A call for aid

Orac has posted a call for aid: the offices used as a mailing address by the Holocaust History Project (THHP) were burned down by arsonists. Orac has all the details here.

Orac's requested aid is simple: turn this negative into a positive by spreading news of the Holocaust History Project.

Holocaust History Project
The Holocaust History Project is a free archive of documents, photographs, recordings, and essays regarding the Holocaust, including direct refutation of Holocaust-denial.
So, if you can, spread the word; the Holocaust History Project is a good organization that could use your help.

Shark vs. crustacean ... we know who wins

A colleague this morning informed me of a discovery of a new shark species, which was neat, but didn't thrill me. But then I got home and read on BoingBoing and Pharyngula about a new deep-sea crustacean; I immediately started looking for the journal article (its full text can be found as a PDF here). I mean come on, one lives only a few hundred feet down in some boring ol' coastal sea and has pretty typical vertebrate anatomy, while the other lives in 7,500-foot deep water near hydrothermal vents, is covered in fine hairs setae, and is blind. Which would you rather learn about?

new crustacean
Kiwa hirsuta

The journal article (PDF) has many more pictures of the new crustacean, as well as a description of its habitat:
The new species occurs at densities of one to two individuals per 10m^2, more or less regularly spaced on the zone of pillow basalt surrounding active hydrothermal vents (Fig. 2). The species co-occurs with galatheid squat lobsters (genus Munidopsis Whiteaves, 1874), crabs (genus Bythograe Williams, 1980), vent mussels (genus Bathymodiolus Kenk & Wilson, 1985) and buccinid gastropods. Specimens of Kiwa hirsuta n. gen., n. sp. were also observed on extinct chimneys and at the base of black smokers, among vent mussels, where shimmering milky water emanates. Like other vent decapod crustaceans Kiwa hirsuta n. gen., n. sp. is probably omnivorous. Specimens were observed in situ consuming tissues of mussels damaged by submersible sampling activities.
The researchers used genetic data to determine that this new crustacean is in a completely new family (Kiwaidae) contained within superfamily Galatheoidea and infraorder Anomura. The anomurans most people are likely to know are hermit crabs, which are in a different superfamily (Paguroidea) than this newly discovered species. True crabs (the kind you have likely eaten) fall into another infraorder (Brachyura), and lobsters are in yet another infraorder (Astacidea). So, in other words, this is not a new crab, lobster, or hermit crab; the closest known relatives of this new species are squat lobsters.

A look into the future

[Warning: a rambly, self-indulgent post follows. If you don't want to read about a community college professor's thoughts on his career path, skip this post.]

Last spring, after being on a hiring committee, writing an NSF grant, being chair of a committee that was actively meeting, and teaching my full load, I proclaimed that I'd never take on that much work again. This spring I'm on two hiring committees, am writing another NSF grant, just submitted another (non-NSF) grant, and am chair of the whole department. Yet again I'm not getting enough sleep and don't have time to spend with my SO or students. Even my friends and coworkers are noticing; a number of them have started telling me (with varying degrees of bluntness) that I'm doing too much and need to slow down.

Last week I visited a local university to be a panelist in a (very neat) discussion with a number of graduate students; due to the vagaries of my schedule I ended up arriving quite a bit early. Before I sat down with my laptop and worked on a grant, I found a quiet spot where I could just think about what I wanted to do in the future. I came to the conclusion that there are three separate paths I can follow:
  1. Focus my time on research.
  2. Focus my time on being department chair.
  3. Focus my time on teaching.
What struck me about this idea of separate paths was that it made me realize that in the past year I've been trying to work on all three of those paths simultaneously. I've been administering the department (spending ~20% of every week on it), continuing outside research (both applying for grants and advising students interested in research), and improving my teaching (e.g., publishing my lab manual) all at once. While these are all fun and fulfilling tasks, I feel like I'm in Root Beer Tapper and the customers (work) just keep piling up at the end of teach table (separate career path) faster than I can take care of them all. The faster I flip between each table, the faster work keeps piling up.

So, I've made a decision. Starting this fall I'm going to stop straddling all three paths and just choose one. Here's my three-option plan for accomplishing this:
  • The grant I applied for last week includes funding to release me from about 1/3 of my teaching duties. This would allow me to only have two teaching preps a week, and thus give me enough time to do research properly, but still be able to improve the course I'd be teaching. If the grant is funded, I won't seek re-election as department chair (my term ends this spring).
  • If the grant doesn't get funded, I'll consider continuing as department chair. However, for this to happen the administration is going to need to increase my release-time compensation so that it's on par with the amount of work I'm doing. This is unlikely to happen, however, as I've been told that in the fall the administration will remove the release time I'm currently getting and just give me a stipend. This means that I'd have to teach my full load of courses, and then do department chair work on the side; that wouldn't be fair to my students. So, unless I get that release time back (and get more added), I won't be chair. Many thanks to Orac's wise commentary (via e-mail) for contributing to this decision.
  • If neither the research nor department chair propositions come through, I'll happily stop doing both and instead focus on my teaching. I may continue to dabble in research, and I'll continue to serve my department, but not in the leadership roles I'm currently occupying.
One thing that long-time readers (and friends and family) may notice is that the first path I list involves doing research, yet I specifically started teaching at a community college so I wouldn't have to do research. I haven't changed my mind on this; I still love the teaching-focused aspect of being at a community college, and I still don't want to be forced to do research.

The research that I'm carrying out appeals to me for many reasons, not the least of which is that it's completely optional. Even if this grant comes through, it's only for a one-year term, and at the end of that term if I don't like where I am, I can return to teaching full-time. Additionally, my campus has a unique field resource available for research; if we (the biologists at my campus) don't use it, then my campus will likely lose this resource forever. And, most importantly, my research gives first and second year biology majors at a community college an opportunity to get involved in field biology research. When I started this project a little more than a year ago I had no idea how many students would be interested, but I've now had dozens of students participate (or show interest) in the research, and they all love it. So, in reality, the research I'm doing is just another biology course I'm teaching; it's just a very advanced one.

Jill wins a prize for research blogging

Jill (of jill/txt) has won a prize for research blogging, and even got a call from the "top brass" of her university congratulating her. The funniest part of her post is her conclusion:
I have this sudden urge to email Ivan Tribble, who famously claimed in The Chronicle of Higher Education that blogging would guarantee you not getting an academic job, and tell him the news. Heh.

You can be tracked by your printer

The Electronic Frontier Foundation (EFF) has reported that some color laser printers are printing unique identifiers that allow trained readers to decode the month, day, year, and time any page was printed, along with the printer's serial number and manufacturer. The technology is apparently being implemented to prevent counterfeiting, but the EFF notes that no laws regarding the information's use currently exist, and that most people don't even know their printers are automatically including this information on every page they print. The EFF has a summary of what they know, along with a guide to decoding the information, complete with sample images.

On a separate (more humorous) note, the EFF is now selling shipping tape printed with the fourth amendment (find it in the EFF store). BoingBoing suggests you cover your luggage zippers with it next time you fly.

Political links of the week, take 3

[See also: political links of the week take 2 and take 1.]

Bush Lied: A big story this week was the release of pre-Katrina conference calls wherein President Bush was directly told "I don't think any model can tell you with any confidence right now whether the levees will be topped or not but that is obviously a very, very grave concern," which directly contradicts his later statement that "I don't think anybody anticipated the breach of the levees". This AP story has more:
Homeland Security officials have said the "fog of war" blinded them early on to the magnitude of the disaster. But the video and transcripts show federal and local officials discussed threats clearly, reviewed long-made plans and understood Katrina would wreak devastation of historic proportions. "I'm sure it will be the top 10 or 15 when all is said and done," National Hurricane Center's Max Mayfield warned the day Katrina lashed the Gulf Coast.
"I don't think anybody anticipated the breach of the levees." - A letter to President Bush from representative Conyers based on the recently release briefing videos (linked to above):
Mr. President:

How could you look into the camera and utter those false words when you knew people were needlessly suffering and dying while you were vacationing, hamming it up with country music performer Mark Wills, strumming a guitar?

How can you look at yourself in the mirror every day knowing that, when faced with another crisis of the gravest proportions, you were again beset with uncertainty, indecision, and inaction – anything but the strong leader you purport to be?

How could you take your oath, in god's name, to protect the citizens of this country and then turn your back on a whole city, abandoning them before, during, and long after this horrible tragedy?
Bleak deficit picture in Treasury report concerns lawmakers:
A little-noticed Treasury Department report sent to congressional leaders in December paints a bleaker picture of the nation's finances than is widely accepted ...

According to the 158-page report, the fiscal 2005 federal deficit on an accrual basis was $760 billion, using generally accepted accounting principles that private businesses must use to present their finances.

That is an increase of $144 billion, or 23 percent, over the previous year's deficit of $616 billion.
It's worse than I thought - Orac reports on the cut in funding at the National Institute for Health's National Cancer Institute (NCI):
[T]he NCI budget for 2007 will represent not just a failure to keep up with inflation but a real cut in actual dollars [$40 million] for the second year in a row. And yet we can still manage to afford over $120 million a year to fund the National Center for Complementary and Alternative Medicine.
Where I Catch The NIH With Its Pantaloons Down: A Well-Timed Period post about a possible overstatement on an NIH website of the risks of emergency contraception.

Crucial but Costly Treatment Is Drying Up With Funding: An LA Times article looking at the effect of reduced Medicare funding on patients.
Although budget experts and healthcare economists believe [Medicare] costs must be reined in, Hill's [a patient on Medicare] experience illustrates how hard that is to do without hurting elderly patients.

Hill has a chronic disease in which his immune system attacks the nerves in his limbs, causing weakness and loss of control. The medication he was receiving until last spring is called intravenous immune globulin, or IVIG. One treatment can cost at least $3,000.

Most IVIG patients must receive infusions every three to four weeks, therefore the annual cost can exceed $50,000. According to an industry survey, the average doctor's office would lose from $7,800 to $9,700 a month by continuing to provide treatment at the newly reduced Medicare rates.

"We warned the government," said Dr. Mark Brecher, a University of North Carolina medical school professor who until recently headed an advisory committee of the U.S. Department of Health and Human Services. "The committee advised them a major problem was imminent, and to the best of my knowledge, I have seen no real action other than checking on the inventory [of IVIG]."

The panel Brecher headed called on the Department of Health and Human Services to declare a health emergency and override the reimbursement cutbacks. Administration officials have not done so.
Fire Victims Feel Burned by Lawmakers Tied to Insurers: Another article in the LA Times, this one looking at how California politicians have stymied reforms to insurance laws.
Karen Reimus' San Diego house was obliterated by the 2003 wildfires, leaving nothing recognizable except a charred jogging stroller and her daughter's burned bicycle.

Yet her insurer insisted that she catalog each of her family's destroyed personal items — down to pens and tampons — if she wanted to be reimbursed.

"When insurance companies are selling peace of mind the way they do in their advertisements, nobody has any inkling of the hoops you are going to have to jump through," said Reimus, a 39-year-old lawyer and mother of two. She reached a settlement with her insurer after months of wrangling.

Dozens of similarly frustrating experiences prompted Reimus and other survivors of one of the worst wildfire seasons in California history to urge that new rules be imposed on insurers. But the most far-reaching efforts were derailed by a panel of state lawmakers that is closely aligned with the insurance industry, offering an unusually clear window on how Sacramento works and how legislation can be determined by a handful of well-placed politicians.
US to extend military executions rules to Guantanamo Bay:
The US military is clearing the way for executions of condemned terror suspects to take place at the Guantanamo Bay detention facility.

...

Previously executions could only take place at a military jail in Kansas but now death sentences can be carried out anywhere, including the Guantanamo Bay naval base in Cuba.

The army has confirmed the new rules will also apply to any Guantanamo detainee sentenced to death at a specially convened military tribunal.

A tree of life ...

Carl Zimmer has linked to a beautiful phylogeny displaying the diversity of life:

tree_of_life-feb-25-800pix

Zimmer's article does a great job of explaining what the tree is, and how to read it, so if you're not used to reading phylogenies just pop over there to learn more. It really is a thing of beauty; my SO and I each spent probably more than half an hour exploring it tonight.

The phylogeny was created by comparing the sequences of 31 genes shared by organisms that have had their entire genomes sequenced. This limitation to include only completely sequenced organisms partially explains the lack of eukaryotes (animals, plants, etc.), as they're much more difficult to sequence. One thing that is somewhat irksome to this entomologist, however, is that only two species of insects (~.00026% of all named insect species; both are flies) were included, while seven chordates were included (~0.014% of all named chordate species), but that's just a symptom of the bias of genome sequencers (and researchers in general).

For those who are curious, here are the common names (and descriptions, where appropriate) of the eukaryotes included:
The authors report that they'll update the phylogeny as more genomes are sequenced; see their homepage for the most recent version.

(via my dad, who waxed rhapsodic about the figure on the phone tonight)

Update 3/5 12:30pm - Curious about all those non-eukaryotes? The Genome News Network has an illustrated quick guide to sequenced genomes that comes complete with the common name of the organism, a summary of its ecology, and why it was sequenced. They also have a very useful alphabetical index.

Some quick humor

A human heart modeled out of Valentine's Day candy hearts.

A summary, and downloadable version, of a Penn & Teller video game. The game apparently has a hilarious mini-game:
The most infamous part was "Desert Bus," a "VeriSimulator" in which you drive a bus across the straight Nevada desert for eight hours in real-time. Then you drive it home. Also, I'd read the bus veers to the right, so you can't just leave the joypad propped up. The rumor was that if you won the game, you got one point.

Brief news

Well, it turns out that this post was even more timely than I thought. The last three days have been crazy, and Friday promises to continue the trend. I apologize for the lack of posting.

Here's a summary of some recent big news:

1) My SO's job is now officially permanent. Yippee!

2) In a meeting with the president of the college this week, a proposal was brought up that could potentially reassaign a large portion of my time to doing (and supporting) field biology research. This is an amazing opportunity, partially because it would pay me to work on things I've already been doing in my spare time. Nothing is certain, but if it's even going to be a possibility I have to submit a full proposal by the end of the day, even though I only found out about this two days ago.

I'm really going to need my spring break.

Elegant chocolate frosting

My SO and I discovered the recipe for our lemon butter frosting when we were just starting to bake cakes; we like it so much that we frost more than half the cakes we bake with that frosting. Sadly, we haven't had as much luck with chocolate frosting. Over the years we've tried a number of different recipes, but most were either too gooey, too hard, too granular, or just not chocolatey enough.

All of our trials and tribulations ended, however, when we made Joy of Cooking's chocolate ganache frosting: it's easy to make, tastes like it was made from chocolate truffles (which it functionally is), looks shiny and smooth when frosted onto a cake, and is the perfect silky texture at room temperature. It even holds up to refrigeration well. Since we just baked a cake and frosted it with this frosting tonight, it's this week's end-of-the-week recipe blogging post.

3/4 cup heavy cream
8 ounces semisweet chocolate, chopped into small pieces (we use chocolate chips)
1 tablespoon flavorful liquor (optional; we used rum this time)

1. Bring the heavy cream to a boil in a non-stick pot over medium-high heat, stirring occasionally.
2. Remove the pot from the heat and add the chocolate. Stir until the chocolate has melted into the cream.
3. Let rest, covered, for 10 minutes.
4. Whisk until smooth, and then whisk in the liquor. Let sit at room temperature, stirring occasionally, until it's the proper thickness to frost. In our ~70F kitchen this took about 45 minutes, though it will depend on the surface-area-to-volume ratio of the chocolate in your pan.
5. Frost the cake. Be sure the cake is close to room temperature when you frost it; if it's too hot, the frosting will melt and run off, but if it's too cold, the frosting will congeal instantly.
6. Serve the cake at room temperature.

Notes:

This recipe makes enough to thinly frost and fill a cake composed of two 9" rounds. It would easily cover a 9" x 13" sheet cake.

Joy reports that you can use either semisweet or bittersweet chocolate for the frosting; we've only used semisweet. Joy also reports that you can use either butter or heavy cream; we've used either all heavy cream or a mixture of heavy cream and butter with good results. This frosting can also be used as a glaze if you pour it onto the cake while the frosting is still quite warm.

I'd suggest frosting the cake while the frosting is still a bit more liquid than a typical butter-based frosting, as then the frosting will flow just a little after you spread it, removing most of your tool marks and leaving your cake looking smooth and shiny.

Game copy protection opens security holes

Boycott Starforce is a webpage encouraging users to boycott copy protection software that's used by a number of modern PC games. The problem with this copy protection software is that, like Sony's rootkit DRM software, it can wreak havoc with your computer and open up security holes:
The Starforce drivers are often linked to system instability and computer crashes. If these problems occur, the end-user would be unware as to the cause of the problem, and would be helpless to solve the problem.

For example, here's one of the common problems brought by Starforce: under Windows XP, if packets are lost during the reading or writing of a disk, XP interprets this as an error and steps the IDE speed down. Eventually it will revert to 16bit compatibility mode rendering a CD/DVD writer virtually unusable. In some circumstances certain drives cannot cope with this mode and it results in physical hardware failure (Most commonly in multiformat CD/DVD writer drives). A sure sign of this step down occurring is that the burn speeds will get slower and slower (no matter what speed you select to burn at). Starforce, on a regular basis, triggers this silent step down. ...

Moreover, the Starforce drivers, installed on your system, grant ring 0 (system level) privileges to any code under the ring 3 (user level) privileges. Thus, any virus or trojan can get OS privileges and totally control your system. Since Windows 2000, the Windows line security and stability got enhanced by separating those privileges, but with the Starforce drivers, the old system holes and instabilities are back and any program (or virus) can reach the core of your system by using the Starforce drivers as a backdoor.
There's a list of games that use Starforce here; thankfully Civ IV isn't on the list, but I'm saddened to learn that Freedom Force vs. The Third Reich (which I bought a few months ago) uses the copy protection system.

Political links of the week, take 2

[See also: political links of the week take 1.]

Bush and Blair have brilliantly done Bin Laden's work for him: An editorial in The Times arguing that Bush and Blair have done nearly as much damage as Bin Laden himself.
... The 9/11 “changes everything” mantra began as an explanation of a national trauma and a plea for sympathy. It was hijacked to validate the latent authoritarianism of democratic leaders.

America asks the world to believe itself so threatened as to require the kidnappings of foreign citizens in foreign parts, detention without legal process, the curbing of free speech and derogation from all international law. It asks the world to believe that it must disregard the Geneva conventions and employ foreign dictators to help it to torture at random. It uses the same justification for occupying Iraq and Afghanistan. The world simply refuses to agree. Only cringeing Britain appeases such actions and calls them merely “anomalous”. There are madmen aplenty, but they do not constitute a war.

Even America’s most robust champions plead that this is all grotesquely counter-productive. What is frightening is not the evil of much American foreign policy at present but its stupidity; the damage it does to its own objectives.
New Documents Provide Further Evidence That Senior Officials Approved Abuse of Prisoners at Guantánamo: An ACLU press release reporting on documents they recently obtained.
The May 2003 memo specifically names Maj. Gen. Geoffrey D. Miller, who was then Commander of Joint Task Force-Guantánamo, as having favored interrogation methods that FBI agents believed "could easily result in the elicitation of unreliable and legally inadmissible information." The memo states that FBI personnel brought their concerns to the attention of senior Defense Department personnel but that their concerns were brushed aside.

Other documents released by the ACLU today provide more evidence that abusive interrogation methods used at Guantánamo were endorsed by senior officials. One FBI e-mail, dated May 5, 2004, states that "hooding prisoners, threats of violence, and techniques meant to humiliate detainees" were "approved at high levels w/in DoD." Another FBI e-mail states that certain techniques alleged to be abusive by some FBI agents were "approved by the Deputy Secretary of Defense."
Privacy Guardian Is Still a Paper Tiger: An article in the LA Times reporting on a government board created to protect civil liberties.
For Americans troubled by the prospect of federal agents eavesdropping on their phone conversations or combing through their Internet records, there is good news: A little-known board exists in the White House whose purpose is to ensure that privacy and civil liberties are protected in the fight against terrorism.

Someday, it might actually meet.

...

Foot-dragging, debate over its budget and powers, and concern over the qualifications of some of its members — one was treasurer of Bush's first campaign for Texas governor — has kept the board from doing a single day of work.
U.S. Reclassifies Many Documents in Secret Review: A New York Times article discussing a secret program to reclassify thousands of previously declassified historical government documents.
... because the reclassification program is itself shrouded in secrecy — governed by a still-classified memorandum that prohibits the National Archives even from saying which agencies are involved — it continued virtually without outside notice until December. That was when an intelligence historian, Matthew M. Aid, noticed that dozens of documents he had copied years ago had been withdrawn from the archives' open shelves.

Mr. Aid was struck by what seemed to him the innocuous contents of the documents — mostly decades-old State Department reports from the Korean War and the early cold war. He found that eight reclassified documents had been previously published in the State Department's history series, "Foreign Relations of the United States."

...

National Archives officials said the program had revoked access to 9,500 documents, more than 8,000 of them since President Bush took office. About 30 reviewers — employees and contractors of the intelligence and defense agencies — are at work each weekday at the archives complex in College Park, Md., the officials said.
Declassification in Reverse - The Pentagon and the U.S. Intelligence Community's Secret Historical Document Reclassification Program: A detailed report by The National Security Archive ("the world's largest non governmental library of declassified documents") discussing some of the documents that have been removed from the National Archives by the secret reclassification program discussed in the New York Times article (above). The National Security Archive article also includes scans of some of the documents that have now been reclassified.

Keep e-mailing me, please

Both PZ Myers and Timothy Burke nicely summarize my views on a New York Times article that attempts to cast student e-mails as the evil of modern academia. The article is ridiculous; even the "outrageous" examples of student e-mails they cite (such as a freshman asking which school supplies to purchase) seem perfectly reasonable. At the very least these faculty should grow spines; if you don't want to give out your lecture notes to students who miss class, then just respond and explain your policy. If you don't want to reply to a midnight e-mail, then don't (or, even better, explain that you only respond to e-mail during business hours). And finally, if you don't want to receive criticism regarding your lectures, then what are you doing giving them to an audience in the first place?

Long days and zombie roaches

Fourteen-hour days are just not much fun. What's even less fun is when the majority of those 14 hours are spent not teaching, but administering and doing other miscellany. In the last few weeks I've found that even though I'm working nearly constantly during the week, I end up with only a few minutes to review my slides before rushing off to lecture or lab. In fact, thanks to the Qwizdom debacle last week, I walked into lecture one day without even having reviewed the second half of my lecture. Considering that I chose to teach at a community college precisely so I could focus my entire professional effort on teaching, this is extremely frustrating.

But enough complaining; here's some cool biology for you to enjoy:

Carl Zimmer has a detailed report on Ampulex compressa, a parasitic wasp that turns roaches into zombies:
The wasp slips her stinger through the roach's exoskeleton and directly into its brain. She apparently uses sensors along the sides of the stinger to guide it through the brain, a bit like a surgeon snaking his way to an appendix with a laparoscope. She continues to probe the roach's brain until she reaches one particular spot that appears to control the escape reflex. She injects a second venom that influences these neurons in such a way that the escape reflex disappears.

From the outside, the effect is surreal. The wasp does not paralyze the cockroach. In fact, the roach is able to lift up its front legs again and walk. But now it cannot move of its own accord. The wasp takes hold of one of the roach's antennae and leads it--in the words of Israeli scientists who study Ampulex--like a dog on a leash.

And it only gets better from there - go enjoy. Biology's so damn cool.

American potato salad - Radagast's SO's style

While I'm on the topic of potato salad, I might as well post a traditional American potato salad recipe. My SO prefers a relatively basic American potato salad, and since we had some extra potatoes last night after making our German potato salad, we also made a batch of my SO's favorite (very oniony) potato salad. Radagast even enjoys it despite it lacking hard-boiled eggs and pickles. This recipe is this week's second end-of-the-week recipe blogging post.

3 pounds potatoes, whole, with skins
1 1/2 cups mayonnaise
1 medium onion, finely chopped (~1 cup chopped)
1/3 cup chopped fresh parsley
1 medium clove garlic, finely minced or pressed with a garlic press
3 tablespoons buttermilk (or milk)
2 teaspoons kosher salt (or to taste)
1/2 teaspoon ground black pepper

1. Wash the potatoes and trim off any bad spots.
2. Add the whole potatoes (skin on) to a large pot of salted water, and bring to a boil.
3. Simmer the potatoes until they are tender throughout; test by piercing with a fork or knife. This will likely take anywhere from 20 to 40 minutes, depending on the size of the potato; we check the potatoes about every five minutes once they've been cooking for 20 minutes. Remove any small potatoes that finish cooking before larger ones.
4. Drain the potatoes and let cool to a comfortable handling temperature (but do not refrigerate).
5. Cut the potatoes into bite-sized pieces and put into a bowl.
6. Mix the mayonnaise, onions, parsley, garlic, buttermilk, salt, and pepper in a separate bowl.
7. Add the mayonnaise mixture to the potatoes, and mix gently.
8. Refrigerate for at least a few hours to allow the flavors to meld; we serve it cold.

Notes:

Vary the amount of onion to suit your tastes; we prefer it very oniony, but if you want it milder, use less onion or use a sweet onion. If at all possible use fresh parsley, as dried parsley isn't nearly as flavorful.

We typically don't worry about the variety of potatoes we use, though in general waxier potatoes hold their shape better. Last night we used "Butter Golds" and they were very good.
