You're either defining "well-formed" as there being no such thing as a true hypothesis, or you have completely lost me. Either way I don't think there's anything more I can say.

p does not tell you how likely a result is to be true.
I feel like if I were to take program design as being the Wikipedia definition: "...the process by which an agent creates a specification of a software artifact, intended to accomplish goals, using a set of primitive components and subject to constraints.[1]", then I can't see your article saying much about that. Instead, the article points to good things about code created using TDD methodologies. Those code-qualities (coupling, etc) may indeed happen with TDD and may be desirable but that seems distinct from the issue of how-to-design or how TDD is design (one assumes the tests are the artifacts but the point is that details need filling-in).

As far I've seen, the "designing by writing tests" approach, mostly succeeds in the web-apps field where one has an implicit/assumed CRUD/MVC structure, writes tests for behavior and filling in functions based on this assumed structure.

I haven't seen anything about how one proceeds with TDD if one has the more complex task of implementing an algorithm, a language or something with highly structured requirement. I'd be interested in how one would do that.

>If the null is true, the probability of getting p-value2<p-value1 is precisely p-value1.

Precisely. P-value is only defined when the null hypothesis is true.

Apparently everyone else is overlooking this fact.
Interesting, especially the part about the financial situation for coal power. But there is a serious weakness: it presents the false dichotomy between "keeping nuclear and coal, no more renewables" and "reducing nuclear while increasing renewables". There's no mention of the (obviously better) option 3: "reduce coal while increasing renewables, keep nuclear the same".

And what I said about coal power is factually correct. Germany installed 11 GW in new coal power plants from 2011 to date. When you crunch the numbers, that gives you a production of ~80 TWh per year from the new coal plants.

Now, as the article you linked points out, this has replaced old coal plants being phased out. This means their argument of "nuclear power was old and needed replacing, so we might as well just scrap it" could be equally applied to coal.

DanBC is talking about the diagnosis of addiction (or indeed most mental illnesses), not diagnosing any disease.

For example, a patient would likely not be diagnosed with an anxiety disorder if symptoms did not have a marked effect on their day to day living.

This means that the disease model can not be said to be a tool used to enforce normative cognition or behavior, but a model to help decrease suffering.
While both the coal dust and Chernobyl future deaths are somewhat statistical in nature, there is a huge difference that you would acknowledge if you were sincere. The coal deaths are already occurring. They are, as far as I can tell, sufficiently statistically significant that they are not seriously in question.

The future Chernobyl deaths are just that: predictions about what may happen in the future. They think it could happen, but they don't know. And due to the extremely low level of the signal, it will be very hard to tell if they do occur, because as the WHO report states, other effects such as poverty are much more significant.

So, no, the comparison to coal dust is not unfair at all.

But, for the sake of argument, let's completely ignore the coal dust and other respiratory or global warming effects, and concentrate on just the proven accidents. Heck, let's be super unfair and leave in the estimated possible statistical future deaths from Chernobyl, but only consider the documented deaths from coal accidents. That gives us 4000 deaths for Chernobyl and 4000-6000 per year for coal. So even when being totally unfair towards nuclear, it is somewhere between 20-40x safer than coal.

When you level the playing field, you have the 50 deaths from Chernobyl and around 131 others, though that includes lots of accidents not related to power generation. Around 180. Let's double it and call it an even 400. So 10x fewer deaths than coal. Except that's per year vs. since ever. So we're talking around 500-1000x safer.

No matter how you slice and dice the numbers, nuclear power is vastly safer than existing means of power generation, even given the sorry state of the industry today.

Of course, we should still be doing as much solar as we can (just be careful when installing!), and we should improve reactor designs so they are even more safe. For example using the liquid fuel thorium reactors, or concepts such as PIUS, which uses passive mechanisms relying mostly on physical laws to shut down and cool the reactor, rather than active mechanisms that can fail as they did at Fukushima-Daiichi. And hope that one or more of the multitude of nuclear fusion projects makes a breakthrough.
Actually, the Sabbath is from Friday Night to Saturday night. The Christians have perverted this.

If locking your computer in the office is required opsec, then you have already lost. First, you shouldn't have random people walking around the office. Once someone has physical access the battle is already over. Second, rogue employees are still rogue employees, and an unlocked computer is the least of your worries.

With that said, I always lock my computer out of habit.
I didn't tell anyone to do anything because I'm older. I shared that if you do choose to have a family one person's experience is that you will cherish the moments you are serving your children.

I agree. If you cannot trust your co-workers/employees to the point where every computer has to be locked when someone leaves their desk then it is time to move on. If there are rogue employees then the battle is already lost and a locked computer isn't going to slow anyone down.
Ah. I hadn't found that in Mozilla's CSP documentation. Thanks.
One nice application I've found of pbpaste is when I want to count things I find in a browser. For example, to count the (approximate) number of comments in this thread, you can copy all text using Cmd+A, Cmd+C, then run this:

pbpaste | grep ago | wc -l

In this case there are easier (and more accurate) ways, but in other situations you can use it to find the length of a list on the web where it would otherwise be harder.
When I ask someone to follow the guidelines, I'm not implying that they were the only person breaking them. It's physically impossible for us to read all the comments.

The rules apply regardless of whether someone else started it or was behaving worse. Otherwise everyone would have an excuse for everything, since it always feels like someone else started it.
> Statistically speaking, more users get owned via web browsers than via native apps

Source? Seems like a long stretch, especially if you factor in non-windows desktops and all mobile devices.

If you really are concerned about security wouldn't you rather trust basically just Apple and Google or Apple, Google, and every native app developer in the app store?

Having a load of random apps installed on your smartphone is simply less secure than than just using that functionality within a sandboxed and standardised web browser that goes through endless routine security updates.
I'm not an expert, but as far as I know some factors are different between people, for example insulin resistance is inherited via genes.

I wouldn't object to somebody creating, from whole cloth, an electric-stuff-free place, but I do object to people co-opting an existing community that they're not part of and insisting that it become such a place for them. That seems to be what's going on here.
I think it's more about society more easily understanding and thus being able to sympathize with physical pain and disability rather than the visibility of it itself.

Stigma is, after all, more about stereotypes and misinformation (or lacking information) than anything else.

If mental illness also affected skin hue, mental illness might just become more readily identifiable, and (some) people might just be bigoted against blue people instead.
I don't see how does it contradict anything that I (and everyone else) wrote.

You seem to agree that when the null is true and the original result was p-value=0.05, the probability of reproducing the result (getting p-value<0.05 on a second trial) is 5%.

This seems incompatible with your original claim: "If the p-values were accurate and averaged around 0.05, ~95% of results should be reproducible."

Could you explain exactly what do the following mean:

p-values were accurate (that the null is true?)

p-values averaged around 0.05 (that you're taking the subset of outcomes with p-value 0.05?)

~95% of results should be reproducible (that if you take the previous subset you will get p-value<0.05 always in 95% of them? or exactly 95% of the time in all of them?)
My beloved has been a clinical social worker for more than two decades. She's doing her third stint with oncology. In between she's done Alzhiemer's, geriatrics, and a ton of hospice work. I can't second enough the suggestion that quality of life is a primary consideration.

Were it me or a loved one, my first criterion for a physician would be their view on quality of life and palliative care.
This is the WSJ, their audience is going to be a bit more niche than all software developers. For a grad of Harvard or Stanford CS or MIT C6? I'd say that's a reasonable starting salary.
Linux Kernel 4.2 released
It used to be I ran Linux and was unhappy that it didn't cover 100% of the functionality I could get in Windows. then they started approaching parity and I came to terms with not being able to do everything. Now I run OpenBSD on my laptop and it doesn't cover 100% of the functionality I could get in Linux (which was just reaching Parity with Windows for my uses.) But I already learned to be OK not being able to do every single thing. A generation comes and a generation goes, but the earth abides forever.

Actually, they disprove your point, which you would notice if you'd actually read both the link and what I wrote.

First, they show conclusively that "amount of radioactive material" is not the be-all/end-all measurement that you make it out to be. Nuclear tests put a total of 100-1000 times the nuclear material of Chernobyl into the atmosphere, and yet we are also still here.

> It makes no sense to "take into consideration" [..]

Furthermore, they do exactly what you claim "makes no sense". They "take into consideration" the effects of the bombs, and they compare those effects. They do come to the conclusion that the effects are different, one factor being that Chernobyl had more material, a counter-effect being that the radiation from Chernobyl is much more low-level and thus much less harmful (in fact, there are indications that low-level radiation may be beneficial).

But "into consideration" they certainly take. QED.
First, I didn't intend making a "statement". I made an innocent, if not necessarily crystal clear, comment which attempted to give one person's experience to those that have already chosen to have a child. NOT a comment about the merits of having a child or not.

I.e. this hatred targets not officials or politicians. It targets whole population.
The main point of UWB was making it work.

UWB should, in theory, be able to pump a lot more bandwidth down the same wires. Both the cable companies and the phone companies would be salivating at a system that effectively automatically avoids nulls on coax or twisted pair.

However, UWB requires highly accurate, synchronized clocks. Keeping those clocks in sync is non-trivial.

The fact that they could never get it to work over wire means that they had no hope over wireless.

95% of the repeated observations that you make (in the same manner as the observations used to calculate a valid p-value of 0.05) will be consistent with the relevant null hypothesis.

What other meaning could there be? The result of an experiment is not a p-value, but a series of observations. Those are what need to be compared.
Do you need help? I'm completely on board for that mission and personally feel that we as an industry do a really bad job at testing past the evangelizing phase. Teaching people how to actually test code is something I think we need to do better.

1: Seek out care givers and institutions who deal specifically with this cancer rather than institutions that are generally excellent.

2: Understand that most care givers will provide advice based on their circumstances. For example, a radiation oncologist will tend to discount surgery and will tend to advocate the machines they have access to and experience with. This is ok, but you need to keep this in mind when deciding treatment.

3: Select a care giver who will quarterback. It is imperative that the patient trust and respect this person. It is imperative that this doctor understands the patient's goals for treatment.

4: Have an honest conversation with the relative about how far they are willing to go and what their main goals for treatment are. What's more important: quality of life or a cure?

5: Get all legal affairs in order right away, such as a will, medical power of attorney, etc. Decide on end of life care before you get there. Assign a trusted person to act when patient is unable to. Get all paperwork signed, and file a copy with all care givers and institutions. Make sure the family understands what the game plan is and who will be calling the shots.

6: Get a folder and put paper copies of all relevant documents in it, to include legal docs, test results, etc. Always get paper copies of all test results, etc. Always have this folder with you. Allow doctors to make copies as needed, but do not give away your only copy of any document. It's amazing how this one thing facilitates communication between all of the care givers.
As a practitioner of meditation and other things...

... could have told you that one.

Before I started serious practice, if I were to liken my mind to a computer running Linux: out-of-control processes exceeding available memory; processes that call each other and recurse in loops, getting into dead-locks and race conditions; hard storage filled with junk -- files, logs, random crap all over the place; layers and layers of different package management and manually compiled/hacked programs; worms and security exploits hidden all over the place.

And the ironic part: I thought I was doing good.

That's one of the big things I learned, that many of the mental thought streams and habits of the mind I thought were necessary turns out to be ... not. I had attached them to my identity, but they really were not serving me, my friends and family, and my community well.

And here's the kicker -- having spent a lot of time cleaning out my mind, I can tell when other people have their own dysfunctional processes. In even people you might consider well-adjusted, there lurks all sorts of unexamined things in the subconscious, yet leaks out if you pay attention and have the clarity of mind to see it.

I'm no expert, but I've lost two parents to cancer, so I have a sense of the limitations to treatment. With every proposed therapy. Make sure you get an accurate idea of the range of possible results - best and average case time of survival and the impact on your loved one's quirky of life.

Most physicians will advocate the treatments that offer the best hope and prospect for survival, often overlooking the terrible cost to what time the patient has left.

Please don't lose perspective on the most likely outcome while holding out hope for the best.

Pattern matching will only get you so far without static analysis, though?

For example, if I have a function that returns {foo}, and I change it to return {foo, bar}, then a pattern match on its return value that does {Foo} -> ... will fail at runtime, and the compiler won't pick it up, right?

In a statically type language (such as Go), changing the number (or type) of return values will result in compilation errors until all callers have been updated.

A simple 2-step exercise for figuring out what you're really good at
A well formed experiment tests only a null hypothesis.

p-value is exactly the probability that you observed X given that the previously stated null hypothesis was true at the time of observation. The value (1 - p-value) is exactly the probability that you will make an observation consistent with your hypothesis (ie. expected replication rate).

Wikipedia has a decent treatment that might help: https://en.wikipedia.org/wiki/P-value#Definition_and_interpr...
A physician might be your best tool. In cancer, there are a staggering number of clinical trials (which are typically the mechanism to get the latest therapies before approval). In most cases, the standard of care is supplemented with the novel therapy.

If your family member is interested and willing to travel, it would be reasonable for them to ask for a second opinion at one of the major cancer centers and/or to ask if there is a trial in which they might participate.

If your family member wants to stay local, then I'd still ask their oncologist if there is a GBM specialist in the area whom your family member can meet.
"systemd-machined" is systemd in name only. It's not like the init system has built in su functionality, this is just the project's container/vm manager getting some new functionality. This isn't a full replacement for su and it doesn't even come close to the functionality of sudo.
