What formula should be used to determine "hot" questions? What's the difference between !, %, and @ in replacement tokens? What to do about a 2-year-old who won't sleep without someone else in the room? My 2-year-old son won't fall asleep without having someone in his room with him. He doesn't want to be touched or held. He just wants you to sit in the chair. And after he does go to sleep he wakes up about 4 to 5 hours later, crying and screaming and is out of his bed and by the door. I go to him and give him a hug and put him right back in his bed. If I walk out he screams and won't go back to sleep for the rest of the night. If I stay he goes right back to sleep. But he wakes right back up when I walk out of his room.   I'm at a loss as to what to do. I've tried lots of stuff and nothing seems to work. It's almost as if he is having separation anxiety. I dont know what to do. Please help. Why doesn't matter pass through other matter if atoms are 99.999% empty space? The ghostly passage of one body through another is obviously out of the question if the continuum assumption were valid, but we know that at the micro, nano, pico levels (and beyond) this is not even remotely the case. My understanding is that the volume of the average atom actually occupied by matter is a vanishingly small fraction of the atom's volume as a whole. If this is the case, why can't matter simply pass through other matter? Are the atom's electrons so nearly omnipresent that they can simultaneously prevent collisions/intersections from all possible directions? Book recommendations Every once in a while, we get a question asking for a book or other educational reference on a particular topic at a particular level. This is a meta-question that collects all those links together. If you're looking for book recommendations, this is probably the place to start.  All the questions linked below, as well as others which deal with more specialized books, can be found under the tag  (formerly ).  If you have a question to add, please edit it in. However, make sure of a few things first:   The question should be tagged  It should be of the form "What are good books to learn/study [subject] at [level]?" It shouldn't duplicate a topic and level that's already on the list   Related Meta: When should end punctuation go inside quotes? Could humans choose to establish fibre digesting colonies in our guts? Humans don't digest fibre, and nor do any animals, but some creatures have micro-organisms (bacteria, I'm guessing) in their gut which digest fibre for them.  My question is, could humans take some sort of pill and establish our own fibre-digesting colonies in our intestines?  Has this been tried?  Supposing it could be done, would you suppose it would have any negative effects on our health?  (i.e.. would those whose gut digested fibre for them be stuck on a low-fibre diet?).    Purpose of question: just wondering.  It would be cool to be able to eat bark. I have an equation like this:     \begin{align}       P(A \cup B) = \sum_{\omega \in A \cup B} P(\omega) = \sum_{\omega \in A} P(\omega) + \sum_{\omega \in B} P(\omega)       = P(A) + P(B)     \end{align}   For some reason, LaTeX is automatically labeling the equation. How do I turn that off? Secondly how do I write something in LaTeX on this site. I tried enclosing in '$' but it doesn't work. How to use paging in a WFS query? I am running a GetFeature request against a WFS server which does not support to download all data at once. Can I use ogc:PropertyIsGreaterThanOrEqualTo to split the dataset into chunks at download them step by step? I wonder how I can construct the actual URL to include the paging filter. Here is what I tried:  http://example.com/wfs.aspx?request=GetFeature&amp;service=WFS&amp;version=1.1.0 \ &amp;typeName=example:example&amp;maxFeatures=50000 \ &amp;FILTER=&lt;ogc:Filter xmlns:ogc="http://www.opengis.net/ogc"&gt; \ &lt;ogc:PropertyIsGreaterThanOrEqualTo&gt;&lt;ogc:PropertyName&gt;OBJECTID&lt;/ogc:PropertyName&gt; \ &lt;ogc:Literal&gt;50000&lt;/ogc:Literal&gt;&lt;/ogc:PropertyIsGreaterThanOrEqualTo&gt;&lt;/ogc:Filter&gt;   This is not a valid URI though... That's why uri-encoded the filter part:  http://example.com/wfs.aspx?request=GetFeature&amp;service=WFS&amp;version=1.1.0 \ &amp;typeName=example:example&amp;maxFeatures=50000 \     &amp;FILTER=%3Cogc%3AFilter%20xmlns%3Aogc%3D%22http%3A%2F%2Fwww.opengis.net \ %2Fogc%22%3E%3Cogc%3APropertyIsGreaterThanOrEqualTo%3E%3Cogc%3APropertyName%3EOBJECTID \ %3C%2Fogc%3APropertyName%3E%3Cogc%3ALiteral%3E50000%3C%2Fogc%3ALiteral \ %3E%3C%2Fogc%3APropertyIsGreaterThanOrEqualTo%3E%3C%2Fogc%3AFilter%3E   This actually works.

Lightning Web Components: navigate to the 'new' object page passing in specific record type Id? I am using LWCs to display lightning cards in a list.  The list shows information about Programs.  Each Program card has a button, and this button needs to take the user to the 'new object' screen of the Application object.  Here is my code:   applyToProgram(event) {     // The recordTypeId is coming from the .html     // I have verified that the value is correct.     var rtId = event.target.id;      // How do I use rtId below?     this[NavigationMixin.Navigate]({         type: 'standard__objectPage',         attributes: {             objectApiName: 'Application__c',             actionName: 'new',             nooverride: '1',             recordTypeId: rtId  // This does not work         }     }); }   This is not working.  The user is presented with the 'new object' screen for the object's default record type and NOT the one specified in rtId.  I tried putting 'nooverride' and 'recordTypeId' in the state:{} argument, and I also renamed 'recordTypeId' to just 'recordType'.  None of these worked.  Can anyone help me with the correct syntax?  Is this even possible in LWCs?  Thanks, Jeff Where can I get a device with 'Ubuntu for phones' pre-installed? Canonical has recently announced , which is Ubuntu with a specific interface for mobile devices.  Where can I get phones with this version of Ubuntu pre-installed?

The private key length is 128 bits, it does not change. The "word" is literally one short word.  Assuming an attacker knows "word" and "output" for multiple words (e.g., dog = "dsfwrw3r3r323211", cat = "3erwerwetwewer"):   Is it significantly easier for an attacker to identify the private key by brute force with the above word/output pairs, as compared to a situation where they do not have those pairs? Is this brute force vulnerability (with word/output pair knowledge) an actual security concern? Smaller vs. less vs. lesser I am confused as to some of the vocabulary that can be used to compare numbers and quantities, and would very much appreciate some clarification.   I suppose it is safe to say that 1 is smaller than 2.   Can I also say that 1 is less than 2, and if so, which form is preferable?   It seems that saying that 1 is lesser than 2 is uncommon - but is it incorrect?   Finally, -2 is clearly less than -1, but is it true that -2 is smaller than -1? (If I have 2$ of debt, then I would say that I have less money than if I had 1$ of debt, but I would also say that my debt was larger, not smaller). "This site is all about getting answers.

The Turkish e-visa is valid for a period of 180 days and allows you to stay for a maximum of 90 days.

I'm having trouble with the OpenLayers Plugin of Qgis and the map composer:  If I create an OSM-background layer and if I want to export this, the OSM-Layer looks perfectly all right in the normal qgis program window. But in the map composer and after export the layer has shifted relatively to my other shape layers (EPSG:32633 - WGS 84 / UTM zone 33N).  The second thing is that the output resolution of the exported osm-layer is very, very poor.   A really bad way of getting around this whole trouble would be to increase the screen resolution and make a screenshot of the map composition window of qgis. But I don't think this would be very professional. It also would cause a lot of pain :)   I'm using Qgis 1.8.0-Lisboa under Linux. The openlayers plugin is version 0.92. Most games build on other games' successes and many are downright clones. Where is the limit of imitation before legal issues come into play? Is it down to literary or graphic work like characters and storyline that cause legal problems, or can someone actually claim to own gameplay mechanics?  There are so many similar clone games out there that the rules are probably very slack or nonexistent, but I'd like to hear the views of more experienced developers / designers.
