2012-11-21 11:54:50.608 [10152:907] EmptyMark Image: <UIImage: 0x20819ae0>
After App Enters the background and comes back to foreground.
2012-11-21 11:54:57.040 [10152:907] Current Image: <UIImage: 0x20819ae0>
2012-11-21 11:54:57.042 [10152:907] EmptyMark Image: <UIImage: 0x208cc580>
I'm comparing the same image "emptymark.png" it is added to a button "Current Image" (logged) to the actual file "EmptyMark Image" (Logged) when I come back to the app after it has been in the background EmptyMark returns different from "Current Image" (the image on the button).
I'm getting "EmptyMark Image" using [UIImage imageNamed:@"emptymark.png"]
Should I be holding a reference to emptymark.png all the time rather then trying to compare from the file?
A: You can hold the reference to UIImage as,
self.image = [UIImage imageNamed:@"emptymark.png"];
When you are comparing using just [UIImage imageNamed:@"emptymark.png"], it is creating separate objects.

Can I instantiate "core.sv" in both (riscv_top_tb.sv and tracelog.sv)?
This is my TestBench file: riscv_top_tb.sv
genvar r;
generate
for (r = 1; r < 32; r++) begin : gen_mprf_assign
assign rv_vip_rf_if.x[r] = RISK_V.bancoDeRegistros.bancoReg[r];
end : gen_mprf_assign
endgenerate
//------------------------------------------------------------------------------
// Core instance
//------------------------------------------------------------------------------
core #(.RamSize(RamSize)) RISK_V
(
.CLK(CLK),
.RESET_N(RESET_N),
.IMEM_DIR(dir_rom),
.IMEM_DATA(data_rom),
.DMEM_DIR(dir_ram),
.DMEM_DATA_R(dataR_ram),
.DMEM_DATA_W(dataW_ram),
.I_READ(I_READ),
.D_READ(D_READ),
.D_WRITE(D_WRITE)
);
And this is my tracelog file: tracelog.sv
core #(.RamSize(RamSize)) RISK_V
(
.CLK(CLK),
.RESET_N(RESET_N),
.IMEM_DIR(dir_rom),
.IMEM_DATA(data_rom),
.DMEM_DIR(dir_ram),
.DMEM_DATA_R(dataR_ram),
.DMEM_DATA_W(dataW_ram),
.I_READ(I_READ),
.D_READ(D_READ),
.D_WRITE(D_WRITE)
);
assign mprf_int_alias.INT_00_ZERO = '0;
assign mprf_int_alias.INT_01_RA = RISK_V.bancoDeRegistros.bancoReg[1];
assign mprf_int_alias.INT_02_SP = RISK_V.bancoDeRegistros.bancoReg[2];
If this is not possible, how should I do it?
A: I'm not sure what you're trying to do, but it very much sounds like you're trying to copy the file in both TB and tracelog. In that case, you can simply do
`include "risk_v_instantiation.sv"
where the "risk_v_instantiation.sv" file has the text:
core #(.RamSize(RamSize)) RISK_V
(
.CLK(CLK),
.RESET_N(RESET_N),
.IMEM_DIR(dir_rom),
.IMEM_DATA(data_rom),
.DMEM_DIR(dir_ram),
.DMEM_DATA_R(dataR_ram),
.DMEM_DATA_W(dataW_ram),
.I_READ(I_READ),
.D_READ(D_READ),
.D_WRITE(D_WRITE)
);
You still have to handle signal declarations which you may be able to add to this file.
A: You cannot instantiate a file anywhere. You can instantiate a module. A module can be instantiated inside another module. This way you build a hierarchy of module instances.
There is always a top-level module(s) which is not instantiated by anything else, or defined by other means. Your hierarchy starts with this module and branches down to other instances.
Testbench is usually instantiated as a part of this hierarchy (though it might have its own top).
You can instantiate the same module in different hierarchies or multiple times in the same hierarchy (varying instance names).
From a test bench you can access variables in any part of the hierarchy, using cross-module-references (xmr). You just need to provide the hierarchy path to the instance you are interested int.
So, answering your question: yes, you can instantiate the same core module in different hierarchies. However there will be 2 different instances with in different levels of hierarchy with their own inputs, outputs, variables, and parameters. They will have different instance paths (despite that you name the local instances the same) and will require different xmr access paths to their internals.

libraryDependencies ++= Seq(

The result is

How can I find the correct oracle realm?
Unable to find credentials for [OAM 11g @ login.oracle.com]
would suggest that OAM 11g is the realm, but that still results in the same problem. Also the https://blogs.oracle.com/dev2dev/get-oracle-jdbc-drivers-and-ucp-from-oracle-maven-repository-without-ides suggested OAM 11g does not work.
For gradle, there seems to be a workaround: https://groups.google.com/forum/#!topic/gradle-dev/G8X_41lOIlU
maven {
url 'https://www.oracle.com/content/secure/maven/content'
credentials {
username 'user'
password 'password'
}
but so far I could not get any option (correct realm via SSO, workaround) to work with SBT.
edit2
The best workaround so far is Find Oracle JDBC driver in Maven repository
edit3
find a reproducible example here:
https://github.com/geoHeil/oracleJBCMavenSBT
A: 1) I checkout your project on github
2) I run this command for find the path of my Maven installation:
mvn -version
3) I edit the ....\apache-maven-3.5.0\conf\settings.xml file with your setting
4) I run this command:
mvn clean install
5) I have the same error
6) I valid my account on Oracle official Web site
7) I edit the ....\apache-maven-3.5.0\conf\settings.xml file with my valid login/password
8) I run this command and I have a Maven BUILD SUCCESS:
mvn clean install
You need valid your Oracle account for resolve your problem.
Note:
If you use travic-ci, run this command:
mvn clean install --settings settings.xml
In your settings.xml file:
<server>
<id>maven.oracle.com</id>
<username>${OTN_USERNAME}</username>
<password>${OTN_PASSWORD}</password>
<configuration>
<basicAuthScope>
<host>ANY</host>
<port>ANY</port>
<realm>OAM 11g</realm>
</basicAuthScope>
<httpConfiguration>
<all>
<params>
<property>
<name>http.protocol.allow-circular-redirects</name>
<value>%b,true</value>
</property>
</params>
</all>
</httpConfiguration>
</configuration>
</server>
in travic-ci, add 2 environment variables (https://travis-ci.org/YOUTORGANIZATION/YOURREPOSITORY/settings) :
A: ...
resolvers += "OAM 11g" at "https://maven.oracle.com",
credentials += Credentials("OAM 11g", "login.oracle.com", "mail", "pass"),
libraryDependencies += "com.oracle.jdbc" % "ojdbc8" % "18.3.0.0" exclude("com.oracle.jdbc", "ucp"),
...
It works.

Environment: .NET 6
The function does different tasks such as
*
*generate a transaction ID
*Fetch data from Db based on an input parameter
*Transform the data
*Write the transformed data into DB
*Write the transformed data into service bus topic
When all these steps finishes, it needs to write the log into a service bus queue.
Also the execution happens at function level as well as application layer
For example the ID created immediately when Azure function being hit. Tranformation happens at application layer project.
But I need to hold all these information into a single object and that object I am going to write into a service bus queue as a JSON message.
Here is my class definition.
Public class ServiceMessage
{
public Guid Id { get; set; }
public int ProcessId { get; set; }
public object? ProcessExecutionId { get; set; }
public string? PrimaryObjectName { get; set; }
public string? ServiceName { get; set; }
public Status Status { get; set; }
public List<Message>? Message { get; set; }
}
public sealed class Message
{
public Status Status { get; set; }
public string? Remarks { get; set; }
public string? Timestamp { get; set; }
}
public enum Status
{
Failure = 0,
InProgress = 1,
Success = 2
}
While application progressing, I need to set each of these properties. Also there is a Message Array which is for holding any specific messages/error while any stages of the processing.
I dont know how to handle this situation.
I thought about declaring an object initially and passing the same object to different methods and there it got updated and that methods return back the object and the same for everywhere. But I believe its a bad approach.
Could you please help me to handle this.

How resolve this?
More
According with the 3rd output there is available/suggested the following link for more details
*
*https://www.jenkins.io/redirect/troubleshooting/java.awt.headless
Which it targets to:
*
*Jenkins got java.awt.headless problem
it indicates to install (for my case)
*
*sudo apt install ttf-dejavu
*sudo apt install xvfb
It does not work
A: Thanks to the following link at Jenkins Jira
*
*AWT initialized even with -Djava.awt.headless=true
Is mandatory install fontconfig[.x86_64], so was just enough execute
*
*sudo apt install fontconfig
Note in jira was really suggested to install fontconfig.x86_64 but it does not exist on Ubuntu repositories. Perhaps is available for other distributions. So one of them should be viable, either fontconfig or fontconfig.x86_64
Once installed execute in peace:
*
*java -jar jenkins.war --httpPort=9090 (is not need it -Djava.awt.headless=true )
A: As you aren't using LTS, errors like this one could appear. My proposition is to use LTS version. Currently the latest one is 2.289.2
Maybe changing java 11 to 8 version could help, but I'm not sured about it.

Initially, I was getting 'java.lang.NoClassDefFoundError: java/sql/SQLException' exception and so I added 'requires java.sql' after seeing this as a suggested solution elsewhere on Stack Overflow, but now a the exception described above arises. I'm not sure where I'm gone wrong in my code or what is missing.
Here is my module-info.java file:

word1.setUnitID(1);
word1.setWord("test");
word1.setVocabClass("noun");
word1.setVocabDefinition("this is a test");
word1.setVocabID(7);
System.out.println(word1.getUnitID());

}
e.printStackTrace();

I'm using intelliJ ultimate 2019.1 and language level is set to 11.
A: I finally managed to solve the issue by updating my module-info.java file to include:
module AlienDB {
requires static lombok;
requires java.persistence;
requires org.hibernate.orm.core;
requires java.naming;
requires java.sql;
requires com.sun.xml.bind;
requires net.bytebuddy;
opens Aliens to org.hibernate.orm.core;
exports Aliens;
}
Previously I was adding java.xml.bind which was causing further issues.

My code looks like this:
public class XMLParser
{
String streamTitle = "";
/** Called when the activity is first created.
* @throws IOException
* @throws SAXException */
public String startparse(String xml) throws SAXException, IOException
{
DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
try
{
DocumentBuilder builder = builderFactory.newDocumentBuilder();
builder.parse(xml);
}
catch (ParserConfigurationException e)
{
e.printStackTrace();
}
return builderFactory.getAttribute("WhoisRecord").toString();
}
}
when i try to return something from startparse i simple get nothing.
XMLParser xmlpar = new XMLParser();
Log.v("Faruk TEST ", "udss:"+xmlpar.startparse(temp));
Do some one know a simple solution for this problem?
A: Try this i hope it is what you are looking for ...
Android: parse XML from string problems
A: I think that your call to builderFactory.getAttribute is wrong.
DocumentBuilder.parse() returns a Document object, and this will contain the DOM that you've just parsed. You can use this to access the elements of the XML.
A: Try this Working with XML-Android

I have my MongoClient as (example):

And would like to check if it is running or not.

<ul class="ul">
<li class="li">
<a>Some buddy</a>
<ul class="ul">
<li class="li" id="testLi">
<a id="testView">test buddy</a>
</li>
</ul>
</li>
</ul>
Please ignore class names. I have assigned ids to <li> and child` tags. and I also have a function written as bellow:
$(document).ready(function () {
$('#testView').click(function () {
var ul = document.createElement('ul');
ul.className = 'ul';
var li = document.createElement('li');
li.className = 'li';
var a = document.createElement('a');
a.innerHTML = 'test buddy';
$(li).append(a);
$(ul).append(li);
$('#testLi').append(ul);
});
});
Now if I click on <a id="testView">test buddy</a> my function does not get called. I think this because DOM is loaded and my new elements are get created in ready(). Please provide a solution.
A: You will need to attach the event handler to the document and delegate the event to the element.
You can do something like this:
$(document).on('click', '#testView', function () {
var ul = document.createElement('ul');
ul.className = 'ul';
var li = document.createElement('li');
li.className = 'li';
var a = document.createElement('a');
a.innerHTML = 'test buddy';
$(li).append(a);
$(ul).append(li);
$('#testLi').append(ul);
});
This will apply to all the elements with this id regardless of whether they are created before document.ready() or not.
A: Your code is working fine. I have added it to the snippet below.
$(document).ready(function() {
$('#testView').click(function() {
var ul = document.createElement('ul');
ul.className = 'ul';
var li = document.createElement('li');
li.className = 'li';
var a = document.createElement('a');
a.innerHTML = 'test buddy';
$(li).append(a);
$(ul).append(li);
$('#testLi').append(ul);
});
});

<ul class="ul">
<li class="li" id="testLi">

You are searching for <b style="font-family:Zawgyi-One"><?php echo $spre; ?> - <?php echo $sone; ?><?php echo $stwo; ?><?php echo $sthree; ?><?php echo $sfour; ?><?php echo $sfive; ?><?php echo $ssix; ?></b><br /><br />
</html>
<?php
print ("$output <br />");
?>
But when I search, the result was shown in
You are searching for c1 - 000000
But I like to show "c1" as က (က is unicode). And I will import CSV file into my database without including unicode.
A: The content of the value="" is what the Browser send to PHP, if you want to see exactly whats in the option then code it like
<select name="name">
<option value="Joe">Joe</option>
<option value="Micheal">Micheal</option>
<option value="Sean">Sean</option>
</select>
However it is normal to code something like an id in the value="<?php echo $id;?>" as then you can retrieve the data associated with the name more easily.
Ah I just noticed that you said you were using multiple choice or wanted too at least.
In that case you need to change the <select> tag like so
<select name="name" multiple="multiple">
<option value="Joe">Joe</option>
<option value="Micheal">Micheal</option>
<option value="Sean">Sean</option>
</select>
Then in your PHP code the $_POST['name'] variable will be returned as an array, so you would processing like this :-
if ( isset( $_POST['name'] ) ) {
foreach ( $_POST['name'] as $selected_name ) {
echo $selected_name;
}
}

Now the attached message has two content-type values. Email comes with just text and with no image.
I have done it successfully with MultiPart class, but looking to achieve that with EmailMessage.
A: It is really a pity that Python docs on this subject are incomplete/wrong. I wanted to do the same thing and got the same problem (attachments got two content-types)
Solved the problem by using the attach() method instead of add_attachment() on EmailMessage objects. The only caveat is that you have to transform the EmailMessage to multipart/mixed type before doing this. An example:
from smtplib import SMTP
from email.message import EmailMessage
from email.mime.text import MIMEText
from email.headerregistry import Address
from ssl import SSLContext, PROTOCOL_TLSv1_2
# Creating and populating email data:
msg = EmailMessage()
msg['From'] = Address(display_name='Recipient', addr_spec='rcpt@example.org')
msg['To'] = Address(display_name='Sender', addr_spec='sender@example.org')
msg['Subject'] = 'An email for you'
msg.set_content('This should be in the email body')
# It is possible to use msg.add_alternative() to add HTML content too
# Attaching content:
att = MIMEText('This should be in an attached file') # Or use MIMEImage, etc
# The following line is to control the filename of the attached file
att.add_header('Content-Disposition', 'attachment', filename='attachment.txt')
msg.make_mixed() # This converts the message to multipart/mixed
msg.attach(att) # Don't forget to convert the message to multipart first!
# Sending the email:
with SMTP(host='smtp.example.org', port=587) as smtp_server:
try:
# You can choose SSL/TLS encryption protocol to use as shown
# or just call starttls() without parameters
smtp_server.starttls(context=SSLContext(PROTOCOL_TLSv1_2))
smtp_server.login(user='user@smtp.example.org', password='password')
smtp_server.send_message(msg)
except Exception as e:
print('Error sending email. Details: {} - {}'.format(e.__class__, e))

With the gaussian fit, I have no problem of value.
Here's a print of my plot :
I don't know what I'm doing wrong in my code for obtaining the mean of my exponential fit:
plt.figure(1)
plt.subplot(221)
cycle = map(float,cycle)
cycle = np.array(cycle)
list_cycle1 = cycle[cycle < 1000 ]
list_cycle2 = cycle[cycle >= 1000]
plt.hist(list_cycle1, bins=10, normed=True)
xt1 = plt.xticks()[0]
xmin1, xmax1= min(xt1), max(xt1)
lnspc1 = np.linspace(xmin1, xmax1, len(list_cycle1))
m1, s1 = stats.expon.fit(list_cycle1, moments='mv')
pdf_e = stats.expon.pdf(lnspc1, m1, s1)
plt.plot(lnspc1, pdf_e, label='expon pdf')
list_mean_1.append(m1)
list_se_1.append(s1)
plt.hist(list_cycle2, bins=10, normed=True)
xt2 = plt.xticks()[0]
xmin2, xmax2= min(xt2), max(xt2)
lnspc2 = np.linspace(xmin2, xmax2, len(list_cycle2))
m2, s2 = stats.norm.fit(list_cycle2)
pdf_g = stats.norm.pdf(lnspc2, m2, s2)
plt.plot(lnspc2, pdf_g, label="Norm")
list_mean_2.append(m2)
list_se_2.append(s2)
I could add an example of list_cycle1 and list_cycle2 if you want.
PS: I read this SciPy documentation and I don't understand where I fail in my code to obtain the mean of my exponential fit.
A: stats.expon.fit returns the tuple (loc, scale). According to the doc,
scale = 1 / lambda
which is also the mean of the exponential distribution. Therefore, it is the second parameter that you want.
If you want to force the location to be 0, you can pass in the floc parameter to fit.

I cannot, however, access this same FTPS server from R using the RCurl library (R version=3.4.3, RCurl version = 1.95-4.9, windows 7 PC). I expect it has something to do with my invocation of getURL(). Here's what happens when I try to list the files in a directory on the FTPS server:
library(RCurl)
url <- "FTPS://<myIpaddress>/<path>/"
userpwd <- "myname:mypasswd"
filenames <- getURL(url, userpwd=userpwd, ftp.use.epsv = FALSE, dirlistonly = TRUE, .opts=curlOptions(verbose=TRUE))
It complains about connection refused on port 990 (presumably the default port for FTPS?). I happen to have the FTPS server setup to use port 21. Filezilla didn't require a port number so I had left it out here too. Explicitly specifying port 21, however, gives another problem...
url <- "FTPS://<myIpaddress>:21/<path>/"
This time the complaint is about "unknown protocol". Don't understand. I am using a FTPS server listening on port 21, I specify the same on the URL. What could be wrong?
Can anyone recommend some ways to troubleshoot this further?
For completeness here's the FTPS server configuration (it's a synology diskstation NAS)...
A: Add ftp.ssl = TRUE to the getURL options for SFTP.
This is the equivalent of --ftp-ssl in actual curl.

(in script):
var response = [{
"A":"a2",
"B":"b2",
"C":"c2"
},
{
"A":"a3",
"B":"b3",
"C":"c3"
},
{
"A":"a4",
"B":"b4",
"C":"c4"
}];
$.each(response, function(i, item) {
$('<tr>').html(
//"<tr>" +
"<td>" + response[i].A + "</td><td>" + response[i].B + "</td><td>" + response[i].C + "</td>" + "</tr>").appendTo('#MyTable tbody');
});
and I want to change one of column (just for exp it's will be "A") to be "edited" by text-box.
I am tring this:
... `"<td><input type="text">" + response[i].A + "</td><td>" + response[i].B + "</td><td>" + response[i].C + "</td>" + "</tr>").appendTo('#MyTable tbody');`...
but it's not working.
any help please!
A: Try saying This
var firstcell = "<td><input type="text" value="VALUE"</td>";
firstcell = firstcell.replace('VALUE', response[i].A);
Use this for first cell in each Row. After that append this in whole row.
A: If i understood correctly,
Instead of creating <tr>, later adding contents to it using html() and finally appending to do the <table>, you can directly add everything altogether to the <table> using append() method.
$.each(response, function(i, item) {
$('#MyTable tbody').append("<tr>"
+"<td><input type='text' value='"+ response[i].A +"'/> </td><td><input type='text' value='"+ response[i].B +"'/></td><td><input type='text' value='"+ response[i].C +"'/></td>"
+ "</tr>");
});

I have not changed anything in the adapter and as I could see when I remove
android:background="?activatableItemBackground"
it works. Do you have an idea what's the problem, I'm researching for hours but I can only think on an Android bug.
This is my attrs.xml
<resources>
<attr name="state_red" format="boolean" />
<attr name="state_yellow" format="boolean" />
<!--
The ListItems reference this as background. In the styles.xml is this reference linked to an xml selector that controls
the color of the view according to states.
-->
<declare-styleable name="BaseTheme">
<attr name="activatableItemBackground" format="reference" />
</declare-styleable>
</resources>
A: And as always, a short time after asking you get the solution by yourself: The problem was really strange, in my styles.xml I had following:
<!-- Immediate parent theme to specify base values for custom attributes -->
<style name="Theme.Base" parent="FrameworkRoot.Theme">
<!-- Defines the selector for the row view -->
<item name="activatableItemBackground">@drawable/dna_list_selector_holo_light</item>
</style>
After reading somewhere that name collision is a possibility in styles I changed Theme.Base by Custom_Base_Thme and now it works, it was the only change I made.

def csv_import
require 'csv'
file = File.open("/#{Rails.public_path}/uploads/shate.csv")
csv = CSV.open(file, "r:ISO-8859-15:UTF-8", {:col_sep => ";", :row_sep => :auto, :headers => :first_row})
csv.each do |row|
end
end
Could anybody help me increase the speed using fastercsv?
A: As it's name implies Faster CSV is Well Faster :)
http://fastercsv.rubyforge.org
also see. for some more info
Ruby on Rails Moving from CSV to FasterCSV
A: I don't think it will get much faster.
That said, some testing shows that a significant part of time is spent for the transcoding (about 15% for my test case). So if you could skip that (e.g. by creating the CSV in UTF-8 already) you would see some improvement.
Besides, according to ruby-doc.org the "primary" interface for reading CSVs is
foreach, so this should be preferred:
def csv_import
import 'csv'
CSV.foreach("/#{Rails.public_path}/uploads/shate.csv", {:encoding => 'ISO-8859-15:UTF-8', :col_sep => ';', :row_sep => :auto, :headers => :first_row}) do | row |
# use row here...
end
end
Update
You could also try splitting the parsing into several threads. I reached some performance increase experimenting with this code (treatment of heading left out):
N = 10000
def csv_import
all_lines = File.read("/#{Rails.public_path}/uploads/shate.csv").lines
# parts will contain the parsed CSV data of the different chunks/slices
# threads will contain the threads
parts, threads = [], []
# iterate over chunks/slices of N lines of the CSV file
all_lines.each_slice(N) do | plines |
# add an array object for the current chunk to parts
parts << result = []
# create a thread for parsing the current chunk, hand it over the chunk
# and the current parts sub-array
threads << Thread.new(plines.join, result) do | tsrc, tresult |
# parse the chunk
parsed = CSV.parse(tsrc, {:encoding => 'ISO-8859-15:UTF-8', :col_sep => ";", :row_sep => :auto})
# add the parsed data to the parts sub-array
tresult.replace(parsed.to_a)
end
end
# wait for all threads to finish
threads.each(&:join)
# merge all the parts sub-arrays into one big array and iterate over it
parts.flatten(1).each do | row |
# use row (Array)
end
end
This splits the input into chunks of 10000 lines and creates a parsing thread for each of the chunks. Each threads gets handed over a sub-array in the array parts for storing its result. When all threads are finished (after threads.each(&:join)) the results of all chunks in parts are joint and that's it.
A: I'm curious how big the file is, and how many columns it has.
Using CSV.foreach is the preferred way. It would be interesting to see the memory profile as your app is running. (Sometimes the slowness is due to printing, so make sure you don't do more of that than you need)
You might be able to preprocess it, and exclude any row that doesn't have the esupp, as it looks like your code only cares about those rows. Also, you could truncate any right-side columns you don't care about.
Another technique would be to gather up the unique components and put them in a hash. Seems like you are firing the same query multiple times.
You just need to profile it and see where it's spending its time.
A: check out the Gem smarter_csv! It can read CSV files in chunks, and you can then create Resque jobs to further process and insert those chunks into a database.

gcc does seem available, and I can compile an sample iphone project on xcode
Any ideas?
A: Such things can happen when:
a) Installing Xcode 4.3[.1] and when Xcode 4.2 is removed (the installer ask for this) or if it was never installed.
To fix this you need to install the optional "Command Line Tools" to get a complete installation.
You can do this from inside Xcode using those steps: XCode 4.3 Command Line Tools Package with Invalid Checksum
b) when you install Xcode in a non-default directory. In this case you'll need to tell MonoDevelop where the Apple SDK is located. You can change this in the MonoDevelop's preferences dialog, SDK locations.

disk is full and cant log any more lines, shutdown the application.
So what i need some pre checks before the log events, and if logger does these checks by itself i need those informations
A: The standard appenders in log4j2 do not perform checks before writing. They would be expensive and still wouldn’t guarantee the log record could be written
A: In addition to Ralph’s answer, Log4j2 is designed as an audit logging framework. This means that if logging is critical to your application, such that the application should fail if logging failed, Log4j2 can accomplish this.
All built-in appenders have a configuration attribute ignoreExceptions for this purpose. From the manual:
The default is true, causing exceptions encountered while appending events to be internally logged and then ignored. When set to false exceptions will be propagated to the caller, instead.

I want to count the number of times each word appears in a body of text. I can do this with a simple regular expression.
However, I have another list of words that capture context. In the example below the context is a list of pets. Let's call this WORD_LIST_2.
I'd like to count the number of times each of the words in WORD_LIST_1 that are within X number of words of any of the words in WORK_LIST_2.
My strategy is to extract the matches to WORD_LIST_1 words into an array using a regular expression and then create hash that counts the number of times each word is in this array.
I can do easily when the context word (WORD_LIST_2) follows the WORD_LIST_1 word.
However, I run into a problem when the WORD_LIST_2 word appears before the WORD_LIST_1 words, specifically when there multiple WORD_LIST_2 words.
Below is the code.
#!/usr/bin/perl -w
#use strict;
@colors = ("red", "blue", "green", "brown");
$WORD_LIST_1 = join("|",@colors);
@pets = ("cat","dog","bird","fish");
$WORD_LIST_2 = join("|",@pets);
#$text1 = "The red haired dog quickly and sharply ran away from the blue nosed cat.";
#$text1 = "The green spotted cat drinks blue water.";
#$text1 = "The brown feathered, green beaked bird flew away.";
$text1 = "The fish with blue fins and red tails.";
@finds = ();
$within_N_words = 4;
@finds = $text1 =~ m/\b(?=($WORD_LIST_1)\W+(?:\w+\W+){0,$within_N_words}?(?:$WORD_LIST_2))\b|\b(?=(?:$WORD_LIST_2)\W+(?:\w+\W+){0,$within_N_words}?($WORD_LIST_1))\b/gi;
@finds = grep defined, @finds;
print "\n\n", join("|", @finds), "\n\n";
Note that the fourth $text1 line has blue and red following fish. But it only returns "blue" and doesn't return "red" too. I've check the first three sentences that are commented out and they appear to be working well.
My approach is based on this page: http://www.regular-expressions.info/near.html
Thoughts I've considered includd using a positive look-behind, but I need to have variable lengths in the look behind.
I've thought about reversing the entire text string and regular expression, then searching again. But this could result in double counting.
I've also thought about searching for each WORD_LIST_1 word in individual regular expersions using some sort of loop.
However, this takes a lot of time on my real data as the actual WORD_LIST_1 list is 500 or so words and I have multiple bodies of length text I want to search.
Two other side notes:
(1)the regular expression above occasionally returns empty elements into the @finds array. I can't figure out why. My work around is to use the grep defined line. What is the correct way to address this. Rather, why is my regular expression returning blank elements?
(2) I'm still learning the "proper" way to use PERL. I've commented out use strict in this example as I don't believe in the context I am using perl it makes a difference. I'm sure someone can tell me why this is wrong of me. Good PERL programmers always seem to tell me I shouldn't run perl code without using strict, but no one yet has convinced me it is something I need to worry about. However, I'm open to learning.
A: Well, first off - the text you give... looks like red is more than 4 words away from fish in the first place?
But failing that - the problem is I think because your regex is "consuming" the text on the first match so it doesn't it the second match.
In this, you start to hit the limitations of the regular expression engine - http://www.regular-expressions.info/keep.html
How important is it that you use a single regular expression to do your search? Bear in mind that whilst a regular expression looks quite concise, it can be hard to read and computationally expensive.
I would suggest therefore that your initial suggestion of splitting up your patterns isn't as bad as it sounds - in order to match 'red' and 'blue' on the second example, you need to allow for the conditions that'll permit duplicate matches.
E.g.
fish cat red red blue blue
How many hits should you get here? You can use something like a hash to count duplicates of words and deduplicate 'relationships' though:
my %matches = (
$text1 =~ m/
\b
($WORD_LIST_2)
\W+
(?:\w+\W+){0,$within_N_words}?
($WORD_LIST_1)\b
/gix
);
print Dumper \%matches;
We match into a hash, because then when we 'insert' paired words, we get key-value pairs:
$VAR1 = {
'fish' => 'blue'
};
But it may be of use to know - you can use qr in perl to "compile" a regex and see what you actually end up with.
In your example:
print qr /\b(?=($WORD_LIST_1)\W+(?:\w+\W+){0,$within_N_words}?(?:$WORD_LIST_2))\b|\b(?=(?:$WORD_LIST_2)\W+(?:\w+\W+){0,$within_N_words}?($WORD_LIST_1))\b/;
(?^:\b(?=(red|blue|green|brown)\W+(?:\w+\W+){0,4}?(?:(?^:cat|dog|bird|fish)))\b|\b(?=(?:(?^:cat|dog|bird|fish))\W+(?:\w+\W+){0,4}?(red|blue|green|brown))\b)
The first pattern doesn't match at all.
The second does, but only once because it 'eats' the existing patterns.
my @finds2 = ( $text1 =~ m/\b(?:$WORD_LIST_2)\W+(?:\w+\W+){0,$within_N_words}?($WORD_LIST_1)\b/gi )
Finds blue. Drop the 'nongreedy' modifier, and it'll find red. But because your pattern has 'eaten' the preceeding bits, it can't match twice with the g modifier.
I don't think perl will support multi-matching in that context, because if you think about it, the number of comparisons needed quickly gets huge.
I would also offer:
*
*check out the x modifier for writing your regexes when they get long.
*You can compile regexes, and it's advantageous when using variables that are effectively static (like you are).
So something like this:
my @pets = qw (cat dog bird fish );
my $WORD_LIST_2 = join( "|", map {quotemeta} @pets );
$WORD_LIST_2 = qr/$WORD_LIST_2/;
my @finds2 = (
$text1 =~ m/
\b
(?:$WORD_LIST_2)
\W+
(?:\w+\W+){0,$within_N_words}?
($WORD_LIST_1)\b
/gix
);
For 1: Because your capturing is both 'sides' of the alternation, but only one can match. So the one that doesn't returns undef. Split your pattern into two, and you won't have this problem. Or use ?| for branch reset. http://www.effectiveperlprogramming.com/2010/09/use-branch-reset-grouping-to-number-captures-in-alternations/
For 2: Why use strict and warnings?
So I'd suggest ending up with something like:
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
my @colors = qw ( red blue green brown );
my $WORD_LIST_1 = join( "|", map {quotemeta} @colors );
$WORD_LIST_1 = qr/$WORD_LIST_1/;
my @pets = qw (cat dog bird fish );
my $WORD_LIST_2 = join( "|", map {quotemeta} @pets );
$WORD_LIST_2 = qr/$WORD_LIST_2/;
my $within_N_words = 4;
while ( my $text1 = <DATA> ) {
print $text1;
my %matches = (
$text1 =~ m/(?|
\b #word break
($WORD_LIST_2)
\W+
(?:\w+\W+){0,$within_N_words}? #nongreedy 0-N 'words'.
($WORD_LIST_1)
\b
|
\b
($WORD_LIST_1)
\W+
(?:\w+\W+){0,$within_N_words}?
($WORD_LIST_2)
\b
)
/gix
);
print Dumper \%matches;
}
__DATA__
The red haired dog quickly and sharply ran away from the blue nosed cat.
The green spotted cat drinks blue water.
The brown feathered, green beaked bird flew away.
The fish with blue fins and red tails.
This gives us both words and context:
The red haired dog quickly and sharply ran away from the blue nosed cat.
$VAR1 = {
'blue' => 'cat',
'red' => 'dog'
};
The green spotted cat drinks blue water.
$VAR1 = {
'green' => 'cat'
};
The brown feathered, green beaked bird flew away.
$VAR1 = {
'brown' => 'bird'
};
The fish with blue fins and red tails.
$VAR1 = {
'fish' => 'blue'
};
(You can use values to extract just the words).

How thread-safe is enum in java?
Let there be an enum class like
public enum Type
{
ONE, TWO, THREE, FOUR
}
Is the Type.values() array thread safe to access in a for loop, e.g., in a static method? For example:
public static void process()
{
for (Type type:Type.values())
{
// Do something
}
}
Furthermore, if one defines a static array variable with any subset of these values, will that be thread safe to read? For example:
public static final Type[] TYPES = new Type[] {TWO, THREE};
public static void process()
{
for (Type type:TYPES)
{
// Do something
}
}
In both cases, the process() method may belong to a different class than the definition of the Type enum and of the types array.
Also, the TYPES array could be defined once in the Type enum and returned by a static method of that enum.
So, given the above, if multiple threads are running the process() method simultaneously, will the code be thread safe (at least for just reading the values of the TYPES array)?
A: The method Type.values() returns a new array every time. It does this because the array is mutable and it has to return a new copy each time to be thread safe.
A: enum are guaranteed thread-safe they are immutable. So, threads can't modify the state of the enum.
Second case, when you define as final, there also it will be threadsafe, you are not allowed to modify the reference of error.
Remember, you are not allowed to change the "reference" only, but you can change the state of array.
A: Others have already pointed out that the values() method returns a new array each time, so it is thread safe.
However, to answer your second question:
if one defines a static array variable with any subset of these values, will that be thread safe?
No. Any public static array is not safe, because array elements are always mutable.
That is, any thread could change TYPES[0] to be any other Type, which is not safe in the presence of multiple threads -- or indeed even in a single-threaded program.
Much better would be to expose a List<Type>, which can then be safely made immutable (e.g., using Collections.unmodifiableList()).

while (node.firstChild) {
node.removeChild(node.firstChild);
}
}
function summariseTable(tableId) {
var tbody = document.getElementById(tableId).lastElementChild,
reduced = Array.prototype.map.call(tbody.getElementsByTagName('tr'), function (element) {
return {
code: element.firstElementChild.textContent,
SqIn: +(element.lastElementChild.textContent)
};
}).reduce(function (acc, rowData) {
if (!acc.hasOwnProperty(rowData.code)) {
acc[rowData.code] = rowData.SqIn;
} else {
acc[rowData.code] += rowData.SqIn;
}
return acc;
}, {});
emptyNode(tbody);
Object.keys(reduced).forEach(function (code) {
var row = document.createElement('tr'),
tdCode = document.createElement('td'),
tdSqIn = document.createElement('td');
tdCode.appendChild(document.createTextNode(code));
tdSqIn.appendChild(document.createTextNode(reduced[code]));
row.appendChild(tdCode);
row.appendChild(tdSqIn);
tbody.appendChild(row);
});
}
document.getElementById('summarise').addEventListener('click', function () {
summariseTable('myTable');
}, false);
On jsFiddle
This example replaces the content of the current table, but you can easily have it create a new table instead. If you have inputs in the tds then get the value of those instead.

$stateProvider
.state('calendar', {
url: '/calendar/:category/:competition/:team',
controller: 'calendarCtrl',
templateUrl: 'app/modules/calendar/calendarView.html',
})
To make my navigation work I also need access to the :category/:competition/:team-params in my pageCtrl. Can I configure this using the same way? Something like:
$stateProvider
.state("page", {
abstract: true,
controller: 'pageCtrl',
// params: :category/:competition/:team
})
Edit: Using $stateParams in the calendarCtrl works fine. I just can't figure out how I can make sure my pageCtrl also can get read the url.
A: Since you're using ui.router, inject $stateParams in your controller(s) and then you can access those values like so:
controller.js
function($stateParams){
$stateParams.category
$stateParams.competition
$stateParams.team
A: My suggestion would be - use more views - the UI-Router built feature.
Multiple Named Views
There is a working plunker
Let's have the 'Parent' state which has this template:
This blue is the parent template. Orange are child views
<!-- HERE is one named view target -->
<div ui-view="title">This is a title filled by child having access to param</div>
...
<!-- HERE is other view target un-named -->
<div ui-view></div>
And its state is very simple. The interesting is the child state, which is taking care about both views:
.state('parent', {
abstract: true,
url: "/parent",
templateUrl: 'tpl.parent.html',
})
.state('parent.child', {
url: "/child/:id",
views : {
'': {
templateUrl: 'tpl.child.html',
},
'title': {
templateUrl: 'tpl.title.html',
controller: 'TitleCtrl',
},
}
})
So, we do have a target for "some other view" title or side bar. Check it here
And we can even place some default implementation there inside of our "non-abstract" parent state.
There is extended plunker with non abstract parent state definition:
.state('parent', {
url: "/parent",
views : {
'': {
templateUrl: 'tpl.parent.html',
},
'title@parent': {
template: 'the parent own TITLE',
},
}
})
Check it here
A: There is a way, how to grant access to latest/up-to-date $stateParams - including current state and its child(ren) as well. (working example here)
It is surprisingly easy:
.run(['$rootScope', '$state', '$stateParams',
function ($rootScope, $state, $stateParams) {
$rootScope.$state = $state;
$rootScope.$stateParams = $stateParams;
}])
And that's it. (check similar answer and some discussion here)
With this approach, we will even in parent $scopes have updated reference to the latest $stateParams. While in our own, we will still receive just our own part
.controller('ParentCtrl', ['$scope', '$stateParams', function ($scope, $stateParams) {
$scope.currentStateParams = $stateParams;
}])
The above is valid for states like these:
.state('parent', {
url: "/parent?area",
templateUrl: 'tpl.html',
controller: 'ParentCtrl',
})
.state('parent.child', {
url: "/child/:id",
templateUrl: 'tpl.html',
controller: 'ChildCtrl',
})
Working example to play here.
But I still would say, that this is a bit ... against the UI-Router. I would prefer this answer. Because in that case, each view (while injected into some parent area) is really aware about $stateParams, which belongs to that state. What we are doing here is introduction of some observer pattern (we should watch changes if we want to react in parent) and that would later bring more issues then profit

The point is that the number of path elements can vary, and their values can refer to different elements of the source document (including using functions).
Is there a way to use the values of some elements as an expression of the search for other?

The server side is a J2EE application extracting the data and blobs entered previously and doing some tests such as face recognition, alphanumeric matching etc. These tests are done asynchronously and continuously.I thaught to use the multithreading for these processes done by the server side.
So is that recommended for such case ? Is there other solution ?
A: There are several limitations in GAE that somewhat limit it's multiprocessing abilities:
*
*Each request can make up to 50 threads, but threads can not outlive the request, which itself has a 60 seconds limit. Also, threads must be created via GAE's own ThreadManager, which limits the use of most external processing libraries.
*Background threads independent of current request are available and can be long-lived, but there is a limit of 10 background threads per instance.
For async processing you should look into Task Queues - it has all above limitations, but can run for 10 minutes. You can start periodic processing via Cron jobs.
Note that GAE instances are quite limited (default is single core 600MHz, 128Mb RAM). They are also quite expensive given how low-power they are. If you need more processing power you should look into Compute Engine (powerful, stand-alone, unmanaged, no GAE-services access, fairly priced for the power), or in your case preferably Managed VMs (powerful, managed, limited GAE-service access, same price as CE).
So if you have light processing, use Task Queues, if you need more power use Managed VMs (currently in preview).

the filter purpose is to insert FEC bits just before the H.264 NAL's header,
what requires me to read the encoder's data on the bit LEVEL.
I already made the FEC filter DLL and connected it using GraphEdit.
Suppose I want to see some LOG msg with the video data(bits) entering my filter in the GraphEdit
anyone knows how to generate those log msgs or log file?
A: there're two possibilities:
1) implement logging of anything you need to know to external file in you FEC filter
2) you can put "smart tee" filter before (and/or after) your FEC filter to "tee" the stream and connect the second pin to "dump" filter (http://msdn.microsoft.com/en-us/library/dd388553(v=vs.85).aspx) that can write all received samples to the file for later analysis
A: OutputDebugString and attaching a debugger will print the messages into the debug window of the IDE.
On the other hand, you can use output logger like DbgView which capture all OutputDebugString messages in the system.
A: Some tools for analyzing data flow between filters:
Open source graph editor GraphStudioNext analyzer filter (and analyzer file writer) will show you a visual log of activity when inserted between two filters of interest. You'll need to build it yourself to get this feature for now.
Geraint Davie's monitor filter will write a log file of activity to disk.

For scenarios and queries posted below, this database is used:
Scenario 1
Am not able to figure out database name? I thought it's restaurants, but with this assumption, below code didn’t work, and getting PERMISSION_DENIED exception:
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if database == "restaurants";
}
}
}
Scenario 2
Collection restaurants have 10 documents, as appearing in above screen, I have hard coded those 10, and allowed them to read and write as below, but its not working, and getting same PERMISSION_DENIED exception:
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read : if document in ['2uFMIc2BSH6oslxEABpB','8GMNVxVUb1HzRAk2QmmX',
'AryyMURod8AeWAfBVavF','AvnpKGMeUWDSfowFLpwa','H0qi7gI8WmSVobu19G49',
'H2xhfoj0Rn75BH9nnbuI','NRfgppqWRfj3DtHDlft4','R9gZ0hTxCPXwSeV2prNV',
'YgXXwndeIfZx6rUhdlc4','v22FlL7LBBY851N8sIvQ'] ;
allow write : if document in ['2uFMIc2BSH6oslxEABpB','8GMNVxVUb1HzRAk2QmmX',
'AryyMURod8AeWAfBVavF','AvnpKGMeUWDSfowFLpwa','H0qi7gI8WmSVobu19G49',
'H2xhfoj0Rn75BH9nnbuI','NRfgppqWRfj3DtHDlft4','R9gZ0hTxCPXwSeV2prNV',
'YgXXwndeIfZx6rUhdlc4','v22FlL7LBBY851N8sIvQ'] ;
}
}
}
These 2 may not be very practical scenarios, but its more for my understanding.
A: *
*In your first example, database is the name of your database, which is probably something like "(default)".
*In your second example, document is going to be the full path of your document; that's what that =** wildcard does -- it's a "everything else in my path" kind of wildcard. So it'll equal something like restaurants/2uFMIc2BSH6oslxEABpB
If you want to create a rule that says, "A user can read any document in my restaurants collection" you want something like this:
service cloud.firestore {
match /databases/{database}/documents {
match /restaurants/{restaurantID} {
allow read, write: if true;
}
}
}
If you want to do something interesting with the document ID of your individual restaurants, you probably want to do something more like this:
service cloud.firestore {
match /databases/{database}/documents {
match /restaurants/{restaurantID} {
allow read, write: if restaurantID == '2uFMIc2BSH6oslxEABpB; ;
}
}
}

*Lauch both the Game and the Task.
*Start a game of the Game and immediately pause it.
*Alt tab to the task.
*Do it until a point determined in the program. At which point I am
told to switch to the game.
*Alt tab to the game
*Unpause it and start a clockwatch.
*When the clockwatch reaches X minutes (X determined in advance),
pause the game.
*Alt tab to the task.
*Repeat steps 4-7 N number of times.
I have no idea whether it is possible or what tools to use. I understood that a simple bash file won't be enough and I might need to use a "fake keyboard" program to force some inputs (such as "space bar" to pause the game). But I have no idea how to coordinate all of that.
Thanks in advance for any help. Even telling me it's not possible is an acceptable answer :)
EDIT : Edited the list for clarity
A: From what information you have given, it is difficult to tell whether the complete process can be automated, but there are tools like AutoHotKey which you can use to write scripts to automate desktop applications.
A simple script in autohotkey to start a program "Notepad", another program "Calculater", and switch back to "Notepad" and write "Hello World!" in it.
SetTitleMatchMode, 2
Run "C:\Windows:\Notepad.exe"
Run "calc.exe"
WinActivate, Notepad
Send, Hello World!
The above is a very simple script. It does not activate the specific notepad window you want if multiple notepad windows are open. However, that can be automated too.

A: There are several things wrong with the approach you currently have, as I and others have commented, Brent Ozar has a good reference on dynamic SQL https://www.brentozar.com/sql/dynamic/
I would say don't pass in some SQL, construct it in the stored proc; passing in parameters such as name which is used in the where, hence I have put a full working example. This also shows how to pass the user defined table type into the stored proc and then also pass it into the dynamic SQL.
I hope this is a good enough example of the techniques, I had a bit of time so thought I would try and help as much as possible :)

Its also worth noting that if you can just join on the @Values without needing dynamic SQL then that is sure to be less work.

Here is an example. I have a simple dataframe
library(tidyverse)
set.seed(123)
df <- data.frame(time = seq(1,5,1),
x = seq(1,5,1) + rnorm(n=5, sd=0.3))
> df
time x
1 1 0.8318573
2 2 1.9309468
3 3 3.4676125
4 4 4.0211525
5 5 5.0387863
I would like to add the time at which x exceeds a particular value (e.g., x > 4) to a new column, named border_value.
The following code does works:
df <- df %>% mutate(border_value = min(.[.$x > 4, "time"]))
> df
time x border_value
1 1 0.8318573 4
2 2 1.9309468 4
3 3 3.4676125 4
4 4 4.0211525 4
5 5 5.0387863 4
Question
I have a lot of dataframes, in which the values for x differ. Sometimes, the values do not exceed the border_value of x>4. In those cases, R generates an error:
Warning message: In min(.[.$x > 4, "time"]) : no non-missing arguments
to min; returning Inf
I would like to alter my code so that this error does not occur, and R puts NA's in the column instead. Any idea how to do this?
Update
Based on this post, I was able to rewrite the code to:
df <- df %>%
mutate(border_value = ifelse(test = is.infinite(min(.[.$x > 7, "time"])), yes = NA, no = min(.[.$x > 4, "time"])))
This doesn't generate the Infs, but still generates the error...
A: There are many ways you can write that. Here are a couple based on your use case,
df %>% mutate(border_value = which(x > 4)[1])
df %>% mutate(border_value = time[x > 4][1])
Both will return NA if no value is found

However, with jquery's .hide() applied to the last child, the element is just given display:none, therefore making the visually last element still showing its border-bottom.
What's the best way to solve this, that is also reusable across other similar ul within the project?
A: If you want to remove border-bottom of last 'li' element, then use following CSS:-
.classname:last-child{
border-bottom:0;
}
Where classname is the class added to the 'li' element.
.hide() will hide the last 'li' element, not border.

For example, in portrait mode, I have 2 UIImageViews on top and bottom that share the screen evenly. In landscape mode, the 2 UIImageViews are side by side. How can this be done using storyboard in Xcode 6?
Things I have tried:
*
*Settings constraints on the views in storyboard with size classes. I
set the base values for my 2 imageviews in w:Any h:Any, then moved
to w:Compact h:Regular and set constraints for portrait view.Then
I moved to w:Any h:Compact, moved the 2 imageviews side by side
and set constraints for landscape view. Then I get conflicts in
w:Compact h:Compact because of the constraints I have applied for
and landscape and portrait orientation. I think it's because I moved
the image views around for landscape orientation before settings the
constraints that caused this problem.
*Using 2 separate view controllers and have portrait view controller
switch to landscape view controller when orientation changes using
NSNotificationCenter and performSegueWithIdentifier to push the
landscape view controller on top of my portrait view controller.
This problem is that there's lots of data to be passed(lot of
imageviews and labels).
Is the a way to use only one view controller and a way to rearrange the imageviews/labels and apply new constraints on them when the orientation changes? Is -(void)viewDidLayoutSubviews{} where I put the code to rearrange the image views? Can someone point me in the right directions? Thanks!
A: For this case I recommend to make layout programmatically via code.
Here is example:
https://dl.dropboxusercontent.com/u/48223929/Test.zip
- (void)viewDidLayoutSubviews
{
[super viewDidLayoutSubviews];
[self layoutImageViewsForViewSize:self.view.frame.size];
}
- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{
[self layoutImageViewsForViewSize:size];
}
- (void)layoutImageViewsForViewSize:(CGSize)size
{
// Portrait mode
if (size.height > size.width) {
self.imageView1.frame = CGRectMake(0, 0, size.width, size.height / 2);
self.imageView2.frame = CGRectMake(0, size.height / 2, size.width, size.height / 2);
// Landscape mode
} else {
self.imageView1.frame = CGRectMake(0, 0, size.width / 2, size.height);
self.imageView2.frame = CGRectMake(size.width / 2, 0, size.width / 2, size.height);
}
}
For autolayout:
- (void)layoutImageViewsForViewSize:(CGSize)size
{

Another solution for autolayout - make your custom subclass of UIView, which contains 2 image views, and layout it programmly without constraints - just setFrame.
And then add this custom UIView to your storyboard

using this date and time automatically saving PostgreSQL db in format of 2020-01-24 20:13:47.846445+05:30 with offset(+05:30) but i want to save it as
2020-01-24 14:43:47.846445+00:00 without offset means as 00 but if inspect one instance created_at row data using
python manage.py shell i am getting required format(Django handling internally fine) so how to save date and time with offset 00:00 ?
what is tried is using manually assigned timezone.now()(its value is 2020-01-24 14:43:47.846445+00:00) to updated_at but if i open PostgreSQL editor again showing same value as 2020-01-24 20:13:47.846445+05:30 instead of 2020-01-24 14:43:47.846445+00:00
all of the above in local laptop but tried another way i hosted my django in production server with ip location(sever cloud server location) is india now my db showing correct result as 2020-01-24 14:43:47.846445+00:00 with offset 00 i dont know how

I usully do this
agent=Mechanize.New
page=agent.get("www.some_url.com/atributes")
but insted of that I want to test if a page is attributed to that url before downloading it
A: The only way to see if a page exists (and that you can reach it via the internet) is to perform an actual request. You could first do a HTTP HEAD request, which only requests the headers, not the actual content:
url = "www.some_url.com/atributes"
agent = Mechanize.New
begin
agent.head(url)
page_exists = true
rescue SocketError
page_exists = false
end
if page_exists
page = agent.get(url)
# do something with page ...
end
But then again, you can just get rid of the extra request and rescue from errors directly with the GET request:
url = "www.some_url.com/atributes"
agent = Mechanize.New
begin
page = agent.get(url)
# do something with page ...
rescue SocketError
puts "There is no such page."
end

} catch (IOException e) {

}
}
}
}
The problem as I stated before is that when i run my application , the video gets uploaded and the image gets generated that time, but next time when i upload videos, only the video gets uploaded not the images. I have to restart Tomcat to achieve the same again, so please help. Thanks in advance and sorry for making this a long topic.
A: Try removing the static keyword for these two variables in the Main class:
private static long mVideoStreamIndex = SECONDS_BETWEEN_FRAMES;
private static long mLastPtsWrite = Global.DEFAULT_PTS_PER_SECOND + SECONDS_BETWEEN_FRAMES;
If you make them static their value will be kept across calls and I doubt this is really what you want. Correct me if I'm wrong.

I have a docker-compose file in which all µ-services will be manual created.
Now I have a problem.
If I use discovery with akka-dns their is nothing found.
If I use static and give them the exposed ports their is also not found. Where is my mistake?
Docker compose file:

}
For other domains on the same server i have a reverse nginx. But not for this project.
When I run http://SERVER-IP:14999 in browser I get a 404 NotFound typical Play screen message. :(
I have no problem to write the compose file and to link them manual. I have also no problem to use akka-dns. But I will have no kubernetes or something else.
Thanks for you help

It looks like the startup process is completly going wrong.
Inside of the securityapplication class it should be generated a user with this code
val newUUID = UUID.randomUUID()
clusterSharding.entityRefFor(Profile.typedKey,newUUID.toString).ask[ProfileConfirmation](reply => CreateProfile(username,password,Some(EmailAddress(username)),Set(SuperAdminRole), PersonalData("","",""),reply ))(30.seconds).map{
case ProfileCmdAccepted(profile) => s"Profile ${profile.login} created"
case ProfileCmdRejected(err) => s"ERROR while default user init: $err"
case a => s"a: $a"
}
But there is throwing a Timeout exception. I think the cluster service is not initialized. At demo all working.
Do someone has an idea?
A: Okay found it
in the production conf I added
lagom.services {
security-service = "http://"${REMOTE_IP}":15000"
binary-service = "http://"${REMOTE_IP}":15001"
}
lagom.cluster.bootstrap.enabled = false
In the lagom Application loader in method load I inheriated my application from
ConfigurationServiceLocatorComponents
And now really important!
The docker must configured!
I used docker compose.
First adding a netowrk!
networks:
panakeia-network:
# driver: bridge
ipam:
driver: default
config:
- subnet: 172.28.0.0/16
AND now I give the cluster.seed-nodes.0 the ip of the service! And name the system! That is also important!
security:
container_name: panakeia-security
image: security-impl:latest
environment:
- APPLICATION_SECRET=****
- POSTGRESQL_URL=jdbc:postgresql://postgres-database:5432/panakeia
- POSTGRESQL_USERNAME=????
- POSTGRESQL_PASSWORD=******
- INIT_USERNAME=test@test.de
- INIT_USERPASS=*******
- JWK_KEY=******
- REQUIRED_CONTACT_POINT_NR=1
- KAFKA_BROKER=REALLY_IP/OR_KAFKA_SERVICE_NAME:9092
- REMOTE_IP=????
- JAVA_OPTS=-Dconfig.resource=prod-application.conf -Dplay.server.pidfile.path=/dev/null -Dakka.cluster.seed-nodes.0=akka://panakeia@172.28.1.5:25520 -Dplay.akka.actor-system=panakeia
expose:
- 9000
- 15000
ports:
- "15000:15000"
- "14999:9000"
networks:
panakeia-network:
ipv4_address: 172.28.1.5
With this way it looks like it possible to create a simple and small µ-services cluster without complex systems like kubernetes.

for(int i = 100000; i > 0; i--) {}
for(int i = 1; i < 100001; i++) {}
A: This is because in bytecode comparison with 0 is a different operation than comparison with a non-zero number. Actually i < 10001 requires to first load the number on stack then execute comparison, while i > 0 is executed as one operation. Of course there will be no speed difference in most cases because of JVM optimizations. But we can try to make it visible by running the code with -Xint option (interpreted mode execution only).
A: Piyush Bhardwaj
I tested both the loops in online compiler but my increment loop is executing faster then decrement loop.
Program execution depends upon many factors. When sometimes we run the same program on same machine many times we gets different execution times. So it depends upon many factors.
See the results
for(int i = 1; i < 100001; i++) {
}
Increment loop -- http://ideone.com/irdY0e
for(int i = 100000; i > 0; i--) {
}
Decrement loop -- http://ideone.com/yDO9Jf
Sir Evgeniy Dorofeev has given an excellent explanation which an expert only can give.
Finally, you need to consider the performance of your CPU. When considering a benchmark to determine the overall performance of a Java application, bear in mind that bytecode execution, native code execution, and graphics each play a role. Their impact varies depending on the nature of the specific application.

use Closure;
use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;
class VerifyCsrfToken extends BaseVerifier {
public function handle($request, Closure $next)
{
return parent::handle($request, $next);
}
}
Javascript:
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': 'wrong-token-to-test',
'X-XSRF-TOKEN': 'another-wrong-token-to-test',
}
});
Blade:
$.ajax({
method: "POST",
url: "{{url("login/$user")}}",
data: {
"email": $("#email").val(),
"password": CryptoJS.SHA256($('#password').val()).toString(),
"_token": "{{csrf_token()}}"
}
})
Even using the wrong Http header value ('wrong-token-to-test') for csrf token does not result in any token mismatching exception. The request is handled normally. Does that mean Laravel is not checking for the X-CSRF-TOKEN header?
A: Laravel first tries to get the CSRF token from the parameter called _token in the get or post, and if missing, THEN it tries to get it from a X-CSRF-TOKEN. Here is the implementation logic in the code in /vendor/laravel/framework/src/Illuminate/Foundation/Http/Middleware/VerifyCsrfToken, method tokensMatch :
$token = $request->input('_token') ?: $request->header('X-CSRF-TOKEN');
But you are already effectively including the _token parameter (and with correct value) in your ajax post:
"_token": "{{csrf_token()}}"
So it doesn't matter what you send in the X-CSRF-TOKEN header.

SOCKET ListenSocket;
struct sockaddr_in saServer;
// Bind the listening socket using the information in the sockaddr structure
bind( ListenSocket,(SOCKADDR*) &saServer, sizeof(saServer) );
Here are the declarations for the two structs. This is technically undefined behavior, correct?
struct sockaddr {
ushort sa_family;
char sa_data[14];
};
struct sockaddr_in {
short sin_family;
u_short sin_port;
struct in_addr sin_addr;
char sin_zero[8];
};
A: Between the dawn of C (going back at least to 1974) and 1989, if two structures shared a Common Initial Sequence, the language unambiguously allowed code to use a pointer of one structure type to inspect CIS members of the other. In the C99 standard, that permission was restricted to cases where both structure types are part of a union type whose complete declaration was visible at the point where the CIS value is inspected; some people insist that because the authors of the 1989 meant to impose such a restriction it applies to C89 as well. In addition, some compiler writers insist that because the authors of the Standard only meant for that guarantee to apply to accesses made through lvalues of union type, they'll ignore the part of the Standard that says that a definition of a "complete union type" must be visible.
Implementations are allowed to provide guarantees beyond those required by the Standard. Because non-psychic people writing code prior to C99 had no reason to expect that they would need to include otherwise-unnecessary union declarations in order to exploit the CIS guarantees, and because a lot of code written from that era relies upon those guarantees despite a lack of such declarations, anyone wanting to write an implementation suitable for use with such code must support them whether or not the Standard requires such support. While there is no particularly good reason why updates to the header file shouldn't include a union type declaration, I'm not sure how many compilers would care about its presence or absence. The compilers I've seen either support the CIS guarantees even without a complete union type declaration visible, or dishonor the CIS guarantees (ignoring the Standard) even when the declaration is present.

And this is a screenshot of what I had
But this is what I need my Layout to be with all Devices. Maybe I should use weights, but I don`t know how
A: Check this Sudoku project -
Git Hub
Also
Check This
Here you can find layout and source code for Sudoku and also other useful things.
A: Here's a trick: For a completely uniform table or grid, you don't need TableView or GridView at all. Just put everything inside LinearLayout with size=0 and layoutWeight=1. That size=0 seems counter-intuitive, but combined with the layoutWeight=1, it has the effect of giving all child widgets the exact same size, regardless of their contents.
So do something like this:
<!-- Outer container; a vertical layout that fills the screen -->
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<!-- first row -->
<LinearLayout

I need to open Dialog for button click.
When button 1 clicked some text appears and when button2 clicked something other text appears as dialog.
My code
btn1.setOnClickListener{ showCustomDialog() }
btn2.setOnClickListener{ showCustomDialog() }
private lateinit var alertDialog: AlertDialog
fun showCustomDialog() {
val inflater: LayoutInflater = this.getLayoutInflater()
val dialogView: View = inflater.inflate(R.layout.dialog_custom_view, null)
val headerbtn = dialogView.findViewById<TextView>(R.id.header)
headerbtn.text = "Header Message"
val dialogBuilder: AlertDialog.Builder = AlertDialog.Builder(context!!)
dialogBuilder.setOnDismissListener(object : DialogInterface.OnDismissListener {
override fun onDismiss(arg0: DialogInterface) {
}
})
dialogBuilder.setView(dialogView)
alertDialog = dialogBuilder.create();
alertDialog.window!!.getAttributes().windowAnimations = R.style.PauseDialogAnimation
alertDialog.show()
}
A: Send the String to the Function then put it on TextView.
btn1.setOnClickListener{ showCustomDialog("This is Text 1") }
btn2.setOnClickListener{ showCustomDialog("This is Text 2") }
Function :
fun showCustomDialog(data: String) {
val inflater: LayoutInflater = this.getLayoutInflater()
val dialogView: View = inflater.inflate(R.layout.dialog_custom_view, null)
val headerbtn = dialogView.findViewById<TextView>(R.id.header)
headerbtn.text = data
val dialogBuilder: AlertDialog.Builder = AlertDialog.Builder(context!!)
dialogBuilder.setOnDismissListener(object : DialogInterface.OnDismissListener {
override fun onDismiss(arg0: DialogInterface) {
}
})
dialogBuilder.setView(dialogView)
alertDialog = dialogBuilder.create();
alertDialog.window!!.getAttributes().windowAnimations = R.style.PauseDialogAnimation
alertDialog.show()
}

<TextView android:text="@string/hello_world" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
So , when i click on the button present inside activity_main.xml
the background set to the second activity didn't get dispalyed.
A: If you want to open activity_display_message from your activity_main, you need to use startActivity(intent) on button click.
yourButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick() {
Intent intent = new Intent(MainActivity.this, DisplayMessageActivity.class);
startActivity(intent);
}
})
A: What exactly are you trying to ask?
Do you want to replace the first activity with second? Or add the second activity as a component to the first activity? If yes , then you should just inflate the second activity[component] in the first activity dynamically, as follows:
Inflate second activity->add to->First activity's linear layout/or whichever layout

In a charting object, defined with namespace:
xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit"
I am drawing a simple bar chart.
<charting:Chart Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3"
Visibility="{Binding Path=MyCurrentResultsView, Converter={StaticResource ResourceKey=NullObjectToVisibilityConverter}}"
Background="Transparent" Foreground="White"
Margin="50,0,50,0" Height="350"
HorizontalAlignment="Stretch" Title="{Binding Path=MyCurrentResultsView.Name}">
<charting:ColumnSeries Height="350" Foreground="Black"
ItemsSource="{Binding Path=MyCurrentResultsView.ResultsView}"
IndependentValueBinding="{Binding Key}"
DependentValueBinding="{Binding Value}">
</charting:ColumnSeries>
</charting:Chart>
What I'd like to do is to show the value of each column above the column (or even inside the column rectangle if possible: these are percentage values and the idea is to make them more visible on the bar chart).
I have been looking at the styling information, but here this is more than just style. I see two possibilities. Either:
*
*For each column item in the series, define a transformation that positions a frame above each column, creates a text box whose label is set to the dependent value, then draws the text box inside the frame.
*Find some kind of property on "ColumnSeries" or "? ColumnItem ?" that "enables" the display of the bound value above the column.
Total shot in the dark here. Thanks.
A: I would try to change the ColumnDatapointTemplate like this:
<charting:ColumnSeries Height="350" Foreground="Black"
ItemsSource="{Binding Path=MyCurrentResultsView.ResultsView}"
IndependentValueBinding="{Binding Key}"
DependentValueBinding="{Binding Value}">
<charting:ColumnSeries.DataPointStyle>
<Style TargetType="charting:ColumnDataPoint">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="charting:ColumnDataPoint">
<Grid>
<Rectangle Fill="{TemplateBinding Background}" Stroke="Black"/>
<Grid Margin="0 -20 0 0" HorizontalAlignment="Center" VerticalAlignment="Top">
<TextBlock Text="{TemplateBinding FormattedDependentValue}" Margin="2"/>
</Grid>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</charting:ColumnSeries.DataPointStyle>
</charting:ColumnSeries>
Play a bit with vertical alignments and/or margins and you will be able to get infos into the columns and other.
Hope this help!

(setq-default c-basic-offset 4 c-default-style "linux")
(setq-default tab-width 4 indent-tabs-mode t)
(define-key c-mode-base-map (kbd "RET") 'newline-and-indent)
I'm getting a warning when I open up emacs:
Warning (initialization): An error occurred while loading
c:/home/.emacs:
Symbol's value as variable is void: c-mode-base-map
To ensure normal operations, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with the
--debug-init option to view a complete error backtrace.
I ran --debug-init and this is what it returned. I don't know what I means:
Debugger entered--Lisp error: (void-variable c-mode-base-map)
(define-key c-mode-base-map (kbd "RET") (quote newline-and-indent))
eval-buffer(#<buffer *load*> nil "c:/home/.emacs" nil t)
; Reading at buffer position 311
load-with-code-conversion("c:/home/.emacs" "c:/home/.emacs" t t)
load("~/.emacs" t t)
A: What this means is that, at the point at which you invoke define-key, c-mode-base-map is not yet defined by anything.
The usual fix is to find out where this is defined and require that module. In this case:
(require 'cc-mode)
However there are other possible fixes as well, for example setting the key-binding in a mode hook, or using eval-after-load. Which one you use is up to you; I tend to do the KISS approach since I don't generally care about startup time; but if you do you may want something lazier.

WHERE
(dbo.Quiz.QuizID = @QuizID)
GROUP BY
dbo.Divisions.DivisionShortcut
This SqlDataSource lets the user enter the number of the Quiz, and it will retrieve the total number of participants in that quiz. I want to convert this SqlDataSource to a DataTable and read a column from it.
So how to do that?
A: The SqlDataSource has a Select method which you can call to get back a DataView from your SqlDataSource - see the MSDN documentation on that.
SqlDataSource dataSource = new SqlDataSource(connectionString, selectSql);
DataView view = (DataView)dataSource.Select(args);
DataTable table = view.ToTable();
Is that what you're looking for??
A: Let me say you have an SqlDataSource named as SqlDataSource1
DataSourceSelectArguments args = new DataSourceSelectArguments();
DataView view = (DataView)SqlDataSource1.Select(args);
DataTable dt = view.ToTable();
Now you can read a column easily from this dt(DataTable) e.g.
int columnNumber = 0;
for(int i=0;i<dt.Rows.Count;i++)
{
MessageBox.Show(dt.Rows[i][columnNumber].ToString());
}

Does this only affect new customers, or will users who have downloaded the app while it was still available be able to redownload it from their "past purchases" section in the App Store or iTunes?
I know that this has been asked in the past, but those answers either predate or do not mention the "past purchases" feature of the App Store.
(For example, I am still able to download a certain bird-themed jumping game from that section, even though it is no longer listed in the store; however, in that case, the app has probably only been depublished even though the associated developer account is still available.)
A: Apple documents about expired membership -
Expired Memberships If your Apple Developer Program membership
expires, your apps will no longer be available for download and you
will not be able to submit new apps or updates. You will lose access
to pre-release software, Certificates, Identifiers & Profiles, and
Technical Support Incidents. However, your apps will still function
for users who have already installed or downloaded them, and you will
still have access to iTunes Connect and free development resources.
If your Apple Developer Enterprise Program membership expires, your
apps will no longer be available for download and will no longer
function for those who have already installed or downloaded them. You
will still have access to free development resources.
This means If your developer account expired then yours app not available for download for both new and old user.But still app will be functional if user already install or downloaded into their device. In this case In App purchase will be work. But He/She if delete the app then he/she can't download further this app until developer account renew.
A: After seeing your question I decided to test this for myself. I was able to locate Tap Tap Revenge 3 in my purchase history, download it, and install it on my iPhone 5c running iOS 8.3. The game doesn't function anymore as the game servers have shut down, but it was able to run beyond the launch image at least, which suggests that the app can indeed run provided it doesn't have compatibility issues or depend on any servers that have been taken offline.
Tapulous shut down in January 2014 and I don't expect their developer account to still be active today. According to the linked article, IAPs cannot be restored, so there is that. I can confirm that the app itself is still available for download in my purchase history, however.

e.g.: Access {$host}/hello/word
I expect yii load in mobile path:
application.controller.mobile.HelloController
So I add this in config file, but it not work.
'import'=>array(
'application.models.*',
'application.components.*',
'application.controllers.mobile.*',
),
Actual yii always load the application.controller.HelloController, It's not found.
I have muilt site (web2.0, mobile) in one application so only to do this for namespace
A: I haven't checked out this myself but I think you should try this:
'import'=>array(
'application.models.*',
'application.components.*',
'application.controllers.*',
'application.controllers.mobile.*',
),
You might have to include controllers directory before including any other classes (controllers) inside of it.
A: 1. If mobile is a directory inside controllers directory where you have saved all the controllers files then try this
'application.controllers.mobile.*',
2. If mobile is a controller file inside the controllers directory then
'application.controllers.MobileController',
3. If you want to access only the HelloController which is inside mobile directory which is further inside controllers directory then
'application.controllers.mobile.HelloController',
4. If HelloController is inside controllers directory then
'application.controllers.HelloController',

So I create a control and provide its handle.
Then, when I check the native window using Spy++, I see that my control is wrapped in additional 'control' with window class = "Static" and title "This is a static!". I have several problems with it:
*
*Resize events sent to my control by a hosting window have to be re-sent to the "Static" so it also gets resized (otherwise my control get partially hidden within the static's size).
*The static does not have WS_EX_CONTROLPARENT, which causes KB149501 to appear (in short, whole application hangs on lost focus).
*If I apply WS_EX_CONTROLPARENT, listbox within the static stops redrawing.
I think I have been doing something wrong, but I am not sure what. Google does not help, since static is a C# keyword as well so it occurs quite often in WinForms results.
A: I mostly solved the redrawing problem using DoubleBuffered=True, so probably this is it.
I still think I am doing something wrong, but at least it works now.

YAML::dump s # ArgumentError: invalid date
YAML::ENGINE.yamler = 'syck' # => "syck"
YAML::dump s # => "--- \"2222-33-44\"\n"
A: I have found that it is a known bug. It has been fixed but looks like the version in RubyGems is not containing the fix.
Also as the git repository doesn't have a proper .gemspec is not easy way to install from the repo.
You can fork the repo and add a proper .gemspec and use a Gemfile that points to your fork repo.
Also you can ask kindly to Aaron to release the fix.

How can I, using multisite, limit a function to only given site? I use such function to adapt homepage regarding user state:
function switch_homepage() {
if ( is_user_logged_in() ) {
$page = 4284; // for logged in users
update_option( 'page_on_front', $page );
update_option( 'show_on_front', 'page' );
} else {
$page = 4133; // for logged out users
update_option( 'page_on_front', $page );
update_option( 'show_on_front', 'page' );
}
}
I want the code to just work on a main site. Thanks for you help!
A: You can test if the current site is the main site with this code:
if ( is_main_site() ) {
// Do stuff only for the main site
}
Another option is to add your code in a plugin and then activate the plugin only on the main site.

To add a link to the search results when no direct match is found.
Detail:
I want to add a link to the search results when no direct match is found. My thought was to try and detect a direct match then add the link to the results, assuming its not already there.
A good example of this is Github's milestone search on an issue. If you search for a milestone that doesn't exist a link is presented to create one instead.
Flow:
*
*User inputs text
*
*If a direct match IS found - no link displayed
*If NO direct match found - display link to create object
I'm just not sure how or if I can detect a direct match and then add a datum. Any help on how to implement this or if it's possible would be appreciated?

public class RunSecondApp {
public Response runAppB(ApplicationBAdapter applicationBAdapter){
return applicationBAdapter.run(request);
}
Inside App B there are many invocations to current date (in Blaze Advisor it's CurrentLocalDate method - I think it's compiling to Java's LocalDate method but I'm not sure). Now what I need is to somehow mock the current date so that this invocations to current date in App B would return not today's date but a substitute.
Changing the system date is not an option.
I've read about PowerMock, JMockito, Expectations.class but every time I try this it's failing. Did anyone try something similar to this?

{% for obj in objects %}
{% if forloop.first or forloop.counter0|divisibleby:4 %}
<div class="row" >
{% endif %}

["Monday: 8:00 AM \u2013 7:00 PM","Tuesday: 8:00 AM \u2013 7:00 PM","Wednesday: 8:00 AM \u2013 2:30 PM","Thursday: 8:00 AM \u2013 7:00 PM","Friday: 8:00 AM \u2013 7:30 PM","Saturday: 8:00 AM \u2013 6:00 PM","Sunday: Closed"]
What am I missing here?
A: You are seeing unicode escape sequences because of how toString is implemented. It is implemented this way probably to make it clear which characters are in the string, which makes it easier to debug your code, because sometimes different code points can look very similar.
The actual strings are still unescaped. Printing individual strings in the array will not show escape sequences:
System.out.println(resultJSON.getJSONObject("result").getJSONObject("opening_hours").getJSONArray("weekday_text").getString(0));
A: You can use a OutputStreamWriter to manage the output encoding.
JSONObject resultJSON = new JSONObject(result);
ByteArrayOutputStream out = new ByteArrayOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(out, "utf-8");
resultJSON.write(writer);
writer.flush();
String jSONStringUTF8 = new String(out.toByteArray(),"utf-8");
JSONObject newJSON = new JSONObject(jSONStringUTF8);
String value = newJSON.getString("content");

I'm wondering how to fix this annoying issue so they always stay in position regardless of screen size??
I have this as my CSS:
.wrapper{
margin:0 auto;
width: 80%;
display: table-cell;
}
.gridf{
float:left;
margin-right:3px;
width:200px;
min-height:200px;
border:1px solid white;
}
.grid{
float:left;
margin-left: 3px;
margin-right:3px;
width:200px;
min-height:200px;
border:1px solid white;
}
.gridl{
float:left;
margin-left: 3px;
width:200px;
min-height:200px;
border:1px solid white;
}
My HTML:
<div style="overflow: hidden;">
<div class="wrapper">
<div class="gridf"></div>
<div class="grid"></div>
<div class="grid"></div>
<div class="gridl"></div>
</div>
</div>
Please help :D
A: Your wrapper is a percentage width container with 4 fixed-width child elements floated.
The width of the wrapper is dependent on the width of the viewport. If the viewport is narrowed to the point that the wrapper's width is less than that of the 4 child element widths together, then naturally they won't all fit and therefore will wrap.
The fix is to make sure your wrapper doesn't get smaller than the combination of the children.
So, add up with widths, borders and margins of the child elements and then give the wrapper a min-width attribute equal to that.
A: Hi i think you should this check to this demo
.wrapper {
margin: 0 auto;
width: 80%;
border: solid 1px red;
overflow: hidden;
}
.gridf,
.grid,
.gridl {
Background: green;
width: 24%;
min-height: 100px;
float: left;
margin: 2px 0;
}
.gridf {} .grid {
margin: 2px 1%;
}
.gridl {
background: yellow;
}
<div class="wrapper">
<div class="gridf">One</div>
<div class="grid">Two</div>
<div class="grid">Three</div>
<div class="gridl">Four</div>
</div>
A: Although this is an old post, I think that the problem, which I also run into, is the fact that you want all these cells to be of a fixed size, and not %, right? The solution you chose changed initial format where you specified width:200px;
Well, I would suggest to look here: http://jsfiddle.net/gn2bg/
The ONLY one thing I did is to add inner wrapper around your cells:
.inwrapper{
float:left;
overflow: hidden;
min-width: 830px;
}
and new html as this:
<div class="wrapper">
<div class="inwrapper">
<div class="gridf"></div>
<div class="grid"></div>
<div class="grid"></div>
<div class="gridl"></div>
</div>
</div>
Notice that your wrapper requires 80% of space.
The inwrapper, however, tells that its size is fixed - 830px (total of all internal div sizes plus room for padding.)
This way inwrapper uses 'elbows' to stretch the width, and override these 80% of 'wrapper'
I understand that you already made decision as to what is your best solution. I am leaving this response to anyone else in the future who needs exact answer to your exact question.
A: You can try removing the table-cell display rule from the wrapper and setting percentages (or min-widths) on the child divs like this jsFiddle example.
A: That should do the trick :
<div class="wrapper">
<div style="width:850px">
<div class="gridf"></div>
<div class="grid"></div>
<div class="grid"></div>
<div class="gridl"></div>
</div>
</div>
And that will be supported on any browser.
http://jsfiddle.net/5GrKU/3/
A: HTML
<div style="overflow: hidden;">
<div class="wrapper">
<div class="gridf"></div>
<div class="grid"></div>
<div class="grid"></div>
<div class="gridl"></div>
</div>
</div>
CSS
.wrapper{
margin:0 auto;
width: 80%;
display: inline;
}
.gridf{
float:left;
margin-right:3px;
width:20%;
min-height:200px;
border:1px solid red;
}
.grid{
float:left;
margin-left: 3px;
margin-right:3px;
width:20%;
min-height:200px;
border:1px solid red;
}
.gridl{
float:left;
margin-left: 3px;
width:20%;
min-height:200px;
border:1px solid red;
}
for you reference i have also added the URL of the demo. http://jsfiddle.net/sg8FE/
UPDATE
just change display:inline in wrapper class to display:block rest all is right and the div's are centered.
A: by giving a fixed width in your inner divs you are forcing them to have that width no matter what is the size of the view port. And giving the outer div a width of 80% you are shrinking its size with the width of your view port. You need to do either giving fixed width to all those divs or giving a relative width to all.

I have a column of ID that the format is like "C_1_1", "C_1_11", "C_12_11".
The criteria was using the string before the first '' symbol and string after second '' symbol to find matching ID like head and tail e.g. "C_20_2" <-- "C_" and "2". In VBA I tried to use Filter function to filter data that match "C" then 2nd filter that match "_2"
However, the problem I am facing is that because the middle part of the ID is also in a format of "_xx" so there will be unwanted data like in the picture below that all the non-highlighted data is not relevant. Is there any suggestion I can filter or extract only the data in yellow colour? Any suggestion would be appreciated. Thank you so much.
A: Filter Data
Excel
If you have Microsoft 365, without too much thinking, in cell G2 you could simply use:
=FILTER(FILTER(A2:A100,LEFT(A2:A100,LEN(H2))=TEXT(H2,"@")),RIGHT(FILTER(A2:A100,LEFT(A2:A100,LEN(H2))=TEXT(H2,"@")),LEN(H3))=TEXT(H3,"@"))
VBA
Sub FilterData()
Dim wb As Workbook: Set wb = ThisWorkbook ' workbook containing this code
Dim ws As Worksheet: Set ws = wb.Sheets("Data")
Dim sStr As String: sStr = CStr(ws.Range("H2").Value)
Dim eStr As String: eStr = CStr(ws.Range("H3").Value)
Dim rg As Range
Set rg = ws.Range("A2", ws.Cells(ws.Rows.Count, "A").End(xlUp))
Dim Data(): Data = rg.Value
Dim sr As Long, dr As Long, cString As String
For sr = 1 To UBound(Data, 1)
cString = CStr(Data(sr, 1))
If cString Like sStr & "*" & eStr Then
dr = dr + 1
Data(dr, 1) = cString
End If
Next sr
With rg.EntireRow.Columns("G")
.Resize(dr).Value = Data
.Resize(ws.Rows.Count - .Row - dr + 1).Offset(dr).ClearContents
End With
End Sub

This question has been asked multiple times before for standard SQL Server:
*
*How can I clear the SQL Server query cache?
Answer: DBCC DROPCLEANBUFFERS;
*How to let SQL Server know not to use Cache in Queries? Answer: DBCC FREEPROCCACHE;
Or there's always the WITH RECOMPILE option.
However, none of these options appear to have support in the SQL CE world.
I am accessing the database via a C# application, using the SqlCeCommand class, so I am looking for either a code hack or an SQL command to clear the execution plan cache from the database between calls.
A: There is no execution plan cache between calls, but the first access to the database will load the database file, and the engine dll files into memory from disk, and this is costly.

A: Just thought I'd add a comment for the benefit of those who stumble across this for the same reason I did. If your template uses conditional rendering, and those conditions are satisfied asynchronously, the router-outlet cannot be inside the conditional markup because the framework might try to render the markup before the condition is satisfied. For example:
<div *ngIf="someAsyncCall()">
<header>{{some result from the async call}}</header>
<router-outlet></router-outlet>
</div>
may fail depending on how quickly the async call finishes. It's always safer to include only the static parts of a the markup in the conditional rendering. As in:
<div *ngIf="someAsyncCall()">
<header>{{some result from the async call}}</header>
</div>
<router-outlet></router-outlet>
I got bit by wrapping the entire page in a "busy indicator" directive which pretty much guaranteed that the router-outlet would not be available all the time. Seems obvious in hindsight, but....
A: As this article (https://angular-2-training-book.rangle.io/handout/routing/child_routes.html) states when dealing with child routes, just as you define a router-outlet for the root of your application, you must define a router-outlet for your parent component (in this case the ConcursoItemComponent. And technically also the CargoItemComponent & DisciplinaItemComponent) So you have 2 options.
*
*Define a router-outlet in the ConcursoItemComponent. This way the router will know where to load the child component (CargoItemComponent) when the user visits c/:concurso/:cargo
*Don't use child routes and instead make all of your routes at the top router level (root of the application)
{
path: 'c/:concurso,
component: ConcursoItemComponent
},
{
path: 'c/:concurso/:cargo,
component: CargoComponent
},
{
path: 'c/:concurso/:cargo/:disc,
component: DisciplinaItemComponent
},
{
path: 'c/:concurso/:cargo/:disc/:assunto,
component: AssuntoItemComponent
}
This way the router will always insert the component into the router-outlet at the root of the application.
A: If anyone interested in going with Child route structure. You could follow this model. I found this in ngx-breadcrumbs.
const myRoutes : Route[] = {
{
path: '',
component: HomeComponent
},
{
path: 'about',
component: AboutComponent
},
{
path: 'person',
children: [
{
path: '',
component: PersonListComponent
},
{
path: ':id',
component: PersonDetailComponent
}
]
},
{
path: 'folder',
children: [
{
path: '',
component: FolderComponent
},
{
path: ':id',
component: FolderComponent
}
]
}
};

So my cython function signature is as follows:
cpdef cnmi_gradient_2d(double[:, :] jhlog,
double[:, :] reflog, double[:, :] warlog,
int width, int height):
I intend these to be numpy arrays in the pure python code and pass it to on to this function. At some point in the code, I access these arrays as:
for y in range(height):
for x in range(width):
jl = jhlog[x, y]
rl = reflog[x, 0]
wl = warlog[0, y]
When I cythonise the code, I get the following warning: Index should be typed for more efficient access.
I am not sure what I am supposed to do with this? I followed this guide here: http://docs.cython.org/en/latest/src/userguide/numpy_tutorial.html
but not sure what I should be doing to solve this warning.

A: that is a json data, if you save it in a file, it can be loaded with json module and simply iterate then add your condition
import json
import os
import sys
directory = os.listdir('/Users/Unicorn/Desktop/for all/change')
os.chdir('/Users/Unicorn/Desktop/for all/change')
for file in directory:
open_file = open(file,'r', encoding='utf-8')
read_file = open_file.read()
open_file.close()
# loads json file so it can be treated just like dictionary/list object in python
data_json = json.loads(read_file)
# iterate sheet item in data
for sheet in data_json:
# this is where you put your condition for sheetname == "Main"
if sheet['sheetname'] == 'Main':
# iterate over emp_detail because it is a list
for emp_detail in sheet['emp_details']:
# this is my simple method to replace item on a list
if 'Gaurav' in emp_detail:
emp_detail[emp_detail.index('Gaurav')] = 'Singh'
data_final = json.dumps(data_json)
open_file = open(file,'w', encoding='utf-8')
open_file.write(data_final)
open_file.close()

Thanx, regards.
A: You could take a look at docmosis which has a cloud-based document generator. It can generate PDFs and stream them back to the iPad or send as email. You upload a template to the cloud using the Docmosis web site, then you can generate documents from your iPad by sending a request (with data, images etc) to the Docmosis cloud.

df['sum'] = df.sum(axis=1)
when excuting that line I get the warning:
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead
See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
checking that link the talk goes on about ways to use loc in multiindex dataframes.
My dataframe is not multinidex.
What is the correct way to assign a column named "sum" with the addition of all the int values of the df?
This would not help to avoid the warning
x = df.sum(axis=1).copy()

t="1234567890"
result = re.sub(r'(\d)(?=(\d{3})+$)',r'\1,',t)
print("insert commas every three digits",result)
this works fine:
insert commas every three digits: 1,234,567,890
while
t="1234567890"
result = re.sub(r'(\d)(?=(\d{3})+)$',r'\1,',t)
print("insert commas every three digits:",result)
doesn't.
insert commas every three digits: 1234567890
I truly do not understand why does $ doesnot work in the second code, some help is needed on this.
A: The $ anchor is part of the lookahead in the original regex: match a digit followed by groups of triple digits until end of line.
Your broken variant looks for a digit before end of line, with a lookahead requiring groups of triple digits after the matched digit but before end of line.

C# Code:
var itemLists = new List<GetFiftyItemsData>();
itemLists.Add(new GetFiftyItemsData
{
SellerId = sellerId,
}.ThirdPartyData.Add(new ThirdPartyData {
}));
Model class:
class GetFiftyItemsData
{
public long SellerId { get; set; }
public List<ThirdPartyData> ThirdPartyData { get; set; }
}
A: This should do it
itemLists.Add(new GetFiftyItemsData
{
SellerId = sellerId,
ThirdPartyData = new List<ThirdPartyData> {
// item,
// item
})
});
And it's better not to name your field/property and type the same (ThirdPartyData).
A: I suggest you could declare variable step by step, let it be more readable, new ThirdPartyData first, then assign to GetFiftyItemsData, and add to itemLists.
long sellerId = 1;
List<ThirdPartyData> ThirdPartyData = new List<ThirdPartyData>();
ThirdPartyData.Add(new ThirdPartyData() { });
itemLists.Add(new GetFiftyItemsData
{
SellerId = sellerId,

I already built some code that is plotting a few different metrics per class. Plot_metric() is a self defined function.
gs = gridspec.GridSpec(1, 5, width_ratios=[5, 1, 1, 1, 1])
ax1 = plt.subplot(gs[0])

plot_metric(precision_per_class_array, "Class precision", ax3, cmap=plt.cm.Blues)
plot_metric(recall_per_class_array, "Class recall", ax4, cmap=plt.cm.Blues)
plot_metric(f1_per_class_Array, "Class F1", ax5, cmap=plt.cm.Blues)
I use every axis to plot a different metric and the confusion matrix as you can see in the picture.
But why is the last column smaller than the others? I would like it to be the same height as the other plots.

How do I accomplish what I need to do?
Thanks
A: Use this regex to extract fixed part separately and all numbers separately:
(?mi)^foo\\s+(\\d+)\\s+bar((?:\\s+\\d+)*)$
Then on the group(2) just use:
String[] nums = matcher.group(2).split("\\s+");
to get all numbers after bar.

Everytime when I resume this fragment, the listview inside the child-fragmnet is not recreating. Rather than it appending the same elements below. I mean if there are 5 list-items in real, everytime after resuming there will be 5 more same items at the end.
I have notifyDataSetChanged() but it is not working. This is my child-fragment code:
public class ChaptersListFragment extends SherlockListFragment {
OnChapterSelectListener mCallback;
ArrayAdapter<String> mAdapter = null;
public interface OnChapterSelectListener {
public void onChapterSelected(int position);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (mAdapter != null)
mAdapter.clear(); // I try this but not working
List<String> items = new ArrayList<String>();
for (int i = 0; i < CompetitiveProgramming.chapterList.size(); i++) {
items.add(CompetitiveProgramming.chapterList.get(i).chapterTitle);
}
mAdapter = new ArrayAdapter<String>(getSherlockActivity(),
R.layout.list_layout, items);
mAdapter.notifyDataSetChanged(); // I try this but not working
setListAdapter(mAdapter);
}
@Override
public void onStart() {
super.onStart();
if (getFragmentManager().findFragmentById(R.id.sub_category_fragment) != null) {
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}
}
@Override
public void onResume() {
super.onResume();
mAdapter.notifyDataSetChanged();
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mCallback = (OnChapterSelectListener) getParentFragment();
} catch (ClassCastException e) {
throw new ClassCastException(getParentFragment().toString()
+ " must implement OnChapterSelectListener");
}
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
mCallback.onChapterSelected(position);
getListView().setItemChecked(position, true);
}
}
Moreover when I am changing the orientation, the listview is recreating and there is only 5 items then. However, after resuming several times. the application is crashed with the following logcat:

How can I solve it? If any more code snippet is required, let me know in comment :)
A: I am not answering on the listview appending/refreshing problem, but the app crashing is due to a bug in the ChildFragmentManager. Basically, the ChildFragmentManager ends up with a broken internal state when it is detached from the activity.
See the link below and add that snippet in your parentFragment class.

The error that I am getting is Unexpected Beginning of Statement (near 'brand')
Brand is on the second line of the SQL statement.
The data that I am trying to enter:
INSERT INTO 'vehicles'
('reg_no', 'category', 'brand', 'description', 'dailyrate') VALUES
('BA5923W', 'car', 'Toyota', 'black 4 door 2.6 engine ', '9.99'),
('BA6611A', 'car', 'NISSAN ', '4 Door Saloon, Automatic', '9.99'),
('BM1245a', 'car', 'Golf', NULL, '9.00'),
('GA5955E', 'truck', 'NISSAN CABSTAR 3.0', 'Lorry, Manual ', '18.99')
cheers
A: Fixed. I was not closing the block of SQL code that created the table, which comes before this.
A: You have an syntax error at you query.
For columns names you should use Grave Accent ` char like
(`reg_no`, `category`, `brand`, `description`, `dailyrate`)
and for data line Apostrophe ' char like
('BA5923W', 'car', 'Toyota', 'black 4 door 2.6 engine ', '9.99')

01 to 1
02 to 2
all the way to 9?
Thanks
A: I assume the input is a string?
$str = "01";
$anInt = intval($str);
You may think that the leading 0 would mean this is interpreted as octal, as in many other languages/APIs. However the second argument to intval is a base. The default value for this is 10. This means 09->9. See the first comment at the intval page, which states that the base deduction you might expect only happens if you pass 0 in as the base.
A: $x="01";
$x=+$x;
$x="02";
$x=+$x;
...
or
$x=+"01";
should work for both int, and string
A: Do (int)$str; instead. It's up to 4x faster than intval().
A: $str = "05";
$last = $str[1];
A: $i = substr($input, 1, 1);
A: If you want to use the generic regular expression solution: 's/[0]([0-9])/\1/' (add in anchors as appropriate)
A: $str='05';
if(strpos($str,'0')==0 && strpos($str,'0') != false ){
$new = intval(substr($str,1));
}
A: you can use the predefined php function .
intval()
For Ex:
$convert = intval(01);
echo $convert ;
It will print 1(one);

Referring to other solutions on stackOverFlow, i have used different import methods like
import stripe from './stripe';
import * as stripe from './stripe';
but none of them can solve my problem.
What's wrong with my code?
Here are the codes:
For Stripe file:
import React from 'react'
import { Element } from "@stripe/react-stripe-js"
import { loadStripe } from '@stripe/stripe-js'
import "./Stripe.css"
const PaymentForm = require ('./PaymentForm.js')
const PUBLIC_KEY = "pk_test_XXXXXXX"
const stripeTestPromise = loadStripe(PUBLIC_KEY)
export default function Stripe() {
return (
<Element stripe={stripeTestPromise}>
<PaymentForm />
</Element>
)
}
For paymentFrom file:
import React, { useState } from 'react'
import { CardElement, useElements, useStripe } from "@stripe/react-stripe-js"
import * as axios from 'axios'
import "./Stripe.css"
const CARD_OPTIONS = {
iconStyle: "solid",
style: {
base: {
iconColor: "#c4f0ff",
color:"fff",
fontWeight: 500,
fontSize: "16px",
fontSmoothing:"antialiased",
},
invaild: {
iconColor: "#ffc7ee",
color: "ffc7ee"
}
}
}
export default function PaymentForm() {
const [success, setSuccess] = useState(false)
const stripe = useStripe()
const elements = useElements()
const handleSubmit = async (e) => {
e.preventDefault()
const { error, paymentMethod } = await stripe.createPaymentMethod({
type: "card",
card: elements.getElement(CardElement)
})
if (!error) {
try {
const { id } = paymentMethod
const response = await axios.post('http://localhost:8080/checkout', {
amount: 500,
id
})
if (response.data.success) {
console.log('Successful payment')
setSuccess(true)
}
} catch (error) {
console.log('Error', error)
}
} else {
console.log(error.message)
}
}
return (
<div>
{!success ?
<form onSubmit={handleSubmit}>
<fieldset className="FormGroup">
<div className="FormRow">
<CardElement options={CARD_OPTIONS} />
</div>
</fieldset>
<button>Pay</button>
</form >
:
<div>
<h2>You just bought a sweet saptula</h2>
</div>
}
</div>
)
}
A: I'd like to put a comment but I don't have the reputation to do it, so I'll submit an answer:
If you're trying to insert the elements provider following the documentation
the provider needs to be inserted this way:
import {Elements} from '@stripe/react-stripe-js';
you are importing this like
import {Element} from '@stripe/react-stripe-js';
it's possible that the element you're importing it's an interface or another object and not the provider you want

When I compare language names with no accents it works and the compare is true.
When I compare languages with accents, it doesn't think they are equal.
In this case they are NOT equal (but should be).
Language = "Español";
MonoTouch.Foundation.NSString s = new MonoTouch.Foundation.NSString(Language);
MonoTouch.Foundation.NSString l = new MonoTouch.Foundation.NSString ("Español");
In this example they ARE equal (notice no accents).
Language = "Deutsch";
MonoTouch.Foundation.NSString s = new MonoTouch.Foundation.NSString(Language);
MonoTouch.Foundation.NSString l = new MonoTouch.Foundation.NSString ("Deutsch");
I have tried cultureinvariate compares to no avail.
Am I missing something fundamental here?
I am using MonoTouch 1.4.4
A: the following matches as you require ignoring accents:
var Language = "Español" ;
MonoTouch.Foundation.NSString s = new MonoTouch.Foundation.NSString(Language);
MonoTouch.Foundation.NSString l = new MonoTouch.Foundation.NSString ("Español");
int result = String.Compare(s,l, CultureInfo.CurrentCulture, CompareOptions.IgnoreNonSpace);

I am trying to understand how to use keras for supply chain forecasting and i keep getting errors that i can't find help for elsewhere. I've tried to do similar tutorials; sunspot forecasting tutorial, pollution multivariate tutorial etc but i'm still not understanding how the input_shape argument works or how to organize my data to get it to be accepted by keras.

A: I think that the problem goes around TF version. Version compatibility between Keras and TF is a problem that probably anyone has faced, as TF API changes a lot in a small period of time.
I think that for Keras 2.2.X you need a TF version > 1.10.X
Try updating it and see if the problem is fixed!

SharedPreferences.Editor prefEditor = sharedPreferences.edit();
int balance = sharedPreferences.getInt("balance", 0);
prefEditor.putInt(balance, balance1);
prefEditor.commit();
A: From the comments beneath your question, I understand that you simply wish to update a value within sharedpreferences. Your first line is fine:
SharedPreferences.Editor prefEditor = sharedPreferences.edit();
This next line is then optional. Use it if you want to get at the existing value held under the key "balance" before you replace it. Otherwise it is not required and has no bearing on the 3rd line of code which replaces "balance" with a new value.
int balance = sharedPreferences.getInt("balance", 0);
Then I think your 3rd line should become:
prefEditor.putInt("balance", balance1);
That will replace the value held under the key "balance" with whatever value is held in balance1. Notice the quotes around "balance" that you did not have in your original code.

I want to plot a stereographic projection with contoruf and want to color the higher parts in the Z direction in Matplotlib.
For that i have two questions.
*
*I’m plotting with contourf before im using meshgrid and griddata, the the other edges are not smooth how can i smooth them?
i
*I want to have a log scale in Z how can i do that, i tried to use ticker.LogLocator but then i got just some parts colored.
Here my code:
# craation of a 2D grid
xi = np.linspace(min(X), max(X))
yi = np.linspace(min(Y), max(Y))
X1, Y1 = np.meshgrid(xi, yi)
##### interpolation
Z1 = griddata(X, Y, Z,xi,yi)
plt.contourf(X1,Y1,Z1,50,cmap=plt.cm.rainbow,vmax=abs(Z1).max(),
locator=ticker.LogLocator)
plt.colorbar()
plt.xlim(-1,1)
plt.ylim(-1,1)
plt.show()
plt.set_zscale('log')
plt.set_xlabel('X')
plt.set_ylabel('Y')
plt.show()
A: Answering the first question:
You can smooth the contour values doing:
zmin = Z1.min()
zmax=Z1.max()
levels=linspace(zmin, zmax, 400)
and then pass levels as an argument to plt.contourf().
To smooth the outer edges you have to use more values in your 2-D grid, which can be achieved passing the number of values you want when using linspace():
nx = 1000
ny = 1000
xi = np.linspace(min(X), max(X), nx)
yi = np.linspace(min(Y), max(Y), ny)

How can i open the new popup , when trying to open the same web page in default web browser like chrome , IE they are opening the pop up.
For creating the pop up i am using the following code.
Group group= new Group();
Scene scene= new Scene(group);
fxpanel.setScene(scene);
WebView webview = new WebView ();
group.getChildren().add(webview);
it().getScreenSize().height);
webview.setVisible(true);
webview.getEngine().setOnAlert(null);
eng= webview.getEngine();
eng.setJavaScriptEnabled(true);
try{
String url ="http://www.lawcrux.com/mkwebchatblog/loginp.aspx";
eng.load(url);
eng.setCreatePopupHandler(
new Callback<PopupFeatures, WebEngine>() {
@Override
public WebEngine call(PopupFeatures config) {
JOptionPane.showMessageDialog(null,"clicked");
return eng;
}
});
A: You need to create WebView popup window yourself and provide WebEngine from callback. If you need new window, create new Stage with that WebView (not Swing one, JOptionPane can't store JavaFX WebView).
See next example:
WebView wv = new WebView();
wv.getEngine().setCreatePopupHandler(new Callback<PopupFeatures, WebEngine>() {
@Override
public WebEngine call(PopupFeatures p) {
Stage stage = new Stage(StageStyle.UTILITY);
WebView wv2 = new WebView();
stage.setScene(new Scene(wv2));
stage.show();
return wv2.getEngine();
}
});
StackPane root = new StackPane();
root.getChildren().add(wv);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
wv.getEngine().load("http://www.i-am-bored.com/pop_up_blocker_test.html");

I wrote the below code
String s = new String("Tushar");
String s1 = new String("Tushar");
System.out.println("String HashCode");
System.out.println(s.hashCode());
System.out.println(s1.hashCode());
StringBuffer stringBuffer = new StringBuffer("Tushar");
StringBuffer stringBuffer1 = new StringBuffer("Tushar");
System.out.println("StringBuffer HashCode");
System.out.println(stringBuffer.hashCode());
System.out.println(stringBuffer1.hashCode());
StringBuilder stringBuilder = new StringBuilder("Tushar");
StringBuilder stringBuilder1 = new StringBuilder("Tushar");
System.out.println("StringBuilder HashCode");
System.out.println(stringBuilder.hashCode());
System.out.println(stringBuilder1.hashCode());
The output was as follows
String HashCode
-1778537625
-1778537625
StringBuffer HashCode
715152323
99120402
StringBuilder HashCode
1616769989
942619632
Why the hashcodes of StringBuilders and StringBuffers don't match.
Are these just memory locations to which they are allocated or the hash code is created based upon the string passed?
EDIT:
Understanding : The hashcode of the value remains same irrespective of the way it is created.
Confusion : What are the values printed (hash of instance variable, what does is mean?).
A: Every class can choose to calculate the hash code in it's own way. Hash codes don't have meaning, and very simple rules (abbreviated):
*
*Objects where equals() return true must return same hash code.
*Objects where equals() return false should return different hash code, to the best ability of the class, to ensure better performance of hash tables such as HashMap and HashSet.
Since a String with value "ABC" and a StringBuilder with value "ABC" are not equal, there is no requirement that they return the same hash code.
If you extract a String value from the StringBuilder, then that string value must have same hash code as another string of the same value, and it will, so the following two expression will return the same value:
new String("ABC").hashCode()
new StringBuilder("AB").append("C").toString().hashCode()
As a side note: Neither StringBuilder nor StringBuffer implements equals() and hashCode(), so their equality is based on identity, not value. Two StringBuilder objects with same value will still not be "equal", and will therefore (most likely) not have same hash code.
A: The lines stringBuilder.hashCode() and stringBuffer.hashCode() gets you the hash of the instances of the stringBuilder and stringBuffer hence the difference.
Since the String are immutable (see my edit), getting the hash of the string of the stringBuilder and stringBuffer will be the same.
So:
System.out.println(stringBuffer.toString().hashCode());
System.out.println(stringBuffer1.toString().hashCode());
System.out.println(stringBuilder.toString().hashCode());
System.out.println(stringBuilder1.toString().hashCode());
all will return the same hash
edit:
Note also, that the computing of the hash of the string is:
s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]
So, even that there is only one copy of the string "abc" in memory, the hash of the same string return the same value at each run.

my code:
<?php
$target_dir = "uploads/";
$target_file = $target_dir . date('d_m_Y_H_i_s') . '_'. $_FILES["fileToUpload"]["name"];
if($target_file = null) {
echo"nada";
}
$uploadOk = 1;
$imageFileType = pathinfo($target_file, PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( date('d_m_Y_H_i_s') . '_'. $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
A: Using str_replace would be the easiest way in my opinion.
$target_file = $target_dir . date('d_m_Y_H_i_s') . '_'. str_replace(' ','-',$_FILES["fileToUpload"]["name"]);

From this html i need to extract the lines beforeth of < br > tag
line1 : Get the IndianOil Citibank Card. Apply Now!
line2 : Get 10X Rewards On Shopping - Save Over 5% On Fuel
how it would supposed to do in python?
A: I think you just asked for the line before each <br/>.
This following code will do it for the sample you've provided, by striping out the <b> and <a> tags and printing the .tail of each element whose following-sibling is a <br/>.
from lxml import etree
doc = etree.HTML("""
<li class="taf"><h3><a href="26eOfferCode%3DGSONESTP-----------" id="pa1">
Citibank <b>Credit Card</b> - Save over 5% on fuel | Citibank.co.in</a>
</h3>Get the IndianOil Citibank <b>Card</b>. Apply Now!
<br />
<a href="e%253DGOOGLE ------">Get 10X Rewards On Shopping</a> -
<a href="S%2526eOfferCode%253DGSCCSLEX ------">Save Over 5% On Fuel</a>
<br />
<cite>www.citibank.co.in/<b>CreditCards</b></cite>
</li>""")
etree.strip_tags(doc,'a','b')
for element in doc.xpath('//*[following-sibling::*[name()="br"]]'):
print repr(element.tail.strip())
Yields:
'Get the IndianOil Citibank Card. Apply Now!'
'Get 10X Rewards On Shopping -\n Save Over 5% On Fuel'
A: Solution without relaying on <br> tags:
import lxml.html
html = "..."
tree = lxml.html.fromstring(html)
line1 = ''.join(tree.xpath('//li[@class="taf"]/text() | b/text()')[:3]).strip()
line2 = ' - '.join(tree.xpath('//li[@class="taf"]//a[not(@id)]/text()'))
A: As with all parsing of HTML you need to make some assumptions about the format of the HTML. If we can assume that the previous line is everything before the <br> tag up to a block level tag, or another <br> then we can do the following...
from BeautifulSoup import BeautifulSoup
doc = """
<li class="taf"><h3><a href="26eOfferCode%3DGSONESTP-----------" id="pa1">
Citibank <b>Credit Card</b> - Save over 5% on fuel | Citibank.co.in</a>
</h3>Get the IndianOil Citibank <b>Card</b>. Apply Now!
<br />
<a href="e%253DGOOGLE ------">Get 10X Rewards On Shopping</a> -
<a href="S%2526eOfferCode%253DGSCCSLEX ------">Save Over 5% On Fuel</a>
<br />
<cite>www.citibank.co.in/<b>CreditCards</b></cite>
</li>
"""
soup = BeautifulSoup(doc)
Now we have parsed the HTML, next we define the list of tags we don't want to treat as part of the line. There are other block tags really, but this does for this HTML.
block_tags = ["div", "p", "h1", "h2", "h3", "h4", "h5", "h6", "br"]
We cycle through each <br> tag stepping back through its siblings until we either have no more, or we hit a block level tag. Each time we loop we get add the node to the front of our line. NavigableStrings don't have name attributes, but we want to include them hence the two part test in the while loop.
for node in soup.findAll("br"):
line = ""
sibling = node.previousSibling
while sibling is not None and (not hasattr(sibling, "name") or sibling.name not in block_tags):
line = unicode(sibling) + line
sibling = sibling.previousSibling
print line
A: I dont know whether you want to use lxml or beautiful soup. But for lxml using xpath here is an example
import lxml
from lxml import etree
import urllib2
response = urllib2.urlopen('your url here')
html = response.read()
imdb = etree.HTML(html)
titles = imdb.xpath('/html/body/li/a/text()')//xpath for "line 2" data.[use firebug]
The xpath I used is for your given html snippet. It may change in the original context.
You can also give cssselect in lxml a try.
import lxml.html
import urllib
data = urllib.urlopen('your url').read()
doc = lxml.html.fromstring(data)
elements = doc.cssselect('your csspath here') // CSSpath[using firebug extension]
for element in elements:
print element.text_content()

int fd=socket(AF_INET, SOCK_RAW, IPPROTO_RAW);
struct sockaddr_ll sa;
memset(sa, 0, sizeof(sa));
// ip4h is the IPv4 datagram unwrapped in the user space and ready to be
// sent to the kernel
if (sendto(fd, iph, iplen, 0, (struct sockaddr *)&sa, sizeof(sa)) != iplen) {
// Error processing.
}
The above injects full IPv4 packets (including the IPv4 headers), and the IPv4 payload gets processed appropriately by the Linux stack. How should the above be modified for use with IPv6 packets? The following adjustments I tried did not work:
int fd=socket(AF_PACKET, SOCK_DGRAM, htons(ETH_P_ALL));
sa.sll_family=AF_PACKET;
sa.sll_protocol=htons(ETH_P_IPV6);
sa.sll_halen=ETH_ALEN;
sa.sll_ifindex=2; // <index of eth0>
if (sendto(fd, iph, iplen, 0, (struct sockaddr *)&sa, sizeof(sa)) != iplen) {
// Error processing.
}
Any thoughts on why the above doesn't work with raw IPv6 datagrams? 'tcpdump ip6' does show the IPv6 packets I'm inserting, which suggests the kernel sees them! It just happens to be ignoring them as well.

But now, the application that I'm coding has 3 different methods for Log in/sign up:
*
*Normal login (username/password)
*Connect with Facebook
*Connect with RunKeeper
Each one of those methods works nice if you use them separately. For example I can do a normal login with username and password, I get this information from the user and I send It to the server using HTTPRequest library and the server gives me a valid access_token to log in with no problem. Same with Facebook or runKeeper.
But if I do the following steps anything works:
*
*I log in with Facebok or RunKeeper (doesn't matter which one) using an account that it's already linked to a certain user (we can call him X).
*I request to Facebook/RunKeeper the access_token and the userID of the user and I send this information to my server.
*My server gives me a valid access_token for the user X and I load the dashboard with his information.
*The user X Logs out and I clear all the information in NSUserDefaults and synchronize it.
*The user Y logs in using using his username and password (log in method number 1).
*My server gives me a valid access_token for the user Y and I load the dashboard with his information.
*The user Y logs out and I clear all the stored data in NSUserDefaults and synchronize it.
*Finally any other user (Z for example) logs in again using Facebook/runKeeper.
*I get all the information required from the social network and I send it to my server.
*My server gives me a valid access_token and I load the dashboard, but it's not the dashboard of the user Z, It's the dashboard from the last user that has logged in using username/password.
I know that reading those steps you can think that It's a problem with the server, but i did some tests using cURL and the response for the tokens are always correct. Then I thought that it could be some problem in the iOS App but I couldn't see anything with the breakpoints and the NSLogs i did.
The i read about the cache in the ASIHttpRequest library and I added thos two lines of code in all my requests to the server for disabling all the cache system but it didn't work:
[request setCachePolicy: ASIDoNotWriteToCacheCachePolicy | ASIDoNotReadFromCacheCachePolicy];
[request addRequestHeader:@"Cache-Control" value:@"no-cache"];
I don't know if anyone of you had the same problem or If you've got any idea of what can I try, but It will be very appreciated.
If you need more information just tell me an i'll see what can i do
Thanks!
A: the important advice to stop use ASIHTTPRequest because it's not working well with ios 7
i'm facing many issues with ios 7 after release it to production
you can use this instead
