Reorder rows of shapefile in the file
Reordering polygon shapefile permanently?
Creating a query that uses criteria from two tables? How can I import a .c4d static model (Cinema 4d) on Blender? Is there any plugin could help me? I didn't notice anything on Internet. "Shall" versus "will" for the first person When I studied English, I was taught that shall is used to express the future tense for the first person (singular, or plural), and will is used for the same purpose in the other cases.  When I look for shall on the NOAD, I read the following sentence, in a note about the usage of shall:     In practice, however, shall and will are today used more or less interchangeably in statements (although not in questions).   Does that mean shall and will are used with almost the same meaning?  Does I shall return have the same meaning of I will return? Calling Java from MATLAB? Passing parameters from test methods Most of us have heard of Einstein's amazing equations which describe the universe around us, yet only some of us understand what the equations are actually saying.      What are these equations actually saying, and is there a simple (relatively) way to derive them?   Here they are, from :  $$R_{\mu\nu}-\dfrac{1}{2}g_{\mu\nu}R+g_{\mu\nu}\Lambda=\dfrac{8\pi G}{c^4}T_{\mu\nu}$$  I have a vague notion of what a tensor is (it describes things as an array and higher orders define more complex transformations), but I don't understand what all of these tensors are doing. And why is there a $c^{4}$  in the equation!? Catenatives followed by infinitives and gerunds What is the difference in meaning when the catenative verb “like” is followed by an infinitive, or by a gerund? For example:      Do you like ski jumping?    vs.      Do you like to ski jump?   Also, what is the difference between:      My brother taught me to read and write.    vs.       My brother taught me reading and writing. Proof of triangle inequality Ubuntu 18.10 gnome extensions stop working after hibernation After upgrading to 18.10 I am experiencing very strange behaviour of gnome extensions. After my laptop goes into hibernation they all switch off and enabling them back on  doesn't help: nothing changes and when I refresh the page they are disabled again.   The only way to turn them back on is to reinstall them. We have a broadband line coming into our building which delivers around 8-10Mbps, which is okay but not great. Fiber is available in our area (30-100Mbps) but it's not available where we are just yet.   Is there some way we could connect two lines (which we would take from two different providers so we would have redundancy if one failed) and merge them into one signal which we could distribute?  Is there some sort of setup that can do this?  Of course we have the option of a leased line but for 12Mbps symmetrical upload/download we'd be looking at around £500 per month compared to £15 per month for normal or fiber broadband.  I made a small pseudo flow chat of the setup below: Superscript in CSS only? How can I get superscript done, only in CSS?  I have a stylesheet where I mark the external links with a superscript character, but I'm having a hard time getting the character aligned correctly.  What I have currently, looks like this:  a.external:after {   font-size: 50%;   vertical-align: top;   content: "+"; }   but it doesn't work.  Naturally, I'd use the &lt;sup&gt;-tag, only if content would allow for HTML... Proving $T$ and $U$ are equal if I know $(X,T)$ and $(X,U)$ are hausdorff and compact This question is from Wayne Patty Exercise 4.2  Let $T$ and $U$ are Topologies on set X. Suppose $ (X,T) $ and $(X,U)$ are compact Haurdsorff Spaces. Prove that $T=U$ or $T$ is not a subset of $U$ or $U$ is not a subset of T.  I thought of proving it by this way: Assuming that if $T$ is a subset of $U$ or $U$ is a subset of $ T$ then $T=U$ must be true. But I was unable to think on how to use compactness or hausdorff property and was unable to proceed. Well, also this question was asked before on this website. But I am unable to understand how the solution will work despite trying to understand it for a fair amount of time as it was just outlined. So, I am looking for a detailed solution. Why too many capacitors in parallel for Vdd supply net? Can't we just add all to replace with one big capacitor? Analytic continuation of function continuous on boundary Suppose one has a function $f$ in the disc algebra ie: $f$ is continuous on $|z|\leq1$ and holomorphic in $|z|&lt;1$. I wondered, can $f$ always be extended to a holomorphic function on some region containing the boundary (ie: $T$ the unit circle). If not can you give me an example? Thank you, Is there a case where including the same header twice is actually helpful? I want to give a client access to my server, but I want to limit those users to their home directories. I will bind-mount in any files I want them to be able to see.  I've created a user called bob and added him to a new group called sftponly. They have a home directory at /home/bob. I've changed their shell to /bin/false to stop SSH logins. Here is their /etc/passwd line:  bob:x:1001:1002::/home/bob:/bin/false   I've also changed the /etc/ssh/sshd_config to include the following:  Match Group sftponly         ChrootDirectory /home/%u         ForceCommand internal-sftp         AllowTcpForwarding no   When I try to log in as them, here's what I see   $ sftp bob@server bob@server's password:  Write failed: Broken pipe Couldn't read packet: Connection reset by peer   If I comment out the ChrootDirectory line I can SFTP in but then they have free rein over the server. I have found that ChrootDirectory /home works, but it still gives them access to any home directory. I have explicitly tried ChrootDirectory /home/bob but that doesn't work either.  What am I doing wrong? How can I limit bob to /home/bob/?  ----EDIT-----  Okay so I just had a look at /var/log/auth.log and saw this:  May  9 14:45:48 nj sshd[5074]: pam_unix(sshd:session): session opened for user bob by (uid=0) May  9 14:45:48 nj sshd[5091]: fatal: bad ownership or modes for chroot directory component "/home/bob/" May  9 14:45:48 nj sshd[5074]: pam_unix(sshd:session): session closed for user bob   I'm not entirely sure what's going on there,  but it suggests something is wrong with the user directory. Here is the ls -h /home output:  drwxr-xr-x 26 oli      oli      4096 2012-01-19 17:19 oli drwxr-xr-x  3 bob      bob      4096 2012-05-09 14:11 bob Is it possible to query the content of the Time-based Workflow Queue from an Apex unit test to assess that a specific Workflow Rule has been executed and added a new item to the queue? I didn't see anything alike in the documentation, but wish it could be possible to improve testing and stability overtime.  Thanks I'm sure there is a really simple explanation to this but haven't found any pointers on this forum or elsewhere. I seem to have lost the 'processing' menu from QGIS and can't figure out how/why!? Any ideas what I might have done to make this happen?  I'm running QGIS 2.8 built against GDAL 1.10 on Ubuntu 14.04.
