In my case, the algo is pretty good at surfacing useful tweets and people: both new stuff that I find relevant, and tweets from the people I'm following that I missed.

So I generally use lists to interact with different groups of people I'm already interested (including the ones I'm following) and the homepage is great for discovery.

I was bullish on Intel all of last year but I think it’s effectively dead money until 2024-25. Between AMD and Apple, Intel is so far behind. Their GPU launch is also an indication that they are very disorganized.

It's nice that you are able to do this, but most don't use social media this way. They see successful, beautiful people doing interesting things and they feel sad that they can't do the same. Can't you empathize?

This article focuses on returns of VC investment. Nothing wrong with that except it doesn't mean VC is going to tank. The nature of VC generally means a hyper focus of thematic investment. The market has everchanging needs and demands. I expect the direction of VC is changing its focus (already is) toward climate, food, and lifestyle health. VC firms may be cutting back on tech-tech, but they are increasing their contributions toward the topics I listed above.
Let's say you're trying to train an model to predict if a patient has a cancerous tumor based on some imaging data. You have a data set for this that includes images from people with tumors and people without, from all races. However, unbeknownst to you, most of the images from people of race X had tumors and most of the images from people of race Y did not have tumors.

If the AI is also implicitly learning to detect race from the images, it's going to learn an association that people of race X usually have tumors and people of race Y usually do not.

The problem here is that the people training the model and the clinical radiologists interpreting data from the model may not realize that race was a confounding factor in training, so they'll be unaware that the model may make racial inferences in the real world data.

If people of race X really do have a higher incidence rate for a specific type of cancer than race Y, maybe this is OK. But if the issue is that there was bias in the training/validation data set that was unknown to the people building the model, and in the real world people of race X and race Y have exactly the same incidence rate for this type of cancer, then this is going to be a problem because it's likely to introduce race-specific errors.

Local inprocess databases might be a bigger thing, but won’t they do nothing to help cases where 10 different applications on different machines need to read and write in the same database?

>> "Following separation from the aircraft, the ARRW's booster ignited and burned for expected duration, achieving hypersonic speeds five times greater than the speed of sound," it said.

Big deal. The booster is just a rocket. And Mach numbers are meaningless without altitude reference. Anything that travels to the outer atmosphere/space will hit extreme Mach numbers on the way up/down. So without any further data the above statement means little more than "we fired a big rocket". Did the sustainment motor, the air-breathing thing that differentiates a true hypersonic from every other rocket, did that motor function in cruise mode? Or is this essentially just a boost-glide ballistic missile?

this is a major hassle when converting from avro (from kafka which uses a schema registry, so schemas are not shipped with the avro data) and storing in parquet which requires a schema in the file but you can 'upgrade' it with another schema when reading it. It would be great to have a binary protocol-like format (schema-less avro), and a schema-less columnar storage format.. which is I guess is what these guys are doing.

Ask HN: Is there a descentralized DB with a simple social conflict resolution?
I've been thinking it might be practical to build a simple decentralized database, where agents just know each other, so conflict resolution does not need to be so complicated and rely more on the social layer.

I think this applies to most databases, but I'm particularly thinking of internal enterprise databases, some social networks, any federated database system, and different devices of a single user

I'm thinking of this features:

1- Append-only?, full history of operations. Deletes / edits do not remove data, they only modify the "active state"

2- Agents are public keys or similar (DIDs?)

3- Operations are signed, and receivers verify if operation is valid, and sender is allowed

4- Operations form a Merkel-DAG (similar to git, they link to the tips of current "active state", like a commit/merge in git)

So far I think I've basically described [OrbitDB](https://github.com/orbitdb/orbit-db)

Consensus is where things get real hard, [OrbitDb seems to use a last-write-wins CRDT](https://news.ycombinator.com/item?id=22920204), and although I don't know the details of orbitDb, I think for many simple use-cases, conflicts can just be resolved on the social layer. But I think we need to provide agents with good tools to resolve conflicts

I'll try my best here with some ideas:

When merging, we can order operations by their timestamp, if operations enter conflict, raise it to the conflicting agents, or someone with permission to solve them.

If an agent makes public an operation that forks its own history, mark agent as malicious or compromised, alert other agents, this needs resolution on the social layer, you have proof of misconduct, an agent has signed diverging operations

Any operation becomes fully settled if you have proof that all agents of your system have referenced it directly or indirectly through newer operations.

Timestamps can be upgraded by using opentimestamps.org to get proof that an operation existed at time X (prevents creation of operations in hindsight). Though this does not prove operation has been made public

I had a very similar experience with Nibbles. It was my first time reading a program and modifying it. The initial motivation was that we'd bought a new computer and it was suddenly unplayably fast.

>I can't speak for all of Europe, but here in Amsterdam most people have a decent supermarket within walking (<15min) or cycling (<5min) distance

I lived in downtown Boston (USA) for a number of years in 4 different apartments. In each, the kitchen and fridge were fairly small, but I had a neighborhood market no further than a 2-3 minute walk away. A larger market was only 10-15 minutes away. As a result, I tended to eat far more fresh produce since I went to the market almost every day and had little space for storage.

Now that I'm in the suburbs, I have to drive to the store, but I generally don't more than one to two paper bags' worth of goods at a time. I still don't shop for a whole week, even though I have the space.

Wow! I can't believe someone else had the same formative experience that I did. I remember this was how it all started in software for me! There was a local newspaper interview I did in high school (one of those "spotlight a student" type things) and I said that I wanted to work for Microsoft in it. It was all because of QBasic and Nibbles! Thanks for the write-up, that definitely brought back memories.
I’ve enjoyed Twitter as a way to find experts on Ukraine. But it seems pretty niche. It only seems useful to me for extremely recent events on unfamiliar topics.
Just plain retweets tend to be viral tweets. And while some of them can be fun they also have a tendency to be low-content, high rage-factor tweets.

In tweetdeck the block retweets setting blocks them. Retweet with quote isn't counted as a retweet.

I'm pretty sure that "Russian" is an ethnic group (and "German" and "Irish" and ...), and yet the "Russian" ethnic group is going to get called "white", so it's weird not to consider whites as having ethnic groups (which any statement that compares the number of "ethnic group" members to the number of "whites" is implicitly doing).
True. But I think one can avoid the credibility damage presenting or appearing poorly over time can cause with just a little thought about audio and lighting etc. There are gains to be had simply by being seen and heard better even if there is low ‘diminishing returns’ point.
He was probably using software, like Canon's Webcam Utility, to stream his camera's HDMI OUT to his computer instead of using a capture card. He likely did this because of his camera not having "clean" HDMI output (i.e. you'd see icons if he were to capture what was on his camera's screen). Software like this is extremely unreliable by comparison and consumes CPU cycles like crazy, both on the camera and on your computer.

Additionally, for most cameras, the input feed used by the software goes through the camera's image processing stack as if they were using the real-time "Live View" feature (i.e. showing you the image you're going to take post-processing, i.e. real-time image processing). This often heats the camera up and causes it to shut down due to thermal overload. If you use a capture card, it captures whatever's on the screen without hitting the image processing stack, which is much less resource-intensive.

The first person I interviewed with this setup had the same problem. He looked great, but the software processing the input from his camera made him lag horribly.

I have a Canon M200 mirrorless SLR with an Elgato HDMI Capture card and have used it for all-day online meetings (even through OBS!) with no issues at all. Startup takes me, like, 30 seconds: turn key and fill lights on, turn camera on, press hotkey to start OBS, Krisp and Zoom, turn on video.
Ask HN: What percent of all potential knowledge is understood by humans?
If you were to take an estimate of all knowledge in the universe, what percent of this do you suspect is understood by humans?

Secondarily, what percent of information we perceive to be facts is actually false across all disciplines?

Probably just us flexing that we have them too. Likely have had them, but kept it quiet as no need to declare our capabilities. Since others are crowing about it, just letting them know we also have same.

I interpret this as hiring freeze.

When I read corporate emails and “official” messages, I always take the least charitable interpretation. So what’s the most unattractive thing that fits their definition of slowing down, that’s a hiring freeze.

This uncharitable view is the opposite when I encounter genuine human interaction where I try to view the most charitable.

But if a lawyer has read through it, then the most weaselly interpretation is probably truist.
> Maybe plug in a software-defined radio and antenna: possibly helpful for scanning frequencies for useful/helpful broadcasts.

Foldables are a crappy solution. I do not want a tablet.

I understand that they fold up to essentially become weird-aspect ratio very thick phones... but that's not desirable for me either, especially at the foldable price point of ~$1000+.
This has much broader implications than first meets the eye.

People are used to getting a second opinion on healthcare, but in a quantified data-science era that can loop back to multiple quantified estimates as well. It has implications for policy, individual decisions, and all sorts of things.

The issue here is that jurisprudence heavily depends upon established precedents that hinge on particular logical and semantic structures present in legal texts. The more you deviate from the norm, the more likely you are to end up in court due to disagreements over interpretation. Safer to stick to what has already has a consensus behind it.
I’m definitely sorry to see senior people leaving (or losing) their positions at an iconic company, especially amidst this weird public uncertainty about its future.

However, Twitter’s core product has stagnated for too long. I don’t expect (not necessarily want) drastic overhauls, but even many of the features in the interface feel like half finished prototypes. Even attaining feature parity between desktop and mobile (I still have to switch to desktop to schedule a Tweet because it’s missing in mobile) would be a step forward.

I only know a few people who have worked at Twitter recently. I asked one of them (product person) what he did while he was there and he admitted he couldn’t really give me a good answer. That’s obviously an n=1 anecdote, but it tracks with what I see from the outside.

Maybe this wave of management changeover will loosen up some of the stagnation.

I feel like a lot of people complaining about Twitter only experience it through the twitter.com web interface. I'd hate it too if that was my only experience of it. Using Tweetdeck and/or just about any mobile client is worlds better. You don't get so much random dreck, which makes it much easier to see and engage with people you actually know or like.

As far as I can tell, using any social-media site other than with a friends-only reverse-chronological feed is just going to be a bad experience for anyone who values real engagement (i.e. not influencers or wannabes and not passive disinformation consumers). Also, any social-media site without a block button and a culture encouraging people to use it is broken too.
> We have killed 1550 people this year for the death penalty.

You're considerably off with that. In America, 6 people have been executed so far in 2022 and 11 people were executed for the whole of 2021.
Agreed. Using an SLR with a capture card and proper three-point lighting makes you look amazing in online meetings. Very easy to set up as well. Will cost about $700 to get going with, but it's a one-time cost that will work on any computer for a long time.

Not every camera has clean HDMI output, though. It's hard to find a single list of cameras that have this feature, so you have to Google around. Cameras without clean HDMI out will show icons and focus windows when you stream from them.

Sonshi Style – A Style of Putting HHKB Keyboard on Laptop
As an iPhone user, I've wanted to use an iPhone Mini ever since they came out. It was hard to compromise on the camera, coming from a Pro device, but I finally made the switch when the iPhone 13 Mini debuted.

Within 24 hours however, I was back at the Apple Store returning it. What was the issue? Nothing wrong with the device at all - it was everything I hoped it would be! Unfortunately, the issue was with the apps instead.

Developers have gotten so used to everyone being on bigger devices. Since the Mini _lowered_ the standard size of a device (and represented such a small audience), I found that most of my apps had various UI bugs as they were written to target a regular iPhone dimension or larger. In some cases, apps were unusable due to the UI bugs.

As an iOS engineer, I can also speak to the development side of things. At the various places that I've worked, I can't say that any testing was ever specifically done on a device smaller than the smallest _regular_ iPhone (like an iPhone XS). Even our team of QAs had all kinds of devices that they'd use and we had automated UI testing, but an iPhone Mini was consistently overlooked.

Maybe the device will be better in the future, but until then, the apps just aren't ready.

Granted this is my experience with iPhones and iOS apps. Android could very well be in a different place. I expect less out of the app development on that platform, however, developers are also more attuned to targeting smaller screen sizes, given how many Android devices exist, so it could indeed be a better experience if you find a device that you like.
For devs, MacOS is still pia. Asahi is still far behind. I just don’t get why Apple wouldn’t embrace Linux. Who’s stopping that from happening now that Jobs is gone?
Okay wow. I didn't tools like this existed! There's been more than once where I've found myself in a situation like "find all code like this, change if this, delete if this". Regex can only get you so far.
