Simplicity 4767 one more time

Sewists compete for how fast they can sew up the fabric they purchased at PR weekends. I would come in dead last because I bought about 6 months worth of fabric at my usual pace. ;-)  Yesterday, I sewed up the first piece.

I found this Liberty Tana Lawn remnant at Britex and thought it would make a sweet little girl's dress. My girl is not so little, so this one is heading over to PhysicsKnits because her little girl just became a big sister.

I used Simplicity 4767 again.  This is View A in a size 3.  Because Tana Lawn can be a bit sheer, and I wanted the dress to be wearable in public, I lined the body with gray cotton voile.  Of course, everything is clean finished with flat-felled and/or enclosed seams for hand-me-down quality.

Peasant blouses offer much "bang for the buck"(time) because they are relatively easy to sew and wear.  Take extra care with the seams so that they don't chafe tender young skin. They will be worn right out of the laundry and never see the inside of a closet.

Iris and her cousin have 8 blouses/nightgowns and one pair of PJ pants made from this pattern.

Boiling over

Sometimes, it's not so thrilling to nail a forecast.

NOAA scientists predicted that the areas in the red boxes would experience tornadoes and the areas in the yellow boxes might experience tornadoes.  In preparation, geostationary weather satellites (the G in GOES stands for geostationary) were put in Super Rapid Scan* mode so that they could send down higher-resolution data in both spatial and temporal scales.

Hopefully, the faster scan and downlink rates bought people time to scramble to shelters and kept the casualty rates lower than they would have been without the precious few extra minutes of  warning.


Even though Scott Bachmier of the CIMSS Satellite Blog has been sequestered, his boss found some money to keep him blogging for public education.  He put together this incredible animation of Oklahoma on May 18, showing "overshooting" cloud tops.  In plain English, air parcels were tossed upwards with such tremendous force, their momentum carried them up above their thermodynamic stability level.  Watch this stereo animation.  The clouds literally boil over.



The animation for May 20 is similarly impressive.  In addition to the boiling behavior, look at the lines of waves emanating from the frontal region and extending to the southeast (bottom right) corners of the images.
That line of L's in the top color picture from Unisys (based on NOAA/NCEP predictions) stands for low pressure. That trough of low pressure is expected to remain stationary for several days and will continue to draw in warm, moist air from the gulf of Mexico--and generate tornadoes where they collide.

Imagine living through the devastation of the past three days in Oklahoma and knowing that you face three or more days of this.  How are you going to soothe your kids while not downplaying the very real danger?

USA Today put together a graphic overlay of the May 3, 1999 and May 20, 2013 tornadoes.

Is it just my imagination, or can you still see some of the scars of the 1999 tornado on the satellite image on this Google Map of Oklahoma tornado sites?


Perpetual drought and longer fire seasons in the southwest, longer tornado seasons in the midwest, longer hurricane seasons and more intense hurricanes in the southeast, and more nor'easter meets subtropical jet mega-snowstorms in the northeast are all signatures of a warming planet.  The physics of how a warmer overall global climate leads to an increase in the probability of these events is well understood.

* Animations such as these are possible only because images are scanned and beamed to earth every ~5 minutes.  Thus, each frame is taken about 5 minutes apart.  With satellite bandwidth, you have to rob Peter to pay Paul.  Imagery in the southern hemisphere was probably sacrificed for this.

When you think about it, it's incredible that photons fall on a detector out in space and then we get movies like this a little while later.

Forget STEM, I'm on team STEAM

Project H Design wrote:
Integrating science, technology, engineering, arts, and math (STEAM) skills, Studio G projects build confidence, grit, and the belief that everything is possible in life and in the world.
That's exactly what I think has been missing in the entire STEM debate, an explicit recognition that creativity is an integral part of design and problem-solving in all fields.

This gives a whole new meaning to STEAMpunk.

High school students in Bertie County (NC) designed and built this farm stand.  Read more about the program and how the hostility from NC school officials has driven Project H out of NC to more friendly Berkeley, CA.

In other news, our local schools have just completed STAR testing.  How about your local districts?

I've been thinking about the point of STAR testing and how it has been perverted/subverted over the years.  I am so glad that this is the last year our state has to go through this farce.  But, I don't know how the common core will be implemented.

MMM ThemeFriday Hat

I got my themes mixed up and did NOT take a photo with a hat this year.  Instead, I will recycle content from What would Rachel wear?, a dress from recycled elements.


This might be cheating, but new readers may be interested in the link because I scanned and showed a vintage BWOF magazine from 1995.

Next week, I'll be ahead of the game with the photos that we took yesterday.  Myrna will have to wait for her photos of a scarf from recycled jersey scraps.

Comic book plot element

Iris told me that gamma rays have been done to death and she is going to use beta decay in the comic book she is writing.

Which led us to discussing, not just the electron-antineutrino pair that appears in neutron decay, but also the positron-neutrino pairs that can also result.  Her ears pricked up.

"Are they anti-matter?  How do they hold it?"

Umm, it's late and you should get to bed.

Why don't you ask your grandfather his war stories of delivering enough juice to power a Tokamak without browning out the entire surrounding region?

Some other time, I will tell you the story of how I raised my hand in graduate quantum class and asked the professor where in the periodic table do I find positronium.  (I have a BS in Chemistry and have never seen positronium in a periodic table of elements.  Have you?)

Anyway, the class erupted in laughter and I had no idea why.  Absolute horror--nightmare where you show up to class without clothes type moment.

On the bright side, this could be a good plot element for her heroine.

BTW, what is the difference between a comic book and a graphic novel?

Topological Oops

I had a momentary topological lapse when seaming my version of Norah Gaughan's Nespelem Cardigan. Can you tell what I did wrong?

It took 45 minutes with an audiobook to fix it.

NG's patterns are so well thought-out. Look at the way the sleeve echoes the details of the back and collar.

I learned something truly awful (and yet also exciting) in CopyrightX. Patterns are expressions of facts. So patterns themselves are NOT copyrightable, but the ways that they are expressed are protectable.
So photocopying a pattern to give to a friend is not allowed, but telling a friend how many stitches to cast on is legal.

That pattern facts are not protectable may be economically harmful to their authors, but it also allows others to build upon their work and move the state of the art forward. The fact that patterns are not protectable may contribute to the vibrancy of fashion arts. Food for thought.

Required reading about MOOCs


Commentator Douglas Kretzman left two excellent links.   The MOOC Moment and the End of Reform By Aaron Bady is the best discussion of what MOOCs means for education in particular and society in general I have ever read. It is truly not to be missed.

Then read this tongue in cheek but deadly serious CUCFA President Meister's Open Letter to Coursera Founder Daphne Koller.

The California Master Plan is in tatters.  I could go on and on about how the promise is illusory and about the craven cynicism of the people who pretend that it still exists other than on paper.  I want to be part of the group who push back against privatization of education.

Thank-you so much for the links DK!

The CopyrightX model of online education is not scalable.  It depended on TAs that (as far as I could tell) volunteered their time in order to gain experience and teaching experience for their resumes.  It also piggy-backed upon a class happening in real time on campus at HLS and the technological assistance and platform provided by edX.

Mostly, the experience depended on a small group of students capable of surpassing hurdles such as admissions essays.  At the end of the class, we posted our LinkedIn profiles and added each other to our networks.  It turns out that nearly all of my North American counterparts had already graduated from elite universities for either undergrad or grad school (or both).  One cannot responsibly extrapolate the data from this online learning experiment to educating under-served communities.

Notes from a RCT guinea pig

I hope you all had a wonderful mothers' day.  I opened mothers' day while madly writing responses to  questions for a CopyrightX final exam.  Bad Dad went to Trader Joe's for a food run and brought me some flowers to liven up the computer desk and chocolates for caffeine and energy.

Much has been written about MOOCs, massive open online classes, but mostly by nontechnical writers.  I think that MOOCs can be wonderful for computer programming courses.  But, they are lacking for humanities and other open-ended disciplines.  If reporters only sample the nontechnical MOOCs, then they will come away with the impression that MOOCs are just an educational fad with no real substance behind it.

Nathan Heller's long article for the New Yorker,  Laptop U, is representative of the coverage Bad Dad and I have read.  He opens with The Ancient Greek Hero, a class that Bad Dad is taking very seriously and I have all but given up on, and closes with CopyrightX, a very rigorous class I just completed.

CopyrightX is not a MOOC in the sense that it is not truly open.  Potential students apply and are selected.  I'll refer to it as a MOC, though, at 500 students, it's neither open nor massive.

We also pledge that, if selected, we will put in at least 8 hours a week of study and discussion time.  To further weed out dilettantes, the online application included several essay questions about our backgrounds and motivations for studying copyright.  I wrote about my past work in data collection and curation and my sewing and blogging hobbies.  My answers were compelling enough to land me one of the 500 internet student slots.

Heller wrote: "In picking students, [professor Terry Fisher] looked partly for a range of ages and professions: his goal is to seed knowledge of digital-age copyright law among people who will apply it creatively in their own circles and work."

 Of the 25 people in my section, three held PhDs, one two were practicing IP attorneys and a handful worked as librarians and archivists for a range of federal and state agencies or nonprofits. This was not your average (wo)man on the street cohort.  Students came from Europe, North and South America and China, but the North American and European students were most active in discussion boards and at the "live" weekly recitation sections.  I'm curious to learn how many of us took the final (which is a proxy for sticking it out in the class).

In addition to the weekly lectures by the professor, we read review articles and case law, "met" with our section for weekly discussion with our TA as a moderator and watched biweekly guest lectures.  Our TA also offered weekly office hours and sent out additional study materials throughout the weeks. If we asked a question that our TA couldn't answer, she sent it out to her fellow TAs and the professor and replies rolled in reasonably quickly.

Functionally, CopyrightX was a small college seminar, taught by a graduate teaching assistant and overseen by a rock-star professor.  The TA was super generous with her time.  The professor, though not approachable directly by students, spent considerable time preparing the class and listening to the TAs and the students through the TAs.

The internet 500 (CopyrightX group) took the class at the same time as students enrolled in the bricks and mortars Harvard Law School (HLS), studying the same units at the same pace.  In discussion section, HLS and CopyrightX students discussed the same "hypotheticals", or hypothetical cases.  During the special guest seminars, both HLS and CopyrightX students could submit questions.  Other students and TAs would upvote questions on the board, and the guests answered the top-voted questions from both groups.

The CopyrightX welcome message mentioned that we were assigned to one of four groups.  I instantly wrote my teaching assistant to ask if we were taking part in a randomized clinical trial (RCT).  (I learned about RCTs in PH207x Health in Numbers: Quantitative Methods in Clinical & Public Health Research.)

My TA asked the edX staff and a response rolled in many weeks later as the question got kicked around until it found someone who knew the methodology.  I know that you are on the edge of your seat, waiting for the methodology.  Here goes.

Each of the 500 admitted and enrolled students checked off one or more of the five available time slots.  The computer assigned 100 to each time slot, based on our availability.  The 20 TAs were assigned, four to a time slot, in a similar fashion.  Then we were randomly assigned, within each time slot, to one of four groups.

There were two "exposures" and four possible combinations.  One half read US case law only (controls) while the other read fewer US case law but more international law.  One half used the edX discussion boards only (controls) while the other half also used Nota Bene PDF annotation software to collaboratively mark up the weekly readings.  I was assigned to the "double exposure" group, which studied international copyright law and used Nota Bene.  (If you haven't tried Nota Bene, give it a whirl.  I really like it.)

Come to think of it, there is a third exposure--online or bricks and mortar.  In one section, the TA let it slip that we came to consensus on the relevant section of law and precedents faster than the HLS section.  That's when I realized that they could compare us to not just other CopyrightX students, but also possibly to the HLS students.

In early June, we will be notified of our final exam results.  Undoubtedly, the performance data between groups will provide researchers with rich material.  I hope that our participation as guinea pigs will make online education better for all.

I learned as much from my fellow students as from the TA. The accreditation doesn't matter to someone in my situation (though the librarians and archivists were taking the class as part of their jobs).  Being in a very serious cohort with breadth and depth of real world experience and with true interactivity were valuable to me.   I would pay money for such courses once they move out of clinical trial--if the RCTs prove MOC efficacy.  ;-)

That said, I initially put a blanket copyright notice at the bottom of this blog because I didn't want to give away any rights before I understood them.  Now that I am more aware, I think I will change the copyright to Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported as a baseline and then put separate notices for content that I want to protect differently.

I'll also post later about what the licenses mean and how I will apply them to my blogging, sewing, knitting, software and data activities.  Stay tuned.  Watch this footer.  ;-)

Leave a comment if you think this is interesting or I should just stick to the sewing and knitting stuff.

Addendum:

Maybe not so easy

I was surprised by the responses to some problems are easy to solve.

First, I want to thank all those who commented and emailed because they really did help me to rethink the problem.

My first visceral response was that, if the rationale for disenfranchising women from the democratic process is that *men* cannot control themselves around women, then the creatures with no self control should be the ones that are disenfranchised.  After all, who wants to be ruled by an out of control democratic mob?

The responses, save one by email, gave practical suggestions for how to segregate the genders and still allow women to vote.

But, I want to ask how people would feel if we substituted race for gender?

What do you think about George Wallace's infamous speech that included the line, "segregation now, segregation tomorrow and segregation forever,"? You can hear an NPR story with the quote here.

Why must women cover themselves from head to toe, stay imprisoned in their homes, be denied education and autonomy, etc just because *men* say that they are unable to control themselves around women?

Does segregation eliminate the problem or perpetuate the "otherness" of women?

We now (mostly) accept in the US that racial segregation was bad and that racial integration in all aspects of life, public and private, is a social good.  We used the might of our government to impose this social good upon communities who did not accept this.

President Eisenhower sent the U.S. Army’s 101st Airborne Division to protect the Little Rock Nine as they tried to attend a historically white high school.  The other two branches of government, the US Supreme Court and Congress, also used their might to force integration upon unwilling southern states.

At the time, southern states used the same defense--that racial integration is just their culture and that nothing could be done about it.

Fifty years later, racial integration did not cause the sky to fall and most people, especially young people, see it as the natural order of things.

So why do we accept analogous arguments today for the segregation of men and women?

I really want to know why gender segregation is different than racial integration and why we should accommodate those who insist upon it.

ThemeFriday Sewing Space

This Friday, Me Made May '13 takes us on a tour of sewing spaces. Here's the northeast view of my 12x13 foot sewing room. Patterns are usually covered by the fabric curtain. Zero waste bin for scraps are below the patterns. UFOs are in bin on table to right.

Books are in IKEA kitchen cabinets above table. One primary sewing machine and serger. Backups of both machines for when sewing with others or in contrasting thread colors.

Southeast view with pressing station and UFO bin of half-finished projects.

Messy studio.  The closet and bins under the tables are full of fabrics, yarns and clothing awaiting refashioning.
KC asked for a closer look at Vogue 1310.  Behold, the pieced front.

I made the top from the leftovers from the matching bias skirt.  The linen started out a light celadon green while the cotton jersey was a pale olive.  I over-dyed the linen to match the jersey.
I cut the front in a size 12 and the back in a size 10.  When mixing a knit and a woven, I generally cut the woven a size larger than the knit.  Notice that the top has been washed more often than the skirt and is more faded.  They started out the same color.
I improvised a bias skirt pattern with a knit yoke.  Rather than make a straight tube, I joined two pieces with angled seams to simulate two darts for a smoother fit.

I found the linen and jersey at Trash for Teaching.  They hold open family studio workshops every Sunday afternoon in their Gardena warehouse.  You can also purchase their recycled materials for $1-2 per pound.  They asked Pennamite and I to lead workshops.  Pennamite already led one about how to crochet fabric strips (donated by American Apparel) into bags and home dec.  When I am less busy, I will lead one showing how to make scarves from fabric scraps.

I purchased the rayon skirt lining and cotton voile top lining from SAS Fabrics.  I bought new thread, elastic and a pattern, so the outfit is not 100% recycled content.  However, I used nearly all the scraps of each piece.

I've already shown Iris' jersey shorts.  The leftovers became my skirt yoke and top back.  Her race shirt from the West End 3k was remade into a fitted raglan shirt along with some slinky knit from the Michael Levine Loft.  The black fabric on the cardigan back and the dark olive jersey for the skirt came from SAS.  The Loft and SAS are odd-jobbers and these small scraps were leftovers from the garment industry.
 My top, skirt and Iris' shorts, showing the dyed-to-match set.

Yeah, our family dresses in trash. Or, you can flip it around and say that we dress sustainably. You decide.
