Tar options are actually very easy once you take the time to understand them. Want to create an archive? use `-c`. Want to extract? It’s `-x`. From that you know you can use `tar -cf foo.tar foo` (`-f` lets you pass the archive name) and `tar -xf foo.tar`. Want to be verbose? Add `-v`. Want to use gzip compression? Add `-z`. There are a bunch of other options to do more, but just with that you can already understand 99% of what tar is used for.
Services are almost always structured as subscriptions. In your case, there's a big question of whether you should use a flat price or charge as a multiple of the products that are being updated with your service.

Unfortunately pricing is really challenging and complicated, and the only way to get it right is to survey and A/B test.

One thing you need to know is this: what's the average number of products a developer creates? If the answer is 1.5, then you wouldn't want to do a "first product updates free" model. But if the answer is 5+, then you have nothing to lose by letting them test out your service with one product before adding the rest. (But then they could also be really shady and use multiple email addresses, so you'd have to verify identity somehow.)

If you're surveying users, you should also ask what they'd be willing to pay. There are probably best practices for how to ask that question, and I don't feel qualified to tell you what I think.
I don't understand why you're getting downvoted. Even though I would personally never use PHP for anything, your statements are accurate.

The issue I have with this kind of projects is that people quickly accept that reading manpages is boring and that they should only use `tldr gcc` or a quick stackoverflow lookup instead of actually learning how to use their tools. It’s like learning how to fish vs. bying fish at the supermarket. Sure, if you know how to fish you can still buy at the supermarket if you’re lazy. But if you don’t you’re stuck with what’s at the supermarket.

Instead of

cos(...)

you could use

pow( cos(...), a )

where a can be used to adjust the steepness.

I can't plot it right now and I think I'm missing something, but you get the general idea of using the power of a function which goes form 0 to 1 to adjust steepness.

Another solution would be a 2-piece function kind of

0.5*pow( 2*t/T, a ) for t < T/2

and

1-0.5*pow( 2*(1-t/T), a ) for t > T/2

which makes a similar slope as the cosine but is easier to calculate.

Where to Buy the Cheapest CPC Ad Clicks?
Let's say CAs continue to issue SHA-1 certificates and fail to do the recommended Legacy Validation but just issue the certs. Let's further assume that clients which still get updates are updated to not accept SHA-1 at all any more.

Wouldn't that be enough already? Newer clients wouldn't be able to access sites that exclusively serve SHA-1 certificates, so that's the loss of the site-owner to only and unconditionally present the SHA-1 cert. IMHO no special handling on the side of the CA is required here.

I see no potential for a downgrade attack because a current client would only support SHA-2 anyways, so trying to MITM the connection to pretend the client supporting only SHA-1 in order to induce the server to present the SHA-1 cert would only lead the the up-to-date client to reject the connection.

However, if the site presents a SHA-2 cert where possible, falling back to the SHA-1 cert, then old and unsupported clients would still be able to access the site. Yes, the security would be reduced and it would certainly not be sufficient to protect against state-sponsored attacks, but it's still way better in protecting against FireSheep-like attacks done by individuals.
It would be cool if there was a complementary app that goes like this:

It teaches you using a hands-on approach about coding/algorithms/sys admin from beginner to expert level. Then it offers you a bunch of roadmaps on what exercise you should do next to build on the current skills you have.

Even more it would be cool that it would find the weak spots on your current skills and allow you to go back to previous exercises to improve that skill.

Wouldn't that be helpful?
How Blue Lights on Train Platforms Combat Tokyo’s Suicide Epidemic
Man pages are manuals.

They list all possible ways of controlling the program. Have you seen the man page for curl? http://man.cx/curl

If we accept that man pages shouldn't be less than a manual, how then to deliver the top n recipes that demonstrate how the program can be used in the majority of cases?

In the case of curl, it's really just a GET, a JSON POST, a file upload... and perhaps add in an auth header or non-standard header.

Example: http://stackoverflow.com/questions/356705/how-to-send-a-head...

458 people upvoted that question, 697 upvoted the answer, hundreds of duplicates of it point to it.

In a long man page, well-documented options might as well not exist.

You don't need the whole manual all the time, and when someone is busy getting something done they shouldn't be hit with a "Hey, why don't you learn all of this"... they just want to get something done.
I honestly don't understand the meme of "tar is so hard to use". You only need to know like five parameters (xcvfz) for 99% of use cases, and they're pretty easy to understand.
Seems like a good idea, man pages can be almost comically obtuse at times.
I strongly believe that there is a niche for a q/a site with less focus on bureaucratic management of counter-productive rules.

I mean, whoever does this might have to hire their own dang-like supermod but I refuse to accept that what we see today is the only option.

Some ideas:

* don't make bureaucratic powers a reward

* when the map and the terrain doesn't match the terrain is usually correct. When the time after time you find that the most useful questions are closed as not constructive then maybe the rules for "not constructive" needs to change.

* from other forums: encourage newcomers to use nicks that don't identify them at least until they get a feel for it

That's not the experience of many people. Or maybe, "taking the time to understand them" is not how they want to spend their time, and the mnemonics are bad because the use is not that frequent anyway.

One thing I love about Perl, which has seemed sorely lacking in many other languages, is the habit of documenting all modules with a "Synopsis" section, which is essentially short examples of use. A good 50% of modules I use I don't need to read further!
I do find TLDR useful, but is there anything preventing adding it as a standard section of the actual manpages we all use?

Perhaps with a switch (man --tldr) or something?

Wouldn't a project to add those short examples to manpages be good?

This is very fascinating, new mechanical approaches proliferate!

Koenigsegg has the total opposite approach in their hybrid Regera supercar: no gearboxes at all. Low speed high torque is delegated to the electric motors, and the internal combustion engine only engages after a certain speed.

If you're already down to the command line, running UNIX commands, and using TLDR you are way beyond "buying fish at the supermarket".

And why should you "learning how to use those tools", when what you really want from those tools are the use cases TLDR already covers?

The BBC has just run an interesting TV series where a doctor visits families in their homes and improves their health by changing their diets, and adding exercise. The results are both visible and -- importantly -- measurable.

The series is going to be repeated in January so UK residents will be able to watch them.

http://www.bbc.co.uk/programmes/b06q6y95

Of course, medical advice on diet hasn't always been entirely correct, but I think there's a pretty broad consensus on Dr Chatterjee's approach -- cut out the fast food and processed foods, avoid added sugars, cut carbs, eat more veggies and fibre, eat a wider variety of foods etc. You don't really med school training to figure this out.

tl;dr holy moly! In late '80s US government prevented Japan exporting cheap DRAM into US (free trade anyone?). DRAM prices went through roof. Atari covered holes in its own finances by reselling DRAM to major manufacturers (SUN etc). The DRAM they resold was "smuggled" in outside the official agreements. The sites owner has this from FOI requests.

This seems plenty plausible - and is one of many many reasons the WTO was a good idea.

But boy, Atari smuggled DRAM ... Weird

It's not clear what you mean by "this". You might mean this small section that you quoted, or you might mean the entire article to which this is an opening preamble.

If it's the first of these, then here's a free translation:

A talk like this can convince an audience that the
conjecture is just a wild, crazy thing, produced by
wild crazy people, and it comes from nowhere, without
motivation, without provenance. If so, you'd have to
believe that number theorists are wasting their lives
chasing bizarre and pointless things, and really, not
many of them either.

I hope that this article *fails* to make you think
that. I hope this article shows you that the BSD
conjecture is a part of a larger, meaningful context.

On the other hand, if your "this" refers to the article itself, then it's a rather larger task to help access it. I attended a talk a while ago that gave an excellent, high-level overview of this conjecture and the work being done on it, and I can see the structure of the arguments here.

But it's not intended to be read like a novel by people other than experts in the area. If you're not an expert - and very few people are - it's an article you need to wrestle with, work on, and dive into.

It's math, it's not a graphic novel, and math is not a spectator sport. It's requires participation and effort.

So, is it the article itself for which you need an ELI5? If so, seriously, good luck. This is material at the very limits of modern math.
There is one other strength that PHP has which is not replicated by any other runtime on the web, with the partial exception of Perl: its execution model. PHP code is executed per-request only, as opposed to within the context of an already-running app server. This means your PHP app has no state beyond what you explicitly build into it during each request, and this makes reasoning about state and control flow very easy. I love how this makes debugging, optimizing, and scaling, much more natural.

This is the reason why PHP is still my go-to first choice when it comes to request-based server apps (and together with Node.js it's also a good option for continuously-running applications). For me, the sore points of PHP are its syntax, scoping behavior, and the awkwardly structured standard library - to the point where I occasionally look elsewhere, or consider building an alternative myself.
For some reason, I can't remember for my life how to use cpio, which I find worse than tar even though it has less options. I always mix up input/output mode, and I never remember how passthru mode works exactly.
A statement that a list of rights is non-exhaustive does not mean they are limitless. The purported right must be found somewhere else. E.g. Buying alcohol on Sundays is not prohibited in the Constitution, but you don't have a right to that because blue laws were accepted at the time.

Your idea of limitless rights turns Constitutional democracy on its head. Rights are exceptions to the power of the majority to regulate society. Limitless rights curtails democracy to nothing.
This is well-written, and seems to touch on some vital part of our current cultural dilemma: when we finally manage to make freedom and relative prosperity available to almost everybody, how do we then handle that freedom and prosperity? How do we manage our time, when so much of it is our own, as compared to most people who came before us? What choices do we make, every day of our lives?

I'm no psychiatrist, but I see bad choices and unhappiness every day. I barely escaped that fate, myself, and it's an ongoing struggle, of course.

I always thought the admonition should have been rephrased: "With great freedom comes great responsibility." But that seems laughable in a world where so many people seem like confused children locked in a vicious cycle of desire and cheap gratification.

This reminds me of a few years ago, in almost every supermarket in China, there are third-party vendors selling electronic stuff also sells pirated MP3s and videos, for 5 Yuan(~84c) they'll load up your iPod Classic/MP4s(how video player called in China, as succeeder of MP3) with titles of your choice.

Until Apple has enhanced their DRM in apps, if you buy iPhones/iPads from a third party "authorized" resellers, you could ask them to install any paid apps, and/or jailbreak your iOS. Only difference was those kiosks are fancier.

But days are better now, I see people around me are starting to pay for Music and Applications, at least in larger cities.

I don't get why an installer would ever load an external dll? The installer should bundle all of its own logic AND all the code of the application it's installing. That's kind of the point of making an installer in the first place. When is it useful to have a dll next to an installer (for non exploit purposes)?
