slopefields.py (1.9 KB) Now you can generate your own slope field / vector field / direction field of a differential equation using open source python and gnuplot! Set function to draw field of under dy_dx(). Set window parameters (x/y minimums and maximums, intervals, and length of field arrows). Run with to generate the slope field.
You need at least mingw-w64 rev 5579, build-essential, and a working compiler. Replace the demo prefix /usr/i686-w64-mingw32 with whatever you feel like, if you want to. Extract the gcc tarball, and pull in mpfr, mpc, and and gmp tarballs under the extracted gcc root. And just for fun, let’s test it: Bibliography: http://pete.akeo.ie/2010/07/compiling-mingw-w64-with-multilib-on.html http://mingw.5.n7.nabble.com/Rantings-of-a-crazy-dude-on-GCC-NO-EXECUTABLES-td20091.html http://email@example.com/msg02903.html
The iBus input method does not work with the compose key - see Debian bug #591459 and Ubuntu bug #493766. It seems that iBus is intercepting all keystrokes and substituting its own instead, even though xev shows the Multi_key and accent being produced. For example, Multi_Key + ‘ + e leads to ‘e instead of [...]
Skip to the rooting process, if you wish. The iPPea TV is a pretty neat gadget, to say the least. The USB-stick sized device features a full Android 4.0.3 OS, a 1Ghz Ingenic JZ4770 MIPS processor (complete with FPU!), 512 MB of RAM, 2 GB flash storage, and about 800 MB of internal memory. Overall, [...]
Sometimes, you might need to keep things simple. Here is a very simple su implementation written in portable C that can be used on almost any architecture - e.g. Embedded Linux, Android, Windows, etc as long as it supports C. It is licensed under the 3-clause BSD licence so any use is OK as long [...]
After ./configure and make, you get this interesting scenario: The solution?
The story so far… File series fully applied (no output) # On branch master nothing to commit (working directory clean) What’s happening here? Well, it turns out that we need to reset and clean the .pc directory of quilt: Now, let’s try applying the patches: Applying patch patch-number-one.patch patching file configure.ac Applying patch fix-build.patch patching [...]

There appears to be an obscure bug that has somehow recently activated on ARMv6, non-FPU builds of VLC for Android. This has been only observed on Android 2.1 and possibly on other Android 2.x platforms with ARMv6, non-FPU builds Android 2.2. On the other hand, it works perfectly on an Android 4.0 on a NEON [...]
By default on the latest versions of Debian and Ubuntu, the gconf preferences “/desktop/gnome/interface/menus_have_icons” and “/desktop/gnome/interface/buttons_have_icons” are set to false by default. Despite this, GTK2 and GTK3 applications both display icons next to their menus by default. However, Qt4-based applications such as VLC media player don’t display icons. To fix this: Or, open gconf-editor and [...]« Previous Entries
