LaTeX notes

I recently installed a plugin that will allow me to render LaTeX. Mostly this is because I’ve long avoided writing out equations because it’s awkward in HTML, and it gets unintelligible quickly. This will allow me to explore population genetics in its “natural language” a little easier.

But I just noticed on my RSS feed view the LaTeX is not rendering for whatever reason. Where there should be equations or LaTeX rendered text there is a blank space. This is unfortunate, but I don’t know what to do about it. So just click through if you want the equations. If you are willing to “hum through” those portions it shouldn’t matter. The equations aren’t going to take up much of any post.

Also, Donald Knuth is a god. Probably he’ll think that’s blasphemous because he’s a Lutheran and all, but The Art of Computer Programming beats the Bible in my book!

The reader survey now N > 300. I assume it will stabilize in the next few weeks in the 400s.

So far the biggest surprise that I’ve noticed is the ratio of married to divorced; 14o to 9. But, this aligns with research that college educated people do not get divorced at a high rate, and more than 50% of my readership has completed graduate educations, so the sample is probably even more biased.

In France it is Marcon vs. Le Pen for the second round it seems. It seems likely Marcon will win the second round…but I do wonder if some far Left voters will refuse to vote for a candidate is a pretty transparent avatar of the globalist elite.

I love California, but, In costly Bay Area, even six-figure salaries are considered ‘low income’:

San Francisco and San Mateo counties have the highest limits in the Bay Area — and among the highest such numbers in the country. A family of four with an income of $105,350 per year is considered “low income.” A $65,800 annual income is considered “very low” for a family the same size, and $39,500 is “extremely low.” The median income for those areas is $115,300.

The problem many, but not all, Lefties in this part of the country have is their rhetoric is always about making housing affordable, not making more housing (which would naturally lead to more affordability).

I was a bit surprised how few readers had read Matt Ridley’s Genome: The Autobiography of a Species in 23 Chapters. I’d highly recommend it.

A new wave of GSS data is out. Might start some GSS blogging again.

Maybe moderate drinking isn’t so good for you after all:

But our latest research challenges this view. We found while moderate drinkers are healthier than relatively heavy drinkers or non-drinkers, they are also wealthier. When we control for the influence of wealth, then alcohol’s apparent health benefit is much reduced in women aged 50 years or older, and disappears completely in men of similar age.

People I know had long warned these were observational studies. But perhaps I run with a strange crowd….

2017 Gene Expression reader survey


Since I’m finally getting settled in here, I thought it was a good time to do a reader survey: https://www.surveymonkey.com/r/MW3YFZH.

So it’s open. You can only take it once, but it shouldn’t take more than a few minutes. There are 30 questions but the first 20 are mostly demographic and should go very quickly (e.g., your age, your sex, your race), and the last 10 are not difficult either (if you don’t know if you are a deontologist or consequentalist on ethics, don’t answer). Many are now of the form where you can answer more than one option.

I basically took the template of last year’s survey, made several changes, removing some questions and adding some. Also, I stole a few from Slate Star Codex.

You can read the non-text answers of the 2016 survey here.

In the middle of May I will the raw data (no-IP) and post it here so others can analyze if they want.

Addendum 1: Since I don’t know where else to put this, I have noticed an increase in referrals through my Amazon links. So that’s much appreciated. Obviously I’m not really getting paid much for blogging or doing the sysadmin activities, but it’s definitely going to covering overages from VPS traffic or anything like that. Remember, even if you don’t buy directly through the link I still get a referral if you are on Amazon during a session and buy something different.

Addendum 2: Forgot to mention. I’ve been doing reader surveys since 2004. The final tally of the number of people who fill the survey is always between 300 and 500, invariant of how much traffic I received (my traffic has varied about an order of magnitude over the years). It is curious to me that this “core readership” (as I perceive it) is about the same size as a Roman cohort.

Only half of the traffic on this website is from a personal ‘computer’

I spend way too much time semi-competently managing the VPS this site is hosted on. But at least now I can look at Google Analytics. I’ve found some interesting things.

For example, 35% of the traffic on this site comes from phones, and 10% from tablets. That means that conventional computers are only somewhat more than half of the views. Additionally, 50% more of the Facebook shares are via the mobile Facebook app than the normal desktop version (I tend to get the most referrals from Twitter since I have a bigger Twitter following, but at some point I expect Facebook to surpass that as people realize I’m blogging again).

Probably going to make a few changes to make the site more mobile friendly since so many of you tend to read it on that device….

Happy Easter. Spend most of the day figuring out how to restart Varnish. I don’t really know why there are so many database connection problems and caching…but I inherited the VPS. Might have to bone up on being a sysadmin more. Do any readers know if Varnish is really worth a modest site like mine?

Erdogan Claims Vast New Powers After Narrow Victory in Turkish Referendum. First, I have to say that The Future of Freedom: Illiberal Democracy at Home and Abroad is pretty relevant today. Second, Erdogan has shown many faces to the world over the past 15 years. I remember for example him telling people in post-Arab Spring Tunisia that in a free society atheism is a real option (to some criticism).

Are 90% of academic papers really never cited? Reviewing the literature on academic citations. It’s really a problem in the humanities:

Many academic articles are never cited, although I could not find any study with a result as high as 90%. Non-citation rates vary enormously by field. “Only” 12% of medicine articles are not cited, compared to about 82% (!) for the humanities. It’s 27% for natural sciences and 32% for social sciences (cite). For everything except humanities, those numbers are far from 90% but they are still high: One third of social science articles go uncited! Ten points for academia’s critics. Before we slash humanities departments, though, remember that much of their most prestigious research is published in books. On the other hand, at least in literature, many books are rarely cited too.

White supremacist who created stir at Stanislaus State seen punching woman at Berkeley protest. First, please note that this woman went to the protest to get “Nazi scalps” according to her social media. Second, the image of a white supremacist punching an anti-fascist woman is exactly what Sarah Haider told me was going to be a problem with contemporary Leftist valorization of violence: Left-wing organizations have proportionally many more women than right-wing militant organizations, which isn’t an asset in pitched physical combat.

This website is wicked popular in Boston

Weird pattern in terms of top cities that read this new version of GNXP. I’m comparing to the old blog over the same time…most of that is search engine traffic, so it’s not totally representative. The Australian overrepresentation is strange to me but it may be some Australian focused blog posts were promoted on some site down under. As search engine traffic increases on this website I’m assuming New York will be taking the top slot….

Roger Lowenstein’s When Genius Failed: The Rise and Fall of Long-Term Capital Management was influential in turning me against naive market libertarianism. Market can correct for errors, but when that takes the whole global economy down…. (also, hedge fund guys are genuine assholes who don’t give a shit in many cases)

Why ISIS Declared War on Egypt’s Christians. An analogy here is made to Shia in Iraq. The analogy breaks down because the Shia Arabs of Iraq are about half the population. Coptic Christians are closer to 10%. Because Egypt has a large population there are probably more than 5 million Coptic Christians. Mass migrations as occurred with Iraqi Christian can’t work because there are too many of them.

California is getting so much power from solar that wholesale electricity prices are turning negative. Not surprising if you read Ramez Naam’s The Infinite Resource: The Power of Ideas on a Finite Planet.

UC Berkeley Was Warned About Its Star Professor Years Before Sexual Harassment Lawsuit. Searle is rightly famous. His ideas may have merit even if he is a horrible person. And for all the moral panic about sexual assaults on campus between undergraduates, one thing you notice if you are in academia is there are a well known list of creepy professors who you hear about, but who are too famous and powerful to confront unless they really, really, step over the line, or, someone is willing to stake their reputation and career on a take-down.

An updated meta-analysis of the ego depletion effect. A big deal. Probably true.

This thread illustrates that New York City consists of three broad groups of people:

1) The affluent, from young finance professionals to the Upper East Side wealthy.

2) The transient. This includes young artists and creative types who live relatively cheap and have few expenses, and will probably move on as they mature, either into another field that pays better, or, to a region they can afford. It also includes immigrants who are just starting out in this country. By the second and third generation many of their children and grandchildren will be moving out of the city.

3) The permanent poor. See the Bronx.

Pizza chains are making a desperate push to avoid posting calories on menus. Have you seen how many calories are in one slice?

Two issues with this blog. First, lots of problems with connecting to the MySQL database. A quick hack is that I wrote a script which checks if the database is down every 5 seconds and restarts it if it’s down. Also, lots of 503 errors, probably because of a caching problem. I’ll fix this, but if you have advice, appreciate.

Also, I’m loading the full archives of my content right now. It might be disorganized, but all of it should be searchable soon(ish).

On monetizing this website

For ten years I have not given much thought to monetization of this weblog. Other people took care of that for me.

The upside of running my own ship is obvious in terms of control. The downside is I’m now my own sysadmin, and I’m not getting paid to do that (not to mention hosting, etc.).

For over a decade I’ve also been an Amazon Associate. When I put up book reviews I link to Amazon, and if you buy the book I get a cut. But, another aspect of this is that the referral session stays active even if you use Amazon to purchase something else.

I’ve been rather passive about this so far, but now I’ve decided to put a link to my Amazon associates page on the top right. If you click through that link and buy something at Amazon I get a cut. This isn’t trivial when it comes to big ticket items. Anyway, I would appreciate if long time readers were conscious of this.

I know many of my readers buy from Amazon anyway, so it’s a way to support me generating this sort of content for “free” in the normal course of things.

What should I blog about in the next two weeks?

Any thoughts/suggestions? Only thing off limits would be anything too personal. I already asked on Twitter and got some responses so no need to be redundant unless you want to add to the weight of a preference.

Also, now that I finished Reformations* I’m finally reading Nick Bostrom’s Superintelligence front to back. But I have a lot of other Kindle books in the “stack”, and aside from those I’m going to tackle for personal/professional development (e.g., stuff on machine learning or Bayesian statistics) I have some latitude and am toying with listing books and giving readers some input in the arrangement/sequence.

* I’ll review the book at some point, but main quibble is that it was too heavy on ideas/theology, even though by the end the author admitted one should be cautious about focusing on this aspect.

23andMe

One of the stranger call-ins on my interview with Kathleen Dunn last month was when a woman who proudly declared that she was a math major in college asserted that 23andMe had told her she wasn’t at risk for many diseases which now in her 60s she had developed. I didn’t want to be too pointed about it, but if you are in your 60s you are at risk for developing many illnesses no matter what your “genetic risk.” This is clear from 23andMe’s statistics, which display high baseline risks for many common diseases. From reading comments on 23andMe discussion forums it seems that perceived false negatives are going to be a much bigger issue than false positives over the long run. If the tests are “wrong” in a direction which leaves you in a better state than predicted you might feel like you’ve dodged a bullet. On other hand if the tests are “wrong” in a direction which gave you false comfort, or add insult to injury when you’ve developed a debilitating disease, then you feel much more burned.

I don’t really recommend blogs too much anymore. But please check out The Stage and Social Evolution Forum.
