The Legend of Koizumi, Volume 15, “Senkaku Islands Bloody Battle”

tron keyboard anime cover 52785
TRON keyboard on Japan comics book cover. The Legend of Koizumi, Volume 15, “Senkaku Islands Bloody Battle”. by Hideki Oohwada, Kindai Mahjong Comics. (ムダヅモ無き改革 15 (近代麻雀コミックス) | 大和田 秀樹 )
《小泉麻將傳說》第15集, “血战钓鱼岛”.

Mudazumo Naki Kaikaku (ムダヅモ無き改革 Reform with No Wasted Draws, also known in English by its initial subtitle The Legend of Koizumi) is a satirical mahjong manga by Hideki Ohwada.

It was initially irregularly serialized in the Kindai Mahjong Original manga magazine published by Takeshobo, then switched to bimonthly serialization on Takeshobo's other mahjong manga magazine Kindai Mahjong in April 2009.

The premise of the manga is that international diplomacy is settled on the mahjong table, with real-life politicians depicted as masters of mahjong.

The Japanese title is a parody of Junichiro Koizumi's slogan, “Reform with No Sanctuary” (聖域無き改革 Seiiki Naki Kaikaku).

《小泉麻將傳說》(日語:ムダヅモ無き改革,英语:The Legend of Koizumi,即小泉傳奇),是日本漫畫家大和田秀樹的麻將漫畫,從2006年起不定期連載於竹書房《近代麻雀original》上,在2009年4月起改至《近代麻雀》上連載。

note that in older trackballs, they use a roller for the ball contact. (with mechanical optical sensor) Most of today's trackball e.g. logitech, use a solid material as ball contact points. Arguably, less smooth, more friction.

Elecom HUGE Trackball (added a video)

this one, came out last year (2017) with much fanfare, but is it good?

i've seen both praises and nah comments. Some find this to be the ultimate trackball. While others, finding the shape is really not optimal for their hands.

i've seen simliar remarks on • Kensington Expert Slimblade • L-Trac • Elecom EX-G.

with trackballs, you really have to see for yourself which is best, for you.

Star Wars BB-8 Droid

Star Wars bb-8 droid toy. interesting mechanism. but the bot is rather idiotic. Sphero Star Wars bb8

in real life, such bot can only be used indoors. Even so, it has lots problems. Gets dirty, head prone to fall off, can only work on smooth level surface, and agility is 0, nimbleness is 0.

the way it works is: imagine a heavy square, 10 cm long but 1 cm thick, sitting at bottom of the ball. The corners are mouse wheels. In middle is a pole, at top of pole is a magnet. The pole can be pivoted.

there are 2 different makers of the bb8 toy. This one, sphero bb8, is better. Sphero Star Wars bb8

how i love happy hacking

oh yeah, i love happy hacking. it makes me happy, and hacking, and all cool kids in town married one.

on the first day of xmas i love its F1 key. On the 2nd day of xmas i love its F2 key. On the 12th day i love its F12. On the 13th Friday i love its virtual arrows. I can finally live my life in virtual Doom.

when friends come over, they envy my expensive brick. All the chicks wanna touch it. I can't even fight their dirty hands off.

i used to pride in thinking, but the hhkb made me unthink fast by bouncing on rubber domes. Colleagues can't even tell with my fingers all over in production.

highly recommend: once you get this you'll forget about touch typing and never pain again

I credit @xah_lee with opening my eyes to the importance of spacebar size and modifier key placement. (It did ruin some otherwise great keyboards for me, e.g., Sun Type-5.) @XBowstech seems to have some original ideas here that also feel like they would be genuinely useful.
