  • xset: unable to open display

    - by user287878
    for the longest time after about 5 minutes my screen would blank out. Now the screen will go blank after 5 minutes but then 2 seconds after that it will light up white and keep the laptop backlighting on. I didnt change any settings to my knowledge it just happened randomly after powering it on one day and has occurred since then. I wish to resort back to blanking the screen out completely since i leave this computer on all the time and its hard to sleep with a huge white light all the time. "xset dpms force off" just yeilds me ---- xset: unable to open display ""

  • Limiting what resumes computer from suspend

    - by user1399195
    I'm having a ton of trouble getting Suspend to work with my laptop. I want to start using Ubuntu but this is a pretty important aspect since I take my laptop with me everywhere. Anyways, I wanted to narrow down the possible problem with my laptop. What happens is that when I suspend my computer, within seconds, it just boots back up. I have changed /proc/acpi/wakeup to where everything is disabled but that did nothing. Is there a way where I can disable every feature from waking up the laptop except the power button?

  • How to know which protocol is used in data transfer and inspect that data?

    - by user37880
    I've a .net application for windows. This application transfers a lot of data to and from a particular server on a fix port no 8888. I tried 'Tcpview' but couldn't figure out anything useful. I only figured that it uses 'tcp' connection. Is there a way to know which protocol is used for data transfer (I think port no 8888 is not specific port so not helpful)? How exactly my machine makes connection to this server? Is it telnet/http etc or what? How can I inspect the actual data which is being transferred? If data is encrypted, is it possible to know encryption method on client side (without reverse engineering)? Thanks.

  • What's a standard productive vs total office hours ratio? [migrated]

    - by marianov
    So it goes like this: we are keeping track of tasks using Redmine. We log time spent doing tasks, but at the end of the week if we add up all the time spent at those tasks there is no way a person has spent 40hs working. I think that's correct because offices have overhead (reading emails, politics, coffee, distractions). What would be a normal productive time vs total time spent ratio? Other areas in the organization just measure time spent in the office (with the rfid badges that open the door) but we don't like that approach and we are trying to convince Auditing to measure us using redmine instead.

  • no more network connection Ubuntu 12.04 Server

    - by gerpol
    Since yesterday my 12.04 web server refuses to connect to the Internet. Also when I boot I'm seeing the "waiting for network config" message. After logging in I'm getting an error about the packages. Error text: E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_precise-updates_universe_i18n_Translation-en, E:The package lists or status file could not be parsed or opened. This is a production web server so I really could use some help with enabling the network connection again.

  • How would you manage development between many Staging branches?

    - by Trip
    We have a Staging Branch. then we came out with a Beta branch for users to move whenever they wanted to from old Production branch to the new features. Our plan seemed simple, we test on Staging, when items get QA'd, they get cherry-picked and deploy to Beta. Here's the problem! A bug will discreetly make its way on to Beta, and since Beta is a production environment, it needs fixes fast and accurate. But not all the QA's got done. Enter Git hell.. So I find a problem on Beta. No sweat, its already been fixed on Staging, but when I go to cherry-pick the item over, Beta barely has any of the other pre-requisites of code to implement this small change. Now Beta has a little here and a little there, and I can't imagine it as a code base being as stable as Staging. What's more, is I'm dealing with some insane Git conflicts, and having to monkey patch a bunch of things to make up for what Beta hasn't caught up with Staging. Can someone polite or non-polite terms, tell me what we're doing wrong here as far as assembling this project? Any awesome recommendations or workarounds or alternatives to the system we came up with?

  • Disk drive won't let go of password prompt at bootup?

    - by user54003
    I had a hacker intrude into my system, at the time it was obvious, so I reinstalled. However, I am left with what appears to be a fatal problem as far as one of my disk drives goes. When I install that drive in my system, a prompt comes up for the disk password, and what it is asking for is a root password. The disk works otherwise normally but despite all my efforts, I have not been able to fix this disk. I have gotten the operating system parted magic and done the most extreme clean up available, the internal one which sends a signal to the disk electronics which runs a built in clean up program. Darik's boot and nuke, I've tried them all but I can't seem to remove this with anything in the Linux line. Does anyone have any suggestions? I've run gparted, created a Sun, an Apple and various other schemes to partition the disk, all to no avail. Can anyone help?

  • How much work advanced level developer performs during the day, week or month? [closed]

    - by user1866998
    I have never worked in the large IT-corporations, and it is very interesting for me of how much work advanced level developer has to perform during the period of, for example, a week or month. So what is the average performance and intensity of work of such a high class professionals expected by employers? I understand that the question is a bit abstract and the result depends on the set of different factors in every particular case, but I think that it is possibly to do the average and rough estimation or to give an example.

  • Replacement for Picasa [closed]

    - by January
    Possible Duplicate: What is the best alternative to Picasa? I use Picasa not because it is a great photo manager -- it's not, the manager is "sort of OK" for my taste. However, it combines a passable photo manager with a good "quick and dirty" image editor. It has the basic functions like cropping, resizing, contrast and color adjustment, and the one great feature -- "I'm feeling lucky" button, that works in 90% of the cases. Also, from time to time, I use one or two of the effects (like saturation or sharpening). GIMP is great and I use it on a regular basis, but in most cases I just want to go quickly through the photographs of my kids birthday and make them more presentable without much fuss. I'm looking for a native, open source replacement, something that would not miss the editing capabilities of Picasa and would allow me to quickly go through a collection of photographs and make basic edits. A function similar to "I'm feeling lucky" (automatic adjustment of contrast, color and brightness) would be most welcome. EDIT: Yes, I have already tried a number of alternatives, if it is necessary I can produce a detailed list here, along with the problems I found. I'm posting that question because I hope to see a new name.

  • Variable-step update() in game loop is falling behind, how can I get around this?

    - by ThatsGobbles
    I'm working on a minimal game engine for my next game. I'm using the delta update method like shown: void update(double delta) { // Update code that uses `delta` goes here } I have a deep hierarchy of updatable objects, with a root updatable that contains several updatables, each of which contains more updatables, etc. Normally I'd just iterate through each of the root's children and update each one, which would then do the same for its children, and so on. However, passing a fixed value of delta to the root means that by the time the leaf updatables are reached, it's been longer since delta seconds that have elapsed. This is causing noticable desyncing in my game, and time synchronization is very important in my case (I'm working on a rhythm game). Any ideas on how I should tackle this? I've considered using StopWatches and a global readable timer, but any advice would be helpful. I'm also open to moving to fixed timesteps as opposed to variable.

    - by Alan
    Back when I had windows 7, I cloned my internal hard drive to an enclosed external usb hard drive. I then formatted my internal hard drive and installed ubuntu 11.10 as my only OS. How do I migrate my files, pics, mp3's, and etc off the external drive and back to my internal drive which now only has ubuntu on it. (and why is this process not made easier?) I have tried logging in as the root user but I cannot find the external device. I have downloaded several different apps to manage files, usb sticks and etc. PLEASE HELP!!!

  • Working hours for a newbie

    - by martani_net
    This is not a very related software / hardware question, but it's too related to the Tech world. I started a work 3 months before, and I am about to finish this week, and my boss asked me to do a planning of what I've done so far, I think this is totally ok, but he is asking for what I did each day with the hours I spent in these days. This is a sample of what I sent him M T W T F week 29/06 to 03/07 compréhension et analyse du problématique * * architecture de l'application * * * which translates to first task, I spent Monday + Tuesday on, and the last W, T, and Friday. What he is asking for, is what I've done in each day, with the timing I spent on (obviously, I don't think I remember, and because for a programmer, there are no sequence tasks, I mean I change code in a class, then change it in another to fit with the new one and so far) So my question is: is what he asking normal? and if so how can I detail the planning for the 3 months. [update] I used the email account we use to test our software with the extern servers, and I got a good view of what I was doing in every day :), a generic view but it helped too much (PS: The boss doesn't know anything about programming, for him, it's like writing lines and get results back nothing more )

  • Laptop Hibernates after adapter is unplugged

    - by SpyrosR
    Hello i am experiencing a strange problem under Ubuntu 12.04. If I unplug the charger while my laptop is on,i don't see any messages but my laptop goes straight into a suspend or hibernate mode and it's a real pain to get it stable again afterwards. It always suspends (or hibernates) It always takes 2 attempts to restart it (press power button, it starts and it hibernates again, press power button and it starts and stays on) It sometimes has an effect on the wireless which doesn't come back clean and i either have to switch the wireless on and off a couple of times. I sometimes have to restart the laptop totally Is anyone else experiencing the same issues and if yes,is there any solution? Thank you in advance.

  • Game Database Connectivity Java

    - by The Kraken
    I'm developing a simple multi-player puzzle game in Java. Both players should be able to view the same game board on his own computer. Then, when one player makes an action in the game (ex. drags an object onto a coordinate space), the game's view should update automatically on the other computer's game screen. I'd like all this to happen over the internet, not requiring both computers to be on the same LAN connection. If I need to use SQL/PHP to accomplish this, I'm unsure how to design the database to accomplish something as simple as the following: Player A drags element onscreen Game sends coordinates of element to database/server Player B's computer detects a change to an item in the database Player B's computer grabs the coordinates of Player A's item Player B's machine draws onscreen elements at the received coordinates Could somebody point me in the right direction?
