I'm not much of a networking guru, but I'm needing to conduct an experiment to see why some RSLs are not loading on some client computers when they try to load a swf off of their intranet's server.  I'm tempted to believe this is the result of their inability to access adobe.com to download the RSLs.  However we have seen these same swfs work on other computers that are kept away from the Internet, and my theory here is that this is simply due to the RSLs being cached a while back inside of their Flash Players.  To test the theory, I'm wanting to completely block *.adobe.com from my computer, so as to avoid being able to download RSLs from their website.  Then I want to completely uninstall, then reinstall Flash Player, then load the swf from one of our own servers.  I am NOT able to manipulate hardly any of our own networking at all.  I can use Windows Firewall, but that doesn't appear to be able to block specific sites.  I have tried adding this site to things like the Restricted Zone in IE, but I'm still able to visit the site just fine for some reason.  There is no reason this should be so difficult.  Any ideas?  Thanks!
For privacy and performance reasons, I'd like to prevent my computer from ever communicating with certain Internet hosts. I'd like to do this at the OS level, not through web browser plug-ins (not broad enough), or even through my home router (my laptop travels). I'd prefer to use built-in tools.  I'm running Windows 7 Professional 64-bit. I'm all too familiar with the Windows hosts file - and its limitations. There seems to be some confusion over whether hosts supports wildcards, but my own tests confirm that it does not.  I have experimented with Windows Firewall and the IP Security Policy MMC snap-in. So far as I can tell, both require numeric addresses. I don't want to block specific IP addresses, or ranges of addresses, in part because IP-address-to-hostname mappings can and do change.  Is there any tool in Windows 7 Professional with which I can block (or route to 0.0.0.0) communication with Internet hosts by hostname mask? If not, are there any good, free, third-party tools?
How does ZFC describe addition? Surprisingly, the Wikipedia article on addition doesn't contain the answer. I looked  elsewhere online for it, but didn't find it.   Intuitively, the cardinal of the union of two sets seemed appealing. But that approach doesn't work, given that the union of 2 and 2 is 2. I wondered whether ordered sets might be essential to the answer.   So, how does ZFC describe addition? How can I connect two different DC power sources together? How can I connecting two different DC power sources together? for example 15Vdc(5Amp) with 5Vdc(2Amp). I want to make one DC source (20Vdc,7Amp) by more powerful supplies. Let $A$ be an infinite set. For each $a \in A$, let $x_a$ be a non-negative number. Let the value of the series $\sum_{a \in A} x_a$ be the value of the supremum of its finite partial sums, i.e.:      $$\sum_{a \in A} x_a = \sup_{n \geq 0} \sup_{(a_1, \ldots , a_n) \subset A} \left(x_{a_1} + x_{a_1} + \ldots + x_{a_n}\right)$$   (Supremum is well defined even when its value is infinite)       If $\sum_{a \in A} {x_a}$ is finite, prove that the set $A' = \left\{{a \in A | a &gt; 0}\right\}$   is countable.   My guess is that we have to write $A$ as a union of finitely many sets. How can I efficiently recover a permanently deleted folder at once? What is the speed of sound in space?

Can a mathematically sound prediction interval have a negative lower bound? I have used R to form a 95% prediction interval for the number of endemic species on an island. My lower bound is negative – is that mathematically sound?  In the linear model used in the prediction interval, the data used are:  Area Surface area of island, hectares DiscSC Distance from Santa Cruz, kilometres Elevation Elevation of higher point in metres and it is coded as such:   selected.model &lt;- lm(ES ~ Area + Elevation + DistSC + I(Elevation^2)                      + (Elevation:DistSC) + (A‌​rea:Elevation))    and stepwise regression was performed to find this "best" model   I'm not exactly sure how a prediction interval works. I just want to make sure it is OK. Obviously a negative number of species is incorrect, but I know it takes into account the uncertainty of the mean as well as data scatter. How can I tell whether beetroot is still edible? I have some raw beetroot I bought about a week ago, having stored them at room temperature since. It's the first time I bought it raw, and I'm unsure whether it's still edible.   It is already soft, and when I cut it, it smells... Well, different than I expected. It's not a rotten smell as such, but it's nothing like the sweet beet-rooty smell I know from the pre-packaged, pre-boiled supermarket variety.  How can I tell whether it's still safe to eat? How do I make a Lightning Bow in vanilla Minecraft? I'm trying to make a setup with command blocks that summons lightning at the location of a shot arrow. The setup should recognize the arrow that is shot or the bow that is used by its name or another property, so that lightning only strikes at that specific arrow.   Also, the lightning should only strike once when the arrow hits the ground. I know this is somehow possible with scoreboard, but I'm no good with that. Does anyone know how to make a Lightning Bow in vanilla Minecraft? Proof that two basis of a vector space have the same cardinality in the infinite-dimensional case I am having a difficulty setting up the proof of the fact that two basis of a vector space have the same cardinality for the infinite-dimentional case. In particular, let $V$ be a vector space over a field $K$ and let $\left\{v_i\right\}_{i \in I}$ be a basis where $I$ is infinite countable. Let $\left\{u_j\right\}_{j \in J}$ be another basis. Then $J$ must be infinite countable as well. Any ideas on how to approach the proof? Confusion between register size, address size, data size I started learning about pointers in C++ and I figured I should educate myself a bit on how memory works and is accessed. I read that when we say a processor is 64-bit, it has a 64-bit register and can access 2^64 address locations. I also read that it can fetch 64/8, so 8 bytes of data at a time, but the data bus is not the same thing as the register right? Do they need to be the same size or does that just happen to be the case usually? And is it the size of the register or the data bus size that determines what we refer to it as, such as 32/64-bit? Also is there a difference between register size and address size? CASESAFEID() apex equivalent Is there any function in Apex which could emulate functionality of the  formula function? I'm trying to get 18-char Id variant from the standard one. dpkg exit with error parsing file `/var/lib/dpkg/status`, what to do? I'm running Bash scripting, but sometimes I get confused which of these commands I use belong to who. Sometimes man xxx works, sometimes doesn't, so I use --help or info, mostly one of these works to show description of the command. Can anyone tell me how I would know what command belongs to what? Bash builtin, GNU utility, etc. How do I find playtesters? Obviously the first tester group would be your own group. But beyond that? It would seem to make sense to have at least more than one group test out your game, as different groups want different things and play differently. Fresh eyes find different bugs, etc. etc.  Are there resources out there to help aspiring game designers without a lot of contacts find people willing and eager to test out their game?  Or is this in essence a "" issue?  To clarify my own situation:  I have the mechanics finished. The setting is still under development, but in accordance with the motto "fail faster" I want to go ahead and test the mechanics (in a different setting for now) to see if they work and are fun or if I need to go back to the drawing board. I have a sort-of group, but I don't know them very well and they don't meet often, and so I'm not excited about the prospect of presenting the mechanics to them right now (as I'm sure there are a dozen issues I've overlooked). Also, I'd like to test the game (including the setting, later) on more than one group, as mentioned above. I've put out some feelers among my current friends and acquaintances, but nobody's really been excited about playtesting or even really giving in-depth feedback, and I don't want to be that person who's always shoving their project in your face. I'm willing to run something online as well. I'm also interested in having others run a game without me present, and giving me their feedback.  Also, I'm looking for something of a guide-type answer that might help someone besides just me. How can i find the python triggered by the GUI? I want to fully automatize some of my blender processes, an i run into a lot of problems not finding the correct commands, not using the correct args...  Can i just "see" in a log somewhere what were the commands blender ran ?  To be very precise, i want to load a gltf file, and export it to stl.  No problem through the gui, but i'm stuck with that bit of code :   import bpy import sys import os  file = open(r"C:\Users\theo1\Documents\GitHub\Hackathon2020\map&amp;mapdata\mini.gltf")  bpy.ops.import_scene.gltf(file) bpy.ops.export_mesh.stl(filePath=r"C:\Users\theo1\Documents\GitHub\Hackathon2020\map&amp;mapdata\mini.stl")   Which gives me this :   Traceback (most recent call last):   File "&lt;string&gt;", line 1, in &lt;module&gt;   File "C:\Users\theo1\Desktop\impExp.py", line 7, in &lt;module&gt;     bpy.ops.import_scene.gltf(file)   File "C:\Program Files\Blender Foundation\Blender 2.81\2.81\scripts\modules\bpy\ops.py", line 198, in __call__     C_dict, C_exec, C_undo = BPyOpsSubModOp._parse_args(args)   File "C:\Program Files\Blender Foundation\Blender 2.81\2.81\scripts\modules\bpy\ops.py", line 151, in _parse_args     raise ValueError("1-3 args execution context is supported") ValueError: 1-3 args execution context is supported   thanks. I'm working through a problem regarding expected values in Markov chains, and at some point it says:     Recall from probability that if $X$ is a positive integer valued random variable, then $\mathbb{E}[X] = 1 + \sum^\infty_{k=1}\mathbb{P}(X &gt; k)$.   I know that by definition $\mathbb{E}[X] = \sum_a a\mathbb{P}(X = a)$, but I can't see how the above equality follows from this, nor am I sure if this is how to approach the problem. It's common in C++ to name member variables with some kind of prefix to denote the fact that they're member variables, rather than local variables or parameters. If you've come from an MFC background, you'll probably use m_foo. I've also seen myFoo occasionally.  C# (or possibly just .NET) seems to recommend using just an underscore, as in _foo. Is this allowed by the C++ standard?
