I know that a tag wiki "is an editable page that briefly summarizes the topic of the tag and that may provide links to existing questions that are often useful to many people."   How can we find the tag wiki content? Is there a data dump available for downloading the tag wiki content?
Is it possible to include the tag-wiki associations in the Data Explorer? To do this would require two additional columns in the postTags table that associate a tag wiki excerpt and a tag wiki to their tag.  The tag wiki data is already available in the posts table. But there is no way to associate this data with its tags. The SEDE schema lacks the required columns to link the tag excerpt and the tag wiki to the tags table.  Additionally, the postTypes table only lists three posts types. It makes no mention of tag-wiki and tag excerpt posts. Perhaps the postypes table can be updated to reflect the additional post types?
What are the uses of "using" in C#? User  answered the wonderful  question by mentioning the using keyword. Can you elaborate on that? What are the uses of using? How do you properly use namespaces in C++? I have to solve: $\lim\limits_{x\to \infty} \frac{\ln(x+1)}{\ln(x)}$. Can you give me any hints to go? Thanks a lot! Proving $\frac{\sin x}{x} =\left(1-\frac{x^2}{\pi^2}\right)\left(1-\frac{x^2}{2^2\pi^2}\right) \left(1-\frac{x^2}{3^2\pi^2}\right)\cdots$ How to prove the following product? $$\frac{\sin(x)}{x}= \left(1+\frac{x}{\pi}\right) \left(1-\frac{x}{\pi}\right) \left(1+\frac{x}{2\pi}\right) \left(1-\frac{x}{2\pi}\right) \left(1+\frac{x}{3\pi}\right) \left(1-\frac{x}{3\pi}\right)\cdots$$ Is there a way for me to download the full list of tags (and synonyms) used on Stack Overflow? My intent is to import these tags into an SQLite database as part of a process to convert all of my delicious bookmarks and tags to the ones used here on Stack Overflow. Is it physically possible to build a long zoom (17-300 mm for example) at an aperture value of around 1.4 or 1.2? I'm curious if the physics allow a company to build such a lens of course with good IQ, minimal color aberration, maximum sharpness, and little to none lens vignetting or edge softness I made a map with annotations in QGIS 3.0.  This is how it looks like in the layout view:    If I print the map as PDF, one would expect to get the PDF to be WYSIWYG, right? However, it looks like this (it's about half the size):    Is there a way to influence the the scaling of the Annoations? I already tried to play with the Scale and Magnifier in the map view. I also tried to change the Scale in the map item.   The strange thing is, I believe it worked a few days ago. But today I installed QGIS 3.0 on a new PC and it showed the same behaviour... Using Python to convert from more than one CRS I have a Python function which converts Eastings and Northings to Latitude and Longitude if line_count == 0:                     keys = row                     print('keys', keys)                     line_count += 1                 else:                     inProj = Proj(init='epsg:27700') # British National Grid                     outProj = Proj(init='epsg:4326') # WGS84                     x1, y1 = row[1], row[2]  # easting, northing                     x2, y2 = transform(inProj, outProj, x1, y1)                     row[1], row[2] = y2, x2                                          json_doc = {}  At the moment it converts from epsg:27700 (British National Grid) to WGS84, however there is a possibility I will get TM75 Irish Grid too. Is there any way I can get Python to recognised which CRS is applicable for the conversion? Which singular names ending in “s” form possessives with only a bare apostrophe? Ubuntu copy dialogue stops at the last moment for a long time Whenever I try and copy a file to an USB flash disk, the progress bar runs till the end very fast and stops for an indeterminable time before it is complete.  Is there an issue with ubuntu or my flash disk is what I am not able to figure out. All I want is a realistic copy dialogue How to mount a remote (over SSH) directory to be available like a local directory (incl. in shell, not just in Gnome)? Understanding the proof for $\gcd (F_n, F_{n+k}) = 1$ where $F_n$ is a Fermat number I'm trying to understand the following proof of why      No two Fermat numbers have a common divisor greater than $1$.   Hardy and Wright show the following proofs:   If $x = 2^{2^n}$, we have  $$\frac{F_{n+k} - 2}{F_n}(\circ) = \frac{2^{2^{n+k}}-1}{2^{2^n}+1} = \frac{x^{2^k}-1}{x+1} = x^{2^k-1} - x^{2^k-2} + \ldots -1$$  The main issue I'm having is the $\circ$ part. I don't understand how they get that. The rest of the proof makes sense but the first part is really confusing me. Can someone please explain where they get that fraction?  Thanks a bunch! How to find the list of all available packages along with the lastest version number available in the repositories? I want to list all the packages(installed or not installed) along with the latest version number available in the repositories.  For example:  The output of apt-cache policy chromium-browser shows like below  $ apt-cache policy chromium-browser chromium-browser:   Installed: (none)   Candidate: 34.0.1847.116-0ubuntu2   Version table:      34.0.1847.116-0ubuntu2 0         500 http://ftp.cuhk.edu.hk/pub/Linux/ubuntu/ trusty/universe amd64 Packages   So the latest version of chromium-browser package available in the repository is 34.0.1847.116-0ubuntu2. Like that, i want to list the version number along with the package names that are available in repositories. And all i want to do this through command-line.  I want the output to be like this,  chromium-browser 34.0.1847.116-0ubuntu2 xxxxxxxxxxxxxx   yyyyyyyyyyy ............     ............ When should \cdot be used to indicate multiplication? Is this purely personal style, or are the generally accepted guidelines? Clearly, when dealing with numbers either $2 \cdot 2$ or $2 \times 2$ is needed, but within formulae where an absence of an operator implies multiplication, when should a \cdot be used? I tend to use it only sparingly if it aids in grouping. (Of course, barring the cases where it's required, e.g. a dot product.) How to find the most famous questions on Stack Overflow?

When I was going through my contacts today, I noticed a lot of email adresses stored along with the other numbers. I didn't even know most of them! What has happened? bi-directional sync with rsync I am trying to setup bi-direction or two way sync with rsync. In my case I only need to delete the files when syncing from B to A. So, I was thinking of running rsync twice as follow :  rsync -rtuv ./A/ ./B/ rsync -rtuv --delete ./B/ ./A/   This problem with this solution is that when I run rsync (B->A) which would be right after running the rsync (A-B), Any new file that get created in between the sync will also get removed.  Is there a way I can specify a time stamp as condition that it only delete the file if it created before this date/time.  Updated:  I understand there is a unison solution but the problem with unison is required to install on both ends. I am syncing with a remote server and I can not install unison on the remote end.
