What do you mean never seen?

On HF, click on any Q2K quantized model in GGUF format, it will show the metadata. Look at the expansion of the blocks. You will a mix of quantizations.

Dude, your comment does not compute.

Care to clarify with actual math? We are a technical audience here.

kanbankaren··on I didn't know I was lacking in Vitamin D until I collapsed at work
Just take Vitamin D3 supplements. They are cheap like 5 cents for 1000 IU and it is highly bio-available. The supplements have been used for literally decades.

Getting it from mushrooms becomes expensive and quite a chore.

kanbankaren··on I didn't know I was lacking in Vitamin D until I collapsed at work
Yeah, I remember these studies.

I am not sure whether they compensated for BMI or used sufficient dosage. A 2000 IU/day might not be sufficient as the amount required depends on the current level and BMI.

From studies we know, Vitamin D accumulates in fat cells before it is available for bodily functions, so unless the dosage was adjusted for BMI, the experiment might not have been done on an equal footing for all participants.

How do we know that Vitamin D accumulates in fat cells? When someone loses weight, the Vitamin D level improves dramatically despite not having ingested any Vitamin D or made from sunlight.

> I've got to wonder about correlation vs causation.

Link between Vitamin D and depression has been known for a long time. It is not a new finding.

> your body naturally produces Vitamin D as a reaction to sunlight (being outdoors), and not having sufficient time outdoors, especially in a pleasant/nature environment, may be contributing to depression.

At higher latitudes, it is extremely difficult to produce Vitamin D from sunlight unless you expose your entire torso(without a shirt). If you have dark skin, you need 2x or 3x more time.

Again, there is extensive literature on this, you just have to read it instead of speculating.

kanbankaren··on I didn't know I was lacking in Vitamin D until I collapsed at work
There have been several studies linking low Vitamin D levels to depression. A meta analysis found improvement when supplements were taken.

I forgot about this post.

Based on rendering quality even at low PPI, it is IBM Plex Mono though I would pickup the open source variant Blex Mono Nerd Font as it adds icons too.

If you are worried about privacy, do a FDE, but don't enroll with TPM.

You have no idea what is inside the TPM chip and its vulnerabilities.

Actually, I hate it. zero is not crossed, right?

Fonts from Google have been bland and monotonous. The only nice font that Google released is Spectral(from France), but it is a proportional serif font.

kanbankaren··on A Modern Web App in C
As someone who works on C compilers, I find the obession with C language insane.

For any greenfield project, pick up C++ in lieu of C if you want a C language.

There is no runtime penalty for using C++ if you stick to plain structs and don't use virtual functions, but you get better static type safety, lvalue references, namespaces, etc. even if you don't use the OO features.

Even for virtual functions, the overhead is minimal that it is just noise.

C compilers themselves are written in C++ for the last 15 years. Oh, the irony!

Probably.

I listened to some of the voices. The male voices are believable while all the female voices sound the same and artificial. For some reason, it also reminds me of the voices in Toy Story movies.

Bias in the training data?

What is the difference between the two?

A ham operator might put out 20W of ERP while a radio station operates at 100W though international broadcasters use upto 500 kW.

kanbankaren··on Show HN: Open-source engine running Gemma 4 26B in 2 GB RAM on any M-series Mac
Yes. Model would be limited in its performance, but it would perform well in the limited domain because LLM interpolate from training data. They don't think like humans.

We might think that knowledge from logc and discrete math would spill over to coding. Unfortunately, it doesn't seem to work like that. Even 1T parameter LLM fail on tasks if there are no variants of it in the training data.

> Always curious when someone will figure out how we can elide most of the data from an LLM (but retain the logical ability). I don't actually need an LLM to have a very big internal knowledge base to be useful, so long as it can invoke a search tool...

I think this can be achieved already. Take a base model and train only on source code. In fact, the very early Granite models from IBM were like that though it didn't support reasoning which limited its performance.

You can do it too. I don't know how much it will cost to train on just source code repos. $10K in total? Not sure.

What a ridiculous comment!

Cellphone emergency broadcasts turned out to be not reliable during the Hawaiian Island fires.

RDS in FM has a special mode for emergency broadcasts and some countries use them. As FM signals easily cover a 50-75 mile radius, the coverage area is huge versus cellular emergency broadcasts requiring the towers to be powered on which have also failed during natural disasters.

kanbankaren··on It's a shame what's happened to radio
Hey,

I can receive RNZ on shortwave on the East Coast of USA! About 10,000 miles away if we count the signal bouncing multiple times between the ionosphere and the ground.

kanbankaren··on It's a shame what's happened to radio
My current Android phone has a FM radio that doesn't even require a wired headphone as the FM antenna is built-in. If you connect your BT headset, the FM station is heard through the BT headset in full stereo.

Of course, it is a Chinese brand who haven't forsaken FM radios. Apparently, Europeans still prefer a FM radio on their smartphones that Chinese brands that sell in Europe still retain them.

Here in USA, people don't seem to care about radio.

Don't be smartass. My question was how to change pitch? Most people can't change their pitch unless they have been trained. I can't speak with the pitch of child or woman. Neither are most people.

How would you pitch-up?

Does the entire Japanese population learn these things while growing up?

kanbankaren··on Reading the news is the new smoking
You drank the kool aid.

Even for USA,

1. The 90s were the most violent period in terms of crime.

2. Corruption has neither increased or decreased in the last decade.

3. Other than the 2020 election during the pandemic, the number of votes cast has increased in every election contrary to your claim.

kanbankaren··on Reading the news is the new smoking
> we’re still in the situation of today.

What situation are you talking about?

The world is less violent, more affluent than 30 years ago, but appears to be the opposite due to 24/7 news cycle.

kanbankaren··on Elastic lays off 7% of employees
> I also think that concepts like debt to GDP ratio are somewhat detached from corporate policies.

Corporate policies ultimately decide growth. More growth leads to higher profits and higher tax collected by the Government which in turn means they don't have to borrow more.

kanbankaren··on Elastic lays off 7% of employees
> many parts of the Japanese system of hiring for life

This is a terrible strategy. It encourages inefficiency to metastasize throughout the company.

No wonder Japan is stuck in a rut since the 90s and its debt-to-GDP ratio is 205% which is one of the highest in the world.

Your romantic idea of Japan would get destroyed by just browsing www.reddit.com/r/japanlife/

Japan has one of the worst work culture and low productivity in the world.

kanbankaren··on I replaced Spotify with a homemade FM radio station
Terrible in one word.

The bandwidth for AM transmissions in North America is only 20 kHz and radio emissions has to STRICTLY fall within that bandwidth. Technically, it allows an audio BW of 10 kHz, but in practice it is close to 4 kHz which is telephone quality.

Not suitable for Music.

You drank the aptX kool aid and forgot the fidelity loss along the signal path.

FM broadcasts do a high pass at 50 Hz and stop at 15 kHz. The best SNR is only ~50 dB which is already achieved by plain old SBC. There is no need for higher fidelity audio codecs like AAC/aptX/aptX HD/LDAC besides the fact that most smartphones don't support aptX or aptX HD.
