Defenestresque··on France's AMF watchdog fines Bloomberg €5M over Vinci hoax
You mentioned WaPo. Here is an article[0] about WaPo publishing a story about "Russian hackers infiltrating a US electrical grid." In addition to the article being inaccurate, WaPo edited the copy several times to correct major errors of fact without adding an editorial note and refused to explain what led them to their incorrect conclusions.

The article is a bit too long to accurately summarise, but essentially WaPo published a story under the following headline: “Russian hackers penetrated U.S. electricity grid through a utility in Vermont, U.S. officials say.”

>The lead sentence offered “A code associated with the Russian hacking operation dubbed Grizzly Steppe by the Obama administration has been detected within the system of a Vermont utility, according to U.S. officials” and continued “While the Russians did not actively use the code to disrupt operations of the utility, according to officials who spoke on condition of anonymity in order to discuss a security matter, the penetration of the nation’s electrical grid is significant because it represents a potentially serious vulnerability.”

This is at best a deeply misleading intro. The malware was found on a laptop not connected to the grid. The allegation that "Russian hackers penetrated the electrical grid" because they found tools which once may have been developed by Russians is about as accurate as me concluding that a hypothetical murderer was American because the murder weapon was an American-made AR-15.

There are several more concerning parts to the story but alas, I'm on mobile and have slacked off long enough.

I don't buy into the "MSM are knowing purveyors of fake news because profit!" but humans make mistakes and the desire of mainstream newspapers to beat bloggers in timeliness and pageviews can ultimately lead to standards slipping even among writers who would never knowingly publish a false story.

Defenestresque··on AI Clones Your Voice After Listening for 5 Seconds (2018)
People had the exact same concerns when digital image manipulation software became popular, including the "we will never be able to trust an image again" question.

To answer your question, I think the biggest step we took in adapting to the ever-present risk that an image may have been manipulated is acknowledging that it's possible. As soon as people knew that something could be faked, they realized that having a purported photograph wasn't irrefutable proof that it happened and learned to ask for corroboration before making assumptions.

I think we'll learn to deal with this new development too.

Defenestresque··on Apple approves previously rejected HKMap.live app
You are correct that the walled garden contributes to security by creating "another hurdle" for attackers to overcome.

Nobody is arguing that Apple's approach isn't more secure; they are arguing that the tradeoff (an additional layer of security vs. the right to install the software of your choice in a computing device you paid for) is not worth.

There are countless examples of this. Requiring everyone to strip completely naked to get on an airplane would absolutely act as an additional hurdle for a person with nefarious intent, but we don't do that because we acknowledge that there must be a fundamental tradeoff between our safety and our freedoms.

Defenestresque··on Border agents are checking social media, but we still don’t know how closely
Here's the thing, I know exactly what rules I'd ordinarily need to follow in order to enter the United States. It's a mental checklist when coming from Canada:

1) am I carrying any contraband? Drugs, guns, undeclared currency or goods, etc.

2) Can I show that I can support myself during my stay? Do I have a return ticket? Enough cash?

Compared to these requirements these searches are completely opaque. If I'm asked to hand over my device I'm thinking:

1) How much is the agent going to access? Is s/he going to see an NSFW pic I emailed to the gf?

2) Are there any legitimate protections keeping them from logging into my social media accounts and going through my history?

3) Is there any recourse if they see me making a "420" joke ten years ago on Facebook and denying me entry?

There should be clear criteria admissibility that also serves to protect your privacy.

Defenestresque··on Long Ago, a Pilot Landed on an Uptown Street (2013)
Reminds me of Mathias Rust, when at the age of 18 and with 50 hours of flying experience he flew a Cessna from an airport in Helsinki and landed it in Moscow's Red Square at the height of the cold war.

He wanted to reduce tension and build a bridge between the west and the east, but mostly succeeded in embarrassing the hell out of the Soviets -- the air defense system tracked him multiple times throughout his flight and even scrambled interceptors twice to locate him, ultimately taking no action both times.

The first fighter pilot misidentified him as a Soviet plane, and the second presumably made a report identifying him as a foreign Cessna but was either not believed or the information was not followed up on.

Soviet radar continued to track him throughout, at one point their systems noticed that Mathias failed to change his transponder code on schedule to identify himself as friendly and flagged him as "hostile". A commander manually overrode that identification, flagging him as "friendly" because he didn't want to shoot down what he presumed was a forgetful Soviet student pilot.

He continued on, with the Soviets assuming he was a student pilot, or a training flight, or an airplane on an SAR operation.

The Soviets only realized something was horribly wrong when the little Cessna cleared all of the anti-missile defenses and made for a landing in the Red Square. His reception was festive:

>He got out of the Cessna. Expecting to be stormed by hordes of troops and KGB agents, Rust leaned against the aircraft and waited. The people in Red Square seemed nervous or stunned, not sure what was going on. Some thought Rust’s airplane might be Gorbachev’s private aircraft, or that it was all part of a movie production. But once the crowd realized that Rust and the Cessna were foreign—and that he’d just pulled off one of the most sensational exploits they had ever witnessed—they drew closer.

>“A big crowd had formed around me,” Rust says. “People were smiling and coming up to shake my hand or ask for autographs. There was a young Russian guy who spoke English. He asked me where I came from. I told him I came from the West and wanted to talk to Gorbachev to deliver this peace message that would [help Gorbachev] convince everybody in the West that he had a new approach.”

He did succeed in helping Gorbachev, however. The double-whammy of Mathias' actions and the Chernobyl disaster proved to him that the Soviet system was ineffective and inflexible and convinced him to implement reforms.

>One German periodical published a story saying Rust did the stunt on a bet. Another reported that he did it to impress a girl. Yet another said he did it in order to drop leaflets seeking to free nonagenarian Rudolf Hess, Hitler’s lieutenant, from jail. The Communist newspaper Pravda accused Rust of being a patsy in an international plot in which he was supposed to have been shot down and killed in order to provoke an international incident. However ridiculous the rumors were, the Soviets methodically looked into every allegation.

>On June 23, 1987, the Soviets completed their investigation. Shortly afterward, prosecutors charged Rust with illegal entry, violation of flight laws, and “malicious hooliganism.” Rust pleaded guilty to all but the last charge. There was, he argued, nothing malicious in his intentions.

As Mathias said,

>“I thought my chances of actually getting to Moscow were about 50-50, [...] but I was convinced I was doing the right thing—I just had to dare to do it.”

Defenestresque··on Uber’s Operating and Marketing Chiefs Step Down in Leadership Shakeup
I was curious about the stark discrepancy between your numbers and the parent's, so I did some quick research.

I think you're both kind of right. Reuters writes:

>In 2015, Uber passengers were paying only 41 percent of the actual cost of their trips, according to an analysis by transportation industry consultant Hubert Horan, based on financial statements from Uber. [0]

Of course that's four years ago. What about 2018 numbers? An interesting article makes some allegations about Uber deliberately inflating their profits [1] and making it difficult to tease apart the details:

>When Uber abandoned its failed Chinese, Russian and Southeast Asian operations, the dominant local companies gave Uber equity and debt instruments to partially compensate it for providing them an easier path to market dominance. These non-tradeable instruments only exist because of Uber’s decision to discontinue operations, but Uber includes their $5 billion value in “Net Income From Continuing Operations”

>The current accounting value of these assets is based entirely on Uber’s judgement as to what paper issued by companies currently losing massive amounts of money might be worth someday. [5] If one takes Uber’s judgements at face value, one could conclude that Uber’s only profitable activity is getting paid off for discontinuing staggering unprofitable markets.

..as well as..

>Lyft’s IPO prospectus presented ridesharing unit revenue data but Uber did not. Uber only presented the sum of car service and food delivery trips, so prospectus readers couldn’t figure out what customers were paying for the two services separately, or how prices for the two services have changed. The combined data suggest that both growth rates and pricing was declining in the second half of 2018, but prospectus readers have no way to identify the underlying problems, or whether those problem are likely to get worse.

Defenestresque··on Hackers can fake radio signals to 'hijack' aircraft landing systems
There are a couple of very interesting articles on GPS spoofing. Not only is it doable [0] but there are some interesting cases that most people don't really think about. Consider that GPS is often used as a timing signal by various financial entities (including stock exchanges). If you override the legitimate GPS signal (not a lot of power required as you'll be much closer to the receiver) and introduce a small deviation into the timing signal you can create some very interesting (and profitable) effects in the stock market. [1]

Even introducing an error into the system can cause disastrous effects [2]

Defenestresque··on Bank of America is raising its minimum wage for employees to $20
>Raising minimum wage will definitely force low end wages up but my worry is will it also raise prices by the same percentage (within some small timeframe) such that the employees buying power remains the same.

Fortunately the recent increases in minimum wages in several US locales means that there is quite a lot of data available for studies that assess the impact of minimum wage increases on prices.

For example, from "The Effects of Increasing the Minimum Wage on Prices: Analyzing the Incidence of Policy Design and Context (2016)" [0]

>By looking at changes in restaurant food pricing during the period of 1978–2015, MacDonald and Nilsson find that prices rose by just 0.36 percent for every 10 percent increase in the minimum wage, which is only about half the size reported in previous studies. They also observe that small minimum wage increases do not lead to higher prices and may actually reduce prices.

The interestingly-named page "$15 Minimum Wages Will Substantially Raise Prices" [1] from the Heritage Foundation cites multiple studies showing that a 10 increase in minimum wage will increase prices between 0.2% and 1.8% with most estimates around 1%. (Perhaps their definition of substantial is different from mine?)

>Sarah Lemos of the University of Leicester surveyed roughly 30 studies conducted before 2005 examining minimum-wage price effects. These studies found that minimum-wage increases have relatively small effects on the overall price level. They reported that a 10 percent minimum-wage increase raises overall prices by about 0.2 percent to 0.3 percent.

>Researchers at the Federal Reserve Bank of Chicago and the Department of Agriculture, published a study in 2008 examining how restaurants respond to minimum-wage increases. They used Consumer Price Index (CPI) data and examined the 1996–1997 federal minimum-wage increase. They found that a 10 percent increase in the minimum wage raises overall restaurant prices approximately 0.7 percent. Unsurprisingly, they found larger effects in restaurants that employ more minimum-wage workers. Prices increased twice as much—by approximately 1.5 percent—at fast-food restaurants. In lower-wage regions, fast-food prices rose 1.8 percent.

>In 2010, Denis Fougère, Erwan Gautier, and Hervé Le Bihan, researchers at the Bank of France, criticized the econometric model that Aaronson and his co-authors used. [...] They concluded that a 10 percent minimum-wage increase raises restaurant prices by approximately 1 percent, although it takes one to three years for price increases to fully materialize

>This survey records the price of a McDonald’s quarter-pounder, a regular Pizza Hut cheese pizza, and Kentucky Fried Chicken fried drumsticks across America. They found that a 10 percent increase in required starting wages raises the price of burgers and pizza by about 1 percent. Curiously they found little effect on KFC chicken prices.

Defenestresque··on Komodo Island Is Closing to Tourists Because People Are Stealing Dragons
>just a scratch from a bite from a Komodo can be deadly

That's incorrect.

>In 1969, Walter Auffenberg came along and made his detailed study of Komodo dragon behaviour. He made two critical observations:

>1) Komodo dragons can kill large prey, occasionally even buffalo, outright.

>2) buffalo that escape a Komodo dragon attack often die of infection.

>Auffenberg, based on the second observation, hypothesized that the dragon had septic saliva and used it to kill large prey slowly over days or weeks, even though his own published field observations contradicted this. The public caught wind of this idea, and the myth of the Komodo dragon as a slow killer with a virulent bacterial brew was born.

>Then, in the 21st century, Dr. Bryan Fry discovered the presence of modified salivary glands in the dragon's lower jaw. The compound produced by these glands proved to be a potent anticoagulant.

>Dr. Fry believed that this substance was venom, since many types of snake venom also cause uncontrollable bleeding. He also recognized that Komodo dragons kill prey quickly rather than over a long time, since he actually observed these animals hunting. Unfortunately, the press totally missed that last bit, so the myth lived on in modified form, with venom replacing bacteria.

>The original venom hypothesis has come under fire recently (Hargreaves et al, 2015), and many scientists now believe the anticoagulant is a digestive enzyme. There are many reasons to indicate that venom doesn't play a role when killing prey, which certainly fits with the observations of Komodo dragons killing prey violently and swiftly.

>In 2013, another study revealed that there was no septic bacteria in the Komodo dragon's maw. In fact, it has a cleaner mouth than most mammals due to constantly replacing its teeth, leaving no chance for trapped food to rot and fester before they fall out along with the dentition.

>It is a fact that Komodo dragons do not wait for prey to die, even though this myth is still being presented as true by pop culture. What really happens in these cases is something else entirely: prey escapes, gets infected, dies, and is eaten by a dragon (possibly the same one if it happens to be nearby). There is never any intent by the dragon to kill its prey in this way. They try to kill quickly, in some cases even near-instantaneously, and usually in just a few minutes.

As a bit of an aside, I posted a comment [0] on Reddit when this was posted yesterday. It links to a gallery with a lot of interesting info about Komodo dragons. Like me, you probably have at least a few false beliefs about Komodo dragons (such as the fact that they are slow scavengers, or that they are venomous or use bacteria to poison animals before waiting for them to die).

Anyone curious should check out this amazing gallery of pics/videos and captions that really blew my mind and totally changed my perception of this fearsome lizard!

Defenestresque··on How to lose $172k per second for 45 minutes (2013)
There is a really, really interesting breakdown of this document on kitchensoap.com [0]

The writer breaks down why this document is not a post-mortem despite superficial similarities.

>Again, the purpose of the doc is to point out where Knight violated rules. It is not: 1) a description of the multiple trade-offs that engineering at Knight made or considered when designing fault-tolerance in their systems, or 2) how Knight as an organization evolved over time to focus on evolving some procedures and not others, or 3) how engineers anticipated in preparation for deploying support for the new RLP effort on Aug 1, 2012.

>To equate any of those things with violation of a rule is a cognitive leap that we should stay very far away from.

>It’s worth mentioning here that the document only focuses on failures, and makes no mention of successes. How Knight succeeded during diagnosis and response is unknown to us, so a rich source of data isn’t available. Because of this, we cannot pretend the document to give explanation.

He also makes an interesting point related to what you're saying: the SEC says the risk management controls were inappropriate, but clearly Knight thought they were appropriate or they would have fixed it.

>What is deemed “appropriate”, it would seem, is dependent on the outcome. Had an accident? It was not appropriate control. Didn’t have an accident? It must be appropriate control. This would mean that Knight Capital did have appropriate controls the day before the accident. Outcome bias reigns supreme here.

I'd go into it more but I would instead recommend you take a look at his breakdown as I'd be trying to do a shoddy summary of a really interesting write-up.

Defenestresque··on Can you buy your own train?
I see a sleeper cabin for two listed for $1558 (discounted from $2428 reg price) and there are often even steeper discounts available. [0]

You can get an "upper berth" sleeping ticket with meals for $968.50. Considering that's a 4-day sightseeing trip compared to a 4-5hr flight I don't think a $300 premium is outrageous, do you?

In fact, the cheapest business class ticket one-way I can find is $871. That makes the difference less than $100!

(In fact I am amazed that the prices are in fact comparable between a 4-day train trip and a 5-hr flight. Definitely something I didn't expect.)

Clearly you had a bad experience, but considering that Amtrak obviously kept an eye on the issue, determined a fix and resolved it to make sure it doesn't happen again -- wouldn't that make you more likely to take Amtrak in the future? Not all companies are as pro-active about fixing problems.

Just not sure why their brand would be ruined considering the one issue you had with the service was proactively resolved.

Defenestresque··on AT&T 1993 “You Will” Ads [video]
A few months ago I ordered a book on a whim called "The Idea Factory: Bell Labs and the Great Age of American Innovation." [0]

I was surprised by how much I enjoyed it and how much I learned. There were amazing minds at Bell Labs who were given free reign to innovate (as a direct result of AT&T's huge monopoly and revenue stream) and ended up laying the groundwork for many ideas and concepts we take for granted today.

The book is so dense with information and anecdotes but I'd still consider it a page-turner. I highly recommend it.

Defenestresque··on How Japanese Police Turned Cyber Prank into Arresting Cases
The point the articles continues to make is actually the opposite of what you're implying, the very next sentence says:

Consequently, the court (and the public) take the view that mere confession of guilt alone is never any sufficient ground for conviction.

Instead, for confession to be a valid evidence for conviction, the Japanese court requires confession to include revelation of verifiable factual matter which only the perpetrator of the crime could have known such as the location of an undiscovered body or the time and place the murder weapon was purchased, a fact about the crime scene, etc. Furthermore, to safeguard against the possibility that the interrogator implanting such knowledge into confession, the prosecutor must prove that such revelation of secret was unknown to the police until the point of confession.

I find this fascinating. Specifically, this part:

While it is impossible for an innocent suspect to reveal relevant information about a crime even under severe torture, a guilty suspect is likely to crack under prolonged interrogation in isolation and make a damning confession. Activists claim that the Japanese justice system (and Japanese public to some extent) consider that prolonged interrogation of suspect in isolation without access to lawyers is justified to solve the criminal cases without risking the miscarriage of justice.

This is so completely unlike any western approach to justice that is familiar to me that I cannot pass any judgment on it without knowing its efficacy relative to percentage of false confessions.

The argument of this technique's validity is somewhat undermined in the next paragraph where the authors notes that false confessions still happen, so I'll definitely give you that!

As an aside, as someone upthread alluded to, this is a fascinating example of an article that breaks almost all of the Wikipedia editing rules but is surprisingly informative.. probably more informative than it would have been if it omitted the synthesis and OR

Defenestresque··on Medical Mystery Grows as U.S. Consulate Workers in China Fall Ill
While we don't have a lot of information about the China incidents yet, I found this journal article about the Havana attacks interesting:

>Results Of 24 individuals with suspected exposure identified by the US Department of State, 21 completed multidisciplinary evaluation an average of 203 days after exposure. Persistent symptoms (>3 months after exposure) were reported by these individuals including cognitive (n = 17, 81%), balance (n = 15, 71%), visual (n = 18, 86%), and auditory (n = 15, 68%) dysfunction, sleep impairment (n = 18, 86%), and headaches (n = 16, 76%). Objective findings included cognitive (n = 16, 76%), vestibular (n = 17, 81%), and oculomotor (n = 15, 71%) abnormalities. Moderate to severe sensorineural hearing loss was identified in 3 individuals. Pharmacologic intervention was required for persistent sleep dysfunction (n = 15, 71%) and headache (n = 12, 57%). Fourteen individuals (67%) were held from work at the time of multidisciplinary evaluation. Of those, 7 began graduated return to work with restrictions in place, home exercise programs, and higher-level work-focused cognitive rehabilitation.

>Conclusions and Relevance In this preliminary report of a retrospective case series, persistent cognitive, vestibular, and oculomotor dysfunction, as well as sleep impairment and headaches, were observed among US government personnel in Havana, Cuba, associated with reports of directional audible and/or sensory phenomena of unclear origin. These individuals appeared to have sustained injury to widespread brain networks without an associated history of head trauma.
