My Rambling Thoughts

Getting started with music

A 61-key foldable digital keyboard with touch-sensitive keys, bluetooth and light-up keys. All for 199 yuan (S$37.30). Pay another 30 yuan to get a pair of earphones, keyboard cover, single-foot pedal and a bag.

The base model (non-touch-sensitive keys, no bluetooth and no light-up keys) is a mere 119 yuan (S$22.30). The bluetooth model (no light-up keys) is 169 yuan (S$31.60).

The keys are only 20 mm wide. Only 88-key keyboards offer 22 mm keys.

The weight is not stated, but based on a similar model from another maker, it should be around 2.0 kg.

The speaker power is also not stated. Based on similar products, it should be dual 2W speakers.

At this price, you can't expect too much quality. The key selling points are portability and light-up keys.

Super wide binos

I was able to find super wide binos all of a sudden.

These binos all have FMC, phase correction coating and dielectric reflective coating.

I did not know APO was a thing for binoculars. Nor had I heard of BAK4-HT.

Light transmission is rarely mentioned. It seems the practical max for a roof bino is 93%. 89% is pretty good. If not mentioned, fully multi-coated (including prism) should be around 85%. Fully single-coated is said to be 75%.

SAGA has 3 lines of binos: 猎鹰 (low-end), 飞鹰 and 猎峰. 飞鹰 has normal and ED variants. 飞鹰 8x42 is 449 yuan, 8x42 ED is 811 yuan. Some shops say the 449 yuan model has ED glass, but the official website (sagaoptics.com.cn) states otherwise.

BOSMA X is the only shortlisted 8x32 bino. There are few 8x32 binos with FOV more than 8°.

BOSMA 青龙 has the best spec I've seen so far, but its price is also incredible — and it is heavy too. There is no free lunch.

Another 8x32 bino contender

When the Forrester bino was on its way to me, I continued to look up more 8x32 binos.

To my surprise, I saw a couple of reviewers singing the praises of the US$100 Svbony SV202 bino. They were surprised it punched above its weight — it was comparable to binos 3x its price.

It has everything the Forrester Gen II HD has, plus ED lens — unheard of in this price range.

One seller — the same seller I bought the Leaysoo bino from — had it at 555 yuan (US$76). I hesitated for a while — do I really need another bino — but I still bought it. Unfortunately, he told me to cancel my order as it was out-of-stock.

I found another seller listing it at 574 yuan (S$106.60). Other sellers list it at 730+ yuan, matching its MSRP, so it could be a pricing anomaly or there was a price increase and this seller did not get the memo.

The seller told me it was out-of-stock, it would take a week for stock to arrive. No problem, I can wait.

Interestingly, it is smaller and lighter than the Forrester Gen II HD bino.

Comparing it against Forrester:

  • Sharper in center, easier to focus
  • Slightly brighter, can see more clearly in low-light
  • FoV is marginally bigger only
  • No less color fringing! Shouldn't ED lens eliminate it?

I googled "sv202 color fringing" and found someone's feedback:

  • FoV is 0.2° narrower than spec — no wonder
  • Off-axis CA (Chromatic Abberation)
  • Strong pincushion distortion

It looks like the ED lens is not really working. A true ED lens will eliminate color fringing. Well, you get what you paid for.

Svbony SV202 bino is also available as Shuntu's (胜途) 小钢炮 series.

And now that I know better, I'm going to look for:

  • ED lens
  • Angular FoV 8.1°
  • Flat field

I'm not planning to get one any time soon, though.

The perfect wildfire

From Elon Musk:

Incompetence, in the limit, is indistinguishable from sabotage

Strong wind. Dry weather. Uncleared vegetation. No water.

Two of them are man-made.

The cause is not important — wildfires happen all the time. What is important is why the fire failed to be contained.

Hawker food must be cheap, period

News: Singaporeans’ reluctance to pay more for hawker food is endangering the trade

Date: 6 Jan 2025. Source: CNA.

Is it reasonable to say that everyday Singaporeans rely on hawker food, hence it ought to be cheap amid high costs of living?

In recent years, the financial sustainability of Singapore’s hawker trade has become a pressing concern. Hawkers face numerous challenges, chief among them being rising costs of manpower and raw materials.

Some hawkers report operating costs exceeding S$10,000 per month. Yet, the public’s expectation for affordable food options forces them to operate with extremely thin profit margins, sometimes as low as 20 to 30 cents per bowl.

Hawker food, like public transport, are at the bottom of the "food" chain. They have direct impact on the cost of living.

That's why their prices should be kept low. Increase them, cost of living goes up, the effect cascades across the entire "food" chain, causing another round of price pressure.

Being a hawker is hard work. It comes with the job description. But to say hard work allows food to command high price? No.

Is rent really as low as stated? NEA always says it is low (citing median rent across all hawker centres), but anecdotal accounts always suggest otherwise — especially for non-NEA managed places.

And then there are "upscaled" hawker food. These should really be cafes, but of course they can't afford to rent a place. They can exist, but they should be minority — no more than 20%.
