sifar··on Tech companies are firing everyone to "fund AI", spending money on each other
Curious, how do you deal with hallucinations for important stuff ?
sifar··on What happened to running what you wanted on your own machine?
Curious, have run GrapheneOS on pixels ? They don't have this issue, though it might change now.
sifar··on Americans can't afford their cars any more and Wall Street is worried
I think what they mean to imply is that banks create new money out of thin air and the actual value of the assets would be lower if these new loans were curtailed.
sifar··on LoRA Without Regret
And I thought you were going to say thinking machines :). Buy yeah LoRA trips me up too.
sifar··on For all that's holy, can you just leverage the web, please?
Try the Spectre TVs. They are normal oled TVS, not smart. Been using one for a few years now, am very glad they exist.
sifar··on Why teach calculus in the age of AI
However, we don't know beforehand, which of those people would produce new knowledge.
sifar··on Australia Post halts transit shipping to US as 'chaotic' tariff deadline looms
>> And as much you want to tout IT services, overall GDP contribution is 11.47% and pharma is 1.72%. Someone has told me that the remittances from India to US is 3%. All that combines to less than 19% contributed by agriculture.

That is the direct GDP contribution of IT/allied services. The indirect societal contribution is significant. Most real estate in big cities, transportation, food and other services rely on the IT industry. Expect a lot of pain in India when this is impacted.

sifar··on Pixel 10 Phones
My 4a didn't have the battery issue due to GrapheneOS, however, it the screen died recently (twice), so I got a pixel 9 with GrapheneOS. But yeah, it is uncomfortable to use the phone with one hand - I miss the small sized 4a.

On the other hand, it would be fun to explore these on device SLMs on a more capable phone with extra ram/storage.

sifar··on The "high-level CPU" challenge (2008)
Really curious about why you think programming a vector machine is so painful ? In terms of what ? And what do you exactly mean by a "true Vector Machine" ?

My experience with RVV (i am aware of vector architecture history, just using it as an example)so far indicates that while it is not the greatest thing, it is not that bad either. You play with what you have!!

Yes, compared to regular SIMD, it is a step up in complexity but nothing a competent SIMD programmer cannot reorient to. Designing a performant hardware cpu is another matter though - lot of (micro)architectural choices and tradeoffs that can impact performance significantly.

sifar··on Meta's Vision for Superintelligence
>> an even more meaningful impact on our lives will likely come from everyone having a personal superintelligence that helps you achieve your goals, create what you want to see in the world, experience any adventure, be a better friend to those you care about, and grow to become the person you aspire to be.

What has intelligence (let alone superintelligence) or lack of, got to do with the last two. All these discussions about AGI seems to have reduced what it means to be a human being to a token generator.

sifar··on Studio Ghibli marks 40 years, but future looks uncertain
In Passing - Lisel Mueller

How swiftly the strained honey of afternoon light flows into darkness

and the closed bud shrugs off its special mystery in order to break into blossom

as if what exists, exists so that it can be lost and become precious

sifar··on For Some Recent Graduates, the A.I. Job Apocalypse May Already Be Here
>> To me, embracing the tools and becoming an prompting expert is the way to go, rather than some Luddite-like rejection of the technology because of some offended artistic notions

Your first part may be right, however using the term Luddite as a pejorative without understanding what they meant or stood for (given the social context) is a sign of ignorance.

sifar··on Thoughts on thinking
>> Focusing on the action, not the target is what relieves one of the disappointment of outcome.

The primary reason is not that it relieves us of the disappointment, but that worrying about the outcome increases our anxiety and impacts our action which hampers the outcome.

sifar··on CarPlay Ultra, the next generation of CarPlay, begins rolling out today
unless one uses a phone that cannot connect using Carplay/AA. (grapheneos on pixel)

Like the sibling comment said, I should be able to choose to be able to pair my phone with my car.

sifar··on Anti-Personnel Computing (2023)
I was discussing this with my son the other day. We have a Faustian bargain with technology in general, not just computing.
sifar··on OpenAI Says It's "Over" If It Can't Steal All Your Copyrighted Work
>>Nature is a complex system.

There is no winner take all in an ecosystem. If it happens, that ecosystem collapses !!

It is strange that you use this as an example yet fail to understand it fully.

Nature is a complex system ... with adaptive feedback. Every process is a cycle - has feedbacks that amplifies/regulates it. Yes there are apex predators, but there is no winner take all in an ecosystem. Living beings coexist.

sifar··on How one of the world’s major money laundering networks operates
>> The way I see it, cash right now basically only exists so that small businesses/individuals can cheat on taxes and to keep criminals on the USD.

sigh Cash is the barrier for interest rates going negative for too long. sigh

sifar··on Curtis Yarvin Says Democracy Is Done. Powerful Conservatives Are Listening
>> While I strongly disagree with them, I feel an affinity and familiarity with their thinking. I have read the same books, seen the same news, and lived in the same era. I understand how they arrived where they are now.

Similar , however I see them more as extreme greed (for power/control) and technological hubris.

Interesting how people interpret things differently based on their life experiences. I feel this is what strong advocates of objective facts and EMH tend to miss. People have the same input data, however the interpretations are different based on the (hidden) internal state.

I keep wondering, what does the richest man in the world want more ? Why this ? I find it a very revolting way to live.

sifar··on Curtis Yarvin Says Democracy Is Done. Powerful Conservatives Are Listening
>> Having the ability to do more, on a bigger scale.

Even waste , inefficiencies ? That is setting yourself up for a big collapse too. One needs to look at it from a more resilient, sustainable perspective, like a biological system.

sifar··on Karatsuba Matrix Multiplication and Its Efficient Hardware Implementations
One can use this techniques to optimize the multiplier inside the FP FMA unit. However this cannot be used to multiply two floating point numbers as FP arithmetic is not associative.
sifar··on Karatsuba Matrix Multiplication and Its Efficient Hardware Implementations
I have used Karatsuba's & Winograd's Inner product [0] algorithm in my work for wide multi-simd integer multipliers and matrix multiplication HW for DSPs. The latter cuts down the MACs by half - n^3/2 instead of n^3. I think the paper talks about it's derivative - FFIP.

The issue is memory bandwidth. These techniques indeed help you save multiplier area however the performance is still bandwidth limited - you'd need to be able to feed more data per cycle to increase performance.

One thing the paper doesn't talk about is energy. For DNN, at the network level the energy consumed by integer macs is not that high. Localizing data computation would have a much more impact on energy reduction than optimizing MACs.

sifar··on Stoicism's appeal to the rich and powerful (2019)
>> Behind each of the stoic virutues is a psychological position to dettach, dissociate and live in a more abstracted conceptual space.

You and I have a very different understanding of stoicism. Stoicism's concept of attachment is much more closer to a Daoist/Buddhist one. They don't advocate renouncing the world in fact the opposite - how to live fully. Just that don't cling to things - especially the results as a lot of factors that affect it are not under our control and when things don't happen the way we were forcing them to happen, resentment and anger follows. This can be applied to work, relationship, parenting. It is quite practical.

It is fascinating that these two different cultures developed similar philosophies around the same time in history.

One needs to let go of the medieval/modern interpretation of stoicism which creates such resentment and approach it from a more eastern perspective.

sifar··on Cursor told me I should learn coding instead of asking it to generate it
>> that's progress, not a problem.

It's a tradeoff. What we call progress is actually a tradeoff for what we value and prioritize more. It necessarily doesn't have to be good - just a state of the world we create.

sifar··on Intel appoints Lip-Bu Tan as its CEO
>> If you can slim the processes, a.k.a reduce bureaucracy, then a ton of people can be let go. Also if you let go a ton of people, processes are forced to become more efficient.

Or broken. The latter has a higher a probability.

This is pretty naive, one dimensional thinking. Making things efficient requires deep systems understanding and lack of which is on display here (Chesterton's fence). And one can achieve it reasonably for physical/technical things, however dismantling social processes that have evolved over the years for variety of reasons indicates neither the capability nor the desire to improve them.

sifar··on Real Chilling Effects
How about we re-frame it as would you rather have one person or a group of people to destroy a city or the entire planet and intelligent life on it? Would you rather be able to enslave a particular region or the entire world ?

You see, we are trading improvements in some aspects to that of another.

The thing is you cannot separate the benefits these technological advancements bring with the problems they create. The rate of technological change is much more rapid than our ability as a society to adapt to it. This is one of the source of friction as the negative effect become real only later.

There is no physical law that says technology has to improve - it is our quest, or drive to seek it, we choose it, every time. And I say this as someone who is part of this.

sifar··on The Pentium contains a complicated circuit to multiply by three
If you are negating a single term you can't.

If you are adding n terms using an adder tree, the 1 feeds to the carry in of the next level ( it is simply a concatenation since the carry term is shifted left by 1). Only thw final carry propagate adder will have the add with 1.

sifar··on The Pentium contains a complicated circuit to multiply by three
Sure it takes a few iterations, but there is nothing inherently complex about it.

You feed the partial products into a carry-save adder tree and choose a level which minimizes the delay and the extra flop area/power. I am not sure about the pentium technology but whatever the area, it might be comparable to the x3 multiplier

There is an implicit add in the x3 multiplier circuit that increases the delay which was deemed acceptable than the radix-4 delay. Considering all this, I strongly believe latency was a hard constraint (may be for SW perf).

sifar··on The Pentium contains a complicated circuit to multiply by three
Interesting choice of radix-8 booth multiplier that needs the x3 circuit. Seems like a area/perf tradeoff in order to push the fmax which means they had a latency cycles constraint since the same could be achieved via more pipelining.
sifar··on Hot take: GPT 4.5 is a nothing burger
Moore's Law is a self-fulfilling prophecy derived from the value of computation. If a given computation does not provide enough value, it might not be invested with enough resources to benefit from Moore's Law.

When scaling saturates, less computationally expensive models would benefit more.
