ניתחתי את התשואה השנתית של קרנות גידור בנאמנות אל מול מדדים. זה לא הרבה זמן, אבל כן אפשר לראות שיש מנהלים שעושים עבודה יותר ופחות טובה.
מסתבר שאין מסחר בחוזים עתידיים בבורסה בתל אביב דרך IBI, בטענה של "החלטת חברה". יש בתי השקעות אחרים שמאפשרים מסחר בחוזים עתידיים בארץ?
Hi @Apple! 🥰 Looks like you're using Dopamine internally on iOS 26, would you kindly submit a PR to the GitHub repo? Oh, and don't forget to unban @opa334dev's developer account, that would help future Dopamine releases! x.com/_gilboz/status…

Hearing about new CVSS dashboards vs a real offensive iOS talk on August 4th. Register now: nooffensecon.org/registration
@beersehva @moshebs11 למה s&p עשו מעשה נבלה? הם נכנסו לנאסדק 100, ולא נכנסו לs&p500 כי שם לא הגמישות את החוקים
Excited to organize NoOffense again. Looking forward to seeing the local offensive community in Tel Aviv.
NoOffense is back on August 4th. Registration is now open (link below).
IL Researchers - get ready for another great night for the community! This time - talks are doing a comeback! There's at least one AMAZING talk that I'm aware of, will yours be there as well? Stay tuned...
We're back for the fourth iteration of NoOffense, and we are looking for interesting talks. Reach out to @guyru_ to submit yours.
נואופנס חוזר באוגוסט הקרוב. אם יש לכם הרצאה מעניינת, דברו איתי.

@tonymewprano @zaafonin @CellebriteLabs But how would you expose it via tool calls? Seems like you would end up with something like ghidra-rpc, but with additional overhead
We're mostly an IDA shop at @CellebriteLabs, but I decided to play around with Ghidra. My main motivation was to experiment with agentic reverse engineering techniques. The result is an agent skill for Ghidra, which we are releasing publicly: github.com/cellebrite-lab… >>
Inspired by @guyru_'s ghidra rpc agentic skill, I ported my mcp server for @HexRaysSA IDA Pro to be a rpc skill + plugin as well. What can I say, speed improvements and less tokens needed, it was fully worth porting it. Go test it :) github.com/bkerler/ida_rpc
@beersehva זה מעלה את השאלה האם מעל קצבה מסויימת, לא עדיף להסיט כסף להשקעה באפיקים רגילים? תשלם מס רווחי הון אבל הוא יהיה נמוך יותר מהמסך השולי
@AmirKochavi הרכבת בהוד השרון עדיין לא חזרה לתדירות מפברואר (שהייתה אף היא פחותה ביחס לתדירות עד ה-7 באוקטובר)
@silentwarble Pi is very minimal and hence you can turn it into whatever you want. Most other harnesses come with huge system prompt and lots of tools that consume context. That might be helpful for development, but it makes them less efficient for research.
@SMT_Solvers @thegrugq @CellebriteLabs If it were developed by the Mossad, it would really complement Ghidra being developed by the NSA, right?
@eliasbchlny @CellebriteLabs I wasn't aware of the those projects. Which kind of makes sense given the timeline of both projects (looks like the project didn't exist when I started my work). Some people in my team have been trying the SQL approach, at this point we're experimenting to see what works best.
@eliasbchlny @matrosov Skills based approach allows the agent to chain together multiple tool calls and write bash or python scripts to perform complex tasks. MCP requires the LLM to do it directly as tool calls and is less efficient
@y0ush4 MCPs are inefficient compared to skills when it comes to repetitive tasks. x.com/guyru_/status/…
@zaafonin @CellebriteLabs Agents are very efficient in writing bash and python code. The approach I took allows the agent to combine the two and write scripts that interact with Ghidra and chain complex interactions together. The MCP approach requires the agent to perform each interaction itself which>>
MCP is slow for RE-heavy projects and, in some cases, is unstable. ghidra-rpc is way faster than MCP and scales more efficiently in a multi-agent setup, since it outputs structured JSON.
We're mostly an IDA shop at @CellebriteLabs, but I decided to play around with Ghidra. My main motivation was to experiment with agentic reverse engineering techniques. The result is an agent skill for Ghidra, which we are releasing publicly: github.com/cellebrite-lab… >>
@zaafonin @CellebriteLabs That's the same reasoning behind Pi's decision to not support MCPs natively.
@zaafonin @CellebriteLabs is less token efficient and requires the agent to perform way more tool calls directly.
