  • Rationale behind freeware projects

    - by VexXtreme
    I've seen some freeware projects in the past where the author(s) invested a significant amount of their personal time and resources and never even considered charging for the software. A lot of these projects were donation based, and from what I've heard, donationware can never be a viable business model (even to simply support development costs) because most people choose not to donate if given an option. A lot of these projects eventually shut down because their authors could not sustain them further. Granted, some people simply like making the community happy (or something), but if you're struggling to keep your project alive, why not charge some small amount such as $10 simply to stay operational? If people find your software useful (and a lot of people found those projects VERY useful) they won't have a problem paying such a small amount. The question is: if you have a popular app that people like and download in great numbers, why not put a price tag on it? Why do it for free?

  • WP: Oracle Multitenant on SuperCluster T5-8: Study of Database Consolidation Efficiency

    - by uwes
    Consolidation in the data center is the driving factor in reducing capital and operational expense in IT today. This is particularly relevant as customers invest more in cloud infrastructure and associated service delivery. Database consolidation is a strategic component in this effort. Oracle Database 12 c introduces Oracle Multitenant , a new database consolidation model in which multiple Pluggable Databases (PDBs) are consolidated within a Container Database (CDB). While keeping many of the isolation aspects of single databases, it allows PDBs to share the system global area (SGA) and background processes of a common CDB . The white paper recently published on OTN: Oracle Multitenant on SuperCluster T5-8: Study of Database Consolidation Efficiency analyzes and quantifies savings in compute resources, efficiencies in transaction processing, and consolidation density of Oracle Multitenant compared to consolidated single instance databases (SIDBs) running in a bare-metal environment.

  • BPM in Financial Services Industry

    - by Sanjeev Sharma
    The following series of blog posts discuss common BPM use-cases in the Financial Services industry: Financial institutions view compliance as a regulatory burden that incurs a high initial capital outlay and recurring costs. By its very nature regulation takes a prescriptive, common-for-all, approach to managing financial and non-financial risk. Needless to say, no longer does mere compliance with regulation will lead to sustainable differentiation. For details, check out the 2 part series on managing operational risk of financial services process (part 1 / part 2). Payments processing is a central activity for financial institutions, especially retail banks, and intermediaries that provided clearing and settlement services. Visibility of payments processing is essentially about the ability to track payments and handle payments exceptions as payments flow from initiation to settlement. For details, check out the 2 part series on improving visibility of payments processing (part 1 / part 2).

  • BURG broken by Windows

    - by Sallée
    I have successfully installed, using Super Boot Manager, BURG in a computer at my work. After I boot into Windows XP, BURG is no longer operational. The machine just boots to the BIOS screen, goes black, and then boots to the BIOS screen again ad infinitum. The only way to recover I have found so far is to use a Boot-Repair USB, which restores either GRUB2 or MBR, not BURG. Everything works fine under GRUB2, but I prefer the improved look of BURG to make things easier on my students.

  • How do you track Production tasks.

    - by M.C
    I manage a team of coders (5people) that maintain a few modules in a large project. On top of doing coding, we also do production operational tasks (like doing server housekeeping, batch backlog tracking) These tasks are done daily, done by 1 person, and is rotated weekly The problem is this: These tasks are routine, but there I cant think of a practical way of ensuring the person does what he is supposed to do. I thought of using spreadsheets to track, or to the extent of doing a paper checklist, which the person on duty will have to physically sign off. I just want the guy on duty to remember and execute every daily item. What works on your project?

  • $_POST vs. $_SERVER['REQUEST_METHOD'] == 'POST'

    - by Scott
    Some guy called one of my Snipplr submissions "crap" because I used if ($_SERVER['REQUEST_METHOD'] == 'POST') instead of if ($_POST) Checking the request method seems more correct to me because that's what I really want to do. Is there some operational difference between the two or is this just a code clarity issue?

  • SQL SERVER – Core Concepts – Elasticity, Scalability and ACID Properties – Exploring NuoDB an Elastically Scalable Database System

    - by pinaldave
    I have been recently exploring Elasticity and Scalability attributes of databases. You can see that in my earlier blog posts about NuoDB where I wanted to look at Elasticity and Scalability concepts. The concepts are very interesting, and intriguing as well. I have discussed these concepts with my friend Joyti M and together we have come up with this interesting read. The goal of this article is to answer following simple questions What is Elasticity? What is Scalability? How ACID properties vary from NOSQL Concepts? What are the prevailing problems in the current database system architectures? Why is NuoDB  an innovative and welcome change in database paradigm? Elasticity This word’s original form is used in many different ways and honestly it does do a decent job in holding things together over the years as a person grows and contracts. Within the tech world, and specifically related to software systems (database, application servers), it has come to mean a few things - allow stretching of resources without reaching the breaking point (on demand). What are resources in this context? Resources are the usual suspects – RAM/CPU/IO/Bandwidth in the form of a container (a process or bunch of processes combined as modules). When it is about increasing resources the simplest idea which comes to mind is the addition of another container. Another container means adding a brand new physical node. When it is about adding a new node there are two questions which comes to mind. 1) Can we add another node to our software system? 2) If yes, does adding new node cause downtime for the system? Let us assume we have added new node, let us see what the new needs of the system are when a new node is added. Balancing incoming requests to multiple nodes Synchronization of a shared state across multiple nodes Identification of “downstate” and resolution action to bring it to “upstate” Well, adding a new node has its advantages as well. Here are few of the positive points Throughput can increase nearly horizontally across the node throughout the system Response times of application will increase as in-between layer interactions will be improved Now, Let us put the above concepts in the perspective of a Database. When we mention the term “running out of resources” or “application is bound to resources” the resources can be CPU, Memory or Bandwidth. The regular approach to “gain scalability” in the database is to look around for bottlenecks and increase the bottlenecked resource. When we have memory as a bottleneck we look at the data buffers, locks, query plans or indexes. After a point even this is not enough as there needs to be an efficient way of managing such large workload on a “single machine” across memory and CPU bound (right kind of scheduling)  workload. We next move on to either read/write separation of the workload or functionality-based sharing so that we still have control of the individual. But this requires lots of planning and change in client systems in terms of knowing where to go/update/read and for reporting applications to “aggregate the data” in an intelligent way. What we ideally need is an intelligent layer which allows us to do these things without us getting into managing, monitoring and distributing the workload. Scalability In the context of database/applications, scalability means three main things Ability to handle normal loads without pressure E.g. X users at the Y utilization of resources (CPU, Memory, Bandwidth) on the Z kind of hardware (4 processor, 32 GB machine with 15000 RPM SATA drives and 1 GHz Network switch) with T throughput Ability to scale up to expected peak load which is greater than normal load with acceptable response times Ability to provide acceptable response times across the system E.g. Response time in S milliseconds (or agreed upon unit of measure) – 90% of the time The Issue – Need of Scale In normal cases one can plan for the load testing to test out normal, peak, and stress scenarios to ensure specific hardware meets the needs. With help from Hardware and Software partners and best practices, bottlenecks can be identified and requisite resources added to the system. Unfortunately this vertical scale is expensive and difficult to achieve and most of the operational people need the ability to scale horizontally. This helps in getting better throughput as there are physical limits in terms of adding resources (Memory, CPU, Bandwidth and Storage) indefinitely. Today we have different options to achieve scalability: Read & Write Separation The idea here is to do actual writes to one store and configure slaves receiving the latest data with acceptable delays. Slaves can be used for balancing out reads. We can also explore functional separation or sharing as well. We can separate data operations by a specific identifier (e.g. region, year, month) and consolidate it for reporting purposes. For functional separation the major disadvantage is when schema changes or workload pattern changes. As the requirement grows one still needs to deal with scale need in manual ways by providing an abstraction in the middle tier code. Using NOSQL solutions The idea is to flatten out the structures in general to keep all values which are retrieved together at the same store and provide flexible schema. The issue with the stores is that they are compromising on mostly consistency (no ACID guarantees) and one has to use NON-SQL dialect to work with the store. The other major issue is about education with NOSQL solutions. Would one really want to make these compromises on the ability to connect and retrieve in simple SQL manner and learn other skill sets? Or for that matter give up on ACID guarantee and start dealing with consistency issues? Hybrid Deployment – Mac, Linux, Cloud, and Windows One of the challenges today that we see across On-premise vs Cloud infrastructure is a difference in abilities. Take for example SQL Azure – it is wonderful in its concepts of throttling (as it is shared deployment) of resources and ability to scale using federation. However, the same abilities are not available on premise. This is not a mistake, mind you – but a compromise of the sweet spot of workloads, customer requirements and operational SLAs which can be supported by the team. In today’s world it is imperative that databases are available across operating systems – which are a commodity and used by developers of all hues. An Ideal Database Ability List A system which allows a linear scale of the system (increase in throughput with reasonable response time) with the addition of resources A system which does not compromise on the ACID guarantees and require developers to learn new paradigms A system which does not force fit a new way interacting with database by learning Non-SQL dialect A system which does not force fit its mechanisms for providing availability across its various modules. Well NuoDB is the first database which has all of the above abilities and much more. In future articles I will cover my hands-on experience with it.
