  • Am I programming too slow?

    - by Jonn
    I've only been a year in the industry and I've had some problems making estimates for specific tasks. Before you close this, yes, I've already read this: http://programmers.stackexchange.com/questions/648/how-to-respond-when-you-are-asked-for-an-estimate and that's about the same problem I'm having. But I'm looking for a more specific gauge of experiences, something quantifiable or probably other programmer's average performances which I should aim for and base my estimates. The answers range from weeks, and I was looking more for an answer on the level of a task assigned for a day or so. (Note that this doesn't include submitting for QA or documentations, just the actual development time from writing tests if I used TDD, to making the page, before having it submitted to testing) My current rate right now is as follows (on ASP.NET webforms): Right now, I'm able to develop a simple data entry page with a grid listing (no complex logic, just Creating and Reading) on an already built architecture, given one full day's (8 hours) time. Adding complex functionality, and Update and Delete pages add another full day to the task. If I have to start the page from scratch (no solution, no existing website) it takes me another full day. (Not always) but if I encounter something new or haven't done yet it takes me another full day. Whenever I make an estimate that's longer than the expected I feel that others think that I'm lagging a lot behind everyone else. I'm just concerned as there have been expectations that when it's just one page it should take me no more than a full day. Yes, there definitely is more room for improvement. There always is. I have a lot to learn. But I would like to know if my current rate is way too slow, just average, or average for someone no longer than a year in the industry.

  • An experiment: unlimited free trial

    - by Alex.Davies
    The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

  • Function calls to calls in windows api

    - by Apeee
    I am a beginner, and learning C, I find it hard to grasp the whole programming concept. so hopefully this would help to clear up some things along the way. When programming in windows, which is my aim for the time being, it is really hard for me to understand how windows communicate with the programs that run on it. A question i have been pondering about is how when you incorporate a function call which is in another memory location on the disk or memory(not a function you yourself wrote and is included in the compilation), especially the windows API, does the compiler know where the function location is so when the program is run it can call that function? For example, a very simple program that displays a window which reads hello world. You would have to call windows API functions to achieve such features as creating the window, its size, colors and so on... So basically what I am struggling to grasp is how the programs I write communicate with the platform, framework they are run on(generally windows for Windows API). Apart from clarification on this one above, i would love a resource that explains this concept further. Thanks for your time!

  • Vista to Vista network visability issue

    - by Sk93
    Hi All, I've got a Vista Business PC and a Vista Business Laptop connected via a virgin media router (Netgear CG2100D) and I cannot get the two machines to see each other correctly over the network. The laptop is connected via wireless, whilst the pc is wired. Both are set to recieve their network settings automatically (DHCP) and both have the windows firewall (the only firewall on either) turned off completely. I can ping each machine fine from one another using the ip addresses, and I can also connect via \. However, connections via \ fail, and I cannot see the machines in the network map. I have tried turning netBIOS to be "always on" on both adapters, but this makes no difference. I've been messing around pretty much for 6 hours now and am getting quite fustrated by this! (my original aim was to get media sharing working, but I've pretty much abandoned that for now). Any ideas?

  • Command to determine whether ZooKeeper Server is Leader or Follower

    - by utrecht
    Introduction A ZooKeeper Quorum consisting of three ZooKeeper servers has been created. The zoo.cfg located on all three ZooKeeper servers looks as follows: maxClientCnxns=50 # The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. dataDir=/var/lib/zookeeper # the port at which the clients will connect clientPort=2181 server.1=ip1:2888:3888 server.2=ip2:2888:3888 server.3=ip3:2888:3888 It is clear that one of the three ZooKeeper servers will become the Leader and the others Followers. If the Leader ZooKeeper server has been shutdown the Leader election will start again. The aim is to check if another ZooKeeper server will become the Leader if the Leader server has been shut down. Question Which command needs to be issued to check whether a ZooKeeper server is a Leader or a Follower?

  • Is learning C# as a first language a mistake?

    - by JuniorDeveloper1208
    I know there are similar questions on here, which I've read, but I recently read this post by Joel Spolsky: How can I teach a bright person, with no programming experience, how to program? And it got me thinking about my way of learning and whether it might actually be harmful in the long run. I've dabbled with various languages but C# is my first serious one, I've read "Head First C#" and created a few projects. But after reading the post above I've found it a bit disheartening that I may be going about it all wrong, obviously I respect Joel's opinion which is what has thrown me a bit. I've started reading "Code" as recommended in the reading list and I'm finding it pretty hard going, although enjoyable. I feel like it's taken the shine off of my "noobish hacking about" in Visual Studio. So now I'm unsure as to what path I should take? Should I take a step back and follow Joel's advice and start reading? I guess my main aim is just to become a good programmer, like everyone else, but I don't want to be going into bad practice by learning a .NET language when someone who's opinion I respect thinks that it is harmful. Thoughts?

  • How to stop Word 2011 opening hyperlinks on click?

    - by John Yeates
    In previous versions of MS Word, there was a preference for the action to be taken when the user clicked a hyperlink: open it, or edit it. Word 2011 appears to have defaulted to opening the hyperlink, and I can't find the preference to change this behaviour. How can I change Word's default behaviour when a hyperlink is clicked to be editing the text of the hyperlink? Holding down a modifier key when clicking is not an acceptable solution, as the aim here is to prevent misclicks from causing web pages to open. Edit: the links need to stay as links in the saved document. But when clicked on my machine, they should not open; Word needs to default to just editing the link, so an inaccurate click does not take me out of the document into Safari. Older versions of Word had a preference controlling this, and Microsoft seem to have removed it and fixed the behaviour at the unsafe option in order to satisfy the point-and-drool crowd.

  • How do I create ruled lines in Word 2007?

    - by tobeannounced
    My aim is to set up Word to use the 'Cornell Notetaking method', and I would like to be able to have 'ruled lines' as part of my page in word. Currently, I have a split textbox, however obviously this does not allow the text to flow between lines. The underlining method does not work well enough, and I had read something about a college ruled template, however I was not able to find that. So is there any solution at all - by either creating lines in the textbox, or making the text flow between textbox rows?

  • copy WinXP Home recovery files to new SSD

    - by maGz
    My wife's Samsung netbook, which has Windows XP Home Edition OEM and a 5400 SATA 2 HDD, has finally crawled to (almost) a halt, and I've decided to install an OCZ SSD into it. The problem is that the machine came with no recovery media, but the recovery partition exists and I can boot into it. How can I go about creating a bootable DVD from that partition, and then boot off that to install on the SSD? NOTE: My aim after this is to upgrade to Windows 7 Home Premium, as the upgrade option is a lot cheaper than purchasing a retail or DSP equivalent.

  • Standalone server setup for compute capacity

    - by mikera
    I'm developing an application for my company that will require a lot of compute capacity (running some very big mathematical calculations), and looking for some form of server setup to do this. For various reasons, we want to run this on-site in our office rather than hosting it externally. It's been a while since I last had to set up my own servers so I thought I would tap into the collective wisdom of serverfault! My broad requirements are: Budget $30-50k, with an aim to get as much compute capacity as possible for that budget 64-bit servers suitable to run Ubuntu Linux + Java Some relatively standalone rack that can be installed in secure office space Fast/low latency network connections between the servers, but don't really care about connectivity to the outside world Storage capacity shared between the servers - they don't necessarily need their own storage providing they can be booted from a common image Downtime can be tolerated (since the calculations are run in batch mode) The software itself is fault-tolerant, so there is no need for extra resiliency in the server setup (cheap replaceable commodity parts will be fine in general) Given these requirements what kind of setup would you recommend and why?

  • How can I make this arcade-highscore game more fun/interesting?

    - by j-a
    I'm having difficulties getting the fun factor into this iPhone game, and I am looking for some ideas or advice. I was asked to generalize the question a bit. What are some techniques for arcade highscore games that can be applied to this game in order to: Make each second of the game fun and challenging, from the first second to the end of the game. Regardless of skill level. Make the player want to try again and again to beat the high score. Briefly about the game: you aim using your finger and pull the bow chord and release by lifting your finger. That part feels quite nice how the bow interacts with the finger. The game idea: hearts fall down and you get 1 pt for each heart you shoot. You start with a few arrows and every now and then a bag of arrow comes down which - if you hit it, you get more arrows. Once your out of arrows the game is over. So it is all about beating your previous high score or your friends high scores. Unfortunately I don't find it that fun. Thankful for any ideas/suggestions/thoughts on how to make it more fun/interesting.

  • How to plot 3D graphs in Excel from CSV data?

    - by Primx
    I have data formatted like this in a csv file: a, 1, 4, 6.0 a, 2, 42, 16.0 a, 5, 14, 69.3 a, 11, 4, 7.0 b, 1, 45, 6.0 b, 2, 45, 1.9 b, 9, 2, 4.4 b, 11, 4, 7.9 lines with first parameter a is one set of data, and first parameter b represents another set. My aim is to plot two lines on the same graph, one with points (1, 4, 6.0), (2, 42, 16.0), (5, 14, 69.3), (11, 4, 7.0) and the other with points (1, 45, 6.0), (2, 45, 1.9), (9, 2, 4.4), (11, 4, 7.9) I am able to import the data directly in MS Excel, but am not sure how to plot them. How can I plot this data?

  • How do 2D physics engines solve the problem of resolving collisions along tiled walls/floors in non-grid-based worlds?

    - by ssb
    I've been working on implementing my SAT algorithm which has been coming along well, but I've found that I'm at a wall when it comes to its actual use. There are plenty of questions regarding this issue on this site, but most of them either have no clear, good answer or have a solution based on checking grid positions. To restate the problem that I and many others are having, if you have a tiled surface, like a wall or a floor, consisting of several smaller component rectangles, and you traverse along them with another rectangle with force being applied into that structure, there are cases where the object gets caught on a false collision on an edge that faces the inside of the shape. I have spent a lot of time thinking about how I could possibly solve this without having to resort to a grid-based system, and I realized that physics engines do this properly. What I want to know is how they do this. What do physics engines do beyond basic SAT that allows this kind of proper collision resolution in complex environments? I've been looking through the source code to Box2D trying to find out how they do it but it's not quite as easy as looking at a Collision() method. I think I'm not good enough at physics to know what they're doing mathematically and not good enough at programming to know what they're doing programmatically. This is what I aim to fix.

  • What's the best way to use requestAnimationFrame and fixed frame rates

    - by m90
    I recently got into using the HTML5-requestAnimationFrame-API a lot on animation-heavy websites, especially after seeing the Jank Busters talk. This seems to work pretty well and really improve performance in many cases. Yet one question still persists for me: When wanting to use an animation that is NOT entirely calculated (think spritesheets for example) you will have to aim for a fixed frame rate. Of course one could go back to use setInterval again, but maybe there are other ways to tackle this. The two ways I could think of using requestAnimationFrame with a fixed frame rate are: var fps = 25; //frames per second function animate(){ //actual drawing goes here setTimeout(function(){ requestAnimationFrame(animate); }, 1000 / fps) } animate(); or var fps = 25; //frames per second var lastExecution = new Date().getTime(); function animate(){ var now = new Date().getTime(); if ((now - lastExecution) > (1000 / fps)){ //do actual drawing lastExecution = new Date().getTime(); } requestAnimationFrame(animate); } animate(); Personally, I'd opt for the second option (the first one feels like cheating), yet it seems to be more buggy in certain situations. Is this approach really worth it (especially at low frame rates like 12.5)? Are there things to be improved? Is there another way to tackle this?

  • How to optimize process of outlook files (*msg) conversion to .pdf?

    - by Lilly
    The aim is to convert several messages from Microsoft Outlook (2003 and/or 2007 versions) to .pdf files. Condition: One message should generate a corresponding single pdf file. If possible, pdf file should be named with date format YYYY-MM-DD (e.g. 2011-02-16.pdf). The current process, limited by softwares such as CutePDF, requires the conversion performed one message at a time. I'm looking for a solution that allows the conversion of several messages at once, but under the condition abovementioned (mainly: one message = one pdf file).

  • Moving a File While It's In Use -- How Does it work?

    - by Zaz
    I've noticed that on non-windows OS.... ie linux/mac i can do things like: - Send a zip to a friend over aim - Delete the file while it's in transfer And the transfer does not fail. Or, I can do operations like.. - start a movie - erase the file - the movie still plays to completion (read from disk, not just buffered in memory) Although the files are being "deleted", as i mentioned, they are actually being moved to a different location on the file system... ie a Trash directory or something. So it seems to me like the OS uses a pointer @ the file that is updated when it moves rather than accessing the files directly. Can anyone shed some light on how this AWESOME capability is actually implemented? I'm not even sure what to google to learn more about it. thank you.

  • Deploy multiple django instances on one Host [migrated]

    - by tvn
    I am trying to setup multiple Django instances on one Host with lighttpd. My problem is to get Djangos FCGI working on subdirectories served by my Webserver. So my aim is the following: www.myhost.org/django0 - django1.fcgi on localhost:3000 www.myhost.org/django1 - django2.fcgi on localhost:3001 www.myhost.org/django2 - django3.fcgi on localhost:3002 Unfortunately the following configuration doesn't even work for one: $HTTP["url"] =~ "^/django0/static($|/)" { server.document-root = "/home/django0/django/static/" } $HTTP["url"] =~ "^/django0/media($|/)" { server.document-root = "/usr/lib/python2.7/dist-packages/django/contrib/admin/media/" } $HTTP["url"] =~ "^/django0($|/)" { proxy.server = ( "" => ( ( "host" => "127.0.0.1", "port" => "3001", "check-local" => "disable", ) ) ) } The only response I get is an 404 and even this takes a long time till I get this. I found nothing suspicious neither in the access.log nor in the error.log.

  • How do I tell my parents that landing a job is what actually counts?

    - by shovonr
    On one side, I just want to get a degree with a 3.0 GPA. On the other side, my parents want more than just a 3. Now here's the thing. I program with a passion. I spend day and night programming. And I ace all my programming courses. However, I do terrible on all my elective courses -- such as writing, history, and all that stuff -- which only leaves me with a 3.1 to 3.2 GPA. And my parents want more. They think that university is like high school, where you need super-stellar grades to get to the next level. But they don't realize that good enough grades will land me a job. And they don't realize that a programmer needs to practice to become good at programming, and that having good skills is what will land a job in a nice software development company. Thankfully, though, they don't threaten to beat me with a baseball bat or anything like that. They just occasionally give me the little "tsk-tsk". But even that little "tsk-tsk" makes me feel guilty for opening up an IDE. And on top of that, I procrastinate because of that feeling of guilt. So now, I want to come clean with them. I want to know what's a good way to do that. [Edit] OK, so now, I realized, I should aim for higher grades, as some have suggested below.

  • Drupal site Instant Messaging [migrated]

    - by pthurmond
    I am trying to find a module or a standalone solution that I can turn into a module that will allow me to have an instant messaging system like Facebook does on a Drupal site that I am working on. I have never setup a chat system before. My particular requirements are rather stringent. It needs to be a solution where we host the chatting server (if one is needed separate from the website itself). It must use the site's login state (can't use an external system at all, that means no GTalk, Yahoo IM, or AIM). It also must be able to handle up to 1,000 users at any given time. I have looked through the Drupal community and I tried the DXMPP module, but it requires Jquery UI 1.8 and that doesn't work with all of the other things that my site uses (such as Homebox). We do have a Jabber server already setup and ready to go. Does anyone have any thoughts or options here? Thanks! EDIT: We are using Drupal 6.

  • How can 2 or more instances of the same program to communicate in local network?

    - by user1981437
    I want to create program which will be in use for few computers connected in local network. Basically the program aim is to keep track of all tables in a bar ( lets say ), which are reserved. When some user book a table as reserved the program should broadcast the table number to all other Pc's and mark the table as reserved. Since all computers use the same program, how is possible to create communication between all of them ? Should i use sockets to achieve this? If it matters, all of the computers have installed Linux OS,and the app will be developed in ruby,perl or php. Thank you.

  • Parsing a Directory of files - Check for a String

    - by i.h4d35
    This is my first post here so kindly pardon any mistakes that I have. I'm still learning to find my way around Stack Exchange. I am trying to write a Java program that tries to scan a Directory full of either .txt,.rtf or.doc files(and none other). The aim is to search all the files in the directory, and find out if a particular string exists in the file. If it does, it returns the string and the filename that it found the string in. The aim of this program is, it is a project for school wherein the program scans the personal folders of call center employees to check if they have stored any CC/DC nos and if yes, report the folder name - to reduce CC fraud. The search function was fairly straight forward and works when I individually specify the filename. However, the searching the directory and passing the files to the search function has me stumped. I've posted my code so far, if you guys could look thru it and give me some feedback/suggestions, I'd really appreciate it. Thanks in advance import java.io.*; import java.util.*; public class parse2{ void traverse(String directory) throws FileNotFoundException { File dir = new File(directory); if (dir.isDirectory()) { String[] children = dir.list(); for (int i=0; i<children.length; i++) { //System.out.println("\n" + children[i]); reader(children[i]); } } } void reader(String loc) throws FileNotFoundException { FileReader fr = new FileReader(loc); BufferedReader br = new BufferedReader(fr); Scanner sc = new Scanner(br); char[] chkArray; int chk=1; char ch; while(sc.hasNext()) { String chkStr = sc.next(); chkArray = chkStr.toCharArray(); if ((chkArray[0]=='4')&&(chkStr.length()>13)) { for(int i=0;i<chkArray.length;i++) { ch=chkArray[i]; if((ch=='0')||(ch=='1')||(ch=='2')||(ch=='3')||(ch=='4')||(ch=='5')||(ch=='6')||(ch=='7')||(ch=='8')||(ch=='9')) { chk=0; continue; } else { chk=1; break; } } if(chk==0) System.out.println("\n"+ chkStr); } else if((chkArray[0]=='5')&&(chkStr.length()>13)) { for(int i=0;i<chkArray.length;i++) { ch=chkArray[i]; if((ch=='0')||(ch=='1')||(ch=='2')||(ch=='3')||(ch=='4')||(ch=='5')||(ch=='6')||(ch=='7')||(ch=='8')||(ch=='9')) { chk=0; continue; } else { chk=1; break; } } if(chk==0) System.out.println("\n"+ chkStr); } else if((chkArray[0]=='6')&&(chkStr.length()>13)) { for(int i=0;i<chkArray.length;i++) { ch=chkArray[i]; if((ch=='0')||(ch=='1')||(ch=='2')||(ch=='3')||(ch=='4')||(ch=='5')||(ch=='6')||(ch=='7')||(ch=='8')||(ch=='9')) { chk=0; continue; } else { chk=1; break; } } if(chk==0) System.out.println("\n"+ chkStr); } } } public static void main(String args[]) throws FileNotFoundException { parse2 P = new parse2(); P.traverse("C:/Documents and Settings/h4d35/Desktop/javatest/chk"); } }

  • What scalability problems have you solved using a NoSQL data store?

    - by knorv
    NoSQL refers to non-relational data stores that break with the history of relational databases and ACID guarantees. Popular open source NoSQL data stores include: Cassandra (tabular, written in Java, used by Facebook, Twitter, Digg, Rackspace, Mahalo and Reddit) CouchDB (document, written in Erlang, used by Engine Yard and BBC) Dynomite (key-value, written in C++, used by Powerset) HBase (key-value, written in Java, used by Bing) Hypertable (tabular, written in C++, used by Baidu) Kai (key-value, written in Erlang) MemcacheDB (key-value, written in C, used by Reddit) MongoDB (document, written in C++, used by Sourceforge, Github, Electronic Arts and NY Times) Neo4j (graph, written in Java, used by Swedish Universities) Project Voldemort (key-value, written in Java, used by LinkedIn) Redis (key-value, written in C, used by Engine Yard, Github and Craigslist) Riak (key-value, written in Erlang, used by Comcast and Mochi Media) Ringo (key-value, written in Erlang, used by Nokia) Scalaris (key-value, written in Erlang, used by OnScale) ThruDB (document, written in C++, used by JunkDepot.com) Tokyo Cabinet/Tokyo Tyrant (key-value, written in C, used by Mixi.jp (Japanese social networking site)) I'd like to know about specific problems you - the SO reader - have solved using data stores and what NoSQL data store you used. Questions: What scalability problems have you used NoSQL data stores to solve? What NoSQL data store did you use? What database did you use before switching to a NoSQL data store? I'm looking for first-hand experiences, so please do not answer unless you have that.

  • Isolated storage misunderstand

    - by Costa
    Hi this is a discussion between me and me to understand isolated storage issue. can you help me to convince me about isolated storage!! This is a code written in windows form app (reader) that read the isolated storage of another win form app (writer) which is signed. where is the security if the reader can read the writer's file, I thought only signed code can access the file! If all .Net applications born equal and have all permissions to access Isolated storage, where is the security then? If I can install and run Exe from isolated storage, why I don't install a virus and run it, I am trusted to access this area. but the virus or what ever will not be trusted to access the rest of file system, it only can access the memory, and this is dangerous enough. I cannot see any difference between using app data folder to save the state and using isolated storage except a long nasty path!! I want to try give low trust to Reader code and retest, but they said "Isolated storage is actually created for giving low trusted application the right to save its state". Reader code: private void button1_Click(object sender, EventArgs e) { String path = @"C:\Documents and Settings\All Users\Application Data\IsolatedStorage\efv5cmbz.ewt\2ehuny0c.qvv\StrongName.5v3airc2lkv0onfrhsm2h3uiio35oarw\AssemFiles\toto12\ABC.txt"; StreamReader reader = new StreamReader(path); var test = reader.ReadLine(); reader.Close(); } Writer: private void button1_Click(object sender, EventArgs e) { IsolatedStorageFile isolatedFile = IsolatedStorageFile.GetMachineStoreForAssembly(); isolatedFile.CreateDirectory("toto12"); IsolatedStorageFileStream isolatedStorage = new IsolatedStorageFileStream(@"toto12\ABC.txt", System.IO.FileMode.Create, isolatedFile); StreamWriter writer = new StreamWriter(isolatedStorage); writer.WriteLine("Ana 2akol we ashrab kai a3eesh wa akbora"); writer.Close(); writer.Dispose(); }

  • Graph drawing for the Web 2.0

    - by tokel
    Hi. There are a lot of chart drawing libraries out there, but what I am looking for is an interactive(!) graph (nodes and edges) drawing library. At best some kind of AJAX, but I am also open for other technologies (Java, Flash). However I would really prefer an AJAX implementation. Also only Open Source framework suggestions please (I already know about yFiles). The thing I have in mind is a bit like GWTUML. That is quite nice already, but misses an API for their graph drawing. It seems that it is an custom implementation for their product. Also some layout algorithms would be nice. Is there really no library around for that task?
