  • Why Banks or Financial Companies prefer Oracle than other RDBMS for their "Core" systems?

    - by edwin.nathaniel
    I'd like to know why most Banks or Financial companies prefer Oracle than other RDBMS for their core systems (the absolutely minimum features that a Bank must support). I found a few answers that didn't satisfy me. For example: Oracle has more features. But features for what? Can't you implement that in application level if you were not using Oracle? Could someone please describe a bit more technical but still on high-level overview of what the bank needs and how Oracle would solve it and the others can't or don't have the features yet? I came from the web-app (web 2.0) crowd who normally hear news about MySQL, PostgreSQL or even key-value/column-oriented storage solution. I have almost zero knowledge on how Banks or Financial companies operates from technical perspective. Thank you, Ed

  • Agile and code release

    - by ring bearer
    Do you know of any agile process that is created for code releases? One of the main theme of agile is frequent releases and each company/client would have their own test/approval processes that control code releases. Most of the time these slow down the pace of "frequent releases" Currently we have a proprietary tool based workflow. The team who needs a code promotion needs to create a promotion request to one of the final UAT servers. Once this is complete, and once tests are done, certain customers, technical/non-technical managers need to approve, then it goes in to production deploy stage. Meanwhile no sprint planning meeting or anything of that sort. What is the code release process (Which is agile) that has worked for you?

  • Should economics be taught to geeks?

    - by asksuperuser
    When I interview developers for jobs I'm really astonished by their lack of economics consciousness. It seems they think they'll be recruited just for technological fun. When you ask them for technical solutions they would just follow hypes from software editors without consideration for the economics part. I have rejected 80% of candidates just for that kind of reason. I don't know if other recruiters ask economics questions, but as for me that is one of the main criterias. That is why I prefer to enquiry by myself on technical questions because I just don't trust the geeks choice. So did you learn economics at school ? At mine yes and that did serve me.

  • Why is memory management so visible in Java VM?

    - by Emil
    I'm playing around with writing some simple Spring-based web apps and deploying them to Tomcat. Almost immediately, I run into the need to customize the Tomcat's JVM settings with -XX:MaxPermSize (and -Xmx and -Xms); without this, the server easily runs out of PermGen space. Why is this such an issue for Java VMs compared to other garbage collected languages? Comparing counts of "tune X memory usage" for X in Java, Ruby, Perl and Python, shows that Java has easily an order of magnitude more hits in Google than the other languages combined. I'd also be interested in references to technical papers/blog-posts/etc explaining design choices behind JVM GC implementations, across different JVMs or compared to other interpreted language VMs (e.g. comparing Sun or IBM JVM to Parrot). Are there technical reasons why JVM users still have to deal with non-auto-tuning heap/permgen sizes?

  • Would you take a pay-cut to get a higher position?

    - by jonathanconway
    Say you're in a contracting developer role at a bank that pays well and will probably be extended. Then you get offered a permanent role at an IT solution provider as a Senior Developer/Technical Lead. Would you stick with the contracting, or go to the permanent role? The contract role: pays well will probably be extended provides finance industry experience is reasonably challenging, although I don't get much ownership over the projects The permanent role: pays less gives me technical lead/team lead experience- involves a range of websites for different clients, and I get to take ownership of projects much more challenging technically, as I have to "earn my stripes" within the team before I'll be given team lead responsibilities. If you were in this situation, would you take the pay-cut and go with the permanent role? Or would you continue contracting, and not feel like you might have missed out on something really good?

  • What do you tell people your profession is? [closed]

    - by user110296
    My technical title is Member of the Technical Staff, and like you most of you, I design/write code for a living. I can never decide what to answer when someone asks what I do for a living? Software Developer? Software Engineer? [Kernel] Programmer? Computer Scientist? These all seem to have various bad connotations. I guess I like Software Engineer the best, but unfortunately this term has been coopted by people who don't actually code. I made the mistake of taking a 'Software Engineering' class, and realized that I definitely don't want to be associated with people who major in this. Probably this is too subjective, so feel free to community wiki it or whatever, but I think it is a valid question and I would like to hear what others have decided on and their reasoning.

  • some examples for using specific searchalgorithm

    - by Robert
    I could understand the following search algorithms: Constraint Satisfaction with Arc Consistency, Uninformed search A* Search MinMax I would understand the definition and working principles of the above algorithm,but could you please give me some real world examples that the above algorithms will be suitable?My idea would be: For CSP with Arc Consistency,assign students to groups that each group must contain both technical and management students,and no 2 technical students in a same group. Uniformed Search: search for a file under UNIX directoy. A* Search: search a way (staring from home) to go to mulitple stores to buy things then get back home with minimum total travelling time. MinMax:Go or other Chess. Please correct me if I am wrong.

  • How does the Amazon Recommendation feature work?

    - by Rachel
    What technology goes in behind the screens of Amazon recommendation technology? I believe that Amazon recommendation is currently the best in the market, but how do they provide us with such relevant recommendations? Recently, we have been involved with similar recommendation kind of project, but would surely like to know about the in and outs of the Amazon recommendation technology from a technical standpoint. Any inputs would be highly appreciated. Update: This patent explains how personalized recommendations are done but it is not very technical, and so it would be really nice if some insights could be provided. From the comments of Dave, Affinity Analysis forms the basis for such kind of Recommendation Engines. Also here are some good reads on the Topic Demystifying Market Basket Analysis Market Basket Analysis Affinity Analysis Suggested Reading: Data Mining: Concepts and Technique

  • Keeping Computer Science Writing Accessible and Eloquent

    - by Federer
    This question is particularly aimed at descriptions and explanations of what is happening in a computer program, as well as any general advice or approaches for undertaking technical reports in Computer Science at both undergraduate and graduate levels. You see, I am having particular difficulty in the best way to explain what is happening. As in, given any given program from a multi-agent system to a standard webservice, the best and most eloquent way to say exactly what is going on, the logic behind it and it's respective justifications. Should I avoid saying class names? Avoid specifying methods? Keep referring to class variables and any particular references? I'm banging my head against the wall at trying to keep a solid technical foundation and making it accessible to people of all backgrounds. Apologies for the rather vague question. Cheers.

  • Can you Borrow a PDF?

    - by WeNeedAnswers
    What are the legalities of letting someone borrow a book that you have purchased that so happens to be in PDF format with no DRM? I know that I can lend a printed book to someone and this not infringe copyright, but a pdf? I know that the thought police are going to be on my case about "no one here is a legal expert" or the "question can't be answered" or "controversial", But I would like to have the opportunity to at least surface the issue, and allow people to comment. I am not looking for point scoring on this, or even an answer, but as stackoverflow has a rather large technical savvy audience that would appreciate the question I think that it could be the next hurdle that will stop technical progress.

  • Delphi/Pascal training in high school/college/university

    - by Bruce McGee
    Are Delphi/Pascal being taught in any high schools/colleges/universities, particularly in Canada and the US? I was surprised how many schools in the UK are teaching Delphi. Their largest exam board is even dropping PHP/C#/C in 2011 and encouraging Delphi. I also remember that CodeGear was going to provide development tool licenses to Russian schools a couple of years ago. I'd like to know if it's being taught closer to (my) home.

    Hi, I'm thinking of a serious training in j2ee and found there are too many books to choose from. Could you kindly share your insights as a practicing professional in this respect?

  • One Line 'If' or 'For'...

    - by aTory
    Every so often on here I see someone's code and what looks to be a 'one-liner', that being a one line statement that performs in the standard way a traditional 'if' statement or 'for' loop works. I've googled around and can't really find what kind of ones you can perform? Can anyone advise and preferably give some examples? For example, could I do this in one line: example = "example" if "exam" in example: print "yes!" Or: for a in someList: list.append(splitColon.split(a))

    Hi, Is there a sexy way to get a web page with Google Maps (in fullscreen), and just a small div#header on the top and a small div#container on the middle? I had make some research and I had found this example: http://koti.mbnet.fi/ojalesa/exam/index.html ... but this is not exactly what I would like to do. If you have a thin code example of a nice website example, this would help me a lot. Many Thanks.

  • capturing user identity for an online application

    - by Samuel
    We are designing an online application (college admission form) which mandates the user to upload a scanned copy of his photo along with his signature, so that this information can be used to cross verify the applicant when he appears for a exam + personal interview at a later point in time. This entire process requires a scanner for the applicant to scan his photo / signature into an appropriate size. Is there a better way to capture user identity for such purposes as usage of scanner for capturing signature, photo is a painful process.
