Smartcard Training Using Smartcafe

OK, now I'm away from Xen or any virtualization. I have a training starting from monday in Hotel Binakarsa. The training is about smartcard and held by Finnet Indonesia (a child from Telkom). We are kindly managed by Mr. Martin. He's a nice person, I kinda like him (not in term of J*s20 or J**b20).

The first two and a half day, we're playing the bottom knowledge of smartcard. Programming it up! The smartcard we are using is G&D's (a german company). It's based on Java Smartcard and GP 2.1.1 (or 2.2.1?). Still, we learned OP 2.0.1' (OP 2.0.1 enhanced by VISA).

The software we use is SmartCafe 3.0 SP2. It's quite delicated to use the software. We must provide a dongel otherwise we cannot use it! Man, the last time I'm dealing with dongel software is with Surpac and it has a software dongel (other word, bajakens.... ssst.. gw gak pernah coba itu software... asli loh... asli beneran...). Anyway, the limited dongel ... bla.. bla... -_-' This is quite way off the topic.

Ok, back to the topic. Sorry...

We are concentrated at GP 2.1.1, but Mr Edward (our trainer) also mentioned about OP 2.0.1.
I'm confused with the command. But, the bottomline is, the instruction is so Compiler Lecture-like. It just about how to give certain hex and interprete it as data or command.

The data we use is short and byte. Array is supported but use one dimensional only! Avoid use too many data. Space is the common constrain here. Somehow in my mind, we must think like the game developer in the early 80's to 90's.

The smartcard we have from G&D is somehow limited by 64 Ks. It support the standard but it only have real DES encryption capable. The AES, PKI, and other encryption stuff is only a fake function (they always return true or the same value). Well, DES is quite capable and enable to do a lot of stuff.

The apps is called an applet (don't confuse with the web's). It has this code transformation:

Java source code --> Java Bytecode --> Card Application (CAP).

A CAP file is actually a JAR version of Smartcard.

Doh, I'm getting bored here. I wish to introduce the applet structure.. Ow, alright.

The applet is a class that override the Applet class. Again, don't be confused with the Web one. Ah, I'm already tired. Sorry... next other time.

Btw, the accomodation is fine. We stay at Bumikarsa Hotel. Yeah, just like a standard hotel, have a nice warm shower, nice swimming pool, nice lobby with Internet, and a nice eating room where we can pick various food from Western to Indonesian. But, it has a lack of accomodation that important: No server to play with! ;( Man, I miss the oprek-oprek. Plus, they don't have LINUX!!! X-(

At morning and day we have breakfeast from the eating room. In the night, we are eating outside. Yesterday, we eat at a Sunda Restaurant near the hotel. This night, we go to the Plaza Indonesia. We eat at the foodcourt after that we take a little hike and go drink in Tator.

Btw, you know what our conversation? Yeah, the typical of CS people. We talk alot about Smartcard and the implementation. Mr. Edward is a very nice people type. He has his thinking and we spent a lot of time by sharing his knowledge and our plan in using the smartcard.

Ow, ok, I know when we eat we should take a rest and have a recreation. But, what is the recreation? PI is only filled with women stuff. I don't see any interest in seeing beautiful women with her nipple shown. What is the good to see an artist? I hate Sinetron and hate it so much because of the poor script and bad personalization. So, to me PI is kinda boring. No computer stuff, I even can't find InfoLINUX there....

The only amusing is when we saw the screen. It has an Award BIOS, indicating that it was only a PC... and I try to imagine if I can touch the keyboard.

It's already late and I just want to sleep now. Bye.

STAN vs. UI

Ugh, kasihan banget adek gue. Saking kepinteran dia jadi dapet Akuntansi UI dan STAN. Jadi bingung mau masuk yang mana. Beberapa orang (termasuk orang tua gue), menyarankan masuk STAN. Gue malah memperburuk suasana dengan membela memasuki Akuntansi UI, maklum bela almamater. Duh, gue jadi merasa bersalah bikin dia ragu-ragu. Kira-kira enakan masuk mana, yah? Gue juga gak tahu keuntungan masing-masing. Hasil debat sementara: ~ Untuk jangka panjang masuk UI, untuk jangka pendek STAN. ~~Tapi, dia itu kan cewek, ntar pas menikah kemungkinan besar karir terhambat. Eits, ntar, dulu, sekarang kan jamannya emansipasi, bisa aja cowoknya yang jadi BRT. ~ STAN sarang korupsi, kalo masuk STAN jadi pegawai negeri. Kalo mau kaya harus korupsi. Tapi kalo masuk UI, lulus masuk jadi akuntan publik. Sekarang ini, orang membayar akuntan publik untuk memanipulasi nilai pajak dan aset. *SIGH*. Jadi gak ada yang beres ~ dll. Yah, udah gue jadi bingung, apa lagi dia nanya saran gue. Buah, gue gak pengalaman ...

Installing Goodix Fingerprint Reader Driver on Fedora

I currently have a Lenovo Thinkpad L14 laptop equipped with fingerprint. I was `belok` from KDE Neon to use Fedora 40 because of someone. Now I am tempted to enable my fingerprint: lsusb | grep -i fingerprint Bus 001 Device 004: ID 27c6:55b4 Shenzhen Goodix Technology Co.,Ltd. Fingerprint Reader Dump the firmware Assuming this is a fresh install, lets do some magic by getting some dependencies: sudo dnf install gcc git python-pip python-devel openssl Let's get the source code: git clone --recurse-submodules https://github.com/goodix-fp-linux-dev/goodix-fp-dump.git cd goodix-fp-dump Create an isolated Python environment: python -m venv .v source .v/bin/activate Do the magic: sudo su pip install -r requirements.txt python run_55b4.py exit There are some python scripts available. I run run_55b4.py because my device ID is 27c6: 55b4 . It will spell some nonsense, which is a good thing. That nonsense actually the firmware captured by our device. Also, I typed exit becaus...

Chivalry vs Feminism

Throughout these years I constantly making experiment about how our society perceive about the societal changes. The overhaul of sexist strata and the privilege reformations follow. Note that every change could be perceived as progress or detrimental to the society. The foremost subject that I run is about the opposite of manliness perceived by the oldies vs modern women. The modern era allow women go out from the kitchen into the office. They can have career and enjoy the privilege that men were exclusively had in years. And, can men also do the reverse? Can men also enjoy the privilege of what women do in the past? Can men move from office into the kitchen? And the answer on this era is: NO. While women could reverse their role, men are not allowed to do the same in this society. Society will punish you when a man tries to do that. They will put a healthy man who chose to be at home dad as an irresponsible not-a-man person. If a woman's worth could be rewritten, why not...
