no space left in '/' but a lot space left in '/home'
How do I free up more space in /boot?
What's the difference between &lt;div class=""&gt; and &lt;div id=""&gt; when it comes to CSS? Is it alright to use &lt;div id=""&gt;?  I see different developers doing this in both ways, and since I'm self taught, I've never really figured it out. Compiling PHP 5.1.6 with PDO MySQL I've got a generic dictionary Dictionary&lt;string, T&gt; that I would like to essentially make a Clone() of ..any suggestions. Am I Running as a Service I am currently writing a little bootstrap code for a service that can be run in the console. It essentially boils down to calling the OnStart() method instead of using the ServiceBase to start and stop the service (because it doesn't run the application if it isn't installed as a service and makes debugging a nightmare).  Right now I am using Debugger.IsAttached to determine if I should use ServiceBase.Run or [service].OnStart, but I know that isn't the best idea because some times end users want to run the service in a console (to see the output etc. realtime).  Any ideas on how I could determine if the Windows service controller started 'me', or if the user started 'me' in the console? Apparantly  is not the answer. I thought about using commandline args, but that seems 'dirty'.  I could always see about a try-catch statement around ServiceBase.Run, but that seems dirty. Edit: Try catch doesn't work.  I have a solution: putting it up here for all the other interested stackers:      public void Run()     {         if (Debugger.IsAttached || Environment.GetCommandLineArgs().Contains&lt;string&gt;("-console"))         {             RunAllServices();         }         else         {             try             {                 string temp = Console.Title;                 ServiceBase.Run((ServiceBase[])ComponentsToRun);             }             catch             {                 RunAllServices();             }         }     } // void Run      private void RunAllServices()     {         foreach (ConsoleService component in ComponentsToRun)         {             component.Start();         }         WaitForCTRLC();         foreach (ConsoleService component in ComponentsToRun)         {             component.Stop();         }     }   EDIT: There was another question on StackOverflow where the guy had problems with the Environment.CurrentDirectory being "C:\Windows\System32" looks like that may be the answer. I will test today. How to find the real user home directory using python? How might a corrupt partition in TempDB result in DBCC CHECKDB reporting no issue?

Apex Array Slice Sometimes I like to use a Queueable to perform work on a list of Ids or sObjects over the heaver Batchable Interface.   However, to do this, we need a very solid implementation of an Array slice method.  Most other programming languages have a native slice method, but Apex does not.  While I have written my own version of slice and it's working fine, I would be interested in hearing about other implementations of slice - the more efficient the better.  My version is in this Utilities class on github   It's modelled after the Javascript version described on the mozilla site   I would expect that the usage and output be similar to this:  String[] arr = ['zero', 'one', 'two', 'three']; String[] sliced = Utilities.slice(arr,1, 3);  System.debug(arr);      // ['zero', 'one', 'two', 'three'] System.debug(sliced);   // ['one', 'two'] Calculation of $\lim_{n\to \infty}\prod_{r=1}^{n} \left(1+\frac{r}{n}\right)^{\frac{1}{n}}$ Calculation of  $\displaystyle \lim_{n\to \infty}\prod_{r=1}^{n} \left(1+\frac{r}{n}\right)^{\frac{1}{n}}$  $\bf{My\; Solution::}$  Let $y=\displaystyle \lim_{n\to \infty}\prod_{r=1}^{n} \left(1+\frac{r}{n}\right)^{\frac{1}{n}}$, Now taking $\log_{e}$ on both side  $\displaystyle \log_{e}(y) = \lim_{n\to \infty}\log_{e}\left(\prod_{r=1}^{n} \left(1+\frac{r}{n}\right)^{\frac{1}{n}}\right)=\lim_{n\to \infty}\frac{1}{n}\cdot \sum_{r=1}^{n}\log\left(1+\frac{r}{n}\right)$  Now Using Reinman Sum of Integral ...  $\displaystyle \log_{e}(y) = \lim_{n\to\infty}\frac{1}{n}\cdot \sum_{r=1}^{n}\log\left(1+\frac{r}{n}\right) = \int_{0}^{1}\ln(1+x)dx = \log_{e}(4)-\log_{e}(e) = \log_{e}\left(\frac{4}{e}\right)$  So $\displaystyle y =\lim_{n\to \infty}\prod_{r=1}^{n} \left(1+\frac{r}{n}\right)^{\frac{1}{n}} =\frac{4}{e}$  But how can i solve above question using Stirling Approximation,  May I ask for help?
