I built an open-source tool to transfer large files directly between two PCs over an Ethernet cable with zero config (EtherTransfer)
Hey everyone,
Whenever I needed to move 100GB+ between two laptops or PCs, the usual options were annoying:
- Wi-Fi/SMB sharing is slow and frequently drops on large directory trees.
- Cloud storage takes hours and caps upload speeds.
- USB flash drives require copying everything twice.
- Direct Ethernet cables usually require configuring static IPs, subnet masks, or running a DHCP server.
I built EtherTransfer to make direct LAN transfers as plug-and-play as possible.
How it works:
Connect a standard Ethernet cable between two PCs (no crossover cable needed, modern NICs handle auto-MDIX).
Launch the app on both machines.
They discover each other automatically over link-local IPv4 (169.254.x.x) via UDP broadcasts.
Drag & drop files or entire folders and stream at full link speed (115MB/s on 1GbE, 1GB/s+ on 10GbE).
Key points:
- 100% offline — zero internet, zero cloud servers, zero telemetry.
- Preserves deep directory structures without needing to zip first.
- Cross-platform support for Windows (10/11) and Linux.
- Built with .NET 10 and Avalonia UI.
- MIT Licensed.

Would love feedback on transfer stability, edge cases, or features you'd like to see added.
Firefox using the most amount of Ram with more irregular jumps in CPU usage as compared to Chrome and Edge
Same tabs on all three browsers playing the same video with the same extensions. Firefox consistently has higher ram usage (don't give me that unused ram is wasted ram) and has more jumps in CPU usage as compared to chrome and edge, with edge having minimal impact on performance (it's no secret). My question is, at what point did chrome overtake firefox in performance? Im lowkey a firefox glazer and exclusively use that (typing on it rn) but i'm kinda of surprised since this wasn't the case a few months ago.
Going to sleep now will reply tom. goodnight cuties :*
I thought senior dev roles are more valuable now?
AI has crushed junior hiring, but I feel like senior devs are getting squeezed too.
I'm a full stack dev/engineer with around 20 YOE (classic ASP to VB to .NET to PHP to JS/TS modern tooling/frameworks), and looking for a job right now. I expected that experience to be an advantage, but it hasn't felt that way. Then I see reels of developers sitting on their phones, waiting for AI agents to finish their work, bored and scrolling. I can't help but think: you have no idea how lucky you are.
I'd love to have the problem of being bored because AI is doing too much of my work. /s
Any senior devs here in the same situation right now? How did you get through it? I'd really appreciate any advice. I have very few friends and network, very shy to ask them because I'm not the person they'd think to be in this position.
What's the best method/ software to Compare differences between 2 text files ?
Hello
I have 2 files I need to check and compare to spot differences between the two and edit one if necessary. Both are text files (it's a memoir) from the same source, but one's text has been edited, hence why I need to check which chapter/text has been edited.
I tried to put both texts on my screen and compare them by just reading, but its very slow and not comfortable at all
Do you know a better method or a software to help me directly spot those differences ?
Thank you
Is building your own software even worth it anymore?
Hi,
I'm a software developer and really want to build my own platform / piece of software, but to be honest, I'm starting to lose hope. Every time I come up with an idea, it turns out there are a million people that have already built it. And whatever doesn't exist yet gets vibecoded in an afternoon by a non-technical guy using Cursor or Claude or whatever. The barrier to entry feels like zero now.
Am I being too pessimistic here, or is this just our new reality as a software developer? Does it even make sense for a solo developer to sink their evenings into this if the goal is just to build a solid side hustle? Also running out of ideas by the way, so honestly I might give up on this idea.
I’d love to hear your thoughts.
Thanks!
IONOS Just Scammed Me
I signed up for a IONOS, the first month was only $10. I was very surprised to see a $136 charge on my card, for 7 contracts. 3 of the items that I was charged for were duplicated. I asked to cancel these unnecessary subscriptions and contracts because I only needed the $10 one I signed up for and I was told I was locked into a 12 month minimum contract term. What do I do? I don’t remember signing anything and that’s $1,632 dollars they want from me. Now that I’m finally doing my research I’m scared they’ll send me to collections as well. Anyone have a similar experience?
Before you start hating, I know. I should’ve looked deeper and your unnecessary words won’t hurt me as much as these ridiculously high charges. I’ve learned my lesson.
Our website is never really finished
We wrapped up a full redesign a few months ago and thought we'd finally be able to focus on other things instead we've been making changes almost every week like new pages, updated screenshots, small copy edits, fixing things that looked different after one change it just keeps going none of it is difficult on its own but it adds up fast.
I don't even think about the website as a project anymore it's basically become part of our weekly routine now looking back building it was probably the easy part but keeping everything current has taken a lot more time than I expected
