• Is it possible to install ZSNES Emulator from default software sources?

  - by Mike L

  I can find it listed when I search for "zsnes" in the Ubuntu Software Center but it doesn't have the "Install" button. If I click the "More information" button I'll get a "package not found" message. Synaptic can't find this package either. (from user @REJ) I have Natty 64bit. When I run sudo apt-get install zsnes it gives the following output: Reading package lists... Done Building dependency tree Reading state information... Done Package zsnes is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'zsnes' has no installation candidate

• library put in /usr/local/lib is not loaded

  - by IARI

  Let me state in advance: One might think this question would is for server fault, but I think is is Ubuntu (config) specific. In short: I have put libwkhtmltox.so in /usr/local/lib as stated in installation instructions linked below, but it appears the library is not loaded. I am trying to install php-wkhtmltox, a php extension for wkhtmltox on my local desktop (Ubuntu 12.04). I have extracted the source and changed to the corresponding directory. After running phpize, ./configure fails at checking for libwkhtmltox support... yes, shared not found configure: error: Please install libwkhtmltox I suspect the reason the library is not loaded is that the path is not checked!? how do I proceed? Here are instructions I followed: http://davidbomba.com/index.php/2011/08/04/php-wkhtmltox/ http://roundhere.net/journal/install-wkhtmltopdf-php-bindings/

• cPanel email doesn't seem to work - error 550?

  - by Megh

  I am fairly new to the web hosting game, so bear with me :) Recently set up a VPS with cPanel and WHM. Everything is going well so far, I've created a user domain and transferred my website there, managed a couple of databases with phpmyadmin, everything was going great until I started messing around with email. I made an email account [email protected] through cPanel, although when I try and email this address I get the following error: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Unknown user (state 13) Quite unsure of what to do next, in all honesty.

• Getting rid of getting stuck often [closed]

  - by Pankaj Upadhyay

  I have been working with C# and .NET for around 2-3 years. But, still i get stuck too often. My project includes few simple websites(asp.net) in the early parts and then a desktop application for cotton transaction management(wpf). And right now, I am building a price compare website (asp.net MVC). Along the lines, I have read quite few books on C# and .NET, but still I get stuck very often. What pisses me is that the problems I get stuck in aren't very typical or hard. You can get a better idea by visiting my questions page on SO. After looking at my question lists, do you also feel that my basis or knowledge as a programmer are weak ? If so, How can i find a remedy to this problem ? And How can I stop getting stuck too often for simpler problems.

• Compute if a function is pure

  - by Oni

  As per Wikipedia: In computer programming, a function may be described as pure if both these statements about the function hold: The function always evaluates the same result value given the same argument value(s). The function result value cannot depend on any hidden information or state that may change as program execution proceeds or between different executions of the program, nor can it depend on any external input from I/O devices. Evaluation of the result does not cause any semantically observable side effect or output, such as mutation of mutable objects or output to I/O devices. I am wondering if it is possible to write a function that compute if a function is pure or not. Example code in Javascript: function sum(a,b) { return a+b; } function say(x){ console.log(x); } isPure(sum) // True isPure(say) // False

• How can I let prospective employers know I'm a great developer?

  - by Zoe Gagnon

  I've recently read through Joel's guide to finding great developers (http://www.joelonsoftware.com/articles/FindingGreatDevelopers.html), and I feel really strongly that I am smart and get things done. The problem is, I didn't learn how to get things done until about halfway through college, so my GPA is less than stellar. Additionally, I've got a few other things going against me: late into the job market (~30), no internship, state college instead of university, and when I graduated, I pretty much had to take the first job that offered. With all of these things piled together, my resume (the first step to getting a job), is not terribly impressive. What can I do to let people know that I'm a great developer and would complement the best companies in the world?

• Numpad doesn't work after booting up - forced to reconnect USB keyboard after startup

  - by HorusKol

  I've tried this on two different USB keyboards - both of which work fine on a different computer running Windows XP. For some reason, the numerical keypad doesn't work probably immediately after booting up - neither the numbers work, nor the 'home' commands and so on that you can use with the numlock off. It doesn't make a difference whether I press numlock on or off - the keypad doesn't work correctly no matter what state this is in. However, once I've booted the machine I can disconnect/reconnect the USB connector for the keyboard, and it will work exactly as expected. I'm running Gnome on Ubuntu 10.04. The only other USB devices connected is a mouse - and I've experienced no problems with that. This is a direct connection to the box (not via an external USB hub)

• What should be allowed inside getters and setters?

  - by Botond Balázs

  I got into an interesting internet argument about getter and setter methods and encapsulation. Someone said that all they should do is an assignment (setters) or a variable access (getters) to keep them "pure" and ensure encapsulation. Am I right that this would completely defeat the purpose of having getters and setters in the first place and validation and other logic (without strange side-effects of course) should be allowed? When should validation happen? When setting the value, inside the setter (to protect the object from ever entering an invalid state - my opinion) Before setting the value, outside the setter Inside the object, before each time the value is used Is a setter allowed to change the value (maybe convert a valid value to some canonical internal representation)?

• Managed Service Accounts (MSA) and Virtual Accounts

  Windows Server 2008 R2 and Windows 7 have two new types of service accounts called Manage Service Accounts (MSA) and Virtual Accounts.  These make long term management of service account users, passwords and SPNs much easier. Consider the environment at OrcsWeb.  As a PCI Compliant hosting company, we need to change all security related passwords every 3 months.  This is a substantial undertaking each time because of hundreds of passwords spread throughout our enterprise.  We...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• How can I disable Hibernate completely?

  - by Lekensteyn

  I have seen the answer on How to disable hibernating?, but I have no such file. Possibly because that suggestion was written for Ubuntu, not Kubuntu (KDE, not Gnome). I do not have a swap on my encrypted SSD, my system freezes (cannot even change Caps Lock) if I accidentally press the "Hibernate" button at "Energy management". My keyboard has a Hibernate button (Fn + F4) next to the volume control buttons and every time I press the wrong key, the system will freeze after. So, what is the correct way to disable it? If there is no solution, a work-around is welcome too.

• About Alpha blending sprites in Direct3D9

  - by ambrozija

  I have a Direct3D9 application that is rendering ID3DXSprites. The problem I am experiencing is best described in this situation: I have a texture that is totally opaque. On top of it I draw a rectangle filled with solid color and alpha of 128. On top of the rectangle I have a text that is totally opaque. I draw all of this and get the resulting image through GetRenderTarget call. The problem is that on the resulting image, on the area where the transparent rectangle is, I have semi transparent pixels. It is not a problem that the rectangle is transparent, the problem is that the resulting image is. The question is how to setup the blending so in this situation I don't get the transparent pixels in the resulting image? I use the sprite with D3DXSPRITE_ALPHABLEND which sets the device state to D3DBLEND_SRCALPHA and D3DBLEND_INVSRCALPHA. I tried couple of combinations of SetRenderState, like D3DBLEND_SRCALPHA, D3DBLEND_DESTALPHA etc., but couldn't make it work. Thanks.

• Replace Broadcom "wl" driver with "b43"

  - by Laszlo Boros

  I'm using Ubuntu 10.04.4 LTS, and in my laptop there is a Broadcom BCM4312 wlan card. lspci output: 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) Subsystem: Broadcom Corporation Device 04b5 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at f4500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number 81-ac-1d-ff-ff-12-54-92 Capabilities: [16c] Power Budgeting Kernel driver in use: wl Kernel modules: wl, ssb So as you can see, the current (and default) driver is wl - installed with jockey. But I have another Ubuntu based distribution on my laptop (BackTrack linux), which is also 10.04, but it has the b43 driver installed and the overall performance is MUCH better. So I would like to install it on this OS too, but even google didn't help me. So my question is how to install the latest b43 driver on my Ubuntu?

• Effective template system

  - by Alex

  I'm building a content management system, and need advice on which theming structure should I adopt. A few options (This is not a complete list): Wordpress style: the controller decides what template to load based on the user request, like: home page / article archive / single article page etc. each of these templates are unrelated to other templates, and must exist within the theme the theme developer decides if (s)he want to use inner-templates (like "sidebar", "sidebar item"), and includes them manually where (s)he thinks are needed. Drupal style: the controller gives control to the theme developer only to inner-templates; if they don't exist it falls back internally to some default templates (I find this very restrictive) Funky style: the controller only loads a "index.php" template and provides the theme developer conditional tags, which he can use to include inner-templates if (s)he wants. Among these styles, or others what style of template system allows for fast development and a more concise design and implementation.

• Nodes can't connect to server after bootstrap

  - by user84471

  I installed maas and I was able to add nodes and they became in ready state. I executed: juju bootstrap And then one of my nodes is waking up and I receive this message on server (after juju status): And this message is shown on node after it wakes up: I am doing this several times and each time I receive the same result. I think something is wrong with my network. It look like this: internet <-> router <-> switch <-> nodes | |<----->server Router is used as a DHCP Server. It's ip is 192.168.0.1 - it's my default gateway. When I was installing maas server I installed dnsmasq and I have used as a range 192.168.0.5-192.158.0.200 and for gateway I used 192.168.0.1 and for domain I used nothing. I was able to add nodes without problems. What maybe the problem not letting nodes to connect to maas server?

• Cloud Control 12c: Verteilen von beliebiger Software mit Deployment Prozeduren

  - by Ralf Durben (DBA Community)

  Mit dem Lifecycle Management Pack von Oracle Enterprise Manager Cloud Control 12c können Sie Software aus der grafischen Konsole heraus auf Zielsysteme verteilen und installieren, also provisionieren. Dieses funktioniert für viele Oracle Produkte in einer vorgefertigen Form unter Verwendung von Deployment Prozeduren, die als eine Art Spezialformat für Provisionierungsskripte angesehen werden können. Dabei können die vorgefertigten Deployment Prozeduren direkt oder für die eigenen Bedürfnisse modifiziert verwendet werden. Sie können diese Technik jedoch auch für die Provisionierung beliebiger Software nutzen, indem Sie eigene Deployment Prozeduren erstellen. Als einfaches Beispiel einer solchen Provisionierung soll in diesem Tipp das Verteilen einer ZIP-Datei mit anschliessendem Auspacken betrachtet werden. Bewusst wird in diesem Tipp versucht, das Beispiel einfach zu halten, um einen leichten Einstieg zu ermöglichen. Dieser Tipp zeigt Ihnen, wie Sie eine ZIP-Datei mit einer selbstgeschriebenen Deployment Prozedur provisionieren können.

• Conways Game of Life C#

  - by Darren Young

  Hi, Not sure if this is the correct place for this question or SO - mods please move if necessary. I am going to have a go at creating GoL over the weekend as a little test project : http://en.wikipedia.org/wiki/Conway's_Game_of_Life I understand the algorithm, however I just wanted to check regarding the implementation, from maybe somebody that has tried it. Essentially, my first (basic) implementation, will be a static grid at a set speed. If I understand correctly, these are the steps I will need: Initial seed Create 2d array with initial set up Foreach iteration, create temporary array, calculating each cells new state based on the Game of Life algorithm Assign temp array to proper array. Redraw grid from proper array. My concerns are over speed. When I am populating the grid from the array, would it simply be a case of looping through the array, assigning on or off to each grid cell and then redraw the grid? Am I on the correct path?

  Murali Papana from our Human Capital Management (HCM) Fusion Applications team has posted a series of blogs on a lesser-known, but quite powerful feature of ADF called "date effectivity". This is a feature that allows the framework to simplify managing records whose data values are effective for a given period of time. Imagine an employee's job title or salary that changes over time, which as well might be entered today by an HR reprepsentative but go into effect at some time in the future.
