• Installed Paragon HFS+ for Windows 8, now my pc won't recognize the external firewire drive

  - by Steve

  I'm not incredibly knowledgeable about computers and I really need some help. Just got a Seagate external firewire drive this morning. I downloaded the necessary pc driver (Paragon HFS+ for Windows 8) through their website per the instructions that came with the drive. After installation, I restarted and the pc recognized the firewire drive just fine. About three hours into copying files from my pc to the firewire drive, it gave me an error and told me the files couldn't be copied. When I clicked to get out of the message, the computer crashed. After an hour of it trying to repair itself in safe mode, it restored me to an earlier version before the system crashed. Here's my current dilemma: The Paragon HFS+ is still showing up in my programs as installed, but the Device Manager is not recognizing the drive. When I try to uninstall and reinstall Paragon, it interrupts me with a message saying "The setup must update files or services that cannot be updated while the system is running" and basically gives me the finger. I have no idea what to do now, as it won't let me uninstall and reinstall Paragon, and I have no idea why it crashed my computer in the first place. Is there possibly another Mac - PC firewire driver I can try downloading instead? I really don't know what I'm doing and any help would be greatly appreciated.

• Customisation / overriding of the Envelop ecs files

  - by Dheeraj Kumar M

  There are few usecases where the requirement is to customise the envelop information (Interchange/Group ecs file). Such scenarios might be required to be used for only few of the customers. Hence, in addition to the default seeded envelop definitions, it also required to upload the customised definitions. Here is the steps for achieving the same. 1. Create only the Interchange ecs and save 2. Create only the group ecs and save 3. Use the same in B2B 1. Create only the Interchange ecs and save :       Open the document editor and select the required version and doctype. During creating new ecs, ensure to select the checkbox for insert envelop.       Once created, delete the group and transactionset nodes and retain only the Interchange ecs nodes, including both header and trailer. Save this file. 2. Create only the group ecs and save       After creating the ecs file as mentioned in steps of Interchange creation, delete the Interchange and transactionset nodes and retain only the group ecs nodes, including both header and trailer. Save this file. 3. Use the same in B2B       These newly created ecs can be used in B2B by 2 ways.              a. By overriding at the trading partner Level:              This will be very useful when the configuration is complete and then need to incorporate the customisation. In this case, just select the Trading partner - document - select the document which need to be customised.              Upload the newly created Interchange and group ECS files under the Interchange and group tabs respectively and re-deply the associated agreement.              The advantage of this approach is              - Flexibility to add customised envelop definitions to the partners              - Save the re-work of design time effort.              b. By adding another document definition in Administration - document screen:              This scenario can be used if there is no configuration done at the trading partner level. Create the required document revision and overtide the Interchange and group ECS files under the Interchange and group tabs respectively. Add the document in Trading partner - document. Create and deploy the agreements

• E-Business Suite 11.5.10 Fenntartó Támogatással és 12.1 Meghosszabbított Támogatással kapcsolatos külön bejelentés

  - by user552636

  Igaz, az idei Oracle Open World (OOW) már régen volt, de akkor ez a blog még nem létezett. Ugyanakkor azóta többektol kaptam kérdést az OOW-n tett E-Business Suite támogatással kapcsolatos bejelentés értelmezésére vonatkozóan. Ezért gondoltam, hasznos lehet a magyar felhasználók számára, ha írok pár sort a bejelentésrol. Az E-Business Suite (EBS) 11.5.10 verzióhoz kapcsolódó bejelentés: Az Oracle Élettartam Támogatási modellje szerint ez a verzió általánosan 2004. novembertol volt elérheto, melyre az Oracle 2010. november 30-ig biztosított Premier Támogatást, 2010. December 1-tol 2013. november végéig pedig Meghosszabbított Támogatást nyújt. Jövo év december 1-tol az EBS 11.5.10 verzió Fenntartó Támogatás szakaszba kerül. Fenntartó Támogatás szakaszban az újonnan felfedezett bug-okat már nem javítja a Fejlesztés. A bejelentés szerint Oracle a 11.5.10 esetében kivételt tesz és a 2013. december 1-tol 2014. november 30-ig terjedo idoszakban az éles üzemet érinto 1-es súlyossági szintu problémák esetében biztosítani fogja új hibák javítását is. Amire ügyelni érdemes, a rendszer a  Doc ID 883202.1 My Oracle Support dokumentumban részletezett minimum patch szinten kell legyen.   Ez a plusz szolgáltatás nem befolyásolja a támogatási díjat. Az E-Business Suite (EBS) 12.1 verzióhoz kapcsolódó bejelentés   Az EBS 12.1 verzió Meghosszabbított támogatásának eredetileg mehírdetett idoszaka 2014. május 1. – 2017. április 30. volt. Oracle ezt az idoszakot 19 hónappal megtoldotta, így ennek a verziónak a Meghosszabbított Támogatása 2018. december 31-ig tart majd. További jó hír e verziót használó Ügyfeleink számára, hogy a Meghosszabbított Támogatás emelt díjától az Oracle eltekint. Standard Oracle árazás szerint a Meghosszabbított Támogatás elso évében a szolgáltatási díj a Premier Támogatás díjának 110%-a, a második, ill. harmadik években a Premier Támogatás díjának 120%-a. Oracle jelen esetben a plusz 10%-tól, ill. a plusz 20 %-tól eltekint. Íly módon a Meghosszabbított Támogatást Oracle a Premier Támogatás díjért biztosítja majd. Amire ügyelni érdemes, a rendszer a  Doc ID 1195034.1 My Oracle Support dokumentumban részletezett minimum patch szinten kell legyen.   Az idoszakok egyszerubb megértése érdekében az alábbi grafikonon ábrázoltam a szóban forgó verziók támogatásának egyes szakaszait.

• Windows Azure Virtual Machines - Make Sure You Follow the Documentation

  - by BuckWoody

  To create a Windows Azure Infrastructure-as-a-Service Virtual Machine you have several options. You can simply select an image from a “Gallery” which includes Windows or Linux operating systems, or even a Windows Server with pre-installed software like SQL Server. One of the advantages to Windows Azure Virtual Machines is that it is stored in a standard Hyper-V format – with the base hard-disk as a VHD. That means you can move a Virtual Machine from on-premises to Windows Azure, and then move it back again. You can even use a simple series of PowerShell scripts to do the move, or automate it with other methods. And this then leads to another very interesting option for deploying systems: you can create a server VHD, configure it with the software you want, and then run the “SYSPREP” process on it. SYSPREP is a Windows utility that essentially strips the identity from a system, and when you re-start that system it asks a few details on what you want to call it and so on. By doing this, you can essentially create your own gallery of systems, either for testing, development servers, demo systems and more. You can learn more about how to do that here: http://msdn.microsoft.com/en-us/library/windowsazure/gg465407.aspx   But there is a small issue you can run into that I wanted to make you aware of. Whenever you deploy a system to Windows Azure Virtual Machines, you must meet certain password complexity requirements. However, when you build the machine locally and SYSPREP it, you might not choose a strong password for the account you use to Remote Desktop to the machine. In that case, you might not be able to reach the system after you deploy it. Once again, the key here is reading through the instructions before you start. Check out the link I showed above, and this link: http://technet.microsoft.com/en-us/library/cc264456.aspx to make sure you understand what you want to deploy.

• C# coding standards” Use the const directive only on natural constants

  - by Nathan Wilfert

  I've seen these 2 guidelines in coding c# standard and I’m not sure the what the 2nd one means. With the exception of zero and one, never hard-code a numeric value; always declare a constant instead. Use the const directive only on natural constants such as the number of days of the week. 1st what is the definition of a natural constants and if the number is not a natural constants given the 1st rule how does one declare a constant in c# without the const directive? See http://www.scribd.com/doc/10731655/IDesign-C-Coding-Standard-232 for reference.

• What are the advantages of Maven when it comes to single man, educational projects

  - by Leron

  I've spend a few hours playing around with Maven + reading some stuff on the apache official site and also a few random googled articles. By this I mean that I really tried to find the answers myself - both by reading and by doing things on my own. Also maybe worth to mention that I installed the m2e plugin so most of the time I've tried things out from Eclipse and not using the command line too much. However aside from the generated project that for example prevent me from using the default package I didn't see that much of a difference with the standard way I've created my projects before try Maven. In fact I've almost decided to skip Maven for now and move on to the other technology I wanted to learn more in-depth - Hibernate, but when I start with opening the official page the first thing I've read was the recommendation to use Hibernate with Maven. That get me confused and made me taking a step back and trying once more to find what I'm obviously missing right now. As it's said in the maven.apache.. site, the true strength of Maven is shown when you work on large projects with other people, but I lack the option to see how Maven is really used in this scenario, still i think that there are maybe advantages even when it comes to working with small projects alone, but I really have difficulties to point them out. So what do you think are the advantages of Maven when it's used for small projects writing from a single person. What are the things that I should be aware of and try to exploit (I mean features offered by Maven) that can come in handy in this situations?

• How to implement a safe password history

  - by Lorenzo

  Passwords shouldn't be stored in plain text for obvious security reasons: you have to store hashes, and you should also generate the hash carefully to avoid rainbow table attacks. However, usually you have the requirement to store the last n passwords and to enforce minimal complexity and minimal change between the different passwords (to prevent the user from using a sequence like Password_1, Password_2, ..., Password_n). This would be trivial with plain text passwords, but how can you do that by storing only hashes? In other words: how it is possible to implement a safe password history mechanism?

• How to chose a develop method?

  - by Martin

  There are many academic/industrial researchs about various development methods (Scrum, XP, waterfall, ect.), telling us how to do it right and stuff. But I never saw something that suggest how to choose a method, what will be better for a given project. I know that what the developers are used to is an very important aspect. But lets say that I am assembling a new group from scratch, and that every programmer in the world is willing to work with me. :) What aspects of the project should I consider to decide between Scrum, XP, TDD, ect.? Or is that an entirely human thing, regardless of what is being developed? I said that all programmers are available, but you may comment they're knowledge about the domain, or other characteristics in the answers. E.g. "If you chose to hire people with no domain knowledge, MethodX is better than MathodY, beacause ...." is a completely welcomed answer.

• What's special about currying or partial application?

  - by Vigneshwaran

  I've been reading articles on Functional programming everyday and been trying to apply some practices as much as possible. But I don't understand what is unique in currying or partial application. Take this Groovy code as an example: def mul = { a, b -> a * b } def tripler1 = mul.curry(3) def tripler2 = { mul(3, it) } I do not understand what is the difference between tripler1 and tripler2. Aren't they both the same? The 'currying' is supported in pure or partial functional languages like Groovy, Scala, Haskell etc. But I can do the same thing (left-curry, right-curry, n-curry or partial application) by simply creating another named or anonymous function or closure that will forward the parameters to the original function (like tripler2) in most languages (even C.) Am I missing something here? There are places where I can use currying and partial application in my Grails application but I am hesitating to do so because I'm asking myself "How's that different?" Please enlighten me.

• Why are tools like git-svn that allow git to integrate with svn useful? [closed]

  - by Wes

  I have read these related questions: I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS? git for personal (one-man) projects. Overkill? ...and I understand why git is useful. What I don't understand is why tools like git-svn that allow git to integrate with svn are useful. When, for example, a team is working with svn, or any other centralised SCM, why would a member of the team opt to use git-svn? Are there any practical advantages for a developer that has to synchronize with a centralized repository?

• What are the benefits and drawback of documentation vs tutorials vs video tutorials [closed]

  - by Cat

  Which types of learning resources do you find the most helpful, for which kinds of learning and/or perhaps at specific times? Some examples of types of learning you could consider: When starting to integrate a new SDK inside an existing codebase When learning a new framework without having to integrate legacy code When digging deeper into an already-used SDK that you may not know very well yet For example - (video) tutorials are usually very easy to follow and tells a story from beginning to end to get results, but will nearly always assume starting from scratch or a previous tutorial. Therefore such a resource is useful for quick learning if you don't have legacy code around, but less so if you have to search for the best-fit to the code you already have. SDK Documentation on the other hand is well-structured but does not tell a story. It is more difficult to get to a specific larger result with documentation alone, but it is a better fit when you do have legacy code around and are searching for perhaps non-obvious ways of employing the SDK or library. Are there other forms of resources that you find useful, such as interactive training?

• Designing web-based plugin systems correctly so they don't waste as many resources?

  - by Xeoncross

  Many CMS systems which rely on third parties for much of their code often build "plugin" or "hooks" systems to make it easy for developers to modify the codebase's actions without editing the core files. This usually means an Observer or Event design pattern. However, when you look at systems like wordpress you see that on every page they load some kind of bootstrap file from each of the plugin's folders to see if that plugin will need to run that request. Its this poor design that causes systems like wordpress to spend many extra MB's of memory loading and parsing unneeded items each page. Are there alternative ways to do this? I'm looking for ideas in building my own. For example, Is there a way to load all this once and then cache the results so that your system knows how to lazy-load plugins? In other words, the system loads a configuration file that specifies all the events that plugin wishes to tie into and then saves it for future requests? If that also performs poorly, then perhaps there is a special file-structure that could be used to make educated guesses about when certain plugins are unneeded to fullfil the request. Any ideas? If anyone wants an example of the "plugin" concept you can find one here.

• On what basis would you split donation money among your open source team members without any strife?

  - by Vigneshwaran

  I am a developer of an open source project which is hosted in SourceForge. It started out as a little app then after some releases, it got more and more popular and it started consuming more time and responsibility from me. So I have enabled the donation option in SourceForge. I'm passionate to continue developing it for free but if (ever) any money comes in, how should I split it with my team? Should I split the amount equally among the number of team members? (50-50 as it is two-member team now) Number of classes, commits or any other valuable submissions by team members? Any other idea? What would you do in such situation? Please give your opinions. I hope this question will be useful for others.

• Automated unit testing, integration testing or acceptance testing

  - by bjarkef

  TDD and unit testing seems to be the big rave at the moment. But it is really that useful compared to other forms of automated testing? Intuitively I would guess that automated integration testing is way more useful than unit testing. In my experience the most bugs seems to be in the interaction between modules, and not so much the actual (usual limited) logic of each unit. Also regressions often happened because of changing interfaces between modules (and changed pre and post-conditions.) Am I misunderstanding something, or why are unit testing getting so much focus compared to integration testing? It is simply because it is assumed that integration testing is something you have, and unit testing is the next thing we need to learn to apply as developers? Or maybe unit testing simply yields the highest gain compared to the complexity of automating it? What are you experience with automated unit testing, automated integration testing, and automated acceptance testing, and in your experience what has yielded the highest ROI? and why? If you had to pick just one form of testing to be automated on your next project, which would it be? Thanks in advance.

• User Switching in XFCE 12.04 with LightDM and dumping unneeccesary Gnome libs

  - by user111120

  I'm an elder non-techie Mac-to-Linux convert trying to play the linux tech game by ear, so please be gentle! :) I am running XFCE Ubuntu 12.04 totally on a 8-gig flash drive and it's fantastic. I am starting to run into potential space issues (down to 1.0 gig free from 1.9 gigs since being installed last summer), most likely because of growing Thunderbird mail files, and this prompted my question. I just installed lightDM on my system because I want the ability to switch users in XFCE if I follow instructions on another blog. They advised using LightDM instead of GDM because LightDM doesn't download Gnome libraries. That's great since I need the space, but my question is how can I tell whether I don't already have Gnome libraries installed from other updates and such? And can I minimize having any Gnome libraries? The method for me to switch users entails creating a "fast-user-switch" file in /usr/local/bin; is there any easier way? One last thing so I din't have topen another needless thread; while experimenting I somehow lost the share folder in one of my accounts. Is there any way to get a share folder back? Thanks for any tips! Jim in NYC
