skysight-inc/HackerNews huggingface dataset:
Pretty interesting effort, but a bit of constructive criticism:

- none of your query results have a date attached! While pretty, an earnings number without a date is like a chart without an axis.

- Just how natural can the queries be? "$AAPL sales estimates" did not return anything. Neither did "$CAT cost of capital". "quarterly $CAT earnings growth" gave me a single EBIDTA number", e.g. not what asked. Is it easier to start with simple dropdowns?

- Why the stocktwits $ prefix? Why cant a company name be used?

- Another "sad face" feature - every not found/no results query takes away a "free query" :(

On more positive note, things look really clean - good job on the design! A great start. Is the long-term idea here to build an accessible place for fundamental data research?

What value added are you providing in your premium product (aside from heatmap) over just going over to EDGAR archive?

Exactly - I look for articles with a high number of comments, and usually jump into the comments first.
I think the Y-meters are distracting. I like to judge articles on their title.

I can see the different values on the Y-meter get a nickname btw, dash, L, C, O...
Why are you resistant to doing the market valuation?
It is cheap and beneficial. No matter hire certain you are it will validate and refine your offering. You get to learn the market size, the price point and create reasonable estimates for adoption all while collecting free feedback on features.

No matter how certain you are talk with your customers!
Thank you for showing us. I have two pieces of feedback.

1) The score isn't most important. The headline is. This is why the headline is in black, and the score is in gray. We don't come here to compare news importance, the site already does this for us by sorting. We come to read news. And having a small pale gray score replaced by a big attention-drawing glowing orange square goes against where the focus should be.

2) I do part time design and understand the temptation to style your presentation so it enhances your concept, like add perspective, drop shadows, and so on. My team does this when presenting business card designs to clients, because the actual graphic looks so simple and boring on a monitor, the client won't "get it", if we'd show it as is.

But a website isn't a 3D slab floating in space, so in this case the styling is a distraction from your presentation, not an enhancement. Keep it simple, when simple works.
The Y-meter thingy seems much less intuitive in order to keep track of the points compared to a count.

That's a good question. UTC is almost certainly still the best candidate even in that case because:

* it's not affected by daylight savings time, which in many candidate timezones causes at least two complex and error fraught time discontinuities every year, and which requires manual intervention at the whims of the US Congress in the USA.

* UTC is the lingua franca of machine time communication -- if you ever have to, e.g., send data about transaction times, server event logs, order histories, etc., to any third party or API, then because there are 23 other timezones besides yours, and data normalization is important, they will almost certainly expect ISO8601 UTC. Yes, ISO8601 has time offsets. No, not all libraries implement them properly on either side.

* The first time you ever have logs from two different timezones -- e.g., a service provider log denominated in UTC and yours in PST -- you will hate computers so much that you will likely quit your job, throw your keys on the floor, and go run a hotdog stand down by the pier rather than deal with it. This is an honest response to time and localization issues but think of your children.

Dunno about the y-meter... Would rather see a number than something visually unintuitive (for me). Also from afar it looks like a bunch of checkboxes.

Also from an eye tracking/heat map standpoint the number of comments being entirely on the right is really tiring... I want to easily just sweep my eyes down on the left to click on articles and the voting score + number of comments are good indicators.

I like the color/font changes that make the site pop a bit more but that's a minor thing. I also appreciate these design docs for their discussion of visual value but these changes also reflect a certain lack of awareness from a usability standpoint -- it just doesn't add much in value, but rather detracts from it by pushing in new design. I'm thinking more Digg 4.0 than FB revamp here.
Speculating (never actually been involved in hedge fund or super advanced math): what are some potential ideas that RenTec could be working on? Please state your speculation in terms of the mathematical / investment problem to be solved.

Is this inviting remote code execution exploits on your websites? One of the reasons most people don't write C/C++ for websites is safety. It's a lot harder to introduce entire categories of bugs when you use safer languages.

Looks great! But I am actually not sure whether I like the redesign, or the way you presented your redesign.

GrexIt was built to help teams collaborate around email threads for customer support. Overall, we make it very easy to assign/track an email thread and move it through a very light workflow. Our focus would be on building on this, and bringing in more functionality for the customer support use-case.

You guys are doing some awesome stuff on Streak!
I agree. Actually, showing the number inside of the meter would be nice. I also agree with another commentor, oftentimes im after the comments link, dont stick it on the other side of the page. Id really like the ability to click one link that opens the source and the comments at the same time (RES adds this functionality to reddit for instance)

The Y-meter isn't very useful to me.

Respectfully, I don't care about an abstract graph, nor about having to remember point ranges for its various states. I care about the actual points, and seeing their numerical value is faster and easier to comprehend.
Maybe this could start as a chrome extension?
Would anyone speculate about what mathematics and methods they use to achieve a 50%/yr return? I wonder if there's a way to reverse engineer their model by e.g. looking up which research papers their employees published prior to joining RenTech.
Right or wrong I use the comment count as a proxy of how interesting the link is - moving it way over to the left breaks that.

Hey Jay,

This is really cool. One idea is it would be great if you could interface with EDGAR and gather the links to the various financial statements. The EDGAR database search/navigation is horrendous.

As another commenter said, it would be great if it could detect the company name or at least the ticker without the $.

Also, a failed query subtracts from the guest query allotment. That doesn't seem ideal as I'm first learning how to phrase my requests.

Lastly, mutual fund data would be awesome. Morning star rating, fund performance, fund assets, etc.

This game is like what the Sims should have been all along. If you think building a dream home, getting slapped by a neighbor for an ill-timed kiss, and drowning your characters in their own swimming pool were interesting, imagine how you would feel if you could make your house a 100-story skyscraper built from obsidian and glass, with subbasements that pierce three separate underworlds before breaching Hell, witness a tantrum that ends in broken bones, severed limbs, and execution by hammering, and kill your characters by sending them on a rollercoaster ride that ends with their minecart smashing into a mountainside and falling into a volcano.

All of EA can produce a game where the tiny people pee their pants instead of using their own toilet. Two guys at Bay12 can produce a game where tiny people can have both arms snipped off by a monster with crab claws and still kill it by choking it out with their legs and then biting its head off.

The Sims let you train your stats with mirrors and home gyms and bookshelves. DF lets you train stats by stabbing people with lever-operated spear traps, dropping live puppies onto their heads, forcing them to drown for short intervals, and making them wrestle with naked goblins.

And all it costs is a voluntary donation to support a grand total of two people.

Very surprising you couldn't take the time to ensure that markers are not directly obscuring other markers. Right now in my browser the US has exactly two items shown as do many others due to this obvious flaw.

So in summary it seems many are saying the data is flawed and the presentation is clearly flawed.

Perhaps it was a little premature to expose this to the world?
From a visual perspective, I like it.

For what it's designed to communicate, I like the Y-Meter. However, I question whether what it's trying to communicate is in line with the HN ranking system.

The ranking system combines several signals to give the front-page order and is designed to give new, possibly interesting but currently low point links more prominence by being higher up the ranking. This gives them visibility so people can then vote on whether they're interesting, and hence should be kept at a higher rank for longer.

Without promoting new low point content, it's difficult for anything to rise to the top.

By making the current ranking more prominent, the Y-Meter would have the effect of reducing views for newer low point content.

PE, big banks, all of that money is based on information gathered from the companies before the rest of us peons get wind of any of it. John Q. Public is playing what he thinks is a fair lottery, while the wizards are pulling the levers behind the curtains. If we as engineers could figure out a legal way to "earn commissions" (read: steal from tens of thousands of people every year based on information asymmetry), then $500k is no problem. Until then, however, we are confined to, you know, actually trying to create value for people rather than extract it from the system.

Pardon the cynicism, I am pretty unnerved by our whole economic incentive structure.
There are source links on the page. At the bottom.
The way you described it sounds possible, yes
I like it, here some few points though.

- Time ago is important when you are checking out the "new" items on HN

- Domain from where the article came from, seems to be more important then the user

- The HN Meter is nice, but it's more dificult then the point system for new users.

- The ammount of points are too far on the right, to see this, people have to see the right corner and there will be difficulty to see which comment_count belongs to which post.

Although i really like the redesign, it's a hard thing to do for something like HN.. Where it's beauty lays in its simplicity...

Good job though!
Depends on the threat. If you host your own email, there is a whole class of legal intrusion (persuasive cops, warrants, national security letters) that you get to hear about if they want your archives or stuff that's encrypted on the wire. The same applies to corrupting employees; I'm going to know if somebody bribes my sysadmin for access, because that's me.

There's also some benefit in avoiding being part of a monoculture. Big mail providers are an enormously interesting target for both spies and criminals. Breaking into random quirky personal servers, though, has a very different cost/benefit ratio.
Few comments, take these with a grain of salt.

- This should be coded and turned into a working prototype! I imagine an HN reader with some spare time on their hands might attempt this.

- The square "y-meter" idea is neat, but it's difficult to parse at a quick glance. A circle might be a better alternative, where the size and intensity of the circle indicate the strength of the story.

- The order of each story element in your comp goes like this: Title, username, URL, and finally comments. I think the URL is a lot more important than the user who submitted it.

- The orange •'s in the string are distracting. A significant space, something like three or four &nbsp;'s might be a better way to separate those components.

- Having an arrow in addition to the y-meter is kinda noisy. Those could be combined. Sorta like Svbtle's hold-your-mouse-here-to-vote ... if the y-meter was replaced with a circle, it could expand or :hover into an arrow to vote. Not suggesting hovering will cause a vote, but rather a hover will indicate that you can vote.

- Having the comments encapsulated in the little comment bubble is fun, but at first glance the type looks way too tiny and having it orange is tough on the eyes. It's doing more harm than good.

- The stories could use a bit more vertical padding between them.

Finally, don't take these comments the wrong way. I think 90% of the time something feels great inside of Photoshop, especially after mucking around with it for hours or days, but the only way to prove that the UI is great is to actually build it and play around with it.

I hate to say it, but people keep "redesigning" HN without actually solving any significant problems. The only problem this site has right now is that it's unfriendly on mobile devices. Every other attempt has just been putting lipstick on a pig. That being said, it's a fun exercise and thanks for sharing your version. You put a lot of great thought into this and it's fun to read these.
Its a good question - what are the habits of a HN reader?
and 30 years of any radiation pressure.
And the fact that it requires a legend… probably adding the values directly into the meter could do the job.

> no need to spin up a linux container for simple development

But why not do this, anyway?

These containers are very cheap and come with very little overhead, they are truly isolated and they are easily shareable. I'd say there is no need not to spin up a container for everything, it's not like you're going to run out of RAM...
I find the Y-meter a bit gratuitous and not very readable. For a better solution that works right now, check out HN Colors: https://chrome.google.com/webstore/detail/hacker-news-colors....

I also agree with gamerDude that deemphasizing the comments by putting them on the right is not a good idea.

It's funny, despite all its flaws, I don't think I've seen an HN redesign that I like better than HN.
That's "easy to share" which is a much greater hurdle than "publicly accessible". I want strangers to be able to use my wifi in the middle of the night from outside my home. I want devices to connect without any questions or hassle.

Not feeling the square meter to indicate interest at all. Actually, that's the only thing I don't like about it. I'd rather see things with more gravitas given larger sizing, similar to how twitter's treating retweeted and favorited tweets on their new profile pages.

Otherwise, i think it's excellent.

The article distorts the history of RenTech. I believe Simons started doing non-quant trading and he acquired RenTech, which was started by Berlekamp.

Given the nastiness of this attack (a fully interactive client-side backdoor!), the non-trivial nature of the algorithms and coding theory required, and the slow uptake of Flash patches especially in enterprise [1], this seems like downright irresponsible disclosure to share such a detailed post (with a repository and detailed instructions for script kiddies!) so quickly after notifying companies. I can understand all too well how excited the researcher must have been to discover this and share it with the world, but jeez: wait until the Flash patch hits an inflection point on the adoption curve at least!

I feel the Y meter is too complected to the eye; especially if you are doing a quick scan to see the top voted posts that you've missed. Even with a number you can make a rough guess without actually reading the number by the length (number of digits). I think a subtle horizontal bar, or a boxes with varying color intensity would do a much better job.
