## Magento 1.9.4.2 known issues: compatibility with third-party checkout extensions

Anyone encountered a problem with a third party checkout extension like Amasty OPC or IWD OPC? I haven’t upgraded yet to Magento 1.9.4.2 because I read in the release notes that:

“Third-party checkout extensions and closed security cases will either not not work securely or will not work at all.”

## PHP Extensions “pdo_mysql” must be loaded

I’m installing Magento 1.x (2014 build), to Apache running PHP 5.6, MYSQL (latest).

I’m receiving the following error when attempting to complete the install PHP Extensions "pdo_mysql" must be loaded.

I’ve added (to the end of files):

extension=pdo_mysql.so

to both php.ini files: /etc/php/5.6/apache2/php.ini /etc/php/5.6/cli/php.ini

restart apache with sudo systemctl restart apache2

I’m still receiving the error:

PHP Extensions “pdo_mysql” must be loaded.

This is on the “Configuration” page of the Magento install.

I’ve added (to the end of files):

extension=pdo_mysql.so

to both php.ini files: /etc/php/5.6/apache2/php.ini /etc/php/5.6/cli/php.ini

restart apache with sudo systemctl restart apache2

I’m still receiving the error:

PHP Extensions “pdo_mysql” must be loaded.

## example of infinitely many intermediate field extensions

It is well known that $$\mathbb{F}_{p}(X,Y)/\mathbb{F}_{p}(X^{p},Y^{p})$$ is not generated as a field extension by one primitive element, hence it has to have infinitely many intermediate fields of degree $$p$$ (assume $$p$$ a prime number) over $$\mathbb{F}_{p}(X^{p},Y^{p})$$. I think that such fields are of the form $$\mathbb{F}_{p}(X^{p},Y^{p},f(X,Y))$$ for some $$f$$ polynomial in two variables over $$\mathbb{F}_{p}$$. How do we show that such fields are infinitely many or how to concretely exhibit otherwise infinitely many intermediate subfields?

## RFC 5280 compliant certificate with x509 extensions

First time posting here, be gentle.

Situation: I have a requirement, to link our printer/scanner to our Azure AD (so that it can lookup users etc.). I have enabled Azure AD Domain Services with LDAP enabled, and this works. I have tested the LDAP lookup by creating a certificate with the x509 extensions per the Azure documentation, installed the certificate for LDAP in AADDS and on my laptop, and can successfully search the domain. Without the certificate, it’s not working -so security wise it seems okay this far.

Upload a .PFX file containing the certificate to be used for secure LDAP access to this managed domain

The requirements for Azure AD DS LDAP certificate is here: https://docs.microsoft.com/en-us/azure/active-directory-domain-services/configure-ldaps:

Requirements for the secure LDAP certificate Acquire a valid certificate per the following guidelines, before you enable secure LDAP. You encounter failures if you try to enable secure LDAP for your managed domain with an invalid/incorrect certificate.      Trusted issuer - The certificate must be issued by an authority trusted by computers connecting to the managed domain using secure LDAP. This authority may be a public certification authority (CA) or an Enterprise CA trusted by these computers.     Lifetime - The certificate must be valid for at least the next 3-6 months. Secure LDAP access to your managed domain is disrupted when the certificate expires.     Subject name - The subject name on the certificate must be your managed domain. For instance, if your domain is named 'contoso100.com', the certificate's subject name must be 'contoso100.com'. Set the DNS name (subject alternate name) to a wildcard name for your managed domain.     Key usage - The certificate must be configured for the following uses - Digital signatures and key encipherment.     Certificate purpose - The certificate must be valid for SSL server authentication.

with an example on how to create it.

$lifetime=Get-Date New-SelfSignedCertificate -Subject contoso100.com  -NotAfter$  lifetime.AddDays(365) -KeyUsage DigitalSignature, KeyEncipherment    -Type SSLServerAuthentication -DnsName *.contoso100.com, contoso100.com

The printer is HP PageWide Pro 477dw MFP. I have been unable to find any real guides related to this printer and certificates/LDAP. The settings for the printer certificate says:

The file format must be PEM/Base64 encoded (.pem, .cer, .der).

Complication: The printer requires a RFC 5280 compliant certificate. I can create an RFC 5280 compliant certificate, but when I do it with the extensions required by ADDS LDAP, the printer does not validate it as RFC 5280 compliant. If I create a certificate without extensions, the printer can validate the certificate just fine, but then ADDS wont validate it.

Where do I go from here?

Kind regards

## Use Glide to load images from URL but without extensions

I could use Glide to load images from my local web server via the following code:

The problem is that with this method, I am limited to having access only to.jpg extensions, when sometimes the user may have chosen to upload a different type of image. Is there a way for Glide to handle loading an image from a URL, but without the extensions? Building an iterator would be fine, but may be unnecessary.

## Need information concerning multiple file extensions used by Krome

all. I have been attempting to work on a mod for Star Wars: The Force Unleashed, but of course, in order to do so, I first have to figure out where all the files are placed and how to get to them. So, I have a couple questions regarding the file structure of this specific game.

1. Does anyone know of a method to open .pkg files in the Star Wars: TFU ISO? I tried multiple bms scripts for quickbms, none of which worked.

2. Does anyone know what a .bpk file is or how to open it?

3. Does anyone know where the compiled code that makes up the actual game is located? This is mostly what I want to modify.

I’ve tried to do some research of the file hierarchy, files structures, and file types that Krome uses in their games, but for the most part, it seems to remain a mystery. Any help is greatly appreciated!

## On extensions of automorphism to crossed products

Let $$\sigma$$ $$\in$$ $$Aut(M)$$, Does $$\sigma$$ extend to automorphism to $$M\rtimes_{\alpha} G$$? If it is, what is the extension map?

## PowerShell to find accidental double file extensions

I have some users that occasionally accidentally double append a file extension to a file and have been trying to figure out how to script this in powershell.

E.G. The user names a file “document123.docx.docx” but they have visible file extensions disabled on their machine so they assume the file name is “document123.docx” How can I search for double appended file extensions so that this can be easily identified?

This only affects program code that expects the exact file to be named “document123.docx”and since it doesn’t exist it is unable to continue.

## SPFx extensions will work in SharePoint mobile app?

Platform: SharePoint mobile app

This question may sounds silly but need a definite answer. I have created multiple SPFx web parts and added them to pages. These are working fine, when I am trying to see those in SharePoint mobile app (android). But SPFx extensions are not having same behavior.

Solution background: I am trying to hide the command bar for the modern list due to some security reasons. This is working fine in browser but in SharePoint mobile app, I am still seeing options for the list items like delete, add etc.

My observations: I believe SPFx extension is not working because same elements are not presented in both interfaces.

Command bar in mobile app may be different so it is not working

Question: My observations are right or not? Is there any way that we can make it work in mobile app also for SPFx extensions?
