• A tip: Updating Data in SharePoint 2010 using REST API

  - by Sahil Malik

  SharePoint 2010 Training: more information Here is a little tip that will save you hours of head scratching. See there are two ways to update data in SharePoint using REST based API. A PUT request is used to update an entire entity. If no values are specified for fields in the entity, the fields will be set to default values. A MERGE request is used to update only those field values that have changed. Any fields that are not specified by the operation will remain set to their current value.   Now, sit back and think about it. You are going to update the entire entity! Hmm. Which means, you need to a) specify every column value, and b) ensure that the read only values match what was supplied to you. What a pain in the donkey! So 99/100 times, a PUT request will give you a HTTP 500 internal server error occurred, which is just so helpful. Read full article ....

• trying to setup multiple primary partitions on ubuntu linux

  - by JohnMerlino

  I currently have ubuntu desktop installed on a harddrive. I want to partition the harddrive so that I can reserve 30 gigs for ubuntu server and 30 gigs for ubuntu desktop. The drive has 300 gigs available. Right now I am booting from dvd drive and installing ubuntu server. I selected "Guided partitioning" and created a 30 gig primary partition of Ext4 journaling filesystem, set "yes, format it" for format partition and set bootable flag to on. I intend to use this 30 gig partition to hold ubuntu server and allow me to boot from it. Now I have two other partitions. They are both set to "logical", one is currently using 285.8 gigs and is using ext4 (when I try to set bootable flag to true, it gives a warning "You are trying to set the bootable flag on a logical partition. The bootable flag is only useful on the primary partitions"). More alarming it says "No existing file system was detected in this partition". Actually, Im thinking that this is the parittion that is supposed to be holding my current Ubuntu Desktop. And of course I want this to be bootable and be a primary partition, so I could dual boot from this and the server partition. Now the third partition is also set to logical and it is being used as swap area. My question is regarding that second partition. Its supposed to be a primary partition thats holding my existing ubuntu desktop edition. How do I switch it to primary and to make sure that its pointing to my existing desktop installation?

• How to display password policy information for a user (Ubuntu)?

  - by C.W.Holeman II

  Ubuntu Documentation Ubuntu 9.04 Ubuntu Server Guide Security User Management states that there is a default minimum password length for Ubuntu: By default, Ubuntu requires a minimum password length of 4 characters Is there a command for displaying the current password policies for a user (such as the chage command displays the password expiration information for a specific user)? > sudo chage -l SomeUserName Last password change : May 13, 2010 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7 This is rather than examining various places that control the policy and interpreting them since this process could contain errors. A command that reports the composed policy would be used to check the policy setting steps.

• Update Billing Email Addresses in Sage MAS90

  - by ThaKidd

  I have been tasked with trying to find a method of updating about 500 customer email addresses in MAS90. I recently discovered that they had the ability to email invoices to their customers and because I opened my big mouth, they now want me to find a way to add about 500 emails into the system so they do not have to perform the task manually. The office does have an SQL server which supports ASP sites which contains a list of all of the current email addresses. My plan was to use Microsoft Access 2007 with the MAS90 ODBC connector to attempt this update. My questions are: Is this the right way to go or is there a better method of obtaining these results? Does anyone happen to know which tables I should be looking at? Any and all help is appreciated. Thanks in advance!

• Ternary and Artificial Intelligence

  - by user2957844

  Not much of a programmer myself, however I have been thinking about the future of AI. If a fully functional AI is programmed in a binary environment as is used in current computing, would that create a bit of a black and white personality? As in just yes/no, on/off, 1/0? I will use the Skynet computer from the Terminator series as a bad analogy; it is brought online and comes to the conclusion that humanity should just be destroyed so the problem is resolved, basically its only options were; fire the missiles or not. (The films do not really go into what its moves would be after doing such a thing, but that goes into the realms of AI evolution so does not really fit with this question.) It may also have been badly programmed. Now, the human mind has been akin to a ternary system which allows our "out of the box" thinking along with all the other wonderful things our minds can do. So, would it not be more prudent to create a functional ternary system and program an AI using it so the resulting personality would be able to benefit from the third "maybe" (so to speak) option? I understand that in binary there are ways to get around the whole yes/no etc. way of things, however the basic operations are still just 1's and 0's. Again with using the above bad Skynet analogy; if it could have had that third "maybe" option as part of its core system, it may have decided to not launch due to being able to make sense of the intricacies of human nature and the politics of such a move etc. In effect, my question is; Would an AI benefit more from ternary computing as opposed to binary due to the inclusion of -1, or 2, dependent on the system ("maybe," as I call it)?

• How can I get the mount path of a USB device on OSX?

  - by xastor

  I have a backup script that backs up some data to a USB device. The problem I have is that OSX sometimes changes the expected mount path. For example if some file is locked under the expected mount path, OSX mounts it on another path. A USB device named 'BACKUP' can be mounted at /Volumes/BACKUP-1 instead of /Volumes/BACKUP. Is there a way to finding out the current mount path of a USB device in the OSX Terminal? Something like 'mount_path BACKUP' (command is fake) which would then return '/Volumes/BACKUP-1' or nothing if the device was not mounted?

• Fixing Broken Groups

  - by themaestro

  Hey, I just got onto a new project with the student government at my University and we're trying to get our webserver into a more workable state. The current problem is that all of us for some reason have sudo power on the server, but we can't write/create files anywhere on the server (as far as we can tell) currently. Our groups are currently as follows: /srv/ice/db$ groups goshri sshamim rmenezes goshri : goshri sshamim : sshamim ptx rmenezes : rmenezes ptx daifotis : daifotis ptx We added a few of us to ptx because we thought that might give us write access but it didn't. We have a bunch of webapps running on this server but since it's university things change hands quickly. What can we do to give us read access?

• Make a basic running sprite effect

  - by PhaDaPhunk

  I'm building my very first game with XNA and i'm trying to get my sprite to run. Everything is working fine for the first sprite. E.g : if I go right(D) my sprite is looking right , if I go left(A) my sprite is looking left and if I don't touch anything my sprite is the default one. Now what I want to do is if the sprite goes Right, i want to alternatively change sprites (left leg, right leg, left leg etc..) xCurrent is the current sprite drawn xRunRight is the first running Sprite and xRunRight1 is the one that have to exchange with xRunRight while running right. This is what I have now : protected override void Update(GameTime gameTime) { float timer = 0f; float interval = 50f; bool frame1 = false ; bool frame2 = false; bool running = false; KeyboardState FaKeyboard = Keyboard.GetState(); // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); if ((FaKeyboard.IsKeyUp(Keys.A)) || (FaKeyboard.IsKeyUp(Keys.D))) { xCurrent = xDefault; } if (FaKeyboard.IsKeyDown(Keys.D)) { timer += (float)gameTime.ElapsedGameTime.TotalMilliseconds; if (timer > interval) { if (frame1) { xCurrent = xRunRight; frame1 = false; } else { xCurrent = xRunRight1; frame1 = true; } } xPosition += xDeplacement; } Any ideas...? I've been stuck on this for a while.. Thanks in advance and let me know if you need any other part from the code.

The primary requiremen is that I need to be able to forward ports to my desktop. How would I achieve this? Is there something like "double port forwarding"? Could anyone please explain this configuration to me? Thank you in advance!

• USB port causing device problems after new motherboard upgrade

  - by enbuyukfener

  I'm looking into a PC with an issue with one of the front USB ports (perhaps both). It was working before a motherboard upgrade but since then, a USB drive was inserted, overheated and does not appear to be working. Then a phone (with USB charging) was plugged in, and the phone OS suspended. Removing and re-inserting the battery led to the phone (and hence battery) working, however the battery no longer charges (including with a wall charger). It seems too much to be a coincidence and am wondering what the issue may be? Ideas so far are short circuiting, or over-current to the USB ports. Note: Did not occur to me, so details are not 100% accurate or complete. Feel free to ask for missing info that I may have forgotten though.

• automatically change the gnome-terminal "title" for the window

  - by tom

  Hi. Trying to change the title of a current gnome-terminal (similar to the "set title" that you can do manually") The system is running Fedora 9. The HowTo Xterm-Title discusses how to set the prompt, for an xterm. Tried to implement the escape sequences with no luck. (might be something weird..) Tried to use the gconftool to dump/change/load the changed conf attributes, and again, no luck. Also, set the PROMPT_COMMAND just in case the prompt command was somehow changing the title back (which is highly doubtful) Searching the 'net indicates that a few people have tried to solve this with no luck... I'd also like to figure out how to create a new gnome-terminal with a unique specified title... once this is solved, i'l gladly create a quick writeup/post onn how to accomplish this for others... thanks

• Getting into the details of game engine programming

  - by Darkslash

  I am interested in learning game programming, but I really have an interest in the lower level engineering in games. I have OpenGL experience, and I am really interested in learning more about implementing AI, Physics, etc. I have a computer science degree, so I really like getting into technical stuff. Many times when I ask about this sort of thing, I get a lot of "Use an engine", "Use Unity3d", "Why waste your time writing code that already exists", etc, etc. My idea was to use simpler libraries such as SFML or XNA so that I could learn how to implement the more complex systems. The thing is, although I do want to write games, I want to learn things that using something like Unity simply doesn't teach you. My goal is not to make a current generation quality 3D game to sell, I just want to make some cool smaller games and learn all I can about the programming side of game development. Is this something that people just do not do anymore? It seems like everywhere I turn people are using Unity or UDK or GameMaker. I fully understand why you would use a tool like these, but I cant see how they would suit my purposes. So where does someone like myself turn? Am I trying to learn something that people just do not bother doing anymore? Is the innovation in this area gone and just all about gameplay now? I'm sorry if this question seems silly, but I am genuinely interested in knowing more about this and meeting more people who are interested in this sort of thing.

• Replacement for NIS/YP

  - by mdpc

  The company that I am working for is embarking on replacing the current locally developed NIS/YP structure with LDAP. We already have AD in house for the Windows stuff and would like to consider using an AD system. The AD people are quite restrictive and would not support extensive modifications. We have needs to have the replacement include the support the full capabilities of the NIS/YP suite include netgroups, login restrictions to specific servers for specific users or groups of users, consistent passwords between the *nix and Windows environment,etc. Our environment is a mixture of Linux (suse, RH, Debian), Sun, IBM, HP and MPRAS as well as a NETAPP. So whatever we use must be totally inclusive to all environment. We have looked at Likewise, but our management wants other alternatives to compare with. What other things should I be looking at and what is you assessment of the alternative? Thanks

• PHP session files have permissions of 000 - They're unusable

  - by vanced

  I kept having issues with a Document Management System I'm trying to install as, at the first step of the installation process, it would error with: Warning: Unknown: open(/tmp/sess_d39cac7f80834b2ee069d0c867ac169c, O_RDWR) failed: Permission denied (13) in Unknown on line 0 Warning: Unknown: Failed to write session data (files).

So obviously, they're unusable by PHP and it's causing me lots of problems. How can I get PHP to set the correct permissions? I've tried changing the directory which php.ini uses to /tmp/phpsessions and the same thing occurs. The directories are a+rwx.

• Best Practices PHP mvc routing

  - by dukeofweatherby

  I have a custom MVC framework that is in a constant state of evolution. There's a long standing debate with a co-worker how the routing should work. Considering the following directory structure: /core/Router.php /mvc/Controllers/{Public controllers} /mvc/Controllers/Private/{Controllers requiring valid user} /mvc/Controllers/CMS/{Controllers requiring valid user and specific roles} The question is: "Where should the current User's authentication be established: in the Router, when choosing which controller/directory to load, or in each Controller?" My argument is that when authenticating in the Router, an Error Controller is created instead of the requested Controller, informing you of your mishap; And the directory structure clearly indicates the authentication required. His argument is that a router should do routing and only routing. Leave it to the Controller to handle it on a case by case basis. This is more modular and allows more flexibility should changes need to be made by the router. PHP MVC - Custom Routing Mechanism alluded to it, but the topic was of a different nature. Alternative suggestions would be welcomed as well.

• Can a NAT close out VPN connections?

  - by Scoop

  I have a client running on a VPN behind a NAT. The client becomes inaccessible after a while if it is not "active". The VPN software is PPTP and the OS of the client if Debian. I'm unsure about the exact cause of what makes it inaccessible or if it is another piece of software that is causing the problem. But my current thing I am trying to figure out is if the NAT is healing and causing the client VPN to become inaccessible. Could this be causing the problem or should I look elsewhere?

• MS Marketing Strategy

  - by Aaron Kowall

  I found this week’s Windows Phone 8 event interesting.  Not just because it looks like some fantastic new features in the new OS but because of the wait for release.  If I were a Nokia shareholder (which I am not) I’d be very unhappy with MS announcing that Windows Phone 8 will NOT work with current hardware.  So, there are some very nice Lumia devices that are now end-of-life that have arrived relatively recently at carriers and retailers. I understand that MS needs to demonstrate progress against iOS and Android and that there is some Windows 8 tie-in that they are trying to capitalize (and MS IS still all about Windows).  However, it’s a bit of a kick to partners that have invested in the platform with pretty decent devices (Samsung, HTC and of course Nokia). Personally, I’m still using a Samsung Foucs.  I was seriously considering upgrading to a Lumia 900 (we just got Lync mobile available) but will now wait it out until new devices arrive with Windows 8.  If MS had waited to announce, I would happily have upgraded to the Lumia and when I found out it couldn’t be upgraded then that would be a gamble I took and lost and I’d live with it.  Now, however, I can see the future and know that waiting is the better option for me so that is 1 sale Nokia will miss out on.  Based on some chats I’ve seen on mobile forums I’m certainly far from the only one. I’m sure glad I’m not in charge of marketing at MS.  There are tough decisions to be made there and I’m pretty sure you piss somebody off regardless. Technorati Tags: WP8,Lumia,Nokia,Samsung

• Oracle E-Business Products New Search Helpers for Guided Resolution of Customer Issues

  - by user793044

  Oracle E-Business Proactive Support has created many new guided resolution documents that you may find helpful in resolving issues in your EBS applications.  These new documents are called “Search Helpers” and they guide you through your issue to a solution.  They are meant to be an easy and fast method to finding a relevant, complete solution. Hundreds of notes and service requests were reviewed and the best solutions to these known issues were selected.  For some issues, notes were updated to better clarify the solution.  In other cases, if a note with a solution did not already exist, one was created. You start the process by selecting the scenario you have encountered.  You may have received an error message, or there may be a particular area of the application in which you have encountered an issue.  Based on your selection of the issue, the Search Helper will present one or more additional possible symptoms.  When you have selected from both of these two sections, you are then presented with one or more articles known to have fully solved this issue in the past.  Several EBS products have produced Search Helpers documents.  Take a look at Doc ID 1501724.1 for an index of the current EBS Search Helpers.  Here is an example of a Search Helper from the Receivables Transactions area: After selecting the Functional Area of "Entering / Updating Transactions" a list of Known Symptoms is presented: And, when "Transaction numbers are not in sequence" is selected, a solution link is provided for Document ID 197212.1: How To Setup Gapless Document Sequencing in Receivables. The EBS applications that currently have published Search Helpers are: Advanced Pricing Applications Technology Configurator General Ledger Human Capital Management Inventory Management Order Management Payables Process Manufacturing Purchasing Receivables Shipping Value Chain Planning

• perform command substitution in MS-DOS

  - by wiggin200

  I wonder how you can make in MS-DOS a command substitution Command substitution is a very powerful concept of the UNIX shell. It is used to insert the output of one command into a second command. E.g. with an assignment: $ today=$(date) # starts the "date" command, captures its output $ echo "$today" Mon Jul 26 13:16:02 MEST 2004 This can also be used with other commands besides assignments: $ echo "Today is $(date +%A), it's $(date +%H:%M)" Today is Monday, it's 13:21 This calls the date command two times, the first time to print the week-day, the second time for the current time. I need to know to do that in MS-DOS, (I already know that there is a way to perform something like that using as part of the for command, but this way is much more obfuscated and convoluted

• Lynksys WRT120N wireless router not connecting to ADSL

  - by pradeetp

  I have a lynksys WRT120N wireless router that was connected to Sterlite ADSL modem. The internet connection was working fine through wireless access. I changed the ADSL router because it developed some power issues and got it replaced with the same model/brand from the service provider. However I am not able to access internet now. Here is the current setting Sterlite SAM300 XA IP Address: 192.168.2.1 (I changed it to this IP because the IP address of my ADSL router was same) Lynksys WRT120N wireless router IP Address: 192.168.1.1 If I connect my laptop to ADSL router directly, the internet works fine. It is only that that if I access it wirelessley through wireless router that I am not able to connect to internet. The IP address setting has been configured to obtain IP address automatically. I have windows 7 OS home edition. Could someone please help me to fix this issue.

• Partitions for dual boot install with Windows

  - by Tim

  Following is the layout of the current partitions of my single hard drive viewed from Windows 7: C: has Windows 7 system files and my personal data; Q: for Lenovo recovery; SYSTEM_DRV: for Windows boot files; My goals are: to create another partition D: for my personal data, and dedicate C: for Windows system files and applications only. to install Ubuntu alongside Windows. D: will be shared between the two OSes. My questions are: Is it correct that the free space generated from shrinking C: will only be able to create an extended partition, since there are already 3 primary partitions? So must D: be one logical partition on the extended partition, just as the partitions for Ubuntu will be? Will this be bad sometime? If yes, other better solutions? What are the good utilities to accomplish the partition tasks? Can Ubuntu installer solely handle them? Or better to have some of the jobs done in Windows with some recommended softwares? Thanks and regards!

• consulting a network admin for rails and php applications

  - by Karo Devos

  Hi I'm a web developer who writes most of the time rails applications. Next month I'm going to switch from my current VPS to linode. I'm wondering how much it would cost to properly set (or teach me how to do it) everything to get my app up and running. My requirements are probably: nginx/apache, REE/ruby, passenger, full blown php environment, system wide RVM, search engine such a sphinx, being able to perform cronjobs. I have some knowledge of unix and I was able to install everything I needed on my development system. However I had quite a few issues setting up everything on my production server.

• How can I see if apache is overloaded and dropping or not accepting connections?

  - by cat pants

  Basically I just want to see if apache is handling a current level of high traffic or if I need to tune it to handle more connections. (I have found plenty of information on the actual tuning, so no help needed there) I know it has been dropping or not accepting connections earlier today, but not seeing anything in the error logs. Is the expected behavior to throw a 503 in the error log if apache cannot accept more connections? If so, what error logging level do I need in order to see these? What is the correct terminology: dropping connections or not accepting connections? MPM is prefork, OS is Linux, apache version is 2.2.15.
