Llavero Wallet – Hardware Wallet for $1/month
I created Llavero, an open-source self-hosted crypto wallet that uses AWS KMS as a personal cloud HSM. It aims to bridge the gap between custodial wallet UX and true self-custody.

Key features:
Deployed with AWS CDK with an installer or via GH Fork
. Uses AWS KMS as a cloud hardware security module
. Self-hosted Cognito for MFA and account recovery
. Costs ~$1/month leveraging AWS free tier

Architecture - First basic stack:

Frontend: Next.js hosted on CloudFront
. Backend: Lambda functions
. Storage: DynamoDB and S3
. Auth: Self-hosted Cognito for MFA
. Key Management: AWS KMS as cloud HSM

The goal is to offer the UX of a custodial wallet (easy recovery, MFA) with the security of self-custody. It's part of a larger vision for "EndUserOps" - empowering individuals to host their own secure, private services.

Looking for feedback and potential contributors!

As far as I know, xsum [1] more or less solves the problem completely: order invariant and exact, at less than 2x the cost of the naive summation. Further speeding it up may be the only avenue left for improvement.

> Do we stockpile the entire production of aluminium across the entire planet every year, and don't use it just because of politics?

Aluminium production is not fixed, it varies by demand; I'm suggesting a trivial increase in production given how long power lines last.

I’ve explored it in my 30s and it wasn’t like you described. Once I’m aware, I can change the plot by soft transition, remove the eerie elements, somewhat control flights, etc. But not too much because something monitors “glitches the matrix” and disconnects me for cheating. Not that I didn’t know who I am or what is or isn’t absurd, but thinking about it long enough wakes me up. I believe your lucidness is not too deep or something. Maybe you just found a way to see dreams in which you believe it’s lucid but it’s really not? Maybe this whole lucid dreaming thing is just a coincidence - we remember being aware, but it’s just a dream of us being aware, and mine for some reason has this “not too much” rule.
Yes, but you specifically mentioned her. I agree with you, but wanted to highlight her heroism (which in an ideal world would not have been needed)
I pivoted from "full stack" to a software and infra engineer on an AI team. There was some luck involved, but I believe it helped that I'd taken some courses. I am not one of the data scientists, but work very closely with them. This seems like a good path to full time data science.

BM42 – a new baseline for hybrid search
My issue was with "we know what modern entertainment looks like" as if humans are now incapable of enjoying themselves without a screen. And you should care about a massive market increase when it's directly relevant to the point at hand. If the initial point was "we know what modern entertainment looks like, nobody plays board games or reads books", pointing out that the board game market has more than doubled in the past decade is far from irrelevant. It actually directly counters the point.

I agree with your second paragraph, and selling the "make better choices to save the world" argument is an industry playbook favorite. Environmental damage needs to be put on the shoulders of those who cause it, which is overwhelmingly industrial actors. AI is not useful enough to continue the slide into burning more fossil fuels than ever. If it spurs more green energy, good. If it's the old "well this is the way things are now", that's really not good enough.
I have those too. But the problem is I migrated away from GMail, where everything worked even with 1 email address, so now I'm stuck with that email address being used by all the people and companies that want to send me email.

(By the way, in GMail you can move emails to "promotional" and "social" folders, and then GMail automatically does that for you for future emails; this is quite handy, but after migrating to Fastmail this is leaving me with quite a mess in my Inbox, since Fastmail doesn't have this option).

How does it actually work? I can't seem to get it to converse....
I thought I suggested many? I think it depends on what you're using the VM for. A used laptop or Mac Mini can easily host a dev environment. A hosted cloud CI/CD pipeline is better (power-wise) for compiles. A simple shell environment can be on anything. NAS etc can run on Raspberrys or routers.

On the other hand, if you're doing constant 24/7 GPU-intensive training, this thing is going to get loud, hot, and power-hungry, and it will be difficult to find GPUs to fit in there. If you're gaming, GeForce Now is going to be more power-efficient (datacenter cards with shared tenancy) than having your own on hot-standby all the time but most idling.

Maybe there is some in-between use case that really calls for a local desktop CPU? But usually I think using a recent laptop CPU would provide sufficient performance with a much lower power consumption.

Repairability was not a concern discussed in the article, but yes, it's a good thing to keep in mind if you're DIYing it. I was more concerned about the power usage scenarios.

The whole "line must always go up" is completely a self-imposed injury of our tax code. There is no reason companies can't remain healthily stagnant for long periods of time and just pay out their earnings as dividends or stock buybacks. But both are heavily disincentivized by our current tax code vs all earnings coming from gains in stock value.
... yeah, but that's just not how it works inside Alphabet. It's not rational but plenty of us would share that this is absolutely the logic that drives day-to-day business decisions across all of Alphabet's business units today.
Adding on, VLIW is only successful in AI/ML because GPUs are incapable of doing branching in a good way let alone prediction. I would guess the same story applies to DSPs. If someone figures out how to stick a branch predictor in those pipelines Im guessing the VLIW nature of those platforms will disappear overnight.

There is so much in the ML world that's being built in the open which you can use as a foundation for your learning. Some folks here already mentioned Jeremy Howard's fast.ai course which is absolutely a great place to start for anyone that a) has motivation to learn DL, and b) already knows how to code.

Beyond that, there are hundreds of open source projects you can fork to start building intuitions around what the inner loop of AI dev project cycles look like. You'll be surprised at how much of your web dev skills remain relevant in these projects, particularly in UI-related tasks. Data scientists and folks of similar ilk default to notebooks, gradio, streamlit et al. to ship interfaces for their experiments. You though have the ability to do that on your own if you choose to (sometimes a notebook is enough), which can be a valuable differentiator for you as a candidate if you also have all the other skills needed to be productive in this space.

My own background is in distributed systems with some full stack and embedded work mixed in over the years. I started tinkering with ML projects back in 2012 when I first discovered AlexNet and resources were far more limited. I was still able to get productive relatively quickly even though most of what I built wasn't really applicable to my work in a practical sense on day one. Where my background became relevant was when I needed something approximating an MLOps pipeline for data processing, training, and eval. Most of the code you're writing for that isn't really specific to ML, its nearly identical to CI/CD systems but with the obvious infrastructure caveats native to ML workloads.

Nowadays though, especially if you're intrepid/resourceful, there is so much more learning material by comparison and much of what you work on can likely augment your day-to-day web dev tasks as well if you're creative enough.
FreeDOS is pretty useful if you happen to need it.

Back in the day my go-to method for making DOS boot disks was to find a win9x machine and type "format /s". That used to be easy to do, but there are no more abundant Win9x machines anymore. FreeDOS was an alternative to that.

The last time I used FreeDOS was a few years ago to flash a bios update that required DOS to do so.
He did, and that's a fantastic article which is worth the read and provides good context for interpreting this post.

One thing this post adds is the simple rectification of replacing ret with another br instruction, so the pairs are again "mirrored", and you get to have your cake and eat it too - slightly faster code without breaking the branch predictor.
if it fits on a disk I can just email it to you, or email you a link to cloud storage download. The cost of doing this is essential $0. Diskettes are just obsolete.

Yes this is exactly it. The gold standard is bit-4-bit matching when shifting code between systems. If you move your code to a new system and get different results --> is it due to different summing order, or something else wrong? By ruling out the former you're more likely to get the bit-4-bit match and thus avoid a lot of debugging effort -- or spend it solving a real bug.
My experience on fastmail doesn't align with yours. While spam has slightly increased over the years, I attribute that to just using my email more often. It's very rare that I get spam in my actual inbox. In fact, my experience is that the spam filter is a bit too strong and I actually have to check the spam folder now and then.

For the promotional emails, there are some general rules you can set up to catch a lot of it, such as https://pietrorea.com/2021/10/22/filter-emails-by-the-list-u.... However, the best way to manage them is to actually just unsubscribe to them as you receive them. If unsubscribe is ignored, then blacklist the sender.

For general spam, there's a setting under "privacy and security" to make the filtering more or less aggressive. My setting is on "standard" and I haven't had any problems, but you could try adjusting that.
I'm really tickled by a lot of the stuff on your page. For example your own backgammon interface language (UBEI) - I'm also coming up with a language (UCGI) and slowly translating our clients, bots, analyzers etc to use it :)

I try to think about what should be a framework and what should be a library. Libraries are tools that helps you achieve a task, for example, building a prompt, calling LLM models, communicating with vector database.

Frameworks are more process driven for achieving a complex task. This is like ReactJS with their component mode -- they set a process for building web application such that you can build more complex applications. At the same time, you have lots of flexibilities in the implementation details of your application. Framework should provide as much flexibilities as possible.

Similarly, we are trying to build our framework for streamlining the process for LLM development such that you can iterate on your LLM application faster. To help setup this process, we enforce very high-level interfaces for how you build(input & output schema), evaluate, deploy your application. We provide all the flexibilities to the developer for low-level implementation details and ensure it's extensible so you can also use any external tools you want within the framework.
Gemma2 might be good enough for a drop-in option as well. The benefit for those who built on ChatGPT API is that as more open weight models get released, they can silently migrate their API usage to self-hosted models … ChatGPT allowed them to prove product-market fit early!
Could you please elaborate a bit more? I am your typical web-dev/frontend/backend developer, don't really know much about what is involved in data engineering.

Do you mean collecting, cleaning data? Or setting up databases (if yes, how is it different from me managing my employer's databases, except for size)?

In other words, what does a data engineer do all day?

Surprised to see that a lot of people experience lucid dreams. Are there any solid techniques to trigger them?
As I’ve read your replies, it sounds like you’re defending Agile, not Scrum. Scrum is more prescriptive. I’ve never worked in a Scrum shop or even heard of one that didn’t have all the features commonly associated with it: burndown charts, backlog refinement with some kind of pointing consensus, retros, and a scrum master that drives all of these.

Could you provide some material that explains how to do Scrum in a different way?

That brings up a good point. Let's say I am the founder and I send out my first 5 invites to the "highest quality" people I know. In this case "highest quality" is people who wouldn't be susceptible to bribes. Assuming that at the start of the invites, I have a certain set of standards, how would you propogate those standards forward over time? Is decay inevitable with growth?
The counter to that counter is that I have been told that software jobs in Germany start out as very low paying. My friend who moved to Germany to work as a programmer ended up only getting about $30k a year to start, which at the time was less than half of what our peers were making in the US.

That said, I think probationary periods are one of the best ideas the US needs to adopt.

There are a few examples of oral cultures ensuring perfect transmission across a large expanse of time.

One example is the several different recitation styles used to memorize Sanskrit verses. These methods give memorizers multiple ways to remember a line, and also prevent errors like the inadvertent mixing of adjacent words (" euphonic combination"). The "checksumming schemes" are far more elaborate than you'd imagine. [1] The result is perfect transmission of text and its pronunciation, including pitch accent.

Another example is a "multi-party verification" scheme in some Aboriginal Australian cultures. "... storytelling among contemporary Aboriginal people can involve the deliberate tracking of teaching responsibilities. For example, a man teaches the stories of his country to his children. His son has his knowledge of those stories judged by his sister’s children—for certain kin are explicitly tasked with ensuring that those stories are learned and recounted properly—and people take those responsibilities seriously. ... the 'owner-manager' relationship, requiring a story to be discussed explicitly across three generations of a patriline, constitutes a cross-generational mechanism which may be particularly successful at maximising precision in replication of a story across successive generations".

Getting the world to switch timescales is orders of magnitude more difficult that redefining currently used timescale. The latter can be done in the BIPM backrooms by small committee, the former needs action and agreement from pretty much everyone.
> either UTC or a Unix timestamp (which afaik is essentially the same as using UTC except that it's less easy for most people to read at a glance)

UTC has leap seconds, unix timestamp doesn't. It's defined to have 86400 seconds per day, so there's no place to put a leap second. Instead, it either duplicates a timestamp or does "leap smearing" - slightly changing the duration of a second around where the leap second is.
