G'day mate. Windows 11 Home 22H2 build 22621.2134

There are several free libraries available for calculating with big numbers in c. Google c bignum library to see a few.

Try going into

Personalization -> Lock Screen

Select some option other than Windows Spotlight, exit, and reboot. Then go set it back to Windows Spotlight.

My laptop seldom leaves my house. When I am not using it I close the lid to put it into sleep mode. I also close the lid when carrying it to another room (or perhaps into the backyard hammock). This causes a minor inconvenience as every time I open the lid I have to enter my password to unlock it. On my old (Windows 10) laptop I was able to turn this off but because Microsoft keeps changing the layout of the Settings app I had to Goggle to find out how to disable this in Windows 11. The new process was

1. Open Settings
2. Select Accounts
3. Select Sign-in options
4. Scroll down to Additional settings

Under Additional settings there is a section with the text If you've been away when should Windows require you to sign in again?" To the right of this is a drop-down box with the default text Every Time. According to Google (and Microsoft) I simply have to select a different option, like Never**.

That would be the case if the entire section were not greyed out and followed by the text Windows Hello is preventing some options from being displayed.

The recommended solution from Microsoft was to

1. Install the latest version of Windows
2. Apply all outstanding Windows updates
3. Run the Surface Diagnostic Toolkit
4. Run the built-in troubleshooter
5. Remove Windows Hello and re-install it

Since I keep my laptop current I focused on Windows Hello. Specifically, Windows Hello is used to facilitate access …

Welcome to Daniweb. I hope this leads to many interesting discussions.

Welcome to Daniweb

A programmer (or programmers) going by the alias Nea Paw has created an AI application called CounterCloud that automatically generates responses to Russian and Chinese disinformation posts/tweets. We have now entered the era when information/disinformation generated by bots will flood the internet and we will be unable to wade through the BS to determine what is reliable and what is not.

Sort of like now, except exponentially worse.

What skills are you planning to work on?

I don't have a brother in Syria, let alone one with a laptop, let alone a brother.

Been a while since I thought of something to add...

I hate the trend these days of showing text messages on a character's phone. These are impossible to read from across the room, even on a big screen TV. In order to keep up with the show I have to keep pausing and walking across the room. In the Cumberbatch/Freeman version of Sherlock, however, instead of showing the screen, they'd show pop-ups of the messages in letters large enough to read. So it can be done correctly. It just mostly isn't.

I admit I am ignorant of anything to do with Apple products, other than that they seem to keep removing features that people like.

I'd hate to think you were one errant baseball (or hockey puck) away from losing access. What if you were in a car accident and got your face pounded by the air bag? Would you be unable to unlock your phone to call 911?

Interesting AI article

From what I gather, no, because all the "creation" was done by you.

if I prompt an AI platform to write something, then the AI platform generates something, and may even add it to its own database before even showing it to me. At that point, by the time I've seen it for the first time, it's been created by another entity and stored in that entity's database.

If you use an IDE that supports code snippets, by inserting a code snippet are you giving up any of your intellectual property rights to the people who created the IDE and supplied the code snippet library?

What does existing copyright law say today about me handing a photography expert an old photo, and that expert manually colorizing and enhancing the photo with their own skillset?

I have no idea.

This is similar to how an author, by default, is also the owner of the copyright.

There is a fair use doctrine (I think that is the name) that protects people who do things like use quotes from known works, or who parody the works of others. I'm not sure exactly how this works since I have heard that Weird Al cannot parody songs without the permission of the original artist. If fair doctrine applies to code, how much code would I be able to "borrow"? If I copy/paste a code snippet from the web, am I violating copyright?

I'm asking out of curiosity since I have no intention of ever asking for payment for anything I write.

When I joined in 2010 I thought there was a clause in the TOS that said Dani owned the rights to any software posted on the site. It's possible (gasp) that I am mistaken, or that the TOS has been modified since then. In any case, I gave up my desire to be paid for code when I retired and as far as I am concerned she is welcome to anything I post.

Having said that, given the capabilities of modern IDEs, changing variable names, etc. is trivial so it would be difficult to prove that the modified code is a rip-off of the unmodified code, at least for interpreted code like Python. I would imagine it would be much more difficult for compiled code.

Where do you draw the line? If I set up parameters for ray-tracing and run them through "generative" software, would I own the rights to the result? Pre AI I believe I would have, but now it could be argued that I would not. Consider a tool like Topaz Photo AI. Would it be possible that I could own the rights to a blurry photo (input) but not the enhanced output? Would it depend on the amount on enhancement?

My problem was with the "negativity bias" statement although I suppose you could make a case based on evolution. If you pay more attention to negative news than positive news you are less likely to ignore potentially dangerous stimuli (is the rustling bush a predator or the wind).

I don't entirely agree with that. I think the reason bad news prevails is

1. It produces a stronger emotional response
2. It requires almost zero thought
3. There is just so much more of it

I can believe the negativity bias in the case where it confirms (or seems to confirm) something you already believe.

That's a problem when the news shows only allocate two minutes to cover the topic. You need much more than that to cover it fairly. And, honestly, most people would just tune it out (the same people who read only the headlines). The only person I trust to give it a fair hearing is John Oliver. If you ignore the crude asides, he does cover his main stories in great detail.

It's hard to offer a solution when you haven't described the problem other than "stopped working". What has changed since it "was working"?

Another area is to contract for code that used regular expressions

Ooooh. I had not thought of that one. That would be awesome. At least it would be if more people knew how to properly express their wishes in plain English.

exp = rx.compile("It's like, you know a letter or whatever followed by a dot and some stuff, right?")

My problem with IoT and mobile devices is that every device needs its own app, and every app has its own unique interface. And how many of those apps come with ads? I had a friend a few years back who had physical remote controls for

1. TV
2. Stereo
3. CD Player
4. Overhead fan
5. Electric fireplace

and maybe one or two more I've forgotten. The coffee table was littered with remotes, and it was always a nuisance looking for a specific remote. Far easier to just walk across the room. At least in that case the interfaces were essentially the same - a few clearly labeled buttons (no scrolling necessary). Now you have to unlock your phone (swipe/scroll), locate the appropriate app (swipe/scroll), wait for it to connect (depends on the reliability of your Bluetooth and possible interference from your microwave oven and other devices), then navigate to the appropriate controls.

And this all depends on whether or not you have updates pending.

And, seriously, how many of our devices really need to be connected? Just because something is technologically possible does not mean it is preferable. In the 90s we had the "dot com" bubble. Adding ".com" to your company name gave it a big boost on the stock market. Then we got the same artificial bump by adding the magic word "blockchain". Now we have cryptocurrency and IoT. As long as our educational system keeps pumping out people incapable of critical thinking we will continue this trend.

I don’t see the positive in that.

I suppose that depends on whether it is good code, or bad code.

The main purpose of ANY testing is to identify and eliminate

1. bugs
2. bad/inefficient/confusing user interfaces

I really don't know why the question even needed to be asked.

Why is there air? There's air to blow up footballs and basketballs. - former (now disgraced) stand-up comic

The link is broken. Please post the code and the error message.

First of all, please, please, please learn to

1. add whitespace
2. add comments
3. break up monolithic code into logical segments
4. pick meaningful variable names (or at least document them)

Rather than debugging your code I'll give you an example of blitting a semi-transparent circle

import pygame

pygame.init()

width, height = 800, 600
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption('Semi-transparent Circle')

circle = pygame.Surface((100, 100), pygame.SRCALPHA)
colour = (0, 0, 0, 128)
centre = (50, 50)
radius = 40

pygame.draw.circle(circle, colour, centre, radius)

running = True

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.fill((255, 255, 255))
    screen.blit(circle, (width // 2 - 50, height // 2 - 50))
    pygame.display.update()

pygame.quit()

You wouldn't expect to get ripped by getting someone else to go to the gym for you. You won't learn how to program by getting someone else to do your homework.

But if you are having a particular problem, please post your code and an explanation of the problem and perhaps we can offer some help.

Got a link for that?

It's still happening to me as well and the usual fixes (sfc, dism) have found/fixed nothing. At least with VLC I can set it to be always on top.

So, technically, a Brazil nut.

Sorry.

Welcome to Daniweb.

Can you please define what that is and why we should care about it?

A subtle difference, but it makes sense.

When I had a bad lower back injury years ago I built a kneeling chair that was very comfortable for working. It looked very similar to this one except I built mine for under $10.

Please note I am in no way promoting/endorsing the product in the link.

I came across this item while programming something that should have been very simple. VLC Media Player will save the last viewed position in a media file (assuming you have the resume option enabled). It maintains two lists, file names, and offset times. The file names are encoded such that certain characters are replaced with "%" strings (%20 for a blank, for example). I wrote a short script to remove the resume entries for files that were no longer on my computer.

The Python urllib has two handy methods for encoding/decoding these strings within URLs. In my code I had

import urllib
.
.
.
file = urllib.parse.unquote(file_list[i])

I developed the code using idlex (an idle variant). Once the code was debugged I attached it to a hotkey. Much to my surprise, running the code with the hotkey did nothing. Stripping it down to the bare essentials gave me

import urllib

print(urllib.parse.unquote('my%20file.txt'))

Running it from within idlex resulted in

======================= RESTART: D:\temp\test.py =======================
my file.txt

but running it from a cmd shell gave me

Traceback (most recent call last):
  File "D:\temp\test.py", line 3, in <module>
    print(urllib.parse.unquote('my%20file.txt'))
AttributeError: module 'urllib' has no attribute 'parse'

From the idlex shell, typing dir(urllib) gives

>>> dir(urllib)
['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', 'parse']

and running the same from Python invoked in a cmd shell gives

>>> dir(urllib)
['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__']

The idlex environment adds parse. I found the same addition when I edited and ran …

Unfortunately, also without providing security and privacy.

As the message says, strings do not have a "reverse" attribute (method or property). You can reverse a string by

newstring = my_string[::-1]

If you run idle or idlex and start a shell (interactive) window you can see your options by assigning a string to "my_string", then typing "my_string" followed by a dot, and then waiting for the intellisense pop up.

I couldn't believe 4.5 hours to do an update (from the posted article). My updates download in the background so I don't know how long that takes, but the install/restarts take five minutes at the most.

That looks promising. Incidentally, Daniweb shows that as a broken link, but if I click on it and select "go there anyway" it takes me to the page. Curious. I've seen this happen here before recently.

On line 10 you have count+=1:. Python will tell you that this is a syntax error. Take off the trailing colon. However this still leaves you with a problem. The game runs, but it does not display the hangman in progress when you guess a wrong letter.

I've only ever noticed this happening while playing a video in vlc media player. I'll have the video playing in full screen with the video's folder in the background. Without touching the mouse, keyboard, or touchpad, the background Explorer window will pop to the front, obscuring the video. I can have other apps open, but it's always an Explorer window that pops up.

Or the way they slapped "User Friendly" on the outside of the box without actually making the software user friendly.

I can't help you with blockchain, but I am curious as to the part of your post where you say

By framing the question in this way, you're indicating that you're seeking guidance and open to different programming languages and approaches, which can encourage members of the forum to provide their insights and code examples.

I'm reminded of a scene in MTM where Ted Baxter (reading the news off the cue cards) says out loud "take off glasses and look concerned."

I forgot one point. Social media platforms are a tool that big business uses to harvest your personal data for profit. If the government was asking for the same data we'd be screaming about "Big Brother", but it seems most people are happy to just give it away to Google, Facebook, etc. Remember what they say, "if you aren't paying for it then YOU are the product".

In my opinion the major purpose of social media platforms is to provide people with no voice a platform. Unfortunately that platform is used mainly to shout "HEY EVERYBODY LOOK AT ME LOOK AT ME LOOK AT ME". In other words, social media is mostly a vast wasteland.

Elon Musk recently put a cap of 600 for the number of tweets that can be read by a user per day. After (supposedly) widespread outrage he relaxed this to 800. If you find 600-800 a limit then you are spending way too much time on social media. Go read something worthwhile.

I wrote a timer/alarm app in Python that I wanted to be accessible from all Windows Desktops. What I had to do until recently was run the app, select the desktops icon on my toolbar, then right click the app and select "Show this window on all desktops". I was certain there was a way I could do it from within the app and after a little research I found it. Here is a function you can call to do this. Note the usually bad practice of using an except clause to trap all possible errors.

Python in an excellent first language to learn. It has low overhead (you don't need a lot of boilerplate code for simple programs) and a structure that promotes clear, readable code. The IDE that comes with it (Idle) can be learned in a few minutes, and the included REPL (Python shell) allows for easy experimentation.

There are tons of available free online tutorials and help. Plus piles and piles of source code examples and high quality packages for just about every application.

There are two types of people - those who divide things into two types, and those who don't.

I am so sorry to hear that. Concentrate on getting better and we'll keep an eye on things here.
