Let's say you use the user name "<PERSON>" to connect to the network using PPTP VPN. <PERSON> doesn't have the rights to acces the folder "B" on the network. Does that mean I too can't access the folder if I use <PERSON>'s user name to connect (in the Windows own VPN connection dialog)?
Or is the user name completely meaningless and just establishes a tunnel over VPN and has nothing to do with the ACLs in any way?

decide whether or not you need to conjoin/compress the files at all
don't implement something like this yourself
use .NET's ZipFile class
When you re-open the file as a stream, you could use the stream's Seek method to go to the desired position (which you'd have to remember somewhere), and then read out the desired number of bytes (which you'd also have to either remember, or mark the end of the files with a marker bit). Modifying the files would also be immense fun.
Don't do it! You'd be writing a bad tar equivalent, and plenty of other people have already done it, and better:
sharpcompress
sharpziplib
.NET's own ZipFile
Also note that .NET's binary serialisation is not guaranteed to be readable in later .NET versions. It's meant for transient things and not data archival. This may be important to you, and is another thing to consider.
I don't know how what you're doing with the files; you might not want/need to do that - you might just be better off storing the things on disk as individual files. If compression/storage as a single file is in fact your thing, then I would recommend starting with .NET's ZipFile class, as you'd have no outside dependencies.

I removed the <a> tag from around the W3 logo and added an onclick JavaScript function validatePage(). So here is basically a template for an XHTML Strict page that still allows you to include the validation icon.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<title>Title of document</title>
<script type="text/javascript">
function validatePage() {
var validatorUrl = "http://validator.w3.org/check?uri=http" + (document.URL).substring(5);
window.open(validatorUrl);
}
</script>
</head>
<body>
<h1>Test Template Page</h1>
<p><img src="valid-xhtml1.png" alt="Valid XHTML 1.0 Strict" height="31" width="88" onclick="validatePage()" /></p>
</body>
</html>
Notice how the validatorUrl variable trims off the "https" from the URL and instead uses "http". So I just circumvented using the HTTP referer header.
Hope this helps someone else.

It doesn't really makes sense to add an attribute to store the isListedIn list on your nodes just to retrieve it later, as d3 already does that for you.

Si se entiende que deseas que ocupe el 100% de alto (aunque así como lo configuras no va a darte el resultado que esperas), pero de que? mmm, no sé, pudiera ser de otro elemento anterior o de la ventana o el body, etc. No especificas. Tampoco le estás dando un ancho... y tienes inhabilitado background-size: cover;, lo suficiente para que no te funcione.
Bueno, como no les estas dando medidas de ancho y alto al contenedor que tiene por fondo la imagen, este elemento sólo va a abarcar el mismo espacio que ocupen los elementos inherentes (como el formulario), y como el formulario tampoco tiene medidas definidas, simplemente todo se reduce al espacio que está ocupando el texto (...contiene un formulario...).
Entonces, para cualquiera que sea el caso y/o medidas, lo ideal es que uses background-size: cover; y especificar el ancho y alto en que deseas que abarque en concreto (para el 100% de alto usa "viewport height", es decir height: 100vh;), así se ajustará la imagen al 100% del ancho o alto según se reajusten las dimensiones de la ventana o dispositivo, siendo siempre el lado más largo del contenedor el que queda al 100%, el otro quedará excedido, con el excedente oculto (esto procurará que siempre quede la imagen de fondo en toda el área del contenedor). No se debe ajustar al 100% de ancho y alto (con respecto a las medidas de la imagen) a la vez, porque si el dispositivo no tiene la misma proporción que la imagen, está se deformará quedando con un efecto "aplastado" o "alargado" que se ve muy, pero muy mal y poco (o nada) profesional.
NOTA: Ten en cuenta que si la relación del alto o ancho del contenedor, ventana o dispositivo es muy amplio (por ejemplo 1000px de ancho por 400px de alto, o 500px de ancho por 1200px de alto) y tu imagen mide 1200px de ancho por 800px de alto (por mencionar un ejemplo), nunca va a poder apreciarse la imagen completa o exactamente en su proporción.
También considera que si tienes una imagen de fondo en toda la ventana, tu formulario debería tener un fondo blanco, para que los textos sean claros y legibles, todo esto por uso y funcionalidad (es decir, para una buena UI/UX), ya que el diseño debe ser pensando en el usuario, y este te lo va a agradecer. Así que nunca pongas bloques de texto regular sobre imágenes de fondo.

If you perform <PERSON> function comparing elements you will find cases where the triangular inequality does not work.
Example:
0 0 0 10 10 10
and
5 5 5 0 0 0
scores 9 (using <PERSON> comparing elements)
While
0 0 0 10 10 10
and
5 3 5 7 5 2
scores 3
and
5 3 5 7 5 2
and
5 5 5 0 0 0
scores 4
so 9 > 3 + 4. So triangular inequality is not working here.
But if you operate with the sorting position of each element in it vector (aka ranking) triangular inequality is gauaranteed.
This happens beacuase of repetitions of elements within vectors.
We should call "Kendall tau ranking distance" to one of the algorithms and "Kendall tau distance" to the other

The only part I'm having trouble with is how to figure out the number of packets that were sent to the server from the client.
The data sent can be variable-length, so I can't just divide the total bytes received by a #define'd value.
We have to use asynchronous calls to do everything, so I've been trying to increment a counter with every FD_READ message I get for the server's socket. However, because I have to be able to accept a potentially large file size, I have to call recv/recvfrom with a buffer size around 64k. If I send a small packet (a-z), there are no problems. But if I send a string of 1024 characters 10x, the server reports 2 or 3 packets received, but 0% data loss in terms of bytes sent/received.
Any idea how to get the number of packets?
Thanks in advance :)

Is there a way to make DynamoDB or the script to put a timestamp with proper time (am/pm)? The only thing I could find was creation_time (boto3) but that's for the table. Any suggestions? Thank you.
My pipeline:
class DynamoDBStorePipeline(object):
def process_item(self, item, spider):
dynamodb = boto3.resource('dynamodb',region_name="us-west-2")
table = dynamodb.Table('x')
table.put_item(
Item={
'url': str(item['url']),
'title': item['title'].encode('utf-8'),
'stamp': item['stamp'].encode('utf-8'),
}
)
return item

bool validAreacode = false;
while(!validAreacode)
{
// start of actual code //
Write("Enter in the area code you want to call: ");
areaCode = Convert.ToInt32(ReadLine());
x = 0;
while (x < phoneAreacode.Length && areaCode != phoneAreacode[x])
++x;
if(x != phoneAreacode.Length)
{
validAreacode = true;
cost = phoneCost[x];
}
else
{
WriteLine("YOU MUST ENTER A VALID AREA CODE!");
}
}
This is the simplest solution for you (not so much changes in your code required). But your code still has the problems. Your program will be crashed if user tries to print any not digit character instead of area code.

Using
JsonIgnoreAttribute
on Id property like this:
using System.Text.Json.Serialization;
public class ProductResDto
{
[JsonIgnore]
public int Id { get; set; }
public string Product { get; set; }
}
Create Contract-layer for your application that will contain all
the OutCountract models. So your Contract model will not contain
Id property:
public class ProductResOutContract
{
public string Product { get; set; }
}
And utilize it like:
// GET api/<ProductController>
[HttpPost]
public async Task<IActionResult> Post(ProductReqDto model)
{
try
{
var product = await _context.Products
.OrderBy(b => b.Name)
.Where(w => w.Name == model.Name)
.Select(c => new ProductResDto
{
Id = c.Id,
Product = c.Name
}).FirstAsync();
// Grades
product.Grades = ''; // LOAD ADD. INFO (use product.Id like FK in DB)
// Description
product.Descriptions = ''; // LOAD ADD. INFO (use product.Id like FK in DB)
// Files
product.Files = ''; // LOAD ADD. INFO (use product.Id like FK in DB)
// Parameters
product.Parameters = ''; // LOAD ADD. INFO (use product.Id like FK in DB)
var productOutContract = ConvertToOutCountract(product);
return Ok(productOutContract);
}
catch (Exception e)
{
return NotFound();
}
}
private static ProductReqOutContract ConvertToOutCountract(ProductReqDto product)
{
var outCountract = new ProductOutContract
{
// Fill the properties;
};
return outCountract;
}
Returning Id is also not bad. You should just handle the model on
the frontend properly.
I prefer the 2nd or the 3rd solution. It's more clear when the API-layer and data-layer are separate.

sendAlertCont(data: any) {

How can I do the service function called sendAlertCont() returns a response sendig options in the data and getting the response in the component that sent the alert:
AnyComponent: send Data => AlertService: active Alert => AlertComponent: show alert & options
and then
AlertComponent: Send Response => AlertService: get & send response => AnyComponent: recives response

Compute p row by row and sum them up, and divide them by the batch size to get the avg p.
Compute p in one step: flatten all predictions as x and labels as y, and compute p = pearson_loss(x,y).
For example, for input:
X = [[1,2],[3,4]] and Y = [[-1,-2],[-3,-4]].
Compute first row, which is p1 = pearson_loss([1,2],[-1,-2]), and then second row, p2 = pearson_loss([3,4],[-3,-4]), and get avg p = (p1+p2)/2.
Compute p = pearson_loss([1,2,3,4], [-1,-2,-3,-4])
Does this two method have huge difference?
PS:
In Tensorflow, I defined pearson loss using Keras as followed (use Method 2):
def pearson_loss(x, y):
mx = K.mean(x)
my = K.mean(y)
xm, ym = x-mx, y-my
r_num = K.sum(tf.multiply(xm,ym))
r_den = K.sqrt(tf.multiply(K.sum(K.square(xm)), K.sum(K.square(ym))))
r = r_num / r_den
# ensure r is in range
r = K.maximum(K.minimum(r, 1.0), -1.0)
return -r

Yes, the install process is tedious, but it's worth it to get it done right.
This is for all Indy components except SSL. (I haven't tried any of the SSL stuff yet.)
A.) Seek and destroy all Indy files that come with Delphi. These are
no good as the Indy project is updated every single day with new bug fixes.
If Delphi picks up any of the old files instead of your new fresh Indy library,
you will get crazy errors from the IDE at all different times that are very hard to
trace.
i. Go to Component-->Install Packages, then completely remove all packages that start with "Indy".
ii. Close Delphi.
iii. Erase all files that match "dclIndy*.bpl" and "Indy*.bpl" from Delphi's Bin folder.
(C:\Program Files\Embarcadero\RAD Studio\8.0\bin)
iv. Erase all files that match "Indy*.dcu" and "Id*.dcu"^^^ in Delphi's Lib sub folders.
(C:\Program Files\Embarcadero\RAD Studio\8.0\lib\win32\debug)
(C:\Program Files\Embarcadero\RAD Studio\8.0\lib\win32\release)
^^^ Warning: watch out for non-Indy DCUs that happen to begin with the letters "id"
like "idispids.dcu" and "idoc.dcu"
v. Delete the entire Indy10 source folder:
(C:\Program Files\Embarcadero\RAD Studio\8.0\source\Indy10)
B.) Download the latest Indy10_XXXX.zip from http://indy.fulgan.com/ZIP/
(If you get a compile error or runtime error using this zip file for any of the steps
below -- don't be discouraged! Re-download the zip file on the following day and try
again. This zip file gets updated every day and there is a chance that there may be
some bugs/errors on any given day.)
C.) Extract only the System, Core, and Protocols folders into your own Indy library folder. ex.
(c:\MyDelphiComponents\Indy\Core)
(c:\MyDelphiComponents\Indy\System)
(c:\MyDelphiComponents\Indy\Protocols)
D.) Launch Delphi. Ignore all failed package dialogs: These are the Embarcadero packages
that rely on Indy! (Just click Ok on all errors, and indicate that any failed
packages should not be loaded again.)
E.) Go to Options-->Environment Options-->Delphi Options-->Browsing Path
- Remove paths that start with $(BDS)\Lib\Indy10
F.) Go to Options-->Environment Options-->Delphi Options-->Library Path
- Add your new System, Core, and Protocols folders from step C to Delphi's library path.
G.) Perform the following 5 actions in order:
(Just say OK to any dialogs about upgrading the project.)
Important:
After loading each dpk and before each build, go to:
Project-->Options-->Description-->Build Control
Set radio button to "Explicit Rebuild".
(Actually, this is optional, but I always make packages Explicit Rebuild
because they seem easier to handle that way, but I'd like to hear what
other people think about this...)
Build - System\IndySystem150.dpk
Build - Core\IndyCore150.dpk
Build first,
then Install - Core\dclIndyCore150.dpk
Build - Protocols\IndyProtocols150.dpk
Build first,
then Install - Protocols\dclIndyProtocols150.dpk
** Double check that you've set "Explicit Rebuild" on all packages! **
H.) Finally, go to Component-->Install Packages and find all of the packages that rely
on Indy that were turned off during step D. Reactivate them, and restart Delphi.
(If your new Indy hasn't changed too much from the one released with Delphi, those
packages will use the new Indy!)
++ Note, you may not receive any errors right away when reactivating those Embarcadero
packages, but they may pop up at random times later. For example, I just installed
Indy10_4548.zip and all the reactivated packages seemed fine. Then a day later out of
the blue, the IDE threw me a message that said it couldn't find GetRequestHeaders in
TIdCustomHTTP and that the dclWindowsAzureManagement150.bpl was having trouble as a
result. So I had to go back and disable that Windows Azure package in the IDE.

I would like to find the "best" parameter that would describe well data without overfiting it or underfiting.
Let $(x_i,y_i)_{i\in[1,n]}$ be a set of points such that $x_1 < x_2 <\dots < x_n$ . Once $\lambda$ is chosen the corresponding penalized spline curve $f$ found minimizes
$\displaystyle \sum_{i=1}^{n} (y_i - f(x_i))^2 + \lambda \int_{x_1}^{x_n} [f''(x)]^2 dx$
Basically $\lambda$ controls the trade-off between the goodness of fit and the smoothness of the fitted curve.
if $\lambda= 0$, $f$ interpolate data hence it overfits
if $\lambda\to +\infty$ the integral as too become smaller and smaller: $f$ obtained is a linear regression hence underfit data.
I would like to find a way to find the optimal value of $\lambda$ but I cannot use a $\chi^2$ tests otherwise the solution found would be $\lambda = 0$.
I found a criterion called cross-validated residual sum of squares (CVRSS) to minimize and the minimum corresponds to the best value $\lambda$ (Method described in Annex B of the following document http://curis.ku.dk/ws/files/<PHONE_NUMBER>/thesis_helene_rytgaard.pdf)
But it gives me a corresponding $f$ curve which overfit too much data in my case.
Many thanks in advance if you have a solution to propose to this problem

If you don't have much data then go with a Set Set<T> unique = new HashSet<>(yourList); (use LinkedHashSet if you care about the order. It creates a new collection, but usually it's not a problem.
When you want to modify existing list and don't want to/can't create a new collection, you can remove duplicates like here:
List<Integer> numbers =
new ArrayList<>(asList(1, 1, 2, 1, 2, 3, 5));
System.out.println("Numbers: " + numbers);
ListIterator<Integer> it = numbers.listIterator();
while (it.hasNext()) {
int i = it.nextIndex();
Integer current = it.next();
for (int j = 0; j < i; ++j) {
if (current.equals(numbers.get(j))) {
it.remove();
break;
}
}
}
System.out.println("Unique: " + numbers);
It works in O(n^2), but it works. Similar implementation, but simpler, is when the list is sorted - works in O(n) time. Both implementations are explained at Farenda: remove duplicates from list - various implementations.

int getAndUpdate(IntUnaryOperator updateFunction)
int updateAndGet(IntUnaryOperator updateFunction)
Both are using the updateFunction to perform update of the atomic value. The difference is that the first one returns old value and the second one return the new value. The updateFunction may be implemented to do more complex "compare and set" operations than the standard one. For example it can check that atomic counter doesn't go below zero, normally it would require synchronization, and here the code is lock-free:
public class Counter {
private final AtomicInteger number;
public Counter(int number) {
this.number = new AtomicInteger(number);
}
/** @return true if still can decrease */
public boolean dec() {
// updateAndGet(fn) executed atomically:
return number.updateAndGet(n -> (n > 0) ? n - 1 : n) > 0;
}
}
The code is taken from Java Atomic Example.

It's a script that calculates how long it will take to travel a certain distance.
At the moment it takes the numbers to be divided from text boxes on my page. It seems to do the division but the result isn't correct.
For example...
var a = 3.7 (distance) and var b = 25 (speed)
function journey_calc()
{
var a = +$("#txtDistance")[0].value; // example: 3.7 miles (distance)
var b = +$("#txtSpeed")[0].value; // example: 25 mph (speed)
var c = (a/b)/3600000; // returns the length of time it will take to travel the distance in hours, then divides by 3600000 to get the answer in milliseconds.
$(".journey-finder-result").text(c); //posts answer to span on page
}
It "works" but "var c" is calculated incorrectly. Using the example above the answer should be 532800, but it returns 4.111111111111112e-8
The end goal is to convert the milliseconds into dd:hh:mm:ss form - am I approaching this incorrectly?
Many thanks!
Note: I am a newbie to javascript so I'm probably missing a very simple mistake!

Then consider the two HSV colours h1 = (156, 0.625, 0.8) and h2 = (300, 0.6, 0.5) and convert them into RGB (giving r1 and r2), CMY (c1, c2), and CMYK (k1, k2). Finally, compute the linearly interpolated colors h3 = 0.3h1 + 0.7h2 and r3 = 0.3r1 + 0.7r2 and compare them after having converted r3 into HSV.
I have found the formula from the Wikipedia but I don't know what I have to do in order to get the correct result. I am confused with the CMY and CMYK and the linearly interpolated colors I have to compute too. So any help will be greatly appreciated.

I want to suppress this warning. But the command line option /wd only forks for Cxxx errors and warnings, not Dxxx warnings. How do I suppress the D9025 warning?

The error that is produced depends on whether multiple partitions have been specified or not.
I understand that
the two RDDs [must] have the same number of partitions and the same number of elements in each partition.
What is the best way to work around this restriction?

nm -g lib/linmqttpp.so.0.1
You will see it is empty.
Also if you copied and passed the example code from the website then it will not work. It needs other code beside what is on the website. It just gives you a code snippet.
Example code is in this directory.
src/samples
paho c++ examples
Currently the make file for the sample files will fail.
I have submitted a patch just now to the project to fix the main build and the sample files build. Once that is applied the project will build correctly you can start hacking the sample files.
With regards the C++ project not installing its because there is no target in the make file to do an install. if you want for now copy the files that are created in lib to the below with sudo permissions.
/usr/local/lib/
Then you can access the shared libraries from any project.

I'm trying to code a lexer and parser for computer algebric system.
When I'm compiling the code with my makefile, I have problems on the value of some functions.
Here is the code of function.ml :

let parse_eqn = eqn_of_string;;
let parse_expr = expr_of_string;;
The problem is that in the parser.mli which is create with the makefile, the value of yacc_eqn and yacc_expr are :
val yacc_eqn :
(Lexing.lexbuf -> token) -> Lexing.lexbuf -> Function.eqn
val yacc_expr :
(Lexing.lexbuf -> token) -> Lexing.lexbuf -> Function.expr
And I have the following error :
The implementation parser.ml does not match the interface parser.cmi:
Values do not match:
val yacc_eqn :
(Lexing.lexbuf -> Function.token) -> Lexing.lexbuf -> Function.eqn
is not included in
val yacc_eqn :
(Lexing.lexbuf -> token) -> Lexing.lexbuf -> Function.eqn
I think the solution might be to something like a cast, but I have stricly no idea how to do that ... Anyone help ?
Thanks in advance !

To do that, I'm parsing the input, I'm tranforming the input into a data structure.
I'm currently trying to create an ocaml function to simplify at maximum this input.
For example, x*x - x*x will simplify in 0
Here is my parser :
%{

;

| SQRT LPAR expr RPAR { sqrt $3 }
| LN LPAR expr RPAR { lnp $3 }
| EXP LPAR expr RPAR { expo $3 }
;
Here is my lexer :
{
open Parser
exception Eof
}
rule token = parse
| [' ' '\t'] { token lexbuf }
| ['\n'] { EOL }
| ['0'-'9']+ as lxm { FLOAT (float_of_string lxm) }
| '+' { PLUS }
| '-' { MINUS }
| '*' { TIMES }
| '/' { DIV }
| '(' { LPAR }
| ')' { RPAR }
| '^' { PUIS }
| "cos" { COS }
| "sin" { SIN }
| "sqrt" { SQRT }
| "ln" { LN }
| "exp" { EXP }
| ['a'-'z']+ as lxm { VAR (lxm) }
| eof { raise Eof }
I think my parser and my lexer are good.
Then, I'm using a tree to store the function :
type formel =
| Float of float
| Var of string
| Add of formel * formel
| Sub of formel * formel
| Mul of formel * formel

For simple function as x*x + x*x, this function works.
But if I enter the function : 2 + x*x - x*x, there is no simplification done. The result is : 2 + x^2 - x^2
I have no idea how I can fix this problem, I'm on it since 3 days.
I hope everything is clear, and someone can give me some tips !
Have a great day !

//create a multichannel matrix
Mat a_com = Mat<IP_ADDRESS>zeros(4,4,CV_32FC2);
for(int i = 0; i<4; i++)
{
for(int j = 0; j<4; j++)
{
a_com.at<Vec2f>(i,j)[0] = a.at<double>(i,j);
a_com.at<Vec2f>(i,j)[1] = 0;
}
}
MatrixXcf eigenA;
cv2eigen(a_com,eigenA); //convert OpenCV to Eigen
ComplexEigenSolver<MatrixXcf> ces;
ces.compute(eigenA);
cout << "The eigenvalues of A are:\n" << ces.eigenvalues() << endl;
cout << "The matrix of eigenvectors, V, is:\n" << ces.eigenvectors() << endl;
This gives me the following output (which is more or less what I was looking for):
The eigenvalues of A are:
(0.3951,-1.89571)
(0.3951,1.89571)
(0.3951,1.89571)
(0.3951,-1.89571)
The matrix of eigenvectors, V, is:

I have a new dataset which I know has a very unbalanced class distribution, but I don’t know anything about this distribution, so I use a uniform prior distribution for my classifier. Because my classifier is a good discriminator, the output posterior distribution is much closer to the actual distribution of the dataset than the uniform distribution that I originally assumed.
My understanding is that in the next experiment with similar parameters, I can use this posterior distribution as the prior to improve the classification output. My question is: can I also use this posterior distribution with the original dataset to improve the output?
I’ve actually done this using a neural network as a classifier with thresholding according to <PERSON>’ theorem (essentially, prediction thresholds are proportional to the given prior distribution). Running prediction with uniform priors to get a posterior probability distribution, and then re-running prediction with that new distribution as the priors yields much better results compared to using just the uniform distribution. In fact, doing this over and over again recursively until predictions converge yields the best results, and comes extremely close to predicting the actual class distribution of the dataset.
I hope this question makes sense — I’m fairly new to probability theory so I’m mainly concerned with whether or not this approach is valid, or if my results are somehow spurious.

https://support.apple.com/en-gb/HT201478
Find the section "Organise your library" then scroll through to the sub-category called "Create, view, and organize collections."
The following is the part that will sort it out:
"To automatically sync your Collections with your other devices, sign in to all of your devices with the same Apple ID. Then, on your iPhone, iPad, or iPod touch, go to Settings > iBooks and turn on Sync Collections."
If in future you wanted to reverse this and sync all of your collections FROM your Mac to your iPad, this is what you'd do:
"To sync from your Mac, choose iBooks > Preferences from the menu bar at the top of your computer screen. Click the General tab, then select "Sync bookmarks, highlights, and collections across devices." "
NOTE - if you have the "Sync Collections" option turned on on your iPad AND on your Mac at the same time IT WILL NOT WORK. Choose one or the other.
Hope this solves it for you!

However, I have a requirement for one of the tables to display a different highlight color on row select. I had been trying the below but obviously it isn’t working.
In my style-sheet:
#lightHighlightTable .table-view .table-row-cell:selected {

How to verify authenticity of permission of an IP to be used by an AS, and the AS itself is the problem.
RPKI is one attempt to improve the situation, but its adoption is still very low.
I'm guessing ARIN and the other RIR don't want to get involved in publishing IP to ASN number mappings because it's a lot of data and they don't want to be in the business of serving and managing all that data. I think RPKI allows some of the data to be distributed, in a hierarchical manner similar to DNS, therefor making the system more scalable.

I think the bottom line is that you need to have all routers in your route knowing about the route, otherwise it doesn't work. You can do BGP peering only with your directly connected peers. Is this correct? |

I hadn't noticed this however because I had only been using the Cordova Tools project to compile for Windows 8.1 / 10 devices and in these build configurations the package naming convention is not enforced
This caused the problem:

Have tried Nexus 5, Samsung Galaxy Tab 2 and various emulators. All devices have been used as debug targets before

I can debug OK on Windows Phone 8.1, Windows 10
If I try and deploy the APK created from the console with ADB:

I have tried clearing the cache, checking the dependencies (both in Options) and checked for updates.
Any suggestions on how to move forward?

Configure connection string to use new server
Run Update-database command from package manager console, in some cases you will need to use -force flag. But be careful this could delete some your data. Also this command has - ConnectionStringName parameter this could help you to make updates.
This is a very bad approach and I don't recommend update database this way.
I would recommend you set up Initialzier for your context. I usually use MigrateDatabaseToLatestVersion and after changing your model you will need to add new migration, using Add-migration command.
To set up it use this command in application start method:
Database.SetInitializer<ApplicationDbContext>(new MigrateDatabaseToLatestVersion<ApplicationDbContext>());

And than use this abstraction in your code
public class MyRepository

public MyRepository(IApplicationSettings settings)
{
this.conncetionString = settings.ConnectionString;
}
}
In this way you will hide any dependency to stuff like ConfigurationManager and the way how you storing settings in app. If your are using IoC, you will have control on instance life time.

The problem I am having is that my month and item values are not clearing and end up nesting themselves back into the previous month as well. I believe I have pinpointed where the flaw in logic lies but I can't seem to fix it. Any help woould be appreciated. My function looks like so...
function buildBooklistArchive( $, response ) {
var years = [];
response.forEach( function(el) {
var yearContainer = $("<ul>");
var year = $("<li>").addClass("year-" + el.YEAR);
var monthContainer = $("<ul>");
var month = $("<li>").addClass("month-" + monthConverter(el.MONTH) );
var titleContainer = $("<ul>");
var currentMonth = "";
if ( $.inArray(el.YEAR, years) === -1 ) {
years.push(el.YEAR);
currentMonth = monthConverter(el.MONTH);
year.append("<h1>" + el.YEAR + "</h1>");
month.append("<h4>" + currentMonth + "</h4>");
var titles = el.booklists.split(",");
titles.forEach( function (e) {
titleContainer.append(e);
});
month.append(titleContainer);
monthContainer.append(month);
year.append(monthContainer);
$(".archive-list").append(year);
}
else {
currentMonth = monthConverter(el.MONTH);
month.append("<h4>" + currentMonth + "</h4>");
var titles = el.booklists.split(",");
titles.forEach( function (e) {
titleContainer.append(e);
});
month.append(titleContainer);
$( '.year-' + el.YEAR + ' ul' ).append( month.hasClass("month-" + currentMonth) );
}
});
}
So whats happening is that when I get into the else statement month is still holding the value of the previous month and attaches iteself into the bottom of the previous list items. My thinking would this variable would get reset upon each iteration of the loop but maybe its different for DOM elements? The output I am getting looks something like this..

Finally got the workflow down, finished two related projects, and I was going to start tinkering with the code. But I found AzerothCore, and I'm very intrigued. Got a few questions about the differences between it and TrinityCore.
First off, AC is advertised as having a modular design, which is brilliant. TC has a single instance of modularity with it's script system, which is also very good; edit the C++ source script, save it, and the server will reload it at runtime without having to recompile the whole server. Is that functionality also present in AC? And how robust is the module system?
My reason for asking is that I want to add more dynamic features rather than focusing on instances, phases, and quests that are repeatable by every single character. The first step for that, would be to change the AI scripting system. So rather than having one monolithic script attached to an NPC, an array of scripts arranged in a hierarchy with conditions that are processed periodically would be a great first foray into the actual code base. Would it be possible to contain that functionality in a replacement module?
Another question I have, is regarding the prevalence of bugs. TC's development does seem a touch slow, and it's community not all that active. How is AC's development in regards to the robustness of the low level systems? With TC, for instance, every so often there would be floating NPCs making their way around Goldshire, which is a rather immersion-breaking bug. Does AC have similarly obvious bugs?

I need the icons/labels to show up on both map types at the same zoom level.
I've tried this with both the google maps API v3 as well as the static map URL formulation and the same problem shows up. It appears the server determines that at certain zoom levels of the HYBRID map certain icons/labels should be hidden. I would like to override this decision. Is there a mechanism for this?

i.e.:
ipmitool -I lanplus -U root -H <server> -P <password> chassis power status
If you're using QEMU, then I believe you need to hostfwd port 623 for this to work. I personally have not gotten ipmitool to talk to a QEMU session before though.

You could receive BUFFER_SIZE - 1 bytes and then set buffer[bytes_recvd] = '\0' before doing your tests.
Also, as others have pointed out, you need to look for "\r\n\r\n" instead of "\n\n" as the termination of your headers.
Be careful to handle the condition where the CR LF CR LF sequence crosses two different recv() calls. One possible workaround to this possibility would be to copy the last three bytes of buffer to the start of buffer, and have your next read begin at &buffer[3].

Further breaking down what they said; unless the current of the DC signal surpasses the current of the AC signal, the ONLY difference in coil heating would be the time during each quarter of the AC cycle that the signal is not at full amplitude. However, all but the cheapest speakers are designed with a LOT of room for overcurrent situations, so unless you are running the thing hot enough that the AC current ALSO burns the coil, the DC signal should be particularly damaging. It is the extreme stress at the start of the dc pulse that harms it. |

Your examples are somewhat biased, since you've selected researchers who were not only brilliant but also prodigies. By contrast, <PERSON> finished his Ph.D. dissertation at the somewhat older age of 25, and <PERSON> didn't start his research career until he was 39 or so. Brilliant researchers are more likely to get an early start than average researchers are, but the correlation is far from perfect. Focusing on prodigies gives a misleading picture.
There are plenty of prodigies today (<PERSON>, <PERSON>, <PERSON>, <PERSON>, etc.). If they occupy a smaller fraction of academia, it's probably because academia has grown enormously even relative to the population. The faculty in the top departments today are stronger on average than a hundred years ago, but there are many more departments nowadays, so the average professor is overall probably not as talented.
The amount that's known is steadily increasing, so getting to the 19th century research frontier takes quite a bit less time than getting to the 21st century research frontier. This is not as relevant in very new fields, but finishing a Ph.D. in algebraic geometry in two years is a more impressive feat today than it was a hundred years ago. This increase in knowledge doesn't translate perfectly into an increase in time to degree: people also compensate by specializing more and then broadening later in their career. However, the obstacles to a quick Ph.D. are certainly increasing over time.

Here are the interesting tables and columns of my database schema for this problem.(I did not include the user table, as the only relevant column is the id column).
`ActiveRecord<IP_ADDRESS>Schema.define(version: 20140430100754) do
create_table "bookings", force: true do |t|
t.integer "spot_id"
t.integer "user_id"

t.integer "owner_id"
t.string "address"
end
create_table "spots", force: true do |t|
t.integer "parking_id"
t.string "number"
end
end`
At the beginning the booking system was simple: A user would book a spot with a start time and an end time, and when querying for available spots, I would take the existing bookings into account.
However, I now have to add availabilities on each spot: The owner of one parking spot must be able to set for each day of the week when his/her spot is available. I have done some research on how to store this in the database, but I did not find anything approaching. (Only simple booking systems like my previous system)
Here are the main issues I have to address:
The granularity of the booking system must be of 15 minutes at least
I have to query very often the database to find all the parkings that still have at least one available spot for a given timeframe.
My first question is about the way to store the initial availability infos.
The only solution I could think of is storing it using booleans for each 15 minutes timeframe (with that for seven days, it is 672 columns, does not seem a groundbreaking idea to me). So do you have any advice on how to store this, and how to query this in an efficient way to check availability ?
My second question is about the booking table:
I want to clean the booking table in order not to let it grow, (I'm afraid it will slow down the queries to check availability on spots and parkings) BUT keep track of the previous booking by storing it in another table (which I won't query very often). Is it a good approach or not ?
Notes
I stated I'm using Ruby on rails, but I think the issue is language independent, and much more a database design issue.

How do i switch off the built in laptop monitor after x minutes or when the lid closes (or both).

The former lets you validate the value of a given field data, independently from others. The later allows you to validate your form by taking into account several fields value. So it's normal that the outcome of writing your "validation code" in either the first or second method is different.
Have you tried to follow Django documentation about this subject?
As you will see in this doc, calling super.clean() at the end of a field validation method does not make much sense as it will be called anyway during the whole validation process. This method (for example clean_new_password_2()) should be constructed as follows:
def clean_new_password2(self):
old_value = self.cleaned_data['new_password_2']
new_value = ...
return new_value # this is the value you want for this field
From what I understand from your use case, your code should be:
def clean(self):
cleaned_data = super().clean()
... # Do here the validation stuff you want to do with your field values
# and if you changed the values of ones of the field in cleaned_data, do as follows:
return cleaned_data # you can even return whatever you want
# If you changed nothing, you don't need a return statement

I have a view (APIView) which can only be accessed by some users who successfully pass a given HasUnlimitedAccesPermission check. In case of failure to pass the latter, I raise a PermissionDenied with a detailed message of my choice about the error to pass on to front-end. So far so good, all of that is easily achievable by applying the HasUnlimitedAccessPermission to my view thanks to the "permission_classes" decorator (yeah, I'm using a function_based view, here).
Now, what I would like to achieve is passing an additional attribute to my error response JSON (when the user fails to pass the permission test). This attribute would be an "error_id" attribute that would give the front-end developer the ability to adapt the error display depending on the "error_id" value. An example of the response JSON would be :
{
"error": "To enjoy this feature, go pick one of our pay offer!",
"error_id": "no_unlimited_access"
}
Any idea on how to achieve this?

My understanding is that it factors the effect of the absorbed parameters out of the data before estimating the remaining parameters. It seems like this may invalidate the standard errors of the parameter estimates. The variance covariance matrix would not be calculated with the full set of parameters. Hence, we would be calculating the variance covariance matrix conditional on the absorbed parameters, where we would really want the unconditional variance. Am I misunderstanding what is going on here? I haven't found any good explanations in the help files.

Basically you can achieve this by setting a remote server that waits for N connections to be done (you can do a basic user/password login for this), then once all required users are connected you can create an account on some webmail server that has his own exposed API (i guess gmail has it's own)
the main point is that if you 3 are sharing a key and you don't want other login without your permission, no one should own that host and no one should ever join in, because the owner could change the code and save some sensible data.
but i think there is some nasty point after that: how could you set the phone number of that account on the convalidation?
you could also activate account security if webmail server has it but that require that you have that account on your mobile phone and this doesn't prevent access without permission
-----
EDIT: if you want just to remote type in the password, you could use TeamViewer too, i think it's keylogger proof and you can use Avast virtual keyboard to be much more safer

Your comment helped me out a lot in places that I had trouble with before. One issue that I am coming across, however, is the problem that although I am running the server on my computer, and localhost works, other computers on the same network are not able to see what I see. What I tried is:
* ran the server on my machine.
* copied the ip address of my machine (<IP_ADDRESS>).
* pasted that into another machine on the same network.
It turns out that that approach times out, which is different from what I expected would happen. | 6405c3d65f159b8f8c6392072078702c3edb24d633df79a0b64226f5ab77ff85 | ['581bcfcdc6164b90a46f8668d4275abb'] | I am an almost absolute beginner to the world of servers. I have no knowledge of setting up a server aside from running apachectl -k start and seeing "it works!" in localhost. I've tried dabbling in "port forwarding" and tried to get something to work in no-ip.com, but after a while I had no idea what I was doing. If it means anything, the process I tried through no ip was:
port forwarding the http port on my laptop through my router (this is how it looks
running apache
running the noip client
creating a host on noip (with settings DNS Host(A), and whatever IP address it detected)
accessing the domain created by no-ip.
What ended up happening was when I tried accessing the domain (which by the way is swarajd.no-ip.org), it times out. I recognize that I am doing something wrong but I do not know what to do in order to remedy the mistake.
I want to be able to set up a simple web server on my laptop running openSUSE, through my verizon actiontec MI424WR router, on a simple domain name such as swarage.somewebsite.info or something.

This was due to me having problems with having async functions inside the message listener, even with "return true", it was throwing message port closed before response received error.
This is the final code in background script:
const FETCH_METRICS =
[
'commits', // 0
'issues', // 1
'branches', // 2
'pullrequests' // 3
]
async function fetchData(type, aux)
{
let url_fetch = `${url_base}/${type}/${aux}`
try
{
return (await fetch(url_fetch)).json()
}
catch (err)
{
console.log('Error: URL = ', url_fetch, ' err: ', err)
}
}
async function execute(request, aux)
{
const data_ = await Promise.all(FETCH_METRICS.map(type => fetchData(type, aux)))
return data_
}
chrome.runtime.onMessage.addListener((request, sender, sendResponse) =>
{
chrome.storage.sync.get('oauth2_token', (res) =>
{
if (res.oauth2_token != undefined)
{
chrome.tabs.query
({
'active': true, 'lastFocusedWindow': true
},
function (tabs)
{
let url = tabs[0].url.split("/")
let owner = url[3]
let repo = url[4].split("#")[0]
let url_aux = `?owner=${owner}&repository=${repo}&token=${res.oauth2_token}`
execute(request, url_aux).then(sendResponse)
})
}
})
return true
})
and this is the contentscript (already plotting the charts, response is now defined and filled with the correct data):
if (typeof chrome.app.isInstalled !== 'undefined')
{
console.log("gbdScreen sending requests")
chrome.runtime.sendMessage({metric: "get-metrics"}, function(response)
{

{

Due to that, I am doing all the requests from inside a background script, and trying to communicate between the backgroundscript and contentscript using the message API. Whenever I'm ready to use the data inside the contentscript, I send a message to the background script, which will then fetch the data from the API and send it as a response to contentscript. From the background script, if I console.log the data right before I send it, it's all good (an array of 4 positions). However, the received data in the contentscript is an empty array, all the data stored in the array is lost.
Here's the contentscript code snippet that sends the message:
if (typeof chrome.app.isInstalled !== 'undefined')
{
console.log("gbdScreen sending requests")
chrome.runtime.sendMessage({metric: "issues"}, function(response)
{
setTimeout(function(){
if (response !== undefined)
{
console.log(response)
console.log(response.data)
}
else{
console.log("gbdScreen-else")
document.getElementById('gbdButton').click()
}
}, 2000)
})
}
And here's the background script, in which it receives the message, proceeds to fetch the data, and sends it back:
chrome.runtime.onMessage.addListener(function(request, sender, sendResponse)
{
let arr = []
chrome.storage.sync.get('oauth2_token', function(res)
{
if (res.oauth2_token != undefined)

({
'active': true, 'lastFocusedWindow': true

{
let url = tabs[0].url.split("/")
let owner = url[3]
let repo = url[4].split("#")[0]
let url_aux = `?owner=${owner}&repository=${repo}&token=${res.oauth2_token}`
let url_fetch = url_base + '/commits' + url_aux
// async function to make requests
const asyncFetch = async () => await (await fetch(url_fetch))
// commits request
asyncFetch().then((resp) => resp.json()).then(function(data)
{
arr[0] = data
}).catch(function(err)
{
console.log("Error: URL = " + url_fetch + "err: " + err)
})
// issues request
url_fetch = url_base + '/issues' + url_aux
asyncFetch().then((resp) => resp.json()).then(function(data)
{
arr[1] = data
}).catch(function(err)
{
console.log("Error: URL = " + url_fetch + "err: " + err)
})
// branches request
url_fetch = url_base + '/branches' + url_aux
asyncFetch().then((resp) => resp.json()).then(function(data)
{
arr[2] = data
}).catch(function(err)
{
console.log("Error: URL = " + url_fetch + "err: " + err)
})
// prs
url_fetch = url_base + '/pullrequests' + url_aux
asyncFetch().then((resp) => resp.json()).then(function(data)
{
arr[3] = data
}).catch(function(err)
{
console.log("Error: URL = " + url_fetch + "err: " + err)
})
console.log(arr)
sendResponse({data: arr}) // sends back to screen.js the data fetched from API
})
}
})
return true
})
I console.log inside both the backgroundscript and the contentscript, and it's all good in backgroundscript, but printing an empty array in contentscript. If anyone can shed some light, I know it's pretty messy code right now.

User list - GET /users.json
users: [
{id: 0, name: "<PERSON>"},
...
]
Users by Id - GET /users/0.json
user: {
id: 0,
name: "<PERSON>"
}
As you can see, if you first request the data from the list (/users.json), and then click on a user, even though the information was present in the first list, it is re-requested from the user by id request.
In Falcor, this would be solved by having a list of references in the first call.
My question is, if I am writing a Falcor router to act as a middleman, how do I optimise such a scenario? Currently, the router has to request the full user list, and then throw out the information and return a list of references based on the ids to the client. This still saves bandwidth on the client side but is suboptimal between the Falcor router and its datasource (REST API).

$-(-\Delta)^{\alpha/2}$ for some $\alpha \in (0, 2]$ under $\mathbb P$. Let $\mathbb P^x$ be the probability measure induced by a process

starting from $x$, and we set
$$\hat \zeta = \inf\{t>0: X(t) \notin (-1, 1)\}, \quad
\zeta = \inf\{t>0: X(t) \notin [-1, 1]\}.$$
My question is that
[Q.] Is $\mathbb P^x (\hat \zeta = \zeta) = 1$ valid for $\alpha \in (0, 1)$?
[remark]
The answer should be positive if $\alpha \ge 1$. In fact, one can use strong <PERSON> property and time-shift operator to obtain
$$\mathbb P^x(\hat \zeta = \zeta) =
\mathbb P^x (\zeta \circ \theta_{\hat \zeta} = 0) =
\mathbb E^x [ \mathbb P^{X(\hat \zeta)} (\zeta = 0)] = 1.$$
The last equality is true, since $\zeta = 0$ $\mathbb P^{x}$-a.s for all $x\notin (-1, 1)$ when $\alpha\ge 1$.
However, when $\alpha <1$, $x = -1$ is not regular to $[-1, 1]^c$, i.e. $\zeta>0$ holds almost surely in $\mathbb P^{-1}$. Therefore, the above argument does not work any more, unless $\mathbb P^x(X(\hat \zeta) = -1) = 0$, which is not clear to me.
Thanks.

I know it's long, but I would appreciate it if someone could let me know what's wrong with my program. There is no traceback.I'm getting the notification from Stack Overflow that my post is mostly code, but there's really not much more to say about the problem. Also, I have looked at many questions talking about this and have not found an answer in any of them that I can use. Thanks in advance!

Made an jsfiddle so you guys can take a closer look.
It looks good on Chrome, on other browsers you need to modify the colors abit. Like in Firefox you need too change the color and Background-color to etc.

You can find the setup.txt here:

So I guess you must include
<INCLUDE_TYPOSCRIPT: source="FILE:EXT:css_styled_content/Configuration/TypoScript/Helper/StylesContent.txt"> where getLeft, getRight and getBorder is definded.
Alternatively you can just add this one line after
ASSIDE < styles.content.getRight
ASSIDE.select.where = {#colPos}=2
or as I know it from that templating time ASSIDE.select.where = colPos=2
Well, but as <PERSON> already recommended you should anyways switch to FLUIDTEMPLATE but getting the column not directly depends on that. I also just want to make you know that FLUID is the right thing.

There are two classes:

Just replace the two classes with variables and set the width you want at the top of your .js. Do not use % for dww, this will not work.

This seems to be a standard manga or dorama style declaration of the speaker's feelings for another person お慕い申しております (the sentiment) and 気持ちをお伝えしたくて (the confirmation of the speaker's desire to convey said sentiment)
Request -- if the other person would agree もしよかったら -- for "the person's hand in marriage", since official documents are traditionally exchanged, as in a contract or, at least, here, a formal vow, an "eternal promise", i.e. 永遠の契り (which in a different context may connote a more spiritual, even religious commitment).
This declaration/request/"confession" (depending on context) is followed by another standard leitmotif found in manga/dorama, whereby the declaration itself is considered (by the possibly embarrassed speaker -- and perhaps in light of social norms) as an impulsive, or even premature, unexpected revelation of the speaker's private sentiments, even a betrayal of the speaker's own sense of dignity. [Abrupt interruption of declaration/request] あぁー 私 (わたくし)ったら、もう何を言ってるんでしょうか？

For example:
list of subject lines
I want to understand if there is influence for some words on the average open rate.
For example, maybe if I’ll write in the email subject line the word “Thanks”, the email open rate will be higher.
If I understand correctly the logical steps, I need to build list of all the words that are in the emails subject line, and for each word to do average between all the subject lines.
For example:
average per word
Can someone help me to do it with R? I think there is text mining packages that can help.
Thanks!!!

I am creating a simple email app where users can use smtplib module to log in and then send an email. I implemented a callback function that constantly check the user how many words the user has entered in the text entry box, then I update it in the self.Textlength label. Everything works fine but I notice the label doesn't update on the same callback event, I need to trigger the callback event again to update the label text. Is there a way to update the label instantly on the same callback event and not wait for another?

First I created a number recognition logistic regression model and it seem to work fine. But then I decided to test a random image myself, so I used OpenCV module to opened a picture that I randomly select from online (Shown below). The shape of the image is (425,425,3). I turned them into grayScale and threshold it. Then I try to predict it using the model I just created. But I got a "ValueError: Found array with dim 3. Estimator expected <= 2." I tried to use resize, reshape function to my image to match the array size but never seem to work, anyone can help me to solve the problem?
