• Converting HTML special characters into their value using Python

  - by tipu

  I have a file that's littered with these: http://www.utexas.edu/learn/html/spchar.html That link just displays all sorts of HTML entities, such as – &ndash; — &mdash; ¡ &iexcl; and so on. Is it possible in Python to natively convert these characters back into their values so any occurrences of &ndash; will appear as – instead? My current approach was just to make a dict of key html entities and their utf-8 values and do search and replace, but I was wondering if there are any libraries that can take care of this for me.

• Using Accelerometer in Wiimote for Physics Practicals

  - by Omar

  I have to develop some software in my school to utilize the accelerometer in the Wiimote for recording data from experiments, for example finding the acceleration and velocity of a moving object. I understand how the accelerometer values will be used but I am sort of stuck on the programming front. There is a set of things that I would like to do: Live streaming of data from the Wiimote via bluetooth Use the accelerometer values to find velocity and displacment via integration Plot a set of results Avoid the use of the infrared sensor on the Wiimote Please can anyone give me their thoughts on how to go about this. Also it would be great if people could direct me to existing projects that utizlise the wiimote. Also can someone suggest what would be the best programming language to use for this. My current bet is on using Visual basic. Any sort of help is greatly appretiated.

• Excel UDF calculation should return 'original' value

  - by LeChe

  Hi all, I've been struggling with a VBA problem for a while now and I'll try to explain it as thoroughly as possible. I have created a VSTO plugin with my own RTD implementation that I am calling from my Excel sheets. To avoid having to use the full-fledged RTD syntax in the cells, I have created a UDF that hides that API from the sheet. The RTD server I created can be enabled and disabled through a button in a custom Ribbon component. The behavior I want to achieve is as follows: If the server is disabled and a reference to my function is entered in a cell, I want the cell to display Disabled If the server is disabled, but the function had been entered in a cell when it was enabled (and the cell thus displays a value), I want the cell to keep displaying that value If the server is enabled, I want the cell to display Loading Sounds easy enough. Here is an example of the - non functional - code: Public Function RetrieveData(id as Long) Dim result as String // This returns either 'Disabled' or 'Loading' result = Application.Worksheet.Function.RTD("SERVERNAME", "", id) RetrieveData = result If(result = "Disabled") Then // Obviously, this recurses (and fails), so that's not an option If(Not IsEmpty(Application.Caller.Value2)) Then // So does this RetrieveData = Application.Caller.Value2 End If End If End Function The function will be called in thousands of cells, so storing the 'original' values in another data structure would be a major overhead and I would like to avoid it. Also, the RTD server does not know the values, since it also does not keep a history of it, more or less for the same reason. I was thinking that there might be some way to exit the function which would force it to not change the displayed value, but so far I have been unable to find anything like that. Any ideas on how to solve this are greatly appreciated! Thanks, Che EDIT: By popular demand, some additional info on why I want to do all this: As I said, the function will be called in thousands of cells and the RTD server needs to retrieve quite a bit of information. This can be quite hard on both network and CPU. To allow the user to decide for himself whether he wants this load on his machine, he or she can disable the updates from the server. In that case, he or she should still be able to calculate the sheets with the values currently in the fields, yet no updates are pushed into them. Once new data is required, the server can be enabled and the fields will be updated. Again, since we are talking about quite a bit of data here, I would rather not store it somewhere in the sheet. Plus, the data should be usable even if the workbook is closed and loaded again.

• how to check whether for each value in array is a numeric, alphabetical or alphanumeric (Perl)

  i have array which values are user input like: aa df rrr5 4323 54 hjy 10 gj @fgf %d would be that array, now i want to check each value in array whether its numeric or alphabetic (a-zA-Z) or alphanumeric and save them in other respective arrays i have done: my @num; my @char; my @alphanum; my $str =<>; my @temp = split(" ",$str); foreach (@temp) { print "input : $_ \n"; if ($_ =~/^(\d+\.?\d*|\.\d+)$/) { push(@num,$_); } } this works, similarly i want to check for alphabet, and alphanumeric values note: alphanumeric ex. fr43 6t$ $eed5 *jh

• after XOR operation find C (and XOR reversability)

  - by Jason z

  Assume: unsigned char A = 10; unsigned char B = 11; unsigned char C = 12; unsigned char Diff1 = A ^ B; unsigned char Diff2 = B ^ C; //find any of A or B or C using Diff1 and Diff2 Question is: There were 3 values initially for which we found 2 differences. Is there any way we can find any if A or B or C using 2 differences Diff1 and Diff2? I know XOR is not reversible unless you know the key, but keeping in view that unsigned __int8 is 0...255 maximum 256 different values. stay well.

• T-SQL out of order insert

  - by tearman

  Basically I have a User-Defined Table Type (for use as a table-valued variable) which I'm referencing in a stored procedure that effectively just calls two other stored procedures, then inserts those values into the table type. Id est INSERT INTO @tableValuedVariable (var1, var2, var3, var4, var5) EXEC [dbo].StoredProcedure1; INSERT INTO @tableValuedVariable (var1, var2, var5) EXEC [dbo].StoredProcedure2; You can probably already tell what I'm going to ask. Basically StoredProcedure2 only returns a few of the values the table is set to hold, and I'd like those other variables to just be null (as defined as default). Only SQL is complaining that I'm not specifying all the variables available to that table. The return datasets can be quite sizable so I'd like to avoid loops and such for obvious reasons. Thanks for any help.

• Build a LEGO Creation without Leaving Your Cube

  - by Jason Fitzpatrick

  Just because you’re stuck at your desk doesn’t mean you can’t sneak in a little fun. At BuildWithChrome you can slap together virtual LEGO bricks with ease. The site, a collaboration between Google and LEGO, shows you a massive map of Australia and New Zealand covered in thousands of LEGO base plates. Zoom in, select a base plate, and get building. The block selection is fairly limited (you can work with the kind of blocks you’d find in a generic LEGO brick pack) but it’s still quite a bit of fun. When I took it for a test drive, I started simple by building a house-like structure: With the addition of a few more pieces it would be possible to pull off the wizard shop my wife and daughter just built: How to Banish Duplicate Photos with VisiPic How to Make Your Laptop Choose a Wired Connection Instead of Wireless HTG Explains: What Is Two-Factor Authentication and Should I Be Using It?

• Download attachment issue with IE6-8 - non ssl

  - by Arun P Johny

  I'm facing an issue with file download with IE6-8 in non ssl environment. I've seen a lot of articles about the IE attachment download issue with ssl. As per the articles I tried to set the values of Pragma, Cache-Control headers, but still no luck with it. These are my response headers Cache-Control: private, max-age=5 Date: Tue, 25 May 2010 11:06:02 GMT Pragma: private Content-Length: 40492 Content-Type: application/pdf Content-Disposition: Attachment;Filename="file name.pdf" Server: Apache-Coyote/1.1 I've set the header values after going through some of these sites KB 812935 KB 316431 But these items are related to SSL. I've checked the response body and headers using fiddler, the response body is proper. I'm using window.open(url, "_blank") to download the file, if I change it to window.open(url, "_parent") or change the "Content-Disposition" to 'inline;Filename="file name.pdf"' it works fine. Please help me to solve this problem

• Is it possible to dynamically add webcontrols via jQuery???

  - by Chris Conway

  Currently I have a webform that has a series of links. What I'd like to be able to do is add a webcontrol's content when one of the links is clicked. Is this kind of thing even possible? If not, what's the best strategy for loading a set of controls (one textbox and one dropdown with values from one link, two textboxes and a checkbox from another link, etc.). I'd need to be able get the values of each of these controls on postback. Ideally, I'd like to be able to add that new content to an acordian control, most likely the jQuery UI acordian. So each clickable link would add new content to an acordian control. What's everybody's thoughts on this?

• Array merging/manipulation with Velocity

  - by Razor

  Hello, I have an array set inside a velocity template that contains some paths. The idea is to put a few "default" .js/.css files that 90% of the pages will use in this array. However, the other pages will still have to be able to add/delete values from this array, in case there are no linked files at all, or I need to add some. Given this code: #set ( $head.scripts = [ "https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js", "https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.0/jquery-ui.min.js" ] ) #foreach ($URI in $head.scripts) <script type="text/javascript" src="$URI"></script> #end is there any way to add/delete values from these defaults? I have seen this list tool, but it looks like it's not enough for what I need.

• Remove kubuntu-desktop from ubuntu 12.04 [closed]

  Possible Duplicate: How to completely remove desktop? So, I thought I managed to remove KDE completely, but apparently that did not work at all, because every KDE application is back, including the KDE splash screen. I ran sudo apt-get autoremove --purge kubuntu-desktop Then I ran sudo apt-get install --reinstall ubuntu-desktop Then I ran sudo sudo update-alternatives --config default.plymouth Then I rebooted and everything seemed to be the original ubuntu-desktop (without the kde splash screen and other KDE applications). But now, one week later I still boot to ubuntu-desktop, but like I said, the kde splash screen and applications are all back. How should I remove kubuntu-desktop?

• Why get dedicated hosting? [closed]

  - by user176105

  Possible Duplicate: How to find web hosting that meets my requirements? I just finished writing a website and I'm about to publish it. I was looking at hosting options and I was about to get regular hosting from godaddy, which is about $6 a month with unlimited bandwidth, 150 gb of data, 500 emails and 25 mysql databases. The other option is dedicated servers, which range a lot in price, but are around $200 a month. Why would someone choose dedicated servers? Is it becuase they max the limits of regular hosting or is it because the ram/cpu is shared on regular hosting? If the latter, what will happen if a lot of users come to my site and max the ram/cpu?

• What is 'lack of original content'?

  - by JVerstry

  It is written everywhere that lack of original content is has a negative impact on ranking. But what is lack of original content? (I am not talking about duplicate content) I guess if you copy other site's content, this makes sense. But, assuming one develops its own functionalities, but similar functionalities are already available on other sites, is this considered lack of original content? Can Google decide to not index such pages (i.e., not give them a chance at all)? Are there other definition of 'lack of original content'?

• Make UILabel show "No results" instead of "nan"

  - by Mike Rychev

  I have a small app, where user can make some calculations and solve equations. For example, if in a square equation discriminant is less than zero, the x1 and x2 values are "nan", so when I assign x1 and x2 values to UILabels they show "nan" as well. Writing a lot of if's like if(D<0) [label setText:[NSString stringWithFormat: @"No solutions"]]; Doesn't help-there are too many cases. I want to check if after [label setText:[NSString stringWithFormat: @"%f", x]]; label's value is "nan", the label's value will be set to @"No solutions". Doing simple if(label==@"nan") { //code } doesn't help. Thanks in advance!

• Prevent query string manipulation by adding a hash?

  - by saille

  To protect a web application from query string manipulation, I was considering adding a query string parameter to every url which stores a SHA1 hash of all the other query string parameters & values, then validating against the hash on every request. Does this method provide strong protection against user manipulation of query string values? Are there any other downsides/side-effects to doing this? I am not particularly concerned about the 'ugly' urls for this private web application. Url's will still be 'bookmarkable' as the hash will always be the same for the same query string arguments. This is an ASP.NET application.
