Just to be clear: it's not for every student (at least not yet!). We are in a research phase sharing it with a limited subset of users. More details about our approach to the responsible development of AI: https://blog.khanacademy.org/aiguidelines/
It better not be for every student. I am very familiar with Khan Academy as I am currently guiding a student through several AP courses on khanacademy. In my opinion, khan academy's time would be better spent fixing the UI for teachers, and improving the organization of the physics curriculum.
I would prefer that khan academy not be dragged into some PR fluff piece for some AI shill.
This argument has a pretty standard counterargument: organizations can and should do more than 1 thing at a time. It's a non-profit so you're probably better off contributing your ideas to them.
Do you know if/how someone can get involved with this at the research phase? I have a daughter who will be entering 1st grade next year and I'd be interested in having her try this out if there was a way of signing up.
I feel young again!! Logged into my account and an attempt to join the waitlist returns this:
"If you want to test Khanmigo, your parent or guardian needs to sign up.
At this time, only people ages 18 and older are eligible to sign up. Please ask your parent or guardian sign up and add you to their account."
I was a high school English teacher for about ten years before transitioning into tech last July. Has KA explored assistive assessment tools for in-person instruction?
I frequently find myself in the middle of many things, one of them is that although I oppose the grotesque plunder of the public and citizens of countries by neo-aristocrats claiming to do one thing or another amidst blatant lies of social welfare, I also object to slavery and therefore cannot condone that everything should be free since people like being compensated for their work, and not by being indentured and forced to do things.
Things have to cost, even if they wouldn’t have to cost as much if we could stop the psychopaths at the top constantly plundering and raiding the resources of the productive people to maintain their parasitic and decadent lives.
We think that the web should be fast, beautiful and accessible on every screen. Today that means making the web better on desktops, phones and tablets. Tomorrow it will mean Google Glass, smart TVs, and a host of other web-enabled devices.
We have tons of positions open - some of the most pressing are Front-end Engineer/Designer, HR Manager, Talent Acquisition Manager, and Product Manager. Some of the products we work on:
- Performance analysis tools written in Python and Postgresql, collecting data for billions of users and aggregating that data to improve the performance of responsive sites.
- Performance improvement tools, written in JavaScript on the client-side, and powered by many different backend services (image resizing, JS minification, etc) powered by Python and Node.js.
- Cloud based application that allows you to manage your projects and create amazing mobile/tablet experiences, and that provide an entry point into our performance tools. Written in Django and Backbone.
The point is, if his goal is to truly make him understand, he can achieve that goal MUCH faster if he doesn't hurt the ego of the person he is having an argument with. When your intelligence is insulted, you will spend a lot more time defending yourself rather then accepting a point.
This is true on a micro, per-interaction scale. On a macro scale, it can be more beneficial in the long run for people's egos to be hurt when they're wrong. For someone like Torvalds, the macro scale of interaction matters a lot.
You're basically supporting the "everyone's a winner" mindset. Sure, on a micro scale, tell the kid they were a winner for participating, guide them, and for that particular interaction everyone comes out ahead. On the macro scale, it's better to feel the sting of being wrong so you can learn from it.
Completely agreed. When you insult someone personally, they will defend themselves much sooner then they will accept your point. Instead of arguing against his point, he insulted the petition makers intelligence. When trying to make a point to someone, it's always better to do it without hurting their ego. Always.
I wouldn't imagine having two or more images would make much of a difference until you start reaching the max # of TCP connections per host, since these images would download in parallel. Would still be interesting to see results for.
Article author here -- I agree, it would be interesting to see results. One reason for using more than a single image: no navigation timing API in iOS.
iOS may now lag behind Android in handsets shipped -- but it's still a dominant player in web visits on mobile!
Unfortunately that means that for RUM tests I needed to have results that were insensitive to differences of a few ms.
Here's a petition asking Apple to include the navigation timing API in a future iOS release:
As someone who is grateful for your research and analysis, thank you, but filing a bug report is going to be WAY more effective, at least for iOS. https://bugreport.apple.com/ will get the ball rolling, even if it's been filed already. The more reports they get, the more likely they'll look at fixing the issue, especially if good use cases are provided.
I was recently looking into some prebuilt libs for emoji support on web. One of them had a sprite, the other used data URI's in all of the background-image:url() parts of their core CSS. The sprite was crunched down to about 500k after some optimization tweaks (pngout, etc.) the data uri version could not be optimized, it's CSS file weight in at over 5MB.
The decision was pretty easy to make after that discovery.
Amazing story - I applaud the intestinal fortitude. I have long though about doing this myself. I have travelled quite a bit more then any other 24 year old that I know, and while I love travelling, I also love too many things about home to become a permanent traveller. I love the adventure of travelling and meeting new people, there is also tons of value in long term relationships with family and friends, and those are things I could never give up. Satisfying the travel bug while still maintaining strong long term personal relationships is hard!
I was thinking the exact opposite. I have been thinking about switching to Android for some time now. I think it is safe to say that I'll be switching to Android for sure now. I was not impressed with a lot of the changes to iOS 7 and think a lot of them are down right ugly (icons, blurred background everywhere).
You're gonna switch just because they changed the UI? Aren't all of those new features available on Android? Plus, Google must be cooking some good stuff for next Android, so you should hold your horses :)
The UI I could take or leave. Apps finally being able to process in the background- that's something else. But by and large, it feels like they're catching up to Android, but not surpassing them.
Not really, I promised myself I won't go back to using iOS as a phone OS. For the next iPad Mini it'll be great but I'll just wait for Paranoid Android to innovate and get the HTC One Mini's successor. I admit though, that Android is going to be behind doing a full revamp like this.
