Custom avatars are fetched using http instead of https Stack Overflow  to work through , but the custom avatars (uploaded files, not those from gravatar) are even then fetched from  using standard   (which generates warning in browsers and is not a very good practice). As those images are also available   it could be just a service misconfiguration.  Is there a technical (or any other) reason why they couldn't be fetched using HTTPS?
Better HTTPS support for Stack Exchange sites So it looks like Stack Exchange now supports HTTPS (to some extent). Which is awesome! But there are a few problems, the main one being that some content is delivered over the CDN, which is plain HTTP. This causes browsers to complain about "unsecured content":
I would like to know if it is possible to enable free shipping with Woo Commerce only if certain items (or items of certain categories / shipping classes) are included in the cart.  The Free Shipping option only activates on the basis of cart value or via a coupon code so I investigated Flat Rate shipping and discovered that it prioritises the most expensive shipping class over the cheaper ones. This means the free shipping class I created never overrides the default charge.  I understand the logic behind this but it's the opposite of what I need as the idea is to incentivise purchases of higher profit margin products by eliminating delivery charges when they're included in an order.  I don't know if what I am trying to achieve is simply not possible within Woo Commerce. A coupon that only applies to certain products / categories seems to be the closest I can get but I'd rather not force users to enter a code at checkout.  Does anybody know if there any simpler ways to give users who purchase certain products free shipping? Max dimension of a subspace of singular $n\times n$ matrices I am sure the answer to this is (kind of) well known. I've searched the web and the site for a proof and found nothing, and if this is a duplicate, I'm sorry.  The following question was given in a contest I took part. I had an approach but it didn't solve the problem.     Consider $V$ a linear subspace of the real vector space $\mathcal{M}_n(\Bbb{R})$ ($n\times n$ real entries matrices) such that $V$ contains only singular matrices (i.e matrices with determinant equal to $0$). What is the maximal dimension of $V$?   A quick guess would be $n^2-n$ since if we consider $W$ the set of $n\times n$ real matrices with last line equal to $0$ then this space has dimension $n^2-n$ and it is a linear space of singular matrices.  Now the only thing there is to prove is that if $V$ is a subspace of $\mathcal{M}_n(\Bbb{R})$ of dimension $k &gt; n^2-n$ then $V$ contains a non-singular matrix. The official proof was unsatisfactory for me, because it was a combinatorial one, and seemed to have few things in common with linear algebra. I was hoping for a pure linear algebra proof.  My approach was to search for a permutation matrix in $V$, but I used some 'false theorem' in between, which I am ashamed to post here. I'd like to be able to search for questions by multiple tags; for example "questions tagged 'nhibernate' and 'web-services'".  I can get close by searching for "nhibernate web-services" but the results tend to be a few questions that relate to both terms--but much more largely just questions that relate to one or the other. Exactly half of the elements of $\mathcal{P}(A)$ are odd-sized Let $A$ be a non-empty set and $n$ be the number of elements in $A$, i.e. $n:=|A|$.  I know that the number of elements of the power set of $A$ is $2^n$, i.e.  $|\mathcal{P}(A)|=2^n$.  I came across the fact that exactly half of the elements of $\mathcal{P}(A)$ contain an odd number of elements, and half of them an even number of elements.  Can someone prove this? Or hint at a proof? Installing .pkg with terminal ? Is it possible to install a .pkg using a terminal ? (I wanted to install an app through ssh). How to create an animated Electric Arc or Lightning? I know about the technique of using a displace modifier with an animated displace object on a thin plane, but there are no "branches", no forking in the lightning.  Here is an image  that shows more or less what I'm thinking of:    Is it possible to achieve an 3D animated affect like this?  I have tried a few things, such as the . However, it doesn't support animation and repeatedly generating meshes and then manually animating the visibility is a tedious.

Why GCP Kubernetes Node host location for europe-north1 seems to be in US? Can I purge configuration files after I've removed the package? I was doing a package removal with apt-get remove but then realized I should have done a --purge along with it to remove the configuration files.  Can I remove the packages configuration files easily or do I need to reinstall the package and then remove with a --purge? What are all possible ways to stop a zombie from despawning? Is there any way for which we are able to stop a zombie from de-spawning no matter how far we go? If so, what are all possible ways?  Bonus question: what are all the other techniques for which we can prevent a zombie from de-spawning within a specific block radius? I gave a scammer my telephone number, address, and name. How bad is it? Updated question because old one was embarassing: I saw a spam email from "PayPal" and I didn't realize that it was a phishing attempt. I gave the phishing site my name, telephone number, and email. What could he do with them?  Old question: Well, I saw a spam email, but I didn't realize that it's really a scam at first.

In Outlook, is there a way (or an add-on that can do it) to schedule a recurring out-of-office message?  I work 4 10's, so I'm out of the office every Monday, and it's a bit of a pain to have to reset my out-of-office message every single week. paragraph numbering I am using the paragraph section head, i.e.,   \paragraph{This is a cool paragraph}    I would like it to compile with numbering. If I change the secnumdepth (i.e., \setcounter{secnumdepth}{4}) this will work, but produce the "wrong" type of numbering, i.e.,      1.1.1.1 This is a cool paragraph      1.1.1.2 This is another cool paragraph etc.   What I would like is      1 This is a cool paragraph      2 This is another cool paragraph   or, if not,      1.1 This is a cool paragraph      1.2 This is another cool paragraph   where the first 1 indicates the section number and suppresses the subsection and subsubsection numbers. Can this be done? Is it alright to pay real money for useful help?
