3 way coin flip10/31/2022 ![]() ![]() Factors such as wind direction, the position of the sun, and other conditions may affect the decision. It is used widely in sports and other games to decide arbitrary factors such as which side of the field a team will play from, or which side will attack or defend initially these decisions may tend to favor one side, or may be neutral. In a game theoretic analysis it provides even odds to both sides involved, requiring little effort and preventing the dispute from escalating into a struggle. The coin toss at the start of Super Bowl XLIIIĬoin tossing is a simple and unbiased way of settling a dispute or deciding between two or more arbitrary options. Use in dispute resolution File:Coin toss at Super Bowl 43 1.jpg Ī legacy of this coin flip was to reduce the use of coin flips to break ties in Texas sports, instead using point-systems to reduce the frequency of ties. 3 way coin flip tv#Note that the three-way flip is 75% likely to work each time it is tried (if all coins are heads or all are tails, which occurs 1/4 of the time, the flip is repeated until the results differ), and does not require that "heads" or "tails" be called.Ī famous example of such a three-way coin flip (choose two out of three) is dramatized in Friday Night Lights (originally a book, subsequently film and TV series), where three high school football teams with identical records use a three-way coin flip – at a truck stop – to determine which two will advance to the playoffs. To choose one out of three, either reverse this (the odd coin out is the winner), or add a regular two-way coin flip between the remaining players as a second step. To choose two out of three, three coins are flipped, and if two coins come up the same and one different, the different one loses (is out), leaving two players. Three-way coin flips are also possible, by a different process – this can be done either to choose two out of three, or to choose one out of three. On most USA coins, the heads side is smoother than the tails side. The third common method of fraudulent flipping is to determine which side is up by the feel of the coin. Although it seems that this would be easily detectable, in fact, this can be done quickly and convincingly with some practice. ![]() ![]() An inclination around 45 degrees is usually satisfactory.Īnother simple way to cheat is simply to peek at the coin as it lands in your hand. The inclination must be sufficient for the coin to occupy most of the sphere that a fairly flipped coin would, while not being so great that the coin is likely to bounce when caught. The coin remains at a constant inclination to the vertical and simply rotates, or wobbles, about a vertical axis. It is not very difficult to learn to flip a coin so as to get a reliable intended result, not by controlling the number of flips but by creating the illusion that the coin is flipping.

The coin may be any type as long as it has two distinct sides it need not be a coin as such. If the outcome is unclear the toss is repeated for example the coin may come to rest upright against another object or fall down a drain. When the coin comes to rest, the toss is complete and the party who called or was assigned the face-up side is declared the winner. Depending on custom, the coin may be caught, caught and inverted, or allowed to land on the ground. The other party is assigned the opposite side. Either beforehand or when the coin is in the air, an interested party calls "heads" or "tails", indicating which side of the coin that party is choosing. Processĭuring coin flipping the coin is tossed into the air such that it rotates end-over-end several times. In England, this game was referred to as cross and pile. The historical origin of coin flipping is the interpretation of a chance outcome as the expression of divine will.Ĭoin flipping as a game was known to the Romans as navia aut caput ("ship or head"), as some coins had a ship on one side and the head of the emperor on the other. 10.1 Coin landing on its edge in fiction.7.1 Coin flipping in telecommunications. ![]()

Silent clock movement10/31/2022 ![]() To execute them requires a fourth hand that points to the date for a 31-day calendar month or to the day of the week. Some clock electric motors feature grand cycles that are monthly or weekly. The tick is a carry-over from the custom of pendulum and escapement motion (no more required but usually sought after), while the move used is a typical modern-day choice. For instance, one is usually offered the choice in between second hands that tick audibly as well as those that transform with a silent, continual move. Within these frameworks are variants, in some cases refined, that are incorporated into the movement. ![]() However, there are various other structures as well as time expansions that make use of 24-hour cycles and even much longer ones than that. Hence fundamental timekeeping is achieved, with the longest cycle being 12 hrs. For this reason, the "seconds" equipment activates a tick of the "minutes" equipment after 60 of its own ticks, as well as in a similar way the "minutes" equipment sets off the "hrs" gear. Clocks make use of equipments with the number of teeth in carefully calculated ratios to obtain the proper cycles. To attain independent turning of all the hands, their particular spindles (or shafts) have to be concentric. These hands naturally indicate symbols or figures published on the clock face. Silent clock movement full#Thus the clock electric motor shows the moment by revolving one spindle (attached to the used) a full turn every minute, another pin (minute hand) a full turn every hr, and a third spindle totally every 12 hours or 24 hours. A set of mathematical signs up partitions the natural frequency into proper timekeeping values. Its heart is a quartz crystal that vibrates (resonates) at a precise regularity derived from the crystal geometry. The modern clock motion is electronic instead of mechanical. A pendulum, in tandem with an escapement, acted as the regulator for the standard interval of timing (normally the second). ![]() The earliest ones ran purely mechanically, turning a flywheel based on the force coming from a hanging weight or snugly wound springtime. These remarkable devices are our focus in this post.Ĭlock motors and also activities are interchangeable terms that describe the very same point, one term maybe preferred by laypersons as well as the other by tradespersons. Clock activities and motors run mechanically or digitally, figuring out at any moment in time the angle subtended by each specific hand. ![]() Everything about Clock Movements and MotorsĬlock activities and electric motors are the real intestines of timepieces. ![]() Quicksync h .26410/31/2022 ![]() Yes, the four CPU cores are at 300% utilization, but obviously there's some hardware assist going on. But the ridiculously fast Mac Mini VideoToolBox H.265 video encoding doesn't use the GPU. H.264 VTBx runs on the Intel HD 630 GPU, which performs the same as the 530 one in the MBP. #QUICKSYNC H .264 FULL#(Strangely, x265 doesn't seem to use all hyperthreads to their full capacity.) Added benefit: the computer doesn't get very hot and the fans don't spin up, while they run at full blast using x264 or x265. If we can believe the Activity Monitor GPU history, VTBx uses the Intel HD 530 GPU but not the AMD 450 Pro. X264 and x265 run on the CPU, VTBx also still seems CPU-bound, but also makes use of the Intel Iris GPU.Ģ016 MacBook Pro, 2.6 GHz Core i7 (4 cores, 8 threads) Results in seconds.Ģ013 MacBook Pro, 2.4 GHz Core i5 (2 cores, 4 threads) I really don't like using average bitrate, as it can inflate file sizes unnecessarily, but it was the only option for VideoToolBox encoding. I used Handbrake's Fast 1080p30 preset but with the quality changed to an average bitrate of 1500 kbps. #QUICKSYNC H .264 MOVIE#And everyone should see this 118-year-old movie at least once, too. It has no sound so that doesn't use up additional time. I used Le Voyage Dans la Lun from 1902 for this purpose, because at 11 minutes it's big enough that the start/stop overhead won't dominate but small enough that testing doesn't take forever. So I did some testing, with very interesting results. Turns out that VideoToolBox is an Apple framework for decoding and ecoding video, using hardware features for that purpose when possible. ![]() The new thing I noticed are the (VideoToolBox) options. ![]() The default encoders in Handbrake for these codex are x264 and x265, respectively. The former is older, faster and more compatible, the latter produces smaller files. The most obvious choices are H.264 and H.265. When you encode a video, you can select between several encode options. Will an AMD RX 580 in this configuration be able to hardware decode H.264/H.I discovered something interesting in the video encoding app Handbrake today. I would love DR16 to utilise the current hardware for smooth playback - why is it not doing that? Using other apps, playback is smooth using GPU, confirming GT 1030 is able to. So it seems neither Intel Quick Sync nor GPU is used. I can confirm that GPU shows no activity when playing back 8-bit 4:2:0 H.264/H.265 (and CPU maxing out) in DR16. Why? The GT 1030 is able to hardware decode these files using other software. Here I do not have the option "Decode using H.264/H.265 using hardware acceleration" available/visiable at all. ![]() I have terrible choppy H.264/H.265 playback, in DR16. #QUICKSYNC H .264 FREE#On another older installation another place, I use the free version of DR16 with Windows 10, an Intel Ivy Bridge CPU (3770 as I recall) and an NVIDIA Geforce GT 1030. How does this match first and second bullet point above? It seems to be GPU, as the Activity Monitor show RX 580 GPU activitity when simply playing back H.264 in the Media page (ensuring it doesn't render any effects from color, fusion etc). On one installation I use with the free version of DR16 with macOS, an i7-8700K CPU and AMD RX580 GPU, I have the option (under Preferences) "Decode using H.264/H.265 using hardware acceleration" available and active.ĭoes this refer to CPU (Intel Quick Sync) and not GPU?
