Has anyone converted exe ouput from CCTV to other formats?
I'm quite surprised some CCTV camera footage burns as exe. Has anyone faced this problem? Can it be converted to any other formats? Googling didn't give me answers.
Do you think hydrogen is not a viable fuel for cars? Why? Toyota seems to be starting making hydrogen cars: https://en.wikipedia.org/wiki/Toyota_Mirai

I'm not sure myself. For now, it looks like just another type of fuel for gas* stations to carry, yet it doesn't seem to offer better range or other advantages.

* now, if hydrogen powered cars will catch on, this gas Americanism will have the right meaning, at once :-)
The most incredibly lucid explanation, of why the Iran Deal MUST be supported
Book Review – The Goal
No what I'm describing is a way of understanding why entangled states aren't spooky. It's also a direct lift from Leonard Susskind so it's not even me doing it. The point is that the state is prepared in some way X, and the state is such that by knowing something about one thing, you also know something about the other thing.

The actual mechanism by which this occurs is only "spooky" if you try and interpret it classically. But if you just accept that "hey, it's quantum mechanics" then it's very easy to understand. Same as I can't visualise a 5-sphere but I have mathematical tools to work with one.

I can't "picture" the mechanism that allows measurements of quantum states to be anti-correlated, but I can use maths to express that behaviour and make predictions about how the universe behaves.
I've only used Scratch a little, but I must admit I found the interface fairly complex and arbitrary, somewhat reminiscent of the complexity and arbitrariness of normal programming syntaxes. As simple a thing as putting one new instruction in between two existing instructions can be a multi-stepped process, creating temporary intermediate structures that work better. But admittedly I didn't power through (or rather, power through with the kid) to the other side, so it might have ultimately been simpler than textual syntax, even if it's not actually easy.

Hopscotch, an iOS app basically like Scratch (https://www.gethopscotch.com/), seemed significantly better in this respect. The quality of your draggable UI matters quite a bit in a graphical language! Given how few of these languages exist, maybe it's not the model but just a lack of rigor applied to the UI challenges of the model.
Why infer derision from a statement that needn't necessarily have been?

That something required a small amount of code or effort is valuable information. And actually, among hackers, usually positive.
Yup, it's all shrouded in huge secrey because it's each team's differentiating factor given that the cars are so standardised. It doesn't reduce how much it fascinates me :)

I will check out some of those journalists. Thank you for the suggestion, I greatly appreciate it!
Actually it's a huge mistake for amateurs to try to follow top athletes' training routine or diet. They have a different starting position, capabilities, and completely different goals. One thing that non-obese people just can't seem to understand when discussing diets is that it's not the same to loose a few pounds before summer and to spend 3-4 years dieting and changing your deeply hard-coded lifestyle in order to loose half of your weight or more. With obese people right mindset and self-discipline plays a huge rule, that's where most people fail. It's extremely hard and demanding to follow the strict behavioral rules for years and it's much bigger problem than just counting calories.
Programming and ?
I've heard a lot of recommendations that one shouldn't just be a (web) programmer with an understanding of (web) technologies, but that one should have an innate understanding of some field and then marry technology into it. Does anyone here have an examples of some fields or industries where they have successfully done this? What made you choose that field? Why was it the right or wrong decision?
Can you answer a) what 'can't' means quoted, b) current body fat (or at least where she is on the graph), and c) whether you have a decent set of scales (which will answer b).

With (a) -- the 'slow carb' thing popularised by Tim Ferris in The Four Hour Body was easy to stick to, had some good science behind it, and most importantly was clearly successful for many people.

With (b) -- there's an effective asymptote which makes it hard to shift the 'last bit' - though it sounds like she's not at that point.

With (c) -- without an accurate measure of body fat & muscle percentages it's basically blowing in the wind as you experiment with changes in your diet. And, lots of exercise - building muscle - will add more mass over the same volume of fat, of course. While carefully weighing food may work for some people, I think if it's not working after several months then you are obliged to accept it doesn't work in this case.

Has she consulted a GP? It's possible there's a metabolic problem (statistically unlikely, but possible).
My Fry's still has a pretty good amount of electronic "maker" stuff, about 4 retail isles including the test equipment. Of course, that's 4 isles in something like 200k sq ft of "stuff", but it's an awful lot more than anyplace else.
My understanding though is that if you have an open connect box on your network it can act as a DDOS, stressing all your infrastructure closer to the customers. Netflix eats all bandwidth.
IBM later developed looms capable of weaving core memory planes automatically, and the price started to drop. Not every far. Around 1970, a megabyte of core memory cost about a million dollars.
For anyone interested in Integrated Information Theory (IIT), Scholarpedia's current summary is much, much better thank Wikipedia's.

http://www.scholarpedia.org/article/Integrated_information_t...

IIT is one of the most horribly abused and misunderstood theories out there, right alongside poor old Godel's Incompleteness Theorem. I'd be wary of anything that you read about IIT and what it implies, unless that information is coming directly from the theory's creators.

I like that Scratch has passed actual user testing amongst small children.

When school is back in (it's summer holidays here in the UK) I must enquire with the head of maths as to how it worked with the average kids, not just the bright ones.
This is not local hidden variable theory. The measurement of one half of an entangled pair doesn't modify the probability distribution of the other half of an entangled pair. There is no modification, just a phenomenon unexplainable by classical physics whereby certain measurements on either system are either perfectly correlated or anti-correlated.
Yes that was my point.
Another datapoint: I downloaded scratch junior for the ipad and felt that it was overtly complex and left it at that. The next day my 5 year old discovers the app and before I knew it had figured out animations and scene transitions. He had previously used another app (Toontastic) and I think that helped with figuring out scratch. Its one of his favorite apps now and he can't wait to show me his latest projects!
Yes, that's consistent with the US. Consumers were allowed to own their phones, sometime in the late 70s or early 80s. I got my phone with a pulse/tone switch in 1982.
Nice article. I remember reading about CORBA in uni days. The article summarized it well as it became a bulky technology with very length and confusing documentation. Industry on the other hand, was ready to adopt simpler technology that focused on web-based protocols, like HTTP (HTTPS).
Then SOA came and it changed the landscape completely with REST-based services, that relied on HTTP protocol themselves.
Finally, it comes down to simplicity. A technology that is too complex to implement and understand will not easily meet demands of constant change and innovation. Hence, as mentioned, it is reduced to a niche technology.

I believe deepstream which received good feedback on HN also solves a similar problem.

With such proliferation of self hosted FireBase, can anyone in the know share their experiences with these solutions?

Idlewords runs Pinboard, a bookmarking site, so I'm guessing he's worried about the impact of other people turning on CSP. I don't use Pinboard, but I believe I've encountered the problem using the Instapaper bookmarklet.

I guess I'll take the downvotes and somewhat agree with them; probably not as far as to say a fireable matter for the first offense. Definitely a strong and unambiguous warning/disciplinary action (repeat offender, however? Fired)

Sorry, I get office pranks but there's no reason to be doing anything on an end-user's workstation without their permission or consent that isn't maintenance or security related. I guess I lack a sense of humor, but I've also seen too many instances where a prank on someone's machine resulted in severely unintended consequences and breaches of trust that rippled through the team.

Just not worth it, IMO.
Online streaming sites and URL obfuscation
Patents should not be linked to commercial success, if that's what you mean by "didn't succeed".
That's the problem with attempting to use Wikipedia as an authoritative expert source: it's not, and it's not what it attempts to be.

The part about marked effect on the life of a would-be patient would not be explicitly stated amongst DSM diagnostic criteria, as it is not a symptom of the illness in question, but rather something most mental illnesses have in common (i.e. a large part of the reason for viewing mental disorders as illnesses).
However, the second sentence in the Wikipedia page on GAD (to which you linked) starts "This excessive worry often interferes with daily functioning".

Seeing "excessive" used in the context of the listed symptoms (DSM-5, your link), I'm hard pressed to view this as any sort of attempt to cull diversity.

As it is rather late in my timezone, I'm not going to go trawling for definitions, but if you're interested in reading more I can recommend NAMI, NIMH, the Mayo Clinic, etc. as good starting points.

As this isn't my area of expertise, I'm in no position to argue the specifics of ODD, but it has always been somewhat controversial [1], and particularly around the release of DSM-5, IIRC. But even if the whole world were to agree that ODD was poorly defined, or pehaps even concede that it was "designed to enforce normal behavior", it would not really say anything at all about neither the disease model, nor the field in its entirety.

Regarding ADD, the major controversy seems to be about possible overdiagnosis, and to some extent about relying too much on medications as opposed to therapy, AFAIK. I think there are several legitimate issues here, some of which are likely specific to culture, some to specific socio-economic contexts, others perhaps to the handling of ADD at large.

The U.S. In Afghanistan: A Fractally Stupid War
One of my favorite tricks when I learned it, because I was already in the terminal, no need to reach over for the mouse to remote into a wallboard via screen sharing.
Untimely Death
The first system I worked on in the USAF had 512 bytes of core memory¹. But it only used 320 of them, as the system was hard-coded to 80-columns (for both punch-card and printer). Since it was fully duplex, it had 2 send and 2 receive buffers of 80 characters each. It would flip the role of the buffers as they became full or empty.

I once had to replace the core memory array when one bit went bad. By pure bad luck, it was in one of the first few columns where the end-of-message sequence was expected, and the bad ferrite meant the system got hung up waiting for an EOM that was never detected. Bad donut. No message. ;/

...I'm not even sure exactly what you do with the hot water that comes out. There won't be room for it in your existing hot water heater, so you'll need a second tank, and where do you put it?

You recirculate water from your hot water tank through a heat exchanger that receives heat from the solar panels via a closed fluid loop. If the heat exchange would cool rather than heat your water, a thermostat turns the pump off.
He was in Nigeria for the BBC, and his Wikipedia entry has this quote about when he asked to extend his stay to continue reporting on the war:

"I was told quite bluntly, then, 'it is not our policy to cover this war.' This was a period when the Vietnam War was front-page headlines almost every day, regarded broadly as an American cock-up, and this particularly British cock-up in Nigeria was not going to be covered. I smelt news management. I don't like news management. So I made a private vow to myself: 'you may, gentlemen, not be covering it, but I'm going to cover it.' So I quit and flew out there, and stayed there for most of the next two years."

So it would appear he tried.

And certainly, in that light being asked by MI6 to actually confirm the truth seems like something he'd have welcomed under the circumstances as another way of having the information acknowledged. And, incidentally, just the kind of things an intelligence service should be engaged in...
http://example.com seems like a good alternative.

Ask HN: Are we in a tech bubble, is so what does that mean?
Congrats on the sobriety. 11 years myself here on my non-throwaway account (don't hire me, then, we'll both be better off).

As for the disease model, and as a partial response to the comment sibling, it is my understanding that the disease model was cooked up specifically to address the "weak willed" label slapped on those that drink too much. If that's true, and I don't have a reliable source to back that up, it would fit well with AA's overall program. IOW, like other diseases, you don't have control over it (if you did, you'd quit), and it is not reflective of a base character flaw, etc.

I dunno, I don't get too hung up on it myself. As you said, get whatever help that fits your model of the world, but get help. I don't even buy into a lot of what AA touts, but simply sitting in a room with a bunch of other folks with similar struggles was a lot of what I needed. (Granted, for a lot of AA meetings "similar struggles" means "the court says I need this piece of paper signed".)
I cannot recommend On Numbers and Games by John H. Conway enough. He demonstrates the surreal numbers by proof which is a wonderful introduction to proofs. The latter section of the book is highly entertaining.

He also worked on cool stuff in the sphere-packing problem: http://www.amazon.com/Packings-Lattices-Grundlehren-mathemat...

I really appreciate is writing and teaching style. He likes to bring his readers and listeners up to his level.
For most development roles that I have encountered, the technology seems to be most important. However if you want to move into business, product, or management, then an understanding of how the software will be used becomes hugely important.

If you fundamentally understand what problem you are solving beyond simply the technology then you can answer questions like "what feature should be developed first?" or "how should we organize our data for the customer?"

You can definitely build a career out of being "just a programmer" and that is what I have done. However being a "clueless developer" is limiting and very successful people tend to have a mix of both code and industry knowledge.
1. Lack of time to completely read a comment means that the first few words prominently determine a persons interpretation of a comment. If it is something they disagree with, anger motivates more than positive.

2. Preconceived notions of big pharma.

I tend to think that people are relativistic in nature, and will think what you convey long enough.

Yikes! Or a law will be enacted, but enforcement will be lax...
as a low level developer all of this confuses me. polyfills as a thing at all, multiple solutions and a service that can provide them (but doesn't actually work!)

this is why web development makes me feel bad... all this time an effort spent solve very easily and classically well solved problems in the browser, because browsers are wastelands of terrible engineering :I
There's this recent review:
http://w3.arizona.edu/~tigger/assets/documents/Nadel-etal%20...

But whenever I read these, I always think they might be getting it largely wrong. In fact, they themselves admit to it being partially speculative information.

I am by no means an expert, but I was neuroscience major in undergrad, and back then (~5-7 years ago) it wasn't known exactly for sure how it works besides the fact that a part of hippocampus interacts with other parts of the brain and that certain things are reinforced with more learning.

Most of the well known and still relevant studies in the field look at people that have a particular part of the brain damaged and how it affected them. Obviously, there aren't too many of such patients.

There are also studies in mice and other animals, but their brains work differently sometimes and other times there are a lot of unrelated variables.

To give you an idea of where the field was a few years ago: I was a research assistant in a neuro-psych lab and we were giving animals drugs in large amounts and then checking whether the cells in a specific region of the brain are damaged. If the CA1 area of hipoccampus was damaged, we could say that it potentially affects memory formation. That was checked by the ability of a rat to solve puzzles it previously solved. Very crude, unfortunately.
Reddit is down; what was it?
How are you saying "the state was prepared before we separated" without meaning a local hidden variable theory? The only way for that to make sort of sense would be superdeterminism, or a nonlocal HV theory, which is definitely not the consensus in QM.

>The measurement of one half of an entangled pair doesn't modify the probability distribution of the other half of an entangled pair.

That's just saying it's local. Not relevant.

Sure, which is my point. DanBC is claiming that the person with the nominal disease is the source of deciding whether it affects day-to-day life. I'm saying that's not the case. Other people get to decide whether it's a disease based on what's normal to them.

An example others brought up was that homosexuality was defined as a mental illness for many years. That's the same dynamic I'm pointing at.

If you're interested in the machines IBM used to weave cores, see: http://ibm-1401.info/IBMCoreArraysIEEEMagnetics1969.pdf

One interesting thing they did was to thread extra cores onto each wire so they could crush the bad cores and still have enough to continue. (They would test after wiring one direction, before wiring the second direction.)
I'm not saying it's an attempt to cull diversity. I'm saying that when the disease model is all you have, it's easy to say, "there is a difference we don't like, therefore it must be a disease".

I think we both agree it happens, though.
Airflow Agari: How Agari Is Leveraging Airbnb's DAG Scheduler
Ah, I see. Probably should've left Winston out of this :)
Seems a lot like CouchDB/PouchDB. Which makes the fact that the words "couch" and "pouch" do not appear anywhere on this page rather concerning to me, because the obvious questions I have are:

1. How is this better than CouchDB

2. How does this differ from CouchDB

3. Why did you not implement this on top of CouchDB

The lack of mention suggests the developers either have no clue what already exists, know that their solution can't compete with existing solutions, or don't really care about being better and are just having fun implementing their own system from scratch. None of those answers make me want to take a deeper look.
Taubes breezily dismisses the Hall paper, which is, methodologically speaking, pretty conclusive. If you're curious about the paper and its implications for Taubes's obesity-insulin hypothesis, I'd recommend these two blog posts by Stephan Guyenet, an obesity researcher:

http://wholehealthsource.blogspot.com/2015/08/more-thoughts-...
I'm obviously not saying that, but it gets said a lot. Anything defined as a disease is seen as a problem, even when the person with it just sees it as a difference. An example people gave elsewhere in the thread was homosexuality, which was defined as a disease for years and years.
