Opnfv.org has released their debut version “Arno”, 3 months ago.

תחזית ההשקעות שלי לשנת 2015

שנת 2014 הולכת ומסתיימת, והגיעה העת לבצע כמה הימורים על ה”סוסים” החדשים לשנה הבאה.
שנת 2014 היתה שנה מאד קשה לסוחרי המגמה ומשקיעי מניות הצמיחה. ניתן לראות כי מניות החלום, אלו שכיכבו קודם לכן, השיגו תשואות שליליות (ואף מאד), כאשר רוב המדדים רושמים עליות נאות. על מניות אלו, ניתן נמנות את: DDD, FSLR, HIMX, AMZN, TWTR, GTATQ ועוד. השנה, לרוב המשקיע הפשוט, שקנה את המדדים, הרוויח יותר ממשקיעים מתוחכמים שביצעו מהלכים רבים על מניות ספקולטיביות.

How to track your android phone

Ever lost your android phone ? don’t remember where you left it ? or just want to track you r friends phone ?
If you have access to it’s Google account, you can track it without ever installing any tracking application. This is simply done with Google device manager

Requirements:

  • Your device is connected with your Google account.
  • Your device has access to the internet.
  • Allowed Android Device Manager (ADM) to locate your device (turned on by default). This can changed in the Google Settings app.
  • Allowed ADM to lock your device and erase its data (turned off by default).

You can even ring your phone in case you want to find it, or even wipe it’s data and lock it, if you pre-enabled that.
If you don’t have a browser, you can install the Google device manager app, and locate your phone from a different android phone.
Still this is not enough to deal with a bit more sophisticated thief, as if he disconnected the WIFI, or logged out from it’s Google account you won’t be able to locate your phone.
Even though, this is a nice feature to find your phone, which get lost sometimes.
For better tracking and locking features, you can always download a dedicated app from the app store.
