Many applications and servers create log files that record events. Log analyzers are being used to analyze the log files more comfortably. It’s theoretically possible to use a text editor to analzyze log files or a desktop search tool that indexes contents but log anyalyzers usually provide access to features that these general tools do not offer.

Log Lady might be a strange name for a log analyzer. The portable software program does offer an interesting feature that many other log analyzers do not offer. It can load multiple log files in its interface to search them simultaneously.

Only two steps are needed to perform a log analysis of multiple log files. A directory on the local computer system has to be selected. The software program will automatically display log, txt and xml files and filter the rest. It is possible to display all files that reside in the folder which can be useful if the log files have a different file extension. All or only some of the log files can then be selected for analysis.

The log analyzer will recognize the columns of the log file and offer to search in all columns or a specific one.

The results of the search are then displayed in the central area of the program. It is furthermore possible to export the results of the log analysis in a csv file.

Log Lady is a free software program for the Windows operating system. The log analyzer can be downloaded form the developer’s homepage.

LicenseCrawler is a portable and free tool for retrieving serial numbers and product keys from your computer. A simple scan with LicenseCrawler ensures you’ll never be left trying to reinstall software without the proper key.

It found a number of licenses on our test system, but it if the application in question doesn’t store its product key in the registry—instead in the program or application data folder—LicenseCrawler will miss it.

Window/Linux: Fixing a tag here and there is one thing, but what if your MP3 collection is in need of a deep and serious massaging to get things in order? MP3 Diags lets you dig into the guts of MP3s.

The creator of MP3 Diags was frustrated with how limited many of the MP3 repair tools he used were and how many of them used tags incorrectly or inserted their own tags into the MP3s. MP3 Diags is a powerful MP3 editor that not only allows you to diagnose and fix surface problems with your MP3 collection such as incorrect track numbers or song names, but it digs even deeper and enables you to repair things like problems with the VBR header and other hidden but important aspects of your music collection.
