  • How to create a GLib.TimeVal from timestamp?

    - by fluteflute
    I have a value such as 'timestamp' below, where the last three digits correspond to milliseconds. timestamp = 1340830988768 I currently have code that looks like the following: import indicate indicator = indicate.Indicator() indicator.set_property_time("time", int(timestamp[:-3])) I want to amend it to use: from gi.repository import Indicate indicator = Indicate.Indicator() However, the new version of set_property_time requires the second parameter to be a GLib.TimeVal. How do I create a GLib.TimeVal from my timestamp? Millisecond precision is not important for this application.

  • Software vs Network Engineer (Salary, Difficulty, Learning, Happiness)

    - by B Z
    What are your thoughts on being a Software Engineer vs a Network Engineer? I've been on the software field for almost 10 years now and although I still have a great deal of fun (and challenges), I am starting to think it could be better on the "other" side. Not to degrade network engineers (i know there are many great ones out there), it seems (in general) their job is easier, the learning curve from average to good is not as steep, job is less stressful and pay is better on average. I think as software developer I could make the switch to networking and still enjoy working with computers and feel productive. I spend an enormous amount of time learning about software, practices, new technologies, new patters, etc...I think I could spend a much smaller amount of time learning about networking and be just as "good". What are your thoughts? EDIT: This is not about making easy money. Networking and Software are closely related, I love computers and programming, but if I can work with both, make more money and have less stress in my life and can spend more time with my family, then I am willing to consider a change and hence I am looking for advice that Do or Don't support this view.

  • Why do the GNOME symbolic icons appear darker in a running application?

    - by David Planella
    I'm creating an application that uses symbolic icons from the default theme. However, there are a few icons that I need that cannot be represented by those from the default theme, so I'm creating my own ones. What I did was to simply go to /usr/share/icons/gnome/scalable/actions/, copied a few locally into my app's source tree that could serve as a basis, and started editing them. So far so good. But I've noticed the following: all symbolic icons are of a light grey color when looking at the original .svg file, but when they are put onto a widget, they become darker. Here's an example, using the /usr/share/icons/gnome/scalable/actions/view-refresh-symbolic.svg icon from the default theme: Here's what it looks like when opening the original with Inkscape: And here's what it looks like on a toolbar on a running application: Notice the icon being much darker at runtime. That happens both with the Ambiance and Radiance themes. I wouldn't mind much, but I noticed it affects my custom icon, whereby parts of it become darker (the inner fill), whereas parts of it remain the same color as the original (the stroke). So what causes the default symbolic icons to darken and how should implement that for my custom icons?

  • Interfacing the payment systems

    - by etranger
    Hello all. I'm a complete newbie to using online payment systems for web projects, and can't really think of where to start. Let's assume that web system in question needs to generate some income online, and the business idea/functionality is in place, while organizing cash flow is the only unsolved problem. Points of interest are how the custom developed software interfaces to payment systems, and how the resulting income is available to the owner. I do understand that there are probably hundreds of systems out there, but to be more specific on which of them suit, I'd have to know how they work, and that's where I don't feel like understanding much. Thanks in advance.

  • Online Poker Game Programming

    - by Eyal
    I am trying to write a massive online multiplayer client for a poker site, where one user can be on a Flash client and the other on say an iOS client (iPhone / iPad), and would like to know how can interaction between two users be visible on both clients. What would be better to use? Should I use MSMQ? AJAX? Something other? I need the messaging layer (client interaction messages) to scale up to 100K+ online users to begin with. In other words; What scalable technology can I use to make game interactions between online users visible to all game participants?

  • How In-Memory Database Objects Affect Database Design: Hybrid Code

    - by drsql
    In my first attempts at building my code, I strictly went with either native or on-disk code. I specifically wrote the on-disk code to only use features that worked in-memory. This lead to one majorly silly bit of code, used to create system assigned key values. How would I create a customer number that was unique. We can’t use the Max(value) + 1 approach because it will be very hideous with MVCC isolation levels, since 100 connections might see the same value, leading to lots of duplication. You...(read more)

  • How do you stop yourself from programming?

    - by dan
    Lately I've started earning enough off my software to not have to do consulting to support myself. So I work full time designing and writing my own software products. The problem is that there are no boundaries between my work and my life any more. When I mostly did consulting, I was weary enough of work at the end of the workday to go home and do other things. But now, I sit down to program in the morning, and before I know it it's 11pm and I'm still writing software and not bored or tired at all. I have to force myself to go to sleep. I feel happy and fulfilled, but objectively, I know I need more balance and variety in my life. Any tips or suggestions on how to pull yourself away from the console?

  • How do I get my programs to communicate with each other

    - by Benjamin Lindqvist
    I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

  • Learning Programming from scratch

    - by David542
    I am entirely new to programming, other than basic HTML/CSS knowledge. I want to learn programming as quickly and efficiently as possible, and I'm willing to put in the time (at least 70 hours a week). The reason I want to learn is because I have a startup that I've written a business plan for and have prototyped in Photoshop (both front-end and back-end pages). My goals is to have a prototype of the site up within 6 months. I have a good aptitude for math (A's in all math courses up through DiffEq and Linear Algebra). I assume learning programming from scratch can be a daunting task -- not because it is particularly difficult, but because there are so many areas and so much information. I want to make sure that I learn as efficiently as possible and have individuals (in addition to Google) to solicit advice from and that will help me when I get stuck or have questions. I know with other's help, my learning experience will be both more productive and enjoyable. What is the best way to find people that will help me in this? What are some good 'live' resources in addition to asking questions on Stack Overflow? Thank you very much for your time and help.

  • How should I describe the process of learning someone else's code? (In an invoicing situation.)

    - by MattyG
    I have a contract to upgrade some in-house software for a large company. The company has requested multiple feature additions and a few bug fixes. This is my first freelance style job. First, I needed to become familiar with how the application worked - I learnt it as if I was a user. Next, I had to learn how the software worked. I started with broad concepts, and then narrowed down into necessary detail before working on each bug fix and feature. At least at the start of the project, it took me a lot longer to learn the existing code than it did to write the additional features. How can I describe the process of learning the existing code on the invoice? (This part of the company usually does things in-house, so doesn't have much experience dealing with software contractors like me, and I fear they may not understand the overhead of learning someone else's code). I don't want to just tack the learning time onto the actual feature upgrade, because in some cases this would make a 'simple task' look like it took me way too long. I want break the invoice into relevant steps, and communicate that I'm charging for the large overhead of learning someone else's code before being able to add my own to it. Is there a standard way of describing this sort of activity when billing for a job?

  • Is it a must to focus on one specific IT subject to be succesful?

    - by Ahmet Yildirim
    Lately I'm deeply disturbed by the thought that I'm still not devoted to one specific IT subject after so many years of doing it as a hobby. I've been in so many different IT related hobbies since I was 12. I have spent 8 years and now I'm 20 and just finished freshman year at Computer Eng. Just to summarize the variety: 3D Game Dev. and Modelling (Acknex, Irrlicht , OpenGL, GLES, 3DSMAX) Mobile App.Dev (Symbian, Maemo, Android) Electronis (Arduino) Web.Dev. (PHP, MYSQL, Javascript, Jquery, RaphaelJS, Canvas, Flash etc.) Computer Vision (OpenCV) I need to start making money. But I'm having problem to pick the correct IT business to do so. Is it a problem to have interest in so many different IT subjects?(in business world) I'm having a lot of fun by doing all those stuff from time to time. Other than making money I also noticed that having so many different interests is lowering my productivity. But I'm still having difficulty to pick one. I'm feeling close to all those subjects (time to time).

  • What is the most efficient way to study multiple languages, frameworks, and APIs as a developer?

    - by Akromyk
    I know there are those out there who have read a slurry of books on a specific technology and only code in that one particular language, but this question is aimed at those who need bounce around between using multiple technologies and yet still manage to be productive. What is the most efficient way to study multiple languages, frameworks, and APIs as a developer without becoming a cheap swiss army knife? And how much time should one dedicate to a particular subject before moving to another?

  • Language-independent sources on collision detection

    - by Phazyck
    While making a Pong clone with a friend, we had to implement some collision detection. For research purposes, my friend dug up a book called "AdvancED Game Design with Flash" by Rex Van Der Spuy. This book was clearly targeted at implementing collision detection in ActionScript, and I also have some problems with how the concepts are presented, e.g. presenting one method as better than another, without explaining that decision. Can anyone recommend some good material on collision detection? I'd prefer it if kept the implementation details as language-independent as possible, e.g. by implementing the concepts in pseudo-code. Language-specific materials are not completely unwelcome though, though I'd prefer those to be in either Java, C#, F# or Python or similar languages, as those are the ones I'm most familiar with. :-) Lastly, is there perhaps widely known and used book on collision detection that most people should know about, like a 'the book on collision detection'?

  • Will high reputation in Stack Overflow help to get a good job?

    - by Shamim Hafiz
    In a post, Joel Spolsky mentioned that 5 digit StackOverflow reputation can help you to earn a job paying $100k+. How much of that is real? Would anyone like to share their success in getting high paid job by virtue of their reputations on StackExchange sites? I read somewhere that, a person got Interview offer in Google because a recruiter found his Stackoverflow reputation to be impressive. Anyone else with similar stories?

  • Listing technologies on a resume for a software position when your background is game programming?

    - by Ford
    So I'm thinking about applying for a entry level position in the software industry but my limited experience working and all my notable experience in college is with game technologies. Sure, the languages transfer over well but most of the technologies I have experience with are all related to graphics programming, engines of various types, and such, and do not transfer over at all. I feel like it would be inappropriate to just take my game programming resume and basically replace the word game with software for the reasons mentioned but on the other hand if I take them out I will only have languages and some technologies that I have some small passing experience with- which will obviously not reflect well on me. Should I leave them out or put them in, and if so how can I spin them to be appropriate?

  • Lead/Manager vs Individual contributor which is better?

    - by User11091981
    Currently I am working in a company as a Manager (software dev). But I only have 6.8 yrs experience. I joined this company as a software engineer and got promoted to SSE, Lead and Manager. Some of my team members are having better experience than me, and I feel like I need to have more exposure/experience to take these roles. I feel like it is better to be an individual contributor learn many things for another couple of years and become a Principal Software Engineer, rather than involving in Management. Options I have: 1. Ask my current employer to make me an individual contributor? 2. Find a new company and join as an SSE to start over? 3. Find a new company for a lead position? Please advice.

  • How does session middleware generally verify browser sessions?

    - by BBnyc
    I've been using session middleware to build web apps for years: from PHP's built-in session handling layer to node's connect session middleware. However, I've never tried (or needed) to roll my own session handling layer. How would one go about it? What sort of checks are necessary to provide at least some modicum of security against HTTP session highjacking? I figure setting a cookie with a token to keep track of the session, and then perhaps some check to see that the originating IP address of the session doesn't change and that the client browser software remains consistent. Hoping to hear about current best-practices...

  • Utility Queries–Database Files, (and Filegroups)

    - by drsql
    It has been a while since I last posted a utility query, and today, to avoid other work I am supposed to be doing, I decided to go ahead and work on another post.  Today, I went ahead and worked on a server configuration type query. One query I find I use pretty often is the following one that lists the files in the database. In this blog I will include 3 queries.  The first will deal with files and databases, and the second runs in a database to see the files and their filegroups (If there...(read more)

  • Involving kids into programing - which language? [closed]

    - by boj
    Possible Duplicate: What are some good tools for introducing kids to programming? Long-long time ago I had a great book by Frank DaCosta about writing adventure games in Basic, it had a great influence on me. I would like to show the world of programming to my child too but I have two problems: I can not found books like DaCosta's (but we can replace it with our fantasy so not a big deal) Which programming language should I use? Small Basic?

  • Application won't run when installed in "/opt"

    - by Sam Hewitt
    I've developed a program for the App Developer Showdown, with quickly, in python, and it works as expected when I package and install it normally -in /usr. However when packaged for installation in /opt it doesn't run -and I'm not getting (or can't find) an error message of any sort, as to what the problem might be. I was wondering if someone here has the answer. The app does require root access -using gksudo- to function. I'm fairly new to programming, but not to Linux.

  • Ubuntu App Submission won't allow the "free" bubble to be checked

    - by Compt
    I am at the final stages of the Ubuntu App Developer Showdown, and I'm right at the point where I am submitting my app. The problem I run in to however, is that even though buy is at $0.00, it will not allow me to click on the "free" button, and keep that configuration saved. So when I go to "preview your app", it shows it saying "USD $0.00 ---- Buy" instead of saying "Free ---- Install". So I was wondering if it makes any difference or not.

  • Crappy school, what to do? [closed]

    - by zhenka
    I started programming fairly late. I am 24 years old and about to graduate from a local public university with a really poorly designed curriculum and teachers. Most of the work felt like busy work, and no matter how much I try, it all feels like a waste. I know what a good curriculum looks like. I know what books I should read, but alas it's not so in my university. There is no way at this point that I can catch up to those graduating from places like MIT. My question and this is a serious one: what do I do? Do I just postpone learning the theory I would have learned until later and focus on software engineering skills? How important is the theory in terms of landing a job in New York? Any particular things I should focus on to land a software engineer job? I am very motivated and I just wish someone would give me the time and a chance.

  • Is it costly to leave the Console and Script features enabled in Firebug?

    - by parisminton
    For some time now, I've run Firebug constantly enabled to do quick DOM inspections, leaving the Console and Script panels disabled. I'm just starting to use these two features so I don't have to keep using alerts for testing and debugging. I enable them while I use them and turn them back off when I'm done. I'd like to know if these particular features can slow things down such that they shouldn't be left on round-the-clock. Like do they slow down page loads, use inordinate chunks of memory or something? I don't see anything about it in the Firebug wiki.
