Handphone LG GW 300

Handphone LG GW 300
Handphone LG GW 300

Handphone ini dibeli sekitar tahun 2009. Paket pembeliannya sudah termasuk protektor karet warna hitam. Pada waktu itu (2009) kemampuannya sudah cukup lumayan. Pada tahun 2014 ini saya rasakan kelemahannya:

  • Relatif lambat dibandingkan handphone baru
  • Proses menghapus SMS terasa lambat, padahal memory SMS cuma dapat menampung sekitar 400.

Kelebihan yang masih terasa:

  • Hemat batere, dapat tahan beberapa hari standby, dibandingkan dengan smartphone canggih seperti Samsung Galaxy S4 yang tiap hari baterenya minta dicharge.

Untuk penggunaan menelepon dan SMS, handphone ini masih cukup enak.

Card Reader Mumuksu MCR-381

Update 14 November 2015: Card reader Mumuksu MCR-381 akhirnya rusak, seperti dibahas di artikel http://kabarkita.org/2015/11/14/card-reader-mumuksu-mcr-390/

Banyak notebook saat ini sudah dilengkapi dengan SD card reader, sehingga kita tidak perlu lagi membeli SD card reader. Namun jika kita menggunakan Compact Flash memory card maka kita perlu menggunakan card reader khusus. Dari pengalaman menggunakan berbagai card reader, ternyata banyak yang abal-abal, hanya berfungsi sebentar terus mati, atau tidak kompatibel dengan card tertentu. Dari sekian banyak card reader yang saya coba, salah satu yang bertahan adalah Mumuksu MCR 381. Cukup cepat, kompatibel dengan USB 3.0 dan tidak rewel.

Perbandingan ISIS/IS dan Al Qaeda

Bendera ISIS
Bendera ISIS
Bendera Al Qaeda
Bendera Al Qaeda

Berikut ini adalah perbedaan antara ISIS (Islamic State of Iraq & Syria) /Islamic State dan Al Qaeda.

  1. ISIS, Al-Qaeda and the Arab revolutions: Al Qaeda memilih menumbangkan pemerintahan dengan bekerjasama dengan kelompok-kelompok lain, baru kemudian mendirikan negara Islam. ISIS langsung mendirikan negara, meskipun dengan menuduh kelompok-kelompok lain sebagai sesat.
  2. Accusing opponents and the general community of apostasy: ISIS aktif menuduh lawan-lawannya dan masyarakat umum sebagai sesat.
  3. Fighting the enemy that is near first: Al Qaeda beroperasi di seluruh dunia, ISIS hanya aktif di daerah Irak , Syria dan sekitarnya saja.
  4. The strategy of sectarian mobilization against antagonists: ISIS aktif menyerang kelompok-kelompok syi’ah.
  5. Severing links to Iran by divorcing itself from Al-Qaeda: Al Qaeda masih ada hubungan dengan Iran. ISIS tidak ada hubungan resmi dengan Iran. Malah sempat terjadi kontak senjata antara ISIS dengan Iran di Qasre Shirin.
  6. A different and brutal media strategy: Pemimpin Al Qaeda sering muncul di media massa. Pemimpin ISIS jarang muncul. ISIS lebih menekankan berita-berita mengenai aksi di lapangan.
  7. An immoral, tougher and more extreme Salafist Jihadism: pandangan ISIS lebih ekstrim dibandingkan Al Qaeda.

Sumber: http://english.alarabiya.net/en/perspective/alarabiya-studies/2014/06/19/Who-leads-global-Jihad-al-Qaeda-or-ISIS-.html

The Islamic State of Iraq and Syria (ISIS) is moving according to strategies and perspectives of a state lying amid violent hotbeds and safe havens. It creeps into structures of unsuccessful regimes while flourishing during their periods of turmoil.

This is why ISIS believes it is capable of leading global jihad, unlike Al-Qaeda which focuses on the distant enemy rather than the enemy that is near. Al-Qaeda’s central leadership has weakened and is incapable of supporting its affiliates.

This is what qualifies ISIS, with its constant expansion and successes in chaotic contexts on the national, regional and international levels, to take over Al-Qaeda and the leadership of global jihad.

We can identify features that distinguish Al-Qaeda from ISIS such as the former’s apparent lack of moral principles, unlike Al-Qaeda, as well as its operational focus on expanding on the geographical level to establish an interconnected state described as the “ISIS crescent.”

This sought-after state extends from historical Diyarbakir (southeast Turkey) and includes Raqqah (north central Syria), Mosul and Nineveh (both in Iraq) among others.

Leading figures in ISIS also rarely make media appearance, unlike their counterparts in Al-Qaeda.

The two entities can be distinguished in terms of the following seven points:

1- ISIS, Al-Qaeda and the Arab revolutions

ISIS did not wait to get involved in the Syrian revolution and almost immediately began accusing parties on the ground of being apostates, mainly the Free Syrian Army, in a practice known as takfir.

The group believes that the FSA is more evil than the Syrian regime and the Sahawat and launched an offensive against the Syrian opposition group, killing many of its activists. Nor did ISIS confront the Damascus regime, choosing instead to focus on fighting revolutionary factions in regions it controlled.

This stands in contrast to the stances taken by Al-Qaeda’s leadership which welcomed the revolutions aimed at toppling longstanding regimes in the region.

This general view was expressed by the founder of Al-Qaeda, Osama Bin Laden, before his death on May 2, 2011. The same stance was expressed by Aiman Al-Zawahiri, Bin Laden’s successor, who in 2011 issued an address to Egyptians titled a “Message of hope and glad tidings for our people in Egypt.” The late Anwar Al-Awlaki issued a similar stance in his message about the Yemeni revolution. The Libyan revolution was viewed in a similar manner by the late Atiyatallah Al-Libi. This view was repeated in Abdullah Al-Adam’s booklet titled “Revolution of the Peoples: Is It the End of the Protested Kings?” in which al-Adam expressed his desire to wait until the triumph of the revolution before intervening to support the establishment of an Islamic state.

 

ISIS is well known for accusing different armies, opponents and general communities – not just rulers – of apostasy, particularly those who do not seek recourse to Sharia as a rule and reference.

In his message to Al-Zawahiri on May 12, ISIS spokesman Abu Mohammad al-Adnani blamed Bin Laden’s successor and Al-Qaeda, saying:

“We invite you secondly to correct your doctrines; declare openly the apostasy of the Egyptian, Pakistani, Afghani, Tunisian, Libyan and Yemeni armies and all the other armies of tyrants and their supporters; not manipulate legitimate commands and expressions as you have done in your descriptions of “corrupt rule,” “void constitution” and “pro-American army”; issue a frank call to fight the Egyptian army of [Abdel Fattah] Al-Sisi – the new Pharaoh of Egypt; disassociate from [Mohammad] Mursi and his party as well as openly declare his apostasy and stop causing misconceptions among Muslims.”

Al-Adnani also refuted Al-Zawahiri’s description of Egypt’s ousted president Mursi as being a victim.

ISIS also criticized jihadists belonging to the Nusra Front and their leader, Muhammad Al-Jawlani, who affirmed his allegiance to Al-Zawahiri.

ISIS labeled Al-Jawlani a traitor and insisted on its war against him and maintaining the group’s stance regarding the Sahawat and other factions involved in the Syrian revolution, namely the FSA.

3- Fighting the enemy that is near first

Unlike Al-Qaeda and Al-Zarqawy (1966-2006), ISIS prefers to fight the enemy that near to it, focusing on regions where it is present, and prioritizes the expansion of its influence over offering guidance and forging a spiritual connection among jihadists around the world.

The latter was a goal of Al-Qaeda and its central leadership which have become isolated from their supporters on the Pakistani and Afghan borders ever since Sept. 11, 2011.

Al-Qaeda is in distress after the loss of its most prominent and influential leaders in recent years such as its founder, Bin Laden, and Al-Libi in 2011, Mustafa Abu al-Yazid in 2008 and many others.

The suicide operations by ISIS are conducted exclusively in Iraq and Syria. The group has not conducted sting operations against the West or the United States, in line with ISIS’ conception of itself as a state and not an organization like the Taliban.

4- The strategy of sectarian mobilization against antagonists

Unlike Al-Qaeda, Al-Zarqawi and ISIS have attacked Shiite rallies. Their organizations have published studies that support labeling all Shiites as apostates.

Al-Zarqawi has released several videos in which he stresses the righteousness of his practices.
He also condemns his critics, mainly Abu Muhammad Al-Maqdisi.

As noted by Fatih Karikar, Al-Zarqawi’s strategy was to work on the sectarian mobilization of Sunnis against the Shiite rise after the fall of Saddam Hussein. He saw it as an opportunity to form a Sunni army in order to achieve the goal of establishing or restoring the Caliphate and the Islamic state.

This is what ISIS is apparently doing in Iraq, supported by the speeches and practices of Nouri Al-Maliki and Bashar al-Assad.

5- Severing links to Iran by divorcing itself from Al-Qaeda

Al-Qaeda never attacked Iran, nor did it support any Sunni organization targeting the Iranian regime. ISIS was similarly committed and complicit in this arrangement until it broke off from Al-Qaeda and ultimately Iran. Al-Adnani expressed this in his message when he said that the organization abided by these guidelines “in compliance with Al-Qaeda’s order to preserve its interests and supply lines in Iran.”

Apparently, this contradiction reveals the pragmatism of both organizations and their undeclared connection with Iran, which served as a safe haven to many of their leaders after 2011, as per Saif Al-Adel’s analysis of Al-Zarqawi’s statement, which revealed the true identity of Yassin al-Suri, known as “Al-Qaeda’s fox.” In December 2011, the U.S. administration said Al-Suri had been moving freely in Iran between 2005 and 2011.

6- A different and brutal media strategy

ISIS may have benefited from Al-Zarqawi death, which was likely linked to his repeated appearances. This explains why ISIS leaders chose not to make appearances, as opposed to Al-Qaeda’s leaders.

ISIS media focuses on its operations on the ground and facts, avoiding theoretical and intellectual debates with the group’s opponents.

In contrast, Ayman al-Zawahiri, the present leader of Al-Qaeda, has made frequent appearances, whether in the open meetings where he has answered questions or fatwas from his opponents or the series of “peoples’ messages” dedicated to the Egyptians among others.

ISIS media messages are limited. The group focuses on the military and operational side as part of a fear campaign aimed at its opponents. Their media tactics are similar to those of Al-Zarqawi in terms of the level of violence in the messages. In 2004, Al-Zarqawi posted a video in which he is seen beheading U.S. civilian Nicholas Berg. The video was shocking and terrifying and was highly criticized back then, even from Al-Qaeda’s leaders and strategists. This is what ISIS is doing now.

7- An immoral, tougher and more extreme Salafist Jihadism:

ISIS has no ethics and it seems to rely on the ideological beliefs of extreme Salafist Jihadism, unlike many of Al-Qaeda’s on-ground commanders such as Abdullah Azzam, Al-Zawahiri, Al-Libi, Al-Ayiri, Al-Tuwayli and others whose views were known from their writings. Other Al-Qaeda theorists included Muhammad Al-Maqdisi, Abi-Qatada Al-Filistini and Abdul Qader bin Abdul Aziz.

But it seems that ISIS has adopted the firmness of Salafists without referring to Al-Zawahiri’s ideology, nor debated views of fellow jihadists who criticize it and are against it. ISIS is an organization with the perception of a state. Its battles are tangible and not theoretical: it carries out direct confrontations, unlike Al-Zawahiri, who entered indirect confrontations with his critics.

ISIS shares Al-Zarqawi’s vision. He was not the most educated or cultivated among leaders of the jihadists’ Shura Council which he established in 2005, but he was always present on the field and enjoyed the strongest of organizational skills.

Perbandingan kecepatan memory CF Sandisk Ultra II dan V-Gen

Latar Belakang

Artikel berikut ini dibuat pada tahun 2010.

Berikut ini adalah perbandingan kartu memori Compact Flash Sandisk Ultra II 2 GB dan V-Gen 4 GB. Sandisk adalah salah satu merek memori yang cukup terkenal, sedangkan V-Gen adalah merek memori lokal Indonesia.

Pada waktu tulisan ini dibuat, harga card memori CF kurang lebih adalah sebagai berikut:

  • CF Sandisk Ultra II Rp 200.000,-
  • CF Sandisk Extreme III Rp 300.000,-
  • CF V-Gen Rp 165.000,-
300-sandisk-ultra-ii-IMG_4562
Compact Flash Sandisk Ultra II
300-vgen-4gb-IMG_4559
Compact Flash V-Gen

 

Metode Pengujian

Metode pengujian adalah sebagai berikut:

  • Card Compact Flash dimasukkan ke kamera Canon EOS 50D, kemudian diformat.
  • Kamera 50D diset untuk kecepatan frame maksimum (sekitar 6 frame per detik).
  • Ukuran gambar yang dihasilkan diset ke RAW, ukurannya sekitar 18 Megabyte per gambar.
  • Tombol shutter ditekan dan ditahan selama kurang lebih 1 menit. Pada sekitar 14 foto pertama, kamera menaruh gambar di memori lokal kamera, sehingga kecepatan pengambilan gambar maksimum. Setelah itu memori kamera penuh, dan kamera baru bisa mengambil gambar lagi setelah gambar yang di memori kamera dipindahkan ke memori CF.
  • Percobaan ini diulangi untuk CF yang satunya.

Tabel hasil pengukuran dapat dilihat pada lampiran artikel ini.

Setelah pengambilan gambar selesai, dibuat tabel waktu terhadap jumlah gambar yang diambil. Kemudian tabel itu dibuat grafiknya. Grafik tersebut dapat dilihat pada gambar berikut:

grafik-perbandingan-sandisk-vgen.preview

 

Pada gambar tersebut terlihat bahwa pada sekitar 14 foto pertama, kecepatan sangat tinggi, sesuai dengan kecepatan shutter kamera. Namun setelah itu kecepatan pengambilan gambar akan dibatasi oleh kecepatan transfer gambar dari memori kamera ke memori CF. Terlihat bahwa kurva untuk Sandisk lebih curam daripada kurva untuk V-Gen, artinya CF Sandisk Ultra II lebih cepat daripada CF V-Gen.

Untuk mendapatkan kecepatan transfer memori, saya perhatikan saja waktu yang diperlukan untuk mengirimkan gambar ke 20 sampai dengan gambar ke-40. Pada memori CF Sandisk, untuk mengirim gambar 20 sampai 40 diperlukan waktu 33 detik, sedangkan pada V-Gen untuk mengirim gambar 20 sampai 40 diperlukan waktu 62 detik.

Kesimpulan

  • CF Sandisk Ultra II 2GBmampu mengirim 20 foto @18 mega dalam waktu 33 detik
  • CF V-Gen 4GB mampu menulis 20 foto @18 mega dalam waktu 62 detik
  • Ada harga ada rupa 🙂

Berikut bom serupa produksi Amerika: Mk 81, Mk82, Mk83 dan Mk84

Bom keluarga Mk 80 an
Bom keluarga Mk 80 an

Dari pengamatan sekilas, bom tersebut adalah Mk 84 dengan berat peledak 2000 lbs , sekitar 1000 kg. Sirip di belakangnya nampaknya copot ketika bom tersebut jatuh.

Seberapakah daya hancur bom tersebut? Berikut ini kutipan dari wikipedia:

The Mark 84 is capable of forming a crater 50 feet (15.2 m) wide and 36 ft (11.0 m) deep. It can penetrate up to 15 inches (381.0 mm) of metal or 11 ft (3.4 m) of concrete, depending on the height from which it is dropped, and causes lethal fragmentation to a radius of 400 yards (365.8 m).

Mark 84 dapat membuat kawah selebar 15,2 meter dan sedalam 11 meter. Bom ini dapat menembus besi setebal 381 mm atau beton setebal 3,4 meter, tergantung dari ketinggian dijatuhkannya, dan dapat melontarkan kepingan mematikan sampai jarak 365,8 meter.

Kalau bom seperti ini diledakkan di tengah kawasan padat penduduk , tentunya banyak yang jadi korban. Selain itu bom ini juga tidak dilengkapi sirip pengendali, sehingga ketepatannya tergantung bidikan dari pilot ketika melepaskan bom ini.

Bom Mk 84 ini harga per buahnya adalah USD 3100, sekitar Rp 34 juta. Relatif murah dibandingkan dengan bom berpanduan seperti GBU-10, namun ketepatannya rendah. Bom tipe GBU dilengkapi pengendali dan pengarah laser sehingga ketepatannya lebih tinggi.

Berikut ini video ledakan bom Mk 84. Bom yang dipakai di video itu adalah laser guided, bukan free-fall.
