Simple Guidelines to prolong lithium based batteries

  • Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
  • Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges.
  • Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
  • Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
  • Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
  • Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
  • If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

Windows 7’s ‘GodMode’

By creating a new folder in Windows 7 and renaming it with a certain text string at the end, users are able to have a single place to do everything from changing the look of the mouse pointer to making a new hard-drive partition.

To enter “GodMode,” one need only create a new folder and then rename the folder to the following:

GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}

Once that is done, the folder’s icon will change to resemble a control panel and will contain dozens of control options which is a handy way to get to all kinds of controls.

The trick is also said to work in Windows Vista, although some are warning that although it works fine in 32-bit versions of Vista, it can cause 64-bit versions of that operating system to crash.

Setting up a git repository

Git is a free & open source, distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

First of all we need to install git on the remote server (lets call it server.com). The easiest way is to use yum to download and install the git software. The command is yum install git. yum will download all necessary files including dependencies if needed and … install the base git software.
