It's easy to see why compiler developers added these optimizations: someone filed a bug saying "hey, why is my loop full of movsx", and the developers fixed the problem.

"fixed" by breaking other expectations. Regardless of what the spec says, that's still a stupid way to do things. There's a child comment below which examines this case in detail; and the real solution is to make the analysis better, not use UB as a catch-all excuse.
> I believe valve has no clue what their audience wants.

Maybe that's the problem - if they were trying to make something they think the audience wants. The audience itself doesn't know what it wants, let alone anyone removed from it making guesses on their behalf.

The audience didn't know they wanted DotA or Minecraft until they were made.
Brand is certainly a dimension in some cases (see: Apple products) but it's inconsistent per consumer.

Reminds me of that story about Archimedes.

For anyone unfamiliar: supposedly, while bathing; he suddenly realized the principals of buoyancy. He then jumped out of the bath and ran down the street -- without clothes -- yelling "Eureka!"

NullAway: Fast Annotation-Based Null Checking for Java
I'm not sure I'm parsing this question correctly, but it sounds like a contracts question, and I'm not at all privy to the contract between any airline and Boeing, whether they have any contingency for this.

The actual risk is complex, an airline with more capacity depending on the new model has more risk as they take on new planes and retire old ones, but does the contract reflect that complexity? I have no idea. For all I know, there's generic terms for handling all certification problems that crop up, including airworthiness directives from the FAA that affect A&P's rather than pilots. It might be the two sides split the cost 50/50 for all I know, or maybe they use binding arbitration to keep the airing of dirty laundry as much out of the public view as possible.

Anyway, you don’t need to opt out of religion, that’s the default state. To use an obvious example, at birth people don’t have a codified view of what happens after death.

People can and often are biased based on their upbringing, but that in effect takes effort from an existing believer to communicate their beliefs directly or via artifacts like books. Without that, nothing forces you to form an option.
Isn’t that how most of us are solving complex problems? Building context and then walking away from the desk for a walk, or perhaps while we’re in the shower in the morning or at night, not focused on the problem but our brain working on it in the background until it is brought forward to our consciousness?
A single layer perceptron IS linear regression + some non-linearity of the output. I think in reality they could have used the word "logistic regression" but chose perceptron because it sounds better.

That benchmark only has a few samples on an unreleased cpu. Typical ballpark numbers for memory latency are usually 100ns. There are also a lot of factors that can influence random memory access such as whether the lookup is going through virtual memory that isn't a page in the TLB cache. I'm skeptical this benchmark tells us much.

Also games that are sensitive to memory latency are very poorly written games. This is not a new or contraversial opinion of PubG, which is know for being terribly written (and that is supposedly a reason for fortnite taking its audience so easily). It is also written using Unity and C#, which don't require hopping around in memory, but do make that the most obvious path, which is a trap for people who don't know better.

Farcry is not a game I would expect to have these problems. Ubisoft seems generally technically sound, despite releasing wildly unstable games, but it will take real numbers to get a clearer picture.
One thing that grinds my gears is how the article is shoehorning all these examples of zero-sum bias into a precisely zero-sum situation. It doesn't actually have to be zero-sum for that "bias" to become rational. For example, prisoner's dilemma (which would actually better describe most of the situations put forth in the article).
They're also unreachable by road from the Alaska "mainland".

Sure, “changing the name” fixes the problem if you also...change the rest of the airframe.

It’s really not maintaining the type certification that’s the problem, it’s the aerodynamics of the airframe. If they’d called it a 797 from the beginning it would still have needed the MCAS to get FAA approval because the insane aerodynamics mean the stick forces don’t obey the regulations for constant increase in forces approaching a stall. The MCAS isn’t there just so it can pretend to be a 737.

So yeah changing the name is only a solution if by changing the name you mean fundamentally changing every aspect of it.

The whole story seems so bizarre. As far as I understand it, some kind of fraudster got caught up in a bunch of his own lies, of which being the inventor of Bitcoin happened to be one. We're only reading about it because "Bitcoin" happens to be a frothy buzzword that gets the clicks. Otherwise this would just be some local news case about a wacky person saying the darndest things.

I see similarities between Bigfoot and fairy/elf mythology. Aside from the difference in size, these creatures live "beyond the edge" of human society, in the wild - which seems to have metaphorical significance, like beings "out there" in the collective unconscious. Just like in dreams, my view is that these beings are reflections of humanity, upon which we project latent fears and desires.
Damnit. You got here first.

We do technical interviews but it is more of a conversation about an existing issue or problem in the company. We talk about it like the candidate is a consultant.

Our expectation is that they will ask questions for clarity, probe, and challenge any decisions or architectures chosen to date.

Then they offer an insight, opinion, or story as to how they have solved similar problems in the past.
As I've mentioned at in other parts of the thread, a very thorough design review is at a minimum warranted.

As I've sat down and worked on reverse engineering, and reverse engineering things as best I can from pieces of technical info strewn hither and yon, I'm developing serious concerns over how far Boeing has actually gone in their FMEA.

Given their complete omission or misclassification of the Angle of Attack sensor, I can't really give them the benefit of a doubt that they actually thought through the consequences of more severe, but less likely occurrences like double flameout, or alternator failure. Both of which would represent another critical threat to the MCAS software; which must be active in order for the airframe to be asserted as airworthy.

I'm just not buying it.

Not every person finds every joke to be funny.
As unfortunate as it might be, I feel this situation is the perfect demonstration of the "speed, quality, price; pick 2" conundrum.

They went fast to beat Airbus, cheap as the total cost of the package (plane + training + etc ...) and therefore quality takes a hit.

It happens everywhere but I think we were all under the assumption that surely this industry wouldn't stoop as low.

I've been told a while ago that the engineering of planes involved a fair amount of "duct-tape" (used loosely here) to make all of it work despite the risk involved. I didn't think much of it.

Now I sure have a different take on those words. While growing up plane crashes that happened were rare or their own kind of event(9/11, german pilot suicide, MH370). Therefore people around my age (30) might have bigger faith in planes than one should expect from travelling in hundred of tons of metal, composite materials and fuel going 500+ MPH in the sky.

Naive in the sense that they only address issues such as blocking LAN networks and email spam traffic and there is zero mention of what happens when someone anonymously abuse the service.

The volunteer effort is laudable and quite refreshing but can a VPN relying on volunteers be ignorant of the risks those volunteers incur when they open their connection to anonymous traffic?

I understand that this is an issue that every VPN has to face but there should at least be some mention of how that particular VPN service handles law enforcement and abuse requests, or do they expect the volunteers to face the consequences?

Maybe I’m missing that point and it’s clarified somewhere?
What truth?
For the record, the original example is from the homepage of magrittr (I found it here https://www.fromthebottomoftheheap.net/2015/06/03/my-aversio...) and I'm not trying to angle towards anywhere. I only wanted to point out that the version with a sequence of assignments is not so painful to read (to me) and even the nested version is readable and has some advantages. Not that anyone cares, but I think I would have written something like:

df <- rbind(read.csv('/path/to/data/file1.csv'),
read.csv('/path/to/data/file2.csv'))
df <- df[, df$variable_a > x]
df$variable_c <- df$variable_a / df$variable_b

or maybe:

df <- subset(rbind(read.csv('/path/to/data/file1.csv'),
read.csv('/path/to/data/file2.csv')),
variable_a > x)
df[,”variable_c”] <- df[,”variable_a”] / df[,”variable_b”]

Whether you think these are badly written pipes or not pipes at all, I don't care. It's good enough for me.
Partially this is certainly true and it is easy, since everybody assumes that the costs will increase, nobody is surprised that the reactor which should have costed 3 billion euros will cost over 10 billion euros in the end.

For a technology where the prices are decreasing, this is harder to do.

I worked for Google for 2-3 years, and coming from C/C++ background into a Java/GWT team, this tool (under other name I think, and others related) helped a lot.

The tool, would kick in as soon as you've created your CL (if you are familiar with Perforce, and you are about to presubmit), and offer you changes to do, or it'll do it.

The whole culture, of having team dedicated to a language, and pushing big company-wide changes (LSC? large-scale change, or was it something like this) was really helpful.

Not every company can afford something like this, but it's super useful - avoids useless bikesheddding, unifies coding style, and people would spent less time on code reviews judging the wrong un-important stuff.

What people take issue with is not necessarily one individual's action, but the system which allows rich people to get richer without benefiting the middle/working class. Cost of education, housing and health care keeps rising in America but wages didn't.

I would say it's a combination of zero sum and non-zero sum. If we can allocate resources better, both the poor and the rich can get richer by producing more. But at the same time how profits are distributed is a zero sum game.
So, I'm wondering why it's not upstream in mainline.

The US doesn't need to implement 5G everywhere to be a leader in the field or take advantage of the technology. Just about every major city is an obvious candidate.

This isn't an all or nothing thing. We can continue 4G roll out in rural areas while 5G gets kicked off. If we wait until the entire US is ready for 5G we'll have lost the race. Which is exactly what the article points out. It's a winner take all game.

Look at the current state of the internet. The US is a leader in cloud services, yet many rural areas lack fast internet. One doesn't preclude the other.

The argument that the US should cede leadership in the tech space because some places don't need 5G (may never need it, or are not ready for it) is absurd.

>>> Sure, “changing the name” fixes the problem if you also...change the rest of the airframe.
It’s really not maintaining the type certification that’s the problem, it’s the aerodynamics of the airframe.

I don't think you understand the regulatory regime. Changing the name, creating it as a new airframe, means total top-to-bottom re-certification. That means they can ditch all the legacy equipment and start the control system from scratch. Most of the problems with the max atm are related to systems layered atop that legacy equipment (autopilot, control surfaces etc) that cannot be swapped out without changing the type/name.

It's a good point. Why would the length effect you describe be be associated with age, across many organs, cell types, datasets, and species?

Later he became a professional poker player.
