QUESTION
I am trying to format the output of my command for usage on another machine. I use the trim() function but still PowerShell insists on making the strings equal length.
I think it has to do with me setting the size of the string but I had to do this to avoid the paths being truncated. How can I circumvent this behavior?
This is my command:

QUESTION
I am using Delphi 11 Alexandria and am building an FMX project for release on Windows, iOS, and Android.
I am building a manual language translation system, to this end I have generated a mapping document that maps language text to components mapped using the component name.
My customer has insisted that no auto translation technology should be used.
My code works fine for everything accept TComboBox
and TListItem
?
When I set the text value for the TListItem
on startup, it works. For instance, the design time values are in English, and if the save state determines the last used language was Deutschland then this function successfully changes the drop down text and header text of the TComboBox
(very odd).
However, when I change the language after startup to change all the text, it does not change the drop down text, but does change the header text value.
I.e. I initially load the text in English, the save state loads in English, and then I change to Deutschland.
When I change to Deutschland, the header text in the ComboBox says "Bereich" but the drop down value says "Area". This is true for all of the drop down values, only the header text changes and not the drop down values?
Please note: I have added the if
statement already if cmp is TListBoxItem then
for an easy place to position any additional code to make it work.
ANSWER
Answered 2022-Mar-21 at 15:41This is indeed a bug not in TListBoxItem
but in TComboBox
component. It has an optimization that prevents the list of items from being recreated every time the drop down is shown, except when an item is added or removed or the whole list is replaced through the Items
property. Seems that simply changing the text of items doesn't trigger such drop down recreation.
A workaround is to disable this optimization by copying the source file FMX.ListBox.pas
to your project folder and commenting out the FItemsChanged
check at the TCustomComboBox.InitPicker
procedure:

QUESTION
For various reasons I want to be able to use a proxied data table and replaceData while client side processing is being used i.e. DT::renderDataTable(..., server = FALSE)
.
I have a shiny application/dashboard that communicates to a database and presents information to a user. The user is able to fill out a form in the application which will be added to the database and then the shiny app updates the data by making a query to the database to fetch the new information.
The application is currently being deployed via kubernetes using a LoadBalancer
with the intention to use multiple replicas to scale up the application as needed. The application is not being run through shinyproxy.
Currently, when the application is being run by a single replica (process) the application will behave perfectly fine and is able to use server=TRUE
. However when I increase the number of processes/replicas to run, the data is not able to be presented to users unless server=FALSE
is specified in renderDataTable
. For a currently unknown reason but I suspect it might be due to the sessions not being sticky to IPs
While the code is able to function fine when server = TRUE
if I want to allow multiple users to application they all cannot share a single process as the application will become very slow once multiple connections are made. As a result I likely need to use server=FALSE
so each user is able to see the data at the cost of a very important functional detail (replaceData
stops working). The product owner of the application is insistent that this behaviour remains intact as the data present is often large and requires some column sorting and paging to find a piece of information you want to look at. And when submitting a form, if I do not use replaceData
and reconstruct the table from scratch the users previous table state is lost.
So while I could tear down the datatable and regenerate it within an observeEvent

QUESTION
I'm struggling to expose a service in an AWS cluster to outside and access it via a browser. Since my previous question haven't drawn any answers, I decided to simplify the issue in several aspects.
First, I've created a deployment which should work without any configuration. Based on this article, I did
kubectl create namespace tests
created file
...probe-service.yaml
based onpaulbouwer/hello-kubernetes:1.8
and deployed itkubectl create -f probe-service.yaml -n tests

Answered 2021-Nov-16 at 13:46Well, I haven't figured this out for ArgoCD yet (edit: figured, but the solution is ArgoCD-specific), but for this test service it seems that path resolving is the source of the issue. It may be not the only source (to be retested on test2 subdomain), but when I created a new subdomain in the hosted zone (test3, not used anywhere before) and pointed it via A
entry to the load balancer (as "alias" in AWS console), and then added to the ingress a new rule with /
path, like this:

QUESTION
Starting from C++17, it is possible to define a constexpr
function that will return a pointer on its local variable. The caller will so get a pointer on an object after its end of life.
Clearly such pointers cannot be dereferenced to avoid undefined behavior. But is it legal to compare them on equality?
Consider an example:
...ANSWER
Answered 2021-Oct-03 at 07:06This is, oddly, implementation-defined per [basic.stc]/4: the pointers returned by f
are invalid, so comparing them might do something bad. Of course, it’s not really clear what the space of possibilities includes here: a footnote mentions a runtime fault, which is usually lumped with undefined behavior, but during constant evaluation one would expect that to reliably fail the evaluation (which would be reported as “static_assert
expression not constant”). Supposedly, implementations are required to document their choice here, but I doubt any of them meaningfully address this particular situation.

QUESTION
Provider has this sample JAVA code to decrypt RSA using public key.
...ANSWER
Answered 2021-Sep-06 at 07:34From the Java code the padding is not clear, because only the algorithm is specified, but not the padding. In this case the padding is provider dependent, e.g. PKCS#1 v1.5 for the SunJCE provider.
Assuming PKCS#1 v1.5, the combinations Cipher.ENCRYPT_MODE
/private key and Cipher.DECRYPT_MODE
/public key apply RSASSA-PKCS1-v1_5 as padding. This is functionally identical to signing/verifying with NonewithRSA
(except that verifying with NonewithRSA
additionally checks the equality of the data compared to decryption with the public key).
NonewithRSA
means that the data is not hashed and no digest ID is prepended. This algorithm is actually intended to sign already hashed data (after the digest ID has been prepended). It is in no way meant to sign unhashed data, i.e. the Java code misuses this algorithm.
Since the message size is limited with RSA (key size minus the space required by padding), only appropriately short messages can be signed. Unhashed data whose size exceeds the allowed size therefore forces multiple signatures. This is the reason for the multiple decryption in the Java code.
The use of hashed data is not only useful for practical reasons (signing long messages), but also necessary for security reasons, s. e.g. here and here.
To implement the functionality of the Java code in Go, a low-level implementation is required for signing/verifying in Go as in the Java code.
Another possibility would be to implement the decryption (m = c^e) and remove the padding yourself, which for RSASSA-PKCS1-v1_5 simply consists of a sequence of 0xFF values framed by 0x0001 on the left and 0x00 on the right.
In the following, I consider the second approach. The Go code below does the following:
- Import the public key
- Base64 decode the ciphertext
- Split the ciphertext into the individual signature chunks (here 3 chunks containing the same data: The quick brown fox jumps over the lazy dog)
- Decrypt each signature chunk (m = c ^ e)
- Concatenate the decrypted signature chunks
