I'm working on a Inventory System where users make orders using a form. The user will fill a couple of fields and then he will choose the products that he wants.  I'm wondering on how to show the items added by user. The simplest way is to use a table, and every time the user choose a product, add a row in this table, with the info about that product. Something like this:    Another possible way (and I don't know if it is good) is to show the items listed as cards, like this:    An important point here is that there are fields that have to be shown, and some of them have to be editable.  The question is: which one is the best way to show the items?
I am in the process of redesigning an interface with a lot of Tabular data that is previously simply used as tables that look like the 19th century. I was a bit confused whether to switch it to a Card View sort of layout and present the data in that way, or to leave it in a Tabular View itself and instead just style around it.  I would like to know what could be the better approach when it comes to User Experience and what seems more at ease to the customer as I want the product to be easier for the customer to use rather than looking complicated to them.  The users of the product would be on the financial sides of the industry so, if needed please keep that into consideration.
Proving $\mathbb{Q}$ isn't homeomorphic to $\mathbb{Z}$ Prove that $\mathbb{Q}$ isn't homeomorphic to $\mathbb{Z}$  I know that a homeomorphism is a bijection function from two sets where both the function and its inverse are continuos.   So I figure that if I show that there is no continuos invective mapping from $\mathbb{Q}\rightarrow\mathbb{Z}$ then I have done the proof. But I do not know how to do this (if his is the right way). How can I start to show this? "He saw it stop and his son get out" I have been reading Men With Brooms for a few days. I read a sentence which did not make any sense to me, so I landed here to get some help on it. I have pasted the sentence from the novel. Please go through it and let me know your valuable feedback on it.  An excerpt from the novel (Men With Brooms: A Sweeping Epic, paperback 2002, a novelization by Diane Baker Mason):     Gordon was about to walk away from the Impala when he saw it stop and his son get out. So it was real the boy had come.   As per my opinion it should have been:     Gordon was about to walk away from the Impala when he saw it stopped and his son got out. So it was real the boy had come.   I have two questions here:   Why did the writer use stop and get instead of stopped and got? As she is telling us a story which happened in the past. Let's say the writer is telling us her mind's situation and she used the present tense for it but why did she use stop and get instead of stops and gets? Restart my graphics card without rebooting? Noise in JPEG file after processing RAW file in photoshop Recently i started shooting in RAW after understanding its advantages over JPEG format.   While processing the RAW file there is an option to reduce noise in a captured picture. It works great when i am working on RAW file. But as soon as I save file in JPEG format, noise comes back.  I understand that while converting from RAW to JPEG compression techniques will be applied. But how can i handle this situation (while doing post processing)? How to make Stack Overflow tell you about a new question with certain tag(s) the second it is asked? I've been trying to wrap my head around the basic concepts of category theory, and I thought I would attempt to illustrate what I understand with the category of sets, probably the easiest example. Particularly, I've been trying to prove that $id_A$ (the identity morphism on $A$, for all $A \in Obj(\mathbf{Set})$) is $1_A \colon A \rightarrow A, x \mapsto x$.  This is a very intuitive and reasonable statement, and it's trivial to prove that $1_A$ is indeed an identity morphism on $A$, and I suppose uniqueness of $id_A$ can be demonstrated analogously to uniqueness of the identity element in a monoid (considering the subcategory which has $A$ as its only object, and endofunctions on $A$ as its only morphisms).  In this manner, it is not hard to prove that the proposition in the title is true, but this demonstration requires to make an assumption or guess as to what could $id_A$ be. Specifically, the scheme of the proof is: assume $id_A$ = $1_A$, see that it works with the definition of an identity morphism, show that the identity morphism is unique, and, in conclusion, $id_A$ can only be $1_A$. What I'm looking for, nonetheless, is a somehow more direct proof, that doesn't assume $id_A$ = $1_A$ at the start. I want to place myself in a state of little or no knowledge about sets and functions, and under this assumption, why would I assume $id_A$ = $1_A$ at first? Why not try with $id_\mathbb{Z}$ = $f \colon \mathbb{Z} \to \mathbb{Z}, x \mapsto x^2 + 1$, for example? It wouldn't work, but I don't have any reason to think that $1_\mathbb{Z}$ is a better guess for $id_\mathbb{Z}$.  I suppose that the proof for which I'm asking would work for categories of sets with additional structure, and probably for posets as well, although I'm not clear as to what modifications it would require to work.  Thanks. (Ubuntu/Linux)"find" command gives different results based on quotation marks I was using   find -iname *prib*   and getting only one result "./prib09jack.pdf" with   find -iname "*prib*"    I get many more results that I was looking for such as  ./Dir1/PRIB09/prib09jackTFF1.pdf   and many more, but why did it matter that the quotation marks were around "prib"?   Best. When does $\,n\mid q^3 \Rightarrow n\mid q\,$? I think this is true because of prime factorisations, i.e.  If $3$ a factor of the prime factorisation of $q^3$, then $3$ is a factor of the prime factorisation of $q$.  Therefore If $3$ divides $q^3$, then $3$ divides $q$.  Or for a general case, if $n$ divides $q^3$; then $n$ divides $q$. Is this correct?

Getting absolute path of a file Copying prod multi-site installation to dev multi-site installation I am attempting to upgrade my Drupal 8.9.2 multi-site installation to D9. I was hoping to work this all out on a development installation, that is located in a subdirectory of my home directory on my NameCheap Shared Hosting plan. When I first installed this installation, I did so using the tarball method from years ago. I then followed the instructions given here (). I was able to get the current running prod version converted to use composer with out an issue. Before I go and start messing with the files, and attempting to upgrade to D9 through composer on a prod installation, I wanted to copy these files over to another installation where I can use it as a sandbox. To do this I:  copied the files on my server to a new directory made clone databases for the new installation truncated all the cache tables in the cloned DB changed all the database settings in the settings files to point to the cloned databases  I've done this before without any issues, and now I seem to be getting a WSOD error on all the sites running from the new installation. The error I'm getting is  PHP Fatal error:  Uncaught Error: Class 'Drupal\Core\Cache\DatabaseBackend' not found in ~/{new installation dir}/public_html/index.php:16.  If anyone has any thoughts what's going on I am all ears. Thank you in advance Onomatopoeia for disgust Texture Channel animated, doesn't appear in viewport I'm creating an educational video, and for efficiency, I'm using a Cyclic repeater to repeat an on-page/off-page effect.  Every loop, I have the texture channel switch to the next image, rather than duplicating all the objects/animations. This works properly and appears when rendering the animation, but does not appear in the viewport. It sticks to the original UV image that was mapped.  Is there a way to have this change appear in the viewport? Suppress a biblatex field in only one of split bibliographies? I am aware of \clearfield, \clearlist etc (cf. ) - but I'm really not sure how to apply it in this context:  Say you have a split bibliography (i.e. several calls to \printbibliography in one document). How can you filter a specific field in a bibliography item - but only in one bibliography (i.e. only in one call to \printbibliography)?  For instance, in the MWE below (compiles with pdflatex test.tex &amp;&amp; biber test &amp;&amp; pdflatex test.tex &amp;&amp; pdflatex test.tex), let's say I'd like to filter urldate (i.e. urldate is not typeset) only in the first bibliography - but for the second one, the original/default behavior should be restored (i.e. urldate is typeset). How to I do that?  \documentclass{article} \usepackage{filecontents} \begin{filecontents*}{\jobname.bib} @online{ctan,   title        = {CTAN},   date         = 2006,   url          = {http://www.ctan.org},   subtitle     = {The Comprehensive TeX Archive Network},   urldate      = {2006-10-01},   label        = {CTAN},   langid       = {english},   langidopts   = {variant=american}, } @misc{google,   title        = {Google},   date         = 2007,   url          = {http://www.google.com},   urldate      = {2007-10-01}, } @misc{hotmail,   title        = {Hotmail},   date         = 2008,   url          = {http://www.hotmail.com},   urldate      = {2008-10-01}, } @misc{yahoo,   title        = {Yahoo},   date         = 2009,   url          = {http://www.yahoo.com},   urldate      = {2009-10-01}, } @misc{aol,   title        = {AOL},   date         = 2010,   url          = {http://www.aol.com},   urldate      = {2010-10-01}, } @misc{altavista,   title        = {AltaVista},   date         = 2011,   url          = {http://www.altavista.com},   urldate      = {2011-10-01}, } \end{filecontents*} \usepackage[utf8]{inputenc} \usepackage[backend=biber,defernumbers=true,style=ieee]{biblatex} \bibliography{\jobname}  \begin{document}  \section{Section 1} \begin{refsection}  Citing some stuff here: first \cite{ctan}, then \cite{google}, and finally \cite{hotmail}.  \printbibliography[sorting=none,section=\therefsection,resetnumbers=true]  \end{refsection}  \section{Section 2} \begin{refsection}  Citing some stuff here: first \cite{yahoo}, then \cite{aol}, and finally \cite{altavista}.  \printbibliography[sorting=none,section=\therefsection,resetnumbers=true]  \end{refsection}  \end{document}   Output: Why do people omit the definite article? I'm used to always hearing or seeing a  before certain nouns.  Yet on certain occasions the article is totally omitted, and it bothers me.  I'm wondering what the justification for omitting the article is, especially when the definite article would seem to be required, or if it is just bad English either on the part of the individual in question or more likely by tradition.  The most frequent place I hear this is at the doctor or dentist's office. In every one I have ever visited, the receptionist or assistant always says things like "Doctor will see you shortly" instead of "The doctor will see you shortly."  The wikipedia article linked above says this: "A definite article indicates that its noun is a particular one (or ones) identifiable to the listener".  In the case of a clinical setting, I know who the doctor is, especially if this is not my first visit.  The people in the office know the doctor even better than I, so it would seem to be inappropriate to omit the article. Even the indefinite article would be incorrect. It further says, under "Zero article":  "In languages having a definite article, the lack of an article specifically indicates that the noun is indefinite."  Since the noun is not indefinite, why are they omitting the article?  Another place I see the article omitted is with the word "bar".  Bartenders apparently don't say "I tend the bar" they say "I tend bar".  Unless a bartender works in multiple bars, it would seem like an article would be required.  Furthermore, "the bar" can mean any bar a person goes to, so even in a case like , it seems like the word "the" should be in the sentence.  The only thing I can think of in this case is maybe the speaker doesn't want to confuse the listener into thinking they work in the legal field.  Is this just a bad habit, a historical corruption or tradition, or is there really a valid reason (or perhaps more than one) for these omissions? how to change my hostname?
