  • How do you avoid jumping to a solution when under pressure? [closed]

    - by GlenPeterson
    When under a particularly strict programming deadline (like an hour), if I panic at all, my tendency is to jump into coding without a real plan and hope I figure it out as I go along. Given enough time, this can work, but in an interview it's been pretty unsuccessful, if not downright counter-productive. I'm not always comfortable sitting there thinking while the clock ticks away. Is there a checklist or are there techniques to recognize when you understand the problem well enough to start coding? Maybe don't touch the keyboard for the first 5-10 minutes of the problem? At what point do you give up and code a brute-force solution with the hope of reasoning out a better solution later? A related follow-up question might be, "How do you ensure that you are solving the right problem?" Or "When is it most productive to think and design more vs. code some experiments to and figure out the design later?" EDIT: One close vote already, but I'm not sure why. I wrote this in the first person, but I doubt I'm the only programmer to ever choke in an interview. Here is a list of techniques for taking a math test and another for taking an oral exam. Maybe I'm not expressing myself well, but I'm asking if there is a similar list of techniques for handling a programming problem under pressure?

  • Calling methods on Objects

    - by Mashael
    Let's say we have a class called 'Automobile' and we have an instance of that class called 'myCar'. I would like to ask why do we need to put the values that our methods return in a variable for the object? Why just don't we call the method? For example: Why should we write: string message = myCar.SpeedMessage(); Console.WriteLine(message); instead of: Console.WriteLine(myCar.SpeedMessage());

  • Unit-Testing functions which have parameters of classes where source code is not accessible

    - by McMannus
    Relating to this question, I have another question regarding unit testing functions in the utility classes: Assume you have function signatures like this: public function void doSomething(InternalClass obj, InternalElement element) where InternalClass and InternalElement are both Classes which source code are not available, because they are hidden in the API. Additionally, doSomething only operates on obj and element. I thought about mocking those classes away but this option is not possible due to the fact that they do not implement an interface at all which I could use for my Mocking classes. However, I need to fill obj with defined data to test doSomething. How can this problem be solved?

  • Persisting NLP parsed data

    - by tjb1982
    I've recently started experimenting with NLP using Stanford's CoreNLP, and I'm wondering what are some of the standard ways to store NLP parsed data for something like a text mining application? One way I thought might be interesting is to store the children as an adjacency list and make good use of recursive queries (postgres supports this and I've found it works really well). Something like this: Component ( id, POS, parent_id ) Word ( id, raw, lemma, POS, NER ) CW_Map ( component_id, word_id, position int ) But I assume there are probably many standard ways to do this depending on what kind of analysis is being done that have been adopted by people working in the field over the years. So what are the standard persistence strategies for NLP parsed data and how are they used?

  • How to display values from another website to an new html page?

    - by user3098728
    How to display the value in a new html file from different website? This an example field of values that need to display into new html file and I want to display the said values in the input box (Contract ID) of this page JSFiddle. I have 2 JS code that would display that values, but unfortunately its not working and I dont know how to display that value in html input box. Please help me. Thank you I want to display the said value in this input box: Here the JS file to read the values: function scanLapVerification() { try { var page_title = "Title"; var el = getElement(document, "class", "view-operator-verification-title", ""); if (!el || el.length == 0) return; if (el[0].innerText != page_title) return; var page_title = ''; var el = getElement(document, "class", "workflowActivityDetailPanel", ""); if (el && el.length > 0) { var eltr = getElement(el[0], "tag", "tr", ""); if (eltr && eltr.length > 0) { //Read Contract ID var contractId = { CI: { id: null } }; var con_id = null; for (var i = 0; i < eltr.length; i++) { tr_text = eltr[i].innerText; if (tr_text.substr(0, "Contract ID".length) == "Contract ID") con_id = "CI"; if (con_id && tr_text.substr(0, "Contract ID".length) == "Contract ID") { contractId[con_id].id = tr_text.substr("Contract ID".length + 1, tr_text.length - "Contract ID".length - 1); } } var contract_id = contractId.CI.id; return { content: "cid_check", con_id: con_id }; } return { status: "KO" }; } catch (e) { alert("Exception: scanLapVerification\n" + e.Description); return { status: "KO", message: e }; } }; And here's the 2nd JS that display to a new html page: function scanLapVerification() { chrome.tabs.sendRequest(tabLapVerification, { method: "scanLapVerification" }, function (response) { msgbox("receiveResponse: scanLapVerification " + jsonToString(response, "JSON")); //maintaining state in the background if (response.data.content == "cid_check") { //Popup window features var popupWindow = null; var name; var width = 550; var height = 200; var left = parseInt((screen.availWidth / 2) - (width / 2)); var top = parseInt((screen.availHeight / 2) - (height / 2)); var windowFeatures = "width=" + width + ",height=" + height + ",left=" + left + ",top=" + top + "screenX=" + left + ",screenY=" + top; //Input new address with popup window if (confirm("Does the client has new address?") == true) { popupWindow = window.open('/htmlname.htm', "title", windowFeatures + encodeURIComponent(response.data.contract_id)); popupWindow.focus(); } else { name = ""; } }); }

  • How can you get constructive criticism for your code?

    - by burnt1ce
    My team rarely does code review, mainly because we don't have enough time and people lack the energy and will to do so. But I would really like to know what people think about my code when they read it. This way, I have a better understanding how other people think and tailor my code accordingly so it's easier to read. So my question is, how can I get constructive criticism for my code? My intent is to understand how people think so I can write more readable code.

  • Is it possible to build a single game to run in Facebook & Google+?

    - by Songo
    I was asked by my customer to build a Facebook game. The game would be something similar to Mafiawars.com where the game is hosted on a server and run through a frame on Facebook. The thing is after several days of negotiations with the customer and near the finalization of the requirements he mentioned something strange. He said that if the game was successful on Facebook then we may add it to Google+ too. I thought he meant that we'll develop a new version for Google+, but he refused as he argued that the game should be able to support both sites and he won't pay for the same game twice. Now I haven't developed neither Facebook nor Google+ games before, so I don't know if it is possible to build a single Facebook/Google+ game. How would you react to such requirement? How would you design such an application? Notes I confirmed with the customer that he wasn't talking about using Open ID he wanted full integration (sharing post, friend requests,..etc.) I really don't want to lose that customer for numerous reasons (He even agreed to extend the project time to compensate for the time I need to learn Facebook/Google+ APIs)

  • A big flat text file or a HTML site for language documentation?

    - by Bad Sector
    A project of mine is a small embeddable Tcl-like scripting language, LIL. While i'm mostly making it for my own use, i think it is interesting enough for others to use, so i want it to have a nice (but not very "wordy") documentation. So far i'm using a single flat readme.txt file. It explains the language's syntax, features, standard functions, how to use the C API, etc. Also it is easy to scan and read in almost every environment out there, from basic text-only terminals to full-fledged high-end graphical desktop environments. However, while i tried to keep things nicely formatted (as much as this is possible in plain text), i still think that being a big (and growing) wall of text, it isn't as easy on the eyes as it could be. Also i feel that sometimes i'm not writing as much as i want in order to avoid expanding the text too much. So i thought i could use another project of mine, QuHelp, which is basically a help site generator for sites like this one with a sidebar that provides a tree of topics/subtopics and offline full text search. With this i can use HTML to format the documentation and if i use QuHelp for some other project that uses LIL, i can import LIL's documentation as part of the other project's documentation. However converting the existing documentation to QuHelp/HTML isn't a small task, especially when it comes to functions (i'll need to put more detail on them than what currently exists in the readme.txt file). Also it loses the wide range of availability that it currently has (even if QuHelp's generated code degrades gracefully down to console-only web browsers, plain text is readable from everywhere, including from popular editors such as Vim and Emacs - i had someone once telling me that he likes LIL's documentation because it is readable without leaving his editor). So, my question is simply this: should i keep the documentation as it is now in the form of a single readme.txt file or should i convert it to something like the site i mentioned above? There is also the option to do both, but i'm not sure if i'll be able to always keep them in sync or if it is worth the effort. After asking around in IRC i've got mixed answers: some liked the wide availability of the single text file, others said that it is looks as bad as a man page (personally i don't mind that - i can read man pages just fine - but other people might have issues reading them). What do you think?

  • How do I improve my code reading skills

    - by Andrew
    Well the question is in the title - how do I improve my code reading skills. The software/hardware environment I currently do development in is quite slow with respect to compilation times and time it takes the whole system to test. The system is quite old/complex and thus splitting it into a several smaller, more manageable sub-projects is not feasible in a neare future. I have realized is what really hinders the development progress is my code reading skills. How do I improve my code reading skills, so I can spot most of the errors and issues in the code even before I hit the "do compile" key, even before I start the debugger?

  • What are the most commonly used enterprise Java technologies, and what would you want a non technical audience to understand about them?

    - by overstood
    I have been asked to give a presentation to a non-technical audience on what Java technologies are currently being used in the enterprise world. The goal is to give this non-technical audience the background they need to understand what engineers are talking about. It's part of a broader series of talks that I'm giving. I'm primarily a .NET and C++ dev, so I thought I'd try to get some input from some Java devs. What technologies do you use? What Java related acronyms would you like to be able to use around non-coders? What would you like non-coders to understand about them?

  • Is there any one standard framework for developing Python GUI apps.?

    - by RPK
    There are so many frameworks for writing GUI application using Python. But is there any one key standard framework? For example we have a bundle of .NET/C# on Visual Studio. I am thinking in other perspectives also. In future if I give an interview for a Python programmer job, which GUI framework will be considered? I also wonder, there is no IDE that integrates the GUI and Python language. Choice of flavor is good but over-choice becomes a distraction.

  • Is browser fingerprinting a viable technique for identifying anonymous users?

    - by SMrF
    Is browser fingerprinting a sufficient method for uniquely identifying anonymous users? What if you incorporate biometric data like mouse gestures or typing patterns? The other day I ran into the Panopticlick experiment EFF is running on browser fingerprints. Of course I immediately thought of the privacy repercussions and how it could be used for evil. But on the other hand, this could be used for great good and, at the very least, it's a tempting problem to work on. While researching the topic I found a few companies using browser fingerprinting to attack fraud. And after sending out a few emails I can confirm at least one major dating site is using browser fingerprinting as but one mechanism to detect fake accounts. (Note: They have found it's not unique enough to act as an identity when scaling up to millions of users. But, my programmer brain doesn't want to believe them). Here is one company using browser fingerprints for fraud detection and prevention: http://www.bluecava.com/ Here is a pretty comprehensive list of stuff you can use as unique identifiers in a browser: http://browserspy.dk/

  • What is the best way to go about testing that we handle failures appropriately?

    - by Earlz
    we're working on error handling in an application. We try to have fairly good automated test coverage. One big problem though is that we don't really know of a way to test some of our error handling. For instance, we need to test that whenever there is an uncaught exception, a message is sent to our server with exception information. The big problem with this is that we strive to never have an uncaught exception(and instead have descriptive error messages). So, how do we test something what we never want to actually happen?

  • JSP Include: one large bean or bean for each include

    - by shylynx
    I want to refactor a webapp that consists of very distorted JSPs and servlets. Because we can't switch to a web framework easily we have to keep JSPs and Servlets, and now we are in doubt how to include pages into another and how to setup the use:bean-directives effectively. At the first step we want to decouple the code for the core-actions and the bean-creation into servlets. The servlets should forward to their corresponding pages, which should use the bean. The problem here is, that each jsp consists of different sub- and sub-sub-jsp that are included into another. Here is a shortend extract (because reality is more complex): head header top navigation actionspanel main header actionspanel foot footer Moreover each jsp (also the header and footer) use dynamic data. For example title and actionspanel can change on each page-reload or do have links and labels that depend on the processing by the preceding servlet. I know that jsp-include-directives should only be used for static content und should be avoided for dynamic content. But here we have very large pages, that consist of many parts. Now the core questions: Should I use one big bean for each page, so that each bean holds also data for header and footer beside its core data, so that each subsequent included jsp uses the same bean-directive? For example: DirectoryJSP <- DirectoryBean CompareJSP <- CompareBean Or should I use one bean for each jsp, so that each bean only holds the data for one jsp and its own purpose. For example: DirectoryJSP <- DirectoryBean HeaderJSP <- HeaderBean FooterJSP <- FooterBean CompareJSP <- CompareBean HeaderJSP <- HeaderBean FooterJSP <- FooterBean In the second case: should the subsequent beans be a member of the corresponding parent bean, so that only the parent bean is attached as attribute to the request? Or should each bean attached to the request?

  • Why learning new things is not important on a job hunt? [closed]

    - by IAdapter
    I have just finished my job hunt. I think it was about 40 job interviews, I like to travel and get to know many companies. One thing I did not like is that they don't care about new technologies. I think only 2 persons asked me about new stuff in Java world. Most of them care if I know Java (certification and many years of experiance is not enough for them, they need to test me) For example in IBM they only cared what IBM products do I know. Have I ever used any custom extensions of WebSphere? I don't understand those questions. If I learn new frameworks every day then I can learn whatever technology they have very fast. So why it matters if I have ever used those "great" custom extensions of WebSphere? After those 40 interviews I have no reason to learn any new framework, because I see that they don't care. Why those "developers" don't ask questions about new technologies? are they so long at those comapnies that they don't care about new stuff?

  • Diff annotation tool

    - by l0b0
    Among the 11 proven practices for more effective, efficient peer code review, diff annotation seems to be the one particularly well suited to tool assistance. The article is written by the architect of SmartBear's CodeCollaborator, so he of course recommends using that. Does anyone know of any alternatives? I can't think of anything that would be even close to paper+pen+marker in pure developer efficiency when it comes to explaining a piece of code.

  • Removing hard-coded values and defensive design vs YAGNI

    - by Ben Scott
    First a bit of background. I'm coding a lookup from Age - Rate. There are 7 age brackets so the lookup table is 3 columns (From|To|Rate) with 7 rows. The values rarely change - they are legislated rates (first and third columns) that have stayed the same for 3 years. I figured that the easiest way to store this table without hard-coding it is in the database in a global configuration table, as a single text value containing a CSV (so "65,69,0.05,70,74,0.06" is how the 65-69 and 70-74 tiers would be stored). Relatively easy to parse then use. Then I realised that to implement this I would have to create a new table, a repository to wrap around it, data layer tests for the repo, unit tests around the code that unflattens the CSV into the table, and tests around the lookup itself. The only benefit of all this work is avoiding hard-coding the lookup table. When talking to the users (who currently use the lookup table directly - by looking at a hard copy) the opinion is pretty much that "the rates never change." Obviously that isn't actually correct - the rates were only created three years ago and in the past things that "never change" have had a habit of changing - so for me to defensively program this I definitely shouldn't store the lookup table in the application. Except when I think YAGNI. The feature I am implementing doesn't specify that the rates will change. If the rates do change, they will still change so rarely that maintenance isn't even a consideration, and the feature isn't actually critical enough that anything would be affected if there was a delay between the rate change and the updated application. I've pretty much decided that nothing of value will be lost if I hard-code the lookup, and I'm not too concerned about my approach to this particular feature. My question is, as a professional have I properly justified that decision? Hard-coding values is bad design, but going to the trouble of removing the values from the application seems to violate the YAGNI principle. EDIT To clarify the question, I'm not concerned about the actual implementation. I'm concerned that I can either do a quick, bad thing, and justify it by saying YAGNI, or I can take a more defensive, high-effort approach, that even in the best case ultimately has low benefits. As a professional programmer does my decision to implement a design that I know is flawed simply come down to a cost/benefit analysis?

  • Online betting system design [closed]

    - by Rafal
    I am a Computer Science student, preparing for my exam in software engineering. I am strugging with answering one of the sample questions to the scenario below. My understanding is that the system design approach should probably be a mixture of agile and plan driven elements but - since I've no practical experience - it's hard for me to decide on the balance and tolls that should be used. I will appreciate any hints from experienced business analysts who were involved in similar kind of projects. Ray Sing is the owner of “Last Betz", a bookmakers with 7 outlets across Louth and Meath. With the advent of smartphones Ray would now like to allow his clients to place their bets online using their mobile devices. Clients would register for an account and password and would log their credit card details via the Last Betz website. To begin using the facility customers must 'load' their accounts with 100 euros. Any winnings, minus commission, will be placed in the account whilst any losses will be automatically deducted from the account. Assuming you have been selected to develop the above system: How would you approach the design of this system? Discuss the design methods and models you would use.

  • How to publish paid Android apps if you're not from US/UK

    - by Sheikh Aman
    I was pretty excited while creating one of my apps but as it turns out you can't actually sign up for Google Checkout if you don't live either in the USA or in the UK. And since Google Checkout is the only way Android Market will pay you, all my efforts seem to be going in vain. So because I live in India, I can't sell my apps. I tried contacting Google by various means on this, but haven't got any response so far. I tried searching the web as well just to find out that one can't be paid via any other way. I am pretty sure that many people here might have gone through the same problem. How did you solve it? I have a PayPal account and an AdSense account as well. Can they help in any way? And if nothing works out, how am I supposed to be selling my app?

  • .NET Properties - Use Private Set or ReadOnly Property?

    - by tgxiii
    In what situation should I use a Private Set on a property versus making it a ReadOnly property? Take into consideration the two very simplistic examples below. First example: Public Class Person Private _name As String Public Property Name As String Get Return _name End Get Private Set(ByVal value As String) _name = value End Set End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo Me.Name = txtInfo.ToTitleCase(Me.Name) End Sub End Class // ---------- public class Person { private string _name; public string Name { get { return _name; } private set { _name = value; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; this.Name = txtInfo.ToTitleCase(this.Name); } } Second example: Public Class AnotherPerson Private _name As String Public ReadOnly Property Name As String Get Return _name End Get End Property Public Sub WorkOnName() Dim txtInfo As TextInfo = _ Threading.Thread.CurrentThread.CurrentCulture.TextInfo _name = txtInfo.ToTitleCase(_name) End Sub End Class // --------------- public class AnotherPerson { private string _name; public string Name { get { return _name; } } public void WorkOnName() { TextInfo txtInfo = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo; _name = txtInfo.ToTitleCase(_name); } } They both yield the same results. Is this a situation where there's no right and wrong, and it's just a matter of preference?

  • Abstract Data Type and Data Structure

    - by mark075
    It's quite difficult for me to understand these terms. I searched on google and read a little on Wikipedia but I'm still not sure. I've determined so far that: Abstract Data Type is a definition of new type, describes its properties and operations. Data Structure is an implementation of ADT. Many ADT can be implemented as the same Data Structure. If I think right, array as ADT means a collection of elements and as Data Structure, how it's stored in a memory. Stack is ADT with push, pop operations, but can we say about stack data structure if I mean I used stack implemented as an array in my algorithm? And why heap isn't ADT? It can be implemented as tree or an array.

  • Is Python worth learning? Is it a useful tool?

    - by Kenneth
    I recently had a discussion with a professor of mine on the topic of web development. I had recently decided I would learn python to increase my arsenal of web tools which I mentioned to him at that time. He almost immediately asked why I would waste my time on that. I'm not certain but I think he recently started in on researching and studying web development so he could pick up the web development classes that haven't been taught for a while after the previous professor who taught those classes left. I've heard a lot about python and thought maybe he was mistaken about its usefulness. Is python a useful tool to have? What applications can it be used for? Is it better than other similar alternatives? Does it have useful applications outside of web development as well?
