• Mastering Online Outsourcing

  Two things that have really helped me with my online marketing over the years are having an accountability partner and outsourcing. Also learning how well a solution to some problem will work out when the size of the problem increases. Most people think, I'll develop my business when it is time to develop it. The thing is developing over time can be the downfall of a business if not watched carefully.

• Flags with deferred use

  - by Trenton Maki

  Let's say I have a system. In this system I have a number of operations I can do but all of these operations have to happen as a batch at a certain time, while calls to activate and deactivate these operations can come in at any time. To implement this, I could use flags like doOperation1 and doOperation2 but this seems like it would become difficult to maintain. Is there a design pattern, or something similar, that addresses this situation?

• Should the test and the fix be written by different people?

  - by Nutel

  There is a common practice in TDD to write a test before fix to avoid regression and simplify fixing. I just wonder what if the test and fix will be written by different people, total spent time will be almost the same but as now three people will think about possible failures (+tester) we increase probability that fix will cover all possible failure scenarios. Does this practice make sense or it will just waste additional time needed for one more person to familiarize with bug?

• On ESXi, guest machines hang for significant intervals compared to real machines. How can I fix this?

  - by Tarbox

  This is ESXi version 5.0.0. We plan on upgrading to 5.5 eventually. I have four code profiles, two taken on a real, unvirtualized machine, two taken on a virtual machine. Ordering the list of subroutines by time spent in each one, the two real profiles are practically identical. The two virtual profiles are different from each other and from the real profiles: a subset of subroutines are taking a lot more time on the virtual machines, and the subset is different for each run. The two virtual profiles take a similar amount of time, which is 3 times the amount of time the real profiles take. This gross "how long does it take?" result is consistent after hundreds of tests across three different virtual machines on two different host machines -- the virtual machine is just slower. I've only the code profiling on the four, however. Here's the most guilty set of lines: This is the real machine: 8µs $text = '' unless defined $text; 1.48ms foreach ( split( "\n", $text ) ) { This is the first run on the virtual machine: 20.1ms $text = '' unless defined $text; 1.49ms foreach ( split( "\n", $text ) ) { This is the second run on the virtual machine: 6µs $text = '' unless defined $text; 21.9ms foreach ( split( "\n", $text ) ) { My WAG is that the VM is swapping out the thread and then swapping it back in, destroying some level of cache in the process, but these code profiles were taken when the vm in question was the only active vm on the host, so... what? What does that mean? The guest itself is under light load, this is a latency problem for my users rather than throughput. The host is also under a light load, if I knew what resources to assign where, I could do it without worrying about the cost. I've attempted to lock memory, reserve cpu, assign a restrictive affinity, and disable hyperthread sharing. They don't help, it still takes the VM 2-4x the amount of time to do the same thing as the real machine. The host the tests were run on is 6x2.50GHz, Intel Xeon E5-26400 w/ 16gigs of ram. The guest exhibits the same performance under a wide combination of settings. The real machine is 4x2.13GHz, Xeon E5506 w/ 2 gigs of ram. Thank you for all advice.

• 5 years of university education vs. 5 years of work experience - Which would you pick if hiring? [closed]

  - by gablin

  Say you need to hire a programmer. You have two candidates at your table: one has studied 5 years at uni (and holds a Master's degree, of course), but has no work experience; and the other holds no university degree but has worked for 5 years. Also assume that they both know the same programming languages, have about the same personality and spend equal amount of time programming on their spare time. If you only had this information to go on, which would you pick?

  With the new iPhone 5 being as powerful as the supercomputers of the 1980s, its only a matter of time when the latest phones will be powerful enough to run a twitter-scale web application from within my pocket. When that time comes, performance will no longer be something programmers need to care about. Will low level languages still have a place? Or will everyone move to dynamic languages like Python?

• Why is my concurrency capacity so low for my web app on a LAMP EC2 instance?

  - by AMF

  I come from a web developer background and have been humming along building my PHP app, using the CakePHP framework. The problem arose when I began the ab (Apache Bench) testing on the Amazon EC2 instance in which the app resides. I'm getting pretty horrendous average page load times, even though I'm running a c1.medium instance (2 cores, 2GB RAM), and I think I'm doing everything right. I would run: ab -n 200 -c 20 http://localhost/heavy-but-view-cached-page.php Here are the results: Concurrency Level: 20 Time taken for tests: 48.197 seconds Complete requests: 200 Failed requests: 0 Write errors: 0 Total transferred: 392111200 bytes HTML transferred: 392047600 bytes Requests per second: 4.15 [#/sec] (mean) Time per request: 4819.723 [ms] (mean) Time per request: 240.986 [ms] (mean, across all concurrent requests) Transfer rate: 7944.88 [Kbytes/sec] received While the ab test is running, I run VMStat, which shows that Swap stays at 0, CPU is constantly at 80-100% (although I'm not sure I can trust this on a VM), RAM utilization ramps up to about 1.6G (leaving 400M free). Load goes up to about 8 and site slows to a crawl. Here's what I think I'm doing right on the code side: In Chrome browser uncached pages typically load in 800-1000ms, and cached pages load in 300-500ms. Not stunning, but not terrible either. Thanks to view caching, there might be at most one DB query per page-load to write session data. So we can rule out a DB bottleneck. I have APC on. I am using Memcached to serve the view cache and other site caches. xhprof code profiler shows that cached pages take up 10MB-40MB in memory and 100ms - 1000ms in wall time. Pages that would be the worst offenders would look something like this in xhprof: Total Incl. Wall Time (microsec): 330,143 microsecs Total Incl. CPU (microsecs): 320,019 microsecs Total Incl. MemUse (bytes): 36,786,192 bytes Total Incl. PeakMemUse (bytes): 46,667,008 bytes Number of Function Calls: 5,195 My Apache config: KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 3 <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 120 MaxRequestsPerChild 1000 </IfModule> Is there something wrong with the server? Some gotcha with the EC2? Or is it my code? Some obvious setting I should look into? Too many DNS lookups? What am I missing? I really want to get to 1,000 concurrency capacity, but at this rate, it ain't gonna happen.

• Can Anything be Done to Make Improv (a 1993 Win 3.1 App) handle larger Files?

  - by user75185

  My very favorite spradsheet is Improv, a 1993 Windows 3.1 application. It still puts Excel to shame for building spreadsheets and writing formulas. The only problem is because Improv was written when 1 Meg of RAM was state of the art, it becomes unstable when working with larger spreadsheets and often crashes and/or corrupts the data file. I am working on a project that greatly exceeds Improv's limits. Although it will ultimately require more robust databasing capability, I could save a lot of critical time if I could delay that headache and continue working in Improv for now. To that end, I moved to the only product I could find that comes close, Quantrix, which is nothing more than Improv updated to handle large spreadsheets and utilize today's technologies. The problems with Quantrix are its speed (significantly slower than Improv) and its $1000 price (which I cannot afford). I have already had 3 15 day extensions after the initial 30 day trial, so my time to use Quantrix as a bridge is at its end. Searches for Improv over the years have gotten me nowhere and, not surprisingly after reading some posts on this site, I got nothing for the money and time invested to find a programmer to write code to "fix" this problem. Improv is freely available as "abandonware" at http://vetusware.com/download/LotusImprov2.1/?id=5797 , and the best background info can be found on Wikipedia and at "Moose's Greatest Software Products of All Time - Lotus Improv" http://moosevalley.fhost.com.au/mooses_review_page_lotus_improv.html It is critically urgent for me to focus on analyzing the data asap. Working in a stable Improv would, without question, be the fastest route. To that end, I am looking for answers to the following questions and anything else that might be helpful: 1) Is it lawful to hire someone to fix Improv for my own use? If so, 2) About how much should it cost? 3) About how long should it take? 4) What skills should I be looking for &/or how should a post be worded? 5) Is there a niche site where it should it be posted? 6) What questions can I ask to quickly screen candidates? Since I am not a programmer, I need questions the answers to which leave no room to confuse me, whether intentional or not. For example, what tools or players should someone with an acceptable competency level have knowledge of?

• Beyond Cloud Technology, Enabling A More Agile and Responsive Organization

  - by sxkumar

  This is the second part of the blog “Clouds, Clouds Everywhere But not a Drop of Rain”. In the first part,  I was sharing with you how a broad-based transformation makes cloud more than a technology initiative, I will describe in this section how it requires people (organizational) and process changes as well, and these changes are as critical as is the choice of right tools and technology. People: Most IT organizations have a fairly complex organizational structure. There are different groups, managing different pieces of the puzzle, and yet, they don't always work together. Provisioning a new application therefore may require a request to float endlessly through system administrators, DBAs and middleware admin worlds – resulting in long delays and constant finger pointing.  Cloud users expect end-to-end automation - which requires these silos to be greatly simplified, if not completely eliminated.  Most customers I talk to acknowledge this problem but are quick to admit that such a transformation is hard. As hard as it may be, I am afraid that the status quo is no longer an option. Sticking to an organizational structure that was created ages back will not only impede cloud adoption,  it also risks making the IT skills increasingly irrelevant in a world that is rapidly moving towards converged applications and infrastructure.   Process: Most IT organizations today operate with a mindset that they must fully "control" access to any and all types of IT services. This in turn leads to people clinging on to outdated manual approval processes .  While requiring approvals for scarce resources makes sense, insisting that every single request must be manually approved defeats the very purpose of cloud. Not only this causes delays, thereby at least partially negating the agility benefits, it also results in gross inefficiency. In a cloud environment, self-service access should be governed by policies, quotas that the administrators can define upfront . For a cloud initiative to be successful, IT organizations MUST be ready to empower users by giving them real control rather than insisting on brokering every single interaction between users and the cloud resources. Technology: From a technology perspective, cloud is about consolidation, standardization and automation. A consolidated and standardized infrastructure helps increase utilization and reduces cost. Additionally, it  enables a much higher degree of automation - thereby providing users the required agility while minimizing operational costs.  Obviously, automation is the key to cloud. Unfortunately it hasn’t received as much attention within enterprises as it should have.  Many organizations are just now waking up to the criticality of automation and it still often gets relegated to back burner in favor of other "high priority" projects. However, it is important to understand that without the right type and level of automation, cloud will remain a distant dream for most enterprises. This in turn makes the choice of the cloud management software extremely critical.  For a cloud management software to be effective in an enterprise environment, it must meet the following qualifications: Broad and Deep Solution It should offer a broad and deep solution to enable the kind of broad-based transformation we are talking about.  Its footprint must cover physical and virtual systems, as well as infrastructure, database and application tiers. Too many enterprises choose to equate cloud with virtualization. While virtualization is a critical component of a cloud solution, it is just a component and not the whole solution. Similarly, too many people tend to equate cloud with Infrastructure-as-a-Service (IaaS). While it is perfectly reasonable to treat IaaS as a starting point, it is important to realize that it is just the first stepping stone - and on its own it can only provide limited business benefits. It is actually the higher level services, such as (application) platform and business applications, that will bring about a more meaningful transformation to your enterprise. Run and Manage Efficiently Your Mission Critical Applications It should not only be able to run your mission critical applications, it should do so better than before.  For enterprises, applications and data are the critical business assets  As such, if you are building a cloud platform that cannot run your ERP application, it isn't truly a "enterprise cloud".  Also, be wary of  vendors who try to sell you the idea that your applications must be written in a certain way to be able to run on the cloud. That is nothing but a bogus, self-serving argument. For the cloud to be meaningful to enterprises, it should adopt to your applications - and not the other way around.  Automated, Integrated Set of Cloud Management Capabilities At the root of many of the problems plaguing enterprise IT today is complexity. A complex maze of tools and technology, coupled with archaic  processes, results in an environment which is inflexible, inefficient and simply too hard to manage. Management tool consolidation, therefore, is key to the success of your cloud as tool proliferation adds to complexity, encourages compartmentalization and defeats the very purpose that you are building the cloud for. Decision makers ought to be extra cautious about vendors trying to sell them a "suite" of disparate and loosely integrated products as a cloud solution.  An effective enterprise cloud management solution needs to provide a tightly integrated set of capabilities for all aspects of cloud lifecycle management. A simple question to ask: will your environment be more or less complex after you implement your cloud? More often than not, the answer will surprise you.  At Oracle, we have understood these challenges and have been working hard to create cloud solutions that are relevant and meaningful for enterprises.  And we have been doing it for much longer than you may think. Oracle was one of the very first enterprise software companies to make our products available on the Amazon Cloud. As far back as in 2007, we created new cloud solutions such as Cloud Database Backup that are helping customers like Amazon save millions every year.  Our cloud solution portfolio is also the broadest and most deep in the industry  - covering public, private, hybrid, Infrastructure, platform and applications clouds. It is no coincidence therefore that the Oracle Cloud today offers the most comprehensive set of public cloud services in the industry.  And to a large part, this has been made possible thanks to our years on investment in creating cloud enabling technologies. I will dedicated the third and final part of the blog “Clouds, Clouds Everywhere But not a Drop of Rain” to Oracle Cloud Technologies Building Blocks and how they mapped into our vision of Enterprise Cloud. Stay Tuned.
