            Use serilog as logging provider in blazor webassembly client app
            Asked 2022-Mar-31 at 10:10

            I'd like to use serilog in a blazor webassembly net 6 app, both on client and server sides. In this article I found out how to relay log entries to server so that they are written in log files.

            In this approach however the Log static class is used to explicitly add log entries.

            I'd like to add serilog as logging provider so that exceptions and automatically generated information are logged, too.

            On server side I use

            I've been able to add Serilog to my client application logging providers by adding the Serilog.Extensions.Logging NuGet package.

            How to execute Powershell's "start-process -Verb RunAs" from inside a Batch where the elevated command inherits the Batch's environment?
            Asked 2022-Mar-17 at 22:55
            1. Problem

            I have a complicated batch file where some parts need to run with elevated/admin rights (e.g. interacting with Windows services) and I found a Powershell way to do that:



            Answered 2022-Mar-15 at 22:30

            Here's a proof of concept that uses the following approach:

            • Make the powershell call invoke another, aux. powershell instance as the elevated target process.

            • This allows the outer powershell instance to "bake" Set-Item statements that re-create the caller's environment variables (which the outer instance inherited, and which can therefore be enumerated with Get-ChilItem Env:) into the -command string passed to the aux. instance, followed by a re-invocation of the original batch file.

            Caveat: This solution blindly recreates all environment variables defined in the caller's process in the elevated process - consider pre-filtering, possibly by name patterns, such as by a shared prefix; e.g., to limit variable re-creation to those whose names start with foo, replace Get-ChildItem Env: with Get-ChildItem Env:foo* in the command below.



            Linking Patreon API with a Flutter application
            Asked 2022-Mar-04 at 02:13

            I am very new to using Flutter and have never properly used an API without help. I want to make my application free (without tons of ads) so I was hoping to create a Patreon to support it's upkeep. When looking for tutorial videos online or any examples of code to use for either Flutter or any other languages I know how to use, I came up empty handed. So I was posting this question here hoping that someone could help me link the Patreon API to Flutter. The documentation doesn't say it connects directly to Flutter, so you'll have to use another language to access the information (best bet is Javascript or Python on my opinion) and relay that too Flutter.

            I (and possibly other people) would need a button created for OAuth login through Patreon (that works on both iOS and Android). When the user goes through the login, it needs to grab which tier they are supporting, their username, and when their subscription will renew (monthly or yearly?). This then needs to be translated to Text widgets (displaying the tier and/or username) and a "visible:" property for Visibility widgets (displaying certain content based on the user's monthly subscription and making the same content invisible or put behind a newly visible lock page when their subscription ends/expires).

            Sorry I know this is a lot to anwser, but I'm not very experienced with APIs and Flutter. I will appreciate any anwser that helps because I really want to make my app without tons of advertisements and I'm hoping this question will help other Flutter developers with the same goal of supporting their development financial without tons of advertising effecting the user's experiences on the app.

            Patreon API OAuth Documentation

            Flutter JS (I think this may help connect with the Patreon API, but I'm not sure?)

            Examples of code and a step by step guide would be fantastic, but anything will help. Thank you again!

            What is best practice (and legal) for product listing image alt text for accessibility?
            Asked 2022-Feb-25 at 20:03

            I'm trying to determine what structure is best with regard to typical e-commerce product listing pages. I have reviewed WCAG and other sources and have not found a definitive solution as of yet. A typical product listing contains an image and a product name, both linked to the product details page. There are several patterns that come to mind...

            Single link with empty alt text

            My thought is that it is best to combine both of these into the same tag and then set alt="" on the image therefor the product name will describe the entire purpose of the link.

            Method 1 ...


            Answered 2022-Feb-25 at 19:14
            Which method(s) are best for users?

            Method 1 out of the options given is best.

            Which method(s), if any, would NOT satisfy WCAG Level AA and therefor not comply with laws in the US, EU, etc.

            None of them would fail WCAG as such.

            However as you have pointed out 2 and 3 result in duplication of effort for keyboard users and links to the same location having different names, which is not a fail under any success criterion but is highly recommended.

            Would the image in a Product Listing Page be classified as "decorative"?

            Yes in scenario 1 and 4.

            Expansion of the answers given

            All 4 of the examples given would "pass" WCAG. However they offer very different experiences.

            So the question is what things are we considering for accessibility?

            The first is Keyboard operability. Examples 2 and 3, as you pointed out result in duplication of focus stops for the same item. So we should avoid them.

            The second thing is link purpose. Yet again examples 2 and 3 are not great here as we have 2 links to the same place on the same page that have different accessible labels / text that assistive tech will use.

            So we can rule out options 2 and 3 for best practices.

            So what about options 1 and 4?

            Well as the items are located within a hyperlink we want the link text (the accessible name for those links) to be descriptive of the product page we are going to visit.

            As such option one would read: "link: Squeaky Fox Dog Toy" and the second link would read "link: (image) Red fox stuffed dog toy with white braided rope arms, Squeaky Fox Dog Toy"

            The second option results in duplication of information so is not as desirable as the first option.

            So we land on option 1.

            The only consideration you now have is whether that link text describes the product sufficiently. Now if you sold multiple dog toys (different product types) then you need text that describes them as such i.e. "plastic dog toys" and "fluffy dog toys".

            If you sell different coloured products and they all had their own page (so you don't have a colour picker on the end page, they are listed as separate items) then you would need to describe the colour there too. "Red fluffy dog toy", "blue fluffy dog toy".

            Essentially you need to provide enough information that each product link is easily identifiable as to where it leads (the purpose of the link itself).

            This is where judgement comes into play, provide enough information to describe the product generally in a unique way on the page, not so much information that browsing that page becomes problematic due to 100 products with 200 word link text.

            So in the example given the "balance" would be something like "Red fox stuffed dog toy", and then describe the appearance in far more detail on the product page, wither in the description or in the product image alt attributes.

            Option 5 - if you don't have text at all.

            It is worth noting that the last option for a product page is no text at all. Just an image inside a link. The following is also valid HTML and accessible as the alt text will be used as the link text (not if an image contains any text at all that should all appear in the alt attribute).

            Answered 2022-Feb-17 at 12:00

            That is odd. The sending source IP is definitely in your SPF, and the DMARC record includes aspf=r, so the header from address in a child domain is valid and matches. I'd also note that your DMARC has p=quarantine, but gmail is acting like it's reject. This is gmail though, so you can't expect it to behave well.

            I expect that the problem is that you don't have an SPF record set for, so make sure that exists and allows the same sources as It looks like you're not doing DKIM signatures either, meaning that both SPF and DKIM are failing, resulting in a DMARC failure. Try adding that DNS record, or redirecting/including server. to your root domain.



            Log4j vulnerability - Is Log4j 1.2.17 vulnerable (was unable to find any JNDI code in source)?
            Asked 2022-Feb-01 at 15:47

            With regard to the Log4j JNDI remote code execution vulnerability that has been identified CVE-2021-44228 - (also see references) - I wondered if Log4j-v1.2 is also impacted, but the closest I got from source code review is the JMS-Appender.

            The question is, while the posts on the Internet indicate that Log4j 1.2 is also vulnerable, I am not able to find the relevant source code for it.

            Am I missing something that others have identified?

            Log4j 1.2 appears to have a vulnerability in the socket-server class, but my understanding is that it needs to be enabled in the first place for it to be applicable and hence is not a passive threat unlike the JNDI-lookup vulnerability which the one identified appears to be.

            Is my understanding - that Log4j v1.2 - is not vulnerable to the jndi-remote-code execution bug correct?


            This blog post from Cloudflare also indicates the same point as from AKX....that it was introduced from Log4j 2!

            Update #1 - A fork of the (now-retired) apache-log4j-1.2.x with patch fixes for few vulnerabilities identified in the older library is now available (from the original log4j author). The site is As of 21-Jan-2022 version has been released. Vulnerabilities addressed to date include those pertaining to JMSAppender, SocketServer and Chainsaw vulnerabilities. Note that I am simply relaying this information. Have not verified the fixes from my end. Please refer the link for additional details.



            Answered 2022-Jan-01 at 18:43

            The JNDI feature was added into Log4j 2.0-beta9.

            Log4j 1.x thus does not have the vulnerable code.



            What to do with AWS Cognito's public key in ADFS
            Asked 2022-Jan-28 at 09:37

            I'm trying to configure AWS Cognito to work with ADFS as a SAML provider in a dotnet core 3.1 MVC application. I believe I have ADFS and Cognito correctly configured as I can log into the application using a user in ADFS. I am at a stage where I can login and logout, however when logging out ADFS throws the error:

            MSIS7054: The SAML logout did not complete properly.

            This does still log the user out of ADFS. I think I’ve narrowed it down to the SAML logout messages ADFS receives need to be signed. References: here, here and here

            Amazon describe how to do this from there end

            To set up the SAML IdP to add a signing certificate: To get the certificate containing the public key which will be used by the identity provider to verify the signed logout request, choose Show signing certificate under Active SAML Providers on the SAML dialog under Identity providers on the Federation console page.

            However, I’m not sure how I take their public key (which is just a string) and provided that to ADFS. The only thing I can seem to find is an encryption tab, that takes a certificate file (Is there some conversion thing I need to do?). I have tried this, which is putting the key inside a .cert file and adding to the relaying party encryption tab of ADFS, however this did not work.

            Any help would be appreciated.

            Thanks, Adam



            Answered 2022-Jan-28 at 09:37

            I eventually solved the issue by taking the key from AWS Cognito and putting it in a .crt file like this said, but instead adding it to the signature tab rather than the encryption tab in the relaying trust party's properties in ADFS.



            @ is for matmul/inner, what's for the outer product?
            Asked 2022-Jan-13 at 20:56

            In Python, the @ operator relays to the __matmul__ property of an element. This comes in handy when implementing a method that stays agnostic of the actual backend. For example



            Answered 2022-Jan-13 at 20:56

            The @ operator was added as PEP 465 for __matmul__. There is no such thing (and no dunder method) for the outer product.

            In fact, the outer product is a simple multiplication (*) once the first array got reshaped:

            Judging from the usage of the rename command in the second code, you seem to have the perl-based rename command available. (There are two different rename commands, one is perl-based, the other is not. Confusing.)
            Then you can rename the files removing the double quotes just with:



            How do I replace 0 with a random integer number in dataframe in python?
            Asked 2022-Jan-02 at 08:19

            Hi and happy new year :)

            I have a database in SQLite3 where ID is Primary Key, and if a new row with the same ID number is added, it replaces the row with new data. But the program that generates the CSV-file for this put in ID 0 if a Target is empty. The problem is if there are several rows with ID 0, there will only be one in the database because it replaces ID's if there are several. And that makes a problem in my app when I query for data from database because I have to have both targets, 1 and 2 from a relay with the same number. What I want to do is every ID with 0 has to be converted to a random integer number between 1000 and 2000, and that random number can't be generated twice.

            I have tried df.loc[df['ID'] == 0,'ID'] = df['ID'].apply(lambda x: np.random.normal(0,1)) df, but this only makes a random float and I can't use that.

            How do I solve this? Thanks in advance for your answers:)



            Answered 2022-Jan-02 at 08:19

            Creating a Series with values in the range of 1000-2000 and then calling its sample method gets what you want. Note that the sample method has a keyword argument replace which is False by default (which disallows sampling of the same row more than once).
