@tryhackme just released Capability Score. Checked mine - 76 that too after a month gap on platform for travel + a conference.

Bro casually opensourced what companies are spending millions on and are charging hundreds and thousands of dollars from users for biological age tests. 🔥🔥🔥

[Nikhil Yadala @nikhilyadala]

You want to get your biological age tested. You search Google. 100 different tests. You pick a few. They all give you completely different numbers.

Whom to trust?

How about you trust no one. Take control with OpenAge. https://t.co/IyEvC3hyD2

[Sai Krishna Kothapalli @kmskrishna]

this dude said your biological age drops 7 years after one soccer game… the whole industry is cooked 😂

@leododev Thanks so much

My 256GB MacBook Air M1 hit its limit. 😫

Started deleting apps, keeping only essentials. But the storage kept disappearing...

Found the culprit: 8GB+ of duplicate node_modules across multiple projects. Every project had its own copy! 🤦‍♂️

Today I'm making "cruft" public so you can reclaim your storage too!

Try it: npm i cruft-cleaner
GitHub: https://t.co/AisFiHP7LI

I'd love to hear:
How much storage did YOU clear?
What improvements would you like to see?
Let's build this together!

Instead of manual find commands, I built "cruft" - an interactive terminal tool that hunts down node_modules, Python venvs, build folders, cache across your system.

Beautiful TUI with checkboxes, safe confirmations, zero dependencies. Been my secret weapon for a year! 🚀

Some great news! Zscaler @zscaler has acquired SquareX @getsquarex this week: https://t.co/9oB2uPNLmk

As I reflect on this journey, I keep coming back to the pivotal moments that led to the founding of SquareX — and ultimately to where we are today.

One moment stands out above all others: our seed investment from @peakxvpartners (previously Sequoia Capital SEA).

I’m deeply thankful and grateful to Shailendra @sjs_day1 and the entire Peak XV team for the trust and belief they showed us at such an early stage. I still vividly remember Jeswin Mathai @jeswinMathai and I sitting in their office, walking through live attack demos in the browser — showing how an adversary could escalate from a browser-based foothold to effectively taking control of an entire computer.

What stayed with me wasn’t just the diligence or the questions — it was the twinkle in their eyes. The excitement around how fundamental and interesting this problem was, and the shared belief that if we could solve it natively in the browser, in a ubiquitous way, with just an extension, it could meaningfully change the security landscape.

I highly recommend Peak XV to any deep-tech founder. They are an extremely long-term, patient, and truly a founder-first investor. Throughout our entire collaboration at SquareX, I always felt they backed us in the decisions we made. That kind of unconditional, unwavering support mattered immensely — especially in a domain that changes as fast as security, where innovation is often driven by what attackers are doing next. That trust gave us the creative flexibility to take bold bets, iterate quickly, and stay focused on solving the right problems.

I’d also especially like to acknowledge Anandamoy Roychowdhary @smdcmc , Ying Jie Tan, Rajan Anandan (@RajanAnandan) , and many others at Peak XV who supported SquareX along the way. Thank you all so much — your guidance and belief made a real difference.

I’m grateful we were able to build this together, and I’m excited to continue watching Peak XV do amazing investments.

Thank you 🙏

I want to give Burp Suite Certified Practitioner Exam. However I don’t have the burp suite pro version.

Can anyone lend me burp pro for the exam duration of 4 hrs 😅?

[Chetan Chinchulkar @Chetan_CMC]

@coffinxp7 Let me in 🤩🤩

[Chetan Chinchulkar @Chetan_CMC]

@sergeynazarovx Soo true initially I thought its issue on my side cause I have low storage. I spent Rs30000(~$300) and got new SSD last week and cleared about 80 Gigs
Restarted the Mac but issue still persists 😣
One of the reason I updated to Tahoe was new spotlight which is so much broken 😒

@8ap Flights at Hyderabad are getting delayed saying "flights from Pune didn't arrive so we've to delay other flights...."
What kind of logic this is @IndiGo6E??

[Chetan Chinchulkar @Chetan_CMC]
