• Seeking solution for printing-reporting .NET

  - by Parhs

  I am developing an application that prints in separate threads in extreme cases about 20-25 pages per minute to various thermal printers. Currently templates for these are XAML xps documents. All printers have graphics drivers that support EMF/GDI printing. So GDI-EMF is done by operating system resulting in slower performance. Sending raw text for printing is another good solution but doesnt work always , because some clients have old chinese thermal printer that nobody support thus impossible to change codepage / emulation. So it doesnt work always. Also most computers running my software are low end ATOM CPU. So I am thinking to return to GDI, EMF printing and have both Text-Only reports and EMF reports. Another reason i want EMF is because here receipts are signed by Electronic Fiscal Memory device.Most of these dont do good job extracting text from XPS as they dont follow the standard but how windows convert GDI to XPS.Even with text-only mode some of them dont support all character encodings and are impossible to send paper cut command after the sign. I know that using a reporting engine would solve rendering problem but I dont want to buy one. All I want is to be able to show tabular data and insert an image and replaced text.I know there is StringTemplate that could do the generation of template but the problem is i should parse somehow the template and render it using GDI commands. Is there any other solution/approach for this ? Or is there anything ready ?

• Huawei e303c data-card not working for Ubuntu 11.04?

  - by Umashankar

  Cheers to you. I got a problem in making a Mobile-BroadBand connection in Ubuntu 11.04, using 'Huawei e303c' usb data-card. I'm using Tata Docomo 3G sim-card (India, circle: Maharastra). My observations: 1.) I installed the device's driver 'Mobile-Partner For Linux'(which came up with the device). But it is not detecting my device. 2.) In Network Manager, Adding a Mobile-BroadBand connection is not able to detect the device (with or without the device's driver installed). 3.)I tried softwares like usb_modeswitch, gnomeppp, wvdial, sakis3G and followed their guidelines. These too didn't work. 4.) Without the driver, the system is able to identify the device (Mobile-Partner icon comes-up, that leads to driver setup files). But after installing the driver, nothing comes-up there. 5.) In all the above cases, when 'lsusb' cmd is fired, the prompt shows the connected data card (as 'DEVICE_ID:VENDOR_ID Huawei Technologies Ltd.,'). This is my problem. Give a solution to get my device connected. -Umash

• Introducing a (new) test method to a team

  - by Jon List

  A couple of months ago i was hired in a new job. (I'm fresh out of my Masters in software engineering) The company mainly consists of ERP consultants, but I was hired in their fairly small web department (6 developers), our main task is ERP/ecom integration (ERP-integrated web shops). The department is growing, and recently my manager asked me to start thinking about introducing tests to the team, i love a challenge, but frankly I'm a bit scared (I'm the least experience member of the team). Currently the method of testing is clicking around in the web shop and asking the customer if the products are there, if they look okay, and if orders are posted correctly to the ERP. We are getting a lot of support cases on previous projects, where a customer or a customer's customer have run into errors, which - i suppose - is why my manager wants more structured testing. Off the top of my head, I though of some (obvious?) improvements, like looking at the requirement specification, having an issue tracker, enabling team members to register their time on a "tests"-line on the budget, and to circulate tasks amongst members of the team. But as i see it we have three main challenges: general website testing. (javascript, C#, ASP.NET and CMS integration tests) (live) ERP integration testing (customers rarely want to pay for test environments). adopting a method in the team I like the responsibility, but I am afraid that I'm in a little bit over my head. I expect that my manager expects me to set up some kind of workshop for the team where I present some techniques and ideas and where we(the team) can find some solutions together. What I learned in school was mostly unit testing and program verification, not so much testing across multiple systems and applications. What I'm looking for here, is references/advice/pointers/anecdotes; anything that might help me to get smarter and to improve the current method of my team. Thanks!! (TL;DR: read the bold parts)

• Is it OK to use dynamic typing to reduce the amount of variables in scope?

  - by missingno

  Often, when I am initializing something I have to use a temporary variable, for example: file_str = "path/to/file" file_file = open(file) or regexp_parts = ['foo', 'bar'] regexp = new RegExp( regexp_parts.join('|') ) However, I like to reduce the scope my variables to the smallest scope possible so there is less places where they can be (mis-)used. For example, I try to use for(var i ...) in C++ so the loop variable is confined to the loop body. In these initialization cases, if I am using a dynamic language, I am then often tempted to reuse the same variable in order to prevent the initial (and now useless) value from being used latter in the function. file = "path/to/file" file = open(file) regexp = ['...', '...'] regexp = new RegExp( regexp.join('|') ) The idea is that by reducing the number of variables in scope I reduce the chances to misuse them. However this sometimes makes the variable names look a little weird, as in the first example, where "file" refers to a "filename". I think perhaps this would be a non issue if I could use non-nested scopes begin scope1 filename = ... begin scope2 file = open(filename) end scope1 //use file here //can't use filename on accident end scope2 but I can't think of any programming language that supports this. What rules of thumb should I use in this situation? When is it best to reuse the variable? When is it best to create an extra variable? What other ways do we solve this scope problem?

• Strategies for managUse of types in Python

  - by dave

  I'm a long time programmer in C# but have been coding in Python for the past year. One of the big hurdles for me was the lack of type definitions for variables and parameters. Whereas I totally get the idea of duck typing, I do find it frustrating that I can't tell the type of a variable just by looking at it. This is an issue when you look at someone else's code where they've used ambiguous names for method parameters (see edit below). In a few cases, I've added asserts to ensure parameters comply with an expected type but this goes against the whole duck typing thing. On some methods, I'll document the expected type of parameters (eg: list of user objects), but even this seems to go against the idea of just using an object and let the runtime deal with exceptions. What strategies do you use to avoid typing problems in Python? Edit: Example of the parameter naming issues: If our code base we have a task object (ORM object) and a task_obj object (higher level object that embeds a task). Needless to say, many methods accept a parameter named 'task'. The method might expect a task or a task_obj or some other construct such as a dictionary of task properties - it is not clear. It is them up to be to look at how that parameter is used in order to work out what the method expects.

• Dealing with an Idiot [closed]

  - by inspectorG4dget

  I'm a 4th year University Computer Science student, and I have this problem, that I don't seem to be able to find a straight answer to: As a 4th year computer science student, I spend more time in the computer lab on campus, than even my own home. This means that getting along with everyone else here is very important to me. In most cases, this is not an issue because my interactions with almost all the people here fall into one of the following categories: Let me help you, junior Hi fellow student in a course I'm taking, I'm having trouble with this assignment question. Can you give me a hint as to how you solved it? Hi fellow student in a course I'm taking, This is how I solved the problem that you're stuck on. Hope it helps Hi fellow student, I noticed that you're working on a project, using a library that I'm interested in. Can we setup a time so I can learn about this library from you? This model of interaction works very well for me. However, there is one fellow student, who manages to make my life hell beyond all of this (his name is not important, let's just call him "Sam"). He seems to be always (pardon my crass description) high and completely unwilling to contribute to a constructive, academic conversation. He's a pretty smart guy, but just comes across as (I hate to say something like this about a fellow student, but) an imbecile. He also has ignorant opinions on important topics, some of which pertain to my specialization (AI, NLP, etc), and when I try to explain to him why he's wrong, all he does is insult me and put me in a foul mood. I have tried ignoring him (sitting somewhere else in the lab, headphones, etc), but he seems to like doing this because he approaches me and no amount of "leave me alone" seems to do the trick. Can anyone please suggest to me how to deal with this man in a civil way? Thank you

• Check parameters annotated with @Nonnull for null?

  - by David Harkness

  We've begun using FindBugs with and annotating our parameters with @Nonnull appropriately, and it works great to point out bugs early in the cycle. So far we have continued checking these arguments for null using Guava's checkNotNull, but I would prefer to check for null only at the edges--places where the value can come in without having been checked for null, e.g., a SOAP request. // service layer accessible from outside public Person createPerson(@CheckForNull String name) { return new Person(Preconditions.checkNotNull(name)); } ... // internal constructor accessed only by the service layer public Person(@Nonnull String name) { this.name = Preconditions.checkNotNull(name); // remove this check? } I understand that @Nonnull does not block null values itself. However, given that FindBugs will point out anywhere a value is transferred from an unmarked field to one marked @Nonnull, can't we depend on it to catch these cases (which it does) without having to check these values for null everywhere they get passed around in the system? Am I naive to want to trust the tool and avoid these verbose checks? Bottom line: While it seems safe to remove the second null check below, is it bad practice? This question is perhaps too similar to Should one check for null if he does not expect null, but I'm asking specifically in relation to the @Nonnull annotation.

• How exactly is an Abstract Syntax Tree created?

  - by Howcan

  I think I understand the goal of an AST, and I've build a couple of tree structures before, but never an AST. I'm mostly confused because the nodes are text and not number, so I can't think of a nice way to input a token/string as I'm parsing some code. For example, when I looked at diagrams of AST's, the variable and its value were leaf nodes to an equal sign. This makes perfect sense to me, but how would I go about implementing this? I guess I can do it case by case, so that when I stumble upon an "=" I use that as a node, and add the value parsed before the "=" as the leaf. It just seems wrong, because I'd probably have to make cases for tons and tons of things, depending on the syntax. And then I came upon another problem, how is the tree traversed? Do I go all the way down the height, and go back up a node when I hit the bottom, and do the same for it's neighbor? I've seen tons of diagrams on ASTs, but I couldn't find a fairly simple example of one in code, which would probably help.

• 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.

• How can I set my resolution to 1280x1024 on an Acer Aspire Revo 3700?

  - by torbengb

  I've just set up a new nettop computer (Acer Aspire Revo 3700: CPU:Atom D525, GPU:Nvidia ION2). I've just made a clean install of Ubuntu 10.10 using the standard USB pendrive method. Almost everything works OK, but the graphics are not OK: the recommended Nvidia driver is activated but the monitor is not detected, so the resolution is wrong. How can I make Ubuntu detect my monitor? How can I get the proper resolution (1280x1024) in Ubuntu? I know that my monitor is not a CRT but an LCD: it's a BenQ, model T905, with 1280x1024 resolution at 60Hz, connected via a normal VGA cable. DVI or HDMI is not an option. When I go to SystemPrefsMonitors, I get: It appears that your graphics driver does not support the necessary extensions to use this tool. Do you want to use your graphics driver vendor's tool instead? YES NO If I say NO then I get a window: or for YES I get this: In both cases I don't see that I can fix this problem. The main reason for getting this new computer was that I was sick of having graphics problems on the old one with a very ugly solution that didn't give me hardware support - but at least I got the resultion. Why is this so difficult... sigh!

• Direct IO enhancements in OVM Server for SPARC 2.2(a.k.a LDoms2.2)

  - by user12611315

  The Direct I/O feature has been available for LDoms customers since LDoms2.0. Apart from the latest SR-IOV feature in LDoms2.2, it is worth noting a few enhancements to the Direct I/O feature. These are: Support for Metis-Q and Metis-E cards. These cards are highly requested for support and are worth mentioning because they are the only combo cards containing both FibreChannel and Ethernet in the same card. With this support, a customer can have both SAN storage and network access with just one card and one PCIe slot assigned to a logical domain. This reduces cost and helps when there are less number of slots in a given platform. The following are the part numbers for these cards. I have tried to put the platforms on which each card is supported, but this information can get quickly outdated. The accurate information can be found at the Support Document.  Card Name  Part Number  Platforms Metis-Q: StorageTek Dual 8Gb Fibre Channel Dual GbE ExpressModule HBA, QLogic SG-XPCIEFCGBE-Q8-N  SPARC T3-4, T4-4 Metis-E: StorageTek Dual 8Gb Fibre Chanel Dual GbE ExpressModule HBA, Emulex SG-XPCIEFCGBE-E8-N SPARC T3-4, T4-4  Additional cards added to the portfolio of supported cards. This is mainly Powerville based Ethernet cards, the part numbers for these cards as below:  Part Number  Description  7100477 Sun Quad Port GbE PCI Express 2.0 Low Profile Adapter, UTP  7100481 Sun Dual Port GbE PCI Express 2.0 Low Profile Adapter, MMF  7100483 Sun Quad Port GbE PCI Express 2.0 ExpressModule, UTP  7110486 Sun Quad Port GbE PCI Express 2.0 ExpressModule, MMF    Note:  Direct IO feature has a hard dependency on the Root domain(PCIe bus owner, here Primary domain). That is, rebooting the Root domain for any reason may impact the logical domains having PCIe slots assigned with Direct IO feature. So rebooting a root domain need to be carefully managed. Also apply the failure-policy settings as described in the admin guide and release notes to deal with unexpected cases.

• An Interview with JavaOne Rock Star Martijn Verburg

  - by Janice J. Heiss

  An interview with JavaOne Rock Star Martijn Verburg, by yours truly, titled “Challenging the Diabolical Developer: A Conversation with JavaOne Rock Star Martijn Verburg,” is now up on otn/java. Verburg, one of the leading movers and shakers in the Java community, is well known for his ‘diabolical developer” talks at JavaOne where he uncovers some of the worst practices that Java developers are prone to. He mentions a few in the interview: * “A lack of communication: Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson.* No source control: Some developers simply store code in local file systems and e-mail the code in order to integrate their changes; yes, this still happens.* Design-driven design: Some developers are inclined to cram every design pattern from the Gang of Four (GoF) book into their projects. Of course, by that stage, they've actually forgotten why they're building the software in the first place.” He points to a couple of core assumptions and confusions that lead to trouble: “One is that developers think that the JVM is a magic box that will clean up their memory and make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try to force Java (the language) to do something it's not very good at, such as rapid Web development. So you get a proliferation of overly complex frameworks, libraries, and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!” Verburg has many insightful things to say about how to keep a Java User Group (JUG) going, about the “Adopt a JSR” program, bugathons, and much more. Check out the article here.

• Sucking Less Every Year?

  - by AdityaGameProgrammer

  Sucking Less Every Year -Jeff Atwood I had come across this insightful article.Quoting directly from the post I've often thought that sucking less every year is how humble programmers improve. You should be unhappy with code you wrote a year ago. If you aren't, that means either A) you haven't learned anything in a year, B) your code can't be improved, or C) you never revisit old code. All of these are the kiss of death for software developers. How often does this happen or not happen to you? How long before you see an actual improvement in your coding ? month, year? Do you ever revisit Your old code? How often does your old code plague you? or how often do you have to deal with your technical debt. It is definitely very painful to fix old bugs n dirty code that we may have done to quickly meet a deadline and those quick fixes ,some cases we may have to rewrite most of the application/code. No arguments about that. Some of the developers i had come across argued that they were already at the evolved stage where their coding doesn't need improvement or cant get improved anymore. Does this happen? If so how many years into coding on a particular language does one expect this to happen? Related: Ever look back at some of your old code and grimace in pain?

• Trying to install Canon LBP7750Cdn driver on Ubuntu 12.04

  - by Gideon

  I'n new to Ubuntu/Linux and had significant difficulties while attempting to configure my printer to work. The automatic driver pairing wizard which Ubuntu uses to identify and install the appropriate drivers did not find my printer's driver. I managed to get it to print when I manually select the generic configuration and checked the PCL6 configuration. However, the printer driver wizard does provide a list of Canon printers and actually do specify my printer as LBP7750C (minus the "dn" at the end, I'm assuming its because duplex ability and networking is not present on all the models - I'm not sure if this could be the source of the problem), but in selecting this option and trying to print I receive this message: Idle - /usr/lib/cups/filter/foomatic-rip failed I searched for this similar problem which other users might have encountered, but while there where plenty of such cases, they all had different resolutions and were all related to HP printers. Canon actually do provide a driver for my printer, but it comes with no installation instructions unless you consider yourself an experienced CUPS guru. Seriously. If anyone can help me solve this foomatic-rip failed problem I'd be really grateful - and I'm sure many other folks too. [BTW, can't Canonical fix this type of thing for the next Ubuntu release? - I't seems like a small problem but it causes many problems and countles hours of production time loss.] Thanks in advance.

• Unable to mount an LVM Hard-drive after upgrade

  - by Bruce Staples

  I imagine this is a basic gotcha ... but I can't see it. I have a system with 2(physical) harddrives. The boot system (/dev/sda) was running 10.04 & the second drive (/dev/sdb) was just a mounted filesystem. I did a clean load of Ubuntu 12.04 overwriting /dev/sda (not an upgrade) & now cannot mount the second drive. so I do not know what to enter it into the fstab ... I had expected to use: /dev/sdb /tera ext4 defaults 0 2 But even manual mounting fails (I also have tried various "-t" options on the off chance!) sudo mount -t ext4 /dev/sdb1 /tera mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Output from disk queries indicate that it is a Linux LVM & a healthy disk still. sudo lshw -C disk *-disk:0 description: ATA Disk product: WDC WD5000AACS-0 vendor: Western Digital physical id: 0 bus info: scsi@2:0.0.0 logical name: /dev/sda version: 01.0 serial: WD-WCASU1401098 size: 465GiB (500GB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 signature=00015a55 *-disk:1 description: ATA Disk product: WDC WD10EADS-00L vendor: Western Digital physical id: 1 bus info: scsi@3:0.0.0 logical name: /dev/sdb version: 01.0 serial: WD-WCAU47836304 size: 931GiB (1TB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 sudo fdisk -l Disk /dev/sda: 500.1 GB, 500106780160 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976771055 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00015a55 Device Boot Start End Blocks Id System /dev/sda1 * 2048 972580863 486289408 83 Linux /dev/sda2 972582910 976769023 2093057 5 Extended /dev/sda5 972582912 976769023 2093056 82 Linux swap / Solaris Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 1 1953525167 976762583+ 8e Linux LVM LVM doesn't appear to be an option for mount or fstab. ... and here's a Smart data Screenshot from Disk Utility.

• ODI 11g - Faster Files

  - by David Allan

  Deep in the trenches of ODI development I raised my head above the parapet to read a few odds and ends and then think why don’t they know this? Such as this article here – in the past customers (see forum) were told to use a staging route which has a big overhead for large files. This KM is an example of the great extensibility capabilities of ODI, its quite simple, just a new KM that; improves the out of the box experience – just build the mapping and the appropriate KM is used improves out of the box performance for file to file data movement. This improvement for out of the box handling for File to File data integration cases (from the 11.1.1.5.2 companion CD and on) dramatically speeds up the file integration handling. In the past I had seem some consultants write perl versions of the file to file integration case, now Oracle ships this KM to fill the gap. You can find the documentation for the IKM here. The KM uses pure java to perform the integration, using java.io classes to read and write the file in a pipe – it uses java threading in order to super-charge the file processing, and can process several source files at once when the datastore's resource name contains a wildcard. This is a big step for regular file processing on the way to super-charging big data files using Hadoop – the KM works with the lightweight agent and regular filesystems. So in my design below transforming a bunch of files, by default the IKM File to File (Java) knowledge module was assigned. I pointed the KM at my JDK (since the KM generates and compiles java), and I also increased the thread count to 2, to take advantage of my 2 processors. For my illustration I transformed (can also filter if desired) and moved about 1.3Gb with 2 threads in 140 seconds (with a single thread it took 220 seconds) - by no means was this on any super computer by the way. The great thing here is that it worked well out of the box from the design to the execution without any funky configuration, plus, and a big plus it was much faster than before, So if you are doing any file to file transformations, check it out!

• Personal Software Process (PSP1)

  - by gentoo_drummer

  I'm trying to figure out an exercise but it doesn't really makes to much sense.. I'm not asking someone to provide the solution. just to try and analyse what needs to be done in order to solve this. I'm trying to understand which PSP 1.0 1.1 process I should use. PROBE? Or something else? I would greatly appreciate some help on this one from someone that has experience with the Personal Software Process Methodology.. Here is the question. For the reference case (“code1.c”), the following s/w metrics are provided: man-hours spent in implementation phase (per-module): 2,7 mh/file man-hours spent in testing phase (per-module): 4,3 mh/file estimated number of bugs remaining (per-module): 0,3 errors/function, 4 errors/module (remaining) Based on the corresponding values provided for the reference case, each of the following tasks focus on some s/w metrics to be estimated for the test case (“code2.c”): [25 marks] (estimated) man-hours required in implementation phase (per-module) [8 marks] (estimated) man-hours required in testing phase (per-module) [8 marks] (estimated) number of bugs remaining at the end of testing phase (per-module) [9 marks] Tasks 4 through 6 should use the data provided for the reference case within the context of Personal Software Process level-1 (PSP-1), using them as a single-point historic data log. Specifically, the same s/w metrics are to be estimated for the test case (“code2.c”), using PSP as the basic estimation model. In order to perform the above listed tasks, students are advised to consider all phases of the PSP software development process, especially at levels PSP0 and PSP1. Both cases are to be treated as separate case-studies in the context of classic s/w development.

• How does Wikipedia's SEO work?

  - by Josh Siegl

  i'm sorry if this question is misplaced or doesn't belong here. I'm currently developing an app for android and IOS and of course i'm thinking about the best ways to market it. Last night I Google'd somebody else's app and the third link in was a Wikipedia page on it, I never even thought of apps having Wikipedia pages, but alas there it was. And of course it was very helpful in determining exactly what the app did and in what cases it was useful for (something that's absolutely crucial for potential customers to understand). So then I got to thinking that I should create a Wiki for my app, but how does Wikipedia apply SEO? I know that the question could be overly complicated or specific, i'm just looking for general answers. For instance when somebody Google's my app, where does Wikipedia display on the results? When I create a Wiki for my app, how do I ensure that the Wikipedia page shows in the search results (is there any way to do that? ) I'm sure i'll find all of this out later when I create a Wiki for my app, I guess i'm just asking this out of curiosity. So how does Wikipedia's search engine optimization work? (on a page by page basis)

  - by svdoever

  We released DualLayout which enables advanced web design with the power of SharePoint. DualLayout and a demo site can be downloaded from the DualLayout product page. This blogpost contains detailed instructions on installing the demo site. The demo site is based on the site http://opensourcefood.com. The demo site requires internet access because it still links to pages and resources of the real site. Execute the following steps to install the demo site: Copy the OpenSourceFoodDemo.zip file to your SharePoint Server 2010 Make sure that the zip file in “unblocked”, otherwise files are assumed from other computer (right-click on zip file, press “Unblock” button if available) Unzip the OpenSourceFoodDemo.zip to a folder of your choice (c:\OpenSourceFoodDemo) Open the SharePoint  Start->Microsoft SharePoint 2010 Products->SharePoint 2010 Management Shell Change directory to the unzip folder (cd c:\OpenSourceFoodDemo) Start install script: .\InstallDemoSite.ps1 Answer the questions, default values in most cases ok. A little guidance: Question: Give credentials for the account that will be used for the application pool Answer: use for example same account as used for the application pool of your SharePoint site (lookup in IIS Manager) Question: Give credentials for the account that will be used for the application pool Answer: Use same account you are currently logged in with The demo site is made available through a backup and restore. The SharePoint Server 2010 installation must be patched to a level equal or higher to the update level on the SharePoint Server used to create the backup. If you get errors with respect to restore check http://technet.microsoft.com/en-us/sharepoint/ff800847.aspx for downloading the latest cumulative update.

• Adaptive Case Management Modeling with CMMN by Jessica Ray

  - by JuergenKress

  A new version of Oracle BPM Suite 11.1.1.7 with Adaptive Case Management (ACM) is now available, so what will that mean for requirements gathering? BPM project requirements can be documented using Business Process Model and Notation (BPMN 2.0). For ACM, there is a new notation in the works. It is called Case Management Model and Notation (CMMN). For now, this notation isn’t included as a modeling tool in the new version of Oracle BPM Suite 11.1.1.7 with ACM, but it is possible that a modeling tool could be included in a future release. What is CMMN? CMMN is a standard intended to capture the common elements that Case Management Products use, the same way that BPMN is a standard for BPM products (such as Oracle BPM). CMMN is created by the Object Management Group (OMG) and is still in the beta version. In April 2014, OMG released the second beta version the CMMN 1.0, and the most recent version is available here. CMMN captures some of the elements that are commonly used when talking about ACM such as Cases, Milestones, and Tasks. It also introduces some elements that you may not automatically hear when talking about ACM such as Stages, Events, and Decorators. Here is a quick summary at a few (but not all) of the elements of CMMN taken from the CMMN spec. A Few CMMN Elements Read the complete article here SOA & BPM Partner Community For regular information on Oracle SOA Suite become a member in the SOA & BPM Partner Community for registration please visit www.oracle.com/goto/emea/soa (OPN account required) If you need support with your account please contact the Oracle Partner Business Center.

• Why does my Canon printer print document pages at ~25% size?

  - by Erlend Alvestad

  I'm using a Canon PIXMA MP250, and I'm running 12.04 LTS. The printer's been working fine for the couple of months I've been a Linux user. That is, until today. I just printed a 1-page ODT document from LibreOffice. Instead of filling the sheet, the document occupies only a little less than 25% of the paper, in the top left corner, and the text has also shrunk to something like 5pt. I looked at the paper format settings for the document and printer, which were set to "letter". I changed these to "A4", hoping that would solve the issue. There was no change, however. I tried printing a different document in LibreOffice and got the same result. I tried exporting the original document to PDF and printing it through Document Viewer. Same result. I then printed a web page from Google Chrome. No formatting problems there. In all cases the print preview looks fine.
