I hope you can solve this or at least tell what to do about it because I'm clueless. The thing is that once I've saved a .wxm file and then want to open it appears on wxMaxima this error and the "app" crashes:
Maxima encountered a Lisp error:
decoding error on stream
<SB-SYS:FD-STREAM for "socket 127.0.0.1:62607, peer: 127.0.0.1:4011"
{13F30991}
(:EXTERNAL-FORMAT :ASCII):
the octet sequence (195) cannot be decoded.
Automatically continuing.
To enable the Lisp debugger set debugger-hook to nil.
Thanks in advance.
P.S.: I run the latest Mac OS X version on my iMac.
Create a new file and write it down.
(setf sb-impl::*default-external-format* :utf-8)
(setf sb-alien::*default-c-string-external-format* :utf-8)
Save the file as .sbclrc at Home (User) folder.
I come back on this post as I have been affected by this today.
I am using Ubunutu 14.04 and the same bug appears. To me it is due to Maxima not being able to load anything else than ".mac" files, nothing to do with utf-8/ASCII (I have mv a file that is working to a wxm and vice-versa, it will not work anymore / rework)
Also I have prepared a workaround:
The idea is too have a tool that translates your .wxm files to a .mac file just before you load it (it is actually a very easy bash script)
So:
you put the wxm-to-mac.sh files into your path
then inside maxima, instead of doing
load("foo.wxm")
you simply do
system("wxm-to-mac foo.wxm")$
load("foo.mac")$
Bare in mind you shall not edit the foo.mac file because a routine might re-erase it afterward. Instead keep editing the .wxm file.
Hope it helps someone
Looks like the file has been saved with some non-ASCII characters (e.g. UTF-8) in it, but it is not read as UTF-8; that seems to be a bug in wxMaxima. Can you please post the offending .wxm file?
I was having the same problem, since none here could give a straight and correct answer (at least is not marked with the green icon) i tried to look somewhere else. I couldn't find an answer that solve my problem, but then i thought that i had used WxMaxima on Mac before and it worked pretty nice. The last time i installed wxmaxima on mac and it worked was in september 2012, i went to the http://sourceforge.net website and searched for the maxima file that was available on that date and i found http://sourceforge.net/projects/maxima/files/Maxima-MacOS/5.18.1-MacOS/, i installed it and its working pretty fine (about the problem, it is weird, even if i create a new maxima file typed "a" and saved it, i could no longer open it, so i'm guessing that it has nothing to do with ascii or non-ascii characters) I have no idea why this error happens on the recent version of Maxima/WxMaxima, but it makes no sense that we have to install a previous version for it to work.
Anyway, it's working for me, and i hope it works for you too. Glad i helped :)
I had the same problem.
In my case, the name of the directory where the ".wxm" file is located, contained Korean letter. I changed the directory name with an English one.
Then the problem has been solved.
I hope this works for you, too.

I have a problem where I am creating an Android app using Firemonkey in Delphi XE6. The app consists of a TWebBrowser and a button...nothing fancy.
I am TRYING to display an xhtml file that is located on my SD card.
I "think" I am doing all the right things like using "TPath.GetHomePath" and putting my file in this location. - and made sure the permissions are set in the project.
Being a seasoned developer, I know that I need to use "file://" so the browser knows it a local file, as I have done a million times in Delphi over the years, and even checking the help file which uses the example "WebBrowser1.Navigate('file://MyFile.pdf')"
So I construct my URL by doing :
AppPath := TPath.Combine(TPath.GetHomePath, 'myfile.xhtml');
I then go:
WebBrowser1.Navigate('file://'+AppPath);
When the navigation happens, it tells me the file doesn't exist, file:///data/data/com.embarcadero.WebBrowser/files/myfile.xhtml
I spotted the 3 /'s i.e. file:/// and thought I would just hard coded the path into a string and got the same problem saying the file doesn't exists and it reverting back to file:///
Can anyone see what I am doing wrong? its got me puzzled thats for sure! :-)
Thanks, Jeremy
Instead of
TPath.GetHomePath
i used
TPath.GetPublicPath
which leads me to /storage/emulated/0/Android/data/<myapp>/files/ folder (the one i need).
TPath.GetHomePath
gives me data/data/<myapp>/files/ which is not exists (i guess, maybe i need something like GetAbsolutePath).
I know this isn't really code related, but I don't know where else to ask?
While working yesterday I got a message saying that my startup disk was almost full. Which I wasn't too surprised by because it's only a 128gb Air.
But when I fired up Daisydisk to see what the issue was it appears that my computer has stored 2 files in the private/var/tmp directory, each over 30gb. Obviously Daisydisk won't let me erase them because of the directory they are in.
They are called magick-23598T_US4im5XKvQ.pam and magick-23587vell8J7UTKgS.pam
I have no idea where they came from, but I was testing a file upload system for a rails project when this happened. I was however uploading images over no more than 800kb or so. This seems a little extreme for that.
If anyone has any idea what might have happened, or how I can safely free up this space again, I would be massively grateful.
Looks like ImageMagick temp files -- are you processing the images with ImageMagick? There's a similar problem discussed here although the exact cause may be different.
It is likely a large swap file from ImageMagick that hasn't been cleaned up. You can limit the file sizes by editing your policy.xml config for ImageMagic (/etc/ImageMagick/policy.xml on Ubuntu).

I'm working with a program, which I need to document and review, but which I did not write, nor did anyone I can easily reach. One of the problems I've run into is that it is supposed to read and work with .avi files, but every time I try, it fails. The file is an avi converted from an MTS format. The computer seems to think that it is an avi file, and it runs it without incident, but I don't know why the cvCaptureFromAVI is having trouble.
The function cvCaptureFromAVI simply returns null. I can't seem to get any deeper in the code to see what in cvCaptureFromAVI is causing the error, and I haven't been able to get any error information about why it won't read the file.
I was struggling with this problem for two days!
If you've double checked all other possible causes (file is in correct directory and inside your code the path to that file is in correct format) and still cvCaptureFromAVI returns null, the problem is your computer codecs.
I suggest you installing K-Lite Codec Pack. Remember to restart your computer if you are using Windows.
I am getting file list in my Java program using list() method of File class. When I run my program on Knoppix I get ???? instead of Cyrillic file names. It seems that problem is in knoppix, not java. I tried to use options for mounting file system, such as nls and iocharset, but it has no effect (or may be I use it in wrong way). Somebody can help me?
I think that problem is as you said with Knoppix. Probably you do not have Cyrillic font bundled, so there is no way to display these code points.
If you want to fix this, you will need fix distribution, as there is nothing wrong with the program. I am not sure if this is the question for https://serverfault.com/ or https://superuser.com/, but you can read their FAQ's and ask how to fix it there (probably you will need to re-create Knoppix distribution).
is there anybody out there, with experiences about how to do a gantt-diagram / chart using latex.
I tryed it for a lot of hours today, lastly it worked switching outpout from pdf to dvi.
Maybe someone can tell me what to include, besides pst-gantt, and the normal pstricks stuff.
It showed more than 100 errors for 4 Tasks.. after switching to dvi there was a big 0.
i am using the whole distribution mitex .. upgradet to the newest version. stupidly i have the error log not avaible on this computer. but it was always the same error. i was using pst-gantt, outload missing packages.. hm errors will follow tomorrow morning
Reading the pst-gantt README it looks like this depends on the pstricks package. I believe that the "ps" is for postscript and the functionality is implemented by generating DVI "special" commands; which means that you can't produce output pdf directly using pdflatex. You can get to PDF output, but you must go by way of DVI. Either source->DVI->PDF or even source->DVI->PS->PDF.
I came across this question when having trouble with pst-gantt and pdflatex. As others have pointed out you need to go via DVI, which honestly sucks if you have used pdflatex all the time.
So I did some search, and found this phantastic replacement written by Martin Krumm: http://www.martin-kumm.de/tex_gantt_package.php
