It will change positive number becomes negative and negative number becomes positive. Unary minus (-) Unary minus changes the sign of the any argument. This is called 'dereferencing' the pointer. It operates on a pointer variable, and returns l-value equivalent to the value at the pointer address. The dereference operator or indirection operator, noted by asterisk (''), is also a unary operator in c languages that uses for pointer variables. Initialize p2 as the pointer to variable p1. Unary Operator in C works based on which type of operator we are applied on a variable, according to that it will perform its corresponding operation. Dereference operator ('') or Pointer Operater. It makes sense to write p or p, considering that it is a unary operator. I understand how it works when it is used in a statement. Initialize p1 as the pointer to variable v. In C, is called the indirection operator or the dereference operator. It warns when given: Null input A variable name which isnt set Expand the variable named by 1 into its value. In the case of a normal pointer, the pointer contains the address of a value. Multiple pointers require using a before each variable declaration. Algorithm Beginĭeclare a pointer p1 of the integer datatype.ĭeclare another double pointer p2 of the integer datatype. Without going mad with quoting, you can use it for many levels of indirection like so: ab bc cd echo (varexpand (varexpand a) d Or if you have more () levels of indirection you could use a loop. A pointer to a pointer is a form of multiple indirection, or a chain of pointers. So, when we define a pointer to pointer, the first pointer is used to store the address of the second pointer. double pointer indirection Nobody excuse the 'windows' code below, but this is a C++ question. Much like we can use a pointer parameter to change the actual value of the underlying argument passed in, we can pass a pointer to a pointer to a function and use that pointer to change the value of the pointer it points to (confused yet?).A pointer is used to store the address of variables. set array to 3 using our flattened array This is termed multiple indirection in this case double. Return (row * numberOfColumnsInArray) + col It is possible in C to have a pointer point to another pointer that points to a target value. Unlike normal variable which stores a value (such as an int, a double, a char). ![]() some priciples that can operate through multiple levels of indirection. programming languages (such as C) introduce the concept of variables. ![]() ![]() In these cases, we can have the function return multiple data values indirectly, using pointers. Simple math can then be used to convert a row and column index for a rectangular two-dimensional array into a single index for a one-dimensional array: int getSingleIndex(int row, int col, int numberOfColumnsInArray) While read some learning materials I found this :slightsmile: let z: &c &b.

![]() However, in selecting a prospective emergency responder, companies should also ensure that it has: ![]() In doing so, employers can prioritize their commitment to planning for confined space emergencies. To prevent the above challenges and remain compliant with OSHA standards, some companies elect to hire external confined space rescue contractors like SITEX. As a result, emergency preparedness may suffer alongside training as day-to-day operations take precedence. ![]() In addition, although a rescue team is crucial, workers are often responsible for fulfilling more than one role due to such emergencies’ infrequent nature. However, this process can be time-consuming and costly for some small and medium-sized companies. When these maintenance activities occur in tandem, companies can ensure that their confined space rescue teams are ready for any emergency. Collaborate With Local Authorities: Companies should collaborate with local emergency service responders to ensure they’re aware of site conditions and potential hazards.Survey Confined Space Conditions: Managing site conditions is critical to preventing incidents and responding to them.They must also ensure rescue workers have access to PPE when needed. Provide Personal Protective Equipment (PPE): Companies must enforce appropriate PPE use among workers to reduce the risk of emergencies.Identify Rescue Protocol: Depending on the circumstances, a rescue team will need to respond to time-sensitive or non-time-sensitive emergencies, which dictates protocol.Conduct Rescue Drills: Practicing rescue drills is one of the best ways to prepare for confined space emergencies.Although maintaining a dedicated confined space rescue team will look different for every company, certain aspects are universal: The pre-planning keeps rescuers and workers safe as all parties can more readily identify potential hazards. Employers can begin to establish a responsive, well-practiced confined space team by building site-specific scenarios into their emergency preparedness initiatives. In doing so, companies can ensure that their training meets Curriculum Standards set by governing bodies such as the National Fire Protection Association (NFPA), OSHA, and others. When forming these teams, employers must ensure that rescue training is tailored to each unique confined space. Dedicated Confined Space Rescue TeamĮstablishing a dedicated confined space rescue team is one approach companies can take to better prepare for emergencies and remain compliant. However, employers must exercise due diligence when assessing confined space risk to address potential shortcomings. This section acknowledges that companies and local emergency services may lack training in confined space rescue. If an employer plans to access local emergency services for this purpose, they must also meet requirements outlined in section 1926.1211 of the OSHA standard. The standard also requires that every employer develop and implement a confined space rescue plan that outlines emergency procedures. is not designed for continuous occupancy.has limited means of entry or exit and.According to these standards ( Subpart AA), confined space is: To eliminate this ambiguity, OSHA has developed standards for confined spaces across the construction industry. Confined Space Rescue StandardsĪlthough the term “confined space” is widely known, the exact definition isn’t always straightforward. However, no matter where companies stand with their safety initiatives, establishing a confined space rescue protocol can be time-consuming and costly. As a result, some companies may not be doing enough to keep workers safe nor compliant with local legislation. Whether it’s a lack of worker training, preparedness, or funding, confined space assessment and rescue plans can sometimes lack the resources necessary to manage risk. Unfortunately, not every company has the resources to prepare for such emergencies adequately. Of these fatalities, 60% were confined space rescuers, while instances of multiple fatalities occur most commonly among “would be” rescuers, according to the Occupational Safety and Health Administration (OSHA).Ĭollectively, these figures highlight the high-risk nature of confined space work, especially for those responding to emergencies. In addition, the Bureau of Labor Statistics Census of Fatal Occupational Injuries (CFOI) reports that from 2011 to 2018, there were 1,030 worker fatalities involving a confined space. According to the National Institute for Occupational Safety and Health (NIOSH), around 2.1 million workers enter permit-required confined spaces annually in the United States.

We’ll hear the muwashshah “Adir lana akwab” (“Pass to us the cups”), a poem by Ibn Baqi, who lived in Al-Andalus three centuries after Ziryab. The muwashshah is composed in classical Arabic while the zajal is vernacular, more improvisatory, and involves dialogue between two poets or a choral refrain. The muwashshah* and zajal** are commonly used Arab poetic forms with origins in medieval Iberia. 6 Ziryab (2:10) Ziryab by Raul Mallavibarenna, directing Musica Ficta and Ensemble Fontegara. MUSIC TRACK Músicas Viajeras: Tres culturas Musica Ficta and Ensemble Fontegara directed by Raul Mallavibarenna Enchiriadis 2013| EN-2037 Raul Mallavibarenna Tr. Certain maqamat or modes used in Arab music are said to have been introduced to Iberia by Ziryab in the ninth century. Though Ziryab’s performances survive in description only, he shaped the Andalusian traditions that we hear in medieval Spanish music as well contemporary North Africa. He is credited with adding a fifth course, or pair of strings, to the oud, the instrument that became the lute as it spread into Europe. A true “influencer” at the Ummayad court in Córdoba, Ziryab is remembered as much for his contributions to fashion and cuisine as music and poetry. Ziryab, perhaps the most famous musician of the medieval Islamic Mediterranean, worked in Abbasid, Iraq as well as Al-Andalus. In fact, medieval Arab scholars had better access to Ancient Greek texts than their Western European counterparts. Middle Eastern literary traditions also feature plenty of sung poetry. 1 Illiad 1,1 (stop at 1:11) That was scholar Stefan Hagel singing the opening of the Illiad to the phorminx, a four-string lyre, an example of a modern reconstruction of Homeric singing. Here’s a short sample from classicist Stefan Hagel of the Austrian Academy of Sciences, who’s using poetic meter along with the intonation and accent structure of Ancient Greek to inform his reconstructions of Homeric singing. Modern scholars have interpreted this ancient material in a number of ways. The Illiad, the Ancient Greek epic among the earliest examples of European literature, is more likely a “snapshot” of material in the repertoire of Ionian rhapsodes, or poets, than the creation of a single author. What has reached us is often skewed in its translation to written language over the years. As with music, the difficulty in studying early performance traditions is that so much of it was an unwritten tradition. Lots of what we think of as “old” poetry was meant to be sung. ![]() From among the Petrarchan madrigals in the second part of Willaert’s 1559 collection Musica Nova. 1 Più volte già (4:38) Singer Pur with Adrian Willaert’s five-voice setting of Francesco Petrarca’s sonnet “Più volte già dal bel sembiante humano,” (Many times now, beauty seeming kind), Canzoniere 170.

In Early Modern Europe, song composition was closely tied to the literary trends of its day. The performance of verse to instrumental accompaniment is common worldwide and likely as old as musical culture itself. From epic tales of Charlemagne’s knights to sonnets drenched in lovers’ tears, the act of singing poetry is central to many early music traditions, both improvised and on the page. ![]() When used with rimfire ammunition with lead. Possibly the most accurate of about 50 rifles I have owned. Its low weight and small dimensions make it ideal for use with sports and hunting firearms. They are that accurate in the little Ruger Precision Rimfires, which I also highly recommend. Surprise, all 15 went into the head of the nail which is barely over 1/4 inch. Being unsure, I just loaded a 15 round mag and fired all 15 at a 16 penny nail head. When first sighting in my Ruger Precision with these I could not see where I was hitting, because at 25 yards, they were all going into the same hole. You are a lucky man to own one, they are pretty rare. please contact store to confirm availability, price and shipping. After I fire I just pull the little handle back and chamber another round. We offer a variety of grains and types from the best selling brands. But I do not care, I simply shoot them as a single shot. The 22 WMR ammo cartridge is a highly effective round for shooting varmints and small predators. .22 WMR ammo tends to fire bullets weighing between 30 and 50 grains, with the 30 grain ones capable of achieving a high muzzle velocity of 2,300 feet per second-comparable to that of many centerfire calibers, albeit with a much lighter projectile. These rounds are loaded with the Hornady V-Max bullet, a polymer-tipped design that produces flat. They do not have enough power to slam the slide back and chamber a new round. Extend the range of rimfire and devastate varmints. Same with the 22LR CCI quiet loads in my 1022.

The slow-burning after-effects of Kwame’s sexual assault force him to revisit a childhood experience, one of his earliest sexual encounters, which he comes. Whatever it is, we already want to watch it. Through I May Destroy You Michaela Coel rejects victimhood and attempts to reconstruct the economy of sexual consent in a way which is multi-layered and not polarised by ‘good’ and ‘bad’, but Kwame provides an avenue for exploring where a person’s identity may mean that they are disqualified from victimhood in the first place. She recently teased that she has another show "in the back of my mind" that she was waiting to pursue until after I May Destroy You came to fruition. Weruche Opia (Terry) agreed, adding, "I hope it opens a lot of doors for other Black stories to be told and other Black creators to be able to tell their stories."Įven if we don't see more of Arabella, this will hardly be the last we see of Coel.

If I May Destroy You doesn't continue on, it will still have a lasting impact on shows to come, the stars hope. But I think when you see the final episode, you'll know," she told The Hollywood Reporter. I May Destroy You is a British black comedy-drama television limited series created, written, co-directed, and executive produced by Michaela Coel for BBC One and HBO. Meanwhile, Kwame is anguished after a consensual encounter with a man he meets online turns violent so quickly, he can't even be sure about the level of penetration. I took it as a piece of work as it is." She added that she'd "be surprised" if the show continued on.Īnd when Coel herself was asked if she planned to expand I May Destroy You, she used few words. Harriet Webb, who plays recurring character Theo, noted to Metro that she had "never spoken to Michaela about. Michaela Coel, Paapa Essiedu, and Weruche Opia in I May Destroy You. Unless we're sitting in denial, we've got to live with the events of our lives." We never eviscerate things that have happened to us. "I think it's quite short-sighted to think, 'How can we bring closure to Kwame's story?'" he added to Digital Spy. Spoilers for Episode 4 'That Was Fun' While tackling almost every nuanced layer of sexual consent and the many varied levels for violating it, Episode 4 of 'I May Destroy You' shows everyone's beloved, the wholesome Kwame, go through something excruciatingly traumatic. Indeed, a topic as sensitive as this shouldn't be exploited into a franchise, and it's "short-sighted" to assume closure can be forced into the narrative, Essiedu says. While the premise follows rising writer Arabella (Coel) as she puts together the pieces from the night she was sexually assaulted, the story also sheds light on her friends' own experiences with sexual abuse and trauma. Season one episodes will air on Sundays at 10:30pm ET/PT and will finish up its 12 episode run on August 24th. On I May Destroy You, Consent Isn't Binary And Neither Is Justice Arabella and Kwame's respective assaults offer a devastating look at which survivors we're more likely to listen to. I think we're at least going to sit back and let people enjoy this before we think about what the next step would be." HBO’s set to launch the new half-hour series I May Destroy You on June 7, 2020. Tyrone inviting Kwame over with a hidden intention is arguably false pretence, as this is not the scenario Kwame had consented to over Grindr. It also wouldn’t be fair to say the show is just about Arabella’s healing process anymore. He added, "We were all really sure and comfortable in the story we were telling, and we feel like we've done a good job in doing that. I May Destroy You isn’t in a rush to unlock Arabella’s journey. ![]() Michaela Coel Turned Down $1 Million Netflix Deal.No sexual violation of Kwame took place in this instance, but the betrayal of consent was performed by a meddling friend who was projecting a fantasy within the social world she created. Despite Kwame attempting to speak on how Nilufer had effectively "forced" him to have sex with her, she refuses to accept that Kwame could ever be a victim in the way that she has been - even going as far as to say "being vulnerable doesn't mean you can make other people vulnerable, doesn't mean you can put other people through pain." Ironically, Arabella violated Kwame's boundaries and had not established consent when she locked him in a bedroom with her friend, Jamal, at Terry's party, with the expectation that they would hook-up. She accuses Kwame of having sex with Nilufer under false pretenses, and in line with her crusade against sexual abusers she rebukes the very idea that she accepted a person like him to have intimate proximity to her. What's key here for reframing consent is also in how Arabella rejects Kwame from the personal social environment she has constructed. ![]() The second features a photograph by Matt Dieterich of Pittsburgh, PA, of Mount Rainier National Park in Washington State (see his time lapse video).

The simplest way to check your router's public IP address is to search "what is my IP?" on a search engine. Figuring out your provider and general location based on IP address is as simple as consulting a public list. That's because ISPs dole out a range of IP addresses. ![]() What you'll also find is that there's lots of information about you attached to that IP address, specifically your ISP's name and your general location (called a GeoIP). This can be particularly handy for things like VoIP calls or remote control software. There may come a time when you need to know the IP address of your router, as assigned by your ISP. That's all good to know, but how do you find your IP address? That offers a lot more than 4 billion addresses. So, there's also IPv6, which is 128-bit, with eight groups of four hexadecimal digits (numbers and lower-case letters mixed), all separated by a colon (for example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334). However, this limited the world to a possible 4+ billion IP addresses, which isn't enough. This format is used by IP version 4 (or IPv4). IP addresses are typically in the same format as a 32-bit number, shown as four decimal numbers each with a range of 0 to 255, separated by dots-each set of three numbers is called an octet. You could also get a static IP for your router-which is handy if you run a web server, for example, but expect your ISP to charge extra. However, you can set up "static IP addresses" on computers so they never change-this can be important for some kinds of network communications, especially if it's crucial to be able to find that same node over and over. If you have an IP address assigned, it's typically considered a "dynamic IP" because it could be temporary the router might give the node in question a different IP address at a later time (same with the IP address your ISP gives your router). The protocol used by the router to assign IP addresses is called Dynamic Host Control Protocol (DHCP). That way, all the nodes on the internal network can communicate. (That's why it's called a router.)Ĭomputers on internal networks, be it Wi-Fi or Ethernet, at home or in the office, have their own IP addresses assigned to them (usually by the router). So even though a website only sees a request come in from the IP address on the router, the router knows how to route the information to/from the computer. That IP address is generally assigned to the router by your internet service provider (ISP) the router, in turn, handles all the traffic from your computers and other devices out to the internet. One is how the computer talks to the internet at large, which is the IP address of your router. When it comes to your computer(s), there are actually several IP addresses involved. It's all called IP for short, and TCP/IP is the language used for communication by most networks. The "IP" stands for "internet protocol," which is part of the Transmission Control Protocol/internet Protocol (TPC/IP). Computers prefer numbers, and the numbers they use as identifiers are called IP addresses. Networks, and the internet, don't identify computers (of any size, even your smartphone) by the name you give them.
