Is it possible to have the same planeswalker from different editions in a Commander deck?
Can I use two different cards with the same name in Commander?
I have developed some custom DAO-like classes to meet some very specialized requirements for my project that is a server-side process that does not run inside any kind of framework.    The solution works great except that every time a new request is made, I open a new connection via MySQLdb.connect.    What is the best "drop in" solution to switch this over to using connection pooling in python?  I am imagining something like the commons DBCP solution for Java.    The process is long running and has many threads that need to make requests, but not all at the same time... specifically they do quite a lot of work before brief bursts of writing out a chunk of their results.  Edited to add: After some more searching I found  which looks decent, but as I'm relatively new to python I guess I just want to make sure I'm not missing a more obvious/more idiomatic/better solution. What is the point of stacking favorite notifications? I noticed I have more notifications than favorites, which means that the notifications are stacked (in other words, there can be more than 1 notification per question).    Here is my reasoning:   Why do they add up?, I don't know where is the benefit of knowing that some of the questions had multiple changes if we are not able to see which questions had how many changes   Since we don't know what questions had what amount of changes, the amount of notifications is just a meaningless number that don't help us too much. Here are some possible solutions:   Add a max of 1 notification per question Keep the same number, but allow us to see how many new changes there were on every question What does the Asterisk * mean in Objective-C? Who is sample No. 118 in The Case of Charles Dexter Ward? In H. P. Lovecraft's The Case of Charles Dexter Ward, Dr. Willett      Enters Joseph Curwen's dungeon and resurrects a dead person identified as No. 118 by reciting the incantation of the Ascending Node over his salts.   Dr. Willett is told by      The resurrected Joseph Curwen, impersonating Charles Dexter Ward, who he secretly murdered,   that   " 'twas Number 118, and I conceive you would have shook had you looked it up in my list in t'other room."  No. 118 himself gives Dr. Willett a note asking the doctor to      kill Joseph Curwen.   It soon becomes clear that No. 118 is opposed to the nefarious dealings that have been transpiring and desirous of being an ally of Dr. Willett.  Who is No. 118?  Earlier in the story,      The grave of Ezra Weeden, a primary instigator in Joseph Curwen's initial downfall and the romantic rival of Curwen, is robbed. There doesn't seem to be any other mention of Weeden in the 20th century occurrences, so without a further connection the passage seems superfluous.   The shared goals of these two people seem to indicate that No. 118 may, in fact, have been that person, but the      Note given by No. 118 to Dr. Willett in eighth century Latin seems to indicate someone much older than Ezra Weeden.   It also occurred to me that No. 118 could be      The recently murdered Charles Dexter Ward himself. Ward's reference to killing Dr. Allen (who is actually an alias of Curwen) and dissolving his body with acid and No. 118's mention of doing the same to Curwen seem to support the idea, but that still doesn't explain the archaic note. Ward is described as writing in a somewhat modern style, at least as opposed to Curwen. It also doesn't explain why Curwen would want to murder Ward if he was going to resurrect him later anyway. Purpose of hole in stove leading to oven I'm staying in a hotel and have access to a "electric coil stove" for one of the first times.  I accidentally turned on the oven light and saw that the light was shining up through only one of the stoves:    There's only a port from the oven into the top right stove, and note that the stove is not on.  Here's a view from within the oven:    Is there a hole here as a vent for the oven for some reason, or is this for the stove? I typically use a glass "flat-top stove" that doesn't have an oven underneath it. I've never seen a direct hole from a stove to the oven before, and have to wonder what the purpose is. Speed of light in a gravitational field? If I use the starting wealth rolls of my class, do I keep any remaining money left over? If I use the starting wealth rolls of my class, do I keep any remaining money left over after I buy equipment?  In D&amp;D 5e you can roll the 4d4 &times; 10 to determine starting gold, forgoing any equipment your class and background  gets.  This is not up for question.  What is up for question is whether or not the PC keeps any remaining gold that they don't spend on equipment.   As far as I have been able to tell, this is not explicitly stated in the PHB nor in the Basic Rules documents. What are the differences between "-" and "--" in commands? I often see a single dash - or double dash -- followed by linux commands or other installed linux programs.   What are the differences between single dash and double dashes?  Is it just about abbreviation?  For example, -v means --verbose most of the time. What are "Commited Memory", "Cached", "Paged", "Not-paged pool" & How They are Different with "In-Use Memory" What’s the difference between "Array()" and "[]" while declaring a JavaScript array? When should you use struct and not class in C#? My conceptual model is that structs are used in times when the item is merely a collection of value types.  A way to logically hold them all together into a cohesive whole.  I came across these rules :   A struct should represent a single value. A struct should have a memory footprint less than 16 bytes. A struct should not be changed after creation.   Do these rules work? What does a struct mean semantically? I am creating a controller for a 12 V system using an Arduino Uno microcrontroller. For the outputs I am using a relay shield to switch the 12 V components. I have a 12 V toggle switch that turns on some 12 V components in the system and I want to use a trigger signal off of this same switch to send to an Arduino digital input. I know that the Arduino can only handle 5 V max. What would be the best way to step down the 12 V coming off of the switch to the 5 V for the input?  EDIT: The system is for use in a car. Would the amperage of the car battery need to be lowered somehow as to not blow up the components? How was Nearly Headless Nick unpetrified? How to close aberrant tooltips in Windows So, here I am, trying to watch The Cleveland Show (TM).      And, as happens from time to time, some program or another has left a modal tooltip.  I don't know which program; how can I lose the tooltip, short of logoff/reboot?  Currently happening on Windows 10, but I have seen it on other versions. How to attribute, give credit to creative commons/copyleft/public domain content for web/print? Edit:   To be extremely succinct: How to credit imagery used on a business card or ballpoint pen?      Inspired by  I started to think:  How do you attribute and give credit, when you use images and resources that are Creative Commons, copyleft; are in the public domain or have variation of "free" licensing?   (Some of the answers to the above questions grazes that question but it is not really the main issue in that question).  How do you attribute - say -:    a background tiled image for web? a background tiled image for print?   (the point here being tiny-weeny images)   an icon set web? an icon set print? To make it more fiddly: tiny images you might use for t-shirts, printed objects such as ballpoint pens, t-shirts, keyrings, letterheads?   For web; there seems to be divided between those who think that in the source code is fine and those who do not. For web you could make a link somewhere discreet that says "credits". This does not really work for print. If you enthusiastically stand on the shoulders of giants, and use what is legally yours to use, your printed leaflet would be bogged down in 6point text attributions.   (Yes, there are differences between countries; I am asking on a general note.)   Edit: I could add GNU licenses, but that is usually pretty straightforward, as it is mainly concerned with software, code, programming snippets, digital programmable objects etc. Alternatives to one-way ANOVA for heteroskedastic data I have data from 3 groups of algae biomass ($A$, $B$, $C$) which contain unequal sample sizes ($n_A=15$, $n_B=13$, $n_C=12$) and I would like compare if these groups are from the same population.  One-way ANOVA would definitely be the way to go, however upon conducting normality tests on my data, heteroskedascity seems to the main issue. My raw data, without any transformation, produced a  ratio of variances ($F_{\max} = 19.1$) which is very much higher than the critical value ($F_{\rm crit} = 4.16$) and therefore I cannot perform one-way ANOVA.   I also tried transformation to normalise my data. Even after trials of various transformations (log, square root, square), the lowest $F_{\max}$ produced after transformation with a $\log_{10}$ transformation was $7.16$, which was still higher compared to $F_{\rm crit}$.  Can anyone here advise me on where to go from here? I can't think of other methods of transformation to normalise by data. Are there any alternatives to a one-way ANOVA?  P.S.: my raw data are below:   A: 0.178 0.195 0.225 0.294 0.315 0.341 0.36  0.363 0.371 0.398 0.407 0.409 0.432     0.494 0.719 B: 0.11  0.111 0.204 0.416 0.417 0.441 0.492 0.965 1.113 1.19  1.233 1.505 1.897 C: 0.106 0.114 0.143 0.435 0.448 0.51  0.576 0.588 0.608 0.64  0.658 0.788 0.958 htdigest file format My question is about one particular usage of static keyword. It is possible to use static keyword to cover a code block within a class which does not belong to any function. For example following code compiles:  public class Test {     private static final int a;         static {         a = 5;         doSomething(a);     }     private static int doSomething(int x) {         return (x+5);     } }   If you remove the static keyword it complains because the variable a is final. However it is possible to remove both final and static keywords and make it compile.   It is confusing for me in both ways. How am I supposed to have a code section that does not belong to any method? How is it possible to invoke it? In general, what is the purpose of this usage? Or better, where can I find documentation about this? Using the Limit definition to find the derivative of $e^x$ I was wondering how we could use the limit definition   $$ \lim_{h \rightarrow 0} \frac{f(x+h)-f(x)}{h}$$  to find the derivative of $e^x$, I get to a point where I do not know how to simplify the indeterminate $\frac{0}{0}$. Below is what I have already done  $$\begin{align} &amp;\lim_{h \rightarrow 0} \frac{f(x+h)-f(x)}{h} \\ &amp;\lim_{h \rightarrow 0} \frac{e^{x+h}-e^x}{h} \\ &amp;\lim_{h \rightarrow 0} \frac{e^x (e^h-1)}{h} \\ &amp;e^x \cdot \lim_{h \rightarrow 0} \frac{e^h-1}{h} \end{align}$$  Where can I go from here? Because, the $\lim$ portion reduces to indeterminate when $0$ is subbed into $h$. How to catch and print the full exception traceback without halting/exiting the program?
