I'm building a page in C# and I'm getting a cell value from GridView1 with a code and I'm receiving this:  Tend&amp;#234;ncias de Desfiles   How can I convert it to this:  Tendências de Desfiles   ...using C#? I tried it:  categoria = System.Text.Encoding.UTF8.GetString(System.Text.Encoding.GetEncoding("iso-8859-1").GetBytes(row.Cells[1].Text));   But don't work so please, help me to fix it.
I have email addresses encoded with HTML character entities. Is there anything in .NET that can convert them to plain strings?
Downloading files using wget I am trying to download files from .  The URL is:   When I use this command:  wget http://www.ncbi.nlm.nih.gov/geo/download/?acc=GSE48191&amp;format=file    I get only index.html?acc=GSE48191 which is some kind of binary format.  How can I download the files from this HTTP site? How does the Schengen 90/180 rule work? Simplest or nicest proof that $1+x \le e^x$ The elementary but very useful inequality that $1+x \le e^x$ for all real $x$ has a number of different proofs, some of which can be found online. But is there a particularly slick, intuitive or canonical proof? I would ideally like a proof which fits into a few lines, is accessible to students with limited calculus experience, and does not involve too much analysis of different cases. Why is it true that "I before E, except after C"? Time-ordered operator in Srednicki , "Note that the operators are in time order...we can insert $T$ without changing anything". This I agree with. But then on the next paragraph he states "The time order operator $T$, moves all...where they annihilate...". How correct is this paragraph? Is equation (5.14) always valid? Is equation (5.14) the reason why the time-ordering symbol $T$ appears all over the place in QFT?  The equations I'm referring to are (braket package available?):   $$\langle f|i\rangle = \langle0|~a_{1'}(+\infty)a_{2'}(+\infty)a_{1}^\dagger(-\infty)a_{2}^\dagger(-\infty)~|0\rangle \tag{5.13} $$  and since time goes from right to left inside the braket we put the $T$-symbol  $$\langle f|i\rangle = \langle 0|T ~a_{1'}(+\infty)a_{2'}(+\infty)a_{1}^\dagger(-\infty)a_{2}^\dagger(-\infty)~|0\rangle \tag{5.14} $$   without changing anything.   After this, the $T$-symbol appears everywhere! I want to block my server talking to an external IP address continously.  The IP address in question is I think is being hijacked or spoofed. When Used who.is it resolves to Netherlands. But if you use any other tools it resolves to Jordan.  Any step by step configuration is highly appreciated.  Thank you Kind Regards N What's the typical microclimate in the aircraft passenger cabin? How to escape quotes in shell? I'm having trouble with escaping characters in bash. I'd like to escape single and double quotes while running a command under a different user. For the purposes of this question let's say I want to echo the following on the screen:  'single quote phrase' "double quote phrase"   How can I escape all the special chars, if I also need to switch to a different user:  sudo su USER -c "echo \"'single quote phrase' \"double quote phrase\"\""   Of course, this doesn't produce the right result. What does pwd output? Does the command pwd in a shell script output the directory the shell script is in? sudo credential caching on by default I would like to prove that : If $H$ is a subgroup of $G$ and $K$ is a subgroup of $H$, then  $$|G:K|=|G:H||H:K|$$  I appreciate any clear explanation of this. Thanks ! Precedence of user and group owner in file permissions I just ran into something unexpected (for me) regarding file permissions on Linux (Arch Linux). Basically I have:   userX in groupX fileX userX:groupX ---rwx----   What puzzles me: I cannot perform any action (rwx) on fileX. Is this right? Can someone please confirm this is indeed the expected behaviour?  The only actions I can perform are mv and rm because I have write permissions on the parent directory.  The thing is, I always thought these permissions collapse on each other, starting with the most general one (other -> group -> user). In other words, if o=rwx who cares what the persmissions for group and user are? Apparently this is not the case but it doesn't make much sense to me; it seems counterintuitive. The only thing this approach seems to be useful at, is to easily exclude a very specific person / group, which doesn't seem like a smart way to go at it (imho). Besides, the owner (and group?) should be able to chmod anyway right? Any thoughts on this matter? Populate an entire pre-configured workspace in i3wm Is it possible with I3Wm to populate an entire workspace with determined size, position and commands for each window?  I know I can do i3-msg "exec xterm -e 'ls; bash'" to create a new window, but I can't specify his position and size.  Maybe there is also an alternative by declaring via JSON the layout or something like that? I have a Canon Powershot A710 and I previously had a previous Powershot A-series model. I love them due to the high amount of control they offer. Sadly, they both suck in low light conditions, their flash is very unresponsive, and the camera takes several seconds preparing itself for the next shot after a flash shot. And even then, the pictures they take in low light/flash are as bad as good are those with good light.  I'd like a camera which gives a lot of control options, but what do I need to look for to find one that's great in low light, with or without flash?

How to get a dock on multiple monitors I have two monitors, but only one dock, which is somewhat annoying, so my question is, how do I get multiple docks? (One on each screen) Is it possible to play D&D 5e solo? Is it at all possible to run a solo game where you act as the DM/GM for yourself? I know there was a 4th edition adventure published in an old issue of one of the D&amp;D magazines but recently I read somewhere (Reddit I think) that the games Outbreak: Undead and Eclipse phase were good games to play solo.  Can anyone with experience with running a game of D&amp;D 5e for themselves explain how to do so? Multiple Author and email with location? I am trying to add multiple Author with their email and location but not working.  I am trying to get something like this     first_person^1 , second person^2, third_person^3            {1^mail, 2^mail, 3^mail}@gmail.com                   institution name                      location fastest way to detect if a value is in a group of values in Javascript I have a group of strings in Javascript and I need to write a function that detects if another specific string belongs to this group or not.  What is the fastest way to achieve this? Is it alright to put the group of values into an array, and then write a function that searches through the array?  I think if I keep the values sorted and do a binary search, it should work fast enough. Or is there some other smart way of doing this, which can work faster?
