In WinRT, is there a way to get information about the battery? I.e. similar information that shows in the desktop notification area: time remaining, percent left, percent left, etc.
There is no API available in WinRT - I've been investigating this about a month ago.
As Robin Yang mentioned on MSDN discussion:
GetSystemPowerStatus API is used to retrieve the power status of the
system. The status indicates whether the system is running on AC or DC
power, whether the battery is currently charging, and how much battery
life remains.
It seemingly can meet your needs. However, this API applies to
"desktop app only".
Its a pity you cant access such info, maybe writing status to local storage in scheduled task is the only option currently :-(
I don't think it a very user friendly way to do it, even it your could get through the store certification.
FOR /f %i IN ('whoami') DO set userId=%i
FOR /f %i IN ('dir /s/b %localappdata%\packages\\localcache ^| find "MyBatteryApp"') DO set appFolder=%i
echo Return = WScript.CreateObject("WScript.Shell").Run("cmd /c ""WMIC PATH Win32_Battery Get EstimatedChargeRemaining > %appFolder%\MyBatteryApp.txt""", 0, true) > %appFolder%\battery.vbs
echo ^<?xml version="1.0" encoding="UTF-16"?^>^<Task version="1.2" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task"^>^<Triggers^>^<TimeTrigger^>^<Repetition^>^<Interval^>PT15M^</Interval^>^<StopAtDurationEnd^>false^</StopAtDurationEnd^>^</Repetition^>^<StartBoundary^>2014-01-01T00:00:00^</StartBoundary^>^</TimeTrigger^>^<SessionStateChangeTrigger^>^<StateChange^>SessionUnlock^</StateChange^>^<UserId^>%userId%^</UserId^>^</SessionStateChangeTrigger^>^</Triggers^>^<Settings^>^<DisallowStartIfOnBatteries^>false^</DisallowStartIfOnBatteries^>^</Settings^>^<Actions^>^<Exec^>^<Command^>wscript^</Command^>^<Arguments^> //B //nologo %appFolder%\battery.vbs^</Arguments^>^</Exec^>^</Actions^>^</Task^> > %tmp%\batterySetting.xml

I am still new in Octave with some experience in Python and I was requested to do a test in a stimulus application in order to find if there are errors in the code (not developed by me) and try to fix them and run the application. The issue in the code is at the time to open the screen as follows the implementation (these ones where I commented (%) are what already did before, and these ones below the comments are my correction) the code is large with 825 lines:
%% Get subject name from the user
prompt = {'Enter Subject Number:','Enter Subject Name:','Enter Todays Date:','Left or Right:'};
dlgtitle = 'Information Input';
%dims = [1 50];
dims = [1 50;1 50;1 50;1 50];
opts = 'on';
answer = inputdlg(prompt,dlgtitle,dims);
%waitfor(answer);
waitfor(dims);
%% TO Excel
% Get the name of the file that the user wants to save.
%startingFolder = userpath;
startingFolder = 'C:\Users\Vtr\Downloads\Final-task-981203\Final-task-981203\Task-981203';
defaultFileName = fullfile(startingFolder, '*.xlsx');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a filename ');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
% Combine the folder and base file name into the full file name.
fullFileName = fullfile(folder, baseFileName);
%% LOAD text initial setting
%% Create 1st screen : (Loading and Wait)text screen
% Open an on screen window - purple screen
[window, windowRect] = PsychImaging('OpenWindow', screenNumber, [0.5 0.5 1]);
% Set up alpha-blending for smooth (anti-aliased) lines
Screen('BlendFunction', window, 'GL_SRC_ALPHA', 'GL_ONE_MINUS_SRC_ALPHA');
After that, in the first part is created a form to insert subject nº, subject name, today's date and left or right, and after that to specify a filename. Made these two parts it appears a purple screen with the mouse's cursor rotating non-stop and if I try to click with the mouse an error alert box "octave-gui.exe has stopped working" appears on. I already tried to run this code on my Virtualbox-VM (Ubuntu 16.04 LTS), firstly, it notifies that my screen is being tested and calibrated and after, it appears another error screen on the terminal:

I would like to know if the issue is in my computer configurations that don't support Psychtoolbox resources or any configuration that I need to change.
I have an AMPL script that involves calling "solve" on a linear program many times. The solver I'm using is MINOS. After every time it solves, it outputs:
MINOS 5.51:
"option abs_boundtol 2.220446049250313e-16;" or "option
rel_boundtol 2.220446049250313e-16;" will change deduced dual values.
Is there a way to suppress this message?
I read this in the MINOS instructions:
For invocations from AMPL's solve command or of the form
minos stub ...
(where stub.nl is from AMPL's -ob or -og output options), you can use
outlev= to control the amount and kind of output:
outlev=0 no chatter on stdout
outlev=1 only report options on stdout
outlev=2 summary file on stdout
outlev=3 log file on stdout, no solution
outlev=4 log file, including solution, on stdout
which might be relevant but I don't understand it.
I have included "option solver_msg 0;" in my script; it turns off the announcement from MINOS that it got such-and-such an optimal value with so many iterations, but it doesn't affect the message I'm asking about here.
You can redirect the remaining solver output to /dev/null (or equivalent for your system) as follows:
solve > /dev/null;
As for the message about abs_boundtol and rel_boundtol, I think you can set them to a small positive value larger than 2.220446049250313e-16 to make the message go away. Note that this will affect the dual values computed for presolved constraints.
See also https://groups.google.com/d/msg/ampl/ERJ8nF_LnNU/75yWK9deBjUJ
for me "option show_boundtol 0;" worked. You can try this. By default it is "option show_boundtol 1;".
You can read about it here (http://ftp.icm.edu.pl/packages/netlib/ampl/changes)
In the opening page of the book of "Lisp In Small Pieces", there is a paragraph goes like this:
Based on the idea of "function", an idea that has matured over
several centuries of mathematical research, applicative languages are
omnipresent in computing; they appear in various forms, such as the
composition of Un*x byte streams, the extension language for the Emacs
editor, as well as other scripting languages.
Can anyone elaborate a bit on "the composition of unix byte streams"? What does it mean? and how it is related to applicative/functional programming?
Thanks,

My guess is that this is a reference to something like a pipe under linux.
cal | wc
the symbol | it's what invokes a pipe between 2 applications, a pipe is a feature provided by the kernel so you can use pipes where the applications are written using this kind of kernel APIs.
In this example cal is just the utility that prints a calendar, wc is an utility that counts words, rows and columns in the input that you pass to it, in this case the input is the result of piping cal to wc which makes things easier for you because it's more functional, you only care about what each applications does, you don't care, for example, about what is the name of the argument or where to allocate a temporary file to store the input/output in between.
Without the pipes you should do something like
cal > temp.txt
wc temp.txt
rm temp.xt
to obtain pretty much the same information. Also this second solution could possibly generate problems, for example what if temp.txt already exists ? Following what kind of rationale you will tell to your script to pick a name for your temporary file ? What if another process modifies your file in between the 2 calls to cal and wc ?
it seems that it is not possible for me to trigger an event in OpenNMS using a threshold...
first the fact (as much detail as i can)
i want to monitor a html file, better, the content.
if a value is not what i expected OpenNMS should call be.
my html file:
Document Count: 5
in /var/lib/opennms/rrd/snmp/NODE are two files named: "documentCount" (.jbr & .meta)
--> because of the http-datacollection-config.xml
in my logfiles is written:
INFO [LegacyScheduler-Thread-2-of-50] RrdUtils: updateRRD: updating RRD file /var/lib/opennms/rrd/snmp/21/documentCount.jrb with values '1385031023:5'"
so the "5" is collected correctly.
now i created a threshold for this case:
<threshold type="high" ds-type="node"
value="4.0" rearm="2.0" trigger="1" triggeredUEI="uei.opennms.org/threshold/highThresholdExceeded"
filterOperator="or" ds-name="documentCount"
/>
in my collectd-configuration.xml is the threshold also enabled:
in my opinion the threshold of 4 is exceeded, because the value is 5. so the highTresholdEvent should be fired. BUT IT DOESNT.
so i'm here to ask if someone had an idea.
regards dawn
Check collectd.log with the following
tail -f collectd.log | grep -i thresholding
Threshold checking was moved to evaluate while the data is being retrieved a while back as opposed to a post process of rrd files.
Even with the log setting at info you should find some clues as to why the threshold rule is not matching any data.
I'm attempting to automate something at work that requires minimal background process. Normally I'd use C#, but this is problematic, as part of what I'm automating is a test process that scans the system looking for running processes. Command windows are fine, but most anything beyond that get's to be problematic.
As part of kicking off this series of tests, I am trying to find a way to get a batch file to read one line at a time from a .csv file. Each line contains 4 values (separated by commas, of course) which should be put into variables. The first var will be the test number. When starting the batch file, I'll be providing a test number as an arg, and want it to compare the test number received to the test number it read from the file. If it matches, continue testing. If not, move on to the next line and read that data into the variables.
Everything else is really simple, but I can't figure out how to get it to read and parse a .csv file one line at a time in the manner described. Any help would be appreciated.
Just for information, I am well aware of how to do this in C#, and I know there are many other solutions that would be better (easier) than batch files. However, there are specific reasons why employing those solutions is a poor idea in our situation, so we're trying to go old school with the batch files.
#echo off
rem Read theFile.csv and get 4 tokens separated by commas
for /F "tokens=1-4 delims=," %%a in (theFile.csv) do (
rem Tokens read are placed in %%a, %%b, %%c and %%d replaceable parameters
rem If first token is equal to first Batch file argument
if %%a equ %1 (
rem Continue testing here, ie
echo %%a,%%b,%%c,%%d
)
)
