• Hide 'Your profile could not be opened correctly'

  - by B. Roland

  Hello! I have a small public internet cafe, with Ubuntu 10.04 and 10.10. I'm using Google Chrome 7.0.517.44 (64615), with AutoScroll - Version: 2.7.5; AdBlock is removed because of high CPU loads, and unconfortable speed of machine. "Your profile could not be opened correctly" error is displayed: This image is only an illustration. The reason is that I changed permissions of some config files, to don't remember the history, there are no setting in options, to don't use history. I've been removed write permission to: ~/.config/google-chrome$ find . -group nopasswdlogin ./Default/Archived History ./Default/History ./Default/Visited Links When I solved all of my problem, I'll remove some other write permission, this is a public place. What methods are known to HIDE this message? Thanks!

• Gateway IP Returns to Zero

  - by Robert Smith

  When you set a static IP under Ubuntu 12.04.1, you must supply the desired machine IP and the gateway IP, all using the Network Manager. When I first entered them and rebooted, everything worked great. On the second boot, however, Firefox could find no Web page. Upon checking, I discovered that the gateway IP had returned to zero. Now, no matter how often I resupply it, it returns to zero immediately after NM "saves" it: that is, appears as zero when redisplayed. The only way I can get to the Internet is to restore DHCP operation. I need to use static IP for access to my home network. Would appreciate any suggestion. --Robert Smith

• Why is Python slower than Java but faster than PHP

  - by good_computer

  I have many times seen various benchmarks that show how a bunch of languages perform on a given task. Always these benchmarks reveal that Python is slower then Java and faster than PHP. And I wonder why is that the case. Java, Python, and PHP run inside a virtual machine All three languages convert their programs into their custom byte codes that run on top of OS -- so none is running natively Both Java and Python can be "complied" (.pyc for Python) but the __main__ module for Python is not compiled Python and PHP are dynamically typed and Java statically -- is this the reason Java is faster, and if so, please explain how that affects speed. And, even if the dynamic-vs-static argument is correct, this does not explain why PHP is slower than Python -- because both are dynamic languages. You can see some benchmarks here and here, and here

• How to stop Thunar being default file browser

  - by Charles Kane

  On a relatively new 11.04 installation Thunar has become the default file browser simply by using it! Whilst I can open Nautilus easily enough, I'd rather it remained as the default, especially when I choose to view files in dual pane. The only action that I can pinpoint that might have given over my files and folders to Thunar is making Nautilus into Nautilus-Elementary (oh and Unity carked it so I reverted rather unwillingly to Classic, glad I did it is so much more stable and this is my production machine and Unity acts as if it is early alpha as far as I can tell!)

• Formatting and installing Ubuntu over Windows 7 without admin password

  - by Emiliano Pasqualetti

  A borrowed a friend workstation with Windows 7 and Ubuntu 10.10. I do not have the administrator password and I would like to format everything and install Ubuntu 12.04. I have put the iso on the usb using PendriveLinux and restarted the machine. At the boot I am presented with several options but those Ubuntu ones simply load my friends Ubuntu 10.10 OS (for which I have no password). edit: I fixed this by pressing F12 at the boot before it gave me that prompt (called GRUB). I clicked USB and finally install.

• SharePoint 2010 Information Worker VM available for download

  - by Enrique Lima

  If you interested in a test drive of the technologies around the Wave 14 launch, take look at the VM made available from Microsoft. It is a very well rounded option to explore the new products. 2010 Information Worker Demonstration and Evaluation Virtual Machine Note:  It is important to understand you will need a system with Hyper-V to import this VM and get it off and working.  Also, make sure you keep a copy of the original unpacked VM as this is based on a trial version of the OS (time bombed) and there is a chance to rearm the VM, but you are better off either keeping the original files or taking a snapshot as soon as the VM is living in your Hyper-V environment.

• SPRoleAssignment Crazy Caviats

  - by MOSSLover

  I’m not sure if this bug exists on any other environment, but here are a few issues I ran into when trying to use SPRoleAssignment and SPGroup: When trying to use Web.Groups[“GroupName”] it basically told me the group did not exist, so I had to change the code to use Web.SiteGroups[“GroupName”]. I could not add the Role Assignment to the Web and run a Web.Update() without adding an additional Web.AllowUnsafeUpdates= true; , however on my virtual machine I could do a Web.Update() without the extra piece of code.  I kept receiving an error in my browser stating that I should hit the back button and update my permissions. So after fixing those two issues I was able to copy the permissions from a page item into a Site for my migration.  Hopefully, one of you can learn from my error messages if you have any issues in the future.

• Cannot boot from SD card/flash drive on Macbook Pro 13" - boot fails after purple screen

  - by user3512567

  It's my first time using Ubuntu and I have run into some problems. I have a 16GB USB Flash drive and 16GB SDHC Card. I would prefer to use the SD card but either will do just fine if it helps with the solution. I Have a 13" Macbook Pro with no hard drive deeming the machine useless without an OS. I thought I could substitute the hard drive for a 16GB SD card with an Ubuntu ISO on it. I would like to plug in my SD card into my Macbook Pro, boot the Ubuntu ISO and do simple things such as use the browser for internet. The Problem: Whenever I boot my Macbook pro with the SD card that has the Ubuntu ISO, it loads at the purple logo screen and does not function. How can I resolve this issue?

• Battling Emacs Pinky?

  - by haziz

  My problem is not so much emacs pinky as much as having to work with multiple machines, across 3 operating systems, both desktop and laptop, with differing keyboard layouts and different locations for Ctrl and Alt\Meta keys so I often have to pause and think about where is the Ctrl key on this machine. How do you deal with varying keyboard layouts, between Mac keyboards (mostly the laptops) and PC keyboards (mostly 101 keys in my case, yes the original PC keyboard)? I have turned the Caps lock Key into a Ctrl key (losing the Caps lock function completely rather than swapping with Ctrl) on most of them but still find myself hunting for the original Ctrl labeled key most of the time. How do you deal with this keyboard confusion? Suggestions, ideas and feedback welcome.

• Ubuntu won't boot, only displays GRUB terminal

  - by Badea Sorin

  I have a problem with my Ubuntu 11.04. I've installed Ubuntu 11.04 from Windows, it worked fine for days, but today it won't boot. When I start the machine, GRUB loads. There is the Windows 7 loader, I select Ubuntu from there and after that, I should see the Ubuntu GRUB menu, where I'd select the mode to boot Ubuntu. However, I can't see that anymore. I directly get to a GRUB terminal. Can anyone help me with this? How would I recover my data or reset the boot loader?

• Best hardware for a Ubuntu Computer?

  - by Dante Ashton

  Hey all. I'll be needing a new PC soon, but I've decided to build my own, so my question is...what's the best hardware for Ubuntu? Specifically, in terms of graphics cards; I'm looking for something that will run smoothly (for Compiz's effects and Unity) but will be quite modern (IE: have a HDMI output) The machine itself is just a generic computer, nothing special; I just want to future-proof it. I'm looking at quad-core chips and 3-4 gig of RAM. I want something that will play nice with Ubuntu; now, and in the future... I used to build machines years ago, but I've fallen behind (that was in the Windows 98 era...so yeah, quite a while ago!) My main problem is the graphics card; I'd prefer to stick with NVIDIA, but only a tiny amount of computers I've seen play nice with Nouveau.

• Change language encoding for file uploading

  - by jc.yin

  Previously we were running a Wordpress site on a Mac OS Server machine. We had several hundred images with Chinese characters for the image names. Now we're trying to migrate to a Ubuntu system and everything is fine except the images. Every time I try to upload an image with a Chinese name via FTP, I get the following message: "MyImage contains illegal characters. Please choose an appropriate text encoding" I have no idea how to solve this issue, do I need to somehow change the system language encoding in Ubuntu to allow for image uploading? Thanks

• It's 2011-Do You Know Where Your Children Are?

  - by andyleonard

  Introduction This is not a post about children. I was feeling plucky when I wrote this post at the end of last year. Sometimes when I feel plucky I'm inspired to create awesome blog post titles and ideas. Other times, this happens. 2011 Is Here! I was born in 1963. As I child I watched Neil Armstrong and Buzz Aldrin walk on the moon while Walter Cronkite narrated. At 11, I was fortunate enough to live next door to an engineer who taught me Motorola 6800 machine code and then BASIC . I have a long...(read more)

• Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error on localhost

  - by Ne0

  Background: I set up a cloud server and have have a website running SSL, it was all pretty strait forward following these instructions and following the instructions given by the SSL certificate issuer. I then went to set up development site on my local machine the same way but using self signed certs using these instructions. I have checked that port 443 is open and this post suggests it is a bad configuration on the server. I have gone through the set up process twice, yet I have been unable to find out what I have done wrong or missed. Does anyone else know what I may have have missed to get this error? Note: As the links suggest this is on 12.04.

• How do I open up firewall while keeping it safe?

  - by d3vid

  Since I've installed Firestarter I have encountered connectivity issues that are all resolved by disabling the firewall. I'd prefer to have the firewall running and allow all the traffic I normally use: Wired network + wireless network, whichever I'm connected to, or both (1) OpenVPN VirtualBox internal network Samba (for accessing shared Windows folders and sharing folders to Windows) (2) BitTorrent And everything else I use that I can't think of :) All the above works without a firewall. I thought Linux was super secure (I update regularly). Do I really need it? (1) I used the Firestarter wizard and selected wlan0 as my primary connection, now whenever I plug in a network cable, I lose all connectivity. Should I just redo the wizard for eth0, or will I then lose wlan0? (2) If it makes a difference I'm sharing a directory that I share between local users using bindfs. See my answer to Good and easy way to share files on local machine

• WWDC 2010 : Apple a présenté la nouvelle version de XCode, l'environnement de développement d'Apple

  Apple a dévoilé la nouvelle version de XCode 4 aux développeurs présents à l'édition 2010 de la WWDC. Seuls les développeurs inscrits à la WWDC peuvent actuellement télécharger XCode 4 sur leur Mac. XCode 4 nécessite Mac OS X 10.6.4 Qu'apporte-t-il de neuf ? On ne sait pas encore grand chose, vu que tout ce qui se passe à la WWDC en dehors de la keynote est sous NDA. Mais, malgré la NDA, quelques bruits filtrent sur le net. Il semblerait que XCode 4 apporterait un meilleur support pour le versionning du code. Où on aurait une interface à la Time Machine pour merger son code facilement. Meilleure intégration avec SubVersion, Git. Interface Builder ne serait plus quelque chose qui est à ...

• Web services, J2EE, Spring, DB integration project ideas - maybe data mining related?

  - by saral jain

  I am a graduate Computer Science student (Data Mining and Machine Learning) and have good exposure to core Java (3 years). I have read up on a bunch of stuff on the following topics: Design patterns, J2EE Web services (SOAP and REST), Spring, and Hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff -- over my free time of course -- to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + SVN, maven). Any good project ideas would be really appreciated. I just want to build this stuff to learn, so I don't really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus as it fits with my research but is absolutely not necessary since this project is more to learn to do large scale software development.

• Ubuntu One Sync for multiple folders, not just the Ubuntu One folder.

  - by bisi

  Hello, I may have misunderstood Ubuntu One as a service, but this is how I had pictured it. At home, I tagged a few folders with the "Sync to Ubuntu One" tick and it started uploading. Now back at work, on Win7, I installed Ubuntu One and thought I was going to be able to tick which of the backed-up folders I could download/sync to this machine. From what I gather after a little research is that whatever I would like to synchronize would need to be in the Ubuntu One folder? There is no way to do this outside of that? Thanks for confirming, or informing me whether this will be introduced in the future as an option? Thank you very much for your help on this! bisi

• Is there a very simple XML Editor/Viewer?

  - by Paul Spangle

  Part of our support job is to look at XML documents sent to our systems by our clients that have failed to load correctly. I do this by pasting the file in to Visual Studio as an XML file and VS colours it and adds line-breaks, indenting, etc. and it's then usually quite simple to spot the error and manually fix it and resubmit the document. Do I really have to use Visual Studio to do this? OK, it does the job quite well, but I'd have thought that something like Notepad++ would do the job just as well with a fraction of the machine resource usage. Is there are plugin for Notepad++ or another bit of freeware that can make XML look pretty and let me make simple edits?

• Check your Embed Interop Types flag when doing Visual Studio extensibility work

  - by Daniel Cazzulino

  In case you didn’t notice, VS2010 adds a new property to assembly references in the properties window: Embed Interop Types: This property was introduced as a way to overcome the pain of deploying Primary Interop Assemblies. Read that blog post, it will help understand why you DON’T need it when doing VS extensibility (VSX) work. It's generally advisable when doing VSX development NOT to use Embed Interop Types, which is a feature intended mostly for office PIA scenarios where the PIA assemblies are HUGE and had to be shipped with your app. This is NEVER the case with VSX authoring. All interop assemblies you reference (EnvDTE, VS.Shell, etc.) are ALWAYS already there in the users' machine, and you NEVER need to distribute them. So embedding those types only increases your assembly size without a single benefit to you (the extension developer/author).... Read full article
