Recently, I overreacted over a question ban thanks to this question     (Question Deleted), but I  was searching for a little while, and I found this.    While it was closed once, it was reopened, and has not gotten any bad criticism. I was trying to communicate almost the exact same thing in my question, but it was closed, deleted, and down-voted. Why was this question not attacked like mine??
I am posting this question just to get a better understanding of the questions that can be asked on Stack Overflow.  I find that  can several answers based on users opinion and cause a discussion.  Why is this a good question when several other requests for books and tutorials are not acceptable?
I'm trying to install  on my Ubuntu box (11.04). The website has a Ubuntu .deb available for download (for 10.10 and 10.04 so I chose 10.10).   However,   sudo dpkg -i mysql-workbench-gpl-5.2.34-1ubu1010-amd64.deb   yields:  (Reading database ... 194069 files and directories currently installed.)

(Or alternatively, is there some other way to get MySQL Workbench easily up &amp; running?) What are the different colors on the unity launcher icons? Example:      My question is simple.  What are the different colors representing in the unity launcher background for each icon.  I mean, it seems consistent (firefox is always orange), but it's not jumping out at me what the pattern is.  On my screen, it's:   Firefox: Orange Chrome: Yellow Terminal: Grey RDP App: Blue KeyPassX: Green NetBeans: Blue   I'd like to turn it off if possible, but first I'd like to understand more about it.  Any launcher experts? Is there a test for the different styles within maths mode?  What I really want is to be able to save the current style to reinvoke it later on, but a \if along the lines of \ifmmode would work just as well.  In the specific example, I want to measure how big something will be when displayed in maths mode, so I do:  \settoheight{\mathheight}{some bit of maths}   except that it complains because the some bit of maths gets put in a box and measured, and the box doesn't know that it's maths.  So instead I put:  \settoheight{\mathheight}{\(some bit of maths\)}   except that then I get the wrong answer if this is used in displayed maths.  So ideally, I want:  \ifdisplaystyle  \let\currentstyle\displaystyle \else  \iftextstyle   \let\currentstyle\textstyle  ...  \fi \fi \settoheight{\mathheight}{\(\currentstyle some bit of maths\)}   and then I'll be happy.  Is there such a test?    Okay, so \mathchoice is clearly the way to go (thanks Martin!), but its behaviour is a little odd and since I want to use it to define a macro depending on which mode I'm in, this oddity is quite important.  Here's the code:  \newcommand{\mathtest}{% \gdef\name{a}% \mathchoice{% \name \gdef\name{b}% }{% \name \gdef\name{c}% }{% \name \gdef\name{d}% }{% \name \gdef\name{e}% }% \name}  \[ \mathtest \]   If \mathchoice behaved like \if, this ought to print ab.  But it prints ae.  All the options to \mathchoice get processed (which makes me wonder a bit how it works, but that's by-the-by).  So, is there an obvious way to make \mathchoice behave a little more like \if? I have an unlocked North American (Canada) iPhone 5s, where can I buy a data only SIM card in Japan ? I'm not interested in renting nor in a voice plan, I'll be staying for 4 weeks.  I'll be landing in Tokyo, so preferably around there. Can I get them from the airport somewhere ? I'm assuming I won't have problems with the network/frequencies, am I correct ? Subdomain versus subdirectory I recently moved from having a main site like www.example.com with a subdomain associated site yyy.example.com, to moving everything off the subdomain to a subdirectory like www.example.com/yyy/, with the same hierarchy underneath the subdirectory, and now yyy.example.com is just a redirect page to the subdirectory, so yyy.example.com/abc/page-x is redirected to www.example.com/yyy/abc/page-x and so on.  The effect has been that the traffic increased by several times (the total page views are more than ten times at the present rate) what it was to the yyy subdomain. Previously almost all of the traffic to the yyy subdomain was from the www site. This is from monitoring the old yyy site for a year or more.  I'm curious to know if there's any research or results which would indicate whether this is universal (subdirectories beat subdomains) or "just me". is it possible to redefine { and } in C? Mountain Bike on Paved Roads I'm an occasional biker. I bought a mountain bike (nothing fancy) with the idea that I might use it off-road or on mountain trails (of which there are many here in Calgary). However, since I've bought it I've done nothing but bike in the city on streets and paved bike trails.  Is there anything worth doing to my bike to convert it to something more suited to urban biking? In particular, the tires have me wondering; they have large rubber off-roading lugs that surely aren't doing me any favors on pavement. I'm not looking to spend a tons of money on a retrofit, but will do so if its worthwhile. Difference between get "off of" and "off" Regression: Transforming Variables Make OS X Terminal commands I type BOLD I'd like to make commands I've typed (input) into terminal stand out from all the output.

If you look at this product:    you can clearly see that it is a DVD+R, i.e. once it is written, it cannot be erased/rewritten.  Then what does the "RW" logo (in the lower right corner) mean? I thought it stood for ReWritable, but experimenting with the medium shows that it is not. I am planning to visit the UK on a USA travel document but there’s nowhere I am able to find information about visas: I’m a Zimbabwean but using a USA refugee travel document do I need to apply for a UK visa before I travel or I can they just give them on arrival. Is "Five dollars is all I have" correct? Suggested improvements to badges index page ()  Currently,  shows the possible badges, number of total recipients, and brief descriptions. However, I have a few suggestions (mostly minor changes) that could make it a bit nicer.   There is no way to see (on that page) which badges I've earned multiple times — they all appear with a green checkmark. It would be nice to show something like "x 4" like in the badges section of the user profile page. For example:      There is no way to see which badges can be awarded multiple times — you have to click on a specific badge to see yea or nay. It would be nice to have a small, simple icon next to badges that can be earned multiple times, similar to the checkmark showing which badges I've earned. The layout would be nicer if the number of recipients for each badge were in a separate column — since the badge images are different sizes, the overlap and ragged right alignment makes the numbers harder to read. An alternative view that groups badges by "achievement level" (gold/silver/bronze) would be nice, as would a view that groups progressive degrees of the same accomplishment.

I would like to know how to transform negative values to Log(), since I have heteroskedastic data. I read that it works with the formula Log(x+1) but this doesn't work with my database and I continue getting NaNs as result. E.g. I get this Warning message (I didn't put my complete database because I think with one of my negative values is enough to show an example):   &gt; log(-1.27+1) [1] NaN Warning message: In log(-1.27 + 1) : NaNs produced &gt;    Thanks in advance  UPDATE:  Here is an histogram of my data. I'm working with palaeontological time series of chemical measurements, E.g the difference between variables like Ca and Zn is too big, then I need some type of data standardization, that is why I'm testing the log() function.   This is my Conjugate class in the dihedral group A message may be accompanied with a digital signature, a MAC or a message hash, as a proof of some kind.  Which assurances does each primitive provide to the recipient?  What kind of keys are needed? I am relatively new to game development, and am working on a simple 2D platformer. I have created a tilemap and painted some tiles for the character to walk on.. but he is getting stuck. Yes, I know this is a common question and I did find some answers (including this one: ), but none seem relevant for me. The thing is my tiles are not flat.. they have pointy edges due to grass.. see the image below:  As you can see, the edge is not flat. I have overcome the problem of getting stuck by changing the &quot;Edge Radius&quot; to what you see in the above screenshot and that works, but the character now looks like he is floating slightly above the ground. Is there any way I can just tell Unity to ignore the jagged grass and make the collider flat and move the edge of it down a bit? That way it would fix the issue and also have the added bonus of looking like some of the grass is behind him and some in front.. How do I select all the columns in a table that only contain NULL values for all the rows?  I'm using MS SQL Server 2005.  I'm trying to find out which columns are not used in the table so I can delete them. Combining all the address fields into one?
