Is there anyway I can start the new logstash consumer group with the initial offset from last consumer group?
Thanks

i have searched but couldn't find anything about it. and i skirmed through "gsutil rsync" code and came to the conclusion that it is copying the entire file even if there is a small change in the file(please correct me if it is not the case.)
ps: if there are no such methods i will try to save 256KB blocks of each file. (my file sizes are in the range of 1MB-50MB)
pps: actually i want to upload only the delta of some binary files that i'm storing from android app. if you know any known tool or workflow for this please do answer.

So $p= \frac{1}{m}\cdot\frac{1-(1-\frac{1}{m})^n}{1-(1-\frac{1}{m})}
=1-(1-\frac{1}{m})^n$.
This gives a hint for a simpler method, as suggested by @MichaelHardy:
The probability to have no side A in one toss is $(1 - \frac{1}{m})$, for $n$ tosses it's $(1 - \frac{1}{m})^n$.
The probability to have at least one side A in $n$ tosses is the complement $1-(1 - \frac{1}{m})^n$. Both methods work. | 91cbc234e2eb90c15e93a80c931cd8d8e627dcb66b81357405c86c9b425469b5 | ['4af24e0d0b314867932f446932efee37'] | You have a few issues:
users migration:

Change it to this: $table->string('username')->unique(); - this will add a column and unique index for it.
encomenda migration:
$table->string('username')->unsigned();: unsigned is used only with integers, you can't make a string unsigned.

A a = new A();
where "a" is the name of the object. Then you can access the getter method by calling a.getIntI. You can also declare the int variable as static so that you wouldn't have to instantiate any objects. An example of class A with the static variable and getter method would be:
public class A {
private static int i = 1;
public static int getIntI() {
return i;
}
}
With this, you can call the getter method with A.getIntI().

How do I model this? Should I define a new method like all_reviews in my model that fetches and merges the reviews or is there any straight forward way through associations?

I apply a custom scrollbar to the control in the generator code, but it doesn't get applied as the element has not been appended to the DOM yet.
My question: Is there any onAppend event or something like that, so that I apply the custom scrollbar at the time when the element has been appended to the DOM?
Sample code for generator:
function getControl(controlParams){
var $control = $('<div/>');
$control.applyCustomScrollBar(); //Not appended to DOM yet, so doesnt work
return $control;
}
Sample code for consumer:
var $control = getControl(controlParams);
$("body").append($control); //Appending to DOM now
Want to do something like:
function getControl(controlParams){
var $control = $('<div/>');
$control.onAppend(function(){
$(this).applyCustomScrollBar();
});
return $control;
}

Right now instead of adding up all the numbers I typed in before typing 0, it just takes the last typed in number... The number count does go up however, which is why I'm pretty confused.
For example:
Enter number: 2
Enter number: 6
Enter number: 4
Enter number: 7
Enter number: 0
There are 4 positive numbers (Works like I intended)
The total amount is 7 (Is supposed to be 2+6+4+7 = 21)
Console.Write("Enter number: ");
string numberInput = Console.ReadLine();
double number = double.Parse(numberInput);
int count = 0;
double begin = 0;
double total = 0;
while (number != 0)
{
if (number >= 0)
{
count++;
total = begin + number;
}

Here is what you intended to do,
inp= int(input())
list1 = []
while inp != 0:
list1.append(inp)
inp = int(input())
def isPalindrome(N):
str1 = "" + str(N)
len1 = len(str1)
for i in range(int(len1 / 2)):
if (str1[i] != str1[len1 - 1 - i]):
return False
return True
list2 = []
for i in list1:
if isPalindrome(i):
list2.append(i)
print(list2)
Also if you want to make your program much shorter than i recommend this,
def isPalindrome(N):
str1 = str(N)
if str1[<IP_ADDRESS>-1] == str1:
return True
else:
return False
Just a slight change in synatx but logic is though same as yours. It uses string slicing in reverse direction.
Also i have type casted the input to integers using int(input()) as you said you need numbers to be printed in list2, if you don't want integers then just replace all int(input()) with input() and change your if condition to int(inp)!=0 at beginning

Besides the need of more data before feeding the model, I also need to crop some of the images using OpenCV, so this pre-processing step would contain both the enlargement of the dataset and the cropping of the images when needed!

<EMAIL_ADDRESS>,
<EMAIL_ADDRESS> and
<EMAIL_ADDRESS>
are automatically delivered just like mails to <EMAIL_ADDRESS>. There is no need to register or set up these 'plus suffixes'. The user can just use them and set up client-side filtering rules on his own.
Does Exchange support a similar mechanism? If so, how to enable it?
Note that I don't want answers about other means of filtering, e.g. spam/junk filtering, server-side or client-side rules, email aliases/addresses that are configured explicitly and so on.

The Cycle Plugin executes this well in FireFox, but in Safari and Chrome, upon initially loading the page, I do not observe the "slideshow" and only see a single image.

It turned out that the problem was not with JQuery, the Cycle Plugin, or the Webkit browsers, but with the images. The source PSD that I used to create the gifs held the Photoshop layers in an animation timeline and that data was being included when I was using "Save for Web & Devices" in Photoshop- interesting that it did not pose a problem in Firefox. The solution was to simply "Delete Animation" in the Animation palette and save the gifs once more.
Thanks to all who pondered this one.

insert into report_question (reportid, questionid) values (3, 3);
Initial query looks like
select r.*, rc.*, cattype.*, rq.*, question.* from report r
left join report_cattype as rc on (r.reportid = rc.reportid)
left join cattype on (rc.cattypeid = cattype.cattypeid)
left join report_question as rq on (r.reportid = rq.reportid)
left join question on (rq.questionid = question.questionid)
Now I'm thinking I'm better off running multiple queries and combining them together in my application - Query all reports, then query table report_question or report_cattype for each report. Thoughts?

From: http://spark.apache.org/docs/latest/configuration.html :
spark.executor.heartbeatInterval 10s Interval between each executor's heartbeats to the driver. Heartbeats let the driver know that the executor is still alive and update it with metrics for in-progress tasks.

A big table which will only be used for "select" and a smaller table which will be used mainly for "insert" and sometimes also "select". Each time period (I thought about a day) I will merge the smaller table into the big one.
Regrading the big table: is there a way I can improve performance by telling the mysql server it's read-only? Considering it's only for select, can I assume it will handle SELECT in less than 1sec. when it will become ~1e9 rows?
Regarding the small table: any tuning I should do here? what is the best way to develop an automated merge process from the small to the big table (in php)?

When checking the process status list, I am noticing that when this happens there are very long processes which are in sleep state. How long? time:28490
This is how I init the connection:
$this->connection[$server] = mysql_connect( $credentials['dbUrl'], $credentials['dbUser'], $credentials['dbPass'], true);
This doesn't happen all the time, just sometimes that connections get 'stuck'. I assume it might have something to do with something on the page not finishing (image not loading? external service stuck?). When does a script officially finish? Is it after the page loads completely?
I've thought of two possible solutions:
1. Using mysql_close.
2. Changing max mysql timeout (/etc/my.cnf)
3. Handle script timeout.
What reasons can cause a connection to become stuck in 'sleep'?
How would you suggest to resolve / further investigate the issue?

The > MASTER.txt is truncating the file before the paste actually completes the horizontal join. The answer is to output to a temporary file (e.g. MASTER2.txt) and then rename it (with the mv command) to the proper file name.
My Old Code:
paste MASTER.txt ${FILE}_trimmed.txt > MASTER.txt
Fixed Code:
paste MASTER.txt ${FILE}_trimmed.txt > MASTER2.txt && mv MASTER2.txt MASTER.txt

It is a fairly simple one (Name, Email, some fields like Adress and a Question Text) to send a simple text based email. The plugin I'm currently using is powermail.
When testing this form on my local version of the system it is sending the email to my adress without a problem - on the live system, however, it only displays the message
An error occurred while trying to call Tx_Powermail_Controller_FormsController->createAction(). Error: Required property 'form' does not exist.
what I already know:
The Problem seems to be that the html form is not submitting any POST data to the extension controller and therefore it has nothing to work with and is displaying that error ...
This is not a problem with powermail, building the form with other extensions (mailformplus, the built-in form plugin ...) has the same problem: no post data is sent.
It's also not a problem with POST-data on that server in general, calling a simple test script like this:
<form method="post" action="test.php?gettest=1" enctype="multipart/form-data">
<input type="text" name="test" value="" />
<input type="submit" name="submit" value="Testen" />
</form>
from a script not in the typo3-system displays
GET:
array (size=1)
'gettest' => string '1' (length=1)
POST:
array (size=2)
'test' => string 'test' (length=4)
'submit' => string 'Testen' (length=6)
correctly in test.php (which is just a var_dump($_POST/$_GET)).
However, building the above as a page in the typo3 system shows shows an empty POST array in test.php.
The problem is the same with realurl disabled.
Now my question is, could there be anything else in typo3 rewriting/redirecting request that POST-data might get lost? As I said, my local system works and I really can't findd any configuration difference between those two ... (but I'm also still far away from understanding every bit of the typo3 CMS' internal working)

Doctrine2 is lazy-loading if you don't configure something else, that means your $groups = $em->getRepository("orgGroup")->findAll(); won't return real orgGroup objects, but Proxy objects (Doctrine Documentation).
That means a $group object won't have it's description or orgGroupType value until you call $group->getDescription() or $group->getOrgGroupType() (then Doctrine loads them automatically), so you need to do that before writing the data into the JSON-response for the webservice. It won't work if you somehow loop through the object properties without using the getter methods.
I hope that was the problem :)

The flaking paint, if not accompanied by the cheesiness, is probably just a latex-over-oil issue. Even with multiple layers of cure-all primers and stain killers, some bad paints can't be cured.
Try a primer called 'bonding primer'. It should work well to gather up the particulates and really, as the name implies, bond the paintjob together. Go two good coats of this newer style 'paint amd primer in one" paint junk that's so popular now. It's not really primer, just a thickened paint, but it may help to isolate your issue.
If that fails, might be time to start thinking of furring the ceiling down and installing a new one.

The data:
repoServer -> myComputer -> NAT -> stagingServer
I have a local git repository server that is not exposed to the internet and a remote staging server on which I have to deploy my repo.
To do so, I ssh into the remote stagingServer with a reverse socket.
Current configuration for myComputer:
File: ~/.ssh/config
Host StagingServer
Hostname staging.acme.com
User username
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_username
ForwardAgent yes
on which I run:
ssh StagingServer -R 8022:repository.local:22
Current configuration for stagingServer:
File: ~/.ssh/config
Host repository
Hostname localhost
User git
Port 8022
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_deployer
on which I can run:
git clone git@repository:myProject.git
And all works fine, but... finally
The question:
Is it possible to specify in the ssh client config file (~/.ssh/config) to open the reverse tunnel so that I haven't to add -R 8022:repository.local:22

So in OAuth2 when making a request for Authorization Code then you need to send App ID to uniquely identify your app. After that, you are requested to send your App secret to get the Token.

No, it is not like the aether. It is still true that locally, there is no preferred reference frame. You don't even really need to think about spacetime to see what is going on. Consider a two-dimensional plane, parametrised by $(x,y)$, and roll it into a cylinder by identifying $(x,y) \sim (x + nL, y) ~\forall~ n$, where $L$ is some constant. Locally, this space is still perfectly isotropic, but globally, the $x$ direction has been picked out by the identification.
To see what this means, let's imagine drawing two straight line segments, each beginning at $(x, y) = (0,0)$ and ending at $(0,L)$. The first will just be $(0,t)~,~ 0\leq t\leq L$, and the other will be $(t,t)~,~0\leq t\leq L$ (which ends at a point equivalent to $(0,L)$ under the identification, and therefore the same point on the cylinder). Obviously the length of the first line is just $L$, but the length of the second line is $\sqrt{2}L$, by <PERSON>. Although any small patch of the cylinder is perfectly isotropic, we see here that the rotational symmetry is broken globally by the identification.
In spacetime, a similar thing happens, replacing rotational symmetry by boost symmetry.
Short answer:
Generally speaking, there is never a twin paradox: in any spacetime, just write down the metric in any coordinate system you like, and calculate the proper times for the two trajectories of interest. This tells you unambiguously which twin is older and which younger.

I arrived at the passport office before it opened (7am i think) and there was already a line and brought proof of my urgency (plane ticket) with all my documents with me. The most important part are the witness. I brought one witness with me and the other one was waiting by the phone. The witnesses are the only aspect that can delay the process, if you can get witnesses to pick up the phone directly or even to bring them with you, this will ensure a fast process.My passport was ready 5 hours later, printed and ready for pick up.

It doesn't seem to be using the hit_date index or url_id index.
I tried using a sub-select (select count(*) from stats where url_id = ... and hit_date >= ... and hit_type = 0) as aCount and it was faster and took 24s. Is there a way to make it less than 5s? The limit for the entire request is 30s.

However, it only allows to create "double" or "integer" precision for this coordinate variable. For external reasons, I need write the coordinate variable "time" as a float.
To do so, I use the following structure which consists in creating the coordinate variable separately from the dimension definition ( ie. using the option create_dimvar = FALSE described in the doc of ncdim_def)
timevalue= seq(0.5,10.5)
VAR1value= seq(10.2,20.2)
# define time dim, but without the time var
timedim <- ncdim_def( name = 'time' ,
units = '',
vals = seq(length(timevalue)),
unlim = TRUE,
create_dimvar = FALSE)
# define time coordinate variable
timevar <- ncvar_def(name = 'time',
units = 'days since 1950-01-01 00:00:00',
dim = list(timedim),
longname = 'time',
prec = "float")
# define another variable
var1var<- ncvar_def(name = 'VAR1',
units = 'unit1',
dim = list(timedim),
missval = -9999.0,
longname = 'VAR1 long name')
defVar<-list(timevar,var1var)
# creating ncfile (removing any previous one for repeated attempt)
ncfname='test.nc'
if (file.exists(ncfname)) file.remove(ncfname)
ncout <- nc_create(ncfname,defVar,force_v4=T, verbose = T)
# writing the values
ncvar_put(ncout,timevar,timevalue)
ncvar_put(ncout,var1var,VAR1value)
nc_close(ncout)
However, this returns the error :
"ncvar_put: warning: you asked to write 0 values, but the passed data array has 11 entries!"
Indeed, the resulting netcdf shows (ncdump) :
dimensions:
time = UNLIMITED ; // (0 currently)
variables:
float time(time) ;
time:units = "days since 1950-01-01 00:00:00" ;
float VAR1(time) ;
VAR1:units = "unit1" ;
VAR1:_FillValue = -9999.f ;
VAR1:long_name = "VAR1 long name" ;
I guess I need to force the dimension of the unlimited 'time' dimension upon creation, but i don't understand how to this in the frame of ncdf4.

you can't just drop out the values you are not interested in like that. You are trying to transform a time signal in the frequencies domain and in this way, I think you are altering the physics if the test. What you want to do is to remove the frequencies content of the signal corresponding to a certains speeds.
I would try to use a lowpass filter instead of removing or setting to 0 the values that you don't want. In this way, you can keep the same sampling rate and you are artificially modifying your test's data.
Vibration frequencies should be somehow related to driving speed (guessing higher frequencies for higher speed).
Hope this can be of any help
Ciao

Clients created from the same MessagingFactory instance will use the same underlying AMQP socket connection. For low throughput sending from the same process, then reusing the MessagingFactory is perfectly fine and preferred because it will cause fewer connections on the server-side (and connections are a limited resource). In the doc "Best Practices for performance improvements using Service Bus brokered messaging" that you link to, if you notice further down in the doc it says:
Multiple factories: all clients (senders in addition to receivers) that are created by the same factory share one TCP connection. The maximum message throughput is limited by the number of operations that can go through this TCP connection. The throughput that can be obtained with a single factory varies greatly with TCP round-trip times and message size. To obtain higher throughput rates, you should use multiple messaging factories
Which is the same message from the Event Hub documentation that you link to.

1dbfd4961734d2b67b67362e9a09e2a27dee0e3a6f3e79ed57e05a21b38a9755 | ['4d5f4da8a2ee40c69a45397661e344fb'] | I want to use ApexCharts as a means of visualization in Angular. ng-apexcharts is the npm package that acts as a wrapper. Because the default tooltip of ApexCharts doesn't fit my design, I'd like to make a custom tooltip component.
A custom tooltip can be specified the following way:
HTML:
<apx-chart ... [tooltip]="tooltip"></apx-chart>
TypeScript:
@Component({...})
export class LineChartComponent implements OnInit {
tooltip: ApexTooltip = {
custom: ({ series, seriesIndex, dataPointIndex, w }) => {
return "<div>Custom tooltip HTML</div>"
}
};
...
}
I have the following problem:
When trying to define a template like this as the tooltip HTML
`<div class="SOME_CLASS"><mat-card>${SOME_VALUE}</mat-card></div>`
and adding this to the component's CSS file
.SOME_CLASS {
color: red;
}
the class property and a non-HTML component like mat-card won't translate to the appropriate representations in the DOM. The string is just pasted instead. The HTML-structure can be found here.
What would be a way to make Angular bind this template correctly?
PS: I don't have access to the tooltip component so specifying
<tooltip [innerHtml]="SOME_VARIABLE"></tooltip>
won't work either.

When a new quote comes in, the calculations, which are done by a web worker, should trigger. Initially, I used this code to achieve the desired effect, but I noticed some flaws.
this.subs.sink = combineLatest([this.portfolio$, this.transactions$])
.pipe(sample(this.triggerCalculation$))
.subscribe(([portfolio, transactions]) => {
if (!portfolio || !transactions || transactions.length === 0) {
return
}
this.worker.postMessage({ message: 'calculate positions', payload: { portfolio, transactions } })
this.subs.sink = combineLatest([
this.store.select((s) => s.performance.positionMembers),
this.store.select((s) => s.quotes.currencies),
]).subscribe(([positionMembers, currencies]) => {
if (positionMembers.length === 0 || currencies === {}) {
return
}
if (portfolio?.watchlist && positionMembers) {
this.worker.postMessage({
message: 'calculate total on static change'
})
portfolio.watchlist.all.forEach((a) => {
if (positionMembers.includes(a._id)) {
this.subs.sink = this.store
.select((s) => s.quotes.quotes[a._id])
.subscribe((q) => {
if (q?.price) {
this.worker.postMessage({
message: 'calculate performance',
payload: {
id: a._id,
quote: q,
currency: a.currency,
currencies,
baseCurrency: portfolio.baseCurrency,
},
})
}
})
}
})
}
})
})
I already refactored this to be way better, at least I think so. I also improved some of the filtering:
this.subs.sink = this.transactions$
.pipe(
sample(this.triggerCalculation$),
withLatestFrom(this.portfolio$),
filter(([transactions, portfolio]) => portfolio?.watchlist && transactions?.length !== 0),
tap(([transactions, portfolio]) => {
this.worker.postMessage({ message: 'calculate positions', payload: { portfolio, transactions } })
}),
switchMap(([, portfolio]) => {
return combineLatest([
this.store.select((s) => s.performance.positionMembers),
this.store.select((s) => s.quotes.currencies),
of(portfolio),
]).pipe(filter(([members, currencies]) => !!members?.length && Object.keys(currencies).length !== 0))
}),
tap(() => {
this.worker.postMessage({
message: 'calculate total on static change',
})
})
)
.subscribe(([members, currencies, portfolio]) => {
portfolio.watchlist.all.forEach((a) => {
if (members.includes(a._id)) {
this.subs.sink = this.store
.select((s) => s.quotes.quotes[a._id])
.pipe(filter((q) => !!q?.price))
.subscribe((q) => {
console.warn('subscription')
this.worker.postMessage({
message: 'calculate performance',
payload: {
id: a._id,
quote: q,
currency: a.currency,
currencies,
baseCurrency: portfolio.baseCurrency,
},
})
})
}
})
})
My final question is how to get rid of the inner subscription (last block with portfolio.watchlist.all.forEach), where I create multiple subscriptions. The goal is to have as many subscriptions as quotes. I also change the whole object everytime new quotes are received, so subscribing the whole object would trigger even more often. Note that the subscriptions are created everytime the outer subscription triggers, so there might be an infinite number of inner subscriptions which exactly do the same. I only need them to be created once, but they should also reflect new quotes leading to new subscriptions.
If some experienced RxJS programmers could help me, I'd be really glad.

I have already added the button to each of the list items. I know I want to use the .filter() method to pass the state a new array that doesn't have the deleted to-do but I'm not sure how to do something like this.
Here is the App's main component:
class App extends Component {
constructor(props){
super(props);
this.state = {
todos: [
{ description: 'Walk the cat', isCompleted: true },
{ description: 'Throw the dishes away', isCompleted: false },

isCompleted: false };
this.setState({ todos: [...this.state.todos, newTodo],
newTodoDescription: '' });
}
toggleComplete(index) {
const todos = this.state.todos.slice();
const todo = todos[index];
todo.isCompleted = todo.isCompleted ? false : true;
this.setState({ todos: todos });

render() {
return (
<div className="App">

<input type="text" value={ this.state.newTodoDescription }
onChange={ (e) => this.handleChange(e) } />
<input type="submit" />
</form>
</div>
);
}
}
And then here is the To-Do's component:
class ToDo extends Component {
render() {
return (
<li>
<input type="checkbox" checked={ this.props.isCompleted }
onChange={ this.props.toggleComplete } />
<button>Destroy!</button>
<span>{ this.props.description }</span>
</li>
);

Any help and guidance would be appreciated :)

Does anybody know, whether I can stay logged in using cURL (this would be my favourite solution) or how I can use ftp with only one session in a shell script?

So here is how it works (as far as I can see):
When you open in-page analytics, you are first taken to https://www.google.com/analytics/reporting/iyp_launch
This page redirects to your site and adds a Google session to the url (like http://example.com/#gaso=THESESSION
The tracker now checks if the referrer is iyp_launch and gaso is set. If yes, it does not only load the tracker, but also injects the JS needed for requesting further data and rendering the overlays. This way, the JS is executed inside the frame (or window) and bypasses the same-origin policy.
Since Google Anaytics already tracks your visit (i.e. identifies you as the same user that viewed the previous page), it can from then on inject the additional JS along with the tracker until your visit is over (i.e. you close the page). This way, the overlays can be rendered again after you click a link.
So I guess the bottom line is this: Things like in-page analytics can be done if the site's owner has already trusted you by adding a script you control to his website (this is a good example why one should be very careful before doing such a thing). If you don't have that kind of access to the site, it might be impossible to bypass the same-origin policy - at least, I can't think of another way to do it (except maybe proxying all the requests through your sever, but that leads to other major problems).

When the user goes into the route "/products" I check to see if the state has the products if it does not then I fetch them.
componentDidMount(){
if(this.props.products.length <= 0){
var token = this.props.auth.token;
this.props.actions.getProducts(token);
}
}
But I am not sure if I should download all the products (1,000) and save them in the store or request them as needed. Example: I download 100 products and get all the pages and if the user wants to see the next 100 I fetch the next 100 products from server.
I will also be using this products in other parts of other forms.
What do you think?

When Vox is on (and it's set to send audio to the system default device), when I plug in the external soundcard, the system switches to the external, and very quickly switches back to internal speakers.
When Vox is off (quit), and I plug in the external soundcard - if it was default before, the system switches to it and stays on it.
So in my case, the Vox player makes the difference. Perhaps you could try with some other player, see what happens (and in this case - what doesn't).
Oh, this is a 2009 question... now I see... but anyway, this is what happens on my system. It's MacBook Pro Retina Mid 2012 running OS X 10.8.5.

It focuses on this piece of code (file name mainpp.c):
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
int status;
if (fork())
{
FILE *f=fopen("/tmp/gcc-trace","a");
fprintf(f,"----------------------------------------------------------------\n");
int i;
for(i=0;i<argc;i++)
{
fprintf(f,"%s:",argv[i]);
}
wait(&status);
fprintf(f,"\nstatus=%d",status);
fprintf(f,"\n");
fclose(f);
}
else
{
execv("g++.old",argv);
}
sleep(10);
return status;
}
This is used with a bash script:
#!/bin/sh
gcc -g main.c -o gcc
gcc -g mainpp.c -o g++
mv /usr/bin/gcc /usr/bin/gcc.old
mv /usr/bin/g++ /usr/bin/g++.old
cp ./gcc /usr/bin/gcc
cp ./g++ /usr/bin/g++
The purpose of this code ( and a corresponding main.c for gcc) is hopefully clear. it replaces g++ and logs calls to g++ plus all commandline arguments, it then proceeds to call the g++ compiler ( now called g++.old ).
The plan is use this to log all the calls to g++/gcc. ( Since make -n does not trace recursive makes, this is a way of capturing calls "in the wild". )
I tried this out on several programs and it worked well. ( Including compiling the program itself. ) I then tried it out on the project I was interested in, libapt-pkg-dev ( Ubuntu repository ).
The build seemed to go well but when I checked some executables were missing. Counting files in the project directory I find that an unlogged version produces 1373 whereas a logged version produces 1294. Making a list of these files, I discover that all the missing files are executables, shared libraries or object files.
Capturing the standard out of both logged makes and unlogged makes gives the same output.
The recorded return value of all processes called by exec is 0.
I've placed sleeps in various positions in the code. They do not seem to make any difference. ( The code with the traced version seems to compile much faster per file. I suspected that the exec might have caused the program to terminate while leaving gcc running. I thought that might cause failure because some object files might not be finishing when others need them. )
I have only one more diagnostic to run to see if I can diagnose the problem and then I am out of ideas. Suggestions?

However at a higher level, you may find it may work well for you.
I think a more detailed analysis of you data is called for. Saying that most of the time in the program is spent executing MOV and JUMp commands may be accurate, but it's not going to help yhou optimise much. The information is too low level. For example, if you know that integer arguments are good enough for dist2, and the values are between 0 and 9, then a pre-cached tabled would be 1000 elements--not to big. You can always use code to generate it.
Have you unrolled loops? Broken down matrix opration? Looked for places where you can get by with table lookup instead of actual calculation.
Most drastic would be to adopt the techniques described in:
http://citeseerx.ist.psu.edu/viewdoc/download?doi=<IP_ADDRESS>.8660&rep=rep1&type=pdf
though it is admittedly a hard read and you should get some help from someone who knows Common Lisp if you don't.

self._func_convert = func_convert
def read(self):

The argument func_convert allows a custom scaling function to be supplied once at instantiation that gets called to convert the data each time it's read. The function must accept a single int argument and return a single float. One possible example would be:
def adc_to_volts(value):
return value * 3.0 / 2**16 - 1.5
adc = Adc(adc_to_volts)
volts = adc.read()
Is there a standard way to document what the expected signature of func_convert is in the parameters section of the __init__ docstring? If it makes a difference, I'm using numpy docstring style (I think).

My normal approach would be something like this:
Put List A in column A and List B in column B. Put the following in C1:
=Not(IsError(Match(A1,B$1:B$600000,0)))
Then I would fill that down to C130000.
Obviously, this would work with two lists 100 items long. However, the lists are so large that this would take far too long for my computer to handle.
Is there a method that I can use in Excel that would work for lists this large without taking a month to process? Or do I need to start looking into other options?

I created made a named range using this formula: =OFFSET(Report!$B$1,1,0,COUNTIF(Report!$B$2:$B$30,"<>-"),1)
For that to work, I had to change all the empty cells to output "-" when empty in stead of "". I couldn't get COUNTIF to accept "<>""" or "<>" or any other weird tricks I tried. Using "-" was easier.
That makes a dynamic named range that changes size as I put data into the sheet. I named a similar range for everything I'm trying to chart (Approved Status, Call Ready, Not Ready). The chart was able to accept those names and now it's dynamically sized. If I only have three agents on the sheet, it shows three huge bars. With twenty, it shows twenty bars (exactly what I was looking for).
One other tip: I changed my first row to output "" when empty, so that COUNTIF(Report!$B$2:$B$30,"<>-") always returns at least 1 (otherwise you get annoying errors because you have a named range referencing a 0-length array).

That person said a char from that characters set can be used to make a person's name field blank in Twitch, Discord, etc, so they will show like they have no name.
I've tried to figure out what those chars really are by using Python's ord(). But I got TypeError: ord() expected a character, but string of length X found although I only put 1 char for the ord() argument and all things seem valid.
I'm taking a char from that character set, and try to put it in ord()
>>> ord(' ')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: ord() expected a character, but string of length 3 found
Then I continued by assuming that strange char is a set of chars.
>>> ' '[0]
'\ufeff'
>>> ' '[1]
' '
>>> ' '[2]
'\ufeff'
From what I've found \ufeff is a byte order mark (from here). But still it doesn't make sense to me, especially about how those chars can be packed together so it seems like it is only like 1 character from my computer.
And why some platforms treat it as a valid value, e.g for name.
Anybody could explain to me about this please?

Итак, в конструкторе надо метод Connect() вызывать только в случае подключения по TCP. Т.е. вместо
RpcSocket.Connect(RemoteEndPoint);
использовать
if (ConnectionType == ProtocolType.Tcp) RpcSocket.Connect(RemoteEndPoint);
При таком использовании сокет не привязывается к удаленному узлу. Именно по этой причине приходилось переподключать сокет в теле метода.
А в методе вызова процедуры CallBroadcast() часть с TCP-соединением повесить на исключение, и оставить только SendTo() для UDP подключения. А вообще я переписал функцию так, чтобы ее можно было использовать и для единичного вызова. Получилось примерно следующее:
public Dictionary<EndPoint, RpcReplyMessage> CallBr(RpcCallMessage callProcedure)
{
Dictionary<EndPoint, RpcReplyMessage> replies = new Dictionary<EndPoint, RpcReplyMessage>();
CallMessage = callProcedure;
bool waitReplies = ConnectionType == ProtocolType.Tcp ? false : true;
EndPoint ep = new IPEndPoint(IPAddress.Any, 111);
byte[] mes = callProcedure.ToBytes();
byte[] finalmes = new byte[sizeof(uint) + mes.Length];
Buffer.BlockCopy(NetUtils.ToBigEndianBytes(xid), 0, finalmes, 0, 4);
Buffer.BlockCopy(mes, 0, finalmes, 4, mes.Length);
switch (ConnectionType)
{
case ProtocolType.Tcp:
if (!RpcSocket.Connected) RpcSocket.Connect(RemoteEndPoint);
RpcSocket.Send(finalmes);
break;
case ProtocolType.Udp:
RpcSocket.SendTo(finalmes, RemoteEndPoint);
break;
default:
throw new Exception(ConnectionType.ToString() +
" protocol have not realization of function Call().");
}
do
{
try
{
byte[] buff = new byte[1024];
int recSize = RpcSocket.ReceiveFrom(buff, ref ep);
if (!(CheckXID(buff) && CheckReceive(buff))) continue;
recSize -= sizeof(uint);
byte[] nbuff = new byte[recSize];
Buffer.BlockCopy(buff, sizeof(uint), nbuff, 0, recSize);
replies.Add(ep, new RpcReplyMessage(nbuff));
}
catch (SocketException)
{
waitReplies = false;
}
}
while (waitReplies);
return replies;
}
Так же добавил условие на то, чтобы при TCP-подключении сокет принимал данные только однократно.
Касаемо фильтрации по порту отправителя. Видимо это можно устроить только программно проверяя порт, с которого был отправлен ответ.

It uses QtWebKit (A Qt port of the WebKit rendering engine) to render a web page, and converts the result to PDF or image format of your choice, all done at server side.
Because it uses WebKit, it renders everything (images, css and even javascript) just like a modern browser does. You can fine tune the parameters such as tweaking the JavaScript execution grace period.
In my use case, the results have been very satisfying and are almost identical to what browsers would render.

First thing in the function 'get_absolute_url', in kwargs={'pk':self.pk}), you have to delete 'self.' before 'pk', It's already defined as self_function so it will return a self_primary_key for the image. It will be apear like :
def get_absolute_url(self):
return reverse("image_detail",kwargs={'pk':pk})
Now, you sould to read all the image pk's in your database, not only the pk for one image, because you will have a lot of images, so if you return only one pk, the browser will show you the first image only, so use a for loop, and your code should apear like :
...
<div class="col-lg-3 col-md-4 col-6">
{% for image in p.images.all %}
<div class="d-block mb-4 h-100">
<img class="img-fluid img-thumbnail" src="{{ p.image.url }}" alt="hi">
</div>
{% endfor %}
</div>
...
Also in the class 'DayImage' you have to delete the 'self.' before the 'pk' in the return.

I will be staying at a hotel near Times Square, but I would like to avoid driving in the city. It seems that the easiest approach would be to drop off the rental car somewhere in the NYC suburbs and transition to mass transit. Are there any train stations where I could do this when coming from the west (probably via I-78)?
This is, of course, assuming that the rental car option is cost-effective. I'm currently researching to decide whether it might be a better idea to just fly (in which case getting to mass transit is straightforward). However, in order to evaluate the potential drop-off cost for the rental car, I wanted to identify some potential candidate locations where I could make the transition so I can get some rental car quotes.

You can also use CAST('2013-09-05T10:10:02Z' AS DATETIME) which does not require a format definition as in STR_TO_DATE().
I would consistently get: Error: Truncated incorrect datetime value: '2011-10-02T23:25:42Z'
I fixed it by casting the value to an @ variable before using it in my query. Here is an example in a Stored Procedure:

Since about 2015, the best way -- in my opinion -- to enter code is with Stack Exchange's code snippets. This can be done by clicking the little icon to the right of the picture/image icon, or by using the keyboard shortcut CTRL + M (CMD + M on Mac). This is the best way I have found to make sure your code appears as code and doesn't not get accidentally translated. You can past mixed html/javascript/css all in the html box, or you can separate each part into individual boxes.
Works much like jsfiddle, without needing to leave Stack Overflow, or rely on a link that might disappear in a few years.

That's just before the footer of my page:
<div class="modal" id="modal">
<span class="close" id="close">✖</span>
<img class="modal-content" id="modal-content">
</div>
How I show the modal:
function showModal(name) {
modal.style.display = "block";
modalImg.src = document.getElementById(name).src;
}
And here is my styling:
/* Background when image is shown */
#modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(119, 119, 119); /* Fallback color */
background-color: rgba(119, 119, 119, 0.9); /* Black w/ opacity */
}
/* Image */
#modal-content {
/* Horizontally center image */
margin: auto;
/* Sizing */
display: block;
max-width: 90%;
max-height: calc(100vh * 0.5);
width: auto;
/* Zoom (image gets bigger) on open */

animation-duration: 0.6s;
/* Style */
border: 10px solid #ffffff;
box-shadow: rgba(0, 0, 0, 0.54) 0px 0px 7px 4px;
/* Vertically center image */
position: relative;
top: 40%;
transform: translateY(-40%);
}
@keyframes zoom {
from {
transform: scale(0)
}
to {
transform: scale(1)
}
}
/* Close Button */
#close {
/* Position */
position: absolute;
top: 10px;
right: 10px;
/* Style */
color: #ffffff;
font-size: 20px;
font-weight: bold;
transition: 0.3s;
background-color: #000000;
border: 3px solid #ffffff;
box-shadow: rgba(0, 0, 0, 0.5) 0px 0px 25px 3px;
/* Makes the Button round */
border-radius: 50%;
padding-left: 7px;
padding-right: 7px;
padding-bottom: 3px;
}
/* Change cursor when pointing on button */
#close:hover,
#close:focus {
text-decoration: none;
cursor: pointer;
}
/* 100% image width on smaller screens */
@media only screen and (max-width: 700px) {
.modal-content {
width: 100%;
}
}
The problem is that
position: absolute;
top: 10px;
right: 10px;
positions the close button in the top-right corner of the page, not at the top right corner of the image.
How can I fix that?

p.s. On my development environment it all works since im calling from localhost/index.html requesting to a localhost/getData (through a reverse proxy to localhost:8069/getData for cors). But when i put it on our real server it responds with some missing session error

for company in self.pool('res.company').browse(cr, uid, uid):
company.vat <=== code breaks here
If i use the administrator (uid 1) account i see company.vat. But if i use any other account (which have permissions to res.company) i get a message: "One of the documents you are trying to access has been deleted..."
Is this a permission issue or a coding error of sorts? Mind that if I hard code 1 instead of uid as a parameter to browse function it works.
Thank you

The latter equation implies that $N$ is a solution of the quadratic $ \frac{r}{q}x^2+(1-r(1 - \frac{1}{q}))x + 2 - r = 0$. The roots are $$\frac{-1+r(1-1/q) \pm \sqrt{(1 - r(1-1/q))^2 - 4r(2-r)/q}}{2r/q}$$ | 260fd0135745b624c1b301f7a96d1cdadf29da24adb64d247a9053b3ad9b6876 | ['4f1fc17956be46d194c25d6395cd2e34'] | Since $\lim_{m \to \infty} s_m(j) = g_j'(x) < \infty$, you can let $M$ be large enough so that $m \geq M$ implies $s_m(j) \leq g_j'(x) + 2^{-j}$. This is an integrable function which eventually dominates $\{s_m\}$ therefore. It is integrable by the hypothesis that the sum is finite.
Also, I'd appreciate a comment from whoever downvoted. |

class Counter {
public:
int* j = new int[5];
}
A pointer variable is initialized as a data member. If in my copy constructor, I have something like
int* j = new int[7] OR int* j = new int[5](),
therefore initializing the the data member as well, will it create a memory leak for the first one since it wasn't deleted beforehand? Or will the original data member not even initialize?

I understand the uniformly distributed part, but do you have to know the range too? If the range is not provided, when creating the auxiliary array during bucket sort, could you instead simply create a dynamic array (ArrayList) which can expand by itself?

I highly recommend reading this topic : Context.startForegroundService() did not then call Service.startForeground()
From my experience (Working on the same scenario), you will face lots of unexpected bugs on different devices and different SDK versions by starting a Foreground Service using startForegroundService command. Just use the old startService method and you'll be fine.
Also what's the purpose of using START_STICKY while it's a Foreground Service and it's guaranteed to be running as long as the ongoing notification displays?

The HttpClient.get() method parsed the JSON server response into the anonymous Object type. It doesn't know what the shape of that object is.

console.log(basic['companyName']) <- I should get the Json Object.
console.log(JSON.parse(basic)); <- I should not do this.

I use JSON.parse to get the data. However, it seems not correct.
So my question is what is the correct way to get the Json via the HttpClient?

However, it's not a documented method for overriding, so know that doing so you could run into issues in different versions of Eve.
The way I modified the method was to have it look for a Cookie header, and if found, try to get an auth token from it. If it finds one and check_auth returns true, call set_user_or_token and return.
If there's no cookie header, or the token does not check_auth successfully, fall through to the parent class' authorized method to handle other cases (such as an Authorization header).
class MyTokenAuth(TokenAuth):
def authorized(self, allowed_roles, resource, method):
auth = None
if request.headers.get("Cookie"):
auth = self.try_to_get_auth_from_cookie(request.headers.get("Cookie"))

I take the eve_swagger blueprint that's provided, and add a before_request with an authorization function. Something "like" this:

from flask import current_app as app
def authorize_swagger:
# my auth logic
eve_swagger.swagger.before_request(authorize_swagger)
app.register_blueprint(eve_swagger.swagger)
The result of doing this is now when I call the default /api-docs route, my authorization function is called and processed before the request. This way if my function decides the request is not authorized, it can stop the request.
