Happen to remove my color cartridge and test out only with my black cartridge. It worked the first time but later on every time when I selected the printer with the respective application beside the deskjet F4400 - /usr/lib/cups/backend/hp failed was displayed. I tried stopping and restarting the cupsys daemon
/etc/init.d/cupsys.d stop
/etc/init.d/cupsys.d start

I couldn't get it started so following the instruction at http://chenjie66.wordpress.com/2011/03/26/usrlibcupsbackendhp-failed/ which did work.

I don't know whether the gui equivalent of such resolution is available or not.

Retro Tracing - slmodem(USB V92 56K) with driver

To be precise its Krypton Modem v.92 56K USB
The device looks sleek.Driver can be found here http://sourceforge.net/projects/gnumen/files/
Yep its a dial-up modem running on 2.4 kernel. It was run on weendoz first then got the driver from www.smlink.com(site not found now) for GNU/Linux. Use to make use of the driver in Redhat 9.0 and ran like it should be.. when speed was not of concern than the device(s) made to run on GNU/Linux(At that time compiling the src to activate the device was considered c00l, now its almost apt/rpm).Wanted to see when I did it and the date was 2006-2007.

The Redhat 9 was not also automounting the usb pen drive. So these steps helped in recognizing the device and mounting it.

accessing a site slowing things down ?

pretty unusual, observed that opening up a site (to be precise android.com) made my box to use up almost all of the cpu and the browser started to respond slowly. the screen shot of the resource utilized is given below. Why in the name of god is such thing happening.

It is possible to get answers to all the questions but when it comes to implementing it, it's said that its not pragmatic.
List of  questions
  • why have a social structure when it promotes anarchy?
  • why believe in good via bad references?
  • why get married when life after marriage is miserable?
  • why have kids when you have to beat them up?
  • how can a non-thinking kid grow up to become a non-thinking parent?
  • Is parenting just about giving birth to kids?
  • how can a parent with shallow thinking guide a kid (which is still raw) to think deep?
  • When the parents are/were wrong do they confess to their kids they were wrong?
  • Are you superstitious?
  • why perpetuate myth/superstition in connection with god?
  • why is a workplace just another political scenario?
  • why can't people just mind what they have to work with?
  • why do people talk junk when they can refrain from doing so?
  • why do humans especially females cry when things go wrong?
  • Does crying solve any problem, if not then why do people cry?
  • why humans don't take responsibility, this include blaming too?
  • why most people can't get addicted to good things? like learning new tech/science?
  • why most humans are always attracted to do bad?
  • why is government formed. its for the people or are people for the government?
  • if people created government for its security then why government needs security from people?
  • why are politicians such scoundrels(except few good ones)?
  • why does material instigate us to work and not the work that instigates us to work?
  • Is there anyone willing to work without benefits? if so how?
  • why vote when the options given are useless?
  • isn't it a form of dictatorship in democracy, where only one time people are allowed to vote and the rest of their 5 years or whatever is out of  their hands?
  • Does society breed mediocrity?
  • do humans live to breed as an ignorant species or breed as an intelligent species?
  • why do parents misconceive that they know everything?
  • what are the basic needs of an individual and how to standardize it?
  • why have god when it promotes superstition?
  • if government earns its revenue through beverages how is that beverage bad(liquor)?
  • if developed nation sells weapon how can it be a member in peace process?In what way they are promoting peace?
  • if medicine is to cure 1 disease how is it that it has 5-10 side effects is that called curing?
  • How can one be a good parent if he/she were bad kid?
  • Can a drunkard advice a teetotaler about controlling desire and temptation?
  • Why should one comply with a goal which is in the opposite direction of the one that have been conceived and without even knowing what one implies?
  • How can a kid grow up in a chaotic and unharmonious environment(exception are there)?
  • Why do people's thinking so shallow?
  • Don't people have the ability to recognize all by themselves that they are good or bad or hypocrites or bourgeois?
  • Isn't it wrong to demand from others what one cannot implement on oneself.
  • Why don't people think for intellectual progress instead of material progress?
  • Is ignorance letting us be human or animal?
  • Isn't the system wrong if one has to fight for anything?
  • how can one quantify the intellectual progress?
  • when love happens only one time then how is that lovers marry a different partner?
  • why people who worked for money instruct those who work for the type of work rather than money.

UI of DT 845W

Subject in discussion: Binatone DT 845W wireless ADSL2+ Modem router

Its web interface doesn't show which all machines are currently accessing the Internet unlike wa3002g4 which gives the machines accessing (mac address as well as ip address). The reason for checking out was to implement a time limit for Internet access for a particular machine based on mac address.
wireless mac address, ACL, filter type, parental control filtering option are given.

Freedom compromised due to **ignorance**

Its high time that computer users indulge in basic updation of their own knowledge regardless of age factor, the main reason behind such an advice/request is because of the unnecessary trend that gives the user the impression that one has to  keep up the up-gradation of semiconductors even when the need is very basic. But for a user to know what is basic and what is not he/she should know what he will be working with.
The incident that happened is real and I could not feel much better after i insisted on my recommendation on a very basic stuff like IDE over SATA.
This was really not very technical in nature but the need of one of the users(ignorant of course, no disrespect meant) device be replaced and unfortunately the service guy who insisted on SATA than IDE even with the SATA drive not being recognized by BIOS, so used other(IDE) drive to install (you know what == Msoft) and from with in in order to make the SATA drive available to the OS had to install raid driver and made it work(kudos to him, no doubt) but when insisted on IDE drive he came up with an argument that in case of upgrading the system one can use the SATA drive hence saving penny but when I asked him what if the same problem of install the os comes, the drive is useless if its not recognized by BIOS. Apart from that even in the OS one has to install the raid now why complicate the matter when IDE is available. He won't budge , isn't it compromising our freedom to install what ever we want whenever we want, one has to depend on him for that.  If the user is not interested in upgrading the sytem then what?
Why is it that a normal demand like IDE is preferred over SATA creating so much of fuss?
Aren't users responsible to chose what they want? for this to happen users need to grow beyond clicking on start button and taking application of their own choice and thats their own responsibility to upgrade knowledge and no one will spoon feed them or take class on such matters.
