Learning scripting/programming (beginning) : <p>What I am asking can be a bit silly and weird by anyway, I decided to ask you.</p>
<p>I am working as network security administrator and have knowledge and experience on cyber security as well. 2 month ago I Started my master degree on Cyber Security and now really want to continue my career on Cyber. Along with network and cyber skills I though having some programming languages in pocket will really benefit me. Shell scripting and Python are the only ones which really catch my interest. </p>
<p>I started with bash scripting and just wrote couple of little scripts. I wonder do you know any source which can I use for exercising. I am usually used to learn when I am actually searching and doing something. Therefore if for instance there is any page where I can find tasks for bash scripts with what I can practice and try do find solution, myself.</p>
<p>Thanks in advance!</p>

laravel orm : How to treat obsessive-compulsive disorder : <p><strong>chinese description：</strong></p>
<p>laravel orm的命名规范对强迫症来说简直是一种灾难，为什么会有这样的设计。。</p>
<p>数据库字段设计成小写字母+下划线，例如order_item表中有个字段goods_name</p>
<p>那么laravel代码中，就得这样写：$orderItem->goods_name</p>
<p>驼峰和全小写混合，强迫症表示实在受不了啊。。。受不了。。。受不了。。。</p>
<p><strong>english description：</strong>
for example: I have a table named order_item and the table have a column named goods_name
in laravel orm I will write code such as: $orderItem->goods_name</p>
<p>the hump naming with the whole lower case，，，，</p>
<p>why why why</p>
<p>why the laravel design so。why not design like：$orderItem->goodsName</p>
<p>I am going nuts.</p>

Create a diffrent table in html : I want to create a table with less rows but with large columns where every 4th column right boundary is 2times thick of other boundary.
Example:
```
| | | | || | | | || | | | || | | | ||
| | | | || | | | || | | | || | | | ||
| | | | || | | | || | | | || | | | ||
```
consider "||" as double width of "|"

Background color and scroll issue. : <p>I need some help here. My final project is due tomorrow and the mobile responsive view of the app is completely off. I don't know how else to explain it other than just giving you the link to the URL. </p>
<p><a href="https://venpresath.github.io/FinalProject/#!/home" rel="nofollow noreferrer">https://venpresath.github.io/FinalProject/#!/home</a></p>
<p>It appears that the animation that I put onto the spinning record is making the width of the screen larger than the background is. </p>
<p>I tried overflow: Hidden; but it didn't correct the issue. </p>

Why wont this work ? Dynamic memory beginner program : enter code here
int main()
{
//FILE *out = fopen("keimeno.txt", "w+");
FILE *in = fopen("keimeno.txt", "r");
int fullbufflen=0 , i;
char buffer[100];
fgets(buffer, 100, in);
int bufflen = strlen(buffer);
char *text;
text =calloc(bufflen,sizeof(char));
char *strcat(text, buffer);
// printf("line of \"keimeno.txt\": %s", buffer);
// printf("size of line \"keimeno.txt\": %i\n\n", bufflen);
fullbufflen = bufflen;
while(fgets(buffer, 100, in)!=NULL)
{
// printf("line of \"keimeno.txt\": %s", buffer);
// printf("size of line \"keimeno.txt\": %i\n\n", bufflen);
text =realloc(text,bufflen*sizeof(char));
char *strcat(text, buffer);
fullbufflen = bufflen + fullbufflen ;
}
for (i = 0;i<fullbufflen;i++)
{
printf("%c\n",text[i]);
}
}
I am trying to copy the full text file (keimeno.txt) into a dynamic memory array,with a buffer of 100 character at most everytime .To test it at the end i tried to prinf the results .And i just cant get it to work .Dont know if there is a problem on the printf at the end,or the whole program is just wrong.(also the dynamic array is supposed to have 0 size at the beggining ,so if someone could tell me how to do that too ,it would be welcome .)Thanks in advance.

How to implement a deep bidirectional LSTM with Keras? : <p>I am trying to implement a LSTM based speech recognizer. So far I could set up bidirectional LSTM (i think it is working as a bidirectional LSTM) by following the example in Merge layer. Now I want to try it with another bidirectional LSTM layer, which make it a deep bidirectional LSTM. But I am unable to figure out how to connect the output of the previously merged two layers into a second set of LSTM layers. I don't know whether it is possible with Keras. Hope someone can help me with this.</p>
<p>Code for my single layer bidirectional LSTM is as follows</p>
<pre><code>left = Sequential()
left.add(LSTM(output_dim=hidden_units, init='uniform', inner_init='uniform',
forget_bias_init='one', return_sequences=True, activation='tanh',
inner_activation='sigmoid', input_shape=(99, 13)))
right = Sequential()
right.add(LSTM(output_dim=hidden_units, init='uniform', inner_init='uniform',
forget_bias_init='one', return_sequences=True, activation='tanh',
inner_activation='sigmoid', input_shape=(99, 13), go_backwards=True))
model = Sequential()
model.add(Merge([left, right], mode='sum'))
model.add(TimeDistributedDense(nb_classes))
model.add(Activation('softmax'))
sgd = SGD(lr=0.1, decay=1e-5, momentum=0.9, nesterov=True)
model.compile(loss='categorical_crossentropy', optimizer=sgd)
print("Train...")
model.fit([X_train, X_train], Y_train, batch_size=1, nb_epoch=nb_epoches, validation_data=([X_test, X_test], Y_test), verbose=1, show_accuracy=True)
</code></pre>
<p>Dimensions of my x and y values are as follows.</p>

Working in Eclipse IDE, values that should equal not equal : <p>I am reasonably experienced with programming, but not specifically in Java. I am coming across the following error when working in eclipse. My code is the following:</p>
<p><a href="https://i.stack.imgur.com/5gqc3.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5gqc3.png" alt="My code"></a></p>
<p>I have used the debug function, and it reports that carbonPrefix is pent, but that carbon stays at 0 throughout. Like I said, I am a novice to Java and Eclipse, so I may not be using the debug function to it's full extent. </p>
<p>For anybody that's interested, this the start of code where you input the name of an alkane and it tells you the formula. It worked in Javascript and I'm just trying to translate it into Java.</p>
<p>Thank you all so much!</p>

dplyr mutate/transmute: drop only the columns used in the formula : <p>Suppose my data frame has columns A, B, C, D, E.</p>
<p>I want to produce a data frame with columns A, B, C, X, where X = D * E.</p>
<p>Obviously I can use <code>%>% mutate(X = D * E) %>% select (-D, -E)</code>, but for more elaborate situations, is there a way to do it in a single command? Like <code>transmute()</code>, but only discarding the columns that were mentioned.</p>
<p>Silly, but I keep wishing for this bit of conciseness.</p>

<p>I repeated the steps again and again, but it's not working. I'm pretty new to this webpack thing, so I'm not able to find out what the problem really is, and what kind of absolute path it requires. I also tried an absolute path suggested by some answer to another (similar) question, but that didn't work.</p>

whois lookup shows correct ip but why my browser cant find ip of domain? : I am facing very strange situation.
my website suddenly stooped working.
when i search for the domain name in WHOIS websites its showing the correct server ip address and correct DNS IP address.
I can reach the website by its IP address but somehow when i am trying domain name in browser its not working and its showing "This site can’t be reached"!!
There is no error in my server log.
I tried different browser and different system and its same issue.
I am really confused. even when i am sending GET request with Postman to my domain it not reachable but sending request to IP is working!

Single instance of class in Python : <p>I am creating a Python application that includes socket communication with a server. I would like to have a module which can be used throughout my entire application (several other modules). Currently my module look like this:</p>
<pre><code>class SocketCommunication:
def __init__(self):
self.socketIO = SocketIO(settings.ADDRESS, settings.PORT, Namespace)
def emit(self, message, data):
json_data = json.dumps(data.__dict__)
self.socketIO.emit(message, json_data)
class Namespace(BaseNamespace):
def on_connect(self):
print '[Connected]'
def on_disconnect(self):
print "[Disconnected]"
</code></pre>
<p>When I use this in other modules I do the following:</p>
<pre><code>import SocketCommunication
self.sc = SocketCommunication()
</code></pre>
<p>The problem is that every time I do this, a new connection is created which will be displayed as a new client on the server, and that is undesirable.
From what I can read, Singletons should be avoided in Python and therefore I am curious about what is best practice for this type of problem? </p>

How can I extract date from since time component : <p>I have to extract date in the format MM-dd-yyyy in java from the since time value. Since time is the time at which the doucment is created. For example, if since time is <strong>1452413972759</strong>, date would be "<strong>Sun, 10 Jan 2016 08:19:32 GMT</strong>" (Calculated from <a href="http://www.epochconverter.com/" rel="nofollow">http://www.epochconverter.com/</a>) . From this, I could get date in desired format but I am unable to code for the first step i.e., converting since time to date. Can someone help me?</p>

<pre><code>DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
java.util.Date date = df.parse("1452320105343");
String DATE_FORMAT = "MM/dd/yyyy";
SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT);
System.out.println("Today is " + sdf.format(date));

How do I pass an expression as a function keyword in Python : <p>I am trying to be pythonic with my code but can't figure out how to do:</p>
<pre><code>dfSort.assign(i+5=pd.Series(dfWork))
</code></pre>
<p>where dfSort is a Dataframe and pd is pandas import. Of course the <code>i+5</code> is an expression and therefore cannot be passed as a column name. But I want to assign a column name dynamically in code (called <code>i+5</code>). The only way to do this otherwise is (this can get cumbersome):</p>
<pre><code>if (i+5)== 5:
dfSort = dfSort.assign(a=pd.Series(dfWork, index=dfSort.index.values))
elif (i+5)==6:
dfSort = dfSort.assign(b=pd.Series(dfWork, index=dfSort.index.values))
elif (i+5)==7:
dfSort = dfSort.assign(c=pd.Series(dfWork, index=dfSort.index.values))
elif (i+5)==8:
dfSort = dfSort.assign(d=pd.Series(dfWork, index=dfSort.index.values))
</code></pre>
<p>Is there a way to do this like the first code block without the if statements?</p>
<p>This doesn't work:</p>
<pre><code>Colname = {5: 'a',6 : 'b', 7 : 'c', 8 : 'd'}
dfSort = dfSort.assign(Colname[i+5]=pd.Series(dfWork) )

How to generate Signature in AWS from Java : <p>When I invoke API endpoints from REST client, I got error by concerning with Signature.</p>
<p>Request:</p>
<blockquote>
<p><strong>Host</strong>: <a href="https://xxx.execute-api.ap-southeast-1.amazonaws.com/latest/api/name" rel="noreferrer">https://xxx.execute-api.ap-southeast-1.amazonaws.com/latest/api/name</a></p>

<p><strong>X-Amz-Date</strong>: 20160314T102915Z</p>
</blockquote>
<p>Response:</p>
<pre><code>{
"message": "The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details. The Canonical String for this request should have been 'xxx' "
}
</code></pre>
<p>From Java code, I followed AWS reference of how to generate Signature.</p>
<pre><code> String secretKey = "{mysecretkey}";
String dateStamp = "20160314";
String regionName = "ap-southeast-1";
String serviceName = "execute-api";
byte[] signature = getSignatureKey(secretKey, dateStamp, regionName, serviceName);
System.out.println("Signature : " + Hex.encodeHexString(signature));
static byte[] HmacSHA256(String data, byte[] key) throws Exception {
String algorithm="HmacSHA256";
Mac mac = Mac.getInstance(algorithm);
mac.init(new SecretKeySpec(key, algorithm));
return mac.doFinal(data.getBytes("UTF8"));
}
static byte[] getSignatureKey(String key, String dateStamp, String regionName, String serviceName) throws Exception {
byte[] kSecret = ("AWS4" + key).getBytes("UTF8");
byte[] kDate = HmacSHA256(dateStamp, kSecret);

byte[] kService = HmacSHA256(serviceName, kRegion);
byte[] kSigning = HmacSHA256("aws4_request", kService);
return kSigning;
}
</code></pre>
<p>May I know what I was wrong while generating Signature?</p>

Questions needs to asked before we need upgrade TFS 2013 upgrade to TFS 2018 upgrade? : One of our client wants to move from TFS 2013 to TFS 2018. We don't have much information about the current TFS setup at client's end.
Can anyone please guide with what questions we need to ask to client to get the information regarding the current TFS setup system before we start with upgrade process.
Also share if there is any process document regarding upgrading the TFS 2013 to TFS 2018.
Thanks in advance.

I am learning Angular js an type script
[When i move my cursor to the The Goal that red lined it shows this: Type '{ id: number; name: string; }[]' is missing the following properties from type 'Goal': id, name][1]
Visual studio shows a red line on Goal saying this: Type '{ id: number; name: string; }[]' is missing the following properties from type 'Goal': id, name
Can any coder show me exactly what to do?

Serving mp3 files using the webpack file loader : <p>I have a problem with getting my mp3 files to work using the webpack file loader.</p>
<p>This is the issue:</p>
<p>I have a mp3 file on my harddisk, that if I open using chrome by for example "c:\somefolder\somemp3file.mp3" opens up in a tab in the browser and plays just fine.</p>
<p>However, when I serve the exact same file using webpack it does not work. I have configured the loader in webpack like this:</p>
<pre><code>{
test: /\.(gif|jpg|png|mp3|aac|ogg)$/,
loader: 'file'
}
</code></pre>
<p>Then, when I'm trying to link to the file I require it inside my javascript, like this:</p>
<pre><code>require('file!./../content/somemp3file.mp3');
</code></pre>
<p>this correctly returns me the url for the mp3 file.</p>
<p>If I try to manually go to <code>localhost:8080</code> followed by the url returned by require, the mp3 player in Chrome pops up like I expect it to, but the file cannot be played, and it's not possible to click on the play button like the file is corrupted or something. </p>
<p>Anyone knows what I'm doing wrong here?</p>

download file 1Gb : I am having difficulty downloading files with a size of 1 GB.
Smaller files works fine.
I've tried some options.
My file is a zip folder that contais some pdf files.
I've tried some options like use WebClient namespace
This is my code that works just smaller files.
byte[] fileBytes = System.IO.File.ReadAllBytes(sPath);
string fileName = System.IO.Path.GetFileName(sPath);
return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
my fileBytes variable stay like this = byte[1099288209] and I get a "Overflow or underflow in the arithmetic operation."
But when my file has 1Gb size or greater it isn't works.
If a use the WebClient namespace I have the follow error:
wClient.DownloadFile("https://site/folder/", sPath);
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.127.1.180:8080"
my fileBytes variable stay like this = byte[1099288209] and I get a "Overflow or underflow in the arithmetic operation."
Using webClient I get an error like this "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.127.1.180:8080"
