エッシャー展

こないだ、ちょっと渋谷で時間が空いたのでスーパーエッシャー展を見てきた。期待通り、面白かった。1時間もいなかったから、堪能って訳には行かなかったけど、ちょっといい時間。
陳列の最初のほうにある初期の「身近なもの」と分類された作品も、ちょっと異常なほど几帳面。昔のパタリロ!の絵みたい。(あ、当然影響なんでしょうが)
42 「地獄」はボッスの絵「快楽の園」より「木男」というものをコピーしたらしいけど。

変な生物がエスカレートしてて面白い。
46 図式化されたJ.S.バッハの平均律 – CGで動きを加えたものが展示されてた。なるほど!
「ゲーデル、エッシャー、バッハ」を思い出した。動きがあって理解度がぐーんと上がった気がする。しかしまた読み返すのはなかなか勇気がいるなあと思いつつ、Amazonでみてみたら、20周年記念という版が出てるのね。
ゲーデル、エッシャー、バッハ―あるいは不思議の環 20周年記念版

「本当は何を書いた本なのか?」多くの読者を悩ませ楽しませてきた問いに、ついに著者自ら答える序文収録。

って言われたら、そこだけでも読みたいじゃん…
63 アトラニ – 海岸の館の風景、メタモルフオーゼに使われている、って書いてあったけど、メタモルフォーゼのところで見るの忘れた。
中年になって正則分割に懲りだす、アルハンブラ、イスラムのモザイク。
92 昼と夜 – 初めて正則分割の応用作品という事で大きく取り上げられ、人もたかってる、でもあまり面白くない。
97 エッシャーノートの展示 – 几帳面なのが良く分かる、正則分割の、モチーフの場所と組み合わせ方の規則がびっしり書き込まれている。
125 バールン高校のタイル貼柱 – こんなのが学校にあったらずっと見入っていそう。
144 物見の塔 – この頃になってだまし絵がでてくる。60才。
165 ペンなどが入った道具箱 – Ritmeester Wilde Havanaと書いてある。葉巻のハコですな。
158 Mott the Hoopleのジャケット。そういえば見たことがある。エッシャーだったのね。

160 レコード・ジャケット Puzzle / Mandrake Memorial
– でんぐりでんぐりのパレードがすごい。知らないバンドだけど。

レーザー通信の実験はゴルフボールを狙うようなもの?

欧州宇宙機関(ESA)が、飛行中の飛行機間のレーザー通信リレーを行うことに成功した。
Hitting a golf ball with a laser at 33,000 feet – Network World
2万5千マイル(4万km)離れたところにいる、高度2万から3万3千フィート(10km)の飛行機間の通信を静止衛星が中継。
それは、素晴らしい、って話でいいんだけど。
例えとして、「パリとブリュッセルの間を飛んでいるゴルフボールに当てたようなもの」って言われてもなあ。
かえってよく分からん。
しかしこれ、通信以外の目的もあるんだろうなあ。

PDAでプレゼン

たかがプレゼンするためにPCをもちあるくのが嫌だ。
という訳でPDAでプレゼンする方法が欲しい。
一声2万円かあ。
ほんとにこれ、うまくいくのかなあ。
とりあえずI-Oのは、とっくに生産終了している模様。

Using A PDA To Deliver A PowerPoint Presentation
Margi Systems creates the Presenter-to-Go (US$199) series of cabling devices that connect your Palm or a PocketPC based PDA to a projector. Margi’s product includes a complete line for both the Palm and the PocketPC – these usually attach to PDAs using the CompactFlash, SD Card or Memory Stick slots on the PDA themselves. The other end of Margi’s cabling devices feature a VGA out port that plug straight into a projector. Margi’s offerings include an IR remote that controls the presentation along with a PowerPoint compatible software that needs to be installed on both your Windows based system and the PDA. Margi also includes a Margi printer-driver that converts output from any Windows application to a Margi compatible file – much like the Adobe PDF printer driver.
Colorgraphic with its Voyager VGA CF card (US$175) based cabling device is another major player in the market. Unlike Margi, the Voyager offering works only with CompactFlash cards on your PDA – so if your PDA lacks a Compact Flash card slot, you won’t be able to use this product. On the other hand, Voyager’s product allows you to connect your PDA to a computer monitor and television as well apart from a projector. Voyager includes the ClearVue Suite from Westtek, a bundle of PDA applications that can show unaltered files from PowerPoint, Word and Excel.
I-O Data creates CFXGA that is a CompactFlash type display-out interface card (US$175) – this is again bundled with Westtek’s ClearVue Suite and can interface to projectors, televisions and monitors. Beyond the Palm and PocketPC platforms, I-O Data’s offering is unique in that it supports Sharp’s Linux based Zaurus PDAs as well.

NWが勧める展示会。
CESがComdexの代わりとして紹介されてる。Tom Hanks and Morgan Freeman なんて人たちも、来るのね。
Linux Worldが入ってるのも、面白い。
Mark your calendars: trade shows worth your time in 2007 – Network World
Consumer Electronics Show (CES), Las Vegas, Jan. 8 ? 11
CES is the new Comdex, with attendee estimates as high as 140,000 for the 2007 event. But despite its size, many show veterans say if you want to take the pulse of the industry, CES is where to do it. With 1.7 million square feet of expo space the event is giant ? no doubt you’ll leave feeling you’ve missed something ? but offers a great view of the intersection of the PC and entertainment industries; keynote speakers for next year’s event include Bill Gates and Michael Dell as well as the presidents of Walt Disney and CBS.
As for the show’s focus, you may need to pass by dozens of consumer gizmos before coming across something you would actually allocate budget for. At first blush enterprise IT types [http://www.networkworld.com/columnists/2006/010906cooltools.html] might brush off all that gadgetry as irrelevant, but as one Network World staffer puts it: “If you’re an enterprise IT professional who doesn’t get into the little stuff you see at CES, your boss called ? he’s shutting down the branch offices and wants the sales reps to work from home. OK if they pick out their own SOHO IT gear, expense it and have you support it?”
Plus there’s the celebrity citings: Justin Timberlake, Dana Carvey, Tom Hanks and Morgan Freeman all appeared in 2006, to name a few.
RSA Conference, San Francisco, Feb. 6 ? 9
Going on its 16th year, the RSA Conference bills itself as the world’s largest community of information security professionals. Conference tracks delve deep into security technology, with 2007’s event covering aspects such as authentication and developing with security. However, despite the technical depth of the content, it’s easy to get lost in the noise of this conference with the “increasingly Mardi Gras-like parade of vendors, speeches, presentations and other events that may overwhelm the attendee,” says one Network World reporter.
Any vendor that’s remotely serious about security will be on hand. Oracle CEO Larry Ellison will take the stage for the first time at this event, as well as perennial keynote speakers Bill Gates and, of course, the head of RSA Security, now owned by EMC. The theme for the 2007 conference is “celebrating the influence of 15th-century Renaissance man Leon Battista Alberti, who created the polyalphabetic cipher,” according to the Web site. Perhaps more interesting will be the vendor-sponsored Texas hold `em contest.
IBM’s SHARE User Events, Tampa, Fla., Feb. 11 ? 16 and San Diego, Aug. 12 – 17
User events can be tricky; they need to be technical enough to get some serious questions answered, but broad enough to still be interesting. Past attendees say the quality of the technical sessions at SHARE User Events is high and the access to IBM engineers and executives is impressive. Perhaps that’s because the event is organized by SHARE, which is an independent, volunteer-run IBM user association.
The event, which began as a gathering of mainframe users and has been going on for more than 50 years, bills itself as a place where IBM users can influence future product direction and glimpse new technology from Big Blue and its partners. It’s a biannual event; one season’s show isn’t necessarily bigger or better than the other. There also are some wacky antics ? as you may expect would happen at any show that’s been running for 51 years straight ? such as sing-alongs and Button Man sightings.
LinuxWorld OpenSolutions Summit, New York, Feb. 14 ? 15
This new event, aimed at corporate IT professionals, is designed to reflect Linux’s move into the mainstream. The agenda is heavy on technical sessions and case studies, and stresses attendees learning from each other, instead of being shouted at by vendors.
LinuxWorld OpenSolutions Summit grew out of the LinuxWorld conference to better focus on corporate deployment of open systems in verticals ? the February show will cater to financial services, healthcare, pharmaceutical, retail, media and the public sector. Topics to be covered include security, network management and interoperability, applications and best practices, virtualization, desktop, and legal issues.
(This event is organized by IDG World Expo, a sister company to Network World.)
VoiceCon, Orlando, March 5 ? 8
Billing itself as the place to “build your IP telephony platform,” VoiceCon has been around for 16 years and has a concentrated audience with roughly 5,000 attending the 2006 spring event. The content also is focused, as evidenced by the speaker lineup that includes top brass from Avaya, Cisco and Nortel. Sessions will touch on technical issues such as IP-PBX system security as well as business concerns such as the organizational impact of migrating to converged networks.
Our reporters say this event has more enterprise appeal than VON and better content and speakers than Internet Telephony. The spring version of this show will be the one to attend in 2007.
CTIA Wireless, Orlando, March 27 – 29
Run by CTIA ? the Wireless Association (which used to stand for the Cellular Telecommunications Industry Association, but the group is looking to widen its focus), this event covers the spectrum of wireless developments, but its bread and butter continues to be cell phones. Still, there are some enterprise issues on the event’s 2007 schedule, such as day-long programs dedicated to VoIP mobility and wireless data.
The spring event is the one to attend; CTIA’s fall event, called CTIA Wireless IT and Entertainment, ends up being more about the latter than the former, attendees say.
But there’s still an element of hipness at the spring show ? the event features a mobile fashion show of wearable electronics, and among the industry luminaries scheduled to speak are entertainment kingpins Sean “P. Diddy” Combs and Russell Simmons.
Gartner Symposium/IT Expo, San Francisco, April 22 – 26
This conference covers a wide range of technologies, business issues and management strategies, but with the benefit of the Gartner analysts’ filters; all attendees have the opportunity to meet face-to-face with as many as three Gartner analysts during the event. The speaker lineup for 2007 isn’t out yet, but this year’s event attracted the likes of Microsoft CEO Steve Ballmer and Cisco CEO John Chambers, both of whom took the stage to be grilled by Gartner analysts. And the analysts do the bulk of the presenting at the event, corralling most of the vendors to the expo floor.
The event is small and expensive; 2006’s show had 6,000 attendees, and early bird registration for the 2007 conference is $3,495. However, in addition to access to Gartner analysts, the event offers attendees access to each other. “The way the show is laid out … everybody eats breakfast and lunch together in a huge tent. This provides a great way for people to network,” says one Network World editor.
The event is open to all IT professionals, not just Gartner clients.
Web 2.0 Expo, San Francisco, April 15 ? 18
This new show grew out of the Web 2.0 Conference, which has become an invitation-only event focused on next-generation Internet technologies. It is supposed to focus on the practical application of Web 2.0 principles, and will feature an expo floor as well as technical sessions and tutorials.
Skipping the big ideas behind Web 2.0 in favor of finding out how to make these technologies work sounds like a wise way to spend your travel budget.
Storage Decisions, Chicago, May 5 ? 7
This highly focused event ? the one in September attracted 500 storage managers ? aims to interest both storage specialists as well as IT executives by covering technical and business issues related to storage. With such a small number of attendees, the event bills itself as a great place to network with “true peers.”
Little information is available about the May 2007 event, as the Web site focuses on the pending December show, which has as a theme scaling storage while managing costs. The speaker list for these shows is heavy on analysts and consultants, with some vendors and users mixed in.
Interop, Las Vegas, May 20 -25
Billing itself as the meeting place for the IP infrastructure market for the past 20 years, the spring version of Interop really can’t be missed, unlike its fall counterpart, which in 2007 will be in New York and has become something of a snoozer. Not only do the show organizers arrange programs by technology ? next spring’s show promises to cover application networks, data center, infrastructure, network security, VoIP and collaboration, and wireless and mobility ? but there are also boot camps tailored to specific titles such as CIO or CSO.
As expected the show took a hit in attendance following the dot-com bust and its effect on the networking industry, as well as the tightening of IT budgets that ensued. But Interop Spring 2006 saw a bit of a renaissance in interest and buzz, attracting around 18,000 attendees, according to conference organizers. Next year’s event promises more of the same.
NXTComm, Chicago, June 18 ? 21
This new show is the melding of two existing events, GlobalComm (which grew out of Supercomm) and TelecomNext. Put on by a pair of associations, the Telecom Industry Association and the United States Telecom Association, this is another event billed as the place where the IT and entertainment industries converge ? albeit with more of a telecom slant.
Not much is known about the event ? the organizers haven’t even officially decided on a show logo yet ? but predictions put the number of attendees at 22,000. Because it will fill the void left by the closing of two other shows, it’s likely to become the defacto must-attend telecom show. Hopes are that the event will regain much of the value and buzz that Supercomm enjoyed in its heyday.
Alternates
If travel schedules or other inconveniences keep you from the shows listed above, consider some of these events:
InfoSec World, Orlando, March 19 ? 21
If you can’t make it to the RSA Conference, InfoSec is a good alternative. A bit quieter than the RSA Conference, InfoSec also focuses on all things security and in 2007 will offer sessions on a range of topics including risk management, identity theft and endpoint security, to mention a few. There also will be a few one-day summits that drill down on specific topics, such as compliance, and a special track for CISOs. Plus, who would want to miss William Shatner’s keynote address entitled “A trek from science fiction to science fact.”?
Voice on the Network (VON), Boston, Oct. 29 ? Nov. 1
Celebrating its 10th anniversary this year with roughly 10,000 attendees at the fall event, VON’s focus encompasses IP communication in the enterprise and the development of Internet-based entertainment. Speakers at this year’s fall event ran the gamut from Ted Leonsis, vice chairman of AOL, who talked about the company’s expanding video services, to enterprise types such as a network engineer at Liberty Mutual who stressed the importance of VoIP security. Next year’s fall event will cover VoIP-related topics as diverse as fixed mobile convergence and IPTV.
Storage Networking World, San Diego, April 16 ? 19
Organized jointly by Network World sister publication Computerworld and the Storage Networking Industry Association (SNIA), this relatively young event enters its ninth year in 2007. The event promises to highlight storage trends while featuring
user case studies and offering hands-on tutorials from SNIA.

5カ月の乳児、人間の顔認識

こんな事を、一生懸命研究してんのか。
asahi.com:5カ月の乳児、人間の顔認識 生理学研究所が発表 愛知?-?社会

 体内に赤外線を投射して酸素の消費量を測定することで、脳の部分的な活性化を調べるNIRSという装置を使用。首がすわって視力が安定した、5~7カ月の乳児10人の頭に装着し、正面から見た人間の顔、上下を逆にした顔、野菜の画像を見せ、脳内24カ所の酸素消費量を測定した。
 その結果、顔の認知に重要な役割を果たすとされる脳の右半球で、正面の顔を見せた際の酸素消費量が、逆向きの顔や野菜の画像を見せた場合の約3倍になり、脳が活性化していることが判明。

わざわざそんな事調べんでも、ウチの6ヶ月の娘はしばらく前から人の顔見てわらっとるよ。
