It's not monetizable, but I'm playing with reinforcement learning. It's incredible to watch a computer "learn" to play super mario using just input pictures.
Neural nets in general are much less complicated than I thought they would be, at least as a practitioner.

Almost all news and social media site structure is derived from research using the Skinner box[1, scroll down to A Man, a Plan, and a Rat in a Box]. Researching operant conditioning, they found that introducing randomness to some sort of dopamine release would cause habitual behavior of the action that caused dopamine release. This reaction to novelty was then successfully transferred to humans. This is most obvious on Reddit IMO, with "gems" interspersed between vapid, uninteresting posts.
I'm actually making an alternative to Facebook that shows posts chronologically in the feed instead of using machine learning algorithms to make them addictive. I also plan to not include a share button on posts. I think these two changes would make it far less addictive and better for users.

Is there any way I could get one too? Email [email protected]

Not to be too spammy, but discovery of such sites is why I'm making Feldot, a social domain aggregation site. There are so many sites available out there like this to browse, but we never see them when using existing search engines.

I'm Luke Hackworth, developer of this site. It's really difficult to find new websites nowadays. The big players penalize posts that lower engagement outside of their own sites, meaning most people are only exposed to a tiny portion of the real web.
I created Feldot to enable the exact opposite behavior, pushing the user to explore new domains. Instead of a link aggregator like HN or Reddit, it's a domain aggregator, pointing to an entire website.
Because it's tough to find new sites, I also created a tool to help find new sites, Feldot Explore[1]. It's not just a list of domain names; each one was scanned to verify that a web server is running on it, and some basic scans were done to remove a majority(but not all) parked domains. The list was checked a year ago so it's not exactly fresh, but I think the signal-to-noise ratio is still good enough.
I posted this a year ago and it gained no traction, which isn't surprising considering its appearance. I revamped its UI, though it's still very much a work in progress. Any feedback, positive or negative, is very appreciated!

> Why do you need Active Directory or LDAP?
Primarily authentication, authorization, and accounting[0]. Setting up a new user account on every single computer that an employee may at some point sit at gets very expensive. Many businesses (if not immediately then eventually) have security concerns that require Administrators have the ability to immediately lock users out of the system or be able to audit recent activity. AD/LDAP facilitates this. It can also automate standard settings like network drives, screen lockout settings, homepages, and all sorts of other settings.
> You either figure out how to use the computer they give you, or you don't
Standardization of processes and training can reduce training time considerably. For industries with high turnover, this can make a difference. You've gotta remember, not everyone is a knowledge worker. Tons of people are more like cogs in the machine of the company, which isn't necessarily a bad thing.

I'm a systems administrator for a small MSP. I've used Linux as my primary OS for 9 years, despise using Windows, and I can tell you with 100% confidence that nothing but Windows is ready for prime time, and for one major reason: _ease of administration_.
Think of the growth cycle of the vast majority of businesses. Almost all businesses are started and run by non-IT people. They buy Windows machines because they're simple(don't have to worry about OS installation, chosing a distro, etc), have Microsoft Office, and work with any and all enterprise software they use. This gives them a key advantage for small businesses. Like it or not, Linux is just relatively hard.
Where Windows _really_ shines, though, is when a small business transitions to being a big-small or medium-sized business. If you have a couple dozen computers and a couple dozen users to manage, do you think it would be worth it to have a linux admin spin up an LDAP server with kerberos and all the bells and whistles needed, then be hired to manage that infrastructure? No, they're going to contract someone to spin up a windows server to manage user logins, create a network share, and call it a day. The infrastructure is super-stable, and when the cost of labor is considered, it is considerably cheaper than letting the system be the plaything of a local Linux zealot.
It's only when you consider big and massive businesses that Linux can really be viable, and even then it ain't cheap. Most big businesses grew in a Windows environment, and switching the core of your IT infrastructure sure as hell better be worth it to warrant the massive labor costs, IT fire fighting, and drop in employee productivity that will result.
No, Linux infrastructure and desktops really only make sense for companies that are either highly technical, need absolute control of their hardware, are _extremely_ price sensitive, are (or hope to become) massive, or a combination of these.

Yeah, a single iso can be recovered from multiple disks with different damaged sections using software like ddrescue[1].

I would agree with this if not for my recent experience with duckduckgo. While Google's search result quality has sharply deteriorated in recent months, duckduckgo's results have stayed flat for the most part, to the point where ddg's result quality is more often superior to Google. If it were a matter of SEO manipulation, wouldn't ddg's quality decline too?

Spam: unsolicited usually commercial messages (such as e-mails, text messages, or Internet postings) sent to a large number of recipients or posted in a large number of places[1]. By that definition, it is spam.
> user testing has been done
User testing isn't flawless, and is what got us the ribbon in Microsoft Office for example, an incredibly unintuitive interface.

Defaults matter. And currently, Firefox fills their new tab page with spam and self-promotion by default.
I have an idea to have variable Q training propagation based on the amplitude of the reward so that bigger rewards propagate more, but I haven't got there yet.
Here is a great video on reinforcement learning[2].
