Project: I am working on improving the 2 factor authentication (2FA) user experience for end users. Problem: 2FA is an east way to drastically improve one's security posture with many sites (e.g. AWS, Github, Google, Stripe, etc), but it is still an incredibly annoying user experience that gets worse the more sites you use it with. - When I pick up my phone to enter a 2FA code, I often get distracted by an email, tex…

Just curious, how are you planning on approaching this problem in a way that apps like Authy aren't doing?

It sounds like he's going to support OTP 2FA, likely through a browser extension? That's my guess anyway.

I'm designing a 3D printed robot arm that doesn't suck. It uses all brushless outrunner motors for at least the 4 large axes (final two in wrist may be hobby servos for now). The arm is similar dimensions to a human arm. Initial calculations show it will be able to lift more than 2kg at full extension if I can make it strong enough. Actually the (rough) calculations say more than 10kg but that would break something.…

Cool. The onshape link asks me to login right away. Without logging in, I don't see your 3D item. You're invited to also upload the robot arm to www.3dprintmakers.com.

Onshape is free and cloud based. It's good because you can easily create an account and edit the file yourself, but a bummer because it's not free software and you can't export raw files, only dumb solids.

Despite the drawbacks, I'm keeping it in OnShape though, where anyone can fork and edit the file for free.

Problem: Writing regular content for your product's blog is time consuming. Project: We are working on automating the content writing process. Articly ( https://articly.me ) is a automated content strategy and writing platform. You give us your site or product and every week our platform sends you a new article to post to your blog.

I'd like to "TRY" before making a bigger cash commitment. I can pay BUT want to have an 1 off article to see the quality. I am not saying free. Just gimme a taste. Before i fork over the dough.

I'm an undergraduate at UMD working remotely. As a side project, I am working with a friend on https://txtpen.com txtpen provides highlights and context comments for websites. It is like medium for non-medium sites. Most importantly it follows the W3C Annotation Standard. It is so close to finish. If you have a tech blog and would like to be test it please email me at ricky@txtpen.com Any feedback is welcome. Thanks…

How's your side project differ from https://hypothes.is , and how come it's not possible to highlight parts of another highlighted piece of text? Good job for following the W3C Annotation standard!

Thanks for checking it out. txtpen differs from hypothesis in 2 aspects.

1. Full publisher control. Publishers can moderate and pin highlights on their sites. However, all annotations can be retrieved via RESTful API as per W3C standards.

2. Only pick the best highlights to value add the reader. Otherwise annotation is nothing more than digital graffiti.

Also, we strive to be the best annotation service out there. The load speed is within 150ms compared to 2080ms of hypothesis. And we plan to cut that by half to within 60ms which is below perception threshold. The experience will be magical.

http://bsnip.com - A screenshot and annotation utility. I wasn't happy with any of the available options, either the price was too high, or the feature set was lacking so I decided to make my own. I believe BetterSnipper stands out in its ability to dock to the side of the screen, making it especially good at taking/editing/uploading multiple screenshots. I've been working on this side project for a few years now and…

...and my download link was broken this morning. Just fixed this in case anyone wanted to give it test drive now.

As johnmaguire2013 guessed, we will have a browser extension which will request a 2FA code from the mobile app. The mobile app will receive a push notification and ask the user whether they would like to allow or deny the request for a second factor of authentication. The user only needs to click one button on their phone and the 2FA code is securely sent to the browser where everything else related to submitted the 2FA code can be automated.

The browser extension can integrate with any site that currently supports 2FA without any integration or changes required on the part of the sites.

Let me know if you have any more questions! Do you think you be willing to change your 2FA workflow to the one described above? If no, what are some of your concerns, thoughts, etc? Any and all feedback is appreciated!

Yup, you nailed it. That is exactly the plan. Any thoughts on that approach? Do you think you might be willing to update your current 2FA workflow to the one described above?

http://www.eathow.com/ EatHow is a web app that helps you plan your meals and gives you recipes you can make with the food you already have. Long term Id like to completely automate grocery shopping and meal planning so all you have to do is a one-time setup where you set a budget and diet preferences and Eathow takes care of planning everything else. While anyone who cooks at home would find it useful, it would be p…

My wife and I have talked about the need for a recipe search based on the food we already have for a long time, so I like this idea! Where do the recipes come from? I mean, do you add your own recipes?

I've been making all the recipes and adding them. Initially, I was using recipes from a multitude of sites but that turned out to be pretty terrible for user experience.

There are 80 now and I'm adding more every week.

(1) Considering the problem of real time logistics for spoilable goods to support our startup http://8-food.com/. Interestingly in nominal approach I am finding a lot of crossover with a previous cryptocurrency-focused transaction system I conceived building a Bitcoin exchange 6 years ago @ http://www.ifex-project.org/our-proposals/ifex/2012-04-11-pa... ... basically each node within the network becomes an independent agent with centralized reporting but also an internal logistics and scheduling system. Many potentially useful related fields exist like Supply Chain Management (SCM), Operations Research (OR), Just-in-Time (JIT) manufacturing, high availability engineering, risk management, game theory, etc.

(2) Learning mechanical engineering to build the http://8-food.com machines. Many different sides from HVAC to industrial magnetism to UVGI to exotic door hinges to available materials and production processes to 3D modeling. Big job. Visiting factories, speed-reading huge numbers of books.

(3) Relocating my family and company to Shenzhen. Getting buy-in, travel and shipping, getting to know the city, projecting near and medium term requirements, real estate hunting, etc.

(4) Determining and achieving the ultimate international legal structure for the company. Obtaining advice, comparing different jurisdictions based upon their legal and financial infrastructure, degree of precedent, multi-provider fees, government fees, possible bottom-line benefit under disparate investment scenarios, etc.

will it be fully 3d printed (no metal/carbon tubes)? I think the main problem with hobby robot arms is flex in the arm itself and backlash in the motors. Low cost arms (eg. dobot) have "0.1mm repeatability" with no load but the moment you put a kg on the end effector it starts flexing.

Aside from bearings, motors, and possibly some fasteners, it will basically be entirely 3D printed.

I'm using printed spur geartrains that will have all kinds of backlash. In an effort to make something that is primarily printed, I'm throwing any hope of precision out the window. At least mechanical precision - we can use visual servoing to get more accuracy at the end effector.

But my hope is that the other benefits (low cost, easily changeable design, good speed and strength characteristics) will make it useful even with poor rigidity.

I imagine for example pulling things out of fixtures and moving them in to boxes.

There must be a good variety of tasks that can be done with an arm like this. I'm working to the strengths of 3D printing and not trying to fight what it isn't good for.

That said, I may reinforce the frame with a carbon fiber wrap if more stiffness is needed.

The goal is to have a low BOM cost AND low tooling cost so I want to avoid the need for any metalworking equipment.
