On his laptop, [[Cueball]] explores a cyclic path along which his files are being copied from storage to storage. His laptop (presumably the one he is on) is sending its files to a server, which sends its files to ''another'' server, which in turn syncs back a certain selection of files to his laptop. Cueball determines that this setup leads to an exponential growth, implying that each node in the cycle simply copies files over to the next without any effort to avoid duplicates. Indeed, each time a set of files completes a full cycle, duplicates of the same files are propagated. | On his laptop, [[Cueball]] explores a cyclic path along which his files are being copied from storage to storage.

β | {{w|Moore's Law}} is an observation in computer | + | {{w|Moore's Law}} is an observation in computer science that states that the number of transistors we can fit in a chip will double approximately every two years. Cueball, who was rather alarmed, calms down when he realizes that the exponential growth of his backup is slower than that of Moore's Law. He reasons that as long as he keeps at the forefront of information storage, he will never run out of room. Assuming available disk capacity is proportional to number of transistors (this is true for solid-state disks), this would imply it takes more than two years for his files to completely propagate through two servers and back to his laptop enough times to double in size (implying either an extremely slow transfer or an extremely weird backup system). |
The phrase "[this is] why we can't have nice things" is often used in response to incidents where someone abuses a well-meaning feature, with the abuse ultimately wiping out any benefits the feature was supposed to bring. In the comic, the person off-screen is commenting on the fact that Cueball is not using advances in storage capacity in a responsible manner. That is, rather than using the increased capacity to store more useful information, he is simply using it as a workaround to avoid having to make his backup strategy more efficient. | The phrase "[this is] why we can't have nice things" is often used in response to incidents where someone abuses a well-meaning feature, with the abuse ultimately wiping out any benefits the feature was supposed to bring.
