Bluetooth Audio on Planes is Real and it’s Spectacular

ssegraves

I recently flew on a couple of United’s newer planes in the domestic fleet, a 737 MAX 8 and a MAX 9. The MAX 8, tail number N27267, was delivered to United in August and it still had that new plane smell. It also had United’s new inflight entertainment system, including Bluetooth audio for passengers to use to listen to the movies or television that were watching on their screen. I decided to give it a shot and was pleasantly surprised at how well it worked.

Bluetooth Audio Setup

You simply flip the switch for Bluetooth audio and put your device in pairing mode. A few seconds later it is connected and you’re listening wirelessly. For me, the biggest annoyance was that with my Apple Airpods Pro 2 had to be manually set to pair by holding the rear button, essentially wiping out the pairing information with my phone. I am not sure if this is my error or a flaw in how the Airpods pair but it was a small inconvenience.

The audio quality while enjoyable was not high quality. It actually didn’t sound any better than simply plugging wired headphones in. There was a slight static in the background and for scenes with music, it was definitely missing some bass. Part of me thinks this is a result of how the content on these systems is stored, likely highly compressed to save space. It could also be simply an interference issue. With Bluetooth being at every seat, that’s a lot of potential radio interference very close to you. Again, this wasn’t a huge downside for me. Being able to use hardware I already use everyday means I can carry less and it just worked. I’m really glad I got the chance to try it out!

One interesting quirk is that they can’t pipe PA announcements over Bluetooth and specifically ask you to remove the headphones when an announcement comes on.

Have you had a chance to try Bluetooth on United or another carrier? What was your experience like?

Two Classes of Travelers

Fascinating write-up about the TSA, PreCheck, and CLEAR by Nilay Patel for The Verge:

This year is the 20th anniversary of the Department of Homeland Security and the TSA, and I think it’s safe to say that nobody enjoys waiting in the airport security line. And in the post-9/11 world, things like PreCheck are the great innovation of the department.

At least according to Dan McCoy, who is the TSA’s chief innovation officer, who told me that PreCheck is “a hallmark government innovation program.”

And the thought that I think sits in the back of the mind for most travelers:

But what do programs like PreCheck and the larger surveillance apparatus that theoretically keep us safe mean for the choices we make? What do we give up to get into the shorter security line, and how comfortable should we be about that?

In response to a question about security versus privacy:

This is definitely a hard one to answer from my part. From the innovation perspective, there is intelligence and analysis in the backend that is doing a lot of this work. We have partnerships with the FBI for those background investigations that you are talking about. If you ask an end user to design the best app, they want it to look slick and be frictionless as far as mobility and application development. That is only until you probe them with, “Well, do you want your data to be secure? Do you want to know that you are not being tracked?” I think that is what I equate the TSA process to. Most of my life, TSA has been the way that we go through the airport.

The interview continues on to talk about face recognition and how CLEAR keeps a database of faces but the TSA has taken a different approach, which is Real ID and the verification of a face matching the ID. If you read the full transcript, which is embedded in the above linked article, McCoy mentions that the TSA understands machine recognition of facial data is getting better but it is not at a point where they feel comfortable rolling it out en masse.

Dan McCoy does dance around a few questions, in particular the one around there being only a single attempt to bring a plane down with a shoe bomb but non-PreCheck travelers still have to take their shoes off at security. He gives some pure marketing speak in response to the question and doesn’t give a solid reply as to why the shoe rule is still in place.

My feelings on PreCheck and the rest of the traveling public is that we really should be working to move travel to PreCheck for the majority of passengers and extra security when needed. This is especially true now that travel has picked back up while security remains relatively understaffed. Unfortunately I feel that we’ve crossed an invisible line in the sand and security will never go back to anything like it was pre-9/11. The TSA should really be looking at a future where they can vet passengers quickly and correctly while at the same time insuring that the entire experience isn’t a mess.

The Montreal Snow Removal Army

ssegraves

I spent a few months traveling to Montreal for work right before Covid hit, right in the middle of winter. I noticed that the sidewalks and streets stayed mostly clear of snow and now I know why. This fascinating article on the snow removal process in Montreal makes every other city’s efforts pale in comparison.

In Montreal, a blizzard is a call to action. With a budget of nearly $180 million and a staff of over 3,000 workers, the city is poised and prepared to manage and remove it all. Once snow begins accumulating, a multiphase operation begins to unfold across the city’s 19 boroughs. Between roads, bike lanes, and sidewalks, the city clears over 10,000 km – roughly the distance between Montreal and Beijing.

Montreal doesn’t just push snow to the curb with plows – instead, snow is picked up by a fleet of trucks and transported up to one of 28 snow dump sites across the city. Throughout a typical winter, roughly 300,000 truckloads of snow are transported – a volume of about 12 million cubic meters.

Part of the snow removal process is available to view:

The whole article is a fun read. Montreal has massive snow mountains where snow is trucked to melt later and they use the old Francon quarry as a storage area as well –

The final site we visited was the crown jewel of Montreal’s snow storage strategy: the Francon quarry. In decades past, it provided the limestone that built Montreal’s posh downtown districts. And since its retirement, it has become the city’s largest snow dump.

This doesn’t mean Montreal’s snow removal is perfect though. On two of my trips to the city there was a large storm the day before I arrived and sidewalks were an absolute mess.

Ford F-150 Lightning – An Ultimate Truck?

ssegraves

I have been on the fence on the Tesla electric vehicles for a while and for a few reasons. For one, it seems ironically wasteful to buy a new vehicle simply because “it’s electric” and has a bunch of bells and whistles. The price point tiers of the Tesla are also a downside. Yes, you can get a base Model 3 for $33k but to get any kind of upgrades it’s $42k and if you want more performance, it’s $50k. All for a sedan.

Enter the Ford F-150 Lightning. I am still hesitant to buy an electric vehicle right now but the F-150 is more my speed. Ford has taken their best selling vehicle and made it an electric powerhouse. This feature preview by Marques Brownlee points out some of the coolest things with picture and video better than I ever could.

An EPA estimated range with 1000lbs of cargo of 300 miles but in reality closer to 450 miles (based on Marques’ math). Also, dual direction power where if your house loses power, you can use the truck to provide power to it. That’s huge. It’s a 6000lb truck but can still do 0-60mph in 4.5 seconds. I mean, that’s not something you’re going to use everyday but it is impressive.

It seems like a vehicle to keep an eye on. I have a feeling Ford is going to sell a lot of these and it might play a huge role in more electric vehicle charging stations and other tech entering the market.

Hacking McDonald’s Ice Cream Machines

Andy Greenberg from Wired (archived, non-paywall version):

Of all the mysteries and injustices of the McDonald’s ice cream machine, the one that Jeremy O’Sullivan insists you understand first is its secret passcode.

But after years of studying this complex machine and its many ways of failing, O’Sullivan remains most outraged at this notion: That the food-equipment giant Taylor sells the McFlurry-squirting devices to McDonald’s restaurant owners for about $18,000 each, and yet it keeps the machines’ inner workings secret from them. What’s more, Taylor maintains a network of approved distributors that charge franchisees thousands of dollars a year for pricey maintenance contracts, with technicians on call to come and tap that secret passcode into the devices sitting on their counters.

This is a fantastic look inside the world of fast food, the kitchen tools that make the industry run, franchise and franchisee relationships, and the right to repair movement as a whole. I wonder what the outcome would have been had the protagonists had cozied up with the ice cream machine manufacturer.

Threats to Critical Infrastructure

ssegraves

From War on the Rocks:

Circumstantial evidence suggests that Warner was protesting 5G technology — reportedly an FBI line of inquiry. The campervan was parked in front of an AT&T transmission building and the explosion knocked down a network hub. The company website called the blast “devastating,” reporting secondary fires, loss of power, damaged equipment, and hazardous work in a disaster zone. Internet and cellphone service across parts of Tennessee, Kentucky, and Alabama was badly affected. AT&T scrambled to reroute service or deploy portable cell sites, with 65 percent of service restored two days later.

Experts saw this coming. In May 2020, the U.S. Department of Homeland Security issued alerts about potential attacks on cellphone infrastructure due to conspiracy theories about 5G technology spreading COVID-19 — misinformation promoted by gullible individuals, celebrities, and nefarious actors like QAnon. U.S. alerts followed dozens of arson and vandalism attacks abroad, including on U.K., Belgian, Canadian, and Dutch cell towers. And in the wake of the Nashville bombing, federal, state, and local law enforcement feared copycat attacks on other U.S. communications infrastructure.

There have always been conspiracy theories but it seems that the prevalence of social media in people’s daily lives has helped perpetuate untruths even faster than in the past. When I talk to friends and family and their main source of news is Instagram, Facebook, or some obscure website, I usually expect to see or hear a conspiracy theory at some point.

Facebook’s Scale

ssegraves

Adrienne LaFrance, writing for The Atlantic, “Facebook Is a Doomsday Machine”:

People tend to complain about Facebook as if something recently curdled. There’s a notion that the social web was once useful, or at least that it could have been good, if only we had pulled a few levers: some moderation and fact-checking here, a bit of regulation there, perhaps a federal antitrust lawsuit. But that’s far too sunny and shortsighted a view. Today’s social networks, Facebook chief among them, were built to encourage the things that make them so harmful. It is in their very architecture.

I’ve been thinking for years about what it would take to make the social web magical in all the right ways — less extreme, less toxic, more true — and I realized only recently that I’ve been thinking far too narrowly about the problem. I’ve long wanted Mark Zuckerberg to admit that Facebook is a media company, to take responsibility for the informational environment he created in the same way that the editor of a magazine would. (I pressed him on this once and he laughed.) In recent years, as Facebook’s mistakes have compounded and its reputation has tanked, it has become clear that negligence is only part of the problem. No one, not even Mark Zuckerberg, can control the product he made. I’ve come to realize that Facebook is not a media company. It’s a Doomsday Machine.

I disagree with the idea that Zuckerberg can’t control his creation. Facebook can be reined in, if Zuckerberg wanted it controlled.

Mystery Colorado Drones

ssegraves

Late in 2019 there were a number of reports around mystery drones flying over northeastern Colorado and western Nebraska. The origin of the drones remained a mystery for quite a while (and still does), but a bunch of research has given some insight into the concern around unidentified drones flying around the country.

Nevertheless, the documents already released suggest that the FAA, despite a short-lived, but strenuous effort, was unable to determine the origin of the flying formations of sizable aerial devices reported by many credible witnesses in December and January. Senior FAA officials were able, however, to conclude that “there is high confidence these are not covert military activities.”

The released documents contain no evidence that any federal criminal laws were broken by whoever was operating the devices, although the FAA has withheld at least one key document discussing the legal issues surrounding the case. No document yet released suggests that the mystery drones ever encroached on any U.S. military installation, or even into any airspace that was under special FAA restrictions.

So, although The War Zone and the SCU have pursued the Colorado drone flap for over half a year, we still don’t know who was behind the mysterious activity, and from what we’ve seen so far, no one in the Federal Aviation Administration knows either. It’s clear from these FOIA releases that the FAA, state and local authorities in Colorado, and even the AFOSI, took the sightings quite seriously, but it appears that their attention quickly shifted elsewhere once the public reports stopped.

It seems like whoever was behind the drone flyovers learned that there was a large investigation going on and soon stopped their shenanigans, but it still makes for a fascinating mystery. Based on the “space potatoes” that were found, I am wondering if it was some kind of crop health experiment or a agriculture company doing some kind of research. Again, we’ll likely never know unless the owners of the drones come forward.

25 Years of PHP

ssegraves

I know, I’m a day late… On June 8, 1995 Rasmus Lerdorf announced “Personal Home Page Tools (PHP Tools)” on a CGI usenet board (now converted to a Google Group). PHP quickly became a great way to make dynamic websites and it is still going strong today. I started using PHP in 2001 and I still turn to it for projects, including this website. Sure it has its quirks and bugs but it has been an evolving language that to this day has a loyal following.

New programming languages have been created and I am sure a lot of people have moved on to them (Node, Go, Rust, etc.) but PHP still drives a large chunk of the internet, something like 80 million websites. I have met a lot of friends because of the language including Chrispian, Patrick, Brad, Brandon, and many others at WordCamp events, or programming meetups. I am really thankful for those friendships.

Anyway, I’m happy for Rasmus Lerdorf and for the language.

Airpods Pro – A Few Months In

ssegraves

I wrote a post in late November about the perfect travel earbuds that focused on my search for earbuds that would fit my needs. After that, I started seriously looking at the AirPods Pro. At first, I really balked at the idea of the AirPods; I thought the stems sticking out of the ears looked really ridiculous and that it was a frivolous purchase. However, a co-worker had recommended them and after some research, I picked up a pair. After having them for a few months, I have to say that I’m impressed. I mostly use the AirPods Pro for listening to music while commuting on the train, or to iPad video when on a plane, or occasionally for phone calls.

Audio Consumption

At the time that I bought the AirPods Pro I was traveling to New York City every week, a 5-6 hour flight, depending on winds. I spend my time on planes typically working while listening to music or with a television show on my iPad that I can kind of ignore (I like the noise). The AirPods Pro offer great noise cancellation that reduces the engine noise to a dull hum. It performs less efficiently when it comes to human noise, talking, crying, etc. when on the plane. I don’t know if this is because the headphones are working so hard to reduce the engine noise or if they just struggle with noncontinuous noise.

The audio quality for video is perfect for me, the noise cancellation makes it so I don’t have to have my iPad turned all the way up and the clarity is good enough that I didn’t notice any issues. For music, I am no audiophile but I was happy. The bass is enough for me without being so heavy I can’t enjoy a song. All in all, I am happy to listen to music on the AirPods Pro. When walking around town I typically use transparency mode just to be aware of my surroundings. In NYC this is a huge help to hear sirens or people honking when at crosswalks, etc. As soon as I would get to the subway, I turn on the full noise cancellation and don’t have to hear the screeching of a train coming into the station or other loud noises.

The two big things that I appreciate with the AirPods Pro is that they are comfortable to wear and the single charge life of the earbuds is as advertised, 4.5 hours. I could almost make it from takeoff to landing on a single charge with the AirPods Pro. I typically charged them around halfway through the flight just to make sure I could make a call if needed after landing. My skepticism on the comfort of the earbuds was very strong from the get go, but they proved me wrong. I have no issue leaving AirPods Pro in my ear for significant stretches of time. It took a little bit of trial and error to choose the correctly sized plastic ear insert but once I tested them all, I was able to pick the ones that were best for my comfort.

Calls – Observations

The AirPods Pro have been an up and down experience when it comes to phone calls. Typically I can hear calls just fine but my audio back to the call is frequently broken. I have not been able to pinpoint out why this is but it seems like the Bluetooth connection is a little more flimsy. Having the noise cancellation feature is great for calls because you can be walking down a busy street and hear a call perfectly.

Other Tidbits

I know that a lot of travelers love over the ear noise cancelling headphones but for me, they take up too much space in my bag for only being useful on the plane or in a place where I’m not moving around too much. The only upside of those over the ear headphones or even wired earbuds is being able to plug-in to inflight entertainment on the plane. With the AirPods Pro there is no way to connect to inflight entertainment. Because of this, I carry a wired pair of headphones as well which definitely not what I would like to do.

The other area where I am a little disappointed with the AirPods Pro is keeping them clean. The rubber earpieces seem to be ear wax magnets and they have a piece of mesh that makes them difficult to clean. It takes a bit of finesse to get any kind of cleaning element deep enough into the earpiece to get them clear which is annoying. There also seems to be a tendency of dirt and dust to get into the bottom of the charger which can potentially keep the AirPods Pro from charging when they are in their case. I wish it was easier to keep these elements clean but it’s a small complaint.

Summary

The AirPods Pro fit my needs of a walking around, on the plane, noise cancelling earbud perfectly. The battery life of 4.5 hours without a charge is great and the comfort level of the earbuds themselves allows me to leave them in for extended periods of time. The noise cancellation and transparency mode are really fantastic features that make going from noisy environments to areas where you need more awareness easy and responsive. My only real complaints are that the AirPods Pro are a little difficult to clean and grit/grime can keep them from charging. The phone calls can be hit or miss when it comes to audio but it’s usable for casual conversations. If you are traveling a lot or need some earbuds to walk around town, these are a great option and one that you should seriously consider even if you’ve had doubts about AirPods before.
