Mengakses komputer dari ruang rapat dengan VNC

Seandainya kita sedang di ruang rapat dan perlu mengakses Desktop kita karena komputer ruang rapat enggunakan Win$ dan kita bekerja dengan Linux, ada 2 protokol yang bisa digunakan untuk itu.

Pertama dengan RDP. Ini protokol yang sebenarnya punya M$. Di Linux, ada server xrdp, dan di Win$ dipasang clientnya. Aplikasinya, saya nggak explore. Yang saya kerjakan dulu menggunakan Win2003 server sebagai RDP server dan rdp client di Linux. Tapi saya kira yg third party juga banyak. Tapi jangan tanya soal Lisensi, ya. Lebih pusing mikirin lisensi ketimbang menggunakan protokolnya. Belum lagi, 5 CAL user yang awalnya dijanjikan, tiba-tiba mati setelah trial 2 bulan.

Kedua, ini yang asik, menggunakan VNC. Di Linux bisa juga menggunakan protokol frame buffer (RFB), kalau di KDE tinggal:

$ sudo apt-get install krfb

(boleh juga dengan
$ sudo apt-get install tightvncserver)

Panggil krfb (alt+f2, ketik krfb atau click di system tray pojok kanan bawah). Create personal invitation, catat passwordnya.

Di Win$, kita pasang VNC viewer (client) dari (misalnya) TightVNC dari GlavSoft. Panggil tightVNC viewer, isikan IP kita, misalnya 192.168.1.101.

Balik ke Desktop, accept connection.

Balik ke Ruang rapat, isikan password.

Kalau monitor Desktop tidak dimatikan, maka icon mouse dan aplikasinya bisa 'ngetik sendiri'. Kalau nggak suka, buka saja xwindow baru untuk menutupi 'hantu' ini. Biar nggak heboh!

Best lightweight browser

Links2 text based browser running on graphic mode

Sometimes, even with EVDO connection promised to be 3.1 MBPS, connection can be slower than CDMA1x. A normal EVDO can averagely be 80 kbps download in most place. It should be more than 300 kbps, but I never find the right spot. Maybe inside the provider's office, very near to the tower antenna, but outside, with so many customers and weaker signal, information can be so much expensive.

Bagaimana menyiasati internet lambat tapi tetap bisa menikmati informasi lewat browser? Ya dengan browser yang hanya mengambil bagian terbesar informasi yang kata Alquran dalam bentuk tertulis (teks). Di dunia Linux, ini teknologi lama yang terus dijaga dan dikembangkan. Diantara browser yang didesain untuk keperluan ini adalah elinks, links2, lynx, netrik, w3m, wikipedia2text (dengan kerjasama dengan salah satu text browser sebelumnya), dan ... (nggak perlu diceritakan lagi, yaitu) (x)emacs.

elinks, links2, lynx, netrik, w3m hampir sama. Mereka adalah platform yang sempurna untuk text browsing termasuk untuk digunakan bersama wikipedia2text. w3m mempunyai fitur table/frame sehingga webpage nyaris mirip aslinya kecuali semuanya berupa teks. netrik mempunyai rencana fitur lebih banyak lagi.

Sedikit lebih boros dan keluar dari terminal adalah links2. Links2 mempunyai versi grafis yang mampu menampilkan gambar jpeg. Untuk membaca gmail yang kaya Javascript, kita bisa masuk ke modul html-nya gmail. Maka sebagian buesar informasi di email akan terbaca.

Kalau tidak bisa hidup melulu dengan teks, uzbl dan dillo benar-benar hidup diluar terminal. Berbeda dengan browser biasa, keduanya ringan karena cita-citanya memang hanya mengambil informasi dasar sebuah web page.

Diantara browser modern, Midori cukup cepat, tapi dengan kemampuan java script, cookies, flash, dll ya ... sudah keluar dari konsep awal untuk hanya mendownload informasi utama yang berupa teks, kalau nambah ya sedikit style seperti tabel atau frame..

Googleearth 6 in Debian Squeeze

1. $ sudo apt-get update
2. $ sudo apt-get dist-upgrade
3. Download deb package from http://earth.google.com
4. $ sudo dpkg -i go*.deb
5. If many dependency failures, this is the last working try: $ sudo apt-get install lsb-core lsb-release pax alien rpm rpm2cpio libelf1 librpm1 librpmbuild1 librpmio1 libelf1 librpm1 librpmio1 rpm-common

Hint: I did block (double click in the package) and middle click (anywhere in terminal) to get the dependency transferred at the cursor position.

Hisab Ramadhan 1432H

Ringkasnya, pada 30 Juli, saat matahari terbenam, kira2 bulan ada di -5 derajat. Pada hari berikutnya, bulan ada di posisi +6 derajat di atas ufuk. Jadi insya Allah kita mulai puasa bersama tanpa beda pendapat.

Mudah-mudahan bermanfaat.

sun-java di Lucid

Gara2nya mau masang freemind. Karena butuh sun-java, maka mesti masang openjdk-6-jre. Karena di Lucid require tzdata/2010m-0ubuntu0.10.04, maka download dulu paket tersebut di
https://launchpad.net/ubuntu/+source/tzdata/2010m-0ubuntu0.10.04/+buildjob/1995244
Lalu, simpen di /var/cache/apt/archives/
Kalu enggak, ya langsung install saja agar menimpah paket defaultnya.
Mungkin developernya perlu diberi tahu bahwa dependensi paketnya ada yang mogok?
Ok, deh. Aku juga register di launchpad ...

plone collective.geo.contentlocations

1. edit buildout.cfg
2. run buildout
3. got this error: "No such file or directory: '/home/enviromatics/Plone/zinstance/parts/instance/etc/zope.conf'"
4. means zope.conf has been deleted due to unclean product install (http://plone.293351.n2.nabble.com/Restart-Zope-td5151549.html); well the product got lots of dependency.

errors:

1. warning: no files found matching '*.mo' under directory 'collective'
2. warning: no files found matching '*.js' under directory 'collective'
3. warning: no files found matching '*.mo' under directory 'collective'
4. the rest seems rooted on them

resolution:

1. clean collectives from buildout.cfg, rerun buildout to get the site back
2. start with the errors now ... ::debugging mode on::

g3data - extract data from graph

1. Point to x0, x1
2. Put value on x0 and x1
3. do the same on y axis
4. Point of n1..nn values
5. export data in dat
6. import dat file using spreadsheet, customize the position

create new graph/trend.

short review: kbibtex enak!

Saya search artikel buat nulis tentang one-dimensional modeling untuk banjir
jakarta di search.ebscohost.com.

Tanpa babibu di web ebscohost yang lumayan lemot, saya save aja hasil
pencariannya ke format bibtex. Hasilnya dibuka di kbibtex, baru diverifikasi
mana yang perlu dan download fulltextnya.

Ebscohost memang sudah mengandung folder saya pribadi, tapi karena aksesnya
aras2en ya ... lebih mantep dibrowse dengan kbibtex.

Selamat mencoba!

Project management

Review ringkas versi desktop:
1. Planner sudah terbiasa tapi miskin fitur, Gnome.
2. Openproj, java, kaya fitur tapi tidak terintegrasi dengan desktop (misalnya address nggak bisa impor dari KDEPIM)
3. KPlato menjanjikan karena bagian dari Koffice, tapi belum matang benar, meski lebih kaya dibanding planner
4. OpenOffice Project management, ditunggu tapi belum lahir aja ...
5. Task Juggler sepertinya kaya fitur dan mestinya terintegrasi dengan KDE tapi UInya belum ada.
Web based, mestinya baik buat team work tapi belum punya kebutuhan

Web based:
Tadinya mau pakai egroupware karena ada di Debian dan dapat award. Tapi fiturnya terlalu kaya?
Kalau untuk Plone, ada 3: PoI, extreme.projectmanagement dan task progress atau apa udah terlanjur ditutup tabsnya... Nyarinya dari Download > Project Management + 3 + task. Produk ke 2 yang mau digunakan.

Menulis buku: tools

Sepertinya word prosesor, yang banyak fitur seperti MS Word dan OpenOffice.org terlalu gemuk untuk penulisan buku. Selulit dari kedua contoh word prosesor tersebut membuat distraction penulisan, karena penulis seharusnya lebih konsen ke konten bukan tampilan dengan Heading, footnote, styles, dst.

Persis iklan TeX dan turunannya macem LaTeX, Lyx, dst.: konsentrasi ke konten, karena tampilan sudah diurus sama TeX.

Kalau nggak ada TeX mungkin cukup gedit, kate dan freemind. Atau openoffice.org draw, tapi bukan inkscape dan gimp karena akan jadi distraction baru.

Setoran ke penerbit cukup dengan rtf dan gambar dalam 1 folder. Atau pdf hasil editan TeX kalau nggak mau repot ngasih judul gambar dengan nama file.

Linux inside windows

For the sake of untarring and make-ing OpenCaster, I tried cygwin inside my winvista box since connection via atheros on eth0 af my acer timeling 3810tg doesn't resolved to work.
But after a while of trying and checking colinux, I think the best resolution for using Linux inside win box is Virtual Machine.
And it's worth with the 4GB of RAM in Acer Timeline.
Thank you!

Plone 3 and GIS

Sepertinya ada banyak pendekatan.

• primagis - 0.6 is not designed for plone 2 (http://lautaportti.wordpress.com/2007/02/12/primagis-in-plone-30/)
  
• zgeo.wfs - issued 27 oct 08. Debian Lenny is with plone 3.1.3 which is released on 10 July 08. Should be fine.
