After creating an Apple ID in another location, I am forced to enter payment information in the iOS, Mac, and iTunes stores.  Even when trying to purchase a Free app, I am forced to enter payment information, and the None option is not present.  I am in the US.
Ever since adding an iTunes gift card to my account, I'm getting verification requests like crazy. I can't even download free apps. It takes me to my payment info and when I try to select none, I continually get a message under the payment info that says "you must verify your payment info to continue"  I don't want a credit card on file and would really like the none option to work. My ID shows I still have iTunes credit.

I need info for geodatabase and SDO_geometry (arcsde)  and yes there is a way. I use:  UPDATE layer1 a SET arctype = 'compound' WHERE has_compound_curves(a.shape) &lt;&gt; 0;   and then using ET Geotools to densify  layer by layer.  But there should be easier way of doing this straightforward in Oracle or ArcMap, and I just want to densify the features that have true arc. I don't want any unnecessary vertices on straight lines and so on.  How can I identify true arcs in ArcMap, and how can I densify them as fast and easy as possible?  Same for Oracle SQL. Advanced format partition alignment I cloned a non Advanced Format drive (W7 64bit) to a new hard drive (Seagate) that was AF, the software I used supposedly does not support 4k very well (Todo Backup Free 3.5).   Is there a Windows utility to check alignment? I know of the Western Digital tool but not sure if it works on Seagate brand drives. If the partitions are not aligned, Am I better to clean install W7 64bit or do the partition alignment procedure? If so, Why?   It seems to be running fine so far. From what I have read Seagate drives use  technology to help with misaligned partitions on the fly, might explain why it runs well for me, but would still like to have the partitions aligned properly.  EDIT: Here is the diskpart output for my disk partitions  DISKPART&gt; list partition    Partition ###  Type              Size     Offset   -------------  ----------------  -------  -------   Partition 1    Primary            188 MB    31 KB    Partition 2    Primary            698 GB   188 MB Next month I am traveling to country X, where I would need Y minutes of calls, Z text messages and most importantly Q megabytes of data. How can I find the cheapest/most reliable SIM card for my needs? Debugging with command-line parameters in Visual Studio I'm developing a C++ command-line application in Visual Studio and need to debug it with command-line arguments. At the moment I just run the generated EXE file with the arguments I need (like this program.exe -file.txt) , but this way I can't debug. Is there somewhere I can specify the arguments for debugging? On vs At with date and time This must be a simple question for a native speaker.  I know that we use "on" with dates: I'll see you on January 1st.  And we use "at" with times: I'll see you at 17:30.  But what preposition has to be used when we speak for date and time:  I'll see you on January 1st at 17:30. looks ok.  But what in this case: It happened on 2014-01-01 17:30.  Is "on" correct when we are specifying the date and the time?   The date-time comes as a ready text as 2014-01-01 17:30 and I cannot modify it. I can only put text before the date-time string or after it. Understand PAM and NSS In the last days I have set up some Linux system with LDAP authentication and everything works fine, but there's still something I can't really understand regarding NSS and PAM, also after a lot of research. Citing:  NSS allows administrators to specify a list of sources where authentication files, host names and other information will be stored and searched for  and  PAM is a set of libraries that provide a configurable authentication platform for applications and the underlying operating system  What I don't understand is how PAM and NSS work and interact together. In  the architecture is explained pretty well: I configure PAM to use pam_ldap for LDAP accounts and pam_unix for local accounts, then I configure nsswitch.conf to fetch information from local files and LDAP. If I have understood correctly LDAP is used twice: first by pam_ldap and then by NSS which is itself called from pam_unix. Is that right? Is LDAP really used twice? But why do I need to configure both NSS and PAM? My explanation is that PAM performs different tasks than NSS and it is used by other programs. But, then, it should be possible to use only NSS or only PAM, as I have read in . So I experimented a bit and I have first tried to delete LDAP from the nsswitch.conf (and the authentication stopped to work as if only pam_ldap is not enough to do the job). Then I re-enabled LDAP in NSS and I deleted it from the PAM configuration (this time everything worked fine, as if pam_ldap is useless and NSS is enough to authenticate a user). Is there anyone who can help me to clarify this? Many thanks in advance. UPDATE I've just tried something now. I removed again all the pam_ldap entries in all pam configuration fields and I have also removed shadow: ldap from nsswitch.conf. As now in all the system there are only the lines: passwd: ldap files and group: ldap files in nsswitch.conf. Well... the login with LDAP users works perfectly, those two lines (plus /etc/ldap.conf) are enough to configure LDAP auth. From my knowledge PAM in independent from NSS, but my tests showed it's not. So I ask myself is it possible to completely disable NSS and use only PAM? Say I create an object as follows: let myObject = {   &quot;ircEvent&quot;: &quot;PRIVMSG&quot;,   &quot;method&quot;: &quot;newURI&quot;,   &quot;regex&quot;: &quot;^http://.*&quot; };  How should I remove the property regex to end up with new myObject as follows? let myObject = {   &quot;ircEvent&quot;: &quot;PRIVMSG&quot;,   &quot;method&quot;: &quot;newURI&quot; }; What are the advantages of a custom ROM over rooted stock? How can I apply an effect when a player left-clicks/right-clicks with an item in hand? I made a map with annotations in QGIS 3.0.  This is how it looks like in the layout view:    If I print the map as PDF, one would expect to get the PDF to be WYSIWYG, right? However, it looks like this (it's about half the size):    Is there a way to influence the the scaling of the Annoations? I already tried to play with the Scale and Magnifier in the map view. I also tried to change the Scale in the map item.   The strange thing is, I believe it worked a few days ago. But today I installed QGIS 3.0 on a new PC and it showed the same behaviour...

Prove that $V \nsubseteqq H^1(\Omega)$  My problem is to prove 2. I need to find the cardinality of the set $S$ of all infinite subsets of $\mathbb{Q}$.   It's easy to prove $\operatorname{card} S=\mathfrak c$ if you first prove that the cardinality of the set of all finite subsets of $\mathbb{Q}$ is $\aleph_0$.   But is there some other proof for the statement without using the second one (about finite subsets)? Probably there is =) How to remove session entries from LightDM? I would like to see my review audit history Confession: I have been suspended a couple times from reviewing activities.  Partial Redemption: I have become better and better at passing audits.   I'd like to see my recent and distant history with audits.  Even better, I'd like to see my history with the various types of audits.    I'm not sure this has much value beyond self-reflection and self-analysis. I'd like to see if there are patterns to when I was more likely to fail (do I get sloppy after 10 or 20?), or if there are certain types of reviews at which I struggle more (e.g., suggested edit vs close question).  I suspect that if I reviewed my history and revisited audits I failed, I could create rules and rhythms for myself to become a better reviewer. Arch on WSL: libQt5Core.so.5 not found, despite being installed I was hit by some hardcore power-tripping forum mods on the Arch Linux forum, so here I am.  I'm trying to run GUI apps on WSL, such as dolphin or kate. However, none of them can find libQt5Core.so.5, despite it being installed in /usr/lib as you'd expect.

I just have to set the $DISPLAY variable. Not setting the var doesn't help, as you'd expect.  Any ideas? Thanks! Let $f$ be a continuous function. If $f$ is uniformly continuous then it maps cauhy sequence into cauchy sequence. Is the converse true? That is if $f$ maps cauchy into cauchy gives the uniform continuity of $f$. I think it's no. Can suggest a counter example I have a map of a city and a .csv-file containing 700 geographic coordinates pointing to locations within that city.  How can I plot these 700 locations on the map?
