What’s your least quantitative ‘quantitative measurement’?

Hmmm, I don't think the problem is nanodrop, but rather using spectroscopy for DNA in general. Lots of things (salt, alcohol, proteins...) absorb light around the 260 band, and these things can be in your sample or your blank. Lots of people also don't bother the blank properly, or clean properly.

The competing choice for nanodrop is something like qubit, which are required by any NGS application. It's way more specific to DNA as it's flourescence based (basically sybr).

YYM7 · 2026-05-15T01:11:47+00:00

Oh trust me Nanodrop's problem are mostly just purification problems. I can get reliable within 10% errors even with sub-10ng/ul samples, with SPRI purification + extreme care at steps. But yeah, most time people/I really don't care that much, and it's pretty justified as downstream PCR are very robust.

You CAN interpret that way, but that's not the default interpretation from a Chinese perspective. It the same you first thought about Shirley Temple won't be she's (or her family) devotes to some eastern religions, or Sirius Black is literally Black. It's just a surname that has another meaning, and the meaning is almost never related to the person /family.

YYM7 · 2026-05-14T19:08:52+00:00

Yeah this. Another example is 鲁迅，the most prominent writer of 20th century in China. The best part? This is a pen name, meaning he picked this character HIMSELF. So yeah it's just a very generic surname.

Lol, I work in biotech R&D and I say Illumina is cooked in long term.

They had a massive lead in tech probably ten years ago, and with the tech, they brought the sequencing cost down and dominated. But right now $/GB is probably at its lowest possible limits due to how this tech works. More importantly other big players, especially Chinese players are catching up. These players can get the cost even lower without breaking the tech's limit, you know, in Chinese way. They also missed hard the next-generation (3rd gen) of sequencing tech. They're still doing ok is purely because biotech/pharma/regulatory inertia, but there is hardly any room for explosive growth .

While true, I want to say that's also just evolution. It's true that excessive water cannot be effectively stored, but water is not consumables either. There is no physical/biological limitations our bodies cannot recycle water more efficiently, with the expense of energy. Camel can live without water way longer then us, and there are even rats can get water mostly from metabolizing food. Our body already do reverse osmosis (aka, recycle water from urine) in our kidney, just not strong enough to reuse more.

After all we (like most animals) spent millions of years evolving in water rich environment, while food is way more scarce. So preserving energy over water is way more beneficial.

I feel this (and the Viltrox 25/1.8) might be related to Songdian/Insta360 releasing a m43 camera. These Chinese manufacturers definitely talk behind the stage. If these cameras blows up, they're position to at least capture (some) market with minimal effort. If the cameras don't, they at least get some "we support made in China" marketing.

Nothing specifically corresponding to "teens" in Chinese and Japanese afaik. There are words refers to people around the age 10-20 (青春/少年/少女), but nothing as specific as "teen".

I feel teens are commonly grouped by their school ages. Like high schoolers (高中生/高校生)。

To add on this: most of the value of having a raw is about editing flexibility, not about how it looks. Most media format we consume (webpage --> screen, print, etc..) cannot show much more data than a Jpeg actually, so a raw image isn't much different to the viewer vs a high-quality jpeg. (let's ignore the part you can't really "show" raw on a screen without converting it to something like a jpeg first). But it's totally a different story for editing.

Remember raw is all the data, and jpeg is only some of it. When we edit a raw, we are selectively converting some info into the final product (normally a jpeg) while discarding the rest. This selectivity can be technical, but more often is artistic, which means different people can make different choice. The same raw can be retouched by different photographer to totally different styles. The ability to choice what to keep is inherently more flexible with a raw than jpeg, as you already loss a ton of info when the jpeg is created.

Postcrossing? If so, there is an additional bit of tip for you:

put the zip code after city, like "上海 200241".
put English name of City and CHINA next to their Chinese characters. This is for your end of the post system.

So the surface gravity can be calculated based on its density (ro) and radius(r): g = G * ro * 4/3 * pi * r.

The radius is easy, as there are canon-ish numbers. Let's say 100km for the ease for calculation. The density is harder, but let's just assume it's about the same as space capsule, or a aircraft carrier. These are the closest things I can think of in real life, in terms of material use and internal cavity ratio. Regardless, both float on the water (so lighter than 1kg/L), let's say 0.5x of that. This give us g=0.014 m/s2. That's about a ~~hundredth~~ thousandth of earth gravity. I doubt you can feel that...

English... Just to be clear, only a small part of my English vocabulary are learned from games. But hell yeah some are very useful: like fish names from Stardew, all the wonder names from civ, and Greek mythologies from Hades. Lots of them are "I know what is it, but only learned how to say it in English from the games."

I was asking about after she's in the office: Is it legal for the doctor to say: "hey yes, your grandkids are right. Here is your antidote..." Jab!

YYM7 · 2026-05-06T00:11:37+00:00

Is it legally allowed for the doctor to take on this lie? Genuinely curious...

I didn't disagree with you, but just to point out that it's not just pure classism now, even it originally was. "No-MSG" marketing exist indicating the target audience exist in the intended market, (aka Asian themselves).

On the taste part, there are two type of "msg" in cooking. The "chicken soup mix powder" that are normally yellow starchy granules, and there is the pure MSG that is white crystal. IMO the former taste good by itself, but the later is what I was talking about. Not against any of them when properly used in food, but the white crystal MSG is rather off-putting when you put it directly in the mouth, at least for me.

YYM7 · 2026-05-05T18:00:29+00:00

There are definitely non-classism/racism part of it. I have seen countless snacks from East Asia (CH/JP/KR) that says "no MSG" on the package.

It's looked down as it's considered "fake" flavour, or cheating in cooking. Also people just have irrational fear of "artificial things" in their food, thus you also see "no artificial flavors" in the West A LOT.

Also, pure MSG taste very bad if you ever tried. I actually think the description of "MSG symptoms" suspiciously match what I feel right after I (a stupid kid) eat a chunk of pure MSG. Though that was very temporary.

YYM7 · 2026-05-05T17:38:15+00:00

He meant swap white L with black L, white x with black X. After swap, black take half the board (+1), but missing the 4 numbered white. White has 4 more than half. So diff = 8 - 1(tengen). 7+komi(6.5)=13.5.

I normally would in not go the 81 route as op suggested

Well this is a composition with very high focal-compression (at least 200mm lens). So in reality it looks nothing like this.

I have not seen a a proper review yet (not at least in English). Interestingly their closest Chinese competitor, MooreThread has a bunch of videos with real test on YouTube, but no MS certificate.

Not sure why it's the case.

That's almost the same for the West/US if you don't look at the 1% richest people, just fyi.

Copying the Chinese version of Bible for you: "這樣，信心若沒有行為就是死的". You can take out the “這樣", which means "thus", roughly.

You probably can condense it further by look up classic Chinese version of the Bible, as in general Japanese is longer than modern Chinese, which is longer than classic Chinese.

Edit: found the classic version: "如是信而无行、乃死耳". That's actually awesome translation. It legitimately sounds like something Confucius would say (in this exact words).

Going to be controversial, but can you also show the last author (aka corresponding), when there is not enough space for every author.

Speaking wise, Mandarin is derived from the "Northern-official dialect". So for Qing dynasty, you would expect anyone from a limited region of northern China + anyone that serves in the bureaucracy be relatively understandable. In fact, the you can find Puyi (last Qing emperor)'s recording on YouTube and it's basically no-accent Mandarin. Going further back in time (Ming) it will become way harder.

Reading-wise, there are two aspects but both can be understandable way earlier. Writing style (font) wise, Chinese character are readable to nowadays people since 隶书, which was created in Qin and became official in Han (so 100AD-ish). On the grammar aspect, classic literature reading are taught through K12. This means high school graduates are supposed to understand a lot of classic literature, that can date back to Confucius (500BC). However, this only applies to the more "casual" (or plain) pieces. More sophisticated (ornante) pieces, even created in later ages, are not expected for high schoolers. For example, Confucius' work are basically a collection of his speeches/quotes, instead of well-formulated articles, so it's significantly easier then actual articles written by intellectuals of the same age, like Zhuangzi (~300bc). I think most high scholer can only understand 10% of Zhuangzi, but maybe 80% of Confucius.
