38,125,403 | CraftCMS vs WordPress vs other CMSs | <p>We're considering a new CMS for our huge 10-20,000 page site. We are not currently using any CMS, but have individual html pages with the content embedded(!). </p>
<p>Our site is mostly 'regular' content types, with a few discussion boards and some document handling. We also have a number of news sections/blogs and some profile directories. </p>
<p>We have few developers with limited coding skills and even fewer coders on the team. We've considered WordPress (which we're already using for a few sites) and also CraftCMS. CraftCMS seems more fitting to our needs because it's flexible and lean; we're impressed with what we've seen so far but are concerned that it's not open-source and that it's so new. WordPress seems cumbersome to the coding developers as much of the system is 'out of the box' and requires loading lots of plugins and things that you don't 'need' for a page.</p>
<p>Are there other similar CMSs that people can recommend for us to consider? Please don't tell me about your favorite CMS; please DO tell me about a CMS that you know of that may fit our needs. Comments on the CMSs mentioned above in the context of our needs are welcomed as well.</p>

38,130,046 | Need help writing first VBA code | New to VBA and am in over my head.
I have a table. I would like to write a code that loops through and if the active cell contains a 1, then, in a cell outside of the table, the column heading is returned and put into a comma separated list.
I am looking for that loop to continue all the way across the first row cell by cell, and comma separated list to build with each TRUE return.
Once the loop hits the end of the row I need it to drop down to the next row and continue the same process (but creating its own comma separated list for those that returned true in row 2).
Any help would be greatly appreciated.
I know I need to somehow loop and if statement but just can't figure it out right now.

So if I want to update my site made in notepad++ can I use wordpress? And if I use wordpress do I need to use ftp anymore? My website will be like a blog with different articles so I will update it regularly. I know enough HTML and CSS for building my site and never published a website before so i don't know the correct steps.

38,149,647 | insert .css into html on omeka | Hi I am working on building a webpage using omeka. I am working in a simple page that automatically creates HTML code. It generates this code based on the theme you select. The site has the ability to edit the css through an extension of the site. However, with the theme that was desided for the site you cannot use the css editor to format the page. You have the ability to add html short codes. I would really like to reformat the text and the background for this page in particular without changing the settings for the rest of the site. A way to do that is by inserting css code into the html. The problem is I am not sure where to insert the code at.
Here is an example:
[click to see][1]
(sorry if images are poor quality)
Where would I insert the suggested css
When I do this it changes either the alignment or text color but it will not do both. What am I doing wrong and how can I fix this? I am fairly new to coding and most of my expierence is working with css not html.

Question #2: Can I build destructor in this way, instead of the way I used in my program.
Circle::~Circle()

std::cout << "The road would cost " << SwimmingPool.AreaP(r) << std::endl;

38,153,471 | fasted way to read file in python | I made a python script to analyze logs. I have one observation to share, and two questions to ask.
When I use gzip.open to open each file and go through every line, it takes around 200 seconds just to going through all the lines and files.
with gzip.open(file) as fp:
for line in fp:
If using `zcat` and `grep` to do the work, it takes about 50 seconds.
temp = commands.getstatusoutput("zcat file* | grep pattern")
The performance difference is too huge to ignore. Is there a better way to reduce the gap?
I also noticed that the `commands` module is made obsolete by the `subprocess` module, which seems always create a temporary file. But it wouldn't be convenient, what if it is not possible to create a temporary file from where the python script is running? Any suggestion?

38,174,331 | C#, Windows Forms, DataGridView: Why am I Getting Null DataTable? | OK guys. It's been a LONG time since I worked with DataGridViews, so please help me understand what I am doing wrong. I created a very simple test to boil this issue down to common elements. I have an MS Access DB with 1 and only 1 table in it. 2 columns (ID, Name) and added 4 rows of data to the table. I added a datasource to my Winforms project and added a test form with 1 and only 1 control, a datagridview, and bound that grid to the table in the datasource. My Form_Load looks like this:
private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'testDBDataSet.TestTable' table. You can move, or remove it, as needed.
this.testTableTableAdapter.Fill(this.testDBDataSet.TestTable);
// TODO: This line of code loads data into the 'testDBDataSet.TestTable' table. You can move, or remove it, as needed.
this.testTableTableAdapter.Fill(this.testDBDataSet.TestTable);
BindingSource bs = (BindingSource)dgvTestData.DataSource;
DataTable dt = (dgvTestData.DataSource) as DataTable;
}
When I step past the last line of code, dt is null. What am I missing? I know it is something simple and probably obvious, but I don't see it. If I just run the code back to the form, the datagrid has data in it. What am I doing wrong?

<p>How I can change the datatype of date field from string to date type with a particular format.</p>
<p>I tried to change the mapping of a string datatype to change it to <code>eager</code> loading and <code>not_analyzed</code> from analyzed, but it gives the following error:</p>
<pre><code>{"root_cause":[{"type":"illegal_argument_exception","reason":"Mapper for [AppName] conflicts with existing mapping in other types:\n[mapper [AppName] has different [index] values, mapper [App

existing mapping in other types:\n[mapper [AppName] has different [index] values, mapper [AppName] has different [doc_values] values, cannot change from disabled to enabled, mapper [AppName]
rent [analyzer]]"},"status":400}
</code></pre>
<p>Here is my query for the same:</p>
<pre><code> curl -XPUT localhost:9200/logstash-*/_mapping/log?update_all_types -d "{
"properties":
{"AppName":
{
"type": "string",
"index" : "not_analyzed",
"fielddata":{"loading" : "eager"}
}
}
}"
</code></pre>
<p>However, if I change it from <code>not_analyzed</code> to <code>analyzed</code> it gives a <code>acknowledged=true</code> message. How can I change the analyzer. </p>

<h3>What is(are) the correct scenario(s) to use <code>promise.all()</code></h3>

However according to the document http://jmeter.apache.org/usermanual/component_reference.html#Aggregate_Report,
Throughput = (number of requests) / (total time in secs)

which means ``` Average * Throughput``` should almost be ```1000 ```.

Based on my research if I remove <strong>x86</strong> JS binary files from React Native the apk size could be as small as 4mb. I suppose the 4mb does not include the JS files and images so client needs to download that first time when he/she opens the app, is that correct?<br />

38,187,833 | How to combine ReactJs Router Link and material-ui components (like a button)? | <p>I need to find a solution to be able to combine together the functionality of react router with the material ui components.</p>
<p>For instance, I've this scenario: a router and a button. What I tried to do it is to mix them together, and restyle them.</p>
<p>So from a simple link</p>
<pre><code><Link className={this.getClass(this.props.type)} to={`${url}`} title={name}>{name}</Link>
</code></pre>
<p>I tried to create a material ui button as the following</p>
<pre><code><Link className={this.getClass(this.props.type)} to={`${url}`} title={name}>
<FlatButton label={name} />
</Link>
</code></pre>
<p>but I have the following error and Javascript breaks</p>
<blockquote>
<p>invariant.js?4599:38Uncaught Invariant Violation: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's <code>render</code> method, or you have multiple copies of React loaded (details: <a href="https://gist.github.com/jimfb/4faa6cbfb1ef476bd105" rel="noreferrer">https://gist.github.com/jimfb/4faa6cbfb1ef476bd105</a>).</p>
</blockquote>
<p>Do you have any idea how to manage this situation?
Thank you in advance and if you need more information let me know</p>
