I have a ecommerce website that sells software and all transactions are secured using PayPal as the payment gateway. Since all transactions are secure using PayPals SSL it doesn't seem worth the time or money to enable it on my site.  Question(s):   Is it worth the extra cost and complexity to enable SSL? How much more does Google reward for HTTPS enabled websites?
First off, sorry for my english. I am currently developing a new website that may be deployed in early 2017. This site may contain user login but that may be shipped later in that year.   Now, I googled about https and I hear mixed opinions, google wants the web in https and may punish those who don't use https in the future. Mozilla will also favor https over http for its Firefox. Let's Encrypt make it for free. So far so good.  What is worrying me is I read that many sites that switched to https suffered much lower revenues of adsense (I read also some terrible things about seo and ranking suffering after switching) and many returned again to http.  How much truth is in the suffering of revenues due to switching to https? My website is still in development so I have actually no links needed to be reindexed. My site isn't a blog type. It mainly provides profiles on local artists in my country.  The problem is I need every penny to cover the server and cdn hosting costs. I can't be sure how much using https will hurt the revenues.
How to load a .NET assembly for reflection operations and subsequently unload it? How do I reset a lost password (using recovery mode requires me to type the password)? Find angle UFO in the picture attached I sent this problem to Presh Talwalkar who suggested me to send it to this site. I tried many things but was not able to find the correct solution.   I made various segments trying to get an equilateral triangle similar to the Russian triangle problem, but no success.  I also tried to flip the triangle UFO over side NO but again no success.   I tried to find like triangles, but not enough.  Could you please give me a hint?   Thanks, R. de Souza The currently proposed Gravitational wave detection apparatus consists of Michelson Interferometer which is supposed to measure distances of the order of $10^{-22}$m. But the wavelength of the light used is in the order of micrometers ($10^{-6}$m). How is this possible? The conventional way to measure distance is by counting the interference fringes. But for path difference smaller than wavelength of laser light this is not possible. Dominoes and induction, or how does induction work? I've never really understood why math induction is supposed to work.  You have these 3 steps:   Prove true for base case (n=0 or 1 or whatever) Assume true for n=k.  Call this the induction hypothesis. Prove true for n=k+1, somewhere using the induction hypothesis in your proof.   In my experience the proof is usually algebraic, and you just manipulate the problem until you get the induction hypothesis to appear.  If you can do that and it works out, then you say the proof holds.  Here's one I just worked out,  Show $\displaystyle\lim_{x\to\infty} \frac{(\ln x)^n}{x} = 0$  So you go:   Use L'Hospital's rule. $\displaystyle\lim_{x\to\infty} \frac{\ln x}{x} = 0$. Since that's $\displaystyle\lim_{x\to\infty} \frac{1}{x} = 0$. Assume true for $n=k$. $\displaystyle\lim_{x\to\infty} \frac{(\ln x)^k}{x} = 0$. Prove true for $n=k+1$.  You get $\displaystyle\lim_{x\to\infty} \frac{(\ln x)^{k+1}}{x} = 0.$   Use L'Hospital again: $\displaystyle\lim_{x\to\infty} \frac{(k+1)(\ln x)^{k}}{x} = 0$.  Then you see the induction hypothesis appear, and you can say this is equal to $0$.  What I'm not comfortable with is this idea that you can just assume something to be true ($n=k$), then based on that assumption, form a proof for $n=k+1$ case.  I don't see how you can use something you've assumed to be true to prove something else to be true. BJT Astable Multivibrator My girlfriend forgot the password for her MacBook (don't ask), so I reset it using the Utilities.  But as you may be aware, this doesn't reset the Keychain password. Her MacBook is now virtually unusable due to Keychain demands continuously provoking a request for the Keychain password.  There are lots of other people asking this around the web and they're usually pointed towards this , which doesn't apply in our situation because the support advice involves entering the old password.  We don't know the old password.  Is it possible to reset Keychain without knowing the old password? We're not bothered about what's in there and what will be lost, we just want the continuous password prompts to go away. After learning about the  datasets I've working with the following layers, from the USA data   Country boundaries State boundaries County boundaries City boundaries ZipCode/Postcode boundaries   What I am trying to find is the equivalent (where appropriate) of the same data for various countries.  Is there any free administrative boundaries available as shapefiles for other countries? I bought a Mac (13", early 2011) almost 5 years ago. When I first got it, it was running under OS X 10.7 and it was pretty fast. I've being upgrading it ever since and it's now running under Mac OS X 10.11.  I guess it didn't totally survive the upgrades because, today, there's a lot of bugs, freezes, lags, "spinning beach ball" appearing,... for example, when I write something on a normal program/editor, the cursor freezes for a few seconds, then catches up to what I'm writting.  As you can guess, that's really annoying! I've been thinkning about upgrading the hardware but I don't know what to do: should I change the RAM to 8 GB - 1 333 MHz (currently my computer has 4 GB - 1 333 MHz)? Or should I upgrade to an SSD (which is pretty expensive and difficult to install)?  Thank you very much. Whenever I add a Quick Smoke effect, I can't preview it on the viewport unless I bake it.   And Yes, I added the Smoke Domain on the object.   I've seen tutorials like this  and this  that clearly shows the possibility of previewing the smoke before baking it.   I'm using Blender on a Mac with AMD GPU. I would guess that this is something related to OpenGL, as thoroughly explained here -  but that's for Windows.   Does anyone have any idea how to fix this? Calculate time elapsed in php - spans over 24 hours How does transvoxel algorithm work and how can I implement It? Frequency dependence of electromagnetic reflection I was surprised to see that the Fresnel equations for reflection depends on refractive index and angle of incidence, but they do not depend on frequency. Why is this case? Are they restricted to regions that do not show frequency dependence? (clickable)  Mainad has a valid height and width, however it isn't shown like subad1/subad2. Which are in essence exactly the same! (just a different background image).  Firebug shows my div as greyed out for some weird reason. Replacing the contents of mainad with just some text doesn't solve the problem (problem isn't related to inner elements)..   What's going on?! :( Can I hire my kid and start a Roth IRA for him? I own an LLC, of which I am currently the sole member. It's my main source of income.  I am wondering if there is a reason why I could not do the following:   Hire my child as a part-time employee of the LLC, for an annual salary of $5500. Start a Roth IRA for the kid and put the $5500 into it. Deduct the $5500 as a payroll expense for my LLC, thereby reducing my amount of taxable income.   To me, this seems attractive because I'd lower my LLC's tax liability. Meanwhile, my kid would not have to pay any taxes on the $5500 because it is lower than the standard deduction. And by putting the money in a Roth IRA, he'd get an investment that would grow tax-free. It would essentially be like getting the pre-tax benefits of a traditional IRA with the post-tax benefits of a Roth.  The way I see it, I'd win, my kid would win and the IRS would lose, for once.  Is there any reason this wouldn't work? There is no minimum age or income for contributing to a Roth IRA. So as long as I could legally hire my kid, I don't see any obstacles. How to use a special character as a normal one in Unix shells? Many questions like 'How to type the double-quote char (")?' are being asked, and we don't want to clutter our community with the same answer (Type it as \" if not enclosed in 's, " if enclosed in 's.) So, the question is here.   You can't type special chars into a terminal like normal ones, e.g. this command will fail:  echo Updates (11)   So, how to type in these chars in the terminal as if they were normal ones?  !#$^&amp;*?[](){}&lt;&gt;~;'"\|&lt;space&gt;&lt;tab&gt;&lt;newline&gt; How can I visualize the file system usage on Windows? High Memory Usage on Linux Server Add UI elements to UIScrollView? So, the question pretty much says it all. I'm on Snow Leopard, and I do a lot of web development, particularly in Rails 3 which makes heavy use of the console.  I've seen some notable bloggers etc. mention Zsh as their preference over Bash, but I don't know what difference it would make.  Could anyone give me a good comparison of what difference there is and what might make one prefer one option or the other?
