  • Application toolkits like QT versus traditional game/multimedia libraries like SFML

    - by Aaron
    I currently intend to use SFML for my next game project. I'll need a substantial GUI though (RPG/strategy-type) so I'll either have to implement my own or try to find an appropriate third party library, which seem to boil down to CEGUI, libRocket, and GWEN. At the same time, I do not anticipate doing that many advanced graphical effects. My game will be 2D and primarily sprite-based with some sprite animations. I've recently discovered that QT applications can have their appearance styled so that they don't have to look like plain OS apps. Given that, I am beginning to consider QT a valid alternative to SFML. I wouldn't have to implement the GUI functionality I'd need, and I may not be taking advantage of SFML's lower-level access anyway. The only drawbacks I can think of immediately are the learning curve for QT and figuring out how to fit game logic inside such a framework after getting used to the input/update/render loop of traditional game libraries. When would an application toolkit like QT be more appropriate for a game than a traditional game or multimedia library like SFML?

  • Input/Output console window in XNA

    - by Will Bagley
    I am currently making a simple game in XNA but am at a point where testing various aspect gets a bit tricky, especially when you have to wait till you have 1000 score to see if your animation is playing correctly etc. Of course i could just edit the starting variable in the code before I launched but I have recently been interested in trying to implement a console style window which can print out values and take input to alter public variables during run-time. I am aware that VS has the immediate window which achieves a similar thing but i would prefer mine is an actual part of the game with the intention that the user may have limited access to it in the future. Some of the key things i have yet to find an answer to after looking around for a while are: how i would support free text entry how i would access variables during runtime how i would edit these variable I have also read about using a property grid from windows form aps (and partially reflection) which looked like it could simplify a lot of things but i am not sure how I would get that running inside my XNA game window or how i would get it to not look out of place (as the visual aspect of is seems to be aimed just for development time viewing). All in all I'm quite open to any suggestions on how to approach this task as currently I'm not sure where to start. Thanks in advance.

  • PHP safe_mode is a pain, looking for advice (Ubuntu 12.04 server, public webserver)

    - by user73279
    Maybe askUbuntu isn't the right forum or I haven't provided the right search query but I haven't seen anything in my searching of askUbuntu on PHP safe_mode. I get lots of Windows Safe Mode and Ubuntu Safe Mode results but not PHP safe_mode. So I keep running into one issue after another regarding PHP safe_mode. (I write a lot of my own PHP code for various site maintenance tools and such.) I know safe_mode is going away in the next version of PHP but I still see a fair amount of advice recommending that you leave it enabled. I've recently consolidated from 3 servers down to 1 and at least one of those old servers had safe_mode disabled without any issues. (The lack of issues may have simply been a matter of good luck.) None of the previous 3 gave me this much trouble so I'm guessing so additional php.ini/PHP safe_mode setting was turned on for the new server. I primarily run WordPress for my websites with a few MediaWiki sites sprinkled in. And I am currently running into an issue using WordPress's auto update feature as it doesn't seem to be able to use fopen. WordPress is not relaying the actual error message to me but since I was just able to update the plugins I'm using this is a safe_mode problem. I've had a lot of safe_mode issues since consolidating to this new server. Long story short, the advice I'd seen to use safe_mode was all at least 2 years old. Do I really need it? If I disable PHP safe_mode are there a good set of security measures I should implement - i.e. chmod 640 /var/www/..., add this to your .htaccess, etc - to protect my server/sites? Thanks

  • TCP video streaming: TCP throughput(rate) and RTT

    - by misteryes
    we know that a rough estimation of TCP rate is: WINDOW/RTT, where WINDOW is the min(CWIN, RWIN), CWIN is the congestion window size of the sender, while RWIN is the receiving window. nowadays, the encoding rate of videos may be 1000KB/s(8000kbit/s), if RTT is 500ms, it needs the window size to be 2000KB. But we know that usually the receiving window size is below 64KB, there is a big gap. so if RTT is too large, TCP streaming is not possible? Is my understanding right? thanks!

  • Move samba and ldap config to new machine

    - by Mateusz W
    I'm not advanced administrator so this may be n00b question but I'll be grateful for help. I have following problem: I have to move my server (ubuntu server) from old machine to new. I have samba & ldap on old server, so I've copied the configuration files from the old machine to new machine, made smbldap-populate, and when I use smbldap-userlist on the new machine it lists all users from the old machine. But when I try to log in as any of these users, or show its id (id username) I get no such user error. What more I have to do to use these accounts on the new machnie?

  • Large enterprise application - clients wish to use duplicate e-mails addresses?

    - by Alex Key
    I'd like to know people's opinions, reactions to clients and technical work arounds (if applicable), to the issue of an enterprise application where a client wishes to use duplicate e-mail addresses? To clarify, when I say duplicate e-mail addresses I mean within the same client system, having multiple users that have the same e-mail address. So not just using generic e-mail addresses but using the e-mail address of another user. e.g. Bob Jenkins: [email protected] James Jeffery: [email protected] Context To give this some further context, in the e-learning sector it is common that although all staff in an organisation must complete e-learning - they may not have their own e-mail address so they choose to use their managers e-mail address. Albeit against good practice in public sites... it's a requirement we've over and over again where an organisation is split between office based staff and perhaps e.g. staff in a warehouse. Where problem lies Mr Steak, good point, the problem lies in password resets and perhaps in situations where semi-personal information could be sent (not confidential enough to worry about the insecurities of email). Perhaps reminders for specific system actions, which would be confusing for the unintended party to see (if perhaps misreading the e-mail's intended recipient) Possible solutions System knowing the difference between a "for the attention of" and direct to the person e-mails, including this in the body text. Using alternative communication such as SMS Simply not having e-mails sent to people who are not the intended recipient. Providing an e-mail service ourselfs (not really viable for a corporate IT dept) Thoughts?

  • Can I disable certificate error/warning in Firefox/Chrome/Internet Explorer?

    - by Poni
    Exactly as the title says; I don't mind which browser, I just want to type "https://........" and see the page normally without any certificate error, knowing that I might risk myself by allowing an invalid certificate! It seems like every browser producer thinks he knows better than me, the Super User !! =) Now, does anyone know how to remove warning/error related to this? In any of these browsers (Firefox/Chrome/Internet Explorer/[you-may-suggest])? Oh, and don't advise me a workaround like adding to exceptions. Please don't mention that. I'd highly appriciate a concise & precise answer! Edit: The answer I seek concerns ONLY the browser. No third-party objects to be used.

  • Handling FreeBSD package upgrades using pkg_add

    - by larsks
    I'm trying to use FreeBSD's pkg_add command to install and upgrade binary packages in a build-once-install-on-multiple-machines sort of scenario. It works well when installing a new package, but upgrades are baffling me. For example, if I want to upgrade a package that is depended on by another package, I can't just install it: # pkg_add /path/to/somepackage-2.0.tbz pkg_add: package 'somepackage' or its older version already installed At this point, I can delete the older version of the package if I pass -f to the pkg_delete command: # pkg_delete -f somepackage-1.0 pkg_delete: package 'somepackage-1.0' is required by these other packages and may not be deinstalled (but I'll delete it anyway): anotherpackage-1.0 But...and this is the killer...now the dependency information is gone! I can install the upgrade: # pkg_add /path/to/somepackage-2.0.tbz And now attempts to delete it will succeed without any errors: # pkg_delete somepackage-2.0 How do I handle this gracefully (whereby "gracefully" means "in a fashion that preserves dependency information without requiring me to rebuild/reinstall and entire dependency chain"). Thanks!

  • Earmarks of a Professional PHP Programmer

    - by Scotty C.
    I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the earmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

  • PHP + IIS Application Pool Identity Windows\Temp permissions

    - by Matt Boothman
    I am currently running PHP (5.3) on IIS 7.5 on a Win2k8 R2 Web Edition Server and would like to know what, if any, problems or security vulnerabilities I may introduct into a system by assigning Read, Write, Modify & Execute permissions to either IUSR account or the IIS_USERS group for %SystemRoot%\Temp? Should I be altering permissions to that folder at all (as Windows reminds me I probably shouldn't when i attempt to change them)? Should I create a temp folder somewhere else and set permissions accordingly? The problem is when i set Anonymous Authentication (I'm guessing is a more secure option???) to use the App Pool identity, when starting sessions PHP gets stuck in a loop because it's unable to create session files in the %SystemRoot%\Temp folder due to lack of permission on the application pool user or IIS_USERS group. Another problem being ImageMagick (PHP Extension) is being denied access to %SystemRoot%\Temp to write temporary files so is throwing exceptions. I have tried searching Google however have not found anything that touches upon this subject specifically. Any help greatly appreciated.

  • OBIEE 11.1.1.6.5 Bundle Patch released Oct 2012

    - by user554629
    October  2012 OBIEE 11.1.1.6.5 Bundle Patch released Bundle patches are collection of controlled, well tested critical bug fixes for a specific product  which may include security contents and occasionally minor enhancements. These are cumulative in nature meaning the latest bundle patch in a particular series would include the contents of the previous bundle patches released.  A suite bundle patch is an aggregation of multiple product  bundle patches that are part of a product suite. For OBIEE on 11.1.1.6.0, we plan to run a monthly bundle patch cadence. 11.1.1.6.5 bundle patch- available for download from  My Oracle Support . - is cumulative, so it includes everything from previous updates- available for supported platforms ( Windows, Linux, Solaris, AIX, HPUX-IA ) Navigate to https://support.oracle.com and login- Knowledge Base tab  Select a product line [ Business Intelligence ]  Select a Task [ Patching and Maintenance ]  Click Search- Oct 23, 2012, OBIEE 11g: Required and Recommended Patches and Patch Sets, ID 1488475.1- 11.1.1.6.5 Published 19th October 2012 Note: The 11.1.1.6 versions on top of 11.1.1.6.0 are not upgrades, they are opatch fixes.  This is not an upgrade process like from OBIEE 10g to 11g, or from OBIEE 11.1.1.5 to 11.1.1.6.  It is much safer than applying any one-off fixes, which are not regression tested.  You will be more successful using 11.1.1.6.5.

  • Intel 5100 AGN disconnects and then disables my Verizon FiOS Actiontec router

    - by Anthony
    I am a new user (my first trial) of Ubuntu and booted up my Windows Vista laptop up with the Ubuntu CD. I was able to connect wirelessly to my router and stay connected for about a minute. After that it would disconnect and my router would be disabled: none of my other wireless devices would see the signal any longer, as if it disappeared. I would have to cycle the router's power toggle off/on to get it to come back on and put out a signal again. This happened repeatedly. I experienced no other problems trying the software (i.e., accessed my files w/o issue). I did not attempt to connect with an Ethernet cable. Here are the specs on my system: laptop is HP Pavilion dv5 Notebook PC system type is 64-bit operating system CPU is Intel Core 2 Duo P8600 2.4GHz ram is 4 GB network card is Intel WiFi Link 5100 AGN I read elsewhere in this forum that 64-bit systems may not be compatible with Ubuntu. Can anyone help me with this? I'd really like to be able to use this op system.

  • Modern open source NIDS/HIDS and consoles?

    - by MattC
    Years back we set up an IDS solution by placing a tap in front of our exterior firewall, piping all the traffic on our DS1 through an IDS box and then sending the results off to a logging server running ACiD. This was around 2005-ish. I've been asked to revamp the solution and expand on it and looking around, I see that the last release of ACiD was from 2003 and I can't seem to find anything else that seems even remotely up-to-date. While these things may be feature complete, I worry about library conflicts, etc. Can anyone give me suggestions for a Linux/OpenBSD based solution using somewhat modern tools? Just to be clear, I know that Snort is still actively developed. I guess I'm more in the market for a modern open-source web console to consolidate the data. Of course if people have great experiences with IDS' other than Snort I'm happy to hear about it.

  • PostgreSQL, Ubuntu, NetBeans IDE (Part 1)

    - by Geertjan
    While setting up PostgreSQL from scratch, with the aim to use it in NetBeans IDE, I found the following resources helpful: http://railskey.wordpress.com/2012/05/19/postgresql-installation-in-ubuntu-12-04/ http://ohdevon.wordpress.com/2011/09/17/postgresql-to-netbeans-1/ http://ohdevon.wordpress.com/2011/09/19/postgresql-to-netbeans-2/ For quite a while I had problems relating to  "/var/run/postgresql/.s.PGSQL.5432", which had something to do with "postmaster.pid", which I somehow solved via a link I can't find anymore, and which may not have been a problem to begin with. A key moment was this one, which was useful for setting the password of a new user I'd created: http://stackoverflow.com/questions/7695962/postgresql-password-authentication-failed-for-user-postgres This was useful for setting up a table in my database, which I did by pasting in the below into NetBeans after I made the connection there: http://use-the-index-luke.com/sql/example-schema/postgresql/where-clause Now I have a database set up with all permissions everywhere (which turned out to be the hard part) correct: The next step will be to create a NetBeans Platform application based on this database. I'm assuming it shouldn't be any different to what's described in the NetBeans Platform CRUD Tutorial.

  • Does your programming knowledge decrease if you don't practice?

    - by Codereview
    I'm a beginner programmer, I study languages such as C/C++/Python and Java (Mainly focused on C++). I'm What you'd call "Young and inexperienced" and I admit that because I can't claim otherwise. As a student I have many other problems besides programming.I practice programming as often as I can, and especially because my teacher gives me a lot more exercises than the rest of the class (It's a very low level), so oftentimes I spend weeks doing something else such as school projects or sports, or travelling, anything besides programming. Don't get me wrong though, I love programming, I love to build functional code, to watch as a program comes alive at the push of a button and to learn as much as I can - I simply don't have much time for it. Straight to the question, now: does your programming knowledge decrease as time passes and you don't practice? You may ask "How much time do you mean?". I don't mean a specific amount of time, but for reference you could take a month-two or even a year as an example. By knowledge I mean anything: From syntax to language functionality.

  • The Bing Sting - an alternative opinion

    - by Charles Young
    I know I'm a bit of an MS fanboy at times, but please, am I missing something here? Microsoft, with permission of users, exploits clickstream data gathered by observing user behaviour. One use for this data is to improve Bing queries. Google equips twenty of its engineers with laptops and installs the widgets required to provide Microsoft with clickstream data. It then gets their engineers to repeatedly (I assume) type in 'synthetic' queries which bring back 'doctored' hits. It asks its engineers to then click these results (think about this!). So, the behaviour of the engineers is observed and the resulting clickstream data goes off to Microsoft. It is processed and 'improves' Bing results accordingly.   What exactly did Microsoft do wrong here?   Google's so-called 'Bing sting' is clearly a very effective attack from a propaganda perspective, but is poor practice from a company that claims to do no evil. Generating and sending clickstream data deliberately so that you can then subsequently claim that your competitor 'copied' that data from you is neither fair nor reasonable, and suggests to me a degree of desperation in the face of real competition.   Monopolies are undesirable, whether they are Microsoft monopolies or Google monopolies.    Personally, I'm glad Microsoft has technology in place to observe user behaviour (with permission, of course) and improve their search results using such data. I can only assume Google doesn't implement similar capabilities. Sounds to me as if, at least in this respect, Microsoft may offer the better technology.

  • Windows Embedded Compact 7

    - by Valter Minute
    This will be the official name of the new release of Windows CE. Windows Embedded Compact 7 is available as a public CTP and it already supports a wide range of CPUs and both the device emulator and VirtualPC emulated environments. So I’ll have to learn a new (and longer) name for my favorite OS… but I (and all my two readers!) will be able to test it as soon as the download from connect web site completes (I'm sorry for my readers, but you'll have to download it by yourselves). Here’s a link for the download (it's free but you’ll have to register on connect with a valid LiveId): https://connect.microsoft.com/windowsembeddedce Remember that this is still a beta (or “Community Technology Preview” if you speak marketing language) and so it’s better to not install it on your main development PC (or, at least, backup everything before installation) and that the features and performances you’ll get from this beta may not be the same ones of the final release of the OS. You can discover the new features of Windows Embedded Compact on the new “official” webpage on microsoft website: http://www.microsoft.com/windowsembedded/en-us/products/windowsce/compact7.mspx or on Olivier’s blog: http://blogs.msdn.com/b/obloch/archive/2010/06/01/windows-embedded-compact-7-announced-and-public-ctp-available.aspx I hope to be able to post some interesting content about Windows Embedded Compact 7 soon (and maybe be able to shorten it’s name in CE7 in my blog posts, when I'll ensure that both my readers are not worketing for Microsoft's marketing department …).

  • Video on Hyperion Tax Provision

    - by Lia Nowodworska - Oracle
    ( in via Jan) EPM Information Development has asked us to remind you about the new video available for Hyperion Tax Provision. You can view it on the OracleEPMWebcasts YouTube channel here: http://bit.ly/1jxLlCy An information rich 4:40 minutes of your time.  So please take a look. The video gives a brief overview of the main features of  Hyperion Tax Provision. You will learn ... That Tax Provision and reporting System builds on the Hyperion Financial Close Reporting Platform That much of the Tax Provision flow process is similar to the Financial Close Process and that the modules have been aligned to work together very closely. That HTP enables you to integrate Book- and Tax Reporting on a common platform. That It uses the technology of HFM, ties in with SmartView and can be used with Hyperion Financial Reporting. That the native integration between the Financial System and the Tax System creates transparency for the Tax Departments and removes bottlenecks in the tax process. More technical information can be found here: Oracle Hyperion Tax Provision Data Sheet Oracle Hyperion Tax Provision White Paper Oracle Hyperion Tax Provision Documentation If you have another 45 minutes to spare and want to get into greater detail, then you can check out the recording of an Advisor Webcast that we did earlier last year: You can find this via KM Doc Oracle Business Analytics Advisor Webcast Schedule and Archive Recordings (Doc ID 1456233.1) -> Select the Tab "Archived 2013" and it is the third from the top: "Oracle Hyperion Tax Provision - Features and Overview with Demo" If you have questions towards that Advisor Webcast, you may participate in the Community Discussion about it.

  • Do you keep your ideas secret? and why?

    - by MainMa
    I believe any programmer has several ideas that she/he considers as innovative or at least valuable. It may be an idea of a new product which will make this world better or a new development approach, etc. But a great idea must be implemented and promoted/advertised. This requires a lot of work (proofs of concept, prototypes, technology previews, etc.) and a lot of money (appropriate advertisement, marketing, etc.). So months later, the idea stays in our heads, but nothing else is done, because it's difficult, long and expensive, sometimes even impossible for a single developer. On the other hand, it would be painful to share our ideas, and see a medium-size company which has enough resources making something useful from it and having success and money. So what do you do with your ideas you can hardly implement or patent? Do you talk freely about them in discussion boards and with other developers? Do you keep them like a precious thing without never talking about them to anybody? If you keep your ideas, why are you doing so? Is it just because you hope that one day, you will be able to implement them and have a huge success, while you know very well by experience that it's an utopia?

  • How to Generate a Create Table DDL Script Along With Its Related Tables

    - by Compudicted
    Have you ever wondered when creating table diagrams in SQL Server Management Studio (SSMS) how slickly you can add related tables to it by just right-clicking on the interesting table name? Have you also ever needed to script those related tables including the master one? And you discovered you have dozens of related tables? Or may be no SSMS at your disposal? That was me one day. Well, creativity to the rescue! I Binged and Googled around until I found more or less what I wanted, but it was all involving T-SQL, yeah, a long and convoluted CROSS APPLYs, then I saw a PowerShell solution that I quickly adopted to my needs (I am not referencing any particular author because it was a mashup): 1: ########################################################################################################### 2: # Created by: Arthur Zubarev on Oct 14, 2012 # 3: # Synopsys: Generate file containing the root table CREATE (DDL) script along with all its related tables # 4: ########################################################################################################### 5:   6: [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null 7:   8: $RootTableName = "TableName" # The table name, no schema name needed 9:   10: $srv = new-Object Microsoft.SqlServer.Management.Smo.Server("TargetSQLServerName") 11: $conContext = $srv.ConnectionContext 12: $conContext.LoginSecure = $True 13: # In case the integrated security is not used uncomment below 14: #$conContext.Login = "sa" 15: #$conContext.Password = "sapassword" 16: $db = New-Object Microsoft.SqlServer.Management.Smo.Database 17: $db = $srv.Databases.Item("TargetDatabase") 18:   19: $scrp = New-Object Microsoft.SqlServer.Management.Smo.Scripter($srv) 20: $scrp.Options.NoFileGroup = $True 21: $scrp.Options.AppendToFile = $False 22: $scrp.Options.ClusteredIndexes = $False 23: $scrp.Options.DriAll = $False 24: $scrp.Options.ScriptDrops = $False 25: $scrp.Options.IncludeHeaders = $True 26: $scrp.Options.ToFileOnly = $True 27: $scrp.Options.Indexes = $False 28: $scrp.Options.WithDependencies = $True 29: $scrp.Options.FileName = 'C:\TEMP\TargetFileName.SQL' 30:   31: $smoObjects = New-Object Microsoft.SqlServer.Management.Smo.UrnCollection 32: Foreach ($tb in $db.Tables) 33: { 34: Write-Host -foregroundcolor yellow "Table name being processed" $tb.Name 35: 36: If ($tb.IsSystemObject -eq $FALSE -and $tb.Name -eq $RootTableName) # feel free to customize the selection condition 37: { 38: Write-Host -foregroundcolor magenta $tb.Name "table and its related tables added to be scripted." 39: $smoObjects.Add($tb.Urn) 40: } 41: } 42:   43: # The actual act of scripting 44: $sc = $scrp.Script($smoObjects) 45:   46: Write-host -foregroundcolor green $RootTableName "and its related tables have been scripted to the target file." Enjoy!

  • Any good reason open files in text mode?

    - by Tinctorius
    (Almost-)POSIX-compliant operating systems and Windows are known to distinguish between 'binary mode' and 'text mode' file I/O. While the former mode doesn't transform any data between the actual file or stream and the application, the latter 'translates' the contents to some standard format in a platform-specific manner: line endings are transparently translated to '\n' in C, and some platforms (CP/M, DOS and Windows) cut off a file when a byte with value 0x1A is found. These transformations seem a little useless to me. People share files between computers with different operating systems. Text mode would cause some data to be handled differently across some platforms, so when this matters, one would probably use binary mode instead. As an example: while Windows uses the sequence CR LF to end a line in text mode, UNIX text mode will not treat CR as part of the line ending sequence. Applications would have to filter that noise themselves. Older Mac versions only use CR in text mode as line endings, so neither UNIX nor Windows would understand its files. If this matters, a portable application would probably implement the parsing by itself instead of using text mode. Implementing newline interpretation in the parser might also remove some overhead of using text mode, as buffers would need to be rewritten (and possibly resized) before returning to the application, while this may be less efficient than when it would happen in the application instead. So, my question is: is there any good reason to still rely on the host OS to translate line endings and file truncation?
