Bus routing is just a variant of the vehicle routing problem (VRP), which itself is a generalization of traveling salesman problem (TSP) but with multiple salespersons doing the traveling.

There is an Excel sheet for solving such problems, and if one wishes to go further, the basic heuristic and metaheuristic algorithms are not that hard to implement either.

"Higher Wages" is almost never the answer for finding more candidates.

The only way higher wages lead to more candidates is by taking them away from other companies or other industries, and sometimes from other countries. So that is sometimes an option for certain employers, but not for an entire industry. It's a myth that there is a pool of workers who is "underemployed" because of low wages.

Also: In a free market, if companies can earn more profits by hiring more people by offering higher wages, they will do so. But increasing wages also reduces profit, and there just may not be enough room in the margins.
Netwerk24 does that in South Africa. They bundled 11 Afrikaans magazines and 35 newspapers under 1 account. And you pay R99 per month for access. (About 7 USD)

Not a bad price, but I don't give a shit about all of those newspapers and magazines. I just want 1 or 2 and I don't want to pay for all of them.

My proposed solution is very similar to the old print days. You used to just buy a single copy of a newspaper. On an adhoc basis, depending on whether or not any of the headlines caught your attention. You didn't buy a single article, nor did you subscribe to multiple newspapers. (you could, but I don't think many people subscribed to multiple)

So here is my solution for a digital version of this:

- You have an account with a digital news agency (or group)
- You buy bundles of articles. E.g $1 for 20 articles. (or whatever price is appropriate)
- Everyone has access to the website, but you can just see the headlines/opening paragraph.
- If you are interested, you can use one of your article credits to 'unlock' a specific article and read it in full.
- Once you have 'unlocked' a specific article you will always have access to it, and your credit for that 1 article is used up

This way you don't have to bother with microtransactions, and also you don't have to bother with paying for a whole bunch of stuff you don't want.

What do you guys think?
If the only recourse for a defrauded buyer is either to simply eat the loss or lose even more money, that's not what I'd consider an acceptable solution that's competitive with other, non-crypto means of payment. It's a solution that does provide some disincentive against fraud, but it's significantly worse for most consumers than the current status quo.

Of all the things to blame the media for, being too critical of Clinton is an unfamiliar one to me. Especially when conventional media sources were clearly hostile to Trump but enamored with Trump stories.

If we are going to blame the media for something, it should be feeding the trolls, which it still has a hard time with to this day. Trump got incredible amounts of free press despite having much lower funding levels than Clinton.

We could call the email controversy uninteresting but it is clearly a story about corruption and unevenly applied laws and regulations. The story was about the corruption and cover-up, not IT infrastructure.

Was tempted by their product but I had to cancel my account as their IMAP integration was quite lackluster. Their support was prompt and courteous though.

When setting up a basic script to save attachments to a Dropbox, two basic thinks it could not do:

- Treat attachments individually (they all got dumped in a ZIP)

Zapier told me their gMail integration is better. But IMAP is the open standard.
Headers are used control visibility of declarations (note though that visibility of symbols themselves is controlled by other means), and typically contain more than just function declarations (structs, enums, etc.). There are basically two common patterns to split public and private declarations:
- public header for consumers of the interface, private header for internal use only
- public header for consumers, private declarations directly in the .cpp/.c file

It is true that such problems /can/ be solved via mathematical linear programming (for those coming outside math circles, please note that the term programming here has nothing to do with coding) and this is how they are usually presented in academia. However, in practice, it is not something one would be advised to do. Usually, the complexities of the real world routing and scheduling make it impossible to solve these models of practical size. Therefore, numerous heuristic and metaheuristic algorithms have been proposed and are usually used in practical applications. These usually are sound familiar to those that have some experience with "old" AI: genetic algorithms, ant colony systems, simulated annealing, and even neural networks have been succesfully applied to provide "good enough" solutions to these problems.
This is my biggest concern about 2FA. On Google I have TOTP 2FA enabled, with my phone number as a backup. But everything goes through my phone - I'm not really worried about some stealing my phone to gain access, but what happens if I break or lose my phone.

A few years ago I was travelling abroad and had my suitcase stolen - which had my laptop (with FDE) and passport inside. Fortunately I had my phone and wallet on me, otherwise I really don't know what I would have done - I probably wouldn't even have remembered the name of the hotel I was staying at that night.

But we're not in a truly free market, are we? And we've already seen huge tech companies band together to keep profits artificially low. And that's just the one's that got caught.

> But increasing wages also reduces profit, and there just may not be enough room in the margins.

Corporate profits are at an all time high, and have been for quite some time. We're paying C-level executives insane amounts of money. Profit margins are surely not the issue here.

Of all the large and popular sites that support U2F, the only one that I'm aware of that only allows one key is Twitter.

Technology After the Great War
There is this trick among us operations researchers I'd like to share: even if one is able to perfectly model the peculiarities of a given application and get the optimal solution, it should not be the only output. Instead, one should put forward several good alternatives which the stakeholders can then discuss and become proponents for.

Nobody likes the scruffy operations researcher who awkwardly tells decision makers what to do in the form of an optimal solution, because this takes the power away from them. However, if one presents several good, preferably nearly optimal but different to each other, solutions between which the decision can be made freely, you have a better chance to make a change to better.

I may be naïve, but the idea was that the first paragraph would probably tell you whether reading the rest made any sense; my reasoning was that if you pay a flat fee which the content providers fight over based on what is being viewed, you do not care what you click - but the other side has everything to gain by making you click.

With micropayments, you can at least hope that content providers will be wary of leaving customers with the sense of being fooled into paying for a story.

The keyword here being 'hope'. Sigh.
Teenage pregnancy-how to make kids familiar with it?
That and the fact you can speak to engineers at Microsoft will relative ease. Recently had an Azure support ticket open. The whole process was beyond my expectations to the point I'd have difficulty putting anything big anywhere else. Could be personal preference, but the way they manage introducing new services and grandfathering old ones is also very good.
That's one loop of the self-balancing process - if there's a scarcity of labor, wages go up, some businesses can't afford it and close down, that reduces the needed number of workers and solves/balances the scarcity.

And it's a beneficial process, as it moves these people from business where their labor is less valuable (as evidenced by the fact that it's not profitable to employ them at a slightly higher wage) to businesses where their labor is more useful. The least efficient businesses being forced to close is a good thing that allows the labor, facilities, land, materials, capital, etc to stop being used poorly so that they can be used better in the economy.

The other balancing loop is that higher wages in some field is motivation for people to get the skills needed for that field, either through choice of education for younger people or by transferring from another type of job. This balances the supply side in a beneficial way, but as it's much slower than the balancing loop above, the largest immediate impact comes from the demand-side balance.
You might already understand this point, but I thought I'd mention it anyway.

Because we're social animals and most people don't have the ability to simply ignore harsh/insulting/whatever words directed at us.

It may well be possible to develop the ability to ignore such words, but if it is, that's an ability that would take a fair bit of time to develop, so is out of the reach of most people right at the present moment.

>You can apply the exact same logic to absolutely anything.

Of course. See my other post where i mention capital investments for example.

> E.g. if your cost of materials increases by $20 instead of your cost of employees.

yep. in case of 20% tax the net cost of the materials is $16, in case of 30% - $14.

>This doesn't mean you're paying more, or less, for these materials - simply that are not obligated to give away as large a share of your profits from any change in costs.

call it any way. In the end paying $20 for materials results in $16 decrease to the resulting after-tax business profit in one case and $14 decrease in another. Thus the materials became $2 more expensive to the business.
Ask HN: Has anyone used security orchestration
Hi I am looking for what you have experienced. Practical challenges you have faced when implementing orchestration to your workflows.

Finally, for discussion, do you think it actually solves many issues for a small team or does it create more headaches.
I wrote ocaml-bitstring (based on Erlang) and it also works by generating the code to handle the bits at compile time. It's fully general too - eg. if you describe a structure of 1 bit followed by an array of bytes then it will add the necessary bit shifts automatically when reading the bytes. Or if you describe a struct where everything is aligned then at compile time it will generate the most efficient code. You can even have variable length bitfields (a huge headache when implementing, but it does deliver the best possible code based on what it can prove at compile time).

I am making no claims about priority of problems, so I certainly welcome identification of other issues and proposals to improve them.

If we mentally subdivide all commercial activity between traditional/centralized/blind trust commercial activities and novel/decentralized/cryptographic trust commercial activities, then (even if it is not occuring yet) it can desirable for the supporters of decentralization to be able to assure themselves that the status quo can not undermine the economic value of the cryptographic trust community.

Even outside of cryptocurrencies we have debates about net neutrality, priority of packets etc... One could similarily wonder if current delivery services are able to say profit by investing in specific companies within a sector of products, and differentially prioritizing the delivery of their goods (or gentleness of delivery for fragile goods, or even non-delivery).

I don't believe in moot points, people can work on different issues, design solutions for them and then they can look at how to intersect/generalize their protocols so that it displays both or more desirable traits...

At least in boat building you can either have:

B. Boat mass produced by a company of hundreds of years of tradition and knowledge.

With some rare exceptions, you'll always want the second option. The bugs have been worked out, everything is ergonomic and safe. Easy to find parts even if they are of inferior quality.

I really don't get why houses have such a special attention. It's the most expensive possession people can have and they wanna build in a way that it's even more expensive and prone to error. Imagine if everyone built their own car...
> Take SV elites for example. Bezos, Zuckerberg, and Dorsey seem out of touch in a way Rockefeller, Carnegie, and Ford did not.

You are not comparing like with like -- you even give it away in the tenses that you use.

The first three are not like the last three. Rockefeller came after Ida Tarbell after she investigated his trust and exposed some of the methods used by Standard Oil. Carnegie went to extensive lengths to break worker unions. Ford allowed his name, negligently or otherwise, to be put against a series of antisemitic articles that were published in 1920s Germany.

The first three have spent considerable money on philanthropic efforts that serve to bolster their names.

The last three haven't yet. They've still got time. We may know what's made them unpopular now; we don't know what will make them revered in a hundred-years time when any controversies will be lost as little insignificant details in time.
