  • Beginner Geek: How to Use Multiple Monitors to Be More Productive

    - by Chris Hoffman
    Many people swear by multiple monitors, whether they’re geeks or just people who need to be productive. Why use just one monitor when you can use two or more and see more at once? Additional monitors allow you to expand your desktop, getting more screen real estate for your open programs. Windows makes it very easy to set up additional monitors, and your computer probably has the necessary ports. Why Use Multiple Monitors? Multiple monitors give you more screen real estate. Hook up multiple monitors to a computer and you can move your mouse back and forth between them, dragging programs between monitors as if you had an extra-large desktop. People who swear by multiple monitors use them to display multiple things on-screen at a time. Rather than Alt+Tabbing and task switching to glance at another window, you can just look over with your eyes and then look back to the program you’re using. Some examples of use cases for multiple monitors include: Coders who want to view their code on one display with the other display reserved for documentation. They can just glance over at the documentation and look back at their primary workspace. Anyone who needs to view something while working. Viewing a web page while writing an email, viewing another document while writing an something, or working with two large spreadsheets and having both visible at once. People who need to keep an eye on information, whether it’s email or up-to-date statistics, while working. Gamers who want to see more of the game world, extending the game across multiple displays. Geeks who just want to watch a video on one screen while doing something else on the other screen. Hooking Up Multiple Monitors Hooking up an additional monitor to your computer should be very simple. Most new computers come with more than one port for a monitor — whether DVI, HDMI, the older VGA port, or a mix. Some computers may include splitter cables that allow you to connect multiple monitors to a single port. Most laptops also come with ports that allow you to hook up an external monitor. Plug a monitor into your laptop’s DVI or VGA port and Windows will allow you to use both your laptop’s integrated display and the external monitor at once. This all depends on the ports your computer has and how your monitor connects. If you have an old VGA monitor lying around and you have a modern laptop with only DVI or HDMI connectors, you may need an adapter that allows you to plug your monitor’s VGA cable into the new port. Be sure to take your computer’s ports into account before you get another monitor for it. Managing Multiple Monitors With Windows Windows makes using multiple monitors easy. Just plug the monitor into the appropriate port on your computer and Windows should automatically extend your desktop onto it. You can now just drag and drop windows between monitors. To control how this works, right-click your Windows desktop and select Screen resolution. Choose an option from the Multiple displays box. The Extend option extends your desktop onto an additional monitor, while the other options are mainly useful if you’re using an additional monitor for presentations — for example, you could mirror your laptop’s desktop onto a large monitor or blank your laptop’s screen while it’s connected to a larger display. Be sure to arrange your monitors properly so Windows understands how your monitors are physically positioned. Windows 8 allows you to extend your Windows taskbar across multiple monitors. You’ll find this option in the taskbar’s options window — right-click the taskbar and select Properties. You can also choose where you want Windows to display taskbar buttons for open programs — on any monitor’s taskbar or only on the taskbar on the associated monitor. Windows 7 doesn’t have these convenient features built-in — your second monitor won’t have a taskbar. To extend your taskbar onto an additional monitor, you’ll need a third-party utility like the free and open-source Dual Monitor Taskbar. If you just have a single monitor, you can also use the Aero Snap feature to quickly place multiple Windows applications side by side. On Windows 7 or 8, press Windows Key + Left or Windows Key + Right to make the current window take up the left or right half of your display. You could also drag any window’s title bar to the left or right edges of your screen and release the window. How useful this feature is depends on your monitor’s size and resolution. If you have a large, high-resolution monitor, it will allow you to see a lot. If you have a smaller laptop monitor with the seemingly standard 1366×768 resolution, you won’t be able to see much of each snapped window at once, so snapping windows may not be practical.

  • Building a custom Xsession with VNC access

    - by Disco
    I have a small project where I'll need to build a very minimal X11 environnement for a cyber coffee kind shop. My idea is to have a simple server which will create a dozen of VNC Daemon listening on a different port (each port = one client). The server is working, i can connect using vnc to different port. Now i'm looking for a solution to create a customized desktop for each client; with a bare minimum of apps which i want to be able to add for each user. Like user1 will have app1 and app2, user2 will have app1 only etc. I plan to use openbox as a WM but no clue on 'how' to add custom icons on the desktop of it. Any clue, starting point would be interesting.

  • FTP over ssh hangs on "Connection established: Waiting for Welcome Message"

    - by Siriss
    I have looked far and wide and have not quite found the answer. I am running ubuntu 11.10, openssh, and vsftpd. I am trying to configure my FTP to tunnel over ssh. My ssh connection works just fine and I can create the tunnel to my FTP port. When I go to use Filezilla to connect, it hangs at "Waiting for Welcome Message". I think it is an iptables issue, but I can't seem to figure out what needs to be changed. When I take iptables down, it connects just fine. I don't want to open any more external ports, just my one SSH port, and I can't seem to get it right on the internal port forwarding rule. I always end up opening it to the outside. I would love some help if anyone has any ideas and I hope I have made it clear. Thank you in advance!!

  • using GNU GPL v2 software as pointers to solution to problem

    - by Patrick
    I am coding a PHP serial access class and have been taking pointers from the PHP-serial class on Google Code (here). That class is based on PHP 4 and I'm creating a PHP 5 class that allows more functionality and is specific to some business demands I have. There is no code copied and I have done all the coding. Does the class I'm writing fall under the Google Code's GPL or am I free to select a license that I feel is appropriate? I'm not sure of the standard that applies to licensing when you are only looking to another work for pointers.

  • Windows VirtualBox can't browse network

    - by Don Kirkby
    I'm running Windows XP as a VirtualBox guest OS under Ubuntu 11.10, and I can't browse the Windows network. It seems like I can connect to some specific network shares, maybe only ones that are already mapped to drives. If I disable ufw, it all works fine, and when I enable it again, the network browsing continues to work. I tried looking at /var/log/ufw.log and saw it blocking port 138. When I allowed that port, then I saw it blocking port 137. I found this answer, and it led me to bug 360975. The bug originally asked for both nf_conntrack_pptp and nf_conntrack_netbios_ns to be added to the defaults, but in comment 11, Jamie decided not to include nf_conntrack_pptp in the fix. I tried adding it in, and it seemed to solve my problem, but then the problem came back. How can I let the Windows guest OS browse the local network?

  • Is there a difference between multi-tasking and time-sharing?

    - by Dummy Derp
    Just going over my school notes, my teacher identifies multi-tasking OS, and time-sharing OS as two different things. I really don't see a difference between the two. MULTI-TASKING: You load a number of programs in the memory and execute them. You execute another program if the time quantum allocated to the current program expires OR if it goes on to do I/O and leaves the CPU OR if it finishes execution. TIME-SHARING: the same,again. The same applies in case of serial processing and batch processing. Although they are the same, I guess the only difference would be the way in which control information is passed to the CPU. Maybe, and again MAYBE, in serial processing you need to provide the punch cards with all the processes while in batch, the entire batch uses the same set of control information. Like all the print jobs would have the same control information.

  • Unable to connect with IIS7 Manager to remote site

    - by saifkhan
    I was unable to connect with IIS7 manager to a remote site. I got on the phone with the hosting provider and they started troubleshooting. After a few minutes they went over all my settings, username, password...the whole shebang and I still couldn't. I then asked the support tech if any ports needed to be opened on my side and she said "ONLY PORT 80 NEEDS TO BE OPENED"... after a few more mins I decided to hop over to the IIS7 website but still couldn't find anything incicating specific ports, but I did came across a doc mentioning 8172 as a port IIS7 uses so I went to my firewall did the following OPEN PORT 8172 OUTBOUND That did the trick!...and the support tech updated her document accordingly.

  • Illuminated USB keyboard flickers

    Does anyone know where I can download a driver for the VAKOSS TK-487-UK illuminated keyboard to run on Ubuntu? Or at least how to control the USB port so that it stops flickering on and off. The USB port works fine but the Keyboard is not recognized by Ubuntu...

'~$ nc -z -v T43 1-1024' prints 'Connection to T43 22 port [tcp/ssh] succeeded!' and 'nc: connect to T43 port 1000 (tcp) failed: Connection refused.' 'man nc': "PORT SCANNING: It may be useful to know which ports are open and running services on a target machine. The -z flag can be used to tell nc to report open ports, rather than initiate a connection. For example: '$ nc -z host.example.com 20-30'.

  • Problem serialising TextBuffer

    - by njallam
    The following is supposed to serialise a TextArea's content to a string. The first two line complete fine, however I have problems from then onwards. page_content = subject_content.get_nth_page(pn) page_name = subject_content.get_tab_label(page_content).get_text() c_buffer = page_content.get_buffer() c_format = c_buffer.register_serialize_tagset() serial = c_buffer.serialize(c_format, c_buffer.get_start_iter(), c_buffer.get_end_iter()) The first error I get is: Traceback (most recent call last): File "/home/nja/notetaker/notetaker/NotetakerWindow.py", line 251, in on_btn_save_clicked self.save() File "/home/nja/notetaker/notetaker/NotetakerWindow.py", line 160, in save c_format = c_buffer.register_serialize_tagset() File "/usr/lib/python2.7/dist-packages/gi/types.py", line 43, in function return info.invoke(*args, **kwargs) TypeError: register_serialize_tagset() takes exactly 2 arguments (1 given) When inserting None as a parameter to c_format = c_buffer.register_serialize_tagset() I get the following as well: Traceback (most recent call last): File "/home/nja/notetaker/notetaker/NotetakerWindow.py", line 251, in on_btn_save_clicked self.save() File "/home/nja/notetaker/notetaker/NotetakerWindow.py", line 161, in save serial = c_buffer.serialize(c_format, c_buffer.get_start_iter(), c_buffer.get_end_iter()) File "/usr/lib/python2.7/dist-packages/gi/types.py", line 43, in function return info.invoke(*args, **kwargs) TypeError: serialize() takes exactly 5 arguments (4 given) I have no idea of a workaround for that, however I shouldn't have to fill None in that other function in the first place. What is happening here?

    I have created a bootable USB drive using SYSLINUX I am booting my x86 system correctly. Once system boots I want to stop at console (command prompt) where I can type linux commands (cd etc) and run my executable file manually.

  • jQuery / jqGrids / Submitting form data troubles...

    - by Kelso
    Ive been messing with jqgrids alot of the last couple days, and I have nearly everything the way I want it from the display, tabs with different grids, etc. Im wanting to make use of Modal for adding and editing elements on my grid. My problem that Im running into is this. I have my editurl:"editsu.php" set, if that file is renamed, on edit, i get a 404 in the modal.. great! However, with that file in place, nothing at all seems to happen. I even put a die("testing"); line at the top, so it sees the file, it just doesnt do anything with it. Below is the content. ........ the index page jQuery("#landings").jqGrid({ url:'server.php?tid=1', datatype: "json", colNames:['ID','Tower','Sector', 'Client', 'VLAN','IP','DLink','ULink','Service','Lines','Freq','Radio','Serial','Mac'], colModel:[ {name:'id', index:'id', width : 50, align: 'center', sortable:true,editable:true,editoptions:{size:10}}, {name:'tower', index:'tower', width : 85, align: 'center', sortable:true,editable:false,editoptions:{readonly:true,size:30}}, {name:'sector', index:'sector', width : 50, align: 'center',sortable:true,editable:true,editoptions:{readonly:true,size:20}}, {name:'customer',index:'customer', width : 175, align: 'left', editable:true,editoptions:{readonly:true,size:35}}, {name:'vlan', index:'vlan', width : 35, align: 'left',editable:true,editoptions:{size:10}}, {name:'suip', index:'suip', width : 65, align: 'left',editable:true,editoptions:{size:20}}, {name:'datadl',index:'datadl', width:55, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from datatypes"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'dataul', index:'dataul', width : 55, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from datatypes"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'servicetype', index:'servicetype', width : 85, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from servicetype"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'voicelines', index:'voicelines', width : 35, align: 'center',editable:true,editoptions:{size:30}}, {name:'freqname', index:'freqname', width : 35, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from freqband"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'radioname', index:'radioname', width : 120, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from radiotype"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'serial', index:'serial', width : 100, align: 'right',editable:true,editoptions:{size:20}}, {name:'mac', index:'mac', width : 120, align: 'right',editable:true,editoptions:{size:20}} ], rowNum:20, rowList:[30,50,70], pager: '#pagerl', sortname: 'sid', mtype: "GET", viewrecords: true, sortorder: "asc", altRows: true, caption:"Landings", editurl:"editsu.php", height:420 }); jQuery("#landings").jqGrid('navGrid','#pagerl',{edit:true,add:true,del:false,search:false},{height:400,reloadAfterSubmit:false},{height:400,reloadAfterSubmit:false},{reloadAfterSubmit:false},{}); now for the editsu.php file.. $operation = $_REQUEST['oper']; if ($operation == "edit") { qquery("UPDATE customers SET vlan = '".$_POST['vlan']."', datadl = '".$_POST['datadl']."', dataul = '".$_POST['dataul']."', servicetype = '".$_POST['servicetype']."', voicelines = '".$_POST['voicelines']."', freqname = '".$_POST['freqname']."', radioname = '".$_POST['radioname']."', serial = '".$_POST['serial']."', mac = '".$_POST['mac']."' WHERE id = '".$_POST['id']."'") or die(mysql_error()); } Im just having a hard time troubleshooting this to figure out where its getting hung up at. My next question after this would be to see if its possible to make it so when you click "add", that it auto inserts a row into the db with a couple variable predtermined and then bring up the modal window, but ill work on the first problem first. thanks!

  • getting a pyserial not loaded error

    - by skinnyTOD
    I'm getting a "pyserial not loaded" error with the python script fragment below (running OSX 10.7.4). I'm trying to run a python app called Myro for controlling the Parallax Scribbler2 robot - figured it would be a fun way to learn a bit of Python - but I'm not getting out of the gate here. I've searched out all the Myro help docs but like a lot in-progress open source programs, they are a moving target and conflicting, out of date, or not very specific about OSX. I have MacPorts installed and installed py27-serial without error. MacPorts lists the python versions I have installed, along with the active version: Available versions for python: none python24 python25 python25-apple python26 python26-apple python27 python27-apple (active) python32 Perhaps stuff is getting installed in the wrong places or my PATH is wrong (I don't much know what I am doing in Terminal and have probably screwed something up). Trying to find out about my sys.path - here's what I get: import sys sys.path ['', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC', '/Library/Python/2.7/site-packages'] Is that a mess? Can I fix it? Anyway, thanks for reading this far. Here's the python bit that is throwing the error. The error occurs on 'try import serial'. # Global variable robot, to set SerialPort() robot = None pythonVer = "?" rbString = None ptString = None statusText = None # Now, let's import things import urllib import tempfile import os, sys, time try: import serial except: print("WARNING: pyserial not loaded: can't upgrade!") sys.exit() try: input = raw_input # Python 2.x except: pass # Python 3 and better, input is defined try: from tkinter import * pythonver = "3" except: try: from Tkinter import * pythonver = "2" except: pythonver = "?"

  • Cisco router not receiving OSPF updates

    - by WebDevHobo
    Or at least, that's what I think is happening. There doesn't appear to be a debug command for this, or to see if something is in the routing table. I'm testing out this setup in Packet Tracer. I have 3 routers and a webserver From left to right, you have: Webserver - Router1 - Router2 - Router3 Router1 and Router2 can succesfully ping WebServer. Router3 cannot. Router2 has a default gateway set, to send all not-recognized data through its serial interface to Router1. Like this: ip route 0.0.0.0 0.0.0.0 Serial 0/0/1 Serial 0/0/1 being the connection to Router1 Router2 and Router3 have OSPF configured. From their "show run": Router2: router ospf 1 log-adjacency-changes passive-interface Serial0/0/1 network 10.1.1.0 0.0.0.3 area 0 default-information originate ! Router3: router ospf 1 log-adjacency-changes network 10.1.1.0 0.0.0.3 area 0 passive-interface FastEthernet0/0 ! I was under the assumption that setting default-information originate on Router2 would give Router3 the needed information. What's going wrong here? The interfaces are up. Ip addresses are with mask-range, clock rate is set at correct end. I don't know what else to check.
