• Windows Error After Wubi Install

  - by user106563

  The initial install on my laptop was Windows 7. I installed Wubi on Sunday - the install seemed fine. I was able to log in and use both Ubuntu and Windows. On Monday I started receiving the following error in Windows: windows cannot access the specified device path or file This occurs on every link I click on - essentially rendering Windows unusable. I do not experience the same problem when Windows is started up in safe mode. I have tried numerous virus scans (Malware bytes, Avg, AdAware) and have removed various trojans etc. Windows is still unusable. Ubuntu seems fine so far. My question is, can this error be attributed to the Wubi install?

• How to document and teach others "optimized beyond recognition" computationally intensive code?

  - by rwong

  Occasionally there is the 1% of code that is computationally intensive enough that needs the heaviest kind of low-level optimization. Examples are video processing, image processing, and all kinds of signal processing, in general. The goals are to document, and to teach the optimization techniques, so that the code does not become unmaintainable and prone to removal by newer developers. (*) (*) Notwithstanding the possibility that the particular optimization is completely useless in some unforeseeable future CPUs, such that the code will be deleted anyway. Considering that software offerings (commercial or open-source) retain their competitive advantage by having the fastest code and making use of the newest CPU architecture, software writers often need to tweak their code to make it run faster while getting the same output for a certain task, whlist tolerating a small amount of rounding errors. Typically, a software writer can keep many versions of a function as a documentation of each optimization / algorithm rewrite that takes place. How does one make these versions available for others to study their optimization techniques?

• How do you go about checking your open source libraries for keystroke loggers?

  - by asd

  A random person on the internet told me that a technology was secure(1), safe to use and didn't contain keyloggers because it is open source. While I can trivially detect the key stroke logger in this open source application, what can developers(2) do to protect themselves against rouge committers to open source projects? Doing a back of the envelope threat analysis, if I were a rogue developer, I'd fork a branch on git and promote it's download since it would have twitter support (and a secret key stroke logger). If it was an SVN repo, I'd create just create a new project. Even better would be to put the malicious code in the automatic update routines. (1) I won't mention which because I can only deal with one kind of zealot at a time. (2) Ordinary users are at the mercy of their virus and malware detection software-- it's absurd to expect grandma to read the source of code of their open source word processor's source code to find the keystroke logger.

• Most effective marketing strategy to promote a casual iOS game?

  - by user1114968

  So I posted this on another forum yesterday but that forum got suspended for malware so gotta wait for the webmaster to fix the site. Here's the basics: We've released a press release through PRMac that included a video review. Submitted and followed up on all the big iOS review sites. None of them replied back with interest. A lot of them just told me that their editors are volunteers who will review games that are "interesting to their readers" and that they would put my app "into consideration" The only site that reviewed our app and promoted virally was iPhoneAppReview.com which we paid. We promoted on the top iOS forums We are now doing in-app advertising through inMobi and are integrating the SDK code into our app to start doing Tapjoy We posted up our gameplay videos on YouTube Any marketing strategies that anyone can suggest or recommend that we haven't used yet? If anyone wants to try out our game and give feedback on the game or the site or anything, that would be great! Our target countries are Japan, China, and the US.

• failure to upgrade to 13.10 on ASUS 1015E-DS03

• How can IIS 7.5 have the error pages for a site reset to the default configuration?

  - by Sn3akyP3t3

  A mishap occurred with web.config to accommodate a subsite existing. I made use of “<location path="." inheritInChildApplications="false">”. Essentially it was a workaround put in place for nested web.config files which was causing a conflict. The result was that error pages were not being handled properly. Error 500 was being passed to the client for every type of error encountered. Removal of the offending inheritInChildApplications tag from the root web.config restored normal operations of most of the error handling, but for some reason error 503 is a correct response header, but the IIS server is performing the custom actions for error 403.4 which is a redirect to https. I'm looking to restore defaults for error pages so that the behavior once again is restored. I then can re-add customizations for the error pages.

• how can I contact Google about a domain misuse?

  - by questy

  I was trying to add a newer domain of mine to my existing Google Apps account with an already set primary domain. Google Apps then returns the message that the domain is already in use by another account. I tried finding a way to contact Google, but they have a wall up preventing anyone with an original Apps account from calling them. There's a help page saying to try retrieving the password, but how is that even possible? I don't know the email address of the owner of the Apps account using my domain, and I don't know his/her name on the account, so I can't complete the form for retrieving any of the information. Google Productforums is always a dead end. Does anyone here know how to force a removal of a domain on Google Apps from someone that doesn't own it?

• How can I remove bluetooth-applet in 11.10?

  - by dunderhead

  I tried adding rfkill block bluetooth to /etc/rc.local. This did not work. I tried adding both blacklist bluetooth and blacklist btusb to etc/modprobe.d/blacklist.conf. This did not work. So I went to Synaptic to remove it altogether, but when I marked bluez for removal it said it was going to also remove gnome-shell as well! So naturally I didn't do that. (Is it sane to run a potential security problem like bluetooth by default? And why is something like that so tightly integrated into Gnome shell?) Can anyone tell me how to get rid of this annoying and unnecessary process?

• Please help me to improve Re-Sharper

  - by TATWORTH

  Re-Sharper is an excellent aid to producing good code in either C# or VB.NET. Recently through using Resharper and StyleCop, I have found three area where ReSharper needs to be improved. Please log into the YouTrack at http://youtrack.jetbrains.net and vote for the following: RSRP-268868 Improvement to removal of redundant else and invert if optimisations for enhanced stylecop compliance. When Resharper removes a redundant else, there needs to be a blank line added. Currently there is no provision to specify this. Please vote for this! RSRP-272286 Resharper Feature Request to move initialisation to static constructor Currently ReSharper offers moving initialisation of of non-static variable to a constructor. Why not offer the same for a static constructor?  Please vote for this! RSRP-272285 Expansion of Switch Statement by Resharper Currently ReSharper will fill an empty switch statement based upon an enumeration but will not add missing enumeration values to such a switch statement.   Can't code withoutCoding assistance, smart code editing and code completion for C# and VB.NET

• How to tackle archived who-is personal data with opt-out?

  - by defaye

  As far as I understand it, it is possible to opt-out (in the UK at least) of having your address details displayed on who-is information of a domain for non-trading individuals. What I want to know is, after opt-out, how do individuals combat archived data? Is there any enforcement of this? How many who-is websites are there which archive data and what rights do we have to force them to remove that data without paying absurd fees? In the case of capitulating to these scoundrels, what point is it in paying for the removal of archived data if that data can presumably resurface on another who-is repository? In other words, what strategy is one supposed to take, besides being wiser after the fact?

• How do I best remove an entity from my game loop when it is dead?

  - by Iain

  Ok so I have a big list of all my entities which I loop through and update. In AS3 I can store this as an Array (dynamic length, untyped), a Vector (typed) or a linked list (not native). At the moment I'm using Array but I plan to change to Vector or linked list if it is faster. Anyway, my question, when an Entity is destroyed, how should I remove it from the list? I could null its position, splice it out or just set a flag on it to say "skip over me, I'm dead." I'm pooling my entities, so an Entity that is dead is quite likely to be alive again at some point. For each type of collection what is my best strategy, and which combination of collection type and removal method will work best?

• MinGw Multiple Definitions

  - by makuto

  I'm trying to get the MinGw C++ compiler set up so I can compile my code for Windows computers and I'm having troubles. I originally installed minGw32 but then found that mingw-w64 was a better fit for me, so I uninstalled minGw32 and installed mingw-w64. The problem is that when I try to compile a simple hello world application I get Multiple Definition errors (which are not from my code). I'm thinking it has something to do with the removal of w32 and the installation of w64 without a clean directory. How do/should I clean the necessary folders & get rid of those multiple definitions.

• Bad links point to old domain - should I disavow on new domain?

  - by user32573

  I am working with a site which we'll call www.newdomain.com, which was hit by Penguin this month despite no unusual practices. I found lots of really spammy links to their old site, www.olddomain.com, which 301s to the new domain. So I've gone through the process of identifying which links are really bad, made contact to ask for removal, and am at the stage of disavowing links. But wait! None of the bad links point to newdomain.com, and I worry that a disavow request via this domain in Webmaster Tools will damage something. Do the old band links affect the new site? If so, where do I disavow those old bad links? On Webmaster Tools for the new domain?

• Result of the "How long do you wait before Solaris 11 gets on your prod systems?"

  - by nospam(at)example.com (Joerg Moellenkamp)

  I just removed the poll at 10:52, so this is the final result: My conclusions out of it: While the removal of UltraSPARC I to VI+ support in Solaris 11 may hit some of the people voting in the categories "Wait?" to "6 month", most of the users keep Solaris 10 running on their existing system anyway or migrate that late that even the newest system have reached their end-of-service-live or are near of it, so a migration doesn't sound that feasible. So i assume Product Management was right with their decision to remove the support in order to make the feature i can't talk of possible, as i don't think that many of the early migrators are still using the system in question, as most systems have reached EOSL. Didn't thought that there would be people waiting three years and more ...

• Theme is broken in some places

  - by RidiculeSwarm

  I am using a computer that started out on 11.10. I have since updated it several times, and installed and used a great number of WMs (Unity, XFCE, Gnome, KDE, Cinnamon). I am not sure how, but somewhere along the way (probably when I upgraded to Ubuntu 13.04), some parts of my desktop theme were broken. I have tried switching themes and installing new themes, but that does not work. Neither did a removal of (and log out/login cycle) the ~/.config/dconf folder work. Specifically: on several menus, the central part of a button icon is a "grey square" that doesn't fit in with the theme (picture below). the window and desktop right click menus looks ugly. The same kind of grey field covers the items, and the square checkbox looks weird (just filled with a uniform blue). The separator is a thick line that looks out of place. It seems to be a similar problem to that of window buttons (picture below).

• Can you disavow a whole domain apart from the index page?

  - by Silver89

  Many years ago I may have bought a few sitewide links for some of my sites, these have now come back to haunt me and I need to sort them out. I've tried to contact the owners but they're too lazy to bother changing the sites so I figure it's time to disavow the links. But is there a way to disavow all of the sitewide links on the domain apart from on the index page and would this be a benefit to leave the index or would it still be seen as spammy? Something like ... # Contacted owner of shadyseo.com on 7/1/2012 to # ask for link removal but got no response domain:shadyseo.com !shadyseo.com/index.php

• ubuntu 12.04: Why my laptop is consuming more power than 11.10?

  - by sanz

  I had 11.10 X86 on my Asus laptop (sandybridge, Nvidia 520M). I had 8 hours' battery life with Bumblebee and Jupiter. Average battery discharge rate was around 10w. Later I changed, not upgraded, to 12.04.1 AMD64. I installed Jupiter. But there is no "restricted drivers" available so I guess Bumblebee will not work. So I removed nvidia drivers. Now I only get 4 hours' battery life. Average battery discharge rate is around 19w. The removal of nvidia driver did not make any difference. What's the cause? Nvidia video card not disabled or 64b version of Ubuntu?

• Windows 7 Safety Tips

  The introduction of Microsoft's Windows 7 operating system meant many new features for its users in the way of both functionality and security. With Windows 8 on the horizon, Microsoft customers can expect even more improvements, including integrated security features to help provide a solid barrier against malware and other malicious creations that have made their way into the tech landscape. The Windows 8 release is still not here, however, so many running Windows 7 will have to wait for such enhancements. That is no excuse for security lapses though, as there are many steps you can take...

• After upgrading to 12.04 lts server, the mouse is intermittently working

  - by Jason

  After this upgrade, I've had a problem with the mouse intermittently working and programs crashing (like zentyal crashing and the error reporting application crashing) I also had an error on the screen that said: "Could not grab your mouse. A malisious client may be eavesdropping on your session or you may have just clicked a menu or some application just decided to get focus. Try again." What's going on with this system? Did I really get malware that quickly? This system has been boxed up since 2011. I only did the upgrade today... In regards to the mouse I can move it around, but when I click on something, it doesn't work.
