  1. Fight My Monster Architecture in 5 mins! - We computing engineers live in exciting times. The Internet and its supporting infrastructures really have come of age, and all of a sudden things can, and mostly importantly should be done in new ways. Some small teams are successfully scaling enterprises to massive scale on tiny budgets, and the new generation of applications and games [...] What I am reading
  2. ConcurrentHashMap – avoid a common misuse! - If you program systems with Java, you have probably long been using ConcurrentHashMap. This post explores a caveat. ConcurrentHashMap is often introduced to simplify code and application logic. For example: HashMap<String, MyClass> m = new HashMap<String, MyClass>(); ... synchronized (m) {     for each (Entry<String, MyClass> e in m.entrySet())         system.out.println(e.getKey()+"="+e.getValue()); [...] What I am reading

Thanks too to Moshi for setting an inspiring example. Please note we want to be as big as Moshi Monsters, not imitate them! The game design and vision are very different. [...] What I am reading

  2. Differentiation through Obfuscation - Every software vendor needs to convince you that their product is _different_ from all the others. Unfortunately, one of the most common strategies for differentiation is obfuscation.
  3. The Tortoise and the Hare - In software the race goes to those who go well, not those who go fast.
  4. Modelling the real world. - The concept of modeling the real world has been so badly abused in the OO community, that I want to find the person who first coined the notion and flay him alive. (not really.)

Eclipse On E

  1. Skip over certain classes when using Step Into in Eclipse’s debugger - Whenever I use the Step Into feature (F5) in Eclipse’s debugger, I’m mainly interested in stepping through code in my own classes, not the ones from external libraries or even Java classes. For example, there’s almost no reason to ever want to step into Spring’s code or proxy classes (other than to learn more about […] What I am reading
  2. The easiest ways to navigate methods in a class using Eclipse keyboard shortcuts - Java classes can get big and hairy, making it difficult to find the method you’re looking for when browsing or editing a class. There is no specific order to where methods can be in a class and different developers have different preferences about where to put them. You could use the mouse wheel and scroll […] What I am reading
  3. Generate, rename and delete getters/setters instantly in Eclipse - Despite the arguments and debates about getters and setters in Java, the fact is that they’re a reality and you have to work with them. But managing getters and setters is a time-consuming effort. Creating a getter/setter for 5 fields in a class can take minutes, renaming one is error-prone and deleting one is just […] What I am reading
  4. The fastest ways to open editors in Eclipse using the keyboard - Something you do a lot in Eclipse is open files such as classes, XML files and property files in editors. But using the mouse to hunt through the Package Explorer folder hierarchy takes a long time, especially if you forgot where the files are located. The problem gets worse the more projects and files you […] What I am reading

Configure those annoying tooltips in Eclipse to only popup on request - Whenever you hover over any piece of code in Eclipse, it pops up a tooltip that displays more information about the item, such as its declaration, variable values or Javadoc information, as in the example below. Although useful at times, this becomes extremely annoying after a while, especially when you’re using your mouse to browse […] What I am reading

Exception handling is an aspect of Java development that has not received as much attention as it deserves. If you do not have exception handling under control, you risk that your application or data ends up in an unhealthy state, which can have serious consequences. That is why I wrote this book.

  2. Specifing arrays size/capacity – my latest buggy code and a best practice - We’re often required to specify size/capacity when allocating array like structures.

  1. Amazon Redshift and Designing for Security -

    It’s been a few months since I last wrote about Amazon Redshift and I thought I’d update you on some of the things we are hearing from customers. Since we launched, we’ve been adding over a hundred customers a week and are well over a thousand today. That’s pretty stunning. As far as I know, it’s unprecedented for this space. We’ve enabled our customers to save tens of millions of dollars in up front capital expenses by using Amazon Redshift.

    It’s clear that Amazon Redshift’s message of price, performance and simplicity has resonated with our customers. That’s no surprise – these are core principles for every AWS service. But when we launched Amazon Redshift, a number of people asked me, “Aren’t data warehouses enterprise products? Do you really do enterprise? How do you handle availability, security, and integration?” My first reaction to that was, “Wait, doesn’t everybody care about these things? These aren’t enterprise-specific.” But, even if we accept that framing, we don’t have to limit ourselves to the enterprise. A lot of the power of AWS comes from the fact that we can invest in expertise in these sorts of areas and spread the benefits across all our customers. I’ve talked about performance and availability in Amazon Redshift before. This time, let’s take a look at how Amazon Redshift secures your data. I suspect it’s a lot more than what most people are doing on premise today. This is especially timely since Amazon Redshift has just been included in our SOC1 and SOC2 compliance reports.

    Amazon Redshift starts with the security foundation underlying all AWS services. There are physical controls for datacenter access. Machines are wiped before they are provisioned. Physical media is destroyed before leaving our facilities. Drivers, BIOS, and NICs are protected. Access by our staff is monitored, logged and audited.

    As a managed service, Amazon Redshift builds on this foundation by automatically configuring multiple firewalls, known as security groups, to control access to customer data warehouse clusters. Customers can explicitly set up ingress and egress rules or place their SQL endpoint inside their own VPC, isolating it from the rest of the AWS cloud. For multi-node clusters, the nodes storing customer data are isolated in their own security group, preventing direct access by the customer or the rest of the AWS network. Customers can require SSL for their own accesses to their cluster while the AWS operations to monitor and manage their cluster are always secured by SSL.

    redshiftsecure What I am reading

    Amazon Redshift can also be set up to encrypt all data at rest using hardware-accelerated AES-256. All data includes all data blocks, system metadata, partial results from queries and backups stored in S3. Each data block gets its own unique randomly generated key. These keys are further encrypted with a randomly generated cluster-specific key that is encrypted and stored off-cluster, outside the AWS network, and only kept in-memory on the cluster itself. By using unique keys per-block and per-cluster, Amazon Redshift dramatically reduces the cost of key rotation and helps prevent unauthorized splicing of data from different blocks or clusters. We plan to support customer-managed hardware security modules (HSM) by further encrypting the cluster key, using Amazon CloudHSM or an on-premise HSM environment.

    I always tell developers that they should obsess not only on the things that our customers ask for but also on the things they just expect. Chief amongst those is security. Every day, we need to come in and work hard to maintain the trust our customers have placed in us. I’m delighted to see how much work the Amazon Redshift team put into this area out of the gate.
