Our existing code signing certificate was due to expire this year, so it was time to renew. This time around we found the certificate authorities were advertising Extended Validation (EV) code signing certificates, which are a-kin to EV/OV SSL (TLS) certificates that result in the larger green bar on some web sites. Extended Validation means the […]

Many Windows software vendors will continue to feel the pain after learning the hard way that SHA1 deprecation occurred, or, as in our case, weren’t as ready for that as they thought! This is the story of our experience, where we had switched to dual-signing with SHA1 and SHA2, but didn’t get it precisely right […]

During the course of development of Process Lasso and other Bitsum software, it became apparent that we needed a way to express CPU affinities in an efficient, shorthand, textual manner. This specification became used by the Default CPU Affinities and, in fact, all CPU Affinity settings of Process Lasso. The specification is quite simple. It is […]

This minor update to ParkControl offers several language refreshes and corrects an error in the last version where the licensing information wasn’t as visible as it should have been. It also adds dual-signing with SHA1 and SHA2, as will be the case of all Bitsum binaries going forward. Other than that, not anything worth writing home about. […]

In NT6 (Vista), a major kernel and subsystems redesign occurred. The refactored subsystems are still used in Windows 10 for desktop applications, thus are still important, especially after the arguable ‘failure’ of Windows 8 Store Apps. The subsystem in question here is the Task Scheduler. In Windows XP and before, when an application wanted to start itself at […]

For a long time now, Bitsum has been telling users that, even in the default Windows High Performance power plan, core parking and CPU frequency scaling causes performance problems during bursting CPU loads, which are the most common type. Now, we get to say: We Told You So! That’s right, Intel’s new Speed Shift technology has […]

Windows 8 […]

When CPU affinity matters Case 1: Limit a Process’s CPU Consumption One common case where CPU affinity matters is one of CPU resource allocation. Specifically, keeping a process limited to using a certain amount of CPU time or percent of the total available. By limiting a process to specific cores, you have the ability to […]
