Since, in Avengers: Age of Ultron,       Ultron is in the internet, and all files, and pretty much everything connected to a computer (think Cylons),    how does Tony communicate with Veronica without Ultron stopping him?
In Avengers: Age of Ultron movie,      Ultron infected tech of Avengers Tower just after his birth. It means he is capable of infecting tech. Also, if this wasn't the case, he could never be able to create his drones.   Just after its birth,      He escaped using the Internet and infected digital devices across the entire planet. Again, awesome capability (think Skynet).   We also saw that      Iron Man's armor was connected to the Internet. He googled for the keyword "Hulk" during flight just before he deployed Veronica.   Then, why did Ultron let Iron Man win the fight? Why didn't he simply hack Iron Man's armor to use him as own drone?
Trying to run a Ubuntu server for the first time... But everything is in a terminal. Is there a way to switch to a GUI? Examples of bijective map from $\mathbb{R}^3\rightarrow \mathbb{R}$ Today while troubleshooting a service broker problem, I discovered that the database owner was the Windows login of an employee who had left the company. His login had been removed and thus the query notifications were failing.   Supposedly the best practice for dealing with this is to make 'sa' the database owner. We changed it and that cleared out the queue.   My (very elementary) question: what is the database owner and what is its purpose? Panasonic Lumix G 25mm f/1.7 ASPH vs Olympus M. Zuiko 25mm f/1.8 Cannot make a static reference to the non-static method Canned reasons for up/down vote (w/ example of how it would work) I'm annoyed by down voters that don't explain why they down voted a question or an answer. Although, at the same time, I understand that they . I think there is a middle ground, though, where the voter can remain anonymous, while the poster can get aggregated feedback on ways to improve the post.  Rather than having to imagine what it might be like, the current stackoverflow engine can emulate this rather effectively with the use of comments and the up-voting of those comments (essentially saying "I agree"). So I thought I would give it a try. The only difference is that in this testing post, you will always see the list of "canned responses" where as in the complete version, it will most likely be hidden in a popup (e.g. when you hover over the score of an answer/question). To try it out, simply up or down vote this question (or one of its answers), and press the up arrow next to the comment which best describes why are voting that way. For example, if you hate this idea, give this a down vote, and then press the up arrow near -1: I don't like this idea.  In addition to retaining anonymity, this will also save time for the voter so that they don't need to write out the comment. This wouldn't be required, obviously, and there could be a default option selected don't leave a reason. In addition, there could be a custom option which allows you type exactly why you are down-voting this way. Depending on the final implementation, this could either simply be converted to a comment automatically prefixed with -1:  or +1:; or, to retain anonymity, it would be added to this same list that shows the canned responses and how many users have voted that way.  Here are some ideas for the canned responses:  Question:   +1: Well formatted and thought out question. -1: It doesn't seem like enough time was spent trying to solve this issue on your own. -1: I don't like this idea. (Could be especially useful on meta.stackoverflow.com feature-request.) -1: No prior research/work. (Idea from .) -1: Poor question. Please see . -1: Doesn't contain code. (This would be useful on stackoverflow.com. Idea from )   Answer:   +1: Concise. +1: Insightful. +1: Worked for me. -1: It's wrong. -1: Confusing. -1: Encouraging bad behavior (e.g. answering a question that shouldn't have been asked; see ).   I made this a community-wiki since there will probably be testing of up/down votes. Several of these canned responses have been taken from . This same idea was also . In SQL Server, how do I "floor" a DATETIME to the second/minute/hour/day/year?  Let's say that I have a date of 2008-09-17 12:56:53.430, then the output of flooring should be:   Year:  2008-01-01 00:00:00.000 Month: 2008-09-01 00:00:00.000 Day: 2008-09-17 00:00:00.000 Hour: 2008-09-17 12:00:00.000 Minute: 2008-09-17 12:56:00.000 Second: 2008-09-17 12:56:53.000 I was coding a physics simulation, and noticed that I was using discrete time. That is, there was an update mechanism advancing the simulation for a fixed amount of time repeatedly, emulating a changing system.  I though that was interesting, and now believe the real world must behave just like my program does. It is actually advancing forward in tiny but discrete time intervals? Getting the default text editor used in system I have used select-editor and I note that I am using /usr/bin/nano. Is this the default text editor I am using?  When I open text files, It opens with gedit  What command in terminal must be specified to get the default text editor that I am using, and have it returned to e in terminal? How to copy a file to multiple directories using the gnu cp command Evaluating the sum $\sum_{n=1}^{\infty}\dfrac{(-1)^{n}}{n^{2}}$ I am tasked to evaluate the sum  $$\sum_{n=1}^{\infty}\dfrac{(-1)^{n}}{n^{2}}$$ Using contour integration. This is what I've done so far.   Let $C_{N}$ be the square defined by the lines $x=\pm(N+\tfrac{1}{2})\pi$ and $y=\pm(N+\tfrac{1}{2})\pi$. Let $f=\tfrac{1}{z^{2}\sin(z)}$. I was able to prove that  $$\int_{C_{N}}\dfrac{1}{z^{2}\sin(z)}dz=2\pi i\left[\dfrac{1}{6}+2\sum_{n=1}^{N}\dfrac{(-1)^{n}}{\pi^{2}n^{2}} \right]. $$  By Cauchy's residue theorem. So now if I could prove that he integral converges to zero then I would be done. The problem is that I can't seem to get an upper bound on the integral. I've having trouble with the fact that $|f|$ is unbounded within $C_{N}$ so ML inequality doesn't help me. Any hints would be great. Thanks. is it safe to keep database connections open for long time I have a .net client application which is connected to a remote database. Is it safe to keep a single connection open for the lifetime of the client (hours)? Does the answer hold if I have multiple (10 or 100) clients running? I've read through the elementary proof of why there exists a solution $x$ to $x^2\equiv -1\pmod p$ iff $p\equiv 1 \pmod 4$ for $p$ an odd prime. Is there a group theory generalization for this fact as well? I'm trying to find a way to automatically clean/delete the temporary files from C:\Documents and Settings\user\Local Settings\Temp\ at shutdown/boot on my Windows XP Professional x64 SP2 machine.  The main reason for this is to clean Local Settings/Temp to remove old junk automatically. (I had thought I had this covered through Firefox settings, but I was only clearing temporary Internet files). Currently, there's around 3&nbsp;GB of temporary files, and I'd like to prevent this build up without having to remember to do anything on my part.  I have already looked at using  (explained in Super User question ), but it doesn't seem to touch that directory.  I'm aware of programs such as , but I would ideally like to use a solution that doesn't require additional software (so, I expect, something using a scheduled BAT/CMD script would be what I'm looking for).  One of the potential issues, I believe, is that there may be legitimate files in the Temp folder that may be needed on the next boot (for software installations or updates, for example) and the perfect solution would be able to distinguish those and leave them until they weren't needed (Note: I realise this perfect solution may not be reasonably possible).  I've already set up Disk Cleaner on a shutdown script, but when cleaning temporary files, Disk Cleaner doesn't clean this particular directory, and so I'm looking for alternative options (see Super User question  for a little more detail).  So, what are my options for automatically deleting the temp files from C:\Documents and Settings\user\Local Settings\Temp? Does Devil's Fruit power gained depend on how much of it is eaten? Luffy accidentally ate the Gomu-Gomu (Rubber-Rubber) fruit, but was interrupted by Shanks after a few bites. It was too late and Luffy got the Devil's Fruit powers anyway. If he had instead eaten the whole of it, would he have got even more power from the fruit? "Welcome to emergency mode!"

Photoshop layers into SVG paths interpreting scatter plots I have plotted my predictors versus my response variable in order to be able to fit a good Poisson model to my data.

I am planning to install Ubuntu on it. My computer had 4 partitions: 240GB, 230GB, 230GB, and 230GB, and I changed this to 5 partitions: 243GB, 230GB, 230GB, 150GB, and 80GB. I installed Ubuntu 12.04 to the 80GB partition through a USB flash drive. It installed fine, however the problem is during the Boot option in Windows Boot Manager. When I choose Ubuntu, this what is displayed:  Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:   1. Insert your Windows installation disc and restart your computer.   2. Choose your language settings, and then click "Next,"   3. Click "Repair your computer." If you don't have this disc, contact your system administrator or computer manufacturer for assistance.    File: \ubuntu\winboot\wubildr.mbr   Status: 0xc000000e   Info: The selected entry could not be loaded because the application is missing or corrupt.   I tried to change the boot option for the OS and made Ubuntu as my first option. It worked, however Windows 7 does not show up in GRUB. In this fear I did the following:     Restarted my PC changed boot option 1 to Windows.   Formatted the drive to which Ubuntu was installed (80GB one) through Windows.   Restarted again.     The problem persists. Windows Boot Manager still shows Ubuntu, and when I choose this it gives two lines one like: grub rescue&gt;, but my Windows 7 is working perfectly fine.  Now I want a solution to remove Ubuntu from the Windows boot option and reinstall completely. Transitivity check vs. Transitive Closure Is checking transitivity of a digraph not easier than (in terms of asymptotic complexity) taking the transitive closure of the digraph? Do we know any lower bound better than $\Omega(n^2)$ to determine if a digraph is transitive or not?
