  • Where Have All the Ugly Forms Gone? Users and ADF Took Care Of It

    - by ultan o'broin
    Sometimes I hear that our application demos are a bit too "cutsey" and that we never talk about with any user roles that have lots of data entry as a requirement. Some (no names) consider those old clunker forms, with the myriad rows of fields, to be super-productive for data clerks. We do have such roles covered in Oracle Fusion Applications for sure. But consider what is really the issue here: productivity. Check out how the Oracle Fusion Financials Applications User Experience team went about designing for productivity when receiving and entering invoice data, for example. See how Fusion Financials caters so well for input and control of data? Central to all this is knowing the users and how they work: what tasks do they need to perform, and when. Read more about Fusion Financials productivity in the white paper, Get It Done Fast, Get It Done Right: The Oracle Fusion Financials User Experience. Now and then, I see forms that weren't designed for end user activity at all. Instead, they were designed by developers or by the IT department around the database schema. Forms with literally dozens of fields on the same page, sometimes. Forms that give the impression there was only task involved, when there may have been several. At times, completing one of these huge forms accurately became so tedious that, under pressure, it made more sense for the user to complete it quickly as possible and then let somebody else check it for accuracy and fill in the gaps from data emailed along in spreadsheet form. Data accuracy is critical in our business. Not good. Not efficient. Not productive. So here are a few basics on forms design for data entry-type user roles. A great place for developers to start exploring what is possible with forms layout is the Rich Client User Experience (RCUX) guidance on Form Layout, using ADF components. User-Centered Forms Design Considerations The starting point--something you must always keep in mind with your own design--is design for the end user. Find a representative end user, and keep that user engaged throughout the design, deployment, and test process. Consider these points in user testing those forms: Are there automated or technical solutions to entering the data that avoid manual input in the first place? For example, imports, uploads, OCR, whatever. Some day we will be able to tell Siri to do it, but leave that for now. Design your form to reflect the task involved (i.e., the business process) and not the database schema. On the form, group like fields together, logically. Eliminate duplicate data entry or prepopulate from previous data entry. Allow users to complete fields in the order they wish (i.e., no interdependency). Allow for tabbing between fields (keyboard is faster than mouse), so know how the browser supports this (see that RCUX guideline). Allow for final validation at the page level not at field-level entry. Way better for heads-down users. For example, ADF messages allow you to see a list of all validation errors on a page on a final submit or navigation action and to easily navigate to the point of error. Better still, be error tolerant. Allow users to enter data in formats they comfortable with. Bind any relevant user preference setting to the input format allowed (for example, the locale date format). Explore what data entry conversion can do for you automatically too (see the ADF converter demos, convenience patterns can also be written). Only ask for data input when it's needed. Get rid of, or hide optional fields. Cut down on the number of mandatory fields, and mark them clearly (use a *). Clearly label the fields in plain language. I am sure you may have a few more tips on forms design for data entry users. Remember the user before finding the comments.

  • How likely can my data be recovered after Windows CHKDSK performed on a degraded RAID 5 array?

    - by chrisling106
    Hello there, We have a RAID 5 setup with 3 SATA disks, #2 went down as reported on the pre-POST screen. Unfortunately, for some reason out of my control, the system was rebooted with a degraded RAID :-O Windows XP (64-bit) loaded, CHKDSK ran automatically and done its recovery! From that point onwards, the following error prompts every time even in Safe Mode: lsass.exe - The endpoint format is invalid I took those 3 disks to the data recovery expert and need to wait at least 2-4 days for results. There are 2 VMs on multiple files stored in this RAID 5 array, and there's no backup! Sorry, I just inherited the system from an ex-staff who has left the company 2 months before I joined. How likely the data can be recovered?

  • Hadoop, NOSQL, and the Relational Model

    - by Phil Factor
    (Guest Editorial for the IT Pro/SysAdmin Newsletter)Whereas Relational Databases fit the world of commerce like a glove, it is useless to pretend that they are a perfect fit for all human endeavours. Although, with SQL Server, we’ve made great strides with indexing text, in processing spatial data and processing markup, there is still a problem in dealing efficiently with large volumes of ephemeral semi-structured data. Key-value stores such as Cassandra, Project Voldemort, and Riak are of great value for ephemeral data, and seem of equal value as a data-feed that provides aggregations to an RDBMS. However, the Document databases such as MongoDB and CouchDB are ideal for semi-structured data for which no fixed schema exists; analytics and logging are obvious examples. NoSQL products, such as MongoDB, tackle the semi-structured data problem with panache. MongoDB is designed with a simple document-oriented data model that scales horizontally across multiple servers. It doesn’t impose a schema, and relies on the application to enforce the data structure. This is another take on the old ‘EAV’ problem (where you don’t know in advance all the attributes of a particular entity) It uses a clever replica set design that allows automatic failover, and uses journaling for data durability. It allows indexing and ad-hoc querying. However, for SQL Server users, the obvious choice for handling semi-structured data is Apache Hadoop. There will soon be an ODBC Driver for Apache Hive .and an Add-in for Excel. Additionally, there are now two Hadoop-based connectors for SQL Server; the Apache Hadoop connector for SQL Server 2008 R2, and the SQL Server Parallel Data Warehouse (PDW) connector. We can connect to Hadoop process the semi-structured data and then store it in SQL Server. For one steeped in the culture of Relational SQL Databases, I might be expected to throw up my hands in the air in a gesture of contempt for a technology that was, judging by the overblown journalism on the subject, about to make my own profession as archaic as the Saggar makers bottom knocker (a potter’s assistant who helped the saggar maker to make the bottom of the saggar by placing clay in a metal hoop and bashing it). However, on the contrary, I find that I'm delighted with the advances made by the NoSQL databases in the past few years. Having the flow of ideas from the NoSQL providers will knock any trace of complacency out of the providers of Relational Databases and inspire them into back-fitting some features, such as horizontal scaling, with sharding and automatic failover into SQL-based RDBMSs. It will do the breed a power of good to benefit from all this lateral thinking.

  • Can I run Ubuntu Live from a USB flash-drive without destroying the data on it?

    - by Lucian
    I already have a number of files on a flash drive (8 gb) that I would prefer to keep, but I would like to try Ubuntu even if merely for the aesthetics. I use Windows XP. I know that it's definitely possible to run Ubuntu from a bootable drive like my flash drive to try Ubuntu but I would much rather keep my files intact not only on my flash drive but also my hard drive, if that's possible. I also want to know if it's entirely possible that while running Ubuntu from the USB if I can switch back to Windows while my computer is still on. If I'm missing something, please let me know. I'm very grateful for any assistance in this matter.

  • RESTful API design - should a PUT return related data?

    - by alexmcroberts
    I have an API which allows a user to update their system status; and a separate call to retrieve system status updates from other users. Would it make sense to unify them under a PUT request where a user would request a PUT update with their own status update, and they would receive the status updates of other users? My solution would allow the PUT request to call the GET request method internally. The reason behind this is that when a user updates their system status they should be informed of other users status immediately, and I don't feel that having 2 seperate requests is necessary - and should be optional. I intend to keep the GET request for other users status as a status update for a user is not necessarily required in order to retrieve other users status', but once they update their own status is it vital that they get information about other users.

  • Apache won't follow Symlink

    - by Marvin Dickhaus
    I have a LAMP server (Ubuntu 12.10) setup on my development machine. It is a T60 modified with an SSD. The server base is in /var/www. Apache has the following config: DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews SymLinksIfOwnerMatch AllowOverride all Order allow,deny allow from all </Directory> I'm currently developing a SilverStripe CMS featured site. The folder for the server is /var/www/sfk/. The framework and all cms relavant features are in their respective folders. The only folder that need to be modified would be the /var/www/sfk/mysite folder. Because of that I want to keep the mysite folder under my home directory and symlink it into the server folder. So here is what I've done: ln -s ~/sfk/mysite/ /var/www/sfk/ sudo chgrp www-data /var/www/sfk/mysite -R ls tells me the following: /var/www/sfk (exerpt) drwxr-xr-x 3 marvin www-data 4096 Nov 16 16:53 assets drwxr-xr-x 12 marvin www-data 4096 Nov 16 16:53 cms drwxr-xr-x 29 marvin www-data 4096 Nov 16 16:53 framework -rw-r--r-- 1 marvin www-data 2410 Nov 16 16:53 index.php lrwxrwxrwx 1 marvin www-data 24 Nov 20 17:45 mysite -> /home/marvin/sfk/mysite/ -rw-rw-r-- 1 marvin www-data 514 Nov 16 16:55 _ss_environment.php drwxr-xr-x 4 marvin www-data 4096 Nov 16 16:53 themes and ls /var/www/sfk/mysite/ drwxrwxr-x 6 marvin www-data 4096 Nov 16 00:15 code drwxrwxr-x 2 marvin www-data 4096 Nov 16 11:51 _config -rwxrwxr-x 1 marvin www-data 2685 Nov 16 15:39 _config.php drwxrwxr-x 2 marvin www-data 4096 Nov 16 00:15 css drwxrwxr-x 2 marvin www-data 4096 Nov 16 00:15 images drwxrwxr-x 2 marvin www-data 4096 Nov 16 00:15 javascript drwxrwxr-x 5 marvin www-data 4096 Nov 16 00:15 templates This is literally the same setup I have on my desktop machine. The problem I have is that the mysite/ folder is just not recognized. I'm thankful for every advice I get. I'm frustrated because I'm stuck with this issue for hours.

  • Revisiting the Generations

    - by Row Henson
    I was asked earlier this year to contribute an article to the IHRIM publication – Workforce Solutions Review.  My topic focused on the reality of the Gen Y population 10 years after their entry into the workforce.  Below is an excerpt from that article: It seems like yesterday that we were all talking about the entry of the Gen Y'ers into the workforce and what a radical change that would have on how we attract, retain, motivate, reward, and engage this new, younger segment of the workforce.  We all heard and read that these youngsters would be more entrepreneurial than their predecessors – the Gen X'ers – who were said to be more loyal to their profession than their employer. And, we heard that these “youngsters” would certainly be far less loyal to their employers than the Baby Boomers or even earlier Traditionalists. It was also predicted that – at least for the developed parts of the world – they would be more interested in work/life balance than financial reward; they would need constant and immediate reinforcement and recognition and we would be lucky to have them in our employment for two to three years. And, to keep them longer than that we would need to promote them often so they would be continuously learning since their long-term (10-year) goal would be to own their own business or be an independent consultant.  Well, it occurred to me recently that the first of the Gen Y'ers are now in their early 30s and it is time to look back on some of these predictions. Many really believed the Gen Y'ers would enter the workforce with an attitude – expect everything to be easy for them – have their employers meet their demands or move to the next employer, and I believe that we can now say that, generally, has not been the case. Speaking from personal experience, I have mentored a number of Gen Y'ers and initially felt that with a 40-year career in Human Resources and Human Resources Technology – I could share a lot with them. I found out very quickly that I was learning at least as much from them! Some of the amazing attributes I found from these under-30s was their fearlessness, ease of which they were able to multi-task, amazing energy and great technical savvy. They were very comfortable with collaborating with colleagues from both inside the company and peers outside their organization to problem-solve quickly. Most were eager to learn and willing to work hard.  This brings me to the generation that will follow the Gen Y'ers – the Generation Z'ers – those born after 1998. We have come full circle. If we look at the Silent Generation or Traditionalists, we find a workforce that preceded the television and even very early telephones. We Baby Boomers (as I fall right squarely in this category) remembered the invention of the television and telephone – but laptop computers and personal digital assistants (PDAs) were a thing of “StarTrek” and other science fiction movies and publications. Certainly, the Gen X'ers and Gen Y'ers grew up with the comfort of these devices just as we did with calculators. But, what of those under the age of 10 – how will the workplace look in 15 more years and what type of workforce will be required to operate in the mobile, global, virtual world. I spoke to a friend recently who had her four-year-old granddaughter for a visit. She said she found her in the den in front of the TV trying to use her hand to get the screen to move! So, you see – we have come full circle. The under-70 Traditionalist grew up in a world without TV and the Generation Z'er may never remember the TV we knew just a few years ago. As with every generation – we spend much time generalizing on their characteristics. The most important thing to remember is every generation – just like every individual – is different. The important thing for those of us in Human Resources to remember is that one size doesn’t fit all. What motivates one employee to come to work for you and stay there and be productive is very different than what the next employee is looking for and the organization that can provide this fluidity and flexibility will be the survivor for generations to come. And, finally, just when we think we have it figured out, a multitude of external factors such as the economy, world politics, industries, and technologies we haven’t even thought about will come along and change those predictions. As I reach retirement age – I do so believing that our organizations are in good hands with the generations to follow – energetic, collaborative and capable of working hard while still understanding the need for balance at work, at home and in the community!

  • Data recovery on Ubuntu 11.10?! (after crashing with Seagate 320GB)

    - by Sam
    Just installed 11.10 last week and decided to transfer iTunes music (from Windows dual boot) to my Seagate 320GB. I left it in, restarted, clicked Ubuntu at the boot screen, and then it froze after a few lines of code! I think I got to 3.7086 or something before I pressed CTRL+ALT+DEL and the system restarted after another few lines of code. I am completely new to Ubuntu so after Googling, I made a live CD with 10.04, the most stable release I've heard, and I'm typing this from there now. However, when I go to mount my partition, only the Windows Vista partition (308GB) is there! It has all my Windows files but my Ubuntu 11.10 ones are nowhere to be found. I need to restore these pictures I transferred from my camera using Shotwell the other day... any help is appreciated! p.s. 11.10 has never crashed on me in my trial week, so I'm guessing it's the Seagate hard drive's fault. However, now I'm running it on 10.04 and it works fine.

  • How to do MVC the right way

    - by Ieyasu Sawada
    I've been doing MVC for a few months now using the CodeIgniter framework in PHP but I still don't know if I'm really doing things right. What I currently do is: Model - this is where I put database queries (select, insert, update, delete). Here's a sample from one of the models that I have: function register_user($user_login, $user_profile, $department, $role) { $department_id = $this->get_department_id($department); $role_id = $this->get_role_id($role); array_push($user_login, $department_id, $role_id); $this->db->query("INSERT INTO tbl_users SET username=?, hashed_password=?, salt=?, department_id=?, role_id=?", $user_login); $user_id = $this->db->insert_id(); array_push($user_profile, $user_id); $this->db->query(" INSERT INTO tbl_userprofile SET firstname=?, midname=?, lastname=?, user_id=? ", $user_profile); } Controller - talks to the model, calls up the methods in the model which queries the database, supplies the data which the views will display(success alerts, error alerts, data from database), inherits a parent controller which checks if user is logged in. Here's a sample: function create_user(){ $this->load->helper('encryption/Bcrypt'); $bcrypt = new Bcrypt(15); $user_data = array( 'username' => 'Username', 'firstname' => 'Firstname', 'middlename' => 'Middlename', 'lastname' => 'Lastname', 'password' => 'Password', 'department' => 'Department', 'role' => 'Role' ); foreach ($user_data as $key => $value) { $this->form_validation->set_rules($key, $value, 'required|trim'); } if ($this->form_validation->run() == FALSE) { $departments = $this->user_model->list_departments(); $it_roles = $this->user_model->list_roles(1); $tc_roles = $this->user_model->list_roles(2); $assessor_roles = $this->user_model->list_roles(3); $data['data'] = array('departments' => $departments, 'it_roles' => $it_roles, 'tc_roles' => $tc_roles, 'assessor_roles' => $assessor_roles); $data['content'] = 'admin/create_user'; parent::error_alert(); $this->load->view($this->_at, $data); } else { $username = $this->input->post('username'); $salt = $bcrypt->getSalt(); $hashed_password = $bcrypt->hash($this->input->post('password'), $salt); $fname = $this->input->post('firstname'); $mname = $this->input->post('middlename'); $lname = $this->input->post('lastname'); $department = $this->input->post('department'); $role = $this->input->post('role'); $user_login = array($username, $hashed_password, $salt); $user_profile = array($fname, $mname, $lname); $this->user_model->register_user($user_login, $user_profile, $department, $role); $data['content'] = 'admin/view_user'; parent::success_alert(4, 'User Sucessfully Registered!', 'You may now login using your account'); $data['data'] = array('username' => $username, 'fname' => $fname, 'mname' => $mname, 'lname' => $lname, 'department' => $department, 'role' => $role); $this->load->view($this->_at, $data); } } Views - this is where I put html, css, and JavaScript code (form validation code for the current form, looping through the data supplied by controller, a few if statements to hide and show things depending on the data supplied by the controller). <!--User registration form--> <form class="well min-form" method="post"> <div class="form-heading"> <h3>User Registration</h3> </div> <label for="username">Username</label> <input type="text" id="username" name="username" class="span3" autofocus> <label for="password">Password</label> <input type="password" id="password" name="password" class="span3"> <label for="firstname">First name</label> <input type="text" id="firstname" name="firstname" class="span3"> <label for="middlename">Middle name</label> <input type="text" id="middlename" name="middlename" class="span3"> <label for="lastname">Last name</label> <input type="text" id="lastname" name="lastname" class="span3"> <label for="department">Department</label> <input type="text" id="department" name="department" class="span3" list="list_departments"> <datalist id="list_departments"> <?php foreach ($data['departments'] as $row) { ?> <option data-id="<?php echo $row['department_id'];

?>" value="<?php echo $row['role']; ?>"><?php echo $row['role']; ?></option> <?php } ?> </datalist> <p> <button type="submit" class="btn btn-success">Create User</button> </p> </form> <script> var departments = []; var roles = []; $('#list_departments option').each(function(i){ departments[i] = $(this).val(); }); $('#list_it option').each(function(i){ roles[roles.length + 1] = $(this).val(); }); $('#list_collection option').each(function(i){ roles[roles.length + 1] = $(this).val(); }); $('#list_assessor option').each(function(i){ roles[roles.length + 1] = $(this).val(); }); $('#department').blur(function(){ var department = $.trim($(this).val()); $('#role').attr('list', 'list_' + department); }); var password = new LiveValidation('password'); password.add(Validate.Presence); password.add(Validate.Length, {minimum: 10}); $('input[type=text]').each(function(i){ var field_id = $(this).attr('id'); var field = new LiveValidation(field_id); field.add(Validate.Presence); if(field_id == 'department'){ field.add(Validate.Inclusion, {within : departments}); } else if(field_id == 'role'){ field.add(Validate.Inclusion, {within : roles}) } }); </script> The codes above are actually code from the application that I'm currently working on. I'm working on it alone so I don't really have someone to review my code for me and point out the wrong things in it so I'm posting it here in hopes that someone could point out the wrong things that I've done in here. I'm also looking for some guidelines in writing MVC code like what are the things that should be and shouldn't be included in views, models and controllers. How else can I improve the current code that I have right now. I've written some really terrible code before(duplication of logic, etc.) that's why I want to improve my code so that I can easily maintain it in the future. Thanks!

  • How do I analyze vague Google Analytics data re traffic from Facebook?

    - by user6982
    We have one Facebook fan page and two personal profiles that could be sending traffic and then there are the many facebook pages of friends etc. I am also running an ad campaign from my FB account for my husband's business which has a link from his personal FB profile and his fan page. On Google analytics for his business we get the following referring sites from Facebook: /ajax/emu/end.php which is listed under facebook.com / referral /l.php (which is a not-found page at FB /ajax/emu/end.php which is listed under apps.facebook.com Both of the working links send me to the home page of my profile, which is the account I am working from to create and review the FB ad campaign that we are running. Is this info telling me any useful information at all? Is there a best practice for tracking and analyzing Facebook traffic that is a lot more granular? thanks!

  • How can I copy data from a windows disk to another partition?

    - by TardisGuy
    I have a new Solid State Drive, and it's very fast (but tiny, 128GB). But it seems to be much faster in Linux. Now, am I correct in assuming that if I Gparted copy paste the {_Boot MSreserved__][_________NTFS__________] in to (1st Empty space, same partition) and it will be bootable, right? Will this work? I also heard I should turn off 'journaling' for the SSD filesystem. Is that needed for this as well?

  • A way to store potentially infinite 2D map data?

    - by Blam
    I have a 2D platformer that currently can handle chunks with 100 by 100 tiles, with the chunk coordinates are stored as longs, so this is the only limit of maps (maxlong*maxlong). All entity positions etc etc are chunk relevant and so there is no limit there. The problem I'm having is how to store and access these chunks without having thousands of files. Any ideas for a preferably quick & low HD cost archive format that doesn't need to open everything at once?

    When I plug in this external harddisk It is not getting shown in the My Computer. But it gets shown perfectly well in the Device Manager When I go into the Computer Administrative panel and into the disk manager it asks me to initialize the disk Now when I try to initialize it, regardless of the method I try it shows me an error "Incorrect Function" As you can see windows tells me it is working properly. Is there anyway I can retrieve data from this?/access it? I have googled and it seems to be a frequent problem with WD drives. Anyone has any solutions on how I can get the data back?

  • How to have an Arduino wait until it receives data over serial?

    - by SonicDH
    So I've wired up a little robot with a sound shield and some sensors. I'm trying to write a sketch that will let check the sensors. What I'd like for it to do is print out a little menu over serial, wait until the user sends a selection, jump to the function that matches their selection, then (once the function is done) jump back and print the menu again. Here's what I've written, but I'm not a that good of a coder, so it doesn't work. Where am I going wrong? #include <Servo.h> Servo steering; Servo throttle; int pos = 0; int val = 0; void setup(){   Serial.begin(9600);   throttle.write(90);   steering.write(90);   pinMode(A0, INPUT);   pinMode(7, INPUT);   char ch = 0; } void loop(){   Serial.println("Menu");   Serial.println("--------------------");   Serial.println("1. Motion Readout");   Serial.println("2. Distance Readout");   Serial.println("3. SD Directory Listing");   Serial.println("4. Sound Test");   Serial.println("5. Car Test");   Serial.println("--------------------");   Serial.println("Type the number and press enter");   while(char ch = 0){   ch = Serial.read();}   char ch;   switch(ch)   {     case '1':     motion();   }    ch = 0; } //menu over, lets get to work. void motion(){   Serial.println("Haha, it works!"); } I'm pretty sure a While loop is the right thing to do, but I'm probably implementing it wrong. Can anyone shed some light on this?

  • Correct permissions for /var/www and wordpress

    Hello and thank you in advance! I am relatively new to ubuntu, so please excuse the newbie-ness of this question... I have set up a LAMP server (ubuntu server 11.10) and I have access via SSH and to the "it works" page from a web browser from inside my network (via ip address) and from outside using dyndns. I have a couple of projects in development with some outside developers and I want to use this server as a development server for testing and for client approvals. We have some Wordpress projects that sit in subdirectories in /var/www/wordpress1 /var/www/wordpress2, etc. I cannot access these sub directories from a browser in order to set up WP--or (I assume) to see the content on a browser. I get a 403 Forbidden error on my browser. I assume that this is a permissions problem. Can you please tell me the proper settings for the permissions to: 1) Allow the developers and me to read/write. 2) to allow WP set up and do its thing 3) Allow visitors to access the site(s) via the web. I should also mention that the subfolder are actually simlinks to folder on another internal hdd--I don't think this will make a difference, but I thought I should disclose. Since I am a newbie to ubuntu, step-by-step directions are greatly appreciated! Thank you for taking the time! dp total 12 drwxr-xr-x 2 root root 4096 2012-07-12 10:55 . drwxr-xr-x 13 root root 4096 2012-07-11 20:02 .. lrwxrwxrwx 1 root root 43 2012-07-11 20:45 admin_media -> /root/django_src/django/contrib/admin/media -rw-r--r-- 1 root root 177 2012-07-11 17:50 index.html lrwxrwxrwx 1 root root 14 2012-07-11 20:42 media -> /hdd/web/media lrwxrwxrwx 1 root root 18 2012-07-12 10:55 wordpress -> /hdd/web/wordpress Here is the result of using chown -R www-data:www-data /var/www total 12 drwxr-xr-x 2 www-data www-data 4096 2012-07-12 10:55 . drwxr-xr-x 13 root root 4096 2012-07-11 20:02 .. lrwxrwxrwx 1 www-data www-data 43 2012-07-11 20:45 admin_media -> /root/django_src/django/contrib/admin/media -rw-r--r-- 1 www-data www-data 177 2012-07-11 17:50 index.html lrwxrwxrwx 1 www-data www-data 14 2012-07-11 20:42 media -> /hdd/web/media lrwxrwxrwx 1 www-data www-data 18 2012-07-12 10:55 wordpress -> /hdd/web/wordpress I am still unable to access via browser...

  • Are We Losing a Standard (Edition) Data Recovery Technology?

    - by AllenMWhite
    One of the coolest technologies Microsoft released with SQL Server 2005 was Database Mirroring, which provided the ability to have a failover copy of a database on another SQL Server instance, and have the ability to automatically failover to that copy should a problem occur with the primary database. What was even cooler was that this new technology was available on Standard Edition! Mom and Pop shops could afford to implement a high availability solution without paying an extra tens of thousands...(read more)

  • How can I write data to a file that users can't easily edit?

    - by ThePlan
    While working on game saving and loading I figured I could just write all the variable values to a file and then load that file from it's default location anytime. However from the very beginning it sounded like an odd job. I know about serialization and boost, but that seems so complicated, I figured I'd keep it simple, but I've ran across this huge issue: No matter what file I can write with C++, the user can get their hands on it, they can edit their position, they can remove a boss, or add new weapons for themselves. My question here is: How can I create a file in C++ which cannot be editted or openned with a text editor such as Notepad (I'm not trying to make a file which is impossible to open, but a file which will give the user a headache if he tries to edit it through usual methods.)

  • How can I locate the frames of a spritesheet PNG based on this PLIST data?

    - by kitsune
    Someone asked me to reskin a certain game. Now he only sent me the whole sprite PNG and PLIST files of the sprites. He instructed me to rename each sprite with the same name corresponding to each original sprite. The problem is, he gave me the whole sprite sheet instead of each individual sprite and the PLIST. Now yes, I can read the PNG filenames from the PLIST, but I cannot rename the reskin sprites I did because I'm not sure which sprite is boy_gun_3_3.png; there are multiple guns, I don't know which is which. Is there a way to extract individual accurately named individual PNG files from the single sprite sheet using the PLIST?

  • How to avoid oscillation by async event based systems?

    - by inf3rno
    Imagine a system where there are data sources which need to be kept in sync. A simple example is model - view data binding by MVC. Now I intend to describe these kind of systems with data sources and hubs. Data sources are publishing and subscribing for events and hubs are relaying events to data sources. By handling an event a data source will change it state described in the event. By publishing an event the data source puts its current state to the event, so other data sources can use that information to change their state accordingly. The only problem with this system, that events can be reflected from the hub or from the other data sources, and that can put the system into an infinite oscillation (by async or infinite loop by sync). For example A -- data source B -- data source H -- hub A -> H -> A -- reflection from the hub A -> H -> B -> H -> A -- reflection from another data source By sync it is relatively easy to solve this issue. You can compare the current state with the event, and if they are equal, you don't change the state and raise the same event again. By async I could not find a solution yet. The state comparison does not work by async event handling because there is eventual consistency, and new events can be published in an inconsistent state causing the same oscillation. For example: A(*->x) -> H -> B(y->x) -- can go parallel with B(*->y) -> H -> A(x->y) -- so first A changes to x state while B changes to y state -- then B changes to x state while A changes to y state -- and so on for eternity... What do you think is there an algorithm to solve this problem? If there is a solution, is it possible to extend it to prevent oscillation caused by multiple hubs, multiple different events, etc... ? update: I don't think I can make this work without a lot of effort. I think this problem is just the same as we have by syncing multiple databases in a distributed system. So I think what I really need is constraints if I want to prevent this problem in an automatic way. What constraints do you suggest?

  • How to "paint" the data layer of a CD using a CD drive?

    - by Jens
    I am looking for software to "paint" geometric shapes, dots or lines on the data layer of a writable CD (or DVD) using a standard drive. These do not have to be visible to the naked eye; I'd try to abuse the small dot size on the CD for some scientific measurements. I am aware of the "LightScribe" feature of some drives and that is not what I am looking for. Most of the software available is of course limited to write music or data, on does not offer the low-level "place a dot at this radius, this angle"-functionality. Is there something out there for me?
