The State of Household Robots

Van Halen Re:I have a household robot (102 comments)

We have 3 dogs and 1 cat. The two smaller dogs and the cat don't shed much, but the larger dog (a lab) sheds like crazy. We have 2 Roombas that we got about 3 years ago when the 500 series started coming out. We no longer use them regularly because it's too much of a hassle.

First, they need to be cleaned at least daily with this much pet hair. Cleaning takes at least 5 minutes; if I just spent that time vacuuming normally for 5 minutes a day, the floors would be cleaner.

Often they won't even complete a single run without stopping and saying "Please remove and clean Roomba's brushes." That kind of defeats the purpose of having cleanings scheduled during the day (when we're at work) if it only gets 15 minutes into the scheduled 45-minute cleaning before stopping.

The Roombas will leave "Roombarf" - tufts of pet hair - on the floor when moving from hardwood/tile to carpet. Apparently the vacuum isn't powerful enough to suck all that stuff into the dustbin, so it just drags the hair along until the terrain change knocks it loose.

Every few weeks, we'd need to take the thing apart and do a really deep cleaning, as pet hair got everywhere inside. This would be a 30-60 minute job. One nice thing is that iRobot designed the Roomba to be very modular, so taking it apart isn't too bad.

One of the Roombas is completely out of commission right now because it has a faulty bump sensor. It thinks it's constantly bumping something, so it just spins around in circles trying to get free. I found a great web page somewhere (sorry, don't have the link handy) about fixing this with just a few bucks in electronics parts. I'll probably do it just for the fun of it, but that won't fix all of the above issues.

iRobot has a pet version of the Roomba which came out after we got ours, but from what I can tell, all they did was include a second interchangeable dustbin without the vacuum module that therefore has larger capacity. The normal dustbin combines the vacuum into one integrated part. I can't imagine this larger sweeper dustbin would do anything to pull the pet hair in without the vacuum to help.

For a household like ours, I would like to see a Roomba that's about a full inch taller, giving it room for a larger battery, larger dustbin, and more powerful vacuum and brushes. An added bonus for us is that since a couple of our couches are just the right height for the current Roomba to get under and then get stuck, a larger one wouldn't even go there at all.

I wholeheartedly recommend Roomba for a household without pets (or with very little shedding), but can't really recommend it with pets that shed a lot. Unless you have all hard flooring - it seems to do a lot better with the pet hair there.

Best PC DVR Software, For Any Platform?

Van Halen Re:TiVo for the win? (536 comments)

The key to using pyTiVo with DVD rips is to simply extract the original MPEG-2 stream from the DVD without transcoding at all. pyTiVo will then send it to the TiVo (at least TiVo HD, probably Series 3 as well) as-is, and the result is exactly what you'd see (and hear) if you had popped the DVD into a DVD player.

On the Mac, I use RipIt to rip the DVD, followed by DVDRemasterPro to extract the main title as a single vob. Often this is enough, and the vob will transfer and play directly on the TiVo. Sometimes a pass through MPEGStreamClip is also necessary to clean up timestamps.

MacTheRipper is sometimes good on old titles that don't have all the new fair-use prevention measures - it can extract a single title from a DVD in a single step instead of the multi-step process above. But it doesn't handle about 90% of newer DVDs.

This works on probably 95% of the DVDs I've tried. Of the remaining handful, a manual pass through ffmpeg (using the "copy" pseudo-codecs) fixed a couple, but a few still are problematic for the TiVo's MPEG-2 decoder.

Stupid Mac Fanboy (31671) writes "Apple just announced that Leopard will be delayed until October. They cite the development of the iPhone as the primary reason:

iPhone contains the most sophisticated software ever shipped on a mobile device, and finishing it on time has not come without a price — we had to borrow some key software engineering and QA resources from our Mac OS X team, and as a result we will not be able to release Leopard at our Worldwide Developers Conference in early June as planned. While Leopard's features will be complete by then, we cannot deliver the quality release that we and our customers expect from us.
According to the release, developers will be given a "near-final" beta copy of Leopard at WWDC in June."

Angry music lover (31671) writes "It's about 5 years overdue, but the new versions of iTunes and iPod announced today finally support gapless playback. Other iPod highlights include longer battery life, 80 GB storage, new games, and a new search interface. iTunes 7 also adds movie downloads (currently 75 movies available from Disney-owned studios) at 640x480, album cover view, downloads of album art from iTMS, multiple libraries, iPod summary, and others. Apple also posted the MPEG-4 stream of today's event, available here."
