Does VB.Net have an equivealent for c#'s yield break?  Public Function Validate(validationContext As ValidationContext)                  As IEnumerable(Of ValidationResult)                  Implements IValidatableObject.Validate     '' what is equivalent to C#'s - yield break; End Function
C# has the keyword called . VB.NET lacks this keyword. How have the Visual Basic programmers gotten around the lack of this keyword? Do they implement they own iterator class?  Or do they try and code to avoid the need of an iterator?  The  keyword does force the compiler to do some coding behind the scenes.  has a good example of that.
Why didn't Count Dooku expose Palpatine? Why didn't Doc remember Marty's outfit? In Back to the Future 3, Doc (from 1955) sends Marty back in time wearing a cowboy outfit.  But then, Doc (from 1885) doesn't remember that it was him who offered this outfit to Marty.   Does this mean there are two different Docs (from differing timelines) or is it the same Doc but he somehow forgot the outfit. How will going from 75% Credit Utilization to 0% Credit Utilization affect my credit score? SQL to find the number of distinct values in a column I can select all the distinct values in a column in the following ways:   SELECT DISTINCT column_name FROM table_name; SELECT column_name FROM table_name GROUP BY column_name;   But how do I get the row count from that query? Is a subquery required? Transform the NFSA with transition table Transform the NFSA with transition table  $$\begin{array}{ccc} X&amp;a&amp;b\\ A&amp;\{\}&amp;\{F\}\\ B&amp;\{\}&amp;\{\}\\ F&amp;\{\}&amp;\{A,S\}\\ S&amp;\{F\}&amp;\{A,F\} \end{array}$$  and starting state $S$ inta a DFSA and give the transition table of that DFSA. Place the letter $X$ (uppercase) in the top left corner of the matrix. Your states in the first column and inputs in the first row can be in the order of your choice.  The question then offers a $7\times 3$ matrix to be filled in.  Unsure how to transform the NFSA with transition table.  This is my answer but it is incorrect.  $$\begin{array}{ccc} X&amp;a&amp;b\\ \{S\}&amp;\{F\}&amp;\{A,F\}\\ \{F\}&amp;\{\}&amp;\{A,S\}\\ \{A\}&amp;\{\}&amp;\{F\}\\ \{A,F\}&amp;\{\}&amp;\{A,F,S\}\\ \{A,S\}&amp;\{F\}&amp;\{A,F\}\\ \{A,F,S\}&amp;\{F\}&amp;\{A,F,S\} \end{array}$$ Is it possible to set a global Blender preference so that all keyframed motion is linear by default? I have a consideration about new off-topic close reason:     Questions asking us to recommend a tool, library or favorite off-site   resource are off-topic for Stack Overflow as they tend to attract   opinionated answers and spam. Instead, describe the problem and what   has been done so far to solve it.   For example take that question:   It has a close vote with the reason above. But if it would be formed     How to zoom image in an absolute position div to the side?   The answer would be probably also a jQuery plugin or javascript library, but it would follow the patter of most questions about jQuery.  Take that question:   This is the good question about real-life problem. The answer is to use a maven plugin. It is correct, there's no need to reinvent the wheel or rediscover the America.   But  I'm afraid the off-topic text could be misleading and could be misused to close such a questions as that about maven simply because a tool, library or plugin is the answer.   Is it a new guideline that the questions such as cited above should be banned, no matter how they are formed (this would make most how-to-do-in-maven/jquery) questions illegal? Or the close reason should be changed to make more clear what the guidelines are (it's not clear to me now)? How to install Ubuntu on portable external Hard Drive? I have updated from Windows 7 Ultimate x64 to Windows 10 Pro x64 using Media Creation Tool.  After some weeks when I'm clicking on the start button nothing happens and the whole status bar becomes unresponsive. After trying to restart explorer.exe from Task Manager explorer.exe fails to initialize. It just shows the start button, Cortana and the search bar, TaskViewer (if that's how it is called) and the Action Centre button.  Any ideas?  I tried running:   sfc /scannow and no errors were found chkdsk /f and no errors were found   A full system restart seems to do the trick but after some time like a few hours it stops responding again.  My configuration:   CPU is Intel i5 4690K OC-d to 4.5Ghz GPU is AMD Radeon HD 7750 Saphire 1Gb GDDR5 Edition   EDIT: After some GOOGLE SEARCHING if i try to run from Task Manager C:\Windows i can actually open a window. The start bar isn't responding though and there are still no desktop icons or wallpaper. Reading a binary file and using Response.BinaryWrite() I have a third-party library which consists mainly of a large number of static (.a) library files.  I can compile this into a single .a library file, but I really need it to be a single .so shared library file.  Is there any way to convert a static .a file into a shared .so file?  Or more generally is there a good way to combine a huge number of static .a files with a few .o object files into a single .so file? Last two digits of $3^{400}$ Equation number in aligned environment after last line I'm using aligned inside align as follows   \documentclass{article} \usepackage{amsmath} \begin{document} \begin{align} x =&22+2 \nonumber\\   =& \begin{aligned}[t]     &5+3\\     &-3+4\\     &+15-0   \end{aligned} \end{align} \end{document}   I want to have just one equation number after the very last line.  However, I'm getting the number at the beginning of the first split line (after the second = ),    and I cannot figure out how to move this equation number to the bottom. Any help will be appreciated. round in PHP shows scientific notation instead of full number I'm trying to do an echo of a variable containing 1400000.  so there is written: echo round(1400000); this gives 1,4E+6 instead of the full number. Anybody an idea on how to display it fully? I have been given a Bode plot of a low pass filter, and tasked with essentially reversing the effects by using a high pass filter. I have solved for the transfer function which is the first equation, and I am assuming the inverse transfer function will give me the information I need to construct the high pass filter. I know the values for \$z\$ and \$p\$. Is there a method given any transfer function to realise the circuit elements required? $$H(s) = 0.17\frac{s-z}{s-p}$$ $$H(s)^{-1} = 5.88\frac{s-p}{s-z}$$ Binary classification with strongly unbalanced classes How and when is old-releases.ubuntu.com updated? I have a device on which I would like to install Ubuntu. How do I find out if Ubuntu will work on it? Let $\{a_n\}$ be defined as follows: $$a_1 = 2, a_{n+1}=\dfrac{1}{3-a_n}$$ $n \geq 1$.   Does $\{a_n\}$  converge?    Using the monotone convergence thereom, if the sequence is both bounded below and decreasing, $\forall n\in\mathbb{N}, n\geq 1$, then we can say the sequence converges.  I'm having trouble proving that the sequence is bounded below by induction.    Claim: The sequence is bounded below by $0$.  Base Case:  $n=1$  $a_1 = 2 \geq 0$, so this holds.  Induction Step  Suppose that $a_k \geq 0$, for some $k \in\mathbb{N}$. (IH)  Prove $a_k \geq 0\to a_{k+1} \geq 0$  I have some difficulty here.  $a_{k}=\dfrac{1}{3-a_{k-1}} \geq 0$  $a_{k+1}=\dfrac{1}{3-a_{k}}$, but we know $a_k \geq 0$, but we don't know how much bigger. It could be that $a_k = 4$, and then I have $a_{k+1}=\dfrac{1}{3-4}$, which is negative, and does not confirm with my claim of being bounded below by $0$. Have I gone somewhere wrong in my induction? I get “signal out of range” displayed on screen after boot up from fresh Ubuntu installation, if flashes grup in corner for half a sec then it goes to “No Input Signal”, anyone got a clue how to get the grub to load in diffrent resolution with out have access to the file system?   if not i guess my only option is to boot from the cd and edit som files to get grub to load in diffrent resolution?   as it is now i cant get access to grub menu, and i cant get access to login screen, all will give me “No Input Signal”, anyone worked around this?
