I am doing the following using iText.

1. I have a PDF
2. I add an image to the PDF
3. I save the modified PDF.

To add image in PDF I am using this method itext-add. This worked fine until I got a certain PDF. In this PDF, the adding-image-to-the-pdf method doesn't work. Moreover, it corrupts the PDF.

Points to note: I'm getting PDFs from a third party and these are contractual PDFs. So it is possible that they have added some restrictions.

And one fun fact, when I add an annotation on the same page where I want to add that image, that image starts coming!

I'm using iText 7.1.10

Write a script that does the following:

• get data from sheet
• modify column to flip names from [Last, First] to [First Last]
• modify 2 columns to abbreviate company names & statuses
• write resulting data to another spreadsheet without changing the format
• add timestamp for when data copied

I can get the data BUT it writes everything back as plain text. Thus instead of dates writing out as "yyyy-MM-dd", they write out as something like this:
Mon Oct 19 2020 01:00:00 GMT-0400 (Eastern Daylight Time)

Expectation: screenshot of dates as "yyyy-MM-dd"

Result: screenshot of dates as whatever this garble is

I have googled extensively and can't seem to find a solution. I believe my problem is with using toString() in the Array.map. I'm not sure how to restrict the map method to only the columns that need modifying. Right now it affects the whole array.
(I used the code from Google Apps Script for Multiple Find and Replace in Google Sheets to write this part)

Google has removed IE11 support in Angular 13. In the company that I work for, we have to keep IE11 support for the next few months due to contractual obligations.

As it's unclear what is the extent of removed "IE11 related code" from the framework, we are wondering if it's doable in practice to provide polyfills that would enable us to upgrade to Angular 13 and keep supporting IE11.

Have any of you researched this issue in-depth and successfully provided IE11 support after upgrading to Angular 13?

There are those [MTAThread] and [STAThread] attributes which control the apartment threading model for COM in .Net applications, and from my own (very limited) testing, CoInitializeEx() returns 1 (S_FALSE) if called from the main thread of a console C# application.

According to Microsoft documentation, S_FALSE means "The COM library is already initialized on this thread".

What I am wondering is whether there is actually a contractual guarantee in the framework itself that COM is going to be initialized on every .Net (Framework or Core application) thread?

If so, is it also guaranteed that all threads will be initialized with the same (STA or MTA) model?

I am asking this because for DirectShow applications it is crucial that COM is initialized on every thread, and I would like to avoid peppering the code with redundant calls to CoInitializeEx() and CoUnitialize() if those are already implicitly handled by the framework.

I came across a strange Excel book at work. When I retrieved a date value from any sheet in that Excel book, that value didn't match the date that it is supposed to represent.

However, the value 42978 doesn't represent 9/1/2021, but 8/31/2017. In fact, if you copied that cell to any cell in any sheet in another book, you would see 8/31/2017 in that cell. On the other hand, that value would always go 9/1/2021 in any cell in the original book. As seen, even though the macros have been disabled, I don't know how it can do that. I can't continue to work with that. Can someone please help me?

I would like to upload that Excel book, but probably can't contractually. And all macros in the book are password protected from editing and deletion, so I can't even see the contents of the macros.

Sorry.

Just implemented a custom cache store based on the official existing RocksDb one for a different backend store.

That leads me to a number of concerns/questions:

• Found out the hard way that PersistenceContextInitializerImpl is auto-generated and had added an import from Eclipse to resolve the issue. Now I have to leave it non-imported and showing as an error in Eclipse, is there a best practice way to handle this?
• Why is RocksDBDbStoreTest#testSegmentsRemovedAndAdded call when segmented is false, since this calls removeSegments that contractually should not be called if not segmented?
• Same class, why is buildConfig numSegments set or larger than 1 for non-segmented test cases?
• Any example of store implementing the NonBlockingStore transactional methods? Mostly wondering to make sure that all calls are from the same thread?
• Wanted to disable the compatibility test, since not supported in prior versions. Changed group to unstable or manual and would always still get called, which doesn't seem to match documentation. What is the right way to disable it from build time run?
• Are there any kind of performance/stress tests for persistence store that can be executed or adapted?

I am currently moving a Flask Application from Development to Production. The app itself is very tightly integrated with various Google Cloud Services - and is hosted on AppEngine. The Authentication is provided by Flask-Login and is required for every route (internal use only). In the app.yaml file i specify the following:
