Bypass the VPN restriction in another application

I want to know if it is possible to deceive this application "Diitalk" thinking that I am in the United States or preventing it from knowing that my VPN is working because if I have not d & rsquo; US-based IP address, it will not allow me to use the US-based number. .enter the description of the image here

Can this be done on the Android device itself without having to use a VPN router or any other device?

Restriction of Ext sheaves on closed sub-schemas

Let $ f: X rightarrow C $ to be a morphism, where $ C $ is a smooth curve. For $ in C $ let $ i_t: X_t = f ^ {- 1} (t) rightarrow X $ either the inclusion of the fiber of $ f $ more than $ t $and let $ mathcal {F} $ a wreath $ X $ it's flat $ C $.

Is there an isomorphism $ i_t ^ {*} mathcal {E} xt ^ 1 ( mathcal {F}, mathcal {O} _X) cong mathcal {E} xt ^ 1 (i_t ^ {*} mathcal {F}, mathcal {O} _ {X_t}) $ ?

8 – Ignore the restriction of registration of the site on the acceptance of an invitation

We have a custom module that uses the invitation module to send invitations to non-users. Our site is set to allow only registration by the administrator in order to avoid spam. When guests accept the invitation, they can not register because it is not allowed by the site. Is there a way around the registration restriction when guests are trying to register?

We're looking at duplicating the registration form on another route and then routing guests to register at the default route location.

Any other suggestions to handle this situation?

php – How to determine where an open_basedir restriction comes from

We are trying to upgrade to Mediawiki 1.30 with the help of the Mediawiki Publishing Archive. upgrade.php fails because components are missing from the release archive (for example, PHP unrecoverable error: error not captured: class "Wikimedia" Assert Assert & # 39; Not found).

If I analyze things correctly, it seems like we need to configure the web server as a development machine. We installed composer, symphony and its 33 dependencies according to the enhanced version of MediaWiki 26 alpha, Assert missing.

Attempt to run composition results in a open_basedir restriction in force ... error (see below). We are now trying to understand where the restriction comes from. According to How to set for a specific open_basedir directory, it is httpd.conf, php.ini or one .htaccess file.

The problem is that none of our configuration files have the restriction:

# find / etc -name php.ini -exec cat {} ; | grep open_basedir
; open_basedir, if set, limits all file operations to the defined directory
; open_basedir =
# find / opt / rh -name php.ini -exec cat {} ; | grep open_basedir
; open_basedir, if set, limits all file operations to the defined directory
; open_basedir =
# find / etc -name httpd.conf -exec cat {} ; | grep open_basedir
# find / opt / rh -name httpd.conf -exec cat {} ; | grep open_basedir
# find / var / www / html -name .htaccess -exec cat {} ; | grep open_basedir

I have two questions. First, is there a way to get a version tarball with everything needed to run the software?

Secondly, if a tar version archive is not available, how to determine where the configuration comes from?

# cd / var / www / html / wiki
# composer update

With a set of grammar rules, how do you know if they match without context or without restriction

With a set of grammar rules, how do you know if they fit without context or without restriction?

Just to understand (do not solve the one below),
for example:

begin {align}
S & rightarrow B / A, \
1B & rightarrow 111B, \
1A0 & rightarrow 00
end {align}

2010 – Scheduled Imposition of a Size and Type Restriction to a List Attachment

I'm using the code below to allow users to upload files as attachments to items in a SharePoint (2010) list.

How can I add type and size restrictions to the attachment, for example, if I want attachments to succeed only if the file is a .JPG file of less than 5 MB?

Void Page_Load Protected (Object Sender, EventArgs e)

penetration test – overflow of SqlDateTime .. Will this cause problems? Is it possible in this case to hack or circumvent the age restriction?

negative vote
We have a website with an age limit. If a user wants to sign up on our website, he must be 18 years old.

When I tried to register on our website, I just open the inspect element in the form field and add "0001" in the list of years. . After sending the form, an error is formed, such as (Near Button).

SqlDateTime overflow. Must be between
1/1/1753 00:00 and 31/12/9999 23:59:59.

Will this cause problems? If yes, what is it? Is this possible for any type of hacking or circumvention of the age limit in this case?

Aggressive geometry – In what way is the restriction of the pin being dimensioned to an irreducible component related to the compaction gum of the component?

$ DeclareMathOperator { Spec} DeclareMathOperator { hom} { mathcal {Hom}} DeclareMathOperator { ox} { mathcal {O} _X} $Let $ f: X to Y $ to be an appropriate morphism. In section 6.4. from Liu's book he introduces the $ r $-dualization sheaf $ omega_f $ for $ f $ satisfied
$$ f _ * hom _ { ox} ( mathcal {F}, omega_f) cong hom _ { mathcal {O} _Y} (R ^ rf_ * mathcal {F}, mathcal {O } _Y) $$
for all the almost coherent sheaves $ mathcal {F} $ sure $ X $.

In the particular case of $ f $ being finished, it proves that the 0-dualisation sheaf is given by $ f ^! mathcal {O} _Y = hom _ { mathcal {O} _Y} (f _ * mathcal {O} _X, mathcal {O} _Y) $ where this is considered a $ mathcal {O} _X $-module by multiplication in the argument.

Let $ X $ to be a good one-dimensional scheme on the field k $ and let $ Y = mathbb {P} _k ^ 1 $. Let $ omega_f $ denote the 0-dualizing sheaf for $ f $. Let $ Z $ denotes an irreducible component of $ X $. Let $ j: Z to X $ refers to the corresponding closed immersion. then $ f circ j $ is over again and we denote its sheath that doubles as $ omega_ {f circ j} $.

My question is: How is the restriction of $ omega_f $ at $ Z $ (via the withdrawal $ j ^ * $) related to the double-split pattern $ omega_ {f circ j} $ for morphism $ f circ j $?

Are they isomorphic? In general, I do not think so. But maybe in specific cases they are. Are there any canonical cards between them?

I am grateful for any kind of help.
