kinda crazy that crying at the kitchen table while your dad explains your physics homework the wrong way is no longer a thing
YOUR PHONE IS STEALING YOUR LIFE FORCE
Personal update: I am joining @aave Over the past few months, I have had the chance to work closely with their engineering team. I have been impressed by how they approach security and by their attention to quality I am excited to continue helping them secure the future of DeFi
I'm often asked "What are we going to do with $72M" 90% of our spend is on people. Talent density is a startup's only real competitive advantage.
Most of the KYC friction you experience when buying crypto has nothing to do with compliance. @AlexKFine says it's poorly built risk models and there are better ways to manage the underlying risk without making the user experience painful. 99%+ of Fun's volume is fiat to
I was on the board of @ehsanik's company before Anthropic acquired it. She is a force of nature. Brilliant. Relentless. Deeply caring. No one should have to miss their wedding because their family is trapped in a war zone. No one should live with constant uncertainty about the safety of the people they love. No one should have to live with immigration uncertainty while giving so much to the country they call home. Iranians have contributed enormously to America and the world. My heart goes out to them.
Today I was supposed to be on my way to Türkiye for my wedding, to meet up with my family and have them finally meet my partner and husband. We had everything planned. We chose Turkiye since it's close to Iran and my partner and I could both go there and have our families meet
Today I was supposed to be on my way to Türkiye for my wedding, to meet up with my family and have them finally meet my partner and husband. We had everything planned. We chose Turkiye since it's close to Iran and my partner and I could both go there and have our families meet each other. We were supposed to get married with our close family and a small group of friends on a boat on the Mediterranean Sea at sunset. Because of the war, all flights to and from Iran are cancelled and my family can’t leave Iran, so we had to call off the wedding. Instead, this is how my day looked like. I woke up to a reminder to call my grandma (I used to call her every Friday morning). I snoozed the reminder until next Friday, just like I have done for the past many years. I can’t call her like our tradition these days because there is no way to call home. All international calls to Iran are blocked, and the internet is fully shut down by the regime. I got to work and right as I opened my computer I received an email I had scheduled to send to myself 5 years ago: “Apply for citizenship.” This summer marks 11 years of being in the US and 5 years of being a green card holder. I am now eligible to file for citizenship, but it doesn’t matter because an executive order was signed a few months ago that banned all Iranians from applying for any visa or citizenship. At lunch I opened Twitter just to see what’s up in the world and saw the news that those who don’t have a green card now need to leave the US before they can get one. This means every one of my Iranian friends who are here on a visa now has to go back home (on which flight?) to get a green card??? As if it’s that easy? We all know getting back to the US for Iranians is a huge challenge (months and months of waiting for a visa, with a chance of never being able to come back). And this is just a normal Friday for an Iranian. These days, when people ask how I’m doing and how I’m handling everything, I just say: It’s okay, it’s okay. It will be okay some day. But the reality is: nothing is okay. I’m in constant pain. I haven’t seen my family and loved ones in years, I barely hear about their wellbeing, and I’m constantly worried about them. I’m just burying myself in work because that’s the only distraction that can save me from losing my mind. I’m not okay. None of us are okay. We are just barely holding it together…

1/12 Lots of people asking if I make every Asian male I interview insult Kim Jong Un - for the avoidance of doubt, I only ask someone to insult Marshal Kim when I'm already confident they're North Korean and trying to defraud. But how did I know Taro was North Korean? 🧵

Anyway I definitely agree with x.com/tjbecker/statu… (not surprising since we co-led the same AIxCC team and work together :P) The top capabilities come out from best models PLUS best scaffolding. You can compensate for some losses in one with the other; both provide uplift
@moyix @ortegaalfredo IMO the post is "directionally correct", but the sloppy experimental method leads to severely overstated conclusions. The reality is that you need *both* really strong models AND sophisticated scaffolding to maximize bug finding. Opus 4.X and GPT-5+ are already quite strong!
@Faraz_z1 خیر مشکل شکم سیری، نخوت (که این یکی مشخصا درباره شما صدق می کند)و وقاحت است. هر نوع عدالت یا انتقام که از تعداد این جانوران درنده خو بکاهد به صرف خودش واقعه ای مثبت است.
ناخودآگاه آدم پدیده ی عجیبی است. مکالمه ای بین دونفر از ترک وطن کردگان که اینجا با آنها آشنا شدم خواندم که ناله برای «مرکز محاسبات شریف» سر داده بودند. اولین چیزی که در ذهنم متبادر شد آباژورهایی از پوست انسان بویژه از پوست زندانیانی که «خالکوبی زیبایی» داشتند بود که چند نازی در اردوگاه بوخنوالد سفارش می دادند. هنوز نمی دانم دقیقا چرا این به خاطرم آمد. ولی اندکی بعد خودم گفتم آیا وقتی خبر تجاوز به صدها و احتمالا هزاران دختر نوجوان اسیرشده در اعتراضات ۱۴۰۱ در بازداشتگاههای مخفی را رسانه ای مثل سی ان ان گزارش کرد همینقدر برافروخته شده بودند؟ آیا آنچه اتفاق می افتد به عنوان «یک بسته با همه چیزهایش» که در این مورد خاص برای این دو بیشتر نابودی خاطره و نوستالژی است، ارزش به هلاکت رسیدن محمد کاظمی، حسن محقق ومجید خادمی، غلامرضا رضاییان، اسماعیل احمدی و دیگر فرماندهان این هیولای اهریمنی که چنان رنج عظیم و بی پایانی را بر دخترکانمان وارد کردند را نداشت؟ آیا طلب فهم این موضوع تقاضای بزرگی است؟ آن هم در زمانی که میلیونها هموطن، این روزها نه فقط برای خود، نه فقط برای ایران بلکه بهتر است بگویم برای همه دنیا در حال فداکاریهایی بزرگی با تحمل این جراحی عظیم با سرنوشت نه هنوز کاملا مطمئنی هستند.
Using human shields to protect bridges and power stations proves our enemies views Israel and America as more compassionate than themselves and view this compassion as a weakness to be exploited.
