I have just pulled up my old ceramic tiles from my bathroom an there is the thinset on the subfloor an some grout left on it. Do I need to clean that before putting new thinset on it? | I will be installing some new 12x12 tiles in two bathrooms approx 25 sq/ft each. When I pulled up the old tiles, there was no thin set that had made contact with them so the removal was very easy. Now, the thin set on the floor is a different story. I have been chipping away at it by hand in one bathroom to get to the cement floor below and it has been a bugger to get off. Before I attempt to continue this process in the second bathroom, I would like to know if it is absolutely required to do so if it is well adhered to the cement underneath? (It's my hope, obviously, that I can tile over the old thin set as long as it is level and firmly attached.) EDIT: My subfloor is a concrete slab with the thin set on it. It must be chipped away to remove vs. cut and replace sub floor. |

I’m newer to blender, and trying to create a 3D model of a brimmed cap sort of like a ball cap from a scan I took of the exterior using an iPhone app (ScandyPro). I’ve managed to import the .obj file and clean up the exterior (fill holes/inconsistencies in the scan etc). Problem is that it needs an “interior” to look real. Since a caps material is mostly thin fabric, I imagine there’s a way to duplicate the external scan and shrink it slightly, move it down, and to close up the “exterior shell” by connecting it to the exterior - I’m not sure how I would “bridge” the edges between the interior And exterior cleanly and efficiently though. Can anyone confirm if this is the easiest way to accomplish this and point me to the tools to bridge the two meshes together? | So I made this structure by subdividing a plane and elevating parts to make hallways: Then I realized that I wanted to make the walls have a certain thickness.

Often if I am doing something in the terminal I will mistype something and enter something unintended.

I think that for positive natural numbers t and n we have $$ \left(1+\frac{n}{t}\right)^t\ \le\ e^n\,. $$ Is this true? I have constructed a proof of it (which would probably take some lengthy typesetting here, and further I believe that the inequality could be very standard), but I wish to have an independent confirmation from the folks here.

Please, help me find the mistake in this line of thought, or solve the inevitable question at the end. 🙂 suppose there are two facing plates with different charge $Q_1$ and $Q_2$ these two plates are the only thing in the universe because of the charge imbalance, there is electrical energy in the system now I connect the two plates with an ideal conductor of zero resistance the excess charge in one plate goes to the other plate, without dissipating heat at the end there is no more charge imbalance, no more electric energy in the system where did the energy go? | What exactly would happen in the ideal case where a capacitor were to discharge into a wire with zero resistance? Like in here: There is still charge on one plate of the capacitor, which will try to go to the other plate to make $\Delta V = 0$ across the capacitor, so there has to be a current $I$. But as more charge goes to the other side of the capacitor, the more repulsion these will cause to more coming towards them. So I am assuming current cannot just be constant? I am starting from $$ I = C \frac{dV}{dt}, $$ but I know neither $V(t)$ nor $I$. |

In S06E10 "The Winds of Winter", Lord Varys is first seen in Dorne in this scene: And at the end of the episode Lord Varys is seen standing behind Daenerys in the ship: How is this possible? Does Varys have some power that I am not aware of? What is it? | In S06E10 ("") we see Olenna Tyrell in Dorne, conversing with Ellaria Sand about a possible alliance between Dorne and Tyrell. Then suddenly Varys appears saying Fire and blood. What does this mean? It could point to an alliance between Dorne, Tyrell and Daenerys, which seems a reasonable choice, seeing that they both want to go against the Lannisters. But his appearance still seemed rather odd to me, since Varys should still be in Meereen, as we see him sailing on the ships that leave for Westeros with Daenerys later. So how was he suddenly in Dorne? Does this mean that scene was out of chronological order (in which case, was it earlier or later?)? Or does he have some other means for fast travel? Or was this maybe not even Varys? I would not like this question to degrade too much into completely random speculation and hope I just missed something obvious or it isn't as odd for him to be there as I might think.

I am preparing for my C# EXAM. I am confused about the answer to this question: A program can use the IEnumerable and IEnumerator interfaces to do which of the following? a.

According to the $\Lambda$CDM parametrization of the Standard Model of Big Bang cosmology, the universe contains a cosmological constant $\Lambda$ associated with $73\%$ dark energy, $23\%$cold dark matter (CDM) and $5\%$ ordinary matter. I have also read from Kolb and Turner's book that the Cold dark matter leads to a "bottom-up" formation of structure in the universe while hot dark matter would result in a "top-down" formation scenario; since the late 1990s, the latter has been ruled out by observations of high-redshift galaxies such as the Hubble Ultra-Deep Field. $\bullet$ How do we know that the dark matter is cold or nonrelativistic? $\bullet$ What is the percentage of hot dark matter in $\Lambda$CDM parameterization? Is the possibility of dark matter totally ruled out? Addendum Existence of CDM does not rule out existence of HDM. In fact, it is assumed that the dominant fraction of the dark matter is CDM type. But observations only tell us that $23\%$ of the total mass-energy of the observable Universe dark matter. But this information does not tell how much of it is HDM and how much is CDM? The belief is that the the dominant component of the dark matter is CDM but is there an estimate? Is there a physical way to understand/expect why the CDM should be the dominant contribution? Please note There is a typo. I wanted to ask "Is the possibility of hot dark matter totally ruled out?" | Most of the dark matter in the Universe is cold or nonrelativistic which rules out neutrinos as dark matter candidate as they are hot or relativistic.

I tried to work with a list of deques and was not able to to append a value to a single deque by indexing it. It looks like the following: >>> l_deque = [deque([0] * 3, maxlen = 3)] * 5 >>> l_deque [deque([0, 0, 0]), deque([0, 0, 0]), deque([0, 0, 0]), deque([0, 0, 0]), deque([0, 0, 0])] >>> l_deque[0] deque([0, 0, 0]) So far so good. But when I try to append a value to a single deque it appends it to every deque: >>> l_deque[0].append(1) >>> l_deque [deque([0, 0, 1]), deque([0, 0, 1]), deque([0, 0, 1]), deque([0, 0, 1]), deque([0, 0, 1])] I expected something like this: [deque([0, 0, 1]), deque([0, 0, 0]), deque([0, 0, 0]), deque([0, 0, 0]), deque([0, 0, 0])] Do you have an idea where I took the wrong turn? Thanks Edit: Thanks guys, Changing it to >>> l = [deque([0] * 3, maxlen = 3), deque([0] * 3, maxlen = 3), deque([0] * 3, maxlen = 3), deque([0] * 3, maxlen = 3), deque([0] * 3, maxlen = 3)] did the job.

By downloading I obtain these fonts: Adobe Pi Std (regular) Courier Std (regular, bold, italic, bold-italic) Minion Pro (regular, bold, italic, bold-italic) Myriad Pro (regular, bold, italic, bold-italic) Is it legal to embed these fonts in a PDF and distribute that PDF? | Suppose, I am creating a logo in a vector graphics editor (for example ) and I use there the font which cannot be freely distributed (for example which can be obtained by downloading Adobe Reader).

I have trouble declaring a two-dimensional list in Python. Below are two different matrices; A and R. When changing the content of a single cell I am successful in the R-matrix, but not so much in the A-matrix, as the value-input affect the entire column and not only the single cell.

I am exploring the world of the REST API for the first time, I have already had to deal with it through the use of Slim, but now I want to be a homemade solution, considering that I don't need any framework for make a simple Rest Api. What I have done is create a page like this: <?php $method = $_SERVER['REQUEST_METHOD']; $request = explode("/", substr(@$_SERVER['PATH_INFO'], 1)); switch ($method) { case 'PUT': echo "PUT"; break; case 'POST': echo "POST"; break; case 'GET': echo "GET"; break; case 'DELETE': echo "DELETE"; break; default: handle_error($request); break; } My goal is to implement an access token, I think passing it in the header but I'm not sure (I'm looking for a secure mode). However if I run this from the command line: curl -X GET http://localhost/v1 I get GET, just to give an example of how it should work. And so for all other inquiries. Now the real question is: how can I call the methods in the switch only if I passed a token? For example, at the top of the page will be performed control will be carried out such a check: if(!isset($_SERVER['AUTH_USER'])) { exit('TOKEN not provide'); } Another question is how to pass the token via curl? Because if I do it through ... I can read the header via curl but how would it work? UPDATE: As mentioned by @Paradoxis I've tried with: url http://localhost/v1 -H "Authorization: <token>" but seems that I fail to take the header. I spend my time to understand why the header isn't passed, so in my code I've add this line: print_r(apache_request_headers()); and this is the result: Array ( [Host] => localhost [User-Agent] => curl/7.46.0 [Accept] => */* [Authorization] => <token> ) How you can see in the request_headers I can see correctly in the header, but I can't catch it through the use of $_SERVER['Authorization'] or $_SERVER['HTTP_Authorization'] | What does RESTful Authentication mean and how does it work?

I have heard that the Voyager spacecrafts received gravitational boosts from some of the planets before they left the solar system. How is this achieved? Since we have to conserve energy it seems that whatever speed is gained due to gravity would then be lost as the object flys away from the planet.

Consider now the maneuver known as a (also gravity assist) used by space probes such as the .

This feature request would, in my opinion, be supportable if the majority of reviewer votes were going to single-vote questions. I cannot (I think) actually find these numbers. If this is the case, the majority of the work is going to an ever-increasing queue, and proportionally fewer votes are being resolved. Note there are other distributions that could help get in this direction without being a strict ordering, like weighting the chance a given question is surfaced to a reviewer by the number of votes. However, for discussion purposes I thought I'd keep it simple. Usual apology if this has actually been addressed. Search is sad-making. |
I am a bit new to javascript, i was just trying the below snippet: _getUniqueID = (function () { var i = 1; return function () { return i++; }; }()); s = _getUniqueID(); console.log(s); // 1 console.log(_getUniqueID()); // 2 I was under the impression that i would have to do s() to get 1 as the result and i was thinking that _getUniqueID() returns a function rather than execute the funtion inside it. Can somebody explain the exact execution of this function please ? | I'm new to both JavaScript and . In YUI library examples, you can find many uses of this construct: (function() { var Dom = YAHOO.util.Dom, Event = YAHOO.util.Event, layout = null, ... })(); I think the last couple of parentheses are to execute the function just after the declaration. ... But what about the previous set of parentheses surrounding the function declaration? I think it is a matter of scope; that's to hide inside variables to outside functions and possibly global objects. Is it? More generally, what are the mechanics of those parentheses? |
In the answer to and it is recommended that you cite an idea or useful answer for your research work on StackExchange. Now, if you have asked a question requiring a walk-back mathematical process (lets assume its a contribution) using fundamental knowledge to walk-back, if you do cite in this case, how do you keep the privacy of your account name? Since, people would check the answer and could look into the account history of the questioner and the answerer. Also, these StackExchange websites are linked and it seems that not everyone would like that for privacy reasons. So how could this be managed appropriately? Note: This is a modification of an existing question marked as duplicate. | Sometimes we may ask questions on stack exchange or online forums wherein the response is helpful or even essential to a piece of work that gets published in an academic journal. If this occurs, how should credit be given to those involved in the exchange? Should they all be included as authors? Should a link to the forum be included as a reference in the paper? Once something is in a stack exchange or forum, it's "published". Perhaps in the future, the current peer review model will transform into people writing blogs and posting in forums and databases. But for now, how might this issue be dealt with while forums, blogs, etc coexist with journals? |

A reach weapon adds 5 feet to your reach making it 10 feet. If you are holding a 2-handed reach weapon (eg a glaive) with 2 hands and someone moves from 5 feet away to 10 feet away do you still get an opportunity attack? Or because you are holding the weapon are you unable to use an unarmed strike for opportunity attacks? | Assume I wield a Whip in one hand and a dagger in the other. If a creature moves from 5ft to 10ft it has technically moved out of my reach (dagger), but at the same time it is still inside my reach (whip). When does it provoke opportunity attacks from me?

I recently installed Ubuntu on my computer on a separate (internal) hard drive from Windows, and everything works fine except it will not recognize devices plugged into the rear USB ports on my computer.

I was at the airport last friday and there were some nice sun light rays, although not much of a good spot to take a picture. What weirds me out every time I see them is that they look as if coming from a ball of light pretty much right behind the clouds.

I have the website content on the centos 5 server saved in Dropbox. In that way i can easily access them without having to use ftp. However sometimes it happens that Dropbox chmod's random updated files to 666. This causes the error: "this file is group writeable" Why does it do that and how should i prevent it? Should i maybe create a cron script that looks for chmod 666 files and automatically corrects them? Still that would be a lousy fix though.... | I have two machines, a Mac and a PC running Linux, that I am trying to keep a certain file synced between using Dropbox. One of the files that I am syncing needs to be writable by another user (different UID on the same machine, not referring to another dropbox user) besides myself. To be more specific, this other UID is actually a daemon. So, either the file needs to be owned by that other user, or else write permission is needed for "group" and/or "other". Initially I have set it up this way on both machines. In addition, the directory containing the file is already owned (chmod 777) by the user that needs to have write access to the file. However, whenever the file gets synced from one box to another, it appears that Dropbox completely ignores both sets of permissions, and changes the permissions on the newly updated file to be owned by me with permissions 0644 (rw for me, r for everyone else). If the file isn't owned by me it even changes ownership back to myself! As a result, the other user no longer has write permissions until I manually go in and re-chmod the file. Additional things I have tried that have not worked: made sure the user account (for the "other user") on both machines has the same UID. Not sure why this would be necessary, since my primary account doesn't have the same UID on both machines. chmod u+s <dir> and chmod g+s <dir> where is the directory containing the file in question. changing ownership of the file to the other user and placing it outside the Dropbox directory, and creating a symlink to the file in the Dropbox directory. Dropbox actually deletes the symlink, leaves the original file (outside the Dropbox directory) unchanged, and creates a new copy of the file where the symlink used to be! How can I set things up so that my permissions and/or ownership are preserved? |
If $f_n$ and $f$ are integrable, $f_n \to f$ a.e., and $\int |f_n| \to \int |f|$, then $\int |f_n-f| \to 0$. How can I prove this?

Suppose that $\{f_k\} \subset L^p$ (the domain here does not necessarily have to be finite), $f_k \to f$ almost everywhere, and $\|f_k\|_{L^p} \to \|f\|_{L^p}$.

Is it bad practice to do so? | I am using hook_theme_suggestions_HOOK() to implement a custom template file in my drupal 8 website like below. /** * Implements hook_theme_suggestions_HOOK(). */ function mymodule_theme_suggestions_page(array $variables) { $template_suggestions = array(); // This is used to display only $content. if (isset($_GET['ajax']) && $_GET['ajax'] == 1) { $template_suggestions[] = 'page__ajax'; } return $template_suggestions; } Above code is working fine and I can add template page--ajax.html.twig inside my current active theme and changes in template is reflecting in page. But when I put that file inside my module itself file is not detecting and changes not reflecting in page and taking default page.html.twg template file. How can I provide default template file within my module itself? |
Please don't mark it as duplicate. I am using Blowfish Algorithm to Encrypt and Decrypt a Contents in a File.

This is a javascript, I have no experience in coding unfortunately. So I need your help. I'm trying to put a 10 sec delay on this code document.getElementById('example').click(); The idea is that I want a link to be click after 10 secs. I tried putting 10000); at the end of the code but it makes the code not work.

Some images are to lay on top of others. To make it simple, say I want a blue square, with a red square in the upper right corner of the blue square (but not tight in the corner). I am trying to avoid compositing (with ImageMagick and similar) due to performance issues. I just want to position overlapping images relative to one another. As a more difficult example, imagine an odometer placed inside a larger image. For six digits, I would need to composite a million different images, or do it all on the fly, where all that is needed is to place the six images on top of the other one. |
For example, in this paper: How can we get the same or similar text font and math font in LaTex? | Is it possible to identify the font used in a specific document/picture? Answers to this question should identify: Possible methods to do this (perhaps one answer per method) and adequately describe how to use it (as opposed to merely stating it); Ways of finding the identified fonts, if possible (free or not); and Any prerequisites associated with the method used, if required (for example, "In order to use method X, your document has to be in format Y"). This question is meant as an FAQ, based on an . Its aim is to facilitate the community with the general procedures involved in font identification. Similar cases are solved on a per-usage basis on 's tag. |
I have an old Toshiba Specs are: processor: 1.70 GHz Intel® Pentium® M processor 735 hard disk: 60 GB system memory: 512 MB (although I am in the process of buying an extra 1G ram for it) graphics: nvidia GeForce Go 6600, 128MB My laptop still runs on XP 32bit and is used mostly for working on my PhD - lots of typing, bit of browsing, lots of article reading (PDFs) and listening to music.

If I have some code: code1 class Foo: code2 def spam..... code3 for code4..: code5 x() Where is x found? Some possible choices include the list below: In the enclosing source file In the class namespace In the function definition In the for loop index variable Inside the for loop Also there is the context during execution, when the function spam is passed somewhere else. And maybe pass a bit differently? There must be a simple reference or algorithm somewhere. It's a confusing world for intermediate Python programmers. |
Checking to see if a one-hour layover is enough time, flying JetBlue from Newark to LAX, code share flight on Hawaiian from LAX to HNL.

I have simulated the circuit with the following values. VDD = 1.8V, Vin is a sine wave with fin = 450MHz, pin = -5dBm, L1 = 12.5nH, C1 = 10pF, RL=50 ohm. I also gave a biasing dc voltage at the gate of MOSFET as 1V. I got the following graph after simulation. The red graph is the input sine wave. The yellow graph is the current at the drain of MOSFET and the green one is the voltage at the drain of MOSFET. But I am not exactly getting what the graph means or how to interpret it? If I am using it as a power amplifier how can I improve the output values of voltage and currents? | In the power amplifier circuit shown if the input is an RF sine wave, with VDD=1.8V and Vgs = 1V, what will be the waveform at the drain of the MOSFET - sine or square wave? Is it possible to get a sine wave at the drain? |
So I remember this show that was based in a space station (more like a hub with no political affiliations) some of the main characters were doctors, and the thing today's sticking out to me is that everyone had to have a gem implanted I their hand and the colour of that gem dictated who you could marry/date. This was a live action series, colour, in America. Started in like the 90s. No idea how long it ran. Sorry I'm not giving a lot of information. Edit: So it might be Island City, I'm going to watch the whole thing to make sure, but I really appreciate you guys thinking about this. I guess I can't trust my little kid memories. Final edit! That was it! Thanks everyone for the help. Convinced that they need to remake it. It was awesome. | I'm trying to figure out the name of a movie I saw on TV as a kid, in the mid-to-late 90s, in the US, in English, on daytime TV. I remember it being kind of Starship Troopers-esque, but everyone had these glowing lights in their chests. They glowed in different colored patterns, and I think it had something to do with whether you were attracted to someone or not (I was probably like 7 when I saw it, I didn't really understand the context of that part yet). |
I am running latest Kubuntu 20.04 with dolphin file manager version 19.12.3. However the latest stable version is already available as 20.04.3 Therefore, I am wondering if the release cycle is different as officially I couldn't download it and latest available version is still locked to the older version of 19.12.3 I realised that i could possibly simply fetch the latest version from flatpak as well However, I am interested to know why it was not available to download officially. Also, I would like to know the lifecycle of latest stable version of KDE packages to be released for Kubuntu/Ubuntu repository and when would it be available to download officially?

I am using QGIS 3.14. I downloaded world cities name kml, which has markers symbol on every label. I want to display the symbol only on every name which rendered / displayed on exported file. Currently, all symbol are displayed even though the cities name are not displayed, so it will only show empty marker without label on it.

Im holding a philippine passport whith c1 visa (issued by US embassy) a transit visa that can transit to any airport in USA , can i use my C1 visa to transit to Japan or do i still need to get a transit visa to pass through their airport in japan? my last destination will be in Manila,Philipines. Thanks in advance. | I’m a Filipino citizen. My flight goes from Vancouver to Manila via Tokyo Haneda. I will arrive in Japan at 6pm then depart at 9am the next day. I'm not planning to go out of the airport during my layover, so I don't see a need to have a transit visa. However, I called the Consulate-General of Japan here in Canada, and they asked me to get a transit visa. Then I called the Ministry of Foreign Affairs in Japan and asked them the same question.. at first, they told me I don’t need a visa as long as I stay inside the airport, but when I told them that the Consulate-General of Japan in Canada asked me to get a visa, they also asked me to get one. I'm so confused. I would like to know your knowledge or experience regarding this. |
