  • is it necessary to format windows XP OS to do partitioning for Ubuntu, and how do I do it properly to then install Ubuntu from disk

    - by Brother V
    is it necessary to format windows XP OS to do partitioning for Ubuntu, and how do I do it properly to then install Ubuntu 10.10 from disk, and would it work from 10.10 to get 12.04 updates? Thank you all; for being, for being soooo forth-giving and for all you ever will to be. I endeavor to support and be of such torch-carrying also, and Am honored by the beautious examples of the people in these forums.

  • How to set up multiple GPUs (12.04)?

    - by Brother Erryn
    I have two GPUs: one Intel i915 integrated, and one NVIDIA 560 Ti. This is NOT a hybrid setup, nor a laptop. In Windows 7, each card is connected to a different monitor, with the NVIDIA doing any "heavy lifting". For the life of me I cannot get Ubuntu to recognize the i915, but when logging off or rebooting, the shutdown actually appears on the i915. lshw lists both. I'm running the "current" NVIDIA drivers (not the experimental), but Displays calls its monitor a "Laptop". Is this even possible under Ubuntu? The only things that even looked like potential solutions were for laptop hybrid setups and used Bumblebee, but that doesn't seem to apply here.

  • C Programming Language and UNIX Pioneer Passes Away

    According to a statement given to the New York Times by Ritchie's brother Bill, Dennis Ritchie was living alone at his home in Berkeley Heights, New Jersey, prior to his death. Richie's health had reportedly deteriorated, and his last years were made difficult by the after effects of treatments for prostate cancer and heart disease. In addition to his brother Bill, Ritchie is survived by his sister Lynn and his other brother John. Dennis Ritchie was born in Bronxville, New York, in 1941. His father was an engineer with Bell Labs and his mother was a homemaker. His family eventually moved...

  • Small store infrastructure - where to begin?

    - by KevinM1
    It looks like my older brother is about to change jobs - from lawyer to shooting range proprietor - and since I'm the family 'computer guy' I have the task of coming up with and setting up the in-store equipment. Only problem, I don't know how to start or where to look. I'm a web programmer, not an IT specialist. To that end, I figured I should ask the pros. Users: 3 (myself, my brother, and his business partner) Equipment: 1 Windows (likely 7) desktop for POS software, 1 Windows desktop/laptop for backroom use (bookkeeping, etc.) Other: ?? I'm looking for a reliable and, well, idiot-proof way to handle backups. Neither my brother nor his business partner are tech savvy (A web browser, email, MS Word and Excel are about the extent of their knowledge), so I need something they can handle. On-site would be preferable to off-site, given my brother's hesitance to have sensitive business data be handled by an outside source. I'm also looking for a small on-site server. I estimate that, at most, only 2-3 users will need access. A linux solution would keep costs down, but I'm concerned about Windows <- linux interoperability. Would the store security cameras' storage be handled by the security company, or would we have to stream that data to our own server? I know from my own experience with personal security that the company gives/loans a recording device to the home owner, but I'm not sure about business security. I know this sounds like a shopping list, and it's pretty vague. I wish I could give more detail, but between my own ignorance and things not being 100% nailed down on the business end, I'm a bit stuck. At the very least I'd like a nudge - links on a place to start, what to look for, things I need to think about, etc. - for this endeavor. Thanks.

  • re-direct SSL pages using header statement based on port

    - by bob's your brother
    I found this in the header.php file of a e-commerce site. Is this better done in a .htaccess file. Also what would happen to any post parameters that get caught in the header statement. // flip between secure and non-secure pages $uri = $_SERVER['REQUEST_URI']; // move to secure SSL pages if required if (substr($uri,1,12) == "registration") { if($_SERVER['SERVER_PORT'] != 443) { header("HTTP/1.1 301 Moved Permanently"); header("Location: https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); exit(); } } // otherwise us regular non-SSL pages else { if($_SERVER['SERVER_PORT'] == 443) { header("HTTP/1.1 301 Moved Permanently"); header("Location: http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); exit(); } }

  • spoolsv.exe consumes all CPU and RAM resources

    - by pcampbell
    Consider a Windows 7 x64 installation with 2 printers installed. The system has 8GB installed RAM. One printer is a Brother laser MFC-8220 Printer via TCP/IP, and the other is a CutePDF printer. Problem: the spoolsv.exe regularly eats obscene amount of memory and CPU when the machine is idle. Usually the device is powered off. Turning it on has no effect on the RAM or CPU usage. The first consideration was that perhaps a print job has previously been sent to the Brother, but the queues are empty, and no jobs are waiting. These screenshots do not show, but regularly the spoolsv service will consume all 8GB and climb to use 95-100% of the CPU. The two printers - a Brother and the CutePDF printer both have 0 documents in their respective queues. Question: what measures can I take to ensure the spoolsv.exe doesn't consume inappropriate amounts of CPU and RAM?

  • How to debug xsane "no devices available" error on 64 bit Ubuntu 10.04

    - by BD at Rivenhill
    I have a Brother MFC-J615W printer/scanner and I wish to use the scanning feature across a network with a computer running 64-bit Ubuntu 10.04. I have installed the drivers from the Brother website and followed all of the instructions, and printing works fine, but xsane (installed from repositories) produces a popup with the message "no devices available" on startup. I recently had success with a similar approach when installing drivers for a Brother MFC-495CW on 32-bit Unbuntu 9.10, so I am aware of issues such as requiring root access if the driver permissions are not set correctly, but running xsane as root does not solve this problem. Are there any tools available to debug this problem further or does anyone have advice on how to proceed?

  • PHP 5.3: Late static binding doesn't work for properties when defined in parent class while missing in child class

    - by DavidPesta
    Take a look at this example, and notice the outputs indicated. <?php class Mommy { protected static $_data = "Mommy Data"; public static function init( $data ) { static::$_data = $data; } public static function showData() { echo static::$_data . "<br>"; } } class Brother extends Mommy { } class Sister extends Mommy { } Brother::init( "Brother Data" ); Sister::init( "Sister Data" ); Brother::showData(); // Outputs: Sister Data Sister::showData(); // Outputs: Sister Data ?> My understanding was that using the static keyword would refer to the child class, but apparently it magically applies to the parent class whenever it is missing from the child class. (This is kind of a dangerous behavior for PHP, more on that explained below.) I have the following two things in mind for why I want to do this: I don't want the redundancy of defining all of the properties in all of the child classes. I want properties to be defined as defaults in the parent class and I want the child class definition to be able to override these properties wherever needed. The child class needs to exclude properties whenever the defaults are intended, which is why I don't define the properties in the child classes in the above example. However, if we are wanting to override a property at runtime (via the init method), it will override it for the parent class! From that point forward, child classes initialized earlier (as in the case of Brother) unexpectedly change on you. Apparently this is a result of child classes not having their own copy of the static property whenever it isn't explicitly defined inside of the child class--but instead of throwing an error it switches behavior of static to access the parent. Therefore, is there some way that the parent class could dynamically create a property that belongs to the child class without it appearing inside of the child class definition? That way the child class could have its own copy of the static property and the static keyword can refer to it properly, and it can be written to take into account parent property defaults. Or is there some other solution, good, bad, or ugly?

  • Class design issue

    - by user2865206
    I'm new to OOP and a lot of times I become stumped in situations similar to this example: Task: Generate an XML document that contains information about a person. Assume the information is readily available in a database. Here is an example of the structure: <Person> <Name>John Doe</Name> <Age>21</Age> <Address> <Street>100 Main St.</Street> <City>Sylvania</City> <State>OH</State> </Address> <Relatives> <Parents> <Mother> <Name>Jane Doe</Name> </Mother> <Father> <Name>John Doe Sr.</Name> </Father> </Parents> <Siblings> <Brother> <Name>Jeff Doe</Name> </Brother> <Brother> <Name>Steven Doe</Name> </Brother> </Siblings> </Relatives> </Person> Ok lets create a class for each tag (ie: Person, Name, Age, Address) Lets assume each class is only responsible for itself and the elements directly contained Each class will know (have defined by default) the classes that are directly contained within them Each class will have a process() function that will add itself and its childeren to the XML document we are creating When a child is drawn, as in the previous line, we will have them call process() as well Now we are in a recursive loop where each object draws their childeren until all are drawn But what if only some of the tags need to be drawn, and the rest are optional? Some are optional based on if the data exists (if we have it, we must draw it), and some are optional based on the preferences of the user generating the document How do we make sure each object has the data it needs to draw itself and it's childeren? We can pass down a massive array through every object, but that seems shitty doesnt it? We could have each object query the database for it, but thats a lot of queries, and how does it know what it's query is? What if we want to get rid of a tag later? There is no way to reference them. I've been thinking about this for 20 hours now. I feel like I am misunderstanding a design principle or am just approaching this all wrong. How would you go about programming something like this? I suppose this problem could apply to any senario where there are classes that create other classes, but the classes created need information to run. How do I get the information to them in a way that doesn't seem fucky? Thanks for all of your time, this has been kicking my ass.

  • Make 2 links same height in columns?

    - by brother
    I have a setup where i have a unordered list on a page with x <li><a href="#">Link text</a></li>. They are via CSS set to 50% width each, so that i have 2 items on each line. My problem is that 2 links on one line, can vary in height as they have different link text. My question is; how can i, via jQuery, set the same height for each (the a is styles with a border bottom, so it would look best if they alined) on the same line? But not all in the sections should have the same height, only on a "pr line" basis. Hope it makes sence :)

  • Would you recommend Head First Programming for someone new?

    - by Sergio
    My brother is just starting out college. He's studying the same thing I am here in Bolivia; Systems Engineer which is the equivalent of what a CS degree is in the US. Being his big brother and a programmer myself I really want to guide him and give him the right material to learn and become good at programming. My motives are selfish I admit, I want him to become really good so he can teach me things in the future. :) After poking around the web, I found Head First Programming. This book seems to teach the fundamentals of programming, using Python as the language. Would you recommend this book as his first book ever? Would learning Python as his first language stunt him somehow? What are your thoughts and suggestions? Thanks!

  • Printing takes forever and gives pixelated prints

    - by kelvinsong
    I have a Brother HL-3070CW printer, which has some serious issues. Printing takes an abnormally long time, and if the file has anything more than text in it, it becomes horribly aliased and pixelated. The printer also sometimes complains about running out of memory. This problem has appeared on and off throughout various Ubuntu releases, and can sometimes be worked around by saving a file in Postscript through Evince, and printing the PS file in Evince. I tried to install drivers from the Brother website, but it gives an error "dependency not satisfiable: hl3070cwlpr" Help, I'm wasting a huge amount of paper and ink(not to mention time) reprinting pages over and over again in trial and error.

  • Should a new programmer nowadays start with C/C++ or OOP language? [closed]

    - by deviDave
    I've been a programmer for 15+ years. In my time, we all started with C or C++ and then moved to C# or Java. At that time it was a usual practice. Now, my brother wants to follow my steps and I am not sure what advice to give him. So, I am asking the community for an opinion. Should nowadays new programmer with zero programming knowledge start with functional languages (C, C++, etc.) or he should start directly with OOP languages (Java, C#, etc.)? The reply should be considered in the context of my brother's future assignments. He will mainly work on Java mobile applications as well as ASP.NET web apps. He will have to touch with desktop apps, low level programming, drivers, etc. This is the reason I am not sure if he should ever need to learn functional languages.

  • Should I install ia32-libs or lib32stdc++ or can I just use --force-all for 32-bit printer driver

    - by William
    I got a Brother printer MFC class. The brother website only provides 32-bit drivers but I installed 64-bit Ubuntu. It says I need to install "ia32-libs" or "lib32stdc++" to install the 32-bit drivers onto 64-bit Ubuntu. Elsewhere I've read that I don't need to install these packages, I can just use --force-all when installing, but I don't know of the accuracy of this information. My questions: 1) do I HAVE to install "ia32-libs" or "lib32stdc++" or can I use --force-all to make 32-bit drivers install on 64-bit ubuntu? 2) if I do have to install "ia32-libs" or "lib32stdc++", which should I install? Which is better, which is recommended by ubuntu experts?

  • Server 2003 Remote Desktop loses its virtual printer image of the local printer

    - by Charles Hart
    Server 2003 Remote Desktop provides service to stores served by several ISPs. The server loses its virtual printer image of the local printer (as seen from the remote store site) and a copy of the original local printer appears on the local computer with a different driver without notice. Specifically: A remote desktop session is opened on a local computer that has a Brother HL2140 USB printer connected and the associated software installed with a correct driver shown under the “advanced” button. The server has the same Brother software and driver. An application that is running on the server attempts to print on the local printer connected to the local computer running Vista Pro or XP Pro. Either it works correctly (Good) or it does not print (Bad) or it prints on another Local Printer connected to another local computer logged into the server (Bad and Odd). When it doesn’t print (or prints somewhere else) we ask the customer to look for the (virtual) printer using the Remote desktop view of the server and the printer is gone. Then we ask the customer to look at the printers folder in the local computer. There are several possibilities: The printer is there, but the driver is mysteriously changed in the drop down to MDX something; we have the customer select the other (proper) Brother driver, and all is well again, as now after the change, the virtual printer in the server (which now matches the local printer) appears again, and so printing can resume. A “copy” of the printer mysteriously appears in the local printer’s folder and after we delete it the virtual printer in the server appears again and so printing can resume. Note that in both case 1 and 2, the server sometimes sends the print job elsewhere, to some other local computer. Meanwhile in the log file, endless errors are reported and the server eventually crashes, sometimes twice a day. I’m puzzled what changes the local printer driver and I’m puzzled what loads the copy 2 or copy 3 of the printer in the local printer folder. This entire description randomly occurs on any of 40+ local computers in eight different locations in different ISPs, all sharing one Domain.

  • Printing special / extended characters on web page - Firefox or printer issue?

    - by edmicman
    My dad brought this to my attention and I'm looking into it, but thought I'd post here and see if anyone has any ideas... He's running Win7, using Firefox and printing to a wireless connected Brother HL-2170W printer. He's got a web page (http://cornandsoybeandigest.com/inputs/fertilizer/applying-nitrogen-after-planting-0512/index.html) that has extended/special characters in it - the funny "a" in Fernandez. The characters show correctly in Firefox on the page. He printed it, and the extended "a" printed as a diamond with a question mark. He says it shows that way in the print preview, too. I pulled up the same page in Ubuntu, Firefox, and it displayed in my print preview and physically printed everything correctly. I just checked on my wife's Win7 PC in Firefox and the print preview looked correct on her system, too. We have a Brother 2040 here. Soooo, my question is, is this possibly a problem in the browser somehow, or the printer driver? I'm leaning towards the printer driver now, but I can't say I've run into this before. Is it a setting somewhere? I just installed this printer for him the other day, using the CD that came with it; I could try updating the driver from Brother's website I guess. Is there anything else I should look at or check? Thanks!

  • Color Profiles in Windows 7 vs. XP

    - by flxkid
    I have a Brother Color Laser Printer and an HP 8150DN. I have a local Windows 7 Pro machine that I do graphics work on. I created a letterhead that when printed from my machine looks dark and rich on either the mono HP or the color Brother laser. I take this same letterhead, and move it onto our network for use by our users which are all on XP. Then they print the same file, it is washed out on either printer. I've confirmed that the printer settings we're using are identical. I've confirmed that its not related to the program or even specifically to the letterhead. I can duplicate this with other files too. I'm down to XP vs Windows 7 being the issue. I'm fairly certain now that color profiles are involved. I have no clue how to fix it though. Any suggestions would be much appreciated.

I made local printers accessible over the RDP. I installed the xp drivers for the Brother printer. So my question is, " Is there a way that I can print from my win7 machine remotely connected to a xp sp3 system"? Or is there no way that I can put the correct drivers on the xp machine to have it redirect to my laptop(win7)
