I can't figure out why my C:\ drive is reporting nearly out of space.  I have a 1TB SSD drive, you can see in Disk Management, that I should be getting about 930GB out of it.   It reports I'm virtually out of space.  I actually keep nearly everything on my D:\ drive (1 TB SSD), there is no valid reason why C:\ should be out of space.  C:\ is virtually nothing more than windows + program installs.   All data goes to D:.  I also did a folder by folder check in C:\, and none of them report any unusual amount of space used, and the 'folder by folder' check adds up to what File Explorer shows for all folders together.  I do NOT use windows recovery, it is turned off.     I do use hibernation, but it's not unusually large.  I do NOT use Veracrypt or any other such software that might make hidden partitions.   I built this O/S myself only a few months ago.   I do not download from the internet on this machine, this is a development laptop.  I run Avast, SpyBot and MalwareBytes + Windows Defender.  The possibility of a virus is near zero.    You can see by my file explorer below, that my clusters size is reasonable, because 'size' and 'size on disk' are nearly identical.  I use R-Wipe &amp; Clean, and I had it delete everything, all browser info, temp files, personal traces, etc.  There is only 1 user on the computer, me.  I ran chkdsk to do a full disk scan and repair, and it reported no errors.   I did run it during boot up so that Windows did not interfere.  I did a defrag, and it said there was nothing defrag.  I delete the recycle bin in case there were ghost trash bins out there.  I physically double checked all temp folders that I am aware of.  I did a manual check for any .dmp or .log files that might be hanging out somewhere.  I've gone through 1/2 dozen different posts on similar issues.   No matter what I try, I can't figure out where the missing 700GB or so went.  I'm literally out of ideas of where this space (roughly 700GB) has gone.  No unexpected partitions.   I should be seeing all files.    I opened C:\, did CTRL-A, and 'properties' to find out what File Explorer calculated.  This amount is what I expect.    When opening 'My Computer'    My hybernation and page files are on C: but are typical sizes.    Volume Shadow Copy output    WinDirStat running in admin, shows 50% utilization.   Still higher than I expect, but closer.    WizTree Output     After looking at results, I followed the 'fat directories' all the way down to Microsoft SQL dump directory.   The directory was protected, and file explorer could not access it.   That's why File Explorer was returning the wrong results.  Here I deleted the dump files, and now it's what I expected:
How can I visualize which folders and files are taking up all of the space on my hard drive?  I'm getting some conflicting reports on the size of hard drive contents. Namely what is and isn't there and what folders are actually using the space.   I need to know which of the files or folders the culprits behind all this hidden bloat. Also there should be a print option to get it on paper.
How do I iterate over the words of a string? I'm trying to iterate over the words of a string.  The string can be assumed to be composed of words separated by whitespace.  Note that I'm not interested in C string functions or that kind of character manipulation/access. Also, please give precedence to elegance over efficiency in your answer.  The best solution I have right now is:  #include &lt;iostream&gt; #include &lt;sstream&gt; #include &lt;string&gt;  using namespace std;  int main() {     string s = "Somewhere down the road";     istringstream iss(s);      do     {         string subs;         iss &gt;&gt; subs;         cout &lt;&lt; "Substring: " &lt;&lt; subs &lt;&lt; endl;     } while (iss); }   Is there a more elegant way to do this? Integral $\int_0^\infty \frac{\arctan(x) dx}{x(1+x^2)}$? How would one evaluate the integral $$\int_0^\infty \frac{\arctan(x) \,dx}{x(1+x^2)}$$?  I was told it had a nice closed form and could have been solved with differentiation under the integral sign; however, I tried to set $$I(\alpha) = \int_0^\infty \frac{\arctan(\alpha x) \,dx}{x(1+x^2)}$$ and got nowhere (the resulting integral was very messy). Is there a much more clever substitution that can be used to tackle the integral? I am new to Force.com and trying to learn some concepts.  Currently I am using Single Email Message to send my emails, but I need to change that to mass email, but I don't quite understand how to do that.   I have also created a Visualforce email template, which I would like to use, but it doesn't seem to work.   It would be great if someone could help me out.  //email_disease_map contains pairs of email address and disease ID for (Id id : email_disease_map.keySet())   {     Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();     String[] defaultAddresses = new String[] {'id@test.com'};      List&lt;String&gt; toAddresses = new List &lt;String&gt; (email_disease_map.get(id));      if (!toAddresses.isEmpty())       {         //set addresses for email to be sent         mail.setToAddresses(defaultAddresses);         mail.setCcAddresses(toAddresses);         mail.setTemplateId(Notification);         //set up remaining email         mail.setReplyTo('test@mail.com');          mail.setSenderDisplayName('Ms Test');          Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });       }  } Grammatical function of "at best" idiom state that "at best" is an idiom. But, what is the grammatical function of "at best" (for example, in the below sentences?)        Their response to the proposal was, at best, cool.   The government's response seems to have been at best confused and at   worst dishonest.   If he drops the course now, at best he’ll get an incomplete, and he could fail.      Thanks Is Object constructor called when creating an array in Java? In Java, an array IS AN Object. My question is... is an Object constructor called when new arrays is being created? We would like to use this fact to instrument Object constructor with some extra bytecode which checks length of array being constructed. Would that work? Creating Workflow -> Error Suddenly mysql/mariadb won't start @Id @GeneratedValue but set own ID value Starcraft Installation asks for a mythical Disk 2 What does first authorship really mean? In my field (theoretical computer science), authors of any paper are always listed alphabetically; our papers .  (Well... hardly ever.)  In most other disciplines, at least within science and engineering, the ordering of authors is a signal about their relative contributions to the paper, with the first author indicating the most significant contributor.  Hiring and promotion committees do give extra weight to "first-author papers" (and sometimes have to be reminded that not all areas have them).  As an outsider, I find this practice confusing.  What does first authorship actually mean in your discipline? I understand vaguely that the first author is supposed to be the one who "", but what counts as "work" in this comparison?  Does "most" mean "more than all the other coauthors together" or just "more than any other coauthor"?  What happens when the comparison is unclear?   How often is "did the most work" the actual truth, versus a cover story for a more complex political decision?  I realize that the precise answer is different for every paper.  I'm looking for general guidelines for how an outsider (like me) should interpret first authorship in your field.  Pointers to guidelines from journals or professional societies would be especially helpful.  Please give only one answer per discipline.

Can we do the same for the remaining two? "The ticket is printing" vs "...is being printed" You're standing in front of a ticket vending machine and it says "The ticket is printing". Is that correct or should it be "The ticket is being printed"?  EDIT:  If both are correct, which one should be preferred or is more common? Lenovo Yoga 13 Realtek wireless driver If $[\cdot]$ denotes greatest integer function, then what is the value of natural number $n$ satisfying the equation $$[\log_21]+[\log_22]+[\log_23]+\dots[\log_2n]=1538 ?$$   My try:  Note that  $$0+1\times2+2\times2^2+3\times2^3+4\times2^4+5\times2^5+6\times2^6+7\times2^7=1538$$  But the answer is $$n=\sum_{i=0}^72^i=255.$$  How is it derived? Why does find -mtime +1 only return files older than 2 days? How can one differentiate between "who" and "whom"? Many times, I've been asked the difference between "who" and "whom". I myself know the difference, but it is hard to explain to others. What is the easiest way to explain it to those with a basic understanding of English? A mnemonic (if possible) would help. When I gain control of a creature, do I also gain control of any auras or equipment attached to it? What would happen if I 'd a creature that had been enchanted by a bestow creature and cast a spell to give it protection from the enchantment's color on it to remove the bestowed creature?  For instance:  They have just bestowed a  on a  and passes the turn. I use Portent of Betrayal to take control of the Asphodel Wanderer, attack and in the second main I cast Gods Willing to give the Asphodel Wanderer protection from black. Nighthowler detaches and where does it go, my control, opponents control or graveyard?  As an additional question, in the same vein:  What if I destroyed the creature while it was on my side? So change the gods willing to a hero's downfall in the example.

Humans' brains are placed in robotic bodies.  The protagonist is a child in one of these bodies.  He has to learn how to control the robot &amp; conserve his battery power.  Once train, he can fight back against the aliens using heat-guns + physical attacks.    The aliens are landing/spawning on sites all over the globe.  Part of the plot is discovering a method to disrupt their staging points.  It was probably young-adult oriented.  If anyone remembers this, thank you.
