How can I start to learn web development? I'm very interested in learning web development and have learned some basics regarding HTML and CSS a few years back from W3Schools, but I never learned how to develop websites that are up to today's standards, i.e. free-flowing sites without the use of tables to govern the design of the site.  What are some good resources that I can start with? What is the difference between the three sentences below?   I have been married with her for three years. I was married with her for three years. I married her for three years. What is considered a "real question"? Note:   This close reason is old and only applies to old questions that were closed prior to the closing overhaul. This has been replaced by the reasons "unclear what you're asking" for unclear questions and "too broad" for overly broad questions. Older questions that have been closed as "not a real question" will remain closed under this reason, so this question is left here for reference.   Questions used to be closed as "not a real question."     What makes a question a "real" question? What are new users expected to know about asking "real" questions? Why does SE treat questions differently from other online forums? I run processing.run(&quot;native:buffer&quot;) and from newly created vector I get all features and export them to string using QgsJsonExporter(). My problem is that newly created vector gives new IDs to all features and they aren't equal to attribute ID's values. And after exporting them to GeoJSON using QgsJsonExporter() I get GeoJSON features with identifiers. However I can solve this by declaring processing.run(&quot;native:buffer&quot;) algorithm OUTPUT to .geosjon file and opening it afterwards. Is there a way that I can get GeoJSON string without IDs without having to save OUTPUT to .geojson and reading it to string afterwards. vl = QgsVectorLayer(sys.argv[1],&quot;mygeojson&quot;,&quot;ogr&quot;)  def runProcessingNativeBuffer(inputGeoJson, distance):     processing.algorithmHelp(&quot;native:buffer&quot;)     return processing.run(&quot;native:buffer&quot;,                          {'INPUT': inputGeoJson,                           'DISTANCE': distance, 'SEGMENTS': 5,                           'END_CAP_STYLE': 0, 'JOIN_STYLE': 0,                           'MITER_LIMIT': 2, 'DISSOLVE': False,                           'OUTPUT': &quot;TEMPORARY_OUTPUT&quot;})  ats = runProcessingNativeBuffer(vl, sys.argv[2])  vl1=ats['OUTPUT']  features = vl1.getFeatures() exporter = QgsJsonExporter() print(&quot;GEOJSON&quot;,exporter.exportFeatures(features))  IDs in properties are fine I don't need additional IDs in &quot;features&quot; How are Contacts in Marketing Cloud counted? Salesforce bills Marketing Cloud on total number of Contacts within the system. I'd like to know what exactly is used to count these? Is this the Email Studio > All Subscribers list or the Contact Builder > All Contacts list?  When we have Marketing Cloud connector and synchronise the Contacts object, is this counted towards that number? (or only when they have been inserted into the All Subscribers / All Contacts list, as they are not done so automatically) Find the coefficient of the term $x^2$ in $\left(x+\frac 2x\right)^{4}$ Find the coefficient of the term $x^2$ in $$\left(x+\frac 2x\right)^{4}$$   This is what I have done so far.  We know $a$ = $x$ and $b$ = $\frac2x$ and $n$ = 4  So what I have done is $4c2$ x $(x)^2$ x ($\frac2x$)$^2$  As we know that $^2$ + $^2$ = 4, and 4 is the $n$ value.  The answer is one though?  What have I done wrong?   P.S.  was the tutorial that helped me. How do I get rid of the noise on my Hayes Stroker Trail brakes How to check if file exists on FTP before FtpWebRequest How to create a custom Windows 7 ISO file Should seemingly arbitrary things like "play piano for Church" or "intramural badminton" go on M.S. or PhD applications in sciences/engineering? And if they should, I assume that these things should go on a resume under something like "Activities and Community Service". I mean I consider being able to sight read music to play at my Church as a significant feat (how many people can do that?) and might sway one person on an admissions committee if he or she enjoys music and understands how hard one must have worked to accomplish this.   Badminton?.... perhaps not so much How to prototype? How is prototyping done in a professional EE environment? Do you do your prototypes on breadboards, on copper clad boards, Manhattan style, or do you just draw schematics, order PCBs made and assembled and work with them, hacking here and there if necessary? I was reading through some of the questions and answers here on the Rings of Power and I just wondered why the ring effects, affected different races in a slightly different way.  I know other questions ask and answer some of these things, but I just wondered why the Rings of Power caused greed in Dwarves for ever more amounts of treasure.  It's true that Dwarves loved mining and loved wealth and were built of sturdier stuff than men, but why did the Rings of Power not control Dwarves in the way the other Rings of Power controlled men and why did it produce greed and not invisibility? If the sum of $n$ cubes is zero, then the sum must be no larger than $\frac n3$. Assume that $a_1,...a_n$ are real numbers and $-1 \leq a_i\leq 1$ for $1\leq i\leq  n$. If $$a_1^3+\ldots +a_n^3=0$$ Then show that $$a_1+a_2+\ldots+a_n\le n/3$$   I just came cross this problem the other day. I totally have no idea how to prove it. Are there any hints about which theorem, principle or method to apply? Indicator icons do not appear after upgrade to Ubuntu 17.10 How do I clear command prompts in minecraft? Challenges with Key with Gaps? Checking from shell script if a directory contains files From a shell script, how do I check if a directory contains files?  Something similar to this  if [ -e /some/dir/* ]; then echo "huzzah"; fi;   but which works if the directory contains one or several files (the above one only works with exactly 0 or 1 files). I have used Windows since childhood, and when I hear the phrase "Windows filesystem" I think of directories (folders) within directories, a folder called SYSTEM, a folder called PROGRAM FILES etc. Is this what the system is? Just the layout of the folders?  And then I recently started using Linux, and my reference book says in the linux filesystem everything starts at root and branches off from there. How is that really different from Windows? I mean, it seems the linux system and the windows system are just two ways of setting up a directory tree.  Is this what file system means? Derivative of function with 2 variables I'd like to create a chart where the column titles are rotated, as per this toy example:    I used the rotating package to generate the above. It has certain shortcomings: the rotate command doesn't leave space for the titles, so I have to manually space things to prevent overlaps. The turn command, by contrast, creates too much space, where each column is the width of the entire rotated column title.  There is also no easy way to have long titles be split into multiple lines.  Is there a package for creating tables of this sort, or at least one that would relieve some of the manual placing and spacing that goes into creating such a table?    This question is more to make sure I don't miss any easy way of doing what I want than seeking help on manually doing it, but the code for above is included anyways:  \begin{tabular}{r|ccc} &amp; \begin{rotate}{60} Property 1 \end{rotate} &amp; \begin{rotate}{60} Property 2 \end{rotate} &amp; \begin{rotate}{60} Property 3 \end{rotate} \\ \hline System 1        &amp;       &amp;       &amp;  X    \\  System 2        &amp; X     &amp; X     &amp;  X    \\ System 3        &amp; X &amp;   &amp;  X    \\ \hline \end{tabular}
