Location: Brazil

Remote: Yes (US time zones preferred)

Willing to relocate: No

Technologies: C/C++, Embedded Linux (Yocto, RT), Zephyr, Qt, Python, Typescript, AWS, Elixir/Phoenix

Résumé/CV: https://www.linkedin.com/in/jonas-dourado/

Email: jonas.jonaias (at) gmail.com

I am a Software/Firmware Engineer with 14+ years of experience bridging the gap between hardware constraints and user experience. I specialize in system optimization, embedded systems (bare-metal to Linux), and scalable backends.

Highlights:

- Firmware: Yocto, Zephyr, Linux, FreeRTOS, BLE, DSP, ARM/MIPS/x86.

- Backend/Infra: AWS (CloudFormation, IoT), Elixir/Phoenix, CI/CD pipelines.

- Recent impact: Owned the full audio pipeline at Limitless AI (from firmware audio codec to backend storage) and optimized audio playback latency to <800 ms at p99. At R-Zero, reduced the firmware flashing step by 10 minutes per unit on the manufacturing line.

- Experience: Limitless AI (Wearable), SunPower (Energy), and R-Zero (IoT Health).

Comfortable owning the stack end-to-end—from low-level drivers and real-time firmware to backend ingestion, cloud services, and operations. Strong recommendations available from leads at my last 3 projects.

Open to consulting or full-time. Happy to hop on a call to review your architecture or discuss optimization bottlenecks.

> They never reveal their core intentions.

Is it so hard for them to say, FU, office time now because I like it, or because we want to force attrition, or we bought all this RE and by god we are going to use it?

I mean, if they give the honest non vibe reasons, it would be the same, but at least honest.

Wall Street doesn't care as long as the stock goes up.

Customers don't care as long as they get the product.

And employees can't do anything other than vote with their feet.

So what's the downside of being honest?

Not a "promotion deal" - that's way too strong a term, plus it feels ickily corporate. Who wants a "promotion deal"? Yuck.

But yes, we are in touch with the Hack Club people and are delighted to help turn some of the amazing creative work their kids are coming up with into decent Show HNs. I'm sure everyone can agree that a project like this one deserves some support:

Show HN: MyraOS – My 32-bit operating system in C and ASM (Hack Club project) - https://news.ycombinator.com/item?id=45715055 - Oct 2025 (55 comments)

There's no guarantee anything will "go viral" of course—that's up to the community. But we're happy to help the creators do their writeups in a way that fits HN's conventions. HN can be inscrutable to outsiders, and kids are by definition outsiders since they haven't been around for years to absorb the vibes.

(and btw, the same goes for any student or young person working on a project that the HN community might find cool and enjoy discussing)

The biggest problem with mozilla is they are trend chasing instead of finding a niche.

The AI stuff is the perfect example. Are there people who like AI? Certainly. Will they use firefox? Probably not.

At this stage firefox is the anti-establishment choice. That crowd hates AI. Betting on AI might make sense if you are chrome. It doesn't make sense if you are firefox.

Many executive jobs are little more than “being in the office” - they have to “go to work”. This leads them to think presence = work being done - they don’t know what actual work or productivity is. If they don’t have people present to lord over then their job starts to be seen for what it really is… a suit and tie in an office and nodding while saying “hmm” at meetings.

I am not sure that it matters; you can already remap the keyboard and mouse in X windows, and if it helps to design input devices differently for left-handed people, then that would be managed by someone else.

However, if they add the possibility to use touch-screens (although I don't like touch-screens, some people might want to use it), then considering being left-handed vs right-handed might potentially be significant when designing a GUI library or a GUI program, although even then it is not certain that it will.

Still, if something does affect the users in this way (with accessibility, which involves other things too; and accessibility is not only for people with the relevant disabilities, but is for everyone (including people with those disabilities)), then it is true that having people who use those accessibility features (and whatever other features you might add or change, even if they are not accessibility features) in the testing team is helpful, so yes, that is a case. However, it is FOSS and does not necessarily need a dedicated team for testing. They do say anyone who wants to and is able to work on it is allowed to do so, so if someone is concerned with this then hopefully they can help, too.
Ask HN: Recruiters, does contractor vs. FTE matter?
by salt-thrower | 2025-12-02 03:32:24+00:00
I'm wondering if recruiters are more likely to pass on job applicants who are currently in contract roles, as opposed to applicants who are currently in full time salaried roles.

I know the job market is more competitive now, but I noticed I'm getting fewer responses on job applications than I used to, even a couple years ago. I worry it's because my current gig is a contract role at a boring company that does not scream "high value tech worker here."

Some people assume contract gigs are easier to get and are worse jobs in general, so people with better options don't take them. And to be honest, that's sometimes true. I'm in my current situation because of how tight the job market got the last couple years and now I'm afraid that I'm stuck.

Is there any merit to this or am I just being paranoid? Are recruiters more likely to see "contract" on a resume and toss it in the bin?

I appreciate your candor.

And yes, I agree. On multiple occasions in my adult life, I've "proved" my citizenship under threat of perjury, but that is only to say: I've made a statement on a form with my signature on it. My word alone was ~enough.

But to get a Real ID, my word alone isn't adequate: I have to prove my citizenship by presenting documentation.

In my home state of Ohio, that proof requires me to show up at the BMV and provide documentation[1] showing five different elements:

1 - Full Legal Name

2 - Date of Birth

3 - Legal Presence in US

4 - Social Security Number;

5 - Ohio Street Address

...and most of this is easy-enough.

But element 3, legal presence, is a bit tougher. There's a number of documents that are accepted, but only one of them is applicable to a plain-Jane native-born-Ohioan who does not have a passport.

That document is an original birth certificate, or a certified copy of one.

I don't have that. I have a copy, but it's just a copy. It is a copy that was made by the city's Health Department and it is on the fancy green cardstock they use, but it's still just a copy and this just-a-copy is not a certified copy. (I know this, because when I got that copy decades ago to join the military, they asked if I wanted a certified copy at extra expense and I said "No." This not-certified copy that I have was plenty good-enough to enlist, serve, and get paid in the US Armed Forces -- but it's not good enough for a Real ID. My original DD214 is also not good enough.)

Accordingly, I'll have to make a trip to my hometown and again pay them some money for a copy, with some extra money on top for whatever it is that it means for that copy to be "certified."

And then, I'll be able to go to the BMV and pay them more money too, and get a new ID mailed to me eventually that will re-enable me to fly on domestic commercial flights without fuckery.

(It's all rather amazing to me.)

Open source software is not the best argument for distributed teams when you need to iterate fast.

Hell, I had commit rights to a popular open source “AWS Solution” when I was there and it took so long to get something approved to be pushed into the mainline that I ended up forking it for individual customers (AWS ProServe) and then eventually getting most of it merged back in later.

Now that I’m not at AWS, even though I know the team there, I doubt I could get something approved to merge back in even though I was the third highest contributor to the project for awhile.

Is the solution to sycophancy just a very good clever prompt that forces logical reasoning? Do we want our LLMs to be scientifically accurate or truthful or be creative and exploratory in nature? Fuzzy systems like LLMs will always have these kinds of tradeoffs and there should be a better UI and accessible "traits" (devil's advocate, therapist, expert doctor, finance advisor) that one can invoke.

Owning is only more expensive than renting if depreciation + interest + maintenance exceeds rent. And in most US cities, depreciation is negative in the long run.

Lots of advantages to owning and having a mortgage too: deduct mortgage interest from taxes, use equity as a line of credit, you can actually make substantial changes to your living space, and so on.

Former Dendrite user: Yes and no. Mautrix stuff does work with Dendrite, technically, but only partially. For Mautrix-Discord, I was able to get DMs mostly working, but only DMs: bridging servers just never really worked at all. I'm honestly not 100% sure why this is the case, but it's not worth worrying about Dendrite anymore. It is a dead-end server that never worked very well. Up until shortly before it was discontinued, none of the Mautrix bridges worked well enough to actually use.

> but try to consider these groups: older people who will not learn precise right hand movement anymore, people with temporary or permanent right hand injury, people with no right hand, people with missing right hand fingers, etc.

Perhaps, but that does not seem to be a software issue, at least, not a software issue with the X window system itself. If you want to consider such things, it is probably more important if someone who is concerned about such things wants to design hardware specifically for such people.

Allowing you as long as you want to type something instead of adding a time limit can be helpful for such people (since having less fingers or only one hand might make it take longer to type) but it can also be helpful for any other people for whatever reason (e.g. you have to answer the telephone before continuing to type on the computer, etc).

Accessibility features are for everyone.

>unfair to place all the blame on the individual.

I'm mostly blaming the rich.

>everyone in the USA is responsible for the atrocities the USA war industry has inflicted all over the world.

Yeah we kind of are. So many chances to learn and push to reverse policy. Yet look how we voted.

>sometimes you just have to do what you have to do, and one of those things is pay your taxes.

If it's between being homeless and joining ICE... I'd rather inflict the pain on myself than others. There are stances I will take, even of AI isn't the "line" for me personally. (But in not gonna optimize my portfolio towards that either).

Huh, the link now points to an article titled:

> "Why worries about American job losses are overstated."

Instead of the archived version.

While the beginning of the article is the same, the last line in the preview differs:

> Original: "...to support a weakening jobs market."

> New: "...to support a weakening jobs market. Look closer, however, and much of the gloom seems to be overdone."

Though I don't have a subscription to check the rest of the article.

Moralizing through whataboutism does not logically follow in disproving the China threat narrative, it is axiomatic that what matters is what they are doing to us, not what we are doing to them from that vantage.

Rather, I'd say it speaks more about how deranged the post-snowden/anti-neocon figures have become, from critiquing creeping authoritarianism to functionality acting at the behest of an even more authoritarian regime. The funny thing is that behavior of deflection, moralizing and whataboutism is exactly the kind of behavior nationalists employ, not addressing arguments head on like the so-called "American nationalists".

I think we have the exactly same problem with the Dell laptop. Anyway after reading through all comments I figured it is unlikely buy a Dell laptop, and less likely to buy a refurbished one as they only carry a 1-year warranty max (one year for 49 CAD and 100 days for free).

And yeah my 470S is still pretty strong. I started to use it again for my side projects.

I kinda wish I could find a contracting job, so that I can buy an expensive laptop and expense it as cost, and my wife won't cast an angry look towards me, lol.

you have to show this 'future-illegal' action is harmful first by demonstrating harm.

That's why i used the sugar example - it's starting to be demonstrably harmful in large quantities that are being used.

I am against preventative "harmful" laws, when harm hasn't been demonstrated, as it restricts freedom, adds red tape to innovation, and stifles startups from exploring the space of possibilities.

Specifically, reverse math (a subset of metamathematics which looks at swapping axioms and theorems) allows us to show that some hard problems are equivalent to each other.

EDIT: I think this line is the most telling:

> But he cautioned that the reverse mathematics approach may be most useful for revealing new connections between theorems that researchers have already proved. "It doesn’t tell us much, as far as we can say, about the complexity of statements which we do not know how to prove."

So, at this point, it helps us understand more about problems we already understand a little about, but nothing yet about new problems.

Prosecutor, judge and jury? You have access to their minds to know their true intentions? This whole “deepseek is controlled by CCP” is ridiculous. If you want to know how bad the CCP is at IT, then check the government backed banks.

The way I see this, some tech teams in China have figured out that training and tuning LLMs is not that expensive after all and they can do it at a fraction of the cost. So they are doing it to enter a market previously dominated by US only players.

> Some prominent economists and industry executives have recently cast doubt on whether renewables will ever be cheaper in places like Germany and the U.K. that aren’t blessed with abundant sunshine and have bet big on wind. Onshore wind turbines in Germany produce around one-fifth of their total theoretical output. Solar panels in Germany and the U.K. use only around 10% of their total theoretical output.

Are you sure? I seem to remember people getting burned for publicly disclosing security vulnerabilities after stubborn agencies refused to fix them for years. Stuff like, exposing thousands of SSNs through a public gateway... We are literally having this discussion on URLs because of famous cases where people DID face unfair treatment. I don't recall any actual fix for this legal chicanery either. If you do, I would be very interested.

Voting is a good start. Not just in nationals but look at local policy. So much of this is bottom up.we got into this by voting against oir best interests for at best liars and at worst blatant crooks.

Past that, simply look at the small actions on your life. These build and define your overall character. It's hard to vote for collective bargaining of you have trouble complimenting your family at the table. You need to appreciate and feel a part of a community to really come together.

This all sounds like mumbo jumbo on the outside, but just take some time to reflect a bit. People don't wake up one day and simply think "you know, this really is all the immigrant's fault". That's a result of months or year of mindset.

It must be exhausting and stressful being an OS dev or dev team. I haven't experienced any of the troubles that are referenced here; and, the one complaint I've had over the years was resolved, like, on the very next update.

I use my mac for IntelliJ and Firefox. I guess maybe my usage surface is just really, really small; but I basically never have any problems ... and then others come along and say they're having huge issues.

I see the various updates as they happen and like ... all of them are neutral or minor inconveniences that are resolved next patch, for me.

Yeah this latest generation of models (Opus 4.5 GPT 5.1 and Gemini Pro 3) are the biggest breakthrough since gpt-4o in my mind.

Before it felt like they were good for very specific usecases and common frameworks (Python and nextjs) but still made tons of mistakes constantly.

Now they work with novel frameworks and are very good at correcting themselves using linting errors, debugging themselves by reading files and querying databases and these models are affordable enough for many different usecases.

Jeez, the keyboards!

OK we probably have different preferences, but I really hate:

1. Arrow keys have different sizes

2. page up/down right up arrow keys (very easy to touch those accidentally)

So far I really love the Macbook Pro layout. I wonder why no one tried to copy it, considering they tried to copy everything else.

Around 2006 or 2007, I was working on the Sage Notebook. I did a little JavaScript injection, and managed to make the notebook execute JavaScript instead of sending Python code to the server and printing the result. Lo and behold, I could interact with my JavaScript environment on any browser we supported (ie, ff, safari and Opera). I don't recall if firefox had its JavaScript console yet but it was a game changer on those other browsers.
by dididn284d | 2025-12-02 03:45:13+00:00
that’s the ambiguity that I think is tripping the discussion up a little. Also the idea of a CLI/Shell/Terminal is also quite coupled to a system, rather than services. Hence the whole ‘web service’ hope to normalise remote APIs that if you squint hard enough become ‘curl’ on the command line

But the point is none of that is intrinsic or interesting to the underlying idea, it’s just of annoying practical relevance to interfacing with APIs today
Show HN: Watsn.ai – Scarily accurate lie detector
by flx1012 | 2025-12-02 03:46:40+00:00
No signup required—just upload or record a video to verify its truthfulness. You can test it on anyone: internet clips, your significant other, or even yourself.

I know there are tons of scammy 'lie detector' apps out there, but I built this using SOTA multimodal models in hopes of creating a genuine breakthrough in the space. It analyzes micro-expressions, voice patterns, and context. In my own testing (over 50 trials), it reached about 85% accuracy, which honestly felt a bit scary.

It’s also fun to test on famous YouTube clips (like Obama talking about UFOs). I’d love to hear what you think and will be improving Watsn.ai every day based on your feedback!

> Do you have non-ACA insurance? One explanation for why your costs are so much higher than the national average is that you're on a non-complying plan (you can also still buy plans that will exclude preexisting conditions --- they just can't be sold on the ACA marketplace). I'm pretty confident KFF isn't making these numbers up.

You kid, but you might be onto something.

The majority of users are content with chromebooks, what does that tell you about the requirements of desktop computers today? It tells me that they are just niche professional tools; and professional tools largely suck for UX..

I had an interesting realisation the other day (that's tangentially related): on my iPhone and iPad: I can't access my work emails or chats at all. Yet on my significantly more difficult to secure laptops: no problem.

The mobile platforms have built-in mechanisms for remote attestation. Desktop operating systems do not.

I think as soon as companies realise that an iPad is "good enough" for email/excel/word workers, we'll see an even more precipitous decline of the desktop operating system experience.

> They’ve never not been like this.

If you only look at their earlier 10.x.0 releases this is true.

But it was well known that you don’t upgrade to a new macOS on any non experimental system until the 10.x.1 release.

In the past (until the mid 2010s I think), if you upgraded to 10.x.1 you’d have a very smooth experience.

My 17 y/o self (living in small-town Oklahoma) lusted heavily after this car. For a few weeks, I would drive down to the dealership in my parent's car in order to drool over it in person (yeah, I was stupid kid who loved this car). Anyway, one day I managed to convince a salesman, who wasn't much older than me and obviously bored, to take a test drive in one. We got into the car and he told me that he first was going to show me what the car could do before letting me drive it and so, I had to wear the seatbelt (which was unheard of back then). Soon, we were on the highway and he put it through its paces - demonstrating the acceleration and handling, but he got a bit overconfident and then wound up putting it into a spin. By an extreme amount of luck we managed to avoid hitting anything. After he regained control we pulled over to the side of the road to inspect the car, and much to our relief (and astonishment on my part), there wasn't any visible damage on it. To his credit, he let me drive it back to the dealership were I shook his hand and thanked him for not killing us. Just as I get over to my mom's car, the sales manager shows up to try to close the deal - but when he got a look at my 16 y/o self, his demeanor changed from optimism to mild disappointment. I said I had to discuss with my father before I could consider buying it (but the look he had on his face was that he knew I was full of crap)
