Somewhat related to AI watermarking is this recent article in the news. *What does it mean to put a watermark on AI text?* <https://edition.cnn.com/2026/08/20/us/word-of-the-week-ai-watermark-cec> Which references: *How Claude's text watermark works* <https://www.anthropic.com/news/claude-text-watermark> *How AI text watermarking works* <https://declaude.org/watermarking/> Where apparently there is an EU law which requires watermarking... <https://edition.cnn.com/2026/08/11/business/video/invisible-watermarks-comi…> There's also this referenced, but it's behind a paywall. *Technology that can detect text written by AI with 99.9% certainty* <https://www.wsj.com/tech/ai/openai-tool-chatgpt-cheating-writing-135b755a>

Now, turning to your second set of suggestions regarding a more Pythonic coding philosophy and perhaps making use of the db_iter helper: ... It's a good idea where using a generator function to wrap repetitive execute() and fetching patterns certainly keeps code DRY (Don't Repeat Yourself) & I can see the advantage of putting the lookup in the loop. It will take a while for me to fully digest your helpful suggestions, as I noted in the prior response that I suffer from lack of SQL experience. In fact, in the original thread, I originally tried to disassemble the homescreen using SQL queries in DB Browser for SQLite v3.13.1 but gave up. Message-ID: <1165rqh$163h$1(a)nnrp.usenet.blueworldhosting.com> If I were to adapt your db_iter concept while keeping parameterized queries safe, I'd probably modify it to accept a parameters tuple like this: Python def db_iter(conn, cmd, params=(), mapfn=lambda x: x): """Executes cmd with parameters and yields mapped results.""" for item in conn.cursor().execute(cmd, params): yield mapfn(item) That way, I get the clean generator loop style you recommended and maintain strict parameter safety. Thanks again for taking the time to review the code and thank you for offering suggestions such as that refactoring idea.

Hi Lawrence, Thanks for taking a look at the code and for making positive suggestions. I'll take your two sets of suggestions separately, as they're different. 1. Determining the homescreen pane/folder/package hierarchy 3. Stylistically using a more Pythonic coding philosophy I'm only responding to the first item above, as I can't possibly have any qualms with your second suggestion, which is to improve the efficiency. Almost always I aim for the most general solution to any specific problem set, but in this case, the issue is non-root access to protected data. As you noted, python is just about perfect for cross-platform needs, as I'd wager the script likely will work on any platform, including on Android. However, you've no doubt noticed that the Nova Launcher, while originally well acclaimed as the best app launcher on Android, suffered from success in that it was sold (twice!) which is why I use a last known good version. Hence, I agree fully that it would be better to "build" the homescreen layout using anything but a proprietary launcher such as Nova Launcher. If we were simply archiving every single app the user has installed, then we wouldn't need the Nova Launcher layout structure, since it would be trivial to use adb to find all the packages installed & archive the APK(s). But the goal of this thread is to exactly duplicate the exact layout perfectly, so that a perfect migration can occur from one phone to another. a. Every homescreen panel is reproduced b. Every folder in every panel is reproduced c. Every app icon in every folder is reproduced etc. How do we do get a list of panes, folders and app icons inside the folders? At first, I used a FOSS cross-platform SQL browser to parse the SQL data. <https://sqlitebrowser.org/> Where I ditched that methodology early on as I lack SQL query experience. Message-ID: <1164ul5$i$1(a)nnrp.usenet.blueworldhosting.com> Then, I tried the (deprecated but very powerful) adb backup command. adb backup -f novadata.ab -noapk com.teslacoilsw.launcher Where I was pleasantly surprised that allowed access to protected files. Message-ID: <116513t$m0k$1(a)nnrp.usenet.blueworldhosting.com> So one possible general-purpose solution is to craft an adb backup process for each and every app launcher that anyone may use on Android. But, even then, we have to learn how to parse each & every launcher db. As the initial problem is knowing the exact organization of the homescreen. Of course, we can "manually" create the pane/folder/app list & once we do that, we can populate that manual folder hierarchy with the relevant APKs. But how do we obtain the list of panes/folders/packages on any homescreen? The answer to that question, as far as I'm aware anyway, is that every single Android app launcher stores its homescreen structure differently. Worse, much worse, in fact, everything I write is for non-rooted phones. So the app launcher must store that structure in an accessible location. Nova does that. Nova stores the homescreen structure in an SQL database accessible to adb. But how do the myriad other app launchers store the homescreen structure? Samsung One UI Home, Google Pixel Launcher and open-source alternatives each likely store the homescreen structure in their own proprietary way. Worse, for the proprietary launchers, we likely don't have access to that structure without being rooted, which is, for sure, why you suggested we determine the homescreen hierarchy some other way (using Python, perhaps). But how? If we resort to FOSS launchers (e.g., Lawnchair, Librechair, etc.), we probably can solve that problem, but we still have to ask the general user to use one of those launchers, which is likely not better than using Nova. In summary, I can't help but agree fully with your quite reasonable suggestion to generalize the solution so that it works with any launcher. It would be wonderful to build a universal homescreen parser for any launcher, but the security sandboxing of modern Android makes it difficult. Any and all ideas will be considered since your objections are on target. -- We learn best from helpful people who know a hellova lot more than we do.

I need a basic tutorial for GUI creation using Cambalache
by Chris Green Aug. 13, 2026

Aug. 13, 2026

I am a retired software engineer with a background in assembler, C and C++. I now dabble (mostly for my own amusement) in various bits and pieces, mostly in Python nowadays. I have written quite a lot of Python command line programs to run in a terminal. I have also written a couple of simple Python GUI programs using PyGObject and Gtk. This is all on Debian/Linux. I want to go a bit further and it appears that the most obvious next step is to use Cambalache which has taken over from Glade as the default GUI builder for Gnome/GTK. The problem is that there appear to be no tutorials for Cambalache. I can find how to install it (which I had done already without problems) but I can't find anywhere that simply runs through the sequence of actions required to build a working Python GUI using Cambalache. I'm sort of aware that Cambalache creates an XML file that represents the GUI and that XML file has to be processed somehow (by GTKBuilder?) to make a running GUI program. I need a bit more help in understanding the actual process though. Can anyone point me at anything that might help? -- Chris Green ·

re.sub(r'((?<=\A)|(?<=,))(?=,|\Z)', 'NA', ',1,,,two,3,,,') how does it work?
by Veek M Aug. 10, 2026

Aug. 10, 2026

look-ahead look-behind don't consume string so how does it advance through the string - could someone clearly explain how it works. re.sub(r'((?<=\A)|(?<=,))(?=,|\Z)', 'NA', ',1,,,two,3,,,') 'NA,1,NA,NA,two,3,NA,NA,NA' re.sub(r'(?<![^,])(?![^,])', 'NA', ',1,,,two,3,,,') 'NA,1,NA,NA,two,3,NA,NA,NA' My understanding is that there has to be a pattern that consumes the string eg: here [^,] consumes two 3 four and 5 but the look-ahead look- behind eliminate 5 re.findall(r'(?<=,)[^,]+(?=,)', '1,two,3,four,5') ['two', '3', 'four'] If it's matching the empty string '' then why don't we get NA,NA1 etc for ,1
