• How (in terms of which parameters) is a "professional-grade" broadband connection different from a "consumer" one?

  - by odemarken

  By "professional" I mean here: The kind you can get at a datacenter for your server The kind you can get at an office that would be good enough for hosting web and mail server with low to medium traffic. (Please ignore other aspects of "the self-hosting problem" and focus only on broadband connection quality). Another way to frame this question would be "what parameters should office broadband have to compare to a datacenter-provided one for the purposes of self-hosting". The knowledge I have gathered so far is in answer format below.

• Outside of a web browser, does the Javascript programming language do anything? [closed]

  - by Stom

  I often hear people talking about Javascript in conjunction with web browser programming/web page programming and such, and/or form logic, etc. However, outside of a browser, can Javascript source be written and compiled to work outside of a browser, much like C/C++ can work in a terminal window/GUI window with a library? Can I write "Hello World" in Javascript in a console terminal on a modern OS GUI and such like C?

• In terms of load handling, which is better: one server or two of equivalent power?

  - by seldary

  My goal is to figure out if i'm better off with one strong server, or multiple weaker servers with a load balancer. Does the fact of splitting the load between servers have an effect on the total load my website could take? It's hard to single that out, because there are of course a lot of parameters that affect the results, so some assumptions: Putting failover considerations aside - I know it matters, but for the sake of the question's simplicity, lets assume nothing fails. The servers in the multiple servers option have an accumulated "power" equivalent to the one server option (about the same amount of cores and RAM space). If that is too theoretical, here is a concrete question that could help: Suppose I have several instances of exactly the same server - lets call it S. Suppose that server S can serve a load of up to X calls per time unit. Will two S servers with a load balancer serve 2X calls per time unit? significantly more? significantly less?

• How do i start Game programming in windows phone xna?

  - by Ankit Rathod

  Hello, I am very much interested in Game programming in Xna. However during my college days i did not take Physics or Maths. Does that mean i can't create games in xna? I just know basics of trignometry. Can you all point me to few links where i can learn xna as well as the basic stuff of Maths that is bound to be required in most of the games? Are all game programmers excellent in Maths and Physics ? Thanks in advance :)

• Programming in the United States Airforce - How hard to get a job doing it? [closed]

  - by Holland

  I already know how to program. Been at it for a year; the language I've worked mostly with has been C++, and I'm currently studying x86 assembly programming, with the goal to move towards ARM assembly after I've finished with that. Thus, given my experience and knowledge, I'm curious to know if any "vets" around here have had any excursions in the military doing software/electrical engineering, and how hard it would be to actually get a job doing it - with someone who already has previous experience and knowledge regarding that field, however slight. By definition of "hard", in this context, I suppose I'd be referring to the required knowledge to actually be a "shoe-in" for both low level and high level software/hardware applications. I know hex fairly well, and enough to convert that hex to binary. I also have an ok knowledge of algorithms, such as Binary Search Tree, Linked List, etc. Everything I've learned so far has been self taught for the most part.

• Do I need a degree in Computer Science to get a junior Programming job?

  - by t84

  Do I need to go to Uni to get a job as a Junior C# coder? I'm 26 and have been working in Games (Production) for 6 years and I am thinking of a change, I've had exposure to VB6, VBA, HTML, CSS, PHP, JavaScript over the past few years and did a web design NCFE at College, but other than that, nothing else! I'm teaching myself C# at the moment with books and I was wondering 'how much' I need to learn and also how I can improve my chances of getting a programming job! Am I a late started to learn coding? (I know many people who started at a very young age!) Thanks for the help :)

• Will learning ColdFusion help me advance my programming skills? [closed]

  - by chhantyal

  Currently I am working with a small web development company. We use jQuery on front-end, Coldfusion for back-end and MySQL as our database. We just started to use HTML5 and CSS3. This is my first internship and job. I know the basics of Python and want to add Django or Ruby on Rails on my skills set. In addition, I want to advance my programming skills with Machine Learning, Compilers, NoSQL and Unix Hacking. I also find front end web development pretty interesting. Should I focus on front-end and become skilled on HTML5/CSS3/Javascript? Or dive into back-end learning ColdFusion. I will probably leave the company after a year since I want to work with great product start-ups. And I live in India, where ColdFusion is not popular. Will learning ColdFusion help me become better programmer?

• What is the best way to promote a programming blog?

  - by paul

  (The guys from 'Programmers' referred me here...) How do you promote your programming blog? I recently started http://blackforestcoder.blogspot.com/ to record my progress working with new technologies and ideas. The main aim being to provide a list of pitfalls and solutions and also to get feedback from readers. Since I set it up 10 days ago I have only had about 2-3 hits even though Google is supposed to be indexing it. How might I boost the hit rate?

• Is there a difference between "self-plagiarizing" in programming vs doing so as a writer?

  - by makerofthings7

  I read this Gawker article about how a writer reused some of his older material for new assignments for different magazines. Is there any similar ethical (societal?) dilemma when doing the same thing in the realm of Programming? Does reusing a shared library you've accumulated over the years amount to self-plagarizm? What I'm getting at is that it seems that the creative world of software development isn't as stringent regarding self-plagarism as say journalism or blogging. In fact on one of my interviews at GS I was asked what kind of libraries I've developed over the years, implying that me getting the job would entail co-licensing helpful portions of code to that company. Are there any cases where although it's legal to self-plagarize, it would be frowned upon in the software world?

• How Can Someone With Minimum Programming Experience Publish an App of an Existing Program not found in the Software Centre?

  - by Brenton Horne

  There's a free mathematics software that I would like to see in Ubuntu Software Centre, called, 'Sage.' I have minimal experience in programming, so I'm basically here asking if someone could either tell me how to accomplish this without said instructions being completely over my head or if someone could do it for me. For further information here's the sage homepage: http://sagemath.org/ and the .tar.lzma file for its installation is ~500MB and it takes around 2.2 GB on the HDD when installed, I found at least on 32 bit i386 Ubuntu 12.04 LTS. Any help will be greatly appreciated!

• How can I get started programming OpenGL on Mac OS X?

  - by Michael Stum

  I'm trying to start OpenGL programming on a Mac, which brings me into unknown territory on a lot of things. During the day, I'm a Web Developer, working in C# and before that in PHP and Delphi, all on Windows. During the night, I try to pick up Mac/OpenGL skills, but everything is so different. I've been trying to look for some books, but the OpenGL books are usually for iOS (tons of them out there) and the Mac Books usually cover "normal" application Development. I want to start simple with Pong, Tetris and Wolfenstein. I see that there are a bunch of different OpenGL Versions out there. I know about OpenGL ES 1&2, but I don't know about the "big" OpenGL Versions - which ones are commonly supported on 10.6 and 10.7 on current (2010/2011) Macs? Are there any up to date (XCode 4) books or tutorials? I don't want to use a premade Engine like Unity yet - again, I know next to nothing about any Mac development.

• Lean/Kanban *Inside* Software (i.e. WIP-Limits, Reducing Queues and Pull as Programming Techniques)

  - by Christoph

  Thinking about Kanban, I realized that the queuing-theory behind the SW-development-methodology obviously also applies to concurrent software. Now I'm looking for whether this kind of thinking is explicitly applied in some area. A simple example: We usually want to limit the number of threads to avoid cache-thrashing (WIP-Limits). In the paper about the disruptor pattern[1], one statement that I found interesting was that producer/consumers are rarely balanced so when using queues, either consumers wait (queues are empty), or producers produce more than is consumed, resulting in either a full capacity-constrained queue or an unconstrained one blowing up and eating away memory. Both, in lean-speak, is waste, and increases lead-time. Does anybody have examples of WIP-Limits, reducing/eliminating queues, pull or single piece flow being applied in programming? http://disruptor.googlecode.com/files/Disruptor-1.0.pdf

• Is OO-programming really as important as hiring companies place it?

  - by ale

  I am just finishing my masters degree (in computing) and applying for jobs.. I've noticed many companies specifically ask for an understanding of object orientation. Popular interview questions are about inheritance, polymorphism, accessors etc. Is OO really that crucial? I even had an interview for a programming job in C and half the interview was OO. In the real world, developing real applications, is object orientation nearly always used? Are key features like polymorphism used A LOT? I think my question comes from one of my weaknesses.. although I know about OO.. I don't seem to be able to incorporate it a great deal into my programs. I would be really interested to get peoples' thoughts on this!

• Is Ruby on Rails' Active Record an example of Aspect-Oriented Programming?

  - by B Seven

  From Clean Code, about Cross-Cutting Concerns: Note that concerns like persistence tend to cut across the natural object boundaries of a domain. You want to persist all your objects using generally the same strategy, for example, using a particular DBMS... Is Active Record an example of aspect-oriented programming? In AOP, modular constructs called aspects specify which points in the system should have their behavior modified in some consistent way to support a particular concern. This specification is done using a succinct declarative or programmatic mechanism. If Active Record is an example of AOP, what is the "aspect"? Is it the class declaration that inherits from Active Record? class Foo < ActiveRecord::Base

• Are there similarities between operating system kernels and programming language kernels?

  - by rahmu

  I know very little about Smalltalk but I noticed that there's a frequent mention of the "kernel". Dan Ingalls prime maintainer of several implementations of Smalltalk also worked on a Javascript environment called "Lively Kernel" and in Peter Siebel's book he kept mentionning the "kernel". I cannot help but think that it is no coincidence that the creators of Smalltalk used the name of a (central) part of operating systems to refer to a particular component of their language. Was it because Smalltalk intended to act as an operating system? Was it because theory behind programming languages and operating systems have a lot in common? What is the reason behind the common appelation of the two components?

• Which specific programming activities do women, on average, perform better than men? [closed]

  - by blueberryfields

  Following a recent discussion with female associates in hiring positions for software development/engineering positions, I found out that this kind of information would be incredibly useful to helping make sure that the workforce shows a gender balance. So I went looking. I've found various literature speaking about risk-taking behaviour and patterns, and other statistical differences between men and women when it comes to work performance. See for example this article related to hedge fund management. I have yet to see any such comparison in the computing field. To restate the question: Which specific programming activities do women, on average, perform better than men? Please back up your answers with specific details, preferably by linking to relevant research or, failing that, explaining what you're basing the information on.

• Why are cryptic short identifiers still so common in low-level programming?

  - by romkyns

  There used to be very good reasons for keeping instruction / register names short. Those reasons no longer apply, but short cryptic names are still very common in low-level programming. Why is this? Is it just because old habits are hard to break, or are there better reasons? For example: Atmel ATMEGA32U2 (2010?): TIFR1 (instead of TimerCounter1InterruptFlag), ICR1H (instead of InputCapture1High), DDRB (instead of DataDirectionPortB), etc. .NET CLR instruction set (2002): bge.s (instead of branch-if-greater.signed), etc. Aren't the longer, non-cryptic names easier to work with?

• Best options for freelance or part-time programming? [closed]

  - by Andrew

  I apologize in advance if this is an inappropriate question for this SE. A few years back I was all set to study computer science and get a job programming, but went a totally different route and went into healthcare. I currently work as a paramedic on a rotating 24/48 schedule, so I have two days off for every day I work, and a decent bit of downtime on the days that I do work. I've been looking at ways to earn some extra money with all that spare time, and was wondering if it'd be worth the effort to try and find a part-time/freelance gig. I know HTML/CSS, PHP, and I'm pretty familiar with Python and Ruby (and Rails). Anyways, was hoping that someone could point me in the right direction as what "skill set" would give me the best chance to be able to land a part-time/freelance gig. I realize this is a rather open-ended question but any direction is appreciated.

• What are startups expecting when they ask you to solve a programming challenge before interviewing? [closed]

  - by Swapnil Tailor

  I have applied to couple of startups and most of them are asking to solve programming challenge before they start on the interviewing candidate. I have submitted couple of the solutions and all the time getting rejected in the initial screening. Now what I think is, they will see my coding style, algorithm and OOD concepts that I have used to solve the problem. Can you guys input more on it as what other details are taken into consideration and how can I improve my coding for getting selected. By the way, I did all my coding in either Java/Perl. EDIT I feel the biggest reason for rejection is code didn't work for couple of use cases.

• When to learn the command line version of a programming tool ?

  - by explorest

  Almost every programming tool has a command line version; many of which also have a gui version. It takes a lot of time and memorization effort to learn the different commands and various options/switches om the command line version. So I have a couple of questions (which are not necessarily mutually exclusive): 1) When would you bother learning/memorizing the commands in the command line version of a tool which also comes in a gui version ? 2) What tools should I learn the command line version of ? .... compilers ? version control system ? etc, etc

• Anti-depressant and programming: does it reduce your thinking and focusing abilities ?

  - by user12358

  I wanted to ask your opinion on anti-depressants, since I took them daily for 3 years now, but I can't be sure if I'm less perfomant with them or without, since I never withdrawed. I'm still at school at the age of 25, still having some motivation problems (for example I can't get used to do something at school if I don't think it will teach me something), but I'm quite motivated to work in the video-game field, since I have some personnal projects in mind. I know C++ programming etc, I'm still learning techniques, but do you think I should try more to do my project instead of just following the work I'm assigned to ? Have you had experience with depression or anti-depressants ? How did it affect your work ? Do you think that being depressed or half-depressed can improve creativity ? Do you feel it has affected the way you end up writing your algorithms ? EDITED

• is it possible to get a programming job in the bay area?

  - by user475119

  Is it my perception or is it reality that it is harder to get software development work in Silicon Valley, than in other population centers? My theory is that some of the best and brightest (and youngest) are all here. All working for the top tech companies. And, little ol' me, over 40, math degree (not at Standford or Berkeley), ok at algorithms, and with many skills with many programming tools and concepts, but not published, and not top my class has a bit of a tough time competing. (I'm a Python programmer, by the way.) Thanks
