I'm trying to hide the 'add to cart' button for some products (based on the type of product and custom variable is_customized).  If the custom variable is_customized is true only then show the 'add to cart' button.  I cannot find a hook using which I can remove/hide the button and then add it again if the is_customized is true.
I am using a plugin to help "build" a customized product. There are different tabs/steps the user has to go through with back and continue buttons. At the last step I would like to add an "agree to terms" box with a checkbox "Agree". I have this done. But I would like to hide the add to cart button in Woocommerce until the user selects the checkbox agreeing to the terms.  This will be beneficial to me to make sure they reviewed the return policy as well as avoid confusion with the add to cart button appearing during all the steps, assuring they go through all the steps.  Here is the checkbox coding i pulled from console:  &lt;ul data-rules="{&amp;quot;Agree_0&amp;quot;:[&amp;quot;&amp;quot;]}" data-original-rules="{&amp;quot;Agree_0&amp;quot;:[&amp;quot;&amp;quot;]}" data-rulestype="{&amp;quot;Agree_0&amp;quot;:[&amp;quot;&amp;quot;]}" data-tm-validation="{&amp;quot;required&amp;quot;:true}" class="tmcp-ul-wrap tmcp-elements tm-extra-product-options-checkbox tm-element-ul-checkbox element_16 termsbox-ul"&gt;     &lt;li class="tmcp-field-wrap tmhexcolorimage-li-nowh"&gt;         &lt;label for="tmcp_choice_16_0_35"&gt;    &lt;input class="tmcp-field termsbox tmhexcolor_16_0_35 tm-epo-field tmcp-checkbox" name="tmcp_checkbox_16_0" data-limit="" data-exactlimit="" data-minimumlimit="" data-image="" data-imagec="" data-imagep="" data-imagel="" data-image-variations="[]" data-price="" data-rules="[&amp;quot;&amp;quot;]" data-original-rules="[&amp;quot;&amp;quot;]" data-rulestype="[&amp;quot;&amp;quot;]" value="Agree_0" id="tmcp_choice_16_0_35" tabindex="35" type="checkbox"&gt;     &lt;span for="tmcp_choice_16_0_35"&gt;&lt;/span&gt;&lt;span class="tc-label tm-label"&gt;Agree&lt;/span&gt;&lt;/label&gt; &lt;span class="price tc-price  hidden"&gt;     &lt;span class="amount"&gt;$0.00&lt;/span&gt; &lt;/span&gt;&lt;i data-tm-tooltip-html="This is were the description will be to agree" class="tm-tooltip tc-tooltip tcfa tcfa-question-circle"&gt;&lt;/i&gt;     &lt;/li&gt;&lt;/ul&gt;   Here is the add to cart section with the quantity  &lt;div class="quantity buttons_added"&gt;     &lt;input value="-" class="minus button is-form" type="button"&gt;    &lt;input class="input-text qty text" step="1" min="1" max="9999" name="quantity" value="1" title="Qty" size="4" pattern="[0-9]*" inputmode="numeric" type="number"&gt;     &lt;input value="+" class="plus button is-form" type="button"&gt;  &lt;/div&gt; &lt;button type="submit" name="add-to-cart" value="267" class="single_add_to_cart_button button alt"&gt;Add to cart&lt;/button&gt;   I am self taught with html and css, but javascript is to foreign for me  I tried the following in CSS but it does nothing.Tried is on codepen and works (i know needs to show instead of hide when checked)....  input[type=checkbox]:checked + .single_add_to_cart_button {     display:none !important;  }
Is there a command prompt  equivalent for Windows 7? That is, I want to filter out the results of a command:  Bash use:  ls | grep root  What would it be from a Windows command prompt? How do I prove or disprove $X \times (Y \cup Z)= (X \times Y) \cup(X\times Z)$  for all sets $X$, $Y$, and $Z$? I'm lost on the steps here. Servlet returns "HTTP Status 404 The requested resource (/servlet) is not available" Take the following two lines of code:  for (int i = 0; i &lt; some_vector.size(); i++) {     //do stuff }   And this:  for (some_iterator = some_vector.begin(); some_iterator != some_vector.end();     some_iterator++) {     //do stuff }   I'm told that the second way is preferred. Why exactly is this? Taking a spin off of this question:  in a new direction for 2014.  Taking into account a basic Windows infrastructure:   domain controllers Exchange 2007/2010/2013 Sharepoint SQL File Servers / Print Servers AD Integrated DNS AD authenticated 3rd party devices (let's say 802.1X for networking and maybe some content-filtering, etc.) AD/LDAP authenticated "administrative" functions on IT apps/hardware/etc. perhaps some KMS stuff throw in a CA if you'd like home grown apps 3rd party in-house apps   Now, let's rip it all out and decide we are going to the cloud.  We've contracted to move Exchange/Sharepoint/File Services to Office 365.  SQL will now be hosted as well on  something like Azure.  We've gotten away from the need for AD-DNS and simply run everything via a simple Windows DNS server.  We still need 802.1X and would like SSO if possible to our various cloud apps.  Home grown and 3rd party in-house apps would likely stay, but have the ability to use internal user databases instead of AD authentication  The question is...do we really need Active Directory at all?  Or more to the point, AD on-premise or even hosted via Azure or similar (ADFS) or running ADDS on a hosted VM through Azure or similar.  Could/Should we look to something else like a 3rd party SSO option such as  or similar that can provide SSO functionality even if it is as simple as LastPass or similar for each user?  What kind of legitimate needs does AD fulfill if everything else in the cloud?  Could a MS-centric infrastructure get away with not having AD at all if they move everything that previously relied on AD to SaaS offerings that didn't rely on AD authentication?

I installed Ubuntu 11.04 on one of my systems and I am using the Unity interface. Unity is working quite well so far but I really miss panel applets for net speed, cpu temp, and system monitor.   These applets are useful for viewing quick info. Unlike 10.10, there is no other way to get this info onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look.  If you know one then please list out any third party indicators with links so that they can be found. Is “are” a borrowed word? I read somewhere that English is the only language to have borrowed a form of its to be verb from another language. I want to say, if memory serves, that it was are that was borrowed from an early Scandinavian language. Is that so?  I know Old English had sind for one of their pronouns inflections of be, the same as in German.  But did it switch to are naturally from some other gentler evolution, or was it borrowed? "PuTTY key format too new" when using ppk file for PuTTY SSH key authentication I wanted to connect to my Unix server using SSH keys.

Can anyone please help me? How do you start Windows 10 in safe mode? When I used listings package to import C# code snippet from within my LaTeX file, I got an output as follows.    At the first line, there is an unnecessary white space because of the BOM (Byte Order Mark) that is intentionally added by Microsoft (R) Visual Studio.  I really want to remove it from the output rather than from the C# file, how to do that?   Here is my LaTeX code:  \documentclass{article} \usepackage{listings,xcolor} \lstset{% language={[Sharp]C}, backgroundcolor=\color{yellow!20}, basicstyle=\tiny, keywordstyle=\color{blue}, identifierstyle=\color{magenta}, breaklines=true}   \begin{document} \lstinputlisting{Program.cs} \end{document} Definition of autocorrelation time (for effective sample size) I've found two definitions in the literature for the autocorrelation time of a weakly stationary time series:  $$ \tau_a = 1+2\sum_{k=1}^\infty \rho_k \quad \text{versus} \quad \tau_b = 1+2\sum_{k=1}^\infty \left|\rho_k\right| $$  where $\rho_k = \frac{\text{Cov}[X_t,X_{t+h}]}{\text{Var}[X_t]}$ is the autocorrelation at lag $k$.    One application of the autocorrelation time is to find the "effective sample size": if you have $n$ observations of a time series, and you know its autocorrelation time $\tau$, then you can pretend that you have  $$ n_\text{eff} = \frac{n}{\tau} $$  independent samples instead of $n$ correlated ones for the purposes of finding the mean.  Estimating $\tau$ from data is non-trivial, but there are a few ways of doing it (see ).  The definition without absolute values, $\tau_a$, seems more common in the literature; but it admits the possibility of $\tau_a&lt;1$.  Using R and the "coda" package:  require(coda) ts.uncorr &lt;- arima.sim(model=list(),n=10000)         # white noise  ts.corr &lt;- arima.sim(model=list(ar=-0.5),n=10000)    # AR(1) effectiveSize(ts.uncorr)                             # Sanity check     # result should be close to 10000 effectiveSize(ts.corr)     # result is in the neighborhood of 30000... ???   The "effectiveSize" function in "coda" uses a definition of the autocorrelation time equivalent to $\tau_a$, above.  There are some other R packages out there that compute effective sample size or autocorrelation time, and all the ones I've tried give results consistent with this:  that an AR(1) process with a negative AR coefficient has more effective samples than the correlated time series.  This seems strange.    Obviously, this can never happen in the $\tau_b$ definition of autocorrelation time.  What is the correct definition of autocorrelation time?  Is there something wrong with my understanding of effective sample sizes?  The $n_\text{eff} &gt; n$ result shown above seems like it must be wrong... what's going on? Does seam itself affect baking? Redirect output from all commands to file, not just last How do I pass a string into subprocess.Popen (using the stdin argument)? Import a python module without the .py extension Topologist's Sine Curve: A rigorous proof of why $\overline{S} = S \cup V$ Let $S$ and $V$ be the following subsets of $\mathbb{R}^2$.  $$ S = \left\{ \ x \times \sin \frac{1}{x} \ \colon  \ 0 &lt; x \leq 1 \ \right\}, \qquad V = \left\{ \ 0 \times y \ \colon \ -1 \leq y \leq 1 \ \right\} = \{ 0 \} \times [-1, 1]. $$ Then how to show rigorously that the closure $\overline{S}$ of $S$ is given by  $$ \overline{S} = S \cup V? $$  By rigorously, I mean using the smme kind of argument as is used in real analysis or topology, such as in (most of) the proofs in Rudin or Munkres.   Intuitively, it is clear that as $x \to 0+0$, then $\sin \frac{1}{x}$ will fluctuate its full range of $[-1, 1]$, and for any point $0 \times y$, where $y \in [-1, 1]$, there will be points of $S$ arbitrarily close to it.   But I'm unable to rigorously show this. So you are camping (please excuse the MMO jargon, sometimes I just can't help myself) your own particular corner of Stack Overflow, hoping for a couple of upvotes before bed.  It's freezing cold and you can't quite drag yourself across the room to grab the little blow heater, because that would mean leaving the almost adequate warmth of your laptop.  A completely objective question pops up, to which you absolutely know the answer.  Riding the surge of adrenaline, you spend the next twenty minutes typing like a madman. Desperate to beat the other lunatics that loiter in your tag of choice.  You beat them to the punch and enter a superlative answer, code samples, examples and maybe some ironic humour. You are flushed with your own awesomeness.  You go to bed. Satisfied you have garnered a couple of points of virtual self validation. You look forward to the flush of pleasure in the morning when you see your account bumped ever closer (yet never close enough) to that shining example of Skeetness.    Yet, the next morning, no such flush occurs.  Your answer sits in prime position for some questioner love and none eventuates.  You might get a couple of upvotes from some sympathetic SO compatriot, but the ultimate (I'll try to avoid any unsavory metaphors here)  satisfaction of accepted answer is denied you.    So my question. How you react to this kind of situation?   Catch yourself monitoring the questioner's account waiting for them to log on and then breaking nearby inanimate objects when your answer continues to be ignored. Panic that the questioner might delete their account, leaving your beloved question to evaporate in a puff of uninterest.  Wondering if it was something you said and answering some other of the questioner's queries in the hope of redeeming yourself in their fickle eyes.   I have seen a few examples of this type of frustration on Twitter and wondered how the hardcore Stack Overflow community dealt with this type of rejection. How do I find out what tool a shortcut is triggering? I used to have problem with connecting two objects, because when I smooth the final object, there was a darker line on the connected parts (for example when I was making head, I've had eyes darker this way). Then I found out that I can get rid of it by hitting Ctrl+N, but I don't realy know what it does. I can just see that the lines are gone. So, what does Ctrl+N do? in elisp's let, how do you reference a variable bound in the same let while binding another variable?
