Vagrant

Create and configure lightweight, reproducible, and portable development environments.   Vagrant   is an amazing tool for managing virtual machines via a simple to use command line interface. Before you start In order to simplify the installation process you should install homebrew-cask which provides a friendly homebrew-style CLI workflow for the administration of Mac applications distributed as binaries. Refer to   this   article in order to install homebrew-cask. Install Vagrant uses   Virtualbox   to manage the virtual dependencies. You can   directly download virtualbox   and install or use homebrew for it. $ brew cask install virtualbox Now install Vagrant either   from the website   or use homebrew for installing it. $ brew cask install vagrant Vagrant-Manager   helps you manage all your virtual machines in one place directly from the menubar. $ brew cask install vagrant-manager Usage Add the Vagrant box y...

Ansible configuration file

Note:   Only 1 configuration file is processed. First one wins in the below list.   http://docs.ansible.com/ansible/intro_configuration.html ANSIBLE_CONFIG (an environment variable) ansible.cfg (in the current directory) .ansible.cfg (in the home directory) /etc/ansible/ansible.cfg

Why Is My SSD Capacity Smaller After Cloning?

When cloning from a smaller hard drive to a larger solid state drive, there is potential for system recovery partitions to prevent the cloning software from properly scaling your C: drive. If this happens, you’re essentially left with a recovery partition that’s eating up a majority of the drive’s space, as the screenshot in Disk Management below illustrates. Typically, a recovery partition should only be around 10-15GB. The recovery partition might not always be visible in Windows® Explorer, so you might need to go into Disk Management before you can see it. Because the cloning software couldn’t alter the recovery partition during the cloning process, you can’t go into Disk Management and shrink the recovery, then expand the C: partition to have a more appropriate size. The recovery partition will have some sort of security permission settings, or some service using the partition, which will...

How I cloned the 64Gb eMMC to a 256Gb M.2 SSD

Yesterday I installed an ADATA SP600 M.2 SSD in my LapBook. Fitted ok. and worked fine. The ADATA SSD, when registered on their site, gets you a license for Acronis HD to clone the existing eMMC drive to the new SSD. But for some reason it wouldn’t work. It needs to restart the LapBook but then instead of loading Acronis it simply loads Windows again and nothing happens. (Later I noticed that Acronis creates some sort of UEFI partition called Acronis Loader. It appears it doesn’t set the boot priority in the LapBook EFI partition to it, so it won’t start. If you manually tell the BIOS to boot from that partition, it might work.) Also (this version of) Acronis cannot move or resize partitions. The eMMC has a recovery partition as the last partition, this partition needs to be moved to the end of the new 256Gb. disk and the free extra space on that disk needs to be allocated to the C: partion. So I looked further for free tools to do this. I used Macrium Free (version ...

Switched fabric

Switched Fabric   or   switching fabric   is a   network topology   in which network   nodes   interconnect via one or more   network switches   (particularly   crossbar switches ). Because a switched fabric network spreads network traffic across multiple physical links, it yields higher total throughput than broadcast networks, such as the early   10BASE5   version of   Ethernet , or most wireless networks such as   Wi-Fi . The generation of high-speed serial data interconnects that appeared in 2001–2004 which provided point-to-point connectivity between processor and peripheral devices are sometimes referred to as fabrics; however, they lack features such as a message passing protocol. [ citation needed ]   HyperTransport , for example, continues to maintain a processor bus focus even after adopting a higher speed physical layer. Similarly,   PCI Express   is just a serial version of PCI; it adhere...

Small form-factor pluggable transceiver

The   small form-factor pluggable   ( SFP ) is a compact,   hot-pluggable   network interface module used for both   telecommunication   and   data communications   applications. The   form factor   and electrical interface are specified by a   multi-source agreement   (MSA) under the auspices of the   Small Form Factor Committee . [1]   It is a popular industry format jointly developed and supported by many network component vendors. The advantage of using SFPs instead of fixed interfaces (e.g.   modular connectors   in Ethernet switches) is that the interface port can be equipped with any suitable type of transceiver as needed. An SFP interface on   networking hardware   is a modular (plug-and-play) slot for a media-specific transceiver in order to connect a   fiber optic   cable or sometimes a copper cable. [2]   SFP transceivers exist supporting   SONET ,   Gigabit E...
