  • Server is on or off

    - by Daniel
    Curious. I'm starting to broadcast high school football games online, and it uses a program to broadcast the feeds off my computer. However, when I shut the program down or the computer down, the server goes offline and guests won't be able to access the feeds. Is there any kind of code out there that I can post onto my website that will indicate to my guests whether the server is on or off? I would figure it would be a simple code, a php script or something that periodically checks to see if a site is on line and then displays ON or OFF.

  • Excel VBA - export to UTF-8

    - by Tom
    The macro I created works fine, I just need to sort out the saving business. Now I get a popup asking me where to save it, but I would like it to save it under a default name and path AND encoded in UTF-8. This is my full code I use, the bottom part saves the document I presume. Public Sub ExportToTextFile(FName As String, Sep As String, SelectionOnly As Boolean, AppendData As Boolean) Dim WholeLine As String Dim fnum As Integer Dim RowNdx As Long Dim ColNdx As Integer Dim StartRow As Long Dim EndRow As Long Dim StartCol As Integer Dim EndCol As Integer Dim CellValue As String Dim teller As Integer 'Teller aangemaakt ter controle voor het aantal velden 'teller = 1 Application.ScreenUpdating = False On Error GoTo EndMacro: fnum = FreeFile If SelectionOnly = True Then With Selection StartRow = .Cells(1).Row StartCol = .Cells(26).Column EndRow = .Cells(.Cells.Count).Row EndCol = .Cells(.Cells.Count).Column End With Else With ActiveSheet.UsedRange StartRow = .Cells(1).Row StartCol = .Cells(26).Column EndRow = .Cells(.Cells.Count).Row EndCol = .Cells(26).Column End With End If If AppendData = True Then Open FName For Append Access Write As #fnum Else Open FName For Output Access Write As #fnum End If For RowNdx = StartRow To EndRow WholeLine = "" For ColNdx = StartCol To EndCol If Cells(RowNdx, ColNdx).Value = "" Then CellValue = "" Else CellValue = Cells(RowNdx, ColNdx).Value End If WholeLine = WholeLine & CellValue & Sep Next ColNdx WholeLine = Left(WholeLine, Len(WholeLine) - Len(Sep)) Print #fnum, WholeLine, "" 'Print #fnum, teller, WholeLine, "" 'teller = teller + 1 Next RowNdx EndMacro: On Error GoTo 0 Application.ScreenUpdating = True Close #fnum End Sub Sub Dump4Mini() Dim FileName As Variant Dim Sep As String FileName = Application.GetSaveAsFilename(InitialFileName:=Blank, filefilter:="Text (*.txt),*.txt") If FileName = False Then Exit Sub End If Sep = "|" If Sep = vbNullString Then Exit Sub End If Debug.Print "FileName: " & FileName, "Separator: " & Sep ExportToTextFile FName:=CStr(FileName), Sep:=CStr(Sep), SelectionOnly:=False, AppendData:=False End Sub

  • Which is better? OpenCyc or ConceptNet?

    - by Daniel Loureiro
    Hi, I'm doing a NLP project where I need to recognise concepts in sentences to find other similar concepts. I do this to infer word valences from a list I already have. I started using WordNet, but it gave many contradictory results. By contradictory results I mean word expansions that had contradictory valences. So now I'm looking into ConceptNet and OpenCyc. I've already implemented ConceptNet and it was all very easy and I love it. Problem is that OpenCyc appears to have a much larger and more logically rigid database, which is important when I found so many "contradictions" on WordNet... But I wouldn't know because I haven't tried it. Could someone tell me if it's worth going through the (considerable, for me) effort to implement OpenCyc, or is ConceptNet good enough to infer word valences? Are they that different? I'll be happy to explain myself further, if needed. Trying to keep it short for now! Thanks!

  • How to enable i18n from within setup_app in websetup.py ?

    - by daniel
    From within the setup_app function (websetup.py) of a pylons i18n application, which is making use of a db, I was trying to initiate multilingual content to be inserted into the db. To do so the idea was something like: necessary imports here def setup_app(command, conf, vars): .... for lang in langs: set_lang(lang) content=model.Content() content.content=_('content') Session.add(content) Session.commit() Unfortunately it seems that it doesn't work. the set_lang code line is firing an exception as follows: File ".. i18n/translation.py", line 179, in set_lang translator = _get_translator(lang, **kwargs) File ".. i18n/translation.py", line 160, in _get_translator localedir = os.path.join(rootdir, 'i18n') File ".. /posixpath.py", line 67, in join elif path == '' or path.endswith('/'): AttributeError: 'NoneType' object has no attribute 'endswith' Actually I'm even not sure it could be possible launching i18n mechanisms from within this setup_app function without an active request object. Anyone has tried some trick on a similar story ?

  • Make is more OOPey - good structure?

    - by Tom
    Hi, I just want advice on whether I could improve structure around a particular class which handles all disk access functions The structure of my program is that I have a class called Disk which gets data from flatfiles and databases on a, you guessed it, hard disk drive. I have functions like LoadTextFileToStringList, WriteStringToTextFile, DeleteLineInTextFile etc which are kind of "generic methods" In the same class I also have some more specific methods such as GetXFromDisk where X might be a particular field in a database table/query. Should I separate out the generic methods from the specialised. Should I make another class which inherits the generic methods. At the moment my class is static as there is no need to have an internal state of the class. I'm not really OOPing am I? Thanks Thomas

    I'm studying security, and I would like to know: in Windows or Unix based OS environment, is there a way for a malicious program to copy all the content of the computer's memory? My worry is about a program that can get my decrypted data loaded in memory. And how to avoid it.

  • Finding the left-most and right-most points of a list. std::find_if the right way to go?

    - by Tom
    Hi, I have a list of Point objects, (each one with x,y properties) and would like to find the left-most and right-most points. I've been trying to do it with find_if, but i'm not sure its the way to go, because i can't seem to pass a comparator instance. Is find_if the way to go? Seems not. So, is there an algorithm in <algorithm> to achieve this? Thanks in advance. #include <iostream> #include <list> #include <algorithm> using namespace std; typedef struct Point{ float x; float y; } Point; bool left(Point& p1,Point& p2) { return p1.x < p2.x; } int main(){ Point p1 ={-1,0}; Point p2 ={1,0}; Point p3 ={5,0}; Point p4 ={7,0}; list <Point> points; points.push_back(p1); points.push_back(p2); points.push_back(p3); points.push_back(p4); //Should return an interator to p1. find_if(points.begin(),points.end(),left); return 0; }

  • How do I disable auto-compilation of Scala source in jEdit?

    - by Daniel
    I have always liked the auto-compilation feature of jEdit with Scala sources. Now, however, I'm using "mvn scala:cc" and JavaRebel with a Lift project, which provides better compilation than what jEdit does, and I'd like to disable jEdit's auto-compilation. How do I disable auto-compilation in jEdit, of Scala sources, in particular?

  • Direct show video renderers suck?

    - by Daniel
    So I've been looking into the world of media playback for windows and I've started making a C# Media Player using DirectShow. I started off using the VRM-7 windowed video renderer and it was brilliant except it had a couple of small problems (multi monitors, fullscreen). But after some research I found that it's deprecated and I should be using VRM9. So I changed it to use VRM9 windowless then found out that was an old post rofl _< so finally I'm using Vista/Win7 (or XP .net 3) Enhanced Video Renderer (EVR) which is apparently the most up to date Microsoft video renderer and has all the flashy performance/quality things added to it. (tbh I haven't noticed any difference but maybe I need a blue-ray or HQ video to notice it). With using EVR everything is working fine except resizing the video. Its really laggy/choppy/teary and problem something to do with its frame queueing mechanism. To demonstrate my problem open up windows media player classic. View - Options - Playback - output Chose the "EVR" DirectShow Video renderer Now restart wmp class and play a video, while it's playing click and drag a corner to resize it. You'll notice its horribly laggy. This is the exact same problem i am having. But if you chose "EVR Custom Pres. *" or EVR Sync *" resizing works beautifully! So i tried googling around for anything about EVR resizing issues and how to fix it but i couldn't believe how little i could find. I'm guessing "Custom Pres." stands for "Custom Presenter" which sounds like they made their own. Also you'll notice on the right hand size when you swap between EVR and the other EVR's the Resizer drop down on the right greys out. So basically I wan't to know how I can fix this retarded resizing problem and is there any decent documentation out there? There is a fair bit for VMR7/9 but not much for EVR. I downloaded the DirectX SDK which apparently has samples but it was a waste of 500mb of bandwidth as it had nothing relevant. Perhaps there is some way to force it not queueing up frames if that is the problem? If you want code say the word and I'll paste some in. But it's really quite simple and nothing much happens, i'm convinced it's a problem with the EVR renderer. EDIT: Oh and one other thing, what does VLC use? If you go into vlc options and change the renderer to anything but default, they all suck. So is it using VMR7? Or its own?

  • MySQL: Blank row in table after LOAD DATA INFILE

    - by Tom
    Hi, I'm uploading a large amount of data from a CSV (I'm doing it via MySQL Workbench): LOAD DATA INFILE 'C:/development/mydoc.csv' INTO TABLE mydatabase.mytable CHARACTER SET utf8 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r'; However, I'm noticing that it keeps adding an empty line full of nulls/zeros after the last record. I'm guessing it's because of the "LINES TERMINATED" command. However, I need that to load the data in correctly. Is there some way around this / some better SQL to avoid the blank row in the table? Thanks

  • What is reading source on an ebook reader like?

    - by Daniel Straight
    There are a few open source projects I would really like to read through the code of to understand better / improve on. The problem is, for me, reading for a long time on the computer screen is tedious. I would love to be able to read code while lounging around and on a screen that was better on my eyes. Has anyone ever tried reading code on an ebook reader? It seems like the e-ink would make it easy on the eyes, plus it would be portable, plus it wouldn't kill any trees. In other words, it sounds perfect, but before I drop a couple benjamins on an ebook reader, I'd like to hear if anyone else has tried this and how it went. It seems Scott Hanselman discussed using the Kindle to read code, but I wouldn't necessarily want a Kindle. Has anyone had a positive experience with some other device? I realize this is not directly about programming, but it relates directly to my ability to improve my skills. I think if a good portable reading device for code exists, it could help a lot of programmers.

  • Run JavaScript after a DropDownList is DataBound

    - by Daniel Coffman
    I need to trigger a JavaScript function to be called AFTER a DropDownList on my ASP.NET WebForms page is DataBound, because the SelectedIndex of this DropDownList is the parameter to the JavaScript function. I've tried this various ways, but it seems that if I do it with pure JavaScript onload by using ClientScript.RegisterStartUpScript, the control can be found (because it hasn't been assigned a clientID yet?). If I use jQuery (document).ready { } it says that the DropDownList has no selectedIndex.value. So I need some JavaScript to run AFTER the control has a value set by the DataBind. How can I accomplish this? onChanged won't work because I need the function to fire on the first page load, with no user input. DataBinding the SelectedIndex of the DropDownList doesn't cause the JavaScript onChanged event to fire.

  • PHP session permission problem

  • is JsonP working with Opera, Chrome & Safari ?

    - by Tom
    Hi, On a web site that I am building , when you log in (because the database is on an other server), I use json padding to check if the user as the right credentials. It's working flawlessly (ie7,ie8 & FF), until I tried it on chrome, safari & opera where it's a complete disaster. $.ajax({ type: "GET", dataType: "jsonp", url: "http://someurl.com", data: aRequestData, cache: false, error: function (XMLHttpRequest, textStatus, errorThrown) { // typically only one of textStatus or errorThrown // will have info alert("Error occured textStatus=" + textStatus + " errorThrown=" + errorThrown); }, success: function(data) { alert('success'); } }); Plain and simple and it works in browser window, however, to my big surprise it did not work in chrome, safari & opera, never got to the success alert. Does anyone know how to solve this issue? Thanks.
