  • Dom U Installation on Ubuntu 11.10

    - by sridutt
    I am trying to add a DomU Operating system on Ubuntu 11.10. I have successfully installed Xen. Verified with xm info virsh-version which returns: Compiled against library: libvir 0.9.2 Using library: libvir 0.9.2 Using API: Xen 3.0.1 Running hypervisor: Xen 4.1. Now when I tried to install Dom0 it said: unable to connect to 'localhost:8000': , in VMM. So, I followed this bug link. I could now start adding DomU. When adding DomU, in last stage, it gives the following error: Unable to complete install: 'POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: device model '/usr/lib/xen/bin/qemu-dm' not found")' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 44, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 1899, in do_install guest.start_install(False, meter=meter) File "/usr/lib/pymodules/python2.7/virtinst/Guest.py", line 1223, in start_install noboot) File "/usr/lib/pymodules/python2.7/virtinst/Guest.py", line 1291, in _create_guest dom = self.conn.createLinux(start_xml or final_xml, 0) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 1686, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: device model '/usr/lib/xen/bin/qemu-dm' not found") I tried following this bug link that said, the bug is solved in the below package.

  • Is there a typical career path to learn game development "on the job"?

    - by mac
    The extended version of the question is: what is the typical career paths that a developer without specific experience in game development should take if he/she wishes to work in the game development industry? In other words, what are the positions such a programmer might aspire to get hired for, in the game industry? I am asking because it seems to me that - even without direct experience with 3D modelling, physics engines, shaders, etc... - for as much complex as these topics might be - they are still "just" top layers one can learn "on the job" if he/she has already good programming skills and experience in software design (for example during peer-programming sessions). I have no knowledge whatsoever of the game industry, so maybe I am being naïve here, but for all the other programming jobs I previously took, I learnt most of the specificities while working on concrete projects... so I wonder if there is a chance to do the same with game development. Thanks for your time and advice! :) PS: I don't know if this is important or not for answering the question, but scripting languages are the languages I am more proficient in. /mac

  • Kindle App for WP7 arrives

    - by dotgeek
    If you had asked me if I was interested in owning a Kindle device, then my response a couple months back would have been a flat out no back then. So what has changed between now on then you might be asking me then? I would have to say watching my wife enjoy the many books in digital form has peeked my interest to start with now. Was that enough for me to buy a Kindle though? Not just yet, but that is where the Windows Phone 7 comes in for me once again. It’s no secret that I’ve wanted this device and yes it does have a number of Apps that I think I’ll really enjoy. The latest must have App for me, will most certainly be the Kindle App for Windows Phone 7, released from Amazon today. I’ve already started playing around with the PC version of Kindle software and I’m looking at purchasing any future books in digital form now. So it’s a given once I have a Windows Phone 7 device, that I’ll be enjoying some of my favorite books, while I’m on the go I think and via this App. Tonight I actually had a chance to check out the WP7 Kindle App on a friends device and I was really pleased with how it looked and performed. Now if the planets could only manage to lineup for me and allow Verizon and Microsoft to come to terms on the releasing of WP7 CDMA devices, I just might be able to really enjoy some of this on my own. Do I rule out ever having an actual Kindle device? Not at all, but I do plan on having the WP7 device well before that day ever comes though.

  • 1080p Screen resolution problem after 10.04 to 12.04 update

    - by Ale
    I have a Samsung LCD 40" with a NVidia GeForce 6150SE nForce 430 Card. I recently upgraded from 10.04 to 12.04 and the best resolution I can get is 1360x768. I've tried the propietary drivers available on the repository kmod:nvidia_current kmod:nvidia_173_updates kmod:nvidia_current_updates kmod:nvidia_96 kmod:nvidia_96_updates kmod:nvidia_173 I've also downloaded latest from NVidia's Web, version: 295.40. But still no luck. With Nouveau driver, I can only get 1024x768. I know there is no problem with my hardware (video card, cable and monitor), I was using it perfectly on 10.04. Can anybody suggest something else I could try, to get my 1920x1080 resolution back? Thanks in advance. Here are some more information, that I got reading other similar posts on askubuntu. $ lspci | grep VGA 00:0d.0 VGA compatible controller: NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2) $ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1360 x 768, maximum 1360 x 768 default connected 1360x768 0 0 0mm x 0mm 1360x768 50.0 52.0* 1024x768 51.0 800x600 53.0 54.0 55.0 680x384 56.0 57.0 640x480 58.0 576x432 59.0 512x384 60.0 400x300 61.0 62.0 63.0 320x240 64.0

  • How to suggest changes as a recently-hired employee ?

    - by ereOn
    Hi, I was recently hired in a big company (thousands of people, to give an idea of the size). They said they hired me because of my rigor and because I was, despite my youngness (i'm 25), experienced as a C/C++ programer. Now that I'm in, I can see that the whole system is old and often uses obsolete technologies. There is no naming convention (files, functions, variables, ...), they don't use Version Control, don't use exceptions or polymorphism and it seems like almost everybody lost his passion (some of them are only 30 years old). I'd like to suggest somes changes but i don't want to be "the new guy that wants to change everything just because he doesn't want to fit in". I tried to "fit in", but actually, It takes me one week to do what I would do in one afternoon, just because of the poor tools we're forced to use. A lot my collegues never look at the new "things" and techniques that people use nowadays. It's like they just given up. The situation is really frustrating. Have you ever been in a similar situation and, if so, what advices would you give me ? Is there a subtle way of changing things without becoming the black sheep here ? Or should I just give up my passion and energy as well ? Thank you. Updates Just in case (if anyone cares): following your precious advices I was able to suggest changes and am now in charge of the team that must create and deploy Subversion :D Thanks to all of you !

  • Developing an iOS app for a single device - licensing issue

    - by bfavaretto
    I'm developing an iOS app for a museum as a freelancer. It's a very simple video player, to be installed on a single iPad that will be part of a permanent exhibition, basically acting as a kiosk. It turns out the iPad is the ideal device for that if you're looking for a small and affordable touchscreen. The problem is: as far as I can tell, none of the Apple Developer Program options available will allow me to distribute an app like that. The relevant options are (from the link above): iOS Developer Program ($99/year) Select this program if you would like to distribute apps on the App Store as an individual, sole proprietor, company, organization, government entity or educational institution. iOS Developer Enterprise Program ($299/year) Select this program if you would like to develop proprietary apps for internal distribution within your company, organization, government entity or educational institution. The regular program requires distribution through the App Store. The Enterprise version is for internal distribution within my own organization. Neither is the case here! It seems like I'm doomed to violate Apple's terms of service (and I can think of at least two ways of doing that: jailbreaking, or changing the iPad's date so it won't know the provisioning profile expired). Is that really so, or did I get the descriptions wrong? Has anyone here been in a similar situation?

  • Game crash/Screen freeze recovery (without shell or reboot)

    - by Asavar Tzeth
    I am an old Windows PC gamer, now converted into Ubuntu (Linux) lover. I am even going so far as to attempt to replace all my games in a Windows dual-boot with Wine and it is going well. However... Even if Linux is less prone to crashing, games, especially the windows ones (but also a few native) can crash. My problem is when this is in full screen and the computer becomes non-responsive. In Windows you can solve this with ctrl+alt+delete, but Ubuntu lacks this feature and my only choice is a reboot. Is there any Ubuntu version of this feature? Of course excepting the ctrl+alt+F1, find and kill process method. It is fine if you know how to do it, but too slow and difficult for the typical gamer. I believe strongly in Ubuntu as the future gaming platform in one form or another. If this feature does not exist, then the Ubuntu team should address this as fast as possible, since it is critical for all old Windows gamers. Thank you for your time. Asavar Tzeth (Alias)

  • Upgrading to 12.10 on an external hard drive

    - by Tom Childers
    I did some googling on this and didn't find anything specific for my situation. I currently have 12.04 installed on an external USB hard drive. It's working great. I want to upgrade it to 12.10. My bandwidth is very limited so I have a friend who will download 12.10 for me and put it on a flash stik. Then I can upgrade without having to do the download myself. Which particular version of the 12.10 download file(s) should I get? Are there alternate 12.10 downloads that have all the packages? How do I set it up so when I upgrade 12.04 I can specify that it look in some local repository for the 12.10 files? Can I just dump the 12.10 files in some local directory? Or do I have do go thru some complex commands to create a local repository? I'm pretty new to Linux so a long process of complex terminal commands will probably be a show stopper for me. Remember that my 12.04 install resides on an external hard drive. And I have a laptop with multiple USB ports. Thanks! Advait

  • Fresh install of 64 bit 12.04 over 32 bit 11.10 alongside Windows 7

    - by Pareen
    I currently have Ubuntu 11.10 32 bit and Windows 7 dual boot in separate partitions. I am trying to do a fresh install of Ubuntu 12.04 64 bit (mistakenly installed the 32 bit 11.10 a little while ago.. I need a 64 bit version to support AOSP build) OVER my the exisiting 11.10 partition. I have referenced How to Install fresh 12.04 install to a PC with dual booting Windows 7 & Ubuntu11.10?, as well as other posts on using the Live CD to do a fresh install. However, the problem I am experiencing is when I bring up the install screen, it says the following: This computer has multiple operating systems on it. What would you like to do. (3 options) Install Ubuntu 12.04 alongside them Replace all with Ubuntu 12.04 (Warning, this will delete files across ALL operating systems) Something else (you can create or resize partitions yourself) This is different from what is in other posts, as mine states that there are "multiple O.Ses" and doesnt individually allow me to replace the Ubuntu 11.10. I don't want to replace ALL O.S.es: I need to preserve Windows 7 and am only trying to replace the old Ubuntu 11.10 partition with the new 12.04 64 bit. I did have Ubuntu installed via Wubi (I believe it was 10.04) prior to putting 11.10 in a separate partition, but I have removed it via Add/Remove programs in Windows. I was wondering how to go about doing this... Should I use the "Something else" option to bring up the partition manager, and just assign my existing 11.10 partition with root mount point + swap space. Will this do the same thing by overwriting with fresh 12.04 install?? I appreciate all your help.

  • Need help: jBPM installation issue

    - by Kouky
    This is Ms Kahina, I’m getting started with jBPM & Java EE, I tried to install the jBPM 5.4 version by following all the steps stated in the iBPM user guide as below: 1- I’ve installed Java (JDK 1.7) and ant ( Apache-ant-1.9.4). 2- I’ve set both JAVA_HOME and ANT_HOME environement variables. 3- I’ve downloaded the jBPM 5.4 full installer and run the installation script “ant install.demo” and after that the start script “ant start.demo”. But unfortunately jBPM 5.4 is not working. When running the installation Script I’m getting successful message but with the following warnings : [copy] Warning: Could not find file C:\jbpm-installer\db\task-persistence.xml to copy. [copy] Warning: Could not find file C:\jbpm-installer\db\Taskorm.xml to copy. The start demo was successful. Actually when I try to open any tool provided with the jBPM such us the jBPM-console for example I’m getting the following messages: Address not found or sometimes the http status 404 occurred even if the Welcome page of jBoss AS was opened at http://localhost:8080/. Please need your assistance to sort out this issue in order to move forward in my project as I'm blocked in the installation stage since more than a week now, I don’t know if this is related to the jBoss AS7 or to any other thing that I didn’t find out. Looking forward to hearing from you. Thanks Kahina

  • What relational database system should I learn? [closed]

    - by acidzombie24
    At the moment i know sqlite (my favorite), mysql (its ok, i get annoyed) and i do not want to learn ms/t sql (it only allows one nullable row if the column is unique). I am thinking about learning a new database system. My requirements for it is Must allow multiple connections at once (read and write) All or data i choose must be ACID compliant Performance should be good. I have a 17gb table in one project. It should perform well on read and transactional writes. With mysql it took hours to restore it and there were no foreign keys on that specific table. It only finished in a workday because i found a suggestion to adjust a setting which i think was key-buffer. And it still took hours Unique columns that allow more then one row to be null. I shouldn't have to say it but dammit MS. Allows one to make ongoing backups. Something like 'binary logs'. Some relatively small amounts of data i can grab and apply it to my local db to have it in sync with the one on the server. Table joins. I rather not write a bunch of queries to simulate a join What I would like but is not required Foreign keys. This may be a requirement later Open sourced Fair tool support. So i can measure queries, easily backup/restore, etc .NET and C (or C++) interface. (I seen one that uses raw tcp with JSON which was okish) Good subquery support. Once i was working with an older version of mysql (i believe <5.1 but it could have been 5.1) and i had to write many queries to do one query because it couldn't do subqueries. Or maybe it couldnt do it efficiently and died bc of memory limitations with a huge dataset. What db system should i learn?

  • Making document storage in Sharepoint a breeze (leave the Web UI behind)

    - by deadlydog
    Hey everyone, I know many of us regularly use Sharepoint for document storage in order to make documents available to several people, have it version controlled, etc.  Doing this through the Web UI can be a real headache, especially when you have multiple documents you want to modify or upload, or when IE isn’t your default browser.  Luckily we can access the Sharepoint library like a regular network drive if we like. Open Sharepoint in Internet Explorer (other browsers don’t support the Open with Explorer functionality), navigate to wherever your documents are stored, choose the Library tab, and then click Open with Explorer. This will open the document storage in Explorer and you can interact with the documents just like they were on any other network drive J  This makes uploading large numbers of documents or directory structures super easy (a simple copy-paste), and modifying your files nice and easy. As an added bonus, you can drag and drop that location from the address bar in Explorer to the Favorites menu so that it’s always easily accessible and you can leave the Sharepoint Web UI behind completely for modifying your documents.  Just click on the new favorite to go straight to your documents.   You can even map this folder location as a network drive if you want to have it show up as another drive (e.g N: drive). I hope you found this as useful as I did

  • How can I configure the embedded wireless card in a Toshiba Satellite Pro 4600 to work under Lubuntu 10.10?

    - by MoLE
    I'm struggling to get the embedded wireless card in this laptop to work. In 7.10 (gutsy) it worked fine. Now I'm trying to get 10.10 (maverick) working on it, and am using the Lubuntu flavour due to the low resources of this laptop. The hardware: Appears to be an embedded pcmcia card. pccardctl ident gives: Socket 0: product info: "TOSHIBA", "Wireless LAN Card", "Version 01.01", "" manfid: 0x0156, 0x0002 function: 6 (network) The default kernel recognises the card and loads the orinoco_cs driver. orinoco_cs 0.0: Hardware identity 0005:0002:0001:0002 orinoco_cs 0.0: Station identity 001f:0001:0006:000e orinoco_cs 0.0: Firmware determined as Lucent/Agere 6.14 Then for some reason, the driver isn't happy with this and gives: orinoco_cs 0.0: Hardware identity 0005:0002:0001:0002 orinoco_cs 0.0: Station identity 001f:0002:0009:0030 orinoco_cs 0.0: Firmware determined as Lucent/Agere 9.48 All seems ok until I try to associate with my access point using Network Manager. eth1: Lucent/Agere firmware doesn't support manual roaming repeated about 10 times then NM gives up. According to the linuxwireless.org wiki page on this driver, this is a known issue, and I quote: Known issues Roaming and WPA_supplicant Lucent/Agere firmware doesn't support manual roaming On the Agere cards, roaming is controlled by the firmware instead of userspace. You will get the above message if userspace attempts to associate with a specific AP rather than by SSID. If you are using wpa_supplicant use ap_scan=2 mode. NetworkManager uses wpa_supplicant, so the above also applies. At this point my google-fu has failed me, and I can't find how to configure network manager to use the mystical "ap_scan=2" mode via wpa_supplicant. I have tried the following suggested solutions (from launchpad or the forums) deleting the agere* files from /lib/firmware using wicd instead of network manager combining both blacklisting the orinoco_cs driver in an attempt to force use of the hostap_cs driver instead (in case it is a prism2 card). Obviously none of them have worked for me. Any hints on how to perform the suggested workaround above? Edit: I have also confirmed working on 8.10 (intrepid) live CD.

  • Multitouch screen not detected on Asus Taichi 21DH71

    - by geekfreak
    I just bought this Ultrabook "Asus Taichi 21 DH71". This has Intel 3rd generation i7 processor and 4gb ram with 256 gb SSD. The main feature is that it is a hybrid machine. Naming it has dual screens. When the lid is closed it can be used as a tablet and when lid open it can be used as a notebook. This machine can also be used with the two screens on at the same time. I used ubuntu many years ago and loved it. But I never tried any linux later. My questions are Does the new version of Ubuntu support the Multitouch interface? Will it work specifically on this machine? Will Ubuntu support gestures on multi touchpad? Update 2/22/2013 I did try the latest 64bit Ubuntu(12.10) from live usb and noticed that it couldn't detect the tablet screen. Everything else worked seamlessly. Do you guys think the tablet screen would be detected if I make a complete installation on to the notebook? Please help guys..

  • Long 'Wait' Time for three php/CSS files. Is something blocking them?

    - by William Pitcher
    I have been speed optimizing a Wordpress site to little effect. There are three files CSS-related php files from the Wordpress theme that are delaying page loads on the site. One of the three files is basically one line of custom CSS from the custom CSS feature in the theme. You can see what I am talking about with this Pingdom speed test: The yellow is 'Wait'. There are no slow items in the cut-off portion of the image. The full results are here: Pingdom Results Page 1. Any thoughts on what might be causing this? I understand that I have blocking CSS or JS files, but I don't see anything that would be causing that long of a wait. When I ran the P3 Plugin Profiler, Wordpress and all plugins appeared fine -- it is the theme that is taking all the time. GTmetrix recommends avoiding dynamic queries. I assume all the ver=3.61 references are to the version of Wordpress (which I am using). I noticed that my Wordpress sites using other themes don't make this query (at least not over and over). 2. Is this typical coding practice? 3. How much negative impact do these query-strings have -- a little or a lot? I tried searching for similar questions here, please excuse me if I missed something. Sometimes, I know just enough to be dangerous.

  • Over-scan Issues when using HDTV through VGA

    - by RPG Master
    Right now all we can do is set the TV to 1280x768 instead of its native resolution of 1360x768. Setting it to its native resolution gives you a screen with a large portion of the left side of the screen cut off. We've tried everything with the TV so now we're turning to the innards of Ubuntu in hopes of fixing this. The computer is using an NVIDIA GeForce GT240. This is its current xorg.conf: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 1.0 (buildd@palmer) Fri Apr 9 10:35:18 UTC 2010 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: builtin, VertRefresh source: builtin # HorizSync 28.0 - 55.0 # VertRefresh 43.0 - 72.0 Identifier "Monitor0" VendorName "Unknown" ModelName "CRT-0" HorizSync 28.0 - 55.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 6600" EndSection Section "Screen" # Removed Option "metamodes" "1360x768 +0+0; 800x600 +0+0" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "TwinViewXineramaInfoOrder" "CRT-0" Option "metamodes" "1360x768 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection

  • Whats a good host for an active vBulletin site?

    - by Kyle
    I've been switching hosts using a VPS each time and I'm just really not sure I'm finding the right VPS's. I've used a VPS from burst.net & rubyringtech and I just feel like it's slowly killing my site because of the slow speed. I really don't know if it's the network or the VPS itself but I really wish to fix this. When I TOP into the VPS peak times it shows this: top - 03:18:56 up 16:33, 1 user, load average: 1.33, 1.40, 1.33 Tasks: 30 total, 1 running, 29 sleeping, 0 stopped, 0 zombie Cpu(s): 27.2%us, 13.6%sy, 0.0%ni, 59.2%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1048576k total, 679712k used, 368864k free, 0k buffers Swap: 0k total, 0k used, 0k free, 0k cached And pages take atleast a good 2-3 minutes to load. I have only like 50-60 members on the forum also. I had a shared hosting account and the forum was lightning fast.... Is a VPS a bad idea? :\ What should I do to fix this? I'm running lighttpd with xcache, and the latest mysql + php version. The server is a intel i7 2600 w/ 1gb uplink (I think the 1gb uplink is a lie because I've tested the network and the highest download speed I've seen was 20mb/s from a code.google page) All in all I've seen people talking about linode. Should I try them? I honestly don't need a dedicated server yet it's only 50-70 members online. What should I do? I really want a VPS because I enjoy root access. Does anyone have any suggestions?

  • Slight stuttering when moving windows in fresh 12.04 install

    - by Konsolkongen
    Installed Ubuntu 12.04 today and my problem is that when I'm moving the windows around my screen it doesn't feel smooth at all. Usually I can fix this by changing the refresh rate to 60Hz, but this time it doesn't help. My graphics card is a Nvidia GTX 560Ti and I've tried both the 295.40, 295.45 and 304.43 (which I'm currently using) but neither has resolved my problem. I searched around a bit and tried changing the refresh-rate using compizconfig-settings-manager and xrandr. No change using CCSM, but when I tried xrandr I got this reply: konsolkongen@konsolkongen-desktop:~$ xrandr -r 60Rate 60.0 Hz not available for this size - which is nonsense of course. This is what my xorg.conf file looks like: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 295.33 (buildd@allspice) Fri Mar 30 15:25:24 UTC 2012 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "Samsung SyncMaster" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 560 Ti" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "metamodes" "DFP-0: 1680x1050_60 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Any help would be greatly appreciated, my obsession with video quality can't stand stuttering like this. For what it's worth though, I don't have any screen tearing, so at least V-sync is on. Thanks.

  • How to choose between Tell don't Ask and Command Query Separation?

    - by Dakotah North
    The principle Tell Don't Ask says: you should endeavor to tell objects what you want them to do; do not ask them questions about their state, make a decision, and then tell them what to do. The problem is that, as the caller, you should not be making decisions based on the state of the called object that result in you then changing the state of the object. The logic you are implementing is probably the called object’s responsibility, not yours. For you to make decisions outside the object violates its encapsulation. A simple example of "Tell, don't Ask" is Widget w = ...; if (w.getParent() != null) { Panel parent = w.getParent(); parent.remove(w); } and the tell version is ... Widget w = ...; w.removeFromParent(); But what if I need to know the result from the removeFromParent method? My first reaction was just to change the removeFromParent to return a boolean denoting if the parent was removed or not. But then I came across Command Query Separation Pattern which says NOT to do this. It states that every method should either be a command that performs an action, or a query that returns data to the caller, but not both. In other words, asking a question should not change the answer. More formally, methods should return a value only if they are referentially transparent and hence possess no side effects. Are these two really at odds with each other and how do I choose between the two? Do I go with the Pragmatic Programmer or Bertrand Meyer on this?

  • Proper XAML for Windows 8 Applications [closed]

    - by Jaapjan
    Traditionally, my programs do their work in the background and when I do have to make an interface for some reason, they often do not need to be complex which means I can use a simple Windows Forms or console application. But lets be honest-- Windows Forms? That is so ... ancient! Instead I have been looking at Windows 8. A new interface, different, maybe better-- but fun to give a try. Which means XAML. Now, XAML isn't all that hard in concept. Panel here, button there-- A smattering of XML. My question in short: Where can I find resources that teach me how to write good XAML code for Windows 8 applications? The long version: How do I combine XAML constructs to achieve effects? Horizontal panels with multiple sections you can scroll through with your finger, the proper way? How should you use default style resources Windows 8 might give you by default? How do I properly create a panel with user info on the right? Left aligned stackpanels with embedded dockpanels? Yes? No? Why?

  • 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.
