There are other ways to guard against password cracking. The simplest is well known and used by credit cards: after three unsuccessful attempts, access is blocked. Alternative ideas have also been suggested, such as doubling the waiting time after each successive failed attempt but allowing the system to reset after a long period, such as 24 hours. These methods, however, are ineffective when an attacker is able to access the system without being detected or if the system cannot be configured to interrupt and disable failed attempts.

This practice poses a serious problem for security because it makes passwords vulnerable to so-called dictionary attacks. Lists of commonly used passwords have been collected and classified according to how frequently they are used. Attackers attempt to crack passwords by going through these lists systematically. This method works remarkably well because, in the absence of specific constraints, people naturally choose simple words, surnames, first names and short sentences, which considerably limits the possibilities. In other words, the nonrandom selection of passwords essentially reduces possibility space, which decreases the average number of attempts needed to uncover a password.
In this variant, when a player picks up the blind, any player who was not given the opportunity to pick up the blind and who is not the picker's partner may knock or crack by knocking the table with their fist. This automatically doubles the point values determining the score when the game ends. In the aces variant, the crack must take place after the ace has been called but before the first card is played.
A variant of the leaster is the moster, which is played the same as a leaster, but after the hand is scored, the player who took the most points pays out (as if for a simple loss) to all the rest of the players. Thus, in a five-player game, the affected player loses four points and the opponents get one each, unless the score is doubled by other means (cracking, etc.). The exception is taking all of the tricks, which is still scored as a win by the player doing so.
Ostapenko surged back into the Top 20 after a stellar February, in which the Dubai title was bookended by semifinal runs in St. Petersburg and Doha. But the Latvian was tripped at the first hurdle in Indian Wells by perennial upset artist Rogers, who now owns 21 victories over Top 20 players even though she is yet to crack the Top 30 herself.

Race has been and remains inextricably involved in drug law enforcement, shaping the public perception of and response to the drug problem.[16] A recent study in Seattle is illustrative. Although the majority of those who shared, sold, or transferred serious drugs[17] in Seattle are white (indeed seventy percent of the general Seattle population is white), almost two-thirds (64.2%) of drug arrestees are black. The racially disproportionate drug arrests result from the police department's emphasis on the outdoor drug market in the racially diverse downtown area of the city, its lack of attention to other outdoor markets that are predominantly white, and its emphasis on crack. Three-quarters of the drug arrests were crack-related even though only an estimated one-third of the city's drug transactions involved crack.[18] Whites constitute the majority of those who deliver methamphetamine, ecstasy, powder cocaine, and heroin in Seattle; blacks are the majority of those who deliver crack. Not surprisingly then, seventy-nine percent of those arrested on crack charges were black.[19] The researchers could not find a "racially neutral" explanation for the police prioritization of the downtown drug markets and crack. The focus on crack offenders, for example, did not appear to be a function of the frequency of crack transactions compared to other drugs, public safety or public health concerns, crime rates, or citizen complaints. The researchers ultimately concluded that the Seattle Police Department's drug law enforcement efforts
reflect implicit racial bias: the unconscious impact of race on official perceptions of who and what constitutes Seattle's drug problem . . . . Indeed, the widespread racial typification of drug offenders as racialized "others" has deep historical roots and was intensified by the diffusion of potent cultural images of dangerous black crack offenders. These images appear to have had a powerful impact on popular perceptions of potential drug offenders, and, as a result, law enforcement practices in Seattle.[20]
The racial dynamics reflected in Seattle's current drug law enforcement priorities are long-standing and can be found across the country. Indeed, they provided the impetus for the "war on drugs" that began in the mid-1980s.[21] Spearheaded by federal drug policy initiatives that significantly increased federal penalties for drug offenses and markedly increased federal funds for state anti-drug efforts, the drug war reflected the popularity of "tough on crime" policies emphasizing harsh punishments as the key to curbing drugs and restoring law and order in America.[22] The drug of principal concern was crack cocaine, erroneously believed to be a drug used primarily by black Americans. The use of cocaine, primarily powder cocaine, had increased in the late 1970s and early 1980s, particularly among whites, but powder cocaine use did not provoke the "orgy of media and political attention"[23] that occurred in the mid-1980s when a cheaper,[24] smokable cocaine in the form of crack appeared.[25]
Although the use of crack was by no means limited to low-income, urban, minority neighborhoods,[31] it was those neighborhoods which more visibly suffered from crack addiction, and the nuisance and violence that accompanied the struggle of different drug-dealing groups to establish control over its distribution in the 1980s and 1990s.[32] The dismay of local residents, however, was exceeded by the censure and outrage from outsiders fanned by sensationalist media stories and by politicians eager to seek electoral advantage.[33] With politicians and the media focused on the putative effects of crack in inner-city neighborhoods-although many of those effects were subsequently proven to have been greatly exaggerated or just plain wrong[34]-those neighborhoods became and remain the principal "fronts" in the war on drugs.
That response, most notoriously, included the federal Anti-Drug Abuse Act of 1986 and the Anti-Drug Abuse Act of 1988, which imposed far higher penalties for possession or sale of crack cocaine than powder cocaine, as well as state laws that required prison sentences even for low level drug offenses.[37]
The legislative and law enforcement responses to crack "cannot be attributed solely to objective levels of criminal danger, but [also reflect] the way in which minority behaviors are symbolically constructed and subjected to official social control."[38] Law enforcement efforts against crack in poor minority neighborhoods reinforced control of the urban "underclass," a group deemed by the political and white majority to be particularly "dangerous, offensive and undesirable."[39] The conflation of the underclass with crack offenders meant the perceived dangerousness of one increased the perceived threat of the other. Urban blacks, the population most burdened by concentrated socio-economic disadvantage, became the population at which the war on drugs was targeted.[40]
According to the 2006 surveys conducted by the federal Substance Abuse and Mental Health Services Administration (SAMHSA), an estimated 49% of whites and 42.9% of blacks age twelve or older have used illicit drugs in their lifetimes; 14.5% of whites and 16% of blacks have used them in the past year; and 8.5% of whites and 9.8% of blacks have used them in the past month.[42] Because the white population is more than six times greater than the black population, the absolute number of white drug offenders is far greater than that of black drug offenders.[43] SAMHSA estimates that 111,774,000 people in the United States age twelve or older have used illicit drugs during their lifetime, of whom 82,587,000 are white and 12,477,000 are black.[44] Even among powder and crack cocaine users-which remain a principal focus of law enforcement-there are more whites than blacks.[45] According to SAMHSA's calculations, there are 27,083,000 whites who have used cocaine during their lifetime, compared to 2,618,000 blacks and, indeed, 5,553,000 whites who have used crack cocaine, compared to 1,537,000 blacks.[46] 2ff7e9595c
