I have Dell Studio 1555.  I want to install Ubuntu. I have downloaded Ubuntu latest version(Ubuntu 14.04.1 LTS) with 32 bit. there was an option with 64 bit (recommended).  First question, Which version should I use?  second question, from where I can get the drivers for the same?  Please help me out,  Thanks, Jay
What is the difference between 32-bit and 64-bit Ubuntu? I've heard the 64-bit platform performs better and can detect more than 4GB of RAM. Also, while some apps haven't ported to 64-bit yet, ia32-libs lets a 64-bit machine run them.  If so, why not promote 64-bit over 32-bit?

The main hero was a TV actor zapped to a alien planet. It had a evil overlord with a virgin priestesses. She wants to get laid but he refuses because the next priestesses is only three. Regardless it's a parody things include a man who was maimed by the evil overlord wants revenge the hero eventually screws the virgin priestesses it cuts to scenes of a train going into a tunnel and a volcano erupting.

Here at Stack Exchange we're working on moving all traffic to SSL. The reason we're not doing logged-in-users only is that one side of the login divide would suffer a redirect from Google every time.  This happens because Google's only going to have http:// or https:// in the results, not both.  Aside from building the SSL infrastructure (), the outstanding question we have is: how do we best transition to SSL?  Here are the relevant bits of our plan (testing on small sites, moving up to stackoverflow.com):   Get SSL ready/enabled (but not linked to) on all domains Start rendering only the &lt;link rel="canonical"&gt; as https:// Start sending a 301 for all http:// requests to https:// (from our domains...of course we can't do anything about all the existing links pointing to us) After a transition period, set all user cookies as secure   So the endgame is having all content delivered over SSL and all HTTP requests redirected.  What we're primarily concerned with is how this will affect PageRank to our sites. We depend a great deal on traffic that comes from Google and want to ensure that doesn't take a dive as we start delivering more security to our users.  The only bits I've found on this that seem to be substantive are  on :     @Frank Yes, I'm certain that Google treats HTTP and HTTPS URLs as separate URLs for crawling, indexing and ranking (I work with the web-search team here at Google). Doing canonicalization with a 301 redirect like you mentioned is a great way to solve this :) –  Oct 23 '10   and the only webmasters video I could find:  The video doesn't have a solid answer, not one I'd base the future of a company on anyway.  Is our transition plan the best way to accomplish an SSL move, at least from an SEO perspective?  If there's other more recent or concrete advice around how a move like this affects Google ranking we'd love to hear about it. Prove that $\binom{m+n}{m}=\sum\limits_{i=0}^m \binom{m}{i}\binom{n}{i}$ I need to proof this following equality :  $$\binom{m+n}{m}=\sum_{i=0}^m \left(\binom{m}{i}\binom{n}{i}\right)$$  This is what I did combinatoric proof:  Left : subset with $m$ members from $m+n$  Right : $\binom{m}{i} \rightarrow$ The number of subsets in set $m$ could also be written as $2^m$ AND $\binom{n}{i} \rightarrow$ the number of subsets with $m$ members from set $n$  In case $ n \leq m \implies \binom{n}{i}=2^n$  So this is what I came up with I still can't see why those expression are equal.  Any ideas? Thanks. When should "no problem" replace "you're welcome" as a response to "thank you"? Suggested improvements to badges index page ()  Currently,  shows the possible badges, number of total recipients, and brief descriptions. However, I have a few suggestions (mostly minor changes) that could make it a bit nicer.   There is no way to see (on that page) which badges I've earned multiple times — they all appear with a green checkmark. It would be nice to show something like "x 4" like in the badges section of the user profile page. For example:      There is no way to see which badges can be awarded multiple times — you have to click on a specific badge to see yea or nay. It would be nice to have a small, simple icon next to badges that can be earned multiple times, similar to the checkmark showing which badges I've earned. The layout would be nicer if the number of recipients for each badge were in a separate column — since the badge images are different sizes, the overlap and ragged right alignment makes the numbers harder to read. An alternative view that groups badges by "achievement level" (gold/silver/bronze) would be nice, as would a view that groups progressive degrees of the same accomplishment.

I have formated USB with FAT32 and GPT. So the only thing left to do would be just to copy all files from ISO to USB. That method worked when it comes to Linux Mint 17.1 and Clonezilla live CD, but when I tried to create bootable USB for Ubuntu 14.04 or Kubuntu 15.04 beta 1 there was an error copying files. Actually, on several occasions (4 or 5) pop-up window appeared.   After ignoring this errors, both Ubuntu and Kubuntu USB boot-up just fine, with no apparent problems in Live mode.   Can someone please elaborate what this symbolic links presents? Will this cause some problem when OS is installed? Consider this picture of sun beams streaming onto the valley through the clouds.

How does the secondary effect of the Heat Metal spell work? The  spell description states:  If a creature is holding or wearing the object and takes the damage from it, the creature must succeed on a Constitution saving throw or drop the object if it can. If it doesn't drop the object, it has disadvantage on attack rolls and ability checks until the start of your next turn...  I am unsure how this disadvantage mechanic functions as a whole. When do you suffer from it and in what ways (if any) can you end it? For example: What happens if you fail the save but cannot drop the object? Does dropping the object later, on your turn, do anything? What happens if you succeed on the save?  Does dropping the object later, on your turn, do anything? I would like it to be assumed that ; however, heat metal can still force you to drop the weapon. I would also like it to be assumed that . Consider a particle in a potential well. Let’s assume it’s a simple harmonic oscillator potential and the particle is in its ground state with energy E0 = (1/2) &#8463;&omega;0. We measure its position (measurement-1) with a high degree of accuracy which localises the particle, corresponding to a superposition of momentum (and therefore energy) states.  Now we measure the particle’s energy (measurement-2) and happen to find that it’s E10 = (21/2) &#8463;&omega;0. Where did the extra energy come from?  In the textbooks it’s claimed that the extra energy comes from the act of observation but I wonder how that could work. Measurement-1 which probed the position of the particle can’t have delivered to it a precise amount of energy, while measurement-2 might just have been passive. No doubt there is entanglement here between the particle state and the measuring device but where, and which measurement?
