Non Vox populi

I liked Vox.com when it came out. The card format is cool, and the detailed yet bare-bones explainers suit my approach to many aspects of news: tell me what I need to know to understand this situation.

At first, I found the decision not to host comments interesting, but not alarming. After all, everyone knows that the Internet comments section is a bubbling cesspool, right?

But I’ve been reading Vox articles now for awhile, and I’ve noticed in too many cases, when they were just blowing it: incorrect or out-of-context facts, telling one half of an argument, or missing a crucial detail. And these are the kinds of things where a letter to the editor, or a stream of informed comments, can really make an article much more useful. I notice this particularly when Vox writes about energy, a topic I have studied in depth.

Here’s an example of the sort of thing I’m talking about. In “Ignore the haters: electric cars really are greener,” they cite a new Union of Concerned Scientists report at length. But they never mention that UCS is primarily an advocacy organization, not a research one. Or that, for example, Argonne National Labs has been publishing similar research for years with similar, but with slightly more muted results. Or even that the summary in the UCS report compares EVs against normal gasoline cars, which is hardly a like-vs-like comparison, given that gasoline vehicles execute a range of missions that EVs currently cannot. As it turns out, a PHEV or even a regular hybrid does in fact outperform an EV on CO2/mile in many parts of the country, and the data in the UCS report show it. And there are additional embedded assumptions, like that the electric grid will continue to get greener. That’s probably true, but maybe not, the greening of the grid could accelerate or it could start hitting hurdles that slow it down. At the same time gasoline cars could get better or worse. Hybrids might become the norm, lower carbon fuels could become mainstream, etc. Finally, EVs cost a lot more than gas cars. For the same money, could you reduce your carbon intensity more effectively than by buying an EV? (Answer: yes.) In the end, it’s hardly journalistic to lump everyone who has questions about the superiority of EV’s as a hater.

Getting back to Vox, it’s not just the bias that I don’t like. After all, bias is a part of journalism as organic chemistry is part of life. There’s no ombudsman, there’s no straightforward place to look for corrections. (They integrate corrections directly into cards, usually by changing the text without any notation.) The whole site is a Read Only Memory. In Ezra Klein’s own words on leaving the WP to found Vox: “we were held back, not just by the technology, but by the culture of journalism.”

Indeed. So, this is the improved technology and improved culture? It’s seriously starting to turn me off. Anybody else?

Garbage can strikes again

When I was in policy school, we learned about something called the “Garbage Can Model of Organizational Choice,” which for some reason has stuck with me. I don’t want to boil it down too much, but in it, Cohen, March, and Olson (and later, Kingdon) theorize that people are constantly coming up with “solutions” that more or less end up in a theoretical trash bin. Except, nobody ever empties the trash. Instead, it lingers. At the same time, the random stochastic process known as life generates a constant stream of problems. Every once in awhile, a “problem” comes along that fits a “solution” waiting in the trash can, and if there’s an actor who favors that solution who has been paying attention and waiting patiently, he trots it out and starts flogging hard.

In light of the Paris attacks, we’ve been seeing this from the security establishment in a big way. They like tools that let them see and watch everything, and they do not like anything that gets in their way. So, for example, banning encryption that they cannot defeat is a solution that sits in the trash can perpetually. That’s why it’s unsurprising that the ex-CIA director is calling for Edward Snowden’s hanging or Dianne Feinstein and other senators are railing against Silicon Valley for offering its users strong encryption.

It’s all about having an established agenda and seizing an opportunity when it comes along. Politics as usual, move along, these droids are not particularly interesting.

But there is actually something a bit interesting going on here. The actual facts and circumstances right now do not support the panopticon theory of governance favored by intelligence and law & order types. The terrorists in this case did not use encryption. They sent each other SMS and other messages completely in the clear. If you look in the Internet, you will find article after article debunking the notion that controls on encryption would have made a difference in these attacks at all.

In fact, given the circumstances of this particular case, it looks like the intelligence agencies already had all the tools they needed to stop this attack. They just didn’t. This, if anything, should be the actual story of the day!

Okay, so this is perhaps also not interesting to the jaded news junky. Maybe it’s a bit further down in the playbook, but we’ve all seen people who should be on the defensive go on the offensive in a big, loud way. But I still find it disturbing that the facts are not steering the debate at all. If you enjoy making fun of fact-free conservatives, then this is not the circus for you, either, as powerful Dems are behind this crap.

Various media outlets, even mainstream ones, are calling out the bullshit, but the bullshit continues.

Same as it ever was, or new, disturbing political discourse untethered to reality. You decide.

Oh, and just as an aside: you can’t stop the bad guys from using strong encryption. So what are you actually calling for?

Un-American Things

Barack Obama and Ted Cruz are currently having a bit of a one-sided insult match in response to the president suggesting that rejecting Syrian refugees, or only letting in refugees in who meed certain religious criteria, is un-American.

You won’t be surprised to hear that I think The President is right, of course. Our highest ideals are of opportunity and openness, and I think we all want to live in a country that is the destination for those in need to rebuild lives shattered through forces beyond their control.

But the president is also right in another way that I think is interesting. This country does not have a culture of risk-aversion. Or at least it doesn’t regarding most new things. I mean, let’s grant for the moment that letting in Syrian refugees means we are opening ourselves to some non-zero incremental risk of violence. Why shouldn’t we take that risk? We’re risk takers.

This is not a country that adopts the precautionary principle to food and environmental regulation. We don’t stop Uber and Airbnb before they get started because they might be unsafe. Nobody (federally) says, “sure, you can have a gun, after you show us you can handle it safely.” You want to use some new chemical you just invented in your industrial process? Have at it (generally), until we know it’s dangerous. So it goes. Nuclear power, moon exploration, homesteading the West. In the cases where we do have regulation, I think you’ll find 100% of the time that it came after something bad happened regarding the very thing being regulated.

And I think that’s more or less a fine, and certainly, very American philosophy. We’ve had some very bad outcomes here and there (leaded gas), but on average, the risks have worked out in our favor and we get more benefit than harm. In the case of Syrian refugees its a question of compromising our ideals to gain a little safety. Totally un-American.

What the other guys believe

How well do you understand the beliefs of those at the opposite political spectrum as yourself?

Being a semiprofessional policy nerd, so I thought I had a good handle on this. I know, for example, most of the conservative and liberal arguments for this or that policy proposal, and can (and do) rank them on their credibility all the time, constantly adjusting those rankings as I learn more about the world. That’s a wonk’s life.

But here’s a different question: which of those arguments do they believe and feel are the most compelling?

Some JMU researchers have devised a little experiment to determine just that. It’s a short questionnaire. You should take it! They ask you a few questions about the best policy arguments from conservative and liberal viewpoints and then they ask you your own political orientation.

I learned something from my results. I was able to correctly identify the favored argument of political conservatives approximately zero percent of the time. 0 for 5!

Paul Krugman thinks liberals understand conservative reasoning better than conservatives do liberal reasoning. Well, he might be true with respect to the logic of the arguments, but at least for this guy, he’s dead wrong regarding the beliefs about the strengths of the arguments.

h/t Baseline Scenario

Throwaway knowledge

I was recently tasked with writing an pretty useful extension for Chrome that would enhance Google Calendar so that room numbers on our campus would show links that would take you to campus’s internal map tool. Google Maps does not understand this campus, so the normal map link provided is not helpful.

This task took me the better part of a day and a half, and the whole time I was gripped by this awful feeling that in order to solve this simple problem, I had to learn a bunch of random stuff that would be mostly useless as soon as I was done.

For example, I needed to learn how Chrome extensions work. For that, I needed to familiarize myself with the Google Chrome API — at least enough to get this job done. I can say for sure that even in the small amount of time I spent on that task, I could tell that this API is not stable. They change it as often as they feel like, adding this, removing that, and most ominously “deprecating” some other things. Depracation is the worse. It means “we’re not taking this function way today, but we are taking it away, probably when you least expect it.” And, in any case, how many Chrome extensions is the average programmer going to write?

Furthermore, getting into Google Calendar enough to insert my links was an exercise in pure disposable hackery. I had to reverse engineer enough of Calendar to figure out where to scan for locations and where to insert links. And I needed to understand how Calendar works well enough to know when it is going to change up the document model and set event handlers for that.

This script works today, but it’s obviously going to break, probably very soon, because Google can and will change the internal guts of Calendar whenever they please. Unlike the extension API mentioned above, they are under no obligation, not even an twinge of guilt, to hold their internal implementation of Calendar to some fixed standard.

All this points to some rather sad facts about the future of coding for the web. You’ll absolutely have to work through the supported APIs, and when they change, that’s your problem, and if they are not offered or are incomplete, that’s also your problem, and if they go away, also your problem. Compare that, for example, to a piece of software on your PC. Maybe you wrote an ancient MSDOS .bat file that does something with the input and output of an old program you liked. If the company that made the program makes a new version that breaks your script, you could upgrade to it when you want to — or never, depending on what was convenient for you.

I’ve already been bitten by this. I made an alarm clock that interfaces with Google Calendar using a published API. It is a nice alarm clock with a mechanical chime handmade by hippies from Woodstock, NY. It worked, just fine for years, until, one day, it stopped working. Google had deprecated, and then dropped the API the clock was using. There was a new API. I had to go to my years-old code and rewrite it (to use a substantially more complicated API, by the way).

I guess that’s life, but people who make alarm clocks for a living may be surprised that users want them to provide active support and software upgrades forever. Or maybe we’ll just throw out our clocks after a year or so, like a phone.

But this is a mere annoyance compared to my main concern: unstable platforms discourage the development of knowledge and expertise. Why learn anything well if the entire API, or hell, the only supported programming language, or even the entire theoretical framework for working with the API (does anybody seriously think REST with PUT, GET, and POST is going to last forever?) is going to change next Wednesday? Perhaps that’s why in my interviews with Google nobody ever seemed to care one whit about any of my knowledge of experience.

I, for one, welcome the coming generations of ADD-afflicted software engineers and am excited to see the wagonloads of new “wheels” they’ll invent.

Yippee!

Leave it in the ground

About a decade ago, Alex Farrell, a professor in the UC Berkeley Energy and Resources Department, Alex Farrell, had a series of papers unpopular with environmentalists. They showed that, essentially, there was no peak oil. In fact, at prevailing prices of the time, one could profitably extract a supply of petroleum to last hundreds of years at current rates. The supply would come not just from traditional sources, but from Canadian bitumen and coal-to-liquids conversion. He also pointed out that this is a bad thing, because those alternative sources of petroleum products have ridiculously high carbon intensities. That is, they’d be much, much dirtier than regular oil.

Sadly, Professor Farrell did not live to see the story of peak oil fade from most environmentalists’ consciousness nor to see the price of oil has drop so dramatically. And, in fact, at today’s prevailing prices, influenced by fracking and cheap natural gas (which is not a short term substitute for oil but could be a long-term one), we just don’t need oil from the Canadian tar sands. There’s not really a strong economic case for it, and the environmental case is, well, awful. I guess there is still a story to be told about “continental oil independence,” but, well, that’s only physical independence. Unless we plan on declaring a state of emergency and militarily controlling oil transfer, oil is still a worldwide commodity, and if there were some kind of oil crunch, we’d take the economic gut punch all the same.

I think Obama made the correct decision today, to nix the Keystone Pipeline.

Score one for common sense.

Back when computers were computers

Trying to learn new tricks, this old dog dove into Amazon Lambda today. Distributed, cloud-based programming is really something to wrap your head around if you grew up working “a computer” where most if not all the moving parts you needed to make your program run were on that computer. Well, that’s not how the kids are doing it these days.

So Lambda is cool because you only have to write functions and everything about being a computer: setting it up, maintaining it, and provisioning more as needed is abstracted away and handled automatically. But that does come at a price: your functions need to be completely and 100% stateless. Hmm, all that fancy automatic provisioning and teardown seems a bit less impressive in that context.

To tie all those functions into what we used to call “a program” you still need state, and you get that from the usual suspects: , S3 or a database of your choosing, DropBox, whatever.

Which, to me seems like actually, all that provisioning and scaling mumbo jumbo is not handled automagically at all. You still need to think about your database, how many copies you need to X transactions per second, etc. Except now you’re using a database when you might have merely declared a variable which would be stored in, you know, memory as long as the program was running.

So now everything is way more complex and about a metric gajillion times slower.

But this is the cost, I guess, of the future, where every application is designed to support 100 million users. I think it makes great sense for applications where those 100 million users’ data is interacting with each other. But for old-skool apps, where you’re working with your own data most of the time (ie, editing a doc) I’d much rather write code for “a computer.”

Why I’m usually happy when iniatives fail

San Francisco’s anti-Airbnb measure (F) went down last night. So did another ballot measure (I) that would have put a moratorium on the construction of new housing in the Mission. The commentators on KQED this morning were calling it a failure for the progressives and a win for Airbnb, which spent millions to stop F.

Eh, maybe. I like to think of it as perhaps the electorate realizing that in general ballot measures are blunt tools that tend to offer simple (and wrong) answers to complex problems. Sometimes those answers directly benefit the individuals or organizations that sponsored the measure, at the expense of everyone else.

I’m not saying that the housing situation in SF is great and does not need to be addressed. It does, but I don’t think I know how to address it, and those measures certainly were half-cooked. I’m not even opposed to trying out half-cooked ideas when a situation is dire. But I’d like to see those experiments tried out by city councils and state legislatures that can, you know, augment, amplify, or reverse them as results come in.

Of course, legislative bodies often don’t act fast enough or decisively enough for many of us. It’s worth taxonomizing why that might be:

the legislators do not care
the legislators are bought off by bad guys
the legislators think other issues must take precedence
the legislators do not understand an issue well enough to craft a solution (note: they have staffs and experts at their disposal. What do you know that they do not?)
legislators believe that something you think is a problem is not actually a problem
legislators consider factors about which you don’t care
none of the proposed solutions could garner a majority

We could go on, but I guess my point is that the initiative process was designed to deal with a legislature that seemed to be at odds with the electorate. Seemed is a strong word. There was good evidence it was so. But more often, I think some of those other explanations are in play, and vote accordingly.

Racket of the day: higher education

A professor at Cal State Fullerton is in trouble for assigning a cheaper textbook than the one assigned by his department. The department-chosen text retails for a whopping $180. It’s also worth noting that the $180 textbook was written by the chair and vice chair of the math department.

Aside from unfortunate conflict of interest, one has to step back and wonder why it is that textbooks are so expensive these days. Has the cost of publishing gone up significantly? Prices in the rest of the book industry would seem to indicate not. Is it harder to recruit authors than ever? Maybe, but it’s worth pointing out that there’s probably not much that has changed in an introductory linear algebra text in the past 50 years.

The only explanation I can’t bat away is that the educational publishing industry learned to assert market power. The students have to buy the course textbook, and that gives publishers who can get in the door strong pricing flexibility, better yet if they are in cahoots with the administration. Furthermore, the ability to pay is bolstered by our good friends, non-dischargeable student loans.

It’s embarassing and sad. One could imagine an alternative universe where a system like Cal State endeavors to create its own teaching materials for free or minimal cost. It’s not like their are a dearth of linear algebra resources for free on the web. But that is not our world.

Finally, as a point of comparison, it just so happens that I still have my linear algebra textbook from undergrad.

Linear Algebra for Calculus, K. Heuvers, J. Kuisti, et al.

$13.35 in 1992 would be $22.64 today. Amazon lists the current edition today for $111. Hmm.

Falling out of love with Silicon Valley

I came to Silicon Valley in the mid 1990’s. Reflecting back on that time directly out of college, I remember that I thought computer chips were exciting and that the best companies designing and manufacturing them were making huge money. Of course, I had been fascinated with computers since I was little, as had many of my coworkers.

Anyway, computer chips seemed really cool back then. They looked cool. They were made in cool manufacturing environments. The tools to design them were cool. And the chips were getting better and faster all the time. Honestly, it just seemed like fun and I wanted in.

In those years, I distinctly remember social events where I would try to express my excitement about semiconductors and folks would just politely back away from me, the crazy nerd.

Today, Silicon Valley is still cool. In fact, it’s way cooler and more widely cool. People are making even more money, more people are involved, and the products they’re churning out are used by more people and in more numerous ways. And, the only reason you can’t talk about your work at parties today is because everyone is so tired of it.

But, SV today leaves me cold.

What has changed is cool itself. I liked nerd-cool, but this is mainstream capitalist cool. Banker cool. “Kids” in hoodies cool. Ignore the rules cool.

The people being drawn to Silicon Valley today, like me, are also coming because it’s exciting, but what excites them is not the same as what excited me. For awhile I thought this was a software vs. hardware thing. (It is, but not entirely — requires a separate post for sure.)

I see two basic factors for my loss of affection for SV:

Today’s hot companies generally deploy tech rather than make it. The exceptions seem to be when they have to develop something for operational purposes, and when they do they seem to keep their innovations close. Poster child for this might be Google, which had to invent a lot of its infrastructure, though a Google starting fresh today would probably have much less to do. Anyway, not creating things you don’t absolutely have to create is probably smart, but can we admit that it’s also boring?
The business models make me uncomfortable. Making a thing (or software, or a service) and selling it in a two-party, pareto-improving transaction is very passé. In fact, if your plan is to make and sell hardware OR software, your prospects for raising money are limited. Instead, advertising and market-making are hot.

When I was a young man, choosing my major in college, there were large, successful advertising businesses and large, successful market makers. But I would never have spent a femtosecond considering working for either.

Today, advertisers (Google, Facebook, etc) and market-makers (Uber, Airbnb, etc) dominate Silicon Valley. They’re great companies, I guess, but I have to wonder why so many engineers are thrilled to join them. Steve Jobs once famously recruited John Sculley by asking him if he wanted to sell sugar water for the rest of his career, or if he wanted to change the world. Well, it seems that sugar water (or perhaps, sugar water once removed) may have actually won in the end. (Interestingly, Apple continues to mostly avoid this model.)

I still love tech. Maybe the tech nerds will regroup somewhere and stage a comeback. Probably not going to happen in SV, though.
