I'm coding a tip calculator in TI Basic for a TI 84 Plus Silver Edition calculator. The code is as follows:
:ClrHome
:DISP "TIP CALCULATOR"
:Input "COST:", M
:M*0.15->Y
:Disp "15 PRCT:"
:Output (3, 12, Y)
:M*0.20->Z
:Disp "20 PRCT:"
:Output (4, 12, Z)
:M*0.25->X
:Disp "25 PRCT:"
:Output (5, 12, X)
:M*0.33->W
:Disp "33 PRCT:"
:Output (6, 12, W)
However, when I run this program, two things happen I don't want to happen. If I'm on just "Float" on the mode, all numbers goes to three digits (ie 3.829 for a 15% tip on 25.53). Also the last number runs 4 digits, so it's breaking onto the "Done" line. I'm aware if I change Float to 2 in the "Mode" menu, this solves both problems. However, it is tedious to change this back and forth just to run this program. I asked ChatGPT and it told me to use "toString(int", but this isn't available on the TI 84 Plus Silver Edition. Any help?

I'm about to upgrade from an AMD GPU to an NVIDIA one, not for gaming, but for the sake of AI ML and video editing. Will there be any driver issues (including with DirectML, GPUOpen, or OpenCL), so that I'll need to de-install those? 2003:DA:CF11:CF56:691A:42A:6552:8061 ( talk) 19:53, 17 July 2024 (UTC)

Hopefully @ PantheraLeo1359531: doesn't mind but I saw they posted a question on Commons that I thought the Reference desk detectives may like to look at...
Mysterious Intel microprocessor/IC:
I recently bought 2 Intel processors (I couldn't resist, as they look so similar to the famous Intel 4004), but I don't know what the purpose could be. Looking at the ceramic package, I can imagine that the product was created maybe between 1972 and 1975. Maybe someone can give a hint?
If you know the answer you can reply here and I will relay to Commons. Commander Keane ( talk) 00:17, 18 July 2024 (UTC)
Just earlier today, while I was at university, I stumbled upon a "This IP address is blocked from editing Wikipedia" banner when I clicked on the edit button of a Wikipedia article to check out some source code. I was like fine, there are thousands of users on this network and so quite inevitable someone's gonna do something bad leading to IP addresses / ranges being blocked from editing. All until I spotted something very odd regarding the IP range that is blocked, compared to the current IP address.
It said, the blocked IP address or range is 122.56.x.x/20, but then it also said, your current IP address is 202.36.x.x. I know quite a bit about subnets and how IPv4 addresses are divided up, so something just didn't seem right to me here! On a /16 to /23 IPv4 range, the left two groups of digits never change. 202.36.x.x is obviously not part of 122.56.x.x/20. I was thinking, how is this possible?!?
If I clicked on the "Talk" or "Contributions" buttons in the upper-right corner, indeed I would get the 202.36.x.x IP address and not one in the 122.56.x.x/20 range. Looking at the IP's contributions, there were like only a dozen or so edits, quite a few from 2019, but absolutely no edits from 2020-2023, and one edit in 2024. The talk page had this shared IP address banner at the top saying that it is registered to the University of Auckland.
According to WHOIS info, the 122.56.x.x/20 subnet is registered to a well-known large ISP for educational institutions here in New Zealand, and the 202.36.x.x IP address is registered under the name of the university itself, with even stuff like the building location address being of the university.
My guess is that the 202.36.* network is actually the university's own "private ISP" kind of network, used for communication between the different campus buildings, while the 122.56.* network is the public ISP that the university network is connected to and is using for internet.
Does anyone else know what's going on here? Man, this issue definitely explains a lot of those IP address unblock requests where the user claims that their IP address is never blocked but they are somehow unable to edit, getting a blocked from editing message. — AP 499D25 (talk) 10:19, 18 July 2024 (UTC)
I am trying to find documentation on the "plan" keyword in Oracle. I am not looking for "explain plan." That is completely different. What I am looking for is the plan keyword in this context:
select a.id from a, b plan a where a.date between begindate and enddate
I have two different Oracle documentation books in PDF. In both if I search for pages with "plan" that do not have "explain", I come up with zero results. Searching the web, I only find explain plan, which has nothing to do with that as far as I can see. 75.136.148.8 ( talk) 20:04, 19 July 2024 (UTC)
I'm curious as to what exactly caused the current CrowdStrike outage. According to this article, [1] the root cause is a single file located in C:\Windows\System32\drivers\CrowdStrike\ and is named C-00000291*.sys. Even though it ends with the sys extension, it is not a kernel driver. I don't have CrowdStrike on my PC and I'm just wondering if this file is a text file, and if so, has anyone compared the broken version with the fixed version and figured out the delta?

I have a Dell Inspiron 3910 with 16 GB of RAM and approximately 216 GB of solid-state storage as the C: drive. I just got a pop-up message saying something to the effect of "We can't back up your system files". It says that if I free up some space on my "hard drive" (which is hard because it is solid-state), it will be able to back up my system files. I don't recall having seen that message before. I do see that I have 10.1 GB free on my solid-state C: drive out of 216 GB. I also see that my pagefile.sys on the C: drive has grown to 26.6 GB, which is what is taking up the space. My question is: What system backup function is there that was trying to back something up, and was unable to back something up? The message was a pop-up, and I can't bring it back, although maybe that isn't important. So: What system process was trying to back something up to my C: drive and didn't have space for the backup? I will, in the very near future, be getting something like WINDIRSTAT to get a better view of how the 206 GB is being used, to see what if anything to move to my F: drive. So what is trying to back up my system files automagically? Robert McClenon ( talk) 18:15, 24 July 2024 (UTC)

If I am using Firefox and Windows 11, and a web site asks me to turn off my ad blocker, and I don't know what ad blocker I am using, how do I determine what ad blocker I am using, so that I can turn it off?
