Query: What is a race condition?
A race condition or race hazard is the behavior of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events. It becomes a bug when one or more of the possible behaviors is undesirable.
An hour before the race the conditions significantly worsened, and Prost and Berger's proposal was being seriously considered by a lot of drivers. World Champion Ayrton Senna who wanted to start despite the appalling conditions. With McLaren's court action over his disqualification in Japan still pending the championship was technically not yet settled and to keep any chance of retaining his World Drivers' Championship he had to win the race. Senna later privately confessed to a friend that he thought it was too dangerous to race but that he was a contracted driver and racing was what he was paid to do. He also said that championship or not, he believed Prost did the right thing by not taking the restart as he had nothing to gain by driving in such conditions. The drivers' arguments failed and it was agreed the race would go ahead. It also emerged that while still in his car Senna had been approached by Boutsen to get his thoughts about starting. Senna reportedly agreed the race should not go ahead, but he was bound by both his contract and the championship situation to start.
The wording that Mills chose in 1933 led to the NCU's long civil war with a later rival body, the British League of Racing Cyclists. Mills wrote: "No massed start race shall be permitted, other than on an enclosed circuit, unless the course is closed under statute by the competent authority, to other vehicular traffic." Nine years later, in October 1942 and after the BLRC had broken away from the NCU because of that insistence on closed roads, Mills regretted what he had done: "In 1933 it was impossible to foresee the future... the war, the changing conditions on the road, the decline of track sport, the growing demand for massed start under real road conditions. My notes covered conditions as they existed in 1933."
One condition of the race was that cycle traders were prohibited from offering a bonus or other inducement to competitors in the event of winning the race on his machine. It is not clear what this condition was meant to achieve and it did not stop cycle traders advertising the success of riders on their bicycles.
The 135-mile Badwater Ultramarathon is touted as the World’s Toughest Race, a non-stop race beginning at Badwater, Death Valley, and ending at the Mt. Whitney Portal. The race features non-stop running through extreme elevation climbs (17,000’ cumulative vertical ascent), 100 °F temperatures during the day, cooler temperatures at night, and what many would consider adverse overall conditions. Lewis completed the race in under 24 hours (23:52:55), about 50 minutes ahead of the second place finisher, Australian Grant Maughan, with an average 10:30 pace.
In 2011 the race started in damp conditions but as the event unfolded the conditions improved giving perfect conditions for mountain bike racing.
While establishing himself as one of America's leading jockeys, he was diagnosed with what is now known as type 1 diabetes. Only a few years earlier, before the discovery of insulin, such a diagnosis would have been fatal. Because of his condition, and the nature of diabetes management in the 1930s and 1940s, Woolf had to regulate his weight to avoid rapid dieting. His racing success allowed him to accept only a few mounts each week, riding only 150–200 races each year compared to as many as a thousand rides other jockeys might undertake, and for years he maintained top physical condition. Despite his limited number of races and a relatively short career, Woolf won ninety-seven major stakes races around the United States, including the Hollywood Gold Cup Stakes, the American Derby and the Belmont Futurity Stakes three years running.
The Boston Marathon took place in what many considered to be the worst weather in its 110-year history. Race officials held serious talks about whether or not to cancel the race. The men's race had the slowest winning time in thirty years (1977). In the women's race, "[t]he rainy and windy conditions led to the slowest winning time since 1985".
But what was secured to colored citizens of the United States as between them and their respective states—by the grant to them of state citizenship? With what rights, privileges, or immunities did this grant from the nation invest them? There is one, if there be no others—exemption from race discrimination in respect of any civil right belonging to citizens of the white race in the same state. That, surely, is their constitutional privilege when within the jurisdiction of other states. And such must be their constitutional right, in their own state, unless the recent amendments be 'splendid baubles,' thrown out to delude those who deserved fair and generous treatment at the hands of the nation. Citizenship in this country necessarily imports equality of civil rights among citizens of every race in the same state. It is fundamental in American citizenship that, in respect of such rights, there shall be no discrimination by the state, or its officers, or by individuals, or corporations exercising public functions or authority, against any citizen because of his race or previous condition of servitude. In "U.S. v. Cruikshank", 92 U. S. 555, it was said that 'the equality of rights of citizens is a principle of republicanism.' And in "Ex parte Virginia", 100 U. S. 344, the emphatic language of this court is that 'one great purpose of these amendments was to raise the colored race from that condition of inferiority and servitude in which most of them had previously stood, into perfect equality of civil rights with all other persons within the jurisdiction of the states.' So, in "Strauder v. West Virginia", Id. 306, the court, alluding to the fourteenth amendment, said: 'This is one of a series of constitutional provisions having a common purpose, namely, securing to a race recently emancipated, a race that through many generations had been held in slavery, all the civil rights that the superior race enjoy.' Again, in "Neal v. Delaware", 103 U. S. 386, it was ruled that this amendment was designed, primarily, 'to secure to the colored race, thereby invested with the rights, privileges, and responsibilities of citizenship, the enjoyment of all the civil rights that, under the law, are enjoyed by white persons.'
The 2009 Supersport Race 2 was won by Michael Dunlop in 1 hour, 14 minutes and 34.80 seconds at an average race speed of 121.416 mph. In the mixed race conditions Michael Dunlop commented that;- "My dad gave me the knowledge. I went as quickly as I dared in the damp conditions later on. I had to go for it. It was my spare bike, my better one blew-up in the first couple of miles yesterday. This makes up for all the disappointment...I have been pretty relaxed apart from that. It's been like Paddy's on Tour." The 2009 Supersport TT Race 2 was the second win on the Snaefell Mountain Course after Michael Dunlop had won the 2006 Newcomers Manx Grand Prix and was the 34th win for the Dunlop family over a period of 32 years. In second place was the New Zealander Bruce Anstey at an average race speed of 120.580 mph the margin just 0.71 seconds from the late challenge from Conor Cummins. Also, Bruce Anstey reflected about the mixed conditions and after three non-race finishes said;- "We finally got the gremlins sorted out and I was just glad to cross the finish line – the conditions were very wet and slippery early on but got drier as the race went on. Michael got the move on the first lap and there was no getting him back. In third place was Conor Cummins at an average speed of 120.561 and said of the lap 3 problem;- "I'm really not sure what went wrong with the bike at the end of lap three but it seems OK now. I'm delighted with third but it would be nice to go two better.
In this case of a race condition, the concept of the "shared resource" covers the state of the network (what channels exist, as well as what users started them and therefore have what privileges), which each server can freely change as long as it signals the other servers on the network about the changes so that they can update their conception of the state of the network. However, the latency across the network makes possible the kind of race condition described. In this case, heading off race conditions by imposing a form of control over access to the shared resource—say, appointing one server to control who holds what privileges—would mean turning the distributed network into a centralized one (at least for that one part of the network operation).
Conditions races are distinct from handicap races, for which the weights carried are laid down by an official handicapper to equalise the difference in ability between the runners. In Great Britain, for example, the British Horseracing Authority's rules define a conditions race as being one "which is none of the following; a Handicap Race or a Novice Race, a race restricted to Maiden Horses, or a race governed by Selling or Claiming provisions."
Conditions races are horse races in which the weights carried by the runners are laid down by the conditions attached to the race. Weights are allocated according to the sex of the runners, with female runners carrying less weight than males; the age of the runners, with younger horses receiving weight from older runners to allow for relative maturity, referred to as weight for age; and the quality of the runners, with horses that have won certain values of races giving weight to less successful entrants.
In the works of John H. Van Evrie, a Northern supporter of the Confederacy, the term was interchangeable with white supremacy, notably in "White Supremacy and Negro Subordination, Or, Negroes a Subordinate Race and (so-called) slavery its normal condition" (1861). In "Subgeneation: the theory of the normal relations of the races; an answer to miscegenation" (1864) Van Evrie created the words "subgen" to describe what he considered to be the "inferior races" and "subgeneation" to describe the ‘normal’ relation of such inferior races to whites, something which he considered to be the "very corner-stone of democracy"; but these words never entered the dictionary.
Conditioned for racing by future U. S. Racing Hall of Fame trainer Jack Joyner, Jamestown raced against very strong opponents in 1930 and 1931 when he was part of what the "Chicago Tribune" newspaper called the "big four" in racing, which included Twenty Grand, Mate, and Equipoise.
The condition of a race track plays an important role in the performance of horses in a race. The factors that go into determining race track condition include the surface conditions, type of surface, and track configuration. The surface conditions are influenced by the type of surface factoring in soil type, and if the track is dirt, turf, artificial surface; plus surface density, porosity, compaction and moisture content.
The original Race Instructions issued by the SNG Race Committee (RC) defined the maximum allowed wave height, maximum wind velocity and maximum variation of wind direction across the course in order for a race to be started and completed. It is unusual for specific weather conditions to be inserted in the race instructions because this is usually left to the discretion of the PRO to start a race in conditions which are deemed to be safe and/or allow the race to be completed within the time limit. The consensus of most of the commentators at the time was that the wind conditions defined in the race instructions were artificially low and designed to favour Alinghi 5 which was generally thought to have a better performance than USA 17 in light airs. GGYC appealed these specific limits to the ISAF International Jury who ordered them removed from the Notice of Race, but noted "that the RC has the obligation to comply with appropriate safety and legal obligations when making a decision to start or continue a race."
At Flemington Racecourse on 5 November What A Nuisance started at odds of 15/1 in a field of twenty-three runners for the Melbourne Cup. The race was sponsored for the first time by the Foster's Group and carried record prize-money of over A$1,000,000, making it the most valuable race ever run in Australia. The race attracted a crowd of 79,126 which included the Prince and Princess of Wales. Ridden by the veteran Pat Hyland, What A Nuisance was drawn badly but appeared well-suited by the wet conditions. Hyland allowed the gelding to relax in the early stages before producing a strong late run to win by a nose from the mare Koiro Corrie May.
Race conditions arise in software when an application depends on the sequence or timing of processes or threads for it to operate properly. As with electronics, there are critical race conditions that result in invalid execution and bugs. Critical race conditions often happen when the processes or threads depend on some shared state. Operations upon shared states are critical sections that must be mutually exclusive. Failure to obey this rule opens up the possibility of corrupting the shared state.
Adjusted for previous SAT scores, subjects in the non-diagnostic-challenge condition performed significantly better than those in the non-diagnostic-only condition and those in the diagnostic condition. In the first experiment, the race-by-condition interaction was marginally significant. However, the second study reported in the same paper found a significant interaction effect of race and condition. This suggested that placement in the diagnostic condition significantly impacted African Americans compared with European Americans.
It rained before the start of the race, but by the time the race started, the track was already drying. The teams had to decide on what kind of tires to use. Siffert, Rodriguez and Ickx chose mix condition tires; most of the big bangers chose rain tires.
The 1968 German Grand Prix was a Formula One motor race held at the Nürburgring on 4 August 1968. It was race 8 of 12 in both the 1968 World Championship of Drivers and the 1968 International Cup for Formula One Manufacturers. The race was held in extremely wet and foggy conditions, and British driver Jackie Stewart, racing with a broken wrist, won the race by a margin of four minutes in what is widely considered to be one of the greatest victories in the history of Formula One.
The club competes at a number of regattas and head races throughout the academic year (September - August). Prior to Christmas the club's main focus is the Bristol Head Race. This event provides developing crews with the academic year's first taste of inter-university competition and the beginner crews with the first chance to apply what they have learnt in race conditions. The club also sends its athletes to the National Indoor Rowing Championships.
Many software race conditions have associated computer security implications. A race condition allows an attacker with access to a shared resource to cause other actors that utilize that resource to malfunction, resulting in effects including denial of service[5] and privilege escalation.[6][7]
Bred and raced by George D. Widener, Jr., she was conditioned for racing by future U.S. Racing Hall of Fame trainer Syl Veitch.
