疫情又再肆度虐,今天60新增個案。
今朝處理啲corporate accounts 朋友訂購Antigen快速測試棒。
WFH,忙足一天。
今天很多是我認識的朋友找我:
體育界,教練,學校,
還有些是外國人,活躍中西區半山的,
希望他們都沒有事。
這兩天他們其中一個常遇問題:
其實可以戴甚麼口罩做運動?
這個我其實一直在探討,
直入專業口罩廠開會研究,
昨天就有個會議,開到晚上8點。
(多謝K Kwong 和山系柳爺同我去開會)
我一直想研究特定用途 / 專業用的口罩,
例如廚房裡用甚麼口罩,運動用甚麼口罩,
健身用甚麼口罩,run and hike又用甚麼口罩。
現在談的是一種會死人的疫症,
又有一些不能避免的工作和活動,
是需要用多點心思去做好的。
外國人和大頭仔也是有需要特別照顧,
他們戴普通175mm口罩都會太緊,
又由於高鼻,鼻帶不貼面也等於沒用。
加上他們可能運動量大,
常見有把口罩拉下來抖氣,
這其實是很觸目驚心的。
我希望做到真正讓人在專業地工作和做運動時,
都戴得舒適的口罩。
(暫時進度是緩慢的,睇緊sample,
因為成本真的很貴,
數量和用料也是個問題,我努力。)
目前,我會推薦救世Savewo的Ultra口罩
給做運動和健身行山的朋友。
Level 3及強隔濾這些不用多講,
Savewo面層用料Ultra Spun Bond 通過潑水測試,
基本上是防水的。
立體設計,口罩底層不會貼著鼻孔和口,
而我們所說的「焗唔焗」、「抖唔抖到氣」-
空氣阻力是可以量度的,
Ultra 系列的空氣阻力Delta -P < 2.4mm
在市面上應該是 (level 3中)最低(可能無之一)
尺碼有S碼給小面,M碼成人,L碼給外國人,白色。
各位乖啦,
當外圍情況不保障我們時,
我們要幫自己,及要互相幫助。
傳播及初傳播疫症人命關天,
被迫去打疫苖也是人命關天。

差不多整齣《三更之回家》在中環前已婚警察宿舍拍攝。Eric與家人住在南座一個單位,Leon與死去的妻子則住北座。數百米的平台是分隔又是維繫他們的空間。
當我們拍這部戲的時候,宿舍已人去樓空,準備發展成今日我們看得見的商場,成為了我們的片場,屬於我們的攝影棚。
我們沒有錢,又沒有特別的美術偏好,添置甚麼來改變這空間。但怎樣善用這裡?如何讓空間「有話說」?戲劇性和視覺震憾的地方在哪?由於空間是電影的主角,如何將它發揮得淋漓盡致,展現它與有生命又有呼吸的角色有何關係?
所以我們測試燈光,測試Leon 「治療」妻子的草本水顏色。我們又做出不同構圖,看如何拍好這偌大的空間,又不會讓演員湮沒其中(我們都想看到演員在做甚麼,也想大家感受演員感受到的空間)
在開拍前花點時間測試,不單止提供有用的資訊,同時也是好方法,凝聚團隊間的力量。助理不只是「助你」,他們也投入測試看是否可行。有句話是對的,花時間琢磨細節便會做出細節,玉不琢不成器。
Almost all of Three, Going Home takes place inside the PMQ compound in Central. Eric and his family have a flat in the Southern block. Leon and his dead wife live in the Northern block. A hundred square metres of courtyard are all that separates or perhaps joins them.
The married police had long gone when we shot the film, and it’s development into the shopping space it is now was some years away , so we had a ready made “ back lot ”. We had a studio of our own.
We had neither the money nor the intent “ art direct ” or add this or that
to change the space. But how best to use it? What is the space “saying” ? What is dramatic, or visually compelling? Since the space is a main character in the film, how to bring out the best in it, as one has to do with any of the living, breathing characters?
So we tested light, we tested the colour of the herbal waters Eric “cures” his wife with. We try to work out what frame presents enough of the space without the actors disappearing in the space ( we want to see what they are doing , but we also want to feel the space in which they do it ) ….
Taking the time to prepare a film like this is not just informative; it is a great way to focus a teams energies ; assistants are not just assisting they are engaged in how something works or not. And yes, taking the time to go into details helps make the details themselves have a potential they would otherwise not have.

Alumine Five of Stenheim
Stenheim is a relatively late entrant to the high-end speaker field. It was founded in 2010 by a collective of mainly ex-Goldmund engineers, and its products have inherited an unmistakable aesthetic and, to a lesser extent, sonic DNA, although it was a significantly evolved character that was to emerge in the shape of the debut model, the compact, two-way Alumine Two. It’s a developmental divergence that has continued and, if anything, accelerated with the emergence of each subsequent product. The latest Stenheim speakers, developed under the auspices of new owner Jean-Pascal Panchard, definitely have their own, unambiguous identity, both visually and musically.
I’ve been seriously looking forward to the arrival of the Alumine Five. Previous experience with the brand has included impressive exposure to the various versions of the enormous and enormously impressive Ultime Reference models, as well as a brief but highly rewarding flirtation with the stand-mounted Alumine Two in my own system. The possibility of combining the sense of musical articulation, enthusiasm and communication I experienced from the Alumine Two, with more than a hint of the clarity, scale and authority so effortlessly delivered by the Reference models, all in a package that, if not exactly affordable, at least isn’t completely out of the question, makes the Alumine Five a distinctly interesting proposition.
Yet, confronted with the Alumine Five in the flesh, there’s little to hint at the extraordinary promise lurking within. Resolutely rectangular in true Stenheim style, the Five’s aluminum cabinet, with its plate-to-plate construction, stands just 48" tall, 15" deep and presents a broad 11" face to the world, dimensions based on golden-ratio numbers. The front baffle is split by a physical break between the upper midrange-treble enclosure and the lower bass cabinet, independently ported by the laminated full-width slots above and below, a physical separation that is mirrored by the contrasting inlaid strips that help visually break up the one-piece side panels. The regular lines, smooth surfaces, flawless matte finish and lack of visible fixings could easily result in a bland, almost featureless appearance. But those trim strips and the offset midrange and treble drivers do just enough to give the Five a subtle hint of individual style without resorting to the sort of gauche and ostentatious flourishes that so often pass as design.
The result is a refreshingly clean, classical appearance that will blend seamlessly with a range of different decors. Despite the lack of grilles (although they are available as an option, does anybody really spend this kind of money on a speaker and then compromise the performance by fitting covers?), the beautifully profiled baffle and absence of visible fixings makes for a genuinely neat, finished appearance that matches the superb surface finish on the cabinet. The end result just looks right, in a way that makes you wonder why you’d want grilles anyway.
The first hint of its potent sonic capabilities comes when you try to pick it up. Each comparatively compact cabinet tips the scales at 220 pounds. That’s a grunt-inducing, two-man lift. Now, take a look at the figures for bandwidth and sensitivity, and an in-room response that digs down as far as 28Hz combined with 94dB efficiency should raise your eyebrows, especially given the compact cabinet dimensions. Which brings us to the first experiential disconnect: boxes this size shouldn’t produce this much bass or do it so easily. Nor should they weigh so much -- although therein lies the clue to this particular conundrum. When it comes to bass extension, it’s not the external dimensions of the box that matter, but its internal volume. Just like the Crystal Cable Minissimo, a thin-wall cabinet makes for a much larger internal volume than the external dimensions might suggest -- especially if we apply the expectations of more conventional wood-based construction. Throw in the sheer weight of the aluminum panels and the combination of mass and physical dimensions would subconsciously suggest massively thick walls -- and a correspondingly limited internal volume. Instead, what we have here is a deceptively large volume, which, combined with the inertia of the heavy cabinet and the mechanical stability provided by the material, makes for an effective mechanical reference for driver movement, meaning that more of the energy your amplifier sticks into the speaker comes out as sound and (at least in theory) it will be more precisely rendered.
So far, not very much that’s new. It’s not like Stenheim (or Magico, or YG Acoustics) has exclusivity when it comes to aluminum cabinets. But what does make Stenheim different is the unique material they use in damping their cabinet panels. Of course, the separate enclosures and the internal baffles they demand make for an inherently heavily braced structure, but look inside a dismantled Alumine Five and you’ll find strategically placed pads stuck to the cabinet walls. These three-layer, self-adhesive pads combine a heavy damping layer (adjacent to the cabinet wall itself) with added foam and impervious layers, allowing the low-volume pads to influence both the mechanical behavior of the cabinet itself and the enclosed volume. It’s an interesting solution because it manages to overcome the weakness so often audible in simple, braced aluminum cabinets (the all-too-recognizable resonant signature of the material itself) while maximizing the benefits (large volume and rigidity) by obviating the need to stuff the internal space full of wadding or long-haired wool. In fact, if the Stenheims were stood behind a sonically transparent curtain, you’d be hard-pressed to recognize the music as emanating from an aluminum cabinet at all. The absence of the bleached, grainy or lean colorations, the lack of sterile, mechanistic reproduction, is one big half of the Stenheim story, living, breathing proof that it’s not what you use but how you use it that counts.
The other half is down to the drive units, and after the cabinets, those come as quite a surprise, both the lineup and the chosen materials. In stark contrast to the use of the latest, precision CNC techniques, complex damping pads and finishing options, the Alumine Five's drivers are as traditional as they come, with a coated silk-dome tweeter and pulp or laminated paper midrange and bass drivers. The cone drivers use textile double-roll surrounds and massive magnets more normally found in pro-audio applications, and while Stenheim doesn’t build its own drivers, the company works closely with its chosen supplier (PHL, definitely not one of the usual suspects) to specify the electrical parameters, mechanical characteristics and precise details of the surface coating.
The use of such lightweight cone materials and large motors aids the system efficiency, while a hybrid second-order/Linkwitz-Riley crossover, the result of extended listening and evolution, ensures phase coherence and excellent out-of-band attenuation and makes for easy non-reactive load characteristics, despite the three-way topology. The other aspect of the driver lineup that might be considered slightly unusual is the use of a large-diameter (6 1/2") midrange unit -- although less so since Vandersteen’s patent on the approach lapsed some years ago, resulting in a rash of companies suddenly exploring the possibilities of the topology.
Perhaps more important, in the case of the Alumine Five, it means that you are getting the tweeter and midrange drivers from the Ultime Reference series speakers, teamed here with a pair of 10" woofers but without the benefit of a super tweeter. Even so, Stenheim quotes bandwidth out to 35kHz, which should suffice for most purposes. The review speakers arrived with the optional second set of terminals installed, allowing for biwiring or, more significantly, biamping, an upgrade opportunity that makes this an option you should take. If, in the meantime, you are single-wiring the speakers, make sure you factor in a set of jumpers that match your speaker cables: the Alumine Five's overall sense of musical coherence makes the benefits especially obvious. Likewise, good wiring practice is essential, both in terms of cable dressing and diagonal connection (red to midrange/treble, black to bass, with jumpers arranged accordingly).
Aside from the speaker's substantial weight, the parallel sides and flat surfaces of the four-square cabinet make setting up the Fives an absolute joy. Precise, repeatable, angular adjustments are easily achieved, while changes in attitude are just as straightforward, helped by the beautifully profiled stainless-steel spiked feet and deeply cupped footers. Both the cones and their locking rings have nice, large ports to take the supplied pry bars, but it’s worth greasing the threads before installation. One other thing to watch out for: the spikes are seriously (refreshingly) sharp -- sharp enough to penetrate a thick rug and score the floor below, so be careful where you stand the speakers once the feet are installed. Final positioning disposed the speakers on a broad front with minimal toe-in. When it came to dialing in their considerable musical energy, the most critical factor proved to be height off the ground, with tiny adjustments of the spikes making profound differences to the weight and pace of the presentation. Likewise, equal weighting of the four spikes was crucial to a proper sense of grounded weight and dynamic authority.

square breathing 在 Yoga with Andrea Youtube 的評價
It’s common for us to have shoulder tightness, neck stiffness and rounded backs with our daily habits; you know what they are.
Here are some really good stretches you can do anywhere and anytime ! You can pick and choose your favourite and doing 3-5 rounds of at least 3 types of mobility and openings stretches can do wonders for your neck, shoulders and upper spine.
In this video you can incorporate breathes on each movement. The trick is to find which posture is an opening movement and breathing into the opening and exhale into the closing of the posture.
* shoulder mobility circle clockwise and anti clockwise x 5
* Side body stretch; twist your torso up to the sky for opening of the chest and collar area. Stay for 3-5 breathes and you can deepen the stretch by bring your elbow close to the ground. Repeat on both sides.
*Box stretch - shoulder to the right, front, left and back drawing a square with your upper body. Repeat 3-5 rounds and on both sides.
*Pixie dust (that’s what I like to call it) swinging the arm straight and up imagine throwing the arms away trying to detach it from the body; for throwing pixie dust into the sky ! Repeat both side clockwise and anti clockwise.
*Seated cat and cow to open up the chest and back, front collar area and back shoulder blades. Repeat for 3-5 rounds.
* Eagle arms right and left side, lifting up on the inhale and down on the exhale. Repeat 3-5 times each arm.
*Prayer palm presses, repeat 3-5 times. Prayer palms,
Pressing firmly to the middle of your check and inhale pressing forearms together fingers to the sky.
Lastly, restorative. You can use blocks, books, chair or anything you can find in the house to elevate your arms.
*Shoulder opening 1 minute. Option to deepen is pressing the palms on your upper back.
*Restorative fish posture. If you back is stiff keep the knees bent. Stay for 2 minutes. After 2 minutes if you want to deepen the pose remove the block from behind your head and stay for an additional 1 minute. Come up slowly to avoid blood rush and dizziness.
Option to finish off in savasana.
