> the current understanding seems to only deepen the mystery of consciousness

Not sure I understand that.

What they appear to have established is that, if you sever the direct connection between the two brain halves, functions that required the direct communication between the two halves is impaired.

I mean, it's interesting to note what those functions are and the severity of the impairment. But there doesn't appear to be any effect on consciousness at all; at least not in the article's description of the effects. Am I missing something?
We have no hope of ever understanding even a fraction of the things in the world well enough to make an informed decision about them. For example, I am not a climate researcher, so I simply don't understand climate science well enough to make an informed decision about the topic of climate change. I have opinions about it, but I recognize those are based on faith of who I think has the best handle on the truth about this topic. Every one of us takes most things in our lives on faith to one degree or another.

And that's why it matters that google curates content. 99% of what they curate we cannot research in depth ourselves within our lifetime. We have to be able to trust that they've done the job of curation properly.

The help page about deactivating or deleting (they are two separate actions) makes it quite clear that your data will be gone, not merely rendered inaccessible, when you delete: https://www.facebook.com/help/250563911970368

That page uses the phrase "permanently delete[d]" multiple times, says there's "no option for recovery," and calls out some information they do keep because it's not actually part of your count, implying that the rest is not kept.
I don't think you missed it. Our corporate website is definitely geared towards marketing to potential customers, and not as much to candidates.

I felt like the GP's citation was probably enough - "pg and Jessica have written about YC's philosophy multiple times in greater detail over the years."

(Graham is regularly quoted on HN without citation, especially in threads about his writing, which is how I classify this one.)
That's what you get for working with other people, I guess.
I don’t see why that isn’t expected. Next time try deactivate it instead of uninstall the app, then there is an option to opt out communication. In your account settings, you can also opt out. I have not received a single email from facebook since then (although I am back on it again).
To add to what sheepmullet said, I think the insertion sort example is exactly the problem with advanced type systems. It takes nearly 300 lines of code to provide the specification.

Somebody has to be able to read that specification and understand that it's correct in a semantic sense. Ultimately, the specification itself becomes a full blown program that the type checker executes. So, now you run a program to try and verify aspects of your original program, but how do you verify that the specification itself is correct?

At some point a human has to be able to read the code and decide that it matches the intent. This step can't be automated, and I certainly don't think the Idris example improves things. I'd argue that it's far easier to tell that this version is correct:

fun insertionSort(arr, int n)
{
var i, key, j;
for (i = 1; i < n; i++)
{
key = arr[i];
j = i-1;
while (j >= 0 && arr[j] > key)
{
arr[j+1] = arr[j];
j = j-1;
}
arr[j+1] = key;
}
}

It's sounds like your problem is proprietary Windows, and I feel for you. Other than the fact that Nix runs in Windows, it can't really help you with the consistent deployment thing.

We really need something we can point to to express and legitimize our frustration with Windows to those who don't understand how much more effort it takes to deal with a totally incompatible proprietary system.
I thought this was an interesting recommendation...

"Memory-safe languages can eliminate or substantially reduce the likelihood of many classes of coding errors that have often led to exploitable vulnerabilities. These include buffer overflows, null pointer dereferences, use-after-free errors, and references to uninitialized memory. Rust and Go are relatively recent memory-safe languages; others include F#, C#, Python, and Haskell. Developers who select other common languages (e.g., C, C++) that don’t provide memory safety need to provide evidence that their implementations avoid these problems." (pg. 12)

You described it very well. Thanks for answering and sharing your experience.

Yeah people seem to find a reason to laugh or be happy even in the worst conditions.

It interestingly goes the other way too -- people who seemingly have everything and more sort of get used to it and still find ways to be unhappy and resentful. Even over the littlest things, like say the barista making the wrong coffee or someone cutting them off when driving.

C (or really any traditional programming language) doesn't really map to an FPGA. There are some compilers out there that attempt to convert traditional C code to state machines for FPGAs, but FPGAs are really a completely different paradigm. You're actually describing digital logic, not a sequence of steps.

That being said, there are soft-processors that have been written in VHDL/Verilog and can be incorporated into a FPGA design, and those CPUs do often have GCC support (Microblaze Xilinx, NIOS 2 Altera, plenty of MIPS CPUs out there, etc.).
You're looking for "posterity," not "prosperity."

Haven't ever had a Facebook account, but I've encountered the deactivation-deletion dark pattern before, most recently on Twitch.

I think, it's a matter of them being required by law (won't be the case in all countries) to have true account deletion, but then they try to deflect as many users as possible from actually deleting their accounts by having an account deactivation option and having it in a far more prominent place.

Not too verbose, would be my recommendation. Though, that may be because I have the tendency to be rather wordy and I suspect they are currently all pressed for time.

This is the third time it has come up recently, at least for my comments. I really lament the quashing of the citizen scientist idea.

I'm technically a scientist, albeit retired. I don't want a pedestal, nor an ivory tower. Someone mentioned that they weren't a real scientist. Yes, yes you are - so long as you follow the method.

Scientists aren't ordained. They are just people following a set of rules established by the Philosophy of Science. Anyone can follow those rules.

I encourage everyone to try to apply them to learning new things. I encourage them to get involved, to experiment, and to share their results. Ask questions. Ask for data. Ask why.

Intellectual curiosity is one of our species' defining traits. Giving that up and just accepting answers goes against the principles of science.

There are very, very good odds that they'll get the data they want, so long as they find the correct person. On a project this large, they should be able to find that person.
Why would someone do that?
Please thank you friend for me.

I can't speak for everywhere, but Donald Trump's supporters in the United States certainly did trend well-off, majority/white, and male. My theory is that it's not immediate problems gripping them--it's that they see other people catching up, and the idea that it's zero-sum has permeated the game.
Great time with family with this one
>How does a brain, consisting of many modules, create just one person?

The same way a population, consisting of many people, creates just one state? The state is not the people and the people are not the state, yet both exist.
Not sure what would be the evolutionary purpose of that. I doubt that many of our ancestors survived brain split and managed to reproduce in order to pass the genes, so having that feature would probably mean it's necessary for something else... sounds like a long shot for me though.
Depending on what you're googling for, it usually provides enough context to know the phrase means the MS server.

Plus, even in colloquial language, we don't ever call a database server an SQL server. They're referred to as databases, or by their names.
Contract workers or Uber workers is a bad deal for all, with some short term gains.

For a worker, yes, its less of office politics and having to deal with crappy co-workers. But that is how you grow. I learned so much when I am working with people than being all alone. So, having couple of people approach the same problem in different ways, helps you learn, teach & grow. I was learning something new everyday, when I was working in a team. Plus contract jobs are effecting the basic needs of human beings - "food, clothing & shelter", due to the very nature of uncertainly. Basically I am more worried about the basics and not as focused at my job when I have a full time job. I feel that I am just completing the task at hand to get paid. I don't analyse the issue and try to find a solution or seek for some improvement. Plus working in a specific domain for a period will help in gaining experience and you have build up skills.

For a employer, how much ever you document a solution, there is going to be knowledge gaps. Only when you have someone working on a problem for a while, will they be able to come up with a better solution. Each employee comes come a different background and will view the problems differently. That will bring about a nice work culture.

Team work is not given enough credit. Instead, there is always the focus on one rock star that does it all. I personally feel that for that one rock star to actually perform, there needs to be a team behind to support.
China has actually started partially enforcing the trade sanctions. They aren't in favor of nuclear proliferation either and won't knowingly allow nuclear weapons components through their territory. So containment is still mostly possible. It doesn't have to be an unbreakable barrier, just good enough.
Yeah, I just checked. It's definitely the most complex. Well, other than the thing in Nebula VOQ 34E, but that's a given.
Here are all the other fatal shootings from Sunday that you haven’t heard about
About 12 years ago I deployed Windows Terminal Server in a corporate environment, and used PXE boot on the client computers to start a basic Linux distro that then launched the 2X client to access TS. Right now I'm creating a reference document for a VDI deployment using VMware/Citrix/TS. I've briefly looked at the NoMachine client by installing it to a Win10 computer, and the performance of NoMachine is worse than RDP to the same computer over the same link. Since you're happy with NoMahchine do you know of any optimization techniques for it?
The big piece of LIGO was the incredible effort that went into data analysis and verification. The second these things were detected a monumental effort went into confirming it meaning when it happened again the methods were already in place.

My non-specialist take on it is that, even if what neurons really do is hugely complicated, we should be able to approximate it with something pretty simple and anything sorta close should work. I believe this because real brains are incredibly fault tolerant and can take an absolute beating while still continuing to function 'well enough'.

I'd be willing to bet that once we understand the basic functioning, we'll be able to build a working brain using a few different types of neuron which operate on relatively simple rules-of-thumb, arranged in a few different basic structures which are internally relatively homogeneous.

First off, just a bit of a nitpick, but as I understand it the Evangelical/pentecostal side of Christianity is doing pretty well, or at least it's not suffering from its members literally dying off (far from it, in fact). That was also my experience from about five to ten years ago.

Second, I'd argue it's way to early to conclude that abandoning religious moral guidance is a success. At most it's an (unprecedented?) experiment that so far seems to work.
I mostly agree that the results are not always good.
As someone who read the original style transfer paper, and implemented it, I disagree that it is applying a mechanical effect. Maybe I'm biased but the algorithm use a pre-trained CNN on object recognition.
The CNN develops a representation of the image that is more and more abstract along the layers of the network. You can visualize the information in each layer by reconstructing the image only from the feature maps. And when you do this you will see that the network, learns the objects and textures
of the image compared to its pixel values (pixels -> edges -> regions -> objects, etc).
It really helps to have a Googleable name. You will get adopted faster and your community will grow if people are able to Google "enable 24 bit color Guacamole" rather than the generic alternative. Also generic language simply can't represent the sheer variety we have, or explain what projects do to newcomers who don't understand the generic language anyway.
If you can, you should consider updating to 11.1 instead.
Yeah, TeamViewer is certainly decent enough, but I'm always looking for other open source remote desktop access mechanisms (especially now that my current day job is pretty restrictive with the laptops they issue us). I had never heard of this Apache Guacamole, but will certainly give it a try!
The very odd thing is how the susceptibility to the name has switched political sides. Now the populists/conservatives don't want to hear about Russian stuff, and the liberals are sure that Putin elected Trump. I caricature, but not by much.

This is my pet peeve too. Speaking as a physicist, if I ever invent a Quantum Fusion Plasma Turbine Terraformer, I'm totally going to name it the Visual Java Rusty Lispy Scripter Plus Plus. I figure that might pollute the namespace for programmers enough to show them what they do to other fields. Revenge!
> All the unsafe GC code would be abstracted away into a module and would be more obvious to those looking at it that they will need to be watchful for undefined behavior.

That code that could be "abstracted away" would be "virtually all the code" in my example.

> Maybe for developers that are very familiar with the race conditions of parallel code, but definitely not for most people. Even seasoned developers will make mistakes with simple multithreaded code.

I'm not talking about manually guaranteeing absence of data races. I mean absence of data races as a language feature.

This is not at all what I was talking about. You completely misunderstood me.
> I agree with the article. I think more humans do need to be added to the "decision-making" process.

Not really useful when most journalists already demonstrate how even professionals can't check their sources.
I agree, people need to be pushed quite far to literally revolt. As long as they have something to lose (and they can't afford to lose it or are willing to, such as football and beer), they will behave .

But societies rise and fall on a greater timeline than one's lifetime. Wages haven't risen since the 70s or 80s and there is still no revolution, so it will take time. But recognizing that there is a problem is the first step to fixing it, before it's too late and it snowballs. Or perhaps ups and downs are unavoidable, and it's best to just plan for yourself.

Either way, the declines in birth rate, marriage, and equality are, by all indications, due to structural economic factors. Society is changing, maybe not breaking down to the point of violent confrontations yet, but it is something to watch out for in the future, but it could take a while.
I suggest listening to the video [previous 2]. That political opinion is explicitly designed as a racial slur.

> It's just a very very weak one, so weak as to be almost entirely useless.

Weak and strong aren't meaningful terms. A machine ISA might have an inexpressive type system and/or an unsound type system (because it conflates addresses and integers).

> And the reason floating point registers are often separate from integer registers is not to provide this kind of "type safety", it's due to history and architecture.

No, the reason is performance. And we get performance by making statically known distinctions between datatypes, which is what the original poster asked about.

Intermingling the integer and floating point circuitry so they access the same register file would never improve performance over keeping them separate. You'd need longer wires to place them both near the same register files to minimize signal latency, an the added signal delay alone ensures lower performance.
Newsvine was great during its heyday. I never partook in the citizen journalism side of the equation, but took great pride in curating interesting submissions and the discussions that ensued. For at least one period at the end of 2008, when I was a senior in college, I was at the top of the leaderboard and harbored ambitions of moving to the west coast and working for Newsvine in technology. Alas.

The discussion is what made Newsvine for me. It was friendly, well-informed, and Made Everyone Smarter. These days, I don't even think about wading into the morass that is the comments section on news articles. I miss that, though it's certainly tied to the size of the community—which itself is tied to the ability to moderate effectively. Much credit to Tyler and the team for keeping us on the rails.
Is this number adjusted for cost of living?
I already said all that a lot more efficiently in my comment.
Well this seems one of the million open source Java project from Apache. At one point names were straightforward like 'commons-cli', 'commons-httpclient', 'stringutils' etc and libraries useful for large number of programmers. But nowadays it is mostly half-assed 'frameworks' with fancy name.
> I think those few, crucial pieces of hand-written assembly language one sees from time to time disagree with you.

I still don't think so. For example, plenty of silicon is spent on branch predictors simply because addresses and integers aren't distinguished, in general, thus permitting more expressive but costlier code.

Execution would be much faster if integers and addresses were forced to be distinct. Static typing pretty much always improves performance.
Yeah I'm not sure this is greed at all. I don't think it rises above poor judgement in risk analysis.
