Last night I successfully installed Ubuntu 12.04 64-bit, and then I tried to install Mac OSX Theme following .  But after I installed the last thing, GNOME Tweak Tool, I ran compiz and my Ubuntu bar disappeared, then the system froze, so I restarted, and now all I see is wallpaper; no icons, no bar.   Now I'm using Ubuntu 12.04 Live CD. It's all I can use, live CD.  And one other thing, I have Windows 7 64-bit, and it's full of spyware and trojans. Can I clean it from my Ubuntu?
When I login, nothing happens.   I am presented with my desktop wallpaper.    No Dash, no Launcher, nothing.
Link renders differently on client and server side when preceded by a special character When editing a question on , I observed that a link which was not rendered in the post was hyperlinked in the edit preview (see pictures below). I tried reproducing it in the  to see if this also happens when the post is posted for the first time and observed the same. It seems to be a bug after the shift to CommonMark, leading to the different rendering of links on client and server-side. A link following a special character (without any space) is not hyperlinked in the post but is hyperlinked in the preview. A link separated from the special character with a white space appears to have no such problem. (see pictures below and my ). Link not hyperlinked in post  Same link hyperlinked in preview I was going through the topic "formation of comparative and superlative".       The rule says     When two objects are compared with each other, the latter term of comparison must exclude the former, as in "Iron is more useful than any other metal". If we say "Iron is more useful than any metal", that is the same thing as saying    "Iron is more useful than iron", since iron is itself a metal.   I am finding difficulty to relate the rule with example. In my team, we use Selenium for automation of functional testing. We also do a lot of manual regression testing to make sure the appearance of the rendered web pages is ok. I would like to develop a framework, that would allow comparing screenshots of the "base" live web page, and the web page on the test server after applying the software update. I believe this will drastically reduce the amount of manual regression testing we need to do.   I would like the framework to be able to detect portions of web pages that were rendered differently from each other. An example of such functionality can be  (first image in the article)  I have never worked with image processing and would need ideas on what algorithms are already publicly available that would help me with the task. From what I can see, the simple pixel-by-pixel comparison would not work well, because it does not account for the concept of elements.  Or am I approaching this problem from a completely wrong direction? How to assign same Data to multiple object copies I made many copies of an object, then I thought it would've been better if I made them to share the same Data (being an instance of the same original object), I know how to do it one by one, is there a way to do it for all of them at once? I tried Copy Attribute add-on but didn't find what option can do that, or even if this is possible in the first place. When using the web interface, there is a favorite tags section where you can select a list of tags that you view most frequently.  This has become a cornerstone of my normal  on stack overflow, but it doesn't look like this is possible in the Android app.  There should be a mechanism by which you can add some favorite tags to the nav bar. Clicking these tags will take you to a list of similarly tagged questions.  Perhaps also the feed should include a section for each favorite tag.  These would be presented on their own, much like how "hot new questions" and "new unanswered questions" appear in the feed.  Perhaps something like this: Is  (i.e. repulsive gravity) possible in string theory?  I have read some articles about scientists making assumptions about the existence of anti-gravity, but is it possible in string theory? Evaluation Symbol: Consistent Implementation Is it possible to choose which OS will be loaded using a hardware switch? Punctuation with units I remember reading somewhere that if a unit is abbreviated as one character, there must not be a space between the number and the unit (e.g., 5m, 26K). If the unit is abbreviated as two or more Characters, there must be a space between the number and the unit (e.g., "10 km", "USD 5").   Can you please help me find the source again? Is this recommendation correct? How to change boot priority? Can somebody help me to prove this identity?     $$\prod_{k=1}^{n-1} \left(\;\cos\theta-\cos\frac{k\pi}{n}\;\right) = 2^{1-n}\sin(n\theta)\csc\theta$$   I was thinking of using the properties of the complex numbers and the binomial theorem, because I found this problem in the Complex Variables book from Schaum's, but it did not solve my problem.  Does anyone have an idea?  Thanks in advance! My 3 years old doesn't tell me when he needs to use the bathroom May I get off in an intermediate city of my route during transfer? I want to go from Panamá to Turkey. There're direct flights of Turkish Airlines that are expensive. And there're flights Panamá -&gt; Istambul -&gt; Baku there're cheaper 2 times of the same airline. The transfer in Istambul takes 6 hours.    Will it be a violation if I buy a ticket Panamá -&gt; Istambul -&gt; Baku and leave in Istambul? Node for setting render colour, regardless of lighting I'm trying to make a material node setup to set final render colors, regardless of lighting conditions. Is such a setup possible? Is “I medalled in volleyball” a grammatically correct sentence? According to OED, medal is a verb and a noun. I haven't seen any usage of the word as a verb, but I am assuming the above sentence is correct. The attribute image.itemtype has an invalid value I am using JSON-LD format for Structured data.
