  • How do I get a different type of scrollbars in 12.04? [closed]

    - by Joseph Garvin
    Possible Duplicate: How do I disable overlay scrollbars? By default 12.04 uses overlay scroll bars that do not suit my taste, and every method I've found so far of disabling them makes them broken in a different way. When I was using 11.10 this wasn't a problem because I could still change the GTK theme. In 12.04, the Appearance settings only contain a few stock themes, and other than the special purpose contrast ones they all have the overlay scroll bars. If I aptitude search gtk3 | grep theme I get no results so there appears to be no packaged alternative either. Most suggestions I've seen for disabling the overlay scroll bars involve uninstalling packages or editing files as root. I want to disable them just for the current user, not for everyone on the whole box; as should be the case for any theme/display setting. There is a gsettings command that temporarily disables the overlay scrollbars just for the current user, but this has two problems of its own: The setting doesn't stick after log off. Because who would want to save settings? The scroll bars put in place have no contrast. They have a black scroller on a black background and are completely unusable. In short what I'd like to know is how to disable overlay scroll bars such that: My preference is user specific. My preference is actually saved. The scroller can actually be seen against the background without having to use a special high contrast theme that makes my whole desktop look like a negative photo from Tron.

  • How can I make refactoring a priority for my team?

    - by Joseph Garland
    The codebase I work with daily has no automated tests, inconsistent naming and tons of comments like "Why is this here?", "Not sure if this is needed" or "This method isn't named right" and the code is littered with "Changelogs" despite the fact we use source control. Suffice it to say, our codebase could use refactoring. We always have tasks to fix bugs or add new features, so no time is put aside to refactor code to be better and more modular, and it doesn't seem to be a high priority. How can I demonstrate the value of refactoring such that it gets added to our task lists? Is it worth it to just refactor as I go, asking for forgiveness rather than permission?

  • Ubuntu 12.10 dual boot windows 7 not working

    - by Joseph
    When i install ubuntu, and the computer restarts it doesn't show the boot managaer so it always boots in windows 7. I tried to change the default os, and ubuntu wasn't even listed in it. Then I read a how to on it, it showed how to size the partions and make them correctly, but it still didn't work. I tried easyBCD and still no success. I've tried installing it about 4-5 times and i still can't get it. What can i do to fix it?

  • Going from a math career to a cs career: how to do it?

    - by Joseph
    Hey, I'm looking for some advice on how to successfully make the transition from mathematics to CS. My academic background is in mathematics (BS and MSc), and I've taken loads of math courses as well. You name it, and I took it: Measure Theory, Algebra, PDES, Manifolds, Complex Analysis, etc. I progressed quite far along this track, and at one point, I thought I would be a professional mathematician...But around the time I was finishing my MSc, I really got sick of it. Studying very abstract mathematics was fun, but it really lost it's appeal to me. Outside of a couple hundred people, I'm not sure if anybody would understand my research. I did not want to be 60 years old and say that my only contribution to the world consisted of published papers. Anyways, I've been an off and on hobbyist programmer since 2002. I've programmed in C and Java (just small projects), and I really started to be drawn to the area as time passed. There's a real appeal to CS work because, well, it actually means something to other people out there! I enjoy all parts of it: designing webpages (a real artistic appeal). On the other end, I do enjoy toying with compilers and more nitty-gritty stuff as well. Suffice to say, I have broad interests out there. Anyways, I know it's a bit late, but I was wondering if there were other folks out there who made the change, and if so, how I could do so. I know I have some fairly big gaps to fill in terms of data structures, lack of internship experience, etc. But I really would like to make this work. So my question is simply: How can I make the switch from math to CS? To pay the bills, I'll be doing financial analysis for a company, but I'd like to eventually transition into a developer type position. I've been reading "Algorithm Design" by Tardos and doing all the problems. It's not hard to make progress since the problems are far more concrete than the stuff I've been doing the past six years. I feel I can make fairly rapid progress in picking up all the materials from data structures, etc. but none of it can substitute the past several years I've lost. Anyways, I'm eager to learn but would love some advice/concrete direction. Thanks, Joseph

  • What's the best way to create a Windows Mobile application with multiple screens in C#

    - by Joseph Earl
    I am creating a Windows Mobile Application in C# and Visual Studio 2008. The application will have 5-6 main 'screens'. There will also be bar (/area) with information (e.g. a title, whether the app is busy, etc) above the screens, and a toolbar (or similar control) below the screens with 5-6 buttons (with images) to change the active screen (i.e. the screens will share the top bar and toolbar) What is the best way to implement this? Use multiple forms, and just include the toolbar and top-bar in each Use a single form and something like the Tab control (but customised) to contain the screens Something else? Keeping in mind a) memory usage and b) time to switch screens. Thanks in advance. Any links, pointers etc are much appreciated.

  • Replacing text in NSTextFieldCell inside NSTableView

    - by earl.ct
    Whenever a user would type a number, my app would automatically prepend a currency sign before that number. For example, when the user types "1" in a text field, the text inside it becomes "$1.00". All is good when I use an NSNumberFormatter, an NSTextField, and its delegate method control:didFailToFormatString:errorDescription:. - (BOOL)control:(NSControl *)control didFailToFormatString:(NSString *)string errorDescription:(NSString *)error { if ([[control formatter] isKindOfClass:[NSNumberFormatter class]]) { NSNumberFormatter *formatter = [control formatter]; if ([formatter numberStyle] == NSNumberFormatterCurrencyStyle && ! [string hasPrefix:[formatter currencySymbol]]) { NSDecimalNumber *new = [NSDecimalNumber decimalNumberWithString:string]; if (new == [NSDecimalNumber notANumber]) { new = [NSDecimalNumber zero]; } [control setObjectValue:new]; } } return YES;} Now I would like to have this functionality when a user types a number in a cell inside an NSTableView. I tried using control:didFailToFormatString:errorDescription: but the cell would erase the text instead.

  • How to place an element at the bottom of a page, without declaring a position?

    - by Earl Larson
    I have a row of icons that need to be at the bottom of the page, they also need to be fixed. Simple, right? Not. When you position them fixed, the icons fall into one another so only one icon shows. Well there goes that, but there also goes the chance of placing them at the bottom of the page since I need #icons { position:fixed; bottom:0; } I could always manually place them, but this means they cant be fixed like I need them too, and I would have to declare it for different browsers. Help? Link to website: Roseannebarr.tumblr.com Here is an example of my HTML <div id="outer"> {block:Photo} <img id="block" src="http://static.tumblr.com/ux4v5bf/vYSlebvt2/photo.png"> <div id="tooltip"> {LinkOpenTag}<img id="photo" src="{PhotoURL-500}" alt="{PhotoAlt}" />{LinkCloseTag} {block:Caption}<div class="caption">{Caption}</div>{/block:Caption} </div> {/block:Photo} </div>

  • Make a view to be the primary one in navigation controller?

    - by Earl Grey
    I am using a tabbar, each tab having a navigation controller, and this in turn having a stack of views. Each view is having its own view controller but this is not important now. Lets have a tab 1 with a navigation controller 1 with views A, B, C. The nature of the application dictates however that the view B is the primary one. So what I want is that by default (after first or after relaunch of the app), when I tap the tab 1, I will see the B view together with the back button to A view. How can I achieve this?

  • How to achieve vertical div alignment in unique situation?

    - by Earl Larson
    Go to my blog and please tell me how to achieve vertical alignment :( My situation truly is different and I need help :) The reason this is so difficult is because holder is the div that contains everything, outer are the icons at the bottom, and tooltip are the divs that pop up. I need tooltip to be vertically aligned but they are actually below outer. Each icon is connected to their post so you can't keep them all in one div.

  • Replace Components.classesByID with document.implementation.createDocument

    - by Earl Smith
    I am not the author of this code, but it is no longer maintained. So I am trying to fix it, but I have very little experience in javascript. Since Firefox 9, Components.classesByID["{3a9cd622-264d-11d4-ba06-0060b0fc76dd}"]. has been obsolete. Instead, it is suggested that document.implementation.createDocument be used. Can someone here show me how to implement these changes? I seem to be, just banging my head with everything I have tried. The example given at Mozilla developer network is: var doc = document.implementation.createDocument ("http://www.w3.org/1999/xhtml", "html", null); var body = document.createElementNS("http://www.w3.org/1999/xhtml", "body"); body.setAttribute("id", "abc"); doc.documentElement.appendChild(body); alert(doc.getElementById("abc")); // [object HTMLBodyElement] and the code in the .jsm I am trying to fix is: this.fgImageData = {}; this.fgImageData["check"] = [ " *", " **", "* ***", "** *** ", "***** ", " *** ", " * "]; this.fgImageData["radio"] = [ " **** ", "******", "******", "******", "******", " **** "]; this.fgImageData["menu-ltr"] = [ "* ", "** ", "*** ", "****", "*** ", "** ", "* "]; this.fgImageData["menu-rtl"] = [ " *", " **", " ***", "****", " ***", " **", " *"]; // I think I'm doing something slightly wrong when creating the document // but I'm not sure. It works though. *FIX* var domi = Components.classesByID["{3a9cd622-264d-11d4-ba06-0060b0fc76dd}"]. createInstance(Components.interfaces.nsIDOMDOMImplementation); this.document = domi.createDocument("http://www.w3.org/1999/xhtml", "html", null); this.canvas = this.document.createElementNS("http://www.w3.org/1999/xhtml", "html:canvas"); for(var name in this.fgImageData) { if (this.fgImageData.hasOwnProperty(name)) { var data = this.fgImageData[name]; var width = data[0].length; var height = data.length; this.canvas.width = width; this.canvas.height = height; var g = this.canvas.getContext("2d"); g.clearRect(0, 0, width, height); var idata = g.getImageData(0, 0, width, height); for(var y=0, oy=0; y<height; y++, oy+=idata.width*4) for(var x=0, ox=oy; x<width; x++, ox+=4) idata.data[ox+3] = data[y][x] == " " ? 0 : 255; this.fgImageData[name] = idata; } } },

  • Cisco ASA Hairpinning with Dynamic IP

    - by Joseph Sturtevant
    I currently have my Cisco ASA 5505 firewall configured to forward port 80 from the outside interface to a host on my dmz interface. I also need to allow clients on my inside interface to access the host in the dmz by entering the public ip / dns record in their browsers. I was able to do that by following the instructions here, resulting in the following configuration: static (dmz,outside) tcp interface www 192.168.1.5 www netmask 255.255.255.255 static (dmz,inside) tcp 74.125.45.100 www 192.168.1.5 www netmask 255.255.255.255 (Where 74.125.45.100 is my public IP and 192.168.1.5 is the IP of the dmz host) This works great except for the fact that my network has a dynamic public IP and this configuration will therefore break as soon as my public IP changes. Is there a way to do what I want with a dynamic ip? Note: Adding an internal DNS record won't solve my problem since I have multiple dmz hosts mapped to different ports on the public IP.

  • how to fix "BusyBox v1.17.1 (Ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash) Enter 'help' for a list of built-in commands?"

    - by Joseph
    So I was using Ubuntu when suddenly the whole thing froze up and I had to reboot. And from that moment on, the system when it is starting up, prompts this little selection menu: GNU GRUB version 1.99~rc1-13ubuntu3 Ubuntu, with Linux 2.6.38-10-generic ubuntu, with Linux 2.6.38-10-generic (recovery mode) Previous Linux versions Memory test (memtest86+) Memory test (memtest86+, serial console 115200) I have chosen all of the available choices but all I get is another command line system that reads: BusyBox v1.17.1 (Ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs): And honestly I can't do anything with it. Does anyone have any idea of what is going on and how I can get Ubuntu to work again?

  • Setting up Github post-receive webhook with private Jenkins and private repo

    - by Joseph S.
    I'm trying to set up a private GitHub project to send a post-receive request to a private Jenkins instance to trigger a project build on branch push. Using latest Jenkins with the GitHub plugin. I believe I set up everything correctly on the Jenkins side because when sending a request from a public server with curl like this: curl http://username:password@ipaddress:port/github-webhook/ results in: Stacktrace: net.sf.json.JSONException: null object which is fine because the JSON payload is missing. Sending the wrong username and password in the URI results in: Exception: Failed to login as username I interpret this as a correct Jenkins configuration. Both of these requests also result in entries in the Jenkins log. However, when pasting the exact same URI from above into the Github repository Post-Receive URLs Service Hook and clicking on Test Hook, absolutely nothing seems to happen on my server. Nothing in the Jenkins log and the GitHub Hook Log in the Jenkins project says Polling has not run yet. I have run out of ideas and don't know how to proceed further.

  • Ubuntu/Nvidia lists DVI dual cable as single

    - by Joseph Mastey
    I have an NVidia Quadro FX 880M graphics card, from which I am trying to drive 2 monitors: my internal laptop montior (15.6", 1920x1080, Nvidia driver says it's running via DisplayPort) and an external 27" monitor (Dell U2711, 2560x1440 native resolution, via DVI). I've hooked the dual DVI cable to the dual DVI port on my dock (Dell PR03X) and installed the proprietary NVidia driver, but I cannot seem to get the full 2560x1440 out of the larger 27" external monitor. Looking at the NVidia driver settings, the monitor's connection is reported as a single DVI cable, rather than a dual one, which would explain the reduced resolution. Does anyone have any experience with an issue like this? What can I do to make full use of my new monitor? (Possibly) Relevant Information: There is no DVI port on the laptop itself, but one is provided via the dock. The laptop and dock both provide a DisplayPort jack, but I have been unable to get this working on either w/ the monitor. I did have the nouveau driver installed when I installed the nvidia proprietary driver, but have since removed it (no change in the monitor situation when I removed it). The 27" reports a max resolution of 1680x1050. Thanks, Joe

  • Monitoring Bandwidth Usage (Per Internal IP) - Cisco ASA 5505

    - by Joseph Sturtevant
    I manage a small network with a Cisco ASA 5505 and a shared DSL connection. I would like to be able monitor the bandwidth usage of the various users/devices on my network (by IP). Can I do that using the ASA? Has anyone got this working? What is the best way to do this? Some Ideas I Have Seen Online: SNMP with a tool like Cacti Does this give per IP usage with an ASA or just overall usage? Netflow with a tool like ntop Couldn't get this to work. It seems that the Netflows sent by ASA are not exactly standard. Ntop receives them, but doesn't seem to know what do with them.

  • Adding tables to a herd in bucardo

    - by Joseph the Dreamer
    Forgive my ignorance, I am a JS programmer given the task to do DB replication using bucardo. I understand the concept of how bucardo works, but setting it up is a bit confusing. The set-up is: Lubuntu Linux Two databases test_master and test_slave, using PostgreSQL Each DB has a table named test, containing 2 columns: id (PK) and test (int) I use pgAdmin3 I have already added them to bucardo's list of databases and added all tables. Table: public.test DB: test_slave PK: id (int4) Table: public.test DB: test_master PK: id (int4) As you see, due to the fact that the DBs are identical, even the schema names are identical. So when I do: bucardo_ctl add herd sample_herd public.test Ok, so it got added to the herd. But this command gets confused which database public.test comes from. So when I add a sync: $ bucardo_ctl add sync sample_sync source=sample_herd targetdb=test_slave type=fullcopy Failed to add sync: DBD::Pg::st execute failed: ERROR: Source and target databases cannot be the same: test_slave at line 118. at line 30. CONTEXT: PL/Perl function "validate_sync" at /usr/bin/bucardo_ctl line 3362. What does it mean that source and target cannot be the same? If it got confused as to which public.test to use as source, how do I differentiate?

  • Certain banking pages not loading

    - by Joseph Lee
    For some unknown reason, I am suddenly unable to access my accounts at several banking and credit sites. I have been a registered user at each site for several years and know I am using the correct user ID and password. Yet, after entering the data, answering security questions, and clicking the submit button, I land on a page with an error message saying their is a technical problem preventing me from accessing my account. On one site, I end up at the sign in page repeatedly. I am never told that my ID/password are incorrect. I believe may be firewall related. Windows firewall was damaged after a recent malware attack. I am now using a third party firewall (Fort Knox). I am not seeing a pop-up indicating sites are blocked or asking me to indicate yes or no. I am using Windows 7 Home Premium. I get the same result regardless of the browser. I switched to Maxthon last night and am getting the same result. This is not happening at other sites. And I am able to access some banking sites normally. This is frustrating because I need to make payments and have gone paperless. Any feedback will be appreciated. ---- Joe ----

  • Setting up multiple servers for one domain

    - by Joseph Torraca
    So I am starting up a new website and I was wondering how to set up 5 servers to host the site. I have already purchased 5 Apple XServes, one will be used as a test server and the other 4 will be for the live site. So I have read some website on the internet and they all reference using one server and installing software onto it and have that server do the load balancing. I have also read that you could use a hardware, rack-mounted system and plug the servers into that. The load balancer would then distribute the load. So I have a few questions about each: 1) How do you set up the software version and have the other servers as "slaves" and have one "master" to direct traffic? 2) Which of the two options above are more reliable, and better suited for a startup that doesn't have many users per month, yet(hopefully)? 3) Is there a theoretical max limit of servers that can be connected to a software load balancing system? Note: Obviously this will change from software to software, but in terms of the server being able to handle it? 4) In your own opinion, what are you using for your sites? Have you had any problems setting up that system or operating it once its running? Are there any things you would stay away from if you had to start over? 5) I also purchased a Apple RAID system, so if you are familiar with it, is there any way to connect it to multiple Xserves so they all serve the same data? I'm a little confused on this, so thanks for all your help and being patient with me. Note: Take it easy on me, I am learning this as I go along, so I may have used terms incorrectly or explained things that don't really make sense. Sorry. P.S. If you need me to supply the specs on the servers to determine which system makes the most sense, I can post them for you.

  • apache2: Could not reliably determine the server's fully qualified domain name

    I've never encountered this error before. And secondly I'd like to know how you folks debug your apache configurations. apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName In my Virtual Host configuration I do have these lines: ServerName example.com ServerAlias www.example.com (of course it has my actual info in there) So I guess my question is, why wouldn’t apache be able to determine my fully qualified domain name?

  • Have a service start on startup with Ubuntu

    - by Joseph Silvashy
    I'm not clear on how to start a service when the server boots, I read on some of the other questions asked about adding the script to /etc/init.d, but It's just one line that I need to execute in the commandline: sudo /etc/init.d/avahi-daemon restart But I have a few issues with this, firstly, I apparently need to use sudo, and it gives me the following: ngl-server-01:~% sudo /etc/init.d/avahi-daemon start Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service avahi-daemon start Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility, e.g. start avahi-daemon But when I try just avahi-daemon start I get: Too many arguments Why is this? and how would you start this service?

  • Only show hidden files in certain directories

    On a Unix system (or more specifically on OS X) is it possible to show hidden files in only some directories? For example as a developer I want to see the hidden files in my Rails projects but not on my desktop as well. I guess I'm just tired of seeing all these .DS_Store and .trashes files swimming around, any remedies not directly related are welcome too!
