How to install Android Studio on Ubuntu?
Can you choose which version of a game to play on Steam? I want to play a game in an older update, but can't see a way to choose a specific version. Is this possible? I have a string "1112224444' it is a telephone number. I want to format as 111-222-4444 before I store it in a file. It is on a datarecord and I would prefer to be able to do this without assigning a new variable.  I was thinking:  String.Format("{0:###-###-####}", i["MyPhone"].ToString() );   but that does not seem to do the trick.  ** UPDATE **  Ok. I went with this solution  Convert.ToInt64(i["Customer Phone"]).ToString("###-###-#### ####")   Now its gets messed up when the extension is less than 4 digits. It will fill in the numbers from the right. so  1112224444 333  becomes  11-221-244 3334   Any ideas? init.m in Autoload directory is not read by parallel kernels in M11.2 Using restroom on airplane while fasten seatbelt light is on? This question about  over on  made me wonder what a passenger is supposed to do when they urgently have to use the restroom while the fasten seat belt light is on. FAA regulations require passengers to obey the seat-belt sign, even if flight attendants do not.  I saw this happen on a flight where an older gentleman asked the flight attendant if he could use the restroom, and she said "not until the light is off". The flight had been free of turbulence for 15 minutes or so by this time, and the flight attendants were walking freely throughout the cabin, collecting post-meal trash, etc. The gentleman who asked to use the restroom appeared to be in quite some discomfort, and practically ran to the restroom when the light went off 10 minutes later.  So what is a passenger supposed to do when he isn't permitted to use the lavatory, when he has to go and can't wait? Just go in their seat?

If my score is good and if I'm applying for an MS program in Europe, can it give me any kind of edge? The university I'm applying to requires GRE scores for certain programs but not the one I'm applying for. And if it won't be advantageous, can it hurt my prospects in anyway?

How is the following classical optics phenomenon explained in quantum electrodynamics?   Reflection and Refraction   Are they simply due to photons being absorbed and re-emitted? How do we get to Snell's law, for example, in that case?  Split by request: See the other part of this question . Defrosting meat/fish in warm water I have found warm water to be a great way to quickly defrost meat and fish as opposed to just letting it sit outside the freezer, which is what my mom does.  But I wonder if there are any negative side effects to the method, as in, for example, compromised taste or compromised food safety.  I do understand that the water shouldn't be too hot as to avoid actually cooking the frozen food. Solve for $x$: $2^x=4x$ Given that $x$ is a positive integer. By using methods of trial and error as well as plotting two lines: $y=2^x$, $y=4x$ on a graph and find their intersection point, we can easily solve for $x$ which is equal to 4. However, I do not know how to solve this using only equation. Can anyone help me? Cannot authenticate without a password Intuition behind why order of a subgroup divides order of a group. Can somebody help me to prove this identity?     $$\prod_{k=1}^{n-1} \left(\;\cos\theta-\cos\frac{k\pi}{n}\;\right) = 2^{1-n}\sin(n\theta)\csc\theta$$   I was thinking of using the properties of the complex numbers and the binomial theorem, because I found this problem in the Complex Variables book from Schaum's, but it did not solve my problem.  Does anyone have an idea?  Thanks in advance! Ring of $\mathbb{Z}_2$-valued functions Let $R =\{f:\{1,2,3,4,\cdots ,10\}\to \mathbb{Z}_2 \}$ be the set of  all $\mathbb{Z}_2$ -valued functions on the set $\{1,2,3......10\}$  of the first ten positive integer. Then $R$ is a commutative ring with point-wise addition and multiplication of functions. Which of the following is true?     1) $R$ has a unique maximal ideal.      2) Every prime ideal of $R$ is also maximal.      3 ) The number of proper ideals of $R$ is $511$.      4 ) Every element of $R$ is idempotent.   R is finite commutative ring so  every prime ideal  is maximlal ideal ,so I think option  2 is true   .But for the other options   I am  helpless  . Unsupervised learning for anomaly detection I've started working on an anomaly detection in Python.  My dataset is a time series one.

The ContextID is more like a product number.  I would like to know which unsupervised learning techniques can be used for this kind of task at hand.  Thanks Joris and Srikant's exchange  got me wondering (again) if my internal explanations for the difference between confidence intervals and credible intervals were the correct ones.  How you would explain the difference? Will getting a Software Testing Certification benefit me in my career? My grandparents bought a flight on United Airlines, as the one and same ticket, from Toronto, to ORD with one 55-minute layover, then to Maui. :     You won’t need to pay extra for airfare if you miss the flight, but on the other hand, you will most likely not be compensated by the airline for the incurred delay. It always depends on the amount of time, the reason for the delay and the airline’s policies. As soon as it’s weather-related, you won’t be getting a penny (and that’s normal: airlines can’t control the weather).    Yet they obviously prefer to avoid such charges from missing the 2nd flight.   Please see the titled question? Would they need to hotfoot or scamper from one gate to another, to not miss the 2nd flight? If yes to 2, can they request an airport electric shuttle cart now, before the flight?
