If you read the article (even the summary) you can see this isn't about tricking an admin into running a script. This is about a script already set to say, list a set of directories and do something per directory, but if a user names a directory FOO&BAR the script will interpret BAR as a command instead of input.
If a normal user has read access to a maintenance script to know that this is possible, you've already failed. If your maintenance script doesn't enclose paths and variables containing them with quotation marks, you've already failed. There's a reason MS isn't going to patch it - the problem is in your scripts.
Except you can't equate those measurements. You can calculate the length of the two sticks stacked end-to-end as 1+1=2. You can measure it as 3. You can't equate those separate measurements because of the precision (and accuracy) issues inherent with measuring shit. You don't equate data to data for this very reason.
If you know your upper and lower bounds then you absolutely should use them throughout the use of the data, as you showed with 1±½ + 1±½ = 2±1 .
To be fair, almost no consumers have any use for double. And commercial entities who do usually don't mind the extra zero at the end of GPU's cost, because to them, that's just expenses to be written off on their taxes.
Protip: Make $X in profit, owe some fraction $x in taxes. Write off some amount $Y, owe (x/X) * (X-Y) in taxes. x - (x/X) * (X-Y) = x - xX/X + xY/X = xY/X savings from writeoffs (assuming X isn't 0 - you had a profit, and assuming the writeoffs don't cross brackets).
You only get a fraction of a writeoff as a reduction in your taxes. You can't make huge purchases and write them off as if they were free.
Thats true though. Using nearest integer rounding, 1.4 can be accurately represented as one and produce a sum of 2.8, which can be represented by three.
In other words, 1+1=3 for sufficiently large values of 1.
That would be 1.4 + 1.4 = 2.8. 2.8 could be then rounded to 3, at which point you could say 1.4 + 1.4 ~= 3, Anything beyond that, though, is horseshit.
Who gives a shit about during the flight? What happens when they show symptoms 6 days after landing, after traipsing around a major city for nearly a week?
Now you have to find everyone else who was on the plane and monitor them for symptoms
And, dear God, that's impossible. There is after, no list of everyone who was on that plane. No, no such records of such information exist...
Good luck rounding up all those people, all the people they may have had contact with, etc. Hell, even when someone with ebola goes to the hospital showing symptoms of ebola they send him home. When they go to collect and quarantine that person they don't even have proper gear. When they go to cleanup the scene they don't follow any sort of procedure.
And on the flipside, Wednesday's scare on the plane shits the bed. If it's not very contagious, why do you need to hold everyone on the plane for hours and send in a crew with protective suits (which weren't even worn properly!)? Ebola is a big fucking deal and we do not have a handle on it. They're doublespeaking quite loudly - they downplay the situation and tell us not to panic, assuring us that they have it under control. Yet the moment we have a real incident we see that they absolutely do not have a handle on any of it, and when we have a fake incident the response is all theater.
Can officials increase public vigilance about the deadly Ebola virus without inciting a panic?
No.
Some officials have a vested interest in intentionally inciting a panic. The fox is already guarding the henhouse, the REAL question is: How much of a panic will officials incite while increasing public vigilance.
Most officials will always have a vested interested in lying about it, regardless. If Ebola is a big threat, they can prepare themselves while keeping the public blissfully unaware, helping to ensure their survival. If Ebola is not a big threat, they can whip up a managed amount of fear in order to secure more funding, feel powerful, have fun dicking around with their toys, etc.
Splitting because Slashdot's "lameness" filter triggers primarily on length.
If you receive any meat-space harassment or threats, or if your doxxed beyond name, address, phone number, and place of work (all of these are essentially public information that anyone can get), contact the police. Not the media. Not Twitter. Not Facebook. The police.
TL;DR: Welcome to the internet. Don't feed the trolls.
Oh, and as a preemptive response to the inevitable "victim blaming" accusations, I'll point out the difference between blame and responsibility. If I get hit by a car when using a crosswalk, the blame will likely fall on the driver, though the ultimate responsibility falls on me to be safe when crossing - look both ways, wait for the walk signal, wear bright or reflective clothing at night, not linger in the street to pick up a penny, etc. We accept risk management as a part of everyday life. It's your own responsibility to reasonably minimize the risk to your own life and property. None of this affects where the blame falls in any given situation, be it online or offline.

They only attack these things because of the reaction it will get.
The proper way to deal with trolls is to: Ignore the trolls. Prevent the trolling by not censoring/arguing with angry dissenters. Prevent the angry dissent by not making yourself a target for angry dissent by posting bullshit people will call you out on.
Now, it's perfectly within your right to post bullshit. However, you should expect angry dissent as a reaction. It's also very possible to post non-bullshit and still get angry dissent through no fault of your own. In both cases, the key is your reaction. Never try to censor the dissenters, and never get in a flame war with them. If you really must respond, do so carefully, without being a bigot (people have different opinions and dismissing someone else's without fair consideration because you've already form your own is the definition of "bigotry"). Remember that if your response is seen as emotional in anyway, or if you seem personally upset about the thing you're responding to, it will be entertaining to potential trolls. If you've gone ahead and made yourself a target and you're actively being trolled, just stop posting. Ignore any and all threats of violence online - they're about as real as the kids in IRC who threaten to pwn ur box because you beat them in Quake.
It's harassment, and it's harassment that would have been targeted toward anyone espousing the same views, and it's wrong. But it's not a threat.
People need to learn that trolling is a natural response on the internet because of the size of the audience and the relative safety of being able to say what you want without consequence. These "victims", female or otherwise, are causing these reactions (often intentionally in order to get further attention) by publicly espousing a view that many recognize as fucking bullshit. In meat space, this often gets no outward reaction. People may think you're a fucking idiot and may hate you, but they won't outwardly say it in a place where you can see it. On the internet, with an expanded audience and relative safety, the odds of one person calling you out on your bullshit increases greatly. Once that ice is broken, others feel validated, and will join in to express their own views. This is all fine. If you can't handle disagreement, often angry disagreement, don't have a forum / comments section on the same site you post the shit people will disagree with.
The trigger that escalates it from angry dissent to trolling is the reaction. The instant you try to argue with or censor the angry posters you unleash the trolls. Whether you're right, wrong, or winning or losing the argument doesn't matter. When you start an argument online with an angry poster you're just inciting them to continue as well as providing entertainment for those watching. This entertainment feeds the "for the lulz" mentality of any potential trolls watching it, and shit escalates.
When a troll targets someone, they will always attack what they perceive as vulnerable. Race, religion, gender, sexuality, physical appearance etc. are all bright red targets in the eyes of a troll because the troll knows they can get an emotional response by targeting those things. Emotional responses extend the flame war, providing more lulz.
Your numbers reflect my experience as well except for 802.11ac.
I am getting between 300 to 400 mbps real world throughput depending on how far the wifi device is from the router. That's with connection rates between 500 and 1300 mbps - the later achieved with an Asus PCIE 802.11ac NIC.
IMO, 802.11ac is a huge advance over 802.11n.
Just wait until your neighbors pick up an ac router.
Real world tests of 802.11n/ac show that they deliver much closer to the headline rate than any of the older protocols. 802.11n can actually go up to 450Mbps with an actual local transfer rate of around 350, while 802.11ac wave 1 can get even closer to the headline rate. Depending on the transfer direction good WiFi can flood a 100mbit duplex link.
The key issue is with spectrum efficiency is utilisation. Those numbers are 1 device and 1 radio. As soon as you add another device, you're sharing that spectrum (until wave 2 with MU-MIMO complicates this). You also get more signalling overhead and collision retries with each ssid, ap, client in the same audible space.
I've run both n and ac over a dozen different networks and I the only time I can ever get anywhere NEAR rated speeds is if the AP and the client are in a basement. Wifi degrades the instant you bring it out of a testing cave, and it turns to absolute shit the instant your neighbor fires up his own radio of the same class. I don't give a flying FUCK about theoretical rates in a best-case scenario, I care about how it's going to work in a typical deployment. Wifi is, and continues to be, horribly designed with regards to channel spacing. And the "solutions" to that have been higher frequency and lower power, trading range for speed.
Can we take Carl off the pedestal yet? I know, it's hard to let go of childhood heroes, but almost all of his "contributions" to science were of a metaphysical nature, which is to say, not really scientific contributions at all. These writings included.
The problem with FTP is that it can be a PITA to make sure it is measure memory to memory speeds and not disk to disk speeds. Sometimes you can write files to/dev/null and read from/dev/zero (and then manually abort it since/dev/zero is endless).
If your downlink out paces your disk writes, it's time to upgrade.
Not really fair to immediately disregard the quality of the WiFi connection. It could be well in excess of the ISP connection.
Have you ever even used wifi? 802.11b = 11 mbps, real world throughput = ~6 mbps. 802.11g = 54 mbps, real world throughput = ~20 mbps. 802.11n = 300 mbps, real world throughput = ~60 mbps. 802.11ac = 1500 mbps, real world throughput = ~160 mbps.
Suspension of Disbelief: Spiderman exists and has super powers and is the only one capable of stopping The Lizard.
Terrible Writing: Some guy in New York totally knows all the crane operators in New York, knows the location of Spiderman as well as his destination, and at a moments notice is able get all his crane operator buddies to line up a dozen or more cranes on building tops along a single street and extend them so that Spiderman may web sling from them.
Hollywood: The cops hate Spiderman and want to capture him, but after seeing The Lizard they have a change of heart and love Spiderman. To show their newfound love for their new favorite superhero, a police helicopter hovering just above the roof Spiderman is on shines its spotlight onto the cranes that were lined up for him. Showing Spiderman the way to swing, swing, swing, swing, swing toward the Lizard Man is a nice gesture, but it would have been faster, easier, less dangerous, and a hell of a lot more practical to just give him a ride in the fucking helicopter.
You get the executable when you get the SDK. It's not hard to monitor HID, lol. None of this is hidden, buried, or secret. It's just not published. Anyone who has the SDK can easily do what you did. Actually, maybe I should rephrase that to "any developer who has the SDK", since these seems to be a lot of people who have the SDK who are just people buying into the hype and treating it as an early product release, as opposed to being developers intending to make shit.
You're acting as if you cracked some shit open on the level of finding a exploit to unlock / root a smartphone, or running homebrew / "backups" a video game console. To use a car analogy, you looked under the hood and counted the cylinders on the engine.
But please, tell us more about that book you're writing! We're all so excited to give you money to read more of your insights.
