  • Meta package / quick reference for string manipulation commands?

    - by Dylan McCall
    The latest version of the Scribes text editor lets us select some text, hit Alt+X, and then run an arbitrary command. For example, I can run the sort command and the selected text is replaced appropriately. This is quite useful but I am also not very well-versed in awk and the like. Is there something I can grab that will provide more of these commands like sort? Maybe a package with a whole bunch of handy, task-specific string manipulation commands?

  • Windows CE: Changing Static IP Address

    - by Bruce Eitman
    A customer contacted me recently and asked me how to change a static IP address at runtime.  Of course this is not something that I know how to do, but with a little bit of research I figure out how to do it. It turns out that the challenge is to request that the adapter update itself with the new IP Address.  Otherwise, the change in IP address is a matter of changing the address in the registry for the adapter.   The registry entry is something like: [HKEY_LOCAL_MACHINE\Comm\LAN90001\Parms\TcpIp]    "EnableDHCP"=dword:0    "IpAddress"="192.168.0.100"     "DefaultGateway"="192.168.0.1"    "Subnetmask"="255.255.255.0" Where LAN90001 would be replace with your adapter name.  I have written quite a few articles about how to modify the registry, including a registry editor that you could use. Requesting that the adapter update itself is a matter of getting a handle to the NDIS driver, and then asking it to refresh the adapter.  The code is: #include <windows.h> #include "winioctl.h" #include "ntddndis.h"   void RebindAdapter( TCHAR *adaptername ) {       HANDLE hNdis;       BOOL fResult = FALSE;       int count;         // Make this function easier to use - hide the need to have two null characters.       int length = wcslen(adaptername);       int AdapterSize = (length + 2) * sizeof( TCHAR );       TCHAR *Adapter = malloc(AdapterSize);       wcscpy( Adapter, adaptername );       Adapter[ length ] = '\0';       Adapter[ length +1 ] = '\0';           hNdis = CreateFile(DD_NDIS_DEVICE_NAME,                   GENERIC_READ | GENERIC_WRITE,                   FILE_SHARE_READ | FILE_SHARE_WRITE,                   NULL,                   OPEN_ALWAYS,                   0,                   NULL);         if (INVALID_HANDLE_VALUE != hNdis)       {             fResult = DeviceIoControl(hNdis,                         IOCTL_NDIS_REBIND_ADAPTER,                         Adapter,                         AdapterSize,                         NULL,                         0,                         &count,                         NULL);             if( !fResult )             {                   RETAILMSG( 1, (TEXT("DeviceIoControl failed %d\n"), GetLastError() ));             }             CloseHandle(hNdis);       }       else       {             RETAILMSG( 1, (TEXT("Failed to open NDIS Handle\n")));       }   }       int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR    lpCmdLine, int       nCmdShow) {     RebindAdapter( TEXT("LAN90001") );     return 0; }   If you don’t want to write any code, but instead plan to use a registry editor to change the IP Address, then there is a command line utility to do the same thing.  NDISConfig.exe can be used: Ndisconfig adapter rebind LAN90001    Copyright © 2012 – Bruce Eitman All Rights Reserved

  • Visio drawing in SharePoint 2007

    - by MartinIsti
    Yesterday I decided to improve a SharePoint site a bit by replacing the very basic navigation web part ( content editor web part with a 5x4 table that contains only text with hyperlinks and very far from being pretty) with something fancier. I decided to use Visio for that. I created a quite simple chart: Simple I admit, but much better than this one: Do you agree? ;o) I think I will make the visio drawing a bit fancier but the main point of this blog is how to publish it into a SharePoint site?...(read more)

  • Can LittleBigPlanet2's engine be used for other ?

    - by Bill
    LittleBigPlanet2 just came out. I've worked with the original LBP level editor a bit and really enjoyed it. I've read that LBP2's featureset in the game is much richer; is it possible to use these advanced features to create different sorts of game other than just a regular platformer? I imagine that something along the lines of a Breakout clone would definitely be manageable, but I'm interested in hearing more about the capabilities of the platform.

  • Create Image Maps with GIMP

    - by SGWellens
    Having a clickable image in a web page is not a big deal. Having an image in a web page with clickable hotspots is a big deal. The powerful GIMP editor has a tool to make creating clickable hotspots much easier. GIMP stands for GNU Image Manipulation Program. Its home page and download links are here: http://www.gimp.org/ (it is completely free). Beware: GIMP is an extraordinarily advanced and powerful image editor. If you wish to use it for general image editing tasks, you have a steep learning curve to climb. FYI: I used it to create the shadows you see on the images below. Fortunately, the tool to make Image Maps is separate from the main program. To start, open an image with GIMP or, drag and drop an image onto the GIMP main window. I'm using the image of a bar graph. Next, we have to find the Image Map tool and launch it (Filters->Web->Image Map…): Why is the Image Map tool under Filters and not Tools? I don't know. It's mystery—much like the Loch Ness Monster, the Bermuda Triangle, or why my socks keep disappearing when I do laundry. I swear I've got twenty single unmatched socks. But I digress… Here is what the Image Map tool looks like: If we click the blue 'I' button, we can add information to the Image Map: Now we'll use the rectangle tool to create some clickable hotspots. Select the Blue Rectangle tool, drag a rectangle, click when done and you'll get something like this: You can also make circle/oval and polygon areas. You can edit all the parameters of an image map area after drawing it. Rectangle settings (for fine tweaking): JavaScript functions (it's up to you to write them): Here is a setup with two rectangles and one polygon area: When you hit save a map file is generated that looks something like this: Paste the contents into a web page and you are almost there. I made some tweaks before it became usable: Replaced &apos; with apostrophes in the javascript functions. Changed the image path so it would find the image in my images directory Tweaked the href urls. Added Title="Some Text" to get tool tips. Cleaned out the comments. Result: The final markup (with JavaScript function): function ImageMapMouseHover(Msg) { $("#Label1").html(Msg); } It may seem like a lot of bother but, the tool does the heavy lifting: i.e. the coordinates. Getting the regions positioned and sized is easy using a visual tool…much better than doing it by hand. This, of course, isn't a full treatise on the tool but it should give you enough information to decide if it's helpful. I hope someone finds this useful Steve Wellens

  • Always keep files updated in Eclipse

    - by AK01
    I keep lots of files/editors open in Eclipse. I also love using git stash and other git commands that essentially change the contents of my open files. Is there an Eclipse feature or plugin that will always keep the contents of my open files up to date and live? Currently if I put focus in an out of sync editor, I get an awkwardly worded dialog that I have to parse carefully every time. I wish it would just keep me synced like Textmate does.

  • Sprites are sometimes blurry in Flash

    - by Tim Cooper
    I am playing around with drawing an SVG sprite (imported in through [Embed]). Depending on the coordinates of the image, sometimes it appears more crisp than others. The following image shows how at different locations is it rendered differently: (Image link - You may have to download and zoom in with an image editor to see it) You'll notice that the middle sprite is more blurry than the ones on the sides. Does anyone know why this is? Any help would be appreciated.

  • A few questions about integrating AudioKinetic Wwise and Unity

    - by SaldaVonSchwartz
    I'm new to Wwise and to using it with Unity, and though I have gotten the integration to work, I'm still dealing with some loose ends and have a few questions: (I'm on Unity 4.3 as of now but I think it shouldn't make any difference) The base path: The Wwise documentation implies you set this in the AkGlobalSoundEngineInitializer basePath public ivar, which is exposed to the editor. However, I found that this variable is not really used. Instead, the path is hardcoded to /Audio/GeneratedSoundBanks in AkBankPath. I had to modify both scripts to actually look in the path that I set in the editor property. What's the deal with this? Just sloppyness or am I missing something? Also about paths: since I'm on Mac, I'm using Unity natively under OS X and in tadem, the Wwise authoring tool via VMWare and I share the OS X Unity project folder so I can generate the soundbanks into the assets folder. However, the authoring tool (downloaded the latest one for Windows) doesn't automatically generate any "platform-specific" subfolders for my wwise files. That is, again, the Unity integration scripts assume the path to be /Audio/GeneratedSoundBanks/<my-platform>/ which in my case would be Mac (I set the authoring tool to generate for Mac). The documentation says wwise will automatically generate the platform-specific folders but it just dumps all the stuff in GeneratedSoundBanks. Am I missing some setting? cause right now I just manually create the /Mac folder. The C# methods AkSoundEngine.PostEvent and AkSoundEngine.LoadBank for instance, have a few overloads, including ones where I can refer to the soundbanks or events by their ID. However, if I try to use these, for instance: AkSoundEngine.LoadBank(, AkSoundEngine.AK_DEFAULT_POOL_ID) where the int I got from the .h header, I get Ak_Fail. If I use the overloads that reference the objects by string name then it works. What gives? Converting the ID header to C#: The integration comes with a C# script that seems to fork a process to call Python in turn to covert the C++ header into a C# script. This always fails unless I manually execute the Python script myself from outside Unity. Might be a permissions thing, but has anyone experienced this? The Profiler: I set up the Unity player to run in the background and am using the "Profile" version of the plugin. However, when I start the Unity OS X standalone app, the profiler in VMWare does not see it. This I'm thinking might just be that I'm trying to see a running instance of the sound engine inside an OS X binary from a Windows virtual machine. But I'm just wondering if anyone has gotten the Windows profiler to see an OS X Unity binary. Different versions of the integration plugin: It's not clear to me from the documentation whether I have to manually (or write a script to do it) remove the "Profile" version and install the "Release" version when I'm going to do a Release build or if I should install both version in Unity and it'll select the right one. Thanks!

  • SQL SERVER – Using expressor Composite Types to Enforce Business Rules

    - by pinaldave
    One of the features that distinguish the expressor Data Integration Platform from other products in the data integration space is its concept of composite types, which provide an effective and easily reusable way to clearly define the structure and characteristics of data within your application.  An important feature of the composite type approach is that it allows you to easily adjust the content of a record to its ultimate purpose.  For example, a record used to update a row in a database table is easily defined to include only the minimum set of columns, that is, a value for the key column and values for only those columns that need to be updated. Much like a class in higher level programming languages, you can also use the composite type as a way to enforce business rules onto your data by encapsulating a datum’s name, data type, and constraints (for example, maximum, minimum, or acceptable values) as a single entity, which ensures that your data can not assume an invalid value.  To what extent you use this functionality is a decision you make when designing your application; the expressor design paradigm does not force this approach on you. Let’s take a look at how these features are used.  Suppose you want to create a group of applications that maintain the employee table in your human resources database. Your table might have a structure similar to the HumanResources.Employee table in the AdventureWorks database.  This table includes two columns, EmployeID and rowguid, that are maintained by the relational database management system; you cannot provide values for these columns when inserting new rows into the table. Additionally, there are columns such as VacationHours and SickLeaveHours that you might choose to update for all employees on a monthly basis, which justifies creation of a dedicated application. By creating distinct composite types for the read, insert and update operations against this table, you can more easily manage this table’s content. When developing this application within expressor Studio, your first task is to create a schema artifact for the database table.  This process is completely driven by a wizard, only requiring that you select the desired database schema and table.  The resulting schema artifact defines the mapping of result set records to a record within the expressor data integration application.  The structure of the record within the expressor application is a composite type that is given the default name CompositeType1.  As you can see in the following figure, all columns from the table are included in the result set and mapped to an identically named attribute in the default composite type. If you are developing an application that needs to read this table, perhaps to prepare a year-end report of employees by department, you would probably not be interested in the data in the rowguid and ModifiedDate columns.  A typical approach would be to drop this unwanted data in a downstream operator.  But using an alternative composite type provides a better approach in which the unwanted data never enters your application. While working in expressor  Studio’s schema editor, simply create a second composite type within the same schema artifact, which you could name ReadTable, and remove the attributes corresponding to the unwanted columns. The value of an alternative composite type is even more apparent when you want to insert into or update the table.  In the composite type used to insert rows, remove the attributes corresponding to the EmployeeID primary key and rowguid uniqueidentifier columns since these values are provided by the relational database management system. And to update just the VacationHours and SickLeaveHours columns, use a composite type that includes only the attributes corresponding to the EmployeeID, VacationHours, SickLeaveHours and ModifiedDate columns. By specifying this schema artifact and composite type in a Write Table operator, your upstream application need only deal with the four required attributes and there is no risk of unintentionally overwriting a value in a column that does not need to be updated. Now, what about the option to use the composite type to enforce business rules?  If you review the composition of the default composite type CompositeType1, you will note that the constraints defined for many of the attributes mirror the table column specifications.  For example, the maximum number of characters in the NationaIDNumber, LoginID and Title attributes is equivalent to the maximum width of the target column, and the size of the MaritalStatus and Gender attributes is limited to a single character as required by the table column definition.  If your application code leads to a violation of these constraints, an error will be raised.  The expressor design paradigm then allows you to handle the error in a way suitable for your application.  For example, a string value could be truncated or a numeric value could be rounded. Moreover, you have the option of specifying additional constraints that support business rules unrelated to the table definition. Let’s assume that the only acceptable values for marital status are S, M, and D.  Within the schema editor, double-click on the MaritalStatus attribute to open the Edit Attribute window.  Then click the Allowed Values checkbox and enter the acceptable values into the Constraint Value text box. The schema editor is updated accordingly. There is one more option that the expressor semantic type paradigm supports.  Since the MaritalStatus attribute now clearly specifies how this type of information should be represented (a single character limited to S, M or D), you can convert this attribute definition into a shared type, which will allow you to quickly incorporate this definition into another composite type or into the description of an output record from a transform operator. Again, double-click on the MaritalStatus attribute and in the Edit Attribute window, click Convert, which opens the Share Local Semantic Type window that you use to name this shared type.  There’s no requirement that you give the shared type the same name as the attribute from which it was derived.  You should supply a name that makes it obvious what the shared type represents. In this posting, I’ve overviewed the expressor semantic type paradigm and shown how it can be used to make your application development process more productive.  The beauty of this feature is that you choose when and to what extent you utilize the functionality, but I’m certain that if you opt to follow this approach your efforts will become more efficient and your work will progress more quickly.  As always, I encourage you to download and evaluate expressor Studio for your current and future data integration needs.

  • How to Assign a Default Signature in Outlook 2013

    - by Lori Kaufman
    If you sign most of your emails the same way, you can easily specify a default signature to automatically insert into new email messages and replies and forwards. This can be done directly in the Signature editor in Outlook 2013. We recently showed you how to create a new signature. You can also create multiple signatures for each email account and define a different default signature for each account. When you change your sending account when composing a new email message, the signature would change automatically as well. NOTE: To have a signature added automatically to new email messages and replies and forwards, you must have a default signature assigned in each email account. If you don’t want a signature in every account, you can create a signature with just a space, a full stop, dashes, or other generic characters. To assign a default signature, open Outlook and 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. On the Mail screen, click Signatures in the Compose messages section. To change the default signature for an email account, select the account from the E-mail account drop-down list on the top, right side of the dialog box under Choose default signature. Then, select the signature you want to use by default for New messages and for Replies/forwards from the other two drop-down lists. Click OK to accept your changes and close the dialog box. Click OK on the Outlook Options dialog box to close it. You can also access the Signatures and Stationery dialog box from the Message window for new emails and drafts. Click New Email on the Home tab or double-click an email in the Drafts folder to access the Message window. Click Signature in the Include section of the New Mail Message window and select Signatures from the drop-down menu. In the next few days, we will be covering how to use the features of the signature editor next, and then how to insert and change signatures manually, backup and restore your signatures, and modify a signature for use in plain text emails.

  • Merge Join component sorted outputs [SSIS]

    - by jamiet
    One question that I have been asked a few times of late in regard to performance tuning SSIS data flows is this: Why isn’t the Merge Join output sorted (i.e.IsSorted=True)? This is a fair question. After all both of the Merge Join inputs are sorted, hence why wouldn’t the output be sorted as well? Well here’s a little secret, the Merge Join output IS sorted! There’s a caveat though – it is only under certain circumstances and SSIS itself doesn’t do a good job of informing you of it. Let’s take a look at an example. Here we have a dataflow that consumes data from the [AdventureWorks2008].[Sales].[SalesOrderHeader] & [AdventureWorks2008].[Sales].[SalesOrderDetail] tables then joins them using a Merge Join component: Let’s take a look inside the editor of the Merge Join: We are joining on the [SalesOrderId] field (which is what the two inputs just happen to be sorted upon). We are also putting [SalesOrderHeader].[SalesOrderId] into the output. Believe it or not the output from this Merge Join component is sorted (i.e. has IsSorted=True) but unfortunately the Merge Join component does not have an Advanced Editor hence it is hidden away from us. There are a couple of ways to prove to you that is the case; I could open up the package XML inside the .dtsx file and show you the metadata but there is an easier way than that – I can attach a Sort component to the output. Take a look: Notice that the Sort component is attempting to sort on the [SalesOrderId] column. This gives us the following warning: Validation warning. DFT Get raw data: {992B7C9A-35AD-47B9-A0B0-637F7DDF93EB}: The data is already sorted as specified so the transform can be removed. The warning proves that the output from the Merge Join is sorted! It must be noted that the Merge Join output will only have IsSorted=True if at least one of the join columns is included in the output. So there you go, the Merge Join component can indeed produce a sorted output and that’s very useful in order to avoid unnecessary expensive Sort operations downstream. Hope this is useful to someone out there! @Jamiet  P.S. Thank you to Bob Bojanic on the SSIS product team who pointed this out to me!

  • vi issue in SSH TTYs to Ubuntu 14.04.1 LTS

    After upgrading my server to Ubuntu 14.04.1 LTS, I can no longer use the vi editor to edit anything in an SSH terminal (I access the server by launching ssh sessions from Cygwin running on Windows). The empty portions of the vi window fill with garbage. The workaround is to launch an xterm from the server back to my Cygwin/X display. Using vi from within the xterm works fine. Setting my TERM to vt100/vt220/xterm does not help.

  • Does Sublime's "minimap" improve productivity?

    - by Casey Patton
    I'm a pretty big fan of Sublime. One of my favorite features is the ability to scroll through your file by using the compressed image of your text on the upper right hand corner (minimap). My gut feeling is this does positive things for productivity: Does having this minimap to scroll through actually improve productivity? P.S. - Side question: Did Sublime invent this idea, or did they take it from another text editor?
