FSelector is a Ruby gem that aims to integrate various feature selection algorithms and related functions into one single package. Welcome to contact me (need47@gmail.com) if you'd like to contribute your own algorithms or report a bug. FSelector allows user to perform feature selection by using either a single algorithm or an ensemble of multiple algorithms, and other common tasks including normalization and discretization on continuous data, as well as replace missing feature values with certain criterion. FSelector acts on a full-feature data set in either CSV, LibSVM or WEKA file format and outputs a reduced data set with only selected subset of features, which can later be used as the input for various machine learning softwares such as LibSVM and WEKA. FSelector, as a collection of filter methods, does not implement any classifier like support vector machines or random forest.

= Simple task organizer syctask can be used to create, plan, prioritize and schedule tasks. ==Install The application can be installed with $ gem install syc-task == Usage syctask provides basic task organizer functions as create, update, list and complete a task. Additional functions are to plan tasks you want to accomplish today. If you are not sure in which sequence to conduct the task you can prioritize them with a pair wise comparisson. You can time tasks with start and stop and you can finally extract tasks from a minutes of meetings file. The schedule task command will print a graphical timeline of the working day assigning the planned tasks to the timeline. Busy times are marked red. Meetings are listed with associated tasks that are assigned to the meetings. With the statistics command you can print statistical evaluation of tasks duration and count. ===Create tasks with new Create a new task in the default task directory ~/.tasks $ syctask new "My first task" Provide a description $ syctask new "My first task" --description "Explanation of my first task" Schedule a task with a follow-up and due date $ syctask new "My first task" --follow-up "2013-02-25" --due "2013-03-11" Set a proirity for a task $ syctask new "My first task" --prio 3 Prompt for task input $ syctask new will prompt for task titles. Ctrl-D will end input. Except for --description you can also provide short forms for the options. ===Create tasks by scanning from files When writing minutes of meetings tasks that should be followed up in syctask can be annotated so they will be recognized by the scan command. The following structure shows how to annotade tasks Some text before @task; title;description;follow_up;due_date,prio Schedule meeting;Invite all developers;2016-09-12;2016-10-12;1 Write letter;Practice writing letters;;;3 Some text after The above annotation will only scan the next task because of the singular 'task' where the task values are separated with ';'. The line after the annotation '@task' lists the sequence of the fields of the task. It is also possible to list the tasks in a table, e.g. markdown Some text before @tasks| title |description |follow_up |due_date |prio ----------------|--------------------------|----------|----------|---- Schedule meeting|Invite all developers |2016-09-12|2016-10-12|1 Write letter |Practice writing letters | | |3 Some text after Call partner |Ask for project's progress|2016-09-14| |1 Even more text The example above scans all tasks due to the plural 'tasks'. It also scans all tasks that are separated with non-task text and occur after the annotation and confirm to the field structure. Lines that start with '-' will be ignored. So if you want to skip only a few tasks within a task list prepend them with '-'. If you have tasks with different fields then you have to add another annotation with the new field structure. Possible fields are title - the title of the task - mandatory field! description - the description of the task follow_up - the follow-up date of the task in the form yyyy-mm-dd due_date - the due-date of the task in the form yyyy-mm-dd prio - the priority of the task tags - tags the task is annotated with note - a note for the task Note: follow_up and due_date can also be written as Follow-up and Due-Date. Also case is ignored. As inidcated in the list the title column is mandatory. Without the title column scan will raise an error during a scan. Fields that are not part of the above list will be ignored. # | Title | Who - | ------------------------------------ | --- 1 | Schedule meeting with all developers | Me 2 | Write letter to practice writing | You In the table only the column Title will be scanned. The '#' and 'Who' column will be ignored during scan. This table is also a table for a minimum scan structure. You need at least to provide a title column so the scan function will recognize the table as a task list. Scanning tasks from files $ syctask scan 2016-09-10-mom.md 2016-09-09-mom.md ===Plan tasks The plan command will print tasks and prompts whether to (a)dd or (s)kip the task. If (q)uit is selected the tasks already added will be add to the today's task list. If (c)omplete is selected the complete task will be printed and the user will be prompted again for adding the task. Invoke plan without filter $ syctask plan 1 - My first task (a)dd, (c)omplete, (s)kip, (q)uit? a Duration (1 = 15 minutes, return 30 minutes): 3 --> 1 task(s) planned Invoke plan with a filter $ syctask plan --id "1,3,5,8" 1 - My first task (a)dd, (c)omplete, (s)kip, (q)uit? Move tasks to another days plan $ syctask plan today --move tomorrow --id 3,5 This will move the tasks with ID 3 and 5 from the today's plan to the tomorrow's plan. The duration will be set to the remaining processing time but at least to 30 minutes. ===Prioritize tasks Planned tasks can be prioritized in a pair wise comparisson. So each task is compared to all other tasks. The task with the highest priority will bubble on top followed by the task with the next highest priority and so on. $ syctask prio 1: My first task 2: My second task Task 1 has (h)igher or (l)ower priority, or (q)uit: h 1: My first task 2: My third task Task 1 has (h)igher or (l)ower priority, or (q)uit: l 1: My third task 2: My fourth task Task 1 has (h)igher or (l)ower priority, or (q)uit: h ... syctask schedule will then print tasks as follows Tasks ----- 0: 10 - My fourth task 1: 7 - My third task 2: 3 - My first task 3: 9 - My second task ... Instead of conducting pairwise comparisson the order of the tasks in the plan can be specified with the -o flag $ syctask plan -o 7,3,10,9 The plan or schedule command will print the tasks in the specified order Tasks ----- 0: 7 - My third task 1: 3 - My first task 2: 10 - My fourth task 3: 9 - My second task If only a part of the tasks is provided the rest of the tasks is appended to the end of the task plan. If you specify a position flag the prioritized tasks are added at the provided position. $ syctask plan -o 7,9 -p 2 Tasks ----- 0: 3 - My first task 1: 10 - My fourth task 2: 7 - My third task 3: 9 - My second task ===Create schedule The schedule command will print a graphical schedule with assigning the tasks selected with plan. When schedule command is invoked the planned tasks are added at or after the current time within the time schedule. Tasks that are done and scheduled in the future are not shown. Tasks done and in the past are shown with the actual processing time. Create a schedule with working time from 8a.m. to 6p.m. and meetings between 9a.m. and 9.30a.m. and 1p.m. and 2.45p.m. $ syctask schedule -w "8:00-18:00" -b "9:00-9:30,13:00-14:45" Add titles to the meetings $ syctask schedule -m "Project status,Management meeting" The output will be Meetings -------- A - Project status B - Management meeting A B xxx-///-|---|---|---///////-|---|---|---| 8 9 10 11 12 13 14 15 16 17 18 1 Tasks ----- 0 - 1: My first task Adding a task to a meeting $ syctask schedule -a "A:0" will print Meetings -------- A - Project status 1 - My first task B - Management meeting A B ----///-|---|---|---///////-|---|---|---| 8 9 10 11 12 13 14 15 16 17 18 Tasks ----- 0: 1 - My first task A task that is re-scheduled with $ syctask update 1 -f tomorrow will be shown as done (green) in the schedule and instead of separator - it shows ~. Tasks ---- 0: 1 ~ My first task A started task will be indicated by * $ syctask start 1 $ syctask sche Tasks ----- 0: 1 * My first task ===List tasks List tasks that are not marked as done in short form $ syctask list List all tasks in long form $ syctask list --all --complete Search tasks that match a pattern $ syctask list --id "<10" --follow_up ">2013-02-25" --title "My \w task" ===Inspect tasks Lists each unplanned task and allows to edit, delete, mark as done or plan for today or another day $ syctask inspect 0016 Create command for inspection (e)dit, (d)one, de(l)ete, (p)lan, da(t)e, (c)omplete, (s)kip, (b)ack, (q)uit ===Edit task Edit a task with ID 10 in vi $ syctask edit 10 ===Update tasks Except for title and id all values can be updated. Note and tags are not overridden rather supplemented with the update value. Update task with ID 1 and provide some informative note $ syctask update 1 --note "Some explanation about the progress on the task" ===Complete tasks Complete the task with ID 1 and provide a final note $ syctask done 1 --note "Finalize my first task" ===Delete tasks Delete tasks with ID 1,3 and 5 from the default task directory $ syctask delete --id 1,3,5 Delete tasks with ID 8 and 12 from the planned tasks of today. The tasks are only removed from the planned tasks and not physically deleted. $ syctask delete --plan today --id 8,12 ===Settings The settings command allows to define default values for task directory and to create general purpose tasks that can be used for tracking and later statistical evaluation. Create general purpose tasks for phone and talk $ syctask setting --general PHONE,TALK List all settings $ syctask setting --list ===Info Info searches for the location of a task and lists all task directories Search for task with id 102 $ syctask info --id 102 List all task directories $ syctask info --taskdir ===Statistics Shows statistics for work and meeting times as well as for task processing Evaluate the complete log file $ syctask statistics Evaluate work times, meetings and tasks between 2013-01-01 and 2013-04-14 $ syctask statistics 2013-01-01 2013-04-14 Evaluate yesterday and today $ syctask statistics yesterday today ===Task directory and project directory The global options --taskdir and --project determine where the command finds or creates the tasks. The default task directory is ~/.tasks, so if no task directory is specified all commands obtain tasks from or create tasks in ~/.tasks. If a project is specified the tasks will be saved to or obtained from the task directories subdirectory specified with the --project flag. --taskdir --project Tasks in - - default_task_dir x - task_dir - x default_task_dir/project x x task_dir/project In the table the relation of commands to --taskdir and --project are listed. Command --taskdir --project Comment delete x x deletes the tasks in taskdir/project done x x marks tasks in taskdir/project as done help - - inspect x x lists task to edit, done, delete, plan list x x lists tasks in taskdir/project new x x creates tasks in taskdir/project plan x x retrieves tasks to plan from taskdir/projekt prio - - input to prio are planned tasks (see plan) scan x x creates scanned tasks in taskdir/project schedule - - schedules the planned tasks (see plan) start - - starts task from planned tasks (see plan) statistics - - shows statistics of time and count stop - - stops task from planned task update x x updates task in taskdir/project ===Files * ID id file contains the last issued id. * IDS ids file contains all issued ids. * Task files The tasks are named ID.task where ID is any Integer as 10.task. The files are saved as YAML files and can be edited directly. * Planned tasks files The planned tasks are save to YYYY-MM-DD_planned_tasks in syctask's system directory. Each task is saved with the task's directory and the ID. * Schedule files The schedule is saved to YYYY-MM-DD_time_schedule in the default task directory. The files are saved as YAML files and can be changed manually. * Log file Creating schedule and task processings is logged to tasks.log. For example when a task is started and stopped this is action is saved to tasks.log. * Tracked file A started task is saved to tracked_tasks. A semaphore file is created with ID.track when the task ID is started. When the task is stopped the semaphore file is deleted. * General purpose tasks With syctask setting -g PHONE so called general purpose tasks can be created. These tasks can be used for time tracking and later statistic evaluation to determine the amount of disturbences e.g. by phone. These tasks are saved to default_tasks. The general purpose tasks itself are also saved to the .syc/syctask directory as regular task files. * Default task dir The default task that is used e.g. with list is saved to default_tasks_dir. This can be set with the setting command. ==Working with syctask To work with syctask and get the most out of it there is to follow a certain process. ===Creating a schedule ==== View tasks In the morning before I start to work I scan my tasks with syctask list or syctask inspect to get an overview of my open tasks. $ syctask list ==== Plan tasks Next I start the planning phase with syctask plan. If I have a specific schedule for the day I will filter for the respective tasks $ syctask plan ==== Prioritize tasks (optionally) If I want to process the tasks in a specific sequence I prioritize the tasks with $ syctask prio ==== Create schedule I create a schedule with my working hours and meetings that have been scheduled with $ syctask -w "8:00-18:00" -b "9:00-10:00,14:30-16:00" -m "Team,Status" ==== Create an agenda I assign the topics I want to discuss in the meetings to the meetings with syctask schedule -a "A:1,3,6;B:3,5" ==== Start a task To begin I start the first task in the schedule with syctask start -p ID (where ID is the ID of the planned (-p) tasks) $ syctask start -p 10 ==== End a task To end the task I invoke $ syctask stop This will stop the last started task ==== Re-schedule a task If I cannot finish a task than I update the task with a new follow-up date $ syctask update 23 -f tomorrow The task will be shown in the today's schedule as done. ==== Complete a task When the task is done I call $ syctask done 23 ===Attachements * E-mails If an e-mail creates a task I create a new task with syctask new title_of_task. The subject of the e-mail I prepend with the ID and move the e-mail to a <b>open topics</b> directory. * Files If I create files in the course of a task I create a folder in the task directory with the ID and save the files in this directory. If there is an existing directory I link to the file from the ID directory ==Supported platform syc-task has been tested with 1.9.3. It also works in Windows using Cygwin. ==Add TAB-completion to syctask To activate bash's TAB-completion following lines have to be added to ~/.bashrc complete -F get_syctask_commands syctask function get_syctask_commands { if [ -z $2 ] ; then COMPREPLY=(`syctask help -c`) else COMPREPLY=(`syctask help -c $2`) fi } After ~/.bashrc has been updated the shell session has to be restarted with $ source ~/.bashrc Now syctask followed by TAB TAB will print $ syctask <TAB><TAB> delete done list plan scan stop _doc help new prio schedule start update To complete a command we can type $ syctask sch<TAB> which will complete to $ syctask schedule ==Output to Printer To print syctask's output to a printer pipe the command to lpr $ syctask schedule | lpr This will print the schedule to the default printer. To determine all available printer lpstat can be used with the lpstat -a command $ lpstat -a Canon-LBP6650-3470 accepting requests since Sat 16 Mar 2013 04:26:15 PM CET Dell-B1160w-Mono accepting requests since Sat 16 Mar 2013 04:27:45 PM CET To print to Dell-B1160w-Mono the following command can be used $ syctask schedule | lpr -P Dell-B1160w-Mono ==Release Notes ===Version 0.0.1 Implementation of new, update, list and done commands. ===Version 0.0.4 * delete: deleting tasks or remove tasks from a task plan * plan: plan tasks and add them to the task plan * schedule: create a schedule with work and busy time and assign the tasks from the task plan to the free times ===Version 0.0.6 * start: start a task and track the lead time * stop: stop the tracking and print the lead time of the task * start, stop: the task is logged in the ~/.tasks/task.log file when added and when stopped * prio: prioritize tasks in the task plan, that is specifying the sequence in that the tasks should be conducted * plan: --move flag added to move tasks from the specified plan to another days task plan * update, new: when a follow-up or a due date is provided the task is added to the provided dates task plan. If both dates are set the task is added to both dates task plans ===Version 0.0.7 * updated rdoc ===Version 0.1.15 * IDs are now unique independent of the task or project directory. After upgrading from a version 0.0.7 or older the user asked whether to re-index the tasks. It is adviced to tar the tasks before re-indexing with $ tar cvfz tasks.tar.gz .tasks other_task_directories * start will now show a timer in the upper right corner of the screen when started with the -t (--timer) flag. $ syctask start 10 -t In order to use the task timer ncurses has to be installed as the task timer uses tput from the ncurses library. * The schedule has a heading with the schedule's date and the working time * Planned tasks are now added at or after the current time if they are not done yet. Done tasks are shown in the past with the actual processing time. Tasks done before the start of the schedule are not shown in the schedule. * Meetings that are at the current time are indicated with a *. Active tasks are indicated with a star, re-scheduled tasks are indicated with a ~. * Assigning tasks to meetings in a schedule is now done with the task ID * Statistics show statistics about work time, meeting times, general purpose tasks and task processing. Total, min, max and average time and count is listed. If you have used version 0.0.7 it is adviced to delete tasks.log that lives in ~/.tasks before upgrading or in ~/.syc/syctask after upgrading. Otherwise the statistic results seem odd. * Meeting time in time line now shows correct duration * Info command searches for the location of a task and lists all task task directories with the tasks contained. * Plan move command sets the duration to the remaining processing time but at least to 15 minutes * With the setting command the default task directory can be set and general purpose tasks can be created. A general purpose task can be used for tracking to analyse how much time for phone calls is occupied. setting -l list all general purpose tasks and the default task directory * Prio command now takes a position flag together with the order flag to determine where to insert the newly ordered tasks * All commands that take an ID as argument (done, edit, start, update) look up the task file associated to the id in the ids file. If it is found the provided task directory is not considered for the task file. If the id is not contained in the ids file the task is looked up in the provided directory * Inspect command allows to list each today's unplanned task to edit, delete, mark as done or plan * Update command now has a duration flag to set the task's duration ====Version 0.2.0 * Migrated from TestUnit to Minitest * Implemented _timeleap_ {<img src="https://badge.fury.io/rb/timeleap.svg" alt="Gem Version" />}[http://badge.fury.io/rb/timeleap] which allows to specify additional time distances to yesterday, today tomorrow. Time distances come in two flavors as long and short forms. Examples for long forms are - yesterday|today|tomorrow - next|previous_monday|tuesday|...|sunday - monday|tuesday|...|sunday_in|back_1_week|month|year - in|back_10_days|weeks|months|years Examples for short forms are - y|tod|tom - n|pmo|tu|..|su - mo|tu|...|sui|b1w|m|y - i|b10d|w|m|y ====Version 0.2.1 * Fix a bug in `syctask delete --plan` * Add indicator '>' to task list when task contains notes * Refactor migration from version 0.0.7 and when user has deleted system files. The user can now specify the directories where the tasks are located and can also define directories to be excluded. This is especially helpful to omit search in large mounted directories, like from NAS servers. ====Version 0.3.1 * Add csv output spearated by ';' to the list command * Fix bug when schedule file is empty * Add scan command to scan tasks from files ====Version 0.3.2 * Fix bugs of missing class lib/syctask/scanner.rb ====Version 0.4.2 * delete command can take now ranges of ids, e.g. 1,2,4-8,5,20-25 * inspect can now go back in the task list * inspect will now show the updated task after making changes to the task in edit * inspect allows to specify a follow_up date * scan will ignore columns that are not part of a syctask task * scan recognizes 'Follow-up' as well as 'follow_up' now. That is an underscore can be replaced with '-' * Fix bug when scanning tables that have spaces between separator and column * When tasks.log file is missing `syctask inspect` prints warning with reason why statistics cannot be printed ==Development Pull from Github and then run $ bundle install New classes have to be added to 'lib/syctask.rb' Debugging the interface can be done with GLI_DEBUG: $ bundle exec env GLI_DEBUG=true bin/syctask Building and pushing the gemfile to Rubygems $ gem build syctask.gemspec $ gem push syc-task-0.2.1.gem ==Tests The test files live in the folder test and start with test_.

WordSearcher generates a new word search puzzle with your input word, then tries to solve the puzzle. It is not programmed to win every game. It simply compares each letter of the word with all those available on the board, then randomly selects one. Then, it looks to see if the next letter of the word is joining the prior, and so forth. It plays more like a human, rather than a computer, so make the game more fun. Each time you play, notice that the board changes each time, even for the same input word.

Reads a text file (if supplied as the first argument) and creates a pdf file with the same name but with .pdf as extension in the current directory via the program pdflatex (the only requirement besides ruby itself). If '-h' is the first argument, then the program displays the helptext and exits. The program can also read the input text from STDIN (STanDard IN) and create the pdf file in the user's home directory. When this method is used, no argument is given to the program and the text is simply piped directly into the program like this: $ echo 'Hello' | txt2pdf This would create a pdf file with only 'Hello' and the page number at the bottom of the resulting pdf page. With this, you could map a key binding in your window manager to create a pdf file from the text you selected in any program, be it the terminal, your browser or your text editor. In my wm of choice, i3, I have added the following to my i3 config: bindsym $mod+p exec xclip -o | txt2pdf This would create a pdf file from the text I have selected as I hit the 'Window Button' and 'p'.

Formikation is a simple jQuery plugin to beautify form inputs, select, radios and checkboxes with some css. It supports custom theming and is IE8+ compatible.

Version 1.0.1 Update Notes: -Updated README "HOW TO RUN" -I'm not sure how to format this so it looks good on the gems website so please just see the README file. USE CASES: 1. Your friends bully you because your imaginary role playing worlds are predictable and boring. 2. You like seeing chars printed in nifty patterns. HOW TO RUN: 1. Run `super_simple_world_builder` 2. Follow the prompts EXAMPLE INPUT: Guten Tag! Welcome to Super Simple World Builder. Enter 1 to build a random world Enter 2 to build a custom world Please enter your selection (1, 2, or exit): 2 Enter the name of your world: Community-Town Enter the minimum width of the world: 15 Enter the minimum height of the world: 15 What character do you want to fill the background of your world with? (i.e. any character or single space) How many lake features do you want? 3 How many mountain features do you want? 2 How many town features do you want? 3 How many forest features do you want? 4 OUTPUT: 1. Console print out of the world map 2. A text file of the world map ACHTUNG: 1. Don't worry if the width or height entered is too small. The world will automatically enlarge to fit all features. 2. World maps look better when you enter a <space> as the character to fill the background. 3. This is a quick-and-dirty project so yolo with the specs. I added comments as a consolation prize. 4. See `feature_set.rb` to tweak the features that can be added to the world map. 5. Interestingly, menu prompts may not show up in the git bash terminal. But they do show up in Windows command prompt, so lmao. 6. Feel free to tweak the code however you like. I plan to refactor in the future to dry up some sections.
