What are tag synonyms? How can tag synonyms be distinguished from "real" tags? How are new tag synonyms created? Who can create tag synonyms? How can I delete/reverse/undo bad tag synonyms? What are merged tags? Disabled mac os SIP but still can't delete default apps I'm using mac os 11.2.1 Big Sur. My question concerns using the Terminal utility to delete Apple default apps protected by SIP. I have disabled System Integrity Protection and confirmed that it is off by typing: csrutil  Terminal duly returns &quot;disabled&quot; to confirm that SIP is definitely off. I then attempted to delete various Apple default apps, as follows: sudo rm -rf FaceTime.app/  sudo rm -rf TV.app/  sudo rm -rf Mail.app/  But nothing seems to happen. The apps are still in my Applications folder and launch normally. If I try to delete them manually, I get a beep and the deletion is rejected just as if SIP were still enabled. Can someone suggest a better way to remove Mail? Blender Nodes in Editor doesn't show preview Image I have a small problem with my blender lately. I want to make some compositing with my compositing nodes but the problem is, blender won't show me the preview Image. I have a Screenshot for you guys.    The preview Image itself is enabled, but it just won't show.  Thanks for your help in advance!  -Marten Is it possible for test error to be lower than training error 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? This is a weird phenomenon.  Consider the following code:  \documentclass{article} \begin{document}   $$Z^* \frac{Z^*}{Z^*}$$ \end{document}   It produces the following picture:    The asterisks appear in various places in comparison to the Z. This looks particularly bad in the denominator. Any idea what's behind this? Can I dump my non-Retina Images for a iOS7 only app? Notify instantly when a currently viewed post is deleted At the moment SE shows us current voting results, a notification for new answers and comments, etc., instantly.

How do I set the proper exposure for nighttime moon photos? All my attempts to get a good shot of the full moon with my DSLR result in an overexposed circle on a black background.  I've tried using a tripod, remote shutter release, low ISO, and long exposure, but nothing has worked so far.  What combination of ISO and exposure time that will produce good results?   I particularly want to catch a full moon with the reddish effect when it is close to the horizon. I observed some naive examples. Spheres, for example, when we cut out one point, can be embedded into $\mathbb{R}^n$. And if we cut out a measure zero set of a projective space, it can be embedded into the Euclidean space of the same dimension. So I wonder if all manifolds can be embedded into a same dimensional Euclidean space when we cut out a measure zero set? Can anyone prove it or disprove it by giving me some counterexamples? Why is my camera limited to a shutter speed of 1/250th when the flash is up? Sometimes in bright backlight and with large aperture (f2.8) I want flash at high shutter speeds.  But when I pop the flash up on D7000 it caps the shutter speed to 1/250th, which overexposes the shots and makes everything look like a nuclear bomb just went off.  What's the logic behind the limiting of the shutter speed when using flash? Is there anything I can do to get flash  + faster shutter speeds? I have tried a little bit which as follows- Since $f(x_n)\in[0,1]$, $\{f(x_n)\}$ has a convergent subsequence say $y_n=f(x_{r_n})\ \forall n\in\Bbb{N}$ Let, $\lim y_n=l\implies \lim \frac{y_1+y_2+\cdots+y_n}{n}=l\implies \lim \frac{f(x_{r_1})+f(x_{r_2})+\cdots+f(x_{r_n})}{n}=l$ But I am getting no idea to proceed and prove the convergence of $\{x_n\}$. I have also tried to prove the sequence to be cauchy which goes- $x_{m+1}-x_{n+1}={\sum_{i=1}^m f(x_i)\over m}-{\sum_{i=1}^n f(x_i)\over n}\le {\sum_{i=1}^m f(x_i)\over n}-{\sum_{i=1}^n f(x_i)\over n}$ (since $m\ge n)$ $\implies |x_{m+1}-x_{n+1}|\le \frac{|f(x_m)|+|f(x_{m-1})+\cdots+|f(x_{n+1})|}{n}\le\frac{m-n}{n}$ (since $f([0,1])\subseteq [0,1])$ Now, what will I get if I tend $m,n\to\infty$? But I need to do something more in the 2nd case since I have nowhere used the continuity of $f$.  Can anybody give an idea to prove it? Thanks for assistance in advance. Replaced wrong car in garage in GTA Online I was asked to replace a car in order to put another car in my garage. However I thought I would be able to swap the car I wanted in and take out the other car that was already in there so I could bring it to my other garage. Can I get my car back? Writing ISO 19139 compliant XML metadata from spreadsheet? I am looking at a way to migrate the metadata from a spreadsheet into ISO 19139 compliant XML metadata documents for a collection of shapefiles. I can parse the data out of the spreadsheet into strings without issue however I am getting lost on how to take those strings and use them to populate the elements.   This example:  covers most of what I want to do, however I would need to generate the tree beforehand based on the ISO 19139 schema. PyXB seems to have schema bundles for OpenGIS but I would like some insight on how to connect everything. Ckeditor toolbar not entirely showing up I have just moved my site from local machine to production, the wysiwyg editor based on ckeditor no longer show the complete toolbar. I have a minimal list of element. Can someone help, am trying everything, edit profile, check if all files are uploaded, i don't see any problem ! In Greek, λογικοφανής is a word that describes a person who spits out seemingly logical statements. It often has a negative connotation as it is targeted towards people who tend to fool the public with supposedly beautifully-constructed thoughts that sound convincing in our ears but are not necessarily accurate. The first word that comes to mind is deceptive, but it is not quite what I look for. Any thoughts? Why is ++i considered an l-value, but i++ is not? A Monk threw three coloured darts, then spends one minute searching the battlefield, how many darts does the Monk recover? Very simply put:  I have a class that consists mostly of static public members, so I can group similar functions together that still have to be called from other classes/functions.  Anyway, I have defined two static unsigned char variables in my class public scope, when I try to modify these values in the same class' constructor, I am getting an "unresolved external symbol" error at compilation.  class test  { public:     static unsigned char X;     static unsigned char Y;      ...      test(); };  test::test()  {     X = 1;     Y = 2; }   I'm new to C++ so go easy on me. Why can't I do this? Why can't I buy the Windhelm house (Hjerim)? This question is the converse to:    In Overleaf LaTeX Editor, if you type some markup that the autocomplete does not recognise, it gets added to the autocomplete. 99% of the time this is great.  However, if you mistype something, such as \bodl instead of \bold, you will forever have \bodl come up as the first suggestion when inputting \bo...!   As the length of the document increases, and the number of typos goes up, the number of incorrect suggestions quickly starts to outweigh the benefit of the autocomplete, which is a real shame.  How can I remove these typos from the autocomplete?
