Ask HN: Handling failed Android LVL lookups?
I am about to publish a 2nd paid app and am a little unsure how to go about licensing and [basic] piracy protection.

With my first app I made it very restrictive - a failed lvl query resulted in the app not working. Unfortunately the amount of false positives has been considerable, but I had the luxury of being able to make old versions of the app obsolete with updates and trying various things over time.

The new app is going to be much more casual/simple, so I'd like to avoid any strict lockdowns. Its also not dependent on anything else, once its out, its out.

I'm wondering if anyone here has some experiences to share as far as handling failed purchase checks. The goal to is to deter the most causal of pirates - nothing fancy.
Ask HN: What's on Your Start Page?
I'm about to rework my start page. By Start Page, I mean the local html file that loads when I open a browse window.

Currently, I have:

SEARCH
Custom Duck Duck Go search box - defaults to local neighborhood, then everything.
Links to search engines - Wilby, Million Short...

MAGAZINES
Magazines and new information sources - like HN, Psyche, Nautilus, JSTOR, etc.

ENVIRONMENTAL DATA
Environmental - NOAA (sun, space weather)
Local weather - it's usually rain for nine months, and then drought for three. But I like the nuances.
Earthquake - I'm in the Puget Sound
ADBS & Marine Traffic - Military bases, shipping lanes nearby. One-click fun to see what's floating by.

IMPORTANT EVENTS
C-SPAN, NPR, NYT - I don't do news, but like to have links in case something !@! happens.

RADIO STATIONS
WFMU, WMFO, WEEU, WXAC, etc.
Tiny AM stations from Wyoming to Oklahoma have the best country music and on-air garage sales.
Couple web hosted RTL-SDR sites...

GOPHER / GEMINI
Gemini - Links to favorite sites like Gopherpedia and others.

LIBRARY
Bibliocommons, local and city sites, and subsites.
Very heavy library user, several times a day.

SERVERS & PROJECTS
localhost ports for site dev
Links to sites I have to monitor

My design is traditional two-column Yahoo! circa 1998. I'm always surprised how comfortable and easy it is to use. It was supposed to be a joke on myself, but I haven't had any inclination to change in three years. No images, black text on a dried mustard yellow.

So, I'm interested in how others utilize the start page. Specifically:

* Reminders, calendar?

* Tools or information sources?

* RSS or not - I use my email client now

* How do you manage / update your start page?

* Layout ideas, formats, templates...

* Images from your archives?

* Quote or fact of the day?

* Other categories, uses, purposes?

Thank you for sharing.

Hindsight analysis of the infamous DNS issue
http://vnhacker.blogspot.com/2008/07/analysis-of-infamous-dns-bug.html
If you use Metasploit, you can use the following formula to calculate your probability:

P_cs = 1 - (1 - xids/2^16)^A

where xids is the number of fake responses you want to send for each query. Remember to consider your bandwidth capacity when choosing xids. If you choose the default value, i.e. xids=10, then you can expect to poison successful after A>4000.
Anonymous functions and closures in PHP
http://www.zuttonet.com/articles/anonymous-functions-and-closure-php/
Hey HN! This is an article I wrote last night after trying to explain closures in PHP to a coworker. I wasn't really able to find a good "here's what they aren't, here's what they are" article on closures from a PHP perspective, so I decided to spend some time and create my own. I hope someone else finds it useful!
Show HN: Flipboard-like Hacker News web viewer

Yet another Hacker News web viewer, tried to mimic Flipboard experience.
Hacked for my own use. Primary use - iPad for 15 min before sleep. Secondary: iPhone 4 or workstation, depends, whenever got 5 min of time
Key features: 1. mobile friendly CSS and 2. Back end extracts text teaser and a pic for context. Got the only logo done entirely in CSS I know about :)
Status: a prototype - slow, scraping is only 70% good, Google App Engine might not be optimal for such an app, tested only on screens I use.
Goal: to find if such an app is appreciated by anyone but me. If yes - will be quickly improving. If no - will be slowly improving.
Motivation: I read HN a lot but not contribute articles, votes or comments. This is my way of paying back.

Ask HN: How did you solve the “messy office kitchen” problem?
I guess most of us know the problem of a messy office kitchen. Be it that the dishwasher is not filled or emptied, surfaces are dirty or full of used dishes, empty milk cartons are not disposed of, etc.

I've never worked in any office where this worked. Instead I regularly saw passive-aggressive notes or "Let's all work together" emails by office management that mostly got ignored.

Now my question is: has anyone successfully solved that issue? If yes, how did you actually pull it off?

Stadium food delivery. This is a great idea.
http://www.thefango.com/
"FanGo produces an iPhone app and mobile commerce ordering system that allows fans at stadiums and arenas to order concession food and drinks directly from their iPhone app. Food is then delivered to the fan’s seat, allowing fans to avoid long lines at food stands in stadiums. The startup is already in progress of negotiating deals with professional sports stadiums across the country."
Skymind launches with open-source, plug-and-play deep learning features
http://venturebeat.com/2014/06/02/skymind-launches-with-open-source-plug-and-play-deep-learning-features-for-your-app/
Deep learning essentially drives computers to make inferences like human brains do, based on the consideration of lots of information. It can be used to identify patterns and other traits in images, music, and text. A 24-year-old named Adam Gibson came up with open-source software called DeepLearning4j to do all those things; and today, Gibson is launching Skymind, a startup that will provide commercial support for the use of that software.

Beware Raising Money When Starting A Start-Up
http://publications.mediapost.com/index.cfm?fuseaction=Articles.showArticleHomePage&art_aid=66448
Our business is doing well yet again, and by our business I am referring to the Internet industry. As a result, there are numerous great ideas being explored and new companies being created, it seems like every week. But what I find most interesting is how many people are unwilling to bootstrap their ideas, and would rather spend 110% of their time trying to raise money, giving up 90% of their ideas, rather than focusing their attention on building out the core ideas for their business! ...
A real-time, customizable, embeddable chat system I built only using JS/Node.js
http://www.literoomjs.com
I thought it would be nice to have an easy way to create and embed a chatroom for any website/web app.

It's also possible to dynamically create rooms to offer privacy to users, since the chatroom is just accessed from a url.

It's nothing fancy yet, but for someone who wants real-time chat with almost no effort, this does the job.

Inspirational reading for those rejected for YC
http://www.paulgraham.com/hs.html
I actually stumbled across this yesterday, but didn't post it for fear of seeming try-hard or as a suck-up so close to the YC announcements. I guess that violates the principle of not caring what most people think.

This has probably been posted before, but either way, it's one of the most inspirational and practical articles I've ever read and well worth revisiting.

If anyone has any more articles like this to share (or re-share) today, I'd love to hear them.

Ask HN: What are the little things that annoy you in life?
I mean the tiny things that get on your nerves. My HN November Launch, Minklinks was inspired by not wanting to leave the web page when I share a link (and by Instapaper's bookmarklet).

Recently this has encouraged me to look for more areas of niggly things that could be made better. For example, my bank wants me to fill in a complicated form to be able to make international payments. I had to wait two weeks for the form, then fill it in, send it back and then wait two weeks for acknowledgement.

What in your life gets your goat, or at least thinking, "Surely there must be a better way?"

Show HN: Use Alexa and two smart thermostats for energy efficiency
https://gitlab.com/-/snippets/2433392
I wrote this up because oil prices are high and it definitely helps. This is a no-code solution to getting two thermostats to interact via alexa, if-this-then-that, and their respective smart applications. It's a quick and dirty hack, but I've been running it for about a month now and it's Just Worked. Also nice is that since the whole thing is controlled via Alexa, I can yell at my phone and have it tell me about the status of things.

I would love to know if there's an actual way to audit the costs of this aside of guessdimates, but without some fancy way of figuring out how well my baseboard radiators convert "burning oil" into "usable heat", it's going to be a guess at best.

Hopefully this helps HN save some coin. Please feel free to send the link to anyone else who might need it too.
