Which partition scheme should i use?
Hello guys (and maybe ladies), i am new to Linux and i have decided to set sail on an epic quest: Setting up a Linux desktop with Arch.
I have installed Arch few times on the main victim machine and on another laptop too, so i'm pretty much confident with most of the commands i run (through the forum captcha got me puzzled for a while, lol).
So, into the topic, i would like to gather suggestions on what partition scheme should i use, i have an 120GB Intel X25-M SSD i intend to install Arch on, RAM amount is 6 gigs.
From the wiki and forum reading i done so far, i came up with the following SSD torture plan:
/dev/sdb1 -- root -- 25GB
/dev/sdb2 -- /var -- 15GB
/dev/sdb3 -- /home -- rest of the space, somewhere around 80GB
All are btrfs.
I intend to install swap later on a rotating storage, or not.
Arch wiki @ Btrfs :
"Do not use this filesystem yet unless you know what you are doing and are prepared for potential data loss."
I may not know what i'm doing, but as long as using a misconfigured system wont render my SSD a piece of salvageable material, i'm ready to test experimental/unstable/new features (except systemd) for the pursuit of performance, the precious bits of data are backed up and i'm ready to hold the wrench
Sorry for the long reading, any suggestions on the partition scheme? should i not use btrfs after all?
Bizzare, awkward or just special suggestions will be appreciated too, thanks in advance.
And here's a third smile

I want to add my (different) setup here, too, to help you decide. My setup is:
/ 15G
/boot 100M
/var 10G
/home rest(91G)
I also have two systems with seperate /usr, as I like it that way now, but that's a little advanced (though not hard, so if you want to learn, try it). Also, if you want to encrypt your system, make boot seperate as suggested by silentsnake.
But my most important suggestion if you like to experiment: use LVM. Allocate only limited space to your partitions. I suggest: 10G each, except 100M boot, if you keep /usr seperate, use 3G for root. LVM is really cool and very easy and highly flexible. And it gives you the possibility to add, remove and shift sizes around as you please - I love it! Just leave the free space you have hanging in the volume group and add it where it is needed. If you are feeling lucky or highly flexible, make /boot an LVM partition, but I don't recommend it: I do not see any benefit, only some possible issues.
As for swap: 6G is enough RAM - if you need swap later (e.g. hibernation) use a swap file (I don't, but I hear it's possible).
On your file systems: If you are into experimenting, you can choose whatever you like, but I doubt you will be unhappy in any way if you just choose ext3 (though Reiser seems like a nice idea for var).

Which file type should I use and how I use it?
Hello!
I need to create a file with some data that has been inserted manually.
In this file, for example, there are:
ProjectName1: string1, string7… string10, date1
ProjectName2: string11, string15… string20, date2
ProjectNamek: string 100, string 116 … string 140, date1
I know only one thing: one of the strings.
What I need to find in the file:
I need to find the string at one of these rows and get its ProjectName and date.
For example: if I have string15,
I should find string15 in the file, and get its ProjectName and date:
ProjectName2, date2
Which file type should I use and how I use it? What is the best solution?
Thanks!800512 wrote:

(ie:
1. ProjectName always starts the line and ends with a ':'.
2. The rest of the strings on the line are separated by ", " and will never contain ", "
you might also want to have a look at String.split().

Type exactly whats on here on your settings.
Procedure:
1- Turn on your phone
2- Get paperclip take out tray and put your non working sim card in- T-moble and simple mobile sim cards work great for me on this venture.
3. Goto Settings>General>Cellular>Cellular Network
At this point its very critical that you do this fast, Once you change the sim card to your net 10 the option Cellular Network will only stay on for a few seconds while it's searching for service. You will need to click on cellular once the Net10 sim card is in and click on Cellular network again.
4. Get your paperclip take out the tray put in the Net 10 sim card
5. Goto Cellular>Cellular Network while it's searching for service
6. Type in your settings that I list above
7. Scroll back to your main setting (Do not press your Home Button)
8. Once you see your service up and running try out your web and send a picture message it should work.
9. If it does'nt work you mistype one of the settings, it has to be exact or it wont work.
10. Do the process all over again
Keep this information and the sim card away for a later date in case you lose your setting I have'nt turned off my phone or let my battery die to find out if I lose my settings. One thing for sure I lost it when I update to the IOS 6.0.1. -
Which audio format should I use on my memory stick?

Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
1. Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak 2 or Vista. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
2. Parallels Desktop for Mac and Windows XP, Vista Business, or Vista Ultimate. Parallels is software virtualization that enables running Windows concurrently with OS X.
3. VM Fusionand Windows XP, Vista Business, or Vista Ultimate. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
4. CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not yet fully developed for the Mac - some features are not yet implemented - but it does work otherwise.
6. Last is Q. Q is a freeware emulator that is compatible with Intel Macs. It is much slower than the virtualization software, Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system.
See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion.
Boot Camp is only available with Leopard. The Boot Camp Beta that was used with Tiger has expired and is no longer available for use. So contrary to the other poster's comment, Boot Camp isn't truly "free." You must purchase Leopard to get it. -
I buy apps in my iPhone using different Apple ID. Which Apple ID should I use to authorize the computer when sync iPhone with iTunes?
Hi again,
After a little further research, it appears that you would need to create separate iTunes libraries in order to be able to continue to purchase and download previously purchased items on the same computer, for two different Apple IDs. Sorry - but my husband and I have had the library we sync with authorized for so long, that we have not run into this issue, but it appears that you will get an warning when you try to authorize the second ID on the same computer, indicating that another ID is already associated with it.
So, you will probably have to set up separate iTunes libraries for each ID:

Sorry for any confusion - hope this helps!

Which uesr exit should I use by such a case
The requirement is to send the email to manager when anyone create or change the Material data by using MM01/MM02.
The function of sending email I have done but I don't know which user exit should be used to call the function.
I have tried MGA00001 >EXIT_SAPLMGMU_001>INCLUDE ZXMG0U02 and writed some code in the ZXMG0U02. (ex: break point) .but when I modified the Material and saved,the stop does not appear. whether I used a wrong user exit?You can use enhancement MGA00001 (industry only) for this.
For more information, see the documentation for the following components assigned to this enhancement:
Function Calls :
EXIT_SAPLMGMU_001
Enhancement Number : MGA00001
If you want to send a mail for only material creation/ extend then you can you the badi BADI_MATERIAL_REF.
we don't have BADI 's for Change the Material master records.
If you want to send a mail for MM02 also then you can go for the Enhancement ' MGA00001' under the function module 'EXIT_SAPLMGMU_001'.
Thanks

Which color profile should I use?
I'm getting into doing some freelance graphic design, and I've been playing around with my awesome new C2D Macbook Pro. I am wondering, which color profile should I use? It's set on Color LCD, but I'm wondering about Adobe RGB or Apple RGB would those be better?
Thanks!I personally am a fan of the sRGB on the Mac. I think the blue comes out very nice when comparing it to the others.

Which HttpClient class should I use for Universal apps?
Hi,
I am developing a Windows Universal app for Windows phone and WinRT in C# and I would like to know which HttpClient class should i use? Should I use the System.Net.HttpClient or Windows.Web.HttpClient?Because the System.Net.Http and System.Net.Http.Headers namespaces might not be available in future versions of Windows for use by Windows Store apps. It is stated in the official documentation on MSDN here:
https://msdn.microsoft.com/en-us/library/windows/apps/xaml/dn469431.aspx
"Starting with Windows 8.1 and Windows Server 2012 R2, use Windows.Web.Http.HttpClient in the Windows.Web.Http namespace and the related Windows.Web.Http.Headers and Windows.Web.Http.Filters namespaces instead for Windows Store apps."
And the Windows.Web.Http.HttpClient class is supported from Windows Phone 8.1, Windows 8.1 and Windows Server 2012 R2:
https://msdn.microsoft.com/en-us/library/windows/apps/xaml/windows.web.http.httpclient.aspx
Hope that helps.

Which kernel module should I use for Marvell Yukon 88E8001?
Which kernel module should I use for Marvell Yukon 88E8001?
a. sky2
b. skge
c. sk98linI found this in the kernel''s /driver/net/Kconfig:
config SKGE
tristate "New SysKonnect GigaEthernet support"
depends on PCI
select CRC32
---help---
This driver support the Marvell Yukon or SysKonnect SK-98xx/SK-95xx
and related Gigabit Ethernet adapters. It is a new smaller driver
with better performance and more complete ethtool support.
It does not support the link failover and network management
features that "portable" vendor supplied sk98lin driver does.
This driver supports adapters based on the original Yukon chipset:
Marvell 88E8001, Belkin F5D5005, CNet GigaCard, DLink DGE-530T,
Linksys EG1032/EG1064, 3Com 3C940/3C940B, SysKonnect SK-9871/9872.
It does not support the newer Yukon2 chipset: a separate driver,
sky2, is provided for Yukon2-based adapters.
To compile this driver as a module, choose M here: the module
will be called skge. This is recommended.
Looks like your module is "skge" -

Which wattage adapter should I use with the composite cable with my iPad?
Which wattage adapter should I use with the composite cable when connected to my iPad while watching T. V. .
Ultimately, use the power adapter that came with the iPad. But you should use any USB based power adapter that has a 10 watt/ 2 amp or higher power rating. Look close when buying a thrid party adapter, if it does not specify 10 watts/2 amps it is a lower 5 watt/1 amp charger that will not work.

Which jdbc driver should be used for sqlserver 2000 and where to put it.
hi all,
My odi is 11g. I met the error infor "Could not load JDBC driver class [com.microsoft.sqlserver.jdbc.SQLServerDriver]" when i tried to connect to a sqlserver2000 database.
The questions are:
1. which jdbc driver should be used for sqlserver 2000?
2. which folder to put it in?
3. how to set the physical topological "Microsoft Sql Server" to use this jdbc driver?
failed tries:
i downloaded the driver "SQL Server 2000 Driver for JDBC Service Pack 2" and put it in the following folders:
1. .../oracledi/drivers, and set this path to CLASSPATH.
2. .../oracledi/userlib didn't exist, i created it and put the driver in.
3. .../oracledi/agent/dirvers, in which a readme file exists and told me to put drivers in this folder.
All these works were not useful. when I start odi.sh and try to connect to sqlserver2000 database, the same error infor came up.
my environment is:
os: Linux 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

ODI: 11g, installed in /users/oracle/odi/
please help me,thanks a lot.

帖子经 Jun编辑过Hi,
You should check which JVM version is required by that version of the driver, I think the 2.x versions require a 1.6 JVM
What error are you getting? If it is the "com.sunopsis.sql.c: No suitable driver", it indicates it can't find the jar file (sqljdbc.jar) for the driver you specify.
Drivers folder in ODI 11g is under
C:\oracle\product\11.1.1\Oracle_ODI_1\oracledi\agent\drivers.
if you are using the standolone version
On windwos :
C:\Documents and Settings\<userName>\Application Data\odi\oracledi\userlib
on linux
$HOME/.odi/oracledi/userlib
Have a read of :- http://download.oracle.com/docs/cd/E14571_01/core.1111/e16453/install.htm#CHDBIFAJ
