  1. Salut Am si eu o problema cu yii framework,am creat un tabel am generat modelul,am adaugat 4 coloane noi in tabel,dar nu le vad in model,daca apelez $model->coloana zice ca coloana nu e definita. In model am foarte multe functii custom nu pot sa il regenerez,nici sa folosesc diff. Cum pot sa adaug manual coloana in model,am adaugat numele coloanei in AttributesLabels() si rules() dar eroarea persista.

  5. Forget the trial and error - maths has now proved where the best spot to place your router is. Physics PhD student Jason Cole, from the Imperial College London in the UK, has figured out a formula that can work out the best place to position your wireless router, and it ultimately depends on your house's floor plan. As Greg Seals explains for The Daily Dot, Cole started investigating the science behind router placement in an attempt to optimise his wifi signal. To do this, Cole first mapped his floorplan, assigning refraction values to the walls, and then used the Helmholtz equation, which allowed him to model the electromagnetic waves being emitted by his router. Over on his blog Almost Looks Like Work, Cole describes the tricky mathematics that followed (bonus points if you can follow that equation). Initially, he came up with the not surprising solution that putting your router right in the middle of your home results in the best wifi signal. But, of course, it doesn’t necessarily look great to stick a router in the middle of the living room, and it’s not always feasible given power points etc. To investigate further, as Seals explains, Cole modified his model to take into account the absorption in wall materials such as concrete, and to stop perfect reflections forming a standing wave. This gave him a model that looked much more like wifi signals. Finally, he concluded what many of us already suspect - the further away you are from the router, the tougher it’ll be to try to catch the tendrils of signal. But if positioned properly, you can place your router in a spot that fills nearly every room of your house with beautifully oscillating waves of wifi, like in the video below. Cole has now even created an Android app that lets you map your own wifi signal around your house, to help you work out where your router should go (without the need for pages of formulae). You're welcome. Watch a of the app in action below.
