  • I can write code...but can't design well. Any suggestions?

    - by user396089
    I feel that I am good at writing code in bits and pieces, but my designs really suck. The question is how do I improve my designs (in order to become a better designer). I think schools and colleges do a good job of teaching people as to how to become good at mathematical problem solving, but lets admit the fact that most programs taught at school are generally around 1000 - 2000 lines long, which means that it is mostly an academic exercise and no way reflects the complexity of real world software (a few hundred thousand to millions of lines of code). This is where I believe that even projects like topcoder/project euler also won't be of much help, they might sharpen your mathematical problem solving ability - but you might become a theoretician programmer; someone who is more interested in the nice, clean stuff, and someone who is utterly un-interested in the day to day mundane and hairy stuff that most application programmers deal with. So my question is how do I improve my design skills? That is the ability to design small/medium scale applications that will go into a few thousand of lines of code? How can I learn design skills that would help me build a better html editor kit, or some graphics program like gimp?

  • How to avoid being fooled

    - by Dacav
    I'm a big fan of the OpenSource development model, and I think that sharing information, knowledge and ideas is the best way of working in software development. Still I think that being hired for proprietary software development must not be demonized. Of course, as there's a no reward in terms of sharing there must be a bigger reward in terms of money (i.e. I surrender all my rights for cash). It may happen that one gets hired piecework, for a single project: in this case one is more vulnerable to dishonest employers. This didn't happen to me personally, but some friends of mine had bad experiences, and lost a lot of time without being fairly retributed. Of course a contract should protect both parts. But contracts can be very generic in the specification. Software is not anything but a palpable good! Besides I don't think that contracts can distinguish between a well written software and a poorly written one. Note also that, in this (nasty) spirit, it's also likely that the employer cannot trust the employee! So also the employer should be protected by a dishonest employee). My question is the following: Which is, in your opinion, a good way of avoiding this kind of situation from the technical perspective?

  • Why is the remove function not working for hashmaps? [migrated]

    - by John Marston
    I am working on a simple project that obtains data from an input file, gets what it needs and prints it to a file. I am basically getting word frequency so each key is a string and the value is its frequency in the document. The problem however, is that I need to print out these values to a file in descending order of frequency. After making my hashmap, this is the part of my program that sorts it and writes it to a file. //Hashmap I create Map<String, Integer> map = new ConcurrentHashMap<String, Integer>(); //function to sort hashmap while (map.isEmpty() == false){ for (Entry<String, Integer> entry: map.entrySet()){ if (entry.getValue() > valueMax){ max = entry.getKey(); System.out.println("max: " + max); valueMax = entry.getValue(); System.out.println("value: " + valueMax); } } map.remove(max); out.write(max + "\t" + valueMax + "\n"); System.out.println(max + "\t" + valueMax); } When I run this i get: t 9 t 9 t 9 t 9 t 9 .... so it appears the remove function is not working as it keeps getting the same value. I'm thinking i have an issue with a scope rule or I just don't understand hashmaps very well. If anyone knows of a better way to sort a hashmap and print it, I would welcome a suggestion. thanks

  • The authenticity of host “host” can't be established

    - by Candroid
    I'm running a web app on a Linux server which connects to other servers. When I run the project on my Play framework on loclhost it runs fluently. When I run it on my Linux server I get the above message 3 times, one for each server. I read a post about it where it says that it is a man in the middle warning and if I write yes it should work. But though a write yes, nothing happens and the app doesn't run, and the error message keeps popping up. I tried creating private and public keys and add them to the authorized_keys file, but it didn't work either. What should I so to run my app?

  • Programming ... where to start?

    - by agnesb
    For the last 4 months, I've working tirelessly on a project with my partner, who is a super programmer. He did 100% of the whole mechanism that makes our site work. My job is to take care of the cosmetic aspects of the site ... thus I should say I am good enough at CSS and html. However, since we are using Drupal to build our site, from time to time, I need his help in order to figure out how to do the customization. Sometimes, I got frustrated. I know that as a partner, I should know a little bit on how to program. However, during the crunch time when you have to deliver lightning fast (we have our site built from scratch to finish in 4 weeks ... and you are all welcome to come join the fun! It's a site for programmers!) there is no time to learn from the basics. All I can do is to pick up whatever I need at the moment. Now the site is launched, I am thinking it should be time to do some learning. So, where should I start? My partner always said I need to start with Python. What's your take on this? Thanks.

  • Can I legally make a free clone of a game and use the same name? [closed]

    - by BlueMonkMN
    I gather from Is it legally possible to make a clone of the game? and How closely can a game resemble another game without legal problems that I should not try to profit from a clone if it is using the same assets, and, I presume, the same name. My question is whether it's legal to make a game like "Set" or "Catch Phrase", using the same name, and release it for free. What would I be risking if I did so -- just a take down notice, or could there be financial risk too? Edit: I guess my real question is whether the legal freedom is greater for a free game than one that is trying to make a profit. I just want a version of the game I can play remotely. Edit 2: I don't understand why this is being considered off-topic. I read the FAQ and it says it'S OK to ask questions about project management, which includes Publishing. And naming a game is a key aspect to publishing. That's what my question is about - choosing a legal name for my game with the consideration that I might post/publish it.

  • Vim not restoring screen contents on Debian?

    - by peu ping
    I always thought Vim restored the previous contents of the screen upon closing. This allows me to remember what commands I was typing previously and what I wanted to do next. Recently I've been using Debian 6 and Ubuntu (CLIs only) in a VM for a development project and I've been extremely annoyed with how Vim is operating. After I close the file its contents stay on the screen making me second guess whether I'm still in Vim or not, and having to use history to find out what I typed previously. I've been unable to find any solution. Using tput smcup and rmcup for instance does absolutely nothing.

  • Web-Service: How much would you charge? [closed]

    - by jacksbox
    I´ve to make an offer to a client who wants me to develope a web-service for him. I have some trouble calculating the pricing - can you help me? Here is a rough outline of the project: It´s a portal on which various artists and entertainers can register and administrate there profile (texts, gallerie, some embedded videos, choose categories and radius of offer, etc). Other user can browse the artists by 3-4 level categories and countries/staats. If someone wants to hire a artists, he can put them in an "shopping-basket" and can mail everyone in his basket. The Artists can answer them with a form on the website (he doesn't get the email of the other person). Users should be able to comment/rate the artists. But if an artists wants this comments/ratings visible on his profile he must pay, and after that, the admin of the site must activate this comments/ratings. So, no more information given, what would you charge (ca.)? Edit: It´ll be developed with php/codeigniter. A .psd design is already there.

  • Should I be worrying about limiting the number of textures in my game?

    - by Donutz
    I am working on a GUI in XNA 4.0 at the moment. (Before you point out that there are many GUIs already in existance, this is as much a learning exercise as a practical project). As you may know, controls and dialogs in Windows actually consist of a number of system-level windows. For instance, a dialog box may consist of a window for the whole dialog, a child window for the client area, another window (barely showing) for the frame, and so on. This makes detecting mouse hits and doing clipping relatively easy. I'd like to design my XNA GUI along the same lines, but using overlapping Textures instead of windows obviously. My question (yes, there's actually a question in this drivel) is: am I at risk of adversely affecting game performance and/or running low in resources if I get too nuts with the creating of many small textures? I haven't been able to find much information on how resource-tight the XNA environment actually is. I grew up in the days of 64K ram so I'm used to obsessing about resources and optimization. Anyway, any feedback appreciated.

  • Apache Alias - Chiliproject

    - by asdz
    I'm trying to setup Chiliproject (a ruby application for project management) I have setup my Apache already. However I want the Chiliproject to be like http://abc.com/Chiliproject as I want the abc.com to be used for other application. Following is my Chiliproject vhost setting: ServerName abc.com DocumentRoot /var/www/chiliproject/public Alias /chiliproject /var/www/chiliproject/public Options -MultiViews AllowOverride all When I go to abc.com, the Chiliproject page will appear but when I go to abc.com/chiliproject, I will reach the 404 page not found instead. If I change the DocumentRoot to /var/www, the page abc.com will be what I want, but the abc.com/chiliproject will comes to the 'Directory view' of my page.

  • How to use filegroups for DB split?

    - by Robin Jain
    In my project I have one DB used for everything. I want it to break into two databases. Static tables having look up values are to be stored in one DB and another DB would be having tables with dynamic data. My problem is that how would I use foreign key constraint in between those two DBs. Can someone help me out and suggest a way to proceed, better if I'm provided an example for the same. I thought of using synonyms for tables and then constraints on synonyms. but later I came to know that synonyms couldn't be used for constraints. I need to maintain relationships among the tables from both DB as the issue is with update, with a new release I just want to update look up tables and for the same I want to split my DB. I want to know how FileGroups could be used for this.

  • Top down or bottom up approach?

    - by george_zakharov
    this is the closest I think I can get to define my problem. I'm an interface designer and now I'm working with a team of programmers to develop a new CMS for a heavy media site. I'm sorry if it's a very, very dumb question to ask here, but I really need some help. As I've started developing a specification list for a prototype it turned out a very big one. I do realize now that the client-side will be JS heavy, with lots of DnD and other "cool designer stuff". The CMS will even include a small project management system for its users, nothing big like Basecamp, but with a live feed of comments etc. The problem is the the team has now separated. Someone is proposing the existing backend solution used in other CMS, someone is proposing to rewrite everything from scratch. The point to keep the code is that it is faster, the point to rewrite is to make it better for the proposed design (include Node.js and other stuff I don't actually get). The question is — can the UI specs influence back-end? The guys that propose to use the existing solution did everything with the Yii framework (as far as I know), and they say that everything on server is not affected by this "interface coolness". Others say that it does, that even autosave can't work without server load. Please, if this is really incomprehensible, again, I'm sorry, and I'll happy to clarify it after your questions. Thanks in advance

  • Is it possible to create a full "encrypted worried about privacy" VPS, but still being externally us

    - by Somebody still uses you MS-DOS
    I've been reading a lot of things about privacy, "being in control of your data" and everything, and now a project called diaspora* is trying to be an OSS Facebook alternative. Fact is: you still have to use a server. Even if you use a VPS somewhere, they still have access do your data, so diaspora* isn't that protective shell people are looking for absolute power over your data unless you create a server on your basement. My question is: is it possible to create a really encrypted usable server using a VPS? From database to source files? If not, what it can be "obfuscated" or encrypted? (And just a mention, not really my question, do you think is diaspora* really possible to be made?) (I know if you really want privacy you shouldn't be even using these services and being social, but I'm asking if it's possible to at least avoid companies using your data)

  • Unable to run Django on Mac OS X

    - by cybervaldez
    I'm working with a Django project on my Mac (running Leopard) and I want to show it to my team. I've already passed the neccessary port forwards from my router to my Mac's LAN IP address but it doesn't work. I've also tried running the XAMPP server since that always worked with my Windows XP computer but it still doesn't work. Whenever I type my > it's showing a Page Load Error. Is this possibly an issue with an Mac OS X configuration that I need to setup first to allow my port forwards to get in? It's my first time to do this with Mac, perhaps I need to configure something else in network preferences?

  • Recommended Free DNS hosting for my webserve on a dynamic IP? [closed]

    - by JSchwartz
    I have finished a webserver project (for school) and the professor wants to be able to "test it" from home whenever he is free - this means I need to provide his with the URL to my webserver (which is fine). The only issue is that my IP-Address is dynamic (changes almost everyday) and I would rather not have to email him everytime - nor do I want him to try when it isn't working ... So I was looking into alternative solutions like DNS hosting (I hope that is the right terminology), so I could provide something static for him to connect to ... problem is I have never done this before... Are there any recommeneded free ones? Does Google or someone provide something good? I found http://www.no-ip.com/ which seems like it does what I want... Any feedback would be appreciated. Thanks,

  • When you’re on a high, start something big

    - by BuckWoody
    Most days are pretty average – we have some highs, some lows, and just regular old work to do. But some days the sun is shining, your co-workers are especially nice, and everything just falls into place. You really *enjoy* what you do. Don’t let that moment pass. All of us have “big” projects that we need to tackle. Things that are going to take a long time, and a lot of money. Those kinds of data projects take a LOT of planning, and many times we put that off just to get to the day’s work. I’ve found that the “high” moments are the perfect time to take on these big projects. I’m more focused, and more importantly, more positive. And as the quote goes, “whether you think you can or you think you can’t, you’re probably right.” You’ll find a way to make it happen if you’re in a positive mood. Now – having those “great days” is actually something you can influence, but I’ll save that topic for a future post. I have a project to work on. :) Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Should I Open Source? [closed]

    - by Howdy_McGee
    My company recently created a full javascript, html & css Virtual Tour. Since it is html based there is no real way of securing our information/code so selling it could be flimsy. We are an extremely small company, barely on the map so I was thinking that by making this an open source project it could give us a chance to jump start our SEO by page views alone, especially if we provide documentation. Not to mention hopefully bring a community following on our blog. On the other hand though could this possibly hurt our sales as a web development company? If we are handing out this cool "plugin" we made what keeps people from making it commercial somehow? So I'm trying to weigh the options on whether I should make this Open Source or not and the pros / cons of each especially for a small business. What do you guys think about making things Open Source? How do I know if this product is the right thing to make Open Source? What are some pros and cons to going Open Source?

  • Which is the best way to catch an expiring domain name? [closed]

    - by newspeak
    I know a similar question has been asked, but I really don't know what to do. There is this .com domain which is currently on redemption period and should likely be available again within a month. I was wondering which is the best way to get it at a reasonable price. I don't think it's a highly valuable domain, it shows to have very bad ranking and has 0 exact same searches according to adwords. Why it is valuable to me is very simple: I have a project responding to this name. I already own the .net domain and would love to have the .com. I discovered the domain was going to be available thanks to an email I received by a backorder site. I did some research and these guys have a bad reputation on the web. I did further research and found that more reputable (at least in theory) companies should be the likes of snapnames, pool, namejet, godaddy, etc. I am a bit suspicious using these drop cathing services: What if they shill bids? What if they make it go into auction even if I'm the only person interested? What if I raise attention and interest to the domain by backordering? I just would rather wait for it to be deleted and available again to register it manually. It is really not an interesting domain name, and I don't think anyone would care to have it. But what if the domain is already being watched by the domain industry sharks? I did a whois research and my desired domain nameserves point to domcollect.com, which appears to be an auction site. What if I decide to wait for manual registration and I miss the chance to get it? I'm willing to spend the 60/70$ fees these sites require, but not really more than that. Suggestions? Thank you very much. I'm a bit confused and undecided.

  • How come there is still so much programming work?

    - by jd_505
    I wonder why programming jobs haven't yet "dried up" because of the software evolution, for example, I am a developer myself, which means that I do care about software (I mean I am not of the type of guys that needs a computer mainly to just browse the Internet), and still I wouldn't mind if I never receive any more updates on my Ubuntu machine. I find that it provides everything I need, and while the updates provide various bug fixes/improvements, I wouldn't mind using it with its current state for the rest of my life, for 2 years of Ubuntu usage I have never bumped at a serious bug/problem. Another example is Windows, almost half of it's users still use XP, which is practically ancient, yet they find it satisfying all their needs (and I agree with them). I could go with many more examples, but by now you are understanding my point and my question. While new "trends" appears all of the time (like a new mobile OS) which runs on new platforms and requires some fresh development work, still the majority of the software effort goes in to what I consider as "completed projects", or at least a state of a project which is enough to be considered as completed. Do you have an explanation? I can't think of the right tags for this question; please edit it the way you find it to be most appropriate.

  • Why can't I change the icon being displayed for a desktop shortcut?

    - by Bill
    I wanted to change the icon showing for a shortcut on the desktop, which points to a .Net utility I created for myself. I rebuilt the exe after changing the icon used within the project. In Windows Explorer the new icon shows in all size variations for the exe. In the 'Change Icon' dialog from the Properties option, the correct icon is showing as present, yet when I Apply it remains with the old icon??? Even when I delete the shortcut and create a new one pointing to the newly built exe the old icon somehow is assigned???

  • Is it possible/likely to be paid fairly without a college degree? [closed]

    - by user20134
    Some back story, and then my question: I took a "break" from getting a university education last year to work full time as back end developer on a GIS application at $10.50 an hour. Later that year I was hired on by a fairly prestigious organization on their GIS application for a meager salary + rockin' benefits (not that I need them). I agreed to work on this project through Summer 2012. I don't feel like I'm being fairly compensated for my time. Other team members make between 3-5 times as much as I do, and their work isn't 3-5 times as good as mine, nor do they have 3-5 times as much output. I don't think this is a rectifiable situation within this institution. They've got a set of personnel charts and the way it gets computed, I make less money than any of the janitors (who are very good, and very nice people to boot, and I'm glad they get paid so well. I wish everyone got livable wages). I'm pretty bright, but school's a drag. I don't want mega bucks, I just want $40k/yr (localized to the southeast united states) so I can save enough money to travel, or maybe "finish [my] education". My question is this: Are people without degrees ever compensated commensurate with other people who have degrees? As a someone who never "finished their education", how badly do you think this as hurt you? How do you navigate the job seeking and hiring process? As someone who hires programmers, do you pay more for diplomas? Is that an institutional necessity, or based on your own value judgement?

  • reaching 99.9999% uptime

    - by christopher-mccann
    I am currently developing a project which is mission-critical. The actual domain name is registered with 1 & 1 and I plan on purchasing DynDNS Custom DNS service (which has 5 different geographical locations for DNS) and then another secondary DNS service to make sure my DNS is as failover safe as possible. Does it matter that the registration is with 1 & 1 - are they a weak link in the chain? All I really use them for is to say that DynDNS is my primary DNS nameserver and then my secondary DNS is my other nameserver. I can transfer the registration to DynDNS - Im just not sure if it really matters or not. Thanks

  • How to handle class dependency with interfaces and implementatons

    - by lealand
    I'm using ObjectAid with Eclipse to generate UML class diagrams for my latest Java project, and I currently have a handful of situations like this, where I have a dependency between two interfaces, as well as one of the implementations of one of the interfaces. Here, foo is the graphics library I'm using. In the previous example, FooCanvas draws ITexture objects to the screen, and both FooCanvas and its interface, ICanvas, take ITexture objects as arguments to their methods. The method in the canvas classes which cause this dependency is the following: void drawTexture(ITexture texture, float x, float y); Additionally, I tried a variation on the method signature using Java's generics: <T extends ITexture> void drawTexture(T texture, float x, float y); The result of this was a class diagram where the only dependencies where between the interfaces and the implementing classes, and no dependency by a canvas object on a texture. I'm not sure if this is more ideal or not. Is the dependency of both the interface and implementation on another interface an expected pattern, or is it typical and/or possible to keep the implementation 'isolated' from its interfaces dependencies? Or is the generic method the ideal solution?
