Show HN: A Platform to Explore Hackathons Around the World
I built a website which lists all hackathon posting from various other sources (currently Devpost and Unstop), on click it redirects to the original source.

Surprisingly, the APIs these websites used were open, which they used to populate their page with hackathons data.

So by spending maybe around 3 hours? This is the end result. It is built using Nextjs 15.

I tried to make it as best as I can, but hey, would love to hear any comments on improvements. There maybe some mistakes but yeah, I am here to learn.

Also, not the greatest of the UIs, but I wanted to get out the MVP, while most of my time was spent in normalizing the JSON from different hackathon website APIs.

I am looking to add more sources, eg. devpost, hackerearth, hack2skill, etc. I might need to scrape their data as their HTML is prepopulated when it is fetched, or have to find some other turnarounds.
There is a difference between correctly stating that 2 + 2 = 4 within a set of logical rules and proving that 2 + 2 = 4 must be true given the rules.
C was designed in the 1970s with the goal of giving you minimal overhead, bar using a macro-assembler.
The way C handles "strings" provides exactly that.

The OP clearly stated that he did not mind the overhead (in terms of executable size, memory consumption, execution speed) in his particular use case.
Sorry I wore you out, glad you were able to find the strength the post three comments afterwards.
Python doesn’t follow semver [0], it follows a general major.minor.bugfix, but with an extremely liberal definition of minor (“less earth-shattering,” as they describe it).

PEP387 requires that introduced incompatibilities have a “large benefit to breakage ratio,” and that any deprecations last a minimum of two years.

FWIW, Kubernetes has a similar approach. Breaking changes occur all the time with “minor” version updates.

Show HN: Callosum – A smarter OpenAPI editor/client
A couple years ago I was really frustrated by Postman, it couldn't do basic JSON schema validation, and didn't interoperate well with the OpenAPI spec I had to use for serverless deployments. On top of that, they started requiring an account and cloud sync, and other things I just wasn't comfortable with.

So what's an engineer to do? Build yet another API Client of course! [0]
It's still fairly rough and crashes more often than I like, but it's basically at the point that I've switched most of my usage so I figured I would rip off the bandaid and do a Show HN.

Short list of some of the (IMHO) cool features that you can't do in Postman:

* Generate JSON Schema from request/response data.

* Generate request content template from JSON Schema.

* Reusable Schema components (Analyze->Extract Schemas menu)

* Basic field and JSON validation (so much more to do here!)

* Embeddable environment and encrypted variables [1] in the OpenAPI document.

* From scratch, run a MITM proxy and record API requests, then automatically generate an OpenAPI spec.

* Deep linking w/o a web server.

There's a short youtube playlist of some of these features, but I need to spend some time demoing the rest of them. What is most interesting to folks?

I would love to integrate better with the API doc generation tools but need to figure out how that would look. Speakeasy/Redocly/etc are some great projects and I don't want to reinvent the wheels there.

I would also seriously appreciate some tough love/feedback to make this even better. I'm sure someone smarter than me can pick apart the variable encryption (I broke rule #1 of cryptography and rolled my own, but I couldn't find a similar use case)

Haha I was checking the comments precisely to see if this was the case. This happens nearly everywhere a language that isn't Java, Python, Ruby, Go, PHP, or JavaScript is used. IMO it has more to do with tech labor arbitrage[1] than anything technical. Even if a system is punching above its weight, over time, the Weird Language Choice spooks people enough that they get the rewrite bug.

Bleacher Report is a funny example: it used to be a darling example of Elixir, where a migration from Ruby -> Elixir claimed a move from "150 Ruby servers to 5 (probably overprovisioned) Elixir servers."[2] But then management and politics got scared, moved it all to more conventional tech, and the whole system suffered (see this legendary post[3]).

Fred Hebert describes a similar thing happening with a migration from Erlang deployments to Go/Docker/immutable, where you lose some pretty valuable capabilities by migrating to more conventional tech.[4]

I don't see this changing anytime soon -- we came of age when it was viable to attract investment with the promise of tech innovation. These days, those are liabilities because managers misunderstood the "Use Boring Technology" post the way consultants bartardized "Agile" (taking decent advice and misunderstanding it into something wholly different and horrifying). The result is you've got companies with customers in the 1000s using k8s, calling it "simple" and "Boring," whereas that same company would be called amateur if they did things like stateful deploys on-prem.[5]

At least we'll always have WhatsApp.

I've never drunk and find pubs awkward and generally un-fun. Some of that is I maybe want one small soft drink a day at most anyway, and I'm quickly just standing/sitting without a drink, worrying I've got nothing to say, and seeing no good reason to be there. 100% on me, and I only mention it as context to the below:

I've seen a lot of people drinking the modern zero/low alcohol beers (lucky saint maybe?) and it largely just works. They're happy, and get to engage feeling pretty much like normal. Obviously if the goal is to get drunk quickly then it sucks, but observationally you've got a fair few rounds before it appears to be a barrier.

> Those YouTubers might not be producing erudition, but as long as they have watched a ton of content and decided what the good stuff is, and as long as their tastes seem to align to mine, then their opinion is still very useful.

In most of the (big) YouTuber movies and TV shows critics, I have a very hard time knowing what is their taste and what is a piece of art.

I think in the future the role of a critic will be more to the technical aspect of the piece, and how it fits in their lore than something related to the taste specifically.

In my case, I cannot watch most of the modern TV shows 'cause most of them lack good cinematography, character development, and sound which are important aspects for me in terms of immersion and engagement. Most of the shows today with CGI, only closed camera takes, and lack of external shooting look like sitcoms of the 90s.

That's I think most of the Youtube Critics channels lack, that kind of nuance around those technical aspects.

The engineering requirements to build a branch of a company with the security needs of specialized SOC would be crazy endeavor and to the point that whatever comes of it would probably look as foreign to the main company's function than what currently exists. Having a separate non-profit agency handle these cases would not only allow for the agency's incentives to align, but also the overall security design approach to its facilities and internal networks. It's a win-win for both private and public interest imo.

> Gold will always retain value.

After >40 years, gold has only just gotten back to its 1980s inflation-adjusted price:

* https://www.macrotrends.net/1333/historical-gold-prices-100-...

Papers have been written on how it does not hedge inflation:

* https://www.nber.org/papers/w18706

* https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3667789

See also Roy Jastram's The Golden Constant: The English and American Experience 1560 to 1976:

> Andre Sharon, head of the international research department at Drexel Burnham, Inc., notes, “the value of gold essentially derives from its capacity to preserve real capital and purchasing power.”† I select this particular quotation because of the prestige of the organization and the position of the spokesman, but statements in this vein can be found in great numbers. They can be traced back for generations and in many countries. How can this proposition so contrary to statistical fact become so widely believed and quoted? Possibly because gold has preserved capital in cataclysmic cases it is easy to infer that it can be trusted to do the same in less severe circumstances. To extrapolate from gold’s protection in singular catastrophes to its use as a strategy against cyclical infation is an example of faulty inductive reasoning.

* http://csinvesting.org/wp-content/uploads/2016/02/RoyJastram...

So if the barbarians are (close to literally) coming across the fields, gold can be useful to hide or take with you as you head for the hills, but for most economic situations it is not useful.

One common link between Palantir and Andruil is that they are both in the Peter Thiel constellation. One founder, Stephens, was very involved in the Defence transition team for Trump's first term.

> And you believe that in an economic crisis, people are going to want to buy these things?

Gold is obviously more common in some cultures, and could be used for trade if paper money swings wildly. For example, a kilo of gold (32.15 troy ounces/$86k) is not an uncommon incentive gift from real estate developers in China when purchasing properties, to offset variations in costs and pricing. However, in the US, my observations have been the gold buyers are looking for an easy buck.

China is very different. People in China are buying "beans" of gold for $87. Chinese consumers have fewer investment options that are secure, and real estate investments are less favorable now.

"...there is a growing sentiment that the gold market is governed no longer by economic factors but by the whims of Chinese buyers and investors. “China is unquestionably driving the price of gold,” said Ross Norman, chief executive of MetalsDaily.com, a precious-metals information platform based in London. “The flow of gold to China has gone from solid to an absolute torrent.”"

Another interesting quote:

"When China increased its gold holdings in the past, it bought domestically using renminbi, said Guan Tao, global chief economist at BOC International in Beijing. But this time, he said, the bank is using foreign currencies to buy gold — effectively reducing its exposure to the U.S. dollar and other currencies."

China is one of the largest foreign holders of US treasuries. It may be trying to gradually dump them while preserving the value of the bonds.

2 is definitely true. 3 is much more interesting and likely true but even saying it takes us into deep philosophical waters.

If every true theorem had a proof in a computationally bounded length the halting problem would be solvable. So the AI can't find some of those proofs.

The reason I say 3 is deep is that ultimately our foundational reasons to assume ZFC+the bits we need for logic come from philosohical groundings and not everyone accepts the same ones. Ultrafinitists and large cardinal theorists are both kinds of people I've met.
