> What is the grease pencil?

The grease pencil is Blender's 2D drawing system. Initially, it's purpose was to allow artists to sketch scenes out onscreen, in much the same way that CGI artists a few decades ago used literal grease pencils [1] to draw on their glass computer monitors.

Nowadays, the grease pencil is a full 2D art system, allowing for hand-drawn 2D art to coexist with 3D assets or tracked with camera footage. The Blender Foundation made a short film called "Hero" [2] to show it off.

> How do I select all (UV) verticies?

On the bottom edge of the UV editor window is a menu bar. From the left, the menus are editor type (shown as an icon), "View", "Select", "Image", and "UVs". Farther to the right in that bar is the widget that lets you set whether you are selecting verticies, edges, faces, or islands. In the "select" menu is "(De)select All", and a label indicating that the keyboard shortcut is "A". (This shortcut is universal to all of Blender's editors (except the text editor, where it is Ctrl+A).

If you have anything at all selected, then "(De)select All" will deselect everything. If you have nothing selected, it will select everything.

> How do I select multiple via box?

In Blender, this is called "border select". In the same "select" menu I described above, it's the bottom option (the one nearest your cursor when you open the menu). It also has a universal shortcut, indicated in the menu: "B".

> How do I do numeric input?

There are two ways I can interpret this. One is "given a number box, how to I change the value"? There are three ways that you can change the content of number boxes in Blender.

1. Click on the arrows on the left or right sides to decrement or increment the value.

2. Click in the middle, type a value or math expression, and then either click outside the box or type "enter".

3. Click and drag the box, from the middle, to the left or right.

The other way I can interpret the question is "how can I specify the coordinates of a UV vertex"?

Once you have one or more verticies selected in the UV editor, you should see some properties and editing widgets in a tall rectangular area on the right edge of the UV editor window. If you don't see it, you can reveal it by either clicking on the "+" button near the top of that edge, by going to the "view" menu and selecting "properties", or by hitting the "N" key while your cursor is over the UV editor.

In the top of the UV properties shelf I just described is a section called "UV Vertex". (It's called that even when you are in edge, face, or island selecting mode.) It has two numeric boxes in it labeled "X" and "Y". These have the coordinates of the most recently selected vertex. Changing the contents of those boxes moves the selected vertex to those coordinates, and moves all other selected verticies by the same amount from their previous locations.

Whenever the market drops, I put more in. October - December, 2018 was tough, but I invested more. And it paid off. I had months where I've lost, then gained, more than I take home in a year. 2008 - 2009 was bad, but I put more in then, too. The reality is that the "great recession" created the foundation upon which I built a small fortune.
The author's point is that anytime the butterfly effect is used in this way (identifying the singular cause of a chain) it insinuates that we can always pinpoint such a butterfly if we look very hard or that there is one single such butterfly causing the chain of effect in the first place. However Lorenz (at least per the author) tried to make the exact opposite point. Among many many variables if one slightly changes (e.g. flap or no flap of a butterfly's wings somewhere) it can affect a lot, but we don't know which one.

I don't know it's wrong per say to use it as most people do but I see the author'a point. It's often (falsely) used when there is a chain of ovents and we know which thing caused that chain.
> Personally, I had a lovely childhood, and nothing traumatic ever happened to me.

I think that's the point. Lovely != perfect. Not that I'm trying to be pedantic here...but "perfect" says a lot. If you think you had the "perfect" childhood you're essentially claiming that there is no possible way your childhood could have gone better. It's just sort of myopic thinking that there aren't other ways to enjoy life and that might reveal other things, such as a lack of empathy or perhaps masking something else.
Well, in theory a company like these can create robots that are operated from anywhere in the world. In that case, the operator job may be outsourced as it may be cheaper and less of a hassle than to have a person in X country getting paid more, complaining and going on strike.
Minecraft construction is weird. Minecraft's reason for existing is that people think it's fun to make simple things mind-numbingly hard by using the crudest lowest-level building blocks, each block simualting with horridly monstrous gobs of computing powes).

So it's the worst of both worlds -- an expensive simulator for tediously manipulting low-level primitives. Why not manipulate primivitives efficiently, or use high-level constructs?

Then serious Minecraft constructors build mods and tools to automate the tedium back out anyway, so they design whatever nice things using high level tools, but then execute and inspect the builds on inefficient computing systems of cryptocurrency-level of wastefulness.

Why not just make whatever thing you want out of good (virtual
or physical) materials in the first place, and then put it under the microscope/oscilloscop/decompiler/hex-editor to marvel at its complex structure?
Being a vegetarian means eating plants and plant-based foods and dairy. Many vegetarians eat eggs but many others don't. In India, folks that don't eat eggs (but do eat dairy, go figure) call themselves "pure" vegetarians, and the folks that eat eggs are often called "eggiterians". But, in general, pure-vegetarians and eggiterians are considered to be vegetarians.

Thats pretty much it. Additions or subtractions from the above diet results in a different label (vegans, pescatarians, omnivores, buggyterians? etc.).
Most parents do not spend time playing the games their children play (HN is an outlier here). I see parents giving their phones to their children with an active credit card on file. Its not really the parents fault, how could they know?

All the games start as fun and innocent. It's when the child get past level twenty that the difficulty kicks in. You have to pay to make any significant progress. Most kids don't know any better, all they do is press the button to progress. The parents don't know any better, all they did was give the phone to their restless child.

The game developer however, designed it specifically to trick both parent and child.

This issue is that we can draw a causal line back to a single event, e.g. the hack.

Their definition (presumably the original definition) of the butterfly effect requires that it be untraceable. If you make a tiny change to initial conditions, you can’t accurately predict the outcome without a complete model.
The term "exotic" in a chemistry context means one of two things.

First, it can mean observed chemistry that is seen neither in nature nor the lab under ordinary conditions. In other words, it is theoretically possible but the required conditions are so atypical that the expected probability of it occurring unintentionally are very small. I'm guessing this is the case that applies here.

Second, "exotic" can mean engineered chemistry that is far outside the standard industrial spectrum, typically because there is a unique application with very special requirements. Industrial chemistry is all about price performance of the chemistry not absolute performance, but some use cases are more performance sensitive than price sensitive so people will design bespoke and unusual ("exotic") chemistry for the purpose. It is a curve. Everyone uses the cheapest chemistry that still does the job adequately.

I think we're going a little bit crazy with the complaints about the tech interview process lately (I'm not a fan as well). Now it's the shared scratchpad to blame as well?

It's just a shared buffer that works pretty reliably and no interviewer cares about your typos or lack of indentation.
There is an economic component in this. The people who would really want a bicycle had neither time nor money to develop them nor money to afford one. People with time and money would immediately think that horses were more practical. And they wouldn't be wrong.

It wasn't until the mid 1800's that the people who would want a bicycle could afford one if such was available. You had a middle class with disposable income. And simple mechanical contraptions like bicycles were cheaper. Because steel got about 20 times cheaper from 1860 to 1890. And things like chain drives had become industrial commodity items.

I interpreted the OP as implying a strong relationship between the laws of physics and computation. It's trivial to assert that there is a relationship between the laws and physics and computation because there are computers.

But saying that the laws of physics specifically lend themselves to computers involves finding reasons that this may be so.

Yet if there is no inherent computational property in physical nature (like say that the laws actually reflect cellular automata, or are fully deterministic and are not nominal), then we ought to be skeptical that Turing Machines are somehow essential to physics or physical constraints, or that we should be surprised if Turing Machines are common.

Maybe Turing Machines are common just because the definition of a Turing Machine is syntactically weak.

By the way, push bikes (i.e. the hobby horse) are very common among toddler and preschool age children in my circles. I don't see why a wooden version of this couldn't have been common much earlier than 1817. Wood is sufficient for its construction, although I do suppose a metal bearing would be superior.

sadly, because of to much fraud i guess, china now doesn't allow more than one account per person (it's actually per bank, but i suspect only because it's not easy to enforce across multiple banks)

with that restriction in place, 2 or 3 accounts is manageable, but 7 almost impossible.

ideally the bank should allow to split your account into sub-accounts. so that nominally (for tax and monitoring purposes) you still have one account, but for money management purposes you have multiple.
Amazon profit from non AWS biz is in small billions and less, while it may be large in absolute, it is not high as percentage of revenue or by employee. Only way to beat Amazon in profit is have ridiculously high efficiency which is very difficult, or have a different business model which is normally a niche and will not be amazon scale.
A lot of this is why I didn't say it wouldn't affect Jeff at all, or try to predict the particular impact, but just that it would be... strange. Even if you could objectively analyze the full business picture, nobody could fully analyze exactly how Wall Street would react; the ability to do that would imply the ability to get very rich on Wall Street very quickly.

I forget where it was, but I also recently read an article musing on the idea that in the modern era we seem to have a new threat emerging where companies establish very, very firm footholds in some particular industry, and then use that to leverage their way into other industries because they can literally out-resource the entire competitor base of that industry. In some sense, in theory this has been possible for a long time, and we've had things like Samsung which are massive conglomerates, so it's not a new problem in quality, but the quantity of money that can be brought to bear this way in the 21st century may still make this a new sort of problem for trust busters to keep their eyes on.

Ask HN: Best way to relearn basic math?
I'm considering going back to school, but upon further thought, the first major roadblock is that I seem to have forgotten most high school math and probably even some easier stuff! I'm sort of concerned about my ability to relearn 4 years of mathematics in a year or two and was wondering if anyone had and books / tips / etc. to make it easier
Horses can certainly be ridden without stirrups. In fact stirrups weren't invented for over 4000 years after the domestication of the horse. The Roman Empire had no stirrups. The hardest part of riding without stirrups is mounting. It requires some mixture of strength, coordination, and a cooperative animal to mount from the ground without stirrups. Once you're mounted, staying mounted is not much more challenge than staying mounted with stirrups.

Yeah in deep water you either have to have somebody on the other side holding that gunwale down, or you have to pull yourself up on one end. Nobody boards that way from the shore, though. You just have it sitting in the water where it will barely touch bottom if you put all your weight in. Then you get in, and it's sitting on the bottom, balanced. Then you push off with a paddle or stick. The whole process is much easier than using a dock.

Is this correct? SA, or Selective Availability (an intentional degradation of accuracy) was turned off in May of 2000. This allowed existing civilian C/A code GPS receivers to generate better solutions immediately. It did not involve any keys or release of keys.

I do not believe that this is true.

Again, profit margins for this sort of work are tiny. Adding significant wage costs would almost certainly consume a huge percentage of profits at which point the suppliers of capital will invest their money elsewhere.

If you are going to make such a strong claim, you probably need to back it up with data.

Disclosure: I work at Microsoft but not on the VS Code team. I’m a huge fan of VS Code, however.

I’m not going to get into a whole thing about the telemetry in VS Code because I don’t think it will be helpful/productive, but I will point out that anyone who wants to turn telemetry and crash reporting off can do so in the Settings part of VS Code — no need to install a separate app [1]. As that page makes clear, however, individual extensions themselves may have their own telemetry that can be turned on/off in their own settings, assuming the developer has chosen to do that.

The Legal Side of Open Source
I can also comment here. I built and still run a petabyte-scale web crawler:

https://www.datastreamer.io/

Common Crawl and other sources do in fact have a ton of data that can be used which is very affordable.

The DATA itself stopped being a real competitive advantage probably 2008-2010.

Google's major advantage now is its algorithms and the fact that they've proven it works and is reliable.

Most importantly, its the brand. Google MEANS search in the US and that won't change anytime soon.

PS,... if you need tons of web and social data Datastreamer can hook you up too :)
Exactly.

I tried it for a few weeks and couldn’t stand it. There’s just too much non-Mac UI for a tool that honestly isn’t that powerful. For example, the search and replace is truly awful. I use BBEdit because it’s both consistent and powerful (better search and replace than vim).

This is coming from a guy who used a highly customized vim set up as his primary editor for years.

REST Anti Patterns
I haven't tried it, but I would make a somewhat educated guess to say, no. Not that it can't be done, but that it probably isn't as easy to get the reaction going as regular thermite.

Thermite made from aluminum and iron can start with a child's firework sparkler, so it is pretty easy to make and use.

Titanium, while not a noble metal, is more resistant to heat and corrosion than aluminum and is just generally less reactive. You might call it "less un-noble" than aluminum. I expect that you'd have a much harder time getting thermite started using titanium. Just look at how much it took to get the titanium fire going on the Crew Dragon- a chunk of NTO had to slam into a valve at really high speed.

Edit: Since you piqued my curiosity, I decided to see if it had been done before. It has: http://developing-your-web-presence.blogspot.com/2008/10/on-... You replace iron oxide with titanium oxide (since titanium pieces oxidize only on a thin outer layer I expect you would need a very fine mesh), and keep the aluminum. This seems to need a little work but it has been done.
even a keyboardless PC in your pocket would have been hard to comprehend

Given there were two pocket sized PCs released in 1989 - the Poqet PC and Atari Portfolio, that seems unlikely, except in a "the future is here but not evenly distributed" sense. "How would you use one without a keyboard?" "You'd touch the screen directly" "oh, ok".

But even then, LCD pocket calculators were common by 1989. Wearable computing had been around since 1981 (Steve Mann) for anyone following tech developments. Seiko had released a wearable computer watch in 1984.

In 1989 you didn't even have the internet, much less anyone purchasing things online

But you had telephone ordering. And you could have had fax ordering. Back to the Future 2 came out in 1989 and they were predicting a future world of 2015, which included a kind of tablet computer, head mounted displays, flat-screens, implicit voice recognition[3]. OK it's not PCs, smartphones or the internet but it's enough that a blockbuster Hollywood movie expected people to understand "pay by putting your thumb on this portable device", and not find it "hard to comprehend".

(Terminator was from 1984 and that was a mobile, keyboardless computer, in a sense).

Amazon earns a lot of money from quite a few things that have nothing to do with warehouse workers. In particular I have read that half their profits come from AWS. I don't think that is enough data to support your claim.

A better set of numbers to look at might be Walmarts (more of a pure retail company). They make maybe 10B in profit per year (it varies a little) with 2M workers. That's $5,000 per worker which isn't much wiggle room.
