  • How to make pulseaudio and ubuntu detect the same audio device as alsa driver

    - by Kiwy
    I use Ubuntu 14.04 x64 and I use gnome-shell on my laptop. I have a Bose companion 5 (which is basically a USB sound system) and a HDMI port, both does work perfectly when I just boot with the cable plugin. However, when my laptop go to sleep or get unplugged from those two outputs, if I plug back the device, I end up without any hardware detection (only the built-in speakers) from pulse and gnome-shell sound output selector while if I use alsamixer, the device look up and ready. gstreamer-properties allow me to select and test effectively any device but while alsa recognize any device on the run, pulse is not capable of handling things correctly, my question is then: How can I make pulse detect and use the same hardware as alsa, or how to remove completely and gracefully pulseaudio (meaning volume applet running in gnome shell) I don't mind if the project implies to recompile half gnome shell if it implies those audio outputs work all the time. Pulse does not list my soundcard when I use command pactl list cards while the module plug&play for sound card is loaded in pactl list modules. I really don't know what to do, the behavior seems pretty random.

  • How to go from Mainframe to the Cloud?

    - by Ruma Sanyal
    Running applications on IBM mainframes is expensive, complex, and hinders IT responsiveness. The high costs from frequent forced upgrades, long integration cycles, and complex operations infrastructures can only be alleviated by migrating away from a mainframe environment.  Further, data centers are planning for cloud enablement pinned on principles of operating at significantly lower cost, very low upfront investment, operating on commodity hardware and open, standards based systems, and decoupling of hardware, infrastructure software, and business applications. These operating principles are in direct contrast with the principles of operating businesses on mainframes. By utilizing technologies such as Oracle Tuxedo, Oracle Coherence, and Oracle GoldenGate, businesses are able to quickly and safely migrate away from their IBM mainframe environments. Further, running Oracle Tuxedo and Oracle Coherence on Oracle Exalogic, the first and only integrated cloud machine on the market, Oracle customers can not only run their applications on standards-based open systems, significantly cutting their time to market and costs, they can start their journey of cloud enabling their mainframe applications. Oracle Tuxedo re-hosting tools and techniques can provide automated migration coverage for more than 95% of mainframe application assets, at a fraction of the cost Oracle GoldenGate can migrate data from mainframe systems to open systems, eliminating risks associated with the data migration Oracle Coherence hosts transactional data in memory providing mainframe-like data performance and linear scalability Running Oracle software on top of Oracle Exalogic empowers customers to start their journey of cloud enabling their mainframe applications Join us in a series of events across the globe where you you'll learn how you can build your enterprise cloud and add tremendous value to your business. In addition, meet with Oracle experts and your peers to discuss best practices and see how successful organizations are lowering total cost of ownership and achieving rapid returns by moving to the cloud. Register for the Oracle Fusion Middleware Forum event in a city new you!

  • cpufreq-selector, cpufreq-info reporting wrong max speed

    - by dty
    Hi, I've just built a new machine with a Core i5-760 CPU. Max speed is 2.80GHz (turbo mode notwithstanding). I've also done a vanilla install of Ubuntu 10.10. I've added the cpufreq-selector applet to the top panel, and its menus only allow me to select up to 2.39GHz. If I select the "performance" governor, it also shows 2.39GHz. cpufreq-info reports: $ cpufreq-info cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email protected], please. analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 2 3 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 1.20 GHz - 2.39 GHz available frequency steps: 2.39 GHz, 2.26 GHz, 2.13 GHz, 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz, 1.46 GHz, 1.33 GHz, 1.20 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 1.20 GHz and 2.39 GHz.

And ideally to report the actual speed when running in turbo mode too, but that's not critical. Edit: I should probably add that the BIOS (& Windows) are quite happy that it's a 2.80GHz CPU. Thanks.

  • Why can't I create direct3d objects?

    - by quakkels
    I've been programming professionally for years using languages like VBScript, JavaScript, and C#. As a hobby, I'm getting into some c/c++ and games programming with DirectX. I am running into an issue where I cannot create direct3d objects. I am using Visual C++ 2010 Express. After I installed vc++2010express I then installed the June 2010 release of DirectX. I am trying to include DirectX via #pragma statements. This is the code I have so far in my winmain.cpp source file: #include <Windows.h> #include <d3d11.h> #include <time.h> #include <iostream> using namespace std; #pragma comment(lib, "d3d11.lib") #pragma comment(lib, "d3dx11.lib") // program settings const string AppTitle = "Direct3D in a Window"; const int ScreenWidth = 1024; const int ScreenHeight = 768; // direct3d objects LPDIRECT3D11 d3d = NULL; // this line is showing an error The type LPDIRECT3D11 is showing an error: Error: Identifier "LPDIRECT3D11" is undefined Am I missing something here to get VC++2010Express to recognize and load the DirectX libs? Thanks for any help.

  • Internal Mic not working on Dell Adamo 13

    - by AFD
    So I'm using Elementary Luna Beta (based on Ubuntu 12.04 LTS) on a spare HDD after successfully using Jupiter release (based on 10.10) for many years. In Jupiter I had my internal mic work out of the box and with Skype installed from deb it was all setup without having to step foot inside the terminal. In Luna Beta the internal mic is not recognised by the OS and so also not recognised by Skype. I believe the hardware is this (from sudo lshw): *-multimedia description: Audio device product: 82801I (ICH9 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 03 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=HDA Intel latency=0 resources: irq:46 memory:f8600000-f8603fff As well as this I ran cat /proc/asound/card0/codec* | grep Codec which gave me: Codec: IDT 92HD73C1X5 Codec: Intel Cantiga HDMI How do I tweak Luna to get this hardware working properly? I'm able to switch out my Luna HDD with the Jupiter HDD to help troubleshoot what the differences are between the two and why the more recent OS can't find / use the mic correctly. Thanks in advance for any help you can give.

  • How to start a high school Java/Android development club for 13-17 year olds

    - by PaulHurleyuk
    My wife is a high school maths teacher, and is considering starting a programming club for 13-17 years olds who show an interest. Their interest seems to be around Apps and Android which I have little experience of. The kids would be (presumably) interested in programming, and have a fairly high level of computing knowledge. We would provide them with resources and some knowledge, but hopefully a lot would be self guided. I'm hoping stack overflow'ers can provide some tips or starting points. Specific things I think I'll need are; A development Environment; Currently I'm looking towards Java and Android, developed in Eclipse, probably installed on donated older hardware Some initial direction; There seem to be a plethora or 'start android' tutorials, so some recommendations for good ones are valuable, as are recommended paper books A Target; Some final project they should be shooting for A Route; This is where I'm most stuck, how to lead them through the required Java concepts and learning they would need Some related questions already out there Language+IDE for teaching high school students? Teaching "web design/development" to high-school home-school group. Good sources? How can I bootstrap a software development community at my school?

  • Tried teaching myself to program before college, accidently overwhelmed myself, tips?

    - by Gunnar Keith
    I'm sixteen, I'm overly interested in programming, and I'm currently taking IT classes during my mornings in high school. Last year, I tried teaching myself to code. It was quite exciting, but all I did was watch TheNewBoston's videos on YouTube for Python. After his tutorials, I just did research, made some CMD programs, and that's it. After that, I got cocky and got my feet wet in many other languages. Java, C++, C#, Perl, Ruby... and it overwhelmed me. Which made it less fun to code. I want to go to college for a 2 year programming course. And I want to make writing code my profession. But how do you recommend I attack re-learning it all again? Start with Python? Don't even try? Also, I'm not 100% in math, but I'm good friends with a lot of programmers, who say they suck at math, but manage to code just fine. I'm not looking for negative feedback. I just want the proper head-start on things before college.

  • Migration of PowerBuilder application to multiplatform

    - by Alex Bibiano
    I developed a client/server application with PowerBuilder in the past for medical clinics and done maintenance for it until now. Now, some clients are asking me to develop a release for Mac/Linux and need some advice about what programming language/technology is best suited for it and the learning curve. It’s not a very very big program but I’m the only developer and have done it in my spare time. PowerBuilder is very productive for this kind of projects (database centric), but it’s not multiplatform and it’s hard to sell PowerBuilder application now days (web, .NET, java sells a lot better with his marketing). My programming skills: - I studied C and C++ in the past (university) but never used it on real projects - Have some Java experience but not in desktop applications - Some experience with Ruby on Rails for web projects - Good skills with PowerBuilder and C# (.NET) (there are my main developing languages) My first dilemma is if I change the desktop application to a web interface, but I think the user will lose some user-experience, and some doctors don’t have a clinic (they are alone at home with my software). I think installing a web application (with webserver) for one user will be overwhelming. If I continue developing desktop application, what is at the moment a good framework/toolset to learn having my skills? Somebody has had similar experiences? A lot of thanks

  • Why is C++ often the first language taught in college?

    - by Casey Patton
    My school starts the computer science curriculum with C++ programming courses, meaning this is the first language that many of the students learn. I've seen that many people dislike C++, and I've read a variety of reasons why. It almost seems to be popular opinion that C++ isn't a very good language. I get the impression it's not very liked based on some questions on StackExchange as well as posts such as: http://damienkatz.net/2004/08/why-c-sucks.html http://blogs.kde.org/node/2298 http://blogs.cio.com/esther_schindler/linus_torvalds_why_c_sucks http://www.dacris.com/blog/2010/02/16/why-c-sucks-part-2/ etc. (Note: It is not my opinion that C++ is a bad language. In fact, it's the main language I use. However, the internet as well as some professors have given me the impression that it's not a very widely liked language. In fact, one of my professor constantly rags on C++, yet it's still the starting language at my college!) With that in mind, why is this the first language taught at many schools? What are the reasons for starting a programming curriculum with C++? Note: This question is similar to "Is C++ suitable as a first language", but is a little different since I'm not interested in whether it's suitable, but why it's been chosen.

  • Which reference provides your definition of "elegant" or "beautiful" code?

    - by Donnied
    This question is phrased in a very specific way - it asks for references. There was a similar question posted which was closed because it was considered a duplicate to a good code question. The Programmers FAQ points out that answers should have references - or its just an unproductive sharing of (seemingly) baseless opinions. There is a difference between shortest code and most elegant code. This becomes clear in several seminal texts: Dijkstra, E. W. (1972). The humble programmer. Communications of the ACM, 15(10), 859–866. Kernighan, B. W., & Plauger, P. J. (1974). Programming style: Examples and counterexamples. ACM Comput. Surv., 6(4), 303–319. Knuth, D. E. (1984). Literate programming. The Computer Journal, 27(2), 97–111. doi:10.1093/comjnl/27.2.97 They all note the importance of clarity over brevity. Kernighan & Plauger (1974) provide descriptions of "good" code, but "good code" is certainly not synonymous with "elegant". Knuth (1984) describes the impo rtance of exposition and "excellence of style" to elegant programs. He cites Hoare - who describes that code should be self documenting. Dijkstra (1972) indicates that beautiful programs optimize efficiency but are not opaque. This sort of conversation is qulaitatively different than a random sharing of opinions. Therefore, the question - Which reference provides your definition of "elegant" or "beautiful" code? "Which *reference*" is not subjective - anything else will most likely shut the thread down, so please supply *references* not opinions.

  • C++ Numerical Recipes &ndash; A New Adventure!

    - by JoshReuben
    I am about to embark on a great journey – over the next 6 weeks I plan to read through C++ Numerical Recipes 3rd edition http://amzn.to/YtdpkS I'll be reading this with an eye to C++ AMP, thinking about implementing the suitable subset (non-recursive, additive, commutative) to run on the GPU. APIs supporting HPC, GPGPU or MapReduce are all useful – providing you have the ability to choose the correct algorithm to leverage on them. I really think this is the most fascinating area of programming – a lot more exciting than LOB CRUD !!! When you think about it , everything is a function – we categorize & we extrapolate. As abstractions get higher & less leaky, sooner or later information systems programming will become a non-programmer task – you will be using WYSIWYG designers to build: GUIs MVVM service mapping & virtualization workflows ORM Entity relations In the data source SharePoint / LightSwitch are not there yet, but every iteration gets closer. For information workers, managed code is a race to the bottom. As MS futures are a bit shaky right now, the provider agnostic nature & higher barriers of entry of both C++ & Numerical Analysis seem like a rational choice to me. Its also fascinating – stepping outside the box. This is not the first time I've delved into numerical analysis. 6 months ago I read Numerical methods with Applications, which can be found for free online: http://nm.mathforcollege.com/ 2 years ago I learned the .NET Extreme Optimization library www.extremeoptimization.com – not bad 2.5 years ago I read Schaums Numerical Analysis book http://amzn.to/V5yuLI - not an easy read, as topics jump back & forth across chapters: 3 years ago I read Practical Numerical Methods with C# http://amzn.to/V5yCL9 (which is a toy learning language for this kind of stuff) I also read through AI a Modern Approach 3rd edition END to END http://amzn.to/V5yQSp - this took me a few years but was the most rewarding experience. I'll post progress updates – see you on the other side !

  • Boot failure randomly. Can someone help?

    - by desgua
    I often get stuck at the boot on battery. I can suspend and hibernate without any trouble (even on battery). If I plug the energy cable everything goes right most of the time (edited June 13). Adding "acpi=off" doesn't solve the issue. Disabling power save from LAN at BIOS doesn't solve this too. Memory test seems to be ok: I can even compile a kernel without a problem: Has someone a tip for this? (I have the same questions marks in my mind as the image shows if not more :-/ ) obs.: this is an upgraded installation from Natty alpha. edited I (May 22): I've installed a brand new final 11.04 and got the bug again. edited II (June 13): I thought it was solved but it is not. After spending eight days off, the same problem happened even with the power cable connected. I had to reboot about 6 times until success. edited III (June 14): I can boot (even with battery) if I disconnect the cable and take off the battery for a few seconds. This lead me to conclude that maybe something is kept into memory of some hardware. Maybe or maybe not related but I also have touchpad issues (jumps) with this machine. edited IV (June 25): I opened gconf-editor and went to apps gnome-power-manager and disabled everything possibly related to suspend or hibernate. No help. Also I grabbed a Fedora live usb pendrive and got the same problem: So I think it is a hardware problem related issue.

  • Scene graphs and spatial partitioning structures: What do you really need?

    - by tapirath
    I've been fiddling with 2D games for awhile and I'm trying to go into 3D game development. I thought I should get my basics right first. From what I read scene graphs hold your game objects/entities and their relation to each other like 'a tire' would be the child of 'a vehicle'. It's mainly used for frustum/occlusion culling and minimizing the collision checks between the objects. Spatial partitioning structures on the other hand are used to divide a big game object (like the map) to smaller parts so that you can gain performance by only drawing the relevant polygons and again minimizing the collision checks to those polygons only. Also a spatial partitioning data structure can be used as a node in a scene graph. But... I've been reading about both subjects and I've seen a lot of "scene graphs are useless" and "BSP performance gain is irrelevant with modern hardware" kind of articles. Also some of the game engines I've checked like gameplay3d and jmonkeyengine are only using a scene graph (That also may be because they don't want to limit the developers). Whereas games like Quake and Half-Life only use spatial partitioning. I'm aware that the usage of these structures very much depend on the type of the game you're developing so for the sake of clarity let's assume the game is a FPS like Counter-Strike with some better outdoor environment capabilities (like a terrain). The obvious question is which one is needed and why (considering the modern hardware capabilities). Thank you.

  • Which language meets my needs? [closed]

    - by Gerald Goward
    I am a junior C# developer, working for half a year now. In my company I am working on some enterprise projects and after doing it for quite some time I understood that I dont like enterprise projects. I have my own browser-game written in PHP+MySql with some simple HTML+CSS and I have 300 active (those, who entered the game at least once per 5 days) players currently :) After thinking quite some time I understood that I am interested in: 1). Web-development AND 2). standalone programs (but not enterprise ones). 3). Development for mobile platforms is also nice, Android/iOs. 1st and 2nd categories are what I want the most. Android/iOs is good too. I am NOT interested in big systems which are hard to integrate, I am not interested in enterprise systems. In future I would like to start my own business/projects. I would like to create my own projects or/and create a small programmers company to create and release own products. Please tell me what programming language(s)/technologies would you advice me for it? Thanks alot! UPD: It's NOT a "which language is better" or any flame/holywar generating topic since I ask for language that suits my EXACT needs better. I believe C++ is better for low-level coding, while PHP is good for web-development and Object-C being made for iOs. I am still newbie at programming so dont hate me please.

  • Modelling work-flow plus interaction with a database - quick and accessible options

    - by cjmUK
    I'm wanting to model a (proposed) manufacturing line, with specific emphasis on interaction with a traceability database. That is, various process engineers have already mapped the manufacturing process - I'm only interested in the various stations along the line that have to talk to the DB. The intended audience is a mixture of project managers, engineers and IT people - the purpose is to identify: points at which the line interacts with the DB (perhaps going so far as indicating the Store Procs called at each point, perhaps even which parameters are passed.) the communication source (PC/Handheld device/PLC) the communication medium (wireless/fibre/copper) control flow (if leak test fails, unit is diverted to repair station) Basically, the model will be used as a focus different groups on outstanding tasks; for example, I'm interested in the DB and any front-end app needed, process engineers need to be thinking about the workflow and liaising with the PLC suppliers, the other IT guys need to make sure we have the hardware and comms in place. Obviously I could just improvise in Visio, but I was wondering if there was a particular modelling technique that might particularly suit my needs or my audience. I'm thinking of a visual model with supporting documentation (as little as possible, as much as is necessary). Clearly, I don't want something that will take me ages to (effectively) learn, nor one that will alienate non-technical members of the project team. So far I've had brief looks at BPMN, EPC Diagrams, standard Flow Diagrams... and I've forgotten most of what I used to know about UML... And I'm not against picking and mixing... as long as it is quick, clear and effective. Conclusion: In the end, I opted for a quasi-workflow/dataflow diagram. I mapped out the parts of the manufacturing process that interact with the traceability DB, and indicated in a significantly-simplified form, the data flows and DB activity. Alongside which, I have a supporting document which outlines each process, the data being transacted for each process (a 'data dictionary' of sorts) and details of hardware and connectivity required. I can't decide whether is a product of genius or a crime against established software development practices, but I do think that is will hit the mark for this particular audience.

  • Heading Out to Oracle Open World

    - by rickramsey
    In case you haven't figured it out by now, Oracle reserves an awful lot of announcements for Oracle Open World. As a result, the show is always a lot of fun for geeks. What will the Oracle Solaris team have to say? Will the Oracle Linux team have any surprises? And what about Oracle hardware? For my part, I'll be one of the lizards at the OTN Lounge with the OTN crew, handing out t-shirts to system admins and developers, or anyone who is willing to impersonate one. I understand, not everyone can have the raw animal magnetism of a sysadmin, or the debonair sophistication of a C++ developer, so some of you have no choice but to pretend. I won't judge. I'll also be doing video interviews of as many techie people as I can corner. I've got more than 30 interviews already scheduled. Most of them will be 3-5 minutes long. I'll be asking our best technical minds what's cool about their latest technologies and what impact it will have on system admins or system developers. I'll be posting those videos here: Find OTN Systems Videos from Oracle Open World Here! We've got some great topics in mind. A dummies guide to hardware-assisted cryptography with Glenn Brunette. ZFS deduplication. The momentum building around Oracle Solaris 11, with Lynn Rohrer, plus conversations with partners who have deployed Oracle Solaris 11. Migrating to Oracle Database with SQL Developer. The whole database cloud thing. Oracle VM and, of course, Oracle Linux. So even if you can't be part of the fun, keep an eye out for the videos on our YouTube channel. - Rick Website Newsletter Facebook Twitter

  • I know how to program, and how to learn how to program, but how/where do you learn how to make systems properly?

    - by Ryan
    There are many things that need to be considered when making a system, let's take for example a web based system where users log in and interact with each other, creating and editing content. Now I have to think about security, validation (I don't even think I am 100% sure what that entails), "making sure users don't step on each others feet" (term for this?), preventing errors in many cases, making sure database data doesn't become problematic through unexpected... situations? All these things I don't know how or where to learn, is there a book on this kind of stuff? Like I said there seems to be a huge difference between writing code and actually writing the right code, know what I mean? I feel like my current programming work lacks much of what I have described and I can see the problems it causes later, and then the problems are much harder to solve because data exists and people are using it. So can anyone point me to books or resources or the proper subset of programming(?) for this type of learning? PS: feel free to correct my tags, I don't know what I am talking about. Edit: I assume some of the examples I wrote apply to other types of systems too, I just don't know any other good examples because I've been mostly involved in web work.

  • Finding a mentor online [closed]

    - by Athena Santos
    Possible Duplicate: How to find programming mentor? I'm a programming intern, but I want to "transition" into a product manager role after graduation. I just know that I will never be a super A++ Rockstar programmer, but from my internship I know that I can be a great program manager..one of those presumably rare people who can code well (enough)/speak programmer-ese and management-ese. Being a girl, I am looking for both male and female mentors. Female, because they know what its like to be a minority, and male, because..well, you guys are tough, and I believe to succeed in tech, a girl's gotta know how to act like a man (when appropriate). I've found some really amazing people I'd like to ask to be my mentor (in blogs, magazines, etc), but sadly, I live far, far away from them. Will be awkward/rude if I shoot them an email about being a mentor? What is the best way to establish a relationship with people like these that I admire? Any volunteers? :) Thank you in advance, and I hope you all have a great day/night.

  • How do I get my graphic card to work properly?

    - by Lucas
    I been having some problems with my graphic card for a time now. But I had enough when I did'nt get Oil Rush to work on my HP Pavilion g6. The system has suggested hardware drivers for me, but the first time I installed them they pretty much fucked up the graphics. After some time I managed to get the computere to work properly (I thought) again. When the game did'nt work I tried to the hardware drivers for the graphic card anyway. First of all there was to possible choices insted of one, as the last time I installed the drivers (when it did'nt work out so good). The choices are: ATI/AMDs proprietary video drivers FGLRX (update for edition) and Proprietary FGLRX-video drivers for ATI/AMD I realized the drivers probebly are pretty much the same, so I tried the first one. But this did'nt work. Instead I was asked to "Look in to /usr/var/log/jockey.log". This did'nt helped me much. Instead I choiced the other one, wich was installed and after reboot there where some changes. First of all there was a lot more details for Unity that was'nt there before and some shortkeys are now working that did'nt before (like Ctrl + T and the Prt Sc-button). But overall everything doesn't work as it used to. Like when you browse between the workspaces it doesn't look the same. To get to the point: it doesn't work well right now even if I got some things better and now will not Oil Rush (as I mentioned in the beginning) even start. SO! Can someone give me any advice with this? I'm stuck. Can't manage to see whats wrong right now. Any help? My graphic card is AMD Radeon HD 6470M.

  • How do client-server cooperation based games like Diablo 3 work?

    - by edgar
    Diablo 3 cooperates with Blizzard servers even during single player games. In fact, Blizzard has had problems with the games "melting their servers." I would like to ask: How do the client and the server communicate? What details does the client leave to the server, and vice versa? What details are redundant - both the client and the server know - and how often do they disagree? The previous paragraph contains the important questions, but I have a few more that I must explain my motivation towards. I am interested in the programming of botting. Ethical botting - I don't plan on actually abusing the automation to run 24/7. I just find it to be a great programming challenge to glean information from a game, and then make decisions from that information. I am stuck in the starting gate. The unofficial questions from this post would be: How can I make a bot (language, tools, libraries)? Can I get information through the communication between client and server, rather than the brute force pixel detection easily used in more static games? There probably is a trust issue, and to that all I can say is that I promise not to abuse the answers. But please feel free to answer any of the questions you feel comfortable with. Thank you!

  • Will people respect a Masters of Science in IT w/software engineering concentration from RPI?

    - by twneale
    Here's my thing: I got my undergraduate degree in political science, then a law degree. Then I figured out that I love programming and I'm pretty good at it too. It's fun and rewarding enough for me that I'd prefer to do it for a living over almost any form of pure law practice. So I'm looking at getting a masters degree to put some weight behind a possible career switch. If I actually want to develop software (web, in particular), would people in programming circles respect a master's of science in IT? Specifically, consider as an example the MS in IT from Rensselaer Polytechnic Institute (with a concentration in software engineering). Here's the home page: http://www.rpi.edu/IT/graduate/masters_program.html In particular, I mean to draw a contrast between IT as specifically contemplated by the RPI masters program (an interdisciplinary tech/business program) and other MS degrees in computer science or software engineering that focus more on the science and technical aspects. I guess I want to make sure that other programmers would respect my credentials and not consider me as different or underqualified based on the connotations of the phrase "IT". I believe RPI has an unimpeachable reputation for hard science, and the program seems excellent, but it still matters to me how people in industry would perceive it.

  • I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

    - by Shin San
    I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?

  • What are some Java patterns well-suited for fast, algorithmic coding?

    - by Casey Chu
    I'm in college, and I've recently started competing in programming competitions with my friends. These competitions involve solving algorithmic problems quickly. It's a lot of fun, but there's one problem: I'm forced to use Java. (My teammates use Java.) Background: I'm a self-taught JavaScript programmer, and it hurts to write Java code. I find it very verbose and inflexible, and I feel slowed down when having to declare types and decide which of the eighty list data structure to use. I'm also frustrated about the lack of functional programming features and how verbose using regular expressions, arrays, and dictionaries are. As an example, consider the problem of finding the length of the longest string of consecutive characters in a given string. So the string XX22BBBBccXX222 would give 4, for the string of four Bs. In Java, I'd have to loop through and manually count characters and manually keep track of the maximum. (That's at least as far as I'm aware -- I'm not as familiar with Java as I am with JavaScript.) In JavaScript, I'd find it like this: var max = Math.max.apply(Math, str.match(/(.)\1*/g).map(function (s) { return s.length; })); Much quicker and simpler, in my book. The question: what are some Java features, techniques, or patterns well-suited for fast, algorithmic coding?
