@dharma_watch Expecting a youngster to take the pressure in just his second season or 23-24th match to take responsibility for the team bad performance. Gill have sudarshan and buttler who are top scorers but vaibhav is highest scorer for his team right now.
English

@dharma_watch @Anish1130347 He is doing what the role is assigned to him, to give explosive starts to the team. And what he can do if middle order fails or top order is inconsistent around him. He can't score the whole of target or score for Rajasthan. Senior players need to do their job and bowlers too.
English

@Anish1130347 Bhai match Kab jeetwayega ??
Cricket is a team game. Gill has single-handedly taken his team to 2nd position with just 3 batsman.
Run wo jo match jeetwaye ... or else there is no value to those runs.

All the best startup accelerators to apply in 2026 (below FULL spreadsheet):
[ Top-Tier ]
1. Y Combinator (~$500k, 7% on $125k + uncapped SAFE)
2. a16z Speedrun (~$500k for 10% + $500k follow-on)
3. Techstars (~$220k, bumped from $120k in fall 2025)
4. Founders Inc (~$100-250k for 4-7%)
5. Sequoia Arc (~$1M, terms per company)
6. South Park Commons (~$1M total, $400k for 7% + $600k guaranteed)
7. HF0 (up to $1M uncapped for 5%, repeat founders only)
8. On Deck ODX (DISCONTINUED 2022, skip)
9. Pear VC PearX (~$250k-2M for ~10%)
10. 500 Global Flagship (~$150k for 6%)
[ AI / ML Specific ]
11. AI Grant (~$250k for 7%, Nat Friedman + Daniel Gross)
12. AI Fund (~$1M+, Andrew Ng, studio model)
13. NVIDIA Inception (credits + perks, no equity)
14. Microsoft for Startups (up to $150k Azure credits, no equity)
15. Google for Startups AI Accelerator (credits, no equity)
[ Vertical / Deep Tech ]
16. SOSV (~$525k across IndieBio, HAX, Orbit)
17. IndieBio (biotech, ~$525k = $250k for 6-8% + Genesis SAFE)
18. HAX (hardware, ~$525k via SOSV)
19. Greentown Labs (cleantech, workspace + grants)
20. Activate (deep science fellowship, 2-yr stipend)
[ Crypto / Web3 ]
21. a16z crypto CSX (~$500k for 7%, SF in-person)
22. Alliance (~$500k, ALL18 starts Sept 7)
23. Outlier Ventures Base Camp (~$250k, per-chain verticals)
24. Coinbase Base Builder (varies, mostly non-dilutive)
[ International / Regional ]
25. Seedcamp (~€350k-1M first check, rolling, Europe)
26. Entrepreneur First (~$250k = $125k for 8% + uncapped MFN)
27. Antler Disrupt US (~$400k = $250k for ~9% + uncapped)
28. Brinc (~$100k, Asia + Middle East)
29. Station F (Paris campus, hosted-program terms)
30. Founder Institute ($499-999 fee + 2.5% Equity Collective warrant)
[ Pre-Seed / Idea Stage / Niche ]
31. Z Fellows (~$10k for 1%, pre-product)
32. ERA NYC (~$100k for 8%, generalist)
33. The Residency (community-first, no standard check)
34. Plug and Play (varies, often non-dilutive)
35. Build For Tomorrow (community + grants)
Four things worth knowing:
1. small program acceptance rates are higher than YC, not because they're easier, because the funnel is smaller. apply to 5-7, not 1
2. brand premium on YC is real but not infinite. Arc + Speedrun + HF0 carry signal too
3. "$X for Y%" is the only number that matters. uncapped MFNs are not free money, they dilute you on the next round
4. avoid any list still quoting Techstars at $120k, ODX as active, HF0 at $100k, or Founder Institute as "$10k for 4%". all wrong
Shared with you those where I am going to apply with my ideas and products
Terms shift annually. Verify on each program's site before applying

@Safehands_Sanju Delhi was at 120 for 1 after 11 overs when he went outside. KL rahul was already set and Nissanka scored 62 off 33 balls.
When riyan parag was made captain last year, he lost three matches in a row and had record of 4 loss and 2 wins last season. One match don't define anyone
English

@programmer_jai He went outside after a few overs and rest was taken over by Bhaiswal
English

Yashasvi Jaiswal always wanted to be a captain. But don't know even "C" captaincy
In the previous match below average DC chased 226 in 19 overs
Today test player driven GT made 226 and he was clueless and started abusing bowlers like brijesh and Archer..
Don't know about the field placement
Don't know about the bowler rotations
Don't know about the batsman's weakness
In short he knows nothing....

English

@Success28607354 RR playing DC, LSG and MI and Gujarat will play SRH, KKR and CSK. So GT win is more beneficial for csk. RR have relatively easy opponents ahead and they need to lose atleast 2 matches including today. While gt lose one and we beat them in one is desirable.

SYSTEM DESIGN MOCK INTERVIEW (WITH ANSWERS)
1️⃣ Tell me about yourself
✅ Sample Answer:
"I have 3+ years designing scalable backend systems and distributed architectures. Skilled in microservices, databases, caching, cloud infrastructure, and system optimization. Recently designed systems supporting millions of requests daily with high availability and low latency."
2️⃣ What is System Design?
✅ Answer:
System Design is the process of designing scalable, reliable, and maintainable software architectures that meet business and technical requirements.
3️⃣ What is scalability?
✅ Answer:
Ability of a system to handle increasing traffic and workload efficiently.
Types: Horizontal scaling and Vertical scaling.
4️⃣ What is load balancing?
✅ Answer:
Distributes incoming traffic across multiple servers to improve reliability, availability, and performance.
5️⃣ What is caching and why is it important?
✅ Answer:
Caching stores frequently accessed data in memory for faster retrieval.
Reduces database load and improves response times.
Examples: Redis, Memcached.
6️⃣ What is database sharding?
✅ Answer:
Splitting database into smaller partitions across multiple servers.
Improves scalability and performance for large datasets.
7️⃣ What is replication in databases?
✅ Answer:
Copying data across multiple database servers for redundancy and availability.
Primary handles writes, replicas handle reads.
8️⃣ What is eventual consistency?
✅ Answer:
Model where distributed systems become consistent over time rather than immediately.
Common in highly scalable distributed systems.
9️⃣ What is a CDN?
✅ Answer:
Content Delivery Network distributes static content closer to users to reduce latency and improve speed.
🔟 What is the CAP Theorem?
✅ Answer:
Distributed systems can only guarantee two of three:
Consistency, Availability, Partition Tolerance.
11️⃣ What is a message queue?
✅ Answer:
Asynchronous communication mechanism between services.
Improves decoupling and scalability.
Examples: Kafka, RabbitMQ.
12️⃣ What is rate limiting?
✅ Answer:
Restricts number of requests from clients to prevent abuse and maintain system stability.
13️⃣ What is microservices architecture?
✅ Answer:
Architecture where applications are split into independent services communicating via APIs.
14️⃣ How do you design a highly available system?
✅ Answer:
Use redundancy, replication, failover mechanisms, monitoring, auto-scaling, and distributed infrastructure.
15️⃣ What monitoring tools have you used?
✅ Answer:
Prometheus, Grafana, ELK Stack, Datadog, New Relic, CloudWatch.
16️⃣ Walk through a system you've designed
✅ Strong Answer:
"Designed a scalable video streaming backend using microservices architecture. Used Redis for caching, Kafka for event streaming, PostgreSQL for persistence, and Kubernetes for orchestration. Implemented CDN delivery and load balancing to support millions of concurrent users with low latency."
