Of course, today’s smartphones already come with built‑in SOS features for emergencies in low‑network or remote areas, but exploring this LoRa Tech makes the whole idea even more fun

[dev kumar singh @Devdoingdev]

a guy is building a startup

an SOS app for tourists and women in unsafe zones — instant alerts, live location to authorities, warns you before you even walk into a dangerous area

he reached out for help on the hardware side

I got curious. asked him what he had in mind.

[dev kumar singh @Devdoingdev]

where your phone is useless. the app is useless.

so I started digging

and I found LoRa

a radio signal that needs no internet, no cell towers, travels 15km, and runs on a battery for weeks

still exploring this tech and honestly this is interesting

@_karnaditya @isha_singh06 Scariest when it says reset next month

@shushantku68275 I use this resources to learn and build AI agents

docs: https://t.co/qhuEVfuhfv

youtube playlist: https://t.co/Sev3rzah3f

or you can read blogs on google

also learn about pydantic (for data validation)

btw I am Assuming you know python

@sysxplore As I have recently started using linux distribution, I need something like this...

@pankajkumar_dev I have faced this kind of issue so many times, now it feels normal to me. I have accepted it.

New year, same mission: learn, build, share. ✨

Thank you for being the kind of community that turns ideas into action and strangers into friends. Can’t wait to see what we all create together in 2026.

Happy New Year! 🙂

At @TeamShiksha, we’ve just wrapped up our second session reading “Code: The Hidden Language of Computer Hardware and Software” by Charles Petzold together, and we’ve finished up to Chapter 4.

Hosted by @jatinkrmalik, we have so far:

- Explored how simple, real-world signalling systems (like friends sending each other messages at night using flashlights or other basic signals) naturally lead to the idea of codes and protocols.

- Looked at codes and combinations, and how constrained channels force you to think carefully about what you encode, how you encode it, and how many unique symbols you can represent.

- Connected this to Braille and binary-style encodings, seeing how information can be represented purely as patterns of “on/off” or presence/absence, and how that scales into more complex symbol sets.

- Taken apart the “anatomy of a flashlight” as a gateway into circuits: switches, current, and the idea that something as mundane as turning a light on and off is already the foundation of digital signaling.

In just four chapters, the participants have moved from “everyday objects and stories” to the brink of thinking like a computer from first principles... seeing that computers are not magic, but layers of very understandable ideas stacked carefully on top of each other.

📚 Next session:

We start Chapter 5, where we push these ideas further and get closer to relays, telegraphs, and the building blocks of digital circuits... bridging the gap between abstract codes and physical hardware.

If you’re excited by the idea of truly understanding how computers work under the hood (beyond frameworks and languages), and you’d like to join future reading sessions like this with the TeamShiksha community, join us today 😉.

Introducing: Founders Assistance by @TeamShiksha

Transform your idea into a real, working product.

At TeamShiksha, we’ve evolved from a learning house into an app studio built around product-driven development. Our community of passionate developers, guided by world-class mentors, now collaborates to build the next generation of innovative products.

If you’re a founder, investor, or side-project enthusiast with an idea waiting to take shape... we’re here to help you go from concept to launch.

We work in small, nimble teams that deliver with intent and discipline.
Our mentors ensure every project meets real-world standards... no “college project” vibes here. From writing PRDs to designing user experiences and executing reliable, scalable code, we follow a complete, high-quality product journey.

We also invest in your success... offering development credits and even early-stage funding assistance to help you reach launch velocity faster.

What we ask in return:
If your idea turns into a real-world product and succeeds, give our contributors the opportunity to join you as founding engineers... the same people who helped bring your vision to life. Meanwhile, our mentors continue supporting your engineering, product, and culture-building journey from the outside.

So, if you’ve got an idea, bring it.

👉 Apply now for the Founders Assistance Program by TeamShiksha. (link in the thread below)

Help us reach D2C founders and anyone else you think may benefit from this initiative by doing a quick Repost 🔂 of this tweet.

Remember, most organisations, never have enough people to bring about all their projects to fruition, so if you think your favourite entrepreneur is funded enough to not need these services, well, they probably do 😉

Reminder: Session with the awesome @jatinkrmalik tonight at 10 PM!!

@SecurityTrybe Not me, I have started with debian

[dev kumar singh @Devdoingdev]

filter_by method:
filter the results of a query

where method:
A synonym for query.filter()

group_by:
It group all the rows and return only the column values (which you specified) + can be used with aggregated func (count, avg , etc)
