What is a wave?
Large text files load not working on android Does anyone know?  And a bigger question is what happens when you encounter this maximum? Is this the same number with other Windows OSs such as Vista, XP etc.? Is there a RSS to the 'Stack Exchange Inbox'? How about to Activity? Just wondering if I'm missing something here. Also, I couldn't find any previous question related to this. Is "architect" a verb and a noun? I hear the word architect used as a verb in the technical field and now more often in other industries and groups, for example:     We need to architect a better solution to the problem.   I am interested if this is considered acceptable usage, as I see this word being used more in published technical documents (not necessarily books, but corporate publications).  I can see how a conductor can conduct, a typist can type, but can a scientist "science"?  A scientist might research, analyze, and so forth, as an architect might design, create, build, etc.  Merriam-Webster , however, I have been told that other dictionaries exist that define architect as both a noun and a verb&nbsp;— is there a credible reference or source that authoritatively answers this question? I've been try to download Xcode for work, but for some reason the Mac App Store is giving me a bit of trouble. Activity monitor shows some network usage, but in Launchpad it seems the download isn't moving.   When I go to the purchases panel of the Mac App Store, I see this.     No status, no pause button, in fact - the button has no text on it! I've tried restarting the App Store, restarting my computer, even removing the com.apple.appstore folder in /var/folders but alas, no luck.  Can anyone diagnose the issue? When I removed com.apple.appstore, Xcode still showed up on Launchpad, and clicking on it did nothing - it was frozen in time. So can I kill off this partial download and start new? Is $\int \frac{1}{2x} \, dx $ equal to $\frac{\ln|2x|}{2}+ C$ or $\frac{\ln|x|}{2}+ C$ Reasoning for $\frac{\ln|x|}{2}+ C$ :  $$\int  \frac{1}{(2x)}  \, dx = \frac{\ln|2x|}{2}+ C$$   Check: By taking derivative we get $\frac{1}{x}$  Reasoning for $\frac{\ln|x|}{2}+ C$ :  $$\int  \frac{1}{2x}  \, dx = \frac{1}{2}\int  \frac{1}{x}  \, dx =\frac{\ln|x|}{2}+ C$$  Check: By taking derivative we get $\frac{1}{x}$  Question: Is  $\int  \frac{1}{2x}  \, dx $ equal to $\frac{\ln|2x|}{2}+ C$ or $\frac{\ln|x|}{2}+ C$? How to show that $L^p$ spaces are nested? Suppose $1&lt;p_1&lt;p_2&lt;\infty$, then show $L^{p_1}[a,b] \supset L^{p_2}[a,b]$.  I was able to show $\|f\|_{p_1} \le \|f\|_{p_2} (b-a)^{1/p_1 - 1/p_2}$ but I'm not sure how to proceed from here. AES and DES - reusing the same round keys There are many different kind of options that you can do  in order to start using LaTeX on Ubuntu. I would prefer doing that through Eclipse, but if there is a better way of doing it, feel free to write your opinion on why using this instead of something else. View history of commands run in terminal Is there a way to save all my typed terminal commands and view it like history in a log book? Why do I get the same result with rand() every time I compile and run? How do I change permissions on a FAT32 formatted drive? I am using Microsoft Visual C++ on Windows and Qt Creator on Ubuntu. I can't change permissions on my flash drive (FAT32), even as root.  How can I change permissions on a FAT32 flash-drive? MySQL Database User: Which Privileges are needed? The short installation instruction for WordPress () state that:     Create a database for WordPress on your web server, as well as a MySQL user who has all privileges for accessing and modifying it.   While setting up a new blog professionally I was wondering how that maps to what the MySQL database user privileges/permissions configuration offers me:   Data: SELECT, INSERT, UPDATE, DELETE Definition: CREATE, ALTER, DROP Extra: INDEX More:  LOCK TABLES REFERENCES CREATE TEMPORARY TABLES CREATE VIEW SHOW VIEW CREATE ROUTINE EXECUTE ALTER ROUTINE    I'm pretty sure for the first three groups, I named them Data, Definition and Extra here. But what about the others below the More entry? Normally I would say, those are not needed, but I would like to get a second opinion. How would I be able to get N results for several groups in an oracle query.  For example, given the following table:  |--------+------------+------------| | emp_id | name       | occupation | |--------+------------+------------| |      1 | John Smith | Accountant | |      2 | Jane Doe   | Engineer   | |      3 | Jack Black | Funnyman   | |--------+------------+------------|   There are many more rows with more occupations.  I would like to get three employees (lets say) from each occupation.  Is there a way to do this without using a subquery? Abort Ajax requests using jQuery I'm looking for a 90s (or early 2000s) scifi (mini)series where a boy and old man chase a black guy in metal suit. I think they were going through different dimensions. I remember part of it, but I don't think I ever saw how it ended. I remember my friend telling me there was a twist at the end. I think they were trying to find something and he was always ahead of them.. I wish to calculate the volumes of a truncated cone whith asymetry over all axes and ellipses as base and top - how do I do that?  I have height and radii of the corresponding ellipses. (I assume correctly I need the geometric means of the 2 radii describing the ellipsis.)  Kind Regards So I'm trying to install Visual Studio 2015 Community on my Windows Server 2012 R2 box which will end up being a Jenkins build server. Attempting to do so gives an error saying that I need to install KB 2919355.    So I attempt to download the right KB from the . The two files that I would assume to work are either Windows8.1-KB2919355-x64.msu and Windows8.1-KB2919355-x86.msu (just to try) and neither update work, saying that the update is not applicable.    I've not been able to get this working and I haven't been able to find a proper way to fix this. Can anyone offer any suggestions or solutions?
