• MS Access ADP front end and SQL Server back end for field data collection?

  - by Brash Equilibrium

  I am an anthropologist. I am going to the field and will use a netbook to collect survey data. The survey forms will need to allow me to enter data into multiple tables, search tables, allow subforms, and be fast enough to not slow down my interview. I have considered storing the data in a SQL Server Express 2008 R2 server (there will be a lot of data) while using a Microsoft Access data project as a front end. To cut down the number of steps required to collect and store data, I'm considering using the netbook for both data storage and collection (after reading this article about SQL Server on a netbook). My questions are: (1) Is there a simpler solution that is also gratis (gratis because I already have a MS Access license from my workplace, and SQL Server Express is, obviously, free)? (2) Does my idea to store and collect data using the netbook make sense? Thank you.

• Limit number of concurrent user logins in Windows Server 2008 Active Directory

  - by smhnaji

  Is there the possibility to limit Active Directory users' max concurrent login sessions? I've read many articles and discussions about the solution, but none of them seem to be working. Many had suggested UserLogin script that doesn't work in Windows Server 2008. Some other suggested CConnect that is not good enough. It's also very complicated. Some others have introduced UserLock that should be paid for. It's wondering that Windows Server 2003 DOES have the feature (wile as a third-party), but Windows Server 2008 doesn't have! One of the articles I've read: http://www.edugeek.net/forums/windows-server-2008-r2/61216-multiple-logins.html

• formatting a column based on another columns cell TEXT not value in excel

  - by lisa

  I have dates that are running off a formula in that column based on information it is collecting from other worksheets. I have another column that lists text answers based on a different formula that that column is running. It is a customer list that runs with names going down page and multiple columns of information for each client running across page What i want to do is: If column j says "paid" then turn column m - same row - a color or border or something I will repeat this formula for the various things that j can say, just cant figure out how to make conditional formatting read j to change m. To complicate things, in addition to the formula running to collect the date in m, there is also a conditional format set up for m that changes the color of the cells after a certain date. I want to be able to keep that formula, in addition to the one that you are assisting with...i will use highlighting, or something different to avoid any conflicts.

• Windows equivalent for Linux "screen" or another alternative?

  - by Ubha

  Hello all! I'm on the lookout for a method to control programs in a Windows environment. I would prefer it to be a bit similar to the Linux software "screen". The reason of my search is that I need to start a program (on Windows) with an identifier, so I later would be able to close that specific program, without closing anything else - even though the actual program (.exe file) is running multiple times. So is there anyway I can "name" it? I'm using the following on Linux now: $ screen <params> <id> ./softwareprogram And then I know I can always find it with it's ID :) It's an external program which is closing or starting a 3rd party program. My program is written in C++, if that does any difference. Thanks :)

• What to do with old hard drives?

  - by caliban

  I have over 100+ old hard drives, ranging from 100MB Quantums to 200GB WDs, most of them PATA, some SATA. Most still working. The squirrel mentality runs in my family - hoard everything, discard nothing. Thus, and this is a relevant question - any suggestions on how to put these drives to use (anything) instead of them just being deadweights and space takers around the office? Hopeful objectives and suggestions to keep in mind when you post an answer : Should showcase your geekiness, or plain fun, or serve a social purpose, or benefit the community. You do not need to limit your answer to only one hard drive - if your project needs all 100++, bring it on! Your answer need not be limited to one project per hard drive - if one hard drive can be used for multiple projects, bring it on! If additional accessories need be purchased, make sure they are common. Don't tell me to get a moon rock or something. The projects you suggested should serve a utility, and not just for decoration purposes.

• Problem connecting with RDP between Mac and Win2k3 server

  - by salle55

  I have an iMac running Mac OS X 10.5.8 and the RDP Connection Client 2.0.1. http://salle.dyndns.org/misc/rdp%5Fproblem1.png When I try to connect to a Windows 2003 Server on the same network I get a dialog saying "Remote Desktop Connection cannot verify the identity of the computer that you want to connect to". Picture: salle.dyndns.org/misc/rdp_problem2.png And when I press the Connect-button in the previous dialog I get the same message in another dialog: Picture: salle.dyndns.org/misc/rdp_problem3.png I can connect to the Win2k3 server from a Vista machine, and it used to work from the Mac as well. I stopped working from the Mac after I did some configuration on the win2k3 server, removed and added the the connection in the Terminal Services Configuration: Picture: salle.dyndns.org/misc/rdp_problem4.png What do I need to do to be able to connect from the Mac again?

• Disable Control-L hotkey on YouTube

  - by Heptite

  I am used to using Ctrll to access my address bar. Unfortunately YouTube "helpfully" defines Ctrll as a hotkey to jump forward several seconds in the currently playing video, so I need a way to stop YouTube from adding that key binding. A Greasemonkey/Scriptish userscript that disables the binding after page load would be acceptable. To be clear, this is while I am on a YouTube video's page, not on a third-party site that has embedded a YouTube video, and the behavior occurs when the Flash player does not have focus. Note: I am aware that Altd does the same as Ctrll in Firefox, but I'm too used to Ctrll and I'd rather not be forced to switch. Edit: OS-specific solutions are less desirable since I use multiple OSes; in-browser solutions are preferred.

• Blackberry keeps sending notifications of FB and emails [closed]

  - by tfalise

  Here is the problem I got with my blackberry : I have received and sent multiple mails this week-end from my home computer. As usual, I received the notifications of sent and received emails on my blackberry, and archived / deleted them. But, I still receive the notifications of new mails several times a day, for emails I already have deleted in my Gmail account. I tried rebooting the blackberry (alt+shift+del) and removing the battery, but nothing helps, the notifications are sent and re-sent, no matter what I do. Anyone has an advice on how to stop this spam, as it is becoming very annoying ?

• Designing communications for extensibility

  - by Thomas S.

  I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

• Is it possible to live-boot VirtualBox from a USB flash drive?

  - by bw.

  To clarify, I'm not asking if you can boot from USB from within VirtualBox. I would like to make a portable version of Windows 7 that I can run from a USB drive on any machine. I'm putting a distro of Linux on my laptop, but I manage a Windows domain at work so I'd like an easier management solution than trying to use Linux tools to interface with a Windows DC(as RDP to a DC is not always an option). The reason I'm inquiring about VirtualBox... I plan on carrying this portable installation with me and using it on multiple machines, so I would like to avoid driver conflicts (which I imagine would happen if I only installed Windows on a flash drive). Basically, I need a way to boot an installation of Windows 7 from USB that still allows me to install/remove/update programs as if it were installed on a standard hard drive, and not freak out over different hardware configurations. Please help, superusers!

• How to build an API on top of an existing Rails app with NodeJs and what architecture to use?

  - by javiayala

  The explanation I was recently hired by a company that has an old RoR 2.3 application with more than 100k users, a strong SEO strategy with more than 170k indexed urls, native android and ios applications and other custom-made mobile and web applications that rely on a not so good API from the same RoR app. They recently merged with a company from another country as an strategy to grow the business and the profit. They have almost the same stats, a similar strategy and mobile apps. We have just decided that we need to merge the data from both companies and to start a new app from scratch since the RoR app is to old and heavily patched and the app from the other company was built with a custom PHP framework without any documentation. The only good news is that both databases are in MySQL and have a similar structure. The challenge I need to build a new version that: can handle a lot of traffic, preserves the SEO strategies of both companies, serve 2 different domains, and have a strong API that can support legacy mobile apps from both companies and be ready for a new set of native apps. I want to use RoR 3.2 for the main web apps and NodeJs with a Restful API. I know that I need to be very careful with the mobile apps and handle multiple versions of the API. I also think that I need to create a service that can handle a lot IO request since the apps is heavily used to create orders for restaurants at a certain time of the day. The questions With all this in mind: What type of architecture do you recommend me to follow? What gems or node packages do you think will work the best? How do I build a new rails app and keep using the same database structure? Should I use NodeJS to build an API or just build a new service with Ruby? I know that I'm asking to much from you guys, but please help me by answering any topic that you can or by pointing me on the right direction. All your comments and feedback will be extremely appreciated! Thanks!

• Ways to setup a ZFS pool on a device without possibility to create/manage partitions?

  - by Karl Richter

  I have a NAS where I don't have a possibility to create and manage partitions (maybe I could with some hacks that I don't want to make). What ways to setup multiple ZFS pools with one partition each (for starters - just want to use deduplication) exist? The setup should work with the NAS, i.e. over network (I'd mount the images via NFS or cifs). My ideas and associated issues so far: sparse files mounted over loop device (specifying sparse file directly as ZFS vdev doesn't work, see Can I choose a sparse file as vdev for a zfs pool?): problem that the name/number of the assigned loop device is anything but constant, not sure how increasing the number loop device with kernel parameter affects performance (there has to be a reason to limit it to 8 in the default value, right?)

• Radeon hd 5700 monitor blank until connected HDMI device is started

  - by kaido loor

  Have win7, radeon hd 5700. When both PC monitor and HDMI device (Onkyo 607) are connected to Radeon card, the monitor diplays boot info, "starting windows, etc" but goes blank when "log into windows" should appear. Monitor comes back (w normal screen) if Onkyo and TV are turned on, not before. Multiple monitors is disabled. Really crazy. Any help appreciated. Generally, Onkyo can pick up HDMI signal ok, so at least smth works as intended.

• Sharing / replicating EBS across AWS nodes

  - by skrat

  I would like to use single EBS storage across multiple EC2 nodes (web/app servers). I've read some articles on snapshot sharing, but that doesn't suit well for what we need. We use filesystem for storing DB record attachments, so if one such attachment gets created, we need it to be immediately available to all nodes (to serve). So far only NFS seem to be viable, but it's a pain to configure and maintain. Another option could be storing those attachments on S3 instead, but that would cut us of doing any analysis on that data. This must be quite common problem when scaling in AWS, what solutions are there?

• How can I set up an FTP user with a home directory inside another user's home folder?

  - by simon180

  Hi I have an Ubuntu (Hardy) server which I am using to host multiple websites. All of the sites are stored in subfolders of a public_html folder for my main login to the server and accessed via a single SSH account. I now have a website user who wants FTP (or similar) access to enable them to upload various files etc to the directory where their website is situated, however I still need the SSH account to have access to this directory as I may need to make changes using my master account. Basically I want to create an FTP account (I have VSFTPD installed) for a user with the home directory inside my own user account but they should only be able to read/write to this folder or its subfolders but not go further up the directory tree. How can I achieve this? Thanks

• Prevent Windows Exporer to extract metadata

  - by olafure

  Windows Explorer (windows 7 x64) crashes when it sees allegedly corrupted .wav files. I'm dealing with this problem and the hotfix doesn't work for me: http://support.microsoft.com/kb/976417/en-us The hotfix says that this happens if the .wav file is corrupt (which btw I don't think it is). What makes this even worse is that I can't access the file in any program! As soon as the open dialog sees the file, windows tries it's metadata extraction trick and exporer.exe halts. So my question: Can I by any means tell windows to stop this "metadata extraction" action ? (I have seen multiple problems associated with it in the past).

• Setup IPv4 local on IPv6 VPS

  - by A.D.

  I have a dedicated server running multiple IPv6 only OpenVZ containers. I want them to be able to communicate with the IPv4 internet, but I realized that isn't going to be possible with IPv6 only. So they need to have an IPv4 address as well, not sure if a local address will work for it, but pretty sure it should. I added 169.254.1.100 in the container .conf file, but when I try to start it, I get this : Adding IP address(es): (the IPv6 address) 169.254.1.100 arpsend: 169.254.1.100 is detected on another computer : 00:04:9b:f2:b0:00 vps-net_add WARNING: arpsend -c 1 -w 1 -D -e 169.254.1.100 eth0 FAILED I did a lot of research, and searched serverfault before posting this, but found nothing relating to this.

• Moving Mail between Exchange Mail Queues

  - by Eli

  We have multiple Microsoft Exchange 2007 nodes and 2 Exchange hubs. One of our users unfortunately had their account compromised, which then sent out several thousand emails before we were able to stop them. During this time, however, several primary mail providers blocked one of our Exchange hubs as a spam source. We now have nearly 500 messages built up on the one hub server waiting to go out to a provider who is currently blocking that hub. I know it is possible to change the location of the mailqueue and I could copy the queue database over from one hub to another and than change the location the HUB is looking at to a different file - let the mail spool out and then change the location back, but I would like a cleaner solution. Therefore, the question: is there a way to quickly and easily move messages from one Exchange hub server to another Exchange hub server?

• Why job postings always looking for "rockstars?" [closed]

  - by Xepoch

  I have noticed a recent trend in requesting programmers who are rockstars. I get it, they're looking for someone who is really good at what they do. But why (pray) make the reference to a rockstar? Do these companies really want these traits as a real rockstar? Party all night and wake up to take care of quick business in the morning? Substance abuse, Narcissism with celebrity, Compensation well exceeding their management, Excellent at putting on a short-lived show, Entertainment instead of value, 1 hit (project) wonders or single-genre performers, Et cetera What is wrong with Senior or Principal Software Engineer who has an established and proven passion for the business? Rather do we mean quite the opposite, someone who: rolls up the sleeves and gets to work, takes appropriate direction and helps influence teams, programs in lessons' learned and proper practices, provides timely communication to the whole team, can code and understand multiple languages, understands the science and theory behind computation, Is there a trend to diversify the software engineering ranks? How many software rockstars can you hire before your band starts breaking up? Sure, there are lots of folks doing this stuff on their own, maybe even a rare few who do coding for show, but I wager the majority is for business. I don't see ads for rockstar accountants, or rockstar machinists, or rockstart CFOs. What makes the software programmer and their hiring departments lean towards this kind of job title?

• Windows xp - recover document opened directly from IE

  - by Thingfish

  Hi Attempting to help a family member recover a document. The word 2007 document was downloaded and opened directly from a webmail interface using Internet Explorer running on Windows XP. The user saved the document multiple times while working on it for the good part of a day. After closing Word 2007 the user is not able to locate the document, and I have so far not been able to help. The computer has not been turned off, and the user has not attempted to open the document directly from the mail again. Recreating the events on vista/windows 7 its easy enough to locate the document under the Temporary Internet Files folder. I have however not been able to do the same on a Windows XP. Any suggestion for how to locate this document, or if its even possible? Thanks

• Storing images in file system and returning URLs or virtually resizing and returning byte arrays?

  - by ismaelf

  I need to create a REST web service to manage user submitted images and displaying them all in a website. There are multiple websites that are going to use this service to manage and display images. The requirements are to have 5 pre-defined image sizes available. The 2 options I see are the following: The web service will create the 5 images, store them in the file system and and store the URL's in the database when the user submits the image. When the image is requested, the web service will return an array of URLs. I see this option to be a little hard on the hard drive. The estimates are 10,000 users per site, and lets say, 100 sites. The heavy processing will be done when the user submits the image and each image is going to be pulled from the File System. The web service will store just the image that the user submits in the file system and it's URL in the database. When the user request images, the web service will get the info from the DB, load the image on memory, create its 5 instances and return an object with 5 image arrays (I will probably cache the arrays). This option is harder on the processor and memory. The heavy processing will be done when the images get requested. A plus I see for option 2 is that it will give me the option to rewrite the URL of the image and make them site dependent (prettier) than having a image repository for all websites. But this is not a big deal. What do you think of these options? Do you have any other suggestions?

• Problem Updating/Installing Java

  - by Click Upvote

  I've had Java installed on my computer for a while. However lately, whenever I go to a website which has got a java applet in it, i only see a white box where the applet previously used to run (this is happening on multiple sites, not just one). I figured I might have to download java again, so I went to this page and downloaded the installer. However, each time the installer finishes downloading whatever it needs to, I get the error: 'Unable to uncompress java installer' (or perhaps its 'Unable to uncompress downloaded files'. What shall I do? I'm using Windows XP, and I'm still able to run Netbeans on the computer, the problem seems to only be with applets, and occurs in all browsers.

• Error code 2503 - Cannot install software on Windows 7 (64Bit)

  - by SixfootJames

  A short while ago, I had my hard drive die on me and at the same time my 1Tb backup drive! I took it back to the guy I bought the PC from and although the backup drive could not be recovered, he managed to get my machine working again by making a minor change in the BIOS which then got it out of that continuous loop it found itself in after multiple BSOD episodes. Everything seems to be working fine but yesterday when I tried to save something from Google Chrome, I got and insufficient permission problem and when I try to install software, I get an error of 2503. I have already followed the suggestions here but none of this worked for me. Any suggestions would be appreciated. EDIT: This started happening after I tried running a number of tests to get the machine working, including a previous restore point.

• Raid-3 like software backup tool

  - by Chronial

  I have a lot of data (about 7 TB), stored across multiple hard-drives with varying sizes. I would like to have a backup of that data to be safe against drive failure. A RAID is not a good option for me, as I want to keep my cost low and be able to easily extend the storage capacity of my setup by buying an additional HD. I remember seeing a piece of software that generates parity data over all drives and stores that on an extra drive. That solution protects the setup from hard drive failure and works with varying drive sizes (as long as the parity drive is the biggest one). But I can’t seem to find that software again. Does anybody now what I’m talking about or have any other solution for my situation?
