38,737,328 | 0 | <p>I'm afraid this "issue" happens in the Python (instead of pandas) side. When you have some instant values like <code>1234589890878708980.67</code> it's recognized as <code>float</code> and loses precision instantly, e.g.:</p> <pre><code>>>> 1234589890878708980.67 1.234589890878709e+18 >>> 1234589890878708980.67 == 1234589890878708980.6712345 True </code></pre> <p>You might try something like <code>decimal.Decimal</code>:</p> <pre><code>>>> import decimal >>> pd.DataFrame({'x': [decimal.Decimal('1234589890808980.67')]}) x 0 1234589890808980.67 </code></pre> <p><strong>EDITED:</strong></p> <p>OP's added a few questions in the comment.</p> <blockquote> <p>However, do I understand it right that for this method work correctly the value should be string in the first place?</p> </blockquote> <p>Yes :)</p> <blockquote> <p>What if it's float read from csv file?</p> </blockquote> <p>AFAIK Python's <code>csv</code> reader shall not have performed any type conversion, and you'll get strings that could be later converted freely. Otherwise if you're using <code>pandas.read_csv</code>, you could try setting the <code>dtype</code> and <code>float_precision</code> arguments (you could also ask pandas to load plain strings, and have the values converted later yourself).</p> |

7,945,561 | 0 | Beginning Dynamic Programming - Greedy coin change help <p>I am currently working through a book on algorithm design and came across a question whereby you must implement a greedy algorithm with dynamic programming to solve the coin change problem.</p> <p>I was trying to implement this and I just can't figure out out or make sense of the algorithm given in my book. The algorithm is as follows(with my (lack of) understanding in comments) :</p> <pre><code>Change(p) { C[0] = 0 for(i=1 to p) //cycling from 1 to the value of change we want, p min = infinity for(j=1 to k( //cyle from 1 to...? if dj <=i then if(1+C[i-dj] < min) then min = 1+C[i-dj] endif endif endfor C[i] = min endfor return C[p] } </code></pre> <p>And my attempt at interpreting what's going on :</p> <pre><code>/** * * @param d * currency divisions * @param p * target * @return number of coins */ public static int change(int[] d, int p) { int[] tempArray = new int[Integer.MAX_VALUE]; // tempArray to store set // of coins forming // answer for (int i = 1; i <= p; i++) { // cycling up to the wanted value int min = Integer.MAX_VALUE; //assigning current minimum number of coints for (int value : d) {//cycling through possible values if (value < i) { if (1 + tempArray[i - value] < min) { //if current value is less than min min = 1 + tempArray[1 - value];//assign it } } } tempArray[i] = min; //assign min value to array of coins } System.out.println("help"); // :( return tempArray[p]; } </code></pre> <p>Can someone please explain to me what I am missing, how to fix this, and how this algorithm is supposed to work? Dynamic Programming seems like such a useful tool, but I cannot get my head around it. I keep thinking recursively.</p> |

16,792,604 | 0 | <p>There is no need to write <code>new String()</code> to create a new string. When we write <code>var x = 'test';</code> statement, it create the <code>x</code> as a string from a primitive data type. We can't attach the custom properties to this <code>x</code> as we do with object literal. ie. <code>x.custom = 'abc';</code> <code>x.custom</code> will give undefined value. Thus as per our need we need to create the object. <code>new String()</code> will create an object with <code>typeof()</code> Object and not string. We can add custom properties to this object.</p> |

21,186,828 | 0 | Numerous 499 status codes in nginx access log after 75 seconds <p>We are using nginx in a long polling scenario. We have a client that the user installs which then communicates with our server. An nginx process in that server passes that request to backends which are Python processes. The Python process holds the request for up to 650 seconds.</p> <p>In the nginx access log there are a lot of 499 entries. Logging the $request_time shows that the client times out after 75 seconds.

1,752,176 | 0 | <p>Reiterating a few prior posts here (which I'll vote up)...</p> <p>How selective is TypeId? If you only have 5, 10, or even 100 distinct values across your 100M+ rows, the index does nothing for you -- particularly since you're selecting all the rows anyway.</p> <p>I'd suggest creating a column on CHECKSUM(Name) in both tables seems good. Perhaps make this a persisted computed column:</p> <pre><code>CREATE TABLE BioEntity ( BioEntityId int ,Name nvarchar(4000) ,TypeId int ,NameLookup AS checksum(Name) persisted ) </code></pre> <p>and then create an index like so (I'd use clustered, but even nonclustered would help):</p> <pre><code>CREATE clustered INDEX IX_BioEntity__Lookup on BioEntity (NameLookup, TypeId) </code></pre> <p>(Check BOL, there are rules and limitations on building indexes on computed columns that may apply to your environment.)</p> <p>Done on both tables, this should provide a very selective index to support your query if it's revised like this:</p> <pre><code>SELECT EGM.Name, BioEntity.BioEntityId INTO AUX FROM EGM INNER JOIN BioEntity ON EGM.NameLookup = BioEntity.NameLookup and EGM.name = BioEntity.Name and EGM.TypeId = BioEntity.TypeId </code></pre> <p>Depending on many factors it will still run long (not least because you're copying how much data into a new table?) but this should take less than days.</p> |

I spent a long time with the documentation and piecing together bits of code that I found. </p> <pre><code>function stockRun() { var sheet = SpreadsheetApp.getActiveSheet(); var row = 2; while (true) { if (!sheet.getRange(row, 2).getValue()) { var ticker = sheet.getRange(row, 1).getValue(); if (!ticker) break; var stockInfo = FinanceApp.getStockInfo(ticker); sheet.getRange(row, 2).setValue(stockInfo.closeyest); sheet.getRange(row, 3).setValue(stockInfo.priceopen); sheet.getRange(row, 4).setValue(stockInfo.change); sheet.getRange(row, 5).setValue(stockInfo.changepct + "%"); } row++; } } </code></pre> <p>Now that I want historical data, I'm not really sure where to go. I don't understand how I can use the class <a href="https://developers.google.com/apps-script/reference/finance/stock-info-snapshot" rel="nofollow">StockInfoSnapshot[]</a> and use the properties of it.</p> <p>Thanks so much for all your help! I know this must seem so simple, but it's really confusing to me. Once I understand how to use the class I'll be able to work on it and expand my program from there. :)</p> |

18,563,822 | 0 | <p>Your plan sounds good to me except storing keys inside the keystore. Basically, there is only one keystore instance created for all system-level and third-party apps on the device. After Android 4.0, the keystore is integrated with the unlock screen and it is unlocked when the user unlocked the device. So, if you store your key as a key/value pair inside the keystore, then your key is ready before you open your app. Or, if you store it as key/encrypted(value) pair, then you have to derive the key from the password at run-time and decrypt the encrypted value. But you may end up having two password for unlocking the phone screen and unlocking the key. I probably go with with only one password, i.e. screen unlock password. Since the keystore is mapped to the Process ID, it is only accessed from your app. However, if you are thinking to handle multi-user per phone, then the latter approach may be relevant.</p> |

1,632,832 | 0 | <p>C++ does not have a base object that all objects inherit from, unlike Java. The usual approach for what you want to do would be to use <a href="http://www.parashift.com/c++-faq-lite/templates.html" rel="nofollow noreferrer">templates</a>. All the containers in the standard C++ library use this approach. </p> <p>Unlike Java, C++ does not rely on polymorphism/inheritance to implement generic containers. In Java, all objects inherit from <code>Object</code>, and so any class can be inserted into a container that takes an <code>Object</code>. C++ templates, however, are compile time constructs that instruct the compiler to actually generate a different class for each type you use. So, for example, if you have:</p> <pre><code>template <typename T> class MyContainer { ... }; </code></pre> <p>You can then create a <code>MyContainer</code> that takes <code>std::string</code> objects, and another MyContainer that takes <code>int</code>s. </p> <pre><code>MyContainer<std::string> stringContainer; stringContainer.insert("Blah"); MyContainer<int> intContainer; intContainer.insert(3342); </code></pre> |

32,371,116 | 0 | <p>I think its reasonable to say that most algorithms have a best and a worst case. If you think about algorithms in terms of Asymptotic Analysis you can say that a O(n) search algorithm will perform worse than a O(log n) algorithm. However if you provide the O(n) algorithm with data where the search item is early on in the data set and the O(log n) algorithm with data where the search item is in the last node to be found the O(n) will perform faster than the O(log n).</p> <p>However an algorithm that has to examine each of the inputs every time such as an Average algorithm won't have a best/worst as the processing time would be the same no matter the data.</p> <p>If you are unfamiliar with Asymptotic Analysis (AKA big O) I suggest you learn about it to get a better understanding of what you are asking.</p> |

3,666,218 | 0 | <p>I think that in general the topics that you have picked are very important, and my give you the chance to do something more than the usual boring stuff. However, I believe that the order should be something like this:</p> <ol> <li>Data structures & Algorithms</li> <li>Functional programming</li> <li>Software Design </li> <li>Specific technologies you need</li> </ol> <p>My opinion is that Algorithms and data structures should be first. It is very hard to study algorithms if you have a lot of other things in you head (good coding practices, lots of programming paradigms, etc.). Also with time, people tend to become more lazy, and lose the patience to get into the ideas of this complex matter. On the other hand, missing some fundamental understanding about how things can be represented or operate, may lead to serious flaws in understanding anything more sophisticated. So, assuming that you have some ideas about imperative programming (the usual stuff tаught in the introductory courses) you should enhance your knowledge with algorithms and data structures.</p> <p>It is important to have at least basic understanding of other paradigms. Functional programming is a good example. You may also consider getting familiar with logic programming. Having basic understanding of Algorithms and Data Structures will help you a lot in understanding how such languages work. I don't know whether Scala is the best language for that purpose, but will probably do. Alternatively, you can pick something more classic like Lisp, or Scheme. Haskell is also an interesting language.</p> <p>About the Design Patterns... knowing design patterns will help you in doing object oriented design, but you should be aware, that design patterns are just a set of solutions to popular problems. Knowing Design Patterns is by no means that same as knowing how to design software. In order to improve you software design skills you should study other materials too. A good example from where you can get understanding about these concepts is the book Code Complete, or the MIT course 6.170 (its materials are publicly available). </p> <p>At some point you will need to get into the details of a specific framework (or frameworks) that you will need for what you do. Keep in mind, that such frameworks change, and you should be able to adapt, and learn new technologies. For instance, knowing ASP.NET MVC now, may be worthless 5 years from now (or may not be, who knows?).</p> <p>Finally, keep in mind, that no matter what you read, you need to practice a lot, which means solving problems, writing code, designing software, etc. Most of these concepts can not be easily explained, or even expressed with words, so you will need to reach most of them by yourself, (that is, you will need to reinvent the wheel many times). </p> <p>Good luck with your career!</p> |
14,632,866 | 0 | <p>If you want to use it more times in your program then it's maybe a good idea to make a custom class inherited from StreamReader with the ability to skip lines.</p> <p>Something like this could do:</p> <pre><code>class SkippableStreamReader : StreamReader { public SkippableStreamReader(string path) : base(path) { } public void SkipLines(int linecount) { for (int i = 0; i < linecount; i++) { this.ReadLine(); } } } </code></pre> <p>after this you could use the SkippableStreamReader's function to skip lines.

2,616,378 | 0 | can't write to physical drive in win 7? <p>I wrote a disk utility that allowed you to erase whole physical drives. it uses the windows file api, calling :</p> <pre><code>destFile = CreateFile("\\\\.\\PhysicalDrive1", GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING,createflags, NULL); </code></pre> <p>and then just calling <code>WriteFile</code>, and making sure you write in multiples of sectors, i.e. 512 bytes.</p> <p>this worked fine in the past, on XP, and even on the Win7 RC, all you have to do is make sure you are running it as an administrator. </p> <p>but now I have retail Win7 professional, it doesn't work anymore! the drives still open fine for writing, but calling <code>WriteFile</code> on the successfully opened Drive now fails!</p> <p>does anyone know why this might be? could it have something to do with opening it with shared flags? this is always what I have done before, and its worked. could it be that something is now sharing the drive? blocking the writes? is there some way to properly "unmount" a drive, or at least the partitions on it so that I would have exclusive access to it? </p> <p>some other tools that used to work don't any more either, but some do, like the WD Diagnostic's erase functionality. and after it has erased the drive, my tool then works on it too! leading me to believe there is some "unmount" process I need to be doing to the drive first, to free up permission to write to it. </p> <p>Any ideas?</p> <p>Update:</p> <p>the error code returned from <code>WriteFile</code> is '5', <code>ERROR_ACCESS_DENIED</code> but again, if I 'erase' the drive first using WD Diag, I can then access and write to the drive fine. when I initialize the drive again, and give it a partition, I go back to getting the <code>ERROR_ACCESS_DENIED</code> error.</p> |

6,637,497 | 0 | <p>Since <code>Light</code> inherits from <code>Switchable</code>, it could also be deployed with <code>Switchable</code> - it seems, however, due to the naming, that the primary class interacting with the <code>Switchable</code> interface will be <code>Switch</code> - which means that the two are tightly-coupled: you should never put tightly-coupled class/interface definitions in separate assemblies. </p> <p>You could also conceive of other <code>Switchable</code> classes, such as <code>Outlet</code> or a whole set of <code>Appliances</code>. These could be added at a later date, and they would have nothing to do with <code>Light</code>, meaning that <code>Light</code> and <code>Switchable</code> aren't necessarily part of the same component. However, the <code>Switch</code> class would still apply to these new classes and would apply.</p> <p>(It is true that a different consumer of the <code>Switchable</code> interface could be conceived, but it would likely be an awkward adaptation, such as a <code>ToggleButton</code> that toggled the on/off state by remembering the last method called. However, with the names chosen, <code>Switchable</code> still implies that a <code>Switch</code> could be involved.)</p> <p>I hope this answers your question.</p> |

22,244,799 | 0 | <p>This is not a bug in Unity.</p> <p>Something inside the OS is getting into a bad state and the touch-drag messages stop flowing smoothly. Sometimes you'll get multiple updates in a frame and sometimes you'll get none.</p> <p>The issue does not happen on iPhone4 or below, or if the game is running at 30Hz frame rate.</p> <p>I experienced this bug while using an in-house engine I'd written while working at a previous company. It first manifest itself after upgrading the UI system of a scrabble genre game, where you drag the tiles about on the screen. This was utterly bizarre, and I was never able to pin down the exact reproduction steps, but they seem to be timing related, somehow.</p> <p>It can also be seen on Angry Birds (unless they've fixed it by now), and a variety of other games on the market, basically anything with touch-drag scrolling or movement. For Angry Birds, just go into a level and start scrolling sideways. Most of the time it'll be silky smooth, but maybe 1 in 10 times, it'll be clunky. Re-start the app and try again.</p> <p>A workaround is to drop the input update frequency to 30Hz for a few frames. This jolts the internals of the OS somehow and gives it time to straighten itself out, so when you crank it back up to 60Hz, it runs smoothly again.</p> <p>Do that whenever you detect that the bad state has been entered.</p> |

1,918,637 | 0 | Django - Designing Model Relationships - Admin interface and Inline <p>I think my understanding of Django's FK and admin is a bit faulty, so I'd value any input on how to model the below case.</p> <p>Firstly, we have generic Address objects. Then, we have User's, who each have a UserProfile. Through this, Users belong to departments, as well as having addresses.</p> <p>Departments themselves can also have multiple addresses, as well as a head of department. So it might be something like (this is something I'm just hacking up now):</p> <pre><code>class Address(models.Model): street_address = models.CharField(max_length=20) etc... class Department(models.Model): name = models.CharField(max_lenght=20) head_of_department = models.OneToOneField(User) address = models.ForeignKey(Address) class UserProfile(models.Model): user = models.ForeignKey(User, unique=True) address = models.ForeignKey(Address) department = models.OneToOneField(Department) </code></pre> <p>Anyhow, firstly, is that the right way of setting up the relationships?</p> <p>And secondly, I'd like it to appear in the admin that you can edit a department, and on that page, it'd have an inline list of all the addresses to also edit. I've tried setting up an AddressInline class, and attaching it as an inline to Department.</p> <pre><code>class AddressInline(admin.TabularInline): model = Address class DepartmentAdmin(admin.ModelAdmin): inlines = [AddressInline] </code></pre> <p>However, when I try to display that, I get:</p> <pre><code>Exception at /admin/people/department/1/ <class 'people.models.Address'> has no ForeignKey to <class 'people.models.Department'> </code></pre> <p>Cheers, Victor</p> |
18,392,612 | 0 | <p>Let's say RAND_MAX is 150. (Obviously it's not actually.) And we want numbers from 0-99. Then we do <code>rand() % 100</code>. Cool.</p> <p>The problem is, what if RAND() returns a number greater than 100? Let's take 102. <code>102 % 100 = 2</code>, and <code>2 % 100 = 2</code>. So there is a <code>2/150</code> chance that we will get a 2 with the given algorithm. But a number above 50? There's only a <code>1/150</code> chance that we'll get it. The higher RAND_MAX, the less of a problem this is, but it remains an issue. </p> <p>Notice that if RAND_MAX were divisible by the number that you wanted to "modulate" it by, all numbers would be equally likely. i.e if RAND_MAX were 200 rather than 150. Hope this helps!</p> <p>Edit: the actual math.</p> <p>RAND_MAX is guaranteed to be at least 32767. If we want a range from 0-99, we can do <code>RAND() % 100</code>. Then, numbers between 0 and 67 will all appear 328 possible times, while 68-99 will appear only 327 times each. That's a 1.0010071% chance for the first 68 numbers, and only a 0.9979553% chance for the rest of them. We want them all to be 1%! Usually not a major issue, but depending on the use case, could show some strange behavior.</p> |
