This is very inaccurate because the trades execute immediately. Very rarely are you able to actually execute a trade immediately.

That's true even in the stock market. Stock market simulators need to build in a slight delay to be accurate.

More often in bitcoin you are putting in speculative buy and sell orders at a fixed price and they execute as soon as someone is willing to sell/buy at that price. It could trigger in minutes or weeks (or never) depending on how the market moves.

Also, I'm not sure if the prices here are agregate accross multiple exchanges but in reality the book of orders needs to be deep enough in your exchange to actually execute the order.

If the deal is in another exchange you would have to transfer your coin to take advantage of it and at current network speeds by the time the coin gets there your deal will be gone.
Because it's a lie. A lot of natural gas plants came online in 2017, which makes it a lie.
Generally speaking, what determines the "clock speed" for FPGAs is a combination of the design of the FPGA device plus the complexity of the design being implemented on it.

Let's imagine you design a CPU on an FPGA. One way to measure the speed of that design is to look at the speed of the slowest operation of that CPU. The clock needs to be set at the speed at which the slowest (most complex) operation can reliably run at.
What's interesting is that various types of users find themselves with different problems using the App Bundle way of distributing applications.

For Windows users switching to Mac OS X, it's not really something they're used to doing. Instead of downloading an installer, clicking "Open" in the browser, and just following a guide leads to less issues with placing the application the correct place (Program Files), instead you get either a Zip file (so the bundle is in Downloads), an actual Installer (typically a .pkg), or a Disk Image which is often never unmounted. (I once saw a family member with 7 Flash Update disk images mounted)

As such, a lot of OS X users find themselves with a the Skype app in Desktop (inside a Disk Image), their Mail on the dock and some other app in Documents or Downloads. It requires that you organise it yourself.
How does one go figuring out income levels? India has such a poor tax base just 2%[1] of people pay taxes.

> If nearly 300m Indians count as “middle class”, as HSBC has proclaimed, some of them make around $3 a day.

Then, I would be curious to know how one accurately is someone "measuring" what a middle class is since only 2% of the population sample is available.

No money going towards nuclear....

If people were serious about ACTUALLY reducing carbon emissions, then baseload power production would be nuclear.

Please look at France as an example.

France: 5.0 metric tons per capita (2013)

US: 16.4 metric tons per capita (2013)

https://en.wikipedia.org/wiki/List_of_countries_by_carbon_di...

Nuclear power is the largest source of electricity in the country, with a generation of 416.8 TWh, or 76.3%[2] of the country's total production of 546 TWh, the highest percentage in the world.

True -- if the service stays up. In practice, I've lost more data from online services shutting down than I ever did from old disks in my possession. Gmail and Facebook are probably going to be around forever, but the rest, who knows. The web itself isn't even 30 years old yet, so I don't feel confident predicting my data is going to survive there another 30.

When a disk format is obsolete, I can throw the disk in a shoebox and come back a couple decades later. When a web service shuts down, I have months/weeks/days (or maybe no chance at all) to get my data out, and then it's destroyed.
Most modern FPGAs have a PLL (or DLL) implementation [0] which can multiply the external clock by some rational number. e.g. 50MHz external crystal clock is multiplied by 5/2 to obtain a 125MHz internal clock.

I suspect early humans would have been able to make marks on trees to record routes or food caches for millennia before coming up with the more abstract idea of an alphabet. This would have been good enough for this task. The earliest cave paintings known are something like 40,000 years old; surely anyone capable of that could come up with a food marking strategy.
Ah! Makes sense doesn't it!

However the trick is in accounting for trading costs and dealing with order execution, particularly if you are reliant on maker fees only to remain profitable.
One interesting side effect of large chains cooking cheap, addictive, shitty food is that they have cornered that market. At least near me, all of the small restaurants make excellent food. They appear to know that they can't compete on price so they compete on quality.

I know a little bit of how it works...

Interesting part is in tdraw() which draws one triangle.
First find the bounding box of triangle from view space.
Iterate over pixels in that box.
Map pixel into barycentric coordinates of triangle. (distance from vertexes.)
Check zbuffer to see if visible.
Take dot product of light direction and triangle normal to get shading.
Use barycentric coordinates to interpolate where in texture map to sample shade.
Blend shading and lighting.
Update zbuffer and pixel color.

A model is made of lots of triangles. Each triangle has vertices with additional attributes that map into the texture map.
I’m a big fan of Monero, ARK, and RaiBlocks. The latter allows for fast transactions (around 10s on average in my experience) by making each account responsible for managing their own blockchain (thus there’s no “mining” and crazy energy consumption) and it’s all connected over the network via a DAG data structure.

https://en.wikipedia.org/wiki/Salt_lake lists a number of salt lakes.

One is https://en.wikipedia.org/wiki/Mono_Lake , which did not begin with ocean water.

Another one is https://en.wikipedia.org/wiki/Don_Juan_Pond , which is a shallow Antarctic hypersaline lake that almost never freezes.

https://en.wikipedia.org/wiki/Little_Manitou_Lake_(Saskatche... is a terminal lake which formed after the Ice Age.

I'll also add a non-endorheic salt lake, https://en.wikipedia.org/wiki/Great_Salt_Plains_State_Park , made salty from the dried salts from an ancient inland sea. (I think it's the Western Interior Seaway, but I could be wrong.) In any case, it began with ocean water, which dried up, and that salt is dissolving again.

> [Kotlin] does not overlay Java like e.g. Groovy does

Apache Groovy 1.x was dynamically typed only, and focused on scripting and glue code for the JVM and syntactic compat with java, so could be said to "overlay Java". Since Groovy 2.0 however, it changed tack with static typing targeted for Android development, not keeping up with syntax changes in Java such as lambdas from Java 8, and tried to compete with Java instead of complementing it. It no longer "overlays Java", and in fact lost out to Kotlin and Scala in its effort to compete with Java. Groovy should have stuck to its knitting instead of changing direction every few years.

VS Code will automatically pull type definitions from npmjs.org, so you get code highlighting and inline errors for free (not sure how much such automation is included in VS2017).

Many npm modules come with their own typings. Those which don't usually have them in the definitelytyped repo. For those 'npm install <foo> @types/<foo>' should be enough so that typescript can find both the code and corresponding type definitions.

The rest of your setup seems to be related how you build and bundle the files. I use webpack and a typescript loader, and there is literally nothing more that I have to do after installing the packages, I can just import (or require) them in my code.

I've seen the argument that you offer someone enough on exit so that

* the leaving person doesn't raise a stink that hurts morale,

* you signal the labor market that it's worth taking a risk on your startup (low pain if things don't work out),

* you signal other employees and managers that decisiveness is a core value,

* the opportunity cost of misapplied talent is so large that you'll pay a bounty for people to "fire" themselves from a role or their job and make room for a better-fitting person.
The Tandy 2000 used an 80186; I still have mine in the attic. It ran MSDOS 2.11, but it was not BIOS-compatible with the IBM PC (which explains why it was a market failure, even though it was technically superior in many ways). For example, you could mod it to have 896KB of base RAM (compared to the usual 640KB) - I had this done to mine. You could do this because video memory was mapped to a different location than with IBM PC's (but consequently, programs that wrote directly to video memory for speed wouldn't run unaltered on the 2000). I got tired of dealing with the incompatibilities and got a 286 from CompuAdd a couple of years later.
OpenEBS is a containerized block storage
Not sure if this is recent enough, but I moved my self-hosted email to a new address a little over 4 years ago.

The only systems that have had even tiny problems with were Gmail and Microsoft. With Gmail it took a while to build reputation as a non-offender. With Microsoft the first time I sent mail to their way, I got an automated bounce with instructions to forward to a certain address for human verification. That check round took maybe 12 hours and I haven't had any problems since.

I find that pretty reasonable.
There are billions upon billions of dollars spent on nuclear, it just doesn't produce any new capacity.

Look at the failure of VC Summer, and what seems to be the imminent failure of Vogtle.

Since no private company is willing to take on the financial risk of building nuclear power, the federal government provides massive loan guarantees. For the "nuclear renaissance" to take place, state governments passed special laws so that the utility's rate payers took on all the risk of the failed builds. And the failed VC Summer build in South Carolina accounts for double digit percentages of current electricity bills for the utility's customers.

If somebody can figure out how to do project management, engineering, and the logistics of construction, there are lots of communities eager to welcome nuclear. But the industry has failed to deliver capacity even when given every opportunity to build.

I get your frustration with architecture of architecture. However this kind of AOA has been going on for a long time in a similar domain of control theory.

Model Predictive Control is a method of applying a model of a process to estimate it's state. Per Wikipedia, it's been used since the 80s. When you apply it to tracking something you aren't in control of, say an enemy plane, you need to use multiple models, and then pick the most probable solution.

It's not elegant, but it's not actually a bad way to get good results.
There's a bug: when I "invested" $1k and sold it at a +0.21% profit, I made $210 instead of $2.10 (basically, they forgot to divide 0.21% by 100 to get a multiplier; if only real-life was this easy haha) :D

Perhaps, but like the grandparent post said, one can find other online stores that don't require JavaScript.

Going beyond what the grandparent post said, JS is a big reason why websites are slow, insecure (from the user's perspective), and time-consuming. Amazon.com's site is ridiculously sluggish precisely because of needless JS. There's nothing about purchasing something online that legitimately needs JS to make that purchase work. You can search for stuff on Amazon without JS but (for all I know) purchasing doesn't work without JS because of implementation choices Amazon made. I'm not so convinced Amazon's prices are all that great, and buying locally is often a better deal for things I buy. The more I learn about how Amazon conducts business (see https://stallman.org/amazon.html for many reasons why) the more interested I am in avoiding them.

If you want to buy new or used books and you want to do business with Amazon, AbeBooks is owned by Amazon and AbeBooks works fully without JS.

I read this article with interest. 70MillionJobs is a for-profit recruitment platform for people with criminal records. Our goal is to match the huge pool of untapped talent (those with records) with employers that have urgent HR needs.
In this capacity, my team and I engage with large, national employers, so I think we have a strong sense of where the corporate zeitgeist lies regarding hiring the formerly incarcerated.

While the Times author points to a historically low rate of unemployment and cites business conditions in Dane County, WI, this willingness to hire men and women with records does not generally exist with large, national employers. Nearly all of them have internal criteria relating to who they will or will not hire, based upon the nature of the crime(s) an applicant has committed and when it occurred. Most require at least five or six years to pass before they'd consider hiring someone guilty of a felony.

And therein lies the rub: there's nearly an 80% chance that someone released from jail or prison will be re-arrested within five years of their release. The vast majority of them will be unemployed at time of re-arrest. Contrariwise, there's very little chance of someone who has found employment being re-arrested. Employment is truly the silver bullet that short circuits this pernicious cycle of recidivism.

Recent studies have shown that those with records often emerge as an employer's best hires. Unlike others, people with records have no sense of entitlement and truly appreciate the opportunity they've been afforded. Typically, they reward employers with great loyalty, which translates to much greater retention (the true bane of HR professionals).

While attitudes are changing for the better (I, as a formerly incarcerated person, have noticed this in my own life), there still exists a great negative bias towards those with records, the NY Times notwithstanding. Racism figures mightily in this equation. But we're a country that elected a racist President, whose Atty General is eager to reinstate ineffective drug laws (including marijuana) that destroyed lives, families and communities in the 80's 90's and even today.

Anyone with a record can attest to the stigma that doesn't leave after doing one's time. In fact, for most, it's a life sentence, a sentence that even low unemployment can't expunge.

Hack Club: A worldwide network of high school coding clubs
No. The problem described is that the unstable code is being pulled upstream. Merging into the root branch is equivalent to merging into Linus’s repo. Nothing prevents a Windows developer from checking unstable code into a feature branch without merging up, just as nothing prevents a Linux developer from checking unstable code into a private clone without Linus pulling it in. The difference here is simply whether the feature branch has a central host. Decentralization doesn’t fix this issue. Proper code health practices do.
No, it's a symptom of capital concentration. Big cities are growing economically because that's where the money is, thus that's where the startup and VC money goes. The rest of the country isn't seen by investors as the best place for growth, so remains relatively underdeveloped.
