rohan404··on Engineer.ai raises $29.5M Series A for its AI+Humans software building platform
To be clear, the next client doesn't actually get it for free. The way it works is that we use pre-fabricated components in conjunction with an ESB in order to create what is essentially a base for developers to then fill in with customization and business logic. Think of it as a set of well structured libraries that can be automatically stitched together (with dependency management and merge conflict handling). We don't reuse a customer's business logic - that's what makes their app unique. So for every customer we build for, there will always be that human element of customization.

- Disclaimer, I'm a VP E at Engineer.ai

rohan404··on How Indian Americans Came to Run Half of All U.S. Motels
You could make the argument that startup founders who aren't taking a salary from their early stage startup are also performing "free, illegally so" labor.
rohan404··on Bitwarden – Open Source Password Manager
We evaluated Bitwarden to use as our company vault for shared accesses, however found OneLogin to have a better UI, additional functionality (especially when it came to syncing with our Google directory) and the price (for enterprise) wasn't too much less than OneLogin (which is negotiable anyways).
rohan404··on Effectively using AWS Reserved Instances
Not quite - the outdated price issue certainly exists for standard AWS RIs, however if you purchase convertible RIs then price reductions are applied.

Also bear in mind that the savings you get from RIs will generally outweigh the reduction in price of the instance.

rohan404··on Effectively using AWS Reserved Instances
One of the major issues we've seen with our customers is that many of them (especially startups and SMBs/SMEs) don't have the ability to dedicate a team to just managing their RI capacity. We've also seen enterprise customers optimizing up to 70% of their EC2 usage, but many of them have trouble ensuring a level of utilization due to rapidly changing infrastructure. I'd definitely argue that GCP has a better model for some use cases as it requires less active effort for optimizing billing, however if you manage your RIs on AWS effectively you can often get a better price. Looks like Azure has also gone down the same route as AWS, which is quite an interesting move on their part.

Disclosure: I head engineering/devOps at Engineer.ai - one of our products Cloudops.ai allows our customers to save up to 15% of their AWS bill without making RI purchases, as well as get discounted prices and additional flexibility (custom lock-in periods) for RIs they do wish to purchase. Feel free to reach out for information - my email address is in my about section.

rohan404··on Breaking a large AWS spend into understandable pieces
Shameless plug, but it was the lack of clarity that we had with our AWS bills that prompted us to build https://cloudops.ai

We've got a prepaid service that allows you to always ensure your AWS bill never goes above certain amount as well as flat discounts on your monthly spend

rohan404··on Blinded after applying contact lenses with wet hands
An anecdotal word of warning: I wore bi-weekly disposables as well for quite a few years and would repeatedly sleep in them. Never had dry eyes or irritation, however after a few years I developed tiny capillaries growing in my eye (corneal neovascularization), as it turned out they were not getting enough oxygen.

Supposedly if they continue to grow I could lose my eyesight, and they won't actually go away even if I stopped wearing lenses.

rohan404··on McDonalds India is leaking 2.2M users data
I suppose that whole incident with Weev and AT&T would serve as legal precedent.
rohan404··on Ask HN: What tools do you use for project management?
We initially used PivotalTracker for managing our development teams, and Trello to get a high level overview of project status as well as for planning. We're currently working on building our own version of PivotalTracker using a fork of CM42 (https://github.com/Codeminer42/cm42-central) for internal use.
rohan404··on Welcome Jared
Jared has truly been an inspiration for me.

Apart from being an extremely bright and insightful person, he is remarkably down to earth and gave me sound advice during a particularly rough patch in my life!

Congratulations Jared! I hope you enjoy your time at YC.

rohan404··on Google PDF Search: “not for public release”
Isn't this one supposed to be public information anyways?: http://www.oema.us/files/FBI-OFFICES.pdf
rohan404··on Buck: A high-performance build tool for Android
Did you guys end up integrating Buck into Android Studio or just running it command line?
rohan404··on Hacker tries to compromise and resell an internet-facing Linux server
Guess the intruder wasn't completely convinced that chmod works the first time around
rohan404··on A Closer Look at Android RunTime in Android L
Even loaded asynchronously, the calls for allocation still cause lag. Unless I am doing something incorrectly?
rohan404··on A Closer Look at Android RunTime in Android L
This is true, but for operations like loading images from disk for example, this is unavoidable. The best you can do is reuse memory instead of allocating whenever possible
rohan404··on A Closer Look at Android RunTime in Android L
There is a System.gc() call which is essentially what you described, but it doesn't help with allocations freezing the UI for memory intensive applications
rohan404··on A Closer Look at Android RunTime in Android L
It was pretty ridiculous, even on some of the most powerful hardware out there I still found animations to lag from time to time due to the GC_FOR_ALLOC calls! Ended up with a bunch of hacks to try to work around the issue, but none fully resolved it.
rohan404··on Ask HN: What book are you reading right now?
Long Walk to Freedom by Nelson Mandela!
rohan404··on Show HN: Words for Chrome – Smarter, safer web comments
The Google login is a bit too disconcerting for my liking. At the very least showing the url bar would've have been less unsettling.

Only by opening the chrome inspector was I able to verify that it was indeed a valid login page and not a phising attempt as it appears to be at a cursory glance.

rohan404··on Camels and humps: a retraction [pdf]
Was anyone able to find an online version of the test?

Edit: Closest thing I could find: http://vanisoft.pl/~lopuszanski/public/canihascs/

rohan404··on Ask HN: What projects are you working on?
This is product that really solves a need for me! Right now I use a google voice number that I have set to forward to my Canadian and American numbers, however I cannot have it forward to my Indian number or some of my other VOIP numbers. I get an error when I try to purchase a number though, so not sure if the functionality for that is completely built out. Either way, will keep tabs on this to see when I can switch over completely.
rohan404··on Show HN: Dominus – Multiplayer browser strategy game made with Meteor
Managed to invade a square that had 3 castles on it. Only got one of them as a vassal though, which was quite a disappointment.

The wool price was my doing. Bought a few million worth with my infinity gold
rohan404··on Show HN: Dominus – Multiplayer browser strategy game made with Meteor
The market seems to have glitched out. Grain was trading at 0 gold for a good few minutes.

Edit: My apologies, I appear to have broken the market further. I managed to raise the price of grain to infinity, then I sold one grain for infinity gold.

I've been waiting about 10-15 minutes for a response myself; guess it's not automated?

My apologies, further research into this indicates it is fake, and a lot of the text is actually pulled from here: http://www.dailymail.co.uk/home/moslive/article-2289607/Amaz...
rohan404··on Learning to Code vs Learning Computer Science
I completely agree; in my experience sorting algorithms were a precursor to learning asymptotic notation
