So in order to add a new website to track, you go to Admin at the top and look at the Property column in the middle ().

| My old laptop computer developed problems with the power, so that it wouldn't start when connected to regular line current. It would start when connected to high-amperage current in an electronics store, but that wasn't useful, and it was time to replace it after five years. I now have some questions about problems with a new laptop computer. The new laptop computer is an HP running Windows 11. ] (]) 04:43, 15 December 2024 (UTC) | |||
| ===Cursor Jumping Randomly=== | |||
| Sometimes when I am typing in a Word document or editing Misplaced Pages in a source window, I discover that the cursor isn't where I think it should be. The cursor has jumped to somewhere else on the screen, apparently randomly. I have to do a Ctrl-Z to undo what I typed in the wrong place, and then move the cursor back to where I want it. If this is caused by line noise, how do I minimize the impact? How likely is that a new mouse would resolve the problem? Are there any settings that I should diddle with? | |||
| ] (]) 04:43, 15 December 2024 (UTC) | |||
| :First thing I would do is give the mouse and mousepad a good clean and disconnect and reconnect it. ]|] 09:14, 15 December 2024 (UTC) | |||
| :::Generally this is impossible. There is no central registry of key combinations in Windows. Instead, each program is notified when the keyboard state changes. To figure out which key combinations it responds to, you have to reverse-engineer the code. The best an automated tool could do would be to recognize certain common ways of handling shortcut keys (for example, accelerator resources in Win32 programs), but it would miss a lot. -- ] (]) 19:36, 6 July 2016 (UTC) | |||

| :::I now have a possibly useless question. The documentation referred to an option that disables the touchpad when there is a mouse, but the only option that I found in the settings is the option that always disables the touchpad. I would like to specify that the touchpad is disabled when there is a mouse, and enable it if there is no mouse. This makes very little difference because I will always use a mouse. Is it possible that that option isn't available on my computer? This isn't important. ] (]) 02:38, 17 December 2024 (UTC) | |||
| ::::Possibly true, your system vendor might not have put any software on there to do that automatically. The general rule with computers is, you can make it do what you want, it's just a question of how much effort is involved in that.

Here's an answer for how to run a script when a device is connected: , if you really want to put in the effort.

| With the old laptop, I had set up network file sharing, so that the laptop computer could view and edit files in shared folders on my desktop computer, a Dell, also running Windows 11, if they were both within range of my wireless router (and the desktop computer always is).

I tried calling the technical support offered by the electronics chain that I bought the computers from, and I made seven calls to them, none of which worked, and I have concluded that their technical support people don't know what they are doing, and, worse, don't know the limits of their knowledge. Does anyone have advice on a book that will tell me how to set up network file sharing with Windows 11, that has neither too little nor too much information for a retired database engineer? | |||

As the x64 CPUs are stil compatible to 32 bit, 32 bit software can be executed un the system, but least 4 GB RAM, only.

| :Not with one measurement. You need to measure the current, disconnect the multimeter, reconnect the supply, then measure the voltage. ] (]) 09:29, 9 July 2016 (UTC) | |||
| :Incidentally, if you have a simple arrangement with a resistor in series with the LED, you can measure the current by measuring the voltage across the resistor, and using the equation <math>I = {V \over R}</math>. You still need to make a second measurement of the voltage across the LED, though. ] (]) 09:41, 9 July 2016 (UTC) | |||
| ::Many thanks Tevildo. If it's not taking too much advantage of your generosity, I'd beg you to be a bit more elaborate. For instance in first instruction you say "measure the current", now shall I measure it along with LED attached or LED removed from the circuit. And is it true that current is never measured like voltage (in parallel) but in series ? As for putting resistor in series with LED that ain't difficult, why not simply jump to this step ? Please tell how voltage across resistor and across LED ultimately give us wattage. Unless I am very much wrong I think current and wattage are separate things. ] (]) 17:00, 9 July 2016 (UTC) | |||

| :::No problem, it's what we're here for. I'm assuming your circuit is basically the same as the one to the right (from our ] article, with annotations). To find the power, we need to find the voltage across the LED and the current through it, and multiply them together. | |||
| :::Measuring the voltage across the LED is easy: | |||
| :::*Set your multimeter to "DC Volts". | |||
| :::*Connect the positive lead to point B on the diagram, and the negative lead to point C. | |||
| :::*The reading on the multimeter is the voltage across the LED. Let's call this <math>V_{LED}</math>. For example, it might be 3 volts. | |||
| :::There are two ways to measure the current. The first is to measure it directly with the multimeter: | |||
| :::*Disconnect the wire between the power source and the LED (between points A and B on the diagram). | |||
| :::*Set your multimeter to "DC Amps". | |||
| :::*Connect the multimeter positive lead to point A on the diagram (the supply positive output), and the negative lead to point B (the LED anode). | |||
| :::*The LED should now be on. The reading on the multimeter is the current in the LED. Let's call this <math>I</math>, as in the diagram. | |||
| :::The second way is to measure the voltage across the resistor. This assumes you know what its resistance is. | |||
| :::*The circuit should be connected as in the diagram (with the LED on). | |||
| :::*Set the multimeter to "DC Volts". | |||
| :::*Connect the positive lead to point C, and the negative lead to point D. | |||
| :::*The reading on the multimeter is the voltage across the resistor. Let's call this <math>V_R</math>. | |||
| :::*If the resistance of the resistor is <math>R</math>, the current in the LED is <math>V_R \over R</math>. For example, if <math>R</math> is 100 ohms, and <math>V_R</math> is 2 volts, the current (<math>I</math>) is 20 mA (0.02 = 2 / 100). | |||
| :::Now we know <math>V_{LED}</math> and <math>I</math>, the power of the LED (in watts) is <math>W = I \times V_{LED}</math>. Using the numbers from above, the power is 20 mA * 3 V = 60 mW. Hope this helps! ] (]) 18:08, 9 July 2016 (UTC) | |||
| :I suggest you get a device like the ] meter, which does the math for you and lists the wattage directly: . ] (]) 17:08, 9 July 2016 (UTC) | |||
| ::This is for mains equipment, and the OP just wants to measure the power for a (DC) LED. ] (]) 18:08, 9 July 2016 (UTC) | |||
| :::To be more specific, if you try to measure the ]s of an ] circuit by measuring ]s and ]s separately and calculating the result, you end up with ]s, not watts. In ] circuits watts and volt-amperes are identical, so the technique works. The math is easy: volts times amperes equals watts, as Tevildo explained in detail above. --] (]) 22:09, 9 July 2016 (UTC) | |||

| :::One obvious factor is cost. The best technology to replace these old technologies, as far as readability, is likely a black-and-white ] (color seems like an unnecessary expense). I imagine they cost more initially (but maybe not by much, if it only prints the width of a receipt or airline ticket). However, for these high volume operations, the more important issue is what it costs per print. Can anyone provide data on this, for dot-matrix, thermal, and black-and-white laser printers ? ] (]) 15:13, 10 July 2016 (UTC) | |||

Questions About New Laptop Computer
My old laptop computer developed problems with the power, so that it wouldn't start when connected to regular line current. It would start when connected to high-amperage current in an electronics store, but that wasn't useful, and it was time to replace it after five years. I now have some questions about problems with a new laptop computer. The new laptop computer is an HP running Windows 11. Robert McClenon (talk) 04:43, 15 December 2024 (UTC)
Cursor Jumping Randomly
Sometimes when I am typing in a Word document or editing Misplaced Pages in a source window, I discover that the cursor isn't where I think it should be. The cursor has jumped to somewhere else on the screen, apparently randomly. I have to do a Ctrl-Z to undo what I typed in the wrong place, and then move the cursor back to where I want it. If this is caused by line noise, how do I minimize the impact? How likely is that a new mouse would resolve the problem? Are there any settings that I should diddle with? Robert McClenon (talk) 04:43, 15 December 2024 (UTC)
- First thing I would do is give the mouse and mousepad a good clean and disconnect and reconnect it. Shantavira| 09:14, 15 December 2024 (UTC)
- Possibly due to your hand brushing the trackpad while typing. If you have a mouse, you could experiment with disabling the trackpad: how to disable touchpad on hp laptop. Or even just try turning it off while typing. This erratic caret jumping used to happen to me a lot, too, when my laptop was new, until I found the key to disable the trackpad.
- The term caret or insertion point is useful to exclude the mouse cursor (the pointer) from searches. Card Zero (talk) 12:54, 15 December 2024 (UTC)
- Thank you, User:Card Zero. I disabled the touchpad. For users who always use a mouse, the touchpad is a complication. Robert McClenon (talk) 19:06, 15 December 2024 (UTC)
- I now have a possibly useless question. The documentation referred to an option that disables the touchpad when there is a mouse, but the only option that I found in the settings is the option that always disables the touchpad. I would like to specify that the touchpad is disabled when there is a mouse, and enable it if there is no mouse. This makes very little difference because I will always use a mouse. Is it possible that that option isn't available on my computer? This isn't important. Robert McClenon (talk) 02:38, 17 December 2024 (UTC)
- Possibly true, your system vendor might not have put any software on there to do that automatically. The general rule with computers is, you can make it do what you want, it's just a question of how much effort is involved in that. To do stuff automatically when hardware is (dis)connected, you have to set up something that subscribes to WMI events: Windows's thing for letting all interested parties know "hey some new device just showed up". Here's an answer for how to run a script when a device is connected: , if you really want to put in the effort. Alternatively if you just want something quicker and simpler but not automatic, you can install AutoHotkey (quite useful program) and set a shortcut key on the keyboard to disable/enable touchpad. --Slowking Man (talk) 19:11, 26 December 2024 (UTC)

Network File Sharing
With the old laptop, I had set up network file sharing, so that the laptop computer could view and edit files in shared folders on my desktop computer, a Dell, also running Windows 11, if they were both within range of my wireless router (and the desktop computer always is). The desktop computer could also access files in shared folders on the laptop, if the laptop was I have tried to set up network file sharing with the new laptop computer. I tried calling the technical support offered by the electronics chain that I bought the computers from, and I made seven calls to them, none of which worked, and I have concluded that their technical support people don't know what they are doing, and, worse, don't know the limits of their knowledge. Does anyone have advice on a book that will tell me how to set up network file sharing with Windows 11, that has neither too little nor too much information for a retired database engineer? Robert McClenon (talk) 04:43, 15 December 2024 (UTC)
- @Robert McClenon Did you try this? TheTechie@enwiki (she/they | talk) 20:21, 16 December 2024 (UTC)
- User:TheTechie - Thank you. That describes the basics, and describes what I had done successfully with the previous laptop computer. I need either a much greater level of detail, or a troubleshooting guide, or something like that. That was helpful in that it doesn't point out anything that I am doing wrong. Robert McClenon (talk) 02:31, 17 December 2024 (UTC)
- Asking for clarification: you did all the steps in the section "How do I troubleshoot sharing files and folders" on that page, on the new laptop? After doing those steps, you still don't "see" your desktop in File Explorer on laptop? (Restart the laptop just in case.) Slowking Man (talk) 04:24, 26 December 2024 (UTC)

- Check that all the computers are on the same network. See if all the IP addresses are different. See if the wifi has the network profile set to Private. See if file explorer shows it in Network, or \\newlaptopname . You may have to check file wall settings Graeme Bartlett (talk) 07:29, 26 December 2024 (UTC)

Scanning all available streams
Hello there. I'm have a question: How to scan all available online streams from a specified server and port given? For example, I've found a Wowza Streaming Engine server at 115.79.46.164 and port 1935. I want to know which website or software can help me to find all active streams on this server. Thanks for reading. Ccv2020 (talk) 14:22, 16 December 2024 (UTC)
- nmap -- Finlay McWalter··–·Talk 17:02, 16 December 2024 (UTC)
- nmap is just going to let you toss packets to the server and inspect the packets that server decides to send you back in reply. Which is great for networking analysis, but we want to speak application layer here and talk with the "streaming" software on the remote host. Does help at all? (You will need curl if not already installed.) Do take note, the party which owns the server could always have configured it to restrict the information it will give out to the public. --Slowking Man (talk) 19:32, 26 December 2024 (UTC)

I searched for the keywords: "Israel Folau" "Margaret Court" "David Tyree", then Google shows me blank. Is this bug?HarryOrange (talk) 22:35, 24 December 2024 (UTC)
- If I do the same search, this question shows up (twice, due to how the refdesk is organized) plus a link to Stuff. So, it doesn't seem to be a bug. I tried the same format search with much more famous people and got hundreds of links. Matt Deres (talk) 13:20, 25 December 2024 (UTC)

File disambiguators (1): Explorer/W11
Óla! So Explorer adds (n) to a file with a duplicate name to an existing one. Do you have suggestions how to easily identify and delete them? The search option doesn't recognize parentheses, so a search would merely identify files with that number in the title. The reason for asking is that if a folder has a large number of duplicates that should be deleted, it would be easier to sort/select/delete rather than ctrl+click individually.
