I am aware of the distinction between soundness and validity, but logic has strict types. I am referring to the type of the conclusion being wrong. "Therefore, all humans live on Mars" is not a valid conclusion from those premises if their truth value is not established. One must conclude the entire proposition "Therefore, if all animals live on Mars, then all humans live on Mars" for the argument to be valid.

Our strict types are Fact, Hypothetical, and Implication. It is only valid to use possibly unsound premises if you admit their type as Hypothetical and not Fact. If our argument includes premises of type Hypothetical then it is only valid to make conclusions of type Implication, which have the form "If <Hypotheticals are True> then <Fact>."

Disguising Hypothetical-type premises as Fact-type, and using that to draw conclusions of type Fact instead of type Implication is how people create strawman arguments in bad faith, and can be prevented at the validity-checking phase by enforcing strict typing.

5 Strategies for Efficient Accounts Receivables Management
Very often, companies go out of business because they run out of cash. One of the biggest factors in ensuring a healthy cash-flow is how you manage the account receivables of your business. ‘Accounts Receivables’ (ARs) is the term used to refer to the money your business will receive in exchange of the goods or services provided. They are good indicators of a business’s profitability and income. Therefore, any inefficiency in them can impact your business dramatically.

In my case if I have to do it, I'd rather pay the price the first day, then keep the momentum. Also the third/fourth day there is a payout as you get a nice 'mental high'...

I like the idea and a point-of-sale like system seems like it would make a good product.

A couple years ago a new bar opened up across the street from me. At the same time, a liquor store down the street was going out of business and put most of the liquor on clearance. The new bar owner filled me in on the state of liquor in Massachusetts. Apparently the system is super controlled by distributors. Even if he wanted to go down to the liquor store and buy 100 bottles of liquor on clearance, he couldn't. He can only buy through a licensed distributor. Some of the liquor he stocked was actually more expensive through the distributor than it was from retail liquor stores in the area. The industry has special controls in place, like special caps on dealer-distributed liquor. He joked about buying some of the clearance liquor and pouring it into the bottles. It was pretty clear that I was paying higher prices because of the distributor-controlled market.

Massachusetts seems to have some of the most strict alcohol laws around. Unlike neighboring states like New Hampshire, we can't order wine from wherever we want online. This means that many of the wines that I'd like to drink aren't available to me since no one in the area distributes them. Some people get around this by shipping wine to friends in nearby states or by traveling to places and shipping cases back via UPS marked "tiles + olive oil".
GoMobile: Library development for IOS/Android
I just switched from vim to neovim to evil. I can't see myself ever going back. (Neovim was basically just vim with async support, and terminals, but as a tmux user, that didn't really grab my attention).

There's a lot more polish in the integrations for emacs than vim, likely as a result of literally everything in the editor being a function call that can be hooked into.

The only thing I miss is solid tab functionality (there's a short of hack I've seen so far, but feels too rough for me). But honestly, with projectile + heap, I barely miss that.

Company-mode far outpaces the auto completion options in vim (though to be fair to the plugin authors, apparently they need to resort to major hacks to perform some of the things they do). Just as an example, when you autocomplete a function call, it populates the arguments and let's you tab through completing them. This same functionality sits as open tickets in the major vim autocomplete plugins, with a response of essentially "this is really hard to do in vim, hopefully we can figure something out in neovim".

It's worth the 2-3 days to make the switch and set yourself up. Also, a recommendation -- autostart emacs in server mode and use enacsclient to connect to that for all your editing needs.

Eastern North America is the genetic centre of diversity for the Vitis genus, and the likely ancestral origin of it. So it is somewhat fitting that the Norse explorers named it Vinland and explicitly called it out as something they observed.
You can also make a command that inserts a file into the current tmux buffer, which is technically a much more straightforward solution than reimplementing terminal emulation, I think.

I think the way forward is something like the Distributed Library of Alexandria. The artists distribute their own content for micropayments, p2p networks provide the CDNs. Done properly there's still room for real value-add services in the middle to provide different interfaces and curation.
It works fairly nice with ConEmu and other terminals. The performance is also quite good: I installed clang and built a big-ish C++ project and it compiled faster than using MSVC on Windows directly (10 vs 12 mins, roughly).
Crazy as those UIs look, there's a certain method to the madness. Colors and varying shapes help create spatial memory which helps with data entry.

The person who works with this every day knows intuitively that "pink box, bottom row, second from left" means something specific without having to read the labels.

If this UI were redesigned in the prevalent iOS 7 style with uniform design elements, abundant whitespace, very little contrast and lots of text labels in a light typeface, I think it might actually reduce usability.
> but the graphs I can find show that there is a steep increase in the late 70's, not after the Dietary Guidelines were written in the early 80's.

But still, the upward trend follows the cultural meme that "fat is bad" that started propagating in the early 1970s. The dietary guidelines only formalized that bit of "scientific wisdom".

Hey, thanks for the comment!

I wasn't aware of math-42, thanks for pointing it out. From looking at their websites, they seem to be mainly focused on solving exercises for students while I correct students work (they have a beta training that might do that, but that's not what they are currently focusing on).

> Could you modify your AI to cover math problems which I cannot practice with math-42? Or maybe add features such as formula recognition with your smart phone, etc.

Yes, that's exactly what's on my pipeline. I plan to cover everything in high school, ideally helping the students to prepare for exams at the end of high school.

> They claim to use their own math AI, too. It might be very tough to compete with them without offering additional features.

Honestly, education is a huge space and a competitor is the last of my worries (I am more concerned about getting users first), and they are many apps or website that already that are here to help students in math.
But C on microcomputers did not come any earlier than Pascal or Modula-2 compilers.

My first compiler was Modula-2 on my Atari ST. But it was difficult to do much in it because so much of the OS documentation and example code was geared towards C. Also compiling on a floppy based system (couldn't afford a hard disk) was terrible.
You can't stream it.

> Apple killed the floppy

What'd Apple do to kill the floppy? I remember that floppies really only died after pendrives became common. Even with CDs before, there were still floppies around, since it wasn't as simple to copy data to CD (not to mention lack of removal).
I wonder how much of that is simply due to an explosion of supply driving prices down. It's so much cheaper to record and distribute music that there's no scarcity at all.

What is real food?

I disagree strongly. Eating shouldn't make you tired. I could eat 2 1/3 pound greasy cheeseburgers with toppings but if I skip the buns, I feel like I ate nothing.

There is something legitimate to intermittent fasting, ketogenic diets, avoiding refined carbs, avoiding bread etc.

I have a serious disease that is thought to prevented by ketogenic diets. And I think there's an equal chance I got the disease from refined carbs as anything else.

I also know many so-called experts in this field (MDs) and they know nothing; and worse they do not want to know anything.

My conclusion is simple: just don't eat bread or drink any sugary drinks.

Spotify isn't competing with other industry distribution methods. Distribution is a solved problem: there's no technical reason why anyone can't listen to any recorded music ever whenever they want for near-zero distribution cost, through torrents.

"Only allowing distribution methods that get paid" is the problem. The content industries are now in the business of preventing distribution, which turns into an eternal war on the open internet. The streaming model de-escalates this and provides a way of paying for convenience.
Yes, increasing the clutter. iMac is a failed design that forces me to add mess and clutter in order to get to an appropriate functionality. The computer itself is not extensible and hardly serviceable. The alternative, Mac Pro, is now only for rich people.

UK class is all about manners. And money.

The upper classes are effortlessly sociable, polished, and polite, even if they think you're an idiot - unless you're the help, in which case they aren't.

There are some subtle markers you can only learn either by being born into them or being told about them.

E.g. when middle class are introduced they say "Pleased to meet you."

When upper class people meet they say "How d'you do?" - and if someone says "Pleased to meet you, they immediately know they're not dealing with one of their own."

I spent some time on the edges of the upper class scene, and the polish often hides drama and resentment - possibly because public school in the UK can sometimes seem to be a bizarre form of institutionalised child abuse.

It's hard to imagine someone who's set to inherit a gigantic country mansion feeling that life has given them a raw deal, but I've seen it happen.

There's also an almost complete absence of passionate creativity. I've seen working class kids (almost literally) kill to become musicians or artists. The upper classes sometimes drift into it, but the work is often derivative and shallow, and doesn't have the kick it has when someone has had to struggle.
fucking german are the worst. But seriously, reading this made my stomach burping. Even without hating on Microsoft monopoly in Software never was a good thing.
It's not node.js that's horrible: it's great for what it does (web development). When taken out of that use case, it's awful, because it's simply not meant to do systems programming or to make local applications.

It's kind of like people who knock Perl: it's made specifically for text parsing, nothing more, and too many people use it for much more. Since it's not meant for more complex things, it fails, understandably.

I think what the comment was trying to point out is that oftentimes there are things on Hacker News that are written in JS that shouldn't be: systems programs, emulators, shells, etc. This is not the fault of the ecosystem itself, but rather the misunderstanding of the authors about the viable use cases of the tool that they're using (node.js).
It would be awesome to see a list of the winning companies and the approximate multiple on invested capital returned for each of them, along with which companies fizzled out.

Not expecting to ever see that, but it would be interesting to learn which ones they thought would be huge successes and what the eventuality was.
Not entirely true. You can't use a DVD for a public showing, for example.
I mean the type of the conclusion is wrong. If our argument includes premises of type Hypothetical then we may only make conclusions of type Implication, of the form "If <Hypotheticals are True> then <Fact>."

Arguably the film business is already dying, and all it has left to offer the mass market is bigger and bigger cinema spectacle in increasingly stupid superhero movies.

A lot of talent and longer, more complex storytelling is moving to TV, which is itself moving to Netflix.
Now, obviously I’m not suggesting you should go clutter up your design work, or make it look crappy on purpose. I’m also not suggesting that the examples above couldn’t be improved.

My point is: there is no single right way to do things. There’s no reason to assume that having a lot of links or text on a page, or a dense UI, or a sparse aesthetic is fundamentally bad — those might be fine choices for the problem at hand. Especially if it’s a big, hairy problem.

> Avoiding the stencil buffer (why?)

GPUs and all drivers do not support independent stencil buffer. If you need a stencil buffer, then you need to make a Depth=24, Stencil=8 buffer, also called D24S8.

If you have floating-point 32 bit depth format, sorry, no stencil buffers.
If you don’t have depth at all, stencil buffer would take 4 times more VRAM: for color buffer, having just single component is fine, e.g. GL_R8UI or DXGI_FORMAT_R8_UINT.

We are getting back to that now slowly, but with Web interfaces on screens with 9x the area and a quarter of the information on each page.
Yeah. The main thing people probably want is "TeX quality" typesetting of mathematical formulas inside web pages. Bundling the entirety of TeX inside a browser for this purpose would be kind of a hack, and suboptimal in many ways. I think that instead of just using TeX as a black box, it would be more interesting to actually learn what makes its formulas look good, and apply these lessons in modern software.

There's a related article called A Functional Description of TeX's Formula Layout [1] that describes a more modern reimplementation of a part of TeX.
