Importing two different classes with same name from different packages
Importing two classes with same name. How to handle?
I want to create posters for my poster presentation on a conference. What tools or LaTeX classes are available for preparing posters ? What is a subnet mask, and the difference between a subnet mask of 255.255.255.0 and 255.0.0.0? My DSL/WiFi router provided by my ISP has an internal IP address of 10.0.0.138, the addresses provided by DHCP are in the format of 10.0.0.xxx.  Now, I want to start using static IP addresses on my local network, and I don't know what to provide for the subnet mask.  What is a subnet mask?  Should I be using 255.255.255.0 or 255.0.0.0 as my subnet mask? What is the difference? Since the Earth has a magnetic field, can it, in theory, be run through a conductive metal coil to create electricity? Is $f(x)=10$ a periodic function? In , they give rules so that players can make all the rolls, rather than the DM sometimes rolling for enemies. In one section, there are specifically , which the players roll against, rather than the DM. However, after doing some math, I think they've made a mistake. They say that you convert a Saving Throw into a Saving Throw Check by adding 11 to the defender's saving throw modifiers, and using that as the DC for the check.  The player then rolls against this DC, adding their spellcasing ability modifier and proficiency bonus.  However, according to the following math, this conversion does not produce the same results. In this math, I compare the chances of a player succeeding on a saving throw check, using the rules in the UA article, and of a monster failing its saving throw using the standard PHB rules. If the math is correct, both of these results should have the same chance. These are the formulas I used.  Chance to succeed Saving Throw Check = (20 - DC + 1 + proficiency + casting mod) / 20 Chance to FAIL a Saving Throw = (DC - 1 - save proficiency - save mod) / 20  Assuming a proficiency bonus of +2, +0 for all ability mods, and no save proficiency:  Monster's Saving throw Check DC = 11 + save mod = 11 Chance to succeed a saving throw check DC11: (20 - 11 + 1 + proficiency + casting mod) / 20 = 12/20 = 60% Player's Saving throw DC = 8 + proficiency + spellcasting ability mod = 10 Chance for monster to fail saving throw DC10: (10 - 1 - save proficiency - save mod) / 20 = 9/20 = 45%  If this were a valid conversion, both formulas would result in the same chance of success for the player, and failure for the monster respectively, however, they are off by 15%. This suggests that the unearthed Arcana's rules are not a valid conversion. Are the Unearthed Arcana rules wrong, or is my math wrong? Salesforce - Maximum simultaneous requests callout limit Salesforce says      Maximum simultaneous requests to URLs with the same host for a callout   request is 20   Statement is very simple to read but it is not very clear as to what it means. Can anyone explain what this statement means and how can i reproduce this exception in my Sandbox?     Once more thing what is the difference between simultaneous and   concurrent? Are both same or different? Nicely force 66 characters per line How to prove that it is a group? LIGO has announced the detection of gravitational waves on 11 Feb, 2016. I was wondering why the detection of gravitational waves was so significant?   I know it is another confirmation of general relativity (GR), but I thought we had already confirmed GR beyond much doubt. What extra stuff would finding gravitational waves teach us? Is the detection of gravitational waves significant in and of itself, or is there data which can be extracted from the waves which will be more useful? Workarounds for Sites page to update standard object? trying to install libgraph launch sms application with an intent Odds of rolling doubles or triples given N 6-sided dice Over the holidays I played a dice game where each player had 3 to 7 d6 to roll each turn.  The game gave certain advantages to doubles and triples.  I wanted to know the odds of rolling doubles or triples given N dice to understand the importance of "upgrading" to more dice.  My question is really about how to reason about such problems:  It's easy to see that the odds of rolling doubles with 2 d6 are 1/6 (first die can be anything, and 1/6 of the time the second will match).  It's also easy to see that with 7 dice the odds are 1.0 (6 dice could be 1..6, but the 7th must match one of them).  The middle cases are fuzzier to me.  I ended up writing a program to enumerate all of the possibilities (even 6^7 is only 279,936 cases to evaluate) because that was the only way I felt I could verify any closed formula I came up with.  This also enabled me to distinguish cases of multiple doubles (or triples).  I would like to know how to derive closed forms and how to validate such solutions without brute-force simulation.

If we minimize the Wasserstein loss, $$W_1 (P_S, P_T) = \underset{\gamma \in \Pi}{\text{min }} \sum_{x,y} |x-y|\gamma(x,y)$$ which means we are looking for the coupling $\gamma(x,y)$ that minimizes the cost of moving mass from the source distribution $P_S$ to the target distribution $P_T$,  Do the masses of the source and target distributions have to be identical? If so or not, how are the masses of $P_T$ and $P_S$ accounted for mathematically in, or when minimizing, the shown formula, or what might be missing/overlooked by the Wasserstein approach overall due to the mass differences?

Show Log of the Sql statements that QGIS generates to retrieve Data from Postgis Is there a ways to  - make QGis log its generated SQL Statement or to - force POSTGIS to log all interaction with QGIS?  There is something strange happening to the WFS layer I retrieve in QGIS, since it does  not select all data available in the respective database table. I need to find out, what criteria QGIS chooses in order to narrow down the select set. Deduction of $\forall y \exists x (x=y)$ Give a deduction of $\forall y \exists x (x=y)$  My thinking is I can prove $\exists x(x=y)$ then use generalization theorem， which is equivalent to prove $\neg \forall x \neg (x=y)$ but I got stuck proving this... thanks in advance  Sorry that I did not specify what deduction system that I want to use here, it is the deduction sequence  where ai is either Axiom or original hypothesis or obtained from MP Analogue of the Cantor-Bernstein-Schroeder theorem for general algebraic structures The Cantor-Bernstein-Schroeder theorem states that if there are two sets $A$ and $B$ such that there exist injective (alternatively, surjective, assuming choice I think) maps $A \to B$ and $B \to A$, then $A$ and $B$ are in bijection.  It then seems natural to try to strengthen the result to other structures.  If $A$ and $B$ are, say, groups (or rings, modules, etc) such that there are injective homomorphisms from each to the other, then $A$ and $B$ are isomorphic.  I'm wondering if there are any results on this, or if there are known counterexamples.  The theorem for sets alone is nontrivial, so I feel like any results about how it holds for other structures would be quite interesting.
