Radiation Dose and Effect: Visual Perspective

Filed in ScienceTags: Media Bias, Radiation

If you're worried about radiation dose and health effects in the wake of the hurricane- and tsunami-induced damage to the Japanese nuclear power plants, then I would highly recommend that you take a look at this Radiation Infographic. 1

Incorporating the Settings API in WordPress Themes

Filed in Web DevelopmentTags: Settings API, Themes, tutorials, WordPress

The inter-tubes are awash in tutorials for how to add Theme Options to WordPress Themes - so why write another? Primarily, because most such tutorials are several years old, don't implement current best-practices, and were written without any awareness of the WordPress Settings API.

While others such as Otto and Ozh have done yeomen's work in explaining how to implement the Settings API, I have not yet come across anything that really put everything together, and explained the process and implementation from beginning to end, in a way that even the less-experienced Theme developers (like me) could easily understand.

This tutorial will attempt to fill that gap, by providing examples of current (as of the pending release of WordPress 3.1) best-practice implementation, not merely of the Settings API, but of Theme Options implementation as a whole, including:

  • Registering options in the database as a single options array
  • Initializing default options
  • Creating a single Theme Settings page (with tabs)
  • Defining settings page sections and fields
  • Validating and white-listing user-input form data
  • Adding Settings Page contextual help
  • Enqueueing custom CSS for the Settings page
  • Implementing settings in the Theme template files
  • Enqueueing front-end CSS

Throughout this tutorial, I will be using code from my Oenology Theme for implementation examples. For full code, see the latest development version.

Assumptions: Best Practices

The following will be the working list of best practices that will be incorporated:

  • Theme Settings defined as an options array in a single database entry
  • Theme settings added to a single Theme Settings Page
  • Theme Settings page is added to the "Appearance" menu
  • Theme Settings page added using the "edit_theme_options" user capability
  • Theme Settings registered, updated, and validated using the WordPress Settings API
  • Theme Settings modify the template using action/filter hooks wherever possible

Getting Started

The first thing we need to do, even before touching any code, is to determine:

  • What options to include in the Theme
  • How to organize those options on the Theme Settings Page

In my case, I am adding only a handful of simple options:

  • Header Navigation Menu Position: currently, Oenology displays the Header Navigation Menu above the site title and description. I am adding a setting optionally to display the Header Navigation Menu below the site title and description.
  • Header Navigation Menu Depth: currently, Oenology is designed so that only the top-level Pages display in the Header Navigation Menu, and Child Pages display in a left-column sub-menu. I am adding a setting optionally to display Pages to a depth of one (top-level Pages only), two, or three, with hover drop-down menus.
  • Footer Credit Link: currently, Oenology does not display any form of footer credit link. I am adding a setting optionally to display a footer credit link.
  • Varietals: the default style of Oenology is intentionally minimal. It is intended to be clean, simple, and cross-browser. I am adding a setting optionally to select from among Theme "skins" (which, in keeping with the oenology metaphor, will be called "varietals"), which will apply different color/style schemes to the Theme.

Given that I'm only adding four Theme options, I could very easily put all four together on one Settings page. However, I may want to add additional options in the future - and also, I want to provide a proof-of-concept for creating complex Theme Settings pages in a way that supports the Settings API. So, the Theme Settings page will have two tabs: "General", and "Varietals". Further, the "General" tab will have two sections: "Header Options" and "Footer Options".

So, that's our basis. Let's get started!

Rutabaga: Well-Kept Low-Carb Secret

Filed in PersonalTags: Health/Nutrition, Low Carb

Oh, rutabaga, where have you been my whole (low-carb) life?

I have been a dedicated low-carber for over a decade. While I could go the rest of my life without eating another dessert or drinking another soft drink, my meat-and-potatoes farm-community up-bringing often leaves me missing starch-laden foods of my youth, such as fried potatoes and biscuits and gravy. In fact, when I decide to splurge, it is almost alway with one of these two foods. In over ten years of living low-carb, I had never found a suitable, low-carb replacement for crispy potatoes fried in bacon grease.

Enter the rutabaga: humble root vegetable, that also happens to be incredibly low in carbohydrate (under half the net carbohydrate content of a potato). While not a strictly low-carb food, it makes for a great option for the occasional potato fix.

Apparently, the rutabaga has fallen out of popular use, due to its reputation as famine food during World War II. How unfortunate. As it turns out, the rutabaga is basically just as easy to work with as the potato, and makes an equally good accompaniment as the potato when fried.

Here are the results of tonight's experiment with making fried rutabaga.

The rutabaga is at first a somewhat unusual-looking vegetable, but is actually easier to peel than a potato:

Rutabaga Peeled and Unpeeled

Once peeled, rutabaga is considerably more difficult to cut through than a potato; however, once I quartered the rutabaga, the mandolin made quick work of slicing:

Rutabaga Quartered and Mandolin-Sliced

I initially fried a small batch (1/2 rutabaga) of potato chip-thin slices, to get a feel for the texture and taste of fried rutabaga.

Frying a trial batch of rutabaga

Having discovered that rutabaga fries essentially the same as potato, we were pleasantly surprised further to discover the mild, natural sweetness of rutabaga that - especially when crispy-fried - pairs in a rather addictive manner with a little salt and pepper.

Finding the trial run successful, I set the mandolin to one setting thicker, sliced another whole rutabaga, and fried the whole batch in bacon grease, as before.

This batch definitely took longer to cook than the potato chip-thin slices, but still barely took longer than the time required to broil pork chops.

The pork chops and fried rutabaga (garnished with a few bits of crumbled bacon), combined with some Brussels sprouts "slaw" (steamed Brussels sprouts, core removed, mashed/quick chopped, with butter, Parmesan cheese, and a few drops of lemon juice) made for a tasty and - and unexpectedly filling - meal.

(I actually was unable to finish the entire plate.)

Next up: rutabaga chips in the deep fryer, rutabaga soup (using my secret family potato soup recipe), and roast with rutabaga.

  • @prossorguk knew I forgot something! Going in to fix... in reply to prossorguk #
  • @prossorguk fixed! in reply to prossorguk #
  • I totally called (albeit one play early) that Rodgers naked bootleg! Nice opening drive by the Packers there. #
  • A PUNT from the 34-freaking yard line?!? Is Lovie Smith channeling his inner Jim Caldwell? #
  • 24-yard punt. 16-yard first-down run. Need I say more? #
  • And then the Packers bail out the Bears, with some utterly stupid play-calling from mid-field. Why go for 2 homerun balls there? #
  • Seriously? You let yourself get sacked out of FG range on 3rd & 6 from the 27? The Packers offense really is trying to keep the Bears in it #
  • So, does *either* team want to win this NFC Championship? Two near-safties, followed by a muffed punt? #ugly #
  • Jay Cutler is throwing with Mark-Sanchez-esque accuracy today. #
  • @LovinBlue I don't really care who wins it. Probably rooting for the Packers, but it won't bother me if the Bears win. in reply to LovinBlue #
  • This time: 11-yard punt, followed by a 10-yard run on first down. Good play-calling, Lovie... :/ #
  • @XL950 followed by a 10-yard run on first down, of course. in reply to XL950 #
  • @18to88 @BankOfWayne and it worked so well the first time, they just did it a second time! in reply to 18to88 #
  • The Packers should act like they want to win this game, and go for it on 4th & 1 from the 36. But what do they do? Punt, of course. #
  • Bad throw by Rodgers; WR tips it: interception. #
  • @coltsgurl4u apparently, Rodgers heard you. in reply to coltsgurl4u #
  • The Bears are in perfect position to play for a half-ending FG. What do they do? Homerun ball: INTERCEPTION #
  • My guess is the booth called for a review for down-by-contact, not for an incompletion. #
  • Uhhh.... he was CLEARLY tapped on the helmet on the way to the ground. How was he not down by contact at the 2? #
  • Please: someone explain to me why the Packers, up 14, with the Bears offense doing NOTHING, are still trying the homerun balls? #
  • WOW! That was a CHEAP pass interference call. Jacob Tamme would like a second opinion. #
  • @norcross but they've been successful with moving the ball at-will with shorter throws. Up 14. Kill the clock. in reply to norcross #
  • @XL950 or perhaps, only throw the flag when it's, you know, actually pass interference... in reply to XL950 #
  • Rodgers just threw his second interception in scoring position. Todd Collins now in at QB for the Bears. #
  • @Skitzzo I watch the contact that *doesn't* get called in Colts games; that didn't look anywhere *near* DPI to me... in reply to Skitzzo #
  • Sorry, make that a sack and a pick for Rodgers in scoring position. His first pick was from just outside FG range. #
  • @LisaSabinWilson not Rodgers' finest decision-making performance today. You guys should be up at *least* 20-0 by now. in reply to LisaSabinWilson #
  • @LovinBlue you can tell a difference between the two? in reply to LovinBlue #
  • Worst decision to field a punt of all time? Survey says: yes. #
  • I think Urlacher is just about the only Bears player who decided to show up to play today. #
  • @keder yes in reply to keder #
  • @dmataconis he can't now. The Bears put in their #3 QB. in reply to dmataconis #
  • @dmataconis dunno; I just know that once the #3 QB goes in, #1 #2 are done b/c #3 is emergency QB & doesn't count against active game roster in reply to dmataconis #
  • If Jacob Hanie leads da Bears back into the game & Chicago wins do the Bears have a QB controversy on their hands going into the Super Bowl? #
  • This time, Chicago punted 24 yards, and it wasn't even a touchback. #punting #fail #
  • Jay Cutler is in the game. He's wearing the #12 jersey for the Green Bay Packers. #
  • This game has had SIXTEEN punts. 8 of them have netted less than 35 yards. 6 have netted less than 30 yards. #punting #fail #
  • Jacob Hanie has now thrown 3 Touchdowns: 2 to the Bears, and one to the Packers. #
  • That was a sketchy call for intentional grounding. There WAS a receiver in the area; he got hooked/pulled to the ground, Reggie Wayne-style #
  • @18to88 @rtm237 clearly. That statement can only be borne out of complete ignorance. in reply to 18to88 #
  • @CrizzleColts @18to88 "fourth and ballgame" doesn't count as a gutsy playcall. in reply to CrizzleColts #
  • I almost wish that idiot DB had fumbled the ball for trying to run back that interception. #takeakneeforthewin #
  • @Skitzzo for what it's worth, their ball-control was worse than their clock management. in reply to Skitzzo #
  • @Shake1n1bake that, too - though there's no harm in picking it off it to prevent an errant catch. in reply to Shake1n1bake #
  • @coltsgurl4u sure... jinx the Steelers. Works for me! in reply to coltsgurl4u #
  • @technosailor I hear there's a football game on in reply to technosailor #
  • @technosailor @TurleyCEO that's okay, so did the Bears. in reply to technosailor #
  • @Frumph sleep? Ah, so that's why you disappeared! in reply to Frumph #
  • @nacin must be a filter called dont_format_<3_dangit()... in reply to nacin #
  • @WordPressKC a #wordcamp in Missouri? Awesome! #
  • @WordPressKC I might have to try to make it over there. in reply to WordPressKC #
  • @WordPressKC any interest in a discussion of Themes from the perspective of the Repository/Theme Review Team? in reply to WordPressKC #
  • @18to88 can you do a comparison of Big Ben's last pass to Manning's pass to Blair White? It looked almost *exactly* the same height. #
  • @18to88 you think? in reply to 18to88 #
  • @PeytonsHead except for me. Must try harder. in reply to PeytonsHead #
  • @18to88 but he was going to ground. Hmm... maybe I wasn't paying close enough attention. in reply to 18to88 #
  • I just threw up a little in my mouth hearing Ben the Rapist Roethlisberger saying "God is good" in the post-game interview. #
  • @18to88 we might be quibbling. Would you say they were within 1 foot of each other, in height off the ground (e.g. 1ft vs 2 ft? off ground)? in reply to 18to88 #
  • @18to88 I don't think it was that low. White was in the air; could see shadow beneath. At the time I put that pass at/just below knee height in reply to 18to88 #
  • @18to88 I'd call that just below knee height. Not worth being pedantic over, however... in reply to 18to88 #
  • @coltsgirl17 me too, in June in reply to coltsgirl17 #

Beginning Git Cheat Sheet

Filed in Web DevelopmentTags: Git, Oenology, Themes, WordPress

Since Theme developers don't (at least, not yet) have SVN-commit access for the WordPress Theme Repository, I decided to host Oenology on GitHub. Git is an entirely different beast from Subversion, so it took me a bit to figure out exactly how to use it.

So, for the most part, this post is my own personal cheat sheet, though perhaps someone else new to Git might also find it helpful.

Initial Setup

Generate SSH Keypair:

ssh-keygen -t rsa -C "[email protected]"

Setup local system's global Git username and password:

git config --global user.name "User Name"
git config --global user.email [email protected]

Setting Up a Local Repository

One major difference between SVN and Git that I quickly discovered is that SVN defaults to setting up subdirectories for the working copy (/trunk) and previously tagged versions (/tags), but Git does not. So, whereas with SVN, my local repository checkout (i.e. the directory tracked by SVN) was simply a directory called /oenology, with Git, it made more sense for me to create my own subdirectories: /master for the working copy and /tags for tagged versions, and then do my Git checkout in /oenology/master.

Change path to working directory:

cd ~/<path>/oenology/master

Initialize local directory as a Git repository:

git init

Checkout the remote repository:

git remote add origin [email protected]:<username>/<repository>.git

Working With Git Repositories

Add (stage) all files in the local directory to the repository:

git add .

Commit (snapshot) all file changes in the local directory:

git commit -m "Commit Message"

Push all snapshots to the remote repository:

git push origin master

Working With Tags

Tag the current snapshot:

git tag -a "Version Number"

Push all tags to the remote repository:

git push origin --tags

Delete a tag:

git tag -d "v12345"
git push origin :refs/tags/v12345

Working With Branches

List Branches:

git branch

Create a Branch:

git branch {branch}

Switch to a Branch:

git checkout {branch}

Push a Branch:

git push origin {branch}

Merge a Branch:

git merge {branch}

Delete a Branch:

git delete -d {branch} // only deletes the branch if all changes are merged
git delete -D {branch} // deletes branch, regardless of merge state
