• New Job Over Budget

  - by moneylotion

  I recently started a new job as a contract developer, and my non-developer boss of about two weeks ago gave me the task to re-create an app from another language and developer that he will reuse with multiple clients (replacing the front-end), that I estimated would take longer than his estimate of 12 hours. Two weeks later, I'm 230% over-budget. I admit this was my 2nd web app, I had been a wordpress developer in the past, so I am somewhat new to code igniter, but not shabby php by any means. My boss hired me knowing this and I was clear that it would take longer than his 12 hours. He's seen me in the office on task for 2 weeks, he should be somewhat prepared for this bill. Do I expect the full amount of hours, or do I filter against how much of learned? Can I bill for research as a developer?

• DBA Best Practices: A Blog Series

  - by Argenis

    Introduction After the success of the “Demystifying DBA Best Practices” Pre-Conference that my good friend Robert Davis, a.k.a. SQLSoldier [Blog|Twitter] and I delivered at multiple events, including the PASS Summit 2012, I have decided to blog about some of the topics discussed at the Pre-Con. My thanks go to Robert for agreeing to share this content with the larger SQL Server community. This will be a rather lengthy blog series - and as in the Pre-Con, I expect a lot of interaction and feedback. Make sure you throw in your two cents in the comments section of every blog post. First topic that I’ll be discussing in this blog series: The thing of utmost importance for any Database Administrator: the data. Let’s discuss the importance of backups and a solid restore strategy. Care to share your thoughts on this subject in the comments section below?

• Is it OK to push my code to GitHub while it is still in early development?

  - by marco-fiset

  I have some projects that are in a very early development state. They are nowhere nearing completion but I do host them (as public repos) on GitHub because: I have multiple computers and I want access to my code everywhere I want a backup for my code I want it to be easy if someone wants to collaborate in some way I use GitHub Issues as a poor man's project management software Is it OK to publish a project on GitHub even when it is very early in the development? I am a bit concerned about someone to come by and say OMG this is total BS, this code is so bad! while looking at unpolished/still in development/not tested code. What are your practices when you start new public projects? Do you wait until you have something substantial to show or you create a bare repo directly on GitHub and start from there? I used GitHub throughout this post but this applies to every code hosting service out there.

• VMMap - awesome memory analysis tool

  VMMap is a process virtual and physical memory analysis utility. It shows a breakdown of a process's committed virtual memory types as well as the amount of physical memory (working set) assigned by the operating system to those types. Besides graphical representations of memory usage, VMMap also shows summary information and a detailed process memory map. Powerful filtering and refresh capabilities allow you to identify the sources of process memory usage and the memory cost of application features. Besides flexible views for analyzing live processes, VMMap supports the export of data in multiple forms, including a native format that preserves all the information so that you can load back in. It also includes command-line options that enable scripting scenarios. VMMap is the ideal tool for developers wanting to understand and optimize their application's memory resource usage. span.fullpost {display:none;}

• Is there a pattern or logical structure I can follow for Event Log Numbers?

  - by makerofthings7

  What are some ideas or structure I can use when assigning EventID to events that will be saved to the Event Log? Some options I've considered Sequential (0... int.Max) Multiple of 10, where the "0" is replaced with how noisy the debugLevel is set. xxx0 may represent exceptions, critical information, start, stop etc. ...? What numbering approach gives you the most insight when a user describes the event in an email or phone? What is the most useful to support staff?

• Requirement, architecture data capture tool

  - by Deno

  Are there any tools available for the following use case: I am planning to write a complex application and now I just know about the basic functional requirments. I am refining the functionality with more and more details. I am also writing down how to implement this in software architecture perspective. I am in a situation where there are multiple ways implement a certain functionality and based on the selected approach, other parts of the program will also change. At this moment, I don't want to decide on the approach to use, I just want to list down all the options, present to a wider audience and get it finalized. Are there any standard software tools to do this? I know I can use MS excel or some mind mapper tools, but just thinking of some standard tools (not just for programmers, but for managers and other) availability Thanks, Den

• How to handle "porting" software that's still in development

  - by BAM

  My company is building an iOS version of an Android app that our client is developing (but has not yet released). We have access to the latest builds and source, however since the software is frequently re-structured and refactored, we're doing a lot of unnecessary re-work. In addition, the due date on the contract will likely be passed before the client's application is even ready for release. In other words, we're supposed to build the iOS version before the original Android version is even complete. Luckily the client tossed out the original deadline, but now we may have to renegotiate pricing... never a fun situation. Are we handling this incorrectly? How are "ports" (especially between mobile platforms) normally done? Is there a correct way to pipeline development for multiple platforms without so much re-work? Thanks in advance! :)

• VirtualBox Port Forward

  - by john.graves(at)oracle.com

  A great new feature in VirtualBox 4.0 is the ability to use NAT networking and forward ports without needing to use ssh -L/-R tricks.  This is great for booting multiple VM domains simultaneously.  It is possible to have several instances which map back to the host machine and different ports on localhost:* automatically forward to the correct VM.  This avoids the hassle of setting up dns entries or static IP addresses.In this example, I'm mapping the host ports 3xxxx to the VM's well known server ports.Note: It is important to setup the Frontend HTTP host/port to avoid incorrect URL rewriting.You may also need to setup an http channel to deal with local traffic which uses the network address 10.0.2.15Happy VMing.

• specifying an object type at runtime

  - by lapin

  I've written a Vbo template class to work with opengl. I'd like to set the type from a config file at runtime. e.g. <vbo type="bump_vt" ... /> Vbo* pVbo = new Vbo(bump_vt, ...); Is there some way I can do this without a large if else block e.g. if( sType.compareTo("bump_vt") == 0 ) Vbo* pVbo = new Vbo(bump_vt, ...); else if ... I'm writing for multiple platforms in c++. thanks

• -webkit-linear-gradient Not working in Dreamweaver CS6

  - by Ken

  I've tried multiple times to apply the following piece of code in a CSS document: display: block; width: 500px; margin: 500px auto; padding: 15px; text-align: center; border: 4px solid blue; background: -webkit-linear-gradient(top,black,white); outline: 7px solid red; Everything appears correctly, except the gradient. I have CS6 Live View turned on, and it still refuses to appear. All I get in my box is a white background, as opposed to the black to white gradient. However, when I type the same line of code into the trial of Coda 2 I downloaded, it works perfectly. Is there anything I can do to resolve the issue?

• QotD: Eben Upton on Raspberry Pi Model B Shipping With 512MB of RAM

  - by $utils.escapeXML($entry.author)

  One of the most common suggestions we’ve heard since launch is that we should produce a more expensive “Model C” version of Raspberry Pi with extra RAM. This would be useful for people who want to use the Pi as a general-purpose computer, with multiple large applications running concurrently, and would enable some interesting embedded use cases (particularly using Java) which are slightly too heavyweight to fit comfortably in 256MB.The downside of this suggestion for us is that we’re very attached to $35 as our highest price point. With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard.Eben Upton, a founder and trustee of the Raspberry Pi foundation, in a blog post announcing the change.

• Adding a short delay between bullets

  - by Sun

  I'm having some trouble simulating bullets in my 2D shooter. I want similar mechanics to Megaman, where the user can hold down the shoot button and a continues stream of bullets are fired but with a slight delay. Currently, when the user fires a bullet in my game a get an almost laser like effect. Below is a screen shot of some bullets being fired while running and jumping. In my update method I have the following: if(gc.getInput().isKeyDown(Input.KEY_SPACE) ){ bullets.add(new Bullet(player.getPos().getX() + 30,player.getPos().getY() + 17)); } Then I simply iterate through the array list increasing its x value on each update. Moreover, pressing the shoot button (Space bar) creates multiple bullets instead of just creating one even though I am adding only one new bullet to my array list. What would be the best way to solve this problem?

• Why is not there a python compiler to native machine's code?

  - by user2986898

  As I understand, the cause of the speed difference between compiled languages and python is, that the first compiles code all way to the native machine's code, whereas python compiles to python bytecode, to be interpreted by the PVM. I see that this way python codes can be used on multiple operation system (at least in most cases), however I do not understand, why is not there an additional (and optional) compiler for python, which compiles the same way as traditional compilers. This would leave to the programmer to chose, which is more important to them; multiplatform executability or performance on native machine. In general; why are not there any languages which could be behave both as compiled and interpreted?

• How do global cancel/exit commands work in bash?

  - by SecurityGate

  As I have done multiple times before, I've written bash scripts, and just general commands that go nowhere. They just blink the little command line cursor at me for infinity until I control+C the command. When I do cancel the command, what exactly is going on when I do this? Am I somehow stopping and killing the current PID I'm working on? Does it jump to a different run-level and execute something to terminate the command? On a slightly different note, I've never been able to figure out how to set up something like this in a script or program I've worked on. Since I mostly program in Ruby, can I setup something like a certain key press stops the program? Every time I've looked into doing something similar, I always end up getting hung up when it comes to user input, whether that is a loop waiting for a condition, or something like this: def Break() user_break = gets.strip end def Main() Function1() Break() Function2() Break() [...] end It seems and is incredibly bulky, and definitely isn't easily scaled up or down.

• Where to put git "remote" repo on purely local git setup?

  - by Mittenchops

  I overwrote and lost some important scripts and would like to setup version control to protect my stuff. I've used git before, and am familiar with commands, but don't understand where I would put my "remote" repository on an install set up on my own machine---the place I push/pull to. I don't intend to share or access remotely, I just want a little source control for my files. I followed the instructions here for setting up my staging area: http://stackoverflow.com/questions/4249974/personal-git-repository But where do I put git "remote" repo on purely local git setup? How does the workflow work then? On the command in the above: git remote add origin ssh://myserver.com:/var/repos/my_repo.git Where should I put/name something like this? If I have multiple different projects, would they go in different places? I'm running 11.10.

• MySQLwith mutiple threads and processes

  - by Abhan

  I'm developing a telecom messaging platform in C, and I'm going to need multiple processes to be working with MySQL DB. How can I make two processes read/write to/from a Mysql DB and, if/when one of them goes down, get the other to seamlessly take over the work until the dead process gets back to work? I was thinking/googling some options and am stuck in place where I don't know which one to choose. What I think so far is that table lock is not the best option to go for, as it will stall the other process until the table is unlocked. The other option is to use row-level locks or manual locks, but I can't find the best way to do it.

• Amazon Kindle - Whispersync implementation?

  - by Bala

  For those who are not aware of Kindle's whispersync, here is how it works (from amazon.com): "...Whispersync synchronizes the bookmarks and furthest page read among devices registered to the same account. Whispersync is on by default to ensure a seamless reading experience for a book read across multiple Kindles." Can anyone give some details on how the Whispersync feature is implemented in Kindle and in the Backend of Amazon? I am guessing this implementation involves a very simple hashmap for each user account. Each hashmap maps Books with satellite information about the book. Satellite information contains bookmarks, furthest page read, device on which it was read, etc.. Thanks!

• How to Organize Subdirectories? [closed]

  - by Gary Iverson

  I am working on my first major (several hundred pages) website design and development project. I want to create subdirectories for each of the website's categories, which in turn have their own subdirectories for easy user navigation. Example: website.com/directory. I am aware that by placing an index.html file within each directory, the browser automatically detects and navigates to that page, but that seems like a messy solution (having multiple index.html files, albeit in distinct folders), and I cannot imagine everyone does that. So my question is...how do you properly organize and use subdirectories?

  Originally posted on: http://geekswithblogs.net/rodelljr/archive/2014/08/22/kc-java-users-group-presentation.aspxI would like to thank the KC Java Users Group for allowing me to do my presentation; Supporting Multiple Devices Part 2. In this talk, I discussed a Master/Detail application that runs on Android 2.2 devices and forward. I used the Actionbar compat Android library to allow the older devices to have an actionbar. I also used a SQLite database for my data. And just to add one last thing, I also incorporated the use of custom fonts. If you are interesting in looking at this sample application, I have uploaded it to my GitHub account here. I also have a Power Point presentation which you can get here.

• How to change the state of a singleton in runtime

  - by user34401

  Consider I am going to write a simple file based logger AppLogger to be used in my apps, ideally it should be a singleton so I can call it via public class AppLogger { public static String file = ".."; public void logToFile() { // Write to file } public static log(String s) { AppLogger.getInstance().logToFile(s); } } And to use it AppLogger::log("This is a log statement"); The problem is, what is the best time I should provide the value of file since it is a just a singleton? Or how to refactor the above code (or skip using singleton) so I can customize the log file path? (Assume I don't need to write to multiple at the same time) p.s. I know I can use library e.g. log4j, but consider it is just a design question, how to refactor the code above?

• Looking for PHP/MySQL-based ad manager

  - by user359650

  Could you recommend based on your experience a PHP/MySQL-based admin interface for managing your website ads? In order to be really useful, such application should have: -basic CRM functionality to track who is providing the ads -multilingual multi country support: have the ability to specify for the same ad, different versions for multiple languages/countries -predefined ad formats (google Ads, flash ads...) and sizes with corresponding PHP helpers so as to insert in the HTML code the necessary markup to properly integrate the ad. Ideally if that application could be desgined for Zend Framework that would be awesome (but I think I'm dreaming at this point).

• Is there a limit on the number of threads that can be spawned simultaneously?

  - by georgesl

  Yesterday I came across this question: How can i call robocopy within a python script to bulk copy multiple folders?, and I though it might be a good exercise for multithreading. I though of spawning as many threads as files needed to be copied, each routine having an exception handling system to prevent the whole copying process from crashing (and log -using mutex on the log file - if there was an error). My question: Is there a limit on the number of thread you can spawn almost simultaneously? If yes, what is the limiting factor? My question is focused on PC desktop, but I welcome any answer on different hardware (embedded systems, calculus clusters, etc.).
