Mention 2 modifications that can be done to a linked list data structure
so that it is converted into a binary tree data structure?
It's an A level question. I looked it out on google but only programs are
found. I need theory explanation.

Recursive realtion solution in terms of variable(p) in Mathematica
Recursive realtion solution in terms of variable(p) in Mathematica
u[0, 0] =1 u[m, n] =(1/(p + m + m^2)) (m*u[(m - 1), n] + n*u[(m + 1), (n -
2)] + m*(m - 1)*u[(m - 2), (n + 2)])
I want u[m,n] in terms of p; don't want answer like u[0,2]=2u[1,0]/p only
in terms of p; like I want value of u[m,n] for different value of m and n.

How to rename a column of a pandas.core.series.TimeSeries object?
How to rename a column of a pandas.core.series.TimeSeries object?
Substracting the 'Settle' column of a pandas.core.frame.DataFrame from the
'Settle' column of another pandas.core.frame.DataFrame resulted in a
pandas.core.series.TimeSeries object (the 'subs' object).
Now, when I plot subs and add a legend, it reads 'Settle'.
How can I change the name of a column of a pandas.core.series.TimeSeries
object?
thank you.

Java: Keep SecureRandom (SHA1PRNG) seed secret - calculate hash before seeding?
Java: Keep SecureRandom (SHA1PRNG) seed secret - calculate hash before
seeding?
I'm using SecureRandom with SHA1PRNG to generate a random sequence. I
won't let SecureRandom seed itself, I'm using my own values to seed it.
(Please don't tell me that this is unsafe, I have my reasons for doing
this).
However, I don't want anyone to know what seed I used. The seed must
remain secret and it shouldn't be possible to recalculate the seed from
the random sequence.
Does it make sense to calculate the SHA-512 from my value and seed
SecureRandom with it? Or will SecureRandom create a SHA1 hash from the
seed itself?
Long story short: Should I seed SecureRandom with "value".getBytes() or
with the SHA-512 hash of "value", if I want to keep "value" secret?
Where can I find information how the SHA1PRNG algorithm works?

Why i have null? I not redirect page, my bean is a request, why filed is
null?
I set in the method:
public List<Visit> getVisitFound() {
System.out.println("start" + start);
System.out.println("end" + end);
System.out.println("name" + user.getSpecializationId().getName());
myId = (Integer) session.getAttribute("myId");
return visitDao.visitSearch(start, end,
user.getSpecializationId().getName(), myId);
}
and I see, when i go the page search result. This method is invoked twice.
Why?
And when I run visitPatientMB2.visitRegister() in page searchResult method
starts the third time... This time fields have null. Example:
INFO: startSun Sep 01 00:00:00 CEST 2013
INFO: endSun Sep 29 00:00:00 CEST 2013
INFO: nameKardiolog
INFO: startSun Sep 01 00:00:00 CEST 2013

Why i have null? I not redirect page, my bean is a request, why filed is
null?
I set in the method:
public List<Visit> getVisitFound() {
System.out.println("start" + start);
System.out.println("end" + end);
System.out.println("name" + user.getSpecializationId().getName());
myId = (Integer) session.getAttribute("myId");
return visitDao.visitSearch(start, end,
user.getSpecializationId().getName(), myId);
}
and I see, when i go the page search result. This method is invoked twice.
Why?
And when I run visitPatientMB2.visitRegister() in page searchResult method
starts the third time... This time fields have null. Example:
INFO: startSun Sep 01 00:00:00 CEST 2013
INFO: endSun Sep 29 00:00:00 CEST 2013
INFO: nameKardiolog

is there something wrong with compiler or the regular expression.

Haskell sqrt type error
Haskell sqrt type error
OK, so I'm attempting to write a Haskell function which efficiently
detects all the factors of a given Int, n. Based off of the solution given
in this question, I've got the following:
-- returns a list of the factors of n
factors :: Int -> [Int]
factors n = sort . nub $ fs where
fs = foldr (++) [] [[m,n `div` m] | m <-
[1..lim+1], n `mod` m == 0]
lim = sqrt . fromIntegral $ n
Sadly, GHCi informs me that there is No instance for (Floating Int) in the
line containing lim = etc. etc.
I've read this answer, and the proposed solution works when typed into
GHCi directly - it allows me to call sqrt on an Int. However, when what
appears to be exactly the same code is placed in my function, it ceases to
work.
I'm relatively new to Haskell, so I'd greatly appreciate the help!

Simple string encryption in php and decryption in Java?
Simple string encryption in php and decryption in Java?
I need to transfer some json data from a php server endpoint to my Android
client, however I want to protect obvious reading of the data if the
endpoint gets exposed. So I plan to write some simple string encryption
function in the php endpoint and have my client decrypt it. Is there any
readily made library to do so?

Why use setTimeout in deferred
Why use setTimeout in deferred
I tried to understand of how deferred works,so in all of them they use
setTimeout.
this.callbacks;// array of functions reference
this.callbacks.forEach(function(callback){
window.setTimeout(function(){
callback(data);
},0);
});
one example from this questions that use setTimeout
resolve: function (data) {
this.promise.okCallbacks.forEach(function(callback) {
window.setTimeout(function () {
callback(data)
}, 0);
});
},
What is the different between calling functions in loop by setTimeout than
callback(); or callback.call();

Testing an online shop: buster vs. selenium
Testing an online shop: buster vs. selenium
I'm new to test driven development.
My project is an online shop with legacy Java backend and a static grid
based UI implemented with JSP and a light touch of Javascript/JQuery. We
have two different versions of the UI: one for mobile and one for desktop
browsers.
My task is to choose a test framework and I am thinking to choose between
BusterJS and Selenium. I've been reading a little about both and this is
what I understood:
Selenium is older and has a bigger community plus an IDE that runs on
Firefox and allows rapid test prototyping. It allows running tests in
parallel and supports several programming languages.
Buster.JS is in beta with big promises for the future. We need to write
tests in Javascript.
That's pretty much what I know about them.
We want to test the functionality of our online shop so it doesn't break
between releases (both back-end and front-end). What test frame work do
you recommend and why?

Why this select query to Oracle database doesn't work?
Why this select query to Oracle database doesn't work?
First I tested simple cases:
cmd.Parameters.Add(new OracleParameter(":paramCode",
OracleDbType.NVarchar2)).Value = userCode;
cmd.CommandText = "SELECT * FROM VIEWUSERDATA WHERE Codigo = :paramCode";
cmd.CommandType = System.Data.CommandType.Text;
OracleDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
//Works, retrieve data
}
Another:
cmd.Parameters.Add(new OracleParameter(":paramRole",
OracleDbType.NVarchar2)).Value = userRole;
cmd.CommandText = "SELECT * FROM VIEWUSERDATA WHERE Role = :paramRole";
...
while (reader.Read())
{
//Also works
}
But when join, doesn't work.
cmd.Parameters.Add(new OracleParameter(":paramCode",
OracleDbType.NVarchar2)).Value = userCode;
cmd.Parameters.Add(new OracleParameter(":paramRole",
OracleDbType.NVarchar2)).Value = userRole;
cmd.CommandText = "SELECT * FROM VIEWUSERDATA WHERE Role = :paramRole AND
Code = :paramCode";
...
while (reader.Read())//don't retrieve anything
{
}
Data exists, If I do the query in an external query editor(window) works
fine.
Thanks.

How to "convert" processor/chipset name to /proc/cpuinfo output?
How to "convert" processor/chipset name to /proc/cpuinfo output?
I'm trying to choose a laptop and see "Chipset" and "CPU" being listed as
a codename.
Sometimes there is an article in Wikipedia about the processor or chipset
mentioning it's features, sometimes not.
How to know in advance what "cat /proc/cpuinfo" will output (i.e. what
features the processor will exactly support) without actually buying the
device?
For example, how to know in advance if hardware is capable for video
adapter pass-thought into KVM virtual machine?

Fresh install of Windows keeps freezing
Fresh install of Windows keeps freezing
I got a computer from a friend who said he got some viruses and that he
didn't have the time to fix it. I decided to just reformat and do a fresh
install. Windows 7 installed fine but after booting in, it would freeze
every twenty minutes or so and I would have to reboot.
I thought maybe I messed up installing something so I reinstalled it.
Still froze. I put in a Debian LiveCD I had lying around and that worked
fine. Booted back into Win7, but safe mode this time, and that worked fine
as well.
Any ideas?

Kendo UI Sparkline - Datasource/Series/Categories
Kendo UI Sparkline - Datasource/Series/Categories
I have a Kendo UI Sparkline now that I am populating from my model with
the following:
@(Html.Kendo().Sparkline()
.Name("jph-graph")
.Theme("black")
.Type(SparklineType.Column)
.Tooltip(tooltip => tooltip.Format("{0:n2}"))
.Data(Model.jphList.Select(g => g.value).ToList())
)
The Sparkline populates properly with that.
I want to add a category so that I can include that value in my ToolTip.
All I could find were references to using the category, so I started
trying to use .DataSource so I could implement that. Now I can't even get
the Sparkline to populate with the defined Datasource and Series, much
less get the Category working. Here is the code that I have that does NOT
populate the Sparkline.
@(Html.Kendo().Sparkline()
.Name("jph-graph")
.Theme("black")
.Type(SparklineType.Column)
.Tooltip(tooltip => tooltip.Format("{0:n2}"))
.DataSource(ds => Model.jphList.Select(g => new { date =
g.production_date, value = g.value }).ToList())
.Series(series => series.Column("value"))
)
Any help would be appreciated.

Finding comments in a string
Finding comments in a string
I have file which has comments at the top.
e.g.
/**
* Comments for file.
*
*/
Using PHP, I read content of file using file_get_contents into variable
now I want to get value present inside comment. For above example expected
result would be
* Comments for file
*
*
Which means I want content inside those /** and */. This file can have
multiple comments but I want the very first which is at the top of file.
Any ideas/help please ?

Windows 7 keyboard input hangs while reading from usb hard drive
Windows 7 keyboard input hangs while reading from usb hard drive
There is a strange behavior of windows 7. I like to listen to music while
coding (surprising), so I always carry with me my usb storage and play
music from it. Sometimes while playing a song it kind of "hangs" (guess
loads the buffer). What is strange that my mouse keeps working, but any
input that I type is not appearing until it "releases". Why does it
happens? Why it doesn't receive IO from keyboard but does receive mouse?
Why does the system hang at all, shouldn't interrupts handle this?

How to select random subset of cases in SPSS based on student number?
How to select random subset of cases in SPSS based on student number?
I am setting some student assignments where most students will be using
SPSS. In order to encourage students to do their own work, I want students
to have a partially unique dataset. Thus, I'd like to get each to the open
the master data file, and then get the student to run a couple of lines of
syntax that produces a unique data file. In pseudo code, I'd like to do
something like the following where 12345551234 is a student number:
set random number generator = 12345551234
select 90% random subset ofcases and drop the rest.
What is simple SPSS syntax dropping a subset of cases from the data file?

Java Program that accepts input and meanwhile runs a timer
Java Program that accepts input and meanwhile runs a timer
I want to make a small java program that does the following: When it
starts running, a timer of 00:00 starts as well at the same time. Then,
the program asks the user for a user input (only "*" can be given) and
when it's inserted, it prints the very next number that has 0 in its last
digit of the timer. Example: program runs, timer as well, user gives *,
meanwhile, before it is inserted (by enter), timer continues to run and
when it is inserted, the timer is at 00:35 for example, and at 00:40 it
prints 00:40. Continues to run.. is at 01:32, gets insert, prints 01:40 at
that time, etc. Kinda confusing huh? :)
I don't know how to accomplish this, what should I read? Thanks a lot

Store hash password and encrypted data with this password in db? [migrated]
Store hash password and encrypted data with this password in db? [migrated]
I'm currently developping a django application.
I need to store user data. This data must be unavailable to any other user
or admin
I've created a dedicated user account system (no using dj auth). (Maybe I
could modified it, but this is not the subject here..)
User password is hashed with passlib.
User data is encrypted using AES and user password (not hashed :p) as
secret key.
I'm wondering :
Is it safe to keep hashed password and encrypted data, when encryption
used this password as secret key ?
What can I do with AES IV used to crypt user data ? Generate it when I
create the user and keep it in user table, next to hashed password ?

Invalid URI error with MongoDB connection string but only when run on Azure? (ASP.NET Web Role)
Invalid URI error with MongoDB connection string but only when run on
Azure? (ASP.NET Web Role)
I have an ASP.NET MVC Web Role that communicates with a remote server
running MongoDB. The connection string has the credentials in it. When I
run the the MVC Web Role on localhost it works fine. However, when I
publish the MVC Web Role to Azure and run it I get the following
error/stack trace:
Invalid URI: There is an invalid sequence in the string.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.
Exception Details: System.UriFormatException:
Invalid URI: There is an invalid sequence in the string.
Source Error:
An unhandled exception was generated during the execution of the current
web request.
Information regarding the origin and location of the exception can be
identified using

Why would the UnescapeString() method or this stack of calls behave
differently if the code is running on my local PC versus on Azure?

Continuing a "stopped" iCloud restore on iOS
Continuing a "stopped" iCloud restore on iOS
I was restoring my iPhone 5 to the latest iOS and chose restore via
iCloud. The restore process - especially for apps - was frustratingly slow
and actually stopped frozen after a while.
After trying several other options, I finally "Cancelled" the iCloud
Restore operation and then manually installed the apps via iTunes, as well
as synced songs, etc.
Now for some of the apps, data is missing and my Photos also appear to be
incomplete. Since I "cancelled" the iCloud Restore (and was warned about
not being able to do this again), is there any way at all I can coax
iCloud into streaming the app data back into the installed app folders, as
well as getting my photos? Would there perhaps be two separate ways of
doing that?
Or is the only other option to "Erase Content and Settings" and do the
restore process all over again, allowing Photos to restore gradually via
iCloud, while installing apps via iTunes parallely (without "Cancelling"
the iCloud restore)?
If the answer to the last question is "Sadly, yes", then can it be assumed
that if the app is installed via iTunes anyway, iOS will proceed to
restore the app's data from iCloud? Or does the app HAVE to be installed
OTA for the data to also be restored from iCloud?
Thanks.

Haskell tuple function composition
Haskell tuple function composition
I have started learning Haskell from Introduction to FP using Haskell by
Richard Bird, but I am stuck in proving the following:
pair (f, g) . h = pair (f . h, g . h)
The definitions of pair is the following:
pair :: (a -> b, a -> c) -> a -> (b, c)
pair (f, g) x = (f x, g x)
Could someone point me in the right direction? Please keep in mind that I
am only at the beginning. Thanks in advance!

Autocomplete div under textfield
Autocomplete div under textfield
In my site I have a text field that has to function as a autocomplete box.
I use this code:
<input type="text" class="input2" style="margin-bottom:0px;"
id="customersearchfield">
<div id="customersearchresult" style="display:none; position:absolute;
z-index:999; background:#fff; color:black; ">
CSS:
.input2{
display: inline;
margin-top: 4px;
padding: 3px;
border: 0px;
width: 200px;
}
This does not work as expected. The resultdiv is placed directly under the
textfield vertically, but not aligned horizontally. It just aligns to the
left side of the browser window.
How to get the top left corner of the resultdiv directly under the bottom
left corner of the text field so that it appears directly under the
textfield?

eclipse isn't working after reinstalling jre and jdk
eclipse isn't working after reinstalling jre and jdk
I used eclipse for android development. today I reinstalled the jre and
jdk for a wrong reason, after that my eclipse doesn't work and says: A
java runtime environment (jre) or java development kit (jdk) is needed in
order to run eclipse... but i know that they are installed on my computer
and when i use a new eclipse it doesn't have any problems for starting but
when i changed the workspace to one which i used with my ex-eclipse, a lot
of the codes were underlined red showing they have errors. it seems that
the current sdk is not same with the older eclipse. this version is older.
what should i do? is there any way to bring my ex-eclipse working again?

I have a problem with renaming pictures in my gallery, here I have a

PERFECTLY but when I decide to rename it again
It works by this way

I can't find a way to keep ONLY the ID and add a text, and I don't wanna

It shows only 465 mb free memory out of 12GB. Now I tried to find what

Does any one know how to find where my memory is consumed or which

Whether I have done it in right way. How can i reduce the memory

Whether I have done it in right way. How can i reduce the memory
consumption so that my website doesn't go down. Is there need to increase
RAM.

Getting Context from other class causing NPE
Getting Context from other class causing NPE
I'm trying to call a new activity in non-activity class using this codes:
Intent usage = new Intent(UsageActivity.getContext(),UsageActivity.class);
usage.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
UsageActivity.getContext().startActivity(usage);
and I have a UsageActivity that has this codes:
public static Context mContext;
below the onCreate()
mContext = getBaseContext();
i created a method like this:
public static Context getContext() {
return mContext;
}
It throws an exception saying this:
04-25 17:30:00.485: W/System.err(6518): java.lang.NullPointerException

Does my way of creating a context was wrong? any thoghts will be highly
appreciated.

Deleting a pointer to global variable?
Deleting a pointer to global variable?
So, i have two global variables, that i want to point to object of a
certain class. I have them declared in one .h file as
extern Obj* pointer.
I inicialize that variable inside my main function, as follows:
pointer = new Obj();
later on, i call some functions inside main etc. Can i call delete
operator at the end of main, like so:
delete pointer;
My main, in general would look like:
int main(){
pointer = new Obj();
...
delete pointer;
}

How to align two sets of timestamps
How to align two sets of timestamps
This was a tricky question to name. Here is what I am trying to do: I have
two sets of timestamps. I name the first one t_x and the second one t_y.
For one t_x there are several corresponding t_y's.
For example, take t_x = [1,4,6] and we have t_y[1] = [1,3,7], t_y[4] =
[2,4,6] and t_y[6] = [5,6,7].
This could be plotted in a (t_x, t_y) graph. Now I am taking the set of
slopes, which is (t_y1 - t_y2)/(t_x1 - t_x2), for t_x1 "close" to t_x2 and
t_y1 "close" to t_y2.
The question here is the following: what would be the most time-efficient
way to process the slopes? Is there a good data structure to hold the
timestamps in order to speed up the calculation?
I am using mostly python by the way, but I can read most common languages.

What is scope in Javascript?
What is scope in Javascript?
I don't understand what the scope is. I've read somewhere that scope is
the way to access varible. But I find it hard to come up with a case when
a variable is accesible through scope. All varibles inside a function can
be accessed through context of either 'global' or 'activation/variable'
object or through closure. Here is the piece of code to demonstrate what I
mean:
var global_var = 7;
var f = (function() {
var closure_var = 5;
return function() {
var local_var = 3;
alert(local_var); // alerts 3 - visible through context as
Activation Object's property
alert(closure_var); // alerts 5 - visible through closure
alert(global_var); // alerts 7 - visible through context as
Global Object's property
alert(this.global_var); // alerts 7 - visible through context as
Global Object's property
}
})();
f();
So what is scope? Here is the extract from here and my comments:
// a globally-scoped variable
var a=1;
// global scope
function one(){
alert(a);
}
// no, it's accessible as global object's context
// local scope
function two(a){
alert(a);
}
// no, it's accessible as activation object's context

Grid scrollbar below grid
Grid scrollbar below grid
I use DevExpress and I have a GridView.Data for the grid is generated
dynamically.I want to set scrollbars if there is not enough space on the
screen,but I don't know how.I have tried to set overflow:auto,but then I
have to set height,which is different every time.I could use CSS3 calc()
function but it is not supported on Android.If i set height to 100% the
scrollbar goes below grid and last few rows can't be seen.Do you have any
suggestions?I don't want to use Javascript.

R Studio does not install pacjages
R Studio does not install pacjages
I have a problem when I am trying to install r-packages in my Windows 7. I
have R Studio 2.15.3
When I try to install a new package a window pops-up asking me if I want
to create a new folder to save the package as there isn't one. But when I
click yes, nothing happens. When I try to type the command in the R
console then I came up with this:
Warning in install.packages : cannot create dir 'C:\Users\ΠαÏις',
reason 'Permission denied' Error in install.packages : unable to create
'C:/Users/ΠαÏις/Documents/R/win-library/2.15'
Does anyone knows where the problem lie?

Is it possible that "ensconce," "sconce," and "abscond" could be cognates?
Is it possible that "ensconce," "sconce," and "abscond" could be cognates?
It seems impossible that "sconce" and "ensconce" are not cognate. However,
according to The Etymological Dictionary:
sconce (n.) Look up sconce at Dictionary.com late 14c., "candlestick with
a screen," a shortening of Old French esconse "lantern, hiding place,"
from Medieval Latin sconsa, from Latin absconsa, fem. past participle of
abscondere "to hide" (see abscond). Meaning "metal bracket-candlestick
fastened to a wall" is recorded from mid-15c. ensconce (v.) Look up
ensconce at Dictionary.com 1580s, "to cover with a fort," from en- (1)
"make, put in" + sconce "small fortification, shelter," perhaps via
French, probably from Dutch schans "earthwork" (cf. Middle High German
schanze "bundle of sticks"), of uncertain origin. Related: Ensconced.

Nivo Slider Fails to Show 3rd Image in Chrome
Nivo Slider Fails to Show 3rd Image in Chrome
The page in question can be viewed here:
http://quiltersrule.com/beta/index.html and of course just use chrome to
view the code.
I noticed that 80% of the time, my 3rd slider image just plain doesn't
show. The slider just collapses until it moves onto my placeholder image
#4. I have no idea what is going on. The image is the same size as the
others, and I don't suspect a loading-time issue.
This only seems to happen in Chrome. I have not tried FF, and it does not
happen in IE.

synchronizing workers Algorithm
synchronizing workers Algorithm
I have a scenario, where i am monitoring a dozen of stocks.
Worker
worker (a method) takes a stock (assigned by manager), Monitors it for 5
consecutive negative Units. Each unit is say 0.5% of a stock price. Eg:
for a stock, costing 100$. Each unit is 50C.
If its price falls to 99.4$ => One unit down. (Intermediate fluctuations
in a unit are OK.)
If its price falls to 98.8$ => Two units down from 100$
If its price falls to 98.4$ => Three units down from 100$
IF a stock price goes down by 5 units, the worker reports to manager. End
method here. iF a stock price moves up by 2 units, report to manager and
end method here.
Manager
Assigns a worker for each of these dozen stocks. (Calling the same method.
Thread: Non Blocking) Wait till all of them terminate. check if all of the
stocks are moving up/down.
If all are moving up, Call "Handle_Rising Market" method
If all are moving down, Call "Handle_Crashing_Market" method
If some are moving up, and some moving down, Call worker again for each of
them, Manager must end only when all report either UP or DOWN. till then
the check must go on.
I am looking for the fastest algorithm. This is a traditional Worker
manager problem, with extra scenarios. The repeated check to ensure that
all of them are moving up/down is where i am stuck! Any advice is highly
appreciated.

shouldn't really matter), I have an external HD enclosure that I use for
media and other stuff that doesn't need to be extra-speedy. It's my
in-case-of-a-flood-grab-this-thing-and-go enclosure, so it has data on it
that I work with throughout the day. The enclosure (like most) has
separate power switch. When the OS turns tells it to go to sleep, it needs
to be physically turned back on. So when Windows tells it to go to sleep,
nothing can access the drives until I push the button.
Anyway.
With Win7 and Win8, some simple adjustments to the power settings to turn
"USB selective suspend setting" off stopped the enclosure and its drives
from going to sleep.
With 8.1, this isn't the case. I believe I've hit all of the obvious power
settings, so looking for something I've missed.
Power settings: USB selective suspend: DISABLED Turn off hard disk after:
NEVER Device manager | all USB Root Hubs | Power Management | Allow My
Computer to Turn Off This Device: DISABLED
I can hack my way around this with an every-10-minute script that writes
and deletes a file to one of the drives, but I'd rather have an answer to
Win 8.1's change to USB power management.

How to kill mousemove after click in this jquery function?
How to kill mousemove after click in this jquery function?
This is a button that follows mouse movement. I would like to stop this
button when mouse is clicked on it!
jQuery( document ).ready( function() {
$( "#enbfb-button-wrapper-5" ).parent().mousemove( function( e ) {
jQuery( "#enbfb-button-wrapper-5" ).css( {
top: e.pageY - 10, left: e.pageX + 30
} );
} );
I think I have to kill mousemove! How to do that please?
thanks

How do you know which substitutions to make to cancel out a term?
How do you know which substitutions to make to cancel out a term?
I am doing problem B45 from Ivan Niven's "Maxima and Minima Without
Calculus" which says:
"Consider the quadratic polynomial $f(x, y)=ax^2+2bxy+cy^2+dx+cy+k$ ,
where the coefficients are real constants with $a>0$ and $c>0$ . In case
$b \not =0$ , verify that the transformation $x=X-by/a$ produces a
quadratic polynomial $f(X-by/a , y)$ with no $Xy$ term."
The reason why he didn't want an $Xy$ terms is because if there is none
then the function is easy to minimize by minimizing the two variables
separately. My question is, what steps led to the substitution $x=X-by/a$?
How did he know that making this substitution would lead you to having no
$Xy$ term? How can this method be extended more generally to other
functions? Thanks.

Missing values after joining tables in SQLite
Missing values after joining tables in SQLite
This is relationship between tables in SQLite database. There I am trying
to join 5 tables.
SELECT * FROM r_ele
WHERE r_ele.value LIKE '‚Å‚à%'
Query above returns this result(which is ok). The table next to this
missing words in red!
But when I try join tables, some values are missing.
SELECT e.id AS entry_id,
re.value AS re_value,
GROUP_CONCAT(DISTINCT ke.value) AS ke_value,
GROUP_CONCAT(DISTINCT g.value) AS g_value
FROM (entry e
INNER JOIN k_ele ke ON e.id = ke.fk
INNER JOIN r_ele re ON e.id = re.fk
INNER JOIN sense s ON e.id = s.fk
INNER JOIN gloss g ON s.id = g.fk)
WHERE g.lang IS NULL AND re_value LIKE '‚Å‚à%'
GROUP BY re.value
ORDER BY re_value;
Result:
What I am doing wrong? What should I do in order to avoid missing some
values from table 'r_ele'?

$.ajax()function with json data from javascript array to a php processing
file
i trying to use json for the first time with $.ajax() i got the values of
checkboxes and other needed data to a php file for processing and posting
to mysqldb through an array for the data section of $.ajax() function but
would get an empty array[] on my php file. When i try using javascript
debugging tool from my browser i got the reprot

on my php processing file i did print_r on the json data but got an

A basic doubt on linear maps
A basic doubt on linear maps
Let $f$ be a linear map from $V$ to its field set, say $F$. Now if
$f(v)=0$ does it necessarily imply that $v=0$. I don't think so. $v=0$ is
one solution, but it need not be the only solution because $f$ need not be
one-to-one. Is this correct ?

htaccess simplified and remove need for trailing a slash
htaccess simplified and remove need for trailing a slash
I am writing my very first htaccess and would like help cleaning it up and
understanding it. The first issue I am having is with mulitple parameters.
my current setup looks like:
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !/(_modules|css|files|ico|img|js)/
RewriteRule ^([^/]*)/([^/]*)$ index.php?p1=$1 [L]

RewriteRule ^([^/]*)/([^/]*)$ index.php?p1=$1&p2=$2&p3=$3&p4=$4 [L]
Is there a way to simplify this to handle up to a maximum of 4 parameters
with all of them being optional? Which leads me to me next problem that it
seems that if you need to have a trailing slash after the parameters
unless you are using all 4 parameters.
In short I would like my urls to look like this...

});
I need to disable click of the Youtube iframe or set difference click.
I tried to put a div in front the iframe but it doesn't work.
Here is my code:
$(".youtube").each(function () {
var div = this;
var offset = $(this).offset();
var x = offset.left;
var y = offset.top;
var height = $(this).height();
var width = $(this).width();
var divInFront = '<div style="position:absolute; height:' + height +
'; width:' + width + '; top:' + y + '; left:' + x + ';" ></div>';
$("body").append(divInFront);
});

Adding an Existing Java Project to Git repo
Adding an Existing Java Project to Git repo
Alright, I'm about to go completely insane about this.
I'm trying to add an existing java project from the workspace to my git
repository. I do the usual, it's all:
git init/committed/remote origin/pushed
however
The only thing appearing is an empty folder. Why? I've been googling for
far too long than I dare to admit but without success.
How do I add a folder, with quite a lot of subfolders, to my github repo.
I'm using git version 1.8.3.2 on Linux
Thanks in advance.

convert co-ordinate d-m-s to decimal degrees using awk
convert co-ordinate d-m-s to decimal degrees using awk
My input is a tab-separated text file with lat long in D-M-S. I require
output to be in decimal degrees I have code in php, but this is very slow
to calculate. Can this be done quicker using awk?
node name id latitude longitude seq
nodex name1 70 N53-24-31.126 W6-20-46.982 59126
nodex name2 173 N53-20-28.885 W6-14-52.400 16190X
nodex name3 173 N53-20-28.885 W6-14-52.400 16191T
Formula:
if ($dirLat == 'N') {$signLat = '+';} Else {$signLat = '-';}
if ($dirLat == 'E') {$signLon = '+';} Else {$signLon = '-';}
$latitudeDecimalDeg = $signLat . ($degLat + ($minLat/60) + ($secLat/3600));
$longitudeDecimalDeg = $signLon . ($degLon + ($minLon/60) + ($secLon/3600));

@font-face issues with Firefox
@font-face issues with Firefox
It may only be an issue with Firefox but whenever visiting the site using
www. as a prefix the embedded fonts don't load even when using an absolute
path.
I don't know if there are ways to reinforce this using CSS or there is
some kind of DNS issues with the www. that I need to edit, but I'm all out
of options of how to fix this.
could anyone share some help with this?

How to use generic delegates in C#
How to use generic delegates in C#
I have these classes:
public interface IPerson
{
string Name { get; set; }
}
public class Person : IPerson
{
public string Name { get; set; }
}
public interface IRoom
{
List<Furniture> Furnitures { get; set; }
List<Person> People { get; set; }
}
public class Room : IRoom
{
public List<Furniture> Furnitures { get; set; }
public List<Person> People { get; set; }
}
public enum Furniture
{
Table,
Chair
}
And I have this extension method:
public static void Assign<T>(this IRoom sender, Func<IRoom,ICollection<T>>
property, T value)
{
// How do I actually add a Chair to the List<Furniture>?
}
And I want to use it like this:
var room = new Room();
room.Assign(x => x.Furnitures, Furniture.Chair);
room.Assign(x => x.People, new Person() { Name = "Joe" });
But I have no idea how to add T to ICollection.
Trying to learn generics and delegates. I know
room.Furnitures.Add(Furniture.Chair) works better :)
