i am trying to install Ubuntu in an old laptop which is an Dual-core processor and has only 1024 MB ram. I have seen that the system requirement says 2Gb ram but i only have 1Gb. My question is will i be able to install Ubuntu?
For a given hardware configuration, how do I find out if Ubuntu will run on it? What considerations should I take into account when choosing an Ubuntu version and  such as:    with a lighter desktop than the usual Gnome and Unity  with the even lighter LXDE desktop   Obviously Ubuntu does not run on some processor architectures. So how do I go about choosing the right version and derivate. How can I find out the minmal system requirements?
(Almost) double light speed I want to enable GPU rendering, but there is no option in User Preferences > System:    Why is this? How can I get cycles to render using my GPU? Here $n$ belongs to natural numbers. Firstly, I proved the relation by putting $n = 1$ . Then, taking $$|\sin(mx)| \leq m|\sin x|$$ true, I had to prove $$|\sin(m + 1)x| \leq (m + 1)|\sin x|$$  Now, here I got stuck. How to prove it?? Please help. Tracking very long shot with no points in common between first and last frame Is it possible to track an handheld shot (there is already an answer on here about tripod shots: ) that doesn't have any visible points in common between the first and the last frame? As an example, imagine a shot of someone driving in a car for thirty minutes. Obviously everything from the first couple of seconds won't be there anymore at minute 15. Is it possible to smooth or generalize a polygon in QGIS, perhaps by using a plugin like the generalizer-plugin for lines?  I could convert my polygons to lines, smooth them and convert them back to polygons but this is not working for my polygons because of several reasons.

When $b$ is less than $c$ but it would still be a lot of work to multiply $a$ by itself $b$ times, for instance $5^{69}\bmod 101$? When $(a,c)\ne1$, for instance $6^{103}\bmod 14$?  Are there any other tricks for evaluating exponents in modular arithmetic?  This is being asked in an effort to cut down on duplicates, see  and . Omission of verbs This following sentence is puzzling me. Neither can I understand the meaning, nor can I reason the grammatical soundness of the sentence.     Some symbols acquire a multitude of meanings, some widely shared, others personal, some contradictory, conflicted, or ambivalent.   Please help understand the meaning and grammatical explanation. Is it considered plagiarism for a professor to use uncited sources in teaching materials? Kill process after it's been allowed to run for some time I want to limit the time a grep process command is allowed to run or be alive.  For example. I want to perform the following:  grep -qsRw -m1 "parameter" /var   But before running the grep command I want to limit how long the grep process is to live, say no longer than 30 seconds.  How do I do this?  And if it can, how do I return or reset to have no time limit afterwards. Travel alone on accompanied visa How to change from German to English in the File Manager in Ubuntu 15.10? My months and days in my File Manager are in German, how do I change that? On the photo you see 'Dez' : It means Dezember (German for December). I also saw one day Mittwoch (German for Wednesday). How do I change that German issue? This is only my File Manager and not completly but partially. Weird. What is the Stack Exchange (Staff) process of launching a site? What happens if I unsubscribe from Apple Music, then resubscribe at a later date? I want to cancel my apple music subscription for now, but may want to bring it back this summer. Will all the music I added be permanently removed when I unsubscribe, or will re-subscribing retrieve all my previous music? Are common cryptographic hashes bijective when hashing a single block of the same size as the output? How do the sets $\emptyset\times B,\ A\ \times \emptyset, \ \emptyset \times \emptyset $ look like? If we have a function $f:A \rightarrow B$, then one way to give meaning, I think, to this function, in terms of set theory, is to say, that $f$ is actually a binary relation $f=(A,B,G_f)$, where $G_f \subseteq A \times B$ is the graph of the function. Now my question is: what is $f$ if   $\bullet \ A=\emptyset, \ B\neq\emptyset$,?  $ \bullet \ B=\emptyset, \ A\neq\emptyset$ ?  $ \bullet \ B=\emptyset, \ A=\emptyset$ ?  (Another way to formulate this, I think, would be: How do the sets $\emptyset\times B,\ A\ \times \emptyset, \ \emptyset \times \emptyset $ look like? Are they all $\emptyset$ ?) Is a black hole singularity a single point? General relativity is expressed in terms of differential geometry, which allows you to do interesting things with the coordinates: multiple coordinates may refer to a single point, eg. the  has whole lines at the top and the bottom that correspond to the North and South poles, respectively; or a single coordinate may refer to multiple points, for example by using inverse geometry the origin refers to all the points infinitely far away.  So, is the singularity just a single point in the curved spacetime, or can it be a more extended object, described by a single coordinate? Does it matter what I choose for serialVersionUID when extending Serializable classes in Java? If $[G' : G'']\leq p^2$, then $G'$ is abelian. Problem : Let $G$ be a p-group and $G'$ denote the commutator subgroup of $G$. If $[G' : G'']\leq p^2$, then $G'$ is abelian.  It is easy to prove it for the case of $[G' : G'']=1$ since G is solvable. But it is too hard to prove the other cases. Please give me any advice or solutions. Thanks in advance.
