How to run installation CD for second monitor?

- by dobsoft

I am running ubuntu 14 off of a live USB. I have a second monitor that I would like to use while using ubuntu. It has an installation cd that you have to install before using, and when I click on the .exe file the Archive Manager tries to open it and says an error occurred while loading the archive. Thanks for the help. Edit: additional information It just doesn't show up when when I'm in the display settings area. I press the locate(name is probably something else) monitor button too. I know it needs the CD because when I was using it with Windows it didn't work until I went through the installation process on the CD. If ubuntu doesn't use .exe files is there a way to use the CD still? Monitor info from label: -acer LCD monitor -model number: S200HQL Version: S200HQL bd I connect it to my computer using a VGA cord which is connected to a j5create VGA to USB adapter.

Session state provider and atomic operations

- by vtortola

Hi, I've been thinking about this and it is blowing my mind... How does a session state provider properly works internally? I mean, I tried to write a custom session state provider based on Azure Tables or Blobs, but quickly I realized that because there is no way to ensure an atomic operation or establish a lock, race conditions are suitable to happen when several web servers do operation on that shared information. I know that there is a SQL Server Session State Provider (SQLS-SSP) and people is happy with it, so I guess that it's using some kind of transaction isolation level in order to accomplish some degree of concurrent safety, like checking is the data is lock (a simple column), locking it if not and returning the data in an atomic operation, but is that so? what does happen if the data is lock? does it returns an error? block the call for a while? returns it in read-only fashion? Cloud computing paradigms could be somehow new, but webfarms have been here for a while, so as I'm pretty new on it... do you recommend any good lecture about the topic? Thanks.

Sync Google Contacts with QuickBooks

- by dataintegration

The RSSBus ADO.NET Providers offer an easy way to integrate with different data sources. In this article, we include a fully functional application that can be used to synchronize contacts between Google and QuickBooks. Like our QuickBooks ADO.NET Provider, the included application supports both the desktop versions of QuickBooks and QuickBooks Online Edition. Getting the Contacts Step 1: Google accounts include a number of contacts. To obtain a list of a user's Google Contacts, issue a query to the Contacts table. For example: SELECT * FROM Contacts. Step 2: QuickBooks stores contact information in multiple tables. Depending on your use case, you may want to synchronize your Google Contacts with QuickBooks Customers, Employees, Vendors, or a combination of the three. To get data from a specific table, issue a SELECT query to that table. For example: SELECT * FROM Customers Step 3: Retrieving all results from QuickBooks may take some time, depending on the size of your company file. To narrow your results, you may want to use a filter by including a WHERE clause in your query. For example: SELECT * FROM Customers WHERE (Name LIKE '%James%') AND IncludeJobs = 'FALSE' Synchronizing the Contacts Synchronizing the contacts is a simple process. Once the contacts from Google and the customers from QuickBooks are available, they can be compared and synchronized based on user preference. The sample application does this based on user input, but it is easy to create one that does the synchronization automatically. The INSERT, UPDATE, and DELETE statements available in both data providers makes it easy to create, update, or delete contacts in either data source as needed. Pre-Built Demo Application The executable for the demo application can be downloaded here. Note that this demo is built using BETA builds of the ADO.NET Provider for Google V2 and ADO.NET Provider for QuickBooks V3, and will expire in 2013. Source Code You can download the full source of the demo application here. You will need the Google ADO.NET Data Provider V2 and the QuickBooks ADO.NET Data Provider V3, which can be obtained here.

fsck: FILE SYSTEM WAS MODIFIED after each check with -c, why?

- by Chris

Hi I use a script to partition and format CF cards (connected with a USB card writer) in an automated way. After the main process I check the card again with fsck. To check bad blocks I also tried the '-c' switch, but I always get a return value != 0 and the message "FILE SYSTEM WAS MODIFIED" (see below). I get the same result when checking the very same drive several times... Does anyone know why a) the file system is modified at all and b) why this seems to happen every time I check and not only in case of an error (like bad blocks)? Here's the output: linux-box# fsck.ext3 -c /dev/sdx1 e2fsck 1.40.2 (12-Jul-2007) Checking for bad blocks (read-only test): done Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information Volume (/dev/sdx1): ***** FILE SYSTEM WAS MODIFIED ***** Volume (/dev/sdx1): 5132/245760 files (1.2% non-contiguous), 178910/1959896 blocks Thanks, Chris

Nginx or Apache for a VPS?

- by James

I consider myself to be an inexperienced user/administrator when it comes to running my VPS. I can get by with a few CLI commands, I can set up Webmin and I can set up Yum repos, but beyond the very basic stuff, I'm out of my depth. So far, I'm running Apache. I don't know it particularly well, but I can get by with editing httpd.conf if I'm told what to edit. I've heard good things about Nginx and that it's not as resource-hungry as Apache. I'd like to give it a go, but I can't find any information about its suitability for administrators like me, with little experience of sysadmin or web server config. Webmin now has support for Nginx, so getting it installed and running probably won't be too much of a problem. What I'm wondering is, from a site administrator perspective, is running Nginx as transparent as running Apache? IE, at the moment, I can just throw up Wordpress and Drupal sites without having much to worry about or having to make any config changes to Apache. Would Nginx be as transparent?

Google Glasses–A new world in front of your eyes

- by Gopinath

Google is getting into a whole new business that would help us to see the world in a new dimension and free us from all gadgets we carry we today. Google Glasses is a wearable tiny computer that brings information in front of your eyes and lets you interact with it using voice commands. It’s a kind of glasses(spectacles) that you can wear to see and interact with the world in a new way. With Google Glasses, for example you can look at a beautiful location and through voice you can instruct it to capture a photograph and share it to your friends. You don’t need a camera to capture the beautiful scene, you don’t need an App to upload and share it. All you need is just Google Glasses By the way these glasses are not heavy head mountable stuff, they are very tiny one and look beautiful too. Check out the embedded video demo released by Google to see them in action and for sure you are going to be amazed. Last year December 9 to 5 Google posted details about this secret project and NY Times says that these glasses would be available to everyone at affordable cost, anywhere between $250 and $600. It is powered by Android OS and the contains a GPS, motion sensor, camera, voice input & output devices. Check out Project Glass for more details.

Archive Recorded Show from DVR

- by BillN

IF I have an AT&T U-Verse DVR, is there a way to copy the information off the DVR to an PC for Archiving/burning to a DVD? I know that I could connect the A/V outs on the DVR to the A/V inputs on a DVD Recorder, or to a capture card on a PC, and Play the show, and record in real-time on the DVD or PC, but if the show is say a World Cup Game, this would take 2-3 hours per. My thought is that the DVR is just a HardDrive, and the files have to be stored in an digital format, it should be possible to do a copy of some sort. I'm currently recording all of the WC games, but if I don't watch them right away, I'm concerned that I will push other programming that the rest of the family has recorded out, making me unpopular at home. Note, I'm talking about archiving for personal use, not redistribution or anything.

Error with APE Server Installation

- by sadmicrowave

I was trying to install APE-Server from the .deb file at the ape-server homepage (www.ape-project.org) and I ran into an error so wanted to try removing the installation and reinstalling. I did a sudo apt-get remove ape-server which ran successfully but left ape-server folders in my /etc/ and /etc/init.d locations. Me being an idiot new comer to linux decided that manually delete those folders. Now when I reinstall the ape-server those folders don't get recreated and therefore I cannot send the /etc/init.d/ape-server [option] command because the folder is not found. When I try to sudo apt-get purge (or remove) ape-server I get the following sudo apt-get purge ape-server Reading package lists... Done Building dependency tree Reading state information...

What characteristic of a software determines its operational scope?

- by Dark Star1

How can I classify whether a software is a medium with the ability to grow into an enterprise level software or whether it is already there? And how should I use the information to choose the appropriate language/tool to create the software? At first I was asking whether Java or PHP is the best tool to design enterprise level software, however I've suddenly realized that I am unable to put the software I'm tasked with redesigning into the proper scope so I'm lost. Edit: I guess I'm looking for tell tale signs in software that may tip the favour towards enterprise level type software in the sense of functional and operational characteristics; functional: what it does (multi-functional), Architectural characteristics such as highly modular. operational: multi-sourced and multi-homed, databases, e.t.c. To be honest the reason I ask is because I'm skeptical about the use of PhP to design a piece of employee and partial accounting software. I'm more tipping towards the use of JSP and an hmvc framework such as JSF, wickets, e.t.c. where as the other guy wants to go the PhP way although I'm not experienced with PhP, as far as I know it's not an OO oriented language hence my skepticsm towards it.

DNS A vs NS record

- by Tiddo

I'm trying to understand DNS a bit better, but I still don't get A and NS records completely. As far as I understood, the A record tells which IP-address belongs to a (sub) domain, so far it was still clear to me. But as I understood, the NS record tells which nameserver points belongs to a (sub) domain, and that nameserver should tell which IP-address belongs to a (sub) domain. But that was already specified in the A record in the same DNS file. So can someone explain to me what the NS records and nameservers exactly do, because probably I understood something wrong. edit: As I understand you correctly, a NS record tells you were to find the DNS server with the A record for a certain domain, and the A record tells you which ip-address belongs to a domain. But what is the use of putting an A and an NS record in the same DNS file? If there is already an A record for a certain domain, then why do you need to point to another DNS server, which would probably give you the same information?

What is the best approach for inline code comments?

- by d1egoaz

We are doing some refactoring to a 20 years old legacy codebase, and I'm having a discussion with my colleague about the comments format in the code (plsql, java). There is no a default format for comments, but in most cases people do something like this in the comment: // date (year, year-month, yyyy-mm-dd, dd/mm/yyyy), (author id, author name, author nickname) and comment the proposed format for future and past comments that I want is: // {yyyy-mm-dd}, unique_author_company_id, comment My colleague says that we only need the comment, and must reformat all past and future comments to this format: // comment My arguments: I say for maintenance reasons, it's important to know when and who did a change (even this information is in the SCM). The code is living, and for that reason has a history. Because without the change dates it's impossible to know when a change was introduced without open the SCM tool and search in the long object history. because the author is very important, a change of authors is more credible than a change of authory Agility reasons, no need to open and navigate through the SCM tool people would be more afraid to change something that someone did 15 years ago, than something that was recently created or changed. etc. My colleague's arguments: The history is in the SCM Developers must not be aware of the history of the code directly in the code Packages gets 15k lines long and unstructured comments make these packages harder to understand What do you think is the best approach? Or do you have a better approach to solve this problem?

When and why you should use void (instead of i.e. bool/int)

I mean, when looking at the code, it apparently works just as nice as a void and after a moment of thought, I ask "Why?" Does this sound familiar? Sometimes I would agree that most often it is better to return something like a bool or int, rather then just do a void. I'm not sure though, in the big picture, about the pros and cons. Depending on situation, returning an int can make the caller aware of the amount of rows or objects affected by the method (e.g., 5 records saved to MSSQL). If a method like "InsertSomething" returns a boolean, I can have the method designed to return true if success, else false. The caller can choose to act or not on that information. On the other hand, May it lead to a less clear purpose of a method call? Bad coding often forces me to double-check the method content. If it returns something, it tells you that the method is of a type you have to do something with the returned result. Another issue would be, if the method implementation is unknown to you, what did the developer decide to return that isn't function critical? Of course you can comment it. The return value has to be processed, when the processing could be ended at the closing bracket of method. What happens under the hood? Did the called method get false because of a thrown error? Or did it return false due to the evaluated result? What are your experiences with this? How would you act on this?

Developing an internet-enabled application as a Kiosk on Windows 7

- by maple_shaft

I am finalizing development of a desktop Java application that communicates with an outside web server, and now I need to start seriously considering deployment. This application will run on a large touchscreen all-in-one workstation running Windows 7. It will be located in a public-area and thus must be LOCKED-DOWN Hanibal Lecter style. Early in the project nobody really concerned themselves with this fact just assuming that we can buy some magical software for Windows 7 that will automatically take care of all this, however I am finding now that this looks to be a LOT more complicated than my manager ever thought. I need to: - Lock down the standard hot-keys (ALT+TAB, ALT+CTRL+DEL, etc...) Prevent the user from opening ANY programs other than the kiosk application and its spawned executables Prevent the user from closing the application Start the kiosk application on startup (this can be done without kiosk software) Auto-login to Windows on reboot (Windows Updates, power failure, bratty kid pressing the power button, etc...) Administrator passcode escape sequence for routine maintenance by desktop support professionals. To my dismay I am having a really hard time finding software that contains the whole package and am finding numerous swaths of competing information on the best way to do this. I am not necessarily looking for free or open source software and am willing to pay for software that can help me achieve this. Have any of you ever wrote kiosk software before and if so what approaches have you taken to do this?
