Latitude & longitude universal format
GIS Point or discrete longitude and latitude columns?
When looking at my objects in 3d view I'm seeing a gray cone that seems to be hiding other objects.   Can anyone help me turn this off and explain what it is please.  Screenshots attached. Alright, I'm toying around with converting a PIL image object back and forth to a numpy array so I can do some faster pixel by pixel transformations than PIL's PixelAccess object would allow.  I've figured out how to place the pixel information in a useful 3D numpy array by way of:  pic = Image.open("foo.jpg") pix = numpy.array(pic.getdata()).reshape(pic.size[0], pic.size[1], 3)   But I can't seem to figure out how to load it back into the PIL object after I've done all my awesome transforms.  I'm aware of the putdata() method, but can't quite seem to get it to behave. Is it possible to disable X at boot time? I'm setting up a server so it would be nice if it wouldn't load the graphical interface every time I boot. New to Macbook Pro, need help upgrading I was recently gifted an old Mid 2010 Macbook Pro with the following specs listed here:    I would like to do a few things to it, but I have never owned an apple computer before and I know there are some restrictions on the hardware i can purchase to upgrade it.  These are the things I want to do  1) Upgrade Ram: Currently it has 2x2GB of RAM in it. This model is rated for up to 8GB but I have been reading online and it seems some people have been able to successfully install 16GB of RAM, so i am confused. Does anyone have a definitive statement on whether or not this Macbook Pro will work with 16GB of RAM? If it does accept 16GB total which RAM should i buy for a Macbook Pro like this? If it only accepts 8GB total which RAM should i buy? And I know the clock speed must be 1066Hz for this Macbook Pro, but can i use DDR3, or DDR4 RAM? Does the DDR type matter?  2) Install Secondary Hard Drive: I am not 100% so i need someone to inform me but i believe there is space in this Macbook Pro for a second hard drive. Does the CD Drive need to be removed in order for a second Hard Drive to be put in? Or is there simply space inside it for a second hard drive but not installed by Apple? Either way I would like to install an SSD into it and install the Operating System onto that SSD. Which SSD can i look to buy that is compatible with this  Pro?  3) Fresh install of Mac OSX: As it currently stands my friend who gave this laptop to me didn't erase his data. I am uncomfortable with this and want a fresh start. How do I do a fresh install of Mac OSX Mavericks (or should i wait for Yosemite?). Where can i buy a Disk/USB for it (or make a disk/USB for it) to do a clean install and how do i format a Macbook Pros hard drive and install fresh? Should this be done at an apple store?  4) Higher Screen Resolution: This is my lowest priority and I don't think it is possible to do without major invasive changes to the Macbook Pro but i want to know if it is possible. Currently the Max Resolution on the Device is 1440x900, i would like to know if it is possible to replace the LCD with one that is 1920x1080 for high resolution. How to Merge columns in crystal report I'm using X11 forwarding over ssh to run Linux apps on my Windows box, and when the network drops it loses everything that was running. Is there anything similar to screen for X11? How to make read-only file system writable? At some point, the filesystem on my digital audio player has become read-only. I cannot copy files into it or remove files on it.  Are there some possible reasons for the player's file system to change permissions in this way?  I tried using chmod:  $ sudo chmod a+rw SGTL\ MSCN/  chmod: changing permissions of `SGTL MSCN/': Read-only file system   SGTL MSCN is the mount point of the digital audio player.  What else can I try to make it writeable? Sending Email in Android using JavaMail API without using the default/built-in app Normal text is invisible when using beamer with notes and XeLaTeX One thing I've noticed about the relatively new sitewide layout is that I can't find a quick way to get back to www.stackexchange.com without finding StackExchange in the sites list. As a result, I am typing stackexchange in my toolbar a whole lot more often now. In particular, I tend to enjoy browsing the hot questions list and my own personal feed quite often so visit these pages on a daily basis. Is there an easy link to them that I'm missing?  (On the android app, there is a feed in the menu that I really appreciate, something like that on the desktop would be ideal!) How do I connect multiple devices to an ISP that gives web-based portal for logging in? Can you not sell/destroy buildings? So I've started playing Gathering Storm, built a bunch of coal plants and now Global Warming is out of control mainly because of me. I've been trying to remove these power plants, but I haven't found any option to sell/destroy or even replace these buildings.  Is there seriously no way to do this? I met an interesting issue about C#. I have code like below.  List&lt;Func&lt;int&gt;&gt; actions = new List&lt;Func&lt;int&gt;&gt;();  int variable = 0; while (variable &lt; 5) {     actions.Add(() =&gt; variable * 2);     ++ variable; }  foreach (var act in actions) {     Console.WriteLine(act.Invoke()); }   I expect it to output 0, 2, 4, 6, 8. However, it actually outputs five 10s.  It seems that it is due to all actions referring to one captured variable. As a result, when they get invoked, they all have same output.  Is there a way to work round this limit to have each action instance have its own captured variable? Why does pluralization of compound words typically occur in the middle as opposed to the end of the word? As I understand, correct plural versions of passerby and attorney general become passersby and attorneys general.  But why?  With passerby, the the preposition "by" has been combined with the noun "passer" to become a one word noun "passerby".  So why shouldn't this be passerbys?  If I am an attorney general, and you are an attorney general, why are we not attorney generals?  As an American I have always heard it as attorneys general, however  suggests British English does use "attorney-generals" (as well as an interesting 2nd paragraph that further probes my question).  Are there hard rules to this topic?  Or merely generally accepted practices based on locale? EDIT:  My question was poorly worded.   I wasn't asking about showing $\ln(1+x) &gt; \frac{2x}{2+x}$ for $x&gt;0$.   What I wanted to know is why the lower bound provided by $ \frac{2x}{2+x}$ was so tight for small positive values of $x$. This is addressed in robjohn's answer. Is it possible, on Debian with Klipper running, to have a separate "clipboard stack" for a particular application?  I'd like the text that I copy in application Y not to be shared with all the other applications running.  All the solutions mentioned at  seems like overkill.

If yes, do they have different meanings? It seems to me that I came across both of them in books, but I'm not sure. How do I check to see if a column exists in a SqlDataReader object?  In my data access layer, I have create a method that builds the same object for multiple stored procedures calls.  One of the stored procedures has an additional column that is not used by the other stored procedures.  I want to modified the method to accommodate for every scenario.
