I need to reuse a function in a file. The usual way is just to import this file as a module. But what to do if the name is “bad”? The following doesn’t work:
import foo-bar as foo_bar
foo_bar.callme()
After trials and errors, the desired magic found:
Yes, one installs and configures Samba. All I need is to access a big folder in the read-only mode. The quick and dirty solution is:
Consider ‘main.bat‘
call child1.bat
call child2.bat
What happens after ‘child1.bat‘ is finished?
Extending a virtual disk in vmware
1. Backup!
2. Somewhere in the vmware installation directory, there is a tool named “vmware-vdiskmanager.exe“. There is a lot of options, for resize use “-x“:
vmware-vdiskmanager.exe -x 8Gb ...path.to.vm..../vm_disk.vmdk(hint: type the command manually, do not copy/paste from web. Otherwise you can get typographical spaces or minuses instead of the usual ones.)
After a small system upgrade an application started to crash with the message:
*** glibc detected *** sylpheed: double free or corruption (out): 0x0839e818 ***
The right thing is to trace the application and submit a bug report to the author, but I found a fast workaround. Set an environment variable before running the program:
export MALLOC_CHECK_=0
Upgrading a macports (darwinports) package is not as easy as
$ sudo port upgrade something
In many cases I need the following command:
In addition to the conference checklist, I now need a checklist for local chess tournaments.
For development purposes, I’d like to run a rsync server on a Mac.
People in forums recommend to avoid the default system rsync, which is accused of being buggy. Instead, they recommend RSyncX.
It’s quite easy to create a local MacPorts repository. Unfortunately, the documentation doesn’t say how to share the repository with others. After trials, errors and reading the source code, I’ve found the answer: the only way is rsync.
I’ve noticed that headers and footers of the documents, generated by XeLaTeX, use some other font instead of Helvetica. After digging into the LaTeX code, the problem is solved.
Do you generate [La]TeX files using Python? If yes, do you escape the special characters. Haven’t you forgotten to escape also empty strings?
To avoid reinventing the wheel, I tried to use TeXML libraries. This is the right choice, but one has to use a little trick.
ALSA is the Advanced Linux Sound Architecture. The system can forward ALSA sound to PulseAudio.
PulseAudio is a sound server. Applications feed music to PulseAudio, and PulseAudio decides what to do with it. For example, it can send the sound over network.
When I tried to use this feature for the first time, I failed. Therefore, I experimented with a more user friendly software (see multimedia over network I, and the second attempt was successful.
I need to get utf-8 (unicode) data instead of 8-bit from a Microsoft Access database (ODBC connection). It seems I’ve finally found the answer:
It’s impossible.
I wanted to convert text to curves in PostScript. The well-known tool to do it is pstoedit (alternatives are welcome). Unfortunately, it worked only partially.
I want to:
* run a program on a work PC, and
* see and hear it in action on a leisure PC.
The first attempt is failed, therefore I started to search for a solution using the step-by-step approach. The first step is to make sure that multimedia over networks works at all.
I always used vim (for example, “Ctrl-K” “:” “u” for “ΓΌ”), but now I found a way to input such characters into any application, using the core feature of X11/xorg. The explanation and the table are here: “ISO-8859-1 compose keystrokes in Linux” (thanks Andrew Daviel).
Reminder for myself: on my system, it’s enough to add “compose:ralt” to the option “XkbOptions” in “xorg.conf” and use “Alt Gr” key.
After upgrading my Linux, I’ve got sound lost. Everything looked ok — all the modules are loaded, all the special devices are created, no complaints in logs, — but no sound.
There is a number of XML-editors, but there are no user-friendly ones (except FraemMaker). A standard XML editor is a tool for programmers, to play with XML. But technical writers need an user-centric XML editor, to play with a document, not with XML.
I’ve impressed by the site Exeter Chess Club, and especially Coaching page. A lot of useful resources.
