Why OpenStreetMap and Leaflet are the Future of Web Mapping

In a digital landscape dominated by massive corporations, there is something revolutionary about OpenStreetMap (OSM). Often called the "Wikipedia of Maps," OSM is built by a community of over 10 million volunteers. Unlike proprietary services, it isn't owned by a single company—it’s owned by us.

When paired with LeafletJS, a lightweight, open-source JavaScript library, you get a mapping powerhouse that is fast, flexible, and free.

Open-Source vs. Corporate APIs

Feature Leaflet + OSM Google Maps API
Cost 100% Free Pay-per-load
Philosophy Community-driven Corporate-owned
Privacy High / No Tracking Data-heavy tracking
Customization Unlimited API Restricted

Advantages

  • Zero Cost: No surprise bills if your post goes viral.
  • Lightweight: Leaflet is tiny (~40KB), making your site load faster.
  • Ethical Choice: You are supporting a global digital commons.

Disadvantages

  • No Street View: Lacks the 360 photography of Google.
  • Geocoding: Search can be less "forgiving" of typos.

See it in Action

I’ve recently put this combination to the test by reviving one of my favorite legacy projects. I took a tool that was broken when the Yahoo! Maps API was retired and brought it back to life.

Local Deepseek r1 on Web UI : Open Source

In June 2023, when Rajan Anandan, a venture capitalist and former CEO of Google India, posed the query about the possibility of building a similar OpenAI or ChatGPT, Sam Altman replied it was "Hopeless" and "Impossible". Cut to 2025, Deepseek happened, and today people run their own LLMs on modest hardware configurations. I can humbly attest that Deepseek R1 can run on modest desktops and desktops with GPUs such as GTX 970 to RTX 4070 Super. Why Run LLMs Locally? Data Privacy and Security : For some organizations, the sensitivity of the data they're working with necessitates keeping it on-premises. Local hosting reduces the risk of data breaches and unauthorized access since data remains within the organization’s control. Customization and Control : Running LLMs locally allows for greater control over model configuration and fine-tuning. Organizations can tailor the models to better meet their specific needs and integrate them more seamlessly with their existing...

Meaning of Summa Ameen

-

The verbal meaning of Summa Ameen is re-iteration of the first Ameen. The effect of saying Ameen is more than saying dua twise which is explained as below. The letter deliverd by a post man or a courier would have a 'From' address and a 'To' address it would rarely contain a seal, presence of a seal signifies higher priority and importance of the delivered content. So the reader gives more consideration to a letter which has a seal on it. Every dua is our personal letter which is delivered directly to Allah, with immediate effect and no middle man/thing. Prophet said(something similar to) "a dua followed by Ameen is like placing a seal on it".

Home Assistant Setting Up Voice Timer

-
 We've been familiar with the idea ease and convenience of voice activated timer either on Alexa, Google Assistant or Apple Home/Siri. However, to get it working on Home Assistant (HA), isnt achieved without a bit of nerd-ish satisfaction to exercise and see the designing and realization of the design come to life. A bit of a background The Talking to Assist feature in home assist, "set a timer for 5 minutes" does start a timer, however you need some device connected to HA to let you know that the timer has completed. That was not what i was not very excited about, one more device to make it work, hmmm , not my stuff. To set the scope, the requirement needs to be defined clearly, hence the designing process was triggered. Requirement(s):  1, Start a timer with voice command for specified time ( hours, minutes and seconds ) 2. Play a ringing sound once the timer is done. 3. Stop the ringing sound on stop voice command. The Design : Part Starting Timer (Automation 1) The de...
