"The History of Magnesium"

https://sci-hub.tw/10.1111/j.1559-3584.1957.tb04052.x

Industrial-scale production began in Germany in 1886. There was another significant change in 1924-1925 with the development of a truly anhydrous chloride melt, which significantly reduced anode wear and increased energy efficiency.

For the production of ductile iron, one major challenge was managing the loss of magnesium by boiling since the BP of Mg is so much lower than the MP of cast iron.

"Fundamentals of Magnesium Addition to Ductile Iron"

https://sci-hub.tw/10.4271/640802

You can see multiple gating factors for why magnesium based production of ductile iron was not discovered (or at least industrialized) earlier:

- Early industrial magnesium production was expensive due to high electrolytic anode wear from impure raw materials.

- Electrolytic magnesium production was also expensive due to the high cost of electric power; 1880s-era generators had low thermal efficiency and generated electricity at high costs [1].

- Early ductile iron production suffered from high losses of costly magnesium, due to boil-off. The various economizing measures described in the second paper I linked above did not yet have their own enabling technologies available in the 19th century.

[1] I'm not going to try to reproduce my full work here, but I was surprised at the high cost of electricity I found referenced in an American chemical engineering textbook from 1940. On further investigation of the consumer price index and published historical electricity prices, I found that electricity was (by contemporary American standards) quite expensive before WW II, and relatively expensive through the 1950s. It wasn't until the 1960s that electricity became fairly cheap.

What is BitMEX - and why do we exist?

BitMEX is a derivatives trading platform that offers investors opportunities using only Bitcoin. We are not a spot exchange where you can buy Bitcoin with USD or other fiat currencies.
Across the globe, and particularly in Asia, we have over half a million open accounts, of which approximately 100,000 belong to active users.
Effectively, BitMEX offers commercial hedgers, Bitcoin miners, and professional and retail traders the ability to speculate on the price of Bitcoin, and to exchange Bitcoin risk, with other market participants on a level playing field.
Our platform was developed by ex-bankers who were (and are) well-versed in computer science, financial engineering, and traditional finance. BitMEX launched in 2014 and subsequently has grown to become one of the most important marketplaces in the crypto space.

Our hottest positions are listed below. Please apply if you are interested in learning more. For questions, reach out to people@bitmex.com

Before you advocate 'surveillance testing', you should provide a link to hard data showing what the false-positive rate is.

Not assurances of how accurate it might be...

I want a definitive false-positive rate.

Until we have that, surveillance testing may be more harmful than beneficial.

Is there any evidence Obama campaign made people install apps in the pretext of a poll and harvested FB data?

Don't confuse using "FB advertising platform" with "stealing FB data outside of their terms and selling it"

If CA was not involved and Trump campaign merely used FB advertising, we wouldn't be arguing about this particular point. Still bad on FB, but that is a different matter.

SEEKING WORK — Remote okay

I’m Vijay, full-stack designer and developer from South India, freelancing at https://dffrnt.com.

Designed the award-winning branding for io.js, which eventually merged back into Node.js from which it was initially forked from — https://behance.net/gallery/23269525/IOJS-logo-concept

Previously at Infinera, I did data visualization/front-end engineering using a combination of d3.js and angular.js to bring their Java-based NMS (Network Management System) to the web. Highlights were building a semantic zoom for network topology navigation, icon design and building a visual library of web components that also served as a style guide called INDIGO (Infinera Design and Interface Guidelines and Objectives)

If you need to setup Nginx servers (with caching and TLS), build node.js apps, scrape websites (puppeteer), pull out data from OAuth gated APIs (passport.js/request), visualize data (d3.js), build out a complete marketing packet (logo design + branding, landing pages and full-on websites or web apps using vanilla JS + Node + Mongo/SQL stack), then please email me at vijay@dffrnt.com.

Thank you.
Yes, this. Tooling.

If you want to get started, Clojurists will insist you learn emacs. After all it's so great you must learn it.

Now I have nothing against emacs.

But I don't expect to have to invest significant effort to learn a specific editor in order to use a programming language. No other programming language has this requirement.

I was surprised at how many Clojure users took this as an attack upon emacs. It took some careful explaining to make the point that I have better things to invest my time into, such as building more code in Clojure, rather than learning yet another tool, that does something for which I have other tools already.

There were some great IDEs for Clojure. But they have all fallen into disrepair and being unmaintained.

I'm a Software Engineer with 10+ years of experience (the past 4 100% remote). I have a strong ecommerce and logistics background.
When I refer to a project starting yesterday, in case it was too difficult to understand, I was implicitly asking you for non-posthoc justifications for choosing Kotlin _in 2014_ to build a UI framework that

- should target multiple mobile and desktop platforms (and not, like you seem to think, Android first or alone)

- is a game engine style, Skia-backed project, which you are essentially trying to pick a scripting language for.

So, do you actually have anything to back up Dart's runtime being a worse investment than your proposed ideas (which seem to be "go the way of Multi-OS Engine, that notoriously successful project" and/or "wait half a decade more for AOT compilation that would still be in beta and in a worse state than what we already have")?

Thinking of these metaphors as independent attempts at explaining nature is missing what was valuable about them. Their value isn't measured by how successful they were at an explanation, they were successful in orienting our thinking towards using lower level mechanism to explain higher level phenomena. But this effort isn't undermined as our understanding of mechanism becomes more sophisticated.
The problem was they broke Facebook's TOS.

... and Facebook thinks that's a problem because it's using Facebook to compete with Facebook, not for other moral reasons. They were breaking the part of the TOS where app developers were banned from trying to reconstitute the social network dataset outside of Facebook via secondary signal.
I do agree that Obama's campaign used this much "more ethically" but I didn't then and still don't approve of micotargeting or campaign advertising in general. I really want to see the US get to publicly funded elections because full public funding would cost not even a sliver of what elections current run and provide a more even playing field for candidates.
Correct, even if you look at the URL on each link it will have IDs and tracking code embedded to be able to see who clicked what link and very rarely go straight to the actual URL it is referring to without a hop or two.

> Microtargeting and related campaigns can be distinguished entirely by the content of they present.

So, campaigns I agree with getting their message out is great, but campaigns I disagree with can’t use these technologies.
> For your own sanity, I recommend not thinking about this often...

If you mean this to say you shouldn't check for errors, I disagree. Write errors that fail with an error code are much more common than those that do not. The latter in my experience is usually a particularly bad hardware problem.

For the most common write errors (including disk full, but also errors arising from hardware failures), I think you should make a best effort to check and flag it.

The larger your base of installed machines, the more you will be thankful for this logging. You don't want to be diagnosing rare failures blindly. A low failure rate multiplied by a large install base leads to that problem daily.

> Just like you don't have to do anything intelligent when malloc() fails

This is also false in my experience. I have seen stuff in the field where malloc(40) [yes, that small] fails, and I am still able to log where that happens, write it to disk, and have it be recovered and read by me, the developer. I've also seen malloc fail and a UI program survive long enough to report the error to the user and maybe even retry the operation successfully.

The reason for this has to do with how you react. In the first case: a log file write does not ordinarily result in memory allocation. [fprintf does, but there are other ways to log]. In the second case, firstly, mallocs that fail are often absurdly large, where a smaller malloc will succeed; and second, you will react to the malloc failure by unwinding your stack and this will have the side effect of many stack frames calling free(), which might give you enough space to keep going successfully.
> You should be saying that the phone is a remote control.

> That is both what's actually going on, and a paradigm everyone understands. And it's a stupid short and simple phrase to say. They've ingested it before they even got a chance to subconsciously go into "I don't want to try to figure this out." mode.

I just finished saying that this strategy did not work for me for nearly a year, but please, tell me more.

Explaining it as a remote control is way more confusing because it doesn't behave like any remote control you've ever seen. Every other remote control (short of niche techie phone apps or expensive Logitech remotes that these users have never seen before) is a system where they press buttons to navigate menus or change things directly on the TV. This system requires them to select something on their phone instead, which is very confusing with the remote analogy.

> I would also say while giving that explaination something like "It's not you. Google intentionally makes this confusing because they want you to think you are casting or projecting something for who knows what marketing reasons."

I don't think it's marketing reasons. I think that unless you're super technical, it's just flat out an easier metaphor for people to understand.

Hell, even with an understanding of what's actually going on, I still don't think it's inaccurate. The lie is just that you're taking the source URL and credentials and casting them to the TV, rather than casting the content itself. But you are definitely moving state from one device to the other, and that's the metaphor the device is built around.
This is a very interesting model to monetize open source and it's not limited to that. It could be used for ebooks, courses, videos, art... anything, really.

The fact that they open it up to everyone once the desired sponsorship goal is reached is a nice touch provided it doesn't make sponsors who paid feel shortchanged.

One way to prevent that is by acknowledging sponsors upon release. The other way, somewhat naturally occurring in most cases, is the delay required to achieve the target number of sponsors.

Generally, I like it.

The truth is, that person is not a normal employee, it's the first hire in a very early stage business. If you treat that hire as a regular employee, you will build expectations and won't be able to live up to it, and it will backfire for both of you 6-8 months down the road.

If that's true, then I hope that person gets compensation that is consistent with that status. I wouldn't have a problem with that... what gets me is when people want somebody to basically act like a founder in terms of commitment, but the compensation is just "regular employee". F that.

Jack Dorsey is looking years ahead into the future. He wants to bring a better remote work ethos into Twitter and reduce the reliance on a San Francisco-based workforce. He wants to explore emerging opportunities around the globe, specifically in Africa.

Meanwhile, Wall Street bozos and rich Trump-supporting goons want to oust him. I'm seeing all kind of comments on Twitter from white bros mocking Dorsey for wanting to move to Africa.

Frankly, this smacks of racism to me. How dare the CEO of THE TOP TWO "real-time news & discussion" and "democratic payments" tech companies in the world spend time in Africa instead of the USA. The real question people should be asking is, why the hell WOULDN'T he?

When I went through my university's C programming course, the instructor barely knew C. For the students with limited Linux experience, the concept of man pages was unknown to them, let alone that there are man pages for C functions. So no, people don't read man pages because they don't know they exist.
Could it be the case that the least symptomatic variants of the virus will be the winning ones in the long run? I suspect that variants that do the most damage will be the ones quarantined and the ones that do least amount of harm (least symptoms) will spread faster.

If so, will this virus just domesticate itself (or rather domesticated by humans filtering out those more deadly versions)? By domesticate I mean that it lives with us just like the common cold without causing a 10% dip in the stock market.
