Is there a way to tell it not to do that?\n\nI first noticed this issue while testing a simple app that was using internal links; testing with JavaScript turned off worked fine, but with JavaScript turned back on, I noticed that each link actually had an associated piece of JavaScript that I didn't write and can't control.

"Problems with Kentico and Wildcard URLs after upgrade to 11",
"Foreword:\nThis question may be too specific for Stack Overflow.\nI have also posted it on the Kentico forums: https://devnet.kentico.com/questions/problems-with-kentico-and-wildcard-urls-after-upgrade-to-11\nSynopsis:\nAfter upgrading to Kentico 11, the wildcard setup I have no longer seems to be working properly. After a lot of digging and research, I think the problem is somewhere in the mechanism that Kentico uses to map the wildcard values to URL parameters... but I don't know how to look into that process to try and figure out where it's going wrong and/or how to fix it.\nDetails:\nI have a page set up with the following "Standard URL or wildcard" value set:\n/Invest/Communities/{ProvinceName}/{EconomicRegionName}/{RegionalDistrictName}/{CommunityName} This page also has a single alias of /Invest/Communities/Province but I'm not sure that's doing anything for me.\nThe page itself contains a single custom control, which has a User control virtual path of ~/<project>/WebControls/Communities/Community.ascx\nPrior to the upgrade, this URL: /Invest/communities/myProvince/myEconomic/myRegional/myCommunity/ worked fine - if I set a breakpoint at the start of the Community.ascx.cs Page_Load {} method, the breakpoint would get hit, and I could pull those four values out of the query string (via e.g. HttpContext.Current.Request["ProvinceName"]).\nAfter the upgrade, the same URL is not hitting the breakpoint, and is instead directing me to a 404 error. However, if I manually re-write the URL to /invest/communities/profile/?ProvinceName=myProvince&EconomicRegionName=myEconomic&RegionalDistrictName=myRegional&CommunityName=myCommunity the page works as expected. Breakpoint hit, values can be pulled from Request object.\nIt seems as though something has gone wrong with whatever mechanism does the value mapping... but as that's stuff built into Kentico, I'm not clear on how to look deeper into it to see where it's failing.\nOther things I have tried:\n\nRe-signing all macros. This fixed a different problem I had after the upgrade, but did not help with this issue.\nOn the Pages > URLs tab: changing from Standard URL or wildcard to Route\nFound this advice in a forum post somewhere; doing this made it so that I would hit the breakpoint in the control again properly, however none of the wildcard values were available in the Request object any more. Not good.\n'Saving' on the page tab, the URLs tab, and other places in case somehow there was something corrupted that re-saving would somehow reset. Total shot in the dark, but in very rare cases this has worked before. No help here."

"sensor fusion with rotation vector sensor",
"I’m working on a project. I want to combine three sensors: accelerometer, gyroscope and magnetometer. I found Complementary filter or Kalman filter can be use for this. Then I came across with rotation vector: “Virtual sensor fuses Accelerometer, Magnetometer and Gyroscope in a Kalman filter”. This sentence confused me. So this means I can just use rotation vector for combining sensors and I don’t need to use filters I mentioned above? Hope you can answer me. At least some suggestions about this topic might help me. I will be glad.\nThanks for your time."

"PHP mail script using up huge amounts of resources",

The PHP script I use (and have used before with no issues on a different hosting service) lags the entire server (which has 8GB RAM by the way) for as long as it is sending emails.\n\nNow, I talked to the hosting support people, asking if something's wrong with their mail server, or if there are some outgoing mail limitations or whatever, and they said no. In fact, they are adamantly claiming that it's a coding issue. I highly doubt that, but it's possible the script was slightly altered since its last use a few months back, so I'm sharing the script below, and a typical email I would be sending is in the $content variable.\n\nThe question is, can someone see a reason why this code would eat up resources like crazy?\n\nI have checked the MySQL logs, and the query itself (which gets emails from the database) isn't slow.

"Simple Javascript animation in Gatsby",
"I'm new to learning React and Gatsby, and am trying to find the best way to apply simple a Javascript animation to a DOM element within a component. I know how to handle component events with onClick etc, but say for example I want to continuously change the colour of a <span> in my Header.js component every 2 seconds.\nimport React from 'react';\n\nexport default function Header() {\n return (\n <header>\n <p>This is a <span>test!</span></p>\n </header>\n )\n}\n\nI'd then want to use some JS like:\nconst spanEl = document.querySelector('header span');\nlet counter = 0;\nconst changeColor = () => {\n if (counter % 2 == 0) {\n spanEl.style.color = "red";\n } else {\n spanEl.style.color = "blue";\n }\n counter++;\n if (counter == 10) counter = 0;\n}\nsetInterval(changeColor, 2000);\n\nI found that I could put this inside a script tag in html.js before the closing body tag, but is there a way to keep this functionality within the component? Do I need to completely rethink my approach when working within this framework?"

"Object references of model getting lost on view",
"I'm triying to implement a view where I pass it an object with certain references to other objects, edit some fields and get it back to persis, the problem is those references are coming back as null once i get the object back, heres my implementation:\n\nthis is the model i pass to the view:\n\npublic class TicketCreationModel\n{\n\n\n public SupportItem item { get; set; }\n public Ticket ticket{ get; set; }\n public Employee employee{ get; set; }\n\n\n\n\n}\n\n\npretty simple, the model has a ticket, a support item and an employee. Now heres the method where I pass my model to the view:\n\npublic ActionResult AssignSupportItem(int supportItemId)\n {\n\n Ticket ticket = GetTicket();\n ticket.Item = repo.GetSupportItemFromId(supportItemId);\n TicketCreationModel model = new TicketCreationModel();\n model.employee = ticket.AccountableEmployee;\n model.item = ticket.Item;\n model.ticket = ticket;\n return View(model);\n }\n\n\nGetTicket() method on the first line returns the session object, here's the implementation:\n\nprivate Ticket GetTicket()\n {\n Ticket ticket = (Ticket)Session[\"Ticket\"];\n if (ticket == null)\n {\n ticket = new Ticket();\n Session[\"Ticket\"] = ticket;\n }\n return ticket;\n }\n\n\nNow heres the view that takes the model and enables some edit fields for the ticket:\n\n@model WebUI.Controllers.TicketCreationModel\n\n\n@{\nViewBag.Title = \"AssignSupportItem\";\n}\n\n<h2>AssignSupportItem</h2>\n\n\n@using (Html.BeginForm()) {\n @Html.ValidationSummary(true)\n\n<fieldset>\n <legend>Creación ticket</legend>\n\n <label>Descripción del problema</label>\n <div class=\"editor-field\">\n @Html.EditorFor(model => model.ticket.Description)\n @Html.ValidationMessageFor(model => model.ticket.Description)\n </div>\n\n @Html.HiddenFor(model => model.ticket.TicketId)\n @Html.HiddenFor(model => model.item)\n @Html.HiddenFor(model => model.employee)\n\n <label>Solución aportada</label>\n <div class=\"editor-field\">\n @Html.EditorFor(model => model.ticket.Solution)\n @Html.ValidationMessageFor(model => model.ticket.Solution)\n </div>\n\n <label>Estado</label>\n <div class=\"editor-field\">\n @Html.EditorFor(model => model.ticket.Status)\n @Html.ValidationMessageFor(model => model.ticket.Status)\n </div>\n\n <p>\n <input type=\"submit\" value=\"Save\" />\n </p>\n</fieldset>\n}\n\n\n\n@section Scripts {\n @Scripts.Render(\"~/bundles/jqueryval\")\n}\n\n\nAnd finally heres the method called by the form on the view which recieves the model object:\n\n[HttpPost]\n public ActionResult AssignSupportItem(TicketCreationModel model)\n {\n\n Ticket final = model.ticket;\n final.Item = GetTicket().Item;\n final.AccountableEmployee = GetTicket().AccountableEmployee;\n\n repo.SaveTicket(final);\n ViewBag.Message = \"Su ticket ha sido agregado al sistema\";\n return View(\"AssignSupportItemResponse\");\n\n }\n\n\nThe problem is that the model object i receive has the employee and item attributes as null, why is this happenning? I'm sending those objects on my model why are they getting lost? I tried to restore them with the session object but as soon as I try to persis the object on my context class i get \n\n“An entity object cannot be referenced by multiple instances of IEntityChangeTracker”\n\nexception.\n\nAny help will be appreciated, thanks in advance."
