Deda Method

The internally displaced tribal families in Godavari Valley continue to practice the ‘deda’ method to preserve seeds.

  • It is a traditional, eco-friendly, fool proof seed preservation method.
  • Prepared byMuria tribes, also known as Gutti koyas.
  • Preservation – The seeds are preserved in leaves and packed almost airtight to look like boulders from a distance.
  • The packaged seeds are, in turn, woven with Siali leaf (Bauhinia vahlii), which is locally known as ‘addakulu’ to make the deda.
  • Multi-layer protection - A deda has 3 layers.
  • In the first layer, wood ash is spread inside the Siali leaves.
  • Later, the ash is covered with lemon leaves to form a casing, and, lastly, the seeds are preserved inside the casing and sealed.
  • Shelf life – The stored seeds can be used for cultivation for up to 5 years but these tribes prefer to preserve them for up to 3 years.
  • Crops preserved – Seeds of pulses like the green gram, red gram, black gram, beans and seeds of other food crops.
  • Significance – It guarantees protection of seed from pests and worms.

Internally displaced Muria Tribes from Chhattisgarh settled along the banks of the Godavari and Sabari rivers in the Godavari valley in Andhra Pradesh and Telangana whose habitations are known as habitations of the Internal Displaced People (IDP).

The new flagship model GPT-4O was launched.

  • Released byOpenAI
  • Aim – To accept audio and visual inputs in addition text and to generate output almost flawlessly.

The ‘o’ in GPT-4o stands for “omni”, which means it can receive multimodal inputs through text, audio, and image. ChatGPT still receives text input to provide output.

  • Mechanism – It works by clubbing 3 models: turning the user’s voice into text, carrying out operations, and returning an audio-based result.
  • Response time – 232 milliseconds for audio input, while its average response time is 320 milliseconds.
  • It uses the usual fillers, or sometimes repeats part of the question to cover for this latency.
  • Response voice – In most of the demo clips shared, the voice sounded female.
  • Unlike more basic iterations they were expressive, friendly, and even affectionate, sounding more like a friend or someone closer rather than a machine-generated voice.
  • Activities – It can do a range of activities like
    • Turning a picture of a man into a caricature.
    • Creating and manipulating a 3D logo
    • Generating meeting notes based on an audio recording
    • Designing a cartoon character, and even make a stylised movie poster with real people’s photos.
    • Assisting a child in solving a math problem by setting a game
    • Assessing the readiness of user for interview
  • Advantages2 times faster, half the price, and has 5 times higher rate limits compared to GPT-4 Turbo.

OpenAI claims it to beat existing rivals such as Claude 3 Opus and Gemini Ultra 1.0, as well as its own GPT-4 offering, in several areas across text evaluation and vision understanding evaluations.

  • Safety – It has safety built-in by design across modalities, through techniques such as filtering training data and refining the model’s behaviour through post-training.
  • It has new safety systems to provide guardrails on voice outputs.
  • Challenges – It has omitted the capacity of generating a video like trailer and had also made some slip-ups and errors when demonstrating its abilities
    • Example: While converting 2 portraits into a crime movie-style poster, it initially produced gibberish instead of text.

  • The missile will be imported and some parts like sights, launcher, and the battery will be assembled/ manufactured by Adani defence.

The Indian army is also set to receive its 1st of two Israeli Hermes-900 Medium Altitude Long Endurance Unmanned Aerial Vehicle (UAV) assembled by ADSTL in Hyderabad.
