• How to convince an employer to move to VB.Net for new development?

  - by Dabblernl

  Some history:For the last six months I have been employed at a small firm with just three programmers, my employer among them. The firm maintains two programs written in VB6. I am asssigned as the lead programmer to one of these. In the last six months I did some maintenance and bug hunting, but created some new functionality too. I had an interview last december, which was favorable, and my contract was prolonged. I am very happy with this course of events as I only obtained a .Net certification a year ago and have no other qualifications (in the field of coding, that is). It is my strong opinion that, while migration of the existing program to .Net is advisable, it is paramount that from now on the new functionality should be written in VB.Net class libraries. After some study I found out how simple it is to integrate .Net class libraries into the VB6 development environment and how easy it is to add their functionality to existing installations by using application manifests. So, I have decided that now is the moment to roll up my sleeves and try and convince my employer that he should let me develop new code in VB.Net, using VB6 for maintenance only. We get along quite well, but I think I am going to need all the ammunition I can get to convince him. Any arguments, preferably backed up up ones, are very welcome, even arguments to dissuade me ;-)

• Installing ubuntu 12.04 on macbook pro9,2

  - by stariz77

  I seem to have tried all the various suggested methods for installing ubuntu on a mbp, but can't seem to get anything that works and was wondering if anyone has run into any new problems with the latest non-retina models? I have a core i7 in my macbook, and model identifier is MacBookPro9,2. I have partitioned my HD using disk utility and have 700gig free space ready for the install (I haven't removed OSX Lion, it is still there in a 50gig partition). Problem: I am just getting a blank screen with a blinking cursor (unresponsive) in the top left whenever I boot from the disk. I left it for 20 minutes and nothing ever happened. This was without any boot manager, just holding "c" on startup. Attempted remedies: I have downloaded the 64 ubuntu iso from their site 3 times now and burned 4 separate discs to rule out some kind of corruption or burn error. I burned one in OSX Lion 10.7.4 and 3 on my windows 7 pc. I tried holding "alt" instead and then navigating to the windows disc to boot. Same thing happens, blank blinking unresponsive cursor. I also tried going to the EFI disc which actually brings up a menu (after saying "error prefix is not set") asking if I want to install ubuntu, test for errors or partition. All three options lead me to an unresponsive blank screen (some without cursors). I downloaded and installed rEFIt and if I hold "alt" on startup a linux penguin (Boot Linux from CD) appears in my boot options, along with the apple boot, and two others that I'm not sure of: "Boot EFI\boto\bootx64.efi from" and "Boot Legacy OS from". The "Boot Linux from CD" just takes me to the blank blinking cursor screen; again, I left if for 10+ minutes and nothing. I heard that the detection of the graphics card might be a problem and that I need change to nomodeset, but I have tried pressing F6 in all of the boot menus listed above and no options appear. Does anyone have any other suggested routes or can you see what I might have done wrong?

• Functional Programming, JavaScript and UI - some neophyte questions

  - by jamesson

  This has been discussed in other threads, however I am hoping for some comments relevant to UI and an explanation of some vitriol I had flung my way in a Certain IRC Channel Which shall remain nameless. In the discussion here, the comments in the accepted answer suggest that I approach the given code from a functional perspective, which was new to me at the time. Wikipedia said, among other things, that FP "avoids state and mutable data", which includes according to the discussion global vars. Now, being that I am already pretty far along in my project I am not going to learn FP before I finish, but... How is it possible to avoid global vars if, for instance, I have a UI whose entire functionality changes if a mousebutton is down? I have a number of things like this. Why was there a strong negative reaction in the Certain IRC channel to implementing FP in JS? When I Brought up what seemed to me to be supportive comments by Crockford, people got even madder. Now, this being IRC there is no rep system, but they at least gave indication of having read TGP (which I haven't gotten to yet) so I'm assuming they're not idiots. Many thanks in advance Joe

• Ubuntu 12.04 Very slow especially with Android Studio

  - by Dew

  I have an old laptop with the following specification: Memory: 485 MiB, Processor: Genuine intel CPU T2300 @ 1.66 GHz ×2, OS Type: 32 bit, Disk: 78.1 GB, I installed on it Ubuntu 12.04 LTS and I noticed that the overall system is very slow in responding. I tried to search about that in the internet and I found some articles talking about how to make Ubuntu 12.04 LTS run fast I applied all what they said including download LXDE desktop environment and then nothing different in the system response time. Then I need to develop some android applications so, I download Android Studio (Beta) 0.8.6. The problem became worse than before whenever I tried to open the Android Studio the screen is frozen for some minutes then it took time to download the projects and initialize the work space also, when I tried to move the cursor he is move very slowly. When I tried to run my first application on the AVD it took three hours and still not run yet. I delete the Android Studio and install it again several times, I was trying to solve the problem but still nothing change. Please if you have any suggestions that may help me make my laptop and Android Studio work faster I will appreciate it for you. Thank you in advance.

• Solving the puzzle in javascript [on hold]

  - by Gandalf StormCrow

  I've recently try to brush up my javascript skills, so I have a friend who gives me puzzles from time to time to solve. Yesterday I got this : function testFun() { f = {}; for( var i=0 ; i<3 : i++ ) { f[i] = function() { alert("sum='+i+f.length); } } return f; } Expected Results: testFun()[0]() should alert “sum=0” testFun()[1]() should alert “sum=2” testFun()[2]() should alert “sum=4” I did this which does like requested above: function testFun() { var i, f = {}; for (i = 0; i < 3; i++) { f[i] = (function(number) { return function() { alert("sum=" + (number * 2)); } }(i)); } return f; } Today I got new puzzle : Name everything wrong with this javascript code, then tell how you would re-write it. function testFun(fInput) { f = fInput || {}; // append three functions for( var i=0 ; i<3 : i++ ) { f[i] = function() { alert("sum='+i+f.length); } } return f; } // Sample Expected Results (do not change) myvar = testFun(); myvar[0](); // should alert “sum=0” myvar[1](); // should alert “sum=2” testFun(['a'])[2](); // should alert “sum=5”`enter code here How do I accomplish the third case testFun(['a'])[2]()? Also could my answer from yesterday be written better and what can be improved if so?

• Deploying InfoPath forms &ndash; idiosyncrasies

  - by PointsToShare

  Well, I have written a sophisticated PowerShell script to expedite the deployment of InfoPath forms - .XSN file.  Along the way by way of trial and error (mostly error and error), I discovered a few little things. Here they are. •    Regardless of how the install command is run – PowerShell or the GUI in Central Admin – SharePoint enwraps the XSN inside a solution – WSP, then installs and deploys the solution. •    The solution is named by concatenating “form-“ with the first 16 characters (or less if the file name is shorter than 16) of the file name and the required WSP at the end. So if the form name was MyInfopathForm.xsn the solution name will be form-MyInfopathForm.wsp, but for WithdrawalOfRequestsForRefund.xsn it will be named form-WithdrawalOfRequ.wsp •    It only gets worse! Had there already been a solution file with the same name, Microsoft appends a three digit number to the name, like MyInfopathForm-123.wsp. Remember a digit is a finger, I suspect a middle finger, so when you deploy the same form – many versions of it, or as it was in my case – testing a script time and again, you’ll end up with many such digit (middle finger) appended solutions, all un-deployed except the last one. This is not a bug. It’s a feature!   Well, there are ways around it. When by hand, remove the solution from the solution store before deploying the form again. In the script I do the same thing. And finally - an important caveat; Make sure that all your form names are unique in the first 16 characters. If you also have a form with the name forWithdrawalOfRequestForRelief.xsn, you’re in trouble! That’s all folks!

• How do i impress employers with my resume?

  - by acidzombie24

  I built a entire website from scratch in 10days which looks and feels professional with the site being unique. The site has features like logging in, sending activation emails, tag/content search (lucence.net), syntax highlighting (prettify) and a diff (one of the js diffs), markup for comments all on this site and autocomplete in a textbox (remember, 10days). I wrote i have 5+ years of C# experience (i could lie and say more but smart employers will know its only 8 years old and 1.1 is very different from what we use now). I had employers REPEATEDLY say they are looking for someone who has more C# experience... wtf. Maybe they don't read my CV, maybe they dont believe it or ignore me because i am not yet a graduate. I laughed when i first read Steve Yegge The Five Essential Phone Screen Questions as i knew all of that (although i still never used graph datastruct nor know much about it). I'm pretty sure competency wise i can do the job. I am also positive no one noticed i have markup, a diff, autocomplete nor email activation/forget password (i offer a test user account). So maybe my site/example work isnt impressive bc you dont realize what is in it. In short i dont think they read my CV or notice my site. How do i impress employers? PS: The problem is i dont get to the interview. I had one and ruined it by speaking too technical to the PM because i was nervous. The other 25+ jobs either didnt contact me or was kind enough to send a rejection email.

• Laptop battery charging capacity reduced to 52%

  - by omjaijagdish

  I have been using Ubuntu 11.04 on DELL Inspiron 14R (N5010) laptop for last three months. Before I switch to ubuntu my laptop battery used to give 2.5 hrs to 3 hrs back-up.

• Smoothing rotation

  - by Lewis

  I've spent the last three days trying to work out how to rotate a sprite smoothly depending on the velocity.x value of the sprite. I'm using this: float Proportion = 9.5; float maxDiff = 200; float rotation = fmaxf(fminf(playerVelocity.x * Proportion, maxDiff), -maxDiff); player.rotation = rotation; The behaviour is what I required but if the velocity changes rapidly then it will look like the sprite will jump to face left or jump to face right. I'll go into the behaviour in a little more detail: 0 velocity = sprite faces forwards negative velocity = sprite faces left depending on value. positive velocity = sprite faces right (higher velocity the more it faces right) same as above. I've read about using interpolation rather than an absolute angle to rotate it to but I don't know how to implement that. I have a physics engine available. There is one other way to get around this: to use += on the rotation angle. The thing is that I would then have to change the equation to produce positive and negative values then to make sure the sprite faces 0 once it reaches 0 velocity again. If I add that in now, it keeps the previous angle even after the velocity has dropped / is dropping. Any ideas/code snippets would be greatly appreciated.

• Why is Python used for high-performance/scientific computing (but Ruby isn't)?

  - by Cyclops

  There's a quote from a PyCon 2011 talk that goes: At least in our shop (Argonne National Laboratory) we have three accepted languages for scientific computing. In this order they are C/C++, Fortran in all its dialects, and Python. You’ll notice the absolute and total lack of Ruby, Perl, Java. It was in the more general context of high-performance computing. Granted the quote is only from one shop, but another question about languages for HPC, also lists Python as one to learn (and not Ruby). Now, I can understand C/C++ and Fortran being used in that problem-space (and Perl/Java not being used). But I'm surprised that there would be a major difference in Python and Ruby use for HPC, given that they are fairly similar. (Note - I'm a fan of Python, but have nothing against Ruby). Is there some specific reason why the one language took off? Is it about the libraries available? Some specific language features? The community? Or maybe just historical contigency, and it could have gone the other way?

• Finding back to an old project that was turned upside-down by the developer. Your workflow?

  - by Kreativrandale

  after some time I'm asked to work on a heavy web-project I did (layout, html/css) about a year ago. There are some changes that have to be made, basically some css and js stuff. By now the whole project was turned upside down by the developer. It gives me a hard time to connect to the work of him, especially because my old files and file-structure won't work anymore. Thats why I need a up-to-date working-environment, but I don't want to change the files on the server directly. Need some testing and improving while doing this. So, what is your workflow in such a case? Thought about copying the whole/parts of the server to a own homeserver. But even that will be a big task for me (I'm more the front-end-guy). Would be great if theres a way to shrink it down (php, mysql,...), since I only need to change some css/html javascript. Are there any tools available? Love to hear how you handle such situations. Thanks a lot!

• How to ask developers to think about high resolution screens

  - by WhiteWind

  I just got a ASUS N56VZ laptop, and it`s all good, but the screen resolution 1920x1080px. I am not asking, how to scale ui elements. If someone is interested I have found some tricks: increase font size in system settings increase unity dock size in MyUnity or system settings in modern Ubuntu versions. tweak userChrome.js of FireFox to make buttons|panels|icons larger add DefaultZoomLevel extension to FireFox to make it zoom pages initially. But all of it is miserable, because there are some big bugs: window decoration elements are way too small to pick them with mouse. I can't scale window easily and I can't position my cursor fast on the close|maximize buttons. Tuning lines like in sound volume dialog are hardly clickable at all. Unity top panel (status panel & tray) hardly can contain the bigger font, so it looks ugly, but icons are still the same. Sometimes I can`t read text, as it is cropped (and I cant scale some dialogs as it has fixed size) Chromium is not usable at all (ok, it's not Ubuntu problem, but the problem still exists) JAVA applications are not scalable (same as above) In FF I am able to get descent results in most cases, but multiplication of system font increase and browser font increase makes system controls (combobox, lists, drop down lists) extremely big, so I cant even control the zoom level on the page. IMHO, we should post a bug report (but what kind of bug?) and vote for it! The problem is even deeper, but at least we should ask developers to think about it. So my question is: how can I post a report (the right words and right place) and how can we (who already has that problem, or who want it to be solved before hardware upgrade) vote for faster solution. Any ideas?

• How can I play 24Bit 96000Hz vinyl rips?

  - by Peter

  I am getting music through the Nvidia HDMI but it is all down-sampled to 44000Hz. I have spent at least 3 hours searching for an answer yesterday. I use Pulse Volume and I even changed the default settings in the Pulse folder to 96000 but it does not work. Though 5.1 sound works perfectly. They all work well in Windows 7, but I prefer to use Ubuntu. All the config files for all the programs are in the etc folder, then look in the pulse folder, and there are 3 three files, 2 of these I changed the permissions and I changed 16 and 44000 to 24 and 96000 as I had read in another forum, but it worked for them and not for me. Though 5.1 works as I have special mp4 file that can check each channel. I did alot of restarts and checking after these changes as nothing had happened, my amp tells me the freq of the signal, which does work which I have tested on Windows 7. I have also gone to systems to download the latest driver for mu Nvidia card. But even if it does not work, I guess I can always play Cd's. But I think my player have become more unstable since I changed the configs, so I may uninstall and install Pulse Volume Control again.

• Maintaining C/C++/Java skills as a web developer

  - by wwwuser

  When I was in college I learned how to program in C, C++, and Java. Currently, I'm a web developer using front end and back end technologies (HTML/CSS/JS, PHP, MYSQL). While the sorting algorithms and OOP concepts that I learned in college can be applied to web development, I'm looking for ways to keep up my knowledge of all languages. I enjoy programming in C-Style (C/C++/Java) languages and front-end/back-end technologies. Unfortunately, there aren't many options to use C-style languages to build websites. However, I would like to keep up my knowledge and skills in the languages I learned in college as I know they will continue to help me with my growth. What resources are available to keep challenging myself in C-style languages that are relevant to web development? Would contract work for C-style languages be beneficial? Are there sites that offer algorithm challenges? Any help is appreciated. I'm also interested in how others that have asked themselves this have solved this problem.

• Working with Google Webmaster Tools

  - by com

  My first question is about Crawl errors in Google Webmaster Tools. Crawl errors is devided into few sections. One of them is HTTP. I assume that all broken links in HTTP was somehow found by crawler, this is not the links from sitemap. If this was found by scanning all sitemap pages for links, why it doesn't mention what was the source page, like in sitemap section with column Linked From. And what the meaning of Linked From, I thought if the name of section is sitemap, therefore all URLs should be taken from sitemap, so why there is Linked From? The second question, what is the best way to trreat searching on the site. How come the searching result page are getting indexed? Because of the fact that all searching result page are getting indexed, I have to many page in Linked From. What's the right practice? Question three: In order to improve response time in WMT, can I redirect all crawler's requests to designated free web server? Is this good practice? Question four: How should I treat Google Analytics Code (with parameters PageView, PageLoadTime), in the case user request non existing page, should I render Google code or not? Right now I use Google Analytics Code on the common template page, such that every page, also non existing page with error message contains Google Analytics Code, it seems like it has influence on WMT.

• Good sysadmin practise?

  - by Randomthrowaway

  Throwaway account here. Recently our sysadmin sent us the following email (I removed the names): Hi, I had a situation yesterday (not mentioning names) when I had to perform a three way md5 checksum verification over the phone, more than once. If we can stick to the same standards then this will save any confusion if you are ever asked to repeat something over the phone or in the office for clarification. This is of particular importance when trying to speak or say this over the phone … m4f7s29gsd32156ffsdf … that’s really difficult to get right on a bad line. The rule is very simple: 1) Speak in blocks of 4 characters and continue until the end. The recipient can read back or ask for verification on one of the blocks. 2) Use the same language! http://en.wikipedia.org/wiki/Phoenetic_alphabet#NATO Myself, xxx and a few others I know all speak the NATO phonetic alphabet (aka police speak) and this makes it so much easier and saves so much time. If you want to learn quickly then all you really need is A to F and 0 to 9. 0 to 9 is really easy, A to F is only 6 characters to learn. Could you tell me if forcing the developers to learn NATO alphabet is a good practise, or if there are ways (and which ways) to avoid being in such a situation?

• Is it viable to make a port from a C++ application to Java through LLVM

  - by Javier Mr

  how viable is it to port a C++ application to Java bytecode using LLVM (I guess LLJVM)? The thing is that we currently have a process written in C++ but a new client has made mandatory to been able to run the program in a multiplatform way, using the Java Virtual Machine with obviously no native code (no JNI). The idea is to be able to take the generated jar and copy then to different systems (Linux, Win, 32 bits - 64 bits) and it should just work. Looking around looks like it is possible to compile C++ to LLVM IR code and then that code to java bytecode. There is no need of the generated code to be readable. I have test a bit with similar things using emscripten, this takes C++ code and compile it to JavaScript. The result is valid JS but totally unreadable (looks like assambler). Does anybody done a port of an application from C++ to Java bytecode using this tecnique? What problems could we face? Is a valid approach for production code? Note: I am aware that currently we have some non standard C++ and close source libraries, we are looking to removing this non standard code and all close source libraries and use Free Libre Open Source Software, so lets suppose all code is standard C++ code with all code available at compile time. Note: It is not an option to write portable C++ code and then compile it to the desired target platform, the compiled program must be mltiplatform thus the use of JVM (right now we are not looking in similar solutions but Python or other language base, but i would also like to heard about it)

• Problems after installing a plethora of updates

  - by box

  yesterday I decided to install 32-bit Ubuntu on my 64-bit desktop, first of all, is that a problem? After installing, i had around 270 updates to install, according to the update manager. I was having trouble launching a game with WINE, so I thought updating might help. After updating, I restarted my computer, and after a long while it showed me my desktop and the icon's on it, but I didn't get anything else. I didn't have the "taskbar" (not sure what it's called, sue me) on the left side, nor the bar at the top. I also received an error message saying some program had stopped working. I decided to restart my computer again, and that was when it told me that i have to re-configure my drivers, or run in "Low Graphics" mode for one session, amongst other options. Well, I decided to try to revert to the "basic video drivers", which was an option it gave. Restarting the computer gave me the same problem as in the second paragraph. After a few more restarts and a night of restless sleep, here I am trying to start my computer again, only to receive a black screen, and my monitor "going to sleep". I'm sort of stumped here, being new to Ubuntu (desktop, at least) and I really hope this gets fixed without me having to install Ubuntu on yet another partition (I have three other partitions for various things already) tl;dr: Black screen on boot after installing updates.

• More NASM with GVim

  - by MarkPearl

  Today I am bashing around with nasm again… some useful things I found… Set the current working directory of gvim to the current file path I have found setting the current working directory of gvim to the file location is very useful, especially if you are wanting to use commands in gvim to run your compiled code. It can be done by typing in the following in the command mode in gvim… cd %:p:h Once you have set it, you can use the ! to run commands you would normally run in the dos shell.. e.g. !dir Compiling code to make an executable There are three thing you need to specify to compile a basic file in name, they are… The output file format The output file name The source file name An example of this would be the following (where you have a file called temp.asm which is the source file) nasm –f bin temp.asm –o temp.com Output file format The –f specifies the output file format (in this case a binary file). To get a list of the available output file formats you can type nasm –hf (for my installation bin is the default, in which case I can omit it) Output file name This is just the name you want the compiled file to be called. For windows machines I specify .com as my default format.

• Trying to wrap my head around class structure for domain-specific language

  - by svaha

  My work is mostly in embedded systems programming in C, and the proper class structure to pull this off eludes me. Currently we communicate via C# and Visual Basic with a large collection of servos, pumps, and sensors via a USB-to-CAN hid device. Right now, it is quite cumbersome to communicate with the devices. To read the firmware version of controller number 1 you would use: SendCan(Controller,1,ReadFirmwareVersion) or SendCan(8,1,71) This sends three bytes on the CAN bus: (8,1,71) Connected to controllers are various sensors. SendCan(Controller,1,PassThroughCommand,O2Sensor,2,ReadO2) would tell Controller number 1 to pass a command to O2 Sensor number 2 to read O2 by sending the bytes 8,1,200,16,2,0 I would like to develop a domain-specific language for this setup. Instead of commands issued like they are currently, commands would be written like this: Controller1.SendCommand.O2Sensor2.ReadO2 to send the bytes 8,1,200,16,0 What's the best way to do this? Some machines have 20 O2 Sensors, others have 5 controllers, so the numbers and types of controllers and sensors, pumps, etc. aren't static.

• Creating deterministic key pairs in javascript for use in encrypting/decrypting/signing messages

  - by SlickTheNick

  So I have been searching everywhere and havn't been able to find anything with the sufficient information I need.. so Im a bit stumped on this one at the moment What I am trying to do is create a public/private key pair (like PGP) upon a users account creation, based on their passphrase and a random seed. The public key would be saved on the server, and ideally the private key would never be seen by the server whatsoever. The user could then sign in, and send a message to another user. Before the message is sent, the senders key pair would be re-generated on the fly based on their credentials (and maybe a password prompt) and used to encrypt the message. The receiver would then use their own re-generated private key to decrypt said message. The server itself should never see any plaintext passwords, private keys or readable messages. Bit unsure how on how I could go about implementing this. Iv been looking into PGP, specifically openPGP.js. The main trouble I am having is being able to regenerate the key-pair based off a specific seed. PGP seems to have a random output even if the inputs are the same. Storing the private key in a cookie or in HTML5 storage or something also isnt really an option, too unreliable. Can anyone point me in the right direction?

• What to do as a new team lead on a project with maintainability problems?

  - by Mr_E

  I have just been put in charge of a code project with maintainability problems. What things can I do to get the project on a stable footing? I find myself in a place where we are working with a very large multi-tiered .NET system that is missing a lot of the important things such as unit tests, IOC, MEF, too many static classes, pure datasets etc. I'm only 24 but I've been here for almost three years (this app has been in development for 5) and mostly due to time constraints we've been just adding in more crap to fit the other crap. After doing a number of projects in my free time I have begun to understand just how important all those concepts are. Also due to employee shifting I find myself to now be the team lead on this project and I really want to come up with some smart ways to improve this app. Ways where the value can be explained to management. I have ideas of what I would like to do but they all seem so overwhelming without much upfront gain. Any stories of how people have or would have dealt with this would be a very interesting read. Thanks.

• Translating an object along its heading

  - by Kuros

  I am working on a simulation that requires me to have several objects moving around in 3D space (text output of their current position on the grid and heading is fine, I do not need graphics), and I am having some trouble getting objects to move along their relative headings. I have a basic understanding of vectors and matrices. I am using a vector to represent their position, and I am also using Euler Angles. I can translate one of my entities with a matrix along whatever axis, and I can alter their heading. For example, if I have an entity at (order is XYZ) 1, 1, 1, with a heading of 0, I can apply a translation matrix to get them to talk to 1, 1, 2 fine. However, if I change their heading to 270, they still walk to 1, 1, 3, instead of 2, 1, 2 as I desire. I have a feeling that my problem lies in not translating my matrix from world space to object space, but I am not sure how to go about that. How can I do this? Addition: I am using 3D vectors to represent their current position and their heading (using the three euler angles). For now, all I want to do is have an entity walk in a square, reporting their current position at each step. So, assuming it starts at 10, 10, 10 I want it to walk as follows: 10,10,10 -> 10, 10, 15 10, 10, 15 -> 5, 10, 15 5, 10, 15 -> 5, 10, 10 5, 10, 10 -> 10, 10, 10 My 1 Z unit translation matrix is as follows: [1 0 0 0] [0 1 0 0] [0 0 1 1] [0 0 0 1] My rotation matrix is as follows: [0 0 1 0] [0 1 0 0] [-1 0 0 0] [0 0 0 1]

• More productive alone than in a team?

  - by Furry

  If I work alone, I used to be superproductive, if I want to be. Running prototypes within a day, something that you can deploy and use within a few days. Not perfect, but good enough. I also had this experience a few times when working directly with someone else. Everybody could do the whole thing, but it was more fun not to do it alone and also quicker. The right two people can take an admittedly not too large project onto new levels. Now at work we have a seven person team and I do not feel nearly as productive. Not even nearly. Certain stuff needs to be checked against something else, which then needs to also take care of some new requirement, which just came in three days ago. All sorts of stuff, mostly important, but often just a technical debt from long ago or misconception or different vocabulary for the same thing or sometimes just a not too technically thought out great idea from someone who wants to have their say, and so on. Digging down the rabbit hole, I think to myself, I could do larger portions of this work faster alone (and somewhat better, too), but it's not my responsibility (someone else gets paid for that), so by design I should not care. But I do, because certain things go hand in hand (as you may experience it, when you done sideprojects on your own). I know this is something Fred Brooks has written about, but still, what's your strategy for staying as productive as you know you could be in the cubicle? Or did you quit for some related reason; and if so where did you go?
