Uninstalled server 2008 now router won't handle DHCP
My set up is this. server behind router, router has a server and switch
connected to it with multiple computers. router used to serve DHCP and
DNS, a couple of days ago installed AD, DNS and DHCP on the server, and
the server gave out IP's.
For various reasons we had to uninstall the domain on our server. I
removed AD, DHCP and DNS from the roles and set the router back to serving
DHCP and DNS. Now I can't get computers on the network. I reset my router
back to factory defaults, and if I plug a computer directly into the
router I can get a IP address, but all the computers behind the switch
can't get an IP address and can't see the router. All my computers say
unidentified network, and if I ping the router it says host is
unreachable.
On the other hand, my wireless devices are just fine and connect no
problem. But for desktops, ipconfig /release doesn't release anything and
/renew can't find a server to renew on. My router log shows several FIN
scans but they are from innocuous websites (google, netgear) and it shows
a couple of smurf attacks but they are all from my external IP. Any ideas?
the server isn't even connected to the route right now, and all the
computers are set for dynamic IP addresses.. I don't know what else to
try? Any help?

Emmet plugin in Sublime Text 2 with Soy Templates
Emmet plugin in Sublime Text 2 with Soy Templates
Has anyone gotten the Emmet plugin to work with Soy Templates in Sublime
Text 2? I tried following the recommendation here:
http://docs.emmet.io/customization/syntax-profiles/ and added a
syntaxProfiles.json file with the following:
{ "SoyTemplate": "html" }
but that didn't do anything.
Any advice would be tremendously appreciated. Thank you.

What is the convenience method to compare two NSNumbers with float values using limited precision?
What is the convenience method to compare two NSNumbers with float values
using limited precision?
What is the Objective-C convenience method for comparing a couple of
NSNumbers with float values to see if they are roughly equivalent (two
decimal places of precision is fine)?
I would use something other than floats if there was an option that did
not change the number around randomly. But anyway I'm already using floats
so... .
I imagine there must be something like:
[myNumber isEqualTo:myOtherNumber withPrecision:2];
But actually, amazingly I can't find such a convenience method. What am I
missing here?
Would it help to cast the two numbers to NSDecimal or something?

Connecting to host from Android via USB
Connecting to host from Android via USB
Okay so here is the background of this problem. I commute a lot on the
train and build a lot of PHP web apps optimized for mobile devices. I
would like to develop code on a netbook (Running Ubuntu Server) with no
GUI. All development done using Vim directly on the netbook.
I would like to connect up my Nexus 4 to the netbook via USB and "connect"
to the netbooks web server in the chrome browser. I can only use USB for
this since I won't be having any reliable internet access.
I understand that using adb from the Android SDK, you can forward a port
from the netbook to the phone. However, I need to do it the other way
around.
For example:
Run a web server on the netbook on port 4000
Connect phone via USB
Somehow forward port 4000 on the phone to port 4000 on the netbook
Open chrome browser on phone and go to localhost:4000.
I am aware of the "reverse port forwarding" method that is described in
the Google docs at
https://developers.google.com/chrome-developer-tools/docs/remote-debugging.
However, this requires an installation of chrome on the netbook. I don't
want to have to install an entire GUI just for this.

jQuery: hide/ show + change text clicking the same class
I have a group of words that on click should show and hide elements. In
addition, I need to change that first group of words. So if it gets
clicked, it shows the container with content + gets changed to hide. In
alternative, when it is clicked again, it should hide the content and
become 'show' again.
<div class="hide-show-button">Click Here to <span
id="hide-show-changed">Show</span></div>
<div class="hide-show">

Finding the first point of great circle Intersection
Finding the first point of great circle Intersection
I have a problem I've been trying to solve and I cannot come up with the
answer. I have written a function in Matlab which, given two lat/lon
points and two bearings, will return the two great circle points of
intersection.
However, what I really need is the first great circle point of
intersection along the two initial headings. I.e. if two airplanes begin
at lat/lon points 1 and 2, with initial bearings of bearing1 and bearing2,
which of the two great circle intersection points is the first one they
encounter? There are many solutions (using haversine) which will give me
the closer of the two points, but I don't actually care about which is
closer, I care about which I will encounter first given specific start
points and headings. There are many cases where the closer of the two
intersections is actually the second intersection encountered.
Now, I realize I could do this with lots of conditional statements for
handling the different cases, but I figure there's got to be a way to
handle it with regard to the order I take all my cross products (function
code given below), but I simply can't come up with the right solution! I
should also mention that this function is going to be used in a large
computationally intensive model, and so I'm thinking the solution to this
problem needs to be rather elegant/speedy. Can anyone help me with this
problem?
The following is not my function code (I can't list that here), but it is
the pseudo code that my function was based off of:
%Given inputs of lat1,lon1,Bearing1,lat2,lon2,Bearing2:
%Calculate arbitrary secondary point along same initial bearing from first
%point
dAngle = 45;
lat3 = asind( sind(lat1)*cosd(dAngle) +
cosd(lat1)*sind(dAngle)*cosd(Bearing1));
lon3 = lon1 + atan2( sind(Bearing1)*sind(dAngle)*cosd(lat1),
cosd(dAngle)-sind(lat1)*sind(lat3) )*180/pi;
lat4 = asind( sind(lat2)*cosd(dAngle) +
cosd(lat2)*sind(dAngle)*cosd(Bearing2));
lon4 = lon2 + atan2( sind(Bearing2)*sind(dAngle)*cosd(lat2),
cosd(dAngle)-sind(lat2)*sind(lat4) )*180/pi;
%% Calculate unit vectors
% We now have two points defining each of the two great circles. We need
% to calculate unit vectors from the center of the Earth to each of these
% points
[Uvec1(1),Uvec1(2),Uvec1(3)] = sph2cart(lon1*pi/180,lat1*pi/180,1);
[Uvec2(1),Uvec2(2),Uvec2(3)] = sph2cart(lon2*pi/180,lat2*pi/180,1);
[Uvec3(1),Uvec3(2),Uvec3(3)] = sph2cart(lon3*pi/180,lat3*pi/180,1);
[Uvec4(1),Uvec4(2),Uvec4(3)] = sph2cart(lon4*pi/180,lat4*pi/180,1);
%% Cross product
%Need to calculate the the "plane normals" for each of the two great
%circles
N1 = cross(Uvec1,Uvec3);
N2 = cross(Uvec2,Uvec4);
%% Plane of intersecting line
%With two plane normals, the cross prodcut defines their intersecting line
L = cross(N1,N2);
L = L./norm(L);
L2 = -L;
L2 = L2./norm(L2);
%% Convert normalized intersection line to geodetic coordinates
[lonRad,latRad,~]=cart2sph(L(1),L(2),L(3));
lonDeg = lonRad*180/pi;
latDeg = latRad*180/pi;
[lonRad,latRad,~]=cart2sph(L2(1),L2(2),L2(3));
lonDeg2 = lonRad*180/pi;
latDeg2 = latRad*180/pi;

The following is not my function code (I can't list that here), but it is
the pseudo code that my function was based off of:
%Given inputs of lat1,lon1,Bearing1,lat2,lon2,Bearing2:
%Calculate arbitrary secondary point along same initial bearing from first
%point
dAngle = 45;
lat3 = asind( sind(lat1)*cosd(dAngle) +
cosd(lat1)*sind(dAngle)*cosd(Bearing1));
lon3 = lon1 + atan2( sind(Bearing1)*sind(dAngle)*cosd(lat1),
cosd(dAngle)-sind(lat1)*sind(lat3) )*180/pi;
lat4 = asind( sind(lat2)*cosd(dAngle) +
cosd(lat2)*sind(dAngle)*cosd(Bearing2));
lon4 = lon2 + atan2( sind(Bearing2)*sind(dAngle)*cosd(lat2),
cosd(dAngle)-sind(lat2)*sind(lat4) )*180/pi;
%% Calculate unit vectors
% We now have two points defining each of the two great circles. We need
% to calculate unit vectors from the center of the Earth to each of these
% points
[Uvec1(1),Uvec1(2),Uvec1(3)] = sph2cart(lon1*pi/180,lat1*pi/180,1);
[Uvec2(1),Uvec2(2),Uvec2(3)] = sph2cart(lon2*pi/180,lat2*pi/180,1);
[Uvec3(1),Uvec3(2),Uvec3(3)] = sph2cart(lon3*pi/180,lat3*pi/180,1);
[Uvec4(1),Uvec4(2),Uvec4(3)] = sph2cart(lon4*pi/180,lat4*pi/180,1);
%% Cross product
%Need to calculate the the "plane normals" for each of the two great
%circles
N1 = cross(Uvec1,Uvec3);
N2 = cross(Uvec2,Uvec4);
%% Plane of intersecting line
%With two plane normals, the cross prodcut defines their intersecting line
L = cross(N1,N2);
L = L./norm(L);
L2 = -L;
L2 = L2./norm(L2);
%% Convert normalized intersection line to geodetic coordinates
[lonRad,latRad,~]=cart2sph(L(1),L(2),L(3));
lonDeg = lonRad*180/pi;
latDeg = latRad*180/pi;
[lonRad,latRad,~]=cart2sph(L2(1),L2(2),L2(3));
lonDeg2 = lonRad*180/pi;
latDeg2 = latRad*180/pi;

Old data gets wiped from POST when I use GET
Old data gets wiped from POST when I use GET
So I am having an issue. I used POST to send data to a new page. I use get
to send data to a function but it seems the POST data get wiped. Here some
code to help explain.
POST CODE to send to form vieworder (works perfect!)
<form method="post" action="vieworder.php">
<input type="hidden" name ="user_id" value="<?php echo
$_SESSION['user_id']; ?>">
<input type="hidden" name ="id" value="<?php echo $data1[$x]['id']; ?>">
<input type="submit" name="submit" value="View"> </td>
</form>
So on the vieworder page I want used to be able to update the data using
this form. This form works as well except i need that value "id" from the
orginal post. It works and the "id"has the data until I use this form.
<form name="approveform" method="get" action="">
Index Number*: <input type="text" name="IndexNum">
<input type="submit" value="Approve" action="">
</form>
I would also prefer to use the POST method but using GET was my first
solution to no deleting the data from POST.
Anyways I then just send the data to a function to update two fields.
Any way to get correct the code?

Is this a javascript method or property?
Is this a javascript method or property?
I'm having the hardest time getting my terminology right. In the following
code:
Notes.NotesController = Ember.ArrayController.extend({
newNoteName: null,
actions: {
createNewNote: function() {
var content = this.get('content');
var newNoteName = this.get('newNoteName');
var unique = newNoteName != null && newNoteName.length > 1;
content.forEach(function(note) {
if (newNoteName === note.get('name')) {
unique = false; return;

});
if (unique) {

newNote.save();
this.set('newNoteName', null);
} else {
alert('Note must have a unique name of at least 2 characters!');
}
}
}
});
What is 'newNoteName:', 'actions:', and 'createNewNote:'?
Are they methods or properties or hooks? What are the differences? And
does 'createNewNote' being nested inside of 'actions:' make 'actions'
something altogether different?
What is the difference between ember 'hooks' and methods/properties that
you create and name yourself and how they're used?

Debugging into Source Code in Eclipse
Debugging into Source Code in Eclipse
In Eclipse, I have created a 'DemoApp' in Android. Also, I have Android
platform source code in Eclipse 'PlatformCode'.
While debugging DemoApp, I want it to use 'PlatformCode' which i have
built using 'make'. I mentioned the name of my source code project in
'Project References' of app project. But, it is not working. How would I
achieve it? 'PlatformCode' is a Java project and it is not having the
conventional Java Project structure in Eclipse like - src folder and other
references, maybe that's why it is showing red exclamation sign on it.

Hyperlink tag inside paragraph and text-align:center
Hyperlink tag inside paragraph and text-align:center
<div style="width:400px">
<p style="text-align:center">
<a>
<img src"..." />
</a>
Some text..
</p>
</div>
So the goal here is to center the image inside the div. Text-align:center
works on the images that are not inside the hyperlink tag, but once they
are, it doesn't affect them, just the text.
I don't want to go with display:block and margin-left/right auto, simply
because we'll need to align some pictures to the left and right using
float.
Any ideas why the hyperlink prevents text-align to work?

Which platform does not allow multiple FileWriters to open on a file
Which platform does not allow multiple FileWriters to open on a file
JAVA docs for FileWriter say
Whether or not a file is available or may be created depends upon the *

opened for writing by only one* FileWriter (or other file-writing *
object) at a time. In such situations the constructors in this class *
will fail if the file involved is already open."
I need to know what are the platforms which does not allow multiple
FIleWriter on a file.
Thanks

How to check in python if I'm in certain range of times of the day?
How to check in python if I'm in certain range of times of the day?
I want to check in python if the current time is between two endpoints
(say, 8:30 a.m. and 3:00 p.m.), irrespective of the actual date. As in, I
don't care what the full date is; just the hour. When I created datetime
objects using strptime to specify a time, it threw in a dummy date (I
think the year 1900?) which is not what I want. What's the easiest and
most pythonic way to accomplish this?
Extending a bit further, what I'd really like is something that will tell
me if it's between that range of hours, and that it's a weekday. Of course
I can just use 0 <= weekday() <= 4 to hack this, but there might be a
better way.

Python Threading with win32ui DDE module
Python Threading with win32ui DDE module
Running Python2.7 32 bit Windows. It would appear that the dde module (or

This Works:
(I.E. Doesn't fail epically.)

self.tag = tag #string
self.first = first #string
self.second = second #string
self.server = server #dde server object
self.conversation = dde.CreateConversation(server)
#The focus of the problem. Here it works.
self.conversation.ConnectTo(self.first, self.second)
def run(self):
print ""
def main():
machine = "Irrelevant_MachineName"
tag = "Irrelevant_Tagname"
server = dde.CreateServer()
server.Create("Irrelevant_ServerName")
t = Conversation(server, "Irrelevant_Name", machine, tag)
t.start()
main()
This doesn't:

def __init__(self, server, first, second, tag):
self.tag = tag #string
self.first = first #string
self.second = second #string
self.server = server #dde server object
def run(self):
self.conversation = dde.CreateConversation(server)
#Focus of problem.
#Inside here it does not work.
self.conversation.ConnectTo(self.name1, self.name2)
def main():
machine = "Irrelevant_MachineName"
tag = "Irrelevant_Tagname"
server = dde.CreateServer()
server.Create("Irrelevant_ServerName")
t = Conversation(server, "Irrelevant_Name", machine, tag)
t.start()
main()
When it fails, I get this error:

Which corresponds, as one might expect, to Why would this be? This is
going to be my first multithreaded program, so I'm not sure if I'm doing
something stupid here.
But to me it seems perfectly reasonable that I should be able to call the
dde.server.conversation object's ConnectTo method from within the
threading module's "run()" method.
I'd looked into multiprocessing, but I don't think that's as applicable to
my situation.
So, any ideas? I would greatly appreciate the help!!!

The concrete implementation of an Animal class is resolved during runtime.
It's obvious, that removing the virtual keyword from Animal class results
in calling Animal implementation of get() method, whether animal* points
to Bird or Chicken.
What do you want? 1-Animal, 2-Bird, 3-Chicken
3
You chose Chicken
Animal is born
Bird is born
Chicken is born
get() from an Animal!
It's also obvious, that calling the virtual get() method results in
polymorphic call to the concrete subclass. What concerns me is this
situation: Instead of
Animal* animal = factory.generateAnimal();
animal->get();
we have
Bird* bird = factory.generateBird();
bird->get();
We have a pointer to Bird class, in which the get() method is NOT virtual.
The output is:
What do you want? 1-Animal, 2-Bird, 3-Chicken
3
You chose Chicken
Animal is born
Bird is born
Chicken is born
get() from a Chicken!
How does it happen, that call to non-virtual function results in virtual
call to the subclass? Is "virtualism" inherited? If it is, is it somehow
possible to perform a non-virtual call to the pointer class, instead of
implementation class?

Hit OutOfMemoryError when load large blob column from mysql
Hit OutOfMemoryError when load large blob column from mysql
One of my table contains one blob column, and sometimes the size of the
column value would be more than 500M, which is larger than the defalut max
heap size, e.g. -XMX is setting as 512M in my Application Server. In my
code, I have set the fetch size of PreparedSTatement to Integer.MIN_VALUE
to utilize the Mysql Stream support. Also, I add "useServerPrepStmts=true"
into the database url. With these settings, I can insert record with large
column (>500M) successfully, but when I trying to get the record, I always
hit OutOfMemoryError when calling ResultSet.next(). Note: execute query
can pass, checked with the heap size change, execute seems don't load any
real record data. ResultRet rs = Prestatement.execute(...). rs.next();
The mysql driver I'm using is 5.1.17.
Below is the exception stack. It looks like the driver tries to load the
whole column value into memory, which cause OutOfMemoryError here.

Connect to an action in a namespaced controller that isn't a collection or member
Connect to an action in a namespaced controller that isn't a collection or
member
I want to have a url like this:
/admin/providers/connect
that a 3rd party can post to. It isn't a restful resource. Its just a url.
I'd like it to map to the connect method in my providers controller in the
admin namespace.
How can i do that?
here is what i have:
namespace :admin do
get '/admin/providers/connect', to: 'providers#connect'
end
which is just redirecting to the dashboard.

want to add the country you asked about to the dictionary (if it doesn't
already know it). I think the code is just fine. But it doesn't really add
the new country-fact to the dictionary after it asks you :/ Can someone
please identify the problem?

MS Access Row locking/Page Locking issue
MS Access Row locking/Page Locking issue
The database is used by multiple users and each user has their own file. I
have changed all possible settings but seems like "edit lock" is still
locking the whole page and not the edited row. Does anyone know the
possible solution? Also the database is split into front and back end.

PAYID BILL Paid Amount

I need to allocate the Paid amoount on the first table based on the bill.
I know that I can use the cursor with WHILE loop and allocate - is there a
better way to do this?
Result should be

Can the new DriveApp parameters be used to search a specific folder?
Can the new DriveApp parameters be used to search a specific folder?
I am looking for a way to search a specific folder using DriveApp in
Google Apps Script. Here is what I have tried:
var folders = DriveApp.getFolderById('searchedFolderId');
var results = folders.searchFolders( "title contains '"+searchTerm+"'");
while (results.hasNext()) {
var folder = results.next();
// do something with search results here
}
Whenever I try this method, I only get the first folder found returned in
the folder iterator even though there are many other results.
I have also tried:
var results = DriveApp.searchFolders( "'searchedFolderId' in parents and
title contains '"+searchTerm+"'");
Now, whenever I try this method, I sometimes get more than one found
folder returned in the folder iterator. Is there a way to search a
specific folder using the DriveApp API...am I doing something wrong?
Thanks!

how to add grid on top of image which is used as panel in google app script?
how to add grid on top of image which is used as panel in google app script?
I am creating a panel having grid with controls like text box,label etc.
which should appear on image.
For that I have main panel
var mainPanel =
app.createVerticalPanel().setId("mainPanel").setVisible(false);
on this main panel I have added an image
var file =getFileFromFolder(existedFileName);
var fileID = file.getId();
var url = 'http://....;
mainPanel.add(mainImage);
Now on this image I need to add some controls so I have done something
like this...
var requiredGrid = app.createGrid(1,
2).setVisible(false).setId("requiredGrid");
mainPanel.add(requiredGrid);
but this adds requiredGrid below the image panel. Now I want to add this
on image i.e. image should come as a background for the requiredGrid.

I'm a front-end novice and am trying to figure out how to build the
following in my rails app:
https://dl.dropboxusercontent.com/u/10334022/browse.png
Each image is a company model with the attributes title, subtitle, image,
and number of deals. I want the entire area of each separate image to be
clickable and link to the "show" action. Also I need to darken the image a
to make the text more readable. My question is how to make each individual
picture-button.
Currently, I have bootstrap deployed on my app via the following gem in my
Gemfile:
gem 'bootstrap-sass', '2.3.2.0'
I am using carrierwave to store the images and they are accessible in the
views the following way:
<%= image_tag @company.image_url %>
This seems like it will be a long answer, but I really don't know where to
start. Thanks alot!

zooming into particular parts of the screen. i want to be able to create
the effect that the app is automatically zooming across the screen and

confusion on subnet total addresses
confusion on subnet total addresses
I know how to get a first and last usable, broadcast and network addresses
but my question is on total addresses,
for example if I have a address 146.88.57.23/25
would it be ---> 255 - 128 = 127 + 1 = 128
would that equal to 128 of total addresses ?

how to create an options menu at the bottom of the device nexus
I have a problem, I would make an application without actionbar but I
would still put a options menu. On devices that have a physical key, do
not show the problem, but on devices like the galaxy nexus, yes. How can I
make a options menu that appears in the bottom of the screen? To help you
understand I put a picture below.
Thanks in advance for the answers

How to remove word in C string
How to remove word in C string
I currently have a char array that is storing a filename.
eg. folder1/subfolder/subsubfolder/file1.txt
I want to be able to remove the first folder name in this char array. so
it becomes
subfolder/subsubfolder/file1.txt
I know that basename() will make the output file1.txt but I need the
folder structure, just not the first one.
What is the best way to do it? use / as a delineating character?

Memory leak - multiple instance of activity
Memory leak - multiple instance of activity
I've got a couple of activities. The thing is the app is running out of
memory. I tried to gc.clean() in all activities (in onDestroy), null
references, launchMode="singleTop" but without any success.
In MAT i've found out that I have multiple objects of the same activity
and it a default behaviour, if I'm not mistaken.
If i launch at first time, for example i will have main activity: 1, if i
will quit and launch again i will have 2 instance.
that the VM budget just grow and make force close dialog.
Example of my code:
public class Splash extends Activity { private RelativeLayout splash_layout;
private RelativeLayout welcome_message_layout;
private TextView welcome_message_text;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.splash_layout);
splash_layout = (RelativeLayout)findViewById(R.id.splash_layout);
welcome_message_layout =
(RelativeLayout)findViewById(R.id.welcome_message_layout);
welcome_message_text = (TextView)findViewById(R.id.welcome_message_text);
if(ref.getBoolean("LANGUAGEMODECHANGE",false))
{
welcome_message_layout.setBackgroundResource(R.drawable.welcome_message);
welcome_message_text.setText(getString(R.string.welcome));
switch(ref.getInt("LANGUAGEMODENUMBER",Consts.DEFAULT))
{

Embedding Image Data in CSS with System.Web.Optimization
Embedding Image Data in CSS with System.Web.Optimization
I have been searching all day reading articles, blogs, forums about this,
but either I'm not understanding it well or I truly haven't found the
answer.
On my site, I have implemented microsft.web.optimization v.1.0.0 and found
an extension method below (which can be found at Optimizing without
drawbacks):
public class CssImageEmbedTransform : CssMinify {
private static readonly Regex url = new
Regex(@"url\((([^\)]*)\?embed)\)", RegexOptions.IgnoreCase);
private const string format = "url(data:image/{0};base64,{1})";
public override void Process(BundleResponse bundle) {
base.Process(bundle);
string reference = HttpContext.Current.Request.ApplicationPath +
"includes/css/";
// Before Using BundleTable to ResolveUrl in head control
// HttpContext.Current.Request.Path.Replace("/barry.css", "/");
// debug stuff
// HttpContext.Current.Response.Write("<br />Before Matches<br />");
//
HttpContext.Current.Response.Write(url.Matches(bundle.Content).Count
+ "<br />");
foreach (Match match in url.Matches(bundle.Content)) {
var file = new FileInfo(HostingEnvironment.MapPath(reference +
match.Groups[2].Value));
if (file.Exists) {
string dataUri = GetDataUri(file);
bundle.Content = bundle.Content.Replace(match.Value,
dataUri);
HttpContext.Current.Response.AddFileDependency(file.FullName);
}
}
// debug stuff
// HttpContext.Current.Response.Write("After Matches");
// HttpContext.Current.Response.End();
}
private string GetDataUri(FileInfo file) {
byte[] buffer = File.ReadAllBytes(file.FullName);
string ext = file.Extension.Substring(1);
return string.Format(format, ext, Convert.ToBase64String(buffer));
}
}Along with this code:
private void SetupBundles() {
BundleTable.Bundles.EnableDefaultBundles();
Bundle css = new Bundle("~/mycc.css",
typeof(CssImageEmbedTransform));
css.AddFile("~/includes/css/mycss.css");
BundleTable.Bundles.Add(css);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}What that did was convert background-image:
url(Images/myImage.png?embed); to background-image:
url(data:image/png;base64,iVBORw0KGgoA...lFTkSuQmCC);.
I have recently updated my site to use system.web.optimization v.1.1.0
(found at Bundling and Minification) and I'm wondering if there is
something similar or better (maybe built-in) to accomplish the same?
Thanks!

Record last activity of a logged in user in Pyramid
Record last activity of a logged in user in Pyramid
In an application I am building in Pyramid,I have a users table with a
field called 'last_activity'. This field is intented to store the
timestamp of the last time a user visited a page in the system.
Since I'm still a bit new in pyramid, I don't know if pyramid has some
sort of way to create a "common" view that can be executed everytime a
user visits any page in the site (in order to update the 'last_activity'
field in this view function). Is this possible?
If that is not possible, what would you recommend me to do this?
Thanks in advance.

If my alphabet is {a,b} and my nfa has a state q0 with the following

Is this table wrong? should delta(q0, b) = q1 because q0 can move on (no

How to calculate address subtraction in c++
How to calculate address subtraction in c++
I am a little surprised by the output of the following code:
double array[] = {4, 5, 6, 8, 10, 20};
double* p = array + 3;
//Print array address
cout << (unsigned long)(array) << endl; //This prints 1768104
cout << (unsigned long)(p) << endl; //This prints 1768128
//print p - array
cout << (unsigned long)(p - array) << endl; // This prints 3
I am surprised that the last line prints 3. Shouldn't it print 24 = 3 * 8
bytes? Also, as expected, the address of p is the address of array + 3 * 8
bytes. This seems inconsistent. In fact, it is not even a legal assignment
to write: p = p - array; // can't assign an int to type double* No idea,
why this is an int.

Unit tests with java
Unit tests with java
I'm working on test cases in java.
I have a code something like this:
class Sample
{
public boolean isALive(boolean isLive, int num)
{
return if isLive ? num == 3 : num == 2 || num == 3;
}
}
In the tests, it will be something like this,
assertTrue(x.isAlive(true,1); with various combinations
Is there way to simplify or optimize this even more for all the tests to
pass ?

Converting a PHP function to Objective-C and Java?
Converting a PHP function to Objective-C and Java?
I've written a function in PHP that I now need to write in Objective-C and
Java for an iOS and Android app respectively, but having issues with where
to even start.
The function is:
public static function decrypt($string, $key='my_key')
{
$result = '';
$string = str_replace(' ', '+', $string);
$string = base64_decode($string);
$string = str_replace($key, '', $string);
for($i=0; $i<strlen($string); $i++) {
$char = substr($string, $i, 1);
$keychar = substr($key, ($i % strlen($key))-1, 1);
$char = chr(ord($char)-ord($keychar));
$result.=$char;
}
return $result;
}
Result should return string:id
Anyone able to show me how to covert this into both languages? Any
guidance would be greatly appreciated.

CustomListView and CursorAdapter Searching issue
CustomListView and CursorAdapter Searching issue
I have a custom ListView and I can access and show data from database. I
also have serach filter to search data in customListview
/*

*/
cursorAdapter.setFilterQueryProvider(new FilterQueryProvider() {
public Cursor runQuery(CharSequence constraint) {
return dbHelper.fetchDataByName(constraint.toString());
}
});
searchOption.addTextChangedListener(new TextWatcher() {
@Override

int count) {

The problem is When I don't perform any search, onItemClick is working
fine. But, when I try to Search any ListView item and want to access that
item. It shows this

Now, My question why this is happening? How can I solve that ? Can you
give me a tutorial project link similar search function and
customListview, So that I can see what they're doing. I tried to find it
on google,but didn't found. Thanks
I have a custom ListView and I can access and show data from database. I
also have serach filter to search data in customListview
/*
* Serach Filter
*/
cursorAdapter.setFilterQueryProvider(new FilterQueryProvider() {
public Cursor runQuery(CharSequence constraint) {
return dbHelper.fetchDataByName(constraint.toString());
}
});
searchOption.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int start, int before,
int count) {
// TODO Auto-generated method stub
AbstractActivity.this.cursorAdapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence s, int start, int
count, int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
The problem is When I don't perform any search, onItemClick is working
fine. But, when I try to Search any ListView item and want to access that
item. It shows this

casperjs page loading: how to auto-load page's script files?
casperjs page loading: how to auto-load page's script files?
I'm new to casperjs and my desire is to try to test the javascript loaded
by certain pages of a web app. I'm using casper.thenOpen to load a page
from the web server, but it doesn't in turn load the tags that reference
js files. I even checked the web server's access log and sure enough, only
the page itself was requested, not the js files.
I would imagine there is built in functionality for doing this, but if I
have to do this manually I can live with writing my own utility function
for it. But again, being new to casperjs, I'm not sure how I'd go about it
- I haven't been able to locate examples that will help me figure this
out.

This is my HTML code
<div id="menu_status_item">
<span class="menu_status_bar"></span>
</div>
This is my CSS:
#menu_status_item
{
margin-top: 40px;
width: 100%;
}
.menu_status_bar
{
margin-left: 45px;
color: #fff;
}
And this is my jquery
var statusMessage = 'Success'
var colorCode = '';
var statusText = '';
if(statusMessage.indexOf("Success") > -1) {
colorCode = '#33CC33';
statusText = 'Success';
}else{
colorCode = '#CC0000';
statusText = 'Failure';
}
$(".menu_status_bar").css("display", "inline-table");
$(".menu_status_bar").text(statusText);
$("#menu_status_item").animate({backgroundColor: colorCode}, 4000);
$("#menu_status_item").animate({backgroundColor: "#ffffff"});
$(".menu_status_bar").css("display", "none");
Basically i want the text "Success" inside the menu_status_bar to appear,
do the animation, and disappear with the display: none.
If i use the display:none at the end, the text won't even show up. If i
remove it, the animation works, but the text will remain there... if
someone selects it, its horrible because the text will be highlighted.
Does any one know what could this be? or how can i achieve the same result
but doing it differently?
Thanks.

Is a static variable in java treated as a pointer internally?
Is a static variable in java treated as a pointer internally?
I have a question about the key word static. Lets say for instance we have
this piece of code.
public class Foo
{
private int age;
private static int weight;
..
...
}
Say in main you create 2 objects. You change the age in one and then you
change the weight in the other. Does that mean that the weight also
changes in the first object as well? If that is the case then does that
mean that weight is a pointer?
I guess my question in a nutshell would be. How does static work
internally? Is it essentially of a pointer type?

Using Regex to validate a variable length string
Using Regex to validate a variable length string
I'm trying to validate a form field in Java using Regex, which can have 5
different format possibilities. I'm struggling to get this one working.
The string to be checked will be between 4-6 alphanumeric characters.
If it's 4 characters, it must be all numbers.
^\\d{4}$
If it's 5 characters, it can be all numbers, first position letter with 4
following numbers, or first 3 positions letters followed with 2 numbers.
^\\d{5}$
^[a-zA-Z]\\d{4}$
^[a-zA-Z]{3}\\d{2}$
And if it's 6 characters, it will be first position letter, 4 numbers, and
last another letter.
^[a-zA-Z]\\d{4}[a-zA-Z]$
I just can't seem to piece it all together though.

Based on multiple criterias on parent's siblings
Based on multiple criterias on parent's siblings
I would like to know if I can combine at the same time an XPath looking
for the previous sibling of a certain class with a certain text and at the
same time a sibling at the same level with a certain text.
For example I would like to find the following cells:
<td class="sdawatt_booknow"><a href="#"
onclick="wa_class_book(160832)">Book</a></td>
by looking up a sibling of class sdawatt_hrdcell containing the text Spin
preceded by a td of class sdawatt_banner with the text Monday - 16
September 2013.
Or the following td:
<td class="sdawatt_booknow"><a href="#"
onclick="wa_class_book(160864)">Book</a></td>
if we look for the date of the 'Friday - 13 September 2013'.
Is this something doable in Xpath ?

by looking up a sibling of class sdawatt_hrdcell containing the text Spin
preceded by a td of class sdawatt_banner with the text Monday - 16
September 2013.
Or the following td:
<td class="sdawatt_booknow"><a href="#"
onclick="wa_class_book(160864)">Book</a></td>
if we look for the date of the 'Friday - 13 September 2013'.
Is this something doable in Xpath ?

How do I add the distances in a while loop?
How do I add the distances in a while loop?
I am supposed to add the distance of a walker's position after N steps. I
run the while T times and need to add all of the N steps after T trails
and divide by the amount of trials to get an average. This is my code so
far. Iv tried doing a different integer like distance/T but it says that
distance isn't found. Is that because it is defined in the while loop. I
am using processing.
import javax.swing.JOptionPane;
String input=JOptionPane.showInputDialog("Steps");
int x=Integer.parseInt(input);
if (x<0)

Directly from this API:
NumberFormat helps you to format and parse numbers for any locale. Your
code can be completely independent of the locale conventions for decimal
points, thousands-separators, or even the particular decimal digits used,
or whether the number format is even decimal.

Calculating a future date
Calculating a future date
I have created a program to calculate days and in my program i want add 7
more days to the current date.
Which means if today's date is 9/11/2013, i want to make it 9/18/2013 by
getting the current date and adding 7 more days to it. How do i implement
this.
I know how to get today's date by using the date class but i don't know to
add another 7 days to the current date.
This is the method i used to get the current date :
public void dateCalculator(){
Date date;
date=new Date();
}
Thank you for your time.

Misunderstanding of Python imports
Misunderstanding of Python imports
I am having a recurring problem in the way I program and I need help
restructuring the way I do things.
Warning: This is a long question. I want to include as much information
about the nature of the error as possible to exhaust possible causes of
it.
TL;DR Version: import/include order isn't letting my main file see
functions defined in other files. How can I improve my programming style
to prevent this later?
Long version: I'll use Python 2.7 as an example. Let's say I have a file,
main.py, and another file, foo.py. main.py has all my main code, and
foo.py has a class that contains data used in main.py. What I do is I
define the class's object in that same file, foo.py, right after the class
definition. I figure if I just instantiate the class there, I can simply
import that file into any other files that need it, and the object will
already exist to be used immediately. No mucking about with instantiating
the class at some point and worrying whether or not something before the
class's instantiation needs it before it's actually defined.
The problem is that this normally works, until I do that with another
class defined in another file. The interpreter can't find the object of
the second class, even if I import it once in main.py (therefore this does
not seem to be an issue of duplicate objects stemming from multiple
imports). So, in essence, main.py can see foo.py's class object, but not,
say, bar.py's object.
I normally set up a project so that I have one main file, and other files
that define data and the uses and handling for that data. The main file
calls one function or method that gets the ball rolling by calling other
functions and methods throughout the program. I import just the data for
the class whose method I'm calling, and in the file that has the data used
in the main file, I import all the other stuff that particular file needs.
This seems logical to me if I'm to make a memory-efficient program, but
there is obviously something wrong with the way I'm doing things, because
it never seems to work with bigger programs.
Here is a simple example in code of (a. how I set up my file hierarchies,
(b. how I set up my imports, and (c. an example of the types of errors I
get:
main.py:
import foo
import bar
print foo.bar
print bat.bar
foo.py:
class Foo:
def __init__(self):
bar = 5
foo = Foo()
bar.py:
class Bar:
def __init__(self):
bar = "Hello"
bat = Bar()
And here's the error I get when I run this program:
Traceback (most recent call last):
File "C:\Users\User\Desktop\main.py", line 4, in <module>
print foo.bar
AttributeError: 'module' object has no attribute 'bar'
When I change main.py to this:
from foo import *
from bar import *
print foo.bar
print bat.bar
it gets a different error:
Traceback (most recent call last):
File "C:\Users\User\Desktop\main.py", line 4, in <module>
print foo.bar
AttributeError: Foo instance has no attribute 'bar'
Am I misunderstanding how to use imports or what? Because if I step back
and make main.py like this:
from foo import *
from bar import *
foo = Foo()
bat = Bar()
print foo.bar
print bat.bar
while commenting out the instantiation of the classes in the other files,
I get the same error: Foo instance has no attribute 'bar'.
Why is this?
This doesn't just happen with Python, it happens to me with C++ too, so
this is why I suggest it may be my programming style that is an issue here
and not so much anything syntactical.

jerky motion using CMMotionManager iPhone
jerky motion using CMMotionManager iPhone
I am using CMMotionManager to move buttons, images etc. on my view as the
device is tipped forward, backward, right, left. I get the attitude pitch
and roll and then use these to assign values to a string representing
pixel placement on the screen.
Here is how I get the info
motionManager = [[CMMotionManager alloc] init];
motionManager.deviceMotionUpdateInterval = 0.05f;
[motionManager
startDeviceMotionUpdatesToQueue:[NSOperationQueue
currentQueue] withHandler:^(CMDeviceMotion *motion,
NSError *error) {
NSNumberFormatter *formatter = [[NSNumberFormatter
alloc] init];
[formatter
setNumberStyle:NSNumberFormatterDecimalStyle];
[formatter setMaximumFractionDigits:2];
[formatter setRoundingMode: NSNumberFormatterRoundUp];
numberString = [formatter
stringFromNumber:[NSNumber
numberWithFloat:motion.attitude.roll /8]];
numberString1 = [formatter
stringFromNumber:[NSNumber
numberWithFloat:motion.attitude.pitch /8]];
}];
and this is how I assign them.
NSString *deltax = numberString;
NSString *deltay = numberString1;
NSLog(@"xString;%@",numberString);
if ([deltax isEqualToString:@"-0.01"]) {
xString = @"160";}
else if ([deltax isEqualToString:@"-0.02"]) {
xString = @"161";}
else if ([deltax isEqualToString:@"-0.03"]) {
xString = @"162";}
else if ([deltax isEqualToString:@"-0.04"]) {
xString = @"163";}
etc.
I have made them so the x axis continuously goes up and down (back and
forth) on the screen. i.e. -.01 is the same as -.40, .01 and .40. and they
are approached the same as you go up from -.01 and .01the values get
bigger and from -.40 and 4.4 they get smaller. I did the same with y axis
also. -.01 and .01 are 284 and -.20 and .20 are at 264. However in this
case the numbers go up from -.01 and down from .01.
here are some examples
//x axis
if ([deltax isEqualToString:@"-0.01"]) {
xString = @"160";}
else if ([deltax isEqualToString:@"-0.02"]) {
xString = @"161";}
else if ([deltax isEqualToString:@"-0.03"]) {
xString = @"162";}
else if ([deltax isEqualToString:@"-0.04"]) {
xString = @"163";}

In this way there is continuous flow from one orientation to the next.
However I am having a small problem. when the phone is tipped forward and
passes from .2 faceUp orientation to .2 faceDown orientation. I get a
jerky motion. In faceUp .2 buttons etc. move to the left all of a sudden
and when it moves to faceDown .20 they move to the right. Otherwise the
buttons etc. are centered at .19 and -.19 and return there to operate
normally (as expected). I have tried to call DeviceOrientationFaceUp and
FaceDown but this didn't seem to help.
Does anyone have any experience with this behavior and know of a fix or
have any suggestions.
I am using CMMotionManager to move buttons, images etc. on my view as the
device is tipped forward, backward, right, left. I get the attitude pitch
and roll and then use these to assign values to a string representing
pixel placement on the screen.
Here is how I get the info
motionManager = [[CMMotionManager alloc] init];
motionManager.deviceMotionUpdateInterval = 0.05f;
[motionManager
startDeviceMotionUpdatesToQueue:[NSOperationQueue
currentQueue] withHandler:^(CMDeviceMotion *motion,
NSError *error) {
NSNumberFormatter *formatter = [[NSNumberFormatter
alloc] init];
[formatter
setNumberStyle:NSNumberFormatterDecimalStyle];
[formatter setMaximumFractionDigits:2];
[formatter setRoundingMode: NSNumberFormatterRoundUp];
numberString = [formatter
stringFromNumber:[NSNumber
numberWithFloat:motion.attitude.roll /8]];
numberString1 = [formatter
stringFromNumber:[NSNumber
numberWithFloat:motion.attitude.pitch /8]];
}];
and this is how I assign them.
NSString *deltax = numberString;
NSString *deltay = numberString1;
NSLog(@"xString;%@",numberString);
if ([deltax isEqualToString:@"-0.01"]) {
xString = @"160";}
else if ([deltax isEqualToString:@"-0.02"]) {
xString = @"161";}
else if ([deltax isEqualToString:@"-0.03"]) {
xString = @"162";}
else if ([deltax isEqualToString:@"-0.04"]) {
xString = @"163";}
etc.
I have made them so the x axis continuously goes up and down (back and
forth) on the screen. i.e. -.01 is the same as -.40, .01 and .40. and they
are approached the same as you go up from -.01 and .01the values get
bigger and from -.40 and 4.4 they get smaller. I did the same with y axis
also. -.01 and .01 are 284 and -.20 and .20 are at 264. However in this
case the numbers go up from -.01 and down from .01.
here are some examples
//x axis
