• Looking for job advice [closed]

  - by EntryLevelJavaDeveloper

  I am a software developer for a government agency in DC, and I have recently completed one year of employment. I am generally dissatisfied with my experiences here. I do not want to gripe too much, but I do not spend a lot of time doing actual development on projects. I am asked to do everything under the sun: write requirements, review specs, test, attend random meetings, but actual coding makes up a small fraction of my time. The coding itself is fairly straightforward and simple so it feels like I am not growing from my experiences. I am not tasked with more challenging work, and I find the experiences are not rewarding. If I had a stronger resume/more work experience, I'd leave the position immediately but combined with the present economy, I am hesitant to leave. I have several questions: Does anybody have experiences like this? How did you make the most of it? I am currently doing some side projects, making simple webpages for people, but aside from that, and open source projects, what other things are out there? What are general benchmarks for a developer after one year of professional experience? What should I be expected to know/do? I am outsider (coming from a math/science background) so I do not know what exactly I should know/do. Is it possible to obtain a mentorship with a mid/senior developer to learn? If so, how can I go about making contacts in the DC area?

• what to learn & practice to be a programmer (not for Job) [closed]

  - by Hanan N.

  I want to be able to write programs (tools) for my own needs, and I want to tell the computer what to do, not to be strict to what other's told it to do. I have a good knowledge of Linux & Windows, I am also have a bit of Python in my head, but I think that I need some guidance on what languages or practices to invest my time into in order to be able to tell the computer what to do. I know there is a lot of posts similar to what I am asking here, but there is a big difference and so I have opened this thread. My goal isn't to work at a company, so I don't need to learn how to work as a team, I don't need to learn as much how to maintain my code nor how to write it nice for others to understand (I know it is important but not for me). I don't want to learn it as a profession, but as a serious hobby (you can call it hacking as long as you know what cracking means), my end goal is to be able to understand other's people code, and to write my own code with a lot of deep knowledge of the ins and outs of the computer system in order to gain from it as much as I can. So in essence my questions are: How can I understand, in depth, computers, in order to exploit them as much as I can? What should I learn? Are there any books that I should read? Is it possible to do this, or do I have to learn every aspect of programming?

• How to access Ubuntu Server from local PC?

  - by Roland

  Today I installed my first web server, which is Ubuntu 12.04 LTS. I got Apache, PHP and MySql working, there is even MyPHPAdmin! Everything is working fine on that PC, but the problem is that I have no idea how to connect to this server from my PC. Just to clarify- I got one PC that I work on and got another one, which has Ubuntu Server running. I even managed to connect them through the router, which I made to work as a switch. I can see the Ubuntu Server on my Windows PC in "Network", but it's empty, I can't see any files. I tried to share a folder etc/www on Server, but it shows an error saying something about right, that I'm not this folder's owner. I guess I'm not doing the right thing at all, am I? Even if I could see shared folder on my Windows PC- I would still be not able to type "somedomain.com" on Windows PC and access for example index.php or MySql database. So, the question is- how do I configure Ubuntu Server to be accessible from Windows PC?

• Been doing .NET for several years and am thinking about a platform change. Where do people suggest I go?

  - by rsteckly

  Hi, I've been programming in .NET for several years now and am thinking maybe its time to do a platform switch. Any suggestions about which platform would be the best to learn? I've been thinking about going back to C++ development or just focusing on T-SQL within the Microsoft stack. I'm thinking of switching because: a) I feel that the .NET platform is increasingly becoming commodified--meaning that its more about learning a GUI and certain things to click around than really understanding programming. I'm concerned that this will lend itself to making developers on that stack increasingly paid less. b) It's very frustrating to spend your entire day essentially debugging something that should work but doesn't. Usually, Microsoft releases something that suggests anyone can just click here and there and poof there's your application. Most of the time it doesn't work and winds up sucking so much more time than it was supposed to save. c) I recently led a team in a small startup to build a WPF application. We were really hit hard with people complaining about having to download the runtime. Our code was also not portable to any other platform. Added to which, the ram usage and slowness to load of the app was remarkable for its size. I researched it and we could not find a way to optimize it. d) I'm a little concerned about being wedded to the Windows platform. What are the pros and cons of adding another platform and which platform do people suggest? Thanks!

• Ubuntu 12.10 hotkeys not working properly [closed]

  - by Sly

  A couple of weeks ago, I ran a distribution upgrade from 12.04 to 12.10. Unfortunately, something has seemed to happen with the hotkeys on the system. At first, I thought that maybe this was just a glitch with the global hotkeys. That didn't turn out to be the case, as the custom hotkey I added into the Ubuntu settings works for my editor. The only default hotkey that seems to have a problem launching is CTRL+ALT+T (Terminal). This wasn't such a big issue to begin with, because I can always just drag the Terminal to my launcher and launch it from there. However, I was on Chrome earlier and tried to do SHIFT+CTRL+DEL to clear the history and it failed. I then tried to do SHIFT+ESC, just to see if the hotkey for the task manager would work.. and it did. I also thought it could be something with the "CTRL" key, since SHIFT+ESC works, but SHIFT+CTRL+DEL doesn't. That didn't turn out to be the case either, as keys like CTRL+ALT+DEL (logout) work perfectly fine. Not quite sure how to go about this, and I haven't found any errors in any of /var/log that raises any suspicion.

• How does Game Salad compare with Cocos2D in terms of 2D game development?

  - by jih

  I want to make some 2d games for iOS. I first come across cocos2d and kobold but then wanted something more graphical for rapid prototyping. I then found Game Maker which doesn't support iOS but is fairly easy to learn and then found Game Salad which supports iOS as well as other platforms. I know this question has been ask before but I want to know in terms of the types of games I want to develop what an learning investment path would be best. The types of games genre I am interest are: Side scrollers Simple games like diamond dash or ninja fruits, shanghai, etc Old fashioned zelda or dragonquest type (nintendo fan here:-) 2d adventure RPG games (real time or turn based) Mystery turn based games like carmen sandiego, wizardry, myst etc. So now the question becomes for me becomes which game development environment should I invest my time in learning. Game Salad or cocos2d? To make that decision I was wondering if experienced game programmers and help with some pointers: It would seem game salad would be great for quickies being graphical but in terms of 2d platform games etc would there be speed/performance/feature penalties? Are there certain 2d games genre of the 4 above that Game salad is better at while certain type cocos2d would be better at?

• Java or Python? Career/Start-up advice needed [closed]

  - by vim

  I have a full-time PHP job and I've been working with PHP for 5 years. As you can guess after spending 5 years I'm not willing to stay within this technology stack any more. I also worked with Java for 2 year before, so for me it looks more obvious to switch back to Java. However during last 5 years I was thinking about starting my own project, and now I think I have a very good SAAS idea. I'm completely confused what technology should I use for my project. I don't want to do it in PHP, and after reading many articles about rapid prototype development it seems to me that Django/Ruby is the best option. I will continue to work full time for my current employer because I need to pay my bills and will work on my project in my free time. The concern I have is should I do my project in Java or Python? To be realistic there is always a risk when you are doing your own project/start-up. If I do it in Java in the worst case scenario I believe I will be able to find a full time Java position because I already have some experience in Java + recent experience in my project. With regards to Python it looks like it is not very popular in my area and salaries are much more lower then for Java. On the other hand I have a feeling that if I chose Java it will take me a way longer to finish my project. Guys I'm completely confused and I need your advice. P.S. I have moved to London 2 years ago from another country, local guys are very welcome to share their thoughts about London's job market.

• ATI 9550 shows up as laptop in displays after update to 12.04, how do I fix this?

  - by D_H

  My guess is this is on here somewhere but I have searched and even tried looking at bunch of other similar video problems. My ATI 9550 shows up as laptop in displays after update to Ubuntu 12.04, how do I fix this? I found the following command on another post sudo lshw -c video. I get this when I run that command: *-display:0 UNCLAIMED description: VGA compatible controller product: RV350 AS [Radeon 9550] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 66MHz capabilities: agp agp-3.0 pm vga_controller bus_master cap_list configuration: latency=32 mingnt=8 resources: memory:c0000000-cfffffff ioport:c000(size=256) memory:e5000000-e500ffff memory:e4000000-e401ffff *-display:1 UNCLAIMED description: Display controller product: RV350 AS [Radeon 9550] (Secondary) vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0.1 bus info: pci@0000:01:00.1 version: 00 width: 32 bits clock: 66MHz capabilities: pm cap_list configuration: latency=32 mingnt=8 resources: memory:d0000000-dfffffff memory:e5010000-e501ffff" This way more info than the command showed in he other post and as far as I can tell right. This doesn't look to me like a laptop video would list? I also see this command xrandr, it reports this: xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024 default connected 1280x1024+0+0 0mm x 0mm 1280x1024 0.0* 1024x768 0.0 800x600 0.0 640x480 0.0 This is what shows in displays for resolutions but only the 1280x1024 works the others produce tearing in the video. Also I should have mentioned 3D mode does not work. I have tried ATI/AMD drivers the new one won't load and older ones won't work. I found out the newer driver no longer supports the 9550.

• Game programming : C# or C++?

  - by Chronix

  Ok so the faq says : "What language should I learn next? (Unless you have a specific requirement and don't know which language meets that requirement.)" so I guess this is not against the rules of questions. So, I've decided what I really want is to do Game Programming. So the question is, as a 18 years old who wants to learn self taught programming, what is the most suited programming language between C# and C++? ( I should state that I don't care about unix because I believe windows will be still the most used os ) I know the basics of C++, but none about C#. I know that C++ has more tutorials guides, dlls and stuff like that, while C# doesn't, but it's far easier to learn and to use for a single person to develop a program, but I've read even if the program is obfuscated it's easy to get the source of it. Well, I kinda want to focus on basic a lot first, I must say that I have a preference for C++ just because it feels more suitable to me, but I must consider that I work alone.. So even if I like it, it may not be the best thing to do. I am really not sure of which one to go for, i've read a lot of threads on various websites and it looks like C# is becoming more popular than C++. But yeah, that said, I also specified I want to do Game Programming. So I need to know some better points than just "C# is easier because of .net memory handling while C++ isnt" because I couldn't just find it. I hope the thread won't be closed because I've read the faq and I have a specific requirement. Thank you, and if you need more details you're free to ask me, but I think just by saying game programming and that I'd work alone should be enough!

• Is it possible to keep only one Database for both web and desktop applications?

  - by B4NZ41

  I'm experiencing a trouble with my business model, let me explain better. I'm developing a software for 1 year and few months, it's for the food industry, more exactly a software to: Delivery, Take Way, Table Reservation, POS, Accounts Payable and Receivable, Prints(receipt), Kitchen Monitors Orders, Customers Orders Control and Fiscal Area. Well, I had separated the software mainly in two areas, one is web area and the other is desktop area (Used by Admins only) and local installed. 1 - Web Area (Basically do the follow:) Show Catalog with the products Customers Make Orders Customers Pay for the Orders etc ... as mentioned above 2 - Desktop Area Manage Orders Manage Customers Manage Suppliers Manage Accounts Payable and Receivable etc ... as mentioned above The web area is hosted in an online web server (scripts and database are online). The Desktop area is hosted locally in a Linux machine with a local database and local scripts files. My question is: Is it possible to keep only one Database for both applications? If YES, please what is the best approach? Follow my technical specification environment Database: Actually I have two databases working and I would love to keep only one. Operating System: Linux (Kernel 2.6.X and above) or Windows (XP and above) For the Web Area Apache, PHP, Python, Java Script, Shell Script and MySQL. For the Desktop Area: PHP-GTK2, Apache, PHP, MySQL and Shell Script.

• How can I better manage far-reaching changes in my code?

  - by neuviemeporte

  In my work (writing scientific software in C++), I often get asked by the people who use the software to get their work done to add some functionality or change the way things are done and organized right now. Most of the time this is just a matter of adding a new class or a function and applying some glue to do the job, but from time to time, a seemingly simple change turns out to have far-reaching consequences that require me to redesign a substantial amount of existing code, which takes a lot of time and effort, and is difficult to evaluate in terms of time required. I don't think it has as much to do with inter-dependence of modules, as with changing requirements (admittedly, on a smaller scale). To provide an example, I was thinking about the recently-added multi-user functionality in Android. I don't know whether they planned to introduce it from the very beginning, but assuming they didn't, it seems hard to predict all the areas that will be affected by the change (apps preferences, themes, need to store account info somehow, etc...?), even though the concept seems simple enough, and the code is well-organized. How do you deal with such situations? Do you just jump in to code and then sort out the cruft later like I do? Or do you do a detailed analysis beforehand of what will be affected, what needs to be updated and how, and what has to be rewritten? If so, what tools (if any) and approaches do you use?

• Is it a good idea to dynamically position and size controls on a form or statically set them?

  - by CrystalBlue

  I've worked mostly with interface building tools such as xCode's Interface Builder and Visual Studio's environment to place forms and position them on screens. But I'm finding that with my latest project, placing controls on the form through a graphical interface is not going to work. This more has to do with the number of custom controls I have to create that I can't visually see before hand. When I first tackled this, I began to position all of my controls relative to the last ones that I created. Doing this had its own pros and cons. On the one hand, this gave me the opportunity to set one number (a margin for example) and when I changed the margin, the controls all sized correctly to one another (such as shortening controls in the center while keeping controls next to the margin the same). But this started to become a spiders-web of code that I knew wouldn't go very far before getting dangerous. Change one number and everything re sizes, but remove one control and you've created many more errors and size problems for all the other controls. It became more surgery then small changes to controls and layout. Is there a good way or maybe a preferred way to determine when I should be using relative or absolute positioning in forms?

• Thinking about open-sourcing quiz project [closed]

  - by user72727

  I was thinking about starting an open source project. I have a few projects that might work ok as an open project but thought I might dip my toe into the water with a simple quiz project. The idea is you can add questions to a quiz, arrange questions by topic, difficulty or location. Users would hopefully get an interesting quiz, tuned to their ability. At the end they'd get a score and hopefully they might provide either some feedback on the questions or even supply a few questions of their own. I couldn't see a similar project (fame's last words). I have a basic version of the project that gives the user a bunch of questions to answer in 10 minutes. It doesn't currently group the questions into topics, and no feedback is taken. I've also been told the graphical questions don't work on Ipads for some reason. Would this be a suitable project to go open source? I did find various quiz's out there but all seemed rather narrowly focused. I really wanted something that could cover any type of question on any type of subject. I prefer to keep the questions in MySQL but I could see how this might make it more difficult for others to get on board - should I move to data files? How do I proceed? http://www.checkmypages.com/numbers

• how to override ckeditor events [migrated]

  - by joe

  I am new to ckeditor, I have hard time figuring this issue out. due to my html design; if I try to use the link editor dialog while my ckeditor is maximized, it just doesn't show up, I understand that ckeditor is the top most object in my html page and the link dialog comes underneath it. if now I bring ckeditor to its normal state I will be able to see and use the link dialog. my idea is to slightly override the link button click event as follows: if the editor is in full screen mode, bring it back to the normal state. and keep a flag somewhere so that when I close the link dialog, I can decide whether to bring back the ckeditor to a maximized mode again. now this is easy logic except that I do not know how to override the click event of the link button and keep it work as expected. here's what I have: $().ready(function () { var editor = $('#txa').ckeditor(); CKEDITOR.plugins.registered['link']= { init : function( editor ) { var command = editor.addCommand( 'link', { modes : { wysiwyg:1, source:1 }, exec : function( editor ) { if(editor.commands.maximize.state == 1 ){ alert("maximized"); //....here bring back the editor to UN-maximized state and let the link button event click do the default behavior } else { alert("normal state"); } //2 is normal state //1 is maximized } } ); editor.ui.addButton( 'link',{label : 'YOUR LABEL',command : 'link'}); } } }); html part to make the exemple work: <div> <textarea id="txa"> </textarea> </div> TO BE SHORT: http://jsfiddle.net/Q43QP/ if the editor is maximized, bring it to normal state then show the link dialog.

• Securing a Cloud-Based Data Center

  - by Orgad Kimchi

  No doubt, with all the media reports about stolen databases and private information, a major concern when committing to a public or private cloud must be preventing unauthorized access of data and applications. In this article, we discuss the security features of Oracle Solaris 11 that provide a bullet-proof cloud environment. As an example, we show how the Oracle Solaris Remote Lab implementation utilizes these features to provide a high level of security for its users. Note: This is the second article in a series on cloud building with Oracle Solaris 11. See Part 1 here.  When we build a cloud, the following aspects related to the security of the data and applications in the cloud become a concern: • Sensitive data must be protected from unauthorized access while residing on storage devices, during transmission between servers and clients, and when it is used by applications. • When a project is completed, all copies of sensitive data must be securely deleted and the original data must be kept permanently secure. • Communications between users and the cloud must be protected to prevent exposure of sensitive information from “man in a middle attacks.” • Limiting the operating system’s exposure protects against malicious attacks and penetration by unauthorized users or automated “bots” and “rootkits” designed to gain privileged access. • Strong authentication and authorization procedures further protect the operating system from tampering. • Denial of Service attacks, whether they are started intentionally by hackers or accidentally by other cloud users, must be quickly detected and deflected, and the service must be restored. In addition to the security features in the operating system, deep auditing provides a trail of actions that can identify violations,issues, and attempts to penetrate the security of the operating system. Combined, these threats and risks reinforce the need for enterprise-grade security solutions that are specifically designed to protect cloud environments. With Oracle Solaris 11, the security of any cloud is ensured. This article explains how.

• Managing game objects/components

  - by Xeon06

  Good day everyone, By far the biggest problem that has always dawned on my when programming games is how to structure my code. It just becomes an incredible mess after a while. The reason for that is because I have no idea how different classes should interact with each other. Let's have an example. Say I have a class Player, a class PlayerInput and a class Map. The player class contains information as to the location of the player, whereas the player input class handles changing that location, but by first making sure it's within a walkable area from the map class. How to structure this? My usual approach is to pass those components as parameters in the constructors of the parameters that need them, like so: var map = new Map(); var player = new Player(); var input = new PlayerInput(player, map); The problem with that is that it quickly gets messy, when you add new components you have to go through your constructors and update them, and it doesn't work well if you have mirroring references: var physics = new Physics(input); //Oops, doesn't work var input = new Input(physics); So, how do you guys usually manage this? Thanks.

• What is the standard way of using Q15 values?

  - by Alex

  To process 8-bit pixels, to do things like gamma correction without losing information, we normally upsample the values, work in 16 bits or whatever, and then downsample them to 8 bits. Now, this is a somewhat new area for me, so please excuse incorrect terminology etc. For my needs I have chosen to work in "non-standard" Q15, where I only use the upper half of the range (0.0-1.0), and 0x8000 represents 1.0 instead of -1.0. This makes it much easier to calculate things in C. But I ran into a problem with SSSE3. It has the PMULHRSW instruction which multiplies Q15 numbers, but it uses the "standard" range of Q15 is [-1,1-2?¹5], so multplying (my) 0x8000 (1.0) by 0x4000 (0.5) gives 0xC000 (-0.5), because it thinks 0x8000 is -1. This is quite annoying. What am I doing wrong? Should I keep my pixel values in the 0000-7FFF range? This kind of defeats the purpose of it being a fixed-point format. Is there a way around this? Maybe some trick? Is there some kind of definitive treatise on Q15 which discusses all this?

• Can I eventually consider myself a professional developer if I don't have a CS degree? [on hold]

  - by heltonbiker

  Question first, context later: If I am a dedicated, self-taught programmer, always seeking top-quality books AND READING THEM, while successfully applying all that new knowledge into my current work, could I call myself (and offer my work as) a PROFESSIONAL developer? How limiting (or how common) that is nowadays? I am afraid that, no matter how hard I study and practice, it could be too difficult to compete with "actual", college graduated developers, and potential employers might have doubts investing in an "undergraduated" person. Now, context: My former profession is from healthcare sector, then I studied mechanical engineering (quit in the middle), then I studied product design (master degree), and I ended up working (very happily) at an engineering company that manufactures medical devices. For more than two years now my main activity in this company is software development. The devices contain software, and we gave up hiring software development (domain knowledge needed, too much communication cost). My current company sees a lot of value in what I do, but I cannot afford the risk of depending on this single company for the rest of my life, you get it. But a lot of job offers require some minimal formal education, usually a CS degree. Fact is that I am sure this is my target profession, I don't plan to go to another area, it is a pleasure to dive into books that normal people would consider unreadable, but I'm 36 years old and can't see going back to college as a viable alternative.

• decouple software components via nameconvention

  - by csteinmueller

  I'm currently evaluating alternatives to refactor a drivermanagement. In my multitier architecture I have Baseclass DAL.Device //my entity Interfaces BL.IDriver //handles the dataprocessing between application and device BL.IDriverCreator //creates an IDriver from a Device BL.IDriverFactory //handles the driver creation requests Every specialization of Device has a corresponding IDriver implementation and a corresponding IDriverCreator implementation. At the moment the mapping is fix via a type check within the business layer / DriverFactory. That means every new driver needs a) changing code within the DriverFactory and b) referencing the new IDriver implementation / assembly. On a customers point of view that means, every new driver, used or not, needs a complex revalidation of their hardware environment, because it's a critical process. My first inspiration was to use a caliburn micro like nameconvention see Caliburn.Micro: Xaml Made Easy BL.RestDriver BL.RestDriverCreator DAL.RestDevice After receiving the RestDevicewithin the IDriverFactory I can load all driver dlls via reflection and do a namesplitting/comparing (extracting the xx from xxDriverCreator and xxDevice) Another idea would be a custom attribute (which also leads to comparing strings). My question: is that a good approach above layer borders? If not, what would be a good approach?

• How similiar should the environments of PreProd and Prod be?

  - by RoboShop

  I've just recently been on a project and during the release, we realized that it didn't work in Production. It works in all other environments but because we have a separate release team, and we cannot set up the servers and environments ourselves, we have no visibility of the configuration on them. We suspect that Prod has some user permissions in its account or IIS settings that are different, so we are working though it now. So I think this whole thing has been a learning experience for me and I don't want the same thing repeated again. I would like to ask, how different should these environments be? I always thought that PreProd should be an identical copy to the Prod environment using a copy of the same database, using a copy of the same user account, should be installed on the same servers etc. But how far should I take it? If the web site is externally facing, should PreProd be externally facing? What if the website has components that don't require a user account or password to navigate to? Is it still okay to expose it to the outside world?

• Accidentally Changed Dual Monitor Setup and don't know how to reset it

  - by user203783

  I have a dual monitor setup with my laptop and an external Asus monitor running under Ubuntu 11.10. When I first started using Ubuntu, it synced both screens. What showed up on my laptop showed up on my eternal monitor. Last night, I accidentally knocked the HDMI cable from its port (not that unusual in the tight space I work in). When I plugged it back in, as usual, the external monitor only displayed my wallpaper. Usually, I just restart Ubuntu and it resets, but last night what I now realize was the display console came up and somehow I changed the setup. Now the two screens show different jobs so to speak. Also, the external monitor doesn't display the ribbon, making switching between Firefox tabs and windows or apps jarring. I write for a living and need to quickly check bits of research, notes or sources while writing and the extra switching between mouse pad and external mouse to get one or the other screen to respond interrupts my work flow. The only technical help I can offer is when the display console popped up, the graphical representation of the screens was that the external screen appeared layered over by about one-quarter of the laptop screen. Again, these were icons. I tried to replicate that after I obviously screwed things up. If someone could help. I would appreciate it. If I have to use terminal, that's fine. I started using computers for writing back when they were green DOS prompts. There's a certain elegance to prompt commands to me. Maybe it's the writer in me. Again, if anyone can help me return my screens to sync under Ubuntu 11.10, I would greatly appreciate it.

• One of my VMs went boom using Virtual Box and how it got fixed

  - by Enrique Lima

  I am running an HP Envy 15, 16GB and 500GB (7200 RPM) Hard drive. Had a VM configured from another environment, created the virtual machine config file on Virtual Box, everything seemed ok. Fired it up, and it was  s   l   o   w, it took close to 10 minutes for it to load, and about 5 more to see Windows was in the process of loading before the BSOD.  Thought, maybe, just maybe it will not happen again … oh was I wrong. Frustration had already hit an all time high with this configuration and the number of issues I’ve had. How I did the troubleshooting … The best thing to do (IMO) is to step back, and gather your tools to debug this situation. Tools:  Virtual Box command line tools, Windows Debug. Virtual Box comes with a pretty good set of tools to examine, migrate and overall tasks to deal with VMs. The firs step:  use VBoxManage to prevent the VM from rebooting after the error to get enough time to really dig into the BSOD issue. Command used:   VBoxManage setextradata VMNAME "VBoxInternal/PDM/HaltOnReset" 1 Once this was done, the error reported was an “Inaccessible boot device” coming from a “Stop – 7B” type of error on the BSOD. The issue I had with this, my VM was configured to use a virtual SATA controller, and thought Windows 2008 R2 would handle this fine … again wrong!  Because the integration tools from the other product where wanting to take effect that was throwing everything off. The fix The fix was almost handed to me, edited the configuration for the VM, removed the SATA controller from it, added the virtual hard drive under an IDE controller, boot up and voilà … it works! I was then able to install the Virtual Box guest tools and such, but have decided to favor “keep on working” over “let’s try SATA again”

• Creating dynamic plots

  - by geoff92

  I'm completely new to web programming but I do have a programming background. I'd like to create a site that allows users to visit, enter some specifications into a form, submit the form, and then receive a graph. I have a few questions about this, only because I'm pretty ignorant: Is there a good framework I should start in? I know a lot of java, I'm okay with python, and I learned Ruby in the past. I figure I might use ruby on rails only because I hear of it so often and I think I've also heard it's easy. If anyone has some other recommendation, please suggest. The user will be entering data into a form. I'm guessing the request they'll be making should be one of a GET request, right? Because I don't intend for any of the data they're entering to modify my server (in fact, I don't intend on having a database). The data the user inputs will be used to perform calculations involving lots of matrices. I've written this functionality in python. If I use ruby on rails, should it be instead written in Ruby? Somewhere I've heard that you can either place the load of the work on your server or on the client's computer. Since the code performs heavy math, which option is preferable? How do I alter the setup to either make the client do the work or my server? Should I be using a "cgi-bin"? In the code that I have now, I use matplotlib, a python library, and then "show" the plot in order to see the graph. I specify the x and y limits, but I am able to "drag" the graph in order to see more data within the plot window. Ultimately, I want a graph to be shown on my site with the drag functionality. Is this possible? What if the client drags the graph so far, more computations must be made? Thanks!

• High-level description of how experimental C++ features are developed?

  - by Praxeolitic

  Herb Sutter in a video answers a question about the concepts proposal considered for C++11 and from his remarks it sounds like multiple groups offered prototype implementations but all of them left concerns about slow compile times. The comment surprised me because it suggests that, at least in some cases, the prototypes being developed are not just proofs of concept -- they're even expected to perform. All the work that must take has me curious. For mature languages, especially C++, how are experimental language features developed? Is it much different from developing a compiler that implements a standard? Does a developer have a sense of if it will work and perform or even if it ever could? What are the most time consuming parts and are any parts surprisingly easier than one might expect? The question is not what does the C++ standards committee do, but rather the part that comes before. When an experimental implementation for a proposal is being put together and there aren't any completely solidified rules, how is the sausage made? I'm not a professional compiler developer nor do I expect answers with step by step accounts. I'd like a high-level idea of how this would be done or if there are any general patterns at all. I don't know what to expect from the answers but even if there are no rules to the process and the small number of people who do this just cowboy it and then, for stuff that worked out, write up the "official version" as a proposal, that answer would still be informative.
