[Solved] What can I assume for the voltage tolerance of commercial 12 VDC equipment?

Michael Asks: What can I assume for the voltage tolerance of commercial 12 VDC equipment?
I am thinking about 12 V backup power supply options for my home networking equipment; these run from 12 VDC wall warts supplied with the equipment. The data sheets for such equipment typically say nothing about voltage tolerance. They often just say something like, "Use only the power supply that comes with this equipment. Use of any other power supply will void your warranty."

This article reports on tests of a variety of nominal 12V wall warts. Voltage outputs all varied to some extent depending on load. Generally, if the power supply was a linear type, output was 17-12 V (+40% -0% from 12 V), while if a switching type, output was 12.4-11.6 V (+/- 3% from 12 V).

I'll assume, for a start, that if I supply power within +/- 3% of 12 V, I'll be fine with any of equipment. I'm not so sure it would be OK if I hooked up a "12V" lead acid battery, which could be up to 13.8 V.

What is a reasonable limit for the safe tolerance on the voltage to my networking equipment? 5%? 10%? the range of an SLA battery?

I am particularly interested in hearing from 1) anyone who themself has seen a data sheet for networking equipment that does includes a voltage tolerance spec, or 2) someone with experience designing similar commercial equipment and knows what the voltage limits are.

[Solved] Risks of exceeding current discharge rating of a LiPo battery

Jay Asks: Risks of exceeding current discharge rating of a LiPo battery
I have a project that consumes a maximum current of 1.6A, that requires the use of a small LiPo battery. I have one that has the perfect size, but has capacity of 400mA, and a discharge rating of 1C (400mA maximum.) I understand that the internal resistance of a battery is what causes them to heat up under heavy current draw, but would battery thermals be the only risk when drawing 1.6A from a 400mA LiPo battery?

[Solved] How to animate view to custom coordinates in OpenLayers 5?

js1983 Asks: How to animate view to custom coordinates in OpenLayers 5?
Given just a basic ol.Map using OpenLayers 5

Code: 
var map = new ol.Map({ layers: [ new ol.layer.Tile({ source: new ol.source.OSM() }) ] target: 'map' view: new ol.View({ center: [0,0], zoom: 2 }) });

I am attempting to allow for a user to enter a lat/lon coordinate in format latitude, longitude in decimal degrees. I want to create an event that animates the map to move to that entered coordinate.

Code: 
var panToPosition = function (latlon) { if (/^(\-?[0-9]{1,3}\.?[0-9]{0,10}\s{0,10}\,\s{0,10}\-?[0-9]{1,3}\.?[0-9]{0,10})$/.test(latlon)) { var arrLatLon = latlon.split(','); var latitude = arrLatLon[0]; var longitude = arrLatLon[1]; var coords = [parseFloat(longitude), parseFloat(latitude)]; Ext.GeoSpatialSearch.map.getView().animate({center: coords}); } };

When this function fires, the map animates, but it always goes to [0,0], not the coordinate array I have selected.

I have found this example on another site

Code: 
var coords = fromLonLat([parseFloat(latLong[1]), parseFloat(latLong[0])]);

but it is unusable as fromLonLat is not a usable function in OpenLayers 5, only 6+. Why is it always going to 0,0 instead of the given coordinates? If I do need to transform to a different projection, how do I do so?

Mohammad ElNesr Asks: Missing the raster interpolation plugin in QGIS 3
I can't find the Raster ‣ Interpolation plugin in QGIS 3, I tried to search for it through the plugin's installation applet following this tutorial and searched for 'interpolation', but it doesn't appear! I searched for it in the Processing Toolbox, but no luck as well!

Has it been deprecated? or what am I making wrong?

I have QGIS 3.24.1Tisler

[Solved] Append Data to Feature Service in AGOL

John Van Hoesen Asks: Append Data to Feature Service in AGOL
I have a Feature Service published out of Fulcrum App (see info here) that contains points, an underlying attribute table, and images at each location. I am wondering about approaches for appending this data to a separate feature service hosted in an ArcGIS Online editable app. The Batch Editor widget works, but it's unclear how to migrate the images.

Do I 'have' to download to a GDB and then upload, can this happen directly in ArcGISPro, etc?

[Solved] Why my Wordpress website homepage automatically adding cs_preview=true query parameter to the url?

Shuvam Shah Asks: Why my Wordpress website homepage automatically adding cs_preview=true query parameter to the url?
I took a help from freelancer to build a Wordpress website. Now whenever I go to the homepage at <website-name>.com it automatically redirects to <website-name>.com/cs_preview=true. I checked the dashboard and the permalink of the homepage is without this query parameter. How to remove this so that it looks more professional?

[Solved] No page numbering is appearing when using fancy header and subfile packages?

Rocky the Owl Asks: No page numbering is appearing when using fancy header and subfile packages?
I know this topic is the subject of numerous posts on this forum. I have read through them, but I don't really understand the answers and they haven't been working for me. Furthermore, I am also using the subfile package, so I am not sure if that complicates matters.

Please note, I am set on using subfiles and I have previously made all the page numbering work, but I no longer have access to that code so I cannot quite find what I need to do.

Example:

Here is a quick example that I just made up: (to be run in Overleaf). I know there are lots of redundant packages, but I have just left them all in so I don't need to worry about issues appearing when I add them back in...

Code: 
\documentclass[11pt,a4paper]{article} \usepackage[utf8]{inputenc} % set font \usepackage{fontspec} \setsansfont{Arial} \renewcommand{\familydefault}{\sfdefault} %overrides automatic normalFont from \begin{document} % setting the line spacing \usepackage{setspace} % set margins \usepackage[a4paper, margin = 20mm]{geometry} % sets all margins to 20mm % for figures \usepackage{graphicx} \usepackage{wrapfig} \usepackage{caption} \usepackage{subcaption} \usepackage{rotating} \captionsetup{font=small} \captionsetup[figure]{labelfont=bf} %,textfont=it} \captionsetup[table]{labelfont=bf} % for tables \usepackage{booktabs} \usepackage{longtable} \usepackage{enumitem} \usepackage{blindtext} % for paragraphs \setlength{\parindent}{0pt} \usepackage{parskip} %\setlength{\parskip}{0.8em} % to get degree symbol \usepackage{textcomp} % for arrows and therefore \usepackage{amssymb} \usepackage{amsmath} \usepackage{bm} % to exclude subsubsections from ToC %\setcounter{tocdepth}{2} % for cross referencing files \usepackage{comment} \usepackage{multicol} \usepackage{multirow} \usepackage{makecell} % allow multilines in tables \usepackage[table,xcdraw]{xcolor} \usepackage{xr} \usepackage{float} \usepackage{fancyhdr} \usepackage{afterpage} %\renewcommand{\headrulewidth}{0pt} \renewcommand{\footrulewidth}{0pt} \fancyhf{} \pagestyle{fancy} \usepackage{hyperref} \usepackage{cleveref} % load this last \usepackage{subfiles} \begin{document} \pagenumbering{gobble} \numberwithin{equation}{section} \numberwithin{figure}{section} \numberwithin{table}{section} \begin{titlepage} \begin{center} \vspace*{4cm} \begin{center} \Large \textbf{TITLES} \end{center} \vspace{1cm} RANDOM TITLE WORDS HERE \vspace{1.5cm} \textbf{AUTHOR NAME HERE} \vfill COLLEGE REPORT TESTER \\ \end{center} \end{titlepage} \singlespacing \thispagestyle{empty} % to remove the line from ToC pg. 1 \tableofcontents %\thispagestyle{empty} % to remove the line from ToC pg. 2 \pagenumbering{arabic} \thispagestyle{fancy} \doublespacing \cleardoublepage \setcounter{page}{1} % start page count at 1 instead of 2 \subfile{Abstract} \clearpage \newpage \subfile{TESTER} \end{document}

In the 'Abstract.tex' file, I have the following code:

Code: 
\documentclass[./main.tex]{subfiles} \pagestyle{fancy} %\chead{} \cfoot{\thepage} \begin{document} \section{Abstract} \blindtext \end{document}

and in the 'TESTER.tex' file I have:

Code: 
\documentclass[./main.tex]{subfiles} \pagestyle{fancy} %\chead{} \cfoot{\thepage} \begin{document} \Blinddocument \end{document}

However, there are no page numbers appearing at the bottom of the pages. The table of contents is able to detect the page numbers correctly, but I cannot understand why they won't appear.

Any help is greatly appreciated as I have spent a decent amount of time trying to fix this to no avail.

[Solved] Remove or re-index content for DuckDuckGo?

mbomb007 Asks: Remove or re-index content for DuckDuckGo?
Google has the "remove outdated content tool" to prompt it to rescan outdated content on a site you don't own. I have some content that I changed, and I would similarly like DuckDuckGo to re-index or remove the content.

The old content is in the index and has been outdated for a while. Is there a way to prompt DuckDuckGo to re-index/remove similar to how Google works?
