There are thousands of websites out there with details and instructions on how to properly season your cast iron cooking implements. Sadly, very few, if any, actually discuss the science behind what is going on or why one method is better than another. All of them typically reference dozens of oils and fats that should or shouldn’t be used with little or no justification for their choices other than the culinary equivalent of old wives tales.
Flaxseed Oil for Seasoning Cast Iron
About two seasonings ago, I had come across an interesting concept surrounding flaxseed oil and have always meant to try it, but wanted to do some tests and comparisons of my own. After some research, I’ve found Sheryl Canter’s original article which now seems to be referenced by most serious food blogs and sites. I’ll try some tests with in the coming weeks and hopefully get around to reporting some of the results. Time to get the trusty microscope out for some photomicrography!
In the meanwhile, here are some links to what appear to be the forefront of material out there on the subject.
The inimitable McGee has relatively little to say on the subject, so I’ll quote it briefly below:
IRON AND STEEL
Iron was a relatively late discovery because it exists in the earth’s crust primarily in the form of oxides, and had to be encountered in it’s pure form by accident, perhaps when a fire was built on an outcropping of ore. Iron artifacts have been found that date from 3000 BCE, though the Iron Age, when the metal came into regular use without replacing copper and bronze (a copper-tin alloy) in preeminence, is said to begin around 1200 BCE. Cast iron is alloyed with about 3% carbon to harden the metal, and also contains some silicon; carbon steel contains less carbon, and is heat-treated to obtain a less brittle, tougher alloy that can be formed into thinner pans. The chief attractions of cast iron and carbon steel in kitchen work are their cheapness and safety. Excess iron is readily eliminated from the body, and most people can actually benefit from additional dietary iron. Their greatest disadvantage is a tendency to corrode, though this can be avoided by regular seasoning (below) and gentle cleaning. Like aluminum, iron and carbon steel can discolor foods. And iron turns out to be a poorer conductor of heat than copper or aluminum. But exactly for this reason, and because it’s denser than aluminum, a cast iron pan will absorb more heat and hold it longer than a similar aluminum pan. Thick cast iron pans provide steady, even heat.
“Seasoning” Cast Iron and Carbon Steel Cooks who appreciate cast iron and carbon steel pans improve their easily corroded surface by building up an artificial protective layer. They “season” them by coating them with cooking oil and heating them for several hours. The oil penetrates into the pores and fissures of the metal, sealing it from the attack of air and water. And the combination of heat, metal, and air oxidizes the fatty acid chains and enourages them to bond to each other (“polymerize”) to form a dense, hard, dry layer (just as linseed and other “drying oils” do on wood and on painintgs). Highly unsaturated oils — soy oil, corn oil — are expecially prone to oxidation and polymerizing. To avoid removing the protective oil layer, cooks carefully clean seasoned cast iron pans with mild soaps and dissolving abrassive like salt, rather than with detergents and scouring pads.
It’s almost immediately apparent that Canter was inspired to use flaxseed oil by the standard go-to reference which mentions “linseed and other ‘drying oils'”. Since it’s somewhat illustrative of cast iron pans in general, though it doesn’t reference seasoning, I’ll also direct the reader to McGee’s article What’s Hot, What’s Not, in Pots and Pans (New York Times, October 7, 2008) as well as Dave Arnold’s article Heavy Metal: the Science of Cast Iron Cooking.
I’ll note that the Culinary Institute of America’s The Professional Chef (Wiley, 7th edition, 2001) only mentions cast iron in passing on page 91 and doesn’t even use the word seasoning. (There is a more recent 9th edition, which I don’t own, but I doubt it has additional information given the scant nature found in the 7th edition.) Similarly “Iron Chef” Alton Brown’s I’m Just Here for the Food (Stewart, Tabori & Chang, 2011) has some generally fine directions for the beginning chef interested in science, but it doesn’t go past either McGee or the bulk of the online blogs with the common wisdom for cast iron.

In the coming research, I’ll delve into some of the journal literature to see what else I come up with, though I expect that it will be scant at best and not much more than the often cited July 1986 study in the Journal of the American Dietetic Association which discusses iron leaching out of pans into food substances.
Anyone with serious thoughts and ideas in this area is encouraged to share them in the comments.
First a major note of thanks to everyone who helped to make the launch of Little Free Library Branch #8424 a fantastic success. Everyone’s support and encouragement is truly appreciated.
When I was setting up, I naturally brought a book to read, but I did it mostly thinking that only two people might actually stop by. (Hey, I’ll be the first to admit that this is a pretty nerdy and a very local pursuit. It’s easy to click “like” on a post; it’s a whole other thing to visit a small neighborhood library even one with free oatmeal cookies.) Fortunately and very pleasantly, there was a steady stream of people from start to finish, so much so that, as the host, I didn’t get to chat with the visitors as much as I would have liked. Apologies to those I couldn’t chat with more, and even moreso to those who heard answers to the same questions multiple times.
In the end, we had over 20 people and a few pets stop by our little event.
A Double Drive-by… booking?!
Under the heading of “Only in LA” I’ll mention that, the highlight of our grand opening was what I can only describe as a double “drive-by booking.” Fortunately no one was hurt.
About 20 minutes into the event a car drove up with two bibliophiles. They each had a book to donate, but apparently didn’t have the time to park and actually stop for a glass of tea or any cookies. So they simply dropped off their books anonymously and then drove immediately off into the sunset. A few minutes later, another car drove up and did the same thing: they donated a book, said hello, and then proceeded on their way without joining the party! Maybe they had an important book signing or a library event to rush off to? Maybe the library police were chasing them for late fines? The mafia probably would have called foul as they didn’t technically put a foot on the curb or call us out, but hopefully this is as dangerous as things get in the Little Free Library world. One of the donated books had its South Pasadena Library serial number filed off, possibly to keep it from being traced, but authorities are working diligently on the case.
As if the double drive-by wasn’t odd enough, we also had a minivan drove by with a brief stop to ask what was going on. The driver mentioned that the car of several people happened to include two librarians, so apparently we’ll have to keep our eyes peeled for possible additional drive-by bookings.
Thanks for the Donations!
Special thanks go to Adam and Darren who dropped off 3 books. And to Delilah from down the street who was responsible for our first children’s book donation. And we can’t forget the massive donation of 8 books of literary fiction from Jeffrey Stewart making the largest, single one time donation. Several other neighbors dropped books off, and many browsed and found something interesting to take with them. I have to admit that I’m glad that I live in a neighborhood with such great taste in books.
The award for the longest distance donation goes to Samantha Marks who donated a signed copy of her new book A Fatal Family Secret which she shipped from Ellicott City, Maryland just in time for the Grand Opening. It counts as the newest book in our collection as it was just published in May. Since it was checked out almost as soon as it entered the collection, it also rates as our quickest check out; those in a rush may want to pick up a copy at Amazon or other fine booksellers.
In all we had a total of 26 donations for our Grand Opening, bringing our grand total to 49, so far.
As a special mention, the award for the furthest distance traveled to make our grand opening goes to Jocelyn, who came from London on her way to Oklahoma!
Again, a big “Thank You!” to everyone who helped to make our Grand Opening such a lovely success! We look forward to seeing everyone come back soon!
Website and Social Media
For those who weren’t able to stop by, we’re now open 24/7 365 days a year. You can visit our branch online at its own website or by means of your favorite social media platform:
GoodReads: Books currently on our bookshelf (updated regularly – hey, we live on a pretty big hill and walking up to see what’s on tap can be torture, especially in 80+ degree heat)
About two years ago while surfing online I came across the concept of the Little Free Library and instantly fell in love. It turned out I had been driving by one on my commute regularly and had always wondered what it was and what was going on. I immediately had big dreams for building my own. I surfed their website for ideas and building plans. I registered for my placard. I received my placard. I drew up elaborate plans for building my own. I debated buying new parts versus recycling or upcycling parts. [Trigger warning for bibliophiles: addictive material to follow] I spent hours surfing photos of Little Free Libraries on their Facebook, Pinterest, Instagram, and Flickr pages. This is when Little Free Library Envy set in… for almost two years.
Come chat with your neighbors, say hello, and check out the library. If you’re so motivated, feel free to bring a book (or two) to help stock the library.
More information about the Adams Hill “branch” can be found at our library’s page Little Free Library #8424, but the scant basics are below:
The books in our library are always free and never for sale.
Feel free to take a book.
If you have a book you’d like to share, please feel free to donate it.
When you’re done with your book: return it, pass it along to a friend, or release it back into the wild.
You don’t need to “check the book out” or “check it in”, but we do encourage you to sign our guest book and participate via Book Crossing.
It’s a “take a book, return a book” gathering place where neighbors share their favorite literature and stories. In its most basic form, a Little Free Library is a box full of books where anyone may stop by and pick up a book (or two) and bring back another book to share. You can, too!
If you want to learn more about the movement or host your own Little Free Library, please visit their website.
Location
Little Free Library Charter #8424 is located at 1411 Dartmouth Drive, Glendale, CA 91205. It is located at the dog-leg on Dartmouth on the west side of the street. It is just west of S. Adams Street, roughly at the top of the hill.

Our Library Philosophy
Though Chris built and hosts the library, he’s simply a steward or caretaker, of the branch. The library is free and open for the use of our friends and neighbors in Adams Hill and the surrounding neighborhoods. If you’ve stopped to check things out, you’re automatically an associate librarian. It is appreciated if everyone helps to care for and maintain the library.
General Suggestions
The books in our library are always free and never for sale.
Feel free to take a book.
If you have a book you’d like to share, please feel free to donate it.
When you’re done with your book: return it, pass it along to a friend, or release it back into the wild.
You don’t need to “check the book out” or “check it in”, but we do encourage you to sign our guest book and participate via Book Crossing [see below].
Arrangement of Books
Since there isn’t a full time librarian and only so much space, there isn’t (usually) a set order to the arrangement of our books. Since it’s been a long trip up the hill, feel free to stop for a minute to cool off, consider yourself an associate librarian, and rearrange them to suit your whimsy – it is your neighborhood library after all. We only ask that you try to keep any children’s books on the lower shelf for short legs and arms to be able to reach, and that your arrangement ensures all the books fit into the library just in case it rains.
Possible suggestions for arrangements might include:
by size
by color
by the order in which you’ve read them
by author’s first name
by publication date
by publisher or imprint
by topic in reverse alphabetic order
by best to worst (in your opinion or someone else’s)
by those you’ve read and those you haven’t
The options are infinite, so be creative.
Book Crossing
All of our books in the Adams Hill Branch are “traveling” books. We try to register all of them on Book Crossing. This is a free web service for watching the journey of individual books as they meander about the world. If you’d like to, you can enter the BCID number inside the front of the book to see where it’s been and even where it goes after you’ve read it. You can also enter any data, thoughts, reviews, etc. for the book on your own, as well as create a note about where you re-released it. (Note that we don’t expect all of our books to necessarily come back to our branch, but we do ask that you pass them along when you’re done with them.)
Pending people updating the location of books removed, check availability at our Book Crossing Zone.
Donating Books
We gladly accept your donated books.
If you have more books than the little library will fit, please don’t simply dump them! You can leave them in a covered box preferably on our stairs/landing – this will keep our sprinklers and the elements from ruining them or you can contact me through Nextdoor.com. If the library has more books than will fit, we’ll occasionally rotate them to help improve the diversity of the available collection over time.
If you’d like to, please write the titles of your donations into our guest book as this will help us to register them on Book Crossing. (You’re welcome to register them on book crossing yourself prior to donation as well.)
Guest Book
Our library has guest book and a pen. Feel free to write down any thoughts, comments, or suggestions you might have about the library and leave them in the library for the other associate librarians who happen by.
You’ll find a red composition book (and pen) inside our library where you can leave your thoughts and comments. Kindly leave the guest book in the library – it’s the one book we have that doesn’t circulate!
In some part the guest book is meant to help catalog the progress of our library. Below are some suggestions for what you might write into our guest book when you visit:
Patrons/Associate Librarians are encouraged to (optionally) write in the books they donate or check out.
Say hello to your fellow neighbors! You can simply write down the day and time of your visit along with a note for future visitors.
Bringing back a book? Feel free to write in a short review of the book you’re returning so others will know what they’re getting into. (If you give it a number of stars, be sure to indicate out of how many possible, so we know your scale.)
Liked a book you borrowed? Flip back into the guest book to see who made the donation and write in a thank you to the donor.
Have a book you’ve been longing for? Write it in and maybe a fellow neighbor has a copy they can donate on a future visit.
Visiting our branch from far away? Be sure to write down your hometown and country so we know how far away our books travel.
Maybe you’re waxing poetic when stopping by? Feel free to write a short poem or haiku about our library.
Wish List
Our wish list has two functions:
Write down any books you’d love to see come to our library so you can borrow them in the future.
Read the list to see if you have any of the books you might donate so that others can enjoy them.
A Tiny Library with Its Own Social Media
To help support the neighborhood library (in the digital age every library needs a blog right?), I’ve created a website for it at: http://lfl8424.boffosocko.com/. The site has a variety of resources relating to our branch. For those that prefer to follow and interact with the content via social media, there are also the following:
GoodReads: Books currently on our bookshelf (updated regularly – hey, we live on a pretty big hill and walking up to see what’s on tap can be torture, especially in 80+ degree heat)
For those interested in my particular process, here’s how I did it.
Recently I saw something a bit more quirky and interesting than my original plans that I could up-cycle, so I made the purchase (happy belated birthday to me)! It was a nice little metal newsstand that Cost Plus World Market had put on clearance as they’re no longer going to carry it. The last one the store had was a bit dinged up and had some scratches, so I negotiated an additional discount. It’s got two spacious shelves with two doors including a glass fronted one, and it’s got the capacity for at least 6 linear feet of books.
A trip to the hardware store for a small sheet of plywood, an 8′ post, and some wood screws, machine screws and nuts finished up the material needs. I cut the post down to 54″ and cut the plywood down to fit underneath the newsstand. I pre-drilled some small holes in the plywood to screw the plywood down onto the post. Then I drilled holes into the bottom of the newsstand and fit it down on top of the plywood and attached with the screws and nuts.
Parts and hardware for building my Little Free Library
I posted a note on Nextdoor.com and within just minutes had an offer from two neighbors to loan me a post hole digger. (Thanks Rob and Scott!) The following day the 2 foot hole was open and the library was planted. (And I returned the post hole digger to Rob.)
Following this, I dug up a handful of seeder books, registered them with BookCrossing.com and put them on a GoodReads.com shelf, and put them into the library. We’ve technically been open for a week and without any publicity at all, we’ve had over a dozen books flow through the library already.
Total cost out the door: just under $200.

The second in an occasional look at the technology I use regularly
F
riends, family and colleagues are frequently asking my advice on what kind of devices and software I find most useful. So following in the tradition of Bernard Pivot and subsequently the Actor’s Studio, and sites like LifeHacker, Supersite for Windows, and many others, I’ve borrowed a handful of standard “get-to-know-you” type of questions that others might find helpful.
Keep in mind that given an infinite budget, I’d have quite a bit more or possibly be using something slightly different or more recent, but the following are things I actually use on an almost daily basis. I also have a large handful of occasional devices and tricks that are not included in the list for brevity.
Fifty years from now, this list should also be fairly entertaining to reread. The first installment of the series can be found here: What I Use: April 2014. It includes some additional sections and material that hasn’t changed since then.
Primary equipment
Mobile device
Samsung Galaxy S6 on Sprint – I’ve had this for a couple of months now and like it a lot, but I honestly feel like there hasn’t been anything really new or exciting in the phone space for a while. Phones are becoming commodity items.
Computer
Lenovo Flex3 – I’ve had it for a couple of months and love its size, weight, and the fact that I can flip it over into a tablet. I’m still occasionally using my Lenovo Thinkpad Edge E431, but planning on decommissioning it shortly.
Operating system(s)
I am using the final, shipping professional version of Windows 8.1 with Update 1 on my primary laptop PC. Windows 10 is starting to roll out, and I’m about to make the jump…
I still have a multi-boot set up on a 10″ Asus EeePC with XP, Windows 7, JoliOS (flavor of Linux), and a multi-boot set up on an HP desktop with XP, Vista, Windows 7, and the latest Ubuntu Linux, but I’ve rarely used them in the last year.
Productivity
I made the jump to Office 365 Home Premium about a year ago and generally love it, particularly being able to dump almost everything I have into the cloud via OneDrive with a 1+TB storage option. For the bulk of my writing though, I still eschew Word and use WinEdt as a text editor/user interface in combination with a MiKTeX installation and Adobe Acrobat to typeset in LaTeX – the output is simply glorious. I’ve actually been doing the typesetting and layout for a client’s novel with this set up over the past few months, and it is truly great despite having do dig under the hood a bit more than I’d prefer to get the exact results I want.
Since my last “What I’m Using” I’ve moved away from Dropbox as my primary cloud service and prefer OneDrive for syncing across multiple platforms. I still have a huge amount in Dropbox and still use it for some collaboration. For email, contacts, and calendar management, I primarily use Outlook, though for some collaborative work, I have been using Google’s Calendar a lot more in the last year particularly for its simple integration into my phone. I also have a well-exercised Gmail account for sifting most of my social media accounts, as well as a lot of bacon and spam. I have gone through lately and cut the number of notifications I get by email in half. For reading Gmail, I primarily use Googles Inbox app on my cell phone when I’m waiting in lines.
Internet and communications
For web browsing, I use the latest version of Google Chrome typically to the exclusion of all others. For instant messaging and video chat I use either Skype or Google Hangouts depending on the others involved, though I generally prefer Hangouts.
I obviously use WordPress, but also have a few sites running Drupal as well. Over the past year, I’ve become a big proponent of the IndieWeb movement which fits in line with my long held beliefs about personal data. Toward this end, I’ve added a lot of IndieWeb plugins to my WordPress workflow, and I also love WithKnown which I use as my primary social stream tool. It dovetails with most major social networks incredibly well.
I do not use any third party security software as Windows Defender in Windows 8.1 includes anti-virus functionality and this seems to be more than enough. I tried a free trial of McAfee with my Flex3, but it was awfully bulky and annoying and the UI was just dreadful. Generally just not clicking on any links you aren’t 100% certain are secure will cover most problems with viruses and malware.
Digital media
Music: I rarely, if ever, purchase music online or otherwise; I’m also not currently subscribing to any online delivery systems. For the last year, I’ve been using Spotify to the exclusion of almost all others, though I still visit Pandora, Google Music, and Amazon Music depending on my location and needs. Most of my owned music, audiobooks, and video content is managed through iTunes. I use DoubleTwist to sync my iTunes playlists and music to my Android devices. I sporadically use XM/Sirius in the car, but can’t bear to spend more than about $4 a month on such service when there are so many alternatives. I’m currently on an XM/Sirius hiatus, but I do miss the clarity and the dedicated bluegrass station.
Video: Netflix is the primary video service I use on an almost daily basis, though Amazon Prime’s streaming services is a fairly close second. Given the general availability of the content I want to watch, I find it rare to need to purchase any video content on any other platforms. I don’t often rip DVD’s, but when I do, I love Handbrake, which seems to be the sine qua non in the area. I spend a lot more time using my Lenovo Flex3 for Netflix with my Chromecast a close second.
Books: I have such a complicated set up with regard to ebooks, it will take an entire post to cover it all. In simplest terms, I manage everything through a well-integrated combination of Calibre, Goodreads.com, Amazon’s Kindle, Adobe Digital Editions, Adobe Acrobat Reader, DJView, and OneDrive. Most books I get are either purchased through Amazon or are borrowed from a litany of local public libraries. I’ve spent the last several years converting almost all the reading I do to electronic reading. I still prefer to read on paper, but the overall process is much simpler in digital. Most technical books I read within some version of Adobe Acrobat for its ability to highlight, comment, and create notes. For most of the last year, a lot of my pleasure/fiction reading has been done via the BaltoReader app on my Amazon Kindle 7″ which allows me to read at greatly increased speeds. (I covered it and some other options here: Speed Reading on the Web and Mobile.
Audiobooks: I’ve loved Audible.com for a long time, but I’m still on a hiatus from it playing catch up on some of the content I’ve accumulated over the past couple of years. It’s an awesome service. I also often use the Overdrive service through several local libraries for downloading and listening to audiobooks. While Overdrive is clunky and smothered in DRM, it works and is just good enough, and I’ve yet to find anything better that is free. When necessary, I’ll also borrow CD’s from the local library for listening as well.
Photos: I still do a horrible job of managing my thousands of photos. In line with a general switch to OneDrive, I autoback up my photos from my phone there, but still also prefer to use Google+ photos. I will admit that some recent changes to Flickr make me want to reconsider it for broader use, but I’m not all in just yet.
My favorites and most often used include: DoubleTwist, Waze, WithKnown, Google Hangouts, Google Voice, Amazon Kindle, BaltoReader, Facebook, Google Inbox, Pocket, Netflix, Instagram, Starbucks, Key Ring, Shazam, S Health, Periscope, Flipboard and less frequently Audible and OverDrive Media. The notable new entries in the last year are the “Do Suite” from IFTTT.com including Do Camera, Do Note, and somewhat less frequently Do Button. I use these several times a day and they’re front and center on my phone now. I also love IFTTT for a variety of back-end integrations for various other web technologies.
There are certainly others, but I rarely use many of them and didn’t reinstall many when I upgraded phone in June.
In the last year, I’ve moved away from Evernote in favor of OneNote which provides better integration to my Outlook workflow, but I will admit I do miss the UI of Evernote.
Home technology
Television
I’m still using a Samsung Series 5, 40″ LCD flatscreen. Though there are certainly much newer models out there, this really has everything I could want and supplies a fantastic picture as well as even native sound. Until the mansion arrives, or California housing prices drop precipitously, this is probably more television than I even need. For service I only use DirecTV which, though I desperately love, I have a feeling I’ll eventually dump it to live a complete cord-cutter life.
Set-top boxes
In addition to a DirectTV HD DVR which I upgraded last fall to a newer model with 1TB storage , I also have a Roku XD|S and Google Chomecast. The Chromecast gets far more regular use, particularly for Netflix integration (via either a tablet or cell phone) and in my mind is the clear winner for being drop-dead easy-to-use. I particularly love the fact that the Chromecast automatically turns on the television and changes the internal television tuner, so I don’t need to pick up other devices to control the television. The Roku is ancient and clunky and now doesn’t support a lot of the newer apps/channels. I get regular emails from Roku about discounts for upgrading, but I’m not sure I use it enough or that the upgrades are worth replacing it. I rarely use the mini-HDMI to HDMI adapter to connect my Kindle Fire HD to the television for streaming Amazon Prime video to the television these days.
Kitchen
Cambro Containers: Over the last year, I’ve gotten a dozen large Cambro containers ranging from 2qt-8qt for more easily storing bulk goods like flour, sugar, rice, beans, etc. They store much more easily and functionally in the kitchen and the fridgerator. I don’t know how I lived without them before.
Scraper: Almost a year ago, I got an OXO Good Grips Jar Spatula, White and it has been my single-most used kitchen item after my knife since. For size, shape, and sheer versatility it’s one of my favorite tools. I’m tempted to get rid of all of my other scrapers and buy 4 more of these.
Coffee: I’m not a total fiend in this department and usually prefer soda or tea, but when necessary, a simple Bodum French press in combination with a Kitchen Aide coffee grinder are just great. I’m still very tempted to get the relatively inexpensive Aerobie AeroPress…
Mixer: Life wouldn’t be complete without my 325 Watt Artisan Kitchen Aide stand mixer with a handful of attachments.
Scale: I believe Fannie Farmer irreparably destroyed much of what could have been some superb American cuisine and any semblance of science in the kitchen, so I avidly use my Salter 3003 Aquatronic Glass Electronic Kitchen Scale to begin the healing.
What apps/software/tools can’t you live without? Why?
In a year, nothing here has changed. I simply love these:
Calibre – For my 2000+ ebooks, this is an indispensable e-book and document program that is to books as iTunes is to music. I also use it to download dozens of magazines and newspapers on a daily basis for reading on my Kindle. I love that it’s under constant development with weekly updates for improved functionality.
Waze – When living in Los Angeles, this real-time traffic application often saves me anywhere from 30-90 minutes of time in traffic a day; it also has the side benefit of helping you explore parts of the city you might not find otherwise.
DoubleTwist – Since I’m an avid Android fan, I use this simple app to dovetail my music and video collections in iTunes to sync with my other digital devices.
What’s your workspace setup like?
For the past couple of years I’ve been using a 1962 McDowell & Craig executive tanker desk that I refinished in 2008 and I use a matching chair which I painstakingly reupholstered by hand in late 2013. I often use the custom made glass top with dry-erase markers to sketch out ideas or write disposable notes and also place photos and incunabula of various sorts underneath it. I’ve been tempted to do a standing desk but as yet haven’t. I’m half tempted to follow the lead of film editor Walter Murch and set my desk up on cinder blocks to jack it up to waist level.
What’s your best time-saving/shortcut/life hack?
A combination of Feedly, Pocket, and the Spritz Bookmarklet on my computer allows me to plow through way more reading material that I used to be able to before.
What’s your favorite to-do list manager?
I primarily use a very customized version of Outlook and its task functionality to track my to do list items. I use OneNote as my commonplace book particularly as it has a bookmarklet that makes it dead easy to transfer data into it.
Besides your phone and computer, what gadget(s) can’t you live without and why?
For education purposes (primarily lectures), I am absolutely in love with my Livescribe Pulse Pen. I own three different versions. Every student on the planet should have one.
For a while now, I’ve been catching up on the mid-70’s music I missed in my early youth. I’m still exploring 60’s Jazz and classic bluegrass.
What are you currently reading?
Generally I’m actively reading 4-5 books at a time and less-actively up to 15 or so. I use Goodreads.com to manage my reading lists, to find recommendations from others, and in part to catalog my library (though I’m far from having everything I own there). I usually tend toward non-fiction, science, math, history and biography when reading for pleasure, though the occasional fiction piece will work its way into the stack.
Lately I’m regularly watching Hannibal, Mr. Robot, Murder in the First, Charlie Rose, Suits, Royal Pains, The Closer (early season reruns), PBS News Hour, Major Crimes, and The Profit. Guilty pleasure watching includes Shark Tank, Last Comic Standing, America’s Got Talent, UnREAL, and solely because there’s a “Chris Aldrich” on the show, I’ve seen a few episodes of season 2 of VH1’s Dating Naked. When they return I’ll still be watching Modern Family, The Big Bang, Person of Interest, and Grimm. Relatively recent binge watches include Mad Men (final 3 seasons) and House of Cards (season 3).
Bernard Pivo-esque section
What everyday thing are you better at than everyone else? What’s your secret?
I have a generally better memory than most. Though it was naturally good when I was younger, I ran across the concepts of the major system and the method of loci (aka the memory palace) at an early age and they have helped significantly.
What’s your sleep routine like?
I never seem to sleep as much as most, but lately I’ve been getting 7-8 hours of sleep at night usually from 12-7am. I’m far from a morning person and most of my best thinking hours are from 11pm to 2am.
Are you more of an introvert or an extrovert?
I grew up definitely as an introvert, but during college I managed to force myself to be an extrovert. These days I move between the two as my mood and social circumstances dictate.
What’s the best advice you’ve ever received?
Some know it as the “Golden Rule,” but “Treat other people like you want to be treated.” I highly recommend people read How to Win Friends and Influence People.
Like a kid anxiously awaiting Christmas morning, I spent some time refreshing UCLA Extension’s web page over the weekend in hopes of seeing the announcement of Mike Miller’s Fall math course with no results.
I checked again a half hour ago and their site was down!
My salivating hit a fever pitch!
Refreshing, refreshing, refreshing… and now it’s live again with:

Algebraic Number Theory
MATH X 450.8 | 3.00 units
In no field of mathematics is there such an irresistible fascination as in the theory of numbers. This course, the first in a two-quarter sequence, is an introductory, yet rigorous, survey of algebraic number theory, which evolved historically through attempts to prove Fermat’s Last Theorem. Beginning with a quick review of primality and unique factorization for ordinary integers, the course extends these notions to more exotic domains: quadratic, cubic, cyclotomic, and general number fields. This development is then applied to the representation of integers as sums of squares and, more generally, to classic Diophantine equations. Topics to be discussed include: Euclidean, principal ideal, and Noetherian domains; integral bases; binary quadratic forms; algebraic field extensions; and several remarkable theorems/conjectures of Ramanujan.

A Note For the Reticent
Exercise Your Brain
As many may know or have already heard, Dr. Mike Miller, a retired mathematician from RAND and long-time math professor at UCLA, has been offering incredibly inexpensive upper level undergraduate and graduate level math courses for 30+ years through UCLA Extension.
Whether you’re a professional mathematician, engineer, physicist, physician, or simply a hobbyist interested in mathematics you’ll be sure to get something interesting out of this course, not to mention the camaraderie of 20-30 other “regulars” with widely varying backgrounds (actors to surgeons and evolutionary theorists to engineers) who’ve been taking almost everything Mike has offered over the years. Once most new students have taken one class, they’re incredibly prone to want to take them all (and yes, he’s THAT good — we’re sure you’ll be addicted too.)
“Beginners” Welcome!
Even if it’s been years since you last took calculus or linear algebra, Mike (and usually the rest of the class) will help you get quickly back up to speed to delve into what is often a very deep subject. Though there are a handful who will want to learn the subject for specific applications, naturally, it’s simply a beautiful and elegant subject for those who just want to meander their way through higher mathematics for the fun of it (this will probably comprise the largest majority of the class by the way.)
Whether you’ve been away from serious math for decades or use it every day or even if you’ve never gone past calculus, this is bound to be the most entertaining thing you can do with your Tuesday nights in the fall. If you’re not sure what you’re getting into (or are scared a bit by the course description), I highly encourage to come and join us for at least the first class before you pass up on the opportunity – there’s no need to preregister or prepay if you’re unsure. I’ll mention that the greater majority of new students to Mike’s classes join the ever-growing group of regulars who take almost everything he teaches subsequently.
For the reticent, I’ll mention that one of the first courses I took from Mike was Algebraic Topology which generally requires a few semesters of Abstract Algebra and a semester of Topology as prerequisites. I’d taken neither of these prerequisites, but due to Mike’s excellent lecture style and desire to make everything comprehensible to the broadest number of students, I was able to do exceedingly well in the course. Also keep in mind that you can register to take the class for a grade, pass/fail, or even no grade at all to suit your needs/lifestyle.
My classes have the full spectrum of students from the most serious to the hobbyist to those who are in it for the entertainment and ‘just enjoy watching it all go by.’
Mike Miller, Ph.D.
Textbook: Introductory Algebraic Number Theory
Update (8/19/15) Per my email conversation with Dr. Miller, despite that neither the Extension website nor the bookstore have a book listed for the class yet, he’s going to be recommending Introductory Algebraic Number Theory by Saban Alaca and Kenneth S. Williams (Cambridge University Press, 2003, ISBN: 978-0521183048).
I’ve just recently finished the excellent book Why Information Grows by César Hidalgo. I hope to post a reasonable review soon, but the ideas in it are truly excellent and fit into a thesis I’ve been working on for a while. For those interested, he does a reasonable synopsis of some of his thought in the talk he gave the the RSA recently, the video can be found below.
The underlying mathematics of what he’s discussing are fantastic (though he doesn’t go into them in his book), but the overarching implications of his ideas with relation to the future of humankind as a function of our economic system and society could have some significant impact.
“César visits the RSA to present a new view of the relationship between individual and collective knowledge, linking information theory, economics and biology to explain the deep evolution of social and economic systems.
In a radical rethink of what an economy is, one of WIRED magazine’s 50 People Who Could Change the World, César Hidalgo argues that it is the measure of a nation’s cultural complexity – the nexus of people, ideas and invention – rather than its GDP or per-capita income, that explains the success or failure of its economic performance. To understand the growth of economies, Hidalgo argues, we first need to understand the growth of order itself.”
It also not coincidentally is the root of the vast majority of the problems the world is currently facing. There are so many great quotes here, I can’t pick a favorite, so I’ll highlight the same one Kimb Quark did that brought my attention to it:
“There’s nothing wrong with an opinion on those things. The problem comes from people whose opinions are actually misconceptions. If you think vaccines cause autism you are expressing something factually wrong, not an opinion. The fact that you may still believe that vaccines cause autism does not move your misconception into the realm of valid opinion. Nor does the fact that many other share this opinion give it any more validity.”
“A fragmention is an extension to URL syntax that links and cites a phrase within a document by using a URL fragment consisting of the phrase itself, including whitespace.”
To take advantage of the functionality, append a # and the text you’d like to highlight on the particular page after the address of the particular web page. Add a + to indicate whitespaces if necessary, though typically including a single, unique keyword is typically sufficient to highlight the appropriate section.
“One of the wonderful features of math is that, like with pastry, it can use quite simple ingredients to make very complicated situations. This can also make it rather offputting, like making puff pastry. Actually, I don’t think puff pastry is that difficult if you follow the instructions carefully. But even if you don’t want to try doing it yourself, perhaps you can still enjoy the fact that such simple ingredients can turn into delicious puff pastry. Math is about understanding processes and not just eating end results.”
ver the past couple of months leading up to to the launch of VH1’s new season of “Dating Naked: Playing for Keeps” , I’ve been entertained by friends who have seen little snippets and notices about the show and wondering why and how I got involved in front of the camera. Honestly, it’s mostly been the why question. Ego-bruisingly, only one so far has wanted to know if they could get the “unblurred” cut of the show.
Let’s get one thing straight: the Chris Aldrich on VH1’s Dating Naked is NOT me — first of all, I’m way better looking.
Fortunately as we’re getting closer, there’s now “artwork” to support the fact that it’s not me.
Once the show launches on the 22nd, I almost can’t wait to see what happens to the Google ranking for my searches on my name. I’m sure I’ll have some further entertainment in relation to my twitter account @chrisaldrich and other parts of my social media presence. I’m almost tempted to make a few changes in the bio sections to increase the ambiguity and cause some trouble.
I’m reminded of Wes Moore’s book “The Other Wes Moore: One Name, Two Fates“, unfortunately I’m not quite sure that my writing a book about my experience with “The Other Chris Aldrich” would be so uplifting or inspiring to others. I’d also be more worried that I’d have to change the subtitle to “One name, One Fate.”
Almost the same moment I saw my first Little Free Library, I decided that I wanted to host one of my very own, so I registered with the intent of building one in my free time. The registration arrived and I’d drafted some very serious custom plans, but just never gotten around to purchasing the supplies and building it.
Recently I saw something a bit more quirky and interesting than my original plans that I could up-cycle, so I made the purchase (happy belated birthday to me)! It’s got two spacious shelves with two doors including a glass fronted one, and it’s got the capacity for at least 6 linear feet of books. We’re nearly ready to go.
I’m hoping to get some mounting materials and have the library up and running soon. My plan is to specialize in literary fiction, though I’m sure we’ll also stock a fair amount of popular science and non-fiction as well as thriller, mystery, and suspense as well.
Invitations to the “launch” party should be coming shortly! If you’ve got some books you’d like to donate toward the cause, let me know in the comments below. Be sure to include a Book Crossing ID number on them if you’d like to track where your favorite objects head off to in the future.
The Golden Rule mandating that you treat others as you want them to treat you is simply a variation on tit-for-tat, one that emphasizes the benefit rather than the harm side. (The Christian principle of returning a favor for a harm in this respect is highly unusual and, one might note, more often than not unimplemented in Christian societies. No society I know of approves returning a harm for a favor as a general moral rule within the group.)
[recipe title=”Cream Scones” servings=”6-8″ time=”25-30mins” difficulty=”easy” image=”http://boffosocko.com/wp-content/uploads/2015/07/20150704_100549.jpg” description=”Light, flaky classic scones with full flavor”]
[recipe-ingredients]
– flour (all purpose generally yields better results than cake)
– sugar
– baking powder
– salt
– unsalted butter (cold)
– fruit: usually dried currants, raisins, chocolate chips, or other fruit
– egg
– heavy cream
– fruit zest (orange, lemon, grapefruit, other)
– cinnamon
[/recipe-ingredients]
[recipe-notes]
Other fats could be substituted for the butter, but butter generally tastes best here. For the small handful of health conscious non-professional home cooks, absolutely do not substitute milk for the cream, otherwise the fat ratio for the recipe will be thrown completely off and your results will be horrifying.
Ratio
5 parts flour : 1 part sugar : 1.5 parts butter : 1 parts egg : 2 parts cream : 1.5 parts fruit
Other ingredients (approximately per part)
1/2 teaspoon salt per part
1 tablespoon baking powder
1/4 oz zest
Professional kitchens scaling the recipe beyond 75 oz of flour, may wish to use 1.25 parts of sugar for more even results.
[/recipe-notes]
[recipe-directions]
1. Preheat oven to 425° F.
2. Whisk together the flour, sugar, baking powder and salt until mixed thoroughly.
3. Cut the cold butter into the flour mixture with a pastry blender until the lumps of butter are just larger than the size of a pea. Any smaller and the scones will be tougher and less flaky.
4. Mix together the cream, egg, (optional currants, raisins, fruit), and the zest, then mix into the flour/butter just until the dough comes together.
5. Do not overwork the scone dough or the resultant scones will not be light and flaky. You should preferably be able to still see small chunks of butter in the dough.
6. Roll the dough out into a disk about 1.5″ thick.
7. Brush a light layer of cream (or milk) onto the top of the disk and sprinkle on a nice layer of cinnamon and sugar.
8. Using a dough scraper cut the dough into eight equal wedges and place onto cooking sheet.
9. Put the sheet of scone dough into the oven at 450 for 12-15 minutes until golden brown, or until an inserted toothpick comes out clean.
10. Cool for a few minutes and then enjoy fresh with clotted cream and fresh fruit.

I have to imagine that once the conceptualization of language and some basic grammar existed, word generation was a much more common thing than it is now. It’s only been since the time of Noah Webster that humans have been actively standardizing things like spelling. If we can use Papua New Guinea as a model of pre-agrarian society and consider that almost 12% of extant languages on the Earth are spoken in an area about the size of Texas (and with about 1/5th the population of Texas too), then modern societies are actually severely limiting language (creation, growth, diversity, creativity, etc.) [cross reference: A World of Languages – and How Many Speak Them (Infographic)]
Consider that the current extinction of languages is about one every 14 weeks, which puts us on a course to loose about half of the 7,100 languages on the planet right now before the end of the century. Collective learning has potentially been growing at the expense of a shrinking body of diverse language! In the paper “Global distribution and drivers of language extinction risk” the authors indicate that of all the variables tested, economic growth was most strongly linked to language loss.
To help put this exercise into perspective, we can look at the corpus of extant written Latin (a technically dead language):
“It is a truly impressive fact that, simply by knowing that if one can memorize and master about 250 words in Latin, it will allow them to read and understand 50% of most written Latin. Further, knowledge of 1,500 Latin words will put one at the 80% level of vocabulary mastery for most texts. Mastering even a very small list of vocabulary allows one to read a large variety of texts very comfortably.”
These numbers become even smaller when considering ancient Greek texts.
Another interesting measurement is the vocabulary of a modern 2 year old who typically has a 50-75 word vocabulary while a 4 year old has 250-500 words, which is about the level of the exercise.
As a contrast, consider the message in this TED Youth Talk from last year by Erin McKean, which students should be able to relate to:
[ted id=2158]
And of course, there’s the dog Chaser, which 60 minutes recently reported has a vocabulary of over 1,000 words. (Are we now destroying variants of “dog language” for English too?!)
Hopefully the evolutionary value of the loss of the multiple languages will be more than balanced out by the power of collective learning in the long run.
For those who are intimidated by the thought of higher mathematics, but are still considering joining our Category Theory Summer Study Group, I’ve just come across a lovely new book by Eugenia Cheng entitled How to Bake Pi: An Edible Exploration of the Mathematics of Mathematics.
Eugenia Cheng’s book How to Bake Pi
It just came out in the U.S. market on May 5, 2015, so it’s very new in the market. My guess is that even those who aren’t intimidated will get a lot out of it as well. A brief description of the book follows:
“What is math? How exactly does it work? And what do three siblings trying to share a cake have to do with it? In How to Bake Pi, math professor Eugenia Cheng provides an accessible introduction to the logic and beauty of mathematics, powered, unexpectedly, by insights from the kitchen: we learn, for example, how the béchamel in a lasagna can be a lot like the number 5, and why making a good custard proves that math is easy but life is hard. Of course, it’s not all cooking; we’ll also run the New York and Chicago marathons, pay visits to Cinderella and Lewis Carroll, and even get to the bottom of a tomato’s identity as a vegetable. This is not the math of our high school classes: mathematics, Cheng shows us, is less about numbers and formulas and more about how we know, believe, and understand anything, including whether our brother took too much cake.
At the heart of How to Bake Pi is Cheng’s work on category theory—a cutting-edge “mathematics of mathematics.” Cheng combines her theory work with her enthusiasm for cooking both to shed new light on the fundamentals of mathematics and to give readers a tour of a vast territory no popular book on math has explored before. Lively, funny, and clear, How to Bake Pi will dazzle the initiated while amusing and enlightening even the most hardened math-phobe.”
Dr. Cheng recently appeared on NPR’s Science Friday with Ira Flatow to discuss her book. You can listen to the interview below. Most of the interview is about her new book. Specific discussion of category theory begins about 14 minutes into the conversation.
