Oh come on. Quick look at colorshift (13x faster): HashMap in hot loop (unoptimized Rust vibeslop) is slower than indexed arrays (ASM). No shit. Numbers like 17x should raise eyebrows but reading the comments nobody is thinking anymore. This AI psychosis has fried people's brains
I ported the Omarchy screensaver engine (ttfx) from Rust to x86-64 assembler, and it's up to 17x faster!! One-shot translation by Opus 5.5. We keep drilling until the agentic drill bit hits bedrock! github.com/omacom/ttfx/pull/…

I think MDR on UPI was probably inevitable at some point, especially given how widespread UPI adoption has become. It could also lead to more competition, instead of just three apps accounting for more than 95% of the market.
That being said, there are some use cases, like investing and broking, where the proposed MDR structure doesn’t really make sense.
The problem with broking is that there is no guarantee that money transferred to a broker will actually result in a transaction.
As brokers, we can’t force a customer to trade after transferring money. And if we can’t pass the UPI charge on to the customer, there is essentially no limit to the cost a customer can impose on a broker without generating any revenue.
Just as an example, 10,000 customers could each make 50 UPI transfers of ₹2 lakh in a month without executing a single trade. At the proposed MDR, this could potentially cost the broker around ₹2 crore, without generating any business.
What makes this even more challenging is quarterly settlement (QS). This is a SEBI regulation that requires brokers to send unused funds back to clients every month or quarter.
Most customers then transfer these funds back to their broking accounts, with more than half of these transfers happening through UPI. So regulation essentially forces this movement of money every month or quarter, and the broker could end up bearing the cost when the money comes back, without any incremental benefit or revenue.
By the way, we currently don’t charge brokerage on equity delivery trades because the economics allow us to offer them for free. But if every UPI transfer starts carrying an additional cost, irrespective of whether the customer actually trades, I don’t see how we can absorb this indefinitely.
I think having an MDR is okay. It still doesn’t solve the problem of customers transferring money without transacting, but something like 0.02% with a cap of ₹5 or ₹10 per transaction seems much more reasonable for broking, instead of a cap as high as ₹300.

Our tech team has formed a nice collective that builds and maintains open-source software for public good. The "collective" is just the latest avatar of what we've been doing from day one. Over the years, we've built and open-sourced tools that are today used by everyone from governments to large companies.
I don't think there's another company with such a small tech team (~35 people) that has shipped so many side projects that are now world-class, enterprise-grade open-source products. JP Nagar is the official FOSS capital of India 😛
Link in comments to check out all the projects.

Nothing says Open Source Leadership like shitting on volunteers that have spent decades donating their time and effort and then hijacking their work with some scripts.
What an absolute dipshit.

I find this post to be really disappointing...
It's explicitly framed as 'not a personal criticism', then goes on to include bunch of very personal criticisms about Jarred.

#RaoBahadur is truly Outrageous and Inventive! What an experience ❤️ I have heard people call it Magical Realism and Psychological but at its heart, the film is a Dark comedy, and it made me laugh quite a few times.
@urstrulyMahesh Mahesh sir platforming this is incredibly special. The big man truly knows how to back them. It takes guts from him, Namrata garu at @GMBents, my brothers Anurag & Sharat at @AplusSMovies, Srichakras and the rest of the daring producers to produce, back and release such an original work.
@ActorSatyaDev delivers the performance of a lifetime, In fact, Kudos to The excellent cast - everyone from Dr.Achari #Vikasmuppala to Acchamma #BalaParasar, to Deepa Thomas…even the lovely child actors…beautiful beautiful performances.
The artwork, cinematography, the score, even the selection of the extras is spectacular and bears Maha’s vision all over.
@mahaisnotanoun has made the most Original Telugu Film I have seen in a long time. It’s a Jackson Pollock painting with a boldness and madness that is truly unmatched. There really is nothing like it.

What Europe should do right now:
1. Call all the European researchers working on AI and return them back with same salary (or they can stay but switch career).
2. Fill EU places having GPUs with money, and put those people there.
3. AI partnerships with China + India.

Hey CBSE HQ!
Did your due diligence reveal that GLOBARENA TECHNOLOGIES and COEMPT EDU TECK are the same company?
And GLOBARENA fucked up Telangana Intermediate Board exam results causing 3 lakh+ errors and 20 student suicides?
And the CEO DGAF?
@cbseindia29 @dpradhanbjp
WTAF!
COEMPT EDU TECK and GLOBALARENA are the exact same company.
So GLOBALARENA fucked up the Telangana State Intermediate Board results in 2019 and then changed their name to COEMPT EDU TECK and the morons at CBSE HQ awarded them a contract to fuck up a nation wide exam?
ALT Previous Names | COEMPT EDU TECK PRIVATE LIMITED | GLOBARENA ITEKNOWLEDGE PRIVATE LIMITED | GLOBARENA TECHNOLOGIES PRIVATE LIMITED

This is really really bad, found another severe vulnerability in CBSE's OSM portal. Just sent another report to CERT-In.
I had hacked CBSE's OSM (On-Screen Marking Portal) in February and had reported the vulnerabilities to CERT-In, but they were unable to patch most of them.
I've written a detailed blog post about it here: ni5arga.com/blog/posts/hacki…

and if you need an OSS variant of the same thing - i've built hodor. Uses the excellent @badlogicgames 's pi-sdk, supports gitlab/github, and you can use any model (even bedrock with custom profiles to track costs)!
You can also load custom "skills" per repo/CI job - enforce your own conventions, security rules, or review checklists.
This is what we @zerodha have been using for the past few weeks and it has caught some really non-obvious subtle edge cases/bugs.

why is 3.1 not in gemini cli? it's already available via gemini api, vercel ai gateway, opencode zen, openrouter.
why does google not want me to use their product? the mind boggles.

Assuming CC is a vast, VC subsidized training set collector for RL, I wonder how this makes any fucking sense.
They get free training data in alternative harnesses, including non-coding harnesses, for free.
The better option would have been to make this official, and hand out harness ids so they easily segment the training set.
Alas, Flicker Company's gotta flicker :)

The number of full-fledged Free and open-source software (FOSS) products and initiatives coming out of the 4th Phase, JP Nagar (Zerodha Tech), must be unprecedented for a team of its size globally.
All of these projects started as a way to solve problems we faced internally and were then open sourced. We use them at scale in our stack, and several large organisations and even government departments globally use many of these tools today.

The Takeaway:
Our study tested 131 medicine samples and found NO quality difference between generics and branded drugs - yet branded versions cost up to 14x more.
This isn't just about saving money. When medicines are unaffordable, patients skip doses or stop treatment entirely, leading to preventable complications and hospitalizations that cost everyone more in the long run.
We're not asking for price controls - we're asking for transparency. Patients deserve to know that quality-tested generics exist at a fraction of the cost. We urge policymakers to publish clear quality data, improve price visibility at pharmacies, and enable pharmacist substitution of verified generics. Affordability and quality CAN coexist (from @arifhussaintm)

The government has issued a press release saying that it isn’t mandatory for handset companies to install Sanchar Saathi. The government has no business infiltrating our phones.
While this is a welcome move, the other directive for forcing SIM Binding on Social Media and messaging accounts, has NOT been revoked.
I would call upon the government to suspend the SIM Binding directive as well, and start a consultation process on this issue, so that they can understand how it limits our usage of messaging apps.
SIM binding will impact those who use Whatsapp and Telegram on their desktops or multiple devices, inconvenience those who use Whatsapp web, and force people to buy expensive roaming plans from telecom operators, instead of a local SIM.
As per the statements made by Ashwini Vaishnaw when the Telecom Bill was passed, Department of Telecom has no jurisdiction over the Internet, and it is not the right government department for this. They have already shown how little they understand how the Internet works, and concerns that users have, with the Sanchar Saathi directive, for which also there was no public consultation, nor was their feedback taken. The same applies to SIM Binding.
I would also call upon Ministry of IT to ensure that other government departments that do not have jurisdiction over the Internet, do not hijack its remit. They have failed at this for the last three years at least.
Thank you for all your support in raising this issue. Like I used to say during the SaveTheInternet campaign for Net Neutrality, we’re in this together.
It’s our job to ensure that the Internet we love remains free, our privacy is protected, and our speech is not censored.
The Internet Freedom Foundation, which I’m no longer involved with, does exemplary work to protect our rights. Please consider donating to them. If SFLC India takes donations, please support them too. There's very little support for civil society organisations in India, and they're the ones who fight for your rights every single day.
Indian founders who benefit from India's Internet should donate to these orgs as a part of their CSR.
Also, lastly, I repeat: the SIM Binding directive also should to be revoked. More on the concerns related to that in the tweet below.

A govt application can also be used to implant files on your device.
Has happened before, in the Bhima Koregaon case where docs were allegedly put laptops & used to frame conspiracy.
Won't happen to everyone, of course. But it could, where it matters.
