• Can I have a computer with 2 physical HDs, & Dual boot option, one for Windows & one for Ubuntu

  - by Frank

  When my HD failed in my old computer with a dual core, I immediately went out and bought a new 6 core PC because I needed it for business and had to have an immediate solution. The old computer was otherwise a good computer. I don't want to spend a $100+ for a new operating system for the old computer because the Windows 7 Professional opperating system for the new computer will only allow one install. So, I decided to look and see if there were any free operating systems and found Ubuntu. I downloaded it and burned a live CD and would like to try it on the old computer. I found a 200 GB HD I can buy for $30 and the seller will format it any way I want. There are also other HDs available at a similar price. What I was thinking I would like to do is buy 2 HDs. Then I can have one formatted for Ubuntu 12.04 and install Windows XP Pro SP1 on the other HD for which I have the original installation CD. Then I would like to have a dual boot option so that when I power up the computer, I can choose whether to use Windows XP or Ubuntu. Is this possible? If so, how would I do it, that is, arrange it so a dual boot option presents itself on power up.

• Monitor offline adwords conversions

  - by Frank Meulenaar

  I'm trying to evaluate the usefulness of Google Adwords for a friend's site. I'm trying to count the number of sales per month, and see how many have found her page because of the Adwords campaign. Her site has an online order system, but she also gets customers that buy just via the email contact and never use the online order system. There aren't many conversions per month (usually only one to three), so I don't want to miss any conversions when I want to gauge the effectiveness of a campaign. Is there a good way to also include those conversions?

• How-To: Run CMSDK against a RAC cluster

  - by frank.closheim

  Using CMSDK in a production environment often requires a robust, reliable and failover enabled repository. When using Oracle Real Application Cluster (RAC) with your CMSDK repository you need to have a specific configuration in place to support such a setup. This post will explain the configuration steps required when running CMSDK 9.0.4.6 with Oracle WebLogic Server (WLS).In the previous CMSDK 9.0.4.2 version a RAC enabled connect string looked like this: (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = rac1)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = rac2)(PORT = 1521))(LOAD_BALANCE = NO)(FAILOVER = ON)(CONNECT_DATA =(SERVICE_NAME = rac)(failover_mode = (type=select)(method=basic)))CMSDK 9.0.4.6 makes use of data sources to connect to the underlying database. These data sources are configured inside your Application Server, such as Oracle WebLogic Server.In Oracle WebLogic Server 10.3.4, a single data source implementation has been introduced to support an RAC cluster. It responds to Fast Application Notification (FAN) events to provide Fast Connection Failover (FCF), Runtime Connection Load-Balancing (RCLB), and RAC instance graceful shutdown. XA affinity is supported at the global transaction Id level. The new feature is called WebLogic Active GridLink for RAC; which is implemented as the GridLink data source within WebLogic Server.This GridLink data source also works with Oracle Single Client Access Name (SCAN). SCAN is a feature used in RAC environments that provides a single name for clients to access any Oracle Database running in a cluster. You can think of SCAN as a cluster alias for databases in the cluster. The benefit is that the client’s connect information does not need to change if you add or remove nodes or databases in the cluster.The CMSDK 9.0.4.6 documentation describes how to create a regular JDBC data source named jdbc/OracleDS. Please refer to the following document which describes in detail how to create a GridLink data source in WLS.

• How much game dev does $x amount of money get you?

  - by Frank

  How much a game costs to make gets asked often and is always answered with it depends or varies on the quality of the game. Well this is basically the same question but is a bit more precise. I'm wonder what quality of game you can make with varying degrees of funds. Lets say 500k, 1m, 2m, 5m, 10m, 15m, and 20m. Let's assume you don't do any of it yourself and it only covers development only... no advertising or manufacturing.

• Azure website that talks to third party services

  - by Andy Frank

  I have website that crawls data from many third party services when user browse to webpage. This can be really slow because I hit third party server and process returned data before showing it to user. I am hosting website on Azure (shared mode). I am thinking to improve my implementation. Here is what I am thinking... Run a service that crawls data from third party services, process it and then store it in database. when user browse to my site, my site pulls data from database and display them to user. But above solution is not clear to me. Should I have normal service or wcf service? If wcf service then should website talk to database or wcf service (that can access data from database)? If normal service then how can I deploy on Azure?

• BigDecimal.floatValue versus Float.valueOf

  - by Frank

  Has anybody ever come across this: System.out.println("value of: " + Float.valueOf("3.0f")); // ok, prints 3.0 System.out.println(new BigDecimal("3.0f").floatValue()); // NumberFormatException I would argue that the lack of consistency here is a bug, where BigDecimal(String) doesn't follow the same spec as Float.valueOf() (I checked the JDK doc). I'm using a library that forces me to go through BigDecimal, but it can happen that I have to send "3.0f" there. Is there a known workaround (BigDecimal is inaccessible in a library).

• Ubuntu 12.04 freezing on startup

  - by Frank

  Have been looking everywhere to find a solution to this problem but have yet to find a solution. I am running 64 bit 12.04 LTS on a AMD C-50 Dual core 6 gigs ram AMD Ratheon HD 6250. The problem I am experiencing is when ubuntu gets to the wallpaper screen it will sometimes freeze soon after the the image appears or shortly there after gnome loads locking up keyboard and mouse. When I try to log in via the console the same thing happens (this is as ubuntu is loading). At the moment the system is set to auto login previously it was set to ask for password but it did the same thing. Switching to from lightdm to gdm did nothing to alleviate the issue. I have never had so many issues with ubuntu I have to say 12.04 is the most buggy version yet.

• Web Form Testing [closed]

  - by Frank G.

  I created a application for a client that is along the lines of a ticket tracking system. I wanted to know if anyone know of software that could beta test the web forms. Well I am looking for something that could automatically populate/fill whatever forms are on the web page with generic data. The purpose of this is to just randomly populate data and see if I get any errors on the page when submitted plus to also see how validation for the form functions. Does anyone know of anything that could do this?

• Collision point of 2 curves in a 3d-room

  - by Frank

  Hello, i am programming a small game for quite some time. We started coding a small FPS-Shooter inside of a project at school to get a bit experience using directX. I dont know why, but i couldnt stop the project and started programming at home aswell. At the moment i am trying to create some small AI. Of cause thats definatlly not easy, but thats my personal goal anyways. The topic could prolly fill multiple books hehe. I've got the walking part of my bots done so far. They walk along a scriped path. I am not working on the "aiming" of the bots. While programming that i hit on some math problem i couldnt solve yet. I hope of your input on this to help me get further. Concepts, ideas and everything else are highly appreciated. Problem: Calculate the position (D3DXVECTOR3) where the curve of the projectile (depends on gravity, speed), hit the curved of the enemys walking path (depends on speed). We assume that the enemy walks in a constant line. Known variables: float projectilSpeed = 2000 m/s //speed of the projectile per second float gravitation = 9.81 m/s^2 //of cause the gravity lol D3DXVECTOR3 targetPosition //position of the target stored in a vector (x,y,z) D3DXVECTOR3 projectilePosition //position of the projectile D3DXVECTOR3 targetSpeed //stores the change of the targets position in the last second Variabledefinition ProjectilePosition at time of collision = ProjectilePos_t TargetPosition at time of collision = TargetPos_t ProjectilePosition at time 0, now = ProjectilePos_0 TargetPosition at time 0, now = TargetPos_0 Time to impact = t Aim-angle = theta My try: Found a formular to calculate "drop" (Drop of the projectile based on the gravity) on Wikipedia: float drop = 0.5f * gravity * t * t The speed of the projectile has a horizontal and a vertical part.. Found a formular for that on wikipedia aswell: ProjectilVelocity.x = projectilSpeed * cos(theta) ProjectilVelocity.y = projectilSpeed * sin(theta) So i would assume this is true for the projectile curve: ProjectilePos_t.x = ProjectilePos_0.x + ProjectileSpeed * t ProjectilePos_t.y = ProjectilePos_0.y + ProjectileSpeed * t + 0.5f * gravity * t * t ProjectilePos_t.z = ProjectilePos_0.z + ProjectileSpeed * t The target walk with a constant speed, so we can determine his curve by this: TargetPos_t = TargetPos_0 + TargetSpeed * D3DXVECTOR3(t, t, t) Now i dont know how to continue. I have to solve it somehow to get a hold on the time to impact somehow. As a basic formular i could use: float time = distanz / projectileSpeed But that wouldnt be truly correct as it would assume a linear "Trajectory". We just find this behaivor when using a rocket. I hope i was able to explain the problem as much as possible. If there are questions left, feel free to ask me! Greets from germany, Frank

• Java remove HTML from String without regular expressions

  Hello, I am trying to remove all HTML elements from a String. Unfortunately, I cannot use regular expressions because I am developing on the Blackberry platform and regular expressions are not yet supported.

• Tough Decisions

  - by Johnm

  There was once a thriving business that employed two Database Administrators, Sam and Jim. Both DBAs were certified, educated and highly talented in their skill sets. During lunch breaks these two DBAs were often found together discussing best practices, troubleshooting techniques and the latest release notes for the upcoming version of SQL Server. They genuinely loved what they did. The maintenance of the first database was the responsibility of Sam. He was the architect of this server's setup and he was very meticulous in its configuration. He regularly monitored the health of the database, validated backup files and regularly adhered to the best practices that were advocated by well respected professionals. He was very proud of the fact that there was never a database that he managed that lost data or performed poorly. The maintenance of the second database was the responsibility of Jim. He too was the architect of this server's setup. At the time that he built this server, his understanding of the finer details of configuration were not as clear as they are today. The server was build on a shoestring budget and with very little time for testing and implementation. Jim often monitored the health of the database; but in more of a reactionary mode due to user complaints of slowness or failed transactions. Deadlocks abounded and the backup files were never validated. One day, the announcement was made that revealed that the business had hit financially hard times. Budgets were being cut, limitation on spending was implemented and the reduction in full-time staff was required. Since having two DBAs was regarded a luxury by many, this meant that either Sam or Jim were about to find themselves out of a job. Sam and Jim's boss, Frank, was faced with a very tough decision. Sam's performance was flawless. His techniques and practices were perfection. The databases he managed were reliable and efficient. His solutions are "by the book". When given a task it is certain that, while it may take a little longer, it will be done right the first time. Jim's techniques and practices were not perfect; but effective and responsive. He made mistakes regularly; but he shows that he learns from them and they often result in innovative solutions. When given a task it is certain that, while the results may require some tweaking, it will be done on time and under budget. You are Frank's best friend. He approaches you and presents this scenario. He must layoff one of his valued DBAs the very next morning. Frank asks you: "All else being equal, who would you let go? and Why?" Another pertinent question is raised: "Regardless of good times or bad, if you had to choose, which DBA would you want on your team when tough challenges arise?" Your response is.

• How to add a new item in a sharepoint list using web services in C sharp

  Hi, I'm trying to add a new item to a sharepoint list from a winform application in c# using web services.

• What's a reliable and practical way to protect software with a user license ?

  - by Frank

  I know software companies use licenses to protect their softwares, but I also know there are keygen programs to bypass them. I'm a Java developer, if I put my program online for sale, what's a reliable and practical way to protect it ? How about something like this, would it work ? <1> I use ProGuard to protect the source code. <2> Sign the executable Jar file. <3> Since my Java program only need to work on PC [I need to use JDIC in it], I wrap the final executable Jar into an .exe file which makes it harder to decompile. <4> When a user first downloads and runs my app, it checks for a Pass file on his PC. <5> If the Pass file doesn't exist, run the app in demo mode, exits in 5 minutes. <6> When demo exits a panel opens with a "Buy Now" button. This demo mode repeats forever unless step <7> happens. <7> If user clicks the "Buy Now" button, he fills out a detailed form [name, phone, email ...], presses a "Verify Info" button to save the form to a Pass file, leaving license Key # field empty in this newly generated Pass file. <8> Pressing "Verify Info" button will take him to a html form pre-filled with his info to verify what he is buying, also hidden in the form's input filed is a license Key number. He can now press a "Pay Now" button to goto Paypal to finish the process. <9> The hidden license Key # will be passed to Paypal as product Id info and emailed to me. <10> After I got the payment and Paypal email, I'll add the license Key # to a valid license Key list, and put it on my site, only I know the url. The list is updated hourly. <11> Few hours later when the user runs the app again, it can find the Pass file on his PC, but the license Key # value is empty, so it goes to the valid list url to see if its license Key # is on the list, if so, write the license Key # into the Pass file, and the next time it starts again, it will find the valid license Key # and start in purchased mode without exiting in 5 minutes. <12> If it can't find its license Key # on the list from my url, run in demo mode. <13> In order to prevent a user from copying and using another paid user's valid Pass file, the license Key # is unique to each PC [I'm trying to find how], so a valid Pass file only works on one PC. Only after a user has paid will Paypal email me the valid license Key # with his payment. <14> The Id checking goes like this : Use the CPU ID : "CPU_01-02-ABC" for example, encrypt it to the result ID : "XeR5TY67rgf", and compare it to the list on my url, if "XeR5TY67rgf" is not on my valid user list, run in demo mode. If it exists write "XeR5TY67rgf" into the Pass File license field. In order to get a unique license Key, can I use his PC's CPU Id ? Or something unique and useful [ relatively less likely to change ]. If so let's say this CPU ID is "CPU_01-02-ABC", I can encrypt it to something like "XeR5TY67rgf", and pass it to Paypal as product Id in the hidden html form field, then I'll get it from Paypal's email notification, and add it to the valid license Key # list on the url. So, even if a hacker knows it uses CPU Id, he can't write it into the Pass file field, because only encrypted Ids are valid Ids. And only my program knows how to generate the encrypted Ids. And even if another hacker knows the encrypted Id is hidden in the html form input field, as long as it's not on my url list, it's still invalid. Can anyone find any flaw in the above system ? Is it practical ? And most importantly how do I get hold of this unique ID that can represent a user's PC ? Frank

They do not evaluate single tools anymore for different application areas, but buy into a complete ecosystem of hardware, software and services. The best ecosystem is the one that offers the most options, in environments where the uncertainty is high and investments are hard to reverse. The key to successfully managing such an environment is middleware, and BI and EPM become increasingly middleware intensive. In fact, given the horizontal nature of BI and EPM, sitting on top of all business functions and applications, you could call them 'upperware.'" -- Frank Buytendijk (tags: oracle otn enterprisearchitecture bi)

• ADF sessions at UKOUG conference by Grant Ronald

  - by JuergenKress

  For those in the UK, or those who have a few travel dollars left in their budget I just wanted to hi-light a couple of reasons you might want to present to your management as to why you should attend the UKOUG conference this year to get your ADF fill. Firstly, there are three days packed with the ADF content from the brightest minds in ADF-land. In no particular order, some of the stand out sessions for me will be: Duncan Mills presenting a keynote on the Future of Oracle's Fusion Development Luc Bors will be demoing ADF Mobile Frank Nimphius will be giving a tour around JDeveloper 12c Steven Davelaar of JHeadstart fame will be giving an insight on task flows and ADF Faces. Aino Andriessen will focus on build and deployment Frank Houweling will tell us how he can make your ADF application run 70% faster Chris Muir will give a masterclass on ADF architecture. In addition, the UKOUG will be running a 3 days of ADF Mobile hands-on sessions. Mobile is just about the hottest development topic at this time so this is an ideal opportunity to roll up your sleeves and build on-device mobile applications. There will also be a roundtable discussion on which development tool is right for you, and a roundtable on the strategic importance of ADF. Of course, the conference is not all about ADF; Tom Kyte will be there, Cliff Godwin (SVP who looks after Oracle Applications) and a host of others. This might be a great opportunity to get some ADF education. For more adf information visit Grant Ronald’s blog.

• What I&rsquo;m Reading &ndash; Microsoft Silverlight 4 Business Application Development: Beginner&rs

  - by Dave Campbell

  I don’t have a lot of time for reading lately, so James Patterson and all those guys are *way* ahead of me … but I do try to make time to read technical material. A couple books have come across just recently and I thought I’d mention them one at a time. The book I want to mention tonight is Microsoft Silverlight 4 Business Application Development: Beginner’s Guide : by Cameron Albert and Frank LaVigne. Cameron and Frank are both great guys and you’ve seen their blog posts come across my SilverlightCream posts many times. I like the writing and format of the book. It leads you quite well from one concept to the next and for a technical book, it holds your interest. You can check out a free chapter here. I have the eBook because for technical material, at least lately, I’ve gravitated toward that. I can have it with me on a USB stick at work, or at home. Read the free chapter then check out their blogs. Even if you think you know a lot of this material, I think you’ll find yourself learning something, and besides, it’s a great one-place reference. Good work guys! Technorati Tags: Silverlight 4
