If I change above name by capital S
If I will go to red error mark this error message I am getting
I am trying to find solution I didn’t find. My problem is in checkRule
If I haven’t write any validation for that error why xtext giving such
error. This Problem I got when my name starts with this Capital
letters error A, G, L, M, O, P, R, S, T, W. Is this my code issue or
xtext has some bugs or I am missing something?

Powershell running Java Script to Encrypt Password

We have a number of Lanier MFPs that use the scan-to-folder option to allow people to get their documents, and we are starting to implement more security measures on the AD passwords they use by forcing a password reset.
Unfortunately, the Laniers use a proprietary encryption for the passwords. I've managed to get a functional Java command that will encrypt passwords into this format. The problem I've been encountering is that I then have to get this encoded password into PowerShell to pass it to the scanner.
I can run the Java command through a command line, but can't pass the encrypted password back into PowerShell as a string that the printer will accept (it needs to be in Base64). If I do pass the encoded password back into PowerShell, then run it through PowerShell's Base64 creation process, it is, obviously, changed too much for the scanner to use it.
What I need to determine is whether there's a way for me to take the following command line command, and get it to run in PowerShell, then provide me its output so I can pass this to the printer.
java -cp ./commons-codec-1.10.jar;. cdm.GwpwesCharacterEncoding %pass% "gwpwes002"
The Java command outputs a Base64 string based on the following line:
return new String(Base64.encodeBase64((byte[])encrypt));
As an example, if I pass the text 'Test' into that, I get the string "HVhcmtla25meHVncHQ=="
This is useless to me, though, as I can't then get this back into PowerShell to pass through to the printer, and if I encode it as Base64 with PowerShell, it comes out as "MgBoAHMAWgBtADkAegBjADIAQgBxAGUAMABKAHgAWgBYAGgAbgBiAG0AMAB3AD0A".
Can anyone help?
Revised code after some assistance:
$pass1 = "test"
$path = "c:\Test\printercreds"
$encode = "gwpwes002"
cd $path
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pInfo.FileName = 'java'
$pInfo.Arguments = "-jar .\commons-codec-1.10.jar cdm.GwpwesCharacterEncoding $pass1 $encode"
$pInfo.UseShellExecute = $false
$pInfo.RedirectStandardOutput = $true
$pInfo.RedirectStandardError = $true
$process = New-Object System.Diagnostics.Process
$process.StartInfo = $pInfo
[void]$process.Start()
$passsec = $process.StandardOutput.ReadtoEnd()
$process.WaitforExit()
write-host $passsec

Please try this. Its the encoding for GWPWES002. I found a old java version here.
https://www.dropbox.com/s/3324g84x0l4bnon/GwpwesCharacterEncoding.java?dl=0
There is a weakness in this "encoding". The front part of the encoding is just random padding. the pack part is where the actual string is stored. Running the script on the same string just a few times points out this error.
encodeGwpwes002 -code "a"
generated this hashes
np6eWFieWJ6eWA==
np6eWJ5YWFieWA==
WFienlhYnlieWA==
nlhYnp5Ynp6eWA==
nlieWFieWJ6eWA==
everything up until eWA== is just random padding mean "eWA==" == "a"
same for "aaaaaaaa"
np5YWJ5YnlieWFhYWFhYWFg=
np5Ynp6eWJ6eWFhYWFhYWFg=
nlienp6eWJ6eWFhYWFhYWFg=
WJ5YWJ6enlieWFhYWFhYWFg=
Meaning that
"eWFhYWFhYWFg=" Is "aaaaaaaa".
the password you provided as "test", A example of manipulation would be :
HVhcmtla25meHVncHQ== IS "test" :: 29 88 92 154 217 90 219 153 158 29 89 220 29
HVhcmtla25meFVncHQ== IS "Test" :: 29 88 92 154 217 90 219 153 158 21 89 220 29

Start Java Application using System.Diagnostics.Process

$startCount = 5;
$processors = Get-WmiObject -Class Win32_ComputerSystem | select -
ExpandProperty "NumberOfLogicalProcessors";
$perInstance = $processors / $startCount;
$affinityloop = 1;
$affinityvalue = 0;
for($i=1; $i -le $startCount; $i++) {
$affinityvalue = 0;
for($u=1; $u -le $perInstance ; $u++) {
$affinityvalue = $affinityvalue + $affinityloop;
$affinityloop = $affinityloop * 2;
}
$ps = new-object System.Diagnostics.Process;
$ps.StartInfo.Filename = "C:\jdk\bin\java.exe";
$ps.StartInfo.Arguments = " -server -Xms10240m -Xmx10240m -XX:+UseG1GC -cp `".;*`" Worker";
$ps.start();
Write-Host $affinityvalue ;
$ps.ProcessorAffinity = [Convert]::ToString($affinityvalue, 16);
}
I am trying to start a Windows Java application on two different NUMA nodes. Has anyone able to accomplish this with Diagnostics.Process format? This code does work fine, but all applications created are on the same NUMA node and hence only using 50% power.
I tried codes such as $mod = ($i % 2); to help prepare for some way to alternate the NUMA node but unsure how to specify it within the script.
EDIT
Tried to load balance with ProcessorAffinity and I get crashes due to Double unable to convert to IntPtr
EDIT 2
So it looks like Windows Groups the processors past 64 into Groups. Can't seem to find a way to alter that like ProcessAffinity. I guess its just not that common. You can easily do it in Task manager, just need to find a way to do it in Powershell or similar.

Aerospike : Retrieve a set of keys from LDT Bin in one call

Suppose In my LDT(LargeMap) Bin I have following values,
key1, value1
key2, value2
key3, value3
key4, value4
. .
key50, value50
Now, I get my required data using following snippet :
Map<?, ?> myFinalRecord = new HashMap<?, ?>();
// First call to client to get the largeMap associated with the bin
LargeMap largeMap = myDemoClient.getLargeMap(myPolicy, myKey, myLDTBinName, null);
for (String myLDTKey : myRequiredKeysFromLDTBin) {
try {
// Here each get call results in one call to aerospike
myFinalRecord.putAll(largeMap.get(Value.get(myLDTKey)));
} catch (Exception e) {
log.warn("Key does not exist in LDT Bin");
}
}
The problem is here if myRequiredKeysFromLDTBin contains say 20 keys. Then largeMap.get(Value.get(myLDTKey)) will make 20 calls to aerospike.
Thus if I go by retrieval time of 1 ms per transaction , here my one call to retrieve 20 ids from a record will result in 20 calls to aerospike. This will increase my response time to approx. 20 ms !
So is there any way where I can just pass a set of ids to be retrieved from a LDT Bin and it takes only one call to do so ?

There is no direct API to do multi-get. A way of doing this would be call lmap API directly from server multiple time through UDF.
Example 'mymap.lua'
local lmap = require('ldt/lib_lmap');
function getmany(rec, binname, keys)
local resultmap = map()
local keycount = #keys
for i = 1,keycount,1 do
local rc = lmap.exists(rec, binname, keys[i])
if (rc == 1) then
resultmap[keys[i]] = lmap.get(rec, binname, keys[i]);
else
resultmap[keys[i]] = nil;
end
end
return resultmap;
end
Register this lua file
aql> register module 'mymap.lua'
OK, 1 module added.
aql> execute lmap.put('bin', 'c', 'd') on test.demo where PK='1'
+-----+
| put |
+-----+
| 0 |
+-----+
1 row in set (0.000 secs)
aql> execute lmap.put('bin', 'b', 'c') on test.demo where PK='1'
+-----+
| put |
+-----+
| 0 |
+-----+
1 row in set (0.001 secs)
aql> execute mymap.getmany('bin', 'JSON["b","a"]') on test.demo where PK='1'
+--------------------------+
| getmany |
+--------------------------+
| {"a":NIL, "b":{"b":"c"}} |
+--------------------------+
1 row in set (0.000 secs)
aql> execute mymap.getmany('bin', 'JSON["b","c"]') on test.demo where PK='1'
+--------------------------------+
| getmany |
+--------------------------------+
| {"b":{"b":"c"}, "c":{"c":"d"}} |
+--------------------------------+
1 row in set (0.000 secs)
Java Code to invoke this would be
try {
resultmap = myClient.execute(myPolicy, myKey, 'mymap', 'getmany', Value.get(myLDTBinName), Value.getAsList(myRequiredKeysFromLDTBin)
} catch (Exception e) {
log.warn("One of the key does not exist in LDT bin");
}
Value will be set if key exists and it would return NIL if it does not.

Complex regular expression

Consider the following regular expression :
^[:;][-^]\)$
List all the strings that exactly match this expression or, if there are more than ten such strings, describe them.

Assuming the close paren is spurious, here is a slick solution:
% echo {':',';'}{'-','^'}\)
:-) :^) ;-) ;^)
Which is of course:
% perl -le 'print for <{:,;}{-,^})>'
:-)
:^)
;-)
;^)
Isn’t that cool?
And then of course, there's this:
#!/usr/bin/perl
use 5.010 ;
$stdout = 124.102.109.116;
open
stdout ;
use less
${"\42"} = "\54" ;
say
for
#224 =
eval
join
/\/\/\/∖/ =>
map
{"<$_>"}
join
/\/\/\/∖/ =>
map
{"{#$_}" }
[qw{ | [ } ] =>
[qw{ : ; % # } ] =>
[qw{ ^ = * _ ~ } ] =>
[qw{ / v ) | o 3 I } ]
which delightfully produces this:
|:^/ |:^v |:^) |:^| |:^o |:^3 |:^I |:=/ |:=v |:=) |:=| |:=o |:=3
