<p>If you assign <code>this</code> reference to a member variable, you have a recursion. Yes, it doesn't matter how many <code>s</code>'s you'll add, because they are always the same object, which is <code>this</code> object. It's the same as if you wrote:</p> <pre><code>this.this.this.this.this.this.x++; </code></pre> <p>Function <code>f()</code> returns reference to <code>this</code> object after doing some other operations on it. It's a common design pattern in Java, called <a href="http://www.tutorialspoint.com/design_pattern/builder_pattern.htm" rel="nofollow">builder</a>. Adding ability to do <code>a4.f().g();</code> to a class is called <a href="http://stackoverflow.com/a/21180314/5922757">method chaining</a>. In other words, <code>f()</code> is <code>this</code> object at the end of the call, just like <code>s</code> is, so you can do:</p> <pre><code>a1.f().f().f().f().f().f(); </code></pre> <p>And it means you just called <code>f()</code> function from <code>a1</code> object 6 times.</p>

What are some reasons I might be receiving this "Symbol not defined" error in Visual Studio 2005 (screenshot included) <p>When debugging my VS2005 project, I get the following error when I attempt to step into the function that returns the <em>vScenarioDescriptions</em> local variable it's struggling with...</p> <p><em><img src="http://people.ict.usc.edu/~crotchett/images/symbolnotdefined.JPG" alt="image no longer available"></em></p> <p>As I continue to walk through the code and step into functions, it appears I'm getting this error other local variables as well.

How to rollback in EF4 for Unit Test TearDown? <p>In my research about rolling back transactions in EF4, it seems everybody refers to <a href="http://blogs.msdn.com/alexj/archive/2009/01/11/savechanges-false.aspx" rel="nofollow noreferrer">this blog post</a> or offers a similar explanation. In my scenario, I'm wanting to do this in a unit testing scenario where I want to rollback practically everything I do within my unit testing context to keep from updating the data in the database (yeah, we'll increment counters but that's okay). In order to do this, is it best to follow the following plan? Am I missing some concept or anything else major with this (aside from my <code>SetupMyTest</code> and <code>PerformMyTest</code> functions won't really exist that way)?</p> <pre><code>[TestMethod] public void Foo { using (var ts = new TransactionScope()) { // Arrange SetupMyTest(context); // Act PerformMyTest(context); var numberOfChanges = context.SaveChanges(SaveOptions.AcceptAllChangesAfterSave); // if there's an issue, chances are that an exception has been thrown by now. // Assert Assert.IsTrue(numberOfChanges &gt; 0, "Failed to _____"); // transaction will rollback because we do not ever call Complete on it } } </code></pre>

How to aggregate values over a bigger than RAM gzip'ed csv file? <p>For starters I am new to bioinformatics and especially to programming, but I have built a script that will go through a so-called VCF file (only the individuals are included, one clumn = one individual), and uses a search string to find out for every variant (line) whether the individual is homozygous or heterozygous.</p> <p>This script works, at least on small subsets, but I know it stores everything in memory. I would like to do this on very large zipped files (of even whole genomes), but I do not know how to transform this script into a script that does everything line by line (because I want to count through whole columns I just do not see how to solve that).</p> <p>So the output is 5 things per individual (total variants, number homozygote, number heterozygote, and proportions of homo- and heterozygotes). See the code below:</p> <pre><code>#!usr/bin/env python import re import gzip subset_cols = 'subset_cols_chr18.vcf.gz' #nuc_div = 'nuc_div_chr18.txt' gz_infile = gzip.GzipFile(subset_cols, "r") #gz_outfile = gzip.GzipFile(nuc_div, "w") # make a dictionary of the header line for easy retrieval of elements later on headers = gz_infile.readline().rstrip().split('\t') print headers column_dict = {} for header in headers: column_dict[header] = [] for line in gz_infile: columns = line.rstrip().split('\t') for i in range(len(columns)): c_header=headers[i] column_dict[c_header].append(columns[i]) #print column_dict for key in column_dict: number_homozygotes = 0 number_heterozygotes = 0 for values in column_dict[key]: SearchStr = '(\d)/(\d):\d+,\d+:\d+:\d+:\d+,\d+,\d+' #this search string contains the regexp (this regexp was tested) Result = re.search(SearchStr,values) if Result: #here, it will skip the missing genoytypes ./. variant_one = int(Result.group(1)) variant_two = int(Result.group(2)) if variant_one == 0 and variant_two == 0: continue elif variant_one == variant_two: #count +1 in case variant one and two are equal (so 0/0, 1/1, etc.) number_homozygotes += 1 elif variant_one != variant_two: #count +1 in case variant one is not equal to variant two (so 1/0, 0/1, etc.) number_heterozygotes += 1 print "%s homozygotes %s" % (number_homozygotes, key) print "%s heterozygotes %s" % (number_heterozygotes,key) variants = number_homozygotes + number_heterozygotes print "%s variants" % variants prop_homozygotes = (1.0*number_homozygotes/variants)*100 prop_heterozygotes = (1.0*number_heterozygotes/variants)*100 print "%s %% homozygous %s" % (prop_homozygotes, key) print "%s %% heterozygous %s" % (prop_heterozygotes, key) </code></pre> <p>Any help will be much appreciated so I can go on investigating large datasets, thank you :)</p> <p>The VCF file by the way looks something like this: INDIVIDUAL_1 INDIVIDUAL_2 INDIVIDUAL_3 0/0:9,0:9:24:0,24,221 1/0:5,4:9:25:25,0,26 1/1:0,13:13:33:347,33,0</p> <p>This is then the header line with the individual ID names (I have in total 33 individuals with more complicated ID tags, I simplified here) and then I have a lot of these information lines with the same specific pattern. I am only interested in the first part with the slash so hence the regular epxression.</p>

Sync branches in git <p>I'm sure this is a simple one but I haven't been able to find the answer online, even after much Googling.</p> <p>I have Git installed on my machine, for which I followed the tutorial on the Github site. Following this made my machine master. Now, I need to work on a different branch. So I created a new branch on the site. Problem: this new branch isn't showing up in the Bash window, and when I try to switch to it, it isn't recognized. A coworker created his branch and it isn't on my machine either. </p> <p>How can I synchronize the list of branches on the site with my machine?</p> <p>Thanks!</p>

Reduce Transparency setting in OS X makes white text in NSButton in popover disappear <p>I'm working on an OS X app that involves popovers with web views in them. The web views have <code>drawsBackground</code> set to <code>NO</code>. Sometimes there are buttons in these popovers, on top of the web views. These buttons have custom background colors and have their text colors set via <code>NSAttributedString</code>. But when the Reduce Transparency setting is on in System Preferences, the white text disappears. If the text is any other color, it shows up - even clear (though faintly).</p> <p><a href="https://github.com/tomhamming/nsbutton_title_disappear" rel="nofollow">See here</a> for an example project on GitHub demonstrating the problem.</p> <p>What is going on here?</p> <p><b>Update:</b> I talked to an engineer at WWDC 2016 about this, and he confirmed it was a bug. I filed a radar. He did manage to fix it in my code by setting the appearance of the button in question to <code>NSAppearanceNameAqua</code>.</p>

<p>For detecting CTRL + F:</p> <pre><code>event.ctrlKey == true &amp;&amp; event.keyCode == Keyboard.F </code></pre> <p>where 'event' is of course a KeyBoardEvent.</p> <p>As for the F3 question: the code you wrote will work as long as the flash application has focus. The F3 key command will then also not be routed to the browser. So what you need to do, is make sure that your application has focus when the user hits F3. How you solve this will depend on your JavaScript implementation. You could use ExternalInterface to tell the browser that the app is ready and than focus on the app. Or in Javascript you could catch the keyboard event, prevent its default behavior, and then call the function on the Flash app (again through ExternalInterface).</p> <p>To get you started, here's a little JQuery snippet for preventing the default F3 behaviour:</p> <pre><code>$('body').keyup(function(event) { if (event.keyCode == '114') event.preventDefault(); } </code></pre>

<p>You need to retain a copy of the AdMob AdViewController as Admob no longer does this itself.</p> <p>In your viewcontroller.h add something like</p> <pre><code>IBOutlet AdViewController *localAdViewController; </code></pre> <p>inside the @interface section, and add</p> <pre><code>@property (nonatomic, retain) AdViewController *localAdViewController; </code></pre> <p>afterwards.</p> <p>Then add a link in IB from File's owner to your localAdViewController in AdViewController.</p> <p>Should work fine then on.</p>

SSL not working between Linux and Windows <p>I have gone through loads of material present on internet for SSL. I followed the steps and created self signed certificate on server (linux) using keytool. Server keystore was already having an entry as ( CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=Unknown), my new certificate was second entry as ( CN=Server, OU=Server, O=Server, L=Server, ST=Server, C=Server ). Then I exported the certificate(.cer) using keytool and copied same on my client(windows). I then imported server generated certificate to client trustore. Now when I try to communicate using SSL it fails everytime. I turned on SSL debug on client. Below is the log</p> <pre><code>adding as trusted cert: Subject: CN=Server, OU=Server, O=Server, L=Server, ST=Server, C=Server Issuer: CN=Server, OU=Server, O=Server, L=Server, ST=Server, C=Server

GXT get value of TextArea without focus loss <p>I have a GXT 3 TextArea on which I catch copy-paste events. On this event, I would like to get the text that is inside the textarea.</p> <p><strong>Problem</strong> : the textarea still has the focus so the value is not updated. Hence, <code>getValue()</code> returns an empty string...</p> <p>I tried to call <code>getValue()</code> <code>getCurrentValue()</code> <code>flush()</code> <code>validate()</code>. </p> <p>I also tried to extend <code>TextArea</code> to have access to <code>blur()</code> method and call it before getting the value : it makes no difference.</p> <p>Any solution? (even solution with GWT components would be appreciated).</p>

<p>The API and all client libraries in turn will return actual objects when they are queried for. However, when referencing an object in the API you do so with just the object's ID. </p> <p>Therefore, in your code above, <code>workspace</code> holds the actual workspace object. In order to use that in a query you must use <code>workspace: workspace.id</code>. </p> <p>You can see a working example of <code>.find_by_workspace()</code> <a href="https://github.com/Asana/ruby-asana/blob/master/examples/personal_access_token.rb" rel="nofollow">here</a>:</p> <pre><code>puts "My Workspaces:" client.workspaces.find_all.each do |workspace| puts "\t* #{workspace.name} - tags:" client.tags.find_by_workspace(workspace: workspace.id).each do |tag| puts "\t\t- #{tag.name}" end end </code></pre>

<p>Threads do not work, abstain from that approach.</p> <p>Creating several threads fails, as you have noticed, because only one thread has a current OpenGL context. In principle, you <em>could</em> make the context current in each worker thread before calling <code>glReadPixels</code>, but this will require extra synchronization from your side (otherwise, a thread could be preempted in between making the context current and reading back!), and <code>(wgl|glx)MakeCurrent</code> is a terribly slow function that will seriously stall OpenGL. In the end, you'll be doing <em>more work</em> to get something much <em>slower</em>.</p> <p>There is no way to make <code>glReadPixels</code> any faster¹, but you can decouple the time it takes (i.e. the readback runs asynchronously), so it does not block your application and effectively <em>appears</em> to run "faster".<br> You want to use a <a href="http://www.songho.ca/opengl/gl_pbo.html#pack">Pixel buffer object</a> for that. Be sure to get the buffer flags correct.</p> <p>Note that mapping the buffer to access its contents will <em>still</em> block if the complete contents hasn't finished transferring, so it will <em>still</em> not be any faster. To account for that, you either have to read the previous frame, or use a fence object which you can query to be sure that it's done.<br> Or, simpler but less reliable, you can insert "some other work" in between <code>glReadPixels</code> and accessing the data. This will not guarantee that the transfer has finished by the time you access the data, so it may still block. However, it <em>may</em> just work, and it will <em>likely</em> block for a shorter time (thus run "faster").</p> <p><hr /> ¹ There are plenty of ways of making it <em>slower</em>, e.g. if you ask OpenGL to do some weird conversions or if you use wrong buffer flags. However, generally, there's no way to make it faster since its speed depends on all previous draw commands having finished before the transfer can even start, and the data being transferred over the PCIe bus (which has a fixed time overhead plus a finite bandwidth).<br> The only viable way of making readbacks "faster" is hiding this latency. It's of course still not faster, but you don't get to feel it.</p>

Unit testing Python Flask Stream <p>Does anybody have any experience/pointers on testing a Flask Content Streaming resource? My application uses Redis Pub/Sub, when receiving a message in a channel it streams the text 'data: {"value":42}' The implementation is following Flask docs at: <a href="http://flask.pocoo.org/docs/0.10/patterns/streaming/" rel="nofollow">docs</a> and my unit tests are done following Flask docs too. The messages to Redis pub/sub are sent by a second resource (POST).</p> <p>I'm creating a thread to listen to the stream while I POST on the main application to the resource that publishes to Redis.</p> <p>Although the connection assertions pass (I receive OK 200 and a mimetype 'text/event-stream') the data object is empty.</p> <p>My unit test is like this:</p> <pre><code>def test_04_receiving_events(self): headers = [('Content-Type', 'application/json')] data = json.dumps({"value": 42}) headers.append(('Content-Length', len(data))) def get_stream(): rv_stream = self.app.get('stream/data') rv_stream_object = json.loads(rv_stream.data) #error (empty) self.assertEqual(rv_stream.status_code, 200) self.assertEqual(rv_stream.mimetype, 'text/event-stream') self.assertEqual(rv_stream_object, "data: {'value': 42}") t.stop() threads = [] t = Thread(target=get_stream) threads.append(t) t.start() time.sleep(1) rv_post = self.app.post('/sensor', headers=headers, data=data) threads_done = False while not threads_done: threads_done = True for t in threads: if t.is_alive(): threads_done = False time.sleep(1) </code></pre> <p>The app resource is:</p> <pre><code>@app.route('/stream/data') def stream(): def generate(): pubsub = db.pubsub() pubsub.subscribe('interesting') for event in pubsub.listen(): if event['type'] == 'message': yield 'data: {"value":%s}\n\n' % event['data'] return Response(stream_with_context(generate()), direct_passthrough=True, mimetype='text/event-stream') </code></pre> <p>Any pointers or examples of how to test a Content Stream in Flask?

<p><code>HasColumnType("datetime")</code> specifies the column type, not the temporary parameter types that are used in the SQL statements. You can't control those and it's not necessary. If you have a .NET <code>DateTime</code> in your application with some decimal places filled and want to store that in a <code>datetime</code> type in SQL Server the value will (and can only) be stored as a rounded value. It doesn't matter if the rounding happens on client side before the SQL is sent to the database server or if the rounding happens on the database server itself. The result will be the same: A rounded stored value with a loss of precision.</p>

<p>Relations are defined by predicates in Prolog. There is no built-in (but you could do it for example by using term expansion) syntactic way to define predicates inside predicates in program text, and there seems little reason to do so. You can simply write separate predicates and refer to them. You <em>can</em> of course have nested terms, that is terms as subterms of other terms. </p> <p>What do you mean with</p> <pre><code>relation(CctypeInt,[0-{2,3,4}, 1-{2,3,4}, 2-{2}],Ru1),!. </code></pre> <p>? This is a clause that states something about the predicate (,)/2 , which I doubt was the intention. On the other hand, you can of course build and use a Prolog term like</p> <pre><code>relation(cctypeint,relation(ru_1,...,ru_n)) </code></pre> <p>in your programs to represent your data.</p>

How to find the vertical and horizontal distance from the center of a rectangle <p>For my current Java project I have to compute the horizontal and vertical distance from the center of a rectangle. I tried using the formula from a previous project to find such a distance. Here is my code:</p> <pre><code> // Calculations; centerCoordinate = 0 formula = Math.sqrt(Math.pow(userXCoordinate - centerCoordinate, 2) + Math.pow(userYCoordinate - centerCoordinate, 2)); </code></pre> <p>My professor gave the hint that a point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2. I tried using 5 for horizontal distance and 2.5 for vertical distance and setting variables to these numbers. I then made an if-else loop saying if the result of the formula was less than or equal to the variables the coordinates were in the rectangle otherwise they were outside. This returned a wrong answer; what could I do differently? </p>

Use json-simple (Java, Eclipse) to convert a txt file to JSON file, some special characters does not shown properly in JSON file <p>I am using json-simple to parse a txt file to JSON file. The data I need contains some special characters (emoticon) such as "(●⁰౪⁰●)(//●⁰౪⁰●)//" and " "˭̡̞(◞⁎˃ᆺ˂)◞<em>✰". The result JSON file is not recoginize some characters in it, for instance it will convert the second emoticon into "˭̡̞(◞\u204E˃ᆺ˂)◞</em>✰" I know that \204E is the UTF code for lower * but I do not know how to correctly make it write properly into JSON file. I have tried to encode my input txt file in UTF_8 but it does not work as well. I was wondering if anyone has a good idea for how to solve the issue, Thanks. </p>

<p>Chrome (or any other browser) doesn't support HTAs at all. Actually HTAs are run by mshta.exe, and IE is used as a rendering &amp; scripting engine.</p> <p>When HTA is run with IE9 (<code>&lt;meta http-equiv="x-ua-compatible" content="IE=9"&gt;</code>) there are some issues with <code>&lt;HTA: application&gt;</code>, like some mess with <code>icon</code> and window borders.</p> <p>With IE10 (<code>&lt;meta http-equiv="x-ua-compatible" content="IE=edge"&gt;</code>) it seems, that HTA properties are ignored totally, even <code>singleInstance="yes"</code> doesn't work. If you take a look at a runtime source, you can see the <code>&lt;HTA: application&gt;</code> tag is moved to the <code>body</code>, where it has not the expected influence.</p> <p>All above written about IE is related to the actual HTA properties only, all HTML, scripts and privilegs work well.

Suggestion for solving fragile pattern matching <p>I often need to match a tuple of values that should have the same constructor. The catchall <code>_,_</code> always winds-up at the end. This of course is fragile, any additional constructor added to the type will compile perfectly fine. My current thoughts are to have matches that connect the first but not second argument. But, is there any other options?</p> <p>For example,</p> <pre><code>type data = | States of int array | Chars of (char list) array let median a b = match a,b with | States xs, States ys -&gt; assert( (Array.length xs) = (Array.length ys) ); States (Array.init (Array.length xs) (fun i -&gt; xs.(i) lor ys.(i))) | Chars xs, Chars ys -&gt; assert( (Array.length xs) = (Array.length ys) ); let union c1 c2 = (List.filter (fun x -&gt; not (List.mem x c2)) c1) @ c2 in Chars (Array.init (Array.length xs) (fun i -&gt; union xs.(i) ys.(i))) (* inconsistent pairs of matching *) | Chars _, _ | States _, _ -&gt; assert false </code></pre>

If any of them satisfies the condition then no need to iterate through the remaining garments collection, simple break and come out of the iterator.</p> <p>For comparing the price, I am using , it is present inside the .</p> <p>I am not able to break out from the once the garment price condition is satisfied (i.e. >$1000).</p> <p>Kindly let me know how to break the iteration in struts 1.2.</p> <p>Regards,</p>

JSF 2.0 has Bean Validation (JSR 303) and also its own Validation Framework <p>JSF 2.0 has offered <code>Bean Validation</code> (JSR 303) and its own <code>Validation framework</code>, given the choices, i am confused with which one to choose from. </p> <p>It seems that with JSF's validation framework, i may specify constraints at the XHTML view layer. i.e. max length. While using Bean Validation, i would specify the constraints via annotations (@) in the bean.</p> <p>I see the JSF Validation framework as more of a plug-gable attempt, while the bean validation JSR as an elegant solution, can anyone comment on this?</p> <p>May i check if anyone has used one over another and why, or if anyone has used both together?</p>

How to see output in Amazon EMR/S3? <p>I am new to Amazon Services and tried to run the application in Amazon EMR.</p> <p>For that I have followed the steps as:</p> <p>1) Created the Hive Scripts which contains --> create table, load data statement in Hive with some file and select * from command.</p> <p>2) Created the S3 Bucket. And I load the object into it as: Hive Script, File to load into the table.</p> <p>3) Then Created the Job Flow (Using Sample Hive Program). Given the input, ouput, and script path (like s3n://bucketname/script.q, s3n://bucketname/input.txt, s3n://bucketname/out/). Didn't create out directory. I think it will get created automatically.</p> <p>4) Then Job Flow start to run and after some time I saw the states as STARTING, BOOTSTRAPING, RUNNING, and SHUT DOWN.</p> <p>5) While running SHUT DOWN state, it get terminated automatically showing FAILES status for SHUT DOWN.</p> <p>Then on the S3, I didn't see the out directory. How to see the output? I saw directory like daemons, nodes, etc......</p> <p>And also how to see the data from HDFS in Amazon EMR?</p>

<p>There might be other problems in your snippet, so far I've noticed you're using <code>std::map</code> which is unusual data-structure for this purpose as <code>std::map</code> will overwrite previous <code>nodeId</code> with same <code>weight</code>. You can use <code>std::multimap</code> but you will need some more <code>std::iterator</code> and stuffs for looping on key-value pairs. Use <code>std::priority_queue</code> which will allow you to keep the code precise.</p> <p>Here is a simple snippet solution with <code>std::priority_queue</code> which calculate shortest distance from source to destination node. You can modify or write similarly for your problems:</p> <pre><code>#define Max 20010 // MAX is the maximum nodeID possible vector &lt;pair&lt;int, int&gt;&gt; adj[Max]; // adj[u] contains the adjacent nodes of node u int dis[Max]; // dis[i] is the distance from source to node i priority_queue &lt;pair&lt;int, int&gt;, vector&lt;pair&lt;int, int&gt; &gt;, greater&lt;pair&lt;int, int&gt; &gt; &gt; Q; int dijkstra(int src, int des) { memset(dis, MAX, sizeof dis); Q = priority_queue &lt;pair&lt;int, int&gt;, vector&lt;pair&lt;int, int&gt; &gt;, greater&lt;pair&lt;int, int&gt; &gt; &gt; (); dis[src] = 0; Q.push({dis[src] , src}); while(!Q.empty()) { int u = Q.top().second; Q.pop(); if(u == des) { return dis[des]; } for(int i = 0; i &lt; (int)adj[u].size(); ++i) { int v = adj[u][i].first; int cost = adj[u][i].second; if(dis[v] &gt; dis[u] + cost) { dis[v] = dis[u] + cost; Q.push({dis[v], v)}); } } } return -1; // no path found } </code></pre>

<p>Your function is not "returning" anything. It prints a value to stdout, and each invocation will do that.</p> <p>If you want to simulate a function return with this mechanism, you need to capture and resend the value:</p> <p>Bash functions return an exit status, and this works as you might expect (as long as you expect 0 to be success). If you don't specify otherwise, the return value is that of the last command. So the following would work:</p> <pre><code>tryn() { if (($1 == 0)); then return 2; fi "$@" || tryn $(($1-1)) "$@" } if tryn 2 ping $host; then # success fi </code></pre>

<ul> <li><p>Doing it the way you describe will not do any harm.</p></li> <li><p>You can move the <code>.git</code> directory into the tree you want to commit instead of moving the tree to the repository.</p></li> <li><p>You can use the <code>--work-tree</code> option or <code>GIT_WORK_TREE</code> environment variable to act as if you did that:</p> <pre><code>git add --work-tree=CurrentProduction -A; git commit ... </code></pre> <p>Note that it is not necessary to specify it for commands after <code>add</code> since <code>add</code> copies content into the index, <code>commit</code> uses the index, and the index is in <code>.git</code>.</p></li> </ul> <p>As a separate issue, note that your procedure will make the <code>develop</code> initial commit a child of the <code>master</code> initial commit. That is probably the right thing for this case; I just want to make sure you're aware it's not symmetric.</p>

Adding observer to NSNotificationCenter second time causes EXC_BAD_ACCESS <p>Hypothetical scenario:</p> <p>In my <code>viewDidLoad</code> method I am adding view controller as an observer for custom notification (say, notification <code>MyFooNotification</code>). Later in the process when view is loaded the notification gets posted and controller processes it. When I leave the controller with it's view I DO NOT remove the observer (intentionally) in <code>viewDidUnload</code>. Next time when opening the view, the observer gets added again, but now when the observed notification gets posted - I get <code>EXC_BAD_ACCESS</code>.</p> <p>Can anyone explain why this is happenning.</p> <p>P.S. I do know that I should remove it in <code>viewDidUnload</code> I'm just curious about the lower level details.</p>

<p>Ignoring the fact that <code>eval</code> is probably super dangerous to use here (unless the data in <code>somefile</code> is controlled by you and only you), there are a few issues to fix in your example code.</p> <p>In your <code>for</code> loop, <code>alert_list</code> needs to be <code>$alert_list</code>.</p> <p>Also, as pointed out by @choroba, you should be using <code>!=</code> instead of <code>-ne</code> since your input isn't always an integer.</p> <p>Finally, while debugging, you can add <code>set -x</code> to the top of your script, or add <code>-x</code> to the end of your shebang line to enable verbose output (helps to determine how bash is expanding your variables).</p> <p>This works for me:</p> <pre><code>#!/bin/bash -x data=2.2 version=1 al_ap_version=('ap_version' '[[ $data != $version ]]') alert_list='al_ap_version' for alert in $alert_list; do condition=$(eval echo \${$alert[1]}) if eval "$condition"; then echo "alert" fi done </code></pre>

How to extract the result of a query from JSON inside a custom javascript function in OrientDB <p>I created a custom javascript function in the OrientDB Studio. The function takes a rid as an argument and performs a select query from that rid.</p> <pre><code>var graph = orient.getGraph(); var res = graph.command( "sql", "select outE('Rel').inV('B').size() as lower_num from " + rid ); </code></pre> <p>So, the result of this query is a number. Depending on the value of this number the function should do different things. I wonder how to extract and use that value from the res variable inside the function. All my attempts have failed so far.. If I return the res variable from the function, the result looks like this: </p> <pre><code>[ { "@type": "d", "@rid": "#-2:1", "@version": 0, "lower_num": 2 } ] </code></pre> <p>So, I tried the following <code>( res[0]['lower_num'] == 2 ); ( res['lower_num'] == 2 )</code> and nothing worked.. They always returned false. Any ideas?</p>

<p>Let's start by getting some terminology out of the way</p> <ul> <li>A <em>channel</em> is a monaural stream of samples. The term does not necessarily imply that the samples are contiguous in the data stream. </li> <li>A <em>frame</em> is a set of co-incident samples. For stereo audio (e.g. L &amp; R channels) a frame contains two samples.</li> <li>A <em>packet</em> is 1 or more frames, and is typically the minimun number of frames that can be processed by a system at once. For PCM Audio, a packet often contains 1 frame, but for compressed audio it will be larger. </li> <li><em>Interleaving</em> is a term typically used for stereo audio, in which the data stream consists of consecutive frames of audio. The stream therefore looks like L1R1L2R2L3R3......LnRn</li> </ul> <p>Both big and little endian audio formats exist, and depend on the use-case. However, it's generally ever an issue when exchanging data between systems - you'll always use native byte-order when processing or interfacing with operating system audio components. </p> <p>You don't say whether you're using a little or big endian system, but I suspect it's probably the former. In which case you need to byte-reverse the samples.</p> <p>Although not set in stone, when using floating point samples are usually in the range <code>-1.0&lt;x&lt;+1.0</code>, so you want to divide the samples by <code>1&lt;&lt;15</code>. When 16-bit linear types are used, they are typically signed.</p> <p>Taking care of byte-swapping and format conversions:</p> <pre><code>int s = (int) interleavedData[2 * i]; short revS = (short) (((s &amp; 0xff) &lt;&lt; 8) | ((s &gt;&gt; 8) &amp; 0xff)) left[i] = ((float) revS) / 32767.0f; </code></pre>
