• error: no such partition after 11.10 upgrade to 12.04

  - by Alan King

  -I recently upgraded my 11.10 install to 12.04 LTS and got the above error message upon reboot after a GNU GRUB version ubuntu3 display showing Ubuntu 3.2.0-23-generic pae and other kernels or memory tests to choose from. The upgrade had to be done by CD because the Update Manager did not show the 12.04 upgrade option. After selecting the default install option of upgrading 11.10 to 12.04, I was presented with a screen saying that I had not specified a swap partition. Upon selection the 'back' key, I was taken to a partition page which listed two current partitions (only Ubuntu 11.10 had been installed - no Windoz): an ext4 partition plus a small 1.8GB partition. I double clicked the small partition and selected it as the swap partition even though I wondered at the time why this even came up. I can see the two user folders under home from the file manager screen while runnning 12.04 from the CD but if I try to access either one an error message is displayed saying I do not have permission while I get a loading message in the lower right corner of the window that does not go away. I have two questions: Can I access the user folders prior to recovery via the Terminal? If so, how? How do I fix the GRUB issue?

• How do I connect to a wireless network?

  - by Keith Groben

  I just installed 10.10 x64 and cannot even find my wireless network let alone connect to it. I've searched all over SE and Ubuntu forums and cannot find out how to do this simple thing.

• Black Screen on pressing back button in libgdx

  - by user26384

  In my game when i touch on advertisements and press back button to return on game the i am getting a black screen. I referred this link. I tried to change IosGraphics.java but the change is not reflected in monotouch project. I did the following : Extracted nightly.zip and opened gdx-backend-iosmonotouch-sources From there I changed IosGraphicsjava. I then made a new jar file gdx-backend-iosmonotouch.jar and replaced it with original jar file in the nightly folder. Compressed all the files from nightly folder in .zip file. Used this .zip file to make a new project throuch gdx-setup-ui.jar. I tried to open my project in monotouch and from com-gdx-backendios.dll i found that the changes in IosGraphics are not being reflected. Am I missing something? How do I solve this? I even tried to open gdx-backend-iosmonotouch-sources.jar with winrar and edit IosGraphics.java and save it. Even this didn't work.

• What credentials should I use to access a Windows share?

  - by JMCF125

  H
  i, I have installed Samba and CIFS and all that, followed a bunch of tutorials, but still I can't access a share in the separate Windows 7 machine. Before I could access a share in Ubuntu from Windows, but although now I can't for whatever reason; the error of the attempt to mount the Windows share is the same: 13, asking for credentials (the computer with Windows is off now, but I can add the exact error message later). In /etc/fstab I have: # ... (help info) ... # <file system> <mount point> <type> <options> <dump> <pass> # ... (mounting points that don't matter for the question) ... //192.168.1.2/C\:/Users/Public/Documents /srv/Z\:/ cifs user=guest,password=,uid=1000,iocharset=utf8 0 0 I also tried options such as username=guest,uid=1000,iocharset=utf8 and guest,uid=1000,iocharset=utf8, which, of course, don't work. What user am I supposed to use? (user=user; username=user; my credentials in the Windows and Ubuntu machines do not work, at least with the syntax I tried - similar to this). Even if this worked it's not actually what I want. I wanted to setup an authentication for any one trying to access the drive (it's currently 777, for the Linux share as well) and put a limit/quota on the share's use (as I see Z:on Windows, it allows for the entire C:drive to be filled). Thank you in advance. I'd be glad if you suggested a way to do this even without the last paragraph.

• Are Java's public fields just a tragic historical design flaw at this point?

  - by Avi Flax

  It seems to be Java orthodoxy at this point that one should basically never use public fields for object state. (I don't necessarily agree, but that's not relevant to my question.) Given that, would it be right to say that from where we are today, it's clear that Java's public fields were a mistake/flaw of the language design? Or is there a rational argument that they're a useful and important part of the language, even today? Thanks! Update: I know about the more elegant approaches, such as in C#, Python, Groovy, etc. I'm not directly looking for those examples. I'm really just wondering if there's still someone deep in a bunker, muttering about how wonderful public fields really are, and how the masses are all just sheep, etc. Update 2: Clearly static final public fields are the standard way to create public constants. I was referring more to using public fields for object state (even immutable state). I'm thinking that it does seem like a design flaw that one should use public fields for constants, but not for state… a language's rules should be enforced naturally, by syntax, not by guidelines.

• An entry-level programmer's best option [on hold]

  - by user134409

  I am facing a puzzle and I am not sure the best way to make a decision. In my spare time besides playing video games I got around to develop some games, nothing fancy, just small projects to get a better grasp at programming. After I finished college and got my BA in Computer Science, I got a job as web developer at a small firm. The next few months were very stressful as I had no previous experience and tried my best to make up for it. But after 6 months my boss told me I was inefficient and not very independent and let me go. To my credit, the help from the senior was very limited, I did learn a lot but I have learned by myself. For example they told me to do a UI in BackboneJS and I took me a while but I got it working (even if it was poorly designed). But I managed to do it all by myself because my senior was very busy and he did not have time even for my questions. Now I have found a new job again in web development but I am very afraid of what is going to happen next. I am afraid because I don't want to take the job and then be fired again after a couple of months, I get the feeling that this will be very bad on my CV, job hopping is like a red flag. They want to hire me but I am aware that they are working with new technologies and maybe I will end up not coping with it. So the question is: Should a entry-level programmer be better off with a starting job in QA, testing and work his way from there? I did learn allot from my first job but it was a moral blow when they decided to fire me. I do have a low self-esteem and I know my skills as a programmer are not that great. But I like programming and want to get better and I want to have a long career in it so that basically my pickle. Thank you in advance for the answers.

• Should I expect my peers to read or practice on a regular basis? [closed]

  - by Joshua Smith

  I've been debating asking this question for some time. Based several of the comments I read in this question I decided I had to ask. This feels like I'm stating the obvious, but I believe that regular reading (of books, blogs, StackOverflow, whatever) and/or practice are required just to stay current (let alone excel) in whichever stack you use to pay the bills, not to mention playing with things outside your comfort zone to learn new ways of doing things. Yet, I virtually never see this from many of my peers. Even when I go out of my way to point out useful (and almost always free) learning material, I quite often get a sense of total apathy from those I'm speaking to. I'd even go so far as to say that if someone doesn't try to improve (or at least stay current), they'll atrophy as technology advances and actually become less useful to the company. I don't expect people to spend hours a day studying or practicing. I have two young kids and hours of practice simply aren't feasible. Still, I find some time; perhaps on the train, at lunch, in bed for a few minutes, whatever. I'm willing to believe this is arrogance or naivete on my part, but I'd like to hear what the community has to say. So here's my question: Should I expect (and encourage) the same from my peers, or just keep my mouth shut and do my own thing?

• How can I test linkable/executable files that require re-hosting or retargeting?

  - by hagubear

  Due to data protection, I cannot discuss fine details of the work itself so apologies PROBLEM CASE Sometimes my software projects require merging/integration with third party (customer or other suppliers) software. these software are often in linkable executables or object code (requires that my source code is retargeted and linked with it). When I get the executables or object code, I cannot validate its operation fully without integrating it with my system. My initial idea is that executables are not meant to be unit tested, they are meant to be linkable with other system, but what is the guarantee that post-linkage and integration behaviour will be okay? There is also no sufficient documentation available (from the customer) to indicate how to go about integrating the executables or object files. I know this is philosophical question, but apparently not enough research could be found at this moment to conclude to a solution. I was hoping that people could help me go to the right direction by suggesting approaches. To start, I have found out that Avionics OEM software is often rehosted and retargeted by third parties e.g. simulator makers. I wonder how they test them. Surely, the source code will not be supplied due to IPR rgulations. UPDATE I have received reasonable and very useful suggestions regarding this area. My current struggle has shifted into testing 3rd party OBJECT code that needs to be linked with my own source code (retargeted) on my host machine. How can I even test object code? Surely, I need to link them first to even think about doing anything. Is it the post-link behaviour that needs to be determined and scripted (using perl,Tcl, etc.) so that inputs and outputs could be verified? No clue!! :( thanks,

• How are certain analytics metrics (time on site, etc.) usually distributed?

  - by a barking spider

  I'm not sure if I've come to the right place to ask this question, but I'm gathering some information for a research project. We're trying to design an experiment that'll heavily involve web analytics, and I'm trying to figure out some sensible values of mean +/- standard deviation for the following visitor-level (i.e., visitor 1 spends 2 minutes on site, visitor 2 spends 1 minute -- mean 1.5 +/- 0.71...) metrics: time spent on site page views If time allowed, we would put up the sites and gather the information ourselves, but we have a grant deadline coming up. I realize that even though these the distributions of these quantities are probably going to be heavily skewed towards zero, we'll need some reasonable figures or estimates of these figures in order to do sample size calculations, etc. Anyway, I'm not sure where else I'd turn, and I certainly have had a difficult time finding these values in the prior literature. If someone could direct me to a paper with the right information, or if you have these figures on hand (perhaps taken directly from your logs!) -- that would be amazing, and I'd love to hear from you. Thanks in advance, and even though I'm not allowed to reveal too much, rest assured that this info'll be applied towards a good cause :)

• Why don't my Fn keys work for brightness or media after upgrading?

  - by Adina G

  I recently upgraded from 11.04 to 11.10. After the upgrade, I can no longer adjust the screen brightness or the volume using keyboard (before the upgrade, using Fn+F4, Fn+F11, etc. worked). Using Fn+F2 to disable wireless still works, so I guess the Fn key itself is being recognised. I tried to follow the instructions here, but I don't have a file in /etc/X11 called xorg.conf. I also tried following this workaround, but it had no noticeable effect. I've also tried going to Settings ? Keyboard ? Shortcuts and reassigning the brightness and volume controls, both to the default keys and to new combinations. These changes don't have an effect even after rebooting. Googling has found bug reports where pressing the media keys brings up a "no entry sign" rather than changing the volume. When I press the keys there's no response at all. I've also seen various people say a workaround is to have totem running in the background; this doesn't work for me either. Finally, I tried installing keytouch; I was able to install keytouch-editor but got the message "Unable to locate package keytouch". Any more ideas? I'd be very grateful if anyone could help me (even by pointing to a thread I've missed)!

• Ubuntu for Phones / Touch vs Android, IOS and BlackBerry OS

  - by Ome Noes

  Currently I have a LG Google Nexus 4 with lots of issues because of the latest android 4.3 update. Since the update my battery drains within 7 hours when in it's standby / idle and even faster when I use it normaly! Before the Nexus 4 I had an Iphone but got sick of IOS because for me it's to much of a closed operating system and I dislike having to work with either Windows or Itunes. At this point neither Google or LG is willing to provide me (and all the others that have similar Nexus 4 problems) with a solution or even a reaction... Also i'm not very fond of the idea that the NSA (and maybe others) can and is currently monitoring millions of Android, IOS and BlackBerry OS devices all over the world. Since i've been using Ubuntu now very happily for almost 5 years I see Ubuntu for Phones / Touch as the only remedy for all this BS. Please be so kind to let me know when you will have a fully functioning version of your Ubuntu for Phones / Touch ready for consumer use. I'm realy sad that the Ubuntu Edge campaign didn't work out and hope to see lots and lots of future smartphones outfitted with Ubuntu a.s.a.p.! Keep up the good work!

• How do spambots work?

  - by rlb.usa

  I have a forum that's getting hit a lot by forum spambots, and of course the best way to defeat something is to know thy enemy. I'll worry about defeating those spambots later, but right now I'd like to know more about them. Reading around, I felt surprised about the lack of thorough information on the subject (or perhaps my ineptness to input the correct search terms for better google results). I'm interested in learning all about spambots. I've asked on other forums and gotten brush-off answers like "Spambots are always users registering on your site." How do forum spambots work? How do they find the 'new user registration' page? (I'm especially surprised because some forums don't have a dedicated URL for this eg, www.forum.com/register.html , but instead use query strings or even other methods invisible to the URL bar) How do they know what to enter into each 'new user registration' field? How do they determine what's a page they can spam / enter data into and what is not? Do they even 'view' this page at all? ..If not, then I'd assume they're communicating with the server directly - how is - this possible? How do they do it? Can forum spambots break CAPTCHAs? Can they solve logic questions (how?)? Math questions? Do they reverse-engineer client-side anti-bot validation scripts? Server-side scripts? What techniques are still valid to prevent them? Where do spambots come from? Is someone sitting behind the computer snickering as they watch their bot destroy site after site? Or are they snickering as they simply 'release' it onto the internet somehow? Are spambots 'run' by an infected computer somewhere? Do they replicate themselves? etc

• F# Application Entry Point

  - by MarkPearl

  Up to now I have been looking at F# for modular solutions, but have never considered writing an end to end application. Today I was wondering how one would even start to write an end to end application and realized that I didn’t even know where the entry point is for an F# application. After browsing MSDN a bit I got a basic example of a F# application with an entry point [<EntryPoint>] let main args = printfn "Arguments passed to function : %A" args // Return 0. This indicates success. 0 Pretty simple stuff… but what happens when you have a few modules in a program – so I created a F# project with two modules and a main module as illustrated in the image below… When I try to compile my program I get a build error… A function labeled with the 'EntryPointAttribute' attribute must be the last declaration in the last file in the compilation sequence, and can only be used when compiling to a .exe… What does this mean? After some more reading I discovered that the Program.fs needs to be the last file in the F# application – the order of the files in a F# solution are important. How do I move a source file up or down? I tried dragging the Program.fs file below ModuleB.fs but it wouldn’t allow me to. Then I thought to right click on a source file and got the following menu.   Wala… to move the source file to the bottom of the solution you can select the “Move Up” or “Move Down” option. Now that I got this right I decided to put some code in ModuleA & ModuleB and I have the start of a basic application structure. ModuleA Code namespace MyApp module ModuleA = let PrintModuleA = printf "hello a \n" ()   ModuleB Code namespace MyApp module ModuleB = let PrintModuleB = printf "hello b \n" ()   Program Code // Learn more about F# at http://fsharp.net #light namespace MyApp module Main = open System [<EntryPoint>] let main args = ModuleA.PrintModuleA let endofapp = Console.ReadKey() 0

• Ubuntu 11.10 won't let me login; it kicks me back to login screen

  - by zlyfire

  I was just copying files from my external HDD to my .wine directory, when I noticed the place where the launchers are (Unity desktop) was getting fuzzy and holding onto graphics from the things in the location prior(i have it autohide when a window covers it). I assumed it was just RAM problem, so I canceled the copying, since it wasn't actually important. The glitch remained, and so did another; very slow response time. The mouse moved just fine, but windows were waiting about a minute after I hit the x button to close or even switch active window. Once again, I blamed RAM (only have 2 GBs) so I restarted. Usually, it autologs me into my account, since I'm the only user, but this time it presented me with the login screen. I thought it odd, but tried to log in. A black screen with some text pops up (assuming terminal screen) for half a second then kicks me back to the login screen. I tried the guest account and no luck. I went into terminal (alt+ctrl+f1) and logged in and it worked. I deleted .Xauthority, made new account, and even rebooted quite a few times, all to no avail. Anyone have an idea?

• I just received a complaint from a user of the website I maintain. Should I do anything?

  - by Chris

  I was sent sent a large wall of text from a user of the website I maintain at my job. They are clearly upset for having to deal with a horribly outdated web application that has not seen any serious updates in over 6+ years. No refactoring has been done, the code quality is terrible, the security unchecked, policy compliances ignored, in addition to being ugly and frankly embarrassing. Keep in mind this is a small business but the website is used by hundreds daily. I'm one of two programmers there, and I've been working there for two years. This person says they are about my age (22) and understand technology (but can't use proper grammar). The complaint mentioned awkward pages and actions on the website, but they don't even have a clue as to the depth of the flaws in this website. Now, I would love to honestly tell them that there's a lot wrong with this company and that this application was built when we were in high school. And that while it's not my fault that the website is terrible, I'm the one in position to fix it. But on the other hand, I could just say nothing and ignore it. Would doing this publicly have any advantage to future employees (showing integrity) or would it just be a completely pointless mistake? Odds are, even if I respond only that one person will ever read it. Regardless, I'm probably just going to ignore it and continue starting my project to refactor the website.

• At what point does programming become a useful skill?

  - by Elip

  This is probably a very difficult question to answer, because of its subjectivity, but even a vague guess would help me out: Now that Khan Academy is beginning to offer Computer Science lectures I'm getting an itch to learn programming again. I maybe am a bit more technical than your average computer user, using Ubuntu as my OS, LaTeX for writing and I know some small tricks like regular expressions or boolean search for google. However from my previous attempts to learn programming, I realized I do not have a natural aptitude for it and I also don't seem to enjoy the process. But I am fairly certain that a basic proficiency in programming could prove to be very beneficial for me career wise; I also often get ideas for little scripts that I cannot implement. My question is: Let's say you study programming 1 hour / day on average. At what point will you become good enough so that programming can be used for automating tasks and actually saving time? Do you think programming is worth picking up if you never have the ambition to make it your career or even your hobby, but use it strictly for utility purposes?

• Crackling sound from microphone recently, in 13.04

  - by Patrig Droumaguet

  I use 13.04 since the release and I use Skype which was working well. But recently I've had remarks saying my voice was "crackling", even if the voice from my interlocutor was perfect. Making a test with Audacity and Cheese, I've seen that every recorded sound (with the front microphone of my laptop or a jack microphone) was crackling. It's not really like saturating, the sound has a lot of annoying pops. I've tried to check the settings, they were still on PulseAudio. I've even tried the extreme solution : re-installing Ubuntu (because initially it was working)… with the same problem. If I boot on Windows (dual-boot) I have no problem (so it's not physical). If anyone could help :) My laptop is a HP dv6-6165sf. The sound card is a "IDT 92HD81B1X5" (with BeatsAudio). Thanks a lot ! New tests - july 6th Hi again, I've tried editing /etc/pulse/default.pa with these three settings : load-module module-udev-detect use_ucm=0 tsched=0 load-module module-udev-detect tsched=0 load-module module-udev-detect use_ucm=0 The three of them don't change anything, except the last one (which was by default) which makes Audacity record without any crackling sound. But in Skype, Cheese and Kazam, the sound is crackling… I've installed again Ubuntu 13.04 (from scratch, deleting everything from /home), and I've updated it. The microphone is still cracking. Thanks for your help !

• How to get local business nationwide exposure? [closed]

  - by guisasso

  here's the situation: This company offers local home services (construction...), but also fabricates many custom items that can be shipped nationally, and even internationally. Since i started working on this website, it has ranked pretty well on alexa global and locally, and i have made many SEO improvements that doubled the visits to the website in 6 months. The website is listed in many different directories (dmoz & etc...), maps (google maps & etc...), business listing sites (yelp & etc..), trade specific websites (angie's list, houzz & etc...), state specific business listings and etc, there are many links to pictures displayed on the website, links to the website itself, i have a google analytics and webmaster tools account, with sitemaps, newsletters, facebook page.... the list goes on and on. All of which have been working pretty well locally. We have had some success with doing business in other states and even other countries, but it is still a pretty small percentage of the market. I also advertise on google adwords locally, and since this would be the obvious answer, my question is: Without paid advertisement, how can i improve the visibility of this local business website nationally to attract customers in all US States?

• Ubuntu 12.04 + Bluetooth problems with maintaining connection

  - by ifndefx

  I have an Apple Wireless Mouse, Apple Wireless Keyboard, Apple Wireless Trackpad, and a pair of headphones. All of these connect to the computer via a Bluetooth dongle. After several hours I've managed to get the devices paired (all except the headphones) with the computer. However, I'm facing a problem where a connection can't be maintained even with one device. I first started with the gnome bluetooth applet, this couldn't even pick up devices, so I installed blueman, and this at least detected the devices but it couldn't keep the connection going. Then i read somewhere to get hidd installed and use the command line using the mac address of the device (which I got from blueman) and this worked really well, the connection was stable, but there's still a couple of issues that I need help with: If I am to use hidd I need to execute this via terminal, which means for the keyboard and the mouse I need to have two of each. This doesn't make sense. I need the bluetooth daemon to have started with the devices picked up a lot earlier, and especially at grub bootloader. The mouse and the trackpad both work if i use hidd, however, I cannot get the right mouse to work nor the scroll wheel to work. The headphones don't work period, they don't work with any of the bluetooth applets, and with hidd either. When I use blueman aplet, it attempts to pair and states 'Authentication Rejected". The headphone is Phillips SHB9100. If someone can help me with this, I would be grateful.

• Where to find information about ubuntu compatible or certified hardware/PC models

  - by Halkinn

  I am buying a new desktop PC in early 2013, anyway this question should apply to someone intending to buy a new laptop/ultrabook as well. This machine is not meant for gaming, and if I ocasionally do it, I can survive with minimum graphics. However I may need some heavy multimedia edition or multitasking at times, so basically my greatest priority is a good processor, after that perhaps average graphic card (if onboards are not enough, I am still not informed enough about that), at least 4GB of RAM with possibility of expansion. I know there are some PC models specially designed to ship with Ubuntu, which is the OS I use the most these days. However, most people around me use Windows and some software with unsupported versions for Linux and not having a Windows license becomes a bit problematic. Given that, I would like to find information about which PC models or even manufacters currently on the market have the best compatibility with Ubuntu, I am still undecided between building my own desktop or buying a pre-made model, so I would like to find information both for certified models and certified hardware or even Ubuntu partners that may work closely with Canonical. Where to find this information in order to make sure that I will have a good experience with Ubuntu on my new PC in the years to come?

• Making a Living Developing Games

  - by cable729

  I'm in my last year of high school, and I've been looking at colleges. I'm taking a C++ class at a local community college and I don't feel that it's worth it. I could have learned everything in that class in a week. This had me thinking, would a CS degree even be worth it? How much can it teach me if I can learn everything on my own? Even if I do need to learn more advanced subjects, many colleges put their material online AND I can buy a book. Will companies hire me if I don't have a CS degree? If I have a portfolio will I stand a chance? What kind of things are needed in the portfolio? I want to live doing what I love - programming. So I will do it. I'm just not sure that a CS degree will do anything to me. In addition, if there is a benefit to getting a CS degree, what places are the best?

• WiFi problems on several Ubuntu installations

  - by Rickyfresh

  Okay this is the first time I have ever had to ask a question as usually the Ubuntu community have answered everything already but on this occasion there are many people asking for the answer but not one good solution has become available so far so someone please help or I will have to install Windows on my sons and my girlfriends PCs and that would be a disaster as I am trying to help convince people to move from Windows. I installed 12.04 on three computers on the same day. Dell Inspiron (Works Perfect) Toshiba Satellite Home built Desktop The Dell works perfect but the other two either keep losing connection to the wireless Internet and even when they are connected they stop connecting to web sites, for some reason it searches Google fine but will not connect to web sites when a link is clicked. So far people have recommended in other forums: Removing network manager and installing wicd (didn't solve it) Changing the MTU in the wireless settings (didn't solve it) All sorts of messing about with Firefox settings (this doesn't solve it and even if it did this would leave most average PC users scratching their heads and wishing they had stuck to windows) The problem exists on two very different machines and different wireless cards so I doubt its a driver or hardware issue, also many other Ubuntu users are having the same problem with a vast array of different machines and wireless cards. Can someone please give a good solution to this as its going to turn a lot of people away from Ubuntu if they cannot get this sorted. I would give some PC specs but the two machines are vastly different and the other people complaining of this problem also have very different systems all showing the same problem.

• Repository query conditions, dependencies and DRY

  - by vFragosop

  To keep it simple, let's suppose an application which has Accounts and Users. Each account may have any number of users. There's also 3 consumers of UserRepository: An admin interface which may list all users Public front-end which may list all users An account authenticated API which should only list it's own users Assuming UserRepository is something like this: class UsersRepository extends DatabaseAbstraction { private function query() { return $this->database()->select('users.*'); } public function getAll() { return $this->query()->exec(); } // IMPORTANT: // Tons of other methods for searching, filtering, // joining of other tables, ordering and such... } Keeping in mind the comment above, and the necessity to abstract user querying conditions, How should I handle querying of users filtering by account_id? I can picture three possible roads: 1. Should I create an AccountUsersRepository? class AccountUsersRepository extends UserRepository { public function __construct(Account $account) { $this->account = $account; } private function query() { return parent::query() ->where('account_id', '=', $this->account->id); } } This has the advantage of reducing the duplication of UsersRepository methods, but doesn't quite fit into anything I've read about DDD so far (I'm rookie by the way) 2. Should I put it as a method on AccountsRepository? class AccountsRepository extends DatabaseAbstraction { public function getAccountUsers(Account $account) { return $this->database() ->select('users.*') ->where('account_id', '=', $account->id) ->exec(); } } This requires the duplication of all UserRepository methods and may need another UserQuery layer, that implements those querying logic on chainable way. 3. Should I query UserRepository from within my account entity? class Account extends Entity { public function getUsers() { return UserRepository::findByAccountId($this->id); } } This feels more like an aggregate root for me, but introduces dependency of UserRepository on Account entity, which may violate a few principles. 4. Or am I missing the point completely? Maybe there's an even better solution? Footnotes: Besides permissions being a Service concern, in my understanding, they shouldn't implement SQL query but leave that to repositories since those may not even be SQL driven.

• What is the/Is there a right way to tell management that our code sucks?

  - by Azkar

  Our code is bad. It might not have always been considered bad, but it is bad and is only going downhill. I started fresh out of college less than a year ago, and many of the things in our code puzzle me beyond belief. At first I figured that as the new guy I should keep my mouth shut until I learned a little more about our code base, but I've seen plenty to know that it's bad. Some of the highlights: We still use frames (try getting something out of a querystring, almost impossible) VBScript Source Safe We 'use' .NET - by that I mean we have .net wrappers that call COM DLLs making it almost impossible to debug easily Everything is basically one giant function Code is not maintainable. Each page has multiple files that are created every time a new page is made. The main page basically does Response.Write() a bunch of times to render the HTML (runat="server"? no way). After that there can be a lot of logic on the client side (VBScript), and finally the page submits to itself (often time storing many things in hidden fields) where it then posts to a processing page which can do things such as save the data to the database. The specifications we get are laughable. Often times they call for things like "auto-populate field X with either field Y or field Z" with no indication of when to choose field Y or field Z. I'm sure some of this is a result of not being employed at a software company, but I feel as if people writing software should at least care about the quality of their code. I can't even imagine that if I were to bring something up that anything would be done soon, as there is a large deadline looming, but we are continuing to write bad code and use bad practices. What can I do? How do I even bring these issues up? 75% of my team agree with me and have brought up these issues in the past, yet nothing gets changed.

• How "commercially savvy" should software developers be? [closed]

  - by mattnz

  I have been watching answers to many questions on this site, and have come to the conclusion that commercial pragmatism does not factor into many software development discussions. As a result, I seriously wonder at the commercial skills within the industry, specifically the ability to deliver projects on time and to a budget. I see no indication from the site that commercially successful project delivery is a serious concern, yet the industry has a reputation for poor performance in this. Rarely, if ever, does the cost of time factor into discussions. I have never seen concepts such as opportunity cost, time to market, competitive advantage or cash flow mentioned, let alone discussed in technical answers to questions. How can you answer virtually any question without understanding the commercial background on which it is asked? Even Open source projects have a need to operate efficiently and deploy their limited resources to providing the most value for effort. Typically small start-ups have cash flow issues that outweigh longevity concerns, yet they are typically still advised to build for a future they probably won’t have if they do. Is it fair to say that these problems are solely the Managers and Project managers to solve, or are we, as developers, also responsible for ensuring successful on time, within budget delivery of projects, even if those budgets do not allow use to achieve engineering excellence?
