Obviously I have enough common sense to not add pour water into boiling oil, but after the cooking is done I try to add water to the pan so it's easier to wash. Usually I let it sit there cooling off and more often than not I just forget about it and have the biohazard that is a greasy cast iron ribbed pan to deal with in the morning. If the pan is still somewhat hot and you feel it's warm feel 3-4 inches above the surface of the cookware is it fine to add water? Can it damage the pan in the long run?
Sometimes after I fry something, I wash it immediately in water because it's a bit easier to wash (before the remains stick to the pan).  Does this damage the pan in any way?
Java Round up Any Number Where do files go when you AirDrop them on iOS? Where do AirDrop files go when I transfer them between an iPad, iPhone and iPod? I AirDropped some Google Docs from my iPad to my iPhone but nothing happened; where did my files go? The file was a list of tools. I am using scikit learn  to build a Random Forest classifier.  I have heard that it might be possible to build a single decision tree from a Random  Forest. The suggestion  is that although the decision tree may not be as good a classifier as the Random Forest it may be better than the decision tree you would get by using the standard method.  However I haven't been able to find this method online. Does it exist?     My question is not about extracting one  of the decision trees from a Random Forest. It is asking about a method to construct a new decision tree from the whole Random Forest, perhaps by combining the trees in the Random Forest somehow.

How to get the date in a batch file in a predictable format? In a batch file I need to extract a month, day, year from the date command.  So I used the following, which essentially parses the Date command to extract its sub strings into a variable:  set Day=%Date:~3,2% set Mth=%Date:~0,2% set Yr=%Date:~6,4%   This is all great, but if I deploy this batch file to a machine with a different regional/country settings, it fails because month, day and year are in different locations.   How can I extract month, day and year regardless of the date format? I'm trying to write a script which creates a Nurbs path curve, bevels it, and then stores the location of each vertex/point in that curve. I've been writing it based on the code displayed in the info panel, but it doesn't show what the vertices are supposed to be called - so I can't refer to them in the script.  Update: After following Ratt's links, I modified  for Nurbs Path and am now stuck again, though it's still progress. Below is one version I tried out, but the error message says that Curve has no attribute path_points. Of course it doesn't, because I made that up because I don't know what the Nurbs Path equivalent for bezier_points is.  import bpy import random  def pathPointLoc(cu, typ, points):      for (n) in enumerate(points):         nurb = cu.path_points[n]         print(nurb.location)      return  cu = bpy.data.curves.new("MyCurve", "CURVE") ob = bpy.data.objects.new("MyCurveObject", cu) scn = bpy.context.scene scn.objects.link(ob) scn.objects.active = ob  cu.bevel_object = bpy.data.objects["BezierCircle"] cu.taper_object = bpy.data.objects["BezierCircle"]  pathPointLoc(cu, "NURBS", [(0,0,0,1), (0,0,1,random.randint(1,4)), (0,1,1,1), (1,4,1,1)] ) How does AdamW weight_decay works for L2 regularization? hello I have a question about weight regularization in Adam apparently the weight_decay in the AdamW function  has the same impact as an L2 regularization my questions are: is that parameter the same as lambda that we have in the regularization term?  how does it exactly work? and what is its impact on the model complexity?

Previously, I have installed Windows 7 on my 320 GB laptop with three partitions 173, 84 and 63 GB each. The 63 GB partition was where the Windows was installed. The rest were for file containers.  Now I changed my OS to Ubuntu 12.04 LTS. I installed Ubuntu by replacing the entire Windows 7 on the 63 GB partition. The rest of the partitions remain as an NTFS Windows partition and I can still access them both (the 173 and 84 GB partitions).  Now I want to change the two partitions of Windows into an Ubuntu format partitions plus most importantly, I want to extend the 63 GB partition to more than a 100 GB because at the moment I am running out of disk space. Whenever I try to install any application, especially using wine, it always complains for a shortage of disk space.  How do I do the extending activity before I entirely format my laptop again and lose all the important files on my partitions? What's the difference between an adjective and a past participle? I'm really confused about the object     the doctor specialized will help you   or     the documents required   How can I tell in the future, if I have to use the past participle or the adjective? And what's the name of this structure? I think I have managed to work this out, however there is no solution provided with the question so I thought it best to check.   My working:  Let $(x,y) \in (A \times B) \cup (C \times D)$  $\Rightarrow x \in (A$ or $C)$ and $y \in (B$ or $D)$  $\Rightarrow (x, y) \in (A \cup C) \times (B \cup D)$  $\Rightarrow (A \times B) \cup (C \times D) \subseteq (A \cup C) \times (B \cup D)$  Now let $(x,y) \in (A \cup C) \times (B \cup D)$  $\Rightarrow x \in (A$ or $C) $ and $y \in (B$ or $D)$  $\Rightarrow (x, y ) \in (A \times B) \cup (A \times D) \cup (C \times B) \cup (C \times D)$  $\Rightarrow (A \cup C) \times (B \cup D) \nsubseteq (A \times B) \cup (C \times D)$  $\Rightarrow (A \times B) \cup (C \times D) \not= (A \cup C) \times (B \cup D)$  Is this correct?

Calculation of $\int^{\pi/2}_{0}\cos^{n}(x)\cos (nx)\,dx$, where $n\in \mathbb{N}$ Compute the definite integral      $$ \int^{\pi/2}_{0}\cos^{n}(x)\cos (nx)\,dx $$      where $n\in \mathbb{N}$.   My Attempt:  Using $\cos (x) = \frac{e^{ix}+e^{-ix}}{2}$, we get  $$ \begin{align} \int^{\pi/2}_{0}\cos^{n}(x)\cos (nx)\,dx&amp;=\int_{0}^{\pi/2} \left(\frac{e^{ix}+e^{-ix}}{2}\right)^n\left(\frac{e^{inx}+e^{-inx}}{2}\right)\,dx\\ &amp;= \frac{1}{2^n}\mathrm{Re}\left\{\int_{0}^{\pi/2} \left(e^{ix}+e^{-ix}\right)^n\cdot e^{inx}\,dx\right\}\\ &amp;=\frac{1}{2^n}\mathrm{Re}\left\{\int_{0}^{\pi/2}\left(e^{2ix}+1\right)^n\,dx\right\} \end{align} $$  Letting $z=e^{4ix}$ gives us  $$ \begin{align} e^{4ix}dx &amp;= \frac{1}{4i}dz\\ dx &amp;= \frac{dz}{4iz} \end{align} $$  So the integral becomes  $$\frac{1}{4\cdot 2^n}\mathrm{Re}\left\{\int_{C}\left(\sqrt{z}+1\right)\cdot \frac{dz}{iz}\right\}$$  How can I complete the solution from here? how implement the jqueryUI in visualforce Ill implement the some UI but its not working in the visualpage , can u know how implement jquery ui in viusalpage ,  Kindly tell the procedure ,     Im using this url its not working ,,,,, Boarding a train in India at another station I have booked a ticket on a train from Mumbai to Chennai and boarding at Pune.

The wheel group on *nix computers typically refers to the group with some sort of root-like access. I've heard that on some *nixes it's the group of users with the right to run su, but on Linux that seems to be anyone (although you need the root password, naturally). On Linux distributions I've used it seems to be the group that by default has the right to use sudo; there's an entry in sudoers for them:  %wheel ALL=(ALL) ALL     But that's all tangential; my actual question is: Why is this group called wheel? I've heard miscellaneous explanations for it before, but don't know if any of them are correct. Does anyone know the actual history of the term? Export beamer slides to powerpoint/openoffice-impress/keynote editable format I usually prepare my talks using powerpoint/openoffice-impress/keynote, where I explaing programs, pseudocodes, etc. Recently I was thinking about creating text-only, code-only and pseudocode-only slides with beamer and then exporting them somehow to powerpoint where I modify them to add figures or some minor details for polishing the presentation, which are usually hard to do with beamer. I googled a bit around and found that beamer can export to PDF or PS but not to powerpoint. I wonder anyway if you know some possibility of conversion from beamer to on-screen editable powerpoint/openoffice-impress/keynote. Is there a way to get reverse numbering on the enumerate environment? To build a list of publications, I wish to show the most recent on top of the list, while keeping the numbering similar. This can be achieved manually by doing something like:  \begin{enumerate} \item[42] pub num 42 \item[41] pub num 41 \item[...] \item[1] pub num 1 \end{enumerate}   but is there a more principled approach? Body Diode of a MOSFET So for some MOSFETs, specially with Power MOSFETs, the body diode is a flyback diode that (as far as aI can tell) can be conveniently added to the MOSFET's bulk as there already PN junctions (correct me if I'm wrong).  I've looked at the datasheet of a Power P-MOSFET and it has parameters like "Internal Source Inductance" and "Internal Drain Inductance". So, is the build up of reverse voltage on the source and drain sides, when said MOSFET is suddenly turned off, a behavior intrinsic to (at least some) MOSFETs? Or are these from the rest of the circuit, say inductive loads? Printing reverse of any String without using any predefined function?
