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?
How do you compute negative numbers to fractional powers? "Hope you won't" vs "Hope you don't" What is the difference between "Hope you don't mind" and "Hope you won't mind"? What could be a contextual difference between the two? In a situation like the following, which one seems more appropriate?        Expect me to knock on your door sometimes. Hope you don't mind -or- Hope you won't mind (my knocking on your door) Why must I wait two days before accepting my own answer? I got this message today while trying to accept my answer on my own question.  Why must I wait this time, if I am sure that the answer I answered is the right one, just want to understand the point of view?  I faced that just today on Super user and didn't get this message before. CPU governor changes automatically to "performance" under load I have a Lenovo T570 with Xubuntu 18.04 LTS. My current issue is that my cpu speed stepping is kind of going nuts and does what ever it thinks its best.  Sample: when I run my IDE and cpu load increases during build time, the governor changes automatically. I caught the moment during compiling my project with the following call:  martin@martin-ThinkPad-T570:~$ while cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor; do sleep 1; done powersave powersave performance performance   cpufreq-info tells me this:  martin@martin-ThinkPad-T570:~$ cpufreq-info  cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to cpufreq@vger.kernel.org, please. analyzing CPU 0:   driver: intel_pstate   CPUs which run at the same hardware frequency: 0   CPUs which need to have their frequency coordinated by software: 0   maximum transition latency: 4294.55 ms.   hardware limits: 400 MHz - 3.50 GHz   available cpufreq governors: performance, powersave   current policy: frequency should be within 3.50 GHz and 3.50 GHz.

Please take a look at     current policy: frequency should be within 3.50 GHz and 3.50 GHz.

Any idea how I can disable that automatic change?  PS: If you need more details, just tell me where to find them and I will provide them Does a bad grade in one course (with otherwise OK record) affect graduate admissions? I'm currently an M. Phil student in Math and I failed a course last semester because I was not able to hand in a home work assignment (which was worth 40% of my grade) on time (I was 30 minutes late).   Apart from that I'd say I'm a fairly decent student, I got an upper second class honours bachelors degree, I have a B+ and A's for all my other courses in my current programme and I'm almost finished with my first paper to be published.   I've however been deeply worried about this failure as it would reflect poorly on my transcript if I were to apply to a Ph.D or another Master's programme.   Will my failing grade affect my chances of getting into a competitive programme or greatly lower my chances of getting a scholarship? Protect .NET code from reverse engineering? If I use the starting wealth rolls of my class, do I keep any remaining money left over? If I use the starting wealth rolls of my class, do I keep any remaining money left over after I buy equipment?  In D&amp;D 5e you can roll the 4d4 &times; 10 to determine starting gold, forgoing any equipment your class and background  gets.  This is not up for question.  What is up for question is whether or not the PC keeps any remaining gold that they don't spend on equipment.   As far as I have been able to tell, this is not explicitly stated in the PHB nor in the Basic Rules documents. Print lines between (and excluding) two patterns I'm going to submit form using cURL, where some of the contents is come from other file, selected using sed  If param1 is line matching pattern from other file using sed, below command will works fine:  curl -d param1="$(sed -n '/matchpattern/p' file.txt)" -d param2=value2 http://example.com/submit   Now, go to the problem. I want show only text between 2 matching pattern excluding the matching pattern itself.  Lets say file.txt contains:  Bla bla bla firstmatch It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. secondmatch The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.   Currently, lots of "beetween 2 matching pattern" sed command won't remove firstmatch and secondmatch.  I want the result to become:  It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The ^^ notation in various engines Basically, how does the ^^^... notation work in LuaTeX and XeTeX, exactly?  In 8-bit TeX engines (recent TeX, eTeX, pdfTeX, at least), two consecutive identical catcode 7 characters (typically ^), followed by two lowercase hexadecimal digits, are converted before the tokenization step to the corresponding byte.  Namely, ^^6f is exactly equivalent to o: for instance, \sh^^6fw ^^6f will cause TeX to show the letter o.  There is also the notation with two ^ (identical catcode 7 characters), followed by any ascii character (but not two lowercase hexadecimal digits), which is replaced by the character obtained by either subtracting or adding 64 to the character code, remaining among ASCII characters (range 0 to 128).  Unicode-aware engines (I'm thinking of LuaTeX and XeTeX, there are perhaps other less known ones around) also provide ^^^^xxxx and ^^^^^xxxxx for characters whose hexadecimal representation has 4, or 5 digits.  But this does not seem to be done in the same way across engines.  For instance, both LuaTeX and XeTeX appear to accept the notation with 4, 5, or 6 carets followed by the same number of hexadecimal digits, but XeTeX also accepts it for 3, while LuaTeX doesn't. Compiling the following with pdfTeX, LuaTeX, and XeTeX gives different results.  \catcode0=12 \newlinechar=10 \def\loopshow#1{\message{\meaning #1^^J}\loopshow} \loopshow \/   ^^56   ^^^056   ^^^^0056   ^^^^^00056   ^^^^^^000056   ^^^^^^^0000056 {\end\iffalse} \fi} \bye   One weird fact about XeTeX (a bug?) is that  \show ^^^^^^010101   shows the character displaywidth.  My goal (there may be a better way to do this) is to provide a way to test whether passing a given list of tokens through \scantokens is safe.  For that, my plan is to go through the \detokenized token list one character at a time, applying TeX's rule for tokenizing (but no need to fully tokenize), and detecting begin-group and end-group tokens, as well as invalid characters. Explanation of method for showing that $\frac{0}{0}$ is undefined An integrable and periodic function $f(x)$ satisfies $\int_{0}^{T}f(x)dx=\int_{a}^{a+T}f(x)dx$. I want to prove:     For an integrable function $f(x)$ and periodic with period $T$, for every $a \in \mathbb{R}$, $$\int_{0}^{T}f(x)\;dx=\int_{a}^{a+T}f(x)\;dx.$$   I tried to change the values and define $y=a+x$ so that $dy=dx$ and the limits of the integrals are as we want, but I'm not sure how to use the fact that $f(x)$ is periodic.  Thanks a lot! The model used to open the store is incompatible with the one used to create the store What does the term "86'd" relate to?

It is created using material nodes and works fine in Cycles. However, EEVEE doesn't displace my meshes truly, only normals are changed. Is it possible and how to solve the problem now or in the future? Show $100+t$ is reducible in $\mathbb{Z}[[t]]$ $\mathbb{Z}[[t]]$ is the ring of formal power series with integer coefficients, and the problem asks to show that $100+t$ is reducible. This means I need to find two power series, $\sum_{i=0}^\infty a_i t^i$ and $\sum_{j=0}^\infty b_j t^j$ with $a_i,b_j\in\mathbb{Z}$, that when multiplied give $100+t$. Since the integers are an integral domain, I know that neither of these power series may be finite, but I'm having a really hard time figuring out how to come up with two series that will telescope properly. Any suggestions? translation invariant of integral on $\mathbb{R}$ Problem 1: Let $f\in L^1(\mathbb{R})$, show $\int_\mathbb{R}f(t)dt=\int_{\mathbb{R}}f(x+t)dt,\forall x\in (-\infty, \infty)$.  Problem 2: Let $f\in L^1(\mathbb{R})$,show $\displaystyle \lim_{t\rightarrow 0}\int_{\mathbb{R}}|f(x+t)-f(x)|dx=0$.  My try for Problem 1:  Consider $\displaystyle \int_{\mathbb{R}}f(t)dt=\lim_{n\rightarrow \infty}\int_{-n}^nf(t)dt=\lim_{n\rightarrow \infty}\int_{\mathbb{R}}f_n(t)dt$, where $f_n(t)=f(t)\chi_{[-n,n]}$.  And since $dt=d(x+t)$, we have $\displaystyle \int_{-n}^nf(x+t)dt=\int_{-n+x}^{n+x}f(t)dt$.  So for each $x\in (-\infty,\infty)$,  $$ \begin{split} \int_{\mathbb{R}}f(t)-f(t+x)dt &amp;=\lim_{n\rightarrow \infty}\int_{\mathbb{R}}f(t)(\chi_{[-n,n]}-\chi_{[-n+x,n+x]})dt\\ &amp;=\lim_{n\rightarrow \infty}\int_{\mathbb{R}}f(t)(\chi_{[-n,-n+x]}-\chi_{[n,n+x]})dt\\ &amp;=\lim_{n\rightarrow \infty}\lim_{k\rightarrow \infty}\int_\mathbb{R}\varphi_k(t)(\chi_{[-n,-n+x]}-\chi_{[n,n+x]})dt\\ &amp;=\lim_{k\rightarrow \infty}\lim_{n\rightarrow \infty}\int_\mathbb{R}\varphi_k(t)(\chi_{[-n,-n+x]}-\chi_{[n,n+x]})dt \end{split} $$ where $\varphi_k(t)$ is simple function pointwise converges to $f(t)$, simple function vanish out of set of finite measure, so $\varphi_k(t)(\chi_{[-n,-n+x]}-\chi_{[n,n+x]})$ vanishes when $n$ big enough(is this right?)    Another try:  Since $f\in L^1$, $f$ is bounder a.e. so can be approximated by simple functions, and $\chi_{A+t}(x)=\chi_A(x-t)$,thus $$\int f(t)=\lim_n\int\varphi_n=\lim_n \sum_{i=1}^nc_i\mu(E_i)=\lim_n \sum_{i=1}^nc_i\mu(E_i-x)=\int f(t+x)$$  For problem 2, I guess they share the same method.   Any help or correction about these two problems? Thanks.

I like to be able to configure things from the command line, so that when I reinstall the OS I can just run a script and get my preferred configuration back.  Since "upgrading" to Ubuntu 17.10, I found I had to use gnome-tweak-tool to get some settings the way I want them.  Once I find a setting in the gnome-tweak-tool GUI, how can I figure out its scriptable translation?  For example the following gsettings lines match the relevant entries in the gnome-tweak-tool screen shot below...  gsettings set org.gnome.desktop.wm.preferences titlebar-font "Tahoma Bold 8" gsettings set org.gnome.desktop.interface font-name "Tahoma 8" gsettings set org.gnome.desktop.interface document-font-name "Tahoma 8" gsettings set org.gnome.desktop.interface monospace-font-name "FixedSC 10"    ...but how could anyone guess that? And how would I, for example, figure out where to get the corresponding settings for hinting and antialiasing?
