39,758,094 | Clearing Tensorflow GPU memory after model execution | <p>I've trained 3 models and am now running code that loads each of the 3 checkpoints in sequence and runs predictions using them. I'm using the GPU.</p>
<p>When the first model is loaded it pre-allocates the entire GPU memory (which I want for working through the first batch of data). But it doesn't unload memory when it's finished. When the second model is loaded, using both <code>tf.reset_default_graph()</code> and <code>with tf.Graph().as_default()</code> the GPU memory still is fully consumed from the first model, and the second model is then starved of memory.</p>
<p>Is there a way to resolve this, other than using Python subprocesses or multiprocessing to work around the problem (the only solution I've found on via google searches)?</p>

I use fetchmail to fetch my e-mail and process it using procmail. Some of the email services (etc. gmx.com, outlook.com, etc) do not seem to require the certificate and the fingerprint checked. Some others, such as inbox.com or gmail.com do. I am wondering if there is a security hole in going from the latter kind to the former. What is the value of the certificate checking?

how can I achieve this?
I gone through several reseaches, with the help of `foreign key` I can store multiple values in single column but How can i use *foreign key* in `Where clause` to achieve `expected o/p`.

<ul>
<li>There are two "roles" in the system, users will have one of the
roles. One role should allows access to some APIs (call it "VIEW"),
the other role allows access to other APIs</li>
<li>All users are in Active Directory, so if I have a username, I can check what role they are in- Some clients are on Windows boxes, the others are on Linux</li>
<li>I would like to persist the session so I don't have to look up AD for every API call</li>
<li>I would like single sign on. On the Windows machines, I don't require them to enter user and pass as I already can retrieve their username using Windows Authentication.</li>

39,776,819 | Function to normalize any number from 0 - 1 | <p>I'm trying to make a function that takes a number and normalizes it from 0 - 1 between its min and max bounds. For example: </p>
<p>If I want to normalize a value of 10 between 5 to 15, I call this:</p>
<p><code>val = 10; normalize(val, 5, 15);</code> Returns 0.5</p>
<p>normalizing a value 0 between -10 and 5</p>
<p><code>val = 0; normalize(val, -10, 5);</code> Returns 0.666</p>
<p>This is the function I came up with:</p>
<pre><code>function normalize(val, min, max){
// Shift to positive to avoid issues when crossing the 0 line
if(min < 0){
max += 0 - min;
val += 0 - min;
min = 0;
}
// Shift values from 0 - max
val = val - min;
max = max - min;
return Math.max(0, Math.min(1, val / max));
}
</code></pre>
<p>My question is: Is this the most efficient method to normalize a 1-dimensional value? I'm going to be calling this function a few thousand times per frame at 60fps, so I'd like to have it as optimized as possible to reduce the burden of calculation. I've looked for normalization formulas, but all I find are 2- or 3-dimensional solutions.</p>

<pre><code>class SomethingRecord(Record):
description = 'This records something'

<p>I use <code>ast</code> to locate the <code>description</code> line number, and I use some code to change the original file with new description string base on the line number. So far so good.</p>
<p>Now the only issue is <code>description</code> occasionally is a multi-line string, e.g.</p>
<pre><code> description = ('line 1'
'line 2'
'line 3')
</code></pre>
<p>or</p>
<pre><code> description = 'line 1' \
'line 2' \

<pre><code> description = 'new value'
'line 2' \
'line 3'
</code></pre>
<p>and the code is broken. I figured that if I know both the lineno of start and end/number of lines of <code>description</code> assignment I could repair my code to handle such situation. How do I get such information with Python standard library?</p>

I know that the scala examples available online are similar (<a href="https://databricks-prod-cloudfront.cloud.databricks.com/public/4027ec902e239c93eaaa8714f173bcfc/6122906529858466/431554386690884/4814681571895601/latest.html" rel="noreferrer">here</a>), but I was hoping for a direct walkthrough in python language. </p>
<p>My specific case: I am loading in avro files from S3 in a zeppelin spark notebook. Then building df's and running various pyspark & sql queries off of them. All of my old queries use sqlContext. I know this is poor practice, but I started my notebook with </p>
<p><code>sqlContext = SparkSession.builder.enableHiveSupport().getOrCreate()</code>. </p>
<p>I can read in the avros with </p>
<p><code>mydata = sqlContext.read.format("com.databricks.spark.avro").load("s3:...</code> </p>
<p>and build dataframes with no issues. But once I start querying the dataframes/temp tables, I keep getting the "java.lang.NullPointerException" error. I think that is indicative of a translational error (e.g. old queries worked in 1.6.1 but need to be tweaked for 2.0). The error occurs regardless of query type. So I am assuming </p>
<p>1.) the sqlContext alias is a bad idea </p>
<p>and </p>
<p>2.) I need to properly set up a sparkSession. </p>
<p>So if someone could show me how this is done, or perhaps explain the discrepancies they know of between the different versions of spark, I would greatly appreciate it. Please let me know if I need to elaborate on this question. I apologize if it is convoluted. </p>

39,781,115 | Visual Studio 2015: "tsc.exe" exited with code 1 | <p>I was formerly using Visual Studio 2013 for a web TypeScript project. Upgraded to Visual Studio 2015 Update 3, and when building the project, I get </p>
<pre><code>"tsc.exe" exited with code 1
</code></pre>
<p>There are a million of these errors on the web. One suggested I install Microsoft.TypeScript.MSBuild and Microsoft.TypeScript.Compiler via NPM, which I did.</p>
<p>When I dig into the Output (making it verbose), I see this:</p>
<pre><code>1> C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.6\tsc.exe --project "F:\depot\depot\code\main\web\CedarsReport\tsconfig.json" --listEmittedFiles
1> F:\depot\depot\code\main\web\CedarsReport\error TS5023:Build:Unknown compiler option 'listemittedfiles'.
</code></pre>
<p>Questions:
1) Why is it using TypeScript 1.6? I installed "TypeScript 1.8.4 for Visual Studio 2015."</p>
<p>2) Where is the --listEmittedFiles option coming from, and how can I disable it?</p>
<p>3) If I go to Project > Properties > TypeScript Build, it says:
":One or more tsconfig.json files detected. Project properties are disabled."
So I tried moving my tsconfig.json file to the desktop, deleting the one in the project folder. Quit Visual Studio 2015 and restarted, did clean and rebuild, and same error message. Why does it think there is still a tsconfig.json file when there isn't one?!</p>
<p>Even if you can't answer all questions, answering any would be welcome, esp. #2.</p>

39,782,506 | Deploying basic Angular 2 app to Google App Engine | <p>I can use Angular 2 to create basic front-end applications and can use python to create back-ends with endpoints on Google App engine. I can't however seem to figure out how to put the two together and deploy them with the cloud SDK.</p>
<p>Here is a basic example where I can't even host a simple angular2 app with no back-end calls on GAE. I have taken the dist folder after building with angular2 CLI and tried to connect to it with the app.yaml file. It seems to work in the browser developer (dev_appserver.py app.yaml) although I get some 404 errors in SDK with the GET requests to do with my index.html file I think. I then create a blank index.yaml file and try to deploy it but get a 404 Error at the appspot.com location. This is the app.yaml file:</p>

<p>I really have no idea what I am doing wrong. Do I need some kind of a main.application python back-end to connect to the dist files or? Do I need to include node modules or some other kind or files from Angular2? Any help would be massively appreciated! Thanks</p>

39,786,134 | Does PHP7's PDO ext read the entire result set into memory? | <p>I have noticed since I upgraded to PHP7 that some SQL statements no longer work and instead run out of memory.</p>
<p>I have this code:</p>
<pre><code>$query = Yii::$app->db->createCommand('select * from tbl_title')->query();
while ($row = $reader->read()) {
var_dump($row);
exit();
}
</code></pre>
<p>And Yii2's database abstraction is just an extremely thin layer over PDO's and does not do anything extra. <code>query()</code> does nothing extra except add a line to a log file (Yii2's) for profiling and <code>reader->read()</code> just calls the PDO stream's <code>fetch()</code> function.</p>
<p>But it runs out of memory quoting the size (space used) of my table, i.e. trying to allocate 385 MB of process memory:</p>
<blockquote>
<p>Allowed memory size of 134217728 bytes exhausted (tried to allocate 385883840 bytes)</p>
</blockquote>
<p>As a spanner, if I use a query whose result set fits entirely in the 128 MB limit of the PHP process works.</p>

39,788,839 | JQuery returns false after return true? | <p>I'm little confused by behaviour of my functions in <code>JQuery</code>. The thing is that <code>is_airport</code> function decides, whether the location is an airport using JSON of airports. </p>
<p>Everything seems to work correctly, JSON is correctly parsed etc. As you can see there is a loop which is used for detecting, whether the <code>destination_id</code> is in airports JSON keys. It is. <strong>It alerts 'OK'</strong> but returns <code>false</code> instead of <code>true</code>. </p>
<p>If there was an <code>AJAX</code> instead of <code>each</code> function, I would expect this behaviour because of async. But why it happens here?</p>
<pre><code>function is_airport(destination_id){
var json_storage = $("#locations-json");
var airports = JSON.parse(json_storage.attr("data-airports"));
$.each(airports,function(id,name){
console.log(id,destination_id,name);

alert('ok');
return true
}
});
return false
}

console.log(is_airport(5));)}

39,789,818 | Best practice for passing enum params in Web API | <p>I have a RESTful Web API project, and I have 2 different Enum scenarios that I'm unsure of re best practice.</p>
<p><strong>Scenario 1 : Straightforward Enum Param</strong></p>
<p>My API method requires a parameter called <code>ruleType</code>, with valid values being <code>EmailAddress</code> and <code>IPAddress</code>.
My enum within the Web API project looks like this:</p>
<pre><code>public enum RuleType
{
None = 0,
EmailAddress = 1,
IPAddress = 2
}
</code></pre>
<p>My question for this scenario is, should I use <code>?ruleType=EmailAddress</code> in my request to the API (which automatically binds that value to my <code>RuleType</code> property within the API method)? If so, how best to validate that the <code>RuleType</code> param sent, is a valid RuleType Enum value?</p>
<p><strong>Scenario 2 : Multiple Enum Values for a Single Param</strong></p>
<p>My API method has an optional <code>fields</code> param, which is allows you to specify any additional data that should be returned. E.g. <code>&fields=ruleOwner,rule</code>. This would return those 2 extra bits of data in the response.</p>
<p>I have an enum in the Web API project which relates to each possible <code>field</code> that may be requested, and at present, I am splitting the comma separated fields param, then looping through each string representation of that enum, parsing it to the equivalent enum, resulting in a list of Enum values which I can then use within my API to retrieve the relevant data.</p>
<p>This is the Enum:</p>
<pre><code>public enum OptionalField
{
None = 0,
RuleOwner = 1,
Rule = 2,
etc.
}
</code></pre>
<p>What would be best practice here? I was looking into bitwise enums, so a single value is sent in the API request which resulted in any combination of <code>fields</code> but didn't know if this would work well with a Web API, or if there's generally a better way to go about this?</p>

39,799,640 | When writing a PowerShell module in C#, how do I store module state? | <p>I'm writing a PowerShell module in C# that connects to a database. The module has a <code>Get-MyDatabaseRecord</code> cmdlet which can be used to query the database. If you have a <code>PSCredential</code> object in the variable <code>$MyCredentials</code>, you can call the cmdlet like so:</p>
<pre><code>PS C:\> Get-MyDatabaseRecord -Credential $MyCredentials -Id 3
MyRecordId : 3
MyRecordValue : test_value
</code></pre>
<p>The problem is, having to specify the <code>Credential</code> parameter every time that you call <code>Get-MyDatabaseRecord</code> is tedious and inefficient. It would be better if you could just call one cmdlet to connect to the database, and then another to get the record:</p>
<pre><code>PS C:\> Connect-MyDatabase -Credential $MyCredentials
PS C:\> Get-MyDatabaseRecord -Id 3
MyRecordId : 3
MyRecordValue : test_value
</code></pre>
<p>In order for that to be possible, the <code>Connect-MyDatabase</code> cmdlet has to store the database connection object somewhere so that the <code>Get-MyDatabaseRecord</code> cmdlet can obtain that object. How should I do this?</p>
<h2>Ideas I've thought of</h2>
<h3>Use a static variable</h3>
<p>I could just define a static variable somewhere to contain the database connection:</p>
<pre><code>static class ModuleState
{
internal static IDbConnection CurrentConnection { get; set; }
}
</code></pre>
<p>However, global mutable state is usually a bad idea. Could this cause problems somehow, or is this a good solution?</p>
<p>(One example of a problem would be if multiple PowerShell sessions somehow shared the same instance of my assembly. Then all of the sessions would inadvertently share a single <code>CurrentConnection</code> property. But I don't know if this is actually possible.)</p>
<h3>Use PowerShell module session state</h3>
<p>The MSDN page "<a href="https://msdn.microsoft.com/en-us/library/ms714451%28v=vs.85%29.aspx">Windows PowerShell Session State</a>" talks about something called session state. The page says that "session-state data" contains "session-state variable information", but it doesn't go into detail about what this information is or how to access it.</p>
<p>The page also says that <a href="https://msdn.microsoft.com/en-us/library/system.management.automation.sessionstate%28v=vs.85%29.aspx">the <code>SessionState</code> class</a> can be used to access session-state data. This class contains a property called <a href="https://msdn.microsoft.com/en-us/library/system.management.automation.sessionstate.psvariable%28v=vs.85%29.aspx"><code>PSVariable</code></a>, of type <a href="https://msdn.microsoft.com/en-us/library/system.management.automation.psvariableintrinsics%28v=vs.85%29.aspx"><code>PSVariableIntrinsics</code></a>.</p>
<p>However, I have two problems with this. The first problem is that accessing the <code>SessionState</code> property requires me to inherit from <code>PSCmdlet</code> instead of <code>Cmdlet</code>, and I'm not sure if I want to do that.</p>
<p>The second problem is that I can't figure out how to make the variable private. Here's the code that I'm trying:</p>
<pre><code>const int TestVariableDefault = 10;
const string TestVariableName = "TestVariable";
int TestVariable
{
get
{
return (int)SessionState.PSVariable.GetValue(TestVariableName,
TestVariableDefault);
}
set
{
PSVariable testVariable = new PSVariable(TestVariableName, value,
ScopedItemOptions.Private);
SessionState.PSVariable.Set(testVariable);
}
}
</code></pre>
<p>The <code>TestVariable</code> property works just as I would expect. But despite the fact that I'm using <code>ScopedItemOptions.Private</code>, I can still access this variable at the prompt by typing in <code>$TestVariable</code>, and the variable is listed in the output of <code>Get-Variable</code>. I want my variable to be hidden from the user.</p>
