We have a Buffalo AirStation WHR-HP-G300N as the main router. We also have an Asus RT-N53 router located one floor higher. I've set the Asus router to act as a repeater for the Buffalo. There is a problem with it though. My table isn't taking any benefit due to the repeater router. My phone gets a great signal though. Well, it gets it notwithstanding the extra router.   The Buffalo router is running DD-WRT and Asus is running on stock firmware.   The Asus router doesn't seem to be able to act only as a repeater device since it has to broadcast it's own SSID for both 2.4 GHz and 5 GHz frequencies. By the way, the tablet gets an excellent signal when connected to the SSID broadcasted by the Asus router.
If I use  two different router in the same network while both are running in the default router mode then we can access the setup page or setup interface from browser just by IP address of corresponding router. But when I use one of the router as repeater then I can only enter the setup page of the router which is running in router mode. Why router's setup page cannot be accessed when using the router as repeater? Now how can I change the settings of the router in repeater mode? The only way is to reset router with the hardware key then setup again.
Probability to obtain more than X with 3 dice. Variance of a bounded random variable Suppose that a random variable has a lower and an upper bound [0,1]. How to compute the variance of such a variable? Truncated 200GB table but disk space not released I have only 2GB left, so I need to remove this history table. This table now is empty but the database disk space not released. And the database file is 320GB. pyvenv vs venv vs python-virtualenv vs virtualenv and python 3 malikarumi@Tetouan2:~$ pip install virtualenv     Collecting virtualenv     Downloading virtualenv-12.0.7-py2.py3-none-any.whl (1.8MB)     100% |################################| 1.8MB 330kB/s   malikarumi@Tetouan2:~$ pip freeze     (a lot of stuff, but not virtualenv)  malikarumi@Tetouan2:~$ virtualenv testvenv1     The program 'virtualenv' is currently not installed. You can install it by typing:     sudo apt-get install python-virtualenv   What is going on here? is python-virtualenv == pyvenv? Isn't that still broken? Does original virtualenv still work with python? if venv (too many name variations!!!) is part of the standard library, , why am I being told to install it?  And when I did try to install it, I got:  malikarumi@Tetouan2:~$ sudo apt-get install python-virtualenv     Reading package lists...

Setting up python3-pip (1.5.4-1) ...   And I wasn't sure if the extra packages would overwrite them or go onto python 2.7.  I read that python 3 is supposed to be the default going forward. Since both 2.7 and 3.4 are there, and have separate commands, how do I not only make sure Python 3 is my default, but that anything I install goes there and is used by it instead of 2.7?   BTW, I tried sudo apt-get python3-virtualenv and got: E: Unable to locate package python3-virtualenv How can I change PulseAudio port priorities? I list sources and sinks as follows:  pactl list sources pactl list sinks   The output I get is:  ...

Note that I am not looking to set a default source and sink or to delete unwanted sources or sinks, I just want to be able to assign them different priorities. Long-distance Mind Trick In the Star Wars universe, could a Jedi Mind Trick be performed over the telephone?   For instance, could Yoda have called up the Imperial embassy on Dagobah and mind tricked whoever answered into getting him in touch with Palpatine? (I know there's no embassy or telephones on Dagobah, but serious question nonetheless.)   To clarify, are long distance mind tricks not only possible but would being in communication with another person, through telecommunication, allow a force user to better perform the action? When doing a clean re-installation of El Capitan (highest supported version) from a bootable USB on an older Mac (MBP, 15-inch, Late 2008), I get this error:  An unexpected error occured while signing in.

Some movies show it as the body exploding, imploding or even freezing solid.   I know space is essentially a vacuum with 0 pressure and the dispersion of energy makes it very cold.

How do I solve that? I'm on Ubuntu 14.04 (upgraded from 13.10) How to prove that $E[Y]=E[E[E[Y|X_1, X_2]]]$ ?  PS. I don't see how $E[E(Y|X_{1},X_{2})|X_{1}]=Y[Y|X_{1}]$ and $E[Y]=E[E(Y|X_{1})]$ can be used here. But it feels close. Please help, I'm stuck PPS. Thanks @Deep North. Let's consider the case when X1 is independent of X2 Suppose I sold an option on stock X, with strike price Y, and expiry date Z. Suppose I later buy an option on the same stock, with the same strike price, and the same expiry date. Do these two positions cancel out each other (i.e. both contracts cease to exist anywhere), or will I end up with two separate contracts?  Is it the same with the reverse situation? e.g. I bought an option on stock A, with strike price B, and expiry date C. If I later sell an option on the same stock, with the same strike price and expiry date, will I end up with two contracts (one long position, one short position)? How to save animation as a video format I am basically trying to make an intro for my youtube channel. I am sort of familiar with the program because I was playing around with it for a long time, getting the basics of it. With the help of youtube videos I am basically done with my project. I put my name in it and everything. I just need to know how to save the animation onto my desktop as a file that I could open and would be in a video format. Minecraft Vanilla 1.9 crash with problematic frame ig8icd64.dll I go to the Minecraft menu and click on singleplayer to test out the 1.9 update. I made a new world (no mods), it said downloading terrain and then it crashes every time (I've tried about 20 times now).  Has anyone else experienced similar issues and know what the fix may be?

For example, take the following code:  for(Opportunity o: oppList) {       for(String s : strList) {            // I'd like to set the opportunity field values based on the string             // value that contains the API name of the opportunity field       }  }  So, the variable strList contains the opportunity API field names. I'm trying to clear some fields on the opportunity in a before update trigger, but I have to access the field names dynamically in the strList. Show that the locus formed by z in the equation $z^3 + iz = 1$  never crosses the co-ordinate axes in the Argand plane.

Will I miss anything by watching Dragon Ball Z Kai instead of the other series? I've read that Dragon Ball Z Kai is an HD remaster and recut of Dragon Ball and Dragon Ball Z. However, Kai has  while Dragon Ball has  and Z has .  If I watch only Dragon Ball Z Kai, do I miss anything I would get by watching the other two series? And is anything censored in Kai that is not censored in the others? How can I filter items with a certain enchantement? Story identification: Old man has hacker neighbor who mysteriously dies Does anyone know this story? It was a novelette published with another one (I don't remember what it was) in . The premise was that the narrator is an old man whose neighbor, a hacker, dies under mysterious circumstances. A younger woman who is an expert in computer security is hired by the police to investigate what happened, and she has a fling with the narrator. After a while she dies as well, and the narrator realizes that it is an evil force that comes through electric lines is responsible for the killings. The title has interesting formatting in that it ends with a square (much like a command prompt cursor: [_] ) Comma use with nonessential appositives Sorry, I do not know the language terminology. Is this a case of nonessential appositive?  Which of the following sentence has a correct comma use?
