I guess we're at a different phase of the Zap2IT guide data thing now. The story has broken, there's been tons of email on the mythtv-users mailing list (remember, don't panic!), and now things have quietened down. I think that's probably a good thing, because it almost certainly means people are now no longer distracted from actually sitting down and working on the problem. I imagine that journalists would make up some sensational thing to say to keep the story rolling during this quiet news cycle. I can't think of any such thing to say, and it wouldn't be ethical anyway. I must say that I think coverage like this isn't always helpful.

Some quick further thoughts on the Zap2IT shutdown

  • Post author:
  • Post category:Mythtv

The Zap2IT forums has a thread about the shutdown (you need to have a Zap2IT login to get to the forum). One of the posts on the thread about the shutdown expands on the reasons for the free guide data shutting down: - Continued use of the service to support commercial products, in violation of the agreement. - Commercial products continued to grow despite previous appeals that this activity stop. - There are significant changes to the supporting data structure forthcoming and we could not devote resources to the continued upkeep and enhancements of the service. - Maintenance of the service is impacting our resource pool for other projects. - We sought alternative options but were unable to find a solution. - We recognize the hardship this creates for the user community. We are open to alternative solutions and would consider proposals that met the needs of the user community and our company. - We looked into options to turn this into a paid service however we do not have the infrastructure at this time. So it seems that the folks selling MythTV based solutions which used the guide data, as well as possible other commercial uses (the was no…

An initial analysis of the removal of Zap2IT guide data in the US

  • Post author:
  • Post category:Mythtv

(I had some spare time while waiting for the kids to finish their breakfast, so this is posted earlier than I planned). As mentioned briefly earlier today MythTVnews.com is reporting that Tribune Media Services (TMS) is turning off their free guide data service for MythTV on 1 September 2007. This is mainly because of claims of abuse -- the theory on the MythTV users mailing list is that this abuse is vendors selling pre-configured MythTV systems for profit, which use the not-for-commercial-use guide data service from Zap2IT. The announcement from TMS reads: IMPORTANT MESSAGE: For several years we have offered a free TV listings service to hobbyists for their own personal, noncommercial use. In October of 2004 we posted here an open letter saying the future of Zap2it Labs was at risk because of certain growing misuses of the Zap2it Labs data. Unfortunately this misuse has continued and grown. These misuses, combined with other business factors have led to the decision to discontinue Zap2it Labs effective September 1, 2007. We thank those users who have honoured the terms of the agreement, and we suggest you consider the many TV listings options offered by the commercial licensees of TMS TV listings…

Breaking: Zap2IT turning off guide data for the US?

  • Post author:
  • Post category:Mythtv

MythTVnews.com is reporting that Tribune Media Services (TMS), the providers of the Zap2IT guide data used by MythTV in the US, will turn that guide data off on 1 September 2007. I haven't had a lot of time to look into this further, mainly because I am giving a talk this morning. I'll have a better look at lunch time (PDT) and write some more about this. I think there's no need for panic, as a new guide data source will be found, but this is unexpected.

Implementing parental filters with MythTV

  • Post author:
  • Post category:Mythtv

The other morning I walked out to my five year old watching Robot Chicken. This isn't what I would call the highlight of my parenting career, but it did leave me with an immediate need to come up with a solution to stopping the kids from watching inappropriate things now that they're big enough to work their way through the MythTV user interface without our assistance. Its now quite common for me to wake up in the morning and discover that the kids have turned the monitor on in the living room, have found one of their shows, and are happily watching. (I guess it says something about the ease of use of the MythTV user interface that my four and five year olds have no trouble navigating it without assistance. Specifically, the video thumbnail of the various recordings is a killer feature because it helps kids who can't read yet find the shows they want.) The animated thumbnail of the recording appears in the bottom right of this example image. Back to my need to filter recordings. Unfortunately this isn't covered in the MythTV book (Amazon), mainly because it didn't seem to me to be a killer feature at…

How to transcode video for the Nokia N800

  • Post category:Mythtv

I have a Nokia N800 that I haven't had much time to play with, but I am about to go away on a trip which will involve a lot of time commuting on buses, so I figure I should start thinking about it again. Luckily for me, this page has pretty good instructions of what settings to use with mencoder to make it all look good on the N800. I haven't tried them yet, but I will report back when I do.

Building a symlink tree for MythTV recordings

I wanted to build a directory of symlinks that pointed to my MythTV recordings, so I wrote a little python script to do it for me. I figure someone else might find this useful too... #!/usr/bin/python # Copyright (C) Michael Still (mikal@stillhq.com) 2007 # Released under the terms of the GNU GPL import MySQLdb import os import re from socket import gethostname # Connect to the MythTV database based on the MythTV config config_values = {} home = os.environ.get('HOME') config = open(home + '/.mythtv/mysql.txt') for line in config.readlines(): if not line.startswith('#') and len(line) > 5: (key, value) = line.rstrip('\n').split('=') config_values[key] = value db_connection = MySQLdb.connect(host = config_values['DBHostName'], user = config_values['DBUserName'], passwd = config_values['DBPassword'], db = config_values['DBName']) cursor = db_connection.cursor(MySQLdb.cursors.DictCursor) # Regexp for what is allowed in the symlink name unsafe = re.compile('[^a-zA-Z0-9\-\:_]+') # Find the recordings directory -- this assumes you haven't used an # identifier string for this machine... cursor.execute('select * from settings where value="RecordFilePrefix" and ' 'hostname="%s";' % gethostname()) row = cursor.fetchone() basedir = row['data'] # Now find all the recordings we have at the moment cursor.execute('select title, subtitle, starttime, basename from recorded;') for i in range(cursor.rowcount): row = cursor.fetchone() title = row['title'] subtitle = row['subtitle'] if subtitle…

How do you spot the Australian kids in an American playground?

  • Post author:
  • Post category:Travel

They're the ones wearing hats. Despite it being noon, the various American kids at the playground all lacked sun protection. In fact, they pretty much all lacked practical clothing, it was all way too dressy. Americans don't seem to have figured out skin cancer at all in fact, every weekend there are bikini clad young ladies sunning themselves around the pool, the schools don't require kids to wear sun protection, and it's pretty common to see outside workers not wearing any sun protection either. How odd.

"If you're interested in setting up a PVR, then this is definitely a book to check out. Apress sells the paper version for $30, and offers an eBook for $15. Amazon offers it for $19.79, but I doubt that price will last long. I definitely give this book a 5 out of 5..." http://www.yeraze.com/article.php/20070603160650701

Is there any way to access the match text in MySQL rlike selects?

  • Post author:
  • Post category:Mysql

Hi. I am doing a select like this in MySQL 5: select * from foo where bar rlike '(.*),(.*)'; The specific example here is made up. Anyway, I'd like to be able to get to the matched text from bar, like I can with various languages regexp libraries. Is this functionality exposed at all in MySQL? I've looked at the docs and can't see any indication that it is, so this might just be wishful thinking.
