Hi HN community, Eric here, CEO of Voltage Park. To add some context, we're announcing a new cloud consisting of approximately 24,000 NVIDIA H100s. Each cluster has H100 SXM5 GPU's fully interconnected with 3.2T Infiniband for pea

It's not easy but it's definitely possible, especially if you can stack the deck in your favor -- line up childcare and appropriately configure your company's work culture. I juggled a day job and side-startup while my child

Ah, okay I'm trying to understand your recommendation. Is it because not every tip has a research finding tied to it, which seems incongruous with the title? Or is it that the research finding doesn't explicitly tie to the recomme

Hey supermatt, thanks for the feedback, that's good to know! Is there an alternative wording you would suggest? We meant to imply that the tips were primarily derived from findings from published research.

It’s been a whole year since the pandemic started and video calls are still terrible. We've been doing a lot of research into how to make them better and wanted to share what we've learned. We were aiming for something whimsical a

I think there's still value in hiding the conversation from the server even if you must still trust the server to not behave maliciously. If some three-letter agency contacts the server operator asking for a back channel to listen in,

You can vet who joins the channel by denying unauthorized users the room key. Users who don't have the key cannot post messages to the room. User authentication, so someone is not able to impersonate you, is on the todo list but it is

In response to kba: deadchat implements the latter option. The secret room key is shared using the RSA key exchange protocol but you're right, there's currently no way to guarantee that you're talking to who you think you ar

That's fair, I modeled some aspects of the system after FiSH-irssi, which also doesn't have user authentication or MITM attack mitigation. That'll teach me to post to HN prematurely. Both SSL with proper endpoint authentica

Hey all, great discussion. Apologies for not chiming in earlier, I posted this to HN in the morning and left for 4th of July activities, certainly not expecting it to make the front page. Here're some thoughts and clarifications: * N

Sometimes the hardware meets the minimum specs but other issues like buggy drivers lead us to have to blacklist a device.

by jeztek 14y ago
We considered publishing a list of minimum requirements but we encountered phones that for whatever reason wouldn't work even though the hardware met the minimum requirements. For example, the Nexus One and HTC Evo both had low frame rates

by jeztek 14y ago
Yeah, we wanted to support the Nexus One, and the hardware meets the minimum requirements but we encountered weird performance issues likely related to the graphics driver.

We haven't blacklisted the Droid X. Can you let us know what kind of problems you're seeing?

by jeztek 14y ago
We ran into performance issues on the N1 that made for a very poor experience. In testing, the N1 oddly worked fine when we replaced the stock firmware with Cyanogen. That would have really confused users though so we had to blacklist the

Yep, that's correct, critical sections of the pipeline are coded in assembly. Also, Word Lens only works with Android devices that have NEON support.

by jeztek 14y ago
Yep, we were sad about that one. The hardware is up to spec but there's something about the GPU driver that's causing the N1 to perform poorly.

Hi s_henry_paulson, check the app store for an update, we released 1.2 last night, which should include Italian. We've been short-staffed until very recently, stay tuned for more languages!
