The simplest solution is to just load geometry using variables, and then add a switch for \newgeometry just under the draftver that users can comment or uncomment to see the boxes. I ended up using this.
Class file:
\newcommand\leftMargin{1.2in}
\newcommand\rightMargin{1.0in}
\newcommand\bottomMargin{1.0in}
\geometry{letterpaper,
left= \leftMargin,
right=\rightMargin,
bottom=\bottomMargin
}
Main.tex:
\renewcommand{\draftver}{1.0}
% Uncomment this line to show boxes around margins for positioning
%\newgeometry{left=\leftMargin,right=\rightMargin,bottom=\bottomMargin,showframe}
That way, it doesn't matter what visual changes the draft makes, and I still have one location for changing margins. While that doesn't directly answer my question, it gets the job done!

I have set the width for each column, but somehow it treats the numbers like ratios. If I define 2 columns with the same width value, the columns will have 50% width.
For example,
columns.Bound(p => p.column1).Width(40);
columns.Bound(p => p.column2).Width(40);
would be rendered the same way like
columns.Bound(p => p.column1).Width(100);
columns.Bound(p => p.column2).Width(100);
So, if the columns have 20 and 30, the columns would 40% and 60% of the width respectively.
Considering that I have set the width for each column, what do I miss?

The easing functions I've seen so far are: ease, ease-in, ease-out, ease-in-out.
ease seems pretty similar to ease-in-out, which slows the animation at the beginning and end. I kind of want the opposite of that.
I'm creating a javascript animation to animate properties that can't be animated by css, such as linear-gradient.

I finally achieved the desired functionality adding a new field/column to the Datatable and instead keeping just one value for the entire row in that field, I store string representing the state/style for each cell like ",,E,,,E" so this sample string would indicate that the cell at index 2 and 5 should have an edited style.
I create/change that string in the CellValueChanged event, sample:
Private Sub DataGridView_CellValueChanged(sender As System.Object, e As DataGridViewCellEventArgs) Handles DataGridView.CellValueChanged
If e.RowIndex = -1 Or IsNothing(DataGridView.CurrentCell) Then
Return
End If
Dim cellPosition As Short = DataGridView.CurrentCell.ColumnIndex
Dim Styles(25) As String
Dim stylesCell = DataGridView.Rows(e.RowIndex).Cells("CellStyleDescriptor").Value
If Not IsDBNull(stylesCell) And _
Not IsNothing(stylesCell) Then
Styles= Split(stylesCell, ",")
End If
If IsDBNull(DataGridView.Rows(e.RowIndex).Cells("Id").Value) Then
For i As Integer = 0 To 25 'New row is being added
Styles(i) = "N"
Next
Else
Styles(cellPosition) = "E" 'Edited/Modified Cell
End If
DataGridView.Rows(e.RowIndex).Cells("CellStyleDescriptor").Value = String.Join(",", String)
End Sub
and read/apply the styles in the CellFormatting event, sample:
Private Sub DataGridView_CellFormatting(sender As System.Object, e As DataGridViewCellFormattingEventArgs) Handles DataGridView.CellFormatting
If e.RowIndex = -1 Or e.ColumnIndex = -1 Then
Return
End If
Dim styles(25) As String
styles = Split(DataGridView.Rows(e.RowIndex).Cells("CellStyleDescriptor").Value, ",")
Select Case styles(e.ColumnIndex)
Case "E" 'Edited cell

Standard read/write lock allows either multiple readers or single writer to run concurrently. I need a variant that can allow multiple readers or multiple writers concurrently. So, it should never allow a reader and a writer concurrently. But, its okay to allow multiple writers at the same time or multiple readers at the same time.
I hope I was clear. I couldn't find any existing algorithm so far. I can think of couple of ways to do this using some queues and etc. But, I dont want to take a risk of doing it myself unless none exists.
Do you guys know of any existing scheme?

I have identified a busy loop in my Linux kernel module. Due to this, other processes (e.g. sshd) are not getting CPU time for long spans of time (like 20 seconds). This is understandable as my machine has only single CPU and busy loop is not giving chance to schedule other processes.
Just to experiment, I had added schedule() after each iteration in the busy loop. Even though, this would be keeping the CPU busy, it should still let other processes run as I am calling schedule(). But, this doesn't seem to be happening. My user level processes are still hanging for long spans of time (20 seconds).
In this case, the kernel thread got nice value -5 and user level threads got nice value 0. Even with low priority of user level thread, I think 20 seconds is too long to not get CPU.
Can someone please explain why this could be happening?
Note: I know how to remove busy loop completely. But, I want to understand the behaviour of kernel here. Kernel version is 2.6.18 and kernel pre-emption is disabled.

In case of pointewise convergence of the series, I know that the series converges pointewise at the value $$\frac{f(x_+) + f(x_-)}{2}$$
But in the points of discontinuity, the function may not assume exactly that medium value, for example a function that is equal to $x^2$ in $(0,2\pi)$ and 0 in $x=2\pi$, in this case, in the discontinuity points, the series converges at a function that is not equal to the initial function. Maybe can I say the same that the series is equal to the initial function? Or not?
There are some conditions to know when the function is exactly equal to the series?

I need to configure the Firewall using iptables to port forward incoming ssh connections from my remote client (on the Internet) to the server (on <IP_ADDRESS>). Essentially executing ssh user@<IP_ADDRESS> on the client to remote into the server on <IP_ADDRESS>.
The Firewall has two NICs to communicate:
<IP_ADDRESS> (public) is on interface ens33
<IP_ADDRESS> (private) is on interface ens37
The Server has the private IP of 192.168.1.2 and has been configured to use port for 54045 for SSH, not the default 22.
Iptables on the Firewall has been configured that both chains INPUT and FORWARD have been changed to the policy DROP, the chain OUTPUT still has the default policy ACCEPT.
Chain INPUT (policy DROP)
target prot opt source destination
Chain FORWARD (policy DROP)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
I have seen some guides online detailing how to port forward web requests to a web server behind a firewall, see:
https://www.systutorials.com/port-forwarding-using-iptables/
https://www.digitalocean.com/community/tutorials/how-to-forward-ports-through-a-linux-gateway-with-iptables
https://wikileaks.org/ciav7p1/cms/page_16384684.html
Following these tutorials I have enabled port forwarding on the Firewall via the /etc/sysctl.conf file and tried the following rules:
1st Attempt
INPUT and FORWARD policy DROP, OUTPUT policy ACCEPT.
sudo iptables -A PREROUTING -t nat -i ens33 -p tcp --dport 22 -j DNAT --to <IP_ADDRESS>:54045
sudo iptables -A FORWARD -p tcp -d <IP_ADDRESS> --dport 54045 -j ACCEPT
Result: SSH operation timed out. Also tired INPUT and FORWARD policy ACCEPT still operation timed out.
2nd Attempt
INPUT and FORWARD policy DROP, OUTPUT policy ACCEPT.
sudo iptables -A FORWARD -i ens33 -o ens37 -p tcp --syn --dport 22 -m conntrack --ctstate NEW -j ACCEPT
sudo iptables -A FORWARD -i ens33 -o ens37 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
sudo iptables -A FORWARD -i ens37 -o ens33 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
sudo iptables -t nat -A PREROUTING -i ens33 -p tcp --dport 54045 -j DNAT --to-destination <IP_ADDRESS>
sudo iptables -t nat -A POSTROUTING -o ens37 -p tcp -d <IP_ADDRESS> -j SNAT --to-source <IP_ADDRESS>
Result: SSH operation timed out. Also tired INPUT and FORWARD policy ACCEPT connection refused.
3rd Attempt
INPUT, FORWARD and OUTPUT policy ACCEPT.
sudo iptables -t nat -A PREROUTING -p tcp --dport 22 -j DNAT --to-destination <IP_ADDRESS>:54045
sudo iptables -t nat -A POSTROUTING -j MASQUERADE
Result: This did work but only when the chain FORWARD had its policy on ACCEPT. This is the only time I got a connection through the firewall. When I changed the chain FORWARD to DROP the SSH connection would time out again.
My guess it is something to with it being masqueraded or that FORWARD policy DROP has something to do with it.
My question is what am I overlooking? It’s probably something I’ve missed all this time that is staring me in the face. Please be kind and thank you for your help.

When outdoors, I am able to get the coordinates of the users position almost instantly and the app works great. Indoors, as expected, does not have GPS signal so I cannot get the location. That said, iOS uses Wifi and various other techniques to show my approximate location on a MapView still. However, I am unable to get the approximate coordinate while indoors even though iOS knows it (ie. didUpdateLocations is never called while indoors but is the second I walk out the door).

I do see some bugs related to this issue - https://github.com/reactiveui/refit/issues/689. It is claimed to have been fixed in the .net core 3.1 version. But I haven't been able to retrieve the response header yet.

public interface IService
{
[Post("/v1/Authtoken/")]
public Task<string> Authenticate([Body] Authenticate payload);
}

In the view model, I got the authtoken value with the following statement.

It's a pity that the client has to be bound to an activity, because one cannot go through different activities with the same client, but that's the way it is. It's also a pity that there is no feedback one could rely on to debug this.

Es decir, se abre y se cierra la ventana del gráfico en un instantte. ¿Eso puede ser problema del paquete gnuplot que tengo instalado? |

/errors.php will refer to your base url, e.g. http://localhost/errors.php. If you are working with a project directory (e.g. http://localhost/project_dir/), the path to the errors.php-file should be /project_dir/errors.php.
With this change, the code works fine on my system.

First try to display the data with PHP, make it more complex when you're sure the connection between jQuery and PHP is working well.
Use Firebug or developer tools to see if there errors occur.

Check if there is the creation of .git file after doing git init.
Check the branch using git branch and a look if you are at
the master branch.
Then check the status of the files using git status it will show if any file is changed.
Then do git add individual file or git add . as you wish.
Then commit the changes.
And then push.
If git add . fails there is a possibility that the next steps will also fail.And also check git remote -v if your origin branch is at the remote.

else if(input == 2) {

}
Also if you want the program to keep prompting you can just wrap it in a loop. Here is a small example using a boolean sentinel to keep the loop going. This is one of many ways to implement this task.
public static void main(String[] args) {
System.out.println("Please enter 1 to add or 2 to multiply. "); // ask user to input 1 or 2
Scanner in = new Scanner(System.in);
boolean inputNotValid = true;
while(inputNotValid){
int input = in.nextInt();
if(input == 1) {
inputNotValid = false;
//add
System.out.println("adding");
}
else if(input == 2) {
inputNotValid = false;
//multiply
System.out.println("multiplying");
}
else {
System.out.println("Operation failed. You need to enter 1 or 2. Try again");
}
}

For example, if we have the word javascript, then the output should display jav-------, pebbles should display as peb----, or instead of python, the output should display pyt---, etc.
Would str.replace(old, new) or str.replace(old, new, count) work in this case? If yes, then how?
Here is an example I did:
>>> p = "kotlin"
>>> p = p.replace(p[3:], "-")
>>> p
'kot-'
>>>
The desired output would display kot---, however, although it does show the first 3 letters in the word, kot- only shows one dash in the end.
What could be another way to approach this?

We say that an ordering $\preceq$ is Pareto if it obeys the following rule: If there is some index $i$ such that $x_i\leq y_i$, and for all other $j\not = i$, $x_j = y_j$, then $x\preceq y$.
I was wondering if any Pareto ordering's are computable in this set that I mentioned. I suspect the answer is no, but someone told me proof which I don't understand:
One confusion I have is that this seems to prove that the rational numbers themselves cannot be computably ordered, a contradiction.
What am I misunderstanding?
| 4301589054fbd7d10a343adbc7f23f49f467ccc9feac6438910457fc42c68749 | ['6c3e95662f1744098ee9ba439f0de69c'] | As you allude to in your question, it might be more useful to consider the equivalence classes of your set, rather than the set itself. $S/f$ has a lot of nice properties: it's totally ordered, etc.
By the way, you tagged this as lattice-orders; if this was intentional, you can prove the following little theorem:
Theorem: if $S_i$ has more than one element, then $S_{i +1}$ must have only one element.
To see this, just note that $S_i$ must have not just an upper bound, but a least upper bound.

Just what you need to improve and finalize your plugin is that in newer WordPress versions, there are two different tables that contain user data. They are wp_user and wp_usermeta. And in the plugin, it is provided only one table to authenticate. So if this feature goes right, definitely your plugin is 100% successful.
What else, is that there is a bug. As there is only one table to authenticate, so I couldn't authenticate user roles and sync them. This means when I enable external login, the time I logged out, and login the next time, I am of subscriber role, that I have specified if no roles matches. So i loosed my adminship too. Kindly help and understand.

Previously we did it with Veeam because we were using a Windows Server, but now with their Hypervisor we couldn't find some way to do it.
What I've already seen:
Veeam - Couldn't find an apropriate solution for what we need, is it possible to install it or use remotely without paid agent solutions?
OVF Export - From what I did understand by reading this feature would use the network to export the VM. That´s not exactly what I'm looking for (if it's this)
ghettoVCB.sh - I'm not sure if this one works with this version, from what I did read it works with version 5 and 4.
Is there any other way to achieve this using free alternatives to communicate with ESXi 6.7?
Thank you very much!

I had already created a WCF Client (Service Reference) that worked, and by looking closely at the generated code, I figured out what is happening. It has to do with way WCF wrappes all classes used in the DECLARATION of Webservice methods (so the classes used in properties of the method-mentioned-classes are not wrapped). In my case, the body of the ZAKLk01 class get wrapped with XMLElement tags, using the parametername as XMLElement-name. To get rid of this behaviour I am now using wrapper classes for my generated proxy-classes ZAKLk01 and Bv03Bericht, just like the generated classes do of my Service References proxy classes in my new WCF Client. These wrapper classes are decorated with MessageContractAttributes.
To give an example of one of those wrapper classes:
[MessageContract(IsWrapped = false)]
public partial class zakLk01Request
{
[MessageBodyMember(Namespace = Constants.NamespaceStufZKN, Order = 0)]
public ZAKLk01 zakLk01;
public zakLk01Request()
{
}
public zakLk01Request(ZAKLk01 zakLk01)
{
this.zakLk01 = zakLk01;
}
}
My Interface method now looks like this:
[OperationContract(Action = Constants.NamespaceStufZKN + "/zakLk01", ReplyAction = Constants.NamespaceStufZKN + "/Bv03Bericht")]
[FaultContract(typeof(Fo03Bericht), Namespace = Constants.NamespaceStuf)]
zakLk01Response zakLk01(zakLk01Request zakLk01);
Much cleaner without the XMLElement tags, which function (generate correct xml) have now been replaced by the wrapper classes.
The reason I could receive non-wrapped xml, was that my custom messageinspector contained some code, meant to accept non-wrapped xml messages without having to add MessageContract tags to all existing classes (or create lots of wrapper classes) (googled it somewhere), which it did just fine. Code snippet:
MessageDescription.Body.WrapperName = null;
But receiving wrapped messages which were send by my (first) WCF Client which still wrapped the classes didn't work, off course...
What I still don't understand is how those Action attributes work: if I don't supply them, my generated wsdl does not contain any method. Well, not important for now, since I can finally move on, and will tinker with the Action attributes some other time.

If it possible for you, you should use other control instead of the Combobox to handle a big data.
I assume that your users should know which madicine they want to select, so they could put a part of medicine name in search box. This just a choice, you may use TextBox (names txtMedicines in my sample code) with AutoComplete to search binding data when user enter some word to search in the list.
This is a sample code
private void InitializeMedicinesAutoComplete()
{
var searchMed = Lookup.Medicines
.Where(d => d.DosageForm.Equals(cmbType.SelectedValue.ToString())).ToList();
var source = new AutoCompleteStringCollection();
foreach (var med in searchMed)
{
// **DisplayMemberText mean any field that you want to display in searching list
source.Add(med.DisplayMemberText);
}
txtMedicines.AutoCompleteMode = AutoCompleteMode.Suggest;
txtMedicines.AutoCompleteSource = AutoCompleteSource.CustomSource;
txtMedicines.AutoCompleteCustomSource = source;
}
private void cmbType_SelectedIndexChanged(object sender, EventArgs e)
{
InitializeMedicinesAutoComplete();
}
I hope this will help.

I have successfully done the opposite (from char to wchar_t*) with mbsrtowcs(), but this defeats me. The return value section inman 3 wcsrtombs has this:
The wcsrtombs() function returns the number of bytes that make up the
converted part of multibyte sequence, not including the terminating
null byte. If a wide character was encountered which could not be
converted, (size_t) -1 is returned, and errno set to EILSEQ.
Consider this minimal example:
#include <string.h>
#include <time.h>
#include <stdlib.h>
#include <ctype.h>
#include <stdbool.h>
#include <locale.h>
#include <wctype.h>
#include <wchar.h>

size_t buffer_size = num_chars * sizeof(wchar_t);
char *mb = malloc(buffer_size); // will waste some memory though
mbstate_t state;
wcsrtombs(NULL, &arg, 0, &state); // this supposedly will initialize the mbstate_t struct
size_t result;
result = wcsrtombs(mb, &arg, buffer_size, &state);
if (result == (size_t)-1) {
free(mb);
return NULL;
}
mb[buffer_size-1] = '\0';
return mb;
}
int main(int argc, char* argv[]) {
setlocale(LC_ALL, "fi_FI.UTF-8");
wchar_t test[] = L"ÄÄÄÄÖÖÖÖ";
char *converted = convert_to_multibyte(test, wcslen(test));
// printf("%s\n", converted);
return 0;
}
With the test string L"ÄÄÄÄÖÖÖÖ", (size_t) -1 is returned, which implies an inconvertible wide char was encountered - this doesn't happen with a string that doesn't have any non-ASCII characters. What am I not understanding here?

Please excuse me for the maybe basic question but I'm trying to obtain some more common knowledge on the matter. This is why I'd very much like detailed explenations and tips/tricks for future designs.

What you could do is create and additional field for your "ID" field that you want to duplicate and then you can insert normally and leave the auto incrementing field do it's thing.

Every page displays 60 players and so I use offset query param(for example https://sofifa.com/players?offset=60 shows 2nd page) to access all player's info.
One thing I noticed is that the offset value never ends(i.e. no matter how large the offset value I provide, it always shows me a page). Specifically, I noticed that for offset > 20000 or so, it always displays the 1st page(essentially after exhausting all players, it kinda rolls over to the 1st page and always displays that for all subsequent higher offset values). Try with https://sofifa.com/players?offset=20000000 to get an idea of what I mean.
I want to know if there is any way I can programmatically find out the last "valid" offset value; beyond which I am sure to get the 1st page back. That'll help me decide when I reached the end of the dataset.
Currently this is how I scrape:
for offset in range(0, 20000, 60):
try:
print("Processing page at offset " + str(offset))
sofifa_url = "https://sofifa.com/players?offset=" + str(offset)
# start scraping the page

To aggregate points given by wine reviewers, I noticed that, when I used mean as a standalone function in agg():
reviewer_mean_ratings = reviews.groupby('taster_name').points.agg('mean')
The output looks like this:
Noticed that the output has 2 columns(at least that's what it looks like visually). But
type(reviewer_mean_ratings) = pandas.core.series.Series
Is that just 1 column with space between the name and mean rating? I'm confused.
Also noticed that, I cannot sort this output in descending order by the mean ratings. Instead if I had used mean as a list in agg() then descending order works using sort_values() method later.
My hypothesis is that if I want to access the mean ratings column later, the only way to do it is to use agg(['mean']) instead of agg('mean') in the original query. Am I mistaken somewhere?

Given the scale and complexity of your project I must advise against blindly changing the TargetFramework property and hoping for the best.
While 4.0 executables can load 2.0 DLLs, it is not recommended because of the breaking-changes I described.
You will run into problems with the mixing of C++ code. I recommend you start by upgrading (or rather, rewriting) your "Managed Extensions for C++" code to C++/CLI (you might want to take advantage of C++11 and C++14 features present in VS2015 while you're at it).
I recommend upgrading each project individually and separately, working your way up the dependency-chain. It will help if you have (or will write) unit tests and integration tests for more critical parts of your system.

It seems to be building a SQL statement by string concatenation without performing any sanitation. This might be acceptable if all input can be trusted, but given it's a public function I don't think that's the case.
The return true seems superfluous as it never returns anything else - the author might have intended it as a way to ensure the function completed, which implies the code it uses fails-silently instead of calling die() or throwing an exception.
Style-wise, the author isn't consistent with concatenation: in some places it's straight-forward concatenation with the . operator, in other places it uses $placeholders.
If $changes is empty then the call to substr will fail, doing a trim after building a list is the wrong way to comma-separate list-items. This is how I'd do it (except, never with SQL, of course):
$first = true;
foreach($changes as $field => $value ) {
if( !$first ) $update .= ", ";
$first = false;
$update .= "`$field` = '{$value}'"; // NEVER DO THIS
}
Thinking about it - the only thing good about this function is it's well-documented.

I'd like to have an option to shoot with multiple light sources - at least 4. My other priorities are low cost and also correctness of color rendering.
I'm puzzled whether should I choose LED lighting or flashes for that purpose. What considerations should I take into account?
Here are pros and cons of each option that I see.
LED
Pros
Relatively cheap (though there are cheap flashes too, so it's possible to buy cheap slave-flashes for additional light sources).
Ability to model lighting before shooting.
Cons
Poorer color rendering compared to flashes.
Flash
Pros
Much more usable outdoors:
Flashes can suppress unneeded light by overpowering it.
Ability to shoot at very high shutter speeds to avoid blurry images or capture moving subjects.
Better battery life.
Best color rendition.
More lightweight than LEDs.
TTL.
Cons
More complex/costly setup for multiple flashes with wireless communication.
Hard to choose right one - there are so many different flash manufacturers with incompatible wireless communication protocols.

In this way anyone administering the machine could destroy it with an unintended command. This is why you should always create one or more less privileged (read: ordinary) users.
If needed these less privileged users could use the "sudo" command in order to execute tasks requiring root privileges.

There should be HasMany<> relationships in each of those mapping classes, but I got lazy. If you go the route of including a .hbm.xml file, I'd recommend using the .ExportTo("c:\") function when you configure your ISessionFactory and you can just edit the hbm file that fluent puts out. It's a great starting point.

When testing an installer for our C# (.NET 4.0) software recently, we installed on 7 or 8 different machines with success. But, one of our QA members installed and was able to get the application to consistently crash on his machine.
The first thing our application does - before anything else - is to spawn an external application, wait for it to do its thing, (more on this later) then exit. If we didn't launch the external application, it would prevent the crash on his machine.
The truly odd thing is that the crash happens much later in the main application. Long after the external exe had finished and exited. To verify that it wasn't the external process itself, I had the main app launch notepad instead. When he exited notepad, the application would resume as usual. This ALSO caused the crash. In the end, telling the external application to start up with "Process.UseShellExecute = false" prevented the crash.
//Successful code
Process myProcess = new Process();
myProcess.StartInfo.FileName = "MyProcess.exe";
myProcess.StartInfo.UseShellExecute = false;//Only difference between crashing and non-crashing code
myProcess.Start();
myProcess.WaitForExit();
...
myProcess.Dispose();
myProcess = null;
Other relevant info:
The crash always happened on an attempted method call in an imported DLL written in Delphi 5 ages ago. Unfortunately, I don't know much about the inner-workings of this DLL, but the fact that this has only failed on this specific machine makes me think that it's not the issue.
The error we got from event viewer was this:
Faulting module name: ntdll.dll, version: 6.1.7601.22436, time stamp:
0x521eaa80 Exception code: 0xc0000374
(0xc0000374 is a heap corruption)
It makes sense to me that the two types of execution would be different, but what could be different about this person's machine that using the Windows Shell would cause a crash?

So unless the file name itself is saying something like "libXXX.VERSION.so", there is no other way to find out the version number of the shared object. This technique is generally used in Linux.
My suggestions for solving your issue are:
Use Date modified if possible to differentiate the shared objects
Use dlopen() or similar to open the shared object and try to see the functions being exported.

Create my own logger class based on log4j
Override activateOptions() to save off the files before logging starts
Leave everything else the same.
But that raises some questions:
Is activateOptions() the correct place for this logic?
Is there an equivalent of activateOptions() in basic Java logging or must I go with log4j?
Is there a better way that I've not yet discovered?
Thanks for any suggestions.

The R FAQ recommends a different approach for speed
7.10 How do I convert factors to numeric?
It may happen that when reading numeric data into R (usually, when reading in a file), they come in as factors. If f is such a factor object, you can use
as.numeric(as.character(f))
to get the numbers back. More efficient, but harder to remember, is
as.numeric(levels(f))[as.integer(f)]
In any case, do not call as.numeric() or their likes directly for the task at hand (as as.numeric() or unclass() give the internal codes).

So what is the signature?
In computing, a file signature is data used to identify or verify the
contents of a file. In particular, it may refer to:
File magic number: bytes within a file used to identify the
format of the file; generally a short sequence of bytes (most are
2-4 bytes long) placed at the beginning of the file; see list of file
signatures
File checksum or more generally the result of a hash function over the file contents: data used to verify the integrity of the file
contents, generally against transmission errors or malicious attacks.
The signature can be included at the end of the file or in a separate
file.
I used the magic number to define the magic number term I'm copying this from Wikipedia
In computer programming, the term magic number has multiple
meanings. It could refer to one or more of the following:
Unique values with unexplained meaning or multiple occurrences which could (preferably) be replaced with named constants
A constant numerical or text value used to identify a file format or protocol; for files, see List of file
signatures
Distinctive unique values that are unlikely to be mistaken for other meanings(e.g., Globally Unique Identifiers)
in the second point it is a certain sequence of bytes like
PNG (89 50 4E 47 0D 0A 1A 0A)
or
BMP (42 4D)
So how to know the magic number of each file?
in this article "Investigating File Signatures Using PowerShell" we find the writer created a wonderful power shell function to get the magic number also he mentioned a tool and I'm copying this from his article
PowerShell V5 brings in Format-Hex, which can provide an alternative
approach to reading the file and displaying the hex and ASCII value to
determine the magic number.
form Format-Hex help I'm copying this description
The Format-Hex cmdlet displays a file or other input as hexadecimal
values. To determine the offset of a character from the output, add
the number at the leftmost of the row to the number at the top of the
column for that character.
This cmdlet can help you determine the file type of a corrupted file
or a file which may not have a file name extension. Run this cmdlet,
and then inspect the results for file information.
this tool is very good also to get the magic number of a file. Here is an example
another tool is online hex editor but to be onset I didn't understand how to use it.
now we got the magic number but how to know what type of data or is that file or stream?
and that is the most good question.
Luckily there are many database for these magic numbers. let me list some
File Signatures
FILE SIGNATURES TABLE
List of file signatures
for example the first database has a search capability. just enter the magic number with no spaces and search
after you may find. Yes, may. There is a big possibility that you won't directly find the file type in question.
I faced this and solved it by testing the streams against specific types of signatures. Like PNG I was searching for in a stream
def GetPngStartingOffset(arr):
#targted magic Number for png (89 50 4E 47 0D 0A 1A 0A)
markerFound = False
startingOffset = 0
previousValue = 0
arraylength = range(0, len(arr) -1)
for i in arraylength:
currentValue = arr[i]
if (currentValue == 137): # 0x89
markerFound = True
startingOffset = i
previousValue = currentValue
continue
if currentValue == 80: # 0x50
if (markerFound and (previousValue == 137)):
previousValue = currentValue
continue
markerFound = False
elif currentValue == 78: # 0x4E
if (markerFound and (previousValue == 80)):
previousValue = currentValue
continue
markerFound = False
elif currentValue == 71: # 0x47
if (markerFound and (previousValue == 78)):
previousValue = currentValue
continue
markerFound = False
elif currentValue == 13: # 0x0D
if (markerFound and (previousValue == 71)):
previousValue = currentValue
continue
markerFound = False
elif currentValue == 10: # 0x0A
if (markerFound and (previousValue == 26)):
return startingOffset
if (markerFound and (previousValue == 13)):
previousValue = currentValue
continue
markerFound = False
elif currentValue == 26: # 0x1A
if (markerFound and (previousValue == 10)):
previousValue = currentValue
continue
markerFound = False
return 0
Once this function found the magic number
I split the stream and save the png file
arr = stream.read()
a = list(arr)
B = a[GetPngStartingOffset(a):len(a)]
bytesString = bytes(B)
image = Image.open(io.BytesIO(bytesString))
image.show()
At the end this is not an end to end solution but it is a way to figure out streams content

for E. coli I use D554.87 = 19.35 min; for Salmonella I use D557.58 =
13.18 min; and for Listeria I use D559.22 = 12.66 min. For my calculations I used a thermal diffusivity of 1.11×10-7 m2/s, a surface
heat transfer coefficient of 95 W/m2-K, and took β=0 up to 30 mm and
β=0.28 above 30 mm (to simulate the heating speed of a 2:3:5 box). For
more information on calculating log reductions, see Appendix A. [Note
that if the beef is seasoned using a sauce or marinate which will
acidify the beef, then the pasteurizing times may need to be doubled
to accommodate the increased thermal tolerance of Listeria (<PERSON> and
<PERSON>, 1996).]
There is more of this information available. Look for sous vide cooking times to see the appropriate cooking time for you choice of protein.

For delegates that point to void functions such as in your case, you can use Action.
Instead of declaring and instantiating a delegate (or in this case an Action delegate) you can stick it directly in your SetWinEventHook method like this.
The compiler will take care of instantiation.
public void SetWinEventHook(Action<IntPtr, uint, IntPtr, int, int, uint, uint> myDelegate)
{
}
Now in order to kick off the function that your delegate points to you do this
myDelegate()
the problem, however, is that this delegate needs the 7 arguments that you declared it will need.
In order to provide that you can pass them in as a second argument in your SetWinEventHook method like this
public void SetWinEventHook(Action<IntPtr, uint, IntPtr, int, int, uint, uint> myDelegate, IntPtr a, uint b, IntPtr c, int d, int e, uint f, uint g)
{
myDelegate(a,b,c,d,e,f,g);
}
So at this point you essentially
1) Declared a delegate
2) Instantiated a delegate
3) Created a hook method to kick off the delegate/function
Now all you need to do is call your SetWinEventHook and pass in either a lambda or a function written elsewhere so that your delegate will point to it.
SetWinEventHook((a, b, c, d, r, f, g) => // using lambda here
{
},
new IntPtr(), 1, new IntPtr(), 2,3,4,5
);

We can see this easily if we're working with factorials. For the combinatorial proof the left hand side is simply choosing $k$ objects from $n$ objects.
We can do the same on the rhs by first fixing one of the $n$ objects and then picking the rest of the $k-1$ objects from the remaining $n-1$ objects. This gives us $\binom{n-1}{k-1}$ $ { }$ $k$-selections containing our fixed object. Since there are $n$ objects we get a total of $n\binom {n-1}{k-1}$ $ { }$ $k$-selections.
However we can see that each $k$-selection will be repeated $k$ times. This is because fixing each element of a $k$-selection introduces this $k$-selection. Dividing by $k$ gives us $$\binom{n}{k} = \frac{n}{k}\binom{n-1}{k-1}$$
We can now simplify your expression to give:
\begin{align*}\sum_{k=1}^n k \binom{n}{k}^2 &= \sum_{k=1}^n k \binom{n}{k}\binom{n}{n-k} \\ &= \sum_{k=1}^n n \binom{n-1}{k-1}\binom{n}{n-k} \end{align*}
By disregarding the common factor $n$ we simply have to prove that
$$ \sum_{k=1}^n \binom{n-1}{k-1}\binom{n}{n-k} = \binom{2n-1}{n-1} $$
It is easy to see that we can also select $n-1$ objects from $2n-1$ objects by first choosing $k-1$ objects from a fixed $n-1$ objects then by choosing $n-k$ objects from the remaining $n $ objects. See <PERSON>–Vandermonde identity .

Think of it by building a tree:
iterate along the string
if the character is '1', add a node to the the root of the tree.
if the character is '2', add a child to each first level node.
if the character is '3', add a child to each second level node.
return the number of third layer nodes.
this would be space inefficient so why don't we just store the number of nodes a each depth:
infile >> in;

switch(in[i]) {

you can find the solution to your problem in this link here
plus I 've made a stackblitz example for you to simplify it more.
Example
to describe the solution:
you have to add to your autocomplete component an input called displayWith
<mat-autocomplete #auto="matAutocomplete" [displayWith]="checkValue">
and then in your component you have to create the function checkValue
checkValue(value: any) {
// here you can get your id or whatever you want
console.log(value)
}
then you have to add to your mat option the value and give it your whole object as value
<mat-option *ngFor="let option of options" [value]="option" >
{{option.name}}
</mat-option>

Are you sure you are sharing the $scope of your controller with the dialog?
If the div creating your dialog is not accessible by your controller, which means it's not a DOM node in the subtree of children of your controller root element, it will not display the properties (and will give no errors)
Where are you calling $scope.errorDialog?
If you are running that call outside of a $digest loop, you can maybe solve this by calling $scope.$apply after setting the properties. This wouldn't be the best solution though, it would be better to wrap the call of this function in the following fashion
$scope.$apply(function() {
$scope.errorDialog('title', 'message');
})
This would allow AngularJS to eventually intercept errors happened while executing $scope.errorDialog

There are two lists, A and B, and I want to rearrange B so that it is in the same relative order as A - the maximum element of B is in the same position as the current position of the maximum element of A, and the same for the minimum element, and so on.
Note that A is not sorted, nor do I want it to be.
As an example, if the following were input:
a = [7, 14, 0, 9, 19, 9]
b = [45, 42, 0, 1, -1, 0]
I want the output to be [0, 42, -1, 0, 45, 1].
Please note that the intended output is not [0, 45, 1, 0, 42, -1], which is what it would be it you zipped the two and sorted by A and took the resulting elements of B (this is what all of the other questions I looked at wanted).
Here's my code:
def get_swaps(x):
out = []
if len(x) <= 1:
return out
y = x[:]
n = -1
while len(y) != 1:
pos = y.index(max(y))
y[pos] = y[-1]
y.pop()
out.append((pos, n))
n -= 1
return out
def apply_swaps_in_reverse(x, swaps):
out = x[:]
for swap in swaps[<IP_ADDRESS>-1]:
orig, new = swap
out[orig], out[new] = out[new], out[orig]
return out
def reorder(a, b):
return apply_swaps_in_reverse(sorted(b), get_swaps(a))
The approach is basically to construct a list of the swaps necessary to sort A via selection sort, sort B, and then apply those swaps in reverse. This works, but is pretty slow (and is fairly confusing, as well). Is there a better approach to this?

In my particular case, it happened to be 16bit registers, but that's not overly important, and for the purposes of example, I'm going to pretend that they were only 4bit.
Basically, their behavior is this:
mov r0, #0x1011
lsl r0, #0x1
The mov would set r0 to 1000, and then the lsl would shift them, but because the number inside r0 is already 4bits, and, as I said earlier we're pretending we're working with 4bit registers, that bit is lost, and r0 would become #0x0110.
Basically what happens is, to lsl something by n bits, the n most significant bits are lost, the rest of the value is shifted as expected, and 0s are added to fill in the least significant bits.
This probably has a name, sorry, I don't know what it is, but hopefully what I'm referring to is clear enough.
I'm working with the << operator in Python, and I need this to happen. Practically, I need to split up a 16bit number into it's most significant 3 bits, next most significant 2 bits, etc.
Is there a simple way to handle this that's already built into Python? I know a way to do it, but rather than bothering with that, I figured it'd be worth asking if such a feature was built in.
Thanks.

{ 2,2,2} , {2,4} , {4,2} , {6}
What I've tried:-
I'm trying to approach this problem using the popular "coin change" question. But in coin change permutations are not there. Means {2,4} and {4,2} are regarded as same. Here's my code. It doesn't account permutations.
public static int NumberOfWays(int sum)
{
int [][] memMatrix = new int [7][sum+1];
for (int i = 2 ; i <= 6 ; i += 2)
{
for (int j = 0 ; j <= sum ; j += 2)
{
if (i == 2)
{
//using only 2 , there is only 1 way to get the sum
memMatrix[i][j] = 1;
}
else if ( i > j)
{
//if total sum is less than the newly used denomination , then the number of ways will always remain same
memMatrix[i][j] = memMatrix[i - 2][j];
}
else
{
//if this is the case then need to calculate without using the denomination + using the denomination
memMatrix[i][j] = memMatrix[i - 2][j] + memMatrix[i][j - i];
}
}
}
for (int i = 2 ; i <= 6 ; i += 2)
{
for (int j = 2 ; j <= sum ; j += 2)
{
System.out.print(memMatrix[i][j]+" ");
}
System.out.print("\n");
}
return memMatrix[6][sum];
}
Here's the output that I get along with the matrix. How can I account permutations also?
1 1 1
1 2 2
1 2 3
The number of ways to get 6 = 3

Now I'm migrating some code to the client side to dynamically update a table once a new item is created; the table has action links that point to other endpoints. Is there something like ctx.Link on the client side I can use?
I'd rather avoid creating the link by myself (e.g. with sprintf) because I want the EndPoint type to be authorative for everything URL related.

With a JavaScript function to return to the top of the page when the navbar is clicked as follows:
$('.back-to-top').click(function () {
$('html, body').animate({ scrollTop: 0 }, 'slow');
return false;
});
However, I still want to be able to follow the links within the navbar but they are being overridden by the JS function so when you click on them now it scrolls to the top.
How do I make it so the links within the navbar are still useable but the 'back-to-top' function works when you click on the rest of the navbar, thanks.

.field_with_errors .form-control {
&:extend(.has-error .form-control);
}
.field_with_errors .form-control:focus {
&:extend(.has-error .form-control:focus);
}
When I tried it with:
.field_with_errors {
&:extend(.has-error);
}
which is the equivalent of the recommended way I found to use the bootstrap 3 style for errors, LESS wasn't doing anything. It may have something to do with the fact that the selectors in bootstrap 3 that mention has-error always have it combined with something else, e.g.:
.has-error .form-control {
Anyway - the above solution worked for me so hopefully it helps someone else.

I've noticed lately that the simulator will sometimes cause all HTTP requests to error out with that for no reason and only restarting it clears the issue.
Also, I have found that some HTTP errors can end up with a nil localizedDescription on the error object. What are you seeing on the NSLog line where you print that out?

Using a CA code signing cert (example: DigiCert.com) will maintain the signed files valid for life when adding "timestamp" to sign the jar file(s). Any OS or browser will automatically trust the source (your organization) because a valid CA issued it (DigiCert). The pre-loaded root certs link to the code signing cert even after the code signing order expired. CA's will update their Root Certs a few years before it expires.

Replacing the cert on Apache is very simple. Just go to your httpd config file and point to the new Private key, Domain Cert, and Intermediate Cert. Restart the service and finish!

If your code uses finalizers, you may wish to look into GC.KeepAlive(). In the following block:
void MyFunction()
{
Foo f = new Foo();
SomeFunction(f.SomeProp);
}
f becomes eligible for finalization before SomeFunction() even runs! If the finalizer does something like dispose whatever SomeProp hands out, you could get into trouble. Adding a call to GC.KeepAlive(f) after the call to SomeFunction ensures that f isn't eligible for finalization until after the call to KeepAlive().
Edit: After all that, I forgot to point out that this problem was much more pronounced when running in Release mode. I don't know if the Debug build puts implicit KeepAlives for locals at the end of the function for the debugger's benefit, or if the garbage collection is simply less aggressive, or what, but Release mode exacerbated this problem greatly in my case.
