Where can I find a thesis of recently released Gemini 2.0?

For Gemini 1.5, I find its thesis.

What about recently released Gemini 2.0? HarryOrange (talk) 21:53, 13 December 2024 (UTC)

Here?  --Lambiam 21:55, 14 December 2024 (UTC)

OK That's Gemini 2.0 release information. HarryOrange (talk) 16:52, 15 December 2024 (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 Wikipedia 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|^{feed me} 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: [1], 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 [2] 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)

.kp domains

How many .kp domains are there? Gnu779 (talk) 13:10, 19 December 2024 (UTC)

Did you see .kp#Existing_and_externally_accessible_domain_list? Polygnotus (talk) 19:10, 19 December 2024 (UTC)

https://www.northkoreatech.org/the-north-korean-website-list/ is a bit outdated but has more background info. Polygnotus (talk) 19:20, 19 December 2024 (UTC)

It's ok, bro. I can still view the outdated ones with the Wayback Machine at the Internet Archive. Thanks, Gnu779 (talk) 16:10, 20 December 2024 (UTC)

Is this bug in the google search ?

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)
