on: Grand jury subpoena for Signal user data, Central District of California
I don't know how Signal works but it is possible to send a silent encrypted push notification that the app can decrypt and show as a local notification.

on: Ask HN: How are you building cross-platform (mobile and browser) apps?
We use React Native for our apps and React for desktop - I'd say about 95% of the Android/iOS code is shared and we're able to share a lot of business logic between mobile and web. Having all of the code together in one repo has worked really well for us and some of the most complicated stuff is shared between all platforms.
If you want to share UI across platforms you could potentially use something like https://github.com/lelandrichardson/react-primitives to do that, but we don't and I'm not sure we'd want to because we don't want to use the same design on all platforms.

on: Checkboxes that kill your product
I find that a useful way to look at this is to compare the time you would spend on that to the growth you would get by spending time elsewhere.
For example if it takes 1 week to add support for JS disabled clients and they are 1% of your target market but you could spend a week on a feature that would likely add 2% growth, it's a pretty easy decision. The exact numbers are sometimes hard to work out, but the thought process can make the decision easier.

Possibly like me you have plugins disabled - it looks like it doesn't start until you enable Flash.

on: Startup idea list
I've been thinking about something similar to this - particularly for me in relation to when bands bring out new albums or new TV series come out. I was thinking I'd probably tackle it a vertical at a time and find a source for the information (e.g. last.fm for albums, IMDB for movies/TV series) that can be put to use automatically. I reckon the simplest way to monetize this would be affiliate links in the alerts - the click through is obviously going to be pretty high (people have actively said they're interested in something) but I've never seen affiliates as a great source of revenue.

on: Plop: Low-overhead profiling for Python
Definitely not! But we use it for testing locally, during which time we don't write pyc files which means we're less likely to have issues with that when we deploy to production.

on: Plop: Low-overhead profiling for Python
We've started running our runservers with pythondontwritebytecode=1 - I haven't noticed enough of a performance impact to change it back and it saves us remembering to delete pyc files before deploys.

on: Show HN: Facebook Open Graph Redirect Chrome Extension
The Guardian app (possibly UK only...not sure) redirects directly to the article if you click No and then remembers that you did that and redirects you directly from then on. Definitely the best implementation I've seen but I don't know the details about exactly how they did it.

on: Chrome addons hacking: Bye Bye AdBlock filters
Most people use ad networks and ad networks generally don't provide a way to get the ads on the server side. That would also be more complicated than sticking an iframe/script tag on the page for the publisher.
If you don't want to use a network, you have to sell the ads direct yourself - which isn't easy.

on: Why the cloud isn't for your startup
I think the important thing to take away from articles like this is that the cloud isn't the only way (not that you should then title the article "Why the cloud isn't for your startup"). If you do know a bit of sysadmin stuff and/or you're running a bootstrapped company it's good to know you can pay about 10% of what you'd pay on AWS by using dedicated gear (particularly if you have predictable traffic, as a lot of sites do). "X hours of my time is the same cost as Heroku" only works if you have cash in the bank or each hour of your time directly brings in cash.
We do have a slightly special case with >100TB of storage and monthly bandwidth, though. When we started I assumed S3 (or another cloud service) was the only way and never dreamed of building my own distributed file system.

on: Online services our startup subscribes to
I'm not sure about the automation of creating servers in the web interface (it gives you a key that you have to put in the configuration file) - installing the service is easy though through a package manager.
The two things I think are great about ServerDensity over Munin (haven't used nagios) are the snapshots (you click on a point in the graph and it shows you the processes running, server load, network etc at that time) and the alerting (email, Android, iPhone push) which is great. Even custom plugins are easy to write/install and stick alerts on.
