When choosing what RAM to install on a computer and what OS to run how do you determine the amount of RAM that will actually be used and not just recognized?  for example here is my machine:   How did the (3.15 usable) get calculated?
I recently upgraded my computer's RAM to 4&nbsp;GB. My 32-bit Windows installation shows only 3574&nbsp;MB of the memory. How can I make Windows use the full amount of RAM?
WinForms: How to programmatically fire an event handler? Is it grammatically  wrong  to say      It's been too hot  in the last / the past few days      It's been too hot for the last / the past few days     I saw this following sentence also, can we omit in it?     He's had two new cars in the last / in the past three years   as     He's had two new cars  the last / in the past three years     Is there a strict rule in using of preposition or non-preposition when we use the last/past ?  What is the structure when I refer to weeks, months ? Encode URL in JavaScript? How do you safely encode a URL using JavaScript such that it can be put into a GET string?  var myUrl = "http://example.com/index.html?param=1&amp;anotherParam=2"; var myOtherUrl = "http://example.com/index.html?url=" + myUrl;   I assume that you need to encode the myUrl variable on that second line? JSP in /WEB-INF returns "HTTP Status 404 The requested resource is not available" That car is way better than any car any of us have/has ever driven.      None of us know/knows which direction Ron's house is (in).    I have two questions here.   In both the cases, are we to use the singular verb, or the plural? In the end of the second sentence, is using the preposition where it's been used, necessary? Would it be okay if it had no prepositions in it? A cannonball is launched from a point 100 m above ground, at a speed of 20 m/s. This is modelled by the equation $h(t)=-4.9t^2 +20t +100$ The speed of sound (of the cannonball is) 380m/s If a person sitting directly underneath the cannonball runs as soon as they hear the sound do they escape the cannon? My main question is &quot;$y=-380x+100$&quot; the correct equation to model the cannon's sound? How does one prove that addition on $\mathbb{R}$ is associative? How can I modify title page so that it looks like it is in  video. Please seek to 16 seconds and watch title page. I do not have permission to post images. I liked this theme and I want to make a beamer theme that looks similar. I tried with beamercolorbox but I failed to position the box to the bottom.

What is the cheapest way to establish a reliable connection across a 200m stretch (Cat 5e ethernet only works up to about 100m from our tests)? How to change the name of an iOS app? I began an iPhone project the other day with a silly development code name, and now I want to change the name of the project since it's nearly finished.   But I'm not sure how to do this with Xcode, trying the obvious of changing the application's name in the info.plist file, causes the signing process to go wrong (I think...) and my app won't launch giving me a Launcher error.  I guess I could make a new project and copy paste everything over, but it seems so primitive that I'm hoping for a more civilized solution. How can I get a views exposed filter to persist across multiple views? I have 2 separate views that return a set of results for each of my content types. The fields are different, but the filters are exactly the same - Sort by Location / Distance. This Distance / Proximity filter is exposed, and it is set to 'remember' the last entry. I followed the tutorial here  to be able to filter results by distance. It works great.  In views, to remember the last entry, Views uses sessions. But, each view has its own individual $_SESSION variable. That means what I set for one view does not carry over to the next, and even each view can have different values, which is not what I want. Here is a dump of the session after they have been set:  [views] =&gt; Array     (         [search_pages] =&gt; Array             (                 [default] =&gt; Array                     (                     )              )          [baby_clothes_pages] =&gt; Array             (                 [default] =&gt; Array                     (                         [distance] =&gt; Array                             (                                 [postal_code] =&gt; 11211                                 [search_distance] =&gt; 100                                 [search_units] =&gt; mile                             )                      )              )          [baby_gear_pages] =&gt; Array             (                 [default] =&gt; Array                     (                         [distance] =&gt; Array                             (                                 [postal_code] =&gt; 22343                                 [search_distance] =&gt; 100                                 [search_units] =&gt; mile                             )                      )              )      )   What I would like to do is create a small module or snippet of code that will simply allow someone to type in their 5 digit zip code and then it update all the values across all my pages with this filter. If it is changed on any page, then it changes it for the rest of the pages as well. It also needs to work so that it affects the results on the next page load so that it correctly shows them filtered.  Here is a snippet of code I was experimenting with to try to set this value, but it's the wrong direction.   $all_views = views_get_all_views();            // get an array of all views in use on the site  foreach ($all_views['category_pages']-&gt;display as $key =&gt; $value) {  //check to see if the structure exists I am looking to modify if(array_key_exists('postal_code', $all_views['category_pages']-&gt;display[$key]-&gt;display_options['filters']['distance']['value'])) {  //if so, set its value $all_views['category_pages']-&gt;display[$key]-&gt;display_options['filters']['distance']['value']['postal_code'] = '28152';  //try setting the session instead $_SESSION['views']['category_pages'][$key]['distance']['postal_code'] = '28152';     }   What's the correct direction? How do I get this value changed? Could it be done in the template.php file with preprocess function? Should I do it in a module, and if so, what do I need to alter?  Very lost at this point. Thanks for the direction! There is a button in the "basic math assistant" which wraps highlighted text in chosen brackets. Is there no keyboard command for this? Where can I find the source code for the Ubuntu Kernel? I'd like to build my own copy of the Ubuntu kernel. Where can I get the source code? Seemingly random reputation gain of 1 How long should it take to refresh a Developer Sandbox? I refreshed a Developer Sandbox, and almost 24 hours it is still "pending". Is this normal? Are there any actions I can take to speed up the process? When I created the Sandbox it took barely more than 10 minutes to create.  Thanks, Adrian I want to be able to close an alert box automatically using Javascript after a certain amount of time or on a specific event (i.e. onkeypress).  From my research, it doesn't look like that's possible with the built-in alert() function.  Is there a way to override it and have control over the dialog box that it opens?  Also, I don't want an override that shows a hidden div as the alert.  I need an actual dialog box. How do I find out which process is eating up my bandwidth? I think I'm being the victim of a bug here. Sometimes while I'm working (I still don't know why), my network traffic goes up to 200 KB/s and stays that way, even tough I'm not doing anything internet-related.   This sometimes happens to me with the CPU usage. When it does, I just run a top command to find out which process is responsible and then kill it. Problem is: I have no way of knowing which process is responsible for my high network usage. Both the resource monitor and the top command only tell me my total network usage, neither of them tells me process specific network info.  I've found questions here about monitoring total bandwidth usage, but, as I mentioned, that's not what I need. Is there another command I can use to find out which process is getting out of hand?  The command iftop gives results that disagree entirely with the information reported by System Monitor. While the latter claims there's high network traffic, the former claims there's barely 1 KB/s.  I've already tried killing all the obvious ones (Firefox, update-manager, Pidgin, etc) with no luck. So far, restarting the machine is the only way I found of getting rid of the issue. With markdown, you can use some dashes for headings. For example, this: Hello ---- this is some other text  renders as this: Hello this is some other text This is fine and works well. When I want to quote that text is when the problem arises, since this Markdown: &gt; Hello &gt; ---- &gt; this is some other text  When written down shows well in the preview but not when posted:  Hello this is some other text   As an example, see an screenshot of the preview:    and a screenshot of the posted content, where the ---- becomes a &lt;hr&gt;:  Note a similar bug I also reported: .
