I like using option strict, for the "discipline" it forces upon you. However there are a few cases, you just don't find any option strict compatible code. For example when you use WScript, I know no way but a CreateObject ... Is there a way to "disable" option strict on a few lines?
Is there a way to turn option strict off for just a single line of code?    I'm doing some maintenance work and I need to "cheat" in just one place and I don't want to lower the standard for the entire file.
How do I gunzip all files recursively in a target directory? I'd like to know what is the command to use to gunzip all files in a target directory recursively? I tried to use the unzip command but it didn't work.  I tried the command from My attempt at value initialization is interpreted as a function declaration, and why doesn't A a(()); solve it? In the review page, it shows stats of recent reviewers. But it is showing wrong stats. Because today (on Monday) it shows week count 53 (on Meta Stack Overflow) which is impossible as there is a limit of 20 reviews per day.    PS: This bug   and . But the bug has occurred again. Is every complex (smooth) manifold a scheme? The question in the title doesn't quite make sense. I was always wondering if the scheme is the generalization of manifold. The precise statement should be like following:  If $X$ is a complex (smooth)manifold, is there a scheme $Y$ over $\mathbb{C}$ such that the corresponding analytic space $Y^{an}$ isomorphic to $X$?  I guess if $X$ is projective, then this is Chow's theorem. And I doubt the question has an affirmative answer if $X$ is non-compact (I guess that $X: y-e^x=0$ in $\mathbb{C}^2$ might be an example, but I do not know how to show this).  Edit 1:  There are also example (as @hunter pointed out) of a complex torus but not an abelian variety shows that a compact manifold might not be a variety, however, is it possible to be a scheme ?(according to Hartshorne, the category of varieties is a subcategory of quasi-projective, integral, separated scheme. But could there be some non-quasiprojective scheme($Y$ has to be integral, separated in our case according to GAGA, I guess) )?  Edit 2: Another question I think of is: is (Artin) Stack a generalization of manifold? I really want to know if manifold could be think of some subcategory of some category of with "algebraic objects". Schengen Visa Refusal: Justification for the purpose and conditions of the intended stay was not reliable Schengen refusal formulae can be difficult to understand sometimes.  Sometimes an applicant receives a refusal with:       Justification for the purpose and conditions of the intended stay was not reliable.     often accompanied by:       Your intention to leave the territory of the Member States before the expiry of the visa applied for could not be ascertained.   What is meant by this refusal reason?  What are they trying to say? old Designjet 430 with Windows 10 E: Unable to correct problems, you have held broken packages create a .deb Package from scripts or binaries I searched for a simple way to create .deb Packages for things which have no source code to compile (configs, shellscripts, proprietary software). This was quite a problem because most of the package tutorials are assuming you have a source tarball you want to compile. Then I've found  short tutorial (german).  Afterwards, I created a small script to create a simple repository. Like this:  rm /export/my-repository/repository/* cd /home/tdeutsch/deb-pkg for i in $(ls | grep my); do dpkg -b ./$i /export/my-repository/repository/$i.deb; done cd /export/avanon-repository/repository gpg --armor --export "My Package Signing Key" &gt; PublicKey apt-ftparchive packages ./ | gzip &gt; Packages.gz apt-ftparchive packages ./ &gt; Packages apt-ftparchive release ./ &gt; /tmp/Release.tmp; mv /tmp/Release.tmp Release gpg --output Release.gpg -ba Release   I added the key to the apt keyring and included the source like this:  deb http://my.default.com/my-repository/ ./   It looks like the repo itself is working well (I ran into some problems, to fix them I needed to add the Packages twice and make the temp-file workaround for the Release file). I also put some downloaded .deb into the repo, it looks like they are also working without problems. But my self created packages didn't... Wenn i do sudo apt-get update, they are causing errors like this:  E: Problem parsing dependency Depends E: Error occurred while processing my-printerconf (NewVersion2) E: Problem with MergeList /var/lib/apt/lists/my.default.com_my-repository_._Packages E: The package lists or status file could not be parsed or opened.   Has anyone an idea what I did wrong?  UPDATE 2012-03-06: Just a a hint for another person who is searching for a easy way to create DEBs: Take a look at . Problem:  $F = \frac{(G m_1 m_2)}{r^2}$  An object of unknown mass is placed directly between the Earth and the Moon such that the forces of gravity acting on the object are equal from both the Earth and the Moon. The distance from the Moon to the object is exactly one-tenth of the distance from the Moon to Earth. Using the above formula, determine the distance from the Moon to the Earth.  Given is:  The factor $G≈6.67∙10−11\mathbf{N(\frac{m^2}{kg^2})}$ is a universal constant.  Mass of Earth $≈5.972∙10^{24}\mathbf{kg}$   Mass of the Moon as $≈7.348∙10^{22}\mathbf{kg}$  Mass of unknown object = $m$  My solution:  $F = \frac{(6.67 *10^-11) m (7.348*10^{24})}{R^2}$  $F = \frac{(6.67 *10^-11) (5.92* 10^22) m}{10R^2}$  As gravitational force acting on the object is equal   $\frac{(5.92\cdot 10^22)}{100r^2} = \frac{(7.348*10^{24})}{r^2}$  $R = 1.24 \cdot 10^4 KM$  Is this a viable solution to the problem? Please provide feedback. Thank you! Basic Excel currency format with Apache POI I'm able to get cells to format as Dates, but I've been unable to get cells to format as currency... Anyone have an example of how to create a style to get this to work?  My code below show the styles I'm creating... the styleDateFormat works like a champ while styleCurrencyFormat has no affect on the cell.  private HSSFWorkbook wb; private HSSFCellStyle styleDateFormat = null; private HSSFCellStyle styleCurrencyFormat = null;   ......  public CouponicsReportBean(){     wb = new HSSFWorkbook();     InitializeFonts();  }  public void InitializeFonts() {     styleDateFormat = wb.createCellStyle();     styleDateFormat.setDataFormat(HSSFDataFormat.getBuiltinFormat("m/d/yy"));       styleCurrencyFormat = wb.createCellStyle();     styleCurrencyFormat.setDataFormat(HSSFDataFormat.getBuiltinFormat("$#,##0.00"));  } I am having Problems converting user rights.

Taking the second derivative of a parametric curve I understand that for the parametric equations  $$\begin{align*}x&amp;=f(t)\\   y&amp;=g(t)\end{align*}$$  If $F(x)$ is the function with parameter removed then $\displaystyle F&#39;(x) = \frac{\text{d}y}{\text{d}t}\big/\frac{\text{d}x}{\text{d}t}$  But the procedure for taking the second derivative is just described as " replace $y$ with dy/dx " to get   $$\frac{\text{d}^2y}{\text{d}x^2}=\frac{\text{d}}{\text{d}x}\left(\frac{\text{d}y}{\text{d}x}\right)=\frac{\left[\frac{\text{d}}{\text{d}t}\left(\frac{\text{d}y}{\text{d}t}\right)\right]}{\left(\frac{\text{d}x}{\text{d}t}\right)}$$  I don't understand the justification for this step. Not at all.   But that's all my book says on the matter then it launches in to plugging things in to this formula, and it seems to work well enough, but I don't know why.  I often find answers about question on differentials are beyond my level, I'd really like to get this, it'd mean a lot to me if someone could break it down. Is there an easy way to show which spheres can be Lie groups? Seem to have lost 4 Silver badges and 10 Bronze badges I've already done a lot of searching (in particular: ) to try to prove this statement:      $f: A \to B$ is injective if and only if it has a left inverse. [I'm going to also assume $A$ and $B$ are nonempty.]   My attempt so far:     $\Leftarrow$ Suppose $f$ has a left inverse and $f(a_1) = f(a_2)$ for    $a_1, a_2 \in A$. Then there is a function $g: B \to A$ such that   $g\left(f(a_1)\right) = a_1$ and $g\left(f(a_2)\right) = a_2$. Since   $g$ is well-defined, it follows that $g\left(f(a_1)\right) =  g\left(f(a_2)\right)$, and hence $a_1 = a_2$.         $\Rightarrow$Now   suppose $f$ is injective. Then $f(a_1) = f(a_2) \implies a_1 = a_2$.   Furthermore, since $A$ is nonempty, there is an element $x \in A$.   Define $g: B \to A$ by  \begin{equation*} g(b) = \begin{cases}  f^{-1}(b), &amp; b \in \text{Im}(f) \\ x, &amp; b \in A \setminus  \text{Im}(f)\text{.} \end{cases} \end{equation*} This mapping is   well-defined, since if $f$ is injective, $f^{-1}(b)$ is unique.   My main question: does this imply that if $f: A \to B$ is injective that any mapping $g: \text{Im}(f) \to A$ is bijective? Otherwise, I don't understand why we can even use $f^{-1}$ on an element. [Please read the link above for more details - in proof 1.] Are there integer solutions to $9^x - 8^y = 1$? Science Fiction novel or novels about starship that becomes a god, colonizes hostile planet Plot Summary/Details  The sharpest memory I have of this one is that it was unusually dense reading. Much more difficult going than most of the sci-fi stuff I'd read by that time (I was 10 or 11, I think).  What I remember in terms of plot is that there is a starship, sent either to explore, or colonize, a distant star system.  I don't remember the names of any of the characters, but I think maybe they discover they are clones?  In any case, something happens to the computer system that the onboard AI becomes sentient and develops a measure of omniscience and omnipotence.  It effectively becomes a god of sorts.  The next part I can remember, and I'm not sure this is the same book or not, is that the ship has forcibly settled the crew on a hostile planet.  All sorts of nasty indigenous life forms live here, and guards are post on the wall outside the settlement to destroy them as they try to enter.  I remember there is a female character standing watch, and she goes over the bestiary in her mind.  One particularly nasty creature paralyzes you, and then burrows up your spine into your brain (or something like that) if it gets a hold of you.  That's all I can recall.  Not a lot of detail, unfortunately, but I'm having a tough time remembering much about this one.  I never finished the book(s), as they were mostly "over my head" at that age. We walk or ride on our vehicles to our destinations daily. Does our movement have any effect on the rotation of the earth according to Newton's law? What will be the effect if we move all the peoples along with their vehicles at their maximum velocity in one line in one direction along the equator? How much effect will it make? If moderators can view , can we see comments we've deleted? We can see our deleted answers, but why not our deleted comments? Cancel/kill window.setTimeout() before it happens I have a few places where I use the line below to clear out a status, for example.  I have a few of these that hang out for 10 seconds or more and if the user gets clicking around the action can occur at incorrect time intervals.  window.setTimeout(function() { removeStatusIndicator(); }, statusTimeout);   Is it possible to cancel or kill this with some jQuery or JavaScript code, so I don't have this process hanging around?
