How to get value from previous field to new field | <p>Is there any way to call value from previous field to the new field by using trigger?
i have tried with following method and this method is working perfectly with first row but when i moved to second row it automatically copy data from "remaining" to "monthly" field:</p>
<pre><code>BEGIN
IF (:REMAINING IS NULL) THEN
:REMAINING=:MONTHLY-:FEE;
NEXT_ITEM;
:MONTHLY:=:REMAINING;
END IF;
END;

Event listeners overwriting one another? | <pre><code>function newMenu(items,results){
document.getElementById("menu").innerHTML = "";
for (var i = 0; i < items.length; i++) {
document.getElementById("menu").innerHTML += "<li>" + items[i] + "</li>";
document.getElementById("menu").childNodes[i].addEventListener("click",function(){document.write("foo")});
};
}
</code></pre>
<p>I am trying to use this code to generate a list and then give each of the list items a different function to be activated when they are clicked (right now I've just made them all write "foo" to test that the event listeners work). However, when I run this function, it will write all of the list content correctly (they're passed as an array into 'items').</p>
<p>My problem arises with the event listeners. Only the last list item's event listener works. That is to say, only when I click on the last li in the list does it execute document.write("foo"). I've tried changing the size of the items array and every time it's the last list item, regardless of length. Why might this be? Are the event listeners overwriting one another?</p> | 3 |
Print transaction status on TextArea | <p>I am developing a project which does the following :</p>
<p>1.truncate a temporary table T1. </p>
<p>2.insert some thousand rows into temporary table T1.</p>
<p>3.Execute a procedure which has some commit statements in it.</p>
<p>4.insert rows from table T1 to other identical table(with respect to structure) T2</p>
<p>5.Execute 2 more procedures.</p>
<p>Now i have made a swing UI which contains TextArea on which i want to print transaction status. Something like this</p>
<p>Reading Excel File..
Validating Excel File..
inserting entries into table T1.. and so on</p>
<p>I have made the following method to update status at each step.</p>
<pre><code>public void updateStatus(String message){
String temp = this.statusText.getText();
this.statusText.setText(temp + message + "\n");
}
</code></pre>
<p>Calling this method along with statements where i do</p>
<p><code>log.debug(message)</code> does the job for me ! However this complicates my code design. Every DAO Component now depends on this method. Can anyone suggest me a better design option.</p>
<p>Thanks in Advance !</p> | 3 |
OpenCover and GoogleTest - Complains missing PDBs | <p>The build I am currently working on uses Visual Studio 2008 (Professional) in a 32bit environment to compile. We have been using Google Test Framework to create unit test. We are trying to use OpenCover to report code coverage, and it returns </p>
<pre><code>"no results - no assemblies that matched the supplied filter were instrumented. this could be due to missing PDBs for the assemblies that match the filter. please review the output file and refer to the Usage guide (Usage.rtf)"
</code></pre>
<p>The Test executable did run as I saw the result displayed on the console. The PDB is at the same directory as the Google Test Executable. The command that I have used:</p>
<pre><code>OpenCover.Console.exe -target:<Full Path Unit Test Executable> -targetdir:<Directory of the exeutable which also includes the PDB> -output:cover.xml
</code></pre>
<p>Note: The directory and exeutable do not contains space, so I have omitted quotation, but I have tried using it or without, and the result is the same</p>
<p>Things I have tried:</p>
<ul>
<li>I have explicitly registered the OpenCover.Profile.dll </li>
<li>I have used -register:user argument</li>
<li>I have tried to use -targetargs:"/noshadow" (and the noisolation), which I believe these are specific to MSTest and NUnit, but not for GoogleTest</li>
<li>I have tried omitting the targetdir parameter</li>
<li>I have installed the VS 2010 redistribution </li>
</ul>
<p>All of them yield the same result. I am able to run the sample that comes with the installation. </p>
<p>Has anyone successfully integrate Google Testing Framework with OpenCover? Or is there specific compilation setup on the project? (I have turned on/off profiling, and it didn't make a difference)</p>
<p>Thanks!</p> | 3 |
Works in localhost but not when uploaded on server | <p>I have a problem...
When I use</p>

module array output | <p>I'm writing a module to add functionality to the FlagShihTzu gem.</p>
<p>Basically it goes through the flags and outputs the keys for the ones assigned to the object. It's working, but I also want to be able to use a block in the view to do things with the output.</p>
<p>The problem is that it's outputting both the array from the module and the output from the block in the view.</p>
<pre><code>module AwesomeFlags
def my_flags(column = nil)
a = self.flag_mapping
if column.nil?
c = a.values.map {|var| var.keys}.flatten
else
b = a[column]
c = Array.[](b.keys).flatten
end
c.map {|var| self.send(var) ? "#{var.to_s} " : nil}.compact!
end
end
</code></pre>
<p>In the view:</p>
<pre><code>= book_offer.my_flags.each do |flag|
= flag.titleize
</code></pre>
<p>What I get is:</p>

Is it safe to reuse a conduit? | <p>Is it safe to perform multiple actions using the same conduit value? Something like</p>
<pre><code>do

something $$ sink
somethingElse $$ sink

Variable sized packet | <p>I am trying to define a packet whose length is determined during an ns-3 simulation (think of it as a packet sent on the downlink containing schedule information whose length depends on the number of nodes in the network which can join/leave the network during simulation).

apply parent's hover to jquery ui autocomplete child | <p>I'm in a similar situation a my other problem <a href="https://stackoverflow.com/questions/16195454/prevent-datepicker-from-triggering-parent-mouseleave/16196098?noredirect=1#16196098">prevent datepicker from triggering parent mouseleave</a>, but that solution doesn't seem to apply to jQuery UI autocomplete.</p>
<p>How can the hover also apply to autocomplete children? In other words, if one <code>mouseenter</code>s on an autocomplete suggestion, <code>#hoverMe</code> should stay open.

Resizing lots of images via PHP, keeping aspect and not using all my RAM? | <p>I have a problem that I thought was easily solved, but is turning out a little more difficult than anticipated.</p>
<p>I am working on a site which someone can upload images for a product, and it resizes them twice (500x500 and 150x150) on the fly. I am trying to keep the aspect ratio, for example if I had 600x500 image it would resize to 500x417 and 150x125.</p>
<p>I have found (lots) of code that does this, such as <a href="http://www.white-hat-web-design.co.uk/blog/resizing-images-with-php/" rel="nofollow">this class</a>, however I always run into memory issues. I think the class isn't unloading/destroying the temporary images after resizing.</p>
<p>I had the host upgrade my memory-limit to 64M from 32, however I run out of memory later. I'm stuck with PHP 5.2.13 as well, so no garbage collector for me.</p>
<p>My PHP is fairly new, so it's very alien to me how classes work, otherwise I would try adding the imagedestroy() function where required. I fiddled with the linked class for hours without success.</p>
<p>Can anyone either:</p>
<p>-Point me in the direction of a magic class that keeps aspect as well as unloading/destroying temporary images after resizing is complete, to keep RAM usage under control?</p>
<p>-Give me some (much needed!) guidance on where and how I could modify a class (such as the one posted) to destroy temporary images.</p>
<p>-Tell me if I'm going around this extremely wrong?</p>
<p>Oh, and I had the WideImage class working at one point, and it worked great, then suddenly stopped. I spent hours trying to fix it with no success.</p>
<p>My PHP install has GD, but not ImageMagick.</p>
<p>Thanks!</p> | 3 |
available CRAN vignettes | <p>There's the <code>available.packages()</code> function to list all packages available on CRAN. Is there a similar function to find all available vignettes? If not how would I get a list of all vignettes and the packages they're associated with?</p>
<p>As a corner case to keep in mind the <code>data.table</code> package has 3 vignettes associated with it. </p>

Arranging elements with a variable size on a fixed canvas | <p>Input:

<p>(note that this example is pure fiction)</p>
<ol>
<li>Top level community name (e.g. Stack Overflow USA, Stack Overflow BEL)</li>
<li>Subcommunity (e.g. stackOverflow.com/r/USA/CSS and stackOverflow.com/r/BEL/JSON)</li>
<li>Owner(s) of the subcommunity (e.g. Frank) </li>
</ol>
<p>Depending on the situation and the point in time, the amount of top level communities, that have a variable number of subcommunities are each owned by a variable number of owners. And, each top level community can also have one or more owners.</p>
<p>(input) table example:</p>
<pre><code>SO USA, , Phil

SO USA, JSON, Marc
SO BEL, CSS, Marieke
SO BEL, CSS, Francis

Issues with creating a new isolated scope in factory | <p>I'd like to know what the consequences / issues of creating a new isolated scope in a factory are, by doing <code>$rootScope.$new()</code></p>
<p>I'm trying to allow the user of my library to do something like <code>$cordovaPush.$on('notReceived')</code>, rather than using <code>$rootScope.$on('...')</code> (even though it may be pointless to do this). I've seen other comments about memory leaks and various other issues with creating a new scope, but I haven't found any proof or real convincing arguments as to why this should not be done.</p>
<p>Here's some code as a reference to what I'm doing:</p>
<pre><code>.factory('$cordovaPush', ['$q', '$window', '$rootScope', '$timeout', function ($q, $window, $rootScope, $timeout) {
var $cordovaPush = $rootScope.$new(true);
$cordovaPush.onNotification = function (notification) {
$timeout(function () {
$cordovaPush.$broadcast('notificationReceived', notification);
});
};
$cordovaPush.register = function (config) {
...
};
$cordovaPush.unregister = function (options) {
...
};
$cordovaPush.setBadgeNumber = function (number) {
...
};
return $cordovaPush;
}]);

<p>The page that shows the items is used quite a lot by our customer and last Tuesday they reported some problems that the data wasn't showing or took a long time to show up.
Having looked at the cloud function logs at that time, we see a lot of timeouts followed by a few of these errors:</p>
<blockquote>
<p>CloudSQL warning: your action is needed to update your function and avoid potential disruptions. Please see <a href="https://cloud.google.com/functions/docs/sql#troubleshooting" rel="nofollow noreferrer">https://cloud.google.com/functions/docs/sql#troubleshooting</a> for additional details: googleapi: Error 429: Quota exceeded for quota group 'default' and limit 'Queries per user per 100 seconds' of service 'sqladmin.googleapis.com' for consumer 'project_number:[some number]'., rateLimitExceeded</p>
</blockquote>
<p>I'm not entirely sure if this is the cause of the issue, but it does seem like something we should do something about anyway.
As I understand it, we can send 300 queries per user per 100 seconds to the MySQL server. So about 3 per second. The cloud function itself only sends 2 queries to the server. One to retrieve the data for the current page with the applied filters and another one to get a total record count.
However, we don't send any user info when performing the query. So I think that if 150 users each trigger the callable, 300 queries will be performed and counted towards the quota as if they were done by a single user. Because it's a server, the cloud function, that actually performs the query. The error also mentions the quota group 'default'.</p>
<p>The following page tells me that I should be able to pass a 'quotaUser' parameter to specify a specific user that requests should count towards for the quota.</p>
<p><a href="https://cloud.google.com/apis/docs/capping-api-usage#limiting_requests_per_second_per_user" rel="nofollow noreferrer">https://cloud.google.com/apis/docs/capping-api-usage#limiting_requests_per_second_per_user</a></p>
<p>However... I have no idea how to pass that parameter with our queries. I've read something that this parameter can be used in the url parameters or in the headers, but we are using the Node.js mysql package to perform these queries, and I don't know how to tell it to send this parameter.
This is the guide we followed to set up the mysql connection. We are using the same mysql package.</p>
<p><a href="https://cloud.google.com/sql/docs/mysql/connect-functions#node.js" rel="nofollow noreferrer">https://cloud.google.com/sql/docs/mysql/connect-functions#node.js</a></p>
<p>I would think that if a GCP guide tells us to use that mysql package, it should also somehow be possible to specify this quotaUser.</p>
<p>If anyone can help me out with this, it would be greatly appreciated. I'm a bit stuck and can't find any documentation or examples on how to pass this parameter for MySQL queries.</p>
<p>This is how we connect to the MySQL server:</p>
<pre><code>import { config } from '../config';
import { createConnection, Connection, ConnectionConfig } from 'mysql';
export function connectToMySQLDatabase(): Connection {
const connectionName: string | undefined = process.env.INSTANCE_CONNECTION_NAME || `${config.firebaseProjectId}:${config.mysqlConfig.regionId}:${config.mysqlConfig.instanceId}`;
const dbUser: string | undefined = process.env.SQL_USER || config.mysqlConfig.user;
const dbPassword: string | undefined = process.env.SQL_PASSWORD || config.mysqlConfig.password;
const dbName: string | undefined = process.env.SQL_NAME || config.mysqlConfig.databaseName;
const mysqlConfig: ConnectionConfig = {
user: dbUser,
password: dbPassword,
database: dbName,
dateStrings: true,
socketPath = `/cloudsql/${connectionName}`;
};
return createConnection(mysqlConfig);
}
</code></pre>
<p>And how we perform a query:</p>
<pre><code>exports.itemQuerySQL = functions
.region(config.region)
.runWith({
timeoutSeconds: 60,
memory: '1GB'
})
.https
.onCall(async (request: GetItemsRequest, context) => {
const mysqlConnection: Connection = connectToMySQLDatabase();
try {
return await queryItems(request, mysqlConnection);
} catch (error) {
throw error;
}
finally {
mysqlConnection.end();
}
});
async function queryItems(request: GetItemsRequest, mysqlConnection: Connection): Promise<CallableQueryResponse<string>> {
let query = '';
let values = [];
// Removed a bunch of code irrelevant to the issue that builds up the query and values array.
const results: any[] = await performQuery(mysqlConnection, sqlQuery, sqlQueryValues);
return {
results: results,
// Some other properties
};
}
async function performQuery(mysqlConnection: Connection, query: string, values?: (string | string[] | number | null)[]): Promise<any> {
return new Promise((resolve: (value?: unknown) => void, reject: (reason?: any) => void): void => {
mysqlConnection.query(query, values, (error: MysqlError, results: any) => {
if (error) {
return reject(error);
} else {
return resolve(results);
}
});
});
}
</code></pre>
<p>Besides the code that constructs the query itself, I also left out most of the error handling to keep these examples small.</p> | 3 |

Use of markdown in loops in Jupyter notebooks | <p>I have a Python program (more exactly a suite of programs) which I want to add more markdown comments in order to be train/document using them. In some of them the comments would naturally be placed go inside long loops.</p>
<p>My understanding is that if you split the loop by inserting a markdown cell the notebook will not execute the loop, since it sees the end of the cell as being the end of an executable block.</p>
<p>Is there a way round this? If so then what strategies do people adopt in such circumstances. Obviously, heavy standard-format Python commenting within the code is one option, but rather seems to defeat the purpose of Jupyter particularly if the comments need to be fairly detailed.</p> | 3 |

How to add interleaving rows as result of sort / groups? | <p>I have the following sample input data:</p>
<pre><code>import pandas as pd
df = pd.DataFrame({'col1': ['x', 'y', 'z'], 'col2': [1, 2, 3], 'col3': ['a', 'a', 'b']})
</code></pre>
<p>I would like to sort and group by <code>col3</code> while interleaving the summaries on top of the corresponding group in <code>col1</code> and get the following output:</p>
<pre><code> col1 col2
0 a 3
1 x 1
2 y 2
3 b 3
4 z 3
</code></pre>
<p>I can of course do the part:</p>
<pre><code>df.sort_values(by=['col3']).groupby(by=['col3']).sum()
col2
col3
a 3
b 3
</code></pre>
<p>but I am not sure how to interleave the group labels on top of <code>col1</code>.</p> | 3 |
How to pass array or arraylist by intent which has unserializable data? | <p>What I want to do is passing DataModel array between Activity by Intent.</p>
<p>DataModel class has Bitmap object and FirebaseVisionLabel object. I found many sites to implement this. </p>
<p>Many people said that DataModel class should implements Serializable or Parceable interface to pass <code>DataModel[]</code> or <code>ArrayList<DataModel></code>.</p>
<p>So I tried, but the real problem was FirebaseVisionLabel class cannot be serializable. Also, I cannot modify that class because it is firebase library.</p>
<p>How can I pass DataModel array by intent??</p>

Using CUDA atomicInc to get unique indices | <p>I have CUDA kernel where basically each thread holds a value, and it needs to add that value to one or more lists in shared memory. So for each of those lists, it needs to get an index value (unique for that list) to put the value.</p>
<p>The real code is different, but there are lists like:</p>
<pre><code>typedef struct {
unsigned int numItems;
float items[MAX_NUM_ITEMS];
} List;
__shared__ List lists[NUM_LISTS];
</code></pre>
<p>The values <code>numItems</code> are initially all set to 0, and then a <code>__syncthreads()</code> is done.</p>
<p>To add its value to the lists, each thread does:</p>
<pre><code>for(int list = 0; list < NUM_LISTS; ++list) {
if(should_add_to_list(threadIdx, list)) {
unsigned int index = atomicInc(&lists[list].numItems, 0xffffffff);
assert(index < MAX_NUM_ITEMS); // always true
lists[list].items[index] = my_value;
}
}
</code></pre>
<p>This works most of the time, but it seems that when making some unrelated changes in other parts of the kernel (such as not checking asserts that always succeed), sometimes two threads get the same index for one list, or indices are skipped.
The final value of <code>numSamples</code> always becomes correct, however.</p>
<p>However, when using the following custom implementation for <code>atomicInc_</code> instead, it seems to work correctly:</p>
<pre><code>__device__ static inline uint32_t atomicInc_(uint32_t* ptr) {
uint32_t value;
do {
value = *ptr;
} while(atomicCAS(ptr, value, value + 1) != value);
return value;
}
</code></pre>
<p>Are the two <code>atomicInc</code> functions equivalent, and is it valid to use <code>atomicInc</code> that way to get unique indices?</p>
<p>According the the <a href="https://docs.nvidia.com/cuda/cuda-c-programming-guide/#atomic-functions" rel="nofollow noreferrer">CUDA programming guide</a>, the atomic functions do not imply memory ordering constraints, and different threads can access the <code>numSamples</code> of different lists at the same time: could this cause it to fail?</p>
<p><strong>Edit:</strong></p>
<p>The real kernel looks like this:</p>
<p>Basically there is a list of <em>spot blocks</em>, containing <em>spots</em>. Each <em>spot</em> has XY coordinates (<em>col</em>, <em>row</em>). The kernel needs to find, for each spot, the spots that are in a certain window (col/row difference) around it, and put them into a list in shared memory.</p>
<p>The kernel is called with a fixed number of warps. A CUDA block corresponds to a group of <em>spot blocks</em>. (here 3) These are called the <em>local</em> spot blocks.</p>
<p>First it takes the spots from the block's 3 spot blocks, and copies them into shared memory (<code>localSpots[]</code>).
For this it uses one warp for each spot block, so that the spots can be read coalesced. Each thread in the warp is a spot in the local spot block.
The spot block indices are here hardcoded (<code>blocks[]</code>).</p>
<p>Then it goes through the <em>surrounding</em> spot blocks: These are all the spot blocks that may contain spots that are close enough to a spot in the <em>local spot blocks</em>. The surrounding spot block's indices are also hardcoded here (<code>sblock[]</code>).</p>
<p>In this example it only uses the first warp for this, and traverses <code>sblocks[]</code> iteratively. Each thread in the warp is a spot in the surrounding spot block.
It also iterates through the list of all the local spots. If the thread's spot is close enough to the local spot: It inserts it into the local spot's list, using <code>atomicInc</code> to get an index.</p>
<p>When executed, the printf shows that for a given local spot (here the one with row=37, col=977), indices are sometimes repeated or skipped.</p>
<p>The real code is more complex/optimized, but this code already has the problem. Here it also only runs one CUDA block.</p>

<p>Each line is the output of one execution (the kernel is run multiple times). It is expected that indices appear in different orders. But for example on the third-last line, index 23 is repeated.</p>
<p>Using <code>atomicCAS</code> seems to fix it. Also using <code>__syncwarp()</code> between executions on the outer for-loop seems to fix it. But it is not clear why, and if that always fixes it.</p>

Client server authentication with self signed certificate - Curl is working but Apache HttpClient throws exception | <p>I'm trying to implement client and server authentication with Apache HTTPClient,
and to test it with a self signed certificate.
I've tried to follow several tutorials and answers to similar questions here but
with no success. I've tried to detail as much as possible all the steps that I've
been doing, hopefully someone can point out what I'm doing wrong:</p>

<pre class="lang-sh prettyprint-override"><code>curl: (60) SSL certificate problem: self signed certificate
More details here: https://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

How to import data from another package | <p>I have one package (say <code>testpackage1</code>) which contains a method called <code>readData()</code>.</p>
<p>This method reads a <code>test.data.rda</code> file that is placed in the data folder of <code>testpackage1</code> and after some operations, returns a data frame.</p>
<p>This is the only R file in <code>testpackage1</code>:</p>
<pre><code>#' Reads data and transforms it
#'
#' @return a data.frame
#' @export
#'
#' @examples my.df <- readData()
readData <- function() {
return(subset(test.data, x < 50))
}
initPackage <- function() {
test.data <- data.frame(x = seq(1, 100),
y = seq(101, 200))
devtools::use_data(test.data, overwrite = TRUE)
}
</code></pre>
<p>Calling the <code>initPackage</code> method creates the data frame and saves it as a .rda file in the data folder.</p>
<p>Now I have created a second package named <code>testpackage2</code>, that also has only one R file:</p>
<pre><code>#' Gets the data
#'
#' @import testpackage1
#' @export
#'
#' @examples hello()
hello <- function() {
print(testpackage1::readData())
}
</code></pre>
<p>I built both packages, then started a fresh R session and typed:</p>
<pre><code>> library(testpackage2)
> hello()
</code></pre>
<p>But I have this error:</p>
<pre><code>Error in subset(test.data, x < 50) : object 'test.data' not found
4. subset(test.data, x < 50) at hello.R#8
3. testpackage1::readData()
2. print(testpackage1::readData()) at hello.R#8
1. hello()
</code></pre>
<p>If I type <code>require(testpackage1)</code> before calling method <code>hello()</code>, then it works.</p>
<p>But I thought loading <code>testpackage2</code> would have automatically loaded its dependencies. I could add <code>require(testpackage1)</code> in the <code>hello()</code> function, but it seems redundant with the <code>@import</code> statement.</p>
<p>Moreover, the <code>readData()</code> IS correctly imported, why not the data? Should I somehow export the data as well?</p> | 3 |
Best way to sync VBOs between threads | <p>So I have a minecraft-like chunk system, meaning it's one block of render data. When the player moves around and enters another chunk, out-of-range chunks are being unloaded while new ones are being loaded, which makes it quite demanding since render data has to be calculated in another thread first before it can be shown.</p>
<p>Assuming the data is already loaded from the disk it looks like this</p>
<p>Main/Render Thread Render Data Generation Thread</p>
<pre><code> | Request Chunk |
| -------------------------------> |
| |
| | Generating render data (FloatBuffer)
| |
| .
| .
| .
| Get Ready Chunks |
| <------------------------------- |
| |
| Upload Data |
| |
| Render |
| |
</code></pre>
<p>"Request Chunk" and "Get Ready Chunks" are not synchronized so the render thread really works independently.</p>
<p>The problem with this is that uploading a lot of chunks at once causes framedrops, but calculating how much time I have left to upload can't be done reliably. If I only uploade one per frame I would miss out on alot of speed, although it works fine (That's how it's implemented at the moment).</p>
<p>Since I'm using only one GL context I can only create VBOs in the main thread at the moment.</p>
<p>Is there any way to solve this to be more efficently, like creating VBOs in the other thread and just passing them over to the main thread?</p> | 3 |
Inheritance: use inherited methods from parent pointer | <p>I'm working with some production code, some of which I cannot safely modify (without breaking things). My issue is that it I would like to use a specific method, one of the parameters of which is a pointer to a class. However the class as the parameter does not do what I want it to. </p>
<p>So I wrote a sub-class of that class and am attempting to call the above function, but it still uses the parent class' methods. </p>
<p>I have a MWE below:</p>
<pre><code>#include <iostream>
class Parent
{
public:
Parent() {};
void method() {std::cout<<"in Parent\n";}
};
class Child : public Parent
{
public:
Child() {};
void method() {std::cout<<"in Child\n";}
};
void secondMethod(Parent* Pptr)
{
Pptr->method();
}
int main()
{
Child c = Child();
Parent* parentPtr = &c;
c.method();
parentPtr->method();
secondMethod(parentPtr);
secondMethod(&c);
return 0;
}
</code></pre>
<p>In the above example running this the output is of course:</p>
<pre><code>in Child
in Parent
in Parent
in Parent
</code></pre>
<p>I believe the issue is slicing? Basically I'm casting to the pointer of the parent class, so it is considered as a Parent.</p>
<p>I have seen some ways around this by making methods virtual in the parent class but I don't have that option.</p>
<p>Is there some way to make secondMethod actual use the child's method? Specifically without changing the Parent class OR the secondMethod.</p> | 3 |
Different types JSON file using ObjectMapper | <p>I am using AlamofireObjectMapper to communicate with a backend server. The result of one of the requests is an array of items, which contain two values:</p>
<ul>
<li>A "typeIdentifier" indicating which type of data the second value ("arbitraryData") is of</li>
<li>A "arbitraryData":
<ul>
<li>If "typeIdentifier" CONTAINS "X", arbitraryData is of type ArbitraryDataTypeX</li>
<li>If "typeIdentifier" CONTAINS "Y", arbitraryData is of type ArbitraryDataTypeY</li>
</ul></li>
</ul>
<p>The two ArbitraryDataType classes do not share any common ancestor (except Mappable). It could be even a primitive type, an array, an optional, etc.</p>
<p>How can I make AlamofireObjectMapper parse the "arbitraryData" field using the appropriate type.</p>
<p>See the following JSON file:</p>
<pre><code>{
"arrayOfItems": [
{
"typeIdentifier": "X",
"arbitraryData":
{
"value": "BLA",
}
},
{
"typeIdentifier": "Y",
"arbitraryData":
{
"anotherValue": "BLUBB",
}
}
]
}
</code></pre>
<p>My corresponding Swing file looks like the following:</p>
<pre><code>class Item : Mapping {
var typeIdentifier = "X"
var arbitraryData: Mappable? = nil
init?(_ map: Map) {
self.init()
mapping(map)
}
func mapping(map: Map) {
typeIdentifier <- map["typeIdentifier"]
// THIS LINE CONTAINS MY QUESTION: HOW CAN I TELL OBJECTMAPPER, THAT,
// IF typeIdentifier CONTAINS "X", arbitraryData IS OF TYPE
// ArbitraryDataTypeX, AND IF "Y" arbitraryData IS OF TYPE
// ArbitraryDataTypeY?
arbitraryData <- map["arbitraryData"]
}
}
class ArbitraryDataTypeX : Mapping {
var value = "BLA"
init?(_ map: Map) {
self.init()
mapping(map)
}
func mapping(map: Map) {
value <- map["value"]
}
}
class ArbitraryDataTypeY : Mapping {
var anotherValue = "BLUBB"
init?(_ map: Map) {
self.init()
mapping(map)
}
func mapping(map: Map) {
anotherValue <- map["anotherValue"]
}
}
</code></pre>
<p>Background information: I am using AlamofireObjectMapper to communicate with a backend server. The result of one of the requests is an array of Item. The typeIdentifier-mechanism (infact it is a little bit more complex, but let's leave this out) is given by the backend and cannot be changed.</p> | 3 |
How to keep text horizontally during rotating transform of containing view | <p>Making custom UI control, something like rotation wheel, looks like this:

<p>As you can see labels positioned "on radiuses", but i need place all labels horizontal, and keep em same way when I will rotate container view</p> | 3 |
How to compare trimmed variable in SQL statement? | <p>I have a SQL statement which includes three database tables. I am comparing some IDs and DESCRIPTIONs and now I need to compare results FIRSTNAME, MIDDLENAME and SURNAME. </p>
<pre><code>SELECT UGOVARATELJ_OSIGURANJA AS ULJEZ FROM INS_RAZNO.TEST_DOWNJONES
WHERE UGOVARATELJ_OSIGURANJA IN
(SELECT FIRSTNAME||' '||MIDDLENAME||' '||SURNAME
AS IME_PREZIME
FROM (SELECT FIRSTNAME, MIDDLENAME, SURNAME
FROM INS_RAZNO.AML_CTF
WHERE ID IN (SELECT ID FROM INS_RAZNO.AML_CTF_DESCRIPTIONS
WHERE DESCRIPTION1='1' OR DESCRIPTION1='2')));
</code></pre>
<p>Variable <code>UGOVARATELJ_OSIGURANJA</code> is actually name of the client in form NAME MIDDNAME SURNAME, with spaces between each part of the name.
My idea was to remove those spaces with <code>REMOVE()</code> but when I compare after that with second table there is no correct result.</p>
<p>I tried to test my statement with this: THIS IS ONLY TEST STATEMENT</p>
<pre><code>SELECT REPLACE(UGOVARATELJ_OSIGURANJA, ' ','') AS ULJEZ FROM
INS_RAZNO.TEST_DOWNJONES WHERE UGOVARATELJ_OSIGURANJA LIKE '%IVAN F%'
</code></pre>
<p>Notice that I had to set space between name and middname <code>LIKE %IVAN F%</code> and correct way would be %IVANF%.</p>
<p>Any idea how to solve this? Thanks in advance</p>
<p>EDIT: I am doing this replacing (trimming) because some of the peops on my lists have not MIDDLENAME</p>
<p>EDIT:
This is working statement for names which has MIDDLENAME.
The statement is not working properly when someone has no MIDDLENAME because of one space too much.</p> | 3 |
Prevent link from looking like button | <p>I need my links to look like links and not buttons.
I've tried using removeClass to remove</p>
<pre><code>class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only ui-state-hover"
</code></pre>
<p>and removeAttr to remove </p>
<pre><code>role="button"
</code></pre>
<p>but both don't work. How should I prevent these classes from appending or just plainly make my links look like links?</p> | 3 |
swift 3.1 reading CSV or PLIST file from web | <p>I'd like to use readStringFromURL method to obtain a file from a plist and then use it on insertDataInArrayFromPlist in order to display it or put it on CoreData, substituting <code>let path = Bundle.main.path(forResource: plistFileName, ofType: plistFileExtension)</code>. </p>
<p>the ISSUE the try statement gives me this ERROR </p>
<pre><code>Argument labels '(contentsOfURL:, usedEncoding:)' do not match any available overloads
</code></pre>
<p>in my viewDidLoad:</p>
<pre><code>let obtainedfile = readStringFromURL(stringURL: kremoteSamplePlist)
print(obtainedfile ?? "nothing to print")
</code></pre>
<p>I retrive the file from web</p>
<pre><code> func readStringFromURL(stringURL:String)-> String!{
if let url = NSURL(string: stringURL) {
do {
return try String(contentsOfURL: url, usedEncoding: nil)
} catch {
print("Cannot load contents")
return nil
}
} else {
print("String was not a URL")
return nil
}
}
</code></pre>
<p>then I put the data in a struct</p>
<pre><code>func insertDataInArrayFromPlist(arrayOfEntities: inout [product]) {
let path = Bundle.main.path(forResource: plistFileName, ofType: plistFileExtension)
let localArray = NSArray(contentsOfFile: path!)!
for dict in localArray {
var futureEntity = product()
let bdict = dict as! [String: AnyObject]
futureEntity.name = bdict["Name"] as? String

for element in arrayOfEntities {
print("name is \(element.name!), the id is \(element.ProductId!)")

Linq results are displayed in different ordering | <p>I am currently fiddeling around with the AdventureWorks sample database and LinqPad, for scratching out some ideas.</p>
<p>This is the query in question:</p>
<pre><code>SalesOrderHeaders.GroupBy (soh => new {soh.CustomerID, soh.BillToAddressID})
.Where(soh => soh.Skip(1).Any())
.Dump();
</code></pre>
<p>The idea was to find duplicates based on some criteria and then display them except the first set of data. The result should be deleted from the table.</p>
<p>After executing the query I get result A)
<img src="https://i.stack.imgur.com/25jar.png" alt="First Result"></p>
<p>After executing the query again I get Result B)
<img src="https://i.stack.imgur.com/QFcKA.png" alt="enter image description here"></p>
<p>I do not care about the correct results of the query, but about the ordering of the resultset. Only those two possibilities exist and they alternate on every run of the query.
Surely I could just order by Key, but I am more interested in why does this even occur? Why is the order chaning/alternating?</p> | 3 |

Guidance needed - how to track nginx-docker-rails performance issue | <p>My Rails application is deployed on Amazon elastic beanstalk using Docker. Web requests flow into an nginx web server that forwards them to the thin rails server residing in docker. Somewhere along the way there's a bottleneck. Once every 50 requests (or so) I see nginx reports serving time which is x40 higher than the time the rails thin server reports.</p>
<p>here's an example:</p>
<p>NGINX (7490ms):</p>
<blockquote>
<p>146.185.56.206 - silo [18/Mar/2015:13:35:55 +0000] "GET /needs/117.json?iPhone HTTP/1.1" 200 2114 "-" "Mozilla/5.0 (Macintosh;
Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/40.0.2214.115 Safari/537.36" <strong>7.490</strong> 7.490 .</p>
</blockquote>
<p>THIN (rails server): 171ms</p>
<blockquote>
<p>2015-03-18 13:35:48.349 [INFO] method=GET path=/needs/117.json

</blockquote>
<p>Can anyone supply some guidance how to troubleshoot such a situation? How do I find the source of the response time difference? I guess it could be either nginx or docker or thin or linux.</p> | 3 |
Offsetting time_t in C++ | <p>I am dealing with timestamps generated by a system where the epoch is not the standard UNIX epoch of seconds since midnight of Jan 1, 1970 (it starts somewhere in 1965 instead). <a href="https://stackoverflow.com/questions/20521750/ticks-between-unix-epoch-and-gps-epoch">This</a> question is kind of related. So, I have a "fixup" function to deal with this offset:</p>
<pre><code>time_t fix_time(uint32_t raw_time)
{
const int32_t epoch_offset = 157680000; /* offset wrt UNIX epoch */
time_t fixedTime = static_cast<time_t>(raw_time - epoch_offset);
return fixedTime;
}
</code></pre>
<p>and continue using the standard library functions in rest of the code: </p>
<pre><code>uint32_t raw_time;
time_t timestamp = fix_timestamp(raw_time);
struct tm timeinfo;
gmtime_r(&timestamp, &timeinfo);
</code></pre>
<p>It seems to work as intended (held up to a mix of real and synthetic test data, so far). However, is there a better way to deal with this scenario? Are there any subtle ways in which this might break? Additional info if it matters: the timestamps are spread out over 1981 to the current day and the program runs on a Linux machine.</p> | 3 |

Android ViewFlipper auto animation / looping breaks at last child view | <p>I have made a ViewFlipper to simulate a slideshow component looping the slides continuously.
I configured it be:</p>
<pre><code>mViewFlipper.setAnimateFirstView(true);
mViewFlipper.setAutoStart(true);
</code></pre>
<p><strong>Everything works fine until the last slide (or child view).
At this moment the first slide appears abruptly without sliding !!!</strong></p>
<p>I checked the ViewFlipper and ViewAnimation source code and found the following:</p>
<pre><code> void showOnly(int childIndex, boolean animate) {
final int count = getChildCount();
for (int i = 0; i < count; i++) {
final View child = getChildAt(i);
if (i == childIndex) {
if (animate && mInAnimation != null) {
child.startAnimation(mInAnimation);
}
child.setVisibility(View.VISIBLE);
mFirstTime = false;
} else {
if (animate && mOutAnimation != null && child.getVisibility() == View.VISIBLE) {
child.startAnimation(mOutAnimation);
} else if (child.getAnimation() == mInAnimation)
child.clearAnimation();
child.setVisibility(View.GONE);
}
}
}
</code></pre>
<p>As you can see this method always starts with the lowest index to animate-in.</p>
<p>For example if I have 5 slides:</p>
<p>when the slide #4 is visible and should be replaced by slide #0, the slide #0 is animated-in before slide #4 is animated-out, which makes the animation sudden and not smooth at all.</p>
<p>Does anybody have any workaround to this problem ?</p>
<p>Thanks</p> | 3 |
Catching uncaught exceptions | <p>In my workplace we are mantaining a lot of ecommerce websites, some coded better than others. On some of those, sometimes uncaught exceptions are thrown, and showed by the alertbox from the flash player debug (If you have it installed).</p>
<p>To rise the average user experience I'd like to report all those exceptions throught a in house tool we already have.</p>
<p>Is there a way to catch those exceptions?
Maybe the flash player debug exposes them to javascript, or in some other way.</p> | 3 |
Cocos2d Changing Scenes: BAD_ACCESS Exception | <p>I have sincerely tried to understand the error from any remotely related question I have seen here. However, the issue that I am having is that when I try to transition from my level1 scene to levelselector scene, the game crashes with the bad access exception. The menus and transitions worked flawlessly while I was using them among main menu, credits, levelselector and all.
Now I do know that the error is on the main thread.
The selector shows that it is at </p>
<pre><code> int retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate");
</code></pre>
<p>now on my level1 scene, I do have three thread using [self schedule] and I have put in the corresponding [self unschedule];</p>
<p>I also have a NSMutableArray which I tried releasing and pointing to nil but I get another error. I put it in the dealloc method of the scene. I did the same with the [self unschedule] as well. Is there a better place to put it?</p>
<p>here is how it looks like, had forgotten to retain the stuff. release is working fine now but still crashes right after the transition. the scene loads as in I can see it, but then it crashes right away. </p>

Python: Modifying pprint behavior for a class or object? | <p><strong>Note:</strong> This question is about the mechanics of pprint and not asking about namedtuples. Namedtuples are used as a tangible example, but the question is not "how do I make namedtuple more beautiful for pprinting?"</p>
<hr />
<p>What method does <code>pprint</code> call to display an object's data?
How can I override this?</p>
<p>In this example, I would like to pretty print the named tuple <code>d</code> so that it prints one data element per line, similar to how the dict <code>a</code> is being printed.</p>
<pre><code>>>> import pprint
>>> import collections
>>> a={'a': 'a'*40, 'b': 'b'*40}
>>> d=collections.namedtuple('D', 'a b')('a'*40, 'b'*40)
>>> # How do I make d print similarly to a?
>>> pprint.pprint(a)
{'a': 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa',
'b': 'bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb'}
>>> pprint.pprint(d)
D(a='aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa', b='bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb')

How to run DatabaseUtil.precomputedKNNQuery method of LOF class on two different threads | <p>I want to reduce runtime of DatabaseUtil.precomputedKNNQuery method by running this method on two different threads and KNNQuery is an interface.</p>
<pre><code> KNNQuery<O> knnq = DatabaseUtil.precomputedKNNQuery(database, relation, getDistanceFunction(), k);
</code></pre>
<p>I divided this method of LOF class in two parts like this</p>
<pre><code> Callable<KNNQuery> task1(Database database, Relation<O> relation){
DBIDs idss = relation.getDBIDs();
ArrayDBIDs aids = (ArrayDBIDs) idss;
aids = aids.slice(0, (aids.size() / 2));
aids.size();
ProxyView<O> pv = new ProxyView<>(aids, relation);
return () -> {
return DatabaseUtil.precomputedKNNQuery(database, pv,
getDistanceFunction(), k);
};
}
Callable<KNNQuery> task2(Database database, Relation<O> relation) {
DBIDs idss = relation.getDBIDs();
ArrayDBIDs aids = (ArrayDBIDs) idss;
aids = aids.slice(((aids.size() / 2) - 1), aids.size());
aids.size();
ProxyView<O> pv2 = new ProxyView<>(aids, relation);
return () -> {
return DatabaseUtil.precomputedKNNQuery(database, pv2, getDistanceFunction(), k);
};
}
</code></pre>

<pre><code> public OutlierResult run(Database database, Relation<O> relation) {
StepProgress stepprog = LOG.isVerbose() ? new StepProgress("LOF", 3) : null;
DBIDs ids = relation.getDBIDs();

// Compute LRDs
// compute LOF_SCORE of each db object
// Build result representation

<p>But i am getting exception which is saying something like this because forEach is providing only output of first future in knnq variable but not the combined output of both future's. Please help me how can i get rid of this exception with example thanks?</p>

Bundle synchronization in B2C project | <p>I am working on a B2C project.</p>
<p>We are using customized bundle implementation in our project.</p>
<p>However we were struggling with making bundle synchronization work.</p>
<p>With some effort, we managed to find the ImpEx to synchronize the Bundle:</p>
<pre><code> UPDATE CatalogVersionSyncJob;code[unique=true];roottypes(code)[mode=append];
;$syncJobCode;BundleTemplate,BundleTemplateStatus;
</code></pre>
<p>However, I am worried whether this will also synchronize the ChangeProductPriceBundleRule available out of the box.</p>
<p>Also how do I synchronize this from backoffice?Is running this cronjob from the Backoffice the only solution?How do Backoffice users see a Synchronize button?Is creating a separate node necessary?</p> | 3 |
Laravel eloquent order by subquery | <p>I have a problem with ordering by columns in subquery (lastname, firstname).</p>
<p>I already tried this code as suggested by other posts:</p>
<pre><code>->with(['customer' => function ($query) {
$query->orderBy("lastname", "asc")
->orderBy("firstname", "asc");
}])
</code></pre>
<p>Here my full code, but it doesn't work.</p>
<pre><code>return Membership::forCompany($companyId)
->whereIn('state', ['ATTIVA', 'IN ATTESA DI ESITO', 'DA INVIARE'])
->where(function ($query) {
$query->where('end_date', '>=', Carbon::now()->toDateString())
->orWhereNull('end_date');
})
->with('federation')
->with(['customer' => function ($query) {
$query->orderBy("lastname", "asc")
->orderBy("firstname", "asc");
}]);
</code></pre>
<p>Here the relationships:</p>
<p>In customer model I have:</p>
<pre><code>public function memberships() {
return $this->hasMany('App\Models\Membership');
}
</code></pre>
<p>In Membership model I have:</p>
<pre><code>public function customer() {
return $this->belongsTo("App\Models\Customer");
}

Determine whether in two rows one is a header or not | <p>I am trying to do a task that is quite simple to do by a human: detect whether the first of two rows is a header row. Here's an example of sample inputs:</p>
<p>Example1: yes</p>
<pre><code>name,age
bob,12
</code></pre>
<p>Example2: yes</p>
<pre><code>first,last
bob,jones
</code></pre>
<p>Example3: no</p>
<pre><code>1,2
8,hi
</code></pre>
<p>Example4: no</p>
<pre><code>bob,jones
tom,smith
</code></pre>
<p>I'm a bit lost of where to begin to make an educated guess here. It doesn't have to be perfect (80% would be good), but what might be a good short-hand algorithm to determine the above? Some things I was thinking of:</p>
<pre><code># header is usually always strings (wrong in case 4)
for val in header:
is val.replace(',','').replace('.','').replace('-','').isdigit():
header = False
else:
header = True
</code></pre> | 3 |
How to get Title Text color of Toolbar? | <p>In my current project, I'm trying to translate color of Toolbar and it's Title Text from current color to a new color. But I can't find a function in the Toolbar something like <code>toolbar.getTitleTextColor()</code> but there is a function to set color. </p>
<p>Here's my layout </p>
<pre><code><com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:alpha="0.7"
android:id="@+id/bottombarAppbar"
android:layout_height="wrap_content">
<com.google.android.material.appbar.MaterialToolbar
android:id="@+id/bottombarToolbar"
app:navigationIcon="@drawable/ic_hide"
app:title="Categories"
app:titleTextColor="#fafafa"
android:layout_width="match_parent"
android:layout_height="?actionBarSize" />
</com.google.android.material.appbar.AppBarLayout>
</code></pre>
<p>The statement below causes error because it's not defined.</p>
<pre><code>bottombarToolbar.getTitleTextColor()
</code></pre>
<p>Did I miss anything?</p> | 3 |
JPA Hibernate Configuration Errors | <p>I want to enable JPA for an EJB module, in an IntelliJ J2E project. I don't have an existing database schema to import; I want to generate the schema and tables from my EJB POJO class. I then want to generate ORM mappings.</p>
<p>I've enabled JavaEE Persistence framework support in IntelliJ, with Hibernate as the provider. I've updated persistence.xml and assigned MySQL@localhost as the data source, to the JPA persistence unit. I've also added the JPA descriptor to the ear artifact.</p>
<p>When I try to add the JPA annotations to my POJO, e.g. @Table, @Column etc, I get an error "Cannot resolve table 'TABLE_NAME'"...same applies for columns. The context action I get is 'Assign Data Sources', but the data source is showing as assigned to the persistence unit.</p>
<p>I've run the code and now just get a huge stack trace.</p>
<p>The tutorials i've found are either for importing an existing schema (which I don't have), or use other IDEs. My persistence.xml and one of my pojos are included below</p>
<p>Thanks in advance..</p>

SLURM squeue format argument fails from subprocess.Popen | <p>I'm trying to call the <a href="https://slurm.schedmd.com/squeue.html" rel="nofollow noreferrer">SLURM squeue</a> from a python script. The command,</p>
<p><code>/usr/bin/squeue --Format=username,jobid,name,timeleft</code></p>
<p>Works fine from the command line, but fails from <a href="https://docs.python.org/3/library/subprocess.html#subprocess.Popen" rel="nofollow noreferrer"><code>subprocess.Popen</code></a> with:</p>
<pre><code> p = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

<p><code>/usr/bin/squeue</code> works fine from both the command line or <code>Popen</code>.</p>
<p>Could it be failing because it requires some information about the user/group that's executing the <code>squeue</code> command and that is (somehow) lost when running via python? What else could be causing this?</p> | 3 |
jQuery Scroll Event Not Working With Section | <p>I'm trying to make a simple scrollspy with jQuery Scroll event but it fails. Here is my JavaScript part:</p>
<pre><code><script>
$(document).ready(function(){
$("#credit_card").scroll(function(){
console.log('OK');
});
});
</script>
</code></pre>
<p>And HTML part:</p>
<pre><code><section class="method first-of-group" id="credit_card">
...
</section>
</code></pre>
<p>As you might have guessed, <code>console.log</code> is just for testing. This section is under a div and this div has "content" id. If I change my JavaScript code for "content" id, it is working. It's really weird. </p>
<p>If you want to see it live, please visit <a href="https://projects.denizb16.com/document/" rel="nofollow noreferrer">here</a>.</p>

Most efficient way to detect current element in scroll navigation | <p>Im not sure how to find what I need (name it) so I count on you to explain it for me.</p>
<p>I need to create javascript content navigation based on "post" or "comment" system. First of all I want to emphasize that content is not plain text but It contain HTML, images and other objects that can resize during usage.</p>
<p><strong>How does it look?</strong>
One container for content divided to sections and one for dedicated navigation scroll - this scroll is snapped relatively to sections.</p>
<p><a href="https://i.stack.imgur.com/YKLVE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YKLVE.png" alt="enter image description here"></a></p>
<p>Whole system is very simillar to discourse posts navigation -
<a href="https://try.discourse.org/" rel="nofollow noreferrer">check discourse here</a></p>
<ul>
<li>Most important thing for me is to keep synchronization for scroll and content.</li>
<li>If you click 3th post in scroll, content should scroll to this post - this is easy.</li>
<li>If you scroll by mouse content is scrolled + dedicated navigation is automatically synchronised - this is my problem I think.</li>
</ul>
<p><strong>What is the best* way to check which one section is my current section.
Should I find visible element? bounding rectangle? calculate it based on heights of all sections?</strong></p>
<p>PS If you have any library working in similar way you can post it as addition - it can be helpful for me.</p>
<p><strong>//edit</strong></p>
<p><strong>*best</strong> - simple, not too slow if I get more elements (100-1000), takes into consideration dynamic content (resize) and also supported by all modern browsers. Probably there is more than 3 methods but if you post more alternatives, Me or someone else can pick suitable solution.</p> | 3 |
React Component div id will not hide what used in map loop | <p>I have this code in an index.html file which loads with the application:</p>
<pre><code>$(window).on('load', () => {
$('#one').hide();
$('#oneb').hide();
});
</code></pre>
<p>And this affects the component:</p>
<pre><code>import React from 'react';
const Test = (props) => <div id="MyDiv">
<div>
<div id="one">
THIS IS ONE
</div>
{
props.list.map((data, i) => {
return <div id="oneb" key={i}>
THIS IS ONEB
</div>
})
}
</div>
</div>
</code></pre>
<p>What is happening here is that div with id="one" will hide BUT id="oneb" will still show up.</p>
<p>Why is this happening? How can I fix this?</p> | 3 |

Merge columns from Multiple Sheets into Summary Sheet without blanks | <p>I have many sheets of which some are <strong>A, B, C and D.</strong>
Each of them have different data sets, however columns <strong>E,F,G</strong> have the same type of data.</p>
<p>I would like to merge the data from the columns E,F,G of the sheets A, B, C and D Paste in <strong>Columns A,B,C</strong> of <strong>Sheet Summary</strong>. </p>
<p>The problem I am facing is that the range E2:G(last row with data) has empty rows in the beginning and also in the Middle. Example: E2:G10 is blank and data might be present from E11:G30. This is making my copy paste erroneous.</p>
<p>The Following is the Code I have written. But, for some reason the data in the Sheet D is altered. Also, as I did not know how to exempt empty rows while copying, I used a separate code block to delete the empty rows at the end of copy paste activity in the Sheet Summary.</p>
<pre><code>Sub CopyRange()
Dim bottomD As Integer
Dim ws As Worksheet
For Each ws In Sheets(Array("A", "B", "C", "D"))
ws.Activate
bottomD = Range("E" & rows.Count).End(xlUp).Row
Range("E2:G" & bottomD).Copy Sheets("Summary").Cells(rows.Count,"E").End(xlUp).Offset(1, 0)
Next ws
Dim r As Range
Dim rows2 As Long
Dim i As Long
Set r = ActiveSheet.Range("A:A")
rows2 = r.rows.Count
For i = rows2 To 1 Step (-1)
If WorksheetFunction.CountA(r.rows(i)) = 0 Then r.rows(i).Delete
Next
End Sub

Firebase data ordering | <p>I feel as if I'm missing something big when I use firebase in my android app. I have been using</p>

Sticky navbar makes content jump on way back up | <p>I Have a simple site set up with a header, navbar and content. When the page reaches the navbar, the position becomes fixed so the navbar sits at the top of the page - at this point, the navbar height also gets a bit smaller (as I like this effect) - I have done this by adding separate classes, fixed and thinner to the navbar.</p>
<p>Most people are aware of the issue that occurs when you add "position:fixed" to an inline element in that it makes the content suddenly "jump" upwards. To counteract this i have added a div called "stop_the_jump" which is hidden until the navbar becomes fixed, at which point it is displayed in it's place. All of this runs smoothly on the way down, but as you scroll back up you get a jump due to the fact that the navbar is now thinner.</p>
<p>I'm pulling my hair out over this one, how can I eliminate this jump that occurs on the way back up.</p>
<p>Here is a JSFiddle clearly showing my issue:
<a href="http://jsfiddle.net/gnac14qa/" rel="nofollow">http://jsfiddle.net/gnac14qa/</a></p>
<p>My jQuery code is as follows:</p>
<pre><code>$(window).scroll(function() {
var Scroll = $(window).scrollTop();
var ScrollFXfullHeight = $('.header-wrapper').height();
if (Scroll == ScrollFXfullHeight) {
$("#navigation").addClass("fixed");
$(".stop_the_jump").css('display','block');
} else if (Scroll > ScrollFXfullHeight) {
if(!$("#navigation").hasClass('fixed')) {
$(".stop_the_jump").css('display','block');
$("#navigation").addClass("fixed");
}
$("#navigation").addClass("thinner");
} else {
$("#navigation").removeClass("thinner fixed");
$(".stop_the_jump").removeClass("thinner");
$(".stop_the_jump").css('display','none');
}
