Two quick examples that I can think from the recent past - I work in a fairly tech conservative IT environment for mid-size industrial company. We're slow to adopt lot of industry trends. So when containers became popular in the mid-2010s, we pretty much stayed away until around 2020-2021. I've been running containers in my home lab for years and had a very grasp of building and deploying containers. So I was able to drive that change and also pass on that self-gained knowledge to many on team that were to new to the concept.

Another example - for years we were mostly a Oracle shop. With some SQL Server thrown in. But management wanted us to trim our annual licensing cost. So we switched a lot of our in-house applications to Postgres. I was using Postgres for years at home and had gained a lot of experience with it. So again, it was an area I was able to contribute a lot when transitioning away Oracle and Sql server.

On the flip side there are things I learned at work, that I was able to bring home and apply to my home lab. One being Ansible and other being network segmentation. Specifically around using VLANs and access control
Show HN: Aiko – Easiest way to manage MCP configurations and credentials (Beta)
by willahmad | 2025-07-27 22:24:41+00:00
Hey HN,

I'm building Aiko, an AI tools marketplace that solves the headaches of managing MCP (Model Context Protocol) configurations and credentials.

After working with and building many MCP servers, I kept running into the same frustrating issues:

- Managing multiple environments (production vs development) meant either duplicate server configs or constantly updating API keys

- Too many enabled tools either hit context limits or caused LLMs to hallucinate when choosing the right tool

- MCP servers often expose dozens of tools, but I only wanted a subset and had to configure this separately for Claude, Cursor, and every other AI assistant

- Most MCP aggregators are third-party hosted, which meant sharing sensitive credentials with external services

Aiko addresses these problems by providing a centralized way to manage your MCP configurations, credentials, and tool selections. You can easily switch between environments (profile management), selectively enable/disable tools globally, and all your credentials are encrypted (with MacOS Keychain) and stored locally.

I've also added some interesting MCP servers as part of this marketplace, including one that converts any OpenAPI v3 spec into an MCP server with full authentication support ().

The platform is still in beta, and I'm actively working on expanding the tool marketplace. Some features like Gmail and Calendar integrations are currently under security assessment but you can see them in action in the demo video.

Would love to get feedback from the HN community, especially from others who've been wrestling with MCP management!

The other reploies seem to have answered it! I've never understood why iOS allows JIT inside WKWebView yet not inside bare JavaScriptCore. Maybe because WKWebView runs in its own separate process while a JavaScriptCore instance would run in-process? As for Android, guess Google are just a little more gung-ho?

> thanks for the article. these days it's rare to see something so well researched and written while still being able to tell it was authored by a human. cheers

Really appreciated, thanks! I do despaire that the ease of generating content with AI disincentivises (and discourages) authors from expending real effort, but there's a satisfying inflection point at which you can be sure you've written something that an LLM couldn't possibly have come up with.

Nex is a cybersecurity student in a house of similar people, they're gonna take every way :3

> The plan is, in future, since we can't hack something that doesn't have a brain, to instead attach a brain to it. The dishwasher is easy, we can just whack that on a smart plug and monitor when the power use surges and drops. The dryer is a bit more difficult, since they pull a LOT of power, and smart plugs typically either don't support that much power, or are incredibly expensive. So that's likely going to be some fancy vibration sensor-based thingy

That's it, it's life phase makes focus impossible, and coding is a massive drug when you're in the zone. And I was very very good a few years ago when in the zone working on highly concurrent (and distributed) systems. I felt like superman compared to everyone else I worked with as I could build things no-one else could.

There are plenty of people on this site who must be able to relate to that (and who are much better than I am - I was a Championship player playing for a League Two club and there are Galactico's active here).

That's long gone and now I'm turning into Eddy Howe (a football manager) not Steve Bull (who was an excellent striker who played for Wolves his entire career in the lower leagues but really should have moved to a good club because he was too good for them).

I wonder sometimes if that's the hump that top class sports stars have to go through when they retire from playing, it took me a few years to understand and accept.

"I’ve always found the idea of “restoring” ecosystems a bit philosophically tricky."

Me too, however I think that making an ecosystem functional, rather than dysfunctional is the goal, rather than actual restoration to a nominal "correct".

The thing is that diversity, fecundity and like measures are really important when it comes to ecology, not historical accuracy - that's for aircraft museums.

> a way of hitting back at "the elites" who have the temerity to call GOP politicians and donors out for their lies and bad behavior

True for academic institutions. No evidence this is the motivation at NASA. Simpler: science costs money and leadership believes that money is better spent giving folks like me a tax cut than paying for poor folks' healthcare or basic research.

Fortunately, it looks like Beijing is ready to pick up the torch [1].

I've been making songbooks for my favourite songs. I am currently working on a songbook for some friends. I've found https://www.chordpro.org/ an amazing CLI tool, under active development. I am using the ukulele, but the program also easily can do guitar or piano. The program reads a bunch of text files and produces a really nice PDF. I've also used pandoc + LaTeX for the front matter.

Are you seriously asking, or is this one of those sarcastic rhetorical questions? The point of all of these studies is that society has deemed women shall be paid less. You asked about models, but it is also prevalent in acting as well. A leading female actor will be paid less than a male actor in a similar role. It gets tricky here regarding the perceived attraction/recognition to the audience, but it does seem to default to male actors being paid more as the default.

You can ask why till the cows come home, but there will never be a satisfactory answer. Just asking the question to imply wrongness does not really do anything though.

Hey, blog author here. It only had access to the internet for a brief second, and even then it was on an entirely separate network because of how I just set up my openwrt router as a client to the main network. Our guest network is completely isolated, an explicit firewall rule had to be added so that my script could communicate with the washer while it's on this network. It has no access to anything but itself, and occasionally hears the screams of my script demanding it serves up data.

It has access to nothing, only my script has access to it - I don't see a risk here. I still have the heebie jeebies knowing it's connected to anything at all, or even the fact that it can do that, but also spending a night hacking a washing machine was incredibly funny to me and totally worth it. Plus, got some useful notifications out of it.

No idea! The only benchmarks I'm aware of for QuickJS are against other JavaScript engines (https://bellard.org/quickjs/bench.html).

That said, one thing I've heard a lot from NativeScript TSC members building on top of QuickJS is that QuickJS has staggeringly low overhead for calling C functions. In fact, I was shown benchmarks in which it calls native functions faster than JS functions (perhaps it's easier to optimise because JS functions have complications like closure capture to worry about). I imagine this has conceptual overlap with how V8's Fast API works.

Curious Yellow, anyone?

https://en.wikipedia.org/wiki/Glasshouse_(novel)

> "Curious Yellow is a design study for a really scary worm: one that uses algorithms developed for peer-to-peer file sharing networks to intelligently distribute countermeasures and resist attempts to decontaminate the infected network".

Hat tip to HN user cstross (as I discovered the idea via Charlie’s blog):

http://www.antipope.org/charlie/blog-archive/October_2002.ht...

These topics were first brought to my attention through his amazing novel Glasshouse. I’ve had the pleasure of having my first edition copy of the book signed by the author, and I then promptly loaned it indefinitely to a friend, who then misplaced it. The man himself is a friendly curmudgeon who I am happy to have met, and I have enjoyed reading about the future through his insights into the past and present.

Also I must acknowledge Brandon Wiley, who wrote the inspiration for Curious Yellow as far as I can tell.

There's more to life than "innovation", but what you say tracks, I was part of an organization that became extremely innovative but went bust in the process.

Which is amazing for earth-orbit commercial launches, but doesn't move the needle for the many other things NASA concerns itself with, like research as mentioned elsewhere.

Show HN: Vid2gif – Convert .mp4/.mov to optimized GIFs locally using FFmpeg

As I worked on my personal projects, I kept running into the same problem: There wasn’t a simple, local way to convert screen recordings into GIFs that look clean in a README.md.

Recordings don’t render inline on GitHub READMEs, and I didn’t want to rely on bulky video editors or upload my files to some sketchy ad-filled site. So, I wrote a small script.

I found myself using it so often that I turned it into a proper tool: minimal, local, and built for developers who care about good documentation.

I’m not some elite hacker — just a dev who wanted a better way to share demos. Thought others might find it useful too.

I kind of disagree in that the giving him a platform is just the cover for the actual purpose which is a way for anyone to shovel him money through a "legitimate" means to avoid any sense of bribe or quid pro quo. Very similar into how certain countries that wanted to curry favor made long term rental agreements for property owned by Trump. It was only slightly less obvious than dropping of bags in the oval office with $ marked on them.

Thanks for answering!

>tl;dr is that the desktop app (including remote SSH sessions) is free to use with a permissive license (no account needed, no subscription, commercial use is OK, etc), but using Positron in a server mode does require a paid subscription.

I feel the FAQ would've been better off with this as an answer to a separate question ("Is Positron really free?").

First, this information is hard to infer from the text you have there.

Second, I wouldn't wouldn't know to look for this information in a question about the server mode. I don't know what it is before I look deeply into your product!

Before that, I want to know what is actually free about this platform, and what isn't. Then I can learn what the server mode is.

I’m building something new, something I haven’t seen anyone in the field attempt yet.

Most of what we see today are No-Code platforms. They promise simplicity with visual interfaces, but let’s be honest: if you’re an expert, do you really want to build with drag-and-drop? These tools have their place, but they’re often limiting, not empowering.

We need a standard way to define agents - one that fits into your existing workflow: Git, your programming language, and real version control. Because let's face it, those tools are not going anywhere - they are here to stay!

Introducing Agent Definition Language (ADL).

Think Swagger for agents. Think GitOps for automation.

With ADL, agents can build other agents. It’s inspired by Google’s A2A protocol, but adds language-specific code generation. The goal? Make agents easy to define, share, and deploy - without being locked into a specific platform or a vendor.

Open source Currently supports Golang Contributors are needed https://lnkd.in/d3muxtBf Example code: https://lnkd.in/dbF74xZk

Let’s stop chasing platforms. Let’s build real, production-grade agents. If you’re working on something similar, let’s connect. There are only so many hard problems, let’s solve them together.

I'll be allowing people to generate the code targeting a specific platform - as an example.

You're working with Github and need a CI - just pass the cli --ci You're working with serverless and need to deploy your agent to something like CloudRun pass the codegen --cd-cloudrun

This is just as an idea.

I've already developed a CLI that generates the Golang code.

More insights coming soon.

No. There's a *big* difference between the load limit printed on something and it's true expected failure point. As somebody could be hurt by the chair failing I would expect the real strength to be in the ballpark of 3,000 pounds or even more. Figuring the permissible % of expected yield point is handled by the engineers, normally not by the end users.

Load ratings near the failure point are only done when the failure will not cause a problem, or when the failure is actually a desirable property (breakaway tethers of various types.)

You don't have to jump. Not all progress goes forwards. As anyone who's familiar with web frameworks and crypto knows, most of the paths lead to dead ends.

Play with things. Treat them as a toy, not as homework. Eventually you'll get a feel for what is useful and what is someone trying to sell you something.

The first time I actually got something from a MCP was when I just asked claude to check my emails for anything I need to act on. I had 8 emails in the inbox, didn't expect it to find anything. But it found an important request from accounting that was cc-ed and forwarded multiple times to the point I didn't see the actual ask. It was also some tedious bureaucratic stuff so Claude write the response to it in 2 minutes and I didn't have to procrastinate on it the whole morning.

> These are called "balloon"

And are not interactive as far as I know. I've not seen a way to get a balloon on the type in another balloon and then go to the browser docs from a link in that.

> Do you mean something like this?

Yes, but that's still restricted to terminal characters (you could probably do something fancy with sixel, but still) - for larger files with big indents it's not useful anymore.

> contextual buttons on a line of code

For example options to refactor based on the current location. I could construct this manually from 3 different pieces, but this exists in other IDEs already integrated and configured by default. Basically where's the "extract this as named constant", "rename this type across the project" and others that I don't have to implement from scratch.

WinterCG is trying to help standardize web APIs to address these concerns. So one strategy when writing server-side js is to stick to standard APIs as much as possible.

If you do want to leverage runtime-specific code you can isolate that code in separate modules, so if you ever do need to migrate off a particular runtime it's easier to identify/replace that code.

Ultimately it's all JavaScript, and since most of these runtimes are open source even if they're abandoned we might see community forks. Though even if your chosen runtime is completely without support, I don't see a migration off being an extremely urgent or difficult task for most projects.

>However, I looked through all the posts you just linked. I still have nothing quantitative on whether "PWAs never took off". It's so much analysis on Apple.

"Nothing quantitative"? You either dont know what that word means or you're unable to grasp what you're reading. I've explained in great detail why PWAs couldn't live up to their potential. The reason why there is "so much analysis on Apple" is because they, as a dominant gatekeeper, have actively engaged in sabotage of PWAs in defense of their App Store by treating PWAs as an existential threat. (See? You're making me repeat myself again, because you either refuse to reflect on what you're actually reading or you are simply not able to connect the dots and realize that i've already answered your question)

>> That's just the lazy manufactured and false narrative that I've already thoroughly debunked. I'm not going to repeat it, since you would just ignore it again.

>This is how you replied to me. You say "ignore it again" but this is the first time we spoke and all I can see is up-thread. That's what I mean by prejudice.

I said that "you would ignore it again" (which you have just done btw) precisely because that's not the "first time we spoke", your comment was in response to my comment and that comment of mine already explained that Apple sabotaged PWAs. You simply ignored that and baselessly claimed that "PWAs 'just' didn't take off" with no effort to substantiate your claim whatsoever. So it's not me being "prejudiced", it's an objective prediction based on your behavior which you have just proven, my prediction was spot on.

Perhaps that is the real danger. Everyone except a small elite who (rightly) feel they understand how LLMs work would simply give up serious thinking and accept whatever "majority" opinion is in their little social media bubble. We wouldn't have the patience to really engage with genuinely different viewpoints any more.

I recall some Chinese language discussion about the experience of studying abroad in the Anglophone world in the early 20th century and the early 21st century. Paradoxically, even if you are a university student, it may now be harder to break out of the bubble and make friends with non-Chinese/East Asians than before. In the early 20th century, you'd probably be one of the few non-White students and had to break out of your comfort zone. Now if you are Chinese, there'd be people from a similar background virtually anywhere you study in the West, and it is almost unnatural to make a deliberate effort to break out of that.

Nope not at all. The first ~10 years were as a kid, so not professionally. Professionally I'm at the top of my niche and decided to work as a consultant instead of starting doing my own startup or starting an agency as I wasn't able to commit and have a family, and I loved writing code (and was bloody good at it, and at making my teams much much better by leading by example & helping them grow).

I spent the pandemic being one of the key players in the pandemic response, writing a lot of code but also helping a load of teams over different countries collaborate, and anything else I could do to make everything work. Oh and bringing up kids at the same time.

Now I'm at a startup, finally, and getting the engineering team off of the ground. Still trying to code (it's really hard to give up chasing the highs) a bit but there's less time for it and no time for the really hard deep dives (and I'm not willing to ignore my family to no-life it as others can do).

With that context, yeah, it's not as enjoyable. Sure I could try and transition back to a full-time coding roll and yeah, I'd be working on fun puzzles and enjoying it, but that means my impact is more limited. It's a better use of my skills + experience to be doing what I'm doing. Pays more too but both pay well :-)
