darzu··on Programming languages endorsed for server-side use at Meta
I wouldn't put much stock in MSR languages until they get usage in other orgs. There's at least a dozen research languages in flight at a given point in time.

They used to have this great site were you could interact with them all: https://web.archive.org/web/20180130101736/https://www.rise4...

Microsoft has been using it internally as well.
darzu··on The Dangers of Microsoft Pluton
The first xbox was hacked using an attack via the power supply I believe. It caused some instructions in the boot sequence to be skipped i think. It’s a really cool story, wish i had a link.
darzu··on The Dangers of Microsoft Pluton
It’s worth distinguishing between security against software attacks and security against physical “attacks”.

I absolutely don’t want my internet connected pet cam to be accessed remotely (outside the set of companies i’ve decided to trust, namely the manufacturer.)

Protection against hardware tempering is less good and probably mostly anti-consumer. The most legitimate cases I’ve heard:

- Protection from (some) supply chain attacks

- Leasing models. Where you acquire the item for less than it’s hardware cost and pay over time.

But honestly I’m not convinced of either.

Disclosure: I worked on Azure Sphere, the first place Pluton was developed outside Xbox.

Edit: I’ve read the whole article now. These scenarios are really bad and really realistic. Pluton is bad.

darzu··on Emoji Kitchen
https://emoji.supply/kitchen/?%F0%9F%A6%82+%F0%9F%A5%91=7vu It’s got a share feature. Kinda wish they put the emoji in the url haha. Edit: ah hn strips emojis.

If you’re working on open source, stream straight to YouTube or Twitch. Can be private or not.

I do this sometimes. the accountability hack works even better if someone could be watching.

Bonus points is that it feels way more natural to narrate aka rubber duck problems when you are streaming.

darzu··on Ask HN: Is having a personal blog/brand worth it for you?
This doesn't match my experience. If a candidate advances far enough that 3-4 of us are going to spend a couple hours of our day interviewing and deliberating, we each will at least scan resume linked blogs.
darzu··on Unity merges with IronSource
What? The video games is nearly a $200 billion dollar industry[0] and Unity is one if the most popular engines, if not the most. How is that a “mountain with no gold”?

They could have hired less people and tried fewer risky non-core investments. Plenty of tools-only companies survive well indefinitely.

They got greedy. The grow into a unicorn or die trying mentally is cancer to good technology.

darzu··on How CUDA Programming Works
To the contrary, this is my biggest complaint with CUDA. It's a nice seeming abstraction from a programmer's perspective, unfortunately it's not a good abstraction b/c it doesn't match the reality of hardware. The truth is there is a heterogeneous arena of memory kinds, access patterns, and sizes that gives you drastically different performance trade offs for different tasks. (This isn't even about diverse hardware, every modern GPU has this complexity.) CUDA oversimplifies this which causes solutions to have opaque performance cliffs and you end up having to understand a lot of the underlying complexity and then awkwardly back-propagate that up into CUDA's ill-fit APIs to get decent performance. It's a false sense of simplicity that ends up causing more work and complexity.

Contrast that with something like WebGPU where their notions of GPU buffers, textures, pipelines and command queues maps well into what actually happens in hardware and it's much simpler to get predictable performance.

Now I totally agree there needs to be more work done to provide simpler abstractions on top of WebGPU/Vulkan/Metal/DirectX for certain common patterns of work. But pretending you have a pointer to a blob of GPU memory isn't the way.

This talk gives a great overview of the GPU compute landscape: https://www.youtube.com/watch?v=DZRn_jNZjbw

darzu··on FCC commissioner wants TikTok removed from app stores over spying concerns
Let’s run a thought experiment:

All videos get assigned a 0-1 anti- vs pro-CCP score. Videos with a >0.5 score get a slightly (~5%) better chance of being shown, and <0.5 is slightly penalized. This would be undetectable if the algorithm is run off device. Anti-CCP content would still play often. But on the massive scale TikTok runs, this would still tilt opinion favorably towards CCP.

darzu··on USDA ignoring the science on low-carb diets
Our vineyard didn’t make as much money as surrounding vineyards but it was still self sustaining. More robust demand for organic wines would have made it even more so.

Organic farming has external benefits as well, or rather the absence of negative externalities like harmful chemical run off and less water usage. These aren’t as easily noticed by just looking at market dynamics currently.

All that being said, my understanding is that organic farming isn’t the right choice in all cases. It’s definitely more labor and sometimes resource or land intensive. It takes a certain wealthy consumer base to support it.

darzu··on USDA ignoring the science on low-carb diets
Citations needed. I worked on an organic vineyard for a summer and I can tell you it took a lot of work to get that label.

Non-organic vineyards in our area had barren earth or gravel under the stalks as they used weedkillers regularly. In contrast, we practiced “turf flipping” where we would, with clever machine and hard work, turn the soil over to smother weeds. The soil was alive and rich with the longest earthworms I’ve ever seen. This took incomparably more time than spraying chemicals but we believed in the mission. And the extra money from labeling it organic didn’t come close to covering the extra effort.

In some cases at least, the label means something.

darzu··on Meta VR prototypes aim to make VR 'indistinguishable from reality'
For instance, my Rift 2’s left controller died for unknown reasons and Meta has been “out of stock” for a year on this part and the Rift 1 controller is “discontinued”. You can’t even find it on ebay. $500 out the window.

YouTube or google site:reddit.com usually yields the best actual human reviews for me.

Or specific categories like America’s Test Kitchen for kitchen stuff.

Last I checked, there were no mechanical keyboard using dongles. Way better than bluetooth.
darzu··on Logitech MX Mechanical Keyboard
I have this and it’s nice except I would much rather have a dongle the bluetooth.

I haven’t found any wireless mechanical keyboards with a dongle until this Logitech one.

This comment would read as sarcasm today.

darzu··on MIT graduate students vote to unionize
I have 7 close friends that graduated with CS PhDs from UW in recent years, and they all feel positively about the union.

Here's a table from the union comparing before and after unionization in 2004: https://www.uaw4121.org/wp-content/uploads/2020/10/UW-ASE-Be...

darzu··on Covid and the Heart: It Spares No One – Johns Hopkins
What’s the effect size? Didn’t see this anywhere in the article and seems pretty important to know.
darzu··on Reducing the risk of nuclear war should be a key concern of our generation
I'm a little confused about how nuclear winter works esp. in relation to climate change, maybe someone here can enlighten me.

The article states: "large columns of smoke and soot rise up [...] to the stratosphere. There it [...] blocks the sun [...] The nuclear winter [...] is expected to lead to temperature declines of 20 or even 30 degrees Celsius (60–86° F)"

So "smoke and soot" placed in the stratosphere lowers the earth's temperature, yet C02 in the atmosphere raises earth's temperature? Why?

Follow up naive question: can we strategically place smoke in the stratosphere to counter global warming? What are the consequences of that?

FYI, in case anyone else has a hard time finding what exactly the hours reduction is.

darzu··on Ask HN: What does one look for in a laptop these days?
Yes, Surface devices have this problem. It was a frequent occurrence for me to put my Surface Book into my bag and later take it out completely dead or hot and drained.
