Type in &#39;spac&#39; in the search panel of the settings view.

You will find `Editor` -&gt; `Code Style`-&gt;`Java`-&gt;`Tabs and Indents`-&gt;`Use tab character`.

This is a little weird, but others may have the same issue I did.

Yes, follow the above directions, and do the normal changes in the config file.  And guess what? it looks like it&#39;s still making spaces instead of tabs, even though the settings say TABS, not spaces!

Turn on &quot;show whitespaces&quot; (Editor -&gt; General -&gt; Appearance).  And then turn it off.  Looks like this is enough to reset the editor so that it is now following the rules you set in the preferences.

Is there  a way to find out how much time has passed since a web page was changed?

For example, 
I have a page hosted at: `www.mywebsitenotupdated.com`

Is there a way to find out when this HTML page was uploaded to the server?

*I have no access to server; just a link to the webpage.*

How to find when a web page was last updated

It&#39;s a question which has been asked many times, however there is no well supported answer I could find.

Many people suggest the use of top command, but if you run top once (because you have a script for example collecting Cpu usage every 1 second) it will always give the same Cpu usage result ([example 1][1], [example 2][2]).

A more accurate way to calculate CPU usage, is by reading the values from `/proc/stat`, but most of the answers use only the first 4 fields from `/proc/stat` to calculate it (one example [here][2]).

`/proc/stat/` has 10 fields per CPU core as of Linux kernel 2.6.33!

I also found this https://stackoverflow.com/questions/5514119/accurately-calculating-cpu-utilization-in-linux-using-proc-stat question which is pointing out the same issue, -that most other questions only take into consideration 4 out of the many fields- but still the answer given here starts with &quot;I think&quot; (not certain), and except that, it is only concerned about the first 7 fields (out of 10 in `/proc/stat/`)

[This][3] perl script uses all of the fields to calculate the CPU usage, which again I do not think is correct after some further investigation.

After taking a quick look into the kernel code [here][4], it looks like, for example, `guest_nice` and `guest fields` are always increasing together with `nice` and `user` (so they should not be included in the cpu usage calculation, since they are included in `nice` and `user` fields already)

    /*
     * Account guest cpu time to a process.
     * @p: the process that the cpu time gets accounted to
     * @cputime: the cpu time spent in virtual machine since the last update
     * @cputime_scaled: cputime scaled by cpu frequency
     */
    static void account_guest_time(struct task_struct *p, cputime_t cputime,
    			       cputime_t cputime_scaled)
    {
    	u64 *cpustat = kcpustat_this_cpu-&gt;cpustat;
    
    	/* Add guest time to process. */
    	p-&gt;utime += cputime;
    	p-&gt;utimescaled += cputime_scaled;
    	account_group_user_time(p, cputime);
    	p-&gt;gtime += cputime;
    
    	/* Add guest time to cpustat. */
    	if (task_nice(p) &gt; 0) {
    		cpustat[CPUTIME_NICE] += (__force u64) cputime;
    		cpustat[CPUTIME_GUEST_NICE] += (__force u64) cputime;
    	} else {
    		cpustat[CPUTIME_USER] += (__force u64) cputime;
    		cpustat[CPUTIME_GUEST] += (__force u64) cputime;
    	}
    }

So to sum up, what is an accurate way to calculate the CPU usage in Linux and which fields should be considered in the calculations and how (which fields are attributed to the idle time and which fields to non-idle time)?

How can I change spacing in **Android Studio** to use tabs instead of spaces? I tried **Preference -&gt; Editor** but I don&#39;t see the option there. I&#39;m using Android Studio for Mac

Android Studio Tab Spacing

How can I change spacing in Android Studio to use tabs instead of spaces? I tried Preference -> Editor but I don't see the option there. I'm using Android Studio for Mac

I&#39;m using shared preferences to store certain values for my app. I would like to see the file where the info is actually stored on my phone. I found many ways to do this on Eclipse, but I&#39;m debugging on Android Studio. My phone is rooted. I read that having root access is important to read these types of files. If there is no way, then I will look up how to access the info through my program then output it to log cat. Hopefully, though, I can just view the file on the phone directly as it is much simpler. Thanks.

How can I view the shared preferences file using Android Studio?

I&#39;m migrated from Eclipse to android studio **0.5.8**, after importing my project to android studio i was getting the error `Project with path &#39;:progressfragment&#39; could not be found in root project &#39;project_name&#39;.`

Project with path &#39;:mypath&#39; could not be found in root project &#39;myproject&#39;

After importing my project from eclipse into android studio i have got the following error : 

    Error: unmappable character for encoding UTF-8

**Android Studio** : 0.5.8
 

Android Studio : unmappable character for encoding UTF-8

I have no idea what I changed in my project, but it suddenly cannot get past this step while building gradle scripts. 

**There is no problem building it with just &#39;gradle assemble&#39;.** 

EDIT: the previous stuck point was resolve dependencies &#39;detachedConfiguration1&#39;. (After the first failed attempt of _debugCompile, I&#39;m back at detachedConfiguration1).
I guess it is too many dependency projects? Some sample projects I have are imported just fine in the Studio....
I reinstalled the Android Studio and removed all the settings and preferences as well.

I have to kill it every time it starts doing this.


Ring any bells?

Android Studio stuck on &quot;Gradle: resolve dependencies &#39;_debugCompile&#39;&quot; or &#39;detachedConfiguration1&#39;

Is there a shortcut in Android Studio for automatically generating the getters and setters in a given class?
