How to Build an App That’s as Addictive as Coffee

September 22, 2015

Coffee and running are addictive in their own unique ways. Each provides a buzz that keeps people coming back for more. In kind, Runkeeper and Starbucks don’t just help people feed their addictions; these apps are as habit-forming as the behaviors they supplement.

Due to its goal-based reward system, Runkeeper’s users don’t feel like their run “counts” unless it’s tracked within the app. And due to Starbucks’ loyalty-based reward system, customers feel compelled to purchase with the app because they don’t want to miss out on the rewards and VIP status that come with being a regular customer.

When apps aren’t addictive, users open them one time, explore for a few minutes, and promptly delete them from their devices. Depending on your industry,...read more

Darrin Patrick’s Death, His Love for Pastors, and How We Need One Another

Darrin’s death is not the last word on his life. His love for pastors—and his concern for their mental health and thriving—can be part of our response today.

Darrin Patrick has died.

Darrin is probably best known for planting The Journey Church in St. Louis in 2002, eventually growing to six locations. He was a husband, father, speaker, and author.

Darrin and his spiritual mentor Greg Surratt led the Pastor's Collective podcast and he was serving as a teaching pastor at Seacoast Church.

But, most importantly, Darrin was married to Amie and they have four children.

Darrin’s Journey and Focus

Darrin was very open about his journey—and specifically asked me to help share his story a little over a year ago. His story of leaving the Journey is painful and messy, but he wanted people to know about it.

He wanted people to learn from his pain.

Darrin died from a “self-inflicted gunshot wound.” I know that has caused some people to want more details—to use language that is more precise and to provide added details. And, as you can tell from the statement, the situation is confusing. Seacoast Church shared, ““Darrin was target shooting with a friend at the time of his death. An official cause of death has not been released but it appears to be a self-inflicted gunshot wound. No foul play is suspected.”

Thus, it is important to let families communicate the way they are comfortable. Families grieve in complex ways—and right now, they owe nothing to the rest of us. We just owe them our prayers.

The family is grieving and I am respecting their grief and their communication choices.

And, from there, I am going to take Darrin’s admonition from a year ago and fast forward it until now—hoping that even this moment might be a catalyst for pastors to get help that Darrin always wanted them to get.

Darrin and I talked recently and his last ...

checkCIF validation ALERTS: what they mean and how to respond

Authors of a paper that includes a new crystal-structure determination are expected to not only report the structural results of inter­est and their inter­pretation, but are also expected to archive in computer-readable CIF format the experimental data on which the crystal-structure analysis is based. Additionally, an IUCr/checkCIF validation report will be required for the review of a submitted paper. Such a validation report, automatically created from the deposited CIF file, lists as ALERTS not only potential errors or unusual findings, but also suggestions for improvement along with inter­esting information on the structure at hand. Major ALERTS for issues are expected to have been acted on already before the submission for publication or discussed in the associated paper and/or commented on in the CIF file. In addition, referees, readers and users of the data should be able to make their own judgment and inter­pretation of the underlying experimental data or perform their own calculations with the archived data. All the above is consistent with the FAIR (findable, accessible, inter­operable, and reusable) initiative [Helliwell (2019). Struct. Dyn. 6, 05430]. Validation can also be helpful for less experienced authors in pointing to and avoiding of crystal-structure determination and inter­pretation pitfalls. The IUCr web-based checkCIF server provides such a validation report, based on data uploaded in CIF format. Alternatively, a locally installable checkCIF version is available to be used iteratively during the structure-determination process. ALERTS come mostly as short single-line messages. There is also a short explanation of the ALERTS available through the IUCr web server or with the locally installed PLATON/checkCIF version. This paper provides additional background information on the checkCIF procedure and additional details for a number of ALERTS along with options for how to act on them.

Synthesis and crystal structure of catena-poly[[bis[(2,2';6',2''-terpyridine)­manganese(II)]-μ4-penta­thio­dianti­monato] tetra­hydrate] showing a 1D MnSbS network

The asymmetric unit of the title compound, {[Mn2Sb2S5(C15H11N3)2]·4H2O}n, consists of two crystallographically independent MnII ions, two unique terpyridine ligands, one [Sb2S5]4− anion and four solvent water mol­ecules, all of which are located in general positions. The [Sb2S5]4− anion consists of two SbS3 units that share common corners. Each of the MnII ions is fivefold coordinated by two symmetry-related S atoms of [Sb2S5]4− anions and three N atoms of a terpyridine ligand within an irregular coordination. Each two anions are linked by two [Mn(terpyridine)]2+ cations into chains along the c-axis direction that consist of eight-membered Mn2Sb2S4 rings. These chains are further connected into a three-dimensional network by inter­molecular O—H⋯O and O—H⋯S hydrogen bonds. The crystal investigated was twinned and therefore, a twin refinement using data in HKLF-5 [Sheldrick (2015). Acta Cryst. C71, 3–8] format was performed.

How far are we from automatic crystal structure solution via molecular-replacement techniques?

Although the success of molecular-replacement techniques requires the solution of a six-dimensional problem, this is often subdivided into two three-dimensional problems. REMO09 is one of the programs which have adopted this approach. It has been revisited in the light of a new probabilistic approach which is able to directly derive conditional distribution functions without passing through a previous calculation of the joint probability distributions. The conditional distributions take into account various types of prior information: in the rotation step the prior information may concern a non-oriented model molecule alone or together with one or more located model molecules. The formulae thus obtained are used to derive figures of merit for recognizing the correct orientation in the rotation step and the correct location in the translation step. The phases obtained by this new version of REMO09 are used as a starting point for a pipeline which in its first step extends and refines the molecular-replacement phases, and in its second step creates the final electron-density map which is automatically interpreted by CAB, an automatic model-building program for proteins and DNA/RNA structures.
