When viewing youtube videos, video is distorted like this:    Flash player is up to date, javascript is enabled, and same issue for firefox and chromium browsers. What to do?
I recently installed Lubuntu but I have a problem with Adobe Flash Player. I always see something that looks like this when I open a video:    (source: )    The video is small, grainy, and is green and purple.  I tried to reinstall Flash and to test it in multiple browsers without success. I installed an older version of Flash but no result.

How to install specific Ubuntu packages, with exact version? I want to setup a new virtual machine with some specified packages (name and version), that are provided.  For example apache2 in version 2.2.20-1ubuntu1 with all dependencies. Even if there is a new version of this package on the servers this one should be installed.  The solution has to work/scale with multiple (n) "setups". Another virtual machine might need an older version of apache2.  I currently know of some possibilities that install the exact packages, but do not scale that good:   Copy all required *.deb to every virtual machine manually and enter: dpkg -i ... -> Could work, but it is very error prone. (Manual scripts etc.) Create and use a new Ubuntu repository for each setup. -> Does not work because I would need n repositories. Setup the machine once and copy the VM / create a snapshot. -> Does not work because I would need to store n VMs.   My problem could be labeled as patch management, but I do not want to update my packages to the current version. My goal is to install old packages. Natbib puts reference data one line per item I'm using:  \documentclass[oneside,article,openbib,12pt,titlepage]{memoir} \usepackage[authoryear,round]{natbib} % Better bibliography support \bibpunct{(}{)}{,}{a}{,}{,}   in the preamble of my document and  \backmatter \renewcommand{\bibname}{References} \bibliographystyle{chicago}    \bibliography{listb,mybib}   in the body of the file. But a typical formatted reference is:     Freely, I. (1997).   A small paper.   The journal of small papers -1. to appear.   I've tried other non-natbib styles (e.g., regstud), and the reference flows and wraps as it should. So how does one get natbib to do the same?  Also, how does one get natbib to include the authors' entire first names? unable to use synaptic via launcher When I open synaptic via launcher on gnome-panel, it opens and asks me for the password but if I enter the password, it says its wrong even though the password is correct and it used to work OK few days ago. If I open synaptic via terminal using sudo synaptic then it opens OK without any problem. Let's consider it case by case:  Case 1: Charged particle is at rest. It has an electric field around it. No problem. That is its property.  Case 2: Charged particle started moving (it's accelerating). We were told that it starts radiating EM radiation. Why? What happened to it? What made it do this?  Follow up question: Suppose a charged particle is placed in uniform electric field. It accelerates because of electric force it experiences. Then work done by the electric field should not be equal to change in its kinetic energy, right? It should be equal to change in K.E + energy it has radiated in the form of EM Waves. But then, why don't we take energy radiated into consideration when solving problems? (I'm tutoring grade 12 students. I never encountered a problem in which energy radiated is considered.)

Compare two objects in Java with possible null values Canonical Question  I want to do &lt;some really cool thing&gt; with a lightning:datatable, but I can't seem to figure out how to do it. I checked the , but I did not see a way to implement &lt;this really cool feature I need&gt;.  Perhaps I want to provide tooltips, or a pick list, or alter the behavior of the menus, or display images, or show a custom component I created, or define a new row-level click behavior, or alter the keyboard event handlers, etc.  Can I somehow do this? Beamer how to change color of infolines and frame title How could I change the color of color of infolines and frame title in beamer. I am using this now   \documentclass[xcolor=dvipsnames]{beamer} \usetheme{CambridgeUS} \useinnertheme{rectangles} \useoutertheme{infolines} \usecolortheme[named=Brown]{structure}    I need to change the color from red to brown. [named=Brown] doesn't work for \useoutertheme{infolines}. This is my current output. I also need to change the background of frame title (mouse pointer) Render turns out plain white For some reason, when I render out the image, it is plain white. I've checked the sky settings, and I tried applying textures, but nothing seems to change.  How can I fix this? EXTRA PROBLEM I have NEI on minecraft with some other mods and NEI is supposed to have a saves thing on the left, and items on the right. The only thing on the left is the options. I want to see the saves and time changing options too.  Cheat Mode When I click on a item to get it it keeps showing me the recipe. Though in the options menu from NEI it is on cheatmode. I saw another post saying I need to change something to this lockmode=-1 or cheatmode=2 but it is already that way. That didn't work how do i get it to give me the items and also recipe when I press R. Why does my Task Manager window outline keep disappearing? Possible Duplicate:          I'm not sure what the proper term for the window outline is (chrome, I think?), but it keeps disappearing.    As you can see, theres no File->Exit or buttons that allow me to minimize or close this dialog. So instead it stays on top of everything else (unless I 'Switch To' another window). There is also no Processes tab or anything.  Since you cant right click the toolbar or bring up another instance of Task Manager, the only way to actually kill this dialog seems to be restarting. However the next time I bring up Task Manager, it will still refuse to go away.  Anyone know whats going on? I'm running 32-bit Vista SP1. My ESTA approval if I have previously had a B1 refusal I applied for a B1 visa to attend a conference in the USA in 2013. I had another nationality (Non- VWP) at the time and my B1 application rejected under section 306 of border security. I now can apply for ESTA under my new nationality. Can my ESTA application get approved? If not and I need to apply for visa is it every time I need to travel to stated or is it just the first time? Regarding the ellipsoid computed by using the "lifting step" I need your expertise in understanding and hopefully solving the following problem:  Let $C \subset \mathbb{R}^d$, and lets assume that $C$ is not centrally symmetric, thus when computing the $MVEE(C)$ (i.e the minimum volume enclosing ellipsoid), they use the following "lifting step":  $$ C^\prime = \left\lbrace \pm \begin{bmatrix} x\\ 1 \end{bmatrix} \middle| x \in C \right\rbrace,$$ where $C^\prime$ is centrally symmetric.  It is proven that for any $\varepsilon &gt; 0$, $MVEE(C^\prime) \cap \Pi$ is a $(1 + \varepsilon)$-approximation to $MVEE(C) \times \left\lbrace 1 \right\rbrace$, where $\Pi = \left\lbrace x \in \mathbb{R^{d+1}} \middle| x_{d+1} = 1 \right\rbrace$.  Let $G \in \mathbb{d \times d}$ be an invertible matrix, let $ v \in \mathbb{R}^d$ such that the pair $(G,v)$ represents the matrix and the center of $MVEE(C)$ respectively. Let $\hat{G} \in \mathbb{R}^{(d + 1) \times (d + 1)}$ be an invertible matrix such that the pair $(\hat{G},\overset{\to}{0})$ represents the matrix and center of $MVEE(C^\prime)$ respectively.  Then, $\forall x \in MVEE(C)$ $$ \left| \left| \left[ x , 1 \right] \hat{G} \begin{bmatrix} x\\1 \end{bmatrix} \right| \right|_2 = (1 + \varepsilon) \cdot \left| \left| (x - v) G (x - v)^T \right| \right|_2 .$$  Regarding $x \not\in MVEE(C) $, then it is easy to see that the above term is not satisfied and moreover the right term is bigger or equal to the left term.  What I need to know is whether it possible the bound the right term by the left term (maybe because $MVEE(C) \times \left\lbrace 1 \right\rbrace \subseteq MVEE(C^\prime)$), i.e. $$ poly(d) \cdot \left| \left| \left[ x , 1 \right] \hat{G} \begin{bmatrix} x\\1 \end{bmatrix} \right| \right|_2 \geq (1 + \varepsilon) \cdot \left| \left| (x - v) G (x - v)^T \right| \right|_2 \ ?$$  Please Do correct if I am wrong and thanks in advance. How can I have an SPF record longer than 255 characters? One of my friends said that I would die if I drank distilled water (we were using it in a chemistry experiment) I gave it a go and surprisingly did not die.  I did a bit of  and found    It said that drinking only this kind of water could definitely cause death, as distilled water was highly hypotonic and it would make the blood cells expand and finally explode and ultimately cause death.  I wanted to know exactly how much of this water on an average was needed to be consumed to cause death. How can I access the "Open command window here" option in Windows without holding shift? I've got a small piece of code that is parsing an index value to determine a cell input into Excel.  It's got me thinking...  What's the difference between   xlsSheet.Write("C" + rowIndex.ToString(), null, title);   and  xlsSheet.Write(string.Format("C{0}", rowIndex), null, title);   Is one "better" than the other? And why? How do I get the path and name of the file that is currently executing? I have scripts calling other script files but I need to get the filepath of the file that is currently running within the process.   For example, let's say I have three files. Using :   script_1.py calls script_2.py.  In turn, script_2.py calls script_3.py.    How can I get the file name and path of script_3.py, from code within script_3.py, without having to pass that information as arguments from script_2.py?  (Executing os.getcwd() returns the original starting script's filepath not the current file's.)
