was playing around with some iPad’s styli lately and here they’re: the Wacom Bamboo stylus, TruGlide, Adonit Jot, Adonit Jot Touch, Jaja, Cregle’s iPen and ByZero. I’ve been loving the smoothness of Bamboo, but TruGlide is really an excellent one! The new Adonit Jot Touch seems to be promissing, and on the second position is Jaja (for pressure sensitive styli).
t would start within a week from now, the well – expected event of Apple’s world – wide developers conference of 2012 – WWDC 2012. To welcome the tech fair 😛😛, on the left is a screen capture of what I’ve been working hard on for the whole last month (the video is not really clear since it’s shot with my phone), a photo browser UI like iPad’s Photos app. It takes time to learn insights into Core Graphics, Core Animation, and I’m still learning. For all those years of graphics I’ve been through, Apple UI and its graphics sysem are still sooo… brilliant and amazing to me! (and “our love has just begun”!) Keep heading North!
gày nào, cho tôi biết, biết yêu em rồi, tôi biết tương tư, sau đây là câu chuyện tình tôi tự kể,
ngày nào, biết mong chờ, biết rộn rã buồn vui đợi em dưới mưa… Chúng tôi quen nhau tính về thời gian chưa phải là quá lâu, chỉ một vài năm gì đó. Nhưng nguồn cơn, nguyên do câu chuyện có lẽ đã được vun vén, manh nha từ lâu rất lâu về trước, tôi thương em dễ có
từ thủa mẹ về với cha.
Những lý do, ngọn nguồn chẳng thể nào mà giải thích và truy nguyên cho được đã dần đưa chúng tôi lại với nhau tự lúc nào. Tình yêu nào rồi cũng sẽ đi qua nhiều thăng trầm, đã có lúc tôi cảm giác chẳng hiểu gì về em, nhiều khi sự khó khăn của em làm tôi nản chí, cũng có khi tôi đã hoang mang, nghi ngờ em và chính mình.
Nhưng với tình cảm chân thành, bằng trực giác tự nhiên mách bảo, chúng tôi đã vượt qua nhiều sóng gió, để đến một ngày:
ngày nào, cảnh thiên đường, đã mở hé tình yêu là trái táo thơm, tôi ghé răng cắn vào… Đến đây thì hẳn các bạn đã đoán ra nàng thơ của tôi tên là… Apple – hiện diện trên các MacBook, iPhone, iPod, iPad xinh xắn! 😬
his is just a post of my truly nonsense and random thought. Some notions are just interesting in their own forms, like writing on the margins or sub luna saltamus – dance beneath the moon… I just particularly like the phrase
writing on the margins, the action and its meaning, that’s why this website layout is designed with that notion in mind, the left column is reserved for additional and complementary information, as side notes along main content.
Take a look at the two iPad’s screenshots on the left and you would see how nice it is, writing on the margins in a modern and digital form, especially when you could still use your own handwriting with it. You may have noticed the two classical masterpieces (one in mathematics and the other in literature) referenced in those notes! 😀
ust got the new iPad (or we called it: the iPad 3) in hand today and I’m stunned by it’s new retina display. There’s not such a fever like when the iPad 2 was released, I guess since the new iPad is almost identical to iPad 2 in appearance, people will consider about the fact that they won’t be able to show it off. In term of general performance, iPad 3 does not stand out to the previous iPad, or it could be worse in term of 3D – OpenGL performance according to some reviews. From a programmer’s point of view, this could easily be understood since doubling the resolution means 4 times the memory and processing power for each graphics API, which also means Apple has been pushing things over the Moore law’s limit!
Personally I’m not really a passionate fan of these Mắc – Xinh – Tốt ⓵ (Macintosh) assets, but professionally as a computer – graphics coder, I’ve always admired the prestigous 2D graphics tradition come with Apple’s products. Back to the retina display, on the left is a reduced – size screenshot of this blog taken on the iPad 3 (see full version here, it would take some times to load).
2048 x 1536 is a huge resolution that does magic to the vector things, e.g: displaying fonts! Not only the screen is much sharper, even at first look, its color tone appears to be truer, and the new iPad gamut covers 44% more into the sRGB color space compared to the previous iPad. The second picture: funny capture of Walter Isaacson’s Steve Jobs autobiography put on – top the God of Wealth’s altar in our office 😀!
⓵⏎Mắc – Xinh – Tốt: a phonetical transcription of the name: Macintosh, which is a play–on–words, Mắc means: expensive, Xinh means: cute and Tốt means: good in Vietnamese 😀.
uch an interesting device I’ve used recently, a stylus for iPad. While stylus like Wacom’s Bamboo is fine for general sketching, it’s not really suitable for fine – grained drawing. This Byzero takes a different approach as it does not use iPad’s touches, but provides its own mechanism. Image on the left: you can see that the pen is actually an ultra sound source, two microphones (and an infrared receiver) in a single piece plugged into the iPad connector port. Pen position detection is done by triangulation on the acoustic signals. This kind of setup can be found on many other things like this 3D laser scanner.
If you use the iPad seriously for taking notes and drawing, a stylus like this is a must, sometimes your thoughts, ideas can only be expressed with a pen: text, drawing and all kinds of presentations on a page. The stylus is sensitive, it can captures any glyphs you draw. However, it’s very irritating that the calibration process is not really exact: pen position is offset – ed by a small varying distance, and with a noticeable delay… This reduces the usability of the stylus much since it’s important to have immediate and correct responses on the screen for user to make micro – adjustments in his hand to produce good writing, drawing.
