• Soft lockup after upgrade - cannot install from live CD

  - by nbm

  I dual-boot MacIntel Core 2 duo. nVidia graphics. Ran upgrade from ubuntu 13.10 to 14.04 (64 bit). On restart ran into {numbers} Bug: soft lockup - CPU#0 stuck for 22s! [swapper/0:1] Tried loading earlier kernel: same problem Tried re-installing ubuntu from a liveCD that has worked in the past: version 13.04. Same problem. Tried re-partitioning hard drive using Mac OS X disk utility and then installing ubuntu 14.04LTS from liveCD. Same problem. Not possible to verify liveCD disk (creates same "soft lockup" bug.) Tried installing from the liveCD with version 13.04 that I know works (that's how I got Ubuntu on this machine in the first place.) Same problem. I know this is not a hardware problem as OS X works just fine, I am using it right now on the same machine. I have been using various versions of Ubuntu for 2 years. Things I cannot do: Open a terminal Verify CD image Start ubuntu from CD (same soft lockup problem) This problem is similar to some other questions, none of which have been satisfactorily answered: Ubuntu 14.04 soft lockup on Vostro 3500 Cannot do fresh install of Ubuntu 13.04 while booting from DVD: "soft lockup" bug Live CD stalls when installing Ubuntu 13.10 UPDATE 6/11/14: Following some much-appreciated advice from bain (see below) I burned a 12.04LTS disk and started with kernel parameters: noapic, no1apic, acpi=off, nomodeset, elevator=deadline, and clocksource=jiffies. With all of these parameters I was able to load the 12.04LTS CD ("Try without installing"). It worked fine. However, as soon as I tried to install Ubuntu from the CD, my wired ethernet (eth0) connection would hang. There are already various askubuntu questions and bug reports about this problem, none of which had answers for me. (E.g., dhclient eth0 does nothing, none of the various reset commands does anything, manually setting IP &etc does nothing. I could reliably kill the ethernet connection by clicking "install ubuntu" every single time.) I could go ahead and install 12.04 without an internet connection, but the install would freeze after mostly completing (I tried several times.) There were some relevant error messages in the details of the install output script that, IIRC, had to do with searching for missing files and not being able to access eth0 (internet) to get them. To be honest I gave up at that point and I'm not sure I wrote those down. If I find some notes I will post them. At this point I no longer have Ubuntu on my system. I wiped the partitions and am using exclusively OS X. I am leaving this question in case it helps anyone else with similar problems. I love open source and I love Linux, and the next machine I get I will probably just build from Arch. At the moment I miss repositories and a lot of other things about Ubuntu, but the OS X terminal is 'nix, I can pretty much use all the open source apps I like, and while I am not a fan of the Apple software it gets the job done for me. Unlike Ubuntu, which can't even install. I realize this isn't necessarily a place for a soapbox speech, but when I first installed 12.04 several years ago there were already people in the community complaining that Canonical was going too "commercial". But I loved it. Several years later and all I've seen is Canonical adding more not-so-useful bells and whistles to Ubuntu while continually failing to fix basic problems on upgrades. With a dual-boot (and sometimes triple-boot) system it always took me some tweaking to get an upgrade to work, and to some extent that is okay. But at this point I feel like Canonical ought to just put a price tag on Ubuntu. All I see is more commercialism and advertising and product tie-ins, and ongoing problems do not get fixed. I am a big fan of open-source, not-for profit enterprise. I am also a big fan of for-profit enterprise, which certainly has its place and usefulness. I am not a fan of companies who pretend to be in favor of open source but really are just out to make a buck, and IMNSHO that is what Canonical has become. This is a great community and I wish you all the best, but my next install of Linux will not be Ubuntu.

• Application Composer: Exposing Your Customizations in BI Analytics and Reporting

  - by Richard Bingham

  Introduction This article explains in simple terms how to ensure the customizations and extensions you have made to your Fusion Applications are available for use in reporting and analytics. It also includes four embedded demo videos from our YouTube channel (if they don't appear check the browser address bar for a blocking shield icon). If you are new to Business Intelligence consider first reviewing our getting started article, and you can read more about the topic of custom subject areas in the documentation book Extending Sales. There are essentially four sections to this post. First we look at how custom fields added to standard objects are made available for reporting. Secondly we look at creating custom subject areas on the standard objects. Next we consider reporting on custom objects, starting with simple standalone objects, then child custom objects, and finally custom objects with relationships. Finally this article reviews how flexfields are exposed for reporting. Whilst this article applies to both Cloud/SaaS and on-premises deployments, if you are an on-premises developer then you can also use the BI Administration Tool to customize your BI metadata repository (the RPD) and create new subject areas. Whilst this is not covered here you can read more in Chapter 8 of the Extensibility Guide for Developers. Custom Fields on Standard Objects If you add a custom field to your standard object then it's likely you'll want to include it in your reports. This is very simple, since all new fields are instantly available in the "[objectName] Extension" folder in existing subject areas. The following two minute video demonstrates this. Custom Subject Areas for Standard Objects You can create your own subject areas for use in analytics and reporting via Application Composer. An example use-case could be to simplify the seeded subject areas, since they sometimes contain complex data fields and internal values that could confuse business users. One thing to note is that you cannot create subject areas in a sandbox, as it is not supported by BI, so once your custom object is tested and complete you'll need to publish the sandbox before moving forwards. The subject area creation processes is essentially two-fold. Once the request is submitted the ADF artifacts are generated, then secondly the related metadata is sent to the BI presentation server API's to make the updates there. One thing to note is that this second step may take up to ten minutes to complete. Once finished the status of the custom subject area request should show as 'OK' and it is then ready for use. Within the creation processes wizard-like steps there are three concepts worth highlighting: Date Flattening - this feature permits the roll up of reports at various date levels, such as data by week, month, quarter, or year. You simply check the box to enable it for that date field. Measures - these are your own functions that you can build into the custom subject area. They are related to the field data type and include min-max for dates, and sum(), avg(), and count() for  numeric fields. Implicit Facts - used to make the BI metadata join between your object fields and the calculated measure fields. The advice is to choose the most frequently used measure to ensure consistency. This video shows a simple example, where a simplified subject area is created for the customer 'Contact' standard object, picking just a few fields upon which users can then create reports. Custom Objects Custom subject areas support three types of custom objects. First is a simple standalone custom object and for which the same process mentioned above applies. The next is a custom child object created on a standard object parent, and finally a custom object that is related to a parent object - usually through a dynamic choice list. Whilst the steps in each of these last two are mostly the same, there are differences in the way you choose the objects and their fields. This is illustrated in the videos below.The first video shows the process for creating a custom subject area for a simple standalone custom object. This second video demonstrates how to create custom subject areas for custom objects that are of parent:child type, as well as those those with dynamic-choice-list relationships. &lt;span id=&quot;XinhaEditingPostion&quot;&gt;&lt;/span&gt; Flexfields Dynamic and Extensible Flexfields satisfy a similar requirement as custom fields (for Application Composer), with flexfields common across the Fusion Financials, Supply Chain and Procurement, and HCM applications. The basic principle is when you enable and configure your flexfields, in the edit page under each segment region (for both global and context segments) there is a BI Enabled check box. Once this is checked and you've completed your configuration, you run the Scheduled Process job named 'Import Oracle Fusion Data Extensions for Transactional Business Intelligence' to generate and migrate the related BI artifacts and data. This applies for dynamic, key, and extensible flexfields. Of course there is more to consider in terms of how you wish your flexfields to be implemented and exposed in your reports, and details are given in Chapter 4 of the Extending Applications guide.

• Thinking differently about BI delivery

  - by jamiet

  My day job involves implementing Business Intelligence (BI) solutions which, as I have said before, is simply about giving people the information they need to do their jobs. I’m always interested in learning about new ways of achieving that aim and that is my motivation for writing blog entries that are not concerned with SQL or SQL Server per se. Implementing BI systems usually involves hacking together a bunch third party products with some in-house “glue” and delivering information using some shiny, expensive web-based front-end tool; the list of vendors that supply such tools is big and ever-growing. No doubt these tools have their place and of late I have started to wonder whether they can be supplemented with different ways of delivering information. The problem I have with these separate web-based tools is exactly that – they are separate web-based tools. What’s the problem with that you might ask? I’ll explain! They force the information worker to go somewhere unfamiliar in order to get the information they need to do their jobs. Would it not be better if we could deliver information into the tools that those information workers are already using and not force them to go somewhere else? I look at the rise of blogging over recent years and I realise that what made them popular is that people can subscribe to RSS feeds and have information pushed to them in their tool of choice rather than them having to go and find the information for themselves in a tool that has been foisted upon them. Would it not be a good idea to adopt the principle of subscription for the benefit of delivering BI information as well? I think it would and in the rest of this blog entry I’ll outline such a scenario where the power of subscription could be used to enhance the delivery of information to information workers. Typical questions that information workers ask might be: What are my year-on-year sales figures? What was my footfall yesterday? How many widgets have I sold so far today? Each of those questions includes a time element and that shouldn’t surprise us, any BI system that I have worked on includes the dimension of time. Now, what do people use to view and organise their time-oriented information? Its not a trick question, they use a calendar and in the enterprise space more often than not that calendar is managed using Outlook. Given then that information workers are already looking at their calendar in Outlook anyway would it not make sense then to deliver information into that same calendar? Of course it would. Calendars are a great way of visualising information such as sales figures. Observe: Just in this single screenshot I have managed to convey a multitude of information. The information worker can see, at a glance, information about hourly/daily/weekly/monthly sales and, moreover, he/she is viewing that information right inside the tool that they use every day. There is no effort on the part of him/her, the information just appears hour after hour, day after day. Taking the idea further, each one of those calendar items could be a mini-dashboard in its own right. Double-clicking on an item could show a plethora of other information about that time slot such as breaking the sales down per region or year-over-year comparisons. Perhaps the title could employ a sparkline? Loads of possibilities. The point is that calendars are a completely natural way to visualise information; we should make more use of them! The real beauty of delivering information using calendars for us BI developers is that it should be so easy. In the case of Outlook we don’t need to write complicated VBA code that can go and manipulate a person’s calendar, simply publishing data in a format that Outlook can understand is sufficient and happily such formats already exist; iCalendar is the accepted format and the even more flexible xCalendar is hopefully on its way as well.   I’d like to make one last point and this one is with my SQL Server hat on. Reporting Services 2008 R2 introduced the ability to publish data as subscribable Atom feeds so it seems logical that it could also be a vehicle for delivering calendar feeds too. If you think this would be a good idea go and vote for it at Publish data as iCalendar feeds and please please please add some comments (especially if you vote it down). Work smarter, not harder! @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Synergy - easy share of keyboard and mouse between multiple computers

  Did you ever have the urge to share one set of keyboard and mouse between multiple machines? If so, please read on... Using multiple machines Honestly, as a software craftsman it is my daily business to run multiple machines - either physical or virtual - to be able to solve my customers' requirements. Recent hardware equipment allows this very easily. For laptops it's a no-brainer to attach a second or even a third screen in order to extend your native display. This works quite handy and in my case I used to attached two additional screens - one via HD15 connector, the other via HDMI. But... as it's a laptop and therefore a mobile unit there are slight restrictions. Detaching and re-attaching all cables when changing locations is one of them but hardware limitations, too. After all, it's a laptop and not a workstation. I guess, that anyone working in IT (or ICT) has more than one machine at their workplace or their home office and at least I find it quite annoying to have multiple sets of keyboard and mouse conquering my remaining space on my desk. Despite the ugly looks of all those cables and whatsoever 'chaos of distraction' I prefer a more clean solution and working environment. This allows me to actually focus on my work and tasks to do rather than to worry about choosing the right combination of keyboard/mouse. My current workplace is a patch work of various pieces of hardware (approx. 2-3 years): DIY desktop on Ubuntu 12.04 64-bit, Core2 Duo (E7400, 2.8GHz), 4GB RAM, 2x 250GB HDD, nVidia GPU 512MB Dell Inspiron 1525 on Windows 8 64-bit, 4GB RAM, 200GB HDD HP Compaq 6720s on Windows Vista 32-bit, Core2 Duo (T5670, 1.8GHz), 2GB RAM, 160GB HDD Mac mini on Mac OS X 10.7, Core i5 (2.3 GHz), 2GB RAM, 500GB HDD I know... Not the latest and greatest but a decent combination to work with. New system(s) is/are already on the shopping list but I live in the 'wrong' country to buy computer hardware. So, the next trip abroad will provide me with some new stuff. Using multiple operating systems The list of hardware above already names different operating systems, and actually I have only one preference: Linux. But still my job as a software craftsman for Visual FoxPro and .NET development requires other OSes, too. Not a big deal, it's just like this. Additionally to those physical machines, there are a bunch of virtual machines around. Most of them running either Windows XP or Windows 7. Since years I have the practice that each development for one customer is isolated into its own virtual machine and environment. This keeps it clean and version-safe. But as you can easily imagine with that setup there are a couple of constraints referring to keyboard and mouse. Usually, those systems require their own pieces of hardware attached. As stated, I don't like clutter on my desk's surface, so a cross-platform solution has to come in here. In the past, I tried it with various applications, hardware or network protocols like X11, RDP, NX, TeamViewer, RAdmin, KVM switch, etc. but the problem in this case is that they either allow you to remotely connect to the other system or exclusively 'bind' your peripherals to the active system. Not optimal after all. Synergy to the rescue Quote from their website: "Synergy lets you easily share your mouse and keyboard between multiple computers on your desk, and it's Free and Open Source. Just move your mouse off the edge of one computer's screen on to another. You can even share all of your clipboards. All you need is a network connection. Synergy is cross-platform (works on Windows, Mac OS X and Linux)." Yep, that's it! All I need for my setup here... Actually, I couldn't believe it myself that I didn't stumble over synergy earlier but 'Get over it' and there we go. And despite the fact that it is Open Source, no, it's also for free. Donations for the developers are very welcome and recently they introduced Synergy Premium. A possibility to buy so-called premium votes that can be used to put more weight / importance on specific issues or bugs that you would like the developers to look into. Installation and configuration Simply download the installation packages for your systems of choice, run the installer and enter some minor information about your network setup. I chose my desktop machine for the role of the Synergy server and configured my screen setup as follows: The screen setup allows you currently to build or connect up to 15 machines. The number of screens can be higher as those machine might have multiple screens physically attached. Synergy takes this into the overall calculations and simply works as expected. I tried it for fun with a second monitor each connected to both laptops to have a total number of 6 active screens. No flaws after all - stunning! All the other machines are configured as clients like so: Side note: The screenshot was taken on Windows 8 and pasted via clipboard into Gimp running on Ubuntu. Resume Synergy is now definitely in my box of tools for my daily work, and amongst the first pieces of software I install after the operating system. It just simplifies my life and cleans my desk. Never again without Synergy!Now, only waiting for an Android version to integrate my Galaxy Tab 10.1, too. ;-) Please, check out that superb product and enjoy sharing one keyboard, one mouse and one clipboard between your various machines and operating systems.

• What Counts for A DBA - Logic

  - by drsql

  "There are 10 kinds of people in the world. Those who will always wonder why there are only two items in my list and those who will figured it out the first time they saw this very old joke."  Those readers who will give up immediately and get frustrated with me for not explaining it to them are not likely going to be great technical professionals of any sort, much less a programmer or administrator who will be constantly dealing with the common failures that make up a DBA's day.  Many of these people will stare at this like a dog staring at a traffic signal and still have no more idea of how to decipher the riddle. Without explanation they will give up, call the joke "stupid" and, feeling quite superior, walk away indignantly to their job likely flipping patties of meat-by-product. As a data professional or any programmer who has strayed  to this very data-oriented blog, you would, if you are worth your weight in air, either have recognized immediately what was going on, or felt a bit ignorant.  Your friends are chuckling over the joke, but why is it funny? Unfortunately you left your smartphone at home on the dresser because you were up late last night programming and were running late to work (again), so you will either have to fake a laugh or figure it out.  Digging through the joke, you figure out that the word "two" is the most important part, since initially the joke mentioned 10. Hmm, why did they spell out two, but not ten? Maybe 10 could be interpreted a different way?  As a DBA, this sort of logic comes into play every day, and sometimes it doesn't involve nerdy riddles or Star Wars folklore.  When you turn on your computer and get the dreaded blue screen of death, you don't immediately cry to the help desk and sit on your thumbs and whine about not being able to work. Do that and your co-workers will question your nerd-hood; I know I certainly would. You figure out the problem, and when you have it narrowed down, you call the help desk and tell them what the problem is, usually having to explain that yes, you did in fact try to reboot before calling.  Of course, sometimes humility does come in to play when you reach the end of your abilities, but the ‘end of abilities’ is not something any of us recognize readily. It is handy to have the ability to use logic to solve uncommon problems: It becomes especially useful when you are trying to solve a data-related problem such as a query performance issue, and the way that you approach things will tell your coworkers a great deal about your abilities.  The novice is likely to immediately take the approach of  trying to add more indexes or blaming the hardware. As you become more and more experienced, it becomes increasingly obvious that performance issues are a very complex topic. A query may be slow for a myriad of reasons, from concurrency issues, a poor query plan because of a parameter value (like parameter sniffing,) poor coding standards, or just because it is a complex query that is going to be slow sometimes. Some queries that you will deal with may have twenty joins and hundreds of search criteria, and it can take a lot of thought to determine what is going on.  You can usually figure out the problem to almost any query by using basic knowledge of how joins and queries work, together with the help of such things as the query plan, profiler or monitoring tools.  It is not unlikely that it can take a full day’s work to understand some queries, breaking them down into smaller queries to find a very tiny problem. Not every time will you actually find the problem, and it is part of the process to occasionally admit that the problem is random, and everything works fine now.  Sometimes, it is necessary to realize that a problem is outside of your current knowledge, and admit temporary defeat: You can, at least, narrow down the source of the problem by looking logically at all of the possible solutions. By doing this, you can satisfy your curiosity and learn more about what the actual problem was. For example, in the joke, had you never been exposed to the concept of binary numbers, there is no way you could have known that binary - 10 = decimal - 2, but you could have logically come to the conclusion that 10 must not mean ten in the context of the joke, and at that point you are that much closer to getting the joke and at least won't feel so ignorant.

• OIM 11g - Multi Valued attribute reconciliation of a child form

  - by user604275

  This topic gives a brief description on how we can do reconciliation of a child form attribute which is also multi valued from a flat file . The format of the flat file is (an example): ManagementDomain1|Entitlement1|DIRECTORY SERVER,EMAIL ManagementDomain2|Entitlement2|EMAIL PROVIDER INSTANCE - UMS,EMAIL VERIFICATION In OIM there will be a parent form for fields Management domain and Entitlement.Reconciliation will assign Servers ( which are multi valued) to corresponding Management  Domain and Entitlement .In the flat file , multi valued fields are seperated by comma(,). In the design console, Create a form with 'Server Name' as a field and make it a child form . Open the corresponding Resource Object and add this field for reconcilitaion.While adding , choose 'Multivalued' check box. (please find attached screen shot on how to add it , Child Table.docx) Open process definiton and add child form fields for recociliation. Please click on the 'Create Reconcilitaion Profile' buttton on the resource object tab. The API methods used for child form reconciliation are : 1.           reconEventKey =   reconOpsIntf.createReconciliationEvent(resObjName, reconData,                                                            false); ·                                    ‘False’  here tells that we are creating the recon for a child table . 2.               2.       reconOpsIntf.providingAllMultiAttributeData(reconEventKey, RECON_FIELD_IN_RO, true);                RECON_FIELD_IN_RO is the field that we added in the Resource Object while adding for reconciliation, please refer the screen shot) 3.    reconOpsIntf.addDirectBulkMultiAttributeData(reconEventKey,RECON_FIELD_IN_RO, bulkChildDataMapList);                 bulkChildDataMapList  is coded as below :                 List<Map> bulkChildDataMapList = new ArrayList<Map>();                   for (int i = 0; i < stokens.length; i++) {                            Map<String, String> attributeMap = new HashMap<String, String>();                           String serverName = stokens[i].toUpperCase();                           attributeMap.put("Server Name", stokens[i]);                           bulkChildDataMapList.add(attributeMap);                         } 4                  4.       reconOpsIntf.finishReconciliationEvent(reconEventKey); 5.       reconOpsIntf.processReconciliationEvent(reconEventKey); Now, we have to register the plug-in, import metadata into MDS and then create a scheduled job to execute which will run the reconciliation.

• BizTalk: namespaces

  - by Leonid Ganeline

  BizTalk team did a good job hiding the .NET guts from developers. Developers are working with editors and hardly with .NET code. The Orchestration editor, the Mapper, the Schema editor, the Pipeline editor, all these editors hide what is going on with artifacts created and deployed. Working with the BizTalk artifacts year after year brings us some knowledge which could help to understand more about the .NET guts. I would like to highlight the .NET namespaces. What they are, how they influence our everyday tasks in the BizTalk application development. What is it? Most of the BizTalk artifacts are compiled into the NET classes. Not all of them… but I will show you later. Classes are placed inside the namespaces. I will not describe here why we need namespaces and what is it. I assume you all know about it more then me. Here I would like to emphasize that almost each BizTalk artifact is implemented as a .NET class within a .NET namespace. Where to see the namespaces in development? The namespaces are inconsistently spread across the artifact parameters. Let’s start with namespace placement in development. Then we go with namespaces in deployment and operations. I am using pictures from the BizTalk Server 2013 Beta and the Visual Studio 2012 but there was no changes regarding the namespaces starting from the BizTalk 2006. Default namespace When a new BizTalk project is created, the default namespace is set up the same as a name of a project. This namespace would be used for all new BizTalk artifacts added to this project. Orchestrations When we select a green or a red markers (the Begin and End orchestration shapes) we will see the orchestration Properties window. We also can click anywhere on the space between Port Surfaces to see this window.   Schemas The only way to see the NET namespace for map is selecting the schema file name into the Solution Explorer. Notes: We can also see the Type Name parameter. It is a name of the correspondent .NET class. We can also see the Fully Qualified Name parameter. We cannot see the schema namespace when selecting any node on the schema editor surface. Only selecting a schema file name gives us a namespace parameter. If we select a <Schema> node we can get the Target Namespace parameter of the schema. This is NOT the .NET namespace! It is an XML namespace. See this XML namespace inside the XML schema, it is shown as a special targetNamespace attribute Here this XML namespace appears inside the XML document itself. It is shown as a special xmlns attribute.   Maps It is similar to the schemas. The only way to see the NET namespace for map is selecting a map file name into the Solution Explorer. Pipelines It is similar to the schemas. The only way to see the NET namespace for pipeline is selecting a pipeline file name into the Solution Explorer. z Ports, Policies and Tracking Profiles The Send and Receive Ports, the Policies and the BAM Tracking Profiles do not create the .NET classes and they do not have the associated .NET namespaces. How to copy artifacts? Since the new versions of the BizTalk Server are going to production I am spending more and more time redesigning and refactoring the BizTalk applications. It is good to know how the refactoring process copes with the .NET namespaces. Let see what is going on with the namespaces when we copy the artifacts from one project to another. Here is an example: I am going to group the artifacts under the project folders. So, I have created a Group folder, have run the Add / Existing Item.. command and have chosen all artifacts in the project root. The artifact copies were created in the Group folder: What was happened with the namespaces of the artifacts? As you can see, the folder name, the “Group”, was added to the namespace. It is great! When I added a folder, I have added one more level in the name hierarchy and the namespace change just reflexes this hierarchy change.  The same namespace adjustment happens when we copy the BizTalk artifacts between the projects. But there is an issue with the namespace of an orchestration. It was not changed. The namespaces of the schemas, maps, pipelines are changed but not the orchestration namespace. I have to change the orchestration namespace manually. Now another example: I am creating a new Project folder and moving the artifacts there from the project root by drag and drop. We will mention the artifact namespaces are not changed. Another example: I am copying the artifacts from the project root by (drag and drop) + Ctrl. We will mention the artifact namespaces are changed. It works exactly as it was with the Add / Existing Item.. command. Conclusion: The namespace parameter is put inconsistently in different places for different artifacts Moving artifacts changes the namespaces of the schemas, maps, pipelines but not the orchestrations.

• The design of a generic data synchronizer, or, an [object] that does [actions] with the aid of [helpers]

  - by acheong87

  I'd like to create a generic data-source "synchronizer," where data-source "types" may include MySQL databases, Google Spreadsheets documents, CSV files, among others. I've been trying to figure out how to structure this in terms of classes and interfaces, keeping in mind (what I've read about) composition vs. inheritance and is-a vs. has-a, but each route I go down seems to violate some principle. For simplicity, assume that all data-sources have a header-row-plus-data-rows format. For example, assume that the first rows of Google Spreadsheets documents and CSV files will have column headers, a.k.a. "fields" (to parallel database fields). Also, eventually, I would like to implement this in PHP, but avoiding language-specific discussion would probably be more productive. Here's an overview of what I've tried. Part 1/4: ISyncable class CMySQL implements ISyncable GetFields() // sql query, pdo statement, whatever AddFields() RemFields() ... _dbh class CGoogleSpreadsheets implements ISyncable GetFields() // zend gdata api AddFields() RemFields() ... _spreadsheetKey _worksheetId class CCsvFile implements ISyncable GetFields() // read from buffer AddFields() RemFields() ... _buffer interface ISyncable GetFields() AddFields($field1, $field2, ...) RemFields($field1, $field2, ...) ... CanAddFields() // maybe the spreadsheet is locked for write, or CanRemFields() // maybe no permission to alter a database table ... AddRow() ModRow() RemRow() ... Open() Close() ... First Question: Does it make sense to use an interface, as above? Part 2/4: CSyncer Next, the thing that does the syncing. class CSyncer __construct(ISyncable $A, ISyncable $B) Push() // sync A to B Pull() // sync B to A Sync() // Push() and Pull() only differ in direction; factor. // Sync()'s job is to make sure that the fields on each side // match, to add fields where appropriate and possible, to // account for different column-orderings, etc., and of // course, to add and remove rows as necessary to sync. ... _A _B Second Question: Does it make sense to define such a class, or am I treading dangerously close to the "Kingdom of Nouns"? Part 3/4: CTranslator? ITranslator? Now, here's where I actually get lost, assuming the above is passable. Sometimes, two ISyncables speak different "dialects." For example, believe it or not, Google Spreadsheets (accessed through the Google Data API "list feed") returns column headers lower-cased and stripped of all spaces and symbols! That is, sys_TIMESTAMP is systimestamp, as far as my code can tell. (Yes, I am aware that the "cell feed" does not strip the name so; however cell-by-cell manipulation is too slow for what I'm doing.) One can imagine other hypothetical examples. Perhaps even the data itself can be in different "dialects." But let's take it as given for now, and not argue this if possible. Third Question: How would you implement "translation"? Note: Taking all this as an exercise, I'm more interested in the "idealized" design, rather than the practical one. (God knows that shipped sailed when I began this project.) Part 4/4: Further Thought Here's my train of thought to demonstrate I've thunk, albeit unfruitfully: First, I thought, primitively, "I'll just modify CMySQL::GetFields() to lower-case and strip field names so they're compatible with Google Spreadsheets." But of course, then my class should really be called, CMySQLForGoogleSpreadsheets, and that can't be right. So, the thing which translates must exist outside of an ISyncable implementor. And surely it can't be right to make each translation a method in CSyncer. If it exists outside of both ISyncable and CSyncer, then what is it? (Is it even an "it"?) Is it an abstract class, i.e. abstract CTranslator? Is it an interface, since a translator only does, not has, i.e. interface ITranslator? Does it even require instantiation? e.g. If it's an ITranslator, then should its translation methods be static? (I learned what "late static binding" meant, today.) And, dear God, whatever it is, how should a CSyncer use it? Does it "have" it? Is it, "it"? Who am I? ...am I, "I"? I've attempted to break up the question into sub-questions, but essentially my question is singular: How does one implement an object A that conceptually "links" (has) two objects b1 and b2 that share a common interface B, where certain pairs of b1 and b2 require a helper, e.g. a translator, to be handled by A? Something tells me that I've overcomplicated this design, or violated a principle much higher up. Thank you all very much for your time and any advice you can provide.

• What are the industry metrics for average spend on dev hardware and software? [on hold]

  - by RationalGeek

  I'm trying to budget for my dev shop and compare our budget items to industry expectations. I'm hoping to find some information on what percentage of a dev's salary is generally spent on tooling, both hardware and software. Where can I find such information? If instead there is a source that looks at raw dollars that is useful, too. I can extrapolate what I need from that. NOTE: Your anecdotal evidence from your own job will not be very helpful. I'm looking for industry average statistics from a credible source. EDIT: I'm reluctant to even keep this question going based on the passionate negative responses of commenters, but I do think this is valuable information (assuming anyone will care to answer) so let me make one attempt to clarify why I'm looking for this information, and then leave it at that. I'm not sure why understanding and validating my motives is a necessary step to providing the information, but apparently that is the case, so I will do my best. Firstly, let me respond to the idea that us "management types" shouldn't use these types of metrics to evaluate budgets. I agree in part. Ideally, you should spend whatever is necessary on developers in order to keep them fully happy and productive. And this is true of all employees. However, companies operate in a world of limited resources, and every dollar spent in one area means a dollar not spent in another. So it is not enough to simply say "I need to spend $10,000 per developer next year" without having some way to justify that position. One way to help justify it is to compare yourself against the industry. If it is the case that on average a software shops spends 5% (making up that number) of their total development budget (salaries being the large portion of the other 95%, for arguments sake), and I'm only spending 3%, it helps in the justification process. So, it is not my intent to use this information to limit what I spend on developers, but rather to arm myself with the necessary justification to spend what I need to spend on developers to give them the best tools I can. I have been a developer for many years and I understand the need for proper tooling. Next, let's examine the idea that even considering the relationship between a spend on developer salaries and developer tooling is ludicrous and should be banned from budgetary thinking. As Jimmy Hoffa put it in their comment, it's like saying "I'm going to spend no more than 10% of median employee salary on light bulbs and coffee from now on.". Well, yes, it is like saying that, and from a budgeting perspective, this is a useful way to look at things. If you know that, on average, an employee consumes X dollars of coffee a year, then you can project a coffee budget based on that. And you can compare it to an industry metric to understand where you fall: do you spend more on coffee than other companies or less? Why might this be? If you are a coffee supply manager, that seems like a useful thought process. The same seems to hold true for developers. Now, on to the idea that I need to compare "apples to apples" and only look at other shops that are in the same place geographically, the same business, the same application architecture, and the same development frameworks. I guess if I could find such a statistic that said "a shop that is exactly identical to yours spends X on developer tooling" it would be wonderful. But there is plenty of value in an average statistic. Here's an analogy: let's say you are working on a household budget and need to decide how much to spend on groceries. Is it enough to know that the average consumer spends 15% on groceries and therefore decide that you will budget exactly 15%? No. You have to tweak your budget based on your individual needs and situation. But the generalized statistic does help in this evaluation. You can know if your budget is grossly off from what others are doing, and this can help you figure out why this is. So, I will concede the point that it would be better to find statistics that align to my shop, though I think any statistics I could find would be useful for what I'm doing. In that light, let's say that my shop is mostly focused on ASP.NET web applications. That doesn't map perfectly to reality because large enterprises have very heterogenous IT environments. But if I was going to pick one technology that is our focus that would be it. But, if you were to point me at some statistics that are related to a Linux shop doing embedded Java applications, I would still find it useful as a point of comparison. SUMMARY: Let me try to rephrase my question. I'm trying to find industry metrics on how much dev shops spend on developer tooling, both hardware and software. I don't so much care whether it is expressed as a percentage of total budget or as X dollars per dev or as Y percentage of salary. Any metric would be useful. If there are metrics that are specific to ASP.NET dev shops in the Northeast US, all the better, but I would be happy to find anything.

• 2012&ndash;The End Of The World Review

  - by Tim Murphy

  The end of the world must be coming.  Not because the Mayan calendar says so, but because Microsoft is innovating more than Apple.  It has been a crazy year, with pundits declaring not that the end of the world is coming, but that the end of Microsoft is coming.  Let’s take a look at what 2012 has brought us. The beginning of year is a blur.  I managed to get to TechEd in June which was the first time that I got to take a deep dive into Windows 8 and many other things that had been announced in 2011.  The promise I saw in these products was really encouraging.  The thought of being able to run Windows 8 from a thumb drive or have Hyper-V native to the OS told me that at least for developers good things were coming. I finally got my feet wet with Windows 8 with the developer preview just prior to the RTM.  While the initial experience was a bit of a culture shock I quickly grew to love it.  The media still seems to hold little love for the “reimagined” platform, but I think that once people spend some time with it they will enjoy the experience and what the FUD mongers say will fade into the background.  With the launch of the OS we finally got a look at the Surface.  I think this is a bold entry into the tablet market.  While I wish it was a little more affordable I am already starting to see them in the wild being used by non-techies. I was waiting for Windows Phone 8 at least as much as Windows 8, probably more.  The new hardware, better marketing and new OS features I think are going to finally push us to the point of having a real presence in the smartphone market.  I am seeing a number of iPhone users picking up a Nokia Lumia 920 and getting rid of their brand new iPhone 5.  The only real debacle that I saw around the launch was when they held back the SDK from general developers. Shortly after the launch events came Build 2012.  I was extremely disappointed that I didn’t make it to this year’s Build.  Even if they weren’t handing out Surface and Lumia devices I think the atmosphere and content were something that really needed to be experience in person.  Hopefully there will be a Build next year and it’s schedule will be announced soon.  As you would expect Windows 8 and Windows Phone 8 development were the mainstay of the conference, but improvements in Azure also played a key role.  This movement of services to the cloud will continue and we need to understand where it best fits into the solutions we build. Lower on the radar this year were Office 2013, SQL Server 2012, and Windows Server 2012.  Their glory stolen by the consumer OS and hardware announcements, these new releases are no less important.  Companies will see significant improvements in performance and capabilities if they upgrade.  At TechEd they had shown some of the new features of Windows Server 2012 around hardware integration and Hyper-V performance which absolutely blew me away.  It is our job to bring these important improvements to our company’s attention so that they can be leveraged. Personally, the consulting business in 2012 was the busiest it has been in a long time.  More companies were ready to attack new projects after several years of putting them on the back burner.  I also worked to bring back momentum to the Chicago Information Technology Architects Group.  Both the community and clients are excited about the new technologies that have come out in 2012 and now it is time to deliver. What does 2013 have in store.  I don’t see it be quite as exciting as 2012.  Microsoft will be releasing the Surface Pro in January and it seems that we will see more frequent OS update for Windows.  There are rumors that we may see a Surface phone in 2013.  It has also been announced that there will finally be a rework of the XBox next fall.  The new year will also be a time for us in the development community to take advantage of these new tools and devices.  After all, it is what we build on top of these platforms that will attract more consumers and corporations to using them. Just as I am 99.999% sure that the world is not going to end this year, I am also sure that Microsoft will move on and that most of this negative backlash from the media is actually fear and jealousy.  In the end I think we have a promising year ahead of us. del.icio.us Tags: Microsoft,Pundits,Mayans,Windows 8,Windows Phone 8,Surface

• IE9, LightSwitch Beta 2 and Zune HD: A Study in Risk Management?

  - by andrewbrust

  Photo by parl, 'Risk.’ Under Creative Commons Attribution-NonCommercial-NoDerivs License This has been a busy week for Microsoft, and for me as well.  On Monday, Microsoft launched Internet Explorer 9 at South by Southwest (SXSW) in Austin, TX.  That evening I flew from New York to Seattle.  On Tuesday morning, Microsoft launched Visual Studio LightSwitch, Beta 2 with a Go-Live license, in Redmond, and I had the privilege of speaking at the keynote presentation where the announcement was made.  Readers of this blog know I‘m a fan of LightSwitch, so I was happy to tell the app dev tools partners in the audience that I thought the LightSwitch extensions ecosystem represented a big opportunity – comparable to the opportunity when Visual Basic 1.0 was entering its final beta roughly 20 years ago.  On Tuesday evening, I flew back to New York (and wrote most of this post in-flight). Two busy, productive days.  But there was a caveat that impacts the accomplishments, because Monday was also the day reports surfaced from credible news agencies that Microsoft was discontinuing its dedicated Zune hardware efforts.  While the Zune brand, technology and service will continue to be a component of Windows Phone and a piece of the Xbox puzzle as well, speculation is that Microsoft will no longer be going toe-to-toe with iPod touch in the portable music player market. If we take all three of these developments together (even if one of them is based on speculation), two interesting conclusions can reasonably be drawn, one good and one less so. Microsoft is doubling down on technologies it finds strategic and de-emphasizing those that it does not.  HTML 5 and the Web are strategic, so here comes IE9, and it’s a very good browser.  Try it and see.  Silverlight is strategic too, as is SQL Server, Windows Azure and SQL Azure, so here comes Visual Studio LightSwitch Beta 2 and a license to deploy its apps to production.  Downloads of that product have exceeded Microsoft’s projections by more than 50%, and the company is even citing analyst firms’ figures covering the number of power-user developers that might use it. (I happen to think the product will be used by full-fledged developers as well, but that’s a separate discussion.) Windows Phone is strategic too…I wasn’t 100% positive of that before, but the Nokia agreement has made me confident.  Xbox as an entertainment appliance is also strategic.  Standalone music players are not strategic – and even if they were, selling them has been a losing battle for Microsoft.  So if Microsoft has consolidated the Zune content story and the ZunePass subscription into Xbox and Windows Phone, it would make sense, and would be a smart allocation of resources.  Essentially, it would be for the greater good. But it’s not all good.  In this scenario, Zune player customers would lose out.  Unless they wanted to switch to Windows Phone, and then use their phone’s battery for the portable media needs, they’re going to need a new platform.  They’re going to feel abandoned.  Even if Zune lives, there have been other such cul de sacs for customers.  Remember SPOT watches?  Live Spaces?  The original Live Mesh?  Microsoft discontinued each of these products.  The company is to be commended for cutting its losses, as admitting a loss isn’t easy.  But Redmond won’t be well-regarded by the victims of those decisions.  Instead, it gets black marks. What’s the answer?  I think it’s a bit like the 1980’s New York City “don’t block the box” gridlock rules: don’t enter an intersection unless you see a clear path through it.  If the light turns red and you’re blocking the perpendicular traffic, that’s your fault in judgment.  You get fined and get points on your license and you don’t get to shrug it off as beyond your control.  Accountability is key.  The same goes for Microsoft.  If it decides to enter a market, it should see a reasonable path through success in that market. Switching analogies, Microsoft shouldn’t make investments haphazardly, and it certainly shouldn’t ask investors to buy into a high-risk fund that is sold as safe and which offers only moderate returns.  People won’t continue to invest with a fund manager with a track record of over-zealous, imprudent, sub-prime investments.  The same is true on the product side for Microsoft, and not just with music players and geeky wrist watches.  It’s true of Web browsers, and line-of-business app dev tools, and smartphones, and cloud platforms and operating systems too.  When Microsoft is casual about its own risk, it raises risk for its customers, and weakens its reputation, market share and credibility.  That doesn’t mean all risk is bad, but it does mean no product team’s risk should be taken lightly. For mutual fund companies, it’s the CEO’s job to give his fund managers autonomy, but to make sure they’re conforming to a standard of rational risk management.  Because all those funds carry the same brand, and many of them serve the same investors. The same goes for Microsoft, its product portfolio, its executive ranks and its product managers.

• Are there Negative Impact of opensource on commercial environment?

  - by Lostsoul

  I know this is not a good fit for Stack Overflow but wasn't sure if it was good for this site also so let me know if its not and I'll delete it. I love programming for fun but my role in my company is not technical. I have always loved the hacker culture and have been trying to drive that openness within my company from day one. My company has a very broad range of products and there are a few that are not strategic to us so I wanted to open source them (so we can focus on what makes us unique and open source the products that every firm has). Our industry does not open source(we would be the first firm to try this) and the feedback I'm getting from my management team is either 1) we'll destroy the industry or 2) all competitive commercial firms will unite against us and we'll be wiped out either way. I disagreed on both points because I think transparency will only grow our industry and our firm (think of McDonalds/KFC sharing their recipe openly, people may copy you, competitors may target you, but customers also may feel more comfortable buying your product. The value add, I believe, is in the delivery and experience not in hoarding the recipe). It's a big battle in my firm right now between the IT people who have seen the positive effects of sharing and the business people who think we'll be giving up everything (they prefer we sell parts we want to opensource, but in their defense this is standard when divesting something). Our industry is very secretive and I don't want to put anyone(even my competitors employees) out of a job yet I don't want to protect inefficient people by not being open with everyone. Yet I've seen so many amazing technologies created in interesting ways just by giving people freedom to take apart code and put it back together. I'm interested in hearing people's thoughts(doesn't have to be to my specific situation, I'm looking for the general lessons). Its a very stressful decision(but one I feel I must make) because if we go the open source route then there will be no going back. So what are your thoughts? Does open sourcing apply generally or is it only really applicable to software? Is it overall good for people in the industry and outside? I'm actually more interested in the negativeness effects(although positive are welcomed as well) Update: Long story short, although code is involved this is not so much about code as it is more about the idea of open sourcing. We are a mid sized quant hedge fund. We have some unique strategies but also have the standard long/short, arbitrage, global macro, etc.. funds. We are keeping the unique funds we have but the other stuff that everyone else has we are considering open sourcing (We have put in years of work & millions of dollars into. Our funds is pretty popular and our performance is either in first or second quartile so I suspect there will be interest but I don't know to what extent). The goal is not to get a community to work for us or anything, the goal is to let anyone who wants to tinker with it do so and create anything they want (it will not be part of our product line although I may unofficially allocate some our of staff's time to assist any community that grows). Although the code base is quite large, the value in this is the industry knowledge and approaches we have acquired (there are many books on artificial intelligence and quant trading but they are often years behind what's really going on as most firms forbid their staff from discussing what they are doing). We are also considering after we move our clients out to let the software still run and output the resulting portfolios for free as well so people can at least see the results(as long as we have avail. infrastructure). I think our main choices are, we can continue to fight for market share in a products that are becoming commoditized, we can shut the funds/products down(and keep the code but no one outside of our firm will ever learn from it) or we can open source it and let people do what they want. By open sourcing it, my idea is that the talent pool in the industry will grow because right now most of our hires have the same background (CFA, MBA, similar school, same experience,etc.. because we can't spend time training people so the industry 'standardizes' most people and thus the firms themselves start to look/act similar) but this may allow us to identify talent that has never been in the industry before (if we put a GPU license then as people learn from what we did, we can learn from what they do as well and maybe apply it to other areas of our firm). I see a lot of benefits but not many negatives while my peers at the company see the opposite.

• To Make Diversity Work, Managers Must Stop Ignoring Difference

  - by HCM-Oracle

  By Kate Pavao - Originally posted on Profit Executive coaches Jane Hyun and Audrey S. Lee noticed something during their leadership development coaching and consulting: Frustrated employees and overwhelmed managers. “We heard from voices saying, ‘I wish my manager understood me better’ or ‘I hope my manager would take the time to learn more about me and my background,’” remembers Hyun. “At the same token, the managers we were coaching had a hard time even knowing how to start these conversations.”  Hyun and Lee wrote Flex to address some of the fears managers have when it comes to leading diverse teams—such as being afraid of offending their employees by stumbling into sensitive territory—and also to provide a sure-footed strategy for becoming a more effective leader. Here, Hyun talks about what it takes to create innovate and productive teams in an increasingly diverse world, including the key characteristics successful managers share. Q: What does it mean to “flex”? Hyun: Flexing is the art of switching between leadership styles to work more effectively with people who are different from you. It’s not fundamentally changing who you are, but it’s understanding when you need to adapt your style in a situation so that you can accommodate people and make them feel more comfortable. It’s understanding the gap that might exist between you and others who are different, and then flexing across that gap to get the result that you're looking for. It’s up to all of us, not just managers, but also employees, to learn how to flex. When you hire new people to the organization, they're expected to adapt. The new people in the organization may need some guidance around how to best flex. They can certainly take the initiative, but if you can give them some direction around the important rules, and connect them with insiders who can help them figure out the most critical elements of the job, that will accelerate how quickly they can contribute to your organization. Q: Why is it important right now for managers to understand flexing? Hyun: The workplace is becoming increasingly younger, multicultural and female. The numbers bear it out. Millennials are entering the workforce and becoming a larger percentage of it, which is a global phenomenon. Thirty-six percent of the workforce is multicultural, and close to half is female. It makes sense to better understand the people who are increasingly a part of your workforce, and how to best lead them and manage them as well. Q: What do companies miss out on when managers don’t flex? Hyun: There are high costs for losing people or failing to engage them. The estimated costs of replacing an employee is about 150 percent of that person’s salary. There are studies showing that employee disengagement costs the U.S. something like $450 billion a year. But voice is the biggest thing you miss out on if you don’t flex. Whenever you want innovation or increased productivity from your people, you need to figure out how to unleash these things. The way you get there is to make sure that everybody’s voice is at the table. Q: What are some of the common misassumptions that managers make about the people on their teams? Hyun: One is what I call the Golden Rule mentality: We assume when we go to the workplace that people are going to think like us and operate like us. But sometimes when you work with people from a different culture or a different generation, they may have a different mindset about doing something, or a different approach to solving a problem, or a different way to manage some situation. When see something that’s different, we don't understand it, so we don't trust it. We have this hidden bias for people who are like us. That gets in the way of really looking at how we can tap our team members best potential by understanding how their difference may help them be effective in our workplace. We’re trained, especially in the workplace, to make assumptions quickly, so that you can make the best business decision. But with people, it’s better to remain curious. If you want to build stronger cross-cultural, cross-generational, cross-gender relationships, before you make a judgment, share what you observe with that team member, and connect with him or her in ways that are mutually adaptive, so that you can work together more effectively. Q: What are the common characteristics you see in leaders who are successful at flexing? Hyun: One is what I call “adaptive ability”—leaders who are able to understand that someone on their team is different from them, and willing to adapt his or her style to do that. Another one is “unconditional positive regard,” which is basically acceptance of others, even in their vulnerable moments. This attitude of grace is critical and essential to a healthy environment in developing people. If you think about when people enter the workforce, they're only 21 years old. It’s quite a formative time for them. They may not have a lot of management experience, or experience managing complex or even global projects. Creating the best possible condition for their development requires turning their mistakes into teachable moments, and giving them an opportunity to really learn. Finally, these leaders are not rigid or constrained in a single mode or style. They have this insatiable curiosity about other people. They don’t judge when they see behavior that doesn’t make sense, or is different from their own. For example, maybe someone on their team is a less aggressive than they are. The leader needs to remain curious and thinks, “Wow, I wonder how I can engage in a dialogue with this person to get their potential out in the open.”

• Silverlight 4 WCF RIA Services and MVVM is not as simple

  - by Thomas Jaskula

  [Disclaimer: I'm ASP.NET MVC Developer] Hi, I'm looking for some best practices with implementing MVVM pattern with WCF RIA in Silverlight 4. I'm not looking to use MEF of IoC for locating my ViewModels. What I would like to know is how to apply MVVM pattern with Silverlight 4 and WCF RIA. I don't want to use other stuff like Prism or MVVM Light toolkit. I found many examples on Internet showing how it is wonderful to drag and drop a datasource on the view and the job is done (it reminds me about my first VB6 developments). I tried to implement MVVM with WCF RIA and it's not strightforward at all. If I understand, the MVVM should contain all the logic in order to unit test it in isolation but when it comes to combine it with WCF RIA it's another story. I have the following questions. Can I use a generated metadata as model ? It would be easier to use it that if I write all from the scratch. As I saw the only way I could get data is through DomainContext or through direct binding in the view (local ressource). I don't want the direct binding in the view, not testable at all. On the other hand I can't use DomainContext, it doesn't expose any single entity !!! All I have is the EntitySet that I can bind to datagrid. How do I bind a single Entity to the DataForm from the ViewModel ? How do I udpate the model to the database ? How do I navigate from one Entity to a collection of it's itemps. For example if I have a Company Entity I would like to show a DataFrom to update a entite informations and a datagrid to show companies adresses. When saving a form would like to save information to Company and for example an information avout which adress was selected as active. Please help me understand how to do it well. Or maybe I should drop the WCF RIA and to do it with WCF from scratch ? What do you think ?

• How to configure Hudson and git plugin with an SSH key

  - by jlpp

  I've got Hudson (continuous integration system) with the git plugin running on a Tomcat Windows Service. msysgit is installed and the msysgit bin dir is in the path. PuTTY/Pageant/plink are installed and msysgit is configured to use them. When I run a job that attempts to clone the git repository I get the following error: $ git clone -o origin git@hostname:project.git "e:\HUDSON_HOME\jobs\Project Trunk\workspace" ERROR: Error cloning remote repo 'origin' : Could not clone git@hostname:project.git ERROR: Cause: Error performing git clone -o origin git@hostname:project.git e:\HUDSON_HOME\jobs\Project Trunk\workspace Trying next repository ERROR: Could not clone from a repository FATAL: Could not clone hudson.plugins.git.GitException: Could not clone Running git clone -o origin git@hostname:project.git "e:\HUDSON_HOME\jobs\Project Trunk\workspace" from the command line works without error. I've confirmed that my issue is not the same as http://stackoverflow.com/questions/1177292/hudson-git-clone-error because git is in the path and I don't get any error about the git executable on Hudson's Configure System page. This leads me to believe that the problem is that the user who owns the Tomcat/Hudson Windows service (Local System) has no SSH key set up to be able to clone the git repository. My question is, how can I set things up so that the git plugin/msysgit know to use a particular SSH key when trying to clone? I don't think Pageant will work because the Tomcat service is running as the "Local System" user, but I may be wrong. I have tried setting Pageant up as a service (using runassvc.exe), passing the appropriate key, and having it run as "Local System". The Tomcat/Hudson service doesn't seem to be able to see the key from the pageant service. Are there any other techniques for setting up a key? Thanks. EDIT: The discussion on http://n4.nabble.com/Hudson-with-git-and-ssh-td375633.html shows that someone else had a similar question. ssh-agent was suggested and this tool does come with msysgit but I'm not sure how to use it in conjunction with the Hudson service. Still, good clue if anyone can fill in the gaps. Thanks to Peter for the comment with the link. Also, the discussion on http://n4.nabble.com/questions-about-git-and-github-plug-ins-td383420.html starts off with the same question. I'm trying to resurrect that thread.

• Uploadify Not Working

  - by azz0r

  Hello, I'll re-edit this to tackle the uploadify issue. Its very strange, essentially the script isn't uploading and isn't triggering onAllComplete. Also if I try to upload an image that's to large, and click Upload files, it skips from 0 to 100%. But does not trigger onAllComplete. It does not upload either. Whats strange, is I have an earlier revision of this and the codes no different and it works, ive tried switched back to the same jquery/uploadify/layout and it still doesnt work. However due to the nature of uploadify not being very forthcoming about errors or whats going on, I can't figure out where its going wrong! Controller: public function manageImagesAction() { $id = $this->_getParam('id'); $object = Eurocreme_Gallery::load_by_fields(array('id' => $id), 1); $images = Eurocreme_Image::load_by_type(array('type' => 'gallery_id', 'values' => $id, 'from' => 0, 'to' => COUNT_HIGH, 'order' => 'gi.position ASC')); $this->view->object = $object; $this->view->images = $images; $this->view->headScript()->appendFile('/library/jquery/uploadify/swfobject.js'); $this->view->headScript()->appendFile('/library/jquery/uploadify/jquery.uploadify.v2.1.0.js'); $this->view->headScript()->appendFile('/library/jquery/ui.js'); } View: <div class="content-area"> <h1>Adding Images To "<?php echo $this->object->name; ?>" Gallery</h1> <p><input id="fileInput2" name="fileInput2" type="file" /></p> <p><a href="javascript:$('#fileInput2').uploadifyUpload();">Upload Files</a> | <a href="javascript:$('#fileInput2').uploadifyClearQueue();">Clear Queue</a></p> </div> <?php if (!empty($this->images)) { ?> <div class="content-area"> <h1>Order Images For <?php echo $this->object->name; ?></h1> <p id="status_update">Drop And Drag Images to re-order them, I will automatically save it for you!</p> <ul id="sort_list"> <?php foreach ($this->images as $image) { ?> <li class="removable" id="recordsArray_<?php echo $image->id; ?>"><img src="/images/Image/thumb/<?php echo $image->image_url; ?>" alt="<?php echo $image->name_url; ?>" title="<?php echo $image->name; ?>" /><p><a class="removable" id="<?php echo $image->id; ?>">Delete</a></p></li> <?php } ?> </ul> <p class="clear"></p> </div> <?php } ?> <?php $this->headScript()->captureStart(); ?> $('document').ready(function() { $("#fileInput2").uploadify({ 'uploader' : '/library/jquery/uploadify/uploadify.swf', 'script' : '/<?php echo $this->object->name_url; ?>/upload.php', 'cancelImg' : '/library/jquery/uploadify/cancel.png', 'folder' : '/images/Image/', 'multi' : true, 'onAllComplete' : function(e, queueId, file, response, data) { window.location.reload(); }, }) //sortable $(function() { $("#sort_list").sortable({ opacity: 0.6, cursor: 'move', update: function() { $("#status_update").html('Processing'); var order = $(this).sortable("serialize"); $.post("/administration/gallery/save-image-order/id/<?php echo $this->object->id; ?>", order, function(theResponse){ $("#status_update").html(theResponse); }); } }); //delete $('a.removable').click(function(){ var id = this.id; $.post("/administration/gallery/delete-image/gallery_id/<?php echo $this->object->id; ?>/image_id/"+id+"", '', function(theResponse) { $("#recordsArray_"+id+"").remove(); }); }); }); }); <?php $this->headScript()->captureEnd(); ?>

• Openvpn plugin openvpn-auth-ldap does not bind to Active Directory

• Android Packaging Problem: resources.ap_ does not exist

  - by Galip

  I am trying to fix a problem in Eclipse for like 3 hours and I haven't made any progress. Tomorrow is the customer coming to look at my app, and I have no time left. This is really frustrating! This morning when I was coding and I wanted to run my app on my device Eclipse crashed all of a sudden. 'aapt.exe has stopped working' After this Eclipse wasn't starting anymore. It froze at the splash image. I looked on the internet and tried different solutions like going back to Java SE 6 update 20, changing .ini file etc. in the end reinstalling Eclipse did the job. Shortly after that the 'aapt.exe has stopped working' returned. I found a solution by changing my projects target. 1.5, 1.6, 2.2 doesn't matter, as long as it's different than the one before. Now I get the Error generating final archive: java.io.FileNotFoundException: C:\xxx\bin\resources.ap_ does not exist error. I tried clean but that doesn't work. Deleting and automatically regenarting R.java also didn't work. I ran the same code in Netbeans with the Android plugin and there it gives me the 'aapt.exe has stopped working' again :( Please guys, how can I fix this? Edit: I think I may have found the reason. These are the error lines in the console: org.xmlpull.v1.XmlPullParserException: Binary XML file line #3: <bitmap> requires a valid src attribute at android.graphics.drawable.BitmapDrawable.inflate(BitmapDrawable.java:341) at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:779) at android.graphics.drawable.Drawable.createFromXml(Drawable.java:720) at com.android.layoutlib.bridge.ResourceHelper.getDrawable(ResourceHelper.java:150) at com.android.layoutlib.bridge.BridgeTypedArray.getDrawable(BridgeTypedArray.java:668) at android.view.View.<init>(View.java:1846) at android.view.View.<init>(View.java:1795) at android.view.ViewGroup.<init>(ViewGroup.java:282) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383) [2011-01-17 16:37:20 - gegevens.xml] Unable to resolve drawable "com.android.layoutlib.utils.ResourceValue@267e33de" in attribute "background" The file it's talking about is 'bg.png'.

• How to avoid open-redirect vulnerability and safely redirect on successful login (HINT: ASP.NET MVC

  - by Brad B.

  Normally, when a site requires that you are logged in before you can access a certain page, you are taken to the login screen and after successfully authenticating yourself, you are redirected back to the originally requested page. This is great for usability - but without careful scrutiny, this feature can easily become an open redirect vulnerability. Sadly, for an example of this vulnerability, look no further than the default LogOn action provided by ASP.NET MVC 2: [HttpPost] public ActionResult LogOn(LogOnModel model, string returnUrl) { if (ModelState.IsValid) { if (MembershipService.ValidateUser(model.UserName, model.Password)) { FormsService.SignIn(model.UserName, model.RememberMe); if (!String.IsNullOrEmpty(returnUrl)) { return Redirect(returnUrl); // open redirect vulnerability HERE } else { return RedirectToAction("Index", "Home"); } } else { ModelState.AddModelError("", "User name or password incorrect..."); } } return View(model); } If a user is successfully authenticated, they are redirected to "returnUrl" (if it was provided via the login form submission). Here is a simple example attack (one of many, actually) that exploits this vulnerability: Attacker, pretending to be victim's bank, sends an email to victim containing a link, like this: http://www.mybank.com/logon?returnUrl=http://www.badsite.com Having been taught to verify the ENTIRE domain name (e.g., google.com = GOOD, google.com.as31x.example.com = BAD), the victim knows the link is OK - there isn't any tricky sub-domain phishing going on. The victim clicks the link, sees their actual familiar banking website and is asked to logon Victim logs on and is subsequently redirected to http://www.badsite.com which is made to look exactly like victim's bank's website, so victim doesn't know he is now on a different site. http://www.badsite.com says something like "We need to update our records - please type in some extremely personal information below: [ssn], [address], [phone number], etc." Victim, still thinking he is on his banking website, falls for the ploy and provides attacker with the information Any ideas on how to maintain this redirect-on-successful-login functionality yet avoid the open-redirect vulnerability? I'm leaning toward the option of splitting the "returnUrl" parameter into controller/action parts and use "RedirectToRouteResult" instead of simply "Redirect". Does this approach open any new vulnerabilities? Side note: I know this open-redirect may not seem to be a big deal compared to the likes of XSS and CSRF, but us developers are the only thing protecting our customers from the bad guys - anything we can do to make the bad guys' job harder is a win in my book. Thanks, Brad

• BizTalk server problem

  - by WtFudgE

  Hi, we have a biztalk server (a virtual one (1!)...) at our company, and an sql server where the data is being kept. Now we have a lot of data traffic. I'm talking about hundred of thousands. So I'm actually not even sure if one server is pretty safe, but our company is not that easy to convince. Now recently we have a lot of problems. Allow me to situate in detail, so I'm not missing anything: Our server has 5 applications: One with 3 orchestrations, 12 send ports, 16 receive locations. One with 4 orchestrations, 32 send ports, 20 receive locations. One with 4 orchestrations, 24 send ports, 20 receive locations. One with 47 (yes 47) orchestrations, 37 send ports, 6 receive locations. One with common application with a couple of resources. Our problems have occured since we deployed the applications with the 47 orchestrations. A lot of these orchestrations use assign shapes which use c# code to do the mapping. This is because we use HL7 extensions and this is kind of special, so by using c# code & xpath it was a lot easier to do the mapping because a lot of these schema's look alike. The c# reads in XmlNodes received through xpath, and returns XmlNode which are then assigned again to biztalk messages. I'm not sure if this could be the cause, but I thought I'd mention it. The send and receive ports have a lot of different types: File, MQSeries, SQL, MLLP, FTP. Each of these types have a different host instances, to balance out the load. Our orchestrations use the BiztalkApplication host. On this server also a couple of scripts are running, mostly ftp upload scripts & also a zipper script, which zips files every half an hour in a daily zip and deletes the zip files after a month. We use this zipscript on our backup files (we backup a lot, backups are also on our server), we did this because the server had problems with sending files to a location where there were a lot (A LOT) of files, so after the files were reduced to zips it went better. Now the problems we are having recently are mainly two major problems: Our most important problem is the following. We kept a receive location with a lot of messages on a queue for testing. After we start this receive location which uses the 47 orchestrations, the running service instances start to sky rock. Ok, this is pretty normal. Let's say about 10000, and then we stop the receive location to see how biztalk handles these 10000 instances. Normally they would go down pretty fast, and it does sometimes, but after a while it starts to "throttle", meaning they just stop being processed and the service instances stay at the same number, for example in 30 seconds it goes down from 10000 to 4000 and then it stays at 4000 and it lowers very very very slowly, like 30 in 5minutes or something. So this means, that all the other service instances of the other applications are also stuck in here, and they are also not processed. We noticed that after restarting our host instances the instance number went down fast again. So we tried to selectively restart different host instances to locate the problem. We noticed that eventually restarting the file send/receive host instance would do the trick. So we thought file sends would be the problem. Concidering that we make a lot of backups. So we replaced the file type backups with mqseries backups. The same problem occured, and funny thing, restarting the file send/receive host still fixes the problem. No errors can be found in the event viewer either. A second problem we're having is. That sometimes at arround 6 am, all or a part of the host instances are being stopped. In the event viewer we noticed the following errors (these are more than one): The receive location "MdnBericht SQL" with URL "SQL://ZNACDBPEG/mdnd0001/" is shutting down. Details:"The error threshold has been exceeded. The receive location is shutting down.". The Messaging Engine failed to add a receive location "M2m Othello Export Start Bestand" with URL "\m2mservices\Othello_import$\DataFilter Start*.xml" to the adapter "FILE". Reason: "The FILE adapter cannot access the folder \m2mservices\Othello_import$\DataFilter Start. Verify this folder exists. Error: Logon failure: unknown user name or bad password. ". The FILE adapter cannot access the folder \m2mservices\Othello_import$\DataFilter Start. Verify this folder exists. Error: Logon failure: unknown user name or bad password. An attempt to connect to "BizTalkMsgBoxDb" SQL Server database on server "ZNACDBBTS" failed. Error: "Login failed for user ''. The user is not associated with a trusted SQL Server connection." It woould seem that there's a login failure at this time and that because of it other services are also experiencing problems, and eventually they are shut down. The thing is, our user is admin, and it's impossible that it's password is wrong "sometimes". We have concidering that the problem could be due to an infrastructure problem, but that's not really are department. I know it's a long post, but we're not sure anymore what to do. Would adding another server and balancing the load solve our problems? Is there a way to meassure our balance and know where to start splitting? What are normal numbers of load etc? I appreciate any answers because these issues are getting worse and we're also on a deadline. Thanks a lot for replies!

• PostgreSQL to Data-Warehouse: Best approach for near-real-time ETL / extraction of data

  - by belvoir

  Background: I have a PostgreSQL (v8.3) database that is heavily optimized for OLTP. I need to extract data from it on a semi real-time basis (some-one is bound to ask what semi real-time means and the answer is as frequently as I reasonably can but I will be pragmatic, as a benchmark lets say we are hoping for every 15min) and feed it into a data-warehouse. How much data? At peak times we are talking approx 80-100k rows per min hitting the OLTP side, off-peak this will drop significantly to 15-20k. The most frequently updated rows are ~64 bytes each but there are various tables etc so the data is quite diverse and can range up to 4000 bytes per row. The OLTP is active 24x5.5. Best Solution? From what I can piece together the most practical solution is as follows: Create a TRIGGER to write all DML activity to a rotating CSV log file Perform whatever transformations are required Use the native DW data pump tool to efficiently pump the transformed CSV into the DW Why this approach? TRIGGERS allow selective tables to be targeted rather than being system wide + output is configurable (i.e. into a CSV) and are relatively easy to write and deploy. SLONY uses similar approach and overhead is acceptable CSV easy and fast to transform Easy to pump CSV into the DW Alternatives considered .... Using native logging (http://www.postgresql.org/docs/8.3/static/runtime-config-logging.html). Problem with this is it looked very verbose relative to what I needed and was a little trickier to parse and transform. However it could be faster as I presume there is less overhead compared to a TRIGGER. Certainly it would make the admin easier as it is system wide but again, I don't need some of the tables (some are used for persistent storage of JMS messages which I do not want to log) Querying the data directly via an ETL tool such as Talend and pumping it into the DW ... problem is the OLTP schema would need tweaked to support this and that has many negative side-effects Using a tweaked/hacked SLONY - SLONY does a good job of logging and migrating changes to a slave so the conceptual framework is there but the proposed solution just seems easier and cleaner Using the WAL Has anyone done this before? Want to share your thoughts?

• how to Use JAXWS/JAXB rename the parameter

  - by shrimpy

  I use CXF(2.2.3) to compile the Amazon Web Service WSDL (http://s3.amazonaws.com/ec2-downloads/2009-07-15.ec2.wsdl) But got error as below. Parameter: snapshotSet already exists for method describeSnapshots but of type com.amazonaws.ec2.doc._2009_07_15.DescribeSnapshotsSetType instead of com.amazonaws.ec2.doc._2009_07_15.DescribeSnapshotsSetResponseType. Use a JAXWS/JAXB binding customization to rename the parameter. The conflict was due to the data type show below: <xs:complexType name="DescribeSnapshotsType"> <xs:sequence> <xs:element name="snapshotSet" type="tns:DescribeSnapshotsSetType"/> </xs:sequence> </xs:complexType> <xs:complexType name="DescribeSnapshotsResponseType"> <xs:sequence> <xs:element name="requestId" type="xs:string"/> <xs:element name="snapshotSet" type="tns:DescribeSnapshotsSetResponseType"/> </xs:sequence> </xs:complexType> I create a binding file try to address the issue...but it didn`t do the job <jaxws:bindings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" wsdlLocation="EC2_2009-07-15.wsdl" xmlns="http://java.sun.com/xml/ns/jaxws" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"> <enableWrapperStyle>false</enableWrapperStyle> <jaxws:bindings node="wsdl:definitions/wsdl:types/xs:schema[@targetNamespace='http://ec2.amazonaws.com/doc/2009-07-15/']"> <jxb:bindings node="xs:complexType[@name='tns:DescribeSnapshotsType']//xs:element[@name='snapshotSet']"> <jxb:property name="snapshotRequestSet"/> </jxb:bindings> <jxb:bindings node="xs:complexType[@name='DescribeSnapshotsResponseType']//xs:element[@name='snapshotSet']"> <jxb:property name="snapshotResponseSet"/> </jxb:bindings> </jaxws:bindings> </jaxws:bindings> And the command i used, was like below <wsdlOptions> <wsdlOption> <wsdl>${basedir}/src/main/resources/wsdl/EC2_2009-07-15.wsdl</wsdl> <extraargs> <extraarg>-b</extraarg> <extraarg>${basedir}/src/main/resources/wsdl/Bindings_EC2_2009-07-15.xml</extraarg> </extraargs> </wsdlOption> </wsdlOptions> What is wrong with my code????

• Reading a POP3 server with only TcpClient and StreamWriter/StreamReader[SOLVED]

  - by WebDevHobo

  I'm trying to read mails from my live.com account, via the POP3 protocol. I've found the the server is pop3.live.com and the port if 995. I'm not planning on using a pre-made library, I'm using NetworkStream and StreamReader/StreamWriter for the job. I need to figure this out. So, any of the answers given here: http://stackoverflow.com/questions/44383/reading-email-using-pop3-in-c are not usefull. It's part of a larger program, but I made a small test to see if it works. Eitherway, i'm not getting anything. Here's the code I'm using, which I think should be correct. EDIT: this code is old, please refer to the second block problem solved. public Program() { string temp = ""; using(TcpClient tc = new TcpClient(new IPEndPoint(IPAddress.Parse("127.0.0.1"),8000))) { tc.Connect("pop3.live.com",995); using(NetworkStream nws = tc.GetStream()) { using(StreamReader sr = new StreamReader(nws)) { using(StreamWriter sw = new StreamWriter(nws)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); while(temp != ".") { temp += sr.ReadLine(); } } } } } Console.WriteLine(temp); } Visual Studio debugger constantly falls over tc.Connect("pop3.live.com",995); Which throws an "A socket operation was attempted to an unreachable network 65.55.172.253:995" error. So, I'm sending from port 8000 on my machine to port 995, the hotmail pop3 port. And I'm getting nothing, and I'm out of ideas. Second block: Problem was apparently that I didn't write the quit command. The Code: public Program() { string str = string.Empty; string strTemp = string.Empty; using(TcpClient tc = new TcpClient()) { tc.Connect("pop3.live.com",995); using(SslStream sl = new SslStream(tc.GetStream())) { sl.AuthenticateAsClient("pop3.live.com"); using(StreamReader sr = new StreamReader(sl)) { using(StreamWriter sw = new StreamWriter(sl)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); sw.WriteLine("QUIT "); sw.Flush(); while((strTemp = sr.ReadLine()) != null) { if(strTemp == "." || strTemp.IndexOf("-ERR") != -1) { break; } str += strTemp; } } } } } Console.WriteLine(str); }
