Quick question: what is the (full) valid / allowed charset for id and class CSS identifiers?
Is there a regular expression that I can use to validate against? Is it browser agnostic?
Hey,
Quick VHDL question, I don't have access to Xilinx at the moment due to dead laptop, so can't test this.
I was wondering if it's possible to use variables and arithmetic in 'downto' statements, e.g:
proc: process (x)
begin
y <= z(x downto 0) & z(7 downto x);
end process;
Thanks.
Hi Guys, I have a clients website - www.stagecraft.co.uk and they want the navigation on the hire pages (longer page) to still be there at when you scroll the page down. I've had a quick go (not live) with position fixed but in doing so it the leftside navigation is about 200px or so from the top of the window. Any when to get it at the top of the window when scrolling?
Thanks in advance....
Hey folks,
Been messing about with this all day and haven't got anywhere so I'm hoping someone can help me - I have a HeapReAlloc method failing with the error ACCESS_VIOLATION, but I'm unsure how to implement a further check using GetExceptionCode as it uses try/catch or exception or something - can someone give me a quick example of how I can use it to narrow down this failure, please?
Thanks very much,
Becky
The company I work for currently uses some basic functions to abstract the OCI libraries as a means for DB connectivity. We're considering switching to PHP's PDO object, but from some quick searches, it looks like the Oracle driver is a bit less mature than the other PDO drivers. I would appreciate some pro/cons for PDO/Oracle from anyone who has used it in a production environment.
Thanks!
Got to do a quick job in C# which I am a complete noob.
I need to adjust the datetime of a bunch of objects.
I'd like to loop through the properties of the class and if the type is dateTime adjust accordingly.
Is there any kind of 'describe type' built in goodness I can use?
I'm storing several versions of a file based on a digest of the original filename and its version, like this:
$filename = sha1($original . ':' . $version);
Would it be worth it to cache the digest ($filename) in memcache as a key/value pair (the key being the original + version and value the sha1 hash), or is generating the digest quick enough (for a high traffic php web app)?
Thanks,
Johnathan

Whilst answering “Dealing with awful estimates” posted by Ash I shared a few tips that I learned and personally use to spot weak estimates. But I am certain there must be many more!
What heuristics to use in the scenario when one needs to make a quick evaluation of software project estimate that has been compiled by a third-party (a colleague, a business partner or an external company)?
What are the obvious and not so obvious signs of weak software estimates that can be spotted without much detailed knowledge of task at hand?
Hi,
I am doing some benchmarking to determine if I can use WPF for a new product. However, early performance results are disappointing. I made a quick app that uses data binding to display a bunch of random text inside of a list box every 100 ms and it was eating up ~15% CPU. So I made another quick app that skipped the data binding/data template scheme and does nothing but update 10 TextBlocks that are inside of a ListBox every 100 ms (the actual product wouldn't require 100 ms updates, more like 500 ms max, but this is a stress test). I'm still seeing ~10-15% CPU usage. Why is this so high? Is it because of all the garbage strings?
Here's the XAML:
<Grid>
<ListBox x:Name="numericsListBox">
<ListBox.Resources>
<Style TargetType="TextBlock">
<Setter Property="FontSize" Value="48"/>
<Setter Property="Width" Value="300"/>
</Style>
</ListBox.Resources>
<TextBlock/>
<TextBlock/>
<TextBlock/>
<TextBlock/>
<TextBlock/>
<TextBlock/>
<TextBlock/>
<TextBlock/>
<TextBlock/>
<TextBlock/>
</ListBox>
</Grid>
Here's the code behind:
public partial class Window1 : Window
{
private int _count = 0;
public Window1()
{
InitializeComponent();
}
private void OnLoad(object sender, RoutedEventArgs e)
{
var t = new DispatcherTimer(TimeSpan.FromSeconds(0.1), DispatcherPriority.Normal, UpdateNumerics, Dispatcher);
t.Start();
}
private void UpdateNumerics(object sender, EventArgs e)
{
++_count;
foreach (object textBlock in numericsListBox.Items)
{
var t = textBlock as TextBlock;
if (t != null)
t.Text = _count.ToString();
}
}
}
Any ideas for a better way to quickly render text?
My computer: XP SP3, 2.26 GHz Core 2 Duo, 4 GB RAM, Intel 4500 HD integrated graphics. And that is an order of magnitude beefier than the hardware I'd need to develop for in the real product.
Hello,
I am using vim with fugitive extension http://www.vim.org/scripts/script.php?script_id=2975
It has :Gdiff command which brings you into vimdiff mode, but what is the right/quick way to close/quit vimdiff mode?
i.e. let's say I am editing file FooBar.txt under git repository, then firing up :Gdiff, review my changes in vimdiff and want to get back and continue editing FooBar.txt or any other file :)
Thanks.
Just a quick question: is the following PHP code secure? Also is there anything you think I could or should add?
$post = $_GET['post'];
if(is_numeric($post))
{
$post = mysql_real_escape_string($post);
}
else
{
die("NAUGHTY NAUGHTY");
}
mysql_select_db("****", $*****);
$content = mysql_query("SELECT * FROM tbl_***** WHERE Id='" . $post . "'");
Hi all
I've got a web app solution containing a class library project.
Whenever I rebuild the class library and then refresh the page, it takes ages the first time, and is then quick again subsequently.
It's almost as if the newly rebuilt dll is having to 'bed in' to the app.
Can anyone tell me what's really going on behind the scenes?
Thanks
David
Hi everyone,
Quick question here about short-circuiting statements in C#. With an if statement like this:
if (MyObject.MyArray.Count == 0 || MyObject.MyArray[0].SomeValue == 0)
{
//....
}
Is it guaranteed that evaluation will stop after the "MyArray.Count" portion, provided that portion is true? Otherwise I'll get a null exception in the second part.
i dont have a wifi router, so when at home i need to turn my laptop into a wifi source so that both myself and my partner can access the internet.
however during the days i work at a coffee shop and require the use of their wifi.
i'm running snow leopard and i find it stupidly cumbersome to constantly be turning off and on, first internet sharing and then my wifi.
any ideas for a quick n dirty applescript solution?
thanks a bajillion!

Hello, I need to print last 20 characters of string, but only whole words. Delimiter is a space "". Let's consider this example:
string="The quick brown fox jumps over the lazy dog"
echo $string | tail -c20
returns s over the lazy dog. And I need it to return over the lazy dog instead. Do you know how to accomplish that? Thanks!
Is it possible to use PHP magic methods (specifically __get()) outside a defined class?
I'm wanting to use it in a configuration file for quick loading. The configuration file has a single array, $config, with many keys. Therefore, I'd like to override __get() to return the key in the array.
I often find myself doing quick checks like this:
if (! eregi('.php',$fileName))
$filename.='.php';
But sadly eregi() is going to be deprecated in PHP 6, which means all of my code that uses it will be rendered useless :(.
Is there another function that behaves exactly the same way as eregi()? I don't know anything about reg exps and don't want to learn, so preg_match() etc won't work for me.
SQL Server Express does not have the Tasks - Import Data option that other editions of SQL Server has. Has anyone come across a free tool to import data?
I understand I can use the bulk import but I have run into a security issue with it and would like a quick and a dirty way of importing a csv file to a sql express table.
A quick, fun question - What is the difference between a function declaration in C/C++ and an else-if statement block from a purely parsing standpoint?
void function_name(arguments) {
[statement-block]
}
else if(arguments) {
[statement-block]
}
Looking for the best solution! =)
I'm writing a migration to convert a non-rails app into the right format for rails - one of the tables for some reason does not have auto increment set on the id column. Is there a quick way to turn it on while in a migration, maybe with #change_column or something?
Hey everyone,
I am just getting started with the Android SDK and I had a quick question. I am trying to set up a ListView with a rectangle of color on the left and then a bit of text for each row. I also want to make it so I can click each entry in the list and open a new activity to display some information (similar to the contact list). Anyone have any examples to help me out?
Thanks a ton,
Robert Hill
I have the following:
LPSTR email // Has data in it already
LPSTR index=strchr(email,'@');
Now I want to Insert into a new string:
LPSTR username
the part of "email" from the beginning of the string to "index".
For example:
email="[email protected]"
so username="roel" .
Is there a function to do it quick or do I need to build one?
Roel
I can't see to find a quick explanation of the differences so I can figure out which to use.
One is for a server one is for a Database? Im not sure what that means..
Basically we are doing a new web app and I want to see what these project types can offer me in terms of tracking the DB code/schema etc..
Hi, I'm looking to write a quick program to read and inspect packets of a certain format and then blacklist ips with a certain style of packet-traffic (packet patterns of an attack against the network). Are there decent samples of reading and inspecting packet flow on a network?
