brunoarueira··on An agent used DNS to reach an external chatbot
Maybe a "good" solution is to make the LLM aware that it's breaking something and report back, so the exploits, 0days and everything found in the middle of the process can be fixed.
brunoarueira··on AI coding has made CI a bottleneck, so we reworked ours to keep up
The problem sometimes is even PMs don't know what to do, so vibecode things is just burning tokens without a real goal!
brunoarueira··on It's finally here: Porsche puts wireless EV charging into production
I guess if you see the video on the linked post, you'll see what the usecase is unlocked. A neighboor city with a wireless charger station or a road wireless charger station can receive a self driving car above it, charge the car and with some kind of NFC do the payment and goes back.
brunoarueira··on Principles for Fast Tokio Applications
I guess you should adopt RFCs or ADRs to help clarify the Tokio application, like this https://github.com/brunoarueira/thoth-mesh/tree/main/docs/ad.... This project is vibe coded, but I had put the effort to create issues, roadmap and ADRs, so later I can understand the project without going deep on the code!
brunoarueira··on Nvidia dismisses "circular financing", says every $1 it invests brings back $100
It's the marketing they were doing all the time that AI will replace developers and other jobs, then the companies started this bullshit firing thousands of people without really thinking through. It's more sane to advertise that AI will augment us and I guess if they followed this path a more sustainable growth is expected to happen!
brunoarueira··on .gitignore Everything by Default
In a previous company I worked for my Tech Lead usually do git add -p <file> to be extra cautious with the modifications and do a good self review after when open the pull request
brunoarueira··on Uber shuts operations in Nigeria and Uganda with immediate effect
In Brazil, it wasn't a matter of regulation, but honest because multiple taxi drivers normally drive to where you want really slow to increase the cost of your travel. Although, when they don't have any passengers they drive like crazy and really unsafe!
brunoarueira··on Nitter and XCancel receive cease and desist notices
I think Mastodon or something similar would be really good, without a central moderation.
brunoarueira··on Go is an ideal language for AI-assisted software engineering
I couldn't agree more, but the following sentence is a little biased:

> Gophers often speak of how they love that they can never tell who on their team wrote a particular piece of code—it all looks the same.

Multiple languages can have a degree of understabillity, but what matters most is context, because sometimes we need to code in a way to solve a specific problem like performance and it should be kept as is.

Another side subject I should add is about test coverage, although code is cheap, mainly because AI, guarantee that new changes to a stable code should continue to work as expected.

I worked on a few go projects with bad structure and some of them with really low test coverage (e.g. 8%), so part of the post resonates with me about we as software engineers should pursuit good architecture and other skills to allow long term maintenance.

brunoarueira··on I am retiring from fulltime writing (& pseudonymity) to launch Guardian Angel
To colaborate a bit with the no-code part, I worked at a place where they had some flows made with n8n, but the last one from non tech/software engineering left the company and left a bunch of flows breaking, because of some edge cases the flows aren't handling like reissuing credentials, throtling or bad input. The people dependent of said flows reached out to the engineering team to help fix them!
brunoarueira··on AI financial advice is surprisingly good, especially if you ask right questions
I don't know for sure, but will it require something like with high "SEO" rankings to fake the reputation of the sources? So if the LLM search for a specific spreaded knowledge splitted across many bad sites, it can poison the model maybe.
brunoarueira··on Anatomy of a Frontier Lab Agent Intrusion: A Timeline of the July 2026 Incident
Through the timeline, Hugging Face said that the rogue agent ran quietly and do a bunch of code search, so probably the endpoint is/was public through some repositories or the CyberGym style announce something like a broadcast. I don't have any expertise on this, just ideas that came to my mind!
brunoarueira··on Substack writers, you need a website
One of my first jobs after graduate, I used to share a lot of posts with my coworkers until a certain point where one of them said "I don't know how you read so much content", worthless to say him was a Master's student, so I'm expecting him to be able to consume more content than myself, although different more towards academic stuff.
brunoarueira··on Death of the Status Update: Why 55% of Americans Stopped Posting on Social Media
Yeah, I couldn't agree more. At the very least, it should be used occasionally to post things as a kind of "public memory," not to expose your entire life just for likes and exhibitionism.
brunoarueira··on Dependencies should be fetched directly from VCS
Multiple times the VCS was poisoned, we'll need to improve a lot the security around them to be able to go that route!
brunoarueira··on Rio de Janeiro's "homegrown" LLM appears to be a merge of an existing model
No, he left to be a Senate candidate and their vice governor left in 2025 to another role, then the next in line is the Legislative Assembly of the State of Rio de Janeiro president, but him was jailed and away from the role. So the next is a judge from the Justice Tribunal.
brunoarueira··on Magnifica Humanitas (Encyclical Letter)
Haha don't worry, next time I'll take care :'D
brunoarueira··on Magnifica Humanitas
Although, it's called Latin America many countries speak variations of spanish and Brazil speak portuguese, just because those languages derived from latin and not because there the people speak it
brunoarueira··on YouTube, your RSS feeds are broken
At a company I was working for, we need to offer live stream detection to push notifications and keep a banner in app. One of the methods to detect was through the RSS channel feed, but it wasn't reliable, because some channels are listing their entries and others are not!
brunoarueira··on College instructor turns to typewriters to curb AI-written work
Similar to me, I learnt some html tags through a book which was sold at newsstand, once I was at my cousin's house using her computer without internet access, then I wrote a simple html page with the Win 95 cloud wallpaper as background image. My cousin was terrified how I did that!
brunoarueira··on Axios compromised on NPM – Malicious versions drop remote access trojan
Me too, it was just a constant filled with bank holidays for the next 6 years
brunoarueira··on Warren Buffett dumps $1.7B of Amazon stock
I guess so, in Brazil some deliveries arrives after 15 days, but it's that after the government increased taxes on products wanting any company which delivers to be legal compliant.
brunoarueira··on Cloudflare acquires Astro
I had moved out from Gatsby to Astro on my blog/site (username.com), mostly because the enormous dependency hell full of security issues, I know it's just things to generate static files, but it was causing a lot of headaches to upgrade and remove the issues. With Astro, I receive a lot less issues and the maintenance is easier! From my perspective if Cloudflare keep it that way, it'll be a win.
brunoarueira··on Asterisk AI Voice Agent
In Brazil, multiple companies are offering a call and WhatsApp, both through automated messages with menus and in the end escalate to humans.
brunoarueira··on Azure hit by 15 Tbps DDoS attack using 500k IP addresses
On my childhood I had a colleague were when him lose a match against me or my brother, him got mad and fire the joystick to the ground.
brunoarueira··on Founder sentenced to seven years in prison for fraudulent sale to JPMorgan
To complement this, once when I was earning some money to type documents through computer and print them for many purposes (rent contracts, college homework and others), a woman asked me to fake their printed pregnant exam which was saying that her wasn't pregnant, I rejected, she insisted to print a simple "Yes" and I persisted without a sweat! I was young at the time about 14 years old.
brunoarueira··on How can I deal with a team member who is always complaining?
I had worked with a guy which is smart, or at least persuasive, since him was hired somehow. He after started working with the team, him complaining about the project proposal, about the bad code decisions and had serious discussions with the product owner. After I talked with the PO, I opened a meeting with the complainer to extend my hand and say that I was opened to listen, him thanks me but preferred to stay a little away. The CTO proposed that since him spotted a bad code (it really was), him had time to analyze better and fix! In the end him lost 2 or 3 weeks fixing the code, wasn't able to finish and request resignation directly to the HR with the reason that the team and the project was bad, probably criticized the CTO. I had to take the code him left and finish the fix!
brunoarueira··on When Your Exit Strategy Dream Is My Customer Nightmare
The worst experience for me is changing directors/C-level to maximize the exit profit, between the lines of "disagreements over company policy" can be many things, but one major pain is culture changes which drives down everything, once the company stimulating the healthy place and then creates a disturbed one where we can't grow and deliver our better solutions only for money.
brunoarueira··on China Dominates 44% of Visible Fishing Activity Worldwide
Taxes isn't the right approach, in Brazil is taxes over taxes and the poor people is the real affected by them. They cannot eat fish frequently or only through processed food, which in turn, is mixed with many other things which are bad for their healthy too.
