new!

June 24, 2007

When I set up this blog, I bought the pseudosemantics domain, I just didn’t have time to get the site set up.  Up until now I have been taking advantage of the hospitality of the wordpress to host my site.

 Now I finally have my blog set up on my own domain, with a different theme (couldnt’ find this one again) Look for further updates on http://pseudosemantics.com 

 Thanks.

If you are dead, You should have gone to the doctor

June 18, 2007

My wife is 9 months pregnant, and she had a rough weekend, her stomach has been hurting her, and she had odd irregular contractions.  So she got online to look up some information about false labor.  One of the sites had a caveat to the effect “True labor ends with childbirth.  Therefore once you have had your baby you can be sure that you were in true labor.”

 Using the same logic, here’s how to know when to seek emergency care.

  • If you bleed to death, the cut needs stitches
  • If a broken bone heals crooked, you should go in and have it set.
  • If you heart stops beating, the pain in your chest was a heart attack.

Just in case you were wondering.

Life is not random

April 14, 2007

I don’t care what they tell you.  Life is not random. 

Life bunches up on you.   It will come at you in patches and bursts.  You’ll spring for pizza on a thursday night, then someone will bring pizza to work on Friday, and you’ll visit your parents on Saturday, who will offer you some pizza.

Next, a three week pizza drought.

When was the last time you had alternating good and bad days?  –doesn’t happen.  You have a few good days, then a rut that lasts a week.

Why do you think they call it a lucky streak?  If it was totally random, everyone would win and lose equally.  (at least with games of chance)

Your Next TV–Component vs HDMI

April 5, 2007

The obvious choice is that you will run whatever connectors you have.  You can’t easily convert one to the other.   But, if you have a choice here are some guidelines. 

Over short runs in your entertainment center, you probably will not be able to see much of a difference (at least I can’t) Both are high definition connections, capable of 480i, 480p, 720p, 1080i, or 1080p. HDMI however is much cleaner, sending HD video and audio over a single cable with a USB sized connector.  Component uses three video connectors for video only, and audio is run separately as stereo (red and white RCA) or surround sound audio with a digital coaxial or toslink connection.

For the boring details about the differences, keep reading… 

This goes back to the digital VS analog battle.  Component is analog, and HDMI is digital. 

Since most devices process HD video as a digital signal, HDMI doesn’t need to convert to analog and back for the cable.  Any digital to analog conversion will introduce some loss, so this can maintain a better quality.

Second, besides sending an amazing video signal, it can also send up to 8 channels of digital audio (perfect for a 7.1 surround sound)–All that over a single, small connector. 

HDCPis supported on all HDMI connections, which can be a blessing and a curse.  HDCP is technically a content protectionmeasure.  It will check that every frame sent is a perfect signal transfer, ensuring that there is no loss over the cables, connectors, or interface.  However, in order to get an HDCP license, the product has to meet some copy protectionrequirements.   For most situations, it won’t interfere, but it can have its drawbacks–for instance HDMI and DVI-D use identical video signals (DVI doesn’t support audio)(And yet, the connector is like 4 times the size)  So you should be able to connect an HDMI source to say a digital widescreen monitor, but many DVI displays don’t support HDCP, so it will not play copy protected content.  Some legitimate video splitting or switching functions are disabled as well.

The HDMI specification states that a repeater is required for cable runs over 15 feet.  In practice I haven’t seen that always necessary.  HDMI was originally designed to run longer distances (45 feet) but was changed just before release.  Under 50 feet, there is rarely need for a booster, especially if you are using a high quality cable.  However if you are pushing a high resolution, (Like 1080p) you might notice some sparkling.  You can get an HDMI booster, which will clean up any sparkling or loss you might find.

Component doesn’t necessarily have it’s own features, but it doesn’t have some of the drawbacks of HDMI.  (I guess it does have some drawbacks of its own)

Since component is an analog signal, it handles long distances much better.  Over long or low quality cables, there might be some loss, but it will generally just be a slight loss of clarity or signal intensity, often unnoticeable.

Component video doesn’t support/require HDCP.  You can run full HD content without restrictions (Assuming your source will feed it to you)

Who thought that up?

April 4, 2007

 We had a conversation at work about some things that are cool, but don’t know how anyone figured it out.

An example I saw demonstrated by an old roommate, Riley:

  1. Take a heavy glass tumbler, and flip it upside down (it’s recommended that you start with an empty glass, but at this point it doesn’t really matter)
  2. Using a cigarette lighter, heat one of the edges of the tumbler
  3. Turn the tumbler on it’s side and press the hot edge against a table or counter top until it cracks.  (just a crack)
  4. Turn the glass upright and place it on the table/counter.
  5. Wait.

The glass will spontaneously shatter.  I saw it twice.  Once, a chunk of the glass just hopped out of the tumbler, a little surprising, but not really impressive.   Riley wasn’t satisfied, so he repeated steps 1-5.  The glass exploded!  The entire glass shattered and shards slid across the counter-top and onto the floor.  It was really cool.

But I was left wondering, how did he figure that out?  What got it into his head?  How many glasses did it take to perfect the process?  How did he think that up?

Jonathan learned a trick to make a sparkling explosion with a couple of lighters–you’ll have to get the details from him.  But similar questions arose in his head.

The one that always got me… was bread.

Who thought that up.  I can’t imagine the process.  “Let’s see.  This really tall weed has a little chewable seed wrapped in some skin stuff.  Let’s not eat it now, but lets gather up all the little seeds, throw away the rest of the plant, and keep the seeds for a while.”

“Now the seeds are hard, lets see if we can grind them into a powder, but don’t eat it yet, lets mix in some water and make a sticky paste.  Hmm, I still don’t think it’s ready to eat”

“Maybe throw in an egg, or some little bacteria that will make the paste bloat and expand… yeah, that might be good… now let’s stick it in the fire…and….BREAD!”

I was baffled at how the breadmaking process could have ever been conjured up… then I realized–it wasn’t guessed, it was taught.

Bread was a gimme when Adam was kicked out of the garden “In the sweat of thy face shalt thou eat bread, till thou return unto the ground;” (Genesis 3:19)

So the conversation was more:

“Sorry, you can’t stay here anymore, but I found something cool you can do with that weed…”

Humans: Born compassionate

March 11, 2007

(I couldn’t think of a good antonym for manipulator)

So, maybe I was a little too quick to pull out my cynical side.   

It had been a long week, and when I got home from work yesterday, I just sprawled out on the couch.  I was lying there with my eyes closed, not yet asleep, and my daughter toddled around the couch. 

“Kai kwi, be kwi” (translation: Be quiet) in her little whisper voice.  She leaned in and gave me a kiss, then wandered away again.  A minute or two later, she came back, said the same thing, gave me another kiss, then shoved a teddy bear under my neck.  She likes to sleep with  a teddy bear or a doll, and so I’m sure she wanted to help me go to sleep too.

 You hear, and expect, that children that young are pretty self centered–just that they only think of their needs.  But she obviously cares for me, and was trying to do something to make my life better.

I’m impressed.

Humans–Born manipulators

March 6, 2007

I have a 16 month old daughter Julia.  She doesn’t like to go to bed.  The other night, my wife Emily was trying to put her to bed.  We have tried to teach Julia a little baby sign language, and it has really helped her to communicate early with us, so you get a window into the mind of a pre-toddler.

 On her way to bed, Julia signed for shoes.  She tapped her little fists together and said “shoo, shoo.”  (My daughter isn’t a year and a half old and she has a shoe fetish)  Emily looked to see if there were shoes in view, or maybe in the bed… “No, you don’t need any shoes, it’s time for bed”  A moment later Julia brought her hand to her mouth “Fooh, fooh.” 

“No, you don’t need any food, you just need to go to bed.”

“Gawh-djee, Gawh-djee.”  With her finger tapping her lips.  (That is how Julia says, and signs, water)

 ”No, you just need to go to sleep”

Julia lied there thinking for a moment….

“Shour, Shour!”  Her little hand was pumping the air like a shower head.  Emily couldn’t help but laugh.

 She was puling out every excuse she could think of to try to get out of bed!  It’s so funny that at that age she will try all of that.

…………………………………………………………………………………………………………………..

She will usually go to sleep for me pretty well.  She doesn’t try all those tricks on me–I guess I’m just not sympathetic enough.  Tonight I was putting her to bed and she was having a really hard time.  She was tired, she could barely keep her eyes open, but she would just lie there barely awake.  After 20 minutes of trying to sneak out quietly, I finally decided to just leave.  Sometimes she will cry for a moment, then fall asleep–but, not this time.  I went back in after a few minutes, and still couldn’t get her calm.  Finally the cavalry came in.  Emily came in after me and took over.  Julia was more than willing to go to Mom. (For some reason, dad’s just aren’t as good) 

As I left the room, I heard Julia saying “Fooh, fooh”

Pseudo Semantics

February 27, 2007

I used to think that blogs were the worst things to happen to the internet.  (but I think I started with a bad sampling) I thought that it took the concept of a forum–open, moderated discussion for the masses–and stripped out all the good.  Allowing anyone with a keyboard to print their rants as doctrine, and only allowing the comments/opinions they accepted. 

I later realized that some people actually have something worth reading about in their heads.   And for the rest of us…if you care about the person, you enjoy finding out what they write/rant about when no one is interrupting or dismissing their ideas.  It’s actually quite enlightening.

This is admittedly a jump-on-the-bandwagon blog.  And everyting here is a little tongue in cheek.  Not that the content is fake, I won’t try to convince you I am something I’m not…but on the other hand I won’t likely show who I really am either.

 So if you are looking for meaning, this is not the place, but if you don’t mind a little superficiality, then maybe you should poke around for a while.
