They are undertaking the redesign primarily to make flying around SFO quieter and more fuel efficient. The new shape will allow steeper descents at or near “flight idle” — meaning the planes can just sort of glide in, burning less gas and making less noise. As a side benefit, they will be able to raise the bottom of the airspace in certain places so that it is easier for aircraft not going to SFO to operate underneath.
As far as I’m concerned, that’s all good, but I noticed something interesting about the new and old design. Here’s the old design:
This picture, or one like it, will be familiar to most pilots. It’s a bunch of concentric circles with lines radiating out from it, dividing it into sectored rings. The numbers represent the top and bottom of those sections, in hundreds of feet. This is the classic “inverted wedding cake” of a Class B airspace. In 3D, it looks something like this, but more complicated.
This design was based around the VOR, a radio navigation system, that could tell you what azimuth (radial) you are relative to a fixed station, such as the VOR transmitter on the field at SFO. A second system, usually coupled with a VOR, called DME, allows you to know your distance from the station. Together, you can know your exact position, but because of this “polar coordinate” way of knowing your position, designs intended to be flown by VOR+DME tend to be made of slices and sectors of circles.
The new proposed design does away with this entirely.
Basically, they just drew lines any which way, wherever it made sense. This map is almost un-navigable by VOR and DME. It takes a lot of know twisting and fiddling to establish your exact position if it is not based on an arc or radial. Basically, this map is intended for aircraft with GPS.
All of this is well and good, I guess. GPS has been ubiquitous in every phone, every iPad and every pilot’s flight bag for a long time.
I learned to fly in a transitional era, when GPS existed, but the aircraft mostly had 2 VOR receivers and a DME. My flight instructor would never have let me use a GPS as a mean of primary navigation. Sure, for help, but I needed to be able to steer the plane without it, because the only “legal” navigation system in the plane were the VORs. I still feel a bit guilty when I just punch up “direct to” in my GPS and follow the purple line. It feels like cheating.
But it’s not, I guess. Time marches on. Today, new aircraft all have built-in GPS, but a lot of older ones don’t. And if they’re going to fly under the SFO Class B airspace, they’re going to need to use one of those iPads to know where they are relative to those airspace boundaries. And strictly, speaking, they probably should get panel-mounted GPS as well.
I grew up with computers. We got our first machine, an Atari 800, when I was only 8 or 9. An 8-bitter with hardware sprites. 48 KiB of memory, and a cassette tape trive, this was only one step removed from the Atari 2600 game console. Very nearly useless, this was a machine for enthusiasts and hobbyists.
Over time, computers became less useless, as well as more “user-friendly,” but they — particularly the PC style machines — kept the doors open to hobbyists and tinkerers.
The Bad News
I think, however, that that era has come to an end, and I’m saddened. I see three basic trends that have killed it.
The first is that the network-connected world is dangerous. You can’t just fire up any old executable you find on the Internet in order to see what it does. It might do something Awful.
The second is that the closed ecosystem app stores of the world, aiming for a super smooth experience, have raised the quality bar for participation — particularly for “polish.” You simply cannot publish ugly, but highly functional software today.
The third problem is that you can’t make interesting software today without interacting with several systems in the cloud. Your app, hosted on a server, talks to a database, another app, and a half dozen other APIs: a link shortener, a video encoder, etc. And these APIs change constantly. There is no commitment to backward compatibility — something that was an iron-clad requirement of the PC era.
Trend one is a painful fact of life. Trend two could be reversed if the manufacturers had any incentive to do so. They do not. Trend three, I think is the worse, because it is wholly unnecessary. Say what you want about the “Wintel duopoly,” but they did not punish developers like modern companies do.
Together, these things pretty much lock out the casual developer. I’ve learned this the hard way as I try to push forward in my free time with a few open-source apps in a post PC world. It is one thing for a paid programmer to maintain a piece of software and deal, however grudgingly, with every email that comes from Google telling you that you need to update your code, again. But the hobbyist who wrote something cool for his friends, that worked for six months and then broke, is kind of stuck. Does he want to run a zero-revenue company that “supports” his app in perpetuity?
Of course, if the PC, Mac, i-device, and household gadget becomes more and more locked off, there is an exciting antidote: Arduino, Raspberry Pi, Beaglebone, and the entire maker world. People are building cool stuff. It’s cheap, it’s fun, and the barriers to entry, though intellectually a bit higher than the “PC” are pretty damn low. Furthermore, the ecosystems around these products are refreshingly chaotic and more than slightly anti-corporate.
One of the nice things about this platforms is that they are self-contained and so pose little threat to data other than what you put on them. On the other hand, they are full-fledged computer and are as exploitable as any other.
If you make something cool that runs on a Raspberry Pi, there’s still pretty little chance every kid at school will soon have it and run it, but then again, maybe there never was.
Keeping up my streak of mildly entertaining, though basically useless Chrome Extensions, I have create a very tiny extension that keeps the Nate Silver fivethirtyeight predictions in your Chrome toolbar at all times.
You can choose which of Silver’s models is displayed, and clicking brings up more detail as well as links to a few other sites making predictions. Check it out!
For those who are interested in such things, the code is up on github. It’s actually a reasonably minimalist example of a “browser action” extension.
I’ve been bouncing around just at the edge of my 2016 presidential campaign overload limit, and the other night’s debate and associated post-debate blogging sent me right through it.
Yes, I was thrilled to see my preferred candidate (Hermione) outperform the other candidate (Wormtail), but all the post-debate analysis and gloating made me weary.
Then, I thought about the important issues facing this country, the ones that keep me up at night worrying for my kids, the ones that were not discussed in the debate, or if they were, only through buzzwords and hand waves, and I got depressed. Because there is precious little in the campaign that addresses them. (To be fair, Clinton’s platform touches on most of these, and Trump’s covers a few, though neither as clearly or candidly as I’d like.)
So, without further ado, I present my list of campaign issues I’d like to see discussed, live, in a debate. If you are a debate moderator from an alternate universe who has moved through an interdimensional portal to our universe, consider using some of these questions:
How do we deal with the employment effects of rapid technological change? File the effects of globalization under the same category, because technological change is a driver of that as well. I like technology and am excited about its many positive possibilities, but you don’t have to be a “Luddite” to say that it has already eliminated a lot of jobs and will eliminate many more. History has shown us that whenever technology takes away work, it eventually gives it back, but I have two issues with that. First, it is certainly possible that “this time it’s different. Second, and more worrisome, history also shows that the time gap between killing jobs and creating new ones can be multigenerational. Furthermore, it’s not clear that the same people who had the old jobs will be able to perform the new ones, even if they were immediately available.
This is a setup for an extended period of immiseration for working people. And, by the way, don’t think you’ll be immune to this because you’re a professional or because you’re in STEM. Efficiency is coming to your workplace.
It’s a big deal.
I don’t have a fantastic solution to offer, but HRC’s platform, without framing the issue just as I have, does include the idea of major infrastructure reinvestment, which could cushion this effect.
Bonus: how important should work be? Should every able person have/need a job? Why or why not?
Related to this is growing inequality. The technology is allowing fewer and fewer people to capture more and more surplus. Should we try to reverse that, and if so, how do we do so? Answering this means answering some very fundamental questions about what is fairness that I don’t think have been seriously broached.
Sanders built his campaign on this, and Clinton’s platform talks about economic justice, but certainly does not frame it so starkly.
What has been discussed, at least in the nerd blogosphere, are the deleterious effects of inequality: its (probably) corrosive effect on democracy as well as its challenge to the core belief that everyone gets a chance in America.
Do we try to reverse this or not, and if so, how?
Speaking of chances, our public education system has been an important, perhaps the important engine of upward mobility in the US. What are we going to do to strengthen our education system so that it continues to improve and serve everyone? This is an issue that spans preschool to university. Why are we systematically trying to defund, dismantle, weaken, and privatize these institutions? Related, how have our experiments in making education more efficient been working? What have we learned from them?
Justice. Is our society just and fair? Are we measuring it? Are we progressing? Are we counting everyone? Are people getting a fair shake? Is everyone getting equal treatment under the law?
I’m absolutely talking about racial justice here, but also gender, sexual orientation, economic, environmental, you name it.
If you think the current situation is just, how do you explain recent shootings, etc? If you think it is not just, how do you see fixing it? Top-down or bottom-up? What would you say to a large or even majority constituency that is less (or more) concerned about these issues than you yourself are?
Climate change. What can be done about it at this point, and what are we willing to do? Related, given that we are probably already seeing the effects of climate change, what can be done to help those adversely effected, and should we be doing anything to help them? Who are the beneficiaries of climate change or the processes that contribute to climate change, and should we transfer wealth to benefit those harmed? Should the scope of these questions extend internationally?
Rebuilding and protecting our physical infrastructure. I think both candidates actually agree on this, but I didn’t hear much about plans and scope. We have aging:
roads and bridges
air traffic control
What are we doing to modernize them, how much will it cost? What are the costs of not doing it? What are the barriers that are getting in the way of major upgrades of these infrastructures, and what are we going to do to overcome them?
Also, which of these can be hardened and protected, and at what cost? Should we attempt to do so?
Military power. What is it for, what are its limits? How will you decide when and how to deploy military power? Defending the US at home is pretty straightforward, but defending military interests abroad is a bit more complex.
Do the candidates have established doctrines that they intend follow? What do they think is possible to accomplish with US military power and what is not? What will trigger US military engagement? Under what circumstances do we disengage from a conflict? What do you think of the US’s record in military adventures and do you think that tells you anything about the types of problems we should try to solve using the US military?
7-a. Bonus. What can we do to stop nuclear proliferation in DPRK? Compare and contrast Iran and DPRK and various containment strategies that might be deployed.
I often think about how to preserve data. This is mostly driven by my photography habit. My pictures are not fantastic, but they mean a lot to me, and I suspect, but am by no means certain, that they will mean something to my children and grandchildren. I certainly would love to know what the lives of my own grandparents were like, to see them in stages of life parallel to my own. But I don’t know how to make sure my kids and their kids will be able to see these photos.
This is a super difficult problem. The physical media that the images are stored on (hard drives, flash cards, etc) degrade and will fail over time, and even if they don’t, the equipment to read that media will become scarce. Furthermore, the format of the data may become undecipherable over time as well. I have high confidence that it will be possible to read jpegs in the year 2056, but when you get into some more esoteric formats, I dunno.
A commonly proffered solution is to upload your data to a cloud service for backup. I have strong reservations about this as a method for long-term preservation. Those cloud backups are only good as long as the businesses that run them have some reason to continue to do so. Subscriptions, user accounts, and advertising driven revenue seem a poor match for permanent archival storage of anything. Who, long after I’m dead, is going to receive the email that says “your account will be closed if you do not update your credit card in 30 days”? Also, what good is a backup of data I can no longer view on my now-current quantum holographic AI companion?
All of this compares quite unfavorably with a common archival technique used for informal, family information: the shoe box. Photographs stored in a shoe box are susceptible to destruction by fire or flood, but they are fantastically resilient to general benign neglect over exceedingly long periods of time. Sure, the colors will fade if the box is left in a barn for 50 years, but, upon discovery, anyone can recognize the images using the mark-I human eyeball. (Furthermore, it’s really astounding how easy it is to use a computer to restore natural color to faded images.)
There is simply no analog to the shoe box full of negatives in today’s world. Sure, you can throw some flash memory cards into such a box, but you still have the readout problems mentioned above.
As people migrate from their first digital camera to their last digital camera to iPhoneN to iPhoneN+1, lots of images have already been lost. Because of the very short history of digital photography, you can’t even blame that loss on technological change. It’s more about plain old poor stewardship. But just to amplify my point above: the shoe box is quite tolerant of poor stewardship.
* * *
Okay, so, this post was not even going to be about the archival problems of families. That is, in aggregate, a large potential loss, made up of hundreds of millions of comparatively smaller losses.
The reason I decided to write today was because I saw this blog post about this article, in which it was described how the on-line archives for a major metropolitan newspaper — going back more than 200 years, are in risk of disappearing from the digital universe.
Here we have a situation in which institutions that are committed to preserving history, with (shrinking) staffs of professional librarians and archivists are failing to preserve history for future generations. In this case, the microfiche archives of the print version of the paper are safe, but the digitally accessible versions are not. The reason: you can’t just put them in a shoe box (or digital library). Someone most host them, and that someone needs to get paid. Forever.
Going forward, more and more of our history is going to happen only in the digital world. Facebook, Twitter, Hillary Clinton’s (or anyone other politician’s) email. There’s not going to be a microfilm version at the local university library. Who is going to store it? Who will access it and how?
A few years ago, it looked like companies like Google were going to — pro bono — solve this problem for us. They were ready, willing, and seemingly able to host all the data and make is available. But now things are getting in the way. Copyright is one. The demand from investors to monetize is another. It used to be thought that you could not monetize yesterday’s paper — today’s paper is tomorrow’s fish-wrap, but more wily content owners realize that if they don’t know the value of an asset, they can’t give it away for free. Even Google, which, I think, hands somewhat tied, is still committed to this sort of project, probably cannot be trusted with the permanent storage of our collective history. Will they be around in 50, 100 years? Will they migrate all their data forever? Will they get bought and sold a dozen times to owners who are not as committed to their original mission to “organize the world’s information and make it universally accessible and useful?” Will the actual owners of the information that Google is trying to index try to monetize it into perpetuity?
I think we know the answers. Right now, it all looks pretty grim to me.
Today’s Wall Street Journal had an article about Facebook, in which they promise to change the way the serve advertising in order to defeat ad blockers. This quote, from an FB spokesperson was choice:
“Facebook is ad-supported. Ads are a part of the Facebook experience; they’re not a tack on”
I’ll admit, I use an ad block a lot of the time. It’s not that I’m anti ads totally, but I am definitely utter trash, garbage, useless ads that suck of compute and network resources, cause the page to load much more slowly, and often enough, include malware and tracking. The problem is most acute on the mobile devices, where bandwidth, CPU power, and pixels are all in short supply, and yet it’s harder to block ads there. In fact, you really can’t do it without rooting your phone or doing all your browsing through a proxy.
The ad-supported Internet is just The Worst. I know, I know, I’ve had plenty of people explain to me that that ship has sailed, but I can still hate our ad-supported present and future.
Today’s ads suck, and they seem to be getting worse. Based on trends in the per ad revenue, it appears that most of the world agrees with this. They are less and less valuable.
Ads create perverse incentives for content creators. Their customer is the advertising client, and the reader is the product. In a pay for service model, you are the customer.
Ads are an attack vector for malware.
Ads use resources on your computer. Sure, the pay the content provider, but the cpu cycles on your computer are stolen.
I’m sure I could come up with 50 sucky things about Internet advertising, but I think it’s overdetermined. What is good about it is that it provides a way for content generators to make money, and so far, nothing else has worked.
The sad situation is that people do not want to pay for the Internet. We shell out $50 or more each month for access to the Internet, but nobody wants to pay for the Internet itself. Why not? The corrosive effect of an ad-driven Internet is so ubiquitous that people cannot even see it anymore. Because we don’t “pay” for anything on the Internet, everything loses its value. Journalism? Gone. Music? I have 30k songs (29.5k about which I do not care one whit) on my iThing.
Here is a prescription for a better Internet:
Paywall every goddam thing
Create non-profit syndicates that exist to attract member websites and collect subscription revenue on their behalf, distributing it according to clicks, or views, or whatever, at minimal cost.
Kneecap all the rentier Internet businesses like Google and Facebook. They’re not very innovative and there is no justification for their outsized profits and “revenue requirements.” There is a solid case for economic regulation of Internet businesses with strong network effects. Do it.
I know this post is haphazard and touches on a bunch of unrelated ideas. If there is one idea I’d like to convey is: let’s get over our addiction to free stuff. It ain’t free.
The other day I was watching Dave Jones, a video blogger that I find entertaining and informative. His blog, the EEVblog, is catnip for nerds who like to solder stuff and use oscilloscopes.
Recently he did a short segment where he answered a question from a student who was upset that his teacher told him that EE was perhaps not a great field for job security, and he sort of went on a colorful rant about how wrong the professor is.
The professor is right.
Electrical engineering employment is indeed in decline, at least in the USA, and I suspect, other development countries. It’s not that EE skills are not helpful, or that understanding electronics, systems, signals, etc, are not useful. They are all useful and will continue to be. But I think more and more of the work, in particular, the high paying work, will migrate to software people who understand the hardware “well enough.” Which is fine. The fact is that EEs make good firmware engineers.
I think someone smart, with a solid EE background and a willingness to adapt throughout your entire career, should always find employment, but over time I suspect it will be less and less directly related to EE.
I mostly know Silicon Valley. Semiconductor employment is way down here. Mostly, it is through attrition, as people retire and move on, but nobody is hiring loads of young engineers to design chips anymore. It makes sense. Though chip volumes continue to grow, margins continue to shrink, and new chip design starts are way down, because “big” SOCs (systems on chip) with lots of peripherals can fill many niches that used to require custom or semi-custom parts.
I suspect that the need for EEs in circuit board design is also in decline. Not because there are fewer circuit boards, but because designing them is getting easier. One driver is the proliferation of very capable semiconductor parts with lots of cool peripherals is also obviating a lot of would-have-been design work. It’s gotten really easy to plop down a uC and hook up a few things over serial links and a few standard interfaces. In essence, a lot of board design work has been slurped into the chips, where one team designs it once rather than every board designer doing it again. There might be more boards being designed than ever, but the effort per board seems to be going down fast, and that’s actually not great for employment. Like you, I take apart a lot of stuff, and I’m blown away lately not by how complex many modern high volume boards are, but how dead simple they are.
The growth of the “maker” movement bears this out. Amateurs, many with little or no electronics knowledge, are designing circuit boards that do useful things, and they work. Are they making mistakes? Sure, they are. The boards are often not pretty, and violate rules and guidelines that any EE would know, but somehow they crank out working stuff anyway.
I do hold out some hope that as Moore’s law sunsets — and it really is sunseting this time — there will be renewed interest in creative EE design, as natural evolution in performance and capacity won’t solve problems “automatically.” That will perhaps mean more novel architectures, use of FPGAs, close HW/SW codesign, etc.
Note that over a 10 year period they are predicting essentially no growth for EE’s at all. None. Compare this to employment overall, in which they predict 7% growth.
One final note. People who love EE tend to think of EEs as the “model EE” — someone clever, curious, and energetic, and who remains so way for 40+ years. But let’s remind ourselves that 1/2 of EEs are below median. If you know the student in question, you can make an informed assessment about that person’s prospects, but when you are answering a generic question about prospects for generic EEs, I think the right picture to have in mind is that of the middling engineer, not a particularly good one.
I’m not saying at all that EE is a bad career, and for all I know the number of people getting EE degrees is going down faster than employment, so that the prospects for an EE graduate are actually quite good, but it is important for students to know the state of affairs.
Technology progresses. Most of the time, progress is good, sometimes bad, but in all times it creates new circumstances, and those circumstances have winners and losers. Our society is not good at recognizing when circumstances have changed. We tend to take, for a long time at least, the world-as-it-is as the world-as-it-ought-to-be.
But I see no reason it must be so. I wish we were better at evaluating our reality, deciding if we like it or want something else, and then, coming to consensus on what, if anything, should be done at a policy level to control our circumstances.
For example, remote control airplanes have been around for quite some time. They were rather expensive toys, and not easy to fly. Similarly, aerial photography has existed almost since the dawn of flight. Because paying a pilot of fly over some location for you and photograph it is not cheap, it tends to be done where value of the resulting photograh is high enough to justify the expense.
For whatever reasons, we were pretty much OK with that status quo and the laws surrounding it. For example, yes, someone could photograph you through your window, and a passing plane could catch you sunning in your yard. People do not like those thigns, but it was hard enough to do and easy enough to stop, that basically, everyone but celebs and paparazzi seemed fine with the world as it was.
Enter inexpensive, simple aerial photograph with UAVs. Today, anybody with a few hundred bucks can get aerial imagery, and in a few years, that might be $10’s or even $1’s. Whole new possibilities for surveillance open up and people are suddenly uncomfortable about their vulnerability.
Does this mean we need laws to stop aerial surveillance “abuse?” Or maybe we need to adjust our expectations of privacy? I dunno. We need to evaluate the situation anew, since technology has changed circumstances. The fact that the existing laws were fine does not mean they are fine.
I can think of lots of contemporary examples of this sort of change: facial recognition along with ubiquitous video cameras make it possible to track everyone, everywhere they show their faces. License plate reader technology allows someone to track everywhere you go. You could do the same before, with detectives or private eyes, but now it can be done in bulk, cheaply. Cookies on websites allow someone to track most of what you look like on the Internet. In essence, people’s expectation of privacy was actually the complex combination of the state of technology and the law together, not either separate from the other.
None of these technologies are sinister in and of themselves, but dropped into a an environment that was in legal equilibrium without them, I think we should expect that equilibrium to shift.
Of course, there are historical examples of such adjustments. Prior to the ubiquity of the automobile, people did not need carriage licenses, nor did they need to carry liability insurance for carriage accidents. How long after cars became popular did we realize they were dangerous enough and important enough that we should require that drivers get training? I think most (though not all) people today regard drivers’ licenses as a good idea. A few decades after that, we started requiring drivers to carry liability insurance and today most states have some requirement, though it is amazingly low in some places. (I know that agreement is hardly universal that liability requirements are a good idea, but we have them.)
One contemporary problem that is not typically considered in this light is gun violence. One might say that extremely capable weapons have been available for a long time, but that they have been expensive enough and just tricky enough to obtain, that we, as a society, were comfortable with the status quo. Collectors and sportspeople had them, and they used them safely, more or less. Enter cheap, easily available weapons, and all of a sudden the game has changed. In fact, today you can 3D print a gun at home, and maybe in a few years you’ll be able to 3D print a most of a not-too-shabby automatic weapon. The technology is not going to go away, but because of the technology change, the status quo is going to shift. Can or should we try to shift it back?
My point is that I think there are many people who advocate for a kind of technological determinism, suggesting, “well, tech marches on.” But history tells us that we clearly do not have to accept such outcomes if we don’t want them.
Freedom-loving readers will notice a whole lot of “we’s” in this essay. I’m afraid they’re right. I’m suggesting that the group sometimes make decisions that restrict an individual’s freedoms. I know there is a cost to that. But I also see costs in letting individuals restrict the freedom (and well-being) of many other individuals.
As always, practicality and balance will be hard to achieve. We all seem fine with driver’s licensure, but pet grooming licenses seem perhaps too far. Required liability coverage for drivers is OK, but we probably would not tolerate such a requirement for many other potentially dangerous-to-others activities.
I hope we will have spirited, informed debates on issues like privacy and autonomy and that the outcome, if not new norms and laws, are new, explicit reiterations of existing norms that were previously implicit.
The patent uses an infrared signal, which could be picked up by the imaging sensor itself. This is rather ingenious and cunning, because you could not disable the shut-down sensor without disabling the camera yourself, since they are one and the same.
Depending one how pervasive such tech became, and how closely integrated the detection, decoding, and disabling is to the actual silicon image sensor, it could become nearly impossible to defeat this tech, or to obtain a phone that doesn’t include it.
I find blocking cameras at concert venues mildly annoying, but the potential for abuse of this technology seems large. Will folks on the street use it to block being photographed? Will it be deployed in government buildinds? Outside cop-cars? Will the secret for how to disable everyone else’s phone get out?
Over the last few years we’ve seen some exciting benefits from ubiquitous deployment of cameras. People are getting caught doing things that are illegal or at least shameful. I’d be bummed to see some technology from Silicon Valley reverse this progress.
Even though my short brush with Internet fame appears to be over (Detrumpify has about 920 users today, up only 30 from yesterday), pride required that I update the extension because it was a bit too quick-n-dirty for my taste. Everything in it was hard-coded and that meant that every update I made to add new sites or insults would require users to approve an update. Hard-coding stuff in your programs is a big no-no, starting from CS 101 on.
So, I have a rewritten version available, and intrepid fans can help me out by testing it. You will not find it by searching on the Chrome Web Store, instead, get it directly from here. It is substantially more complicated under the hood than before, so expect bugs. (Github here, in “v2” folder.)
An important difference between this and the classic version is that there is an options page. It looks like this:
The main thing it lets you do is specify an URL from which a configuration file will periodically be downloaded. The config file contains the actual insults as well as some other parameters. I will host and maintain several configuration files ToolsOfOurTools, but anyone who wants to make one (for example, to mock a different presidential candidate) will be able to do so and just point to it.
If you want to make changes locally, you can also load a file, click on the edit button, make changes, and then click on the lock button. From then on the extension will use your custom changes.
The format of the config file is simple. Here’s an example with most of the names removed:
actions is a container that will hold one or more named sets of search and replace instructions. This file just has one for replacing trump variations, but one can make files that will replace many different things according to different rules
find_regex inside the trump action finds a few variations of Trump, Donald Trump, Donald J. Trump.
monikers section lists the alternatives.
randomize_mode can be
daily , and tells how often the insult changes. In
always , it will change with each appearance in the document.
refresh_age is how long to wait (in milliseconds) before hitting the server for an update.
bracket can be set to a two-element array of text to be placed before and after any trump replacement.
schema is required to ID the format of this file and should look just like that.
whitelist is a list of sites that are enabled to run the extension. Et voila.
Let me know if you experience issues / bugs! The code that runs this is quite a bit more complex than the version you’re running now. In particular, I’m still struggling a bit with certain websites that turn on “content security policies” that get in the way of the config fetch. Sometimes it works, sometimes it doesn’t.
