  • Offshoring: does it ever work?

    - by DanSingerman
    I know there has been a fair amount of discussion on here about outsourcing/offshoring, and the general opinion seems to be that at best it is difficult, and at worst it fails. I have direct experience of offshoring myself; a previous company where I was a dev manager wanted to send some development offshore, and we ran a pilot scheme to see how well it would work. Of course it was a complete failure, although it is not completely clear to me whether this was down to the offshore devs being less talented, the process, or other factors (no doubt it was really a combination). I can see as a business how offshoring looks attractive (much lower day rate), but as far as I can see, the only way it could possibly work is if you do exceptionally detailed design up front, with incredibly detailed specifications; and by the time you have invested in producing that, you have probably spent as nearly as much as if you had written the actual code locally (which I think is an instance of No Silver Bullet) So, what I want to know is, does anyone here have any experience of offshoring actually working ever? Especially if there are any success stories of it working in a semi-agile way? I know there are developers here from all over the World; has anyone worked on an offshore project they consider successful?

  • Sound not working after installing PCI video card and then removing it

    - by bakhshu
    I am running 11.10 on a HP/Compaq Presario sr1010z, and the video/audio was working fine with whatever was in the machine already. Then I installed a new video card (PCI/nVidia), which disabled the audio/video on the old one automatically. But that card didn't work out too well so I removed it. Now the video is back to normal, but the audio is gone. I have tried the following: 1. In BIOS, set audio to on/enable rather than Auto 2. Looked for hardware in System Settings Sound, but nothing shows up there 3. But when I run the sysinfo utility, I get the description of the audio controller When I do a 'sudo aplay -l', I get 'aplay: device_list:240: no soundcards found...' And then when I do a 'lspci -v | grep -A7 -i "audio"' I get the following: 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] SiS7012 AC'97 Sound Controller (rev a0) Subsystem: Hewlett-Packard Company Device 2a05 Flags: bus master, medium devsel, latency 32, IRQ 5 I/O ports at a000 [size=256] I/O ports at a400 [size=128] Capabilities: 00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.1 Controller (rev 0f) (prog-if 10 [OHCI]) Any ideas on how to fix this?

  • Installing BURG (NO MBR!)

    - by StepTNT
    I'd like to install BURG but I don't want it to overwrite my MBR. That's because I've got two bootloader in my system : 1) Default Windows 7 bl in my MBR 2) Grub in /dev/sda2 With the first power button, it will boot as Grub is not installed, so it simply loads Windows, with the second button it boots from /dev/sda2, loading Grub and then Kubuntu. Now I want to replae Grub with Burg. I've installe Burg with burg-install /dev/sda2 --force because I don't want my MBR to be overwritten (pressing the first power button MUST load Windows and avoid showing any sign of Linux things). Setup was completed without errors, and everything seems to work fine : if I open burg-manager it loads my settings, allowing me to change them and to test everything with burg-emu (that works as I want to). So, everything seems fine, Burg's installed, I've changed my settings but.. If I use the second power button, it still loads Grub! (Even a different version from the default Kubuntu one). So, here's the question : How can I replace GRUB that's on /dev/sda2 with BURG and WITHOUT writing it to my MBR? Thanks :)

  • How to capture a Header or Trailer Count Value in a Flat File and Assign to a Variable

    - by Compudicted
    Recently I had several questions concerning how to process files that carry a header and trailer in them. Typically those files are a product of data extract from non Microsoft products e.g. Oracle database encompassing various tables data where every row starts with an identifier. For example such a file data record could look like: HDR,INTF_01,OUT,TEST,3/9/2011 11:23 B1,121156789,DATA TEST DATA,2011-03-09 10:00:00,Y,TEST 18 10:00:44,2011-07-18 10:00:44,Y B2,TEST DATA,2011-03-18 10:00:44,Y B3,LEG 1 TEST DATA,TRAN TEST,N B4,LEG 2 TEST DATA,TRAN TEST,Y FTR,4,TEST END,3/9/2011 11:27 A developer is normally able to break the records using a Conditional Split Transformation component by employing an expression similar to Output1 -- SUBSTRING(Output1,1,2) == "B1" and so on, but often a verification is required after this step to check if the number of data records read corresponds to the number specified in the trailer record of the file. This portion sometimes stumbles some people so I decided to share what I came up with. As an aside, I want to mention that the approach I use is slightly more portable than some others I saw because I use a separate DFT that can be copied and pasted into a new SSIS package designer surface or re-used within the same package again and it can survive several trailer/footer records (!). See how a ready DFT can look: The first step is to create a Flat File Connection Manager and make sure you get the row split into columns like this: After you are done with the Flat File connection, move onto adding an aggregate which is in use to simply assign a value to a variable (here the aggregate is used to handle the possibility of multiple footers/headers): The next step is adding a Script Transformation as destination that requires very little coding. First, some variable setup: and finally the code: As you can see it is important to place your code into the appropriate routine in the script, otherwise the end result may not be as expected. As the last step you would use the regular Script Component to compare the variable value obtained from the DFT above to a package variable value obtained say via a Row Count component to determine if the file being processed has the right number of rows.

  • Cryptswap boot error - can't mount?

  • How does one find out which application is associated with an indicator icon in Ubuntu 12.04?

    - by Amos Annoy
    It is trivial to do this in Ubuntu 10.04. The question is specific to Ubuntu 12.04. This has nothing to do (does it?) with right click. How can an indicator's icon in Ubuntu 12.04 be matched with the program responsible for it's manifestation on the top panel? A list of running applications can include all processes using System Monitor. How is the correct matching process found for an indicator? (the examination of SM points out a rather poignant factor in the faster depletion and shortened run time on battery - the ambient quiescent CPU rate in 12.04 is now well over 20% when previously it was well under 10% in 10.04, between 5% and 7%!) (I have a problem with the battery indicator - it sometimes has % and other times hh:mm - it is necessary to know the ap. & v. to get more info on controlling same. ditto: There are issues with other indicator aps.) Details from: How can I find Application Indicator ID's? suggests looking at: file:///usr/share/indicator-application/ordering-override.keyfile [Ordering Index Overrides] nm-applet=1 gnome-power-manager=2 ibus=3 gst-keyboard-xkb=4 gsd-keyboard-xkb=5 which solves the battery identification, and presumably nm is NetworkManager for the rf icon, but the envelope, blue tooth and speaker indicator aps. are still a mystery. (Also, the ordering is not correlated.) Mind you, it was simple in the past to simply right click to get the About option to find the ap. & v. info. browsing around and about: file:///usr/share/indicator-application/ordering-override.keyfile examined: file:///usr/share/indicators file:///usr/share/indicators/messages/applications/ ... perhaps?/presumably? the information sought may be buried in file:///usr/share/indicators

  • Could not load file or assembly 'System.Data.SQLite' or one of its dependencies. An attempt was made to load a program with an incorrect format.

    - by Om Talsania
    Problem Description: Could not load file or assembly 'System.Data.SQLite' or one of its dependencies. An attempt was made to load a program with an incorrect format. Likely to be reproduced when: You will usually encounter this problem when you have downloaded a sample application that is a 32-bit application targeted for ASP.NET 2.0 or 3.5, and you have IIS7 on a 64-bit OS running .NET 4.0, because the default setting for running 32-bit application on IIS7 with 64-bit OS is false. Resolution: 1. Go to IIS Management Console Start -> Administration Tools -> Internet Information Services (IIS) Manager 2. Expand your server in the left pane and go to Application Pools 3. Right click to select ‘Add Application Pool’  4. Create anew AppPool. I have named it ASP.NET v2.0 AppPool (32-bit) and selected .NET Framework v2.0.50727 because I intend to run my ASP.NET 3.5 application on it. 5. Now right click the newly created AppPool and select Advanced Settings 6. Change the property “Enable 32-Bit Applications” from False to True  7. Now select your actual web application from the left panel. Right click the web application, and go to Manage Application -> Advanced Settings  8. Change the Property “Application Pool” to your newly created AppPool.  And… the error is gone…

  • What is the target of Unity?

    - by burli
    First Unity was developed for Netbooks. But the Netbook Market is shrinking. Unity is not specialized for tablet pcs like Android 3, but it may work well with some specialized Apps for those devices. Unity is still nice for Notebooks with small displays, but there is no big advantage on the desktop compared with other desktop environments like Gnome 2/3 or KDE. So what's the point? My first suggenstion was a hybrid between tablet pc and a desktop, for example for a manager. He can plug the tablet in a docking station in his office and he can work at a normal desktop, whats not possible with iOS or Android. If he is in a meeting he can use it as a tablet to make notes, for example. Or if he is somewhere else outside the office or the company. Same for normal users. They can dock the tablet and use it like a normal desktop pc or they can lie on the couch and browse in the web, read a book or chat with friend. So, thats my suggestion. But what is the real plan for Unity or Ubuntu in general? I'm curious ;)

  • How to configure ubuntu ldap client to get password policies from server?

  • Terminal/Putty showing control characters (^M) after updating

    - by jaycee48
    I updated my system yesterday afternoon using the recommended updates from Update Manager. After it completed, I shutdown my system and went home for the day. I come in this morning and I am getting control characters displayed when using vi in both the standard terminal emulator, putty, and putty inside of my Windows virtual that I run with VirtualBox. I have made no other system changes and I cannot figure out how this occurred. It's as if every text file I have was created in DOS. I've searched the forums and I haven't found any answers. I am using xterm as my emulator and I checked with 3 of my coworkers and none of them are having this problem so we do not believe it is a server side issue. Especially since I've checked 3 different servers. There's nothing in my .profile other than PATH variables so I'm using the same terminal settings as everyone else. Some files are fine (I can open and read both /etc/environment and my .profile) but most of any kind of server generated log file is trash. Running cat or head on the same file displays the contents without the characters. Any ideas would be appreciated. Thanks.

  • Pandaboard crash on startup or freeze after minutes

    - by Meach
    I just received my Pandaboard ES (rev B) and I am having trouble after installing ubuntu-omap4-addons. Once I copied the image ubuntu-12.04-preinstalled-desktop-armhf+omap4.img on my sd card and boot the pandaboard with it, I run the following commands: sudo add-apt-repository ppa:tiomap-dev/release sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ubuntu-omap4-extras At the end of the installation of ubuntu-omap4-extras, Ubuntu tells me that a problem occurs when the console displays: ldconfig deferred processing now taking place Clicking on "report the problem" tell me that the problem concerns pvr-omap4-dkms. I read somewhere that this can happen and it is better to reinstall pvr-omap4-dkms. Which I am doing by running: sudo apt-get install --reinstall pvr-omap4-dkms I reboot. Then the board has sometimes difficulties to start Ubuntu: it freezes during the loading page, only action I can do is unplugging the board to start it again. Some other times, Ubuntu load successfully but then freeze at another random time, in the range 20 - 40 minutes. I searched on internet for similar bug and found this: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/971091 So I typed this in: update-rc.d ondemand disable apt-get -y install cpufrequtils echo 'ENABLE="true" GOVERNOR="performance" MAX_SPEED="0" MIN_SPEED="0"' > /etc/default/cpufrequtils cpufreq-set -r -g performance reboot But it doesn't seems to fix the bug. Another detail: on startup, before the loading screen of Ubuntu (when there is the two penguins displayed :)), it shows this: [0.297271] CPU1: Unknown IPI message 0x1 [0.308990] omap_hwmod: mcpdm: _wait_target_ready error: -16 [0.354705] omap_mux_get_by_name: Could not find signal uart1_cts.uart1_cts [0.354766] omap_hwmod_mux_init: Could not allocate device mux entry [2.107086] thermal_get_slope:Getting slope is not supported for domain gpu [2.107116] thermal_get_offset:Getting offset is not supported for domain gpu [2.107299] stm_fw: vendor driver stm_ti1.0 registered [8.725555] OMAPRPC: Registration of OMAPRPC rpmsg service returned 0! debug=0 Any idea what can be wrong?

    Disclaimer: probably going to next years TechEd.  (but not 100% sure) As with most TechEd's, this is not one of the best - but it's not bad.  Some impressions so far: The food is not bad, through perhaps not as much choice as in previous years.  The snacks, while a bit limited, are at least available.  The alumni lounge is ok, through perhaps not as good as last years.  Wifi is a bit worse than previous years - not really working in the big room, and a bit sporadic in the rest of the building. The device seems to make a big difference - the iPad seems to connect the easiest, while the iPhone & Lumia 800 are really struggling.  The real problem is the content - not as developer focused as in previous years.  This shows up in a number of different ways, for example while there is a visual studio booth, there is not much sign of anybody from the language teams.  This is one of few TechEd's where I don't feel very surprised about anything - seen most of the developer stuff in previews. One example where I was surprised was the pre-conf on c++ - its been years since I did any c++, but based on that session perhaps I should start again. While there are sessions, I'm not finding my schedule very challenged. For each time-slot there only seems to 1, or rarely 2, interesting sessions.  The focus seems to be on windows 8, Azure and the phone, which while interesting (might give win8 a go), are not enough.

  • How important is Domain knowledge vs. Technical knowledge?

    - by Mayank
    I am working on a Trading and Risk Management application and although from a C# background, I have been asked to work on SSIS packages. Now I can live with that. The pain point is that there is too much emphasis on business understanding. Trading (Energy Trading to be exact) is a HUGE area and understanding every little bit of it is overwhelming. But for the past two months I have been working on understanding the business terms - Mark To Market, Risk Metrics, Positions, PnL, Greeks, Instruments, Book Structure... every little detail (you get the point). Now IMHO, this is the job of a BA. Sure it is very important for developers to understand the business but where do you draw the line? When I talked to my manager about this, he almost mocked me by saying that anybody can learn a technology in a week. It's the business that's harder. My long term aspiration is to remain on the technical side, probably become an architect (if possible). If I wanted to focus so much on business I would have pursued an MBA! I want to know if I am wrong or too naive in understanding the business importance or is my frustration justified?

  • Navigation in Win8 Metro Style applications

    - by Dennis Vroegop
    In Windows 8, Touch is, as they say, a first class citizen. Now, to be honest: they also said that in Windows 7. However in Win8 this is actually true. Applications are meant to be used by touch. Yes, you can still use mouse, keyboard and pen and your apps should take that into account but touch is where you should focus on initially. Will all users have touch enabled devices? No, not in the first place. I don’t think touchscreens will be on every device sold next year. But in 5 years? Who knows? Don’t forget: if your app is successful it will be around for a long time and by that time touchscreens will be everywhere. Another reason to embrace touch is that it’s easier to develop a touch-oriented app and then to make sure that keyboard, nouse and pen work as doing it the other way around. Porting a mouse-based application to a touch based application almost never works. The reverse gives you much more chances for success. That being said, there are some things that you need to think about. Most people have more than one finger, while most users only use one mouse at the time. Still, most touch-developers translate their mouse-knowledge to the touch and think they did a good job. Martin Tirion from Microsoft said that since Touch is a new language people face the same challenges they do when learning a new real spoken language. The first thing people try when learning a new language is simply replace the words in their native language to the newly learned words. At first they don’t care about grammar. To a native speaker of that other language this sounds all wrong but they still will be able to understand what the intention was. If you don’t believe me: try Google translate to translate something for you from your language to another and then back and see what happens. The same thing happens with Touch. Most developers translate a mouse-click into a tap-event and think they’re done. Well matey, you’re not done. Not by far. There are things you can do with a mouse that you cannot do with touch. Think hover. A mouse has the ability to ‘slide’ over UI elements. Touch doesn’t (I know: with Pen you can do this but I’m talking about actual fingers here). A touch is either there or it isn’t. And right-click? Forget about it. A click is a click.  Yes, you have more than one finger but the machine doesn’t know which finger you use… The other way around is also true. Like I said: most users only have one mouse but they are likely to have more than one finger. So how do we take that into account? Thinking about this is really worth the time: you might come up with some surprisingly good ideas! Still: don’t forget that not every user has touch-enabled hardware so make sure your app is useable for both groups. Keep this in mind: we’re going to need it later on! Now. Apps should be easy to use. You don’t want your user to read through pages and pages of documentation before they can use the app. Imagine that spotter next to an airfield suddenly seeing a prototype of a Concorde 2 landing on the nearby runway. He probably wants to enter that information in our app NOW and not after he’s taken a 3 day course. Even if he still has to download the app, install it for the first time and then run it he should be on his way immediately. At least, fast enough to note down the details of that unique, rare and possibly exciting sighting he just did. So.. How do we do this? Well, I am not talking about games here. Games are in a league of their own. They fall outside the scope of the apps I am describing. But all the others can roughly be characterized as being one of two flavors: the navigation is either flat or hierarchical. That’s it. And if it’s hierarchical it’s no more than three levels deep. Not more. Your users will get lost otherwise and we don’t want that. Flat is simple. Just imagine we have one screen that is as high as our physical screen is and as wide as you need it to be. Don’t worry if it doesn’t fit on the screen: people can scroll to the right and left. Don’t combine up/down and left/right scrolling: it’s confusing. Next to that, since most users will hold their device in landscape mode it’s very natural to scroll horizontal. So let’s use that when we have a flat model. The same applies to the hierarchical model. Try to have at most three levels. If you need more space, find a way to group the items in such a way that you can fit it in three, very wide lanes. At the highest level we have the so called hub level. This is the entry point of the app and as such it should give the user an immediate feeling of what the app is all about. If your app has categories if items then you might show these categories here. And while you’re at it: also show 2 or 3 of the items itself here to give the user a taste of what lies beneath. If the user selects a category you go to the section part. Here you show several sections (again, go as wide as you need) with again some detail examples. After that: the details layer shows each item. By giving some samples of the underlaying layer you achieve several things: you make the layer attractive by showing several different things, you show some highlights so the user sees actual content and you provide a shortcut to the layers underneath. The image below is borrowed from the http://design.windows.com website which has tons and tons of examples: For our app we’ll use this layout. So what will we show? Well, let’s see what sorts of features our app has to offer. I’ll repeat them here: Note planes Add pictures of that plane Notify friends of new spots Share new spots on social media Write down arrival times Write down departure times Write down the runway they take I am sure you can think of some more items but for now we'll use these. In the hub we’ll show something that represents “Spots”, “Friends”, “Social”. Apparently we have an inner list of spotter-friends that are in the app, while we also have to whole world in social. In the layer below we show something else, depending on what the user choose. When they choose “Spots” we’ll display the last spots, last spots by our friends (so we can actually jump from this category to the one next to it) and so on. When they choose a “spot” (or press the + icon in the App bar, which I’ll talk about next time) they go to the lowest and final level that shows details about that spot, including a picture, date and time and the notes belonging to that entry. You’d be amazed at how easy it is to organize your app this way. If you don’t have enough room in these three layers you probably could easily get away with grouping items. Take a look at our hub: we have three completely different things in one place. If you still can’t fit it all in in a logical and consistent way, chances are you are trying to do too much in this app. Go back to your mission statement, determine if it is specific enough and if your feature list helps that statement or makes it unclear. Go ahead. Give it a go! Next time we’ll talk about the look and feel, the charms and the app-bar….

  • Internet Timeouts with TP-Link TL-WN821N v2 wireless usb stick

    - by user1622959
    A short time after accessing the internet, the browser/download times out. Before the timeout, the internet works OK briefly; afterwards, the wireless is still connected with a strong signal, but every internet access results in a timeout. When I leave the PC for a while, the internet is back just to timeout again as soon as I start using it. The same happens when I reconnect to the router. Also, when I surf the internet, it takes a couple of minutes until the timeout, but when I download something, it times out in a matter of seconds. The wireless adapter works just fine in Windows and internet via ethernet cable works just fine in Ubuntu. Does anyone have the same problem or knows a solution. I use Ubuntu 12.10 x64. The problem occurs since I installed ubuntu (which was a few days ago). Here some stuff that might be usefull: serus@serus-Ubuntu-PC:~$ lsusb Bus 002 Device 002: ID 0cf3:1002 Atheros Communications, Inc.

  • Easter eggs as IP protection in software

    - by Simon
    I work in embedded software, and for some reason, management wants to hide an Easter egg as means of IP protection. They call it a watermark, and since our software interact with the video preview feed (the image displayed on a screen before you take a photo), they want me to implement a trigger which will react to some unusual video input (a video konami code like dark - bright - dark - bright - whatever). When this trigger fires, something strange happens (which is outside of the normal behavior of the software). The goal is to check whether our software is included in a device. Does it sound like a good idea? I have many argument against this move: What if the konami code is too sensitive and user triggers it? Does this kind of watermark have any legal value? What if this "feature" is discovered by the client? The performance penalty should be very small, since the soft run on small devices. I am the one developping this trigger. If things go wrong, what is my responsibility? What is your opinion about this method? I can't find a link, but I remember seeing an answer on this site suggesting that putting Easter eggs for protection purpose was a good idea. Has anyone tried it with good results?

  • Dependencies not met on 12.04?

    - by Mochan
    Now I'm very aware that there are many questions out there that are quite similar to what I'm experiencing, but I have looked through many and I have not found a suitable answer. You are welcome to suggest questions that are similar, but I doubt that it will help. Getting on to the issue at hand, whenever I do anything that involves installation, whether it be codecs for videos, new programs or whatever the latter, I always get the 'Dependencies not met' error. In addition, I also get this notification in the panel: When clicked, the menu says this: "An error occurred. Please run Package Manager from the right-click menu or run apt-get in a terminal to see what is wrong. The error message was: ' Error: Broken Count 0'. This usually means your installed packages have unmet dependencies." It gives me three items to click: Show Updates Install all updates Check for Updates And then finally: Show Notifications (with a tick) Preferences When I try 'Install all Updates' (also Check Updates Install) it says this: and also this: As well as 'Ubuntu has experienced an internal error' and 'Did this error occur when moving from one version of Ubuntu to another?' (I clicked NO, because it didn't). So I took it's advice and ran sudo apt-get install -f This is what results: Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following extra packages will be installed: libapt-pkg4.12:i386 The following packages will be upgraded: libapt-pkg4.12:i386 1 upgraded, 0 newly installed, 0 to remove and 87 not upgraded. 1 not fully installed or removed. Need to get 0 B/941 kB of archives. After this operation, 0 B of additional disk space will be used. Do you want to continue [Y/n]? Y E: Internal Error, No file name for libapt-pkg4.12 When running sudo apt-get update it's all fine, but running sudo apt-get install -f still results in the same thing. I really have no idea what to do... can anyone help me?

  • how to make a continuous machine gun sound-effect

    - by Jan
    I am trying to make an entity fire one or more machine-guns. For each gun I store the time between shots (1.0 / firing rate) and the time since the last shot. Also I've loaded ~10 different gun-shot sound-effects. Now, for each gun I do the following: function update(deltatime): timeSinceLastShot += deltatime if timeSinceLastShot >= timeBetweenShots + verySmallRandomValue(): timeSinceLastShot -= timeBetweenShots if gunIsFiring: displayMuzzleFlash() spawnBullet() selectRandomSound().play() But now I often get a crackling noise (which I assume is when two or more guns are firing at the same time and confuse the sound-device). My question is whether A) This a common problem and there is a well-known solution, maybe to do with the channels or something, or B) I am using a completely wrong approach to the task. I had a look at some sound-assets for other games and they used complete burst with multiple shots. I suppose I could try that, but I would like to have organic little hickups in the gun-fire (that's what the random value is for) to make the game more gritty and dirty. I am using Panda3D, but I had the exact same problem in PyGame and SDL. [edit] Thanks a lot for the answers so far! One more problem with faking it though: Now how do I stop the sound? Let's say I have an effect with 5 bangs... *bang* *bang* *bang* *bang* *bang* And I magically manage to loop it so that there's no gap or overlap if the player fires more than 5 shots. Now, what do I do if the player stops firing halfway through the third bang? How do I know how long to keep playing the sample so that the third bang is completed and I can start playing the rumbling echo of the last shot? Of course I can look up the shot/pause timing of that sound-sample and code accordingly, but it feels extremely hacky.
