... Forum: The Linux Kernel Hackers' Guide . ... Before kernel version 1.0, both forms of sleep_on() just waited on a task_struct pointer variable, setting that variable to point to the last caller of sleep_on(). wake_up() would thus only directly awaken the last caller of sleep_on(); that caller was responsible for waking up the previous caller (a pointer to which it had saved), and so on down the chain. ... If the task is at the top of the "wait stack", the behavior is just like a call to wake_up(). ...

. Computer Ephemeris. Lunar pericenters. Explanations. This page contains the table with 12 rows (one row per month) and 4 columns, labeled with 'Perigee' for moments of perigee passage and 'Apogee' for moments of apogee passage. Each cell in the table contains three numbers: day, (month is possibly to read as first word in the same row), hours and minutes of the phenomenon. Hours and minutes are subdivided by column symbol (':').

... In this review, we shall call any gravitationally-bounded object having an angular momentum and intrinsic magnetic field   by the term ``gravimagnetic rotator''   or simply, rotator. In order to specify the intrinsic properties of the rotator, three parameters are sufficient - the mass M , the total angular momentum ( I is the moment of inertia and is the angular velocity), and the magnetic dipole moment (see Figure  3 ). ... Figure 3: Schematic representation of a gravimagnetic rotator. ...

. To the IUM main page . This talk will be on joint work with Tom Braden. A moment graph is a graph mapped to Euclidean space so that all of the edges are sent to straight lines. Under suitable hypotheses, an action of a torus on a space determines a moment graph, and the intersection homology of the space can be read off from the moment graph, in a way that is algorithmic and functorial.

... For Graphic-boards I'd say the best cheap board fitting perfectly on a good Multisync-15 like the Samsung SyncMaster 15Gli, is the SPEA V7 Mirage P64 with Trio64 Chipset and 2M DRAM. ... For SCSI I'd take the DPT rather than the (much cheaper and very fast) NCR53c810 in case you plan to use SCSI-Tapes a lot. ... The SPEA V7 Mirage P64 PCI with 2M DRAM would be a good choice, since it uses the Trio64 S3 Chip, which is well supported by XFree86(tm)-3.1.1, quite cheap to buy and fast, too. ...
