Is mod_evasive the best prevention to DDOS attack
I am under DDoS. What can I do?
Output to stdout and at the same time grep into a file How to deal with spaces in a variable If banks offer a fixed rate lower than the variable rate, is that an indication interest rates may head down? This is one of the major banks in Australia:   At present time, the variable rate is 7.80% but the fixed rate is 6.99% for one year.  And it seems most banks in Australia, if you fix the rate (at the moment), you will get a lower rate.  Is this an indication that in the eyes of the banks, that they believe the interest rates are going to down? I just ask because it seems most people in the media think the rates are going up and they've risen about 6 times in a row now.  Could it be that the banks are secretly preparing for rates to drop?

Adding a newline before the list item makes the link disappear. What would be a good term for continuous testing post-deployment? I'm thinking of live production sites here, where there is a continuous community or much content being updated, sort of like a newspaper site or community site (the one I work at is a healthcare improvement company) and we have news articles, programs and so on.  While the underlying code is tested and released there are often production issues that come up, maybe certain pages stop working, style sheets suddenly don't appear like they did due to a service patch or some tweak done to improve production security or performance.  There is Acceptance Testing for when a deployment goes out to make sure things work right, Regression Testing to make sure nothing has been broken since previous releases.  Considering we've done these types of tests and things are working fine what would you call testing, or checking, the site to make sure things still work fine?  To be sure new pages are being crawled for search indexing?  To check that newly added pages are using plug-ins correctly?  Or so on.  My manager and I were discussing some issues that have cropped up and decided we needed to do something like this, but then to sort of note it in our status reports we didn't really have a name for it.  Anyone done this and have a term that might be good?  Or would you consider it covered by something like Continuous Acceptance Testing or some such term? Where can I find fantasy minis on the cheap? I'm looking to build a collection of fantasy miniatures, preferably pewter - but I don't want to buy them one at a time from my local hobby store... Much too expensive, and they don't often carry anything I'm interested in buying, which makes it a long term venture as well. So I'm looking for ideas on how to obtain many miniatures at once, preferably for cheap. D&amp;D Miniatures aren't a good source for me as they're collectibles, and the prices on those are also prohibitive.  By the way - they don't have to be pewter, that's just my preference. =) I have an iPhone with 100+ notes that I've collected over the last ten years (thanks to migrating from my PalmPilot). I realize that I can now synchronise these with Gmail, but that doesn't allow me to edit them from my computer. I'd rather switch to use a new app/website combo which allows for online editing of notes, automatic OTA syncing, etc.  It seems like Simplenote and Evernote are two of the better app/sites, as mentioned at  and from this , I think Simplenote is exactly what I'm looking for. The problem is, I can't figure out how to migrate all of my existing notes into whatever new notes app I choose.  How do I migrate my existing Apple iOS Notes into Simplenote or Evernote?  The best workaround I've found so far is to open each note, select all, copy, and create a new note in the iOS app but I'd rather not spend the time and hassle doing this for ~100 notes. Proof the Legendre polynomial $P_n$ has $n$ distinct real zeros Beamer to HTML using make4ht \documentclass{beamer} \usetheme{Madrid} \begin{document} \begin{frame} aaa \end{frame} \begin{frame} bbb \end{frame} \end{document}   The above tex file is to be converted into html. I am using the following command   make4ht filename.tex   However it throws error. The basic question is "Is it possible to convert beamer presentation to html using make4ht?" When working with an image in Photoshop, I'd like to have a simple keyboard shortcut, like in , that automatically does:   Export > Export As or Export > Save For Web  Resize to biggest dimension = 600px (either width or height) Add suffix _600.jpg to filename   How to do that?  I'm not sure how to edit a recorded macro to do that (add the suffix and choose 600px for the biggest dimension).  Example: you open myphoto.png, you press F6 and then you automatically get myphoto_600.jpg. Finding the error in this proof that 1=2 I have a "proof" that has an error in it and my goal is to figure out what this error is. The proof:  If $x = y$, then  $$ \begin{eqnarray} x^2 &amp;=&amp; xy \nonumber \\ x^2 - y^2 &amp;=&amp; xy - y^2 \nonumber \\ (x + y)(x - y) &amp;=&amp; y(x-y) \nonumber \\ x + y &amp;=&amp; y \nonumber \\ 2y &amp;=&amp; y \nonumber \\ 2 &amp;=&amp; 1 \end{eqnarray} $$    My best guess is that the error starts with the line $2y = y$. If we accept that $x + y = y$ is true, then   $$ \begin{eqnarray} x + y &amp;=&amp; y \\ x &amp;=&amp; y - y \\ x &amp;=&amp; y = 0 \end{eqnarray} $$  Did I find the error? If not, am I close?

My array contains about 500 strings and I'd like to create a new Array with the same strings but in a random order.  Please include a C# example in your answer. STI vs STD vs Sexually Transmitted Virus When my phone starts up there are several application/services running in the background that I would rather not.  And when I press the Home button while using an app, that app usually goes into the background without exiting.  How can I stop these apps from running? Tag scores are not updated and the issue is getting worse Convergence of cos, sin, tan functions In Radian mode, continually pressing the $\cos$ function of a number causes the result to converge to $x=0.739085133$, a fixed point of $\cos(x)$. Repeating this behavior with the $\sin$ function causes the result to converge to $x=0$, a fixed point of $\sin(x)$.   What happens if this is done using the tan function? It seems that $x=0$ is a repelling fixed point with no convergence in this case.  What would be the best way to explain these results mathematically? Why AUC =1 even classifier has misclassified half of the samples? I am using a classifier which returns probabilities. To calculate AUC, I am using pROC R-package. The output probabilities from classifier are:  probs=c(0.9865780, 0.9996340, 0.9516880, 0.9337157, 0.9778576, 0.8140116, 0.8971550, 0.8967585, 0.6322902, 0.7497237)   probs shows probability of being in class '1'. As shown, the classifier has classified all of samples in class '1'.  True label vector is:  truel=c(1, 1, 1, 1, 1, 0, 0, 0, 0, 0)   As shown, classifier has misclassified 5 samples. But, AUC is:  pROC::auc(truel, probs) Area under the curve: 1   Could you please explain to me why it happens? Please tell me which choice below (or rather a better choice that I need to know) works better in my sentences in informal English:     I got myself out on a limb. I need to clear my check by tomorrow. No matter how, I must ............ 2 million bucks by tomorrow.   a) line up [to prepare, organize, or arrange something]  b) hook up [hook somebody up with something to help someone get something that they need or want]  c) fix up [to arrange for someone to have something that they need]  For me, all three options work in this sense with the same meaning and informality degree. Why is a deductive closure an intersection of maximally consistent sets? Full Question: Show that if $\Delta(\Gamma)$ is the deductive closure of a consistent $\Gamma$ then $\Delta(\Gamma)$ is the intersection of all maximal consistent sets of formulas $\Lambda$ with $\Gamma \subseteq \Lambda$.  I'm really stuck with this question, I honestly don't know how to even start. Can someone please provide some assistance?
