• NetBeans Platform Unit Test Library Dependencies

  - by Ben Hammond

  I am working on a Netbeans Platform RCP application. I use jmock in my unit tests and I have created a Library Wrapper Module to import the necessary libraries. The Module has an section named 'Libraries' and another section named 'Unit Test Libraries'. I hoped that I could add the JMock Library Wrapper to the 'Unit Test Libraries', however when I run the unit tests I get the error 'package org.jmock does not exist'. If I import the JMock Library Wrapper in to the main 'Libraries' element then it works, but this feels wrong. Maven allows me to specify unit-test only dependencies, and I assumed that NetBeans Platform did the same. Should this be possible? Am I doing something wrong? Should I resign myself to a run-time dependency on the unit-test libraries (ugh).

• DllImport Based on OS Platform

  - by Ngu Soon Hui

  I have a mixture of unmanaged code ( backend) and managed code ( front end), as such, I would need to call the unmanaged code from my managed code, using interop techniques and DllImport attribute. Now, I've compiled two versions of unmanaged code, for both 32 and 64 bit OS; they are named service32.dll and service64.dll respectively. So, in my .Net code, I would have to do a DllImport for both dlls: [DllImport(@"service32.dll")] //for 32 bit OS invocation public static void SimpleFunction(); [DllImport(@"service64.dll")] //for 64 bit OS invocation public static void SimpleFunction(); And call them depending on which platform my application is running on. The issue now is that for every unmanaged function, I have to declared it twice, one for 32 bit OS and one for 64 bit OS. This is a duplication of work, and everytime I change the signature of an unmanaged function, I have to modified it in two places. Is there anyway that I can change the argument in DllImport so that the correct dll will be invoked automagically, depending on the platform?

• Which is the UI technology of the future considering: eye-candy-effect, interactivity (gestures, voc

  - by user193655

  If you had to write a next-gen application, in which on the surface (UI) you need some "futuristic features", by considering the following aspects which is the choice you'd make? 1) eye-candy: cool UI, 3D, Effects, nice graphics, sound transitions... 2) user interaction: not only mouse and keyboard but touch, voice and more.... + user interactivity aspect, which is the technology you'd choose? 3) X-platform: this is to have some X-platform discussion. Of course single platform technologies (as WPF) have may be some more power, anyway in a general discussion considering X-platform as a resource is important 4) available components: of course the coolest technology with no available components is may be an option for a component developer but not for an application developer My question is generic, but anyway * have in mind data-driven apps, not pure multimedia apps, videogames, ....

• Book resources for x86/x64 assembly programming on Win platform

  - by Scott Davies

  Hello, I ran a search for assembly language resources on stackoverflow.com and found some interesting results, but they seemed to boil down to two groups: 1) Assembly references to old ia32 architecture, such as the 80386 to Pentium 2) Windows agnostic books. Most of the commenters make the point that assembler is CPU dependent and that the OS is irrelevant, but it seems pointless to me to pick a book that has assembly examples that refer to MS-DOS interrupts and memory layouts. Likewise, learning assembler on Linux would seem to produce Linux executables Are there any: 1) Modern 2) x86/x64 3) on Windows platform - book resources available ? The reason I am targeting the Win platform is I would like to do low-level, OS internals programming, to supplement my Win C/C++ work. Thanks

• Fonts in a multi-platform environment

  - by Stephen Burke

  What is the best way to deal with fonts in a multi-platform distributed system? If I want to use a common font across all systems to show to the user, what's the best way to do this. From the little I've been reading each platform looks to have fonts that are of the same family (ie serif, sans-serif) but with different names. CSS looks to have the functionality baked in where it will make the best selection it can of font on the users machine. Is there similar functionality either in system libraries or external libraries for Windows & Linux. I'm using C++ mainly? Can someone point me in the right direction for documentation as well? Thanks

• You may be tempted by IaaS, but you should PaaS on that or your database cloud journey will be a short one

  - by B R Clouse

  Before we examine Consolidation, the next step in the journey to cloud, let's take a short detour to address a critical choice you will face at the outset of your journey: whether to deploy your databases in virtual machines or not. A common misconception we've encountered is the belief that moving to cloud computing can be accomplished by simply hosting one's current operating environment as-is within virtual machines, and then stacking those VMs together in a consolidated environment.  This solution is often described as "Infrastructure as a Service" (IaaS) because the building block for deployments is a VM, which behaves like a full complement of infrastructure.  This approach is easy to understand and may feel like a good first step, but it won't take your databases very far in the journey to cloud computing.  In fact, if you follow the IaaS fork in the road, your journey will end quickly, without realizing the full benefits of cloud computing.  The better option to is to rationalize the deployment stack so that VMs are needed only for exceptional cases.  By settling on a standard operating system and patch level, you create an infrastructure that potentially all of your databases can share.  Now, the building block will be database instances or possibly schemas within databases.  These components are the platforms on which you will deploy workloads, hence this is known as "Platform as a Service" (PaaS). PaaS opens the door to higher degrees of consolidation than IaaS, because with PaaS you will not need to accommodate the footprint (operating system, hypervisor, processes, ...) that each VM brings with it.  You will also reduce your maintenance overheard if you move forward without the VMs and their O/Ses to patch and monitor.  So while IaaS simply shuffles complex and varied environments into VMs,  PaaS actually reduces complexity by rationalizing to the small possible set of components.  Now we're ready to look at the consolidation options that PaaS provides -- in our next blog posting.

• need help speeding up tag cloud filter for IE

  - by rod

  Hi All, Any ideas on how to speed this up in IE (performs decent in Firefox, but almost unusable in IE). Basically, it's a tag cloud with a filter text box to filter the cloud. <html> <head> <script type="text/javascript" src="jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(document).ready(function(){ $('#tagFilter').keyup(function(e) { if (e.keyCode==8) { $('#cloudDiv > span').show(); } $('#cloudDiv > span').not('span:contains(' + $(this).val() + ')').hide(); }); }); </script> </head> <body> <input type="text" id="tagFilter" /> <div id="cloudDiv" style="height: 200px; width: 400px; overflow: auto;"> <script type="text/javascript"> for (i=0;i<=1300;i++) { document.write('<span><a href="#">Test ' + i + '</a>&nbsp;</span>'); } </script> </div> </body> </html> thanks, rodchar

• AWS Cloud Formation.Requires capabilities : [CAPABILITY_IAM] (Child Stack)

  - by Drew Khoury

  I'm running a CloudFormation template in the AWS Console. Running Stack Directly I started with a template that used IAM resources, and the console prompts me to acknowledge IAM capabilities when running the stack directly. Running Stack as a child I then tried to call the same stack from a parent stack and did not receive the same prompt. The stack then failed with the message: Requires capabilities : [CAPABILITY_IAM] Research The docs indicate that I can run CF scripts in a number of ways. There's plenty of docs around CLI/API and supplying the capability parameter, but there appears to be no information about how to make sure it's applied when running through the console. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html IAM Resources in AWS CloudFormation Templates CF Console CLI API What I've done / What I think I've raised an issue via the forum for now, but no response (yet): https://forums.aws.amazon.com/thread.jspa?threadID=139160 I suspect this is a bug in the Console, as there doesn't appear to be any documentation of how to change the behaviour via the console and as far as I'm aware this should just work. Anyone came across the same problem, or can report that it's working fine for them?

• Using Cloud Formation provisioned security group with specific subnet

  - by Fred Clausen

  Summary I'm attempting to create an AWS CloudFormation template which contains an instance for which I want to select a particular subnet. If I specify the subnet ID then I get the following error The parameter groupName cannot be used with the parameter subnet. From reading this thread it appears I need to provide security group IDs - not names. How can I create a security group in CloudFormation and then get its ID after the fact? Details The relevant part of the instance config is as follows "WebServerHost": { "Type" : "AWS::EC2::Instance", <..skipping metadata...> "Properties": { "ImageId" : { "ami-1234" }, "InstanceType" : { "Ref" : "WebServerInstanceType" }, "SecurityGroups" : [ {"Ref" : "WebServerSecurityGroup"} ], "SubnetId" : "subnet-abcdef123", and the security group looks as follows "WebServerSecurityGroup" : { "Type" : "AWS::EC2::SecurityGroup", "Properties" : { "GroupDescription" : "Enable HTTP and SSH", "SecurityGroupIngress" : [ {"IpProtocol" : "tcp", "FromPort" : "80", "ToPort" : "80", "CidrIp" : "0.0.0.0/0"}, {"IpProtocol" : "tcp", "FromPort" : "22", "ToPort" : "22", "CidrIp" : "0.0.0.0/0"} ] } }, How can I create and then get that security group's ID?

• What proportion of DBA skills are platform-independent?

  - by Arkaaito

  Problem: we've grown to the point where we need a real DBA. Real DBAs are hard to find. Possible solution: I know someone with extensive experience (currently working on MSSQL) who is looking for a new DBA job. He might be willing to consider working for a MySQL shop (I haven't asked). Snag: I don't know to what extent MSSQL DBA skills map to MySQL DBA skills. I'm a developer, so I know enough about MySQL to develop apps which use it (including the basic performance-tuning, index selection, etc.), do schema design, and perform simple utility tasks (backup with mysqldump, scripting, etc.). I don't know anything about MSSQL. Nor do I actually know much about the boundaries of the DBA role. Can anyone with more experience - perhaps as a DBA - weigh in on this? Are there enough similarities between MSSQL and MySQL that it's worth asking a MSSQL DBA if he'd be interested in applying for a MySQL position?

• Static NAT in AWS's Virtual Private Cloud (VPC)

  - by user1050797

  Currently in a VPC with a public and a private subnet, all internet bound traffic from the private subnet could be routed via an NAT instance. The NAT instance will port address translate the packet's source IP to use the NAT instance's elastic IP, so the public server can reply to this public address. This is a PAT mechanism. My question is there a way for me to do a static NAT on my NAT instance -- Using the same NAT instance to static NAT an unassociated but reserved elastic IP to a private subnet host. This NAT instance will behave like a physical firewall doing static nat'ing for a bunch of private ip's.

• Cross platform support for network attached USB hubs?

  - by larsks

  I am looking at network-attached USB hubs in order to run licensed software in a virtualized environment when hardware dongles are required. Are there any solutions that will work with both Linux and Windows? Most of the dedicated devices -- such as the Zonet ZUH2214 or the (oddly expensive) Digi AnywherUSB/2 -- appear to be Windows-only. Linux has the the USB/IP project, for which there appear to be Windows drivers, but the last "News" post on the site was in 2007, so I'm not entirely confident about the viability of the project. Has anyone out there found a solution that will work well in both environments?

• How to trigger cross-platform jobs between Windows and Unix

  - by andyb

  I have an application which has components on Windows and Unix. I need to run overnight jobs which initiate tasks/jobs on both environment. These need to be sequenced so I cannot simple use Cron / Task Scheduler. For each job, there will be a controlling script either on Windows or Unix, but this script will need to initiate jobs on the other environment and detect when they are complete and a success/failure code. In the past I have achieved this using 'flag files' on a samba share. This worked but required 'polling' behaviour on the receiving end which I do not consider optimal. I would prefer not to have to embed user credentials in script if possible.

• One bigger Virtual Machine in Cloud

  - by flyer

  I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with e.g. 12 cores? ------------------------------- | VM (12c) | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | VM (4c) | VM (4c) | VM (4c) | ------------------------------- | Bare Metal (8c) | ------------------------------- I need this information to have a bigger picture to continue.

• moved wordpress site to rackspace cloud, now custom queries breaks code

  - by nikki

  Moved a wordpress site onto a rackspace account from a linux server. Everything is working except for any custom post queries that I programmed. these were working just fine before, and I have tested to make sure it is these queries that is breaking the code. For example here is a snippet that will make the page not load <?php query_posts( "p=215" ); ?> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <? the_content(); ?> <? endwhile; endif; wp_reset_query(); ?> Does anyone have any insights? My thoughts are that the switch to Rackspace account has something to do with it.

• Thin client - cloud machine - to run via iPad, iPhone, most Androids etc

  - by Carl Lindberg

  I'm tired of having a laptop macbook that breaks down or having files that I need to sync via dropbox etc all the time via the machines to different OS installations. It sucks. I want a thin client where I can login on any machine - my iPhone, PC desktop, iPad etc to one running machine. I would like to replace a modernly powerful desktop iMac with a thin client running via my iPad. I will connect the iPad with a keyboard/mouse too so you get the idea. But I want to be able to use some of the Android phones as well (I guess most Android phones today has a good enough performance/resolution etc to run a thin client). Of course it has to be able to have input/output in sound. Printing can be solved by PDF/emailing etc - so no direct communication to the printer ports to USB etc is necessary. Is there such a service today? It should cost somewhere under something like $40/ month. I will run stuff like CPU heavy duty ableton for music production, xCode for making iOS apps, some games etc. And on the thin client also run virtual machines. VM of Ubuntu and Windows.

• Laptop hardware recommendations for multi-platform development

  - by iama

  I am thinking of buying a laptop with the following configuration - Intel core 2 duo(or I3-330M)/ 4GB RAM/300+ GB 7200 RPM. I would like to be able to run two server VMs on this laptop with Win2K8 and Ubuntu (preferably 64 bit editions). Windows 7 will be the Host OS since that is the one that ships with the laptop. I am thinking of using VMWare player to run the two server OSs. Is this laptop good enough to run the two VMs side by side or do I need to go for a better configuration? Any suggestions? Thanks.

• Cloud based backup solutions based on open standards?

  I am looking for a solution to backup and consolidate important media from a couple Windows laptops and Mac laptop. I would like a solutions that based on open standards, so my data isn't trapped by proprietary formats and proprietary protocols. I would like the ability to switch clients or change providers in the future. For example, something like Jungle Disk plus S3 sounds like a great option. However, I am having trouble confirming how or if this can be setup meeting this criteria. Are there any real or de-facto standards for treating S3 as a filesystem? If so, what Windows and Mac clients support these standards?

• What is good usage scenario for Rackspace Cloud Files CDN (powered by AKAMAI) [closed]

By investigating it thru http://www.just-ping.com/ it seems, that from many places the ping is very high, and during quick investigation I found that they use GeoIP to resolve addresses based on WHOIS, which is not accurate and because of that from many places the ping is above 300ms (for example, if ISP is in balgladore and request is routed to bangladore even if it's 300ms, for period of 1 month), while by just using Amazon Web Services and Route 53 Anycast DNS servers and only 4 EC2 instances it seems that for example India is always below 100ms, while using Akamai it goes above 300ms in some cases, and this is because Route 53 is using BGP. By quickly checking the Akamai, it seems that they are not getting feedback from the traffic - the high ping stays constant even if I keep downloading large files and videos, which is opposite to what they say on their website. They state, that they optimize the performance by taking feedback from the requests, while it seems they just use GeoIP with per City resolution (which are mostly big cities). Because of this, AWS with Route 53 / Anycast DNS seems to be much more reliable, as well EdgeCast which is using BGP, but I dont know how much does it cost to deploy static website. Actually, I dont know if EdgeCast is not a lie, because from isolated places there are many errors - so their performance is at the cost of quality of delivery, because of BGP switching the routes during transfer of large files. So I was wondering, what is really Akamai good for, because they dont seem to pose any strength in any field in what I do understand now, except they offer some software based WAF on their website, but what I really care about is the core distribiution, so the question is? Is really Akamai good for Videos? For static websites? ??? I found so far AWS most usable with most consistent ping and stable transfers.
