  • How should I approach learning programming languages?

    - by gcc
    I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter). I have send that question to stackoverflow before when I am at first year. Now, I want to construct webpage to guide fresh students by giving advise of yours and mines.Maybe, you wonder Why I want to construct webpage , I just want help the other student. I am giving a link to that question < http://stackoverflow.com/questions/3389465/how-should-i-study-programming-languagess If you have other advice, feel free. EDIT: This web cite, I think , is constructed to share member's life experience and also I know these experiences is valuable . So I have no right to want your opinion, But I want your opinion / experience even if you think it is not so helpful to other

  • Oracle Buys BigMachines - Adds Leading Configure, Price and Quote (CPQ) Cloud to the Oracle Cloud to Enable Smarter Selling

    - by Richard Lefebvre
    News Facts Oracle today announced that it has entered into an agreement to acquire BigMachines, a leading cloud-based Configure, Price and Quote (CPQ) solution provider. BigMachines’ CPQ Cloud accelerates the conversion of sales opportunities into revenue by automating the sales order process with guided selling, dynamic pricing, and an easy-to-use workflow approval process, accessible anywhere, on any device. Companies that use sales automation technology often rely on manual, cumbersome and disconnected processes to convert opportunities into orders. This creates errors, adds costs, delays revenue, and degrades the customer experience. BigMachines’ CPQ cloud extends sales automation to include the creation of an optimal quote, which enables sales personnel to easily configure and price complex products, select the best options, promotions and deal terms, and include up sell and renewals, all using automated workflows. In combination with Oracle’s enterprise-grade cloud solutions, including Marketing, Sales, Social, Commerce and Service Clouds, Oracle and BigMachines will create an end-to-end smarter selling cloud solution so sales personnel are more productive, customers are more satisfied, and companies grow revenue faster. More information on this announcement can be found at http://www.oracle.com/bigmachines Supporting Quotes “The fundamental goals of smarter selling are to provide sales teams with the information, access, and insights they need to maximize revenue opportunities and execute on all phases of the sales cycle,” said Thomas Kurian, Executive Vice President, Oracle Development. “By adding BigMachines’ CPQ Cloud to the Oracle Cloud, companies will be able to drive more revenue and increase customer satisfaction with a seamlessly integrated process across marketing and sales, pricing and quoting, and fulfillment and service.” “BigMachines has developed leading CPQ solutions that serve companies of all sizes across multiple industries,” said David Bonnette, BigMachines’ CEO. “Together with Oracle, we expect to provide a complete cloud solution to manage sales processes and deliver exceptional customer experiences.” Supporting Resources About Oracle and BigMachines General Presentation Customer and Partner Letter FAQ

  • ArchBeat Link-o-Rama for November 6, 2012

    - by Bob Rhubart
    OAM/OVD JVM Tuning | @FusionSecExpert Vinay from the Oracle Fusion Middleware Architecture Group (the infamous A-Team) shares a process for analyzing and improving performance in Oracle Virtual Directory and Oracle Access Manager. Architects Matter: Making sense of the people who make sense of enterprise IT Why do architects matter? Oracle Enterprise Architect Eric Stephens suggests that you ask yourself that question the next time you take the elevator to the Oracle offices on the 45th floor of the Willis Tower in Chicago, Illinois (or any other skyscraper, for that matter). If you had to take the stairs to get to those offices, who would you blame? "You get the picture," he says.

  • Should a software developer get a yearly equipment budget?

    - by CrazyDart
    I am looking at a new position with a new company. I have talked to some people in the past (in general, not at this company) that they had been given a yearly budget to buy new computer stuff to keep up to date. Now why I feel this question is worth asking here is that Joel comes right out and says an employer should pay for the best equipment money can buy... within reason of course. From The Joel Test: 12 Steps to Better Code 9. Do you use the best tools money can buy? Writing code in a compiled language is one of the last things that still can't be done instantly on a garden variety home computer... Top notch development teams don't torture their programmers. Even minor frustrations caused by using underpowered tools add up, making programmers grumpy and unhappy. And a grumpy programmer is an unproductive programmer... Does anyone know if the industry has such a standard to offer an allowance or budget? I have never worked for a company like this, but I am thinking I should toss this in the ring for negotiations. Seems reasonable. How do bigger companies like MS, Google, and Apple handle this? If you say yes, give a range... I have been told numbers from $5k to $10k. Seems high to me, but hey I would gladly take it.

  • I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS?

    - by user2567
    I try to understand the benefits of distributed version control system (DVCS). I found Subversion Re-education and this article by Martin Fowler very useful. Mercurial and others DVCS promote a new way of working on code with changesets and local commits. It prevents from merging hell and other collaboration issues We are not affected by this as I practice continuous integration and working alone in a private branch is not an option, unless we are experimenting. We use a branch for every major version, in which we fix bugs merged from the trunk. Mercurial allows you to have lieutenants I understand this can be useful for very large projects like Linux, but I don't see the value in small and highly collaborative teams (5 to 7 people). Mercurial is faster, takes less disk space and full local copy allows faster logs & diffs operations. I'm not concerned by this either, as I didn't notice speed or space problems with SVN even with very large projects I'm working on. I'm seeking for your personal experiences and/or opinions from former SVN geeks. Especially regarding the changesets concept and overall performance boost you measured. UPDATE (12th Jan): I'm now convinced that it worth a try. UPDATE (12th Jun): I kissed Mercurial and I liked it. The taste of his cherry local commits. I kissed Mercurial just to try it. I hope my SVN Server don't mind it. It felt so wrong. It felt so right. Don't mean I'm in love tonight. FINAL UPDATE (29th Jul): I had the privilege to review Eric Sink's next book called Version Control by Example. He finished to convince me. I'll go for Mercurial.

  • TechEd 2012: Fast SQL Server

    - by Tim Murphy
    While I spend a certain amount of my time creating databases (coding around SQL Server and setup a server when I have to) it isn’t my bread and butter.  Since I have run into a number of time that SQL Server needed to be tuned I figured I would step out of my comfort zone and see what I can learn. Brent Ozar packed a mountain of information into his session on making SQL Server faster.  I’m not sure how he found time to hit all of his points since he was allowing the audience abuse him on Twitter instead of asking questions, but he managed it.  I also questioned his sanity since he appeared to be using a fruit laptop. He had my attention though when he stated that he had given up on telling people to not use “select *”. He posited that it could be fixed with hardware by caching the data in memory.  He continued by cautioning that having too many indexes could defeat this approach.  His logic was sound if not always practical, but it was a good place to start when determining the trade-offs you need to balance.  He was moving pretty fast, but I believe he was prescribing this solution predominately for OLTP database prior to moving on to data warehouse solutions. Much of the advice he gave for data warehouses is contained in the Microsoft Fast Track guidance so I won’t rehash it here.  To summarize the solution seems to be the proper balance memory, disk access speed and the speed of the pipes that get the data from storage to the CPU.  It appears to be sound guidance and the session gave enough information that going forward we should be able to find the details needed easily.  Just what the doctor ordered. del.icio.us Tags: SQL Server,TechEd,TechEd 2012,Database,Performance Tuning

  • Blatant copyright theft

    - by Tom Gullen
    Found a user on the forum trying to solicit business for his website, a good user reported it and I checked the website out. Firstly and most dangerously it's attempting to sell our original software, which is open source. Our open source software is around 15mb big and he's serving a 50mb download and trying to sell it for $20. He's also stolen our CSS/images/site design in general which is all custom built. I attempted to open reasonable discussion with him, and he responded promptly saying he would remove offending materials if he could just have 3 days to sort it out which I accepted. I'm not sure what his plan was because everything on that site is offending material. Anyway he messaged back saying the site was offline, and it was, but it went back online shortly afterwards. It's pretty sickening that someone is selling open source work as their own, (the site about us page references him as the sole developer etc etc, it's unbelievable to read it). I want to shut it down, what are my options? I'm going to contact his domain registrar, web host, and Paypal (that's how he's selling the program). Any other ideas?

  • New: Online NetBeans 8 Crash Course

    - by Geertjan
    On Twitter today I came across an announcement for a brand new on-line course in NetBeans 8. Since NetBeans 8 has been released during the past few months, the course is really very new. Go here to get there directly: https://www.video2brain.com/de/videotraining/netbeans-ide-8-0-crashkurs Here's the general idea. As you can see, the course is in German. With my basic understanding of German, I've had no problem in following the course. The trainer speaks clearly and slowly and everything is very well structured. The course covers all the basics of NetBeans IDE. From getting set up to using all the key features. The quality of the videos is great and the content is clear and informative. Once you've bought the course, all the lessons are unlocked. As you can see, they're all quite short and there's really a lot of content, didn't all fit into the screenshot: Quite some work must have gone into this. Here's one of the free lessons in the course, to give an idea of what you'll get: https://www.video2brain.com/de/tutorial/texte-internationalisieren This one is also free: https://www.video2brain.com/de/tutorial/eclipse-projekt-importieren I highly recommend this course especially if you're switching, or thinking about switching, from a different IDE and want to get a thorough overview of all the features that NetBeans IDE provides. Everything in the course is done within NetBeans, which means no slides, just code. You get to see the workflow of all the standard tasks and, for these purposes, the course does a really great job.

  • Looking for job advice [closed]

    - by EntryLevelJavaDeveloper
    I am a software developer for a government agency in DC, and I have recently completed one year of employment. I am generally dissatisfied with my experiences here. I do not want to gripe too much, but I do not spend a lot of time doing actual development on projects. I am asked to do everything under the sun: write requirements, review specs, test, attend random meetings, but actual coding makes up a small fraction of my time. The coding itself is fairly straightforward and simple so it feels like I am not growing from my experiences. I am not tasked with more challenging work, and I find the experiences are not rewarding. If I had a stronger resume/more work experience, I'd leave the position immediately but combined with the present economy, I am hesitant to leave. I have several questions: Does anybody have experiences like this? How did you make the most of it? I am currently doing some side projects, making simple webpages for people, but aside from that, and open source projects, what other things are out there? What are general benchmarks for a developer after one year of professional experience? What should I be expected to know/do? I am outsider (coming from a math/science background) so I do not know what exactly I should know/do. Is it possible to obtain a mentorship with a mid/senior developer to learn? If so, how can I go about making contacts in the DC area?

  • Storage of leftover values in a situation of having to round down

    - by jt0dd
    I'm writing an app (client and server side) where the number of sales required by each employee must be kept track of in round-number form. Each month, the employees are required to sell a certain number, and this app needs to keep track of how many sales must be made for each 12 hour interval during the work week. Because I have to round the values down to a whole number, I must keep track of leftovers in the rounding process and ensure that they are always carried over. My method must ensure the storage of the leftover value even when client and server side crash, restart, close, etc. Right now, I'm working on doing this by storing the leftovers in a field in the user's account row in the database each time a value is rounded, reading the stored value, removing any portion that is used (when a whole number is reached, most of the leftover is used up), and storing the new value. This practice seems weird because while the leftovers are calculated on the client side, it's the same number for each employee, and every employee using the app is storing a copy of the same leftover data. Alternatively, I could have all clients store the data at once into the same data field on a general table, but this is just as weird. Is there a better way that this can be handled or is my method correct?

  • How to identify web development benchmarking questions? [closed]

    - by GenericJam
    I am in my final year of college and I have to put forward some sort of thesis for my final year project. The project is a web based attendance system that I am building for the college. I have it about 70% complete in Java. After completing it in Java, the plan is for me to rewrite the server bit in Erlang and then release the bitter rivals in a head to head cage match. The idea being that there is some sort of grounds for comparison. There are a few hurdles along the way, such as me learning Erlang. I understand that a performance comparison like this isn't strictly scientific as there are many factors such as the programmer (myself); the hardware it runs on; etc... but it is meant to be a reasonable comparison of the merits of using Java vs. Erlang for web development. I need help in identifying what the relevant questions are that my project could address. Even though the project scope is fixed, I am trying to shoehorn in some worthwhile scientific inquiries.

  • Impact of Server Failure on Coherence Request Processing

    - by jpurdy
    Requests against a given cache server may be temporarily blocked for several seconds following the failure of other cluster members. This may cause issues for applications that can not tolerate multi-second response times even during failover processing (ignoring for the moment that in practice there are a variety of issues that make such absolute guarantees challenging even when there are no server failures). In general, Coherence is designed around the principle that failures in one member should not affect the rest of the cluster if at all possible. However, it's obvious that if that failed member was managing a piece of state that another member depends on, the second member will need to wait until a new member assumes responsibility for managing that state. This transfer of responsibility is (as of Coherence 3.7) performed by the primary service thread for each cache service. The finest possible granularity for transferring responsibility is a single partition. So the question becomes how to minimize the time spent processing each partition. Here are some optimizations that may reduce this period: Reduce the size of each partition (by increasing the partition count) Increase the number of JVMs across the cluster (increasing the total number of primary service threads) Increase the number of CPUs across the cluster (making sure that each JVM has a CPU core when needed) Re-evaluate the set of configured indexes (as these will need to be rebuilt when a partition moves) Make sure that the backing map is as fast as possible (in most cases this means running on-heap) Make sure that the cluster is running on hardware with fast CPU cores (since the partition processing is single-threaded) As always, proper testing is required to make sure that configuration changes have the desired effect (and also to quantify that effect).

  • Is this the correct approach to an OOP design structure in php?

    - by Silver89
    I'm converting a procedural based site to an OOP design to allow more easily manageable code in the future and so far have created the following structure: /classes /templates index.php With these classes: ConnectDB Games System User User -Moderator User -Administrator In the index.php file I have code that detects if any $_GET values are posted to determine on which page content to build (it's early so there's only one example and no default): function __autoload($className) { require "classes/".strtolower($className).".class.php"; } $db = new Connect; $db->connect(); $user = new User(); if(isset($_GET['gameId'])) { System::buildGame($gameId); } This then runs the BuildGame function in the system class which looks like the following and then uses gets in the Game Class to return values, such as $game->getTitle() in the template file template/play.php: function buildGame($gameId){ $game = new Game($gameId); $game->setRatio(900, 600); require 'templates/play.php'; } I also have .htaccess so that actual game page url works instead of passing the parameters to index.php Are there any major errors of how I'm setting this up or do I have the general idea of OOP correct?

  • How Do Computers Work? [closed]

    - by Rob P.
    This is almost embarrassing ask...I have a degree in Computer Science (and a second one in progress). I've worked as a full-time .NET Developer for nearly five years. I generally seem competent at what I do. But I Don't Know How Computers Work! Please, bare with me for a second. A quick Google of 'How a Computer Works' will yield lots and lots of results, but I struggled to find one that really answered what I'm looking for. I realize this is a huge, huge question, so really, if you can just give me some keywords or some direction. I know there are components....the power supply, the motherboard, ram, CPU, etc...and I get the 'general idea' of what they do. But I really don't understand how you go from a line of code like Console.Readline() in .NET (or Java or C++) and have it actually do stuff. Sure, I'm vaguely aware of MSIL (in the case of .NET), and that some magic happens with the JIT compiler and it turns into native code (I think). I'm told Java is similar, and C++ cuts out the middle step. I've done some mainframe assembly, it was a few years back now. I remember there were some instructions and some CPU registers, and I wrote code....and then some magic happened....and my program would work (or crash). From what I understand, an 'Emulator' would simulate what happens when you call an instruction and it would update the CPU registers; but what makes those instructions work the way they do? Does this turn into an Electronics question and not a 'Computer' question? I'm guessing there isn't any practical reason for me to understand this, but I feel like I should be able to. (Yes, this is what happens when you spend a day with a small child. It takes them about 10 minutes and five iterations of asking 'Why?' for you to realize how much you don't know)

  • Hello!

    - by barryoreilly
    After many months of deliberating I have finally gotten around to starting this blog! The reason for doing this is the large number of half finished articles lying around on my hard disk, unpublished and unloved. These articles have been of huge benefit to me, and have been written in an attempt to consolidate my own thinking, in order to help me structure my thoughts and ideas as I have tried to digest new ideas and understand abstract theories. It is my hope that by tidying up these articles and publishing them here that I can continue this learning process by getting feedback on the ideas from within the developer community. i have worked with .NET for 8 years now, and have worked with ASP.NET, SQL Server, Windows programming as well as general network administration. Since 2004 my focus has been on integration, web services, and more often than not Biztalk Server. The last two years have seen me focus on SOA and WCF, and the Managed Services Engine, so this is probably where the main focus of the blog will to start with, but there are so many fun things to play with these days that i have no idea where it will end up.....   Barry

  • Non-dynamic CMS [closed]

    - by user20457
    Some of the web sites I visit every day (news, sports, etc..), although the content changes very often (several times per day), the URLs always have .html extension, what makes me thing that the content has been generated once, and then published as a static page, rather than generated in every call, or even cached in memory. For example, the fictitious site "mysports.com" have a "futbol.html" page, and then yesterday Messi gets injured and they have another thing to put in that page, then I presume they post the new item in their CMS system, and automatically a publishing action is triggered aftewards that recreates "futbol.html" in a CDN with the new item and probably discard the oldest one. Then the ETag changes and clients will get the new page if they try to access it. (the site is fictitious but this is what I believe happened yesterday in the sports site I read) This would fit in the CQRS approach, and I presume they have a huge performance. I know lots of CMS (WP, Drupal, BlogEngine.net, DNN, etc...), but I have never seen any able of doing this, or at least, I was not aware this feautre. How are called those distributed CMS? Which are the most well known? Cheers.

  • How does Game Salad compare with Cocos2D in terms of 2D game development?

    - by jih
    I want to make some 2d games for iOS. I first come across cocos2d and kobold but then wanted something more graphical for rapid prototyping. I then found Game Maker which doesn't support iOS but is fairly easy to learn and then found Game Salad which supports iOS as well as other platforms. I know this question has been ask before but I want to know in terms of the types of games I want to develop what an learning investment path would be best. The types of games genre I am interest are: Side scrollers Simple games like diamond dash or ninja fruits, shanghai, etc Old fashioned zelda or dragonquest type (nintendo fan here:-) 2d adventure RPG games (real time or turn based) Mystery turn based games like carmen sandiego, wizardry, myst etc. So now the question becomes for me becomes which game development environment should I invest my time in learning. Game Salad or cocos2d? To make that decision I was wondering if experienced game programmers and help with some pointers: It would seem game salad would be great for quickies being graphical but in terms of 2d platform games etc would there be speed/performance/feature penalties? Are there certain 2d games genre of the 4 above that Game salad is better at while certain type cocos2d would be better at?

  • More Tables or More Databases?

    - by BuckWoody
    I got an e-mail from someone that has an interesting situation. He has 15,000 customers, and he asks if he should have a database for their data per customer. Without a LOT more data it’s impossible to say, of course, but there are some general concepts to keep in mind. Whenever you’re segmenting data, it’s all about boundary choices. You have not only boundaries around how big the data will get, but things like how many objects (tables, stored procedures and so on) that will be involved, if there are any cross-sections of data (do they share location or product information) and – very important – what are the security requirements? From the answer to these types of questions, you now have the choice of making multiple tables in a single database, or using multiple databases. A database carries some overhead – it needs a certain amount of memory for locking and so on. But it has a very clean boundary – everything from objects to security can be kept apart. Having multiple users in the same database is possible as well, using things like a Schema. But keeping 15,000 schemas can be challenging as well. My recommendation in complex situations like this is similar to a post on decisions that I did earlier – I lay out the choices on a spreadsheet in rows, and then my requirements at the top in the columns. I  give each choice a number based on how well it meets each requirement. At the end, the highest number wins. And many times it’s a mix – perhaps this person could segment customers into larger regions or districts or products, in a database. Within that database might be multiple schemas for the customers. Of course, he needs to query across all customers, that becomes another requirement. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • ECS with Go - circular imports [migrated]

    - by Andreas
    I'm exploring both Go and Entity-Component-Systems. I understand how ECS works, and I'm trying to replicate what seems to be the go-to document of ECS, namely http://cowboyprogramming.com/2007/01/05/evolve-your-heirachy/ For performance, the document recommends to use static arrays of every component type. That is, not arrays of component interfaces (arrays of pointers). The problem with this in Go is circular imports. I have one package, ecs, which contains the definitions for Entity, Component and System types/interfaces as well as an EntityManager. Another package, ecs/components, contains the various components. Obviously, the ecs/components package depends on ecs. But, to declare arrays of specific components in EntityManager, ecs would depend on ecs/components, therefore creating a circular import. Is there any way of avoiding this? I am aware that normally a high level system should not depend on lower systems. I'm also want to point out that using an array of pointers is probably fast enough for my purposes, but I'm interested in possible workarounds (for future reference) Thank you for your help!

  • What are some best practices for minimizing code?

    - by CrystalBlue
    While maintaining the sites our development team has created, we have come across include files and plugins that have proven to be very useful to more then one part of our applications. Most of these modules have come with two different files, a normal source file and a min file. Seeing that the performance and speed of a page can be increased by minimizing the size of the file, we're looking into doing that to our pages as well. The problem that we run into is a lot of our normal pages (written in ASP classic) is a mix of HTML, ASP, Javascript, CSS, and include files. We have some pages that have their JS both in include files and in the page, depending on if the function is only really used in that page or if it's used in many other pages. For example, we have a common.js and an ajax.js file, both are used in a lot of pages, but not all of them. As well as having some functions in a page that doesn't really make sense to put into one master page. What I have seen a few other people do online is use one master JS file and place all of their javascript into that, minify it, gzip it, and only use that on their production server. Again, this would be great, but I don't know if that fully works for our purposes. What I'm looking for is some direction to go with on this. I'm in favor of taking all of our JS and putting it in one include file, and just having it included in every page that is hit. However, not every page we have needs every bit of JS. So would it be worth the compilation and minifying of the files into one master file and include it everywhere, or would it be better to minify all other files and still include them on a need-to-use basis?
