• Where To Begin To Make A Website

  - by lolyoshi

  I'm a newbie in web programming. I haven't done anything that relates to website before. Now, my new task is creating a website using Java, Jsp, HTML, CSS, mySQL, Apache and Spring Framework (MVC model). I want to know what I should research if I want my website has the function as post entries, comment entries, delete entries, edit entries, etc as a forum? Which I need to know beside above things? I don't know how to update my website automatically when there're changes in website as the top view products, the best products. I don't think I'll input or change them manually. So, which tools or language can support that? Thank for advance

• Learning about security and finding exploits

  - by Jayraj

  First things first: I have absolutely no interest in learning how to crack systems for personal enrichment, hurting other people or doing anything remotely malicious. I understand the basis of many exploits (XSS, SQL injection, use after free etc.), though I've never performed any myself. I even have some idea about how to guard web applications from common exploits (like the aforementioned XSS and SQL injection) Reading this question about the Internet Explorer zero-day vulnerability from the Security SE piqued my curiosity and made me wonder: how did someone even find out about this exploit? What tools did they use? How did they know what to look for? I'm wary about visiting hacker dens online for fear of getting my own system infected (the Defcon stories make me paranoid). So what's a good, safe place to start learning?

• restoring grub when Windows 7 MBR lost it

  - by Trent Hall

  My dual boot desktop was running only Windows 7 until it crashed on a windows update. Couldn't get it started again even after all the usual things that might fix it, so I installed Ubuntu 12.04, which has worked very well. unfortunately Carbonite doesn't run on Linux yet, and so I called Microsoft support to see if we could be Windows 7 up and running. Their attempts to get Windows 7 running resulted in writing a new MBR for windows, which failed and also somehow caused the loss of ability to boot into Ubuntu also. How can I get back to Ubuntu? I don't want to lose my settings in Ubuntu. Thanks... Trent

• What are the 'must know' GDB commands?

  - by Chris Smith

  I'm starting to get the hang of GDB, but everything still feels much slower than when debugging in Eclipse or Visual Studio. Are there any GDB commands you find particularly useful/productive? My life became dramatically better when I discovered: list - Display source code near the current instruction But that is still pretty basic. (And unnecessary when running GDB from Emacs.) Is there any way to do things like setup a watch window? (Print and update the result of an expression every time execution stops.)

• Visual Studio 2010: Custom Start Page

  - by Steve Clements

  As Visual Studio 2010 IDE has been mostly written in WPF, extending the start page has become pretty darn easy and I for one find this quite interesting as I always open with the start page and the more customisation I can have the better! There are a few things you will need to install first to get going Visual Studio 2010 SDK Start page project template, which you can either get from the New Project dialog, in the online gallery section in VS or download from here   I was going to write a blog post on how to create a custom start page, but decided that msdn have done such a good job I was pretty much wasting my time, so take a look here, it has in detail everything you need to know to get it done! :) Technorati Tags: Visual Studio 2010,Custom Start Pages

• Resources for 2D rendering using OpenGL?

  - by nightcracker

  I noticed that there is quite some difference between 3D and 2D rendering using OpenGL, the techniques are different - pixel-perfect placing is a lot more desirable, among other things. Are there any good (complete) references on using OpenGL for rendering 2D graphics? There are quite a few "tutorials" around on the net that help you open a window, set up a half-decent environment and draw a sprite, but no real good information on rotation, blending, lightning, drawing order, using the z-buffer, particles, "complex" primitives (circles, stars, cross symbols), ensuring pixel-perfect rendering, instancing and many other staple 2D effects/techniques. Any books, great blogs, anything? Any particular awesome libraries to read?

• GWB | Captchas For Everyone

  - by Geekswithblogs Administrator

  We have been getting hit very hard with comment spam as of late. As mentioned in the last post, this is something we typically deal with on a regular basis for the past 6 years, but some weeks are like this week where it is just crazy. Because of the way things are right now, I have disabled the ability to toggle on or off the CAPTCHA controls for comments. I know some bloggers are going to get mad, but we need to see if the lack of CAPTCHA on some blogs is the key cause of SPAM or if they are manually entering the data and filling in the CAPTCHA. I will report back on what we are seeing, but for a few weeks we are just going to require CAPTCHA controls on comments.This has been a public service announcement for Geekswithblogs.net :D Related Tags:

• Writing low latency Java

  - by user997112

  Are there any Java-specific techniques (things which wouldnt apply to C++) for writing low latency code, in Java? I often see Java low latency roles and they ask for experience writing low latency Java- which sometimes seems a little bit of an oxymoron. The only think I could think of is experience with JNI, outsourcing I/O calls to native code. Also possibly using the disruptor pattern, but thats not an actual technology. Are there any Java specific tips for writing low latency code? I am aware there is a Real Time Java Spec, but I have been warned real-time is not the same as low latency....

• Visual Studio 2010: Fun with extensions

  - by BizTalk Visionary

  One of the powerful things that has come into Visual Studio over the last few years has been joy of extensions. With 2010 there seems to be even more!! Of course teaching old dogs like myself new tricks always takes time but interestingly enough some of the rules I learnt early in my working life over 30 years ago still hold true!! A derivation of one that was knocked into during my engineering apprenticeship and associated exams was RTFQ! Read the ‘flippin’ question. (I replaced the original ‘F’ with a more palatable version here!). Today I forgot that rule and didn’t RTFI (I being instructions) and spent a fruitless hour wondering why my Entity Framework POCO generator never appeared in the new project template list when I wanted to add it!! It was simple of course – I had only installed the Entity Framework POCO generator for web sites and not building a web project meant it would never appear!!! A quick look again I found the ‘other’ extension that supported my project type! So RTFI!!

• Ceská obchodní banka, a.s. Upgrades to Oracle Database 11g On Time, On Budget and without Disrupting Business Operations

  - by jgelhaus

  You want the new features of the latest release, but upgrading a database is one of those things DBAs can "lose sleep" over.  Ceská obchodní banka, a.s."CSOB" needed to upgrade its production systems in the Czech Republic and Slovakia that supported 90 key applications for its retail, corporate, internet, and ATM services from Oracle Database 9i to Oracle Database 11g with simultaneous migration from Alpha processors/OpenVMS-based hardware to a Power7, AIX system. Oracle Consulting helped to complete the upgrade within schedule and budget, while meeting tight restrictions on downtime. Knowledge transfer by Oracle Consulting to the bank’s IT team has improved self-sufficiency in support and maintenance while the technical and advisory services of Oracle Consulting Expert Services continue to optimize performance and availability while lowering cost of ownership. Read how CSOB maximized the value of its investment in Oracle Database technology with an upgrade to Oracle Database 11g.

NOTE I do not need those lenghty books that discuss loops and such I already have experience programming with java and C#.

• Resources on how to relate structured and semi- / un-structured information

  - by Fritz Meissner

  I don't have a great background in information organisation / retrieval, but I know of a few ways of dealing with the problem. For structured information, it's possible to go OOish - everything "has-a" or "has-many" something else, and you navigate the graph to find relationships between things. For unstructured information, you have techniques like text search and tagging. What resources - articles or books - are there that summarise the CS theory behind these techniques or could introduce me to others? I'm developing a system that needs to handle capture and retrieval of information that ranges from necessarily unstructured (advice about X) to structured (list of Xs that relate to Ys) to a combination (Ys that relate to the advice about X) and I'd like to get some insight into how to do it properly.

• How to reset settings when Unity won't finish booting?

  - by Emre

  I have a new 12.04 installation and I messed things up after trying to move /home to an NTFS partition, which I later learned was a bad idea. I removed references to the NTFS partition on fstab and created new users on the ext4 / partition. Now I can't get Unity to start up properly for any user. I get the GUI with only three Launch icons (none of which are clickable) and no bar at the top. The keyboard seems to the nonfunctional after I enter my credentials. The interesting thing is that I can boot when I go through recovery mode and select resume. I wonder whether I am creating the new users properly. What is the correct protocol for doing so in order to ensure that they can run Unity?

• Methods of Geotargeting and optimising for location

  - by Switchfire

  This is somewhat an SEO question and somewhat a general web developer question. Our company website is pretty awful, I'm currently redesigning the new one, the problem is they have a directory called regions, which contains page for around 200 different locations around the country, all stuffed to the brim with keywords and useless things. Some of these pages work and the traffic's good enough to keep a few of them. Apart from creating a page for everyone again, is there another way of targeting all these locations without having to create a new page for each or is the a more dynamic way to do it? Any ideas or suggestions?

• How can I select an appropriate licensing/obfuscation system for .NET?

  - by Adam

  I saw someone suggesting .NET Reactor once as a good obfuscator. I went to their website to check it out and saw they have a product called IntelliLock which is advertised as a pretty robust licensing system which has code protection/obfuscation built in. With that said, I tried to contact them and ask them a few questions regarding the product, but have not had any response. This is kind of a red flag for me. However, it seems like there is some user base for this product whom are satisfied. What .NET licensing system(s) with .NET code protection/obfuscation are you using? What are its pros & cons that you have encountered? Are there things I should be looking for or looking to avoid when evaluating these systems?

• Calendar like tool for managing multiple clients simultaneously?

  - by Yuji Tomita

  I've tried several systems to keep my clients requests / work organized, but somehow they still fall through the cracks. I don't like the idea of a bug tracker-like site for every client (I would not check them all). Ideally, it's all in one page but separated by client. What systems do you guys use? I'm about to just use a spreadsheet with columns for clients. Just curious if there's something better out there :) I've seen smartsheet in action which is basically a really nice spreadsheet that shows bars of time between things that are due. This looks promising.

• How can one manage thousands of IF...THEN...ELSE rules?

  - by David

  I am considering building an application, which, at its core, would consist of thousands of if...then...else statements. The purpose of the application is to be able to predict how cows move around in any landscape. They are affected by things like the sun, wind, food source, sudden events etc. How can such an application be managed? I imagine that after a few hundred IF-statements, it would be as good as unpredictable how the program would react and debugging what lead to a certain reaction would mean that one would have to traverse the whole IF-statement tree every time. I have read a bit about rules engines, but I do not see how they would get around this complexity.

• Ways of Gathering Event Information From the Internet

  - by Ciwan

  What are the best ways of gathering information on events (any type) from the internet ? Keeping in mind that different websites will present information in different ways. I was thinking 'smart' web crawlers, but that can turn out to be extremely challenging, simply because of the hugely varied ways that different sites present their information. Then I was thinking of sifting through the official twitter feeds of organisations, people with knowledge of events .. etc and look for the event hash tag, grab the tweet and dissect it to grab the relevant information about the event. Information I am interested in gathering is: Date and Time of Event, Address where Event is being held, and any Celebrities (or any famous people) attending the event (if any). The reason to ask here is my hope that experienced folk will open my eyes to things I've missed, which I am sure I have.

• How can I get shockwave flash to work on Ubuntu 12.04

  - by John Hill

  I've tried most of the things suggested on this site and others so far. It's kind of frustrating because this is a home computer and I mainly use it for browsing the internet and watching YouTube videos. When I try to install something that might fix it, it just downloads a bunch of files and says to extract them or whatever. I'm not sure what to do with the files after I extract them. That's probably the main issue: I don't have a lot of experience working with computers at this level. I'm used to Windows, which seems to make most software installs idiot-proof. Any suggestions are appreciated!!

• Web services, Java EE, Spring, DB integration project ideas - maybe data mining related?

  - by saral jain

  I am a graduate Computer Science student (Data Mining and Machine Learning) and have good exposure to core Java (3 years). I have read up on a bunch of stuff on the following topics: Design patterns, Java EE Web services (SOAP and REST), Spring, and Hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff -- over my free time of course -- to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + SVN, maven). Any good project ideas would be really appreciated. I just want to build this stuff to learn, so I don't really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus as it fits with my research but is absolutely not necessary since this project is more to learn to do large scale software development.

• Can SAML use saleforce login information to log into another system inside a view?

  - by steve

  I want my sales people, whom use salesforce every day, to be able to view orders in a ecommerce system through a dashboard view in salesforce. The ecom is built and sitting on my web server but the sales reps dont like to log into too many things in one day so they are not using what I built them. I read recently that salesforce can use SAML but it was unclear as to what you can do with it. What I'd like, is to make a new dash board view that will open up the ecom inside of salesforce. The ecom uses a login system but if it is inside of saleforce would SAML automatically log into the ecom?

• Software development life cycle in the industry

  - by jiewmeng

  I am taking a module called "Requirements Analysis & Design" in a local university. Common module, I'd say (on software development life cycle (SDLC) and UML). But there is a lot of things I wonder if they are actually (strictly) practiced in the industry. For example, will a domain class diagram, an not anything extra (from design class), be strictly the output from Analysis or Discovery phase? I'm sure many times you will think a bit about the technical implementation too? Else you might end up with a design class diagram later that is very different from the original domain class diagram? I also find it hard to remember what diagrams are from Initiation, Discovery, Design etc etc. Plus these phases vary from SDLC to SDLC, I believe? So I usually will create a diagram when I think will be useful. Is it the wrong way?

• Is there an 'off the shelf' platform for making a new website similar to Elance?

  - by user17747

  I am interested in developing a website that is similar to 'elance' but for a particular vertical. Is there an 'off the shelf' platform you can recommend for getting started with this, or would I need to develop this web service from scratch? When I write 'platform' I am referring to things such as 'shopify' for e-commerce sites, or 'ning' for social websites. I want to create a multi-merchant professional services site. The site would need to support functionality such as: allowing merchants to open and manage their own profile. merchants would accept payments from customers through the site. file transfers between merchants and customers. merchant ratings by customers.
