There are two powerful tendencies in the course of software development. One is to construct ways to control something and thereby tune performance. Class based queuing and discriminating by firewall marks are excellent examples of this. Another is to throw out what you have -- and anything that might interfere -- and implement everything from your application down to the hardware. Databases and zero copy implementations are good examples of this.

Both of these conflict with maintainability and generalization by making things more complex. This is something which I've designed Ultimate OS to avoid by modularity.

Thanksgiving dinner came on Friday at a place in Berkeley -- a very fine meal with relsqui and her parents was had. In addition, we had Mongolian BBQ at our favorite local place with stonesundial, zigdon, gemlikeflame, and M-. Amusingly, I ran into my friend R- there -- I've seen him three times and I have his card and I've promised to email him and get lunch with him sometime. This has been frustrated by various factors. This time, he took my number and email. Hopefully, we'll get things hammered out there.

Afterwards, a couple of us went back to zigdon's. I played Portal for a bit and for the first time. I think I'm going to have to subject some of my hardware to Windows -- it was awfully fun.

I've been hanging out in #koalawallop on irc.holonet.net. Many good folk there, including the author of the very fine comic Dresden Codak. By way of introduction, I suggest Traversing the Luminiferous Aether and After Many a Summer Dies the Swan.

(Also, exchanges like this are unexpected and awfully nice ego boosts:
17:10 < root> But I think my next TV isn't going to be a TV.
17:10 < root> it's going to be a projector
17:10 < Jacen> That's the best way to go if you can afford it.
17:10 < root> and additionally, I'll use a TV capture card in a computer to 
              drive it.
17:11 < zoanne> root: are you professionally cool or what?
17:11 < armrha> which projector are you going for root?
17:11 < zoanne> because you do so seem to be insanely fabulous
)

Tomorrow's another day of work. I'll likely be frustrated somewhat by meetings tomorrow, but hopefully I'll get useful stuff done.

Hopefully, you've all had a productive and restful weekend. I have a few topics kicking around waiting for a more substantial time to post.

Well, let me tell you that a projector replaced my TV about 2 years ago. :-D

I've been planning on it for some time, but there's been three factors which have held me back.

The first of which is the cost and lifespan of a projector bulb. Given my fiancee's habit of using my computer while I'm not at work, it's reasonable to assume that the projector's live for a full half of a day.

(also, that'll drastically improve the quality of my nethack games 8) )

The second thing is that there's still a lot of variance on which technology's going to prove the most viable. It seems to me that DLP has a real shot at it, but the rainbow effect's a real annoyance. If LCOS didn't amplify my first concern and had a reasonable price associated with it, it'd be the clear choice. Alas!

The third bit is that I haven't quite decided where I'm going to project. I have a pretty extensive game console collection and my predilection for things like Duck Hunt make keeping an old CRT around a necessity.

Anyway, my bitching's out of the way and I'm really quite curious what your setup is and how that's working for you. Maybe the time to make the jump is nearer than I thought. 8)

Yeah, I had the same thoughts you are having. The technology question was answered rather easy. DLP was too expensive 2 years ago (for me). I bought the Sanyo PLV Z4, which was a pretty well tested and especially quiet (important!) HD ready LCD projector, but still affordable to me. Also neither me nor my girlfriend really spent much time on watching TV, so the projector was there for DVD mostly. That said.. I'm still using my first light bulb although I've unnecessarily bought a second bulb a little while ago.

I set it up in my living room, projecting onto a wall I had intentionally left blank ;) opposite to my sofa. I already had a surround sound system set up, so all I really was missing, was a large screen. I'm not using any other screen than the wall paper, which is a minor set back in quality, but it allows to have a huge projection (2,50m wide) which I don't want to miss. I've tried to use a good but smaller screen, the theater feeling just wouldn't arise.

The playstation 3 hit the German market two days before my birthday this year. That was an omen – I had to get one. ;)

So nowadays I enjoy the good up-scaler of the PS3 to watch DVDs and from time to time I spend the money to afford a Blu-ray disk, which look awesome but are incredibly expensive. Also I enjoy playing Motorstorm and stream music from my server onto the PS3.

After all I must conclude. I couldn't imagine using a tv for watching movies anymore, no matter how large. The huge projection really is an experience not to be traded in for anything.

A friend of mine, btw., bought a Panasonic DLP projector a few weeks ago. I haven't seen it yet, but supposedly it's really good. From what I've heard, the rainbow effect is only noticeable to a few people, so you should check that out for yourself. Today I'd favor DLP for the better contrast. The LCD's projection of black is actually rather grey and annoying from time to time if you watch a movie with a lot of dark sequences in it.

I wouldn't use a projector to watch lots of TV or to use it multiple ours per day for whatever, but other than that I'd say, GET ONE! :) If you're interested I could find out more about the Panasonic model my friend got, that's probably a good one to consider.
