I made a Speed Test on my site via online tool. The tool recommended enabling compression to speed up the site. As far as I understand this requires some changes on server (already done by hosting support) and making some entries into .htaccess file. I searched internet and there are many different recommendations about what to enter into .htaccess file.I am just a bit scared to screw things with wrong entries. does anybody know how to implement this method. Thanks
I want to enable gzip compression for acethehimalaya.com. Can anybody please tell me what is the best way of achieving compression in an Apache Webserver?
I am trying to get the SIDs of users and groups by querying  get-wmiobject -query 'select groupcomponent,partcomponent from win32_groupuser`   output:  __GENUS          : 2 __CLASS          : Win32_GroupUser __SUPERCLASS     : __DYNASTY        : __RELPATH        : Win32_GroupUser.GroupComponent="\\\\COMPUTER\\root\\cimv2:Win32_Group.Domain=\"TESTDOMAIN\",Name=\                    "Schema Admins\"",PartComponent="\\\\COMPUTER\\root\\cimv2:Win32_UserAccount.Domain=\"TESTDOMAIN\"                    ,Name=\"Administrator\"" __PROPERTY_COUNT : 2 __DERIVATION     : {} __SERVER         : __NAMESPACE      : __PATH           : GroupComponent   : \\COMPUTER\root\cimv2:Win32_Group.Domain="TESTDOMAIN",Name="Schema Admins" PartComponent    : \\COMPUTER\root\cimv2:Win32_UserAccount.Domain="TESTDOMAIN",Name="Administrator"   groupcomponent is a win32_group ().  win32_group is contains an SID ()  However the groupcomponent here is a string and not a win32_group as   get-wmiobject -query 'select groupcomponent.sid from win32_groupuser'   is an invalid query. How can I access groupcomponent's members as a win32_group? Correcting for multiple kruskal wallis tests I am running a kruskal wallis test a number of times (37) and wanted to know if I have to adjust the p-values of the kruskal tests before I look any further into the post hocs? "It was recommended that" + verb in present tense It was recommended that the international development partners develop guidelines or a roadmap to help countries take the necessary steps to select the right tool for their purposes.   Why is it using present tense "develop" in the sentence which is actually a past tense "It was recommended"? What is the word for when someone is overly nice and actually isn't nice at all because of the unnecessary added information/comments? For example, they will say things like "Your hair looks so good that wayyyy omg you should do it that way ALL the time! Looks way better than how you usually do it." And the word I'm looking for is not passive aggressive and it is not sarcasm. There is a word for these types of people. What is it? These people think they're being kind but actually blunt and rude. Another example would be for someone to say "hey you're beautiful, but maybe if you didn't wear harsh makeup you would look better" and they intend to sound like they're being nice when you know they don't like you and are saying in out of spite. Noise in JPEG file after processing RAW file in photoshop Recently i started shooting in RAW after understanding its advantages over JPEG format.   While processing the RAW file there is an option to reduce noise in a captured picture. It works great when i am working on RAW file. But as soon as I save file in JPEG format, noise comes back.  I understand that while converting from RAW to JPEG compression techniques will be applied. But how can i handle this situation (while doing post processing)? I am a platform diver. I am trying to figure out how deep in the water I go depending on which platform I dive from.  The platforms are 1m, 3m, 5m, 7.5m and 10m above the water surface.  By ignoring air resistance (we assume that I do not do any tricks) I can easily compute the energy that my 90 kg body has when it is hitting the water:  E = mgh = 0.5mv^2   My problem is to find the deceleration in water and thus how deep my feet will go into the water before coming to a halt. We can assume that I stand straight and fall straight down and have a height of 190cm.  How do I compute that? How can I prove that $\mathbb{Q}[x,y]/\langle x^2+y^2-1 \rangle$ is an integral domain?  Also, I need to prove that its field of fractions is isomorphic to the field of rational functions $\mathbb{Q}(t)$?    (The question is taken from ) Show that the polynomial $X^5 + X^3 + \bar{1}$ in $(\mathbb{Z}/2\mathbb{Z}[X])$ is irreducible What is the product of the empty set? Give:  $fn(S)=\prod_{x\in S}x$  what is:  $fn(\emptyset)$  I can see reason that it would be defined as 1 or 0.    Note: I thought about restricting the domain of $S$ but that would make the problem less general. If there is no general answer then answers for restricted domains would be valid. Proof of the square root inequality $2\sqrt{n+1}-2\sqrt{n}<\frac{1}{\sqrt{n}}<2\sqrt{n}-2\sqrt{n-1}$ Can't disable windows 10 PIN complexity I recently linked my Microsoft Office account to my school to have access to Office for students. Right after linking my account, I couldn't login to my computer again with my 4-digit pin code and got the message: "your organization has set the following pin code requirements. Your pincode has to be at least 6 digits long."   I had to change my pincode but I want to change it back to my original 4-digit one. Some internet research has made me enable gpedit.msc, but when I try to find the PIN complexity setting in gpedit (Computer Configuration\Administrative Templates\System\PIN Complexity) it just isnt't there.   Another possible path in gpedit I found on the internet to do this was: Computer Configuration > Administrative Templates > Windows Components > Windows Hello for Business > PIN Complexity, but that also didn't work as I don't have "Windows Hello for Business"   I also tried resetting my computer to the date before I joined my 'organization', but that didn't work either.   Does anyone have an idea how I can resolve this issue? Covering estate tax on US assets for non-resident alien I am a non-resident alien holding a brokerage account in the USA but residing outside the USA. My country does not have an estate tax treaty with the USA. So my estate is liable for a significant estate tax up to 40%. Is there any way to avoid or to cover this tax? I thought of buying term insurance for myself, but I am not sure whether US companies will sell term insurance to a non-resident. I want to buy insurance from a US company because I want the death benefit to be in USD. Can someone suggest as to what the best way to approach this issue is? Google Chrome is not starting I've just installed Ubuntu 16.04 LTS on dual boot. I've looked for many solutions and tried them all but Chrome never starts; the logo appears on the left but no window opens.  I downloaded the deb file on google chrome website and installed it through Ubuntu Software, but it doesn't start.   I have tried installing it through the command line with   sudo dpkg -i --force-depends google-chrome-stable_current_amd64.deb sudo apt-get install -f   I have checked with uname -a and my system is 64 bit. I have also tried gdebi with the same result.   My repository universe is up to date.  I only have one display in settings>displays> so I can't turn off built-in display nor check the mirror display (I read it could be the problem as I also have a graphic card but it seems it is not in my case).  Here is what I get in the command line when I try to run Chrome from it ( the message is the same, whatever the method I used to install Chrome):  ~$ google-chrome [11831:11831:1122/114854.195473:ERROR:process_singleton_posix.cc(433)] readlink failed: Permission denied (13) [11831:11831:1122/114854.195493:ERROR:process_singleton_posix.cc(256)] readlink(/home/basil/.config/google-chrome/SingletonLock) failed: Permission denied (13) [11831:11831:1122/114854.195508:ERROR:process_singleton_posix.cc(256)] readlink(/home/basil/.config/google-chrome/SingletonLock) failed: Permission denied (13) [11831:11831:1122/114854.195515:ERROR:process_singleton_posix.cc(280)] Failed to create /home/basil/.config/google-chrome/SingletonLock: Permission denied (13) [11831:11831:1122/114854.195538:ERROR:process_singleton_posix.cc(433)] readlink failed: Permission denied (13) [11831:11831:1122/114854.195564:ERROR:process_singleton_posix.cc(256)] readlink(/home/basil/.config/google-chrome/SingletonLock) failed: Permission denied (13) [11831:11831:1122/114854.195622:ERROR:chrome_browser_main.cc(1498)] Failed to create a ProcessSingleton for your profile directory.

Let $f$ be a real-valued function continuous on $[a,b]$ and differentiable on $(a,b)$. Suppose that $\lim_{x\rightarrow a}f'(x)$ exists. Then, prove that $f$ is differentiable at $a$ and $f'(a)=\lim_{x\rightarrow a}f'(x)$.    It seems like an easy example, but a little bit tricky. I'm not sure which theorems should be used in here.    ==============================================================  Using @David Mitra's advice and @Pete L. Clark's notes I tried to solve this proof. I want to know my proof is correct or not.  By MVT, for $h&gt;0$ and $c_h \in (a,a+h)$ $$\frac{f(a+h)-f(a)}{h}=f'(c_h)$$ and $\lim_{h \rightarrow 0^+}c_h=a$.    Then $$\lim_{h \rightarrow 0^+}\frac{f(a+h)-f(a)}{h}=\lim_{h \rightarrow 0^+}f'(c_h)=\lim_{h \rightarrow 0^+}f'(a)$$   But that's enough? I think I should show something more, but don't know what it is. PHP validation/regex for URL I've been looking for a simple regex for URLs, does anybody have one handy that works well?  I didn't find one with the zend framework validation classes and have seen several implementations. are the uses of 'bare infinitive' & 'participle' same here? I saw him sing     I saw him singing    In the first example, the verb sing is used as a bare infinitive and in the following one it is exemplified as a present participle. My question is  if both of them are expressing the same meaning? how is this picture made? Good day guys, i have to something like this, any idea how is this picture made ?  so it looks like negative i did invert it in photoshop but the bright side of his face was blue, so there been negative effect and smting been used to change his face to blue before nagative or smting that changed his face to normal skin color after negative ? what can it be ? what do you guys think ? THANKS ! for help.
