Irreducible Components of the Prime Spectrum of a Quotient Ring and Primary Decomposition Why getting this error tlmgr Unknown directive? I haven't used tlmgr for a while but when I tried to install any package with it today, It returned following message:     (running on Debian, switching to user mode!)

I've tried to use fix specified on :     You have to download update-tlmgr-latest.sh from the tlpretest repository   and run it. Afterwards you will be able to work with tlmgr as usual   (announced by Norbert a few hours ago).   I've downloaded it from , but it returned another error:  Verifying archive integrity... All good.

Paging using ldapsearch I am searching an LDAP directory that has a much larger number of results than the sizelimit currently set,500, by slapd.conf that for all intents and purposes cannot be changed)  My idea was to keep running ldapsearch but from a different offset each time (501, 1001, etc.) until all results have been obtained.  I have seen the , and it appears that this is handled for you using the -E options:  -E [!]&lt;ext&gt;[=&lt;extparam&gt;] search extensions (! indicates criticality)          [!]domainScope              (domain scope)          [!]mv=&lt;filter&gt;              (matched values filter)          [!]pr=&lt;size&gt;[/prompt|noprompt]   (paged results/prompt)          [!]subentries[=true|false]  (subentries)          [!]sync=ro[/&lt;cookie&gt;]            (LDAP Sync refreshOnly)                  rp[/&lt;cookie&gt;][/&lt;slimit&gt;] (LDAP Sync refreshAndPersist)   So i tried: ldapsearch -h $HOST -p $PORT -x -L -b "$BASE" '*' '+' -E pr=$SIZE  However when the results (even paged results with size = 50 for example) hit 500, I get the same error as if the results were not paged:  Size limit exceeded (4)  I have seen in the man pages there is another option for virtuallistview but have been unable to find examples for it, and as well I dont think my version of ldapsearch has this option.  The goal here is to create a backup using ldapsearch and the -L option to create an ldif file that is suitable for restoring the database.  A few google searches show up with the same problem I'm having, but none have an applicable solution.. What is the CVE-2014-6271 bash vulnerability (Shellshock) and how do I fix it?

Enumerated description list How can a list be created, whose items are both    enumerated (a,b,c,d,...)  and allow for setting a description via \item[texthere] ?   Im am using MikTex on Windows. I have a very strange behavior on an Android device (Nexus 7) when trying to access local network applications. Instead of getting the actual IP of the machine on LAN, the Android device gets the public IP, which means that Chrome, Firefox or any other browser simply shows the web page of the router.  I have an internal DNS server which handles the local networks. Doing ping from a PC works correctly:  $ ping s.pelicandd.com  PING pelicandd.com (192.168.1.15) 56(84) bytes of data. 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=1 ttl=64 time=0.524 ms 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=2 ttl=64 time=0.578 ms ^C   On an HTC One device (accessed with adb shell), it works well too:  shell@m7:/ $ ping s.pelicandd.com  PING pelicandd.com (192.168.1.15) 56(84) bytes of data. 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=1 ttl=64 time=2.56 ms 64 bytes from front.pelicandd.com (192.168.1.15): icmp_seq=2 ttl=64 time=27.8 ms ^C   However, this is what I get when doing the same ping from Nexus 7:  shell@flo:/ $ ping s.pelicandd.com  PING pelicandd.com (90.78.26.42) 56(84) bytes of data. 64 bytes from LFbn-1-2441-42.w90-78.abo.wanadoo.fr (90.78.26.42): icmp_seq=1 ttl=64 time=2.56 ms 64 bytes from LFbn-1-2441-42.w90-78.abo.wanadoo.fr (90.78.26.42): icmp_seq=2 ttl=64 time=8.63 ms ^C   Instead of resolving to the internal IP, it resolves to the public one.  The network configuration is—except the IP address of the device—exactly the same on both devices: IP settings are set to Static, and DNS servers are the internal ones. Both Android devices are connected through Wi-Fi (unlike the PC). A major difference, however, is that Nexus 7 is using Android 6.0.1, while HTC One uses Android 5.0.2.  There is no nm-tool, dig or nslookup on Nexus 7. The device is not rooted.  The problem existed since I bought the device a few weeks ago, so it could hardly be the issue with DNS cache.  What can I do to further inspect this issue? $A_n$ is the only subgroup of $S_n$ of index $2$. I have to use a particular web site for work, but this web site checks to see whether I'm using Internet Explorer and, if not, won't allow me to log in.  I can switch my User-Agent header using the  Firefox plugin and the web site works fine, but I really don't want to switch the header every time I go to the site and also don't want my User-Agent header to perpetually say I'm using IE.  I'm on Linux, so actually switching to IE unfortunately isn't an option.  Is there any way to define a particular User-Agent for a particular web site in either Firefox or Chrome? If $A$ is a non-square matrix with orthonormal columns, what is $A^+$? If a matrix has orthonormal columns, they must be linearly independent, so $A^+ = (A^T A)^{−1} A^T$ . Also, the fact that its columns are orthonormal gives $A^T A = I$. Therefore,  $$A^+ = (A^T A)^{−1} A^T = (I)^{-1}A^T = A^T$$  Thus, $A^+ = A^T$. Am I correct? Thank you.

Random plot based on a specific random seed Adding materials to more than one object Alternate moves, first one to roll a 6 wins: what's the probability of winning? Question: Players A and B play a sequence of independent games. Player A starts and throws a fair die and wins on a "six". If she fails then player B throws the same die and wins on a "six" or fails otherwise. If she fails then player A gets the die and throws again, and so on. The first player to throw a "six" wins. Find the probability that player A wins.  Here is what I have done:  A wins right away: $\dfrac{1}{6}$  A fails B wins: $\dfrac{5}{6}\times \dfrac{1}{6}$  A fails B fails A wins: $\dfrac{5}{6}\times \dfrac{5}{6}\times \dfrac{1}{6}$  Unlike another similar question which the player B can win on "five" and "six" after player A fails on the first throw, in this case, the games do not seem to have an endpoint. How should I calculate the probability that player A wins then? Why do we have no enzyme to digest cellulose? As we know, cellulose is the most abundant polysaccharide in nature.
