Usenet Binaries on iPhone/iPad (iOS5)

Why isn’t there a usenet binary downloader for the iphone or ipad?

I read over on sabnzbd’s forum that they are avoiding such an app because of battery issues. I have no problem plugging in if it means I can download on the go without having to bring a computer. This has already been done with torrents (even without jailbreaking): http://www.redmondpie.com/how-to-download-torrents-on-iphone-ipad-without-jailbreaking-tutorial/

I’m sure there would be a number of people willing to pay through Cydia to getting a working usenet binary downloader.

Please post a comment if you have any insight into why such an app hasn’t been created.

SN2 SN1 E1 E2 Subtitution and Elimination

Elimination versus Substitution Reactions:

The first step to understanding SN2, SN1, E1, and E2 reaction mechanisms is to ask yourself two questions (CCSF, Dr. Pauly 2011):

  1. Is the leaving group on a primary, secondary, or tertiary substrate?
  2. What are the characteristics of the nucleophile/base (Strong or Weak)?

After you identify the substrate go to the appropriate section below. Then, using a pKa table with conjugate bases (I’ll upload one soon), determine if your regent is a strong nucleophile and/or base. Read the rest of this entry »

Tea houses and tunes

I just listened to the new SaReGaMa album Fractal Universe: http://www.jamendo.com/en/album/100284

The album is quite great. A few of the tracks took my mind back to a beautiful memory of sitting in a tea house in Prague with a very special friend. We would lay in the tea house listening to music, drinking tea, and eating snacks for hours on end. I have never been is such a peaceful place before or since.

Take a listen to the album and if you are ever in Žižkov in Prague make sure to stop at Cajovna Genesis: http://www.cajovnagenesis.cz/

iPhone iOS 5 Cydia White Icon

So…did you just jailbreak your amazing new idevice to find that cydia is just a white icon and won’t load? Well a goat is here to help. All you’ll need to turn off your idevice (iPhone 3GS, iPhone 4, iPhone 4s, iPad 1, iPad 2, iPod touch. Note that the iPad 2 and iPhone 4s are not yet supported for jailbreaking.) and load up redsn0w or whatever you used to jailbreak, set the program for “just boot” and follow the steps.

If you have any questions or if this fix worked for you, please leave a note in the comments.
