I would think (even disregarding new users of LaTeX) it would really depend on the length and content of the paper.

For longer papers with many formulas I'd pick straight LaTeX any time. Beside the formulas and look, this way once something looks good, it probably won't break in many unforeseen ugly ways when stuff is changed or added elsewhere. This in my experience is not the case with word processors, where you really need to review the whole document after any edit. Plus, working with text in a text editor is so much more efficient and enjoyable.

For things like slides and notes though, particularly when there are a lot of screenshots/graphics/tables/etc. in proportion to text, it's somewhere about 50/50 between Word and org-mode, which I then compile into pdf through either LaTeX or html. But I have accumulated a lot of templates and customization for the latter option to work well; without them, I would just be using Word.

Another factor is whether, and how often, it is going to be necessary to update the document with changed figures/tables/etc. This depends on how they are generated: if they come from an Excel spreadsheet, things work much smoother embedding them in Word; if they are generated by some code running, it's much easier to have the LaTeX document pick them up.
SBCL is great. I use it often.

I don't think the proposition that better tech wins passes the laugh test. You could argue that I'm a cynical old curmudgeon, though. I've been writing software for a living for thirty years now.

It's not about hackers being smart enough to see Lisp's advantages. It's about them (1) being the sort of programmer who prefers programming-as-teaching over programming-as-carpentry, and (2) getting enough exposure to live-programming environments to see what the deal is. The important advantages are not immediately obvious. They're whole system synergies, and it takes time and experience to grasp the nature of stuff like that, regardless of how smart you are.

Plus, maybe there are just more carpenters than teachers.
I get the differentiation between the city and it's residents. My comments were more in response to the overall financial benefit of the city and that they aren't just "giving away" money that can be used elsewhere. Likely these costs are offset via increased revenue elsewhere.

The idea of high-income earners driving up costs for everyone may be true as well. I don't have enough background other than anecdotal evidence to say one way or another though. Looking at price increases and any benefit changes to low income earners / low income migration from the area would be an interesting study once Amazon HQ2 gets off the ground.
Is that true? Do we really not know how ice skates work?

The assumption that political leaders invariably make decisions that are the best for the general public is not one borne out by evidence.

> It isn't this zero-sum game

Amazon is going to expand, right? Without a doubt, and regardless of what cities do, Amazon will expand. Therefore, cities offering tax breaks is just a transfer from the general public to the shareholders of Amazon. It's not zero-sum, it's negative sum, as far as the public is concerned. It's monopoly rent.
Do you really think a single simple metric like EEG would tell you much about musical preferences (not mentioning type of music to synthesize) given 100B neurons in average brain? For the first part you could try a RNN in an hour; not sure it would give you any meaningful results though.
Additionally, being "stuck" pointing straight into the wind isn't a situation where you are stuck with zero velocity indefinitely. The wind is forcing you backwards, and the arrangement of the rudder and keel/centerboard is unstable for going backwards without changing direction. Even if you don't know what you are doing you'll generally point one way or the other enough that you can then fill your sails again and have more normal control.

Ways to make this faster include pushing the main sail on a small boat out to the "wrong" side, tightening the front sail on the "wrong" side of a larger boat, and positioning the rudder only a little off center so that the slowly moving water relative to the boat is less turbulent.

Probably the only time when it is an actual problem is when people are drifting into some obstacle. It seemed to take students a matter of seconds to regain control of their boat when they were surrounded by large expanses of water. When they were frantic, their intuition about what they needed to do when in a hurry prolonged their loss of control.
The problem I find with inside-out tracking is the range of motion. One of the most powerful concepts in VR is being able to do things with your hands when you are not looking at them.

Maybe they could do inside-out tracking on the controllers?
This wasn't "5 million total viewers", this was "5 million incremental Prime subscribers specifically attributable to a desire to view these shows because it was the first thing they streamed". It would be analogous to HBO counting the number of subscribers it has added simply because of GoT or West World, but not to counting the total number of viewers for those shows.
How likely are we to witness an occlusion of Sgr A, if one were to happen?
