I have rendered a 2 min animation that I'm pretty happy with (my first go with Blender) using models I created. The render was great, noticed a few mistakes so I was going to do some more editing.   I now notice one of the objects has become very noisy, screenshot below. I can't get the texture back. Everything looks fine within Material &amp; Texture in the Properties section of the object. I've even tried to relink the material and UV maps from the object beside it in the screenshot as they are essentially the same object.   Have I just accidentally added noise to the object somehow? To new to Blender to figure it out.  Thanks in advance.
I was following  on creating a watch and noticed that when I rendered the watch, some pieces were messed up.  I'm new to 3D modeling and I've just learned Blender, I can't explain it well, so here's a picture:    Other examples:     I don't know if it's a problem with my World texture, the object, or the object's texture/material, so I can't even guess how to fix it. What causes this? Is it possible to fix it?
Why do I need multiple sites for the same property in Google Webmaster Tools? In researching the best practice for adding sites to the Search Console, I've often seen it suggested to add separate properties for different versions of the same website. Even in  it states:     "Similarly, if your site has http:// and https:// versions, you should   add each as a separate site."   I've seen the same suggested for www/non-www. So if a site is accessible at all the variations of http/s and www/non-www we should have four properties.  But what if the site is only accessible at one variant? i.e. https and www are forced via htaccess, so only  can ever be accessed - should we still add all the variants?   In essence, the problem is that I don't know why Google wants us to do this, so I can't work out if it'll be ok just to have one instance. Is there a keyboard shortcut to "unselect" in Windows Explorer? Reversing Drop Bars If I need to sit more upright on an old Fuji road bike, can I turn the drop handlebars upright and reversed so that they come up and then point to the rear?  I haven't seen anything on the net from anyone who has done that. Assume that a person (not me, I only hold a single citizenship :) has a double citizenship in countries such as the US, Singapore, Australia, Japan, etc, which are eligible for 90/180 visa-free stays in the Schengen area. Could they officially remain in the Schengen area indefinitely by taking a trip to (say) the UK every 89 days? SQL To search the entire MS SQL 2000 database for a value relative polar coordinates for TikZ elements in axis environment I would like to annotate a patch plot with lines whose start and end points are given in absolute polar and relative polar coordinates, respectively.  The patch plot, based on cartesian data, comes out as a circular shape centred around the origin (0,0) and shall be simulated here by a plain circle.  Lines should start at the circumference of the shape and point away from the shape under a given angle and have a well defined length. Therefore, the use of relative polar coordinates for the line's end point.  What seems to be straightforward with TikZ (left) fails inside the axis environment of pgfplots (right): neither the inclination angle nor the length of the line are correct if relative polar coordinates are used.    What is wrong with the rel. polar coordinates here?  The code:  \documentclass{standalone}  \usepackage{pgfplots} \pgfplotsset{compat=1.13}  \begin{document}  \begin{tikzpicture}   \draw(0,0) circle[radius=0.01];   \draw[blue] (0,0) circle[radius=1];   \draw[thick] (45:1) -- ++(45:0.5); \end{tikzpicture}  \begin{tikzpicture}   \begin{axis}[tiny,enlargelimits,   axis equal,   xmin=-2,xmax=2,   ymin=-1,ymax=1,   xtick={-2,-1,0,1,2},   ytick={-2,-1,0,1,2},   grid=major,   ]   \draw[blue] (0,0) circle[radius=1];   \draw[blue, dashdotted] (0,0) -- (45:2);   \draw[thick] (45:1) -- ++(45:0.5); %  \draw[thick] (45:1) -- (45:1.5); %absolute coordinates do work   \end{axis} \end{tikzpicture}  \end{document} I know this sounds kind of ridiculous, but someone stole my mouse from my cubicle.. I came to work in the morning and was about to give my mouse a little shove to wake up the monitor, but it wasn't there!  I'm trying to figure out when this happened. I'm running Windows 7 and it's a USB mouse. I checked the event logs, but there doesn't seem to be any logs that might tell me what I'm looking for.  Is there any place where USB unplug events are logged? Paging SQL Server 2005 Results How do I page results in SQL Server 2005?  I tried it in SQL Server 2000, but there was no reliable way to do this. I'm now wondering if SQL Server 2005 has any built in method?  What I mean by paging is, for example, if I list users by their username, I want to be able to only return the first 10 records, then the next 10 records and so on.  Any help would be much appreciated. Quickly read the last line of a text file? How to modify existing, unpushed commit messages? I wrote the wrong thing in a commit message.  How can I change the message? The commit has not been pushed yet. I would like to insert the below mathematical symbol, it looks like a big Delta but different. Is there command to obtain a similar shape? To be specific, I have an event table that logs when a user joins or leaves a team.  It looks something like the following:  ------------------------------------- | user | event  | team | timestamp | ------------------------------------- | A    | joined | 1    | 2016-1-1  | | B    | joined | 1    | 2016-1-1  | | C    | left   | 1    | 2016-1-1  | | C    | joined | 2    | 2016-1-1  | | A    | left   | 1    | 2016-1-2  | | A    | joined | 2    | 2016-1-2  | | B    | left   | 1    | 2016-1-3  | | A    | left   | 2    | 2016-1-3  | -------------------------------------   I need to restructure this in a view to look something like the following  -------------------------------------- | user | team | joined    | left     | -------------------------------------- | A    | 1    | 2016-1-1  | 2016-1-2 | | A    | 2    | 2016-1-2  | 2016-1-3 | | B    | 1    | 2016-1-1  | 2016-1-3 | | C    | 1    | null      | 2016-1-1 | | C    | 2    | 2016-1-1  | null     | --------------------------------------   How can I achieve this?  For more detail, I'm attempting to do this in Amazon Redshift (PostgreSQL) probability that there is at least one defective part I study economics and I am trying to solve this problem - without success, unfortunately.     A machine has a defect rate of 6%.       a) Chosen at random 4 pieces (with replacement) from the production flow, compute the probability that none is defective.   b) In the event that extractions are performed 60, compute the probability that there is at least one defective part.   I have no idea how to answer the first question. What logical processes can I use?  Regarding the second question, I thought of using the binomial random variable with $n = 60$ and $p = 0.06$. Then:  $$\begin{multline} P (X \geq 1) = 1 - P (X &lt; 1) = 1 - P (X = 0) = \\ = 1 - \binom{60}{0}  \cdot (0.06)^ 0 \cdot (0.94)^{60} = 1 - 0.02446 = 0.97558.\end{multline}$$  Can somebody please explain me how to solve this problem?

Can any one tell me the advantage of synchronized method over synchronized block with an example? Title tag different from title appearing in Google? The 's  feature (E:RftLW, p. 58; WGtE, p. 180) states:     [...] You ignore all class, race, spell, and level requirements on attuning to or using magic items.   Class and race requirements are relatively intuitive, additionally, since an Artificer is able to cast spells they can already attune to items that require you to be a spellcaster. But there's still some questions:   Can they use a spell scroll of a spell not on their spell list? Is this one of the four requirements ignored? What are level and spell requirements; what are some examples? I am just a high school student, and I haven't seen much in mathematics (calculus and abstract algebra).  Mathematics is a system of axioms which you choose yourself for a set of undefined entities, such that those entities satisfy certain basic rules you laid down in the first place on your own.  Now using these laid-down rules and a set of other rules for a subject called logic which was established similarly, you define certain quantities and name them using the undefined entities and then go on to prove certain statements called theorems.  Now what is a proof exactly? Suppose in an exam, I am asked to prove Pythagoras' theorem. Then I prove it using only one certain system of axioms and logic. It isn't proved in all the axiom-systems in which it could possibly hold true, and what stops me from making another set of axioms that have Pythagoras' theorem as an axiom, and then just state in my system/exam "this is an axiom, hence can't be proven".  EDIT : How is the term "wrong" defined in mathematics then ? You can say that proving fermat's last theorem using the number-theory axioms was a difficult task but then it can be taken as an axiom in another set of axioms .  Is mathematics as rigorous and as thought-through as it is believed and expected to be ? It seems to me that there many loopholes in problems as well as the subject in-itself, but there is a false backbone of rigour that seems true until you start questioning the very fundamentals .
