sufiyanon Computer scientists invent an efficient new way to count

Let’s prove it by contradiction: Lets say you pick the larger ones and drop the smaller ones every single round, you have lost the probabilistic guarantee of 1/2^k that the authors show because the most frequent words will be the lost frequent in subsequent rounds as well. This is the intuition, the math might be more illuminating.

sufiyanon Intel prepares for $100B spending spree across four US states

Although I am rooting for Intel, the leadership is just not an execution machine. Pat is a very good CEO, and he understands technology as much as the business. But the next level simply doesn’t have that charisma to deliver. I wouldn’t be surprised to see many delays and eventually a product which is years behind competition.

sufiyanon Toward the Decipherment of Harappan (2022)

Exactly. Considering that Brahui is a Dravidian language, I always wondered how can regions so disjointed (Pakistan and South India separated by at least a few thousands of kilometres) have a common origin.

sufiyanon Immune cells fighting cancer get exhausted within hours of encountering tumors

Is there some way to induce a cytokine storm of sorts so that this weakening is essentially reduced

sufiyanon The microarchitectures that I saw and the ones that I hope to one day see [pdf]

I don’t get it. If security is so important, then it should be okay to sacrifice performance. Why is there such inertia in accepting this? If security is all that is needed, get an in order completely non speculative core with no branch prediction (you can’t even run your side channels in this case efficiently)

sufiyanon Dominion Voting Systems and Fox reach last-minute settlement

Wow the guys in the newsroom didn’t believe what they were saying and still said it. If there was a word for journalistic non-integrity, I’m searching for it now.

sufiyanon Ask HN: How do I start feeling secure financially as a tech worker?

Get a higher paying job. While that is harder said than done, the process of preparing for such a job search, could keep you prepared for the worst should it come.

sufiyanon Apple AMX instruction set (M1/M2 matrix coprocessor)

I don’t get why other chip manufacturers don’t go this same route. For example AVX is done on the same core that also supports integer math. Many companies have a separate GPU but AVX seems to always come prepackaged.

This was the case when Google launched their TPU as well. Look where they are now

sufiyanon I tricked myself into working out 3 times per week

I have always found myself more engrossed and wanting to run if I have a great podcast series or a great audiobook to listen to. Lately haven’t been getting any good recommendations and feeling like it is a chore to run.

Maybe having a bet like this with my sister who is also trying to become more active might help.

sufiyanon Ask HN: Which parental action increased your happiness and success as an adult?

My parents would talk about their struggles growing up without any money.

My mother who was orphaned at a very young age and was raised by her grand mother would tell us about how she would have to erase their books and turn over their school uniforms and restitch them when they got faded when a new school year began because they couldn’t afford new clothes or books. My uncle who was all of 8 months when my grand parents passed away, had to struggle to make his school fees. Yet they have done well simply because of their perseverance and hard work. When I think about it, luck must have played a role but they still worked very hard to make their lives and their kids lives better.

My father would tell me about the time when they couldn’t afford to buy milk for me as a kid. And his cousin who was many years his senior asked him if he had any savings and when they answered in the negative, implored him to start.

These 2 things have always been my guiding lights. Very recently I have started losing interest in everything that is happening around me due to life circumstances. And writing these things has truly helped me understand where I’m from and what I need to do. Thank you OP

sufiyanon The sky-high cost of returning to the office

As someone from India, this is far more acceptable than the alternative. Folks around my age just got married before or during the pandemic and as most of us had moved back home (people travel to Bangalore to work although there are decent options in other places). However the strife that I see on a regular basis between my wife and my mother is itself enough to want me to leave and just get back to work. Add a kid to this and it is just a circus at home. I’m sure although I’ll spend a lot on relocating, it is worth it for the simple reason that it is lesser mental tension to keep people away from each other.

sufiyanon Why is houseplant advice so bad?

Yes you are right in that I have a dedicated place for them.

You could try using water sprays instead.

sufiyanon Why is houseplant advice so bad?

Something I learned to do is to only water the leaves (ie make them wet). And if the soil is very dry, to pour water directly to the roots.

My reasoning being that rain unless it is heavy, doesn't actually reach the soil directly and then there is the matter of water coming out through the openings in the pot if there is too much of it.

I don't know why this works for me.

sufiyanon 20K Workers Will Be Jobless in Indian IT Sector, Thanks to Infosys and Cognizant

The Indian government gives them contracts. A lot of big Indian companies also get droves of them to do repetitive work with no visible path of career progression

sufiyanon 20K Workers Will Be Jobless in Indian IT Sector, Thanks to Infosys and Cognizant

Nah.. That's how much they get paid. The consulting company will charge about 5-10x for this resource though. (source from a friend who was there)

sufiyanon AMD is having its day

You really need to look a little more at Jim and his style. He has been around from the time of DEC (Digital Equipment Corporation). And has been a great engineer. But what sets him apart is not his technical competence, but his ability to organise great teams around him and get the work done. And he has always been the person who has been given the reins of companies in crisis. It is a marvel how he manages to get the product back up.

sufiyanon Ask HN: Who is hiring? (November 2019)

So, there are 2 teams. 1 is in traditional computer architecture (OoO, Branch prediction, memory, prefetchers etc) and the other is in AI/ML accelerators. If you have AI/ML software engineering experience, I would encourage you to apply for the AI/ ML team.

sufiyanon Ask HN: Who is hiring? (November 2019)

Intel Labs | Architecture Research Scientist | Bangalore, India | ONSITE | FULL TIME

The Processor Architecture Research (PAR) Lab leads research into futuristic high-performance and highly-secure CPUs to extend Intel’s general purpose compute leadership deep into the next decade. We also research accelerator-based architectures for next-generation Artificial Intelligence (AI) based on compute-in-memory and compute-near-memory principles with current and emerging memory technologies.

CPU Architecture researchers will engage in power/area/performance driven architecture research and microarchitecture development. Research Scientists working on AI will engage in algorithm exploration and software-hardware codesign to achieve best-in-class machine intelligence from the cloud to the edge.

Advanced degrees in EE/CS are required; PhD is preferred.

Interested applicants can send resume with covering letter to Sreenivas.Subramoney@Intel.com

sufiyanon Ask HN: What was your experience starting a tech consultancy?

Where do you find the good ones? Mostly LinkedIn? Reaching out on Hacker News?

sufiyanon Ask HN: What was your experience starting a tech consultancy?

Wow. Now it makes sense. When I told my first client I wanted to increase rate after finishing a basic prototype (which was the full scope of the project), he ghosted and left me a bad review on Upwork. Well, all in the game..

sufiyanon RIOT: Operating System for the Internet of Things

Having used both contiki and riot, I found contiki (NG) very good with supporting more devices and peripherals and much easier to integrate and work with. Riot is difficult in that half the times their tutorials themselves didn't work and there was no support online (this was about a year back and maybe it is better now).

I really prefer contiki ng
