  • iPhone Lag Terrible - SLOW - What's going on with the iPhone OS?

    - by Sam Schutte
    I've had my iPhone 3G for about a year now, and it seems like at least once a month, it gets bogged down and gets slower and slower - horrible lag when typing, going back to the home screen or opening an app can take 20 seconds. Has anyone else run into this and found "the" solution. What you always read on other boards is to reboot the handset (hold down home and the power button), but that doesn't improve anything for me. I've reinstalled the OS like 5 times now, and I'm getting pretty sick of doing it so often. And I don't buy that it's a hardware issue really, since it works fine for weeks after a fresh install. Anyone have a solution or an idea of what specific actions cause this kind of evident data corruption (OS corruption?) and slowness? Note - I'm looking for specific things here. That is, has anyone done the research to see exactly what on the phone operating system is getting messed up that causes this lag (which is discussed all over the internet, with no working solutions). I don't own a mac, so I can't delve into the guts of the iPhone very well to see what's up with it... Some additional info: Reboots (hold down power/home) and "Sleeps" (slide off) do nothing. Only fresh re-installs help I only have about 15 apps installed - sometimes you see the answer to uninstall apps if you have too many, I'd hope that 15 isn't too many, and even when I've had none installed, it still gets hung up after a period of time. This phone is not jailbroken, and it is running the 3.0.1 release.

  • Is Grub installed when Ubuntu is the only OS installed?

    - by Dennis
    I have a simple question concerning Grub. When Ubuntu it's the only system installed on a machine, Grub doesn't appear when the computer it's turned on, my question is: When Ubuntu is the only system, Grub it's not installed on MBR? I has this doubt when I tried the ASPM command in Grub, to see if it could save some battery on my notebook, and the difference was only 0.4W. I don't even know if it made some effect or it's just a normal oscilation. Thanks.

  • What is the best idea to put available OS (linux) and Web application to client?

    - by Fernando Costa
    After a year programming a web based business management system, I got my idea divided into two differents ways to do what I'm doing... I will try to explain in follow lines: First I will describe my enviroment: Webserver: apache, ngynx Programming Language: PHP, Shell Script, Java Script, SQL Database: Mysql Operating System: Linux, UNIX (All Distros) (If manually configured works on windows) Authentication Server: FreeRadius First situation I have my application running on this enviroment that I had just described before, as my application is a SaaS app, then I have my own server to run it all and customers pay to use it as a service accessed by webbrowser. Second Situation The same as before but with one big difference, everything (environment) is installed in the customer, then I need to cryptography all my codes (It includes PHP and Shell Scripts). I think this situation is most difficulty, but I would like to hear it from different points of view.

  • In the context of semantic versioning, does a change in the default configuration warrant a new major version?

    - by michielvoo
    My module is enabled by default (i.e. when you add the module). There's also a configuration you can optionally use, which supports an enabled="true|false" setting. This way the module can be disabled after it's been added, without the need to remove the module. But I realized the module doesn't play nicely with another module that is also enabled by default. I am considering changing my module so it's not be enabled by default. This would break for anyone that has not explicitly enabled it with the enabled="true" configuration setting. Should I wait for v2.0 for this? semver.org mentions the public API and breaking changes, not configuration. Is it generally accepted that configuration is part of the public API?

  • Why do fonts sometimes look "fat" on Mac OS X?

    - by jtimberman
    Sometimes when resuming from suspend, the fonts in Mac OS X look "fatter" than normal. Unfortunately right now I can't get my Macbook Pro to exhibit the "normal" behavior for comparison, it has been abnormal yesterday and today. If I can get screenshots of what I think is 'normal', I'll add them. "Fixing" this has been random. I use an external monitor, and sometimes unplugging it and plugging back in, or even turning it off and back on has worked. Sometimes with the display attached (or not) detecting displays works. Sometimes logging out or rebooting entirely is what it takes. Displays used: Macbook Pro 15" built-in display Dell 27" LCD (2009 model) Software where I see this happen, at least most noticably: Firefox (screenshots below) iTerm Things MacIrssi (screenshots below) I am using Mac OS X 10.5.8. "Abnormal" view from MacIrssi with Inconsolata 16 pt. image full size "Abnormal" view from Firefox. Finally got it to switch back, though after resuming from suspend its back to "fat" :-(. image full size And 'normal' in Firefox:

  • How can I get a DisplayLink USB monitor under Ubuntu (any recent version) ?

    - by jfmessier
    I have a DisplayLink-based external USB monitor, which has both power and data over USB, and seems to work perfectly under Windows 7, but only can display a text console under Ubuntu 10.10, and that I can only use when I am actually switched to it. So the only Use I can have so far is to have some text-based monitoring or console that I can watch while working on the graphic display. I know there are some development done for DisplayLink, but I never could get it to actually run properly. Yes, I tried the detailed setup described in other posts, but they did not work, and instead crashed my X that I had to restore. Merci :-)

  • OS X borked; need to backup outside of Time Machine

    - by rlbgator
    Quick Background: iMac G5 (the white one; 4 years old?) Running Leopard 10.5.something. Time Machine started failing on me; and every time I touch the Finder, things beachball like crazy. Booting from install disk then using Disk Utility to "Repair Disk" also fails. I'm left with the conclusion that I have a corrupt file somewhere important, that's (i) keeping TM from working and (ii) messing with basic functionality. I am not (yet) savvy enough in OS X to know what logs to look in, or how to decipher them - but 'corrupt file' seems to be the likely case, based on my readings of apple.com forum threads. So I think I need to backup, outside of Time Machine, then install fresh OS X on a new drive (or maybe SpinRite the current drive?). I'm able to put a (non-Time Machine) external USB drive on, so I dragged all 3 Users' folders to that... am I done backing up? Am I going to have a massive Permissions problem, trying to put things back together after a re-install? Thanks for reading.

  • Update a bootable OS X drive clone with rsync?

    - by Joe
    The question: is it possible to keep a boot-able backup drive clone of OS X updated with rsync? If rsync is not a viable option are there alternatives? The Setup: My situation is as shown above. One internal Samsung 840 SSD [120g] in use as my OS X 10.8 boot disk on a recent model Mac Mini. I have successfully cloned that drive with disk utility to a 125g partition of another HDD in an external USB 3 enclosure and at that point I am able to boot to it. The Goal: As my last system went out in a fiery blaze taking much valuable data with it, I have a new respect for a proper backup solution and really want to do this right. My goal is to achieve an automated differential backup/update from Disk A to Disk B while most importantly maintaining boot-ability on the external drive. And I would prefer to do this differentially to minimize stress on the drives. Hence rsync was the first thing to come to mind. What I have tried: following along with Jamie Zawinski's differential mac bootable backup solution running this manually initially worked - i tested it with only very miniscule file change and everything was fine / external booted and all. now after subsequent passes rsync fails throwing errors particularly relating to updating 'boot.efi' (not at the machine currently I will update the precise log message once I return home) is this a drive partition size issue? does rsync require more space? if it cant be done, are there any alternatives? i've heard whispers of dd

  • OS X superuser folders automatically created. Perusers launchd process appears to kill 501

    - by Ric Pen
    New Apple laptop OSX 10.8.2. I have used OS X but many years previously, and am not familiar with subtleties or changes in com.apple.launchd.peruser.x... I have previously (and in retrospect, foolishly) made changes to these rapidly spawned new peruser accounts (my initial reaction was that if ipfw was disabled, then I might well be under hacker attack, which I have dealt with, years ago), but I believe I was wrong, and the results of my efforts at preserving the system's integrity have in fact been destructive, overreactive, and have resulted in much work to restore. My understanding from other posts is that superuser protocols have changed quite dramatically since I bought the first developer version of OS X many years ago. Haven't developed on Apple much since then, w/ exception of WebObjects (IMO, much underrated at that time, and was more user friendly than ASP (prior to .NET, I vaguely recall). Creation of apparently nasty peruser folders appear to confound 501 process, which logs inability to find firewall (ipfw). Can someone help me with this? I am concerned that either the system is improperly configured, an application was improperly installed (although there is little here beyond Apple's SDK, which I find quite accommodating and intuitive). Still, I am a novice, only sporadically develop at this time, and would really just like to see this system running happily. Please offer assistance, in the form of potential info sources, or if you have had a similar experience, then perhaps scripts to suss out this issue. I do not wish to damage the system, but Apple's Developer connection and discussion threads do not appear to have dealt with this particular issue recently... Although I may well have missed something you have not - please apprise. Any assistance on this issue is very much appreciated - by an old guy, who wants to do some things which were fun about 20 years ago.

  • Digg Reader déjà disponible en version bêta, Facebook proposera-t-il aussi finalement une alternative à Google Reader ?

  • How can I get started programming OpenGL on Mac OS X?

    - by Michael Stum
    I'm trying to start OpenGL programming on a Mac, which brings me into unknown territory on a lot of things. During the day, I'm a Web Developer, working in C# and before that in PHP and Delphi, all on Windows. During the night, I try to pick up Mac/OpenGL skills, but everything is so different. I've been trying to look for some books, but the OpenGL books are usually for iOS (tons of them out there) and the Mac Books usually cover "normal" application Development. I want to start simple with Pong, Tetris and Wolfenstein. I see that there are a bunch of different OpenGL Versions out there. I know about OpenGL ES 1&2, but I don't know about the "big" OpenGL Versions - which ones are commonly supported on 10.6 and 10.7 on current (2010/2011) Macs? Are there any up to date (XCode 4) books or tutorials? I don't want to use a premade Engine like Unity yet - again, I know next to nothing about any Mac development.

  • Memory limiting solutions for greedy applications that can crash OS?

    - by Hooked
    I use my computer for scientific programming. It has a healthy 8GB of RAM and 12GB of swap space. Often, as my problems have gotten larger, I exceed all of the available RAM. Rather than crashing (which would be preferred), it seems Ubuntu starts loading everything into swap, including Unity and any open terminals. If I don't catch a run-away program in time, there is nothing I can do but wait - it takes 4-5 minutes to switch to a command prompt eg. Ctrl-Alt-F2 where I can kill the offending process. Since my own stupidity is out of scope of this forum, how can I prevent Ubuntu from crashing via thrashing when I use up all of the available memory from a single offending program? At-home experiment*! Open a terminal, launch python and if you have numpy installed try this: >>> import numpy >>> [numpy.zeros((10**4, 10**4)) for _ in xrange(50)] * Warning: may have adverse effects, monitor the process via iotop or top to kill it in time. If not, I'll see you after your reboot.

  • Firefox va supporter le H.264 dans sa version mobile après avoir bataillé contre ce codec propriétaire : pragmatisme ou renoncement ?

    Firefox supporte le H.264 après avoir longtemps bataillé contre ce codec propriétaire : pragmatisme ou renoncement ? Le codec H.264 a longtemps fait débat divisant les navigateurs en deux clans. Mozilla s'était rangé dans le camp contre ce codec, refusant catégoriquement d'obtenir une licence propriétaire pour son Firefox. La fondation militait depuis le début pour un web ouvert à 100%. Mais voila que sur le groupe de discussions de ses développeurs, Andreas Gal, Directeur de la recherche de Mozilla, annonce un virage. Du moins en ce qui concerne la future plateforme mobile de la fondation à but non lucratif. [IMG]http://ftp-developpez.com/sarah-mendes/logo_...

  • Tell me why I should bother using Linux if it's all about problems getting the OS to install or work properly? [closed]

    - by Vilhjalmur Magnussin
    Why should I spend day's trying to get Ubuntu to either install and/or work properly? I'm using an Acer Timeline X laptop and if I install 10.04 the wireless doesn't work, and if I try installing 11.04 it either won't install, or if it installs it's full of bugs causing my computer to freeze all the time. So please, I'm all open ears. Someone give me one or two good reasons to continue wasting time (in hope it eventually works) before I decide to focus my time on other things like productivity (using Windows like I've been doing successfully the last 10 years). This is the second time I give Ubuntu a try, the first time was in 2010 using Ubuntu Studio and Ubuntu Desktop, and it ended with me shifting back to Windows since I had spent more time getting everything to work than actually working while trying Ubuntu. I really don't understand why it needs to be like this. Why go on trying when all I see is forums full of discussions about problems which people are having difficulties fixing. Or maybe there is just one special type of computer which works well with Linux? Would very much like to know which computer that is. SO please, if it's not to much trouble I really want to here from someone who has something good to say about going through all this trouble just to get a working environment up and running since I already have a working environment up and running called Windows. Thanks, Villi.

  • Can I require a large donation ($499) in order for a company to receive an extended version of my open source project? [closed]

    - by Damian
    I want to make my project open source but some of its more advanced features are targeted to companies so I would like to require a donation before I send the source code to the donating company. It will be something like that: "If you want to use the extended features of XXXXXXX, please make a donation of $499 and you will receive the source code and the jar with the extended features. You will also receive personalized support by email." Is it legal and acceptable to do something like that? Can the companies donate an amount like that to an open source project? I mean, is it easy for them in terms of their accounting, tax, etc. to donate $499 dollars to an open source project. I know it is not a matter whether they will have money or not but more of a paying procedure matter.

  • Is version history really sacred or is it better to rebase?

    - by dukeofgaming
    I've always agreed with Mercurial's mantra, however, now that Mercurial comes bundled with the rebase extension and it is a popular practice in git, I'm wondering if it could really be regarded as a "bad practice", or at least bad enough to avoid using. In any case, I'm aware of rebasing being dangerous after pushing. OTOH, I see the point of trying to package 5 commits in a single one to make it look niftier (specially at in a production branch), however, personally I think would be better to be able to see partial commits to a feature where some experimentation is done, even if it is not as nifty, but seeing something like "Tried to do it way X but it is not as optimal as Y after all, doing it Z taking Y as base" would IMHO have good value to those studying the codebase and follow the developers train of thought. My very opinionated (as in dumb, visceral, biased) point of view is that programmers like rebase to hide mistakes... and I don't think this is good for the project at all. So my question is: have you really found valuable to have such "organic commits" (i.e. untampered history) in practice?, or conversely, do you prefer to run into nifty well-packed commits and disregard the programmers' experimentation process?; whichever one you chose, why does that work for you? (having other team members to keep history, or alternatively, rebasing it).

  • International multi-OS keyboard layout for both coding and surfing?

    - by Nikolai Prokoschenko
    So yes, the problem has been raised in parts multiple times already. Still I'm looking for a keyboard layout that has the following features: Easy on fingers (Dvorak-like layouts welcome) Easy for coding Includes German characters (typing ä with AltGr-p is not ok). Works well with web-browsing (Ctrl-t and Ctrl-w on one hand, left one very much preferred, since that's where my ex-CapsLock, now Ctrl lies) Works well with default Emacs bindings Works on both Windows and Linux (at least easily installable) I've looked at Dvorak and Neo, they both have a "shortcut problem", i.e. web-browsing and most frequent Emacs combinations use both parts of the keyboard. Using right Ctrl is usually not an option, since it'll give me RSI much faster than keeping QWERTY/Z. Funnily enough, mirroring the default Neo layout would probably be enough for me. So, any ideas?

  • How far back do you use your version control and for what reason?

    - by acidzombie24
    Typically when i work on a project i only go back a few days or the last major change when i decide to do something drastic. I sometimes notice i broke a test or a feature and overlooked it for a few weeks so i may go back a month or two and see if the feature or test is broken and trace down the week i broke it. Then find what change did it. On a long term project over the span of a year. Do you actually go back 6+ months and if so why?

  • I receive the error 'grub-install /dev/sda failed' while attempting to install Ubuntu as the computer's only OS.

    - by Liath
    I am attempting to install Ubuntu on a box which was previously running Windows 7. I have also experienced the dreaded "Unable to install GRUB" error. I am not attempting to dual boot. I have previously run a Windows boot disk and removed all existing partitions. If I run the Ubuntu 12.04 install CD and click install after the config screens, I get the error Executing 'grub-install /dev/sda' failed. This is a fatal error. (It is the same error as this question: Unable to install GRUB) All the questions I've read while looking for a solution are related to dual boot. I'm not interested in dual boot, I'm after a clean out the box Ubuntu install. How can I achieve this? (For my sanity, please use very simple instructions when responding. I don't claim to have any talent either for linux or as a sysadmin) Additional details copied from comments dated: 2012-05-29 ~15:19Z After booting from the CD, clicking Try Ubuntu, and then sudo fdisk /dev/sda I get fdisk: unable to seek on /dev/sda: Invalid argument sudo fdisk /dev/sdb gives Device contains neither a valid DOS partiion table, nor Sun, SGI or OSF disklabel.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite). Command (m for help): I should add the Live CD desktop is graphically bad. I've got missing parts of programs and the terminal occasionally reflects to the bottom of the screen. But I can't imagine this is related.
