Developing for iOS and Android: How do you deal with all those resolutions?

beta_crater · 2012-05-26T22:07:24.460171+00:00

FYI, there's only 4 iOS resolutions so far:

iPad: 1024x768 or 2048x1536 (2x original) iPod/iPhone: 480x320 or 960x640 (2x original)

Scaling is dirt simple.

With some creative UI adjustments, if you plan to do a Universal app, the iPhone 4S &amp; iPod Touch 4th gen and iPad 1 &amp; 2 pretty much have the same resolution. UI elements (different screen size = different size buttons) aside, you can re-use a lot of the same assets between them.

Making pre-scaled assets for iPad 3 may be overkill for your project since it's the only iOS device so far with a screen that big. Much easier to cheat for now and just let the OS auto scale it to 2x for you. Just focus on early gen iPhone/iPod and 2x that (with an alternate iPad UI).

Good luck finding any kind of sanity with Android.

They work fine as long as you have a properly grounded house / outlets. They communicate over the ground.

Plex, as a media player, was originally a Mac-specific fork of another older media player: XBMC

Unlike Plex, however, XBMC on iOS / Apple TV 2 continues to be a full fledged media player - doing all decoding of any video formats on the device itself, requiring no 'server' half running on another computer to do transcoding for you. All XBMC needs is the network share / directory to pull the files from. Are they all on your Mac / PC? Just turn on file sharing = good to go.

Mind you, it does work a little differently - its not as aggressive as Plex, for instance, at attempting to match your filenames with tv shows / movies.

The control scheme when using the remote can be a bit odd, but message me if you need tips.

You can jailbreak using the recently released Absinthe 2.0: http://greenpois0n.com/

Once you've done that, follow the short guide here on getting XBMC 11 installed:

(need to know how to ssh into your AppleTV but there's a link in the guide on that, too, if you don't know how)

Note: works with 5.1, not sure about 5.1.1 but it should be ok.

I use it on my AppleTV 1 which has an even worse processor/CPU and it works great :)

Considered XBMC instead? It gets regular updates.

LOL, sort of.

The Taiwanese stole a poor copy of the recipe from the Japanese.

It wasn't just Dell that was affected :)

And no, not every cap ends this way. Just those made during certain years from that area of the world.

If you're concerned about it, you can always go free on holidays / certain times of the year / because it's your cat's birthday / etc.

This also gets you the added bonus of appearing in most of the daily app deal finders with automated paid->free listings.

With the double bonus of a little regular halo boost of paid sales when it goes back to non-free.

Tip from a dedicated deal finder, though: some of the deal apps show pricing history over the past 90 days or even up to a few years. In addition they'll let you sign up for (Push) notification when the price changes. If you routinely game your pricing, people like me will a.) see it and b.) just wait until the next price drop. Keep it a rare occurrence.

For the total entropy of the password space, yes, minimum number of bits possible to represent all possible passwords.

oteren · 2 days

Link first: http://www.redkestrel.co.uk/Articles/RandomPasswordStrength.html

Plain English explanation:

Password you will definitely get in 1 try = zero 'guesses' required = zero bits to represent possible password states.

Password you could get in 2 tries = 1 guess = 1 TRUE/FALSE correct = 1 'bit' of password entropy vale.

So then you turn it around: how many such entropy bits would a password like this represent: single character password chosen from the 26 lowercase letters a through z.

The idea is: how many distinct choice A Or B picks in a row (bits) would it take to cover the whole pool of possible passwords? ie 2 choices * 2 choices * 2 choices ... How many times to get 26 possible single character passwords? How many bits would it take to represent 26 vales in binary?

Answer: log base 2 of (26) = 4.7

2 to the power of 4.7 = 26 possible passwords from that pool.

Expanding on it: 2 character password = 26*26 possible passwords.

Now where the benefit comes in: log2(26*26) = log2(26²⁾ = 2 * log2(26) = 9.4 bits of entropy / required to represent all possible passwords. Simple logarithmic math.

Entropy = what's required to represent it all.

A fully binary random bit password = 1 bit of entropy / value per bit.

A password of alphanumeric, all lower case = 5.17 bits per character (even though a computer uses 8 bits to store said character) to represent all possible passwords.

A password of alphanumeric, lower and upper case = 5.95 bits per character (even though a computer uses 8 bits to store said character) to represent all possible passwords.

This is basically a method of representing the equivalence of typed possible passwords to strength of a totally random binary key N bits in length.

Where everyone goes wrong in their "OMG SO INSECURE" analysis is that they're comparing possible password counts of equivalent character lengths at the "more" and "less" secure choice pool levels. No one is claiming they're of equal security. Instead, we're claiming 1 or 2 characters more = relatively same strength.

Example:

upper+lower+num, 7 characters = 3.5 trillion possible passwords

lower+num, 8 characters = 2.8 trillion possible passwords

lower+num, 9 characters = 100 trillion possible passwords

Umm. Unjailbroken iOS 5 user here.

Double-click home, slide finger from LEFT to RIGHT once:

iTunes controls and a soft rotation lock

Twice:

Volume level and AirPlay

No need for jailbreak for rotation lock. That's just silly.

Glad you got one :)

Honestly, at this point, the cost of the device or at least a portion of it should have been covered by insurance against theft.

Write the device off, you're not going to see it again.

If you really want traction on this, you're going to have to involve the local news with a story about how you've pretty much handed the address of the computer to the police and they still refuse to do anything. They love a juicy story like that.

But be warned: Everything you do / have done will come under scrutiny, and you could be exposing yourself to unintended lawsuits / legal issues.
