How to Make Multi User Objects Single User?
How do I add newlines between lines printed on the command line? Mail logs are incredibly difficult to read. How could I output a blank line between each line printed on the command line? For example, say I'm grep-ing the log. That way, multiple wrapped lines aren't being confused. Unable to shrink transaction log file in SQL Server I moved to a new company recently wherein they have 2 databases in a SQL server of size 20-25 GB. I'm unable to shrink the log file of the databases. Transaction log backup of the databases are set to run every 30 mins from 6 AM-7PM. They are of size 10 and 2 Gb respectively. I tried to shrink it around 8-9 PM last night but I was not able to do.  The log_reuse_wait column stated it's waiting on a log_backup. I tried taking couple of log backups which didn't help. I ran DBCC OPENTRAN but there are no open transactions.  Also, this morning even after the Tlog backups started at 6:00 AM till now(10:30) it still shows LOG_BACKUP in log_reuse_wait column. And no OPEN TRAN as well.  When I researched on this I found this article from Paul Randal:   It states that if the DB is small and all the content of tlog file is in same VLF it couldn't truncate. I have some 300-400 VLFs in the Databases. So that doesn't make sense here as well.   One thing I noticed that every morning at 6 AM the tlog is a little bigger than the other ones. So I'm thinking to check with the lead DBA to run tlog round the clock. Other than that, I would like to see why is this happening and Am i missing anything.  I tried to shrink with the below command:  Use DB1 go DBCC SHRINKFILE(2,10)  GO   Note: It's SQL 2012 instance running 0n 2012 compatibility A mod-only section of the help center Unable to upgrade Windows 10 edition from Home to Pro I have a Lenovo laptop which upgraded from Windows 8.1 Home to Windows 10 Home.  I have a (legitimate) Windows 10 Pro key which I ran through the "Change Product Key" wizard.  After a reboot I get an error which states "We couldn't upgrade your edition" and asks me to try again or seek help from my system administrator (me!) or Microsoft.  There is nothing in the event logs except Info entries in the Setup log stating it failed to change the installed state to Pro Edition with a hex error code (I don't have access to the laptop right now, I will update later with the full log details)  Googling the hex error code led me to a Windows 7 KB Article regarding Windows Update failure due to locked files. The article stepped through using MSCONFIG to perform a clean boot which I did, but still got the error.  Any pointers on how to upgrade this laptop? Or will I have to get the sledgehammer out and do a clean install?

A certain physics problem I have been working on has turned into a math problem. Particularly, I want to find the solutions of some equation of the form   $$f(x)=ae^{bx}+cx+d = 0$$  where $a, b, c,$ and $d$ are constant, real numbers that come from the physics problem and $x$ will be a real number. I do not know how to find the solutions of an equation of this form. In the special case where $c=0$, the solution is simply  $$x = \frac{\ln(\frac{-d}{a})}{b}$$  but for other values of $c$, I am stumped. If there is no exact form for the roots, is there a relatively simple way to estimate the roots? I made something like this:    I did this with the Ellipse Tool and the Line Tool.  Now the circle is accurate, but the lines inside are very inaccurate. Is there another tool that does the same thing but with a lot more accuracy? Does separation of variables in PDEs give a general solution? When a partial differential equation is solved using the separation of variables method, is the produced solution the most general one that satisfies the equation or have we lost some forms of the solution because of the assumption that it is in the form of separated variables? Intersection of the $p$-sylow and $q$-sylow subgroups of group $G$ Energia/MSP-EXP432 Issue: Analog In Pin removing voltage from Voltage Divider In the circuit below, I want to measure the voltage going to the ADC (output from the voltage divider consisting of a fixed resistor and photoresistor) using an MSP-EXP432; however, the MSP-EXP432 "Analog In" pin is lowering the output voltage (i.e. the voltage going into the ADC from the voltage divider drops when the "Analog In" pin is connected).  I set the analog pin as an input in the code shown below in Energia.  Is there any way to fix this?    const int bitsOfADC = 14; // 14-bit ADC Launchpad //int maxVal = 2^N -1;  // 2^14-1 int maxVal = 16383; float FSV = 5.0; // Supply to 0804ADC float LaunchPadResolution = FSV/maxVal; int D7 = A13; int D6 = A14; int ADCInput = A6; boolean D7_State = LOW; boolean D6_State = LOW; void setup() {   delay(1000);   Serial.begin(9600);   pinMode(D7, INPUT);   pinMode(D6, INPUT);   analogReadResolution(bitsOfADC);   pinMode(ADCInput, INPUT); } Terminal flashes on empty backspace with Yosemite Since using Yosemite, I've had the annoying problem of my current Terminal window flashing when backspacing on an empty line. I know on previous versions of OS X this flashing was not default, and could be toggled in accessibility settings, but I cannot find the same setting and I'm dying to get this turned off. Any known ways to get rid of it? I want a to be rounded to 13.95.  &gt;&gt;&gt; a 13.949999999999999 &gt;&gt;&gt; round(a, 2) 13.949999999999999   The  function does not work the way I expected.

Sam developed an annual sweepstakes promotion entitled “The Free Gas Punt Return Game”.    Do I need a comma after entitled or not? What is the chance that at least two people were born on the same day   of the week if there are 3 people in the room?   I'm wondering if my solution is accurate, as my answer was different than the solution I found:  Probability that there are at least 2 people in the room born on the same day = 1 - (No one was born on the same day) - (Exactly one person was born on the same day)  There are (3 choose 2) different pairs of couples. Each couple has the same birthday as another couple with the chances of 1/7 and different with chances 6/7. Thus:  $$1 – (6/7)^3 – 3(1/7)(6/7)^2 = 0.0553$$  Thanks for any help! LWC Get Pick-list Field Values I am trying to show that if for a group $G$ we have $Z(G)=1$, then $Z(\operatorname{Aut}(G))=1$.  I have tried everything I can think of, but to no avail.  The first part of the problem was to show that $\operatorname{Inn}(G) \triangleleft  \operatorname{Aut}(G)$ - does this have any connection?  I couldn't find one.  I know that $\operatorname{Inn}(G) \cong G/Z(G)$, so in this case $\operatorname{Inn}(G) \cong G$ and $Z(\operatorname{Inn}(G))=1$.  Is there any way to get from this to $Z(\operatorname{Aut}(G))=1$?  How do we go about showing this?  Thanks. Why do objects sometimes fall on their own? I have observed sometimes that when I keep some objects precariously balanced, for e.g. some objects in a cupboard, they seem quite stable at the time when I place them there but after a certain period, maybe even 8 - 12 hours suddenly you hear a noise and you can see that they have fallen for what seems like no apparent reason. What can be the reason for this? obviously, I am looking for a physics explanation and not a supernatural one.
