ただただし氏が数十年後、「自然エネルギーに騙された」と言わないために - ただのにっき(2011-04-08)で科学的懐疑心の重要性をとき、本旨の導入として斉藤和義の「ずっと嘘だった」とその態度への批判をしている。
ただ氏の批判を抜粋する。
断っておくけど、おれは別に原発推進派でもなければ反対派でもない、強いていえば消極的容認派だけれど、だからといって今さら「絶対安全って言ってたのに! 騙してたなんてひどい!」なんて騒がないよ。世の中に「絶対」なんてものがありえないって知ってるし。悪いけど、「絶対安全です」なんて言われて信じるほうがおかしい。
こんな歌、十代の子供なら許されるかも知れないけど、斉藤和義はもう44歳、おれと同世代じゃないか。この歳になったら言っていいのは「(自分より若い世代に対して)無知でごめんなさい、騙されててごめんなさい、黙っててごめんなさい」だろうよ。いい大人がイノセンスぶって責任回避かよ、情けねぇ。
さて、ただ氏の言うように斉藤は今回の事故をキッカケに、これまでの「絶対安全」が嘘だったことに気づき、「ずっと嘘だった」を歌った情けない大人なのだろうか。
「ずっと嘘だった」の歌詞には「原発が５４基」「ほうれん草食いてえな」というフレーズがある。
これは忌野清志郎が1988年に発売したカバーズに収録された曲「ラヴ・ミー・テンダー」と「サマータイム・ブルース」を意識していることは明白だ。
松永英明氏がキヨシロー「Love me tender」のアンサーソングとしての斉藤和義「ずっとウソだった」の無力感［絵文録ことのは］2011/04/08でその対応関係を指摘している。
キヨシローの「放射能はいらねえ、牛乳を飲みてぇ」を受けて、斉藤は「風に舞う放射能はもう止められない」「ほうれん草食いてえな」と歌った。違うのは、放射能（放射性物質）はすでに放出されていることだ。
そもそも、タイトルやサビ自体がキヨシローへのアンサーである。斉藤の「俺たちを騙して、言い訳は「想定外」」「ずっとウソだったんだぜ やっぱ、ばれてしまったな」という歌詞が、キヨシローの「たくみな言葉で一般庶民をだまそうとしても ほんの少しバレてる、その黒い腹」という歌詞を受けているのは明白だ。23年前はほんの少しバレてる程度だったが、今や安全神話は崩壊した。
なお、「サマータイムブルース」の歌詞との対比を追記しておくと、「37個も建っている原発がまた増える」は斉藤の「原発が54基」、「それでもTVは言っている「原発は安全です」」は斉藤の「教科書もCMも言ってたよ、安全です」に受け継がれている。
これを見るだけでも斉藤が「騙された！」とは違った文脈で「ずっと嘘だった」を歌ったことが伺える。
何しろ斉藤は東海村JCO臨界事故の翌年2000年に発売したCOLD TUBEに収録した「青い光」で原発批判をすでにしているのだから。
青い光を見たんだ
とてもきれいな青だった
青い光を見たんだ
とてもきれいな青だった
ヘリコプターがハエのように・・・うまく思い出せない・・・
青い光を見たんだ
いつも通りにやったんだ
今日も髪がたくさん抜けた
斉藤は原発に対して、関心があり、懐疑心を持ち、曲を書き歌うことで反原発を訴えていた。
以上をふまえて本旨にツッコミを入れていこう。
どんな技術にもメリット・デメリットがある。メリットばかりを吹聴されて、それを盲信しないためには、科学的な懐疑心が欠かせない。われわれ日本人は、えてして道徳的な立場から人を疑うのはよくないことだと教えられるが、正しい判断をするために、いや「生きるために」、科学的懐疑心は必要なスキルだ。あらゆる意見は「仮説」として受け止め、反証できないか考える。検証されない仮説は採用しない。訓練は必要だが、なにも難しいことはない。人を疑うのではなく仮説を疑うのだから、道徳的にはなんの問題もない。
いやいや、あんたは斉藤和義が騙されて喚いてるって検証もしないで決めつけてるだろｗしかも人を疑ってるしｗ「訓練は必要だが、なにも難しいことはない（ｷﾘｯ」ってｗ面白すぎるｗ自分ができてないｗｗ
40代にもなって「騙された!」と騒ぐような情けない大人にならないためには、きちんとした科学教育が必要だ。それも、教科書を丸暗記すれば試験に合格するようなエセ科学教育じゃなくて、正当な懐疑心を養い、仮説検証を経ない理論は採用しないといった「科学の心」を持つための科学教育が。ちゃんと人を育てるところから始めないと、また数十年後におかしな責任転嫁を聴かされることになるよ。
「科学の心」を持つと科学以外のことに対する懐疑心は無くなっちゃうの？ただ氏が数年後におかしな責任転嫁を歌うことを楽しみにしてるよｗ

id:songe 清志郎へのアンサーソングなのに清志郎の歌を知らないもんだからこんなエントリーになっちゃった／知っててこのエントリーなら日本の言論的リテラシー教育の重要性が問われるな 2011/04/09
もちろん、知ってて当然だという反証は思い浮かべてました。そして、知ってたらこんなエントリーは書かないだろうとも思ったので確認の為にコメントしてみました。
「懐疑心を持つことが大切だ」というテーマのエントリーの導入部でいきなり決めつけから入っていたので。こんなことググれば十数分でわかることですし。
When the diesel generators were gone, the reactor operators switched to emergency battery power. The batteries were designed as one of the backups to the backups, to provide power for cooling the core for 8 hours. And they did.
Within the 8 hours, another power source had to be found and connected to the power plant. The power grid was down due to the earthquake. The diesel generators were destroyed by the tsunami. So mobile diesel generators were trucked in.
This is where things started to go seriously wrong. The external power generators could not be connected to the power plant (the plugs did not fit). So after the batteries ran out, the residual heat could not be carried away any more.
At this point the plant operators begin to follow emergency procedures that are in place for a “loss of cooling event”. It is again a step along the “Depth of Defense” lines. The power to the cooling systems should never have failed completely, but it did, so they “retreat” to the next line of defense. All of this, however shocking it seems to us, is part of the day-to-day training you go through as an operator, right through to managing a core meltdown.
It was at this stage that people started to talk about core meltdown. Because at the end of the day, if cooling cannot be restored, the core will eventually melt (after hours or days), and the last line of defense, the core catcher and third containment, would come into play.
But the goal at this stage was to manage the core while it was heating up, and ensure that the first containment (the Zircaloy tubes that contains the nuclear fuel), as well as the second containment (our pressure cooker) remain intact and operational for as long as possible, to give the engineers time to fix the cooling systems.
Because cooling the core is such a big deal, the reactor has a number of cooling systems, each in multiple versions (the reactor water cleanup system, the decay heat removal, the reactor core isolating cooling, the standby liquid cooling system, and the emergency core cooling system). Which one failed when or did not fail is not clear at this point in time.
So imagine our pressure cooker on the stove, heat on low, but on. The operators use whatever cooling system capacity they have to get rid of as much heat as possible, but the pressure starts building up. The priority now is to maintain integrity of the first containment (keep temperature of the fuel rods below 2200°C), as well as the second containment, the pressure cooker. In order to maintain integrity of the pressure cooker (the second containment), the pressure has to be released from time to time. Because the ability to do that in an emergency is so important, the reactor has 11 pressure release valves. The operators now started venting steam from time to time to control the pressure. The temperature at this stage was about 550°C.
This is when the reports about “radiation leakage” starting coming in. I believe I explained above why venting the steam is theoretically the same as releasing radiation into the environment, but why it was and is not dangerous. The radioactive nitrogen as well as the noble gases do not pose a threat to human health.
At some stage during this venting, the explosion occurred. The explosion took place outside of the third containment (our “last line of defense”), and the reactor building. Remember that the reactor building has no function in keeping the radioactivity contained. It is not entirely clear yet what has happened, but this is the likely scenario: The operators decided to vent the steam from the pressure vessel not directly into the environment, but into the space between the third containment and the reactor building (to give the radioactivity in the steam more time to subside). The problem is that at the high temperatures that the core had reached at this stage, water molecules can “disassociate” into oxygen and hydrogen – an explosive mixture. And it did explode, outside the third containment, damaging the reactor building around. It was that sort of explosion, but inside the pressure vessel (because it was badly designed and not managed properly by the operators) that lead to the explosion of Chernobyl. This was never a risk at Fukushima. The problem of hydrogen-oxygen formation is one of the biggies when you design a power plant (if you are not Soviet, that is), so the reactor is build and operated in a way it cannot happen inside the containment. It happened outside, which was not intended but a possible scenario and OK, because it did not pose a risk for the containment.
So the pressure was under control, as steam was vented. Now, if you keep boiling your pot, the problem is that the water level will keep falling and falling. The core is covered by several meters of water in order to allow for some time to pass (hours, days) before it gets exposed. Once the rods start to be exposed at the top, the exposed parts will reach the critical temperature of 2200 °C after about 45 minutes. This is when the first containment, the Zircaloy tube, would fail.
And this started to happen. The cooling could not be restored before there was some (very limited, but still) damage to the casing of some of the fuel. The nuclear material itself was still intact, but the surrounding Zircaloy shell had started melting. What happened now is that some of the byproducts of the uranium decay – radioactive Cesium and Iodine – started to mix with the steam. The big problem, uranium, was still under control, because the uranium oxide rods were good until 3000 °C. It is confirmed that a very small amount of Cesium and Iodine was measured in the steam that was released into the atmosphere.
It seems this was the “go signal” for a major plan B. The small amounts of Cesium that were measured told the operators that the first containment on one of the rods somewhere was about to give. The Plan A had been to restore one of the regular cooling systems to the core. Why that failed is unclear. One plausible explanation is that the tsunami also took away / polluted all the clean water needed for the regular cooling systems.
The water used in the cooling system is very clean, demineralized (like distilled) water. The reason to use pure water is the above mentioned activation by the neutrons from the Uranium: Pure water does not get activated much, so stays practically radioactive-free. Dirt or salt in the water will absorb the neutrons quicker, becoming more radioactive. This has no effect whatsoever on the core – it does not care what it is cooled by. But it makes life more difficult for the operators and mechanics when they have to deal with activated (i.e. slightly radioactive) water.
But Plan A had failed – cooling systems down or additional clean water unavailable – so Plan B came into effect. This is what it looks like happened:
In order to prevent a core meltdown, the operators started to use sea water to cool the core. I am not quite sure if they flooded our pressure cooker with it (the second containment), or if they flooded the third containment, immersing the pressure cooker. But that is not relevant for us.
The point is that the nuclear fuel has now been cooled down. Because the chain reaction has been stopped a long time ago, there is only very little residual heat being produced now. The large amount of cooling water that has been used is sufficient to take up that heat. Because it is a lot of water, the core does not produce sufficient heat any more to produce any significant pressure. Also, boric acid has been added to the seawater. Boric acid is “liquid control rod”. Whatever decay is still going on, the Boron will capture the neutrons and further speed up the cooling down of the core.
The plant came close to a core meltdown. Here is the worst-case scenario that was avoided: If the seawater could not have been used for treatment, the operators would have continued to vent the water steam to avoid pressure buildup. The third containment would then have been completely sealed to allow the core meltdown to happen without releasing radioactive material. After the meltdown, there would have been a waiting period for the intermediate radioactive materials to decay inside the reactor, and all radioactive particles to settle on a surface inside the containment. The cooling system would have been restored eventually, and the molten core cooled to a manageable temperature. The containment would have been cleaned up on the inside. Then a messy job of removing the molten core from the containment would have begun, packing the (now solid again) fuel bit by bit into transportation containers to be shipped to processing plants. Depending on the damage, the block of the plant would then either be repaired or dismantled.
Now, where does that leave us?
・The plant is safe now and will stay safe.
・Japan is looking at an INES Level 4 Accident: Nuclear accident with local consequences. That is bad for the company that owns the plant, but not for anyone else.
・Some radiation was released when the pressure vessel was vented. All radioactive isotopes from the activated steam have gone (decayed). A very small amount of Cesium was released, as well as Iodine. If you were sitting on top of the plants’ chimney when they were venting, you should probably give up smoking to return to your former life expectancy. The Cesium and Iodine isotopes were carried out to the sea and will never be seen again.
・There was some limited damage to the first containment. That means that some amounts of radioactive Cesium and Iodine will also be released into the cooling water, but no Uranium or other nasty stuff (the Uranium oxide does not “dissolve” in the water). There are facilities for treating the cooling water inside the third containment. The radioactive Cesium and Iodine will be removed there and eventually stored as radioactive waste in terminal storage.
・The seawater used as cooling water will be activated to some degree. Because the control rods are fully inserted, the Uranium chain reaction is not happening. That means the “main” nuclear reaction is not happening, thus not contributing to the activation. The intermediate radioactive materials (Cesium and Iodine) are also almost gone at this stage, because the Uranium decay was stopped a long time ago. This further reduces the activation. The bottom line is that there will be some low level of activation of the seawater, which will also be removed by the treatment facilities.
・The seawater will then be replaced over time with the “normal” cooling water
・The reactor core will then be dismantled and transported to a processing facility, just like during a regular fuel change.
・Fuel rods and the entire plant will be checked for potential damage. This will take about 4-5 years.
・The safety systems on all Japanese plants will be upgraded to withstand a 9.0 earthquake and tsunami (or worse)
・I believe the most significant problem will be a prolonged power shortage. About half of Japan’s nuclear reactors will probably have to be inspected, reducing the nation’s power generating capacity by 15%. This will probably be covered by running gas power plants that are usually only used for peak loads to cover some of the base load as well. That will increase your electricity bill, as well as lead to potential power shortages during peak demand, in Japan.

MvK2010
I'm going to copy paste a full blog post of a research scientist at MIT here, who explains the situation at Fukushima much better than anyone else has, his message: no worries.
This post is by Dr Josef Oehmen, a research scientist at MIT, in Boston.
He is a PhD Scientist, whose father has extensive experience in Germany’s nuclear industry. I asked him to write this information to my family in Australia, who were being made sick with worry by the media reports coming from Japan. I am republishing it with his permission.
It is a few hours old, so if any information is out of date, blame me for the delay in getting it published.
This is his text in full and unedited. It is very long, so get comfy.
I am writing this text (Mar 12) to give you some peace of mind regarding some of the troubles in Japan, that is the safety of Japan’s nuclear reactors. Up front, the situation is serious, but under control. And this text is long! But you will know more about nuclear power plants after reading it than all journalists on this planet put together.
There was and will *not* be any significant release of radioactivity.
By “significant” I mean a level of radiation of more than what you would receive on – say – a long distance flight, or drinking a glass of beer that comes from certain areas with high levels of natural background radiation.
I have been reading every news release on the incident since the earthquake. There has not been one single (!) report that was accurate and free of errors (and part of that problem is also a weakness in the Japanese crisis communication). By “not free of errors” I do not refer to tendentious anti-nuclear journalism – that is quite normal these days. By “not free of errors” I mean blatant errors regarding physics and natural law, as well as gross misinterpretation of facts, due to an obvious lack of fundamental and basic understanding of the way nuclear reactors are build and operated. I have read a 3 page report on CNN where every single paragraph contained an error.
We will have to cover some fundamentals, before we get into what is going on.
Construction of the Fukushima nuclear power plants
The plants at Fukushima are so called Boiling Water Reactors, or BWR for short. Boiling Water Reactors are similar to a pressure cooker. The nuclear fuel heats water, the water boils and creates steam, the steam then drives turbines that create the electricity, and the steam is then cooled and condensed back to water, and the water send back to be heated by the nuclear fuel. The pressure cooker operates at about 250 °C.
The nuclear fuel is uranium oxide. Uranium oxide is a ceramic with a very high melting point of about 3000 °C. The fuel is manufactured in pellets (think little cylinders the size of Lego bricks). Those pieces are then put into a long tube made of Zircaloy with a melting point of 2200 °C, and sealed tight. The assembly is called a fuel rod. These fuel rods are then put together to form larger packages, and a number of these packages are then put into the reactor. All these packages together are referred to as “the core”.
The Zircaloy casing is the first containment. It separates the radioactive fuel from the rest of the world.
The core is then placed in the “pressure vessels”. That is the pressure cooker we talked about before. The pressure vessels is the second containment. This is one sturdy piece of a pot, designed to safely contain the core for temperatures several hundred °C. That covers the scenarios where cooling can be restored at some point.
The entire “hardware” of the nuclear reactor – the pressure vessel and all pipes, pumps, coolant (water) reserves, are then encased in the third containment. The third containment is a hermetically (air tight) sealed, very thick bubble of the strongest steel. The third containment is designed, built and tested for one single purpose: To contain, indefinitely, a complete core meltdown. For that purpose, a large and thick concrete basin is cast under the pressure vessel (the second containment), which is filled with graphite, all inside the third containment. This is the so-called “core catcher”. If the core melts and the pressure vessel bursts (and eventually melts), it will catch the molten fuel and everything else. It is built in such a way that the nuclear fuel will be spread out, so it can cool down.
This third containment is then surrounded by the reactor building. The reactor building is an outer shell that is supposed to keep the weather out, but nothing in. (this is the part that was damaged in the explosion, but more to that later).
Fundamentals of nuclear reactions
The uranium fuel generates heat by nuclear fission. Big uranium atoms are split into smaller atoms. That generates heat plus neutrons (one of the particles that forms an atom). When the neutron hits another uranium atom, that splits, generating more neutrons and so on. That is called the nuclear chain reaction.
Now, just packing a lot of fuel rods next to each other would quickly lead to overheating and after about 45 minutes to a melting of the fuel rods. It is worth mentioning at this point that the nuclear fuel in a reactor can *never* cause a nuclear explosion the type of a nuclear bomb. Building a nuclear bomb is actually quite difficult (ask Iran). In Chernobyl, the explosion was caused by excessive pressure buildup, hydrogen explosion and rupture of all containments, propelling molten core material into the environment (a “dirty bomb”). Why that did not and will not happen in Japan, further below.
In order to control the nuclear chain reaction, the reactor operators use so-called “moderator rods”. The moderator rods absorb the neutrons and kill the chain reaction instantaneously. A nuclear reactor is built in such a way, that when operating normally, you take out all the moderator rods. The coolant water then takes away the heat (and converts it into steam and electricity) at the same rate as the core produces it. And you have a lot of leeway around the standard operating point of 250°C.
The challenge is that after inserting the rods and stopping the chain reaction, the core still keeps producing heat. The uranium “stopped” the chain reaction. But a number of intermediate radioactive elements are created by the uranium during its fission process, most notably Cesium and Iodine isotopes, i.e. radioactive versions of these elements that will eventually split up into smaller atoms and not be radioactive anymore. Those elements keep decaying and producing heat. Because they are not regenerated any longer from the uranium (the uranium stopped decaying after the moderator rods were put in), they get less and less, and so the core cools down over a matter of days, until those intermediate radioactive elements are used up.
This residual heat is causing the headaches right now.
So the first “type” of radioactive material is the uranium in the fuel rods, plus the intermediate radioactive elements that the uranium splits into, also inside the fuel rod (Cesium and Iodine).
There is a second type of radioactive material created, outside the fuel rods. The big main difference up front: Those radioactive materials have a very short half-life, that means that they decay very fast and split into non-radioactive materials. By fast I mean seconds. So if these radioactive materials are released into the environment, yes, radioactivity was released, but no, it is not dangerous, at all. Why? By the time you spelled “R-A-D-I-O-N-U-C-L-I-D-E”, they will be harmless, because they will have split up into non radioactive elements. Those radioactive elements are N-16, the radioactive isotope (or version) of nitrogen (air). The others are noble gases such as Xenon. But where do they come from? When the uranium splits, it generates a neutron (see above). Most of these neutrons will hit other uranium atoms and keep the nuclear chain reaction going. But some will leave the fuel rod and hit the water molecules, or the air that is in the water. Then, a non-radioactive element can “capture” the neutron. It becomes radioactive. As described above, it will quickly (seconds) get rid again of the neutron to return to its former beautiful self.
This second “type” of radiation is very important when we talk about the radioactivity being released into the environment later on.
I will try to summarize the main facts. The earthquake that hit Japan was 7 times more powerful than the worst earthquake the nuclear power plant was built for (the Richter scale works logarithmically; the difference between the 8.2 that the plants were built for and the 8.9 that happened is 7 times, not 0.7). So the first hooray for Japanese engineering, everything held up.
When the earthquake hit with 8.9, the nuclear reactors all went into automatic shutdown. Within seconds after the earthquake started, the moderator rods had been inserted into the core and nuclear chain reaction of the uranium stopped. Now, the cooling system has to carry away the residual heat. The residual heat load is about 3% of the heat load under normal operating conditions.
The earthquake destroyed the external power supply of the nuclear reactor. That is one of the most serious accidents for a nuclear power plant, and accordingly, a “plant black out” receives a lot of attention when designing backup systems. The power is needed to keep the coolant pumps working. Since the power plant had been shut down, it cannot produce any electricity by itself any more.
Things were going well for an hour. One set of multiple sets of emergency Diesel power generators kicked in and provided the electricity that was needed. Then the Tsunami came, much bigger than people had expected when building the power plant (see above, factor 7). The tsunami took out all multiple sets of backup Diesel generators.
When designing a nuclear power plant, engineers follow a philosophy called “Defense of Depth”. That means that you first build everything to withstand the worst catastrophe you can imagine, and then design the plant in such a way that it can still handle one system failure (that you thought could never happen) after the other. A tsunami taking out all backup power in one swift strike is such a scenario. The last line of defense is putting everything into the third containment (see above), that will keep everything, whatever the mess, moderator rods in our out, core molten or not, inside the reactor.

My mom got jumped -- they ran!
母親が飛ぶとあいつらは走るから
Now I'll play a public servant
警察と今遊んでるのさ
To serve and protect
奉仕して、守って
By the law and the state
法と国家によって
I'd bust the punks
That rape steal and murder
And leave you be
お前をそんなふうにして
If you crossed me
俺ともう一回会えるなら
I'd shake your hand like a man
Not a god
神じゃなくて
(Chorus)
Come meet your maker, boy
お前の親父に会わせろよ
Some things you can't enjoy
享受できないことだってあるさ
天国と地獄のせいさ
A fucking wives' tale
糞みたいな物語を
They put it in your head
あいつらがお前の頭の中に入れて
Then put you in your bed
ベッドのそばで子守唄にする
He's watching say your prayers
お前のために祈ってる奴を見ろってあいつは言うなあ
Cause God is everywhere
神様はどこにでもいるからだってさ
Now I'll play a man learning priesthood
じゃあ俺は聖職者に付き従ってる男の役でもやってみよう
Who's about to take the ultimate test in life
誰が人生最大の問いなんてものを投げかけてきても
I'd question things because I am human
俺は人間だから答えてやろう
And call NO ONE my father who's no closer than a stranger
知らない奴より神様に近い奴なんていなんだ
I won't listen
聞きたくもないんだ
To see
見てみろ
To bleed
血を流してみろ
Cannot be taught
教えられることじゃねえ
In turn
次々に
You're making us
お前が俺をつくってるんだな
Fucking, fucking, fucking
糞みたいに
FUCKING HOSTILE!
お前は敵対的なんだ
安らかに眠れ

☆女の徒然草☆というサイトが騒いでる、「はじめまして★」さんが、詐欺行為を働いてるというはなし。
その「はじめまして★」さんのサイトをみてきた（ttp://blogs.yahoo.co.jp/dofootred6）
どこらへんが見るとやばいのかな？と思いきや、
『花より男子より井上真央の子役時代お宝動画』とかから『井上真央の子役時代お宝動画はこちら』をクリックして、こちら（ttp://gal.s92.coreserver.jp/tube/index.avi）に行き、再生ボタンを押下し、二度の警告に『はい』を押すと、料金請求にくる…というだけのものだった。
えっと、これに注意を促すためだけに、あんなに転載させて、活動監視したりしてるんだ…
バカじゃないの？と。
ごめん、誹謗・中傷扱いになっちゃうかもしれないけど、マジでそう思った。
もし、この件が落ち着いて、そしたら、あちこちに転載された記事をどう収拾つけるつもりなんだろ。
このまま放置されてて、すでに沈静化した後も、さらに転載先からさらなる転載を繰り返して…
もう、こうなったらスパムと何ら変わらないよな（まぁ、そういう意味ではYAHOOブログの転載ＯＫてリテラシーも何も考えてない酷い機能なんだが）
沈静化した後に、今回の「はじめまして☆」という人と無関係な同一の名前の人が活動はじめたら、その人は何もしてなくても叩かれる可能性もあるってことだよなぁ。転載させることって凄く怖いと思うよ。
そもそも、この人、よくわかんないんだよね。

せっかく、構想３日、製作１日ではなく、ＧＩＦ保存や、画像の分数比による拡大縮小などのプログラム作りまで行った上で複数のソフトを駆使して製作した画像なのです。
…画像を拡大縮小するソフトをわざわざ３日かけて作る意味がわからない。もし本当だとしたら、余程ダメなプログラマだし。

もし、お使いになりたい方がいらっしゃいましたら、この記事を転載の上、右クリックでアドレスを調べてから、

で必要な場所に表示してくださいね。
…これだってさ、直リンクの説明じゃん？（まぁ、帯域も太いご時世だし、YAHOOの同一サーバ内の参照だし、て思うけど、このやり方で憶えちゃったら他サーバであろうと好きに直リンクしちゃうよねぇ？と。初心者への説明としては宜しくないと思うけどな）
つか、いろいろ間違ってしまうこともあるだろうけど、あんなに高圧的な文章を書かれたら反感買うの必至だろうに。
昔からネットやってるっていうけど、自分が正しくて、相手を受け入れない姿勢（リンクの不許可や、気に入ったコメントのみを受け入れる姿勢とか）は、どうかと思うよ？そりゃ、叩かれるのもムリない。
あぁ、ひょっとして、よっしみ??☆って人は、釣りでやってるん？ｗ

WHITE TENGAのAIR CUSHION CUPを試した。
RED TENGAのSOFT TUBE CUPと比べるとソフトにまとわりつく感じだ。しかしやはり自分からする小さく窮屈目。
あと、値段が高い。1400円くらいした。RED TENGAのSOFT TUBE CUPは700円くらいだった。
倍も違う！
今度はUS TENGAのSOFT TUBE CUPを試してみようか。
