TV converter box

Looked at consumer reports and decided to get the Insignia NS-DXA1 which is the same as the Zenith DTT900. Some reports say that there is an audio problem, and some guys actually did an fft of the signal output and showed that there are mysterious peaks at 12kHz and 16kHz. I'll be able to tell later tonight if this is gonna be a problem. Isn't it convenient that this simple piece of electronics is prices around $60? Which comes to $20 after our pooled tax money supplies $40? I think the guys at the company decided that people would be willing to pay $20 for this thing, and hence the price.

UPDATE: One trick for the sound apparently to bump up your TV volume all the way and use the Insignia to control the volume. [here] See my experience below

UPDATE: The box works well
  1. I got 22 channels. This depends on antenna positioning. With another position I got 19
  2. The signal is really really clear. We used to get grain all the time with analog
  3. Sound doesn't have a hiss problem. I boost the converter volume to 100% and adjust the TV volume.
  4. The hiss problem goes away when audio is set to Mono.

A note on Python's __exit__() and errors

Python's context managers are a very neat way of handling code that needs a teardown once you are done. Python objects have do have a destructor method ( __del__ ) called right before the last instance of the object is about to be destroyed. You can do a teardown there. However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or...

Store numpy arrays in sqlite

Use numpy.getbuffer (or sqlite3.Binary ) in combination with numpy.frombuffer to lug numpy data in and out of the sqlite3 database: import sqlite3, numpy r1d = numpy.random.randn(10) con = sqlite3.connect(':memory:') con.execute("CREATE TABLE eye(id INTEGER PRIMARY KEY, desc TEXT, data BLOB)") con.execute("INSERT INTO eye(desc,data) VALUES(?,?)", ("1d", sqlite3.Binary(r1d))) con.execute("INSERT INTO eye(desc,data) VALUES(?,?)", ("1d", numpy.getbuffer(r1d))) res = con.execute("SELECT * FROM eye").fetchall() con.close() #res -> #[(1, u'1d', <read-write buffer ptr 0x10371b220, size 80 at 0x10371b1e0>), # (2, u'1d', <read-write buffer ptr 0x10371b190, size 80 at 0x10371b150>)] print r1d - numpy.frombuffer(res[0][2]) #->[ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] print r1d - numpy.frombuffer(res[1][2]) #->[ 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.] Note that for work where data ty...
