How to install Ubuntu 14.04 Wifi on Lenovo Thinkpad E145 ?
Even though E145 already listed on Ubuntu 14.04 supported OS but still the Wifi was not working unless we install the E145 wifi broadcom’s driver manually.
One way to install the driver is through Ubuntu GUI interface with following steps:
1. Make sure internet connection through Ethernet / UTP cable.
2. Click on “System Settings” and then “Software & Updates”.
3. On the folder of “Ubuntu Software” checked “Community-maintained …”, “Proprietary drivers …”, “Software restricted …”, and unchecked “Cdrom with …”.
4. Click on “Additional Drivers” folder and checked on “Using Broadcom 802.11 Linux …”. See below picture as reference.

Mengapa sebagian kanal nexmedia tidak bisa diterima ? Kejadian ini telah dialami dan cukup membingungkan, walau pada akhirnya ditemukan solusinya tetapi jawaban teknisnya masih kurang memuaskan.
Dari beberapa sumber bahwa ternyata Nexmedia, persisnya mesti dicek lebih jauh, menggunakan teknologi DVB-T (Digital Video Broadcasting – Terrestrial) MPEG4 64QAM pada band VHF untuk DVB-T dengan kisaran frekuensi 290 – 328 MHz. Perkiraan kanal Nexmedia sebagai berikut:
Kanal A: 290 MHz ; Kanal B: 313 MHz ; Kanal C: 320 MHz
Pada frekuensi tersebut antenna dan splitter yang umum di pasaran seharusnya bisa digunakan karena bisa bekerja untuk VHF maupun UHF.
Tetapi pengalaman saya agak aneh karena dengan penggunaan antenna splitter rangkaian standar menyebabkan kanal B Nexmedia tidak jalan (Power dan Quality sinyal hanya 2%) sedangkan kanal A dan C cukup baik dengan Quality > 40%. Sebagai catatan untuk mendapatkan sinyal Nexmedia yang baik di daerah Tangerang arahkan antenna ke arah Cipondoh.
Setelah buntu dan penasaran utak-atik, akhirnya dicoba dengan cara rangkaian tidak standar yakni kabel untuk receiver Nexmedia dilangsungkan ke antenna (tidak melalui splitter lagi), yang juga dipararel dengan splitter yang mana keluarannya tetap seperti semula untuk tv kedua. Dengan cara seperti ini kanal A, B dan C pada Nexmedia jadi bagus semua, demikian juga tv kedua bagus hasilnya. Jadinya seperti pada gambar berikut ini …
Jangan pakai antenna splitter untuk Nexmedia
What is 3 in 1 in Jakarta?
Jakarta’s local government was struggling to reduce traffic jam, especially on busy hours. One of the regulation enforced since 2003 was “3 in 1″ (“three in one”) for car usage within city’s main street. “Three in One” or “3 in 1″ means that only car with at least 3 passengers allow to enter a road. Exceptions are for public transportation, including taxi. It is kind of little things of traffic engineering which trying to reduce numbers of private car usage.
The idea is to reduce car usage which only used by 1 or 2 persons, and enforce people to use car effectively. At beginning this regulation was works, but after a while there were many “joki” (kind of jockey) tricks. Joki is person that offer their service to accompany the car driver to fulfill minimum 3 passengers in a car, of course with some fee (money). They usually waiting next to the street which 3 in 1 regulation is applied. Even though security officers did routine patrol, the Jokis still available almost everyday … just like cat and mouse.
The “3 in 1″ regulation only applied during busy hours, which are:
– 07.00 a.m. until 10.00 a.m. in the morning, and
– 16.30 p.m. until 19.00 p.m. in the evening
Regulation applied along Sisingamangaraja St — Sudirman St — Moh. Thamrin St, and Gatot Subroto St. Refer to the below map (see red color dotted) which detailed on https://www.google.com/maps/@-6.2013943,106.8055198,13z

Official car parking fee in Jakarta city of Indonesia much cheaper compare to other world’s big cities such as Tokyo, Los Angeles, Berlin, Singapore, etc. Even though it is quite expensive for ordinary locals in Jakarta.
As for instance in 2014, parking fee for first hour was 2,000 – 5,000 Rupiahs (equal to 20 – 50 cents USD), and for next hourly was 2,000 – 4,000 Rupiahs per hour (equal to 20 – 40 cents USD). While unofficial parking fee could be about 2,000 – 5,000 Rupiahs for many hours, unofficial means temporary parking lot which handle and arrange by a person without any receipt nor timer which are many in Jakarta. If compare to Tokyo parking fee which up to 500 yen per hour (equal to 4.5 USD), this fee is so cheap !
Parking Receipt in Jakarta
Currently Jakarta’s traffic was very bad, traffic jam were almost allover the city. In the morning I took at least 2 hours from home to office which is about 18 kms distance, at evening almost the same when go back from office to home. Local government in Jakarta was struggling to built Mass Rapid Transportation, hopefully it can be happen within 3 years time. Otherwise Jakarta’s traffic jam would be very very bad. Even though the traffic condition but people prefer to use own car or motorbike because of public transportation availability, quality and its security issues.
Higher parking fee regulation in other hand could be used by local government to push people to use public transportation, but only if its already in good condition.
