I'm looking into the technique of 'hanging' meat, and whether there are 'home' applications that would be safe and have a beneficial effect.  Now, there are a lot of (possible) synonyms that muddle the waters (for me). There's hanging, dry-aging, faisandage (for game birds), and more. What I'm looking for is the 1-3 day (near) room-temperature storage of meat and the spoiling / enzyme process that will cause a flavor change. Feel free to help me along by clarifying the answer.  Basically:   Is there any (good) use for this technique / process for supermarket / butcher cuts of meat? What should be taken in consideration for safe execution? SQL Server Agent Jobs and Availability Groups I'm looking for best practice in dealing with scheduled SQL Server Agent jobs in SQL Server 2012 availability groups. Maybe I missed something, however at the current state I feel that SQL Server Agent is not really integrated with this great SQL2012 feature.  How can I make a scheduled SQL agent job aware of a node switch?  For example I have a job running on the primary node which loads data each hour. Now if the primary goes down, how can I activate the job on the secondary which now becomes primary?   If I schedule the job always on the secondary it fails because then the secondary is read-only. Navigation bar is too long on progressbar theme, can it wrap? My navigation bar at the top of each slide (that links to each section) has too many sections. I would like to keep the bar and keep each section but I would like to wrap it i.e. have it on two lines.  Is that possible?  I am using compress and I am using  as a theme. using tar showing, "No Such file or directory" But when I try to run it using  tar zxvf jre-8u151-linux-i586   I get tar (child): jre-8u151-linux-i586: Cannot open: No such file or directory tar (child): Error is not recoverable: exiting now tar: Child returned status 2  What is wrong?

Ubuntu 18.04 bond with netplan duplicate MAC address after cloning Auto Increment Problem in Mysql How to access the shared folder between two computers running ubuntu I have to computers running Ubuntu and I want to share files between those computer. these computers are already connected through a cross cable and sharing internet connection using firestarter. Both computers have samba installed.   In Desktop computer I have a shared folder How do I access it on the other one. What are the differences between "su", "sudo -s", "sudo -i", "sudo su"? Determine the convergence of $ \sum_{n=1}^{\infty}\left[1-\cos\left(1 \over n\right)\right] $ I just found this identity but without any proof, could you just give me an hint how I could prove it? $$2^n = \sum\limits_{k=0}^n 2^{-k} \cdot \binom{n+k}{k}$$  I know that $$2^n = \sum\limits_{k=0}^n \binom{n}{k}$$ but that didn't help me 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? Are there any known uncountable transfinite increasing sequences of real numbers? The real numbers are uncountable, so assuming the axiom of choice there is at least transfinite sequence of real numbers $r_0, r_1, r_2, ..., r_\omega, r_{\omega + 1}, ..., $ up to (and possibly including) $r_{\omega_1}$ that contains an uncountable number of terms. However, it's not guaranteed that $r_0 &lt; r_1 &lt; ..., r_\omega &lt; ...$  Is there a known transfinite sequence of real numbers that is monotonically increasing and which contains uncountably many real numbers?

Show to the asker the reasons (but not who voted) given for a vote to close so they can attempt to correct the problem without having to resort to begging for a reopen or reposting an edited version and risk being called a duplicate. One of my friends argues that princessship is the only word which has 3 identical letter comes together (s) ,but I think there is no word such as princessship.  Can anyone tell me whether this is a real word, and if there are any more English words which have 3 letters consecutively? If $\sum_{n=1}^{\infty} a_n$ is absolutely convergent, then $\sum_{n=1}^{\infty} (a_n)^2$ is convergent Let $\sum_{n=1}^{\infty} a_n$ be a series in R. Prove that if $\sum_{n=1}^{\infty} a_n$ is absolutely convergent, then $\sum_{n=1}^{\infty} (a_n)^2$ is convergent. Is copper piping required within a certain distance from a water heater? I have read that National Code requires you to use copper for 18 inches from your water heater.  How can I do this when everything existing is PEX?   I need to replace my existing low boy water heater next to my kitchen sink.  It was installed by the builder ten years ago. All the pipe in the house is PEX.  The existing water heater is connected using PEX as well.    The supply line comes directly thru the wall to the HW Heater. There is no space to run 18 inches of copper! The heater is under the kitchen counter, and the countertop is directly over it. Only about an inch clearance. Ppening an HTML file on localhost in XAMMP/apache 2.2 using subdirectories under htdocs I have a site directory for html (dreamweaver CSS3) with lots of subdirectories that contain HTML files for a number of drop down menus. They work fine where they are, but they all have menus that are JavaScript and could be kept in a separate file. So, I want to use Include. I don't want to have to FTP my files to HostGator every time I want to test the includes. I want to have this on my local machine. So, I am attempting for the first time to setup XAMMP and then run my html files (site) on localhost, so I can see what they look like before ftping everything to HostGator and putting it live.  I tried copying the main site folder to htdocs, and then copying the path to the file I want to run in front of the localhost in Firefox, but it gave me file not found:   Do I have too many subdirectories? Why isn't the file being found? It is there.  Tried this too:   No go. My issue is that I have a blender file in which cameras and lamps do not move when I attempt to rotate them using the mouse. If I select the objects (in object mode), press R, and move the mouse in the viewport, the lamps and cameras don't respond; they remain in the same orientation as when I started, no matter how vigorously I try to move the mouse. The values in the information bar show that the mouse is communicating. If, however, I manually enter a new value for the amount of rotation in the properties shelf of the viewport, the camera moves to the new orientation.  On a new default Blender scene, the cameras and lamps do respond to commands to rotate and scale using the mouse. I've compared all of the settings I can think of, and don't see anything obvious that corrects the problem.   is available. Can there be two distinct, continuous functions that are equal at all rationals? Akhil showed that the  is the same as the continuum, using as a step the observation that continuous functions that agree at rational points must agree everywhere, since the rationals are dense in the reals.  This isn't an obvious step, so why is it true?
