2016 in books

2016 has been a rough year for me.  I really didn't know how to respond.  But, I recently read a book that helped me make sense of what I was observing.

So, I'm gathering my friends and family around me by throwing a party tonight for LA-area friends.  I need to get back to picking up clutter and cooking.

I'll quickly share my eclectic 2016 reading list on Goodreads.  I read to learn; I read to connect to other humans; I read for entertainment; I listen to audiobooks to help me fall asleep.
My thoughts about the book, What is Populism, by Jan-Werner Mueller:
This is a short book and should have been readable in one evening had the last election not freaked me out so much.

I had to put it down when too discomfited by PTSD from all the rhetoric that reminded me of living under Chang Kai Shek and martial law.

Even my 6 yo self could recognize the lies in our textbooks. I never expected to live in a post-truth United States.

Chapter 1 describes 'What is populism.' This is the scariest part for me, which brought up PTSD.

Chapter 2 explains 'How populists rule.' This scares me.

Chapter 3 gives some proscriptions for how to fight populists, from a scholar who has studied how populism waxes and wanes in regimes around the world. It gives me hope b/c some countries have defeated populists. But it is difficult as they change rules as soon as they are in charge to make it difficult. E.g. North Carolina voting changes and the Supreme Court that ruled that Lily Ledbetter couldn't file for discrimination because she didn't do so within 6 months of the wrong-doing, even while ruling her employers can withhold information and stall requests for info as long as they like. This is populism.

It's a difficult book, because of the emotional stuff. The language may be difficult for people who aren't used to academic treatises. But this book is essential reading for our times.
Bad Dad's thoughts on the same book:
With the election of Donald Trump as the 45th President of the United States of America, What is Populism? is officially promoted from useful reading to essential reading. Jan-Werner Muller first defines populism both in terms of what it is and isn't - the defining feature of populism being a claim to represent a "real" citizenry that excludes elites and/or minorities. Another important feature is a derisive attitude towards the give and take of the political process and a rejection of the entire idea of political pluralism.

Then comes the scary part of this monograph, where Muller describes how populists rule. Populists start by controlling and purging the government bureaucracy (note the Trump transition team's requests for names of DOE climate scientists and State Department personnel working on women's rights issues). After decrying the corruption of the previous regime, populists are incredibly tolerant of their own corruption and don't seem to care when this corruption is pointed out (sound familiar?). Finally, populists change the rules of government so that their party is difficult to remove and their policies are difficult to change (are events in North Carolina a sign of what is to come in Washington?).

The third chapter is about how to talk to populists, and explains how those who want to protect political liberalism need to address the very real concerns that are causing populist movements to flourish. Many, including me, will feel that they are reading this chapter a bit late in the game.

Muller's monograph is very well researched, and has numerous examples from populist movements of both left and right (including countries such as Venezuela, Bolivia, Hungary, Poland, Russia and Turkey). Although its tone is very academic, the intelligent layperson should have no problem with this book - unless it totally freaks him or her out.
If you view his list of 2016 books read, you can see why I love him so and hate his housekeeping.

Colorado Gives 2016 Update

I already explained my misgivings about Colorado Gives and the inefficiency of philanthropy.

I found the Colorado Department of Revenue's Annual Report for 2015.

The dismal results of Colorado Gives 2015 proves my hunch is correct. A very, very small number of people (less than 63,690 Coloradans) gave a measly $28.5 Million (much of that in recurring gifts that would have occurred anyway.) estimates that Colorado has 4.2 million adults 18 and over.  This means about 1.5% of Coloradan adults gave something.

Colorado taxes are a regressive disgrace.  They manage to be even more regressive than the sad nationwide average.  See how your state stacks up.

 To file part-year taxes for Colorado and California, I first calculate my taxes as if I solely resided in CA or CO.  I would pay about 3% more of my gross income to live in CA over CO. But Californians enjoy more legal, environmental and economic protections as well as higher levels of service from government.  If Colorado just followed California's example, we wouldn't have to resort to begging.

During the presidential campaign, one candidate bragged that not paying taxes makes him smart, normalizes tax avoidance.  Furthermore, he also gave virtually nothing to charities.  This normalizes selfishness.  He didn't just normalize it, he celebrated selfishness.

Giving to charity is for chumps under the current system.  Charities (thousand points of light) fills holes in the societal needs dike while states enable wholesale avoidance of responsibility to society with regressive tax codes and low tax rates.

I'm sitting out Colorado Gives.  It's a band-aid as long as Colorado has TABOR (the so-called tax payor bill of rights.)

If you feel like giving, please donate to High Country News.  I like to buy an e-subscription and donate a hard copy to a classroom.

Big Data, Big Planet

I wrote Big Data, Big Planet for UCARConnect explaining what I do to K-12 teachers and high school students.

Climate reconstruction with atmospheric rivers, including the one that flooded one third of Los Angeles in 1938.

The November 2016 issue of UCARConnect is all about Data: The Currency of Science.

The unique pain of living in a swing district

If Leo Tolstoy lived in the South Bay, I wonder what he would make of this election?

We've received most of these flyers.
Due to gerrymandering, very few races are really in play. The California 66th Assembly seat in south coastal Los Angeles county is an exception.  This may be the most important Assembly race in California.

Al Muratsuchi (D) won in 2012, helping CA Democrats win the 2/3 super-majority in Sacramento necessary to pass laws in the aftermath of Proposition 13. David Hadley (R) narrowly won in 2014, which ended the super-majority and brought back gridlock. Now they are battling it out in a rematch.

The burden of living in a swing state pretty much sums up our experience living in a swing district within blue California.

We are being stalked at home by phone calls.  We get postcards from Independent Expenditure (IE) groups accusing Hadley for being a Trump surrogate (which he denies) and Al Muratsuchi of protecting pedophile teachers and of voting to repeal Proposition 13 for residential properties (both lies.)

At first, I wondered why we were receiving so many postcards from the Hadley camp (both from the official campaign and also by IEs funded by out of state right-wing billionaires.)  This election season has been a crash course in election tactics.

The postcards with bold fabrications against a Democratic candidate, sent to a home with registered Democrats, is all about suppressing Democratic votes.  If they can sow enough confusion, they hope to dishearten us enough to not bother to vote.

It worked in 2014, when Hadley won by 700 votes by using the exact same lies and tactics.
In 2014, only 40 percent of the 66th Assembly District’s registered voters showed up to the polls, versus 70 percent in 2012. That led to a loss of about 78,000 total votes.
I think that the total disregard for truth--lying about your opponent early and often--is Trump-like. So I do understand the logic of comparing Hadley to Trump.  The two candidates are not equally bad.

#nastywomen and #badhombres, get out and vote!

Your Colorado Voter Guides

Hey, that's me, a volunteer!
This week, I've been walking around my precinct distributing the BoCoDems 2016 Voter Guide.
This Voter Guide was dropped off at your door, or mailed to you by a neighborhood volunteer!"
It's a long ballot, with many Ballot Issues.   By press time, the BoCoDems had made recommendations on all but 4 of the initiatives.

Once again, my Colorado friend has written a well-considered guide to the issues.  To learn more, go to Colorado and Boulder Ballot Issues.

The two guides differ on Boulder County Issues 1B & 1C and BVSD Issue 3A.  So please read them and make up your own mind.

As long as I have your attention, vote the down-ticket races.  If you don't vote, then someone else decides for you.  Moreover, you won't get national candidates that you are happy with unless you give them experience at the local level.  Get civically-engaged.  Convince your friends and family to become civically-engaged.

We have a presidential candidate for a major party that says very dangerous things about minorities, women, the disabled and climate scientists.  This election hits very close to home.  If nothing else, please vote to protect me.

A tale of 2 t-shirts

I made two woven t-shirts this summer.

I used an old pattern for knits (8998 left) and a new one for wovens (6610 right).  I bought the black/gray ikat in NYC while shopping with Claudine.   I found the blue batik in the remnant basket at Fancy Tiger*.

Both envelopes describe the tops as semi-fitted.  I had previously used Burda 8998 with wovens before, and remembered to size up from 14 to 16 (going from knit to woven).  Since Burda 6610 is designed for wovens, I made it in size 14.  If I lay 6610 on top of 8998, you can see that the black one is slightly roomier.

 6610 has bust darts, for a better fit.

It also has back shoulder darts!

I shaped the hem on the black t-shirt for a slight elliptical high-low effect.  To help the hem lay flat, I hemmed it with a bias strip instead of a turned hem.  I'm wearing it with Simplicity 1887 shorts Version 2 in the photo below.

The front shoulder slope for 8998 does not match the slope of the back piece.  If you don't trim it to fit the back, the shoulder seam slants toward the back in an odd way.  The rest of the pattern is drafted accurately.

Burda 6610 is drafted really well, and I appreciate the way the darts elevate the fit and look.

It's a bit tighter around the upper chest than I like.  Next time, I will either size up to a 16 or use a stretch woven if I sew a size 14.  YMMV.  Fit is subjective and I prefer roomy over tight.

I think this top will go to my DD, who says she would like some more color in her wardrobe.

* Last Saturday, I took a fabric shop tour of Denver, visiting Fancy Tiger, Fabric Bliss and Colorado Fabrics while working my way south to IKEA.  I chanced upon Fabric Bliss while going to an exhibition at Metro State Univ Center for Visual Arts.  The Broadway and Santa Fe corridors are chock-full of galleries and interesting shops for makers.  If you are visiting Denver, I highly recommend spending a half day or more in this area.

Colorado Fabrics is the largest fabric store in our time zone and, when they move in January, they will be huge.  Right now, they don't have enough room to stock everything they would like; the selection of apparel fabrics is hit or miss.  Last June, I didn't find anything to tempt me other than the hard-to-find notions on my shopping list.

They offer a good selection of designer overstock fabrics in the front, mostly from LA and NY, at NYC garment district prices.  They also have a big and well-organized bargain section in the back with lower quality (but still good!) fabrics at LA-area (lower than NYC) prices.  Last weekend, I wanted to take home all the fabrics from the front section.

These digitally-printed rayon challises have a delightful hand.  Three of them came home with me.

If we want brick and mortar fabric stores to stay in business, we have to support them.  I'm happy to do my part.  And the fabrics I brought home are drool-worthy.  I'm sure you'll see more of them later.

#sewphotohop Day 27: other interests

It's day 27 and I'm running out of steam for #sewphotohop.

One look at the word cloud in the column at right shows that I have a lot of interests.

When I started this blog, I had to be coy about my day job because I worked in a military lab, and the security officers really, really did not want their scientists to be out in public. It's not that I was doing anything to be ashamed of. In fact, I really enjoyed the work I did there. It's just not in the culture there to bring attention to oneself.

Since 2014, I've been providing data support for climate and weather research.  We are an open access data provider, funded by the National Science Foundation.  Both the data and the data tools are provided free thanks to governments around the world.  If you pay taxes (and I hope you do), then you help pay for this data infrastructure.

All this is an excuse to provide a list of data links.
I have a passion for making stuff.  I have a passion for data.  I have a passion for sharing my knowledge and skills.

*National Software Reference Library, a division of the National Institute of Standards and Technology (NIST).  I received my PhD at JILA, another part of NIST.

Pockets on my mind

I'm a big fan of pockets in my own clothing.  There was a time when I skipped them, or only inserted them in the side seams (totally unflattering and uncomfortable for my build), in the rush to be done with a sewing project.

Now, I sew to get exactly what I like.  If it takes longer to make it, then so be it.

Imagine my delight when I saw this slideshow of Marni's S/S 2017 collection:

Photo from NowFashion via NYT
An entire fashion collection devoted to exploring pockets!

BTW, I read the NPR fact-check transcript, but could not bear to watch the debate last night.

Did you read the Politics of Pockets?  There's all sorts of good historical stuff about suffragettes, rational dress, the "New Woman", and Hillary Clinton's pantsuits.

Read this story about Susanna, a custom clothier in Beverly Hills who makes some of HRC's pantsuits.  Fox and right-wing pundits tried to deflect criticism that Trump-branded clothing is all made abroad in low wage countries by suggesting that HRC's pantsuits are made in Bangladesh.  They lie.
Susanna Forest, of Susanna Beverly Hills, has been handcrafting women's suits in the United States since 1976. From design to manufacturing, every step of her process is carried out entirely from her atelier in Beverly Hills, California. Susanna Beverly Hills garments are the product of hundreds of hours of American labor, and women, including Hillary Clinton, can be proud to wear a garment that has been crafted with the absolute most care and skill here in the United States.
I have a small quibble.  The article says that this white suit she wore at the convention does not have pockets.  Click to embiggen the photo.  Do you see a faint outline of welt pockets on her jacket just below the waist?  Methinks her jacket has a pair of pockets, but they are so skillfully done, they are practically invisible.

Enlarge this to see the hip jacket welt pockets.
I'd like to make the jacket below for my S/S 2017 collection.

V8732 is sadly OOP.
But first, I need to make progress on F/W clothes from DD and myself.  I promised her 2-3 colorful tops.  I need to make a few for myself and clear a backlog of 3-4 sweaters patiently awaiting seaming and finishing touches.

Pushing back against Weapons of Math Destruction

I'm such a huge Cathy O'Neil fan, that I put Doing Data Science: Straight Talk from the Frontline on my very short list of recommended books for scientists and data scientists. I wrote:
The most hands-on of the meta books or the most meta of the hands-on books? Not many introductory books include a chapter on ethics but more should.
Weapons of Math Destruction is the book about data science ethics that I've been waiting for.

Listen to the interview with author Cathy O'Neil on All Things Considered.

I especially like this exchange:
MCEVERS: So it sounds like when you're saying, you know, we have these algorithms, but we don't know exactly what they are under the hood, there's this sense that they're inherently unbiased. But what you're saying is that there's all kinds of room for biases.

O'NEIL: Yeah, for example, like, if you imagine, you know, an engineering firm that decided to build a new hiring process for engineers and they say, OK, it's based on historical data that we have on what engineers we've hired in the past and how they've done and whether they've been successful, then you might imagine that the algorithm would exclude women, for example. And the algorithm might do the right thing by excluding women if it's only told just to do what we have done historically. The problem is that when people trust things blindly and when they just apply them blindly, they don't think about cause and effect.

They don't say, oh, I wonder why this algorithm is excluding women, which would go back to the question of, I wonder why women haven't been successful at our firm before? So in some sense, it's really not the algorithm's fault at all. It's, in a large way, the way we apply algorithms and the way we trust them that is the problem.
I hope you read or listen to the interview. Perhaps we can do a virtual book club and read it together?

In case you were not a reader of this blog in 2008, I wrote about my experiences using a proto credit-scoring algorithm while in high school student working part-time for Citicorp in the mid-1980s.  I did (with my boss' support) what I could to push back against arbitrary scoring algorithms when I felt they did not accurately capture an applicant's credit-worthiness.  It's also a time capsule for a time when we could assume that health insurance companies would eventually pay so that healthcare liabilities did not count against employed people.

What I didn't write in 2008 and should have, was that I applied to both Kelly and Kelly Technical Services. Kelly sent me to do the lower-skilled clerical work for slightly above minimum wage. Kelly Technical Services sent a male former classmate (who needed my help to debug one of his homework assignments) to work on implementing the software algorithm that eventually replaced the clerks like me. He got paid more. A lot more.

Bias was not created by algorithms.  We built the algorithms in our own image.

Low-carbon laundry

When I posted the picture below on Instagram, several people asked for more info about this Nina Soft centrifuge/extractor.
Yesterday, the Nina Soft spun over a liter of water+residue out of three loads of laundry.
My condo doesn't have an in-unit washer or dryer.  I have to walk all the way to the other side of the building to use the washer ($1) or the dryer ($0.75 for 50 min).  Moreover, the washer doesn't have a second rinse option, which I need because my skin is so sensitive to detergent.

When sharing a washer with others, I have no control over what kind of products they use.  They might put in perfumed detergents or fabric softeners.  That leaves residue in the washers and dryers.

In Los Angeles, I use a clothesline.  I hang most of my laundry on the line, but put small items like socks and sturdier underwear in the tumble dryer along with shirts.  By the time I am done hanging up the clothes on the line, I can hang up the slightly damp shirts to finish air-drying.  The undies and socks take just a few more minutes to complete.  I probably run the dryer for about 15-20 minutes per load of wash.

At the condo, the dryer won't start until you put at least $0.75 cents.  It doesn't matter if I want to run it for 1 minute or 50 minutes, it costs $0.75.  Each additional quarter provides an additional 20 minutes.  The clock runs even when the dryer isn't.  That means you pay for time when the machine is idle and the next person can't use your unused time.  The contractor that has the monopoly on our building is not interested in changing his pricing scheme.

My home laundry equipment.
Over the last year, I developed a system that works for me.

The Nina Soft is a home version of the extractor that you find in laundromats.  It's essentially a big centrifuge for your clothes.  The Nina Soft spins out water, detergent, chemicals and hard mineral deposits that would otherwise bake into your clothes.  It also reduces dryer time by ~50%.

I originally bought it for tie-dyeing.  Spin the excess dye out before rinsing, and you save tons of time and water.

I hand wash small amounts of laundry in the green baskets in my bathtub with the Breathing Washer.  It's a plunger-like thing used by campers, dyers and felters.  Unlike plungers, the Breathing Washer doesn't splash.  It does make a wheezing sound that gives it it's name.  It's a good 10-minute upper body workout.

When I wash things in my tub, I can rinse twice.  Then I spin it in the Nina Soft and air-dry it.  This also helps humidify my condo in arid Colorado.

When I have a lot of laundry, I use the shared machines in parallel.  At 7 AM, the earliest we are allowed to start laundry, I can usually find three open washers on consecutive floors.  (Dark, Light and Medium colors.)

When I take the laundry out of the washer, I spin all of it in the Nina Soft.  Then I either tumble dry them or hang them up.  I found this large maple folding drying rack at McGuckin Hardware.  It's made in the US and much sturdier than any other racks I've seen at any price (including the one from LL Bean).  It's not expensive, either.

In this way, I limit my exposure to detergents and reduce dryer use to about an hour for all 3 loads of laundry.

I got my Nina Soft from Dharma Trading, my preferred supplier of all dyeing/fiber art goodies.  I have no affiliation with them other than ordering from them for 20+ years and wanting to make sure they remain in business.

I bought the Breathing Washer and a plastic washboard from Japan from Amazon.  They also sell the Nina Soft.

The green baskets and laundry octopus come from IKEA.

The case against antibacterial soap

Yesterday's big environmental news was the FDA ban on triclosan, triclocarban and 17 other toxic chemicals commonly added to soaps.  Scientists' reactions ranged between "Huzzah!" to "Why did it take 40 years for the FDA to listen to us?"

Bad Dad and I both earned BSs in chemistry so we are familiar with the issue.  However, I realize that most families don't have even one BS in chemistry, especially because chemistry is one of the least popular majors in the United States.  (Which is a shame, because chemistry is truly the "central science" that bridges the life and physical sciences, and gives people a great foundation for understanding the world.)

Here's some stuff to think about and discuss around your dinner table.  OK, we are comfortable discussing bioreactors and biosolids around the dinner table, but maybe you want to wait until after everyone has finished eating in your home.  ;-)

Any soap or body wash that says "antibacterial" probably contains one of the newly-banned substances.

For these to work effectively, you have to wash with them much, much longer than most people do.  You know how long surgeons and surgical nurses scrub their hands (until they are red and raw?); that's how long.  That means, outside of hospitals, antibacterial soaps are not doing anything but going down the drain.

What happens to stuff that goes down the drain?  Glad you asked!  I wrote a series of posts about that.

Think about all the stuff you send down the drain (kitchens, bathrooms, laundry).  Think about everything you ingest and then excrete.  BTW, waste water is a great way to find out how much and what type of drugs/pharmaceuticals people are ingesting.

Your sewage is sent through a screen to separate solids from liquid. The solids are often sent through a bioreactor with bacteria that breaks down the solids. The biosolids (with or without the bioreactor step) are spread on agricultural fields as fertilizer, landfilled or incinerated.

This can be a good thing. Incineration reduces waste AND produces energy. Biosolids are cheaper for farmers (about 1/4 the cost of petrochemical fertilizers) and reduce our reliance on fossil fuels.

The problem is us. We send too much non-necessary chemicals down the drain.

ASU Professor Rolf Halden gave a plenary talk last month at the American Chemical Society's meeting in which he showed that just two chemicals, triclosan and triclocarban, make up 60% of the pharmaceuticals found in municipal biosolids.

This chart is a screen shot from his article in Nature. Note that the horizontal axis is logarithmic so a difference of one tick mark is a factor of ten.  Click to make the graph bigger.

The US produces (and we presume, use) about 2,000 metric tonnes each of triclocarban and triclosan.  4.8-48.2% of the triclocarban ends up in biosolids.  The rest probably remains in the water.  1.8-18% of triclosan ends up in biosolids; more of it remains in the water than triclocarban.

Excerpt from Pharmaceuticals and Personal Care Products in Archived U.S. Biosolids from the 2001 EPA National Sewage Sludge Survey:
Of the more than 7 million tons of sewage sludge produced in the United States in 2004, about 50% was applied to land as fertilizer or soil amendment, and 45% was disposed of in landfills or as landfill cover.
 I've already written about how triclosan can photo-degrade into dioxin under UV light. ("Dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer.") It doesn't matter whether the triclosan is applied through biosolids or irrigation water. This finding has now been replicated in labs around the world and is accepted scientific fact.

But, incinerating triclosan is also extremely risky.  Excerpt from Halden's research home page:
In addition to toxins in wastewater, Halden’s team is researching the emission of toxic dioxin into U.S. air from incineration of triclosan-laden municipal sludge, or biosolids
Furthermore, these newly-banned substances have all been found to bio-accumulate, not just in earth worms and frogs but in you and me.  These are hazardous chemicals that should not be in our ecosystem.

Antibacterial soaps have their uses--in hospitals--but should not be in widespread use in homes.  They do nothing beneficial under normal home use, but cumulatively do great environmental and health harm.

September is both National Preparedness Month and National Sewing Month.

I'm spending September updating the NCAR Upper Air Database, which can be used to help assess weather hazard risks, and sewing my daughter's back-to-school wardrobe.
There is a Fall wardrobe in here.
#natlprep is giving me the kick in the pants I need to discuss with my family our disaster plans.

What are you doing in September?

The perennial dilemma

Air is a common resource. Each of us suffers from degradation of the air quality, but we have no little control over what others do to the air that we personally breathe.

When people think of the Boulder, they don't often think of air pollution. But, the elevation and topography (mountains to the west and northwest and the Louisville Rise to the east and southeast), and the automobile traffic in this small town, mean that the nose-level pollution in central Boulder is usually higher than the western coastal neighborhoods of Los Angeles. (My doctors had recommended in the 1990s that I move away from Boulder for my health and suggested coastal LA as a good alternative.)

You can't see ozone, but it is created by a combination of automobile exhaust and sunlight, specifically UV radiation.  At high altitudes, we have plenty of UV (and cosmic ray) radiation.

Ozone is a lung irritant.

We can't control sunshine, so the only way to keep the ozone from reaching dangerously high levels is to refrain from driving.  That means you AND me.

But, sensitive people are cautioned from strenuous outdoor exercise during high ozone days.

What does an asthmatic do when an Ozone Action Day is called?  Ride my bike and possibly have an asthma attack?  Drive solo and pollute the air even more?

The combination of pollen and ozone is particularly irritating.  People with pollen allergies can be affected by lower levels of pollen when ozone is present.  The only time I ever ended up in a clinic gasping for breath was when I went for an after work run (in grad school in the 1990s) up Boulder canyon during a day with both high ragweed pollen and high ozone.  I now get allergy shots and that has helped somewhat.  But, I still avoid outdoor exercise when pollens are especially high.

Fortunately, my bike and I can pick up a shuttle bus to work 2 blocks from my condo and be whisked up to the main entrance of Mesa Lab.

So many of my coworkers did the same, we filled up both the front and rear bike racks of the van.

Some even took the RTD bus to meet the shuttle.

The best part of leaving the driving to someone else is that my hands are free to take pictures like this.
The ride home is an 800 foot elevation drop, so it is not the strenuous type of exercise that would be dangerous for me.

Wildfire PSA

With wildfires burning all over the western United States and floods ravaging Lousiana, this is a good time to reread Fire is a river that runs uphill.
One major reason that fire fighting in the western forests has become more expensive is the number of structures (homes) being built in the trees. One Colorado newspaper had the guts to run a story questioning if our firefighters should risk (or lose) their lives protecting the vacation homes of the rich after twelve firefighters died in the Storm King Mountain fire.

Sewing in Series: Simplicity 2263

Why reinvent the wheel if something works?

I know that 'indie' and 'designer' patterns are all the rage in the blogosphere, but the 'Big 4' (but now really 6?) put out some solid patterns without much fanfare (e.g. blog tours.) Take Simplicity 2263, which looks rather pedestrian.

Prosaic pattern envelope.  The ASG symbol is a clue.
All patterns are 'designed' by someone.  Bold face names do not have a monopoly on good design.  I've had more misses than hits with indie patterns and their instructions.

However, I pick up some signals that others may overlook.  Have you heard of American Sewing Guild (ASG)?  ASG probably doesn't have a booth at 'Maker' faires, but ASG members know quality sewing.  (Disclaimer, I used to belong, but am not currently a member.)

Patterns with the ASG seal of approval tend to be very well drafted and extensively tested.  When I see a new pattern with the ASG seal, I pay attention.  This blouse with a back that extends over the shoulder to the front is a winner.  I've sewn it three times.

Three versions of Simplicity 2263
I made the first version in 2013 with a 1/2 yard remnant of rayon challis that I purchased at Britex at PR Weekend SF 2012.  1/2 yard is obviously not sufficient, so I improvised a yoke with a scrap of ponte.

Not faithful to the pattern, with a yoke and knit neckband.
When I saw this gray and red rayon challis at Elfriede's in Boulder, I snapped up a yard to sew another one for an upcoming MIT alumni event. (Is it the female version of a school tie?)

I used the serger for version 1.  Version 2 and 3 got the full french seam and bias binding clean finish.

I love a neat inside.  
I recently made a third version, with a rayon crepe I bought at SAS Fabrics in Hawthorne (near LA.)  Rayon crepe is rarely found in fabric stores.  When I found this small piece in a pretty print, for only $3, I brought it home without any immediate plans for it.  After I made version 2, I knew this remnant wanted to be version 3.

Version 3 with bonus view of kitchen.
Shoulder pleats instead of gathering.
You want to see them out in the wild?

Version 1 at the Getty Center in Brentwood.
Version 2 at the Petersen Museum in LA.
Version 3 outside my office.
A great, easy-to-make and easy-to-wear basic.  What's not to like?

More statistical nonsense

I'm bereft that Serena lost today.

There's also the matter of a presidential candidate suggesting or joking that people assassinate his opponent and the judiciary.

Let's talk about something that makes me mad, but only mildly so.  This also gives me a chance to jump up and down on my soapbox about bad data crunching.

Exhibit A, this piece of click bait from the NY Times with a tone of schadenfreude toward engineering majors:
I clicked and read these counter-intuitive numbers.
This doesn't jibe with my personal experience. Physical scientists that I know are very, very civically engaged. How could we be such slackers when it comes to getting to the voting booth when I see "I voted" stickers on everyone in lab on election day?

Do I know a very atypical set of physical scientists?  I had a hunch that, perhaps, it is because (outside of school and student jobs) I have always worked in national labs that require US citizenship?

I did a little research.

First, I went to The National Study of Learning, Voting, and Engagement (NSLVE) website and read about the project. There appears to be a database accessible from that website. Because I'm not a participant in the research, I lack access to it.

There also appear to be some scholarly articles, which might have the summary data cited by the NY Times.  Again, I lack access to the articles.  (I'm not going to pay $41 for 24 hours of access to an article that may or may not have the data I seek.)

Search for "The National Study of Learning, Voting, and Engagement report". I was able to find several, including reports for Columbia and Long Beach Community College students.

In each report, I saw that the figures for % of eligible students voting by major was calculated using IPEDS and the same percentage was applied to all majors at a school, given the schools' overall demographics.
This is based on the percentage of non-resident aliens reported by your institution to the Integrated Postsecondary Education Data System (IPEDS), and is more reliable than the demographic data campuses provide to the Clearinghouse at this time.
Do you see the statistical flaw? The reports gave the numbers with this caveat at the top:
Your students broken down by field of study. Please note that we are not able to adjust these voting rates by removing non-resident aliens.
The NY Times' poorly-researched and reported listicle did not include any methodology or context.

OK, now let's read what the National Science Foundation has to say about Higher Ed in Science and Engineering.
  • About 60% of all foreign graduate students in the United States in 2010 were enrolled in S&E fields, compared with 32% at the undergraduate level.
  • Foreign students earned 57% of all engineering doctorates, 54% of all computer science degrees, and 51% of physics doctoral degrees. Their overall share of S&E degrees was one-third.
  • In 2009, temporary visa students earned 27% of S&E master's degrees, receiving 46% of those in computer sciences, 43% of those in engineering, and 36% of those in physics.
Moreover, physical science and math students are vastly outnumbered by business and other students; the US graduated 19 business majors for every math or statistics major in 2011.

Let's list what we know:
  • Statistics tying individual students majors and voting behavior are difficult to obtain for privacy reasons.
  • They had to make estimates based upon school-wide statistics.
  • Each school reported the % of their students that were not on temporary visas.
  • NSLVE then applied the same % to all majors, even though they know this is inaccurate. They reported that this is a source of error.
  • They also removed students that were younger than 18 and not eligible to vote.
  • The % of students studying STEM is quite low compared to other majors, particularly business.   That gives larger error bars to STEM voting numbers, even without the eligibility estimation.
  • STEM students as a whole make up ~20% of the total undergraduate (UG) population, but 30% of the foreign UG student population; their voting participation is underestimated by the NSLVE methodology.
  • This means non-STEM students are more likely to be US natives; their voting participation is overestimated by the NSLVE methodology.
  • Foreign-born permanent residents are a wild card.  They do not need a temporary visa.  Yet, they cannot vote.  They are also disproportionately likely to be studying STEM.
  • Foreign students make up a disproportionate share of STEM students at every level, but particularly so at the graduate level.  They dominate in many STEM fields.  Thus, their voting participation is VASTLY underestimated by the NSLVE methodology.  (That 40% of physical science students could very well be 90% of eligible students.)
I found all sorts of interesting information, especially at the National Center for Education Statistics:
Anyway, after examining the data, I think it is very, very likely that physical science students that are eligible to vote do so at higher rates than journalism students.  I'm sure The average physical science student is better with data than the average journalism student.  We might even be better than the average NY Times journalist.

Another piece of bullshit debunked.

Harley Quinn sadness

Remember the Harley Quinn costume I made for my daughter?

And my ambivalence about the hyper-sexualization of females in comics?

Check out the slide show about Harley Quinn cosplay in the LA Times. Look at the difference in (un)dress between the male and female cosplayers.

Then check out this tweet from David Helder pointing out the sexism at #defcon, a computer security conference. Please note, this is happening in 2016.
Hacker Jeopardy. Category is "Dicks". Men play. Women give them beers. Why aren't there more women in security?

Scroll down to read the discussion.  This is the state of one corner of tech.  I am not sure other areas of tech are any better.

Two links while I catch up at home

I'm back home after two weeks away.  I'll post more about the trip when I come up for air.

I found a couple of related links too good not to share.

In What is fashion good for? Part 1, Timo Rissanen explains that the current fashion system is terrible for the planet because it is terribly wasteful. It's also very harmful to the people involved in creating the cheap clothes that most people wear.

Home sewing is part of the solution.

The NYT profiled the McCall Pattern Company in Sewing for the Instagram Generation.

Cultural Tourism

My two talks last week came and went.   People came up to talk to me all week about some of the points I brought up, so I guess not everyone snoozed.

DD is at sleepaway camp.  DH is at a meeting in Boston this week.  We decided to spend some vacation time together on the east coast before heading back west.

I've been enviously reading other sewists' blogs about their visits to
I really, really wanted to explore the permanent collection at the Philadelphia Museum of Art and to see the Barnes Foundation's collection again. Philly is bursting at the seams hosting DNC this week. But, this is the week I am on the east coast.

Here's my schedule for the rest of the week in case you want to join me for cultural bingeing, shopping or eating:
M: Boston
T: AM Amtrak to Philly. PM museums
W: Museums, strolling Philly
Th: AM Amtrak to NYC (Chelsea), PM strolling, shopping Manhattan
F: Museums, shopping, strolling
Sa: Brooklyn (any recommendations?)
Su: Museums, bookstores, strolling
M: AM strolling, PM fly home

I'm interested in seeing these other exhibits if time permits

And I'm all about the food.

If this sounds interesting to you, leave a comment with your contact info and day(s) available. Thanks.

Over the years, I've made at least six nightgown renditions of Simplicity 4767.  DD was so fond of this pattern, I graded it up from size 8 to 14.
After her recent growth spurt, I decided to find an adult-sized pattern.  You'd think it would be easy to find a peasant top or night gown pattern but I didn't find any in the pattern books.

I probably could have traced one from a BWOF magazine in my collection, but then I spied newly-issued Simplicity 8124, a Cynthia Rowley pattern.

The dress looks scandalously short and full. One breeze or sneeze and...

The pattern envelope says that the bust on the XS is 57.5"!  Fortunately, the romper had a more moderate 42" circumference.
I adjusted the sleeves to full length for the winter-weight flannel gown shown above and below.  I also lengthened the body to 48", flaring it out at the bottom to the full width of the fabric (about 40" wide after shrinkage.)

That was actually the third nightgown I made last week.  Imagine #2 in this fox fabric.

I forgot to take a picture of the completed first gown.  But, I have two progress shots, which I previously posted on IG.

I used French seams on the cotton shirting one and used my serger to finish the seams on the two flannel versions.
I thought I had 2 yards of 60" wide shirting.  I had 1.5 yards of 44" shirting.  Although the gown wasn't as short as the pattern envelope, DD and I were not comfortable with the length.  I added a bottom band in blue and white sprigged calico.  I might get a picture of that later.

Notes to self:
  • All: raise neck edge 1" on body and sleeves, 25" neck elastic, fold and press 1.25" to inside, sew 15/16" from folded edge (leaving 2" opening), insert 3/4" elastic.
  • Summer: lawn or shirting, 40" long, 6" sleeves (before hemming), 2.5 yds, hemmed sleeves (no elastic)
  • Winter: flannel, 48" long, 20" sleeves (before hemming), 3.5 yds, 9" sleeve elastic
