Why is there only one kernel by default?

i just noticed this when trying out ubuntu. every time you upgrade or install a new kernel, they create a completely new initrd image, config file, and kernel image, and store them in /boot. so...in the event that a new kernel screws up, you can always roll back to an older kernel.
why doesn't arch do something like this?

Moo-Crumpus wrote:McQueen, I can't follow your arguments. If managing your own system had such a weight, then udev and hotplug, initrd and one kernel for all, hardwaredetection and hwd would break the rule, wouldn't it.
That's untrue. Doing something automatically does not imply that it removes control from a user. If it did, then there would be no rc.d scripts, you would have to put everything in rc.local. Hardware detection is the same - you have the option of not using it.
There is not a single app you can name that does not do something automatically. How would you like it if firefox failed on first start with "no profile directory, please create it first" or if your IDE controller modules failed saying "hey, I found some drives, but you didn't specify names for them when loading me - too bad, failing....".

Why is there only one automated audio fader at head and none at tail of some audio clips?

When I select "Show audio animation," top left of an audio clip, on some sections I have two knobs... one at the head for fade in, and one at the tail for fade out. Why is there only one on some of the audio clips and not both? I've set up the clips the same, regarding audio animation, and some have faders at head, but not tail. How do I make another fader at the tail of a clip? Or why doesn't it automatically behave like the other audio clips that DO have two faders? I don't know what I'm doing to make them act differently.
Thanks,

Tom,
Thanks for reply. I'm attaching screen shots. For some reason my pointer didn't show up with a normal screen grab. Don't understand. Anyway, several versions are attached. There isn't one hidden on the right beyond the frame that pops out when I put my pointer there (or any tool). Strange.

Why is there only one Operating Concern defined in GBI?

Hi all,
I have the following question: when looking at the CO structure of the GBI case study, why is there only one, global operating concern defined? According to the definition of an OC, it is the level whereupon profitability analysis is performed. So why is in GBI that has two very distinct business areas not at least two OCs defined (one per business area), if not more (per product)?
As a follow-on, what is then the relation between OC and Controlling Area? I am looking for a plain English explanation that I can also use for teaching purposes.
Thank you in advance for reading!
Regards,
Gerhard

Hi Gerhard,
I hope my reply is not too late.
I agree with you. Profitability analysis is typically done at a detailed level - by market segments, which may be defined by geographical segments, customer groupings, product groupings, salesforce grouping, etc. CO-PA does support profitability analysis at such detailed levels.
After defining an operating concern and activating it, the system generates a series of database tables for the operating concern. I took a screenshot of the (partial) structure of the "master" table for the global GBI operating concern, GL00, from the GBI 2.2 system I am using, below:
As you can see, with such a table structure, CO-PA is capable of capturing profitability information at a very detailed level for reporting and analysis.
You may also notice that operating concern is not a field in the table. The reason is, the entire table (as well as its related tables in the same series) is used only for operating concern GL00. Its name is even hard-coded in the last 4 characters of the names of these tables. When CO-PA reports are executed in SAP ECC, they retrieve data from only one series of tables, i.e., only data of only one operating concern can be reported.
Back to your question: Why is there only one operating concern and not two? The wisdom of defining one global operating concern is that profitability data of both controlling areas (Europe and North America) will be updated into the same series of database tables and reported together. If there had been two separate operating concerns for the two controlling areas, there would have been two series of database tables, making profitability analysis across the two areas difficult, if not impossible.
Let me know if you need further clarifications.

Why is there only one phone available? Where can I get it?

I arrived at the main site for Firefox by typing www.getfirefox.com in the address bar of my Firefox browser, because I wanted to see if I have the latest version of Firefox. I saw the message that says, "Congratulations, you have the latest version!" Then I saw there is a Firefox OS, so I clicked on that. I eventually followed the link to get a Firefox OS phone, but to no avail. The eBay listing is expired. Yay!
Finally I got to the page that lists, with pictures, the various Firefox OS phones. Only one says it is available, and when I click on that one, to try to get it, I get to a similar page at eBay, where it says the listing has expired. Wow. This doesn't give me a lot of confidence in the security of Firefox. I wonder why it told me that I have the latest version of the Firefox browser installed, when mine is 31.0 and the latest is 33.0.1, and if there is only one Firefox OS device available, and the link on the Firefox site takes me to an expired eBay listing, I don't think I'll be trying to get a Firefox OS device any time soon.
Does anyone here have any suggestions for me?

Hi Scottelly,
You can update the Firefox browser in your computer by following these steps:
* [[Update Firefox to the latest version]]
Regarding Firefox OS, it's a mobile operating system that is available on phones around the world. Here are all the devices currently available (please keep in mind that some of these devices are only available in some countries):
* [https://www.mozilla.org/en-US/firefox/os/devices/ Firefox OS devices]
There is also the Flame Reference Device available for purchase, which is recommended for developers wishing to create applications or develop for Firefox OS:
* [https://developer.mozilla.org/en-US/Firefox_OS/Developer_phone_guide/Flame Firefox OS Flame Reference Device]
If you have issues finding a phone, or with a link pointing to an expired Ebay listing, please let us know so that we can investigate.
I hope you find this information useful. Please let us know if you have any questions.

Why is there only one forum category called Apple TV under Apple TV Forum?

I don't know how long this category existed, but isn't it strange that we have a product forum and sub-category, both the same name? Unless Apple is planning to come out with a new Apple TV and so the current forum will address the old Apple TV and there will be a new Apple TV Platform 2.0 category. Apple announced that they are coming out with new product releases today during their quarterly results today and will it contain a new version of Apple TV as well? With support for 30fps and 1080p videos?

I have a simple question.
I just bought the Apple TV ~ 160 gig.
I want to store all my movies there (mp4)
Is it possible to keep them stored in Apple TV or do i need to keep them in my computer harddrive too?
If so what is the difference between 40 gig and 160 gig if i cannot store anything there?
Cheers ^^

Why we have only one log writer in oracle while we have more than one DB writer and archiver in oracle.

No - there is only one log writer process per instance.
Don't confuse the function of I/O slaves with the function of the log writer.

When I use the printer icon in Firefox, it is preset to 10 copies. How can I change this to only one copy by default. Thanks for any information

When I use the printer icon, in the upper left corner, it is automatically preset to 10 copies. I only want one copy by default. I can change it to one, but when re-opened, it is back to 10.

Number of copies to be printed isn't a setting that Firefox is supposed to be saving, and I have never seen a preference for that in the hidden Firefox prefs panel - about:config.
Try the '''''reset''''' described here and reset all the prefs for that printer: <br />
http://kb.mozillazine.org/Problems_printing_web_pages#Reset_printer <br />Make sure to restart Firefox before seeing if doing this '''reset''' fixed your problem.
If that did fix your problem, please click the '''Solved It''' button next to the answer that answered or solved your Firefox support issue, '''''it appears when you are logged in''''', so this thread gets marked as '''Solved''' to help other users who may have this same problem.
If that didn't solve your problem and it still defaults to printing 10 copies of everything thru Firefox, please open '''Help > Troubleshooting Information...''' and use the '''Copy All to Clipboard''' button and then paste that information into the '''''Post a Reply''''' box here.
It is going to be a real long list, but all I really need to see is the ''' print.''' preferences, so you could paste '''All''' that information into a text program like WordPad first, edit out the information that I don't need to see, and then '''copy''' the remaining information and '''paste''' only that information in to the '''''Reply''''' box here.
I wonder if there might be a pref that I have never seen, but I truly doubt it. That "number of copies to be printed" has never been "stuck" for me on any program in Windows, on any PC I have ever used, with any printer / print drivers.
The only time I have ever seen a "print dialog box" default to more than 1 copy was with a work application where the program being used was set to force 2 copies of some specific forms to print 2 copies all the time - one to be given to the "customer" at the end of the job for their records of the service call and one for the "employee" to get a signature upon completion of the job, to fax into the home office for job documentation as completed successfully and for payroll purposes so they would get paid for that service call.

Why I see ONLY one db on my node ?

I have a PC (NT node) with 1 oracle server 8.17 , on the server I have 2 databases (db1 , db2).
With OEM I see the node ... but ONLY db1 !!!
Suggestion ? (off course I refresh node and db2 works ok)

In the iPod's About menu, the disk size is reported as slightly less than the technical specifications, this is normal for all drives. The same is true if you look at the size reported for your own computer hard drive. My 300 GB hard drive is reported as 279.36 for instance. There is also a proportion of the space on your iPod taken up by the operating software but the difference is mostly down to how the size is measured by the manufacturers.
Why the difference? Most hard disk manufacturers measure disk size this way: 1 MB = 1 million bytes (1000 * 1000). A 4 GB disk, therefore, is one that holds 4 billion bytes. Computers, including Windows computers, Macintosh computers and iPod, measure disk size this way: 1 MB = 1 048 576 bytes (1024 * 1024). The difference in these two calculations is what causes the drive to appear as 3.7 GB on a computer, but actually be a 4 billion byte disk.

Why is there only read(byte[]) & not read(int[])

I'm trying to read large raw images using the RandomAccessFile. Different images are of different types, some are uInt8, some are int8, some are int16, uInt16, float, etc. The only way I know to read them fast enough is by reading an array of bytes, and then putting the bits together into a new array of the desired type, e.g. shifting and adding to the bytes.
I'm sure there's a clever way to read different types really fast... How?

Well... Is there any possabilities to create a new
int[] array that is "pointing" at the same memory
allocation as the byte[], just as you can do in C or
other languages with pointers?
Nope, Java is type safe.
It would be easy if I could make the compiler
interpret the byte[] as an int[]... Suggestions?
Create a java.io.DataInputStream to read from a java.io.ByteArrayInputStream that reads from your byte[] is one option:ByteArrayInputStream byteStream = ByteArrayInputStream(anArrayOfBytes);
DataInputStream integerStream = new DataInputStream(byteStream);
int firstInt = integerStream.readInt();
...If you need random access to an int array maybe you need to create the array first and the read ints to it...

Why are there only 80 emoticons?

Yes I know there is currently no options for more emoticons and that we have to use the 80 bland ones we have now.
Why is Microsofit limiting my options? What kind of company is this? Where is the innovation? Yes, I know emoticons are not advancing our society anymore than unwrapped Starburst minis are. I think this is ridiculous. It's 2014, and I'm tyring to add a little
spice to conversations with my coworkers. I'm being serious. Can you not find some lowly hourly wage intern and have him code emoticons?
One of the emoticons is a soccer ball. NOT ANY OTHER TYPE OF BALL. A SOCCER BALL. That's not even our nations favorite past time? When will that emoticon have a use? I didn't even use it during this years World Cup to put that into perspective. But this
is not about me. It's about giving people more options. If this isn't the medium for me to voice my suggestion, then please give me one.
Can someboy just push this up the chain of command? Next time there is a suggestion box, mention that millions of Lync users all over the world want more emoticons. Its not that hard to do. Listen to your customer base. It's a very simple concept. Does anyone
around you study business? Marketing? GIVE THE PEOPLE WHAT THEY WANT.

Why is there only a 10-number block limit on incoming calls?

Verizon has failed to stop many call violations of the Do Not Call laws, particularly allowing callers to fake their ANI identification. Except for legitimate reasons, such as law enforcement, domestic violence, or other exceptions, no call should be completed that does not match the actual origin. That aside, we who continue to be awakened from sleep, dinners interrupted, and run to the phone only to find the call is another pan handler violating the law, we have to take action into our own hands. Why is it then, that Verizon has a limit of only 10 numbers that can be blocked? And why can we not block entire area codes and exchanges so a boiler room cannot keep changing numbers with the same area code?
Please, Verizon, give us more options to manage our own calls until the day you have the smart technology in place to limit illegal calls.
Solved!
Go to Solution.

Seconding what TimeVoyager states here. I have signed up for the Do Not Call Registry (for whatever good that has done) and still get at least 3-4 telemarketer calls per day. If Verizon allows us to block 10 numbers, how difficult could it be to bump that limit up to 50 or more, or better yet, provide some flexibility in blocking entire NPA/NXX combinations as the telemarketers typically have number ranges and/or frequently change their numbers to dodge the simple blocking schemes. Perfect solution for me would be a system that allows for users to manage a single list that contains white listed numbers that pass through, black-listed numbers that get blocked, ordered in priority of execution (very similar to how email SPAM blockers work). An updated interface would be a boost too (as the current one is a little clunky) so that users could very quickly add/edit/delete numbers from the tool itself and even an option to white/black list numbers directly from your call log. The current 10 number limit is not enough. I am at the point where I am questioning the value of my land line as the inconvenience of the unwanted calls far outweighs the convenience of having the line for the few times I use it for legit calls each week. Strongly considering dumping my voice plan when my bundle is up for renewal if this is not somehow addressed as again, how hard could it be for Verizon to simply increase the limit from 10 to a much large number?

Can you tell me why we play only one song at a time and stop now???????

OK....I will try to stop seething and write clearly. DL'd ITunes V8.0 which ran great for about a week. Now when I try to play from Music library it will play the first song then stop. If I try to advance using the forward button it stops playing as well. This only happens in the Music Library. Playlists function as normal. Please tell me this isn't another Apple "Enhancement". Ugh.

Are the little checkboxes to the left of name ticked? If not iTunes will not advance to the next track as iTunes skips unchecked tracks.
To check all, press ctrl & click in one of the little boxes or use select all, then right click in the selection and choose check all.
Usually this affects both the music library and playlists so I am not sure about it.

HT4847 Why is there only 5GB of Free iCloud Storage for the iOS Devices? Shouldn't the iDevices that have larger storage capacities than other iDevices, have more than 5GB of Free iCloud Storage offered?

I have a 32GB, 4th Generation iPod Touch, with only 5GB of free iCloud Storage offered. Why should I pay more for iPod Storage, when I receive the same amount of iCloud Storage as the iDevices with less iPod Storage? I understand the Marketing/Business point of view. However, it should appear that it is only logical to increase the offered capacity of free iCloud Storage to those of whom that have purchased an Apple Device with larger storage capacities.

It boils down to that is what Apple does. Just like you don't get a big computer discount if you use your computer more than I do. I don't get a better job because I'm smarter than you are. It's the way things are. You have no more entitlement to something than I do.
As for "business?" Of course it's business. Everything is business. To think this is special just to Apple is to ignore reality.
With iCloud storage we start on a level field - 5 GBs free. Thereafter, it's pay as you go.
