Alchemy can be done. Gold has been synthesized on the nuclear level by way of neutron bombardment of other elements. It's just not economically practical since the process costs more in equipment and energy than the value of the gold. ht

And to tie this back into the financial domain, company stock prices are also not open-ended but a bounded domain. Below $1 gets you delisted from the exchanges; above $500 or so starts to impact the stock's liquidity.* Companies make sto

If you want a "seriously hard" puzzle for optimization testing, scale up. What happens if you feed the program a 16x16 or 25x25 or 100x100 Sudoku?

> There's nothing inherent about usability that requires jailed computing. Not a requirement, but there is a correlation. Programming for an unjailed ecosystem takes more effort to support the vastly wider environments on the devices.

The big UI annoyance is that assumption in #2. Most of the time you did drill-down into this folder from its parent so "back" goes "up". But when you didn't (which could have been hours ago), you get a very jarring disorientation. Comical

Another solution is a custom style sheet. Opera has had that capability forever, since about 2001. I use Opera for most browsing, with a custom style sheet to force all text to a certain font and style. This varies by device: Calibri 12p

You misinterpreted me. What I said is that the extra effort needed to report this vulnerability isn't a fault of the Amex customer service system. Of course it's a faulty deployment process that allowed this to happen in the first place.

This is not correct. If a Sudoku puzzle has one and only one solution, brute force can always find it. It is trial-and-error for every single cell and every possible value, which is guaranteed to succeed eventually. Sounds crazy for a hu

The problem here is that the number of intersections scales quadratically, as the square of the number of roads. Each intersection cuts the capacity of the roads and represents a potential cause of gridlock and accidents.

One thing that Dropbox doesn't do well is file segregation Dropbox does do that. In the preferences, each folder has a checkbox for "Sync this folder to this computer"; uncheck it and the folder won't be on that device. It's marginally

Looks like bubble sort is so slow because this implementation has a very high ratio between the costs of a compare and a swap. A swap involves redrawing large parts of the graphical area, while a compare is fast. Bubble sort makes N^2 swa

You also have to figure it's very temporary root access, until a real root user repairs it from an uncompromised offline backup. It's not like they're selling the entire MySQL site in perpetuity for $3k.

We already know that the inner loop runs in O(klog(n)). Since we've just added a loop around that, it's easy to see that the whole thing runs in O(mklog(n)) time. This is not necessarily true for all cases. (It is for yours.) It's possi

It goes both ways. The distinction might be efficiency of profit per capital and time invested. Something like patio11's bingo card maker, which makes money out of almost nowhere compared to its cost, works well only if small. But that

How about more modern science fiction? I loved the Golden Age series by John C. Wright, published around 2004. It's refreshing to read sci-fi where computers and connectivity are ubiquitous, rather than the old masters who didn't foresee
