• TypeScript or JavaScript for noob web developer [closed]

  - by Phil Murray

  Following the recent release by Microsoft of TypeScript I was wondering if this is something that should be considered for a experienced WinForm and XAML developer looking to get into more web development. From reviewing a number of sites and videos online it appears that the type system for TypeScript makes more sense to me as a thick client developer than the dynamic type system in Javascript. I understand that Typescript compiles down to JavaScript but it appears that the learning curve is shallower due to the current tooling provided by Microsoft. What are your thoughts?

  - by Demla Pawan

  I mean, How to self Motivate to get a job at google or create another google in future. ,as there is no mentor who can guide me on this topic, so asked it here: I'm a Graduate in BE IT,but with less grades,with interest in learning new programming languages, but not yet done anything great like developed some system or anything. And I'm left with 2 more years to prove my worth to someone. So,is their a quick guide to start learning a language and then just go on implementing your ideas and it gets appreciated or I get a good Job ant Big MNC's. By the way, I just build one website for my one client and running my wordpress blog. And I had tried my hands on basic of C++,Java,JS,JSP,PHP,Ubuntu,web designing in past.

• Resources for up-to-date Delphi programming

  - by Dan Kelly

  I'm a developer in a small department and have been using Delphi for the last 10 years. Whilst I've tried to keep up-to-date with movements there are a lot of changes that have occurred between Delphi 7 and (current for us) 2010. Stack Exchange and here have been great for answering the "how do you" questions, but what I'd like is a resource that shows great examples of larger scale programming. For example is there anywhere that hosts examples of well written, multi form applications? Something that can be looked at as a whole to illustrate why things should be done a certain way?

• problem using pydoc in python

  - by rohanag

  I'm using pydoc in python 2.7.3 to generate documentation for a file called PreProcessingAPI.py which contains a class called PreProcessingAPI In PreProcessingAPI.py, I have the following import in the beginning of the file: from __future__ import division from re import * from nltk.stem import porter The problem is, in the documentation generated by pydoc, nltk.stem.porter is shown as a Module. There is also a DATA heading with all sorts of variables I do not know about. Is there a way to avoid these variables and avoid showing nltk.stem.porter in the modules? I'm running the following command to generate documentation python pydoc.py -w PreProcessingAPI.py I've put the file pydoc.py in the directory containing my file. Here is the file generated: https://www.dropbox.com/s/4rb6ut99o25mwly/PreProcessingAPI.html

• What should I learn to create web-services like ones listed? [closed]

  - by Gerald Blizz

  I am very inspired by websites like imgur, dropbox, screencloud, maybe w3schools...you get my point. Fresh web-services with some new idea, not big portals but something simple yet useful and used by many people, something simple and new. What aspects of my developer career should I focus to be able to build such things on my own if I have enough ideas? (Sure if it ends up being popular I can get more developers to help me and so on, but at first I can do it alone, right?) I am currently a PHP web-developer, I know HTML+CSS+JS+AJAX+JQuery. But even like that there still is web-design, there are a lot of paths: websites for enterprise, startups, webservices, entertainment websites and serious bank/document flow systems, frameworks used for big systems, different approaches for little ones, etcetcetc. Which path should I take to be able to start my own projects like the ones that I listed on top which inspire me?

• Hosting WCF over internet

  - by user1876804

  I am pretty new to exposing the WCF services hosted on IIS over internet. I will be deploying a WCF service over IIS(6 or 7) and would like to expose this service over the internet. This will be hosted in a corporate network having firewall, I want this service to be accessible over the internet(should be able to pass through the firewall) I did some research on this and some of the pointers I got: 1. I could use wsHTTPBinding or nettcpbinding (the client is intended to be .net client). Which of the bindings is preferable. 2. To overcome the corporate I came across DMZ server, what is the purpose of this and do I really need to use this). 3. I will be passing some files between the client and server, and the client needs to know the progress of the processing on server and the end result. I know this is a very broad question to ask, but could anyone give me pointers where I could start on this and what approach to take for this problem.

• How to explain OOP to a matlab programmer?

  - by Oak

  I have a lot of friends who come from electrical / physical / mechanical engineering background, and are curious about what is "OOP" all about. They all know Matlab quite well, so they do have basic programming background; but they have a very hard time grasping a complex type system which can benefit from the concepts OOP introduces. Can anyone propose a way I can try to explain it to them? I'm just not familiar with Matlab myself, so I'm having troubles finding parallels. I think using simple examples like shapes or animals is a bit too abstract for those engineers. So far I've tried using a Matrix interface vs array-based / sparse / whatever implementations, but that didn't work so well, probably because different matrix types are already well-supported in Matlab.

• Save .mov file with applescript

  - by Frost Shadow

  I've installed the Perian addon for Quicktime so it can open .flv files, and then I can save them as .m4v or .mov. I'm trying to make an Applescript to convert from .flv to .m4v automatically by using this tutorial and butchering their example applescript file, which normally converts ChemDraw files (.cdx, .cml, .mol) to .tiff, so that it instead uses Quicktime to save the .flv files as .m4v. When I try to use it, though, I get an error "QuickTime Player got an error: document 1 doesn't understand the save message". My save message is currently: save first document in target_path as ".m4v" which looks like the QuickTime dictionary's instructions: save specifier : The document(s) or window(s) to save. [as saveable file format] : The file format to use. I've also tried "m4v", without the period, and still get the error. Is my Save direction wrong, or is it probably an error from trying to use Quicktime instead of the original ChemDraw? I tried to change references to .cdx, .cml, .mol, .tiff, and ChemDraw to .flv, .m4v, and QuickTime respectively, but maybe it's more complicated than that? I would, in fact, appreciate any example showing how to save an application file (ex: a TextEdit .rtf or .txt), as I can't seem to get any kind of file to save using applescript.

• how to improve design ability

  - by Cong Hui

  I recently went on a couple of interviews and all of them asked a one or two design questions, like how you would design a chess, monopoly, and so on. I didn't do good on those since I am a college student and lack of the experience of implementing big and complex systems. I figure the only way to improve my design capability is to read lots of others' code and try to implement myself. Therefore, for those companies that ask these questions, what are their real goals in this? I figure most of college grads start off working in a team guided by a senior leader in their first jobs. They might not have lots of design experience fresh out of colleges. Anyone could give pointers about how to practice those skills? Thank you very much

• Getting work done in a small office

  - by three-cups

  I work in an office area of ~450sqft. There are a total of 7 people working in the office. I've been finding it hard to concentrate on my work (writing code) because of the distractions going on around me. The distractions are both work-related and non-work-related conversations. I'm trying to figure out what to do in this situation. I want to be part of the team, and I want to get my work done to the best of my ability. I can easily think of two options that I don't like: Stay where I am, not be able to concentrate and get less work done Move somewhere else. (This is tough because I code on a desktop, so I'm not very mobile.) But what are other options? I'm going to talk this through with my team in the next couple days. Any advice or solutions would be great.

• How to translate formulas into form of natural language?

  - by Ricky

  I am recently working on a project aiming at evaluating whether an android app crashes or not. The evaluation process is 1.Collect the logs(which record the execution process of an app). 2.Generate formulas to predict the result (formulas is generated by GP) 3.Evaluate the logs by formulas Now I can produce formulas, but for convenience for users, I want to translate formulas into form of natural language and tell users why crash happened.(I think it looks like "inverse natural language processing".) To explain the idea more clearly, imagine you got a formula like this: 155 - count(onKeyDown) >= 148 It's obvious that if count(onKeyDown) 7, the result of "155 - count(onKeyDown) = 148" is false, so the log contains more than 7 onKeyDown event would be predicted "Failed". I want to show users that if onKeyDown event appears more than 7 times(155-148=7), this app will crash. However, the real formula is much more complicated, such as: (< !( ( SUM( {Att[17]}, Event[5]) <= MAX( {Att[7]}, Att[0] >= Att[11]) OR SUM( {Att[17]}, Event[5]) > MIN( {Att[12]}, 734 > Att[19]) ) OR count(Event[5]) != 1 ) > (< count(Att[4] = Att[3]) >= count(702 != Att[8]) + 348 / SUM( {Att[13]}, 641 < Att[12]) mod 587 - SUM( {Att[13]}, Att[10] < Att[15]) mod MAX( {Att[13]}, Event[2]) + 384 > count(Event[10]) != 1)) I tried to implement this function by C++, but it's quite difficult, here's the snippet of code I am working right now. Does anyone knows how to implement this function quickly?(maybe by some tools or research findings?)Any idea is welcomed: ) Thanks in advance.

• Is there something better than a StringBuilder for big blocks of SQL in the code

  - by Eduardo Molteni

  I'm just tired of making a big SQL statement, test it, and then paste the SQL into the code and adding all the sqlstmt.append(" at the beginning and the ") at the end. It's 2011, isn't there a better way the handle a big chunk of strings inside code? Please: don't suggest stored procedures or ORMs. edit Found the answer using XML literals and CData. Thanks to all the people that actually tried to answer the question without questioning me for not using ORM, SPs and using VB edit 2 the question leave me thinking that languages could try to make a better effort for using inline SQL with color syntax, etc. It will be cheaper that developing Linq2SQL. Just something like: dim sql = <sql> SELECT * ... </sql>

• Transiltion from maintenance programing to design

  - by andrew wang

  What to do guys do develop a design for a s/w for a given set of requirements? I like many people joined a Semiconductor MNC and got stuck in maintenance for quite a couple of years. My work was usually changing a lines of code for windows drivers supplied by my company or a couple of small script (style like) C programs for validating h/w. As a result I developed the bad habit of 'programming by coincidence'. I have not developed the ability for designing tools/programs from scratch. I was the only s/w member of the local team and thus some grunt work from the well established other site of the company came to be done by me. Now I have moved to a different company and thus finding developing from scratch very difficult. How do I unlearn my bad habit and develop this ability of designing s/w and then coding it ?

• Why are part-time jobs in programming an anomality?

  - by Mikle

  I've recently quit my full time developing job at mega-corp, and I decided that I'll look for a part time job. Since then I've talked to half a dozen potential employers, and every one of them had the same reaction when I said the magic words "part-time" - they all closed up and became suspicious. Now, I understand that it might just be me, so as control I asked every one of them what if I were willing to work full time, and they all said I would probably get an offer. My question is two fold: Why, as an employer, would you give up a competent, even great, developer, simply because he wants to work 3 days a week and not 5? How do I sell the story of part time job better? I usually just list my reasons which are that I prefer that balance currently in my life and that I want to work on my own projects, but it leaves them even more suspicious - am I going to start something myself and quit? Am I just lazy?

• Health problem of a programmer

  - by gunbuster363

  Hi all, I've been annoyed by this fingers ache for quite a long time, my fingers ache because of too much mouse clicking during office hour plus play games after work. I forget game for a while and my fingers are getting better, but still my right pointing finger would feel pressure when I click the mouse. I haven't go to a doctor because I afraid the fee would be high and he would just suggest me too get rest for the fingers, also, I don't know what kind of doctor should I go and see. My fingers get less pressure if I use my expensive deathadder ( what a shame, I bought this for gaming, but now I use it for rest ) at home because its buttons are softer, however I cannot have such expensive mouse at my office because I am afraid people would steal it. I use some trick when I am using the mouse such as single-click open a file, adding more shortcuts at desktop for common jobs, do you guys have some other tips for me? Thank you.

• .Net search engine architecture and technology choice

  - by shrivb

  I am in the process of designing a search engine for an asp.net site. The site currently uses Microsoft Indexing Server to index and search content which range from simple text files to MS documents to PDFs. MIS is also used to crawl File servers. MIS in tandem with Index Server Companion crawls for content from external sites. I intend to replace MIS with the indexer/crawler I am trying to build. Since my platform is completely on the Microsoft stack, I cant afford to have a Java application server. Thus, Solr, and effectively, SolrNet is ruled out. With this being the context, I have couple of questions. 1.Technology choice I had done my initial investigation and looked at Lucene.Net. There seemed to be 2 issues in using Lucene.Net. First being, it cant crawl external content. There doesn't seem to be a direct port of Nutch in .Net. Second, since it is just an indexer, it cant parse various document types. The parsing is left to the developer. So, what would be best technology choice on the .Net platform to achieve indexing & crawling? Are there any .Net open source libraries available for document parsing? 2.Architectural pattern Is there any general architectural pattern or best practice that needs to be followed in designing such a search engine? Thanks in advance.

• What is constructor injection?

  - by TheSilverBullet

  I have been looking at the terms constructor injection and dependency injection while going through articles on (Service locator) design patterns. When I googled about constructor injection, I got unclear results, which prompted me to check in here. What is constructor injection? Is this a specific type of dependency injection? A canonical example would be a great help! Edit Revisiting this questions after a gap of a week, I can see how lost I was... Just in case anyone else pops in here, I will update the question body with a little learning of mine. Please do feel free to comment/correct. Constructor injection and property injection are two types of Dependency Injection.

• Project Codenames - Yea or Nay?

  - by rmx

  Where I work, most of our projects have (or at least attempt) descriptive, useful names. However we have a few with names that make no sense: I found that an assembly named WiFi which actually has nothing whatsoever to do with wi-fi, but is a codename. When I asked why, I was told that it's to protect company secrets incase some intern has few too many at the pub on Friday and starts chatting about the brand new 'WiFi' project he's been working on. Its clear that some people find enjoyment in finding silly / amusing codenames for their projects (like in this question). My question is: is it really a good idea to use codenames for your projects or are you better off spending the time to decide upon a descriptive name? My opinion is that in the long-run its better to give your projects relevant names. My reasoning is that if you can't think of a decent name, perhaps you don't really know the requirements well enough. I think there are better ways to 'protect company secrets' and I find it quite confusing when the name does not correlate at all with the content. It's just common sense, surely?! So do you use codenames and what the your reasons for or against this seemingly common, yet annoying (to me at least) practice?

• Node.JS testing with Jasmine, databases, and pre-existing code

  - by Jim Rubenstein

  I've recently built the start of a core system which is likely going turn into a monster product. I'm building the system with node.js, and decided after I got a small base built, that It'd be a great idea to start using some sort of automated test suite to test the application. I decided to use jasmine, as it seems pretty solid and has a lot of features for stubbing spying and mocking methods and classes. The application has a lot of external data stores and api access (kestrel, mysql, mongodb, facebook, and more). My issue is, I've got a good amount of code written that I want to start testing - as it represents the underpinnings of the application. What are the best practices for testing methods/classes that access external APIs that I may or may not have control over? As an example, I have a data structure that fetches a bunch of data from a MySQL database. I want to test the method that retrieves the data; and I'm not sure how to go about it. I could test the fetch method which is supposed to return an array of objects, but to isolate the method from the database, I need to define my own fixture data. So what I end up doing is stubbing the mysql execution, and returning a static dataset. So, I end up writing a function that returns the dataset that makes my test pass. That doesn't seem to actually test the code, other than verifying a method is being called. I know this is kind of abstract and vague, it seems that the idea of testing is very much abstract though, so hopefully someone has some experience and can guide me in the right direction. Any advice, or reading I can do is more than welcomed. Thanks in advance.

• What all items can I put on my resume without it looking tacky? [closed]

  - by Earlz

  I've been searching for work, and so far it's very hard for me to even get a call back. So, I'm looking at adding things to my resume. I know a resume doesn't need to be over 2 pages. I have the basics: Objective/personal info General skills (languages known, etc) Work experience Some things I'm considering adding to it: My college education (though I don't have a degree) Awards given for programming skills in high school (curriculum contests and AP test scores) Open source projects? Would any of these 3 items look tacky? And I only have about 1.5 years of work experience, but I've been programming since I was 13. Is there anything else I can add to my resume that would give me a better chance of getting my foot in the door?

• how do you read from system.out in Java [closed]

  - by Dan

  I'm trying to create a word scramble game and so far I have taken a vector of randomly assorted strings that contains both words and hints and split them into two vectors. I have randomly scrambled the word and set this all up in text boxes. Right now I'm stuck because I have a text box that takes input but I'm not sure how to read that in? I want the user to type the unscrambled word into the text box and have it calculate as correct and move on to the next word immediately. I also don't know how to get the keys working. I want the "?" character to be the hint button that shows the hint. At the moment the hint box works if I type the question mark in using the System.in but it doesn't work if I type it directly in to the text box. The characters are showing up in the text box but nothing is working after that.

• On-the-fly graphical representation of code

  - by dukeofgaming

  I know about Omondo's plugin for live code-UML synchronization in Eclipse, but I was wondering if there was any other tool/IDE/IDE-extension that has some form of live graphical code representaiton (structural, flow, call-stacks, dependencies, etc.). I'm essentially looking for richer visual feedback on code while programming, not really looking for purely graphical code editors, though round-trips would be nice (edit graphically, code gets modified; edit code, representation gets modified). If you don't know about any graphical live documentation tool for code, maybe someone that can coexist with code, such as MySQL Workbench or Enterprise Architect.

• What is the supposed productivity gain of dynamic typing?

  - by hstoerr

  I often heard the claim that dynamically typed languages are more productive than statically typed languages. What are the reasons for this claim? Isn't it just tooling with modern concepts like convention over configuration, the use of functional programming, advanced programming models and use of consistent abstractions? Admittedly there is less clutter because the (for instance in Java) often redundant type declarations are not needed, but you can also omit most type declarations in statically typed languages that usw type inference, without loosing the other advantages of static typing. And all of this is available for modern statically typed languages like Scala as well. So: what is there to say for productivity with dynamic typing that really is an advantage of the type model itself?
