Is it possible to start a job in 'nix and then immediately stopping it, without me having to enter ^Z once it starts? Please highlight shell-specific assumptions you may make. 00:08, 5 April 2007 (UTC)
^Z just sends a SIGSTOP, so starting the process and then immediately sending it a SIGSTOP with
kill will be pretty close to what you're looking for. In
bash, $!
is the PID of the process most recently started in the
background. Doing:
yes & kill -stop $!
will start a yes (which normally prints an endless series of the letter " y" to the screen) in the background, and then stop it quickly enough that it doesn't even get the first one out (though that's not guaranteed). -- TotoBaggins 02:23, 5 April 2007 (UTC)
ptrace()
, in particular the PTRACE_TRACEME option (on Linux; 0 on Solaris, ...) which literally allows you to start a process (really exec()
a file) suspended. --
Tardis 15:29, 5 April 2007 (UTC)I got an error message with the above heading. The message said: "The system DLL user32.dll was relocated in memory. The application will not run properly. The relocation occurred because the DLL C:\WINDOWS\Ststem32\HHCTRL.OCX occupied an address range reserved for Windows system DLLs. The vendor supplying the DLL should be contacted for a new DLL."
What does this mean? What should I do? -- Halcatalyst 01:08, 5 April 2007 (UTC)
I want to create a blog. My main issue, for what constitutes a perfect blog, is that it create interlinks, at least as easy, as wikipedias double brackets. Are there blog hosts which interlink this easilly? I know of wikilogs, but as for thers editing my page...that is...eh...not so much. Do most or alll blogs fit that requirement, and I don't know about it, yet? Thaddeus Slamp 20:03, 3 April 2007 (UTC).
Thank you. Thaddeus Slamp 23:36, 5 April 2007 (UTC)
I should have specified that I must not have to load anything, and this site will not do for that reason. Do you (or does anyone else) have any alternative selections? Thaddeus Slamp 18:56, 10 April 2007 (UTC)
Is there a project to emulate a graphics card under openSUSE? I need it to 'pretend' to be a graphics card and put the calculations on the processor. Thanks!-- 71.195.124.101 02:37, 5 April 2007 (UTC)

if i wnted to install comcast high speed internet and i already had a modem and an install kit would i still be charged for labor by the technician just because they come and install the stuff for me.-- logger 05:41, 5 April 2007 (UTC)
What would the average labor costs be if anyone knows?-- logger 05:54, 5 April 2007 (UTC)
Incidentally, Comcast charging high installation prices is really stupid. They should offer cheap or even free installs, then make the money back in cable fees. They risk scaring off customers which could be worth thousands of dollars in profits due to this short-sighted policy. StuRat 19:02, 5 April 2007 (UTC)
Hey All,
Does anyone know the easiest way to get information on what prices things have gone for on Ebay in a data format for free?
I know that you can perform a search using "Completed Listings Only", but I was hoping to get it in data format. I know Ebay offers "Marketplace Research", but I'd rather not pay for data (I'm a data miner!)
Is there any free 'market research'-type information on ebay sales?
I am considering just writing a VB macro to just run repeated advanced searches, locate the information within the search, and then organized it into some sort of categorical format. Has anyone done anything like this before? I did it for a local auction site for my city and it works pretty well. I don't know about Ebay though... it's pretty big. It will either take a looooong time or my IP may get banned!!
Thanks!!!

After an automatic update of XP MCE edition, I get a message that user.exe has been moved to a different location in memory because of hhctrl.ocx. It says I should contact the vendor to get a more recent one. I thought I found one at Microsoft, but when I tried to install it, it said what I had was more recent. What should I do now?

Which is the printer/technology with the lowest ink consumption or, being more specific, cost per printed paper? Maybe some kind of inkjet printer? -- Taraborn 12:39, 5 April 2007 (UTC)
It all depends on the volume and the desired quality of your printouts. You can't beat an entry level inkjet and refillable cartridges for cost per sheet, if you print low volume so that the time overhead isn't a big deal. Low cost laser printers have become quite popular in the consumer market recently, which will feature sharper, more durable printouts and operate much quicker than an inkjet. Also, Phaser is a name Xerox uses for laser printers, they perform disappointingly despite my attempts to set them to 'kill'... -- Jmeden2000 17:57, 5 April 2007 (UTC)
I would expect an old dot-matrix printer to use the least ink, because they don't print solid letters, but just dots. StuRat 18:43, 5 April 2007 (UTC)

it will be just ppt presentation that should be any technical like a OS or any Softwares....like that so ineed info where do i get latest
I suggest that you get a copy of Popular Science, they always include the latest technology. Also check out HowStuffWorks.com: [1]. StuRat 18:37, 5 April 2007 (UTC)

My favourite new technology is RFID. I think it will be absolutely massive - imagine if every car was tagged with an RFID tag - and all roads had RFID receivers in the Cats-Eyes. Then they all hooked up to the net and also talked to each other. The data could be processed using some form of AI to predict where everything is heading and at what speed. It could mean no car would ever have to collide with another again! Most pedestrians are already "voluntarily" tagged with an RFID chip (its on their credit card) - so they could be demobilised if they are about to step in front of a car (perhaps a little electric shock to the knees ;o) ). Put all that info together and wow! On the down-side, Big Brother will probably want to get a piece of the action :o( Anyway, for RFID and other techy stuff, see:

My PC is always on. I have a Picasa installation that has all my photos (~2,000) all tagged and organised. I'd like the others on my LAN to be able to access a read-only Picasa-WebUI via HTTP, or something along those lines -- even like a Picasa Web Albums that's only on my LAN. Failing this, an aesthetically appealing browser-based way of sharing photos would be great. Can anyone make any recommendations? (Note: I have almost zero knowledge of PHP, MySQL and databases.) —The preceding unsigned comment was added by 202.10.86.63 ( talk) 15:48, 5 April 2007 (UTC).
I have a (SAS) dataset which has UNQ_ID, DATE, EXPENDITURE.
For each record, I require to add a variable EXP15 to the table, which stores the sum of EXPENDITURE for the rows which have same UNQ_ID, and DATE's which are within the past 15 days from the DATE in this row.
I've tried to solve this problem, but I feel my current solution can be improved. Any hint how I can write an SQL query for it will be really helpful. -- Hirak 99

hi,
i added a new article, "Realm versus Realm" and it has been removed (i think it is deleted, i can not see it anymore on wiki).
I'd like to know why. I didn't add anything against which is against any laws or rules and the data was not fake, so I don't know what did i do wrong -the article could have been removed because of that-.
Thank you for the information and for your time in advance.
All the Best,
Mark Kondor

Thanks for the fast reply. RE: Yes, that's exactly my problem. Edited it, added with "Save page" button, tried to access it from a blank tab in my browser and it was working properly. A couple of minutes later (let's say 20 minutes) when i checked back -to revise- it said page not found. Tried to search for "RvR" and "Realm versus Realm" on wiki (generic search) - no article... ps.: i think it could be possible that it hasn't been removed but was not created at all. In that case: a)what did i do wrong (selected "Start a new article..." on main page's "Did you know" section)? b)Why was i able to browse the page for a couple of minutes on wiki with a direct link to the article?
cesarb: Thank you for the info! (and sorry for the upper/lowercase typo). Now i see it says the reason is i tried to advertise something but this is absolutely wrong:
1st) RvR is really "their word" ('WAR' makers)
2nd) WAR Online, as fully and definitely a game advert is available on wiki (but that's OK imo, there are a lot of definitions like that, e.g. "Portal (computer game)"
3rd) I spent a couple of minutes searching for "RvR" (including wiki) but didn't find it: that's why i decided to create an account here and add the topic so i can save some time of other people
The question is: What can i do now? How can i complain against the decision?
p.s.: I'm open to remove the "advert feeling" parts of the definition.
(Thanks for all the fast responses and info, and so sorry, i'm really that noob :)
update: okay, sent a message to the wiki admin who has removed the article so... hopefully he will tell me what's up related to this topic.
to "Kainaw" and "CesarB": thank you again for the response, much appreciated!
Hi there,
Recently, my computer is affected by a virus (I don't know what kind of virus it is). First infected yesterday, around this time. Then, I want to turn it on again, but for some reason (which I believe it is a virus), it got on very, very, extremely slow. The computer seemed to not move. I was trying to get to Wikipedia and edit, but I struggled for few hours, and was unable to log on. Today, I was trying to get to Wikipedia again. This time, my account (You know in Windows XP, you are able to create several accounts) was not able to log on. Panicked, I used the "Guest" account, and to be delight, it works! But I really want my account back, and restore my files. Waht should I do? (Please do not suggest buying Anti-Virus CD!) Smcafirst | Chit-Chat | SIGN posted at 23:31, 5 April 2007 (UTC)
--> Please reply at User talk:Smcafirst/Requests.
If you want to you can re-install windows, it will get rid of the virus and as long as you DON'T reformat the hard drive you can get your files back by going into C:\Documents and Settings\Your_old_username_goes_here there you can acsses your old desktop and your old My Docs. It's hard thing to do but it'll get ride of the virus(if it is a virus, sound a bit like spyware or a recource hog to me) good luck -- Lwarf 09:51, 6 April 2007 (UTC)
