• Simple command line calculator

  - by ldigas

  Had one years ago (on Win 3.1 or '95, I'm not sure). Anyways, it was a really simple program. Stood somewhere in PATH and enabled you to do something of a kind calc 5 + 28.3*sqrt(12) and it spit out the result. Anyone know of any such these days? Doesn't need to do anything fancy ... maybe it would just be nice if it had support for exponentials, but that's it. Anyone? p.s. Not interested in full blown solutions like Python or MATLAB.

• USB Keyboard works occasionally

  - by palimmo

  A few days ago I bought a SL640 Hama USB keyboard to use on my laptop with Ubuntu 12.04. But I'm having problems, as it works one time out of 10! While on my girlfriend's laptop, with Win Vista, always works. And on my laptop I have Win7 in dual boot. And I have to say that it always works on it. Here are some infos: ~$ lsusb Bus 006 Device 003: ID 04d9:1503 Holtek Semiconductor, Inc. Shortboard Lefty As you can see, the OS recognized it but the keyboard doesn't react ... even the Caps Lock and Num Lock keys don't blink. Regarding the legacy support (useful for GRUB), I have found no entry in the BIOS. But I'm not interested in it. I just want to use it in Ubuntu. However, in GRUB it works sometimes. Surprisingly, now I have booted my laptop: the usb keyboard hasn't worked in GRUB but it has worked since the ubuntu login! And now I'm typing with it. Well.. it means that Ubuntu has the right drivers and they work. But how to "load" them always correctly? thanks in advance!

• Web Content Filtering for Windows Clients

  - by djoyce

  I'm working with a small business to solve a bunch of problems. One is their Windows 7 POS registers need to have web access restricted to only three remote support sites, but the back office machine needs an unfiltered connection. I'd like something I can install and configure on the few registers to block all but those few sites. In a perfect world this would restrict the normal register user, but the admin user would not be filtered. Free is best, if it works, but a small fee would be alright too. Microsoft's Family Safety filter is close, but requires a Windows Live account, which isn't ideal, but may be alright. Anyone use this in a small business environment? I'd prefer something easily managed at the local machines. K9 Web Protection is interesting and I'm going to look into it more. Are there other options? Seems like someone would have made something simple like this as an open source project, but maybe not.

• Import EML emails into Outlook 2010 64-bit

  - by nness

  Evening everyone. I'm helping setup a small office network, where a number of old PC's are being replaced with new ones with a 64-bit copy of Outlook 2010. The old emails were stored in Windows Live Email, and were exported as .eml files (since we were replacing the machines). All the support I can find indicates that .eml files could simply be dragged-and-dropped into a folder in Outlook 2010, and it will import them correctly. However, it seems this is not the case in the 64-bit versioin, where dropping in .eml files results in a new message being created with these files as attachments. We can re-download the most of the emails off the server if need be, but there were user folders which were not on the server which we were hoping to import. Any advice would be fantastic at this point!

• Installing ubuntu server as linux distro on dell server - what drivers will be missed

  - by Cookie

  Dell (via USC) unpacks specific drivers for both RedHat and Suse to use after installation on its servers. As Ubuntu server isn't officially supported, this clearly isn't happening for Ubuntu. Is Ubuntu server then running with native drivers? In that case, which drivers are native with Ubuntu, and aren't (e.g. are Dell replaced) with RedHat/Suse? Are dell optimized drivers available for Ubuntu somewhere? Can the ones for RedHat or Suse be used with Ubuntu? Are there disadvantages of this lack of fine-tuned drivers, and if yes, what are they? Would they make the switch (and extra costs, as both RedHat and Suse Enterprise aren't cheap) away from the free Ubuntu server worthwhile? Dell recommends Canonical's commercial support for Ubuntu server on its machines, is this recommendable? Do they offer fine-tuned Dell drivers to replace native drivers?

• True column-mode (block-selection and editing) text editor solution?

  - by tamale

  In windows, I used to use a text editor called crimson editor which featured the best column-mode editing support I have yet to use. When enabled via a simple Alt-C shortcut, selections could be made with the mouse or cursor keys and they would be visual blocks rather than wrapped-lines. These selections could be deleted, moved, copied, pasted, and all of the operations just made sense. You could also just start typing, and you'd get a column of the characters as you're typing. There are multiple ways of getting parts of the these features working separately discussed on this forum thread, but no one has yet to provide a solution that provides this all-encompassing and easy-to-use method. If someone could point me to a gedit plugin where this work is actively being pursued, perhaps I could help with the coding myself. If someone is aware of a text editor that already provides this full functionality, I'd appreciate the info. Running crimson editor through wine and the close-but-not-quite multi-edit plugin for gedit are the temporary solutions I'm 'getting by with' for the time being.

• Change Scan-to-PC list names on Brother MFC-8890DW Printer

  - by dralezero

  I have two Brother MFC-8890DW. When scanning over the network, it shows a list of PCs (on the scanner display) to save to that have the software/drivers installed. Each PC is listed as the name of the employee for that computer. I have setup a third MFC-8890DW and installed on these computers. The list, however, is the computer name. Somehow it is possible to customize the name. Brother support did not know. I couldn't find anything in manuals. I thought I remember setting up those names before.

• Ubuntu 12.04 startup is slow and dmesg output seems to lose several seconds

  I use ubuntu on Dell Inspiron n4050.I have upgraded to ubuntu 12.04 from 10.04. But now I find the system startup is a little slow and plymouth only show purple screen without logo during startup. When I use dmesg, it shows such messages: [ 2.497750] EXT4-fs (sda1): mounted filesystem with ordered data mode.

Is this the reason dmesg lost output?

• Update 3 for "NetBeans Platform for Beginners"

  - by Geertjan

  The latest monthly update of NetBeans Platform for Beginners was released during the last few days. Without any question at all, this book is awesome. I love how it is a 'living book' and that on a monthly basis new updates are made available. In this particular update, as before, reader comments and questions have led to changes and enhancements in the book. In addition, there's now a tighter integration between the long list of samples on GitHub and the book, since wherever a sample relates to a text in the book, the book has a handy icon, so that you know when to hop over to GitHub to get a related sample. Do you have comments or questions about the book? That's what the feedback link is for: https://leanpub.com/nbp4beginners/feedback And there's also a free sample, just in case you'd like to get a feel for the book prior to buying it: http://samples.leanpub.com/nbp4beginners-sample.pdf If you're from a company where you're all sharing a single copy of the book, it would be great if you'd go back and support this great project (and hopefully encourage future books being written) by buying additional copies, ideally one for each developer. Let's show the authors that writing books on the NetBeans Platform is a really profitable thing to do (and I'm hoping they'll write one on Maven and the NetBeans Platform, as well)!

• Why are Win7 IE browers running in IE7 mode?

  - by Skurpi

  On our site we currently have approx. 50% of our IE7 users running Windows 7. However, Win7 was released with IE8 meaning that something is not right. Based on this, we made the assumption that the modern IE browsers enter IE7 compatibility mode on our site. So we placed the "X-UA-Compatible=edge" meta tag on our site in hope to kill off IE7 support. However, after a week, the percentage of IE7 (and IE8) users have gone up for the first time since the start of this year. When looking at the X-UA-Compatible documentation, it is meant to be used for putting your site into an older mode. Is there any other way to make sure that IE doesn't enter compatibility mode? Is there something else we need to look for? And yes, we have so many users on our site that we can't kill off IE7 until it goes down under 2% of unique visitors. EDIT: We use <!doctype html> EDIT2: We haven't been able to reproduce the compatibility mode in our environments either

• Suggestions for hosted file sharing services

  - by Jon

  Before I pose my question, I will give some insight as per my scenario: I work for a small business (cost is an important factor) Our bandwidth is limited and would not support an in-house FTP server We need to share files (mostly pdf, inDesign, Illustrator documents) to our clients, and as we expand, we are finding that our current locally-hosted FTP solution is too slow and is becoming a detriment to our sales team. What we need is a remotely hosted solution to share files with our clients, specifically with the following features: Greater than 100gb of secure storage The Ability to distribute unique log in credentials to clients, granting access to a personalized directory or folder, while limiting access to other files on the server. A relatively simple web-based UI for clients with limited computer knowledge We have considered a dedicated remote server, and web-based services (box.net, yousendit.com, onehub.com, filesanywhere.com) but I am unsure as per the direction we should be taking - have I left another solution out? What would you suggest? Thanks in advance.

• ADSL improvement in recent years

  - by cleong

  Currently I have a 2mb/s ADSL connection. I signed up for the service more than five years ago. Has technology improved much during that time to allow for greater speed using the same wires? The building I live in is quite old and the lines aren't very good. They weren't able to support 6mb/s service back then. Now I notice that the lowest speed offered by my telco is 10mb/s. Even that would be a serious improvement over what I have now. Here are the stats from the modem: Line Attenuation (Up/Down) [dB]: 10,5 / 15,5 SN Margin (Up/Down) [dB]: 31,5 / 29,0

• Scroll bar for vim(curses-based one, not gvim)?

  - by xiaq

  As a Linux user, I have been quite comfortable with CLI and TUI tools, but I miss the little scrollbar present in almost every GUI program. It has always been easier for me to know how long the file is and where I am from the scrollbar instead of "9752 lines, 24%". What I expect is a ASCII scrollbar that looks like | | | | # # # | | | and I can configure to appear on the left or right (and if on the left, the relative position to line numbers and fold marks). Is there already a Vim plugin to do this, or how can I write my own one? Vim's plugin framework doesn't seem to support such UI modifications directly.

• How does Windows 7 determine that a system was not shut doen correctly (Kernel-Pwer Event ID 41)

  - by Erik

  I have a strange situation that Windows 7 thinks it was not shut down correctly, and gives me a warning in the system event log like this: http://support.microsoft.com/kb/2028504/de What the KB-article does not tell is how Windows actually determines that situation. Does it parse its own system event log after reboot? Or where does it get that information from? I am currently investigating an issue where I believe the system fails to write the system event log correctly (it stops having entries, although other logs like the application event log still have entries), and after a reboot, Windows thinks it has not been shut doen correctly. Does anybody have any experience with this? ANd can you confrim that Windows determines the previous correct system shutdown by parsing its own system event log on startup?

• Dell Vostro 3500 battery life remaining missing from Windows 8?

  - by Misha

  On Windows 7 a Vostro 3500 laptop shows the battery life remaining, while on Windows 8 this information appears to be missing. The percentage is still available, but the life remaining is missing. How is battery life remaining calculated and does this require some level of driver support? Is it a standardized interface? Does anybody know which driver is responsible for handling this feature? I want to force the old Windows 7 driver, but I don't know which driver does battery remaining.

• Excel Countif external date

  - by Duall

  I am making an Excel 2010 spreadsheet to log support calls, services, and installations that each member would fill out. Due to being paid by job rather than by hour, there is a need for it to count each of these ("Call", "Service", "Install") there is in any given time span. The entry of the data itself would be in Sheet 1, and then a 'splash screen' of sorts would be in Sheet 2. Here I would like to be able to put a date range and it would display how many of each there is. I already can do the COUNTIF statement, =COUNTIF(Activity!$B:$B,"Call") but I don't know how to: a) Add in the prerequisite for a date so it only gets "Calls" within a certain time frame. b) Take the date it looks for from a cell on the splash screen.

• Can't access computer

  - by Pudica

  I'm running Ubuntu 14.04 on an Intel NUC and it won't boot! The last successful boot was earlier today but now each time I try it gets stuck on the Grub menu where it prompts for memory check etc. This is not a dual boot system, so this screen shouldn't ever appear, and it never has before. It's GRUB version 2.02~beta2-9, which is a little disconcerting, as I'm on the stable sources. Unfortunately the keyboard (I've tried 2 keyboards just in case) is not responding at this point in the boot process, so I can't select the "Ubuntu" menu option in Grub. The keyboard works during the bios stage, so I can configure it to boot from USB, and I tried a flash drive with 14.04 on it. The flash drive works in my laptop but is completely ignored by the NUC (I tried all 3 USB ports!). It seems that I have no way of getting into the machine at all! The Intel support site was my first option, but the site is down. I expect it's a long shot, but if anyone has any ideas I'd be very grateful.

• Route a specific user's traffic via VPN but still allow local networking

  - by wbg

  So, I want to route certain traffic via a VPN connection and the rest via my normal Internet connection. I want to run several different programs and most of them don't support binding to a specific network interface (tun0 in my case). I've managed to send a specific user's traffic via the VPN following the answers given here: iptables - Target to route packet to specific interface? But unfortunately, when I run a server that connects to the Internet and has a web interface running on a local IP (127.0.0.1/192.168.0.*), all the Internet traffic correctly goes via tun0, but I'm unable to connect to the web interface from a local IP as a different user. When I log in as the VPN-ified user, I can access services running on local IPs, but other users/machines can't access any servers I start. Can anyone point me in the right direction?

• Is it possible to boot from internet?

  - by Calmarius

  Let's assume the following situation: you have a computer with empty hard disk, and you don't have a CD, floppy, pen drive nearby to boot the computer from. But you have connection to the Internet. Modern computers support network booting using PXE, but I haven't found anything regarding booting via the internet. So, is it possible to use PXE to load an image from the internet and boot it? By having a running system (even a minimal Linux) in RAM, it should be possible to install it on the hard disk, and build up a working system from here.

• Lubuntu fails plug and play such as scanners; default file location on Gnumeric

  - by Arkay

  I am new to Lubuntu and I have been giving it a good try but confess I am now tempted to go back to Windows. However, I am open to persuasion if I can get a simple answer to two questions. The first is a hardware question issue. It seems from the forum that many users like me cannot use plug and play hardware such as scanners. Are we doing anything wrong or does Lubuntu (mine is 13.04) not support plug and play or scanners? I have read lots of previous answers about scanners but they all seem to involve re-writing lines of instructions to various areas of the system - not something an amateur like me can do with ease. Mine is a Packard Belle Diamond 1200 plus and apparently it should work fine on Lubuntu - but can I even get it recognised, let alone working - No? Secondly is there an easy way in Gnumeric to set the default file location so that I don't have to trawl through my whole tree to locate a file I want to open? Thanks to anybody who can get me stay with Lubuntu with their wisdom.

• What version of Windows server is needed for RemoteApp functionality?

  - by consolibyte

  We have a Windows desktop app that we want to make available over the Internet to a few users. What version of Windows Server do I need for that RemoteApp functionality? I tried to figure this out via Microsoft's website, but I couldn't get a clear bead on how exactly what YEARS (2008, 2012, etc.) and/or what EDITIONS (Data Center vs. Standard vs. Foundation vs. Essentials) of Windows Server support RemoteApp stuff.
