Zebra F-301 ballpoint pen hack

Without further due, here is a hack replacing the Zebra F-301 F refill with the one from Uni-ball Jetstream 0.5mm. Get the smaller Jetstream refill, usually the one to refill the Uni-ball multipen.

See that the Uni-ball Jetstream refill is the same length as the Zebra F refill.

The next step is to open the black cap from the F refill. This is easily done using your nail. Then you’ll have to take out the refill from inside the barrel. This also can be done by hand, just push down-up.

Push the inside, from the tip towards the upper end.

Here is the F refill and its barrel.

Next, you’ll have to do a hack to put the Jetstream refill into the F refill barrel. You can use your creativity. What I did was cutting a bit of the black cap from the F refill, and some part of the Jetstream plastic (same length), and then wrapped the middle with some tape, to keep its position in the barrel.

You have to sacrifice the black cap here. However you can do other hack, limited only by your creativity.

Now put them altogether into the F-301 body, and Voila! This is better and cheaper than my Parker.

The best pen (gel) I have used so far.

An Idea: How Can Linux Win More Users?

I am a full time working engineer. In my spare time, I like to try new things, including Linux. It took me more than 4 years to fully using Linux on my computer, on and off. There are several reasons: (1) Installing Linux and making all hardware work took much time, which I don’t have, (2) I can’t find a truly powerful MS Excel® alternative in Linux. That’s true up to now.

For reason number (1), it is not true these days, at least with certain distros. I bought a cheap ($200) used Thinkpad® X100E and replace the OS with Crunchbang Linux “Waldorf”.

Unfortunately, for reason number (2), it is still true. We have to admit that in this world, there are many MS Excel® power users, consultant, developers, and add-ins. They solve problems, create businesses, and produce value. It is powerful because there are so many stakeholders and business created over MS Excel®.

I use LibreOffice-Calc (version 4.1.5), as it is native in Linux. In my experience, it is still sluggish compared to MS Excel®, e.g. when I press-and-hold my arrow key to move between cells, the screen refresh is not as smooth as in MS Excel®. This is true especially with out-of-the-box configuration.

Up to now, in my short period learning to use Calc, one of the advantage is its Solver, which has more decision variables limit (in MS Excel®, you have to pay an add-in to get same capability).

A good OS is one thing. A good spreadsheet with many power users, business tool, plug-ins, are as important, if not more.

Microsoft® will not port MS Excel® to Linux, because they know, it is one of the softwares that keep its users from migrating. As for me, I’m trying to live with Calc as long as I can.

[Series] Tips for Learning

I’d like to start a series of learning tips. I hope this is useful for you and for me as reminder. So here is the first tips.

Declaring or put a goal like (for example) I’d like to learn programming, is often and most likely useless. One should accomplish something to effectively learn. The result may not be perfect but in the process, we learn. In the example of learning to program, one can set a goal to accomplish a simple software written in the program that she/he wants to learn.

In my case, I set to learn to use a numerical porous media simulator. I have installed the software, download the manuals. But I cannot make progress since I didn’t set a goal to accomplish something.

See you in the next tips.

Careers for INTP Personality Types

Whether you’re a young adult trying to find your place in the world, or a not-so-young adult trying to find out if you’re moving along the right path, it’s important to understand yourself and the personality traits which will impact your likeliness to succeed or fail at various careers. It’s equally important to understand what is really important to you. When armed with an understanding of your strengths and weaknesses, and an awareness of what you truly value, you are in an excellent position to pick a career which you will find rewarding. INTPs generally have the following traits:

  • Love theory and abstract ideas
  • Truth Seekers – they want to understand things by analyzing underlying principles and structures
  • Value knowledge and competence above all else
  • Have very high standards for performance, which they apply to themselves
  • Independent and original, possibly eccentric
  • Work best alone, and value autonomy
  • Have no desire to lead or follow
  • Dislike mundane detail
  • Not particularly interested in the practical application of their work
  • Creative and insightful
  • Future-oriented
  • Usually brilliant and ingenius
  • Trust their own insights and opinions above others
  • Live primarily inside their own minds, and may appear to be detached and uninvolved with other people

INTPs have a special gift with generating and analyzing theories and possibilities to prove or disprove them. They have a great deal of insight and are creative thinkers, which allows them to quickly grasp complex abstract thoughts. They also have exceptional logical and rational reasoning skills, which allows them to thoroughly analyze theories to discover the Truth about them. Since the INTP is driven to seek clarity in the world, we have a happy match of desire and ability in this personality type. INTPs will be happiest in careers which allow them a great deal of autonomy in which they can work primarily alone on developing and analyzing complex theories and abstractions, with the goal of their work being the discovery of a truth, rather than the discovery of a practical application.

The following list of professions is built on our impressions of careers which would be especially suitable for an INTP. It is meant to be a starting place, rather than an exhaustive list. There are no guarantees that any or all of the careers listed here would be appropriate for you, or that your best career match is among those listed.

Possible Career Paths for the INTP:

Scientists – especially Physics, Chemistry
Photographers
Strategic Planners
Mathematicians
University Professors
Computer Programmers or Systems Analysts
Technical Writers
Engineers
Lawyers / Attorneys
Judges
Forensic Research
Forestry and Park Rangers

Disiplin VS Hukuman

“Hukuman!” Dibayangkan saja sudah menyeramkan, seolah-olah hukuman itu identik dengan penjara, dipukuli, dikucilkan, dipermalukan, ataupun direndahkan.
Bagi yang terbiasa memberi ‘hukuman’ kepada anaknya akan terasa tidak begitu penting dari sebuah nama tindakan yg diambilnya. Di negara-negara maju, tindakan ‘hukuman’ baik berbentuk fisik maupun emosional berurusan langsung dengan pemerintah dan dinas sosial negara. Akan tetapi saya percaya jika anda sudah mau membaca tulisan saya kali ini, anda adalah orang yang bijaksana, yang mau berubah demi kebaikan anda, anak-anak anda, bahkan keluarga anda. Maka dari itu saya mengajak semua orang tua, guru, carers, semua orang yang terlibat dalam usaha mendidik dan membesarkan anak, untuk mengubah pola pikir kita. Konsekuensi sebuah tindakan yang tak diharapkan tidaklah harus berupa sebuah ‘hukuman’. Jauhkan kiranya kata-kata itu dari hati dan pikiran kita, apalagi kita berbicara soal anak-anak kita sendiri, anak didik, anak asuh, anak bangsa.

Mulailah tanamkan pada pikiran kita bahwa: ‘seorang anak yang berperilaku tidak sesuai dengan harapan kita sebenarnya membutuhkan KEDISIPLINAN’. Saya percaya anda semua setuju dengan saya dalam hal ini. Kenapa beresiko memberi hukuman kalau bisa disiplin, kan!?!

Pada kesempatan yang akan datang, saya akan berusaha menuliskan secara singkat beberapa tindakan disiplin yang mudah dilakukan namun jitu pada hasilnya, jauh lebih jitu dari pada memberikan hukuman. Percayalah Papa dan Mama, Ibu&Bapak Guru, Nanny, dan carers.

Untuk kesempatan kali ini, saya akan bagikan sedikit beberapa hal yang efektif membantu persiapan kita mendisiplin anak. Yaitu:
1. Pastikan jadual rutinitas stabil, seimbang (belajar, bermain sendiri, bermain bersama, berdoa, aktifitas di luar rumah, aktifitas di dalam). Anak mencontoh kedisiplinan orang tua lho!
2. Buatlah daftar perilaku yang diharapkan. Komunikasikan hal tersebut dengan anak anda agar dia mengerti jelas apa harapan anda. Pakailah bantuan gambar agar mudah diingat dan di’baca’. Daftar Perilaku ini bisa diubah, ditambah atau dikurangi sesuai situasi dan tingkat kedisiplinan anak anda.
3. Buatlah daftar perilaku yang tidak diharapkan. Ringkaslah daftar itu menjadi -/+ 3 sampai 5 kategori besar, maksudnya agar anak tidak menjadi bingung dan kebanyakan aturan yang membuatnya frustrasi. Komunikasikan dengan singkat, jelas dan relax kepada anak.
4. Kumpulkan semua mainan kesukaan (10-20 items) dalam satu kontainer sedang. Hiasi kontainer tersebut agar anak merasa menjadi bagian penting dalam kepemilikan barang-barang tersebut. Buatlah persetujuan bahwa setiap barang mainan yang berasal dari kontainer tersebut harus kembali saat selesai bermain. Daftarkan persetujuan ini di Daftar Perilaku yang diharapkan seperti yang dijelaskan di poin ke-2.
5. Buatlah persetujuan konsekuensi / sebab-akibat:
a. Jika perilaku yang diharapkan dilakukan, maka anda bisa membuat strategi ‘penghargaan’ yang akan memotivasi anak untuk melakukan tindakan yang diharapkan tersebut. (Saya tidak akan menjelaskan hal ini, karena saya bukan pendukung sejati ‘Reward System’, akan tetapi anda bisa mencarinya di internet dan konsultasikan dengan therapist, sekolah, atau psikolog kenalan anda.
b. Jika perilaku yang TIDAK diharapkan dilanggar, maka haruslah diambil tindakan disiplin. Hal disiplin inilah yang akan saya jelaskan lebih detil dikesempatan selanjutnya.

I’m here because of you.

Hi again everybody, let’s compete that from this day on, our children will be the luckiest happiest proudest kids ever lived on earth.
Competition eh?! It’s an encouraging one though. So, is the challenge accepted!?! :0)
I’ve heard many youth say, “I never asked to be born!” with a usual sarcasm and so on. You know, I will never want to hear my future kids say those words that way.
All I can do now is hope for the best and have faith in God that when I raise my children, my main purpose is to assist them find their own purpose in God.
So one day they’ll come to me and say, “My privillege to serve the Lord our God with you. I’m so proud to be a part of His glorious works. Love you Mom n Dad.”

Wait, don’t answer yet!

Some 3-5 year olds do ask oodles of questions, and parents do answer so quickly to satisfy everyone or show the kids that they know everything. Quick answers are also delivered to quickly get rid of all interruptions so to reach a peace of mind. But is that what really happens when you give quick answers to your kids? I bet my bottom penny you don’t usually reach that peace at all. The quicker you answer, the more questions asked. Because that’s just what kids do. “Why? Ohh…. Really? But why? But why? Why???” Sometimes I even wonder if they really want to know why or just another powerful attention seeking method they naturally invented and passed on from one generation to another. However, in my opinion, both are worth attending to.
So instead of spending some time with your kids by quickly answering questions, please do spend some quality time with them by doing some adventurous investigation together. This is not a new thing to discuss anyway. Every parent from the school I used to work at, knew exactly the theory of not answering questions instantly. Although some of them just couldn’t help it but uncovered the facts in express mode. I remember some parents came to me frustrated, “Now I don’t know how to answer their questions anymore, why is ‘someone’ pregnant?”
There are books, internet resources, pictures, models, museums, other people, places eg. Hospitals, etc, that can help parents equip their kids with some research skills. Those skills are going to be very much needed as they get older. Invest your time, creativity, and a little extra energy no matter how fed up you are with life other than home. There will be more questions they’d ask in life, but you won’t be there with the answers forever.
Your kids should know how to fight for what they believe in, so you’d better guide their beliefs in the right direction.

God bless you.
