I couldn’t find a list of the results of FileSystem.supportedFileAttributeViews() on various operating systems, so I made one: UnixFileSystem/BsdFileSystem/MacOSXFileSystem: “basic”, “posix”, “unix”, “owner” LinuxFileSystem: Unix + “dos”, “user” SolarisFileSystem: Unix + “acl”, “user” WindowsFileSystem: “basic”, “dos”, “acl”, “owner”, “user”
I was trying to build Apache Hadoop 2.0.3-alpha with the ARM Java 8 Preview (to test out hard-float build support, which needs a Hadoop build fix), and I hit a compile error in InputSampler.java in the Map/Reduce code. It seems that the Java 8 compiler won’t allow a raw type to be used in a …
With the demise of FolderShare, I’ve found it rather difficult to keep my music library synchronized between home and the office. While there is software you can buy like SuperSync, you can pretty easily achieve a more general solution using free software, with the added benefit of universal OS support (e.g. Windows, Mac OS X, …

If you’re like me (and condolences if you are), you’ve often started a local Git repository for a new project, and then later wanted to create a shared upstream repository on another computer. (GitHub walks you through this, but let’s assume you want to manage the shared repository yourself.) Before I knew Git very well, …

This is a note to myself as much as anything, since it took a minute to get the command right, but maybe someone else will find it useful. The following command will dump the cache hierarchy for CPU 0 in a fairly readable format (though I truncated the shared_cpu_map entries by hand for purposes of …

The Sanmina-SCI stock I foolishly purchased through their Employee Stock Purchase Program is currently trading at a third of its purchase price. Now, to add insult to injury, I see that E*trade (the broker Sanmina used for the ESPP) charged me $20 for the 6:1 reverse split last August. They call it a “mandatory reorganization …
After much googling, I could not find any tools for converting a UTF-8 string into an escaped C/C++ string literal suitable for pasting into an ASCII source file. Therefore I produced this Perl script which seems to provide a fairly readable escaped string: use strict; chomp; print ‘”‘; my $prev_esc = 0; print map { …
I just read the Senator’s health care column from yesterday. The 4th and 5th paragraphs The Administration’s proposal contains tax penalties and fees on small businesses that are not able offer health insurance. To pay these added costs, many small businesses could be forced to decrease workers wages, hire fewer employees, implement layoffs, or cut …

Building Boost for 64-bit Windows turns out not to be completely straightforward. These instructions assume you’re using Visual Studio 2008 and running from a VS 2008 x64 Command Prompt. First, running bootstrap.bat appears to fail: Building Boost.Jam build engine Failed to build Boost.Jam build engine. Please consult bjam.log for furter diagnostics. You can try to …
I couldn’t find any instructions for building Expat for 64-bit Windows (x64), so I updated the 32-bit projects files myself: expat-vs2008-x64.zip. See my projects page for brief usage instructions. Update: With the March 2012 release of Expat 2.1.0, Expat now supports building with CMake, and these build files are no longer necessary. After installing CMake …
