  • How to read a technical book to remember most of it?

    - by LikeToCode
    There are many technical books that become thinker and thicker and the pressure from the technical society is more and more to read them and remember many concepts described in them. But it's so hard to do it. I have only a few hour a week to read them and when I reach the middle of the book I forgot most of what I've read at the beginning, because lots of time passed. If I go back, I'll just re-read the same stuff over and over, never going past 50% of the book. So, even after I finished reading a thick tech book I forgot most of it. How do you remember all that stuff? I had a talk in my University on how to do it. They advised to use some cards with basic info so that you can remember the details when you look at it. Do you use such cards or do you have other ideas how to do it?

  • How to make technical training session useful and successful for trainee?

    - by metal-gear-solid
    Are these suggestions good to give for a successful training session? Practice time should be always given immediate after technical training? usually after receiving any technical session about any new thing we do routine work. If we don't do practice just after training, later when we do any work related to that training then we feel we need training again. So if we are getting training today and will not use it for some period of time (15 -30 -60 days) then the training is of no use, as it is at the wrong time. I.e. We will forget many things Any other suggestions which i should give? I'm trainee not trainer. What suggestion should i give to trainer/organizer?

  • File sharing for small, distributed, non-technical, non-profit organization?

    - by mnmldave
    Problem: I've started volunteering for a small non-profit with fewer than five non-technical Windows users who need to share 20-30GB of files (Office documents, images, PDFs, etc.) amongst themselves online. Background: The users are accustomed to a Windows network share on a machine that backed up their data locally. An on-site "disaster" has forced them to work from their homes for awhile and to re-evaluate their file sharing needs (office was located in an old building with obvious electrical issues, etc.). Access to time from volunteers with IT experience seems to be difficult. Demonstrably minimizing energy consumption is a nice-to-have. I'm currently considering Jungle Disk (a Desktop account shared amongst the handful of employees since their TOS and my inquiries to their helpdesk seem to indicate this is permissible). It appears easy-to-use, inexpensive, secure, has backup functionality, and can scale to accomodate more data when needed. I've not used it myself though (have only used Dropbox for personal use) and systems isn't my area of expertise, so am worried I might be jumping on a bandwagon. That said, any suggestions, thoughts or similar experiences would be really appreciated.

  • what web based tool, to allow a non-technical user to manage authorized keys files on a Linux (fedora/centos/ubuntu/debian) server

    - by Tom H
    (Edit: clarification below) We have a number of groups of developers that change frequently, and a security policy to require individual logins to servers using rsa or dsa public keys, which is achieved via the standard method of adding id_dsa.pub to their authorized keys file. I am using chef to sync the user accounts across machines, however our previous method of using webmin to manage the user passwords is not designed for key based auth, and hence is not easy to use for non-technical users. The developers are logging in from the WAN using ssh, they can either provide their own key, or an administrator will send them a private key. The development machines are located in the cloud and we have a single server available to host the master set of accounts. Obviously I could deploy ldap or other centralised authentication system, but that seems a bit over blown when webmin worked well for the simple case. It is easy to achieve synchronised users, groups and passwords across a bunch of low security development boxes using webmin clustered users and groups. However looking at the currently installed webmin it is not so easy to create the authorized keys as it is to create user accounts and passwords. (its possible, but its not easy - some functionality is in the usermin module, or would required some tedious steps) Ideally I'd like a web interface that is pretty much dedicated to creating users and groups, and can generate key pairs on the fly, and can accepted pasted in public keys to add to the users authorized keys file. If the tool sync'ed the users and keys as well, that would be great, but I can use chef to do that part if the accounts are created correctly on the "master" server.

  • What is the Oracle Utilities Application Framework?

    - by Anthony Shorten
    The Oracle Utilities Application Framework is a reusable, scalable and flexible java based framework which allows other products to be built, configured and implemented in a standard way. Note: Even though the Framework is built in java it can be integrated with COBOL based extensions for backward compatibility. When Oracle Utilities Customer Care & Billing was migrated from V1 to V2, it was decided that the technical aspects of that product be separated to allow for reuse and independence from technical issues. The idea was that all the technical aspects would be concentrated in this separate product (i.e. a framework) and allow all products using the framework to concentrate on delivering superior functionality. The product was named the Oracle Utilities Application Framework (oufw is the product code). The technical components are contained in the Oracle Utilities Application Framework which can be summarized as follows: Metadata - The Oracle Utilities Application Framework is responsible for defining and using the metadata to define the runtime behavior of the product. All the metadata definition and management is contained within the Oracle Utilities Application Framework. UI Management - The Oracle Utilities Application Framework is responsible for defining and rendering the pages and responsible for ensuring the pages are in the appropriate format for the locale. Integration - The Oracle Utilities Application Framework is responsible for providing the integration points to the architecture. Refer to the Oracle Utilities Application Framework Integration Overview for more details Tools - The Oracle Utilities Application Framework provides a common set of facilities and tools that can be used across all products. Technology - The Oracle Utilities Application Framework is responsible for all technology standards compliance, platform support and integration. There are a number of products from the Tax and Utilities Global Business Unit as well as from the Financial Services Global Business Unit that are built upon the Oracle Utilities Application Framework. These products require the Oracle Utilities Application Framework to be installed first and then the product itself installed onto the framework to complete the installation process. There are a number of key benefits that the Oracle Utilities Application Framework provides to these products: Common facilities - The Oracle Utilities Application Framework provides a standard set of technical facilities that mean that products can concentrate in the unique aspects of their markets rather than making technical decisions. Common methods of configuration - The Oracle Utilities Application Framework standardizes the technical configuration process for a product. Customers can effectively reuse the configuration process across products. Multi-lingual and Multi-platform - The Oracle Utilities Application Framework allows the products to be offered in more markets and across multiple platforms for maximized flexibility. Common methods of implementation - The Oracle Utilities Application Framework standardizes the technical aspects of a product implementation. Customers can effectively reuse the technical implementation process across products. Quicker adoption of new technologies - As new technologies and standards are identified as being important for the product line, they can be integrated centrally benefiting multiple products. Cross product reuse - As enhancements to the Oracle Utilities Application Framework are identified by a particular product, all products can potentially benefit from the enhancement. Note: Use of the Oracle Utilities Application Framework does not preclude the introduction of product specific technologies or facilities to satisfy market needs. The framework minimizes the need and assists in the quick integration of a new product specific piece of technology (if necessary). The Framework is not available as a product itself and is bundled with Tax and Utilities Global Business Unit prodicts. At the present time the following products are on the Framework: Oracle Utilities Customer Care And Billing (V2 and above) Oracle Enterprise Taxation Management (V2 and above) Oracle Utilities Business Intelligence (V2 and above) Oracle Utilities Mobile Workforice Management (V2 and above)

  • I've got two technical degrees but little in the way of experience. How do I get into programming? [closed]

    - by Neonfirelights
    I'm looking for a job, I want to break into programming. I'm looking for the right sort of role and the right place to look for it; I would really appreciate input from someone with industry experience. I've got an excellent academic record: BSc Physics (2:1), MSc Computer Graphics, Vision and Imaging (expecting Merit) from two world ranking universities. I have advanced technical knowledge of C/C++ and Matlab and experience working with C# and VB.NET. Unfortunately I don't have much in the way of commercial experience; unlike a lot of people I know my under-graduate didn't come with a sandwich placement. Where can I go to break into the software industry?

  • Technical/Programming/Non-SEO Pros and Cons of WWW or no-WWW?

    - by Ingenutrix
    What are technical/programming/non-SEO pros and cons of www or no-www, for domains as well as sub-domains? From Jeff Atwood's twitter at http://twitter.com/codinghorror/status/1637428313 : "sort of regretting the no-www choice because it causes full cookie submission to ALL subdomains. :(" What does this mean? Is there a blog post or article detailing this? What other specific issues and their reasons should be considered for www. vs no-www. Update: On searching for more info on this topic, I found following helpful ( in addition to Laurence Gonsalves answer ) : Dropping the WWW Prefix Impact on search results: Jivlain's and Isaac Lin's comments Use Cookie-free Domains for Components on StackOverflow : Should I default my website to www.foo or not? on StackOverflow : When should one use a ‘www’ subdomain?

  • What's the proper technical term for "high ascii" characters?

    - by moodforaday
    What is the technically correct way of referring to "high ascii" or "extended ascii" characters? I don't just mean the range of 128-255, but any character beyond the 0-127 scope. Often they're called diacritics, accented letters, sometimes casually referred to as "national" or non-English characters, but these names are either imprecise or they cover only a subset of the possible characters. What correct, precise term that will programmers immediately recognize? And what would be the best English term to use when speaking to a non-technical audience?

  • Is there a technical way to speed up a general program above current PC speed limit?

    - by Maksee
    Let's imagine I developed a Windows console application implementing some algorithm calculating something. Let's say it doesn't use any threads, just straightforward linear approach with ifs, loops and so on. Is there any technical way to make if run it 100x times faster than on the most advanced current PC? For example one of the way would be to run it on a super computer that emulates i386 faster than any of the existing PCs. But in this case the question what computer and does it really have ability to emulate Windows. In other words, is there real examples of such approach? Although in general it looks useless, but if there is a way, one could develop some program on his general home computer and pay for running it much faster on some other hardware. I suppose that this question could be asked on superuser.com, but since there are possible specific with such things as assembler instructions or threads, I thought that stackoverflow.com is better

  • How to insert an n:m-relationship with technical primary keys generated by a sequence?

    - by bitschnau
    Let's say I have two tables with several fields and in every table there is a primary key which is a technical id generated by a database sequence: table1 table2 ------------- ------------- field11 <pk> field21 <pk> field12 field22 field11 and field21 are generated by sequences. Also there is a n:m-relationship between table1 und table2, designed in table3: table3 ------------- field11 <fk> field21 <fk> The ids in table1 und table2 are generated during the insert statement: INSERT INTO table1 VALUES (table1_seq1.NEXTVAL, ... INSERT INTO table2 VALUES (table2_seq1.NEXTVAL, ... Therefore I don't know the primary key of the added row in the data-access-layer of my program, because the generation of the pk happens completely in the database. What's the best practice to update table3 now? How can I gain access to the primary key of the rows I just inserted?

    - by Ken Lovely, MCSE, MCDBA, MCTS
    Are you ready to connect with the local tech community for a good cause? GiveCamp needs your support. For one weekend in June, we’ll take on the technology wish lists of 20 non-profit organizations, and we’re looking for about 100 volunteers, both technical and non-technical, to help us do it. A typical GiveCamp draws 75 to 100 volunteers. Individuals can work with their colleagues in company teams, or they can opt to be matched with fellow volunteers who have complementary skill sets. Everyone is welcome to head home for the evenings – but there are always the diehards who work from Friday kickoff straight through Sunday afternoon. Food and drinks, especially of the caffeinated variety, are provided, along with game systems for breaks. Technical volunteers We're looking for graphic or UX designers, developers with .NET/Java/LAMP/Open Source/CMS experience, project managers, system/network administrators, DBAs, and non-profit technical consultants and web strategists. Non-technical volunteers Beyond the technology, there are many other aspects that make GiveCamp a success. We need non-technical volunteers to run errands, help with setting up and cleaning up, and everything in between. Whether you can offer a couple hours of your time or join GiveCamp for a couple days, your support is needed Sign up at; http://www.eventbrite.com/event/650615007 Feel free to contact me or Dani Diaz of Microsoft for more information

  • Could somebody give me a high-level technical overview of WSGI details behind the scenes vs other we

    - by orokusaki
    Firstly: I understand what WSGI is and how to use it I understand what "other" methods (Apache mod-python, fcgi, et al) are, and how to use them I understand their practical differences What I don't understand is how each of the various "other" methods work compared to something like UWSGI, behind the scenes. Does your server (Nginx, etc) route the request to your WSGI application and UWSGI creates a new Python interpreter for each request routed to it? How much different is is from the other more traditional / monkey patched methods is WSGI (aside from the different, easier Python interface that WSGI offers)? What light bulb moment am I missing?

  • What technical skills needed for algorithmic trading, HFT, etc?

    - by alchemical
    I'm interested in getting into developing trading systems, black box, HFT, etc. My primary experience is with C# and .Net (7 years). I've also done some sockets programming. I have some experience in finance working on analysis applications (2 years). My goal is to move into developing automated trading systems for a hedge fund, bank, etc. Is there any way to learn the skills needed for this without somehow getting the job first? I've looked at the open source tradelink, IB interactive brokerage, etc. I'm playing around with this framework, and may hook it up and do some paper trading. However, I'm not sure if this has much relationship with how a well-funded entity would be conducting a high-level automated trading operation. I.e. would the tools and frameworks they prefer be a totally different skill-set? Also wondering if I need to learn C++ and/or Java for these types of apps.

    - by Paul D. Waite
    When putting a favicon on your site, you can apparently use an animated gif, just by changing the gif file’s extension to .ico. http://www.k-director.com/blog/how-to-add-an-animated-faviconico/ Have you encountered any problems doing this? (Aside from users being driven mad by some stupid little blinking favicon.) Have you seen a browser get confused by a gif file with a .ico extension?

  • What technical/legal responsibilities do I have when hosting images uploaded by others?

    - by Ferdy
    You may argue that this question has a legal flavor to it, and that would be correct. Still, it is also a question from a developer's perspective that may help others. I'm building an image community web site/application. Users can upload images. During upload, users have to select the license (copyrighted, attribution non-commercial or public domain). No matter which license they choose, it is just a piece of data. No matter the license, all users can view all images and also download all images, as you normally do on websites. My question is: what responsibility do I have as a "platform" to comply with these licenses? Do I need to actively prevent certain actions on these images, and into what extend? Is displaying the license enough to be legally safe? What if one of my users uploads images for which he has no license? Is it enough to just implement a "report this" feature?
