Text Editors

3.10.�Text Editors

Most FreeBSD configuration is done by editing text files. Because of this, it is a good idea to become familiar with a text editor. FreeBSD comes with a few as part of the base system, and many more are available in the Ports Collection.

A simple editor to learn is ee (1). which stands for easy editor. To start this editor, type ee filename where filename is the name of the file to be edited. Once inside the editor, all of the commands for manipulating the editor's functions are listed at the top of the display. The caret ( ^ ) represents Ctrl. so ^e expands to Ctrl + e. To leave ee (1). press Esc. then choose the “ leave editor ” option from the main menu. The editor will prompt to save any changes if the file has been modified.

FreeBSD also comes with more powerful text editors, such as vi (1). as part of the base system. Other editors, like editors/emacs and editors/vim. are part of the FreeBSD Ports Collection. These editors offer more functionality at the expense of being more complicated to learn. Learning a more powerful editor such as vim or Emacs can save more time in the long run.

Many applications which modify files or require typed input will automatically open a text editor. To change the default editor, set the EDITOR environment variable as described in Section�3.9, “Shells” .

Course Goals

At the end of the course you will have created a working market simulator that you can use to test your own investing strategies. You will understand the basic principles of Modern Portfolio Theory and Active Portfolio Management.

  • Understand electronic markets.
  • Understand market data.
  • Write software to visualize market data.
  • Write software to discover market data.
  • Create a market simulator.
Prerequisite Knowledge

Who this course is for The course is intended for people with strong software programming experience and introductory level knowledge of investment practice. A primary prerequisite is an interest and excitement about the stock market. You should have strong programming skills to succeed in this course. Here's a quiz you can take to see if you have strong programming skills compinvesti-prog-quiz

Who this course is not for If you already use advanced software tools such as Mean Variance Optimizers in your regular investing practice, you will probably find that you are "overqualified" for this course.

Software we'll use In order to complete the programming assignments you will also need to become familiar with basic Unix commands, and you must download and install a set of Python modules to your computer (including NumPy, SciPy, Pandas, and QSTK).For more information about installing the software you will need, visit QSToolKit_Installation_Guide. The software works well on windows and Ubuntu unix. Some people have success with MacOS, but that is not as strongly supported.


Course Textbook The textbook for this course is What Hedge Funds Really Do by Philip Romero and Tucker Balch. You can learn about purchase information here: [1]

Grading Policy The first week will have a multiple choice quiz and in the following weeks you'll have a programming assignment each week. A total score of 70% or higher will guarantee a passing grade in the course.

Expectations Participants are expected to:

  • Watch all lecture videos every week
  • Complete assigned readings in the textbook
  • Complete all weekly assignments if any
  • Complete all quizzes
  • Abide by the standards of academic honesty – plagiarism and any form of cheating will not be tolerated and will result in the removal of the participant from the course
  • Seek help if needed

Communication & Etiquette Please communicate with the instructor and staff via the online forums. Because there are so many students, it is not possible for us to respond individually to every question. We will be using Piazza for the discussion forums in this class. The link can be either found the left navigation bar or [2]. Written language will be primary means of communication. As such, there can be miscommunication as there is no intonation in these written communications. Please be positive, supportive and constructive in your comments and forum postings. Please avoid any rude comments about the fellow students and posting anything that might hurt the sentiments of others.

Enrolling This course is being run through Please visit the course site for details and to sign up:

Qstk homework 3-10

Odin is a utility software developed and used internally by Samsung which can be used to flash a Custom Recovery firmware image (as opposed to the Stock recovery firmware image) to a Samsung Android device. It is also used as a way of unbricking an Android device. There is no account of Samsung ever having officially released it, and is believed to be the result of an unintentional leak.
Odin is Windows only software, providing no support for other operating systems, though it is possible to use Wineskin on the Odin executable, allowing it to run on OS X.

Have fun flashing

I dug this up a few months ago in April for my Upgrading and Downgrading via Odin to preserve KNOX 0x0 and warranty. it features Auto-FOTA and Auto-PIT(altho unverified) was an internal Samsung release I grabbed from one of their servers. a search on XDA could have shown you that its been around :P

4.x-to-4.4.2-SAFEUP-or-DOWNgrade w Root&SafeStrap.
Odin 3.10 (The newest and best option for Odin.) SuperSu 1.94 (IN both a flashable thru Safestrap .zip and a .apk - thanks to Chainfire)

OTA. no type: Tool size: 802.5KB upload date: Apr-20-2014, 09:04PM

I dug this up cannot verify its the newest version or that it is real, pretty sure it includes Auto-Fota which I believe maybe a temp auto backup of the files odin will write over possibly temporarily stored in blk 22 not 100% sure as just searching for this new version yields 0 results until now. ini file has been modified to show support for i545 but this should be compatible with any phone already using Odin. Maybe referred jokingly as gogOdin

Spend less managing your data

The PowerVault MD3 10GbE iSCSI array series brings affordability to primary storage and allows you to add capacity and software as needed. It keeps your storage directly attached to your data infrastructure and is compatible with Microsoft® Hyper-V®, Citrix® XenServer® and VMware® ESX. In addition, the MD-series storage arrays support vSphere® Storage APIs for Storage Awareness (VASA). Simplify physical and virtual resource management with MD Storage Manager and PowerVault VMware vCenter™ Plug-In 5.0.

MD Storage Manager

With wizard-based array configuration and single-pane management, MD Storage Manager can alert you to problems and launch its recovery guru to automatically help troubleshoot and resolve issues.

VMware vCenter Plug-In 5.0

Monitor, manage, provision and optimize storage for performance and availability across your virtual infrastructure. You can also implement Storage Replication Adapters (SRA) to simplify management of disaster recovery with centralized recovery plans and VASA to create profiles that map to volumes and virtual machines.

Upgrade with the Premium Feature Key bundles that meet your priorities.

Data Protection:

Ensure your data is protected with Snapshot, VDC and Remote Replication.

High Performance:

Data is increasing at an alarming rate, but performance should not be impacted. This bundle includes the High Performance tier, SSD cache and the additional drive capacity license.

Speed recovery with Dynamic Disk Pools.

Dynamic Disk Pools (DDP) protect data by dynamically distributing data across pools of drives. In the event of a drive failure, DDP will identify the critical data and dynamically rebalance the data so the array can return to an optimal state faster than it would in the typical RAID environment. DDP can now support up to 20 disk pools and up to 120 SSDs.
