If you put an Android Studio project under version control with Subversion, you will have to exclude some files from version control. Otherwise you will have local settings in your repository which will not work on other workstations. See what you have to add to Subversion’s ignore list.
If you try to access an environment variable via Jython’s
wsadmin of WebSphere AS and you are on the “wrong” Windows release you will get an
IOException telling you “Cannot run program “sh”: CreateProcess error=2, The system cannot find the file specified.”. On a Unix or Linux system running the same script in
wsadmin you won’t have any problems. A strange situation caused by Jython, not by WebSphere itself. — Here you will see why and you will find a solution.
When I tried to load an exported ICS file into Baikal’s calendar I encountered fatal problems. Most of the appointments could not be loaded. A similar problem occurred in conjunction with ownCloud’s calendar. The uploaded ICS file did not follow the icalendar/vcard format, ownCloud reported in its log. I found out that the problematic events in the ICS file were containing properties brought in by invitations generated by Lotus Notes. The reason why Baikal and ownClound could not deal with them was finally found easily. Both products, ownCloud and Baikal, are using SabreDAV for implementing their CalDAV functionality. SabreDAV applies strictly the iCalendar specification (RFC 2445) while parsing ICS files. Unfortunately extensions by Notes or Outlook might be problematic. This default behavior of “strict applying of the specification” can be changed. A simple change of a default parameter setting worked fine for me in Baikal as well as in ownCloud. Continue reading
On my Windows PC my primary tool for accessing subversion repositories is TortoiseSVN. A while ago I updated to TortoiseSVN 1.8.4. This version of TortoiseSVN is based upon Subversion 1.8. So I migrated all my working copies from SVN 1.7 to 1.8. So far, so good.
Unfortunately later I realized that SvnKit in NetBeans 7.4 is still based on Subversion 1.7 and no update to 1.8 is available by now. So SvnKit started telling me “sorry, SvnKit is too old to work together with your SVN working copy”. No problem, I thought. I switched to command line tools (CLI) as mentioned by SvnKit. All went good, except for repositories via HTTPS using SSL/TLS certificates signed by an internal root-CA and self-signed certificates respectively. Continue reading
With this blog post I release an object-oriented PHP implementation of the RSA public key algorithm. The implementation is based on Edsko de Vries’ non-object-oriented implementation. Additionally to the object-orientation I reimplemented the signature methods which are now based on encrypted hashes instead of encrypting the whole message. This post shows you how to use this cryptographic PHP module, called rsa4php, and where to download it. Feel free to use it in your own programs under the terms of the GNU General Public Licence (GPL). Continue reading
On Unix it is easy to get your numeric UID and the GIDs of your primary group and secondary groups. You call the program
id simply. On OpenVMS it is not such easy to retrieve your numeric UIC which is OpenVMS’s equivalent to Unix’ UID and GID. With a bit DCL magic you can write a command procedure which tells you the UIC as easy as
id tells you your UID and GID on Unix. By programming this little command procedure you will also get introduced to lexical functions in DCL. Continue reading
