rentzsch.tumblr.com: Magic Feet

The experiment:

Step on a nail. Make sure it punctures your shoe and penetrates your foot.

(You probably want to make sure you’re up-to-date on your tetanus shot first.)

Do it again. Yes, with the blood. Doesn’t matter if you wait a week or a couple of years in-between runs.

Now the fun starts.

On the third run, you’ll catch yourself.

You’ll develop what roofers call “magic feet” — you’ll learn to recognize the sensation of a nail driving through the sole of your shoe.

I have magic feet.

And I just took a screenshot of my unsaved work as an app crashed.

That’s probably the closest software analog to magic feet.

Sometimes, an app starts to beachball mysteriously. Most often it’s Safari. It’s a special kind of beachball. You can feel that it will lead to a crash. Cmd-shift-3, open TextEdit, start typing whatever you were typing in Safari into TextEdit manually copying the text, watch Safari crash, reopen, open windows from last session, paste from TextEdit. The only thing that saved your work was an ungodly slow cache miss because your harddrive sucks.

I should just get MarsEdit. And a harddrive with a speed switch.

Howto: Restore Springboard icon positions after iTunes botches them

You’re syncing from another computer. You’re restoring from a backup. iTunes has a bad day. Whatever reason, iTunes decided to resync all your apps, and replace them in your springboard in alphabetical order. I don’t know about you, but I don’t find that particularly helpful. I don’t know *how* many times I’ve meticulously sorted at least the three first Springboard pages with my most often used apps (which doesn’t sound like much, but *damn* does that UI suck!).

Expert instructions
Get your ~/Library/Preferences/com.apple.springboard.plist from your old device or a backup, and replace the plist on your new device or new install. Nothing of much importance is in that file, so it should be fine to just replace. If you’re worried, just open the two files in Property List Editor and copy the array over; it’s just an array of array of application identifiers under the keypath iconState.iconLists. Respring/`killall SpringBoard` when done.

Noobie instructions
Scenario: You have a recent backup of your phone/pod/pad in Time Machine. You have your device with the botched icon ordering. You want to fix things.

  1. Make a backup of your device. This way, we will know relatively certainly which backup belongs to this particular device.
  2. In Finder, navigate to your home folder > Library > Application Support > MobileSync > Backups
  3. Sort by Modified, newest at the top. The topmost one (something like “74e39ee0ac6b69af6f57e213cf5c6b95e5fd787f”, perhaps longer and with dashes) will be your device’s backup. Move this one to your desktop.
  4. Enter Time Machine for this folder. Restore the folder you moved away before to yesterday’s version or something
  5. Download the iPhone Backup Extractor app
  6. Open that app, click the button, choose the name of your device with the most recent date, and confirm
  7. At the bottom, there is an “iPhone OS Files” entry. Extract this to your desktop.
  8. Now, your device need to be jailbroken. If it isn’t already, get Spirit JB, run it, and jailbreak your device (it’ll only take seconds)
  9. If you just jailbroke your device, or if you don’t have SSH enabled, go into Cydia on your device, wait for it to restart, and then install OpenSSH. You must change your default password, or bad things invariably will happen.
  10. Get Transmit or another good SFTP client.
  11. Make sure you’re on the same wifi as your device.
  12. In your SFTP client, connect to (name of your device, with spaces replaced with dashes).local. My device is called Canvas, so I connected to Canvas.local. The connection method should be SFTP, the username should be ‘mobile’, and the password is your mobile password, as changed above or previously. By default it is ‘alpine’, but you REALLY SHOULD NOT USE THIS PASSWORD, as it means anyone can connect to your phone, and e g read and send SMSes.
  13. You’ll end up in your mobile user’s home folder. Navigate to Library > Preferences.
  14. From your desktop, get the file iPhone OS Files > Library > Preferences > com.apple.springboard.plist, and upload and replace the one on your device.
  15. Respring or reboot the device. Icon positions should be restored.

I haven’t tested the noobie instructions; just mail me at joachimb@gmail.com if they don’t work and we’ll figure it out.

Maxwell's Equations

science:

Irregular Webcomic:

Imagine you are James Clerk Maxwell, in 1865, formulating your theory of electricity and magnetism, and writing down your four equations for the first time in history. You write down the terms of these equations based on your experiments with electric batteries, bits of wire, and magnets. (…) You take the values you measured for εo and μo, multiply them together, take the square root, and then take the reciprocal. The answer is a speed, so it has units of speed, in this case metres per second. And the answer is very close to 300,000,000 metres per second. Converted into miles, that’s a tad over 186,000 miles per second. Being James Clerk Maxwell, and a brilliant physicist, you immediately recognise what this number is.

The speed of light. (…)

When you were writing down your equations, you were thinking about electricity and magnetism. Light was the farthest thing from your mind. You had not the slightest clue (and nor did anyone else) that light was related to elecricity or magnetism. But there it is, falling out of your equations.

You realise that you are the first person in all of history to know what light is made of. Can you imagine that feeling?

We’re having a coding party at Voxar’s place. Sterd got bored of his game. I trololol’d him. He fired up Live and trololol’d me harder than I’ve ever been trololol’d before. (I can’t stop looping!)

Clarification

rentzsch:

It’s not about Adobe.

It’s not about Flash.

It’s not about cross-platform.

It’s about less code.

It’s about fewer crashes.

It’s about faster-than-C runtime.

It’s about faster development time.

It’s about distributed computing.

It’s about pervasive multicore.

It’s about REPLs and live software.

It’s about software that preemptively exposes my coding errors.

It’s about better software.

“

Every time you do something that’s hard for you, every time you transcend some personal boundary or cross some goalpost you thought uncrossable or work really fucking hard at something (even — especially — if you fail) or do something you thought you couldn’t do, it is an accomplishment, and it’s important to acknowledge it. Every time you receive a compliment and say “thank you” instead of “oh, it’s nothing”, you are striking a blow against a poisonous, toxic, and dangerous social model. And every time you do that publicly, you give strength to someone else who sees you do it, because by accurately valuing your accomplishments and achievements as accomplishments and achievements, you teach others that their similar accomplishments and achievements are things to be valued — and thus, by extension, that they are to be valued.

And every time you see someone trying to downplay their achievements, especially compared against someone else’s, remind them that accomplishment is not a zero sum game: your achievement doesn’t reflect upon another’s, and another’s doesn’t reflect upon you. Measure against yourself. That’s the only standard that matters.

And if you’re one of those people who are policing the social appropriateness of claiming one’s accomplishments and placing value upon them in public, just fucking stop it already.

There’s a very old bug on Adobe’s JIRA bug tracker about flash video performance being absolutely abysmal on MacOS. One of the QA engineers at Adobe commented a while ago on that issue to explain that Adobe was currently focusing all their effort on mobile devices, and “didn’t have time” to fix the Mac version. There was an uproar, and the comment was removed. As I have the original in my mail, I thought I’d repost it here for posterity:

Original comment: 
Hi everyone, 

We are well aware of this issue and there is already several bugs logged in our internal system. As with all bugs, they will be worked on based on priority. 

I know how you all feel; it pisses me off to see h.264 streaming video such as ones from hulu.com take up 70-80% cpu usage on a MAC (PC uses about 30%). It heats up my MAC, drains my batteries, and lags for a second once in a while when streaming in 420p quality. 

What can be more important than fixing this MAC specific performance issue you ask? If you do a search on Google or have went to the recent MAX conference, you will understand that our highest priority will be optimizing our player to be faster than ninjas for mobile phones (http://news.cnet.com/8301-1001_3-10098883-92.html) 

If you were CEO, what would you do? Spend resource to fix this bug (it's not like it doesn't work- it's just not as good as PC) to make a million people happy, or give Flash to everyone with phones (billions of people?). 

These MANY INSANE "optimizations and new technology" will fix many performance issues; and perhaps, this one included. 

With all that said, I'll continue to push this bug to be fixed. I would fix this bug myself if I could... 

Please be patient.

On ngmoco’s We Rule

We Rule is a pretty boring FarmVille knock-off for iPhone and iPad. Actually, it’s really well made for what it is: nice graphics, music and atmosphere. But all you do is plant, harvest, order and deliver. I figured, maybe I can enjoy it anyway? One of the results from that is the image below.

It’s obvious ngmoco are rewarding people who spend as much time as possible in the game. The fastest way to get money is to plant the fastest crop, so that you’ll have to constantly stay in the game — 6 coins per minute. The casual gamer might plant beans and return once a day, but only get 0.3 coins per minute.

Seeing someone with a nice kingdom doesn’t mean that they are dedicated, however. If you give ngmoco real, actual money and buy ‘mojo’, they’ll shorten any waiting time to mere seconds. I understand that this is their entire business model, but I feel it takes away from any sense of accomplishment of doing things the non-paying way.

What really annoys me is what this game could have been. The makers of the game, Newtoy, helped make Age of Empires 2, so obviously they know how to make non-casual games too. I tcpdumped the server traffic and got a json description of my kingdom, which was highly interesting. They planned for several kinds of resources: stone, food and wood, which would have made for a much more complex and interesting gameplay. The best part, however, is how the json hints at armies; infantry, archers, cavalry. This game would have been absolutely *kickass* if you could attack other players! Or attack anything at all, for that matter. There is also hints of trading, another absent feature.

Perhaps these features are scheduled for a future release? I dearly hope so, but I really doubt it. I imagine Newtoy had great plans for a social medieval strategy and city-building game, and came to Ngmoco for financing. However, Ngmoco must have found the game much too inaccessible to all the casual FarmVille gamers out there; what’s the fun in building if it can be torn down? And however do you get ROI on a freemium game without heaps and bounds of casual gamers? And thus did Kingdoms (production name) become We Rule.

(I’m nevyn on Plus+ btw, if you want to add me)
