  • Running Ubuntu on Toshiba L630

    - by Toshibalin
    After suffering with the following error while trying to install Ubuntu onto my Toshiba L630 (kernel_thread_helper+0x0 0x10). I bypassed the error and managed to install the OS by going going into the "installation setup menu"( by pressing f6 while booting from my Ubuntu Installation CD) and assigning "acpi = off". I believe this fixes the problem because it stops the laptop doing checks that aren't compatible with the software. However, now that I have Ubuntu installed, I cannot run the bloody thing because I have no way of choosing "acpi=off" before booting Ubuntu. I guess this is a pretty broad question but I'm going to ask it anyways. Has anyone managed to find a version of linux that works on an L630 without any errors? If not, Is there a way to choose acpi=off before booting? Maybe by adding a line to the grub? Also, does anybody think I'm wasting my time? I read somewhere that toshiba laptops don't work well with linux. So if there isn't a fix for this I would appreciate being alerted about this. Cheers

  • What is the best time to set the IP address for a server headed to a server colocation facility?

    - by jim_m_somewhere
    What is the best time to set the IP address for a server? I have a server that I am going to install the OS on and then I am going to send it to a server colocation facility. The server is going to have Internet facing services (www, email, etc.) I can set up a "fake" IP address during install (by fake I mean private as in RFC 1918) and change the "fake" IPs to the real IPs once I set up the colocation service. The other option is to set up the colocation service...wait for them to give me the "real" IPs and use them during the OS install. The ramification are that...if I use "fake" IPs during install...I will have to wait before I set up things like SSL certs. If I wait for IPs from the colocation provider...then I can set up SSL certs that use the "correct" (as in "real") IP addresses...no changes to the certs until they expire. Do the "gotchas" of changing an IP address on a server outweigh the benefits of a quick install? The other danger with using "fake" IPs is that I could make a mistake when I go through the various files to change the IP address to the "live" IP address. Server OS: CentOS 6.2 or CentOS 6.3, 64 bit. Apps: Apache 2.4.X httpd, MySQL 5.X (will eventually use replication)

  • Easily Plotting Multiple Data Series in Excel

    - by John
    I really need help figuring out how to speed up graphing multiple series on a graph. I have seperate devices that give monthly readings for several variables like pressure, temperature, and salinity. Each of these variables is going to be its own graph with devices being the series. My x-axis is going to be the dates that these values were taken. The problem is that it takes ages to do this for each spreadsheet since I have monthly dates from 1950 up to the present and I have about 50 devices in each spreadsheet. I also have graphs for calculated values that are in columns next to them. Each of these devices is going to become a data series in the graph. E.g. In one of my graphs I have all the pressures from the devices and each of the data series' names is the name of the device. I want a fast way to do this. Doing this manually is taking a very long time. Please help! Is there any easier way to do this? It is consistent and the dates all line up. I am just repeating the same clicks over and over again Thank you!

  • Is there a way to measure wifi traffic on a network from a client?

    - by millimoose
    Is there some way (preferrably one that comes with an existing tool) to measure the traffic going through the whole WiFi network from a computer connected to it? (That is, not from the AP or something between the modem and AP.) My situation is this: a few months back, the internet connection at my parent's place got really sluggish and laggy. (Lag spikes that cause page loads to time out etc, connections plain getting lost and dropping packets forever.) It's impossible to get mom's husband to do anything about this because he brushes this off with something like "just tell your sister to turn off torrents". Unfortunately the WiFi router's firmware doesn't do traffic logging. I'm not going to risk bricking it to put WRT on it; nor am I keen on rewiring the network to add a proxy to analyse the traffic. (I'm one of those people that make computers break just by looking at them, except machines I own.) I'd like to be able to find out roughly how much data is going over the air here while all the LAN wires are out of the router, all the computers accused of torrenting are off, etc. The idea is to either show that: Even if everything but my macbook is turned off, something is congesting the network. The husband is a systems developer and has a whole lot of mysterious hardware that's not to be touched around, one of them might be culprit. There is barely any traffic on the network, but the internet is still sluggish. Meaning this is likely a problem the ISP should solve. (Some hardware of theirs being glitchy, someone on an aggregated line hogging it constantly...) The network is encrypted, but I can temporarily set it to open for the sake of finding this out. So, in conclusion? Can this be done? Or is there some alternative way I could try to diagnose the problem?

  • Programmers - I have a question for you.

    - by jens
    My boyfriend does coding (Rails/C?/PHP) for a job and I don't know what he would appreciate on our first anniversary. Does anyone have any ideas? Yes, he's stereotypical geek, but I'd rather not give a pack of Bawls for an anniversary gift. He dislikes going anywhere, so "experiences" like going to an event are out. Maybe I should just have a giant LAN party in the house.

  • Why is the HttpContext.Cache count always zero?

    - by jjr2527
    I set up a few pages with OutputCache profiles and confirmed that they are being cached by using multiple browsers and requests to retrieve the page with a timestamp which matched across all requests. When I try to enumerate the HttpContect.Cache it is always empty. Any ideas what is going on here or where I should be going for this information instead?

  • General advice about scaling on QGraphicsView/QGraphicsScene

    - by onurozcelik
    Hi, In my project I am using QGraphicsView/QGraphicsScene stuff. On my scene there will be regions that contains 2D graphics. Region count will be limited(Lets say 20) Users can choose to display one or more regions. If user choose to display one region I am going to show one region on scene If user choose to display n regions I am going to show n regions on scene I need a scaling logic to fit n regions on same scene. How can I achieve this?

  • Is the Scala 2.8 collections library a case of "the longest suicide note in history" ?

    - by oxbow_lakes
    First note the inflammatory subject title is a quotation made about the manifesto of a UK political party in the early 1980s. This question is subjective but it is a genuine question, I've made it CW and I'd like some opinions on the matter. Despite whatever my wife and coworkers keep telling me, I don't think I'm an idiot: I have a good degree in mathematics from the University of Oxford and I've been programming commercially for almost 12 years and in Scala for about a year (also commercially). I have just started to look at the Scala collections library re-implementation which is coming in the imminent 2.8 release. Those familiar with the library from 2.7 will notice that the library, from a usage perspective, has changed little. For example... > List("Paris", "London").map(_.length) res0: List[Int] List(5, 6) ...would work in either versions. The library is eminently useable: in fact it's fantastic. However, those previously unfamiliar with Scala and poking around to get a feel for the language now have to make sense of method signatures like: def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That For such simple functionality, this is a daunting signature and one which I find myself struggling to understand. Not that I think Scala was ever likely to be the next Java (or /C/C++/C#) - I don't believe its creators were aiming it at that market - but I think it is/was certainly feasible for Scala to become the next Ruby or Python (i.e. to gain a significant commercial user-base) Is this going to put people off coming to Scala? Is this going to give Scala a bad name in the commercial world as an academic plaything that only dedicated PhD students can understand? Are CTOs and heads of software going to get scared off? Was the library re-design a sensible idea? If you're using Scala commercially, are you worried about this? Are you planning to adopt 2.8 immediately or wait to see what happens? Steve Yegge once attacked Scala (mistakenly in my opinion) for what he saw as its overcomplicated type-system. I worry that someone is going to have a field day spreading fud with this API (similarly to how Josh Bloch scared the JCP out of adding closures to Java). Note - I should be clear that, whilst I believe that Josh Bloch was influential in the rejection of the BGGA closures proposal, I don't ascribe this to anything other than his honestly-held beliefs that the proposal represented a mistake.

  • does it makes sense to use int instead of char or nvarchar for a discriminator column if I'm using i

    - by Omu
    I have something like this: create table account ( id int identity(1,1) primary key, usertype char(1) check(usertype in ('a', 'b')) not null, unique(id, usertype) ) create table auser ( id int primary key, usertype char(1) check(usertype = 'a') not null, foreign key (id, usertype) references account(id, usertype) ) create table buser ( ... same just with b ) the question is: if I'm going to use int instead of char(1), does it going to work faster/better ?

  • Override variables while testing a standalone Perl script

    - by BrianH
    There is a Perl script in our environment that I now need to maintain. It is full of bad practices, including using (and re-using) global variables throughout the script. Before I start making changes to the script, I was going to try to write some test scripts so I can have a good regression base. To do this, I was going to use a method described on this page. I was starting by writing tests for a single subroutine. I put this line somewhat near the top of the script I am testing: return 1 if ( caller() ); That way, in my test script, I can require 'script_to_test.pl'; and it won't execute the whole script. The first subroutine I was going to test makes a lot of use of global variables that are set throughout the script. My thought was to try to override these variables in my test script, something like this: require_ok('script_to_test.pl'); $var_from_other_script = 'Override Value'; ok( sub_from_other_script() ); Unfortunately (for me), the script I am testing has a massive "my" block at the top, where it declares all variables used in the script. This prevents my test script from seeing/changing the variables in the script I'm running tests against. I've played with Exporter, Test::Mock..., and some other modules, but it looks like if I want to be able to change any variables I am going to have to modify the other script in some fashion. My goal is to not change the other script, but to get some good tests running so when I do start changing the other script, I can make sure I didn't break anything. The script is about 10,000 lines (3,000 of them in the main block), so I'm afraid that if I start changing things, I will affect other parts of the code, so having a good test suite would help. Is this possible? Can a calling script modify variables in another script declared with "my"? And please don't jump in with answers like, "Just re-write the script from scratch", etc. That may be the best solution, but it doesn't answer my question, and we don't have the time/resources for a re-write.

    I want to build a social network, with some of the users being able to put up some stuff up for sale. So basically, a social network + multiple sellers e-commerce. What is the best technology solution for that? I was thinking of going Rails route, using CommunityEngine and ActiveMerchant. Another option is going PHP and using something like X-Cart, which already has multiple sellers interface. Any recommendations? Thanks!

  • Best Project Template to use for Classic Web Service

    I'm going to create a new PayPal project. Should I just create a regular Class Library project then add the reference to the WSDL? We are not using WCF. I just want to know what the best project type / template I should use if I'm going to share this project with lets say another WAP web project. I simply want to create wrappers for some of the WSDL that we'll be using in part of the PayPal API.

  • Webcam service for a website: user to user, directly, is it possible?

    - by user293224
    Hello everyone I wonder wether on a website like chatroulette for example, the streaming video is going directly from user to user or wether it is going through a server. In other words I wonder wether it is possible to offer a webcam service on a website, so that the streaming video goes directly from user to user, without overloading the system. If it is possible, what technology makes it possible? Flash? Thank you ;)
