Stepping in it

I’m not blogging about politics because the wind changed direction—waiting finally beats getting worked up.

This sarcastic post from Balloon Juice though has a novel summary of what is going on with the Attorney General firings and how it occurred. This is just a fascinating piece of political good-on-paper-bad-in-practice maneuvering on the part of the Republican Party, as well as great political detective work on the part of Talking Points Memo.

Facebook @ SXSW

When did SXSW become the “It” conference? I remember when people in the Valley would say “I have to go to SXSW” followed by a sigh that reminded me of how I used to approach mowing the lawn.

First comes the music, then comes the money, then come the geeks? Or is this another excuse for LA to jet to TX for some real BBQ?

In any case, if you are there, you might want to attend the the Facebook party tonight. Apparently, like an acquaintance’s Burning Man tent, there’s going to be Red Bull on the house.

Be sure to register now to get the super secret location sent back to you. If you are bored and sober, ask the Facebook people what’s up with the FQL thing—all my mad, non-existant SQL skills transferred to an API? Or, why salt every request in the session with a ref counter provided on client side?

Be sure to get them good and drunk before doing so. The answers might be halfway interesting then. 😀

fo shizzle

In an e-mail recently someone used the phrase “fo’ shizzle.”

Now having worked at Plaxo I’ve heard the term and seen it used when we play Counterstrike and such, and it’s used on television more, but I never saw it written out. For some reason print or e-mail is different than chat or IM. I have a distinct recollection of when “da bomb” (1994) or “so ghetto” (1998) reached that point, followed by a quick musing of where the hell the term came from—I mean besides the obvious answer in this case: Snoop Dog.

Urban Dictionary provided it to me:

“fo shizzle ma nizzle” is a bastardization of “fo’ sheezy mah neezy” which is a bastardization of “for sure mah nigga” which is a bastdardization of “I concur with you whole heartedly my African american brother”

I love the internet.

The Shu Ha Ri of strings

In a discussion on the speed differences between various types of strings, I was completely misunderstood (or ignored).

Sad.

George told me his all-time favorite PHP talk of mine was the first one I gave: “OOPs: The PHP Fear and Loathing Guide to Basic Object-Oriented Design.” Perhaps one reason may be is this segment (click the image below a bunch to playback the slide deck):

Shu-Ha-Ri is the way you learn in Aikido, but it applies to everything. For those who didn’t play back the above slidedeck or understand it, here is the ideas I want you go have in your head:

  1. Shu – Hold – Copy
  2. Ha – Break – Deconstruct
  3. Ri – Leave – Transcend

Shu: Use the single quote

Here is a summary of results a PHP developer who leads the unexamined life:

  • Single quotes are always faster than double quotes but the difference is negligible.
  • Function parameterization is faster than concatenation (use commas over periods when calling print or echo).
  • String concatenation is always faster string interpolation.

But this can be understood with a simple Ri maxim:

“In PHP, always code for readability first.”
—Me circa 2004

I’ll explain how to get from Shu to Ri in gory detail below and answer a couple of my favorite interview questions in the process.

Sensing a great disturbance in the force

…of my 2008 budget.

“Depth of field” huh?

Pentax 645D prototype (200609-06)Pentax 645D prototype rear (200609-08)

A Pentax medium format digital camera. 19 or 31 megapixel CCD sensor with 1.4x crop factor in 645 format (44mmx33mm). Basically that’s twice the image area of 35mm “full frame” or .7x “crop factor” 35mm equivalent. Just saying this just shows the total futility of thinking in crop factors. Both use an offset microlens technology that first saw light of day in the Leica M8 to deal with vignetting.

Price (estimated): $7-12k. It’s Pentax so you know it’ll be much cheaper than that the Hasselblad H3D (48mm 39mp $32k, 48mm 22mp $27k and 44mm 31mp $25k), and the Mamiya ZD (48mm 22mp, $12k est.). On the other end you have the Canon EOS-1Ds Mark II (36mm, 17mp, $7.4k). Another reference point is film 645 format cameras are around $3k.

Also known are multi-channel readout, SDHC and CF media support (I hope they’re using UDMA instead of PIO). 1/4000s max shutter speed in a leaf shutter. Probably a max ISO around 800. The usual suspects: AE and AF lock buttons, bulb, MLO, cable releases, flash sync. Burst speed and buffer is unknown (a fast camera in medium format digital is is 1 shot in 1.5 seconds).

While we are dreaming wishlist: Pentax sensor-shift-based shake reduction in a medium format digital. I’d open my wallet this year if it had it. Seriously.
