Anyone here familiar enough with spreadsheets to help me out? I'm using LibreOffice, on Linux [obviously!], and although I have decades of experience doing database programming, I know virtually nothing about spreadsheets. I have what I think is a simple requirement, but since I have no idea how to do it...it's not so simple.

Assume there's a spreadsheet with six fields (columns). Let's say columns 3 and 4 are the columns of interest; 3 will have whole numbers entered into it; 4 should automatically keep a running subtotal. In other words:

Code:
Column 3           Column 4
     100                100
      25                125
     250                375
     100                475
My brain isn't up to figuring this out myself right now, so any help--as in spelling out how to do this--will be greatly appreciated.

Assuming a title row, then B2 would be =sum b2

Then on C3 you would have =sum b2:b3

And on C4 you'd want =sum b2:b4

Thanks, Dngrsone, for the help. However, I'm a bit stumped.

Quote:

Where did B2 come from? Yes, there's a title row, with names like "Total" for its fields/columns.

Quote:
Then on C3 you would have =sum b2:b3

And on C4 you'd want =sum b2:b4
Huh?

By "C3" are you referring to column 3, the column having whole numbers manually entered into the fields, and by "C4" column 4 that should automatically keep a running subtotal? I'm sorry, but I'm just not seeing what you're doing.

Sorry, that was predicated on column two having the whole numbers and column three carrying the running total.

Alternatively, you could have cell D2 =c2 and then cell D3 =sum d2+c3

Moody, you're going to hate me for saying this... but I think MS Excel would be able to do this






Okay, (again, I'm using Excel)... you can make the first col. (C3) like it is.

In C4, have it run this function "=sum(B2,C1)". This has it take the value of Column 3 horizontal of it, and add it to the Column 4 above it.
This creates a running total (I think )

Hope that makes sense, I've never tried to describe excel functions on forums before.

Mom's laptop is for the fourth time already resetting her kubuntu settings to the default (stock wallpaper, default panel, all her desktop settings reset and deleted) and I have the exact same operating system, kubuntu 12.10. I never have this bug and the only difference is her machine is a Hewlett Packard high end desktop replacement laptop computer while mine is a low end Toshiba satellite. I told her she is either doing an improper shutdown, letting the battery deplete to 0% or something. She is now begging me to reinstall Windows as she keeps getting frustrated and constantly chimes "Windows wasn't this hard!" And I really don't want to break out the recovery disks!

Is the hard drive full/too many write cycles on a SSD? Are the write permissions screwed up? Perhaps just format and reinstall, my kubuntu started acting strange and reinstalling fixed it

It seems to do it on restart or when turned off then back on. I can shut it down and bring it up no problem but it happens only to her. I've lectured her many times about never shutting down Linux but she has windows habits that just won't quit. She often forgets to plug it in and the battery dies. The only time my computer forgets certain things is if shut down improperly. My guess is she is letting it run out of juice. Unlike Windows Linux forgets things like the wallpaper setting if that session wasn't properly logged out. Likewise my Android phone forgets some recent downloads if the device crashes, freezes or requires a hard reset that doesn't properly unmount the external SD card

This laptop has no other issues and is a very expensive model with beats audio and a huge hard drive. I assure you it ain't full. It isn't a SSD

Perhaps try setting up a cronjob that checks the battery level every few minutes, and if it's too low, initiate a sudo poweroff

I tried to enable hibernation but that option is greyed out for some reason. See she just forgets to plug it in and Kubuntu never warns her and she just sees it instantly shutting off. Again she chimes in 'Windows always told me! '

The laptop also never tries to use standby even it just goes to 0% of charge and blinks out

I have yet to see that--and I'm in my 22nd year of using Linux.

EVERY aspect of a user's experience on Linux is controllable by the user [or the sysadmin]. You might want to take a look at your mom's configuration files in ~/.kde/share. Again, EVERYTHING is controllable on Linux--unlike on window$--usually with plain English configuration files--unlike on window$--that can be hand-edited or can be modified via 'system settings' type menu entries in your GUI.

I'm too tired and bored right now to offer any in-depth help, so I'll leave you with this simple, but not elegant, solution: Save a copy of her ~/.kde directory somewhere safe; make sure you save it when everything's working/looking as wanted. The next time she screws things up, just copy the backup back and you're good to go. Or, better yet, have a startup command that does it automatically.

What about enabling hibernation so if the battery goes to a certain threshold her session is saved? Seems the option is greyed out in Ubuntu/kubuntu by default for some reason as my laptop also has it greyed out

Can't believe I wrote off vi(m) so quickly. After a little bit of time last night with vimtutor, I feel like this is *the* text editor.

(of course, emacs is swell, not looking for on of *those* threads )

If you've been using nano, might want to think about running vimtutor and trying it out one of these days

Considering the direction Ubuntu has been headed, and Mint is just... uncomfortable as yet, I might just go straight to Debian.

That is, if I can find the time to do anything so drastic as install a new OS on my laptop. I have one last semester of school to do, plus working full-time, et cetera.

I may end up with a new laptop before that happens. Then, I suppose, I would have to find time to install an OS, huh?

Might be worth it to double-check the power control settings in the BIOS/UEFI. If the sleep state support is off, that would explain the lack of standby-ing.

For the record, this appears to be possible:

How to enable hibernation in Ubuntu 12.04

I'm currently not in a position to confirm if this will work, but it certainly would be worth a try.

A B
1 COL3 COL4
2 100 100 B2=A2
3 25 125 B3=B2+A3
4 250 225 B4=B3+A4
5 100 325 B5=B4+A5

NOTE: If you copy B3 and pase it to B4, B5 .... Excel will keep the row/column numbers correct so the whole column works.

Here's a little tip that might save some of you some time... (not moody, no doubt she's a master at this after all her *nix experience )

So I was working with a config file, trying out some changes... so I had to take a config and change on part over and over....

cp config.conf{,.conf2}
ls
config.conf
config.conf2

sed -i 's/windows/linux/g' config.conf2

It's nice to save yourself time by using awesome utilities instead of manually editing files.

Has anyone been experiencing any lockups on Ubuntu 13.04? Can barely run some commands in terminal to get the OS set up the way I want it to before it goes all Iceman on me.

Hmm.. I haven't run 13.04 yet.. but I think I read they switched to a different... something - WM, DM, something. Mir, I think. Could be the cause?

Maybe try boot to an alternate DM and see if that helps.

Truthfully, I'm no linux guru. I know very very basic stuff about the OS. However, some google searches have led me to various possibilities for what is going on. Some suggest it could be the kernel, others say it's the GPU drivers, and another thread says it could be lightdm.

There's no pattern to how long the system stays active. It could be immediate or it could be 10 minutes. My frustration has reached the peak, so I've quit searching for answers lol, which is what ultimately lead me to this lovely thread.

I'd heard ugly things about 13.04, so I stuck with 12.04.

Now considering a move to Mint.

Are the differences that vast between 12.04 -> 13.04?

Heh, I moved on to the 13.10 pre-release myself. Turns out the GRUB setup installed with 13.04 kept trying to chainload to the Win8 partition directly when I selected Win8 (thus failing to find any Win8 bootloader code), instead of chainloading to the Win8 entry of my EFI partition. 13.10 picked everything up properly.

Also, I still can't get HDMI audio working (got an AMD E1-1200 APU, so its an ATi 7310 gpu), either on the open source Gallium driver or the proprietary AMD sets. I've heard it's a kernel issue, but.....not even the current 3.10 mainline has the audio fixed.

*Arghhhh* It seems that neither Ubuntu or Mint want to cooperate with my PC. No clue what the issue is, but both freeze right after logging in.

Want to be a tad bit more specific? What kind of PC, which version of Ubuntu or Mint, what exactly happens, what else have you tried, etc.

I actually figured out what the problem was. It finally spat out an error code, so at least I had something to troubleshoot. Turns out that it was the GPU driver. All is gravy now.

To answer your question though, there literally isn't anything else to describe. That's exactly what happened. I would log in and the system would lock up immediately. Keyboard and mouse would become unresponsive, then my monitor would turn off because no signal was being found. As for versions, it was Ub 13.04 x64 and Mint 15 x64 though.

Hehe. I just want one of the newer GTX 6-series cards, and I'll be set for a long while.

You're OBVIOUSLY not a Linux person, right? This is seriously one of the funniest--and most outrageously incorrect--things I've read in a long time.

My linux box had a 'virus' once...the hard drive wasn't feeling well a quick swap and we were back in business!

But seriously. I can't say linux viruses do not exist...but it's so rare and hard to come across one. To my knowledge, at least. Moody, care to chime on this subject?

Yeah, an actual 'virus' is extremely rare. I've never seen one. Only heard of a few (and they are quite old - circa 1997).

Now, rootkits are a different story. Those exist. But they are generally run by a compromised root account - so it's not the same.

But back to linux virus (and in turn anti-virus)... So there are actually tons of linux anti-virus software out there. Most of the free windows ones offer a linux variant... and in fact, there is the awesome ClamAV for linux too. But fun fact, these are designed to check for windows malware. Yep. Turns out, tons of malware analysis is done collected and analyzed on linux machines.

But there is a cool new trend ... cross platform 'malware'. A few years ago there was an embedded macro in OpenOffice documents that would execute a different script based on the OS you were using. Cool stuff.

TL;DR
Linux virus? Yes, but no.

Yep, I've had quite a few of THOSE 'viruses' myself.

How's this? I started using *nix in 1985. To date, I have never personally experienced a virus nor have I ever known anyone who has. As I always say, a properly administered *nix system is very, very hard to hack, or infect with a virus, or any of the other things window$ users see as normal parts of their computing experience.

I think the only real way a user (in my eyes) can get a 'virus' on Linux, is to not know what they're doing. Install a piece of software that they obtain in a questionable way, network not being secure...stuff like that, I suppose.

Although Wikipedia says there are nearly 1000 pieces of Malware for Linux. And we all know Wikipedia has never failed us

There have been a (very) few 'proof of concept' *nix viruses in labs but AFAIK none have made it into the wild. And anyway they depend on privilege escalation to do anything, which often means social engineering to get the user to accept a request/enter root password. The *nix family of O/Ses are designed to make it hard to compromise them.

And any user stupid enough to do that shouldn't have root's password in the first place!

Exactly, and even if a [normal, non-root privileged] user manages to allow something in, it can't bring down the whole system...unlike window$.

Been running OpenSuse 12.3 KDE and loving it. Its been my main goto here the past month or so. This evening I found something else I like about it I can't say works in other Linux Systems but it actually give me a MTP so I can view files on my Droid Devices. I can access both Internal and External SDCARDS with no problem. What a wonderful find for me. (Note this does not appear to work with the Latest Mageia 3 running KDE) I tried it with fedora 17 but not a later version.

I'm a little confused. I've been viewing files from my [Linux, of course] computers on all of my Android devices for as long as I've had Android devices. By MTP you're referring to micro$oft's media transfer protocol, yes? But what does that have to do with anything? Like I said, I'm a bit confused by your post. (Lack of sleep could be part of the problem.) How is what you're describing with openSUSE different from my Kubuntu, Fedora, Ubuntu, and Bodhi experience accessing files on my phones?

When I plug in my android into any of the other systems I have tried I don't get to view my files like i am able to do with OpenSuse now. The others would only show the camera folder and thats it. or at least for me. I guess OpenSuse has MTP built in where as others don't seem to. Mostly I use Airdroid anyway don't like the cables holding me back but plugging in my phone to the computer this eve just to charge it a bit and bam found out OpenSuse does this for me. To Me its a great find Ever since ICS I havent' been able to do this. Not that I will use it that much because Airdroid rocks but still nice to know it exist somewhere. Now if your still confused take two of these and call me in the morning

Honey, I've been doing this all along on all of my computers and Android devices. When I access my phones' file systems from any of my computers, I have to navigate to their DCIM directory--it doesn't go there by default and limit me to only that location.

Funny--I LIKE Airdroid, but I almost never use it...because I don't need to!
