Vehicle Destination Charges - New Car Business Destination Fees - Kelley Blue Book

Have you ever wondered what you're paying for when you buy a new car and the paperwork lists tax, license and destination charge? What is the destination charge all about? Well, if you've seen the trucks carrying cars on the highways or freight trains stacked with new vehicles, you are basically witnessing the service your destination fees pay. The fee is usually in the neighborhood of $400 — $800 per vehicle and no amount of negotiating will make it go away.

Logic would tell you that if you lived near a port or a particular automotive assembly plant, you could potentially pay less for the destination fees — not so. The destination charge is calculated by each manufacturer based on something called an "equalized delivery." In other words, they factor the cost of shipping all vehicles in the line and "equalize" the cost so the fee is "equal" for all car-buyers.

How to Get the Best Car Loan | New Car Buying - Consumer Reports

Some consumers will spend days making sure they get the lowest price on a vehicle, yet they won't bother to shop for the best auto loan. If you don't have financing in place when you visit the dealership to buy, you're leaving yourself vulnerable to whatever terms the dealer offers, which may have a much higher interest rate than you could get elsewhere. And dealers often mark up the interest rate of a loan over what you actually qualify for, which can cost you hundreds of dollars extra.

5 Car Loan Mistakes That Cost You Money | Bankrate.com

4. Rolling negative equity forward. "Upside down" is the term used to describe owing more on your car than it is worth. The difference is "negative equity." When a dealer tells an upside-down consumer that he can fold that negative equity into the car financing of the next deal, he means that he will add it to the purchase price of the new car.

SSH Port forwarding through multiple hops [.ssh/config]

Anybody that have to work with lab at work knows the pain of connecting to them. Usually labs don't have direct connectivity to the "regular" network and to connect to them involves a series of jumps though different machines. Just SSH connectivity is painful in those scenarios let alone port forwarding. Fortunately you can setup your ~/.ssh/config in such a way that will automate most of it, if not all.

GitHub - tsantalis/JDeodorant: JDeodorant

JDeodorant is an Eclipse plug-in that detects design problems in Java software, known as code smells, and recommends appropriate refactorings to resolve them.

For the moment, the tool supports five code smells, namely Feature Envy, Type/State Checking, Long Method, God Class and Duplicated Code.

Feature Envy problems can be resolved by appropriate Move Method refactorings.
Type Checking problems can be resolved by appropriate Replace Conditional with Polymorphism refactorings.
State Checking problems can be resolved by appropriate Replace Type code with State/Strategy refactorings.
Long Method problems can be resolved by appropriate Extract Method refactorings.
God Class problems can be resolved by appropriate Extract Class refactorings.
Duplicated Code problems can be resolved by appropriate Extract Clone refactorings.

Automating Code Reviews - Software People Inspiring

This comes up quite often these days, so I thought I'd scribble my thoughts down, for posterity if nothing else.

I increasingly come across dev teams who have adopted a policy where every check-in needs to be reviewed before it can be accepted. In many cases, this has created a bottleneck while developers waiting to get a green build are stuck on the availability of their peers to do the reviewing.

Imagine, every time you want to check your code in, you have to wait for a tester to put your code through its paces. We knew that was a major bottleneck, so we started automating our tests. If the tester would normally check to see what happens if a customer cancels an order, we would write a unit test for the cancel() function of an order.

It's really not much different for code inspections. If a reviewer would normally check that no classes are too big (say, having more than 200 lines of code), we could write a bit of code to inspect every class and report any that exceed our limit.

A pretty comprehensive code inspection could cover a large amount of code, checking for a whole range of issues, in a tiny fraction of the time it takes a human. More importantly, those checks could be run any time. No need to wait for Jenny to get off the phone, or Rajesh to come back from lunch. You'd no longer be blocked.

This, of course, takes some considerable investment early on to develop the right suite of automated quality checks. But I see more and more teams struggling to maintain the pace of development and high code quality, and such an investment really pays for itself many times over, even on relatively short timescales.

It's for this reason that I'm going to be giving Continuous Inspection a big push in 2018. I think most teams should seriously consider it.

[JavaSpecialists 165] - Starvation with ReadWriteLocks

Welcome to the 165th issue of The Java(tm) Specialists' Newsletter, sent to you from Wall Street, New York City. New York has to date been the most expensive city that I have visited. Not that prices are particularly high in comparison to Crete, but you can purchase almost anything, twenty four hours a day! Usually when I go to New York, my bank sends me urgent emails confirming that I really am spending all that money on my credit card. In contrast, back home in Crete, items are often double the New York price, but there is very little temptation to spend.

Java Memory Leaks: Solutions, Tools, Tutorials & More

Memory management is Java's strongest suit, and one of the many reasons why developers choose Java over other platforms and programming languages. On paper, you create objects and Java would deploy its Garbage Collector to allocate and free up memory. But that's not to say Java is flawless; in real life, memory leaks do happen, and it happens a lot in Java applications. We put together this guide to arm you with the know-how to detect, avoid, and fix memory leaks in Java.

Getting test coverage reports for integration test – George's Techblog

I'm a vociferous supporter of integration tests with an embedded servlet container and in this post I'll show how to get test coverage for the classes touched in those integration tests.

All test coverage gauging tools I know instrument code under test either at build time or run time through Java agents. Because the code under test runs in the servlet container's class loader, it may either not be properly instrumented or evade recording of its execution.

Java Holiday Calendar 2016 (Day 15): Don't Optimize Now! - DZone Java

The JVM is also using a scheme called Code Flattening , which means that it is able to "roll up" method calls and consider the code as a larger flow of operations. This way, it is able to determine the possible paths the program can take and consider these paths individually and optimize them. For example, identical range checking that takes place in several methods that call each other can be eliminated. Another example is that dead paths (e.g. where an "if"-branch is using a constant expression) can be eliminated altogether.

Another means of optimization is Escape Analysis, which is used to determine if an object is visible outside a certain scope. If not, the object can be allocated on the stack rather than on the heap, making the program run much faster.

Minborg's Java Pot

In my previous post, I wrote about how to use Transactions in an easy way using Speedment where we updated two bank accounts atomically. As you all might know, transactions are a way of combining a number of database operation into a single operation that is atomically executed.

But transactions are not only about updating the database but also about performing atomic reads. With Speedment, we can compute values atomically using Java streams and then return the result to something outside the scope of the transaction in an easy way.

Java 8 lambdas and the GC - Objection

Ok, so I was playing with WeakReferences in java (as you do) and had written some code where you could add lots of listeners/subscribers/whatever to this …well publisher I guess. There would be only one publisher, but potentially lots of subscribers, so I figured I'd try wrapping the listeners in WeakReferences, so I wouldn't have to worry about having to match each addListener() call with a removeListener() to avoid a potential memory leak.

AWS Developer Forums: Lambda leaking memory with dire ...

I'm using somewhat controversial, albeit absolutely legitimate use case for AWS Lambda functions: recursion. A lambda function, just before termination, is using AWS.Lambda.invokeAsync() to invoke itself. There is some extra code to prevent accidental uncontrolled multiplication of execution threads, there is only one instance running at the time. The problem is that with each invocation the amount of memory used increases. The first invocation is around 15MB, then it's gradually increasing up to the limit specified in settings, in this case 128MB. What happens then is somewhat unpredictable. In most cases some garbage collection (or probably restart of node.js instance) takes place and the next invocation is again below 20MB. Occasionally, the invocations will fail without apparent reason and the recursion will stop. Below is such a sequence of events, additional suspicious behaviour is that GUID of the invocations were the same (5436599f-7975-11e4-aee2-172cf7400691) in the few terminal starts.

尝试Java加锁新思路：原子变量和非阻塞同步算法 - 简书

我们以非阻塞的栈为例说明非拥塞算法的设计思路。创建非阻塞算法的关键在于将原子修改的范围缩小到单个变量上，同时保证数据一致性。

栈是最简单的链式数据结构：每个元素仅仅指向一个元素，每个元素也仅被一个元素引用，关键的操作入栈（push）和出栈（pop）都是针对于栈顶元素（top）的。因此每次操作只需要保证栈顶元素的一致性，将原子操作的范围控制在指向栈顶元素的引用即可。实例代码如下：

java - Lambda reference to a field - Stack Overflow

It sounds like you're hoping that Java has a corresponding feature for field references as it does for method references. But this is not the case. Method references are shorthand for a certain category of lambda expressions, but there is no corresponding syntax for fields. Field literals were explored during the JSR-335 Expert Group deliberation (there is some reference to it here http://mail.openjdk.java.net/pipermail/lambda-dev/2011-November/004235.html) but were not included in Java SE 8.

美国企业的装嫩问题

这些"新奇"，"年轻"的企业文化，似乎很容易吸引刚走出学校，未经世事的年轻人，然而在一个成熟的人看来，这些公司并没有显示出真正的活力，而是显示出愚蠢和虚伪。事实证明，缺乏隔离措施的所谓"开放空间"办公室，并不如传统的单间办公室或者隔离间（cubicle）。编程需要的是独立思考，思考需要集中注意力，很多人思考时甚至不喜欢别人能直接看见自己。没有隔离和隐私措施的办公室，使得员工之间随时都可以互相干扰，难以集中注意力，这对于写出优雅清晰的代码是很不利的。要是遇到那种成天高谈阔论的人在你旁边，那就更倒霉了，不得不成天戴着耳机工作。有些人时不时地发动 NERF 枪战，不但极大地干扰其他人的正常工作，而且制造一种浮躁虚假的氛围，你甚至可能因此受伤。至于 Agile，站会，试用新语言，采用结对编程，鼓吹 TDD，突发奇想的新管理方式，等等，都是 startup 的通病。很多新公司没有经验，不知道什么是真正好的技术和管理方式，再加上不小心招进来不懂装懂的管理者，所以走一步错一步，浪费大量的资源，一步步地走向失败。

java - Google's Json Parsing Gson library: What's the difference between JsonElement and JsonObject? - Stack Overflow

JsonElement is the base type for all of the different specific types - it's a base class with common things that all nodes should implement. Logically, this makes a lot of sence.

The thing that all specific types inherits from JsonElement is a good thing for you, too. It allows you to test if an object is a Json node representation, simply by checking if it inherits from JsonElement.

The JsonElement class is available to you as a public class probably not because you'd want to subclass it, but because you'd want to test for its subclasses.

阿里Dubbo疯狂更新，关Spring Cloud什么事？

但它们两者的出发点是不一样的，Dubbo 关注于服务治理这块并且以后也会继续往这个方向去发展。

Spring Cloud 关注的是微服务治理的生态。因为微服务治理的方方面面都是它所关注的内容，服务治理也只是微服务生态的一部分而已。

因此可以大胆的断定，Dubbo 未来会在服务治理方面更为出色，而 Spring Cloud 在微服务治理上面无人能敌。

同时根据 Dubbo 最新的更新技术来看，Dubbo 也会积极的拥抱开源，拥抱新技术。

Dubbo 接下来的版本将会很快的支持 Spring Boot，方便我们享受高效开发的同时，也可以支持高效的服务调用。

Dubbo 被广泛应用于中国各互联网公司，如今阿里又重新重视起来并且发布了新版本和一系列的计划，对于正在使用 Dubbo 的公司来说是一个喜讯，对于中国广大的开发者来说更是一件非常喜悦的事情。

coding style - Exception messages and event logging - which tense to use? - Software Engineering Stack Exchange

I like to use present tense when the error/exception-generating code is the "root cause" of the problem, and past tense when I'm merely repackaging an error/exception from a lower layer of code.

For example, when our frontend makes a request to our backend, the backend may return an error message "Cannot connect to database", and the frontend will throw "Failed to retrieve your widgets because: Cannot connect to database".

In general, the only "best practices" in regards to exception/error wording are to make it as clear, unambiguous, non-misleading and consistent as possible. In my opinion the tense convention I just described fits those criteria the best, but there are probably other equally valid conventions.

cp - Strange behaviour in recursive copy - Unix & Linux Stack Exchange

For cp, the destination is the last argument on the command line. You have specified 2/g as the last argument.

Before cp is executed, the command parameters are expanded. 1/* expands to 1/a 1/b 1/c. 2/* expands to 2/f 2/g. The final executed command is cp -r 1/a 1/b 1/c 2/f 2/g, which will copy all the arguments (except the last one) to 2/g.

If you are intending to copy things to 2, the second glob isn't necessary, making the command cp -r 1/* 2/. If you are intending to copy things to multiple destinations, you can't specify that with just cp; you can use a small loop, like the following:

What is the difference between a mortgage interest rate and an APR?

The interest rate is the cost you will pay each year to borrow the money, expressed as a percentage rate. It does not reflect fees or any other charges you may have to pay for the loan.

An annual percentage rate (APR) is a broader measure of the cost to you of borrowing money, also expressed as a percentage rate. In general, the APR reflects not only the interest rate but also any points, mortgage broker fees, and other charges that you pay to get the loan. For that reason, your APR is usually higher than your interest rate.

MockitoJUnitRunner gives you automatic validation of framework usage, as well as an automatic initMocks().

The automatic validation of framework usage is actually worth having. It gives you better reporting if you make one of these mistakes.

You call the static when method, but don't complete the stubbing with a matching thenReturn, thenThrow or then. (Error 1 in the code below)
You call verify on a mock, but forget to provide the method call that you are trying to verify. (Error 2 in the code below)
You call the when method after doReturn, doThrow or doAnswer and pass a mock, but forget to provide the method that you are trying to stub. (Error 3 in the code below)

If you don't have validation of framework usage, these mistakes are not reported until the following call to a Mockito method. This might be

in the same test method (like error 1 below),
in the next test method (like error 2 below),
in the next test class.
