Very exciting! sounds like we're finally leaving x86 behind
Important question for me as well. As a solo amateur developer I don't have time to keep up with the constant development of all the different platforms.

I love the idea of this tool.

This came just at the right time. I'm putting together a series of animations for patient education. In trying to make things cross-platform I had to resort to AE and non-interactive video. Lottie looks like it will enable me to string together something nicer, using native drawing functionality, and can incorporate more interactivity.

Would love to learn more about this single billion dollar mistake
Are there comparable speech-to-text or conversational agent APIs in the Azure or Google Cloud ecosystems?
Re:Gun – “Self-hosted Firebase” on Sunday August 30, 2015 @08:03PM (#10144854)
I believe deepstream which received good feedback on HN also solves a similar problem.

With such proliferation of self hosted FireBase, can anyone in the know share their experiences with these solutions?

Re:Firebase is Joining Google on Friday October 24, 2014 @07:23AM (#8503107)
Looks fascinating. Setup of the open source version seems quite involved, are there containers I can use to try it out?

For my applications in healthcare I'm often forced to use in-house servers.

Websocket library on Android

Novice here. Trying to setup websocket communications between an Android app and node.js on the server side.The problem I have is the lack of consensus on the Internets on which packages to use.On node.js- socket.io, often said to be stuck in the v0.9 version- engine.io- Autobahn.. and moreOn Android there are- https://github.com/koush/android-websockets-...

what kinds of JVM issues did you run into in deployment? for personal projects I have always used C++, Python, RoR, MEAN, etc. but at work where my role is non-dev, our software dev team likes Java and the heavy weighted GWT... frankly shutting me out. I'd love to know how to convince them to switch out of Java.
Re:Easy Steps to a Complete Understanding of SQL on Tuesday September 03, 2013 @05:38PM (#6323995)
Thank you for the examples.

I made some queries that are analogous to my temporal query needs

Here I'm looking for every student, other students with DOB within 2 weeks of the given student: http://demo.htsql.org/student.define(similar_students:=%20(s...

Here for every semester with at least one student, I find the oldest and the youngest students enrolled: http://demo.htsql.org/semester%20.define(starting_students:=...

No being a computer scientist I have to admit I do not appreciate the intricacies of the 'problems with SQL' blog entries. But working with htsql I gotta say it seems a lot more intuitive than SQL. It feels like the logic correspond much better to my mental model. And that there is much less of the jumping up and down the code to nest my SQL code logic that I find myself doing all the time.

Is there a way to install this on a PostgresQL instance on Win8?

Re:Easy Steps to a Complete Understanding of SQL on Tuesday September 03, 2013 @12:21PM (#6321810)
I have found SQL to be cumbersome for expressing temporal relationships, eg find all the event As that happen within one week of event B. There's not necessarily a data schema link between the table for event A and the table for event B.

how does htsql do with this?

Re:I’m Thinking. Please. Be Quiet. on Sunday August 25, 2013 @09:57PM (#6274722)
interesting! that seems to be consistent with my experience. I can never work at my quiet office where just sitting down bores me to tears and puts me to sleep in less than an hour. working at a cafe on the other hand I can go on for hours.

Do you have more info on the introvert/extrovert link?

Source? I don't think this is the case

Re:Yesterday I Wrote My First Firefox OS App on Monday August 12, 2013 @09:18AM (#6199001)
great points. I've been a big fan and advocate of android for some time. But I've have been disappointed and still am disappointed by how much hardware is necessary to run even basic tasks like getting onto the Internet and reading a static page, how even scrolling through the basic launcher interface stutters, even on the new nexus 7, how switching between apps can take so much time.

it seems that Android as a solution to the problem of a mobile phone is overshooting a big chunk of the market. in that sense I think FxOS is in a good position to disrupt the mobile space.

now how can I get my hands on a phone??

what are some issues you observed?

Open source alternative to FireBase?

From my limited experience with the tutorials, I'm a big fan of FireBase. I wish I could use their framework and their service. Unfortunately since I'm in the healthcare space, it's a much higher burden to justify, in terms of business and in terms of regulatory compliance, entrusting so much protected information to an outside entity.Are there alternatives similar to FireBase that we could...

Help with day job: Algorithmic staff scheduling solutions?

At a gross level, the problem is simple: schedule an army of staff for one-person-per-day coverage, at any given day the staff is split into 3 pools, each staff has a vacation requirement, each staff has at most 2 shifts per week, etc.I'd hate to do this manually as it has been done at my organization for centuries. I'd love to do something cool like genetic algorithms (eg...

Re:Where Google AppEngine beats AWS on Sunday June 01, 2008 @10:48AM (#205881)
From teh pov of small teams, I think the most important difference is that GAE takes care of systems maintenance completely. No worries about having someone on call to fix the server, to monitor load, to periodically patch the server software. That is one less systems administrater needed, which can be a significant cost.

The problem with GAE as many have pointed out is being locked-in to the GAE architecture. I'm betting on open source systems built on top of AWS, specifically scalr. Can anyone comment on their experiences with scalr?

"3. The a priori likelihood that your site will be popular enough to demand the scalability GAE can apparently deliver is very low, indeed nil. Are you willing to pioneer on an inconsistent infrastructure when you could use a proven relational one?"

The perceived probability of "getting popular enough" is for most start-ups non-zero. Else many start-ups would not even exist at all. That is, the expected value of the entire start-up endeavor, E(start-up)--say in the unit of dollars--is driven by these rare, but extreme outcomes.

Given this is the case, my impression is that: P( failure to scale | RDBMS ) > P( failure to scale | BigTable/simpleDB ) (that is, it is much more difficult to scale up RDBMS than BigTable/SimpleDB)

and P( success | failure to scale ) is near 0,

then it makes sense to prepare for that possible rare outcome of having to scale, in order to preserve that expected value.
