QUESTION
The openzeppelin minimal proxy contract here has this function predictDeterministicAddress() that hashes values like the sender's address, a salt... to generate a contract address that the create2 function will also generate, when its passed the same values as dictated in this EIP.
This EIP states that an arbitrary value 0xff when hashed with a salt, senders address and the contract bytecode will always generate the same address.
Im trying to implement the predictDeterministicAddress() function on TRON blockchain but the TRON docs specify a different arbitrary value, 0x41 for implementing this same feature.
I tried to just replace the values but i can't see where the openzeppelin team used the value 0xff in their function.
Below is the openzeppelin hashing function:

QUESTION
I need to retrieve MAX ResponsibleEndDate per Client. In case there is NULL, treat it as MAX date.
...ANSWER
Answered 2022-Feb-16 at 21:29Aggregate functions, in T-SQL, ignore NULL
values and NULL
is also treated as having the lowest value, not the highest.
As such you'll need to use a couple of functions to replace the NULL
with an arbitrarily high value, and then NULL
it again:
QUESTION
I'm building a report that will catch all gaps and overlaps in the Responsible Start and End dates.
Idea is to have a column (Status), that will have 5 outputs (I understand, that there is a possibility of multiple scenarios for a record, but I need them to be assigned in the below order:
- No Responsible - when no associated Responsible at all (ResponsibleId or ResponsibleName is NULL)
- No Current Responsible - when across all the records associated with the Client, ResponsibleEndDate is not NULL (means current).
- Overlap - when ResponsibleEndDate of the previous Responsible overlaps with ResponsibleStartDate of the following Responsible person.
- Gap - when a gap between ResponsibleEndDate of the previous Responsible and ResponsibleStartDate of the following Responsible person.
- Valid - when 1 day difference between ResponsibleEndDate of the previous responsible and ResponsibleStartDate of the following Responsible person.

QUESTION
If I want to not use any text editor and put all the commit message including subject and body lines into the useful one-line command:
$ git commit -m 'message including subject and body lines'
, I need to insert first body-line two lines after subject and the next lines just at the next new line.
For example:
feat: Derezz the master control program
- MCP turned out to be evil and had become intent on world domination.
- This commit throws Tron's disc into MCP.
So I tried to use "\n" but didn't solve the problem!
...ANSWER
Answered 2021-Dec-19 at 14:00If you're working in Bash (on Linux or in Git Bash on Windows), then you can use the $'...'
syntax from Bash, which lets you use \n
and other escape sequences:
$ git commit -m $'message subject\n\nmessage body'
will create a commit with message
QUESTION
I have a list of vehicle models and would like to display the associated types. As a selector I have written the types in a data-field. Now I want to hide with the class d-none all list items that do not match the selection.
This works with my current code. The problem is that I also get "Example Type 3" displayed in this example. But I only want to have "Example Type 2".
How can I make it so that only the 2nd element is displayed here but I can still search for "E-Tron S" or "E-Tron GT"?
My javascript so far:
...ANSWER
Answered 2021-Nov-17 at 19:12There is no exact text matching or reg exp in the selector, so you need to do the filtering without using the contains selector.

QUESTION
Does it cost anything to call a Smart Contract on Tron that returns data from the contract but does NOT change any data?
...ANSWER
Answered 2021-Jun-09 at 12:18It depends on how you call it.
The eth_call JSON-RPC method is free.
The eth_sendTransaction method creates a transaction and consumes gas in the form of native currency (in case of the Tron network, that's TRX).
Some wallet apps only support the transaction mode and do not support calls. Some JSON-RPC wrapper libraries such as web3js allow you to chose between the call (using the library .call()
method) and the transaction (using the library .send()
method).
Note: Even though the methods are prepended eth_
, they are used on the Tron network as well.
