I am actually trying to clone a tool on my system and I am following their configuration steps link to that tool ( and every time I run brew install mongodb I get the following error. is there anyone who is familiar with this error and know how to fix it?

The first step is to install MongoDB on your machine. You can go on the official website, in the top menu, you will see Download. Click the Download link ( and then select the Windows version. You can download the 64 bits or 32 bits. In this tutorial of MongoDB we will use the MongoDB 64 bits for Windows. The file is about 132 megs and is a setup.

The installation is pretty straight forward. You can select the typical installation to have a basic setup. During the installation, you will have to accept to elevate the permission.

From here, it is time to open a Command Prompt with administration right. Let’s go in the folder we just installed MongoDB. Since we have installed the typical package with the 64 bits version, the installation should be in program file.

You can after that configure MongoDB. The next steps are taken directly from MongoDB documentation. You must create a directory to save the content. This...

Well I've a pretty complicated hardware and software combination, so I am explaining the background first. I have a Macbook pro mid 2012 model with OSX Mountain Lion. I am dual booting it with Windows 7. Now I want to try out Windows 8, so that I can replace Windows 7 with Windows 8. So to try out I am using Oracle's VirtualBox to create a virtual PC and using Windows 8 trial (64 bit). All the three OS are 64 bit.

Now when I load the Win8 ISO (the ISO is in a usb drive), and boot from it in the virtual OS, there's some strange message coming from virtualbox which is

The virtual machine window is optimized to work in 32 bit color mode but the virtual display is currently set to 24 bit. Please open the display properties dialog of the guest OS and select a 32 bit color mode, if it's available, for best possible performance of the virtual video subsystem.

and then there's a windows 8 blue screen which says

Recovery Your PC needs to be repaired.

And then...

pete > guides > linux > install in a virtual machine

NOTE: These instructions are not canonical. There are many ways of installing Linux, but this will get you a running system that you can play with.

Download the install media here.

Boot the virtual install media

Select your virtual machine from the list. Click "Settings". Select "Storage". Under the "Controller: IDE" heading, select the stylized DVD labeled "Empty". To the right, click the button with the stylized DVD. Select "Choose Virtual Optical Disk File..." Navigate to and select the install media. Click Ok.

Click the big green arrow labeled "Start".

You'll see a menu show up: hit Enter to select the default option, "Boot Arch Linux (x86_64)".

A bunch of opaque nonsense will fly by and eventually you'll be presented with a prompt that looks something like this:

Arch Linux 4.15.2-2-ARCH (tty1) archiso login: root (automatic login) root@archiso ~ # _

This tells you that...

In this tutorial, we'll walk through the process of installing an

Ubuntu Server

virtual machine in


. We'll then install open-ssh server on the server so we can access it from the host. I'll also be installing MongoDB in preparation for a database project.

We'll use Ubuntu Server our guest operating system for its relative ease of use and because there is already a large amount of support information that can be found online for its setup and maintenance in VirtualBox. I'll be using the 64-bit version of Ubuntu Server 14.04.3. Make sure you choose the version with the correct architecture for your system: 32 vs. 64 bit. Download a copy of Ubuntu Server from the link.

Before beginning the installation process of any virtual machine, it's always a good idea to check the hash value of the file you've downloaded to ensure its integrity. It is quite annoying to have to begin the process again because your download was corrupted in some way. You can...

MongoDB on Linux

Kernel and File Systems

When running MongoDB in production on Linux, you should use Linux kernel version 2.6.36 or later, with either the XFS or EXT4 filesystem. If possible, use XFS as it generally performs better with MongoDB.

With the WiredTiger storage engine, using XFS is strongly recommended for data bearing nodes to avoid performance issues that may occur when using EXT4 with WiredTiger.

With the MMAPv1 storage engine, MongoDB preallocates its database files before using them and often creates large files. As such, you should use the XFS or EXT4 file systems. If possible, use XFS as it generally performs better with MongoDB.

In general, if you use the XFS file system, use at least version 2.6.25 of the Linux Kernel. If you use the EXT4 file system, use at least version 2.6.28 of the Linux Kernel. On Red Hat Enterprise Linux and CentOS, use at least version 2.6.18-194 of the Linux kernel.

A while ago I tried to install Oracle 11g R2 Express Edition on a 64-bit Ubuntu machine. This proved to be not as easy as you would expect. There are many blogs and articles about this subject and I tried a number of them. Unfortunately neither of the instructions seemed to work completely on my machine. With the combined information from the authors, I finally got it to work and I’ll gladly share my recipe in this blog. I have also included the installation steps for SQL Developer en Java (which is needed to install SQL Developer) in this blog. The installation was performed on a Ubuntu 12.04 VM with the following software.

This cookbook works with exacty the herefore mentioned versions… be aware that if you try to install a different version of one component, the steps below may not work. For example newer version of SQL Developer may require a more recent version of Java.

Installing Java

We start with installing Java on the machine. My personal preference...

In this article, we will set up an Express.js app which can be a basic website. We will learn the basics of routes, views, Jade templates, and handling POST and GET requests.

Let's create an site to list MEAN stack items. We will call it MEAN Stack.

Express.js is a minimal and flexible Node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications. It is relatively minimal with many features available as plugins.

Express.js systems are highly configurable, which allows developers to pick freely whatever libraries they need for a particular project.

Express.js is a web framework based on the core Node.js http module and Connect ( connect/) components. The components are called middleware and they are the cornerstones of the framework philosophy configuration over...
