In the moral realm there may be 7 deadly sins, but scalability maven Sean Hull has come up Five More Things Deadly to Scalability that when added to his earlier 5 Things That are Toxic to Scalability, make for a numerologically satisfying 10 sins again scalability:

  1. Slow Disk I/O – RAID 5 – Multi-tenant EBS. Use RAID 10, it provides  good protection along with good read and write performance. The design of RAID 5 means poor performance and long repair times on failure. On AWS consider Provisioned IOPS as a way around IO bottlenecks.
  2. Using the database for Queuing. The database may seem like the perfect place to keep work queues, but under load locking and scanning overhead kills performance. Use specialized products like RabbitMQ and SQS to remove this bottleneck.
  3. Using Database for full-text searching. Search seems like another perfect database feature. At scale search doesn't perform well. Use specialized technologies like Solr or Sphinx.
  4. Insufficient Caching at all layers. Use memcache between your application and the database. Use a page like cache like Varnish between users and your webserver. Select proper caching options for your html assets.
  5. Too much technical debt. Rewrite problem code instead of continually paying a implementation tax for poorly written code. In the long run it pays off.
  6. Object Relational Mappers. Create complex queries that hard to optimize and tweak.
  7. Synchronous, Serial, Coupled or Locking Processes. Locks are like stop signs, traffic circles keep the traffic flowing. Row level locking is better than table level locking. Use async replication. Use eventual consistency for clusters.
  8. One Copy of Your Database. A single database server is a choke point. Create parallel databases and let a driver select between them.
  9. Having No Metrics. Visualize what's happening to your system using one of the many monitoring packages.
  10. Lack of Feature Flags. Be able to turn off features via a flag so when a spike hits features can be turned off to reduce load.

At the heart of the Mennonite religion, you’ll find an unwavering commitment to nonresistance that has endured five centuries of oppression and violent atrocities. This work is a photographic ode to an endless journey that my Mennonite ancestors undertook in the name of peace.

Right from their origins in the 16th and 17th centuries, Mennonites in the Netherlands were hunted down by the Catholic Church and publicly tortured to death because of their Christian beliefs. This prompted the Mennonites to migrate to Poland, where they remained for a century until the state began to force them into military service. In the late 18th century, the Mennonites chose to migrate again — this time to Ukraine and Russia.

On a bitterly cold winter night, in the midst of the Russian Revolution, Bolshevik soldiers arrived at my family’s doorstep. They forced 48 Mennonite men to walk from house to house at gunpoint using them as human shields as they stormed the non-Mennonite homes; my great grandfather was one of three survivors from that group. During the revolution, entire Mennonite villages were wiped off the map in nighttime massacres that saw men, women and children struck down by Bolshevik soldiers on horseback. Those who were able to escape with their lives would return to their villages the following day to bury their neighbours and families in unmarked mass graves before beginning new lives as refugees. Throughout their history, the Mennonites have been repeatedly faced with the same decision: Take up arms and abandon your faith, leave your home behind and give up everything you have worked for in your life, or die where you stand.

In 2012, I decided to re-trace the refugee migrations of the Mennonites to witness the places where they lived and died. I followed their historical journey through The Netherlands, Germany, Poland and Ukraine, photographing the communities, farmland, execution sites and mass graves that had been left behind. The path on which I traveled emulated the nomadic history of the Mennonites, while I searched for a feeling of familiarity and a connection to the former homes of my distant relatives. In most places along the migration route, the lingering presence of the Mennonites was little more than a collection of memories; a pockmarked gravestone; the mossy foundations of a farmhouse; a group of blurry faces, locked away in a history textbook. I found myself sifting through peaceful cow pastures and rural villages, seeking the ghosts of unimaginable heartbreak and tragedy.

The process of carrying out this work took an emotional toll, but the experience taught me to admire the Mennonites for their immense personal sacrifices. The Mennonites gave up community, prosperity and even faced death because they believed in the statement of nonresistance. I feel that if the places in these photographs could speak, they would tell us that hostilities brought against pacifist peoples are more than an injustice; they are an attack upon the hope for peace within our world.

Spanish photographer Ricardo Cases came to Maryland and spent three days documenting the worship at two evangélico churches for TIME: La Roca de la Eternidad, Rock of Eternity Church, and Iglesia Cuadrangular el Calvario, Calvary Foursquare Church (to read the new TIME cover story, available to subscribers, click here). If you visit either, you may feel more like you are at religious revival in Latin America than at a Sunday service just a half hour from Washington, D.C. But these churches are not exceptions. Born-again, Latino Protestants are on the rise in the United States. More than 40% of Hispanic evangelicals in the United States converted from Catholicism, according to the Pew Forum on Religion and Public Life.

Evangélico worship styles differ greatly from the traditional Catholic mass. There are rock bands, streamers, tambourines, flags, dancing, and loud praying. Sometimes there is even prophesying or fainting in God’s presence. It was a new experience for Cases. “Although I am not religious, my education is Catholic, and I only know the Catholic Church ceremonies in which everything happens in a more linear way, less expressive and more boring,” Cases says.

His images capture the blend of intensity, isolation, and fiesta that is often part of the evangélico experience. Both La Roca and El Calvario are more than just venues for Sunday worship. They have become homes for people far from their homeland, and worship services are sacred yet familial. “For me, it was a surprise, the great contrast between the moments before the service, and the service itself,” Cases reflects. “Attendees moved from a festive mood to a dramatic one in minutes.”

The shoot itself was a reminder that evangélico worship in the United States is inextricably linked to the immigrant experience. One moment said it all. When Cases was playing with the little kids at one of the El Calvario services, they wanted to know his name. He teased them and replied: “Obama.” They all started yelling, Obama! Obama! Then one little boy, maybe six or seven years old, asked in broken in English: “Hey! Obama! Can you give me a resident?”

Ricardo Cases documented the Republican presidential primary race in Florida for TIME in 2012. His recent book Paloma al Aire documents the tradition of pigeon racing.
