Jest transformIgnorePatterns not working : <p>I have spent a long time looking at other questions about this and looking at other projects on Github but none of the answers seem to work for me.</p>
<p>I am loading a third party library in my project, and when running Jest tests I get the error</p>
<pre><code>export default portalCommunication;
^^^^^^
SyntaxError: Unexpected token export
> 1 | import portalCommunication from 'mathletics-portal-communication-service';
</code></pre>
<p>I have tried updating my Jest config in many ways to get it to transpile this library but I always get the same error.</p>
<p>This is my current jest.config.js file:</p>
<pre><code>module.exports = {
moduleNameMapper: {
'\\.(css|scss)$': 'identity-obj-proxy',
'\\.svg$': '<rootDir>/test/mocks/svg-mock.js'
},
setupFiles: ['./test/test-setup.js'],

'<rootDir>/node_modules/(?!mathletics-portal-communication-service)'

};
</code></pre>
<p>I have also tried adding the transform property to run babel-jest against this mathletics-portal-communication-service directory.</p>

Remove specific element from array of specifc object : <p>I need to modify a nested array. In this example I would like to remove <code>content 2</code> from the target array of the object with the id <code>ZFrNsQKSY6ywSzYps</code></p>
<pre><code>var array = [
{ _id: "QKSY6ywSzYpsZFrNs", target: ["content 1"]}
{ _id: "ZFrNsQKSY6ywSzYps", target: ["content 1", "content 2"]}
{ _id: "SzYpsZFrNQKSY6yws", target: ["content 1"]}
]
</code></pre>
<p>I tried to use <code>find()</code> but with that I do not update the array. So this seems not to be the correct approach.</p>

Increment double pointer by 1 : I'm learning c pointers. There i have incremented double pointer by 1. then i could get as follows
current ptr_double =0x0128
then i incremented it by 1
so ptr_double plus 8 bytes , That is 0x0128+8 which gives `0x0130` , But i'm unable to understand how `0x0130` comes. Please be kind enough to explain me. I know its stupid question. But i couldn't understand so far.

Angular 2 Focus on first invalid input after Click/Event : <p>I have an odd requirement and was hoping for some help.</p>
<p>I need to focus on the first found invalid input of a form after clicking a button (not submit). The form is rather large, and so the screen needs to scroll to the first invalid input.</p>
<p>This AngularJS answer would be what I would need, but didn't know if a directive like this would be the way to go in Angular 2:</p>

Javascript: Sort Object by value : <p>I have the following object: </p>
<pre><code>{1234: "3.05", 1235: "2.03", 1236: "3.05"}

<p>I would like to sort them by <strong>value</strong> to get something like this:</p>
<pre><code>{1235: "2.03", 1234: "3.05", 1236: "3.05"}
</code></pre>
<p>I tried:</p>
<pre><code>const sortedList = _.orderBy(myList, (value, key) => {
return value;
}, ['asc']);
</code></pre>
<p>The values get sorted but it is only a list of values:</p>
<pre><code>{0: "2.03", 1: "3.05", 2: "3.05"}
</code></pre>
<p>How can I retain the keys?</p>

How to reset the use/password of jenkins on windows? : <p>Maybe a fool question, I installed jenkins on windows by default, have set no user/password, it worked at first, no need to login. But when launch the 8080 webpage now, it hangs the login page, I've tried some normal user/password combinations, none could pass. Also searched the resolution on website, only find some about linux, no about windows, so need help.

How can I receive an uploaded file using a Golang net/http server? : <p>I'm playing around with <a href="https://github.com/gorilla/mux" rel="noreferrer">Mux</a> and <code>net/http</code>. Lately, I'm trying to get a simple server with one endpoint to accept a file upload.</p>
<p>Here's the code I've got so far:</p>
<p><strong>server.go</strong></p>
<pre><code>package main
import (
"fmt"
"github.com/gorilla/mux"
"log"
"net/http"
)
func main() {
router := mux.NewRouter()
router.
Path("/upload").
Methods("POST").
HandlerFunc(UploadCsv)
fmt.Println("Starting")
log.Fatal(http.ListenAndServe(":8080", router))
}
</code></pre>
<p><strong>endpoint.go</strong></p>
<pre><code>package main
import (
"fmt"
"net/http"
)
func UploadFile(w http.ResponseWriter, r *http.Request) {
err := r.ParseMultipartForm(5 * 1024 * 1024)
if err != nil {
panic(err)
}
fmt.Println(r.FormValue("fileupload"))
}
</code></pre>
<p>I think I've narrowed the issue down to actually retrieving the body from the request inside <code>UploadFile</code>. When I run this cURL command:</p>
<pre><code>curl http://localhost:8080/upload -F "fileupload=@test.txt" -vvv
</code></pre>
<p>I get an empty response (as expected; I'm not printing to the <code>ResponseWriter</code>), but I just get a new (empty) line printed at the prompt where I'm running the server, instead of the request body.</p>
<p>I'm sending the file as multipart (AFAIK, implied by using <code>-F</code> rather than <code>-d</code> in cURL), and cURL's verbose output is showing 502 bytes sent:</p>
<pre><code>$ curl http://localhost:8080/upload -F "fileupload=@test.txt" -vvv
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)

<p>What's the proper way to receive files uploaded as multipart form data using a <code>net/http</code> server in Go?</p>

Configure Apache with multiple ProxyPass : <p>i am trying to configure my apache server as proxy to serve two internal services , one listening on 8080 and should receive traffic on specific URL and the other listening on 8077 and should receive all other http traffic</p>
<p>I deployed and configured apache on the same server where these two services running and it is listening to 443 along with all SSL configuration and it is working fine</p>
<p>also I enabled the proxy_module, proxy_http_module and proxy_http2_module</p>
<p>What I want to achieve </p>
<p>if the requested URL is /webhook1 --> pass it to EP1 <a href="http://localhost:8080" rel="noreferrer">http://localhost:8080</a> and
any other requested URL should be passed to EP2 <a href="http://localhost:8077" rel="noreferrer">http://localhost:8077</a></p>
<p>My Current Configuration towards the first service </p>
<pre><code>ProxyPass /webhook1 http://localhost:8080
ProxyPassReverse /webhook1 http://localhost:8080
</code></pre>
<p>Now I want to define another proxy pass to be something like</p>
<pre><code>ProxyPass / http://localhost:8077
ProxyPassReverse / http://localhost:8077
</code></pre>
<p>putting both configuration together is not working , appreciate your help in how to configure apache to achieve my requirement</p>

Make SLE 5542 Smart Cards Read Only After Binary Write Using APDU : <p>Excited to ask my first question over here... so here goes.. </p>

<ol>
<li><p>Read write of values in Blocks of the sector </p></li>
<li><p>changing the access bits and authentication key A and B for the sector trails so as manage the access control of the sector of the block in which i have written so that i can make my values read only.</p></li>
</ol>
<p>As for the Chip Encode i have managed to .</p>
<p>Performing read write in the Contact Chip using READ BINARY AND WRITE BINARY APDU commands.</p>
<p>But Now i am stuck in the process of making the values written in the chip to be readonly , </p>
<p>I found a <a href="http://www.acs.com.hk/download-manual/6009/TDS_SLE5542.pdf" rel="nofollow">document</a> over the internet in which under the Circuit Description it is telling about the need of PSC And Protection Memory for the read protection of the Data Memory</p>
<p>But can not find the exact APDU Commands and the right way of the read write protection of the data memory.</p>
<p>P.S Let me know if you need any further clarifications</p>

In echarts3, how to force axis labels to display : <p>Echarts seems to have a nice feature that automatically chooses which labels to display depending on the space provided. However, this algorithm seems to be bit too aggressive at times and does not take into account text rotate. I've gone through the chart options and there doesn't appear to be a way to disable this feature. I'm hoping it's just something I've overlooked. Help appreciated.</p>

How do we overcome the compile time and runtime gap when programming in a Dependently Typed Language? : <p>I'm told that in dependent type system, "types" and "values" is mixed, and we can treat both of them as "terms" instead.</p>
<p>But there is something I can't understand: in a strongly typed programming language without Dependent Type (like Haskell), Types is decided (infered or checked) at <strong>compile time</strong>, but values is decided (computed or inputed) at <strong>runtime</strong>.</p>
<p>I think there must be a gap between these two stages. Just think that if a value is interactively read from STDIN, how can we reference this value in a type which must be decided AOT?</p>
<p>e.g. There is a natural number <code>n</code> and a list of natural number <code>xs</code> (which contains n elements) which I need to read from STDIN, how can I put them into a data structure <code>Vect n Nat</code>?</p>

Angular 2 event when any [routerLink] is clicked : <p>I have a simple Loader Service that hides and shows certain loaders. I'm working on something that will be used a lot with slow connections and I need to show/hide a loader between route changes. </p>
<p>I can hide the loader when the new route is loaded with the following.</p>
<pre><code>this._Router.subscribe(() => {
this._LoaderService.hide();
})
</code></pre>
<p>I'm trying to find a way that I can call my <code>this._LoaderService.show()</code> function immediately when any [routerLink] is clicked (at the start of the route change, not the end).</p>
<p>I've had a look around and I tried <a href="https://angular.io/docs/ts/latest/api/router/Router-class.html" rel="noreferrer">https://angular.io/docs/ts/latest/api/router/Router-class.html</a> but I can't seem to figure it out.</p>

Angular2: How do you mark FormGroup control dirty via `patchValue()` : <p>I am updating a Reactive <code>FormGroup</code> control value from my component via <a href="https://angular.io/docs/ts/latest/api/forms/index/FormGroup-class.html#!#patchValue" rel="noreferrer">patchValue</a>.</p>
<p>Ex:</p>
<pre><code>this.myForm.patchValue({incidentDate:'2016-09-12');
</code></pre>
<p>This works great and triggers a <code>valueChanges</code> event, however this control's <code>dirty</code> property is still <code>false</code>.</p>
<p>I need the <code>incidentDate</code> control to be <code>dirty</code> so my validation logic knows to run against this control.</p>
<p>How do I update the value of a control from my component AND indicate that it is dirty?</p>
<p>Here is my validation logic:</p>
<pre><code>onValueChanged(data?: any) {
if (!this.myForm) {
return;
}
const form = this.myForm;
for (const field in this.formErrors) {
// clear previous error message (if any)
this.formErrors[field] = '';
const control = form.get(field);
if (control && control.dirty && !control.valid) {
const messages: any = this.validationMessages[field];
for (const key in control.errors) {
this.formErrors[field] += messages[key] + ' ';
}
}
}

How to mock a function, that is imported within an imported method from different module : <p>I got the following function to test:</p>
<p><strong>my_package.db_engine.db_functions.py:</strong> </p>
<pre><code>from ..utils import execute_cmd
from my_package.db_engine.db_functions import dbinfo
def dbinfo(db_name):
params = (cmd_cfg.DB, add_pj_suffix(db_name))
cmd = get_db_cmd_string(cmd_cfg.DBINFO, params=params)
cmd_result = execute_cmd(cmd)
result_dict = map_cmd_output_to_dict(cmd_result)
return result_dict
</code></pre>
<p>This function takes the name of a database, then builds a command string from it and executes this command as <code>subprocess</code> with the <code>execute_cmd</code> method.
I want to test this function without actually executing the <code>subprocess</code>. I only want to check if the command is built correctly and correctly passed to <code>execute_cmd</code>. Therefore I need to mock the <code>execute_cmd</code> method which is imported from module <code>utils</code>.</p>
<p>My folder structure is the following:</p>
<pre><code>my_project
|_src
| |_my_package
| | |_db_engine
| | | |_db_functions.py
| | | |_ __init__.py
| | |_utils.py
| | |_ __init__.py
| | |_ ....
| |_ __init__.py
|_tests
|_test_db_engine.py
</code></pre>
<p>So for my test I tried the following in <code>test_db_engine.py</code>:</p>
<pre><code>import unittest
from mock import patch
from my_pacakge.db_engine.db_functions import dbinfo
def execute_db_info_cmd_mock():
return {
'Last Checkpoint': '1.7',
'Last Checkpoint Date': 'May 20, 2015 10:07:41 AM'
}
class DBEngineTestSuite(unittest.TestCase):
""" Tests für DB Engine"""
@patch('my_package.utils.execute_cmd')
def test_dbinfo(self, test_patch):
test_patch.return_value = execute_db_info_cmd_mock()
db_info = dbinfo('MyDBNameHere')
self.assertEqual(sandbox_info['Last Checkpoint'], '1.7')
</code></pre>
<p>The execution of the actual command yields <code>1.6</code> for <code>Last Checkpoint</code>. So to verify if the mock return value is used, I set it to <code>1.7</code>.
But the mock for the function is not used, as the execution of the test case still yields <code>1.6</code> because it is executing the actual function that should have been patched with the mock.</p>
<p>Any idea what I got wrong here?</p>

build.gradle: compile group vs compile, buildscript, classpath : <p>What is the difference between "compile group" and "compile"? Just another way to define a dependency?</p>
<p>Ex:</p>
<pre><code>compile group: 'org.slf4j', name: 'slf4j-jcl', version: '1.7.21'
</code></pre>
<p>And i think this also will work:</p>
<pre><code>compile("org.slf4j:slf4j-jcl:1.7.21")
</code></pre>
<p>Why do i have the declare <code>mavenCentral()</code> again and another dependencies block inside the buildscript block?</p>
<pre><code>buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.0.RELEASE")
}
}
</code></pre>
<p>From my point of view, when you compile something it will be in your classPath?</p>

ERROR_INVALID_PARAMETER in VC++ code : I have written a routine that uses the native C++ "HTTPDECLAREPUSH" method to utilize server push. I am passing the parameters as below, still getting error # 87 (ERROR_INVALID_PARAMETER) at `HttpDeclarePush(p_req_queue_handle, request_id, verb, http_path, query, headers);`

Best practices for storing a Token in iOS app : <p>I'm creating an iOS that interacts with an API using Alamofire, and requires a Token for most requests. I've built the app using the MVC pattern, and it works great, but I've encountered a problem as I've tried to integrate the API. How should I share/store the token so that it can be accessed from the view controllers/models? I've read up quite a bit and have found negative opinions on using singletons or <code>UserDefaults</code>, but I've yet to encounter a straightforward answer. I understand this is a pretty broad question that might not have a simple answer, but I am pretty new to this and was wondering if anyone can help point me in the right direction. Thanks!</p>

Why java packages do not work as a hierarchy? : <p>why java does not allow access to package restricted types that are in parents package?</p>
<p>With something like :</p>
<pre><code>Package a
|--Class A
|--Package b
|--Class B
</code></pre>
<p>It is not possible to access class <code>A</code> from class <code>B</code> if class <code>A</code> has package visibility. I thought it make sense but apparently not.</p>
<p>What is the reason for that?</p>

Find dead code in Golang monorepo : <p>My team has all our Golang code in a monorepo.</p>
<ul>
<li>Various package subdirectories with library code.</li>
<li>Binaries/services/tools under <code>cmd</code></li>
</ul>
<p>We've had it for a while and are doing some cleanup. Are there any tools or techniques that can find functions not used by the binaries under <code>cmd</code>?</p>
<p>I know <code>go vet</code> can find private functions that are unused in a package. However I suspect we also have exported library functions that aren't used either.</p>

VB Code to Drag Formula to Visible Rows Only : I've tried searching for this but have only ended up with a non-functioning Frankenstein sub routine. I need to:
-Filter Column B to Grey Cells.
-In column AB on all visible rows, set formula equal to the values in Column B.
If a row is filtered out, I need it to remain blank.
Bonus question (because I'm a pain in the neck): I need to do some kind of loop to replicate this process in columns AC:BA as well. For example, filter Column C to grey cells, and make all visible cells in AC equal to the corresponding row in Column C.
EDIT: I was also thinking to just do a Control + Find, replace any cell where the background color is no fill, and replace with a blank or 0. I can't get that to work either, however.
Code that I have (currently I'm stuck at having selected the first visible cell in Column AB):
Dim Last_Cell As Range
Set Last_Cell = Range("A3").SpecialCells(xlLastCell)
' [Good ]Filter Column B by Color
Range("$A$3", Last_Cell).AutoFilter Field:=2, Criteria1:=RGB(165,165,_
165), Operator:=xlFilterCellColor
' [Pending ] Set all visible AB cells = same row in B
Range("AB3").Offset(1, 0).Activate
Do Until Selection.EntireRow.Hidden = False
If Selection.EntireRow.Hidden = True Then
ActiveCell.Offset(1, 0).Activate
End If
Loop

When i try to call `bookService.createBook("Java book")` it throw a `java.lang.NullPointerException`, in `generator.generateNumber()` i think it not call the right `@Qualifier`, a tried to solve this problem, using this link, http://stackoverflow.com/questions/21363931/java-ee-7-cdi-injection-doesnt-work-sending-nullpointerexception i add all the dependencies but the problem still the same?
Did i miss something?
**Note** i know about http://stackoverflow.com/questions/218384/what-is-a-nullpointerexception-and-how-do-i-fix-it
Thank you.

Javascript: Expected Identifier : <p>I am creating an HTML document and using javascript to create an image element.
Here is my code (create is already defined):</p>
<pre><code>create=document.createElement("img");
create.src = 'data/1.png';
create.alt = 'image1';
create.style.magin = '1px';
eval("create.id = 'image" + count + "'");
create.class = 'block'; // line that breaks the code
document.body.appendChild(create);
</code></pre>
<p>I don't know what's going wrong here, but it's probably something obvious. Does anyone have any ideas?</p>

How to add custom font sizes to QuillJS editor : <p>How do you add custom font sizes to the toolbar with QuillJS? I've tried two approaches:</p>
<pre><code>// Initiate the editor
let toolbarOptions = [
['bold', 'italic', 'underline', 'strike'],
[{ 'align': [] }],
[{ 'size': ['10px', '20px', '80px'] }],
[{ 'color': ['#FFF'] }]
];
this.editor = new Quill('#executive-control-editor', {
modules: {
toolbar: toolbarOptions
},
theme: 'snow'
});
</code></pre>
<p>and</p>
<pre><code><div id="toolbar">
<span class="ql-formats">
<button class="ql-bold"></button>
<button class="ql-italic"></button>
<button class="ql-underline"></button>
<button class="ql-strike"></button>
</span>
<span class="ql-formats">
<select class="ql-align"></select>
</span>
<span class="ql-format-group">
<select title="Size" class="ql-size">
<option value="10px">Small</option>
<option value="13px">Normal</option>
<option value="18px">Large</option>
<option value="32px">Huge</option>
</select>
</span>
<span class="ql-formats">
<button class="ql-image"></button>
</span>
</div>
</code></pre>
<p>However neither of them work. Is there something I'm missing here? I've tried removing the <strong>"px"</strong> from the value as well; still nothing.</p>
