Getting Eclipse CDT to spell check non-source files

  1. Problem:
    1. Using Eclipse Luna CDT, with C/C++ spelling engine, to document C and C++ code in Doxygen (Eclox plugin), image
    2. Spell check works for inline Doxygen documentation. My API-level code comments in *.[ch](pp)* files gets spell-checked alright (Well…:
      1. I had  to download a decent dictionary to avoid recommendation like this one: image. I am using the aspell dictionaries from here and here.  This is before a restart/recheck:image
      2. I still do not know how to teach the C++ spell check engine that a newline does not start a new sentence: image
      3. The oft-referred to menu: Edit / Spell check does not show up for me: image
    3. However, spell check ignores my standalone *.dox files with high-level documentation.
  2. What I have tried:
    1. Telling Eclipse about the*.dox file type: image
    2. Associating *.dox files with the Doxyfile editor: image. Fail. This tool from the Eclox plugin seems to help only with the editing of the Doxygen config file. image
    3. Associating *.dox files with C/C++-editor: image Fail: has no effect.
  3. Workaround:
    1. Terrible, but since a similar question is still open on stackoverflow): If you can (*.dox requires all comments to be within c-style comments anyway), rename your *.dox files to *.dox.cpp. Terrible, but works: image
    2. A bit less terrible if you mange to store your standalone *.dox files as *.dox.cpp permanently do this if you get your Doxygen to handle these extensions.
    3. What is nice to see is that the spell-checker  recognizes Doxygen’s built-in reserved words (as opposed to my custom-defined Doxygen-commands). image
  4. Other things to try:
    1. I could not get Hunspell4Eclipse to work, despite going to considerable trouble getting the marketplace into my Eclipse installation
    2. I have not tried eSpell.

Web browser popup blocker exceptions need configuring


  1. Which computers
    1. This I found on the Reception desk
    2. but isn’t that then also wrong on all student pcs which have the same base image?
  2. Which exceptions missing: I noticed immediately:
    2. should read
  3. Which browsers
    1. Example is IE9,
    2. But are others different?

Manage some of your teacher computer settings per logged in user

  1. Another day, another hack, and inconsequential, unless of course you are in my situation:
  2. If you need a simple way to change some of your Sanako settings per logged in user
  3. but cannot use the logged-in user system built into Sanako Study 1200:


$path = "C:\ProgramData\Sanako\Study\Tutor\"

; change the sanako default save to dual track supporting mff
	; prereq: customized settings files in the folder ready to rename 
	FileCopy($path & "mffTutor.Settings", $path & "Tutor.Settings", 1)
ElseIf (@UserName = "tplagwit") Then 
; change the sanako default save to dual track supporting wma, for testing
	FileCopy($path & "wmaTutor.Settings", $path & "Tutor.Settings", 1)
; keep the default mp3, but we may have to reset the tutorsettings on this unfrozen computer
	FileCopy($path & "mp3Tutor.Settings", $path & "Tutor.Settings", 1)
; tutor.exe could be hardcoded to (re)load here
If ProcessExists("Tutor.exe") Then
	; determine: we could kill tutor to reload it, but that could be disruptive of a class
	Run("C:\Program Files (x86)\SANAKO\Study\Tutor\Tutor.exe")

Trying to reduce Attempt abandoned in Hot Potato Hot Pot Moodle quizzes

    1. The Hot Potatoes quiz activity per se does not seem to have a submit button, since it is auto-grading, per question.
    2. . When the quiz is completed, the string in ExerciseCompleted (usually: “You have complete the exercise” )appears in a modal dialogue and on top.
    3. image
    4. Before Exercise is complete, the instructions now remain, since I have turned off ShowCompleteSoFarclip_image001
    5. One could make  ExerciseCompleted much more visible (like with ShowCompleteSoFar permanently in a Hot Potatoe inhstallation), if looking out for this message would help the students not abandoning the quiz early: image

Sanakoaudioconfigonthefly software utilities updated for Vista/Windows7

  1. (Shortcut to download – now fixed) The reason why a colleague’s signature reads: “Worrying about a large institution, especially when it has computers, is like worrying about a large gorilla, especially when it’s on fire" (Bruce Sterling) might just be that a multimedia-capable fully computerized classroom – think 30 PCs and 30 students trying not only to listen to, but record responses to exam audio – is a notoriously difficult beast to control, and all too easily spins out of the same (a classroom humming in an endless audio feedback loop is neither a pleasant nor an unfamiliar sight).
  2. The Sanako Study 1200 is a digital audio lab software that facilitates the use of personal computers in face-to-face class settings. However, while the Sanako Study 1200 features many ways for the teacher to control and manage the student PCs, the students’ audio settings cannot be controlled on the fly.
  3. Enter these little sanakoaudioconfigonthefly utilities (written in AutoIt) for Windows 7 and Vista  (old Windows PX version still available here) that extend the Sanako Study 1200.
  4. We now use  (as it is completely adequate and actually superior to to the seemingly more applicable PC control / Launch programs features which is requires the program executable to reside under the same path on student and tutor computer) Playlist / copy and launch (folder icon) and the Sanako grouping feature to send a program with your choice of action to the student PCs  of your choice. In this example,
    1. click playlist, 01
    2. and in the window that opens, click (1) to send to “all”, then click (2) to select which program to send: image_thumb[3]
  5. Files included in this release (each for 64-bit, and as source code, so that you can compile your own if you are still on MS-Vista/MS-Windows-732-bit platform):
    1. Change student recording levels (microphone sensitivity).
    2. Toggle student sidetone ( in Sanako = “listen” to this device in Windows)
    3. Control student playback level (headphone volume).
  6. Likely these programs can be adapted beyond Sanako Study 1200, but I do not remember (helpful comments appreciated)
    1. whether other digital audio lab platforms (Sony Virtuoso, Robotel SmartClass) allow for changing the student audio config on the fly
    2. and what mechanism (if any – but likely) they (and Sanako Lab300) provide to launch programs on the students’ computers
  7. Prerequisites:
    1. None other than your digital audio lab software and the utilities you can download below. In particular, it is not required to install AutoIt on teacher or student computers.
    2. However, there should be only 1 microphone/speaker per student computer in the digital audio lab. If you have more, you likely have bigger problems to solve first, but you also need to alter the source code (included) to select the microphone you want to work with (should be easy; note however, that I have not tested this scenario, for: “There should be only 1 microphone/speaker per student computer in the digital audio lab” Smile

    Testing and semi-automatically changing the Sanako student audio configuration

    1. Problem
      1. We have had teacher complaints about too much background noise from neighboring students being recorded in our Sanako Study 1200, with SLH-07 headsets.
      2. In addition, upon looking through some recordings as samples for a workshop, I found cases of clipping audio, especially in pair recordings.
      3. We are using the default settings for the Sanako SLH-07 headset. However, the default recording level (67) seems high.
    2. Solution approach
      1. We need to test
        1. many other settings quickly for these recording levels. We use my sanakoaudioconfigonthefly utility for this
        2. in an acoustically realistic environment: 5 Lab assistants  site in tight lab area and read out sample English text during a Sanako reading activity
          1. Reading practice
          2. Todo: Pairing
      2. Here is a “window” into the recorded results set, a student’s audio recording shown in Audacity at various (but all lowered) recording levels from (visible) 30 to 5, you can see the diminishing waveform amplitude. image
      1. The waveform per se is not conclusive. You will have to listen in and compare, especially to evaluate background noise (the original complaint – we have no and will not be able to go back to language lab carrels). The Sanako SLH-07 headset microphones are supposed to be highly directional. However, our students to not always wear the headsets properly. And our acoustics is marred by large (almost 50%) window spaces and a tight positioning of the student seats.
      2. Any test recording is only as good as it can mimic the acoustics during an actual class session which we did as much as we could with only 6 concurrent LRC staff. This means  unfortunately some more testing will have to spill into actual classes, but this test is a start.
