    - by Kimi
    I want to grep an environment variable env | grep ABC_IJK[1,2] currenlty defined variables are like this ABC_IJK1=123 ABC_IJK1_XYZ=sn123:345 ABC_IJK2=999 ABC_IJK2_XYZ=sn321:999 I only want to get only this ABC_IJK1=123 ABC_IJK2=999 get number of connections sum them(not 123 + 999) and save in N1 (this one has 2 connection) so N1=2 get number of connections sum them and save in N2 for other machine (if this have four) so N2=4 If the value is not there or the variable is not present then N1=1 for below: ABC_IJK1= ABC_IJK2=123 Then need to compare it with a MAX_CONNECTION variable Thanks

  • Word 2007, Open XML - embedding an image

    - by agnieszka
    Do you know what basic information MUST include a paragraph (w:p) in document.xml inside a *.docx document, that specifies an image? I do know there must be <a:blip r:embed="rId4" /> specifing the relation id, but what else? It's very hard to find it in google and experimenting with cutting out tags from a ready document or reading the specification takes a lot of time. An example with all the required tags would be greatly appreciated.

  • detecting pauses in a spoken word audio file using pymad, pcm, vad, etc

    - by james
    First I am going to broadly state what I'm trying to do and ask for advice. Then I will explain my current approach and ask for answers to my current problems. Problem I have an MP3 file of a person speaking. I'd like to split it up into segments roughly corresponding to a sentence or phrase. (I'd do it manually, but we are talking hours of data.) If you have advice on how to do this programatically or for some existing utilities, I'd love to hear it. (I'm aware of voice activity detection and I've looked into it a bit, but I didn't see any freely available utilities.) Current Approach I thought the simplest thing would be to scan the MP3 at certain intervals and identify places where the average volume was below some threshold. Then I would use some existing utility to cut up the mp3 at those locations. I've been playing around with pymad and I believe that I've successfully extracted the PCM (pulse code modulation) data for each frame of the mp3. Now I am stuck because I can't really seem to wrap my head around how the PCM data translates to relative volume. I'm also aware of other complicating factors like multiple channels, big endian vs little, etc. Advice on how to map a group of pcm samples to relative volume would be key. Thanks!

  • MS-Excel Negative times

    - by oxinabox.ucc.asn.au
    I'm writing a spreadsheet for a shop manager. What it does is keep track of the number of hours a worker has worked. So you enter times for Monday-Sunday, and then an adjustment - e.g. if they work 40/40/40/32 hours for the month, then you would have an adjustment of -2/-2/-2/+6 to bring the worker to the 38 hour week that he's being paid for. Some (most) weeks may be adjusted for overtime. The spreadsheet then totals the hours. This spreadsheet is supposed to just be a self-calculating version of a paper form. It needs to match the paper form as it has to be substituted for the old form which is given to some other member of the company (pay clerk, I don't know; I'm not rebuilding their whole system, just replacing a form) I'm having trouble entering a negative time in the adj field - the field has a [h]:mm formatting. and when i enter a negative time (e.g. -2:00) it displays an error, saying "incorrectly formatted equation", with the suggestion that if I was entering a string then I should prefix with a apostrophe. How do I overcome this?

  • Abusing the word "library"

    - by William Pursell
    I see a lot of questions, both here on SO and elsewhere, about "maintaining common libraries in a VCS". That is, projects foo and bar both depend on libbaz, and the questioner is wondering how they should import the source for libbaz into the VCS for each project. My question is: WTF? If libbaz is a library, then foo doesn't need its source code at all. There are some libraries that are reasonably designed to be used in this manner (eg gnulib), but for the most part foo and bar ought to just link against the library. I guess my thinking is: if you cut-and-paste source for a library into your own source tree, then you obviously don't care about future updates to the library. If you care about updates, then just link against the library and trust the library maintainers to maintain a stable API. If you don't trust the API to remain stable, then you can't blindly update your own copy of the source anyway, so what is gained? To summarize the question: why would anyone want to maintain a copy of a library in the source code for a project rather than just linking against that library and requiring it as a dependency? If the only answer is "don't want the dependency", then why not just distribute a copy of the library along with your app, but keep them totally separate?

  • MS SQL Server: how to optimize "like" queries?

    - by duke84
    I have a query that searches for clients using "like" with wildcard. For example: SELECT TOP (10) [t0].[CLIENTNUMBER], [t0].[FIRSTNAME], [t0].[LASTNAME], [t0].[MI], [t0].[MDOCNUMBER] FROM [dbo].[CLIENT] AS [t0] WHERE (LTRIM(RTRIM([t0].[DOCREVNO])) = '0') AND ([t0].[FIRSTNAME] LIKE '%John%') AND ([t0].[LASTNAME] LIKE '%Smith%') AND ([t0].[SSN] LIKE '%123%') AND ([t0].[CLIENTNUMBER] LIKE '%123%') AND ([t0].[MDOCNUMBER] LIKE '%123%') AND ([t0].[CLIENTINDICATOR] = 'ON') It can also use less parameters in "where" clause, for example: SELECT TOP (10) [t0].[CLIENTNUMBER], [t0].[FIRSTNAME], [t0].[LASTNAME], [t0].[MI], [t0].[MDOCNUMBER] FROM [dbo].[CLIENT] AS [t0] WHERE (LTRIM(RTRIM([t0].[DOCREVNO])) = '0') AND ([t0].[FIRSTNAME] LIKE '%John%') AND ([t0].[CLIENTINDICATOR] = 'ON') Can anybody tell what is the best way to optimize performance of such query? Maybe I need to create an index? This table can have up to 1000K records in production.

  • add ms ajax accordion pane at runtime loses previous pane issue

    - by Chris Conway
    I have an AjaxControlToolkit accordion control that i'm trying to load panes at runtime. When I click a button inside a listview, it should add a new pane to the accordion control. Here is the code that adds the pane in the onitemcommand event within the listview var pane = new AccordionPane { ID = key }; pane.HeaderContainer.Controls.Add(new LiteralControl(label.Text)); pane.ContentContainer.Controls.Add(LoadControl("~/UserControls/Covers/" + e.CommandArgument + ".ascx")); accordion.Panes.Add(pane); And this will successfully show a webcontrol inside the accordion control. But when I click on another button in the listview, the accordion is reset and it only shows the new pane instead of appending a new pane. Is there any way to keep the previous pane visible across postbacks like this? By the way, each of the webcontrols that are loaded in the accordion have input fields that will need to be persisted across postbacks as well. thanks!

  • MS SQL Error: Primary file group is full

    - by aximili
    I have a very large table in my database and I am starting to get this error Could not allocate a new page for database 'mydatabase' because of insufficient disk space in filegroup 'PRIMARY'. Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. How do you fix this error? I don't understand the suggestions there.

  • MS Office SharePoint Server 2007 UI language change

    - by Alexander
    There is an existing app in MOSS, which allows to create polls for a call center, operators fill them out as they call targeted customers. Then this Web app outputs the results of this poll. Is it possible to change the interface language of this existing web app? Operators don't understand English. If it's not about language packs, it would still be easier for me to embed new names and labels, rather than rewrite in a system I am not familiar with. Also, is it possible to change the authentication type from Windows authentication to regular username/password check (username and password will be stored in DB or somewhere only for this site) If it is possible, can you direct me to some kind of tutorial, help or manual which would show how to do it? On MSDN it's written that language can't be changed, but I'm not sure whether it's about the Web app language. Thank you.

  • Why better isolation level means better performance in MS SQL Server

    - by Oleg Zhylin
    When measuring performance on my query I came up with a dependency between isolation level and elapsed time that was surprising to me READUNCOMMITTED - 409024 READCOMMITTED - 368021 REPEATABLEREAD - 358019 SERIALIZABLE - 348019 Left column is table hint, and the right column is elapsed time in microseconds (sys.dm_exec_query_stats.total_elapsed_time). Why better isolation level gives better performance? This is a development machine and no concurrency whatsoever happens. I would expect READUNCOMMITTED to be the fasted due to less locking overhead.

  • Achieve Rails-style migrations in MS Access VBA application

    - by avguchenko
    This is a simple way to do Rails-style migrations in a VBA application. Just add additional migrations like migration(name, sql_string, database) to run_migratons and call run_migrations somewhere in the beginning of your execution. Function migrate(signature As String, sql As String, dbs As DAO.database) Dim rs As DAO.Recordset Set rs = dbs.OpenRecordset("select * from versions where migration = '" & signature & "'") If rs.EOF Then dbs.Execute (sql) rs.AddNew rs("migration") = signature rs.Update End If End Function Function setup_versions(dbs As DAO.database) Dim t As DAO.TableDef On Error Resume Next Set t = dbs.TableDefs("versions") If Err.Number <> 0 Then dbs.Execute ("CREATE TABLE versions (migration text)") End If Err.Clear End Function Function run_migrations(dbs As DAO.database) setup_versions(dbs) migrate("20100315142400_create_table", "CREATE TABLE table_name (field1 type, field 2 type)", dbs) 'add migrations here' End Function

  • MS SQL and .NET Typed Dataset AllowDBNull Metadata

    - by Christian Pena
    Good afternoon, I am generating a typed dataset from a stored procedure. The stored procedure may contain something like: select t1.colA, t2.colA AS t2colA from t1 inner join t2 on t1.key = t2.key When I generate the typed dataset, the dataset knows whether t1.colA allows NULLs, but it always puts FALSE in AllowDBNull for t2.colA even if t2.colA allows NULL. Is this because the column is aliased? Is there any way, from SQL, to hint to VS that the column allows NULL? We currently have to go in and update the column's AllowDBNull if we regenerate the table. Thanks in advance. Christian
