-Leela beloved,The case of women cmiruiccsion is an interesting example of cultural norms and liberal perspectivesThere is nothing wrong with having an opinion and ultimately rejecting a specific cultural practice based on one's take. for example Bush's war to bring democracy to Iraq. In the place that we live in we it is inconceivable that someone might prefer a different ​kind of regime or that someone might have values that trump the perception of freedom that comes with what we conceive ​to be a democracyhoweverit is a judgement that is better executed after we know about the core values ​and the priorities of the Iraqi people, of whatever culture we think that we should enforce our own worldview onFemale cmiruiccsion ​is probably ​(along perhaps with female infanticide ) one of the most visceral propositions that encounter immediate disgust and rejection among the like of us (me included). But it is a custom that exists in many societies ​ none of which a society that do not have the equivalent practice for menGenetile modification in most of these societies is also reflecting a perception of body and pureness, a tradition that has its own history and values that goes well beyond the shallow, two-dimensional portrayals of the ritual in the Westa mutilation of the female ​to enhance male dominance and horrific control over women'​s legitimate sexual urgesWhich brings us back to the question of how do we pass judgement on practices of other cultures? For myselfI'm not a cultural absolutist (meaning I don't think that one can not pass such judgementsI believe that one needs to learn enough about such practices from an emic perspective ​(meaning one should learn about the practice from an "​insider"​ point-of-viewthat reflects real learning rather than the common media or other outsider portrayalsTake for example female cmiruiccsionThis is a practice common ​in many African countries, in some of the East Africa states it involves upward of 90% of the womenIn the vast majority of the practices ​(which by the way vary considerably between different communitiesthe practice does not involve the removal of any organ (clit or lipsand in many of the societies it involves a single incision to the lips which heals quite fast and leaves no lasting effects. In many of the societies the women are responsible for the execution of the practice in a form of a rite of passage to adulthood ​and this practice is more symbolic than surgical.  ​There are many incidents of horrifying examples of this practice which make my skin crawl and the stomach turnThere are many other indications of pride in the practice as many believe it reflects some of the core values that they hold dearlyA Somalian women who lived in the US since childhood, decided to go back to Somalia and have this practice done following her graduation from HarvardFor her it meant very different thing than for many of the girls who are forced ​to go through that by force or by social pressure ​(in some societies one cannot marry unless she had that done). Before we condone ​(or reject for that matterthis practice (and otherwe should learn about the actual detailsHow does it effect most women who experience thatsociallypsychologicallyand physicallyOne would actually find hardly any systematic scientific accounts for that phenomenonWe should learn how this practice is carried out and by whomSensational portrayals ​and selective accounts can hardly be considered a legitimate basis for passing judgement on an entrenched cultural practice  At the end we can still have an opinion on that (which would likely be more nuanced and informedand hold on to our own core values in a way that suggest the universalism ​of themthere are no good cultural specific basis to perform act X regardless of the local cultural valuesBut through this process we might just learn about the other from eye level and not from a perspective filled with underlying tones of the superiority that so many of us Westerns still experience implicitly when we look at "​primitive"​ cultural practices which we know so little about.  ​Just a thought ​+

 +In an audio-related context, some kind of "​real-time"​ is 
 +preferable, in order to gain low latencies. 
 +(HereLatency ​is the time elapsed between audio-input ​and audio-output (including processing in between)
 + 
 +The simplest way to obtain lower latency than usual, ​is to **use an optimized linux audio distribution ​(see below)**. 
 +These generally utilize real-time patched kernels, with additional system optimisations,​ such as priority settings, etc.
