In my continued playing around with web logs in R I wanted to process the logs for a day and see what the most popular URIs were. I first read in all the lines using the read_lines function in readr and put the vector it produced into a data frame so I could process it using dplyr. library(readr) dlines = data.frame(column = read_lines("~/projects/logs/2015-06-18-22-docs")) In the previous post I showed some code to extract the URI from a log line. I extracted this code out into a function and adapted it so that I could pass in a list of values instead of a single value: extract_uri = function(log) { parts = str_extract_all(log, "\"[^\"]*\"") return(lapply(parts, function(p) str_match(p[1], "GET (.*) HTTP")[2] %>% as.character)) } Next I ran the following function to count the number of times each URI appeared in the logs: library(dplyr) pages_viewed = dlines %>% mutate(uri = extract_uri(column)) %>% count(uri) %>% arrange(desc(n)) This crashed my R process with the following error message: segfault cause 'memory not mapped' I narrowed it down to a problem when doing a group by operation on the ‘uri’ field and came across this post which suggested that it was handled more cleanly in more recently version of dplyr. I upgraded to 0.4.2 and tried again: ## Error in eval(expr, envir, enclos): cannot group column uri, of class 'list' That makes more sense. We’re probably returning a list from extract_uri rather than a vector which would fit nicely back into the data frame. That’s fixed easily enough by unlisting the result: extract_uri = function(log) { parts = str_extract_all(log, "\"[^\"]*\"") return(unlist(lapply(parts, function(p) str_match(p[1], "GET (.*) HTTP")[2] %>% as.character))) } And now when we run the count function it’s happy again, good times!

I wanted to display my Android screen on Fedora during a Summit presentation which includes Feedhenry. I found an easy way to mirror my android screen on Fedora so I can show it through the presentation device (TV, Projector, etc.). So I compiled the steps below from some different references. Download the latest Android SDK from Google: Android SDK Extract the TGZ file to your home/YOUR-USERNAME directory To get ADB, you need to install the SDK: Installing the SDK Run chmode on android in tools Run android under tools and then install the Android SDK Tools On your phone turn on Debugging in Developer Settings, click Settings > Developer Options turn on debugging and make sure USB Debugging is on. If you are running 64-bit then to run adb you will have to enable 32-bit # yum install glibc.i686 #yum install zlib.i686 libstdc++.i686 ncurses-libs.i686 libgcc.i686 You need to add a udev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. For a list of vendor IDs, see USB Vendor IDs, To set up device detection on Linux: Log in as root and create this file: /etc/udev/rules.d/51-android.rules. Use this format to add each vendor to the file: SUBSYSTEM=="usb", ATTR{idVendor}=="xxxx", MODE="0666" [summit2015@localhost tools]$ cat /etc/udev/rules.d/51-android.rules SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", MODE="0666" [summit2015@localhost tools]$ Note: The rule syntax may vary slightly depending on your environment. Consult the udevdocumentation for your system as needed. For an overview of rule syntax, see this guide towriting udev rules. Now execute: chmod a+r /etc/udev/rules.d/51-android.rules When plugged in over USB, you can verify that your device is connected by executing adb devices from your SDK platform-tools/ directory. If connected, you'll see the device name listed as a "device." [summit2015@localhost platform-tools]$ ./adb devices List of devices attached 0A3D267016016004 device [summit2015@localhost platform-tools]$ NOTE: I ran android update adb and adb server-start to test prior to the above command but these shouldn't be required Next I download Droid@Screen and then ran java -jar droidAtScreen-1.1.jar That's all that is required!

I’ve been playing around with some web logs using R and I wanted to extract everything that existed in double quotes within a logged entry. This is an example of a log entry that I want to parse: log = '2015-06-18-22:277:548311224723746831\t2015-06-18T22:00:11\t2015-06-18T22:00:05Z\t93317114\tip-127-0-0-1\t127.0.0.5\tUser\tNotice\tneo4j.com.access.log\t127.0.0.3 - - [18/Jun/2015:22:00:11 +0000] "GET /docs/stable/query-updating.html HTTP/1.1" 304 0 "http://neo4j.com/docs/stable/cypher-introduction.html" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.124 Safari/537.36"' And I want to extract these 3 things: /docs/stable/query-updating.html http://neo4j.com/docs/stable/cypher-introduction.html Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.124 Safari/537.36 i.e. the URI, the referrer and browser details. I’ll be using the stringr library which seems to work quite well for this type of work. To extract these values we need to find all the occurrences of double quotes and get the text inside those quotes. We might start by using the str_match function: > library(stringr) > str_match(log, "\"[^\"]*\"") [,1] [1,] "\"GET /docs/stable/query-updating.html HTTP/1.1\"" Unfortunately that only picked up the first occurrence of the pattern so we’ve got the URI but not the referrer or browser details. I tried str_extract with similar results before I found str_extract_all which does the job: > str_extract_all(log, "\"[^\"]*\"") [[1]] [1] "\"GET /docs/stable/query-updating.html HTTP/1.1\"" [2] "\"http://neo4j.com/docs/stable/cypher-introduction.html\"" [3] "\"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.124 Safari/537.36\"" We still need to do a bit of cleanup to get rid of the ‘GET’ and ‘HTTP/1.1′ in the URI and the quotes in all of them: parts = str_extract_all(log, "\"[^\"]*\"")[[1]] uri = str_match(parts[1], "GET (.*) HTTP")[2] referer = str_match(parts[2], "\"(.*)\"")[2] browser = str_match(parts[3], "\"(.*)\"")[2] > uri [1] "/docs/stable/query-updating.html" > referer [1] "https://www.google.com/" > browser [1] "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.124 Safari/537.36" We could then go on to split out the browser string into its sub components but that’ll do for now!

Written by Stephane Combaudon. A question I often hear when customers want to set up a production PXC cluster is: “How many nodes should we use?” Three nodes is the most common deployment, but when are more nodes needed? They also ask: “Do we always need to use an even number of nodes?” This is what we’ll clarify in this post. This is all about quorum I explained in a previous post that a quorum vote is held each time one node becomes unreachable. With this vote, the remaining nodes will estimate whether it is safe to keep on serving queries. If quorum is not reached, all remaining nodes will set themselves in a state where they cannot process any query (even reads). To get the right size for you cluster, the only question you should answer is: how many nodes can simultaneously fail while leaving the cluster operational? If the answer is 1 node, then you need 3 nodes: when 1 node fails, the two remaining nodes have quorum. If the answer is 2 nodes, then you need 5 nodes. If the answer is 3 nodes, then you need 7 nodes. And so on and so forth. Remember that group communication is not free, so the more nodes in the cluster, the more expensive group communication will be. That’s why it would be a bad idea to have a cluster with 15 nodes for instance. In general we recommend that you talk to us if you think you need more than 10 nodes. What about an even number of nodes? The recommendation above always specifies odd number of nodes, so is there anything bad with an even number of nodes? Let’s take a 4-node cluster and see what happens if nodes fail: If 1 node fails, 3 nodes are remaining: they have quorum. If 2 nodes fail, 2 nodes are remaining: they no longer have quorum (remember 50% is NOT quorum). Conclusion: availability of a 4-node cluster is no better than the availability of a 3-node cluster, so why bother with a 4th node? The next question is: is a 4-node cluster less available than a 3-node cluster? Many people think so, specifically after reading this sentence from the manual: Clusters that have an even number of nodes risk split-brain conditions. Many people read this as “as soon as one node fails, this is a split-brain condition and the whole cluster stop working”. This is not correct! In a 4-node cluster, you can lose 1 node without any problem, exactly like in a 3-node cluster. This is not better but not worse. By the way the manual is not wrong! The sentence makes sense with its context. There could actually reasons why you might want to have an even number of nodes, but we will discuss that topic in the next section. Quorum with multiple data centers To provide more availability, spreading nodes in several datacenters is a common practice: if power fails in one DC, nodes are available elsewhere. The typical implementation is 3 nodes in 2 DCs: Notice that while this setup can handle any single node failure, it can’t handle all single DC failures: if we lose DC1, 2 nodes leave the cluster and the remaining node has not quorum. You can try with 4, 5 or any number of nodes and it will be easy to convince yourself that in all cases, losing one DC can make the whole cluster stop operating. If you want to be resilient to a single DC failure, you must have 3 DCs, for instance like this: Other considerations Sometimes other factors will make you choose a higher number of nodes. For instance, look at these requirements: All traffic is directed to a single node. The application should be able to fail over to another node in the same datacenter if possible. The cluster must keep operating even if one datacenter fails. The following architecture is an option (and yes, it has an even number of nodes!): Conclusion Regarding availability, it is easy to estimate the number of nodes you need for your PXC cluster. But node failures are not the only aspect to consider: Resilience to a datacenter failure can, for instance, influence the number of nodes you will be using.

Apache Camel: Jetty Component Today, I'm going to explain about the Camel's Jetty component and how to configure to the jetty component. Here, I used Spring DSL to configure the jetty component. So, let's start the camel riding. Camel's jetty component is used for HTTP/S based request/response as like classical Servlet. Jetty component consumes and produces the http request/response and support GET, POST, DELTE, PUT methods of forms. It act as a servlet as we define J2EE web project. It receive the request from the client, process it and create the response accordingly. With Jetty component we can create the HTTP based endpoints which consumes/produces http request. Now, Let's start the programming. I assume that you have created your project by using Maven. I also assume that you have added all the dependency required for camel in your project. Add the below dependency in your project's pom.xml org.apache.camel camel-jetty X.X.X After adding jetty dependency please do clean and build your project. Now, I'm going to add the endpoints which receive the incoming request and respond it accordingly. Below is the configuration based on Spring DSL. The Spring-DSL for camel-jetty component, ${header.CamelHttpMethod} == "GET" ${header.CamelHttpMethod} == "POST" We can have same component using Java DSL also. I've created the jetty component which receives the incoming http request and serve accordingly as per below. /** * This is the jetty component which creates the http endpoint which * consumes the http request and respond accordingly. * @author Ashish Mishra * @since 22-06-2015 15:02:05 * */ public class JettyCommponent extends RouteBuilder{ @Override public void configure() throws Exception { from("jetty:http://localhost:8080/makhir?continuationTimeout=100000").process( new Processor() { @Override public void process(Exchange exchange) throws Exception { String message = exchange.getIn().getBody(String.class); System.out.println("Request Body Message : " + message); String httpMethod = (String) exchange.getProperty("CamelHttpMethod"); System.out.println("Http Method : " + httpMethod); if(httpMethod.equalsIgnoreCase("GET")){ System.out.println("Add implementation for GET method and route accordingly"); } else if(httpMethod.equalsIgnoreCase("POST")){ System.out.println("Add implementation for POST method and route accordingly"); } else System.out.println("Default Implementation " + message); exchange.getOut().setBody("Response: " + message); } }); } } Now, you should add this routes in your main class which have CamelContext object. About how to add the routes in camelcontext I've explained in my first blog related to camel. That's it. Now build your project and deployed it in your ESB and try to call that endpoint by creating some java test class using http client. You can use the Jetty component as per your need in your application. It gives web servlet like features in camel routing. You can read more about camel:jetty component Apache Camel. Hope, you have enjoyed this camel ride.

Recently, I puzzled while looking for friendly email client for my Android device. And, the situation was not unique as I found all have their drawbacks. Let's look at the most popular e-mail clients for Android and try to find the best. As a result of wanderings in Google Play, I selected the six most popular Mail clients which are successful in my opinion. 1. Blue Mail Blue Mail is a popular e-mail client with support for a large number of postal services. It has very user-friendly interface and minimum setting - you must enter the mailbox password. After setting up the client immediately begins syncing - and after a few moments you will already see rows of folders with your letters. That's great - subfolders marked as investment, but, unfortunately, turn into the main folder cannot be all the folders displaying a single list. Appendix is perfectly adapted for touch screens - controlled via a mail is very convenient. It is possible to set the reminder time for a specific letter, the ability to customize the appearance and gestures, you can add a large number of accounts (different postal services, support for Exchange). Pros: free; There is no limit on the number of accounts (may, of course, is - but a lot; Not tied to a specific mail service; Convenient management (ie control gestures); Additional features (reminder filter to display messages in the application, configure the appearance of the application). Cons: You cannot collapse the subfolders to the main (if subfolders much, it turns out a long list, which is not convenient to work); The interface is not smooth - when scrolling and withdraw sidebars sometimes retarding. 2. myMail myMail is an excellent mail client aimed at an international audience. It’s offering quality services to the customers, minimum setting (no mail server, you need not). Completely free, not tied to a specific mail service, there is no limit to the number of connected accounts. This is management friendly and comfortable, but as such no control gestures. In the list of folders nested shifted to the right with respect to the others, in spite of that they cannot be minimized - quite convenient to use (unless, of course, subfolders are not too many). Even if the letters and added a lot of accounts - runs very smoothly. Unfortunately, there is no appearance settings, and the interface at the application seems specific enough (many may seem too "flashy"), the application has filters (for sorting mail). Pros: free; There is no limit on the number of accounts; Not tied to a specific mail service; Friendly visual interface, subfolders are shifted relative to the other; Smooth operation. Cons: Cannot be minimized subfolders in the main; Very bright interface without customization; when you reply to or forward the original formatting is lost letters. 3. Mailbox Mailbox is the popular mail client for Google and iCloud. After logging interface meets us in soothing and pleasing colors. The letters are in chronological order, depending on the strength and direction of pulling letters perform various actions - for example, just to delay the letter to the right - it is marked as executed, pull on - letter moves to the basket, if you pull the left - there also its actions. Managing convenient, but you get used - I, for example, first letter ever mistakenly moved to the Trash. It is possible to create reminders for time / date, there is an interesting sort mode analyzing user actions and, based on starts sorting the mail (of course you can create categories to sort). Application works smoothly, small braking when scrolling noticed only at the moment when there is synchronization. The app is counted in the list of best email apps for Android . Pros: Free; There is no limit on the number of accounts; Simple operation; Interesting feature of intellectual sorting mail and other options. Smoothly and fast. Cons: The ability to use only Google Accounts and iCloud; It takes time to get used to; it is impossible to beat in the category of writing more on some lines. 4. MailDroid MailDroid is a popular app with advertising and a large number of settings. On the first pages of the settings immediately struck by the quality of translation. Navigation is intuitive, but in my opinion not very convenient. Smooth operation is no different. MailDroid supports most popular email services, so configuration problems will not arise. Interface is made in soft blue and white, there are additional appearance settings. Default opens the folder "Inbox" in order to get to the other - need to go to a separate menu and there select the folder you want. The application has a large number of settings, it is possible to buy additional extension (for example, Spam plug-in), and it is possible to archive emails, have export / import settings and much more. Pros: Free; There is no limit on the number of accounts; Friendly controls; Many additional options / settings. Cons: Hype; Enlargement will have to re-buy for a fee; Despite the easy management interface, it seemed to me not very logical; It does not work smoothly. 5. Aqua Mail Aqua Mail is Conditionally free (free limited), very convenient mail client for Android. Free version of the application is limited - you can link only two e-mail accounts, plus all send letters added a signature with a link to the official website of the program. The full version can be unlocked for 4.95$ (the price at the beginning of 2015). The application meets us with a nice interface, something significant of the material design from Google, when you first turn on each step tooltips that help to understand the basic functions and features of the application. The interface is very smooth, good management is optimized for touch screens, is very convenient to work with a large number of letters. Working with folders organized as follows - the default application displays only one folder "Inbox", the others can be added manually (choose only those which are needed on your phone). There is an interesting feature, "Smart Folder" - to get the letters on any criteria require attention, naturally configured criteria (for example, letters received in the last X days). Pros: Convenient to work with a large number of letters; A variety of settings; A handy feature "Smart Folder"; Easy navigation; Smooth operation. Cons: The free version has some limitations. 6. CloudMagic CloudMagic is Simple e-mail client with the ability to password protection, a good alternative to the standard Android mail client. The application supports most of the international postal services. The controls are very simple, intuitive interface, it works smoothly. Folders are displayed all at once invested labeled as investment, but in the main folder, they do not collapse. Settings least of the features - the ability to enable password protection, longer any special settings there. pros: Free; There is no limit on the number of accounts; Simple and clear controls; It operates smoothly and quickly; The ability to password protect. cons: Few options / additional options.

What is strus ? The project strus is a collection of libraries and tools written in C++ to build a competitive search engine. Currently it is a single person project that started in September 2014 and therefore the competitiveness in terms of features of the software is more a promise than a fact. It definitely needs more brain to be put into it to catch up with the big players for open source search engines Lucene and Xapian. But strus is not only a me-too-project for search. Strus introduces expression matching and information extraction on a different level than other known open source engines (read more…). Strus simplifies the architecture of a search engine by “outsourcing” of components like the key/value store database storing the data blocks. This componentization (see components of strus) reduces the amount of code drastically and it raises opportunities for experts on a specific topic to contribute (read more…). Strus is not the first attempt to try that, but it is the first attempt as open source project, that has a performance within reach of the big open source search engines. And it does that without a 10 years history of optimization in the back. Strus might not be there at eye level, but let’s see what happens, if more different reasoning and competition is put into it. For who is strus ? People I would primarily like to address with this blog are developers or hackers as potential contributors or for feedback. On the other hand the project could already be interesting for experimental projects that can afford to go along with the development of strus. As stakeholder you can influence the project too. As the demo project, the search on the complete Wikipedia collection (English) shows, it is already possible to build projects, but you have to be aware, that dead lines should not exist, because you might hit a point where a feature you need is not instantaneously available. Project planning gets difficult at the current stage. Furthermore the state of documentation is still quite poor. Programming paradigms All interfaces of strus are pure. No inheritance is used in the main header files. Strus is more a lego thing than a provider of solution classes. If you want for example to build a sequence of terms as feature for your search, you have to build its expression tree with help of a stack, rather than picking a class that implements a sequence query. In PHP this looks as follows: $terms = [ “hello”, “world” ]; $query->pushTerm( “word”/*feature type*/, $term[0] ); $query->pushTerm( “word”/*feature type*/, $term[1] ); $query->pushExpression( “sequence”, 2/*nof terms*/, 2/*position range*/); $query->defineFeature( “docfeat” /*name addressing this feature set*/); The number of interface classes is small (see for example the interface classes of the core), but you have to understand them. If you want to contribute, you should also have a closer look at the programing guidelines. Try it There exist a guide how to fetch, build and install strus. Unfortunately a tutorial is still missing. There will be one soon ! Support I will reply to questions. Please mail me to contact at project dash strus dot net. Thanks I want to thank the authors of LevelDB here. I was looking for some time for a key/value store database that had an upper bound seek function in the interface. The upper bound seek is crucial because it allows you to minimize block accesses on disk when joining sets. A key/value store without upper bound seek would have forced me to create virtual blocks that point to other blocks. This would mean more disk accesses to fetch the data blocks needed. LevelDB has it. Any other alternative candidate to implement the database interface has to have it too. Social Media Github: patrickfrey Twitter: @ProjectStrus

Global Study Conducted by 451 Research Finds Skills Gap and Resource Constraints are Key Challenges for Mobile App Development; Two-Third of Mobile Apps Will be Developed Externally Over the Next Two Years London, UK. - June 23, 2015 - A new 451 Research global survey, sponsored by Kony, Inc., shows demand for new enterprise mobile applications to rapidly increase. The survey of IT management, IT development and line of business professionals found that more than half of the 480 respondents, from North America, Europe and Australia, plan to deploy 10 or more enterprise mobile apps during the next two years. However, it also revealed that IT departments are ill-equipped to meet the demand for mobile apps due to budget and resourcing limitations, skills gap, legacy infrastructure, overall technology fragmentation and immature lifecycle workflows. As a result, many companies are looking to external resources to meet business demand for mobile apps. "There is strong demand for new mobile apps, and companies are broadening their focus beyond core processes and application silos; however, enterprises are still very much in the early stages when it comes to mobile app strategies," said Chris Marsh, principal analyst, 451 Research. "IT is still in the driver's seat when it comes to both the bulk of internal mobile app development, technology procurement and project management, although line of business want input and greater collaboration. Line of business is also starting to bring a great amount of funding support to the discussion." According to the study, the types of mobile apps in highest demand by enterprises in all industries including, healthcare, financial services, insurance and retail, are customer relationship management apps for sales, marketing and services, customer engagement and general employee productivity apps. A growing proportion of companies will look to IT for the bulk of their internal mobile app development. However, the mix of development diversifies beyond just IT, with 42 percent of mobile app development work being done outside of IT. "The global market for enterprise mobility is expected to grow from $72 billion to $284 billion by 2019, nearly quadrupling in size," said Dave Shirk, president of Products and Marketing, Kony, Inc. "Companies need to be prepared to meet this demand for mobile business solutions with proper alignment between lines of business, IT developers and IT management, to effectively manage and lead enterprise mobility projects. As the largest independent provider of enterprise mobility solutions, Kony has successfully helped the world's leading enterprises to effectively use mobility as a catalyst for business innovation." Key findings from the study include: Developers need to prepare for an App-ageddon as companies look to IT for the bulk of their apps development: There will be a 25 percent increase in time spent on internal apps projects in the next two years - from 43 percent to 63 percent. The mix of development diversifies beyond just IT: IT is doing the majority (58 percent) of mobile app development work currently, while 42 percent is being done outside of IT. However, in two years, the study reveals that this figure will increase: two-thirds of apps will be developed externally - by business application vendors (21 percent), system integrators (16 percent), digital agency partners (14 percent) and developer partners (14 percent). Uncertainty of who leads mobile apps projects: The majority of developers and IT management with the enterprise are currently grappling with who has ownership of mobile projects: 55 percent of developers think they should lead mobile app projects, while 61 percent of IT management respondents said they should be leading, forcing enterprises to tear down internal barriers to align business and IT on mobile projects. Disconnect between aspirations and capabilities: Among the companies planning to build 20+ employee apps, around 60% are also planning 20+ customer and partner apps. Majority (71 percent) of these companies expect IT to be managing those app projects. Companies using mobile-specific tooling are ahead of the pack: Companies with the higher numbers of deployed apps are significantly less likely to opt for custom back-end integrations and more likely to be using mobile tools like MAPs and MBaaS. To access the full Enterprise Mobility report findings: http://forms.kony.com/rs/656-WNA-414/images/Kony-Enterprise-Mobile-App-Report.pdf For two years in a row (2013 and 2014), industry analyst firm Gartner placed Kony in the "Leaders" quadrant of the Magic Quadrant for Mobile Application Development Platforms.

if you use https to communicate with your git repository, es, github or visualstudioonline, you usually setup credential manager to avoid entering credential for each command that contact the server. with latest versions of git you can configure wincred with this simple command. git config --global credential.helper wincred this morning i start getting error while i’m trying to push some commits to github. $ git push remote: invalid username or password. fatal: authentication failed for 'https://github.com/proximosrl/jarvis.documents tore.git/' if i remove credential helper (git config –global credential.helper unset) everything works, git ask me for user name and password and i’m able to do everything, but as soon as i re-enable credential helper, the error returned. this problem is probably originated by some corruption of stored credentials, and usually you can simply clear stored credentials and at the next operation you will be prompted for credentials and everything starts worked again. the question is, where are stored credential for wincred? if you use wincred for credential.helper, git is storing your credentials in standard windows credential manager you can simply open credential manager on your computer, figure 1: credential manager in your control panel settings opening credential manager you can manage windows and web credentials. now simply have a look to both web credentials and windows credentials, and delete everything related to github or the server you are using. the next time you issue a git command that requires authentication, you will be prompted for credentials again and the credentials will be stored again in the store. gian maria.

High Wycombe, UK, 23 June 2015 The mobile POS revolution is here. Are you keeping up with the fast paced evolution?

Cost savings of up to 47% and reduced global warming potential up to 59%, says research Reading, UK. June 23rd, 2015. Ever thought about converting, rather than throwing out, your old business computers? Most businesses are used to replacing their old PCs with new ones every 3-5 years but the latest research shows that organisations can help save the planet and money by converting them to thin clients - and the savings are substantial. Businesses can cut their desktop management costs by up to 47% and reduce global warming potential by up to 59%, according to research from German scientists at the Fraunhofer Institute for Environmental, Safety and Energy Technology (UMSICHT). So how do you do it? By using a simple piece of IGEL Technology software on a USB stick or disk, old desktop computers and laptops can be converted into thin client devices in just minutes. A thin client behaves just like your old PC but stores all its information directly on the server, rather than on the device, and can be managed and updated more simply than PCs. When the researchers compared new PCs and notebooks with older devices, which continue to be used after converting them to IGEL software-based thin clients, they found that over a typical three-year period the software thin clients reduced global warming potential[1] by up to 59%, and cut overall costs by up to 47%. For a business with 100 converted computers that’s a saving of £720 per computer. Valuable contribution to protecting the climate There is also a significant saving in the greenhouse gas (CO2e) emissions. When the entire life cycle of the desktop device is taken into account from production and manufacture to distribution, operation and recycling/disposal, the institute found that the production of the devices was responsible for a high proportion of the emissions. By simply continuing to use older devices as converted thin clients it makes a significant contribution to protecting the climate since it prevents and/or defers the production of new devices. If an older PC continues to be used as a software thin client instead of a new PC being purchased, emissions fall by 198.8 kg CO2e per work station. This eco saving on one PC alone is the equivalent in emissions of driving 745 miles in a car. "This study is a revelation for businesses and public sector organisations struggling to manage with old PCs on their desktops,” said Simon Richards, IGEL Technology Managing Director for UK & Ireland. “By using a simple piece of software to convert these devices to a thin client, organisations can save significant costs, management time and help reduce their greenhouse gas emissions. In addition, this conversion of old PCs is the first simple step to moving to a virtual cloud or server-based computing infrastructure, which is much more flexible and easier to manage moving forward.” To read more about the benefits of thin client technology, visit: www.igel.co.uk [1] The global warming potential (GWP): The global warming potential (GWP) or CO2-equivalent specifies the extent to which a defined quantity of a greenhouse gas contributes to the greenhouse effect. The reference value is given in terms of carbon dioxide; the abbreviation is CO2e (for equivalent). The value represents the average warming effect over a defined timescale.

Survey of open source PostgreSQL users found adoption continues to rise with 55% of users deploying it for mission-critical applications Bedford, MA – June 23, 2015 – EnterpriseDB (EDB), the leading provider of enterprise-class Postgres products and database compatibility solutions, today announced the results of its “PostgreSQL Adoption Survey 2015,” a biennial survey of open source PostgreSQL users. Conducted by EnterpriseDB, the survey found PostgreSQL adoption continuing to rise, with 55% of users – up from 40% two years ago – deploying it for mission-critical applications and 77% of users are dedicating all new application deployments to PostgreSQL. These findings give voice to end users and confirm such industry indicators as increasing job listings and monthly rankings on DB-Engines that have pointed to rising interest in and demand for PostgreSQL, also called Postgres. The growing popularity of Postgres also comes as traditional software vendors suffer setbacks in the marketplace. The enterprise-class performance, security and stability of Postgres, on par with traditional database vendors for most corporate workloads, meanwhile have helped position Postgres among the solutions from the world’s largest vendors. The opportunity to transform their data center economics has helped fuel downloads of Postgres as well. End users reported cutting costs with Postgres, with 41% reporting they had first-year cost savings of 50% or more. They’re using Postgres to build web 2.0 applications using unstructured data as evidenced by the 64% of respondents who said they were working with JSON/JSONB and the 47% who said they were using Postgres for collaboration applications. “Postgres is empowering organizations to transform the economics of IT. IT can invest in the customer engagement applications that differentiate their operations from their competition instead of continuing to pay the steep and rising licensing and support fees charged by traditional database vendors,” said Marc Linster, senior vice president of products and services of EnterpriseDB. “With the expanding adoption, EnterpriseDB has experienced dramatic growth year over year, providing the software, services and support that organizations need to be successful with Postgres.” Database Migrations, Replacements The findings also support statements in a recent Gartner report that reflect the widespread acceptance of open source databases. “By 2018, more than 70% of new in-house applications will be developed on an OSDBMS, and 50% of existing commercial RDBMS instances will have been converted or will be in process,” according to the April 2015 Gartner report, The State of Open-Source RDBMs, 2015.* Among Postgres users, the survey findings show migrations are already under way with 37% reporting they had migrated applications from Oracle or Microsoft SQL Server to Postgres. Many users were still planning further migrations, with 37% of PostgreSQL users saying they will gradually replace their legacy systems with Postgres, compared to 29% who said that in the 2013 survey. Further, end users predict their deployments of Postgres will expand significantly, with 32% saying they anticipate production deployments of Postgres to increase by at least 50% over the next year. The survey, conducted by EnterpriseDB using an online tool in May 2015, queried registered users of PostgreSQL and drew 274 respondents worldwide from government organizations and companies ranging in size and industry. *The State of Open-Source RDBMs, 2015, by Donald Feinberg and Merv Adrian, published on April 21, 2015.

This week we're in Boston at DevNation, an awesome, young (second ever), and relatively intimate (~500 attendees) conference on anything and everything hard-core, cool-and-hot (DevOps, big data, Angular, IoT, you name it), and of course -- since the conference is organized by Red Hat -- totally open-source. So far I've had in-depth conversations with five super-amazing engineers, attended several inspiring keynotes, and chatted with one skilled developer after another. We'll transcribe the deeper interviews shortly, including some on topics totally unrelated to this post. But meanwhile I'd like to offer some thoughts inspired by the first day of the event. The general theme is: we're just beginning to get serious about separation of concerns. The metaphor that keeps popping into my head comes from the first keynote: machines have finally grown up. Imperatives: telling really unintelligent agents what to do (and then they sort of do whatever they please) It is trivial to observe that computers are incredibly stupid. Turing's fundamental paper is about how to figure out whether a theoretical computer will keep calculating the values of a function until the heat death of the universe (okay that's a slight oversimplification). The fact that Edsger Dijkstra felt the need to rail gently against all goto statements in any higher-level language than machine code suggests that, in 1968, far too many computers needed instructions about how to read the instructions that tell them what to do in the first place. Richard Feynman's famous lecture on computer heuristics is the condescension of the man who conceived quantum computing to the level of functional composition (hmmm) and file systems (double sigh). Stupid agents need to be told exactly what to do. Then they need to be told to pay attention to the exact part of the command that tells them exactly what they have been told to do (dude, just goto line 1343 already and shut up). Then they don't do what you told them (optimistically we call this an 'exception'), and then you send them into time out / set a break point and try to figure out where the idiot state muted off the rails. They stare blankly at the wall / variable / register and either do nothing or repeat another unintelligibly wrong result until you notice that your increment is (apparently meaninglessly to you) one bracket too deep. You sigh and tell them what to do again, and after a while they hit age thirty (life-years/debug-hours) and maybe do something useful with their (process-)lives. Well, maybe I'm straining the metaphor a little here, but you get the point because it cuts too close to home. We spend far too much time fixing stupid mistakes that we didn't even know we were making because -- like all actual human beings -- we assumed that the agent we commanded will use their common sense to iron out those few whiffs of, admit it, frank nonsense that our step-by-step instructions will probably always contain. So, at least, goes the imperative programming paradigm. The machine does what you tell it to; and the universe collapses onto itself before the last real number is computed. Functions: reliable, predictable adults Time to give credit where it's due: I'm really just riffing on the metaphor Venkat Subramanian offered in his highly enjoyable keynote on The Joy of Functional Programming yesterday morning His not-so-smart agents -- the 'programmed' of imperative programming -- were toddlers. Since I don't have any kids, I can't presume to understand this experience fully (although I did grow up with three younger brothers..). But the general idea is: imperative programming is tricky because, when you spell everything out super literally, it's very hard to tell exactly why what you thought should happen didn't. Venkat's talk was a whirlwind of functional concepts, from the thrill of immutability to the self-evident utility of memoization. For random (Myers-Briggs?) reasons, the object-oriented paradigm never seemed very intuitive to me -- I've gravitated towards functional style even when the problem domain wasn't actually modeled very well by functions -- but Venkat's side-by-side implementations of simple calculations in OO and functional Java showed the readability delta very clearly. Functional code is beautiful because it looks like its purpose. It tells you flat-out: here is what I do; and then it does it. But immutable functions are also beautiful because they do exactly the same thing every time. I couldn't count on my two year old brother very much at all because given a certain input I had pretty much no idea what would come out. But we all count on our grown-up collaborators to output exactly what they should, given a definite input, predictably and reliably every time. Of course, people also do more than expected -- every intervention of intelligence is an injection of creativity, not generated by the definition of the function -- but at least they do what you need them to do and no less. Containers: grown-ups with good boundaries I'm picking out just one aspect of the resurgent 'joy' of functional programming because the renaissance of containerization (another 'old' technology that is just now really taking off) is, I think, a part of the same shift toward, let's say, treating computers as adults. If functions are reliable agents, then applications in well-defined containers are self-sufficient agents who know exactly what they need from others and neither require nor demand anything more. If apps on dedicated VMs are teenagers negotiating personal boundaries by waking/booting up independently (and taking far too long -- and far too many resources -- to do so, given their meager output) -- or bubble boys, isolated in ways that are unfortunate in order to isolate in ways that are absolutely necessary -- then containerized applications are subway-riders who jam into the train without offending anyone or campers who can live anywhere with just a backpack of just the stuff they need. Of course, subway-riders and campers do more than just not-mess-up. But what's kind of neat about containers is that -- like an adult with good boundaries -- clearly defined bounds and interfaces free up the application / mind to do whatever world-changing thing the developer / human has cooked up. I'll come back to this metaphor in a later article. (Mesh networks, SDN, and ad-hoc computing are all part of the same picture, I think. Kubernetes probably is too, along with event-driven and reactive programming, the actor model, dreams of Smalltalk, and of course REST, at least of the HATEOAS flavor.) But maybe this isn't a good way to think about some of these recent sparks in devworld within a single paradigm -- and maybe my perpetual discomfort with OO is influencing me too much. What do you think?

An effective governance framework is essential for a well-managed intranet. It can be the deciding factor between a good user experience, greatly valued, and a poor user experience with little benefit. Every intranet is different depending on the size, type, and culture of the organisation it supports. However, there are some key governance principles that are common to their success. Recently I spoke at Intranatverk about this based on my book ‘Digital success or digital disaster?‘ which is a practical, experience-based approach to growing and managing a successful intranet. My slides ‘7 principles of good intranet governance’ are avilable for you to share. The alternative to governance can be chaotic anarchy. Posing risks to security and intellectual property provides an awful experience for those who still use your intranet. Where governance can start to get confusing and difficult is in how it is applied. Applying these governance principles leads to a good outcome: Know your organisation Define the scope Put people first Use all resources Compare and benchmark Do what you say you will do Keep it legal Think about how you build a house with the foundations, walls, floors, windows, doors and finally the roof. It would not make sense for you to have windows, doors, and a roof only. The same applies to your governance framework. These principles for good governance are not like a menu that you choose which items to have and leave others alone. You need to follow all of these to build a strong foundation to improve your intranet and implement your strategy. Read the introductory chapter of my new governance book to find out more. A license to share the ebook within your whole organisation is also available.

In the online community world there’s a well used heuristic that says how for every 100 members of a community, 1 will post unique content, 9 will comment on existing content, and 90 will be passive consumers. As heuristics go, it has proved relatively durable, and there is a clear motivation for community owners to attract as many of the content creators as possible. A recent study explores some of the motivations behind unique content creation, and may therefore help community managers in their quest. They have identified five core motivators behind the creation of fresh content, whether that’s a blog post, a video, song or the numerous other types of online content. Those five factors are: entertainment self-expression social-belonging communication social-cognition The five motivators were derived via the theory of uses and gratifications, together with the theory of reasoned action. These were used to better understand content creation and how we perceive such acts of creativity. The authors suggest that the five motivators behind online content creation are similar to those found in those who passively consume content online. The difference primarily lies in the area of social-cognition. This underlines our desire to share information or insights, voice our opinions online or participate in discussions. “The findings of this study would help future studies to build a more comprehensive theoretical model, which will allow scholars to understand the factors influencing consumers’ creating behavior of social media content,” the team concludes. To further muddy the waters, a study from earlier this year found that the easier we make it to create content online, the less likely people are to do so. They use an analogy of a market, with creators of content making the investment in the hope that they will attract customers (or readers). Unlike a business however, individual content creators often aren’t seeking financial reward but rather the status that comes from being heard. The larger the social network, the greater the effort required to reach people, and the authors believe it doesn’t take a huge drop-off in the ‘reward’ they receive to see the effort taken to produce content as not worthwhile. This increase in size tends to result in content that is less tailored, and therefore often less relevant to the receiver. This then often sees creators deciding that the pay-off is no longer worthwhile, whilst potential creators can be put off by the size of the market. This, the researchers believe, explains why so much content is created by so few users. Original post

[This article was written by Kevin Casey] Welcome to This Week in Modern Software, orTWiMS, New Relic’s weekly roundup of the need-to-know news, stories, and events of interest surrounding software analytics, cloud computing, application monitoring, development methodologies, programming languages, and the myriad of other issues that influence modern software. This week, our top story goes inside President Obama’s secret team of tech geeks, 140 of them and counting: TWiMS Top Story: Inside Obama’s Stealth Startup—Fast Company What it’s about:If the President of the United States walked into the room and personally recruited you to rebuild the country’s technology infrastructure, could you turn him down? He’s serious, and that room is theRoosevelt Room in the West Wing of the White House, by the way. AsLisa Gelobtersays: “What are you going to say that?” Gelobter’s answer was “Yes”—she’s now chief digital officer for the US Department of Education, part of a 140-person-and-counting tech team that’s functioning something like an elite startup embedded inside the federal government. Its business? Only modernizing the technical infrastructure, applications, and processes of just about every federal agency. Why you should care:What was once something of a tech desert—the federal government—is beginning to draw top private-sector talent inside the Beltway. The team, led by Mikey Dickerson (who helped lead the team that rescuedHealthcare.gov) andformer US CTO Todd Park, also includes the likes of former Googler Matthew Weaver, and it hopes to hit 500 people by the end 2016, shortly before President Obama will leave office. Its challenges are immense, from tackling government bureaucracy (to test just how entrenched the suits were, Weaver requested the official title “Rogue Leader”—and he got it) to the fact that its recruiting pitch includes the phrase: “You’ll have to take a pay cut.” But its mission is both noble and necessary, and the appeal of working on major problems with enormous public impacts appears to be working. Recommended reading.

Sure, that might have been part of the equation, but the rental booking site hopes open-sourcing some of its toolkit will help recruit the best software talent in the face of what director of engineeringMike Curtiscalls “insane” competition in the Silicon Valley labor market. Why you should care:In the software arms race, any little edge counts. Curtis tellsCIO Journalthat Airbnb will keep the proprietary stuff closely guarded, of course. But it will open source “generic” tools with wider industry use cases, such as its recently releasedAerosolvemachine-learning package and itsAirpalcloud-based data querying tool. The latter, which works with Facebook’s open sourcePrestoDB, aims to simplify SQL queries to the point where you don’t need to be a big data wonk or business intelligence guru to run it. Indeed, one in three Airbnb employees have run a query on it in the year since it launched. Airbnb has contributed a dozen open source tools on its aptly namedNerds site(gotta love that!) to date, something the company hopes both contributes to greater good but also advertises its software innovation to potential hires. Google Is Wielding Its Own Secret Weapon in the Cloud—The New York Times What it’s about:In thecutthroat competitionfor public cloud business, Google may be its own best customer testimonial. In advance of this week’sOpen Network Summit, theTimes’Bits bloglooked at Google’s plan to not only unveil cloud customers such as HTC but reveal much more than ever before about its own infrastructure. Google did just that on Wednesday, offering a look inside itsdata center networking, including its massive-capacity, lightning-fast Jupiter network. Why you should care:As major cloud players continue to zap prices with their shrink-rays, it’s increasingly clear that features and underlying platforms will distinguish one from the other when enterprise users make their pick. Google is taking a big step toward writing its own story in this regard, and the synopsis might read something like: “We’re pretty good at this stuff.” Its Jupiter fabrics deliver 1 petabit per second of bisection bandwidth, according to Google, or “enough for 100,000 servers to exchange information at 10Gb/s each, enough to read the entire scanned contents of the Library of Congress in less than 1/10th of a second.” If it sounds like a bit of bragging, well, yeah—it is. But it’s bragging with a purpose: Attracting devs who want access to the same technology without having to build it themselves.Google’s Amin Vahdat connected the dots in a blog post: “The same networks that power all of Google’s internal infrastructure and services also power Google Cloud Platform.” Move Over, Meeker: Byron Deeter’s State of the Cloud Report—Bessemer Venture Partners What it’s about:With a nod to Mary Meeker’s classicState of the Internet report,Bessemer Venture Partners’Byron Deeterchecks in with his 2015 State of the Cloud Report. Given cloud computing’s relative youth and rampant ascension, it’s no surprise the stats are staggering. Here’s one to start: Cloud revenues have increased tenfold in the last six years, from a scant $5.6 billion in 2008 to more than $56 billion in 2014. And it’s going to double again in the next four years, according to BVP’s projections, to $127.5 billion in 2018. Why you should care:Deeter’s full presentation is worth a weekend watch or read, but it’s the forward-looking slides that may be most compelling for software pros. Deeter notes both the immense risks and opportunities in cloud security, unveiling a 10-point security plan for cloud startups on slide 37. To underscore the security landscape, Deeter quotes an unnamed cloud CEO who says aDDoSattack that took down the firm’s API caused more customer churn in one day than in the rest of its history. Wow. He also addresses the exploding market for cloud services built specifically for developers including, yes, New Relic. And for mobile developers, slide 44 underscores something we’ve talked about before in this space:the real money’s in enterprise apps, and it’s still a largely untapped market.

Bandwidth: The Next Frontier of Cloud Computing—ZDnet What it’s about:Is networking the next big thing in the everything-as-a-service age? It just might be, as firms likePacnetvie to deliver networking capacity on a pay-for-what-you-use model that some industry folks say better suits cloud environments facing significant but uneven networking needs. Why you should care:As author Drew Turney notes, there’s a common blind spot when it comes to cloud computing’s many shapes and sizes: Moving all that data from points A to Z, and everywhere in between, which can cause both performance problems and undue financial pressures. The promise of Networking-as-a-Service (NaaS), industry execs tell Turney, is that it can provide more efficient, scalable networking for short-term usage bursts such as customer traffic spikes or large cloud backup-and-storage jobs, enabling companies to later dial down their capacity as needed. Combined withSoftware-Defined Networking (SDN),NaaS makes it possible to build intelligent applications that manage their own networking needs, which might be the most significant enterprise potential of NaaS, saysNuage NetworksarchitectMarten Hauville.
