In the same vein, distributed DBs are not required for most companies (from a technical standpoint; data locality for things like GDPR is another story). You can vertically scale _a lot_ before you even get close to the limits of a modern RDBMS. Like hundreds of thousands of QPS.

I've personally ran MySQL in RDS on a mid-level instance, nowhere near close to maxing out RAM or IOPS, and it handled 120K QPS just fine. Notably, this was with a lot of UUIDv4 PKs.

I'd wager with intelligent schema design, good queries, and careful tuning, you could surpass 1 million QPS on a single instance.
That's an interesting technology. Could it be used by everyone, in civilian guns? It might prevent a lot of bystander casualties from stray bullets, richochets, etc. OTOH, perhaps for bullets that hit, explosions occur on the target? That would not be good.

(Tracers would be useful for bystanders and law enforcement. Self-detonating or not, maybe all ammunition should be tracers?)

100% agreed about the ecosystem too. We've already created a perhaps-too-scrappy package manager, but it works! https://packages.atopile.io/
We're pretty convinced that the awesomeness of the software ecosystem is a function of its openness and open-source and atopile largely came from working out how we could seed a similar shift in the hardware world.

In mathematics classes I cannot imagine how to used LaTex and/or vim to draw and shade the area under a curve to represent the integral. I have my lucky Pentel Mechanical pencil which took me over hours long tests back when I was in school. It is completely broken know but I keep as some sort of amulet. Only 3 people needed to understand my writings: The teacher, the TA, and me. I once had a heated argument with a TA. I wrote a hex number and I write the four closed, like this (4) But it was mistaken for an (A). I wished then the tests where typed.
As long as I don't get interrupted constantly, I like going to an office if it is conveniently located and has perks.

If I can save time by getting lunch quickly, have snacks and coffee available, and have an onsite gym, I can basically make back the time I commuted and I get a little more 'separation'.

Most of my day is working alone, so occasionally being able to grab lunch with a coworker or someone is nice, and it is very nice not to worry about what snacks and drinks to buy etc.

I realize not every office has these perks, so i'm extra appreciative of when I have it.

I was at a ballroom dancing competition. I wasn't competing, I was there to support some friends, so during the free practice sessions between rounds I asked various women if they would care for a dance.

So my first words to the women who would become my wife were:

"Would you care for a quickstep?"

If you want to find a SO then you need to meet people. If you want to meet people you need to go where they are. So you need to have hobbies or activities that allow you to meet a wide range of people. You will already have at least one thing in common, so that's a start.

Go to a juggling club, or a walking club, or a dancing club. Play ultimate frisbee, join a maker space. Go and be where people are talking to each other.

Or use an on-line dating site and rely on the algorithms.

This discussion and the points being made are totally valid and reasonable. But I think there's one thing they completely miss, which is the cultural impact of VC.

Given the massive success of software companies over the past decade or two, hordes of driven, talented, and smart young people have joined VC-backed companies or aspire to do so. It's become culturally accepted that if you're an ambitious person, you should be working at - or better yet, founding - a venture-backed company.

The societal opportunity costs of this phenomenon are significant. I know dozens of young, talented people who are founding companies for no particular reason, simply because it's become the default path for what they're supposed to aspire to.

Is this the "fault" of venture capital? Not really - VCs are just trying to attract talented founders and make their portfolio companies successful.

But by doing so, they've created a negative externality, which is that VC has become the gatekeeper of perceived "success." That means fewer talented, high-energy people working in government institutions or critical industries - precisely where those talented people could have the greatest impact on society at large.
I think the problem is that people are relying on this for actual security. The article demonstrates how easy it is to get companies to accept this form of fraudulent authentication (and the demand for this service speaks to its efficacy as well).

> stripped of rights

They're not being stripped of their rights; they're acknowledging that what they're about to say can be used against them.

Waiving rights is common in American law. Open source licenses waive the right to sue; the third-party doctrine waives the right to privacy of the data that companies take. To some extent, liability releases for participating in dangerous activities waive the right to hold the company you're paying responsible -- think climbing guides, race tracks, sky diving outfits, etc. But from what my non-lawyer self understands, there are some rights you can't waive, like the right to sue over gross negligence.

In this case, it sounds like that waiver was used more as an intimidation tactic to make the suspect believe that they were stuck there and couldn't decide to stop talking. Which... That sounds like something you'd get a lawyer for to help explain the situation.
I think you would typically need a physical ID, not a picture, and one person couldn't tip the scales in any election.

> Part of it is finding a company that doesn't work you to the bone

Definitely a big part of it. A job where your manager/boss doesn't hold you to unreasonable output, implicit overtime requirements, and one where your manager/boss respects you enough to not do that is a big thing, makes a big difference in what you have time and energy for.

Having a job that lets you focus is also a big part. Being on a team where you context switch 2 or 3 times a day because something is on fire vs just focusing on one thing all day, no 2 or 3 hours of meeting leaves you less exhausted as well.
Feeling the frustration of owning a Victron EVC300400300 "integrated" with my p.v. (WFH, so I can recharge my car during many days) I've used a ShellyPro 2 to power on a small 2kW resistive heater for few minutes, drop the load and power cycle the EVC.

VERY often this device in "auto mode" (charge from p.v. varying charging current following maximum p.v. production) in a zero-injection to the grid setup decide there is not enough p.v. power available even if it's totally false. Since Victron have not added a "force start" option I have done mine. When the EVC see the extra power available just after restarting it star charging...

A very good example of the crappiness level and logic of actual IoT... Another simpler automation is for my VMC (AirWell AirFlow 250-N91, witch I discover that's also Clivet ElfoFresh and other names, since it's a Chinese machine rebranded by some integrators in various country) that in auto mode when there is a very sunny winter day with mild temperature and the home due to the southern large windows start to heat way too much it keep running the compressor injecting absurdly hot air instead of passive cooling. The automation is simply ModBUS via HA to switch from auto to "ventilation only" and switch back if the outside temp goes lower than 7℃ since the VMC refuse to ventilate below 7... Even if I have 25 inside.

Another of the same kind for my domestic hot water heater, Daikin/Rotex M2O EKHHP "a machine for the future in the present, ready for renewables" etc etc etc that's so ready that the sole automation available are 2 dry contacts that allow to

- run full power till the water reach a certain threshold (that I can't set, 62℃ hard-coded)

- run the compressor (heat pump only) for an hour than the resistive heater + the compressor

- do not run

- decide autonomously what to do

Daikin engineers have essentially not counted p.v. in their design but just different grid tariffs during a day. There is no way to tell something like

- do not run

- run ONLY the resistive heater (following water temperature, of course)

- run ONLY the heat pump

- run both

Way too simple apparently for their mind... As a result when I have enough spare p.v. HA flip between the "do not run" and "run the heat pump than also the resistive heater" every 15' to keep just the heat pump. Run full power if there is more spare power, but no way to tell, run just the resistive heater (2kW instead of 2.6-2.8kW). It's nothing special in economical terms, just my desire to optimize self-consumption, but the design of ALL current IoT appliance are obscene and demand obscene hacks to use then rationally simply because their designer never though nor about integration, nor about a vast set of real world scenarios.

At least in MA, you have to pay the sales tax in order to register the vehicle. It doesn't matter what state you bought the car in.

The regulators aren't letting that loophole slip in. Everyone here goes to NH to skip out on sales taxes, including the regulators that pass the sales taxes.
I've built several things! These include bots for code generation that you can tag onto issues, q&a on text etc.

The thing I'm working on now is AI mock interviewing. It's basically scratching my own itch, since I hate leetcode prep, and have found I can learn better through interaction. To paste a blurb from an earlier comment of mine:

I'm building https://comp.lol. It's AI powered mock coding interviews, FAANG style. Looking for alpha testers when I release, sign up if you wanna try it out or just wanna try some mock coding. If its slow to load, sorry, everything runs on free tiers right now.

I really dislike doing leetcode prep, and I can't intuitively understand the solutions by just reading them. I've found the best way for me to learn is to seriously try the problem (timed, interview like conditions), and be able to 'discuss' with the interviewer without just jumping to reading the solution. Been using and building this as an experiment to try prepping in a manner I like.

It's not a replacement for real mock interviews - I think those are still the best, but they're expensive and time consuming. I'm hoping to get 80% of the benefit in an easier package.

I just put a waitlist in case anyone wants to try it out and give me feedback when I get it out

Gonna apologize in advance about the copywriting. Was more messing around for my own amusement, will probably change later

> further education in valuable topics is valuable to people even if they are not motivated

Sure, but that doesn’t need to be college. Many European countries have colleges in name only that actually function as trade schools. An unmotivated learner should go to a cheap 2-year trade school and then start earning.

> college is about getting people into massive debt to fund college administrators

Completely agree. That said, we have standout colleges where the purpose is to educate our next generation of elites. That’s still important.
I built an Interactive Resume AI chatbot where anyone can ask questions about my experience and skills:
https://www.jon-olson.com/resume_ai/

The backend is a Python FastAPI that uses ChromaDB to store my resume and Q&A pairs, OpenAI, and Airtable to log requests and responses. The UI is Sveltekit.

I'm currently building a different tool and will apply some learnings to my Interactive Resume AI. Instead of Airtable, I am going to use LangSmith for observability.

I started writing and my Substack articles are also linked to via my website. I'm currently working on applying sentence window retrieval and that article will be out shortly. This is part of a #buildinpublic effort to help build my brand as well.

I've been unemployed since Sept as a Senior Software Engineer. The market is tough so I'm focusing on the above to help get employment or a contract.
I'm not a chatbot – I promise!
The last thing I put a lot of time into building, I took on a prominent VC as a business partner. That was a ~7 year partnership. Overall it was a good experience and yet I still find myself not wanting to do it any longer (give up equity to VCs).

When your partner is a billionaire you find it's a lot more challenging to do things exactly the way you want to, to live by whatever your vision for the thing is, and to tell said billionaire no if there's a disagreement. It's not that you can't per se, it's that there is definitely additional relationship and operational risk to the context, additional calculation. It's very common for big investors to have big egos and big opinions. Pleasing investors becomes a thinking mistake problem that you have to manage. That's a mental cost to keep at bay and it gets old/tiring. The same is true whether the VC is prominent or just your average SV VC, and it persists whether it's a small number of investors or a lot of investors you're dealing with.

Besides the obvious that venture capital isn't always right for every business or every business stage, sometimes it's never right for certain organizations. I'm working on a social network that will operate either as a public benefit corporation or non-profit org. There's no place for outside investors in there. Even if you eventually return to dealing with investors, do yourself a favor and build without them from time to time, at least for extended periods of time; it's refreshing to the soul if building things is what you really like doing.
"mislead the focus" should be a valid and common way to describe this kind of thing.
Common definitions of 'income' exclude wealth transfers, including cash transfers like refundable tax credits. The data don't make sense because the data are intentionally obfuscated.
I'm skeptical someone would risk giving their child a significantly worse education in the off chance it might give them a marginally better chance to get into a top university. Regardless high income families moving to low income areas to go to those schools I would assume would be a net benefit for all from a tax perspective. Some of those taxes would presumably go right back to improving the local schools for everyone else.
It’s a footgun for sure though, since the “obvious” comparison function of subtracting arguments is intransitive with integer overflow.
Bear in mind that comparing floating point NaNs is not transitive. IIRC, Rust considers floating point unsortable for that reason.
maybe they think the disclaimer was unnecessary or misguided if there's no actual difference between neurotypical and neurodivergent there?
But being footguns is a feature of C/C++, not a defect: they trade safety for performance by design. (Edit: Wrong trade-off in my opinion, just to make it clear.)

Do you think standard of care already includes collecting the vast amount of data required to understand a treatment's effects? Medical providers aren't trained to execute clinical trials. They can do bits and pieces, but they still need extremely strong, close oversight from an actual researcher. Someone ultimately has to hold liability for trial participants too, and no one is going to take on the liability of an untrained care provider to administer a trial to a patient.

Additionally, the pharma company wouldn't allow this because in addition to the upfront design complexity, it would put the trial itself at risk. You're not really allowed to say, "just try it in a bunch of people, it's okay if untrained folks mess it up because if they do we can just throw out the data."
Pearl-7B-slerp, an xtraordinary 7B model for maths
Pearl-7B-slerp is a merge of the following models using LazyMergekit:

Spherical Linear Interpolation (SLERP) serves as a technique for seamlessly interpolating between two vectors while maintaining a constant rate of change and upholding the geometric properties of the spherical space in which these vectors exist.

Opting for SLERP over traditional linear interpolation is motivated by various considerations. Linear interpolation in high-dimensional spaces may result in a reduction in the magnitude of the interpolated vector, diminishing the scale of weights. Additionally, in many cases, the alteration in the weights' direction conveys more meaningful information, such as feature learning and representation, compared to the magnitude of change.

The implementation of SLERP involves the following steps:

- Normalize the input vectors to unit length, ensuring they signify directions rather than magnitudes.
- Calculate the angle between these vectors using their dot product.
- If the vectors are nearly collinear, the method defaults to linear interpolation for efficiency. Otherwise, SLERP calculates scale factors based on the interpolation factor t (where t=0 corresponds to 100% of the first vector, and t=1 corresponds to 100% of the second vector) and the angle between the vectors.
- Utilize these computed factors to weigh the original vectors, and then sum them to derive the interpolated vector.
