I am using the MS Visual Studio 2012 compiler and I am building in x64 release mode.  Using ifstream I can read files larger than 4GB. The problem is, I can't seek to a position in the middle of a 10GB file.  When I use seekg like this is.seekg (5368709120, is.beg); then is.tellg(); returns -1 which means the seek failed. I am sure that the file exists and the position 5368709120 exists too. It works perfectly fine if I use: is.seekg (100, is.beg); for example.  Using multiple seeks is not an option since the files can get up to 300GB (and using many seeks will be slow).  My question is: how can I get seek to work correctly on a 10GB file without using multiple seeks?
A few weeks back I was using std::ifstream to read in some files and it was failing immediately on open because the file was larger than 4GB. At the time I couldnt find a decent answer as to why it was limited to 32 bit files sizes, so I wrote my own using native OS API.  So, my question then: Is there a way to handle files greater than 4GB in size using std::ifstream/std::ostream (IE: standard c++)  EDIT: Using the STL implementation from the VC 9 compiler (Visual Studio 2008).  EDIT2: Surely there has to be standard way to support file sizes larger than 4GB.
Does anyone have an intuitive explanation of why this is the case? Why is `[` a shell builtin and `[[` a shell keyword?

I have seen the , and it appears that this is handled for you using the -E options:  -E [!]&lt;ext&gt;[=&lt;extparam&gt;] search extensions (! indicates criticality)          [!]domainScope              (domain scope)          [!]mv=&lt;filter&gt;              (matched values filter)          [!]pr=&lt;size&gt;[/prompt|noprompt]   (paged results/prompt)          [!]subentries[=true|false]  (subentries)          [!]sync=ro[/&lt;cookie&gt;]            (LDAP Sync refreshOnly)                  rp[/&lt;cookie&gt;][/&lt;slimit&gt;] (LDAP Sync refreshAndPersist)   So i tried: ldapsearch -h $HOST -p $PORT -x -L -b "$BASE" '*' '+' -E pr=$SIZE  However when the results (even paged results with size = 50 for example) hit 500, I get the same error as if the results were not paged:  Size limit exceeded (4)  I have seen in the man pages there is another option for virtuallistview but have been unable to find examples for it, and as well I dont think my version of ldapsearch has this option.  The goal here is to create a backup using ldapsearch and the -L option to create an ldif file that is suitable for restoring the database.  A few google searches show up with the same problem I'm having, but none have an applicable solution.. "Use self" doesn't work?

Table cells larger than they are meant to be I've created a map system for a game that runs on the principle of drawing the picture of the map from tiles.

The issue is the line between the top 2 tiles and the bottom 2 tiles, I can't figure out why it's gone like this and any help would be appreciated.

I have made .desktop files for Ubuntu 16.04 to access my Google Chrome profiles, but once I upgraded to Ubuntu 17.10 (it worked up to Ubuntu 17.04) they got removed from the dock and I can't pin them back. Sample File: #!/usr/bin/env xdg-open  [Desktop Entry] Version=1.0 Type=Application Terminal=false Icon[en_US]=google-chrome Name[en_US]=Google Chrome Exec=google-chrome --profile-directory=Default Comment[en_US]=Chrome Name=Google Chrome Comment=Chrome Browser Icon=google-chrome Categories=Browser;Internet; Using $g = \frac{Gm}{r^2}$, the force on a point mass located at 1 AU from the Sun ($m = 2 \cdot 10^{30} \text{ kg}$) is about ~0.006 N/kg.  Does that mean that, e.g., a 70 kg person is ~42g lighter during the day, and ~42g heavier at night? That seems like it could make a big difference for things like measuring gold bars or other weight-sensitive items. (Gold arbitrage: buy your gold during the day and sell it during the night! Risk-free profit!)  This makes me suspect that I'm overlooking something obvious, because a ~0.05% weight difference seems like something everyone would have noticed long ago. So what am I missing?    Edit: A few answers below indicate that there shouldn't be any weight difference, because the Earth orbits the Sun in free-fall. But if that's the reason, does that mean that a 1:1 tidally-locked Earth-Sun system wouldn't experience differential gravity from the Sun on opposite sides? That doesn't seem right. Should I add a 'Home' Button to the navigation?

Codomain of function complete implies function space complete Let $(X,d_X)$ and $(Y,d_Y)$ be two metric spaces.   Let $(C_b(X,Y), d_C)$ be a function space with the metric $$d_C(f,g):=\sup\limits_{x\in X} d_Y(f(x), g(x)).$$  Prove that if $(Y,d_Y)$ is complete then $(C_b(X,Y), d_C)$ is complete.  Unfortunately, I have no idea how to approach this problem. I can think of something like this:  Let $(y_k)_k\subset Y$ be a Cauchy sequence converging to $y\in Y$. Then there exists some $f\in C_b(X,Y)$ such that $f(x_k)=y_k$ for all $k\in \mathbb N$. Since $f$ is continuous, $\lim\limits_{k\to\infty} d_Y(f(x_k), y)=0$.  But how do I go from here? As far as I understand, what needs to be proved is that any Cauchy sequence of functions in $C_b(X,Y)$ converges in $C_b(X,Y)$, that is, that the limit is bounded and continuous. But how do we devise such a sequence of functions? How to "grep" for line length in a given range? The &quot;Your Spellbook&quot; sidebar for the wizard includes the following line:  Copying a Spell into the Book. When you find a wizard spell of 1st level or higher, you can add it to your spellbook if it is of a level for which you have spell slots and if you can spare the time to decipher and copy it.  Does this mean that a Wizard 1/Cleric 19 can copy any wizard spell they find into their spellbook? Is there anything preventing them from casting these spells? How does vampirism work? A PC in our group was off on his own following a recurring villain of our groups. He was paralyzed where he could move, and the vampire bit his neck. The vampire said "now you get to remain 19 (years old) forever" before he left the cave. This was all done in RP.  We found him later, and healed up his bite marks. Our characters know of vampires, specifically only the one that bit him (recurring villain), but don't really know how vampirism works, because it isn't a super common thing in this world yet.   My question as the player is:  How does RAW vampirism work in 5e?  Is it a disease that develops over time? Is it something where they have to die and be brought back as a vampire?
