Does anyone have the name of a good program that will allow me to create text files with mathematical notations and symbols? I like to ptake notes at school on my laptop but I find it difficult to do so in my math classes. I just downloaded a program called Mirai Math. Haven't tried it yet but it looks a little to clunky. I'm looking for something simple.
View 7 RepliesI've been wondering about this for a long time but never thought to ask: I do a lot of scientific work so there are many times it would be really handy to be able to type mathematical symbols or Greek letters which, for the most part, aren't part of the ASCII character set. Like "∞ ρ σ τ ω ∑ ... √ ∫ ≤ ≥ " and so on. Is there a keyboard layout (for Linux) that maps simple key combinations to these kinds of characters? (Assuming all the encoding and font issues are worked out properly) I know I could create one myself but it'd be a lot easier if someone's already done the work, or at least if there's a partial solution I could modify.

Aborted (core dumped) I'm following the Fedora Bible (2010 edition) and I'm trying to get KDE up. This is what it says to do: After running switchdesk or switchdesk-gui, you need to perform one other task. As root, edit or create the file /etc/sysconfig/desktop. Add the following lines to the file:
DESKTOP="KDE"
DISPLAYMANAGER="KDE"
However, I receive that error. Does it want me to log in as root? I tried and it wouldn't let me, so I tried looking up how to do it, and I needed to change another text file with su (which is my problem in the first place). Just to be clear, this error occurs in any directory that I'm in. (home, or otherwise)
When I try to open text file with mouse pad or kate write all I see is PK and in small letters HF over TF_. I have no idea how this happened. How do I get my text document back? Using XFCE4.6.1, mousepad and kate write for my journal. Properties says its a zip archive but I didn't do that. Anyway tried to unzip it and got:
Code:
PowerJustice may be a plain executable, not an archive
unzip: cannot find zipfile directory in one of PowerJustice or
PowerJustice.zip, and cannot find PowerJustice.ZIP, period.
Can anyone point me to a well working peace of software (free will be preferred) that can convert text-files into pdf.

I have 2 text files : file1.txt and file2.txt
cat file1.txt
15 this is a sentence containing various words and spaces
34 this is a another sentence containing various words and spaces
cat file2.txt
2 this is sentence1file2
6 this is sentence2file2
54 this is sentence3file2
I would like to join these 2 files. The result should look as follows :
cat joinedfile.txt
2 this is sentence1file2
6 this is sentence2file2
15 this is a sentence containing various words and spaces
34 this is a another sentence containing various words and spaces
54 this is sentence3file2
==> so the joined file must be sorted on the first number. Any ideas how this can be achieved ?
I am using Centos 5.4 with gcc v4.1.2. If I take a bunch of .o files and I then link with my main.o to form an executable then this links and executes just fine. If however, I try to create an archive file (.a) using 'ar rus xxx.o yyy.o etc' and then try to link the resulting .a with my main.o then I get 'undefined symbol' linker errors and I don't understand why.

View 1 Replies View Relatedmay be an advanced question but I need to know how to do this. Here at work I am in charge of recruiting and we have about 1,000 resumes in already. All of the resumes are in a .pdf format. I need to rename every .pdf in the following format:{firstnameLastname}.pdfThe only way I know how to do this is to convert all the .pdf files to text, extract the name out of the first few lines of text, import into excel, and then use VBA to rename the files in mass:Here is my logic so far:~Deskop/a = houses all the .pdfresumesOpen terminal: Code: cd ~/Desktop/afor f in *.pdf; do pdftotext -raw $f; done That will convert all of the preceding resumes into text filesNow I would like to append the name of the text file into the last line of the text file. So, for example, for Resume1.txt, I want to append "Resume1.txt" to the last line within Resume1.txt. So after I run the command I open Resume1.txt and on the last line within I want to see "Resume1.txt" on the last line, at the end of the resume.How can I do this? I would like to use a loop and have the terminal append the filename to the body of the text file until all of the have been appended.
