the language provides the framework for using the patterns as a program to create form.  But he aims for semantics, allegory, and poetics, as well as the aspects of language that generate feelings, emotions, a sense of order — all of which extend beyond the structural, topological and syntactic aspects of his program.

=> 箭头函数的匿名性是 => 的阿喀琉斯之踵。这让我不能遵守刚刚所说的命名原则了：阅读困难，调试困难，无法自我引用。

顺便说一句，匿名的意思是什么？具体来说，函数具有一个 name 的属性，用于保存函数在语法上设定名称的字符串值，例如 "helloMyNameIs" 或 "FunctionExpr"。 这个name 属性特别用于 JS 环境的控制台或开发工具。当我们在堆栈轨迹中追踪（通常来自异常）时，这个属性可以列出该函数。

我们将在本书的后续中大量使用闭包。如果抛开整个编程来说，它可能是所有函数式编程中最重要的基础。希望你能用得舒服！

在所有编程，尤其是函数式编程中，最强大的就是：当一个函数内部存在另一个函数的作用域时，对当前函数进行操作。当内部函数从外部函数引用变量，这被称作闭包。

将其他函数视为值的函数是高阶函数的定义。函数式编程者们应该学会这样写！

这个隐式函数输出在函数式编程中有一个特殊的名称：副作用。当然，没有副作用的函数也有一个特殊的名称：纯函数。我们将在以后的章节讨论这些，但关键是我们应该喜欢纯函数，并且要尽可能地避免副作用。

但是，改变一个外部作用域的变量，就像我们在 foo(..) 中所做的赋值 y 一样，只是实现隐式输出的一种方式。一个更微妙的例子是通过引用对非局部值进行更改。

我不是说，你只能有一个 return，或你不应该提早 return，我只是认为在定义函数时，最好不要用 return 来实现流控制，这样会创造更多的隐含意义。尝试找出最明确的表达逻辑的方式，这往往是最好的办法。

提示： 在这里我十分建议你花一点时间来思考：是否需要避免函数有可重构的多个输出？或许将这个函数分为两个或更多个更小的单用途函数。有时会需要这么做，有时可能不需要，但你应该至少考虑一下。

function foo() { var retValue1 = 11; var retValue2 = 31; return [ retValue1, retValue2 ]; } var [ x, y ] = foo(); console.log( x + y ); // 42

如果你没有 return 值，或者你使用 return;，那么则会隐式地返回 undefined 值。 如果想要尽可能靠近函数式编程的定义：使用函数而非程序，那么我们的函数必须永远有返回值。这也意味着他们必须明确地 return 一个值，通常这个值也不是 undefined。

通过不同的输入值让一个函数重载拥有不同的行为的技巧叫做特定多态（ad hoc polymorphism）。

程序员这样定义函数的原因之一是，更容易通过同一个函数来重载不同的功能。最广为人知的例子就是 jQuery 提供的 $(..)。"$" 函数大约有十几种不同的功能 —— 从 DOM 元素查找，到 DOM 元素创建，到等待 “DOMContentLoaded” 事件后，执行一个函数，这些都取决于你传递给它的参数。

回想一下，术语 Arity 是指期望函数接收多少个参数。Arity 为 1 的函数也被称为一元函数。在函数式编程中，我们希望我们的函数在任何的情况下是一元的，有时我们甚至会使用各种技巧来将高 Arity 的函数都转换为一元的形式。

只要可能，无论我们的语言和我们的库或框架允许我们达到什么程度，我们都应该尽可能使用声明性的和自解释的代码。

数组解构

无论采取什么行为， ... 都会让实参数组更容易操作。那些我们使用实参数组 slice(..)，concat(..) 和 apply(..) 的日子已经过去了。

牺牲向后的兼容性

foo(..) 期望三个实参，因为它声明了三个形参。这里有一个特殊的术语：Arity。Arity 指的是一个函数声明的形参数量。 foo(..) 的 Arity 是 3。

最好的代码是可读性高的代码，因为它在正确的（理想主义）和必然的（正确的）之间寻求到了恰到好处的平衡。

我们将在下一章更深入的讨论这个问题。但是你可能写过一些命令式的代码，像 if 语句和 for 循环这样的语句。这些语句旨在精确地指导计算机如何完成一件事情。声明式代码，以及我们努力遵循函数式编程原则所写出的代码，更专注于描述最终的结果。

你知道研究过这个话题的专家给出了怎样的数据吗？我们在维护代码过程中 70％ 的时间花在了阅读和理解代码上。 也难怪全球程序员每天的平均代码行数是 5 行。我们一天花七个半小时用来读代码，然后找出这 5 行代码应该写在哪里。

根据以往经验你可能知道，有时候花很多时间“编程”其实只是读现有的代码。我们的大部分时间其实都是在维护别人的代码（或自己的老代码），只有少部分时间是在敲新代码。

信任是什么意思？信任是指你通过读代码，不仅是跑代码，就能理解这段代码能干什么事，而不只是停留在它可能是干什么的层面。

BOULDER COUNTY IMPACT:Building and Sustaining Policy, Practice and Improvement Standardsfor a Multi-Program, Multi-System Collaborative

there is a disconnect between the long period of evolution that honed our humanity and the short period of rapid technology change we are facing.

Unlike many developed countries, the United States lacks a national curriculum or teacher-training standards. Local policies change constantly, as governors, school boards, mayors and superintendents flow in and out of jobs.

Her curriculum, “Units of Study,” is built on a vision of children as natural readers, and it has been wildly popular and profitable. She estimates that a quarter of the country’s 67,000 elementary schools use it. At Columbia University’s Teachers College, she and her team have trained hundreds of thousands of educators.

Colorado’s vision is that all children, youth, parents or kin caregivers with these risk factors will be eligible for Title IV-E prevention services—both those who are involved in the child welfare system and those who have not been the subject of a child maltreatment report but share characteristics that deem them at serious risk of out-of-home placement.

Reunification, adoption or guardianship arrangements that are at risk of disruption

the existing system cannot just be modified; rather, a fundamental shift in service delivery and support to families must occur.

The IMPACT organization.

I would have preferred a “Yes/No” option for this question. I believe that Boulder County’s prevention services are better than most districts and we can do so much better at the same time. The IMPACT partnership in Boulder County should be a state and national model. Money diverted from savings by not committing clients is key to providing more services in the community. Many other districts struggle with prevention due to funding and there seems to be a gap in how this is accomplished. Providers are struggling to stay open and are constantly dealing with hardships due to funding. Great therapist and support workers often leave organizations that serve this population due to low pay. The key to making the Family First initiative a success is creating and maintaining a robust, well-funded system of care in communities. A system of care that incentivizes front line workers. These service providers are currently under funded and the work is difficult, which is a recipe for poor service delivery.

HOUSE BILL 11-1196

The Core Services Program was established in 1994 to provide strength-based resources and support to families when children and youth are at imminent risk of out-of-home placement, in need of services to return home or to maintain a placement in the least restrictive setting possible.

Core Services Program goals Focus on family strengths by directing intensive services that support and strengthen the family and/or protect the child/youth Prevent out-of-home placement of the child/youth Return children/youth in placement to their own home or unite children/youth with their permanent families Provide services that protect the child/youth

recognition that children/youth need a safe and stable family and that separating children/youth from their families and communities removes them from natural supports and often causes trauma, leaving lasting negative effects.

If you are appointed after a petition for removal has been filed, ask whether prevention services were offered before removal—including services for the parent, kinship caregiver, or child. If appropriate for your client’s goals, advocate for prevention services as an alternative to removal

“Hard Services”: the purchase of services or distribution of cash payments for the following:- housing funds, including rent, repairs, utilities, or rent deposits- food or money for food- clothing- transportation to include fares, auto repair, auto fuel, auto insurance or bus pass- uncovered medical or dental expenses- appliances, furniture- emergency shelter- employment related expenses, such as tools or dues

County departments must make all of the Core services, except for county designed services, available toany client who meets the criteria for the service

Programs should be based on well-articulated theories.

Programs should have a primary focus on a population served by the child welfare agency.

however, in describing the models on which their program is based, administrators tend to focus on service delivery characteristics (most notably caseload size and service duration) rather than on the theoretical underpinnings of the service delivery model.

service programs designed to provide follow-up care to families to whom a child has been returned

In 1993, Congress passed legislation establishing title IV, part B-2 of the Social Security Act, creating funding for family preservation and family support programs.

7.301.21 Family Services Plan Timing Requirements [Eff. 09/01/2007]The Family Service Plan document must be completed:A. Within sixty (60) calendar days of opening an assessment in the automated case managementsystem for children in their own homes, including Core Services program cases in which thechildren are not in out-of-home placement. There may be one Family Services Plan for the familyin these cases.

7.303.15 Service Time FramesA. Services may be provided for up to eighteen (18) months

“Diagnostic and Treatment Planning Services”: various evaluations of the child and family tofacilitate the development of the Family Services Plan and the move of the child to a permanentplacement.

Core Services Programs may include any of the following elements of service:

Family preservation is the foundation The Core Services Program is based on a foundation of research and practice in family preservation. Family preservation services are generally short-term, family-based services designed to support families in crisis by improving parenting and family functioning while keeping children/youth safe.

Family preservation services There are 10 designated types of family preservation services, listed below, and this array of services constitutes the Core Services Program. Aftercare Services: Any of the Core Services provided to prepare a child for reunification with his/her family or other permanent placement and to prevent future out-of-home placement of the child. County Designed Services: An optional service tailored by the specific county in meeting the needs of families and children in the community in order to prevent the out-of-home placement of children or facilitate reunification or another form of permanence. County designed services encompass components of the menu of Core Services, yet are structured in their delivery and tracked uniquely to gain detailed data on evidenced-based programs, as well as programs that are providing positive outcomes in communities around the state. Day Treatment: Comprehensive, highly structured services that provide education to children and therapy to children and their families. Home-Based Intervention: Services provided primarily in the home of the client and include a variety of services, which can include therapeutic services, concrete services, collateral services and crisis intervention directed to meet the needs of the child and family. See Section 7.303.14 for service elements of therapeutic, concrete, collateral, and crisis intervention. Intensive Family Therapy: Therapeutic intervention typically with all family members to improve family communication, functioning, and relationships. Life Skills: Services provided primarily in the home that teach household management, effectively accessing community resources, parenting techniques, and family conflict management. Mental Health Services: Diagnostic and/or therapeutic services to assist in the development of the family services plan and to assess and/or improve family communication, functioning, and relationships. Sexual Abuse Treatment: Therapeutic intervention designed to address issues and behaviors related to sexual abuse victimization, sexual dysfunction, sexual abuse perpetration, and to prevent further sexual abuse and victimization. Special Economic Assistance: Emergency financial assistance of not more than $2,000 per family per year in the form of cash and/or vendor payment to purchase hard services. See Section 7.303.14 for service elements of hard services. Substance Abuse Treatment Services: Diagnostic and/or therapeutic services to assist in the development of the family service plan, to assess and/or improve family communication, functioning and relationships, and to prevent further abuse of drugs or alcohol.

return to families from which they have been removed

Family Preservation Services -- services for children and families designed to help families (including adoptive and extended families) at risk or in crisis, including:

services designed to improve parenting skills (by reinforcing parents' confidence in their strengths, and helping them to identify where improvement is needed and to obtain assistance in improving those skills) with respect to matters such as child development, family budgeting, coping with stress, health and nutrition.

preplacement prevention services programs, such as intensive family preservation programs, designed to help children at risk of foster care placement remain with their families;

Criterion #2: Programs should be based on well-articulated theories

The Family First Transition Act temporarily suspends the requirement that at least 50% of title IV-E prevention services expenditures be for “well-supported” practice for two fiscals years

The Family First Prevention Services Act (Family First) creates an expanded entitlement/50% reimbursement of federal funds to provide services to keep children and youth safely with their families.

Supported and well-supported services in Colorado’s prevention plan should be paid for using the Core Services Program allocation, Child Welfare Services Block, or State General Fund.

RationaleAs evidence-based research becomes the norm in child welfare practice, countiesare more interested than ever in evaluating the effectiveness of services and placementsprovided to children and families in the system.

Formally referred to as family preservation services (FPS), the Colorado CoreServices Program is based on “assistance that focuses on family strengths and includesservices that empower a family by providing alternative problem-solving techniques,child-rearing practices, and responses to living situations creating stress for the family”(C.R.S. 26-5.5-103). The Core Services Program also includes the provision of resources(e.g., special economic assistance) to serve as support systems for children and families.

RationaleAs evidence-based research becomes the norm in child welfare practice, countiesare more interested than ever in evaluating the effectiveness of services and placementsprovided to children and families in the system.

erefore, toassist states in providing services designed to support families and helpkeep them together, the Congress enacted legislation as part of theOmnibus Budget Reconciliation Act of 1993 ( OBRA 1993) that authorized$930 million in federal funds to states over a 5-year period for familypreservation and support (FPS) services. Family preservation servicestypically target families already in crisis whose children would otherwisebe removed from home. Family support services are community-basedactivities intended to prevent the kinds of crises that family preservationservices are aimed at alleviating. To receive federal funds for theseservices, each state had to submit a grant application in 1994 and a 5-yearplan in 1995 that set quantifiable goals and methods for measuringoutcomes

26-5.3-104. Emergency assistance for families with children at imminent risk of being placed out of the home.(1) The executive director of the state department is hereby authorized to include in the state temporary assistance for needy families plan the establishment and implementation of an emergency assistance program for families with children at imminent risk of being placed out of the home. The purpose of the program shall be to meet the needs of the family in crisis due to the imminent risk of out-of-home placement by providing emergency assistance in the form of intake, assessment, counseling, treatment, and other family preservation services that meet the needs of the family which are attributable to the emergency or crisis situation.

I like to organize all the state in a program so that it's reachable from some root pointer. This makes it easy for the reader to understand all the resources allocated by the program by just following the tree of types. It also makes it easy to find any piece of state from within a debugger, or to write little debugging helpers that eg check global invariants or print queue lengths.

This is critical since many optimizations are accomplished by violating (hopefully safely) module boundaries; it is disastrous to incorporate optimizations into the main body of code. The separation allows the optimizations to be checked against the meanings.

It's typically taken for granted that better performance must require higher complexity. But I've often had the experience that making some component of a system faster allows the system as a whole to be simpler

The latest SQLite 3.8.7 alpha version is 50% faster than the 3.7.17 release from 16 months ago. [...] This is 50% faster at the low-level grunt work of moving bits on and off disk and search b-trees. We have achieved this by incorporating hundreds of micro-optimizations. Each micro-optimization might improve the performance by as little as 0.05%. If we get one that improves performance by 0.25%, that is considered a huge win. Each of these optimizations is unmeasurable on a real-world system (we have to use cachegrind to get repeatable run-times) but if you do enough of them, they add up.

The Business Strategy stems from a detailed strategic planning process. However, the question we want to answer in this article is whether we can execute multiple strategies side by side while they do not interfere with each other. We compare multiple strategies for business, information provision and IT and focus on Strategic planning.
