Just had to create a median function in Python. We compute median values by ordering them and choosing the middle one.
I found a routine, but it lacked unittest coverage and the edge case of an empty input array. So, here goes:
import unittest
###############################################################################
def getMedian(numericValues):
theValues = sorted(numericValues)
if not theValues:
return None
if len(theValues) % 2 == 1:
return theValues[(len(theValues)+1)/2-1]
else:
lower = theValues[len(theValues)/2-1]
upper = theValues[len(theValues)/2]
return (float(lower + upper)) / 2
###############################################################################
if __name__ == '__main__':
unittest.main()
###############################################################################
class TestCommonUtils(unittest.TestCase):
def test_trivial(self):
return True
def isValid(self, functionName, valueShouldBe, valueIs):
assert (valueShouldBe == valueIs), "ERROR: Function %s returned value %.6fs, but value should be: %.6f." % (functionName, valueIs, valueShouldBe)
def test_getMedian(self):
self.isValid('getMedian', 2.5, getMedian([0,1,2,3,4,5]))
self.isValid('getMedian', 2, getMedian([0,1,2,3,4]))
self.isValid('getMedian', 2, getMedian([3,1,2]))
self.isValid('getMedian', 3, getMedian([3,2,3]))
self.isValid('getMedian', 1.234, getMedian([1.234, 3.678, -2.467]))
self.isValid('getMedian', 1.345, getMedian([1.234, 3.678, 1.456, -2.467]))

How to Build ZeroMQ (and Python binding) on AIX
Okay, so I may be stupid. I'm trying to run a Python script on an AIX box. In order to run it, I need a ZeroMQ (see http://zeromq.org). So, I'm trying to compile the zmq library using the standard compile-link-run thing.
BTW, this is AIX 6.1 using the gcc compiler [ TO START WITH ]
First, I had to get the sysadmins to install gcc and g++. then, I kept getting the error:
... checking whether we are using clang C compiler... no checking whether we are using gcc >= 4 C compiler... yes checking whether the C++ compiler works... no configure: error: Unable to find a working C++ compiler
Ug. Turns out, I didn't have libm installed. Some sysadmin time playing with puppet and NIM later, I have it. Now, I see:
... checking alloca.h presence... yes checking for alloca.h... yes checking whether SOCK_CLOEXEC is supported... no configure: creating ./config.status ./config.status: line 765: print: command not found ./config.status: line 765: print: command not found ./config.status: line 765: print: command not found ./config.status: line 765: print: command not found ... (times 200 or so)
Ah, fun with vi. Not vim, which tells you line numbers, just vi. Because IBM doesn't know from modern. So, I look up line number and find it's colon-number for go-to-line-number.
I look in the config.status line 765 (with :765), and I see it's referring to $ECHO shell var, I look for 'print' and find $ECHO is defined as:
... pic_mode='default' enable_fast_install='yes' SHELL='/opt/freeware/bin/bash' ECHO='print -r --' host_alias='' host='powerpc-ibm-aix6.1.0.0' ...
ECHO is 'print -r --' ????? Where did that come from?
So, I tried again, doing export ECHO=/usr/bin/echo first. No go. Next, tried with:
ECHO=/usr/bin/echo ./configure --prefix=/destination/directory
No go again.
-- time passes --
to fix this:
- in your ~/.profile or .bashrc, define:
CONFIG_SHELL=/usr/bin/bash
- Then, invoke ./configure as follows:
${CONFIG_SHELL} ./configure --prefix=...
Continuing, I found out I had to install:
- gnu automake
- gnu libtool
- gnu M4
Now, I'm stuck with:

Error message is:

Ug.
What to do? Punt.
I went to IBM's site and signed up for a free copy of their XLC compiler. I downloaded it and handed it over to the sysadmins, who did their magic to it. It comes in a package-thing that is only installable by IBM's installer, so this requires sysadmins.Once I had it, I changed my env vars to be:
export PYTHONPATH=/opt/recon/dcm/platforms/AIX/pylibs:/opt/recon/dcm/platforms/AIX/pylibs/lib/python2.6/site-packages:$PYTHONPATH export PATH=$PATH:/opt/recon/dcm/bin:/opt/recon/dcm/AIX/bin:/opt/recon/dcm/platforms/AIX/pylibs/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/recon/dcm/lib:/opt/recon/dcm/platforms/AIX/lib export CONFIG_SHELL=/opt/freeware/bin/bash export CONFIG_ENV_ARGS=/opt/freeware/bin/bash export PS1="[\u@\H \w]: " export CONFIG_SHELL=/opt/freeware/bin/bash export CONFIG_ENV_ARGS=/opt/freeware/bin/bash export CC=cc export CFLAGS="-qmaxmem=16384 -DSYSV -D_AIX -D_AIX32 -D_AIX41 -D_AIX43 -D_AIX51 -D_ALL_SOURCE -DFUNCPROTO=15 -O -I/opt/freeware/include" export CXX=xlC export CXXFLAGS=$CFLAGS export F77=xlf export FFLAGS="-qmaxmem=16384 -O -I/opt/freeware/include" export LD=ld export LDFLAGS="-L/opt/freeware/lib -Wl,-bmaxdata:0x80000000" export PATH=/opt/recon/dcm/platforms/AIX/bin:/usr/bin:/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/vac/bin:/usr/vacpp/bin:/usr/ccs/bin:/usr/dt/bin:/usr/opt/perl5/bin:/opt/freeware/bin:/opt/freeware/sbin:/usr/local/bin:/usr/lib/instlthen LOGGED OUT and RELOGGED-IN to pick up the env changes, and proceeded.
I then rebuilt libtool (because the aix version was way old) by doing the standard
${CONFIG_SHELL} ./configure --prefix=...
make
make check
make install
(and it worked!),
I re-untarred the zeromq library, and did:
${CONFIG_SHELL} ./configure --prefix=...
make
make check
but this failed. Problem was
make[1]: Entering directory `/opt/recon/making/zeromq-2.2.0/tests'

...
Long story short, the fix for this is:
We have to add the /opt/freeware/lib to the LIBPATH **** FIRST ****. Otherwise, it can't know to find the libcrypto.so.1.0.0 there. You'll get this same error if /opt/freeware/lib is there but not first in line.export LIBPATH="/opt/freeware/lib:/opt/freeware/lib64:/usr/lib:/usr/local/lib" and export LDFLAGS="-L/opt/freeware/lib -L/opt/freeware/lib64 -Wl,-bmaxdata:0x80000000"then, success:

PASS: test_timeo ================== All 9 tests passed ================== make[2]: Leaving directory `/opt/recon/making/zeromq-2.2.0/tests'
SUCCESS. Next, it's pyzmq.
Too much good luck now, I know this is going to fail soon.... And I'm right. Ug. ... Okay, so (some time later) I've gotten it to compile. It kept giving me problems with:

there was nothing about this online. Doomed. ug. So, I peeked in the zmq/utils/zmq_compat.h file to see what it was objecting over. The lines were freaking comments. For some unknown inane stupid reason, the IBM cc (c compiler) objected to perfectly valid comment lines "// new in 3.3.0". So, I know how to edit out comment lines!!! I backed up the file and removed them. Success compiling! I see lots of copies to the prefix directory!
Now, to test: invoke python, import zmq...:

Compiling Python with Bz2
Building python from source on RHEL5, I've had some troubles. Python keeps not finding bz2, giving me the complaint:
Python build finished, but the necessary bits to build these modules were not found: _tkinter bsddb185 dl gdbm imageop sunaudiodev To find the necessary bits, look in setup.py in detect_modules() for the module's name. Failed to build these modules: _curses _curses_panel _bz2
I already BUILT bz2 and installed it with the right prefix. UG.
FINALLY I found the following hint. Turns out bz2 source compile / make doesn't make everything by default. It just makes the executables bzunzip2, etc., but not the all-important (to python compiling) libbz2_so.
There's a file there, though, you just have to invoke it!
$ cd ~/temp $ wget http://www.bzip.org/1.0.5/bzip2-1.0.5.tar.gz $ tar zxvf bzip2-1.0.5.tar.gz $ cd bzip2-1.0.5next, TWO MAKES. INVOKE BOTH MAKEFILES:
$ make -f Makefile-libbz2_so $ makethen, it works. NOTE: for the rest of the instructions, I like the page: http://rajaseelan.com/2012/01/28/installing-python-2-dot-7-2-on-centos-5-dot-2/
