QUESTION
In the documentation of LocalNodeFirstLoadBalancingPolicy, it's mentioned that -
Selects local node first and then nodes in local DC in random order. Never selects nodes from other DCs. For writes, if a statement has a routing key set, this LBP is token aware - it prefers the nodes which are replicas of the computed token to the other nodes.
However in my spark jobs logs I can find all the Nodes is cluster being added.
...ANSWER
Answered 2021-May-08 at 07:05You can ignore these messages. This is how the Cassandra works - drivers are discovering the full topology of the cluster on initialization, and then deciding to use only specific nodes from given datacenter.
For example, messages like New Cassandra host /x.x.x.54:9042 added
are coming from Java driver. And messages like Added host x.x.x.238 (DC2)
are coming from LocalNodeFirstLoadBalancingPolicy that must override the function in the interface. But then, load balancing policy doesn't use the nodes that aren't in the local data center, although always keeps a map of all nodes.
QUESTION
I am trying to use WebBrowser.Print() to print an html file which contain arabic character, the problem is that the arabic chatacter changed to strange chracter
Below are the html file code:
...ANSWER
Answered 2021-Mar-03 at 23:31Without a good Minimal, Reproducible Example and other debugging details, it's impossible to provide a complete solution.
That said, the output you show is clearly a problem with text encoding. Your HTML shows an encoding of windows-1252
, a character encoding that does not include any Arabic characters. So even though you've apparently entered Arabic characters in the HTML file, presumably using an editor that is treating the file as UTF8 where Arabic characters are supported, the bytes of the file will be rendered as if it's in the stated encoding of windows-1252
.
The bytes that are supposed to represent Arabic characters will then be interpreted according to the windows-1252
encoding, rather than the Arabic characters you expect. Because that's what you told the HTML renderer to do.
Most likely, if you would just provide the correct encoding name in the HTML, it would work. E.g.:

I am trying to convert some short python code into Rust. It has a main recursive function.
But I am trapped in the following error which occurs near bottom of the pasted code. Reading the answers for the same error number seems difficult to interpret for my case. Please give some hint to fix the error.

Answered 2021-Feb-20 at 13:59It looks you're cloning and then immediately passing a ref of the clone to parseExpr
. In that case have you considered transferring ownership of tok
to the method instead of passing a mutable ref, since you're cloning it anyway?

QUESTION
Is there a way to find out which node was contacted first during the initial setup by the driver? For example, is there a way to find the host 10.9.58.64 that was contacted?
...ANSWER
Answered 2021-Jan-30 at 16:29Right after the connection is established you can use the cluster.get_control_connection_host function to get information about host to which so-called control connection is established. It's used for administrative purposes, such as getting the updates on the status of the nodes in the cluster, etc. There is more information about control connection in the documentation of Java driver.
QUESTION
So this Script changes the currency and symbol if I selected the currency from a select tag in html, but the problem is that it changes the currency and symbol only for the first card but the others not. Is there a way to change them all at the same time without doing a script for every card? the select works as follows: If I chose LBP and the currency was USD then the number would be multiplied by 8500 and if chose USD with the currency being in LBP then it would be divided by 8500, while if I chose the same currency that is chosen then nothing happens.

Answered 2020-Dec-24 at 14:08First of all, it's a very bad idea to duplicate an ID...
Document.getElementById() return only one DOM element
, so my advice is that you use classes, and then, use Document.getElementsByClassName() or:
QUESTION
so my code is about when I select the currency the price and symbol must change; if I chose USD $ and it already was in $ then nothing should change while If I chose LBP and the currency was in $ the price must be multiplied by 2000 and the symbol would change from $ to LBP, But the problem is that when I introduced this statement in JS the script stops on working (it was multiplying it by 2000):

A bioinformatics programming question. In R, I have a classic speciesA-to-speciesB gene symbol conversion, in this example from mouse to human, which I'm performing using biomaRt, and specifically the getLDS function.
...ANSWER
Answered 2020-Dec-03 at 14:47I believe a workaround could be retrieving all IDs from the Biomart database itself, here: https://www.ensembl.org/biomart/martview/
- Click on choose database -> Ensembl Genes
- Choose dataset -> your selected species (e.g. Mouse genes)
- Click on Results -> Check "Unique results only" -> Go
- Profit
The list retrieved here has currently 53605 ids, which is, I believe, what you need.
Enjoy!
QUESTION
I am trying to parse an xml file with golang.
I've used xsdgen to generate the struct part
I cannot parse the file with xml.Unmarshal(byteValue, &data)
I expected the program to print : GrandTotalAmount.Value which is 671.15 but it is printing 0.
The variable data
seems empty, as this line didn't worked as i expected :
xml.Unmarshal(byteValue, &data)
I haven't seen any errors compiling (or i don't know where to find them)
I feel like i am missing something, can you help me please ?

Answered 2020-Nov-21 at 17:46I think this is related to Go Issue #13400. There seems to be an issue with the namespace prefixes. You can in fact ignore the prefixes in your struct tags while Unmarshaling.
The following code should work for you:

Thanks in advance for any help. Not an expert in Linq to Sql by any means. I have 4 tables.
The main lb_item table which defines, unsurprisingly, an item. Many fields but holds 3 ID fields. itemID (key) categoryID (not null) patternID (can be null)
lb_pattern table which is keyed off the lb_item patternID.
lb_category table which is keyed off the lb_item categoryID.
lb_animal table which is keyed off the lb_item item ID.
So I need a select from the lb_item table joining to these other 3 tables to bring back varchar fields as I'm building a DTO.
A single left outer join works fine thus:
