• Simultaneous AI in turn based games

  - by Eduard Strehlau

  I want to hack together a roguelike. Now I thought about entity and world representation and got to a quite big problem. If you want all the AI to act simultaneously you would normally(in cellular automa for examble) just copy the cell buffer and let all action of indiviual cells depend on the copy. Actions which are not valid anymore after some cell before the cell you are currently operating on changed the original enviourment(blocking the path) are just ignored or reapplied with the "current"(between turns) environment. After all cells have acted you copy the current map to the buffer again. Now for an environment with complex AI and big(datawise) entities the copying would take too long. So I thought you could put every action and entity makes into a que(make no changes to the environment) and execute the whole que after everyone took their move. Every interaction on this que are realy interacting entities, so if a entity tries to attack another entity it sends a message to it, the consequences of the attack would be visible next turn, either by just examining the entity or asking the entity for data. This would remove problems like what happens if an entity dies middle in the cue but got actions or is messaged later on(all messages would go to null, and the messages from the entity would either just be sent or deleted(haven't decided yet) But what would happen if a monster spawns a fireball which by itself tracks the player(in the same turn). Should I add the fireball to the enviourment beforehand, so make a change to the environment before executing the action list or just add the ball to the "need updated" list as a special case so it doesn't exist in the environment and still operates on it, spawing after evaluating the action list? Are there any solutions or papers on this subject which I can take a look at? EDIT: I don't need information on writing a roguelike I need information on turn based ai in respective to a complex enviourment.

• Oracle Inroduces a New Line of Defense for Databases

  - by roxana.bradescu

  Today at the 2011 RSA Conference, we announced the immediate availability of our new Oracle Database Firewall, the latest addition to a comprehensive portfolio of database security solutions. Oracle Database Firewall is a network-based software solution that monitors database traffic, and can detect and block SQL injection and other attacks from reaching Oracle and non-Oracle databases. According to the 2010 Verizon Data Breach Investigations Report, SQL injection attacks against databases are responsible for 89% of all breached data. SQL injection attacks are a technique for controlling responses from the database server through applications. This attack exploits the inherent trust between application layer and the back-end database. Previously the only way organizations had to safeguard against SQL injection attacks was a complete overhaul of their application code. Obviously a very costly, complex, and often impossible undertaking for most organizations. Enter the new Oracle Database Firewall. It can help prevent SQL injection attacks by establishing a defensive perimeter around your databases. The Oracle Database Firewall uses an innovative SQL grammar analysis to inspect the database traffic against pre-defined policies. Normal expected traffic is allowed to pass (and can be optionally logged to demonstrate regulatory compliance), ensuring no false positives or disruption to your business. SQL statements that are explicitly forbidden or unknown SQL statements can either pass, be logged, alert, block or be substitute with pre-defined SQL statements. Being able to substitute an unknown potentially harmful SQL statement with a harmless statement is especially powerful since it foils an attack while allowing the application to operate normally and preventing DoS attacks. So, if you're at RSA, stop by our booth or attend the session with Steve Moyle, Oracle Database Firewall CTO. Or if you want to learn more immediately, please watch our on-demand webcast and download the new Oracle Database Firewall Resource Kit with everything you need to get started today.

• SQL SERVER – Follow up – Usage of $rowguid and $IDENTITY

  - by pinaldave

  The most common question I often receive is why do I blog? The answer is even simpler – I blog because I get an extremely constructive comment and conversation from people like DHall and Kumar Harsh. Earlier this week, I shared a conversation between Madhivanan and myself regarding how to find out if a table uses ROWGUID or not? I encourage all of you to read the conversation here: SQL SERVER – Identifying Column Data Type of uniqueidentifier without Querying System Tables. In simple words the conversation between Madhivanan and myself brought out a simple query which returns the values of the UNIQUEIDENTIFIER  without knowing the name of the column. David Hall wrote few excellent comments as a follow up and every SQL Enthusiast must read them first, second and third. David is always with positive energy, he first of all shows the limitation of my solution here and here which he follows up with his own solution here. As he said his solution is also not perfect but it indeed leaves learning bites for all of us – worth reading if you are interested in unorthodox solutions. Kumar Harsh suggested that one can also find Identity Column used in the table very similar way using $IDENTITY. Here is how one can do the same. DECLARE @t TABLE ( GuidCol UNIQUEIDENTIFIER DEFAULT newsequentialid() ROWGUIDCOL, IDENTITYCL INT IDENTITY(1,1), data VARCHAR(60) ) INSERT INTO @t (data) SELECT 'test' INSERT INTO @t (data) SELECT 'test1' SELECT $rowguid,$IDENTITY FROM @t There are alternate ways also to find an identity column in the database as well. Following query will give a list of all column names with their corresponding tablename. SELECT SCHEMA_NAME(so.schema_id) SchemaName, so.name TableName, sc.name ColumnName FROM sys.objects so INNER JOIN sys.columns sc ON so.OBJECT_ID = sc.OBJECT_ID AND sc.is_identity = 1 Let me know if you use any alternate method related to identity, I would like to know what you do and how you do when you have to deal with Identity Column.

• does my js replace view?

  - by Milla Well

  I am writing a web application which is based on Codeigniter and jQuery. I primarily use ajax to call my controller functions and it turned out, that there are just 4 view*.php files, because most of my contoller functions return JSON data, which is processed in my jQuery. So my actual code is divided in kind of MVCC model: Codeigniter model (db, computations) Codeigniter controller (filtering, xss-cleaning, checking permissions, call model functions) jQuery controller (callback functions) jQuery view (adding/removing classes, appending elements,... ) So I violate the paradigm of not using the echo function in my Codeiginter controller and simply call echo json_encode($result); because it doesn't make any sense to me to create a view*.php file for one loc. Especially because all the regular view*.php stuff is covered in my jQuery view. I was wondering if I am missing something out, or if there is a way to integrate this jQuery-controller in my Codeigniter. I found some words on this topic, but this seems pretty handmade. Are there some neat solutions? Does a MVCC model make sense?

• Wammu - USB Device Name?

  - by Paul

  I'm trying to get to my phone's filesystem through USB in Wammu, but I'm stuck in the configuration wizard when it asks for a USB device name. After about an hour of Internet searching, here are the failed solutions I've already tried, starting with the relevant information returned by lsusb in terminal. lsusb Bus 001 Device 003: ID 12d1:101e Huawei Technologies Co., Ltd. So I tried opening Wammu through sudo wammu in terminal and inputting "/dev/bus/usb/001/003" as the device name, which returns: Error opening device Device /dev/bus/usb/001/003 does not exist! and then "/dev/bus/usb/001/", which returns: Failed to connect to phone Description: Error opening device. Unknown, busy, or no permissions.<br> Function: Init<br> Error code: 2 Another proposed solution was to try "tail -f /var/log/messages" in terminal. But that only returned a "No such file or directory" message. Seemingly relevant dmesg info: [ 4739.716214] usb 1-1: new high-speed USB device number 8 using ehci_hcd [ 4739.854137] scsi9 : usb-storage 1-1:1.0 [ 4740.854416] scsi 9:0:0:0: CD-ROM HUAWEI T Mass Storage 2.31 PQ: 0 ANSI: 2 [ 4740.867051] sr0: scsi-1 drive [ 4740.867806] sr 9:0:0:0: Attached scsi CD-ROM sr0 [ 4740.870464] sr 9:0:0:0: Attached scsi generic sg1 type 5 I don't know why it is coming up as CD-ROM. But there it is. If you haven't noticed already, I'm an absolute beginner when it comes to Linux and terminal. So speaking to me like I'm a three year old is welcome if you can propose a solution. I'm running Ubuntu 12.04 LTS, and the phone is a Huawei U1250. My computer is an Acer Aspire One D250/KAV60. Any help is much appreciated.

• Drawing particles as a smooth blob

  - by Nömmik

  I'm new to game/graphics development and I'm playing around with particles (in 2D). I want to draw particles close to each other as a blob, just as liquid/water. I do not want to draw big circles overlapping as the blob won't be smooth (and too big). I don't really know physics but I assume what I want is something looking similar to surface tension. I haven't been able to find anything on stackexchange or on Google (maybe I do not know the correct keywords?). So far I have found two possible solutions, but I am unable to find any concrete information about algorithms. One of them is to calculate the concave hull of particles I consider being a blob. I can calculate the blob by creating an equivalence class (on the relation "close to each other"). Strangely enough I haven't been able to find any algorithm explaining how to calculate the concave hull. Many posts (and among stackexchange) links to libraries or commercial products that do this (I need libraries to work in C#), but never any algorithm. Also this solution might have a problem with a circle of particles, which would not detect the empty space in the middle. While researching concave hull I stumbled upon something called alpha shapes. Which seems to be exactly what I want to do, however just as with concave hull I haven't found any source explaining how they actually work. I have found some presentation materials but not enough to go on. It's like a big secret everyone knows except me :-/ After calculating the concave hull or alpha shape I want to make it a Bézier curve to make it smooth and nice. Although I do find my approach a bit too complex, maybe I am trying to solve this the wrong way? If you can either suggest any other solution to my problem, or explain the pieces I am missing I would be very happy and grateful :-) Thanks.

• Is the development of CLI apps considered "backward"?

  - by user61852

  I am a DBA fledgling with a lot of experience in programming. I have developed several CLI, non interactive apps that solve some daily repetitive tasks or eliminate the human error from more complex albeit not so daily tasks. These tools are now part of our tool box. I find CLI apps are great because you can include them in an automated workflow. Also the Unix philosophy of doing a single thing but doing it well, and letting the output of a process be the input of another, is a great way of building a set of tools than would consolidate into an strategic advantage. My boss recently commented that developing CLI tools is "backward", or constitutes a "regression". I told him I disagreed, because most CLI tools that exist now are not legacy but are live projects with improved versions being released all the time. Is this kind of development considered "backwards" in the market? Does it look bad on a rèsumè? I also considered all solutions whether they are web or desktop, should have command line, non-interactive options. Some people consider this a waste of programming resources. Is this goal a worthy one in a software project?

• How to share problem solving knowledge in a multiteam group?

  - by jonathan

  I've been working in multiteam groups for as long as I'm a webdeveloper, for me a team can be a lonely soldier or several people, generally a company will have multiple teams working in different projects and once the project is out in the wild, any team can perform the maintenance. This is a small picture since I'm not talking only about project wise knowledge, but "craft wise" knowledge, but it gives the picture of how I'm used to work, so: Since we work on modularised teams, sometimes I feel like the teams are too tightly enclosed in their projects, I've seen cases where after an hour of discussion, someone asked the question aloud and other person totally unrelated answered in a much simpler fashion. The problem is not so simple to solve as people tend not to be available all the time, also sometimes people can't afford the time to go through a problem with the "asker", but could do it alone. I've thought about software based solutions, something in the lines of SE, but I'd like to know other programmers opinions on the subject. EDIT I don't know if this is a wikipedia complex, but I feel that Wikis don't encourage the user to actually ask questions, but rather to write articles, and sometimes we don't know the knowledge we need, before needing it.

• Starcraft II on Wine - Ubuntu 12.04

  - by Robert Segerson

  I know this might seem like a repeat question, but I've literally looked over 100 threads on how to get SC2 to work on ubuntu 12.04 through wine and none have worked. I downloaded wine new today, and inserted my purchased SC2 disk. When I try to open the installer (installer.exe) with wine, an error appear saying: "No installer data could be found. If this problem persists, please contact Blizzard Technical Support." I searched for solutions to mediate this issue and was directed to the following source: http://ubuntuforums.org/showthread.php?t=1435314 . I followed directions through until I got to ls I tried various combinations of (ls installer.exe, ls'/home/rothic/Desktop/Installer.exe, etc.) All come back with "no such file or directory". Im not sure what to do, the next step would be to replace the "starcraft_installer" with the starcraft installer file, which Im not sure how to do (very new to linux). I tried WINEPREFIX=~/.wine_starcraft/ wine starcraft_installer and it says "wine: cannot find L"C:\windows\system32\starcraft_installer.exe" despite it being on the desktop as advised. Any suggestions on where to go from here?

• Why do programmers write applications and then make them free?

  - by Ken

  As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubical. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.

• Applying WCAG 2.0 to Non-Web ICT: second draft published from WCAG2ICT Task Force - for public review

  - by Peter Korn

  Last Thursday the W3C published an updated Working Draft of Guidance on Applying WCAG 2.0 to Non-Web Information and Communications Technologies. As I noted last July when the first draft was published, the motivation for this guidance comes from the Section 508 refresh draft, and also the European Mandate 376 draft, both of which seek to apply the WCAG 2.0 level A and AA Success Criteria to non-web ICT documents and software. This second Working Draft represents a major step forward in harmonization with the December 5th, 2012 Mandate 376 draft documents, including specifically Draft EN 301549 "European accessibility requirements for public procurement of ICT products and services". This work greatly increases the likelihood of harmonization between the European and American technical standards for accessibility, for web sites and web applications, non-web documents, and non-web software. As I noted last October at the European Policy Centre event: "The Accessibility Act – Ensuring access to goods and services across the EU", and again last month at the follow-up EPC event: "Accessibility - From European challenge to global opportunity", "There isn't a 'German Macular Degernation', a 'French Cerebral Palsy', an 'American Autism Spectrum Disorder'. Disabilities are part of the human condition. They’re not unique to any one country or geography – just like ICT. Even the built environment – phones, trains and cars – is the same worldwide. The definition of ‘accessible’ should be global – and the solutions should be too. Harmonization should be global, and not just EU-wide. It doesn’t make sense for the EU to have a different definition to the US or Japan." With these latest drafts from the W3C and Mandate 376 team, we've moved a major step forward toward that goal of a global "definition of 'accessible' ICT." I strongly encourage all interested parties to read the Call for Review, and to submit comments during the current review period, which runs through 15 February 2013. Comments should be sent to public-wcag2ict-comments-AT-w3.org. I want to thank my colleagues on the WCAG2ICT Task Force for the incredible time and energy and expertise they brought to this work - including particularly my co-authors Judy Brewer, Loïc Martínez Normand, Mike Pluke, Andi Snow-Weaver, and Gregg Vanderheiden; and the document editors Michael Cooper, and Andi Snow-Weaver.

  I have installed Ubuntu 12.04 on my preinstalled windows 7 Sony vaio E series laptop following instructions here: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/ Everything went well and I am able to boot in to windows after complete installation of Ubuntu. Now following instructions on web I tried to add Ubuntu to my BIOS using Easy BCD (but forget to add windows 7 entry). As a result, I loose windows 7 OS and can't boot in to either OS then I successfully repaired windows 7 using recovery CD. Now my problem is that I can't reinstall Ubuntu 12.04 using Live CD it halts every time before disk partition step giving error. "ubi-partman crashed". "ubi-partman failed with exit code 141. further information may be found in /var/log/syslog. Do you want to try running this step again before continuing? If you do not, your installation may fail entirely or may be broken." and, any choice to continue will result in the same error. After that following some post solutions I ran boot-repair commands in terminal ( in Try Ubuntu mode) and got the following URL: http://paste.ubuntu.com/1206434/ Now, after restart I can't boot into either Windows or Ubuntu. Even any attempt to run Windows repair is failed and I got the message : 'No operating System found' I don't know what went wrong after running boot-repair command. Please help in solving this issue.

  hey there i know people have encountered issues with it before i looked upon the different solutions provided but i couldnt get any fix at all.im making a 2d game and am stuck with the walljump.i detect the wall wonderfully i also detect the jump and it works the player jumps off the wall when facing right with the use of rigidbody.addforce(new vector2(-1,2)*jumpforce) now when jumping on the oposite wall using the same vector with the sign in x axis changed to 1,the player jumps too but it goes more in the y axis than it should.Here is an image to show you the curves it(the player) follows. check the following url to see the behaviour https://scontent-b-mad.xx.fbcdn.net/hphotos-xpf1/t1.0-9/1470386_10152415957141154_156025539179003805_n.jpg voila the green one is happennig when player faces right and the other one happens when he is not here is the section of code if (wall) { if (wallJump) { if (facingRight) { rigidbody2D.velocity = Vector2.zero; flip (); rigidbody2D.AddForce (new Vector2 (-1f, 2f) * Jumpforce / 1.5f); Debug.Log ("saut mural gauche" + new Vector2 (-1f, 2f) * Jumpforce / 1.5f); } else { rigidbody2D.velocity = Vector2.zero; flip (); rigidbody2D.AddForce (new Vector2 (1f, 2f) * Jumpforce / 1.5f); Debug.Log ("saut mural droit--" + new Vector2 (Mathf.Sign (1f), 2f) * Jumpforce / 1.5f + "jump" + jump); } } } else { wallJump = false; } here the code is not optimized yet but i assure you it works so guys any help would be so awesome!! thanks

• How to build Gantt chart from a set of Redmine tickets without filling dates in all of them?

  - by Alexander Gladysh

  Redmine 1.1.1 I've created a set of tickets for a new project. In each issue I filled Subject, Description and Estimated time fields. I also filled blocks/blocked by dependencies in Related issues. But the Gantt chart for this project is empty (that is, it contains all the tasks, but does not contain any "bars" for them). I need to get a Gantt chart (or any other visual representation) to show to other project members. I'd hate to type all that information again into OpenProj. Is there a way to get a serviceable Gantt chart from the Redmine? Update: In the answers below I read that to get working Gantt chart I have to input start date and due date manually for each issue. I believe that this information should be inferred automatically from start date of first ticket (first — depenency-wise), estimated time of each ticket, dependency graph, resource assignment and working hours calendar. Just as it happens in any minimally sane Gantt chart project management tool. To enter this information by hand and to keep it up-to-date manually as the project evolves is insane waste of time. Is there a way to generate Gantt chart from the set of Redmine tickets without filling in all this information manually? (Solutions involving data export + import in sane tool or involving existing plugins are perfectly acceptable.)

• SQL SERVER – Storing Variable Values in Temporary Array or Temporary List

  - by pinaldave

  SQL Server does not support arrays or a dynamic length storage mechanism like list. Absolutely there are some clever workarounds and few extra-ordinary solutions but everybody can;t come up with such solution. Additionally, sometime the requirements are very simple that doing extraordinary coding is not required. Here is the simple case. Let us say here are the values: a, 10, 20, c, 30, d. Now the requirement is to store them in a array or list. It is very easy to do the same in C# or C. However, there is no quick way to do the same in SQL Server. Every single time when I get such requirement, I create a table variable and store the values in the table variables. Here is the example: For SQL Server 2012: DECLARE @ListofIDs TABLE(IDs VARCHAR(100)); INSERT INTO @ListofIDs VALUES('a'),('10'),('20'),('c'),('30'),('d'); SELECT IDs FROM @ListofIDs; GO When executed above script it will give following resultset. Above script will work in SQL Server 2012 only for SQL Server 2008 and earlier version run following code. DECLARE @ListofIDs TABLE(IDs VARCHAR(100), ID INT IDENTITY(1,1)); INSERT INTO @ListofIDs SELECT 'a' UNION ALL SELECT '10' UNION ALL SELECT '20' UNION ALL SELECT 'c' UNION ALL SELECT '30' UNION ALL SELECT 'd'; SELECT IDs FROM @ListofIDs; GO Now in this case, I have to convert numbers to varchars because I have to store mix datatypes in a single column. Additionally, this quick solution does not give any features of arrays (like inserting values in between as well accessing values using array index). Well, do you ever have to store temporary multiple values in SQL Server – if the count of values are dynamic and datatype is not specified early how will you about storing values which can be used later in the programming.

• Regarding sprite design and resolution for tablets and phones

  - by Dimitris P.

  I am about to start working on a game for android devices, in my spare time, to get familiar with android development. I'm more interested in using the best practices possible than getting a quick result, and that is why I need some guidance regarding graphics. I think the game is going to be fully sprite based. Everything is going to be in .bmp form, or something similar, and my question is: Should I design the sprites in a small resolution (ie for phone screens) and scale them up to fit into larger screens (tablet screens), should I do it vice-versa or should I consider a completely different approach? Would designing a different set of sprites for each of the most used resolution settings be worth it or are there simpler solutions to the problem with fewer drawbacks than the ones I mentioned above? (If I follow the first approach, for example, the larger the screen the worse the graphics will get, since every pixel of the original drawing will cover several pixels on the screen). Is there a standard approach for dealing with this kind of problems? If you need me to be more detailed or more clear about something I mentioned (or forgot to) please don't hesitate to ask. Also, excuse me for any inaccurate use of the English language. Thank you in advance for your input.

• isometric drawing order with larger than single tile images - drawing order algorithm?

  - by Roger Smith

  I have an isometric map over which I place various images. Most images will fit over a single tile, but some images are slightly larger. For example, I have a bed of size 2x3 tiles. This creates a problem when drawing my objects to the screen as I get some tiles erroneously overlapping other tiles. The two solutions that I know of are either splitting the image into 1x1 tile segments or implementing my own draw order algorithm, for example by assigning each image a number. The image with number 1 is drawn first, then 2, 3 etc. Does anyone have advice on what I should do? It seems to me like splitting an isometric image is very non obvious. How do you decide which parts of the image are 'in' a particular tile? I can't afford to split up all of my images manually either. The draw order algorithm seems like a nicer choice but I am not sure if it's going to be easy to implement. I can't solve, in my head, how to deal with situations whereby you change the index of one image, which causes a knock on effect to many other images. If anyone has an resources/tutorials on this I would be most grateful.

• An Interesting Perspective on Oracle's Mobile Strategy

  - by Carlos Chang

  Oracle’s well known for being an acquisitive company. On average, I think we acquire about 1 company a month. (don’t quote me, I didn't run the numbers)  With all the excitement around mobile, mobile and wait for it… mobile, well, you know...what' s up with that? Well, just to be clear and quote Schultz from Hogan's Heroes "I know nothing! Nothing! "  But I did recently run across this blog by Kevin Benedict over at mobileenterprisestrategies.com covering this very topic, Oracle Mobility Emerges Prepared for the Future,  a little (fair use) snippet here:"History, however, may reward Oracle's patience.  While veteran mobile platform vendors (including SAP) have struggled to keep up with the fast changing market, R&D investment requirements, the fickle preferences of mobile developers, and the emergence of cloud-based mobile services, Oracle has kept their focus on supporting mobile developers with integration services and tools that extend their solutions out to mobile apps.”It’s an interesting read, and I would encourage you to check it out here.   BTW, if you’re a Twitter user, follow our new account @OracleMobile To the first ten thousand followers, I bequeath you my sincere virtual thanks and gratitude. :)  For the dedicated mobile blog, go to blogs.oracle.com/mobile.
