Yeah, it would require quite a bit. Note that while it can input a massive frequency band (10M to 3.5G), the sampling rate is quite small (~31MS/s). Would work much better as a spectrum analyzer than a time domain viewer.

You can definitely use it as an oscilloscope, but it's non-trivial and has many limitations. Recommend getting a cheapo analog one, or if you're already at the normal SDR price range, just going for a Rigol
Thank you so much. OpenAI gym and Universe have been, to say it lightly, a pain to use on Windows (generally through hacks like the Ubuntu subsystem, etc.). And let's be honest most video games are Windows native.

That is one of my favorite movies. And while the computer in the movie is named Colossus, it has nothing to do with this story. In fact, the real Colossus was still classified at the time this movie was made; use of the name is sheer coincidence.

I mean it could be bad for business for the company that has 1/4 of the global population in its pocket that is trying to continue to expand its user base.
When I started out, I thought you would be assigned work with the expectation that you could complete it. I basically murdered myself for a half a year and developed minor health problems, since I was broke and worried about losing my income. As my energy and stuff deteriorated I lost the ability to concentrate or do much work, and I started getting warnings for not working fast enough etc. At that point I felt manipulated and got angry, and thought that actual work output counted for nothing, since it just lead to raised expectations, accusations of not working hard enough, and no upside.

So I spent half a year doing the minimum amount of actual work I thought I could get away while spending the rest of my time socializing and helping out coworkers. I think this basically made my manager lose her mind. She started badmouthing me to my skip level and using me as a scape goat for our project not working out (we were a small team and I went from the highest output worker to the slowest) but all my skip level manager would hear from other employees was how great an employee I was. Eventually she seemed to start avoiding me, and then went psycho and left the organization.

Overall, I think that this only works if everyone is straight forward and doesn't do any creepy things out of greed or ambition.

Well, then you jumped in to reply to my post with a useless claim about something happening that we all already know.

Again, I am not arguing the opposite is proven! You are literally putting words in my mouth.

You are arguing a totally separate point, and just decided to reply to me, for some reason. Please actually read the posts you are replying to and stay on-topic. Your off-topic rants are useless, and you have wasted a lot of my time trying to work out what the hell you are going on about.
Tyler Cowen interviews Larry Summers on Macroeconomics, Mentorship, Complacency
At least here in Brazil, airlines are expected to authenticate you at boarding time and not a second earlier. This is the sanest option too, since they will have to authenticate you at boarding time anyway, and anything earlier will at most cause a mild economical loss for the company.
This will save trillions. MAGA

> 1) Generate your application. This is a single command line command. 2) Edit it a little, add a text box and some buttons. 3) Deploy it to google app engine; this is a single command line command, too.

That will create a toy application. If you want to create a production application you need to handle data. To handle data you will need:

* Tables / lists to display the data

* Views to edit and display the data

* Forms to edit the data

* Auditing of the user actions

* User authentication + authorization

All these are not trivial to create in an SPA especially since you'll always need both server and client side code. With django (or rails, or spring or various other server only frameworks) you won't need to write client code and most of these components will be auto-generated (at leas their default values).

For your last comment, I also agree that if you know rails then you don't really need to learn django since they are both similar (however I do profer django because of its no magic philisophy and because python is a better language than ruby) but I believe that you also don't need to go the SPA route until somebody specifically asks for an SPA and has good reasons asking for it (or you want to learn the technology and modern frameworks that surround SPAs).

As a final comment, I have to say that really like all those modern frameworks (especiall react and redux) but I won't consider them for my day-to-day job since instead of creating something in 1 week I'd need 1 month using these technologies.

The article focuses on inherited diseases, but that is a proving ground for the later, larger market of enhancement. An order of magnitude more healthy people will be willing to undergo gene therapy to gain greater muscle mass and less fat tissue (myostatin / follistatin) or greater stem cell activity (telomerase) than is the case for patients with serious inherited conditions willing to undergo gene therapy.

The breakthrough waiting to take place is the development of a methodology of reliable transfection of large enough number of cells to produce the desired outcome in adults. That seems to be not that far away, but it isn't the case today; the gene delivery mechanisms work, but that isn't the same thing as succeeding in altering a sufficient number of cells every time.

This is one of the reasons why there are no clinics offering enhancement gene therapies via medical tourism. That will happen soon, however, in a similar pattern to that followed for stem cell therapies at the outset of their clinical availability.

Have you read the Jennifer Luke study? The pineal gland is the only organ in the brain that is not behind the blood brain barrier. It is responsible for regulating our circadian rhythm. Melatonin synthesis is a core aspect of our health.

Jennifer Luke found that in gerbils, high fluoride hastened female sexual development and was associated with a diminished circadian rhythm.

Even if fluoride levels in water are "fine" (as in "deal with it.") for most people, its mass medication and there are likely people who are adversely affected by it. It's absolutely unnecessary.

I doubt you could do anything to a bike frame with this that you couldn't with foam-core carbon fiber. The advantage 3d printing over CFRP is cost is constant with intricacy and number of joints. That means its best for skeletonizing to a small scale or lightening really intricate parts, and expensive for large, sweeping parts (like the shape of a frame).

So, you could skeletonize things like brake levers/mechanisms to a much higher degree than with older aluminum alloys. The ultimate limit to skeletonizing something is the tensile strength since each member basically becomes a wire eventually. At that point its strength is determined by the tension it can sustain rather than the bending force.
It prevents people from waiting to enroll until they're sick.
I figured you were just looking for something to toy with. I figure that turning this device into a scope is not going to result in an accurate scope nor something that would be useful beyond entertainment value.

It seemed like a good idea to recommend something cheaper, easier, and better documented. Besides, who doesn't want to use their mic jack as an oscilloscope? ;-)
Same reason that they don't want to cover pre-existing conditions. If you're young and healthy, you could forego insurance entirely until you got sick and then sign up. Or you could sign up for the cheapest plan and then flip to the most generous if you found out that you were pregnant.
Are you not just projecting your own bias? Governments regulate cars, TVs, toy safety, cell phones, etc.
I was also curious about this. Don't have enough data on how this works in real life. What is to say that you won't spend more time on entertainment now that you have a separate device for it?

I've tried to keep up to speed with the numerous Reddit threads[1], but from my understanding, even if the GOP are trying to sabotage the signup, this is just par for the course when it comes to GOP tactics to get their own way... but surely people can plan accordingly and still sign up?

It's one of the things that attempts to ensure that people don't forego insurance while healthy and only buy it once they get sick. You have to prevent that behavior if you want to also allow sick people to sign up without massive expense.

Stick one of the consumer security cams in your house and this becomes pretty convenient?

You could even watch them on your phone if that's your thing.

Not that this won't be a tough sell, but (for people without pets), this doesn't seem completely crazy.

Could have a cost edge over chilled delivery boxes.

Not really a thing I want, but I would continue to bet on the general population choosing price and convenience over privacy and security.
This reminds me of my student loan servicer, they don't take any online payments on Saturday or Sunday even if your payment is due on Saturday or Sunday.

This is not an insurmountable obstacle, but it will make it harder for many people, and anything that makes it harder will result in fewer people actually signing up.
Whatever the commonalities of the processes of the various process, I don't see why a process of creating an industrial 3D press that can create "real" solid objects wouldn't eventually allow a transfer of that tech to consumer-grade printers.

Altogether, it seems like when an industrial 3D printer can fully print itself, the path to making printer consumer grade would be a lot clearer.

> Another poster mentioned it violated GNUs guidelines but I doubt that is true.

I mentioned it too in this thread, here's what I am referring to:

https://www.gnu.org/licenses/gpl-faq.en.html#RequireCitation

I have to assume that gnu parallel is currently meeting gnu's guidelines here, perhaps by allowing users to mute the nag. I do wonder if this particular guideline was written specifically for parallel.

> It does make me curious as to when people stopped listing their tools.

That's an interesting question! Certainly some people still do list their tools.

My story isn't entirely different than yours, but I've continued to publish occasionally since my thesis, as well as edit and review papers for several journals.

For me, I think it comes down to methodology. If a program used represents previous research, then it should be cited. If a program used does factor into the methodology of the paper, then citing it for reproducibility is a great idea. If either of those are true with parallel, I will absolutely cite gnu parallel.

But parallel is generally used only to speed things up, and does not affect the methodology at all. I guess it could be nice for reproducibility, in case there are bugs. But if parallel is only used incidentally like that, and the publication isn't about parallelism, and parallelism doesn't affect the output, it's not something you should cite. The journals I've submitted to would normally ask you to remove noise like that if you included it. (And as an editor, I've asked people to remove non-academic references, or at the very least footnote them instead.)

I realize it's not a widespread problem, but take the idea to a logical extreme -- do I cite all my tools? Should I cite my version of Linux, and include that I used zsh instead of bash? I process my output using sed, Perl, awk, Python, numpy, and I did my user experiements using Chrome 55 with JavaScript and Angular. The list of tools I use is very long. As a paper reviewer or editor, I'd be annoyed if I had to wade through that. And the number of tools that affect the methodology is small, those are the ones I care about.

An author should simply include their entire source code as a single citation, rather than individually cite any tools. That satisfies reproducibility without adding any unnecessary noise to the appendix, or treating gnu parallel as a part of the research when it's used only incidentally.

Also, Ole's really asking for PR more than he's asking for academic citations. There are lots of other ways to give him PR and help him. I feel like the emphasis on academics in his citation nag is slightly separate from the overall goal.

I think you and I are actually not far apart on this at all. Everything you mentioned Django does well. And so does Rails. And I sorely miss the beauty of Django admin in the world of SPA's.
I think it does, try it as:

sleep 5 && (echo hello > test.txt)

and you'll see it creates the file only after sleep ends.
I'm eagerly awaiting social VR. Since playing multiplayer games allows people of now to have unparalleled social interaction and insight into other person, being able to freely explore virtual worlds together would greatly increase integrity in society, even if at very least teaching various social skills.
I don't understand what you're trying to say. I would expect these two commands to behave differently:

(sleep 5 && echo hello) > test.txt
sleep 5 && echo hello > test.txt

"our intuitive notion of order of operations on its piping" -- I don't know what your intuitive notion is, and there is no piping in your example. Piping would be:

sleep 5 | echo hello (this is an odd example, but it works)

I also don't see any race condition in your example. A race would be two processes accessing the same data.

They are redirects, and the way redirects like > and < work is to:

1. open a file

2. change the global process state

3. run arbitary commands, either builtin (echo) or external (ls). External commands require a new process and inherit their process state (descriptor table, where stdout and stdin are conected to) from the parent shell.

4. restore the global process state

5. close the file

If you understand that, it might be clear why the file test.txt is opened before sleep. There's really no other way it can work, given the fact that you can execute arbitrary commands inside the redirect.

I address some related things about redirects here: "Avoid Directly Manipulating File Descriptors in Shell"

http://www.oilshell.org/blog/2017/08/12.html

-----

The more unintuitive thing about shell is that what you wrote is technically better as:

{ sleep 5 && echo hello; } > test.txt

() doesn't mean "grouping" like in other languages, it means subshell. {} means grouping, and it has an odd way of parsing, where ; is required before }, but it isn't required before ). This is because () are operators and {} aren't.

I wrote about this here, "the subshell construct () is confused with the grouping construct { }":

http://www.oilshell.org/blog/2017/02/06.html

-----

EDIT: I will say that I was very confused by the syntax of > and < when I started learning shell. It does seem like ">" means "this goes into that". In fact I think I internalized that from MS-DOS.

But that doesn't explain what these mean, and why they are equivalent:

tac >out.txt <in.txt
tac <in.txt >out.txt

They are best read as prefix operators that modify the state of the process invocation.

What's even more confusing is that you can do:

tac 1>out.txt 0<in.txt
tac 0<in.txt 1>out.txt

Then they look like binary operators again. But the descriptor is "stuck on", it's actually part of the operator lexically.

Valid:

tac 1>out.txt 0< in.txt
tac 1> out.txt 0< in.txt

Invalid:

tac 1 >out.txt 0 <in.txt
tac 1 > out.txt 0 < in.txt

In other words, there can't be any space between the LHS file descriptor and the > or <.

The syntax of shell is horrible, and that's something I would like to fix with Oil shell. But I don't see the problem you are pointing out.
Sprint and T-Mobile could merge in late October
No, but in order to get access to the Fed, the bank link systems and so on and so forth, they need to get government approval.

In order to be bailed out, which is a necessity, they even need contacts as high up as the president.

And even that is ignoring the long history of the government making specific laws specifically to benefit or destroy a single bank.

Nope, no government role here at all. This division simply results in privatizing the profits, nationalizing the losses in trade for having politicians name the owners.

it is if you want to be a reserve bank of course, which is why anyone wants to have a bank in the first place.
I mined a little in the early days, but it kept my CPU pinned into the red and frankly all the people online patting themselves on the back on the size of their mining operation were offputting. I'm interested in cryptocurrencies because of their potential to liberate the mass of people from financial bullying by governments and corporations, not as a speculative vehicle to easy riches.

This will seem pointlessly ideological to most people, but I'm struck by the fact that the bitcoin blockchain is held up as 'proof of work.' There's no work involved besides that to understand the system initially and any code contributions made to the source tree. The actual calculation is carried out by machine. So mining is basically a game for capitalists to invest in industrial hash table production. People who learn about it later and comprehend it in full but don't have any large sums of capital to invest in mining equipment or as a speculative investment don't really derive much benefit from it.

Don't get the idea that I consider it a bad thing because of this - its mere existence speaks to the fact that we've run out of accessible natural frontiers where the curious might stumble upon a fortune, and so we are forced to invent them.
It's not the temperature that is the problem (at least not until you get into copper or steel).

The problem is that molten metal is a liquid. When you melt a filament, the metal will flow away into the thing you are printing, and then keep flowing until it cools down. Extrusion printers can only work with viscous fluids that must be pushed out of the printing head and will stay in place once deposed at the working piece.
