35,874,461 | Using the contents of a Textbox as arguments for Process.Select | I'm a new programmer who is just getting into Visual Basic. I'm trying to create a simple application that would let me mount ISO files using the built in Windows PowerShell.

If OpenFileDialog1.ShowDialog = DialogResult.OK Then
TextBox1.Text = OpenFileDialog1.FileName
Me.ErrorProvider1.SetError(Me.TextBox1, "Looks Valid")
End If
End Sub

Process.Start("powershell", "Mount-DiskImage 'C:\ISO\MY Magic ISO.iso'")
Else

My program is simple, you pick a file from the dialog, and if the file is valid, it is mounted with powershell.
My question is how I would go about dynamically changing the "C:\ISO\MY Magic ISO.iso" filepath, using the contents of Textbox1. Is this possible? Any help would be greatly appreciated, and I am incredibly sorry if this has been asked before!

35,876,508 | Evaluate multiple scores on sklearn cross_val_score | <p>I'm trying to evaluate multiple machine learning algorithms with sklearn for a couple of metrics (accuracy, recall, precision and maybe more).</p>
<p>For what I understood from the documentation <a href="http://scikit-learn.org/stable/modules/model_evaluation.html#" rel="noreferrer">here</a> and from the source code(I'm using sklearn 0.17), the <a href="http://scikit-learn.org/stable/modules/generated/sklearn.cross_validation.cross_val_score.html#sklearn.cross_validation.cross_val_score" rel="noreferrer">cross_val_score</a> function only receives one scorer for each execution. So for calculating multiple scores, I have to :</p>
<ol>
<li>Execute multiple times</li>
<li><p>Implement my (time consuming and error prone) scorer</p>
<p>I've executed multiple times with this code :</p>
<pre><code>from sklearn.svm import SVC
from sklearn.naive_bayes import GaussianNB
from sklearn.tree import DecisionTreeClassifier
from sklearn.cross_validation import cross_val_score
import time
from sklearn.datasets import load_iris
iris = load_iris()
models = [GaussianNB(), DecisionTreeClassifier(), SVC()]
names = ["Naive Bayes", "Decision Tree", "SVM"]
for model, name in zip(models, names):
print name
start = time.time()
for score in ["accuracy", "precision", "recall"]:
print score,
print " : ",
print cross_val_score(model, iris.data, iris.target,scoring=score, cv=10).mean()
print time.time() - start
</code></pre></li>
</ol>
<p>And I get this output: </p>
<pre><code>Naive Bayes
accuracy : 0.953333333333
precision : 0.962698412698
recall : 0.953333333333

precision : 0.983333333333
recall : 0.98

35,879,780 | Creating game, currently using SQL Server to store data, looking for better alternatives | <p>I have been using SQL Server 2014 to store a DB for the game to use with multiple tables...it's a football game so there are quite a few tables...players, coaches, owners, GMs, scouts, teams, etc...</p>
<p>The question I have is will end users need to have SQL server installed to utilize the DBs in the game? If so, I need to switch to a different option and am wondering what the best option would be for storing large amounts of data which will not require end users to have something special installed to utilize them? </p>
<p>CSV seems the obvious easy answer but I think that would be too much data for a CSV file to handle well.</p>

<pre><code>var str = "abc";
var str2 = str.split(" ").join("").split("");

<p>My question is why str2 is being changed even though it is not being reversed?</p>
<p>This is very upsetting to me, but I have a guess as to why this is happening. The tmp is just a pointer to the original str2, and when I call reverse() on tmp, it actually reverses str2. </p>
<p>Even if that really is what's happening, I still feel like it is a very counterintuitive way for a language to work. </p>

35,888,183 | Why hash maps in Java 8 use binary tree instead of linked list? | <p>I recently came to know that in Java 8 hash maps uses binary tree instead of linked list and hash code is used as the branching factor.I understand that in case of high collision the lookup is reduced to O(log n) from O(n) by using binary trees.My question is what good does it really do as the amortized time complexity is still O(1) and maybe if you force to store all the entries in the same bucket by providing the same hash code for all keys we can see a significant time difference but no one in their right minds would do that.</p>
<p>Binary tree also uses more space than singly linked list as it stores both left and right nodes.Why increase the space complexity when there is absolutely no improvement in time complexity except for some spurious test cases.</p>

<p>Another question is I want to write a list comprehension to count non-zero element. Use <code>alist</code> as an example, I want to return a list called <code>count</code> containing 1 or 0: 1 if the element in <code>alist</code> is not zero and zero is the element in <code>alist</code> is zero. So the result should be:</p>
<pre><code>alist = [1,2,3,4,5,6,0,9,9,4,5,0,0,2,3,0,9,6]
count = [1,1,1,1,1,1,0,1,1,1,1,0,0,1,1,0,1,1]

35,900,737 | Support Multiple Label Printers | <p>We develop a desktop business application where we are going to add support to label printing.</p>
<p>As there are lots of different printer makes and models out there, I want to discuss here what would be the best approach to manage all these different models/makes.</p>
<p>Considering some printers use the windows spool (Brother, Dymo, etc) and other ones uses ZPL, EPL, etc. (Zebra, Argox, etc) or anything else, what would be the best approach to support different models.</p>
<p>I was thinking about getting the printer description after the user selects its desired printer, and from them, my code will look for the specific implementation and if does not find it, alert the user.</p>
<p>However, the user can change label description if I understand. </p>
<p>How can I manage this?</p>

35,902,847 | What C++ standard has better of COM? | <p>I have see such answer:</p>
<blockquote>
<p>COM is a technique of it's own. It fulfills some special needs but
violates a lot of good engineering principles. E.g solid. The standard
has better ways than using COM. – mkaes</p>
</blockquote>
<p>Very interesting to know what is that "better ways"?</p>
<p>We use in our project IUnknown base class, but not COM technology itself.
IUnknown allows us:</p>
<ol>
<li>have nice specified interface abstract classes;</li>
<li>use its add()/release() as basis for intrusive smart ptrs;</li>
<li>use mechanism of QueryInterface() to be more effective than dynamic_cast;</li>
</ol>
<p>Okay, exists boost::intrusive_ptr but it is not in the standard so far. And even if it was there, this will be separate class to solve task of intrusive smart ptr. Assuming it is there, yes I could do something as</p>
<pre><code>interface ITable : intrusive_ptr {}
interface IField : intrusive_ptr {}
</code></pre>
<p>But what about QueryInterface() mechanism?</p>
<p>P.S. This question is NOT about COM at all.</p>

35,914,081 | Group arrays according to their keys and remove duplicates (2 dimensional arrays PHP) | I have three arrays as follow:
$a=Array ( [0] => 'member0' [1] => 'member1' [2] => 'member2' [3] => 'member1');
$b=Array ( [0] => 'id0' [1] => 'id1' [2] => 'id2' [3] => 'id1');
$c=Array ( [0] => 'tf0' [1] => 'tf1' [2] => 'tf2' [3] => 'tf1');
I would like to group their values according to their keys in a 2 dimensional array to output the following:
$2dim_array=array(array('member0','id0','tf0'),array('member1','id1','tf1'),array('member2','id2','tf2'),array('member1','id1','tf1'));
After, I would like to remove any duplicate array inside of the previous 2 dimensional array and output something like this:
$remove_duplicates=array(array('member0','id0','tf0'),array('member1','id1','tf1'),array('member2','id2','tf2'));
How can I do this?. Thanks.
Note: The arrays of this example only contain 3 elements each, but the length of my arrays can be variable (undefined number of keys). | <php><multidimensional-array><duplicates><grouping> | 2016-03-10 10:39:06 | LQ_EDIT |

35,919,555 | Mainactivity appears to exist twice or more after restarting app | I have an app with an activity sending a broadcast to another activity.
Everything appears to be fine. But if I close my app and open it again,
this broadcasts seems to get send more than once. In fact it gets send
as often I reopened the app. If I print out "this" right before sending the broadcast I get different instances.
Why could this happen? Why is the activity not dying? I checked, onDestroy get's called. BUT I have a background-service, which I dont stop, when the app is closed. Is it therefore? Can I reopen the old activity, when starting the app instead of opening a new one?
Setting launchmode in the Manifest to singleTask or singleInstance didn't work either.
