I’m not giving you a working solution but just a hint: The JPEG format consists of different parts, some are required and some are optional. Among those optional parts, some allow to store arbitrary data. If you manage to alter such a part of an existing JPEG image or to add one and put your … Read more
As an academic exercise (can it be done vs. should it be done), I came up with this: func isOptional(a: Any) -> Bool { return “\(a.dynamicType)”.hasPrefix(“Swift.Optional”) } Example: let name = “Fred” let oname: String? = “Jones” let age = 37 let oage: Int? = 38 let arr: [Any] = [name, oname, age, oage] for … Read more
There are several ways to transform this variable. In the picture I see, that there are not only bins, but also value ’55+’, it needs to be considered. 1) One liner: df[‘age’].apply(lambda x: np.mean([int(x.split(‘-‘)[0]), int(x.split(‘-‘)[1])]) if ‘+’ not in x else x[:-1]) It checks whether the value contains ‘+’ (like 55+), if yes than the … Read more
First of all, the TSS is a historical wart. Once in a time (a.k.a: early 1980’s), people at Intel tought that hardware context-switching, instead of software context-switching, was a great idea. They were greatly wrong. Hardware context-switching has several noticeable disadvantages, and, as it was never implemented appropiately, had miserable performance. No sane OS even … Read more
Please add more code and explain your question. A general answer to this question: for (int i = 0; i < action.RecordsCount(); i++) { RetrievalRecord uiRecord = action.GetRecord(i); Action_v_Record dbRecord = uiRecord.DataRecord as Action_v_Record; CheckboxRetrievalCell missingcell = uiRecord.GetCell(action.missingAction) as CheckboxRetrievalCell; CheckboxRetrievalCell irrelevantCell = uiRecord.GetCell(action.irrelevantAction) as CheckboxRetrievalCell; int missingCellValue = missingcell.ToInteger; int irrelevantCellValue = irrelevantCell.ToInteger; dbRecord.Missing.NewValue … Read more
Anaconda is only capable of detecting and managing packages within its own environment. It cannot and will not detect and use an existing CUDA installation when installing packages with a CUDA dependency. Note however that the cudatoolkit package which conda will install is not a complete CUDA toolkit distribution. It only contains the necessary libraries … Read more
why here vector <int> :: iterator i; The vector <int> :: iterator i; is created in order to traverse the vector vector <int> g1; (actually it can traverse any vector<int>, but in this case, that’s for g1) is there a difference between vector <int> :: iterator i; and int i? The scope of vector <int> … Read more
The event loop predates javascript.. but just by a tiny bit. The event loop was introduced to support progressive download of pictures in Netscape. And almost immediately it was also used to support early rendering where DOM elements are displayed on screen before all images are downloaded. At the time, other browsers displayed blank white … Read more
You are using equals method with your custom object Student. You need to override it in your Student class. In your case, if you want to match all fields of s1 to s2, your implementation should go like this: //Overriding equals public boolean equals(Object obj) { if (this == obj) return true; if (obj == … Read more
You may use below list comprehension using map with eval(…) as: import ast Users = [‘Protein(“SAHDSJDSFJH”), {“id”: “s1”}’, ‘Protein(“ACGTWZJSFNM”), {“id”: “s2”}’, ‘Protein(“ABHZZEQTAAB”), {“id”: “s3”}’] new_list = [y for x in map(eval, Users) for y in x] where new_list will hold the value: [Protein(“SAHDSJDSFJH”), {‘id’: ‘s1’}, Protein(“ACGTWZJSFNM”), {‘id’: ‘s2’}, Protein(“ABHZZEQTAAB”), {‘id’: ‘s3’}] PS: Note that there … Read more
For your question recently closed: https://stackoverflow.com/questions/34106770/send-email-using-php-from-address-not-working Try this: $headers .= “From: Your Name <$from>\r\n”; and you can also add the 5th mail parameter: mail($to, $subject, $body, $headers, ‘[email protected]’). Works for me with these headers: $from = “$name <$email>\r\n”; $to = “$username <$useremail>\r\n”; $headers=”MIME-Version: 1.0″ . “\r\n”; $headers .= ‘Content-type: text/html; charset=utf-8’ . “\r\n”; $headers .= … Read more
You’re printing the output before you check whether or not you want to print the output. Swap the logic: if (num== 5 || num== 2 || num==3) { continue; } printf(“The num %d is available\n”, num); Or, conversely you can omit the continue: if (num != 5 && num != 2 && num != 3) … Read more
Here is some code to try: File f = new File(filePathString); if(!f.exists() && !f.isDirectory()) { startDownload(); readFile(); } else { try { file.delete(); } catch (Exception e) { e.printStackTrace(); } } solved Android java: how to use if-then-else
To create an Exception in Java, you could do something like this: class GameException extends Exception { GameException() { super(); } GameException(String msg) { super(msg); } GameException(String msg, Throwable cause) { super(msg, cause); } GameException(Throwable cause) { super(cause); } } To use this Exception, you can do the following: if(!checkNumbers(num1, num2)) throw new GameException(); Where … Read more
Yes, You can use two different view in SELECT query. You have to JOIN them, if them have matched column in each other. Just treat two different views as like two different tables when using in SELECT Clause. SELECT vw1.a, vw2.b FROM View1 vw1 INNER JOIN View2 vw2 ON vw1.id = vw2.id For Clarification, A … Read more
