DC Console Using DC Console Application Design Software
DC Console Using DC Console Application Design Software DC Console is easy-to-use, application design software developed specifically to work in conjunction with AML’s DC Suite. Create. Distribute. Collect. Every LDX10 handheld computer comes with DC Suite, which includes seven (7) pre-developed applications for common data collection tasks. Now LDX10 users can use DC Console to modify these applications, or create their own from scratch. AML 800.648.4452 Made in USA www.amltd.com Introduction This document briefly covers how to use DC Console and the features and settings. Be sure to read this document in its entirety before attempting to use AML’s DC Console with a DC Suite compatible device. What is the difference between an “App” and a “Suite”? “Apps” are single applications running on the device used to collect and store data. In most cases, multiple apps would be utilized to handle various operations. For example, the ‘Item_Quantity’ app is one of the most widely used apps and the most direct means to take a basic inventory count, it produces a data file showing what items are in stock, the relative quantities, and requires minimal input from the mobile worker(s). Other operations will require additional input, for example, if you also need to know the specific location for each item in inventory, the ‘Item_Lot_Quantity’ app would be a better fit. Apps can be used in a variety of ways and provide the LDX10 the flexibility to handle virtually any data collection operation. “Suite” files are simply collections of individual apps. Suite files allow you to easily manage and edit multiple apps from within a single ‘store-house’ file and provide an effortless means for device deployment. -

The Ifplatform Package
The ifplatform package Original code by Johannes Große Package by Will Robertson http://github.com/wspr/ifplatform v0.4a∗ 2017/10/13 1 Main features and usage This package provides the three following conditionals to test which operating system is being used to run TEX: \ifwindows \iflinux \ifmacosx \ifcygwin If you only wish to detect \ifwindows, then it does not matter how you load this package. Note then that use of (Linux or Mac OS X or Cygwin) can then be detected with \ifwindows\else. If you also wish to determine the difference between which Unix-variant you are using (i.e., also detect \iflinux, \ifmacosx, and \ifcygwin) then shell escape must be enabled. This is achieved by using the -shell-escape command line option when executing LATEX. If shell escape is not enabled, \iflinux, \ifmacosx, and \ifcygwin will all return false. A warning will be printed in the console output to remind you in this case. ∗Thanks to Ken Brown, Joseph Wright, Zebb Prime, and others for testing this package. 1 2 Auxiliary features \ifshellescape is provided as a conditional to test whether shell escape is active or not. (Note: new versions of pdfTEX allow you to query shell escape with \ifnum\pdfshellescape>0 , and the pdftexcmds package provides the wrapper \pdf@shellescape which works with X TE EX, pdfTEX, and LuaTEX.) Also, the \platformname command is defined to expand to a macro that represents the operating system. Default definitions are (respectively): \windowsname ! ‘Windows’ \notwindowsname ! ‘*NIX’ (when shell escape is disabled) \linuxname ! ‘Linux’ \macosxname ! ‘Mac OS X’ \cygwinname ! ‘Cygwin’ \unknownplatform ! whatever is returned by uname E.g., if \ifwindows is true then \platformname expands to \windowsname, which expands to ‘Windows’. -
How to Dump and Load
How To Dump And Load Sometimes it becomes necessary to reorganize the data in your database (for example, to move data from type i data areas to type ii data areas so you can take advantage of the latest features)or to move parts of it from one database to another. The process for doping this can be quite simple or quite complex, depending on your environment, the size of your database, what features you are using, and how much time you have. Will you remember to recreate the accounts for SQL users? To resotre theie privileges? Will your loaded database be using the proper character set and collations? What about JTA? Replication? etc. We will show you how to do all the other things you need to do in addition to just dumping and loading the data in your tables. 1 How To Dump and Load gus bjorklund head groundskeeper, parmington foundation 2 What do we mean by dumping and loading? • Extract all the data from a database (or storage area) • Insert the data into a new database (or storage area) • Could be entire database or part 3 Why do we dump and load? 4 Why do we dump & load? • To migrate between platforms • To upgrade OpenEdge to new version • To repair corruption • To “improve performance” • To change storage area configuration • To defragment or improve “scatter” • To fix a “long rm chain” problem • Because it is October 5 Ways to dump and load • Dictionary • 4GL BUFFER-COPY • Binary • Replication triggers (or CDC) • Table partitioning / 4GL • Incremental by storage area 6 Binary Dump & Load • binary dump files – not "human readable" -

“Log” File in Stata
Updated July 2018 Creating a “Log” File in Stata This set of notes describes how to create a log file within the computer program Stata. It assumes that you have set Stata up on your computer (see the “Getting Started with Stata” handout), and that you have read in the set of data that you want to analyze (see the “Reading in Stata Format (.dta) Data Files” handout). A log file records all your Stata commands and output in a given session, with the exception of graphs. It is usually wise to retain a copy of the work that you’ve done on a given project, to refer to while you are writing up your findings, or later on when you are revising a paper. A log file is a separate file that has either a “.log” or “.smcl” extension. Saving the log as a .smcl file (“Stata Markup and Control Language file”) keeps the formatting from the Results window. It is recommended to save the log as a .log file. Although saving it as a .log file removes the formatting and saves the output in plain text format, it can be opened in most text editing programs. A .smcl file can only be opened in Stata. To create a log file: You may create a log file by typing log using ”filepath & filename” in the Stata Command box. On a PC: If one wanted to save a log file (.log) for a set of analyses on hard disk C:, in the folder “LOGS”, one would type log using "C:\LOGS\analysis_log.log" On a Mac: If one wanted to save a log file (.log) for a set of analyses in user1’s folder on the hard drive, in the folder “logs”, one would type log using "/Users/user1/logs/analysis_log.log" If you would like to replace an existing log file with a newer version add “replace” after the file name (Note: PC file path) log using "C:\LOGS\analysis_log.log", replace Alternately, you can use the menu: click on File, then on Log, then on Begin. -

21Files2.Pdf
Here is a portion of a Unix directory tree. The ovals represent files, the rectangles represent directories (which are really just special cases of files). A simple implementation of a directory consists of an array of pairs of component name and inode number, where the latter identifies the target file’s inode to the operating system (an inode is data structure maintained by the operating system that represents a file). Note that every directory contains two special entries, “.” and “..”. The former refers to the directory itself, the latter to the directory’s parent (in the case of the slide, the directory is the root directory and has no parent, thus its “..” entry is a special case that refers to the directory itself). While this implementation of a directory was used in early file systems for Unix, it suffers from a number of practical problems (for example, it doesn’t scale well for large directories). It provides a good model for the semantics of directory operations, but directory implementations on modern systems are more complicated than this (and are beyond the scope of this course). Here are two directory entries referring to the same file. This is done, via the shell, through the ln command which creates a (hard) link to its first argument, giving it the name specified by its second argument. The shell’s “ln” command is implemented using the link system call. Here are the (abbreviated) contents of both the root (/) and /etc directories, showing how /unix and /etc/image are the same file. Note that if the directory entry /unix is deleted (via the shell’s “rm” command), the file (represented by inode 117) continues to exist, since there is still a directory entry referring to it. -
