@sahajsarup @Swiggy Recently happens to me too with blinkit delivery agent. They just don't want to deal with cash because then they have to manage returning change

@vaxryy I just saw your #omacon presentation and I must say that I'm an avid user of Hyprland's group feature so, thank you for maintaining it, even though you hate it.

🚨 Twilio charges $0.0079 per SMS. Someone just turned any old Android phone into a free SMS gateway. Unlimited messages. $0.

It's called SMS Gateway for Android.

Install it on any Android phone. It becomes a full SMS sending and receiving server with an API.

No Twilio. No MessageBird. No per-message pricing. No contracts. Just an old phone and a SIM card.

Here's what's inside this thing:

→ Send and receive SMS through a REST API from any app or service
→ Works with any Android phone running 5.0 or newer
→ End-to-end encryption. Messages are encrypted before they leave the device.
→ Multi-SIM support. Use multiple SIM cards on one phone.
→ Multi-device support. Connect multiple phones to the same account.
→ Real-time webhooks for incoming messages
→ Multipart messages with auto-splitting for long texts
→ Track delivery status of every message in real time
→ No registration required. No email. No account in local mode.

Here's the wildest part:

That old Android phone in your drawer that you haven't touched in 2 years? Install this app. Insert a SIM card. You now have your own private SMS infrastructure.

Two-factor authentication. Order confirmations. Appointment reminders. Notification alerts. All the things startups pay Twilio thousands a month for.

Free. Running on a phone you already own.

Startups spend $500 to $5,000/month on SMS APIs. This costs the price of a SIM card.

@Scorpiopt @LundukeJournal @dhh Tiling WM is not for you. You can enable client side decoration and add icons to the waybar for traditional mouse intensive desktop use.

Okay I think I finally found a good use for @_chenglou 's Pretext.

A resume builder that always fits on one page
with realtime rendering.

[Rishav Bhardwaj @rishavbha]

@sahajsarup I've recently used it (around dec-jan) Didn't enjoy the experience due to poor performance of java and no wayland support(whole IDE work under xwayland 🙁) then I rewrote my project in rust + raylib @raysan5 much better experience

My dear front-end developers (and anyone who’s interested in the future of interfaces):

I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept):
Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

EXCLUSIVE: Xbox One has finally be HACKED!!

After 12 years, it was thought to be “unhackable”.

Here's a summary of what it means:
• Markus Gaasedelen talks at RE//verse 2026 about the Xbox One's "unhackable" security.

• A decade-long unhack streak comes to an end due to a hardware glitch on the boot ROM.

• Bypassed MPU jails, randomized stalls, efuse/ECC protections, and crypto chain. Achieved PC hijack, supervisor execution, full efuse/key dump, decrypted stages (SP1, SP2, 2BL, firmware). Unpatchable on original fat models.

• Game preservation must be done by others (he no longer plays games and does not intend to pirate them), but this hack allows for full decryption of games, apps, and other content.

• Repairs are now possible, including unbricking NANDs, fixing firmware, and decouple/repair disc drives (e.g., swaps for emulation). DIY solutions for eMMC failures which can extend console life.

• Only minimal setup is needed, custom tools for power traces, I2C diagnostics, efuse reads, GPIO taps. Glitch via crowbar voltage on North Bridge rail.

• Requires 3-4 wires (efuse channel, GPIO, DAT anchor), cap removal, and used AI for boot ROM emulation to simulate attacks.

• Glitch rate ~1/million; during days-long campaigns.

• Limited to 2013 models; later consoles (S, X, Series) have been hardened further.

@theo She using linux why are you ruining it for her by making her switch to Mac?

@tsoding Even other i3 users can't use your laptop if you've setup custom keybindings

@sahajsarup @TPLINKUS companies knows the most profitable business is data. And hence the best way to collect it, is to have an app installed on their customers phone. Sad reality of IoTs

Rust devs are gonna hate this but it's true....

Every memory safety bug you’ve ever seen in C use after-free, buffer overflow, whatever is a skill issue, not a language issue.
the computer does exactly what you told it to do, you just told it to do something stupid. malloc() gives you memory. free() gives it back. If you use it after free(), that's on you.
that's like blaming the knife when you cut yourself.

C assumes you're not an idiot. modern languages assume you are. that's the difference.
C built trillion-dollar infrastructure. your OS. your browser. your database. all of it. Linux has been running the internet for 30 years. It's fine.

If you can't handle managing your own memory, that's valid. Use Python. Use Rust. Use whatever. but don't pretend C is broken because you dereferenced a null pointer one time.

> The language isn't unsafe. You are.

If you need a list of ideas for what to build, please don't build anything, this profession is not for you.

@DanHollick I'm really glad that I signed up for it
