I don't know really how to ask this as a question because I'm not sure what is going on: in my Google Chrome browser the search bar's text is upside down when I try to type in it or click on it, everything else on the page is the proper way and when I click off the search bar the text goes back to normal. Is there something that I may have done to have this happen? It just started today and it is really really annoying. The only inference I have seen about this happening to someone else was on here:  and although several people claimed to have a similar problem that started occuring this week no one has been able to solve it
Google Chrome is my favorite browser, and I can't imagine going on without it. Suddenly (without closing and re-opening) the browser; chrome has been reading characters upside down, very weird:    Chrome version:    I tried restarting my browser and my MAC (running OS X Yosemite 10.10), but the error keeps on coming.
I need to print an image at a certain size. What dimensions and resolution should I use? Integrity constraints in a relational database - should we overlook them? I’m in a permanent discussion with the developers of the company where I work because they say it is better to get rid of relationship enforcement (via FOREIGN KEY constraint definitions) in a relational database in order to speed up large queries and to gain better performance. The platform under consideration is MySQL 5.x, and no FOREIGN KEY has been set up, even some PRIMARY KEY constraints of the relevant tables are missing which, at least for me, is not reasonable. Maybe they’re right and I’m wrong, but I don’t have enough arguments to discuss about this situation. This has been the preferred approach for three years now. I’m new in this company (only one month) but, as the product “works”, there is hesitation to enhance the database; nevertheles, the first thing I noticed is one page taking 1 minute to load (yes, 60 seconds!). One of the claims behind the current state of affairs is that a “denormalized” database is faster than a normalized one, but I don’t believe that’s true. Most of the relevant queries include JOIN operations, which makes them run very, very, very slow with large amounts of data (the database contains millions of rows). Commonly, the handling of “CRUD” operations is implemented at the application program code level; for example, in order to DELETE some data FROM, let’s say, TableA:  it is necessary to first check on the fly if there is some relationship between the rows of TableA and TableB, in case that said relationship is “detected”, then the app program code won’t allow to DELETE the pertinent row(s), but if for some reason the app program code fails, then the DELETE operation will “succeed”, no matter if there is any relationship regarding the involved rows and tables.  Question Could you help me to elaborate a good, accurate and solid answer to enrich the debate?  Note: Maybe something like this has been asked (and answered) before, but I couldn’t find anything by means of Google. found a 1994 uncashed profit sharing retirement plan check Are these adjectives interchangeable?  I always hear: 'An Arab man.' but never 'An Arabic man.' and I always hear 'Arabic coffee' but never hear 'Arab coffee.' How do I perform a Perl substitution on a string while keeping the original? How can you use optional parameters in C#? Note: This question was asked at a time when C# did not yet support optional parameters (i.e. before C# 4).  We're building a web API that's programmatically generated from a C# class. The class has method GetFooBar(int a, int b) and the API has a method GetFooBar taking query params like &amp;a=foo &amp;b=bar.   The classes needs to support optional parameters, which isn't supported in C# the language. What's the best approach?

Microsoft Edge missing in Start menu and pins How do I get my device detected by ADB on Linux? I just got my shiny new Wileyfox Swift – and before putting it to use I want to oem unlock and root it (as I usually do with new devices ;) Trouble is, though  is enabled on the device, and a corresponding line in /etc/udev/rules.d/51-android.rules exists, the device is not seen by adb devices.  I know there are several answers scattered around this site, but they are either hard to find, just cover a specific device, or don't cover all steps I finally needed. So I take this as a chance for a canonical, device-independent question and give it a detailed answer below:  How can I get my Android device seen and used by adb on Linux? Recovering a password for a Word 2007 document Forgive me for the unclear title. Some time ago, my HTC M8, which is rooted and runs on a  showed something weird. Firstly, in the Google Maps App a mysterious blue dot appeared, that captures the screen completely and makes it impossible to quit or use the application. It looks like this (I could make a screenshot)     When this happens in Maps, the only thing I can do is a hard restart with Power+Volume Up.  Since I have seen this occasionally in the camera app as well, I suspect it is not a bug of Maps itself. I know that the Venom ROM is not standard but maybe this is connected to some setting and anyone has seen this. Btw, the Venom ran smoothly for almost 3 years now.  Question: Has someone a clue what this could be and how I can get rid of it? Proving that $x_n\to L$ implies $|x_n|\to |L|$, and what about the converse? Problem 3. Show that for a sequence $(x_n)$ the following are true:   (i) $\lim x_n=0$ if and only if $\lim |x_n|=0$.   (ii) $\lim x_n=L$ implies $\lim |x_n|=|L|$. Is the converse true? Prove or give a counterexample.    (i) is already done, easy.  I'm halfway done with (ii), I split it into three cases:  $L = 0$, $L &gt; 0$ and $L &lt; 0$.  For $L = 0$ I just refer to part (i).  For $L &gt; 0$, we know that $|x_n - L| &lt; \epsilon$   if lim $|x_n|$ = $|L|$, then we must have  $||x_n| -|L|| &lt; \epsilon$  but by the reverse triangle equality, $||x_n| - |L|| &lt; |x_n - L|$ so clearly $||x_n|-|L|| &lt; \epsilon$, thus  lim $x_n = L$ $\implies$ lim $|x_n| = |L|$ for $L &gt; 0$  for some reason I'm confused as to part three, $L&lt;0$. I'm having trouble seeing the difference between $L&gt;0$ and $L&lt;0$, and i'm starting to think that splitting it up like that isn't necessary at all. Subject/Complement Agreement. How to describe problem with "The thing is the objects." In my , I provided the following, problematic,  wording (especially bold italic), and I need help to better understand this issue so I can fix my answer:1          The thing is the books. (Reduced form of Sentence 2.a)         Fundamentally, Sentence 2.a (the so-called "correct" answer), is grammatically defective. Recall there is another grammatical rule: the subject and subject's complement should match in number.    A clarification is needed here. I am not suggesting here, in this EL&amp;U question, that there is any such singular grammatical rule as indicated in the quote above.  The quote continues as follows:     The reduced sentence makes the disagreement between the subject's and complement's plurality obvious. What is one to do? Language is linear and we know "The thing is X" is better than "The thing are X", so we go with the former, which is the subject-verb agreement rule. But what is "the books" then? It must be thought of as a collective noun, even if it doesn't look or feel like one. Forcing something to be a collective noun is related to the idea of notional agreement.   Others noted that grammatically defective is too strongly worded.  There is no such "grammatical rule" for subject/complement agreement.  Please help me understand/improve upon my line of thought here.  I'm stating that Sentence 2.1 presents a fundamental "conflict" or "error" (however one might define error) at some level (morphological, syntax, grammatical, semantic):     The thing is the books.  (Or, "The thing is the objects.")   Based on the "obvious" morphosyntactic plurality conflict, the above sentence feels so wrong that I think many native speakers would think it "simply" grammatically incorrect. However, @F.E. gives counter examples:     And here are some more grammatical examples, where the number of subject and predicative complement don't agree: "They were a problem to us all", "That so-called work of art is simply four pieces of driftwood glued together" (CGEL, page 254-5). As CGEL says: "What is required is semantic compatibility, not syntactic agreement . . .". There are more examples on page 512: "The only thing we need now is some new curtains", "The major asset of the team is its world-class opening bowlers", "Our neighbors are a nuisance", "This gadget is five different tools in one".   I think all the examples given above can be explained as notional agreement.    Question 1: If we explain this phenomena in terms of notional vs syntactic agreement, where does "grammatically correct/incorrect" fit in?  Question 2: Can a simple sentence such as "The thing is the objects." be grammatically incorrect while more complex sentences such as "The thing is four pieces of driftwood glued together." be grammatically correct?  (The answer, in my mind, must be no; this is my conundrum.)  Question 3: Would it be better to say that Sentence 2.a has a low level of (linguistic) ?   Question 4: How about a low level of  and that it's semantically difficult to be (linguistically) ?    Question 5: Do we simply draw a hard line and say "The thing is the objects." is 100% grammatically correct?  I didn't particularly like this option based on intuitive notions of "grammatically correct".    1. Please help me and be kind; I'm trying to improve my understanding. I'm looking for cool, objective advice on how to look at this.  I numbered my questions so they can be easily referenced, if desired.  My preference is the final answer would sufficiently answer all the questions, but of course that can be done explicitly or implicitly. How can I start Hoard of the Dragon Queen with 4th level characters? I'm pretty new to DM'ing and was just wondering if there would be a way to start the hoard of the dragon queen adventure with a group of 4th level characters?  There don't really seem to be any modules for that level range yet.  We just finished a short module that took our party to level 4, but id really like to play through this adventure because it seems awesome. Also I couldn't really find any other ones that start around that level so rather than re-roll characters we'll just start a little of the way in. When trying to SSH into a particular Mac machine it gives me the following error :  ssh_exchange_identification: Connection closed by remote host   I have done some google searches on the issue but I haven't seem to find a definite answer. I did notice that on the machine that I am trying to SSH into, it does not have the ~/.ssh file even on there so I went ahead and created it and gave it correct permissions but that didn't help. Here is the verbose of when attempting to SSH into it:  penSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: Connecting to &lt;ComputerName&gt; [xxx.xxx.xxx.xxx] port 22. debug1: Connection established. debug1: identity file /Users/&lt;UserName&gt;/.ssh/id_rsa type 1 debug1: identity file /Users/&lt;UserName&gt;/.ssh/id_rsa-cert type -1 debug1: identity file /Users/&lt;UserName&gt;/.ssh/id_dsa type -1 debug1: identity file /Users/&lt;UserName&gt;/.ssh/id_dsa-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.2 ssh_exchange_identification: Connection closed by remote host   Any ideas on how to get SSH working? How would I go about evaluating this integral? $$\int_0^{\infty}\frac{\ln(x^2+1)}{x^2+1}dx.$$ What I've tried so far: I tried a semicircular integral in the positive imaginary part of the complex plane, excluding the negative real axis, but had trouble calculating the residue at $z=i$ (perhaps there is a way of doing this that I don't know of). After that didn't work, I tried a rectangular box integral from $\epsilon$ to $R$, from $R$ to $R+i/2$, from $R+i/2$ to $-S+i/2$, from $-S+i/2$ to $-S+i\epsilon$, from $-S+i\epsilon$ to $-\epsilon+i\epsilon$ and finally a semicircle around the origin, radius $\epsilon$.   Any help would be appreciated. Why wouldn't the `which` command work for `cd`? I can't find the executable for `cd` either! I tried which cd and it didn't give a path but instead returned the exit code 1 (checked with echo $?). The coreutil cd itself is working, so the executable should be there, right? I also ran a find for cd, but there was no executable file shown. How is it implemented then?  Update:  I don't know if I should ask this in another post but since I think it is good here, I'm expanding (?) the post... So the answer was actually quite simple, there's no executable for that — because it's a builtin — But I've found some builtins (bash shell in Fedora) have the executable files! So builtin -> no executable isn't right I suppose? Maybe an answer explaining what builtins actually are (builtin commands?), which actually is the matter here, rather than focusing more on cd... Some good links posted previously indicate that builtins are not programs... so what are they? How do they work? Are they just functions or threads of the shell? How do I increase the render distance? How do Natures work? In at least some Pokemon games there are modifiers called "Natures" which affect pokemon stats. What do they do and how do it work? Also, what specific games possess it? Scenario  I created a journey with a Contact Data entry event that is triggered via the API. A subscriber should be able to be injected multiple times and the values in the data extension are updated while the subscriber is in the journey. The updated values should determine the path the subscriber follows.  Setup  As changed data needs to be evaluated and the contactkey cannot be used as primary key, I added a random id as primary key and created an attribute group for the data extension in Data Designer. The data extension is linked to the contact's contactkey using a one-to-many relationship as a contact should be able to enter the journey multiple times.  In the journey I'm using a decision split that is configured to use contact data from the created attribute group and has two branches (as it checks a boolean value).  Problem  For multiple entries the decision split doesn't evaluate correctly and always leads to same branch (value equals false). I suppose the problem is that journey builder doesn't use the primary key to identify the correct row in the data extension. Is there any way to make sure the row is matched using this id and not the contactkey as this leads to some strange behaviour as described here:
