Did you ever the pleasure to work with a Six Sigma Black Belt who had the most of one week statistics training? I am one, but honestly this is just enough to do some back-of napkin number crunching for purely operational purposes. That you need a math PhD is maybe exaggerating as well on the end of the spectrum.

That being said, the abilit to talk to domain experts and accept their experience is one of the most important skills for a true data scientist. Without proper context all the data in the world gets you nowhere.

One thing I don't like about my source code is it "doing something interesting".

I like my code to be boring. I like my frameworks to be boring. I like my APIs to be boring. So I can focus on important things in life (or even the important things at work), and be done with it.

That's highly inaccurate. The gyroscopic effect is not everything, but it does get stronger at higher speeds. That's why even a simple wheel without any frame or steering mechanism will run mostly stable at high speeds. So when going at high speeds on a bike, it indeed is more stable than when going slow.

The article you link only claims that the gyroscopic effect is not everything stabilizing a bike.
> That is very silly. How would a descriptive fact about the world (e.g. what is of evolutionary adaptive advantage for humans) ground an objective moral 'ought'?

We are basically talking about different things although we use the same words (descriptive vs normative sense). It's basically defining words (like "ought" in the context of objectivity) and drawing conclusions. Calling my line of thinking "silly" shows me that there is a chance that I didn't specify the semantics in a way that they make sense for you in that context.

Parent asked

> Are you arguing we can root morality in objectivity?

And I hinted at the possibility that you could use certain scientific insights to build a framework which uses a certain kind of objectivity (which depends on your definition of objectivity - here I use it for scientific thinking).

If this fits someone who is scientific-minded (it certainly isn't enough for me to be a sound framework, so I agree with you that making descriptive facts a foundation for ones' morality is definitely lacking in some important qualities), this line of thinking can be used by that individual to say "I think morality has roots in objectivity".

I'm not stating my opinion here, it's more about arguments that could be used by individuals who want to have this kind of framework for themselves. I definitely see the limits in this (like you), but I was just trying to answer the question from a different angle.

Basically I was talking about people who could say things like "There is no god, we haven't seen him and the meaning of life is to reproduce" - scientific-minded people who elevate descriptive aspects so they become the foundation of their belief system. For them, there certainly can be morality in objectivity with those aspects (psychology, game theory) - although you and I don't have to agree with that because it may look one-dimensional to us.

edit: I found that perspective interesting because there are people who call themselves scientific-minded who dismiss the possibility that morality has roots in objectivity, so I found it worthwhile to show this angle.
I don't think a duckduckgo query is a fairly representative study of dreadlocks in cultural significance. A search engine will also turn up thousands of hits for "do vaccines cause autism", lots of which will say "yes".

True that. Adding complexity is easy, keeping things at the right level of simplicity is hard work and requires skill. Not just for coding.
In MN, since the I-35W went down, I’d go so far as to categorize the bridges that have gone up as appearing “overbuilt”. Which is probably a good thing. It at least appears to me like they’re taking bridge safety seriously. Inspection of existing bridges kicked up strongly, and Dailing bridge inspections make the news.
Actually I believe there are 2 different data. The number of level of the building, (from which you can extrapolate an height) and the actual height in meter (which is much harder to estimate as a random mapper). Street Complete prompt you for the former IIRC.
There are many, many institutions preforming global IPv4 scans daily and many tools that allow you to do it[0][1][2]. The trick is to "Be a good citizen", work with a scan friendly host, signal your benevolence, and limit the rate at which you scan. Also smart to black-list DoD networks. If you don't believe me setup a honey pot and open up a popular udp amplification port. Haven't done so myself but I would expect many instances of scanning would be seen everyday.

If you need the shim anyway to fix it for your users it doesn't particularly matter to you at what point Apple fixes this. The fix will take months to percolate in the best case anyway. It seems you also need an Applie-ID to even report a defect.

So to me the unwillingness to help Apple with this is not a strange response. Especially considering Apple made Safari closed-source.
Maybe vector-based CRTs like in oscilloscopes can be made small enough to use in headsets (if they haven't already). Either project floating text on transparent AR glasses or project a text layer on the lower resolution graphics display. I'd prefer the AR approach if it means I won't need a $500 GPU to generate floating text.
Badly designed systems aside, for most systems that currently exist or have existed in the past, there is little or no documentation that is worthy of existing. Most comments in code and the associated documentation in manuals fails to provide the reasoning as to why the code exists, why it is written that way, what underlying assumptions have been made, etc, etc, etc.

I am going through a process at the moment of documenting all of my local codebase. It will, in turn, be turned into a literate programming base. The problem I am finding is understanding all of the assumptions that underlay the original code. Why was it written this way or that, what is it trying to do, is the code actually doing what it is supposed to do?

There are, at present, some questions that I am having difficulty answering and this is my code. How much more difficult is it for someone to come in and look at a historical piece of code and follow what the original authors and designers were trying to achieve and what were the changes that have been made over time trying to achieve.

Documentation at the level we need to be able to adequately maintain any code base is just not done - it is very hard to do and to do so in a way that will help future people manage and maintain that codebase. On of my projects involves restructuring the code base. However, I need to understand the history of that codebase and that means talking with those people who are still living who knew the original authors and give an oral insight as to why things have been done the way they are. This oral history has to be written down and the codebase documented with it. When that information is in place, why the code is written the way and how we can now rewrite that code to be more effective is now achievable.

If we then put on top of missing history and documentation all of the bad designs, well, we are then facing even bigger problems. Then we put on top of that all the egos and politics involved, we get an even bigger mess.

So just reading up more doesn't actually help, because that which is needed was never written in the first place.
Hm, I don't get it.

There is maybe a use case for VR to add immersion for games (like space sims or racing games), but why would I want to have a device on my head to look at a 2D canvas?

I mean it's a nice tech demo, but it seems like the 2000ish hype around these 3D-cube window managers that ... looked cool, but otherwise don't add anything to your workflow. Do people really want to work (e.g. develop) with a VR in a 3D environment?

Yes. I work with QNX6.6 daily. I also worked with QNX6.5 and QNX7.0. It's a real blast to work with the mikrokernel. It's a really cool system, and the kernel stability is excellent. Feels good that when a low level driver crashes, your system just goes on as if nothing happened (except, of course, the applications that need this driver). Speaking of drivers, the driver situation on QNX is a bit sad, simply because there are few drivers and the ones that exist aren't as high quality and well tested because QNX is niche. Still, if there was a QNX environment that is as progressive as Linux Ubuntu (concerning GUI, drivers, etc.) and OpenSource, I'd definitely use QNX as my main OS.

> The idea is that it's temporary pain for long-term gain.

No, it's not. There's absolutely no sense in which there is a "long-term gain" from imposing a tax on US consumers because the government decided they were buying the wrong products. If you have an actual argument to make in favor of these taxes, please make it. You're just parroting a talking point and providing no justification for something that doesn't make any sense.

If I must fix it for my users right now I must use a shim. Letting Apple know about this will probably allow me to remove the shim after months have passed. I can see why the priorities are on the shim here.

I also just checked and you need an Apple-ID to report a defect in Safari. Which I for one don't have.
Can you link the game directly. As I press the heading and it goes to the game.
I'm not sure if it's just about the 2D canvas. With WebXR (I think - I'm not too up-to-date on the field), websites can also offer VR examples. You will need a browser to discover them, but they can still be immersive - you just also need a 2D canvas for regular websites that get you there.
Posting anon for obvious reasons.

The Product Managers at our company seem to:

1. Optimize going to lots of conferences which always happen to be at great locations

2. Cant provide more detailed "what did you learn at the conference" responses than useless boilerplate "customers are excited about xyz and there is huge growth there"

3. Create "partnerships" that sounds great with nice press releases but there is almost never any retrospective on how much sales $ these partnerships brought

4. Usually know very little about actual platform constraints and push cool-sounding ideas which incur massive technical debt

5. Love to create one-off demonstrations products that conveniently avoid hard questions about the technical platform and nicely shine to the c-suite and stick the ugliness of technical debt they bring to the engineers

6. Spend most of their day on Linked In hunting for the next sucker company

2. "Every senior dev I hire must have done one of two things: either ran their own business or was a one-person shop. That's how I know that they know how to do whatever it takes to get software built and deployed."

3. "Our customers can buy this stuff anywhere. They buy it from us because of the value we add. That value includes the ones and zeros that we developers add to every product. The sooner everyone understands that, the sooner they will see I.T. as an indispensable component of our product and not an overhead department."

What kind of skiing are you talking about? I've never once seen anyone wear a helmet for cross-country skiing, and I wouldn't think it's necessary anyway. For one thing it's usually walking pace, but also snow is soft.

Maybe it could improve ergonomics? A lot of people suffer injury from the posture required to sit at a desk looking at a monitor all day.

I think that Act 22 folks are often the "barely rich" or "incorrectly categorized as rich", where differential tax policy actually has an effect on their lifestyle (and therefore more strongly drives behavior).

Take someone with $5MM in investable assets. Using a simplistic 4% rule of thumb, that can generate $200K of income per year. Tax that at 4%, and you have $192K to spend. Tax it at a blended 25% and you have $150K to spend. At that level of income, $3500/month is very much a noticeable difference, IMO. ($16K/mo vs $12.5K/mo spendable.)

Now, consider that $150K/yr living in the mainland US goes farther than $150K/yr on Puerto Rico, and someone with $5MM and eligible for Act22 isn't going to move to PR without Act22.

Peter Schiff's quote in the article sums it up very well, I think: “Who would come to a bankrupt island to pay high income taxes?”
It's more like: you're in a certain group, you get hired, and you know that the company that hired you has this policy of prioritizing hiring from your group. You spend your days in that company wondering whether you got are there because you're good at what you do, or merely because you are member of the prioritized group. I wouldn't want to be in such position.

> I don't think there's any need for a breakthrough in order to have world wide massively adopted electric cars.

It's not a matter of opinion. candiodari posted the metrics just a few comments up. Gas/Hydrogen has 4 to 8X better power to weight ratios.

> The only bottleneck right now is battery production, not even demand.

No. It's also demand. Most people want big gas guzzling trucks and SUVs.

> That makes it everything but "steady" and it will take pretty much everyone by surprise, like any other technology before (computers, internet, laptops, smartphones... and petrol cars)

S curve applies to something "revolutionary" or better. Electric cars aren't better than gas cars. Regular cars are cheaper, get more mileage and are much more efficient (and powerful) than electric cars. The only thing going for electric cars is they pollute less.

Smartphones did something that telephones couldn't. Computers did things typewriters couldn't. Cars did things that horse carriages couldn't. That's not the case between gas powered cars and electric cars.
It's good practice. The important part isn't who screwed up, it's how do you fix what got screwed up and prevent it in the future. When you play the blame and punishment game it just makes people more reluctant to admit they screwed up and you start finding out about problems, or finding their cause, only after even more damage has been done. Your employees should only have to worry about their ass if they keep making the same mistakes over and over.

Presume that you are a software engineer. Your career and other people's lives depend from your producing systems that operate safely. You also have to make risk analyses and meet performance goals.

Your operating system executes different program images for every successive execution of your program, picked in an unpredictable manner.

How do you prove that every possibility passes the safety tests? How do you measure the risk of this random selection? How do you know when you have done enough simulation?

How do you match up software randomization with the ISO 26262 concept that all software faults are systematic and not random as (some) hardware faults are?

How do you prove that memory allocation and execution always meet performance goals? How do you construct and perform reproducible performance tests? How do you demonstrate that your measurements are meaningful?

Software engineering in this case involves thinking about all of these questions and more besides.

It appears (to me, at least) that the current state of the literature on ASLR is that it is treated as a succession of theoretical arms races, which new defence militates against which new attack, and almost no attention is paid to the concerns of actually deploying it in a larger system; and the current state of the literature on functional safety is simply "we will assume that there are no randomization processes in the software" (from an actual paper presented at ESREL 2016).
