Hot sauce preserved ingredents I am  in the process of launching a hot sauce business. . but I would life to know what ingredients  to add in it so that it have a longer shelf life ..
How can I modify my hot sauce to make it Shelf Stable? I would like to be able to can and then sell my own hot sauce. The hot sauce I make is a low acid meat (ground beef) and tomato based sauce. I had sent it in to get a shelf life expectancy, and was advised the acidity level was too low and the only way I could make the sauce in a way that it was shelf stable was if I used a retort or sold it as a frozen product. Neither of these are options I can consider at this time.
A tool to measure signal strength of wireless I want to know if there exists any command line option or GUI tool (Ubuntu 11.10) so that I can measure the strength of wireless signal at a given location. I have a house where the wireless is not easily accessible at all corners I want to know at which corners or rooms the signal is weak. Why are there $736$ matrices $M\in \mathcal M_2(\mathbb{Z}_{26})$ for which it holds that $M=M^{-1}$? I'm currently trying to introduce myself to cryptography.  I'm reading about the Hill Cipher currently in the book Applied Abstract Algebra. The Hill Cipher uses an invertible matrix $M$ for encryption and the inverse matrix $M^{-1}$ for decryption. The book recommends to use a matrix $M$ for which it holds that $M=M^{-1}$, since we then have the same key for encryption and decryption.  In the book, they use a $2 \times 2$ matrix $M$ over $\mathbb{Z}_{26}$ as example, and state that for there are 736 $2 \times 2$ matrices for which it hold that $M=M^{-1}$.  I'm trying to pick up on as much as possible when reading things, since I find it counter-productive for learning to skip something, when you don't get the theory behind it. Can someone enlighten to me, as to why it is that there are 736 possible $2 \times 2$ $M=M^{-1}$ matrices and how to find them?

How add 14 days on end date I have End Date column and I want to add 14 Days on it auto when created, can I do it by workflow? Can I do it via jQuery. If yes how? if no how I can do it? Universal type tranformer in Haskell Where did the Q come from, before the Q Continuum? In the Star Trek Universe where did the Q come from? I mean before they were Q in the Q Continuum? In Star Trek Voyager you learn that the race is somewhat intolerant of individualism (in the episode of the Q Civil War) but Q also suggest they have always been Q. Is that statement true, have the Q always been the Q? or were they a race that evolved into omniscience? I have Ubuntu 14.04 installed on my laptop. Can I clone the entire system with apps, settings, etc on a USB 3 pendrive, and then boot from that on other computers as a portable Ubuntu installation to take around with me?  I am trying a function that Timeshift has that's called "Clone the current system on another device". I've selected the pendrive as the target device. Timeshift was talking about this being bootable. But is it going to bootable on only this laptop, or on any system? For example, on an Intel Mac, or a Windows computer without the grub bootloader? Is that Timeshift function what I am looking for, or do I have to do something else?  Edit: The Timeshift clone failed to boot on the first system I tested it on. (A Dell Hackintosh that usually boots from USB just fine.) I need to create a request for a web page delivered to our web sites, but I need to be able to set the host header information too.  I have tried this using HttpWebRequest, but the Header information is read only (Or at least the Host part of it is).  I need to do this because we want to perform the initial request for a page before the user can.  We have 10 web server which are load balanced, so we need to request the file from each of the web servers.    I have tried the following:  HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://192.168.1.5/filename.htm"); request.Headers.Set("Host", "www.mywebsite.com"); WebResponse response = request.GetResponse();   Obviously this does not work, as I can't update the header, and I don't know if this is indeed the right way to do it. Different methods to compute $\sum\limits_{k=1}^\infty \frac{1}{k^2}$ (Basel problem) To be honest I'm not sure how to run LAStools from within QGIS 2.8. I'm trying to learn by experimentation.  QGIS shows all the LAStools in the toolbox  If I double click on a LAStool in the toolbox I get the following message:     Missing dependency. This algorithm cannot run :-(   LAStools folder is not configured. Please configure it before running LAStools algorithms.   I can't find any LAStools *.exe files anywhere within my QGIS Wien file structure.  That makes me wonder how I could have LAStools show in the toolbox.  Could it be a *.dll somewhere?  What am I doing wrong?

The user on the last thread suggested I use except, but I couldn't get it working.

No connection could be made because the target machine actively refused it (PHP / WAMP) Physics are not simulated past a certain frame? I've set up the physics of a swinging wrecking ball and set the animation to run for 240 frames.  This was not long enough for the entire "swing" of the ball-and-chain.   I'm unable to reset the timeline, but I can set the end frame to (say) 1000 frames, but when I try to play the animation, the animation progress halts at frame 240 and I cannot get it to go any further.   There are no markers or keyframes in the timeline.  What should I do to "force reset" the animation-timeline, to allow changes to the length? Sufficient Identification for Intra Schengen flights If one takes a direct flight from one Schengen member state to another, what's the minimum sufficient ID that needs to be provided to board the flight? By taking courses, I have learned topic A. Through self-studying and discussion with others, I have explored topic B.    I also study topic A outside the classroom. What I want to emphasis is that topic B is not in my curriculum, but I study it on my own. Extracurricular activities can include both activities contributed to academic study although outside the normal curriculum, but also activities not contributed to academic study such as sports, volunteer work, etc. I want to emphasis the former activities. Do you say "outside classes", when mentioning study by yourself, i.e.      Outside classes, I have explored B.      If it were you, how would you rewrite the first quote for the same       meaning?    Thanks! I am building a drupal site using Views, search API module and user-points module.  I created the "database server", and indexed many fields of nodes.  I created a search page using views and the search API, that present content (image, title etc.) In addition, I want to add to every content in this search view the name of the author that wrote it, his author picture.  I add the Indexed Content: Author relationship. Unfortunately, I can't find a way to add the author picture and the current total point to my view.  Can somebody advice how to do that?
