Who would have thought it?

You can get botulism from prison wine, aka “pruno“, aka “that stuff that’s frequently fermented in a cell block toilet or other places just as disgusting”.

(You know where else you can get alcohol from, with less risk of botulism? Sourdough starter. No, really; the liquid that separates out and rises to the top if you leave it sit is somewhere between 12% and 14% alcohol. I haven’t tried drinking any of it, but I suspect it tastes a little better than pruno.)

Let my people eat bread.

Thursday, February 7th, 2013

My mother sent along an article from the WP that I had missed, “Better bread starts with a sponge“, which discusses some sourdough techniques for home bakers.

I appreciate her sending that along, and have already sent her some comments. But since they’re easy blog fodder, I’ll repeat them here. I don’t really have any problems with Marcy Goldman, or her article; I want to try her “Favorite French Bread“. But there are some questions I have and comments to make.

  1. Goldman quotes Cook’s Illustrated as saying home bakers should “forgo a starter to save time and simply add vinegar for that characteristic acidic taste”. This is, so far, the dumbest thing I’ve read in 2013. To her credit, Goldman does not endorse this, but I expect better from CI and that tweedy little bow-tied jackass.
  2. Why is this dumb? Because anyone can make a starter. It is not the nuclear rocket brain surgery. It isn’t hard. I have made starters and baked with them, and I’m not Thomas Freaking Keller in the kitchen. All you need is flour, water, and time; that’s how the original Alaskan sourdoughs were made. Yeast is a possible addition, but isn’t strictly needed. (I’ll touch on that in a minute.) As far as time goes, you can get a starter going in 72 hours, and it will keep indefinitely with reasonable care.
  3. Goldman’s stater recipe calls for a cup of spring water, 1 1/4 cups of unbleached bread flour, 2 tablespoons each of whole-wheat and rye flour, and 1/2 teaspoon of instant yeast. The starter recipe I’ve been using calls for 3/4 cup of milk, “heated to a simmer and cooled to 100°F”, 1 cup flour (white, whole-wheat, or rye) and 1 1/2 teaspoons of yeast. Both make enough starter for one loaf in their respective recipes; I’ve doubled the recipe amount for my starter, and am feeding it with 1 cup heated milk and 1 cup rye or whole-wheat flour whenever I pull some starter out. That way, I always have enough starter. (I keep it in a crock on the back of my stove.)
  4. Here’s the thing, though: if you’re starting your starter with yeast, aren’t you just…growing more of the same yeast? I mean, if I want Fleischman’s, I can go buy that stuff all day long at the HEB. Or do the natural yeasts in the air eventually overwhelm your starter yeast? I have heard it said that’s what happens with packaged sourdough starter, like you might get as a souvenir in San Francisco or Alaska; you may get it home and bake some bread, but eventually the original strain will get overwhelmed by your wild local yeasts. (That doesn’t mean I don’t want to try baking with one of those starters; I do.)
  5. The one starter I’ve found that doesn’t call for added yeast is Nancy Silverton’s in Breads from the La Brea Bakery. I’d like to try that, but it takes 14 days to get to the point where you’re ready to bake with it, and it seems very fussy. While I was looking up Silverton’s starter, I found this starter recipe from Michael Ruhlman, which doesn’t take 14 days, doesn’t call for added yeast, and also looks like something worth trying.
  6. Speaking of Ruhlman, he’s probably worth a post of his own at some point. (I’ve been reading Ratio: The Simple Codes Behind the Craft of Everyday Cooking and The Making of a Chef: Mastering Heat at the Culinary Institute of America, the latter of which I paid $1 for at the Austin Public Library bookstore. At one point in Making, Ruhlman mentions a CIA chef who has a starter he’s kept going since 1985; the book came out in 1997, so that was at least a ten-year-old starter.)

The volume of spam comments has gotten out of control again; there were more than 600 waiting to be cleaned out this morning. Akismet does a fine job of stopping the spam from being posted (and I can count the number of false positives since I started this blog on the fingers of one hand), but I still have to go through the queue and empty it at least once a day.

In an attempt to mitigate this problem, I have installed the WP-Ban plugin and will be configuring it to block IP addresses, or IP address ranges, that are a source of spam. I feel slightly bad about doing this, but in the 30 minutes I’ve had WP-Ban installed, it has blocked 15 spam attempts.

If anybody runs into problems with this, please let me know. I’ve added my contact email address to the WP-Ban page as well. We’ll see if the Beats by Dr. Dre scumbags, or any of the other spammers, try to contact me.

LAPD watch.

Thursday, February 7th, 2013

I’m not going to snark here, because this first story is sad and awful.

Christopher Jordan Dorner used to be an LAPD officer. He was fired in 2009. Dorner claimed that his training officer kicked a suspect; the LAPD found that claim was false and terminated Dorner.

Dorner has apparently been nursing a grudge since that time, both against LAPD and specifically against one of the people involved in the review process that led to his firing.

Dorner is believed to have shot and killed two people at an apartment complex on Sunday; one of those people was the daughter of the review officer he had a grudge against. (The other was her boyfriend.)

Dorner is now also believed to have shot three police officers earlier this morning, killing one. He has not been captured yet.

But LAPD and the Torrence Police Department have been involved in two shootouts with “vehicles matching the description of the one sought in connection with Dorner”.

“Now it appears neither of them are directly related,” Chase said. “In both of them, officers believed they were at the time.”

In other news, the LA County Sheriff’s Office wants to fire seven deputies for their alleged involvement in a secret “clique” called the “Jump-Out Boys”.

In the case of the Jump Out Boys, sheriff’s investigators did not uncover any criminal behavior. But, sources said, the group clashed with department policies and image.
Their tattoos, for instance, depicted an oversize skull with a wide, toothy grimace and glowing red eyes. A bandanna with the unit’s acronym is wrapped around the skull. A bony hand clasps a revolver. Smoke would be tattooed over the gun’s barrel for members who were involved in at least one shooting, officials said.

The other side of the story:

One member, who spoke to The Times and requested anonymity, said the group promoted only hard work and bravery. He dismissed concerns about the group’s tattoo, noting that deputies throughout the department get matching tattoos. He said there was nothing sinister about their creed or conduct. The deputy, who was notified of the department’s intent to terminate him, read The Times several passages from the pamphlet, which he said supported proactive policing.

School’s in.

I’ve mentioned previously my belief that higher education will fundamentally change in the next decade, especially with the growth of online courses. The biggest thing that folks have been waiting on is college credit: almost all online courses that I’ve seen so far (with the exception of university specific correspondence programs) did not offer credit for course completion.

The LAT reports that Coursera, one of the major online course providers, and the American Council on Education have reached an agreement. ACE will recommend that colleges accept four Coursera courses for college credit:

It is usually free to take a course through Coursera and other similar groups, including Udacity and edX. However, Coursera charges students $30 to $99 for a completion certificate for a class taken under surveillance monitoring that includes individualistic typing patterns to prove a student’s identity. For an additional $60 to $90, a student will be eligible for the ACE credit by taking final exams proctored through webcams.

The four courses in the Coursera/ACE agreement are:

  • a pre-calculus class offered by UC Irvine.
  • a calculus class offered by the University of Pennsylvania.
  • two classes offered by Duke in genetics and biodiversity.

ACE is also recommending that universities accept an algebra course from UC Irvine for “pre-collegiate remedial or vocational credit”.

This gives me a chance to mention something else that’s been going on. I previously noted that I was taking the Stanford University/Class2Go online course, “An Introduction to Computer Networks“. The course wrapped up at the end of November, but I’ve been waiting on various things before I posted about it.

I’m glad I took the course. I learned a great deal from it, especially about the lower levels of IP, TCP, UDP, and routing protocols. There was a lot of sweat in this course; I am willing to say that it was probably more difficult for me than any course I took at St. Edwards. Part of the difficulty may have been the self-paced nature of the course; I got a little behind at a few points and had to work hard to catch up. I think the course would also have been easier for me if I had purchased the suggested, but not required, textbook when I started the course. I didn’t do that at the time because the text was going for more than $100; I found a used copy at Half-Price about halfway through the course and paid about $25 for that.

Unfortunately, the Class2Go presentation of this course was also very buggy. You’d watch videos of lectures, interspersed with multiple-choice questions. Except sometimes the questions wouldn’t pop up. You could also watch the videos without the questions, and answer the questions in a separate window; except even then, some of the questions wouldn’t pop up until the third or fourth pass through.

The actual lecture videos, for the most part, played back okay. There were optional guest lecture videos that you could download as well. I did that, but some of the videos are huge, and don’t have smaller versions available. The Jim Kurose video is 1.7 GB and 1:16 long; by comparison, the 720p version of Top Gear’s “The Worst Cars In the History of the World” is 1.24 GB and 1:13 long. This may not be so bad if you’re on the Stanford campus and plugged into your dorm room’s Ethernet, but over a DSL connection? Not so hot.

One of the things I’ve been waiting on is the final “grade”, for want of a better word. This wasn’t a for-credit course, but you could get a “certificate of completion” from Stanford if you scored above a certain point on the two exams for the course. The two exams had a total of 960 points between them; the final decision by the instructors was that a certificate would be awarded to anyone who scored over 500 points.

So I struggled and I sweated and I waited for the light…and I scored over 500 points on both exams. I won’t say how much over 500, but it was enough, and I finally got my certificate of completion a few days ago.

Having said that, I’m not completely happy with how well I did. I’m seriously considering retaking the course when it is offered again this fall, just to see if I can do better with a textbook in hand.

Banana republicans on trial: February 7, 2013.

Here’s a surprise from the Bell trial: former council member Victor Bello, mister “$100,000 a year as assistant food bank coordinator” was a rat.

Victor Bello had written a letter to the Los Angeles County district attorney with allegations of misconduct in Bell on May 6, 2009, but was not interviewed until 10 1/2 months later, district attorney’s investigator Maria Grimaldo testified Wednesday. She was not asked the reason for the delay nor what the allegations were.

Here’s a great exchange:

“Your monthly salary as a council member is how much a month? investigator Mike Holguin asks. “You said $3,900?”
“No, no, no, no,” Bello replies, according to the transcript. “It’s about $100,000.”
“A $100,000 a year?” Grimaldo asks.
“That’s as a council member for, uh, for Bell?” Holguin adds.

$3,900 a month is what Bello expected to receive as his pension from Bell.

According to the LAT, Grimaldo is the final prosecution witness, so I guess we can expect the defense testimony to start soon. I’d recommend popping a fresh batch of popcorn for that.
