I can't log into any Minecraft servers at all, not even locally hosted ones.   The error code I get is: java.net.UnknownHostException: session.minecraft.net. A tweet from a worker at Mojang told people that you could just flush your DNS, which I did. That didn't quite work, so I'm wondering if there are any other solutions out there?   I'm not quite sure what other information I have to give. I know that it's not just something with me because I know a lot of my friends also get this error once they try to log into a server, so it would be weird if all of our ISPs just cut us off.
I can't play online. I can only play solo. I have bought Minecraft so it should work fine, but, when I try to connect to a server, it says:  Internal client error: java.net.UnknownHostException: session.minecraft.net   I have tried over 20 different servers and it says the same thing for every single one.   Note: These are not Hamachi servers. I'm attempting a direct connection.
using variable length argument in scala Can file uploads time out in PHP? Hi im quite new to PHP, i have created a form for very large csv files to be uploaded to my server. Some one mentioned to me that the browser can time out due to the uploading file being to big, is this true? and if so, can it be prevented?  Thanks for your help! HTML and CSS is not working? I've seen a lot of people talking about FPGA's before and I know that it stands for field-programmable gate array but how does it work and what is the purpose of using an FPGA? What did the general public know about Darth Vader? When Darth Vader first becomes Palpatine's apprentice, very few know of his existence and connection to the Emperor: the members of the Trade Federation (whom he dispatches) and Yoda, Kenobi, Organa, and their associates are all that seem to know at the end of Episode III.  Ultimately, the Resistance would know about him as they would be fighting him, and Organa could have been able to inform them about his identity and the fact that he is a Force user. The military of the Empire would know of his existence, but even high-ranking members likely wouldn't know his past or identity. However, they would know about the fact that he is a Force user due to his tendency to use his "sorcerer's ways" to choke people.  So, how much would the general public have known about Vader? Would they have known him as just another military leader, or would they have known he was Palpatine's right-hand man? Would they have known about his ability to use the Force, and therefore the possibility that he was a Sith? End of File in C++ Use of comma separating two adjectives Normally, when a user edits one of my posts, I receive a notification like on the following depending on the case   User has editing privilege (click to visit revision)   Users' edit is submitted to review queue (click to visit review queue)     The above notifications were received instantaneously (or less than 30 minutes, in case caching is supposed to be the answer) as the edit was done/suggested.  But I did not receive any such notification today (yet) on an edit made on my . I think it is a possible bug and should be looked at. The recent notifications list I have is shown below: Resources for Blender The limit of a convergent Gaussian random variable sequence is still a Gaussian random variable I'm trying to prove this conclusion but have some problems with one of the steps.  Assume $X_1,\ldots,X_n,\ldots$ is a sequence of Gaussian random variables, converging almost surely to $X$, prove that $X$ is Gaussian.  We use characteristics function here. Since $|\phi_{X_n}(t)|\leq 1$, by dominated convergent theorem, we have for any $t$  $$ \lim_{n\rightarrow\infty}e^{it\mu_n-t^2\sigma_n^2/2}=\lim_{n\rightarrow \infty}\phi_{X_n}(t) = \lim_{n\rightarrow \infty}\mathbb{E}\left[e^{itX_n}\right] = \mathbb{E}\left[e^{itX}\right] = \phi_X(t) $$  this is the step that I cannot figure out: $e^{it\mu_n-t^2\sigma_n^2/2}$ converges for any $t$ if and only if $\mu_n$ and $\sigma_n$ converges.   Let $\mu=\lim_n \mu_n$, and $\sigma=\lim_n\sigma_n$, then $\phi_X(t)=e^{it\mu-t^2\sigma^2/2}$, which proves that $X$ is a Gaussian random variable.  Why can we get that $\mu_n$ and $\sigma_n$ converge? This looks intuitive for me, but I cannot make a rigorous prove. What are my best options for a tripod for up to $100? I'm looking to buy a tripod + head (for my Canon 40D), but am not sure if I want to spend more than $100 on it.  So can you suggest options for best tripods for $100 or less? Or, is it important to spend more than that on a tripod?  Extra props for options which might be available in India. I've installed drush in /usr/local/lib/drush/drush and composer in /usr/local/bin/composer.  When I try to run drush /usr/local/lib/drush/drush I get the following:     /usr/local/lib/drush/drush: line 129: /Applications/MAMP/bin/php/php5.2.17/bin: is a directory /usr/local/lib/drush/drush: line 129: exec: /Applications/MAMP/bin/php/php5.2.17/bin: cannot execute: Undefined error: 0 –    OR the following:     Unable to load autoload.php. Drush now requires Composer in order to install its depedencies and autoload classes. Please see README.md   What am I doing wrong? I'd like to install drush to use with MAMP if anyone has any suggestions. I've done through the readme and nothing seems to be working. R: loading a table with number as the column heading all were wrongly added a X, how to solve it? Question about Casella and Berger's proof of MLE invariance In Casella and Berger, p. 320, they have a proof of the invariance of the MLE. Let $g: \theta \mapsto \eta$ be a function. They define the induced likelihood as  $$ L^*(\eta \mid X) = \sup_{\{\theta: g(\theta) = \eta\}} L(\theta \mid X). $$  This ensures that $g$ is one-to-one with respect to the likelihood functions because if $g$ is not one-to-one, there may be multiple values of $\theta$ that map to a given $g(\theta) = \eta$.  Then they note  $$ \sup_{\eta} L^*(\eta \mid X) = \sup_{\eta} \sup_{\{\theta: g(\theta) = \eta\}} L(\theta \mid X) = \sup_{\theta} L(\theta \mid X). $$  The first equality just applies the definition of the MLE of $\eta$. However, the next inequality confuses me. They write,     The second inequality follows because the iterated maximization is equal to the unconditional maximization over $\theta$...   Can someone justify this claim or provide some intuition if the claim is supposed to obviously follow from definitions? Adding DC voltages of PSU I need to add two voltages together that share a common ground (power supply from computer). I tried using bridge rectifiers and Op-Amps. Package Listings Warning: Text dropped after begin of listing when calling function I'm trying to this:  \newcommand{\code}[1] {\begin{lstlisting} {#1} \end{lstlisting} }   But I keep getting this error:  Package Listings Warning: Text dropped after begin of listing   I'm calling \usepackage and all so, do any of you knows how to solve this? it seems my bash-completion got corrupted. Every time I try to use command substitution, for example when I type  ls $(ls Deskto&lt;Tab&gt;   ..result is..  ls $(ls Desktobash unexpected eof while looking for matching ")".   I tried removing my .bashrc file and cp /etc/skel/bashrc ~/ to get a new one. That works until I add something into my new bashrc. Even when I do echo '#" &gt;&gt; ./.bashrc it breaks again. Removing my bash_aliases did not help either.  Also sudo apt-get install --reinstall bash-completion did not do the trick.  However there are some threads about similar problem, nothing works.  ANY hint will be greatly appreciated! :) Why do modern mountain bike forks no longer use boots on fork stanchions? Older mountain bikes used to have them on the forks, and lefty and headshocks still do. Why have these fallen out of fashion and would putting aftermarket fork boots on your stanchions be productive or not? Where can I find sample or real Selenium projects. All the material I can find on github and on internet are basic, and never intermediate or advanced.  How does a real Selenium project look in real life? How can I find sample code? Best way to reverse a string I've just had to write a string reverse function in C# 2.0 (i.e. LINQ not available) and came up with this:  public string Reverse(string text) {     char[] cArray = text.ToCharArray();     string reverse = String.Empty;     for (int i = cArray.Length - 1; i &gt; -1; i--)     {         reverse += cArray[i];     }     return reverse; }   Personally I'm not crazy about the function and am convinced that there's a better way to do it. Is there?
