Two simple C# Inheritance methods result in different output
Difference between shadowing and overriding in C#?
Where's the Rainbow Jetpack gone in Jetpack Joyride? Ignore folders/files when Directory.GetFiles() is denied access I'd like to declare some new operators using \DeclareMathOperator and some of the names are already taken by other commands (that I do not want to use). Is there an equivalent to the \renewcommand command for \DeclareMathOperator or a different way to overwrite the commands using \DeclareMathOperator? Evaluation of $\int\frac{1}{x^2.(x^4+1)^{\frac{3}{4}}}dx$ Remove only the commas present within the double quotes In a text file, I want to remove , (commas) and also the " (quotes) (only if the double quotes  contains  numbers separated by commas).  56,72,"12,34,54",x,y,"foo,a,b,bar"   Expected ouput  56,72,123454,x,y,"foo,a,b,bar"   Note: I show the above line just as an example. My text file contains many lines like above and the numbers separated by commas present within the double quotes should vary. That is,  56,72,"12,34,54",x,y,"foo,a,b,bar" 56,92,"12,34",x,y,"foo,a,b,bar" 56,72,"12,34,54,78,76,54,67",x,y,"foo,a,b,bar" 56,72,x,y,"foo,a,b,bar","12,34,54" 56,72,x,y,"foo,a,b,bar","12,34,54","45,57,84,92","bar,foo"   Expected output:  56,72,123454,x,y,"foo,a,b,bar" 56,92,1234,x,y,"foo,a,b,bar" 56,72,12345478765467,x,y,"foo,a,b,bar" 56,72,x,y,"foo,a,b,bar",123454 56,72,x,y,"foo,a,b,bar",123454,45578492,"bar,foo"   There a n number of numbers present within the double quotes separated by commas. And also leave the double quotes which contains characters as it is.  I love sed text processing tool. I'm happy if you post any sed solution for this. Panasonic Eneloop BK-3MCC (4th gen) - where I can find maximum discharge current? Im looking for some official information source about maximum current for Panasonic Eneloop BK-3MCC rechargeable batteries.  All I found is , there is just 1 table (nothing about maximum discharge current), charge and discharge characteristics.  UPDATE LINK:   / edited - I fixed my mistake, I meant 6A not 8A /  There is discharge characteristic for 6000mA discharge. So... I can safely draw 6A from that AA cell? What's the difference between the five masses: inertial mass, gravitational mass, rest mass, invariant mass and relativistic mass? Switch off Windows Update for a particular program or feature I'm getting really tired of unchecking the same Windows Update candidates so save hundreds of MB's of dowbloads, especially for programs I never use, that are in fact not even installed, and those I don't wish to update.  Is there any way to permanently, or until another explicit change, to turn off certain updates?  There is an option called 'Hide update', but that unsettles me a bit. Is  && statement() the same as if() statement()? Delete an old Facebook account Two years ago somebody made a fanpage for our company, but that person doesn't work here anymore.

Children's fantasy series with a symbol consisting of a circle divided into quarters I read this book series as a kid back in the late 1970s, so it's an old series - and my memories are similarly old, and vague.   I know it's a fantasy series. I think there are 4 books in the series. Or perhaps 7.  There's a central boy character who has to get a collection of magical objects (every fantasy needs a quest!), each of which represents a different magical 'element': wood, stone, fire, etc. I definitely remember there was a wooden object. He lives in our normal world. The whole series takes place "here &amp; now". I have a feeling he's a "chosen" person of some kind... But, the strongest memory I have is of a symbol: a circle which is divided into quarters (a vertical bar and a horizontal bar).  I know it's vague, but does anyone recognise this? There is no fruit jet pack. I can't get it. How do I get it? I looked at the jetpacks many times. There are none. I think it would be nice to have a "friends list" on Stack Overflow. This would allow us to be able to follow the questions and answers that are posted by users that we want to watch/monitor.  I suggest it be implemented in the same fashion as DotNetKicks.com; where you can add someone to your "friends list" without them needing to approve you the way that other social networks do it. It should be completely open for us to add anyone to our "friends list" that we like. Why does the Taylor expansion of $e^x$ satisfy exponential properties? Do not give the impression that all votes are unanimously in favor of the winning close-reason. I closed for "belongs on superuser," yet SO claims I closed for a completely different reason.  Source: 7 month old wants to sleep on its belly -- is it safe? Neural Network: MLP for regression with 3 continuous features, 1 categorical I am starting to study Neural Network. I want to build a MLP where I will feed it:   3 features which are continuous one feature which is categorical (48 classes)   How can I do this?  Before adding the categorical feature, I was using 'relu' activation function and 'lbfgs' as a solver in MLPRegrssor in sklearn.  I was wondering: how can I integrate this variable into the network? Should I do one-hot encoding? Should I keep relu as activation function or should I try sigmoid, softmax or something like that?

Using RegEX To Prefix And Append In Notepad++ I have quite a large list of words in a txt file and I'm trying to do a regex find and replace in Notepad++. I need to add a string before each line and after each line.. So that:   wordone wordtwo wordthree   become   able:"wordone" able:"wordtwo" able:"wordthree"   How can I do this? In short, :     If you go before the Board of   Directors and ask for 1.5 billion   dollars to build a nuclear reactor, no   one will review or discuss the details   of the plant. They will assume that   experts have been over every inch of   the plans, and not want to look   foolish by asking a silly question.      However, if you ask the same group to   approve a 30 dollar expenditure for   lumber with which to build a bikeshed   (presumably a British term for the   smallest possible building) then be   prepared for a 45 minute discussion   about all aspects of the bikeshed,   including the color of the paint. The   explanation for this is that everyone   can grasp the scale of a bikeshed.   To transform this problem to Stack Overflow terms, questions that are trivial such as "How to convert a C string to a QString or "What is the difference between . and ->" get a lot more views, answers and votes than real questions of the form "How do I frob this widget" that bother real professionals. Fewer views mean less possible votes for good answers and hence less incentive for people to answer.  How can Stack Exchange solve this problem?
