  • How do I encapsulate the application server from the web and database servers?

    - by SNyamathi
    So I've been doing some reading and it seems like the best practice would be to have separate database, application, and web servers. There are a few things that I've failed to understand - please feel free to recommend any reading materials that would address these topics. Database (assume MySQL) Application server communication: Does the database server do any sort of checks on the SQL commands sent / returned, or is it just a "dumb pipe" that responds to SQL commands by spitting back data? Application server (assume Tomcat) Web Server Almost the reverse here, is it the web server that is more of a pipe to the internet that forwards requests to the application server and spits back responses? I'm not wording this well, but I'm trying to ask - is it the application server that is responsible for validating data received by from requests? ex: Parsing POSTs Validating user logins Encrypting decrypting data Furthermore, how do these two servers communicate? I'm trying to keep things as flexible as possible here, so while I could write a web server in Java and use Java to communicate between the web and app server, that doesn't sound very modular. What if I want to use Python or some other language to replace the web server later on? What if I want to make a non-web facing application used in house written in C++ or something.

  • How to correctly set GNU Screen to display currently running program in hardstatus

    - by johnny_bgoode
    I posted this question on SuperUser but it's hardly getting any views, so I thought I'd ask here as well. In bash, to display the name of the current program in the GNU Screen hardstatus line takes only two configuration lines. First, tell screen what the end of your prompt normally looks like, and supply a default title for a window when you are sitting at in the shell: shelltitle "$ |bash" Next, place this escape sequence in the PS1 variable, before the characters that normally terminate the prompt '$ ' in this case: \033k\033\\\ This technique works, to a point. The hardstatus window title is updated to the name of the currently running program, and then switches back to the default title shortly after execution is finished. One major problem, however, is that this escape string is not escaped itself, causing line-wrapping problems with commands longer than the initial line. This was annoying, so I set out looking for a solution. Turns out, simply escaping the previous escape sequence corrects line wrapping: [\033k]\[\033\\\] Great! My hardstatus window title still updates to the name of the currently running program, and now my longer commands wrap to the second line correctly. However, with this new escape sequence in my PS1, screen updates the window title to the actual command I am typing, not simply the name of the current program once it is executed. I am wondering, has anyone gotten this working correctly - i.e. line wrapping and proper updating of the hardstatus window title? Thanks!

  • Is there a remote desktop or vnc app for the IPad that properly handles Bluetooth keyboard shortcuts?

    - by Steve Bison
    I've tried 4 or 5 remote desktop apps, the most notable being Jump Desktop and Splashtop Streamer. Most of these remote desktop apps have some sort of on-screen keyboard for typing with the IPad, including special keys like shift, control, alt. The special keys act like "sticky keys" meaning they stay depressed until another key is pressed, to make it easier to do key combinations. Even non-standard keyboard combinations like shift+enter work, in this sticky sense. When using a Bluetooth keyboard with the remote desktop apps, both Jump and Splashtop Streamer recognize the shift + letter combination for doing capital letters. However, generically pressing shift, cntrl, or alt does not depress the sticky on screen shift buttons or do anything at all. Only a few combinations are recognized (again like shift+letter, cntrl+C). Most combinations do not work (shift+enter, alt+tab). Even having the keyboard shortcuts work like sticky keys (press shift then enter, not both at once) would be much better than the limited functionality they have now. Is there an app, jailbreak app, or workaround that lets me use bluetooth keyboard properly with remote desktop on the ipad?

  • SSH hangs when executing command remotely

    - by Serty Oan
    Client : OpenSSH_5.1p1 Debian-5ubuntu1 (Ubuntu 9.04) Server : OpenSSH_5.1p1 Debian-5 (Proxmox 2.6.24-7-pve) I use SSH to execute commands remotely on the server (module check_by_ssh of Nagios). But SSH hangs from time to time when trying to execute commands. I can log to the server via SSH but not executing a simple 'ls'. And it seems to block from all clients from the same IP address. Authentication is not the problem, may it be made by SSH keys or password. ssh -l root -p 2222 server.domain.tld 'ls' Here the client debug info debug1: Entering interactive session. debug2: callback start debug2: client_session2_setup: id 0 debug1: Sending environment. debug3: Ignored env ORBIT_SOCKETDIR *** skipping approx 40 env var ignored debug1: Sending command: ls debug2: channel 0: request exec confirm 1 It hangs there. Then after a random time, it works again (without doing anything). Killing all sshd process on the server seems to work too. It works from a Putty. I saw that some people had trouble like this due to ISP reverse DNS problem, but it does not seem to be the case here. It can work for hours and then not work for half an hour or so. What could explain this behaviour ?

  • Ways of file copy

    - by Tim
    I sometimes found that when using simple right-click and copy-and-paste, some files/directories are not copied completely or not at all, because of various reasons, such as some saved webpage files/directories have some strange characters in their names or their names are too long. For example, in Windows 7, I save this webpage http://www.howtogeek.com/howto/windows-vista/working-around-windows-vistas-shrink-volume-inadequacy-problems/ completely in a very deep directories whose parent directories may have long names, I cannot copy its top ancestry directory, as Windows complains the filename for the saved webpage directory is too long. In Ubuntu, sometimes I can save a file with some special character such as newline under some directory. But when I copy that directory, it will say the file name has some special character and I will have to manually remove the character. Such cases are complained in both Windows and Ubuntu. I was wondering what some better ways to accomplish the copy job in both Windows and Ubuntu. For example, will archiving all to be copied into a single archive help? If yes how to do that? Thanks and regards!

  • How to start MSSQL Server with corrupt model db

    - by Jordan McGuigan
    After moving some databases around (restoring, deleting, etc) we experienced an issue creating new databases. Specifically, When trying to create a new database MSSQL Server it failed because the "The database 'model' is marked RESTORING and is in a state that does not allow recovery to be run". As some online solutions suggested, we tried to Start and Stop the MSSQL Service. Service would not restart because "Could not create tempdb. You may not have enough disk space available. Free additional disk space by deleting other files on the tempdb drive" (FYI: the drive has 100gb of free space). Tried restarting the machine the MSSQL Server is running on. When the server came back online, we received the same error. We have tried deleting tempdb.mdf and restoring the modeldb from the templates folder, but neither of these solved the issue. We are unable to connect to the database, even in single user mode. Many of the online solutions have us running SQL commands against the server, but we are unable to connect (even in single user mode) to the DB to run commands against the server. Specific error messages: Database 'model' cannot be opened. It is in the middle of a restore. (Microsoft SQL Server, Error: 927) The SQL Server (MSSQLSERVER) service is starting. The SQL Server (MSSQLSERVER) service could not be started. A service specific error occurred: 1814. We need the server up and running again ASAP.

  • Using screen to monitor non-interactive scripts (or some other solution)

    - by Michael
    I have some autonomous scripts that run commands on remote machines over ssh. These scripts rely on getting stdout, stderr, and the return code of each command run. I want to be able to monitor the progress of the scripts on each target machine so that I can see if something has hung and possibly intervene if necessary. My initial idea was to have the scripts run commands in a screen session, so that the person monitoring could simply attach to the session with screen -x. However, it was hard to do that from a script since screen is an interactive program. I can send a command to the screen session with screen -S session -X stuff "command^M", but then I don't get the output and return code that I need back. My second idea was to put script /path/to/log in ~/.bash_profile and log the entire session to a file. Then the monitoring person could simply tail the log file. However, this doesn't provide the interactivity that I was looking for. Any ideas on how to solve this problem?

  • Unable to create files in a directory

    - by vamsi360
    I have created a directory in Virutalbox. Using VBoxManage, I am executing a script inside the Ubuntu VM directory I created above from Ubuntu host OS. But if the script in the VM contains commands for creating a new file, they are not executing. "echo" commands before and after the touch ommand are working fine. I even used root user for VBoxManage to install. I think the directory is not allowing the files to be created . How can I make a directory in Linux to be 777 to all new files created automatically. I mean, even if I make the directory (chmod 777 dir), I am unable to execute the script from the host. Please help. It may be simple permissions problem. Even root is unable to execute. VBoxManage guestcontrol "Ubuntu_10_04" execute --image "/bin/bash" "/home/cloudlet/Desktop/temp2/three" --username root --password root --verbose --wait-exit --wait-stdout -- -l /usr Please help. I am struggling with this problem for the past one week.

  • Compiz and Desktop Effects on Netbook with External Monitor

    - by Nerdfest
    I have an Acer Aspire One AO150 and am having trouble plugging in an external monitor under Ubuntu 9.10. There were no problems under 9.04. If I plug in an external monitor once the machine is already up, then bring up the 'display' application to activate it, it basically hangs. There are no problem under these circumstances if I have desktop effects turned off. I've seen a few mentions of this problem on the Ubuntu forums, but never a solid solution. Any ideas? A few more details after a question below. The machine does not respond to its keyboard commands to switch to an external monitor, nor does it respond to Ctrl-Alt-F1, etc to switch out of X. The pointer is visible on the monitors (at the edge of each) and is frozen as a 'busy' cursor, but with no animation. The kernel does respond to SysReq commands (REISUB). In the latest attempt I had the external monitor active earlier, then removed it and activated desktop effects. Upon plugging in the eternal monitor then bringing up the display application, it hangs.

  • Command prompt cannot find PATH variable

    - by davidXYZ
    Sometimes, my command prompt cannot find the PATH variable. I have this occasional problem at work where when I open command-prompt and run commands like ipconfig or subst, I get an error saying something like 'ipconfig' is not recognized as an internal or external command. When I try this echo %path%, it prints out %path% instead of the PATH value. If I look at my Environment Variables window, the PATH is defined right there but I don't know why CMD can't find it. At this point, I understand why the other commands were not being recognized since their paths are in PATH variable. However, I cannot understand why the PATH variable is not being found. If I restart the computer, everything is back to normal. In a few days, I might have the same experience again. I tried using this answer. It suggested changing a registry value but mine already had the value that was suggested yet it wasn't working. (The restart step at the end would have solved it as usual but that's not the point.) Any suggestions regarding why the PATH variable may become invisible every now and then and how I can prevent it from happening again?

  • Ruby on Rails: url_for :back leads to NoMethodError for back_url

    - by Platinum Azure
    Hi all, I'm trying to use url_for(:back) to create a redirect leading back to a previous page upon a user's logging in. I've had it working successfully for when the user just goes to the login page on his or her own. However, when the user is redirected to the login page due to accessing a page requiring that the user be authenticated, the redirect sends the user back to the page before the one s/he had tried to access with insufficient permissions. I'm trying to modify my login controller action to deal with the redirect properly. My plan is to have a query string parameter "redirect" that is used when a forced redirect occurs. In the controller, if that parameter exists that URL is used; otherwise, url_for(:back) is used, or if that doesn't work (due to lack of HTTP_REFERER), then the user is redirected to the site's home page. Here is the code snippet which is supposed to implement this logic: if params[:redirect] @url = params[:redirect] else @url = url_for :back @url ||= url_for :controller => "home", :action => "index" end The error I get is: NoMethodError in UsersController#login undefined method `back_url' for # RAILS_ROOT: [obscured] Application Trace | Framework Trace | Full Trace

  • I am trying to insert value from combo box to database !! but this is not working

    At first I have taken some string in which I am trying to save the input values of textboxs and there is a combo box, I am trying to save the input value of the combo box to database, but this following code is unable to do that !!! what is the prob please help me. private void OK_Click(object sender, EventArgs e) { string sTxtcmpnyName = ""; string sTxtcmpnyAdd = ""; string sPhoneno = ""; string sTxtFax = ""; string sPanNo = ""; string sTxtTin = ""; string sTax = ""; string sAccYr = ""; string sComboSt = ""; foreach (Control c in this.Controls) ////*Adding Validation to the textbox.*// // Here the control is entered into GroupBox Grpcmp where c is denoting the name of the control into the groupbox. { // c1 is another control which denotes the textboxes under the GroupBox Grpcmp. foreach (Control c1 in c.Controls) { /////Now this following code snippets reperesents that the name of the company should not be blank. if (c1 is TextBox == true) // simpler that what you've done there { TextBox temp = (TextBox)c1; //The control is entering into Txtcompany. if (temp.Name == "Txtcompanyname") { //Condition checking is the TextBox is empty or Null then the following message will be shown. if ((temp.Text == "") || (temp.Text == "NULL")) { MessageBox.Show("Company Name should not be Blank"); } sTxtcmpnyName = temp.Text; } else if (c1.Name == "TxtcompanyAddress") { sTxtcmpnyAdd = c1.Text; } else if (c1.Name == "Txtphoneno") { sPhoneno = c1.Text; } else if (c1.Name == "TxtFax ") { sTxtFax = c1.Text; } else if (c1.Name == "Txtpanno") { sPanNo = c1.Text; } else if (c1.Name == "TxtTin") { sTxtTin = c1.Text; } else if (c1.Name == "Txtservicetax") { sTax = c1.Text; } //Now I am converting the TxtAcYr into Date format. //For this purpose two conditions are checked first. //First If the TextBox TxtAcYr is Null or empty it will show the message to enter the accountyear!! //Second If the length of the TextBox TxtAcYr is less than 10, it will again generate a message The date format should be in DD/MM/YYYY // Then the value of the use input will be picked using a For loop. if (c1.Name == "TxtAcYr") { sAccYr = c1.Text; //Here a string is taken named as yearlength and the value of the TxtAcYr is assigned to it by using control c1. //Condition Checking If the TextBox TxtAcYr is Null or empty it will show the message to enter the accountyear!! if ((c1.Text == "") || (c1.Text == "NULL")) { MessageBox.Show("Account Year should be entered!!"); } //Condition 2 is checking. Here the length of the string yearlength is whether equals to 10 or not is checked. //Because there are total 10 characters in Date Format along with special character. else // MessageBox.Show(yearlength.Length.ToString()); if (sAccYr.Length != 10) { MessageBox.Show("The Data Format DD-MM-YYYY"); } //Now the value of user will be picked by using the code snippets. else { //A string named as JK is taken for further use. String JK = ""; //This following loop is initiated to pick the user input. //The loop will check wheather the value of i is less than the length of string yearlength or not. //If Yes then it will go further. for (int i = 0; i < sAccYr.Length; i++) { //This condition is checking special characters. //The positions of special characters(Here '-') are placed at 2nd and 5th numbers. //So, the value of i can not be equals to 2 && 5. if ((i != 2) && (i != 5)) { //The new of value of year length i is assinged to the variable JK.

  • Why should you choose Oracle WebLogic 12c instead of JBoss EAP 6?

    - by Ricardo Ferreira
    In this post, I will cover some technical differences between Oracle WebLogic 12c and JBoss EAP 6, which was released a couple days ago from Red Hat. This article claims to help you in the evaluation of key points that you should consider when choosing for an Java EE application server. In the following sections, I will present to you some important aspects that most customers ask us when they are seriously evaluating for an middleware infrastructure, specially if you are considering JBoss for some reason. I would suggest that you keep the following question in mind while you are reading the points: "Why should I choose JBoss instead of WebLogic?" 1) Multi Datacenter Deployment and Clustering - D/R ("Disaster & Recovery") architecture support is embedded on the WebLogic Server 12c product. JBoss EAP 6 on the other hand has no direct D/R support included, Red Hat relies on third-part tools with higher prices. When you consider a middleware solution to host your business critical application, you should worry with every architectural aspect that are related with the solution. Fail-over support is one little aspect of a truly reliable solution. If you do not worry about D/R, your solution will not be reliable. Having said that, with Red Hat and JBoss EAP 6, you have this extra cost that will increase considerably the total cost of ownership of the solution. As we commonly hear from analysts, open-source are not so cheaper when you start seeing the big picture. - WebLogic Server 12c supports advanced LAN clustering, detection of death servers and have a common alert framework. JBoss EAP 6 on the other hand has limited LAN clustering support with no server death detection. They do not generate any alerts when servers goes down (only if you buy JBoss ON which is a separated technology, but until now does not support JBoss EAP 6) and manual intervention are required when servers goes down. In most cases, admin people must rely on "kill -9", "tail -f someFile.log" and "ps ax | grep java" commands to manage failures and clustering anomalies. - WebLogic Server 12c supports the concept of Node Manager, which is a separated process that runs on the physical | virtual servers that allows extend the administration of the cluster to WebLogic managed servers that are often distributed across multiple machines and geographic locations. JBoss EAP 6 on the other hand has no equivalent technology. Whole server instances must be managed individually. - WebLogic Server 12c Node Manager supports Coherence to boost performance when managing servers. JBoss EAP 6 on the other hand has no similar technology. There is no way to coordinate JBoss and infiniband instances provided by JBoss using high throughput and low latency protocols like InfiniBand. The Node Manager feature also allows another very important feature that JBoss EAP lacks: secure the administration. When using WebLogic Node Manager, all the administration tasks are sent to the managed servers in a secure tunel protected by a certificate, which means that the transport layer that separates the WebLogic administration console from the managed servers are secured by SSL. - WebLogic Server 12c are now integrated with OTD ("Oracle Traffic Director") which is a web server technology derived from the former Sun iPlanet Web Server. This software complements the web server support offered by OHS ("Oracle HTTP Server"). Using OTD, WebLogic instances are load-balanced by a high powerful software that knows how to handle SDP ("Socket Direct Protocol") over InfiniBand, which boost performance when used with engineered systems technologies like Oracle Exalogic Elastic Cloud. JBoss EAP 6 on the other hand only offers support to Apache Web Server with custom modules created to deal with JBoss clusters, but only across standard TCP/IP networks.  2) Application and Runtime Diagnostics - WebLogic Server 12c have diagnostics capabilities embedded on the server called WLDF ("WebLogic Diagnostic Framework") so there is no need to rely on third-part tools. JBoss EAP 6 on the other hand has no diagnostics capabilities. Their only diagnostics tool is the log generated by the application server. Admin people are encouraged to analyse thousands of log lines to find out what is going on. - WebLogic Server 12c complement WLDF with JRockit MC ("Mission Control"), which provides to administrators and developers a complete insight about the JVM performance, behavior and possible bottlenecks. WebLogic Server 12c also have an classloader analysis tool embedded, and even a log analyzer tool that enables administrators and developers to view logs of multiple servers at the same time. JBoss EAP 6 on the other hand relies on third-part tools to do something similar. Again, only log searching are offered to find out whats going on. - WebLogic Server 12c offers end-to-end traceability and monitoring available through Oracle EM ("Enterprise Manager"), including monitoring of business transactions that flows through web servers, ESBs, application servers and database servers, all of this with high deep JVM analysis and diagnostics. JBoss EAP 6 on the other hand, even using JBoss ON ("Operations Network"), which is a separated technology, does not support those features. Red Hat relies on third-part tools to provide direct Oracle database traceability across JVMs. One of those tools are Oracle EM for non-Oracle middleware that manage JBoss, Tomcat, Websphere and IIS transparently. - WebLogic Server 12c with their JRockit support offers a tool called JRockit Flight Recorder, which can give developers a complete visibility of a certain period of application production monitoring with zero extra overhead. This automatic recording allows you to deep analyse threads latency, memory leaks, thread contention, resource utilization, stack overflow damages and GC ("Garbage Collection") cycles, to observe in real time stop-the-world phenomenons, generational, reference count and parallel collects and mutator threads analysis. JBoss EAP 6 don't even dream to support something similar, even because they don't have their own JVM. 3) Application Server Administration - WebLogic Server 12c offers a complete administration console complemented with scripting and macro-like recording capabilities. A single WebLogic console can managed up to hundreds of WebLogic servers belonging to the same domain. JBoss EAP 6 on the other hand has a limited console and provides a XML centric administration. JBoss, after ten years, started the development of a rudimentary centralized administration that still leave a lot of administration tasks aside, so admin people and developers must touch scripts and XML configuration files for most advanced and even simple administration tasks. This lead applications to error prone and risky deployments. Even using JBoss ON, JBoss EAP are not able to offer decent administration features for admin people which must be high skilled in JBoss internal architecture and its managing capabilities. - Oracle EM is available to manage multiple domains, databases, application servers, operating systems and virtualization, with a complete end-to-end visibility. JBoss ON does not provide management capabilities across the complete architecture, only basic monitoring. Even deployment must be done aside JBoss ON which does no integrate well with others softwares than JBoss. Until now, JBoss ON does not supports JBoss EAP 6, so even their minimal support for JBoss are not available for JBoss EAP 6 leaving customers uncovered and subject to high skilled JBoss admin people. - WebLogic Server 12c has the same administration model whatever is the topology selected by the customer. JBoss EAP 6 on the other hand differentiates between two operational models: standalone-mode and domain-mode, that are not consistent with each other. Depending on the mode used, the administration skill is different. - WebLogic Server 12c has no point-of-failures processes, and it does not need to define any specialized server. Domain model in WebLogic is available for years (at least ten years or more) and is production proven. JBoss EAP 6 on the other hand needs special processes to garantee JBoss integrity, the PC ("Process-Controller") and the HC ("Host-Controller"). Different from WebLogic, the domain model in JBoss is quite new (one year at tops) of maturity, and need to mature considerably until start doing things like WebLogic domain model does. - WebLogic Server 12c supports parallel deployment model which enables some artifacts being deployed at the same time. JBoss EAP 6 on the other hand does not have any similar feature. Every deployment are done atomically in the containers. This means that if you have a huge EAR (an EAR of 120 MB of size for instance) and deploy onto JBoss EAP 6, this EAR will take some minutes in order to starting accept thread requests. The same EAR deployed onto WebLogic Server 12c will reduce the deployment time at least in 2X compared to JBoss. 4) Support and Upgrades - WebLogic Server 12c has patch management available. JBoss EAP 6 on the other hand has no patch management available, each JBoss EAP instance should be patched manually. To achieve such feature, you need to buy a separated technology called JBoss ON ("Operations Network") that manage this type of stuff. But until now, JBoss ON does not support JBoss EAP 6 so, in practice, JBoss EAP 6 does not have this feature. - WebLogic Server 12c supports previuous WebLogic domains without any reconfiguration since its kernel is robust and mature since its creation in 1995. JBoss EAP 6 on the other hand has a proven lack of supportability between JBoss AS 4, 5, 6 and 7. Different kernels and messaging engines were implemented in JBoss stack in the last five years reveling their incapacity to create a well architected and proven middleware technology. - WebLogic Server 12c has patch prescription based on customer configuration. JBoss EAP 6 on the other hand has no such capability. People need to create ticket supports and have their installations revised by Red Hat support guys to gain some patch prescription from them. - Oracle WebLogic Server independent of the version has 8 years of support of new patches and has lifetime release of existing patches beyond that. JBoss EAP 6 on the other hand provides patches for a specific application server version up to 5 years after the release date. JBoss EAP 4 and previous versions had only 4 years. A good question that Red Hat will argue to answer is: "what happens when you find issues after year 5"?  5) RAC ("Real Application Clusters") Support - WebLogic Server 12c ships with a specific JDBC driver to leverage Oracle RAC clustering capabilities (Fast-Application-Notification, Transaction Affinity, Fast-Connection-Failover, etc). Oracle JDBC thin driver are also available. JBoss EAP 6 on the other hand ships only the standard Oracle JDBC thin driver. Load balancing with Oracle RAC are not supported. Manual intervention in case of planned or unplanned RAC downtime are necessary. In JBoss EAP 6, situation does not reestablish automatically after downtime. - WebLogic Server 12c has a feature called Active GridLink for Oracle RAC which provides up to 3X performance on OLTP applications. This seamless integration between WebLogic and Oracle database enable more value added to critical business applications leveraging their investments in Oracle database technology and Oracle middleware. JBoss EAP 6 on the other hand has no performance gains at all, even when admin people implement some kind of connection-pooling tuning. - WebLogic Server 12c also supports transaction and web session affinity to the Oracle RAC, which provides aditional gains of performance. This is particularly interesting if you are creating a reliable solution that are distributed not only in an LAN cluster, but into a different data center. JBoss EAP 6 on the other hand has no such support. 6) Standards and Technology Support - WebLogic Server 12c is fully Java EE 6 compatible and production ready since december of 2011. JBoss EAP 6 on the other hand became fully compatible with Java EE 6 only in the community version after three months, and production ready only in a few days considering that this article was written in June of 2012. Red Hat says that they are the masters of innovation and technology proliferation, but compared with Oracle and even other proprietary vendors like IBM, they historically speaking are lazy to deliver the most newest technologies and standards adherence. - Oracle is the steward of Java, driving innovation into the platform from commercial and open-source vendors. Red Hat on the other hand does not have its own JVM and relies on third-part JVMs to complete their application server offer. 95% of Red Hat customers are using Oracle HotSpot as JVM, which means that without Oracle involvement, their support are limited exclusively to the application server layer and we all know that most problems are happens in the JVM layer. - WebLogic Server 12c supports natively JDK 7, which empower developers to explore the maximum of the Java platform productivity when writing code. This feature differentiate WebLogic from others application servers (except GlassFish that are also managed by Oracle) because the usage of JDK 7 introduce such remarkable productivity features like the "try-with-resources" enhancement, catching multiple exceptions with one try block, Strings in the switch statements, JVM improvements in terms of JDBC, I/O, networking, security, concurrency and of course, the most important feature of Java 7: native support for multiple non-Java languages. More features regarding JDK 7 can be found here. JBoss EAP 6 on the other hand does not support JDK 7 officially, they comment in their community version that "Java SE 7 can be used with JBoss 7" which does not gives you any guarantees of enterprise support for JDK 7. - Oracle WebLogic Server 12c supports integration with Spring framework allowing Spring applications to use WebLogic special transaction manager, exposing bean interfaces to WebLogic MBeans to take advantage of all WebLogic monitoring and administration advantages. JBoss EAP 6 on the other hand has no special integration with Spring. In fact, Red Hat offers a suspicious package called "JBoss Web Platform" that in theory supports Spring, but in practice this package does not offers any special integration. It is just a facility for Red Hat customers to have support from both JBoss and Spring technology using the same customer support. 7) Lightweight Development - Oracle WebLogic Server 12c and Oracle GlassFish are completely integrated and can share applications without any modifications. Starting with the 12c version, WebLogic now understands natively GlassFish deployment descriptors and specific configurations in order to offer you a truly and reliable migration path from a community Java EE application server to a enterprise middleware product like WebLogic. JBoss EAP 6 on the other hand has no support to natively reuse an existing (or still in development) application from JBoss AS community server. Users of JBoss suffer of critical issues during deployment time that includes: changing the libraries and dependencies of the application, patching the DTD or XSD deployment descriptors, refactoring of the application layers due classloading issues and anomalies, rebuilding of persistence, business and web layers due issues with "usage of the certified version of an certain dependency" or "frameworks that Red Hat potentially does not recommend" etc. If you have the culture or enterprise IT directive of developing Java EE applications using community middleware to in a certain future, transition to enterprise (supported by a vendor) middleware, Oracle WebLogic plus Oracle GlassFish offers you a more sustainable solution. - WebLogic Server 12c has a very light ZIP distribution (less than 165 MB). JBoss EAP 6 ZIP size is around 130 MB, together with JBoss ON you have more 100 MB resulting in a higher download footprint. This is particularly interesting if you plan to use automated setup of application server instances (for example, to rapidly setup a development or staging environment) using Maven or Hudson. - WebLogic Server 12c has a complete integration with Maven allowing developers to setup WebLogic domains with few commands. Tasks like downloading WebLogic, installation, domain creation, data sources deployment are completely integrated. JBoss EAP 6 on the other hand has a limited offer integration with those tools.  - WebLogic Server 12c has a startup mode called WLX that turns-off EJB, JMS and JCA containers leaving enabled only the web container with Java EE 6 web profile. JBoss EAP 6 on the other hand has no such feature, you need to disable manually the containers that you do not want to use. - WebLogic Server 12c supports fastswap, which enables you to change classes without redeployment. This is particularly interesting if you are developing patches for the application that is already deployed and you do not want to redeploy the entire application. This is the same behavior that most application servers offers to JSP pages, but with WebLogic Server 12c, you have the same feature for Java classes in general. JBoss EAP 6 on the other hand has no such support. Even JBoss EAP 5 does not support this until now. 8) JMS and Messaging - WebLogic Server 12c has a proven and high scalable JMS implementation since its initial release in 1995. JBoss EAP 6 on the other hand has a still immature technology called HornetQ, which was introduced in JBoss EAP 5 replacing everything that was implemented in the previous versions. Red Hat loves to introduce new technologies across JBoss versions, playing around with customers and their investments. And when they are asked about why they have changed the implementation and caused such a mess, their answer is always: "the previous implementation was inadequate and not aligned with the community strategy so we are creating a new a improved one". This Red Hat practice leads to uncomfortable investments that in a near future (sometimes less than a year) will be affected in someway. - WebLogic Server 12c has troubleshooting and monitoring features included on the WebLogic console and WLDF. JBoss EAP 6 on the other hand has no direct monitoring on the console, activity is reflected only on the logs, no debug logs available in case of JMS issues. - WebLogic Server 12c has extremely good performance and scalability. JBoss EAP 6 on the other hand has a JMS storage mechanism relying on Oracle database or MySQL. This means that if an issue in production happens and Red Hat affirms that an performance issue is happening due to database problems, they will not support you on the performance issue. They will orient you to call Oracle instead. - WebLogic Server 12c supports messaging enterprise features like SAF ("Store and Forward"), Distributed Queues/Topics and Foreign JMS providers support that leverage JMS implementations without compromise developer code making things completely transparent. JBoss EAP 6 on the other hand do not even dream to support such features. 9) Caching and Grid - Coherence, which is the leading and most mature data grid technology from Oracle, is available since early 2000 and was integrated with WebLogic in 2009. Coherence and WebLogic clusters can be both managed from WebLogic administrative console. Even Node Manager supports Coherence. JBoss on the other hand discontinued JBoss Cache, which was their caching implementation just like they did with the messaging implementation (JBossMQ) which was a issue for long term customers. JBoss EAP 6 ships InfiniSpan version 1.0 which is immature and lack a proven record of successful cases and reliability. - WebLogic Server 12c has a feature called ActiveCache which uses Coherence to, without any code changes, replicate HTTP sessions from both WebLogic and other application servers like JBoss, Tomcat, Websphere, GlassFish and even Microsoft IIS. JBoss EAP 6 on the other hand does have such support and even when they do in the future, they probably will support only their own application server. - Coherence can be used to manage both L1 and L2 cache levels, providing support to Oracle TopLink and others JPA compliant implementations, even Hibernate. JBoss EAP 6 and Infinispan on the other hand supports only Hibernate. And most important of all: Infinispan does not have any successful case of L1 or L2 caching level support using Hibernate, which lead us to reflect about its viability. 10) Performance - WebLogic Server 12c is certified with Oracle Exalogic Elastic Cloud and can run unchanged applications at this engineered system. This approach can benefit customers from Exalogic optimization's of both kernel and JVM layers to boost performance in terms of 10X for web, OLTP, JMS and grid applications. JBoss EAP 6 on the other hand has no investment on engineered systems: customers do not have the choice to deploy on a Java ultra fast system if their project becomes relevant and performance issues are detected. - WebLogic Server 12c maintains a performance gain across each new release: starting on WebLogic 5.1, the overall performance gain has been close to 4X, which close to a 20% gain release by release. JBoss on the other hand does not provide SPECJAppServer or SPECJEnterprise performance benchmarks. Their so called "performance gains" remains hidden in their customer environments, which lead us to think if it is true or not since we will never get access to those environments. - WebLogic Server 12c has industry performance benchmarks with submissions across platforms and configurations leading SPECJ. Oracle WebLogic leads SPECJAppServer performance in multiple categories, fitting all customer topologies like: dual-node, single-node, multi-node and multi-node with RAC. JBoss... again, does not provide any SPECJAppServer performance benchmarks. - WebLogic Server 12c has a feature called work manager which allows your application to embrace new performance levels based on critical resource utilization of the CPUs usage. Work managers prioritizes work and allocates threads based on an execution model that takes into account administrator-defined parameters and actual run-time performance and throughput. JBoss EAP 6 on the other hand has no compared feature and probably they never will. Not supporting such feature like work managers, JBoss EAP 6 forces admin people and specially developers to uncover performance gains in a intrusive way, rewriting the code and doing performance refactorings. 11) Professional Services Support - WebLogic Server 12c and any other technology sold by Oracle give customers the possibility of hire OCS ("Oracle Consulting Services") to manage critical scenarios, deployment assistance of new applications, high skilled consultancy of architecture, best practices and people allocation together with customer teams. All OCS services are available without any restrictions, having the customer bought software from Oracle or just starting their implementation before any acquisition. JBoss EAP 6 or Red Hat to be more specifically, only offers professional services if you buy subscriptions from them. If you are developing a new critical application for your business and need the help of Red Hat for a serious issue or architecture decision, they will probably say: "OK... I can help you but after you buy subscriptions from me". Red Hat also does not allows their professional services consultants to manage environments that uses community based software. They will probably force you to first buy a subscription, download their "enterprise" version and them, optionally hire their consultants. - Oracle provides you our university to educate your team into our technologies, including of course specialized trainings of WebLogic application server. At any time and location, you can hire Oracle to train your team so you get trustful knowledge according to your specific needs. Certifications for the products are also available if your technical people desire to differentiate themselves as professionals. Red Hat on the other hand have a limited pool of resources to train your team in their technologies. Basically they are selling training and certification for RHEL ("Red Hat Enterprise Linux") but if you demand more specialized training in JBoss middleware, they will probably connect you to some "certified" partner localized training since they are apparently discontinuing their education center, at least here in Brazil. They were not able to reproduce their success with RHEL education to their middleware division since they need first sell the subscriptions to after gives you specialized training. And again, they only offer you specialized training based on their enterprise version (EAP in the case of JBoss) which means that the courses will be a quite outdated. There are reports of developers that took official training's from Red Hat at this year (2012) and in a certain JBoss advanced course, Red Hat supposedly covered JBossMQ as the messaging subsystem, and even the printed material provided was based on JBossMQ since the training was created for JBoss EAP 4.3. 12) Encouraging Transparency without Ulterior Motives - WebLogic Server 12c like any other software from Oracle can be downloaded any time from anywhere, you should only possess an OTN ("Oracle Technology Network") credential and you can download any enterprise software how many times you want. And is not some kind of "trial" version. It is the official binaries that will be running for ever in your data center. Oracle does not encourages the usage of "specific versions" of our software. The binaries you buy from Oracle are the same binaries anyone in the world could download and use for testing and personal education. JBoss EAP 6 on the other hand are not available for download unless you buy a subscription and get access to the Red Hat enterprise repositories. If you need to test, learn or just start creating your application using Red Hat's middleware software, you should download it from the community website. You are not allowed to download the enterprise version that, according to Red Hat are more secure, reliable and robust. But no one of us want to start the development of a software with an unsecured, unreliable and not scalable middleware right? So what you do? You are "invited" by Red Hat to buy subscriptions from them to get access to the "cool" version of the software. - WebLogic Server 12c prices are publicly available in the Oracle website. If you want to know right now how much WebLogic will cost to your organization, just click here and get access to our price list. In the case of WebLogic, check out the "US Oracle Technology Commercial Price List". Oracle also encourages you to get in touch with a sales representative to discuss discounts that would make possible the investment into our technology. But you are not required to do this, only if you are interested in buying our technology or maybe you want to discuss some discount scenarios. JBoss EAP 6 on the other hand does not have its cost publicly available in Red Hat's website or in any other media, at least is not so easy to get such information. The only link you will possibly find in their website is a "Contact a Sales Representative" link. This is not a very good relationship between an customer and an vendor. This is not an example of transparency, mainly when the software are sold as open. In this situations, customers expects to see the software prices publicly available, so they can have the chance to decide, based on the existing features of the software, if the cost is fair or not. Conclusion Oracle WebLogic is the most mature, secure, reliable and scalable Java EE application server of the market, and have a proven record of success around the globe to prove it's majority. Don't lose the chance to discover today how WebLogic could fit your needs and sustain your global IT middleware strategy, no matter if your strategy are completely based on the Cloud or not.

  • how get validation messages from mangomapper using rails console ?

    - by Alex
    Hi, I am basically teaching myself how to use RoR and MongoDB at the same time. I am following the very good book / tutorial : http://railstutorial.org/ I decided to replace Sqlite3 by MongoDB using the mongomapper gem. Everything works out about alright, but I am having some non-blocking little issues that I truly wish I could get rid of. In chapter 6, when working with validation I got 2 issues: - I don't know how to get the validations messages back like with Sqlite3. The "standard" code is: $ rails console --sandbox >> user = User.new(:name => "", :email => "[email protected]") >> user.save => false >> user.valid? => false >> user.errors.full_messages => ["Name can't be blank"] but if I try to do the same with MongoMapper, it throws an error saying that errors is undefined function. So does it mean that this is simply not implemented in mongomapper / mongo driver ? Or is there some other clever way to do this that I could not figure ? Additional, 2 things here: - I following the exemple in the book to the line, so I was expecting to be able to use the console in sandbox mode, but apparently that does not work either: (...)ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/console/sandbox.rb:1:in `<top (required)>': uninitialized constant ActiveRecord (NameError) from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/application.rb:226:in `initialize_console' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/application.rb:153:in `load_console' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands/console.rb:26:in `start' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands/console.rb:8:in `start' from /Users/Alex/.rvm/gems/ruby-1.9.2-p136@rails3/gems/railties-3.0.3/lib/rails/commands.rb:23:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>' Also, in the book they call "user" but I need to call "User" (note the capital U) why is that ? Is it like mangomapper does not follow the Ruby naming convention or something ? And finally, I am trying to validate the field email with a regex as shown in the tutorial. It does not throws any errors at the code, but whenever I try to insert it just won't ever accept it unless I comment out the :format option... class User include MongoMapper::Document key :name, String, :required => true, :length => { :maximum => 50 } key :email, String, :required => true, # :format => { :with => email_regex }, :uniqueness => { :case_sentitive => false} timestamps! end Any advices you can provide on those topics would help me a lot ! Thanks, Alex

  • Making Thunar the default file browser without hiding the desktop icons

    - by Manu
    I really dislike Ubuntu's default file browser, nautilus, and decided to opt for a lighter alternative (Thunar or Xfe). I've used the following script to change the default to Thunar, but now all my icons are gone from the desktop ! The files are still there, in /home/myid/Desktop, but they do not appear. Is there a way to show them, or is this a consequence of removing nautilus as the default file browser ?

  • Overwrite archetypes in Maven

    - by Random
    Hello again! I'm having some trouble using Maven for my archetypes and I will need to overwrite some. I launch an instruction that does an archetype:generate in an archetype already existing directory. Is there a parameter that let's me overwrite existing archetypes? I have search the maven definitve guide but it states that the only parameters accepted are: -DgroupId -DartifactId -Dversion -DpackageName -DarchetypeGroupId -DarchetypeArtifactId -DarchetypeVersion -DinteractiveMode I could just search the directory and delete the files, but this proccess is going to be done automatically (so no human involved, no brains involved) and I wouldn't like he machine deleting things around.

  • ObjectContext.SaveChanges() fails with SQL CE

    - by David Veeneman
    I am creating a model-first Entity Framework 4 app that uses SQL CE as its data store. All is well until I call ObjectContext.SaveChanges() to save changes to the entities in the model. At that point, SaveChanges() throws a System.Data.UpdateException, with an inner exception message that reads as follows: Server-generated keys and server-generated values are not supported by SQL Server Compact. I am completely puzzled by this message. Any idea what is going on and how to fix it? Thanks. Here is the Exception dump: System.Data.UpdateException was unhandled Message=An error occurred while updating the entries. See the inner exception for details.

  • Flatten XML using XSLT but based on nesting level

    - by user2532750
    I'm new to XSLT and I'm trying to write some XSLT that will flatten any given XML such that a new line occurs whenever the nesting level changes. My input can be any XML document, with any number of nested levels so the structure isn't known to the XSLT. Due to the tools available to me, my solution has to use XSLT version 1.0. For example. <?xml version="1.0"?> <ROWSET> <ROW> <CUSTOMER_ID>0</CUSTOMER_ID> <NAME>Default Company</NAME> <BONUSES> <BONUSES_ROW> <BONUS_ID>21</BONUS_ID> <DESCRIPTION>Performance Bonus</DESCRIPTION> </BONUSES_ROW> <BONUSES_ROW> <BONUS_ID>26</BONUS_ID> <DESCRIPTION>Special Bonus</DESCRIPTION> </BONUSES_ROW> </BONUSES> </ROW> <ROW> <CUSTOMER_ID>1</CUSTOMER_ID> <NAME>Dealer 1</NAME> <BONUSES> <BONUSES_ROW> <BONUS_ID>27</BONUS_ID> <DESCRIPTION>June Bonus</DESCRIPTION> <BONUS_VALUES> <BONUS_VALUES_ROW> <VALUE>10</VALUE> <PERCENT>N</PERCENT> </BONUS_VALUES_ROW> <BONUS_VALUES_ROW> <VALUE>11</VALUE> <PERCENT>Y</PERCENT> </BONUS_VALUES_ROW> </BONUS_VALUES> </BONUSES_ROW> </BONUSES> </ROW> <ROWSET> needs to becomes.... 0, Default Company 21, Performance Bonus 26, Special Bonus 1, Dealer 1 27, June Bonus 10, N 11, Y The XSLT I've written so far is... <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text" encoding="iso-8859-1"/> <xsl:strip-space elements="*" /> <xsl:template match="/*/child::*"> <xsl:apply-templates select="*"/> </xsl:template> <xsl:template match="*"> <xsl:value-of select="text()" /> <xsl:if test="position()!= last()"><xsl:text>,</xsl:text></xsl:if> <xsl:if test="position()= last()"><xsl:text>&#xD;</xsl:text></xsl:if> <xsl:apply-templates select="./child::*"/> </xsl:template> </xsl:stylesheet> but my output just isn't correct, with gaps and unnecessary data. 0,Default Company, ,21,Performance Bonus 26,Special Bonus 1,Dealer 1, 27,June Bonus, ,10,N 11,Y It seems there needs to be a check as whether or not a node can contain text, but I'm stuck and could do with an XSLT expert's help.

  • com.sun.org.apache.xerces.internal.dom.DocumentImpl cannot be cast to org.codehaus.plexus.util.xml.X

    - by Random
    Afetr using the Model library (see this) for my Maven pom.xml during this weeks I jumped on this error while attempting to write a ConfiguratonContainer into the pom.xml. The javadoc for Model says: public void setConfiguration(Object configuration) Set the configuration as DOM object. Parameters: configuration - So I made some xml with Document (org.w3c.dom.Document) and the xml parser standar javax library. You know the code (it's through all the net) but I paste it here... DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder parser = factory.newDocumentBuilder(); Document doc =parser.newDocument(); And then you fill the code with Element declaration,a lot of appendChild and such. And tried to make it work. Doesn't seem to do well. First tried using plugin.setConfiguration(doc); But it didn't work. Then I tried Obejct obj = doc; plugin.setConfiguration(obj); But it didn't work. Then I searched the net for answers, and guess... It didn't work. There are like 0 people using this library (maven.model) in all the net. So here am I again, asking the senseis for help. Where is my error? I have downloaded the source code of the library trying to see where is the error, but it seems to be ok (as should).

  • Form inside a hidden div has no values on post

    - by Mick
    I have a html form that posts to a new page on submit. If required a user can click a button to make a small table visible in a div box. this adds more text input fields to my form. The problem is, regardless of the div box being hidden or visible none of the additional fields data is sent when the form is posted . the div box code function quotevisi() { document.getElementById("quote").style.visibility = "visible"; tdat = "" ; tdat += "<h2 align='center' >Client Quotation </h2>" ; tdat += "<table align='center'cellpadding='1' width='690px'><tr>" tdat += "<td ></td><td>Additional 1</td>" ; tdat += "<td ><label><textarea id='line1' cols='50' rows='1'>" tdat += "</textarea></label></td></tr>" tdat += "<td ></td><td >Additional 2 </td>" ; tdat += "<td ><label><textarea id='line2' name='line2' cols='50' rows='1'>" tdat += "</textarea></label></td></tr>" tdat += "<td ></td><td >Additional 3 </td>" ; tdat += "<td ><label><textarea id='line3' name='line3' cols='50' rows='1'>" tdat += "</textarea></label></td></tr>" tdat += "<td ></td><td >Special Instructions</td>" ; tdat += "<td ><label><textarea id='special' name='special' cols='50' rows='1'>" tdat += "</textarea></label></td></tr>" tdat += "<td ></td><td ></td> <td>" ; tdat += "<input type='button' value='View Quote' onclick='view_quote()' /> " tdat += "<input type='button' value='Close' onclick='closequote()' /> " tdat += "<td ></td> " ; tdat += "</table> " // display in the quote div (style sheet) document.getElementById('quote').innerHTML= tdat } The form is a bit big to but the button for the hidden field is this <td ><input class="buttn" type="button" value="Extra Quote details " onclick="quotevisi();" /> </td> I would of thought that all this information would go with the form on post . But it doesent. Oh finally the div box code is placed after this line <form style='background-color:ccc' id='form1' name='form1' method='post' action='process.php' > Any help or thoughts would be much appreciated thanks Mick

  • MSCC: Purpose and benefits of Version Control Systems (VCS)

    Unfortunately, there was no monthly meetup during May. Which means that it was even more important and interesting to go forward with a great topic for this month. Earlier this year I already spoke to Nayar Joolfoo about doing a presentation on version control systems (VCS), and he gladly agreed since then. It was just about finding the right date for the action. Furthermore, it was also a great coincidence that Avinash Meetoo announced on social media networks that Knowledge 7 is about to have a new training on "Effective git" - which correlates to a book title Avinash is currently working on - all the best with your approach on this and reach out to our MSCC craftsmen for recessions. Once again a big Thank you to Orange Ebene Accelerator on providing the venue for us, and the MSCC members involved on securing the time slot for our event. Unfortunately, it's kind of tough to get an early confirmation for our meetups these days. I'll keep you posted on that one as there are some interesting and exciting options coming up soon. Okay, let's talk about the meeting and version control systems again. As usual, I'm going to put my first impression of the meetup: "Absolutely great topic, questions and discussions on version control systems, like git or VSO. I was also highly pleased by the number of first timers and female IT geeks. Hopefully, we will be able to keep this trend for future get-togethers." And I really have to emphasise the amount of fresh blood coming to our gathering. Also, during the initial phase it was surprising to see that exactly those first-timers, most of them students at various campuses here on the island, had absolutely no idea about version control systems. More about further down... Reactions of other attendees If I counted correctly, we had a total of 17 attendees this month, and I'd like to give you feedback from some of them: "Inspiring. Helped me understand more about GIT." -- Sean on event comments "Joined the meetup today with literally no idea what is a version control system. I have several reasons why I should be starting to use VCS as from NOW in my projects. Thanks Nayar, Jochen and other participants :)" -- Yudish on event comments "Was present today and I'm very satisfied.I was not aware if there was a such tool like git available. Thanks to those who contributed for this meetup.It was great. Learned a lot from this meetup!!" -- Leonardo on event comments "Seriously, I can see how it’s going to ease my task and help me save time. Gone are the issues with files backups.  And since I’ll be doing my dissertation this year, using Git would help me a lot for my backups and I’m grateful to Nayar for the great explanation." -- Swan-Iyah on MSCC meetup : Version Controls Hopefully, I'll be able to get some other sources - personal blogs preferred - on our meeting. Geeks, thank you so much for those encouraging comments. It's really great to experience that we, all members of the MSCC, are doing the right thing to get more IT information out, and to help each other to improve and evolve in our professional careers. Our agenda of the day Honestly, we had a bumpy start... First, I was battling a little bit with the movable room divider in order to maximize the space. I mean, we had 24 RSVPs and usually there might additional people coming along. Then, for what ever reason, we were facing power outages - actually twice in short periods. Not too good for the projector after all, but hey it went smooth for the rest of the time being. And last but not least... our first speaker Nayar got stuck somewhere on the road. ;-) Anyway, not a real show-stopper and we used the time until Nayar's arrival to introduce ourselves a little bit. It is always important for me to get to know the "newbies" a little bit, and as a result we had lots of students of university - first year, second year and recent graduates - among them. Surprisingly, none of them was ever in contact with version control systems at all. I mean, this is a shocking discovery! Similar to the ability of touch-typing I'd say that being able to use (and master) any kind of version control system is compulsory in any job in the IT industry. Seriously, I'm wondering what is being taught during the classes on the campus. All of them have to work on semester assessments or final projects, even in small teams of 2-4 people. That's the perfect occasion to get started with VCS. Already in this phase, we had great input from more experienced VCS users, like Sean, Avinash and myself. git - a modern approach to VCS - Nayar What a tour! Nayar gave us the full round of git from start to finish, even touching some more advanced techniques. First, he started to explain about the importance of version control systems as an essential tool for software developers, even working alone on a project, and the ability to have a kind of "time machine" that allows you to inspect and revert to a previous version of source code at any time. Then he showed how easy it is to install git on an Ubuntu based system but also mentioned that git is literally available for any operating system, like Windows, Mac OS X and of course other Linux distributions. Next, he showed us how to set the initial configuration values of user name and email address which simplifies the daily usage of the git client while working with your repositories. Then he initialised and added a new repository for some local development of a blogging software. All commands were done using the command line interface (CLI) so that they can be repeated on any system as reference. The syntax and the procedure is always the same, and Nayar clearly mentioned this to the attendees. Now, having a git repository in place it was about time to work on some "important" changes on the blogging software - just for the sake of demonstrating the ease of use and power of git. One interesting question came very early: "How many commands do we have to learn? It looks quite difficult at the moment" - Well, rest assured that during daily development circles you will need less than 10 git commands on a regular base: git add, commit, push, pull, checkout, and merge And Nayar demo'd all of them. Much to the delight of everyone he also showed gitk which is the git repository browser. It's an UI tool to display changes in a repository or a selected set of commits. This includes visualizing the commit graph, showing information related to each commit, and the files in the trees of each revision. Using gitk to display and browse information of a local git repository And last but not least, we took advantage of the internet connectivity and reached out to various online portals offering git hosting for free. Nayar showed us how to push the local repository into a remote system on github. Showing the web-based git browser and history handling, and then also explained and demo'd on how to connect to existing online repositories in order to get access to either your own source code or other people's open source projects. Next to github, we also spoke about bitbucket and gitlab as potential online platforms for your projects. Have a look at the conditions and details about their free service packages and what you can get additionally as a paying customer. Usually, you already get a lot of services for up to five users for free but there might be other important aspects that might have an impact on your decision. Anyways, moving git-based repositories between systems is a piece of cake, and changing online platforms is possible at any stage of your development. Visual Studio Online (VSO) - Jochen Well, Nayar literally covered all elements of working with git during his session, including the use of external online platforms. So, what would be the advantage of talking about Visual Studio Online (VSO)? First of all, VSO is "just another" online platform for hosting and managing git repositories on remote systems, equivalent to github, bitbucket, or any other web site. At the moment (of writing), Microsoft also provides a free package of up to five users / developers on a git repository but there is more in that package. Of course, it is related to software development on the Windows systems and the bonds are tightened towards the use of Visual Studio but out of experience you are absolutely not restricted to that. Connecting a Linux or Mac OS X machine with a git client or an integrated development environment (IDE) like Eclipse or Xcode works as smooth as expected. So, why should one opt in for VSO? Well, one of the main aspects that I would like to mention here is that VSO integrates the Application Life Cycle Methodology (ALM) of Microsoft in their platform. Meaning that you get agile project management with Backlogs, Sprints, Burn-down charts as well as the ability to track tasks, bug reports and work items next to collaborative team chats. It's the whole package of agile development you'll get. And, something I mentioned briefly during the begin of our meeting, VSO gives you the possibility of an automated continuous integrated (CI) process which builds and can run tests of your source code after each commit of changes. Having a proper CI strategy is also part of the Clean Code Developer practices - on Level Green actually -, and not only simplifies your life as a software developer but also reduces the sources of potential errors. Seamless integration and automated deployment between Microsoft Azure Web Sites and git repository But my favourite feature is the seamless continuous deployment to Microsoft Azure. Especially, while working on web projects it's absolutely astounishing that as soon as you commit your chances it just takes a couple of seconds until your modifications are deployed and available on your Azure-hosted web sites. Upcoming Events and networking Due to the adjusted times, everybody was kind of hungry and we didn't follow up on networking or upcoming events - very unfortunate to my opinion and this will have an impact on future planning of our meetups. Because I rather would like to see more conversations during and at the end of our meetings than everyone just packing their laptops, bags and accessories and rush off to grab some food. I was hoping to get some information regarding this year's Code Challenge - supposedly to be organised during July? Maybe someone could leave a comment on that - but I couldn't get any updates. Well, I'll keep digging... In case that you would like to get more into git and how to use it effectively, please check out Knowledge 7's upcoming course on "Effective git". Thanks Avinash for your vital input into today's conversation and I'm looking forward to get a grip on your book title very soon. My resume of the day Do not work in IT without any kind of version control system! Seriously, without a VCS in place you're doing it wrong. It's like driving a car without seat belts attached or riding your bike without safety helmet. You don't do that! End of discussion. ;-) Nowadays, having access to free (as in cost) tools to install on your machine and numerous online platforms to host your source code for free for up to five users it's a no-brainer to get yourself familiar with VCS. Today's sessions gave a good overview on how to start using git and how to connect to various remote services like github or VSO.
