  • One Year Oracle SocialChat - The Movie

    - by mprove
    Tweet | Like | Watch on Vimeo You’ve just watched – hopefully – my first short movie. Thank you! Here is a bit of the back stage story. About 6 weeks ago colleagues from SNBC (Social Network and Business Collaboration) announced a Social Use Case Competition. It was expected to submit a video of 2 to 5 minutes duration on the Social Enterprise (our internal phrase for Enterprise 2.0). Hmm – I had a few vague ideas, but no script – no actors – no experience in film making. Really the best conditions to try something! I chose our weekly SocialChats as my main topic. But if you don’t do Danish Dogma cinema, you still need a script. Hence I played around with the SocialChat’s archive, and all of a sudden a script and even the actors appeared in front of me. The words that you have just seen are weekly topics. Slightly abridged and rearranged to form a story. Exciting, next phase. How to get it on digital celluloid? I have to confess I am still impressed by epic. (Keep in mind, epic was done in 2004.) And my actors – words – call for a typographic style already. The main part was done over a weekend with Apple Keynote. And I even found a wonderful matching soundtrack among my albums: Didge Goes World by Delago. I picked parts of Second Day and Seventh Day. Literally, the rhythm was set, and I "just" had to complete the movie. Tools used – apart from trial and error: Keynote, Pixelmator, GarageBand, iMovie. Finally I want to mention that I am extremely thankful to BSC Music for granting permissions to use the tracks for this short film! Without this sound it would have been just an ordinary slide show. – Internal note: The next SocialChat is on Death by PowerPoint vs. Presentation Zen. CU this Friday 3pm Greenwich / 7am Pacific.

  • Wrapping REST based Web Service

    - by PaulPerry
    I am designing a system that will be running online under Microsoft Windows Azure. One component is a REST based web service which will really be a wrapper (using proxy pattern) which calls the REST web services of a business partner, which has to do with BLOB storage (note: we are not using azure storage). The majority of the functionality will be taking a request, calling our partner web service, receiving the request and then passing that back to the client. There are a number of reasons for doing this, but one of the big ones is that we are going to support three clients: our desktop application (win and mac), mobile apps (iOS), and a web front end. Having a single API which we then send to our partner protects us if that partner ever changes. I want our service to support both JSON and XML for the data transfer format, JSON for web and probably XML for the desktop and mobile (we already have an XML parser in those products). Our partner also supports both of these formats. I was planning on using ASP.NET MVC 4 with the Web API. As I design this, the thing that concerns me is the static type checking of C#. What if the partner adds or removes elements from the data? We can probably defensively code for that, but I still feel some concern. Also, we have to do a fair amount of tedious coding, to setup our API and then to turn around and call our partner’s API. There probably is not much choice on it though. But, in the back of my mind I wonder if maybe a more dynamic language would be a better choice. I want to reach out and see if anybody has had to do this before, what technology solutions they have used to (I am not attached to this one, these days Azure can host other technologies), and if anybody who has done something like this can point out any issues that came up. Thanks! Researching the issue seems to only find solutions which focus on connecting a SOAP web service over a proxy server, and not what I am referring to here. Note: Cross posted (by suggestion) from http://stackoverflow.com/questions/11906802/wrapping-rest-based-web-service Thank you!

  • The cost of Programmer Team Clustering

    - by MarkPearl
    I recently was involved in a conversation about the productivity of programmers and the seemingly wide range in abilities that different programmers have in this industry. Some of the comments made were reiterated a few days later when I came across a chapter in Code Complete (v2) where it says "In programming specifically, many studies have shown order-of-magnitude differences in the quality of the programs written, the sizes of the programs written, and the productivity of programmers". In line with this is another comment presented by Code Complete when discussing teams - "Good programmers tend to cluster, as do bad programmers". This is something I can personally relate to. I have come across some really good and bad programmers and 99% of the time it turns out the team they work in is the same - really good or really bad. When I have found a mismatch, it hasn't stayed that way for long - the person has moved on, or the team has ejected the individual. Keeping this in mind I would like to comment on the risks an organization faces when forcing teams to remain together regardless of the mix. When you have the situation where someone is not willing to be part of the team but still wants to get a pay check at the end of each month, it presents some interesting challenges and hard decisions to make. First of all, when this occurs you need to give them an opportunity to change - for someone to change, they need to know what the problem is and what is expected. It is unreasonable to expect someone to change but have not indicated what they need to change and the consequences of not changing. If after a reasonable time of an individual being aware of the problem and not making an effort to improve you need to do two things... Follow through with the consequences of not changing. Consider the impact that this behaviour will have on the rest of the team. What is the cost of not following through with the consequences? If there is no follow through, it is often an indication to the individual that they can continue their behaviour. Why should they change if you don't care enough to keep your end of the agreement? In many ways I think it is very similar to the "Broken Windows" principles – if you allow the windows to break and don’t fix them, more will get broken. What is the cost of keeping them on? When keeping a disruptive influence in a team you risk loosing the good in the team. As Code Complete says, good and bad programmers tend to cluster - they have a tendency to keep this balance - if you are not going to help keep the balance they will. The cost of not removing a disruptive influence is that the good in the team will eventually help you maintain the clustering themselves by leaving.

  • Is code like this a "train wreck" (in violation of Law of Demeter)?

    - by Michael Kjörling
    Browsing through some code I've written, I came across the following construct which got me thinking. At a first glance, it seems clean enough. Yes, in the actual code the getLocation() method has a slightly more specific name which better describes exactly which location it gets. service.setLocation(this.configuration.getLocation().toString()); In this case, service is an instance variable of a known type, declared within the method. this.configuration comes from being passed in to the class constructor, and is an instance of a class implementing a specific interface (which mandates a public getLocation() method). Hence, the return type of the expression this.configuration.getLocation() is known; specifically in this case, it is a java.net.URL, whereas service.setLocation() wants a String. Since the two types String and URL are not directly compatible, some sort of conversion is required to fit the square peg in the round hole. However, according to the Law of Demeter as cited in Clean Code, a method f in class C should only call methods on C, objects created by or passed as arguments to f, and objects held in instance variables of C. Anything beyond that (the final toString() in my particular case above, unless you consider a temporary object created as a result of the method invocation itself, in which case the whole Law seems to be moot) is disallowed. Is there a valid reasoning why a call like the above, given the constraints listed, should be discouraged or even disallowed? Or am I just being overly nitpicky? If I were to implement a method URLToString() which simply calls toString() on a URL object (such as that returned by getLocation()) passed to it as a parameter, and returns the result, I could wrap the getLocation() call in it to achieve exactly the same result; effectively, I would just move the conversion one step outward. Would that somehow make it acceptable? (It seems to me, intuitively, that it should not make any difference either way, since all that does is move things around a little. However, going by the letter of the Law of Demeter as cited, it would be acceptable, since I would then be operating directly on a parameter to a function.) Would it make any difference if this was about something slightly more exotic than calling toString() on a standard type? When answering, do keep in mind that altering the behavior or API of the type that the service variable is of is not practical. Also, for the sake of argument, let's say that altering the return type of getLocation() is also impractical.

  • EBS Accounts Payables Customer Advisory

    - by cwarticki
    Blogging to let you know of an important set of Oracle Payables patches that were released for R12.1 customers.  Accounts Payable Customer Advisory: Dear Valued Oracle Support Customer, Since the release of R12.1.3 a number of recommended Payables patches have been made available as standalone patches, to help address important business process incidents. Adoption of these patches is highly recommended. To further facilitate adoption of these Payables patches Oracle has consolidated them into a single Recommended Patch Collection (RPC). The RPC is a collection of recommended Payables patches created with the following goals in mind: Stability: Help address issues that are identified by Oracle Development and Oracle Software Support that may interfere with the normal completion of important business processes such as period close. Root Cause Fixes: Help make available root cause fix for data integrity that may delay period close, normal invoice flow and other business actions. Compact: Keep the file footprint as small as possible to help facilitate the install process and minimize testing. Granular: Collection of patches based on functional area that allows customer to apply, based on their individual needs and goals, all three RPC’s at once or in phases. Payables: -          New AP RPC (14273383:R12.AP.B) has all data corruption root cause fixes known to date plus tons of other crucial fixes (Note: 1397581.1). -          Companion must have RPCs: o   Note: 1481221.1: R12.1: Payments Recommended Patch Collection (IBY RPC), August 2012 o   Note: 1481235.1: R12.1: E-Business Tax Recommended Patch Collection (ZX RPC), August 2012 o   Note: 1481222.1: R12.1: Sub Ledger Accounting (SLA) Recommended Patch Collection (XLA RPC), August 2012 -          This time we beat the system far harder on testing and it held up remarkably well. We could not get any data corruption events in the Invoice Cancel/Discard flow (that is the #1 generator) neither we could cause Orphan Events in the system. Therefore this is very good code. Financials: -          ALL FIN modules now have RPCs: full listing is in (Note: 954704.1)

  • Focusing on Mobile @ Oracle OpenWorld

    - by Carlos Chang
    Plenty of exciting trends in the industry today: Cloud, Big Data, Mobile, etc. The first two are amazing of course, but for me, it's mobile, mobile and... MOBILE.   Why? Think back to the mozilla browser (Marc Andreessen's mozilla, not today's mozilla.org), Netscape and the nascent beginnings of the World Wide Web. Amazing times. Companies were just starting to set up their home pages, basic HTML, hyperlinks, images, ooooh, aaaah.  Yahoo! was *the* search engine back then. :-\   Anywhoo, I would pose that mobile today, we are in a similar junction. Sure, there's millions of apps on Apple's App Store and Google Play, but within the enterprise, it's just getting started. I'm talking about going beyond the simple, tactical apps such as calendaring, contacts or directory service lookup. And while mobile first a common mantra, I'm referring to mobile plus which includes and looks upon the whole enterprise holistically and adds new parameters, such as your GPS location, perhaps even your vital signs. (Apple's health kit?)  Everything is going mobile. Everything connected. But with the enterprise - scalability, security, integration, app management, user management, etc. Amazing times ahead. Ok, got that off my mind. Oracle OpenWorld 2014 - Going Mobile!  If you're coming to the big dance, I've highlighted some key mobile sessions below. And if you see me around, and there's a bar within reach, high five me for a beer. I mean, if you read this far, and didn't already jump to the list below, I think you deserve one.   Cheers!  Monday, 9/29/14 at 10:15 AM - General Session: Time for You to Rethink Mobile?

  • What is the best way to implement collision detection using Bullet physics engine and a track generated from a curve?

    - by tigrou
    I am developing a small racing game were the track is generated from a curve. As said above, the track is generated, but not infinite. The track of one level could fit with no problem in memory and will contain a reasonably small amount of triangles. For collisions, I would like to use Bullet physics engine and know what is the best way to handle collisions with the track efficiently. NOTE : The track will be stored as a static rigid body (mass = 0). The player will be represented by a sphere shape for collisions. Here is some possibilities i have in mind : Create one rigid body, then, put all triangles of the track (except non collidable stuff) into it. Result : 1 body with many triangles (eg : 30000 triangles) Split the track into several sections (eg: 10 sections). Then, for each section, create a rigid body and put corresponding triangles in it. Result : small amount of bodies with relatively small amount of triangles (eg : 1500 triangles per section). Split the track into many sub-sections (eg : 1200 sections). Here one subsection = very small step when generating the curve. Again for each sub-section, create a body and put triangles in it. Result : many bodies with very small amount of triangles (eg : 20 triangles). Advantage : it could be possible to "extra data" to each of the subsection, that could be used when handling collisions. Same as 2, but only put sections N and N+1 in physics engine (where N = current section where the player is). When player reach section N+1, unload section N and load section N+2 and so on... Issue : harder to implement, problems if the player suddenly "jump" from one section to another (eg : player fly away from section N, and fall on section N + 4 that was underneath : no collision handled, player will fall into void ) Same as 4, but with many sub-sections. Issues : since subsections are very small there will be constantly new bodies added and removed to physics engine at runtime. Possibilities for player to accidently skip some sections and fall into the void are higher than 4.

  • Move Data into the Grid for Scalable, Predictable Response Times

    - by JuergenKress
    CloudTran is pleased to introduce the availability of the CloudTran Transaction and Persistence Manager for creating scalable, reliable data services on the Oracle Coherence In-Memory Data Grid (IMDG). Use of IMDG architectures has been key to handling today’s web-scale loads because it eliminates database latency by storing important and frequently access data in memory instead of on disk. The CloudTran product lets developers easily use an IMDG for full ACID-compliant transactions without having to be concerned about the location or spread of data. The system has its own implementation of fast, scalable distributed transactions that does NOT depend on XA protocols but still guarantees all ACID properties. Plus, CloudTran asynchronously replicates data going into the IMDG to back-end datastores and back-up data centers, again ensuring ACID properties. CloudTran can be accessed through Java Persistence API (JPA via TopLink Grid) and now, through a new Low-Level API, or LLAPI. This is ideal for use in SOA applications that need data reliability, high availability, performance, and scalability. Still in limited beta release, the LLAPI gives developers the ability to use standard put/remove logic available in Coherence and then wrap logic with simple Spring annotations or XML+AspectJ to start transactions. An important feature of LLAPI is the ability to join transactions. This is a common outcome for SOA applications that need to reduce network traffic by aggregating data into single cache entries and then doing SOA service processing in the node holding the data. This results in the need to orchestrate transaction processing across multiple service calls. CloudTran has the capability to handle these “multi-client” transactions at speed with no loss in ACID properties. Developing software around an IMDG like Oracle Coherence is an important choice for today’s web-scale applications and services. But this introduces new architectural considerations to maintain scalability in light of increased network loads and data movement. Without using CloudTran, developers are faced with an incredibly difficult task to ensure data reliability, availability, performance, and scalability when working with an IMDG. Working with highly distributed data that is entirely volatile while stored in memory presents numerous edge cases where failures can result in data loss. The CloudTran product takes care of all of this, leaving developers with the confidence and peace of mind that all data is processed correctly. For those interested in evaluating the CloudTran product and IMDGs, take a look at this link for more information: http://www.CloudTran.com/downloadAPI.php, or, send your questions to [email protected].

  • Using the @ in SQL Azure Connections

    - by BuckWoody
    The other day I was working with a client on an application they were changing to a hybrid architecture – some data on-premise and other data in SQL Azure and Windows Azure Blob storage. I had them make a couple of corrections - the first was that all communications to SQL Azure need to be encrypted. It’s a simple addition to the connection string, depending on the library you use. Which brought up another interesting point. They had been using something that looked like this, using the .NET provider: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=LoginName;Password=myPassword; Trusted_Connection=False;Encrypt=True; This includes most of the formatting needed for SQL Azure. It specifies TCP as the transport mechanism, the database name is included, Trusted_Connection is off, and encryption is on. But it needed one more change: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=[LoginName]@[serverName];Password=myPassword; Trusted_Connection=False;Encrypt=True; Notice the difference? It’s the User ID parameter. It includes the @ symbol and the name of the server – not the whole DNS name, just the server name itself. The developers were a bit surprised, since it had been working with the first format that just used the user name. Why did both work, and why is one better than the other? It has to do with the connection library you use. For most libraries, the user name is enough. But for some libraries (subject to change so I don’t list them here) the server name parameter isn’t sent in the way the load balancer understands, so you need to include the server name right in the login, so the system can parse it correctly. Keep in mind, the string limit for that is 128 characters – so take the @ symbol and the server name into consideration for user names. The user connection info is detailed here: http://msdn.microsoft.com/en-us/library/ee336268.aspx Upshot? Include the @servername on your connection string just to be safe. And plan for that extra space…

  • 5 ways to stop code thrashing&hellip;

    - by MarkPearl
    A few days ago I was programming on a personal project and hit a roadblock. I was applying the MVVM pattern and for some reason my view model was not updating the view when the state changed??? I had applied this pattern many times before and had never had this problem. It just didn’t make sense. So what did I do… I did what anyone would have done in my situation and looked to pass the blame to someone or something else. I tried to blame one of the inherited base classes, but it looked fine, then to Visual Studio, but it seemed to be fine and eventually to any random segment of code I came across. My elementary problem had now mushroomed into one that had lost any logical basis and I was in thrashing mode! So what to do when you begin to thrash? 1) Do a general code cleanup – Now there is a difference between cleaning code and changing code . When you thrash you change code and you want to avoid this. What you really want to do is things like rename variables to have better meaning and go over your comments. 2) Do a proof of concept – if cleaning code doesn’t help. The  you want to isolate the problem and identify the key concepts. When you isolate code you ideally want it to be in a totally separate project with as little complexity as possible. Make the building blocks and try and replicate the functionality that you are getting in your current application. 3) Phone a friend – I have found speaking to someone else about the problem generally helps me solve any thrashing issues I am having. Usually they don’t even have to say anything to solve the problem, just you talking them through the problem helps you get clarity of mind. 4) Let the dust settle – Sometimes time is the best solution. I have had a few problems that no matter who I discussed them with and no matter how much code cleaning I had done I just couldn’t seem to fix it. My brain just seemed to be going in circles. A good nights rest has always helped and often just the break away from the problem has helped me find a solution. 5) Stack overflow it – So similar to phone a friend. I am really surprised to see what a melting pot stack overflow has been and what a help it has been in solving technology specific problems. Just be considerate to those using the site and explain clearly exactly what problem you are having and the technologies you are using or else you will probably not get any useful help…

  • Expanding Influence and Community

    - by Johnm
    When I was just nine years of age my father introduced me to the computer. It was a Radio Shack TRS-80 Color Computer (aka: CoCo). He shared with me the nuances of writing BASIC and it wasn't long before I was in the back seat of the school bus scribbling, on a pad of paper, the code I would later type. My father demonstrated that while my friends were playing their Atari 2600 consoles, I had the unique opportunity to create my own games on the Coco. One of which provided a great friend of mine hours and hours of hilarity and entertainment. It wasn't long before my father was inviting me to tag along as he drove to the local high school where a gathering of fellow Coco enthusiasts assembled. In these meetings all in attendance would chat about their latest challenges and solutions. They would swap the labors of their sleepless nights eagerly gazing into their green and black screens. Friendships were built and business partners were developed. While these experiences at the time in my pre-teen mind were chalked up to simply sharing time with my father, it had a tremendous impact on me later in life. This past weekend I attended the Louisville SQL Saturday (#45). It was great to see that there were some who brought along their children. It is encouraging to see fresh faces in the crowd at our  monthly IndyPASS meetings. Each time I see the youthful eyes peering from the audience while the finer details of SQL Server is presented, I cannot help but to be transported back to the experiences that I enjoyed in those Coco days. It is exciting to think of how these experiences are impacting their lives and stimulating their minds. Some of these children have actually approached me asking questions about what was presented or simply bragging about their latest discovery in programming. One of the topics that arose in the "Women in Technology" session in Louisville, which was masterfully facilitated by Kathi Kellenberger, was exploring how we could ignite the spark of interest in databases among the youth. It was awesome to hear that there were some that volunteer their time to share their experiences with students. It made me wonder what user groups could achieve if we were to consider expanding our influence and community beyond our immediate peers to include those who are simply enjoying their time with their father or mother.

  • Help identify the pattern for reacting on updates

    - by Mike
    There's an entity that gets updated from external sources. Update events are at random intervals. And the entity has to be processed once updated. Multiple updates may be multiplexed. In other words there's a need for the most current state of entity to be processed. There's a point of no-return during processing where the current state (and the state is consistent i.e. no partial update is made) of entity is saved somewhere else and processing goes on independently of any arriving updates. Every consequent set of updates has to trigger processing i.e. system should not forget about updates. And for each entity there should be no more than one running processing (before the point of no-return) i.e. the entity state should not be processed more than once. So what I'm looking for is a pattern to cancel current processing before the point of no return or abandon processing results if an update arrives. The main challenge is to minimize race conditions and maintain integrity. The entity sits mainly in database with some files on disk. And the system is in .NET with web-services and message queues. What comes to my mind is a database queue-like table. An arriving update inserts row in that table and the processing is launched. The processing gathers necessary data before the point of no-return and once it reaches this barrier it looks into the queue table and checks whether there're more recent updates for the entity. If there are new updates the processing simply shuts down and its data is discarded. Otherwise the processing data is persisted and it goes beyond the point of no-return. Though it looks like a solution to me it is not quite elegant and I believe this scenario may be supported by some sort of middleware. If I would use message queues for this then there's a need to access the queue API in the point of no-return to check for the existence of new messages. And this approach also lacks elegance. Is there a name for this pattern and an existing solution?

  • Quickly Copy Movie Files to Individually Named Folders

    - by DigitalGeekery
    Some HTPC media manager applications require movie files to be in stored in separate folders to properly store information such as cover art images and other metadata. Here we look at copying movie files to individual folders. If you already have a large movie collection stored in a single folder, we’ll show you how to quickly move those files into their own individually named folders. File2Folder FIle2folder is a handy portable app that automatically creates and moves movie files into a folder of the same filename. There is no installation needed. Simply download and run the .exe file (link below). Enter the current movie directory, or browse for the folder. File2folder now supports both local and network shares. When you are ready to create the folders and move the files, click Move! You’ll see the move progress displayed in the window. When the process is finished, you’ll have all your movie file in individual folders.   Change your mind? Just click the Undo! button…   …and the move and folder creation process will be undone. If you would like to have the folder monitored for new files, click the Start button. File2folder will process any new files it discovers every 180 seconds. To turn it off, click Stop. This simple little program is a huge timesaver for those looking to organize movie collections for their HTPC. We should also note that this will work with any files, not just videos.

  • Setting MTU on Exalogic

    - by csoto
    For many reasons, a system administrator may want to change the MTU settings of a server. But in a system like Exalogic which contains lots of interconnected nodes and other various components, it's important to understand how this applies to the different networks. For example, when bringing up bonding of InfiniBand an error like the following may be thrown: Bringing up interface bond1: SIOCSIFMTU: Invalid argument Both scripts ifcfg-ib0 and ifcfg-ib1 (from the /etc/sysconfig/network-scripts/ direectory) have MTU set to 65500, which is a valid MTU value only if all IPoIB slaves operate in connected mode and are configured with the same value, so the line below must be added to both network scripts and then restart the network: CONNECTED_MODE=yes By the way, an error of the form “SIOCSIFMTU: Invalid argument” indicates that the requested MTU was rejected by the kernel. Typically this would be due to it exceeding the maximum value supported by the interface hardware. In that case you must either reduce the MTU to a value that is supported or obtain more capable hardware. This problem has been seen when trying to modify the MTU using the ifconfig command, like the output of the example below: [root@elxxcnxx ~]# ifconfig ib1 mtu 65520 SIOCSIFMTU: Invalid argument It's important to insist that in most cases the nodes must be rebooted after the MTU size has been changed. Although in some circumstances it may work without a reboot, it is not how it is typically documented. Now, in order to achieve a reduced memory consumption and improve performance for network traffic received on IPoIB related interfaces, it is recommend to reduce the MTU value in interface configuration files for IPoIB related bonds from 65520 to 64000. The change needs to be made to interface configuration files under the /etc/sysconfig/network-scripts directory and applies to the interface configuration files for bonds over IPoIB related slave devices, for example /etc/sysconfig/network-scripts/ifcfg-bond1. However, keep in mind that the numeric portion of the interface filenames that corresponding to IPoIB interfaces is expected to vary across compute nodes and vServers and so cannot be relied upon to identify which interface files are for bonds are over IPoIB rather than EoIB related slave interfaces. To fix these MTU values to the recommended settings, there are very useful instructions and a script on the MOS Note 1624434.1, and it's applicable physical and virtual configurations of Exalogic. Regarding the recommended MTU value for EoIB related interfaces, its maximum appropriate value is 1500. If for some reason a vServer has been created with a higher value (set on the /etc/sysconfig/network-scripts/ifcfg-bond0 file), then it must be fixed. An error like the following could be thrown under this circumstance: [root@vServer ~]# service network restart ... Bringing up interface bond0:  SIOCSIFMTU: Invalid argument Also an error like the one below can be seen on the /var/log/messages file of the vServer: kernel: T5074835532 [mlx4_vnic] eth1:vnic_change_mtu:360: failed: new_mtu 64000 2026 The MOS Note 1611657.1 is very useful for this purpose.

  • Block-level deduplicating filesystem

    - by James Haigh
    I'm looking for a deduplicating copy-on-write filesystem solution for general user data such as /home and backups of it. It should use online/inline/synchronous deduplication at the block-level using secure hashing (for negligible chance of collisions) such as SHA256 or TTH. Duplicate blocks need not even touch the disk. The idea is that I should be able to just copy /home/<user> to an external HDD with the same such filesystem to do a backup. Simple. No messing around with incremental backups where corruption to any of the snapshots will nearly always break all later snapshots, and no need to use a specific tool to delete or 'checkout' a snapshot. Everything should simply be done from the file browser without worry. Can you imagine how easy this would be? I'd never have to think twice about backing-up again! I don't mind a performance hit, reliability is the main concern. Although, with specific implementations of cp, mv and scp, and a file browser plugin, these operations would be very fast, especially when there is a lot of duplication as they would only need to transfer the absent blocks. Accidentally using conventional copy tools that do not integrate with the FS would merely take longer, waste some bandwidth when copying remotely and waste some CPU, as the duplicate data would be re-read, re-transferred and re-hashed (although nothing would be re-written), but would absolutely not corrupt anything. (Some filesharing software may also be able to benefit by integrating with the FS.) So what's the best way of doing this? I've looked at some options: lessfs - Looks unmaintained. Any good? [Opendedup/SDFS][3] - Java? Could I use this on Android?! What does [SDFS][4] stand for? [Btrfs][5] - Some patches floating around on mailing list archives, but no real support. [ZFS][6] - Hopefully they'll one day relicense under a true Free/Opensource GPL-compatible licence. Also, 2 years ago I had a go at an attempt in Python using Fuse at the file-level to be used over the top of a typical solid FS such as EXT4, but I found Fuse for Python underdocumented and didn't manage to implement all of the system calls. My first post here, so I can't post more than 2 links until I get over 10 rep: [3]: http://www.opendedup.org/ [4]: https://en.wikipedia.org/w/index.php?title=SDFS&action=edit&redlink=1 [5]: https://en.wikipedia.org/wiki/Btrfs#Features [6]: https://en.wikipedia.org/wiki/ZFS#Linux

  • How to apply effects that occur (or change) over time to characters in a game?

    - by Joshua Harris
    So assume that I have a system that applies Effects to Characters like so: public class Character { private Collection<Effect> _effects; public void AddEffect (Effect e) { e.ApplyTo(this); _effects.Add(e); } public void RemoveEffect (Effect e) { e.RemoveFrom(this); _effects.Remove(e); } } public interface Effect { public void ApplyTo (Character character); public void RemoveFrom (Character character); } Example Effect: Armor Buff for 5 seconds. void someFunction() { // Do Stuff ... Timer armorTimer = new Timer(5 seconds); ArmorBuff armorbuff = new ArmorBuff(); character.AddEffect(armorBuff); armorTimer.Start(); // Do more stuff ... } // Some where else in code public void ArmorTimer_Complete() { character.RemoveEffect(armorBuff); } public class ArmorBuff implements Effect { public void applyTo(Character character) { character.changeArmor(20); } public void removeFrom(Character character) { character.changeArmor(-20); } } Ok, so this example would buff the Characters armor for 5 seconds. Easy to get working. But what about effects that change over the duration of the effect being applied. Two examples come to mind: Damage Over Time: 200 damage every second for 3 seconds. I could mimic this by applying an Effect that lasts for 1 second and has a counter set to 3, then when it is removed it could deal 200 damage, clone itself, decrement the counter of the clone, and apply the clone to the character. If it repeats this until the counter is 0, then you got a damage over time ability. I'm not a huge fan of this approach, but it does describe the behavior exactly. Degenerating Speed Boost: Gain a speed boost that degrades over 3 seconds until you return to your normal speed. This is a bit harder. I can basically do the same thing as above except having timers set to some portion of a second, such that they occur fast enough to give the appearance of degenerating smoothly over time (even though they are really just stepping down incrementally). I feel like you could get away with only 12 steps over a second (maybe less, I would have to test it and see), but this doesn't seem very elegant to me. The only other way to implement this effect would be to change the system so that the Character checks the _effects collection for effects that alter any of the properties any time that they are being used. I could handle this in functions like getCurrentSpeed() and getCurrentArmor(), but you can imagine how much of a hassle it would be to have that kind of overhead every time you want to do a calculation with movement speed (which would be every time you move your character). Is there a better way to deal with these kinds of effects or events?

  • How do I know if I am using Scrum methodologies?

    - by Jake
    When I first started at my current job, my purpose was to rewrite a massive excel-VBA workbook-application to C# Winforms because it was thought that the new C# app will fix all existing problems and have all the new features for a perfect world. If it were a direct port, in theory it would be easy as i just need to go through all the formulas, conditional formatting, validations, VBA etc. to understand it. However, that was not the case. Many of the new features are tightly dependant on business logic which I am unfamiliar with. As a solo programmer, the first year was spent solely on deciphering the excel workbook and writing the C# app. In theory, I had the business people to "help" me specify requirements, how GUI looks and work, and testing of the app etc; but in practice it is like a contant tsunami of feature creep. At the beginning of the second year I managed to convince the management that this is not going anywhere. I made them start from scratch with the excel-VBA. I have this "issue log" saved on the network, each time they found something they didn't like about the excel-VBA app, they will write it in there. I check the log daily and consolidate issues (in my mind) mainly into 2 groups: (1) requires massive change. (2) can be fixed in current version. For massive change issues, I make a copy of the latest excel-VBA and give it a new version number, then work on it whenever I can. For current version fixes, I make the changes in a few days to a week, and then immediately release it. I also ensure I update the same change in any in-progress massive change future versions. This has gone on for about 4 months and I feel it works great. I made many releases and solved many real issues, also understood the business logic more and more. However, my boss (non-IT trained) thinks what I am doing are just adhoc changes and that i am not looking at the "bigger picture". I am struggling to convince my boss that this works. So I hope to formalise my approach and maybe borrow a buzzword to confuse him. Incidentally, I read about Agile and SCRUM, about backlog and sprints. But it's all very vague to me still. QUESTION (finally): I want to tell him that this is SCRUM! But I want to hold my breath first and ask whether my current approach is considered SCRUM or SCRUM-like? How can I make it more SCRUM-like? Note that I have only myself, there's no project leader or teams.

  • Multiplayer tile based movement synchronization

    - by Mars
    I have to synchronize the movement of multiple players over the Internet, and I'm trying to figure out the safest way to do that. The game is tile based, you can only move in 4 directions, and every move moves the sprite 32px (over time of course). Now, if I would simply send this move action to the server, which would broadcast it to all players, while the walk key is kept being pressed down, to keep walking, I have to take this next command, send it to the server, and to all clients, in time, or the movement won't be smooth anymore. I saw this in other games, and it can get ugly pretty quick, even without lag. So I'm wondering if this is even a viable option. This seems like a very good method for single player though, since it's easy, straight forward (, just take the next movement action in time and add it to a list), and you can easily add mouse movement (clicking on some tile), to add a path to a queue, that's walked along. The other thing that came to my mind was sending the information that someone started moving in some direction, and again once he stopped or changed the direction, together with the position, so that the sprite will appear at the correct position, or rather so that the position can be fixed if it's wrong. This should (hopefully) only make problems if someone really is lagging, in which case it's to be expected. For this to work out I'd need some kind of queue though, where incoming direction changes and stuff are saved, so the sprite knows where to go, after the current movement to the next tile is finished. This could actually work, but kinda sounds overcomplicated. Although it might be the only way to do this, without risk of stuttering. If a stop or direction change is received on the client side it's saved in a queue and the char keeps moving to the specified coordinates, before stopping or changing direction. If the new command comes in too late there'll be stuttering as well of course... I'm having a hard time deciding for a method, and I couldn't really find any examples for this yet. My main problem is keeping the tile movement smooth, which is why other topics regarding synchronization of pixel based movement aren't helping too much. What is the "standard" way to do this?

  • How to set the initial component focus

    - by frank.nimphius
    Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} In ADF Faces, you use the af:document tag's initialFocusId to define the initial component focus. For this, specify the id property value of the component that you want to put the initial focus on. Identifiers are relative to the component, and must account for NamingContainers. You can use a single colon to start the search from the root, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container and begin the search from there, ":::" will pop out of two naming containers and begin the search from there. Alternatively you can add the naming container IDs as a prefix to the component Id, e.g. nc1:nc2:comp1. http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e12419/tagdoc/af_document.html To set the initial focus to a component located in a page fragment that is exposed through an ADF region, keep in mind that ADF Faces regions - af:region - is a naming container too. To address an input text field with the id "it1" in an ADF region exposed by an af:region tag with the id r1, you use the following reference in af:document: <af:document id="d1" initialFocusId="r1:0:it1"> Note the "0" index in the client Id. Also, make sure the input text component has its clientComponent property set to true as otherwise no client component exist to put focus on.

  • Documenting sp_ssiscatalog

    - by jamiet
    What is the best way to document an API? Moreover, what is the best way to document a T-SQL API? Before I try to answer those questions I should explain what I mean by “a T-SQL API”. I think of an API as being a collection of well-defined, known, code modules that provide some notion of a service to whomever uses it; in T-SQL terms I tend to think of a collection of stored procedures and functions as a form of API. Its a loose definition, I admit, and in SQL Server circles we don’t tend to think of stored procedures collectively as an API but if you think about it that’s exactly what they are. The question of how to document a T-SQL API came to my mind as I worked on sp_ssiscatalog. How could I make it easy for people to learn about the capabilities of sp_ssiscatalog without forcing them to dig through the code and find out for themselves? My opening gambit was to write documentation pages on the wiki at http://ssisreportingpack.codeplex.com. That’s kinda useful but it does suffer the disadvantage that someone using sp_ssiscatalog needs to go visit a webpage to read it – I want the documentation to be available wherever the user is using sp_ssiscatalog. Moreover, maintaining the wiki is a real PITA. Intellisense works up to a point, I guess: but that only shows whatever SQL Server knows about the various parameters, which isn’t all that much! I wanted a better way for my API users to learn about its capabilities and so I hit upon the idea of simply using PRINT statements within the code itself to inform the user what options are available; hence I added such PRINT statements in the latest check-in. Now when you execute (for example): EXEC sp_ssiscatalog @operation_type='execs' you can hit F6 a few times to view the messages pane and you shall see something like this: Notice that I’m returning information about all the parameters that can be used to affect the results that just got returned. I really do think this will be very useful to anyone using sp_ssiscatalog; I myself am always forgetting what the parameters are and I wrote the damn thing so I can’t really expect anyone else to remember them. I have not yet made available a release that has these changes in it but when I do I’ll blog about it right here. At the time of writing the latest available release of sp_ssiscatalog is DB v1.0.1.0 but if you want to the latest and greatest simply download it straight from source. Feedback is welcome as always. @Jamiet

  • How should I land my next consulting gig? [closed]

    - by MrOodles
    For the last couple of years, I've been working on speculative projects, expanding my skillset with side work, and paying the bills while having a blast consulting for startups. However, for a number of personal reasons, I need to spend the next 6-9 months maximizing my cash income. I want to put this into effect starting in early August. So that means I have one month to put the necessary client list/portfolio/resume together to start making this happen. As a programmer, I am very proficient in building Django web apps. I can write the necessary SQL, python, javascript, and css to build every part of a Django app, and then do the system administration necessary to deploy on AWS using EC2. I can also rig up a CDN to work seemlessly with the app using S3 and Cloudfront. I have built GIS applications using GeoDjango and PostGIS, and I have constructed social video apps by implementing Encoding.com as a service to prepare raw video files for consumption on the web. I am also moderately proficient in programming PHP, Java, and C#. I have built web apps in PHP, and desktop apps in Java and C#. I have dabbled with Android applications and iPhone apps, but nothing I would show off. I have experience doing SEO, social media marketing, and content marketing. Many of my clients have needed their apps promoted after they were built, and I was always happy to oblige when I could. I have also worked with biometrics technology including fingerprints for government contractors. This was as much a business analyst role as it was a programming gig, as I had to help answer RFPs, make checklists, and work around reems and reems of regulations to build applications that met very large bureaucratic requirements. I only have two real requirements for my next gig(s): 1) Work remotely. I live in North East Ohio, and I don't plan on leaving, but I wouldn't mind traveling one or two weeks out of every month to service clients who need on-site help. 2) $60.00hr-$∞ USD contracting rate. So what should I do for the next 30 days to achieve this? Should I target some large company and learn the requisite buzzwords to impress them? Should I learn some new language or technology? Polish some skill that I already have? Should I build something using my current skillset, or with some new technology? Should I put a website for my consultancy together to market myself? Should I do that using latest technology x, y, and z? Or should I just slap something up on Tumblr? I'm willing to do anything (moral) over the next 4 weeks to put myself into a position to maximize my income, and I'm open to all and every idea Programmers users may have. Let me hear them.

  • New grad; To overcome complete lack of experience, should I ditch a creative pet project in lieu of one that would demonstrate more applicable skills?

    - by Hart Simha
    I am currently working on a project on github that I think would be a good demonstration of my initiative, creativity and enthusiasm. It is an educational game I am developing in pygame that enables the user to learn to improve their development productivity by using vim, specifically with python, though learning to code faster with vim should be transferable to any language. I think this is something that might have a mass appeal and benefit to a lot of people in a measurable way. -However- I am graduating from college in a month (my degree is computer science with a minor in English), with no experience that is relevant to helping me get any kind of job in the field, and a gpa that doesn't tout my merits. I could pursue a career in game development, but it's not necessarily what I'm most interested in, and see myself applying to startups around the country. To the places I am looking at applying, showing that I have experience with pygame is going to be largely irrelevant, except in demonstration of my ability to code, period. A lot of skills that ARE more marketable, such a data modeling, GIS, mobile application, development, javascript, .net framework, and various web development technologies, are not going to be showcased by this project (on the upside, employers do like to see familiarity with git and python). I'm wondering if I should sink all my free time in the next couple of months into this project, since I'm motivated and interested in it, and if the value of being able to demonstrate ambition and 'good ideas' (for lack of a better term, and in my own opinion) will compensate for the absence of demonstrating more sought-after skills. I am probably at a point where I should either commit fully to this project now, or put it on the backburner in favor of something else, and I am leaning towards continuing with what I am already working on, because I think it's a great idea, and something achievable to me with enough dedication over the next couple months. But the most important thing to me is being able to get a job out of college, which I am exceedingly concerned about as the professional landscape which I am navigating for the first time is a lot more intimidating than I could have anticipated, with almost every job (even short-term contract positions) requiring years of experience which I lack. So in brief, the common denominator to answering the question "How can I overcome experience requirements for a job" seems to be "Show off your own project." I want to know WHICH project I should work on to best increase my chances of getting a job out of college, keeping in mind that I have no experience. I believe this question is applicable to any new grad that lacks demonstrable experience.

  • Is IE9 a modern browser?

    - by anirudha
    Is IE9 a modern browser? i show you a post who compare IE as well as they compare chrome. Is IE9 a modern browser? well Are you thing that they make something bettter then thing another that what Firefox and chrome do whenever Microsoft do this. that's point that Microsoft always blast IE because they make version upon version not upon update like Firefox make 3.6.14 after 3.6.13 and chrome give update soon as possible but IE not come soon. they will thing for making 10 instead of giving update on 9. well what they tell us new. they make fool public everytime i believe they make fool public as same as today they maked for version 9 they show developer tool in 9 have three new tabs or pael are this enough. whenever  in chrome and firefox their is many plugin who make development easier IE still have a developer tool who not have enough power like Firebug in Firefox. they show performance but forget luna user [window xp] and their IE never runs on other plateform but chrome and firefox can. no customization in IE whenever chrome and firefox have uncountable plugin and addons. show features now in IE who already implemented in firefox very early. well their is no rule that static goes right every time not sure that IE and Firefox both are right in their language. their is no one predict what thing goes better in future. so well keep a thing in mind never wasted time and also thing to make task easier even you need to use sollution opensource or closesoure inside or outside MS does not matter. well everyone tell you much more then they do even IE and some other. they never tell you this thing not in IE but in another can be found they never tell you use other whenever you need a thing and never can be found in their software. you need to more beware of IE because they make them commorcial not really for public if really then why they stop wxp user to use them as well firefox and chrome never force. because they need a thing that force more then more copy of windows sale. so they thing to add a thing in window 8. the IE9 they thing to make before that they thing to make  this for windows 8. they always force user to purchase this for this. this for this. and this trick sell their software. well outside MS Mozilla and Chrome all behave better with user and their feedback. they respect user their privacy and feedback. if you not believe that how much problem you found in IE and they got solved soon as in chrome and firefox bug kill soon. because IE not opensource we need to  boycutt them secondly their is no customization then they make user task easier even with twitter and facebook.

    Originally posted on: http://geekswithblogs.net/dvroegop/archive/2014/08/20/our-own-daily-wtf.aspxIf you're a developer, you've probably heard of the website the DailyWTF. If you haven't, head on over to http://www.thedailywtf.com and read. And laugh. I'll wait. Read it? Good. If you're a bit like me probably you've been wondering how on earth some people ever get hired as a software engineer. Most of the stories there seem to weird to be true: no developer would write software like that right? And then you run into a little nugget of code one of your co-workers wrote. And then you realize: "Hey, it happens everywhere!" Look at this piece of art I found in our codebase recently: public static decimal ToDecimal(this string input) {     System.Globalization.CultureInfo cultureInfo = System.Globalization.CultureInfo.InstalledUICulture;     var numberFormatInfo = (System.Globalization.NumberFormatInfo)cultureInfo.NumberFormat.Clone();     int dotIndex = input.IndexOf(".");     int commaIndex = input.IndexOf(",");     if (dotIndex > commaIndex)         numberFormatInfo.NumberDecimalSeparator = ".";     else if (commaIndex > dotIndex)         numberFormatInfo.NumberDecimalSeparator = ",";     decimal result;     if (decimal.TryParse(input, System.Globalization.NumberStyles.Float, numberFormatInfo, out result))         return result;     else         throw new Exception(string.Format("Invalid input for decimal parsing: {0}. Decimal separator: {1}.", input, numberFormatInfo.NumberDecimalSeparator)); }  Me and a collegue have been looking long and hard at this and what we concluded was the following: Apparently, we don't trust our users to be able to correctly set the culture in Windows. Users aren't able to determine if they should tell Windows to use a decimal point or a comma to display numbers. So what we've done here is make sure that whatever the user enters, we'll translate that into whatever the user WANTS to enter instead of what he actually did. So if you set your locale to US, since you're a US citizen, but you want to enter the number 12.34 in the Dutch style (because, you know, the Dutch are way cooler with numbers) so you enter 12,34 we will understand this and respect your wishes! Of course, if you change your mind and in the next input field you decide to use the decimal dot again, that's fine with us as well. We will do the hard work. Now, I am all for smart software. Software that can handle all sorts of input the user can think of. But this feels a little uhm, I don't know.. wrong.. Or am I too old fashioned?
