arjvik··on Investigating a Forged PDF
I so wish there was a conclusion on what happened with the leasing agency
arjvik··on The Beginner's Textbook for Fully Homomorphic Encryption
Is the title broken?

I see “Unified Line and Paragraph Detection by Graph Convolutional Networks (2022)”

arjvik··on Want to piss off your IT department? Are the links not malicious looking enough?
You should totally not click this one:

arjvik··on Farewell to Meshnet
Can I ask, is Tinc supposed to be open-source-barebones-Tailscale? What are the benefits/drawbacks to a more hosted solution like Tailscale or even running one's own Headscale server?
arjvik··on Speeding up PyTorch inference on Apple devices with AI-generated Metal kernels
I believe their speedup is computed _assuming they can easily fix the correctness bugs in the kernels_.

In practice, with slight differences the model will feel almost lobotomized.

arjvik··on Writing a C compiler in 500 lines of Python (2023)
Not sure if fewer LoC necessarily implies easier!

arjvik··on Writing a Hypervisor in 1k Lines
Yes oops!
arjvik··on Writing a Hypervisor in 1k Lines
RISC-V is fully trap-and-emulate-able and so you can even do this without the virtualization extension! Though page table walks and the like will be done in hardware and thus will be very slow.
arjvik··on An LLM is a lossy encyclopedia
With a handy trick called arithmetic coding, you can actually turn an LLM into a lossless compression algorithm!
arjvik··on The time picker on the iPhone's alarm app isn't circular, it's just a long list
If you’re reading this on your iPhone, go to the alarm app, press the + button in the Alarms tab, and try to scroll to the top or bottom of the time picker
arjvik··on Compiling Dinner
This itself was written by an LLM, no?
arjvik··on Grok Code Fast 1
Fwiw Tay was unintentional and was shut down immediately upon realization… very good case study for safety folks!
arjvik··on Reverse Engineering All the Raspberry Pis
What’s a “good” RiscV board to start using for small projects?

Looking for a successor to the RPi - good documentation, easy to write bare metal for (no SDK), no surprises.

arjvik··on Ghrc.io appears to be malicious
Took the article pointing out that the c and r were transposed for me to even notice there was a problem!
arjvik··on Vendors that treat single sign-on as a luxury feature
Out of curiosity, why GitHub as the SSO provider? Am thinking about local SSO for my homelab and was debating passkeys vs tying to Google accounts.
arjvik··on "Remove mentions of XSLT from the html spec"
Purely out of curiosity, what are some websites that actually make use of XSLT?

> A handful of states, including Florida and Alabama, have banned or are considering bans on the creation and sale of the alternative protein.

Ouch. Red states are pro-deregulation, until laissez-faire innovation offends their beliefs.

arjvik··on TREAD: Token Routing for Efficient Architecture-Agnostic Diffusion Training
Isn't this just Mixture-of-Depths but for DiTs?

If so, what are the DiT specific changes that needed to be made?

arjvik··on I accidentally became PureGym’s unofficial Apple Wallet developer
> A Pass Type ID certificate from Apple Developer Portal

How much does this cost? I'd love to create Apple Wallet passes for things, but I'm weary of setting up a Apple Developer account and paying even more fees for just this.

arjvik··on Vaultwarden commit introduces SSO using OpenID Connect
E.g. the homelab admin who doesn't want their family to have to create and manage accounts on 12 different self-hosted services.
arjvik··on Vaultwarden commit introduces SSO using OpenID Connect
What's your (OSS?) OIDC server of choice?

Authelia? Authentik? Keycloak? (These are the three I see a lot about.) Something else?

arjvik··on Ask HN: How can ChatGPT serve 700M users when I can't run one GPT-4 locally?
Essentially, inference is well-amortized across the many users.

arjvik··on Ask HN: Have you ever regretted open-sourcing something?
Did you apply through the website/job posting?

I’d strongly recommend trying again and reaching out to the friend of a friend who informed you of the role and asking for a more direct intro to the hiring manager. Unfortunately, it’s really really easy to slip through the cracks as a resume, and one feels no remorse rejecting a pdf file. Even without the warm contact, some way of directly reaching the hiring manager (notably: not the recruiters!) would mean that “I wrote that library!@ becomes front-and-center, not buried as a line item. I’ve seen so much more success with myself and the people I know in cold or warm outreach than through job application portals. In fact, I’ve yet to get a callback from a single job I’ve ever applied to online!

As an aside, does anyone know why the AI labs have such bad recruiters? I successfully got a job at one and am currently working there, but I still have many many complaints about the process.

arjvik··on Ask HN: What trick of the trade took you too long to learn?
Vanguard is one of the cooler-structured brokerages. Vanguard (the management firm) is owned by the mutual funds themselves, of which you are an investor of. So their shareholder obligation is genuinely towards "clients" of the individual mutual funds. As far as I'm aware, this is the only mutually-owned mutual fund firm.

It's definitely got a solid track record and good fees, but these are things I'd feel weird about advertising it on HN for.

arjvik··on Ask HN: What trick of the trade took you too long to learn?
The HSA thing intrigued me and so I did some digging. It appears that post-65, you still have to pay income tax on non-medical withdrawals from an HSA? That is, besides the tax-free-for-medical-expenses part it reverts to a traditional IRA?

One additional trick though is that it looks like you can pay for any HSA-eligible medical expenses (incurred after you created the HSA) out-of-pocket now, and reimburse your bills at any point in the future? Thus you can still earn interest on the cash before withdrawing it at any point in the future (treating it as tax-free liquidity).

(I don't fully understand this so these are questions not statements, but hopefully I'm correct!)

arjvik··on OpenIPC: Open IP Camera Firmware
I'm confused why such a device needs to run Linux instead of an RTOS
arjvik··on Job-seekers are dodging AI interviewers
Holy shit, I’d totally pay for this!
