networking – 1 internt connection, 2 routers, split into 3 separate networks, ethernet being its own network

I have one internet connection coming from coax to hitron coda modem/router. There are 3 ppl in the home, and I want to separate networks for all 3 of us. I would like to have ethernet on its own network as well. Is it possible? I have tried to connect r700 to Hitron with ethernet cable but my concern is if the 3rd guy connects into a port on the router am i in jeopardy?

oracle – Connect Application with separate DB links from same server

My application is connecting to our internal Oracle Server. Our internal Oracle server connects with a third-party server using a DB link. Now, our internal oracle needs to create another DB link to second third party. So our application currently we have,

Application >> connects to internal Internal:SomePort >> connects to third-party ThirdPartyIp:SomePort(via DB link)

Now, all our queries (from the application) are without @DbLink

Now we have created a new DB link on the same internal server,

Application >> SameInternalServer >> connects to another third-party ThirdPartyIp:SomePort(via DB link)

Is it possible to use different connection strings for different third party DB? or we will be struck to @DbLink syntex from the application?

For Third Party, we can use,

select * from ThirdPartyTable

But for the second we have to use,

select * from ThirdPartyTable@DbLink

Any way to mitigate avoid @DbLink because we have DB structure is same for both third-party servers.

sharepoint online – Can you separate multiple values in a single string in @currentfield delimited in some way to make each value a hyperlink

I’m currently using MS’s column formatting JSON to turn a field’s string entry into a URL using the following to automatically make the ticket number entry a clickable hyperlink to our zendesk for the respective ticket number:

  "$schema": "",
  "elmType": "a",
  "txtContent": "@currentField",
  "attributes": {
    "target": "_blank",
    "href": "='' + @currentField"

However, if we have multiple tickets for the same issue, it would be nice to be able to do the same for multiple values that are separated by a space, comma, or what have you so that each ticket number would link to it’s respective ticket. Is this possible? Using Office 365 hosted sharepoint if that matters any.

performance – What can cause higher CPU time and duration for a given set of queries in trace(s) ran on two separate environments?

I’m troubleshooting a performance issue in a SQL Server DR environment for a customer. They are running queries that consistently take longer in their environment than our QA environment. After analyzing traces that were performed in both environments with the same parameters/filters and with the same version of SQL Server (2016 SP2) and the exact same database, we observed that both environment were picking the same execution plan(s) for the queries in question, and the number of reads/writes were close in both environments, however the total duration of the process in question and the CPU time logged in the trace were significantly higher in the customer environment. Duration of all processes in our QA environment was around 18 seconds, the customer was over 80 seconds, our CPU time was close to 10 seconds, theirs was also over 80 seconds. Also worth mentioning, both environments are currently configured to MAXDOP 1.

The customer has less memory (~100GB vs 120GB), and slower disks (10k HHD vs SSD) than our QA environment, but but more CPUs. Both environments are dedicated to this activity and should have little/no external load that wouldn’t match. I don’t have all the details on CPU architecture they are using, waiting for some of that information now. The customer has confirmed they have excluded SQL Server and the data/log files from their virus scanning. Obviously there could be a ton of issues in the hardware configuration.

I’m currently waiting to see a recent snapshot of their wait stats and system DMVs, the data we originally received, didn’t appear to have any major CPU, memory or Disk latency pressure. I recently asked them to check to see if the windows power setting was in performance or balanced mode, however I’m not certain that would have the impact we’re seeing or not if the CPUs were being throttled.

My question is, what factors can affect CPU time and ultimately total duration? Is CPU time, as shown in a sql trace, based primarily on the speed of the processors or are their other factors I should be taking in to consideration. The fact that both are generating the same query plans and all other things being as close as possible to equal, makes me think it’s related to the hardware SQL is installed on.

separate list of programs in html/javascript coming from wordpress/php

I have a html/php code as shown below which displays list of links coming from wordpress.


<header class="entry-header container grid-flex">
    <div class="flex-item -sm-50">
</header><!-- .entry-header -->
<div class="entry-content">
    echo "<pre>"; print_r($all_list); echo "</pre>";   // Line A
    echo "<hr>";
    echo "Active List<br>";
    echo "<pre>"; print_r($active_list); echo "</pre>";   // Line B
    echo "<hr>";
    echo "Passive List<br>";
    echo "<pre>"; print_r($passive_list); echo "</pre>";   // Line C
    // Load the thumbnails view
    get_template_part( 'parts/content-list-thumbs' );     // Line D

Line A displays following list of links:

Line B displays following links:

Line C displays following links:

The code inside content-list-thumbs file coming from Line D is:

html/js code:

<ul id="list-thumbs">
    while (have_posts()) : the_post();
        <li class="list-grid__thumb list-grid__item">
            <a class="list-grid__img-link" href="<?php echo esc_url(get_the_permalink()); ?>">
                <?php if (has_post_thumbnail()) { ?>
                    $image_id = get_post_thumbnail_id(get_the_ID());
                    CPACImagesthe_img_fit_figure($image_id, 'list-grid__image', '(min-width: 650px) 50vw, 100vw', false); ?>
                <?php } ?>
    <?php endwhile; ?>

The above html/js code displays list of images associated with Line A.

Problem Statement:

What I want to achieve from the html/js code above is I want to display list of images associated with Line B and Line C with a separator.

Line B images

Line C images

machine learning – How to use classify to separate lines and circles

I generated lines and circles:

lines = Table[
    Line[{{RandomInteger[{0, 10}], 
       RandomInteger[{0, 10}]}, {RandomInteger[{0, 10}], 
       RandomInteger[{0, 10}]}}], ImageSize -> 10], {x, 1, 20}];
circles = 
    Circle[{RandomInteger[{0, 10}], RandomInteger[{0, 10}]}, 
     RandomInteger[{0, 20}]], ImageSize -> 10], {x, 1, 20}];

and put them into a classifier

c = Classify[{lines -> "lines", circles -> "circles"}]

the training was successful with no errors, but when trying to test the classifier with:

test = Graphics[Line[{{0, 1}, {0, 2}}], ImageSize -> 10]

I get the error:

ClassifierFunction::mlbddataev: The data being evaluated is not
formatted correctly.

And I do not understand what the problem is. Can somebody tell me, how to correctly format the data?

java – How to separate elements from a black/white image using OpenCV and some algorithms

Hi I am doing a proyect where I have to clasifie the parts of an electric circuit( resist,inductances…)
The problem is that I don´t know how to do to separate the elements from the circuits and later clasifie it with SVM or something similar.The circuits can be drawn by hand or not.

In this example I managed to eliminate all the parts that are not from the circuit( tittles, noise…)
I transformed it to a B/W image and theres where I am stuck.

I know I could use the connectedComponents function but I want to do something more profesional because in this picture you can see only rectangles and circles but there are other images where these forms change, so I need something like and algorithm or a way to work to take them from the black/white circuit and later clasifie it as I said.

Thanks for the help.

linux – Now that TIgerVNC has dropped command line support, is there any fork that is maintaining the ability to run a separate vnc server?

See for some context.

Basically, TigerVNC has decided to drop support for command-line usage, and is only working via desktop sessions.

Is there any tool that exists, perhaps a fork, to continue to use vncserver from the command line, with an entirely separate session from the desktop? (This is necessary because modern desktop environments like kde and gnome can only run one instance at a time. No, connecting to the desktop display is not an option)

winforms – How to separate “unmanaged” and “managed” code in my C++ project

I am developing a project using C++ and WinForms. It is a geometry project, which is why I have to use C++, because of the geometry library CGAL. I chose to use WinForms for the UI because compared to the other C++ windows UI options it seemed rather easy to use. However, after some research online I realized that WinForms for C++ makes use of managed code and that managed C++ is oftentimes a factor 2 slower than unmanaged C++. The project is about implementing a competitive algorithm, so the running time is very important. The project will have a very simple UI form to select some parameters for the project and the running time will only be tracked for the actual computation part of the project, not for the UI interaction.

Will using WinForms, in this case, slow down the running time of the geometrical computations? Or is it okay, because the geometrical part of the code is in an “unmanaged” part. How can I make sure that it is “unmanaged”?
