[0] Aircraft grade aluminum alloy's composition roughly includes 5.6–6.1% zinc, 2.1–2.5% magnesium, 1.2–1.6% copper, and less than a half percent of silicon, iron, manganese, titanium, chromium, and other metals.

[1] Aluminum cans are typically 1% magnesium, 1% manganese, 0.4% iron, 0.2% silicon, and 0.15% copper.

There are a lot of metrics that determine the appropriate use of various grades of aircraft level alloys [2]. I guess from the outside some big considerations are how the metal reacts to temperature change and how well a metal cylinder can handle stress while staying light.

RISC instructions are all the same size in bits to achieve fast decode speeds. Thus you must choose between 32bit instructions or 16bit instructions. ARM supports both, including function calls from one to the other.
For those who don't know, Silicon Valley Bank provides merchant banking services for a pretty big fraction of Bay Area start-ups. They have a reputation for "getting it," in terms of being able to support venture-backed pre-revenue companies. This does make the giant paper statement even more ironic.

I'm only focusing on UX. Sometimes that's UI. Sometimes that's APIs. Sometimes that's shell commands. UX covers a wide range of items from casual users to hardcore software developers.

The best UX typically wins. If the implementation is complex or not is immaterial.
But like file permissions, just querying the filesystem (or drivers liceense database) the result is potentially invalid by the time you actually get it. You ultimately have to actually use the filepath or drivers license and let any failure be the truth.
From what I know, the Groovy runtime was a constant-time bottle neck for all builds (time to initialise, interpret etc.), hence the perceived "slow builds" for any small to medium sized project.

I dunno, I think it's an exponential process whereby each year you 'consolidate down' your total current knowledge by X% to make room for new data. You keep the broad strokes of the least recently used knowledge but lose the fine details.

One example I've observed of this consolidation process is that I'm way more prone to accidentally using homophones of a word than I used to be. I know the difference if I'm focusing on it, but if I'm typing I'll accidentally use eg. 'there' instead of 'they're'. When I was 16 I never, ever made this kind of mix-up.

CKAN, the package manager for Kerbal Space Program mods, works by having a central metadata repo that they accept pull requests against for adding metadata for new mods, and then the mods themselves are hosted on Github or SpaceDock or wherever.

It's not quite as automated as publishing a NPM or Composer package, but it's close and works well.

Probably the biggest thing I've learned through hard experience is that great ideas by themselves have very little value. At this point it's irrelevant whether he copied the idea from his client(s), or from Friendster or MySpace. Out of pure luck, Zuck's version appealed to the masses enough to get them to register for the site and use the contact importer. After that, skill took over - Zuck knew that if a high enough percentage of users allowed the site to spam their contacts, growth to billions of users was a mathematical certainty.

This is instructive for many startups. You don't need amazing or even original ideas. You do need to have growth features in place that, if users choose to use them, will make world domination an inevitable conclusion. Then it's just a matter of optimizing until a high enough percentage of users use that feature. If you are successful at this, you will have perpetual growth.

You underestimate gamers as a market. Valve's built a thriving business on virtual hats. Twitch sells access to premium emotes and a wider range of username colors as a subscription upgrade. "Cosmetic purchases" are huge.

Discord could also do what Twitch does and let streamers offer recurring donation options to their fanbases, in exchange for perks like being able to talk during restricted times (eg. during large streams) and custom community-specific stickers.

Could you be more specific as to how pesticides have been criminally negligent to bees? This specific article is about neonicotinoids, which were introduced to replace pesticides with far worse impacts on the environment. Is there a source you can find that shows neonicotinoids as used in the wild being calamitous for bees?

I can find sources for you with commercial beekeepers pollinating canola crops seed-treated with neonicotinoids seeing no change in their colony survival at all.

FB is vulnerable unless it keeps its users very happy. Currently it has a monopoly on a product that's actually quite mediocre and frustrating in many ways, and not seen as particularly cool.

But I agree with your point, the challenge offered by schools is too low.
I work at a small manufacturing facility, while living in a relatively low COL area. The pay is not exceptional, but enough to clear all expenses, have some fun and save 15%. I am given the choice almost every week (crunch periods and other workers plans sometimes take priority) of working either 4 ~10 hour shifts or 5 ~8's. I find it extremely useful and pleasant, and would gladly keep my current job (6:30-2:30|4:30) over one that paid $4-5 more per hour that had a fixed 9-5 M-F schedule.

Having an optional 3 day weekend allows a lot of possibility for longer recreational trips, large projects, dedicating one day to errands and totally freeing the other two, etc. On the other side of the equation, having a wide open afternoon + evening every weekday is great too.

It may seem like I'm just preaching to the choir on this one, but I'm also trying to simply raise awareness of what an excellent benefit it is. Realistically, could businesses in other fields adopt this? It's a great way to keep employees happy (saving turnover expenses) and doesn't alter their paycheck.

[edit]
Since you are working less in exchange for the 20% cut, I realize not every business can do this since paying more people for fewer hours has diminishing returns. Giving the option of 4 10's or 5 8's, though, is still the same hours + work done. Why do we not see this offered more?

Dropbox sells communication and peace of mind, which they believe to be worth $10. The amount of storage synced isn't really the product. Think about it like this: what if, rather than promising 1TB, Dropbox promised to sync "all your files"? Would you find that a more attractive offer?
Cost of one box of ridiculous statement per month: $41

Break it down that way, and it's easy to see how it's not a priority. Likewise, in the article they talk about a 30-min download. So what if a snowflake customer has a slow download - fixing that is much more expensive, and as it currently stands, things are working.
I started writing a reply along the lines of "you may be misinterpreting the authors", but looking more closely I agree that their logic is particularly flimsy here. They explain their reasoning more fully in a 2015 piece, where they concluded that two code bases were distinct because they used different constants:

Searching for "0x61C88647 0xB7E15163" on Google results in barely two pages of results, indicating this combination of constants is relatively rare. Most of the hits are on Chinese forums. Searching for the 2-inverse constant "0x9E3779B9 0xB7E15163" results in a whopping 2500 hits. ... This suggests that the EQUATION group and the Regin group are two different entities.

https://securelist.com/files/2015/02/Equation_group_question..., page 28.

They seem to be totally ignoring the fact that Google is more likely to index text files than binary executables and short lived assembly temp files. If you search on Google, you do indeed find source files with the "0x9E3779B9 0xB7E15163" pair, which makes sense as these are used in the reference implementation: https://tools.ietf.org/html/rfc2040.

But as you say, if you compile the reference implementation, you are likely to produce an executable which contains the negated form. If you then "decompile" this executable, you get the "rare" pair, where "rare" just means that Google is more likely to index the input source code than compiler generated assembly or the output of 'objdump'.

I think you nailed it --- all the compilers are in cahoots, and the perpetrators can assumed to be using one! But not Clang, which gamely tries to vectorize. What's less clear is whether the authors of the exposé are charlatans or just "logically challenged". Since they are obviously smart enough to be working for the "goto source" for commentary on these issues, I'd be inclined to guess "charlatan".
> The reason this is a more complicated situation is that an ordering of vectors in RkRk does not exist... how would one order the vectors u = (1,2,3), v = (2,1,3), w = (3,2,1)?

It seems straightforward to order those vectors by first comparing the first component, then the second, then the third. The result is u,v,w. It's as if you wanted to sort a multi-column report in Excel. What am I missing?

To fend off the hysterics which the word 'design' might cause, I'd maybe phrase this as "evolution hasn't optimised us to last longer than ~80-90 years."

I agree that, in keeping with all efficient system structures, we seem to be built so that all of our systems fall in a heap at roughly the same time.
First off, I am very hesitant to say anything about biconvex problems - I only see them in passing and they are definitely not in my wheelhouse. If anyone out there is an expert, or even just has a solid (basic) reference on biconvex problems, please feel free to drop some knowledge on me.

For this particular problem, which has only one input variable, yes the answer can be resolved with a good-old fashioned Plug-In-The-Answer strategy. For problems with more than one input variable, that will almost certainly not be the case.

Really, all I was trying to say there at the end is that converting the multicriteria problem to a constraint based problem has potential benefits over scalarization. Speaking only for myself, I always default to treating multicriteria problems in some sort of norm-scalarized sense: minimize ||g|| for some vector norm. I thought it was valuable to remind myself, and maybe others, that there are other ways to naturally rephrase multicriteria problems as scalar optimization problems. I'm definitely not saying anything about how easy it is to solve, as in general these constrained problems are going to be harder than the non-constrained linear (or norm) scalarization.
This looks awesome & fills a gap in the market. As a doctoral student I've wanted one of these for years for reading papers. I only wish it were roughly half as expensive.

3/5 of the main points listed in the conclusion of the study centered around directives, summed up in one of the points:
"although the creation of custom directives is one of the most appreciated characteristics of ANGULARJS, the API that supports this feature is perceived as complex to use and understand by developers"

I just started using AngularJS 1.5 at my new job, coming from react, I actually started a list of problems I encountered. Basically everything stemmed from how complicated it get's working with directives and properly scoping/binding where you want.

I don't know if Angular 2 will face these same issues, they still have directives, but I don't know if they're exactly the same. I "heard" that Angular 2 was supposed to jump on the unidirection binding bandwagon. This stackoverflow Q&A seem to indicate it's still two way binding. http://stackoverflow.com/questions/35469024/how-does-angular...

It's more a question of how you mention it. The difference can have a big impact on the conversation. For example, snarky or cynical one liners produce more of the same, and so do thoughtful reflections. We're hoping for thoughtful reflections here.
You could use a Bayesian model to incorporate prior information about the distribution of global medal rates into a conclusion (a posterior) about a particular country. This explanation will be simple and empirical, but ideally you'd integrate over all country-level data and the prior at once.

Count data is nice to model with a Poisson distribution, and a conjugate Gamma prior distribution. We'll assume a lot of things about the distribution of medal rates and medals which probably aren't true in reality.

For the global prior, eyeballing the medals-per-capita list for all countries, it has mean value around 3E-7 and standard deviation about 5E-7. That corresponds very roughly to the distribution Gamma(0.25, 1E6) for the prior. A Gamma with parameters (a, b) has mean value a/b and standard deviation sqrt(a)/b, so I just matched the numbers.

For a country with N medals and P population, we want to update our posterior distribution of their medal-per-capita rate based on a Gamma(0.25, 1E6) prior and a Poisson distribution. The updated posterior distribution is conveniently, Gamma(0.25+N, 1E6+P). (That's the conjugacy property).

So Grenada's medal rate, with N=1, P=100,000, has posterior distribution Gamma(1.25, 1.1E6). This has mean value 1.25/1.1E6 = 1.1E-6. Compare that mean value to the raw medal-per-capita rate of 1E-5 - in other words, if this model is to be believed, we should heavily discount Grenada's great performance. On the other hand Australia's medal rate barely changes from 9.2E-7 to 9.7E-7 by using the prior, close to Grenada's Bayesian rate. So it takes a larger population into account quite naturally.
