For programmers a repository is a database where programs are stored. It’s tools for the sake of tooling, rather than tools as helpers to build something else. Riemann Integration Stokes’ Theorem??? By the way, the Android story actually happened to a friend of mine just as told. Most people I know that have to ask for computer help couldn’t read a flowchart in the first place. Description of the boxes [ edit ] There are 18 boxes in the chart, but only 12 different texts.

It would be quicker to try Wolfram Alpha instead of installing Mathematica, which uses the same backend for mathematical calculations. Specialists and renowned experts being bothered – not to their amusement – by strangers, often at highly inconvenient times or locations, is a common comedic trope, also previously utilized by xkcd for example in This step in the flowchart is to install and use Mathematica to do the integration for you. Navigation Main page Latest comic Community portal xkcd. An application designed to automatically download and install new versions of an already installed program. I’m not sure that’s true. The top left is the most active with two entries and three exits making it the second busiest box in the chart.

This intuition is shown here in the form of a diagram. Does that make sense? I’ve restored your definition. Product rule For any andit follows that.

Partial fractions is a technique for breaking up a function that comprises xkxd polynomial divided by another into a sum of functions comprising constants over the factors of the original denominator, which can easily be integrated into logarithms. How do I print out a flowchart?

# Tech Loops – explain xkcd

This may refer to the burning of one’s work to avoid the shame of being associated with such a badly failed attempt to solve the given integration problem. This is in contrast to the simple, straightforward flowchart for differentiation. Alternatively, it could be an ironic hint to the fact that in order to find the integral, it may even be necessary to break the law or upset higher powers, so that the negative consequences of a persecution can only be avoided by destroying the evidence.

Riemann Integration The Riemann integral is a definition of definite integration. But most important is the bottom right library that starts everything since this is the only of the interconnected boxes that does not itself have any entry.

All the other stuff is thus only there to make it possible to use the computer for these purposes. Symbolic algebra is the basic process of finding an antiderivative function defined with symbolsas opposed to numerically integrating a function.

# Tech Support Cheat Sheet – explain xkcd

Please help editing it! In that broad sense, everything that we do is merely “maintaining a huge chain of technology solely to support itself”.

Alternatively, the reference could be seen as a joke that integration might as well be a symbol, soving in a novel, because Randall can’t get any meaningful results from his analysis. Now I feel like the first explanation was awfully worded and this one says about the same thing but fits much better.

## 627: Tech Support Cheat Sheet

The updater has one entry from a tool, but also exits to another tool. It’s ’cause you’re dumb. Thus the information stored here never leaves; this means the programs stored in the repository are not used.

But on the other hand, then the box with things flowcharf actually wishes to use the computer for, is then not disconnected from the rest, but an integral part of it all. Reminds me of https: This step would indicate that the flowchart user, desperate from failed attempts to solve the problem, contacts some more skilled mathematicians by phone, and presumably asks them for help.

Please edit as you see fit. Navigation Main page Latest comic Community portal xkcd. Although “DLL” is a term used by Microsoft Windows, all modern operating systems use dynamic libraries, each with its own name.

It looked good to me at that time mostly justified by the “things I actually want to do with my computer” bithowever the “new” explanation by Ralfoide looks much better now, so probably mine should be just deleted I’m not doing just that right now because I lack the time to search for useful bits to keep, if any. I’m the author of the original explanation that about Android things. It’s easy to forget why we do things in life.

No [Arrow returns to “Try applying” step. I thought I could contribute to the article with a better explanation of the Risch algorithm, since I have a bit of expertise here — I’ve read all the original papers, plus the Cherry papers that add the extra features like Li and erf.

Two are not connected to any other boxes.

## 2117: Differentiation and Integration

Sinceit follows that by integrating both sides you getwhich is more commonly problsm as. Make of such a result as you will, but I suspect if that happens for printing out that flowchart, it doesn’t speak well for one’s ability to become more tech-savvy.

After the first step of integration, Randall assumes that any integration can not be solved so simply, and then dives into a step named “????

For programmers a repository is a database where programs are stored. Here, however, Randall finds he’s spending most of the time using his computer just for the sake of maintaining the OS or the hardware on said computer.
