• Large volume at /mnt on AWS instance

  - by rhaag71

  I know this is probably a somewhat 'dumb' question :) I have an AWS (small) instance and I just noticed that there is a ~150gb volume attached at /mnt, is this normal? It kinda freaked me out, I was thinking maybe someone was trying to capture whatever I mount in /mnt, there is the entry in my fstab too (and I found that others have this by googling)... the entry is as follows /dev/xvdb /mnt auto defaults,nobootwait,comment=cloudconfig 0 2 I don't have any volumes this large in my AWS volumes section though. I was just trying to understand this and be sure that someone is not trying to 'get in'... as there are many attempts daily. Thanks

• Can I reactivate the cursor keys for modifying a cell reference in a formula?

  - by Jonas Heidelberg

  When I enter an Excel formula by hand avoiding the mouse, I can conveniently reference cells by using the arrow keys (-,<- etc.). For example, I can enter the formula =A2&B2 in cell C2 by entering =<-&<-<- The result looks like this: If I want to change from B2 to B3, I can just press the downward arrow on the keyboard at this time. How do I do the same thing later, after having left this cell (e.g. by pressing Enter)? In other words, how do I get the flashing dashed line back when re-entering a cell with F2?

• Installing VirtIO drivers in Windows Server 2008

  - by Stefan K.

  We are running a Windows Server 2008 system as a "guest" on a Linux-KVM virtual server (SLES11, with VirtIO support). We have trouble with the system performance and this is possibly due to not using the VirtIO drivers. I don't have much experience with neither KVM not VirtIO. Just heard it this could be the reason for our problem. Questions: The install examples I just found are describing how to install the drivers during Windows setup. Is it possible to install the VirtIO drivers later? We have running software on that system and would like to avoid reinstalling/setup of all these. I already found a page describing how to sign the drivers, which seems to be needed. A good tutorial page (step by step instructions) would be nice. Is there anything like that out there?

• How do I make netdiag work?

  - by Mohamed Abobakr

  I'm trying to run the netdiag command to troubleshoot the internet connection but when I run it in cmd I get the following message: 'netdiag' is not recognized as an internal or external command, operable program or batch file. Also, I have tried typing "net diag", which gives me a syntax error, but that NET command seems to be something completely different. Searching on google for answers gives me results that deal with Windows Server 2003; I'm on a Windows XP machine.

• Large mailbox in Outlook 2007 takes ages to index

  - by Reado

  In our company each user has a single mailbox and all email they have ever sent/received is in that mailbox. We don't do archiving to PST and we thought that was the way forward. The problem we now have is if someone switches to another PC for the day and opens Outlook, it has to download all emails first to that PC (cached mode) but even then when they try to search for something, Outlook says items are still being indexed. One user has over 100,000 items to be indexed and it's been saying that for about a week! As a temporary workaround I have turned off instant searching which allows them to search for anything, but it takes time to filter through, and Outlook doesn't exactly indicate if it's still searching for something, so in most cases the user thinks the search isn't working when really it is and it's just taking time to populate the results. I need a solution that allows the mailbox to be indexed really quickly if the user has to login to another PC. Are we best using Online Mode instead of Cached Mode or is there another way around this? Thanks in advance.

• Update Windows XP to SP3 without internet

  - by Alexander

  I've been asked to update some computers running Windows XP (without any service packs) to Windows XP SP3. The computers don't have an internet connection (only a small intranet) and have never been updated since first install. Do I need to install SP1a first, then SP2, then SP3, or can I install SP3 immediately? And where do I find the right files, that don't require an internet connection during installation? All help is welcome. Thanks!

  I had removed the Libraries from my Windows 7 with this registry tweaks, but since the update to Windows 8 the Liebraries are back in my Windows Explorer. So I tried to tweak the registry again, but it fails to get permission to change the value (in Windows 7 it worked). http://www.askvg.com/how-to-remove-libraries-from-windows-7-explorers-navigation-pane/ Someone know how to remove the Libraries folder or to get the permission to change the value? Here it fails to get the permission:

• Why does my CPU Usage reach 100% too often?

  - by deathlock

  I'm using a dual-core processor and often see my CPU usage reaches 100%. I realize this may happen if I'm running too much applications, so when I know the computer starts to run slowly, I start to close my applications. I usually run 4-5 applications simultaneously. Usually those are: web browser (Google Chrome), Adobe Photoshop, Notepad++, XAMPP, and Windows Task Manager. Usually I close tabs in my Chrome first, because I often browse the net with about 20 tabs/4 windows open, so I presume that would take much memory (bad habit, I know). But even after closing Chrome's tabs or closing other applications, my CPU Usage often stays at high percentage - 72% at best, 100% at worst. I check the Processes tab on Windows Task Manager and usually found the System, System Idle Process, or services.exe taking the highest CPU process (could reach 60). Why is this happening? And is there any solution? EDIT I have T2250 @ 1,73 Ghz and 2.5 GB RAM

• How do Windows 7 encrypted files look like?

  - by Sean Farrell

  Ok this is kind of an odd question: How do Windows 7 (Home Premium) encrypted files look like "from the outside"? Now here is the story. An acquaintance of a freind of mine got a nasty virus / scareware. So I wiped out my PC technician cap and went to work on it. What I did was remove the drive from the laptop and put drive into my external drive bay. I scanned the drive and yes it was loaded with stuff. That basically cured the infection and I could start the system back up. To check if it cured the problem I wanted to see the system while running. There where two user accounts, on with a password and one without (both admin users !?!). So I logged into the unprotected user and cleaned up the residual issues, like proxy server to localhost in the browser config. Now I wanted to do the same for the password protected user. What I noticed that from my system and the unprotected user account the files of the protected user looked garbled. The files are something like 12 random alphanum chars, but the folders looked ok. Naive as was thought this might be how encrypted files looked "from the outside". (I never use Microsoft's own security features, so how would I know. TrueCrypt is one big blob.) Since the second user could not be reached, I though sod it and removed the password from the account. (That might have been a mistake, I know.) Now I did the same clean up tasks and all nice and fine; except for the files which where still "encrypted". So I looked into many Windows Encrypted Files recovery posts and not all hope is lost, since I should be able to extract the certificate and with the password regain access to the files. Also note that windows did "only" prompt me that removing the password would be insecure, not that access to encrypted files would be lost, like it is claimed in most recovery articles. Resetting the password did not help and I gave up for the night. The question that nagged me half of the last night was, what if the files are not encrypted, but the scare-ware encrypted / destroyed the files? I don't want to spend hours of work trying to recover files that are not recoverable. The ting is that the user does not remember turning it on and aren't the files marked in blue and the filename is readable? Many thanks for input from users who have more knowledge about WEF...

• MS Excel and Access - which is better for reports?

  - by Nat

  Where I work, staff have just started to use a basic table in excel (1 october) to record sales which has about 10 columns (name, client, renewed, discount, paid etc). I record the data (total sold etc) every hour and email it to the manager. Each staff has the their own file on the network which they use constantly for that day (eg. John 08-10.xlsx; John 09-10.xlsx etc) and have been told to save the file after they complete a row with client data. I can see the file (in read only mode) to update the report but I am sure there must be a way of doing an autoupdate of their worksheets in real time. I can link worksheets and workbooks to my main workbook but manually. Does anyone have suggestions on have to do this on Excel? Or would Access allow me to make a report which shows the sales total for that hour without the staff closing the file or constantly clicking save every few minutes? We use office 2010. thanks

• Outlook or OWA: How can I convert an e-mail message to a draft?

  - by Beaming Mel-Bin

  There's an option in Thunderbird called Edit as new... which converts a message to a draft. I am looking for something similar in Exchange. Reasoning: We migrated old e-mail of a user from an IMAP server to Exchange. The user had many drafts saved. According to exchange though, the messages are not drafts anymore. My hunch is that, if we find a similar procedure as Thunderbird's Edit as new..., that should do the trick.

• Why won't vsftpd let me log in with a virtual user account?

  - by Ramon

  I would like to use vsftpd with virtual users and pam_pwdfile.so. I installed vsftpd and added two users (ramon and dragon) via htpasswd to my file /etc/vsftpd.passwd. The /etc/pam.d/vsftpd is configured to use this file. auth required pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed auth required pam_pwdfile.so pwdfile /etc/vsftpd.passwd account required pam_permit.so @include common-account @include common-session The user "ramon" is also available in /etc/passwd. A login to the ftp with the user "ramon" works as expected. But a login using "dragon" does not :/ The result is always Login failed: 530 Login incorrect. Since it's possible that I made a mistake I tried the exact way documented in /usr/share/doc/vsftpd/examples/VIRTUAL_USERS/README. Still no luck. I can login with the user "ramon", but not with the user "dragon". Any ideas?

• Is it possible to hide the SSID of the Windows 7 soft AP

  - by Goro

  I know it is possible to create a sofware AP in windows 7 using command prompt: netsh wlan set hostednetwork ... But is it possible to set such a network not to broadcast its SSID? I realize that this does not gain any security - or may even make the system more secure, but I am not asking about security here. I want to know if it is possible, through the netsh command interface, to hide the SSID. If my client wants to hide the SSID, then I will make them aware of security implications, but in the end it is their decision.

• Firefox s'acharne contre les plug-ins périmés et avertit plus sérieusement ses utilisateurs pour les mettre à jour

  Firefox s'acharne contre les plug-ins périmés Et avertit plus sérieusement ses utilisateurs pour les mettre à jour Les utilisateurs de Firefox risquent à l'avenir d'être harcelés par les notifications de mises à jour fréquentes des plug-ins périmés, ces sources inépuisables de problèmes de sécurité. En effet, Firefox compte appeler plus fermement à l'installation de ces mises à jour, et ce à partir de chaque page qui y fait appel, alors qu'il faut actuellement aller expressément sur le gestionnaire des extensions.

• EBS 11i and 12.1 Support Timeline Changes

  - by Steven Chan (Oracle Development)

  Two important changes to the Oracle Lifetime Support policies for Oracle E-Business Suite were announced at OpenWorld last week.  These changes affect EBS Releases 11i and 12.1. The changes are detailed in this My Oracle Support document: E-Business Suite 11.5.10 Sustaining Support Exception & 12.1 Extended Support Now to Dec. 2018 (Note 1495337.1) 1. Changes for EBS 11i Sustaining Support The first change is that  we will be providing an exception for the first 13 months of Sustaining Support on Oracle E-Business Suite Release 11.5.10 (11i10), valid from December 1, 2013 – December 31, 2014. This exception support will be comprised of three components: New fixes for Severity 1 production issues United States Form 1099 2013 year-end updates Payroll regulatory updates for the United States, Canada, United Kingdom, and Australia for fiscal years ending in 2014 Customers environments must have the minimum baseline patches (or above) for new Severity 1 production bug fixes as documented here: Patch Requirements for Extended Support of Oracle E-Business Suite Release 11.5.10 (Note 883202.1) 2. Changes for EBS 12.1 Extended Support More time:  Extended Support period for E-Business Suite Release 12.1 has been extended by nineteen months through December, 2018. Customers with an active Oracle Premier Support for Software contract will automatically be entitled to Extended Support for E-Business Suite 12.1. Fees waived:  Uplift fees are waived for all years of Extended Support (June, 2014 – December. 2018) for customers with an active Oracle Premier Support for Software contract. During this period, customers will receive all of the components of Extended Support at no additional cost other than their fees for Software Update License & Support. Where can I learn more? There are two interlocking policies that affect the E-Business Suite:  Oracle's Lifetime Support policies for each EBS release (timelines which were updated by this announcement), and the Error Correction Support policies (which state the minimum baselines for new patches). For more information about how these policies interact, see: Understanding Support Windows for E-Business Suite Releases What about E-Business Suite technology stack components?Things get more complicated when one considers individual techstack components such as Oracle Forms or the Oracle Database.  To learn more about the interlocking EBS+techstack component support windows, see these two articles: On Apps Tier Patching and Support: A Primer for E-Business Suite Users On Database Patching and Support: A Primer for E-Business Suite Users Related Articles Extended Support Fees Waived for E-Business Suite 11i and 12.0 EBS 12.0 Minimum Requirements for Extended Support Finalized

• What to choose API based server or Socket based server for data driven application

  - by Imdad

  I am working on a project which has a Desktop Application for MAC/COCOA, a native application for iPhone another native application in iPad. All the application do almost same thing. The applications are data driven applications. Every communication to server is made via a restful API developed in PHP. When a user logs in a lot of data is fetched from server. And to remain in sync with server pooling is done. As there are lot of data to pool it makes application slower and un-reliable. A possible solution that comes into my mind is to use Socket based server. My question is that will it reasonably improve the performance? And which technology (of sockets) will be good as a server side solution for data driven application? I have heard a lot about Node.js. Please give your suggestions.

• Lua & Javascript documentation generation

  - by Tiddo

  I am in the beginning phase of create a mobile MMO with my team. The server software will be written in JavaScript using NodeJS, and the client software in Lua using Corona. We need a tool to auto-generate documentation for both the server-side and client-side code. Are there any tools which can generate documentation for both Lua and Javascript? And as a bonus: we are hosting our project on Bitbucket and the Bitbucket Wiki uses the Creole markup language. So if it's possible I want the tool to export to Creole.

• Questions about linking libraries in C

  - by james

  I am learning C (still very much a beginner) on Linux using the GCC compiler. I have noticed that some libraries, such as the library used with the math.h header, need to be linked in manually when included. I have been linking in the libraries using various flags of the form -l[library-name], such as -lm for the above-mentioned math library. However, after switching from the command line and/or Geany to Code::Blocks, I noticed that Code::Blocks uses g++ to compile the programs instead of the gcc that I am used to (even though the project is definitely specified as C). Also, Code::Blocks does not require the libraries to be manually linked in when compiling - libraries such as the math library just work. I have two questions: Firstly, is it "bad" to compile C programs with the g++ compiler? So far it seems to work, but after all, C++ is not C and I am quite sure that the g++ compiler is meant for C++. Secondly, is it the g++ compiler that is doing the automatic linking of the libraries in Code::Blocks?

• Is it a bug or a task when something doesn't work, yet, in development process

  - by Patkos Csaba

  We usually have this dilemma in our team. Sometimes, in order to implement a task or a story we find out that the system must be in a specific state. For example, a specific system configuration has to be made beforehand. The task / story can be completed and it is working as specified on it with the proper configuration in place. Note that the configuration is not directly related with the task. Next, we have to create a new ... ??? ... something for the process of generating that configuration file. This is where the problems appear. Some say that it is a bug others say it is a task or an extra feature. So, where is the limit between bugs and tasks in the development phase? Should we even consider something a bug if all the tasks are working as stated in their definitions? Can a thing be considered a bug because one compares it to the current (unstable) state of the system? Short example: A feature requires configuring a communication service for a specific operation. In the process of the implementation the team discovers that the service requires the hostnames of the pears to be resolvable to an IP address. The team adds the hostnames to the DNS server (or hosts files) and continues implementing the required feature. After the initial feature is working, a question is risen. Should the sysadmin configure the DNS or hosts file or should our application do it automatically? An automatic solution is possible. So a decision is made to implement it. ... here start the discussions ... is this a bug or an extra feature / task? PS: I know that I mixed feature / task / story in the question. It is intentional. I am interested in separating bugs from the rest. Doesn't matter what the rest means in a particular case.

• Why has extreme programming (XP) gone out of date in favor of Agile, Kanban etc?

  - by Nick Rosencrantz

  I like XP (extreme programming) especially the part where there are 2 programmers at the same screen since often a problem's solution gets closer if only you explain what you're doing and pair programming forces you to explain what your doing. Last 10 years or so, the XP style of working seems to have gone out of date in favor of the working methodologies Agile and/or Kanban. Why? Since XP to me seems a veru good way to work and is a lot about the programming where Agile and Kanban are more about processes.

• Text Classification Implementation

  I've been trying to implement a text classification system. It needs to read a text file, and extract the words and the word frequency. So far, I've been planning to parse the words, put them in a dictionary and save it to an XML file. I am using C++/CLI. Is this a good implementation or is there a simpler or better implementation?

• ZTE USB Modem AC2736, connection not possible in Ubuntu 12.04.1 LTS

  - by Fredo

  It's a long post but nearly covers all my experiments and changes I did to my NM. Hope the information is complete and if there are still question, more information can be provided. I've a ZTE AC2736 USB Modem (CDMA modem) which worked fine in Ubuntu 10.04 /11.10. I recently switched to 12.04.1 (precise pangolin). after the switch the first issue I faced was to connect to internet using my USB modem (ISP: Reliance Brand: Netconnect). Tried to run the drivers provided by Reliance but they are old and won't support Kernel 2.6.30 above. since the code was not downloaded with ISO image (of 12.04) i couldn't compile the files provided in such driver. lsusb does detect it as Modem with output similar to 19d2:fff1 ZTE CDMA technologies inc. (or similar as i didn't note it down) If it is detected as USB storage it shows 19d2:fff5 (as per few online forums, i may be wrong here). I used the network Manager and configured the modem to dial #777 (default) and the ISP provided username:password combination. It tries to connect to internet (3-4 times automatically)but fails to get online. once I was able to connect in the monring hours and the message was flashed 'registered on CDMA home network'. I was able to run an update. the kernel was updated with 3.0.2 -pae OR something similar (can find out if required). I surfed the net for about 2 hours later before restarting. After the restart, again the Modem was not able to get me online. I kept trying for many times. I tried changing the setting in NM. One evening after dark I was able to connect to network with same message flash 'registered on CDMA home network' (the message was similar, i'm not precise here,sorry). I was able to surf the net for nearly 3 hours before I switched off my Laptop. I'm not able to get online after that day, It's been 3 days now. I'll try the observered theory of late/early hours sometime soon as mentioned below. Laptop configuration : Make: Lenovo Model: B480 Processor: Intel B950 RAM: 4G DDR3 HDD: 500 G Broadcom Wireless/Bluetooth/Ethernet LAN OS: FreeDOS / Ubuntu 12.04 LTS (dualboot) Kernel 3.0.2-pae Obeservation : I'm able to connect to internet in those hours when generally the speed is high (low usage by other network (wireless) users). like in early mornings or late nights. This is strange as connection should not be dependent on bandwidth usage. Any help would be appraciated to fix this issue. before I decide to cahnge the OS or ISP.
