1) Use [code][/code] tags around your code to make it visually separate from the rest of the text. 2) I'd recommend explaining the concepts more in depth. You never really answered the question "So how does grayscale work in Axe?" beyond "Use another buffer." Why does having another buffer allow greyscale? The same goes for the Line() function that you say doesn't actually draw a line. A user who doesn't understand that Bresenham's Line algorithm is actually a numerical approximation to a true line is going to be very confused by that statement.
Overall, good job. Format it a bit more and we can add it to the tutorials section
Hmmm... I still get permission denied... as sudo. Edit: and as a standard user.
Are you running this from a device with a FAT filesystem? Linux will tend to return permission denied when the filesystem doesn't properly support permissions.
While I was taking a small Java programming test (I don't know even Java ), I came across an interesting problem called the equilibrium index. Basically, given a list such as {-7, 1, 5, 2, -4, 3, 0}, there is an index into the list for which the sum of the elements up to that index is equal to the sum of the elements after. For this particular data set, it happens to be at the indices 6 and 7.
Your challenge is to write a program in TI-BASIC (or Axe if you wish) that will compute the equilibrium index of any list. If it doesn't exist, then the program must return -1. You are allowed to assume that the list is in L1 and that the dimension of the list is in N.
NOTE: Don't use Google. As it turns out, a lot of people have unwittingly made a mistake in declaring the problem such that the example list has indices at 3 and 6. The index of 3 is actually only true when L1(4) is eliminated from the list.
Timing: It took me about three minutes to write the program and a further five minutes to notice the error everyone had made wasn't actually a bug in my program, but their mistake. It shouldn't take longer than half an hour max to do.
In response to the recent downtime on #omnimaga, several people have asked questions and voiced concerns about the security of the channel from takeover.
After a small debacle last night between Manager Eeems and CoT SirCmpwn ([email protected]) got out of hand, SirCmpwn shut down the channel and kicked all Operators. This resulted in approximately 37 minutes of downtime, during which the channel was relocated to irc.omnimaga.org (port 6667, #omnimaga for future reference). This was fixed by our kindly forest squirrel, Cooliojazz and the channel is back to normal. SirCmpwn also attempted to delete the Axe Parser releases thread, but Juju easily undeleted it. SirCmpwn has been banned, security measures are being discussed and implemented that will hopefully prevent this terrible occurrence in the future. We apologize for the discrepancies in the logs and any inconvenience this downtime may have caused.
We might make irc.omnimaga.org, also known as OmniNet, our main IRC server for more security. Unlike EFNet, OmniNet have services, which can protect your nickname from impersonation, much more features and the servers are ran by Omnimaga staff, which is obviously not the case of EFNet. Please give us your feedback in the comments EFNet and OmniNet are already linked together with OmnomIRC.

Sorry to disappoint you, but verifying perfect squares is still far too computationally intensive to be practical.
To quote part of my post from the other page on the scale of the problem:
Quote
Given the current 2048 bit keys and classical computations, the scale of the problem is vastly more difficult than even the largest keys broken today (768 bits). By vast, I mean volume of the known universe measured in nanometers cubed vast*. The chance that anyone will solve it is so exceedingly slim that the only mathematical tool I have available to calculate it has to work with arbitrary precision operations simply in order to present it. Unless someone gets their hands on a massive quantum computer running Shor's algorithm**, it is, in short, an impossible problem.
*Even this is an understatement.
**It'd take about 30 seconds for a quantum computer to break the code, since the computations necessary increase according to (lg n)^3 for an n bit key.
Basically, trial integer factorization isn't going to work.
