Heno Heno

Sometimes at lunch, I get a serious craving for a simple Japanese rice bowl. Amazingly enough, there’s a place close enough to me to satisfy: Heno Heno. It’s a simple japanese restaurant with a single row of stools at a bar and a few tables to the side. The food is simple: a single page menu describes the treats to be ordered and everything is thrown together quickly right in front of you.

There’s nothing like a hearty bowl of thinly-sliced beef and rice (Gyu-don), or delicious nukazuke (fresh homemade pickles), or the freshly made sake o-nigiri (salmon rice cake in nori seaweed wrapper).

Perhaps I should let the food speak for itself:

Website Backup With rsync

One thing that kept me from getting my blog back up for a while was the lack of a consistent backup strategy for the WordPress content and the website as a whole. Website backup should be easy, with these commands and the following script, it’s very easy.

This is just a starting point though, I have some ideas about backup that I plan to explore in future experiments.

Straightforward Android Native Executables

I spent some time trying to figure out how to build a native code “Hello, world!” program for Android and noticed that prior to the r4b release of the Android NDK, there is a lot of bad info out there on how to do this. Usually, it involves using some kind of unofficial cross-compiler, plus the entire source tree of the Android OS, and/or whatever other kludgy hacks like linking the executable statically to some kind of ARM libc. This seems bad. With the newest version of the NDK generating a proper gdbserver executable and gdb setup stubs, why anyone would want to do this by hand is beyond me.

There was a script that made sense at one point: agcc.pl (here), which essentially takes all of the Makefile fragments and command-line switches and wraps them for you, letting you treat the NDK’s cross-compilers almost like a normal gcc, but this is probably still more work than it’s worth.

The Easy Way

The easiest way to get the NDK to build a native executable for you is just to use

at the end of your Android.mk, and then build like normal.

Anything else will just cause premature baldness.

Geocoding with Mapstraction v2 and Google Maps v3

There isn’t a whole lot of info out there about how to use Mapstraction, especially the v2 API, so here’s one thing I’ve had to pick up along the way.

I spent a little time hacking together a geocoder module that uses the Google Maps v3 API, but was having to track down why it wasn’t loading properly. Continue reading Geocoding with Mapstraction v2 and Google Maps v3
