uGet’s browser integration module does not seem to support content-disposition fields. This often results in downloaded files having inconvenient names like download.php or some GUID like e94d8f80-7e18-11e9-80e1-46db6c91c5c0. This problem did not exist in older versions of uGet since it used to auto-rename files ignoring file names set by users or by plugins. This behavior has now changed. Solution uGet uses either aria2 or cURL as a backend to download files. Both programs support getting the filename from the content-disposition header.

If we improve only one aspect of a computer system, the overall improvement in performance is limited by the extent the improved aspect is used. Amdahl’s Law addresses this limitation. The law was presented by Gene Amdahl in 1967. Amdahl’s paper focuses on the potential speedup that can be expected by using multiple processors. The law can be generalized to assess other areas of performance as well. For example, we can asses improvements in floating point performance, memory, etc.
