• How do I fix postfix TLS?

  - by Savanni D'Gerinel

  STARTTLS was working with my system earlier today. Without me altering the system in any way, it spontaneously broke. I've now been trying to fix it for a couple of hours, to no success. When I connect to the server, this is what I get: savanni@Orolo:~$ telnet apps.savannidgerinel.com 25 Trying 129.121.182.135... Connected to apps.sasavanni@Orolo:~$ telnet apps.savannidgerinel.com 25 Trying 129.121.182.135... Connected to apps.savannidgerinel.com.

Okay, obviously STARTTLS isn't present in this list. So I've been digging through my configuration files and working through the tutorials again, and that has done me no good at all. Here's my tls-related configuration: smtp_tls_CAfile = /etc/ssl/certs/savannidgerinel_com_CA.pem smtp_tls_cert_file = /etc/ssl/certs/apps.savannidgerinel.com.pem smtp_tls_key_file = /etc/ssl/private/apps.savannidgerinel.com.key.pem smtp_tls_security_level = may smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_tls_CAfile = /etc/ssl/certs/savannidgerinel_com_CA.pem smtpd_tls_cert_file = /etc/ssl/certs/apps.savannidgerinel.com.pem smtpd_tls_key_file = /etc/ssl/private/apps.savannidgerinel.com.key.pem smtpd_tls_loglevel = 3 smtpd_tls_received_header = yes smtpd_tls_security_level = may smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache tls_random_source = dev:/dev/urandom All of the certificate files are present, the server private key is present, the server CA is present, and the smtpd_scache.db and smtp_scache.db files are both present. All are accessible to the postfix user. Speaking of which, here are the processes running: savanni@apps:/var/lib/postfix$ ps aux | grep postfix root 3525 0.0 0.1 25112 1680 ?

• How to Modify a Signature for Use in Plain Text Emails in Outlook 2013

  - by Lori Kaufman

  If you’ve created a signature with an image, links, text formatting, or special characters, the signature will not look the same in plain text formatted emails as it does in HTML format. As the name suggests, Plain Text does not support any type of formatting. For example, if you include an image in your signature, as shown below, the plain text version will be blank. Active links in HTML signatures will be converted to just the text of the link in plain text emails. The How-To Geek link in the image below will become simply How-To Geek and will look like the rest of the text in the signature. The same thing is true in the following example. The active links are stripped from the text. The picture of the envelope that was inserted using the Wingdings font will only display as the plain text character associated with it. There are times you may need to send email in Plain Text format, but still include your signature. You can edit the plain text version of your signature to make it look good in plain text emails by manually editing the text file. To do this, click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. In the Compose messages section, press and hold the Ctrl key and click the Signatures button. This opens the Signatures folder containing the files used to insert signatures into emails. The .txt file version of each signature is used when inserting a signature into a plain text email. Double-click on a .txt file for the signature you want to edit to open it in Notepad, or your default text editor. Notice that the links on “How-To Geek” and “Email me” are gone and the envelope typed using the Wingdings font was converted to an “H.” Edit the text file to remove extra characters, replace images, and provide full web and email links. Save the text file. Create a new mail message and select the edited signature, if it’s not the default signature for the current email account. To convert the email to plain text, click the Format Text tab and click Plain Text in the Format section. The Microsoft Outlook Compatibility Checker displays telling you that Formatted text will become plain text. Click Continue. The HTML version of your signature is converted to the plain text version. NOTE: You should make a backup of the .txt signature file you edited, as this file will change again when you change your signature in the Signature Editor.

• Azure Service Bus - Authorization failure

  - by Michael Stephenson

  I fell into this trap earlier in the week with a mistake I made when configuring a service to send and listen on the azure service bus and I thought it would be worth a little note for future reference as I didnt find anything online about it.  After configuring everything when I ran my code sample I was getting the below error. WebHost failed to process a request.Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/28316044Exception: System.ServiceModel.ServiceActivationException: The service '/-------/BrokeredMessageService.svc' cannot be activated due to an exception during compilation.  The exception message is: Generic: There was an authorization failure.

• LCM says Smart List import is complete but actually its not...Here are probable reasons

  - by RahulS

  First of all some basics of smart list: Administrators use Smart Lists to create custom drop-down lists that users access from data form cells. When clicking in cells whose members are associated with a Smart List (as a member property), users select items from drop-down lists instead of entering data. Users cannot type in cells that contain Smart Lists. Smart Lists display in cells as down arrows that expand when users click into the cells. Below link will give you more information on Smart Lists: http://download.oracle.com/docs/cd/E17236_01/epm.1112/hp_admin/enum_pg.html I got a simple query today, "The LCM process generates and indicates a status of "Complete", however, the 3,018 records do not appear in the Planning application. No error exists in the log to identify the problem." Things which can be checked in this case: 1. Spaces are not allowed in the Entry Name, 2. Spaces are allowed in the Entry Label, 3. The name must start with an alpha character or underscore, 4. Valid characters for the remaining part of the name must be alpha, numeric, or an underscore, 5. Enter a name that is unique within the smart list, 6. I am not sure about the limits but I have seen 22,000 members loaded fine, 7. ID for every entry should be unique,  8. IDs need not to be consecutive, Ex: It was go from 1 to 100 then 500 to 900 then 1900 to 4500 etc. While import .xml file using LCM there were no errors in the foundation and LCM migration logs, but when checked in the HyS9PlanningSysErr.log, few errors were found:Ex: The name Data_Coord_(Prod)_ACS is invalid, The name Sr_Dir_b+Medcd_Gvt_Rel_Sls_Mkt is invalid, The name entered is invalid. Enter a name that is unique within the smart list, Also, we can Load Smart List dimensions and Smart List dimension entries using the /DS:HSP_SMARTLISTS parameter in outlineload utility: OutlineLoad /A:acpt /U:admin /M /I:c:/smartlist_create1.csv /DS:HSP_SMARTLISTS /L:c:/OutlineLogs/outlineLoad.log /X:c:/OutlineLogs/outlineLoad.exc SmartList Name, Operation, Label, Display Order, Missing Label, Use Form Missing Label, Entry ID, Entry Name, Entry Label SL1,addsmartlist,SL1Label,,,,,, SL1,addEntry,,,,,,entry1,entrylabel1 SL1,addEntry,,,,,,entry2,entrylabel2 Cheers..!!!

• How to access files on a drive from an older system, mounted in a new system?

  - by David Thomas

  I've recently built a new system, after a rather large physical injury was sustained by my previous system (a precarious balance, and gravity, were not a happy mix). Surprisingly the /home drive of that system appears to have more-or-less survived the trauma. However... I decided to use a fresh drive for / (and swap) partition(s), and another fresh drive for the new /home. Now that's working, I decided to install the old /home drive (that I had assumed until now would be entirely dead and without capacity for use) into the new system to recover the files and data (so far as is possible). At this point I've run into a snag: I have no idea how to go about this (with Windows it was relatively easy, the new drive would be the latest character of the alphabet, and go from there). With 'disk utility' (System - Administration - Disk Utitlity) I've worked out which drive it is (/dev/sda) but clicking on 'mount' produces an error: 1: helper failed with: mount: according to mtab, /dev/sdb1 is already mounted on / mount failed ...if it is mounted on / I can't see it. I'm also moderately confused by the disk (device /dev/sda) being referred to as /dev/sdb1. Any and all insights would be incredibly welcome (I've already voted for: Idea #9063: New internal hard drives default automount at Brainstorm). Edited in response to Roland's request for a screenshot of disk utility: Details (so far as I know them): 40GB disk is / and swap, 1.0 TB Samsung is /home 1.0 TB Hitachi is from the old system (and was the old /home drive). Output from sudo fdisk -l pasted below: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000bef00 Device Boot Start End Blocks Id System /dev/sda1 1 121601 976760001 83 Linux Disk /dev/sdb: 40.0 GB, 40018599936 bytes 255 heads, 63 sectors/track, 4865 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00037652 Device Boot Start End Blocks Id System /dev/sdb1 * 1 4742 38084608 83 Linux /dev/sdb2 4742 4866 993281 5 Extended /dev/sdb5 4742 4866 993280 82 Linux swap / Solaris Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e8d46 Device Boot Start End Blocks Id System /dev/sdc1 1 121602 976760832 83 Linux

• Simplifying C++11 optimal parameter passing when a copy is needed

  - by Mr.C64

  It seems to me that in C++11 lots of attention was made to simplify returning values from functions and methods, i.e.: with move semantics it's possible to simply return heavy-to-copy but cheap-to-move values (while in C++98/03 the general guideline was to use output parameters via non-const references or pointers), e.g.: // C++11 style vector<string> MakeAVeryBigStringList(); // C++98/03 style void MakeAVeryBigStringList(vector<string>& result); On the other side, it seems to me that more work should be done on input parameter passing, in particular when a copy of an input parameter is needed, e.g. in constructors and setters. My understanding is that the best technique in this case is to use templates and std::forward<>, e.g. (following the pattern of this answer on C++11 optimal parameter passing): class Person { std::string m_name; public: template <class T, class = typename std::enable_if < std::is_constructible<std::string, T>::value >::type> explicit Person(T&& name) : m_name(std::forward<T>(name)) { } ... }; A similar code could be written for setters. Frankly, this code seems boilerplate and complex, and doesn't scale up well when there are more parameters (e.g. if a surname attribute is added to the above class). Would it be possible to add a new feature to C++11 to simplify code like this (just like lambdas simplify C++98/03 code with functors in several cases)? I was thinking of a syntax with some special character, like @ (since introducing a &&& in addition to && would be too much typing :) e.g.: class Person { std::string m_name; public: /* Simplified syntax to produce boilerplate code like this: template <class T, class = typename std::enable_if < std::is_constructible<std::string, T>::value >::type> */ explicit Person(std::string@ name) : m_name(name) // implicit std::forward as well { } ... }; This would be very convenient also for more complex cases involving more parameters, e.g. Person(std::string@ name, std::string@ surname) : m_name(name), m_surname(surname) { } Would it be possible to add a simplified convenient syntax like this in C++? What would be the downsides of such a syntax?

• In a state machine, is it a good idea to separate states and transitions?

  - by codablank1

  I have implemented a small state machine in this way (in pseudo code): class Input {} class KeyInput inherits Input { public : enum { Key_A, Key_B, ..., } } class GUIInput inherits Input { public : enum { Button_A, Button_B, ..., } } enum Event { NewGame, Quit, OpenOptions, OpenMenu } class BaseState { String name; Event get_event (Input input); void handle (Event e); //event handling function } class Menu inherits BaseState{...} class InGame inherits BaseState{...} class Options inherits BaseState{...} class StateMachine { public : BaseState get_current_state () { return current_state; } void add_state (String name, BaseState state) { statesMap.insert(name, state);} //raise an exception if state not found BaseState get_state (String name) { return statesMap.find(name); } //raise an exception if state or next_state not found void add_transition (Event event, String state_name, String next_state_name) { BaseState state = get_state(state_name); BaseState next_state = get_state(next_state_name); transitionsMap.insert(pair<event, state>, next_state); } //raise exception if couple not found BaseState get_next_state(Event event, BaseState state) { return transitionsMap.find(pair<event, state>); } void handle(Input input) { Event event = current_state.get_event(input) current_state.handle(event); current_state = get_next_state(event, current_state); } private : BaseState current_state; map<String, BaseState> statesMap; //map of all states in the machine //for each couple event/state, this map stores the next state map<pair<Event, BaseState>, BaseState> transitionsMap; } So, before getting the transition, I need to convert the key input or GUI input to the proper event, given the current state; thus the same key 'W' can launch a new game in the 'Menu' state or moving forward a character in the 'InGame' state; Then I get the next state from the transitionsMap and I update the current state Does this configuration seem valid to you ? Is it a good idea to separate states and transitions ? And I have some kind of trouble to represent a 'null state' or a 'null event'; What initial value can I give to the current state and which one should be returned by get_state if it fails ?

• Sql Table Refactoring Challenge

  Ive been working a bit on cleaning up a large table to make it more efficient.  I pretty much know what I need to do at this point, but I figured Id offer up a challenge for my readers, to see if they can catch everything I have as well as to see if Ive missed anything.  So to that end, I give you my table: CREATE TABLE [dbo].[lq_ActivityLog]( [ID] [bigint] IDENTITY(1,1) NOT NULL, [PlacementID] [int] NOT NULL, [CreativeID] [int] NOT NULL, [PublisherID] [int] NOT NULL, [CountryCode] [nvarchar](10) NOT NULL, [RequestedZoneID] [int] NOT NULL, [AboveFold] [int] NOT NULL, [Period] [datetime] NOT NULL, [Clicks] [int] NOT NULL, [Impressions] [int] NOT NULL, CONSTRAINT [PK_lq_ActivityLog2] PRIMARY KEY CLUSTERED ( [Period] ASC, [PlacementID] ASC, [CreativeID] ASC, [PublisherID] ASC, [RequestedZoneID] ASC, [AboveFold] ASC, [CountryCode] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY] And now some assumptions and additional information: The table has 200,000,000 rows currently PlacementID ranges from 1 to 5000 and should support at least 50,000 CreativeID ranges from 1 to 5000 and should support at least 50,000 PublisherID ranges from 1 to 500 and should support at least 50,000 CountryCode is a 2-character ISO standard (e.g. US) and there is a country table with an integer ID already.  There are < 300 rows. RequestedZoneID ranges from 1 to 100 and should support at least 50,000 AboveFold has values of 1, 0, or 1 only. Period is a date (no time). Clicks range from 0 to 5000. Impressions range from 0 to 5000000. The table is currently write-mostly.  Its primary purpose is to log advertising activity as quickly as possible.  Nothing in the rest of the system reads from it except for batch jobs that pull the data into summary tables. Heres the current information on the database tables size: Design Goals This table has been in use for about 5 years and has performed very well during that time.  The only complaints we have are that it is quite large and also there are occasionally timeouts for queries that reference it, particularly when batch jobs are pulling data from it.  Any changes should be made with an eye toward keeping write performance optimal  while trying to reduce space and improve read performance / eliminate timeouts during read operations. Refactor There are, I suggest to you, some glaringly obvious optimizations that can be made to this table.  And Im sure there are some ninja tweaks known to SQL gurus that would be a big help as well.  Ill post my own suggested changes in a follow-up post for now feel free to comment with your suggestions. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  Im trying to get my enemies to follow my main-character of the game (2D), but for some reason the game starts lagging like crazy when I do it the way I want to do it, and the following-part dosnt work 100% either, its just 1/24 enemies that comes to my sprite, the other 23 move towards it but stay at a certain point. Might be a poor explenation but dont know how else to put it. Code for moving my enemies: private int enemyX(){ int x = 0; for (int i = 0; i < enemies.size(); i++){ if (controls.pointerPosition.x > enemies.get(i).getX()){//pointerPosition is the position of my main-sprite. x = 5; } else{ x=-5; } Log.d(TAG, "happyX HERE: " + controls.pointerPosition.x); Log.d(TAG, "enemyX HERE: " + enemies.get(i).getX()); } return x; } private int enemyY(){ int y = 0; for (int i = 0; i < enemies.size(); i++){ if (controls.pointerPosition.y > enemies.get(i).getY()){ y = 5; } else{ y=-5; } } return y; } I send it to the update-method in my Enemy-class: private void drawEnemy(Canvas canvas){ addEnemies(); // a method where I add enemies to my arrayList, no parameters except bitmap. for(int i = 0; i < enemies.size(); i++){ enemies.get(i).update(enemyX(), enemyY()); } for(int i = 0; i < enemies.size(); i++){ enemies.get(i).draw(canvas); } } and finally, the update-method itself, located in my Enemy-class: public void update(int velX, int velY) { x += velX; //sets x before I draw y += velY; //sets y before I draw currentFrame = ++currentFrame % BMP_COLUMNS; } So can any1 figure out why it starts lagging so much and how I can fix it? Thanks for your time!

• Jitter during wall collisions with Bullet Physics: contact/penetration tolerance?

  - by Niriel

  I use the bullet physics engine through Panda3d. My scene is still very simple, think 'Wolfenstein3d': tile-based, walls are solid cubes. I expect walls to block the player, and I expect the player to slide along the walls in case of non-normal incidence. What I get is what I expect, with one difference: there is some jitter. If I try to force myself into the wall, then I see the frames blinking quickly between two positions. These differ by about 0.04 units of distance, which corresponds to 4 cm in my game. I noticed a 4 cm elsewhere: the bottom of my player capsule is 4 cm below ground, when at rest. Does that mean that there is somewhere in the Bullet engine a default 0.04-units-long tolerance to differentiate contact from collision? If so, what should I do ? Should I change the scale of my game so that these 0.04 units correspond to 0.4 cm, making the jitter ten times smaller? Or can I ask bullet to change its tolerance to a smaller value? Edit This is the jitter I get: 6.155 - 6.118 = 0.036 LPoint3f(0, 6.11694, 0.835) LPoint3f(0, 6.15499, 0.835) LPoint3f(0, 6.11802, 0.835) LPoint3f(0, 6.15545, 0.835) LPoint3f(0, 6.11817, 0.835) LPoint3f(0, 6.15726, 0.835) LPoint3f(0, 6.11876, 0.835) LPoint3f(0, 6.15911, 0.835) LPoint3f(0, 6.11937, 0.835) I found a setMargin method. I set it to 5 mm both on the BoxShape for the walls and on the Capsule shape for the player. It still jitters by about 35 mm as illustrated by this log (11.117 - 11.082 = 0.035): LPoint3f(0, 11.0821, 0.905) LPoint3f(0, 11.1169, 0.905) LPoint3f(0, 11.082, 0.905) LPoint3f(0, 11.117, 0.905) LPoint3f(0, 11.082, 0.905) LPoint3f(0, 11.117, 0.905) LPoint3f(0, 11.0821, 0.905) LPoint3f(0, 11.1175, 0.905) LPoint3f(0, 11.0822, 0.905) LPoint3f(0, 11.1178, 0.905) LPoint3f(0, 11.0823, 0.905) LPoint3f(0, 11.1183, 0.905) The margin on the capsule did change my penetration with the floor though, I'm a bit higher (0.905 instead of 0.835). However, it did not change anything when colliding with the walls. How can I make the collisions against the walls less jittery? Edit, the day after: After more investigation, it appears that dynamic objects behave well. My problem comes from the btKinematicCharacterController that I use for moving my character; that stuff is totally bugged, according to the whole Internet :/.

• Professional immigration

  - by etranger

  Hello all, Does anyone here have a practical advice on professional relocation from Russia to Europe? The reasons behind making such a decision are far beyond the subject, perhaps, so I'll stick to the practical part. Having done some of the "common stuff" for finding a job, I am now facing two serious problems: I am a "dual-class" person, with university degree in marketing, and multiple years of self-studied computer competence (hence my writing here). Have professional experience in both areas. I don't currently hold a European work permit. From what I can see, this results in normal HR person throwing out my CV as either being "overqualified" or "too much trouble with making the permit". I do have the skills and character to start my own business, but it requires start-up capital that I don't have, over the last years I had to pay high bills for medical treatment of my family member, who had deceased. Now, I'm almost out of debts. As you can probably guess, English is not a problem, and I'm open to new languages, but first steps of entering the market, or the society, is the problematic part. I live close to Norway, and am trying to get some professional contacts there, but it hasn't got me any practical perspective so far. Any advice is greatly appreciated. EDIT: I am currently making my living off web site development, and occasional consulting services both in IT and marketing. For purely geographic reasons I'm dealing with clients that reside in the same city where I live, pop. 350 000. Being quite local, market requirements for web sites are simple and stable — clients need to control navigation, write articles in a word-like editor, upload illustrations and place ad banners, all with no additional programming. As many web developers do, I'm using my own content management system that fits these expectations. I have also started developing a newer version of this system that has better support for international environments, but I'm too distant from the real market demand in Europe to speak of the right track here. Technically it's based on php/mysql and uses xslt for templating. It allows for quick website deployment, and has architectural neatness, lack of which made me abandon similar opensource solutions (Joomla and the like). Deploying time from rasterized design proofs is normally under 6-8 working hours, don't know how that compares to the world practice. EDIT 2: Can anyone share what Norwegian (Scandinavian) web solutions market currently demands?

• How to keep a data structure synchronized over a network?

  - by David Gouveia

  Context In the game I'm working on (a sort of a point and click graphic adventure), pretty much everything that happens in the game world is controlled by an action manager that is structured a bit like: So for instance if the result of examining an object should make the character say hello, walk a bit and then sit down, I simply spawn the following code: var actionGroup = actionManager.CreateGroup(); actionGroup.Add(new TalkAction("Guybrush", "Hello there!"); actionGroup.Add(new WalkAction("Guybrush", new Vector2(300, 300)); actionGroup.Add(new SetAnimationAction("Guybrush", "Sit")); This creates a new action group (an entire line in the image above) and adds it to the manager. All of the groups are executed in parallel, but actions within each group are chained together so that the second one only starts after the first one finishes. When the last action in a group finishes, the group is destroyed. Problem Now I need to replicate this information across a network, so that in a multiplayer session, all players see the same thing. Serializing the individual actions is not the problem. But I'm an absolute beginner when it comes to networking and I have a few questions. I think for the sake of simplicity in this discussion we can abstract the action manager component to being simply: var actionManager = new List<List<string>>(); How should I proceed to keep the contents of the above data structure syncronized between all players? Besides the core question, I'm also having a few other concerns related to it (i.e. all possible implications of the same problem above): If I use a server/client architecture (with one of the players acting as both a server and a client), and one of the clients has spawned a group of actions, should he add them directly to the manager, or only send a request to the server, which in turn will order every client to add that group? What about packet losses and the like? The game is deterministic, but I'm thinking that any discrepancy in the sequence of actions executed in a client could lead to inconsistent states of the world. How do I safeguard against that sort of problem? What if I add too many actions at once, won't that cause problems for the connection? Any way to alleviate that?

• Investment scheme for a PC game the project

  - by Alex Kamen

  Good day everyone, I am working on a PC game project that has 3 phases planned, micro, macro and mmo versions [if confused, see a brief description at the bottom]. I have found a potential investor for the micro version of the game, but naturally, he requested a detailed plan of how the game will pay back. And the problem is that micro version itself is not supposed to be monetized much, other than some ads and limited in-game currency utilization. The idea is that with this combat demo already at hand, it should be possible to get a really large enough investment (millions of dollars) and use it to pay back the initial small one (thousands of dollars) and take the project into macro phase, which will really make profit. This way, everybody is going to win, provided that I can deliver the end-product. Yet while I am confident of that both the conception of the macro and the real game-play of the micro versions are going to be appealing, I don’t know how to obtain any guarantee of that I will be able to get funded once I have the prototype ready. And without that, I won’t receive the funds for the prototype in the first place! To summarize, my question is: how to figure out my future possibilities of getting funded once I have combat demo out, basically “whom to write to and what”. Ideally, I would like some sort of a preliminary agreement with a game publisher, something that would basically state “If the developer provides the product in time and in quality corresponding to the specifications given, the publisher guarantees to allocate funds for distribution and further development, thereby acquiring the right to X part of all future profits”. Does this sound sane? It’s just that I don’t want to sell all of my rights out straight away by taking a big outside investment while the project is in such early stage. I would appreciate if you would share your thoughts on this kind of scheme, and be sure to ask questions as I am sure I must have forgotten to mention a ton of important things, like the fact that initial funds are going to be spent on outsourcing (living in Siberia is really just great). [here’s a brief outline of what each version will feature] [micro] 1) turn based tactical combat rules 2) character development 3) arena/tournament system [macro] 4) ai-ruled dynamic interactive worlds 5) global map adventuring 6) strategic rpg + god simulator gameplay [mmo] 7) Persistent worlds system 8) Social structures system (“guilds/clans”) 9) god-simulation on the mmo scale P.S. Obviously, these features are incremental, so that mmo version has all 9.

• C Minishell Command Expansion Printing Gibberish

  - by Optimus_Pwn

  I'm writing a unix minishell in C, and am at the point where I'm adding command expansion. What I mean by this is that I can nest commands in other commands, for example: $> echo hello $(echo world! ... $(echo and stuff)) hello world! ... and stuff I think I have it working mostly, however it isn't marking the end of the expanded string correctly, for example if I do: $> echo a $(echo b $(echo c)) a b c $> echo d $(echo e) d e c See it prints the c, even though I didn't ask it to. Here is my code: msh.c - http://pastebin.com/sd6DZYwB expand.c - http://pastebin.com/uLqvFGPw I have a more code, but there's a lot of it, and these are the parts that I'm having trouble with at the moment. I'll try to tell you the basic way I'm doing this. Main is in msh.c, here it gets a line of input from either the commandline or a shellfile, and then calls processline (char *line, int outFD, int waitFlag), where line is the line we just got, outFD is the file descriptor of the output file, and waitFlag tells us whether or not we should wait if we fork. When we call this from main we do it like this: processline (buffer, 1, 1); In processline, we allocate a new line: char expanded_line[EXPANDEDLEN]; We then call expand, in expand.c: expand(line, expanded_line, EXPANDEDLEN); In expand, we copy the characters literally from line to expanded_line until we find a $(, which then calls: static int expCmdOutput(char *orig, char *new, int *oldl_ind, int *newl_ind) orig is line, and new is expanded line. oldl_ind and newl_ind are the current positions in the line and expanded line, respectively. Then we pipe, and recursively call processline, passing it the nested command(for example, if we had "echo a $(echo b)", we would pass processline "echo b"). This is where I get confused, each time expand is called, is it allocating a new chunk of memory EXPANDEDLEN long? If so, this is bad because I'll run out of stack room really quickly(in the case of a hugely nested commandline input). In expand I insert a null character at the end of the expanded string, so why is it printing past it? If you guys need any more code, or explanations, just ask. Secondly, I put the code in pastebin because there's a ton of it, and in my experience people don't like it when I fill up several pages with code. Thanks.

• Turn-Based RPG Battle Instance Layout For Larger Groups

  - by SoulBeaver

  What a title, eh? I'm currently designing a videogame; a turn-based RPG like Final Fantasy (because everybody knows Final Fantasy). It's a 2D sprite game. These are my ideas for combat: -The player has a group of 15 members (main character included) -During battle, five of the group are designated as active, and appear in the battle. -These five may be switched out at leisure, or when one of the five die. -At any time, the Waiting members can cast buffs, be healed by the active members, or perform special attacks. -Battles should contain 10+ monsters at least. I'm aiming for 20, but I'm not sure if that's possible yet. -Battles should feel larger than normal due to the interaction of Waiting members, active members and the increased amount of monsters per battle. -The player has two rows in which to put the Active members: front and back. -Depending on the implementation, I might allow comboing of player attacks and skills. These are just design ideas, so beware! I have not been able to test this out yet- I have no idea yet if any of these ideas bunched together will make for a compelling game. What sounds good on paper doesn't necessarily have to be good in practice! What I'm asking now is how to create the layout for this. My starting point are the battles in Final Fantasy VI, with up to 5-6 monsters on the left and the characters on the right- monsters on both sides if it's a pincer attack. However, this view would not work feasible with my goal of 20 monsters and 5 characters. All the monsters on the left would appear cluttered unless I scale them far far back. If I create a pincer-like map, then there would be no real pincer-attack possible. If I space the monsters out I force the player to scroll the screen- a game mechanic I've come across and not enjoyed imho. My question is: does anybody have any layouts or guides for designing battle maps in turn-based RPGs, especially with a larger number of enemies taken into consideration? How should it look? I am not asking for specific combat mechanics, just the layout for the moment.

• Why my collision detection is not accurate?

  After trying and trying, I still cannot understand why the leg of character exceeds the wall but no clipping issue when I hit the wall from below. How should I fix it to make him standstill on the wall? void initPlayer() { // Create texture. hr = D3DXCreateTextureFromFileEx(d3dDevice, "player.png", 169, 44, D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(255, 255, 255), NULL, NULL, &player); playerRect.left = playerRect.top = 0; playerRect.right = 29; playerRect.bottom = 36; playerDest.X = 0; playerDest.Y = 564; playerDest.length = playerRect.right - playerRect.left; playerDest.height = playerRect.bottom - playerRect.top; } void initBox() { hr = D3DXCreateTextureFromFileEx(d3dDevice, "brock.png", 330, 132, D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(255, 255, 255), NULL, NULL, &box); boxRect.left = 33; boxRect.top = 0; boxRect.right = 63; boxRect.bottom = 30; boxDest.X = boxDest.Y = 300; boxDest.length = boxRect.right - boxRect.left; boxDest.height = boxRect.bottom - boxRect.top; } bool spriteCollide(Entity player, Entity target) { float left1, left2; float right1, right2; float top1, top2; float bottom1, bottom2; left1 = player.X; left2 = target.X; right1 = player.X + player.length; right2 = target.X + target.length; top1 = player.Y; top2 = target.Y; bottom1 = player.Y + player.height; bottom2 = target.Y + target.height; if (bottom1 < top2) return false; if (top1 > bottom2) return false; if (right1 < left2) return false; if (left1 > right2) return false; return true; } void collideWithBox() { if ( spriteCollide(playerDest, boxDest) && keyArr[VK_UP]) //playerDest.Y += 50; playerDest.Y = boxDest.Y + boxDest.height; else if ( spriteCollide(playerDest, boxDest) && !keyArr[VK_UP]) playerDest.Y = boxDest.Y - boxDest.height; }

• core.* files eating up server space (~50MB)

  - by skytreader

  I'm renting server space from someone and, upon logging in my control panel after quite sometime, noticed an abnormal spike (~50MB) in the disk usage. Upon investigating, I found a lot of core.* files scattered around my public_html directory. Each one is more than 5MB in size but no more than 6MB. The * part is all numbers (in programming regex, that should be core\.\d+). I downloaded one and checked the contents. There was a lot of balderdash characters (NUL mostly, but also a scattering of ETB, ETX, STX) but there's this block of readable text which says: This text is part of the internal format of your mail folder, and is not a real message. It is created automatically by the mail system software. If deleted, important folder data will be lost, and it will be re-created with the data reset to initial values. Pretty self-explanatory. A few blocks above the text are some more readable messages that look like logs but is sandwiched in between non printable characters. I've extracted some below. Scan not valid for mh mailboxes Bogus character 0x%x in news state Can't rewrite news state %.80s Error closing backup news state %.80s No state for newsgroup %.80s found Now, a few concerns: Am I under attack? The messages seem to be about my webmail but I don't use my personal webmail that much---only for a vanity email address and an inbox for an outdated comments system. However, lately, I seem to notice a spike in the spam for my vanity mail. (Note: the comments system is covered by a captcha but every now and then some get through. My vanity email has a spam filter but it isn't as good as I'd like). Next, if this is a feature, can I turn it off? Is it advisable to? I've only 150MB so you see why I'm fretting over a 50MB spike. Some final details: my only server-side scripts are in PHP. The directory which accumulated the most number of these core files is the one containing the Wordpress-managed subdomain of my site. I manage my server through CPanel. Lastly, I decided to delete this files and after some checking nothing seems amiss in my websites nor in my mail. They are indeed the ones responsible for the ~50MB spike as my disk space usage is back to expected.

• How to deal with MySQL Connector/ODBC error "Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'"

  - by user12653020

  I am sure many users run into a mysterious problem when perfectly working ODBC configurations started failing with errors like: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' The above error message might be preceded with something like [nxDc[yQ]. At the same time odbc.ini specifies in its DSN different SOCKET=/tmp/mysql.sock or a TCP connection SERVER=<remote_host_or_ip>. The question is, what had happened that the ODBC driver started to ignore the DSN options? The clue lies in the corrupted string [nxDc[yQ], which actually was [UnixODBC][MySQL] with each 2nd symbol removed. This is the case of bad conversion from SQLCHAR to SQLWCHAR. The UnixODBC driver manager took a single-byte character string from the client application and tried to convert it into the wide (multi-byte) characters for the Unicode version of MyODBC driver: Initially the piece of the connection string was represented by 1-byte chars like: [S][E][R][V][E][R][=][m][y][h][o][s][t][;] after the bad conversion to wide chars (commonly 2-byte UTF-16) [SE][RV][ER][=m][yh][os][t;] instead of [S\0][E\0][R\0][V\0][E\0][R\0][=\0][m\0][y\0][h\0][o\0][s\0][t\0][;\0] Naturally, the MyODBC driver could not parse the bad string and tried to use the default connection type (SOCKET) with the default value (/var/lib/mysql/mysql.sock) Now we know what happened, but why it happened? In most cases it happened because of using ODBCManageDataSourcesQ4 utility or its older analog ODBCConfig. When registering ODBC drivers they put lots of additional options and one of these options badly affects the UnixODBC driver manager itself. The solution is simple - remove or comment out the option in odbcinst.ini file (it is empty by default) set for the driver: [MySQL ODBC 5.2.6 Driver] Description    = Driver         = /home/dbs/myodbc526/lib/libmyodbc5w.so Driver64       = /home/dbs/myodbc526/lib/libmyodbc5w.so Setup          = /home/dbs/myodbc526/lib/libmyodbc5S.so Setup64        = /home/dbs/myodbc526/lib/libmyodbc5S.so UsageCount     = 1 CPTimeout      = 0 CPTimeToLive   = 0 IconvEncoding  =  # <--------- remove this line Trace          = TraceFile      = TraceLibrary   = After applying this simple solution (remove the line with IconvEncoding = ) everything came to normal. Prior to removing that line I tried putting different encoding names there, but the result was not good, so I really don't know how to properly use it. Unfortunately, UnixODBC manuals say nothing about it. Therefore, removing this option was the only way to get things done.

• How can I tweak this A* search pathfinding algorithm to handle different terrain movement values?

  - by user422318

  I'm creating a 2D map-based action game with similar interaction design as Diablo II. In other words, the player clicks around a map to move their player. I just finished player movement and am moving on to pathfinding. In the game, enemies should charge the player's character. There are also five different terrain types that give different movement bonuses. I want the AI to take advantage of these terrain bonuses as they try to reach the player. I was told to check out the A* search algorithm (http://en.wikipedia.org/wiki/A*_search_algorithm). I'm doing this game in HTML5 and JavaScript, and found a version in JavaScript: http://www.briangrinstead.com/blog/astar-search-algorithm-in-javascript I'm trying to figure out how to tweak it though. Below are my ideas about what I need to change. What else do I need to worry about? When I create a graph, I will need to initialize the 2D array I pass in passed on with a traversal of a map that corresponds to the different terrain types. in graph.js: "GraphNodeType" definition needs to be modified to handle the 5 terrain types. There will be no walls. in astar.js: The g and h scoring will need to be modified. How should I do this? in astar.js: isWall() should probably be removed. My game doesn't have walls. in astar.js: I'm not sure what this is. I think it indicates a node that isn't valid to be processed. When would this happen, though? At a high level, how do I change this algorithm from "oh, is there a wall there?" to "will this terrain get me to the player faster than the terrain around me?" Because of time, I'm also debating reusing my Bresenham algorithm for the enemies. Unfortunately, the different terrain movement bonuses won't be used by the AI, which will make the game suck. :/ I'd really like to have this in for the prototype, but I'm not a developer by trade nor am I a computer scientist. :D If you know of any code that does what I'm looking for, please share! Sanity check tips for this are also appreciated.

• StringBuffer behavior in LWJGL

  - by Michael Oberlin

  Okay, I've been programming in Java for about ten years, but am entirely new to LWJGL. I have a specific problem whilst attempting to create a text console. I have built a class meant to abstract input polling to it, which (in theory) captures key presses from the Keyboard object and appends them to a StringBuilder/StringBuffer, then retrieves the completed string after receiving the ENTER key. The problem is, after I trigger the String return (currently with ESCAPE), and attempt to print it to System.out, I consistently get a blank line. I can get an appropriate string length, and I can even sample a single character out of it and get complete accuracy, but it never prints the actual string. I could swear that LWJGL slipped some kind of thread-safety trick in while I wasn't looking. Here's my code: static volatile StringBuffer command = new StringBuffer(); @Override public void chain(InputPoller poller) { this.chain = poller; } @Override public synchronized void poll() { //basic testing for modifier keys, to be used later on boolean shift = false, alt = false, control = false, superkey = false; if(Keyboard.isKeyDown(Keyboard.KEY_LSHIFT) || Keyboard.isKeyDown(Keyboard.KEY_RSHIFT)) shift = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMENU) || Keyboard.isKeyDown(Keyboard.KEY_RMENU)) alt = true; if(Keyboard.isKeyDown(Keyboard.KEY_LCONTROL) || Keyboard.isKeyDown(Keyboard.KEY_RCONTROL)) control = true; if(Keyboard.isKeyDown(Keyboard.KEY_LMETA) || Keyboard.isKeyDown(Keyboard.KEY_RMETA)) superkey = true; while(Keyboard.next()) if(Keyboard.getEventKeyState()) { command.append(Keyboard.getEventCharacter()); } if (Framework.isConsoleEnabled() && Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) { System.out.println("Escape down"); System.out.println(command.length() + " characters polled"); //works System.out.println(command.toString().length()); //works System.out.println(command.toString().charAt(4)); //works System.out.println(command.toString().toCharArray()); //blank line! System.out.println(command.toString()); //blank line! Framework.disableConsole(); } //TODO: Add command construction and console management after that } } Maybe the answer's obvious and I'm just feeling tired, but I need to walk away from this for a while. If anyone sees the issue, please let me know. This machine is running the latest release of Java 7 on Ubuntu 12.04, Mate desktop environment. Many thanks.

• Configuring trace file size and number in WebCenter Content 11g

  - by Kyle Hatlestad

  Lately I've been doing a lot of debugging using the System Output tracing in WebCenter Content 11g.  This is built-in tracing in the content server which provides a great level of detail on what's happening under the hood.  You can access the settings as well as a view of the tracing by going to Administration -> System Audit Information.  From here, you can select the tracing sections to include.  Some of my personal favorites are searchquery,  systemdatabase, userstorage, and indexer.  Usually I'm trying to find out some information regarding a search, database query, or user information.  Besides debugging, it's also very helpful for performance tuning. One of the nice tricks with the tracing is it honors the wildcard (*) character.  So you can put in 'schema*' and gather all of the schema related tracing.  And you can notice if you select 'all' and update, it changes to just a *.   To view the tracing in real-time, you simply go to the 'View Server Output' page and the latest tracing information will be at the bottom. This works well if you're looking at something pretty discrete and the system isn't getting much activity.  But if you've got a lot of tracing going on, it would be better to go after the trace log file itself.  By default, the log files can be found in the <content server instance directory>/data/trace directory. You'll see it named 'idccs_<managed server name>_current.log.  You may also find previous trace logs that have rolled over.  In this case they will identified by a date/time stamp in the name.  By default, the server will rotate the logs after they reach 1MB in size.  And it will keep the most recent 10 logs before they roll off and get deleted.  If your server is in a cluster, then the trace file should be configured to be local to the node per the recommended configuration settings. If you're doing some extensive tracing and need to capture all of the information, there are a couple of configuration flags you can set to control the logs. #Change log size to 10MB and number of logs to 20FileSizeLimit=10485760FileCountLimit=20 This is set by going to Admin Server -> General Configuration and entering them in the Additional Configuration Variables: section.  Restart the server and it should take on the new logging settings.

• How to implement a component based system for items in a web game.

  - by Landstander

  Reading several other questions and answers on using a component based system to define items I want to use one for the items and spells in a web game written in PHP. I'm just stuck on the implementation. I'm going to use a DB schema suggested in this series (part 5 describes the schema); http://t-machine.org/index.php/2007/09/03/entity-systems-are-the-future-of-mmog-development-part-1/ This means I'll have an items table with generic item properties, a table listing all of the components for an item and finally records in each component table used to make up the item. Assuming I can select the first two together in a single query, I'm still going to do N queries for each component type. I'm kind of fine with this because I can cache the data into memcache and check there first before doing any queries. I'll need to build up the items on every request they are used in so the implementation needs to be on the lean side even if they're pulled from memcache. But right there is where I feel confident about implementing a component system for my items ends. I figure I'd need to bring attributes and behaviors into the container from each component it uses. I'm just not sure how to do that effectively and not end up writing a lot of specialized code to deal with each component. For example an AttackComponent might need to know how to filter targets inside of a battle context and also maybe provide an attack behavior. That same item might also have a UsableComponent which allows the item to be used and apply some effect onto a different set of targets filtered differently from the same battle context. Then not every part of an item is an active part, an AttributeBonusComponent might need to only kick in when the item is in an equipped state or when displaying the item details page. Ultimately, how should I bring all of the components together into the container so when I use an item as a weapon I get the correct list of targets? Know when a weapon can also be used as an item? Or to apply the bonuses the item provides to a character object? I feel like I've gone too far down the rabbit hole and I can't grasp onto the simple solution in front of me. (If that makes any sense at all.) Likewise if I were to implement the best answer from here I feel like I'd have a lot of the same questions. How to model multiple "uses" (e.g. weapon) for usable-inventory/object/items (e.g. katana) within a relational database.

• Working with Windows and Unix

  - by user554629

  Beware of new line characters One of the most frequent issues we encounter in Tech Support is the corruption of files that are transferred between Windows and Unix.   The transfer can occur at any stage, but ultimately involves a transfer of a file using an ftp client that is running on Windows;  it could be ftp or filezilla. Windows uses two characters to mark the end of a line in a text file (CR/LF),carriage return, linefeed.   Unix uses a single character (CR). In all situations, it is best to use binary mode transfer for all files, including ascii text files. Common problems: upload a core file from unix to windows using ftp in ascii mode.The file is going to be larger on Windows than Unix.ftp doesn't know if this is a text file with real line-ends, it takes every ascii CR and transmits two ascii characters CR/LF.The core file, tar file, library ... will be corrupted when transferred to Oracle. download a shell script to Windows, and transfer it to Unix using ftpIf the file is edited on Windows, the unix script line-end chars will be doubled.Unix doesn't know how to handle that, and will likely tell you the script is not executable.Why?  The first line of a shell script ( called "sh-bang" ), identifies the command interpreter the unix shell should use for this script.   Common examples:#/bin/sh#/bin/ksh#/bin/bash#/bin/perl#/bin/sh^M    # will not be understood.#/bin/env ksh # special syntax.  Find ksh and run it dos2unix is a common utility found on most unix platforms, that repairs the issue of Windows LineEnd characters in unix script files.   I've written my own flavor of this utility for use in Tech Support and build environments, that is a bit easier to use, and has some nice side-effects. accepts a list of files:   dos2unix *.sh repairs the file in-place.  Doesn't generate a new file you have to name retains the same timestamp;  it is the encoding that changed, not the file content. Here are the versions of dos2unix for each of the environments we work in.They are compressed with gzip, to avoid the ftp ascii transfer trap,and because I am quite limited in the number of files I can upload to this blog.
