What's the best way of writing robust code so that a variable can be checked for null and blank.
e.g.
string a;
if((a != null) && (a.Length() > 0))
{
//do some thing with a
}
I have a dict of lists in python:
content = {88962: [80, 130], 87484: [64], 53662: [58,80]}
I want to turn it into a list of the unique values
[58,64,80,130]
I wrote a manual solution, but it's a manual solution. I know there are more concise and more elegant way to do this with list comprehensions, map/reduce , itertools , etc. anyone have a clue ?
content = {88962: [80, 130], 87484: [64], 53662: [58,80]}
result = set({})
for k in content.keys() :
for i in content[k]:
result.add(i)
# and list/sort/print just to compare the output
r2 = list( result )
r2.sort()
print r2
As a personal hobby I am looking to build an online audio mixer where I can upload individual instrument tracks, control individual volumes of each track, and export the mixed down version. I've been trying (and have come pretty close) with javascript. I really would like to stay away from flash if possible, but I'm really looking for suggestions for technologies to try. If anyone has any suggestions on languages that are good at stuff like this or libraries that I am missing, please let me know!
I have a test environment that I have been using:
http://driverstestpractice.com/sandbox
Currently all tracks on the site are set to the click track in order to test the track sync (which as you can tell is a little off)!
Thanks!

I've been developing websites for over a decade now, but quickly found that many of my habits in developing for the web are useless when developing for email clients. This has caused me an enormous amount of frustration, so I thought I would ask a question that would hopefully surface the best practices and necessary considerations for others like myself who may find themselves designing for gmail, outlook, etc. from time to time.
Example: <style>...</style> vs inline CSS.
In short: what transfers over from the web-world to the email-world, and what doesn't.
Found the following in an Oracle-based application that we're migrating (generalized):
SELECT
Table1.Category1,
Table1.Category2,
count(*) as Total,
count(Tab2.Stat) AS Stat
FROM Table1, Table2
WHERE (Table1.PrimaryKey = Table2.ForeignKey(+))
GROUP BY Table1.Category1, Table1.Category2
What does (+) do in a WHERE clause? I've never seen it used like that before.
Hi!
I need to retrieve the name, email and picture from a google account.
I am already using the openid to make the user login with it's google acc.
Can I have the picture URL from the openid proccess?
with OAuth I cant'seem to find the right scope to retrieve this information... See this link:
http://code.google.com/apis/gdata/docs/directory.html
there is a list of scopes that you can fetch with REST api to google and I didnt't see the one related to the profile.
Btw, I am using PHP and the openid is already working, but didn't start with the oauth untill I know if I can(and need) retrieve the picture (because email and name already comes within the openid proccess)
thanks,
Joe
Last year I heard that Installer Projects were going away and we should be switching to Windows Installer XML. Whatever happened with that?
So you know where I'm coming from, support for TFS-based buil machines is very important to me. I know Installer Projects kinda-sorta work with TFS, but they have issues.
I have an application that uses CoreData and I'm trying to figure out the best way to implement tagging and filtering by tag. For my purposes, if I was doing this in raw SQLite I would only need three tables, tags, item_tags and of course my items table. Then filtering would be as simple as joining between the three tables where only items are related to the given tags. Quite straightforward.
But, is there a way to do this in CoreData and utilizing NSFetchedResultsController? It doesn't seem that NSPredicate give you the ability to filter through joins. NSPredicate's aren't full SQL anyway so I'm probably barking up the wrong tree there. I'm trying to avoid reimplementing my app using SQLite without CoreData since I'm enjoying the performance CoreData gives me in other areas. Yes, I did consider (and built a test implementation) diving into the raw SQLite that CoreData generates, but that's not future proof and I want to avoid that, too.
Has anyone else tried to tackle tagging/filtering with CoreData in a UITableView with NSFetchedResultsController
I'm using the post-receive-email script included with git. (Source is here.) It works just fine, but I want each email to be sent from the author of the commits pushed. How do I do it?
My post-receive file currently looks like this, and I want to customize the from-email-address.
#!/bin/sh
export [email protected]
$(dirname $0)/post-receive-email
I can get the active window's process, but I have no idea how to get the location of that process, as far as I can see the process object only has ProcessName property which just returns like chrome instead of C:\pathtochrome\chrome.exe
How can I get the latter because I'm trying to get the process's File Description attribute, but I need the full path to it.
I have a variable "fila" with a full line with excel's values; The problem is when in excel I have --#N/A-- vba take that value like "Error 2042" and I cannot asign that value to "valor" and produce me an error, until this point everything is ok, now I am trying to define a "On error goto" for go to the "next" iteration in the loop "for", but I dont know Why vba doesnt handle the error.
Do While Not IsEmpty(ActiveCell)
txt = ActiveCell.Value2
cell = ActiveCell.Offset(0, 1).Value2
fila = Range("C20:F20")
For j = 1 To UBound(fila, 2)
On Error GoTo Siguiente
If Not IsEmpty(fila(1, j)) Then
valor = fila(1, j)
cmd = Cells(1, j + 2).Value2
devolver = function1(cmd, txt, cell, valor)
arrayDevolver(p) = devolver
p = p + 1
End If

Hi there
I am not sure if the title has the correct terms, I have a developer and am very new to cubes.
I have a cube which has data associated to materials that are broken down into chemical compounds.
For example a rock material has 10% of this chemical and 10% of that chemical, etc. Samples are taken daily and sample is a dimension with date, etc.
So, the measure needs to average by the sample dimension but needs to sum across the chemical compound dimension (To add up to 100% for example).
Is this at all possible?
Hi, I'm looping a two-dimensional array like this:
if (!empty($aka)) {
foreach ($aka as $ak) {
if($ak["lang"]=="es") {
$sptitle=$ak["title"];
}
}
}
Pretty simple. If the array ($aka) is not empty I loop trough it and when it finds that the "lang" index is equal to "es" I just save the "title" value for that index in $sptitle.
The problem is that the array ($aka) contains a lot of information and sometimes there is no "lang" index... and I get this error: Notice: Undefined index: lang.
How can I fix this???
This is a extract of the array to help you understand. Notice that [1] doesn't have a [lang] index but [2] does have:
[1] => Array
(
[title] => The Lord of the Rings: The Motion Picture
[year] =>
[country] => USA
[comment] => promotional title
)
[2] => Array
(
[title] => Señor de los anillos: La comunidad del anillo, El
[year] =>
[country] => Argentina
[comment] => Chile, Mexico, Peru, Spain
[lang] => es
)
Thanks!
The alerts that I setup for source code changes isn't being triggered. I suspect that the email server settings are wrong, but where would I configure them?
https://docs.google.com/viewer is awesome, but there are some customizations I need to make, and documentation would be helpful. Discovered here http://googlesystem.blogspot.com... . Haven't seen any public documentation that would help.
http://code.google.com/apis/documents/overview.html covers the Google docs - where the above is more a clone of the Google Books previewer http://books.google.com/books .
Hi,
I've got a problem when I'm calling a static var from another class. I get this pretty syntax error where php is unexpected the '.'
Here is where I'm calling it :
private $aLien = array(
"menu1" => array("Accueil","statique/".Variable_init::$langue."/accueil.html",0,0), //This line
"menu2" => array("Infos Pratiques","statique/".Variable_init::$langue."/info.html",0,0),
"menu3" => array("Faire une réservation","statique/".Variable_init::$langue."/reserver.html",0,0),
"menu4" => array("Pour Nous Joindre","statique/".Variable_init::$langue."/nousJoindre.html",0,0),
"menu5" => array("Plan du site","statique/".Variable_init::$langue."/plansite.html",0,0)
);
And here is my static var declaration from another class:
class Variable_init implements iVariable_init{
public static $langue;
public static $id_choix;
public static $id_contenu;
We're being told that fewer HTTP requests per page load is a Good Thing. The extreme form of that for CSS would be to have a single, unique CSS file per page, with any shared site-wide styles duplicated in each file.
But there's a trade off there. If you have separate shared global CSS files, they can be cached once when the front page is loaded and then re-used on multiple pages, thereby reducing the necessary size of the page-specific CSS files.
So which is better in real-world practice? Shorter CSS files through multiple discrete CSS files that are cacheable, or fewer HTTP requests through fewer-but-larger CSS files?

How can I use touchesbegan in a table's cell without having to subclass a whole cell. Something like addTarget..... which is available for a UIButton?
(in vb.net this would be like AddHandler I think)

Where does one go to report bugs in Google Code? Alas, searching for "Google Code" within "Google Code" is futile as the title of every single project page contains the words "Google Code" -- assuming that Google Code is even self-hosting.
I have an HTML page that needs to open in word. I created the document in word and saved the document as an HTML document. So word spits out all its nasty HTML syntax. This is the opened through internet explorer which will display the word document within the browser.
When I view the page word modifies some of the tags. More specifically it adds a Width and Height tag and ignores the width and height within the style tag. If I try setting the Width and Height tags it overrides with new values. I have tested on different environments and get different results as word makes decision how to handle.
A bit of background this img starts off as this, and is rendered via data rendering syntax.
<asp:Image id="as" runat="server" Src"<%# ImgSource %>" style="width:178px;height:130px" />
It ends up like this in word
<img width=32
height=32 id=barCodeImage
src="http://myurl/BarcodeImages/1136574_129180418198008169.png"
style='border-bottom-width:0px;border-left-width:0px;border-right-width:0px;
border-top-width:0px;height:130px;width:178px'>
I want to stop word from reformatting the HTML.
