But it seems that unlike the ykeys attribute there is no way to pass a list of values to xkey (both month and year).
So if I just use the month, there's no way to identify the year:
xkey: ['month']
and if I use the year, no way to identify the month:
xkey: ['year']
Has anyone found a way around this so I can use both without having to concatenate the values outside the chart ?

But as far as it is described you want to change only the spriteTexture of your hero ( to give a change skin effect). On the hero sprite node ( and any other SKSpriteNode is possible to change only the TEXTURE, to do so you must do something like:
[self setTexture:[SKTexture textureWithImageNamed:@"heroNewSkin.png"]];
This should change the texture ( appearance) of your hero on the fly. Remember that the image should be imported into your Xcode project. And the image should be the same size as the previous one, if not you should change the size property of you hero SKSpriteNode.

Music is useless! Right?
As has been pointed out in several other comments, music is math so as a unified 'this music means that maneuver' it's easily cracked. That doesn't mean it can't be used. With where we are at in todays world with AI, and from the sounds of your more advanced AI, I don't see why your series of battle conductor computers wouldn't be able to work with soldiers directly.
Your enemy AI doesn't understand emotion
Instead of a single battle hymn playing, each soldier could have their own musical feed. Just like in real world military training where reactions to events are ground into you to the point they become natural, do the same thing but teach each soldier to react to their emotion directly. Teach combat maneuvers, but tie them to emotions. Since each person responds to music differently, this would essentially create a custom encryption for each solder's direction.
As an example, some people jump at loud noises while others freeze or maybe even take a step back. In training find out each soldiers reaction, and use that gut instinct in battle. One person hears a random cannon go off, and they drop to the ground taking cover just when they were fired on. Another stops moving so they stop making noise for half a second just as they could have been detected by sound nearby.
This can be applied to noise levels as well as types of music for each individual. Metal tends to be background noise to me and makes me tired if its too loud too long. String based classical gets my heart pumping while symphonic metal draws my attention. I get irritable at rap.
TL;DR
Soldiers trained to respond to emotion, and trained to focus on their emotions in battle could be individually directed, giving the idea of music for tactics a path to success.

It is possible to be well diversified with individual stocks--through careful selection or index skimming for example--and some brokers have tools to analyze your portfolio. Know your limits @Pac2015 and know that aggressive investing can result in aggressive losses as well as gains. Those analysis you quote are often wrong.

I'm not sure at all how this works, but it works when I simply visit site1 first, then visit site2 in a browser.

I included some commented out lines because those are things i've tried, but ended up in nothing being printed to the screen. As is, I pull the very little data I can access without first visiting site1.

So is it true, that I cannot create real time shadow shaders as a workaround to the limitations of the free version?

Override getCount() method and return here the total amount of images you need to show.
In the getView load with Glide only ONE url (remove the for loop), the getView method will be called N times to show in the list the "total" amount of images you returned in the getCount method, the position parameter in the getView method will run from 0 to (total - 1).
You should map 1 position to 1 url, maybe you will need to change the way you access the objects that contain the urls.

can you elaborate more on "Why I can print foo: 1 in JavaScript"?
If I run this code
var t = {foo: 1};
It will become the property for object "t". The same behaviour will be implement if you use this code
var t = {foo: 1, bar: 2};
You can access it by "t.foo" and "t.bar" and it will return the value either "1" or "2".

It is a different exercise, it is a different skill that you are learning. (The non-linear nature of the band helping you out most at the bottom, where the shoulder mobility that most people lack is most important, making it easier to start with bad shoulder position!)
That trainer believes the pull-down is a more appropriate accessory exercise than the band-assisted chin to develop the strength needed to proceed to learning the chin-up skill. One can agree with him somewhat on the basis that bad-form is likely more obvious on the pull down. One can certainly do "too-much-too-soon" on the assisted pull-up machine and learn the skill incorrectly with poor shoulder mechanics hiding missing strength.
To someone who is is not a baseball enthusiast, what is the difference between the throw a second baseman uses to home plate and a pitch? Is it not just a harder version of the pitch with less accuracy? Of course if you've played baseball you know it's a totally different skill and you don't use one to improve the other. You use accessory exercises appropriate to that skill.
(I am not saying I 100% agree with him, just trying to restate his point as I understand it!)

NSArray *trackIDs = blah; // the ids you're searching for
NSString *searchFilter = @"databaseID == %@";
NSMutableArray *filters = [NSMutableArray arrayWithCapacity:[trackIDs count]];

[filters addObject:searchFilter];
}
searchFilter = [filters componentsJoinedByString:@" OR "];
NSArray *trackResult = [[libraryPlaylist tracks] filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:searchFilter argumentArray:trackIDs]];
And that works just fine if the trackIDs array only contains a single item, so there's no need to write special code for that case.

You can see that the salt matches, and the key matches the first half of what OpenSSL shows, so I seem to be on the right track, but there are two main questions:
Why are the values for key and iv from OpenSSL twice as long as PyCrypto (and presumably AES256) allows?
How do I generate the correct values? The technique I'm using was taken from a blog, but if the IV is always supposed to match the block size (16 bytes), MD5 will never work. And even if I could figure out where the other half of the key comes from, PyCrypto would refuse it for being too long.
I realize I'll need to remove the padding as well, but I left that out for brevity.

qDebug() << "UserRole is " << ui->comboBox->itemData(index);
}
The second time add the items calls the current index changed event every time, the first time just on the first addItem.
In the second run, after sort, all user data is 0.
Any ideas?

If i remove the last block writing to Matrix2, the code runs in a few milliseconds. If the code is executed completely it seems to fill matrix1 as soon as i acces matrix2 which takes 16 seconds to execute. Is there a way to get reasonable performance here?
My usecase is the following: I retrieve data vector-vise and have to add it as a column to Matrix1 and as a row to Matrix2. There is no way to write Matrix1 first and then write Matrix2, i have to write them at the same time.

Here's an example from my app.js:
/**
* "Register for a class" page
*/
if (document.body.classList.contains("page-id-4136")) {
import(/* webpackChunkName: "register-for-a-class" */ './pages/register-for-a-class/main')
}
In this case, the 'pages/register-for-a-class/main.js' file page uses Vue as a dependency, but is the only page on the site so far to require it. I'd rather not bundle Vue into vendor.js when it's only being used on this page. I've tried to include Vue itself as a dynamic import by trying the following:
// pages/register-for-a-class/main.js
import(/* webpackChunkName: "vue" */ 'vue').then(({ default: Vue }) => {
new Vue({
...
})
})
But that gives me an error in webpack bundling that says Module parse failed: 'import' and 'export' may only appear at the top level. So I also tried this:
// app.js
/**
* "Register for a class" page
*/
if (document.body.classList.contains("page-id-4136")) {
import(/* webpackChunkName: "vue" */ 'vue').then(({ default: Vue }) => {
import(/* webpackChunkName: "register-for-a-class" */ './pages/register-for-a-class/main')
})
}
That just flat out doesn't change anything. No "vue.bundle.js" file is created, and, naturally, loading the page creates a Vue is not defined error.
So here's what I'm really asking. What would be absolutely fantastic is if I could automatically have the pages/register-for-a-class/main.js just call a normal static import (e.g. import Vue from 'vue') and have webpack generate both the register-for-a-class.bundle.js file and a corresponding register-for-a-class-vendor.bundle.js and dynamically import that vendor bundle automatically. It that possible?
Here is my current webpack.common.js file (I'm using webpack-merge):
const path = require('path')
const webpack = require('webpack')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')
const VueLoaderPlugin = require('vue-loader/lib/plugin')

I thought I have not set up properly the constraint on the GoalsVC, but after multiple verifications I noticed I am using the same constraints as the second picture (assistVC) scene.
I even deleted the goalsVC scene and copied the assistVC scene in order to make sure I have the same constraints and just hooked up the Goal swift file and each outlets again. Thought it maybe an issue with the View content Mode, but nope.
However the result is still different between them. Any ideas or suggestions.

The errors are showing when there's no input on the input field when i hit on the submit button, no problem with that, but even there's an input the errors are still being shown. So catch is always being called. When i remove try and catch I can easily save data to the database but there's no validation.
Thank you and more power.

Duplicate paths can be found in both tables (the unique constraint is on another column).
I try to find if there are paths in table1.paths1 that don't exist in table2.paths2.
My problem is the '/' that is sometimes exists before the path (like in the case /dir/file).
To do it I use:
SELECT count(*) FROM (

How can I make the '/' optional?

A crucial part of it will be the GUI with a lot of 2D drawing going on. In the past, I've always used Swing for my projects. <PERSON>, I can't use Swing on Android (and I guess it wouldn't be smart performance-wise anyways).
So is there any GUI API I can use which won't involve too much effort when porting my program to android?
Any advice is appreciated!

In bash you can use I/O redirection and Process Substitution to pipe stdout, stderr through another process.
#!/usr/bin/env bash
# setup fd-3 to point to the original stdout
exec 3>&1
# setup fd-4 to point to the original stderr
exec 4>&2
# get the prefix from SUPERVISOR_PROCESS_NAME environement variable
printf -v PREFIX "%-10.10s" ${SUPERVISOR_PROCESS_NAME}
# reassign stdout and stderr to a preprocessed and redirected to the original stdout/stderr (3 and 4) we have create eralier
exec 1> >( perl -ne '$| = 1; print "'"${PREFIX}"' | $_"' >&3)
exec 2> >( perl -ne '$| = 1; print "'"${PREFIX}"' | $_"' >&4)
# from here on everthing that outputs to stdout/stderr will be go through the perl script
echo "I will be prefixed"
# don't forget to use exec
Now you can setup supervisor to use stdout and stderr for logging:
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
and as command use a bash script that setups the I/O redirection.

I have two instances of IntegrationFlow linked to two different source types. One is linked to a SFTP source an the other one is linked to a Datasource.
When a SFTP message is consumed after several steps (unzip files containing XML files, check XML files validity against XSD schema, split XML files and persist data corresponding to a part of XML file), a second Workflow, running in parralel, consumes every persisted data from a datasource in order to push them into a Kafka topic. So I want to attribute more resources on the first IntegrationFlow. For every InegrationFlow the max fetch size is setted to one.

Problem is, the method that will resign the responder on the text field is not being called. I have put in NSLogs to see what is being called and what isn't, and the setup is called (i.e. UIToolbar initialization, button adding, adding the toolbar to the text field, etc.), but the method isn't ever called when the "Done" button is pressed. In fact, the button doesn't even look "clickable".
- (void) viewDidLoad
{
UIToolbar *toolbar = [[UIToolbar alloc] init];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(donePicker:)];
UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[toolbar setItems:@[doneButton, spaceItem]];
self.textField.inputAccessoryView = toolbar;
}
-(void)donePicker:(id)sender
{
[self.textField resignFirstResponder];
}
I've attempted to use both [self.textField resignFirstResponder] as well as [self.view endEditing:YES], both bearing no fruit here. Any ideas, folks?

testEnv\_db.001: No such file or directory
Error opening database environment
DbEnv<IP_ADDRESS>open: No such file or directory
The code of the console program is based strongly off the examples in the Berkeley DB Transactions guide, and here's the text of the program up to the error, under int main().
String^ key_allkeys = "_ALLKEYS";
String^ key_valcount = "_COUNT";
// 1. Print some information to the screen, prompt user to enter path for key-value pair location:
Console<IP_ADDRESS>WriteLine("Oracle Berkeley DB Example Database Creator");
Console<IP_ADDRESS>WriteLine();
Console<IP_ADDRESS>WriteLine("Enter the path to the text file of key-value pairs:");
String^ kv_path = Console<IP_ADDRESS>ReadLine();
// 2. Declare initial variables:
String^ totalkeys;
int totalval;
// 3. Open the database:
u_int32_t env_flags = DB_CREATE | DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_MPOOL | DB_INIT_TXN;
std<IP_ADDRESS>string envHome("testEnv");
u_int32_t db_flags = DB_CREATE | DB_AUTO_COMMIT;
Db *dbp = NULL;
const char *file_name = "mydb.db";
DbEnv myEnv(0);
try
{
myEnv.open(envHome.c_str(), env_flags, 0);
dbp = new Db(&myEnv, 0);
dbp->open(NULL, file_name, NULL, DB_BTREE, db_flags, 0);
}
catch(DbException &e)
{
std<IP_ADDRESS>cerr << "Error opening database environment: " << std<IP_ADDRESS>endl;
std<IP_ADDRESS>cerr << e.what() << std<IP_ADDRESS>endl;
exc_block(); // Block
return (EXIT_FAILURE);
}
It should be fairly obvious that the program is failing right around the try/catch blocks. I've read the manual (literally RTFM) and I couldn't figure it out - the DB_CREATE flag is specified for both the environment and database, so there shouldn't be an issue here.
Any ideas?

Following what you described as a sequence of execution, here is a simplified example of how I would implement the chain:
Transformer.java
public interface Transformer<IN, OUT> {
OUT transformToDomain(IN dto);
IN transformToDTO(OUT domainObject);
}
Validator.java
public interface Validator<T> {
boolean isValid(T object);
}
Service.java
public interface Service {
void save(Object object);

And the implementation that binds everything:
ProcessChain.java
public class ProcessChain {
private Transformer transformer;
private Service service;
private Validator validator;
Object process(Object dto) throws MyValidationException {
Object domainObject = transformer.transformToDomain(dto);
boolean isValid = validator.isValid(domainObject);
if(!isValid){
throw new MyValidationException("Validation message here");
}
service.save(domainObject);
return transformer.transformToDTO(domainObject);
}
}
I haven't specified any Spring related things here because your question seems to be a design question rather than a technology questions.
Hope this helps

If you are using Maven as your build tool, try and do a build from the terminal (outside Eclipse). If that builds well, then maybe Eclipse has not refreshed your Maven dependencies. You would have to verify that by looking into the Maven Dependecies library (Eclipse library that is) to see if your Lombok dependency is showing there.
Also check if Eclipse has Annotation Processing is enabled, go to Properties -> Java Compiler -> Annotation Processing
It's a shot in the dark so I hope it helps

To sum up, what I'd like to do is what in Apama you do by typing

In javascript, scope will be defined at lexical time, so the variables in callback function will be assigned to scope before the ajax query is completed.Values to the variables will only be assigned during execution after the ajax query is completed.
When a function is called multiple times same memory location of variables is used each time in javascript, same applies here too.But the execution of the callback function will be synchronous and not parallel.And the order of callback function execution will be the order in which jquery returns.So no collision will occurs.

Here what is happening is that, you are trying to push 'numbers' array to 'sn' array.
Statement is "sn.push(numbers);"
So here we are pushing the Object reference of numbers array to 'sn', means you are not making a copy of numbers array and pushing to 'sn'.
You are just pushing the Memory reference of 'numbers' array.
So during first iteration, 'sn' will have exact value as you calculates.
But during the second iteration 'sn' will have two arrays. But those two values are same and points to the same memory location of 'number'.
So here what you should do is create a clone of 'numbers' array during each iteration.
if (sn.includes(numbers)) { check = false };
var cloneArray = numbers.slice(0);
sn.push(cloneArray);

That number you are passing in is called minSplits. It has an effect on the minimum number of partitions, that is all.
def textFile(path: String, minSplits: Int = defaultMinSplits): RDD[String]
Number of splits should be governed by getSplits method (docs)

I believe your specific problem is with "$A2". This should be dynamic. The next row should be $A3, then $A4, and so on.
You can achieve this by treating your vlookup as a string. Break it after the $A to use your variable then rejoin the string.
For example: "...RROR(VLookup($A" & j & ", Tabl...."

to easily and quickly find and retrieve matches, i load arrays with criteria and set filters. copy special visible to grab the filtered results then split with getfromclipboard to load an array.
combobox's are great when i need a different level of matching, specifically, when i need to match a users request from a pool of possibilities. frequently the results i pulled from the the clipboard will populate a combo list
or
i may send it to a dictionary as an item or populate keys. dictionaries are a deceptively simple way to find unique values or create arrays with relationships to other data. added benefit, they can hold just about anything as an item and the key is similar except it cannot be an array and it must be unique from the other keys.
hope you find something helpful, best of luck!

Version one has just been released and is working great. For version two however, I want to completely redesign the UI and use a front-end framework such as AngularJS. I've been looking at the (MEAN stack) and it looks really promising. Before goin into too much details, I will try to explain the purpose and working of the app so hopefully you will understand my question later on.
My app is a streaming service and has 4 simple models: user, room, song, playlist. These are modeled through Schema's in Mongoose and are stored in the MongoDB database. When a user visits the app, it serves all the HTML through Node.js and Express (and Jade as templating engine). If the user then registers, Socket.io lets the server know a user register, that is then saved to the database and the user is joined in the lobby room. In this room, users can chat, listen to music, etc. This is what I've been using Socket.io for, the communication between users themselves and my server (the server sometimes serves html too through Socket.io). Basically all the messages between Socket.io and the server are really small (chat messages, room objects, song objects, etc).
I'm quite happy with this approach, however, on the client side, the code is not really separated. There are currently two JS files serving the logic. One handles the Socket.io events and manipulates the dom. The other one is a common JS file that does a bit of everything. These two files are now about 5000 lines each. This worries me and I want to find a solution for this in v2.
So I've been looking at AngularJS in the MEAN stack and how to incorporate it in my app. My question is, will this solve my client side problems and can would you recommend taking the effort to do so. Also, how well will Socket.io work with AngularJS? Having both of them might be an overkill for what I'm doing. Do you know of any possible other framework that might be easier to integrate with my current environment? I know it's a bit of a subjective question but if you have any tips or do or don'ts, thanks for sharing! I really appreciate your feedback and if you need more information, I'd be happy to share it with you!

I have search every file in the core folder of codeIgniter and I have made a new constant that's APPPATH_OWN and by every function of view, controller models and so on I have made a function to first check OWN pathfile than the normal one.
In the folder core I have finally edited the following files.
Router.php
Common.php
Config.php
CodeIgniter.php

In the folder databases I have changed the DB.php folder.
I had hoped that there was an easier solution.

Your code does have more error.
But if you want to get all information in page 3 you must do in page 3
$value = mysql_real_escape_string($_GET['valuep1']);
$countryu = mysql_real_escape_string($_GET['country']);
A name in a form is the name how you can get the value. On page one your value to get it is value. That is confusing you better can call it search. And if you then do $_GET['search'] then you will get the value.
First thing to do is to better understand how a form works and use better names so that you can't confusing yourself. More info here http://www.w3schools.com/php/php_forms.asp

For example Oracle first limits results and applies ordering on said results. It makes sense when you think about it from a performance point of view. In MySQL you are actually ordering the entire DB(> 1000 records) to get 2

The most common of them is (point 4 from the link) :
max_allowed_packet = 1M
Try to increase to 4M, 8M or 16M (to do that you need access to mysql config file)
One advice don't show mysql server settings (host, login and so on)

On each of these, you can perform rotation and translation transformations. So I created a parent class called GeometricObject, objects which can be transformed in geometric space.
Now, I am able to created pure virtual class functions with different implementations for each child class. Now, I want a general function which can take GeometricObject, but "smartly" return what type I actually put in. For example, I have the following function which rotates a Geometric object to a different coordinate system:
GeometricObject rotate_object_to_global_coordinate_system(GeometricObject object) {
object.rotateX(90); // Pure virtual functions
object.rotateY(90);
object.rotateZ(90);
return object;
}
If I input a MathLine into it, I expect the function to "cast" into a MathLine, perform MathLine's implementation of my virtual functions, and return a MathLine.
I've searched everywhere for this and it seems like this can be done by using either pointers (auto_ptr) or casting (dynamic_cast). This doesn't seem good because I've read that it's a bad way to do it because it sacrifices a noticeable amount of performance. It also seems like a simple feature that a high-level programming language should have. Can this be done?
I think it's really important for me to do this because otherwise, I would have to write separate functions which basically perform the same virtual functions for different child classes. I would have to write:
MathLine rotate_line_to_global_coordinate_system(MathLine object);
MathPoint rotate_point_to_global_coordinate_system(MathPoint object);
MathPlane rotate_plane_to_global_coordinate_system(MathPlane object);
// etc.

[nextKit searchForPOIsOnDataPoint:2];

//The Y is also the same as nextKit's Y
//What happened?
//Before, kit.visiblePoints[0] was different from nextKit.visiblePoints
//After calculating nextKit's visiblePoints through searchForPOIsOnDataPoint, it changes
This happens whenever I do searchForPOIsOnDataPoint: on another instance of a class. It overrides the values for the instance previously declared & assigned. Does anyone have an idea of what could happen inside of the class implementation that will cause this? I have these values in the class which are determined by the DataPoint:
@interface CalculationKit : NSObject
//Data From XML File
@property NSMutableArray * latitudeValues;
@property NSMutableArray * longitudeValues;
@property NSMutableArray * visiblePoints; //Array of coordinate values
//..//
@end
In the implementation I have variables to store the latitude and longitude values to calculate a single point:
@interface CalculationKit () {
//The values used in calculation of a single point
double workingLatitude;
double workingLongitude;
//...//
}
And I get individual data to calculate each point by using this code inside searchForPOIsOnDataPoint:
- (void) searchForPOIsOnDataPoint: (int) _DataPoint {
//Gets XML Values for current data point
workingLatitude = [[self.latitudeValues objectAtIndex: _DataPoint] doubleValue];
workingLongitude = [[self.longitudeValues objectAtIndex: _DataPoint] doubleValue];
//..//
}
I'm really confused because searchForPOIsOnDataPoint does not depend on another CalculationKit class.

Sounds easy, right?
I've decided to make simple console prototype and code look something like this:

{
StreamReader reader = new StreamReader( response.GetResponseStream());
while (!reader.EndOfStream)

Console.WriteLine(reader.ReadLine());
}
reader.Close();
response.Close();
}
This code works on most other sites, but here I get errors 404 (most of the time), 502 or timeout.
I've consulted with Firebug (I've took Accept and compression info from there) but to no avail.

I have 2 functions that try to parse out the same data from the same csv file. I've put thisdata_out.seek(0)
reader = csv.reader(data_out)
next(reader,None)
which worked for each function to parse it but then it won't work if the variables are outside of the function. I am trying to use the return value from each function outside such as:
counter_p = participated()
counter_g = generalNumber()
success_percentage = [counter_p.get(primary)/counter_g.get(primary, 1) for primary in counter_p]
What I have is that is that if both functions are active: counter_p = {A01:5, A02:1, A03:2} and counter_g ={} but if I make participated() inactive then counter_g = {A01: 6, A02: 3, A03: 5}

You could use the xp_cmdshell or powershell to change or start some options. For example if you want to start your SQL agent do this:
xp_cmdshell 'net start sql server agent (instancename)'
If you want to change server protocols with powershell, check out - http://msdn.microsoft.com/en-us/library/dd206997.aspx
Powershell is like it says, powerful.

I develop Xpages applications locally using Lotus Domino Designer as a web server, but for browser, not for Notes client.
Problem
I have not found a solution for search in another database using @DbLookup/@DbColumn, because I do not know how to define the server part:
"" does not seems working in case of browser
database.getServer() returns my Lotus Notes username, which also does not seems to work
Question
What formula/SSJS code can be used for getting the proper servername?

| city continent feature_1 ...
|--------------------------------------------------
0 | Barcelona Europe
1 | Stockholm Europe
2 | New York America
3 | Nairobi Africa
4 | Tokyo Asia
The first approach was to simply load this data as:
// Insert city nodes
USING PERIODIC COMMIT 1000
LOAD CSV WITH HEADERS FROM 'file:///city_data.csv' AS row
MERGE (city: City {name: row.city})
Next step was to incorporate the continent information, so I could have nodes of different colors. This means having two labels for each node, which is something I am not sure how to do. Anyway, for the moment I decided to simply have one label instead, which contained the continent information. Since this information is within the CSV file I believe apoc.create.node tool is the way to go. Hence, inspired by How to use apoc.load.csv in conjunction with apoc.create.node I tried the following:
CALL apoc.load.csv('file:///city_data.csv') YIELD row
CALL apoc.create.node(['row.continent'], {name:['row.continent']}) YIELD node
RETURN count(*)
This does not raise any error, but it does something different from what I was thinking of. It basically sets the column name ("row.continent") itself as the label...

Say you have a survey on your website and an insert query for the database, how would you insert the name of the user answered the survey using
1) C#
2) Javascript
given that the user logs into the website with a password and an email. there's a different form for login page and another for index.
B.
Given that your website has an option for print\send email to client, How whould you insert the name of the user that performed the action (pressed print / send email) using
1) C#
2) Javascript.

nav li:first-child a{
padding-left:0px;
}
It's because you start list all the li and go to the element that want to change.
In your code nav a:first-child:hover you try to list the a and as you can see on each li are just one a, that is because all the a changes with the first-child.

Whatever the integral is, we would need to integrate it into a constant unit vector along the line of integration. So one way of doing this is to convert into Cartesian coordinates since the unit vectors then don't depend on position. I'm not sure why the first part of the claim is true, though.

I know I can calculate this using the formula, however I am wondering if there is a quick way to output the probabilities and append them to my DF.
I am running the following model:
attach(non.part.2)
y <- cbind(E)
x1 <- cbind(tech.ems, med.com, tech.nonemerg)
probit <- glm(y ~ x1, family = binomial (link = "probit"))
summary(probit)
I am running several models, so it would be nice to be able to have R spit out the probabilities and allow me to name them in my DF(non.part.2) - something like p_x1 - so that I can run summary stats on the various models later.
Any help is much appreciated!

General resources of <PERSON>'s concept can easily be found on the internet, so I won't even start listing resources. Specifically for Math, I find the conception of cognitive rigor by <PERSON> pretty enlightening.

I'm assuming that you are going to convert to .jpg format and store all the files in a ./output/ directory. My script would look like this:

for i in `find . -type f \( -iname *.jpg -o -iname *.jpeg -o -iname *.png -o -iname *.gif -o -iname *.bmp \)`
do
j=$(($j+1))
convert $i output/`printf "%06X" $j`.jpg
done
This script will start a counter '$j' from 0.
Then it finds all files that are of type file (rather than directories or symlinks or other such things) and match your specified extensions in a case insensitive manner. The ( ) groups a series of items that are each joined together with a -o OR specifier for the find command.
We use a for loop to go over all the found files noting them with $i.
Inside the loop, I increment the counter $j.
Then I convert the filename as I found it to .jpg and output into the ./output/ directory.
The hex numbered filename is 0 padded out to six digits using a printf command.

Godaddy doesn't support deleting an individual record.
From their support on the question whether it was possible to delete a record:
Dear Sir/Madam,
This API call does not exist at this time and it is something on our backlog to build out but there is no ETA to have it created. Current you can use the Put endpoint on the record type to replace all but the one you do not want to keep or you may go into our UI to remove it that way.
See their api documentation for what is available (at this date July 2020).
However, what you can do is replace all the existing records with a new set.
So suppose you have three A records with subdomain SD1, SD2 and SD3 and you want to remove SD2. You could sent an update command using:
curl -X PUT "https://api.godaddy.com/v1/domains/<yourdomain>/records/A" -H "accept: application/json" -H "Content-Type: application/json" -H "Authorization: <yourAPIKEY>" -d "[ { \"data\": \"<IP for SD1>\", \"name\": \"SD1\", \"ttl\": 3600 }, { \"data\": \"<IP for SD3>\", \"name\": \"SD3\", \"ttl\": 3600 }]"
Which will result in two A records one for SD1 and one for SD3. As long as you have at least one recordtype left (this also works for MX, MS, TXT) you will be able to remove others.
If you want to remove the last you have to go back to the Godaddy GUI, unfortunately.

If your game is written by OpenGL, Angle can help you translate it into several backends, such as Vulkan, D3D.
And if you are designing a game from the beginning, you may try writing it by Dawn. Dawn is similar to a middle layer, if your game is based on dawn, it can make sure your game runs smoothly on the different backends.

STRINGS BEFORE
imported txt file contents (a list of string values)
STRINGS AFTER
Where both the preceding and following STRINGS are already defined, and everything is written to a new file!
My end goal, is so that when i import a txt file (containing a list) and run the code, it then is printed to a new file with pre-defined strings added before and after the imported txt file's list.
My code right now is as follows:
text_file = open(r"text_file path", "r")
lines = text_file.read().split(',')
lines.insert(0, "String Values Before")
lines.insert("String Values After")
text_file.close()
lines.write("new_file.txt", "w+")
The problem now is that I am inserting to the list, whereas I want the strings to be separate to the list!
I've been able to produce what I want the written file to look like in the console with this code here:
FIRMNAME = "apple"
FILETYPE = "apple"
REPLYFILENAME = "apple"
SECMASTER = "apple"
PROGRAMNAME = "apple"
text_file = open(r"textfile path", "r+")
lines = text_file.readlines().split('\n')
print(("START-OF-FILE \nFIRMNAME= ") + FIRMNAME)

The objective is to then compare both xls files for differences and print out any differences to a third excel file.
However, when the differences are printed they include any entry with an integer above 999, as any integer from my converted csv file is treated as a string instead of an integer. Therefore it treats a value such as 1,200 (in my converted xls file) differently from 1200 (in my converted txt file) due to the comma in the converted csv excel file.
My question is: Is there a way to convert the string interpreted integers, back to being interpreted as integers? Otherwise, is there a way to delete all commas from my xls files? I have tried the usual dataframe.replace methodology and it is ineffective.
Below is my code:
#import required libraries
import datetime
import xlrd
import pandas as pd
#define the time_handle function to name the outputted excel files
time_handle = datetime.datetime.now().strftime("%Y%m%d_%H%M")
#identify XM1 file paths (for both csv origin and excel destination)
XM1_csv = r"filepath"
XM2_excel = r"filepath" + time_handle + ".xlsx"
#identify XM2 file paths (for both txt origin and excel destination)
XM2_txt = r"filepath"
XM2_excel = r"filepath" + time_handle + ".xlsx"
#remove commas from XM1 excel - failed attempts
#XM1_excel = [col.replace(',', '') for col in XM1_excel]
#XM1_excel = XM1_excel.replace(",", "")
#for line in XM1_excel:
#XM1_excel.write(line.replace(",", ""))
#remove commas from XM1 CSV - failed attempts
#XM1_csv = [col.replace(',', '') for col in XM1_csv]
#XM1_csv = XM1_csv.replace(",", "")
#for line in XM1_csv:
#XM1_excel.write(line.replace(",", ""))
#convert the csv XM1 file to an excel file, in the same folder
pd.read_csv(XM1_csv).to_excel(XM1_excel)
#convert the txt XM2 file to an excel file in the same folder
pd.read_csv(XM2_txt, sep="|").to_excel(XM2_excel)
#confirm XM1 filepath
filepath_XM1 = XM1_excel
#confirm XM2 filepath
filepath_XM2 = XM2_excel
#read relevant columns from the excel files
df1 = pd.read_excel(filepath_XM2, sheetname="Sheet1", parse_cols= "H, J, M, U")
df2 = pd.read_excel(filepath_XM1, sheetname="Sheet1", parse_cols= "C, E, G, K")
#remove all commas from XM1 - failed attempts
#df2 = [col.replace(',', '') for col in df2]
#df2 = df2.replace(",", "")
#for line in df2:
#df2.write(line.replace(",", ""))
#merge the columns from both excel files into one column each respectively
df4 = df1["Exchange Code"] + df1["Product Type"] + df1["Product Description"] + df1["Quantity"].apply(str)
df5 = df2["Exchange"] + df2["Product Type"] + df2["Product Description"] + df2["Quantity"].apply(str)
#concatenate both columns from each excel file, to make one big column containing all the data
df = pd.concat([df4, df5])
#remove all whitespace from each row of the column of data
df=df.str.strip()
df=["".join(x.split()) for x in df]
#convert the data to a dataframe from a series
df = pd.DataFrame({'Value': df})
#remove any duplicates
df.drop_duplicates(subset=None, keep=False, inplace=True)
#print to the console just as a visual aid
print(df)
#output_path = r"filepath"
#print the erroneous entries to an excel file
df.to_excel("XM1_XM2Comparison" + time_handle + ".xls")
Also, I realize the XM1 and XM2 file names with regards to df1 and df2 is a bit confusing, but I simply renamed my files. It makes sense in terms of the files and where they belong in the code!
Thank You

This means it's not read-only but the documentation says to treat it as read-only.
Rephrased question: What happens when you try to assign to an assignable property that the documentation says to treat as read-only?
Short answer: Does it matter?
Long answer: Without the source, it's very hard to tell. You could use ILSpy to debug it but the short answer still applies.

| 2 | Fish |

fruits:
| fruid_id | fruit_label |

| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| 3 | 4 |
| 4 | 1 |
Each animal can like multiple fruits and each fruit can be liked by multiple animals, so I have a many-to-many relationship between the animals and fruits. This relationship is described using the third table called likes.
I am trying to determine which animals don't like bananas. In order to do so, I wrote this statement:
SELECT animal_id, animal_label
FROM animals
WHERE animal_id NOT IN (
SELECT animal_id
FROM likes
WHERE fruit_id = 4)
That successfully returns the elephant, fish and snake, but not the monkey, because the monkey likes bananas.
However, I was wondering if this statement could be rewritten using a join. This is what I tried so far:
SELECT animal_id, animal_label
FROM animals
LEFT OUTER JOIN likes ON animals.animal_id = likes.animal_id
WHERE fruit_id <> 4 OR fruit_id IS NULL
This time, all four animals are returned. The issue here is that because the monkey also likes peanuts, this statement will return it even though it likes bananas. Is there any way to solve this that would be better than my solution using the subquery?

Tarantulas are mostly pretty harmless but we don't eat them possibly because they resemble other highly venomous species like the brown recluse. Eight legs, lots of eyes, etc.
Kind of related to what causes batesian mimicry. Milk snakes (non venomous) evolved to look a lot like coral snakes (highly venomous) so they are less likely to get eaten because predators that like eating brightly colored snakes tend to die a percentage of the time.

Why is this the case? I understand that when the clarinet is overblown the pitch goes up by a 12th, not an octave, which extends the range, but I don't understand the physics of how it can play so much lower than the soprano sax. It seems like it could be partly to do with the size of the mouthpiece (soprano sax has a much smaller mouthpiece) or possibly to do with the bore shape, but I'm not really sure whether any of these reasons are right.

Not just because, to many, the point of science and mathematics is understanding and appreciating the beauty of reality, but also because it might become practical in the future! I doubt the people who worked on number theory foresaw crytography, for instance, or the esoteric probability theory making its way into machine learning now.
Also, I think tying together distant theorems is a practical application in some sense. Or at least an educational one for practitioners who might be trying to understand something, and realize something useful based on your theorem tying it to something else.
As the other answer says, I think it makes sense as long as you make it coherent with the rest of the paper!

I try to log message into file and insert data into db during the execution of OnApplicationEndRequest(object sender, EventArgs e) method of my custom HTTP module (BasicAuthHTTPModule.cs) in my ASP.NET Web API application. My custom HTTP module follows this structure (with modification in OnApplicationEndRequest(object sender, EventArgs e) ) => https://learn.microsoft.com/en-us/aspnet/web-api/overview/security/basic-authentication#basic-authentication-with-custom-membership.
I have investigated 2 cases where the application behave differently and I don't know why...
case 1)
When I run this project from Visual Studio, database insertion is performed fine, but file insertion isn't performed at all = nothing happens... Btw I am able to log into file from Controller, but no from HTTP Module. So it is not possible to log into file from HTTP Module class?
case 2)
When I host my ASP.NET WEB API on remote server and I consume the API from my local PC's console application, database insertion is not performed, neither file insertion. So nothing at all is performed in this case. It looks like that my custom HTTP module is not being hit in this case...
Here are my code snippets:
BasicAuthHttpModule.OnApplicationEndRequest(object sender, EventArgs e)

insert log into db
insert log into file

We had the same type of issue you describe, iOS 9 had no issues but iOS 10 would place a random length of the barcode into the field and split the remaining part to another field.
Note the below is tested on iPad 4 iOS 10.3.2 and your results may vary. This hasn't been tested thoroughly, only about 100 barcodes or so and mostly with the Koamtec since that is what was causing us the most trouble.
The scanners we use (Koamtac KDC400 and Symbol LS/LI-4278) both have a setting to slow down the transmission of the bar code data. When I set them to longer delays the barcodes come through fine.
For the KDC you are looking for "HID Character Delay = 50msec" (I find 100 is a good one too but it is very slow)
For Symbol LS/LI you want "HID Keyboard Keystroke Delay" / "Long Delay (40 msec).
For other brands/models there is a good chance the manual will have a similar code.
In your linked post you mention Opticon Scanners, I don't have any of those but taking a very quick glance at the manual it might be called "Intercharacter delay" for that brand.
If this works for you or if you came up with a different workaround I would love to hear it.

So I made some sample data to try and figure it out but now I am stuck.
I am shooting for doing it in php/mysql so I can have web pages as the output but what I need help with is the db design and the sql to make the "see also" bit work right. I am thinking I need another table that somehow connects all of them but I’m not sure how to do that.
Example Table Fields:
Table 1: Place
PlaceID PK
PlaceName
PlaceCityName
PlaceStateName
PlaceSeeAlso
Table 2: Person
PersonID PK
PersonName
PersonJob
PersonSeeAlso
Table 3: Thing
ThingID PK
ThingName
ThingSeeAlso
Example data:
Places Table
00
PlaceA
Philadelphia
PA
PersonA, PersonB, ThingA, PlaceC
01
PlaceB
Philadelphia
PA
PersonA, ThingB, PlaceA, PlaceC
02
PlaceC
Philadelphia
PA
PersonA, ThingB, ThingC, PlaceA
Person Table
00
PersonA
Worker
ThingB, PlaceA, PlaceC
01
PersonB
Worker
PersonA, PersonC, ThingB, PlaceA, PlaceC
02
PersonC
Boss
PersonB, ThingB, ThingC, PlaceA, PlaceB
Things Table
00
ThingA
PersonA, PlaceC
01
ThingB
PersonB, PlaceB, ThingC
02
ThingC
PersonA, PersonC, PersonE, PlaceC, ThingA
So for example say you did a search for a person, place or thing, let’s say "PersonC", the output on a webpage/window in my program/whatever would be:
Name: PersonC
City: Philadelphia
State: PA
Description: Boss
See Also: PersonA, ThingB, ThingC, PlaceA
All of the things under "See Also" should be clickable to bring up the matching record. So in the above example you click "ThingC" you would get
Name: ThingC
See Also: PersonA, PersonC, PersonE, PlaceC, ThingA
All of the things under "See Also" should be clickable etc etc etc.
Just a reminder I am in need of help with how to structure the DB and maybe some of the sql as far as the See Also part is concerned, not the making things clickable on a webpage etc.

and invoking .stop() before animations. (Otherwise multiple of those animations will be done since scroll event is triggered multiple times. Those animations end up in the queue of animations. By just invoking animate you put your animation in this queue (and it will be done only AFTER all the other animations are done). By calling stop() you can empty this queue and thus immediately let your animation be done )
Look at http://jsfiddle.net/371fqnbo/2/
However your code contains some redundancies which could be eliminated.

I got the following code working properly with box2d v2.2.1, cocos2D v2.0.0 using Xcode v4.5.2 (here I assume I have a pointer to a b2Body named 'body' with only one fixture, i.e., I don't iterate over all fixtures on the body):
b2Fixture *fix = body->GetFixtureList();
b2Filter filter = fix->GetFilterData();
filter.groupIndex = -1*kPlayerGroupIndex;
fix->SetFilterData(filter);
In the above code I prevent 'body' from colliding with my player body which also has the same groupIndex value, i.e., -1*kPlayerGroupIndex, where kPlayerGroupIndex is a positive integer constant. Any bodies with this negative groupIndex never collide with one another. You could also update the categoryBits or maskBits accordingly to prevent collisions.
GetFilterData(&filter) and SetFilterData(&filter) returned errors for me given the version numbers I quoted above.

When the lift reaches the upper end of translation along the prismatic joint, it appears to stop. However, when another body is sitting on top of the lift and it reaches the upper end of translation, the body on top the lift begins to "bounce" around as if the lift is still applying a force. (I believe this is exactly what is happening, i.e., the lift's body doesn't translate any further along the prismatic joint, but the prismatic joint's motor is still cranking away and applying upward forces to the body).
I initially resolved this issue by manually setting the prismatic joint's motor speed to 0.0 when the upper end of translation was reached. In my main game loop, i.e., the function that gets called at the frame rate ("tick:" in Box2D or "update:" in Cocos2D), I inserted the following (I'm using Objective-C here and kLiftJointValue is an arbitrary integer constant):
// Iterate over all joints (used to prevent upper end oscillations from psimaticJoints on lifts)
for (b2Joint* j = world->GetJointList(); j; j = j->GetNext())
{
if ((int)(j->GetUserData()) == kLiftJointValue) // check to see if lift is at upper end of translation
{
CGFloat currentTranslation = ((b2PrismaticJoint*)j)->GetJointTranslation();
CGFloat lowerLimit = ((b2PrismaticJoint*)j)->GetLowerLimit();
CGFloat upperLimit = ((b2PrismaticJoint*)j)->GetUpperLimit();
b2Body *bodyA = j->GetBodyA();
b2Body *bodyB = j->GetBodyB();
BOOL notStopped = (bodyA->GetType() == b2_dynamicBody || bodyB->GetType() == b2_dynamicBody);
if (fabsf(currentTranslation - lowerLimit) <= 0.01*(upperLimit - lowerLimit) && notStopped )
{
CCLOG(@"Stopping platform");
(j->GetBodyA())->SetType(b2_staticBody);
(j->GetBodyB())->SetType(b2_staticBody);
((b2PrismaticJoint*)j)->SetMotorSpeed(0.0);
}
}
}
The above code simply iterates over all joints in the world and looks for those tagged appropriately, and if the body has translated to within 1% of the maximum translation allowed then the moving body is changed to static and the motor is disabled by setting the motor speed to 0. You could also use Box2D collision detection and set the joint's motor speed to 0 that way...
I then realized that the best way to implement this lift (without disturbing anything sitting on top of the lift) was to slowly decelerate the prismatic joint's motor speed gradually. This is how I did it:
// Iterate over all joints (used to prevent upper end oscillations from psimaticJoints on lifts)
for (b2Joint* j = world->GetJointList(); j; j = j->GetNext())
{
if ((int)(j->GetUserData()) == kLiftJointValue) // check to see if lift is at upper end of translation
{
CGFloat currentTranslation = ((b2PrismaticJoint*)j)->GetJointTranslation();
CGFloat lowerLimit = ((b2PrismaticJoint*)j)->GetLowerLimit();
CGFloat upperLimit = ((b2PrismaticJoint*)j)->GetUpperLimit();
b2Body *bodyA = j->GetBodyA();
b2Body *bodyB = j->GetBodyB();
BOOL notStopped = (bodyA->GetType() == b2_dynamicBody || bodyB->GetType() == b2_dynamicBody);
if (fabsf(currentTranslation - lowerLimit) <= 0.25*(upperLimit - lowerLimit) && notStopped)
{
// Get current motor speed and update
CGFloat currentSpeed = ((b2PrismaticJoint*)j)->GetMotorSpeed();
CGFloat newSpeed;
if (currentSpeed < 0.0)
{
if (fabsf(currentTranslation - lowerLimit) <= 0.01*(upperLimit - lowerLimit) && notStopped )
{
CCLOG(@"Stopping platform");
(j->GetBodyA())->SetType(b2_staticBody);
(j->GetBodyB())->SetType(b2_staticBody);
((b2PrismaticJoint*)j)->SetMotorSpeed(0.0);
}
else
{
CCLOG(@"Decelerating: speed=%f", currentSpeed);
newSpeed = 0.95*currentSpeed;
}
}
else if (currentSpeed > 0.0)
{
CCLOG(@"Accelerating: speed=%f", currentSpeed);
newSpeed = 1.05*currentSpeed;
if (newSpeed > 20.0)
newSpeed = 20.0;
}
// update motor speed
((b2PrismaticJoint*)j)->SetMotorSpeed(newSpeed);
}
}
}
You'll need to play with the various constants (especially the constants 0.95 and 1.05) since they are fine-tuned for specific motor properties (maxMotorForce = 1000 and motorSpeed = 20 in my case).
Of course elsewhere in my project I have timers running which reset the lift body and joint motor properties as needed (to make it travel up, then back down by reversing the joint's motor speed with a positive value).
I didn't implement the acceleration/deceleration technique when the lift was translated near the other (bottom) limit since I didn't care about stuff riding the lift being imparted forces in this direction when the lift stopped. However, the same approach as outlined above can be used to smoothly accelerate or decelerate as the lift leaves from or returns to the bottom...

Applying an x64 install image won't get you a USB disk that boots on x86 or ARM. Beyond that, it's probably more portable than (for example) SATA, because the USB controller software interface is highly standardized and only a handful of drivers need to be present (OHCI, EHCI, UHCI, xHCI) plus USB mass storage profile, no worries about BIOS setting for RAID mode that doesn't speak AHCI and needs proprietary drivers. I heard that getting such an install to stay activated if you move it around can be an issue. | bd5fbcf27446c07bb0d6b8165097ac75368fee38ad10d434e326e328020618e1 | ['1f48289910b2451795d9847cb571936b'] | `apt-get` refuses to remove anything, because the last kernel it tried to install didn't fit on `/boot`, leaving unmet dependencies. Those dependencies can't be installed due to lack of space, and *really* old kernels can't be installed, because of unmet dependencies in the global package list. :( |
