I'm using Firefox 68.0.2 (64 bit) and a habit that I have been forming involves "bookmarking" webpages on a daily basis by pulling the site URL directly from the displayed address in the control at the top of the page as it appears in the browser onto the Bookmarks Toolbar (which is loaded with titled folders, as you would imagine, accounting for the passage of time/greater utility/etc). If a user does what I do in this way, he can right-click on any "saved" url and get a PROPERTIES dialog box to pop up and allow access to four things "Name", "Location", "Tags", and "Keyword".
So, a shortcut with properties. Considering a shortcut ... unless I saved a whole webpage to disk and then opened that local page in the browser and THEN pulled the URL to my Bookmarks Toolbar and then set about adding KEYWORDS to that local reference through the PROPERTIES/Keywords control, I would expect that by adding keywords to a link like this, to a REMOTE webpage on some server somewhere on the internet, that such a "save" would involve tracking those added keywords locally (I know it's through a SQLite database in the Mozilla folder) and I can assume that this is indeed what the local SQLite database keeps track of, among other things.
Well the behavior I observe is odd then; why does saving a webpage (as .html document for instance) to a location on a drive on my computer, placing a link to it in the bookmarks toolbar folder of choice, altering the links Properties/Keyword by adding a descriptive component, then saving that add, CHANGE THE PROPERTY OF THAT LOCAL WEBPAGE ... NOT just the link of the bookmark toolbar? It does. Somehow.
Try this yourself by saving a webpage to disk, opening that saved webpage in firefox browser, sliding a link from the address control to the browser toolbar, then opening that link. Once the page is verified "here" right-click the link again, choose Properties, see the Keywords control box, and type in some new/other term. AND now, this is the important part, copy this link, paste it somewhere else in the toolbar (behind a folder perhaps), open it so the local webpage is displayed, click once again on the link, get the properties/keyword control ... see that duplicate keyword you just typed in for the original, DELETE that keyword, and type in another keyword then save.
See my confusion:
Load the original link again, look at properties/keyword and see that the original now has the changed keyword (the original keyword has been erased and replaced with the copy's keyword).
This shouldn't be happening. Despite the fact that the link on the toolbar is connected to a local webpage and not some remote page address found in the browser's lookup under SQLite/Mozilla database, the keyword should still be associated with the LINK ALONE, NOT THE LOCAL FILE.
Yes?
Is not a webpage keyword (remote) stored in the SQLite database? Is not the sole keyword lookup for a given Bookmarked URL on my firefox toolbar being facilitated by a browser's delve into that SQLite data to return the keyword in that property's keyword {space} (for lack of a proper name for an association that a database uses to link such things under cover of it's functionality)?
How could I possibly be dis-explaining this to myself?

I am dismayed to find no tangible examples of its usage - nothing but casual mentions of what people did to make it work.

Hi there:
I have to debug two branches of the same codebase side-by-side (a development branch vs a release branch), as we're seeing unexplained differences in behaviour between them. I've opened two copies of VS 2019 (latest patch v18.6.3 at 16th Dec 2020), and when launching them, one will succeed, and the other will throw up an error message:
One or more errors occurred.
Failed to launch the debug adapter. Additional information be be available in the output window.
Cannot connect to runtime process, timeout after 10000 ms - (reason: Cannot connect to the target: connect ECONNREFUSED 127.0.0.1:4318).
What I've tried:
- Making sure that each web project is set to start on a unique port number, I've selected 53199 for one branch and 53200 for another.
- Delete the applicationhost.config inside .vs, restart VS and let it recreate.
What I've noticed:
- The two Visual Studios try to launch as tabs in the SAME Chrome instance. I loaded a random different project from another codebase and that project launched its own new Chrome instance.
- Inside each applicationhost.config, in the <sites> section, BOTH projects have:
<site name="foo.Web" id="2">
- Their site "id" is the same, but each config file does have the correct virtualdirectorypath for its project location.
- this is new behaviour (maybe a new bug?) and I've been able to run this configuration plenty of times in the past.
- the output window contains only this:
Verbose logs are written to:
C:\Users\Bar\AppData\Local\Temp\visualstudio-js-debugger.txt
The program '' has exited with code -1 (0xffffffff).
The program '[21072] iisexpress.exe' has exited with code 0 (0x0).
- as each site starts up, the visual studio debugger log shows a --remote-debugging-port which is unique for each site, so no conflict there...
Since we're using TFS version control, "two branches" in this context means two completely different folders on disk, each with a full copy of the project source inside. I cannot see why these projects interfere with each other. Each one launches into debug successfully on its own and then the other won't launch.
Can I "fool" VS / IIS Express by manually changing the site "id" or "name" in applicationhost.config?
Any help gratefully appreciated!
-- edit: there are workarounds, e.g. using two different browsers, but still would like to clarify whether it's me or VS or IIS express causing this, and whether it can be fixed!

You could always just set them up as their own sites in IIS and attach the debugger of each instance of VS to the relevant site. I'm pretty sure what you're trying should work anyway so don't know if there is something odd going on with your project structure or what the sites are doing. I'd try the IIS route though as I know that definitely works.

I'm trying to diagnose an issue with a mod I wrote.
So I start with $rs2 = -1, then I increment $rs2, but when I print $res2 in the table cell, $rs2 goes ...
0
1
0
1
1
1
1
1
I thought since $rs2 is the origin number to feed into mod, that the number should increment.
0
1
2
3
4
5
6
7
It's works on the other function with the same mechanics here. Just not this one.
I haven't worked PHP since 2005, so I'm a bit rusty.
$rs2++;
$stripe2 = ($rs2 % 2 == 0) ? "rowStripe" : "";
echo "
<tr>
<td class='report-table-body-20 $stripe2'>
<p class='report-table-body-p'> $rs2 $equip_cat_name</p>

$correo = $_POST['correo'];
$usuario = $_POST['usuario'];

$contrasena = hash('sha512', $contrasena);
$query = "INSERT INTO usuarios(nombre_completo, correo, usuario, contrasena)
VALUES('$nombre_completo', '$correo', '$usuario', '$contrasena')";
$verificar_correo = mysqli_query($conexion, "SELECT * FROM usuarios WHERE correo='$correo' ");
if (mysqli_num_rows($verificar_correo) > 0) {
echo '
<script>
alert("Este correo ya está registrado");
window.location = "../index.php";
</script>
';
exit();
}

I don't really want to "maintain a web site" but I want to expose some computing functionality for a hobby of mine.
Excel is driving me to tears.... So I am thinking perhaps I could have a single page static SPA!
But most web tech drive me to tears, me think would be nice do a Blazor SPA! Is it possible?
One with 0 server side setup! That I can just drop on web app folder somewhere?
Any links? tutorials?

hi all,
I am going to build an asp.net core website and an asp.net core webapi. My question is that from design perspective, should I just call into the webapi to get data for my website? or just call into the database to get data directly?
It looks like calling the webapi would promote separation of concerns and I don't have to expose my database connection strings in multiple places, but I am afraid there is a performance hit that will impact the performance of the load time of the website.
Any insight is greatly appreciated.

Quote: My question is that from design perspective, should I just call into the webapi to get data for my website? or just call into the database to get data directly?
This is a preference-based and a scenario-based question. In my own application that I have, I am redirecting all the database related stuff through API, and this has decreased the attack surface a lot (I can secure the database requests at one place).
Also, if you route all the database traffic to ASP.NET Core Web API, you can develop the frontend independently—in future you can replace ASP.NET Core MVC with something like a React or Angular framework for frontend, and you can easily integrate the application in a mobile application; native, Xamarin or Flutter.
Quote: It looks like calling the webapi would promote separation of concerns
Correct, like I said earlier.
Quote: I don't have to expose my database connection strings in multiple places
Yes, and no. You still can prevent exposing the database connection string by using variables on your hosting environment and then reuse that value in all your processes. This part depends entirely on where you are hosting your application.
Quote: but I am afraid there is a performance hit that will impact the performance of the load time of the website.
No, do not worry about this part.
If you create two applications, you are going to launch them separately and that can add 3-5 seconds of load time, but it would be much easier to scale the applications in the future. This will help you in handling the load like a pro.
Also, load time depends on how many users are you expecting to get? If there will be a lot of users (like thousands of active users) then try caching your website and the queries, so you do not send duplicate queries to the database for at least an hour.
Here are a few more ideas to improve the performance:
- Deploy your application as a stateless instance (try to move all the memory and state, e.g. session information to a database)
- Add a caching layer to your service
- Try to add scaling to your website (depends on the host environment)
- If you scale a stateless website, you can utilize caching and database to handle more requests and provide service to more users
- Keep separating the different domains inside your application to their own services (Microservice pattern)
I hope this helps you understand the bigger picture.

Thanks Afzaal, this is very insightful and answer most of my concerns. your ideas to improve performance aligned with what we had in mind except for number 1 that I am not sure if I understand.
Did you mean that I will need to make database calls through the webapi to get the session state, like if I have a survey engine, I will have to post every question that the user answer so he or she can come back to it later? if not, Can you give a brief example what you have in mind?
Thanks and greatly appreciate your help.

Quote: Did you mean that I will need to make database calls through the webapi to get the session state,
Not specifically, but just outproc the session and other "state" information.
Take a look at this for inspiration: ASP NET Core MVC - How to configure Out of Process Session State? - Stack Overflow
Quote: if I have a survey engine, I will have to post every question that the user answer so he or she can come back to it later?
Correct, so that none of the information is stored only in the ASP.NET Core process. This can help you scale the application as well, since your users are not stuck with using a specific process and load balancer can easily balance the traffic regardless of the survey state.

the post about out of process session state is interesting. still need time to digust the topic as I am not familar with it at all. I believe I have a basic idea how to go about doing this now. thanks again for the help!

You should separate the database code from the controllers and views. I created a database class implementing an interface that is passed to the controllers, providing methods to obtain the required data from the database. Thus there is a minimal common interface between the web site and the database code, and the web site knows nothing about the database. This allows testing of the database code with a desktop test harness. It also allows easy replacement of the database code if for example I change database provider.
I used Dapper for database access, but PetaPoco is better IMO.

hi Leif Simon Goodwin,
Yes, I believe that calling into an webapi is better in terms of separation of concern, and I have started doing that for my project. I've never heard of petapoco before and it looks interesting. I am just using good old ADO.NET using queries and loading data to POCOs.

I used to use Entity Framework. Everything seemed to work well enough to get me hooked, until there are more complicated examples, such as pull fields from different tables using a stored procedure and try to update the fields in the object afterwards, that will get me all the time ...
