Show HN: Cloudavenue.ai – Prevent breaking your data stack with a GitHub app
Hey all!

We built CloudAvenue.ai - LLM-based GitHub app that helps data teams avoid making breaking changes in their data stack.

Try it out - no signup required.

With CloudAvenue.ai, you can:
- Catch errors before they hit production
- Generate detailed impact report for every change
- Improve data pipeline integrity
- Drastically reduce troubleshooting time

Here's how to try it:

1. Visit https://www.cloudavenue.ai or by directly installing our GitHub app - https://github.com/apps/cloud-avenue-data-stack-insights

2. Follow the instructions to connect your GitHub repos.

3. Make some code changes and see how CloudAvenue.ai provides real-time feedback.

4. [OPTIONAL] create CloudAvenue account to connect non-repo tools, e.g. Fivetran, Lightdash, etc…

We're excited to share CloudAvenue.ai with the Hacker News community and get your feedback! We’re also happy to add support for more tools and technologies - just let us know which ones you’d like to see next!
That ban is imaginary. It never existed. Many people decided to use other terms at their free will and others didn't. Both terms can be still found in plenty of projects.
P.S.: I just ran across a not-so-charitable version.

Going through new items, I noticed someone [flagged] this submission, but I read it, vouched for it, and even left a detailed explanation... But now I see it's gone to [flagged][dead] anyway, presumably because it happened to have certain words in the title.

https://news.ycombinator.com/item?id=42937533

Edit: So, I noticed it's resurrected again, so... thanks? That wasn't my intent linking it here, I just think it's a good "tracer bullet" for discussing moderation, an example that attracts false-positives.
Cool. Now address the fact that all of this is an unconstitutional coup.
That’s what programming languages are: You define a context, then you see that you can shorten the notation to symbol character: Like “The symbol a will refer to the value of type string and content ‘abcd’ and cannot refer to anything else for its life time” get you:

const a = “abcd”

That is called semantics. Programming is mostly fitting the vagueness inherent to natural languages to the precise context of the programming language.
Similar flow but much better user experience. At least that is how I’d describe it.
I think it depends heavily on the people. I've done pair programming at a previous job and I hated it. It wound up being a lot slower overall.

For me, there's

- Time when I want to discuss the approach and/or code to something (someone being there is a requirement)

- Time when I want to rubber duck, and put things to words (someone being there doesn't hurt, but it doesn't help)

- Time when I want to write code that implements things, which may be based on the output of one of the above

That last bucket of time is generally greatly hampered by having someone else there and needing to interact with them. Being able to separate them (having people there for the first one or two, but not the third) is, for me, optimal.

Maybe those racists should have gotten together, forget their minor differences, and commit even more atrocious acts since folks these days think they were all baddies (and white, the worst thing of them all!) anyway. The wars they fought were completely pointless.

If only there was someone to tell them that all whites are really the same, so they would have understood. Well, Hitler had some ideas of unity close to that (with idiotic things like excluding "those stupid eastern slavs"). Modern racists see nothing but the skin colour, they don't even bother measuring your skull. That's how bad things have gotten.
21st Century C++
You can do that without pair programming, though. Both through actual discussions and through rubber ducking.
> Tbh the reason I don't use LLM assistants is because they suck at the "low level". They are okay at mid level and better at high level. I find it's actual coding very mediocre and fraught with errors.

That's interesting. I found assistants like Copilot fairly good at low level code, assuming you direct it well.
This is the stupidest thing I have ever read on Hacker News.
Lately I just cant get the thought out of my head that 69% of Americans either directly or tacitly approved Trump's agenda.

A big chunk of those people now voicing concerns did not vote to prevent the course we are now on because "both sides are the same," or variations of that demonstrable falsehood.
As is Rust. And the C++ compiler performance improvements in LLVM apply to Rust.
> Why? You know you are not going to use X. The only benefit you could get from learning about Debian’s change of policy is only the dubious pleasure of having your preexisting beliefs validated.

No, I appreciate learning their stance on it because now I know they do actually stand by the values that are posted on their website, and I know that I won’t need to be looking for an alternative Linux distribution.

> Debian is not making this announcement to everyone,

Yes, they are. Posting only to Twitter would reach a smaller audience. Or are you saying that the average Twitter user doesn’t know/care to surf the web?

> This is a very low and cheap way to get appreciation

How so?

> and only worsens the politicization and polarization of the issue.

Human rights are not a political issue, and a site that is run by, staffed by, and platforms people who wish to take away human rights should be shunned, loudly and often.

Are you saying downvoting is not the correct response to ragebait? Seems to me that's what it's for. If not, your phrasing is confusing.
If you look at polls of physicists over the past few decades, many believed that Von Neumann's proof ruled out all hidden variable theories. This was wrong. Many others also believed that Bell's theorem ruled out hidden variable theories. This was also wrong, and Bell himself was actually a fan of Bohmian mechanics, which is a non-local hidden variable theory, and one of his motivations for deriving his famous theorem.

All of this is to say that being a physicist doesn't make you an expert in quantum foundations. Neither am I, but I've read a diversity of literature from experts that work on quantum foundations, so I am aware of the range of misconceptions on this.

This assumption, that everyone upset about these actions voted for them, is only half the fallacy. The corollary and equally mistaken assumption is that people who voted for them are upset about the actions.

Plenty of people are happy about the actions because it’s exactly what they voted for – “promises made, promises kept.” This isn’t implementing some secret agenda without warning; it’s a fulfillment of a central campaign promise.

I disagree. "The algorithm" is understood by everyone in 2025 to be a more-or-less perfect attention hoarder. TikTok, Insta, YouTube, etc. have proven they can definitely surface the content that users will like. I see no reason why profiles would be different.
It’s kind of lame that these guys are blacklisting words based on some master list. Normally these things get grandfathered in but I guess they’re just blindly following orders after getting sold down the river. It seems like an insane waste of manpower if you ask me. I’d hate to be the low man on the totem pole slaving away at this kind of bitchwork and getting ragged on by the bossman if I missed a word.
Doing it in your native language can add an extra dimension to it, though. In a way, I would consider it like double checking your work on something like a math problem by solving it a different way. By having to express the problem and solution in clear language, it can really help you make sure your solution is a good one, and considers all the angles.
Indeed, we donate to several open source projects on which we depend, but we're also a small two-person operation. No medium/large company I've worked for ever donated monetarily to open source projects, though one did encourage us to fix bugs and submit patches/pull request, which is at least something!

Slackware's the same way, most donations come from individuals and very small companies.

Show HN: CoPlay – Enabling In-Room Xbox Gaming for Children's Hospitals
Hey everybody,

My name is Brady. I'm the creator of CoPlay. Think of it as an MDM/fleet management for xbox accounts and devices.

Pediatric hospitals want to allow their patients to play and connect with friends, family and other patients but they have lacked the tools to facilitate and manage this in the past.

A friend and I found this problem while volunteering at our local children's hospital. We are now in 6 pediatric hospitals across the US.

Yup, it's a niche. But it's a cool niche.

I'm sharing this to get feedback, answer questions, contribute to this amazing community and most importantly, HOPEFULLY FIND SOMEONE THAT CAN GET US CONNECTED TO SOME OF THE HIGHER UPS AT MICROSOFT/XBOX. If you have any connections at all please reach out. We believe there is an opportunity for a beautiful partnership there.

Sorry for shouting ;)
>Experience in what? Do you know their roles and responsibilities?

> How do you judge competence of someone whose job and responsibilities are not known?

It's actually very easy to judge, based on the fact that someone who has never done an audit before is now trusted to do one.

I mean, I wouldn't trust Einstein himself at age 24 to audit a small business, no way am I going to think that some rando, maybe brighter than average, will know what they are doing when performing an audit at age 24.

I also think that, if the story is true, the fact that they started at the wrong end of the financials is a dead giveaway that they do not know what they are doing.

IOW, if I saw someone tasked with designing a new car, and they started by opening up MS Paint and drawing tread patterns for the spare wheel, I'd certainly consider them unable to design a new car.

Even if we err on the side of benefit of doubt, even the smartest 24yo in the world is not going to be competent at doing even a basic audit when:

1. This is the first audit that they are doing, and
2. They have never before had any accounting background.

So, yeah, it's quite reasonable to consider them incompetent that the chosen task in the circumstances.
Great site! The only improvement I would ask for is automatically opening the articles with the Wikipedia app, if installed.

LMAO. You clearly need to read more about Hitler's rise to power and how he was actually elected. You people really do not understand politics nor democracy.
How much of that was actually removed in a crash effort, and how much was just fliers saying "please use this other word in the future"?
Absolutely correct.

We’re still not allowed to use “whitelist” and “blacklist” because it’s somehow racism.

We have linters which bar us from checking in code with these words and a bot which scolds us publicly in chats.

Now the same people who applauded that policing of speech suddenly are offended when their explicit political speech is being removed.

It’s just simply hypocrisy.
R has that too.
Is this not practically accessible? https://www.usaspending.gov/
> "We think a very substantial number of people will not show up to work, and therefore our government will get smaller and more efficient"

How is a smaller government "therefore" more efficient? It's only "more efficient" if you can demonstrate that the people leaving were redundant.

ETA:

To my point, if I yank out the GPU from my desktop computer, it's not magically "more efficient" just because it has less hardware in there. You need to demonstrate that I can get comparable results without the GPU for that statement to make any sense. It's possible that it will be more efficient, but it's also possible that forcing all the graphics to be rendered on the CPU in addition to its normal tasks makes stuff less efficient, since the CPU isn't as optimized.

Obviously humans are not computers, it's an analogy and I'm not claiming it's a perfect one, but what bothers me about this entire thing is it's going to selection-bias towards workers who can't get jobs elsewhere. The people who can easily get higher-paying jobs in private industry are likely to take the seven months of free pay and then go get a cushy corporate job that pays better.

As such I think it's going to leave behind the people who can't get easily get another job, meaning that we will have fewer people and these people might not be the most efficient at doing it.

>Ships are also not nearly as prevalent as they were in WW2 (as international capable jet transport didn't really exist then). Vietnam used troop transports, but I don't think Desert Storm used much beyond airplanes.

As someone who supported loading a whole division's worth of vehicles onto ships during the Iraq war, I would like to know what you're basing that on. Sure, the people go by plane, but the people represent an overwhelming minority of the total tonnage moved to deploy a unit.
For people who want to learn programming, I think language models are a very powerful teaching tool. I have learned more programming than ever before because I have been able to ask questions, and get answers directly relevant to what I’m working on. Maybe it depends how you like to learn things, or maybe works better because I already know a base amount of programming knowledge, but I tell people who want to learn programming to ask chat gpt to teach them through a simple project.

The post fell off the front page because it set off the flamewar detector and also was flagged by lots of users. Moderators turned those penalties off after a while.

(What I called imaginary was attributing HN outcomes to Elon, Garry, or Austen Allred (?!))

I'm not sure what heavy-handed moderating you might be referring to but if you want to mention some specific examples, I can try to respond. Mostly what people are complaining about right now is that mods aren't overriding user flags actively enough, so your comment seems a bit counter-trend (which is fine!)
This doesn't appear to be strictly what is happening. Musk posted on Twitter yesterday that he "deleted" the group 18F. That is neither an examination, a report or a recommendation.

I'm sure how the government functions on a technological level qualifies for "things hackers might find interesting," but the comments on these Trump/DOGE-reactionary threads are really disappointing. Too many of them are just signaling the author's ideological affiliations without adding anything substantive/curiosity-inspiring.
I think a lot of people have always thought of it as a tool that can help.

I don't want an LLM to generate "the answer" for me in a lot of places, but I do think it's amazing for helping me gather information (and cite where that information came from) and pointers in directions to look. A search engine that generates a concrete answer via LLM is (mostly) useless to me. One that gives me an answer and then links to the facts it used to generate that answer is _very_ useful.

It's the same way with programming. It's great helping you find what you need. But it needs to be in a way that you can verify it's right; or take it's answer and adjust it to what you actually need (based on the context it provides).
In the US, 70% of the population have iPhones and that number is greater for the younger skewing population.

First you have to go through the trouble of pirating the music from your computer since you can’t easily do it directly from your phone.

Even if you could, you can’t download music on your phone outside of iTunes and put it into your music library [1]. That means you have to add the music to your iTunes library from your computer and then sync it to your phone.

Or you can just pay for a streaming service. But even since 2003 when you could buy music from iTunes, pirating just wasn’t worth the trouble. That was even more so after the iPhone and being able to buy music directly on your phone in 2007.

[1] there is one ugly hack using GarageBand.

It would be interesting to see chemical analysis of those particles.

Pretty nice! Reminds me of StumbleUpon.
Yes: use a different tool, such as Redis.

Updating a SQL database row can be expensive because of the transaction overhead. Once you increment this counter, the row with the counter remains locked until the transaction is committed. But the actual useful work of incrementing a number is already quicker than selecting a random slot. If the increment can be a simple ADD instruction, without transactional semantics, then this random-slot-based approach is slower than just incrementing it. Especially if you don't care about missing a few increments and therefore don't need a mutex.

For even more scale, don't use Redis but have a shared memory block containing your integer.

For even more scale, you can have one such slot per CPU. Make sure they're in different cache lines, to avoid false sharing. Now you have slots again, but they're per-CPU and so you still avoid all the SQL database overhead.

Performance is all about structuring the task as close to the machine as possible.
Isn't that precisely what the article said?

Which would be relevant if the US wasn't dominant before WW2. But it was.

Ironically, the end of WW2 actually hurt US shipbuilding because there was a huge glut of surplus ships on the market and for a brief time a massive drop in trade. British ship builders actually took the title of world's largest shipbuilder back after WW2, producing nearly half of all tonnage in the next decade as Europe rebuilt its merchant fleets.

The countries that had their shipyards destroyed in the war built new shipyards with better technology. They took the lead after that, Japan obviously being the biggest winner in the late 20th century.

Here's three SEC press releases that seem to indicate there's evidence of illegal front running:

Trading ahead of index funds when an index change is announced is front running in my book, but it isn't illegal front running; but I don't consider it less acceptable than buying because the graph makes a funny shape.
> as if amphibious assault against a country that has been preparing invasion for 70 years

You might want to update your understanding of the balance of forces in Asia.

For example: "China’s military has the capability to land ground forces on Taiwan within as little as one week after imposing a naval blockade on the island, according to a Japanese government analysis of Chinese military exercises conducted last year." [1]

Only the United States military could challenge the PRC in the western Pacific. But even that is not a certainty: "Indeed, the overall balance of conventional military power along China’s borders has shifted dramatically in China’s favor." [2]

It's not the 1900s anymore. The PLA isnt a peasant army. It's every bit as modern, and in some cases more so than even the US military.

This oft-repeated analogy to biological systems doesn't make much sense, human individuals biologically stay homeostatic with nature, but human groups have grown exponentially, building civilization as you know it. If we didn't prioritize growth, we'd still be hunter gatherers.
A half assed effort is worse than no effort, because a half assed attempt can easily be weaponized

The issue is a lot of EU legislation becomes powerless, as it's up to individual nations to implement rulings or define exceptions.

And in plenty of cases, these exceptions tend to be broad and equally rife to lobbying like those you'd see in the US.

And there is A LOT of lobbying happening at the nation state level (the level that actually matters) to carve out exceptions.

I already pointed this out with spyware, and there's no reason to presume the exact same thing won't happen with weaponizing AI/ML tooling.
