張競》過度回應共機 弄巧成拙

張競》過度回應共機 弄巧成拙

立院審預算,共機又來,馮世寬臨時請假回部坐鎮

共軍運8遠干型機。國防部提供。

近日共機頻繁穿越島鏈展開演訓,再加上派機航經對馬海峽,進入日本海實施航訓;同時解放軍配合此等演訓動態刻意以高調表態,更是受到各方關注。如何持平論斷前述活動虛實,不盲目起舞或過度反應,以免對國家投資環境產生負面效應,考驗著主政者智慧。

首先須強調,前述共機活動空域皆為國際空域,其所作所為均依當前國際法規範,更無對任何國家產生實際侵略情事。對於如何解讀共軍意圖,各方觀點雖然見仁見智,但周邊各國確實從未有任何政府,循正式外交管道向北京遞送過抗議照會,倒是不爭的事實。

其次,此等演訓內容並未明確與任何作戰構想或計畫配套;所有從共機動態所衍生之臆測,其實無法證明其未來所將採取的軍事選項,更無法就其動態上綱認定為敵意增高,或是即將運用軍事手段改變當前現況。

人類經常準備與期待的戰爭,不是從未發生,就是完全跌破眾人眼鏡。911事件前無人預見到日後美軍將全力投入全球反恐,以及入侵伊拉克與阿富汗。所以推估未來戰爭,事前不宜鐵口直斷,事後更別鐵齒。台灣人不是被嚇大的,在台海軍事對峙最嚴重的歲月中,我們還創造出經濟奇蹟,民眾無畏於軍事威脅,都仍能安居樂業。

現在共機在台灣周邊稍微有所活動,就搞到國防部長與參謀總長要坐鎮指揮,擺出天下安危繫於一身的架勢。日前適逢立法院審國防預算,國防部長卻為了共機遠航長訓請假跑回指揮所,莫非是為了躲避立委炮轟?當兩岸氛圍糟到夜半敲門心驚恐時,我們是否要反省為何會這樣恐慌?

假若當前政府決心要保持現行政策,不知真誠面對兩岸僵局,非要讓全球將台灣評估成未來世界大戰引爆的熱點,這對於發展經濟、鼓勵投資來說,會有正面效益嗎?軍事首長動輒高調反應,又操作媒體,這是執政者所要塑造的氛圍嗎?

儘管共機動態確實顯現出共軍實力有所增強,但畢竟無法由此推估出北京所有的政策決心與行動意圖。各界仍須務實思考所有徵候,目前這些動態只是單隻燕子飛翔,並不足以代表整個節氣變化,政府不必動輒誇大事實,嚇唬老百姓。

運用共機操弄政治,要是弄巧成拙,可能賠了夫人又折兵,讓社會投資信心受損,到那時就更加證明執政無能了。

Satellite Activity From Azores Islands on Christmas

Pedro, CU2ZG says he will be active on satellites from grid square
HM58 on Christmas.

His equipment will include an Alaskan Arrow antenna, Yaesu FT-817ND,
Yaesu FT-857D, Kenwood  TS-2000 and a Wouxun KG-UV9DPlus. Most of
the operation will be done  using the TS-2000.

Expected operating days are December 23 and 24, plus December 25
during the afternoon/evening hours. Pedro says this will be a family
holiday and skeds will be accepted depending on his availability.
His exact location will be HM58qm, at the CU7BC QTH (check QRZ.com)
Watch his twitter account (@pdsousa) for updates.

December 20 Launch for HA-1 CubeSat with FM transponder and SSTV

The IARU has announced frequency coordination has been completed for
HA-1, a 2U CubeSat developed by the Teenagers Amateur Radio Center of
Activity in Huaian, China. HA-1 is planned for launch on December 20.

HA-1 will be mainly used for teenagers in Huaian to carry out
activities
related with amateur radio and aerospace science education. The
cubesat
is equipped with amateur radio repeater and SSTV(Slow Scan Television)
component, which is to validate still image transmission in narrowband
voice channel.

There is an SSTV beacon, which puts Date/Time/Location
information/temp-
erature etc on a SSTV picture. Amateurs worldwide can also use HA-1 to
test SSTV via the cubesat.

Uplink:    145.930 MHz FM
Downlink:  436.950 MHz FM
Telemetry: 437.350 MHz 9k6 BPSK

Information for Requesting UT1FG/MM QSL Cards

John, K8YSE, posted a message on the amsat-bb on behalf of Yuri,
UT1FG/MM currently at sea aboard the MV Seahorse, “Yuri has asked
that anyone who has not received confirmations from this year and
previous year’s operations to prepare logsheets so that he can mail
them out when he arrives in New Orleans.”

John has posted an Excel Spreadsheet for you to enter your log data
plus an example of a completed log sheet at:
http://www.papays.com/sat/ut1fgqsl.html

John’s web page includes instructions to prepare your logsheet of
QSO’s
that Yuri can print, verify, sign and mail from one of his destination
ports. E-mail your logsheet to John at the address he lists in his
instructions. John will send an acknowledgement email when he receives
your request. This way you will know that Yuri will have your
logsheet.

Marinetraffic.com anticipates a December 15-16 arrival in New Orleans.
John requests you send your logsheet QSL request as soon as possible
so Yuri will have time to get them ready for mailing.

Yuri’s current ship, Seahorse, is a relatively new ship and is wider
than previous vessels he has captained so it cannot go through the
locks in the Great Lakes. On this voyage he will be more restricted
as to possible destinations than he was last season.

John concluded, “Yuri has been very busy with his duties and has
had little time for anything else. He sends his regards to all.”

Two-Part Video Demonstration Working AO-91 from Down Under

Peter Parker, VK3YE, has published two excellent introduction to
amateur satellites videos. Note that some of the QSO customs shown
are a little different than the common practice in Europe and North
America, but the tips are still generally applicable.

Peter, VK3YE, describes his two-part video demonstration as,
“A new amateur satellite has just gone up and it’s super easy to
work. You just need a pair of handhelds on 2m & 70cm FM.  Watch
this video to find out how to make contacts through AO91 with
equipment you probably already have.”

KG5CCI and F4DXV 7,634.775 km QSO Sets New Distance Record on FO-29

David Swanson, KG5CCI, and Jerome Lecuyer, F4DXV completed a
7,634.775 km QSO on December 12 via FO-29. This eclipses their
previous record on that satellite by 26.62 km and greatly
exceeds the theoretical maximum range of the satellite,
which is calculated at 7,502 km. Video of the QSO as recorded
by F4DXV can be viewed at:

華盛頓大學最新研究將DNA上植入惡意軟體成功入侵電腦?

DNA示意圖。 圖/ingimage

DNA操控著人類的基因,在科學中DNA編纂技術應用於生物武器研發可能威脅到生物或人類的概念不難理解,但現在似乎可以威脅到電腦了。利用DNA入侵電腦聽起來像是Michael Crichton的小說情節,不過最近真的有研究人員將DNA遺傳分子植入惡意軟體並藉此控制電腦。

在號稱是首次利用DNA成功入侵電腦軟體的實驗,為了開發這個惡意軟體,華盛頓大學研究人員TadayoshiKohno和LuizCeze領導團隊把簡單的電腦指令翻譯成176個DNA字符組成的片段,以DNA上起配對作用的部分的鹼基A、G、C、T的形式表示。他們花了美金89元從網路上買來一小段DNA上編寫病毒,他們將這些DNA鏈放進測序儀,由其讀取基因字元,然後以0和1的形式儲存為二進制代碼(A=00,C=01,G=10,T=11)在電腦處理由DNA測序儀讀取遺傳數據時,掌控了整台電腦。詳細研究內容可參考此

此次攻擊利用了緩衝區溢位,使得超出存儲緩衝區的數據被解讀為電腦指令。這樣一來,這個命令就會聯繫一台由Tadayoshi Kohno團隊掌控這台用於分析DNA數據的電腦。這次的DNA惡意軟體研究將在下週溫哥華的Usenix Security Symposium大會上展示。透過此研究新興技術,未來他們將持續是否存在可以證明的安全威脅,進行提前的應對和防範。研究人員認為,他們未來或許還會需要對DNA序列進行檢查,以便排除電腦可能面臨的威脅。

研究人員警告未來這樣的技術可能製造出假的血液或唾液樣本入侵醫院的電腦或是盜取實驗室的機密。目前許多實驗室所使用的開源軟體都有漏洞,他們認為DNA轉錄和分析在基礎的安全建維護上十分不足,未來可能會遭到迫害。

不過他們也坦言,在入侵實驗中已關閉電腦某些安全功能,此外在技術上要將載有惡意軟體的DNA鏈從樣本導入定序儀是非常困難挑戰,即使在在過程中能順利地將它放入排序器進行排序,可能會因太分散無法讀取。

隨著近幾年關於DNA結合生物學與資訊學的研究越來越多,不管是將資料存於DNA中的技術,或像是在上個月Nature期刊有來自哈佛的科學家成功將一張GIF動圖儲存在活生生的大腸桿菌上,利用DNA技術的駭客現在看來似乎也不是很遙遠。
