• Warning of "Control may reach end of non-void function"

  - by Cloud_cal

  I ran a C++ program in Xcode, and encountered a warning of "Control may reach end of non-void function". Here is the code: Node* search(Node* head, int x) { if(!head) return NULL; else if(x == head->key) return head; else if(x < head->key) search(head->lchild, x); else search(head->rchild, x); } I got the same warning when compiling it in Linux, but got the correct result. But in Xcode, the result was wrong. By the way, I got the correct answer and no warning in Visual Studio.

• Jquery mobile function calls before Ajax Request end

  - by rpmlins

  Here is my problem. When My Home page shows, I call the LoadUser functions, which on success, sets the globalUser variable with the returned json, and after it loads I call the alert function but it says globalUser is undefined. I have tried many other work arounds, but I always get the undefined mesage. If I call the alert(globalUser); on the success function, it works as expected alerting the object. $('#Home').live('pageshow', function(event) { $.when(LoadUser()).done(function(a1) { alert(globalUser); }); }); function LoadUser() { $.ajax({ // connects with the web service and validate de user input url: "http://localhost:51396/Icademy.asmx/GetUser", contentType: "application/json; charset=utf-8", data: { "userName": "'rodrigo'" }, dataType: "jsonp", success: function(json) { globalUser = JSON.parse(json.d); return globalUser; }, error: function(ret) { alert("Um erro ocorreu, tente novamente mais tarde."); } }); }

• End marker for command line arguments

  - by rwallace

  I'm writing a program which takes filenames and options on the command line in the usual way, and also can be directed to read arguments from a file. I'm implementing the semi-standard -- to turn off special treatment of subsequent arguments, and # as comment marker. I also want to implement a marker for 'disregard all arguments from here on', i.e. an end marker. Is there a common/semi-standard way to indicate this? Or, what way would people find least surprising?

• How to run a logon script but not as the current user

  - by user139951

  I want to create a log of when people login or logout of computers in a computer lab. My first idea was to just create login/logout scripts that contact a server, but the problem is since these scripts would run as the current user, that they would then be able to run this script outside of these two occasions. Is there any way to go about running a login/logout script as the domain computer rather than as the user?

• Moving the Oracle User Experience Forward with the New Release 7 Simplified UI for Oracle Sales Cloud

  - by mvaughan

  By Kathy Miedema, Oracle Applications User ExperienceIn September 2013, Release 7 for Oracle Cloud Applications became generally available for Oracle Sales Cloud and HCM Cloud. This significant release allowed the Oracle Applications User Experience (UX) team to finally talk freely about Simplified UI, a user experience project in the works since Oracle OpenWorld 2012. Simplified UI represents the direction that the Oracle user experience – for all of its enterprise applications – is heading. Oracle’s Apps UX team began by building a Simplified UI for sales representatives. You can find that today in Release 7, and it was demoed extensively during OpenWorld 2013 in San Francisco. This screenshot shows how Opportunities appear in the new Simplified UI for Oracle Sales Cloud, a user interface built for sales reps.Analyst Rebecca Wettemann, vice president of Nucleus Research, saw Simplified UI at Oracle Openworld 2013 and talked about it with CRM Buyer in “Oracle Revs Its Cloud Engines for a Better Customer Experience.” Wettemann said there are distinct themes to the latest release: "One is usability. Oracle Sales Cloud, for example, is designed to have zero training for onboarding sales reps, which it does," she explained. "It is quite impressive, actually -- the intuitive nature of the application and the design work they have done with this goal in mind."The software uses as few buttons and fields as possible, she pointed out. "The sales rep doesn't have to ask, 'what is the next step?' because she can see what it is."In fact, there are three themes driving the usability that Wettemann noted. They are simplicity, mobility, and extensibility, and we write more about them on the Usable Apps web site. These three themes embody the strategy for Oracle’s cloud applications user experiences.  Simplified UI for Oracle Sales CloudIn developing a Simplified UI for Oracle Sales Cloud, Oracle’s UX team concentrated on the tasks that sales reps need to do most frequently, and are most important. “Knowing that the majority of their work lives are spent on the road and on the go, they need to be able to quickly get in and qualify and convert their leads, monitor and progress their opportunities, update their customer and contact information, and manage their schedule,” Jeremy Ashley, Vice President of the Applications UX team, said.Ashley said the Apps UX team has a good reason for creating a Simplified UI that focuses on self-service. “Sales people spend the day selling stuff,” he said. “The only reason they use software is because the company wants to track what they’re doing.” Traditional systems of tracking that information include filling in a spreadsheet of leads or sales. Oracle wants to automate this process for the salesperson, and enable that person to keep everyone who needs to know up-to-date easily and quickly. Simplified UI addresses that problem by providing light-touch input.  “It has to be useful to the salesperson,” Ashley said about the Sales Cloud user experience. Simplified UI can tell sales reps about key opportunities, or provide information about a contact in just a click or two. Customer information is accessible quickly and easily with Simplified UI for the Oracle Sales Cloud.Simplified UI for Sales Cloud can also be extended easily, Ashley said. Users usually just need to add various business fields or create and modify analytical reports. The way that Simplified UI is constructed allows extensibility to happen by hiding or showing a few necessary fields. The Settings user interface, starting in release 7, allows for the simple configuration of the most important visual elements. “With Sales cloud, we identified a need to make the application useful and very simple,” Ashley said. Simplified UI meets that need. Where can you find out more?To find out more about the simplified UI and Oracle’s ongoing investment in applications user experience innovations, come to one of our sessions at a user group conference near you. Stay tuned to the Voice of User Experience (VoX) blog – the next post will be about Simplified UI and HCM Cloud.

• Moving a ASP.NET application to the cloud

  - by user102533

  I am new to cloud computing, so please bear with me here. I have an existing ASP.NET application with SQL Server 2008 hosted on a Virtual Private Server. Here's what it briefly does: The front end accepts user's requests and adds them to a DB table A Windows Service running in the background picks up the request, processes it and sets a flag. The Windows Services also creates a file for the user to download. User downloads file I'd like to move this web application with the service to the cloud. The architecture I envision is that I'll have 1 Web server in which I will install the front end and the windows service. I'll also have a cloud files server for file storage. The windows service should somehow create a file and transfer it to the cloud file server (I assume this is possible?) My questions: Does the architecture look like I am going in the right direction? I know Amazon has been providing cloud services for a long time. If I want to do minimal changes to my application, should I go with Amazon, Rackspace, Azure or some other provider? I understand that I would not only pay for file storage and web server but also for the bandwidth of users downloading the file and the windows servic uploading the file to the cloud server. Can I assume these costs are negligible? Should I go with VPS + Cloud Files combination to begin with? Any other thoughts/suggestions?

• least privilege account for WinRM remote calls on Windows 2008 Server

  - by aldrin

  ServerFault Windows experts: please consider the following use case: I have 2 Windows 2008 Server SP2 boxes let’s call them – SOURCE, CLIENT. On SOURCE: I create a new user called 'normal'. Just a plain user - no special privileges. On CLIENT: I run the following from a command prompt winrm get wmi/root/cimv2/Win32_UTCTime -r:SOURCE -u:normal -p:NormalPassword I get an output containing WSManFault: Message = Access is denied. On CLIENT: I repeat step 3 with the administrator identity, i.e. winrm get wmi/root/cimv2/Win32_UTCTime -r:SOURCE -u:Administrator -p:AdminPassword I get the current UTC time at SOURCE. The question is, what are the least privileges I need to assign to the user 'normal' to ensure that Step 3 behaves like Step 5. In other words, what's the least privilege to enable WinRM access for a non-Admin account?

• TortoiseSVN overlay icons do not appear when installed by a different user account?

  - by Camsoft

  I've installed TortoiseSVN on my work Windows XP machine as the administrator. When I login in as a standard user my working copies do not display the overlay icons in Windows Explorer. I found this on TortoiseSVN's support pages: Did you install TortoiseSVN as a different user under WinNT/Win2K/WinXP than you are using now? Go to the settings of TSVN and activate the icon overlays for at least the fixed drives. The installer does this automatically for the current user (can't do it for other users...) but since you are using TSVN as a different user than you installed it you need to set this manually. http://tortoisesvn.net/node/97 I've checked the settings for overlay icons for the current user and the options Local and Network drives are checked. I've tried even toggling them off, applying, then on again and applying, then restarting but they still don't appear. I'm unable to install TortoiseSVN on the current user hence why I logged into the admin account. Any ideas?

• Linux & Windows Boot Up Times in Amazon Web Service and Windows Azure

  - by Adron

  I've been working with Windows Azure and Amazon Web Services EC2 for a good many months now (almost getting to the years range) and I've seen something over and over that seems troubling. With AWS & Linux I commonly get instance startup times with EC2 around the 1-3 minute range. With AWS & Windows OS on an EC2 instance it often takes 10-20 minutes. With Windows Azure Web or Service Role I often get anywhere from 6-30 minutes waiting for a role to startup. I assume of course this involves booting up a windows instance somewhere in the fabric. I know there has always been tons of FUD about windows vs. Linux, but I'd really like to know why it is that Windows 08 or 03 boots so much slower in the cloud than Linux. Any specific technical information regarding this would be greatly appreciated! Thanks.

• Automatically Login & Startup A Windows Program On Amazon's EC2 Service

  - by darkAsPitch

  How can I automatically start a program on Amazon's EC2 Windows 2008 web servers? For example, if I wanted to test the "Digg effect" on a web page of mine, how could I open 100 windows 2008 servers at once, each loading one (or two?) instances of the firefox web browser? I have placed a sample batch file in the windows startup folder that echos the time it was called, but it is only started when I actually login remotely via the remote desktop protocol. I don't want to have to login to 100 servers to get my software to run :P What can I do? I am using this Windows 2008 Datacenter, Amazon-supplied AMI specifically: ami-a2698bcb

• Mac Management and Security

  - by Bart Silverstrim

  I was going through some literature on managing OS X laptops and asked someone some questions about usage scenarios when using the MacBooks. I asked someone more knowledgeable than I about whether it was possible for my Mac to be taken over if I were visiting another site for a conference or if I went on a wifi network at a local coffee house with policies from an OS X Server with workgroup manager (either legit for the site or someone running a version of OS X Server on hardware they have hidden somewhere on the network), which apparently could be set up to do things like limit my access to Finder or impose other neat whiz-bang management features. He said that it is indeed possible for it to happen as it would be assigned via the DHCP server and the OS X server would assume my Mac is a guest and could hand out restrictions and apparently my Mac will happily accept them without notifying me or giving me an option, unlike Windows which I believe would need to be joined to a domain before it becomes "managed" by Active Directory. So my question is as network admins and sysadmins with users traveling with MacBooks, is there a way to reasonably protect your users from having their machines hijacked without resorting to just turning off networking all the time? Or isn't this much of a security hazard? What threat does this pose to the road warriors in your businesses?

• Comparison of cloud hosting providers

  - by Abel

  Is there a place where we can compare* the many new arising cloud hosting providers? From reading into each of them, they seem very different and range from just hosting applications (google) to a semi-full enterprise web serving framework (rackspace). Comparing "by hand" takes a lot of time. All have limitations and different prizing, but which are those and how do they compare? I'm looking for an unbiased comparison site, rather then a discussion on "which is the best". * I don't mean a hosting provider comparison site, of which there are many. The properties of cloud hosting providers are remarkably different and don't compare well on classical hosting provider comparison charts.

• MySql Data Loss - post mortem analysis - RackSpace Cloud Server

  - by marfarma

  After a recent 'emergency migration' of a RS cloud server, the mysql databases on our server snapshot image proved to be days out of date from the backup date. And yet files that were uploaded through the impacted webapp had been written to the file system. Related metadata that was written to the database was lost, but the files themselves were backed-up. Once I was able to manually access the mysql data files before the mysql server started (server was configured to start mysql on boot), I was able to see that the update time for ib_logfile1, ib_logfile0 and ibdata1 was days old. As with this poster, mysql data loss after server crash, it's as if some caching controller had told the OS / mysql server that it had committed data that was still in cache, and it was lost instead of flushed. I can't quite wrap my head around how the uploaded files got written but the database data did not. I would have thought that any cache would have flushed system wide, rather than process by process. Any suggestions as to how this might have happened?

• Recommendations for distributed processing/distributed storage systems

  - by Eddie

  At my organization we have a processing and storage system spread across two dozen linux machines that handles over a petabyte of data. The system right now is very ad-hoc; processing automation and data management is handled by a collection of large perl programs on independent machines. I am looking at distributed processing and storage systems to make it easier to maintain, evenly distribute load and data with replication, and grow in disk space and compute power. The system needs to be able to handle millions of files, varying in size between 50 megabytes to 50 gigabytes. Once created, the files will not be appended to, only replaced completely if need be. The files need to be accessible via HTTP for customer download. Right now, processing is automated by perl scripts (that I have complete control over) which call a series of other programs (that I don't have control over because they are closed source) that essentially transforms one data set into another. No data mining happening here. Here is a quick list of things I am looking for: Reliability: These data must be accessible over HTTP about 99% of the time so I need something that does data replication across the cluster. Scalability: I want to be able to add more processing power and storage easily and rebalance the data on across the cluster. Distributed processing: Easy and automatic job scheduling and load balancing that fits with processing workflow I briefly described above. Data location awareness: Not strictly required but desirable. Since data and processing will be on the same set of nodes I would like the job scheduler to schedule jobs on or close to the node that the data is actually on to cut down on network traffic. Here is what I've looked at so far: Storage Management: GlusterFS: Looks really nice and easy to use but doesn't seem to have a way to figure out what node(s) a file actually resides on to supply as a hint to the job scheduler. GPFS: Seems like the gold standard of clustered filesystems. Meets most of my requirements except, like glusterfs, data location awareness. Ceph: Seems way to immature right now. Distributed processing: Sun Grid Engine: I have a lot of experience with this and it's relatively easy to use (once it is configured properly that is). But Oracle got its icy grip around it and it no longer seems very desirable. Both: Hadoop/HDFS: At first glance it looked like hadoop was perfect for my situation. Distributed storage and job scheduling and it was the only thing I found that would give me the data location awareness that I wanted. But I don't like the namename being a single point of failure. Also, I'm not really sure if the MapReduce paradigm fits the type of processing workflow that I have. It seems like you need to write all your software specifically for MapReduce instead of just using Hadoop as a generic job scheduler. OpenStack: I've done some reading on this but I'm having trouble deciding if it fits well with my problem or not. Does anyone have opinions or recommendations for technologies that would fit my problem well? Any suggestions or advise would be greatly appreciated. Thanks!

• Create an AWS HVM Linux AMI from an Existing Paravirtual Linux AMI

  - by javacavaj

  Is it possible to create a hardware virtual machine (HVM) AMI from an existing paravirtual (PV) AMI. My initially thought was to start a new PV instance and use the ec2-create-image command to create a new image while specifying HVM as the virutalization type. However, ec2-create-image does not have a command line parameter to specify the virtualization type. Is there another way to go about doing this?

• File sharing for small, distributed, non-technical, non-profit organization?

  - by mnmldave

  Problem: I've started volunteering for a small non-profit with fewer than five non-technical Windows users who need to share 20-30GB of files (Office documents, images, PDFs, etc.) amongst themselves online. Background: The users are accustomed to a Windows network share on a machine that backed up their data locally. An on-site "disaster" has forced them to work from their homes for awhile and to re-evaluate their file sharing needs (office was located in an old building with obvious electrical issues, etc.). Access to time from volunteers with IT experience seems to be difficult. Demonstrably minimizing energy consumption is a nice-to-have. I'm currently considering Jungle Disk (a Desktop account shared amongst the handful of employees since their TOS and my inquiries to their helpdesk seem to indicate this is permissible). It appears easy-to-use, inexpensive, secure, has backup functionality, and can scale to accomodate more data when needed. I've not used it myself though (have only used Dropbox for personal use) and systems isn't my area of expertise, so am worried I might be jumping on a bandwagon. That said, any suggestions, thoughts or similar experiences would be really appreciated.

• EC2 Configuration

  - by user123683

  I am trying to create a server structure for my EC2 account. The design I have chosen consists of 2 instances running in different availability zones, elastic load balancer, an auto-scaling group with cloudwatch monitoring configured and a security group defining rules for access to the instances. This setup is to support an online web application written in PHP. I am trying to decide what is a better policy: Store MySQL DB on a separate Instance Store MySQL DB on an attached EBS volume (from what i know auto-scaling will not replicate the attached EBS volume but will generate new instances from a chosen AMI - is this view correct?) Regards the AMI I plan to use a basic Amazon linux 64 bit AMI, and install bastille (maybe OSSEC) but I am looking to also use an encrypted file system. Are there any issues using an encrypted file system and communication between the DB and webapp i neeed to be aware of? Are there any comms issues using the encrypted filesystem on the instance housing the webapp I was going to launch a second instance or attach a second volume in the second availability zone to act as a standby for the database - I'm just looking for some suggestions about how to get the two DB's to talk - will this be a big task Regards updates for security is it best to create a recent snapshot and just relaunch and allow Amazon to install updates on launch or is the yum update mechanism a suitable alternative - is it better practice to relaunch instead of updates being installed which force a restart. I plan to create two AMI snapshots one for the app server and one for the DB each with the same security measures in place - is this a reasonable - I just figure it is a better policy than having additional applications that are unnecessary included in a AMI that I intend on using. My plan for backup is to create periodic snapshots of the webapp and DB instances (if I use an additional EBS volume instead of separate instances my understanding is that the EBS volume will persist in S3 storage in the event of an unexpected termination and I can create snapshots of the volume backup purposes). Thanks in advance for suggestions and advice. I am new to EC2 and I may have described unnecessary overkill but I want to try implement what can be considered a best practice solution so all advice is appreciated.

• Managing Active Directory Group Membership with a Non-Administrator Account In Server 2008

  - by Laranostz

  I am running Server 2008 R2 in an Active Directory Domain Environment. I have created a group in Active Directory and I have delegated management authority to that group to a user. I want this user to be able to add and remove accounts as needed from that group so that they are exercising some measurement of control without giving them other authority. When I have the user attempt to access the Active Directory Users & Computers Console it prompts them for Administrator credentials. They are using Remote Desktop to access the server, because they do not have Windows 7, and firewall rules prevent using the Remote Management Kit. I do not want to provide them with any level of Administrative rights except the minimum required for them to add/remove users from this group. There are two servers that 'talk' to each other in this isolated environment, a domain controller and a member server, both are only reachable through RDP. Any suggestions?
