Solved Windows 8.1 80072f8f Update or Store error

Written by iassael on . Posted in computing

After spending a whole night getting the 80072f8f and trying all the amazing Microsoft tutorials and diagnostics finally I found a solution.
First of all, I didn’t have a problem with time (of course) nor SSL certs and such stuff. The problem was clearly the permissions of some dirs, and affected both most of my Metro apps and Windows Update. (this meant less restarts for updates for a month and its not that bad)

The problem can be solved easily by just downloading the amazing Tweaking.com Windows Repair (all in one)
http://www.tweaking.com/content/page/windows_repair_all_in_one.html

Just download the application click on all checkboxes and let it run for 3 hours, reboot and you are ready 🙂

Cheers~

Enable “Unknown Sources” via adb

Written by iassael on . Posted in android, computing

Getting a Nook SimpleTouch I had to enable the android option Unknown Sources via adb shell… so first connect with usb and make sure adb debugging is on…

  1. adb pull /data/data/com.android.providers.settings/databases/settings.db

  2. sqlite3 /path_to_your_folder/settings.db

  3. update secure set value=”1″ where name=”install_non_market_apps”;

  4. .quit

  5. adb push settings.db /data/data/com.android.providers.settings/databases/

Homebrew: ruby bad interpreter: No such file or directory

Written by iassael on . Posted in computing, macosx

After installing 10.10 DP1 Yosemite (yeah I couldn’t resist the temptation) homebrew gave me the following error:

/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory

This error can easily be fixed in the following steps:
1) Open terminal

2) nano /usr/local/Library/brew.rb

3) In the first line change “1.8” to “Current”, so it should look like this:

#!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0

Java can be very efficient sometimes… First, you need to to download the apache commons lang library, from here http://commons.apache.org/proper/commons-lang/. Then, using this function you can convert your List<>
double[] arr = ArrayUtils.toPrimitive(arrlist.toArray(new Double[arrlist.size()]))

The following solution is for google chrome and uses the “verbatim” search tool to acomplish the good old functionality.

Chrome Spelling for non System Language MacOSX

Written by iassael on . Posted in macosx

chrome logo

In order to make chrome check your spelling for a different language rather than the system’s (in this example Greek) you can run the following command in your Terminal.app

defaults write com.google.Chrome AppleLanguages ‘(el-GR)’ 

Για να ενεργοποιήσετε τον ορθογραφικό έλεγχο για Ελληνικά ενώ τα Αγγλικά είναι η προεπιλεγμένη γλώσσα του συστήματος σας εκτελέστε την παραπάνω εντολή στο Terminal.app . Δυστυχώς αλλάζει και η γλώσσα εμφάνισης του Chrome αλλά ενεργοποιείται ο ορθογραφικός έλεγχος ΕΠΙΤΕΛΟΥΣ!!! (:
