How to do relative imports in Python? I converted a raster image to vector in Illustrator CS6 using Image Trace then the Expand option, though when I save as an svg the image looks embossed. I suspect it's due to the layer background being white and the paths not lining up, but I'm unsure how to fix it or prove that theory without manually having to adjust every path.   This is how it looks in Illustrator before I export it:    The image looks like this when saved/exported with art optimized option: Why does a subpanel need separate ground and neutral? Why does a power sub panel have to have separate neutral and ground bars other than code satisfaction?  Does a sub panel need a main breaker if there is one at the main?   Also, does the sub panel need a ground wire connected back to the main panel in the same building? How does finder sort folders when they contain digits and characters? Could we please be a bit nicer to new users? There is a distinct decline in the level of civility on all the sites here.  Some of this is due to new users coming in and posting spam and other nonsense, but the off-topic and downvote buttons are doing a pretty good job of keeping this under control. Unfortunately, a lot of this is coming from more experienced users, and the site's built-in moderation system does not (and probably cannot) handle this very well.  Folks are rushing to pound new users down with &quot;this belongs on meta!&quot;, &quot;this is off topic&quot;, &quot;this is a duplicate!&quot; and &quot;read the Help!&quot;. (Which is correct, but should be done nicer) All this, of course, is accompanied by a flurry of downvotes.  This is not very welcoming to new users who don't know about meta, the Help, or what counts as off-topic. Now I am not proposing that we just allow off-topic, meta, or duplicate questions.  However, I think we could be gentler in the way we express these sorts of things.  Explain what meta and the FAQ are and provide useful links.  Just using please and thank-you when asking folks to read the FAQ or post something on meta would be an improvement.  I also think we could rein in the downvoting a bit.  Not that we shouldn't vote stuff down, but unless a new user's post is clearly spam, voting it down to -1 or -2 should be sufficient to send a message without piling on. I like Stack Exchange and I want it to become a resource for everyone, not just an elitist site for high-rep users on the sites. Is every discrete absolute value non-archimedean? I've been reading Milne's notes on absolute values and local fields (Chapter 7 of the book on algebraic number theory), and a possibly minor point is confusing me.   On page 126, Milne writes, "$K$ is a field complete with respect to a discrete absolute value $|\cdot|$..." and then he talks about things that only make sense for non-archimedean absolute values, like the ring of integers and its maximal ideal.   Is every discrete absolute value on a field $K$ also non-archimedean? This would explain a lot, but I also suspect that it is not true, because I can't find any statement of this fact anywhere.  EDIT: An absolute value is discrete if the value group $|K^\times|$ is a discrete subgroup of the multiplicative group $\mathbb{R}_{&gt;0}$. An absolute value is non-archimedean if it satisfies the stronger triangle inequality $$ |x+y| \le \max (|x|,|y|) $$ or equivalently if the set $\{|1|,|1+1|,|1+1+1|,\ldots\}$ is a bounded subset of $\mathbb{R}$. What are good advanced LaTeX books? A company is any form of business whether it is small or large. Generally the term &quot;company&quot; indicates a particular kind of business dealing in a specific product. An organisation is the larger form and generally comprises of a number of companies.  Simply, a company is an organization, but an organization is not just a company. An industry is the combination of companies in same line of business. Firm, corporation and business  are synonyms of &quot;company&quot;. An Agency is a particular kind of company, which serves as an intermediary between clients (other companies or individuals).  Is this correct? Identify a story about a teen boy who learns to use magic with his lizard companion Proof of Frullani's theorem How can I prove the Theorem of Frullani? I did not even know all the hypothesis that $f$ must satisfy, but I think that this are  Let $\,f:\left[ {0,\infty } \right) \to \mathbb R$ be a a continuously differentiable function such that $$ \mathop {\lim }\limits_{x \to \infty } f\left( x \right) = 0, $$ and let $ a,b \in \left( {0,\infty } \right)$. Prove that $$ \int\limits_0^{\infty}  {\frac{{f\left( {ax} \right) - f\left( {bx} \right)}} {x}}dx  = f\left( 0 \right)\left[ {\ln \frac{b} {a}} \right] $$  If you know a more general version please give it to me )= I can´t prove it. Is there a way to separate variables between multiple notebooks? Split a string by a delimiter in python "Use self" doesn't work? I'm currently working with drivers in Blender 2.81 and want to use self but it doesn't work.   For example drive the rotation by the location, I'm adding a driver to the rotation, check the Use Self box and write self.location.x  Blender return the message: ERROR Invalid Python expression.  Have I missed something, is it a bug?  edit: It is a theorem in elementary number theory that if $p$ is a prime and congruent to 1 mod 4, then it is the sum of two squares. Apparently there is a trick involving arithmetic in the gaussian integers that lets you prove this quickly. Can anyone explain it? How to show $\lim_{n \to \infty} \sqrt[n]{a^n+b^n}=\max \{a,b\}$? Let $a\geq 0$ and $ b\geq 0$. Prove that $\lim_{n \to \infty} \sqrt[n]{a^n+b^n}=\max \{a,b\}$. [Hint: Use the identity $(a^n -b^n)=(a-b)(\sum_{i=0}^{n-1}a^ib^{n-1-i})$]    I need some help! I cannot do it even with the hint... :( Is it safe to check floating point values for equality to 0? I know you can't rely on equality between double or decimal type values normally, but I'm wondering if 0 is a special case.  While I can understand imprecisions between 0.00000000000001 and 0.00000000000002, 0 itself seems pretty hard to mess up since it's just nothing.  If you're imprecise on nothing, it's not nothing anymore.  But I don't know much about this topic so it's not for me to say.  double x = 0.0; return (x == 0.0) ? true : false;   Will that always return true? Resubmitted rejected suggested edits It seems that when a user’s suggested edit gets rejected they can simply re-suggest it, and given the  of affairs of the suggested review queue the suggested edit is quite likely to be approved (or if not this time, then it will almost certainly be approved if they are persistent).    As an example I saw the following  which was rejected, very shortly after I saw almost the  suggested again, this time it got two approvals.  Should there perhaps be some sort of delay until a user can suggest an edit after their suggestion was rejected for the same post? Perhaps a check can be made how large of a difference there is between the two suggestions (though I’m not sure it’s worth doing just for this, and a delay is probably sufficient)?   I do understand that a user should be able to re-suggest an edit after it was rejected, since after all perhaps they made a better suggestion after seeing that it was rejected, however in cases like these I don’t think that is what is happening.  I did see  saying that after some rejected edits a user cannot suggest any further edits until a week has passed, but as this is clearly not happening here I guess that may have changed since that post. $$\sqrt{x + \sqrt{x + \sqrt{x + \cdots}}}= 5$$ A continuous, injective function $f: \mathbb{R} \to \mathbb{R}$ is either strictly increasing or strictly decreasing. how to auto start or enable service on next boot up or start up? in ubuntu 16.04 lts how to start or enable service on the next boot up or start up? in ubuntu 16.04 lts  without doing it manually enable or start services again everytime i start up or boot up the ubuntu 16.04 lts  thank you
