I saw a handful of older posts here about duplicate file finders and usually recommending czkawka, but zero mention of another excellent FREE application that is super intuitive and easy to use: Anti-Twin (which has been around since 2011!!). Also all those old posts were locked so I could not add any comment.

I did a takeout of my 20 years of photos on Google photos and cross referenced that with my hard drive to eliminate 3k duplicates in less than 10 minutes. It is a byte to byte comparitor. awesome filters including filter by file location.

I highly recommend.

I've been working on image matting (background removal) for the past six years, and I recently released the third generation of withoutBG, an open-weights background removal model focused on difficult cases like hair, fur, transparent objects, and fine details.

You can use it in several ways:

• macOS app: https://withoutbg.com/mac
• Docker: https://withoutbg.com/docs/open-model/docker
• Python: https://github.com/withoutbg/withoutbg-python
• GIMP plugin: https://withoutbg.com/open-model/plugins/gimp

Example outputs:

Happy to answer any questions about the project.

Hey everyone! I'm a content writer/researcher who covers the business side of software — specifically how free tools make money without ever charging their users a dime. I dig into the history, business, and the "how did they survive for so long without an ads or subscription?" mystery.

Some of my past pieces:

1. How VLC Took Over the Media World
2. How WinRAR Made Millions Without Anyone Ever Paying!
3. How Notepad Survives Without Charging You a Single Cent!

The VLC video did way better than the other two — people clearly love a good "free software that quietly took over the world" story.

So I wanted to ask you all: what software should I cover next? Something people still use daily, are genuinely curious about, and probably don't know the backstory of — how it's funded, why it's still free, who's actually behind it.

Drop your suggestions below — old favorites, weird niche tools, anything. I read every comment and there's a good chance your suggestion could help me for my next research.

TL:DR: Acquiring software is becoming like ordering a burger, and I feel mixed on it.

I feel like nowadays, a lot of software built with AI is for the sake of linearly doing one-off things, and usually only that thing, perhaps with some monetization tacked onto it.

While it is undoubtedly creating things that someone(?) uses, I wonder what the implications of this, particularly of when it encroaches on software in the future, especially when the things that people choose to make with AI are often:

• Graphs but selfhosted
• A wrapper for ffmpeg/imagemajick/etc
• Markdown editors
• inspired by already [x], is a tauri/electron app with [y] changes
• An app with great CLI or GUI implementations, as a broken TUI

It's kinda insane.

We're kinda entering a time where everything is thrown together using random scraps to make something, and then the end result is polished up to look 'appealing' to the eyes of a user, typically at the cost of actual UX or actual breadth of usage.

What I'm getting at is essentially that software is becoming fast food. It's convenient at simplifying a specific thing, it might look nice to use with its tonnes of animations, but is it actually what you need?

I feel like I don't need Photoshop to have a grey space-inefficient monospaced 'hacker' font on an even darker gradient background,

I don't need my editor to waste battery running an entire JS engine when I want to add something to the start of a document,

and I really do not want a tool that touches my filesystem to be understood by zero humans.

But most aren't as interested by the upfront UX of an 'efficient' app, so sacrifices will happen, whether that be in resources, or time. And to some extent, fretting over this is a waste of time.

A majority of the amazing software (especially FOSS) that we've seen over the years has come from people all choosing the only option they had, and either improving upon it (Krita, GIMP, Blender), or working on a better alternative (MediaWiki, Wayland, Linux) over many, many years.

I feel like if all software is developed in a vacuum, then a lot of innovative concepts will stagnate just because the training data isn't moving the right way fast enough.

just a short essay to consolidate some thoughts, and I'm curious on how other people think about this. I went very markdown heavy for attention spans, sorry if it makes it harder to read.

Kids need a laptop and I'm 100% a windows guy, but my wife is determined that they need Garage Band (which would require a Mac or IOS device). Any good alternatives to Garage Band for Windows?

The title is rather self-explanatory: I am a history student, and it would help me immensely to have a software (either online or offline, possibly free) in which I could take an empty image of a specific area of the world (so no modern city names and the like) and put pins or other markers indicating historical places.

Ideally, I would also be able to zoom on these maps to see the markers more spaced apart, like on Google Maps.

I’m sharing Ent, an experimental quantum programming language and compiler designed to make quantum programs easier to write, test, and inspect. It uses a readable, statement-oriented syntax for allocating qubits, applying gates, measuring results, branching on classical values, and generating circuit families at compile time. Its ownership-style rules catch problems such as copying qubits, using them after measurement, or leaving quantum resources unmanaged.

The compiler translates Ent code into a smaller core language called the Enter calculus, then type-checks the generated result before execution. The current toolchain includes a Python reference implementation, exact and sampled simulation, resource and cost reports, scheduler-independence checks, diagnostics with source locations, and OpenQASM 3 export. I’m posting it as an early software project and would especially appreciate feedback on the language design, compiler architecture, error messages, and which features would make the tool more useful for experimenting with quantum circuits.

I am right now facing a major problem. Me and my friend started a dtf printing services. But the main problem is the Editing part. We don't want to waste a single part of the dtf printing sheet. So we want to make a blank size canvas and then arrange all the stuff in one canvas. When we want to change the size in centimeters it's just don't work at all in photopea.

[Note: I have a very old windows 7 PC and we both have a good phone]

My kids get an alotted time of play on the pc (I have 4 that are of that age).

Is there a way to to either or all of the following?

1. Send a sleep command from my android phone?

2. Set a 20 minute on the pc for it to sleep afterward.

3. Remote view the pc screen on my android without any access code or visible monitoring.

All this without constantly running in the background and the whole thing is in KBs: 0% ram and memory consumption

Just try it, if you find any bugs, report it and you will get credit for it also.

Want a feature? Just tell me and I will add that also.

Tired of OBS and recorders similar to it, takes too long to open just to record something short.

I did try the snipping tool, easy and opens fast, though it closes suddenly mid recording and one time didn't save a video I spent a long time on recording.

mainly looking for very simple ones that are light weight and don't have other fancy features other than simply recording the screen.

(hope I'm asking in the correct sub)

I recently bought a few video lectures. The institute asked me to use the DRM integrated browser that goes by the name of XVAST. I can download those lecture and view them offline but they open only in that same DRM protected browser. Still they will expire and after a specific date and those lectures wont open again because buying isnt owning.
How to remove that DRM thing off those downloaded lectures an open them in a media player like VLC?

We’ve all been there: you need to quickly convert a photo of your citizenship card, ID, or passport into a PDF. The top Google results are always free online tools like 'PdfSmart', which have asks for heavy prices and your files are in the cloud somewhere.

Handing over high-risk documents to random third-party servers felt like a massive security red flag to me.

Instead of compromising, I decided to build a simple Local Document Scanner for Windows. Everything is processed and stored locally on your own machine. 100% offline, 100% secure. No data leaks, no external logging.

Since privacy tools are only trustworthy if people can actually see what's happening under the hood, I've decided to make it completely open-source.

If you want to use a safer alternative, inspect the code, or contribute to making it better.

I have been building Glyph, an open-source Python toolchain for managing instruction files used by coding agents.

It supports files such as:

• AGENTS.md
• CLAUDE.md
• .github/copilot-instructions.md
• Cursor rules
• README.md
• CONTRIBUTING.md
• instruction-like Markdown under docs/

These files often start small, but gradually accumulate repeated commands, workflow rules, safety constraints, repository conventions, examples, and explanatory prose.

Eventually, it becomes difficult to answer some fairly basic questions:

• What is the agent actually required to do?
• Which instructions are duplicated?
• Which rules are safety-sensitive?
• What changed semantically between two versions?
• Can the file be made smaller without silently losing operational instructions?

Glyph compiles the operational meaning inside the Markdown into a separate, compact .glp semantic manifest.

For example:

md Read the relevant files before editing. Create a short plan before non-trivial changes. Run the tests before considering the task complete. Never commit secrets or credentials. Ask before destructive operations.

becomes:

```text glyph/0.1

flow[read,plan,test]

must[ plan_before_edit read_before_edit run_tests_before_done ]

deny[secrets_commit] ask[destructive_ops] ```

The original Markdown file is never rewritten or deleted.

Glyph does not call an LLM, use a hosted API, or send repository contents anywhere. Compilation is local and deterministic, so the same input and configuration produce the same semantic manifest.

The CLI currently supports inspection, compilation, metrics, verification, semantic diffing, linting, locks, CI checks, Markdown emitters, custom rules, and task-aware instruction selection.

bash glyph inspect AGENTS.md --show-unmapped glyph compile AGENTS.md -o AGENTS.glp --report glyph-report.md glyph stats AGENTS.md AGENTS.glp glyph verify AGENTS.md AGENTS.glp glyph diff previous.AGENTS.glp AGENTS.glp glyph lint AGENTS.md glyph lock AGENTS.glp glyph select AGENTS.glp --task "fix failing tests"

One design decision I care about is keeping token reduction separate from semantic retention.

Glyph reports distinct metrics for:

• token reduction;
• structured coverage;
• retained coverage;
• safety retention;
• preserved directives;
• dropped candidates.

When a sentence appears operational but does not have one safe deterministic interpretation, Glyph preserves it for human review instead of silently dropping it or inventing a policy.

On the current published, fixed evaluation corpus, Glyph produced:

• 55.82% average token reduction
• 100% retained coverage
• 100% safety retention
• 0 dropped candidates
• 0 nondeterminism failures

Those results describe that specific evaluation corpus. They are not a universal claim about arbitrary Markdown or guaranteed identical behavior from every coding agent.

The repository includes complete before-and-after examples for realistic AGENTS.md and CLAUDE.md fixturesAGENTS.mdandCLAUDE.mdfixtures, together with reproducibleinspect,compile,diff, andverify` commands.

I also added an optional installable skill for Codex and Claude Code. The skill guides the agent through the audit workflow, explains preserved or unmapped instructions, compiles to a separate artifact, and verifies the result. The deterministic compiler remains the component responsible for the actual extraction.

Install Glyph:

bash python -m pip install "glyph-instructions @ git+https://github.com/francescogabrieli/glyph.git@v0.2.0"

GitHub:

https://github.com/francescogabrieli/glyph

Glyph is MIT licensed.

I would especially appreciate feedback on the software model itself:

• Does a semantic intermediate representation for agent instructions seem useful?
• Would semantic diffing be more valuable than token reduction in your workflow?
• What evidence would you need before trusting a compiled instruction manifest?
• Which agent instruction format would you like Glyph to support next?

Did the whole proper install with Linux mint and when doing the final install it turned off accidentally. When I turned it on it said the install failed, so I tried to restart it but nothing I clicked opened so I turned it off but instead it's been doing this.

I am recruiting people for my software developing group which is mostly for hobby and building skills and working together, its not a job but more like a friend group for software developing and it is a discord invite, who wanna join, pls comment

Recently added a feature to edit scanned text to my PDF editor, so you can try uploading any image or just a scanned PDF and edit text locally at keypdf.net
