Resilient individuals view challenges as opportunities to grow rather than as permanent obstacles.
They understand that discomfort and failure are part of the process, and they use these moments to sharpen skills, gain perspective, and deepen their inner strength.

Effective Immediately, all organizations using PHP for their systems are advised to be prepared for an update addressing two critical vulnerabilities. PHP is widely used for web applications. These vulnerabilities often provide a direct path to the server's file system or database. If an immediate update is not feasible, it is recommend that organizations take the system offline until it can be fully mitigated. NSA will follow up shortly with more specific guidance.

What if Nigerian tech came together to build tiny tools that actually fix Nigerian problems?
Not startups, not pitches, just working prototypes.
eVoting, politician profile log, power outage maps, and any other tools suggested by the community.
Small tools with real impact and open source.
This will allow us know what is needed and how to solve our society problems with tech.

You've been using Linux for years. But you're still doing things the hard way.
Here are 7 commands that'll save you hours:
1. Forgot to add sudo?
- Type `sudo !!`
- It repeats your last command with sudo. No retyping.
2. Just created a file?
- Use `vim !$` to open it.
- The !$ grabs the last thing you typed.
3. Can't remember that command?
- Press Ctrl + R and start typing.
- It searches your entire command history.
4. Made a typo in a long command?
- Type `fc`
- It opens your last command in an editor. Fix it and save. Done.
5. Jumping between folders?
- Use pushd /some/path to save a location.
- Use popd to go back.
- No more typing long paths over and over.
6. Want to see your folder structure?
- Type `tree -L 2`
- Shows everything like an actual tree. Much cleaner than ls.
7. Need to go back to your last folder?
- Just type cd -
- Takes you right back. Simple.
Bonus:
Stop writing `cat file | grep something`
- Just write `grep something file`
- Does the same thing. Way cleaner.
I've used Linux for years. These small commands save me time every single day.
Bookmark this. Your future self will thank you.

Dear Founders, CTOs, Managers, and Developers,
I want you to read the quoted tweet and genuinely imagine this happening to your own product, the one you’re building or have already built.
The truth is, the founders of Bunni probably never took security seriously. And just like them, many of you still don’t, because “security doesn’t make money,” right? “We’re a small business,” “hackers won’t bother with us,” “we’ll deal with it later.”
That mindset is exactly how companies end up in situations like this.
Every time I get the opportunity to speak with people in your position, I emphasize one thing: invest in security early. Hire at least one competent security engineer. Budget for external penetration testing, not for compliance, but to protect your brand, your customers, & your reputation.
Security might not directly generate revenue,
but it prevents you from losing everything you’ve built.
Yes, security is expensive.
Yes, security is a choice.
But the cost of a breach is a hundred times greater, and when that day comes, you’ll realize it’s no longer a choice, it’s a debt you’ll have no option but to pay.
Please, take this as a wake-up call.
Reflect, & start taking security seriously, before someone else forces you to.
Help tag any founder, engineering manager, or developer to read this.
Hello everyone, it is with saddened hearts that we announce the shutdown of Bunni.
The recent exploit has forced Bunni's growth to a halt, and in order to securely relaunch we'd need to pay 6-7 figures in audit & monitoring expenses alone – requiring capital that we simply don't have. It'd also take months of development & BD effort just to get Bunni back to where it was before the exploit, which we cannot afford. Thus, we have decided it's best to shut down Bunni.
Here's what will happen:
- Bunni users will still be able to withdraw assets via the Bunni website until further notice.
- We intend to distribute the remaining treasury assets to BUNNI, LIT, and veBUNNI holders based on a snapshot. However, the validation of the legal process is ongoing, and the exact details of the distribution will be shared at a later date once the legal process is finalized. Team members will be excluded from the snapshot.
- The Bunni v2 smart contracts have been relicensed from BUSL to MIT, enabling everyone to utilize our innovations such as LDFs, surge fees, and autonomous rebalancing. We have pushed the AMM space forward by a generation, and it would be a shame if our efforts went to waste.
- We will continue working with law enforcement to recover the stolen funds from the exploiter.
Thank you to everyone who has supported us throughout our journey to push DeFi forward.
