• Silverlight ProgressBar issues with Binding

  - by Chris Skardon

  The ProgressBar pretty much does what it says on the tin, displays progress, in a bar form (well, by default anyhow). It’s pretty simple to use: <ProgressBar Minimum="0" Maximum="100" Value="50"/> Gives you a progress bar with 50% of it filled: Easy! But of course, we’re wanting to use binding to change the value, again, pretty easy, have a ViewModel with a ‘Value’ in it, and bind: <ProgressBar Minimum="0" Maximum="100" Value="{Binding Value}"/> Spiffy, and whilst we’re at it, why not bind the Maximum value as well – after all, we can’t be sure of the size of the progress, and it’s a pain to have to work out the percentage (when the progress bar can do it for us): <ProgressBar Minimum="0" Maximum="MaximumValue" Value="{Binding Value}"/> Right, this will work absolutely fine. Or will it??? On the face of it, it looks good, and testing it shows no issues, until at one point we go from: Maximum = 100; Value = 90; to Maximum=60; Value=50; On the face of it not unreasonable. The problem is more obvious if we look at the states of the properties after each set (initially Maximum is set at 1, Value = 0): Code Maximum Value Value < Maximum Maximum = 100; 100 0 True Value = 90; 100 90 True Maximum = 60; 60 90 False Value = 50; 60 50 True Everything is good until the Value is less than the Maximum, at this point the Progress Bar breaks. That’s right, it no longer updates itself, it will always look 100% full. The simple solution – always ensuring you set Value before Maximum is fine unless you’re using a ProgressBar in a less controlled environment – where for example you’re setting a ‘container’ with both values at the same time. The example I have is in a DataTemplate, I have a DataTemplate for a BusyIndicator, (specifically the BusyContentTemplate). The binding works this way: <BusyIndicator BusyContent="{Binding BusyContent}" BusyContentTemplate="{Binding ProgressTemplate}"/> With the template as the ProgressBar defined above… I was setting my BusyContent like this: BusyContent = content; aaaaaand finally, ‘content’ is a class: public class ContentClass : INotifyPropertyChanged { //Obviously this is properly implemented… public double Maximum { get;set;} public double Value { get;set;} } Soooo… As I was replacing the BusyContent wholesale, the order of the binding being set was outside of my control, so – how to go about it? Basically? Fudge it. Modify the ContentClass to include a method: public void Update(double value, double max) { Value = value; Maximum = max; } and change where the setting is to be: BusyContent.Update(content.Value, content.Maximum); Thereby getting the order correct.. Obvious really. Meh :|

• How do I use setFilmSize in panda3d to achieve the correct view?

  - by lhk

  I'm working with Panda3d and recently switched my game to isometric rendering. I moved the virtual camera accordingly and set an orthographic lens. Then I implemented the classes "Map" and "Canvas". A canvas is a dynamically generated mesh: a flat quad. I'm using it to render the ingame graphics. Since the game itself is still set in a 3d coordinate system I'm planning to rely on these canvases to draw sprites. I could have named this class "Tile" but as I'd like to use it for non-tile sketches (enemies, environment) as well I thought canvas would describe it's function better. Map does exactly what it's name suggests. Its constructor receives the number of rows and columns and then creates a standard isometric map. It uses the canvas class for tiles. I'm planning to write a map importer that reads a file to create maps on the fly. Here's the canvas implementation: class Canvas: def __init__(self, texture, vertical=False, width=1,height=1): # create the mesh format=GeomVertexFormat.getV3t2() format = GeomVertexFormat.registerFormat(format) vdata=GeomVertexData("node-vertices", format, Geom.UHStatic) vertex = GeomVertexWriter(vdata, 'vertex') texcoord = GeomVertexWriter(vdata, 'texcoord') # add the vertices for a flat quad vertex.addData3f(1, 0, 0) texcoord.addData2f(1, 0) vertex.addData3f(1, 1, 0) texcoord.addData2f(1, 1) vertex.addData3f(0, 1, 0) texcoord.addData2f(0, 1) vertex.addData3f(0, 0, 0) texcoord.addData2f(0, 0) prim = GeomTriangles(Geom.UHStatic) prim.addVertices(0, 1, 2) prim.addVertices(2, 3, 0) self.geom = Geom(vdata) self.geom.addPrimitive(prim) self.node = GeomNode('node') self.node.addGeom(self.geom) # this is the handle for the canvas self.nodePath=NodePath(self.node) self.nodePath.setSx(width) self.nodePath.setSy(height) if vertical: self.nodePath.setP(90) # the most important part: "Drawing" the image self.texture=loader.loadTexture(""+texture+".png") self.nodePath.setTexture(self.texture) Now the code for the Map class class Map: def __init__(self,rows,columns,size): self.grid=[] for i in range(rows): self.grid.append([]) for j in range(columns): # create a canvas for the tile. For testing the texture is preset tile=Canvas(texture="../assets/textures/flat_concrete",width=size,height=size) x=(i-1)*size y=(j-1)*size # set the tile up for rendering tile.nodePath.reparentTo(render) tile.nodePath.setX(x) tile.nodePath.setY(y) # and store it for later access self.grid[i].append(tile) And finally the usage def loadMap(self): self.map=Map(10, 10, 1) this function is called within the constructor of the World class. The instantiation of world is the entry point to the execution. The code is pretty straightforward and runs good. Sadly the output is not as expected: Please note: The problem is not the white rectangle, it's my player object. The problem is that although the map should have equal width and height it's stretched weirdly. With orthographic rendering I expected the map to be a perfect square. What did I do wrong ? UPDATE: I've changed the viewport. This is how I set up the orthographic camera: lens = OrthographicLens() lens.setFilmSize(40, 20) base.cam.node().setLens(lens) You can change the "aspect" by modifying the parameters of setFilmSize. I don't know exactly how they are related to window size and screen resolution but after testing a little the values above seem to work for me. Now everything is rendered correctly as long as I don't resize the window. Every change of the window's size as well as switching to fullscreen destroys the correct rendering. I know that implementing a listener for resize events is not in the scope of this question. However I wonder why I need to make the Film's height two times bigger than its width. My window is quadratic ! Can you tell me how to find out correct setting for the FilmSize ? UPDATE 2: I can imagine that it's hard to envision the behaviour of the game. At first glance the obvious solution is to pass the window's width and height in pixels to setFilmSize. There are two problems with that approach. The parameters for setFilmSize are ingame units. You'll get a way to big view if you pass the pixel size For some strange reason the image is distorted if you pass equal values for width and height. Here's the output for setFilmSize(800,800) You'll have to stress your eyes but you'll see what I mean

• Windows Azure SDK 1.3 addresses early adopter feedback

  - by Eric Nelson

  At the end of November 2010 we released a new version of the Windows Azure SDK which contains many new features driven by the great feedback of early adopters plus a shiny new portal. New Portal implemented in Silverlight: The new portal is implemented using Silverlight and replaces the (IMHO rather clunky) original HTML + JavaScript portal. It is 100% better although does still have a few bugs. Enjoy! P.S. You can if you wish still use the old portal:   New runtime functionality: The following functionality is now generally available through the Windows Azure SDK and Windows Azure Tools for Visual Studio and the new Windows Azure Management Portal: Elevated Privileges and Full IIS. You can now run a portion or all of your code in Web and Worker roles with elevated administrator privileges. The Web role now provides Full IIS functionality, which enables multiple IIS sites per Web role and the ability to install IIS modules. Remote Desktop functionality enables you to connect to a running instance of your application or service in order to monitor activity and troubleshoot common problems. Windows Server 2008 R2 Roles: Windows Azure now supports Windows Server 2008 R2 in its Web, worker and VM roles. This new support enables you to take advantage of the full range of Windows Server 2008 R2 features such as IIS 7.5, AppLocker, and enhanced command-line and automated management using PowerShell Version 2.0. New runtime functionality – in beta: Windows Azure Virtual Machine Role: Support for more types of new and existing Windows applications will soon be available with the introduction of the Virtual Machine (VM) role. You can move more existing applications to Windows Azure, reducing the need to make costly code or deployment changes. Extra Small Windows Azure Instance, which is priced at $0.05 per compute hour, provides developers with a cost-effective training and development environment. Developers can also use the Extra Small instance to prototype cloud solutions at a lower cost. Windows Azure Connect: (formerly Project Sydney), which enables a simple and easy-to-manage mechanism to set up IP-based network connectivity between on-premises and Windows Azure resources, is the first Windows Azure Virtual Network feature that we’re making available as a CTP. You can sign up for any of the betas via the Windows Azure Management Portal. Improved processes and simplified operations New portal! (see above) Access to new diagnostic information including the ability to click on a role to see role type, deployment time and last reboot time A new sign-up process that dramatically reduces the number of steps needed to sign up for Windows Azure. New scenario based Windows Azure Platform forums to help answer questions and share knowledge more efficiently. Multiple Service Administrators: Windows Azure now supports multiple Windows Live IDs to have administrator privileges on the same Windows Azure account. The objective is to make it easy for a team to work on the same Windows Azure account while using their individual Windows Live IDs.   Related Links Please also let us know through Microsoft Platform Ready if and when you intend to build an application using the Windows Azure Platform. Or indeed if you already have (Well done). You will get access to some great benefits if you do (more on that in a future post). It also really helps us better understand the demand out there which directly impacts how we will plan the next six months of activities around the Windows Azure Platform.

• Converting a PV vm back into an HVM vm

  - by wim.coekaerts

  I have been doing some Oracle VM benchmark stuff in the last week or 2 in my off hours and yesterday I wanted to convert one of my VMs that was based on a paravirt kernel into a vm that just boots as a regular hardware virt VM with a standard x86-64 kernel. It took me a little while to figure out the fastest way so now that I have it pretty much down I wanted to share the steps. A PV kernel uses pygrub and a paravirt kernel image that lives on the vm image virtual disk. since this disk image does not have to be bootable it doesn't contain a boot sector and if you just restart the VM in hvm mode the virtual bios will just not do much as it can't start the boot process from disk The first thing I do is make a backup of my vm.cfg file :-) and then edit it as follows : the original file contains : bootloader = '/usr/bin/pygrub' I replace that with : acpi = 1 apic = 1 builder = 'hvm' device_model = '/usr/lib/xen/bin/qemu-dm' kernel = '/usr/lib/xen/boot/hvmloader' then changing the disk files. I change my xvd disks to hd disks and I copy over the iso image of my instal lDVD. In the case of my VM template it was based on OL5U4 So I downloaded Enterprise-R5-U4-Server-x86_64-dvd.iso and added it as a cd device. disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,xvda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,xvdb,w', ] to disk = ['file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/System.img,hda,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Oracle11202RAC_x86_64-xvdb.img,hdb,w', 'file:/ovs/OVM_EL5U4_X86_64_11202RAC_PVM/Enterprise-R5-U4-Server-x86_64-dvd.iso, hdc:cdrom,r', ] boot='d' for the network devices (vifs) I change : vif = ['bridge=xenbr2,type=netfront'] to vif = ['bridge=xenbr2,type=ioemu'] That should do it. Next, inside the VM, I copy over the regular kernel rpm that I want to end up running in hvm mode. In this example case it was : kernel-2.6.18-164.0.0.0.1.el5.x8664.rpm. I will use that later on in the process. I put this kernel simply in /root At this point I just start the vm with xm create vm.cfg and start my vnc console to the vm console. Oracle Linux will boot from the iso image, I just go through the install steps and click on UPgrade existing (not re-install). Because the VM is the same as the ISO the install won't actually do anything and it will run through instantly. When the "Reboot" button pops up, don't reboot. Switch to the command prompt console. hi alt-f2 to go to the shell prompt. Now it's easy : umount /mnt/sysimage/boot cd /mnt/sysimage chroot . mount /dev/hda1 (if that was your /boot partition) export PATH=/sbin:$PATH (just to clean that up) edit /etc/modprobe.conf and comment out the xen modules (just put a # in front) Install grub. if your /boot is hda1 then that is (hd0,0) $ grub root (hd0,0) setup (hd0) exit grub now you have a good bootsector, grub installed and you have your grub.conf file Install the new kernel cd root (this is your old /root in your pv image) rpm -ivh remove (or comment out) boot='d' in your vm.cfg restart the VM and you should be good to go, regular grub should start and load your environment. Caveats : this assumes you used labels for your filesystems. if /etc/fstab were to have devices listed then you would have to rename these device before rebooting as well. If you had a /dev/xvda disk then this would be /dev/hda or /dev/sda. All in all it is a relatively short and simple process.

• Managing Operational Risk of Financial Services Processes – part 1/ 2

  - by Sanjeevio

  Financial institutions view compliance as a regulatory burden that incurs a high initial capital outlay and recurring costs. By its very nature regulation takes a prescriptive, common-for-all, approach to managing financial and non-financial risk. Needless to say, no longer does mere compliance with regulation will lead to sustainable differentiation.  Genuine competitive advantage will stem from being able to cope with innovation demands of the present economic environment while meeting compliance goals with regulatory mandates in a faster and cost-efficient manner. Let’s first take a look at the key factors that are limiting the pursuit of the above goal. Regulatory requirements are growing, driven in-part by revisions to existing mandates in line with cross-border, pan-geographic, nature of financial value chains today and more so by frequent systemic failures that have destabilized the financial markets and the global economy over the last decade.  In addition to the increase in regulation, financial institutions are faced with pressures of regulatory overlap and regulatory conflict. Regulatory overlap arises primarily from two things: firstly, due to the blurring of boundaries between lines-of-businesses with complex organizational structures and secondly, due to varying requirements of jurisdictional directives across geographic boundaries e.g. a securities firm with operations in US and EU would be subject different requirements of “Know-Your-Customer” (KYC) as per the PATRIOT ACT in US and MiFiD in EU. Another consequence and concomitance of regulatory change is regulatory conflict, which again, arises primarily from two things: firstly, due to diametrically opposite priorities of line-of-business and secondly, due to tension that regulatory requirements create between shareholders interests of tighter due-diligence and customer concerns of privacy. For instance, Customer Due Diligence (CDD) as per KYC requires eliciting detailed information from customers to prevent illegal activities such as money-laundering, terrorist financing or identity theft. While new customers are still more likely to comply with such stringent background checks at time of account opening, existing customers baulk at such practices as a breach of trust and privacy. As mentioned earlier regulatory compliance addresses both financial and non-financial risks. Operational risk is a non-financial risk that stems from business execution and spans people, processes, systems and information. Operational risk arising from financial processes in particular transcends other sources of such risk. Let’s look at the factors underpinning the operational risk of financial processes. The rapid pace of innovation and geographic expansion of financial institutions has resulted in proliferation and ad-hoc evolution of back-office, mid-office and front-office processes. This has had two serious implications on increasing the operational risk of financial processes: ·         Inconsistency of processes across lines-of-business, customer channels and product/service offerings. This makes it harder for the risk function to enforce a standardized risk methodology and in turn breaches harder to detect. ·         The proliferation of processes coupled with increasingly frequent change-cycles has resulted in accidental breaches and increased vulnerability to regulatory inadequacies. In summary, regulatory growth (including overlap and conflict) coupled with process proliferation and inconsistency is driving process compliance complexity In my next post I will address the implications of this process complexity on financial institutions and outline the role of BPM in lowering specific aspects of operational risk of financial processes.

• Does your analytic solution tell you what questions to ask?

  - by Manan Goel

  Analytic solutions exist to answer business questions. Conventional wisdom holds that if you can answer business questions quickly and accurately, you can take better business decisions and therefore achieve better business results and outperform the competition. Most business questions are well understood (read structured) so they are relatively easy to ask and answer. Questions like what were the revenues, cost of goods sold, margins, which regions and products outperformed/underperformed are relatively well understood and as a result most analytics solutions are well equipped to answer such questions. Things get really interesting when you are looking for answers but you don’t know what questions to ask in the first place? That’s like an explorer looking to make new discoveries by exploration. An example of this scenario is the Center of Disease Control (CDC) in United States trying to find the vaccine for the latest strand of the swine flu virus. The researchers at CDC may try hundreds of options before finally discovering the vaccine. The exploration process is inherently messy and complex. The process is fraught with false starts, one question or a hunch leading to another and the final result may look entirely different from what was envisioned in the beginning. Speed and flexibility is the key; speed so the hundreds of possible options can be explored quickly and flexibility because almost everything about the problem, solutions and the process is unknown.  Come to think of it, most organizations operate in an increasingly unknown or uncertain environment. Business Leaders have to take decisions based on a largely unknown view of the future. And since the value proposition of analytic solutions is to help the business leaders take better business decisions, for best results, consider adding information exploration and discovery capabilities to your analytic solution. Such exploratory analysis capabilities will help the business leaders perform even better by empowering them to refine their hunches, ask better questions and take better decisions. That’s your analytic system not only answering the questions but also suggesting what questions to ask in the first place. Today, most leading analytic software vendors offer exploratory analysis products as part of their analytic solutions offerings. So, what characteristics should be top of mind while evaluating the various solutions? The answer is quite simply the same characteristics that are essential for exploration and analysis – speed & flexibility. Speed is required because the system inherently has to be agile to handle hundreds of different scenarios with large volumes of data across large user populations. Exploration happens at the speed of thought so make sure that you system is capable of operating at speed of thought. Flexibility is required because the exploration process from start to finish is full of unknowns; unknown questions, answers and hunches. So, make sure that the system is capable of managing and exploring all relevant data – structured or unstructured like databases, enterprise applications, tweets, social media updates, documents, texts, emails etc. and provides flexible Google like user interface to quickly explore all relevant data. Getting Started You can help business leaders become “Decision Masters” by augmenting your analytic solution with information discovery capabilities. For best results make sure that the solution you choose is enterprise class and allows advanced, yet intuitive, exploration and analysis of complex and varied data including structured, semi-structured and unstructured data.  You can learn more about Oracle’s exploratory analysis solutions by clicking here.

• Why I Love the Social Management Platform I Use

  - by Mike Stiles

  Not long ago, I asked the product heads for the various components of the Oracle Social Cloud’s SRM to say what they thought was coolest about their component. And while they did a fine job, it was recently pointed out to me that no one around here uses the platform in a real-world setting more than I do, as I not only blog and podcast my brains out, I also run Oracle Social’s own social properties. Of course I’m pro-Oracle Social’s product. Duh. But if you can get around immediately writing this off as a puff piece, there are real reasons beyond my employment that the Oracle SRM works for me as a community manager. If it didn’t, I could have simply written about something else, like how people love smartphones or something genius like that. Post Grid I like seeing what I want to see. I’m difficult that way. Post grid lets me see all posts for all channels, with custom columns showing me how posts are doing. I can filter the grid by social channel, published, scheduled, draft, suggested, etc. Then there’s a pullout side panel that shows me post details, including engagement analytics. From the pullout, I can preview the post, do a quick edit, a full edit, or (my favorite) copy a post so I can edit it and schedule it for other times so I don’t have to repeat from scratch. I’m not lazy, just time conscious. The Post Creation Environment Given our post volume, I need this to be as easy as it can be. I can highlight which streams I want the post to go out on, edit for the individual streams, maintain a media library that’s easy to upload to and attach from, tag posts, insert links that auto-shorten to an orac.le shortlink, schedule with a nice calendar visual, geo-target, drop photos inline into Twitter, and review each post. Watching My Channels The Engage component of the Oracle SRM brings in and drops into a grid the activity that’s happening on all my channels. I keep this open round-the-clock. Again, I get to see only what I want; social network, stream, unread messages, engagement by how I labeled them, and date range. I can bring up a post with a click, reply, label it, retweet it, assign it, delete it, archive it, etc. So don’t bother trying to be a troll on my channels. Analytics Social publishing and engaging 24/7 would be pretty unrewarding if I couldn’t see how our audience was responding. Frankly, I get more analytics than I know what to do with (I’m a content creator, not a data analyst). But I do know what numbers I care about, and they’re available by channel, date range, and campaigns. I’m seeing fan count, sources and demographics. I’m seeing engagement, what kinds of posts are getting engagement, and top engagers. I’m seeing my reach, both organic and paid. I’m seeing how individual posts performed in terms of engagement and virality, and posting time/date insight. Have I covered all the value propositions? I’ve covered pathetically few of them. It would be impossible in blog length to give shout-outs to the vast number of features and functionalities. From organizing teams and managing permissions with Workflow to the powerful ability to monitor topics (and your competition) across the web in Listen, it’s a major, and increasingly necessary, weapon in your social marketing arsenal. The life of a Community Manager is not for everybody. So if the Oracle SRM can actually make a Community Manager’s life easier, what’s not to love? I invite you to take a look at and participate in our Oracle Social Cloud social channels!

• Windows Azure Recipe: Consumer Portal

  - by Clint Edmonson

  Nearly every company on the internet has a web presence. Many are merely using theirs for informational purposes. More sophisticated portals allow customers to register their contact information and provide some level of interaction or customer support. But as our understanding of how consumers use the web increases, the more progressive companies are taking advantage of social web and rich media delivery to connect at a deeper level with the consumers of their goods and services. Drivers Cost reduction Scalability Global distribution Time to market Solution Here’s a sketch of how a Windows Azure Consumer Portal might be built out: Ingredients Web Role – this will host the core of the solution. Each web role is a virtual machine hosting an application written in ASP.NET (or optionally php, or node.js). The number of web roles can be scaled up or down as needed to handle peak and non-peak traffic loads. Database – every modern web application needs to store data. SQL Azure databases look and act exactly like their on-premise siblings but are fault tolerant and have data redundancy built in. Access Control (optional) – if identity needs to be tracked within the solution, the access control service combined with the Windows Identity Foundation framework provides out-of-the-box support for several social media platforms including Windows LiveID, Google, Yahoo!, Facebook. It also has a provider model to allow integration with other platforms as well. Caching (optional) – for sites with high traffic with lots of read-only data and lists, the distributed in-memory caching service can be used to cache and serve up static data at higher scale and speed than direct database requests. It can also be used to manage user session state. Blob Storage (optional) – for sites that serve up unstructured data such as documents, video, audio, device drivers, and more. The data is highly available and stored redundantly across data centers. Each entry in blob storage is provided with it’s own unique URL for direct access by the browser. Content Delivery Network (CDN) (optional) – for sites that service users around the globe, the CDN is an extension to blob storage that, when enabled, will automatically cache frequently accessed blobs and static site content at edge data centers around the world. The data can be delivered statically or streamed in the case of rich media content. Training Labs These links point to online Windows Azure training labs where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together. It gives developers the choice to build web applications; applications running on connected devices, PCs, or servers; or hybrid solutions offering the best of both worlds. New or enhanced applications can be built using existing skills with the Visual Studio development environment and the .NET Framework. With its standards-based and interoperable approach, the services platform supports multiple internet protocols, including HTTP, REST, SOAP, and plain XML SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. Windows Azure Services (9 labs) As applications collaborate across organizational boundaries, ensuring secure transactions across disparate security domains is crucial but difficult to implement. Windows Azure Services provides hosted authentication and access control using powerful, secure, standards-based infrastructure. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

• How to recover after embarrassing yourself and your company?

  - by gaearon

  I work in an outsourcing company in Russia, and one of our clients is a financial company located in USA. For the last six months I have been working on several projects for this particular company, and as I was being assigned a larger project, I was invited to work onsite in USA in order to understand and learn the new system. Things didn't work out as well as I hoped because the environment was messy after original developers, and I had to spent quite some time to understand the quirks. However we managed to do the release several days ago, and it looks like everything's going pretty smooth. From technical perspective, my client seems to be happy with me. My solutions seem to work, and I always try to add some spark of creativity to what I do. However I'm very disorganized in a certain sense, as I believe many of you fellas are. Let me note that my current job is my first job ever, and I was lucky enough to get a job with flexible schedule, meaning I can come in and out of the office whenever I want as long as I have 40 hours a week filled. Sometimes I want to hang out with friends in the evening, and days after that I like to have a good sleep in the morning—this is why flexible schedule (or lack of one) is ideal fit for me. [I just realized this paragraph looks too serious, I should've decorated it with some UNICORNS!] Of course, after coming to the USA, things changed. This is not some software company with special treatment for the nerdy ones. Here you have to get up at 7:30 AM to get to the office by 9 AM and then sit through till 5 PM. Personally, I hate waking up in the morning, not to say my productivity begins to climb no sooner than at 5 o'clock, i.e. I'm very slow until I have to go, which is ironic. Sometimes I even stay for more than 8 hours just to finish my current stuff without interruptions. Anyway, I could deal with that. After all, they are paying for my trip, who am I to complain? They need me to be in their working hours to be able to discuss stuff. It makes perfect sense that fixed schedule doesn't make any sense for me. But it does makes sense that it does make sense for my client. And I am here for client, therefore sense is transferred. Awww, you got it. I was asked several times to come exactly at 9 AM but out of laziness and arrogance I didn't take these requests seriously enough. This paid off in the end—on my last day I woke up 10 minutes before final status meeting with business owner, having overslept previous day as well. Of course this made several people mad, including my client, as I ignored his direct request to come in time for two days in the row, including my final day. Of course, I didn't do it deliberately but certainly I could've ensured that I have at least two alarms to wake me up, et cetera...I didn't do that. He also emailed my boss, calling my behavior ridiculous and embarrassing for my company and saying “he's not happy with my professionalism at all”. My boss told me that “the system must work both in and out” and suggested me to stay till late night this day working in a berserker mode, fixing as many issues as possible, and sending a status email to my client. So I did, but I didn't receive the response yet. These are my questions to the great programmers community: Did you have situations where your ignorance and personal non-technical faults created problems for your company? Were you able to make up for your fault and stay in a good relationship with your client or boss? How? How would you act if you were in my situation?

• SQL Authority News – FalafelCON 2014: 2 days with the Best Developers in the World

  - by Pinal Dave

  I love presenting at various forums on various technologies. I am extremely excited that I got invited to speak at Falafel Conference 2014 in San Francisco. I will present two technology sessions on SQL Server. If you are into web development or if you just want to attend a conference with the best of the industry speakers, this may be the right conference for you. What set apart this conference from other conference is technology presented as well as speakers. Usually one has to attend very expensive and high scale event when they have to hear good speakers. At this conference, you will find quite a many industry legends are available to present on the bleeding edge technology. Here are few of the reasons why I believe you should attend this conference: Choose from four tracks covering Web, Mobile development and testing, Sitefinity, and Automated Testing, or attend sessions from all four! Learn from the best developers and testers in the business in an intimate setting. Surround yourself with your peers and the opportunity to network Learn about the latest platforms and technologies including Kendo UI, AngularJS, ASP.NET MVC, WebAPI, and more! Here are the details for the sessions which I am going to present at Falafel Conference. Secrets of SQL Server: Database Worst Practices Abstract: Chances are you have heard, or even uttered, this expression. This demo-oriented session will show many examples where database professionals were dumbfounded by their own mistakes, and could even bring back memories of your own early DBA days. The goal of this session is to expose the small details that can be dangerous to the production environment and SQL Server as a whole, as well as talk about worst practices and how to avoid them. Shedding light on some of these perils and the tricks to avoid them may even save your current job. After attending this session, Developers will only need 60 seconds to improve performance of their database server in their SharePoint implementation. We will have a quiz during the session to keep the conversation alive. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. Additionally, all attendees of the session will have access to learning material presented in the session. The Unsung Hero Abstract: Slow Running Queries are the most common problem that developers face while working with SQL Server. While it is easy to blame the SQL Server for unsatisfactory performance, however the issue often persists with the way queries have been written, and how Indexes has been set up. The session will focus on the ways of identifying problems that slow down SQL Server, and Indexing tricks to fix them. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. Register Now! I have learned from the Falafel Team that they are running out of tickets and soon they will close the registration.  For next 10 days the price for the registration is only USD 149. Trust me, you can’t get such a world class training and networking opportunity at such a low price. Click to Register Here!

• EPM troubleshooting Utilities

  - by THE

  (in via Maurice) "Are you keeping up-to-date with the latest troubleshooting utilities introduced from EPM 11.1.2.2? These are typically not described in product documentation, so you might miss references to them. The following five utilities may be run from the command line.(1) Deployment Report was introduced with EPM 11.1.2.2 (11 April 2012). It details logical web addresses, web servers, application ports, database connections, user directories, database repositories configured for the EPM system, data directories used by EPM system products, instance directories, FMW homes, deployment distory, et cetera. It also helps to keep you honest about whether you made changes to the system and at what times! Download Shared Services patch 13530721 to get the backported functionality in EPM 11.1.2.1. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/epmsys_registry.sh report deployment (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\epmsys_registry.bat report deployment (on Microsoft Windows). The output is saved under \Oracle\Middleware\user_projects\epmsystem1\diagnostics\reports\deployment_report.html (2) Log Analysis has received more "press". It was released with EPM 11.1.2.3 and helps the user to slice and dice EPM logs. It has many parameters which are documented when run without parameters, when run with the -h parameter, or in the 'Readme' file. It has also been released as a standalone utility for EPM 11.1.2.3 and earlier versions. (Sign in to  My Oracle Support, click the 'Patches & Updates' tab, enter the patch number 17425397, and click the Search button. Download the appropriate platform-specific zip file, unzip, and read the 'Readme' file. Note that you must provide a proper value to a JAVA_HOME environment variable [pointer to the mother directory of the Java /bin subdirectory] in the loganalysis.bat | .sh file and use the -d parameter when running standalone.) Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/loganalysis.sh -h (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\loganalysis.bat -h (on Microsoft Windows). The output is saved under the \Oracle\Middleware\user_projects\epmsystem1\diagnostics\reports\ subdirectory. (3) The Registry Cleanup command may be used (without fear!) to clean up various corruptions which can  affect the Hyperion (database-based) Repository. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/registry-cleanup.sh (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\registry-cleanup.bat (on Microsoft Windows). The actions are described on the command line. (4) The Remove Instance Command is only used if there are two or more instances configured on one computer and one of those should be deleted. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/remove-instance.sh (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\remove-instance.bat (on Microsoft Windows). (5) The Reset Configuration Tool was introduced with EPM 11.1.2.2. It nullifies Shared Services Hyperion Registry settings so that a service may be reconfigured. You may locate the values to substitute for <product> or <task> by scanning registry.html (generated by running epmsys_registry.bat | .sh). Find productNAME in INSTANCE_TASKS_CONFIGURATION and SYSTEM_TASKS_CONFIGURATION nodes and identify tasks by property pairs that have values of 'Configurated' or 'Pending'. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/resetConfigTask.sh -product <product> -task <task> (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\resetConfigTask.bat -product <product> -task <task> (on Microsoft Windows). "Thanks to Maurice for this collection of utilities.

• WebLogic Server Performance and Tuning: Part II - Thread Management

  - by Gokhan Gungor

  WebLogic Server, like any other java application server, provides resources so that your applications use them to provide services. Unfortunately none of these resources are unlimited and they must be managed carefully. One of these resources is threads which are pooled to provide better throughput and performance along with the fast response time and to avoid deadlocks. Threads are execution points that WebLogic Server delivers its power and execute work. Managing threads is very important because it may affect the overall performance of the entire system. In previous releases of WebLogic Server 9.0 we had multiple execute queues and user defined thread pools. There were different queues for different type of work which had fixed number of execute threads.  Tuning of this thread pools and finding the proper number of threads was time consuming which required many trials. WebLogic Server 9.0 and the following releases use a single thread pool and a single priority-based execute queue. All type of work is executed in this single thread pool. Its size (thread count) is automatically decreased or increased (self-tuned). The new “self-tuning” system simplifies getting the proper number of threads and utilizing them.Work manager allows your applications to run concurrently in multiple threads. Work manager is a mechanism that allows you to manage and utilize threads and create rules/guidelines to follow when assigning requests to threads. We can set a scheduling guideline or priority a request with a work manager and then associate this work manager with one or more applications. At run-time, WebLogic Server uses these guidelines to assign pending work/requests to execution threads. The position of a request in the execute queue is determined by its priority. There is a default work manager that is provided. The default work manager should be sufficient for most applications. However there can be cases you want to change this default configuration. Your application(s) may be providing services that need mixture of fast response time and long running processes like batch updates. However wrong configuration of work managers can lead a performance penalty while expecting improvement.We can define/configure work managers at;•    Domain Level: config.xml•    Application Level: weblogic-application.xml •    Component Level: weblogic-ejb-jar.xml or weblogic.xml(For a specific web application use weblogic.xml)We can use the following predefined rules/constraints to manage the work;•    Fair Share Request Class: Specifies the average thread-use time required to process requests. The default is 50.•    Response Time Request Class: Specifies a response time goal in milliseconds.•    Context Request Class: Assigns request classes to requests based on context information.•    Min Threads Constraint: Limits the number of concurrent threads executing requests.•    Max Threads Constraint: Guarantees the number of threads the server will allocate to requests.•    Capacity Constraint: Causes the server to reject requests only when it has reached its capacity. Let’s create a work manager for our application for a long running work.Go to WebLogic console and select Environment | Work Managers from the domain structure tree. Click New button and select Work manager and click next. Enter the name for the work manager and click next. Then select the managed server instances(s) or clusters from available targets (the one that your long running application is deployed) and finish. Click on MyWorkManager, and open the Configuration tab and check Ignore Stuck Threads and save. This will prevent WebLogic to tread long running processes (that is taking more than a specified time) as stuck and enable to finish the process.

• Stepping outside Visual Studio IDE [Part 2 of 2] with Mono 2.6.4

  - by mbcrump

  Continuing part 2 of my Stepping outside the Visual Studio IDE, is the open-source Mono Project. Mono is a software platform designed to allow developers to easily create cross platform applications. Sponsored by Novell (http://www.novell.com/), Mono is an open source implementation of Microsoft's .NET Framework based on the ECMA standards for C# and the Common Language Runtime. A growing family of solutions and an active and enthusiastic contributing community is helping position Mono to become the leading choice for development of Linux applications. So, to clarify. You can use Mono to develop .NET applications that will run on Linux, Windows or Mac. It’s basically a IDE that has roots in Linux. Let’s first look at the compatibility: Compatibility If you already have an application written in .Net, you can scan your application with the Mono Migration Analyzer (MoMA) to determine if your application uses anything not supported by Mono. The current release version of Mono is 2.6. (Released December 2009) The easiest way to describe what Mono currently supports is: Everything in .NET 3.5 except WPF and WF, limited WCF. Here is a slightly more detailed view, by .NET framework version: Implemented C# 3.0 System.Core LINQ ASP.Net 3.5 ASP.Net MVC C# 2.0 (generics) Core Libraries 2.0: mscorlib, System, System.Xml ASP.Net 2.0 - except WebParts ADO.Net 2.0 Winforms/System.Drawing 2.0 - does not support right-to-left C# 1.0 Core Libraries 1.1: mscorlib, System, System.Xml ASP.Net 1.1 ADO.Net 1.1 Winforms/System.Drawing 1.1 Partially Implemented LINQ to SQL - Mostly done, but a few features missing WCF - silverlight 2.0 subset completed Not Implemented WPF - no plans to implement WF - Will implement WF 4 instead on future versions of Mono. System.Management - does not map to Linux System.EnterpriseServices - deprecated Links to documentation. The Official Mono FAQ’s Links to binaries. Mono IDE Latest Version is 2.6.4 That's it, nothing more is required except to compile and run .net code in Linux. Installation After landing on the mono project home page, you can select which platform you want to download. I typically pick the Virtual PC image since I spend all of my day using Windows 7. Go ahead and pick whatever version is best for you. The Virtual PC image comes with Suse Linux. Once the image is launch, you will see the following: I’m not going to go through each option but its best to start with “Start Here” icon. It will provide you with information on new projects or existing VS projects. After you get Mono installed, it's probably a good idea to run a quick Hello World program to make sure everything is setup properly. This allows you to know that your Mono is working before you try writing or running a more complex application. To write a "Hello World" program follow these steps: Start Mono Development Environment. Create a new Project: File->New->Solution Select "Console Project" in the category list. Enter a project name into the Project name field, for example, "HW Project". Click "Forward" Click “Packaging” then OK. You should have a screen very simular to a VS Console App. Click the "Run" button in the toolbar (Ctrl-F5). Look in the Application Output and you should have the “Hello World!” Your screen should look like the screen below. That should do it for a simple console app in mono. To test out an ASP.NET application, simply copy your code to a new directory in /srv/www/htdocs, then visit the following URL: http://localhost/directoryname/page.aspx where directoryname is the directory where you deployed your application and page.aspx is the initial page for your software. Databases You can continue to use SQL server database or use MySQL, Postgress, Sybase, Oracle, IBM’s DB2 or SQLite db. Conclusion I hope this brief look at the Mono IDE helps someone get acquainted with development outside of VS. As always, I welcome any suggestions or comments.

• What is the difference between Workcenters, Dashboards, and the Interaction Hub?

  - by Matthew Haavisto

  Oracle Open World has just concluded.  Over the course of the conference, we presented several sessions covering different aspects of the PeopleSoft user experience, including Workcenters, Dashboards, and the PeopleSoft Interaction Hub (formerly known as the PeopleSoft Applications Portal).  Although we've produced collateral on these features and covered them in sessions, it became apparent at the conference that customers still have many questions about the these products, including how they are licensed, how they are installed, what their various purposes are, and how they can be used together synergistically. Let's Start with Licensing and Installation As you may know, we've extended the restricted use license (RUL) for the Interaction Hub.  This grants customers with PeopleTools 8.52 licenses the right to install the Interaction Hub for free for use as specified in the Tools license notes.  Note that this means customers receive a restricted use license for the Interaction Hub that doesn't cost them an additional license fee, but it is a separate product, not part of PeopleTools or PeopleSoft applications, and is a separate installation.  This means customers must provide the infrastructure to install and run the Hub, just like any other application.  The benefits of using the Hub to unify your PeopleSoft user experience can be great.  PeopleSoft applications have not yet delivered instances of the Hub with their products, though they may in the future. Workcenters and Dashboards, on the other hand, are frameworks provided by PeopleTools.  No other license is required, and no additional installation of a separate product is needed (apart from PeopleTools and PeopleSoft applications).  PeopleSoft applications are delivering instances of the workcenters and dashboards with their products.  Some are available now, and more are coming in future releases.  These delivered workcenter and dashboard instances require no additional licenses, and no additional installations beyond Tools and the applications that provide them.  In addition, the workcenter and dashboard frameworks provided by PeopleTools can be used by customers to build their own workcenters and dashboards, and it's quite easy and simple to do so. What are Their Differences?  What Purposes do they Serve? Workcenters, Dashboards and the Interaction Hub appear somewhat similar.  They all contain pagelets, and have some visual characteristics in common.  However, their strengths and purposes are very different, and they were designed to provide different benefits to your PeopleSoft ecosystem. Workcenters and Dashboards have the following characteristics: Designed for specific roles Focus on the daily tasks of those roles Help to streamline the work performed most often Personal view of my work world Makes navigation and search easier and quicker, particularly for transactions and decision support Reports and data needed for day-to-day work Personalizable, but minimal Delivered by PS Apps, but can be altered by customer for their requirements Customers can create their own Workcenters can be used for guided processes  The Interaction Hub is designed to aggregate content from multiple applications, and is is used to unify the user experience of those applications.  It offers a rich, web site-based user experience, and is often used to provide access to infrequently performed activities like benefits enrollment, payroll inquiries, life event changes, onboarding, and so on. Full-featured and robust Centrally administered Pushed to large audience Broad info like Company News Infrequent activities like benefits, not day-to-day tasks Self-service, access to employer info Central launch point for other activities and can navigate to workcenters and dashboards Deployed by customers or consultants, instances not delivered by PeopleSoft (at this time) Content management Unified PS application navigation Although these products are quite different and serve different purposes in your PeopleSoft environment, they can be used together to provide a richer, more efficient and engaging user experience for your all your user communities.

• Exadata X3, 11.2.3.2 and Oracle Platinum Services

  - by Rene Kundersma

  Oracle recently announced an Exadata Hardware Update. The overall architecture will remain the same, however some interesting hardware refreshes are done especially for the storage server (X3-2L). Each cell will now have 1600GB of flash, this means an X3-2 full rack will have 20.3 TB of total flash ! For all the details I would like to refer to the Oracle Exadata product page: www.oracle.com/exadata Together with the announcement of the X3 generation. A new Exadata release, 11.2.3.2 is made available. New Exadata systems will be shipped with this release and existing installations can be updated to that release. As always there is a storage cell patch and a patch for the compute node, which again needs to be applied using YUM. Instructions and requirements for patching existing Exadata compute nodes to 11.2.3.2 using YUM can be found in the patch README. Depending on the release you have installed on your compute nodes the README will direct you to a particular section in MOS note 1473002.1. MOS 1473002.1 should only be followed with the instructions from the 11.2.3.2 patch README. Like with 11.2.3.1.0 and 11.2.3.1.1 instructions are added to prepare your systems to use YUM for the first time in case you are still on release 11.2.2.4.2 and earlier. You will also find these One Time Setup instructions in MOS note 1473002.1 By default compute nodes that will be updated to 11.2.3.2.0 will have the UEK kernel. Before 11.2.3.2.0 the 'compatible kernel' was used for the compute nodes. For 11.2.3.2.0 customer will have the choice to replace the UEK kernel with the Exadata standard 'compatible kernel' which is also in the ULN 11.2.3.2 channel. Recommended is to use the kernel that is installed by default. One of the other great new things 11.2.3.2 brings is Writeback Flashcache (wbfc). By default wbfc is disabled after the upgrade to 11.2.3.2. Enable wbfc after patching on the storage servers of your test environment and see the improvements this brings for your applications. Writeback FlashCache can be enabled  by dropping the existing FlashCache, stopping the cellsrv process and changing the FlashCacheMode attribute of the cell. Of course stopping cellsrv can only be done in a controlled manner. Steps: drop flashcache alter cell shutdown services cellsrv again, cellsrv can only be stopped in a controlled manner alter cell flashCacheMode = WriteBack alter cell startup services cellsrv create flashcache all Going back to WriteThrough FlashCache is also possible, but only after flushing the FlashCache: alter cell flashcache all flush Last item I like to highlight in particular is already from a while ago, but a great thing to emphasis: Oracle Platinum Services. On top of the remote fault monitoring with faster response times Oracle has included update and patch deployment services.These services are delivered by Oracle Advanced Customer Support at no additional costs for qualified Oracle Premier Support customers.

• SQL SERVER – How to Get SQL Server Restart Notification?

  - by Pinal Dave

  Few days back my friend called me to know if there is any tool which can be used to get restart notification about SQL in their environment. I told that SQL Server can do it by itself with some configurations. He was happy and surprised to know that he need not spend any extra money. In SQL Server, we can configure stored procedure(s) to run at start-up of SQL Server. This blog would give steps to achieve how to achieve it. There are many situations where this feature can be used. Below are few. Logging SQL Server startup timings Modify data in some table during startup (i.e. table in tempdb) Sending notification about SQL start. Step 1 – Enable ‘scan for startup procs’ This can be done either using T-SQL or User Interface of Management Studio. EXEC sys.sp_configure N'Show Advanced Options', N'1' GO RECONFIGURE WITH OVERRIDE GO EXEC sys.sp_configure N'scan for startup procs', N'1' GO RECONFIGURE WITH OVERRIDE GO Below is the interface to change the setting. We need to go to “Server” > “Properties” and use “Advanced” tab. “Scan for Startup Procs” is the parameter under “Miscellaneous” section as shown below. We need to make value as “True” and hit OK. Step 2 – Create stored procedure It’s important to note that the procedure is executed after recovery is finished for ALL databases. Here is a sample stored procedure. You can use your own logic in the procedure. CREATE PROCEDURE SQLStartupProc AS BEGIN CREATE TABLE ##ThisTableShouldAlwaysExists (AnyColumn INT) END Step 3 – Set Procedure to run at startup We need to use sp_procoption to mark the procedure to run at startup. Here is the code to let SQL know that this is startup proc. sp_procoption 'SQLStartupProc', 'startup', 'true' This can be used only for procedures in master database. Msg 15398, Level 11, State 1, Procedure sp_procoption, Line 89 Only objects in the master database owned by dbo can have the startup setting changed. We also need to remember that such procedure should not have any input/output parameter. Here is the error which would be raised. Msg 15399, Level 11, State 1, Procedure sp_procoption, Line 107 Could not change startup option because this option is restricted to objects that have no parameters. Verification Here is the query to find which procedures is marked as startup procedures. SELECT name FROM sys.objects WHERE OBJECTPROPERTY(OBJECT_ID, 'ExecIsStartup') = 1 Once this is done, I have restarted SQL instance and here is what we would see in SQL ERRORLOG Launched startup procedure 'SQLStartupProc'. This confirms that stored procedure is executed. You can also notice that this is done after all databases are recovered. Recovery is complete. This is an informational message only. No user action is required. After few days my friend again called me and asked – I want to turn this OFF? Use comments section and post the answer for him.  Reference: Pinal Dave (http://blog.sqlauthority.com)Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQL Utility, T SQL

• what differs a computer scientist/software engineer to regular people who learn programming language and APIs?

  - by Amumu

  In University, we learn and reinvent the wheel a lot to truly learn the programming concepts. For example, we may learn assembly language to understand, what happens inside the box, and how the system operates, when we execute our code. This helps understanding higher level concepts deeper. For example, memory management like in C is just an abstraction of manually managed memory contents and addresses. The problem is, when we're going to work, usually productivity is required more. I could program my own containers, or string class, or date/time (using POSIX with C system call) to do the job, but then, it would take much longer time to use existing STL or Boost library, which abstract all of those thing and very easy to use. This leads to an issue, that a regular person doesn't need to get through all the low level/under the hood stuffs, who learns only one programming language and using language-related APIs. These people may eventually compete with the mainstream graduates from computer science or software engineer and call themselves programmers. At first, I don't think it's valid to call them programmers. I used to think, a real programmer needs to understand the computer deeply (but not at the electronic level). But then I changed my mind. After all, they get the job done and satisfy all the test criteria (logic, performance, security...), and in business environment, who cares if you're an expert and understand how computer works or not. You may get behind the "amateurs" if you spend to much time learning about how things work inside. It is totally valid for those people to call themselves programmers. This makes me confuse. So, after all, programming should be considered an universal skill? Does programming language and concepts matter or the problems we solve matter? For example, many C/C++ vs Java and other high level language, one of the main reason is because C/C++ features performance, as well as accessing low level facility. One of the main reason (in my opinion), is coding in C/C++ seems complex, so people feel good about it (not trolling anyone, just my observation, and my experience as well. Try to google "C hacker syndrome"). While Java on the other hand, made for simplifying programming tasks to help developers concentrate on solving their problems. Based on Java rationale, if the programing language keeps evolve, one day everyone can map their logic directly with natural language. Everyone can program. On that day, maybe real programmers are mathematicians, who could perform most complex logic (including business logic and academic logic) without worrying about installing/configuring compiler, IDEs? What's our job as a computer scientist/software engineer? To solve computer specific problems or to solve problems in general? For example, take a look at this exame: http://cm.baylor.edu/ICPCWiki/attach/Problem%20Resources/2010WorldFinalProblemSet.pdf . The example requires only basic knowledge about the programming language, but focus more on problem solving with the language. In sum, what differs a computer scientist/software engineer to regular people who learn programming language and APIs? A mathematician can be considered a programmer, if he is good enough to use programming language to implement his formula. Can we programmer do this? Probably not for most of us, since we specialize about computer, not math. An electronic engineer, who learns how to use C to program for his devices, can be considered a programmer. If the programming languages keep being simplified, may one day the software engineers, who implements business logic and create softwares, be obsolete? (Not for computer scientist though, since many of the CS topics are scientific, and science won't change, but technology will).

• Why don't we just fix Javascript?

  - by Jan Meyer

  Javascript sucks because of a few fatalities well pointed out by Douglas Crockford. We talk a lot about it. But the point here is, why we don't fix it? Coffeescript of course does that and a lot more. But the question here is another: if we provide a webservice that can convert one version of Javascript to the next, and so on, we can keep the language up to date. Such a conversion allows old code to run, albeit with an ever-increasing startup delay, as newer browsers convert old code to the new syntax. To avoid that delay, the site only needs to take the output of the code-transform and paste it in! The effort has immediate benefits for those businesses interested in the results. The rest can sleep tight: their code will continue to run. If we provide backward code-transformation also, then elder browsers can also run ANY new code! Migration scripts should be created by those that make changes to a language. Today they don't, which is in itself a fundamental omission! It should be am obvious part of their job to provide them, as their job isn't really done without them. The onus of making it work should be on them. With this system Any site will be able to run in Any browser, but new code will run best on the newest browsers. This way we reap the benefit of an up-to-date and productive development environment, where today we suffer, supposedly because of yesterday. This is a misconception. We are all trapped in committee-thinking, and we drag along things that only worsen our performance over time! We cause an ever increasing complexity that is hard to underestimate. Javascript is easily fixed. The fact is we don't. As an example, I have seen Patrick Michaud tackle the migration problem in PmWiki. It included forward migration scripts. Whenever syntax changes were made, a migration script was added to transform pages to the new syntax. As far as I know, ALL migrations have worked flawlessly. In other words, we don't tackle the migration problem, we just drag it along. We are incompetent! And why is that? Because technically incompetent people feel they must decide for us. Because they are incompetent, fear rules them. They are obnoxiously conservative, and we suffer the consequence of bad leadership. But the competent don't need to play by the same rules. They can (and must) change them. They are the path forward. It is about time to leave the past behind, and pursue the leanest meanest, no, eternal functionality. That would in and of itself revolutionize programming. So, why don't we stop whining and fix programming? Begin with Javascript and change the world. Even if the browser doesn't hook into this system, coders could. So language updaters should take it upon them to provide migration scripts. Once they exist, browsers may take advantage of them.

• Need WIF Training?

  - by Your DisplayName here!

  I spend numerous hours every month answering questions about WIF and identity in general. This made me realize that this is still quite a complicated topic once you go beyond the standard fedutil stuff. My good friend Brock and I put together a two day training course about WIF that covers everything we think is important. The course includes extensive lab material where you take standard application and apply all kinds of claims and federation techniques and technologies like WS-Federation, WS-Trust, session management, delegation, home realm discovery, multiple identity providers, Access Control Service, REST, SWT and OAuth. The lab also includes the latest version of the thinktecture identityserver and you will learn how to use and customize it. If you are looking for an open enrollment style of training, have a look here. Or contact me directly! The course outline looks as follows: Day 1 Intro to Claims-based Identity & the Windows Identity Foundation WIF introduces important concepts like conversion of security tokens and credentials to claims, claims transformation and claims-based authorization. In this module you will learn the basics of the WIF programming model and how WIF integrates into existing .NET code. Externalizing Authentication for Web Applications WIF includes support for the WS-Federation protocol. This protocol allows separating business and authentication logic into separate (distributed) applications. The authentication part is called identity provider or in more general terms - a security token service. This module looks at this scenario both from an application and identity provider point of view and walks you through the necessary concepts to centralize application login logic both using a standard product like Active Directory Federation Services as well as a custom token service using WIF’s API support. Externalizing Authentication for SOAP Services One big benefit of WIF is that it unifies the security programming model for ASP.NET and WCF. In the spirit of the preceding modules, we will have a look at how WIF integrates into the (SOAP) web service world. You will learn how to separate authentication into a separate service using the WS-Trust protocol and how WIF can simplify the WCF security model and extensibility API. Day 2 Advanced Topics:  Security Token Service Architecture, Delegation and Federation The preceding modules covered the 80/20 cases of WIF in combination with ASP.NET and WCF. In many scenarios this is just the tip of the iceberg. Especially when two business partners decide to federate, you usually have to deal with multiple token services and their implications in application design. Identity delegation is a feature that allows transporting the client identity over a chain of service invocations to make authorization decisions over multiple hops. In addition you will learn about the principal architecture of a STS, how to customize the one that comes with this training course, as well as how to build your own. Outsourcing Authentication:  Windows Azure & the Azure AppFabric Access Control Service Microsoft provides a multi-tenant security token service as part of the Azure platform cloud offering. This is an interesting product because it allows to outsource vital infrastructure services to a managed environment that guarantees uptime and scalability. Another advantage of the Access Control Service is, that it allows easy integration of both the “enterprise” protocols like WS-* as well as “web identities” like LiveID, Google or Facebook into your applications. ACS acts as a protocol bridge in this case where the application developer doesn’t need to implement all these protocols, but simply uses a service to make it happen. Claims & Federation for the Web and Mobile World Also the web & mobile world moves to a token and claims-based model. While the mechanics are almost identical, other protocols and token types are used to achieve better HTTP (REST) and JavaScript integration for in-browser applications and small footprint devices. Also patterns like how to allow third party applications to work with your data without having to disclose your credentials are important concepts in these application types. The nice thing about WIF and its powerful base APIs and abstractions is that it can shield application logic from these details while you can focus on implementing the actual application. HTH

Harnessing the Power of the New Release of Oracle GoldenGate 11g I would highly recommend watching the webcast to meet many new features of the new release and hear the product management team respond to the questions from the audience in a nice long Q&A section. In my blog last week I listed the media coverage for this new release. There is a new article published by ITJungle talking about Oracle GoldenGate’s heterogeneity and support for DB2 for iSeries: Oracle Completes DB2/400 Support in Data Replication Tool As mentioned in last week’s blog, we received over 150 questions from the audience and in this blog I'd like to continue to post some of the frequently asked,  questions and their answers: Question: What are the fundamental differences between classic data capture and integrated data capture? Do both use the redo logs in the source database? Answer: Yes, they both use redo logs. Classic capture parses the redo log data directly, whereas the Integrated Capture lets the Oracle database parse the redo log record using an internal API. Question: Does GoldenGate version need to match Oracle Database version? Answer: No, they are not directly linked. Oracle GoldenGate 11g Release 2 supports Oracle Database version 10gR2 as well. For Oracle Database version 10gR1 and Oracle Database version 9i you will need GoldenGate11g Release 1 or lower. And for Oracle Database 8i you need Oracle GoldenGate 10 or earlier versions. Question: If I already use Data Guard, do I need GoldenGate? Answer: Data Guard is designed as the best disaster recovery solution for Oracle Database. If you would like to implement a bidirectional Active-Active replication solution or need to move data between heterogeneous systems, you will need GoldenGate. Question: On Compression and GoldenGate, if the source uses compression, is it required that the target also use compression? Answer: No, the source and target do not need to have the same compression settings. Question: Does GG support Advance Security Option on the Source database? Answer: Yes it does. Question: Can I use GoldenGate to upgrade the Oracle Database to 11g and do OS migration at the same time? Answer: Yes, this is a very common project where GoldenGate can eliminate downtime, give flexibility to test the target as needed, and minimize risks with fail-back option to the old environment. For more information on database upgrades please check out the following white papers: Best Practices for Migrating/Upgrading Oracle Database Using Oracle GoldenGate 11g Zero-Downtime Database Upgrades Using Oracle GoldenGate Question: Does GoldenGate create any trigger in the source database table level or row level to for real-time data integration? Answer: No, GoldenGate does not create triggers. Question: Can transformation be done after insert to destination table or need to be done before? Answer: It can happen in the Capture (Extract) process, in the  Delivery (Replicat) process, or in the target database. For more resources on Oracle GoldenGate 11gR2 please check out our Oracle GoldenGate 11gR2 resource kit as well.

• Reducing Deadlocks - not a DBA issue ?

  - by steveh99999

   As a DBA, I'm involved on an almost daily basis troubleshooting 'SQL Server' performance issues. Often, this troubleshooting soon veers away from a 'its a SQL Server issue' to instead become a wider application/database design/coding issue.One common perception with SQL Server is that deadlocking is an application design issue - and is fixed by recoding...  I see this reinforced by MCP-type questions/scenarios where the answer to prevent deadlocking is simply to change the order in code in which tables are accessed....Whilst this is correct, I do think this has led to a situation where many 'operational' or 'production support' DBAs, when faced with a deadlock, are happy to throw the issue over to developers without analysing the issue further....A couple of 'war stories' on deadlocks which I think are interesting :- Case One , I had an issue recently on a third-party application that I support on SQL 2008.  This particular third-party application has an unusual support agreement where the customer is allowed to change the index design on the third-party provided database.  However, we are not allowed to alter application code or modify table structure..This third-party application is also known to encounter occasional deadlocks – indeed, I have documentation from the vendor that up to 50 deadlocks per day is not unusual !So, as a DBA I have to support an application which in my opinion has too many deadlocks - but, I cannot influence the design of the tables or stored procedures for the application. This should be the classic - blame the third-party developers scenario, and hope this issue gets addressed in a future application release - ie we could wait years for this to be resolved and implemented in our production environment...But, as DBAs  can change the index layout, is there anything I could do still to reduce the deadlocks in the application ?I initially used SQL traceflag 1222 to write deadlock detection output to the SQL Errorlog – using this I was able to identify one table heavily involved in the deadlocks.When I examined the table definition, I was surprised to see it was a heap – ie no clustered index existed on the table.Using SQL profiler to see locking behaviour and plan for the query involved in the deadlock, I was able to confirm a table scan was being performed.By creating an appropriate clustered index - it was possible to produce a more efficient plan and locking behaviour.So, less locks, held for less time = less possibility of deadlocks. I'm still unhappy about the overall number of deadlocks on this system - but that's something to be discussed further with the vendor.Case Two,  a system which hadn't changed for months suddenly started seeing deadlocks on a regular basis. I love the 'nothing's changed' scenario, as it gives me the opportunity to appear wise and say 'nothings changed on this system, except the data'.. This particular deadlock occurred on a table which had been growing rapidly. By using DBCC SHOW_STATISTICS - the DBA team were able to see that the deadlocks seemed to be occurring shortly after auto-update stats had regenerated the table statistics using it's default sampling behaviour.As a quick fix, we were able to schedule a nightly UPDATE STATISTICS WITH FULLSCAN on the table involved in the deadlock - thus, greatly reducing the potential for stats to be updated via auto_update_stats, consequently reducing the potential for a bad plan to be generated based on an unrepresentative sample of the data. This reduced the possibility of a deadlock occurring.  Not a perfect solution by any means, but quick, easy to implement, and needed no application code changes. This fix gave us some 'breathing space'  to properly fix the code during the next scheduled application release.   The moral of this post - don't dismiss deadlocks as issues that can only be fixed by developers...
