• Releasing poorly written software...

  - by eddienotizzard

  I've made a poorly written, yet fully functioning website, in (shock, horror, shock) PHP. Everything works as expected, I've implemented the necessary security measures: http://php.net/manual/en/security.php and phpsec.org/projects/guide/ It's poorly written in the sense that it's a bunch of functions thrown together that do something...oddly enough I was consistent with the naming conventions. Would you release something you were not happy with, but worked? I would also like to point out that I don't collect much user information (username, email and password) is about it -- but it's not really the security part I'm worried about, it's the spaghetti code I've written.

• How do I toggle the wifi hardware switch for a Dell XPS 17 L702X?

  - by Sparhawk

  Every now and then, I disable my wireless via the menu icon in Ubuntu. Then, when I try to enable the wifi, it tells me that "wireless is disabled" or "wireless is disabled by hardware switch". There is a red icon on the F2 key that looks like a wireless icon, and in Windows, pressing the (red) Fn key and F2 toggles the wifi. This does not work in Ubuntu, leaving me no clear way to turn wifi back on. How can I restart wifi in Ubuntu?

• Unity, changing gravity game & stopping character when he hit a wall.

  - by Sylario

  i am currently working on a 2d puzzle game in the unity engine. One of the aspect of this game is the possibility to rotate the level of 90°. It also rotate the gravity. The main character is not directly controlled by the player, but instead fall when the level is rotated. When the main character hit a wall, he should stop to move. If i do not stop it, it kind of blink ans shake against the wall. To stop it i detect collision and depending on the current rotation state, the player will stop at "vertical" or "horizontal" tags when a OnCollisonEnter occurs. I must do that because when the player fall on his relative ground, He must not stop like if he had touch a wall. My problem is the 'side' of platform, or the 'top' of wall, they use the same tag and thus do not give the correct tag to my character. I tried to put a very small invisible box on top/side of elements but the collision occurs nevertheless. It seems when the player falls and hit something he go through a bit before being replaced at correct position by unity. Is there a way : 1 ) to doesn't stop my character but to make it appear immobile on screen 2 ) To detect a "i cannot move anymore" collision other than by using collision?

• How to create one additional hidden partition in a USB drive

  - by backslash17

  For security purposes I need to locate a additional hidden partition on USB flash drive. The USB drive contains a security application that will check (in code) if the hidden partition exists. If not I will assume that the application is a non valid copy. Any idea about it? Thanks in advance. EDIT: There is already a programmed secure method to check if the USB drive is correct using the WMI Win32_drive class. The idea is to locate the drive info into the hidden partition and to check if it correct for anti-tampering procedures.

• Red Hat 5.4 slow processing

  - by yucefrizk

  I'm running Red Hat Linux 5.4 on HP DL580 server with 16 processors and 64 GB of RAM. I'm connecting to the server remotely through SSH. after entering the password, it takes time to return the command line, if I click ctrl+c during this time, I'll have the command line prompt but not the correct bash prompt (I have to run bash to pass to my correct prompt). I tried to install Apache on the server, ./configure took 4 hours to finish instead of 1 or two minutes, Oracle installation same behavior. Server Disks are mirrored using RAID controller. any idea what could be the reason of this slowness?

• WiFi AdHoc Network: Unable to access peer by ip

  - by Pranav

  I've set up a WiFi AdHoc network in Maverick and selected the IPv4 settings as "Shared to other computers". On the client computer, I joined the network with the same SSID and set IPv4 method to Manual and I gave it an IP 10.42.43.2 (As on the first computer, the auto generated IP was 10.42.43.1). From either of the computers, I'm not able to access the other using the IP (in browser). Any idea why? (If I browse to 10.42.43.1 from the first computer, it works) Thanks!

• custom domain point to tumblr blog

  - by Julius

  My domain mydomain.com is registered with godaddy. I wish to host my tumblr blog on this domain with nearlyfreespeech.net hosting. My active nameservers at godaddy already point to my authoritative ones at NFS.net which is working. However i'm baffled of the correct configuration to set to point to my Tumblr. Preferably id like (A) my domain http://mydomain.com to host the blog and have http://www.mydomain.com redirect also to http://mydomain.com If this is too difficult my next preference is (B) to have http://www.mydomain.com host the blog whilst http://mydomain.com redirects to http://www.mydomain.com My 3rd preference is to have (C) a sub-domain like http://tumblr.mydomain.com or http://tumblr.mydomain.com to host the blog and i guess have http://mydomain.com and http://www.mydomain.com both redirect to it. I've tried having two aliases mydomain.com and www.mydomain.com pointing to my permanent NFS ip at mydomain.nfshost.com and when i try to add: (1) an A record pointing mydomain.com to the ip 66.6.44.4 as per Tumblr's instructions it tells me i already have the bare domain as an alias so i cant do that. (2) the A record on the www.mydomain.com alias. I can do this with either www.mydomain.com set as an alias or not. But when i tried this with mydomain.com set as the canonical name the result when visiting either mydomain.com or www.mydomain.com was them both continually redirecting to eachother until an error was thrown. So i was wondering if there is a ninja that could save me some hairpulling and tell me the correct way to config A, or else B, or else C.

• Loose Coupling and UX Patterns for Applications Integrations

  - by ultan o'broin

  I love that software architecture phrase loose coupling. There’s even a whole book about it. And, if you’re involved in enterprise methodology you’ll know just know important loose coupling is to the smart development of applications integrations too. Whether you are integrating offerings from the Oracle partner ecosystem with Fusion apps or applications coexistence scenarios, loose coupling enables the development of scalable, reliable, flexible solutions, with no second-guessing of technology. Another great book Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions tells us about loose coupling benefits of reducing the assumptions that integration parties (components, applications, services, programs, users) make about each other when they exchange information. Eliminating assumptions applies to UI development too. The days of assuming it’s enough to hard code a UI with linking libraries called code on a desktop PC for an office worker are over. The book predates PaaS development and SaaS deployments, and was written when web services and APIs were emerging. Yet it calls out how using middleware as an assumptions-dissolving technology “glue" is central to applications integration. Realizing integration design through a set of middleware messaging patterns (messaging in the sense of asynchronously communicating data) that enable developers to meet the typical business requirements of enterprises requiring integrated functionality is very Fusion-like. User experience developers can benefit from the loose coupling approach too. User expectations and work styles change all the time, and development is now about integrating SaaS through PaaS. Cloud computing offers a virtual pivot where a single source of truth (customer or employee data, for example) can be experienced through different UIs (desktop, simplified, or mobile), each optimized for the context of the user’s world of work and task completion. Smart enterprise applications developers, partners, and customers use design patterns for user experience integration benefits too. The Oracle Applications UX design patterns (and supporting guidelines) enable loose coupling of the optimized UI requirements from code. Developers can get on with the job of creating integrations through web services, APIs and SOA without having to figure out design problems about how UIs should work. Adding the already user proven UX design patterns (and supporting guidelines to your toolkit means ADF and other developers can easily offer much more than just functionality and be super productive too. Great looking application integration touchpoints can be built with our design patterns and guidelines too for a seamless applications UX. One of Oracle’s partners, Innowave Technologies used loose coupling architecture and our UX design patterns to create an integration for a customer that was scalable, cost effective, fast to develop and kept users productive while paving a roadmap for customers to keep pace with the latest UX designs over time. Innowave CEO Basheer Khan, a Fusion User Experience Advocate explains how to do it on the Usable Apps blog.

• smbmount returns "operation not permitted"

  - by Petriborg

  I use the smbfs tools package to mount my SMB shares. I wrote a quick script to mount the share: #!/bin/sh /usr/bin/smbmount "\\\\somehost.local\\hostshare" /media/hostshare -o user=smbuser,dom=WORKGROUP,uid=localuser,gid=localgroup This script used to work in 9.10 when called by the "localuser" account, but in my fresh-installed 10.04 it fails giving me the error: mount error(1): Operation not permitted Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) The /media/hostshare directory is empty and has these perms: drwxrwxr-x 2 localuser localgroup 4096 2010-12-12 12:04 hostshare/ The "localuser" is in these groups: localgroup adm dialout cdrom plugdev lpadmin admin sambashare Any idea what is going on here? Google seems to suggest that the "sticky" bit needs to be set on /sbin/mount.cifs /sbin/mount.smbfs and /sbin/umount.cifs Is this a bug?

• Herding Cats - That's My Job....

  - by user709270

  Written by Mike Schmitz - Sr. Director, Program Management Oracle JD Edwards  I remember seeing a super bowl commercial several years ago showing some well dressed people on the African savanna herding cats. I remember turning to the people I was watching the game with and telling them, “You just watched my job description”. Releasing software is a multi-facetted undertaking. In addition to making sure the code changes are complete, you also need to make sure the other key parts of a release are ready. For example when you have a question about the software, will the person on the other end of the phone be ready to answer your question? If you need training on that cool new piece of functionality, will there be an online training course ready for you to review? If you want to read about how the software is supposed to function, is there a user manual available? Putting all the release pieces together so they are available at the same time is what the JD Edwards Program Management team does. It is my team’s job to work with all the different functional teams so when a release is made generally available you have all the things you need to be successful. The JD Edwards Program Management team uses an internal planning tool called the Release Process Model (RPM) to ensure all deliverables are accounted for in a release. The RPM makes sure all the release deliverables are ready at the correct time and in the correct format. The RPM really helps all the functional teams in JD Edwards know what release deliverables they are accountable for and when they are to be delivered. It is my team’s job to make sure everyone understands what they need to do and when they need to deliver. We then make sure they are all on track to deliver on-time and in the right format. It is just that some days this feels like herding cats.

• Single-Click Checkbox in RadGridView

  - by Anthony Trudeau

  Originally posted on: http://geekswithblogs.net/tonyt/archive/2014/06/05/156809.aspxThe Telerik RadGridView for WPF is a flexible visual control for displaying and manipulating tables of data. It’s not without it’s quirks though. I ran into one of those quirks recently. The behavior of the RadGridView requires that you first activate the cell for editing. That enables the editing controls underneath. Although that provides better editing capabilities, it also can be unintuitive. In my case I don’t want my users to have to click a checkbox value twice in order to change the value. This can be solved easily by setting the EditTriggers and AutoSelectOnEdit properties to CellClick and True respectively. Unfortunately, the story doesn’t end there. You would think you could set those properties in a style with a TargetType of GridViewCheckBoxColumn. You’d be wrong. <!-- This works --> <telerik:GridViewCheckBoxColumn Header="Flag #1"       DataMemberBinding="{Binding Flag1}"       EditTriggers="CellClick" AutoSelectOnEdit="True"/> <!-- This doesn’t work --> <Style TargetType="{x:Type telerik:GridViewCheckBoxColumn}">       <Setter Property="EditTriggers" Value="CellClick" />       <Setter Property="AutoSelectOnEdit" Value="True" /> </Style> Telerik told me that is the correct, expected behavior, because the columns in the RadGridView are not visual elements. Their explanation is that the Style property comes from the base class FrameworkContentElement, but the column objects aren’t visual elements. That may be an implementation truth, but that doesn’t make the behavior correct or expected. It’s unintuitive that the GridViewCheckBoxColumn exposes a Style property that cannot be used properly, but there it is. At least there’s a way to get the desired effect.

• Can web applications running on IIS7 Windows Server 2008 R2 be forced to immediately detect changes to hosts file?

  - by Brenda Bell

  We have several web applications running on several load-balanced servers. We want to have our web applications communicate with each other without first traversing outside the load balancer. For example: http://appA.example.com is running on 192.0.2.1 and 192.0.2.2 http://appB.example.com is also running on 192.0.2.1 and 192.0.2.2 The load balancer's public IP address is 198.51.100.3 By default, when appA on 192.0.2.1 makes a call to a WCF service hosted in appB, the HTTP request is routed to 192.51.100.3; this establishes a new session and the load balancer will direct the call to either of the two servers We want the call to be routed to the instance of appB running on the same server so we add 192.0.2.1 appB.example.com to the hosts file on 192.0.2.1. This eventually works, but we either have to wait for the app pool to naturally recycle or do a manual reset before appA sees the new address. Is there any way to have the change automatically detected without having to recycle the app pool?

• What is the recommended MongoDB schema for this quiz-engine scenario?

  - by hughesdan

  I'm working on a quiz engine for learning a foreign language. The engine shows users four images simultaneously and then plays an audio file. The user has to match the audio to the correct image. Below is my MongoDB document structure. Each document consists of an image file reference and an array of references to audio files that match that image. To generate a quiz instance I select four documents at random, show the images and then play one audio file from the four documents at random. The next step in my application development is to decide on the best document schema for storing user guesses. There are several requirements to consider: I need to be able to report statistics at a user level. For example, total correct answers, total guesses, mean accuracy, etc) I need to be able to query images based on the user's learning progress. For example, select 4 documents where guess count is 10 and accuracy is <=0.50. The schema needs to be optimized for fast quiz generation. The schema must not cause future scaling issues vis a vis document size. Assume 1mm users who make an average of 1000 guesses. Given all of this as background information, what would be the recommended schema? For example, would you store each guess in the Image document or perhaps in a User document (not shown) or a new document collection created for logging guesses? Would you recommend logging the raw guess data or would you pre-compute statistics by incrementing counters within the relevant document? Schema for Image Collection: _id "505bcc7a45c978be24000005" date 2012-09-21 02:10:02 UTC imageFileName "BD3E134A-C7B3-4405-9004-ED573DF477FE-29879-0000395CF1091601" random 0.26997075392864645 user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioFiles [ 0 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "English" date 2012-09-22 01:15:04 UTC } 1 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "Spanish" date 2012-09-22 01:17:04 UTC } ]

• Help accessing Beagle over serial with Minicom/GTKTerm

  - by mrgordon

  I am trying to access a brand new Beagle Board from Ubuntu or Mac over serial using the setup seen here: http://specialcomp.com/beagleboard/RevC1.htm I got Minicom and GTKTerm installed on the Ubuntu box. I set up the correct baud rate, turned off flow control, and have tried ttyUSB0 and ttyS0. Once minicom is configured properly, I should just see the init text from the board appear if I have minicom open in terminal while I plug in the board, correct? dmesg shows ttyUSB0 on the computer has been connected to ttyS0 on the beagle.

• HTML5 Canvas Converting between cartesian and isometric coordinates

  - by Amir

  I'm having issues wrapping my head around the Cartesian to Isometric coordinate conversion in HTML5 canvas. As I understand it, the process is two fold: (1) Scale down the y-axis by 0.5, i.e. ctx.scale(1,0.5); or ctx.setTransform(1,0,0,0.5,0,0); This supposedly produces the following matrix: [x; y] x [1, 0; 0, 0.5] (2) Rotate the context by 45 degrees, i.e. ctx.rotate(Math.PI/4); This should produce the following matrix: [x; y] x [cos(45), -sin(45); sin(45), cos(45)] This (somehow) results in the final matrix of ctx.setTransform(2,-1,1,0.5,0,0); which I cannot seem to understand... How is this matrix derived? I cannot seem to produce this matrix by multiplying the scaling and rotation matrices produced earlier... Also, if I write out the equation for the final transformation matrix, I get: newX = 2x + y newY = -x + y/2 But this doesn't seem to be correct. For example, the following code draws an isometric tile at cartesian coordinates (500, 100). ctx.setTransform(2,-1,1,0.5,0,0); ctx.fillRect(500, 100, width*2, height); When I check the result on the screen, the actual coordinates are (285, 215) which do not satisfy the equations I produced earlier... So what is going on here? I would be very grateful if you could: (1) Help me understand how the final isometric transformation matrix is derived; (2) Help me produce the correct equation for finding the on-screen coordinates of an isometric projection. Many thanks and kind regards

• Configuring Network without Default Gateway

  - by Homayoon

  I'm trying to connect my desktop and laptop using an ethernet connection. I usually configure network from the command line but this time I decided to give Network Manager a try, so I went to Network Connections, and selected manual IP configuration. At first I left the default gateway field blank, since I don't need a default gateway. Turned out network manager doesn't let me save the connection unless I enter that field, but entering a phony gateway messes up with my Internet connection. Anyway to do this setup?

• BizTalk Schema Validation

  - by Christopher House

  Perhaps this one should be filed under:  Obvious Yesterday I created a new schema that is going to be used for a WCF receive.  The schema has a bunch of restrictions in it, with the intention that we'd validate incoming messages against the schema.  I'd never done message validation with BizTalk but I knew the XmlDisassembler component had an option for validating, so I figured it would be a piece of cake.  Sadly, that was not to be the case.  I deployed my artifacts and configured my receive location's XmlDisassembler with what I thought to be the correct document spec name.  I entered My.Project.Name.SchemaTypeName for the document spec and started running unit tests.  All of them failed with the following error logged in the event log: "WcfReceivePort_BizTalkWcfService/PurchaseOrderService" URI: "/BizTalkWcfService/PurchaseOrderService.svc" Reason: No Disassemble stage components can recognize the data. I went to the receive port and turned on tracking, submitted another message, then went to the admin console and saved the message.  It looked correct, but just to be sure, I manually validated it against the schema in my project.  As expected, it validated correctly. After a bit of thinking on this, I realized that I probably needed to fully qualify my document spec name, meaning, include the assembly name, as well as the type name.  So, I went back to the receive location and changed the document spec to: My.Project.Name.SchemaTypeName, My.Project.Name,Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxx I re-ran my unit tests and everything was working as expected.  So, note to self:  remember to include the assembly name when setting the document spec.  If you need an easy way to determine your schema name and assembly name, find your schema in the admin console and go to it's properties.  On the property screen, look at the Name and Assembly properties.  Your document spec will be "SchemaName, AssemblyName"

• Bending of track in a racing game

  - by caius

  I am trying to create a small racing game in which the track would be modeled using a BSpline curve for the path's center line and directional vectors to define the 'bending' of the track at each point. My problem is that I don't know how to calculate the correct bending / slope of the curve, in such a way that it would be optimal or at least visually nice for a car to 'bend in the corner'. My idea was to use the direction of the 2nd derivatives of the curve, however while this approach looks fine for most of the track, there are points in which the 2nd derivative makes sharp 'twists' / very quick 180 degree flips. I also read about 'knots' of bsplines, but I don't know if such 'twist' in 2nd derivatives is a knot or knots are something else. Can you tell me that using a BSpline: 1. How could I calculate a visually nice bending of a track for a racing game? 2. Is it possible to do this by using some simple calculations of centripertal force / gravity? 3. Is it possible to do this by using 1st, 2nd and 3rd derivatives of the BSpline curve? I am not looking for the 'physically correct' bending angle for the track, I would just like to create something which is visually pleasing in a simple game. I am using a framework which has a built-in class for BSpline, including support for 1st, 2nd and 3rd derivatives of the curve.

• Nautilus statusbar visibilty - Quickly check free space

  - by Jeremy

  In prior versions, I would open Nautilus and check the statusbar, which would tell me how much free space there is. Now, the statusbar isn't shown by default. I know you can enable it from the View menu, but 99% of users won't do that (and I'd rather not do that, if possible). So, is there some new recommended way to keep tabs on hard drive usage? Or is there maybe some other method that I should have been using in the past but never noticed?

• Word to GIMP pasted image too small

  - by Marcelo Cantos

  I paste an image from Microsoft Word 2010 into GIMP 2.6.10 using Edit ? Paste as ? New Image, but the pasted image is less than half-size (1280×800 down to 553×347). Pasting into an existing blank 1280×800 image makes no difference. On the other hand, pasting exactly the same clipboard entry into Windows Paint works beautifully, producing a razor-sharp 1280×800 image, and furthermore, pressing Ctrl+C in Paint, then going to Gimp and pressing Shift+Ctrl+V in Gimp produces the correct full-size image in Gimp too. Why does pasting an image directly from Word to Gimp reduce the image size? How can I make it paste the correct image size without having to go via Paint? UPDATE: I just noticed that cutting the image from Word and pasting back into the same document also loses definition. Paint must be magical.

• How should I synchronize configurations and data across computers?

  - by lfaraone

  Imagine I have three Ubuntu computers home, laptop, beach-house. They all have the same version of Ubuntu, 10.04 installed, and are kept up to date from the repositories. I use f-spot, thunderbird, and google-chrome on all of the computers. Is there a way to keep the data and configuration in sync across them, without requiring constant connectivity for normal (non-synchronous) usage? For example, they should be usable without network connectivity, so something like NFS won't work. An ideal solution would not require manual action to start the syncing process.

In order to get them functioning again I have to open the tweak tool and turn hotcorners off and then back on after every reboot. This I admit isn't a huge issue but is annoying is there anyway to get hotcorners to work properly after reboot with out having to reset them every time?
