  • Cool Enhancements Everyone Can Enjoy

    - by Ruth
    With Release 17, we have a few visual and functional enhancements that make using CRM On Demand that much better for us all. I'll mention a few here, but to get the full outline of these upgrades, I recommend taking 10 minutes to view the Release 17 Usability Transfer of Information course. First and foremost, I find the ability to customize your theme (or skin) pretty cool, but I've said that before. Take a look at the Selecting Your Theme and the Themes - Create Your CRM Style blog articles for more information. My next favorite is the resizeable user interface (UI). CRM On Demand will dynamically fit the device and screen resolution you're using, which includes the resizing of fields, field editors and pop-ups. If you have a wide screen like me, you should appreciate that one very much. To make it easier to see that resized UI, the detail pages got a little face lift. New horizontal lines and other subtle changes make those pages easier to read. Also, those things you need to know, like error messages and inline help are highlighted with a little icon to show the message type. You may not think every change to the detail pages are particularly exciting, but I'm sure you'll enjoy the new Head Up Display, which saves you scrolling time by adding links to related information sections. I like that the head up display travels with me as I move up and down the page...it's like a little friend that takes me where I want to go as fast as possible. You may also really like the fact that the copy record feature is now available for all record types from both detail pages and lists. Your company administrator can choose which fields get copied, so you can maximize your efficiency when creating new records. Lists also got a face lift. Alternating colors in rows make it easier to see your data. Also, the Favorite Lists icon is now on the list itself, so you can save your most useful lists with one click. If you've ever tried to create a new list with 10 columns or more, you'll be happy to hear that the maximum number of columns in a list has increased from 9 to 20. This is great news, but doesn't mean you should include the kitchen sink in your list...excess columns can slow list performance. So choose your columns wisely. Again, these are just a few of my favorite things. Let us know what you think about the new usability features. What are your favorite things?

  • Remote deploying wars to a liferay installation

    - by iftrue
    With vanilla tomcat, you can POST to URLs beneath SOMURL/manager/ with a proper manager user role defined. The liferay deployment of tomcat, however, is missing the manager and host-manager applications, and when I copy the directories from a vanilla Tomcat installation, I get the exception below: Exception: javax.servlet.ServletException: Error allocating a servlet instance org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:558) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) java.lang.Thread.run(Thread.java:636) root cause java.lang.SecurityException: Servlet of class org.apache.catalina.manager.HTMLManagerServlet is privileged and cannot be loaded by this web application org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:558) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) java.lang.Thread.run(Thread.java:636) What's the proper way to remote deploy wars to a liferay instance?

  • Connect to MS Sql 2008 on local VM

    - by Campo
    I have a test machine. Server 2008 with Hyper V MSSQL 2008 Enterprise Lets call it MACHINE A on the VM it is as well Server 2008 with another MSSQL 2008 Ent Call it VM B I setup a DB on MACHINE A then backed it up and restored following the prepare database for mirroring instructions on MSDN onto VM B. I used to be able to connect to the VM B Instance from the main test server (MACHINE A) but now I cannot for some reason. It cannot seem to find the instance at all even when I browse network databases. I can ping the VM from any computer on the network and access its shares so I know it is discoverable. Just the end of a long day maybe I am missing something here.

  • Mac friendly file sharing from VirtualBox

    - by kitsched
    I have set up Ruby on Rails on Ubuntu into a VirtualBox instance on my PC, I enabled Samba and I'm connecting to it via the home network from my Mac. All is fine except that I have some issues deleting some files from inside applications e.g. in Sublime Text 2 when I right click a file in the browser and select delete nothing happens (same in my Git client). To be able to delete files I have to navigate to the folder in Finder (which leaves those nasty .DS_Store files scattered all around) or issue the delete command from the terminal (inconvenient). If you're asking why I'm using VirtualBox for Rails instead of doing the development directly on the Mac it's because the ease of portability. So my question is: are there any network sharing options which I could use to make the Linux instance play nicer with my Mac?

  • Variable naming conventions?

    - by Ziv
    I've just started using ReSharper (for C#) and I kind of like its code smells finder, it shows me some things about my writing that I meant to fix a long time ago (mainly variable naming conventions). It caused me to reconsider some of my naming conventions for methods and instance variables. ReSharper suggests that instance variable be lower camel case and begin with an underscore. For a while I meant to make all my local variables lower camel case but is the underscore necessary? Do you find it comfortable? I don't like this convention but I also haven't tried it yet, what is you opinion of it? The second thing it prompted me to re-evaluate is my naming conventions for GUI event handlers. I usually use the VS standard of ControlName_Action and my controls usually use hungarian notation (as a suffix, to help clarify in code what is visible to the user and what isn't when dealing with similarly named variable) so I end up with OK_btn_Click(), what is your opinion of that? Should I succumb to the ReSharper convention or there are other equally valid options?

  • SQL SERVER – Copy Database – SQL in Sixty Seconds #067

    - by Pinal Dave
    There are multiple reasons why a user may want to make a copy of the database. Sometimes a user wants to copy the database to the same server and sometime wants to copy the database on a different server. The important point is that DBA and Developer may want copies of their database for various purposes. I copy my database for backup purpose. However, when we hear coping database – the very first thought which comes to our mind is – Backup and Restore or Attach and Detach. Both of these processes have their own advantage and disadvantages. The matter of the fact, those methods is much efficient and recommended methods. However, if you just want to copy your database as it is and do not want to go for advanced feature. You can just use the copy feature of the SQL Server. Here are the settings, which you can use to copy the database. SQL in Sixty Seconds Video I have attempted to explain the same subject in simple words over in following video. Action Item Here are the blog posts I have previously written on the subject of SA password.

  • Unity scaling instantiated GameObject at Start() doesn't "keep"

    - by Shivan Dragon
    I have a very simple scenario: A box-like Prefab which is imported from Blender automatically (I have the .blend file in the Assets folder). A script that has two public GameObject fields. In one I place the above prefab, and in the other I place a terrain object (which I've created in Unity's graphical view): public Collider terrain; public GameObject aStarCellHighlightPrefab; This script is attached to the camera. The idea is to have the Blender prefab instantiated, have the terrain set as its parent, and then scale said prefab instance up. I first did it like this, in the Start() method: void Start () { cursorPositionOnTerrain = new RaycastHit(); aStarCellHighlight = (GameObject)Instantiate(aStarCellHighlightPrefab, new Vector3(300,300,300), terrain.transform.rotation); aStarCellHighlight.name = "cellHighlight"; aStarCellHighlight.transform.parent = terrain.transform; aStarCellHighlight.transform.localScale = new Vector3(100,100,100); } and first thought it didn't work. However later I noticed that it did in fact work, in the sense where the scale was applied right at the start, but then right after the prefab instance came back to its initial scale. Putting the scale code in the Update() methods fixes it in the sense where now it stays scaled all the time: void Update () { aStarCellHighlight.transform.localScale = new Vector3(100,100,100); //... } However I've noticed that when I run this code, the object is first displayed without the scale being applied, and it takes about 5-10 seconds for the scale to happen. During this time everything works fine (like input and logging, etc). The scene is very simple, it's not like it has a lot of stuff to load or anything (there's a Ray cast from the camera on to the terrain, but that seems to happen without such delays). My (2 part) question is: Why doesn't it take the scale transform when I do it at the beginning in the Start() method. Why do I have to keep scaling it in the Update() method? Why does it take so long for the scale to "apply/show up".

  • Learning to be a good developer: what parts can you skip over?

    - by Andrew M
    I have set myself the goal of becoming a decent developer by this time next year. By this I mean full experience of the development 'lifecycle,' a few good apps/sites/webapps under my belt, and most importantly being able to work at a steady pace without getting sidelined for hours by some should-know-this-already technique. I'm not starting from scratch. I've written a lot of html/css, SQL, javascript, python and VB.net, and studied other languages like C and Java. I know about things like OOP, design patterns, TDD, complexity, computational linguistics, pointers/references, functional programming, and other academic/theoretical matters. It's just I can't say I've really done these things yet. So I want to get up to speed, and I want to know what things I can leave till a later date. For instance, studying algorithms and the maths behind them is interesting and all, but so far I've hardly needed to write anything but the most basic nested loops. Investigating Assembly to have a clearer picture of low-level operations would be cool... but I imagine rarely infringes on daily work. On the other hand, looking at a functional programming language might help me write programs that are more comprehensible and less prone to hidden failures (at the moment I'm finding the biggest difficulty is when the complexity of the app exceeds my capacity to understand it - for instance passing data around was fine... until I had to start doing it with AJAX, which was a painful step up). I could spend time working through case studies of design patterns, but I'm not sure how many of them get used in 'real life.' I'm a programmer with basic abilities - what skills should I focus on developing? (also my Unix skills are very weak, and also knowledge of Windows configuration... not sure how much time I should spend on that)

  • OSX Snow Leopard - Multiple httpd/apache instances for PHP 5.2 & 5.3 together

    - by iongion
    I need to run Apache with both php 5.2 and 5.3, without other webservers such as nginx, lighttpd, etc. Just Apache HTTPD. The easiest way to have both PHP 5.2 and PHP 5.3 on Apache, on the same machine, is to have them run in different webservers (or at least different webserver instances). I already do this on windows, it works flawlessly because it is easy to specify the conf file that a specific instance loads. But how can this be achieved on Mac OSX, without ditching the web server that OSX comes with built in ? The basic is to create N-ip addresses that each apache instance will bind to, for example: 192.168.0.52 - This is for apache httpd with PHP 5.2 192.168.0.53 - This is for apache httpd with PHP 5.3 (each apache will bind to its own ip address) On OSX, i don't know how to configure HTTPD to start as multiple service/daemon, with different startup httpd.conf files!

  • How to explain pointers to a Java/VB programmer

    - by Skeith
    I am writing a game and my friend has offered to help me as it is a RPG and will take a long time to do the "scripting" bit of the game. The problem is IMO he's not that good a programmer :( (add flame war here). He has only programmed in Java and VB and keeps saying really stupid things to me like "Why don't you drag and drop an onClick event" to design my UI when I'm using DirectX. I tried explaining pointers to him but his response was, if it's just a variable that holds a memory address, why don't you just use an int? I create an instance of an attack class and give the creature a pointer to it so if several creatures use the same attack there is only one instance of it. He keeps saying why not put if statements in the creature class for every attack class and set true for the ones that are there. He has programmed mainly in VB and a little in Java just to learn OOP. How can I explain advanced C++ concepts like pointers and memory management to him? He just doesn't understand there are no super functions like form.show in C++.

  • Unable to connect to sites using IIS7 Manager

    - by Phil.Wheeler
    I'm a developer who has been assigned the task of managing and configuring a new IIS7 instance on a remote server. My domain account has been added as to the local Administrators group on the box, but IIS7 has been configured to accept connections only from accounts with Windows credentials. I've added my domain account to the IIS Manager Permissions for one of my sites, but I'm still unable to connect to either that site, the IIS instance or the server in general from my local machine. There's obviously a missing element to the configuration of this setup but I don't know where to start looking. The event logs on the IIS box show audit failures for my account when trying to connect remote via the IIS7 Manager tool on my local machine. Suggestions gratefully received.

  • Installing SQL Server 2005 Express on Windows 8 [closed]

    - by Angel
    We have an application that installs a custom instance of Microsoft SQL Server 2005 Express as part if the whole installation process. Microsoft states that SQL Server 2005 Express is not compatible with Windows 8, but in reality it seems to install and work perfectly fine. The only problem is that during the installation a dialog appears saying it's not compatible, and offers options to get help online, continue with the installation anyway, or cancel. If you chose to continue anyway on all these incompatibility prompts, then the SQL server instance is installed without any problem whatsoever. Does anyone know if there is a way to suppress these incompatibility messages during the SQL service installation (or any installation, for that matter)?

  • Reducing latency for different geographic regions on Amazon Cloud

    - by Shoaibi
    I have got an application which has three components Application code : Amazon EC2 US-EAST-1 instance Application images, and other static data : Amazon S3 with CloudFront Application Database : Amazon RDS In short i need something like Cloud Front for EC2. In long, people using this application from a different region say middle east will have faster static content downloading due to Cloud Front but there would be a lot of latency in communicating to EC2 instance. I want to use a budget friendly way of enhancing this. Launching Amazon Instances in every region that offer is sure a choice, but isn't really cheap, so would try to avoid it unless its last resort. Also say if my clients also need to communicate to the RDS database directly, is there some kind of solution which gives that kind of functionality mentioned above, but for RDS?

  • Fabric doesn't launch Nginx remotely

    - by endofu
    I want to be able to start and stop an nginx server on an Ubuntu EC2 instance with Fabric. I have this two scripts in my fabfile.py: def start_nginx(): sudo('/etc/init.d/nginx start') #also tried this: run('sudo /etc/init.d/nginx start') def stop_nginx(): sudo('/etc/init.d/nginx stop') The start_nginx() seemingly runs without errors (* Starting Nginx Server.../ ...done.) but doesn't start the server (or it dies immediately). If I SSH into the instance this starts nginx perfectly: sudo /etc/init.d/nginx start The stop_nginx() Fabric script stops the server remotely. I compiled nginx from source, using this http://nginx.org/download/nginx-1.1.9.tar.gz and using this script in /etc/init.d: https://github.com/JasonGiedymin/nginx-init-ubuntu/blob/master/nginx. The only thing I modified is this line: DAEMON=/usr/local/sbin/nginx to DAEMON=/usr/sbin/nginx because that's the path I used when I ./configure-d my compile. Does anyone have any idea why the init script behaves differently being called from Fabric?

  • Running dnsmasq as an authoritative DNS server

    - by Lord Loh.
    I am trying to implement a dynamic dns service for my computers. I have pointed h.lohray.com to my EC2 instance in the NS record of lohray.com and have installed dnsmasq on that system and have made sure to unblock the firewall port. For now, I have statistically added an entry on my /etc/hosts file. 129.118.19.163 i7.h.lohray.com however, i7.h.lohray.com does not resolve correctly with nslookup or dig :-( This is the only time I could have this resolved (online nslookup) - 50.19.103.190 is the IP address of the EC2 instance where dnsmasq is running. Where could I have gone wrong?

  • Shared Database Servers

    - by shivanshu.upadhyay
    As more enterprises consolidate their database environments to support private cloud initiatives, ISVs will have to deal with sceanrios where they need to run on a shared powerful database server like Exadata. Some ISVs are concerned about meeting SLAs for performance in a shared environment. Outside the virtualization world, there are capabilities of Oracle Database which can be used to prevent resource contention and guarantee SLA. These capabilities are - 1) Instance Caging - This guarantees the CPU allocated or limits the maximum number of CPUs (and so the number of Oracle processes) that an instance of Database can use simultaneously. With this feature, ISVs can be assured that their application is allocated adequate CPUs even if the database server is shared with other applications. 2) CPU Resource Allocation with Database Resource Manager - This allocates percentages of CPU time to different users and applications within a database. ISVs can use this feature to ensure that priority user or workloads within their application get CPU resources over other requirements. 3) Exadata I/O Resource Manager - The Database Resource Manager feature in Oracle Database 11g has been enhanced for use with Exadata. This allows the sharing of storage between databases without fear of one database monopolizing the I/O bandwidth and impacting the performance of the other databases sharing the storage. This can be used to ensure that I/O does not become a performance bottleneck due to poor design of other applications sharing the same server.

  • Unit testing in Django

    - by acjohnson55
    I'm really struggling to write effective unit tests for a large Django project. I have reasonably good test coverage, but I've come to realize that the tests I've been writing are definitely integration/acceptance tests, not unit tests at all, and I have critical portions of my application that are not being tested effectively. I want to fix this ASAP. Here's my problem. My schema is deeply relational, and heavily time-oriented, giving my model object high internal coupling and lots of state. Many of my model methods query based on time intervals, and I've got a lot of auto_now_add going on in timestamped fields. So take a method that looks like this for example: def summary(self, startTime=None, endTime=None): # ... logic to assign a proper start and end time # if none was provided, probably using datetime.now() objects = self.related_model_set.manager_method.filter(...) return sum(object.key_method(startTime, endTime) for object in objects) How does one approach testing something like this? Here's where I am so far. It occurs to me that the unit testing objective should be given some mocked behavior by key_method on its arguments, is summary correctly filtering/aggregating to produce a correct result? Mocking datetime.now() is straightforward enough, but how can I mock out the rest of the behavior? I could use fixtures, but I've heard pros and cons of using fixtures for building my data (poor maintainability being a con that hits home for me). I could also setup my data through the ORM, but that can be limiting, because then I have to create related objects as well. And the ORM doesn't let you mess with auto_now_add fields manually. Mocking the ORM is another option, but not only is it tricky to mock deeply nested ORM methods, but the logic in the ORM code gets mocked out of the test, and mocking seems to make the test really dependent on the internals and dependencies of the function-under-test. The toughest nuts to crack seem to be the functions like this, that sit on a few layers of models and lower-level functions and are very dependent on the time, even though these functions may not be super complicated. My overall problem is that no matter how I seem to slice it, my tests are looking way more complex than the functions they are testing.

  • Reading a large SQL Errorlog

    - by steveh99999
    I came across an interesting situation recently where a SQL instance had been configured with the Audit of successful and failed logins being written to the errorlog. ie This meant… every time a user or the application connected to the SQL instance – an entry was written to the errorlog. This meant…  huge SQL Server errorlogs. Opening an errorlog in the usual way, using SQL management studio, was extremely slow… Luckily, I was able to use xp_readerrorlog to work around this – here’s some example queries..   To show errorlog entries from the currently active log, just for today :- DECLARE @now DATETIME DECLARE @midnight DATETIME SET @now = GETDATE() SET @midnight =  DATEADD(d, DATEDIFF(d, 0, getdate()), 0) EXEC xp_readerrorlog 0,1,NULL,NULL,@midnight,@now   To find out how big the current errorlog actually is, and what the earliest and most recent entries are in the errorlog :- CREATE TABLE #temp_errorlog (Logdate DATETIME, ProcessInfo VARCHAR(20),Text VARCHAR(4000)) INSERT INTO #temp_errorlog EXEC xp_readerrorlog 0 -- for current errorlog SELECT COUNT(*) AS 'Number of entries in errorlog', MIN(logdate) AS 'ErrorLog Starts', MAX(logdate) AS 'ErrorLog Ends' FROM #temp_errorlog DROP TABLE #temp_errorlog To show just DBCC history  information in the current errorlog :- EXEC xp_readerrorlog 0,1,'dbcc'   To show backup errorlog entries in the current errorlog :- CREATE TABLE #temp_errorlog (Logdate DATETIME, ProcessInfo VARCHAR(20),Text VARCHAR(4000)) INSERT INTO #temp_errorlog EXEC xp_readerrorlog 0 -- for current errorlog SELECT * from #temp_errorlog WHERE ProcessInfo = 'Backup' ORDER BY Logdate DROP TABLE #temp_errorlog XP_Errorlog is an undocumented system stored procedure – so no official Microsoft link describing the parameters it takes – however,  there’s a good blog on this here And, if you do have a problem with huge errorlogs – please consider running system stored procedure  sp_cycle_errorlog on a nightly or regular basis.  But if you do this,  remember to change the amount of errorlogs you do retain – the default of 6 might not be sufficient for you….

  • How to use private DNS to map private IP with "non registred" domain name

    - by PapelPincel
    I would like to use a private DNS (Route53 in our case) in order to map hosts to EC2 instance private IP addresse. The hosted zone we are using for testing is not declared in any registrar (company-test.com.). There are different servers (Nagios, Puppet, ActiveMQ ...) all hosted in ec2, that means their IP can change over time (restart, new instance launch...). That would be great if I can use DNS instead of clients' /etc/hosts for mapping private IP/internal domain name... The ActiveMQ server url is activemq.company-test.com and it maps to (A record) private IP address of the AMQ server. This url is only reachable by other ec2 owned by the same aws account. My question is how to configure ec2 instances so they could reach the ActiveMQ server WITHOUT having to buy a new domain company-test.com ?

  • Is it important for reflection-based serialization maintain consistent field ordering?

    - by Matchlighter
    I just finished writing a packet builder that dynamically loads data into a data stream for eventual network transmission. Each builder operates by finding fields in a given class (and its superclasses) that are marked with a @data annotation. When I finishing my implementation, I remembered that getFields() does not return results in any specific order. Should reflection-based methods for serializing arbitrary data (like my packets) attempt to preserve a specific field ordering (such as alphabetical), and if so, how?
