Include some chat capabilities in iOS app Currently, the app notifies users when they're mentioned in chat. However, when we tap on the notification, we got redirected out of the app to Safari.   Is there a chance we can get some chat capabilities in the app, so that we don't have to login again in Safari to quickly reply to the messages?    App version: 0.1.19 09/19/2014 I've got a NI Traktor Audio 2 sound card I'd like to get working with Mixxx, but I don't seem to have any success so far. The card seems to be supported in Ubuntu out of the box, and it seems to work well with ALSA, but I cannot select it in Mixxx and I'm not sure whether is something I can do to make it see it (e.g. through).  So for testing purposes, on the command line I can execute aplay to check each channel:  aplay -D plughw:2,0,0 test.wav   and  aplay -D plughw:2,0,1 test.wav   That works well: I can hear the test sound on each channel (A and B)  The relevant output for this card using aplay -D is:  hw:CARD=TraktorAudio2,DEV=0      Traktor Audio 2, Traktor Audio 2      Direct hardware device without any conversions plughw:CARD=TraktorAudio2,DEV=0      Traktor Audio 2, Traktor Audio 2      Hardware device with all software conversions   From those 2 items on the output, plughw is the one that works, whereas hw doesn't.  The problem is that Mixxx only lets me select the hw card, which does not seem to work. I'd like to be able to select the plughw card, which is the one that's working.  I've tried suspending Pulse Audio as suggested by , but that did not seem to work. I also played around with an .asoundrc file similar to the one  (which was for an older model of this sound card), but also without success.  Any ideas on how to make Mixxx show the right card (and channel, while we are at it)?  Thanks! I was told that the following does not work:     Employees having children will be granted a day off.   However, this sounds better:     Having children, those employees will be granted a day off.   What is wrong with the first clause? Lightning Change Event Is there a way to catch the change event of a particular field/component? I saw on the AuraDocs that there is a valueChange event but trying to handle it makes the app throw an error on load. I was wondering if I could build some automatic field validation / search suggestions without relying on other js libraries. How can I connect the top loop to the down loop with faces Hey I want to connect the bottom loop with the top loop so that it forms a solid.  I have tried selecting multiple vertices and pressing F but that just creates a large face which I do not want. I have tried using grid fill bu that doesn't work either. The solution that seems to work is by selecting four vertices and pressing F and then selecting the next 4 and pressing F and on and on. That just takes too long. How do I create a new tag in the mobile iOS/ Android app? This operation is currently not supported.  When I tap the tags section, a search window opens; when I type something not existing and press Done, the tag section remains blank.  Please add such option to the apps. It is specially important in case of newly launched sites. How to extract a number from a string Im a newbie in Apex and im developing a page using Visualforce.  My string format is always like this "xx-xx-999999". In this format I need to get only the integer. For example the string is  "RO-W1-445567". I want to get only the integer 445567 in the string. Can someone willing to share a piece of apex code in my problem.  Your help is vey much appreciated.  Thanks in advance!  Ferdie Banu How can I compute the number of lists of the form $(a_1,\ldots,a_k)$, where $a_i \geq 0$ are integers and $\sum a_i \leq n$? What is the easiest way to derive the answer? In Ubuntu, applications can be opened from a terminal. But sometimes it isn't clear what the appropriate command is to do this.  So, having an application open, how can I get the command used to launch it, without having to search anywhere (just by looking at it)? Large text files load not working on android Is it possible to make abstract classes in Python? In the season 8 episode finale of Game of Thrones the highest important lords met with Grey Worm to free      Tyrion and Jon. While it was pretty clear why they wanted to free Jon it was unclear to me why they also asked for Tyrion.   To make things even more strange, they asked about his opinion of a potential solution which becomes the actual final one in the end      (choose king and nominate someone).   I thought they (besides Sansa and Bran) don't like him and wanted to judge him? Or am I missing something? Saleforce Too many future calls: 11 Is it possible to have test error lower than training error?  I have a classification problem with 2000 samples, 500 of which are positives, 1500 are negatives. I split my data into 70% training data, 30% test data.  Run random forest with 200 estimators and cv=10. I did this several times and compared the recall and precision score and notice the scores for my test set is significantly better. Is this possible? How to get remote host DNS address from a super-slim host (docker) without ping or bind-utils? On mu Ubuntu 12.04 setups my tmux clipboard copy and paste commands are setup as follows:  set -g prefix M-a unbind C-b bind C-c run "tmux save-buffer - | xclip -i -sel clipboard" bind C-v run "tmux set-buffer \"$(xclip -o -sel clipboard)\"; tmux paste-buffer"   This worked great for the longest time up until a month or so ago, when I suspect some configuration change or package change was made that broke the above. In GNOME terminal, pasting still works fine with both prefix+ctrl-v and ctrl-shift-v.   However the xclip copy command no longer works no matter what I do, and I have tried removing the custom prefix binding above, using -select instead of -sel, not using clipboard etc. This is pretty much a show stopper for a GVim user like me, since I don't even have the GNOME terminal workaround of ctrl-shift-c with tmux taking over the shell. I go into copy mode, select text with space+movement, and when I execute prefix+ctrl-c absolutely nothing happens. Before this broke, tmux would display a confirmation message in the notification section at the bottom.  Does anybody have suggestions as far as how one might debug this? This is a pretty big productivity hit. I can probably use the , but it'd be great to know just what happened to xclip. How do I find out which process is eating up my bandwidth? I think I'm being the victim of a bug here. Sometimes while I'm working (I still don't know why), my network traffic goes up to 200 KB/s and stays that way, even tough I'm not doing anything internet-related.   This sometimes happens to me with the CPU usage. When it does, I just run a top command to find out which process is responsible and then kill it. Problem is: I have no way of knowing which process is responsible for my high network usage. Both the resource monitor and the top command only tell me my total network usage, neither of them tells me process specific network info.  I've found questions here about monitoring total bandwidth usage, but, as I mentioned, that's not what I need. Is there another command I can use to find out which process is getting out of hand?  The command iftop gives results that disagree entirely with the information reported by System Monitor. While the latter claims there's high network traffic, the former claims there's barely 1 KB/s.  I've already tried killing all the obvious ones (Firefox, update-manager, Pidgin, etc) with no luck. So far, restarting the machine is the only way I found of getting rid of the issue. This is my attempt to prove that, if $a &gt; 0$, then $\frac{1}{a} &gt; 0$, using just field and order axioms.  $$a &gt; 0 \implies a \cdot \left(\frac{1}{a}\right)^2 &gt; 0 \cdot \left(\frac{1}{a}\right)^2 \implies a \cdot \left(\frac{1}{a}\right)^2 &gt; 0 \implies a \cdot \left(\left(\frac{1}{a}\right) \cdot \left(\frac{1}{a}\right)\right) &gt; 0$$  By associativity of multiplication:  $$\left(a \cdot \left(\frac{1}{a}\right)\right) \cdot \left(\frac{1}{a}\right) &gt; 0$$  We know that $a \cdot \left(\frac{1}{a}\right) = 1$, because one is the multiplication inverse of the other.   So we have:  $$1 \cdot \left(\frac{1}{a}\right) &gt; 0 \implies \frac{1}{a} &gt; 0 $$  Which is what we wanted to prove.   My question are:    In the field axioms, there's no axiom that says that $0$ times another number is $0$, but I have used this property. How would you translate it to field and order axioms? I have assumed that $\left(\frac{1}{a}\right)^2$ is positive, have you noticed? Note that I need a positive number in order not to change the $&gt;$ sign. But this is not present in the field or order axioms. How would you explain this? Return multiple values to a method caller Is "It is you who are mistaken!" correct?

Luke says something like "You are mistaken ..." which the Emperor answers with     No, it is you who are mistaken!   Why wouldn't he say     No, it is you who is mistaken!   instead?  I don't know what rules apply here but my stomach tells me the latter is (at least also) correct, although you would say "you are mistaken". It feels as if he should be referring to "you" in the third person.  Could you please shed some light? Are both correct or – if not – which one is correct? And why?
