• Making a web interface for neo4j

  - by user2898839

  I have a local neo4j database server and I want to build a web interface using javascript. Ideally I want to do all the querying and display the result client side for the website. I am mostly a Java programmer and unfortunately don't have much experience with Javascript. How can I do a cypher query from the website and return the result in a format which I can display easily in a table for example? I have seen examples of doing the querying server side with servlets or node.js but really would like to just have the neo4j server and the website client. I would be interesting in seeing a small working example if it is at all possible. Thanks for your time.

• What programming languages do you consider indispensable in your experience?

  - by Federico Ramponi

  Each programming language comes with its concepts, best practices, libraries, tools, community, in one word: culture. Learning more than one programming language will make you a better programmer, for the more concepts you learn, the faster you will feel comfortable when the next language or technology will come. Mine, so far, are C, some C++, and Python, and many times I read that it would be worth learning LISP, for "the profound enlightenment experience you will have when you finally get it" (quoting Eric Raymond). My questions are: Which is the next one you would consider a good investment to learn? Of the many programming languages you have learnt and worked with, which ones do you consider to be an essential part of one's CS culture, and why? EDIT. Further question: is there any language you would sincerely advise to avoid as a waste of time? (The famous, and questionable, slatings in this letter from Dijkstra come to my mind.)

• How can I know if a computer supports hardware-assisted virtualization before I purchase the computer?

  - by Poaters

  I'm an iPhone programmer who is no longer in possession of a personal Mac computer on which to use XCode. I have two Windows desktops, and I would like to run OS X in VMWare rather than purchase Apple's expensive hardware. However, neither of my machines supports hardware-assisted virtualization, which is required to virtualize OS X. I went shopping online for a computer today, since I've been planning to purchase a laptop anyway, but sites like Best Buy don't appear to give any indication of whether or not a product supports this. Is there any other site out there or some trick to figuring this out other than buying the machine and running Microsoft's nifty little detection tool?

• What would be the simplest way to deal with a text file using JSP?

  - by Nano Taboada

  First and foremost I should acknowledge that I have no experience at all using Java ServerPages, but I'm positive about achieving this task if you guys help me out a bit since it doesn't seem like something difficult for a seasoned JSP programmer. Anyway the thing is, there's an actual running JSP application within a *NIX box which I somewhat administer with kind of good permissions. The idea is to create a new but dead simple JSP page to control some Korn Shell scripts I've got running there. So the goal is to make some sort of HTML form that will be writing some kind of scriptStatus.on / scriptStatus.off file: #!usr/bin/ksh # coolScript.sh # This is my cool script that is being launched by cron every 10 minutes. if [ -e scriptStatus.off ] then # monitor disabled else # monitor enabled fi which then can be checked for existence within the running script, therefore allowing to easily activate / deactivate it without actually have do deal with cron. Please let me know if all this does make any sense and don't hesitate to ask as much questions as needed. Thanks much in advance!

• Does anyone else think instance variables are problematic in database-backed applications?

  - by Ben Aston

  It occurs to me that state control in languages like C# is not well supported. By this, I mean, it is left upto the programmer to manage the state of in-memory objects. A common use-case is that instance variables in the domain-model are copies of information residing in persistent storage (i.e. the database). Clearly this violates the single point of authority principle, and "synchronisation" has to be managed by the developer. I envisage a system where instead of instance variables, we have simple public access/mutator methods marked with attributes that link them to the database, and where reads and writes are mediated by a framework that decides whether to hit the database. Does such a system exist? Am I completely missing the point, or is there some truth to this idea?

• Clojure for a lisp illiterate

  - by dbyrne

  I am a lifelong object-oriented programmer. My job is primarily java development, but I have experience in a number of languages. Ruby gave me my first real taste of functional programming. I loved the features Ruby borrowed from the functional paradigm such as closures and continuations. Eventually, I graduated to Scala. This has been a great way to gradually learn to approach non-trivial problems in a functional manner. Now I am interested in Clojure. I know all the sexy features that make it enticing (software transactional memory, macros, etc.), but I just can't get used to "thinking in lisp". I've seen Rich Hickey's screencasts aimed at java programmers, but they are geared towards explaining language features and not approaching real world problems. I am looking for any advice or resources which have made this transition easier for others.

• Why isn't my favicon appearing in IE7/8?

  - by X3Maverick

  Page of interest: https://www.gsb-yourbank.com/test/ ICO file: https://www.gsb-yourbank.com/test/favicon.ico My favicon is a 16x16 resolution, 16-color ICO file. It will not appear in IE 7/8 no matter what I do! I've tried everything I can think of, including: generating the ICO with a variety of different utilities, changing the syntax of the favicon link elements in the document head, using absolute, relative, and root-relative URLs in the favicon link elements, using a PNG instead of an ICO file, ensuring that I am uploading the file via FTP in binary mode, As a longtime web developer/programmer, I can't believe that this is tripping me up. Any help would be greatly appreciated.

• What's the silliest programming mistake you've ever done? [closed]

  - by bgo

  Despite not being a professional programmer, i use python or c to accomplish simple tasks. Once I needed a nasty equation to use with various data for physics lab. I thought that it would take a few hours if i used some mechanic calculator. Then i've written a python script to make things easier but something was wrong. After finding my mistakes one of which was forgetting to put ":", i realized that it had already took 2-3 hours, not to mention inventing satanic arithmetic techniques since i thought the errors was caused by my math :) Sometimes when you don't see it, you don't see it! Now i can find the syntax errors without thinking for a moment :) Any similar annoying mistakes that you've experienced?

• Which programming paradigm or language open most your mind?

  - by Dom De Felice

  It is often said that some programming languages exist that once grasped can open your mind and change the way you write software. A sort of "software design enlightenment", we can say. I heard this about Lisp, Smalltalk, Haskell, pure functional programming in general.. What are your experiences about this? I know that the right language to use depends on your needs, but I would like to know the one that better improve your programming skills in general. What do you think would be the best language/paradigm to learn to end up being a better programmer in the long run?

• Enjoy bug fixing more than coding from scratch

  - by kylex

  As I get more and more into my job I've had a lot of opportunity to code new projects from scratch. Almost every programmer I know really appreciates that opportunity. But the further I go into it, the more I enjoy bug fixing. In fact, if I can spend a whole day looking over code, whether it be mine or someone else's code, and find some obscure bug, I feel much more accomplished than when I create code. Does anyone else feel this way, and are there any job advantages to this?

• Learning C++ from AS3

  - by grey

  I'm a decent AS3 programmer. I work in games, and that is my reason for programming. While there is much I can accomplish with Adobe AIR, my understanding at this point is that learning C++ is probably a good direction to take. I would learn a lot of valuable lower level programming if I needed it down the road, and I would have an easier time learning other C oriented languages. I see a lot of information for people looking to learn AS3 who know C++, but not the other way around. Why C++? Cross platform compatibility is important to me, so I'm not particularly interested in C# or Objective-C at this junction. I'm also aware of HaXe, and while I love the concept, after doing some research I'm worried about investing a lot of time into something so recent with limited learning resources and documentation. I'm looking for advice and resources (books, articles) related to this topic. Thanks in advance!

• Is it possible to have a mysql table accept a null value for a primary_key column referencing a diff

  - by Dr.Dredel

  I have a table that has a column which holds the id of a row in another table. However, when table A is being populated, table B may or may not have a row ready for table A. My question is, is it possible to have mysql prevent an invalid value from being entered but be ok with a NULL? or does a foreign key necessitate a valid related value? So... what I'm looking for (in pseudo code) is this: Table "person" id | name Table "people" id | group_name | person_id (foreign key id from table person) insert into person (1, 'joe'); insert into people (1, 'foo', 1)//kosher insert into people (1, 'foo', NULL)//also kosher insert into people(1, 'foo', 7)// should fail since there is no id 7 in the person table. The reason I need this is that I'm having a chicken and egg issue where it makes perfect sense for the rows in the people table to be created before hand (in this example, I'm creating the groups and would like them to pre-exist the people who join them). And I realize that THIS example is silly and I would just put the group id in the person table rather than vice-versa, but in my real-world problem that is not workable. Just curious if I need to allow any and all values in order to make this work, or if there's some way to allow for null.

• Random numbers from binomial distribution

  - by Sarah

  I need to generate quickly lots of random numbers from binomial distributions for dramatically different trial sizes (most, however, will be small). I was hoping not to have to code an algorithm by hand (see, e.g., this related discussion from November), because I'm a novice programmer and don't like reinventing wheels. It appears Boost does not supply a generator for binomially distributed variates, but TR1 and GSL do. Is there a good reason to choose one over the other, or is it better that I write something customized to my situation? I don't know if this makes sense, but I'll alternate between generating numbers from uniform distributions and binomial distributions throughout the program, and I'd like for them to share the same seed and to minimize overhead. I'd love some advice or examples for what I should be considering.

• Which is the future of web development: HTML5 or Silverlight(or other RIA framework)?

  - by Morgan Cheng

  My colleagues have a heated debate on what is the future of web development. One side is supporting HTML5 and the other is supporting Silverlight. There is no conclusion of the debate yet. In my humble opinion as a programmer, HTML5 will not improve programming productivity, while Silverlight will. In my understanding, programmers still need to program in JavaScript to take advantage of HTML5. For Silverlight, we can use C# which is static-type language. A lot of coding defects can be found in compilation time. For HTML5, different browsers might still have different behavior even though there is spec. For Silverlight, generally what works in IE will work the same way in other browsers. Just my thoughts. Any idea on how to choose future direction of web development?

• Latitude & longitude coordinates of Australian states/territories for database using Google Maps

  - by RMW

  Hi, We have a database which has location-based search using Google Maps API. However searching by state or territory in Australia is problematic because Google Maps locates these at the centre of the states and most population centres in Australia are on the coast. We need to hand code in the latitudes and longitudes so that when someone searches for the state 'NSW', for example, the database returns relevant results. Does anyone know where to find a list of the coordinates for the boundaries of Australian states & territories to code into the database? This will save our busy programmer a lot of time. Thanks in advance.

• How can I make a recursive version of my iterative method?

  - by user247679

  Greetings. I am trying to write a recursive function in Java that prints the numbers one through n. (n being the parameter that you send the function.) An iterative solution is pretty straightforward: public static void printNumbers(int n){ for(int i = 1; i <= n; i++){ System.out.println(i); i++; } As a novice programmer, I'm having troubles figuring out how a recursive version of this method would work. Any bright ideas? Thanks for reading my problem!

• Upload a .pdf file to a Sharepoint Document Library using Access vba

  - by Jim Shaffer

  Within an Access 2007 application, I'm creating a static report in .pdf format. I want to create it, then export the static report (not the data itself) to a Sharepoint Document Library. The intent is for it to be a public repository, no versioning. Each report will carry a unique name. I'm a seasoned vba programmer, but using Sharepoint services is new to me. How do I go about doing this? Assume I can identify the file name and location after I've generated it, and I know the Sharepoint library URL, and have permissions. Where do I go from there?

• which technology is best for a Facebook application Ruby on Rails or C# and ASP?

  - by Johnny

  hi, My friend and I want to write a Facebook application. We've narrowed down the list of possible technologies to Ruby on Rails and C# with ASP. Here are the pros and cons we've thought of. Cons: ASP - proprietary tools like Visual Studio etc. cost (lots of) money. We both don't know ASP (although we're not bad at C#). RoR - It's scripting so might be harder to maintain. My friend doesn't know RoR at all (but he's a fairly proficient programmer so will probably be able to pick it up quickly). Pros: ASP - Facebook has an official SDK for .NET. RoR - I know RoR. It's open source, free and has fast development time. What says the community? Is there something we haven't thought of?

• Unable to parse variable length string separated by delimiter

  - by Technext

  Hi, I have a problem with parsing a string, which consists only of directory path. For ex. My input string is Abc\Program Files\sample\ My output should be Abc//Program Files//sample The script should work for input path of any length i.e., it can contain any no. of subdirectories. (For ex., abc\temp\sample\folder\joe) I have looked for help in many links but to no avail. Looks like FOR command extracts only one whole line or a string (when we use ‘token’ keyword in FOR syntax) but my problem is that I am not aware of the input path length and hence, the no. of tokens. My idea was to use \ as a delimiter and then extract each word before and after it (), and put the words to an output file along with // till we reach the end of the string. I tried implementing the following but it did not work: @echo off FOR /F "delims=\" %%x in (orig.txt) do ( IF NOT %%x == "" echo.%%x//output.txt ) The file orig.txt contains only one line i.e, Abc\Program Files\sample\ The output that I get contains only: Abc// The above output contains blank spaces as well after ‘Abc//’ My desired output should be: Abc//program Files//sample// Can anyone please help me with this? Regards, Technext

• Are there any good materials or examples on creating a custom Designer in the Delphi IDE

  - by Mark Elder

  I am working on creating a custom form designer in the Delphi IDE. I'm trying to use the RegisterCustomModule, TBaseCustomModule, and ICustomModule functions, classes, and interfaces. My first question on this pointed me to the Delphi Developer's Handbook and the idea that I could even create a custom form designer. However, that book seems to be all Delphi 3 information and things have really changed since then. I'm not finding any material in the Delphi Help file, and searches have not returned very much. I did find the Accidental Programmer's page on the Open Tools, but that looks like it was last up dated in 1998? It does at least have the correct unit names and uses the new interfaces. I'm willing to track down and buy an older book if that is the best reference.

• C++ for games

  - by Bi

  Hi I am a relatively newbie in C++ and worked in the game industry for a few months. I am looking to get back to the industry and understand that one needs to be a very good C++ programmer (mainly bcos of how competitive it is to get into making games). I was wondering if there are really good websites online that would help with that. Basically I am looking for something that would help me MASTER C++ concepts as well as help me be a good coder through programming examples that I can code. Thanks Bi

• Easily digestible UI tips for developers

  - by David

  What are some key UI design tips that every developer should know? While there are a number of UI resources for developers (for example, Joel Spolsky's User Interface Design for Programmers), I'm interested in more of a bullet list that can be communicated in 1 to 2 pages. I'm interested in more tactical, day-to-day UI tips, as opposed to overarching UI design goals that would be covered in a UI design meeting (presumably attended by at least one person with a good UI sense). A collection of these tips might cover about 80% of the cases that an everyday programmer would come across.
