Nydhal··on Show HN: The operating system I built as my high school project (2016)
Kannada? I'm not indian but I remember these symbols from a twitter crawling project.
Nydhal··on SQLite as an Application File Format (2014)
You can open a SQLite file as text and read it and be able to discern data and tables.

Not saying it's useful but you saying "only way to read SQLite is SQLite" is hyperbole.

Nydhal··on Movim – Federated, open-source alternative to Tumblr
facebook was a mistake.
Nydhal··on A New History of Arabia, Written in Stone
If you are interested in this subject I highly recommend following Ahmad on twitter where he is very active.

Nydhal··on Ask HN: Is it worth getting into distributed systems after 12 years full stack?
Until no one actually owns phones and all you have are shared shells that can be picked up anywhere.
Nydhal··on Future of Statistical Programming
I disagree that scripting XOR point-and-click. Why can't we manipulate a dataframe using both approaches?
Nydhal··on Ask HN: Why did your startup fail and what did you learn?
> I could have been SalesForce if I hadn't been arrogant.

Did you overcome that and learn from the mistakes? No offence, but to be honest you saying "I could have been SalesForce" makes it seem like you're still working on the arrogance part.

Nydhal··on New Electric Drone Has Groundbreaking Flight Time
While true, groundbreaking should usually mean "order(s) of magnitude" improvement.

It would have been more adequate if, say, the drone could last a day. Which would roughly be a 10x improvement.

Nydhal··on Driverless Hype Collides with Merciless Reality
I'm sorry I can't back up my claims but you will be proved wrong with time.

I would bet in less than 10 years you'll have camera only fully autonomous systems.

Nydhal··on Timeline of the far future
on an exponential scale 10000 years is just one step ahead.
Nydhal··on Through-Wall Human Pose Estimation Using Radio Signals
"Available for me". Are you assuming we know who you are? What's available for you might be very out of reach to others. Farady cages are not some wallpaper you put on your house.
Nydhal··on Elon Musk’s Boring Co. Wins Chicago Airport High-Speed Train Bid
How valuable is the Boring machine and how valuable are the tunnels? What's the quantitative measure you're using?
Nydhal··on Are My Friends Really My Friends?
Doesn't work. Simply because of nth order effects. This type of reductionist approach cannot be plugged-in by design. Simple solutions grow out of complicated ones following some evolution not the other way around. The proof is they kept moving the number upwards.
Nydhal··on All images of the Facebook ads Russians purchased during the election
This is an indicator of a large scale operation. Scaling an operation entails a degree of tolerance to the degradation in the quality of the product, especially when the marginal benefit from quantity significantly exceeds that of quality.

Cyber space is a high leverage domain which rules out the possibility of a shortage in resources from the opponent. It is also a recent evolving space which makes it more difficult to assess the opponents capabilities, reach and sophistication.

By its nature this operation seems to be part of a bigger destabilisation strategy, maybe a stress test to validate different tactics.

I would be really worried once the ads become well written which would increase the complexity of the situation since quality measures can be manipulated.

In other words once they can fake "fake news", things might get really weird.

> militarizing the police

That's where the right-left model breaks. This is not an extreme right wing thing, it's statist authoritarianism. Can be embraced by both sides, extreme or not.

Nydhal··on Microsoft makes AI training courses available to the public
Mostly Microsoft's. I assume some Azure from my previous experience with on of their courses.
Nydhal··on Lessons from Optics, the Other Deep Learning
A step in the right direction would be to encourage sharing negative results. It's important to know what to avoid too.
Nydhal··on India has a hole where its middle class should be
Yes. In my country we don't have any of the american fast food. I guarantee you if Mcdonalds opens shop there same thing would happen. HN readers seem to be very unaware of how different lifestyle/culture is across the developing world.
Nydhal··on Neural Style Transfer for Musical Melodies
In one word: locality. Images have it narratives do not.
Nydhal··on Goldman Sachs Is Setting Up a Cryptocurrency Trading Desk
Most transactions fall into the first -solved- category, a minority is in the second.
Nydhal··on Fundamentals of Linear Algebra and Optimization [pdf]
You had me at Bourbaki.
Nydhal··on Machine Learning for Systems and Systems for Machine Learning [pdf]
It could be. CS and more generally tech related fields have this positive feedback loop where the technology facilitates it's own development.

For example:

The easiest and most abundant thing to learn on the web is unsurprisingly web development.

An ML engineer can use ML to optimize the data structures that he uses for his models.

I could not say the same about fields like biology or physics.

Nydhal··on Machine Learning for Systems and Systems for Machine Learning [pdf]
I thought it was a stretch when reading that medium post. Now reading this and thinking about it after finishing two undergraduate classes one on operating systems and another on compilers, the machine learning for systems part makes a lot of sense, apart from the heuristics the learned index structures idea is just fascinating.

Another illuminating sentence from the paper was this:

>This leads to an interesting observation: a model which predicts the position given a key inside a sorted array effectively approximates the cumulative distribution function (CDF). We can model the CDF of the data to predict the position as: p = F(Key) ∗ N

Maybe it's just my very limited knowledge as an undergrad but I'm feeling that this can be the start of something big. Another idea that just came to me after is how much of this ML is applicable to the domain of cryptography. In my security class it seemed like much of the famous hash functions for example were somehow "found" in vast space of potential schemes.

Nydhal··on Facebook wants your children's mind
Live very far away from parents, family and friends. They don't use other options. Not worth it to convince them all to switch.
Nydhal··on Project Euler
Euler was a mathematician after all. Now thinking about it I wonder what project Djikstra would look like, or say maybe project Stallman.
Nydhal··on Steam is no longer supporting Bitcoin
You should increase the bet with every interval, for a better outcome :)
Nydhal··on Taking Children Seriously
You have a very naive idealistic view of the world. A lot of bad things HAVE come out of such views of the world.

Nydhal··on America’s flat-Earth movement appears to be growing
I have this crazy theory (just for fun) that flat-earthers are people who want to be taken to space, as in they fake the disbelief in order to advance space exploration. If I bet you $1000 that the earth is flat you'd have an incentive to prove me wrong, the easiest way is to make going to space for me to observe the earth from a distance as cheap as possible. In this age of outrage it is easier to get people interested in a subject by spurring controversy than it is by igniting their curiosity.
Nydhal··on Drinking 3-4 Cups of Coffee Is “More Likely to Benefit Health Than to Harm It”
In some sense traditional medicine or traditional\religious healthy habits (I'm thinking something like kashrut) has way larger sample since it's been practiced for millenia and its populations still survived enough to transmit them to offspring. If grandma made it long enough to teach the grand kids some old traditions there's probably some merit to some of them.
