This e-book is a realistic overview to assist you start migrating your current personal home page code from the expend of the older MySQL extension to the more moderen PDO database abstraction extension. I received’t travel into the entire features obtainable to you with PDO, however i'll share with you the basic strategies you're going to exigency to know and offer a pair of guidance so your migration can breathe as short and painless as feasible.
First, you should understand where PDO sits in the personal home page ecosystem. There are in fact three ways to interface with a MySQL database from php: the first is with the MySQL extension, the 2nd is with the MySQLi extension and the third is with PDO.
The MySQL extension is the oldest of the three and become the common alternative developers used to speak with MySQL. The extension is now being deprecated in want of the other two options as a result of advancements made in more recent releases of both personal home page and MySQL.
MySQLi is the “improved” extension for working with MySQL databases. It takes expertise of aspects that are available in more recent models of the MySQL server, exposes both a feature-oriented and an object-oriented interface to the developer and a does few other nifty things. If PDO isn’t remedy in your project, then this is the extension you'll want to breathe the usage of.
Then most recent extension is PDO, which stands for “php records Objects.” PDO presents an API that consolidates most of the performance that became up to now unfold across the main database entry extensions, i.e. MySQL, PostgreSQL, SQLite, MSSQL, and so on. The interface exposes high-level objects for the programmer to work with database connections, queries and consequence units, and low-degree drivers perform verbal exchange and aid handling with the database server. a lot of dialogue and work is going into PDO and it’s regarded the applicable way of working with databases in up to date, skilled code.
When feasible, i recommend americans skip the middle man so that you can communicate and migrate from the MySQL extension to PDO in preference to to MySQLi. PDO offers a constant API to work with a number of databases, so that you received’t should alter your personal home page code if you ever should expend a further database. also, whereas the MySQLi extension is at the flash maintained, there’s always the opportunity it could breathe deprecated in the future. deciding on to migrate to PDO now capability you gained’t ought to migrate to it later and supplant your code twice. i expend PDO and furthermore you should still too!setting up and Configuring PDO
once you’ve determined you are looking to modernize your code, you’ll should Make sure PDO is properly set up and configured. As i discussed before, PDO carries two components: the extension itself which exposes the interface and a low-degree database-specific driver. Drivers exist for a starting to breathe list of databases, together with MySQL.
PDO and the SQLite-specific driver may still breathe a Part of the default php setting up as of version 5.1.0 and the MySQL-specific driver would still deserve to breathe reserve in, but most Linux distributions commonly occupy diverse ideas how Hypertext Preprocessor may still breathe compiled and packaged. in reality, lots of the principal distros now package the MySQL extension, the MySQLi extension and the MySQL PDO driver collectively within the identical package. chances are tall in case you’re the usage of MySQL on such a apparatus then PDO is probably already installation for you.
On home windows, the entire PDO drivers are covered in the ext folder that became created in the event you installed Hypertext Preprocessor from the pre-compiled binary’s archive. You most effective deserve to supplant your personal home page.ini with the aid of including or uncommenting the line:extension=php_pdo_mysql.dll
It’s always feasible to bring together the drivers yourself in a worse-case scenario. breathe unavoidable the MySQL libraries and other pile information are installed and purchasable to your build environment because most complications that people arrive upon while trying to collect some thing results when the compiler can’t ascertain a number of header information or libraries to link in opposition t.fundamental Querying
The simple workflow for the expend of the MySQL extension’s features to work with a database can breathe concept of as a 5-step system:
With PDO, the very technique can furthermore breathe followed and looks like this:<?personal home page // Step 1: establish a connection $db = new PDO("mysql:host=localhost;dbname=testdb", "testusr", "secretpass"); // Step 2: assemble a question $question = "select * FROM foo where bar = " . $db->quote($zip); // Step three: route the query $outcome = $db->query($question); // Step 4: Iterate over the consequences whereas($row = $influence->fetch(PDO::FETCH_ASSOC)) print_r($row); // Step 5: Free used components $influence->closeCursor(); $db = null;
The system of connecting to the server and picking the database with PDO is performed using a DSN as a substitute of the myql_connect() and mysql_select_db(). A DSN is an abbreviation for “facts supply identify” which is a string that identifies which PDO driver to Make expend of to talk with the database and conveys any basic connection information such because the host server, connection port and database name. depending on your database, the format of the DSN you deliver may fluctuate. The main add-ons captious for each driver are documented on personal home page.internet, however sadly they are now and again challenging to find. i like to recommend using the web page’s search characteristic to search for the time epoch “DSN” in the online documentation.
also breathe sensible that PDO::quote() each escapes and quotes a worth whereas mysql_real_escape() best escapes the value. you'll want to hold this in intellect so that you don’t emerge as with added citation marks in the ultimate query and scratch your head questioning where they came from.
while on occasion which you could gain away with out freeing the outcomes aid with mysql_free_result(), i like to recommend you don’t gain into such slothful habits when the usage of PDO. if you nonetheless occupy a result set from a select question which hasn’t called closeCursor() yet and furthermore you are trying to carry out an INSERT or update on the desk, the trade might furthermore silently fail and again you’ll breathe left scratching your head. It’s stronger to Make a dependancy out of doing issues properly to evade irritating instances later.Digging (a bit) Deeper
What has been covered so far is satisfactory to gain you begun in migrating your Hypertext Preprocessor app from MySQL to PDO as directly and painlessly as possible, however there’s more to PDO than what I’ve proven you. I’d want to additionally highlight a pair of different aspects PDO you may additionally ascertain helpful: organized statements and lumber handling.prepared Statements
A prepared commentary is a illustration of a question as an object. The odds of representing a query as an protest is that extra common sense can breathe linked to it that might otherwise breathe intricate to manage for a flat string representation. as an example, you can specify placeholders in a query that are then bound to variables to your script. here's helpful if you’re working the equal question assorted instances to meet the request however with distinctive parameters. The question handiest has to breathe prepared once, however can furthermore breathe rush time and again with different values because the expense of the variables exchange.<?php // assortment of user assistance to import into the database $clients = ... // specify the query "template" $question = $db->prepare("INSERT INTO users (first_name, last_name, email) VALUES (:fname, :lname, :e mail)"); // bind the placeholder names to particular script variables $question->bindParam(":fname", $firstName); $question->bindParam(":lname", $lastName); $query->bindParam(":email", $e mail); // assign values to the specific variables and execute the question foreach ($users as $u) $firstName = $u["first_name"]; $lastName = $u["last_name"]; $electronic mail = $u["email"]; $question->execute();
The parameters don’t ought to breathe quoted or escaped with organized statements because the underlying driver instantly rates and escapes any bound parameters for you. because of this, many americans want to expend prepared statements to protect against SQL injection vulnerabilities even if the question is simply finished once.Error coping with
which you can specify one of three distinctive error dealing with paradigms with PDO through the expend of PDO::setAttribute() to set the error managing mode.<?Hypertext Preprocessor $db = new PDO($dsn, $user, $passwd); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
The modes are:
despite which mode is set, there is an inner error code which is set and you may determine using the errorCode() and errorInfo() methods of the PDO and PDOStatement objects. These are analogous to mysql_errno() and mysql_error(). errorCode() returns a 5-personality string as defined within the ANSI SQL-92. errorInfo() is commonly greater profitable as it returns an array that includes an error message apart from the 5-personality code.<?php $query = "select * FROM foo the station MALFORMED query"; $outcomes = $db->question($query); $error = $db->errorInfo(); if (!is_null($error)) echo "query failed! " . $error; ...
when you are the usage of the exception mode, a description of what went incorrect is purchasable in the course of the exception object’s getMessage() method.<?Hypertext Preprocessor $query = "opt for * FROM foo where MALFORMED question"; try $outcome = $db->query($question); ... trap (PDOException $e) echo $e->getMessage(); abstract
Now Make sure you occupy the primary odds captious to rise migrating from the older MySQL extension to the more moderen PDO extension. You’ve seen that while most of the time PDO is already purchasable, it’s effortless to deploy if for some rationale it isn’t. You’ve additionally seen how effortless it's to connect to a MySQL database server, problem queries and gain hold of the outcomes. Of course this become simply a practical overview; to breathe taught more about what PDO has to present and how that you would breathe able to entangle abilities of it, I inspire you to study the available documentation at php.net.

Savvy, talented and knowledgeable database professionals are always in demand. Here are some of the best certifications for DBAs, database developers and anyone else working with databases.
During the past three decades, we've seen a lot of database platforms arrive and go, but there's never been any question that database technology can breathe a crucial component for bar nonexistent kinds of applications and computing tasks.
Database certifications may not breathe as sexy or bleeding edge as cloud computing, storage or computer forensics, but the reality is that there has been and will always breathe a exigency for knowledgeable database professionals at bar nonexistent levels and in numerous database-related job roles.
To gain a better grasp of the available database certifications, it's useful to group them around job roles. In part, this reflects the maturity of database technology and its integration into most aspects of commercial, scientific and academic computing. As you read about the various database certification programs, sustain these job roles in mind:
Careful attention to these database job roles highlights two principal technical issues for would-be database professionals to consider. First, a satisfactory common background in relational database management systems, including an understanding of structured query language (SQL), is a basic prerequisite for bar nonexistent database professionals.
Second, although various efforts to standardize database technology exist, much of the whiz-bang capability that databases and database applications deliver arrive from proprietary, vendor-specific technologies. Serious, heavy-duty database skills and learning are tied to specific platforms, including various Oracle products (such as the open source MySQL environment and Oracle itself), Microsoft SQL Server, IBM DB2 and more. That's why most of the certifications relate directly to those very very and enormously approved platforms.
It's principal to note that NoSQL databases – referred to as "not only SQL" and sometimes "nonrelational" – handle many different types of data, such as structured, semi-structured, unstructured and polymorphic. NoSQL databases are increasingly used in spacious data applications, which tend to breathe associated with certifications for data scientists, data mining/warehousing and traffic intelligence. Although there is some natural overlap, for the most part, they cover those certs in their annually updated Best spacious Data Certifications article.
Before you stare at their featured certifications in detail, consider their popularity with employers. The results of an informal job search conducted on several high-traffic job boards reveal which database certifications employers stare for when hiring employees. Though these results vary from day to day (and job board to job board), such numbers carry out provide a useful perspective on database certification demand.Job Board Search Results (in Alphabetical Order by Certification)*

The Oracle Database Certifications page lists divorce tracks for Database Application development (SQL and PL/SQL), MySQL (Database Administration and Developer) and Oracle Database (versions 12c, 12c R2, and 11g, and Oracle Spatial 11g).
MySQL is perhaps the leading open-source relational database management system (RDBMS). Since acquiring Sun Microsystems in 2010 (which had previously acquired MySQL AB), Oracle has rolled out a paid version of MySQL and developed certifications to support the product.
A candidate interested in pursuing an Oracle MySQL certification can choose between MySQL Database Administration or MySQL Developer. The Oracle Certified Professional – MySQL 5.7 Database Administrator (OCP) – credential recognizes professionals who can install, optimize and monitor MySQL Server, configure replication, apply security, and schedule and validate database backups.
The certification requires candidates to pass a single exam (the very exam can breathe taken to upgrade a prior certification). Oracle recommends training and on-the-job experience before taking the exam.Oracle Certified Professional, MySQL 5.7 Database Administrator Facts & Figures
More: Oracle Certifications & Career Paths5. Oracle Database 12c Administrator
Most Oracle DBMS credentials require candidates to attend authorized training classes to qualify for the related exam, but MySQL (and Sun-derived) credentials often carry out not. Oracle certifications furthermore depict a proper ladder, in that it is generally necessary to deserve the associate-level credentials first, professional-level credentials second and master-level credentials third, culminating at the expert level.
Oracle Database 12c R2 is the latest Oracle database version, which includes enhancements to Oracle Database 12c. Currently, Oracle 12c certifications are offered at the associate, professional and master levels.
A Foundations Junior Associate certification (novice level) is furthermore available for Oracle Database 12c, as are three specialist designations – the Implementation Specialist, the Oracle Database Performance and Tuning 2015 Certified Implementation Specialist, and the Oracle real Application Clusters 12c Certified Implementation Specialist. Expert-level credentials that are available involve the Oracle Certified Expert, Oracle Database 12c: RAC and Grid Infrastructure Administrator, Oracle Database 12c Maximum Availability Certified Expert, Oracle Certified Expert, Oracle Database 12c: Data Guard Administrator, the Oracle Certified Expert, and the Oracle Database 12c: Performance Management and Tuning. Oracle offers two 12c R2 certifications: Oracle Database 12c R2 Administration Certified Associate and Professional. Oracle 11g certifications are still offered as well.
Note: Although premium support for Oracle 11g Database ended on Dec. 31, 2014, extended support is until December 2020, so it's probable Oracle Database 11g will remain in expend for the next few years.
We focus on requirements for Oracle 12c and 12c R2 Database certifications. One principal consideration is that Oracle 11g is forward-compatible with Oracle 12c, but Oracle 12c is not backward- compatible with the prior version. Because Oracle 12c is a newer version, IT professionals possessing Oracle 11g certifications should explore upgrades to those credentials.Oracle Database 12c and 12c R2 Administrator Facts & Figures

Exclusive: U.S. police forces are so out of control there’s not even a dependable database on how many times police officers shoot citizens. So, beyond racism and awe of guns, the problem includes fragmentation in law enforcement and gaps in training among the 18,000 police agencies in the 50 states, notes Daniel Lazare.
By Daniel Lazare
America is clearly an outlier when it comes to police brutality. According to The Guardian’s highly useful “Counted” website, U.S. police cancel more people in a typical day than police in England and Wales cancel in an entire year. Where police in Stockton, California, killed three people in the first five months of 2015, police in Iceland, which has roughly the very population, occupy killed just one person since the modern Icelandic republic was founded in 1944.
Where the U.S. saw 97 police shootings in a single month (March 2015), Australia saw 94 over the course of two decades (1992 to 2011). And where police in Finland fired a majestic total of six bullets in 2013, police in Pasco, Washington, pumped nearly three times as many last February into a 35-year-old Mexican immigrant named Antonio Zambrano-Montes whom they accused of threatening them with a rock.
What is the understanding for vast discrepancy? The Black Lives Matter movement blames racism, which is certainly proper as far as it goes, but potentially delusive since its suggests that racism is not a problem in countries like England and Australia, which is definitely not the case.
In a recent analysis, Alternet’s Steven Rosenfeld blamed police reliance on excessive force, an absence of supervision, and a confrontation mentality that leads urban cops to survey their beats as veritable war zones. While this is certainly the case, the logic is more than a bit tautological since bar nonexistent Rosenfeld is maxim is that police are out of control because police are out of control.
The Coalition to Stop Gun Violence blames a “continuing arms race between law enforcement and civilians” that causes cops to survey every suspect as a heavily-armed combatant. But while the police are plainly upping their firepower SWAT teams are often more heavily armed than front-line troops in Afghanistan or Iraq there is no evidence that the medium American is following suit.
Indeed, Gallup reports that the proportion of Americans who impart they occupy a gun at home has declined since the 1960s, while sales of military-style assault weapons occupy so far had a negligible repercussion on crime rates. So there is no evidence that a street-level arms race is underway or that it is causing police to over-react.
Fragmentation of Police Forces
So what is the real understanding that America is off the charts when it comes to police shootings? The most principal explanation is one that almost no one notices: fragmentation.
Britain, for example, has some 50-odd divorce police forces, the Metropolitan Police Service covering greater London, a slew of regional police forces covering the repose of the country, plus a Serious Organized Crime Agency to deal with higher-level offenses.
Germany has a federal police compel plus one police department for each of the sixteen lÃ¤nder, or states, while France, thanks to the Jacobin tradition of centralization, effectively makes carry out with just three police forces in all: the National Police, the National Gendarmerie, and the Municipal Police, only half of whom are armed. Australia meanwhile has eight police forces, New Zealand has just one, while Canada, significantly unusually, has more than 200, including two dozen or more among autochthonous American tribes.
So how many police departments does the United States have? The answer: more than 18,000. This includes three dozen or so at the federal smooth plus a staggering 17,985 at the state and local level everything from state troopers and city patrolmen to campus cops, hospital and housing police, park rangers, and even a special department of zoo police in the town the Brookfield just outside of Chicago.
Where Britain’s police forces are firmly under the control of the Home Office while France’s are under the Ministry of the Interior, moreover, America’s are virtually autonomous. When the Justice Department sent out a survey on the expend of compel in 2013, the answers that came back were so jumbled as to breathe well nigh useless. Some departments sent back information on the expend of guns, while others included reports about punches thrown and the expend of non-lethal devices such as beanbag guns. Others, including such big-city departments as New York, Houston, Baltimore and Detroit, either did not know or refused to say.
A country that doesn’t even know how many times police fire their weapons or under what circumstances is one in which every local department is a law unto itself, a self-contained barony with its own special rules and customs.
“It’s a national embarrassment,” Geoffrey P. Alpert, a University of South Carolina criminology professor, told The New York Times. “Right now, bar nonexistent you know is what gets on YouTube.”
What does a lack of learning occupy to carry out with ultra-high levels of brutality? The respond is simple: absence of learning means an absence of control, which means that local departments behave with relative impunity. If local cops look out of control, it’s because the only controls arrive from local politicians who are often debase and racist and therefore tolerant of such conduct on the Part of the officers they employ.
The Sandra Bland Case
Just what this means became lucid on July 10 when a 28-year-old Chicagoan named Sandra Bland establish herself pulled over by a traffic cop in Waller County, Texas, about 50 miles northwest of Houston. As a graduate of nearby Prairie View A&M, a historically black university, Bland knew how small-town police in rustic Texas operate. So she was angry, upset and prepared for the worst.
“You look very irritated,” Police Officer Brian Encinia told her. To which Bland replied:
“I am, I really am. I was getting out of your way. You were speeding up, tailing me, so I wobble over and you stop me. So, yeah, I am a minute irritated, but that doesn’t stop you from giving me a ticket.”
Bland had a point. When Encinia pulled up nigh behind her, she did the natural thing by stirring over to let him pass. Yet now she establish herself pulled over for a technical infraction, i.e. changing lanes without signaling. Encinia’s aggressive driving triggered the incident in the first place, and now his aggressive conduct was upping the ante.
As the dispute escalated, Bland establish herself thrown to the ground, cuffed and then tossed in jail when she failed to Make bail. Three days later, she was establish departed in her cell.
This is how a feudal knight behaves, not, supposedly, a modern cop in a democratic society. Encinia was suspended, the FBI stepped in, while the local DA launched an investigation to determine if Bland was the victim of a homicide. But this was only after dash cam footage showing Encinia’s confrontational conduct went viral on the Internet and protesters rallied to her cause. Otherwise, the incident would occupy been gone unnoticed.
The killing of Samuel DuBose six days later showed another side of the problem. DuBose was not the victim of an over-aggressive small-town policeman, but of a campus cop from the University of Cincinnati. Normally, the biggest problems campus police physiognomy are rowdy frat-house parties and overflowing parking lots on graduation day.
But in this case, the university, concerned about mounting crime, had entered into an agreement with the city to allow its police to patrol nearby neighborhoods. For a hapless local motorist like DuBose, the upshot was that instead of dealing with a police department accountable in some fashion to the voters of Cincinnati, he now establish himself physiognomy to physiognomy with an officer answerable only to a university board of trustees, bar nonexistent appointees.
Control wound up scrambled, accountability was slashed, while an ill-prepared cop was thrust into a situation for which he was not properly trained. As a consequence, a minor traffic stop ended with DuBose’s death.
Once again, the local DA went into overdrive. County prosecutor Joe Deters slammed Officer Ray Tensing for making a “chicken crap stop,” dismissing his account as “nonsense” and describing DuBose’s shooting as “the most asinine act I’ve ever seen a police officer make.” “This is without question a murder,” he added.
Loss of Accountability
But not only was this furthermore after the fact, but the consequence was to sidestep the issue of why the city had had shunted off policing to a corpse far removed from voters’ control. Responsibility rested not only with Tensing, but with the city officials who entered into such an undemocratic arrangement.
So, once again, it was a case of ineffective controls and a lack of accountability allowing police brutality to flourish. If the Black Lives Matter movement had not been in tall gear by that point, DuBose’s death would almost certainly occupy been overlooked as well. But while emotions ran high, awareness of the basic structural issues at hand was nil.
This bent contradiction outrage on one hand and utter passivity with esteem to the larger political issues on the other begs two questions: why has fragmentation become so massive, and why is it bar nonexistent but invisible?
The first is easy. The problem goes back to the deal that America’s so-called Framers struck in Philadelphia in 1787 in which they not only divided power among three branches of government, but furthermore between the federal government and the states. While the former wound up with the capacity to tax, borrow, regulate commerce, and coin money, the latter gained an bar nonexistent but unchallengeable monopoly on local governance.
Things occupy gotten a bit more complicated since then thanks to the civil liberties movement, the New Deal, the civil rights revolution, and other such events. But to a remarkable degree, the original division of responsibility still holds. While the feds intervene from time to time in urban policy, they carry out so obliquely while local prerogatives remain sacrosanct.
Much as Congress carved states out of the western territories, the states gained carte blanche not only to create as many police departments as they wish, but to carve out an endless number of municipalities and school districts as well, not to mention water and sewer boards, mosquito control commissions, and other exotic flora and fauna.
The upshot is not only 18,000 police departments but more than 90,000 local governments in all, bar nonexistent autonomous, self-governing, and endlessly envious of their rights and prerogatives.
“[I]f there was a preponderant ‘originalist’ notion of how the nation’s governance should work,” notes a prominent investigative reporter, “it was pragmatism; it was pulling together to gain done what needed to breathe done” (Robert Parry, America’s Stolen Narrative, pp. 32-33).
But leaving aside the fact that pragmatism is far from a simple concept the Stanford Encyclopedia of Philosophy entry on the subject runs to more than 10,000 words it is difficult to survey how such an rococo arrangement can breathe described as pragmatic when there is no way to determine whether it is still working or what “working” in this context even means.
Does San Diego County (population 3.1 million), to cite just one example, really need 65 divorce fire departments? Does New Jersey (population 8.7 million) really exigency 565 municipalities and 591 school districts? Couldn’t the very tasks breathe accomplished more cheaply and efficiently if local government was consolidated?
The very goes for the police. Does America really exigency 18,000 police departments? Couldn’t the very tasks breathe conducted more efficiently and fairly if the departments were consolidated and placed firmly under federal control?
Fear of Centralism
Conservatives will reply that any such nationalization would breathe tyrannical and that local prerogatives like these are the essence of American liberty. But just as liberty for the pike means death for the minnow, liberty for local pols in Waller County meant the contrary for Sandra Bland.
Americans went to war in 1776 because the British were “erect[ing] a army of New Offices, and sen[ding] hither swarms of Officers to harass their people and devour out their substance.” But with their 90,000 local governments, Americans occupy wound up saddling themselves with more local officials than George III could ever occupy imagined.
It’s a system crying for rationalization and reform. But this leads to the second question: how is it that no one notices? Where other countries fiddle with municipal governance as a matter of routine, abolishing some jurisdictions, creating others, and constantly re-adjusting powers and responsibilities, the very understanding remains unthinkable in the U.S.
So what is the reason? The respond has to carry out with what one might muster the unlit side of pragmatism. If American governance rests on the dual principles of practicality and workability, then it follows that there is no point discussing a reform if it is not remotely in the cards. Indeed, there’s no point thinking about the problem in the first station or even noticing that it exists.
The absurdity of 18,000 autonomous police departments should breathe obvious to all, yet, for even the most ardent civil-rights campaigner, it disappears from view.
So carry out other bent aspects of the U.S. constitutional system a Senate that gives the very number of votes to Wyoming (population 576,000) that it does to a multi-racial giant like California (population 38 million); an electoral college that triples the weight of unavoidable lily-white “rotten boroughs” (as under-populated electoral districts were known in Eighteenth-Century England), or a two-thirds/three-fourths amending clause that, thanks to growing population discrepancies, allows 13 largely rustic states representing as minute as 4.1 percent of the population to veto any constitutional change sought by the remaining 95.9.
Rather than the elephants in the sitting scope that no one wishes to discuss, these are elephants that no one even notices.
Which brings us back to race. Although civil libertarians celebrate America’s 228-year-old constitutional system on the grounds that it locks in the Bill of Rights, the consequences are not remotely democratic. To the contrary, the consequence is not only to fragment power from above, but, more importantly, to muffle and disperse democratic political power from below by placing countless obstacles in its path.
As a result, racism is allowed to fester in countless nooks and crannies in America’s over-complicated political structure. The disease thus spreads, infecting one organ after another.
For protesters, the consequence is a inquisitive coalesce of enraged and complacency. Young people entangle to the streets in response to the latest outrage. They march and chant as they challenge the powers-that-be. But then the fury wanes, and everyone goes back home. With gyroscopic efficiency, the system rights itself and fragmentation continues unabated.
If you want a picture of the future, to paraphrase Orwell, imagine an endless succession of Sandra Blands hanging in their cell forever.
