Is it possible to make auto page numbering for Adobe Illustrator artboards?
Illustrator: how to change the artboard number?
See permissions for new files on a given directory I don't understand how my Linux machine is operating on new files.   I have an Amazon Linux AMI (RHEL based distro) and when I execute umask I get 0002, so I get whenever I create new stuff other users won't get write access.  But then I go to my home directory and I type:  $ mkdir myDir $ touch myDir/myFile $ ls -l | grep myDir   and I get  drwxrwxr-x 2 myself myself 4096 May 11 22:37 myDir   and for the folder:  $ ls -l myDir -rw-rw-r-- 1 myself myself 0 May 11 22:37 myFile   So apparently there's more going on there then my umask, since myFile permissions are more restrictive than just write protection.  Digging deeper, if I try:  $ sudo touch /var/run/myPidFile.pid $ ls -l /var/run/ | grep myPidFile.pid -rw-r--r-- 1 root    root       0 May 11 22:42 myPidFile.pid   So myPidFile.pid gets a much more restrictive default permission, under /var/run then myFile gets under my home folder.  We could blame the root umask but if I run umask under root I get 0022 which is indeed more restrictive then my user's 0002 umask but still doesn't explain how the execution bit permission isn't set.  So how can I understand a folder's default permission on Linux? Is it safe to check floating point values for equality to 0? I know you can't rely on equality between double or decimal type values normally, but I'm wondering if 0 is a special case.  While I can understand imprecisions between 0.00000000000001 and 0.00000000000002, 0 itself seems pretty hard to mess up since it's just nothing.  If you're imprecise on nothing, it's not nothing anymore.  But I don't know much about this topic so it's not for me to say.  double x = 0.0; return (x == 0.0) ? true : false;   Will that always return true? Let $ P(x)=x^8 - x^7 +x^2 -x +15 $, Descartes' Rule of Signs tells us that the polynomial has 4 positive real roots , but if we group the terms as $$ P(x)= x(x-1)(x^6+1) +15 $$ we find that $ P(x) $ does not have any positive roots.  Where did I err ? I keep reading in economics journals about a particular result used in random utility models. One version of the result is: if $\epsilon_i \sim_{iid}, $ Gumbel($\mu, 1), \forall i$, then:   $$E[\max_i(\delta_i + \epsilon_i)] = \mu + \gamma + \ln\left(\sum_i \exp\left\{\delta_i \right\} \right),  $$  where $\gamma \approx 0.52277$ is the Euler-Mascheroni constant.  I've checked that this makes sense using R, and it does.  The CDF for the Gumbel$(\mu, 1)$ distribution is:  $$G(\epsilon_i) = \exp(-\exp(-(\epsilon_i - \mu)))$$  I'm trying to find a proof of this and I've had no success.  I've tried to prove it myself but I can't get past a particular step.   Can anyone point me to a proof of this?  If not, maybe I can post my attempted proof up to where I get stuck. optimality of the Carnot cycle Factor analysis and regression PostgreSQL crash when connection failed Error log is:  016-02-21 21:22:34 GET DETAIL:  Connection matched pg_hba.conf line 83: "host    all             all             ::1/128                 md5" .... .... 2016-02-21 21:22:37 GET DETAIL:  Connection matched pg_hba.conf line 83: "host    all             all             ::1/128                 md5" 2016-02-21 21:22:37 GET FATAL:  password authentication failed for user "postgres" 2016-02-21 21:22:37 GET DETAIL:  Connection matched pg_hba.conf line 83: "host    all             all             ::1/128                 md5" 2016-02-21 21:22:37 GET LOG:  CreateProcess call failed: A blocking operation was interrupted by a call to WSACancelBlockingCall.

Fortunately, I can still login with this email address that I have lost access to.  I have been searching around here for a way to update it to the current one I use.  I have found many answers.  But they all give instructions to click on something not displayed or in one case, a page that prompts me to login via another email I no longer have the password for. I need current up to date instructions on how to change my email address or add another email-based login for this same user name that I am posting this with. How do I delete a Git branch locally and remotely? So this is the situation:   My brother received a PS4 on his birthday. He doesn't have a PS+ account, and I don't have a PS4, so I activated it as my primary PS4. Based on what I've read on the FAQ, any user can play my digital games and do online gaming since I activated the system as my primary PS4. A friend offered his account so we can play his digital games. He has a primary PS4 activated.   The question is, can we really play his games without any issues? For example, can we download GTAV from his account and play it using any account on our PS4? What do the words 'RELATED' and 'ESTABLISHED' individually signify in RELATED,ESTABLISHED state in iptables?

Determine which circuits are parallel and which are in series I need to find the Equivalent Resistance across A and B.

Restoring default toolbar layout in Blender 2.81 Extremely difficult logic question using conditional statement In this problem, we will only consider (real-valued) functions with domain $\mathbb{R}$. We define two new concepts. Let $f$, and $g$ be two functions.  We say $f$ is a rival of $g$ if   &emsp;&emsp;&emsp;&emsp; $\exists x\in \mathbb{R} \ \text{s.t.} \ \forall y\in \mathbb{R}, x \lt y \implies \lvert f(x)- g(x)\rvert\lt\lvert f(y)-g(y)\rvert$    We say $f$ is a frenemy of $g$ if  &emsp;&emsp;&emsp;&emsp; $\forall x\in\mathbb{R} \ \text{s.t.} \ \  x \lt y \ \ \text{AND} \ \ \lvert f(x)-g(x)\rvert \lt \lvert f(y)-g(y)\rvert$  Below are four claims. Which ones are true and which ones are false? If a claim is true prove it. If a claim is false, show it with a counterexample.  a) If $f$ and $g$ are any two functions and $f$ is a rival of $g$ then $f$ is a frenemy of $g$. b) If $f$ and $g$ are any two functions and $f$ is a frenemy of $g$ then $f$ is a rival of $g$. If $f$ and $g$ are any two functions and $f$ is a rival of $g$, then $g$ is a rival of $f$. Let $f$, $g$, and $h$ be any three functions. If $f$ is a frenemy of $g$ and $g$ is a frenemy of $h$ then $f$ is a frenemy of $h$  What are the four claims stating? Especially for c), the concept is not even present I am having a misunderstanding on how to solve them? Here is the dictionary I have  propertyList = {     "id":           "int",     "name":         "char(40)",      "team":         "int",     "realOwner":    "int",      "x":            "int",     "y":            "int",      "description":  "char(255)",      "port":         "bool",     "secret":       "bool",     "dead":         "bool",     "nomadic":      "bool",      "population":   "int",     "slaves":       "int", }   But when I print it out with "\n".join(myDict) I get this  name nomadic dead port realOwner secret slaves team y x population id description   I know that a dictionary is unordered but it comes out the same every time and I've no idea why. Add a custom curve mapping property for an add-on? Question The title says it all. I want to be able to make this in Blender's UI, and sample it at specific points :  Problem There is very insufficient documentation on this, and I can't find any examples for how to create a . I have worked with templates before, and , but it requires a curve mapping prop. Extra Info I found a few threads about this, and one gives me the impression that this cannot be done at all, but it is also very old.   This similar question has been asked here before, but it didn't even get a comment:  Is this even possible to access in python (as in only accessible in C)? How do I install different (upgrade or downgrade) PHP version in still supported Ubuntu release?
