When we have completed a todo task we "cross it" to mark it done. i would say the x to close is intended to represent a "crossing out" not the letter x. It is pressed to signify a task has been completed.
The Atari Gem thing is not an X, it's actually supposed to be a gem. It's just confusing because of the low-res image. Take a look at

Mono performs "fine". That is, I've never really isolated Mono as the cause of performance issues. I'm running it in telecom applications, handling billions of transactions a week. Years ago I compared things, and the CLR was usually better. But generally speaking, the approach in algorithms/approaches is going to dominate the runtime.

The exception is when you're dealing with a very high transaction rate (say, doing 100K msg/sec, non-trivial processing per message, in a single process). Then the GC overhead is something to be aware of, and you'll go to extreme lengths just to remove a handful of allocations for each message. At that point, manual memory management (either via hacking up the runtime with unsafe code, allocating large arrays of structs, or using unmanaged code) is the right path. But from light reading, it seems the same is true in Java or other GC languages, so no difference for Mono there.

So the alternative is C, usually, which has its own set of tradeoffs. Rust looks far more promising, but in general, Mono's performance is just good enough that I'm more likely to keep my nice F# code and add a few boxes. Unless you're in a high-performance arena, and you'd know if you are, this likely holds true for your business.

Edit: Also, I'll note we're using Mono 2.10. So updating to 3 should get us the new GC which may make a difference, as well as allow LLVM code, which should help significantly for server apps.

RiscOS had the x as well in the late 1980s

edit - Here's Arthur, the precursor to RiscOS in ~ 1986 - http://www.rougol.jellybaby.net/meetings/2012/PaulFellows/10... - It has nice x icons.
Atari ST users seemed to see it as an X -- so whether or not it was intentional on the part of the designer, it's not that hard to see how one of these users could have then translated that misconception to the Windows 95 GUI. It's all about perception...
In this early demo (Codename: Chicago), the minimize and maximize buttons have been redesigned, but the close button remains the same, and to the left as before.

I wonder where the author got the idea that the [-] button at the top-left was a close icon. It was the "Control Box", a menu icon. AFAIK it's still there, just invisible -- hit alt+space to open it.

Disclaimer: I'm currently unable to test that.
I misinterpreted the title as "X Windows consortium to close."
Wow that was a bit extreme heh. But I think that role of technology vs role of business model is what makes a hackathon different from, say, startup weekend. And again, as the author pointed out, we don't need to get the first price to enjoy the 'high' and fun of a hackathon. Onward!
Perhaps it's not an icon, and was meant to indicate eXit. I know must use 'q' for quit, but I've seen a few programs that use 'x'
Interestingly the positioning of the two matches the common use of the nintendo buttons, A for confirm and B for cancel. The western Playstation games are really the exception to the rule.
Moreso I think what throws me is that in your example, the FCC cubes are tilted. (i.e. if you build a FCC stack starting with a grid of squares rather than triangles, it's much more difficult to visualize where the closely-packed triangles lay.)

While this may come across as sour grapes, I find generally I need less IDE help in F#, since I'm not typing as much boilerplate. For instance, almost all type annotations are inferred (20:1 in my own empirical study), so there's a ton of code I simply don't need to type.

In general, I find writing in C#, I'm going to need 50-200% more code for "business logic" type code that doesn't particularly benefit from F#. That is, using F# as a better C#. And this is after C# hacked in async - before that, there's no comparison if you need async style code.

If C# added pattern matching, tuples, active patterns, type inference, everything-as-an-expression, nesting, more comprehensions, etc. etc., then yes, C# would be competitive. And with all the resources C# gets, the IDE would be far better than F#, sure.
That's not GEMTOS, that's GEM for DOS... big difference...

To be fair, n may be arbitrarily large, hence the undecidability of logics in general. (Not disagreeing with you, just clarifying.)
The reason why it's so expensive for startups to even consider defending themselves is because attorney fees are supra-competitive and corporations cannot represent themselves in court pro se according to Local Rules, such as Civil Local Rule 3-9(b) in the Northern District of California. Whether through (absurd) precedent or rules codifying that precedent, it's been that way for 200 years.

However, it shouldn't be that way anymore--not after Citizens United. I'm fighting a lawsuit about this issue right now, and if I win (however unlikely), corporations will be able to represent themselves against patent trolls.

Is it difficult, confusing and complex work? Yes. Is it any harder than programming, or anything else a serious startup would do? Not really. And it beats paying a law firm six or seven figures.

The case is:

I entirely agree, for most situations the trade off is in favor of high-level languages like Python. The scale tips even further in favor of CPython when you start using C extensions like Numpy. All of the benefits of Python, with speed approaching that of pure C (there's some overhead when calling from Python). For use-cases like web applications, the language is almost never the bottleneck anyways. Network latency and database queries usually eat up far more time than the glue code holding it all together. And this isn't even touching on the security benefits of memory safe languages.

What in particular do you mean by this? "Protected" accessibility, automatic mutual recursion for everything, nested classes -- and a few other edges? Is that enough to say C#'s a "stronger OO" language? Perhaps strictly speaking, as in, it has those few features more. But in practise?

But then what of C#, which lacks object expressions? Which forces you to declare a type, often an interface, just to implement a member or two?
The problem with making the opposing red end sooner ("oncoming traffic has longer green," as the signs say) is that the opposing permissive left turns that haven't cleared by the end of the yellow are then caught in the intersection with their signal red and yours still green. The problem is called the "yellow trap" (http://en.wikipedia.org/wiki/Yellow_trap), and some states, including California, outlaw the practice because it is too dangerous.

I'm completely with you about wanting everything demand-actuated to be very responsive, though. Traffic signals are all engineering with no user interface design at all.

While switching to glass sounds like a good option, I have to point out that glass breaks. How does the known risk of glass breaking, and cutting children compare to the theoretical risk of these plastic containers? Or the pain caused by hitting their heads with glass containers?

It seems like Sony, being a Japanese company, originally intended for O to represent yes, and X to represent no. If you look at a lot of early PlayStation games, or most modern games released in Japan, that convention is apparent. The O and X buttons on the PlayStation controller even match the placement of A and B buttons on Nintendo's controllers, providing a clear analogue between the two.

I'd be curious to know what caused that convention to change in the west.
HDMI output would have been the main display improvement but given where a PPU or a VDP sits in these architectures, you could do a lot of fun stuff including running your own CPU core on the FPGA. (Edited - thought there was a wait pin from the PPU to the CPU but looks like it's an interrupt)
I'm the author of hexcap(http://www.hexcap.org), an ncurses libpcap file editor and packet generator. I've also written many Scapy applications like this one(https://github.com/smutt/mcastClients). I rewrote the DHCPv4 client in Scapy since the stock one is broken. Also as part of hexcap have made numerous fixes to dpkt. Needless to say, I've done a lot with Python and packets.

If you're interested in writing a TCP/IP stack in Python I would recommend you use Python raw sockets, or possibly dnet[1] or pcapy[2]. The Scapy level of abstraction is too high for your needs.

I agree with other posters who mention buffering in libpcap. Read the man page for pcap_dispatch to get a better idea of how buffering works in libpcap. Also try capturing packets with tcpdump with and without the '-l' switch. You'll see a big difference if your pkts/sec is low.

Don't do arp spoofing. If you're writing a TCP/IP stack then you need to also code up iparp. If you don't want to do that, then use raw sockets and query the kernel's arp cache.

On second thought you really need to use raw sockets if you want this to work. Using anything pcap based will still leave the kernel's TCP/IP stack involved, which is not what you want.

Windows 95 was the first time I remember using it, and I have been using PC's since TRS model 80. It makes sense, X means "stop" in most cases and stop essentially means close or terminate a process / app.

I think it's great that you're here and perfectly okay to mention your degree (in your profile).

However, even if you feel you've been unfairly treated, your own words won't garner you many friends.

If your goal is to counter "antifluoridationists posting blatant misinformation", then you're totally ineffective, possibly even helping them out by making your side look bad.

I'd suggest to conform to the rules (yeah, "guidelines") here at first and find out if it's really so bad.

Or as someone I highly value once said on Usenet: if you want to transcend something, you've got to show that you're really understanding it, in order to transcend it in a meaningful way. Otherwise people will assume ignorance instead of transcendence.
OTOH his key contribution to special relativity, so I gather, was the axiomatic approach. Others like Lorentz had worked out most of the formulas already by finding some tractable-enough assumptions about electrons and atoms; Einstein went back to the style of Euclid and Archimedes: what if we postulate a few simple laws and draw out consequences?

Back to the article's topic, Einstein wrote that Euclid was a revelation to him when he was 11 or so. (I forget exactly; it was in the intro to his book Relativity.)
This sounds like pseudoscience. Your search results also look like either pseudoscience (a "Vitamin C foundation" with 90s style marquee text and Google hit counts for "vitamin c ebola" to bolster its case), or real science that just happens to tangentially mention vitamin C (such as http://jid.oxfordjournals.org/content/179/Supplement_1/S18.f... on the use of blood transfusion from recovered patients for treating ebola).

You also manage to embed the "no true Scotsman" fallacy into your very short argument; "no viral infection has been demonstrated to be resistant to the proper dosing of vitamin C" is trivially true if you just say that any failed treatment simply wasn't using a "proper dosing of vitamin C".
Well .... I don't know about everyone ....
A route to one of our subdomains was not working at our hosting provider. It affected our application because we relied upon the subdomain as a cache between S3. Pages in the application would fail when cache was reloaded.

Never mind our application, but there are some interesting "what ifs" out there, like if the route for some major players were to suddenly stop working...or, perhaps similar to our app, some minor routes failed but major sites relied upon them.
I actually distinctly remember getting a copy of Metal Gear Solid 2 and being confused why I couldn't start the game. Hitting any button on the splash screen would take you to the menu, and then hitting X from there would take you back to the splash screen. Having primarily played western games up to that point, it didn't even occur to me that another button could be used for 'confirm'.
I thought the popular rumor was this was to help people with Nintendo 64 muscle memory, where the X corresponded (loosely) with where the A button was positioned, and the O corresponded to where the B was positioned.
I was looking at the wrong end of the window, to boot.

Pellagra is a vitamin B deficiency. It has nothing to do with EFA.

You could at least look up the first line of a Wikipedia article? Tryptophan is an essential amino acid.

It can be caused by decreased intake of niacin or tryptophan,[1] and possibly by excessive intake of leucine.

Anyway, in the absence of any sources there's not much I can gain from this discussion, unfortunately.
It's certainly amusing to imagine the argument, "If a disease has not been cured using vitamin C, that simply means they were not given ENOUGH VITAMIN C whips out wheelbarrow of oranges"
Primary sources are always useful, but so is some context from the writer. Reading the patent and the recent SCOTUS opinion, Alice v Cls Bank, it definitely looks to be invalid in the context of software implementation. I wouldn't call the writer "disingenuous." It would be difficult to argue for fee shifting as an exceptional case, because there has been only a few recent decisions and not consistent precedent yet.
Note that it was already known that FCC was the best periodic packing (740‰ density); this was proven by Gauss. What was not known was whether there was a more efficient aperiodic packing, such as those described in http://en.wikipedia.org/wiki/Quasicrystal.

F# will almost definitively help any C# code. Even if you use F# as a "better C#" you'll see improvements. Just removing excessive type annotations is a nice step up in clarity.

F#'s benefit will come as a bunch of tiny improvements, "programming in the small" as they call it. For instance:

let xs = [ while r.Read() do yield r.GetInt 0 ]

In C#, it's:

var xs = new List<int>();
while (r.Read()) { xs.Add(r.GetInt(0)); }

Or:

let f x =
let x = try int s with _ -> -1
x * 3

In C#, it's uglier. First because try... isn't an expression. Second, because you cannot shadow variables by rebinding them, so you always have to keep "old" vars around and in scope, and cannot reuse handy variable names:

int f(string x) {
int x1;
try { x1 = int.Parse(s); }
catch { x1 = -1; }
return x1 * 3;
}

Or:

let x =
use db = new DB()
db.GetX()

In C#, you've got to declare x outside a block:

SomeType x;
using(var db = new DB()) {
x = db.GetX()
}

Which is more annoying than it might seem. How much nicer is it to be able to create a new scope at any point in a function, and return a value out of it cleanly?

These are by no means a complete or even important showcase of C#'s lacking. Just a few quick thoughts off the top of my head. In general, every time I'm writing C# code, I keep realising how things would be much more concise if I was in F#.
It's possible, sadly there is no folklore.org for Nextstep. In the end, both the X and things like context-menus were made ubiquitous by Windows '95.

While some would say the risks of the Facebook study were obvious, Professor Hancock said the researchers did not realize that manipulating the news feed, even modestly, would make some people feel violated.

I have to call bullshit on this. The whole point of the study was to see how their emotional state would be affected. Prior to this, no one would have expected to be "experimented" on while using a consumer web product.
I wonder if this model can work with the criminal justice system as well. Quite often, defendants feel it is better to accept a plea deal even when they have done nothing wrong because the economics of fighting a lawsuit (as well as the outcome in case of a botched up defense) makes it compelling to accept the accept the plea deal. The mechanism is analogous to the patent troll scenario. If law school students can take up these "troll equivalent" cases, they gain valuable experience and defendants get a fair shot.
That list of Math Olympiad top-scorers is interesting. I notice Peter Shor at #3, and Jim Propp ("coupling from the past") at #5. Wow.
It might be because of Sega's consoles, which were more popular in the US than they were in Japan, where Nintendo ruled.

The Genesis' button layout was A,B,C arranged in a diagonal from bottom-left to top-right. A was usually 'accept'. The Dreamcast had a diamond with A at the bottom and B to the right.

Nintendo's Famicom buttons read A,B from right-to-left, and that trend continued with the Super Famicom's diamond, which had A to the right and B at te bottom. The N64 had a weird layout, but again B was to the left of A.

Sony probably focus tested the pad in the US and found that players were more used to Sega's layout.

I have posted this before on HN, but I don't understand how, as lead levels continued to rise, IQs also increased during the 20th century. And someone pointed out in another comment, as blood lead levels have plunged, we should have seen the lost IQ points being recovered. Has there been evidence of a large gain in IQ since blood-lead-levels have dropped?

Wrong. In these cases you want your stack to be as fast as possible. But you're introducing artificial delay on selected keypoints. If your attack code is slow, then you're basically attacking your self. Target is to consume (a lot if possible) more resources on the target side, than you're using on your own side.

You don't have to "call bullshit". The text you quote can be better understood as saying that facebook should have known that if users found out they were being manipulated, they would feel violated. This is indeed what happened.
