Gas oven heated from the bottom I moved to a new place and I have an ancient gas cooker that I can't replace just yet. As the heat source is at the bottom of the oven (rather than the top), would a baking stone help even out the heat and help stop burning?   I’ve found lots of information referring to the beauty of baking stones when using an oven with the heat source at the top but cannot find anything that helps me.
Use of pizza stone in gas oven I have a new gas kitchen stove.  The oven seems to burn so easily. I have a thermometer in there and it is registering the temp that I have the oven set on.  I have seen where people have used a pizza stone to even out the heat.  I want to know if you place a rectangle pizza stone directly on the bottom of the oven or should it be placed on a rack on the lowest setting?  I would appreciate replies from anyone who has used this and if it had helped the problem
How do you find the modular inverse of $5\pmod{\!11}$ Make an object invisible to a specific camera? (Cycles) Indicate How Trustworthy the UpVotes Are How do I Enqueue styles/scripts on Certain /wp-admin Pages? I have two simple functions that load stuff using  and , something like these:  function admin_custom_css() { wp_enqueue_style( 'stylesheet_name', 'stylesheet.css') };   function admin_custom_js  { wp_enqueue_script( 'javascript_file', 'script.js') };   ... and a few admin pages, created with  and   function my_menu() {    add_menu_page('Page 1', 'bar', 'something', 'else', 'foo');    add_submenu_page( 'theme_menu', 'Subpage 1', 'Subpage', 'something', 'else', 'foo');  } add_action('admin_menu', 'my_menu');    How do I load my two functions only on these pages?  Right now I'm using:  add_action('admin_init', 'admin_custom_css' );  add_action('admin_init', 'admin_custom_js' );     But it loads my files on every admin page, which is not nice at all.  Can I do this via one simple line in functions.php or have to enqueue them within my pages separately (I prefer the first option strongly, since I'd have to edit a lot of admin-page-creating-functions).  Thanks! So I was configuring VS code on my Notebook when suddenly I noticed that my interface font got really small on my desktop, terminal and files. I use Gnome Tweaks Tool to increase my scaling factor to 1,15 , but, even though it was active, the font stayed tiny. The solution I found was moving my scaling factor, which instantly fixed my font issue, however, every time I restart my Notebook the font gets tiny again and I have to repeat the process. I tried reseting my font configuration using this command, but had no success. gsettings reset org.gnome.desktop.interface text-scaling-factor  I also tried using the command dconf reset -f /  Finally, I tried using dconf-editor, but still had no success altering the font rendering DPI or changing the scaling factor. All of the steps I mentioned fixed my fonts temporarily, but the issue still persists when I restart my Notebook I am out of ideas and even considered getting a fresh Ubuntu install by now... My video card: NVIDIA GeForce GTX 1050 GPU What is the value of $i^{i^{i^\ldots}}$? What is the value of $i^{i^{i^\ldots}}$?   My effort is the following: If $z, \alpha \in \mathbb{C}$ with $z \neq 0$ then we can write $z^{\alpha}=e^{\alpha \log z} = e^{\alpha [ \log |z|+i \text{ Arg z} + 2 \pi i m]}$ where $ m=0, \pm 1, \pm 2, \ldots$  and Arg z is the principle argument of the complex number $z$. But in above expression we don't have the finite no of exponents, so I am not sure how should I use this formula to the solve above problem. Thanks and Regards! Make cd automatically ls I find that I often do the following:  %&gt; cd bla/bla %&gt; ls   I would like it that whenever I cd into a directory it automatically does an ls.  I fiddled with my .bashrc for a while, but couldn't figure out how to make it happen. So this has been an on-going saga the last few days, and I've already posted several related questions here, and I am feeling quite defeated.  I have/had a beautiful 16" cast iron dutch oven from Cabelas. I took it out for a test spin the other night (I had completed all seasoning steps that the Google Gods recommended). Then:   I tried (and failed spectacularly) to cook a pork roast in it, but cooked it at way too hot a temperature and burned/charred/fused the animal fats/juices into the oven, whereby it basically baked into the cast iron (related question ) I tried cleaning/scrubbing it with coarse-grained salt -> did nothing Then I tried cleaning it with dishwashing liquid + salt -> did nothing Then I let the whole thing soak in a vat of a 50/50 mixture of water + white vinegar -> took all the tarry slude off, stripped some seasoning off (revealing bare iron), but in 80% of the burned/charred areas, still did nothing Then I went to town on it with a steel wool and salt and dishwashing liquid and was left with some smooth, properly seasoned surfaces, and some more areas stripped down to bare metal I decided to just re-season it. So I scrubbed it one last time (about 1 hour ago) with a steel wool and some water, got all the rust and remaining crud off (finally), and built a fire. I placed it on the hot coals of the fire and let it sit there for 15 mins. My intention (whether misled or not) was to burn off all the remaining water from when I had previously washed/scrubbed it, then let it cool off, then season it with oil, and then bake it for a few hours.   So I just took the oven off the fire and opened the lid...and the entire inside is covered in rust. An hour ago there was none. When I put the oven into the fire 15 mins prior, there had been none (yes, I checked) This just came out of nowhere.  I'm ready to give up, unless anyone can offer some concrete set of steps for me that will salvage this $100 rust bucket. How can I get rid of the rust and then re-season this before more rust sets in? Meh...

How can you derive this? how to Query parent to child I have process in salesforce in such a way opportunity we can relate this opportunity to this lookup field parent_opportunity__c . Which relates opportunity to other parent opportunity.  I want to write a query parent to child :  select id,(select id from opportunity where parent_opportunity__c!=null) from opportunity where parent_opportunity__c=null   I have worked with different scenarios i cant able to crack it  select id,name,(select id,name from parent_opportunity__r) from opportunity this is showing error and   select id,name,(select id,name from opportunity) from parent_opportunity__c this is also error How do I tell if matrices are similar? I'm building a quick csv from a mysql table with a query like:  select DATE(date),count(date) from table group by DATE(date) order by date asc;   and just dumping them to a file in perl over a:  while(my($date,$sum) = $sth-&gt;fetchrow) {     print CSV "$date,$sum\n" }   There are date gaps in the data, though:  | 2008-08-05 |           4 |  | 2008-08-07 |          23 |    I would like to pad the data to fill in the missing days with zero-count entries to end up with:  | 2008-08-05 |           4 |  | 2008-08-06 |           0 |  | 2008-08-07 |          23 |    I slapped together a really awkward (and almost certainly buggy) workaround with an array of days-per-month and some math, but there has to be something more straightforward either on the mysql or perl side.   Any genius ideas/slaps in the face for why me am being so dumb?    I ended up going with a stored procedure which generated a temp table for the date range in question for a couple of reasons:   I know the date range I'll be looking for every time The server in question unfortunately was not one that I can install perl modules on atm, and the state of it was decrepit enough that it didn't have anything remotely Date::-y installed   The perl Date/DateTime-iterating answers were also very good, I wish I could select multiple answers!

I was supposed to find all possible Jordan canonical forms of a $5\times 5$ complex matrix with minimal polynomial $(x-2)^2(x-1)$ on a qualifying exam last semester.  I took the polynomial to mean that there were at least two 2's and one 1 on the main diagonal, and that the largest Jordan block with eigenvalue 2 is $2\times 2$ while the largest Jordan block with eigenvalue 1 is $1\times 1$.  Did I miss any matrices or interrupt the minimal polynomial incorrectly?  \begin{pmatrix}   2 &amp;1  &amp;0  &amp;0  &amp;0\\   0 &amp;2  &amp;0  &amp;0  &amp;0\\   0 &amp;0  &amp;2  &amp;1  &amp;0\\   0 &amp;0  &amp;0  &amp;2  &amp;0\\   0 &amp;0  &amp;0  &amp;0  &amp;1 \end{pmatrix}  \begin{pmatrix}   2 &amp;1  &amp;0  &amp;0  &amp;0\\   0 &amp;2  &amp;0  &amp;0  &amp;0\\   0 &amp;0  &amp;2  &amp;0  &amp;0\\   0 &amp;0  &amp;0  &amp;2  &amp;0\\   0 &amp;0  &amp;0  &amp;0  &amp;1 \end{pmatrix}  \begin{pmatrix}   2 &amp;1  &amp;0  &amp;0  &amp;0\\   0 &amp;2  &amp;0  &amp;0  &amp;0\\   0 &amp;0  &amp;2  &amp;0  &amp;0\\   0 &amp;0  &amp;0  &amp;1  &amp;0\\   0 &amp;0  &amp;0  &amp;0  &amp;1 \end{pmatrix}  \begin{pmatrix}   2 &amp;1  &amp;0  &amp;0  &amp;0\\   0 &amp;2  &amp;0  &amp;0  &amp;0\\   0 &amp;0  &amp;1  &amp;0  &amp;0\\   0 &amp;0  &amp;0  &amp;1  &amp;0\\   0 &amp;0  &amp;0  &amp;0  &amp;1 \end{pmatrix}  \begin{pmatrix}   2 &amp;0  &amp;0  &amp;0  &amp;0\\   0 &amp;2  &amp;0  &amp;0  &amp;0\\   0 &amp;0  &amp;1  &amp;0  &amp;0\\   0 &amp;0  &amp;0  &amp;1  &amp;0\\   0 &amp;0  &amp;0  &amp;0  &amp;1 \end{pmatrix} The existence of the empty set is an axiom of ZFC or not?

Maximum value of $\sin A+\sin B+\sin C$? What is the maximum value of $\sin A+\sin B+\sin C$ in a triangle $ABC$. My book says its $3\sqrt3/2$ but I have no idea how to prove it.   I can see that if $A=B=C=\frac\pi3$ then I get $\sin A+\sin B+\sin C=\frac{3\sqrt3}2$. And also  maximum is attained for $a=b=c$. But this does not give me any idea for the proof.  Can anyone help?
