I changed my minecraft name and tried to login to the techninc launcher but it said the name was invalid. I know its not since i was able to login in vanilla minecraft but only through the e-mail option and not the username option. Does anyone know how to fix this since the technic launcher does not give me the option to log in through e-mail?
I don't understand this and I'm now worried as I have donated to a lot of servers and I don't want to lose this account. On the launcher it says my new username but when I log on it says "Account not Authenticated with minecraft.net" and "Non-Valid Username".  How can I regain the ability to use my account online?
Word for Party *Steward*? Is there a word that describes a person who is usually not too drunk and takes care of the rest of the folks at a party?  Typically, they're the ones who drag the sloshed ones back to beds, clean up the house and generally maintain a bit of sanity. Ubuntu 18 - how to ungroup apps in dock?

Given the first $b$ birthdays, the probability the next person doesn't share a birthday with any that went before is $(365-b)/365$. The probability that none share the same birthday is the following: $\Pi_{0}^{n-1}\frac{365-b}{365}$. How many people would have to attend a meeting so that there is at least a $50$% chance that two people share a birthday?   So I set $\Pi_{0}^{n-1}\frac{365-b}{365}=.5$ and from there I manipulated some algebra to get $\frac{364!}{(364-n)!365^{n}}=.5\iff (364-n)!365^{n}=364!/.5=.....$   There has to be an easier way of simplifying this. How do I prove or disprove $X \times (Y \cup Z)= (X \times Y) \cup(X\times Z)$  for all sets $X$, $Y$, and $Z$? I'm lost on the steps here. On convergence of Bertrand series $\sum\limits_{n=2}^{\infty} \frac{1}{n^{\alpha}\ln^{\beta}(n)}$ where $\alpha, \beta \in \mathbb{R}$ Study the convergence of $$\sum_{n=2}^{\infty}  \frac{1}{n^{\alpha}\ln^{\beta}(n)}$$ where $\alpha, \beta \in  \mathbb{R}$   I have proved that:   This series diverges when $\alpha \leq 0$. This series converges when $\alpha &gt; 1, \beta &gt; 0$ This series diverges when $0 &lt; \alpha &lt; 1, \beta &gt; 0$ This series converges when $\alpha = 1, \beta &gt; 1$      Question: What happens when $\alpha &gt; 0$ and $ \beta &lt; 0$?   There are other questions on MSE which ask about this series, but this question is distinct because   I would like an argument which does not rely on the integral test for series convergence, and this question considers all real $\alpha$ and $\beta$, while other questions ask only about $\alpha, \beta &gt; 0$, where we can apply Cauchy condensation criterion Shear transform a "box" Using the graphicx package, I can make any arbitrary box rotated using the \rotatebox{...}{...} command.

Why (and how) did using cat on binary files mess up the terminal? If I understand the cat manual correctly:       concatenate files and print on the standard output   cat will take files as argument and print them on standard output. What I don't get is if I use the command:    cat img.png &gt; copy.png   I will obtain 2 png files identical while if I just    cat img.png     I have all chance that my terminal get messed up and misinterpret what I type.     How's that possible?   Binary values are still binary data. Why it does not simply shows a series of 0 and 1 or the interpretation of those binary data in ASCII or whatever the encoding in terminal is?   Is this behavior also possible by cating a text file containing strange characters?   Should a mechanism to prevent this behavior  like try{}catch{} statement should be implemented? Why does the question's closed status disappear when clicking to load a new edit? I've come across a small issue which occurs when a question has been closed but the question itself or one of its answers are being edited.  Steps to reproduce:   Visit a closed question. (even closed years ago)   In a different tab or browser, edit the question or one of its answers. "an edit has been made to this post; click to load" message will appear above the edited post in the first tab/browser, click it. The .question-status div becomes hidden, which includes the closed notice below a question and, for a duplicate-closed question, the list of duplicates above the question body. This gives the appearance that the question is no longer closed (until you refresh).   Some screenshots:                I know it isn't common/important but it did confuse me when looking at a particularly bad question - I thought it had been reopened.   Is this an intentional feature? If so, what was the thinking behind it?

Thanks :) Difference between `dpkg -i` and `apt-get install` From all the other Q&amp;A (like: ) I understand that apt-get is a wrapper over dpkg and provides dependency management.  Assuming I'm installing something that doesn't have any dependencies (or they're also installed at the same time) would there be any difference between installing it using apt-get vs dpkg  E.g. (kinda concrete differences I'm looking for)   say dpkg can not download the pkg from somewhere, I must download before starting installation, whereas apt-get will do this on my behalf. dpkg won't configure pkg, it'll only copy files. apt-get will configure too.   ...

CPT Template Not Showing - Getting 404 Can a multiclass character with 1 level of wizard copy any wizard spell they find into their spellbook? The &quot;Your Spellbook&quot; sidebar for the wizard includes the following line:  Copying a Spell into the Book. When you find a wizard spell of 1st level or higher, you can add it to your spellbook if it is of a level for which you have spell slots and if you can spare the time to decipher and copy it.  Does this mean that a Wizard 1/Cleric 19 can copy any wizard spell they find into their spellbook? Is there anything preventing them from casting these spells?
