I have been taught that the pronunciation the letters after /s/ should be changed. e.g.  school:  ch reads /g/ (as in grow) stay:    t reads /d/ (as in day)  But I'm not sure these words:   describe:  the c after des, /k/ or /g/? discrete:  the c after dis, /k/ or /g/? system:    the t after sys, /t/ or /d/? execute:   the c after  exe, /k/ or /g/?   Which is the correct pronunciation, and when shall I change, when not?  UPDATE: Matt asked me why not get them in dictionary, but the changed pronunciation won't present in dictionary. See:  stay    /stei/, it's t, not d school  /sku:l/, it's k, not g
Does the word discharge sound more like /dɪstʃɑːʳdʒ/ or /dɪsdʒɑːʳdʒ/? How about exchange or disproportion? Do they sound more like /ɪkstʃeɪndʒ/ or /ɪksdʒeɪndʒ/? /dɪsprəpɔːʳʃən/ or /dɪsbrəpɔːʳʃən/? I know the word student which commonly sounds like /sdjuːdənt/. and the dictionary says its IPA transcription is /stjuːdənt/.
How do I get horizontal lines to the left and right of a heading in Microsoft word? In Word 2007 I want to put a heading in the center of a line with a horizontal line to the left and to the right of the text.  The line must not cross through the text. I have tried using autoshapes and lines - but then the lines move each time I press Enter or &larr; Backspace and I have to put them in place again manually.  At Borders and Shading there is an "Insert horizontal line" option, but this gives me a solid line from the left to the right of the page and I cannot insert text anywhere on it or in it.    The final product should look something like this:     -------------------------  Heading ------------------------- xslt processing on select attribute on apply-templates All of a sudden, without any change in the index.html, our site is showing up in Google search results (on multiple browsers and devices) with Google Preview text that, instead of giving a summary of our site, now says:     Your browser does not currently recognize any of the video formats available. Click here to visit our frequently asked questions about HTML5 video.     We have a YouTube embed on our homepage that does include an html5 parameter in the media URL link in the embed, but there are no issues playing the video with any browser and device we can find.  What would suddenly cause this text to appear in Google search results?   We are using the  tags as the metatags in the &lt;head&gt; of our webpage and do indeed have title and description tags.    To mimic the behavior of Googlebot, I installed Windows on a VM and got Chromium 41 running. I get the same Google Preview text with the html5 video message when the site comes up in Google search results using this browser.    When I view the site in Chromium 41, I see the YouTube embed and it renders on the page and plays with no issue, just as with all other browser and devices we've tested on. The only time we see this message is in the Google search results, not on our actual site. We were given the following problem as an assignment, we proved the converse in class for prime numbers; however, we can't use the assumption that $\operatorname{gcd}(a,b) = 1$.  So I am struggling to think of my first possible move.  We are given $ar + bs = 1$, the only think I can think of is let $d$ be a common divisor or $ar + bs$ and then show that the $d = 1$.  However, I am not really sure how to do that.  If anyone could just give me a hint or two to nudge me in the right direction I would be appreciative. What does "at 19.45 hours" mean? I was reading a book and this sentence seemed a little odd to me:     At approximately 19.45 hours the two men rose, stretched and yawned. They picked up their gear and stood at the door, ...   What does the first part mean? If it's the exact time, shouldn't it be 19:45? And if it's duration, shouldn't it be "After 19.45 hours"?  (The story here happens at an airbase, if it's of any relevance)    Edit: The book I've quoted is this:   by John Creed.   The author is Irish and the text is set in northern England/Ireland. How can I enable "clicklock"? Does this email mean that I have been granted the visa? MySQL string replace How to know the usage of undocumented function like LinearAlgebra`BLAS? I have a PHP script that can encode a PNG image to a Base64 string.  I'd like to do the same thing using JavaScript. I know how to open files, but I'm not sure how to do the encoding. I'm not used to working with binary data. Probability of two uniform random numbers being more than $\frac{1}{2}$ apart Two numbers are chosen randomly and independently from the unit interval $(0,1)$.  What is the probability that they differ by more than $\frac{1}{2}$? Hint: Think of the $2$ numbers chosen as coordinates in the Cartesian plane. Draw a square with vertices at $(0,0)$,$(1,0)$,$(1,1)$, and $(0,1)$. Allowable choices for the $2$ points lie below the line $y=x-\frac{1}{2}$ or the above $y=x+\frac{1}{2}$. Find the combined area of these regions.  I need help on this. I know what $y=x-\frac{1}{2}$ and $y=x+\frac{1}{2}$ looks like but I am not understanding the problem as a whole What is a session 0? What is a "Session 0"?   When is it done? What does it contain? Is it recommended, if not mandatory? What is each person's role (DM/GM, players, etc.)? What topics are best discussed there?   Usually with my groups, we go directly to the meat of the game right after the character creation, but I see a lot of answers that basically say "you should have a session 0", but it's never explained what it is made of, so it's kind of an enigma for me. Sometimes I want to learn about a new programming related issue—topics such as DB ORM, search indexer, identity providers, logging, etc.  When I don't know anything about a subject, I ask for benchmarks or comparisons. I got some serious answers like links to tests, pros/cons, and Gartner's reviews. I found these very constructive and helpful. But then the question was blocked or deleted. Sometimes this happens even before I get an answer.  So where would it be more appropriate to ask questions about third party products and/or open source frameworks with which I am completely unfamiliar? I am running Wireshark on my linux machine and i have simple python web server running on localhost:8080  I am capturing only local port 8080. When i open browser on localhost:8080 wireshark captures huge amount of tcp communication (as page loads with all resources) but there`s no HTTP only TCP...   Why i cannot capture HTTP on custom port ? Actually I have installed the new Ubuntu 15.04 64bit, and when I'm trying to install Steam on it, there is a problem.

It only   looks more professional. If you want to place your tables where they   lie in your source code, do not use table at all! This is a very   common misunderstanding among newcomers.   LaTeX works with an intricate , but I often prefer immediate placement with the H placement specifier (enabled by the float package).  My understanding is that captions and table/figure numbering require the table/figure environments. Is this really so, or are there ways around that? What other reasons are there for using table/figure if we know that we don't want a particular object to float? derivative of cost function for Logistic Regression I am going over the lectures on Machine Learning at Coursera.   I am struggling with the following. How can the partial derivative of   $$J(\theta)=-\frac{1}{m}\sum_{i=1}^{m}y^{i}\log(h_\theta(x^{i}))+(1-y^{i})\log(1-h_\theta(x^{i}))$$  where $h_{\theta}(x)$ is defined as follows  $$h_{\theta}(x)=g(\theta^{T}x)$$ $$g(z)=\frac{1}{1+e^{-z}}$$  be $$ \frac{\partial}{\partial\theta_{j}}J(\theta) =\sum_{i=1}^{m}(h_\theta(x^{i})-y^i)x_j^i$$  In other words, how would we go about calculating the partial derivative with respect to $\theta$ of the cost function (the logs are natural logarithms):  $$J(\theta)=-\frac{1}{m}\sum_{i=1}^{m}y^{i}\log(h_\theta(x^{i}))+(1-y^{i})\log(1-h_\theta(x^{i}))$$ Getting shapefile of river from OpenStreetMap? I do not want to download the whole map of an area. I just want rivers and other waterbodies present in an area in shapefiles so that I can use them in QGIS. I tried geofabrik but it is giving whole map and that also of full country while i need data of a city. Right now I am trying JOSM. will update you when it will works. On , this is my tag blacklist:        Note well that I have them set to hidden, because I would prefer not to see questions on this topic. Bridge players, don't take offence &mdash; I don't have problem with the game itself. I don't understand the game's mechanics, though, so I find questions about it incomprehensible, and I'd rather stick to just seeing questions I can understand.  I still see [bridge] questions galore on the Android app though. Could it be updated to pay attention to whether I have certain tags ignored and set to be hidden? How can I do case insensitive string comparison in Python?  I would like to encapsulate comparison of a regular strings to a repository string using in a very simple and Pythonic way. I also would like to have ability to look up values in a dict hashed by strings using regular python strings.
