  • Best inkjet color printer for CAD document?

    I've got a HP 1180c inkjet color printer which I used to print CAD document and worked fine with minor troubles for the past 10 years.

    Now I think it's time to replace it and get a new printer.

    I would like to know which printers are suitable for replacing my printer considering quality of output, price and value, reliability and maintainability.

    The requirement is simple, the printer must be able to print on A3 papersize, relative fast paper per minute, good color output quality, non-complicated driver and software.

    Thanks.

  • Cara mengetahui bagian pipa yang bocor?

    Saya ada masalah dengan pompa air di rumah. Pompa tsb ada di lantai 2 dan digunakan utk menyedot air dari bak penampung di lantai dasar.

    Beberapa waktu lalu, pompa harus dipancing air dulu setiap kali dinyalakan. Tapi sekarang pompa air tidak bisa menarik air lagi walaupun sudah dipancing.

    Dari tanya - tanya dan browsing, dapat info kalo harus dicek check valve ( tusen klep ) dan kebocoran pipa hisapnya.

    Memeriksa atau ganti check valve bisa saya lakukan sendiri, masalahnya kalo ternyata yang bermasalah adalah pipa hisap.

    Bagaimana cara mengetahui bagian yang bocor pada pipa hisap? Karena kalau harus dibongkar dan ganti baru lebih repot buat saya.

    Makasih.

  • something is calling isc.org from inside my computers on network....?

    For few days I've been surprised by a huge amount of connection request from within my network to one of ISC address on port 80.

    The address is 204.152.184.139

    All requests are block by my firewall.

    I've been searching through the net to find some more info regarding this issue.

    I'm suspecting something nasty is going on, since there is no alert from our antivirus system ( trendmicro officescan )

    I tried to use well-known antimalwares and antispywares programs on a sample computer but found nothing suspicious.

    netstat -anb shows :

    TCP 172.16.3.232:4021 204.152.184.139:80 SYN_SENT 1444

    c:\windows\system32\WS2_32.dll

    C:\WINDOWS\system32\WININET.dll

    -- unknown component(s) --

    [svchost.exe]

    Any idea what I'm dealing with??

  • how to stop facebook from sending notification emails?

    This is kinda new case for me.

    A colleague has been receiving notification emails from facebook to her email address that never ever used to register on facebook.

    The email address is company related and she's smart enough not to use it to anything silly on the internet.

    Facebook started sending her notification emails after somebody tagged her in a photo on facebook.

    Which is, kinda wierd.

    I tried to check whether her email ever been used to register facebook account by trying to recover password with her email address as reference.

    But we got a page telling us that the email address has never been used to register an account.

    So, in short, I've got this situation :

    - An email address that never been used to register a facebook account

    - Facebook has been sending notification emails to this email address.

    - This happen after somebody tag a photo. As the notification emails say "A-Person-Name has tagged a photo of you"

    Which makes me wonder how can it be possible.... :(

    Thank you
