Is there a difference between a LED Backlit and LED HD  Display on laptop monitor? or are they the same that is good for the eyes Can we have the table name as "option" in MySQL? I am very, very new to MYSQL.I tried to create a table named "option". My SQL Query is :  create table option(   id int not null primary key auto_increment,  choice varchar(30)  )  While executing this query it shows the following error  Error Code : 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'option( id int not null primary key auto_increment, choice varchar(30) )' at line 1 (0 ms taken)  If I try with the table name as "choice" it is working.  can we have the table name as "option" in mysql?   thanks I have a bathroom door that is quite loud when operated. And when someone goes to the bathroom at night, it innevatibly wakes someone up (and baby room is just across from the bathroom!) there are 3 components of noise, and I was wondering if there is an alternative to fixing them:   door bangs against the jamb (this is fixed with simple foam bumpers) latch mechanism makes a loud CLUNK when door is pushed closed (I was able to dampen it just a bit by putting foam inside strike plate, but it is still quite loud) lock button also makes a CLUNK when the knob is turned and it is released (this can be battled by replacing with a mechanism that needs to be manually opened [twist instead of push] but it is less convenient, and I would prefer something that automatically unlocks)   Any suggestions as to a knob that has a dampening of the latch and lock button? I have only found one youtube video of my ideal handle, but there is no information on how it works, where to buy it, or anything else: What is this element on the far right of schematic described as "270 OHM"? Is this some kind of inductor? What is its purpose in this device (this is a reference design of dc-dc power supply of sim900 taken from its datasheet) and what would be an exemplary part number? As of today, a  has been found affecting versions 1.0.1 through 1.0.1f (inclusive) and 1.0.2-beta.  Since Ubuntu 12.04, we are all vulnerable to this bug. In order to patch this vulnerability, affected users should update to OpenSSL 1.0.1g.  How can every affected user apply this update now? How do I prove that a graph is a topological manifold I'm having problems with that:  Prove that M is a topological manifold.  $f:U \to \mathbb R^k$, U $\subset \mathbb R^{n}$ open, f continuous  M = $\{\left(x,y\right)\in \mathbb R^{n+k} \mid x \in U, y=f(x) \}$  Can anyone help me please? Why do I get compiler errors with this Java code?  1  public List&lt;? extends Foo&gt; getFoos() 2  { 3    List&lt;? extends Foo&gt; foos = new ArrayList&lt;? extends Foo&gt;(); 4    foos.add(new SubFoo()); 5    return foos; 6  }  Where 'SubFoo' is a concrete class that implements Foo, and Foo is an interface.  Errors I get with this code:   On Line 3: "Cannot instantiate ArrayList&lt;? extends Foo&gt;" On Line 4: "The method add(capture#1-of ? extends Foo) in the type List&lt;capture#1-of ? extends Foo&gt; is not applicable for the arguments (SubFoo)"   Update: Thanks to Jeff C, I can change Line 3 to say "new ArrayList&lt;Foo&gt;();".  But I'm still having the issue with Line 4. What does "had had" mean? How does this differ from "had"? For example, what is the difference between the following two sentences:     I had a bad day      I had had a bad day EXR Transparency Border with bloom and glare was solved by saving to EXR, however when loading that EXR into the VSE over a background a dark border appears around the transparent text that cuts through the glare and bloom.

How can I set up desktop defaults, much like most distributions do, for every new user? (ex. default wallpaper, apps, etc) How to handle client requests to violate copyrights? Let $X$ and $Y$ be finite sets. Then the set $Y^X$ is finite and $\#(Y^X) = (\#Y)^{\#X}$.  I can see how to do it combinatorially. Let $y \in Y$. There are $\#(X)$ choices for such y to come from x, therefore we have $\#Y^{\#X}$ choices. I am not sure how to do it bijectively. TL;DR: how does an Ubuntu flavor iso installation ( for example Lubuntu ) differ from installing a desktop package via apt-get ? (for instance sudo apt-get install lubuntu-desktop)  Context for the question:   Some time ago I answered a question on AskUbuntu , where I tested in virtual machine removing unity-desktop and installing ubuntu-gnome-desktop. That makes the boot logo ( plymouth ) change, desktop changes, different packages get installed (gnome-network-manager instead of network-manager , if I am not mistaken). It appeared that in effect I've switched to different Ubuntu flavor, even though I started out with the standard Ubuntu system. Hence the question: what differentiates the pre-made Ubuntu flavor iso from installing a package ? Is it all the same base underneath the hood or does installation from iso have specific configurations ? If it's possible to install a flavor via package manager, why then separate flavor iso's exist ? (obvious answer is user convenience, but I think there has to exist other reasons. Canonical is a business , and it makes not a lot of sense for a business to provide additional flavor iso , if a sysadmin or end-user can get the same thing via package manager by themselves).

Finding a 2x2 Matrix raised to the power of 1000 Let $A= \pmatrix{1&amp;4\\ 3&amp;2}$. Find $A^{1000}$.  Does this problem have to do with eigenvalues or is there another formula that is specific to 2x2 matrices? Currently, Stack Exchange’s Markdown parser only allows four-space indents to represent code blocks:      // some code     // another line of code    and other Markdown implementations allow for an alternative syntax, that doesn’t require indenting each code line:  ``` // some code // another line of code ```   This is much more convenient to type out. It would be super useful if Stack Exchange could support this syntax.    By extension, this syntax also allow you to specify the source language right after the opening ```:  ```js // some code // another line of code ```   …which would then enable syntax highlighting for that specific language. Although it’s interesting metadata, I don’t think this feature is needed on Stack Overflow, as the syntax highlighting library works pretty well for various languages.  So, even if you would allow this syntax but ignore the ```language, this would greatly improve my productivity on Stack Exchange.  What do you think?  The moderators are currently collecting feedback regarding this feature, so please post a comment with your thoughts. Good idea? Bad idea? Don’t really care? What do you think are the benefits/drawbacks? Experiences? Let them know! Thanks! How to properly scale image in uv editor Hello to anyone who come here and help out or read. I have an issue with the uv editor, I have been trying to make an proper eye. The issue is that I can't figure out how to scale this correctly.    Is there anything I can do to make the eye colors or texture? What are the differences between combat damage, direct damage, and loss of life?
