According to one embodiment of the present disclosure, an approach is provided in which a processor selects a page of data that is compressed by a first compression algorithm and stored in a memory block. The processor identifies a utilization amount of the compressed page of data and determines whether the utilization amount meets a utilization threshold. When the utilization amount fails to meet the utilization threshold, the processor uses a second compression algorithm to recompresses the page of data.

Multi-level memory compression

Each time a currently scheduled virtual machine (VM) accesses a hardware resource over a bus for the hardware resource via the currently scheduled VM running on a processor, a hardware component adjusts a bandwidth counter associated with usage of the bus for the hardware resource, without involvement of the currently scheduled VM or a hypervisor managing the currently scheduled VM. Responsive to the bandwidth counter reaching a threshold value, the hardware component issues an interrupt for handling by the hypervisor to maintain bandwidth quality-of-service (QoS) of bus bandwidth related to the hardware resource. Upon expiration of a regular time interval prior to the bandwidth counter reaching the threshold value, the hardware component resets the bandwidth counter to a predetermined value associated with the currently scheduled VM, without involvement of the currently scheduled VM or the hypervisor; the hardware component does not issue an interrupt. The hardware resource can be memory.

Maintaining hardware resource bandwidth quality-of-service via hardware counter

Embodiments of the invention relate to implementation of an intermediate trusted state of an electronic account based upon questionable account communication(s). A profile of malicious or unauthorized activity is created, and a profile of account activity is created. As account activity takes place, the activity is assessed against one or both of the profiles to statistically determine if the activity resembles that associated with malicious or unauthorized intent. The state of the account is placed in the intermediate trusted state if the activity statistically matches the unauthorized activity profile. An authentication activity enables the trusted state to be removed and for the account activity to resume.

Intermediate trust state

A method, system, and computer program product for selecting memory pages for compression based on a population count associated with their datasets are disclosed. For example, a dataset stored in a memory page of an uncompressed memory is analyzed. Based on the analyzing, a population count associated with the dataset is identified. The population count is compared to at least one threshold. Based on the comparing, the memory page is selected or rejected for compression.

A method which controls modification of passwords. An end user designates, in advance, a universe of social media contacts such as friends on social media web sites such as Facebook and LinkedIn. Contacts so identified are used as a set of potential identity verifiers. In order to enable a reset or modification of an account password, a subset of the universe is required to assert that they have verified the identity of the user requesting to reset a password. Such verification can be accomplished by varying means by those to whom an inquiry has been directed.

Controlled password modification method

Apparatus which control modification of passwords by implementing a procedure by which end user designates, in advance, a universe of social media contacts such as friends on social media web sites such as Facebook and Linkedln. Contacts so identified are used as a set of potential identity verifiers. In order to enable a reset or modification of an account password, a subset of the universe is required to assert that they have verified the identity of the user requesting to reset a password. Such verification can be accomplished by varying means by those to whom an inquiry has been directed. Te apparatus may be in the form of a computer system or a computer readable storage medium.

A method and apparatus for managing collaborations. Requests are received by a computer for collaboration on a topic. A set of experts is identified by the computer having expertise in the topic for the collaboration and having activity prior to the collaboration relating to the topic to predict a likelihood of participation by the respective expert in the collaboration. The set of experts are identified from searching a number of collections of information.

Predictive collaboration management

A method, system, and program are provided for managing flexible events within an electronic calendar. A calendaring controller schedules fixed events requiring a fixed time slots and flexible events that are flexible for scheduling over a particular time period for a particular duration, wherein the particular time period is greater than the particular duration. The calendaring controller sets each flexible event at a particular time slot within the particular time period for the particular duration. Responsive to the calendaring controller detecting a request for a new event for an additional time slot overlapping the particular time slot, the calendaring controller repositions the flexible event to at least one other time slot of the particular duration during the particular time period to allow for scheduling the new event during the additional time slot.
