• Mobile App Notifications in the Enterprise Space: UX Considerations

  - by ultan o'broin

  Here is a really super website of UX patterns for Android: Android Patterns. I was particularly interested in the event-driven notification patterns (aka status bar notifications to developers). Android - unlike iOS (i.e., the iPhone) - offers a superior centralized notifications system for users.   (Figure copyright Android Patterns)   Research in the enterprise applications space shows how users on-the-go, prefer this approach, as: Users can manage their notification alerts centrally, across all media, apps and for device activity, and decide the order in which to deal with them, and when. Notifications, unlike messages in a dialog or information message in the UI, do not block a task flow (and we need to keep task completion to under three minutes). See the Anti-Patterns slideshare presentation on this blocking point too. These notifications must never interrupt a task flow by launching an activity from the background. Instead, the user can launch an activity from the notification. What users do need is the ability to filter this centralized approach, and to personalize the experience of which notifications are added, what the reminder is, ability to turn off, and so on. A related point concerning notifications is when used to provide users with a record of actions then you can lighten up on lengthy confirmation messages that pop up (toasts in the Android world) used when transactions or actions are sent for processing or into a workflow. Pretty much all the confirmation needs to say is the action is successful along with key data such as dollar amount, customer name, or whatever. I am a user of Android (Nexus S), BlackBerry (Curve), and iOS devices (iPhone 3GS and 4). In my opinion, the best notifications user experience for the enterprise user is offered by Android. Blackberry is good, but not as polished and way clunkier than Android’s. What you get on the iPhone, out of the box, is useless in the enterprise.

• The Developers Conference 2012: Presentation about CEP & BAM

  - by Ricardo Ferreira

  This year I had the pleasure again of being one of the speakers in the TDC ("The Developers Conference") event. I have spoken in this event for three years from now. This year, the main theme of the SOA track was EDA ("Event-Driven Architecture") and I decided to delivery a comprehensive presentation about one of my preferred personal subjects: Real-time using Complex Event Processing. The theme of the presentation was "Business Intelligence in Real-time using CEP & BAM" and I would like to share here the presentation that I have done. The material is in Portuguese since was an Brazilian event that happened in São Paulo. Once my presentation has a lot of videos, I decided to share the material as a Youtube video, so you can pause, rewind and play again how many times you want it. I strongly recommend you that before starting watching the video, you change the video quality settings to 1080p in High Definition.

• Auto-hydrate your objects with ADO.NET

  - by Jake Rutherford

  Recently while writing the monotonous code for pulling data out of a DataReader to hydrate some objects in an application I suddenly wondered "is this really necessary?" You've probably asked yourself the same question, and many of you have: - Used a code generator - Used a ORM such as Entity Framework - Wrote the code anyway because you like busy work     In most of the cases I've dealt with when making a call to a stored procedure the column names match up with the properties of the object I am hydrating. Sure that isn't always the case, but most of the time it's 1 to 1 mapping.  Given that fact I whipped up the following method of hydrating my objects without having write all of the code. First I'll show the code, and then explain what it is doing.      /// <summary>     /// Abstract base class for all Shared objects.     /// </summary>     /// <typeparam name="T"></typeparam>     [Serializable, DataContract(Name = "{0}SharedBase")]     public abstract class SharedBase<T> where T : SharedBase<T>     {         private static List<PropertyInfo> cachedProperties;         /// <summary>         /// Hydrates derived class with values from record.         /// </summary>         /// <param name="dataRecord"></param>         /// <param name="instance"></param>         public static void Hydrate(IDataRecord dataRecord, T instance)         {             var instanceType = instance.GetType();                         //Caching properties to avoid repeated calls to GetProperties.             //Noticable performance gains when processing same types repeatedly.             if (cachedProperties == null)             {                 cachedProperties = instanceType.GetProperties().ToList();             }                         foreach (var property in cachedProperties)             {                 if (!dataRecord.ColumnExists(property.Name)) continue;                 var ordinal = dataRecord.GetOrdinal(property.Name);                 var isNullable = property.PropertyType.IsGenericType &&                                  property.PropertyType.GetGenericTypeDefinition() == typeof (Nullable<>);                 var isNull = dataRecord.IsDBNull(ordinal);                 var propertyType = property.PropertyType;                 if (isNullable)                 {                     if (!string.IsNullOrEmpty(propertyType.FullName))                     {                         var nullableType = Type.GetType(propertyType.FullName);                         propertyType = nullableType != null ? nullableType.GetGenericArguments()[0] : propertyType;                     }                 }                 switch (Type.GetTypeCode(propertyType))                 {                     case TypeCode.Int32:                         property.SetValue(instance,                                           (isNullable && isNull) ? (int?) null : dataRecord.GetInt32(ordinal), null);                         break;                     case TypeCode.Double:                         property.SetValue(instance,                                           (isNullable && isNull) ? (double?) null : dataRecord.GetDouble(ordinal),                                           null);                         break;                     case TypeCode.Boolean:                         property.SetValue(instance,                                           (isNullable && isNull) ? (bool?) null : dataRecord.GetBoolean(ordinal),                                           null);                         break;                     case TypeCode.String:                         property.SetValue(instance, (isNullable && isNull) ? null : isNull ? null : dataRecord.GetString(ordinal),                                           null);                         break;                     case TypeCode.Int16:                         property.SetValue(instance,                                           (isNullable && isNull) ? (int?) null : dataRecord.GetInt16(ordinal), null);                         break;                     case TypeCode.DateTime:                         property.SetValue(instance,                                           (isNullable && isNull)                                               ? (DateTime?) null                                               : dataRecord.GetDateTime(ordinal), null);                         break;                 }             }         }     }   Here is a class which utilizes the above: [Serializable] [DataContract] public class foo : SharedBase<foo> {     [DataMember]     public int? ID { get; set; }     [DataMember]     public string Name { get; set; }     [DataMember]     public string Description { get; set; }     [DataMember]     public string Subject { get; set; }     [DataMember]     public string Body { get; set; }            public foo(IDataRecord record)     {         Hydrate(record, this);                }     public foo() {} }   Explanation: - Class foo inherits from SharedBase specifying itself as the type. (NOTE SharedBase is abstract here in the event we want to provide additional methods which could be overridden by the instance class) public class foo : SharedBase<foo> - One of the foo class constructors accepts a data record which then calls the Hydrate method on SharedBase passing in the record and itself. public foo(IDataRecord record) {      Hydrate(record, this); } - Hydrate method on SharedBase will use reflection on the object passed in to determine its properties. At the same time, it will effectively cache these properties to avoid repeated expensive reflection calls public static void Hydrate(IDataRecord dataRecord, T instance) {      var instanceType = instance.GetType();      //Caching properties to avoid repeated calls to GetProperties.      //Noticable performance gains when processing same types repeatedly.      if (cachedProperties == null)      {           cachedProperties = instanceType.GetProperties().ToList();      } . . . - Hydrate method on SharedBase will iterate each property on the object and determine if a column with matching name exists in data record foreach (var property in cachedProperties) {      if (!dataRecord.ColumnExists(property.Name)) continue;      var ordinal = dataRecord.GetOrdinal(property.Name); . . . NOTE: ColumnExists is an extension method I put on IDataRecord which I’ll include at the end of this post. - Hydrate method will determine if the property is nullable and whether the value in the corresponding column of the data record has a null value var isNullable = property.PropertyType.IsGenericType && property.PropertyType.GetGenericTypeDefinition() == typeof (Nullable<>); var isNull = dataRecord.IsDBNull(ordinal); var propertyType = property.PropertyType; . . .  - If Hydrate method determines the property is nullable it will determine the underlying type and set propertyType accordingly - Hydrate method will set the value of the property based upon the propertyType   That’s it!!!   The magic here is in a few places. First, you may have noticed the following: public abstract class SharedBase<T> where T : SharedBase<T> This says that SharedBase can be created with any type and that for each type it will have it’s own instance. This is important because of the static members within SharedBase. We want this behavior because we are caching the properties for each type. If we did not handle things in this way only 1 type could be cached at a time, or, we’d need to create a collection that allows us to cache the properties for each type = not very elegant.   Second, in the constructor for foo you may have noticed this (literally): public foo(IDataRecord record) {      Hydrate(record, this); } I wanted the code for auto-hydrating to be as simple as possible. At first I wasn’t quite sure how I could call Hydrate on SharedBase within an instance of the class and pass in the instance itself. Fortunately simply passing in “this” does the trick. I wasn’t sure it would work until I tried it out, and fortunately it did.   So, to actually use this feature when utilizing ADO.NET you’d do something like the following:        public List<foo> GetFoo(int? fooId)         {             List<foo> fooList;             const string uspName = "usp_GetFoo";             using (var conn = new SqlConnection(_dbConnection))             using (var cmd = new SqlCommand(uspName, conn))             {                 cmd.CommandType = CommandType.StoredProcedure;                 cmd.Parameters.Add(new SqlParameter("@FooID", SqlDbType.Int)                                        {Direction = ParameterDirection.Input, Value = fooId});                 conn.Open();                 using (var dr = cmd.ExecuteReader())                 {                     fooList= (from row in dr.Cast<DbDataRecord>()                                             select                                                 new foo(row)                                            ).ToList();                 }             }             return fooList;         }   Nice! Instead of having line after line manually assigning values from data record to an object you simply create a new instance and pass in the data record. Note that there are certainly instances where columns returned from stored procedure do not always match up with property names. In this scenario you can still use the above method and simply do your manual assignments afterward.

• Data Structure for Small Number of Agents in a Relatively Big 2D World

  - by Seçkin Savasçi

  I'm working on a project where we will implement a kind of world simulation where there is a square 2D world. Agents live on this world and make decisions like moving or replicating themselves based on their neighbor cells(world=grid) and some extra parameters(which are not based on the state of the world). I'm looking for a data structure to implement such a project. My concerns are : I will implement this 3 times: sequential, using OpenMP, using MPI. So if I can use the same structure that will be quite good. The first thing comes up is keeping a 2D array for the world and storing agent references in it. And simulate the world for each time slice by checking every cell in each iteration and further processing if an agents is found in the cell. The downside is what if I have 1000x1000 world and only 5 agents in it. It will be an overkill for both sequential and parallel versions to check each cell and look for possible agents in them. I can use quadtree and store agents in it, but then how can I get the information about neighbor cells then? Please let me know if I should elaborate more.

• SSIS Denali as part of “Enterprise Information Management”

  - by jorg

  When watching the SQL PASS session “What’s Coming Next in SSIS?” of Steve Swartz, the Group Program Manager for the SSIS team, an interesting question came up: Why is SSIS thought of to be BI, when we use it so frequently for other sorts of data problems? The answer of Steve was that he breaks the world of data work into three parts: Process of inputs BI   Enterprise Information Management All the work you have to do when you have a lot of data to make it useful and clean and get it to the right place. This covers master data management, data quality work, data integration and lineage analysis to keep track of where the data came from. All of these are part of Enterprise Information Management. Next, Steve told Microsoft is developing SSIS as part of a large push in all of these areas in the next release of SQL. So SSIS will be, next to a BI tool, part of Enterprise Information Management in the next release of SQL Server. I'm interested in the different ways people use SSIS, I've basically used it for ETL, data migrations and processing inputs. In which ways did you use SSIS?

  - by Richard Lefebvre

  ec4u, a CRM System Integration leader based in Germany and Switzerland, and an historical Oracle/Siebel partner, offers a complete "Siebel2FusionCRM Integration" solution, based on tools methodology and services. ec4u Siebel2FusionCRM Integration solution's main objectives are: Integration between Siebel (on-premise) and Fusion CRM / Marketing (“in the cloud”) Accounts, Contacts and Addresses are maintained by Sales in Siebel CRM and synchronized in real-time into Fusion CRM / Marketing CDM Processing ensures clean data for marketing campaigns (validation and deduplication) Create E-Mail marketing campaigns and newsletters in Fusion The solution features: Upsert processes figure out what information needs to be updated, inserted or terminated (deleted). However, as Siebel is the data master, it is still a one-way synchronization. Handle deleted or nullified information by terminating them in Fusion CRM (set start and end date to define the validity period) Initial load and real-time synchronization use the same processes Invocations/Operations can be repeated due to no transactional support from Fusion web services Tagging sub entries in case of 1 to N mapping (Example: Telephone number is one simple field in Siebel but in Fusion you can have multiple telephone numbers in a sub table) E-Mail-Notification in case of any error (containing error message, instance number, detailed payload) Schematron Validation Interested?

• PHP/MySQL Database application development tool

  - by RCH

  I am an amateur PHP coder, and have built a couple of dozen projects from scratch (including fairly simple e-commerce systems with user authentication, PayPal integration etc - all coded by hand from a clean page. Have also done a price comparison engine that takes data from multiple sites etc.). But I am no expert with OO and other such advanced techniques - I just have a fairly decent grasp of the basics of data processing, logic, functions and trying to optimize code as much as possible. I just want to make this clear so you have some idea of where I'm coming from. I have a couple of fairly large new projects on my plate for corporate clients - both require bespoke database-driven applications with complex relationships, many tables and lots of different front-end functions to manipulate that data for the internal staff in these companies. I figured building these systems from scratch would probably be a huge waste of time. Instead, there must be tools out there that will allow me to construct MySQL databases and build the pages with things like pagination, action buttons, table construction etc. Some kind of database abstraction layer, or system generator, if you will. What tool do you recommend for such a purpose for someone at my level? Open source would be great, but I don't mind paying for something decent as well. Thanks for any advice.

  I accidentally installed Ubuntu to one of my data drives from Windows. The drive was a NTFS drive and contained about 80 GB of important data. The size of the drive is 110 GB. Its new file system is ext4. In an attempt to recover the data, I downloaded foremost and tried the following commands: foremost -i / -o /media/281C8DB01C8D7998/Recovery/ -T -v foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v (sda7 is the drive in question.) It appears that with either command, foremost gets stuck reading some file.

• Metaphor for task synchronization [closed]

  - by nkint

  I'm looking for a metaphor. A friend of mine taught me to use metaphors from nature, everyday life, math, and use them to design my projects. They can help in creating a better design or better understanding or the problem, and they are cool. Now I'm working on a project with hardware and micro-controllers in C. For convenience, I have decided to use multiple micro-controllers as co-processor units for real-time (the slaves) and a master. This has saved me a lot of headache: I can code the main logic in the master without paying too much attention to super optimizing everything; I don't care if I need some blocking-call; I don't worry about serial communication with the computer. I just send messages to the slaves and they are super fast super in real time. I like my design and it seems to work well. So here are the important concepts that I'm trying capture in the metaphor: hierarchy of processing Not using one big brain but rather several small, distributed brain units using distributed power or resources I'm looking for a good metaphor for this concept of having one unit synchronize the work of all the others. Preferably, the metaphor would come from nature, biology, or zoology.

• How will my Electronic Engineering degree be received in the Canadian Game Development market? [closed]

  - by Harikawashi

  I have a Electronic Engineering with Computer Science Degree from a reputable South African university. The EE with CS degree is basically Electronic Engineering, with some of the high voltage subjects thrown out and replaced with computer science subjects - mostly quite theoretical, but not in too much depth. I went on to earn a Masters Degree in Digital Signal Processing, focussing on Speech Recognition in Educational Applications. I have always loved programming - I taught myself QBASIC when I was in primary school, I learned Java at school, did some low level C at University, and taught myself C# and Python while doing my post graduate degree. C# is currently my strong suit, I think I am pretty capable with it. I have two years work experience in Namibia - working as a consulting electrical engineer (no software content whatsoever) and also developing C# desktop applications for the company I work for. I would like to move to Canada next year and work in the Game Development Industry as programmer or software engineer. My interests in particular are towards the more mathematical applications, like game and physics engines, or statistical disciplines like artificial intelligence. However, these are passions - not areas in which I have any work experience. So the question: How well will my BEngEE&CS and MScEng be received in the game industry? Seeing as it's not a pure software degree and I have no official software development work experience?

• Does immutability entirely eliminate the need for locks in multi-processor programming?

  - by GlenPeterson

  Part 1 Clearly Immutability minimizes the need for locks in multi-processor programming, but does it eliminate that need, or are there instances where immutability alone is not enough? It seems to me that you can only defer processing and encapsulate state so long before most programs have to actually DO something. If a program performs actions on multiple processors, something needs to collect and aggregate the results. All this involves multi-process communication before, after, and possibly during some transformations. The start and end state of the machines are different. Can this always be done with no locks just by throwing out each object and creating a new one instead of changing the original (a crude view of immutability)? What cases still require locking? I'm interested in both the theoretical/academic answer and the practical/real-world answer. I know a lot of functional programmers like to talk about "no side effect" but in the "real world" everything has a side effect. Every processor click takes time and electricity and machine resources away from other processes. So I understand that there may be more than one perspective to answer this question from. If immutability is safe, given certain bounds or assumptions, I want to know what the borders of the "safety zone" are exactly. Some examples of possible boundaries: I/O Exceptions/errors Interfaces with programs written in other languages Interfaces with other machines (physical, virtual, or theoretical) Special thanks to @JimmaHoffa for his comment which started this question! Part 2 Multi-processor programming is often used as an optimization technique - to make some code run faster. When is it faster to use locks vs. immutable objects? Given the limits set out in Amdahl's Law, when can you achieve better over-all performance (with or without the garbage collector taken into account) with immutable objects vs. locking mutable ones? Summary I'm combining these two questions into one to try to get at where the bounding box is for Immutability as a solution to threading problems.

• Using the Java SE 8 Date Time API with JPA 2.1

  - by reza_rahman

  Most of you are hopefully aware of the new Date Time API included in Java SE 8. If you are not, you should check them out right now using the Java Tutorial Trail dedicated to the topic. It is a significantly leap forward in processing temporal data in Java. For those who already use Joda-Time the changes will look very familiar - very simplistically speaking the Java SE 8 feature is basically Joda-Time standardized. Quite naturally you will likely want to use the new Date Time APIs in your JPA domain model to better represent temporal data. The problem is that JPA 2.1 will not support the new API out of the box. So what are you to do? Fortunately you can make use of fairly simple JPA 2.1 Type Converters to use the Date Time API in your JPA domain classes. Steven Gertiser shows you how to do it in an extremely well written blog entry. Besides explaining the problem and the solution the entry is actually very good for getting a better understanding of JPA 2.1 Type Converters as well. I think such a set of converters may be a good fit for Apache DeltaSpike as a Java EE 7 extension? In case you are wondering about Java SE 8 support in the JPA specification itself, Nick Williams has already entered an excellent, well researched JIRA entry asking for such support in a future version of the JPA specification that's well worth looking at. Another possibility of course is for JPA providers to start supporting the Date Time API natively before anything is formalized in the specification. What do you think?

After you have insured that the web analytics service configuration is working fine and the Usage Data Import job is importing the *.usage files from the ULS LOGS folder into the WSS_Logging database, and that all the required timer jobs are running as expected… wait for a day for the report to get updated… the report gets updated automatically at 2:00 am in the morning… and i could not find a way to control the schedule for this report update job. So be sure to wait for a day before giving up :)

• Create Pivot collections much faster than DeepZoomTools CollectionCreator class

  - by John Conwell

  I've been playing with Microsoft Live Labs Pivot to create a hierarchy of collections all linked together to allow someone to explore a hierarchy of data visually. The problem has been the generation time of the entire hierarchy. I end up creating 500 - 600 collections total and it takes hours and hours using the CollectionCreator class that comes with the DeepZoomTools.  So digging around I found a way to make the actual DeepZoom collection creation wicked fast. Dont use the CollectionCreator!  Turns out Pivot doesnt actually use the image pyramid generated by the CollectionCreator. Or if it does, its only when you open a new collection it shows all the images zooming in. But once the zoom in is complete, Pivot uses the individual DeepZoom images. What Pivot does need is the xml generated by the CollectionCreator, which is in a very simple format.  So what i did was manually generate the xml for the collection image pyramid, and then create the folder structure required (one folder per level of the pyramid), and put a single pixel png file in each folder.  Now, I can create the required files and folders for 500 collections in about 10 seconds. Sweet! Now you still have to use the ImageCreator to create a DeepZoom image for each image in the collection and that still takes some time, but at least the total processing time is way better.

• New CAM Editor v2.3 with Open-XDX for Open Data APIs

  - by drrwebber

  Creating actual working XML exchanges, loading data from data stores, generating XML, testing, integrating with web services and then deployment delivery takes a lot of coding and effort. Then writing the documentation, models, schema and doing naming and design rule (NDR) checks and packaging all this together (such as for NIEM IEPD use). What if there was a tool that helped you do all that easily and simply? Welcome to the new Open-XDX and the CAM Editor! Open-XDX uses code-free techniques in combination with CAM templates and visual drag and drop to rapidly design your XML exchange. Then Open-XDX will automatically generate all the SQL for you, read the database data, generate and populate the valid output XML, and filter with parameters. To complete the processing solution Open-XDX works with web services and JDBC database connections as a callable module that can be deployed plug and play with your middleware stack, all with just a few lines of Java code (about 5 actually). You can build either Query/Response or Publish/Subscribe services from existing data stores to XML literally in minutes. To see a demonstration of using Open-XDX, a MySQL data store and integrating with Oracle Web Logic server please see this short few minutes video - http://youtube.com/user/TheCameditor There is also a Quick Guide available that provides more technical insights along with a sample pack download of templates and SQL that you can try for yourself. Head on over to our project resource site to learn more, download the latest CAM Editor and see links to all the resources and materials. We look forward to seeing how the developer community is able to jump start information sharing initiatives using this new innovative approach.

• Creating a Website Without a Framework [closed]

  - by James Jeffery

  I've been using PHP Frameworks for so long that I've actually forgot the "best practices" for create websites without one. Usually I will use Symfony, or more recently I've been using Laravel. A client wants a very simple website, but with certain parts of it dynamic. Due to the nature of the site using Wordpress, or a Framework, is out of the question. I'm a sucker for priding myself on my code, but I feel like I'm asking such a basic question that it's killing me to ask. But, what are the best practices for creating websites without a Framework? I like to live by the K.I.S.S (Keep It Simple Stupid!) method of thinking. So, my idea was to just create the .php pages that are required, do any page processing or database interaction on that page, then have the HTML below the closing PHP tag. I would have any helpers/functions in a functions.php file. This is what I remember doing way before I was using Frameworks, and to me it seems like a very old school way of doing things. I've not created a site without a Framework for literally 2+ years, so I've lost my way with the basics. Any advice would be greatly appreciated.

• Non-Obvious Topics to Learn for Game Development

  - by ashes999

  I've been writing games for around 10 years now (from QBasic to C# and everything in-between). I need to start stretching my skills into different areas. What are other, surprising topics I should read up on? Expected topics would include the usual suspects: Programming language of your choice Scripting language Source control Project management (or Agile) Graphics API Maybe some AI (A* path-finding?) Physics (projectile physics) Unit testing (automated testing) I'm looking for more esoteric topics; things that you don't expect to need to know, but if you do know them, they make a difference. This could include things like: Art skills (drawing, lighting, colouring, layout, etc.) Natural language processing The physics of sound (sound-waves, doppler effect, etc.) Personally, I feel that having technical art skills (eg. can make decent art-work if you can only come up with ideas; or, following Photoshop/GIMP tutorials) was the most beneficial for me. This is not intended to be an open-ended question; I'm looking for specific skills that helped you and you expect will continue to benefit you in the short- and long-term.

• Building a linux system

  - by webyankee

  I am worried about hardware compatibility. I have several older PCs with various hardware and wish to install Linux onto them. I have several ideas about what I would like to do. first, I am a novice and know just enough to get me into trouble in a lot of areas. I can not find adequate descriptions of the usage between a desktop and a server version of Linux. When would you want to choose to build a server instead of a desktop and can you change a desktop to a server if you need higher functionality? I wonder if I should use 32 or 64 bit? I believe 32 bit on older (P1 or P2 systems) would be the safe way to go. what is the extent can these systems be used? Can they used to play high end graphics on-line games or just simple browsing and word processing? How do I determine what programs the system can use? I have pondered on the idea of linking several systems together to make one big computer. I know this can be done with some functionality improvement. Any Ideas about this?

• create a .deb Package from scripts or binaries

  - by tdeutsch

  I searched for a simple way to create .deb Packages for things which have no source code to compile (configs, shellscripts, proprietary software). This was quite a problem because most of the package tutorials are assuming you have a source tarball you want to compile. Then I've found this short tutorial (german). Afterwards, I created a small script to create a simple repository. Like this: rm /export/my-repository/repository/* cd /home/tdeutsch/deb-pkg for i in $(ls | grep my); do dpkg -b ./$i /export/my-repository/repository/$i.deb; done cd /export/avanon-repository/repository gpg --armor --export "My Package Signing Key" > PublicKey apt-ftparchive packages ./ | gzip > Packages.gz apt-ftparchive packages ./ > Packages apt-ftparchive release ./ > /tmp/Release.tmp; mv /tmp/Release.tmp Release gpg --output Release.gpg -ba Release I added the key to the apt keyring and included the source like this: deb http://my.default.com/my-repository/ ./ It looks like the repo itself is working well (I ran into some problems, to fix them I needed to add the Packages twice and make the temp-file workaround for the Release file). I also put some downloaded .deb into the repo, it looks like they are also working without problems. But my self created packages didn't... Wenn i do sudo apt-get update, they are causing errors like this: E: Problem parsing dependency Depends E: Error occurred while processing my-printerconf (NewVersion2) E: Problem with MergeList /var/lib/apt/lists/my.default.com_my-repository_._Packages E: The package lists or status file could not be parsed or opened. Has anyone an idea what I did wrong?

• Building a template engine - starting point

  - by Anirudh

  We're building a Django-based project with a template component. This component will be separate from the project as such and can be Django/Python, Node, Java or whatever works. The template has to be rendered into HTML. The templates will contain references to objects with properties that are defined in the DB, say, a Bus. For eg, it could be something like [object type="vehicle" weight="heavy"] and it would have to pull a random object from the DB fulfilling the criteria : type="vehicle" weight="heavy" (bus/truck/jet) and then substitute that tag with an image, say, of a Bus. Also it would have to be able to handle some processing. Eg: What is [X type="integer" lte="10"] + [Y type="integer" lte="10"] [option X+Y correct_ans="true"] [option X-Y correct_ans="false"] [option X+y+1 correct_ans="false"] The engine would be expected to fill in a random integer value <= 10 for X and Y and show radioboxes for each of the options. Would also have to store the fact that the first option is the correct answer. Does it to make sense to write something from the scratch? Or is it better to use an existing templating system (like Django's own templating system) as a starting point? Any suggestions on how I can approach this?
