• How do I install Ubuntu on an HP Touchsmart 600?

  - by user70004

  I have a hp touchsmart 600 pc series. I tried to install the lastest version of ubuntu (12.04 LTS, 64bits) but it would not install. I popped in the cd and the menu asked for a reboot. Which I did. As ubuntu was about to install(purple background with 2 symbols underneth) the screen was dark and a prompt kept blinking for like over 10 minutes. So I turned off my pc and loaded my window os. I ran ubuntu again and used the help install feature. Needless to say the same thing happen again! does ubuntu work on hp touchsmart computers?

• Problem with keyboard and trackpad on ubuntu 12.04

  - by Cdub

  Have a really strange issue with my keyboard and trackpad after installing ubuntu 12.04. It picked up both fine with the livecd and in the install, but for quite awhile now, I find when I power my laptop up (Toshiba Satellite L775D-S7132), when I hit the login screen much of the time I won't have any keyboard or touchpad. I can plug in a usb mouse and then at least restart or shut the laptop down and then keep trying until it picks it up correctly, but it's really a pain to have to do that all the time. Are there quite a few bugs related to keyboard and trackpad issues with the new version? I really want to get this issue resolved as it's a major nuisance. Otherwise, my hardware gets picked up fine. Video, audio, wlan, usb work perfectly and I don't ever have any issues with them. What's the best way to figure out the problem? Thanks in advance, C.

• How should I synchronize configurations and data across computers?

  - by lfaraone

  Imagine I have three Ubuntu computers home, laptop, beach-house. They all have the same version of Ubuntu, 10.04 installed, and are kept up to date from the repositories. I use f-spot, thunderbird, and google-chrome on all of the computers. Is there a way to keep the data and configuration in sync across them, without requiring constant connectivity for normal (non-synchronous) usage? For example, they should be usable without network connectivity, so something like NFS won't work. An ideal solution would not require manual action to start the syncing process.

• Dell pourrait commercialiser une tablette tournant sous Windows 8 début 2012, révèle la diffusion d'un document interne de la firme

  Dell pourrait commercialiser une tablette tournant sous Windows 8 début 2012, révèle la diffusion d'un document interne de la firme Il y a quelques semaines, Microsoft révélait que la prochaine version de Windows supporterait les processeurs ARM. Une nouvelle qui a ravit tous les accrocs à la mobilité, une tendance sacrément dans l'air du temps. D'après des documents internes à Dell, qui sont sortis de leur cocon pour atterrir sur le Net, le constructeur plancherait sur une tablette basée sur Windows 8. Et cet appareil, répondant au nom de code de "Peju", aurait même déjà une date de sortie, fixée au premier trimestre 2012. La roadmap évoque une mise sur le marché dans les trois premiers moi...

• Profiling Startup Of VS2012 &ndash; JustTrace Profiler

  - by Alois Kraus

  JustTrace is made by Telerik which is mainly known for its collection of UI controls. The current version (2012.3.1127.0) does include a performance and memory profiler which does cost 614€ and is currently with a special offer for 306€ on sale. It does include one year of free upgrades. The uneven € numbers are calculated from the 799€ and 50% dicsount price. The UI is already in Metro style and simple to use. Multi process, attach, method recording filter are not supported. It looks like JustTrace is like Ants a Just My Code profiler. For stuff where you do not have the pdbs or you want to dig deeper into the BCL code you will not get far. After getting the profile data you get in the All Methods grid a plain list with hit count and own time. The method list for all methods is also suspiciously short which is a clear sign that you will not get far during the analysis of foreign code. But at least there is also a memory profiler included. For this I have to choose in the first window for Profiling Type “Memory Profiler” to check the memory consumption of VS.  There are some interesting number to see but I do really miss from YourKit the thread stack window. How am I supposed to get a clue when much memory is allocated and the CPU consumption is high in which places I should look? The Snapshot summary gives a rough overview which is ok for a first impression. Next is Assemblies? This gives you a list of all loaded assemblies. Not terribly useful.   The By Type view gives you exactly what it is supposed to do. You have to keep in mind that this list is filtered by the types you did check in the Assemblies list. The By Type instance list does only show types from assemblies which do not originate from Microsoft. By default mscorlib and System are not checked. That is the reason why for the first time my By Type window looked like The idea behind this feature is to show only your instances because you are ultimately responsible for the overall memory consumption. I am not sure if I do like this feature because by default it does hide too much. I do want to see at least how many strings and arrays are allocated. A simple namespace filter would also do it in my opinion. Now you can examine all string instances and look who in the object graph does keep a reference on them. That is nice but YourKit has the big plus that you can also look into the string contents.  I am also not sure how in the graph cycles are visualized and what will happen if you have thousands of objects referencing you. That's pretty much it about JustTrace. It can help the average developer to pinpoint performance and memory issues by just looking at his own code and instances. Showing them more will not help them because the sheer amount of information will overwhelm them. And you need to have a pretty good understanding how the GC and the CLR does work. When you have a performance issue at a customer machine it is sometimes very helpful to be able a bring a profiler onto the machine (no pdbs, …) and to get a full snapshot of all processes which are in the problematic use case involved. For these more advanced use cased JustTrace is certainly the wrong tool. Next: SpeedTrace

• Are the Ralink RT3090 drivers incompatible with Ubuntu 10.10?

  - by xd1936

  Ralink Technology publishes their drivers in source code form on their website here. When complied with make and make install in 10.04, the drivers worked well in 32 and 64 bit versions of Lucid. However, when compiled for the 64 bit version of Maverick, it does not work at all, and 32 bit Maverick, it works but randomly disconnects. Both versions of Maverick say "[Proprietary] Driver is activated but not in use" in the Proprietary Drivers dialog. Do the drivers just need to be updated? Is there an easy fix?

• Gaming with ATI open-source drivers

  - by user7174

  I have recently bought humble bundle 2 ( http://www.humblebundle.com/ ). Is there a way to run Braid using ATI's open-source drivers? The game always crashes. When do get it to start in windowed mode once i go to the first level it will crash. I am using the lastest version of Braid (ST3C ignored) When I use the proprietary drivers Braid works flawlessly and World of Goo performance is increased. However there is terrible screen tearing with the ATI propritary drivers. So my question is: How do I play Braid if I want to use the proprietary drivers?

• Closing lid does not suspend laptop

  - by fgysin

  I'm on a Lenovo T400 laptop. In the past I had suspend problems on every second version of Ubuntu (at least it feels like it), but in 11.04 it was working perfectly. Now, after the upgrade to 11.10 closing the laptop lid does no longer initialize suspension. When I choose 'Suspend' from the shutdown menu it works perfectly, so this does not seem to be an issue with suspend itself. The options in System Settings>Power are of course set to suspend in case of closing the lid (both for battery and AC poer). Note: I have no idea if this is of any importance, but I'm running the gnome-session-fallback stuff, as I just hate the Unity desgin.

• Installing linux on OCZ RevoDrive3 x2

  - by user2101712

  First of all, here is the configuration of my computer: Motherboard: Asus H87Plus RAM: Corsair Vengeance 32GB Processor: Intel i7 4770 Drive: OCZ RevoDrive 3 x2 (240 GB) (OCZ Revodrive3 is a PCIe module) I am trying to install the latest version of Ubuntu Desktop (13.10). The problem is that in the UEFI (bios) the drive shows up as a 240 GB drive, but in the Ubuntu installer it shows up as two 120 GB drives. If I install Ubuntu in any of these two drives, it never boots. The screen flickers a few times and comes back to the UEFI menu. I have tried reading up and have come across information that the drive has a "fakeraid", and the solution is to use dmraid. However, when I give the following commands in the terminal (from live CD): # modprobe dm_mod # dmraid -ay it says: no raid disks. And the following command: # ls -la /dev/mapper/ just shows /dev/mapper/control How can I install Ubuntu on my computer? what is the correct method?

• Computer crashed during 3.0.0.17-generic kernel upgrade

  - by Z Swim

  My computer crashed (due to heat) during the update process for the 3.0.0.17-generic kernel upgrade. My computer will not boot ant all in 3.0.0.17 now and 3.0.0.16 is unstable (wireless networking doesn't work, also crashes often). I found the boot to previous versions tool at start up and the last stable version is 3.0.0.15-generic. However, my computer still thinks that it has 3.0.0.16-generic and 3.0.0.17-generic, even though both of these versions are broken. Is there anyway to force a reinstall of the 3.0.0.16-generic and 3.0.0.17-generic kernel updates from 3.0.0.15 and associated other updates?. (Without having to do a full reinstall?) I am running ubuntu 11.10. Thanks!

• SQL Concatenate

  - by Bunch

  Concatenating output from a SELECT statement is a pretty basic thing to do in SQL. The main ways to perform this would be to use either the CONCAT() function, the || operator or the + operator. It really all depends on which version of SQL you are using. The following examples use T-SQL (MS SQL Server 2005) so it uses the + operator but other SQL versions have similar syntax. If you wanted to join two fields together for a full name: SELECT (lname + ', ' + fname) AS Name FROM tblCustomers To add some static text to a value: SELECT (lname + ' - SS') AS Name FROM tblPlayers WHERE PlayerPosition = 6 Or to select some text and an integer together: SELECT (lname + cast(playerNumber as varchar) AS Name FORM tblPlayers Technorati Tags: SQL

• Geek City: sp_cacheobjects for SQL Server 2012

  - by Kalen Delaney

  In a post about 4 1/2 years ago , I gave you my version of a replacement for the old pre-2005 pseudotable syscacheobjects . I called it sp_cacheobjects and created it as a view in the master database. With the sp _ prefix, the view can be accessed from any database. When testing this on SQL Server 2012, I noticed that I almost always got a lot more rows back than I was expecting. Even when I added a WHERE clause to limit the database to only the database I was working in, I STILL got way to many...(read more)

• Avoid penalties for duplicate (multilanguage) shared hosting

  - by Dave

  My concern is about SEO. Now let me explain the scenario. I am making a 3 languages website. The development is alright, but I was targeting local customers with one domain, and international (english version) with another. Eg: Local http://www.minhalojadesapatos.com.br (this is not the real website, just example!) Other http://www.myshoesstore.com.br Both domain point to exactly the same hosting and content, but when user comes through local domain, default language is set to portuguese, otherwise, default is english. Language handling on backend uses PHP Sessions and cookies, so with just a click users can change content language. How to avoid being SEO-penalised in this context? (yeah, I was hungry when focusing market for choosing two domains but the activity really needs that, it is a travel agency).

• How to set up Google Chrome as default browser in Xubuntu

  - by mpm

  I use Xubuntu 12.04. I uninstalled Firefox and now use Google Chrome version 19.xxx. To solve this problem, I tried: galternatives the "default apps" under settings and sudo update-alternatives --config x-www-browser Neither of these worked. Does anybody have an alternative solution for this? -- Solution: I used the "sudo gedit /usr/share/applications/defaults.list" tip from ??? and searched for firefox in the whole document! Everytime I found "firefox" I replaced it with "google-chrome.desktop". I also used the "default apps" menu to change it to google-chrome. And now it works.. I hope it helps some other ;-)

• Stateless game design

  - by L. De Leo

  I'm facing a challenge understanding how to program a web version of a card game that is completely stateless. I create my object graph when the game begins and distribute cards to PlayerA and PlayerB so I lay them out on the screen. At this point I could assume that HTML and the querystring is what holds at least some of my state and just keep a snapshot copy of the game state on the server-side for the sole purpose of validating the inputs I receive from the web clients. Still it appears to me that the state of the game is by its nature mutable: cards are being dealt from the deck, etc... Am I just not getting it? Or should I just strive to minimize the side-effects of my functions to the objects that I take as my input? How would you design a stateless card game?

• APEX-Region "Karte" mit eigenen Karten ausstatten

  - by carstenczarski

  Seit der Version 4.0 bietet APEX den Diagrammtyp "Karte" an; dieser erlaubt die sehr einfache Integration von Karten in eine APEX-Anwendung. Die Darstellung der Karten basiert, wie für alle Diagrammtypen, auf AnyChart. APEX bietet zwar eine Vielfalt von verfügbaren Karten an, in der Praxis dürften diese jedoch selten ausreichen - zu verschieden sind die Anforderungen; für Deutschland werden nur zwei Karten angeboten. Oft ist es also nötig, den APEX-Lieferumfang um eigene Karten zu erweitern. Wie das geht, beschreibt unser aktueller Community-Tipp.

  I'm having a really big problem with installing Ubuntu on my computer. It seems that when I try to install from BIOS from the CD, nothing happens, and when I say nothing happens it boots up my computer like usual.
