• Setting Up Your SQL Server Agent Correctly

  It is important to set up SQL Server Agent Security on the principles of 'executing with minimum privileges’, and ensure that errors are properly logged and alerts are set up for a comprehensive range of errors. SQL Server Agent allows fine-grained control of every job step that should allow tasks to be run entirely safely even if they occasionally need special privileges. Can 41,000 DBAs really be wrong?

• Is there any way around the field-of-use restrictions in Java?

  - by Muton

  Current field-of-use restrictions defined in "Oracle Binary Code License Agreement for the Java SE Platform Products" prohibit its use in embedded systems. "General Purpose Desktop Computers and Servers" means computers, including desktop and laptop computers, or servers, used for general computing functions under end user control (such as but not specifically limited to email, general purpose Internet browsing, and office suite productivity tools). The use of Software in systems and solutions that provide dedicated functionality (other than as mentioned above) or designed for use in embedded or function-specific software applications... are excluded from this definition and not licensed under this Agreement. Do these restrictions also apply to OpenJDK and other possible implementations? Is the only way to use Java in such an environment to acquire a separate license from Oracle?

• Most underestimated programming tool [closed]

  - by Anto

  We have many great tools which helps a lot when programming, such as good programmers text editors, IDEs, debuggers, version control systems etc. Some of the tools are more or less "must have" tools for getting the job done (e.g. compilers). There are still always tools which do help a lot, but still don't get so much attention, for various reasons, for instance, when they were released, they were ahead of their time and now are more or less forgotten. What type of programming tool do you think is the most underestimated one? Motivate your answer.

• What is causing Unity to be slow on startup?

  - by To Do

  A few days ago I noticed that after I login in, the top panel and the dash took a bit more time to load and I noticed more disc activity than usual. I thought that it might have been caused by some update or by the installation of pdftk. So I removed pdftk but the "problem" persists. Is there a way to know what is using the disc (read/write operations) on startup? If it were at a later time, I would use iotop but I can only launch iotop after I get control of the desktop. I'm on Ubuntu 12.10 amd64.

• Ubuntu launch option on startup remains

  - by rQw

  I used windows installer to install Ubuntu and it was getting errors on bootup. Well that didn't work, I guess I'll try and boot from a USB to install it. However, after messing around with uninstalling (aka deleting Ubuntu folder after booting into Win7) I cannot get rid of the launch option. There is nothing in Computer Management because I never actually booted into Ubuntu to create space on my HDD for the OS. I can't just uninstall using Program and Features in Control Panel (because I already deleted the folder) Now everytime I boot up it gives me the options of booting into Windows 7 or Ubuntu, how do I disable this page/get rid of the Ubuntu launch option?

• Forbidding or controlling "Hidden IT..." Who should write and maintain ad-hoc software applications?

  - by matcauthon

  Bigger companies usually have the problem, that it is not possible to write all programs employees want (to save time and to optimize processes) due to a lack of staff and money. Then hidden programs will be created by some people having (at least some) coding experience (or by cheap students/interns...). Under some circumstances these applications will raise in importance and spread from one user to a whole department. Then there is the critical point: Who will maintain the application, add new features, ...? And this app is critical. It IS needed. But the intern has left the company. No one knows how it works. You only have a bunch of sources and some sort of documentation. Does it make sense to try and control or forbid application development done ad-hoc outside of the IT department (with the exception of minor stuff like Excel macros)?

• Non Blocking Keyboard on WinCE accessing the virtual keyboard

  - by Jan H.

  Hello Guys, I am desperately looking for a solution that enables me to read keyboard events in a non blocking way. These Keyboard events are generated by a VIRTUAL KEYBOARD that comes with the WinCE device. I have a console application running in C++, where the user is asked to navigate via 'ESC', 'U' and other characters through the menu. I first tried to use fread and stdin and realised that it is blocking call and waits for a carriage return. Then I tried to hook up to the windows message WM_KEYUP, but I never recieve this windows message. Furthermore I tried to use QtGUI together with the event QKeyEvent, but I never recieve any event. I wonder if it is in general possible to recieve non-blocking keyboard events on a WinCE device. I would be glad if you have any suggestions! Cheers, Jan

• XML parsing error: 'A string literal was expected' when inserting values into table

  - by Christian

  In Microsoft Sequel Server 2008 I am attempting to insert values into an sql table with the columns type_id of datatype int and xml_info of datatype XML. I am using the following query: INSERT INTO tbl_applied_devices ([type_id],[xml_info]) VALUES (1,'<Profile ID=99><Server><ID>BC4A18CA-AFB5-4268-BDA9-C990DAFE7783</ID> <Name>localhost</Name><Services></Services></Server></Profile>') But I keep getting this error: Msg 9413, Level 16, State 1, Line 4 XML parsing: line 1, character 13, A string literal was expected What am I doing incorrectly? Thank you for the help. EDIT: I found that the source of the error is the xml element's ID attribute, where seems to be what is causing the error. How can I correctly insert xml with an attribute ? Do I need to somehow escape one of the characters?

• How can I truncate an NSString to a set length?

  - by nevan

  I searched, but surprisingly couldn't find an answer. I have a long NSString that I want to shorten. I want the maximum length to be around 20 characters. I read somewhere that the best solution is to use substringWithRange. Is this the best way to truncate a string? NSRange stringRange = {0,20}; NSString *myString = @"This is a string, it's a very long string, it's a very long string indeed"; NSString *shortString = [myString substringWithRange:stringRange]; It seems a little delicate (crashes if the string is shorter than the maximum length). I'm also not sure if it's Unicode-safe. Is there a better way to do it? Does anyone have a nice category for this?

• Print raw data to a thermal-printer using c#

  - by blauesocke

  Hi, I'm trying to print out raw ascii data to a thermal printer. I do this by using this code example: http://support.microsoft.com/kb/322091 but my printer prints always only one character and this not until I press the form feed button. If I print something with notepad the printer will do a form feed automatically but without printing any text. The printer is connected via usb over a lpt2usb adapter and Windows 7 uses the "Generic - Generic / Text Only" driver. Anyone knows what is going wrong? How is it possible to print some words and do some form feeds? Are there some control characters I have to send? And if yes: How do I send them? Thanks!

• WPF, PreviewKeyDown event and underscore char

  - by commanderz

  Hi, I'm catching key hits with PreviewKeyDown event in my WPF component. I need to distinguish characters being typed: letters vs. numbers vs. underscore vs. anything else. Letters and numbers work fine (just convert the Key property of the KeyEventArgs object to string and work with character 0 of that string), but this won't work for underscore. It's ToString value depends on localized keyboard settings (it shows up as "OemMinus" on EN/US keyboard and "OemQuestion" on CZ/QWERTY keyboard). So how can I RELIABLY find out, if the typed char is underscore in the PreviewKeyDown event? Thanks for any help

• Fail to launch application (CreateProcess error=87), can't use shorten classpath workaround

  - by Ivo Bosticky

  When I launch our application in Eclipse on Windows I receive the following error: Exception occured executing command line. Cannot run program .. : CreateProcess error=87, The parameter is incorrect I've solved this in the past by shortening the CLASSPATH. I've now come to a point where I can no longer shorten the CLASSPATH, and would like to know if there are any other workarounds. http://support.microsoft.com/kb/830473 seems to indicate that the max command prompt line length in windows xp is 8191 characters, and the only solution is to shorten folder names, reduce depth of folder trees, using parameter files, etc.

• Regex to leave desired string remaining and others removed

  - by m7d

  In Ruby, what regex will strip out all but a desired string if present in the containing string? I know about /[^abc]/ for characters, but what about strings? Say I have the string "group=4&type_ids[]=2&type_ids[]=7&saved=1" and want to retain the pattern group=\d, if it is present in the string using only a regex? Currently, I am splitting on & and then doing a select with matching condition =~ /group=\d/ on the resulting enumerable collection. It works fine, but I'd like to know the regex to do this more directly.

• MySQL and GROUP_CONCAT() maximum length

  - by zewaren

  Hello everyone, I'm using GROUP_CONCAT() in a MySQL query to convert multiple rows into a single string. However, the maximum length of the result of this function is 1024 characters. I'm very well aware that I can change the param group_concat_max_len to increase this limit: SET SESSION group_concat_max_len = 1000000; However, on the server I'm using, I can't change any param. Not by using the preceding query and not by editing any configuration file. So my question is: Is there any other way to get the output of a multiple row query into a single string? Thank you for your answers.

• device.uuid undefined in PhoneGap on Android?

  - by Steve Nay

  I'm writing a PhoneGap application that sends requests to a central database. It needs to be able to identify the unique devices that connect to it. PhoneGap's device.uuid property would seem to do the trick. On webOS and iPhone, I get back a unique string of alphanumeric characters, which will satisfy my need. However, the Android devices I've tested (Motorola Droid and the Android SDK emulator, both running Android 2.1) return "undefined" as the device.uuid. device.platform and device.name return correct values on all three platforms, so the problem doesn't have to do with the device object itself (it's defined in the code blocks where I use it). Is this an Android limitation? A problem with PhoneGap? Is there any other way to get such a globally unique identifier if not through device.uuid? EDIT: It appears that the deviceready event is never getting fired, which needs to happen before the device.uuid property becomes available.

• Encryption Product Keys : Public and Private key encryption

  - by Aran Mulholland

  I need to generate and validate product keys and have been thinking about using a public/private key system. I generate our product keys based on a client name (which could be a variable length string) a 6 digit serial number. It would be good if the product key would be of a manageable length (16 characters or so) I need to encrypt them at the base and then distrubute the decryption/validation system. As our system is written in managed code (.NET) we dont want to distribute the encryption system, only the decryption. I need a public private key seems a good way to do this, encrypt with the one key that i keep and distribute the other key needed for decrpytion/verification. What is an appropriate mechanism to do this with the above requirements?

• Parsing ISO-8859-1 w/ NSXmlParser

  I am usin the nsxmlparser and am wondering how I can parse ISO-8859-1 correctly into an NSString. Currently, I am getting results w/ Â for two-byte characters. The XML I'm using (not created by me) starts with <?xml version="1.0" encoding="ISO-8859-1"?> Here are the basic calls I'm using (omitted the NSThread calls).

• Integer ID obfuscation techniques

  - by Chris

  Hi there, I'm looking for an easy and reversible method of obfuscating integer IDs. Ideally, I'd want the resulting obfuscation to be at most eight characters in length and non-sequential, meaning that the obfuscation of "1" should look nothing like the obfuscation for "2" and so on. This isn't meant to be secure by any means, so this isn't a huge concern. Additionally, the integers I'll be obfuscating aren't large - between one and 10,000 - but I don't want any collisions, either. Does anybody have any ideas for something that would fit this criteria? Thanks! Chris

• SQL Server -> 'SQL_Latin1_General_CP1_CI_AS' Collation -> Varchar Column -> Languages Supported

  - by Ajay Singh

  All, We are using SQL Server 2008 with Collation Setting as 'SQL_Latin1_General_CP1_CI_AS'. We are using Varchar column to store textual data. We know that we cannot store Double Byte data in Varchar column and hence cannot support languages like Japanese and Chinese without converting it to NVarchar. However, will it be safe to say that all Single Byte Characters can be stored in Varchar column without any problem? If yes then from where can I get the list of languages which needs Single Byte for storage and the list of languages which needs double byte? Any assistance in this regard is highly appreciated. Thanks in advance.

• PHP explode not filling in array spot 0

  - by Billy Winterhouse

  I have a file we will call info.txt under UNIX format that has only the following in it: #Dogs #Cats #Birds #Rabbits and am running this against it: $filename = "info.txt"; $fd = fopen ($filename, "r"); $contents = fread ($fd,filesize ($filename)); fclose ($fd); $delimiter = "#"; $insideContent = explode($delimiter, $contents); Now everything looks to be working fine except when I display the array I get the following. [0] => [1] => Dogs [2] => Cats [3] => Birds [4] => Rabbits I checked the .txt file to make sure there wasn't any space or hidden characters in front of the first # so I'm at a loss of why this is happening other than I feel like I'm missing something terribly simple. Any ideas? Thanks in advanced!

• RPG Game loop and class structure (cocos2D for iPhone)

  - by mac_55

  I'm looking to make an RPG with Cocos2D on the iPhone. I've done a fair bit of research, and I really like the model Cocos2D uses for scenes. I can instantiate a scene, set up my characters etc. and it all works really nicely... what I have problems with is structuring a game loop and separating the code from the scenes. For example, where do I put my code that will maintain the state of the game across multiple scenes? and do I put the code for events that get fired in a scene in that scene's class? or do I have some other class that separates the init code from the logic? Also, I've read a lot of tutorials that mention changing scenes, but I've read none that talk about updating a scene - taking input from the user and updating the display based on that. Does that happen in the scene object, or in a separate display engine type class. Thanks in advance!
