I have a weird problem with Windows 7. It started about 14 months ago. I had 10 GB free space on C on maximum 146 GB. D was okay. Tomorrow, 8 GB free! Next day, 6 GB free until 250 KB free. I cleaned up space somehow and got 3 GB free. Now everyday I have lower and lower free memory. I disabled Windows Update. I think do games write on the disk. I play only LOTR: The Return Of the King. Antivirus is Bitdefender the latest, installed a few days ago. How can I stop filling my hard disk? Programs Files on C is 20 GB but on D 40 GB. I think Windows is filling my HDD with cache and other junk files. How to resolve this?
Possible Duplicates:             does anyone know a free software that will graph the directories on my hard drive and sort them in order of largest size?  or provide me a solution for me to quickly determine what drives/ files are consuming my hard drive space?
How do you find the directory of a command? Claim: Let $X$ be a metric space. If $A,B\in X$ are disjoint, if A is compact, and if B is closed, then $\exists \delta&gt;0: |\alpha-\beta|\geq\delta\;\;\;\forall\alpha\in A,\beta\in B$.  Proof. Assume the contrary. Let $\alpha_n\in A,\beta_n\in B$ be chosen such that $|\alpha_n-\beta_n|\rightarrow0$ as $n\rightarrow \infty$.  Since A is compact, there exists a convergent subsequence of $\alpha_n\;(n\in\mathbb{N})$, $\alpha_{n_m}\;(m\in\mathbb{N})$, which converges to $\alpha\in A$.  We have   $$|\alpha-\beta_{n_m}|\leq|\alpha-\alpha_{n_m}|+|\alpha_{n_m}-\beta_{n_m}|\rightarrow0 \;\;\;as\;\;m\rightarrow\infty.$$ Hence $\alpha$ is a limit point of B and since B is closed $\alpha\in B$, contradiction.  Is my proof correct? I feel as though I am missing something simple which would trivialize the proof. How to use ampscript in order to pull user data from a second data extension? We have several data extensions that have data relationships with each other.  How can I send an email using one data extension while pulling data from a second data extension to personalize my email with ampscript?  I've tried Lookup in many different ways, but I've only managed to pull one specific row (the same row which is not personalized to each user) or all rows at once. I haven't been able to pull personalized data for each user.  In practice, I want to pull data from a DE called "Survey". Each user has a specific ID and some users have an "AnswerID", which varies. I want to to create IF/THEN statements based on that AnswerID.  Thanks, Sylvie I've installed Windows 10 in BIOS mode and use MBR. How can I convert it to use UEFI and GPT without reinstalling Windows 10? Is this possible? Is there a package of Ubuntu drivers as driver pack solution? I tried to search for it, but I did not find it. If there is, how can I easily get it? Let me start by explaining my particle physics background is very patchy, so this question may not be as coherent as  I would like it to be.   In general terms, what is the difference between a resonance found during a particle experiment and a particle?   From reading Wikipedia it seems to be mostly based on timescales. If a heavy particle decays quickly, how can we distinguish it from a resonance?  I would not be posting this question except for the fact that the Wikipedia page says "This page has some issues".        and I would be interested in knowing more about the subject. How to completely disable Siri on Sierra? The new GNU Octave 4.0.1 was released March 23, 2016.  I would like to find some standard way to install it in El Capitan (mine OS X 10.11.3) because it has significantly better support in some functions than Matlab, discussed in the thread .  I do brew search octave and get  homebrew/science/octave    Caskroom/cask/octave       Caskroom/cask/xoctave       where one of the first two should be a correct one. The project's homepage  for OS X is down  about installing Octave on OS X systems.  There is also ruby's way of installing Octave described in the thread  but for Yosemite.  I would like to find some standard way of getting Octave for OS X.   I do successfully brew update and brew upgrade before the commands. My Homebrew is 0.9.5 (git revision 80d1; last commit 2016-03-24).  . I run brew info octave but I get  Error: No available formula with the name "octave"     How can you install Octave in some standard way for El Capitan? Is there any way to attract or repel neutrons? I know that neutrons are neutral and have no charge, but is there any other way to interact with them? Connect Talend to Salesforce using OAuth JWT Flow I followed the steps exactly mentioned here  for connecting Talend to salesforce.  I have done the configuration in Talend and added the test(sandbox) URL in the advanced setting. I am facing an error while trying to establish the Oauth connection (JWT) between Talend ETL tool and salesforce: {'error':'invalid_grant','error_description':'invalid assertion'} Here is the screenshot of the configuration and error message:   Please help to resolve this issue. How do snaps work exactly and why are they mounted? Recently I started learning more about snap packages and what intrigued me was that snap packages are mounted together with their own file system and dependencies (correct me if I'm wrong). Now, with all the great things that snaps bring to the table, what I'd like to know is:  Are snap packages always going to be mounted? This seems kind of awkward, since they appear in places like lsblk and give the impression of not being well integrated into my system.   Also, could they ever replace .deb and .rpm packages completely, or are they a different type of animal and are only complementary to .deb and.rpm packages?  As a side-note, I noticed that some applications are so self-contained that they don't respect any of my desktop settings like the mouse cursor theme or icon and menu themes. When is it acceptable to call GC.Collect? The general advise is that you should not call GC.Collect from your code, but what are the exceptions to this rule?  I can only think of a few very specific cases where it may make sense to force a garbage collection.   One example that springs to mind is a service, that wakes up at intervals, performs some task, and then sleeps for a long time. In this case, it may be a good idea to force a collect to prevent the soon-to-be-idle process from holding on to more memory than needed.   Are there any other cases where it is acceptable to call GC.Collect? How do I make a 3 dimensional character out of flat picture? I have a cartoon character (a lion) that is part of my business logo that I want to put into Blender and animate it somehow. Is there any way I can take a flat picture (JPEG) and transform it into a 3D image and then animate it in Blender? Let $R$ be a UFD. Then for any two elements $a,b \in R \setminus \{0\}$ $ab \sim \gcd (a,b){\operatorname{lcm} (a,b)}$.   My attempt :  Let $d = \gcd (a,b)$.Then $d|a$ and $d|b$.Then $\exists x,y \in R$ such that $a = dx$ and $b = dy$.Now it is to be shown that $c = dxy$ is the lcm of $a,b$.Which I find difficulty to show.It is clear that $a|c$ and $b|c$. Now if $u$ is any common multiple of $a$ and $b$.Then $dx|u$ and also since $y|b$ we have $y|u$ i.e. $dxy|u^2$ $\implies c|u^2$.But I have to show $c|u$ to complete the proof which I fail to prove.Please help me to complete the proof.  Thank you in advance. Exit from both root and user with one command I know about "not using sudo su -" etc. But let's be honest, almost all of us do it.   So, here is the issue. We can't have root logins enabled, so we have to ssh in as our user then su to root.  Here is the process tree:       1  7897  7826  7826 ?           -1 S     1000   0:00 sshd: josh@pts/0  7897  7898  7898  7898 pts/0     8182 Ss    1000   0:00  \_ -bash  7898  7990  7990  7898 pts/0     8182 S        0   0:00      \_ sudo su -  7990  7991  7990  7898 pts/0     8182 S        0   0:00          \_ su -  7991  7992  7992  7898 pts/0     8182 S        0   0:00              \_  -su  7992  8182  8182  7898 pts/0     8182 R+       0   0:00                  \_ ps axjf   I would like to exit from root, then from my user with one command. Is there a way to do this?  BTW exit &amp;&amp; exit does not work because it exits the shell and doesnt process the rest of the command  josh@ubuntu:~$ sudo su - root@ubuntu:~# exit &amp;&amp; exit logout josh@ubuntu:~$ Unsure whether to use "enquire" or "inquire" Do I need a transit visa for a layover in the United Arab Emirates? Do I need a transit visa for a layover via airports in the UAE, such as Dubai International Airport or Abu Dhabi International Airport? If so, what are the requirements for such a visa? Can I get the transit visa on arrival? Were these other people Chronicoms? We know that Enoch is a Chronicom, which is to say a sort of alien temporal observer.   When Enoch and his agents came and kidnapped       Coulson’s team,   for the purpose of sending them where they wanted; were these other agents also Chronicoms? I’m inclined to think they must have been (would Enoch have shared their advanced technology and goals, etc. with mere mortals), but on the other hand only one pod was mentioned. Is Switching the Neutral OK? What’s the worst that can happen if i put a switch in the neutral instead of the phase?   I just found out that 3 light bulbs sockets in my home  are connected this way, it first came to my mind to fix it but then I recalled the flow of current from positive to negative is just a convention since the electrons are charged negatively and they actually flow from N to L so i cant really find an solid excuse to mess with the wiring for the next 2 hrs Is there a word for two persons dodging each other on the street?
