I'm learning Android development and I'am currently developing a game where little flys appear on the screen and the user has to click on them so they dissapear. But my method for despawning them just gives me this error: java.lang.NullPointerException: Attempt to invoke virtual method 'long java.util.Date.getTime()' on a null object reference

irtual darkness may be achievable by blocking blue wavelengths of light. . Therefore it may be possible to influence human circadian rhythms by using these lenses at night to blunt the impact of electrical light, particularly the blue light of ubiquitous television screens, by creating a virtual darkness.

In the 80386 microprocessor and later, virtual 8086 mode (also called virtual real mode, V86-mode, or VM86) allows the execution of real mode applications that are incapable of running directly in protected mode while the processor is running a protected mode operating system. It is a hardware virtualization technique that allowed multiple 8086 processors to be emulated by the 386 chip. It emerged from the painful experiences with the 80286 protected mode, which by itself was not suitable to run concurrent real-mode applications well.[1] John Crawford developed the Virtual Mode bit at the register set, paving the way to this environment.[2]

To use virtual 8086 mode, an operating system sets up a virtual 8086 mode monitor, which is a program that manages the real-mode program and emulates or filters access to system hardware and software resources. The monitor must run at privilege level 0 and in protected mode. Only the 8086 program runs in VM86 mode and at privilege level 3. When the real-mode program attempts to do things like access certain I/O ports to use hardware devices or access certain regions in its memory space, the CPU traps these events and calls the V86 monitor, which examines what the real mode program is trying to do and either acts as a proxy to interface with the hardware, emulates the intended function the real-mode program was trying to access, or terminates the real-mode program if it is trying to do something that cannot either be allowed or be adequately supported (such as reboot the machine, set a video display into a mode that is not supported by the hardware and is not emulated, or write over operating system code).

The Pentium architecture added a number of enhancements to the virtual 8086 mode. These were however documented by Intel only starting with the subsequent P6 (microarchitecture);[6] their more recent formal name is Virtual-8086 Mode Extensions, abbreviated VME[7] (older documentation may use "Virtual 8086 mode enhancements" as the VME acronym expansion).[6] Some later Intel 486 chips also support it.[8][9] The enhancements address mainly the 8086 virtualization overhead, with a particular focus on (virtual) interrupts.[6][10] Before the extensions were publicly documented in the P6 documentation, the official documentation referred to the famed Appendix H, which was omitted from the public documentation and shared only with selected partners under NDA.

In virtual 8086 mode, the basic idea is that when IOPL is less than 3, PUSHF/POPF/STI/CLI/INT/IRET instructions will treat the value of VIF in the real 32-bit EFLAGS register as the value of IF in the simulated 16-bit FLAGS register (32-bit PUSHFD/POPFD continues to GP fault). VIP will cause a GP fault on the setting of simulated IF, directing the OS to process any pending interrupts. PVI is the same idea but only affects CLI/STI instructions.

Intel VT-x brings back the ability to run virtual 8086 mode from x86-64 long mode, but it has to be done by transitioning the (physical) processor to VMX root mode and launching a logical (virtual) processor itself running in virtual 8086 mode.[14]

Westmere and later Intel processors usually[15] can start the virtual processor directly in real mode using the "unrestricted guest" feature (which itself requires Extended Page Tables); this method removes the need to resort to the nested virtual 8086 mode simply to run the legacy BIOS for booting.[16][17]

AMD-V can do virtual 8086 mode in guests, too, but it can also just run the guest in "paged real mode" using the following steps: you create a SVM (Secure Virtual Machine) mode guest with CR0.PE=0, but CR0.PG=1 (that is, with protected mode disabled but paging enabled), which is ordinarily impossible, but is allowed for SVM guests if the host intercepts page faults.[18]

The growth of hateful content online has been coupled with the rise of easily shareable disinformation enabled by digital tools. This raises unprecedented challenges for our societies as governments struggle to enforce national laws in the virtual world's scale and speed.

The entire Arbor Sightline & DDoS Threat Mitigation System deployment can be 100% virtualized, enabling organizations to take advantage of the agility and cost savings of SDN/NFV from the industry-leading DDoS Protection company.

The General Conference is the highest policymaking organ of UNIDO. The twentieth session of the General Conference (GC.20) was held from 27 November to 1 December 2023. It was hosted in the UNIDO headquarters in Vienna as a hybrid event, involving both in-person and virtual participation.

Routers: A router is a physical or virtual device that sends information contained in data packets between networks. Routers analyze data within the packets to determine the best way for the information to reach its ultimate destination. Routers forward data packets until they reach their destination node

Routers are virtual or physical devices that facilitate communications between different networks. Routers analyze information to determine the best way for data to reach its ultimate destination. Switches connect devices and manage node-to-node communication inside a network, ensuring that bundles of information traveling across the network reach their ultimate destination.

By assigning each of their customers with a virtual IBAN, all payments could be reconciled automatically, eliminating human error and saving their Ops team hours of painstaking work. They were able to spend more time focusing on growth with a persistent pain point alleviated.

Firstly, businesses can enjoy a far more streamlined approach to their payment and finance operations. Embedded account infrastructure can alleviate the need for businesses to reconcile incoming payments from their customers, for example. Instead, all parties are assigned a virtual IBAN, allowing them to receive funds directly and not rely on any referencing information. While the end user would not notice any difference in the service, Ops teams have more time available to focus on growing your business, and the possibility of human error is eliminated.

A disparity in higher education is happening, which has been exacerbated by the pandemic. Over the past year there have been heavily reported issues with laptops and technology provision, and our survey finds that only half (52 percent) of teaching at universities is currently happening remotely. If left unchecked, inequalities in student experience and provision will worsen, and there is the danger that some institutions will be left behind, particularly when matched against universities and courses set up to be virtual.

Many modern OSs and other software are fault tolerant and generally handle the odd power interruption without issue. Both Bare metal and virtualized systems can be affected by hard shutdowns, so they should be avoided when unnecessary. Virtual machines (VM) may need to be restored from backups, while bare metal systems may even require a full reinstall.

Now let's look at a more complicated scenario. In another department, let's assume virtual server VM is running on a physical server SH and is pulling data from server DB. Senior management has determined the MTD for the department's business process is 8 hours. In this case, we must ensure the RTO for the business process, which would include the RTOs for each system, does not exceed the MTD. Let's also assume recovery of virtual server VM is dependent on physical server SH being recovered first. In this case, we cannot start the recovery of VM until SH is recovered. This means we must ensure the RTOs for VM and SH together do not exceed the MTD of 8 hours. Unlike the VM dependency, server DB does not have a dependency, so it can be recovered at the same time as SH.
