Moving On A Sphere

You know what are kind of like circles, except cooler? Spheres. Our lovely planet Earth, of course, is an oblate spheroid, a fact I will completely ignore for now. From time to time, I have need to move things around an area of about 3,000 square kilometers. That’s a small enough patch of Earth’s surface to use a system of easting and northing, which is measured in kilometers. GPS position coordinates are in degrees latitude and longitude.

Something Subjectively Beautiful: 15/01/2012

There hasn’t been any bizarre tinkering or craftiness in the past week, so I decided it was time for another example of Something Subjectively Beautiful. This might also qualify as a Self-Promotion Sunday since I guess I did take the photographs, but I’m less interested in the quality of the photography as I am in the quality of the really awesome nature stuff depicted therein.

Coffe Brewing Method #4

Personally, I have made coffee four different ways. Naturally, as an American I have used an auto-drip machine. My coffee brewing workhorse has always been a french press, though. I think it makes a better tasting coffee, especially compared to auto-drip in small quantities. As a wedding gift, someone gave me a moka pot, with which I have made exactly one fantastic cup of coffee which I have never been able to reproduce.

Now I’ve decided to try one of those cone things they sell at the grocery store next to the coffee filters for $5. Why not? It’s easily obtainable, at least some coffee snobs rave over them, and it will make a single serving of coffee. With these on the market, I don’t understand how those $100 single cup drip machines survive.

I am not the authority on canonically good coffee, but I can tell you what I like. The few times I’ve used mine so far have all turned out very nicely. One thing to keep track of is how fast you pour the water. If a lot starts to pool up, grounds can get deposited on the side of the cone where they don’t really see much water once it starts to drain. This probably over-extracts the grounds left at the bottom of the cone.

Overall, I’ll call it a success. The coffee produced was at least as palatable to me as my usual french press ritual. Keep in mind I don’t measure my coffee out by weight. I squint at it, shrug and toss it in when it looks right. However, I do grind my beans fresh and usually use single origin. With the success of the pour-over method I’m trying to cut back a little on my coffee consumption, so this will probably replace the 8-cup french press in my office.

Dear Combatants, I Grow Weary

Yes. I’m going there again, to that atheist/skeptic gender war thing. I promise that unless I receive any direct provocation after this I will resign to be but a bystander not offering any more commentary. Even now I’m going to try to step as far back as I can. There is a relatively popular blog that I really think skeptics should read, You Are Not So Smart. The author has an acerbic wit about him that makes Brian Dunning look cuddly in comparison.

Of particular note are articles on The Backfire Effect and Deindividualization. Honestly, The Illusion of Asymmetric Insight might even be relevant–it’s at least really interesting, at least I thought so. To boil it down to my own dry interpretation, I think it is really important for skeptics to understand how their brain works and what kinds of tricks it will play on us when we think we’re being completely reasonable. All the logical fallacy flashcards in the world will stop us from falling into one from time to time.

Importantly, being aware of something does not put us above it. If we acknowledge sexism as a problem, that does not mean we cannot be sexist. I proudly call myself a feminist, and if in company that doesn’t like to apply the word to men, I will with equal pride call my self a feminist ally. But you know what? I’m still going to say and do sexist things. Racist things, too. Just because I am aware of my white, male, cisgendered, class privilege does not mean I cannot or will not make mistakes.

When I do make mistakes, sometimes I catch myself, sometimes it passes unnoticed by me, and sometimes people call me out on it. Can you guess what the first thing I think when I get called out is? “Nuh uh!” Sometimes that’s my second, third, fourth thought, and so on. No matter how wrong we are, being corrected stings. Only one thing, so far as I am aware, can help us–being aware of the possibility that we can slip up.

Knowing about each of our own privileges and pitfalls doesn’t inoculate us against acting them out or falling into them. We have to be aware. To be the best person I can be I have to keep it in my head that I can be unfair. I have to remember that even though it feels like a slight when someone tells me how something I said or did upset them, I shouldn’t immediately bite back. Even though I think I can justify my transgression, the most important thing is making sure I treat the people around me the way they deserve to be treated–with kindness and respect.

It’s a lot to do. And we probably won’t do it perfectly or even gracefully every time. But the really beautiful thing is that if you try, people will understand in the end. Also, I don’t think this is limited to the  way we should treat people inside our own movement. To be honest, I don’t think I ever would have personally gravitated toward skepticism or atheism were I not already on a trajectory heading that way. The language frequently used to discuss the direct objects of our skepticism will probably earn high fives from the skeptics, but not much good from the general public.

Silver Ribbons: The Internet Can Be Nice

I had never heard of the silver ribbon before The Bloggess posted about her fight with depression. There was, as you can see for yourselves, an outpouring of support in the comments. I had also just seen Allie’s story of depression on Hyperbole and a Half, and been linked to it a few times. Maria at Skepchick gave a shout-out of support, told her own story, and set up a tumbler for people to anonymously tell their own.

This is amazing. People. Are. Being. Nice…. On the Internet. If people haven’t had to cope with depression themselves, they’ve had a loved one who has. And everyone seems to agree that the stigma is wrong and the mentally ill deserve kindness and support. I know the it’s all their fault mental illness deniers are out there somewhere, but they’ve either been drowned out by the supporters or the bloggers are waging a seriously intense moderation campaign. The simple fact that they have not co-opted this trend fills me with cool, fizzy, refreshing hope.

So I’m going to tell a really quick story. I have my first dentist appointment in years tomorrow morning. This morning I got the usual reminder phone call and was instructed to bring the names of any medications I take and the dosage. When I answer this question, almost without fail,  I get a look. The look ranges from pity to contempt to fear. It lasts a second, maybe less, but it can affect my mood for weeks afterward. And it comes from a medical professional, someone I feel like I should be able to trust not to judge me. It really does feel like a betrayal.

Self-Promotion Sunday: Stayin’ Alive

I feel really awkward promoting myself. Especially on the internet, even if it’s only nominally to friends and family. It feels like being a brand instead of a person, so I generally try to avoid it. Unless I did something really cool. This is my attempt to lower the bar a little bit and celebrate something stupid I did this afternoon: get an Arduino Uno microcontroller to screech Stayin’ Alive on a piezo speaker. Badly.

You can, in part, thank my wife (who writes an actually interesting Tumblr blog called Domestic Disasters) for getting me the Sparkfun Arduino Inventors Kit for [insert solstice holiday here]. Also, note the cameo appearance of Oliver Snuggles, who will sleep through anything unless it would be an inconvenience to have a cat climbing on you. I’ll report back if I do anything else that amuses me.

Large Numbers are Confusing

Large numbers are confusing, because most people don’t have a reference from their everyday life to help them make a connection to what the number actually means in a context they can understand. Actually, even when you work with big numbers for a living there’s a very limited scope where understanding holds together.

In my own little niche of cosmic ray physics we routinely deal with the energy spectrum of ultra high energy cosmic rays, shown in the plot. On the right side of the energy axis are numbers on the order of 10^{18} electron volts, that’s one with 18 zeros, or one Exa-electron-volt. Down at the bottom you’ll see a couple of tick marks indicating the energy of the old Tevatron at Fermilab and the LHC at Cern. Those are there to help people who might be familiar with particle physics but not particle astrophysics put the graph in context.

Even though I’m personally used to seeing those numbers, though, put them in an unfamiliar environment and I’d be just as lost as the next non-expert. An office mate of mine pointed out something while installing the Java Runtime Environment that got him thinking. The self-promoting installer popped up with interesting facts about Java, including a claim that it was installed on 30 million devices worldwide. One of Java’s selling points is that it runs on a virtual machine and should then work on just about any system including PCs, cell phones, game consoles, and DVR players.

He counted the number of devices he and his wife owned that would, in theory, be able to run Java: ten. Let’s assume that’s high for most people and say the average American owns about half as many such devices: about two. That would mean in the United States alone there would be about 600 million Java-capable devices. Which makes the claim of 30 million not seem so impressive, that’s about 5% of their potential US market.

This is, of course, a complete estimate. I liked thinking about it because it’s reminiscent of the classic Fermi Problems. So maybe there’s a reason why the original claim made by the installer really should impress me, but that might actually make my point even better–big numbers are confusing. 30 million is a big enough number that without context it sounds impressive simply because it’s so much bigger than the average two devices owned by the average American ;-)

Reddit Stats Analysis Code

I think I’m on record as thinking Reddit is worthless as a content discovery platform. For a while I still held on to using it because it was popular and somewhere in the sea of trash that was promoted to the front page there had to be interesting links. Even after using the Reddit Enhancement Suite to remove all links to imgur and quickmeme, my interest in continuing to use the service has expired.

Prior to that, though, I had planned on trying to find a sweet spot for tolerable subreddits. So I wrote some python code to use the Reddit API to fetch the top links from a list of subs that I picked to cover a variety of different sizes and topics to see if I could find any markers for what made a reddit enjoyable to me. After my patience waned, and especially after this incident occurred (albeit months later), I simply felt no desire to continue with the project.

In the event that anyone is interested in playing around with the code, here it is. The documentation is in some comments and I’ve included a sample output. To be entirely honest, I don’t understand the Reddit API and am probably not using it to it’s full effect. I also have no idea what to do with a .json file so I’m hacking around them in what is certainly the exact wrong way. You’ll probably also have to edit the python code to work (and have the scipy library installed) since I wrote it for my Arch Linux system.

It should spew out some interesting information about the number of unique domains in a given reddit, as well as the number of links to a particular domain. I also messed around with seeing how the total number upvotes given were distributed across all the top links. Give it a go if you’re interested–I’d definitely like to see results, I’m just not motivated to produce them myself.

Ongoing Battles in Gender Equality

If the internet were real life horses would be immortal. The phrase “beating a dead horse” means nothing, because the horses never die. Long after you’d think it should be gone, it just keeps going. Then the prevention of cruelty to digital animals activists show up, but somehow the beating just continue to no avail. A few people probably start using the digital horse advocates as further bludgeoning weapons. Ad infititum, the beatings go on.

I do not understand people or how they work, but as Jen will tell you, last night, some crap happened. Three words come to mind, the first is “false”. The other two are “dichotomy” and “equivalence”. The prevailing sentiments aside from those espoused by Jen and her co-conspirators (i.e. the right ones) seem to fall along the lines of “If I’m trying to speak for all of woman kind, then so are you!” and “When will women learn that they should just avoid situations in which they might be hurt?” Can I add another two words? How about “victim blaming”? Continue reading

Gender Equality in The Land of Skeptics

Sigh. So this past summer a notable skeptic blogger was made uncomfortable as a consequence of the way in which someone else behaved in an elevator. She did this while being a woman, mind you. Thus was born elevatorgate, the internet drama that will not die. If you don’t know what’s going on, I don’t know where you’ve been these past six months. You can Google it, catch up, and I’ll still be here.
