  • Howto update Preview.app from the command line without loosing focus on OSX ?

    - by snies
    Hello, i want to update Preview.app in the background from the command line without loosing focus of my current window. I know that i can use the following to open/update the view of a file, but than i loose focus to the Preview.app. open -a Preview foo.pdf I guess there might be some clever Apple Script commands to do so but so far i didn't find the right one. Alternatively i would be interested into transfering the focus back to my current app directly after the update. I need this in order to update Preview.app's view of a pdf through a vi autocmd after i update the pdf according to changes in a tex file i am editing. Here is an example of what i want to achive but using Ubuntu and evince.

  • Is there anyway to stop Windows 8 from restarting for an update?

    - by William Hilsum
    My Windows 8 machine is going to restart shortly... I have tried a few techniques such as shutdown /a which is not having much luck. Short of pausing the Windows Update service, is there anyway to stop this restart from happening? ---update--- Looks like the "restart" is all talk and no action! The time has gone and I am presented with this: So, it goes along with the top answer here (which I shall shortly accept) --- update again--- It did reset!!! My battery went critical and it turned itself off, I turned it back on (out of suspend) when it was plugged in, I logged in and the first thing it did was automatically restart - closing my open tabs in Chrome :( Oh well...

  • how to prevent log output from PostgreSQL stored procedure ?

    - by ssc
    I am running a number of PostgreSQL scripts that used to produce excessive log output. I managed to reduce most of the output to an acceptable amount by passing --quiet as parameter to the psql command line client and adding SET client_min_messages='warning'; to the beginning of my SQL scripts. This works fine for most basic statements like SELECT, INSERT, UPDATE, etc.) However, when I call a stored function in a script using e.g. SELECT my_func(my_args);, there is still log output similar to my_func (omitted a long with many '-' here because SF thinks that's a headline) (1 row) The output is useless; it only makes me having to scroll back up a long way after the script has run and also makes it much harder than necessary to spot any relevant error output. How can I get rid of it ?

  • Why is hibernation still used?

    - by Moses
    I've never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I've never truly understood why it's used. With today's technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me when modern technology is considered, but perhaps there are applications that I'm not considering. What was the original purpose behind hibernation, and why do people still use it? Edit: I rescind my comment about hibernation being obsolete, as it obviously has very practical applications to laptops and mobile PCs, considering the power restrictions. I was mostly referring to hibernation being used on a desktop.

    This error is happening to 6 out of 32 computers. I have created a base image from scratch using Ghost Enterprise, but error still shows on the same machines. It happens at the log on prompt and after doing a soft reset the message goes away, but it comes back eventually. -Error message- The Instruction at "0X74eF400e" referenced Memory at "0X00000000" The memory could not be "Written".

  • Reimage several of the same model PC by copying the hard disk

    - by Tim Lehner
    I have several of the same machine (Dell Precision T3500) that originally came with Windows 7 Pro (there is a Windows 7 Pro OA product key sticker on top of each one). These were initially downgraded to XP by a former IT colleague, but are now back in the pool of unused machines. I am looking to format and install Windows 7 Pro on one of them using the latest official Win7 installer ISO with SP1 and then clone the hard drive to the other machines. The questions then, are: Does this even make sense, or is there a better way to do this considering I'm only doing it to 6 machines? Does this jive with MS licensing (we are the original purchaser of the machines, and thus, presumably, the license holder...but I'm no expert)? Is it possible to apply the individual 25-char product keys to the cloned machines after cloning? How far can I go in the config process (installing corporate standard apps and such) before I have to clone to the other machines considering the licensing/key questions?

  • Is it wise for a programmer to move into management?

    - by Desolate Planet
    Many times, a developer has suggested that I become a team leader because I'm motivated, but during my career in the IT industry, I've seen so many people who are great at programming, move into management and they are miserable. I've also seen many managers return to programming stating "I'm a technical person, I like technical problems". If this is such a common thing, why do developers feel compelled to leave the technical domain and move into management? Sure you'll have more money and more control, but if you don't enjoy your work and take your problems out on your tream. Secondly, I've been asked in developer interviews, "Would you consider leading a team?" and I'm always tempted to cite the Peter Principle based on what I've seen. I am interested in furthering myself, but not in the way the company may want i.e "Vice President of department blah". To be honest, I've seen this more often in the corporate world than in small development houses and it's always put me off ever going back to a corporate environment. I just feel that this is becoming more and more the norm and it's impacting team morale and degrading the quality of the work. Question: Based on what I've said, Is it a smart move for a technical person to move into management?

  • Adaptec 2020SA RAID controller Set up in RAID5, one drive went down, can I still get data?

    - by SJaguar13
    I have 6 1tb drives in a RAID5. 1 drive went down. On the RAID was 2 virtual machines that I really need back up and running. The spare drive I have to put in the server is a 1.5tb drive, which exceeds the physical per drive limit of the 2020SA. The drive is found in the disk utility, but it is not found in the array management section. I cannot add the drive to the array to have it rebuild. I have a replacement drive along with some spares on their way from Newegg, but I am still looking at a few days of downtime. Is it possible to use the 5 working drives to get the VMs copied off and on to another server or do I just have to wait for the drives to get here?

  • Open Source Projects for Beginning Coders?

    - by MattDMo
    After working as a molecular biologist at the bench for many years, I lost my job last year and am thinking about a career change. I've been using open-source software and doing Linux system administration since the mid 90s, and have written/improved some small shell/Perl/PHP scripts, and am very comfortable building from source, but never progressed to creating non-trivial programs de novo. I want to move to actually learning real programming skills and contributing back to the community, with the possible eventual goal of getting into bioinformatics as a career in the future. I'm a stay-at-home dad now, so I have some time on my hands. I've done a lot of research on languages, and have settled on Python as my major focus for now. I'm set up on GitHub, but haven't forked anything yet. I've looked around OpenHatch some, but nothing really grabbed me. I've heard the advice to work on what you use/love, but that category is so broad that I'm having trouble finding any one thing to get started on. What are your suggestions for getting started? How do you pick a project that will welcome your (possibly amateurish) help? With a fairly limited skill set, how do you find a request that you can handle? What are common newbie mistakes to avoid? Any other advice?

  • machine crash when connecting to external harddisk

    - by Gnot
    i recently had a problem with my laptop. when i booted up the machine, i would get a SMART failure error message and when i pressed F1 to continue, it would take a very long time to boot and it would come back to the same error message again. thinking that my hard disk was dying, i bought a new hard disk and installed on my laptop and so now my laptop is alright. however i need to recover data from that old hard disk, so i bought an external hard disk case and placed the old hard disk onto the case and connected to my laptop with USB. the first few times when i connected, i could see the files from the old hard disk and managed to copy some files over although it took extremely long to transfer. but now whenever i connect to the old hard disk, after a few minutes, my laptop will crash and re-boot. do you think my old hard disk is dead beyond repair? or you can offer some help here? any assistance would be appreciated!

  • Netgear Router missing Wireless Configuration Menu Link

    - by ccisystems
    I have a Netgear WiFi router DG834G v3. On it it says it's a WiFi, ADSL 2+ modem, switch, etc. There is an antenna on the back and a WiFi indicator on the front. However, when I connect to it via the web interface, the wireless setup link is missing from the menu. The top label indicates it is a DG834 (without G). I have received it from a friend and was really looking forward to using it but I really need the WiFi part. I looked on Netgear's site as I thought someone must have uploaded the wrong firmware for the device sometime - so I upgraded to the latest firmware, but it still says it's NOT a 'G' device and the wireless menu is nowhere to be found. I'd appreciate a push in the right direction as to what I could do. Is it possible that the WiFi chip is broken or something and the device does not detect it and the firmware reverts the device to a different version?

  • How can you achieve and maintain flow while pair programming?

    - by bizso09
    Flow is a concept introduced by Mihaly Csikszentmihalyi; in short, it means to get into the "zone". You feel immersed in your task, focused; the task can be difficult but challenging at the same time. When people achieve flow their productivity shoots up. Programming requires a great deal of mental focus because we often need to juggle several things in our minds at once. Many like to work in a quiet environment where they can direct their full attention to the task. If they are interrupted, it may take several minutes or even hours to get back into flow. I understand there's a practice in agile development and extreme programming called pair programming. It means you put the whole software development team in one room so that communication is seamless. You do write code with your pair because this way you get instant code reviews and fewer bugs get through. I've always had problems achieving flow while doing pair programming because of constant interruptions. I'm thinking deep about an issue then all of sudden someone asks me a question from another pair. My train of thought is lost. How can you achieve and maintain flow while pair programming?

  • Subversion for web designer: repository on a network share and ftp to the live server?

    - by ceatus
    My configuration: htdocs on a windows network share (z:) web developers check out with dreamweaver modify and check in back to the drive z LAMP running on a Ubuntu server virtualized on Hyper-V with apache that point on the z drive for dev in order to test the websites Upload by FTP on the live server Now: I need multiple access to the repository, keep them on a network shares and we manage about 200 websites. All the web developers, administrators and IT need to access to the share. I found out that creating a svn server is the best way for me, so I created it on a Ubuntu Server which is virtualized on Hyper-V. Right now I have the repos local on the Ubuntu Server but I'd like them on my network drive and I'd like to have a post-commit, if possible, in order to ftp directly on my live server. Do you guys think that a WebDav solution would be better? Thanks in advance Angelo

  • Dual boot on Hp Envy Ultrabook

    - by phodu_insaan
    I just bought a HP Envy ultrabook 1002TX. It comes with a Win7 Home basic and a 32GB SSD + 500GB HDD. I started to install ubuntu and in doing so went and deleted all the partitions on my HDD and recreated them the way I wanted. Then when I tried to install ubuntu it didn't recognize my HDD. To solve this i typed dmraid -E -r /dev/sdX where the 'X' was my SSD drive. After this ubuntu can install but windows for some reason does not install. Also the Intel Caching feature is lost and SSD is just sitting and doing nothing. I want to know how to solve this problem. Ideeally I would like to use the SSD for caching, either in windows or ubuntu. How do I get the SSD back to working as an Intel rapid cache? How do I get windows to install properly? It tell me that windows is unable to configure itself to my hardware, and my PC came with windows pre-installed so this is not possible. Sorry for the long question and thanks for your answers! PS: At one time when I booted I pressed Ctrl+i and went to the intel rapid cache menu. I think i screwed up something in here, because only after this the rapid cache stopped working, and each time I booted the PC thought the BIOS was my primary disk.

  • Using international phone numbers on iPhone [closed]

    - by Cawas
    Spin off question Is it possible to hack a SIM card to add a javacard application on it (to properly format international numbers)? If yes, how? Original Question In my previous phone carrier I could just dial +55 11 99883655 and it would just work. Now I moved to a new carrier and it doesn't work anymore! When I dial the same international number it keeps saying the number isn't formated correctly. How can I get my iPhone to understand international numbering back again? I've got over 100 contacts with numbers stored in this format already, and I want to keep them that way. edit: I originally asked this question here, moved it to apple stackexchange and now I'm bringing a new one (hopefuly).

  • Chrome and Firefox freeze when I begin typing

    - by mschulze
    Last night, chrome began freezing whenever I tried to type anything. After a fresh reinstall the problem went away but it is back again this morning. I installed Firefox as a substitute browser but it has the same problem. I cannot even get past the homepage because typing in the u r l bar freezes both programs. Last night internet explorer froze once too, but it has not happened since. Disabling shock-wave does not have any affect on the problem. Because it is happening across multiple browsers, I do not believe it to be caused by any extensions I have installed on Chrome. I also tried running Chrome as a new user and the problem still occurred. I can open any apps or web sites that are on my homepage, but as soon as I try to type anything the program freezes. Any ideas?

  • Why doesn't it seem to be any development in the field of 3D VR gear, especially with regard to gaming?

    - by neuviemeporte
    I remember that way back around 1995, there was this big craze with VR in the media, a whole bunch of (mostly mediocre) games labeled as "virtual-reality-interactive-movie (...)" were published. If I recall correctly, the first 3D VR helmet was called VFX-1 and was sold bundled with Descent and some dedicated joystick. I never owned one, and I read just one review which was mostly enthusiastic, but pointed to some weak points, like the eyes getting tired after an hour or so of playing. Then the whole thing basically flickered down and died. I suppose the main reason it wasn't successful was that the hardware of the day was not powerful enough, the VR gear's design wasn't perfected to make it comfortable and natural to use, and the companies that made it failed to market it successfully. What I can't understand is why isn't there any development in the field today. There is some vr-ish hardware mostly targeted at the consoles (Kinect, Wii remote, TrackIR), but all projects of creating some 3d head-mounted display system seem to be in early infancy, appear once in a trade show somewhere and aren't heard of again. I think it could work great with head tracking and some of today's shooters, flight sims (trackIR is nice but the movement scale translation is awkward) and other games with an FPP POV. Is there any technological reason why decent vr headgear can't be made today, or is it just that nobody really cares/everyone is scared to repeat the '90s failure?

  • How do I increase the open files limit for a non-root user?

    - by iCode
    This is happening on Ubuntu Release 12.04 (precise) 64-bit Kernel Linux 3.2.0-25-virtual I'm trying to increase the number of open files allowed for a user. This is for an my ecplise java application where the current limit of 1024 is not enough. According to the posts I've found so far, I should be able to put lines into /etc/security/limits.conf like this; soft nofile 4096 hard nofile 4096 to increase the number of open files allowed for all users. But, that's not working for me, and I think the problem is not related to that file. For all users, the default limit is 1024, regardless of what is in /etc/security/limits.conf (I have been rebooting after changing that file) $ ulimit -n 1024 Now, despite the entries in /etc/security/limits.conf I can't increase that; $ ulimit -n 2048 -bash: ulimit: open files: cannot modify limit: Operation not permitted The weird part is that I can change the limit downwards, but can't change it upwards - even to go back to a number which is below the original limit; $ ulimit -n 800 $ ulimit -n 800 $ ulimit -n 900 -bash: ulimit: open files: cannot modify limit: Operation not permitted As root, I can change that limit to whatever I want, up or down. It doesn't even seem to care about the supposedly system-wide limit in /proc/sys/fs/file-max # cat /proc/sys/fs/file-max 188897 # ulimit -n 188898 # ulimit -n 188898 So far, I haven't found any way to increase the open files limit for a non-root user, and I really don't want to be running my application as root. How should I properly do this? I have looked at all the posted and tried the given options but no luck!

  • What You Said: How You Organize a Messy Music Collection

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your tips, tricks, and tools, for managing a messy music collection. Now we’re back to share so great reader tips; read on to find ways to tame your mountain of music. Several readers were, despite having tried various techniques over the years, fans of doing things largely the manual way. Aurora900 explains: I spent a weekend sorting everything myself once. Took a while, but now I have folders sorted by artist, and within the artist folders are folders for their albums. With my collection at about 260gb, it can be a daunting task, but it’s well worth it in the end. I don’t have the tagging issue as I make sure anything I have is properly tagged to begin with… If I’m ripping a CD I use Easy CD-DA Extractor, which automatically searches a database on the internet for the tags. If I’m downloading something, if its from a reputable source its going to be properly tagged already.

  • How to configure Logitech Marble trackball

    - by user27189
    You can configure it using xinput. I tested this in 11.10 and it works very nicely. This selection is from "Ubuntuwiki" Avoid using Hal for this release because it has known issues. Put the following into terminal, using gedit: Edit $HOME/bin/trackball.sh using this command: gedit $HOME/bin/trackball.sh Then paste this into the file: #!/bin/bash dev="Logitech USB Trackball" we="Evdev Wheel Emulation" xinput set-int-prop "$dev" "$we Button" 8 8 xinput set-int-prop "$dev" "$we" 8 1 # xinput set-int-prop "$dev" "$we" 8 1 # xinput set-int-prop "$dev" "$we Button" 8 9 # xinput set-int-prop "$dev" "$we X Axis" 8 6 7 # xinput set-int-prop "$dev" "$we Y Axis" 8 4 5 # xinput set-int-prop "$dev" "Drag Lock Buttons" 8 8 Make sure trackball.sh begins with #!/bin/bash. Make the script executable by running this: chmod +x $HOME/bin/trackball.sh` Add the following lines to $HOME/.bashrc, using gedit $HOME/.bashrc and put this in the file even if it is empty: xmodmap $HOME/.Xmodmap > /dev/null 2>&1 $HOME/bin/trackball.sh Edit $HOME/.Xmodmap using: gedit $HOME/.Xmodmap pointer = 1 8 3 4 5 6 7 9 Log out and back in and viola!

  • Putting DSMD into Remission

    - by Justin Greenwood
    As a programmer with over ten years of professional experience, I've often suffered from DSMD (distraction surplus/motivation deficit) disorder. I know I'm not alone. Many of my colleagues have shared their experiences with this productivity cancer to me in support groups or in moments of inebriated intimacy. Often, I observe friends unknowingly surrendering to it - sitting at their computer, cycling through the same set of web sites (blogs, facebook, youtube, news providers, wikipeida, etc.), over and over again. Intermittently, they get up, take a walk around the office, make small talk with their colleagues, get another cup of coffee, then sit down and start the cycle all over again. It is completely controlled by the subconscious mind and will destroy your ability to get into that groove you used to live in back in your better days. Programming requires extended periods of focused attention, and this type of behavior will really kill productivity and in the end, when deadlines are near, launch your stress level to near emotional breakdown levels.DiagnosisThe best way to diagnose infection is to completely disconnect your devices from the internet while working. If you find yourself launching web browsers every minute or so, then you're down with the sickness.TreatmentA few techniques I've found that will help send this ailment into regression are as follows:Segment your day into two to three hour work segments. For example: 9:00-11:00, 1:00-3:00, 3:30-5:00.Define a few small one to two hour tasks you want to accomplish in your day. Assign each of those tasks to one of the short work segments.If possible, turn off the internet and any other distractions during these work segments (at least until you regain control of your browsing habits) - this includes instant messaging and email. You can check your email and waste time surfing in the hours between work segments.Reward yourself on productive days with a beer or whatever butters your muffins.

  • SEAGATE Barracuda 7200.11 HDD not running

    - by Dane411
    After a huge research, I'm stuck at the beggining of getting my HDD data back. Whats happening to me is that in the moment when I plug the power wire to my external 1TB SEAGATE Barracuda 7200.11 ST31000333AS HDD Fw LC15, it makes the sound like it's spinning to almost full speed and then shuts down and spins up again, and so on. It's well known that those HDDs have a bad firmware that someday randomly fails. There are like 2 main problems identified, BSY (busy) state, and LBA0 error. Last time I connected it to power nothing happened, it didnt try to start at all, is it that so called bricked state? I guess my HDDs error is the first one, but I dont really know if what I described is that BSY state or not, neither I know how to check it. How could I know it? Thank you so much!

  • Learning good OOP design & unlearning some bad habits

    - by Nick
    I have been mostly a C programmer so far in my career with knowledge of C++. I rely on C++ mostly for the convenience STL provides and I hardly ever focus on good design practices. As I have started to look for a new job position, this bad habit of mine has come back to haunt me. During the interviews, I have been asked to design a problem (like chess, or some other scenario) using OOP and I doing really badly at that (I came to know this through feedback from one interview). I tried to google stuff and came up with so many opinions and related books that I don't know where to begin. I need a good through introduction to OOP design with which I can learn practical design, not just theory. Can you point me to any book which meets my requirements ? I prefer C++, but any other language is fine as long as I can pick-up good practices. Also, I know that books can only go so far. I would also appreciate any good practice project ideas that helped you learn and improve your OOP concepts. Thanks.
