The argument is basically an example of Gresham's law, which is used to explain why value-backed currency often loses out to fiat currency. IMO this doesn't apply to cryptocurrency because Gresham's law was formulated in contexts with lower liquidity and no electronic transmission.

Thank you for bringing up the 'strings' problem - something I had forgotten about.

It's worth noting, however, that there is nothing inherently dangerous about a strings-like utility. Rather, it is GNU strings which has unexpected complexity:

"Perhaps simply by the virtue of being a part of that bundle, the strings utility tries to leverage the common libbfd infrastructure to detect supported executable formats and "optimize" the process by extracting text only from specific sections of the file. Unfortunately, the underlying library can be hardly described as safe: a quick pass with afl (and probably with any other competent fuzzer) quickly reveals a range of troubling and likely exploitable out-of-bounds crashes due to very limited range checking"

... which is the very issue I'm warning against, just at a different layer of abstraction ...
I believe the point he’s making is that the driver’s attention is more likely to wander when it’s a routine trip done many times before.

This was the first run on the new route, not a routine trip.
The fix is not to take this “dangerous meme” stance.
If the idea is true, then wouldn't it actually be good?

Or, I guess there may be a distinction between "it is good to, for every thing, to be skeptical of that thing" and "for every thing, it is good to be skeptical of that thing".

I consider the statement that "for every statement, it is good to be skeptical of that statement, regardless of what other statements that one is or is not skeptical of" to be doubtful.

It seems fairly clear that skepticism which is directed in a specific way can be harmful?
I don't think point 2 is that we have evidence that rape had occured. Rather, the (intended) claim was that even when a rape occurred, the evidence available would amount to he-said/she-said.

I read "absolutely" in this to exclude cases where the question is not one of facts, but of definitions. Eg. if the victim was somewhat intoxicated, both sides can agree exactly on the facts of what occurred, but disagree if the victims consent was valid.

The mistake is this: the interests of the company and the interests of its management are not always the same thing.

Sure, the company would be better off in the long term with experienced workers producing quality working sustainable 40-hour weeks. But in the short term, Jo(e) Manager can earn his or her bonus by burning some cheap people out with 80-hour weeks, then just getting fresh ones in.

I'm hoping "unified user experience" is meant in a big way -- the promise of a device that can go from touch UI when in my pocket to desktop experience when a keyboard and display are connected is a huge one.

The makings of such support are already there in the hooks iOS has to support different size classes -- currently used to handle device rotation mainly.
If we assume this is all 100% true...there's still no way to be sure during an interview.

There's plenty of shitty older devs. And if they're old enough they're a protected class which will make things very awkward if you hit a shitty one. And with the newer generations, there are plenty of 18 years old that will run circle against more experience devs, nevermind mid 20 ones. There's of course plenty of crappy ones too. So all things equal, but with a different salary, which one do you pick if you're a naive hiring manager?

Fortunately I now work for a company where this is a non-issue. While we definitely hire a ton of new grads, we'll never say no to older/more senior candidates (and sure could use more). Which is good, because I'm getting dangerously close to my 40s.
Accuracy of measuring what? Despite the term, they don't actually detect lies. At best, some of them can detect physiological "events", as when a particular question or word induces acute anxiety. Most interpretation of those events is highly subjective.

The closest thing I've heard of to an objective method, the guilty knowledge test, doesn't center on evaluating the truth of the suspect's statements at all. Basically, the authorities know certain confidential facts about the case, such as the location of a wound, characteristics of a weapon, characteristics of an item stolen by the perpetrator, non-public "calling card" of a serial killer, method used to break into a building, etc.. The interviewer (who should be unaware of the true fact, to prevent something like the Clever Hans effect) is given a list including the true fact and plausible alternatives to incorporate into the questions. The idea is that a reaction specifically to the true fact indicates that the suspect knows something that only the actual perpetrator would know. As far as I know, interpretation of these results is still ultimately subjective because there is simply too much variability in human psychology and physiology to define a useful objective standard of when the test is "failed".
It's because the pace of change leads to uncertainty and a lower demand for "specialists" and a higher demand for adaptability, maleability, and generalization. Thank me later.

> Does that mean if you attempted to write an OS in Go, you'd basically have to do it without many of the features of the runtime (that provide the abstractions that are useful for application progamming?). That would be pretty crummy.

You'd have to write the lowest-level of it in a language that wasn't Go. That language could be C, or Rust, or a pseudo-Go that didn't have many of the features people expect (including garbage collection and goroutines).

"Rape Kits", or rather, the standardization of process for collecting evidence after a sexual assault, are surprisingly good at collecting usable (convictable) evidence after a sexual assault.

The "cyber" stuff pales in comparison to the other reasons.

China’s Ride-Sharing App Didi Raises $4B in New Funding
If people with children in their cars made up a majority of traffic that would be a good argument. Most trips are made solo though. Replacing at least some of those trips with cycling is better for everybody: the cyclists health, the environment, the children playing on the streets.

"BEIJING—China’s ride-sharing platform Didi Chuxing Technology Co. has raised $4 billion in its latest round of funding, according to people familiar with the matter.

Investors of the Beijing-based ride-sharing app, which is expected to list next year, include Japanese tech giant SoftBank Corp. and Mubadala Capital, a Abu Dhabi state fund, these people said. The new money is earmarked for artificial intelligence efforts and international expansion.

Didi carries a valuation of more than $50 billion, making it one of Asia’s largest startups, according to people familiar with the matter. The company also now has $12 billion in cash reserves, including the latest investment, up from $3.5 billion two years ago, these people said.

After purchasing Uber Technologies Inc.’s Chinese operations last year, Didi has been working on pushing its business abroad. In March, Didi opened a research and development lab in Silicon Valley to focus on intelligent driving technologies and AI-based security. The lab now has about 100 staff. The company also is looking to expand to Taiwan with a local partner, LEDI Technology Co.

Some of the money Didi raised will go toward building out an electric car charging network. Didi has said more than 260,000 cars on Didi’s platform are electric and the company aims to increase that number to 1 million by 2020."
Spot on in my experience. Curious if anyone at Google/Facebook/Amazon/Apple core teams could comment on whether these issues are also the case at Google/Facebook/Amazon/Apple? I would imagine solving issues like these do make business sense at big firms with scalability problems.

There are a number of reasons, typical of large projects. Scope creep, mismatched of experience/expertise/organization-setup, unrealistic expectation, insufficient funding, complex vendor/system integration, and long testing cycle.

Funding for PTC inevitably is politically motivated. There are petty projects or requirements tacked onto the main project by various stakeholders, in regardless of technical feasibility.

Railroads are usually operation centric companies focusing on day to day operation. Their expertise is not at designing, engineering, or building things. Outside vendors are brought in to bid on the PTC project. Due to high risk and high liability, only a few companies have the financial backing to put up the surety bond to bid on the project. Sometimes there's only one bidder. The competent ones know the high cost and long time to build the thing and decide to stay put. The less competent one misjudges the time and cost, provides the lowest bid, and becomes the general contractor.

Nobody has a complete set of technologies to implement the entire PTC project. The general contractor has the financial mean but not the technologies. Numerous subcontractors bid on various parts of the project to join the party. The selection of these subcontractors and their technologies sometime are political. The general contractor might not like a sub but is forced to take on the sub because of pressure. A working combination might not be transferable to different railroads due to different vendor/technologies winning the bids.

Pretty much all the vendor technologies are proprietary, and integration among them is a nightmare. Some of them sound good on paper and on promise but fall short when the rubber meets the road. In the failure case I cited above, one fortune 500 company acting as a sub provides a critical part which simply cannot be integrated with the rest of the system. It was too late and too expensive to pick another vendor and the project went into limbo due to running out of funding.

The testing cycle is very long. You are retrofitting a busy daily running railroad live, with people's lives at stake.

> with the conductor being responsible for "enforcing" the safe operation of the train -- i.e. yell at, or even remove the engineer from the controls and/or initiate emergency braking.

Interesting that you mention this. There was a similar fatal train crash in 2003 [1] - remarkably similar circumstances to this one - in which the driver had a heart attack, resulting in excessive speed entering a curve, derailment, and collision with a rock wall.

The organizational culture at the time considered the driver to be the one firmly in charge of the train. Also, the guard/conductor was not in the forward cabin with the driver, but at the rear of the train, a historical anachronism.

After this crash, there was an update to training and procedures that emphasised the guard's responsibility in braking the train if the driver neglected to or was unable to.

That's not statistically valid reasoning. If biking vs driving makes some people not have kids, but not everyone, then in a city where driving is prohibitively expensive you'd still expect most parents to be on a bike. That's because the others didn't switch to cars, they didn't have kids, or they moved. I don't know what riding with one of those bike chariots is like, but being confined to a bike already sucks, I assume dragging a kid around behind you is even worse.

MASc grad (Electrical Eng. - Linear Optimization Applications in Electricity Marktes) who switched over to software after grad school. I'm currently the lead developer helping build the network automation infrastructure for the biggest Canadian Telco. Over the past year or so, I've really enjoyed working with Python on several projects (network automation, full-stack web development etc.) and I'd like to continue working with Python. Having said that, I am pretty flexible and I'm open to considering whatever gets the job done.
This is interesting! The ground truth for the study couldn’t have been far removed from the “ground truth”. I am afraid this appears to me as a pattern where any dataset whatsoever is thrown at ML algorithms and the results are heralded as the new way of analyzing data. There is no regard to the source of the data, it’s deficiencies and utter disregard to its applicability to the problem at hand. See the question generation related deep learning papers based on SQUAD dataset.

This is what I call the Mediocre Mercenary Mentality, this idea that "as long as we can make money off of it, it's good enough".

This mentality is the reason why sometimes -- but not always! -- my phone won't play music in my car until I restart the _car_.

This mentality is why game development companies get away with charging full price for unfinished, bug-ridden games with crippled features and missing content.

This mentality is the reason why I couldn't see my credit card in the list of my accounts on my credit union's online banking site for several days.

This mentality is why Experian and Equifax don't report the same credit score for me.

This mentality is why I feel ashamed every time a receptionist apologizes for the wait, because they "have been having problems with the system."

Most importantly, this mentality is why I have to worry about whether someone will steal my identity because people keep writing shitty code on top of shitty code and my personal information keeps getting leaked.

When I'm so disgusted by my own profession, no wonder I ended up burned out.
I went though the first split, so that $100 is actually equivalent to $200, and that is literally why I chose to sell: I thought to myself ”the market price is now ten times higher than when you purchased, don’t be greedy, take the nine-fold windfall and be content”. It was sound advice to have from one’s own counsel, but... in hindsight I’ve regretted it ever since, it just makes me cringe.
My old local supermarket had a "jukebox" at the entrance, where you could select a song. Every time I went there, I'd put Never Gonna Give You Up on the queue.
