I am doing a Senior Design Project for my Electrical Engineering degree. This project involves making a PCB. I am having trouble finding a specific library for EAGLE 7.7.0 software. The library that I need is for an NJM2360D Boost Converter. Does anyone know where I can get a library for this component? Please and Thank you!
I'm designing a small module that breaks out a DIP SPI EEPROM to a 2x5 pin header socket(more info here: ). I want to mount the socket on the end of the board, with the pins lying parallel to the board.  I think two 5x1 surface-mount header footprints, on both sides of the board right near the end would do the job. Trouble is, KiCAD doesn't come with such a footprint(if it does, I haven't found it yet). Where might I find one? If one doesn't exist, that's OK; I'll have a shot at making my own.
Is there a formal proof for $(-1) \times (-1) = 1$? It's a fundamental formula not only in arithmetic but also in the whole of math. Is there a proof for it or is it just assumed? Recursive glob? I'd like to write something like this:  $ ls **.py   in order to get all .py filenames, recursively walking a directory hierarchy.  Even if there are .py files to find, the shell (bash) gives this output:  ls: cannot access **.py: No such file or directory   Any way to do what I want?  EDIT: I'd like to specify that I'm not interested in the specific case of ls, but the question is about the glob syntax. finding and replacing elements in a list C# Interfaces. Implicit implementation versus Explicit implementation What are the differences in implementing interfaces implicitly and explicitly in C#?  When should you use implicit and when should you use explicit?  Are there any pros and/or cons to one or the other?    Microsoft's official guidelines (from first edition ) states that using explicit implementations are not recommended, since it gives the code unexpected behaviour.  I think this guideline is very valid in a pre-IoC-time, when you don't pass things around as interfaces.  Could anyone touch on that aspect as well?

I'm planning to visit Vietnam on July 7th and be back in the Czech Republic (in Schengen area) on August 29th. My visa is a multiple-entry, long-term, D type visa (for study purposes) and the expiration date is September 10th. I am afraid that the boarding officer will not allow me to enter EU since the arrival is so close to the expiration date.   Is it OK for me to enter Schengen on August 29th when I have only 12 days left until visa expiration? Old post apocalyptic cartoon where the main character has red hair and lives with a nomadic group I am looking for an animated TV series which was probably made in the '80s or '90s.  The main character had red hair.  The cartoon is set in a post apocalyptic environment and the character lives with his mother and an old man —his mentor I guess— with a nomadic group.  In one early episode, one of the group is wounded in an ambush, he is taken back to the camp where the mentor performs surgery which is revealed he learned during the war. The wound is caused by a bullet, then the mentor is surprised saying that guns were lost and forgotten.  In another episode the main character is captured and sent to a prison. Then after he escapes with other prisoners, they look outside the gate and see grass and soil which they either didn't see in their lives or were in the prison for a long time.  The main character later finds a sword like Excalibur which can cause some sort of electrical disruptions.  I think his mother was kidnapped in the beginning. Why is a deductive closure an intersection of maximally consistent sets?

I want to be able to run Python commands from the Windows CMD. However, if I don't specify Python's full path for each command, I get an error saying "Python is not recognized as an internal or external command, operable program or batch file."  How do I add Python to the Windows PATH permanently? Is there any intuition or meaning regarding Cauchy-Riemann equations? Holomorphic functions are one of the most beautiful objects in mathematics. However, Cauchy-Riemann equations are a little bit of a mystery for me. What does that mean intuitively when a function satisfyes those equations? I want to talk to someone about the house that my wife and I own.  Saying, for example, "My wife's and my house is awesome," sounds a bit funny to me.  What's the best way to express this?  Clarification  I'm asking specifically about the grammar of multiple nouns in possessive form.  I'm particularly curious if it's possible to do this with a first-person pronoun (me).  I am capable of rephrasing this in other ways - my question is not how to express the idea, but about this particular grammatical construction, if it is even legal. I have recently begun self-studying Number Theory, and am working on proving:     Show that every integer $n&gt;0$ can be uniquely written as $$n = \sum_{i=0}^mc_i3^i$$ where $c_i \in \{ -1,0,1\}$ and $c_m \neq 0$.   I believe I have already shown the existence portion of this proof correctly, and now I am looking for some hints on the uniqueness part. So far what I have tried is:     Suppose for the sake of contradiction that there is an alternate representation of $n$ besides $n = \sum_{i=0}^mc_i3^i$, say $n = \sum_{i=0}^pb_i3^i$ where we still have $b_p \neq 0$ and $b_i \in \{-1,0,1\}$.    At this point I felt that I first need to establish that $m=p$, and second show $c_i=b_i$ for each $i \in \{1,2,\dots,  m\}$. To show the former, I left off in my proof by contradiction with      Without loss of generality suppose $p&gt;m$. We know there is an integer $q$ such that $m+q=p$. We have two ways of writing $n$, which means $$ \sum_{i=0}^pb_i3^i-\sum_{i=0}^mc_i3^i=0 \\ \implies \left(\sum_{i=0}^mb_i3^i+\sum_{i=m+1}^{m+q}b_i3^i\right)-\sum_{i=0}^mc_i3^i=0 \\ \implies \sum_{i=0}^m(b_i-c_i)3^i+\sum_{i=m+1}^{m+q}b_i3^i=0 \\ \implies \sum_{i=m+1}^{m+q}b_i3^i=\sum_{i=0}^m(c_i-b_i)3^i$$   At this point I am stuck. If anyone has any hints to help me find the contradiction or feel that there is a better way to establish uniqueness, please let me know! How to open a file manager of the current directory in the terminal? When I work in terminal, sometimes I want to open the current directory in a GUI file manager. And then to click the items in the window to run the application. How can I do this? Automating the scanning of graphics files for corruption Does anyone know of a way to check graphics files (particularly JPEG, GIF, and PNG) for corruption (preferably in an automated way)?    Explanation:  A few days ago, a command worked incorrectly and ended up deleting thousands of graphics files from a FAT32 volume that was practically out of space. I’ve used several different file/photo-recovery programs, but naturally, they are limited in how much they can recover (though fortunately the volume has 8KB clusters, which helps somewhat).  Anyway, some of the larger files, that were fragmented, are now corrupt. Some of them are not even real files at all (the recovery software merely dumped the clusters that were pointed to by now-overwritten directory entries), while others are broken because of fragmentation.  Moreover, because some picture formats embed a smaller version of the picture as a thumbnail, scanning the thumbnails for corruption is not reliable because it may be intact while the actual file (i.e., the picture when viewed full-size), could be corrupt.    Here are a couple of examples:      Here’s the second one. It’s so damaged that it doesn’t display anything.    (A third one wouldn’t even upload because it doesn’t even have the correct header!)

Recently I saw a widget on the Stack Overflow website which says Stack&nbsp;Overflow now has its own currency called "unicoins".

I sent the referral link to my boss and he bought the game and applied his CD key.  He now has a paid account linked to mine:    Yet when I view my World of Warcraft account, it seems they didn't give me the free month. It appears I only have the free month that came with my Battlechest purchase.  I just created and bought my account this morning. Would this affect the free referral month in any way?    We haven't seen each other or partied online in the game yet, do we need to do that first in order for me to receive the month?
